[0086] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0087] Since the self-operated air compressor is mainly composed of a boosting system 100, a pressure recovery system I 200, a pressure recovery system II 300, a pressure recovery system III 700, and a pressure re-recovery system 400, the pressure recovery system I 200, pressure recovery system II 300, pressure recovery system III 700, and pressure re-recovery system 400 recover and reuse the gas energy released by the boosting system 100 during discharge, boosting pressure and drawing in air. It can complete gas compression by recovering and utilizing its own energy when the high-pressure gas is depressurized.

[0088] Since the compressed air generated by the self-operated air compressor is stored in an independent high-pressure tank 900, and the boosting system 100 is powered by the air source 60, when the pressure in the high-pressure tank 900 exceeds the original supply pressure and the storage volume exceeds five times the volume required by the air source 60, the pressure supply from the air source 60 can be cut off, and the high-pressure tank 900 can provide pressure to the air source 60, achieving self-sufficiency in pressure. The remaining pressure can be used for external work. The solution to achieve the remaining pressure is that the sum of the actual compression working areas of the recovered compression cylinder 23, the left and right compression cylinders 430, and the boosting compression cylinder 21 at the end of the boosting system 100 must exceed three times the compression working area of ​​the drive cylinder 10 in the pressure-starting assembly 110 supplied by the air source 60. Because the pressure in the intermediate-pressure tank 600 is equal to the pressure in the air source 60, it can also be used by the air source 60 when necessary. Therefore, in environments where electricity or fuel supply is insufficient, the high-pressure tank 900 can replace the air source 60 to provide power, utilizing natural air as an energy supply, thus eliminating dependence on external energy sources and enabling compressed air operations. The amount of residual pressure depends on the number of intake components 130 installed; intake components 130 and corresponding accessories can be added as needed.

[0096] The working principle and operation of this embodiment:

[0097] Open the vent valve of the pressure tank or air pump in the reserved air source 60 to allow the air pressure in the pressure tank or air pump to be delivered to the starting component 110 through the air pressure pipeline. (See the instruction manual appendix.) Figure 2 The air inlet of the solenoid valve 30 of the starting component 110 is pressurized, and the air flows from the inlet to the outlet of the solenoid valve 30, and then through the pipeline to the inlet of the drive cylinder 10, pressurizing the piston inside the drive cylinder 10. The piston of the drive cylinder 10, under pressure, rapidly descends. The piston of the drive cylinder 10 is securely connected to the piston of the compression cylinder 20. During its descent, the piston of the drive cylinder 10 pushes the piston of the compression cylinder 20 downwards simultaneously. The piston rod of the drive cylinder 10 is securely connected to the piston rod of the compression cylinder 20. Therefore, when the piston of the drive cylinder 10 descends, it simultaneously pushes the piston of the compression cylinder 20 downwards. Piston 0 moves downwards; during the downward movement of piston 20, it pushes the gas in front of it, causing the gas volume to shrink, expand, and increase in pressure. The space behind piston 20 during its downward movement is in a vacuum or semi-vacuum state. Under the influence of atmospheric pressure, outside air will force open the one-way valve 40 at the upper air inlet of piston 20 and enter the lower piston 20. When the pressurized gas in piston 20 reaches a certain pressure value, it will force open the one-way valve 40 at the lower air outlet of piston 20 and enter the low-pressure tank 500 through the pipeline.

[0098] When the pistons of drive cylinder 10 and compression cylinder 20 reach their bottom ends, the piston rods of drive cylinder 10 and compression cylinder 20 will trigger the limit switch contacts. Then, the solenoid valve 30 of the starting component 110 will switch the air intake direction, allowing air to enter the lower air intake port of drive cylinder 10, while the upper air intake port will begin to exhaust. The exhaust pressure flows through the exhaust port of solenoid valve 30 of the starting component 110 and through the pipeline to the air intake port of solenoid valve 30 of the boosting component 120. The air pressure flows from the air intake port of solenoid valve 30 of the boosting component 120 to the pipeline tee joint, and through the tee joint to the upper air intake port of boosting drive cylinder 11 and the upper air intake port of boosting compression cylinder 21, respectively, while pressurizing the pistons of boosting drive cylinder 11 and boosting compression cylinder 21.

[0099] Since both the booster drive cylinder 11 and the booster compression cylinder 21 are sealed containers, and the pressure supply direction is consistent with the piston movement direction, the pressure on the surface areas of the upper and lower pistons is equal. However, the pressure generated by the surface areas is not equal, but the pressure on the upper and lower pistons is in the same direction. The two forces become a resultant force, that is, the sum of the pressure on the upper piston and the pressure on the lower piston is the downward force of the lower piston; see the appendix of the instruction manual. Figure 2 The piston diameter of the booster drive cylinder 11 is 125mm, the piston diameter of the booster compression cylinder 21 is 100mm, the air pressure P is 6kPa, and the piston surface area S of the booster drive cylinder 11 is... 上 =122cm 2 The piston surface area S of the booster compression cylinder 21 下 =78.5cm 2The pressure F borne by the piston of the booster drive cylinder 11 上 =PS 上 =6×122=732kg, the pressure F borne by the piston of the booster cylinder 21 下 =PS 下 =6 × 78.5 = 471 kg, F 上 and F 下 The sum is F 上 +F 下 =732+471=1203kg; The pressure discharged from the exhaust port of the compression cylinder 20 is 10kpa, and a total pressure of 785kg is required, with a difference of 418kg between the two forces. The problem is caused by two factors: firstly, the exhaust resistance of the drive cylinder 10, and secondly, the insufficient resistance at the outlet of the compression cylinder 20. In actual operation, 9 kPa is sufficient. When the high-pressure gas generated by the booster compression cylinder 21 reaches a certain pressure value, it will open the one-way valve 40 at the lower exhaust port of the booster compression cylinder 21 and flow through the pipeline to the inlet of the solenoid valve 30 of the intake assembly 130, pressurizing the intake drive cylinder 12 of the intake assembly 130. After being pressurized, the piston of the intake drive cylinder 12 of the intake assembly 130 moves downward, pushing the piston of the intake compression cylinder 22 downward. During the downward movement, the piston of the intake compression cylinder 22 will push the gas blocking it, causing the gas volume to shrink, expand, and increase in pressure. When the pressurized gas in the intake compression cylinder 22 reaches a certain pressure value, it will open the one-way valve 40 at the lower outlet of the intake compression cylinder 22 and enter the low-pressure tank 500 through the pipeline.

[0100] The exhaust from the intake drive cylinder 12 of the intake assembly 130 enters the intake port of the solenoid valve 30 of the next set of booster assemblies 120 through the exhaust port of the solenoid valve 30 of the intake assembly 130. The air pressure is then delivered via a pipeline tee to the upper intake ports of the booster drive cylinder 11 and the booster compression cylinder 21 through the outlet port of the solenoid valve 30 of the booster assembly 120, simultaneously pressurizing the pistons of the booster drive cylinder 11 and the booster compression cylinder 21. This booster assembly 120 repeats the operation of the previous booster assembly 120, and the generated high pressure is delivered to the intake port of the solenoid valve 30 of the next set of intake assemblies 130. This intake assembly 130 repeats the operation of the previous intake assembly 130, and the discharged air pressure is delivered... The pressure is supplied to the next adjacent booster assembly 120. This booster assembly 120 repeats the operation of the previous booster assembly 120, and the generated high pressure is supplied to the next adjacent intake assembly 130. This intake assembly 130 repeats the operation of the previous intake assembly 130. The pressure discharged by the intake drive cylinder 12 is supplied to the solenoid valve 30 of the adjacent booster assembly 120. This group of booster assemblies 120 repeats the operation of the previous booster assembly 120. This cycle of boosting, intake, boosting, and intake is repeated. n groups are set sequentially according to the requirements until the requirements are met. The high pressure of the last group of booster assemblies 120 is recovered to the high pressure tank 900. The above is a single-stroke description of this embodiment.

[0101] The return journey of this embodiment will be described below:

[0102] See the instruction manual appendix Figure 2-7 When the pistons of the drive cylinder 10 and the lower compression cylinder 20 of the starting component 110 reach their bottom ends, the upper and lower piston rods of the drive cylinder 10 and the compression cylinder 20 will touch the limit switch contacts, controlling the solenoid valve 30 to cut off the air intake of the upper air inlet of the drive cylinder 10, while pressurizing the lower air inlet of the drive cylinder 10. After being pressurized, the piston of the drive cylinder 10 quickly moves upward and returns. While moving upward, the piston of the drive cylinder 10 pulls the piston of the compression cylinder 20 upward. During the upward movement, the piston of the compression cylinder 20 pushes the gas in front of it, causing the gas volume to shrink, expand, and increase the pressure. When the pressure of the compression cylinder 20 reaches a certain value, it will open the one-way valve 40 of the upper exhaust port of the compression cylinder 20 and be transported to the low-pressure tank 500 through the pipeline.

[0103] When the pistons of drive cylinder 10 and compression cylinder 20 reach their top positions, the piston rods of drive cylinder 10 and compression cylinder 20 will trigger the limit switch contacts. The limit switch controls the solenoid valve 30 to switch the air intake direction, cutting off the air intake at the lower air intake of drive cylinder 10, while simultaneously filling the upper air intake of drive cylinder 10 and starting to exhaust air from the lower air intake of drive cylinder 10. During the upward movement of the piston of compression cylinder 20, the space behind it is in a vacuum or semi-vacuum state. Under the influence of atmospheric pressure, outside air will force open the one-way valve 40 at the lower air intake of compression cylinder 20 and enter the compression cylinder 20, waiting for the piston to return and compress. The exhaust air from the lower air intake of drive cylinder 10 is delivered to the exhaust port of the solenoid valve 30 of the starting assembly 110. The solenoid valve 30 of the booster assembly 120 receives the input air pressure. Through the solenoid valve 30's inlet and outlet, the input air pressure is delivered via pipelines and tee fittings to the lower inlet of the booster drive cylinder 11 and the lower inlet of the booster compression cylinder 21, respectively, pressurizing the pistons of the booster drive cylinder 11 and the booster compression cylinder 21. A one-way valve 40 is installed at the inlet of the booster compression cylinder 21, ensuring that gas enters the booster compression cylinder 21 only through this valve. When both the booster drive cylinder 11 and the booster compression cylinder 21 are simultaneously pressurized, they move upwards simultaneously. During this upward movement, the piston of the booster compression cylinder 21 pushes down the gas blocking its path, causing it to shrink and expand. Expansion increases pressure; when the pressure inside the booster cylinder 21 reaches a certain value, it will open the one-way valve 40 at the exhaust port of the booster cylinder 21, and the air pressure will be delivered through the pipeline to the inlet of the solenoid valve 30 of the intake assembly 130. The air pressure will then be delivered through the outlet of the solenoid valve 30 and through the pipeline to the inlet of the intake drive cylinder 12 of the intake assembly 130. At this time, the specific air pressure entering which port of the intake drive cylinder 12 is automatically adjusted by the solenoid valve 30. This is because the volume of the booster cylinder 21 of the booster assembly 120 is not equal to the volume of the intake drive cylinder 12 of the intake assembly 130, and the volume of the intake drive cylinder 12 of the intake assembly 130 is larger than the volume of the booster cylinder 21 of the booster assembly 120. The operating frequency of the intake drive cylinder 12 is less than that of the boosting compression cylinder 21 of the boosting assembly 120. The intake drive cylinder 12 of the intake assembly 130 has a waiting time, but for the sake of explanation, the waiting time of the intake drive cylinder 12 of the intake assembly 130 is omitted here, and the operation of the intake assembly 130 is described directly. When the boosting compression cylinder 21 of the boosting assembly 120 delivers high pressure to the air inlet of the solenoid valve 30 of the intake assembly 130, the air pressure is delivered through the air outlet of the solenoid valve 30 of the intake assembly 130 and through the pipeline to the lower air inlet of the intake drive cylinder 12 of the intake assembly 130. After the piston of the intake drive cylinder 12 is compressed, it moves upward quickly, and at the same time drives the piston of the intake compression cylinder 22 to move upward.During the upward movement of the piston in the intake compression cylinder 22, it will push the gas blocking its forward direction, causing the gas volume to shrink, expand, and increase the pressure. When the pressure of the compressed gas reaches a certain pressure value, it will open the one-way valve 40 at the exhaust port of the intake compression cylinder 22 and be transported to the low-pressure tank 500 through the pipeline.

[0104] When the piston of the intake compression cylinder 22 moves upward, the space behind it is in a vacuum or semi-vacuum state. Under the influence of atmospheric pressure, the air outside the intake compression cylinder 22 will be forced open by atmospheric pressure and enter the intake compression cylinder 22 of the intake assembly 130, waiting for the piston to return and push. When the pistons of the intake drive cylinder 12 and the intake compression cylinder 22 of the intake assembly 130 reach the top, the piston rods of the intake drive cylinder 12 and the intake compression cylinder 22 will touch the limit switch contacts. The limit switch controls the solenoid valve 30 to switch the intake direction, that is, close the lower intake port of the intake drive cylinder 12, and open the upper intake port and the lower exhaust port of the intake drive cylinder 12. The exhaust gas from the intake assembly 130 passes through the exhaust port of the solenoid valve 30 and is then transported via pipeline to the intake port of the solenoid valve 30 of the next adjacent booster assembly 120. The input air pressure passes through the outlet port of the solenoid valve 30 of the booster assembly 120 and is then transported via pipeline through a tee to the lower intake ports of the booster drive cylinder 11 and the booster compression cylinder 21 of the booster assembly 120. This booster assembly 120 repeats the operation of the previous booster assembly 120. The high-pressure gas generated by the booster compression cylinder 21 of this booster assembly 120 is then transported via pipeline to the next adjacent intake assembly 130. This intake assembly 130 repeats the operation of the previous intake assembly 130. The exhaust gas from the intake drive cylinder 12 passes through the exhaust port of the solenoid valve 30 of the intake assembly 130 and is then... The air pressure is delivered through pipelines to the inlet of the solenoid valve 30 of the adjacent booster assembly 120. The air pressure is then delivered from the outlet of the solenoid valve 30 through pipelines and a tee to the lower inlets of the booster drive cylinder 11 and the booster compression cylinder 21 of the booster assembly 120, respectively, pressurizing the pistons of the booster drive cylinder 11 and the booster compression cylinder 21. This set of booster assemblies 120 repeats the operation of the previous one. The high-pressure gas discharged from the exhaust port of the booster compression cylinder 21 is delivered through pipelines to the inlet of the solenoid valve 30 of the next adjacent intake assembly 130. This set of intake assemblies 130 repeats the operation of the previous intake assembly 130. The air pressure discharged from the intake drive cylinder 12 is delivered to the next set of intake assemblies 130 through the exhaust port of the solenoid valve 30. The air pressure input through the solenoid valve 30 inlet of the adjacent boosting assembly 120 is delivered via pipeline to the pistons of the boosting drive cylinder 11 and the boosting compression cylinder 21 through the pipeline tee, repeating the action of the previous boosting assembly 120. The high-pressure gas discharged from the exhaust port of the boosting compression cylinder 21 is delivered via pipeline to the solenoid valve 30 inlet of the next adjacent intake assembly 130. This intake assembly 130 repeats the action of the previous intake assembly 130. This cycle of boosting and intake is repeated, and n sets are set according to the requirements until the requirements are met. The high pressure discharged from the exhaust port of the boosting compression cylinder 21 of the last boosting assembly 120 is delivered via pipeline to the high-pressure tank 900.

[0105] The process flow of pressure recovery system I 200, pressure recovery system II 300, and pressure recovery system III 700:

[0106] Instruction manual attached Figure 2 The exhaust of the boost drive cylinder 11 of the boost assembly 120 corresponds to the instructions attached. Figure 3 The air inlets of each solenoid valve 30 of the recovery assembly I 210 arranged sequentially are shown in the instruction manual appendix. Figure 1 The exhaust port of the booster drive cylinder 11 of the booster assembly 120, through its respective solenoid valve 30 exhaust port, transmits air pressure via pipeline to the air inlet of the solenoid valve 30 of its corresponding recovery assembly I 210. The air pressure from the air inlet of the solenoid valve 30 of the recovery assembly I 210, through pipeline and a pipeline tee, is respectively delivered to the air inlets of the recovery I drive cylinder 13 and the recovery I compression cylinder 23 of the recovery assembly I 210. The air pressure enters the recovery I drive cylinder 13 and the recovery I compression cylinder 23 respectively, simultaneously pressurizing the pistons of the recovery I drive cylinder 13 and the recovery I compression cylinder 23. After the pistons are pressurized, the process repeats as described in the appendix to the instruction manual. Figure 2 The operation of the intermediate pressure boosting component 120 recovers the high-pressure gas generated by the compression cylinder 23 and transports it to the intermediate pressure tank 600 through pipelines.

[0107] The air pressure discharged from the drive cylinder 13 of recovery component I is discharged through the exhaust port of the solenoid valve 30 of recovery component I 210 to the air inlet of the solenoid valve 30 of the respective pressure recovery system II 300. See the instruction manual appendix. Figure 4 The air pressure enters the air inlet of the recovery II drive cylinder 14 and the recovery II compression cylinder 24 of the recovery component II 310 through the solenoid valve 30 outlet, and pressurizes the pistons of the recovery II drive cylinder 14 and the recovery II compression cylinder 24. The pressure recovery system II 300 repeats the action of the pressure recovery system I 200. The high pressure gas generated by the recovery II compression cylinder 24 is transported to the medium pressure tank II 610 through the pipeline.

[0108] The exhaust gas from the recovery II drive cylinder 14 of the recovery component II 310 is transported to the recovery tank 800 via pipeline through the exhaust port of the solenoid valve 30 of the recovery component II 310.

[0109] The air pressure from the medium-pressure tank II 610 is delivered via pipeline to the air inlet of the solenoid valve 30 of the end recovery component I 210 of the pressure recovery system I 200. See the instruction manual appendix. Figure 3The air pressure is delivered from the outlet of the solenoid valve 30 of the recovery assembly I 210 through pipelines and pipeline tees to the inlets of the recovery I drive cylinder 13 and the recovery I compression cylinder 23 of the recovery assembly I 210, respectively, to pressurize the pistons of the recovery I drive cylinder 13 and the recovery I compression cylinder 23. The pressurized pistons begin to move. The recovery assembly I 210 repeats the operation of the aforementioned booster assembly 120. The high-pressure gas discharged from the exhaust port of the recovery I compression cylinder 23 of the recovery assembly I 210 is delivered to the high-pressure tank 900 through pipelines.

[0110] The exhaust gas from the recovery I drive cylinder 13 of the end recovery component I 210 is delivered via pipeline from the exhaust port of the solenoid valve 30 of the recovery component I 210 to the inlet port of the solenoid valve 30 of the recovery component II 310 at the end of the pressure recovery system II 300. (See the attached instruction manual.) Figure 4 The air pressure is delivered through the outlet of the solenoid valve 30 of the recovery assembly II 310, and then via the pipeline tee to the inlet of the recovery II drive cylinder 14 and the recovery II compression cylinder 24 of the recovery assembly II 310, pressurizing the pistons of the recovery II drive cylinder 14 and the recovery II compression cylinder 24 of the recovery assembly II 310. See the appendix to the instruction manual. Figure 4 The recovery component II 310 repeats the operation of the aforementioned pressurization component 120. The air pressure discharged from the exhaust port of the recovery II compression cylinder 24 is transported to the intermediate pressure tank II 610 through the pipeline for repressurization.

[0111] The air pressure discharged from the recovery II drive cylinder 14 of the recovery component II 310 is transported to the recovery tank 800 through the exhaust port of the solenoid valve 30 of the recovery component II 310 via a pipeline connection, awaiting pressurization processing.

[0112] See the instruction manual appendix Figure 6 The air pressure in the recovery tank 800 is delivered to the outlet of the solenoid valve 30 of the pressure recovery system Ⅲ 700 through pipelines. The air pressure in the recovery tank 800 is then delivered to the inlets of the recovery Ⅲ drive cylinder 15 and the recovery Ⅲ compression cylinder 25 of the pressure recovery system Ⅲ 700, respectively, to pressurize the recovery Ⅲ drive cylinder 15 and the recovery Ⅲ compression cylinder 25. The pressure recovery system Ⅲ 700 repeats the action of the pressurization component 120. The exhaust gas from the recovery Ⅲ drive cylinder 15 is delivered to the inlet of the solenoid valve 30 of the pressure recovery system 400 through the exhaust port of the matching solenoid valve 30, and then through pipelines and pipeline tees. The high-pressure gas discharged from the recovery Ⅲ compression cylinder 25 is delivered to the high-pressure tank 900.

[0113] The process flow of the pressure recovery system 400:

[0114] See the instruction manual appendix Figure 5The low-pressure gas from the low-pressure tank 500 and the exhaust gas from the recovery III drive cylinder 15 are delivered to the inlet of the solenoid valve 30 of the upper drive cylinder 410 via pipelines and pipeline tee joints. From the outlet of the solenoid valve 30, the gas is delivered via pipelines and tee joints to the inlets of the upper drive cylinder 410 and the left and right compression cylinders 430, respectively, pressurizing the pistons of the upper drive cylinder 410 and the left and right compression cylinders 430. After being pressurized, the pistons begin to move, and the upper drive cylinder 410 and the left and right compression cylinders 430 repeat the operation of the recovery component II 310. (See the attached instruction manual.) Figure 4 The exhaust gas from the upper drive cylinder 410 is transported to the intermediate pressure tank II 610 via pipeline through the exhaust port of the matching solenoid valve 30; the high pressure generated by the left and right compression cylinders 430 is transported to the high pressure tank 900 via pipeline through the one-way valve 40; considering that it is difficult to complete this set of actions according to the air pressure input by the upper drive cylinder 410 and the left and right compression cylinders 430, an assist cylinder 420 is added in this embodiment; the piston rod of the assist cylinder 420 is fastened to the piston rods of the upper drive cylinder 410 and the left and right compression cylinders 430 together via the connecting plate 440, and they move in the same direction; the air pressure of the assist cylinder 420 is supplied by the intermediate pressure tank I 600. The piston diameter of the booster cylinder 420 is larger than that of the upper drive cylinder 410. The solenoid valve 30 of the booster cylinder 420 and the solenoid valve 30 of the upper drive cylinder 410 are synchronized and in the same direction. Therefore, the upper drive cylinder 410, in relation to the booster cylinder 420, is both the drive cylinder for the left and right compression cylinders 430 and the pressure booster cylinder for the booster cylinder 420, and has a dual function. The booster cylinder 420 can help the upper drive cylinder 410 complete the whole set of actions. The air pressure discharged by the booster cylinder 420 is transported to the recovery tank 800 through the exhaust port of the solenoid valve 30 of the booster cylinder 420 via pipeline, and then circulated and pressurized, realizing the closed operation of the whole process, with no leakage and no pressure discharge.
