[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0038] A fire-fighting drone for rapid detection of forest fires specifically includes a shell 1, a groove 101 is provided on the upper surface of the shell 1, a protective cover 102 is fixedly connected to the inner wall of the groove 101, a protective shell 103 is rotatably connected to the inner bottom surface of the protective cover 102, a plurality of guide plates 104 are arranged in a circular array on the outer surface of the protective shell 103, a connecting block 105 is abutted on the outer surface of the guide plate 104, a ventilation pipe 106 passes through the connecting block 105, and the other end of the ventilation pipe 106 is connected to a wind collecting cover 107, and a plurality of through holes 108 are provided on the outer surface of the protective shell 103 near the lower end.

[0039] When the drone is extended in flight, the wind energy generated by the drone propeller 701 is collected into the wind collecting hood 107 and enters the protective cover 102 along the ventilation duct 106. The collected wind energy blows the guide plate 104, and the blown guide plate 104 rotates. During the rotation, the solar cell panel 5 on the outer surface of the protective shell 103 is rotated. During the rotation, the solar cell panels 5 in multiple positions can be collected to improve its endurance. In addition, the generated wind energy can be used to generate electricity through the differential 301 and the generator 402 to achieve improved endurance on cloudy days.

[0040] A plurality of ventilation pipes 106 are fixedly connected to the inner wall of the protection shell 103 , and a connecting rod 202 is fixedly connected at the center of the plurality of ventilation pipes 106 .

[0041] The ventilation pipe 106 fixedly connected to the inner wall of the protective shell 103 is used to collect wind energy, and the connecting rod 202 fixedly connected at the center of the ventilation pipe 106 is used to connect the ventilation pipe 106 and the differential 301 .

[0042] The upper end of the connecting rod 202 is connected to the differential case 3, and the inner surface of the differential case 3 is fixedly connected to the differential 301, and one end of the differential 301 is fixedly connected to the connecting rod 202. The other end of the differential 301 is fixedly connected to the generator 402, and the output end of the generator 402 is fixedly connected to the battery 401.

[0043] The differential case 3 connected through the upper end of the connecting rod 202 is used to fix the differential 301, and the differential 301 fixedly connected to the inner surface of the differential case 3 is used to adjust the speed of the connecting rod 202 and drive the generator 402 to work and generate electricity.

[0044] A plurality of solar panels 5 are arranged in a circular array on the outer surface of the protective shell 103 . The solar panels 5 are arranged in multiple groups, and each group of solar panels 5 penetrates the protective shell 103 and is fixedly connected to the battery 401 .

[0045] A plurality of solar panels 5 in an annular array on the outer surface of the protective shell 103 are used to collect solar energy. Each group of solar panels 5 penetrates the protective shell 103 and is fixedly connected to the battery 401 so as to transmit the collected solar energy to the inside of the battery 401 and convert it into electrical energy.

[0046] A connecting frame 6 is fixedly connected to the outer surface of the housing 1 , and a servo motor 4 is fixedly connected to the other end of the connecting frame 6 .

[0047] The connecting frame 6 fixedly connected to the outer surface of the shell 1 is used to connect the shell 1 and the servo motor 4. The servo motor 4 fixedly connected to the other end of the connecting frame 6 is used to drive the support shaft 7 to rotate. The rotation of the support shaft 7 drives the propeller 701 to rotate to realize the lifting and lowering of the drone.

[0048] The output end of the servo motor 4 is fixedly connected to a support shaft 7, the outer surface of the support shaft 7 is fixedly connected to a propeller 701, the upper end of the support shaft 7 is rotatably connected to a wind collecting cover 107, and the wind collecting cover 107 shrinks from the upper end to the lower end to form a funnel shape.

[0049] The support shaft 7 fixedly connected to the output end of the servo motor 4 is used to control the rotation of the propeller 701, thereby realizing the lifting and lowering of the UAV. The wind collecting hood 107 fixedly connected to the upper end of the support shaft 7 is used to collect the wind energy generated above the propeller 701. The wind collecting hood 107 shrinks from the upper end to the lower end into a funnel shape so that the propeller 701 will not interfere with the wind collecting hood 107 during the rotation.

[0050] The ventilation pipe 106 shrinks from the end close to the air collecting cover 107 to the other end to form a variable diameter shape, and the ventilation pipe 106 bends from one end to the other end to form a folded shape.

[0051] The ventilation pipe 106 shrinks from the end close to the wind collecting cover 107 to the other end in a variable diameter shape to adjust the wind speed. When the diameter of the air inlet is larger than the air outlet, the air outlet space becomes smaller and the pressure increases, causing the wind speed to increase. At the same time, when the wind speed increases, the impact force of the wind is also greater, so as to rotate the protective shell 103.

[0052] The use process of the fire-fighting drone for rapid forest fire detection provided by the present invention is as follows:

[0053] When the drone is extended in flight, the wind energy generated by the drone propeller 701 is collected into the wind collecting hood 107 and enters the protective cover 102 along the ventilation duct 106. The collected wind energy blows the guide plate 104, and the blown guide plate 104 rotates. During the rotation, the solar cell panel 5 on the outer surface of the protective shell 103 is rotated. During the rotation, the solar cell panels 5 in multiple positions can be collected to improve its endurance. In addition, the generated wind energy can be used to generate electricity through the differential 301 and the generator 402 to achieve improved endurance on cloudy days.
