Description

Technical Field

[0001] This utility model relates to the field of hydrogen energy storage tank technology, and more specifically, to a safety anti-collision device for transporting hydrogen energy storage tanks. Background Technology

[0002] A safety anti-collision device for transporting hydrogen storage tanks is defined as a safety device designed to protect hydrogen storage tanks from external forces such as collisions and impacts during transportation. This device is typically installed on the exterior of the hydrogen storage tank or on the transport vehicle, using specific structures and materials to absorb, disperse, or transfer the impact force generated by a collision, thereby ensuring the safety and stability of the hydrogen storage tank during transportation. In existing technologies, when using mounting frames for anti-collision in hydrogen storage tank transportation, problems such as insufficient connection strength and insufficient bending stiffness may arise. During a collision, if the mounting frame's connection strength is insufficient, it is prone to deformation or breakage due to impact force, leading to the failure of the anti-collision device. The original frame's connection to the vehicle body may also suffer from insufficient connection strength due to large collision deformation. Furthermore, if the mounting frame's bending stiffness is insufficient, it is prone to bending or twisting during a collision, affecting anti-collision performance. Especially in rear-end collisions, the long load-bearing length of the rear crossbeam and insufficient bending stiffness will exacerbate damage to the hydrogen storage tank. These problems all pose a potential threat to the safe transportation of hydrogen storage tanks and require attention and improvement. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. Compared with traditional devices, this utility model, through the cooperation of the moving block, the second spring, and the third spring, can respond quickly when a vehicle encounters a collision or bump. It uses the elasticity of the second spring and the displacement of the moving block to absorb and disperse the impact force, significantly reducing the direct impact on the hydrogen storage tank and protecting it from damage. At the same time, the cooperation between the third spring and the moving block ensures the stability of the anti-collision device under force and avoids failure.

At the same time, the arc-shaped clamping plate not only serves as a fixing device but also provides additional anti-collision protection for the hydrogen storage tank. When the vehicle encounters bumps or collisions, it can absorb and disperse the impact force, reducing the direct impact on the storage tank and significantly reducing the risk of damage to the hydrogen storage tank during transportation. This design, which integrates clamping stability and anti-collision protection, provides a strong guarantee for the safe transportation of hydrogen storage tanks. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] like Figures 1 to 6 As shown, this utility model provides a safety anti-collision device for transporting hydrogen energy storage tanks, including a transport vehicle 1, a fixed box 2 fixedly installed on the top of the transport vehicle 1, a fixed plate 9 fixedly installed inside the fixed box 2, a fixed block 14 fixedly installed on the outside of the fixed plate 9, a fixed shaft 28 fixedly installed inside the two fixed blocks 14, a movable block 15 movably installed on the outer surface of the fixed shaft 28, a second spring 16 fixedly installed between the two movable blocks 15, and a third spring 17 fixedly installed between the fixed block 14 and the movable block 15.

[0025] A first telescopic rod 12 is fixedly installed on the outer side of the fixed plate 9. A crash plate 8 is fixedly installed at one end of the first telescopic rod 12. A first spring 13 is fixedly installed between the crash plate 8 and the fixed plate 9. A second fixed block 18 is fixedly installed on the inner side of the crash plate 8. A third spring 17 is hinged between the second fixed block 18 and the moving block 15.

[0026] When the fixed box 2 receives an impact, it compresses the anti-collision plate 8, which in turn compresses the second fixed block 18, which in turn compresses the third spring 17, which in turn compresses the moving block 15. This causes the moving block 15 to compress the second spring 16 and the third spring 17 on the outer surface of the fixed shaft 28. The fixed shaft 28 is supported by the first fixed block 14, and the first telescopic rod 12 and the first spring 13 are simultaneously compressed by the anti-collision plate 8, thus completing the safety anti-collision of the hydrogen energy storage tank.

[0027] When the fixed tank 2 is impacted, it compresses the anti-collision plate 8, which in turn pushes the fixed block 18 to compress the third spring 17. The reaction force of this spring compresses the second spring 16 and the third spring 17 on the fixed shaft 28 through the moving block 15. At the same time, the anti-collision plate 8 also compresses the first telescopic rod 12 and the first spring 13. Throughout the process, the fixed block 14 provides support for the fixed shaft 28. Compared with traditional devices, this device, through the cooperation between the moving block 15, the second spring 16, and the third spring 17, can respond quickly when the vehicle encounters a collision or bump. It uses the elasticity of the second spring 16 and the displacement of the moving block 15 to absorb and disperse the impact force, significantly reducing the direct impact on the hydrogen storage tank and protecting it from damage. At the same time, the cooperation between the third spring 17 and the moving block 15 ensures the stability of the anti-collision device under force and avoids failure. In addition, the anti-collision device is flexibly designed and can be adapted to hydrogen storage tanks of different sizes and shapes by adjusting parameters such as the length of the connecting rod, the spring stiffness, and the shape of the moving block, so as to achieve precise clamping and comprehensive anti-collision protection.

[0028] The fixed box 2 has a fixed seat 10 inside, the fixed seat 10 has a sliding groove 29 inside, the sliding groove 29 has a sleeve block 26 inside, the sleeve block 26 has a double-ended screw 27 threaded inside, and the two ends of the double-ended screw 27 pass through the inside of the fixed seat 10. The fixed seat 10 has a motor 24 fixedly installed on the outside, and the output end of the motor 24 is fixedly connected to the double-ended screw 27.

[0029] A movable plate 19 is fixedly installed on the top of the sleeve block 26. A telescopic rod 20 is fixedly installed on the inner side of the movable plate 19. An arc-shaped clamping plate 22 is fixedly installed at one end of the telescopic rod 20. A fourth spring 21 is fixedly installed between the arc-shaped clamping plate 22 and the telescopic rod 20.

[0030] Before transporting the hydrogen storage tank, the staff needs to clamp and fix it. First, move the hydrogen storage tank to the bottom of the fixing base 10, and then turn on the motor 24. The motor 24 drives the bidirectional lead screw 27 to rotate inside the sleeve block 26, so that the two sleeve blocks 26 slowly move closer to the hydrogen storage tank inside the slide groove 29. The sleeve blocks 26 drive the moving plate 19 to move, and the moving plate 19 drives the fourth spring 21 and the arc-shaped clamping plate 22 to move. The fourth spring 21 and the telescopic rod 20 drive the arc-shaped clamping plate 22 to clamp and fix the hydrogen storage tank, thus completing the clamping and fixing of the hydrogen storage tank.

[0031] Before transporting the hydrogen storage tank, it needs to be clamped and secured. First, the hydrogen storage tank is moved to the bottom of the mounting base 10. Then, the motor 24 is turned on, driving the bidirectional lead screw 27 to rotate inside the sleeve block 26. This causes the two sleeve blocks 26 to slowly approach the hydrogen storage tank inside the sliding groove 29. The sleeve blocks 26 then move the moving plate 19, which in turn moves the fourth spring 21 and the arc-shaped clamping plate 22. The fourth spring 21 and the telescopic rod 20 then move the arc-shaped clamping plate 22 to clamp and secure the hydrogen storage tank. Compared to traditional devices, this device uses the sleeve block 26 and the bidirectional lead screw 27... The coordinated action between the components facilitates the clamping of the arc-shaped clamping plate 22 to secure the hydrogen storage tank. This design perfectly conforms to the outer surface of the hydrogen storage tank, and the clamping effect is particularly significant when the curvature matches, effectively reducing shaking during transportation and significantly improving transportation safety. At the same time, the arc-shaped clamping plate 22 not only serves as a fixing device but also provides additional anti-collision protection for the hydrogen storage tank. When the vehicle encounters bumps or collisions, it can absorb and disperse the impact force, reducing the direct impact on the storage tank and significantly reducing the risk of damage to the hydrogen storage tank during transportation. This design, which integrates clamping stability and anti-collision protection, provides a strong guarantee for the safe transportation of hydrogen storage tanks.

[0032] Among them, the bottom of the transport vehicle 1 is movably equipped with wheels 3, and a first rotating shaft 6 is fixedly installed between the two wheels 3.

[0033] The cooperation between the wheels 3 and the first rotating shaft 6 facilitates the transportation of the transport vehicle 1, enabling rapid movement of the transport vehicle 1. The transport vehicle 1 then drives the fixed container 2 and the hydrogen storage tank for transportation, ensuring efficient transportation of the hydrogen storage tank.

[0034] The support base 25 is fixedly installed on the outer side of the fixed base 10, and the interior of the support base 25 has a U-shaped form.

[0035] Because the inside of the support base 25 is U-shaped on the outside of the fixed base 10, the support base 25 provides stable support for the motor 24, reduces the shaking of the motor 24 during use, improves the stability of the motor 24 during use, and extends the service life of the motor 24.

[0036] The inner side of the arc-shaped clamping plate 22 is fixedly equipped with an anti-slip pad 23, which is made of rubber.

[0037] Because the anti-slip pad 23 is made of rubber and is located on the inner side of the arc-shaped clamping plate 22, the arc-shaped clamping plate 22 drives the anti-slip pad 23 to fit tightly against the outer surface of the hydrogen energy storage tank, thus preventing the hydrogen energy storage tank from shaking during transportation and improving the stability of the hydrogen energy storage tank during transportation.

[0038] The top of the fixed base 10 is fixedly installed with a support block 11, and the support block 11 has two shapes of the same size.

[0039] Since the support blocks 11 are two identical shapes at the bottom of the fixing base 10, they provide stable support for the hydrogen energy storage tank and reduce the shaking of the hydrogen energy storage tank during use.

[0040] The fixed box 2 has a fixed groove 7 inside, and a second rotating shaft 4 is fixedly installed inside the fixed groove 7. A toolbox 5 is fixedly installed on the left side of the second rotating shaft 4.

[0041] By holding the toolbox 5, the second rotating shaft 4 is slowly inserted into the fixed groove 7. The fixed groove 7 then limits and fixes the second rotating shaft 4. By adding the toolbox 5, it is easier for workers to take out and place maintenance tools inside the toolbox 5.

[0042] Working principle and usage process of this utility model:

[0043] When the fixed box 2 receives an impact, it compresses the anti-collision plate 8, which in turn compresses the second fixed block 18, which in turn compresses the third spring 17, which in turn compresses the moving block 15. This causes the moving block 15 to compress the second spring 16 and the third spring 17 on the outer surface of the fixed shaft 28. The fixed shaft 28 is supported by the first fixed block 14, and the first telescopic rod 12 and the first spring 13 are simultaneously compressed by the anti-collision plate 8, thus completing the safety anti-collision of the hydrogen energy storage tank.

[0044] Before transporting the hydrogen storage tank, the staff needs to clamp and fix it. First, move the hydrogen storage tank to the bottom of the fixing base 10, and then turn on the motor 24. The motor 24 drives the bidirectional lead screw 27 to rotate inside the sleeve block 26, so that the two sleeve blocks 26 slowly move closer to the hydrogen storage tank inside the slide groove 29. The sleeve blocks 26 drive the moving plate 19 to move, and the moving plate 19 drives the fourth spring 21 and the arc-shaped clamping plate 22 to move. The fourth spring 21 and the telescopic rod 20 drive the arc-shaped clamping plate 22 to clamp and fix the hydrogen storage tank, thus completing the clamping and fixing of the hydrogen storage tank.
