Abstract
The invention provides a dynamic nitrogen charging system of astronomical observation equipment applicable to polar region conditions. A seal cover is arranged on a telescope lens barrel. The dynamic nitrogen charging system is characterized in that the seal cover is connected with a nitrogen cylinder by a quick coupling, a hose and an electromagnetic valve; and the electromagnetic valve is connected with a control system by a network. According to the optimized scheme, two or more nitrogen cylinders are adopted to commonly provide nitrogen gas for the telescope lens barrel, and the two or more nitrogen cylinders are also connected by hoses, and connected into the electromagnetic valve through a three-way connector so as to ensure that two charging cylinders are connected in parallel. A switch of the electromagnetic valve is controlled remotely by adopting an iridium satellite. The nitrogen charging system can meet the requirement that a precise opto-electro-mechanical system can be used in severe polar environment in a hibernating manner under unmanned state, prevents the frost formation on a mirror surface, is convenient and simple to install, and can protect precise instrument in the telescopic barrel.
Description
Technical field
The invention belongs to a kind of Nitrogen filling system, be specifically related to a kind of dynamic Nitrogen filling system that is applicable to close astronomical observation equipment under the condition of polar region.
Background technique
To the enclose inside space filling nitrogen of precision type instrument, as shielding gas, can effectively prevent that instrument and apparatus is oxidized; extend the working life of precision instrument; it has reliable performance to guarantee precision instrument, and therefore, while dispatching from the factory, manufacturer often all can be to these gauge internal space filling nitrogen.
As accurate Light Electrical system, the astronomical telescope of specialty uses or preserves in the place that has the temperature difference, and steam tends to condense at body surface, if telescope inside can not stop steam to enter, in lens barrel, be easy to solidifying frost, not only affect imaging, the time has been grown also can grievous injury optical element.The telescope protection against the tide in past is to use dryness storehouse design, siccative is placed in dryness storehouse the inside, and this type of technique can effectively prevent that telescope inside is subject to the erosion of moisture, now owing to filling the raising of nitrogen technology, inner general employing of lens cone for telescope of specialty filled nitrogen technique, effectively waterproof and mildew-resistant.Due to the South Pole, ice dome A is positioned at the cold Antarctic Continent, and temperature is at-30 ℃ throughout the year--and between 80 ℃, because relative moisture is larger, 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 current various countries.Its lens barrel is filled to nitrogen and can remove steam, prevent minute surface frosting, guarantee that it normally uses.
At present to the telescopical nitrogen normally " once-through " that fills, lack a kind of dynamical system and fill nitrogen for the nitrogen situation of its lens barrel inside in good time, such nitrogen filling method is practicable in the situation that of Attended mode, but because ice dome A area, the South Pole only has suitable human work of two weeks time every year, most of the time telescope is in unmanned state, need a kind of dynamic Nitrogen filling system can fill as required nitrogen, drive the steam of lens barrel inside, guarantee minute surface no frosting, prevent that inner precision type instrument is oxidized, extend telescopical working life.In prior art, there is no applicable technological scheme.
Summary of the invention
The object of this invention is to provide a kind of dynamic Nitrogen filling system that is suitable for astronomical observation equipment under the condition of polar region, the precision optics equipment, particularly astronomical telescope in unmanned state of this dynamic Nitrogen filling system for using under the condition of the South Pole; This system can be filled nitrogen for a long time in good time, drives the steam of lens barrel inside, guarantees minute surface no frosting, prevents that inner precision type instrument is oxidized, extends telescopical working life.
The technological scheme that completes foregoing invention task is, a kind of dynamic Nitrogen filling system that is applicable to close astronomical observation equipment under the condition of polar region, seal closure is housed on lens cone for telescope, it is characterized in that, 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.
The lens cone for telescope inner inflatable that such scheme can be controlled solenoid valve, adopt nitrogen bottle to seal to sealed cover by rapid pipe joint and flexible pipe.
Solenoid valve is powered to it by power source special.
The present invention has following optimized project:
1, in order to guarantee to fill nitrogen year, described nitrogen bottle adopts two or more nitrogen bottles jointly for lens cone for telescope provides nitrogen, these two nitrogen bottles or a plurality of between also with flexible pipe, connect, and access in 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 suggestion adopts by the switch of iridium satellite satellite Remote solenoid valve.
3, on seal closure, load onto silicone rubber seal gasket, low temperature glue sealing for joint, connects lens barrel and seal closure, and is screwed to the slight compressive deformation of silicone rubber;
4,, between described nitrogen bottle and solenoid valve, be also provided with pressure regulator valve;
5, described rapid pipe joint adopts the joint that can tolerate polar region-80 ℃ low temperature.
Specific embodiment of the invention method is: first will on lens cone for telescope, fill seal closure, and be sealed, and use silicone rubber seal, and be screwed extremely between seal closure and lens cone for telescope and intermediate mass, 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 low temperature on solenoid valve, and is connected to lens barrel inner inflatable with lens cone for telescope 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 present invention is by the switch of iridium satellite satellite Remote solenoid valve, according to actual conditions, interval certain hour fills nitrogen, the air pressure of lens barrel inside is remained and be slightly larger than extraneous air pressure, guarantees that the air of extraneous moisture content does not enter lens barrel inside, to guarantee being dried in lens barrel, prevent minute surface frosting.
The beneficial effect of the invention
Nitrogen filling system of the present invention can meet the more year use in unmanned state under the harsh and unforgiving environments of polar region of precise light Mechatronic Systems, prevents 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 lens barrel;
3. low temperature resistant, can tolerate the low temperature of polar region-80 ℃;
4. guarantee that lens barrel is inner dry, prevent minute surface frosting;
5. lightweight, easy to carry;
6. Remote fills nitrogen as required, keeps the nitrogen pressure in lens barrel.
