Therefore, a gaseous high-pressure hydrogen storage rapid ionic liquid compressor is proposed to solve the above problems. Summary of the Utility Model

[0004] To make up for the above deficiencies, the utility model provides a gaseous high-pressure hydrogen storage rapid ionic liquid compressor, aiming to improve the problem that the compressor in the prior art cannot cool down, thereby affecting the compression effect of hydrogen.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Referring to Figure 2 , an embodiment provided by the present utility model: A gaseous high-pressure hydrogen storage rapid ionic liquid compressor includes a compression chamber 1. A motor 2 is installed on one side outside the compression chamber 1, and the compression chamber 1 serves to support and fix the position of the motor 2. The driving end of the motor 2 is fixedly connected to a disc 3, and starting the motor 2 drives the disc 3 to rotate. A rotating block 4 is rotatably connected to one side outside the disc 3, and the rotation of the disc 3 drives the rotation of the rotating block 4.

[0032] The other end of the rotating block 4 is rotatably connected to a connecting rod 5, and the rotation of the rotating block 4 can pull the connecting rod 5 to move up and down. The other end of the connecting rod 5 is rotatably connected to a piston 7 (as shown in the appendix Figure 2), the up and down movement of the connecting rod 5 drives the piston 7 to reciprocate. The outside of the piston 7 is slidably connected to the inner wall of the pumping tube 6, and the inside of the pumping tube 6 is pumped and pressed. The top of the pumping tube 6 is fixedly connected with a top plate 8. The pumping tube 6 supports and fixes the top plate 8. On the other side inside the top plate 8, an air inlet pipe 9 is fixedly connected. When the piston 7 moves downward, the air outlet pipe 14 is closed, enabling the gas on the side of the air inlet pipe 9 to enter the inside of the pumping tube 6.

[0033] On the other side outside the compression chamber 1, a liquid inlet pipe 12 is fixedly connected. When the pressure inside the compression chamber 1 becomes lower during the movement of the piston 7, the liquid on one side of the liquid inlet pipe 12 will enter the inside of the compression chamber 1 to balance the pressure. The other end of the liquid inlet pipe 12 is fixedly connected to a cooling box 11, (as shown in the appendix Figure 2 ) What is placed inside the cooling box 11 is ionic liquid, enabling the ionic liquid to enter the inside of the compression chamber 1, so that the mechanical structure in the pumping and pressing device can directly contact the ionic liquid. The top of the cooling box 11 is fixedly connected with a liquid replacement port 13 for adding and replacing the ionic liquid that has been used for a period of time.

[0034] The top of the compression chamber 1 is fixedly connected with a liquid outlet pipe 10. The other end of the liquid outlet pipe 10 is fixedly connected inside the cooling box 11. When the pressure increases during the pumping process of the piston 7, the ionic liquid that entered the inside of the compression chamber 1 before will return to the inside of the cooling box 11 through the liquid outlet pipe 10, forming a cooling cycle. Ionic liquid is a liquid composed of ions, usually having low volatility and high thermal stability, and is used for lubrication and cooling in this compressor because its excellent chemical stability and thermal stability can improve the working efficiency and service life of the compressor.

[0035] Refer to Figure 1 、 Figure 3 And Figure 4 , the top of the compression chamber 1 is fixedly connected with a pumping tube 6. The compression chamber 1 supports the pumping tube 6. On one side inside the top plate 8, a gas storage component for preventing leakage is fixedly connected. The gas storage component includes an air outlet pipe 14. When transporting the compressed hydrogen, first close the air inlet pipe 9, so that the pumping tube 6 and the piston 7 form a closed cavity. At this time, the piston 7 moves, and an interface pipe 15 is fixedly connected to the outside of the air outlet pipe 14, enabling the compressed hydrogen to enter the interface pipe 15 through the air outlet pipe 14.

[0036] An interface pipe 15 is fixedly connected with a spiral pipe 19 on the outside. The interface pipe 15 fixes the position of the spiral pipe 19. One end of the inner wall of the threaded pipe 20 is rotatably connected with a gas storage pipe 21. The threaded pipe 20 fixes the position of the gas storage pipe 21. The outside of the threaded pipe 20 is threadedly connected to the inner wall of the spiral pipe 19 (as shown in the appendix Figure 4), Rotate the threaded pipe 20 so that the threaded pipe 20 rotates along the inner wall of the spiral pipe 19 and approaches the other end of the spiral pipe 19. The other end of the push pipe 18 is slidably connected to the threaded pipe 20. There are multiple protrusions on the outside of the push pipe 18, and some of the protrusions are arranged on both sides where the push pipe 18 extends into the threaded pipe 20. Therefore, the movement of the threaded pipe 20 will drive the movement of the push pipe 18.

[0037] One side of the outside of the interface pipe 15 is slidably connected to the push pipe 18. The outside of the first ball 17 is slidably connected to the inner wall of the interface pipe 15. The push pipe 18 moves to push the first ball 17. One side of the outside of the air outlet pipe 14 is fixedly connected to the first spring 16. The other end of the first spring 16 is fixedly connected to the first ball 17, compressing the first spring 16 (as shown in the appendix Figure 4 ). One end of the outside of the gas storage pipe 21 is fixedly connected to the second spring 25. The other end of the second spring 25 is fixedly connected to the second ball 24. The outside of the second ball 24 is slidably connected to the inner wall of the threaded pipe 20. Due to the action of the protrusions near the middle part of the outside of the push pipe 18, when the threaded pipe 20 rotates to a certain extent, the forward movement of the push pipe 18 is blocked. Due to the resistance of the first ball 17, the push pipe 18 moves backward a certain distance until the middle protrusion of the push pipe 18 is exactly clamped by the threaded pipe 20 and the interface pipe 15.

[0038] At this time, both the first ball 17 and the second ball 24 are pushed a certain distance, so that the first ball 17 does not block the nozzle of the interface pipe 15, and the second ball 24 also does not block the nozzle of the threaded pipe 20. There are gaps at both ends of the push pipe 18, so that there is a distance between the first ball 17 and the push pipe 18 for hydrogen to pass through, and there is also a distance between the second ball 24 and the other end of the push pipe 18 for hydrogen to pass through, making the entire gas storage device form a passage.

[0039] The other end of the gas storage pipe 21 is fixedly connected to the gas storage bottle 23, so that the gas inside the gas storage pipe 21 can enter the gas storage bottle 23 due to the action of air pressure. A gas locking device 22 is installed on the top of the gas storage bottle 23. After gas storage is completed, start the gas locking device 22 so that the gas that has entered the gas storage pipe 21 will not leak. The inside of the gas locking device 22 is detachably connected to the outside of the gas storage pipe 21 (as shown in the appendix Figure 1 ). When gas storage is not required, the gas locking device 22 can be removed to clean the inside of the gas storage pipe 21.

[0040] Working principle: During operation, rotate the threaded tube 20 so that the threaded tube 20 approaches the interface tube 15, causing the push tube 18 to push the small ball 17 inside the interface tube 15. The two ends of the push tube 18 are connected, enabling the compressed gas to be transmitted through the outlet pipe 14 into the gas storage tube 21 and then to the gas storage cylinder 23 for storage. After the work is completed, reverse-rotate the threaded tube 20 so that the threaded tube 20 moves away from the interface tube 15, causing the push tube 18 to move away from the small ball 17 inside the interface tube 15. At this time, the first spring 16 inside the interface tube 15 releases its elastic potential energy, pushing the small ball 17 to seal one end of the interface tube 15, preventing the compressed gas from leaking. Transmit the hydrogen to be compressed into the inlet pipe 9, start the motor 2, drive the rotation of the disc 3. The rotation of the disc 3 drives the rotation of the rotating block 4 outside it, pulling the connecting rod 5 to move up and down, driving the piston 7 to move inside the pumping tube 6 to compress the hydrogen. When the piston 7 pumps, the air pressure inside the compression chamber 1 also decreases, enabling the ionic liquid inside the cooling box 11 to enter the compression chamber 1 through the liquid inlet pipe 12. As the pressure inside the compression chamber 1 changes, continuous ionic liquid enters, and the liquid outlet pipe 10 at the top of the compression chamber 1 also continuously has ionic liquid seeping back into the cooling box 11. During this process, the ionic liquid cools down the working pumping and pressing device, lubricates the mechanical structure, extends the service life of the mechanical structure, and ensures that the working pumping and pressing device is not affected by high temperature, thus not affecting the compression effect of hydrogen.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art 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 in the protection scope of the present invention.
