Problems solved by technology

[0003] However, when existing manhole covers are in use, due to the presence of a large amount of soil on the road, the soil will enter the manhole cover along with the water flow, and will adhere to the manhole cover in the form of silt, which will easily cause the blockage of the manhole cover, thus making the manhole cover The drainage function of the road is reduced, so that the water on the road cannot be discharged in time, resulting in serious water on the road and affecting the traffic in the city. Therefore, it is necessary to design a self-cleaning system for the filter screen of the green urban manhole cover to solve the above problems

Embodiment 1

[0025] refer to Figure 1-3 , a self-cleaning system for a green city manhole cover filter screen, comprising a cover body 1, a plurality of water inlets 2 are provided on the upper side wall of the cover body 1, a drainage groove 3 is provided on the lower side wall of the cover body 1, and a plurality of water inlet channels 2 are provided. It communicates with the drainage tank 3, and the inner wall of the drainage tank 3 is fixedly connected with a filter screen 4.

[0026] The cover body 1 is provided with a cleaning mechanism for cleaning the filter screen 4. The cleaning mechanism includes two communication grooves 7 arranged on the top of the drain tank 3. The cross sections of the two communication grooves 7 are both inverted J-shaped structures. The inner wall of the groove 7 is fixedly connected with a sand-based permeable plate 17, which can prevent dust from passing through the connecting groove 7, but has good water permeability. A control chamber 13 is provided ...

Embodiment 2

[0031] refer to Figure 4 , a self-cleaning system for the filter screen of a green city manhole cover, the inner wall of the installation cavity 8 is fixedly connected with the installation bar, the side wall of the installation bar is fixedly connected with the tuning fork 21, the tuning fork 21 is arranged horizontally, the upper side wall of the tuning fork 21 is attached to the top of the installation cavity 8 Close, the lower side wall of the tuning fork 21 is attached to the upper side wall of the dividing plate 9 .

[0032] In this embodiment, when a vehicle passes by, the roar of the automobile engine causes the tuning fork 21 to resonate, and the tuning fork 21 rubs against the installation cavity 8 and the partition 9 continuously, which can increase the temperature of the installation cavity 8 and the partition 9, thereby making the installation The temperature of the air in the cavity 8 increases gradually. Since the higher the temperature, the greater the air pre...

Abstract

The invention discloses a green city inspection well cover filter screen self-cleaning system which comprises a cover body, a plurality of water inlet channels are formed in the upper side wall of thecover body, a drainage groove is formed in the lower side wall of the cover body, and a filter screen is fixedly connected to the inner wall of the drainage groove; a cleaning mechanism used for cleaning the filter screen is arranged in the cover body and comprises two communicating grooves formed in the inner top of the drainage groove, a control cavity is formed in the cover body, a placing plate is slidably connected to the inner wall of the control cavity, an air bag is fixedly connected to the inner bottom of the control cavity, and an air suction pipe is arranged on the side wall of theair bag in a communicating mode; a water swelling water stop block is fixedly connected to the upper side wall of the placing plate, a mounting cavity is formed in the cover body, the mounting cavityis communicated with the air bag through an air guide pipe, and a partition plate is fixedly connected to the inner wall of the mounting cavity. Sludge attached to the filter screen can be automatically brushed away, the drainage performance of the inspection well cover is guaranteed, and then normal circulation of urban traffic is guaranteed.

Description

technical field [0001] The invention relates to the technical field of urban construction equipment, in particular to a self-cleaning system for a filter screen of a green urban manhole cover. Background technique [0002] The manhole cover is a kind of drainage equipment for urban roads. Usually, when it is installed, the manhole cover is slightly lower than the road surface, so that the water on the road surface can be collected on the manhole cover, and then discharged through the manhole cover, which can prevent serious damage to the road surface in heavy rainfall weather. The accumulated water ensures the normal flow of urban traffic. [0003] However, when existing manhole covers are in use, due to the presence of a large amount of soil on the road, the soil will enter the manhole cover along with the water flow, and will adhere to the manhole cover in the form of silt, which will easily cause the blockage of the manhole cover, thus making the manhole cover The draina...
