Description

Technical Field

[0001] This utility model relates to the field of gas storage technology, specifically to a gas storage device with a leak detection function. Background Technology

[0002] Hydrogen is an important raw material in the chemical industry and is widely used in the synthesis of ammonia. At the same time, hydrogen is considered a form of clean energy and can be used as fuel for fuel cells to generate electricity and water without producing greenhouse gases. However, the storage and transportation of hydrogen present certain challenges because its low density and flammability make safety management very important.

[0003] For example, Chinese patent application CN212840714U discloses a storage ventilation structure for a hydrogen tank, which includes a box with a flow cavity and a hydrogen tank placed in the flow cavity. The box includes a bottom plate, a side plate and a top plate, and the side plate has a flow hole through which gas flows.

[0004] However, the storage ventilation structure of this hydrogen tank cannot detect hydrogen leaks during use, making it difficult to repair and replace the tank in a timely manner when a gas leak occurs.

[0005] Based on this, the present invention designs a gas storage device with leakage detection function to solve the above problems. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0029] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-4 A gas storage device with a leak detection function includes a storage component 1 and a leak detection component 2.

[0030] The leak detection component 2 includes a sealing component 22 for sealing the storage component 1, a moving component 21 for driving the sealing component 22 to move, and a detection component 23 for detecting the gas concentration inside the sealing component 22.

[0031] When the gas storage device with leakage detection function is in normal use, multiple storage components 12 are placed inside the frame 11 for storage. The moving component 21 is activated to move the sealing component 22 above the storage component 12, and the sealing component 22 is activated to seal the easily leaking parts of the storage component 12. The gas concentration inside the sealing component 22 is detected by the detection component 23, which can determine in real time whether the storage component 12 is leaking.

[0033] The frame 11 includes a lower support 111, an upper support 112, and a supporting pad 113. The upper support 112 is fixedly installed on the upper end of the lower support 111.

Multiple supporting pads 113 are fixedly installed at the bottom of the lower support 111 corresponding to the storage component 12. The supporting pads 113 are arranged in a ring.

[0034] The storage component 12 is provided in multiple ways. The storage component 12 includes a gas cylinder body 121 and a nozzle 122. The nozzle 122 is fixedly installed at the mouth of the gas cylinder body 121. The multiple nozzles 122 correspond one-to-one with the supporting pads 113. The gas cylinder body 121 is placed on the supporting pads 113. The multiple gas cylinder bodies 121 are arranged adjacent to each other and close together. The outermost gas cylinder body 121 is fitted and connected to the lower bracket 111.

[0035] The movable component 21 includes a threaded rod 211, a slide rod 212, a motor 213, and a movable plate 214. The threaded rod 211 and the slide rod 212 are arranged parallel to each other inside the upper bracket 112. The threaded rod 211 is rotatably connected to the upper bracket 112, and the slide rod 212 is fixedly connected to the upper bracket 112. The threaded rod 211 is threadedly connected to the movable plate 214, and the slide rod 212 is slidably connected to the movable plate 214. The motor 213 is fixedly installed on one side of the upper bracket 112, and the output end of the motor 213 is fixedly connected to one end of the threaded rod 211. The movable plate 214 is slidably connected to the upper bracket 112 and is connected to the sealing component 22.

[0036] The sealing component 22 includes a driving structure and a sealing structure. The driving structure is mounted on the moving plate 214, and the sealing structure is mounted on the lower end of the driving structure. The driving structure is connected to the detection component 23.

[0037] The driving structure includes an electric cylinder 221, a sliding outer shell 222, and a sliding inner shell 223. The electric cylinder 221 is fixedly installed on the upper end of the moving plate 214. The output end of the electric cylinder 221 is fixedly connected to the inner side of the sliding outer shell 222. The inner side of the sliding outer shell 222 is slidably and sealed to the outer side of the sliding inner shell 223. The upper end of the sliding inner shell 223 is fixedly connected to the moving plate 214. The lower end of the sliding outer shell 222 is connected to the sealing structure.

[0038] Multiple sealing structures are provided in a one-to-one correspondence with the gas cylinder body 121. The sealing structure includes a sealing cylinder 224 and a sealing pad 225. The sealing cylinder 224 is fixedly installed at the lower end of the sliding outer shell 222. The lower end of the sealing cylinder 224 is fixedly connected to the sealing pad 225. The lower end of the sealing pad 225 is arc-shaped to match the upper end of the gas cylinder body 121. The lower end of the sliding outer shell 222 has multiple through holes corresponding to the sealing cylinder 224 to connect the inner side of the sliding outer shell 222 with the inner side of the sealing cylinder 224.

[0039] A sealing quick-connect interface 226 is also fixedly installed on the movable plate 214.

[0040] The detection component 23 includes a concentration detection structure 231, which is fixedly installed at the lower end of the moving plate 214. The concentration detection structure 231 is located inside the sliding outer shell 222 and the sliding inner shell 223. The concentration detection structure 231 is a fixed hydrogen detector, which is a mature technology in this field.

[0041] When the gas storage device with leakage detection function is in normal use, the gas is stored inside the gas cylinder body 121 and sealed with the nozzle 122. Multiple gas cylinder bodies 121 are placed inside the lower support 111, and the supporting pad 113 supports and cushions the gas cylinder bodies 121. The motor 213 is started, and the motor 213 drives the threaded rod 211 to rotate. The threaded rod 211 drives the moving plate 214 to slide along the slide rod 212, moving the moving plate 214 to the gas cylinder. Above the cylinder 121, the electric cylinder 221 is activated. The electric cylinder 221 drives the sliding outer shell 222 to move downward along the sliding inner shell 223. The sliding outer shell 222 then drives the sealing cylinder 224 and the sealing pad 225 to move downward in sequence. The sealing pad 225 causes the cylinder body 121 to press against the supporting pad 113 and make the cylinder body 121 contact the bottom of the lower bracket 111 to complete the fixation. The sealing pad 225 is then attached to the upper end of the cylinder body 121 to seal it. When the cylinder body 121... When gas leaks from the connection between the cylinder body 121 and the nozzle 122, the gas moves from the sealing cylinder 224 through the sliding outer shell 222 to the inside of the sliding outer shell 222 and the sliding inner shell 223. The concentration detection structure 231 detects the increase in gas concentration. During maintenance, the gas inside the sliding outer shell 222 and the sliding inner shell 223 is first extracted through the sealing quick interface 226. The annular arrangement of the supporting soft pad 113 provides buffer protection for the cylinder body 121 when it is taken out. At the same time, when the electric cylinder 221 drives the sealing soft pad 225 to press the cylinder body 121 downward, it can ensure that the cylinder body 121 is attached and fixed to the bottom of the lower bracket 111, and there will be no floating that would cause incomplete sealing. The arrangement of the sliding outer shell 222 and the sliding inner shell 223, together with the sealing cylinder 224, seals the connection between the cylinder body 121 and the nozzle 122, which can prevent the gas from escaping after leakage and reduce air pollution.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
