Well lid linkage system

Abstract

The invention provides a well lid linkage system. The system comprises a power supply module, a master control unit and an electromagnetic lock well lid, wherein the electromagnetic lock well lid comprises a well lid, a well ring, a lock body, an activating key and an emergency key; the activating key is inserted into the keyhole of the lock body before unlocking to trigger a wake-up switch and activate the master control unit; the master control unit is connected to APP of the mobile phone of an operator through a Bluetooth module, the unlocking authorization is verified, and the electromagnetic lock in the lock body is controlled to electrify, the lock cylinder is released from the lock tongue in the lock body, the lock cylinder can move upward along a lock cylinder hole under the elastic effect of an energy accumulating spring to complete unlocking; the control unit is used for collecting the well lid posture and underground gas density information through an inclined vibration monitor module and a gas sensor module, and reporting alarm information and periodically collected data information based on a LoRa communication module. The well lid linkage system has a simple structure, can be used for automatically monitoring unlocking authority verification, underground gas density and well lid posture, so that potential safety hazard can be effectively eliminated for undergroundoperation and inspection personnel.

Description

Technical field [0001] The invention is a manhole cover linkage system, in particular to a wireless remote controllable manhole cover linkage system. Background technique [0002] Manholes are also called manhole wells. Common manholes include rain, sewage inspection wells, cable manholes, and communication manholes. For manholes in certain industries, such as municipal, gas, electric power and other industries, regular manual inspections are required, and underground operations are carried out as needed. The above-mentioned manholes are generally not allowed to be opened or entered illegally. Therefore, the wells have been in a closed environment for a long time, and there are more toxic gas deposits. Downhole operations are prone to poisoning, coma and even suffocation. In response to this problem, the Safety Production Management Law stipulates that downhole operations must strictly abide by the operating procedures. Before downhole operations, inspection or maintenance perso...
