Embodiment Construction

[0014] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0015] In order to clearly describe the content of the invention, this patent application uses the orientation words "up", "down", "left" and "right" to distinguish, and the "up", "down", "left" and "right" are based on the above It is determined by the layout orientation of the drawings. In actual use, if the viewing angle changes, the orientation name will change accordingly, which cannot be regarded as a limitation on the scope of patent protection.

[0016] like figure 1 and image 3 As shown, the present invention includes a rainwater distribution tank 1, an initial rainwater storage tank 5, a switching device 6 and a delay device 7, and the initial rainwater storage tank 5 is located directly below the rainwater distribution tank 1;

[0017] The opening at the left end of the bottom of the rainwater distribution tank 1 is connected downward to the ini...

Abstract

The invention discloses an automatic initial rainwater diversion device, and belongs to the technical field of rainwater separation. The automatic initial rainwater diversion device comprises a rainwater diversion pool, an initial rainwater storage tank, a switching device and a time delay device, wherein the initial rainwater storage tank is located under the rainwater diversion pool; an initial rainwater channel is located in the left side of the initial rainwater storage tank; a middle-later rainwater inlet is formed in the right side wall of the rainwater diversion pool, and a middle-later rainwater channel is vertically and downwards arranged in the right side of the initial rainwater storage tank; the switching device is arranged on a partition wall between the initial rainwater channel and the initial rainwater storage tank; and the time delay device is installed between the middle-later rainwater channel and the initial rainwater storage tank. The automatic initial rainwater diversion device has the technical effects that automatic diversion of initial rainwater and middle and later rainwater is realized, so that the initial rainwater is collected and treated, and the middle and later rainwater is collected and reused; and after runoff is finished, the device can automatically recover to an initial state, manual control is not needed, and energy consumption is avoided.

Description

technical field [0001] The invention belongs to the technical field of rainwater separation, and in particular relates to an automatic diversion device for initial rainwater. Background technique [0002] At present, the shortage of water resources has become a global problem, and recycling rainwater can effectively relieve water pressure. However, there is a large amount of polluting gas dissolved in the initial rainwater, and when it falls to the ground, it will contain a large amount of organic matter, pathogens, suspended solids and other pollutants due to the washing of roofs and roads. The pollution degree is usually higher than that of ordinary urban sewage. The processing cost is high, so it needs to be discarded. [0003] How to completely separate the initial rainwater from the later rainwater is a major technical problem that needs to be faced. At present, there are mainly the following types of early rainwater abandonment methods: high and low water level initia...
