Abstract
The invention discloses a drying stick for an aerial camera. The drying stick comprises a body, wherein two ends of the body are open, and the middle is hollowed-out; a sealing plug provided with a hole is arranged at one end of the body for sealing, and a nut provided with holes is arranged at the other end for sealing; drying agents and stainless steel microspheres are placed in the body and arranged evenly. The drying stick is simple in structure and convenient to assemble, moisture in the air is condensed through the stainless steel microspheres, so that the drying purpose is achieved, the quantity of the moisture entering thecamera is less, and the service life of thecamera is prolonged.
Description
Technical field
The present invention relates to a kind of dry bar, be specifically related to a kind of aviation measuring camera dry bar.
Background technology
A kind of mm professional camera special that aviation measuring camera uses aboard specially; usually can be placed in the bin of an opposing seal; because aircraft is in flight course; different height above sea levels can be switched; cause bin internal gas pressure different; this takes a breath with regard to needing the air in bin, reaches air pressure balance, in order to avoid damage camera.When aircraft flies to high-altitude by low latitude, the air pressure in bin is greater than external pressure, and bin can externally be vented, to reach air pressure balance; When aircraft flies to low latitude by high-altitude, the air pressure in bin is less than external pressure, and outside air can enter bin, and at this moment just bring a problem, the steam in extraneous air can enter in camera, affects the service life of camera.
Traditional settling mode uses drier, and when only using drier, when air inflow is large, in air, steam can not be completely absorbed, and still has a large amount of steam and enters in instrument, thus produce harmful effect to instrument.
Summary of the invention
For overcoming above-mentioned deficiency, the object of the invention is to provide a kind of dry bar reducing in air the moisture content entered in aviation measuring camera.
The solution of the present invention is as follows: a kind of aviation measuring camera dry bar, comprises body, described body two end opening, middle part hollow out, and described body one end arranges the sealing-plug sealing of band passage, and the other end arranges the screw cap closures of band passage; Place drier and stainless steel microballoon in body, described drier and stainless steel microballoon evenly distributed.
Further, between described sealing-plug and drier, filter cotton is set.
Further, between described nut and drier, filter cotton is set.
Further, described body is glass tube.
Further, described drier is changeable colour drier.
Further, described sealing-plug leading portion is trapezoidal, and back segment is square, and trapezoidal length of going to the bottom is greater than square length, and passage runs through sealing-plug.
Further, described nut appearance wears external screw thread.
Beneficial effect of the present invention:
1, structure is simple, easy to assembly, first drying is carried out to preparing the steam entered in the air in camera by the filter cotton arranged, then run into stainless steel microballoon to start to condense into the globule, reduce steam inlet, also be convenient to the timely drying of drier simultaneously, the gas entered in camera is kept dry, extend camera service life.
2, by transparent barred body and changeable colour drier, the service condition of barred body internal desiccant can being observed in time, when reaching dry saturation state, the drier in timely dry bar or dry bar.
3, the present invention also realizes depositing the air exchange outside the bin of camera and storehouse, to make bin and storehouse external pressure balance, extends camera service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the side schematic view of sealing-plug.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
A kind of aviation measuring camera dry bar, comprises body 1, described body 1 two end opening, middle part hollow out, and the sealing-plug 2 that described body 1 one end arranges band passage I 8 seals, and the nut 3 that the other end arranges band passage II 9 seals; Place drier 4 and stainless steel microballoon 5 in body, described drier 4 and stainless steel microballoon 5 evenly distributed.
Between described sealing-plug 2 and drier 4, filter cotton I 6 is set, between described nut 3 and drier 4, filter cotton II 7 is set, described body 1 is glass tube, described drier 4 is changeable colour drier, described sealing-plug 2 leading portion is trapezoidal, back segment is square, and trapezoidal length of going to the bottom is greater than square length.
The present invention carries out screw thread by the external screw thread on nut with the bin placing aviation measuring camera and fixes.
When aircraft rises, the air pressure of bin is greater than the air pressure outside storehouse, air in bin discharges air by the present invention, first air is discharged by the passage I 8 of sealing-plug 2, then through filter pulp I 6 impurity screening, again successively by each section, discharge outside bin finally by the passage II 9 on nut 3.
When aircraft declines, the air pressure of bin is less than the air pressure outside storehouse, and the air outside bin needs to enter in bin, is first entered by passage II 9, run into filter cotton II 7 and carry out first adsorption filtration, then run into drier 4 and stainless steel microballoon 5, drier 4 carries out drying, and the condensation vapor run into is become the globule by stainless steel microballoon 5, reduce steam inlet on the one hand, on the other hand, delay steam admission velocity, carry out drying 4 to the drier time more and process.Then carry out dry filter again by filter cotton I 6 again, finally entered in bin by passage I 8.
By above-mentioned drying, filtration, the vapour quantity entered in camera is reduced in a large number, ensure that the service life of camera.By glass tube body, the variable color program of the machine that can see drying at any time, with as required, changes dry bar or drier at any time.
Although give detailed description and explanation to the specific embodiment of the present invention above; but what should indicate is; we can carry out various equivalence according to conception of the present invention to above-mentioned embodiment and change and amendment; its function produced do not exceed that description contains yet spiritual time, all should within protection scope of the present invention.
