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 is used aboard specially; conventionally can be placed in a bin relatively sealing; because aircraft is in flight course; can switch different height above sea levels; cause bin internal gas pressure different; this,, with regard to needing the air in bin to take a breath, 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 be to outside exhaust, 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, at this moment just brings a problem, and the steam in extraneous air can enter in camera, affects the service life of camera.
Traditional settling mode is to use drier, and in the situation that 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, thereby instrument is produced to harmful effect.
Summary of the invention
For overcoming above-mentioned deficiency, the object of the invention is to provide a kind of dry bar that enters the moisture content in aviation measuring camera in air that reduces.
The solution of the present invention is as follows: a kind of aviation measuring camera dry bar, comprise body, and described body two end openings, middle part hollow out, described body one end arranges the sealing-plug sealing with passage, and the other end arranges the nut sealing with passage; In body, place drier and stainless steel microballoon, described drier and stainless steel microballoon are 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 the trapezoidal length of going to the bottom is greater than square length, and passage runs through sealing-plug.
Further, described nut appearance is worn external screw thread.
Beneficial effect of the present invention:
1, simple in structure, easy to assembly, by the filter cotton that arranges, to preparing to enter airborne steam in camera, to carry out first dry, then run into stainless steel microballoon and start to condense into the globule, reduce steam inlet, also be convenient to the dry in time of drier, the gas that makes to enter in camera keeps dry simultaneously, extends camera service life.
2,, by transparent barred body and changeable colour drier, the service condition that can observe in time barred body internal desiccant, when reaching dry saturation state, the drier in timely dry bar or dry bar.
3, the present invention also realizes and deposits the bin of camera and the air exchange outside storehouse, so that 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.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
An aviation measuring camera dry bar, comprises body 1, described body 1 two end openings, and middle part hollow out, described body 1 one end arranges sealing-plug 2 sealings with passage I 8, and the other end arranges nut 3 sealings with passage II 9; In body, place drier 4 and stainless steel microballoon 5, described drier 4 and stainless steel microballoon 5 are 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 portions are trapezoidal, back segment is square, and the trapezoidal length of going to the bottom is greater than square length.
The present invention can carry out screw thread with the bin of placing aviation measuring camera by the external screw thread on nut and fix.
When aircraft rises, the air pressure of bin is greater than the air pressure outside storehouse, air in bin is discharged air by the present invention, first air discharges by the passage I 8 of sealing-plug 2, then pass through filter pulp I 6 impurity screenings, successively by each section, finally by the passage II 9 on nut 3, discharge outside bin again.
When aircraft declines, the air pressure of bin is less than the air pressure outside storehouse, and the air outside bin need to enter in bin, first by passage II 9, enters, run into filter cotton II 7 and carry out first adsorption filtration, then run into drier 4 and stainless steel microballoon 5, drier 4 is dried, and stainless steel microballoon 5 becomes the globule by the condensation vapor running into, reduce on the one hand steam inlet, on the other hand, delay steam admission velocity, be dried 4 to the drier time more and process.Then by filter cotton I 6, carry out again dry filter again, finally by passage I 8, entered in bin.
By above-mentioned dry, filtration, the vapour quantity entering in camera is reduced in a large number, has guaranteed 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 above the specific embodiment of the present invention has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned embodiment according to conception of the present invention and change and revise; when its function producing does not exceed spiritual that description contains yet, all should be within protection scope of the present invention.
