[0030] Reference Figure 1 , which is the first embodiment of the utility model, and this embodiment provides a filtering structure, which includes a filtering unit 100, and the filtering unit 100 includes a placement tube 101, a filtering component 102 arranged inside the placement tube 101, and a power component 103 installed on the inner circle of the filtering component 102.

[0031] When in use, the setting of the placement tube 101 can realize independent installation of the filter component 102 and the power component 103, without cutting and installing the pipeline, which is convenient for assembly and production. The placement tube 101 can be connected to the water transport pipeline through a flange, and the filter component 102 can filter the dirt in the water flowing through the placement tube 101. Through the action of the power component 103, when the water flows through, it drives the power component 103 to run and scrape the filter component 102 to prevent the dirt from clogging the filter component 102.

[0032] Example 2

[0033] Reference Figure 2 to Figure 5 , which is the second embodiment of the utility model, and is different from the first embodiment in that: a first groove 101a is provided on the outer side of the placement tube 101, and a cover plate 101b is hingedly connected to the placement tube 101 at the position of the first groove 101a through a hinge, and the cover plate 101b is adapted to the first groove 101a, and the outer ring of the placement tube 101 and the outer ring of the cover plate 101b are fixedly connected to a fixing plate 101c, and a positioning hole 101d is provided on the fixing plate 101c, and a connecting pipe 101i is fixedly connected to one side of the placement tube 101, and a sewage pipe 101j is fixedly connected to one side of the connecting pipe 101i.

[0035] By setting the fixing plate 101c and the positioning hole 101d, the cover plate 101b and the first groove 101a can be firmly connected together, and by the combination of the fixing strip 101e and the second groove 101f, as well as the sealing gasket set between the first groove 101a and the cover plate 101b, the sealing of the connection between the two is ensured, and by setting the rail 101g and the through hole 101h, the filter assembly 102 can be snapped in and fixed, thereby ensuring the stability of the filter assembly 102 when in use.

[0036] Through the setting of the connecting pipe 101i and the drain pipe 101j, before starting the water lubrication, first open the valve on the drain pipe 101j, and discharge the smaller impurities on the filter component 102 through the cooperation with the power component 103. When the water discharged from the drain pipe 101j is clean, close the valve on the drain pipe 101j, open the valve 202, and transport the water to the universal nozzle 203 to achieve lubrication of the arc gate water seal.

[0037] Specifically, the filter assembly 102 includes a connecting ring 102a, a filter cover 102b fixed to one side of the connecting ring 102a, a connecting rod 102c fixed to the other side of the connecting ring 102a, and a scraper 102i installed on the inner circle of the filter cover 102b. The connecting ring 102a is adapted to the rail 101g, and the connecting rod 102c is adapted to the through hole 101h.

[0038] Furthermore, one end of the connecting rod 102c is fixedly connected to a fixing ring 102d, and the inner ring of the fixing ring 102d is symmetrically provided with two slots 102e, and the inner ring of the fixing ring 102d on a side away from the connecting ring 102a is chamfered.

[0039] By setting the connecting ring 102a, it is ensured that it can cooperate with the rail 101g, and the stable installation of the filter component 102 is guaranteed. The filter cover 102b can filter the passing water flow. The fixing ring 102d connected by the connecting rod 102c can realize the installation of the power component 103 and ensure the stability of the power component 103. The number of connecting rods 102c can be adjusted according to actual conditions, but the stability of the connection between the fixing ring 102d and the connecting ring 102a must be guaranteed.

[0040] The side of the fixing ring 102d away from the connecting ring 102a is chamfered so that one side thereof can be in close contact with the inner wall of the placement tube 101. In addition, the chamfered setting can also prevent dirt from adhering to one side of the fixing ring 102d.

[0041] Specifically, the inner ring of the connecting ring 102a is fixedly connected with a transverse plate 102f, and the bottom inner center of the filter cover 102b is rotatably connected with a rotating rod 102g, and one end of the rotating rod 102g close to the connecting ring 102a passes through the transverse plate 102f, and the transverse plate 102f and the rotating rod 102g are rotatably matched; the two ends of the scraper 102i are fixed to the outer ring of the rotating rod 102g, the scraper 102i is adapted to the inner ring of the filter cover 102b, and one end of the rotating rod 102g close to the connecting ring 102a is fixedly connected to the limiting column 102h.

[0042] The installation of the rotating rod 102g can be stabilized by the horizontal plate 102f, and the rotation cooperation with the rotating rod 102g through the bearing ensures the stable rotation of the rotating rod 102g. The scraper 102i can be set to clean the inner wall of the filter cover 102b to prevent dirt from clogging the filter cover 102b. The limiting column 102h can cooperate with the power component 103, and the operation of the power component 103 can drive the rotation of the rotating rod 102g.

[0043] Specifically, the power assembly 103 includes a rotating shaft 103a, a fan blade 103b fixed to the outer ring of the rotating shaft 103a, a limiting groove 103c opened at one end of the rotating shaft 103a close to the filter cover 102b, and an adjusting member 103d arranged at the end of the rotating shaft 103a away from the filter cover 102b, the limiting groove 103c is engaged with the limiting column 102h, and the rotating shaft 103a is arranged on the center line connecting the connecting ring 102a and the fixing ring 102d.

[0044] By setting the rotating shaft 103a and the fan blade 103b, when water flows in the placement tube 101, it can drive the rotating shaft 103a to rotate, and through the engagement of the limiting groove 103c and the limiting column 102h, drive the rotating rod 102g to rotate, and at the same time, one end of the rotating shaft 103a can be placed in the same straight line as the rotating rod 102g, and one end of the rotating shaft 103a can be supported. Through the cooperation of the adjusting member 103d and the card slot 102e, the other end of the rotating shaft 103a can be supported, thereby ensuring the stable operation of the power component 103, and also making it convenient for the staff to disassemble, repair and replace the power component 103.

[0045] Specifically, the adjusting member 103d includes a mounting plate 103d-1, a fixing sleeve 103d-2 fixed to one side of the mounting plate 103d-1, a third groove 103d-3, two fourth grooves 103d-4 and two fifth grooves 103d-5 opened in the mounting plate 103d-1, and a spring 103d-8 and a block 103d-7 arranged in the fourth groove 103d-4. The fixing sleeve 103d-2 is rotatably connected to one end of the rotating shaft 103a through a bearing.

[0046] Furthermore, the third groove 103d-3 is located at the center of the mounting plate 103d-1, and the two fourth grooves 103d-4 are symmetrically arranged at the two ends of the mounting plate 103d-1. The third groove 103d-3 is connected to the fourth groove 103d-4 through the fifth groove 103d-5; an adjusting rod 103d-6 is rotatably connected in the third groove 103d-3, and the two ends of the adjusting member 103d are respectively fixed to one end of the fourth groove 103d-4 and one end of the block 103d-7, and the adjusting rod 103d-6 is connected by a connecting rope 103d-9, and the connecting rope 103d-9 slides in the fifth groove 103d-5, and the block 103d-7 is engaged with the slot 102e.

[0047] By setting the block 103d-7, a stable connection between the adjusting member 103d and the fixing ring 102d can be achieved. By connecting the block 103d-7 and the adjusting rod 103d-6 through the connecting rope 103d-9, the block 103d-7 can be driven to move toward the fourth groove 103d-4 when the adjusting rod 103d-6 is rotated. By the action of the spring 103d-8, the block 103d-7 can be always kept in an extended state to ensure the stable engagement between the block 103d-7 and the slot 102e. In addition, by having inclined surfaces on both the fixing ring 102d and the block 103d-7, convenience during installation can be ensured.

[0048] When in use, when it is necessary to disassemble and clean the filter assembly 102 and the power assembly 103, first close the water inlet of the section of the pipeline and release the fixation of the cover plate 101b and the first groove 101a, then open the cover plate 101b, and then take out the filter assembly 102 and the power assembly 103 from the placement tube 101. After taking them out, you can first clean the inside of the placement tube 101. After cleaning, turn the adjustment rod 103d-6 counterclockwise. The adjustment rod 103d-6 is rotated When the block 103d-7 is driven to move to the fourth groove 103d-4 by the connecting rope 103d-9, when the block 103d-7 is disengaged from the slot 102e, the power assembly 103 can be taken out from the filter assembly 102. After taking it out, the adjusting rod 103d-6 is loosened, and the block 103d-7 can be driven to return to its original position by the action of the spring 103d-8. Due to the length of the connecting rope 103d-9, the block 103d-7 can be prevented from being removed from the fourth groove 103d-4. The filter assembly 102 and the power assembly 103 can be cleaned separately after the power assembly 103 is taken out. The cooperation between the adjusting member 103d and the filter assembly 102 also facilitates the replacement and repair of the filter assembly 102 or the power assembly 103, which can save costs. When installing, it is necessary to align the position of the block 103d-7 with the slot 102e, and then push the power assembly 103. The limiting column 102h needs to be inserted into the limiting groove 103c to ensure support for one end of the rotating shaft 103a. When the block 103d-7 contacts the fixing ring 102d, it will drive the block 103d-7 to move toward the fourth groove 103d-4. When the block 103d-7 moves to align with the groove 102e, the spring 103d-8 can drive the block 103d-7 to return to its original position, thereby fixing the power component 103 and the filter component 102.
