Description

Fastener, locking kit and stratospheric airship

Technical Field

The invention relates to the technical field of airships, in particular to a locking device, a locking external member and an stratospheric airship.

Background

The stratospheric airship has very wide military and civil values, and has great application values in the aspects of communication, remote sensing, space observation, atmospheric measurement and the like. An airship, one type of aerostat, is an aircraft that uses a lighter-than-air gas to provide lift. The lift obtained by the airship mainly comes from lighter-than-air gas filled inside the airship, such as hydrogen, helium and the like.

Because the stratospheric airship which is being developed needs to be conformal in the descending process, the stratospheric airship can be conformally descended only after the weight of the stratospheric airship is increased by inputting air into the airship to form gravity which is larger than buoyancy. During the descent process of the stratospheric airship, the stratospheric airship can be blown away by a strong wind and deviate to a far area from a preset descent point when passing through a turbulent layer. The air blower for inputting air needs to consume a large amount of energy, and the energy is remained when the stratospheric airship descends to be close to the ground. The residual energy of the system (including the capacity of the solar battery and the energy storage battery) is not enough to provide the stratospheric airship with low-altitude return fields. In addition, because stratospheric airships are bulky, transport to the hangar from areas that are far from the intended drop point is difficult.

In the prior art, an initiating explosive device is used for blasting and tearing an outer capsule of an airship on a stratosphere, and the airship is broken and falls after helium is released, so that the airship returns to the field in a preset area. However, after the stratospheric airship made of heavy metal falls from high altitude, impact force is generated to seriously damage equipment, battery packs, bag body materials and the like on the airship, so that the airship cannot be reused, and great waste is caused.

Therefore, it is necessary to provide a locking device, a locking kit and a stratospheric airship, which can help the stratospheric airship to drag, ensure the smooth connection of the stratospheric airship and the dragged airship in the air, and safely and completely return to the field.

The above information disclosed in this background section is only for enhancement of understanding of the background of the application and therefore it may contain information that does not constitute prior art that is already known to a person of ordinary skill in the art.

The first arc segment 22-3A and the second arc segment 22-3B each include a first end and a second end. The first end of the first arc section 22-3A is fixedly connected with a third gear body of a latch hook driven gear 22-2 of the latch hook gear, and the first end of the first arc section 22-3A is far away from the circle center of the third gear body and is arranged near the edge of the third gear body. The second end of the first arc section 22-3A is fixedly connected with the first end of the second arc section 22-3B, the first arc section 22-3A and the second arc section 22-3B are integrally formed, and the first arc section 22-3A is longer than the second arc section 22-3B.

The second end of the first arc section 22-3A extends towards the groove direction, and the size of the second arc section 22-3B is smaller than that of the groove 22-8A, so that the second end of the first arc section 22-3A and the second arc section 22-3B can be driven to be far away from or extend into the groove 22-8A when the latch hook gear rotates; when the second arc 22-3B extends into the groove 22-8A, the deadbolt rack 22-5 is higher than the second end of the second arc 22-3B, the second end of the second arc 22-3B being closer to the opening 22-8C than the first end.

The latch hook motor 22-7 drives the latch hook driving gear 22-1 to rotate. Deadbolt motor 22-4 rotates deadbolt gear 22-6.

As shown in fig. 1 and 2, the shackle gears are located on the same side of recess 22-8A as chamber 22-8B.

When the locking device 22 is locked, the bolt rack 22-5 extends into the groove 22-8A until the second arc section 22-3B of the locking hook member 22-3 is clamped, so that the locking device platform 22-8, the locking hook gear, the locking hook member 22-3 and the bolt rack 22-5 form a closed loop to realize locking.

As shown in fig. 3 and 4, the collar 12 includes: an outer ring shell 12-1, an inner ring rack 12-2, a lantern ring gear 12-4 and a lantern ring motor 12-3.

The lantern ring motor 12-3 drives the lantern ring gear 12-4 to rotate, and further drives the inner ring rack 12-2 to rotate.

The outer ring shell 12-1 is of an arcuate configuration. Both ends of the outer ring shell 12-1 are provided with a lantern ring opening.

The inner ring rack 12-2 is an arc-shaped structure. The center of the inner ring rack 12-2 coincides with the center of the outer ring shell 12-1. The inner ring rack 12-2 can extend out of the outer ring shell 12-1 from one lantern ring opening and can extend into the outer ring shell 12-1 from the other lantern ring opening under the driving of the lantern ring gear 12-4.

When the inner ring rack 12-2 extends out of the outer ring shell 12-1 from one ring opening and extends into the outer ring shell 12-1 from the other ring opening, the inner ring rack 12-2 and the outer ring shell 12-1 form a complete ring structure, and the ring 12 is in a closed ring state. When the lantern ring 12 is changed from the closed ring state to the open ring state, only the inner ring rack 12-2 needs to rotate into the outer ring shell 12-1, so that the structure formed by the outer ring shell 12-1 and the inner ring rack 12-2 is an arc-shaped structure.

The diameter of collar 12 (i.e., the diameter of inner ring rack 12-2 and outer ring housing 12-1) is larger than second arc 22-3B so that collar 12 can telescope into latch 22 from second arc 22-3B.

The closed loop kit may be used for locking, connection of components, etc., preferably, for connection between two aerial vehicles.

When it is desired to connect an airborne towing airship 1 and a stratospheric airship 2, as shown in figure 3, the collar 12 is closed, as shown in figure 2, the latch 22 is unlocked and the locking bolt rack 22-5 is located in the chamber 22-8B. The lantern ring 12 is sleeved in from the second arc section 22-3B, and after the lantern ring 12 is sleeved in, the second arc section 22-3B is arc-shaped, so that the lantern ring 12 can be hooked to prevent the lantern ring 12 from being separated. The latch hook motor 22-7 drives the latch hook driving gear 22-1 to rotate, and the latch hook driving gear 22-1 drives the latch hook driven gear 22-2 to rotate. The latch hook driven gear 22-2 rotates clockwise so that the second end of the first arc segment 22-3A and the second arc segment 22-3B are adjacent to the groove 22-8A until reaching the groove 22-8A; then the bolt motor 22-4 drives the bolt gear 22-6 to rotate, the bolt gear 22-6 rotates clockwise to drive the bolt rack 22-5 to extend from the chamber 22-8B to the groove 22-8A through the opening 22-8C until the second arc section 22-3B of the lock hook member 22-3 is clamped, as shown in fig. 1, the tightener platform 22-8, the lock hook driven gear 22-2 of the lock hook gear, the lock hook member 22-3 and the bolt rack 22-5 form a closed loop, and the lantern ring 12 is sleeved on the lock hook member 22-3, so that the connection of the towing airship and the stratospheric airship in the air is realized.

When it is desired to release the connection between the towed airship 1 and the stratospheric airship 2 in the air, the latch 22 is in a latched state as shown in fig. 1, and the collar 12 is in a closed loop state as shown in fig. 3. Because second arc 22-3B of latch 22 is hook-shaped, collar 12 is difficult to fly out of second arc 22-3B. Therefore, when the towing airship needs to be detached, the lantern ring motor 12-3 of the lantern ring 12 drives the lantern ring gear 12-4 to rotate, the inner ring rack 12-2 is retracted into the outer ring shell 12-1, the whole lantern ring 12 is changed into an arc shape from a circular shape, as shown in fig. 4, the lantern ring 12 is in an open ring state, and the lock hook member 22-3 is disconnected from the lantern ring 12 through a notch below the lantern ring 12, so that the towing airship 1 and the stratospheric airship 2 are detached.

By the method, the dragging airship 1 and the stratospheric airship 2 can be quickly connected and disconnected in the air, the complete and safe recovery of the stratospheric airship 2 is ensured, and the stratospheric airship is prevented from being remotely moved on the ground.

According to a second embodiment of the present invention, the present invention provides a locking assembly, which has a structure substantially the same as that of the locking assembly of the first embodiment, except that the locking assembly of the second embodiment has a plurality of locking hook members 22-3, and the plurality of locking hook members 22-3 form a fan-shaped structure with the connection point of the first arc 22-3A and the locking hook gear as a circle center, so as to facilitate grasping the collar 12.

According to a third embodiment of the present invention, there is provided a stratospheric airship 2, as shown in fig. 5, comprising a latch 22 of the latch kit of the first embodiment or the second embodiment and a stratospheric airship body 21.

The lock 22 is provided at the front end of the stratospheric airship body 21 so that the stratospheric airship 2 can be towed by the towing airship 1.

The towing airship 1 comprises a towing airship body 11 and a collar 12. Collar 12 and latch 22 comprise a latch set. The lantern ring 12 is arranged at the rear part of the towing airship 1 and is connected with the towing airship body 11 through a towing rope.

The method for dragging the airship 1 to drag the stratospheric airship 2 to return to the field comprises the following steps:

step S1: and (4) descending the stratospheric airship 2 to a medium-low altitude airspace. At the moment, the stratospheric airship 2 consumes a lot of energy for shape preservation in the running and descending processes, and the energy is not enough to control the stratospheric airship 2 to directly run to a preset recovery area when the airship goes to a low-medium airspace.

Step S2: as shown in fig. 5, the towing airship 1 will be driven forward of and above the stratospheric airship 2.

Step S3: and adjusting the speed and height of the towing airship 1 and the stratospheric airship 2, vertically and downwards releasing the towing rope, locking the lantern ring 12 with the locking device 22, and stopping releasing the towing rope.

Step S4: as shown in fig. 6, the towing airship 1 is controlled to tow the stratospheric airship 2 to fly towards a predetermined recovery area.

Step S5: after a preset recovery area is reached, the comprehensive control system 3 controls the towing airship 1 and the stratospheric airship 2 to descend at the same height until a specified height (height capable of freely and safely descending) and a specified recovery point are reached, the connection between the lantern ring 12 and the locking device 22 is released, the towing airship 1 and the stratospheric airship 2 are in contact traction state, the towing airship 1 and the stratospheric airship 2 are separated, the stratospheric airship 2 is recovered, and the towing airship 1 is recovered at the same time.
