Detailed Description
In order that those skilled in the art will better understand the technical solutions of the present invention to be implemented, the present invention will be further described with reference to the following specific embodiments and accompanying drawings.
In the invention, the front and the front sides are the sides of the device which is provided with a camera and can shoot pictures; the rear and the rear side are the sides which deviate from the shooting picture after the device is installed.
The invention provides an artificial intelligence monitoring camera capable of being adjusted in a rainproof manner, which comprises a camera and a mounting seat 1 for mounting the camera, wherein a rainproof cover 2 is mounted at the top of the mounting seat 1, the mounting seat 1 is in sliding connection with the rainproof cover 2, and the rainproof cover 2 can be mounted on the mounting seat 1 to slide transversely in the length direction; an installation cavity 11 for placing a camera is formed in the bottom of the installation base 1, a controller 3 for controlling the rain cover 2 to slide is installed in the installation cavity 11, an illuminating lamp 4 is installed at the top of the installation cavity 11, and the light irradiation direction of the illuminating lamp 4 faces the front of the installation cavity 11; the controller 3 is electrically connected with an external power supply after being electrically connected with the illuminating lamp 4; or the controller 3 and the illuminating lamp 4 are connected with the camera in series and then electrically connected with an external power supply.
The inner top of the mounting seat 1 is a solid part 12, the solid part 12 of the mounting seat 1 is provided with a rainwater flow guide channel 121, the top opening of the rainwater flow guide channel 121 is positioned at the top of the solid part 12 of the mounting seat 1, and the side opening of the rainwater flow guide channel 121 is positioned at the rear side of the solid part 12 of the mounting seat 1; the side opening of the rainwater diversion channel 121 can be connected with a sewer pipe or the side opening of the rainwater diversion channel 121 is provided with a sieve plate 5; a water flow meter 6 is arranged in the rainwater diversion channel 121, and the water flow meter 6 is electrically connected with the controller 3; the top of the rain cover 2 is provided with a skylight opening corresponding to the top opening of the rainwater diversion channel 121, and a filter screen 21 is arranged in the skylight opening.
