Abstract
The utility model discloses a pollution covering device for keeping a video head to be clearly observed. The upper part and the lower part of an engine body (1) are respectively provided with an upper roller (2) and a lower roller (8), wherein a cover membrane (4) is connected between the upper roller (2) and the lower roller (8); the middle part of the engine body (1) is provided with a groove which is matched with the protruding part of the video head (6); the engine body (1) is provided with a motor; and the upper roller (2) or the lower roller (8) is connected with the motor (9). A rolling wheel is driven to tighten by adopting a motor; the polluted cover membrane is moved out; the clear part is exposed; and the definition of the observed picture is protected, thereby being beneficial for the distortionless observation. The pollution covering device is compact in structure and convenient in operation and is easy to realize automatic control.
Description
Technical field
The utility model relates to the auxiliary appliance technology of photography and vedio recording, prevents during especially for outdoor or field operation that camera lens is contaminated and keeps the dirty device of screening of the clear observation of video heads.
Background technology
In the known technology; In the place of some rescues scenes and particular surroundings, need lay the real-time Transmission that video monitoring device is used for field condition, because on-the-spot special environment; Can produce greasy dirt; Steam, materials such as dust pollute the observation eyeglass of video monitoring device, cause the observation fuzzy pictures and can't gather the observation picture.
Yet the patent application of relevant improvement technical scheme is not seen open.
Summary of the invention
The purpose of the utility model provides a kind of dirty device of screening that keeps the clear observation of video heads.
Realize that the measure of the utility model goal of the invention comprises: body upper and bottom are installed roller and lower roll respectively; There is the symphysis of screening to connect between top roll and the lower roll; The body middle part is fluted matches with the protuberance of video heads, and motor is installed on the body, and top roll or lower roll are connected with motor.
In the utility model, adopt the driven by motor running roller to tighten and move out contaminated screening film, expose part clearly, the definition of protection observation picture helps observing undistorted, and compact conformation is easy to operate, is easy to realize automatic control.
Description of drawings
Fig. 1 is the utility model structural representation
Reference numeral: body 1, top roll 2, last expansion tightening wheel pair 3 hides film 4, casing 5, video heads 6, following tensioner wheel set 7, lower roll 8, motor 9.
Embodiment
Body 1 upper and lower is installed top roll 2 and lower roll 8 respectively, has the film of screening 4 to connect between top roll 2 and the lower roll 8, and the fluted protuberance with video heads 6 in body 1 middle part matches, and motor 9 is installed on the body 1, and top roll 2 or lower roll 8 are connected with motor 9.
Install tensioner wheel set 3 before the top roll 2, tensioner wheel set 7 down is installed before the lower roll 8.
Body 1 is by casing 5 parcels.
Last expansion tightening wheel secondary 3 or following tensioner wheel set 7 are made up of a pair roller.
Hiding film 4 is the scratch resistant PET diaphragm of high printing opacity.
Motor 9 is a micro-step motor.
Top roll 2 or lower roll 8 are connected with motor 9 through reduction gearing.
Top roll 2 or lower roll 8 are that volume has the film 4 of screening on the damping wheel.
The utility model is installed in body 1 on the video observation system; Be about to that the corresponding video heads of body 1 and casing 5 inner groovies 6 is concavo-convex to clamp fixingly, this moment, video heads 6 was in the utility model video observation protective device, and its camera lens can be through hiding film 4 to External Observation; When if the greasy dirt that site environment produces, steam etc. have polluted screening film 4; At this moment can control motor 9 work, be rotated counterclockwise through reduction gearing and let one of top roll 2 or lower roll 8 rotate slowly, contaminated screening film 4 is rolled onto on another top roll 2 or lower roll 8 of correspondence; When the definition that hides film 4 when the part of just in time aiming at video heads 6 reaches observation and requires; Stop motor 9 work, can remain the thin correspondence of part screening film 4PET that just in time to aim at video heads 6 like this and be in clean state, guaranteed the definition of video heads 6 images.
Can hide the consumption of film 4 according to the field condition adjustment; When motor 9 work; Top roll 2 stressed being rotated counterclockwise, owing on 2 of top rolls, damping spring has been installed, top roll 2 will lag behind lower roll 8 in rotation; Remained the rate of tension that hides film 4 between top roll 2 and the lower roll 8 like this, helped observing undistorted.
The effect of last expansion tightening wheel secondary 3 and following tensioner wheel set 7 is the evenness that guarantee to hide film 4.
According to field condition, motor 9 adopts explosion-proof micro-step motor.
According to field condition, wired or wireless control dual mode is adopted in the control of motor 9, like employing line traffic control is arranged, and its control line and video monitoring line are together drawn.
