Description

A rain and sewage diversion and interception well that realizes self-control through buoyancy and leverage

technical field

The utility model relates to the technical field of interception wells, in particular to a rain and sewage diversion interception well which realizes self-control through buoyancy and levers.

Background technique

Rain and sewage diversion and interception wells are one of the most effective measures for water environment treatment and improvement at present. The problem of sun rooms built privately on the roofs of some old residential buildings often occurs, and residents’ activities on the roofs cause The domestic sewage is directly discharged to the roof of the building, and the sewage is indirectly discharged into the rainwater riser along the rain gutter. Some residents even directly connect the domestic sewage from the sun room to the rainwater riser, resulting in rain pollution in the rainwater system of the diversion system. Hybrid problem.

During the dry season, the domestic sewage generated on the roof of the building is transported to the rainwater system of the community along with the rainwater riser, and then discharged into the surrounding river system, polluting the water body and destroying the water ecosystem.

During the rainy season, there is both domestic sewage and rainwater on the roof, and the mixed sewage is also directly discharged into the river. During the rain and sewage diversion renovation project, it was found that the roof, especially the high-rise (more than 7 floors) is usually built without permission. It is very difficult to reconstruct the problem of mixed rain and sewage caused by the building. It is necessary to destroy the parapet of the roof to completely divert the sewage from the roof to the sewage riser on the facade of the building. However, this is not good for the safety of workers working at heights. The damaged building structure will cause great disturbance to the residents. It is not recommended to go directly to the roof to divert and renovate. Instead, add an interception well at the bottom of the rainwater standpipe where the building is mixed to separate the sewage and rainwater from the source. Reduce the degree of pollution to the surrounding water environment.

In the existing interception wells, electric devices or hydraulic devices are usually used for interception. Due to the long-term sewage flow in the interception wells, the electric or hydraulic equipment used in sewage often breaks down, and general electric or hydraulic equipment, It will be blocked by debris and cause water leakage, resulting in poor sealing of electric or hydraulic devices and inconvenience in later management and maintenance. Therefore, the applicant has developed a rain and sewage diversion and interception well that utilizes buoyancy and leverage to automatically control the diversion.

At present, there is a Chinese patent authorization announcement number of CN202248219U which discloses an interception well with a lever-type interception gate. This patent realizes the rain and sewage automatic drainage through the cooperation between the gate 6, the lever 7, the floating bucket 8 and the counterweight 9. Diversion, but the disadvantage of this patent is that the sewage and rainwater are in the same space, which is easy to cause sewage to be discharged into the rainwater discharge pipe or rainwater to be discharged into the sewage intercepting pipe, and the above-mentioned pollution problems will also occur if the sewage and rainwater are not separated.

In addition, there is a Chinese patent authorization announcement number of CN214460998U which discloses a rain and sewage diversion and interception well that realizes self-control through buoyancy. The disadvantage is that the sewage and rainwater are in the same space, and there is also the problem of not separating the sewage and rainwater, and the above-mentioned pollution also occurs.

In a preferred embodiment of the present utility model, the well body is arranged in a square structure.

Due to the adoption of the above technical scheme, the beneficial effect of the utility model is that the utility model realizes the automatic control of rainwater and sewage diversion under the action of the buoyancy and the principle of leverage. The ram is lifted to the open state, and the sewage mixed with the rainwater standpipe can only flow into the sewage drainage pipe due to the existence of the interception weir; during the rainy season, a large amount of rainwater pours into the well body, and the rainwater turns over the interception weir and enters the buoy tank. The water level in the buoy tank rises, under the action of buoyancy, the buoy rises, and the gate at the sewage drain pipe closes. At this time, a large amount of rainwater can only enter the rainwater drain pipe. After the rain peak, the water in the buoy tank passes through the buoy tank drain pipe Discharged to the downstream rainwater well, the water level drops, the buoys drop, and the ram automatically rises to return to its original position. The entire rain and sewage separation process is automatically controlled based on buoyancy and leverage principles, and does not involve other mechanical power or human operation. The structure is simple and the operation is stable.
