Urban management work includes industry and commerce, transportation, public security, culture and education, environment, sanitation and infrastructure, etc. Drainage manhole cover is a kind of municipal administration. Municipal drainage manhole cover is a kind of drainage and maintenance equipment widely installed on municipal roads. Usually municipal manhole covers are composed of a manhole cover body and drainage holes that pass through the manhole cover body.

[0003] Most of the existing manhole covers can support normal drainage work, but when there is a lot of garbage or trees, after the manhole cover has been used for a long time, leaves or garbage will be blocked on the sewer manhole cover, causing water accumulation or poor drainage on the road, which not only reduces the use effect, but also easily causes a certain impact on municipal roads.

[0008] Preferably, an arc rod is fixedly installed at the bottom of the sliding rod, a rotating shaft is rotatably installed at the bottom of the manhole cover body, an impeller is fixedly installed on the outer wall of the rotating shaft, which can drive the rotating shaft to rotate and the cam to rotate, and a movable groove begins to be formed on the outer wall of the rotating shaft.

[0009] Preferably, a cam is slidably connected inside the movable groove, which can enable the arc rod to drive the slide rod to move in the square groove of the support plate. A movable spring is fixedly installed at the bottom of the cam to reset the slide rod. The end of the movable spring away from the cam is fixedly installed at the bottom of the movable groove.

[0010] Preferably, the bottom of the support plate fits on the top of the cam, so that the support plate can be lowered and the cam can be driven to move downward in the moving groove.

[0011] Preferably, the cleaning mechanisms are distributed in a circular array around the center of the manhole cover body, which can make the top of the manhole cover body clearer.

[0012] Compared with the prior art, the utility model provides a manhole cover drainage structure that can prevent clogging, and has the following beneficial effects:

[0013] 1. The anti-clogging manhole cover drainage structure, when it rains, rainwater will flow into the bottom of the manhole cover, but the water flow will also bring garbage to the top of the manhole cover, causing the manhole cover to be blocked. The flow of rainwater drives the impeller to rotate on the rotating shaft, which can make the cam rotate, and squeeze the arc rod during rotation, so that the arc rod drives the cleaning rod on the sliding rod to move, so that the cylinder above the cleaning rod can clean the top of the manhole cover back and forth to prevent the manhole cover from being blocked.

[0014] 2. The anti-clogging manhole cover drainage structure may have vehicles passing over the top of the manhole cover. Through the squeezing of the vehicle, the wheels and other objects can squeeze the cylinder, so that the slide rod drives the support plate to descend, and the ring will also descend at this time, driving the tension spring to stretch, and the support plate will squeeze the cam to compress the moving spring. After the wheel passes, the cam and the ring will be reset, allowing the cylinder to move up and down, which can better clean up the garbage above the manhole cover without hindering traffic.

DETAILED DESCRIPTION

[0020] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a manhole cover drainage structure that can prevent clogging, including a manhole cover body 1, the bottom of the manhole cover body 1 is fitted with a limit plate 2 to prevent the manhole cover body 1 from falling into the sewer, and the bottom of the manhole cover body 1 is provided with a cleaning mechanism 3, which can dredge the top of the manhole cover body 1, and the cleaning mechanism 3 is distributed in a circular array with the center of the manhole cover body 1, which can make the top of the manhole cover body 1 dredge more smoothly.

[0021] Specifically, the cleaning mechanism 3 includes: a tension spring 31, a ring 32, a support plate 33, a slide rod 34, a reset spring 35, a cleaning rod 36, a cylinder 37, an arc rod 38, a rotating shaft 39, an impeller 310, a moving groove 311, a cam 312, and a moving spring 313. The bottom of the limit plate 2 is fixedly installed with a tension spring 31, which can reset the ring 32 when stretched. The end of the tension spring 31 away from the limit plate 2 is fixedly installed with a ring 32, which can facilitate the installation of the support plate 33. A support plate 33 is fixedly installed at the bottom of 32 to facilitate the sliding of the slide bar 34. The slide bar 34 is slidably connected to the square groove of the support plate 33 to drive the cleaning rod 36 to move. A return spring 35 is fixedly installed on the top of the slide bar 34 to reset the slide bar 34 when it is squeezed. The end of the return spring 35 away from the slide bar 34 is fixedly installed on the top of the square groove of the support plate 33 for fixing. A cleaning rod 36 is fixedly installed on the left side of the slide bar 34 to facilitate the installation of the cylinder 37. The right side of the cleaning rod 36 is fixed A cylinder 37 is installed to clear the garbage above the manhole cover body 1. An arc rod 38 is fixedly installed at the bottom of the slide bar 34 to drive the slide bar 34 to move in the square groove of the support plate 33. A rotating shaft 39 is rotatably installed at the bottom of the manhole cover body 1 to facilitate the installation of an impeller 310. An impeller 310 is fixedly installed on the outer wall of the rotating shaft 39 to rotate the rotating shaft 39 through water flow. A moving groove 311 is formed on the outer wall of the rotating shaft 39 to facilitate the cam 312 to be squeezed by the support plate 33. 2 moves downward, a cam 312 is slidably connected inside the moving groove 311, which can move the arc rod 38, and the bottom of the support plate 33 fits on the top of the cam 312, so that the support plate 33 can be lowered and drive the cam 312 to move downward in the moving groove 311, and a moving spring 313 is fixedly installed at the bottom of the cam 312 to reset the cam 312, and one end of the moving spring 313 away from the cam 312 is fixedly installed at the bottom of the moving groove 311 for fixing the moving spring 313.

[0022] Working principle: when it rains, rainwater will flow into the bottom of the manhole cover body 1, but the water flow will also bring garbage to the top of the manhole cover body 1, causing the manhole cover body 1 to be blocked. The flow of rainwater drives the impeller 310 to drive the rotating shaft 39 to rotate, so that the rotating shaft 39 can drive the cam 312 to rotate, and when the cam 312 rotates, it squeezes the arc rod 38, so that the arc rod 38 drives the sliding rod 34 to move and the return spring 35 is squeezed. While the sliding rod 34 moves, it drives the cleaning rod 36 to move, so that the cylinder 37 on the cleaning rod 36 moves back and forth, so that the cylinder 37 above the cleaning rod 36 can clean the top of the manhole cover body 1 back and forth, so as to prevent the manhole cover body 1 from being blocked and causing problems such as water accumulation on the road.

[0023] A vehicle may pass over the top of the manhole cover body 1. Through the squeezing of the vehicle, the wheels and other objects can squeeze the cylinder 37, so that the cleaning rod 36 drives the sliding rod 34 to descend, and the sliding rod 34 drives the supporting plate 33 to descend. The ring 32 will also descend at this time, driving the tension spring 31 to stretch, and the supporting plate 33 will squeeze the cam 312 to make the cam 312 move downward in the moving groove 311, and the moving spring 313 is compressed. After the wheel passes, the moving spring 313 will drive the cam 312 to reset, and the tension spring 31 will drive the ring 32 to reset, so that the cylinder 37 can move up and down, which can better clean the garbage above the manhole cover body 1, and can prevent the manhole cover from being blocked without hindering traffic.

[0024] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
