Energy-saving anti-freezing insulation cover

Abstract

The invention discloses an energy-saving anti-freezing insulation cover which comprises a cover top, a cover wall, a cover bottom, an electric heating device, and a temperature controller. The cover top is connected with the cover wall by means of sealing. The cover wall sleeves the cover bottom. The electric heating device and the temperature controller are arranged on the cover bottom. The temperature inside the anti-freezing cover can be kept above 0 DEG C. The cover has an obvious anti-freezing effect, and there is no freezing phenomenon. The intact rate of equipment is improved greatly. The service life of camera monitors in cold regions is prolonged.

Description

technical field [0001] The invention relates to the field of antifreeze technology, in particular to an energy-saving antifreeze and heat preservation cover. Background technique [0002] The current surveillance cameras have two types: dome camera and bolt camera. No matter which one, only dustproof and waterproof grades are required. In order to ensure that the equipment is dustproof and waterproof, a hemispherical or cylindrical shell is usually installed outside the camera. These shells do not have the function of heat preservation, and the ultra-low temperature environment often causes electronic components to malfunction. Ice and snow will cause ice and snow to cover the surface of the equipment, affecting the field of view and clarity of the camera. At the same time, the pan-tilt equipment that controls the rotation of the surveillance camera is connected Outside the camera casing, it is exposed in a freezing environment. Under the cover of ice and snow, the rotating ...

Problems solved by technology

These shells do not have the function of heat preservation, and the ultra-low temperature environment often causes electronic components to malfunction. Ice and snow will cause ice and snow to cover the surface of the equipment, affecting the field of view and clarity of the camera. At the same time, the pan-tilt equipment that controls the rotation of the surveillance camera is connected Outside the camera casing, it is exposed in a freezing environment. Under the cover of ice and snow, the rotating part often freezes and cannot work. The normal working temperature range of the metal gimbal equipment is not lower than -30°C, and the minimum working temperature of the plastic gimbal is -15°C. Currently, One of the ways to solve the anti-freezing of monitoring equipment is to reduce the contact surface of the rotating part of the turntable or pan-tilt. In addition, a simple thermal insulation material is used outside the surveillance camera. The thermal insulation capacity of the equipment is limited. At present, no anti-freezing camera monitoring with the same technology has been found. protecting mask
