Anti-garbage rainwater collection device

Abstract

The invention relates to the field of urban rainwater drainage, in particular to a rainwater collection device capable of preventing ground garbage from entering a rainwater system. The rainwater collection device comprises a bilayer rainwater strainer body which comprises an upper-layer strainer supported by a frame, a rolling wheel connected with an L-shaped supporting rebar is suspended on theundersurface of the upper-layer strainer, a lower-layer strainer is put on the rolling wheel, and a metal push-pull rod penetrating a slotted hole of the upper-layer strainer and convenient to realizesliding dislocation is connected on the lower-layer strainer; one end of the lower-layer strainer is connected to a transmission device and a signal receiver buried in covering soil; electric signalsof a central control chamber are transmitted to a transmission device through a signal receiver to control the lower-layer strainer to realize moving malposition of one slotted hole along the upper-layer strainer. A closed face is formed in sunny days to block garbage from entering a rainwater port; in rainy days, an orifice of the lower-layer strainer is aligned to the upper-layer strainer to realize rainwater collection; after it stops raining, the lower-layer strainer is closed to realize garbage blocking.

Description

technical field [0001] The invention relates to the technical field of urban road rainwater drainage, in particular to a double-layer rainwater grate, in particular to a rainwater grate capable of preventing daily road cleaning or human-injected garbage from entering the rainwater outlet without affecting the normal use function. Background technique [0002] According to the requirements of CJ343-2010 "Water Quality Standards for Discharge of Sewage into Urban Sewers", the initial rainwater (that is, within 15 minutes) connected to the municipal pipe network must meet its standards. Garbage such as garbage, leaves, cigarette butts, etc., will enter the storm water outlet during the cleaning process of sanitation workers. In addition, some citizens use the rain water outlet as a dumping port for domestic sewage and garbage, which makes the rain water outlets of most cities in our country collect a large amount of unnecessary garbage. Garbage clogs the gutter, which is not co...

Problems solved by technology

[0004] The invention aims to solve the problem that a large amount of rubbish easily enters the traditional gully, and when it rains, too much garbage in the gully cannot dredge the rainwater, or even block the problem. Even if the rainwater can be dredged, a large amount of soil, cigarette butts, paper scraps, leaves etc. into the sewage treatment plant, greatly increasing the sewage treatment load, especially the surge in COD and SS values

This device can solve the problem that a large amount of garbage easily enters the rainwater outlet and damages the water environment system. It has the function of opening the orifice to collect rainwater in rainy days
