The surfacing wiping ball is different, therefore in friction process, friction ball carries enough electrostatic charges, and electrostatic charge is transferred to electrostatic
The surface of pin；According to point discharge phenomenon, when the end of electrostatic pin accumulates enough electric charges, point discharge will occur, tip is put
Electricity moment punctures air, and produces bigger heat so that air expansion；Therefore, under the rubbing action that frictional disk is lasting, electrostatic
Electric discharge phenomena are constantly had to occur on pin；Therefore, the air prolonged expansion in electrostatic cavity, air pressure gradually rises；In electrostatic cavity
Air pressure when reaching marginal value, pressure valve is opened, and is sprayed from airway by air；The table of the gas impact camera lens of ejection at a high speed
Face, removes the dust on camera lens surface.
After air ejection in electrostatic cavity, the air pressure in electrostatic cavity reduces, and pressure valve is recovered to close；Sky in electrostatic cavity
After gas is thin, the hot-air in housing enters electrostatic cavity from breather cheek valve；Now, a cycle is completed；
To sum up, in each cycle, electrostatic cavity is by the hot-air sucking-off in housing, and produces high velocity air winding-up camera lens, to mirror
Head is cleaned；Both having served the effect of lens cleaning, and served again the effect of cooling, meanwhile, this inventive structure is simple,
Easy to operate, maintenance cost is cheap.
As preferably, being pasted with concentric drag ring on the disc of described frictional disk, drag ring is by rubber or fur material
Material is made, and the material of adjacent drag ring is different；So that making adjacent electrostatic pin carry different electrostatic charges, promote electric discharge.
As preferably, the spacing between adjacent electrostatic pin is 2-3mm；So that raising discharge effect.
As preferably, the inside of described friction ball is embedded with ferromagnetic pearl, and the inside of described frictional disk is embedded with permanent magnetism sheet；This structure
Magneticaction can be passed through so that friction ball preferably contacts with frictional disk, promote the generation of electrostatic.

Fig. 2 is the structure for amplifying schematic diagram of embodiment illustrated in fig. 1 middle friction tray.
Detailed description of the invention
Embodiment
In the embodiment shown in Fig. 1, Fig. 2, this electrostatic watch-dog includes housing 1 and support 11, and described support 11 is solid
Dingan County is contained in the lower section of housing 1；
Be internally provided with airtight electrostatic cavity 2 at described housing 1, described electrostatic cavity 2 be provided with airway 21, described in lead
The exhaust end of trachea 21 extends the surface of camera lens；Being also equipped with pressure valve 3 in described electrostatic cavity 2, described pressure valve 3 connects quiet
Electricity chamber 2 and airway 21；One-way exhaust valve 211 is installed in airway 21, described electrostatic cavity 2 is provided with one-way air inlet
Valve 4；
Internally installed at described electrostatic cavity 2 has fixed plate 5, and in described fixed plate 5, array is placed with electrostatic pin 6, adjacent quiet
Spacing between acusector 6 is 2-3mm, and this distance can promote electric discharge, is unlikely to make electrostatic pin 6 arrange overstocked simultaneously；Each described quiet
The upper end of acusector 6 is fixed with friction ball 61；The inside of described friction ball 61 is embedded with ferromagnetic pearl；
Driving fan 7 is installed in the outside of described housing 1, drives the drive shaft 71 of fan 7 to stretch into electrostatic cavity 2 internal, drive described
The end of moving axis 71 is provided with frictional disk 8；The inside of described frictional disk 8 is embedded with permanent magnetism sheet；Described frictional disk 8 and friction ball 61 phase
Contact；
Described frictional disk 8 uses rubber and fur material to make with the surface of friction ball 61, and frictional disk 8 connects with friction ball 61
The surfacing touched is different, i.e. the elastomeric material part of frictional disk 8 and the fur material part contact of friction ball 61, frictional disk 8
The elastomeric material part contact of fur material part and friction ball 61；
In the present embodiment, on the disc that described frictional disk 8 contacts with friction ball 61, it is pasted with concentric drag ring 81, rubs
Wipe ring 81 to be made by rubber or fur material, and the material of adjacent drag ring 81 is different, i.e. rubber ring is staggered with fur ring；
Therefore, the electrostatic pin 6 of adjacent drag ring 81 correspondence, in friction process, produce contrary electrostatic charge, this structure can promote point
End electric discharge.
Watch-dog is arranged on outdoor, and the watch-dog particularly used in traffic system, photographic head is placed in the two of road more
Other；The wind-force of these positions is relatively big, and under the blowing of high velocity air, described driving fans 7 drive drive shaft 71 synchronous axial system, enters
And drive frictional disk 8 synchronous axial system；Under magneticaction, frictional disk 8 keeps contacting closely with friction ball 61 all the time, owing to rubbing
Wiping dish 8 is different from the surfacing of friction ball 61, therefore in friction process, friction ball 61 produces enough electrostatic charges, quiet
Charge transfer is to the surface of electrostatic pin 6；According to point discharge phenomenon, when the end of electrostatic pin 6 accumulates enough electric charges, will occur
Point discharge, point discharge moment punctures air, and produces bigger heat so that air expansion；In the present embodiment, adjacent rub
Wiping the electrostatic pin 6 of ring 81 correspondence, in friction process, produce contrary electrostatic charge, this structure can promote point discharge；Cause
This, under the rubbing action that frictional disk 8 is lasting, electrostatic pin 6 constantly has electric discharge phenomena occur；Therefore, the sky in electrostatic cavity 2
Gas prolonged expansion, air pressure gradually rises；When air pressure in electrostatic cavity 2 reaches marginal value, pressure valve 3 is opened, and by air from
Airway 21 sprays；The surface of the gas impact camera lens of ejection, removes the dust on camera lens surface at a high speed.
After air ejection in electrostatic cavity 2, the air pressure in electrostatic cavity 2 reduces, and pressure valve 3 is recovered to close；In electrostatic cavity 2
Rarefaction of air after, the hot-air in housing 1 enters electrostatic cavity 2 from breather cheek valve 4；Now, a cycle is completed；To sum up,
In each cycle, electrostatic cavity 2 is by the hot-air sucking-off in housing 1, and produces high velocity air winding-up camera lens, carries out camera lens clearly
Clean；Both having served the effect of lens cleaning, and served again the effect of cooling, meanwhile, this inventive structure is simple, operation side
Just, maintenance cost is cheap.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all spirit in the present invention and
Within principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
