Cooling water circulation system of water cooling protection sleeve of camera in high-temperature environment

Abstract

The invention relates to a cooling water circulation system of a water cooling protection sleeve of a camera in a high-temperature environment. The system comprises a water cooling outer sleeve and a water cooling inner sleeve, wherein a water separation sleeve is arranged between the water cooling outer sleeve and the water cooling inner sleeve so as to form an outer sandwiched layer and an inner sandwiched layer; a circulation channel is reserved at the front end of the water separation sleeve; the rear end of the water separation sleeve is fixed on a rear flange; the front end of the water cooling outer sleeve is fixed on a front flange; the rear end of the water cooling outer sleeve is fixed on the rear part of the water separation sleeve; the front end and the rear end of the water cooling inner sleeve are fixed on the front flange and the rear flange, respectively; the rear end surface of the water separation sleeve is provided with a water inlet; the rear end surface of the water cooling sleeve is provided with a water outlet. According to the invention, the problem that a camera and a camera lens are damaged frequently because the circulation of cooling water is not smooth, a circulation dead corner occurs at the front end of the water cooling protection sleeve, cooling water at the front end of the water cooling protection sleeve cannot be circulated, and the water cooling protection sleeve is burned to be leaked because of local overheating is solved, so that the device maintenance working time is shortened, and the device maintenance cost is lowered. The system has the advantages of reasonable structure design, processing simplicity, low cost and the like.

Description

technical field [0001] The invention relates to a monitoring camera accessory, in particular to a cooling water circulation system for a water-cooling protective cover of a camera in a high-temperature environment. The system is suitable for cooling and protection of monitoring cameras under the conditions of high-temperature industrial production lines in steel, electric power, metallurgy, cement, petrochemical and other industries. Background technique [0002] The camera protective cover is an important component in the surveillance system, which is used to protect the reliability of the camera and lens and prolong its service life. In addition, the protective cover can also try to prevent human damage to the camera and lens. Ordinary outdoor camera shields are only suitable for outdoor monitoring in general environments, and are suitable for ambient temperatures of -5 to 45°C. However, for the on-site radiation temperature above 200°C in the high-temperature industrial...

AI Technical Summary

Problems solved by technology

[0003] The existing water-cooled protective cover has complex processing technology, poor cooling water circulation, and easy to appear cycle dead angles, resulting in damage to the camera, and malfunctions in the field of use in high-temperature environments

The reason for its unstable operation is that the welding process of the sandwich partition is complicated and the welding is not firm. The cooling water does not pass through the front end of the water cooling jacket, but directly flows out from the upper water outlet through the gap between the partition and the inner jacket.

Due to the poor circulation of cooling water, the front end of the water-cooling protective cover has a dead angle of circulation, and it is close to high temperature for a long time, causing the water-cooling protective cover to burn and leak, and even damage the camera and lens.
