First rain diversion device capable of inducing flow velocity

Abstract

The invention discloses a first rain diversion device capable of inducing the flow velocity. The first rain diversion device capable of inducing the flow velocity comprises a well body, a water inlet pipe and a water outlet pipe are arranged on the well body, a filter cartridge is fixed on the upper portion of the inner wall of the well body, the bottom of the filter cartridge is connected with an isolated base, a first rain collecting chamber is formed by the inner wall, below the isolated base, of the well body in an enclosing mode, a water channel which is communicated with the first rain collecting chamber is formed in the isolated base, a diversion plate is fixedly connected to portion, above the isolated base, of the filter cartridge, the diversion plate is provided with a flow velocity induction structure and a connecting rope via hole, a connecting rope is connected to the flow velocity induction structure, one end of the connecting rope is fixedly connected with the flow velocity induction structure, the other end of the connecting rope penetrates through the connecting rope via hole to be fixedly connected with a seal ball, and the seal ball is matched with the water channel in a sealed mode; a first rain discarding tube is connected to the first rain collecting chamber. According to the first rain diversion device capable of inducing the flow velocity, whether discarding is conducted or not is determined by inducing the flow velocity of inflow water, first rain discarding is sufficient, waterpower is controlled automatically in the whole process, external power is not needed, operation is easy, and the first rain diversion device capable of inducing the flow velocity has the advantages of being capable of saving energy, durable and not prone to blocking.

Description

technical field [0001] The invention relates to rainwater recovery and utilization technology, in particular to an induction flow velocity primary rain diversion device. Background technique [0002] With the increase of urban air pollution and ground pollution, the pollution of rainwater runoff is becoming more and more serious, especially the initial rainwater with more pollutants (referred to as initial rain). Numerous studies at home and abroad have shown that the initial rainwater quality of runoff is very poor. The highest value of rain pollutant indicators is much higher than that of typical urban domestic sewage. Therefore, the treatment and disposal of early rain is the key technology of rainwater recycling. If the initial rain is intercepted by the network system, it uses the interception pipe network system to intercept the initial rain to the sewage pipe and send it to the sewage treatment plant for purification treatment. The rainwater pollution in the later per...

[0002] With the increase of urban air pollution and ground pollution, the pollution of rainwater runoff is becoming more and more serious, especially the initial rainwater with more pollutants (referred to as initial rain). Numerous studies at home and abroad have shown that the initial rainwater quality of runoff is very poor. The highest value of rain pollutant indicators is much higher than that of typical urban domestic sewage. Therefore, the treatment and disposal of early rain is the key technology of rainwater recycling. If the initial rain is intercepted by the network system, it uses the interception pipe network system to intercept the initial rain to the sewage pipe and send it to the sewage treatment plant for purification treatment. The rainwater pollution in the later period of the rainfall is relatively light. After pretreatment, it is directly discharged into the natural environment. However, the current initial rainwater interception facilities have the following disadvantages: 1) The structure of the interception pipe network system is complex, and operation and maintenance are difficult; 2) The equipment is easy to be blocked during the pretreatment of the later rainwater before discharge; 3) Usually, it needs to pass Electric valves and weir gates are used to intercept the flow, which consumes a lot of energy and has a short service life
