Abstract

The invention belongs to the field of video monitoring, and provides a rain wiper of a camera protective cover and a video monitoring system; the rain wiper comprises a substrate, a reflective optical coupler, a fixing frame, a sliding block, a connecting sheet, a guide rail, a driven wheel, a belt, a pinch roller, a belt wheel, a pressing sheet, a spring, a shell, a motor, a sealing rubber bar, a large rain wiper arm, a small rain wiper arm, a rubber bar clamping plate and a rubber bar; the connecting sheet and the sliding block are fixed together; the connecting sheet is used for clamping the belt; the sliding block is sheathed on the guide rail; the connecting sheet is connected with the large rain wiper arm; the large rain wiper arm is connected with the small rain wiper arm; the small rain wiper arm is connected with the rubber bar clamping plate; the rubber bar clamping plate is connected with the rubber bar; and the spring is further connected between the large rain wiper arm and the small rain wiper arm. In the invention, the structure such as a reflective optical coupler is adopted so that the work area is rectangular and the view window blind side splodge is effectively eliminated; and the belt torque is born on the motor shaft so that the damage rate of the rain wiper is reduced.

Description

technical field [0001] The invention belongs to the field of video monitoring, in particular to a camera protective cover wiper and a video monitoring system. Background technique [0002] At present, the wiper is a frequently used device on the camera protective cover. Its function is to sweep away the rain, snow and dust on the glass of the camera. Therefore, it plays an important role for the camera. The electric wiper is composed of a motor, a crank, a transmission rod, a brush arm and a brush blade. When the motor rotates, it drives the crank and the transmission rod to work, so that the brush arm and the brush piece sweep away the rain, snow and dust on the glass of the camera. Adopt this wiper device, the area that the wiper device brushes out is fan-shaped, and places such as dirt, raindrop etc. are not brushed on the many dead corner areas on the window glass. The output shaft of the traditional wiper motor bears the force and rotational torque of the wiper in t...
