[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] like Figure 1 As shown, one embodiment of this utility model provides a rainwater and sewage pipe network filtration structure, including a fixed plate 2, an inlet pipe 1 above the fixed plate 2, a top plate 8 movably installed above the inner side of the inlet pipe 1 via a detachable mechanism 7, an outlet pipe 6 below the fixed plate 2, a horizontal groove 5 on one side of the outer surface of the fixed plate 2, a sealing plate 4 movably installed inside the horizontal groove 5 via a sliding disassembly mechanism 3, a U-shaped plate 10 fixedly installed on the outer surface of the sealing plate 4, a first filter plate 9 movably installed above the inner side of the U-shaped plate 10, vertical grooves 17 on both sides below the inner wall of the U-shaped plate 10, connecting blocks 16 movably connected inside the vertical grooves 17 via a rotating disassembly mechanism 15, and a second filter plate 14 fixedly connected to the opposite side of the outer surface of the two connecting blocks 16.

[0024] like Figure 2 As shown, a filter groove 18 is provided on the upper surface of the top plate 8. The inlet pipe 1 and the outlet pipe 6 pass through the interior of the fixed plate 2. Both the inlet pipe 1 and the outlet pipe 6 extend to the inner side of the transverse groove 5. Rubber sealing rings are installed on the inner walls of the inlet pipe 1 and the outlet pipe 6. The ends of the rubber sealing rings extend into the interior of the U-shaped plate 10. The aperture of the filter holes on the outer surface of the first filter plate 9 is larger than the aperture of the filter holes on the outer surface of the second filter plate 14, which improves the sealing performance at the connection between the inlet pipe 1 and the outlet pipe 6 and the U-shaped plate 10. The filter groove 18 can filter larger impurities and improve the filtration effect.

[0025] like Figure 3As shown, the detachable mechanism 7 includes a second fixing plate 704 and a plug rod 702. The plug rod 702 is installed on both sides of the outer surface of the water inlet pipe 1 through the through hole 703. A third spring 701 is sleeved on the outer surface of the plug rod 702. Insertion holes 706 are provided on both sides of the outer surface of the top plate 8. The plug rod 702 can be inserted into the inner side of the insertion hole 706. The second fixing plate 704 is fixedly connected to the inner wall of the water inlet pipe 1. A fourth spring 705 is installed on the upper end surface of the second fixing plate 704. By pulling the plug rod 702, the other end of the plug rod 702 leaves the inner side of the insertion hole 706, releasing the restriction on the top plate 8. The top plate 8 can be pushed upward under the action of the fourth spring 705.

[0026] like Figure 4 As shown, the sliding disassembly mechanism 3 includes strip plates 303, which are installed around the transverse groove 5 via strip grooves 301. The strip plates 303 and the inner wall of the strip grooves 301 are movably connected by a first spring 302. A locking block 304 is installed on the opposite side of the outer surface of every two strip plates 303. The upper and lower ends of the sealing plate 4 are symmetrically provided with locking grooves 305. The transverse groove 5 and the strip grooves 301 are connected by a through groove, and the locking block 304 passes through the through groove. The locking block 304 can... The inner side of the slot 305 is inserted into the slot. A plurality of second springs 306 are installed on one side of the inner wall of the transverse groove 5 through a circular groove. The other end of the second spring 306 is attached to the outer surface of the molded plate 10. By pulling the strip plate 303, it can move inside the strip groove 301, thereby moving the locking block 304. The locking block 304 leaves the inner side of the slot 305, releasing the restriction on the sealing plate 4. The molded plate 10 can be pushed to the outside of the transverse groove 5 under the action of the second spring 306.

[0027] The inner walls of the U-shaped plate 10 are provided with grooves 12 at the front and rear. The inner side of the grooves 12 is movably connected to the sliders 11 by the fifth spring 13. The outer surfaces of the four sliders 11 are fixedly connected to the outer surface of the first filter plate 9. The first filter plate 9 can move up and down inside the U-shaped plate 10 and then return to its original position under the action of the fifth spring 13. This causes some impurities and silt on the surface of the first filter plate 9 to vibrate, which can clean the first filter plate 9 and improve its filtration effect.

[0028] like Figure 5 As shown, the rotating disassembly mechanism 15 includes a turntable 1501, which is installed in front of one side of the vertical groove 17 via a groove 1503. A connecting groove 1504 is provided above the groove 1503, and a vertical shaft 1505 is provided inside the connecting groove 1504. A gear 1507 is sleeved above the vertical shaft 1505, and a rack 1508 is installed above the gear 1507 via a movable cavity 1506. The rack 1508 meshes with the gear 1507, and the rotation of the gear 1507 can drive the rack 1508 to move.

[0029] A limit block 1509 is installed at one end of the rack 1508. A limit groove 1510 is provided on the opposite side of the outer surface of the two connecting blocks 16. The limit block 1509 can be inserted into the inner side of the limit groove 1510. The upper end face of the vertical shaft 1505 is rotatably connected to the inner wall of the movable cavity 1506 through a bearing. A strip block is installed on the rear end face of the rack 1508. A strip groove is provided on the inner wall of the movable cavity 1506, and the strip block is inserted into the inner side of the strip groove. A handle 1502 is installed on the lower end face of the turntable 1501. The movement of the rack 1508 can drive the limit block 1509 to move, thereby improving the stability of the movement of the rack 1508 and the stability of the rotation of the vertical shaft 1505.

[0030] Working principle: When in use, this rainwater and sewage pipe network filtration structure, with its top plate 8 and filter tank 18, can filter larger impurities. The presence of a first filter plate 9 and a second filter plate 14, with the pore size of the first filter plate 9 being larger than that of the second filter plate 14, improves the filtration effect. Furthermore, the inclusion of a slider 11, a sliding groove 12, and a fifth spring 13 allows the first filter plate 9 to move downwards within the U-shaped plate 10 under the impact of rainwater, and then return to its original position under the action of the fifth spring 13. This vibration cleans the first filter plate 9, removing impurities and silt, thus improving its filtration efficiency.

[0031] The top plate can be disassembled by the detachable mechanism. The sliding disassembly mechanism allows the strip plate 303 to move inside the strip groove 301 by pulling it, which in turn moves the locking block 304. The locking block 304 leaves the inside of the slot 305, releasing the restriction on the sealing plate 4. The return plate 10 can be pushed to the outside of the transverse groove 5 under the action of the second spring 306, so that the sealing plate 4 and the return plate 10 can be removed from the inside of the transverse groove 5 to clean the impurities above the first filter plate 9.

[0032] Furthermore, by providing a rotating disassembly mechanism 15, the turntable 1501 can be rotated by the handle. The rotation of the turntable 1501 drives the vertical shaft 1505 to rotate, and the rotation of the gear 1507 drives the rack 1508 to move. The movement of the rack 1508 drives the limiting block 1509 to move. When the limiting block 1509 leaves the inner side of the limiting groove 1510, the second filter plate 14 can be removed from the lower inner side of the U-shaped plate 10. Impurities on the top of the second filter plate 14 can be cleaned. This utility model has a good filtration effect and facilitates the cleaning of the first filter plate 9 and the second filter plate 14, thereby ensuring the subsequent filtration effect.
