Two rotating gears 78, a motor 79 installed on the surface of one side of one of the fixed plates 71 away from the screw 73 and used to drive the two gears 78 to rotate, the two gears 78 are meshed with each other, and the connecting rod 74 is slidably connected to the top surface of the mounting plate 2. By setting the bottom plate 1, a plurality of plug rods 5, two lifting mechanisms 6, the mounting plate 2 mounting frame 3 and the warning sign 4, it can serve as a warning for people entering the forest. By setting the cleaning mechanism 7, the fallen leaves or other debris attached to the front surface of the warning sign 4 can be cleaned to prevent the fallen leaves or other debris attached to the front surface of the warning sign 4 from affecting the normal warning work of the warning sign 4.

[0031] In this embodiment, the cleaning mechanism 7 also includes a rotating shaft 710 coaxially connected to the output shaft of the motor 79, and two gears 78 are coaxially fixed on the circumferential outer walls of the rotating shaft 710 and the rotating rod 77, respectively, which can smoothly drive the two gears 78 to rotate, and then smoothly drive the screw 73 to rotate.

[0032] In addition, a guide groove is provided on the top surface of the mounting plate 2, and a guide block 76 is fixed on the bottom surface of the vertical rod end of the connecting rod 74 and is slidably connected to the guide groove on the top surface of the mounting plate 2, which can guide the movement of the connecting rod 74 and further guide the movement of several brush rods 75.

[0033] Furthermore, the lifting mechanism 6 includes a sleeve 61 fixed on the top surface of the base plate 1, a telescopic rod 62 fixed on the bottom surface of the mounting plate 2 and slidably plugged with the sleeve 61, and a mounting hole connected to its inner cavity is provided near the top of the front surface of the sleeve 61. The lifting mechanism 6 also includes a fastening screw 63 threadedly connected to the mounting hole on the front surface of the sleeve 61, and the rear surface of the fastening screw 63 is tightly in contact with the front surface of the telescopic rod 62 on the same side, so that the height of the mounting plate 2 can be adjusted, and then the height of the warning sign 4 can be adjusted.

[0034] Specifically, handles 8 are fixed near the middle position of the left and right side surfaces of the mounting plate 2, and the handles 8 are U-shaped, so that the entire device can be easily taken and placed.

[0035] More specifically, the brush rod 75 corresponds to the position of the warning sign 4 and is of a similar size to the warning sign 4 , and the rear surface of the brush rod 75 and the front surface of the warning sign 4 are located on the same plane, so that several brush rods 75 can smoothly clean the front surface of the warning sign 4 .

[0036] It is worth noting that the cleaning mechanism 7 also includes a protective box 711 fixed on the surface of one of the fixed plates 71 away from the screw 73, the motor 79 is located inside the protective box 711, and the rotating shaft 710 passes through the outer wall of the protective box 711 away from the screw 73, which can protect the motor 79 and thus extend the service life of the motor 79.

[0037] It is worth mentioning that the longitudinal cross-sectional shape of the guide groove on the top surface of the mounting plate 2 is a convex shape, and the shape of the guide block 76 is a convex shape that matches the shape of the guide groove on the top surface of the mounting plate 2, which can make the connection between the guide block 76 and the guide groove on the top surface of the mounting plate 2 tighter, and indirectly make the several brush rods 75 more stable during the movement.

[0038] It is worth emphasizing that the distance between the protection box 711 and the gear 78 on the same side is 3-11 cm, and the distance between the protection box 711 and the rotating rod 77 is 2-9 cm. In this article, the distance between the protection box 711 and the gear 78 on the same side is preferably 10 cm, and the distance between the protection box 711 and the rotating rod 77 is preferably 8 cm, so that the rotation of the two gears 78 and the rotating rod 77 can be unimpeded.

[0039] Among them, the motor 79 involved in this embodiment is a prior art, and its structure and working principle are well known to those skilled in the art, and will not be described in detail here.

[0040] In the specific use of this embodiment, after the warning sign 4 has been used for a period of time, the output shaft of the motor 79 is started and controlled by the external PLC to rotate alternately in forward and reverse directions. The rotation of the output shaft of the motor 79 drives the rotating shaft 710 coaxially connected thereto to rotate. The rotation of the rotating shaft 710 drives the coaxially fixed gear 78 on the same side to rotate. The rotation of the gear 78 drives another gear 78 meshing therewith to rotate. The rotation of the other gear 78 drives the rotating rod 77 coaxially fixed thereto to rotate. The rotation of the rotating rod 77 drives the coaxially fixed rotating column 72 on the same side to rotate. The rotation of the rotating column 72 drives the coaxially fixed screw 73 to rotate. The rotation of 73 drives the connecting rod 74 threadedly connected thereto to move, and the connecting rod 74 moves under the guidance of the guide block 76 and the guide groove on the top surface of the mounting plate 2. The movement of the connecting rod 74 drives the movement of several brush rods 75 fixed thereto. Because the output shaft of the motor 79 rotates alternately forward and reverse, the connecting rod 74 can be indirectly driven to make a linear reciprocating motion in the horizontal direction, thereby driving several brush rods 75 to make a linear reciprocating motion in the horizontal direction. In the process of the linear reciprocating motion of several brush rods 75 in the horizontal direction, the fallen leaves or other debris attached to the front surface of the warning sign 4 can be cleaned.

[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
