Closed-circuit television monitoring device based on centrifugal force automatic sharpening

Abstract

The invention provides a closed-circuit television monitoring device based on centrifugal force automatic sharpening. The device comprises a monitoring main body. Cleaning rollers are movably mountedon the left sides of the lenses through rollers. The outer side of the roller is fixedly sleeved with a magnetic ring. An electromagnet is fixedly installed at the bottom of the sliding groove, a windwheel is fixedly connected to the outer side of the rotating shaft and located on the outer side of the monitoring body in a sleeving mode, a ball is connected to the outer side of the rotating shaftand located in the monitoring body through a tension spring, and a contact switch corresponding to the electromagnet is fixedly installed in the monitoring body and located on the outer side of the ball. When wind power is too large, the wind wheel drives the rotating shaft to rotate, the ball body drives the tension spring to deform and stretch under the action of centrifugal force, the ball body makes contact with the contact type switch, the electromagnet is powered on and has magnetism, the idler wheel is pushed to move upwards, and in the upward moving process of the idler wheel, the cleaning roller scrapes and cleans the surface of the lens. And then the roller slides down along the closed groove to extrude the baffle plate down and fall back into the vertical groove.

Description

technical field [0001] The invention belongs to the technical field of closed-circuit television monitoring, and in particular relates to a closed-circuit television monitoring device for automatic clearing based on centrifugal force. Background technique [0002] As an important part of the security system, closed-circuit television monitoring has the functions of early warning and post-event prevention. It plays an irreplaceable role in the fields of traffic management, public security management and community management. Closed-circuit television monitoring and fire protection and access control After the security system is linked, it will play a better effect, so it is widely used. [0003] An extremely important device in the CCTV monitoring system is the monitoring camera. In order to obtain a good monitoring effect, the lens cleanliness of the monitoring camera must first be ensured. In many outdoor CCTV monitoring, the structure of the camera is relatively simple, ge...

Problems solved by technology

[0003] An extremely important device in the CCTV monitoring system is the monitoring camera. In order to obtain a good monitoring effect, the lens cleanliness of the monitoring camera must first be ensured. In many outdoor CCTV monitoring, the structure of the camera is relatively simple, generally Install a protective cover on the camera to prevent rain, but in the case of strong wind, the deflection of the rain will become larger, and it will often be adsorbed on the lens of the surveillance camera, resulting in blurred and clear surveillance shots The degree becomes worse, which is not conducive to the normal progress of security work
