Abstract
The utility model provides a gas flow type protective cover, including a dustproof cover, the front end of which is provided with a dust-shield glass. The protective cover is characterized in that a blower motor connected with a wind guide tube is arranged in the dustproof cover, a wind inlet of the blower motor is arranged on the dustproof cover, a wind intake port is arranged on the upper side of the dustshield glass, and the wind guide port is connected with the wind guide tube. The gas flow type protective cover is capable of generating a strong clean gas flow layer along the front surface of the dustproof glass of the protective cover to separate the air containing impurities and dust from the front surface of the dustproof glass, such that the impurities and dust in the air can not be contacted with and accumulated on the front surface of the dustproof glass so as to ensure the dustproof glass to be clean and transparent, and the dustproof glass is free of cleaning for long time.
Description
Technical field
The utility model relates to a kind of air-flowing type protective cover that is used for rig camera, and airborne pollution impurity can't be contacted with the dust-break glass surface of rig camera with dust, belongs to the dust guard technical field.
Background technology
Video camera and camera lens are placed in the protective cover, and purpose is to avoid airborne pollution impurity and dust to corrode camera lens.But can make the image blurring unclear of video camera picked-up as untimely clear wiping protective cover, seriously have influence on monitoring effect.Because it is easier and do not influence original optimum Working such as the aperture focal length of camera lens and focusing than the clear camera lens of wiping to wipe protective cover dust-break pollution impurity on glass and dust clearly.
For creating safe city, the number of cameras of installing on the street increases considerably in recent years.Especially vehicle flowrate cart speed is fast on highway and viaduct, and the pollution impurity that produces in the air and the air-flow of dust are also bigger, and special video camera in the tunnel is in the air-flow that pollutes especially severe all the time.Protective cover dust-break glass is wiped quantity clearly not only to be needed to increase considerably but also wipes number of times clearly and also need to be multiplied, and maintenance workload is increased suddenly, and maintenance cost significantly improves.
Summary of the invention
The purpose of this utility model provides a kind of protective cover that can reduce maintenance workload.
In order to achieve the above object, the technical solution of the utility model has provided a kind of air-flowing type protective cover, comprise dust cover, front end at dust cover is provided with dust-break glass, it is characterized in that the air blast motor that is connected with guide duct is located in the dust cover, has the inlet scoop of air blast motor in dust cover, above dust-break glass air guide hole is arranged, air guide hole links to each other with guide duct.
There is wind deflector the air guide hole front, and wind is moved along the dust-break glass front.
On described inlet scoop, be provided with the impurity absorption device.
Be provided with sky shade on described dust cover, described air blast motor and described wind deflector are located in the sky shade.
The utility model can produce one stronger cleaning gas tream layer along protective cover dust-break glass front, to contain air and the dust-break glass front of polluting impurity and dust isolates, airborne pollution impurity can't be contacted with the dust-break glass front and pile up with dust, thereby guarantee dust-break glass surface clean transparent, reach and avoid the purpose of wiping clearly for a long time.
Description of drawings
The structural representation of a kind of air-flowing type protective cover that Fig. 1 provides for the utility model.
Embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 1, a kind of air-flowing type protective cover that provides for the utility model, comprise dust cover 1, video camera 9 is located in the dust cover 1, front end at dust cover 1 is provided with dust-break glass 2, and the air blast motor 3 that is connected with guide duct 7 is located in the dust cover 1, has the inlet scoop of air blast motor 3 on the back lower place of dust cover 1, be formed with air guide hole 6 by wind deflector 5 above dust-break glass 2, air guide hole 6 links to each other with guide duct 7.On described inlet scoop, be provided with impurity absorption device 4.Be provided with sky shade 8 on described dust cover 1, described air blast motor 3 and described wind deflector 5 are located in the sky shade 8.
Air-flowing type protective cover inside is a seal cavity basically, and an air guide hole 6 is arranged in the upper edge of dust-break glass.Air blast motor 3 produces stronger distinguished and admirable, produces through guide duct 7 and wind deflector 5 dust-break glass 2 surfaces of being sent as an envoy to by air guide hole 6 that one is stronger distinguished and admirable, and guide duct 7 is accomplished seamless link with air guide hole 6.A removable impurity absorption device 4 has been installed on the inlet scoop has been communicated, when air blast motor 3 work, sucked to go out by air guide hole 6 from the inlet scoop with the air in the external world with the external world.Because the effect of impurity absorption device 4, the air-flow that air blast motor 3 produces is a cleaning gas tream, thereby reaches the dust-break glass 2 surfaces clean transparent purpose that avoids wiping clearly all the time.
The wind speed that air blast motor 3 in the utility model produces is bigger, but continuous working simultaneously is more than 20,000 hours.Impurity absorption device 4 is looked environmental pollution degree difference, needs to change once in about 3 months to 6 months.
