A rainwater collection device

Abstract

The present invention relates to a rainwater collection device, comprising a water collecting and filtering residue mechanism and a rainwater storage tank, the water collecting and filtering residue mechanism includes a top support plate with a drain hole in the middle, a central water collecting ring located below the drain hole, and a The lower water collecting barrel, the diversion groove, and the water collecting top cover assembly under the middle water collecting ring, the upper end of the diversion groove is connected to the wall of the drain through hole, and the lower end is connected to the upper end surface of the middle water collecting ring, The upper end of the lower water collection bucket is connected to the inner hole of the middle water collection ring, the side wall of the lower water collection bucket is provided with a water outlet opening, and the water collection top cover assembly includes a top cover cover plate, a water inlet inclined pipe and a top cover ventilation pipe , the lower ends of the inclined water inlet pipe and the top cover ventilation pipe are connected to the top cover cover plate, the upper end of the water inlet inclined pipe is connected with the water outlet opening, the upper end of the top cover ventilation pipe is higher than the top support ring, and the rainwater The upper end of the storage tank is sealed and connected with the top cover plate, and the lower end of the inclined water inlet pipe and the top cover ventilation pipe are all communicated with the inside of the rainwater storage tank.

Description

technical field [0001] The invention relates to the field of municipal engineering, in particular to a rainwater collection device. Background technique [0002] Urban runoff pollution assessment is of great significance in the fields of municipal engineering and environmental engineering. Runoff pollution needs to be obtained through the use of surface runoff. However, because runoff is affected by uncertain factors such as weather, it is difficult to continue the collection work. In addition, when it comes to the first rain pollution and the change of pollution with rainfall, the accuracy of sampling needs to be further improved. [0003] At present, the development of rainwater sampling work and sampling devices is backward. At this stage, water is collected manually at the outlet of the sewer pipe or a mechanical turntable on the roadside plus a pumping device to collect water samples. The collection effect is limited and it is inconvenient to use. Large-scale deploymen...

[0003] At present, the development of rainwater sampling work and sampling devices is backward. At this stage, water is collected manually at the outlet of the sewer pipe or a mechanical turntable on the roadside plus a pumping device to collect water samples. The collection effect is limited and it is inconvenient to use. Large-scale deployment, and manual water sampling cannot collect early rain pollution in the first place

In addition, when time-segmented collection is required, it is difficult to guarantee the time-sharing accuracy
