[0053] like Figure 1 , Figure 2 and Figure 4As shown, the transmission assembly 7 includes: a motor 701, which is fixed to the first pipe 1. A control terminal not shown in the figure is arranged outside the first pipe 1. The motor 701 is electrically connected to the control terminal. The second pipe 2 is rotatably connected to a reciprocating telescopic rod 703. The telescopic portion of the reciprocating telescopic rod 703 is provided with an inclined annular closed groove. A limit pin sliding in the annular closed groove is arranged in the fixed portion of the reciprocating telescopic rod 703. When the fixed portion of the reciprocating telescopic rod 703 rotates, the limit pin rotates in the annular closed groove, so that the telescopic portion of the reciprocating telescopic rod 703 moves back and forth up and down. The motor The output shaft of 701 and the reciprocating telescopic rod 703 are transmitted through a transmission member 702, and the transmission member 702 is composed of a pulley belt and a bevel gear set, one of which is rotatably connected to the first pipe 1 through a gear shaft, and the other bevel gear is fixedly connected to the fixed part of the reciprocating telescopic rod 703. The transmission member 702 transmits the rotation of the output shaft of the motor 701 to the fixed part of the reciprocating telescopic rod 703, and the telescopic part of the reciprocating telescopic rod 703 is fixedly connected to the sliding ring 4 through a connecting frame, and the second pipe 2 and the filter element housing 3 are both sealed and slidably connected to the connecting frame of the telescopic part on the reciprocating telescopic rod 703.

[0054] The specific working principle is as follows:

[0055] When the operator needs to use the device to repair the hydraulic oil, the hydraulic oil enters the filter element housing 3 through the first pipe 1, the filter element housing 3 blocks the impurities in the hydraulic oil, and then the hydraulic oil is filtered by the filter element housing 3 and discharged into the second pipe 2. The filtered hydraulic oil is discharged through the branch channel 201, and the operator can collect and recycle the discharged hydraulic oil through the collection pipe.

[0056] During the repair of the hydraulic oil, if there are too many impurities in the filter housing 3 causing it to be blocked and the filter housing 3 needs to be automatically cleaned, the operator starts the motor 701 through the control terminal, and the output shaft of the motor 701 transmits the reciprocating telescopic rod 703 through the transmission member 702. The telescopic part of the reciprocating telescopic rod 703 drives the sliding ring 4 to move up and down through its connecting frame. When the sliding ring 4 moves downward, the sliding ring 4 drives the second magnet 501 to move downward through the magnetic force of the first magnet 401, and the second magnet 501 drives the first sliding frame 502 to move downward through the sliding block 5. The first sliding frame 502 moves upward relative to the sliding block 5 under the influence of the hydraulic oil resistance in the filter housing 3, the first elastic member of the first sliding frame 502 is compressed, and the first hole of the sliding block 5 is opened. The sliding ring 4 squeezes the hydraulic oil between the second pipe 2 and the filter housing 3. Oil, so that the hydraulic oil in the second pipeline 2 flows back into the filter element housing 3, the hydraulic oil flowing back into the filter element housing 3 flows upward through the first hole of the sliding block 5, and the returning hydraulic oil backwashes the filter holes on the filter element housing 3 to reduce the amount of impurities blocking the filter holes on the filter element housing 3, prolong the service life of the filter element housing 3, thereby reducing the frequency of disassembly and cleaning of the device, and improving the convenience of using the device. When the sliding ring 4 moves upward, the sliding ring 4 drives the first sliding frame 502 to move upward through the first magnet 401, the second magnet 501 and the sliding block 5, and the first elastic member of the first sliding frame 502 drives it to reset, and the first sliding frame 502 blocks the first hole of the sliding block 5, and the sliding block 5 and the first sliding frame 502 squeeze the hydraulic oil in the filter element housing 3, so that the hydraulic oil in the filter element housing 3 is pressurized and flows into the second pipeline 2.

[0057] When the sliding block 5 moves upward, the sliding block 5 scrapes off the impurities in the filter element housing 3, so that the impurities are gathered on the upper side of the sliding block 5 and the sliding frame 502. When the sliding block 5 moves to contact the squeezing rod 6, the squeezing rod 6 is squeezed by the sliding block 5 and moves upward. The second elastic part of the squeezing rod 6 is stretched. By gathering the impurities on the upper side of the sliding block 5 and the sliding frame 502, the amount of impurities attached to the filter element housing 3 is reduced, thereby extending the service life of the filter element housing 3, thereby reducing the frequency of disassembly and cleaning of the device, and improving the convenience of using the device.

[0058] When the device is no longer in use, the operator turns off the motor 701 through the control terminal and then cleans the device for the next use.

[0059] In order to clean the impurities accumulated on the sliding block 5, as shown in FIG. Figure 2 , Figure 5 and Figure 7As shown, the present invention also includes: a seal 8, which is fixedly connected to the extrusion rod 6, and is used to seal the sliding block 5. The seal 8 is made of a flexible material. When the sliding block 5 moves to contact the extrusion rod 6, the seal 8 seals the upper side of the sliding block 5 to prevent impurities from flowing through the upper side of the sliding block 5; a reflux pipe 9, which is fixedly connected to the second pipe 2, and is used to connect the second pipe 2 with the branch channel 201.

[0060] like Figure 3 and Figure 7 As shown, it also includes: a guide plate 10, which is fixedly connected to the upper side of the filter element housing 3, the guide plate 10 is fixedly connected to the second pipe 2, the guide plate 10 is provided with a guide hole, a filter plate 1001 is installed in the guide hole of the guide plate 10, the filter element housing 3 is provided with a plurality of filter holes 1002, the filter hole 1002 is located on the right side of the guide plate 10, the filter plate 1001 is located on the left side of the sliding block 5, the right end of the return pipe 9 is located on the left side of the guide plate 10, and the left and right sides of the sliding block 5 are provided with flow holes 1003. After the sliding ring 4 moves upward to the extreme position, the sliding ring 4 blocks the filter hole 1002.

[0061] The specific working principle is as follows:

[0062] When the sliding block 5 moves to contact the extrusion rod 6, the extrusion rod 6 moves upward due to the extrusion of the sliding block 5, and the second elastic member of the extrusion rod 6 is stretched, so that the flow hole 1003 moves to the chamber between the filter element housing 3 and the second pipe 2. At this time, the sliding ring 4 blocks the filter hole 1002. When the sliding ring 4 moves downward, the sliding ring 4 extracts the hydraulic oil between the filter element housing 3 and the second pipe 2 through the filter hole 1002, so that the hydraulic oil in the branch channel 201 flows to the filter hole 1002 through the reflux pipe 9, the filter plate 1001 and the two flow holes 1003. When the hydraulic oil passes through the two flow holes 1003, the impurities in the sliding block 5 are flushed to the filter hole 1002, so that the impurities are gathered in the chamber between the filter element housing 3 and the second pipe 2, so that the operator can clean the accumulated impurities without disassembling the device, so as to prevent the device from failing in sealing due to frequent disassembly and assembly, thereby affecting the normal use of the filter element housing 3.

[0063] In order to reduce the probability of impurities blocking the filter hole 1002, as Figure 3 and Figure 7 As shown, the present invention also includes: a fixed block 11, fixedly connected to the second pipe 2, located in the branch channel 201, the left end of the return pipe 9 is located on the left side of the fixed block 11, and the fixed block 11 is provided with a second hole; a second sliding frame 1101, slidably connected to the fixed block 11, and a third elastic member is fixed between the second sliding frame 1101 and the fixed block 11, wherein the third elastic member of the second sliding frame 1101 is a compression spring, and the second sliding frame 1101 is used to block the second hole of the fixed block 11.

[0064] The specific working principle is as follows:

[0065] During the downward movement of the sliding ring 4, the second sliding frame 1101 is subjected to less pressure from the hydraulic oil, and the hydraulic oil in the second pipeline 2 flows to the left through the second hole of the fixed block 11. When the sliding ring 4 moves upward, the pressure from the hydraulic oil on the second sliding frame 1101 increases, causing the second sliding frame 1101 to move to the left. The third elastic member of the second sliding frame 1101 is gradually compressed, and the second sliding frame 1101 blocks the second hole of the fixed block 11. The hydraulic oil in the second pipeline 2 flows from bottom to top through the filter hole 1002, and backwashes the filter hole 1002 to reduce the probability of impurities clogging the filter hole 1002.

[0066] In order to reduce the amount of impurities entering the filter housing 3, Figure 1 , Figure 2 and Figure 7 As shown, it also includes: a partition plate 12, which is fixed to the first pipe 1, and magnetic sources 1201 are arranged on the upper and lower sides of the first pipe 1. The two magnetic sources 1201 are respectively located on both sides of the partition plate 12, the upper magnetic source 1201 is a positive pole, and the lower magnetic source 1201 is a negative pole. The sliding ring 4 and the sliding block 5 are both magnetic shielding materials, which are used to isolate the first magnet 401, the second magnet 501 and the magnetism of impurities in the hydraulic oil. The magnetic source 1201 is used to make the impurities in the hydraulic oil generate magnetism. When the impurities in the hydraulic oil flow through the magnetic source 1201, the magnetic source 1201 is an electric field that loads positive or negative charges on impurities in the hydraulic oil; the rotating frame 13 is rotatably connected to the first pipeline 1, the rotating frame 13 is fixedly connected to the output shaft of the motor 701, and the rotating frame 13 is fixedly connected to a plurality of flexible filter screens 1301. After the hydraulic oil flows through the magnetic source 1201, impurities carrying positive and negative charges are adsorbed on each other, causing the impurities to aggregate, so as to reduce the amount of small particle impurities in the hydraulic oil in the filter element housing 3, thereby preventing excessive small particle impurities from being difficult to intercept, resulting in the filter element housing 3 affecting the repair effect of the hydraulic oil.

[0067] The specific working principle is as follows:

[0068] During the repair of the hydraulic oil, the output shaft of the motor 701 drives several flexible filter screens 1301 to rotate through the rotating frame 13. The flexible filter screens 1301 mix impurities carrying positive and negative charges. While the impurities are gathering, the flexible filter screens 1301 collect the impurities in the form of a net bag to reduce the amount of impurities entering the filter element housing 3, perform preliminary separation of the impurities, reduce the clogging probability and cleaning frequency of the filter element housing 3, thereby extending the service life of the filter element housing 3 and improving the convenience of using the device.

[0069] In order to collect the impurities scraped off the filter housing 3, Figure 1 , Figure 2 and Figure 8 As shown, the present invention also includes: a liquid capsule 14, which is fixedly connected to and connected to the second pipe 2, and the connection point between the liquid capsule 14 and the second pipe 2 is located below the sliding ring 4. A flexible ring 1401 is fixedly connected in the liquid capsule 14. The principle of the flexible ring 1401 is similar to that of a valve structure. When the upper side of the flexible ring 1401 is not affected by liquid pressure, the hole in the middle of the flexible ring 1401 is closed. After the flexible ring 1401 is subjected to liquid pressure, the hydraulic oil squeezes the flexible ring 1401 downward, so that the flexible ring 1401 opens downward to form a hole; a collecting shell 15, which is fixedly connected to the first pipe 1 and connected to the liquid capsule 14. The collecting shell 15 is located on the lower side of the first pipe 1 and is used to collect impurities in the hydraulic oil, so that the impurities are accumulated in the collecting shell 15 below the first pipe 1, thereby facilitating the operator to collect the impurities.

[0070] The specific working principle is as follows:

[0071] During the upward movement of the sliding ring 4, the hole of the flexible ring 1401 is closed. When the sliding ring 4 moves downward, part of the hydraulic oil is squeezed into the liquid capsule 14 by the sliding ring 4. The liquid capsule 14 expands due to the hydraulic pressure, causing the hole of the flexible ring 1401 to open downward. The sliding ring 4 scrapes off the impurities attached to the outside of the filter element housing 3. The impurities follow the hydraulic oil into the liquid capsule 14 and flow downward through the flexible ring 1401. When the sliding ring 4 moves upward, the liquid capsule 14 contracts and resets, squeezing the hydraulic oil inside it to flow back. At this time, the holes of the flexible ring 1401 no longer flow impurities, so that most of the impurities are blocked on the lower side of the liquid capsule 14. Finally, the impurities are gradually deposited in the collection shell 15, so that the impurities can be centrally cleaned, thereby reducing the frequency of disassembly and cleaning of the device, thereby improving the convenience of using the device.

[0072] like Figure 1-Figure 8 As shown, a hydraulic oil repair method is based on the above-mentioned hydraulic oil repair system, and the specific steps are as follows:

[0073] Step 1: The hydraulic oil enters the first pipeline 1, the magnetic source 1201 applies positive and negative charges to the impurities in the hydraulic oil, the motor 701 is turned on and drives the rotating frame 13 to rotate through its output shaft, the rotating frame 13 drives a plurality of flexible filter screens 1301 to collect the impurities, and then the hydraulic oil enters the filter element housing 3, and the filter element housing 3 filters the impurities in the hydraulic oil;

[0074] Step 2: During the rotation of the output shaft of the motor 701, the output shaft of the motor 701 transmits the reciprocating telescopic rod 703 through the transmission member 702, and the telescopic portion of the reciprocating telescopic rod 703 drives the sliding ring 4 to move up and down through the connecting frame;

[0075] Step 3: When the sliding ring 4 moves downward, the sliding ring 4 drives the first sliding frame 502 to move downward through the first magnet 401, the second magnet 501 and the sliding block 5, the first hole of the sliding block 5 opens, the hydraulic oil in the second pipeline 2 flows back into the filter element housing 3 and flows upward through the first hole of the sliding block 5, and the refluxed hydraulic oil backwashes and cleans the filter holes on the filter element housing 3;

[0076] Step 4: When the sliding block 5 starts to move downward, the impurities on the sliding block 5 are located in the chamber between the second pipe 2 and the filter element housing 3, and the sliding ring 4 squeezes the hydraulic oil, and the hydraulic oil flushes the upper side of the sliding block 5 through the return pipe 9, the filter plate 1001 and the flow hole 1003, flushing the impurities in the sliding block 5;

[0077] Step 5: When the sliding ring 4 moves downward, the hole of the flexible ring 1401 opens, and the sliding ring 4 scrapes off the impurities attached to the outside of the filter element housing 3. The impurities follow the hydraulic oil into the liquid bag 14 and flow downward through the flexible ring 1401. Finally, the impurities are collected in the collection shell 15.

[0078] Step 6: When the sliding ring 4 moves upward, the first sliding frame 502 blocks the first hole of the sliding block 5, and the sliding block 5 and the first sliding frame 502 squeeze the hydraulic oil in the filter element housing 3, so that the hydraulic oil in the filter element housing 3 is pressurized and flows into the second pipe 2;

[0079] Step 7: When the sliding ring 4 moves upward, the pressure of the hydraulic oil on the second sliding frame 1101 increases, so that the second sliding frame 1101 moves, and the second sliding frame 1101 blocks the second hole of the fixed block 11, and the hydraulic oil in the second pipeline 2 flows through the filter hole 1002 from bottom to top, and backwashes the filter hole 1002;

[0080] Step 8: The hydraulic oil filtered by the filter element housing 3 is discharged from the branch channel 201 through the second pipe 2. The discharged hydraulic oil can be collected and recycled. When the device is stopped, the motor 701 is turned off and the device is cleaned for the next use.
