[0016] (1) By setting up a support column, support sleeve, connecting pipe, positioning rod, ejector spring, connecting block, paddle, slide groove and friction pad, after installation, the device can pull the two paddles at one end of the two connecting pipes respectively. The paddle drives the positioning rod to move to one side through the connecting block. After the positioning rod drives the friction pad to get away from the outside of the support column, the mounting cover can be pulled to adjust the height of the top warning light.

While the threaded rod rotates inside the threaded sleeve, it can push the cone head to insert into the ground, thereby cooperating with the positioning cone to position and support the device, thus realizing the rapid installation and positioning of the device.

[0027] The friction pad 22 is movably connected to the support column 8, and the support column 8 is movably connected to the support sleeve 9;

[0028] The connecting pipe 16 is connected to the inside of the support sleeve 9, and the positioning rod 17 is slidably connected to the connecting pipe 16;

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, after installation, the device can pull the two sets of levers 20 at one end of the two sets of connecting pipes 16 respectively. The levers 20 drive the positioning rod 17 to move to one side through the connecting block 19. After the positioning rod 17 drives the friction pad 22 to detach from the outside of the support column 8, the mounting cover 1 can be pulled to adjust the height of the top warning light. After the height is appropriate, the levers 20 are released, and the ejection spring 18 inside the connecting pipe 16 can push the positioning rod 17 out. The positioning rod 17 pushes the friction pad 22 to fit against the outside of the support column 8. The top structure can be positioned by the support column 8, realizing the ability to quickly adjust the height of the structure.

[0030] The top of the mounting cover 1 is movably connected to the mounting plate 2, the top of the mounting plate 2 is fixedly connected to the battery compartment 3, the top of the battery compartment 3 is fixedly connected to the warning light holder 4, the two sides of the warning light holder 4 are fixedly connected to the lamp cover 5, the top of the inside of the mounting cover 1 is fixedly connected to the reducer 6, and the bottom of the reducer 6 is fixedly connected to the drive motor 7.

[0031] The output end of the drive motor 7 is fixedly connected to the input end of the reducer 6, and the output end of the reducer 6 passes through the top of the mounting cover 1 and is fixedly connected to the mounting plate 2.

[0032] The center line of mounting plate 2 and the center line of mounting cover 1 are on the same vertical plane, and the center line of warning light holder 4 and the center line of mounting plate 2 are on the same vertical plane;

[0033] Specifically, such as Figure 1 As shown, when the device is started, the warning light holder 4 first powers the lamp cores inside the two sets of lamp covers 5 through the battery compartment 3. After the lamp cores on both sides are turned on, they emit light simultaneously. At the same time, the drive motor 7 at the bottom is started and drives the mounting plate 2 at the top to rotate through the reducer 6. The mounting plate 2 then drives the light-emitting structure at the top to rotate, thereby driving the lamp cores inside the two sets of lamp covers 5 to rotate continuously.

[0037] Working Principle: When using this utility model, during installation, the positioning cone 13 at the bottom of the base plate 11 is first inserted into the sand and gravel surrounding the coal mining area, allowing the base plate 11 to adhere to the ground. Then, each set of rotating wheels 10 is rotated, causing the threaded rod 12 at the bottom to rotate. As the threaded rod 12 rotates inside the threaded sleeve 15, it pushes the cone 14 into the ground, thus cooperating with the positioning cone 13 to position and support the device. After installation, the device can pull on the two sets of levers 20 at one end of the two sets of connecting pipes 16. The levers 20, through the connecting block 19, drive the positioning rod 17 to one side.

Once the height is appropriate, release the lever 20. The ejector spring 18 inside the connecting tube 16 can eject the positioning rod 17. The positioning rod 17 pushes the friction pad 22 to fit against the outside of the support column 8. The top structure can be positioned by the support column 8. When the device is started, the warning light base 4 is activated first to supply power to the lamp cores inside the two sets of lamp covers 5 through the battery compartment 3. After the lamp cores on both sides are turned on, they emit light at the same time. At the same time, the drive motor 7 at the bottom is started and drives the mounting plate 2 at the top to rotate through the reducer 6. The mounting plate 2 then drives the top light-emitting structure to rotate, thereby driving the lamp cores inside the two sets of lamp covers 5 to rotate continuously. The rotation of the two sets of lamp cores can emit dynamic warning lights to improve the warning effect.
