[0002] The manhole cover is a facility used to block the sewer on the road surface. The surface of the manhole cover is usually equipped with a small-diameter drain, which can meet the drainage demand of small rainfall, but when the rainfall is large, the drain is far from meeting the drainage demand. The current treatment method is to completely lift the manhole cover and place it next to the sewer. This method leads to the direct exposure of the sewer. Although the drainage volume is greatly increased, it is neglected in management and affects normal driving. Pedestrians may fall will happen,

Embodiment
[0019] refer to Figure 1-4 , a municipal road manhole cover, comprising an inner cover plate 1 and an outer ring plate 2 distributed inside and outside and arranged coaxially, the inner cover plate 1 is composed of a circular plate 3 in the center and a plurality of fixed sectors integrally formed on the outer peripheral surface of the circular plate 3 The fixed sector plate 4 is fixedly connected with the outer ring plate 2, and the circular plate 3 and multiple fixed sector plates 4 jointly form a plurality of fan-shaped drainage outlets 5 evenly distributed around the circumference. The inner wall of the circular plate 3 is embedded with a motor 8 , it should be noted that the motor 8 is a deceleration stepping motor, and the step angle of the motor 8 is the angle occupied by a single fixed sector plate 4 or the moving sector plate 6, and the step angle can be set by a matching step driver , the output end of the motor 8 runs through the circular plate 3 and is fixedly con...

The invention discloses a municipal road well lid. The municipal road well lid comprises an inner cover plate and an outer ring plate which are distributed inside and outside and are coaxially arranged, wherein the inner cover plate is composed of a circular plate located in the center and a plurality of fixed fan-shaped plates integrally formed on the outer circumferential surface of the circularplate, and the fixed fan-shaped plates are fixedly connected with the outer ring plate. The municipal road well lid has the advantages that when the rainfall is large, a fixed drainage port and a movable drainage port cannot meet the drainage requirement, a motor drives a rotating column to rotate along a third sliding groove, due to the fact that inclined surfaces which are matched with each other are arranged between the movable fan-shaped plates and the fixed fan-shaped plates, a downward component force is generated on the movable fan-shaped plates, the plurality of movable fan-shaped plates gradually move downwards in the rotating process until the movable fan-shaped plates rotate to the position below the fixed fan-shaped plates adjacent to the movable fan-shaped plates, so that thefan-shaped drainage ports are completely exposed and are not shielded so as to adapt to drainage with large rainfall, the well lid does not need to be opened, the plurality of fixed fan-shaped platesare high in bearing capacity, vehicles and pedestrians are prevented from falling into the well lid, and the safety is improved.
Description
technical field [0001] The invention relates to the technical field of manhole covers, in particular to a municipal road manhole cover. Background technique [0002] The manhole cover is a facility used to block the sewer on the road surface. The surface of the manhole cover is usually equipped with a small-diameter drain, which can meet the drainage demand of small rainfall, but when the rainfall is large, the drain is far from meeting the drainage demand. The current treatment method is to completely lift the manhole cover and place it next to the sewer. This method leads to the direct exposure of the sewer. Although the drainage volume is greatly increased, it is neglected in management and affects normal driving. Pedestrians may fall will happen, [0003] In order to solve the above problems, we propose a municipal road manhole cover. Contents of the invention [0004] The purpose of the invention is in order to solve the problem in the background technology, and a k...
