Description

Technical Field

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

[0002] Hydrogen energy, as a clean and efficient new energy source, relies on hydrogen storage tanks for its storage and transportation. However, due to their large weight and the flammable and explosive nature of the internal medium, the safety of hydrogen storage tanks (especially high-pressure gaseous tanks) during transportation has become one of the key bottlenecks in the promotion of the hydrogen energy industry.

[0003] Currently, hydrogen storage tank transportation mostly adopts traditional fixing methods: either the storage tank is directly and rigidly fixed to the transport vehicle with bolts, or it is limited by simple brackets.

[0004] Traditional solutions have significant drawbacks: First, rigid fixed structures cannot buffer the vibration and impact forces generated by road bumps and rapid acceleration / deceleration during transportation. The impact forces are directly transmitted to the tank body, which can easily lead to cracking of tank welds, failure of sealing components, and even the risk of hydrogen leakage. Second, simple supports have poor adaptability. Different specifications of supports need to be customized for hydrogen energy storage tanks of different heights and volumes, resulting in low versatility and increased equipment investment costs. Third, although some solutions add buffer components such as springs, the buffering direction is only one (most of them can only cope with vertical vibrations), and the frictional resistance between the support and the tank is large. It is impossible to disperse multi-directional impacts through flexible displacement, and it is still difficult to ensure the stability of the storage tank.

[0005] Therefore, the present invention provides a safety anti-collision device for transporting hydrogen storage tanks to solve one or more of the above-mentioned problems. Summary of the Invention

A positioning hole is opened in the center of the limiting groove. Four sets of guide mounting grooves are opened at the bottom of the limiting groove. A telescopic rod is fixedly installed in each set of guide mounting grooves. The arc-shaped locking plates are slidably installed in the guide mounting grooves, and the output end of the telescopic rod is fixedly connected to the arc-shaped locking plates.

[0014] Preferably, the telescopic support rod includes a support rod and a support sleeve. The support rod is fixedly connected to the protective base, and the support sleeve is movably fitted onto the outer wall of the support rod. The support rod and the outer wall of the support sleeve are provided with the same pin holes, and the top of the support sleeve is fixedly connected to the top plate.

[0015] Preferably, the gripper assembly includes a main clamping component, which is fixedly connected to the output end of a hydraulic cylinder. One end of a shaped connecting rod is movably connected to the main clamping component, and the other end of the shaped connecting rod is fixedly provided with an arc-shaped clamping plate. A fixed plate is fixedly connected to the shaped connecting rod, and the fixed plate is connected to the main clamping component through a hydraulic cylinder. The fixed end of the hydraulic cylinder is movably connected to the main clamping component, and the output end of the hydraulic cylinder is movably connected to the fixed plate.

[0016] Preferably, on the side of the arc-shaped clamping plate two near the hydrogen storage tank, a set of arc-shaped toothed components one and two sets of arc-shaped toothed components two are installed in sections. The arc-shaped toothed components one is fixedly connected to the arc-shaped clamping plate two, and the arc-shaped toothed components two are fixedly connected to one end of the first connecting rod. The first connecting rod is slidably connected to the arc-shaped clamping plate two. The buffer spring two is sleeved on the outer wall of the first connecting rod, and one end of the buffer spring two is fixedly connected to the arc-shaped clamping plate two, and the other end of the buffer spring two is fixedly connected to the first connecting rod.

[0017] Preferably, the bottom of the top plate is provided with a receiving groove, and a number of buffer springs are provided in the receiving groove.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] The transport base plate is bolted to the transport vehicle compartment, providing a stable load-bearing benchmark for the entire hydrogen storage tank anti-collision device. Subsequently, a ball bearing base plate with several sets of ball bearings is installed between the transport base plate and the protective base, creating a rolling friction fit between the protective base and the transport base plate to allow for flexible sliding within a small range. After the hydrogen storage tank is hoisted to the center of the protective base, the tank is initially radially positioned using the limiting components at the center of the protective base. Then, the lengths of several sets of telescopic support rods surrounding the limiting components are adjusted, causing the top plate to rise and fall synchronously until the pressure head at the bottom of the top plate tightly abuts against the top of the hydrogen storage tank, forming a coordinated fixing effect of "radial constraint + axial compression." When the transport vehicle moves... When encountering bumps or acceleration / deceleration, the vibration impact force is transmitted to the protective base through the transport base plate, ball bearing base plate, and ball bearings. The protective base can slide along the ball bearings within a small range to disperse the impact force. At the same time, the telescopic support rod absorbs vibration energy through slight deformation, avoiding rigid impact damage to the storage tank. This solution achieves a stable assembly of the device and the vehicle through bolted connection of the transport base plate, adapting to different vehicle structures. It also provides flexible buffering through the rolling action of the ball bearings. Furthermore, the combination of limiting components, telescopic support rods, and pressure heads prevents the storage tank from shifting. The telescopic support rods can also be adapted to storage tanks of different heights. The overall structure is simple and easy to operate, balancing safety, versatility, and operational efficiency, while reducing equipment investment and operating costs. Attached Figure Description

They are merely used to distinguish protective components or operations described using the same technical terms, and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Furthermore, the technical solutions and features of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0031] Example 1

[0032] Please see Figures 1-2 The present invention provides a technical means including a transport base plate 1, which is bolted to the transport compartment. A protective base 3 is installed on the top of the transport base plate 1. A limiting component 9 is provided at the center of the protective base 3. Several sets of telescopic support rods 4 are arranged around the limiting component 9 and installed on the transport base plate 1. A top plate 7 is provided on the top of the several sets of telescopic support rods 4. A pressure head 8 is provided at the bottom of the top plate 7.

[0033] The working principle and beneficial effects of the above scheme are as follows: The transport base plate 1 is bolted into the transport compartment, providing a stable bearing benchmark for the entire hydrogen energy storage tank anti-collision device. Subsequently, a ball bearing base plate 2 with several sets of ball bearings 15 is assembled between the transport base plate 1 and the protective base 3, so that the protective base 3 and the transport base plate 1 form a rolling friction fit to have the ability to slide flexibly within a small range. After the hydrogen energy storage tank is hoisted to the center of the protective base 3, the tank is initially radially positioned using the limiting component 9 at the center of the protective base 3. Then, the lengths of several sets of telescopic support rods 4 set around the limiting component 9 are adjusted to drive the top plate 7 at the top to rise and fall synchronously until the pressure head 8 at the bottom of the top plate 7 is tightly abutted against the top of the hydrogen energy storage tank, forming a synergistic fixing effect of "radial constraint + axial compression". When the transport vehicle encounters bumps, acceleration, or deceleration, the vibration impact force is transmitted to the protective base 3 via the transport base plate 1, the ball bearing base plate 2, and the ball bearings 15. The protective base 3 can slide along the ball bearings 15 within a small range to disperse the impact force. At the same time, the telescopic support rod 4 absorbs the vibration energy through slight deformation, avoiding rigid impact damage to the storage tank. This solution achieves a stable assembly between the device and the vehicle body through the bolt connection of the transport base plate 1, adapting to different vehicle body structures. It also provides flexible buffering through the rolling action of the ball bearings 15. Furthermore, the combination of the limiting component 9, the telescopic support rod 4, and the pressure head 8 prevents the storage tank from shifting. The telescopic support rod 4 can also be adapted to storage tanks of different heights. The overall structure is simple and easy to operate, taking into account safety, versatility, and operational efficiency, while reducing equipment investment and operating costs.

[0034] Example 2

[0035] Based on Example 1, please refer to Figures 2-3 A ball bearing base plate 2 is provided between the transport base plate 1 and the protective base 3. Several sets of balls 15 are installed on the ball bearing base plate 2, and the bottom of the protective base 3 is placed on several sets of balls 15.

[0036] Preferably, two sets of limiting brackets 16 are symmetrically installed on the transport base plate 1 by bolts, and the protective base 3 is placed between the two sets of limiting brackets 16. A pressure plate 19 is installed on the side of the limiting bracket 16 near the outer wall of the protective base 3 by a buffer spring 17, and several sets of clamping rods 18 are fixed on the pressure plate 19.

[0037] Preferably, the protective base 3 has several sets of slots 20 corresponding to the locking rods 18 on the side near the limiting bracket 16, and four sets of rope fixing points 21 are provided around the outer wall of the protective base 3.

[0038] The working principle and beneficial effects of the above scheme are as follows: When installing the protective base 3, the two sets of pressure plates 19 are pushed away to compress the buffer spring 17, and the protective base 3 is placed directly on the ball bearing base plate 2. Then, the ball bearing base plate 2 is released, and under the push of the buffer spring 17, the pressure plate 19 moves towards the protective base 3 until the locking rod 18 enters the locking groove 20, thus completing the installation of the protective base 3. The vibration generated during the movement of the transport vehicle will cause the protective base 3 to move slightly on the ball bearing 15, thereby dispersing the vibration force. On this basis, in conjunction with the buffer springs 17 on both sides, the relative stability of the hydrogen energy storage tank can be maintained and the vibration amplitude can be reduced.

[0039] Example 3

[0040] Based on any one of Examples 1-2, please refer to Figure 4 and Figure 8 The limiting component 9 includes four sets of arc-shaped clamping plates 24. The protective base 3 has a limiting groove 22 in the center, and a positioning hole 23 in the center of the limiting groove 22. The bottom of the limiting groove 22 has four sets of guide mounting grooves 26. A telescopic rod 25 is fixedly installed in each set of guide mounting grooves 26. The arc-shaped clamping plates 24 are slidably installed in the guide mounting grooves 26, and the output end of the telescopic rod 25 is fixedly connected to the arc-shaped clamping plates 24.

[0041] Preferably, the bottom of the top plate 7 is provided with a receiving groove 39, and a number of buffer springs 40 are provided in the receiving groove 39. One end of the buffer spring 40 is fixedly connected to the inner wall of the receiving groove 39, and the other end of the buffer spring 40 is fixedly connected to the pressure head 8.

[0042] The working principle and beneficial effects of the above scheme are as follows: When installing the hydrogen energy storage tank, after using tools to hoist the hydrogen energy storage tank into the limiting groove 22 of the protective base 3, the telescopic rod 25 is activated to drive the arc-shaped clamping plate 24 to move towards the outer wall of the hydrogen energy storage tank, thereby initially securing the hydrogen energy storage tank and preventing it from moving during subsequent operations, which greatly improves safety.

[0043] The pressure head 8 is installed at the bottom of the top plate 7 via a buffer spring 40. After the hydrogen energy storage tank is installed, the top plate 7 can be installed on the top of the telescopic support rod 4, so that the pressure head 8 is tightly pressed against the top of the hydrogen energy storage tank, thereby improving the stability of the hydrogen energy storage tank.

[0044] Example 4

[0045] Based on any one of Examples 1-3, please refer to Figure 1 , Figures 5-7The telescopic support rod 4 includes a support rod 27 and a support sleeve 28. The support rod 27 is fixedly connected to the protective base 3. The support sleeve 28 is movably sleeved on the outer wall of the support rod 27. The support rod 27 and the support sleeve 28 have the same pin holes 29 on their outer walls. The top of the support sleeve 28 is fixedly connected to the top plate 7.

[0046] Preferably, the gripper assembly 6 includes a main clamping member 30, which is fixedly connected to the output end of the hydraulic cylinder 5. One end of the irregularly shaped connecting rod 33 is movably connected to the main clamping member 30, and the other end of the irregularly shaped connecting rod 33 is fixedly provided with an arc-shaped clamping plate 34. A fixing plate 32 is fixedly connected to the irregularly shaped connecting rod 33. The fixing plate 32 and the main clamping member 30 are connected through a hydraulic cylinder 31. The fixed end of the hydraulic cylinder 31 is movably connected to the main clamping member 30, and the output end of the hydraulic cylinder 31 is movably connected to the fixing plate 32.

[0047] Preferably, on the side of the arc-shaped clamping plate 34 near the hydrogen storage tank, a set of arc-shaped toothed components 35 and two sets of arc-shaped toothed components 36 are installed in sections. The arc-shaped toothed components 35 are fixedly connected to the arc-shaped clamping plate 34, and the arc-shaped toothed components 36 are fixedly connected to one end of the first connecting rod 37. The first connecting rod 37 is slidably connected to the arc-shaped clamping plate 34. The buffer spring 38 is sleeved on the outer wall of the first connecting rod 37, and one end of the buffer spring 38 is fixedly connected to the arc-shaped clamping plate 34, while the other end of the buffer spring 38 is fixedly connected to the first connecting rod 37.

[0048] The working principle and beneficial effects of the above scheme are as follows: The movement distance of the support sleeve 28 on the support rod 27 can be adjusted according to the height of the hydrogen energy storage tank. When the height of the hydrogen energy storage tank is met, the support rod 27 and the support sleeve 28 are locked with pins. Then, the hydraulic cylinder 5 is started to push the main clamp 30 to abut against the outer wall of the hydrogen energy storage tank and then stops. The hydraulic cylinder 31 is started again to drive the irregular connecting rod 33 to rotate through the fixed plate 32 until the arc-shaped clamp 34 abuts against the outer wall of the hydrogen energy storage tank. The arc-shaped toothed parts 35 and 36 on the arc-shaped clamp 34 can increase the friction between the arc-shaped clamp 34 and the outer wall of the hydrogen energy storage tank, thereby greatly improving the locking force on the hydrogen energy storage tank.

[0049] In the event of sudden braking or accidental collision of the transport vehicle, the gripper assembly 6 can prevent the hydrogen storage tank from overturning, and the "cage-like" net formed by several sets of telescopic support rods 4 can protect the hydrogen storage tank.

[0050] Example 5

[0051] Based on any one of Examples 1-4, please refer to Figure 1 and Figure 3The mounting bracket 10 and the rope fixing bracket 14 are installed in the transport vehicle by bolts. The threaded rod 12 is threadedly connected to the mounting bracket 10, and a ring 11 is installed at the bottom of the threaded rod 12. One end of the limiting pull rope 13 is connected to the rope fixing point 21, and the other end of the limiting pull rope 13 passes through the mounting bracket 10 and the ring 11 and is connected to the rope fixing bracket 14.

[0052] The working principle and beneficial effects of the above scheme are as follows: After the hydrogen storage tank is installed through the above embodiment, four sets of rings 11 and rope fixing frames 14 are installed into the transport vehicle and set around the protective base 3 by bolts. Then, one end of the limiting pull rope 13 is connected to the rope fixing point 21, and the other end passes through the mounting bracket 10 and the rings 11 and is connected to the rope fixing frame 14. Then, the threaded rod 12 is rotated, so that the threaded rod 12 drives the rings 11 to rise / fall, thereby adjusting the tension of the limiting pull rope 13, and thus adjusting the traction force of the limiting pull rope 13 on the protective base 3. It is simple and convenient.
