It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1:

[0020] Please see Figure 1 , Figure 3 as well as Figure 4This invention provides a technical solution: an anti-clogging rainwater and sewage diversion device, comprising a rainwater and sewage diversion cylinder 1, with a sewage conveying pipe 2 and a rainwater pipe connector 3 inserted into the surface of the rainwater and sewage diversion cylinder 1. The rainwater pipe connector 3 is located below the sewage conveying pipe 2. A manhole cover 7 is hinged to the top of the rainwater and sewage diversion cylinder 1, and a retaining ring 8 is provided below the manhole cover 7. The retaining ring 8 is fixed to the inner wall of the rainwater and sewage diversion cylinder 1. A water collection trough 11 is opened on the top surface of the manhole cover 7, and a circular drain outlet 12 and an oblong drain outlet 13 are opened on the bottom surface of the water collection trough 11. A lifting seat 16 is movably inserted inside the water collection trough 11. A reserved opening 17 is opened on the top surface of the lifting seat 16, and a mesh plate 19 is movably inserted inside the reserved opening 17. A metal mesh cover 24 is fixed to the bottom surface of the lifting seat 16, and an electric push rod 31 is fixed to the bottom surface of the top plate of the lifting seat 16. The piston rod of the electric push rod 31 is fixed to the bottom surface of the water collection trough 11, and a photovoltaic panel is embedded in the top surface of the lifting seat 16. Component 33 is used to power the electric push rod 31. By adding a lifting seat 16 to the manhole cover 7, when the lifting seat 16 is inserted into the water collection tank 11, the manhole cover 7 drains water into the rainwater and sewage diversion cylinder 1 through the reserved opening 17 and the drainage round opening 12. When the ground rainwater volume is large, the lifting seat 16 is raised. At this time, the metal mesh cover 24 is exposed. Rainwater can not only be discharged into the rainwater and sewage diversion cylinder 1 through the reserved opening 17 and the drainage round opening 12, but also flow into the water collection tank 11 after passing through the metal mesh cover 24, and fall into the rainwater and sewage diversion cylinder 1 through the elongated oval drainage outlet 13. That is, the drainage round opening 12 and the elongated oval drainage outlet 13 drain water together, which improves the drainage speed of the manhole cover 7 and avoids the water accumulation problem caused by the blockage of the drainage round opening 12. It further solves the problems of slow drainage speed of the rainwater outlet and ground water accumulation caused by the blockage of the rainwater outlet in the existing rainwater and sewage diversion equipment. It can expand the drainage area of ​​the manhole cover, thereby improving the rainwater drainage speed. Example 2:

[0021] See attached document Figure 2 , Figure 5 , Figure 8 as well as Figure 16Based on Embodiment 1, in order to fix the manhole cover 7 covering the top of the rainwater and sewage diversion cylinder 1, a notch 4 is provided on the top surface of the rainwater and sewage diversion cylinder 1. A limiting shaft 6 is fixed between the two parallel sidewalls of the notch 4. The limiting shaft 6 passes through the connecting handle 5. One end of the connecting handle 5 is fixed to the sidewall of the manhole cover 7. Side grooves 9 are provided on both the top and bottom surfaces of the manhole cover 7. The side grooves 9 are annular grooves. The outer diameter of the side grooves 9 is equal to the diameter of the top surface of the manhole cover 7. A rubber ring 10 is fixed inside the side grooves 9. The outer diameter of the rubber ring 10 is larger than the diameter of the top surface of the manhole cover 7. A collection groove 34 is provided on the top surface of the rainwater and sewage diversion cylinder 1. The collection groove 34 is in the shape of a " An L-shaped groove and a receiving groove 34 are provided with an insert block 35 that is movably inserted inside. The insert block 35 has an L-shaped plate structure. One end of the insert block 35 passes through the receiving groove 34 and is inserted into a slot 36. The slot 36 is located on the side wall of the manhole cover 7. A rubber clamp 37 is fixed between the insert block 35 and the receiving groove 34. The height of the insert block 35 is less than the height of the receiving groove 34. A paddle 38 is fixed on the top surface of the insert block 35. An elastic band 39 is fixed on the outer side of the paddle 38. The edge of the elastic band 39 is fixed to the surface of the receiving groove 34. A second retrieval groove 40 is provided on the top surface of the manhole cover 7. A pull rod 41 is fixed between the two parallel side walls of the second retrieval groove 40.

[0022] After the manhole cover 7 is placed over the opening of the storm drain 1, it overlaps the retaining ring 8 to prevent it from falling. With the rubber clamp 37 in its initial state, one end of the support block 35 is inserted into the slot 36. At this time, the manhole cover 7 is fixed above the retaining ring 8, meaning it will not shake or open. To open the manhole cover 7, push the lever 38 with your finger to cause the support block 35 to press against the rubber clamp 37 until one end of the support block 35 protrudes from the slot 36. At this point, the manhole cover 7 is no longer braked, and the other end... With one hand, the fingers pinch the lever 41 to lift the manhole cover 7. As the manhole cover 7 is lifted, the connecting handle 5 rotates around the limiting shaft 6 and opens. The reason for adding an elastic band 39 between the lever 38 and the storage groove 34 is to prevent debris from the bottom surface from entering the storage groove 34 and blocking the movement of the insert block 35. This further solves the problems of slow drainage speed of rainwater inlet and water accumulation caused by rainwater inlet blockage in existing rainwater and sewage diversion equipment. It can expand the drainage area of ​​the manhole cover, thereby improving the rainwater drainage speed. Example 3:

[0023] See attached document Figure 7 , Figure 15 as well as Figure 17On the basis of the second embodiment, in order to realize that when the lifting seat 16 is inserted into the inside of the water collecting tank 11, rainwater is conveyed into the rainwater and sewage separation cylinder 1 through the circular drainage ports 12, the water collecting tank 11 is a circular tank, a plurality of circular drainage ports 12 are provided, the plurality of circular drainage ports 12 are arranged circumferentially with the circular bottom surface of the water collecting tank 11 as an axis, a plurality of oblong drainage ports 13 are provided, the plurality of oblong drainage ports 13 are radially distributed along the circular bottom surface of the water collecting tank 11, a water delivery pipe 14 is fixed on the bottom surface of the water collecting tank 11, the water delivery pipes 14 correspond to the circular drainage ports 12 one by one, the inner diameter of the water delivery pipe 14 is equal to the caliber of the circular drainage port 12, the top end of the water delivery pipe 14 is sleeved with a casing pipe 15, the casing pipe 15 is fixed on the bottom surface of the top plate of the lifting seat 16, the reserved port 17 is an inverted "convex" shaped circular port, and the bottom caliber of the reserved port 17 is equal to the inner diameter of the casing pipe 15; a connecting ring 18 is sleeved outside the screen plate 19, the connecting ring 18 is a circular plate structure with a "concave" shaped cross section, a rubber connecting ring 20 is sleeved outside the connecting ring 18, the rubber connecting ring 20 is a "convex" shaped annular structure, the outer annular surface of the rubber connecting ring 20 is fixed on the side wall of the top notch of the reserved port 17, a first digging groove 21 is opened on the top surface of the connecting ring 18, and the first digging groove 21 is a "convex" shaped annular groove.

[0024] When the lifting seat 16 is inserted into the water collecting tank 11, the casing pipe 15 is sleeved above the water delivery pipe 14. After falling on the lifting seat 16 and passing through the screen plate 19, rainwater falls along the casing pipe 15 and the water delivery pipe 14 through the circular drainage ports 12 into the rainwater and sewage separation cylinder 1. When the mesh holes of the screen plate 19 are clogged, fingers are digged into the first digging groove 21 to pull the connecting ring 18 upward, the connecting ring 18 stretches the rubber connecting ring 20 to deform. After the connecting ring 18 is released, the rubber connecting ring 20 rebounds and pulls the connecting ring 18 to knock the surface of the reserved port 17. After repeatedly stretching the connecting ring 18 for multiple times and then releasing it, the generated vibration shakes off the blockages in the mesh holes of the screen plate 19; the problem of ground ponding caused by slow drainage speed of the rainwater inlet and blockage of the rainwater inlet existing in the existing rainwater and sewage separation equipment is further solved; the drainage area of the manhole cover can be enlarged, thereby increasing the rainwater drainage speed. Example 4:

[0025] Refer to the attached Figures 12 to 14On the basis of the third embodiment, in order to realize that after the lifting seat 16 is lifted, rainwater passes through the metal mesh cover 24 and then falls into the rainwater-sewage separation cylinder 1 through the circular drainage opening 12 and the oblong drainage opening 13, a plurality of traction rods 22 are fixed on the bottom surface of the lifting seat 16, the bottom ends of the plurality of traction rods 22 are all fixed on the top surface of the backing plate 23, the metal mesh cover 24 is fixed between the top surface of the backing plate 23 and the bottom surface of the lifting seat 16, the outer diameter of the metal mesh cover 24 is equal to the outer diameter of the backing plate 23, an assembling groove 25 is opened on the top surface of the manhole cover 7, the assembling groove 25 is an inverted "convex"-shaped circular groove, the assembling groove 25 communicates with the water collecting groove 11, a cleaning ring 26 is movably inserted inside the assembling groove 25, bristles are densely arranged on the inner annular surface of the cleaning ring 26, the height of the cleaning ring 26 is smaller than the height of the bottom notch of the assembling groove 25, a pressing ring 27 is inserted at the top end of the assembling groove 25, the pressing ring 27 is an inverted "convex"-shaped annular structure, the cleaning ring 26 is clamped between the pressing ring 27 and the bottom surface of the assembling groove 25, a fixing screw 28 is screwed to the top edge of the pressing ring 27, the fixing screw 28 penetrates through the top plate of the pressing ring 27 and then is screwed to the surface of the assembling groove 25, a second rubber ring 29 is sleeved and fixed on the outer annular surface of the lifting seat 16, and the second rubber ring 29 is clamped between the lifting seat 16 and the pressing ring 27.

[0026] When the lifting seat 16 is lifted, the bottom end of the sleeve 15 is sleeved on the top end of the water delivery pipe 14, the metal mesh cover 24 is exposed out of the water collecting groove 11, and the backing plate 23 is still inserted in the water collecting groove 11. Rainwater on the ground surface not only passes through the mesh plate 19, then flows along the sleeve 15 and the water delivery pipe 14 and falls into the rainwater-sewage separation cylinder 1 from the circular drainage opening 12; a part of rainwater passes through the metal mesh cover 24 from around the water collecting groove 11 and then enters the water collecting groove 11, and the rainwater inside the water collecting groove 11 falls into the rainwater-sewage separation cylinder 1 through the oblong drainage opening 13; the problem of surface ponding caused by slow drainage speed of the rainwater inlet and blockage of the rainwater inlet in existing rainwater-sewage separation equipment is further solved; the drainage area of the manhole cover can be enlarged, thereby increasing the rainwater discharge speed. Fifth Embodiment:

[0027] Refer to the attached Figure 6 On the basis of the fourth embodiment, in order to supply energy to the electric push rod 31, a mounting frame 30 is centrally fixed on the bottom surface of the top plate of the lifting seat 16, the electric push rod 31 is fixed on the top surface of the bottom plate of the mounting frame 30, the piston rod of the electric push rod 31 penetrates through the bottom plate of the mounting frame 30, an embedding groove 32 is opened on the top surface of the lifting seat 16, the photovoltaic panel assembly 33 comprises a photovoltaic panel and an energy converter, the photovoltaic panel is fixed in the embedding groove 32, the energy converter is fixed on the bottom plate of the mounting frame 30, and the energy converter is respectively connected to the photovoltaic panel and the electric push rod 31 through two groups of wires.

[0028] The photovoltaic panel is exposed on the top of the manhole cover 7. After receiving sunlight, it converts and stores the energy in the transducer. The stored power supplies the electric push rod 31. The thickness of the photovoltaic panel is less than the depth of the mounting groove 32, thus preventing pedestrians from stepping on the photovoltaic panel. It further solves the problems of slow drainage speed of rainwater inlet and water accumulation caused by blockage of rainwater inlet in existing rainwater and sewage diversion equipment. It can expand the drainage area of ​​the manhole cover, thereby improving the rainwater discharge speed. Example 6:

[0029] Based on Example 5, refer to Appendix Figure 13 and Figure 15 In order to filter debris in the rainwater that falls into the rainwater and sewage diversion cylinder 1, an overlapping ring 42 is fixed to the inner wall of the rainwater and sewage diversion cylinder 1. An overlapping plate 43 is attached above the overlapping ring 42. The inner ring diameter of the overlapping plate 43 is smaller than that of the inner ring diameter of the overlapping ring 42. A metal mesh frame 44 is fixed to the bottom surface of the overlapping plate 43. Two handles 45 are fixed to the top surface of the overlapping plate 43. The two handles 45 are symmetrically distributed about the inner ring opening of the overlapping plate 43. A rubber ring 3 46 is fitted and fixed to the outer ring surface of the overlapping plate 43. The rubber ring 3 46 is clamped between the overlapping plate 43 and the rainwater and sewage diversion cylinder 1 and undergoes elastic deformation.

[0030] The metal mesh frame 44 collects debris from rainwater. When it is necessary to clean the debris inside the metal mesh frame 44, the manhole cover 7 is opened, and then the overlapping plate 43 and the metal mesh frame 44 are pulled out from the rainwater and sewage diversion cylinder 1 by holding the handle 45. This further solves the problems of slow drainage speed of rainwater inlets and water accumulation on the ground caused by rainwater inlet blockage in existing rainwater and sewage diversion equipment. It can expand the drainage area of ​​the manhole cover, thereby improving the rainwater discharge speed. Example 7:

[0031] Based on Example 6, a method for using an anti-clogging rainwater and sewage separation device is proposed, the method comprising the following steps: The rainwater and sewage diversion cylinder 1 is installed in the rainwater well. The municipal sewage pipe is connected to both ends of the sewage conveying pipe 2, and the municipal rainwater pipe is connected to the two rainwater pipe connecting pipes 3 on both sides of the rainwater and sewage diversion cylinder 1. Sewage is transported through the sewage conveying pipe 2, and rainwater is transported through the rainwater and sewage diversion cylinder 1 and the rainwater pipe connecting pipes 3. Rainwater on the ground falls into the rainwater and sewage diversion cylinder 1 through the reserved opening 17, the drainage round opening 12 and the oblong drainage opening 13. If there is a blockage covering the top of the screen plate 19, the screen plate 19 is repeatedly pulled out and then released, and the blockage in the mesh of the screen plate 19 is shaken off. When there is a large amount of rainwater on the ground, the switch of the electric push rod 31 is triggered. After the piston rod of the electric push rod 31 extends, the lifting seat 16 is raised, and the metal mesh cover 24 is exposed to the water collection tank 11. The rainwater on the ground enters the water collection tank 11 through the reserved opening 17 and then falls through the drainage round opening 12 and the oblong drainage opening 13. The metal mesh frame 44 collects the debris in the rainwater to prevent the debris in the rainwater from clogging the rainwater pipe connection 3.

[0032] In actual use, after the manhole cover 7 covers the opening of the rainwater and sewage diversion cylinder 1, the manhole cover 7 overlaps the retaining ring 8 to prevent the manhole cover 7 from falling. When the rubber clamp 37 is in its initial state, one end of the top support block 35 is inserted into the slot 36. At this time, the manhole cover 7 is fixed above the retaining ring 8, meaning that the manhole cover 7 will not experience any bumping or opening. When it is necessary to open the manhole cover 7, push the lever 38 with your finger to cause the support block 35 to squeeze the rubber clamp 37 until one end of the support block 35 protrudes from the slot 36. At this time, the manhole cover 7 is no longer braked. Pinch the lever 41 with your other hand to lift the manhole cover 7. The process of lifting the manhole cover 7... The connecting handle 5 rotates around the limiting shaft 6 to open; the reason for adding an elastic band 39 between the lever 38 and the storage groove 34 is to prevent debris from entering the storage groove 34 and blocking the movement of the insert 35; when the lifting seat 16 is inserted into the water collection tank 11, the sleeve 15 is fitted above the water supply pipe 14. After rainwater falls on the lifting seat 16, it passes through the mesh plate 19 and then falls along the sleeve 15 and the water supply pipe 14 through the drain hole 12 into the rainwater and sewage diversion cylinder 1. When the mesh of the mesh plate 19 becomes blocked, the connecting ring 18 is pulled upward by digging into the digging groove 21 with a finger, and the connecting ring 18 is tensioned. When the rubber interlocking ring 20 deforms and the connecting ring 18 is released, the rubber interlocking ring 20 rebounds and pulls the connecting ring 18 to strike the surface of the reserved opening 17. After repeated tensioning of the connecting ring 18, it is released, and the resulting vibration dislodging the blockage in the mesh of the screen plate 19. When the lifting seat 16 is raised, the bottom end of the sleeve 15 is fitted onto the top end of the water supply pipe 14, the metal mesh cover 24 is exposed in the water collection tank 11, and the pad 23 is still inserted in the water collection tank 11. The rainwater on the bottom surface not only passes through the screen plate 19 and then flows along the sleeve 15 and the water supply pipe 14, but also falls from the drain opening 12 into the rainwater and sewage diversion cylinder 1; a portion of the rainwater flows from the water collection tank 11... Rainwater enters the collection tank 11 through the metal mesh cover 24. Inside the collection tank 11, rainwater falls into the rainwater and sewage diversion cylinder 1 through the elongated drain outlet 13. The photovoltaic panel is exposed on the top of the manhole cover 7. After receiving sunlight, it converts and stores energy in the transducer. The stored power supplies the electric push rod 31. The thickness of the photovoltaic panel is less than the depth of the mounting groove 32, thus preventing pedestrians from stepping on the photovoltaic panel. The metal mesh frame 44 collects debris in the rainwater. When it is necessary to clean the debris inside the metal mesh frame 44, the manhole cover 7 is opened, and then the overlapping plate 43 and the metal mesh frame 44 are pulled out from the rainwater and sewage diversion cylinder 1 by holding the handle 45.
