Description

Technical Field

[0001] The utility model relates to the technical field of sewage pipes, in particular to a rain and sewage pipe with anti-blocking function. Background Technique

[0002] In the rainy season, the hydrophobic system is like the blood vessels of a city. Only by being able to discharge and guide rainwater in an orderly manner can floods be prevented.

[0003] With the development of society, there is a lot of garbage in cities. Once the water flushes the garbage to the upper end of the rain and sewage pipe, the traditional water inlet generally uses a grate fence and a manhole cover as the cover plate, and it is very easy to block the water inlet holes of the cover plate. Once the hydrophobic system of the city is blocked and not cleaned for a long time, it will lead to more serious flood disasters.

[0004] Therefore, it is necessary to provide a rain and sewage pipe with anti-blocking function to avoid impurities entering the through holes and causing blockage, and to avoid the problem of floods caused by sewage impurities blocking the through holes. Content of the Utility Model

[0005] The purpose of the utility model is to provide a rain and sewage pipe with anti-blocking function to solve the above problems.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A rain and sewage pipe with anti-blocking function of the utility model includes a main pipe and a water inlet pipe. The bottom of the water inlet pipe is vertically connected to the main pipe. The top of the water inlet pipe is a circular flared opening. A manhole cover is arranged in the circular flared opening. At least two water inlet holes are opened on the manhole cover. A cleaning component is arranged below the manhole cover. The cleaning component is installed on the inner wall of the water inlet pipe. The cleaning component includes a mounting frame and circular brushes connected to the mounting frame corresponding to the number of the water inlet holes. The end of the mounting frame is slidably connected to the inner wall of the water inlet pipe. A floating ball is connected below the mounting frame through a connecting rod.

[0008] Further, four water inlet holes are opened on the manhole cover, and four circular brushes are provided.

[0009] Further, the circular brush is sleeved on a rotating shaft, and both ends of the rotating shaft are connected to the mounting frame through bearing seats.

[0010] Further, the included angle between two adjacent circular brushes is 90°, and the mounting frame is in a cross shape.

[0011] Further, a plug rod is connected to the end of the mounting frame. The plug rod is inserted into a strip-shaped groove formed in the inner wall of the water discharge pipe. Slide rods are arranged on both sides of the plug rod, and the slide rods are slidably connected to sliding grooves formed in the inner wall of the strip-shaped groove.

[0012] Further, the vertical central axis of the circular brush is located on one side of the center of the water discharge hole.

[0013] Compared with the prior art, the beneficial technical effects of the present utility model are as follows:

[0014] When the water level rises, the present utility model can drive the circular brush to rise through the floating ball, so that the top of the brush passes through the water discharge hole. Then, through the impact of the water above the manhole cover on the circular brush, the sundries blocking the water discharge hole can be brushed down, avoiding the problem of flood caused by the blockage of the water discharge hole by sewage impurities.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] As Figures 1-4 shown, a rain and sewage pipe for preventing blockage includes a main pipe 1 and a water discharge pipe 2. The bottom of the water discharge pipe 2 is vertically connected to the main pipe 1.

[0022] The top of the water discharge pipe 2 is a circular flared opening. A manhole cover 3 is arranged in the circular flared opening, and four water discharge holes 4 are formed in the manhole cover 3.

[0023] A cleaning component is arranged below the manhole cover 3, and the cleaning component is installed on the inner wall of the water discharge pipe 2.

[0024] The cleaning component includes a mounting frame 5 and circular brushes 6 connected to the mounting frame 5 and corresponding to the number of the water drainage holes 4. The circular brushes 6 are sleeved on a rotating shaft, and both ends of the rotating shaft are connected to the mounting frame 5 through bearing seats 9. The included angle between two adjacent circular brushes 6 is 90°, and the mounting frame 5 is in a cross shape. The end of the mounting frame 5 is slidably connected to the inner wall of the water drainage pipe 2. The end of the mounting frame 5 is connected with an insertion rod 10, and the insertion rod 10 is inserted into a strip-shaped groove 11 opened on the inner wall of the water drainage pipe 2. Slide rods 12 are arranged on both sides of the insertion rod 10, and the slide rods 12 are slidably connected to slide grooves 13 opened on the inner wall of the strip-shaped groove 11. A floating ball 8 is connected below the mounting frame 5 through a connecting rod 7.

[0025] The vertical central axis of the circular brush 6 is located on one side of the center of the water drainage hole 4, so as to prevent the circular brush 6 from completely blocking the upward water drainage hole 4 after rising and affecting the water drainage effect.
