The specific embodiment
Below in conjunction with the accompanying drawing embodiment that develops simultaneously, describe the present invention.
Present embodiment provides a kind of spacecraft house refuse flinger, and is as shown in Figure 1.Adopt this projector can house refuses such as stool be thrown to the earth with sufficiently high speed, the spacecraft internal gas is leaked.
This spacecraft house refuse flinger comprises motor 1, cylinder 7, piston 6, driven gear 2, driving gear 3, screw rod 5, garbage tank 8 and tooth rest 4.Wherein garbage tank 8 is a bullet shape, the sealing of one of which end, and the other end is through garbage tank 8 end caps that are threaded, and inside is used for holding house refuse.
Said cylinder 7 is a cylindrical structural, and its exit end inwardly shrinks, outer likeness in form shell case of the no end.The arrival end of cylinder 7 is positioned at spacecraft inside, is connected with tooth rest 4; In the space of exit end between spacecraft inwall 9 and spacecraft outer wall 10, be used to install garbage tank 8.The diameter coupling of the diameter of cylinder 7 exit end and garbage tank 8 band edges lid side can be installed on the cylinder 7 garbage tank 8 closely, and can under the effect of certain thrust, break away from from cylinder 7.Piston 6 is housed in the cylinder 7; One end of screw rod 5 is fixed on the center of piston 6 end faces through screw rod 5 covers; The other end passes driven gear 2 successively and is fixed on the bearing on the tooth rest 4; Said bearing is installed in driven gear 2 on the tooth rest 4, and driven gear 2 centers are processed with the negative thread that cooperates with screw rod 5.The distance of driven gear 2 and cylinder 7 arrival end ends should guarantee to retreat to the position of driven gear 2 applyings the time when piston 6, in garbage tank 8 can be packed cylinder 7 into from cylinder 7 arrival ends smoothly.Coaxial with motor 1 with driven gear 2 ingear driving gears 3, motor 1 drives driving gear 3 and rotates.Motor 1 is fixed on the spacecraft inwall 9.Said cylinder 7 exit end pass towards the earth one side's spacecraft inwall 9, and over against spacecraft outer wall mouth 11, the excircle of cylinder 7 and 9 sealings of spacecraft inwall guarantee that the head that garbage tank 8 back garbage tanks 8 are installed can not touch spacecraft outer wall 10.
The principle of work of this spacecraft house refuse flinger is:
When this flinger did not use, when piston 6 was positioned at the position of fitting with driven gear 2, spacecraft outer wall mouth 11 was closed.When needs impelling house refuse, house refuse is packed in the garbage tank 8, and tighten garbage tank 8 end caps; Then with garbage tank 8 from the arrival end of cylinder 7 pack into cylinder 7 pushers to cylinder 7 exit end and compress, guarantee the sealing of cylinder 7 exit end.Open spacecraft outer wall mouth 11, because cylinder 7 excircles and 9 sealings of spacecraft inwall, the air in the cabin can not leak by space-ward.Starter motor 1; Motor 1 drives driven gear 2 through driving gear 3 and rotates, and 5 of driven gear 2 and screw rods pass through screw thread fit, because the friction between piston 6 and cylinder 7 inside faces is bigger; The rotation of restriction screw rod 5, thus screw rod 5 is moved along cylinder 7 axis directions.Screw rod 5 drives piston 6 entering cylinders 7 and moves along cylinder 7 axis directions.Because air has got into cylinder 7 in the cabin, after piston 6 got into cylinder 7 fully, the air in the cylinder 7 began to be compressed; And along with reducing of volume of air; Gas progressively increases the pressure of garbage tank 8, and when internal pressure surpassed cylinder 7 wall ends to the restriction of garbage tank 8, garbage tank 8 was gone out by impelling fast; Leave spacecraft, fly to the earth.After garbage tank 8 is by impelling, spacecraft outer wall mouth 11 is closed.
Because garbage tank 8 possesses the rate of onset of certain sensing earth, get into atmospheric envelopes and quilt is burnt through back garbage tank 8 after a while, so can not form space junk.In addition after garbage tank 8 is dished out owing to piston 6 still in cylinder 7, so the spacecraft internal gas can not leak.
It is closely related that cast and garbage tank 8 are installed in the tightness of cylinder 7 exit end, also with cylinder 7 during by piston 6 sealings the volume of internal gas closely related.The ejection velocity that therefore will improve garbage tank 8 just need slightly increase the size of garbage tank 8, and it is installed on the cylinder 7 more tightly; Perhaps getting into cylinder 7 backs at piston 6 inflates to increase the quality of cylinder 7 gases to cylinder body through an induction opening that is positioned on the inner cylinder body of spacecraft.
Although the space rarefaction of air of spacecraft flight neither not have air purely, so spacecraft will rub with air in the space operational process inevitably, and orbit altitude is slowly descended.The track that must carry out spacecraft for the normal operation that guarantees spacecraft keeps, and promptly utilizes self-contained fuel to be the spacecraft rail lift over time.Because the spacecraft travel direction is opposite with garbage tank 8 travels direction; And under the certain situation of garbage tank 8 quality; It is fast more by the speed of impelling; The speed that spacecraft moves is also fast more, this shows that spacecraft house refuse flinger can also play the effect that promotes the spacecraft orbit height.
In sum, more than being merely preferred embodiment of the present invention, is not to be used to limit protection scope of the present invention.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
