Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen storage, in particular to a storage device for preventing hydrogen from evaporating. Background Art

[0002] Hydrogen is a colorless, tasteless, odorless gas. It is an extremely light gas at room temperature with a very low density. Due to its light weight and abundance, hydrogen is widely used in various applications. Due to its extremely small molecular size and high permeability, hydrogen can pass through some common storage container materials, which eventually causes hydrogen to evaporate during storage. Only by lowering the ambient temperature of hydrogen storage to a certain range can hydrogen evaporation be effectively avoided.

[0003] When hydrogen is stored in a liquid or high-pressure state, if the surface temperature of the hydrogen storage tank is low, moisture in the surrounding air may condense into water droplets, forming defrost on the outer wall of the hydrogen storage tank. The existing hydrogen storage tank lacks an outer wall cleaning device, which causes the outer wall of the hydrogen storage tank to be corroded and damaged by defrosting, further reducing the service life of the hydrogen storage tank. In addition, the current storage of hydrogen is generally to pass the hydrogen into a cooling device for cooling, and then introduce the cooled hydrogen into the hydrogen storage tank for storage. After a long period of storage, since the ambient temperature outside the hydrogen storage tank is always lower than the temperature inside the hydrogen storage tank, this will cause the temperature of the hydrogen inside the hydrogen storage tank to rise, and further cause the hydrogen to evaporate. Therefore, it is necessary to provide a storage device to prevent hydrogen evaporation to solve the above technical problems. Utility Model Content

[0004] The purpose of the utility model is to provide a storage device for preventing hydrogen from evaporating, so as to solve the above-mentioned shortcomings in the prior art.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a storage device for preventing hydrogen evaporation, comprising: an outer shell, a hydrogen storage tank is installed inside the outer shell, and four evenly distributed fixing rods are installed at one end of the hydrogen storage tank, a first motor is installed on the outer wall of the upper end of the outer shell, a second motor is installed on the right inner wall of the outer shell, the left inner wall of the outer shell is connected to one end of the hydrogen storage tank through four fixing rods, an air duct is connected to the left side of the hydrogen storage tank, a cooling box is installed on the left outer wall of the outer shell, and the right side of the cooling box is connected to the air duct, an air intake pipe is connected to the upper end of the cooling box, a moving ring is provided on the outside of the hydrogen storage tank, and a scraper is fixedly connected to the inner outer wall of the moving ring, and first connecting blocks are evenly installed on the surrounding outer walls of the moving ring and a second connecting block, threaded rods are rotatably installed between the inner walls of the left and right sides of the outer shell, and the two threaded rods are connected to the second connecting block by threads, the left side of the threaded rod is fixedly connected to the first bevel gear, and a rotating rod is rotatably installed inside the left side of the outer shell, and the upper end of the rotating rod is connected to the rotating shaft of the first motor, and two symmetrically distributed second bevel gears are installed on the rotating rod, and the first bevel gear is meshed with the second bevel gear; a rotating block is slidably installed inside the movable ring, and a cooling device is fixedly connected to the right outer wall of the rotating block, a connecting sleeve rod is fixedly connected to the right side of the cooling device, and a connecting plug rod is movably inserted on the right side of the connecting sleeve rod, a connecting rod is fixedly connected to the connecting plug rod, and the other end of the connecting rod is connected to the rotating shaft of the second motor.

[0006] Preferably, the two first connecting blocks and the second connecting blocks are spaced apart on the outer wall of the movable ring, and an auxiliary rod is slidably inserted into the interior of the first connecting block, and a threaded rod is inserted into the internal thread of the second connecting block, so that the movable ring can drive the scraper to move laterally on the auxiliary rod and the threaded rod, and further ensure that the scraper can clean up all the defrost on the outer wall of the hydrogen storage tank.

[0007] Preferably, a circular groove is provided inside the movable ring, and a rotating block is slidably installed inside the groove. The cooling device can rotate in the circular groove inside the movable ring through the rotating block and the roller, further ensuring the normal operation of the cooling device.

[0008] Preferably, both of the second connecting blocks are fixedly connected with sliders, and sliding grooves are provided on the inner walls of the upper and lower ends of the outer shell, and the two sliders are slidably installed in the sliding grooves respectively. When the moving ring moves laterally, the sliders also start to slide in the sliding grooves on the outer walls of the upper and lower ends of the outer shell, further ensuring that the moving ring can move normally and ensuring the normal operation of the entire device.

[0009] Preferably, a circular groove is provided on the right inner wall of the outer shell, and the right side of the connecting rod is slidably installed inside the circular groove. Under the action of the second motor, the connecting rod begins to move in the circular groove on the right inner wall of the outer shell, further enabling the cooling equipment to smoothly rotate around the outer wall of the hydrogen storage tank, thereby ensuring the normal operation of the cooling device.

[0010] Preferably, two symmetrically distributed auxiliary rods are rotatably installed on the inner walls of the left and right sides of the outer shell, and the two auxiliary rods are rotatably inserted inside the first connecting block.

[0011] Preferably, a roller is fixedly connected to the left outer wall of the rotating block. The installation of the roller enables the rotating block to move more smoothly in the circular slide groove inside the moving ring, further ensuring the normal operation of the cooling device.

[0012] In the above technical solution, the utility model provides a storage device for preventing hydrogen evaporation, which has the following beneficial effects:

[0013] The device is provided with a moving ring on the outer sleeve of the hydrogen storage tank, and a scraper is installed on the inner wall of the moving ring. When defrosting occurs on the outer surface of the hydrogen storage tank, the first motor can be started, and the first motor drives the rotating rod to start rotating. Under the action of the first bevel gear and the second bevel gear, the threaded rod starts to rotate. Because the second connecting block on the moving ring is threadedly connected to the threaded rod, the moving ring starts to move on the outer wall of the hydrogen storage tank, and the defrosting on the outer wall of the hydrogen storage tank can be further cleaned, effectively avoiding the outer wall of the hydrogen storage tank from being corroded and damaged by defrosting. In addition, after the hydrogen storage tank has been used for a period of time, the second motor can be started, and the connecting rod can be driven to start rotating in the circular slide groove on the right side of the outer shell under the action of the connecting rod. Because the connecting rod is connected to the cooling device through the connecting sleeve rod, and the cooling device is slidably installed on the moving ring through the rotating block, the cooling device starts to rotate around the outer wall of the hydrogen storage tank, and the cooling device also starts to move under the rotation of the threaded rod, so that the cooling device can evenly cool the outer wall of the hydrogen storage tank, further avoiding the evaporation of hydrogen inside the hydrogen storage tank due to excessive temperature.

[0026] A rotating block 18 is slidably installed inside the movable ring 7, and a cooling device 20 is fixedly connected to the right outer wall of the rotating block 18 (this is the prior art, the specific model is selected according to actual needs, and it is not described in detail here), a connecting sleeve rod 21 is fixedly connected to the right side of the cooling device 20, and a connecting plug rod 22 is movably inserted on the right side of the connecting sleeve rod 21, a connecting rod 23 is fixedly connected to the connecting plug rod 22, and the other end of the connecting rod 23 is connected to the rotating shaft of the second motor 24.

[0027] Specifically, the two first connecting blocks 9 and the second connecting blocks 10 are spaced apart on the outer wall of the movable ring 7. An auxiliary rod 11 is slidably inserted into the interior of the first connecting block 9, and a threaded rod 12 is threadedly inserted into the interior of the second connecting block 10, so that the movable ring 7 can drive the scraper 8 to move laterally on the auxiliary rod 11 and the threaded rod 12, and further ensure that the scraper 8 can clean up all the defrost on the outer wall of the hydrogen storage tank 2.

[0028] Specifically, a circular groove is opened inside the movable ring 7, and the rotating block 18 is slidably installed inside the groove. The cooling device 20 can rotate in the circular groove inside the movable ring 7 through the rotating block 18 and the roller 19, further ensuring the normal operation of the cooling device.

[0029] Specifically, the two second connecting blocks 10 are fixedly connected with sliders 13, and the inner walls of the upper and lower ends of the outer shell 1 are provided with sliding grooves, and the two sliders 13 are slidably installed inside the sliding grooves respectively. When the movable ring 7 moves laterally, the sliders 13 also start to slide in the sliding grooves on the outer walls of the upper and lower ends of the outer shell 1, further ensuring that the movable ring 7 can move normally and ensuring the normal operation of the entire device.

[0030] Specifically, a circular groove is opened on the right inner wall of the outer shell 1, and the right side of the connecting rod 22 is slidably installed inside the circular groove. Under the action of the second motor 24, the connecting rod 22 begins to move in the circular groove on the right inner wall of the outer shell 1, further enabling the cooling device 20 to smoothly rotate around the outer wall of the hydrogen storage tank 2, thereby ensuring the normal operation of the cooling device.

[0031] Specifically, two symmetrically distributed auxiliary rods 11 are rotatably installed on the inner walls on the left and right sides of the outer shell 1, and the two auxiliary rods 11 are rotatably inserted inside the first connecting block 9.

[0032] Specifically, a roller 19 is fixedly connected to the left outer wall of the rotating block 18. The installation of the roller 19 enables the rotating block 18 to move more smoothly in the circular slide groove inside the moving ring 7, further ensuring the normal operation of the cooling device.

[0033] Working principle: When defrosting occurs on the outer surface of the hydrogen storage tank 2, the first motor 17 can be started, and the first motor 17 drives the rotating rod 16 to start rotating. Under the action of the first bevel gear 14 and the second bevel gear 15, the threaded rod 12 starts to rotate. Because the second connecting block 10 on the moving ring 7 is threadedly connected to the threaded rod 12, the moving ring 7 starts to move on the outer wall of the hydrogen storage tank 2, and further the defrosting on the outer wall of the hydrogen storage tank 2 can be cleaned. After the hydrogen storage tank 2 has been used for a period of time, the second motor 24 can be started, and the connecting rod 22 can start to rotate under the action of the connecting rod 23. The outer shell 1 rotates in the circular groove on the right side of the outer shell 1. Because the connecting rod 22 is connected to the cooling device 20 through the connecting sleeve rod 21, and the cooling device 20 is slidably installed on the movable ring 7 through the rotating block 18, the cooling device 20 begins to rotate around the outer wall of the hydrogen storage tank 2. At the same time, the cooling device 20 also starts to move under the rotation of the threaded rod 12. In this way, the cooling device 20 can evenly cool the outer wall of the hydrogen storage tank 2, further avoiding the evaporation of hydrogen inside the hydrogen storage tank 2 due to excessive temperature. This is the entire working process of a storage device for preventing hydrogen evaporation.
