The invention relates to a well lid lock adopting non-contact power supply magnetic force transmission and electromagnetic reset, and belongs to the technical field of locks. The well lid lock comprises a well lid lock body, and a matched electronic key, and is characterized in that the well lid lock body comprises a front cover, a circuit board, a motor, a cam magnet, a rear cover, a drive magnet, a drive shaft and a lock shell; the motor for controlling the drive shaft to operate and the circuit board for controlling the motor are fixed into the rear cover; the circuit board is connected with a wireless receiving coil in the front cover; the cam magnet is arranged in the cam of the motor; and the drive magnet is arranged in the drive shaft. The lock provided by the invention is not provided with a power supply or a spring, and is powered through the electronic key when the lock is required to be unlocked, so that the lock can adapt to long-term soaking in sewage under a well lid, a vibration environment and other severe environments.
Description
technical field [0001] The invention relates to a manhole cover lock adopting a non-contact type for electromagnetic force transmission and electromagnetic reset, which belongs to the technical field of locks. Background technique [0002] With the development of modern cities, there are many pipe networks under the road, such as power cables, gas pipes, heat pipes, and communication cables. In order to facilitate maintenance, there are inspection wells in the road, and many well covers are arranged. However, the phenomenon of manhole cover loss and illegal opening often occurs, and once it occurs, it may cause great harm to property and personal safety. Most of the existing electronic manhole cover locks are electric bolt locks. The most basic principle of electric bolt locks is to use codes to control the electromagnet, and the expansion and contraction of the electromagnet drives the bolt, so as to directly realize the purpose of unlocking and locking. The environment u...
