DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The following will be combined Figure 1-Figure 3 A protection device for high-voltage line inspection by an unmanned aerial vehicle in an embodiment of the utility model is described in detail.

[0022] Example:

[0023] The utility model provides a protection device for high-voltage line inspection by an unmanned aerial vehicle, referring to Figure 1 and Figure 2 As shown, it includes an inspection drone 1, a landing gear 11 is provided at the bottom of the inspection drone 1, and an inspection camera 17 is fixedly installed at the bottom of the mounting frame 17. This structure utilizes the inspection drone 1 to drive the inspection camera 17 on the landing gear 11 to move, thereby inspecting the high-voltage line and ensuring the safe use of the high-voltage line.

[0024] refer to Figure 1 and Figure 2As shown, a plurality of air distribution pipes 2 are fixedly connected to the landing gear 11, an air distribution seat 3 is fixedly connected to the inner ring of the air distribution pipe 2, a mounting frame 17 is fixedly connected to the landing gear 11, the air distribution seat 3 is fixedly installed on the mounting frame 17, an inflatable bottle 4 (the inflatable bottle 4 contains compressed carbon dioxide gas) is fixedly connected to the air distribution seat 3, a lower protective ring tube 5 is fixedly connected to the outer end of the air distribution pipe 2, a plurality of rubber airbags 1 6 are arranged on the outer wall of the lower protective ring tube 5, a vertical pipe 7 is fixedly connected to the lower protective ring tube 5, a rubber airbag 2 8 is arranged on the outer wall of the vertical pipe 7, an upper protective ring tube 9 is fixedly connected to the upper end of the vertical pipe 7, and a rubber airbag 3 10 is arranged on the outer wall of the upper protective ring tube 9, the inspection drone 1 is arranged in a frame composed of the lower protective ring tube 5, the vertical pipe 7 and the upper protective ring tube 9. When the inspection drone 1 with this structure flies normally, the frame structure composed of the lower protective ring tube 5, the vertical pipe 7 and the upper protective ring tube 9 can protect the flying inspection drone 1 and prevent the inspection drone 1 from being damaged when colliding with an object;

[0025] When the inspection unmanned frame 1 is out of control, the internal carbon dioxide is introduced into the gas distribution pipe 2 through the gas distribution seat 3 by using the gas filling bottle 4. The gas distribution pipe 2 will send part of the carbon dioxide into the lower protective ring tube 5, and the lower protective ring tube 5 will send the carbon dioxide into the upper protective ring tube 9 through the vertical pipe 7. At this time, the carbon dioxide gas will cause the rubber airbag 1 6 of the lower protective ring tube 5, the rubber airbag 2 8 of the vertical pipe 7 and the rubber airbag 3 10 of the upper protective ring tube 9 to inflate and collide. Therefore, when the inspection drone 1 loses control and falls, the rubber airbags 2 8 around the inspection drone 1 will provide 360-degree protection for the inspection drone 1, thereby preventing the main machine of the inspection drone 1 and its fan blade mechanism from being damaged. The 360-degree protection can better protect the inspection drone 1.

[0026] refer to Figure 2 As shown, a tilt angle sensor 12 and a single-chip control board 13 are fixedly installed on the landing gear 11. The specific model of the tilt angle sensor 12 is QJ626T. The tilt angle sensor 12 and the gas bottle 4 are electrically connected to the single-chip control board 13. This structure uses the tilt angle sensor 12 to detect the flight tilt angle of the inspection drone 1. When the inspection drone 1 is out of control, the tilt angle sensor 12 detects that the inspection drone 1 exceeds the controllable tilt angle, and then sends a signal to the single-chip control board 13. After receiving the signal, the single-chip control board 13 controls the gas bottle 4 to open, thereby realizing the inflation of the rubber airbag.

[0027] It should be noted that the control devices and programs between the tilt angle sensor 12, the single-chip control board 13 and the gas cylinder 4 in the above-mentioned structure are all prior art, the principles are public, and no improvement is made in this application, so no further introduction is given here.

[0028] refer to Figure 1 and 3As shown, a plurality of air outlet holes 14 are provided on the lower protective ring tube 5 , and the air outlet holes 14 are arranged in the rubber airbag 6 . This structure utilizes the air outlet holes 14 to allow the carbon dioxide in the inflation bottle 4 to enter the rubber airbag 6 .

[0029] refer to Figure 1 and 3 As shown, a plurality of air outlet holes 15 are provided on the vertical pipe 7 , and the air outlet holes 15 are arranged in the rubber airbag 8 . This structure utilizes the air outlet holes 15 to allow the carbon dioxide in the inflation bottle 4 to enter the rubber airbag 8 .

[0030] refer to Figure 1 and 3 As shown, the upper protective ring tube 9 is provided with a plurality of air outlet holes 3 16 , which are arranged in the rubber airbag 3 10 . This structure utilizes the air outlet holes 3 16 to allow the carbon dioxide in the gas bottle 4 to enter the rubber airbag 3 10 .

[0031] refer to Figure 1 As shown, the air distribution pipe 2, the air distribution seat 3, the lower protective ring pipe 5, the vertical pipe 7 and the upper protective ring pipe 9 are all made of aluminum alloy. The aluminum alloy of this structure is light in weight and high in strength, so that the inspection drone 1 will not be overloaded.

[0032] It should be noted that the above-mentioned inspection drone 1 is used for the inspection of high-voltage lines.

[0033] The implementation principle of the protection device for high-voltage line inspection of an unmanned aerial vehicle in the embodiment of the present application is as follows: when in use, the tilt angle sensor 12 detects the flight tilt angle of the inspection unmanned aerial vehicle 1. When the inspection unmanned aerial vehicle 1 is out of control, the tilt angle sensor 12 detects that the inspection unmanned aerial vehicle 1 exceeds the controllable tilt angle, and then sends a signal to the single-chip control board 13. After the single-chip control board 13 receives the signal, it controls the gas bottle 4 to open, and the gas bottle 4 allows the internal carbon dioxide to enter the gas distribution pipe 2 through the gas distribution seat 3, and the gas distribution pipe 2 will send part of the carbon dioxide into the lower protective ring pipe 5, the lower protection ring tube 5 will send carbon dioxide into the upper protection ring tube 9 through the vertical pipe 7. At this time, the carbon dioxide gas will inflate and collide with the rubber airbag 1 6 of the lower protection ring tube 5, the rubber airbag 2 8 of the vertical pipe 7 and the rubber airbag 3 10 of the upper protection ring tube 9. Therefore, when the inspection drone 1 loses control and falls, the rubber airbags 2 8 around the inspection drone 1 will provide 360-degree protection for the inspection drone 1, thereby preventing the main machine of the inspection drone 1 and its fan blade mechanism from being damaged. The 360-degree protection can better protect the inspection drone 1.
