Self-adjusting intelligent household security camera
Technical Field
The invention belongs to the field of security monitoring, and particularly relates to a self-adjusting intelligent household security camera.
Background
With the development of security monitoring technology, more and more families can install security cameras outdoors, and for the existing outdoor security cameras, the problem of strong backlight is generally faced, namely when the direction in which the lens faces has strong background illumination, if the camera just faces the sun, the brightness of an object image shot by the camera is extremely low, the image processing module can only integrally increase the brightness of the shot image, and the definition of the adjusted image is very limited and even fuzzy.
Therefore, a sun shield is generally arranged above a lens of an outdoor security camera at present, the structural position of the sun shield is fixed, and the illumination intensity of sunlight is different, so that the shading effect of the sun shield is not obvious when the illumination is strong, and the problem that the sun shield obstructs the lighting of the camera when the illumination is weak occurs; the camera is arranged outdoors mostly, and at the direct irradiation of sunshine, the in-process of inner member work simultaneously can lead to its inside programming rate very fast, and when the temperature was higher, easily lead to the camera damage, causes the wasting of resources.
Therefore, a self-adjusting intelligent household security camera is provided to solve the problems.

In order to achieve the purpose, the invention adopts the following technical scheme: a self-adjusting intelligent household security camera comprises a shell and a support fixedly connected with the bottom of the shell, wherein a camera is arranged in front of the shell, the shell is made of a light-transmitting material, a push plate is connected in the shell in a sealing and sliding manner, silver bromide powder is filled in a closed space formed by the push plate and the shell, a light shielding plate is fixedly connected on the side wall of the push plate, a protection plate is arranged above the camera, the protection plate is a transparent glass plate, a sliding cavity communicated with the inside of the shell is arranged in the protection plate, the other end of the light shielding plate extends into the sliding cavity and is connected with the side wall of the sliding cavity in a sliding manner, a plurality of permanent magnetic strips are equidistantly distributed on the upper surface of the light shielding plate, a plurality of elastic cleaning ropes arranged in parallel with the permanent magnetic strips are arranged on the upper surface of the protection plate, and, both ends of the elastic cleaning rope are fixedly connected with the protection plate, and a ferromagnetic sheet is fixedly attached to the elastic cleaning rope.
The invention has the advantages that:
when the illumination intensity of sunlight is strong, light rays irradiate to the silver bromide powder inside through the transparent shell, the silver bromide powder is decomposed into silver simple substances and bromine gas under the catalysis of illumination, the bromine gas expands to push the push plate to move towards the direction of the camera, and then the light shielding plate is driven to move towards the sliding cavity, namely, the light shielding plate extends towards the direction of the camera, so that the shielding effect of the light rays at the camera is improved, and the camera can be ensured to normally shoot; when the illumination intensity of sunshine is less than, silver simple substance and bromine gas are combined again and are silver bromide, then under the atmospheric pressure effect, the push pedal drives the light screen and removes to casing inside, reduces the scope of sheltering from to camera department light, avoids causing the influence to the monitoring range of camera.
When illumination intensity changes, the push pedal drives the light screen and slides in sliding cavity, then, drive a plurality of permanent magnetic stripe and remove, a plurality of permanent magnetic stripe are at the in-process that removes, under the magnetic force effect, produce the appeal to the ferromagnetic piece that is close to one by one in turn, in-process when one of them permanent magnetic stripe is close to ferromagnetic piece, produce bigger and bigger appeal to ferromagnetic piece, then, the clean rope of pulling elasticity takes place deformation, keep away from the back when permanent magnetic stripe, the clean rope of elasticity resets and shakes, can strike off the dust of guard plate upper surface accumulation, prevent to cause the influence to the daylighting of camera.
The distance between the two permanent magnet strips is larger than the distance between the two elastic cleaning ropes.
The axial direction of the permanent magnetic strips is vertical to the movement direction of the shading plate.
Rotate on the inside wall of casing and be connected with the threaded rod, the threaded rod run through the push pedal and with push pedal threaded connection, the fan has been cup jointed to the threaded rod external fixation, the louvre has been seted up on the lateral wall of casing, and when atmospheric pressure promoted the push pedal and remove, drive threaded connection's threaded rod with it and rotate, drive the fan rotation then for the air current flow speed of louvre department to promote the inside heat exchange with the external world of casing, played good heat dissipation effect.
