Further, as shown in fig. 1-2, a floating cavity 11 which is telescopic between an expansion state and a contraction state is defined in the airship body 1, the floating cavity 11 is filled with an inert gas whose density is less than that of air, so that the airship body 1 floats in the air, that is, the airship body 1 is a cavity structure with the floating cavity 11 inside, and the floating cavity 11 is filled with the inert gas whose density is less than that of air, so that the airship body 1 can be driven to float in the air, and because the airship body 1 is a dielectric elastic material, when the volume of the airship body 1 expands, the volume of the floating cavity 11 increases, but because the mass of the inert gas in the floating cavity 11 does not change, the density of the inert gas further decreases, the buoyancy increases, so that the airship body 1 can be driven to float upwards, and similarly, when the volume of the airship body 1 contracts, the volume of the floating cavity 11 becomes smaller, but the mass of the inert gas in the floating cavity 11 is not changed, so that the density of the inert gas is increased, the buoyancy is reduced, and the airship body 1 can be driven to sink.

Specifically, the inert gas in the floating chamber 11 may be helium or the like.

In a specific embodiment, when the airship body 1 is filled with the inert gas, the filling may be performed by the following steps: firstly, the airship body 1 in a normal state (namely, a non-electrified state) is filled with sufficient inert gas, then the airship 10 is tested for the suspension performance, the buoyancy of the airship 10 is slightly lower than the air buoyancy, when the airship is put down from the high air, the airship 10 can slowly fall to the ground, so that the airship 10 can float after the volume of the airship body 1 expands after the airship body 1 is electrified, and the airship 10 can slowly fall to the ground after the airship body 1 is powered off, thereby ensuring the normal work of the airship 10.

According to an embodiment of the present invention, the airship body 1 is provided with a body electrode, and the body electrode is electrically connected to the power supply 6, so that the airship body 1 is electrically connected to the power supply 6 through the body electrode, and specifically, the body electrode may be distributed at the position of the suspension cavity of the airship body 1, so as to ensure that the volume of the suspension cavity may be increased when the power supply 6 is powered on.

According to one embodiment of the invention, as shown in fig. 1-2, the propulsion device 2 comprises: first plectrum 21, second plectrum 22, first plectrum 21 is located the left and right sides of dirigible body 1, and the orientation is kept away from the direction extension of dirigible body 1, first plectrum 21 can carry out the swing of upper and lower direction, therefore, when first plectrum 21 swings, can carry out the propulsive force of upper and lower direction to dirigible body 1, and first plectrum 21 is located the left and right sides of dirigible body 1, thereby be favorable to stabilizing dirigible body 1, prevent that dirigible body 1 from taking place the circumstances such as turn on one's side, and then guarantee that the job stabilization nature of dirigible 10 is higher, and, because first plectrum 21 can carry out the swing of upper and lower direction, can also carry out micro-adjustment to the height of dirigible body 1 through the swing of first plectrum 21, thereby guarantee that the height control of dirigi.

Further, the second paddle 22 is located at the rear side of the airship body 1 and extends in the direction away from the airship body 1, and the second paddle 22 can swing in the front-rear direction, so that when the second paddle 22 swings, the airship body 1 can be propelled in the front-rear direction, and the airship body 1 can be advanced or retreated, and by controlling the swing angle of the second paddle 22, the airship body 1 can be steered and controlled, so that the airship 10 can be moved flexibly in the air.

In a specific embodiment, the propulsion device 2 may be configured as a fin-shaped structure by using bionics, wherein the first paddle 21 may be configured as a fin-shaped structure, and the second paddle 22 may be configured as a fin-shaped structure, so as to ensure that the airship 10 moves more reliably and flexibly.

According to one embodiment of the present invention, the first paddle 21 is formed as a piezoelectric material, the upper and lower end surfaces and the middle position of the first paddle 21 in the thickness direction are provided with the smear electrodes, the smear electrodes are electrically connected to the power supply 6, the second paddle 22 is formed as a piezoelectric material, the upper and lower end surfaces and the middle position of the second paddle 22 in the thickness direction are provided with the smear electrodes, and the smear electrodes are electrically connected to the power supply 6. The first pick 21 is switched among the first state, the second state and the third state, thereby driving the airship 10 to move.

That is, the propelling device 2 is a piezoelectric material, and when a voltage is applied to two ends of the piezoelectric material, the piezoelectric material contracts or expands, so that the propelling device 2 can swing, and since the swing principle of the first pulling piece 21 is the same as that of the second pulling piece 22, the propelling principle of the propelling device 2 will be described below by taking the first pulling piece 21 as an example.
