Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments.

[0027] A structure to prevent condensation of monitoring equipment such as figure 1 As shown, it includes a device casing 1, a protective cover 2, and a pressure regulating air bag 4. The inside of the device casing is integrally formed with a cylindrical platform 6 with external threads, and the end face of the equipment casing in the center of the cylindrical platform is coaxially formed with a through hole 7. The cylindrical platform is coaxially threaded to connect the protective cover, the protective cover is sealed with a pressure-regulating airbag, and the inside of the pressure-regulating airbag communicates with the air outside the equipment shell through a through hole, and the bottom center of the protective cover is formed with a protective cover hole 5, so The space between the protective cover and the pressure re...

Abstract

The invention relates to a structure for preventing monitoring equipment from condensation, which comprises an equipment shell, a protection cover and a pressure-adjusting air bag. The equipment shell is internally provided with an integratedly-made cylindrical platform with outer thread; a through hole is made in the end surface, in the middle of the cylindrical platform, of the equipment shell; the cylindrical platform is in coaxial thread connection with the protection cover; the protection cover is internally provided with the pressure-adjusting air bag in a sealing mode; the inner part of the pressure-adjusting air bag is communicated with the air outside the equipment shell via the through hole; the middle of the bottom part of the protection cover is provided with a protection cover hole; and the space between the protection cover and the pressure-adjusting air bag is communicated with the air inside the equipment shell via the protection cover hole. According to the structure of the invention, the structure is simple; when temperature rises, the pressure inside the shell is increased, the size of the pressure-adjusting air bag is reduced, the volume of the shell is increased, the inner pressure is reduced consequently until the inner pressure is balanced with the outer pressure; and when the temperature falls, the inner pressure of the shell is reduced, the size of the pressure-adjusting air bag is increased, the volume of the shell is reduced, the inner pressure is increased consequently until the inner pressure is balanced with the outer pressure.

Description

technical field [0001] The invention belongs to the technical field of video monitoring, and relates to front-end equipment, in particular to a structure and method for preventing condensation of monitoring equipment. Background technique [0002] With the development of video surveillance technology, the performance requirements for front-end video surveillance equipment continue to increase, especially the requirements for image clarity and quality. [0003] At present, monitoring equipment installed outdoors usually has "condensation" on the inner wall of the window. "Condensation" seriously affects the clarity of video images and reduces the quality of monitoring. High protection performance is the cause of "condensation" main reason. [0004] In order to prevent the equipment installed outdoors from infiltrating rainwater, manufacturers usually make the sealing measures of the monitoring equipment casing very tight, generally reaching IP66 and IP67 protection levels. ...
