Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen fuel cell system assembly and production, in particular to a hydrogen fuel cell system delivery bracket auxiliary device. Background Art

[0002] At present, the development and application of hydrogen fuel cells (stacks) have been the focus of governments and enterprises around the world. Hydrogen fuel cells (stacks) have the advantages of high fuel energy conversion rate, low noise and zero emissions, and can be widely used in vehicles such as cars, airplanes, trains and fixed power stations. In the future, when the proportion of coal-fired power is relatively low, the entire upstream power structure will become cleaner due to the increase in the scale of renewable energy technologies such as wind power and solar power. Compared with the current traditional combustion technology, fuel cells (stacks) have several advantages:

[0003] 1. The power generation efficiency is as high as 50% to 60%. If it can be combined to form a circulating power generation system, its power generation efficiency can be as high as 70% or more;

[0004] 2. Compared with traditional thermal power generation, fuel cells have lower environmental pollution;

[0005] 3. Fuel cells do not generate much noise during operation because they have few internal components. The general noise is 50dB to 70dB.

[0006] 4. Electricity generated by wind and solar energy that cannot be connected to the grid can be used to produce hydrogen, and hydrogen can be used to generate electricity through fuel cells (fuel stacks). In terms of the upstream and downstream energy chain, this process is purely green and pollution-free. At the same time, hydrogen can be stored in large capacity for a long time, and can achieve continuous space-time dumping of energy, which is something that lithium batteries cannot achieve.

[0007] In actual production, to apply fuel cells (stacks) in actual scenarios, fuel cells (stacks) alone are far from enough. A relatively complex set of subsystems is also required, including fuel supply subsystem, oxidant supply subsystem, water and heat management subsystem, and electrical management and control subsystem, etc. Its main system components include air compressor, particulate filter, PTC heater, intercooler, high-temperature water pump, hydrogen injector, humidifier, hydrogen circulation pump, various fixed brackets, and base plates for installation and fixing, etc. These subsystems and fuel cells (or modules) constitute the fuel cell power generation system (hereinafter referred to as the system).

[0008] The system is assembled on a flip installation platform. First, the base plate is fixed on the flip installation platform, and then the air compressor, humidifier, throttle, particulate filter, fuel cell (stack), DC-DC and other components are installed and fixed. The time to complete all the above work is 2 hours / 1 person.

[0009] The traditional approach is to rotate the flip installation platform to a horizontal angle after all components are installed, loosen the bolts on the base plate, use a crane to lift the system to the offline turnover bracket, and with the cooperation of two people and the crane, use bolts to fix the base plate to the turnover bracket. The above work time is 30 minutes / 2 people.

[0010] Place the ground cow under the turnover bracket, lift it together with the turnover bracket and the system, and transport it to the airtight test bench for low-pressure monotonicity and airtightness tests to verify the sealing performance of the joints between each electric component and the valve body and pipeline. The test time is about 2.5 hours per person.

[0011] After the air-tightness test is passed, the turnover bracket and system 1 are transported to the system test bench in the Class A workshop by a ground ox. After the gas and water pipelines are connected and the circuits are connected, the hydrogen test and component calibration are carried out to complete the load calibration of the entire system. The above work time is about 2.5 hours per person.

[0012] After the calibration is qualified, the system is pulled back to the crane with a ground ox, and the system is lifted by the crane. With the cooperation of 2 people and the crane, the turnover bracket is removed and the bottom plate is fixed to the shipping bracket with bolts. The above work time is 30 minutes / 2 people, after which the subsequent finished product sorting, shipping and delivery work are carried out.

[0013] During the entire working process, the system needs to be transported multiple times through the turnover bracket, which consumes a lot of manpower and time costs, and the turnover bracket also needs to occupy a large storage space when idle. Utility Model Content

[0036] See also Figures 1 to 4 As shown, according to an embodiment of the utility model, the hydrogen fuel cell system shipping bracket auxiliary device includes: an off-ground support frame, including at least two base frames, at least two base frames extend in a vertical direction, and a forklift space is formed between the at least two base frames; a transport bracket, installed on the top of the off-ground support frame, and fixedly connecting at least two base frames together, and a connecting structure for detachably connecting to the shipping bracket is provided on the transport bracket.

[0037] The hydrogen fuel cell system shipping bracket auxiliary device uses an off-ground support frame to form a forklift space at the bottom of the auxiliary device, and uses a transport bracket to form a structure fixedly connected to the shipping bracket, which can replace the function of the turnover bracket. In the production process after the system is assembled, the auxiliary device is installed on the shipping bracket, and the shipping bracket can be used to complete all the work after the system is assembled.

The time for loading and unloading general devices is very short, which greatly improves production efficiency. The auxiliary device has a small structure and occupies less space, so it also reduces storage space.

[0038] In one embodiment, a single chassis includes two vertical beams 1 spaced apart along the fork transport direction, the transport bracket includes two oppositely arranged connecting beams 2 and a cross beam 3 connected between the two connecting beams 2, and the chassis is arranged at the bottom of the connecting beams 2 to support the connecting beams 2.

[0039] In this embodiment, a single base frame includes two vertical beams 1, and two base frames include four vertical beams 1. The four vertical beams 1 are arranged in parallel to form a four-point support, so that the bottom of the auxiliary device forms a stable support structure, thereby ensuring the stability and reliability of the support structure of the auxiliary device.

[0040] In one embodiment, the four vertical beams 1 are square tubes with a certain length. The length of the four vertical beams 1 is set according to the specifications of the forklift 8. The length of the four vertical beams 1 constitutes the bottom height of the auxiliary device. The length of the four vertical beams 1 is the original height of the forklift 8 plus the lifting height, so that the forklift 8 can effectively meet the forklifting requirements in the forklifting space of the auxiliary device. The front-to-back spacing of the four vertical beams 1, that is, the distance along the forklifting direction of the forklift is about 150mm to 300mm, which is convenient for the upright standing of the auxiliary device and makes the auxiliary device not easy to tilt. The two vertical beams 1 of the same chassis are located on the same side of the auxiliary device, and the two chassis are located on the left and right sides of the auxiliary device. The spacing between the two chassis is 700mm to 800mm, which is convenient for the introduction of the lifting arm of the forklift 8.

[0041] In one embodiment, a supporting plate 4 is disposed at the bottom of the vertical beam 1 , and the supporting plate 4 extends outward from the bottom of the vertical beam 1 in a horizontal direction.

[0042] In this embodiment, by providing a support plate 4 at the bottom of the vertical beam 1, the support plate 4 can be used to increase the bottom support area of ​​the vertical beam 1, thereby further improving the stability of the bottom support structure of the vertical beam 1 and more effectively preventing the auxiliary device from tipping over during use.

[0043] In one embodiment, the supporting plate 4 is formed by turning the bottom of the vertical beam 1 outward, which has a simple structure, can be made of local materials, and has a lower cost.

[0044] In one embodiment, the support plate 4 and the vertical beam 1 are separately provided, and the support plate 4 is welded and fixed to the outer peripheral surface of the vertical beam 1 , which can improve the convenience and flexibility of the structural processing of the support plate 4 .

[0045] In one embodiment, a reinforcing plate is provided between the supporting plate 4 and the vertical beam 1. The reinforcing plate may be a triangular plate or a strip plate connected between the supporting plate 4 and the vertical beam 1. The reinforcing plate may further improve the structural stability between the supporting plate 4 and the vertical beam 1, and improve the stability and reliability of the overall structure of the auxiliary device.

[0046] In one embodiment, the connecting beam 2 comprises an angle steel, the angle steel comprises a vertical plate and a horizontal plate, the vertical plate is located on the inner side of the horizontal plate, and the horizontal beam 3 connects the two vertical plates.

[0047] In this embodiment, angle steel is used as the connecting beam 2. On the one hand, it is convenient to realize the fixed connection between the connecting beam 2 and the vertical beam 1, reduce the connection difficulty, improve the connection efficiency and the stability of the connection structure. On the other hand, it is convenient to process the connecting structure on the angle steel, and it is convenient to use the structure of the angle steel itself and the processed connecting structure to realize the fixed connection between the connecting beam 2 and the shipping bracket 7, thereby reducing the overall process cost.

[0048] In one embodiment, the connection structure includes a connection hole 5 provided on the transverse plate and a connection bolt 6 provided in the connection hole 5 .

[0049] In this embodiment, the connecting structure includes a connecting hole 5 and a connecting bolt 6. A hole structure matching the connecting hole 5 is provided on the shipping bracket 7. After the two are aligned, the auxiliary device and the shipping bracket 7 are fixed together by the connecting bolt 6. The structure is simple, the operation is convenient, and it is easy to assemble and disassemble.

[0050] The connection structure may also be a pin connection structure or a clamping fixing structure.

[0051] In one embodiment, the connecting hole 5 is a strip-shaped hole.

[0052] By using strip holes, the relative position between the shipping bracket 7 and the cross plate can be adjusted, thereby facilitating the position adjustment of the holes, so that the shipping bracket 7 and the auxiliary device can have a better correspondence effect, avoiding the problem of increased difficulty in assembling the shipping bracket 7 and the auxiliary device due to problems such as processing accuracy, and improving assembly efficiency.

[0053] In one embodiment, the length of the crossbeam 3 can be adjusted, so that the distance between the connecting beams 2 on both sides can be adjusted, and the shipping brackets 7 with different trajectories can be used, thereby improving the applicability of the auxiliary device 11.

[0054] In one embodiment, the cross beam 3 is a square tube, and the bottom surface of the square tube is flush with the top surface of the cross plate.

[0055] In this embodiment, the crossbeam 3 is a square tube, and the two ends are fixedly connected to the vertical plates of the connecting beam 2 by welding or bolting. The square tube structure is used as the crossbeam 3, so that the crossbeam 3 has greater structural strength and can more effectively bear the gravity of the shipping bracket 7 and the fuel cell system 9 on the shipping bracket 7 during forklift transportation by the forklift 8.

[0056] The openings of the two angle steels are facing outward and are arranged in parallel, so as to support the delivery bracket 7 from the inside. The bottom surface of the square tube is higher than the lower surface of the angle steel. The height of the higher height is generally the thickness of the angle steel, for example, 5 mm, so that the bottom surface of the auxiliary device 11 and the lower surface of the delivery bracket 7 are in a plane, which is convenient for the stability of the forklift 8 during transportation. There are two sets of connecting holes 5 on the cross plate of the angle steel, which are convenient for connecting the auxiliary device 11 and the delivery bracket 7 with connecting bolts 6.

[0057] The method of using the hydrogen fuel cell system delivery bracket auxiliary device is as follows:

[0058] First, fix two auxiliary devices 11 to the front and rear ends of the delivery bracket 7 respectively, and fix the three with four connecting bolts 6, and use a crane to lift the fuel cell system 9 to the top of the delivery bracket 7. Use the fixing bolts 12 of the fuel cell system 9 to fix the bottom plate 10 on the fuel cell system 9 to the delivery bracket 7. After that, place the forklift 8 under the delivery bracket 7, raise the lifting arm of the forklift 8, and then lift the delivery bracket 7 and the fuel cell system 9 together, and transport them to the subsequent airtight test bench, load calibration bench, and finished product finishing station, and then carry out related construction work. After all the work is completed, use a crane to lift the fuel cell system 9 and the delivery bracket 7 as a whole, and then remove the connecting bolts 6 between the delivery bracket 7 and the auxiliary device 11, and the fuel cell system 9 can be finally packaged, and the auxiliary device 11 can be recycled next time.
