Description

Technical Field

[0001] This utility model relates to the field of fuel cell stack transportation technology, and in particular to a shockproof transportation device for fuel cell stacks. Background Technology

[0002] A battery stack is not an actual collection of batteries placed together, but rather a fuel cell term referring to a stack of multiple fuel cells. The purpose is to obtain the voltage required for practical applications. The key to a battery stack lies in the materials and manufacturing technology that make up the stack. The materials must have sufficient chemical and thermal stability, the electrochemical performance must meet the requirements, and all technical conditions must be consistent.

[0003] For example, Chinese utility model patent CN217533737U includes a base plate with through holes on both the front and back. A buffer assembly is installed inside each through hole. Four elastic components are located on the top of the base plate. A top plate is fixed between the four elastic components and two buffer components. An adjustment assembly is located on the top of the top plate, with two clamping plates fixed to its top. Anti-slip pads are fixed to opposite sides of each clamping plate. Positioning cylinders are fixed to both the front and back of each clamping plate, and positioning components are installed outside the positioning cylinders. Limiting components are installed between the two front positioning cylinders and the two back positioning cylinders. This fuel cell stack transport assembly, through the cooperation between the structures in the buffer and elastic components, effectively improves the cushioning of the base plate during transport, thus effectively improving the protection of the fuel cell stack body during transport and preventing damage to the fuel cell stack body due to vibration.

[0004] However, when fixing the fuel cell stack after placement, not only can the screw be rotated to control the two clamps to fix the fuel cell stack, but in actual use, due to the limited rotation speed of the screw and the further deceleration of the clamps relative to the screw, the speed of controlling the clamps to clamp and fix the fuel cell stack is relatively slow, which has certain shortcomings. In view of this, we propose a shockproof transportation device for fuel cell stacks. Utility Model Content

[0011] Preferably, mounting cylinders are fixedly connected to the front and rear surfaces of the left-side clamping plate, and torsion springs are fixedly connected to the inner walls of the mounting cylinders.

[0012] Preferably, the end of the torsion spring away from the mounting cylinder is fixedly connected to a rotating shaft, the end of the rotating shaft rotatably passes through the mounting cylinder, the end of the rotating shaft is fixedly connected to a first locking plate, the lower surface of the first locking plate is provided with an inclined groove extending out of its front and rear sides, and the front and rear sides of the right clamping plate are respectively rotatably connected to a second locking plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1.

[0016] 2. The shockproof transport device for the fuel cell stack, through the cooperation of the first locking plate and the second locking plate, can further fix the fuel cell stack after the clamping plate holds it, avoiding the problem of displacement of the clamping plate due to vibration and bumps, and improving the stability after fixation.

A shock-absorbing component 2 is provided on the upper surface of the base plate 1. A mounting plate 3 is fixedly connected to the upper surface of the shock-absorbing component 2. Two limiting grooves 4 are formed on the upper surface of the mounting plate 3. Two clamping plates 5 are provided on the mounting plate 3. The lower surfaces of the two clamping plates 5 extend into the interior of the limiting grooves 4 and are slidably connected to the limiting grooves 4. A pressure plate 6 is provided above the mounting plate 3. Four connecting rods 7 are rotatably connected to the lower surface of the pressure plate 6. Four sliding grooves 8 are formed on the upper surface of the mounting plate 3. The device is equipped with sliding blocks 9. The sliding blocks 9 located in the front and rear sliding grooves 8 are located on the right side of the pressure plate 6, and the sliding blocks 9 located in the middle two sliding grooves 8 are located on the left side of the pressure plate 6. The front and rear connecting rods 7 are rotatably connected to the front and rear sliding blocks 9 respectively, and the middle two connecting rods 7 are rotatably connected to the middle two sliding blocks 9. The sliding blocks 9 are equipped with fixing components. The pressure plate 6 is driven down by the gravity of the fuel cell stack itself, and then the fixing components automatically drive the two clamping plates 5 to move closer to each other to complete the clamping of the fuel cell stack. This avoids the problem of slow clamping speed in traditional structures using lead screws and improves the fixing efficiency.

[0026] Furthermore, the fixing assembly includes a pull rod 10, which is fixedly connected to the side surface of the sliding block 9 away from the clamping plate 5. Two protrusions 11 extending into the front and rear sliding grooves 8 are fixedly connected to the lower surface of the left clamping plate 5. Two protrusions 11 extending into the middle two sliding grooves 8 are fixedly connected to the lower surface of the right clamping plate 5. A sleeve 12 is fixedly connected to the end of the pull rod 10 near the protrusions 11. An extension rod 13 is slidably connected inside the sleeve 12. A spring 14 is fixedly connected between the extension rod 13 and the inner wall of the sleeve 12. The end of the extension rod 13 near the protrusions 11 slides through the sleeve 12 and is fixedly connected to the protrusions 11. Buffer pads 15 are fixedly connected to the adjacent surfaces of both clamping plates 5. Mounting cylinders 16 are fixedly connected to the front and rear surfaces of the left clamping plate 5, respectively. Torsion springs 17 are fixedly connected to the inner walls of the mounting cylinders 16. A torsion spring 17 is fixedly connected to a rotating shaft 18 at the end away from the mounting cylinder 16. The end of the rotating shaft 18 rotates through the mounting cylinder 16. A first locking plate 19 is fixedly connected to the end of the rotating shaft 18. The lower surface of the first locking plate 19 has a groove 20 extending from its front and rear surfaces.

[0027] The shock absorption component 2 mentioned in the article is an existing structure, and for details, please refer to patent publication number CN217533737U.

[0028] Working principle: When the fuel cell stack is fixed, it is placed on the pressure plate 6. The pressure plate 6 descends under pressure, and as it descends, it simultaneously moves the four connecting rods 7, driving the four sliding blocks 9 to move. Since each sliding block 9 is connected to a clamping plate 5 that is relatively far away from it, the movement of the sliding block 9 will automatically drive the two clamping plates 5 to move closer to each other. At the same time, with the movement space provided by the sleeve 12, spring 14, and extension rod 13, a certain buffer distance can be provided after the clamping plates 5 clamp the fuel cell stack, preventing damage to the fuel cell stack due to excessive clamping. Additionally, the buffer pad 15 provides some protection for the fuel cell stack, and after clamping, the first... First, rotate the first locking plate 19 from a horizontal position to a horizontal position. When the first locking plate 19 rotates, it will simultaneously drive the rotating shaft 18 to rotate, thereby compressing the torsion spring 17 with the help of the rotating shaft 18. Then, rotate the second locking plate 21 so that the second locking plate 21 is in a horizontal state. Since the lower surface of the second locking plate 21 is in contact with the limiting block 23 at this time, it cannot continue to rotate. Then, release the first locking plate 19, and the first locking plate 19 will return to a horizontal state with the help of the elastic force of the torsion spring 17. At this time, the locking shaft 22 enters the interior of the inclined groove 20 to complete the locking, preventing the clamping plate 5 from loosening due to vibration.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
