Specific embodiment：
Implementation to technical scheme below in conjunction with the accompanying drawings is described in further detail：
As shown in Figures 1 to 3, wind tunnel type camera protection device of the present invention, including base, ventilator cowling 4, blower fan, the video camera mounting shell 5 for disposing video camera 10；Ventilator cowling 4 is fixed on base, and video camera mounting shell 5 is then fixed on the top of ventilator cowling 4；Described video camera mounting shell 5 is dividing wall type tube structure, and the dividing wall type tube structure includes the inner barrel and outer cylinder body of coaxial socket, there is annular gap between the outer wall of inner barrel and the inwall of outer cylinder body；Video camera 10 is lying in dividing wall type tube structure, and described dividing wall type tube structure, mirror lid 7 is connected with 12 adjacent inner barrel end part seals of camera view mouthful, and mirror lid 7 and camera view mouthfuls 12 just to position at be made of transparent material, and the outer cylinder body end adjacent with camera view mouthful 12 is open sets；Ventilator cowling 4 is provided with air inlet and air outlet 11, and assembling is in ventilator cowling 4, and the air inlet of blower fan is connected by the air inlet of ventilator cowling 4 with external environment, and the air outlet of blower fan is connected by the air outlet of ventilator cowling 4 with the partition of dividing wall type tube structure；The wind of external environment blows out after the air inlet of ventilator cowling 4 enters through fan outlet, after flowing through the partition of dividing wall type tube structure, external environment is flowed in the annular gap from 12 adjacent faces of dividing wall type tube structure and camera view mouthful.
Why the present invention takes down the ventilator cowling for being placed in video camera mounting shell, and reason is：
When ventilator cowling it is preposition in video camera mounting shell when, the wind-force of blower fan blowout is not concentrated, no blast, it is necessary to separately set air channel, meanwhile, such structure type needs video camera producer to be designed, and not so can influence camera field；
When video camera mounting shell is placed in after ventilator cowling, have the drawback that video camera mounting shell rear end must reserve blower fan breathing space, overall weight is overweight, more than the enabling capabilities of head；
Therefore, after the present invention considers, underneath type ventilator cowling is just have chosen, is concentrated with air quantity, blast is suitable, overall weight is also adapted for head support, meanwhile, it is also relatively simple in manufacture craft.
In addition, the present invention selection cylinder dividing wall type tube structure, reason be cylindrical structural wind pressure resistance for other structures, it is much smaller.
Ventilator cowling of the present invention 4 has two air inlets, is arranged symmetrically in the both sides of ventilator cowling 4；And the air inlet of each ventilator cowling 4 is fitted with into air duct 14；Described to enter that air duct 14 is L-shaped, with the flat segments and vertical section that on the corner connect, the end of flat segments is connected with ventilator cowling 4, and the end of vertical section is down-set；Even if in sleety weather, by the transition of vertical section, the air-flow into ventilator cowling 4 can also reduce moisture.
Sealed by dust-proof seal ring 9 between mirror lid 7 of the present invention and the end of inner barrel, it is to avoid dust enters in video camera mounting shell 5, dirty camera lens.
The equipped sight glass 15 of the medium position of mirror lid 7 of the present invention；The mouth of finding a view of video camera is oppositely arranged with sight glass 15.
Dividing wall type tube structure of the present invention, the other end being oppositely arranged with mirror lid 7 is removably sealed and installed with cover plate 6, is easy to be put into video camera in video camera mounting shell 5；Meanwhile, the mode installed is sealed, can prevent dust from entering video camera mounting shell 5.
Blower fan of the present invention is axial fan, and water proof type blower fan is pressed in specifically DC-24V, and the axial flow direction of the blower fan is perpendicular with the axis direction of camera view mouthful 12.
Base of the present invention is head bearing, including head base 1, head main body 2 and head horizontal base 3；Head main body 2 is arranged on head base 1, and head main body 2 is connected by head horizontal base 3 with blower fan such that it is able to adjust the shooting ken of video camera.
The annular gap existed between inner barrel outer wall of the present invention and outer cylinder body inwall is 1-2mm.
In addition, being fitted with rain cover eaves 8 with the upside of 12 adjacent outer cylinder body ends of camera view mouthful, prevent sleet from falling on mirror lid 7.
Operation principle：
Air-flow enters interior outer shield gap by mozzle after blower fan work, sealed using bonnet at outer shield rear portion, according to air flow principle, forced draft is forward by the partition of video camera installation shell, and contacts glass of finding a view in the anterior air blast obstruct sleet that moves ahead that formed of video camera.Solenoid-operated switch is installed additional in camera control circuit board 13, control axial flow blower power supply, reach the purpose that blower fan is controlled by network.
Technological means disclosed in the present invention program is not limited only to the technological means disclosed in above-mentioned technological means, also including being combined constituted technical scheme by above technical characteristic.
With above-mentioned according to desirable embodiment of the invention as enlightenment, by above-mentioned description, relevant staff can carry out various changes and amendments without departing from the scope of the technological thought of the present invention' completely.The technical scope of this invention is not limited to the content on specification, it is necessary to its technical scope is determined according to right.
