Anti-blocking well lid for sponge city

Abstract

The invention discloses an anti-blocking well lid for a sponge city. The anti-blocking well lid comprises a well body, wherein a well lid body is welded and fixed to the well body, a water guide opening is formed in the well lid body and penetrates through the well lid body, a straight rod is slidably connected to the center of the well lid body and penetrates through the well lid body, a metal plate is welded and fixed to the end, located above the well lid body, of the straight rod and abuts against the surface of the well lid body, a piezoelectric medium is arranged in the metal plate, a battery is arranged in the well lid body, and the piezoelectric medium communicates with the battery through a wire. The anti-blocking well lid has the advantages that when the water guide opening is blocked, the water level rises, thus water enters a box through a water inlet pipe, the straight rod rises, a trigger switch is started, a water pump is started, garbage is washed away, and the water drainage efficiency is ensured; and by utilizing the characteristic that the environment temperature is too high in summer, a liquid bag expands, thus the straight rod rises, water flow is sprayed out from a water drainage pipe, and thus the pavement is cooled.

Description

technical field [0001] The invention relates to the technical field of sponge cities, in particular to an anti-clogging manhole cover for sponge cities. Background technique [0002] Sponge city refers to the fact that the city, like a sponge, has good resilience in adapting to environmental changes and dealing with natural disasters caused by rain. Substantial application of "sponge city" materials, showing excellent water seepage, compression resistance, wear resistance, non-slip, environmental protection, beautiful and colorful, comfortable and easy to maintain, sound absorption and noise reduction, etc., has become a "breathing" urban landscape pavement, and is also effective Alleviate the urban heat island effect, so that the urban pavement is no longer hot. [0003] Manhole covers, especially those in municipal engineering, generally appear in places such as roads or parks, and are used to cover wells to prevent people or objects from falling. Yet the well cover on t...

Problems solved by technology

However, during normal use, the drainage holes on the manhole cover are often blocked by garbage. If the drainage hole of the manhole cover is blocked, it will not be able to drain water in time when it rains, and urban waterlogging will occur, which requires manual cleaning. It can drain normally, which is a great waste of manpower and material resources, and it cannot be cleaned in time, which will affect people's travel
