When the roller 55 leaves the outer surface of the filter body 1, the torsion spring 513 can release the torsional force and thereby drive the roller 55 to rotate in the opposite direction.

[0046] Reference Figure 8 、 Figure 9And the telescopic slide rod 52 is fixed on the outer surface of the moving block 53 on one side of the gear ring 511, and the gear ring 511 is meshed with the vertical gear 510 on one side, and the surface of the vertical gear 510 away from the fixed base 51 is fixedly connected with the second single pulley 58 located on the lower part of the two vertical gears, and the surface of the lower second single pulley 58 away from the vertical gear 510 is rotatably connected with the surface of the moving block 53 on one side of the gear ring 511, and the upper second single pulley 58 is rotatably arranged on the fixed protrusion on the surface of the moving block 53 away from the fixed base 54, and the middle grooves of the two second single pulleys 58 are clamped with the second belt 59, and the two second single pulleys 58 can drive the second belt 59 to move around the second single pulley 58 when rotating, and the upper second single pulley 58 in the two second single pulleys 58 is fixedly connected with the second bevel gear 57 away from the fixed base 51 through the middle fixed shaft, and the second bevel gear 57 is meshed with the first bevel gear 56 away from the second single pulley 58, and the first bevel gear 56 is fixedly connected with the roller 55 away from the second bevel gear 57, and the cleaning brush 6 with good cleaning effect for the filter screen hole is rotatably arranged on the surface of the moving block 53 away from the fixed base 51, and the inner surface of the cleaning brush 6 is fixedly connected with the outer surface of the telescopic slide rod 52 away from the moving block 53.

[0047] When the beam 4 moves, the entire telescopic rotating mechanism 5 moves, and when the entire telescopic rotating mechanism 5 moves, the cleaning brush 6 in it first contacts the outer surface of the filter screen body 1, and as the beam 4 continues to move, the cleaning brush 6 will be pushed backward by the filter screen body 1, and when the cleaning brush 6 moves backward, the telescopic slide rod 52 will be retracted, so that the cleaning brush 6 can retreat to the lower part of the roller 55, and at this time the roller 55 will contact the outer surface of the filter screen body 1, and rotate during continuous movement.

[0048] When the roller 55 rotates on the surface of the filter screen body 1, the torsional spring 513 is rotated and stored, and when the second single pulley 58 rotates, the other side of the first bevel gear 56 is rotated, and the first bevel gear 56 rotates to drive the second bevel gear 57 to rotate, and the second bevel gear 57 rotates to drive the second single pulley 58 on the upper part to rotate, and the second single pulley 58 on the upper part rotates to drive the second belt 59 to move around the two second single pulleys 58, thereby driving the second single pulley 58 on the bottom to rotate.

[0050] It should be noted that the roller 55 on the upper part of the fixed base 54 protrudes from the edge of the moving block 53, and the distance of the roller 55 protruding is greater than the width of the cleaning brush 6, so that the rotation of the roller 55 is not affected after the cleaning brush 6 is retracted, and the retracted end of the telescopic slide rod 52 is fixedly connected with the moving block 53, and the extension end of the telescopic slide rod 52 is fixedly connected with the cleaning brush 6, so that the cleaning brush 6 can be independently adjusted and will not interfere with the connection between the roller 55 and the surface of the filter screen body 1, and the diameter of the cleaning brush 6 is smaller than the diameter of the mesh of the filter screen body 1.

[0052] The implementation principle of the pressure increasing valve ring filter screen structure in the embodiment of the application is that the filter screen body 1 is installed into the pressure increasing valve, then the micro motor 31 is connected with the PLC controller of the pressure increasing valve, and when the filter screen body 1 needs to be cleaned after the pressure increasing valve runs for a period of time, the controller can send instructions to the micro motor 31 to make the micro motor 31 work by being electrified, then the first single pulley 32 is driven to rotate by the rotation of the output end of the micro motor 31, and then the first belt 33 is moved, and the first belt 33 drives the fixed block 38 and the horizontal rod 37 to move, and the horizontal rod 37 can drive the T-shaped slide rod 35 to move when moving, and the horizontal rod 37 can move horizontally in the horizontal sliding groove 36 to realize back and forth reciprocating movement, so that the T-shaped slide rod 35 can drive the horizontal beam 4 to realize back and forth reciprocating movement.

[0053] When the crossbeam 4 moves, the whole telescopic rotating mechanism 5 will move, and the cleaning brush 6 in the telescopic rotating mechanism 5 will contact the outer surface of the filter screen body 1 during the movement, and the cleaning brush 6 will be pushed backward by the filter screen body 1 with the continuous movement of the crossbeam 4, so as to drive the telescopic slide rod 52 to retract back, so that the cleaning brush 6 retreats to the lower part of the roller 55, and at this time the roller 55 will contact the outer surface of the filter screen body 1 and rotate during the continuous movement, and at the same time drive the torsional spring 513 to rotate and store energy.

[0054] The second single pulley 58 rotates at the same time to drive the first bevel gear 56 on the other side to rotate, and the first bevel gear 56 rotates to drive the second bevel gear 57 to rotate, and the second bevel gear 57 rotates to drive the second single pulley 58 at the upper part to rotate, so as to drive the second belt 59 to move around the two second single pulleys 58, and then drive the second single pulley 58 at the bottom to rotate.
