Lifting type closed circuit television system with anti-shaking structure

Abstract

The invention discloses a lifting type closed circuit television system which is provided with a structure for winding or unwinding a steel wire rope on or from a winding drum so as to lift a closed circuit television camera. The lifting type closed circuit television system comprises a main body, a lifting body, a containing structure, limiting pieces, an upper contact part, a lower contact part, at least one guide roller and fixing tools, wherein the main body is arranged at a specified height and is provided with the winding drum and a first driving motor for providing rotating force for the winding drum, the lifting body is hung on the steel wire rope, the closed circuit television camera is installed on the lifting body, the lower portion of the containing structure is open so that the containing structure can be combined with the lifting body, the limiting pieces are clamped by a clamping part of the lifting body to provide a function of preventing the lifting body from falling, the upper contact part and the lower contact part are arranged on the main body and the lifting body respectively and make contact with each other when the lifting body is combined with the main body, the guide rollers are arranged on the side portion and the upper portion of the winding drum and used for supporting the steel wire rope unwound from the winding drum and guiding the steel wire rope into the containing structure, and the fixing tools are used for applying pressure to either the upper contact part or the lifting body in a state where the lifting body ascends and is combined with the main body. According to the lifting type closed circuit television system, the closed circuit television camera can be prevented from shaking.

Description

technical field [0001] The present invention relates to a lift-type closed circuit television (CCTV) system, and more particularly to a lift-type CCTV system having a structure in which a wire rope is wound or unwound to a reel to lift and lower a CCTV camera. Background technique [0002] Generally speaking, closed-circuit television cameras are installed on the pillars of highways and other car-only roads to collect current data on vehicle congestion and various traffic data related to vehicle driving or to investigate and deal with vehicle speeding. This CCTV camera is fixed in a certain direction to ensure that it can capture a specific location. [0003] However, since CCTV cameras are installed at high places, they frequently suffer from functional degradation due to changes in the external environment such as dust deposition and wind when used for a long period of time. In addition, if you want to repair or clean the CCTV cameras, you need to rent expensive equipment...

AI Technical Summary

Problems solved by technology

[0007] If the lifting body shakes due to wind, etc., the camera will also shake at the same time, so the function of the CCTV may be reduced, and the camera may fall when there is a strong wind
