Rainwater lifting and draining device for urban roads

Abstract

The invention discloses a rainwater lifting and draining device for urban roads. The rainwater lifting and draining device comprises an idler wheel, a water inlet mechanism, a first water draining pipe, a base, a water inlet pipe, a limiting plate, a spring, a first baffle, a limiting column, second baffles, a water storage tank, a water inlet barrel, a piston, a screw rod, a rotating wheel, a handle, a hose, a second water draining pipe, a water valve and scale lines. According to the rainwater lifting and draining device for the urban roads, the water storage tank is internally provided withthe sealed water inlet barrel, the piston is slidably arranged in the water inlet barrel, the water storage tank is connected with the rotating wheel screw rod, the rotating wheel rotates, then the screw rod can drive the piston to go up, the air pressure inside the water inlet barrel is reduced, the two second baffles move upwards, the water inlet pipe is opened, the first water draining pipe isclosed, under action of the air pressure, accumulated water enters the interior of a water inlet tank from the water inlet pipe, and the road accumulated water is removed quickly; and when the waterinlet barrel is full, the rotating wheel rotates to make the screw rod drive the piston to go down, the water in the water inlet barrel is squeezed, the two second baffles go down, the water inlet pipe is closed, the first water draining pipe is opened, then water can be squeezed from the water inlet tank to the interior of the water storage tank, and backflow of the accumulated water is prevented.

Description

technical field [0001] The invention relates to a rainwater lifting and discharging device, in particular to an urban road rainwater lifting and discharging device, and belongs to the technical field of rainwater treatment applications. Background technique [0002] Rain refers to the weather phenomenon in which water vapor condensed in the atmosphere falls to the earth's surface in various ways. Almost all the water vapor in the atmosphere is concentrated in the troposphere. The higher the temperature, the more water vapor the atmosphere can hold, and vice versa. At a certain temperature, when the air cannot hold more water vapor, it is called saturated air. When the water vapor in the saturated air matches the temperature, condensation does not occur, but when the air is supersaturated, excess water vapor is produced and condensation occurs. [0003] When it rains, a lot of rainwater falls on the road. The flatness of the road is different. A lot of rainwater accumulates...

AI Technical Summary

Problems solved by technology

[0003] When it rains, a lot of rainwater falls on the road. The flatness of the road is different. A lot of rainwater accumulates in the low-lying places of the road. The degree of danger of people driving vehicles is not conducive to people's safety, and a large amount of rainwater accumulates together, and the rainwater is difficult to evaporate, which is not conducive to people walking on the road
