Security monitoring camera capable of automatically removing obstruction

Abstract

The invention provides a security monitoring camera capable of automatically removing an obstruction, and the camera comprises a housing, the housing is provided with an air hole, an annular groove and an arc-shaped surface, a photoresistor is disposed between a lens and the air hole, a metal ring is disposed in the housing, fan blades are disposed around the outer side of a rotating ring, and theinner side end of the interior of the rotating ring is connected with a blocking column. Trapezoidal magnetic blocks are connected to the inner side ends of the annular blades, metal sheets are arranged on the right sides of the trapezoidal magnetic blocks, and coils corresponding to the trapezoidal magnetic blocks are arranged on the right side in the rotating ring. A magnetic field generated bythe coil pushes the trapezoidal magnetic block to move leftwards, and the trapezoidal magnetic block extrudes and crosses the bumping post and the first spring; meanwhile, the resistance in the photoresistor is minimum, the blower device connected with the photoresistor in series is changed into a closed circuit from an open circuit, the blower device sucks air through the air holes, airflow in the air holes adsorbs the shielding object to get close to the annular blade on one hand, and on the other hand, the fan blades rotate in the rotating ring, and the rotating ring drives the annular blade to annularly cut the shielding object.

Description

technical field [0001] The invention belongs to the technical field of security monitoring equipment, in particular to a camera for security monitoring that can automatically remove obstructions. Background technique [0002] The security monitoring system uses optical fiber, coaxial cable or microwave to transmit video signals in its closed loop, and forms an independent and complete system from camera to image display and recording. Security monitoring can reflect the monitored objects in real time, vividly and truly, which not only greatly prolongs the observation distance of human eyes, but also expands the functions of human eyes. [0003] Although the existing security monitoring camera equipment can achieve high-precision detection, when the thief artificially puts the camera equipment on a plastic bag or a cloth cover, it is because the thief deliberately changes the body shape when covering it. , but it is inconvenient to operate when stealing, and the security mon...

[0003] Although the existing security monitoring camera equipment can achieve high-precision detection, when the thief artificially puts the camera equipment on a plastic bag or a cloth cover, it is because the thief deliberately changes the body shape when covering it. , but it is inconvenient to operate when stealing, and the security monitoring camera equipment cannot perform normal recording work after being blocked, which leads to the loss of people's property and fuels the arrogance of the thief
