Novel storm sewage buoyancy cut-off device

Abstract

The invention discloses a novel storm sewage buoyancy cut-off device. An urban storm sewage pipeline is not required to be modified in a large scale, the prior storm sewage pipeline is utilized completely, and the storm sewage cut-off is achieved without external force and manual maintenance. The device comprises a cut-off device base which is fixed on a cutting channel, wherein a water outlet hole is arranged on the base, a connecting plate is fixed on the base through a shaft, a cut-off flashboard is fixed at one end of the connecting plate, a floating barrel is fixed at the other end of the connecting plate, a positioning pin is arranged on the base, a positioning slot is arranged on the connecting plate, and the positioning pin is located in the positioning slot. By the aid of the principle of buoyancy, the storm sewage cut-off is achieved through the height of the liquid level, the device can replace the flashboard, and the embedded structure of the storm sewage pipeline is solved effectively. The device is good in cut-off effect, free from manual, mechanical and electric control and maintenance, suitable to cut-off of the urban storm sewage pipeline and wide in market prospect.

Description

technical field [0001] The invention relates to the interception of rainwater and sewage in urban streets and large-scale factory rainwater pipe networks. In particular, there is no need for large-scale reconstruction of rainwater pipe networks in urban areas. On the basis of making full use of the original rainwater pipe networks, no external power and Manual maintenance is the interception device that can achieve the purpose of rainwater interception. Background technique [0002] my country is a big water-short country. In addition, with the development of the economy, the environmental pollution has become more and more serious, especially the pollution of water sources has reached a very serious level. The contradictions in the use of water resources have become more and more prominent, and there has even been competition for water resources between regions. . For this reason, the country has promulgated relevant laws and regulations to protect water resources, and rain...

Problems solved by technology

However, such treatment involves the following problems: 1. Not all the water entering the rain-sewage combined pipe network is sewage and needs to be treated. It is a waste to treat rainwater that is not sewage, which increases the treatment cost, and When rainwater and sewage that are not sewage are treated together, the concentration of sewage will decrease and the treatment effect will be reduced

2. The processing capacity of the sewage treatment plant is limited, and sometimes the processing capacity cannot keep up with the sudden large amount of rainfall. When the rainwater enters the sewage treatment plant during a heavy rainstorm, it may cause the sewage treatment plant to be paralyzed

Valves or gates require manual or electric power to open and close, and the operating cost is relatively high
