[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example: Figure 1-4As shown, the utility model provides an anti-collision device for a liquid hydrogen storage tank, comprising a box body 1, two fixed frames 13 are fixedly installed on opposite sides of the inner wall of the box body 1, and a fixed rod 14 is fixedly installed on opposite sides of the inner wall of the fixed frame 13, and a plurality of first snap rings 15 and a second snap ring 16 are movablely sleeved on the outer side of the fixed rod 14, and a first spring 17 is fixedly installed on the side of the first snap ring 15 and the second snap ring 16 away from each other, and a stabilizing block 18 is fixedly installed on the other end of the first spring 17, and the stabilizing block 18 is fixedly connected to the fixed frame 13, and a plurality of groups of symmetrically distributed support plates 19 are fixedly installed on the side of the fixed frame 13 close to the first snap ring 15, and an insertion rod 191 is fixedly installed on the side of the first snap ring 15 and the second snap ring 16 away from each other, and the insertion rod 191 passes through the support plate 19, and a collar 192 is fixedly sleeved on the outer side of the insertion rod 191, and a second spring 193 is fixedly installed on the side of the collar 19 close to the support plate 19, and the other side of the second spring 193 is fixedly connected to the support plate 19.

[0018] A symmetrically distributed support frame 2 is fixedly installed on one side of the box body 1, and evenly distributed mounting rings 21 are fixedly installed on the inner wall of the support frame 2. Both ends of the mounting ring 21 are provided with symmetrically distributed fixing holes 7. By setting the fixing holes 7, the mounting ring 21 can be disassembled and replaced conveniently; the internal rotation of the mounting ring 21 is penetrated by a rotating rod 22, and the outer fixed sleeve of the rotating rod 22 is provided with a protective sleeve 23.

[0019] A silicone pad 3 is fixedly mounted on the inner walls of the first clamping ring 15 and the second clamping ring 16 . The silicone pad 3 can reduce the wear of the hydrogen storage tank caused by the first clamping ring 15 and the second clamping ring 16 .

[0020] Movable plates 4 are provided on both sides of the box body 1 away from the support frame 2, and clamping rods 41 are fixedly installed at the four corners of the movable plate 4 close to the box body 1. Evenly distributed clamping grooves 42 are opened on both sides of the box body 1 close to the movable plate 4, and the clamping rods 41 are movably clamped in the clamping grooves 42. A sponge block 43 is fixedly connected between the movable plate 4 and the box body 1. When an object collides with the movable plate 4, the movable plate 4 drives the clamping rod 41 to move into the clamping groove 42, so that the movable plate 4 squeezes the sponge block 43, so that the sponge block 43 can absorb and disperse the impact force, thereby reducing the impact on the box body 1.

[0021] The outer side of the card rod 41 is fixedly installed with symmetrically distributed limit blocks 5, and the top and bottom ends of the card slot 42 are provided with limit slots 51. The limit blocks 5 are movably arranged in the limit slots 51. By setting the limit blocks 5 and the limit slots 51, the card rod 41 is prevented from falling off from the card slot 42.

[0022] Two groups of symmetrically distributed third springs 6 are fixedly installed on both sides of the box body 1 close to the movable plate 4, and a transverse plate 61 is fixedly installed on the side of each group of third springs 6 away from the box body 1. By setting the third springs 6 and the transverse plate 61, the rebound speed of the sponge block 43 can be accelerated, and the third springs 6 can further absorb the impact force on the movable plate 4.

[0023] Working principle: During actual use, the hydrogen storage tank is passed through the first clamping ring 15 and the second clamping ring 16. When the box body 1 is hit, the outer side of the hydrogen storage tank shakes, driving the first clamping ring 15 or the second clamping ring 16 to move toward the support plate 19. At this time, the support plate 19 drives the collar 192 to move, so that the collar 192 squeezes the second spring 193, and the first clamping ring 15 or the second clamping ring 16 squeezes the first spring 17, so that the first spring 17 and the second spring 193 absorb part of the impact force. When the external force disappears, the first spring 17 and the second spring 193 return to their original state and release the absorbed energy, so that the hydrogen storage tank releases the impact force while shaking, reducing the damage; when an object hits the protective cover 23 from the side, the protective cover 23 and the rotating rod 22 rotate, so that the impact force can be converted into energy for the rotation of the protective cover 23, reducing the impact on the box body 1, and preventing the object from directly hitting the box body 1.

[0024] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
