Problems solved by technology

[0002] Most of the manhole covers used today are cast iron manhole covers. This kind of manhole cover has no alarm and anti-theft function, so it is easy to be stolen and the manhole cover cannot be tracked
In addition, the anti-drop performance of traditional well covers is also poor. Generally, nylon nets are used to hang on the hooks on the inner wall of the well. Because nylon nets are easy to corrode, the bearing capacity is poor, and because the quality of nylon nets is easily washed away by water, the anti-fall function is lost. ,There are security risks

Abstract

The invention discloses a multi-function manhole cover. The multi-function manhole cover comprises a pressure sensor which is arranged on a manhole cover and a mechanical transmission device. The mechanical transmission device comprises a pushing rod, a roller which is connected with the rear end of the pushing rod and a cam which contacts with the roller to push the pushing rod to move forward and backward. The pressure sensor is arranged in front of the pushing rod and contacts with the front end of the pushing rod. The pressure sensor is connected with an alarm concentrator which is connected with a client side. When opened illegally, the manhole cover has an alarm function.

Description

technical field [0001] The invention relates to a multifunctional well cover. Background technique [0002] Most of the manhole covers used today are cast iron manhole covers. This type of manhole cover has no alarm and anti-theft functions, so it is easy to be stolen and cannot be tracked. In addition, the anti-drop performance of traditional well covers is also poor. Generally, nylon nets are used to hang on the hooks on the inner wall of the well. Because nylon nets are easy to corrode, the bearing capacity is poor, and because the quality of nylon nets is easily washed away by water, the anti-fall function is lost. ,There are security risks. Contents of the invention [0003] The invention provides a multifunctional manhole cover, which has an alarm function when the manhole cover is opened illegally. [0004] In order to solve the above problems, the technical solution adopted by the present invention is as follows: a multifunctional manhole cover includes a pressur...
