[0010] Preferably, when the other end of the cam corresponding to the tip vertically abuts against the surface of the semicircular abutment block, the top of the filter plate remains flush with the bottom end of the water inlet.

[0011] Preferably, when the tip of the cam vertically abuts against the surface of the semicircular abutment block, the top of the filter plate remains flush with the top end of the water inlet.

[0012] The present invention also provides a method for using a sewage well leakage plugging device, comprising the following steps:

DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0028] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0029] In the description of the present invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. to indicate directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0030] Reference Figure 1-Figure 8, a sewage well leakage plugging device comprises a well frame 1 and a well cover 2, a connecting groove 11 is provided on the top of the well frame 1, when the well cover 2 is embedded in and closes the connecting groove 11, it can be used to seal the top opening of the well frame 1, and a plurality of water inlets 21 are arranged on the top of the well cover 2, when it rains, it helps the accumulated water on the ground to enter the well through the water inlet 21 for discharge, at the same time, considering that when the accumulated water on the ground is discharged, impurities such as leaves, plastic bags, etc. on the ground may also flow into the well through the water inlet 21 with the flow of rainwater, causing blockage of the water inlet 21 and the well, so based on this problem, a matching filter plate 3 is connected in each water inlet 21, when rainwater flows through the filter plate 3, debris will be intercepted on the surface of the filter plate 3, and the clean water flow can continue to flow downward through the pores of the filter plate 3 and enter the well for discharge, this design not only avoids the blockage and accumulation of debris, but also improves the drainage efficiency and reduces the burden of subsequent cleaning work.

[0031] In the above technical solution, in order to facilitate the subsequent cover removal operation of the manhole cover 2 during maintenance, the top edge of the manhole cover 2 is provided with a plurality of pulling grooves 22 distributed in a circular pattern. These pulling grooves 22 not only provide convenient holding points, but also increase the stability and safety when removing the cover. In order to further improve the convenience of the cover removal operation, the inner wall of the pulling groove 22 is provided with an extension groove 23. The design of the extension groove 23 can increase the contact area between the hand and the manhole cover 2, so that the manhole cover 2 can be held more firmly when removing the cover to prevent accidental injuries caused by slipping. The extension groove 23 can also serve as an interface for engaging with auxiliary tools such as hooks and ropes. When mechanical assistance is required to remove the cover, one end of the hook or rope can be fixed in the extension groove 23, and the other end is controlled by the operator, thereby realizing a labor-saving cover removal operation.

[0032] Further, based on the above embodiment, referring to Figure 1-Figure 5 and Figure 7Since the water inlet 21 is always in an open state, although it is convenient for rainwater on the ground to enter the well through the water inlet 21 for discharge, it will also cause the odor in the well to escape from the water inlet 21 and affect the air environment. Therefore, a corresponding drainage unit 4 is provided at the bottom end of the water inlet 21, which is used to reduce the escape of odor in the well without affecting the discharge of rainwater. The drainage unit 4 includes an upper shell 41, and a drainage groove 42 adapted to the water inlet 21 is connected between the top and the bottom of the upper shell 41. A lower shell 43 is fixed to the bottom of the upper shell 41, and a cylindrical groove 44 connected to the bottom end of the drainage groove 42 is provided in the lower shell 43. A connecting shaft 45 is rotatably provided on the lower shell 43, and a plurality of blades 46 distributed in a circle and in contact with the inner wall of the cylindrical groove 44 are fixed on the connecting shaft 45. The bottom of the lower shell 43 is provided with a cylindrical groove 44 connected to the bottom end of the cylindrical groove 44. The drainage port 47 connected to the groove 44, the channel connecting the drainage groove 42 and the cylindrical groove 44 in the drainage unit 4 corresponds to the bottom port of the water inlet 21. When the accumulated water on the ground flows in from the water inlet 21 on the manhole cover 2, the water will first pass through the drainage groove 42 and smoothly enter the cylindrical groove 44. The blades 46 are distributed in a circle and fit tightly with the inner wall of the cylindrical groove 44. Therefore, when the water flow hits the blades 46, sufficient torque will be generated to drive the connecting shaft 45 to rotate on the lower shell 43. As the connecting shaft 45 rotates, the blades 46 will also rotate along the inner wall of the cylindrical groove 44, and the water entering the cylindrical groove 44 will enter the well through the drainage port 47 for discharge. This design not only efficiently completes the drainage task, but also avoids the escape of odor in the well, thereby improving the air quality of the surrounding environment.

[0033] At the same time, in order to facilitate the subsequent maintenance of the drainage unit 4, a connecting edge 48 is extended from the top edge of the upper shell 41, and a plurality of connecting holes 49 are provided on the connecting edge 48. A matching locking portion 410 passes through the connecting hole 49, and a locking groove 24 is provided at the bottom of the manhole cover 2 for fixing the locking portion 410. By adopting a locking portion 410 with a screw structure and cooperating with the locking groove 24 with a threaded structure, the locking portion 410 can be easily screwed in or out of the locking groove 24, thereby realizing the rapid disassembly and installation of the upper shell 41, so that the drainage unit 4 has the characteristics of being detachable and easy to replace during subsequent maintenance.

[0034] In a preferred embodiment, referring to Figure 1-Figure 4 and Figure 7When the filter plate 3 is slidably connected to the inner wall of the water inlet 21, an elastic support portion 31 is provided at the bottom center of the filter plate 3, and a pair of semicircular abutment blocks 32 are fixed at the bottom of the filter plate 3. A lifting mechanism 33 that is linked to the connecting shaft 45 is attached to the surface of the semicircular abutment blocks 32. The lifting mechanism 33 is used to cooperate with the filter plate 3 to rotate with the help of the connecting shaft 45, so that the filter plate 3 can make intermittent reciprocating movements up and down along the inner wall of the water inlet 21. The elastic support portion 31 includes a spring 311 fixed at the bottom center of the filter plate 3, and a circular support block is fixed at the bottom end of the spring 311. 312, a plurality of connecting strips 313 fixed to the inner wall of the drainage groove 42 are fixed on the circular support block 312, the lifting mechanism 33 includes a pair of connecting shafts 331 rotatably arranged on the upper shell 41, one end of the connecting shaft 331 located in the drainage groove 42 is fixed with a cam 332 fitted with the semicircular interference block 32, and one end of the connecting shaft 331 located outside the upper shell 41 is fixed with a pulley 333, the surface of the pulley 333 is connected with a matching transmission toothed belt 334, and the inner wall of the transmission toothed belt 334 is connected with a pulley 335 fixed to the end of the connecting shaft 45.

[0035] The above technical scheme takes into account that if the filter plate 3 is fixedly arranged in the water inlet 21, the debris flowing in the rainwater will always adhere to the surface of the filter plate 3. As the debris gathers, the filter plate 3 with such a static design may easily block the pores on the surface of the filter plate 3, thereby reducing the drainage efficiency. Therefore, based on this problem, a lifting mechanism 33 is designed between the filter plate 3 and the connecting shaft 1 45, so that the force of the water flow can be used to directly drive the blade 46 to rotate. The blade 46 is connected to the connecting shaft 1 45, so the connecting shaft 1 45 also rotates therewith. This rotational motion is mutually transmitted through the pulley 1 333, the transmission toothed belt 334 and the pulley 2 335, and finally drives the connecting shaft 2 331 to rotate, thereby realizing the cam 332 to rotate along a semicircle. The surface of the resistance block 32 rotates, so that the semicircular resistance block 32 drives the filter plate 3 to make up and down reciprocating motion in the water inlet 21 under the cooperation of the rotation of the cam 332 and the spring 311. This dynamic filtering process will cause disturbance of the water flow. This disturbance not only helps to break the laminar flow state in the water flow and form more turbulence and eddy currents, but the turbulence and eddy currents can more effectively disperse the impurities in the water and bring them to the vicinity of the filter plate 3, further increasing the chance of impurities being intercepted, and at the same time can automatically shake off the impurities and particulate matter attached to the surface of the filter plate 3, which greatly reduces the risk of the filter plate 3 being blocked. Once the filter plate 3 remains unobstructed, the water flow can flow more smoothly through the filter plate 3 into the well, thereby improving the overall drainage efficiency.

[0036] In a preferred embodiment, referring to Figure 1 and Figure 2When the other end of the cam 332 corresponding to the tip vertically contacts the surface of the semicircular contact block 32, the top of the filter plate 3 remains flush with the bottom end of the water inlet 21, that is, this process corresponds to the initial state of the filter plate 3 at the water inlet 21. In non-rainy weather, the filter plate 3 maintains a certain distance from the top end of the water inlet 21, which means that pedestrians or vehicles will hardly have direct contact with the filter plate 3. Compared with some traditional filter plates 3 arranged parallel to the top of the water inlet 21, the wear on the surface of the filter plate 3 caused by frequent contact is avoided, thereby extending the service life of the filter plate 3, because the worn surface of the filter plate 3 may become rough, which makes it easier for impurities to adhere to its surface. Over time, these impurities will gradually accumulate and block the filter plate 3, resulting in poor water flow or even complete blockage. Therefore, this design can not only improve the filtering effect and avoid the risk of blockage, but also improve the drainage efficiency.

[0037] In a preferred embodiment, referring to Figure 7 When the tip of the cam 332 vertically contacts the surface of the semicircular contact block 32, the top of the filter plate 3 is flush with the top end of the water inlet 21. This design state is different from the initial position when it is not raining, and is used to maximize the use of rainfall conditions. As rainwater flows in, the blades 46 are acted upon by the force of the water flow, thereby driving the connecting shaft 45 to rotate. This power is transmitted to the lifting mechanism 33, causing the filter plate 3 to intermittently move up and down inside the water inlet 21. In this dynamic working mode, the filter plate 3 can not only effectively intercept Impurities in rainwater, and because the top of the filter plate 3 is flush with the top end of the water inlet 21 and forms a consistent parallel state with the ground, this design cleverly utilizes the rainwater flowing on the ground. When the rainwater flows through the surface of the filter plate 3, it can smoothly wash away the debris attached to it, thereby keeping the surface of the filter plate 3 continuously clean. This self-cleaning mechanism significantly reduces the risk of clogging of the filter plate 3, improves the overall efficiency of the drainage system, and ensures that rainwater can quickly and smoothly pass through the filter plate 3 into the well, further improving the drainage efficiency.

[0038] The present invention also provides a method for using a sewage well leakage plugging device, comprising the following steps:

[0039] S1, align the manhole cover 2 with the connection groove 11 on the top opening of the manhole frame 1, and then slowly insert the manhole cover 2 into the connection groove 11 to complete the blocking of the top opening of the manhole frame 1 by the manhole cover 2;

[0040] S2. When rainwater or sewage enters the manhole cover 2 through the water inlet 21, it will first be filtered by the filter plate 3 to remove the debris flowing in the water;

[0041] S3. The filtered water flows into the drainage groove 42 and flows along the drainage groove 42 to the cylindrical groove 44. In the cylindrical groove 44, the water flows impact the blades 46, driving the connecting shaft 45 and the blades 46 to rotate. The water flows finally through the drainage port 47 and is discharged into the sewage well or the subsequent drainage pipe.

[0042] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which are equivalent modifications and improvements made to the above embodiments based on the essential technology of the present invention, and all of them belong to the protection scope of the present invention.
