Problems solved by technology

In order to solve the above problems, some anti-theft manhole covers have also appeared in recent years, but most of them have poor anti-theft effects, or have complex structures, or are not easy to open.
[0003] At present, the common method is to add a lock on the manhole cover. The advantage is that the lock is not easy to be damaged, and it can play a role in preventing theft to a certain extent. The disadvantage is that the exposed lock may affect the movement of people and vehicles. After the manhole cover is rusted, it will be scrapped quickly. The safekeeping of the manhole cover is another problem. Careless confusion or loss will also lead to the abandonment of the manhole cover.
The structure of the traditional anti-theft manhole cover is generally more complicated, and when detecting whether the manhole cover is moved or stolen, it is impossible to get an accurate judgment result, which brings trouble to the anti-theft work of the manhole cover

Abstract

The invention discloses a well lid monitoring and warning system and method. The well lid monitoring and warning system comprises a well lid body. A drive piece and a control box are arranged on the lower surface of the well lid body. A mercury switch device is arranged on the drive piece. A positive and negative electrode contact jaw and a mercury movable ball are arranged inside the mercury switch device, wherein the mercury movable ball can move inside the mercury switch device and can make electric contact with the positive and negative electrode contact jaw or can be electrically separated from the positive and negative electrode contact jaw, and the positive and negative electrode contact jaw is electrically connected with the control box through a wire; one end portion of the drive piece is hinged to the lower surface of the well lid body, and the other end portion of the drive piece is flush with the edge of the outer circle of the well lid body. The well lid monitoring and warning system is novel in structure, ingenious in design and high in detection feedback speed, and the well lid anti-theft effect can be simply, conveniently and rapidly achieved. The drive piece with the mercury switch device is arranged on a well lid. When the well lid moves, the mercury switch device will immediately change from a turned-on state to a turned-off state, and the control box can detect state change information and transmits the state change information to a monitoring center or warning equipment.

Description

technical field [0001] The invention relates to a well cover monitoring and alarming device and a method thereof, in particular to a well cover monitoring and alarming system and a method thereof. Background technique [0002] In municipal construction, due to the need to bury and maintain underground pipelines in the future, it is necessary to set up sewage pipeline wells, gas pipeline wells, and power and communication cable operation wells under the road surface. Various wells provide us with water power continuously. Electricity, communication and other aspects of services. Due to its poor anti-theft effect, in the cities we live in, there are always some criminals who frantically steal manhole covers and sell them at the cost of sacrificing the public interest. We can always see "big pits" with a diameter of one meter, which undoubtedly planted "landmines" for the safety of public facilities, traffic and pedestrians, seriously endangering the lives and property of pass...
