Embodiment Construction

[0010] refer to Figure 1~2 , a well cover induction switch device, including a well frame 1 and a well cover 2, the well cover 2 is installed on the well frame 1, the well cover 2 is fixedly installed with a latch 4 with a magnet, and the inner wall of the well is installed with a latch 4 to cooperate with The electric control lock 5 is characterized in that: Hall components are installed in the electric control lock 5, and after the manhole cover 2 is covered, the semicircle turntable of the electric lock rotates to block the circular latch to achieve the locking effect, and the semicircle The turntable rotates 180 degrees to realize unlocking.

[0011] When the manhole cover 2 with the magnetic latch 4 is closed, the magnetic field acting on the Hall device will change, and the output signal of the Hall device will change accordingly, and the intelligent measurement and control unit in the electric control lock 5 will transmit the detection signal to the upper position c...

Abstract

The invention discloses a well cover sensing switch device, which comprises a well frame and a well cover. The well cover is arranged on the well frame; a clamping latch with a magnet is fixedly arranged on the well cover; an electric control lock matched with the clamping latch is arranged on an inner wall of a well; and a Hall element device is arranged in the electric control lock. With the adoption of the well cover sensing switch device, the centralized monitoring management of pipe well resources can be realized and an alarm function is also realized when the well is illegally uncovered and the well cover is stolen. The sensing Hall element device is arranged inside the electric control lock, the sensing sensitivity is high and the state judgment is correct. In addition, no any one part of the electric control lock control part is positioned on the well cover, so that the problem of waterproofing and sand-proofing is radically solved, and the well cover sensing switch device has a good anti-theft anti-destroy function.

Description

technical field [0001] The invention relates to an automatic control and the field of the Internet of Things, in particular to a manhole cover induction switch device. Background technique [0002] At present, public resources such as urban communication and energy are connected to suppliers and users through underground network pipelines. Management and maintenance of these underground pipeline network resources are mainly realized through manholes. Underground pipelines provide us with an efficient way of transporting resources, but they also bring great crises to the city. Manhole covers are stolen and man-made damage leaves a large hole in the road surface, which greatly affects traffic safety and causes unsustainable estimated loss. At present, a small number of electronically controlled locks in use can realize the anti-theft function of the manhole cover. The control mechanism uses a magnetic suction mechanism to control the tongue to block the movement of the lock ...
