Description

Technical Field

[0001] The utility model relates to the technical field of storage devices, and in particular to a storage device for liquefied hydrogen. Background Art

[0002] Liquefied hydrogen is a liquid obtained by cooling hydrogen to -253°C. Compared with high-pressure gaseous hydrogen, it has a higher energy density per unit mass. With the development of clean energy, the demand for liquefied hydrogen is also increasing. It can be used directly as an energy source, or liquefied hydrogen can be converted into high-pressure gaseous hydrogen for reuse. There are also high requirements for the storage of liquefied hydrogen.

[0003] When storing liquefied hydrogen, it is usually placed in a tank with multiple layers of protection. The liquid nitrogen inside the tank is used as a low-temperature insulation medium, and an outer layer of insulation material is added to the outside to meet the storage conditions of liquefied hydrogen. Due to volume limitations, smaller storage devices cannot effectively prevent the hydrogen inside the liquefied hydrogen from gasifying when storing liquefied hydrogen, resulting in the storage device usually being filled with hydrogen. If the storage device shakes significantly during the transportation of liquefied hydrogen, it may cause the storage device to explode, resulting in an accident, leading to the problem of low safety of the storage device. Utility Model Content

If the storage device shakes significantly during the transportation of liquefied hydrogen, it may cause the storage device to explode, resulting in an accident, and the storage device has low safety.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a storage device for liquefied hydrogen, comprising a tank body, an inlet pipe is provided at one end of the tank body, a sealing cover is provided on the outer surface of the inlet pipe, a stabilizing device is provided on the outer surface of the tank body, the stabilizing device comprises a groove ring, the inner wall of the groove ring is fixedly connected to the outer surface of the tank body, the bottom end of the groove ring is fixedly connected to a base, groove plates are fixedly connected on both sides of the groove ring, a rectangular groove is provided on the outer surface of the groove plate, a sliding plate is slidably connected to the inner wall of the groove plate, one end of the sliding plate is fixedly connected to the rectangular plate, a screw is fixedly connected to one side of the sliding plate, the outer surface of the screw slides on the inner wall of the rectangular groove, the outer surface of the screw is slidably connected to a U-shaped block, and the outer surface of the screw is threadedly connected to a threaded ring.

[0006] The effect achieved by the above components is: by setting a rectangular plate, the storage device is transported. When the storage device is placed on the transportation equipment, the base can be placed on the surface of the transportation equipment, and the two sliding plates on both sides of the groove ring are pushed to slide on the inner wall of the groove plate, so that the rectangular plate at one end of the sliding plate is pressed against the wall of the transportation equipment, and then the threaded rings on the outer surface of the screw at one end of the two sliding plates are rotated respectively, so that the movement of the threaded rings on the outer surface of the screw pushes the U-shaped block to move, and presses one side of the U-shaped block against the outer surface of the groove plate to fix the position of the sliding plate.

[0007] Preferably, one end of the screw rod away from the sliding plate is fixedly connected to a stopper, and the length of the stopper is greater than the diameter of the screw rod.

[0008] The effect achieved by the above components is: by setting the stopper, the movement range of the thread ring on the outer surface of the screw can be limited, preventing the thread ring from falling off the screw surface when it moves away from the screw surface.

[0009] Preferably, a plurality of protrusions are fixedly connected to the outer surface of the threaded ring, and the protrusions are distributed in a circular pattern on the outer surface of the threaded ring.

[0010] The effect achieved by the above components is that gripping the bumps on the outer surface of the threaded ring can increase the friction between the hand and the outer surface of the threaded ring, making it more convenient to rotate the threaded ring and less likely to cause hand slippage.

[0011] Preferably, one end of the sliding plate away from the screw rod is fixedly connected to a T-shaped block, and the outer surface of the T-shaped block slides on the inner wall of the rectangular groove.

[0012] The effect achieved by the above components is that when the sliding plate slides on the inner wall of the groove plate, the outer surface of the T-shaped block will slide on the inner wall of the rectangular groove. The T-shaped block can further limit the angle between the two ends of the sliding plate and the groove plate, thereby avoiding the angle of the sliding plate from deflecting as much as possible.

[0013] Preferably, two inclined plates are fixedly connected to the outer surface of the groove ring, and one end of the two inclined plates away from the groove ring is fixedly connected to the top of the groove plate.

[0014] The effects achieved by the above components are: by arranging the inclined plate, the connection between the groove ring and the groove plate can be reinforced, thereby increasing the structural stability of the groove ring and the groove plate.

[0015] Preferably, a plurality of convex strips are fixedly connected to the bottom end of the base, and the convex strips are made of rubber material.

[0016] The effect achieved by the above components is that by providing the rubber convex strips, the side of the bottom end of the base provided with the convex strips is more stable and less likely to slide when in contact with the surface of the transportation equipment.

[0017] Preferably, an auxiliary device is provided at the top end of the groove ring, and the auxiliary device includes two groove blocks, and the outer surfaces of the two groove blocks are provided with clamping grooves.

[0018] The effect achieved by the above components is that when transporting the tank body, the transporting tool or lifting tool can be clamped inside the clamping groove on the outer surface of the tank block, which makes it more convenient to lift the tank body and move it without shaking.

[0019] Preferably, the inner wall of the slot block is threadedly connected with a bolt, the bottom end of the bolt is rotatably connected to a rectangular block, and both ends of the rectangular block slide on the inner wall of the slot.

[0020] The effect achieved by the above components is: rotating the bolt to move the bolt on the inner wall of the slot block can drive the rectangular block to slide on the inner wall of the slot, adjust the internal size of the slot, and better fix the position of the handling tool or lifting tool stuck inside the slot.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are:

[0022] In the utility model, by providing a stabilizing device, when the tank body is placed on the transport equipment, the two sliding plates can be pushed to move one end of the two rectangular plates against the wall of the transport equipment and the position of the sliding plates can be fixed, thereby limiting the position of the tank body on the transport equipment and avoiding as much as possible the large shaking of the tank body during transportation that may cause hydrogen explosion inside the tank body.

By providing the rectangular plate 29, the storage device can be transported and placed The two sliding plates 25 can be pushed to move one end of the two rectangular plates 29 against the wall of the transport equipment and fix the position of the sliding plates 25, thereby limiting the position of the tank body 1 on the transport equipment and avoiding as much as possible the large shaking of the tank body 1 during transportation, which may cause the hydrogen inside the tank body 1 to explode.

[0030] Reference Figure 1-5As shown, in this embodiment: the end of the screw 26 away from the sliding plate 25 is fixedly connected to a stopper 210, and the length of the stopper 210 is greater than the diameter of the screw 26.
