Ball camera internal type anti-icing and anti-fogging device

Technical Field

The utility model belongs to the technical field of the anti-icing defogging equipment of internal ball machine, concretely relates to ball type camera internal type anti-icing and anti-fogging device.

Background

In order to protect a lens on a camera, a camera of the existing camera is generally built in a transparent glass or plastic cover. However, when the temperature difference between day and night is large, the temperature of the camera is warmed up in the daytime, and the surface temperature of the camera cannot change in time along with the change of the temperature, so that a layer of water mist is attached to the outer surface of the cover body because the temperature of the outer surface of the cover body is too low relative to the external temperature, and the shooting quality of the camera inside the cover is seriously affected.

the traditional water mist removing method has two types: firstly, wiping is carried out by adding a mechanical structure; and secondly, keeping the mixture relatively dry by adding a drying agent. Both of the above methods increase their complexity and require increased maintenance frequency, which is not suitable for the operating environment of the power camera.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

Example 1: as shown in fig. 1-3, an internal anti-icing and anti-fogging device for a dome camera comprises a silica gel heating sheet 1 and an internal temperature sensor 2, wherein the silica gel heating sheet 1 and the internal temperature sensor 2 are fixedly connected to the dome camera 3 and are located in an outer cover shell 4 of the dome camera 3 at the position of a camera, the silica gel heating sheet 1 and the internal temperature sensor 2 are connected to a controller, and the controller is connected to a human-computer interaction interface.

Preferably, above-mentioned ball camera internal type anti-icing and anti-fog device is still including installing outside temperature and humidity sensor 5 and baroceptor 6 in ball camera 3 outside and installing outside temperature sensor 9 on outer cover casing 4, outside temperature and humidity sensor 5 and baroceptor 6 and outside temperature sensor 9 all are connected with the controller, through monitoring outside humiture and atmospheric pressure size and outer cover casing temperature, can match with inside temperature automatically, keep inside temperature for the outer cover casing does not produce the optimum temperature range of ice-cube and fog, thereby reach the effect of prevention play fog and removal water smoke.

Preferably, the silica gel heating sheet 1 is arranged in the heat insulation groove 7, the aluminum alloy heat dissipation scaly sheet plate 8 is adopted to fix the silica gel heating sheet 1 on the heat insulation groove 7, the heat insulation groove 7 is fixedly connected onto the spherical camera 3, and the aluminum alloy heat dissipation scaly sheet plate 8 is fixed on the heat insulation groove 7 through screws.

The use principle is as follows: the difference value between the saturated vapor pressure, the dew condensation dew point temperature and the temperature of the outer shell under the current environment is calculated by collecting the temperature, the relative humidity and the atmospheric pressure of the surrounding environment of the dome camera and the temperature of the inner part of the outer shell of the dome camera. When the set threshold value is reached, the controller controls the heating module to heat the outer cover shell and the internal environment of the outer cover shell, so that the effects of preventing fogging and removing water mist are achieved.
