Description
Technical Field
[0001] The utility model relates to the technical field of drainage pipes, in particular to a municipal drainage pipe. Background Art
[0002] Municipal drain pipes are an indispensable part of urban infrastructure, used to collect and discharge domestic sewage, industrial wastewater and precipitation. They are usually made of different materials and are divided into rainwater pipes, sewage pipes and drainage channels according to their purpose and location. The main functions of municipal drain pipes include flood control, drainage, and collection and discharge of sewage. Through drainage channels and rainwater pipes, they can effectively discharge rainwater and groundwater out of the city, reduce the occurrence of urban waterlogging and floods, in addition, they can also timely and reliably remove domestic sewage and precipitation generated in urban areas, thereby ensuring the normal operation of urban ecosystems and the comfort and safety of residents.
[0003] At present, when using drainage pipes, it is usually necessary to install the drainage pipes in designated areas, and then discharge the domestic sewage and precipitation generated in the urban area through the drainage pipes. However, when using the drainage pipes to discharge the domestic sewage and precipitation generated in the urban area, since the domestic sewage and precipitation generated in the urban area may contain garbage and other substances, they may adhere to the inner wall of the drainage pipes, which will affect the discharge of the domestic sewage and precipitation generated in the urban area by the drainage pipes in the long run, and affect the service life of the drainage pipes. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a municipal drainage pipe, comprising a first pipe, a water inlet is arranged at the top of the first pipe, and a water outlet is arranged at the bottom of the first pipe, a second pipe is arranged in the first pipe, and the first pipe and the second pipe are provided with a cavity, a connecting block is movably connected in the second pipe, and the connecting block is made of elastic material, a brush is arranged on the outer surface of the connecting block, two groups of fixed blocks are fixedly connected in the cavity, a rotating shaft is arranged between each group of the fixed blocks, a sleeve is movably connected to the outer surface of each rotating shaft, and a coil spring is arranged between the rotating shaft and the sleeve, one end of a rope is fixedly connected to the outer surface of each sleeve, and the other end of the rope is fixedly connected to the top of the connecting block.
[0006] By adopting the above technical solution, a connecting block is provided. When domestic sewage and precipitation enter the second pipe through the water inlet, the impact of the water generates a thrust on the connecting block, causing the connecting block to move toward the water outlet. The connecting block then simultaneously drives the brush to move toward the water outlet, which is convenient for cleaning the inner wall of the second pipe. At the same time, when the connecting block is moved by the thrust, the rope can be pulled synchronously, and after the thrust received by the connecting block disappears, the sleeve can be driven to return to its original position by the winding spring, thereby winding and storing the rope, so that the connecting block is restored to its original position, which is beneficial for driving the connecting block and the brush to reciprocate in the second sleeve through this structure, which is convenient for better cleaning of the inner wall of the second pipe, thereby extending the service life of the drainage pipe.
[0007] The utility model is further configured such that a group of first holes are arranged in the second pipe, and oil-sealed linear bearings are arranged in the first holes, and the rope moves in the oil-sealed linear bearings.
[0008] By adopting the above technical solution, it is beneficial for the rope to move in the oil-sealed linear bearing, thereby reducing the friction between the rope and the second pipe, which is convenient for extending the service life of the rope. At the same time, the oil-sealed linear bearing has a waterproof effect, which can prevent water from entering the cavity through the first hole, thereby affecting the use of the drainage pipe.
[0009] The utility model is further configured that a groove is provided on the top of the connecting block, and a plurality of second holes are provided in the groove.
[0010] By adopting the above technical solution, when domestic sewage and precipitation enter the drain pipe through the water inlet, water can flow through the second hole in the groove, which is convenient for better discharge of sewage. At the same time, the setting of the groove is conducive to increasing the impact of water on the connecting block, so as to better drive the connecting block to move in the second pipe.
[0011] The utility model is further configured that a through hole is provided in the middle of the connecting block.
[0012] By adopting the above technical solution, it is beneficial to improve the drainage efficiency of the drainage pipe through the through hole, avoid clogging of the drainage pipe due to slow drainage efficiency, thereby affecting the discharge of domestic sewage and precipitation in the urban area.
[0013] The utility model is further configured such that the brush is in close contact with the inner wall of the second pipe.
[0014] By adopting the above technical solution, the inner wall of the second pipe can be better cleaned by having the brush close to the inner wall of the second pipe, thereby extending the service life of the drainage pipe.
[0015] In summary, the utility model mainly has the following beneficial effects:
[0016] The utility model is provided with a connecting block. When domestic sewage and precipitation enter the second pipe through the water inlet, the impact of water generates a thrust on the connecting block, so that the connecting block drives the brush to move toward the water outlet, which is convenient for cleaning the inner wall of the second pipe. At the same time, when the connecting block is moved by the thrust, the rope can be pulled synchronously, and after the thrust received by the connecting block disappears, the sleeve can be driven to return to its original position by the winding spring, so that the rope can be wound and stored, so that the connecting block is restored to its original position, which is conducive to driving the connecting block and the brush to reciprocate in the second sleeve through this structure, which is convenient for better cleaning the inner wall of the second pipe, thereby extending the service life of the drainage pipe.
