Description
Technical field
This utility model belongs to security protection video monitoring field, especially a kind of shield for preventing form fogging.
Background technology
At present, in security protection video monitoring field, with the change of the market demand, the sealing property requirement to shield is more next
It is higher, the either shield of common protective cover, spherical protecting cover or head standard configuration, it is desirable to which water resistance is IP66, IP67.
The form fogging of shield belongs to natural phenomena, the reason for form fogging is：Shield is internal in production assembling process
The air of retention has the parts such as the video camera of installation, circuit board, camera lens, motor in certain humidity, shield, all-weather protection
Cover is applied in various environment, and components and parts produce heat at work, cause shield internal and external temperature, pressure to have differences, are regarding
The inner surface of window condenses into water smoke, has a strong impact on the video monitoring effect of video camera, visible ray, thermal imaging.
Traditional employing electronics demister, does not only take up larger space in shield, and centering small guard cover is relatively not suitable for,
And processing cost is higher.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of shield for preventing form fogging.
What scheme of the present utility model was realized in：
A kind of shield for preventing form fogging, including base, shell and upper lid, the sealed bottom of the shell installs bottom
Plate, the arranged on left and right sides of the base plate are symmetrically installed the first waterproof vent valve, and the base plate is arranged on base, the top sealing of shell
Lid is installed, the second waterproof vent valve is installed in centre of lid on this, the anterior of the shell installs form, the bottom of the inside the shell
The bracing frame of fixed video camera is installed on plate, top board is installed at the top of the bracing frame, between two the first waterproof vent valves
The first fan is installed in the bracing frame bottom of top, installs the second fan on the top board below the second waterproof vent valve of correspondence.
And, sealing ring is installed between the upper lid and shell.
And, video camera fixed plate is installed on the bracing frame above first fan.
And, first waterproof vent valve and the second waterproof vent valve are screw-type waterproof vent valve, model
VV-PFVM16051-B30。
And, the shell is the conical shell structure stood upside down.
And, support frame as described above is U-shape structure.
Advantage of the present utility model and good effect are：
1st, this patent passes through the first waterproof vent valve and the cooperation of the first fan is drawn air in shield, the second waterproof and breathable
Valve and the second fan coordinate discharges the air in shield, so as to realize the convection current of shield inner air.This utility model is utilized
Hot-air in Aerodynamics rises, the principle that cold air sinks, and on the premise of water resistance is ensured, makes shield
Inside and outside air is swapped, and so as to the hot-air in shield is discharged, solves the problems, such as fogging in sealing protection cover, it is ensured that
The definition of camera review.
2nd, it is additionally, this utility model simple structure, easy to process, it is easy to dismount, cheap and easy to maintenance.
Description of the drawings
Fig. 1 is front view of the present utility model；
Fig. 2 is the sectional view of Fig. 1.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings and by specific embodiment.
A kind of shield for preventing form fogging, as shown in Figure 1 and Figure 2, including base 7, shell 3 and upper lid 1, the shell
For the conical shell for standing upside down, its sealed bottom mounting base 5, the arranged on left and right sides of the base plate are symmetrically installed the first waterproof vent valve
6, the base plate is arranged on base, and lid is installed in the top sealing of shell, and on this, the second waterproof and breathable is installed in the centre of lid
Valve 2, the anterior of the shell install form 4, install the U-shape structure of fixed video camera (not shown) on the base plate of the inside the shell
Bracing frame 13, the top of the bracing frame installs top board 9, the bracing frame bottom of top between two the first waterproof vent valves
First fan 15 is installed, the second fan 8 is installed on the top board below the second waterproof vent valve of correspondence.
In the present embodiment, it is described it is upper lid and shell between install sealing ring 10, it is ensured that shield sealing, on this lid with
Shell is solidly installed using the connection of screw 11.
Video camera fixed plate 14 is installed on the bracing frame above first fan.
First waterproof vent valve and the second waterproof vent valve are screw-type waterproof vent valve, and the vent valve is double
To ventilative, model VV-PFVM16051-B30.
Operation principle of the present utility model is：
First waterproof vent valve and the first fan coordinate and draw air in shield, the second waterproof vent valve and the second fan
Coordinate and the air in shield is discharged, so as to realize the convection current of shield inner air, Fig. 2 plants flowing side of the direction of arrow for air-flow
To.This utility model is risen using the hot-air in Aerodynamics, the principle that cold air sinks, and is ensureing water resistance
On the premise of, swap the inside and outside air of shield, so as to the hot-air in shield is discharged, solve in sealing protection cover
The problem of fogging, it is ensured that the definition of camera review.
It is emphasized that embodiment described in the utility model is illustrative, rather than it is determinate, therefore this reality
It is with new including the embodiment being not limited to described in specific embodiment, every new according to this practicality by those skilled in the art
The other embodiment that the technical scheme of type draws, also belongs to the scope of this utility model protection.
