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 1

[0019] refer to Figure 1-2 , a waterproof and fog-proof outdoor monitoring camera, including a base 1 horizontally fixed on a building, a lens 2 arranged at the lower end of the base 1 and capable of rotating horizontally, and a hemispherical lens 2 arranged at the lower end of the base 1 and surrounding the outside of the lens 2 A transparent cover 9, a substrate 4 extending along the rear of the lens 2 and fixedly connected to the lens 2 is provided above the lens 2, an electromagnet 5 is fixedly connected to the end of the substrate 4, and the lower end of the base 1 is located at the transparent cover 9 and is fixedly connected with a semi-circular The slide rail 8 is slidably connected with an arc-shaped permanent magnet block 6 attached to the inner surface of the transparent cover 9 , and an induction coil 3 coupled with the electromagnet 5 is sleeved on the corresponding permanent magnet block 6 above the lens 2 .

[0020] The outer surface of the transparent cover 9 ...

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 water-mist-proof outdoor monitoring camera which comprises a base which is horizontally fixed on a building, a lens which is arranged at the lower end of the base and can horizontally rotate, a hemispherical transparent cover which is arranged at the lower end of the base and surrounds the lens, a base plate which extends along the rear of the lens and is fixedly connected with the lens is arranged above the lens, and an electromagnet is fixedly connected to the tail end of the base plate. A scraping mechanism, a humidity sensor, an electromagnet, an induction coil, awater storage tank, a guide pipe and a sliding groove are arranged; when the humidity of the surface of the transparent cover is high, the humidity sensor controls the electromagnet to be electrified; meanwhile, the permanent magnet block moves to enable the magnetic flux of the induction coil to be reduced, induced current is generated to enable the electromagnet electrode to rotate reversely, the permanent magnet block and the arc-shaped sliding block are pushed back to the original positions, and therefore the scraping strip is driven to scrape mist beads condensed on the outer surface ofthe transparent cover.

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...
