Municipal road rainwater automatic drainage device

Abstract

The invention discloses a municipal road rainwater automatic drainage device which comprises a tank body, a lifting mechanism fixed on the side wall of the tank body, and an inner water tank fixed bythe lower end of the lifting mechanism and controlling water storage and weight increasing by flow in the tank body. The bottom of the inner water tank is provided with a flow control valve, the upperportion of the tank body is provided with a cover plate which is fixed with the upper end of the lifting mechanism and is used for covering the tank body, the lifting mechanism is a six-link mechanism composed of six mutually-connected connecting rods, an upper shaft of the six-link mechanism is connected with the cover plate, a lower shaft of the six-link mechanism is connected with the inner water tank, a middle shaft of the six-link mechanism is fixed to the side wall of the tank body, and the lower portion of the tank body is provided with a water discharging port the same as a municipaldischarging port. The municipal discharge cover plate is automatically lifted when the rainfall is large by utilizing the water flow speed control and water storage weight, the cover plate is automatically closed when it stops raining, and plenty of work of manually opening the cover plate during rainstorm early warning each time to increase the water flow speed and returning the cover plate againwhen the rainstorm is over can be omitted.

Description

technical field [0001] The invention relates to the technical field of drainage, in particular to an automatic rainwater drainage device for municipal roads. Background technique [0002] In the construction of municipal roads, rainwater drainage is essential. When there is a heavy rain, the existing drainage device often produces road water accumulation due to the limited flow rate of the manhole cover hole, which poses hidden dangers to road traffic. Now road managers can only manually open the drainage manhole covers before the rainstorm according to the weather forecast to increase the water flow rate and avoid water accumulation on the roads. There are a huge number of manhole covers that need to be opened in cities. Based on the problems referred to above, the currently known method of manually opening the manhole cover solves the problem. [0003] However, it is time-consuming and labor-intensive to manually solve the above-mentioned problems. After the manual openin...

Problems solved by technology

[0003] However, the above-mentioned manual solution to the above-mentioned problems is time-consuming and labor-intensive. After the manual opening, it needs to be covered manually after the rainstorm ends. In municipal roads, a device that can automatically open and close the drainage manhole cover according to the amount of rainfall is needed to solve the problem.
