Abstract
The present lens of space telescope must be thicker and stronger, and its overload is 3-4G when rocket is launched. The invention provides a liquid filling barrel, wherein a lens of a telescope is placed in the barrel, and the liquid and the barrel bear the hydraulic pressure of acceleration inversion, so that the lens is not influenced by overload and is not deformed. By using the technology, the cable system can be switched into the lens when the lens is launched, thereby reducing the launching cost. The overall mass of the telescope is much less and the attitude adjustment in space is much easier.
Description
Technical Field
The invention relates to a protective device for a space telescope lens, in particular to a protective device for a polygonal barrel and a space telescope lens.
Background
At present, the overload during rocket launching is 3-7G. In order to avoid overload during launching and prevent the lens from being stressed by acceleration during launching to deform the lens, the space telescope can only thicken the lens or add ribs, and a support must be added during launching to keep the shape unchanged. The support is thick, and whole quality is big, and is with high costs.
The manufacturing precision of the front surface of the lens can reach 100 nanometers. The lens has very high smoothness and a complex cleaning process. The back of the lens is provided with a rib.
The light collecting area of the Weber space telescope is 25m2The mass of the lens per square meter is more than 15kg, and a complex bracket is required to support the lens during shooting, so that the lens is shot vertically, and the weight of the bracket is evenly distributed on the lens and can reach more than 20kg per square meter. In the future, the launching of the cable system is too idle, and although the launching cost per unit weight is much lower, the overload of the cable system can reach more than 20G, or more challenges are presented. In future, space telescopes with the diameter larger than 5 meters generally adopt spliced main mirrors, namely the main mirrors are divided into a plurality of small lenses, and most of the space telescopes are divided into regular hexagonal small lenses.
Disclosure of Invention
The invention provides a protective device for lenses of a polygonal barrel and a space telescope, aiming at solving the problems that the existing lenses are stressed due to overload, the lenses are deformed, the lenses and a bracket have large mass and high cost. It uses a polygonal barrel to bear the overload pressure of liquid, and uses the incompressible property of liquid to offset the overload of lens.
A specific solution to this problem requires the use of a polygonal barrel. The cross sections of the barrel body, the barrel bottom and the barrel cover of the polygonal barrel are polygons; a round outer barrel is arranged outside the polygonal barrel, and a filler is arranged between the polygonal barrel and the outer barrel and is a solid.
The size of the polygonal barrel is just enough to be put into the outer barrel. The polygonal barrel matches the shape of the lens, which is also a square if it is a square, a regular hexagon if it is a regular hexagon, and is just as large as being able to lay the lens flat. The lenses are mostly hexagonal and thus the polygonal barrels are mostly hexagonal. The size of the polygonal barrel can be just placed in the outer barrel. The outer barrel and the solid filler are used for bearing the hydraulic pressure of the polygonal barrel.
Further, the bottom of the outer barrel is hemispherical and is filled with filler.
Furthermore, a piston is arranged in the polygonal barrel, liquid is arranged between the piston and the barrel bottom, and a pipeline is arranged at the barrel bottom. When the lens is put in, the lens is put in at the barrel opening, and the liquid flows out of the pipeline, and the put-in lens and the piston are pushed to move downwards. Therefore, the lens is only required to be placed at the opening of the barrel when being placed, otherwise, the lens is required to be placed from the bottom of the barrel, and the time is consumed. The speed of putting the lens in the method is high.
Furthermore, a heat insulation layer is arranged outside the polygonal barrel, and a rubber sheet can be pasted to serve as the heat insulation layer.
The specific technical scheme 1 for solving the problem of lens protection is as follows:
a protective device for stacking lenses by using a polygonal barrel, which adopts any one of the polygonal barrels, wherein the polygonal barrel is matched with the carried lens in shape; the body of the polygonal barrel is provided with a vertical dovetail groove; a circle of sealing ring is arranged at the edge of each lens; the lens is provided with a raised dovetail joint, the size of the dovetail joint is matched with the dovetail groove, and the dovetail joint can move up and down in the dovetail groove; the piston is arranged below the lens, and liquid is arranged between the lenses in the polygonal barrel; the lens is provided with an isolation net above and below.
Each side of the polygonal barrel is provided with 2-50 dovetail grooves, and correspondingly, the lens is provided with the same number of dovetails. The separation net is a plurality of threads or belts which separate the upper lens from the lower lens.
When the lenses are loaded, in a working chamber without air and only with vapor of the liquid, a certain amount of liquid is injected into the polygonal barrel every time one lens is placed, so that the uppermost lens is always immersed by the liquid. After a lens is put in, liquid flows out from a gap between the sealing ring and the polygonal barrel so as to prevent the liquid under the lens from being too much.
Further, the liquid is selected from liquid hydrogen because of its low density.
Furthermore, a compression ring can be arranged at the opening of the polygonal barrel, a spring is arranged on the compression ring, the barrel cover is closed after the lens is filled, and the barrel cover compresses the spring, the compression ring and the sealing ring. If the pressing ring and the spring are not arranged, the sealing ring can be directly pressed by the barrel cover.
Furthermore, the sealing ring is provided with an opening, a lens is placed at the barrel opening, and when one lens is placed, after partial liquid flows out of the opening, the opening is blocked by the plug, and then the previous layer of lens is placed.
Further, the lens has horizontal screw holes, and the dovetail is connected to the lens through the screw holes.
Further, the liquid may be selected to be alcohol and correspondingly the solid filler may be selected to be hydrogen peroxide.
The second kind of protective device for stacking lenses by using a polygonal barrel has the following technical scheme:
a polygonal barrel as claimed in any one of the preceding claims. The lens is packed into a film bag; injecting liquid into the film bag, wherein the volume of the liquid is larger than the space occupied by each layer of lens; the thin film bag is sealed and then put into a polygonal barrel.
The lenses are placed into a film bag, then a liquid is injected into the film bag in an amount greater than the void space occupied by each layer of lenses, then the film bag is sealed, and then the lenses are placed layer by layer.
The so-called void space calculation method is as follows: if the area of the lens is s and the occupied height is h, the occupied space is s x h, and the volume of all solid parts of the lens is subtracted from s x h, so that the space is the void space. Void space is the space occupied by ribs, connectors or other protrusions.
The film bag can be formed by using two films which are larger than the lens and are bonded at the edge of the lens to form a bag. Or an open film bag, filled with the lens and then glued open.
The liquid is preferably liquid hydrogen.
The sealing ring and the film bag are preferably made of polyimide plastic.
The invention has the beneficial effects that:
the liquid has incompressibility, and by utilizing the characteristic, the volume of the liquid hydrogen between the two lenses cannot be reduced and the distance cannot be reduced during launching, and in addition, the separation net is arranged between the two lenses, so that the lenses cannot be extruded, abraded and deformed. By adopting the technology, the over-running cable system with low launching cost can be utilized in the lens launching process, so that the launching cost is reduced. The thickness of the lens can be only 1mm, the weight of each square meter only needs 1-4 kg, and the manufacturing cost is reduced to a certain extent. More importantly, the total weight of the lens support is reduced by more than 70%, and the overall mass of the space telescope is reduced by more than 20-50%. The attitude of the telescope is much easier to adjust in space. In addition, the solid filler can be melted to obtain liquid. The filler and the liquid can be used as rocket fuel to push the space telescope to continue to change orbit or stay in space for standby. The present invention takes advantage of the incompressibility of liquids. The device of the invention can be used for quickly placing the lens. And in the process of putting the lens, the sealing ring is always pressed, so that liquid leakage is reduced.
