A set of limit blocks 14 are fixedly installed at both ends of the frame 1. The two sets of limit blocks 14 respectively limit the rotation angle of the two support plates 3, so that the two support plates 3 placed on the ground can stably support the device, so that the support plates 3 can reach the preset optimal support angle each time they are unfolded, ensuring the consistency and reliability of the support effect.

When the warning plate 2 is in the storage state, the cleaning program can be automatically started without manual operation, saving manpower and time.

[0031] Working principle:

[0032] The first step is that when the warning device is needed for power maintenance construction, the staff will open the two support plates 3 so that the two support plates 3 are placed next to the construction position at a certain tilt angle, which can expand the support range in the horizontal direction and increase the contact area with the ground, thereby improving the stability of the support. When the two support plates 3 are opened, the connecting shaft 2 31 will rotate, and the rotation of the connecting shaft 2 31 will drive the gear 2 32 to rotate, and the gear 3 91 will rotate through the rotation of the gear 2 32, and the rotating shaft 9 will rotate through the rotation of the gear 3 91, and the gear 4 92 will rotate through the rotation of the rotating shaft 9, and the gear 1 22 will rotate through the rotation of the gear 4 92, so that the warning plate 2 rotates with the connecting shaft 1 21 as the axis, so that the warning plate 2 is turned over 180 degrees, so that the side with the warning slogan and the light strip 6 faces outward, which is used to warn passers-by. The device can automatically unfold the warning plate 2 after the two support plates 3 are opened, and when not in use, the support plates 3 can automatically fold the warning plate 2 after being combined, which is convenient for storage, saving space, convenient for transportation and storage, and reducing the risk of equipment damage.

[0033] In the second step, in the initial state, the two support plates 3 are magnetically connected and fixed under the action of the magnet plate 33, and are distributed in a vertical state, which is convenient for quick switching to the use state, simple operation, space saving, and convenient to carry and store. When the device needs to be used, the two support plates 3 are opened, and the support plates 3 will rotate with the connecting shaft 2 31 as the axis. A set of limit blocks 14 are fixedly installed at both ends of the frame 1. The two sets of limit blocks 14 respectively limit the rotation angle of the two support plates 3, so that the two support plates 3 can be placed on the ground to stably support the device, so that the support plates 3 can reach the preset optimal support angle each time they are unfolded, ensuring the consistency and reliability of the support effect;

[0034] In the third step, when the two support plates 3 are fixed by magnetic attraction, the position of the warning plate 2 is limited, so that the warning plate 2 is kept parallel to the frame 1, which is convenient for carrying and storage. When the two support plates 3 are broken apart, the warning plate 2 is turned 180 degrees and unfolded, and can be quickly put into use. The device can quickly and accurately unfold and store, and the operation is simple and fast, and it is more convenient to use;

[0035] In the fourth step, when the warning plate 2 is turned over 180 degrees, the magnet block 1 23 on the warning plate 2 is also turned over 180 degrees, so that the magnet block 1 23 fits with the magnet block 2 52, so that the magnet block 1 23 and the magnet block 2 52 are magnetically fixed, further supporting and fixing the warning plate 2, greatly enhancing the stability of the warning plate 2 after turning over, so that it is not easy to shake or shift in the working state;

[0036] In the fifth step, after the warning plate 2 is turned over 180 degrees, the two conductive posts 24 are fitted with the two contact blocks 7 to form a closed loop, so that the power supply 8 supplies power to the light strip 6, so that the light strip 6 emits light, which can serve as a more eye-catching warning at night or in a dimly lit environment, thereby improving the visibility and effectiveness of the warning. When the warning plate 2 is unfolded for use, the light strip 6 can be automatically turned on. When the warning plate 2 is folded and retracted, the two conductive posts 24 are no longer fitted with the contact blocks 7, the circuit is disconnected, and the light strip 6 is automatically turned off. There is no need to manually control the switch of the light strip 6, which simplifies the operation process and improves the convenience of work.

[0037] In the sixth step, when the warning plate 2 is in the storage state, start the motor 4 to rotate the threaded rod 41, and the rotation of the threaded rod 41 drives the L plate 51 to slide in the slide groove 11, and the sliding of the L plate 51 drives the cleaning pad 5 to slide. The sliding of the cleaning pad 5 will drive the soft brush to clean the impurities attached to the surface of the warning plate 2 and discharge them from the ash discharge port 13, ensuring that the warning plate 2 remains clean when used next time, without affecting its normal function and appearance. When the warning plate 2 is in the storage state, the cleaning program can be automatically started without manual operation, saving manpower and time.

[0038] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
