AI Technical Summary
Existing drainage devices are prone to clogging when used, and the filter needs to be removed for cleaning or replacement, resulting in the water flow being unable to ensure the filtration effect. Especially during construction, there is a lot of garbage, which is prone to clogging the water pipes from deep, making it difficult to clean.
An auxiliary drainage structure for construction was designed, and a secondary filter structure that is easy to disassemble. The water flow enters the funnel through the inclined hopper and is double-layered filtered by the circular filter plate and the filter net. When the upper filter plate is blocked, the lower filter net is directly filtered, which is also convenient for disassembly and cleaning.
It realizes convenient disassembly and cleaning, avoids the reduction of filtration effect caused by water flow blockage, ensures the service life of the water pipe, is simple in structure and low in cost.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drainage assistance, in particular to an auxiliary drainage structure for building construction. Background Art
[0002] During construction, it is necessary to set up pipes for water supply and drainage. During drainage, the water flow in the water supply and drainage pipes contains a large amount of domestic garbage. This requires a filter to be set up in the pipe to block the garbage to prevent the garbage from entering large underground deep pipes such as the main water pipe. However, as time goes by, the garbage that is constantly blocked by the filter will cause blockage in the pipe, hindering the flow of drainage water. In view of this, we propose a building water supply and drainage anti-blocking device.
[0003] In the process of realizing the utility model, the inventor discovered that the prior art had the following problems: currently available drainage devices usually have a filter screen and a drain valve that can be separated, but blockage problems are inevitable during use, and the blocked filter screen needs to be cleaned or replaced. At this time, the existing filter screen needs to be disassembled, and the blocked water flow will flow into the pipe after being opened. This batch of water flow cannot guarantee its filtering effect, especially when there is a lot of garbage during construction, which will block the water pipe from deep inside and make it more difficult to clean. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides an auxiliary drainage structure for construction, which solves the problem that the existing drainage device is usually a filter screen and a drain valve that can be separated, but it is inevitable that there will be blockage problems during use, and the blocked filter screen needs to be cleaned or replaced. At this time, the existing filter screen needs to be disassembled, and the blocked water flow will flow into the pipe after being opened. This batch of water flow cannot guarantee its filtering effect, especially when there is a lot of garbage during construction, which will block the water pipe from deep inside, making it more difficult to clean.
[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: an auxiliary drainage structure for construction, including an outer shell, the shape of the outer shell is cylindrical, a rubber ring is provided on the upper part of the outer wall of the outer shell, a pair of springs are provided on the inner wall of the outer shell, a pair of arc rods are hinged on the inner wall of the outer shell, a pair of the arc rods are respectively connected to a pair of the springs, a limiting annular plate is provided between the inner wall surfaces of the outer shell, a funnel is placed in the outer shell, a straight cylinder is provided at the lower end of the funnel, and a filter is provided in the straight cylinder.
[0006] Preferably, a circular filter plate is placed in the funnel, and a buckle is provided on the upper wall surface of the circular filter plate.
[0007] Preferably, a pair of protrusions are provided on the upper portion of the inner wall surface of the funnel.
[0008] Preferably, an inclined hopper is provided on the upper wall surface of the rubber ring.
[0009] Beneficial Effects
[0010] The utility model provides an auxiliary drainage structure for construction. The utility model is designed with a secondary filtering structure that can be easily disassembled. When in use, water flows into the drain through the inclined hopper and is filtered by the circular filter plate. The filtered water is filtered again by the filter screen. The filtering degree of the filter screen is the same as that of the circular filter plate, so the filter screen will not be blocked. When the circular filter plate located on the upper layer is seriously blocked, the circular filter plate is picked up, and the water flow is directly filtered by the filter screen. When there is no water flow, the filter screen is cleaned to ensure that there is no blockage inside the filter screen, and the funnel is inserted into the shell again. The device can be easily disassembled and realizes secondary filtration. After the blocked layer of filtration is disassembled, the second layer of filtration takes effect, avoiding the part of the water flow containing impurities entering the water pipe due to water blockage and cleaning, thereby ensuring the service life of the sewer pipe, with a simple structure and low cost.
