Drainage device with flood discharge function for municipal field

Abstract

The invention relates to the technical field of drainage, and discloses a drainage device with a flood discharge function for the municipal field. The drainage device comprises a foundation, and a flood discharge box is fixedly installed at the top of the foundation. According to the drainage device with the flood discharge function for the municipal field, a water inlet pipe is connected with a sewer; when raining, rainwater reaches the interior of the flood discharge box along the water inlet pipe and reaches the interior of a drainage pipe through a filter screen for drainage; when raining heavily, more rainwater is accumulated in the flood discharge box; when the rainwater overflows a water level alarm, an alarm is given, at the moment, a driving motor starts to run; and when an output shaft of the driving motor rotates, a connecting sleeve, a rod and a push piece are driven to rotate, the rotated push piece makes contact with the rainwater, thrust is provided for the rainwater, the circulating speed of the rainwater is higher, therefore, drainage is faster, the flood discharge effect is improved, water is pressurized through cooperation of an additional pump, and the purpose of high drainage speed is achieved.

Description

technical field [0001] The invention relates to the technical field of drainage, in particular to a drainage device with flood discharge function used in the municipal field. Background technique [0002] The urban drainage system is an engineering facility system for treating and removing urban sewage and rainwater. It is an integral part of urban public facilities and is mainly formed by connecting drainage pipes extending in all directions. However, for urban low-lying areas, once a large amount of rainfall occurs Therefore, it is necessary to strengthen the drainage effect of the drainage pipes. [0003] For example, Chinese patent CN 107060053 B discloses a drainage structure for municipal roads. The drainage structure includes a drainage well arranged between motor vehicle lanes and non-motor vehicle lanes. A grid assembly is installed at the wellhead of the drainage well. The grid The assembly is cylindrical, and the grid assembly is lying on the wellhead of the drai...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a drainage device with a flood discharge function for municipal use, which has the advantages of fast drainage speed and solves the shortcoming of slow drainage speed. In the case of a large amount of rainfall, the drainage The drainage speed of the structure is slow, which makes the entire drainage system very easy to collapse, which further leads to waterlogging and affects people's travel problems
