On the morning of 15 July, the high-voltage shore power robot independently developed by Shandong Port Qingdao Port Automated Terminal was officially put into use, with its all-autonomous research and development, all-terrain passage, more convenient operation, safer operation, more compact structure, more environmentally applicable capacity, connecting distance, and other significant advantages, to help the terminal shore power connected to the ship more efficiently and more conveniently. It effectively promotes win-win situation between environmental protection and economic development, and win-win situation between port shipping and urban development. "Model of the Times" and "Liangang Innovation Team" once again set up a benchmark demonstration for ports, lead the construction of green and low-carbon ports, and create a brand-new model for promoting the practical application of Carbon Dafeng Carbon Neutral Port. A brand new model has been created to promote the practical application of carbon neutral ports.
New equipment, empowering green and low-carbon port construction
At the operation site of Qingdao Port Automated Terminal of Shandong Port, a small crawler tank with wireless remote control is shuttling between the ship and the high-voltage shore power socket box, supplying shore power to the ship, which constitutes an all-around green equipment matrix with photovoltaic shore bridge, photovoltaic sunflower, and wind-solar complementary street lamps at the site.
It is understood that in the terminal shore power even ship operations, about 25% of the ship because of the high-voltage shore power cable length is insufficient and other issues lead to the inability to connect the power on demand. Currently on the market, only a foreign company has a similar complete set of high-voltage shore power mobile power supply equipment, but relative to the actual application of the dock site scene, the equipment is larger, inconvenient to operate, connect the length of the connection is insufficient, the construction cycle is long, expensive and other factors, unable to meet the demand for the use of ship shore power connected to the ship.
To this end, the Shandong Port of Qingdao Port Automated Terminal set of wisdom to break the situation, the technical staff before and after more than three months, independent development of research and development of high-voltage shore power suitable for large container terminals on their own robot.
All independent research and development: from the product conception to the design of the configuration of all by the terminal technicians to complete the equipment to use all the parts from domestic, collective wisdom to attack the problem, the first in the industry;
All-terrain passage: the innovative rubber track walking mechanism design makes the equipment run more smoothly, and it can comfortably cope with all kinds of terrains at the operation site;
More convenient operation and safer operation: adopting remote control operation by personnel and separating man and machine to avoid the hidden safety danger caused by the interaction between personnel and equipment;
More compact structure and stronger environmental adaptability: adopting non-slip-ring structure reel and vertical layout design of plug-in interface, making the whole machine structure more compact, breaking through the limitation of shore operation space of the container terminal, and allowing barrier-free cross operation with the terminal loading and unloading equipments;
Connection distance is farther: the use of multi-column multi-layer large cable coil cable mode, help equipment load connection cable length of more than 2 times the length of similar products, to meet the needs of all types of ships full berth even ship.
It is reported that the high-voltage shore power on its own robot test phase has been completed shore power connection 271,000 kW - h, reducing carbon dioxide emissions 239.6 tonnes, formally put into operation to meet the needs of all types of ships high-voltage shore power connected to the ship scenario, the shore power connection rate of more than 25%, is expected to be completed throughout the year the shore power connection of 2.6 million kW - h, to reduce carbon dioxide emissions of 2,299.18 tonnes. With scientific and technological innovation to continuously improve the port power supply capacity of shore power, and make every effort to build a clean and low-carbon, intelligent and efficient green logistics and transport system.
Gathering wisdom and attacking with courage to start a new situation
General Secretary Xi Jinping stressed the need to "support high-quality development with a high-quality ecological environment, and accelerate the modernisation of harmonious coexistence between human beings and nature". Shandong Port Qingdao Port Automated Terminal has always adhered to the "green concept of full staff, low-carbon transport structure, clean energy applications, resource use intensive, energy-efficient management of wisdom", in promoting ecological environmental protection and green port construction journey, to collect wisdom to break new ground, open a new situation.
On 23 January, a foreign ship berthed at Qingdao Port Automated Terminal of Shandong Port.
"The connection position has not yet been reached, please continue to put down the cable ......" The terminal technician communicated with the ship to put down the shore power cable through the walkie-talkie. "Can't put any more, the ship's cable winch has reached its limit." At this time, put down to the ground on the cable from the shore outlet box only less than 5 metres left, the adjacent berth ships are also in normal operation, under the helplessness of the ship's shore power even the ship can be pushed back.
In order to be able to completely solve this problem, to help different ships to complete the terminal full berth power needs, terminal technicians actively study the technical transformation of shore power facilities, but in the face of the operating site of various types of equipment interaction, underground pipe network intricacies, and other realities, the transformation work was once in a stalemate. At this time, the team members proposed to directly buy the cable mobile connection equipment on the market, but after a number of research comparisons found that its high price, cable length is limited, large size, long production cycle, equipment and shore-side loading and unloading machinery production operations mutual constraints, unable to meet the needs of the actual operation of large container terminals.
When we are at a loss, Pan Haiqing, deputy manager of the engineering department, took the initiative to come forward "Dare to be the first, desperately innovative, has always been our 'Liangang innovation team' heirloom. There is no suitable equipment, we will build a device out of their own!" He made a military order, within three months must be through independent innovation to come up with a new equipment in line with the actual production needs of the terminal.
Seemingly ordinary most strange, into as easy but hard. The road of innovation is difficult and bumpy, needless to say.
High-voltage shore power cable reeling equipment needs to be used in the dock shore, due to the shore waves, sea breeze and other factors, the equipment needs to have sufficient self-protection performance and structural stability; shore compact space layout, to completely avoid the cross impact with the shore loading and unloading machinery operations, the structure of the new equipment puts forward a higher demand for compactness, while the structure of the compactness of the length of the cable and the load capacity and the contradiction, which requires a variety of constraints between the argumentative study of a new equipment, and the cable length and load capacity. It is necessary to argue between the various constraints to study a technical balance point ...... In the face of a difficult problem, the team members take out the spirit of "desperation + innovation", "open" on the project. During the day, they measured the shoreline with their feet, carefully observed the shore loading and unloading machinery operation scene, repeated measurements of the various space requirements of the dock shore loading and unloading machinery operation, and constantly mapping, sorting out the ship's high-voltage shore power configuration and power load data, cable selection and other key data; at night, they live and eat in the company, summing up the data, drawing the design drawings, the cable reel, the drive system, the electric control system, the travelling mechanism ...... each draft design drawings should be compared on-site simulation, each modification involves changes in the overall programme, design drawings one draft after another, members of the Bidongjie is 2 days and 2 nights in a row to rely on the site for programme verification and optimization. In the team's unremitting efforts, the successful development of the cable reeling mechanism, the cable length is two times the length of similar products, its structure size reduced by 30%, to meet the needs of all types of ships high-voltage shore power all berths connected to the ship.
After the successful development of the cable reeling mechanism, members of the focus of the attack aimed at the equipment walking mechanism. After continuous deduction, they found that the walking mechanism in the design of the cable with the cable winding mechanism between the existence of subtle component conflicts, the need to disassemble all the parts of the equipment redesign assembly, or may cause the equipment can not be completed on time assembly. Seeing the distance from the original set assembly time is getting closer and closer, we are anxious, after how many days and nights of struggle, not until the last moment of everyone's heart do not dare to put down easily. "Time is life. We can't leave it to chance, we must keep an eye on the scene to ensure that the assembly is foolproof." Pan Haiqing with on-site measurement data and summary of the optimisation program, overnight rush more than 1,000 kilometres to the field parts factory workshop, on-site guidance to the equipment walking structure, modification and optimisation, and ultimately after three months on schedule to complete the assembly of the equipment to be used than similar foreign products to shorten the manufacturing cycle of more than 6 months.
Grass planted into the wealth of the country. Green ecology is the biggest wealth, the biggest advantage, the biggest brand. Looking to the future, Qingdao Port Automated Terminal of Shandong Port will actively practice the new development concept, adhere to the principle that "green water and green mountains are golden silver mountains", lock the target of "double carbon", and implement the green concept of full staffing, low-carbon transport structure, cleaner energy application, intensive resource utilisation, and intelligent energy efficiency management. Intensification of transport structure, cleaner energy application, resource utilisation, intelligent energy efficiency management, speeding up the race on the "green" track, striving to realise the "beauty and harmony" between port development and ecology and nature, and adding colour to the picture of "Beautiful China" with its hardcore commitment. and add colour to the picture of "Beautiful China" with its hard-core commitment.
