Abstract

The invention discloses a free telescoping device for a non-hard stratospheric airship, which belongs to the technical field of non-hard stratospheric airships, and solves the problems of high possibility of deformation and even breaking of an airship body bearing different pressures generated by large change of the volume of internal gas due to large change of environment temperatures in the flight process of a non-hard stratospheric airship. The free telescoping device for the non-hard stratospheric airship comprises an airship body, wherein the middle of the airship body is folded; the outer edge of the folded part is connected with the outer surface of the rear part of the airship body through a plurality of tension springs; the inner edge of the folded part is connected with the inner surface of the front part of the airship body through a plurality of tension springs. The free telescoping device for the non-hard stratospheric airship is used for preventing the high possibility of deformation and even breaking of the airship body bearing different pressures generated by the large change of the volume of the internal gas due to the large change of the environment temperatures in the flight process of the non-hard stratospheric airship.

Description

Non-rigid stratospheric airship free-extension device

Technical field

The invention belongs to non-rigid stratospheric airship technical field, be specifically related to a kind of non-rigid stratospheric airship free-extension device.

Background technology

Non-rigid stratospheric airship, in flight course, because the change of ambient temperature, than the volume of its internal gas of ambassador, larger change occurs, causes ship easy distortion when bearing different pressures even to be broken.

Summary of the invention

The objective of the invention is for solution by no means rigid stratospheric airship in flight course, because the change of ambient temperature, than the volume of its internal gas of ambassador, larger change occurs, cause the ship problem that easy distortion is even broken when bearing different pressures, a kind of non-rigid stratospheric airship free-extension device is provided, and its technical scheme is as follows:

A kind of non-rigid stratospheric airship free-extension device, it comprises the ship body, the centre of described ship body is folding, and by the outward flange of burst and ship after one's death the part outside face by many extension springs, be connected, the inward flange of burst is connected by many extension springs with ship body leading portion inside face.

Beneficial effect of the present invention is: prevent that non-rigid stratospheric airship is in flight course, because the change of ambient temperature, than the volume of its internal gas of ambassador, larger change occurs, cause ship easy distortion when bearing different pressures even to be broken.

the accompanying drawing explanation:

Fig. 1 is outside perspective view of the present invention;

Fig. 2 is vertical cross-sectional schematic of the present invention;

Fig. 3 is the extension spring connection diagram of burst of the present invention;

Fig. 4 is extension spring of the present invention and lacing wire multiple spot connection diagram;

Fig. 5 is the structure cross-sectional schematic of extension spring and sleeve in the present invention.

the specific embodiment:

With reference to Fig. 1-Fig. 5, a kind of non-rigid stratospheric airship free-extension device, it comprises ship body 1, the centre of described ship body 1 is folding, and by the outward flange 1-1 of burst and ship after one's death the part outside face by many extension springs 2, be connected, the inward flange 1-2 of burst is connected by many extension springs 2 with ship body leading portion inside face.

The lacing wire 3 of an annular respectively is set at the inward flange 1-2 place of the outward flange 1-1 place of the trailing portion outside face of the leading portion inside face of described ship body 1, ship body 1, burst and burst, lacing wire 3 is overlapped 3-1 with ship body 1 by lacing wire and is connected, lacing wire 3 is arranged in lacing wire cover 3-1, and lacing wire cover 3-1 is fixedly connected with ship body 1; The lacing wire 3 that the outward flange 1-1 place of burst arranges is connected with the two ends of many extension springs 2 respectively with the lacing wire 3 that ship body 1 trailing portion outside face arranges; The lacing wire 3 that the inward flange 1-2 place of burst arranges is connected with the two ends of many extension springs 2 respectively with the lacing wire 3 that ship body leading portion inside face arranges.

Preferably, described extension spring 2 and the junction of lacing wire 3 are at 2 and are connected or multiple spot connects.

Preferably, described many extension springs 2 outsides are provided with sleeve 2-1, described sleeve 2-1 comprises inner sleeve 2-1-1 and two outer sleeve 2-1-2, two outer sleeve 2-1-2 are sleeved on the left and right sides of inner sleeve 2-1-1, and the outside one end of two outer sleeve 2-1-2 is connected with the two ends, left and right of extension spring 2 respectively; The outside one end sealing of described two outer sleeve 2-1-2 also is provided with circular hole in center, and the two ends, left and right of extension spring 2 are stretched out by the circular hole place and are connected with closed end, and two outer sleeve 2-1-2 can move with the flexible of extension spring 2, reduce 1 wearing and tearing of 2 pairs of ship bodies of extension spring.

The principle of invention: during variation of ambient temperature, the interior gas of ship increases or reduces the pressure of ship body 1, can change the size that length that the width of burst and extension spring stretch is regulated space in ship, thereby prevent that non-rigid stratospheric airship is in flight course, because the change of ambient temperature, than the volume of its internal gas of ambassador, larger change occurs, cause ship easy distortion when bearing different pressures even to be broken.
