Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen storage, and specifically relates to a hydrogen storage device. Background Art

[0002] For high-pressure gaseous hydrogen storage, the storage method is to compress hydrogen into a high-pressure-resistant container by high pressure. This hydrogen storage method is the most commonly used and relatively mature technology at present. Existing high-pressure hydrogen storage tanks usually have a structure of a metal inner lining with fibers and a protective layer wound outside, and anti-static operations can be carried out.

[0003] According to an explosion-proof storage device for hydrogen transportation (publication number: CN217402292U) announced, in the above application, the hydrogen storage tank is provided with an inner tank, an explosion-proof interlayer, an outer tank, and a hydrogen inlet and outlet. A fiber winding layer is coated around the inner tank. The explosion-proof interlayer is between the fiber winding layer and the outer tank, and the explosion-proof interlayer is filled with explosion-proof materials. Valves are provided on the hydrogen inlet and outlet, and a protective box is covered outside the hydrogen inlet and outlet. An openable and closable cover is provided on the protective box in the direction facing the pipe orifice of the hydrogen inlet and outlet.

[0004] However, in the actual use process of the above device, although the valve can be opened and closed through the openable and closable cover, since there is no restriction on the cover, it is easy for the cover to be opened in the case of being impacted by the outside or being accidentally touched, and then the valve is damaged, thus affecting the safety of hydrogen storage. In view of this, we propose a hydrogen storage device. Content of the Utility Model

[0005] The purpose of the utility model is to provide a hydrogen storage device to solve the problems put forward in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A hydrogen storage device includes a multi-layer tank body. A valve head is arranged at the upper end of the multi-layer tank body. A rotary knob is rotatably installed on the outer wall of the valve head. An air vent socket is arranged on the outer wall of the valve head. A protective component is arranged on the outer wall of the multi-layer tank body. The protective component includes a rotating groove which is opened at the upper end of the multi-layer tank body. A rotating sheath is rotatably installed on the inner wall of the rotating groove. A fixed arc pile is fixedly connected to the upper end of the valve head. A resilient telescopic plate is fixedly connected to the outer wall of the fixed arc pile. A protective arc plate is fixedly connected to the end of the resilient telescopic plate;

[0007] Slot hole 1, the slot hole 1 is opened on the outer wall of the rotating sheath. An insertion plate is fixedly connected to the outer wall of the protective arc plate. A rubber sleeve is fixedly connected to the end of the insertion plate. A limiting groove 1 is opened on the inner wall of the rotating sheath.

[0008] Preferably, a buffer assembly is provided on the outer wall of the rotating sheath. The buffer assembly includes a buffer rubber pad which is fixedly connected to the top end of the rotating sheath. A limiting hole is formed in the top end of the rotating sheath. A limiting plate is fixedly connected to the bottom end of the buffer rubber pad. A second limiting groove is formed in the outer wall of the elastic telescopic plate.

[0009] Preferably, the protective arc plate is adapted to the first slot hole, so that the protective arc plate can completely cover the first slot hole, and the objects inside the rotating sheath can be protected.

[0010] Preferably, two groups of the first slot holes are provided, and the two groups of the first slot holes are arranged on both sides in a mirror image with respect to the center of the rotating sheath, so that corresponding operations can be performed on the ventilation socket and the rotary knob through the two groups of the first slot holes.

[0011] Preferably, the limiting plate is adapted to the limiting hole, so that when the limiting plate is subjected to force and extrusion, it can only move vertically downward.

[0012] Preferably, the outer surface of the limiting plate is movably connected to the inner surface of the second limiting groove, so that the limiting plate can be inserted into the second limiting groove, and the elastic telescopic plate cannot perform a contraction operation.

[0013] Compared with the prior art, the present utility model provides a hydrogen storage device, which has the following beneficial effects:

[0014] 1. After the hydrogen storage device stores hydrogen in the daily multi-layer tank body, if the tank body is tilted, rolled, collided, etc., the valve head will be protected by the rotating sheath after contact. By setting the rubber sleeve and the elastic telescopic plate, the insertion plate can stably limit the rotating sheath. And by setting the insertion plates on both sides of the inner wall of the rotating sheath, when the top end of the tank body rolls or is touched, after one side of the insertion plate performs a buffer and backward movement operation, the rotating sheath will still be restricted by the insertion plate on the opposite side. Only after simultaneously pinching the protective arc plates on both sides and then rotating the rotating sheath counterclockwise by 90 degrees can the first slot hole be opened. At this time, corresponding operations can be performed on the ventilation socket and the rotary knob, finally solving the problem that the cover body is not restricted and is easily opened under external impact or accidental touch.

[0015] 2. In the hydrogen storage device, through the buffer rubber pad at the top end of the rotating sheath, the top end of the tank body can perform a primary buffer operation when it is collided and touched. And when the buffer rubber pad is deformed by force, it will squeeze the limiting plate, so that the limiting plate moves vertically under the force and extrusion, and finally the limiting plate can be inserted into the second limiting groove, and the elastic telescopic plate cannot perform a contraction operation, realizing the prevention of the protective arc plate from being accidentally touched and displaced, thereby better increasing the overall practicability.

[0024] In an embodiment of the present utility model, a buffer assembly 7 is provided on the outer wall of the rotating sheath 602. The buffer assembly 7 includes a buffer rubber pad 701. The buffer rubber pad 701 is fixedly connected to the top end of the rotating sheath 602. A limiting hole 702 is opened at the top end of the rotating sheath 602. A limiting plate 703 is fixedly connected to the bottom end of the buffer rubber pad 701. A second limiting groove 704 is opened on the outer wall of the elastic telescopic plate 604. The protective arc plate 605 is adapted to the first slot hole 606, so that the protective arc plate 605 can completely cover the first slot hole 606, and the objects inside the rotating sheath 602 can be protected.

[0025] And the number of the first slot holes 606 is two groups, and the two groups of the first slot holes 606 are symmetrically arranged on both sides with the center of the rotating sheath 602 as the mirror image, so that the ventilation socket 5 and the rotary knob 3 can be correspondingly operated through the two groups of the first slot holes 606. The limiting plate 703 is adapted to the limiting hole 702, so that when the limiting plate 703 is subjected to force extrusion, it can only move vertically downward.

And when the buffer rubber pad 701 is deformed by force, it will squeeze the limiting plate 703, and then the limiting plate 703 will move vertically under the force extrusion, and finally the limiting plate 703 can be inserted into the second limiting groove 704, so that the elastic telescopic plate 604 cannot perform the contraction operation, realizing the prevention of the displacement of the protective arc plate 605 being accidentally touched, and further better increasing the overall practicability.

[0028] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made thereto, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit and idea of the present utility model are within the protection scope of the present utility model.
