Heat-preservation anti-freezing holder

Abstract

The invention discloses a heat-preservation anti-freezing holder. The heat-preservation anti-freezing holder comprises a shell, an upper cover, a support platform, a bearing, a horizontal stepping motor, a horizontal decelerator, a horizontal worm, a horizontal worm wheel, a horizontal transmission shaft, a pitching stepping motor, a pitching decelerator, a pitching worm, a pitching worm wheel and a pitching transmission; the bearing, the horizontal stepping motor, the horizontal decelerator, the horizontal worm, the horizontal worm wheel, the horizontal transmission shaft, the pitching stepping motor, the pitching decelerator, the pitching worm, the pitching worm wheel and the pitching transmission are arranged in the shell; the shell is a hollow cavity; a resistance wire is arranged on the inner wall of the cavity; the resistance wire is connected to a temperature controller, and used for adjusting the temperature in the holder; a thermal insulation material is filled in the cavity of the shell, so that the temperature in the cavity is kept in a fixed range; a bearing frame arranged on the inner wall of the shell is an empty cavity; and the thermal insulation material is filled in the empty cavity. The heat-preservation anti-freezing holder disclosed by the invention has the advantages of being low in cost, simple in structure, thermal-insulated and anti-freezing, and can work in an atrocious weather.

Description

technical field [0001] The invention relates to the technical field of rail transit security monitoring, in particular to a thermal insulation and antifreeze cloud platform. Background technique [0002] With the enhancement of social security awareness and the development of video surveillance technology, PTZ has been widely used in various industries, such as power system, rail transit, financial system, etc. Especially in the rail transit industry, in order to ensure the safe operation of trains, it is necessary to monitor the safety of the railway line at all times, such as the depth of snow on the track, whether there is foreign matter intrusion, etc. However, the environment of the railway line is very complicated, especially in the north where heavy snow and low temperature often occur. In such an extreme environment, ordinary pan / tilts cannot adapt, so a kind of heat preservation and antifreeze pan / tilt is needed to work in this extreme environment. [0003] Patent ...

AI Technical Summary

Problems solved by technology

However, the environment of the railway line is very complicated, especially in the north where heavy snow and low temperature often occur. In such an extreme environment, ordinary pan / tilts cannot adapt, so a kind of heat preservation and antifreeze pan / tilt is needed to work in this extreme environment.

[0003] Patent CN 103962323 A discloses an anti-icing structure and control method for an outdoor pan-tilt camera. An anti-icing structure is installed between the pan-tilt shell and the shield shell to ensure that the equipment works in a low-temperature environment, but the structure is relatively Complicated and not very practical
