Non-power automatic overturning type anti-blockage rain opening

Abstract

The invention discloses a non-power automatic overturning type anti-blockage rain opening mainly comprising a rain opening body and a rain opening cover; the upper part of the rain opening cover is rotatably fixed on the rain opening body through a rotating rod; a floating ball bin inflow pipe and a floating ball bin are arranged on the lower part of the rain opening body, a floating ball is arranged in the floating ball bin, and at least one connecting rope connects the floating ball with the rain opening cover through a plurality of pulleys; and a bottom weep hole is also formed on the lower part of the rain opening body. The non-power automatic overturning type anti-blockage rain opening disclosed by the invention is provided with the movable rain opening cover and is equipped with the floating ball and the connecting rope, so that when rubbish blocks the rain opening, the floating ball provides power to automatically overturn the rain opening cover, so that rubbish is flushed into a pollutant intercepting cradle with the rain, the water intake capability of the rain opening is recovered, and the technical aims of quickly transmitting the rain on the road and reducing the ground seeper during rainstorm process are achieved; and the non-power automatic overturning type anti-blockage rain opening has the beneficial effects of simple structure and convenience in realization, etc.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage, in particular to an anti-blocking rainwater outlet with no power and automatic flipping. Background technique [0002] The stormwater outlet is an important part of the urban drainage system. It is not only the bottleneck of urban pipelines collecting rainwater runoff, but also the primary channel for urban non-point source pollutants to enter the water environment. Therefore, the stormwater outlet occupies an important position in the urban drainage system. [0003] The rainwater outlet, also known as the rainwater collection well, is a facility for the pipeline drainage system to collect surface water. It is generally composed of water inlet grates, well bodies, and water collection branch pipes. The rain outlet discharges rainwater into the main pipe through the water collection branch pipe. It is an auxiliary structure of the urban drainage system and an important part of ur...

AI Technical Summary

Problems solved by technology

[0004] 1. The accumulated water will form splashes under the action of driving, which will affect the sight of subsequent vehicles

[0005] 2. Asphalt mixture soaked in water for a long time is easy to peel off and reduce the strength of road surface

[0006] 3. When the water accumulates to a certain thickness, it will form "water floating" when driving, causing the wheels to slip

[0007] 4. During heavy rain, it is very easy to cause a large area of ​​water to form on the road surface, resulting in traffic paralysis and great economic losses

[0008] However, at present, the old urban areas of most cities still use the traditional single vertical grate water intake or flat grate water intake. Due to the influence of the terrain and the blockage of garbage and debris, the water flow area of ​​the orifice of the rainwater outlet of many roads is relatively small, and the water is collected when it rains. Slower, less drainage capacity, single type, and serious blockage and damage

Once the drainage capacity of the rainwater outlet is insufficient, even if the design capacity of the pipeline is high, it will cause water accumulation on the road surface, which will not be able to play the role of the design capacity of the pipeline
