Description

Technical Field

[0001] The present invention relates to the technical field of intelligent manhole covers, and in particular to an intelligent manhole cover with environmental self-adaptation function. Background Art

[0002] Manhole covers are used to cover deep wells on roads or in homes to prevent people or objects from falling. According to the material, they can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc., generally in round and square shapes. They can be used in green belts, sidewalks, motorway lanes, docks, alleys, etc. With the continuous development of urbanization, more and more manhole covers are appearing in cities, but the existing manhole cover structure is relatively simple and can only achieve the function of covering the wellhead. Manhole covers are usually provided with drainage holes, but when heavy rain occurs, the drainage holes are easily flooded, resulting in poor drainage and serious waterlogging on the road. Workers are required to manually open the manhole covers to improve the drainage effect. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the above technical difficulties and provide an intelligent manhole cover with environmental adaptive adjustment, which can adjust the drainage effect according to the rainfall and prevent water accumulation on the road.

[0008] As an improvement, a limiting strip is fixedly connected to one side of the manhole cover, and a limiting slot cooperating with the limiting strip is provided on the inner wall of the adjustment frame.

[0009] The advantages of the present invention compared with the prior art are:

[0010] (1) The water baffle can be driven to slide forward and backward along the regulating cavity through the regulating mechanism, so that the first drainage hole and the second drainage hole are arranged alternately, thereby adjusting the size of the drainage hole. In conjunction with the rain sensor, the drainage hole can be adaptively adjusted according to the annular needs.

[0011] (2) When the rainfall is heavy, the rotating mechanism is started to drive the adjusting ring to rotate, and the adjusting ring drives the supporting column to rotate, so that the supporting column slides along the inclined surface of the supporting block, and the manhole cover is lifted upward, so that the rainwater is directly discharged into the well through the installation frame. There is no need for the staff to manually open the manhole cover to drain water, and at the same time, the manhole cover is prevented from being fully opened, causing the risk of pedestrians falling.
