Problems solved by technology

[0003] Since the camera is set outdoors, in foggy weather, the outer surface of the transparent protective cover outside the camera is very likely to condense a layer of fog beads, which will seriously affect the clarity of the camera shooting, especially in autumn and winter, night The outdoor temperature is low, and the fog beads will also form hard-to-scrape frost on the surface of the transparent cover, resulting in a long-term low level of camera clarity at night

Embodiment 2

[0025] refer to image 3 , the difference from Embodiment 1 is that a water storage tank 13 is provided in the base 1, a semi-circular chute 11 is provided in the transparent cover 9 cover body, and the sealing sliding connection in the chute 11 has an initial position corresponding to the permanent magnet block 6 The two ends of the chute 11 are connected with the water storage tank 13 through the conduit 14, and the chute 11 and the water storage tank 13 are filled with water, and the part of the conduit 14 located in the water storage tank 13 is submerged below the water surface .

[0026] It should be noted that the electrical components of the camera are all installed in the base 1, the water storage tank 13 is close to the installation position of the electrical components and a heat conduction sheet is provided in the water storage tank 13, one end of the heat conduction sheet is submerged below the water surface in the water storage tank 13, and one end Located at the...

Abstract

The invention discloses a fog-proof outdoor monitoring camera, which comprises a base horizontally fixed on a building, a lens arranged at the lower end of the base and capable of horizontal rotation, and a hemispherical transparent cover arranged at the lower end of the base and surrounding the lens. A base plate extending along the rear of the lens and fixedly connected with the lens is provided above the lens, and an electromagnet is fixedly connected to the end of the base plate. In the present invention, by setting a scraping mechanism, a humidity sensor, an electromagnet, an induction coil, a water storage tank, a conduit and a chute, when the surface humidity of the transparent cover is relatively high, the humidity sensor can control the electromagnet to be energized to generate an attractive force and simultaneously absorb The permanent magnet block and the arc-shaped slider are close, and at the same time, the movement of the permanent magnet block reduces the magnetic flux of the induction coil, and an induced current is generated to reverse the electromagnet electrode, pushing the permanent magnet block and the arc-shaped slider back to the original position, thereby driving the scraping bar to The fog beads condensed on the outer surface of the transparent cover are scraped off.

Description

technical field [0001] The invention relates to the technical field of monitoring equipment, in particular to a fog-proof outdoor monitoring camera. Background technique [0002] Existing outdoor cameras generally include a pedestal and a camera arranged below the pedestal, and a hemispherical transparent glass protective cover is also provided outside the camera to protect the camera from collisions with foreign objects. [0003] Since the camera is set outdoors, in foggy weather, the outer surface of the transparent protective cover outside the camera is very likely to condense a layer of fog beads, which will seriously affect the clarity of the camera shooting, especially in autumn and winter, night The outdoor temperature is low, and the fog beads will also form hard-to-scrape frost on the surface of the transparent cover, resulting in a long-term low level of camera clarity at night. Contents of the invention [0004] The object of the present invention is to solve t...
