Description

Be applicable to the lightweight slave mode astronomical telescope dome in the South Pole
Technical field
The invention belongs to a kind of astronomical telescope dome, be specifically related to a kind of lightweight slave mode astronomical telescope dome that is applicable to the South Pole.
Background technology
" dome " has broad sense and two kinds of implications of narrow sense usually, and the dome of broad sense is meant " dome ", is the building of settling astronomical telescope, do not receive the invasion and attack of dust storm, sleet in order to the protection telescope, and prevents that ambient temperature from changing the harmful effect to observation." dome " of broad sense include lower cylindrical shape structure " bottom dome " or be called " following dome " and be arranged on this dome top, " dome " that can rotate and open, narrow sense (being also referred to as " top hemisphere dome " or " go up dome ")." dome " in the theme of the present invention is meant the dome of broad sense.
Dome is the cylindrical structural of fixed building normally, and the top is the hemisphere housing that can make azimuth rotation--go up dome.The long and narrow trapdoor of two fans is arranged above the last dome, but along continuous straight runs separately.Have plenty of a fan skylight, can on dome, do elevating movement.In the skylight of big telescopical dome air curtain is housed, a fenestra bigger slightly than telescope bore is arranged above, let celestial body light inject.The dome hunting gear makes the air curtain fenestra follow the telescope rotation in the employing.
South Pole ice dome Dome A is positioned at the cold Antarctic Continent; Height above sea level 4093m, this place's condition of work is abominable, has only the two weeks time human work that suits now every year; Therefore existing telescope dome technology is comparatively complicated; Be generally fixed buildings, installation at short notice, the construction difficulty is very big in the Antarctic region; Sometimes snowfall is very big in the Antarctic region in addition, and heavy snow is deposited in the danger that the dome that crushes is arranged on the dome; Because the reflex of large-area accumulated snow, the ultraviolet radiation that material stood of building dome also is higher than general area.So existing general astronomical telescope dome can't be fit to installation and the requirement of use under the condition of the South Pole.The needs of Antarctic region scientific investigation and exploitation all require to provide installation and the astronomical telescope dome of use under the condition of a kind of suitable South Pole; And do not have the technical scheme that is fit in the prior art.
Summary of the invention
The objective of the invention is to remedy the deficiency of prior art, a kind of dome of installing and using of being adapted under the rigors of the South Pole is provided: a kind of lightweight slave mode astronomical telescope dome that is applicable to the South Pole.
The scheme of accomplishing the foregoing invention task is, a kind of lightweight slave mode astronomical telescope dome that is applicable to the South Pole is provided with the dome of bottom and the last dome on top, it is characterized in that,
This lightweight slave mode astronomical telescope dome directly is fixed on the astronomical telescope;
Said dome down and last dome all adopt the rope membrane structure, and this rope membrane structure comprises the skeleton that metallic rod constitutes, with the stretch-draw film that is coated on this skeleton;
The described skeleton of dome down is some parallel metallic rod annulus, forms the round platform skeleton, and this round platform skeleton external packets is covered with the stretch-draw film; This time dome is fixed on the right ascension axle turntable of astronomical telescope, rotates with the right ascension axle;
The described skeleton of going up dome is the metallic rod of some semicircles or arc, forms the clampshell structural skeleton; The external packets of this clampshell structural skeleton is covered with the stretch-draw film, constitutes hemispherical; Should go up dome and be fixed on the frame of astronomical telescope, rotate with the rotation of astronomical telescope lens barrel.
In prioritization scheme,
1, the said fixed form that goes up dome and astronomical telescope frame is: about the some semicircles of last dome skeleton or the metallic rod of arc are received respectively and be retracted within two shape of a hoof suspension ring; And suspension ring are installed on the junction plate, fix through junction plate and telescope frame; Hold left and right connecting plates with cord from the suspension ring on the frame;
2, said " going up dome is fixed on the frame of astronomical telescope ", its fixed form is: hemisphere is inserted in lens barrel from the lens barrel top; To go up dome and the tension of telescopical lens barrel with rope, guarantee sealing and fixing.
3, the said stretch-draw film bottom of dome down is provided with the shirt rim part, is provided with rope in this shirt rim part lower edge.Strain this rope and can tighten up this shirt rim part, make down right ascension axle turntable fixing tightr of dome and astronomical telescope.
In other words, the present invention uses a dome membrane structure, lattice silk and polyester material coated with a specially coated polyester lattice silk (tensioned membrane into double dome, which is lattice polyester silk, Outside is specially coated polyester lattice silk).This material is low temperature resistant, ultraviolet radiation preventing, and rain and snow, weight is light, and the dome skeleton adopts the aluminium bar to connect.Because South Pole Dome A local climate is dry, adopt scribble specific coatings wash filament crystal lattice silk fabric, can make snow landing from the dome very easily, prevented that well snow being deposited on the dome.This dome is divided into two parts up and down, and the clampshell structure is adopted on top, in the lens barrel top seal; About the skeleton of last dome is received respectively and is retracted within two shape of a hoof suspension ring; And suspension ring are installed on the junction plate, to fix through junction plate and telescope frame, following dome is fixed on the telescopical right ascension axle turntable; Not attacked by wind and snow with the protection frame, and satisfy declination axis and change day needs in district.Dome bottom round platform skeleton and stretch-draw film are fixed, and top hemisphere can rotate with the telescope declination axis and change, and the inner skeleton position is along with the rotation of declination axis changes.Whole dome rotates with the right ascension axle.The maximum characteristics of this dome are can be directly installed on the telescope, do not need power drives, and its big I designs according to telescope lens barrel amplitude of fluctuation, make the telescope running nimble, and total heavily has only 10kg, and is very light, is beneficial to telescope and follows the tracks of.Because Dome A area wind speed is less, dome is directly installed on also can not make telescope bear very big wind on the telescope to carry.
Beneficial effect of the present invention: the invention of this dome can be satisfied the requirement of polar region harsh and unforgiving environments, and its performance mainly contains following advantage:
1. easy for installation simple, 2-3 people can install successfully in 1 hour;
2. can protect telescope not receive the erosion of wind and snow, and prevent that ambient temperature from changing the harmful effect that observation is produced;
3. low temperature resistant, can tolerate the low temperature of polar region-80 ℃;
4. prevent the strong ultraviolet radiation in polar region;
5. in light weight.
