Description
Technical field
The utility model relates to a kind of heat-proof devices, and specifically the video camera air curtain for the test of thermal environment occasion is heat-insulated
Device.
Background technique
It is well known that in much test occasions requiring that video camera is used to observe test objective in real time as monitoring device
The state of object.However, many tests are carried out under higher or lower temperature environment, when testing ground environment temperature is super
When the high/low temperature limit that video camera can bear out, the service life of video camera just will affect, or even directly contribute video camera
Damage.
Generally under cryogenic, it can use and protective shell is set outside video camera, and place heating in protective shell
Band completely cuts off influence of the low temperature environment to video camera using the heating of heating tape.And when environment temperature is high temperature, it is just difficult to solve
The certainly protection question of video camera.It will be video camera reduced service life because of high temperature such as by video camera in test site
Or damage.Such as by video camera outside the test site, will lead to the problem of that visual angle is small can not comprehensive observation
Utility model content
Problem to be solved in the utility model is to provide a kind of video camera air curtain heat-proof device, which being capable of isolated environment
Influence of the heat to video camera will not influence the service life or damage video camera of video camera, it can be ensured that video camera is in high temperature
It is operated normally under experimental enviroment.
To solve the above problems, taking following technical scheme:
The characteristics of video camera air curtain heat-proof device of the utility model be include gas gathering mask, the upper end closed of the gas gathering mask and
There is the mounting hole for installing video camera, in open state and there is inside flanging in the lower end of gas gathering mask.The side wall of the gas gathering mask
There is air pipe interface.
Wherein, the top of the gas gathering mask is conus portion, and the lesser one end of its diameter is located at upper end, described for installing
The mounting hole of video camera is located on the end of conus portion, and the air pipe interface is located at the lower end side of conus portion.The gas gathering mask
Lower part be cylindrical portion, the upper end and conus portion are in integrally connected, and the inside flanging is located at the lower end of cylindrical portion.
Further improvement of the utility model scheme is that the interior edge of the flanging is evenly equipped with limit chafing mat, limits chafing mat
Upper end be above flanging.Preferably, the limit chafing mat is made of silica gel.
Above scheme is taken, is had the advantage that
The video camera air curtain heat-proof device of the utility model includes gas gathering mask, the upper end closed of the gas gathering mask and is had for pacifying
The mounting hole of video camera is filled, in open state and there is inside flanging in the lower end of gas gathering mask；The side wall of gas gathering mask has air pipe interface.Make
The connection bolt of monitoring camera upper end is fixed on the mounting hole of gas gathering mask upper end by the used time by nut, then will pressure
Contracting air has air pipe interface to imported into gas gathering mask by extension tube attached, so that it may form an air curtain in the periphery of video camera, have
Influence of the barrier ambient enviroment especially hot environment of effect to video camera, can prevent the damage of video camera, extend it and use the longevity
Life.Under hot test environment, the normal operation of video camera can also ensure that, guarantee that the real-time observation to test objective object is supervised
Control.
Further, it can not only be limited in the mounted state in the flanging along the limit chafing mat being uniformly arranged
Spacing, position between camera masking and gas gathering mask flanging, additionally it is possible to prevent camera lens and flanging from friction damage occurs
Camera lens.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the video camera air curtain heat-proof device of the utility model；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is the use state diagram of the video camera air curtain heat-proof device of the utility model.
Specific embodiment
The utility model is described in further details below in conjunction with attached drawing.
As depicted in figs. 1 and 2, the video camera air curtain heat-proof device of the utility model includes gas gathering mask 1, the gas gathering mask 1
Upper end closed and there is mounting hole 2 for installing video camera 6, in open state and there is inside flanging 4 in the lower end of gas gathering mask 1.Institute
The side wall for stating gas gathering mask 1 has air pipe interface 3.In the present embodiment, the top of the gas gathering mask 1 is conus portion, and its diameter is smaller
One end be located at upper end, the mounting hole 2 for installing video camera 6 is located at the end of conus portion, the air pipe interface 3
In the lower end side of conus portion.The lower part of the gas gathering mask 1 is cylindrical portion, and the upper end and conus portion are in integrally connected, it is described to
Interior flanging 4 is located at the lower end of cylindrical portion.
In order in a state of use, limit the spacing between 6 lens case 9 of video camera and 1 flanging 4 of gas gathering mask, position, while really
Friction damage will not be occurred with flanging 4 by protecting 6 camera lens of video camera, and the present embodiment is also evenly arranged limited on the interior edge of the flanging 4
The upper end of position chafing mat 5, limit chafing mat 5 is above flanging 4.Preferably, the limit chafing mat 5 is made of silica gel.
In use, as shown in figure 3, the bolt fixing end 7 of monitor camera 6 is passed through taking the photograph for the utility model from bottom to top
The mounting hole 2 of camera air curtain heat-proof device gas gathering mask 1, and bolt fixing end 7 is locked from outside with nut 8.Then, sharp
It is connected with external tracheae with the air pipe interface 3 of gas gathering mask 1, compressed air is imported between 1 inner wall of gas gathering mask and video camera 6, so that it may
To form the air curtain of a room temperature in 6 surrounding of video camera.It is anti-friction due to limiting between 1 flanging 4 of 6 lens case 9 of video camera and gas gathering mask
The effect of pad 5 and form a ring gap, which is then used as the outlet of air curtain.The air curtain can not only separate video camera 6
Contact with hot-air, while certain cooling down can also be played the role of to video camera 6.
