Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent well covers, more particularly to an intelligent well cover and a monitoring management system thereof. BACKGROUND

[0002] A well cover is an object used to cover the well mouth of a deep well in a road or a house, mainly functions to prevent people or objects from falling and to ensure the safety of pedestrians and vehicles. As an important part of the urban underground pipeline system, the well cover is covered on various well mouths such as drainage wells, cable wells, gas wells, etc. During the rainy season or heavy rain, it can also help to quickly drain surface water to prevent urban waterlogging, and provides a direct access to underground facilities for workers, facilitating daily maintenance, repair and emergency treatment. According to the material, the well cover can be divided into metal well cover, high-strength fiber cement concrete well cover, resin well cover and polymer-based composite well cover, etc. According to the shape, the well cover can be divided into round well cover and square well cover.

[0003] At present, as a key component of urban infrastructure, the well cover is widely distributed in streets, communities, factory areas, parks and other areas, covering various underground such as sewers, communication cable wells, power inspection wells, etc. The structure is mainly a flat type with a round or square shape, which is placed by embedding into a well seat, and is connected and fixed with the well seat by relying on the self-weight of the well cover or a simple hinge device cooperating with a limiting slot, so as to prevent the well cover from being accidentally displaced or lost. For the drainage well cover laid on both sides of the forest road, due to the existence of many trees on both sides of the forest road, a large amount of dry branches and fallen leaves are easily scattered on the surface of the forest road under the action of wind and in a specific season. Therefore, the surface of the traditional well cover is easily covered by dry branches and fallen leaves. When encountering heavy rain, the contact of rainwater and fallen leaves will increase the adhesion of fallen leaves to the well cover, causing the fallen leaves to adhere to the surface of the well cover, resulting in well cover congestion and causing waterlogging. Generally, manual opening of the well cover is required to manually open the well cover for dredging, which is very inconvenient. In view of this, the present application provides an intelligent well cover and a monitoring management system thereof. SUMMARY
