The support plates are connected to the gears (22) through a transmission assembly. When the two support plates (3) are close together, the warning plate (2) is stored on the frame (1). When the two support plates (3) are far apart, the warning plate (2) is flipped relative to the frame for display.
[0009] Preferably, the two support plates are symmetrically distributed about the midpoint of the frame, and warning signs are provided on the warning plates.
[0010] Preferably, each of the support plates has a connecting shaft 2 fixedly installed at its upper end, and each connecting shaft 2 is rotatably installed at the bottom of the frame. The frame is provided with a cleaning component, which includes a motor and a cleaning pad. The surface of the warning plate has a groove, and a light strip is installed in the groove. A sliding groove is provided in the middle of the surface of the frame. The motor is fixedly installed at the upper end of the frame, and the output shaft of the motor is fixedly connected to a threaded rod, which is rotatably installed in the sliding groove.
[0011] Preferably, an L-plate is fixedly connected to the middle of the cleaning mat, and a second magnet block is fixedly connected to the L-plate. Limiting grooves are opened on both inner walls of the frame. The two ends of the L-plate are slidably installed in the limiting grooves. A soft brush is provided on the surface of the cleaning mat.

[0014] (III) Beneficial Effects
[0015] 1. By separating the two support plates and placing them at a certain angle next to the construction site, the horizontal support range can be expanded, increasing the contact area with the ground and thus improving the stability of the support. The rotation of gear four drives gear one to rotate, causing the warning plate to rotate around the connecting shaft one, rotating the warning plate 180 degrees so that the side with the warning sign and light strip faces outward to warn pedestrians. The device can automatically unfold the warning plate after the two support plates are separated. When not in use, the support plates can be closed together to automatically fold the warning plate, making it easy to store, saving space, facilitating transportation and storage, and reducing the risk of equipment damage.
[0016] Second: In the initial state, the two support plates are magnetically connected and fixed under the action of the magnet plate, and are distributed in a vertical state, which facilitates quick switching to the use state, is simple to operate, saves space, and is convenient to carry and store. When the device needs to be used, the two support plates are pried apart, and the support plates will rotate around the second connecting shaft. A set of limit blocks are fixedly installed at both ends of the frame. The two sets of limit blocks limit the rotation angle of the two support plates, so that the two support plates can stably support the device when placed on the ground. This ensures that the support plates can reach the preset optimal support angle each time they are unfolded, ensuring the consistency and reliability of the support effect.
[0017] Thirdly, when the two support plates are magnetically fixed, the position of the warning plate will be limited, so that the warning plate remains parallel to the frame, making it easy to carry and store. When the two support plates are pried open, the warning plate will rotate 180 degrees and unfold, allowing it to be put into use quickly. This device can unfold and retract quickly and accurately, and is simple and quick to operate, making it more convenient to use.
[0018] Fourth: When the warning board is rotated 180 degrees, the first magnet on the warning board will also rotate 180 degrees, so that the first magnet and the second magnet are attached to each other and magnetically fixed together, further supporting and fixing the warning board, greatly enhancing the stability of the warning board after it is rotated, making it less likely to shake or shift in the working state.

The frame 1 is U-shaped. A connecting shaft 21 is fixedly installed on the upper end of the warning plate 2, and the connecting shaft 21 is rotatably installed inside the frame 1. Gears 22 are fixedly installed on both ends of the warning plate 2. A support assembly is provided at the bottom of the frame 1, including two support plates 3. Magnet plates 33 are fixedly installed on the opposite ends of the two support plates 3. A connecting shaft 31 is fixedly installed on the upper end of each support plate 3, and each connecting shaft 31 is rotatably installed on the bottom of the frame 1. A cleaning assembly is provided on the frame 1, including a motor 4 and a cleaning pad 5. An opening is provided on the surface of the warning plate 2. The frame 1 has a groove with a light strip 6 installed inside. Two support plates 3 are symmetrically distributed about the midpoint of the frame 1. A warning sign is placed on the warning plate 2. A sliding groove 11 is opened in the middle of the surface of the frame 1. The motor 4 is fixedly installed at the upper end of the frame 1. The output shaft of the motor 4 is fixedly connected to a threaded rod 41, which is rotatably installed in the sliding groove 11. An L-plate 51 is fixedly connected to the middle of the cleaning pad 5. A magnet 52 is fixedly connected to the L-plate 51. Limit grooves 12 are opened on both inner walls of the frame 1. The two ends of the L-plate 51 are slidably installed in the limit grooves 12. A soft brush is provided on the surface of the cleaning pad 5. The L-plate 51 is slidably installed in the sliding groove 11. The threaded rod 41 passes through the L-plate 51 and is threadedly connected to the L-plate 51. The surface of the magnet 52 is opened. The warning plate 2 has a circular hole. A magnet 23 corresponding to the position of magnet 52 is fixedly connected to the back end of the warning plate 2. Two conductive posts 24 are provided on the back end of the warning plate 2, both of which are electrically connected to the LED strip 6. Contact blocks 7 are fixedly connected to both ends of the upper part of the frame 1, with the positions of the two contact blocks 7 corresponding to the positions of the two conductive posts 24. Rotary shafts 9 are rotatably mounted on both ends of the frame 1. Gear 31 and gear 42 are fixedly mounted on each shaft 9. Gear 22 is fixedly mounted on both ends of each connecting shaft 21. Every two adjacent gear 22 meshes with each other. The two gear 22s located at the rear mesh with gear 31 respectively. A synchronous belt 25 is fitted onto each gear 42 and gear 12. The back end of the frame 1... A power supply 8 is provided, with two wires 81 connected to two contact blocks 7. A set of limiting blocks 14 are fixedly installed on both sides of the bottom of the frame 1 to limit the movement of the support plates 3 after they are unfolded. A ash discharge port 13 is provided on the bottom surface of the frame 1. When the warning device is needed for power maintenance, the workers pry open the two support plates 3, placing them at a certain angle next to the work position. This expands the support range horizontally, increasing the contact area with the ground and improving the stability of the support. Prying open the two support plates 3 causes the connecting shaft 2 31 to rotate, which in turn drives the gear 2 32 to rotate, which in turn drives the gear 3 91 to rotate.The rotation of gear 3 (91) drives the rotation of shaft 9, which in turn drives gear 4 (92), which in turn drives gear 1 (22), causing the warning plate 2 to rotate around connecting shaft 1 (21). This causes the warning plate 2 to rotate 180 degrees, so that the side with the warning sign and light strip 6 faces outwards to warn pedestrians. The device automatically unfolds the warning plate 2 when the two support plates 3 are opened, and automatically folds it up when not in use, facilitating storage, saving space, and reducing the risk of damage. In the initial state, the two support plates 3 are magnetically connected and fixed by the magnet plate 33, arranged vertically for quick switching to the usage state. Simple to operate, space-saving, and easy to carry and store. When the device is needed, the two support plates 3 are pried open, and the support plates 3 will rotate around the connecting shaft 31. A set of limiting blocks 14 are fixedly installed at both ends of the frame 1, limiting the rotation angle of the two support plates 3. This ensures that the two support plates 3 can stably support the device when placed on the ground, achieving the preset optimal support angle each time they are unfolded, guaranteeing consistent and reliable support. When the two support plates 3 are magnetically fixed, they limit the position of the warning plate 2, keeping it parallel to the frame 1 for easy carrying and storage. When the two support plates 3 are pried open, the warning plate 2 rotates 180 degrees and unfolds. This device is quick and easy to use, capable of rapid and accurate deployment and retraction. Its operation is simple and convenient. When the warning plate 2 is rotated 180 degrees, the first magnet 23 on it also rotates 180 degrees, causing it to magnetically attach to the second magnet 52, further supporting and securing the warning plate 2. This significantly enhances the stability of the warning plate 2 after rotation, preventing it from shaking or shifting during operation. When the warning plate 2 is rotated 180 degrees, the two conductive posts 24 attach to the two contact blocks 7, forming a closed circuit. This allows the power supply 8 to power the light strip 6, causing it to emit light, making it more visible at night or in low-light environments. The purpose is to serve as a warning, improving the visibility and effectiveness of the warning. When the warning board 2 is unfolded, the light strip 6 automatically turns on. When the warning board 2 is folded back, the two conductive posts 24 no longer contact the contact block 7, the circuit is broken, and the light strip 6 automatically turns off. This eliminates the need for manual control of the light strip 6, simplifying the operation and improving convenience. When the warning board 2 is in the retracted state, the motor 4 is activated, causing the threaded rod 41 to rotate. The rotation of the threaded rod 41 drives the L-plate 51 to slide within the slide groove 11. The sliding of the L-plate 51 causes the cleaning pad 5 to slide, which in turn drives the soft brush to clean away impurities adhering to the surface of the warning board 2, which are then discharged from the ash discharge port 13, ensuring that the warning board 2 remains clean for the next use.Without affecting its normal function and appearance, it can automatically start the cleaning program when the warning panel 2 is in the storage state, eliminating the need for manual operation and saving manpower and time.
[0031] Working principle:
[0032] The first step involves the worker prying open the two support plates 3 when a warning device is needed for power maintenance. The two support plates 3 are placed at a certain angle next to the work site, expanding the horizontal support range and increasing the contact area with the ground, thus improving stability. Prying open the two support plates 3 causes the connecting shaft 2 31 to rotate. This rotation drives the gear 2 32, which in turn drives the gear 3 91, which in turn drives the rotating shaft 9, which in turn drives the gear 4 92, which in turn drives the gear 1 22. This causes the warning plate 2 to rotate around the connecting shaft 21, rotating 180 degrees so that the side with the warning sign and light strip 6 faces outwards to warn pedestrians. The device automatically unfolds the warning plate 2 after the two support plates 3 are pried open. When not in use, the support plates 3 can be closed together to automatically fold the warning plate 2, facilitating storage, saving space, 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 facilitates quick switching to the use state, is simple to operate, saves space, and is convenient to carry and store. When the device needs to be used, the two support plates 3 are pried apart, and the support plates 3 will rotate around the connecting shaft 31. A set of limiting blocks 14 are fixedly installed at both ends of the frame 1. The two sets of limiting blocks 14 limit the rotation angle of the two support plates 3 respectively, so that the two support plates 3 can stably support the device when placed on the ground, and 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] Third, when the two support plates 3 are magnetically fixed, the position of the warning plate 2 will be limited, so that the warning plate 2 and the frame 1 remain parallel, making it easy to carry and store. When the two support plates 3 are pried open, the warning plate 2 will be rotated 180 degrees and unfolded, so that it can be put into use quickly. The device can unfold and store quickly and accurately, and is simple and quick to operate, making it more convenient to use.
[0035] Fourth step: When the warning board 2 is rotated 180 degrees, the first magnet 23 on the warning board 2 will also be rotated 180 degrees, so that the first magnet 23 and the second magnet 52 are attached to each other, and the first magnet 23 and the second magnet 52 are magnetically attracted and fixed, further supporting and fixing the warning board 2, greatly enhancing the stability of the warning board 2 after it is rotated, so that it is not easy to shake or shift in the working state.
[0036] Fifth, after the warning board 2 is rotated 180 degrees, the two conductive posts 24 are brought into contact with the two contact blocks 7, forming a closed circuit. This allows the power supply 8 to supply power to the light strip 6, causing the light strip 6 to emit light. This makes the warning more conspicuous in the dark or in low-light environments, improving the visibility and effectiveness of the warning. When the warning board 2 is unfolded, the light strip 6 will automatically open. When the warning board 2 is folded back, the two conductive posts 24 will no longer be in contact with the contact blocks 7, the circuit will be broken, and the light strip 6 will automatically turn off. There is no need for manual control of the light strip 6, which simplifies the operation process and improves the convenience of work.
[0037] Step 6: When the warning board 2 is in the retracted state, start the motor 4 to rotate the threaded rod 41. The rotation of the threaded rod 41 drives the L-plate 51 to slide in the slide groove 11. 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 board 2 and discharge them from the dust discharge port 13. This ensures that the warning board 2 is clean for the next use and does not affect its normal function and appearance. The cleaning program can be started automatically when the warning board 2 is in the retracted state, without the need for manual operation, saving manpower and time.
[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
