[0003] The conventional municipal drainage inspection anti-falling device does not have the functions of automatically opening during heavy rain and blocking branches, leaves and other household garbage during drainage, and the garbage flowing into the well causes accumulation in the well and leads to poor drainage. Some drainage devices need to be manually opened to drain water when it rains, and the signs may be washed away by rain, which may cause pedestrians to fall or damage cars. To solve the above problems, a municipal engineering drainage inspection well anti-falling device is proposed. UTILITY MODEL CONTENTS

[0006] Preferably, a water storage barrel is arranged inside the well body, two symmetrically arranged fixed blocks are fixedly connected to the surface of the water storage barrel, and two symmetrically arranged water discharge grooves are formed in the inner bottom surface of the water storage barrel.
[0007] Preferably, a tension spring rod is rotatably connected to the inner wall of each tension spring shell, a tension spring is fixedly connected to the surface of the tension spring rod, the end of the tension spring away from the tension spring rod is fixedly connected to the inner wall of the tension spring shell, one end of the tension spring rod penetrates through the inner wall of the tension spring shell and extends to the outside, and the one end of the tension spring rod is fixedly connected to one end of the rotating shaft.
[0008] Preferably, one end of the pull rope is fixedly connected with the surface of the rotating shaft, the other end of the pull rope is fixedly connected with the surface of the fixed block, the pull rope is located between the two gears, and the pull rope is clockwise wound.
[0009] Preferably, the upper portion of the well body is provided with a well cover, a plurality of annularly arranged drainage grooves are formed in the surface of the well cover, and the height of the well cover is the same as the height of the circular grooves.

[0011] The utility model discloses an improved municipal engineering drainage inspection well anti-falling device, which has the following improvements and advantages compared with the prior art.
[0012] Firstly, the utility model discloses two symmetrical water release grooves and drainage grooves, which realize the anti-falling and drainage of the inspection well. When the rainfall is small, the rainwater can be drained through the water release grooves without driving the well cover to rise. When it is raining heavily, the speed of the water release grooves cannot keep up with the drainage, resulting in too much rainwater in the water storage barrel. At this time, the water storage barrel drives the pull rope on the rotating rod to rotate, and the gear strip is driven to rise, so that the well cover is displaced upward, allowing more rainwater to quickly flow into the drainage well. When the rainfall decreases, the rainwater in the water storage barrel decreases, and the well cover is reset.
[0013] Secondly, the utility model can prevent branches or other garbage from falling into the well due to the loss or damage of the well cover. During heavy rain, a lot of garbage or branches will enter the inspection well with the rainwater. At this time, the drainage grooves on the well cover can prevent the branches and garbage from entering the drainage well while allowing the rainwater to flow into the well, thereby avoiding the blockage caused by the branches entering the drainage well.
