Description

Urban Sewer Pipe Sewage Discharger

technical field

The utility model belongs to the technical field of municipal facilities and relates to a sewage discharger for urban sewer pipes.

Background technique

At present, most of the sewer pipe sewage devices used in cities adopt traditional old-fashioned castors, which are installed on the roadside of urban streets. Although this device can play a certain role in sewage discharge, it still has the following defects:

1. Due to the small area of the grate used and the small spacing between the grates, when it rains, the weeds, leaves, plastic bags and other dirt on the road will easily block the grate mouth, resulting in poor drainage;

2. Most of the sewage mixed in the sewer pipes enters the main network of urban drainage pipes, which will easily cause blockage of the main network, and the sewage will easily cause pollution of rivers and lakes after flowing into rivers and lakes through the main network;

3. Since the grate can only filter and cannot act as a seal, the odor in the sewer pipe is easy to overflow from the mouth of the grate, causing the surrounding odor to be smoky, creating conditions for the spread and prevalence of diseases.

Contents of the invention

In the course of daily work, the inventor found that the existing urban sewage pipeline sewage device has the above-mentioned defects. After design improvement, the technical problem to be solved by this utility model is to provide a kind of drainage device with smooth drainage, good sealing, and effective filtration of dirt. city sewer drainer.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is that the sewage discharger of urban sewer pipes includes a housing, the housing is composed of a body cavity and a side wall, the body cavity and the side wall are connected through a diversion groove, and the diversion groove The outlet end in the body cavity is a wedge-shaped inclined surface, and a water retaining plate is attached to the wedge-shaped inclined surface. The water retaining plate is rotatably connected with the body cavity wall above the diversion groove. A protective cover is arranged on the side of the wall close to the well cover, and drain holes are arranged on the protective cover.

The utility model adopts the urban sewer pipe sewage discharger designed by the above-mentioned technical scheme. Since the rainwater enters through the drain hole of the protective cover, the drain hole adopts a side-standing structure with a large diameter, which is not easy to accumulate water and drains smoothly; Under the condition of water flow, the outlet of the diversion tank can be closed under the action of its own gravity, thereby effectively preventing the discharge of peculiar smell in the sewer pipe; the filter basket in the cavity can effectively filter the sewer water, greatly reducing the content of dirt in the main network , reducing the pollution of rivers and lakes.

Detailed ways

Below in conjunction with accompanying drawing, the structure of the utility model urban sewer sewage drainer is described in detail.

Referring to Fig. 1, Fig. 2, the structure of the utility model urban sewer pipe sewage discharger comprises housing 1, and housing is made up of body cavity 9 and side wall body 4, and the body cavity 9 of housing adopts the three-dimensional structure of opening up and down, body cavity 9 and side wall The wall body 4 is connected through the diversion groove 6, and the outlet end of the diversion groove 6 in the body cavity 9 is a wedge-shaped inclined surface, and a water retaining plate 7 is attached to the wedge-shaped inclined surface, and the water retaining plate 7 and the body cavity wall above the diversion groove 6 Connected by rotation of the rotating shaft 5, a well cover 2 is provided at the upper opening of the housing 1, a filter basket 8 is provided at the lower opening, a protective cover 10 is provided on the side wall 4 near the well cover 2, and a drainage hole 3 is established on the protective cover 10.

When the utility model is in use, it is fixed at the water inlet on the side of the urban road. The rainwater flows into the side wall body 4 through the drainage hole 3 of the protective cover 10, and the larger sundries in the rainwater are blocked outside the protective cover 10, and the rainwater entering the side wall body 4 flows into the diversion groove 6, and the debris on it is blocked. The water plate 7 is washed away and flows into the filter basket 8, and the rainwater filtered by the filter basket 8 contains less impurities, thereby ensuring that the water flowing into rivers and lakes is not polluted. After the drainage was finished, the water retaining plate 7 was attached to the inclined surface of the water outlet end in the diversion groove 6 body cavity automatically under the effect of self gravity, thereby it was sealed to prevent the peculiar smell in the sewer pipe from leaking. Regularly open the upper opening of the body cavity 9 to remove the sundries in the filter basket 8, which is very convenient to operate.
