[0002] The hydraulic power station provides continuous power for hydraulic equipment and is used to drive various handheld hydraulic tools with different functions. That is, the hydraulic oil that meets the requirements of the hydraulic system is used as the medium, and the medium that meets the required flow and pressure is pumped out by the original power through the pump for use by the hydraulic system. At present, new energy hydraulic power stations that use renewable energy as a power source are gradually becoming popular, usually to reduce dependence on fossil fuels, reduce operating costs, and reduce environmental pollution.

[0003] The oil suction filter is an important component of the hydraulic power station. It is located in the oil tank, at the oil suction port of the oil pump, to ensure preliminary filtration of the oil before it enters the pump, filtering out impurities and particulate matter in the oil to protect the hydraulic pump and the entire system from pollution damage.

[0004] The impurities passing through the oil suction filter will be blocked by the filter cartridge, but these impurities will concentrate on the outer surface of the filter cartridge, affecting the normal filtering effect of the filter cartridge.

The oil in the oil passage chamber will enter the collecting chamber with impurities and will be blocked by the filter plate. The baffle is then driven back by the pushing component to block the passage. After the residual oil in the collecting chamber is pumped away, the impurities on the filter plate can be cleaned through the cleaning pipe. The impurities can be cleaned conveniently without disassembling the oil tank and the filter box, which eliminates the complicated work process and saves time and effort. It also prevents the impurities from being in the oil passage chamber for a long time and causing blockage to the filter cartridge, thereby better protecting the filter cartridge and improving its subsequent filtering effect.

[0034] 3. In this solution, the push plate in the push component moves while pushing the impurities on the filter plate, so that the impurities on the inner side of the filter plate move outward, which makes it easier to clean the impurities on the filter plate later, and the operation is simple and convenient.

[0035] 4. In this scheme, when the auxiliary oil pump sucks oil through the oil suction pipe, the oil will impact multiple scrapers, causing the scrapers and the rings to rotate. The scrapers will scrape and push the impurities at the bottom of the oil chamber, and finally push the impurities to the opening position and enter the collection chamber, further improving the cleaning effect of the impurities in the oil chamber, and having strong practicality.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] See also Figure 1-8 , an anti-clogging hydraulic power station, including a power station body 1 and an oil tank 2 arranged thereon, and also including: a filter box 3, which is arranged in the oil tank 2, and a connecting pipe 4 is provided on the filter box 3, and the connecting pipe 4 is connected to the oil suction port of the main oil pump in the oil tank 2, and an oil passage chamber 6 is opened in the filter box 3; an oil inlet pipe 7 is arranged on the filter box 3 and communicated with the oil passage chamber 6, and a paddle 8 is arranged in the oil inlet pipe 7; a filter cartridge 9 is arranged in the oil passage chamber 6, and one end of the connecting pipe 4 passes through the filter box 3 and is connected with the top of the filter cartridge 9; a scraper ring 10 is slidably sleeved on the outer surface of the filter cartridge 9, and a transmission mechanism 5 for driving the scraper ring 10 to move up and down is provided on the filter box 3.

[0048] When in use, the main oil pump in the oil tank 2 is started to suck oil through the connecting pipe 4, and the oil in the oil tank 2 enters the oil passage chamber 6 of the filter box 3 from the oil inlet pipe 7. After being filtered by the filter cartridge 9, the oil enters the interior of the filter cartridge 9 and is finally sucked away through the connecting pipe 4. Impurities will remain in the oil passage chamber 6, thus completing the filtering operation of the oil.

[0049] When the oil enters the oil chamber 6 from the oil inlet pipe 7, the oil will generate an impact force on the paddle 8, thereby pushing the paddle 8 to rotate, and then the transmission mechanism 5 can drive the scraper ring 10 to move back and forth along the filter cartridge 9, so that the scraper ring 10 can scrape the outer surface of the filter cartridge 9 up and down, and the impurities on the surface of the filter cartridge 9 can be scraped off. During the continuous filtering use of the filter cartridge 9, the scraper ring 10 will move back and forth up and down to scrape off the impurities, avoiding the current situation where impurities are concentrated on the surface of the filter cartridge 9 when it is in use, which can ensure the normal filtering quality and effect of the filter cartridge 9, and also prevent the situation where impurities accumulate for a long time and block the filter holes of the filter cartridge 9. While significantly improving the service life of the filter cartridge 9, it can also improve the oil absorption efficiency, ensure the normal operation of the subsequently connected hydraulic tools, reduce the frequency of cleaning and replacement of the filter cartridge 9, save time and effort, and greatly save costs. It has good use effect and strong practicality, and can be widely promoted and used.

[0050] In this embodiment, preferably, please refer to Figure 3-5 The filter box 3 is provided with a transmission chamber 11, and the transmission mechanism 5 includes: a screw rod 51, which is rotatably arranged on the inner wall of the oil chamber 6, and a nut seat 52 is threadedly connected to the screw rod 51, and the nut seat 52 is connected to the scraper ring 10, and the lower end of the screw rod 51 extends into the transmission chamber 11; a linkage component 53 is arranged in the transmission chamber 11, and is used to drive the screw rod 51 to rotate back and forth. After the oil drives the blade 8 to rotate, the linkage component 53 will drive the screw rod 51 to rotate back and forth, and the rotation of the screw rod 51 will drive the nut seat 52 threadedly connected to it to move up and down, and the nut seat 52 will drive the scraper ring 10 to move up and down along the filter cartridge 9, so that the scraper ring 10 will scrape the impurities on the outer wall of the filter cartridge 9 repeatedly up and down.

[0051] A vertical rod 25 is provided between the upper and lower walls of the oil passage chamber 6, and a moving block 26 is slidably sleeved on the vertical rod 25, and the moving block 26 is connected to the scraper ring 10. When the scraper ring 10 moves up and down, it drives the moving block 26 to slide up and down along the vertical rod 25. Through the cooperation of the moving block 26, the stability and smoothness of the movement of the scraper ring 10 can be improved.

[0052] In this embodiment, preferably, please refer to Figure 5-7 The linkage component 53 includes: a linkage rod 531 and a transmission rod 534, both of which are rotatably arranged on the inner wall of the transmission chamber 11, the linkage rod 531 is provided with a first incomplete gear 532 and a second incomplete gear 533, and the transmission rod 534 is provided with a first spur gear 535 intermittently meshing with the second incomplete gear 533; the second spur gear 536 and the third spur gear 537 are both arranged on the screw rod 51, the second spur gear 536 is intermittently meshing with the first incomplete gear 532, and the third spur gear 537 is meshing with the first spur gear 535; the driving component 538 is arranged in the oil inlet pipe 7, and is used to drive the linkage rod 531 to rotate.

[0053] After the oil drives the blade 8 to rotate, it will rotate through the linkage rod 531, and the linkage rod 531 will drive the first incomplete gear 532 and the second incomplete gear 533 to rotate. The tooth segments of the first incomplete gear 532 and the second incomplete gear 533 are in opposite directions.

[0054] Assuming that the linkage rod 531 rotates counterclockwise, it will drive the first incomplete gear 532 and the second incomplete gear 533 to rotate counterclockwise. When the first incomplete gear 532 is meshed with the second spur gear 536, it will drive the screw rod 51 to rotate clockwise, while the second incomplete gear 533 is not meshed with the first spur gear 535, and the screw rod 51 rotates clockwise; and when the linkage rod 531 rotates to the point where the second incomplete gear 533 is meshed with the first spur gear 535, the first incomplete gear 532 is not meshed with the second spur gear 536, and the first spur gear 535 will rotate clockwise, and the first spur gear 535 will drive the third spur gear 537 and the screw rod 51 to rotate counterclockwise. In summary, the screw rod 51 rotates back and forth, so the screw rod 51 will drive the nut seat 52 and the scraper ring 10 to move up and down.

[0055] In this embodiment, preferably, please refer to Figure 5-6 The driving assembly 538 includes: a support rod 5381, which is arranged on the inner wall of the oil inlet pipe 7, and a rotating shaft 5382 is rotatably arranged on the support rod 5381, one end of the rotating shaft 5382 is connected to the blade 8, and the other end is provided with a first bevel gear 5383; a second bevel gear 5384 is arranged on the upper end of the linkage rod 531 and meshes with the first bevel gear 5383. When the oil drives the blade 8 to rotate, it drives the rotating shaft 5382 to rotate, and the rotating shaft 5382 drives the first bevel gear 5383 to rotate, and the first bevel gear 5383 drives the second bevel gear 5384 and the linkage rod 531 to rotate.

[0056] In this embodiment, preferably, please refer to Figure 3-5 and Figure 8 A collecting chamber 12 is also provided in the filter box 3, a through port 13 communicating with the collecting chamber 12 is provided at the bottom of the oil chamber 6, a cleaning pipe 14 and an oil extraction pipe 15 communicating with the collecting chamber 12 are provided on the filter box 3, the oil extraction pipe 15 is connected to the auxiliary oil pump in the oil tank 2, and the oil outlet of the auxiliary oil pump passes the oil into the oil tank 2; a filter plate 27 is also provided in the collecting chamber 12, a baffle 16 adapted to the through port 13 is movably provided on the collecting chamber 12, and a pushing component 17 for driving the baffle 16 to move is provided in the collecting chamber 12.

[0057] When the impurities in the oil chamber 6 are to be processed, the filter box 3 can be stopped, that is, the main oil pump and the connecting pipe 4 can be stopped from sucking oil, and then the baffle 16 can be moved by the pushing component 17 to Figure 5 and Figure 8For example, at this time, the baffle 16 moves to the right, so that the baffle 16 no longer blocks the passage 13, and then the auxiliary oil pump is started, and the auxiliary oil pump will suck oil through the oil extraction pipe 15, and the oil in the oil chamber 6 will enter the collection chamber 12 through the passage 13, and then be drawn away through the oil extraction pipe 15, and then discharged into the oil tank 2 through the oil outlet after passing through the auxiliary oil pump, completing the circuit. In this process, the oil in the oil chamber 6 will enter the collection chamber 12 with impurities, and will be blocked by the filter plate 27, that is, the impurities will be concentrated on the filter plate 27. After operating for a period of time, the baffle 16 is driven to move back by the pushing component 17, so that the baffle 16 blocks the passage 13 again. At this time, the oil in the oil passage chamber 6 cannot enter the collecting chamber 12. After that, the auxiliary oil pump draws out the residual oil in the collecting chamber 12 through the oil suction pipe 15, and then the impurities on the filter plate 27 can be cleaned and removed through the cleaning pipe 14. The impurities can be easily cleaned without disassembling the oil tank 2 and the filter box 3, which saves complicated work process, time and effort; it also prevents impurities from being in the oil passage chamber 6 for a long time to cause blockage and other effects on the filter cartridge 9, better protects the filter cartridge 9, and improves its subsequent filtering effect, which is highly practical.

[0058] In this embodiment, preferably, please refer to Figure 1 and Figure 5 The outer end of the cleaning pipe 14 penetrates the outer wall of the oil tank 2, and the inner thread of the cleaning pipe 14 is connected with a sealing plug 21. The outer end of the cleaning pipe 14 can be sealed by the sealing plug 21 to ensure the sealing performance. When the sealing plug 21 is removed, the impurities on the filter plate 27 can be cleaned through the cleaning pipe 14.

[0059] In this embodiment, preferably, please refer to Figure 5 and Figure 8 The pushing component 17 includes: a telescopic member 171, which is arranged in the collection chamber 12, and a push plate 172 is arranged at the telescopic end of the telescopic member 171; a connecting plate 173, which is slidably arranged on the upper wall of the collection chamber 12 and is respectively connected to the baffle 16 and the push plate 172. The telescopic member 171 in the present application can adopt an electric telescopic rod. After the telescopic member 171 is started, the extension or shortening of the telescopic end of the telescopic member 171 will drive the push plate 172 to move, and the movement of the push plate 172 will drive the connecting plate 173 and the baffle 16 to move. At the same time, the movement of the push plate 172 will push the impurities on the filter plate 27, so that the impurities on the inner side of the filter plate 27 move outward, so that it is more convenient to clean the impurities on the filter plate 27 in the future, and the operation is simple and convenient, and the practicability is strong.

When the connecting plate 173 and the baffle 16 move, the connecting plate 173 drives the slide block 20 to slide along the slide rod 19, thereby improving the smoothness and stability of the movement of the baffle 16.

[0061] In this embodiment, preferably, please refer to Figure 2 and Figure 7 The bottom of the oil passage chamber 6 is provided with a pedestal 22, and the filter cartridge 9 is detachably arranged on the pedestal 22. The outer wall of the pedestal 22 is slidably provided with a collar 23, and the collar 23 is provided with a plurality of scrapers 24. The filter cartridge 9 can be detached for cleaning or replacement; the pedestal 22 and the bottom of the oil passage chamber 6 form an annular groove, which is convenient for the storage of impurities in the oil passage chamber 6. When the auxiliary oil pump sucks oil through the oil extraction pipe 15, the oil in the oil passage chamber 6 enters the collecting chamber 12 through the through port 13, and the oil will impact the plurality of scrapers 24, thereby driving the scrapers 24 and the collar 23 to rotate, and the scrapers 24 will scrape and push the impurities on the annular groove at the bottom of the oil passage chamber 6, and finally push the impurities to the position of the through port 13, thereby improving the cleaning effect of the impurities in the oil passage chamber 6, and the practicability is strong.
