Description
Technical Field
The utility model belongs to the technical field of aerostatics, especially, relate to a nethike embrane pressure-resistant structure.
Background
The aerostat capsule is made of a light-weight high-strength film composite material, and the air tightness of the capsule is inevitably influenced by the structure configuration and the processing technology of the capsule according to the characteristics of the capsule material. Therefore, the buoyancy gas in the bag body of the aerostat leaks outwards in the using process, the buoyancy gas in the bag body is reduced, the buoyancy gas can only return to a base to supplement the buoyancy gas after leaking to a certain degree, and the aerostat is very inconvenient to maintain. Because the aerostat has extremely high requirements on weight, an overpressure gas storage device which simultaneously meets the requirements on weight and storage amount does not exist at present, and a common gas storage device has heavy weight and cannot meet the use requirements of the aerostat.
SUMMERY OF THE UTILITY MODEL
The utility model aims at in the aerostatics in-service use process, the unable real-time compensation's of helium problem provides a light nethike embrane pressure-resistant structure for helium storage and compensation.
In order to achieve the above purpose, the utility model adopts the following technical scheme to realize.
The net film pressure-resistant structure comprises a net cover and a film structure, wherein the net cover is wrapped outside the film structure.
The utility model discloses technical scheme's characteristics and further improvement do:
(1) the mesh enclosure is woven by ropes.
(2) The membrane structure is composed of multiple layers of membranes, with an internal gas filling.
(3) Each film in the film structure is formed by splicing a plurality of cut pieces or integrally formed.
(4) The multiple cut pieces of each film are welded together by the capsular bag.
(5) The meshes of the net cover are rhombic meshes or triangular meshes.
The utility model discloses technical scheme is to the unable helium compensation of present aerostatics flight in-process, and under the current situation of the weight requirement that current helium storage equipment can not satisfy again and capacity requirement, provides a light nethike embrane pressure-resistant structure for helium storage and compensation. Firstly, determining the appearance and the volume of a film structure for storing helium according to the helium leakage amount and the air-remaining time requirement of an aerostat; secondly, establishing a mesh enclosure scheme on the outer surface of the membrane structure according to the determined shape of the membrane structure; then, carrying out load calculation on the omentum structure, and determining the size of meshes and the net knot structure according to the calculation result; and finally, verifying the technical scheme of the net film by manufacturing a test piece, and determining the final scheme of the net film pressure-resistant structure according to a verification result. This withstand voltage structure of nethike embrane light in weight does not influence aerostatics flight quality, can carry out the helium to aerostatics in real time and supply, and the maintenance cost that reduces has prolonged the time of staying empty, has improved the viability.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the present invention is further described in detail by the following embodiments with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Due to the limitation of material strength and manufacturability, a single membrane structure cannot bear large internal pressure, so that more gas cannot be stored, and the use requirement cannot be met.
The utility model provides a nethike embrane pressure-resistant structure comprises membrane structure 2 and screen panel 1, and membrane structure 2 mainly forms through the welding of lamella, adopts the multilayer structure form.
Outer membrane material elastic modulus is big, warp for bear certain interior pressure load, and inner membrane material elastic modulus is little, warp greatly, do not bear interior pressure load, combines together with outer membrane material and is used for guaranteeing 2 gas tightness of membrane structure.
The net cover 1 is woven by ropes and wrapped outside the membrane structure 2 and is mainly used for bearing most of internal pressure load, and the net film pressure-resistant structure is shown in detail in figures 1 and 2. The meshes of the net cover are rhombic meshes or triangular meshes, as shown in fig. 3.
The utility model discloses technical scheme is to the unable helium compensation of present aerostatics flight in-process, and under the current situation of the weight requirement that current helium storage equipment can not satisfy again and capacity requirement, provides a light nethike embrane pressure-resistant structure for helium storage and compensation. Firstly, determining the appearance and the volume of a film structure for storing helium according to the helium leakage amount and the air-remaining time requirement of an aerostat; secondly, establishing a mesh enclosure scheme on the outer surface of the membrane structure according to the determined shape of the membrane structure; then, carrying out load calculation on the omentum structure, and determining the size of meshes and the net knot structure according to the calculation result; and finally, verifying the technical scheme of the net film by manufacturing a test piece, and determining the final scheme of the net film pressure-resistant structure according to a verification result. This withstand voltage structure of nethike embrane light in weight does not influence aerostatics flight quality, can carry out the helium to aerostatics in real time and supply, and the maintenance cost that reduces has prolonged the time of staying empty, has improved the viability.
