Description

Technical Field

[0001] This utility model relates to the field of fuel cell clamping technology, specifically a fuel cell clamping device. Background Technology

[0002] A fuel cell is an energy conversion device that directly converts the chemical energy of fuels (such as hydrogen, natural gas, methanol, etc.) into electrical energy. It belongs to electrochemical cells and generates current through redox reactions. Compared with traditional combustion processes, it has higher energy conversion efficiency and can significantly reduce pollutant emissions.

[0003] Fuel cells require specialized clamps for clamping and securing during manufacturing and transportation. However, traditional fuel cell clamps typically use multiple cylinders to control the longitudinal clamping rods to move in opposite directions to hold and secure the fuel cell. While the clamping rods have protective pads on their surfaces to protect the fuel cell's outer surface, they lack supporting structures at the bottom. As a result, the fuel cell can easily slip under its own weight during clamping, positioning, and transportation, potentially causing it to fall and become damaged, posing a safety hazard. To address these issues, we propose a fuel cell clamp to solve the aforementioned problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Figure 1-5 As shown, this utility model provides a fuel cell clamp, including a first frame 1, a second frame 2 on one side of the first frame 1, two symmetrically distributed sliding blocks 3 slidingly mounted on both the first frame 1 and the second frame 2, a first telescopic cylinder 31 fixedly mounted on the side of the first frame 1 and the second frame 2 near the sliding blocks 3, the drive end of the first telescopic cylinder 31 and the corresponding sliding block 3 fixedly mounted, a side clamp 4 provided in the middle of the sliding block 3, and a fixing member 6 fixedly mounted on the top of the first frame 1 near the side of the second frame 2.

[0026] The side clamp 4 includes a side clamping rod 41. The top of the side clamping rod 41 is movably engaged with the middle of the corresponding sliding block 3. Two fastening nuts 42 are threaded on the top of the side clamping rod 41. The sliding block 3 is located between the two fastening nuts 42, and the side clamping rod 41 is fixed by the two fastening nuts 42.

[0027] A side support rod 43 is movably mounted at the bottom center of the side clamping rod 41. Protective pads 45 are fixedly installed on the outer walls of both the side clamping rod 41 and the side support rod 43. These protective pads protect the outer wall of the clamped and positioned fuel cell. A drive horizontal shaft 431 is fixedly mounted on the top of the side support rod 43. The drive horizontal shaft 431 is rotatably mounted on the side clamping rod 41. A worm gear 44 is fixedly mounted on one end of the drive horizontal shaft 431. A worm 441 is meshed with the outer side of the worm gear 44 and rotatably mounted on the outer side of the side clamping rod 41. The outer wall of the side clamping rod 41 is close to the worm. A drive motor 442 is fixedly installed on one side of 441. The drive end of the drive motor 442 and the top end of the worm gear 441 are fixedly installed. By controlling the start of the drive motor 442, the worm gear 441 drives the worm wheel 44 and the drive horizontal shaft 431 to rotate. This, in turn, controls the side support rod 43 to rotate at the bottom center of the side clamping rod 41. This allows the side support rod 43 to rotate and contact the lower surface of the fuel cell. The side support rod 43 supports the bottom of the fuel cell, preventing the fuel cell from slipping during clamping, positioning and transportation, which could cause the fuel cell to fall and be damaged.

[0028] The first frame 1 has guide rails 5 fixedly installed on its side ends, and the second frame 2 has guide rail seats 51 corresponding to the guide rails 5 fixedly installed on its side ends. The guide rails 5 are slidably engaged with the ends of the corresponding guide rail seats 51. The second telescopic cylinder 52 is fixedly installed in the middle of the first frame 1. The drive end of the second telescopic cylinder 52 is fixedly installed in the second frame 2. According to the length of the fuel cell, the distance between the first frame 1 and the second frame 2 is adjusted. The second telescopic cylinder 52 is opened to extend and drive the second frame 2 to slide horizontally away from the first frame 1, thereby increasing the distance between the first frame 1 and the second frame 2 to accommodate the clamping and positioning of longer fuel cells. The second telescopic cylinder 52 is opened to extend and drive the second frame 2 to slide horizontally closer to the first frame 1, thereby reducing the distance between the first frame 1 and the second frame 2 to accommodate the clamping and positioning of shorter fuel cells.

[0029] The fixing component 6 includes two symmetrically distributed connecting brackets 61, which are fixedly installed on the top of the first frame 1 near the second frame 2. A transverse slide 62 is fixedly installed on the top of the connecting brackets 61. A transverse slide groove 621 is provided on the transverse slide groove 621, and a fixed crossbar 63 is slidably engaged in the transverse slide groove 621. By providing the transverse slide groove 621, the fixed crossbar 63 can be easily moved and slid in the transverse slide groove 621, thereby adjusting the position of the fixed crossbar 63. The fixed crossbar 63 can be flexibly positioned in the middle of the total weight of the fuel cell after the entire fixture clamps it. The position is designed to prevent tilting during subsequent transport of the fuel cell, thus improving the stability of the entire clamp after holding the fuel cell. Both ends of the fixed crossbar 63 are threaded with fixing nuts 632, which contact the side ends of the transverse slide 62. The fixed crossbar 63 is fixed by fixing nuts 632. The middle of the fixed crossbar 63 is fixedly installed with a mounting bracket 631, which is connected to an external hoisting and transport mechanism to control the external hoisting and transport mechanism and control the entire clamp to hold the fuel cell for transport.

[0030] Working principle: In use, the entire clamp is connected to the external hoisting and transportation mechanism through the mounting frame 631. Then, according to the different lengths of the fuel cell, the distance between the first frame 1 and the second frame 2 is adjusted. The second telescopic cylinder 52 is opened to extend and drive the second frame 2 to slide and translate away from the first frame 1, thereby increasing the distance between the first frame 1 and the second frame 2 to accommodate the clamping and positioning of longer fuel cells. The second telescopic cylinder 52 is opened to extend and drive the second frame 2 to slide and translate closer to the first frame 1, thereby decreasing the distance between the first frame 1 and the second frame 2 to accommodate the clamping and positioning of shorter fuel cells.

[0031] After adjustment, the fuel cell is clamped and positioned, and placed between multiple side clamps 4 on the first frame 1 and the second frame 2. Then, the corresponding multiple first telescopic cylinders 31 are activated to drive the corresponding card slide 3 and side clamping rods 41 to move towards each other until the top of the multiple side clamping rods 41 contacts the outer wall of the fuel cell, and the multiple side clamping rods 41 clamp the fuel cell.

[0032] Subsequently, the drive motor 442 is activated to control the worm gear 441 to drive the worm wheel 44 and the drive shaft 431 to rotate, thereby controlling the side support rod 43 to rotate at the bottom center of the side clamping rod 41. This allows the side support rod 43 to rotate and contact the lower surface of the fuel cell, thus supporting the bottom of the fuel cell and preventing it from slipping during clamping, positioning and transportation, which could cause the fuel cell to fall and be damaged.

[0033] Subsequently, the fixed crossbar 63 is slid and moved in the transverse sliding groove 621 to adjust the position of the fixed crossbar 63 until the fixed crossbar 63 is located at the middle position of the total weight of the fuel cell after the entire fixture clamps it. The adjusted fixed crossbar 63 is then fixed by the fixing nut 632 to prevent tilting during subsequent transport of the fuel cell and to improve the stability of the entire fixture after transporting the fuel cell.

[0034] Control the external hoisting and transportation mechanism to control the entire clamp to hold the fuel cell for transportation.
