[0026] Embodiment 1

[0027] AsFigure 1-6 As shown in the figure, this is the first embodiment of the present utility model. This embodiment provides a drone protection device used in a mine roadway, including a base 1, a lower protective cover 2, and an upper protective cover 3. The top of the base 1 is fixedly connected to the lower protective cover 2, and the upper protective cover 3 is fixedly installed on the top of the lower protective cover 2.

[0028] As Figure 1 、 Figure 2 shown, press the first rubber strip 206 into the inner cavity of the first installation groove 204. A part of the first rubber strip 206 is clamped inside the first installation groove 204 and is in close contact with one end of the first support spring 205, and the other part remains outside the first arc-shaped connecting arm 202 and contacts the outside during a collision.

[0029] Embodiment 2

[0030] Referring to Figure 3 、 Figure 4 , this is the second embodiment of the present utility model. This embodiment is based on the previous embodiment.

[0031] In this embodiment, the base 1 includes a fixed block 101, a limit groove 102, a through hole 103, a card slot 104, a hoop 105, a gasket 106, and a rotating rod 107. The fixed block 101 is fixedly installed at the end of the drone arm. The limit groove 102 is opened on the top of the fixed block 101. The through hole 103 is opened on the outer surface of the fixed block 101. The card slot 104 is arranged on the front of the fixed block 101. The hoop 105 is fixedly installed on the top of the card slot 104. The gasket 106 is fixedly installed on the inner surface of the hoop 105. The hoop 105 is fixedly connected to the fixed block 101 through the rotating rod 107. The bottom of the base 1 is fixedly connected to a support leg 4. One side of the lower protective cover 2 is fixedly connected to a plugging rod 5, and the other side of the lower protective cover 2 is fixedly connected to a plugging cylinder 6. The plugging rod 5 and the plugging cylinder 6 are adapted to each other.

[0032] As Figure 3 、 Figure 4As shown, by inserting and fixing the insertion rod 5 and the insertion cylinder 6, four lower protective covers 2 can be assembled into a whole, improving the overall stability of the protection device. At the same time, by disassembling, the space occupied by the protection device can be reduced, facilitating the overall storage of the protection device and improving its practicability and convenience.

[0033] Embodiment 3

[0034] Refer to Figure 5 、 Figure 6 , which is the third embodiment of the present utility model. This embodiment is based on the first two embodiments.

[0035] In this embodiment, the upper protective cover 3 includes a second connecting rod 301, a second arc-shaped connecting arm 302, a second reinforcing rib 303, a second installation groove 304, a second support spring 305, and a second rubber strip 306. The second arc-shaped connecting arm 302 is fixedly connected to the bottom of the second connecting rod 301. The second reinforcing rib 303 is fixedly connected to the top of the second arc-shaped connecting arm 302. The second installation groove 304 is opened on the outer side of the second arc-shaped connecting arm 302. A plurality of second support springs 305 are evenly and fixedly connected to the inner wall of the second installation groove 304. One side of the second rubber strip 306 is fixedly installed inside the second installation groove 304 and is connected to the second support spring 305. A slot 7 is opened at the top of the lower protective cover 2. A plug rod 8 is fixedly connected to the bottom of the upper protective cover 3. The slot 7 is adapted to the plug rod 8. An anti-corrosion coating 9 is provided inside the first arc-shaped connecting arm 202 and the second arc-shaped connecting arm 302. A wear-resistant coating 10 is provided on the outer side of the anti-corrosion coating 9. A heat-insulating coating 11 is provided on the wear-resistant coating 10. A fluorescent coating 12 is provided on the outer side of the heat-insulating coating 11.

[0036] As Figure 5 、 Figure 6 shown, by inserting the plug rod 8 into the slot 7, the upper protective cover 3 and the lower protective cover 2 can be assembled together to provide a full-enclosure protection for the propeller of the drone, isolating the propeller from the outside world in all directions, preventing falling rocks from the top in the mine roadway from damaging the drone, and improving the flight safety.

[0037] In use, first connect the four lower protective covers 2 through the adjacent insertion rods 5 and insertion cylinders 6 to form a protective frame for the lower half of the propeller. Then align the end of the drone arm with the slot position of the limit slot 102 and press it down into the limit slot 102. Rotate the hoop 105 to bind the arm. Next, connect the four upper protective covers 3 through the adjacent insertion rods 5 and insertion cylinders 6. Then align the insertion rod 8 at the bottom of the upper protective cover 3 with the slot 7 on the lower protective cover 2 and press and fix it to connect the lower protective cover 2 and the upper protective cover 3 into an integral frame. If the drone collides during flight, the outermost rubber strip first contacts the impact point. The rubber strip is squeezed inward by the impact to compress the support spring, reducing and dispersing the impact force. The anti-corrosion coating 9 applied to the outside of the connecting arm can help the protective cover resist corrosion and extend the service life of the protection device. The wear-resistant coating 10 can increase the surface hardness of the protection device, reducing friction and wear. The heat-insulating coating 11 emits heat, reducing the impact of the high-temperature environment in the mine on the structure. The fluorescent coating 12 makes the protection device visible to a certain extent in the mine roadway with low light environment, facilitating the monitoring and operation of the drone by the staff.

[0038] It is important to note that the construction and arrangement of the present application shown in multiple different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who refer to this disclosure should easily understand that many modifications are possible without substantially departing from the novel teachings and advantages of the subject matter described in this application (for example, the dimensions, scales, structures, shapes and proportions of various elements, and parameter values (such as temperature, pressure, etc.), installation arrangements, use of materials, color, orientation changes, etc.).
