A mounting platform 101 is arranged at the bottom of the UAV body 1; the energy storage device 2 is arranged below the mounting platform 101; the energy supply component 4 is arranged around the outer periphery of the energy storage device 2, and multiple groups of rotatable groups are arranged. On the one hand, by rotating, wind energy in the corresponding direction is collected and supplied to the energy storage device 2; on the other hand, by rotating, the position is adjusted to provide protection for the energy storage device 2; the chassis 3 is located at the bottom of the energy storage device 2, and its position is opposite to the mounting platform 101; the protective shield 6 is respectively installed on the chassis 3 by sliding up and down, and multiple groups of protective shield 6 are arranged around the outer periphery of the energy storage device 2; the winding positioning member 50 in the positioning component 5 1 is located below the chassis 3, and the mobile positioning member 502 is connected to the winding positioning member 501 through the positioning rope 503; when flying or stopping, the positioning rope 503 is shortened, and the mobile positioning member 502 lifts up the protective shield 6 while fitting the winding positioning member 501. At this time, the positioning component 5 occupies a small space, and the protective shield 6 can effectively prevent external force impact; when concentrated energy storage is performed, the positioning rope 503 is extended, and the mobile positioning member 502 is separated from the winding positioning member 501, and the protective shield 6 loses support and falls. The surroundings of the energy storage device 2 are lost, and the air circulation is increased, which is not only beneficial to the collection of wind energy, but also beneficial to heat dissipation.

[0046] like Figure 4 As shown, the protective shield 6 and the energy supply assembly 4 are arranged in an alternating manner to achieve all-round protection for the energy storage device 2 .

[0047] like Figure 5As shown, the energy storage device 2 includes an energy storage box 201; an energy storage controller and a battery are arranged in the energy storage box 201, a detachable energy storage seat 202 and a mounting platform 203 located on the outer periphery of the energy storage seat 202 are arranged on the top; the energy storage seat 202 is located on the mounting platform 101, and a through hole for the line to pass through is arranged on the energy storage seat 202; the energy storage controller is connected to the control signal on the drone body 1; the battery is respectively connected to the energy supply component 4 and the drone body 1; the electrical connector 204 is arranged on the energy storage box 201 and is also connected to the battery; therefore, the wind energy collected by the energy storage device 2 can be used to power the drone body 1, and can also be used to power other external electrical equipment.

[0049] It should be further explained that the protective shield 6 is plate-shaped, and limit heads are provided at the upper and lower ends.

[0050] When flying or stopped, the protective shield 6 is in a raised state, which can effectively prevent external impact from protecting the energy storage device 2 from the periphery. When concentrated energy storage is in progress, the protective shield 6 loses support and falls, and the energy storage device 2 loses its surroundings, increasing air circulation, which is not only conducive to collecting wind energy, but also conducive to heat dissipation.

[0051] like Figure 5 As shown, the winding positioning member 501 is a winding box, which is surrounded by multiple groups of through slots 301, and an electric reel for winding the head end of the positioning rope 503 is arranged in the box; when positioning is required, the electric reel can be rotated to lengthen the positioning rope 503.

[0054] When the positioning rope 503 is shortened, the movable frame 50201 moves to fit the bottom of the winding box. The top blocks 50204 extend into the through slots 301 one by one, lift up the protective shield 6, and enter the protection mode. When the positioning rope 503 is extended, the movable frame 50201 moves away from the bottom of the winding box. The top blocks 50204 exit the through slots 301 one by one, and the protective shield 6 descends, and enters the ventilation mode.

[0057] The wind energy sensor 405 senses the wind direction and wind force, and the mounting sleeve 402 and the mounting shaft 404 rotate to adjust the angle between the blades of the wind propeller 407 and the wind direction to maintain the rotation speed of the wind propeller 407 and improve the efficiency of wind energy collection.

[0058] It should be further explained that the installation sleeve 402 rotates along the horizontal plane; the installation shaft 404 rotates along the vertical plane; through the staggered rotation of the installation sleeve 402 and the installation shaft 404, the adjustment range is increased, which is beneficial to wind energy collection.

[0059] It should be further explained that four groups of energy supply components 4 are arranged, which are respectively located in front, behind, left and right of the energy storage device 2; each group of energy supply components 4 is provided with two groups of mounting frames 403; the two groups of mounting frames 403 are perpendicular to each other to form a right-angle structure; in the protection mode, according to the direction of the obstacle, the two groups of right-angle structures on the corresponding sides are rotated to be close to or connected at the ends, so as to directly intercept the obstacle from the front of the energy storage device 2, cushion the impact head-on, and improve the protection effect.

[0060] It should be further explained that an obstacle sensor is provided on the mounting frame 403 to detect and determine the direction of obstacles through ultrasonic, infrared, electromagnetic waves or visual means to assist in protection.
