Description
Technical field
The present invention relates to a kind of Water-proof exhausting aerial camera structure, can be widely applied to store working environment moistening, air pressure
In the aerial camera field for changing at any time.
Background technology
In aerial camera field, ground-mounted environment moistening, aerial camera working environment typically often experiences extraneous ring
Border normal barometric pressure --- low pressure --- normal barometric pressure changes working environment, while it is very big also to run into humidity in flight course
Process；And often ground storage time is longer for aerial camera, storage condition is harsh during storage, cost intensive.Mirror
Optical element inside head (general humidity more than 60%) in the environment of moistening easily produces mildew, causes optical element to pass through
Rate declines, and reduces camera lens performance；Prevent external moisture from entering according to sealing camera lens, hypobaric causes the interior of camera lens
Outside draught head can cause the type change of optical element face, ultimately result in optical lens hydraulic performance decline, it is therefore desirable to by camera lens
The gas in portion is discharged, and realizes camera lens inside and outside air pressure balance.And at present on the market waterproof membrane can only typically prevent humidity 90%
Steam above passes through, it is therefore desirable to designs a kind of Water-proof exhausting aerial camera structure and can solve the problem that camera assembling, working environment
Inner and outer air pressure it is poor, while eliminate camera lens internal steam, prevent with steam during extraneous exchanging gas enter camera lens problem.
The content of the invention
The present invention provides a kind of Water-proof exhausting aerial camera structure, is prevented from external moisture and enters inside aerial camera,
Also can quickly realize optical mechanical system inside and outside air pressure balance simultaneously.
Technical scheme is as follows：
The Water-proof exhausting aerial camera structure, including camera lens, electric cabinet and the detector that is installed on inside electric cabinet；It is described
Camera lens is arranged on the forward chamber of electric cabinet by screw, and the big end of camera lens is protruded from the front end of electric cabinet, forms the half of camera lens
Sealing structure；Camera lens be located at the forward chamber in part offer steam vent on the wall of lens barrel side so that camera lens inside with
The forward chamber UNICOM；The side wall of the forward chamber is provided with Water-proof exhausting valve, and Water-proof exhausting valve inside is filled with drying
Agent, by the Water-proof exhausting valve forward chamber and extraneous air UNICOM are realized.
On the basis of above scheme, the present invention has also further made following optimization：
The concrete structure of above-mentioned Water-proof exhausting valve can be：Including valve body, valve gap and desiccant, the both ends open of valve body,
Wherein big end is located at outside electric cabinet, and small end is located at the heavy platform groove of the interior of the forward chamber of electric cabinet, big end and small end
On be respectively provided with one layer of waterproof membrane, desiccant is filled between this two-layer waterproof membrane, and valve gap compresses the waterproof membrane at the big end of valve body
And cover the big end of valve body.
In order to have more reliable installation and sealing effect, external screw thread can be respectively provided with the big end of valve body and small end, greatly
End screw thread to valve gap Matching installation, small end screw thread to electric cabinet Matching installation.
The sealing means of the rear and front end of above-mentioned camera lens can be:The rear and front end of camera lens is compressed by trim ring seal respectively
The sealing of camera lens rear and front end is realized in circle deformation on lens barrel and corresponding lens contact surface.
The small end of above-mentioned camera lens and the junction of electric cabinet, namely sealing ring is may also set up between camera lens and detector, lead to
Cross the sealing that on the detector sealed ring deformation is realized between camera lens and detector of camera lens pressure.
The invention has the beneficial effects as follows：
1st, the air inside the camera lens of semitight by steam vent, through waterproof arrange with camera (electric cabinet) by internal air
Air valve is exchanged with the external world, quick to realize and extraneous air pressure balance, the wet air in the external world after Water-proof exhausting valve, in air
Big steam group stopped outside by Water-proof exhausting valve, little steam is rolled into a ball and absorbed by the desiccant in Water-proof exhausting valve, so as to ensure into
It is dry air to enter to camera internal.
2nd, sealing ring is set between camera lens rear end and detector, is prevented effectively from outside fifth wheel into camera lens rear end and detection
Between device, prevent fifth wheel adhesion detector from affecting imaging function.
3rd, version is simple, with low cost.
4th, Water-proof exhausting structure is without additional complexity mechanism is increased, upon storage between it is longer when, the compartment time changes waterproof row
Air valve.
5th, can quickly realize optical lens inside and outside air pressure balance automatically, it is ensured that working condition it is constant.

Specific embodiment
The embodiment that the present invention is provided is described below in conjunction with accompanying drawing：
As shown in figure 1, the Water-proof exhausting aerial camera is mainly made up of camera lens, Water-proof exhausting valve, sealing ring and electric cabinet.
As shown in Fig. 2 deformed on lens barrel and the contact surface of mirror one using the first trim ring pressure seal ring one respectively, the second trim ring
Pressure seal ring two deforms the sealing for realizing camera lens front and back end on lens barrel and the contact surface of mirror two；
Camera lens is arranged on electric cabinet by bolt, and the sealing ring of appropriate size is set between camera lens and detector,
By the sealing that on the detector sealed ring deformation is realized between camera lens and detector of camera lens pressure.Can effectively prevent camera test,
Steam and fifth wheel problem in transport, storage, working environment.
As shown in Figure 3-Figure 5, one layer of waterproof membrane is placed in Water-proof exhausting valve body small end, waterproof membrane can filter humidity and be more than
90% steam, then some desiccant particles are placed, then in desiccant upper end, one layer of waterproof membrane is placed on the heavy platform groove of valve body,
Compressed with valve gap again.It is arranged on electric cabinet finally by matching thread.
Because the water absorbing capacity of desiccant is limited, in the case where Storage period is longer, can more for some Water-proof exhausting valves,
At ordinary times by its with adhesive tape etc. by its valve body small end and valve bonnet seal, take adhesive tape when using off.The compartment time changes waterproof row
Air valve can effectively accomplish the function of Water-proof exhausting.
Operating mode：In the daily storing process of camera, the air of camera lens and camera internal and the external world swap, extraneous and internal
The unique flow passage of air is：--- --- camera internal --- Water-proof exhausting valve --- is extraneous for steam vent inside camera lens.Therefore
Humid air turnover camera internal all can be through Water-proof exhausting valve so as to by the desiccant absorption steam in valve body, it is ensured that camera and mirror
Drying inside head.Simultaneously the larger steam of humidity is directly stopped outside by waterproof membrane, it is ensured that the effective life of desiccant,
Simultaneously two-layer waterproof membrane also enters camera internal with the desiccant dust that can prevent extraneous fifth wheel and in valve body in valve body, causes
Fifth wheel pollutes.The camera smoothly carries out gas exchange, it is ensured that with the external world outside the protection for ensureing steam and fifth wheel with the external world
Draught head.
