Description

Technical Field

[0001] The present invention belongs to the technical field of hydrogen compression, and particularly relates to an efficient hydrogen compression device. Background Art

[0002] Existing hydrogen compression devices are key equipment for pressurizing hydrogen to meet storage, transportation, and application requirements. Their core function is to increase the pressure of hydrogen through mechanical or power means, thereby reducing volume and increasing energy density, providing support for all links of the hydrogen energy industry chain. Commonly used hydrogen compression devices are usually piston compressors and diaphragm compressors. Among them, piston compressors are only suitable for medium and high-pressure scenarios, while diaphragm compressors use diaphragms to reciprocate under hydraulic drive to compress gases, with good sealing performance and are suitable for compressing high-purity hydrogen.

[0003] A hydrogen diaphragm compressor with the patent publication number CN214998137U in the prior art includes a diaphragm compressor body and a base. The diaphragm compressor body is fixed in the middle of the top surface of the base, and a protective cover body is detachably fixed around the diaphragm compressor body on the base through a quick-release component; the quick-release component specifically is: vertical insertion plates are fixedly arranged along the longitudinal direction on both bottom surfaces of the protective cover body, and a plurality of limiting holes are arranged along the transverse direction on the insertion plates. The beneficial effects are as follows: The utility model detachably fixes the protective cover body on the top surface of the base through the quick-release component and covers the diaphragm compressor body, so as to isolate and protect the diaphragm compressor body, replacing the setting method in which the diaphragm compressor body is directly exposed in the use site, avoiding accidental impact and damage to the diaphragm compressor body resulting in shutdown, and being beneficial to improving the use stability of the diaphragm compressor body.

[0004] The above-mentioned and existing diaphragm compressors all involve the problem of diaphragm life. When the diaphragm is damaged, the hydraulic oil on one side of the diaphragm will penetrate and leak into the gas compressed on the other side of the diaphragm, and it is often impossible to detect and cut off the operation of the device in time, resulting in the hydraulic oil falling into the intake and exhaust valves, causing blockage, being inconvenient to clean, and the oil-gas mixture also needs to be separated, greatly increasing the labor intensity of operators. Summary of the Invention

The locking rod is movably installed inside the second pneumatic cylinder, and the end of the locking rod is designed with an inclined surface. The first pneumatic cylinder is connected to the inner cavity of the second pneumatic cylinder through the ventilation pipe. The bottom side inside the separation cylinder is communicated with the oil storage cavity at the bottom end of the driving device through a conveying valve pipe.

[0021] The present invention also provides an operation method for an efficient hydrogen compression device, and the operation steps are as follows:

[0022] S1. First, start the first one-way valve to unidirectionally introduce the hydraulic oil in the oil storage chamber at the bottom of the driving device into the outer cavity of the compression housing, and part of the hydraulic oil unidirectionally enters the inner cavity of the compression diaphragm through the second one-way valve;

[0023] S2. Subsequently, start the driving device to drive the piston member to expand and contract, so that the hydraulic oil drives the compression diaphragm to deform, so that a force is generated in the inner cavity of the sealing cover to introduce hydrogen into the interior through the intake valve for compression and then discharge it through the exhaust valve;

[0024] S3. Then, when the outer side of the compression diaphragm ruptures, the hydraulic oil will leak out. Since the gravity of the hydraulic oil is greater than that of hydrogen, it will accumulate at the top of one side of the baffle plate at the bottom of the inner cavity of the sealing cover. When the oil inside the compression diaphragm slowly leaks out, the elastic force of the first elastic member will be released, thereby pushing the first piston rod to move inward, so that the gas in the inner cavity of the air cylinder pushes the valve flap to open and enter the pneumatic ring pipe through the exhaust pipe, thereby pushing the movable ring plate to move outward, so as to drive the telescopic cylinder to move and compress the gas in one end inner cavity of the pressure alarm, fix the telescopic cylinder at a certain position through the positioning ring and apply a preset pressure alarm value to the interior of the pressure alarm, so that the pressure alarm sounds and the overall operation of the device stops;

[0025] S4. After that, since the movable ring plate moves outward, it will push the top block to drive and push the outer inclined surface of the sealing baffle plate, so that the sealing baffle plate slides along the surface of the limiting rod, so as to block and seal one side of the exhaust valve and the intake valve to prevent the hydraulic oil from entering;

[0026] S5. At the same time, the movement of the movable ring plate will push the transmission piston rod to slide in the inner cavity of the first hydraulic cylinder and extrude the inner cavity hydraulic oil into the oil through-flow groove, so that the hydraulic oil in the oil through-flow groove enters the second hydraulic cylinder, thereby pushing the baffle plate to move to one side, which can release the block on the bottom end of the sealing cover, and the baffle plate will push the first pneumatic piston rod to slide in the inner cavity of the first pneumatic cylinder, so as to push the gas in the inner cavity of the first pneumatic cylinder to be introduced into the second pneumatic cylinder through the trachea, and further push the locking rod to move to one side;

[0027] S6. Finally, when the hydraulic oil at the bottom of the sealing cover falls to the bottommost part of the movable disk, all the hydraulic oil will be stored at the top of the movable disk in the inner cavity of the separation cylinder. When the movable disk moves downward, one side will squeeze the locking rod to move to the other side first and then release and reset so that the end part inserts into the inner part of one side of the movable disk to fix the movable disk, and the support rod just seals the top of the separation cylinder to realize oil-gas separation. Finally, the hydraulic oil is pumped back to the oil storage chamber at the bottom of the driving device through the conveying valve pipe to realize the recovery of the hydraulic oil.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] (1) Through the above technical solution, by setting a determination mechanism and an alarm mechanism, when the outer part of the compression diaphragm ruptures, a certain amount of hydraulic oil inside will enter the inner cavity of the sealing cover. The reduction of the hydraulic oil will release a part of the determination mechanism, which will then push the internal gas into the alarm mechanism. The alarm part of the alarm mechanism will sense the preset pressure alarm value and then issue an alarm, so as to alarm the operator in time that one side of the compression diaphragm is ruptured and it is necessary to stop the machine for maintenance in time for subsequent oil-gas separation operations, greatly reducing the labor intensity of the operator.

[0030] (2) By setting a top block and a sealing baffle, when gas enters the inner cavity on one side of the alarm mechanism, it will synchronously push the top block to move, and then push the inclined surface at the outer end of the sealing baffle, so as to drive the sealing baffle to slide along the surface of the limiting rod to one side until it completely blocks and seals one side of the exhaust valve and the intake valve. At this time, the hydraulic oil leaking from the inside of the compression diaphragm can be prevented from entering the exhaust valve and the intake valve, reducing the cleaning steps.

[0031] (3) By setting a second sealing component, a separation component and a fixing component, when the air pressure in the inner cavity on one side of the alarm mechanism increases, it will push the bottom part of the second sealing component, thereby driving the top part of the second sealing component to release the sealing and shielding effect on the bottom of the inner cavity of the driving device. Then, the hydraulic oil leaking from the compression diaphragm will enter the inner bottom of the sealing cover through the compression diaphragm and fall into the separation component. When the separation component is full, it will seal the top to prevent gas from entering, thereby achieving the purpose of oil-gas separation. The hydraulic oil can be pumped back to the oil storage cavity at the bottom of the driving device through the conveying valve pipe to avoid waste of hydraulic oil. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] It should be noted that the terms "upper", "lower", "left", "right", "top", "bottom", "inner", "outer", etc. indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0045] It should be understood that in the description of the invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "connected" should be understood in a broad sense.

[0046] Embodiment 1: As Figures 1 to 10 shown, Embodiment 1 of the present invention provides an efficient hydrogen compression device, including a support platform 1, and further including: a driving device 2, which is arranged in the middle of the top end of the support platform 1; a compression sleeve 3, which is arranged at both ends of the driving device 2, and a sealing cover 4 is arranged at the outer end of the compression sleeve 3; a compression mechanism 5, which is arranged inside the compression sleeve 3 and the sealing cover 4; a determination mechanism 6, which is arranged inside the outer end of the compression mechanism 5; wherein, the determination mechanism 6 includes a filling body 601 arranged inside the outer end of the compression mechanism 5 near the sealing cover 4, a second one-way valve 602 is arranged in the middle of the filling body 601, an air cylinder 603 is arranged inside the second one-way valve 602, a first piston rod 604 is movably installed inside the air cylinder 603, the first piston rod 604 is connected to a part of the outer end of the compression mechanism 5, the first piston rod 604 is elastically connected to the inner cavity of the air cylinder 603 through a first elastic member 605, and an alarm mechanism 7 located outside the filling body 601 is arranged on the surface of the compression sleeve 3.

[0047] When a part on one side of the compression mechanism 5 is damaged and leaks oil, the elastic force of the first elastic member 605 will be slowly released, thereby pushing the first piston rod 604 to drive the gas in the inner cavity of the air cylinder 603 into the alarm mechanism 7, and the alarm part of the alarm mechanism 7 senses a specified pressure value, and thus an alarm will be issued to remind the operator.

[0048] As Figure 2 shown, an oil storage cavity is arranged at the bottom of the driving device 2, and the compression mechanism 5 includes a piston member 501, a compression diaphragm 502, an exhaust valve 503, an intake valve 504, and a first one-way valve 505;

[0049] The piston member 501 is movably installed inside the compression sleeve 3, and the inner end of the piston member 501 is hinged to the outer end of the driving device 2. The compression diaphragm 502 is arranged at the end of the driving device 2 and is located outside the determination mechanism 6. The exhaust valve 503 and the intake valve 504 are respectively arranged above and below the inside of the compression sleeve 3. The inner cavity of the outer end of the compression sleeve 3 is communicated with the oil storage cavity at the bottom of the driving device 2 through the first one-way valve 505.

[0050] Adopting the above solution: By providing the piston member 501, when the driving device 2 operates, it will drive the piston member 501 to expand and contract towards or away from each other, and then can push the hydraulic oil in the outer cavity of the compression sleeve 3 to squeeze the compression diaphragm 502 as a whole to compress the hydrogen inside the compression sleeve 3.

[0051] As Figure 3 and Figure 4 shown, the alarm mechanism 7 includes a pneumatic ring pipe 701, a movable ring plate 702, a pressure alarm 703, a telescopic cylinder 704, a positioning ring 705, an exhaust pipe 706 and a valve flap 707;

[0052] The pneumatic ring pipe 701 is arranged on the surface of the compression sleeve 3, and the pneumatic ring pipe 701 is located outside the filling body 601. The movable ring plate 702 is movably installed in the inner cavity of the pneumatic ring pipe 701. The pressure alarm 703 is arranged in the middle on the outer side of the top end of the pneumatic ring pipe 701. The telescopic cylinder 704 is arranged in the middle on the outer side of the top end of the movable ring plate 702, and the outer end of the telescopic cylinder 704 extends into the inner cavity of the pressure alarm 703. The positioning ring 705 is arranged in the inner cavity of the pressure alarm 703, and the positioning ring 705 is located outside the telescopic cylinder 704.

[0053] Adopting the above solution: By providing the positioning ring 705, when gas enters the inner side of the inner cavity of the pneumatic ring pipe 701, it will push the movable ring plate 702 to drive the telescopic cylinder 704 to move outward until it is blocked by the positioning ring 705 and stops moving, thereby realizing a specified pressure value for the pressure alarm 703, and thus releasing the pressure alarm 703 to successfully give an alarm.

[0054] As Figure 3 shown, the inner cavity of the telescopic cylinder 704 is provided with gas.

[0055] Adopting the above solution: Since the gas can be compressed and will be released when decompressed, it can smoothly drive the telescopic cylinder 704 to expand and contract, so that when the positioning ring 705 blocks the telescopic cylinder 704, the pressure alarm 703 and the telescopic cylinder 704 as a whole can still move.

[0056] As Figures 7 to 9 shown, a first sealing assembly 8 is arranged inside the sealing cover 4 between the compression diaphragm 502 and the exhaust valve 503. The first sealing assembly 8 includes a top block 801, a sealing baffle 802 and a limiting rod 803;

[0057] The top block 801 is fixedly installed in the middle of the outer side of the rear end of the movable ring plate 702. The sealing baffle 802 is movably installed inside the sealing cover 4, and the sealing baffle 802 is located between the inner cavity of the sealing cover 4 and the exhaust valve 503. The limiting rod 803 is arranged inside the sealing cover 4 and is slidably connected to the end of the sealing baffle 802. The sealing baffle 802 is elastically connected to the inner wall of the sealing cover 4 through the second elastic member 804, and the outer end of the sealing baffle 802 is provided with an inclined surface.

[0058] Adopting the above scheme: when the movable ring plate 702 moves outward, it will drive the end of the top block 801 to squeeze and push the inclined surface of the sealing baffle 802, causing the sealing baffle 802 to move, thereby covering one side of the exhaust valve 503 and the intake valve 504.

[0059] As Figure 7 shown, the inner groove at the end of the sealing baffle 802 has the same size as the inner cavities of the exhaust valve 503 and the intake valve 504.

[0060] Adopting the above scheme: when the second elastic member 804 pushes the sealing baffle 802 to move and fix, the inner side of the end of the sealing baffle 802 will be aligned with the inner cavities of the exhaust valve 503 and the intake valve 504, allowing the gas to pass through smoothly.

[0061] As Figures 3 to 5 shown, a second sealing assembly 9 is arranged inside the compression sleeve 3 and is located below the compression diaphragm 502. The second sealing assembly 9 includes a first hydraulic cylinder 901, a transmission piston rod 902, a second hydraulic cylinder 903, a shielding baffle 904 and an oil passage 905;

[0062] The first hydraulic cylinder 901 is fixedly installed inside the compression sleeve 3, and the first hydraulic cylinder 901 is located outside one end of the bottom of the pneumatic ring pipe 701. The transmission piston rod 902 is movably installed inside the first hydraulic cylinder 901. The second hydraulic cylinder 903 is arranged inside the sealing cover 4 and is located below the filling body 601. The shielding baffle 904 is arranged inside the second hydraulic cylinder 903, and one end of the shielding baffle 904 extends into the compression sleeve 3. The first hydraulic cylinder 901 is communicated with the inner cavity of the second hydraulic cylinder 903 through the oil passage 905.

[0063] Adopting the above scheme: by providing the shielding baffle 904, when the movable ring plate 702 moves, it will push the transmission piston rod 902 to squeeze and push the hydraulic oil in the inner cavity of the first hydraulic cylinder 901 into the oil passage 905. The excess hydraulic oil in the oil passage 905 will enter the second hydraulic cylinder 903 to push the shielding baffle 904 to move to one side. At the same time, it will squeeze the gas outside the inner cavity of the second hydraulic cylinder 903. When the shielding baffle 904 moves and fixes to one side, it will block and seal the bottom of the inner cavity formed between the compression sleeve 3 and the sealing cover 4.

[0064] As Figure 5 andFigure 6 As shown in the figure, a separation component 11 is provided at the bottom of the outer end of the compression sleeve 3. The separation component 11 includes a separation cylinder 1101, a movable disk 1102, a support rod 1103, a third elastic member 1104, and a sealing stop rod 1105;

[0065] The separation cylinder 1101 is fixedly installed at the bottom of the outer end of the compression sleeve 3. The movable disk 1102 is movably installed in the inner cavity of the separation cylinder 1101. The support rod 1103 is arranged in the middle of the bottom end of the movable disk 1102, and the bottom end of the support rod 1103 is elastically connected to the inner wall of the support platform 1 through the third elastic member 1104. The sealing stop rod 1105 is arranged between the top of the movable disk 1102 and below the shielding plate 904.

[0066] With the above scheme: By providing the third elastic member 1104, due to the elastic force of the third elastic member 1104, it will push the support rod 1103 to drive the overall upward movement of the movable disk 1102.

[0067] As Figures 4 to 6 shown, fixing components 12 are respectively provided inside the sealing cover 4 and the separation cylinder 1101, which are located outside the shielding plate 904 and on one side of the bottom end of the separation cylinder 1101. The fixing components 12 include a first pneumatic cylinder 1201, a first pneumatic piston rod 1202, a second pneumatic cylinder 1203, a locking rod 1204, and a ventilation pipe 1205;

[0068] The first pneumatic cylinder 1201 is arranged inside the sealing cover 4 and is located outside the shielding plate 904. The first pneumatic piston rod 1202 is movably installed in the inner cavity of the first pneumatic cylinder 1201. The second pneumatic cylinder 1203 is arranged outside the bottom end of the separation cylinder 1101. The locking rod 1204 is movably installed in the inner cavity of the second pneumatic cylinder 1203, and the end of the locking rod 1204 is designed with an inclined surface. The first pneumatic cylinder 1201 is connected to the inner cavity of the second pneumatic cylinder 1203 through the ventilation pipe 1205. The inner bottom of the separation cylinder 1101 is communicated with the oil storage cavity at the bottom end of the driving device 2 through the conveying valve pipe 10.

[0069] With the above scheme: By providing the locking rod 1204, when the shielding plate 904 moves to one side, it will push the first pneumatic piston rod 1202 to squeeze and push the gas in the first pneumatic cylinder 1201 into the ventilation pipe 1205. The extra gas in the inner cavity of the ventilation pipe 1205 enters the second pneumatic cylinder 1203 to push the locking rod 1204 to move to one side. Then when the movable disk 1102 moves downward, it will first squeeze the inclined surface of the locking rod 1204 to push the locking rod 1204 to reset and compress the gas in the second pneumatic cylinder 1203. Until the movable disk 1102 moves to the bottommost position, the gas in the second pneumatic cylinder 1203 will be released to push the locking rod 1204 to one side so that the end portion inserts into the movable disk 1102 to fix the movable disk 1102.

[0070] The present invention also provides an operation method for an efficient hydrogen compression device, and the operation steps are as follows:

[0071] S1. First, start the first one-way valve 505 to unidirectionally introduce the hydraulic oil in the oil storage chamber at the bottom of the driving device 2 into the outer cavity of the compression housing 3, and part of the hydraulic oil unidirectionally enters the inner cavity of the compression diaphragm 502 through the second one-way valve 602;

[0072] S2. Subsequently, start the driving device 2 to drive the piston member 501 to expand and contract, so that the hydraulic oil drives the compression diaphragm 502 to deform, so that a force is generated in the inner cavity of the sealing cover 4 to introduce hydrogen into the interior through the intake valve 504 for compression and then discharge it through the exhaust valve 503;

[0073] S3. Then, when the outer side of the compression diaphragm 502 ruptures, the hydraulic oil will leak out. Since the gravity of the hydraulic oil is greater than that of hydrogen, it will accumulate on the top of one side of the baffle 904 at the bottom of the inner cavity of the sealing cover 4. When the oil inside the compression diaphragm 502 slowly leaks out, the elastic force of the first elastic member 605 will be released, thereby pushing the first piston rod 604 to move inward, so that the gas in the inner cavity of the air cylinder 603 pushes the valve flap 707 to open and enters the inner part of the pneumatic ring pipe 701 through the exhaust pipe 706, thereby pushing the movable ring plate 702 to move outward, so as to drive the telescopic cylinder 704 to move and compress the gas in one end inner cavity of the pressure alarm 703, fix the telescopic cylinder 704 at a certain position through the positioning ring 705 and apply a preset pressure alarm value to the interior of the pressure alarm 703, so that the pressure alarm 703 issues an alarm and stops the overall operation of the device;

[0074] S4. After that, since the movable ring plate 702 moves outward, it will push the top block 801 to drive and push the outer inclined surface of the sealing baffle 802, so that the sealing baffle 802 slides along the surface of the limiting rod 803, so as to block and seal one side of the exhaust valve 503 and the intake valve 504 to prevent the hydraulic oil from entering;

[0075] S5. At the same time, the movement of the movable ring plate 702 will push the transmission piston rod 902 to slide in the inner cavity of the first hydraulic cylinder 901 and extrude the inner cavity hydraulic oil into the oil through-flow groove 905, so that the hydraulic oil in the oil through-flow groove 905 enters the second hydraulic cylinder 903, thereby pushing the baffle 904 to move to one side, which can release the occlusion of the bottom end of the sealing cover 4, and the baffle 904 will push the first pneumatic piston rod 1202 to slide in the inner cavity of the first pneumatic cylinder 1201, so as to push the gas in the inner cavity of the first pneumatic cylinder 1201 to be introduced into the second pneumatic cylinder 1203 through the ventilation pipe 1205, and further push the locking rod 1204 to move to one side;

[0076] S6. Finally, when the hydraulic oil at the bottom of the sealing cover 4 falls into the bottommost part downward of the movable disk 1102, all the hydraulic oil will be stored at the top of the movable disk 1102 in the inner cavity of the separation cylinder 1101. When the movable disk 1102 moves downward, one side will squeeze the locking rod 1204 to move to the other side first and then release and reset, so that the end part is inserted into the inside of one side of the movable disk 1102 to fix the movable disk 1102. And the support rod 1103 just seals the top of the separation cylinder 1101 to realize oil-gas separation. Finally, the hydraulic oil is pumped back to the oil storage cavity at the bottom of the driving device 2 through the conveying valve pipe 10 to realize the recovery of the hydraulic oil.

10. The operating method of the high-efficiency hydrogen compression device according to any one of claims 1-9, characterized in that, The steps of the operation method are as follows: S1. First, start the first one-way valve (505) to unidirectionally introduce the hydraulic oil in the oil storage cavity at the bottom of the driving device (2) into the outer inner cavity of the compression sleeve (3), and part of the hydraulic oil unidirectionally enters the inner cavity of the compression diaphragm (502) through the second one-way valve (602). S2. Subsequently, start the driving device (2) to drive the piston member (501) to expand and contract, so that the hydraulic oil drives the compression diaphragm (502) to deform, so that a force is generated in the inner cavity of the sealing cover (4) to introduce hydrogen into the inside through the intake valve (504) for compression and then discharge it through the exhaust valve (503). S3. Then, when the outer side of the compression diaphragm (502) ruptures, the hydraulic oil will leak out. Since the gravity of the hydraulic oil is greater than that of hydrogen, it will accumulate on the top of one side of the baffle (904) at the bottom of the inner cavity of the sealing cover (4). When the oil inside the compression diaphragm (502) slowly leaks out, the elastic force of the first elastic member (605) will be released, thereby pushing the first piston rod (604) to move inward, so that the gas in the inner cavity of the air cylinder (603) pushes the valve flap (707) to open and enter the inside of the pneumatic ring pipe (701) through the exhaust pipe (706), thereby pushing the movable ring plate (702) to move outward, so as to drive the telescopic cylinder (704) to move and compress the gas in one end of the inner cavity of the pressure alarm (703), fix the telescopic cylinder (704) at a certain position through the positioning ring (705) and apply a preset pressure alarm value to the inside of the pressure alarm (703), so that the pressure alarm (703) issues an alarm and stops the overall operation of the device. After S4, since the movable ring plate (702) moves outward, it will push the top block (801) to drive and push the outer end slope of the sealing baffle (802), so that the sealing baffle (802) slides along the surface of the limit rod (803), in order to shield and seal one side of the exhaust valve (503) and the intake valve (504), and prevent hydraulic oil from entering; In S5, at the same time, the movement of the movable ring plate (702) will push the transmission piston rod (902) to slide in the inner cavity of the first hydraulic cylinder (901) and squeeze the hydraulic oil in the inner cavity into the oil passage (905), so that the hydraulic oil in the oil passage (905) enters the inside of the second hydraulic cylinder (903), thereby pushing the shielding plate (904) to move to one side, which can release the shielding of the bottom end of the sealing cover (4), and the shielding plate (904) will push the first pneumatic piston rod (1202) to slide in the inner cavity of the first pneumatic cylinder (1201), so as to push the gas in the inner cavity of the first pneumatic cylinder (1201) to be introduced into the inside of the second pneumatic cylinder (1203) through the ventilation pipe (1205), and then push the locking rod (1204) to move to one side; In S6, finally, when the hydraulic oil at the bottom of the sealing cover (4) falls to the bottommost part when the movable disk (1102) moves downward, all the hydraulic oil will be stored at the top of the movable disk (1102) in the inner cavity of the separation cylinder (1101). When the movable disk (1102) moves downward, one side will squeeze the locking rod (1204) to move to the other side first and then release and reset, so that the end part is inserted into the inside of one side of the movable disk (1102) to fix the movable disk (1102), and the support rod (1103) just seals the top of the separation cylinder (1101) to achieve oil-gas separation. Finally, the hydraulic oil is pumped back to the oil storage cavity at the bottom of the driving device (2) through the conveying valve pipe (10) to realize the recovery of the hydraulic oil.
