Description

Technical Field

[0001] This utility model belongs to the field of compressor-related technical technology, specifically a leak-proof hydrogen compressor. Background Technology

[0002] A hydrogen compressor is a key piece of equipment specifically designed to pressurize hydrogen. It mechanically compresses low-pressure hydrogen to a high-pressure state to meet the needs of storage, transportation, or industrial applications (such as hydrogen refueling stations, chemical production, and energy systems). Its design must take into account the flammable and explosive characteristics of hydrogen, and it adopts leak-proof and explosion-proof materials and special sealing technologies. Common types include diaphragm, piston, and centrifugal compressors. They are characterized by high efficiency, low energy consumption, and safety and reliability, and are an important link in the hydrogen energy industry chain.

[0003] Patent document CN218493748U describes a hydrogen compressor, including a first protective shell. A hydrogen compressor body is fixedly connected to the top of the first protective shell. A second protective shell is movably installed on the top of the hydrogen compressor body. First grooves are provided on both sides of the second protective shell. A limiting plate is fixedly connected inside the first groove. A disassembly hole is provided in the middle of the limiting plate. A fixing post is slidably connected inside the disassembly hole. A sliding groove is provided on the inner wall of the first groove. The sliding groove is arc-shaped. A limiting ring is rotatably connected to the outer wall of the fixing post. The outer wall of the limiting ring is slidably connected to the inner wall of the sliding groove. A first spring is fixedly connected between the limiting plate and the limiting ring.

[0004] Existing hydrogen compressors have certain shortcomings in use. Traditional hydrogen compressors do not have a leak-proof structure. Hydrogen is different from ordinary gases. Hydrogen is flammable and explosive. Its leakage poses certain safety hazards. Traditional hydrogen compressors use flange structures to fix the pipeline structure, which allows gas to diffuse directly into the air when it leaks, resulting in poor safety. At the same time, the pipeline connection does not have a multi-seal structure, which reduces the sealing performance of the pipeline connection. In summary, the existing technology of traditional hydrogen compressors uses flange structures to fix the pipeline structure, which allows gas to diffuse directly into the air when it leaks, resulting in poor safety. Utility Model Content

[0005] This invention provides a leak-proof hydrogen compressor, which solves the problem of poor safety in existing hydrogen compressors that use flange structures to fix the pipeline structure, allowing gas to diffuse directly into the air when leaking. A leak-proof hydrogen compressor includes a fixed base and a compression cylinder. The compression cylinder is fixedly installed on the upper outer surface of the fixed base. A connecting gas pipe is fixedly installed at the middle position on both sides of the fixed base. A leak-proof component for connecting the gas pipe is movably installed on the outer surface of the connecting gas pipe. The leak-proof component includes a sealing sleeve and an annular groove. The annular groove is located at the middle position of the inner side of the sealing sleeve. A gas collecting pipe is fixedly installed at the middle position of the upper outer surface of the sealing sleeve. A gas collecting bottle for use with the sealing sleeve is fixedly installed on one side of the fixed base.

[0006] As a further technical solution of this utility model, the gas collecting bottle and the gas collecting pipe are fixed by a flexible connection of the connecting pipe, and the gas collecting pipe and the annular groove are connected through the pipe. The sealing sleeve is used to connect the gas collecting pipe and the pipeline structure through the threaded structure, so that the hydrogen in the pipeline is transported to the connecting gas pipe and enters the compression cylinder for compression. The sealing sleeve can collect excess hydrogen and prevent hydrogen leakage.

[0007] As a further technical solution of this utility model, the inner surface of the sealing sleeve is provided with a threaded groove, and both sides of the sealing sleeve are provided with a handle. The user uses the handle to drive the sealing sleeve, so that the sealing sleeve completes the connection and fixation between the sealing sleeve and the connecting air pipe and the pipeline through the threaded groove.

[0008] As a further technical solution of this utility model, both ends of the connecting pipe are provided with sealing joints. The connecting pipe and the gas collecting bottle, as well as the connecting pipe and the gas collecting pipe, are all fixed together by the sealing joints. By using the sealing joints, the sealing performance when the two ends of the connecting pipe are connected can be improved.

[0009] As a further technical solution of this utility model, the sealing joint includes a first ferrule and a second ferrule. The first ferrule is fixedly installed on the outer surface of one end of the second ferrule. The first ferrule and the second ferrule can be used to complete the docking operation of the connecting pipe and the gas collecting pipe.

[0010] As a further technical solution of this utility model, the inner sides of the first and second ferrules are provided with several sets of sealing rings, which are distributed at equal intervals. The sealing rings can improve the sealing performance when the first and second ferrules are docked.

[0011] As a further technical solution of this utility model, the surfaces of the connecting tube and the gas collecting tube are provided with arc-shaped grooves for use with the sealing ring. The arc-shaped grooves are used to connect with the sealing ring, thereby increasing the contact surface after the first ferrule and the second ferrule are connected, which can prevent them from falling off and increase the sealing performance.

[0012] As a further technical solution of this utility model, both the first and second ferrules are provided with a tapered plug in the middle. The outer surface of the side of the tapered plug is inclined. By using the tapered plug, the resistance when the first and second ferrules are connected and installed can be reduced.

[0013] As a further technical solution of this utility model, several sets of pistons are movably installed inside the compression cylinder. The crankshaft is driven by a motor, which causes the crankshaft to drive the pistons to reciprocate, thereby completing the hydrogen compression process inside the compression cylinder.

[0014] As a further technical solution of this utility model, a pressure gauge is provided at the front end of the fixed base, and a controller is provided at the front end of the fixed base on one side of the pressure gauge, so that the pressure inside the compressed cylinder can be detected by the pressure gauge.

[0015] The beneficial effects of this utility model are as follows: By setting a leak-proof component, this utility model provides a gas collection structure for the leak-proof hydrogen compressor during use, preventing hydrogen from diffusing into the air and improving the safety of the hydrogen compressor during operation. During operation, the sealing sleeve is used to connect the gas pipe and the pipeline structure through a threaded structure, allowing the hydrogen in the pipeline to be transported to the connecting gas pipe, and then enters the compression cylinder for compression. The sealing sleeve can collect excess hydrogen to prevent hydrogen leakage. Hydrogen overflowing between the gas pipe and the pipeline is guided to the gas collecting pipe through the annular groove, and then transported to the inside of the gas collecting bottle for collection through the connecting pipe. The leak-proof component and the sealing sleeve form a hydrogen collection structure between the gas pipe and the pipeline, effectively preventing hydrogen leakage. By setting a sealing joint, the use of leak-proof components is optimized when the leak-proof hydrogen compressor is used, and the sealing performance of its pipeline connection structure is improved. During operation, the first and second ferrules can be used to complete the connection operation of the connecting pipe and the gas collecting pipe. Several sets of sealing rings are evenly distributed. The setting of the sealing rings can improve the sealing performance when the first and second ferrules are connected. The arc-shaped grooves on the surface of the connecting pipe and the gas collecting pipe connect with the sealing rings, thereby increasing the contact surface after the first and second ferrules are connected, which can prevent them from falling off and increase the sealing performance. The use of the conical plug can reduce the resistance when the first and second ferrules are connected and installed. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figures 1-3 As shown, a leak-proof hydrogen compressor includes a fixed base 1 and a compression cylinder 3. The compression cylinder 3 is fixedly installed on the upper outer surface of the fixed base 1. A connecting gas pipe 7 is fixedly installed at the middle position on both sides of the fixed base 1. A leak-proof component 4 for connecting the gas pipe is movably installed on the outer surface of the connecting gas pipe 7. The leak-proof component 4 includes a sealing sleeve 9 and an annular groove 10. The annular groove 10 is located at the middle position of the inner side of the sealing sleeve 9. A gas collecting pipe 17 is fixedly installed at the middle position of the upper outer surface of the sealing sleeve 9. A gas collecting bottle 5 for use with the sealing sleeve 9 is fixedly installed on one side of the fixed base 1.

[0021] The gas collecting bottle 5 and the gas collecting pipe 17 are fixed together by connecting pipe 6. The gas collecting pipe 17 and the annular groove 10 are connected through each other. The sealing sleeve 9 is used to connect the gas collecting pipe 7 and the pipeline structure through the threaded structure, so that the hydrogen in the pipeline is transported to the connecting gas collecting pipe 7 and enters the compression cylinder 3 for compression. The sealing sleeve 9 can collect excess hydrogen and prevent hydrogen leakage.

[0022] The inner surface of the sealing sleeve 9 is provided with a threaded groove 11, and both sides of the sealing sleeve 9 are provided with a handle. The user uses the handle to drive the sealing sleeve 9, so that the sealing sleeve 9 completes the connection and fixation between the sealing sleeve 9 and the connecting air pipe 7 and the pipeline through the threaded groove 11.

[0023] Both ends of the connecting pipe 6 are equipped with sealing joints 12. The connecting pipe 6 and the gas collecting bottle 5, as well as the connecting pipe 6 and the gas collecting pipe 17, are all connected and fixed by the sealing joints 12. The sealing joints 12 can improve the sealing performance when the two ends of the connecting pipe 6 are connected.

[0024] The sealing connector 12 includes a first ferrule 13 and a second ferrule 14. The first ferrule 13 is fixedly installed on the outer surface of one end of the second ferrule 14. The first ferrule 13 and the second ferrule 14 can be used to complete the docking operation between the connecting pipe 6 and the gas collecting pipe 17.

[0025] The inner sides of the first ferrule 13 and the second ferrule 14 are provided with several sets of sealing rings 16. The sets of sealing rings 16 are distributed at equal intervals. The sealing rings 16 can improve the sealing performance when the first ferrule 13 and the second ferrule 14 are docked.

[0026] Both the flexible connector 6 and the gas collecting pipe 17 have arc-shaped grooves on their surfaces to cooperate with the sealing ring 16. The arc-shaped grooves are used to connect with the sealing ring 16, thereby increasing the contact surface of the first ferrule 13 and the second ferrule 14 after docking, which can prevent them from falling off and increase the sealing performance.

[0027] Both the first ferrule 13 and the second ferrule 14 are provided with a tapered plug 15 in the middle. The outer surface of the side of the tapered plug 15 is beveled. By using the tapered plug 15, the resistance when the first ferrule 13 and the second ferrule 14 are connected and installed can be reduced.

[0028] Several sets of pistons are installed inside the compression cylinder 3. A pressure gauge 2 is provided at the front end of the fixed base 1. The crankshaft is driven by a motor, which causes the pistons to move back and forth, thus completing the hydrogen compression process inside the compression cylinder 3.

[0029] A pressure gauge 2 is provided at the front end of the fixed base 1, and a controller 8 is provided at the front end of the fixed base 1 on one side of the pressure gauge 2. The pressure gauge 2 can be used to detect the pressure inside the compression cylinder 3.

[0030] A leak-proof hydrogen compressor, when in use, incorporates a leak-proof component 4 to create a gas collection structure, preventing hydrogen from diffusing into the air and improving the safety of the compressor. During operation, a sealing sleeve 9 connects to a gas pipe 7 and a pipeline structure via a threaded connection, allowing hydrogen in the pipeline to be transported to the connecting gas pipe 7 and then into the compression cylinder 3 for compression. The sealing sleeve 9 collects excess hydrogen, preventing leakage. Hydrogen overflowing between the gas pipe and the pipeline is guided through an annular groove 10 to a gas collecting pipe 17, which then transports it to the inside of a gas collecting bottle 5 via a connecting hose 6. The leak-proof component 4, along with the sealing sleeve 9, forms a hydrogen collection structure between the gas pipe and the pipeline, effectively preventing hydrogen leakage. By setting the sealing joint 12, the use of the leak-proof component 4 is optimized when the leak-proof hydrogen compressor is used, and the sealing performance of its pipeline connection structure is improved. During operation, the first ferrule 13 and the second ferrule 14 can be used to complete the connection operation of the connecting pipe 6 and the gas collecting pipe 17. Several sets of sealing rings 16 are evenly distributed. The setting of the sealing rings 16 can improve the sealing performance when the first ferrule 13 and the second ferrule 14 are connected. The arc-shaped grooves on the surfaces of the connecting pipe 6 and the gas collecting pipe 17 connect with the sealing rings 16, thereby increasing the contact surface after the first ferrule 13 and the second ferrule 14 are connected, which can prevent detachment and increase the sealing performance. The setting of the tapered plug 15 can reduce the resistance when the first ferrule 13 and the second ferrule 14 are connected.
