Rainwater grate device

Abstract

The rainwater grate device comprises a bearing plate, a grate plate and a descending part, a water opening matched with the grate plate is formed in the middle of the bearing plate, the descending part comprises a locking part and a guide part, the guide part comprises a bottom ring and a guide column, the upper end of the guide column is fixedly connected to the bottom of the bearing plate, and the lower end of the guide column is fixedly connected to the bottom of the bearing plate. The bottom ring is fixedly connected to the lower ends of the guide columns; the grid plate is arranged on the guide columns in a sliding mode, the locking part comprises a check block, the check block is arranged at the bottom of the bearing plate in a sliding mode, the grid plate is embedded in the water gap, and the check block is moved to be arranged at the bottom of the grid plate in a blocking mode; the device can be installed on a drainage system on a road and used for coping with the situation of large water flow, when rainstorm or extra-heavy rainstorm occurs, the water port in the grid plate cannot quickly drain water flow into a water channel, at the moment, the check block can be moved, the grid plate is opened, the grid plate falls onto the bottom ring at the lower end along the guide column, and the water flow can quickly flow into the water channel from the water port; disasters caused by a large amount of accumulated water due to the fact that water flow cannot be drained are avoided.

Description

technical field [0001] The invention relates to the field of rainwater dredging devices, in particular to a rainwater grate device. Background technique [0002] In the rainwater drainage of general construction sites or municipal roads, when encountering heavy rain or heavy rain, it usually occurs that the rainwater is difficult to discharge and the rainwater grate is blocked, resulting in a large amount of water accumulation, causing inconvenience to the daily life of personnel, and may even It will cause huge loss of life and property. The traditional rainwater grate has a simple structure, and it is easy to block the drainage hole with daily garbage or construction waste. When the rainwater flow is large, it is more likely to cause blockage, resulting in difficult drainage; and the ordinary rainwater grate drains through the drainage hole. When there is water on the road, the immediate drainage capacity is limited, which will cause a large amount of accumulated water th...
