Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen storage and supply, and specifically, it is an open-type hydrogen cylinder group hydrogen supply and storage device. Background Art

[0002] Existing hydrogen supply devices are mostly accessories for test benches, arranged relying on factory buildings. However, national standards have high requirements for the fire and explosion prevention grades of hydrogen-related factory buildings, with high costs, cumbersome gas supply switching, inability to view gas consumption in real time, and poor safety.

[0003] After retrieval, Chinese Patent Publication No. CN111578125A discloses a hydrogen supply system, a safe and efficient unattended high-pressure hydrogen supply system for power plants. It includes a hydrogen storage unit group rack, and the hydrogen storage unit group rack is connected to a hydrogen manifold through a high-pressure hydrogen transmission hose. A hydrogen pressure regulator is provided at the end of the hydrogen storage unit group rack, and the hydrogen pressure regulator is connected to the high-pressure hydrogen transmission hose. A high-pressure hydrogen transmission hose cylinder valve is provided on the high-pressure hydrogen transmission hose; a hydrogen supply valve, a vent valve, a replacement valve, and a sampling valve are provided on the hydrogen manifold, and the vent valve is also connected to a flame arrester. This invention uses a specially modified imported pressure regulator, and there will be no air leakage into the high-pressure hydrogen transmission hose and the hydrogen manifold when replacing the hydrogen storage unit group rack; there is no need for inert gas purging, with low labor intensity. However, the device lacks protection, has poor isolation, and the hydrogen replacement process is cumbersome. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an open-type hydrogen cylinder group hydrogen supply and storage device to achieve the purposes of being simple and reliable, independent of the factory building, easy to operate for gas replacement, low cost, and high safety.

[0005] To achieve the above purpose, the utility model adopts the following technical means:

[0006] An open-type hydrogen cylinder group hydrogen supply and storage device, comprising:

[0007] A base for placing a modular hydrogen mechanism;

[0008] The frame structure includes an explosion-proof plate provided at the edge of the top surface of the base platform and several support frames. The support frame includes a first strut provided at the corner of the base platform and a second strut provided between the two first struts on the opposite side of the explosion-proof plate. The explosion-proof plate, the first strut, and the second strut surround to form a receiving space for placing the modular hydrogen mechanism. A slanted rain shield is installed on the top side of the explosion-proof plate, and the vertical projection of the rain shield completely covers the base platform. One side of the rain shield away from the explosion-proof plate slopes upward. The top end of the first strut is fixedly connected to the bottom surface of the rain shield. The top side of the explosion-proof plate and the first strut are connected by a horizontal first reinforcing rod. The top sides of the two first struts are connected by a horizontal second reinforcing rod. The top end of the second strut is fixedly connected to the bottom surface of the second strut.

[0009] Preferably, there are two second struts. A first hollow door is installed between the explosion-proof plate and the first strut. A second hollow door is installed between the first strut and the second strut. A third hollow door is installed between the two second struts. The space between the first strut and the second strut serves as a first receiving cavity for placing the modular hydrogen mechanism. The space between the two second struts serves as a second receiving cavity for placing the modular hydrogen mechanism.

[0010] Furthermore, the hydrogen supply pipeline and the flushing pipeline are both provided on the explosion-proof wall.

[0011] Even further, an inclined slope is installed on the side edge of the base platform for loading and unloading the modular hydrogen mechanism.

[0012] Even further, the modular hydrogen mechanism includes a hollow box. The hollow box is filled with several hydrogen tanks whose side walls are in contact with each other. A lockable universal wheel is installed on the bottom surface of the hollow box. The gas outlet end of the hydrogen tank is connected to the hydrogen supply pipeline through a pipeline system.

[0013] Even further, the pipeline system includes a connecting pipeline that connects the hydrogen tanks in series. The end gas outlet of the connecting pipeline is connected to a collecting pipe installed on the top surface of the hollow box. A switch valve and a pressure gauge are provided on the collecting pipe. The gas outlet end of the collecting pipe is connected to the hydrogen supply pipeline.

[0014] During the use of the present utility model, the following beneficial effects are achieved:

[0015] By orienting the explosion-proof panel of the frame structure towards the factory and utilizing the three-sided hollow design of the frame structure, ventilation can be enhanced while ensuring the protective effect towards the factory direction. In this way, even if hydrogen leakage occurs, the hydrogen concentration inside the frame structure can be rapidly reduced, minimizing the explosion risk. Moreover, the use of an inclined rain shield not only serves the purpose of rain protection but also effectively prevents, in the event of leakage during ventilation inside the frame structure, the direct blowing of high-concentration air containing hydrogen towards the factory building. Under the structure of the inclined rain shield, the air blowing towards the factory building direction, after entering the frame structure, can be diverted by the inclined rain shield and flow out from the bottom side or both sides of the frame structure, rather than directly blowing the air carrying hydrogen towards the factory building, thus significantly improving the safety of the factory building in the case of hydrogen leakage. During gas supply, a modular hydrogen mechanism is used for gas supply. After a modular hydrogen mechanism runs out of gas, the gasless modular hydrogen mechanism can be specifically replaced, thereby avoiding the situation of gas cut-off during hydrogen replacement.

[0027] Please refer to Figures 1 to 4 as shown in the following, an open-type hydrogen cylinder group hydrogen supply and storage device, comprising:

[0028] a base 1 for placing a modular hydrogen mechanism 2;

[0029] The frame structure includes an explosion-proof plate 4 provided at the edge of the top surface of the base 1 and several support frames. The support frames include a first support rod 3 provided at the corner of the base 1, and a second support rod 5 provided between the two first support rods 3 on the opposite side of the explosion-proof plate 4. The explosion-proof plate 4, the first support rod 3, and the second support rod 5 surround to form a receiving space for placing the modular hydrogen mechanism 2. A slanted rain shield 6 is installed on the top side of the explosion-proof plate 4. The vertical projection of the rain shield 6 completely covers the base 1. One side of the rain shield 6 away from the explosion-proof plate 4 slopes upward. The top end of the first support rod 3 is fixedly connected to the bottom surface of the rain shield 6. The top side of the explosion-proof plate 4 and the first support rod 3 are connected by a horizontal first reinforcing rod 7. The top sides of the two first support rods 3 are connected by a horizontal second reinforcing rod 8. The top end of the second support rod 5 is fixedly connected to the bottom surface of the second support rod 5.

[0030] In this way, by facing the explosion-proof plate 4 of the frame structure towards the factory and using the three-sided hollow design of the frame structure, ventilation can be enhanced while ensuring the protective effect on the factory side. Even if hydrogen leaks occur, the hydrogen concentration inside the frame structure can be quickly reduced, thereby reducing the explosion risk. Moreover, the use of the slanted rain shield 6 can not only achieve the purpose of rain protection but also effectively prevent, when ventilation occurs inside the frame structure and in case of leakage, the high-concentration air with hydrogen from being directly blown towards the factory building. Under the structure of the slanted rain shield 6, the air blowing towards the factory building direction can be deflected by the slanted rain shield 6 after entering the frame structure, causing it to flow out from the bottom side or both sides of the frame structure, instead of directly blowing the air carrying hydrogen towards the factory building, greatly improving the safety of the factory building in case of hydrogen leakage. During gas supply, the modular hydrogen mechanism 2 is used for gas supply. After one modular hydrogen mechanism 2 runs out of gas, the modular hydrogen mechanism 2 without gas can be replaced specifically, thus avoiding the situation of gas cut-off during hydrogen replacement.

[0031] Furthermore, specifically, there are two second support rods 5. A first hollow door 9 is installed between the explosion-proof plate 4 and the first support rod 3. A second hollow door 10 is installed between the first support rod 3 and the second support rod 5. A third hollow door 11 is installed between the two second support rods 5. The space between the first support rod 3 and the second support rod 5 serves as a first receiving cavity for placing the modular hydrogen mechanism 2. The space between the two second support rods 5 serves as a second receiving cavity for placing the modular hydrogen mechanism 2.

[0032] Thus, the second rod 5 is used to divide the frame structure into three cavities, namely two first accommodation cavities and one second accommodation cavity. In this way, by respectively controlling the opening and closing of the first hollow door 9, the second hollow door 10, and the third hollow door 11, the modular hydrogen mechanism 2 of air can be quickly pushed out from the base 1 as needed, and then the modular hydrogen mechanism 2 filled with gas can be pushed in to quickly complete the replacement of the modular hydrogen mechanism 2.

[0033] Furthermore, the hydrogen supply pipeline and the flushing pipeline are both arranged on the explosion-proof wall.

[0034] Furthermore, an inclined slope is installed on the side edge of the base 1 for loading and pushing out the modular hydrogen mechanism 2.

[0035] Furthermore, for the modular hydrogen mechanism 2, the modular hydrogen mechanism 2 includes a hollow box 12, and a number of hydrogen gas cylinders 13 with their side walls abutting against each other are filled in the hollow box 12. A lockable universal wheel is installed on the bottom surface of the hollow box 12, and the gas outlet end of the hydrogen gas cylinder 13 is communicated with the hydrogen supply pipeline through a pipeline system.

[0036] Furthermore, the pipeline system includes a connecting pipeline 14 that connects the hydrogen gas cylinders 13 in series in sequence. The end gas outlet end of the connecting pipeline 14 is communicated with a collecting pipe 15 installed on the top surface of the hollow box 12. A switching valve and a pressure gauge are arranged on the collecting pipe 15, and the gas outlet end of the collecting pipe 15 is communicated with the hydrogen supply pipeline.

[0037] In this way, by using the hydrogen gas cylinders 13 connected in series in a modular hydrogen mechanism 2, the gas in a number of hydrogen gas cylinders 13 can be transported as a whole, avoiding the complication of the equipment for separately opening the hydrogen gas cylinders 13, and solving the problem of gas leakage from the hydrogen gas cylinders 13 when a single hydrogen gas cylinder 13 is opened.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
