Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen storage containers, and particularly to a hydrogen filling device for a hydrogen storage container. Background Art

[0002] In terms of types, hydrogen storage containers are divided into hydrogen storage spheres, hydrogen storage cylinders, and liquid hydrogen storage tanks used in special scenarios. Based on the working principle of liquid hydrogen storage and gaseous hydrogen filling, the main equipment in a liquid hydrogen station includes liquid hydrogen storage containers, high-pressure liquid hydrogen pumps, high-pressure vaporizers (or vaporizers and compressor units), hydrogen storage pressure vessels, pipelines, valves, etc., to achieve the functions of low-pressure storage of liquid hydrogen and high-pressure hydrogen filling in the station.

[0003] At present, when filling hydrogen with the existing hydrogen filling device, after connecting the hydrogen storage container to the hydrogen filling machine, the hydrogen filling equipment is started, and hydrogen enters the hydrogen storage container through the pipeline. During the hydrogen filling process, it is necessary to closely monitor the pressure and temperature changes of the container to ensure that they are within the safe range. Generally speaking, the hydrogen filling speed should not be too fast to avoid excessive temperature rise or pressure fluctuation in the container. Hydrogen filling will generate temperature rise due to the throttling effect, increasing the danger during the hydrogen filling process.

[0033] (III) Beneficial effects

[0034] Compared with the prior art, the present invention provides a hydrogenation device for a hydrogen storage container, which has the following beneficial effects:

[0035] 1. In the present invention, through the lifting of the opening and closing plate, the buffer chamber and the hydrogenation chamber can be opened and closed. By opening the two opening and closing plates in sequence, first the hydrogen storage container enters the buffer chamber. At this time, the hydrogenation chamber is in a closed state. The hydrogen is introduced into the interior of the hydrogenation chamber by opening the gas supply pipe through the valve, and the vacuum pump sucks air into the buffer chamber. The hydrogen in the hydrogenation chamber is introduced into the interior of the buffer chamber by opening the connecting pipe through the valve, so that the buffer chamber and the hydrogenation chamber are filled with hydrogen, and the interior of the hydrogenation chamber is in a low-temperature environment, reducing the temperature rise caused by the throttling effect during hydrogenation, thereby reducing the risk of hydrogenation. Then, the opening and closing plate between the buffer chamber and the hydrogenation chamber is opened, so that the hydrogen storage container moves to the connecting pipe, and the connecting pipe and the hydrogen storage container are connected. The compressor compresses the hydrogen and adds the hydrogen into the interior of the hydrogen storage container through the connecting pipe.

[0036] 2. In the present invention, the connecting pipe and the air inlet of the hydrogen storage container can be manually connected through the operation glove, and the connecting pipe and the air inlet are sealed by the sealing shell, reducing the leakage during hydrogenation. At the same time, the sealing shell limits the air inlet of the hydrogen storage container, making it correspond to the connecting pipe. At the same time, the sealing shell limits the limiting ring to prevent the connecting pipe from falling off from the air inlet of the hydrogen storage container. A pressure sensor is installed inside the sealing shell, which can sense in time when hydrogenation leaks and control the stop of the hydrogenation process.

[0037] 3. In the present invention, the hydrogen storage container is placed on the moving seat, and the hydrogen storage container is limited by the magic tape. The driving shaft drives the walking rod to rotate, and the walking rod contacts the inner bottom wall of the hydrogenation tank, pushing the moving seat and the hydrogen storage container to move inside the hydrogenation tank.

[0038] 4. Therefore, compared with the hydrogenation device in the prior art, in the present invention, hydrogen is transported into the interior of the hydrogenation chamber through the air supply pipe and the connecting pipe, hydrogen is transported into the interior of the buffer chamber through the communication pipe, and the excess air in the buffer chamber is pumped out by the vacuum pump. The hydrogen makes the interior of the hydrogenation chamber in a low-temperature environment, reducing the temperature rise during the hydrogenation process. Through the lifting of the two opening and closing plates, the hydrogen storage container first enters the buffer chamber, and then the buffer chamber is filled with hydrogen, ensuring that when hydrogen leakage occurs in the hydrogenation chamber, the hydrogen leakage is inside the hydrogenation chamber. The hydrogen in the buffer chamber and the hydrogenation chamber can be recovered. The connecting pipe and the air inlet of the hydrogen storage container are sealed by the sealing shell, and at the same time, the sealing shell limits the position of the limiting ring and the connecting pipe, preventing the connecting pipe from falling off the hydrogen storage container, reducing the temperature rise and leakage during the hydrogenation process, and ensuring the safety during the hydrogenation process.

[0060] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0061] Please refer to Figures 1 to 11 , a hydrogenation device for a hydrogen storage container, including a compressor 1, further including a hydrogenation tank 2, a moving mechanism, a conveying component and a cooling component. Compared with the hydrogenation devices in the prior art, the present invention transports hydrogen into the interior of the hydrogenation chamber through the gas supply pipe 601 and the connecting pipe 501, transports hydrogen into the interior of the buffer chamber through the connecting pipe 602, and extracts the excess air in the buffer chamber through the vacuum pump 603. The hydrogen makes the interior of the hydrogenation chamber in a low-temperature environment, reducing the temperature rise during the hydrogenation process. Through the lifting of the two opening and closing plates 101, the hydrogen storage container first enters the buffer chamber, and then the buffer chamber is filled with hydrogen, ensuring that while the hydrogenation chamber is in operation, when hydrogen leakage occurs, the hydrogen leakage is inside the hydrogenation chamber, and the hydrogen in the buffer chamber and the hydrogenation chamber can be recovered. The sealing shell 701 seals the connecting pipe 501 and the air inlet of the hydrogen storage container, and at the same time, the sealing shell 701 positions the limiting ring 702 and the connecting pipe 501 to prevent the connecting pipe 501 from falling off the hydrogen storage container, reducing the temperature rise and leakage during the hydrogenation process and ensuring the safety during the hydrogenation process.

[0062] The hydrogenation tank 2 is provided with a hydrogenation chamber and a buffer chamber. An opening and closing assembly is arranged between the hydrogenation chamber and the buffer chamber and between the buffer chamber and the outside. The opening and closing assembly includes an opening and closing plate 101. The opening and closing plate 101 is arranged on the hydrogenation tank 2 in a liftable manner. The opening and closing plate 101 and the hydrogenation chamber are in sealed sliding fit. Two first electric cylinders 102 are installed on the hydrogenation tank 2. The first electric cylinders 102 correspond to the opening and closing plate 101 one by one. The opening and closing plate 101 is fixedly connected to the output end of the first electric cylinder 102. The opening and closing plate 101 can be driven to lift by the first electric cylinder 102 to open or close the buffer chamber or the hydrogenation chamber. The hydrogen storage container first enters the inside of the buffer chamber. After adjusting the gas environment in the buffer chamber, the hydrogen storage container is then made to enter the hydrogenation chamber to ensure the hydrogen environment in the hydrogenation chamber and cool the hydrogen storage container during the hydrogenation process.

[0063] The moving mechanism is used to move the hydrogen storage container. The moving mechanism includes a limiting component and a driving component. The limiting component is used to limit the hydrogen storage container. The limiting component includes a moving seat 201 and a magic tape 202. A placing groove matching the hydrogen storage container is formed on the moving seat 201. The magic tape 202 is arranged on the moving seat 201 and is used to bundle and limit the hydrogen storage container. The hydrogen storage container is placed inside the placing groove. The magic tape 202 includes a sub-tape and a mother-tape. By sticking the sub-tape and the mother-tape tightly, the hydrogen storage container can be restricted inside the placing groove, and the air inlet of the hydrogen storage container is adjusted to be in a vertical state, which is convenient for connecting the connecting pipe 501 and the air inlet subsequently. The driving component is used to drive the limiting component and the hydrogen storage container to move. The driving component includes a driving shaft 301 and a walking rod 302. The driving shaft 301 is rotatably arranged on the moving seat 201. A plurality of walking rods 302 are arranged. The walking rods 302 are fixedly connected to the outside of the driving shaft 301. Two driving shafts 301 are provided. The two driving shafts 301 are located on both sides of the moving seat 201. The two driving shafts 301 are connected by a sprocket and chain drive. A motor 303 is installed on the moving seat 201. One of the driving shafts 301 is fixedly connected to the output end of the motor 303. The driving shaft 301 connected to the motor 303 can be driven to rotate by the motor 303. Under the action of the sprocket and chain, the two driving shafts 301 rotate synchronously. The walking rod 302 contacts the inner bottom wall of the hydrogenation tank 2 during rotation. The reaction force of the hydrogenation tank 2 on the walking rod 302 is used to push the moving seat 201 and the hydrogen storage container to move. A plurality of balls 304 are rotatably connected to the bottom end of the moving seat 201, which is convenient for reducing the resistance during the movement of the moving seat 201.

[0064] To ensure the stability of the moving seat 201, a sliding component is further included. The sliding component is arranged on the moving seat 201 and includes a sliding plate 401 and a limiting plate 402. The sliding plate 401 is fixedly connected to the bottom end of the moving seat 201. A chute matching the sliding plate 401 is opened on the inner bottom wall of the hydrogenation tank 2. The sliding plate 401 and the chute are in sealed sliding fit. The limiting plate 402 is fixedly connected to the hydrogenation tank 2. When the hydrogen storage container moves to the connecting pipe 501, the sliding plate 401 contacts the limiting plate 402. The moving seat 201 is limited by the sliding fit between the sliding plate 401 and the chute, so that the moving seat 201 slides along a specific track. The length of the sliding plate 401 is greater than the lengths of the buffer bin and the hydrogenation bin. When the moving seat 201 is located inside the buffer seat, the end of the sliding plate 401 is located inside the hydrogenation bin. When the moving seat 201 is located inside the hydrogenation bin, the other end of the sliding plate 401 is located inside the buffer bin, closing the space between the buffer bin and the hydrogenation bin. When the moving seat 201 moves inside the hydrogenation bin and the end of the sliding plate 401 contacts the limiting plate 402, the position of the connecting pipe 501 corresponds to the air inlet of the hydrogen storage container, and the connecting pipe 501 and the hydrogen storage container can be connected to add hydrogen into the hydrogen storage container.

[0065] The conveying component is used to convey hydrogen to the hydrogen storage container. The conveying component includes a connecting pipe 501. The connecting pipe 501 is communicated with the air outlet of the compressor 1 through a telescopic hose. A valve is installed on the connecting pipe 501. The connecting pipe 501 is arranged to be liftable inside the hydrogenation bin. An electric cylinder two 502 is installed inside the hydrogenation bin. The output end of the electric cylinder two 502 is fixedly connected with a lifting plate 503. A driving ring 504 is fixedly connected to the outside of the connecting pipe 501. A compression spring is arranged between the driving ring 504 and the lifting plate 503. The connecting pipe 501 is communicated with the air inlet of the hydrogen storage container. The lifting plate 503 can be driven to lift by the electric cylinder two 502, so as to drive the connecting pipe 501 to lift. The telescopic of the telescopic hose can adapt to the lifting of the connecting pipe 501. The bottom end of the connecting pipe 501 is rotatably communicated with a joint. The joint is threadedly connected and communicated with the air inlet of the hydrogen storage container. The joint is threadedly connected to the air inlet of the hydrogen storage container. The joint is limited to a certain extent by the compression spring to prevent the joint from disengaging from the air inlet of the hydrogen storage container. The hydrogen in the hydrogen station is compressed by the compressor 1 and conveyed to the inside of the hydrogen storage container through the connecting pipe 501 for storage.

[0066] The cooling component is used to cool the hydrogen storage container inside the hydrogenation chamber. The cooling component includes an air supply pipe 601, a connecting pipe 602, and a vacuum pump 603. The air supply pipe 601 is connected to the air outlet of the compressor 1, and a valve is installed on the air supply pipe 601. The connecting pipe 602 is installed on the opening and closing plate 101 between the buffer chamber and the hydrogenation chamber, and a valve is installed on the connecting pipe 602. The air extraction port of the vacuum pump 603 is connected to the buffer chamber. After the hydrogen storage container enters the buffer chamber, the excess air inside the buffer chamber can be pumped out through the vacuum pump 603. At this time, the opening and closing plate 101 between the buffer chamber and the hydrogenation chamber is in the closed state. By opening the valves of the air supply pipe 601 and the connecting pipe 501, hydrogen is transported into the hydrogenation chamber, making the inside of the hydrogenation chamber in a low-temperature hydrogen environment. The outside of the hydrogenation tank 2 is fixedly connected with a heat insulation layer, which can ensure the low-temperature environment inside the hydrogenation chamber. Then, by opening the connecting pipe 602 through the valve, the hydrogen inside the hydrogenation chamber enters the buffer chamber, so that the inside of the buffer chamber also becomes a hydrogen environment. Then, the vacuum pump 603 and the connecting pipe 602 are closed, the opening and closing plate 101 between the buffer chamber and the hydrogenation chamber is opened, and the hydrogen storage container is driven into the hydrogenation chamber through the moving seat 201. The air outlet of the vacuum pump 603 can be connected to an exhaust pipe and a gas collection tank through a three-way valve. The exhaust pipe is connected to the outside. When pumping air after the hydrogen storage container enters the buffer chamber, the vacuum pump 603 is connected to the exhaust pipe to discharge the excess air inside the buffer chamber. After the hydrogen storage container enters the hydrogenation chamber, the vacuum pump 603 is connected to the gas collection tank to suck the hydrogen inside the buffer chamber into the gas collection tank, and the hydrogen can be recycled.

[0067] To improve the sealing performance between the connecting pipe 501 and the hydrogen storage container, a sealing assembly is further included. The sealing assembly includes a sealing shell 701 and a limiting ring 702. There are two sealing shells 701. The sealing shells 701 are liftable and movably arranged inside the hydrogenation chamber. An electric cylinder three 703 is installed inside the hydrogenation chamber. The output end of the electric cylinder three 703 is fixedly connected to a mounting bracket 704. Two electric cylinders four 705 are installed on the mounting bracket 704. The sealing shells 701 correspond to the electric cylinders four 705 one by one. The sealing shell 701 is fixedly connected to the output end of the electric cylinder four 705. The sealing shell 701 contacts the connecting pipe 501 and the air inlet of the hydrogen storage container. The limiting ring 702 is fixedly sleeved outside the connecting pipe 501. The limiting ring 702 contacts the inner top wall of the sealing shell 701. The electric cylinder three 703 can drive the sealing shell 701 to lift, avoiding obstruction to the movement of the hydrogen storage container. When the hydrogen storage container moves below the connecting pipe 501, the electric cylinder three 703 drives the sealing shell 701 to descend to the air inlet of the hydrogen storage container. The electric cylinder four 705 drives the two sealing shells 701 to approach each other to wrap the air inlet, restricting the air inlet of the hydrogen storage container to the vertically upward state. Then the electric cylinder four 705 drives the sealing shell 701 to move away from the air inlet. The electric cylinder two 502 drives the connecting pipe 501 to descend and press against the air inlet to connect the connecting pipe 501 and the air inlet. Then the electric cylinder three 703 drives the sealing shell 701 to wrap the air inlet and the connecting pipe 501, ensuring the sealing performance of the connection between the air inlet and the connecting pipe 501. At the same time, the sealing shell 701 positions the limiting ring 702 to prevent the connecting pipe 501 and the air inlet from separating. A pressure sensor 706 is installed inside the sealing shell 701. When leakage occurs at the connecting pipe 501 and the air inlet, the air pressure inside the sealing shell 701 increases. The pressure sensor 706 senses the hydrogen leakage, controls the valve on the connecting pipe 501 to close, stops adding hydrogen continuously, and further processes the leakage point. At the same time, both the hydrogenation chamber and the buffer chamber are in a hydrogen environment. Even if hydrogen leakage occurs, the hydrogen can be discharged into the buffer chamber and sucked into the inside of the gas collection tank through the vacuum pump 603 for recovery.

[0068] To connect the connecting pipe 501 and the hydrogen storage container, an operating assembly is further included. The operating assembly is used to connect the connecting pipe 501 and the hydrogen storage container. The operating assembly includes an operating pipe 801 and operating gloves 802. An operating opening is provided on the hydrogenation chamber. The operating pipe 801 is fixedly connected to the operating opening. The operating gloves 802 are fixedly connected to the operating pipe 801. The operating gloves 802 can be made of rubber material to prevent hydrogen leakage. An observation opening is provided on the hydrogenation tank 2. A transparent observation window is provided at the observation opening. The operator puts his hand into the inside of the operating gloves 802 to tighten and loosen the joint and the air inlet. At the same time, the connection and hydrogenation conditions can be observed through the transparent observation window.

[0069] The working principle or usage process of the hydrogenation device for the hydrogen storage container is as follows. First, open the opening and closing plate 101 between the buffer bin and the outside. The moving seat 201 is inside the buffer bin. Place the hydrogen storage container in the placement groove, bundle and limit the hydrogen storage container through the magic tape 202, and adjust the air inlet of the hydrogen storage container to face upward.

[0070] Close the opening and closing plate 101, turn on the vacuum pump 603 to pump out the air in the buffer bin, and the air is discharged through the exhaust pipe. At the same time, the compressor 1 pressurizes the hydrogen in the hydrogen station and transports it to the inside of the hydrogenation bin through the connecting pipe 501 and the air supply pipe 601, so that the inside of the hydrogenation bin is in a low-temperature hydrogen environment.

[0071] Open the opening and closing plate 101 between the buffer bin and the hydrogenation bin. The motor 303 drives the drive shaft 301 to rotate, and pushes the moving seat 201 and the hydrogen storage container to move through the walking rod 302 until they contact the sliding plate 401 and the limiting plate 402, and then close the opening and closing plate 101 between the buffer bin and the hydrogenation bin.

[0072] The electric cylinder three 703 drives the sealing shell 701 to descend to the position of the air inlet. The electric cylinder four 705 drives the sealing shells 701 to approach each other to limit the air inlet. Then the sealing shell 701 moves away from the air outlet. The electric cylinder two 502 drives the connecting pipe 501 to descend. The operator puts his hand into the operation glove 802 and screws the connector into the air inlet to connect the connecting pipe 501 and the hydrogen storage container. Then the electric cylinder four 705 drives the sealing shell 701 to wrap the air inlet and the connecting pipe 501.

[0073] Close the air supply pipe 601. The compressor 1 sends gas into the hydrogen storage container through the connecting pipe 501. The sealing shell 701 seals the connecting pipe 501 and the air inlet. The air pressure sensor 706 monitors hydrogen leakage. If leakage occurs, close the connecting pipe 501.

[0074] After hydrogenation, the electric cylinder four 705 drives the sealing shell 701 to move away from the connecting pipe 501. The electric cylinder three 703 drives the sealing shell 701 to rise. Unscrew the connector through the operation glove 802. The electric cylinder two 502 drives the connecting pipe 501 to rise. Open the opening and closing plate 101 between the buffer bin and the hydrogenation bin. The motor 303 rotates in the reverse direction to drive the moving seat 201 to drive the hydrogen storage container to move into the buffer bin. Close the opening and closing plate 101 between the buffer bin and the hydrogenation bin. The vacuum pump 603 sucks the hydrogen in the buffer bin into the gas collection box. Then open the opening and closing plate 101 between the buffer bin and the outside, take out the hydrogen storage container, put the subsequent hydrogen storage container into the placement groove, and perform the subsequent hydrogenation work.
