Description
Technical field
The utility model belongs to a kind of Nitrogen filling system, is specifically related to a kind of dynamic Nitrogen filling system that is suitable for astronomical observation equipment under the condition of polar region.
Background technique
Enclose inside space filling nitrogen to precision type instrument can prevent effectively that as shielding gas instrument and apparatus is oxidized; prolong the working life of precision instrument; it has reliable performance to guarantee precision instrument, and therefore, manufacturer often all can be to these gauge internal space filling nitrogen when dispatching from the factory.
As the ray machine electric system of precision, the astronomical telescope of specialty uses in the place that the temperature difference is arranged or preserves, and steam tends to condense at body surface, if telescope inside can not stop steam to enter, be easy in the lens barrel coagulate frost, not only influence imaging, the time has been grown also can the grievous injury optical element.The telescope protection against the tide in past is to use the dryness storehouse design, siccative is placed in the dryness storehouse the inside, and this type of technology can prevent effectively that telescope inside is subjected to the erosion of moisture, now owing to fill the raising of nitrogen technology, inner general employing of the telescope lens barrel of specialty filled nitrogen technology, effectively waterproof and mildew-resistant.Because South Pole ice dome A is positioned at the cold Antarctic Continent, temperature is at-30 ℃ throughout the year--between 80 ℃, because relative moisture is bigger, the very easy frosting of optical mirror plane is unfavorable for astronomical observation, and this is a difficult problem and emphasis in the South Pole astronomical telescope development of present various countries.Its lens barrel is filled nitrogen can remove steam, prevent the minute surface frosting, guarantee its normal use.
At present to the telescopical nitrogen normally " once-through " that fills, lack a kind of dynamical system fill nitrogen in good time at the nitrogen situation of its lens barrel inside, such nitrogen filling method is practicable under the situation of Attended mode, but because ice dome A area in the South Pole has only the two weeks time human work that suits every year, the most of the time telescope is in the unmanned state, need a kind of dynamic Nitrogen filling system can fill nitrogen as required, drive the steam of lens barrel inside, guarantee the minute surface no frosting, prevent that inner precision type instrument is oxidized, prolong telescopical working life.There is not suitable technological scheme in the prior art.
Summary of the invention
The purpose of this utility model provides a kind of dynamic Nitrogen filling system that is suitable for astronomical observation equipment under the condition of polar region, and this dynamic Nitrogen filling system is used for the precision optics equipment that uses under the condition of the South Pole, particularly is in the astronomical telescope of unmanned state; Nitrogen can fill for a long time in good time in this system, drives the steam of lens barrel inside, guarantees the minute surface no frosting, prevents that inner precision type instrument is oxidized, prolongs telescopical working life.
The technological scheme of finishing the foregoing invention task is, a kind of dynamic Nitrogen filling system that is suitable for astronomical observation equipment under the condition of polar region, on the telescope lens barrel seal closure is housed, it is characterized in that, the sealing cover is connected with nitrogen bottle by solenoid valve, rapid pipe joint and flexible pipe; Described solenoid valve is connected with control system by network.
Such scheme can control electromagnetic valve, adopt nitrogen bottle by rapid pipe joint and the flexible pipe telescope lens barrel inner inflatable to sealed cover sealing.
Solenoid valve is powered to it by power source special.
The utility model has following optimized project:
1, in order to guarantee to fill the nitrogen year, described nitrogen bottle adopts two or more nitrogen bottles to provide nitrogen for the telescope lens barrel jointly, these two nitrogen bottles or a plurality of between also connect with flexible pipe, and insert in the solenoid valve by tee union, guarantee that two gas filling bottles are in state in parallel.
2, described solenoid valve is connected with control system by network, its Placement, and the switch by iridium satellite satellite Remote solenoid valve is adopted in suggestion.
3, load onto the silicone rubber seal pad on the seal closure, the joint connects lens barrel and seal closure, and is screwed to the slight compressive deformation of silicone rubber with the sealing of low temperature glue;
4, between described nitrogen bottle and solenoid valve, also be provided with pressure regulator valve;
5, the joint that can tolerate polar region-80 ℃ low temperature is adopted in described rapid pipe joint.
Specific implementation method of the present utility model is: at first will adorn seal closure on the telescope lens barrel, and with its sealing, use silicone rubber seal between seal closure and telescope lens barrel and the intermediate mass, and be screwed extremely, silicone rubber is out of shape slightly, and guarantee its sealing.
Nitrogen bottle connects solenoid valve by threeway, and solenoid valve is used for controlling the inflationtime of nitrogen, is connected to operable rapid pipe joint under the low temperature on the solenoid valve, and is connected to the lens barrel inner inflatable with the telescope lens barrel by flexible pipe.Solenoid valve is powered to it by power source special.
In actual use, because low temperature lower seal element may go wrong, the utility model is by the switch of iridium satellite satellite Remote solenoid valve, according to actual conditions, certain hour fills nitrogen at interval, makes the air pressure of lens barrel inside remain the air pressure that is slightly larger than the external world, guarantees that the extraneous air that contains moisture does not enter lens barrel inside, to guarantee the drying in the lens barrel, prevent the minute surface frosting.
The beneficial effect of model utility
Nitrogen filling system of the present utility model can satisfy year use more in the unmanned state under the harsh and unforgiving environments of polar region of precise light Mechatronic Systems, prevents the minute surface frosting, and its performance mainly contains following advantage:
1. easy for installation simple, all connections all plug with rapid pipe joint;
2. can protect the precision instrument and equipment in the lens barrel;
3. low temperature resistant, can tolerate the low temperature of polar region-80 ℃;
4. guarantee that lens barrel is inner dry, prevent the minute surface frosting;
5. in light weight, easy to carry;
6. Remote fills nitrogen as required, keeps the nitrogen pressure in the lens barrel.
