Description

Technical Field

[0001] The utility model belongs to the technical field of sewage discharge devices, and in particular relates to a sewage discharge device for water supply and drainage engineering. Background Art

[0002] Engineering used for water supply, wastewater discharge and water quality improvement is referred to as water supply and drainage engineering. It is divided into water supply engineering and drainage engineering. Water supply is sometimes also called water supply. The earliest water supply engineering mostly refers to public water supply engineering in cities. However, in modern times, this term has developed into water supply engineering for industry, agricultural irrigation and other water use. The sewage discharge device of the water supply and drainage engineering with application number CN202321705200.8 includes a filter box connected to the first sewage pipe and the second sewage pipe, and a collecting box is provided on one side outside the filter box. A sewage outlet and a water outlet are connected between the two. A first mounting frame and a second mounting frame are respectively set in the filter box and the collecting box. The lower end of the first mounting frame is clamped with a first limit block provided on the lower end surface of the filter screen. A ring-shaped electric rail with a guide block is provided on one side of the first mounting frame for sliding. A brush in contact with the filter screen is provided on the guide block. A baffle with a water hole is fixedly connected to the lower end of the second mounting frame, which can remove debris on the filter screen and improve the filtering efficiency, and avoid wasting water resources. However, there are the following defects:

[0003] (1) Although the above-mentioned sewage discharge device for water supply and drainage projects achieves the filtering of debris through structures such as filter boxes, in actual drainage, sewage enters the filter box through the first sewage pipe. At this time, the debris carried by the sewage will adhere to the inner wall of the sewage pipe, causing the sewage pipe to be blocked. Due to the narrow inner wall of the pipe, it is not easy to clean in time, which in turn affects the sewage discharge. For this reason, we propose a sewage discharge device for water supply and drainage projects. Utility Model Content

[0004] The utility model aims to provide a sewage discharge device for water supply and drainage engineering, so as to solve the problem that the sewage discharge pipe of the sewage discharge device proposed in the above background technology is easily blocked and cannot be cleaned in time, which affects sewage discharge.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sewage discharge device for water supply and drainage engineering, including a sewage filter assembly, on which a first sewage pipe and a second sewage pipe are respectively arranged, a mounting frame is fixed inside the first sewage pipe, an end column is inlaid on the mounting frame through rotation, one end of the end column is connected to a rotating rod, a scraper is fixed to the side wall of the rotating rod, and the other end of the end column is connected to a turbine assembly.

[0006] Preferably, the scraper is provided with drag reducing holes on its surface, and the hole shape of the drag reducing holes is a rectangular structure.

[0007] Preferably, a rubber strip is provided between the scraper and the inner wall of the first sewage discharge pipe, and the rubber strip is fixed on the surface of the scraper.

[0008] Preferably, the longitudinal section of the end column is a circular structure, and the cross section of the end column is an I-shaped structure.

[0009] Preferably, central axes of the end column, the rotating rod and the turbine assembly coincide with each other.

[0010] Preferably, the cross section of the end column is an I-shaped structure, the inner end surface of the end column is provided with a ball groove, and the ball groove is inlaid with a ball.

[0011] Preferably, ribs are commonly connected between the two sides of the mounting frame and the first sewage pipe, and the longitudinal section of the ribs is a triangular structure.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) The turbine assembly and the scraper are assembled in the first sewage pipe through the designed mounting frame, end column, rotating rod, scraper and turbine assembly. When the sewage is input into the sewage filter assembly through the first sewage pipe, the sewage has an impact effect on the turbine assembly, thereby driving the turbine assembly to rotate. The turbine assembly drives the rotating rod to rotate, so that the scraper rotates in the first sewage pipe, and the stains attached to the inner wall of the first sewage pipe are cleaned in time, effectively avoiding the blockage in the pipe that cannot be cleaned in time and affects the sewage discharge effect. The designed drag reduction holes ensure that part of the sewage flows through the drag reduction holes during the rotation of the scraper, thereby reducing the resistance to the scraper. The designed rubber strip is installed at the end of the scraper. The rubber strip has good flexibility and deformation ability, thereby ensuring that the scraping surface fits more closely, further improving the cleaning effect of the inner wall of the sewage pipe. The designed ball bearing plays a lubricating role, reduces the friction resistance between the end column and the mounting frame, and makes its rotation smoother. BRIEF DESCRIPTION OF THE DRAWINGS
