referring to fig. 1-7, substantially the same as embodiment 1, further, an adjustable billboard with a windproof function includes a base 1 and a mounting frame 2 fixedly connected to the base 1, the mounting frame 2 is provided with the billboard, the billboard is composed of modules 4, the modules 4 are rotatably connected in the mounting frame 2, the mounting frame 2 is provided with a turnover mechanism for rotating the modules 4, the base 1 is provided with a stabilizing mechanism, and the stabilizing mechanism is provided with a brushing mechanism.

The wind blowing turning plate 5 rotates to enable the turning plate 5 to extrude the pressing rod 603 to move downwards, so that the inclined rod 601 slides towards the installation block 6011, the first rack 6012 slides, the first rotating shaft 604 rotates, the second gear 6042 at the bottom of the first rotating shaft 604 drives the second rack 301 to slide, the module 4 is turned over when the second rack 301 slides to drive the third gear 401 to rotate, the fourth gear 402 drives the third rack 1011 to extend when the module 4 is turned over, so that the supporting plate 101 extends out and improves the stability, the threaded cylinder 102 rotates to drive the one-way rotating cylinder 1021 to rotate in the retracting process of the supporting plate 101, the forward and reverse rotation alternate rotation of the second rotating shaft 103 is realized through the intermittent meshing of the first half gear 104 and the sixth gear 104 and the intermittent meshing of the second half gear 1023 and the fifth gear 1031, the brush block 203 slides up and down to clean the module 4, and the water spraying pipe 2012 starts to spray water towards the module 4 when the brush block 203 rises, the cleaning effect is improved.

The working principle is as follows: in the invention, when the wind power is too large, the turning plate 5 is blown to rotate, at the same time, the turning plate 5 extrudes the pressing rod 603 downwards, so that the transverse block 6 fixedly connected to the bottom of the pressing rod 603 moves downwards, at the same time, the inclined rod 601 fixedly connected to the transverse block 6 slides towards the inside of the mounting block 6011, at the same time, the mounting block 6011 slides towards the direction of the first gear 6041, so that the first rack 6012 slides, at the same time, the first gear 6041 meshed with the first rack 6012 rotates, so that the first rotating shaft 604 rotates, the second gear 6042 fixedly connected to the bottom of the first rotating shaft 604 rotates, at the same time, the second rack 301 meshed with the second gear 6042 slides, so that the third gear 401 meshed with the second rack 301 rotates, at the same time, the module 4 rotates, so that the whole area of the module 4 blown by the wind is reduced, so that the stress of the advertising board is reduced, and when the module 4 rotates, the fourth gear 402 fixedly connected to the bottom of the module 4 rotates, at this time, the third rack 1011 engaged with the fourth gear 402 slides, so that the third rack 1011 extends from the base 1, and the support plate 1011 fixedly connected to the third rack 1011 extends, at this time, the stability of the base 1 is lifted, when the support plate 101 moves outwards, the threaded rod 1012 fixedly connected to the support plate 101 also slides outwards, at this time, the threaded cylinder 102 screwed to the threaded rod 1012 rotates, the one-way rotating cylinder 1021 rotates on the threaded cylinder 102 in one-way, the one-way rotating cylinder 1021 does not rotate along with the threaded cylinder 102 during the process of withdrawing the threaded rod 1012 from the threaded cylinder 102, when the wind force is reduced, the elastic force of the first spring 6021 is greater than the wind force, at this time, the inclined rod 601 is withdrawn from the mounting block 6011, so that the module 4 rotates to the home position, at this time, the support plate 101 retracts, so that the threaded rod 1012 slides into the threaded cylinder 102, because the cylindrical rod 1013 is connected to the threaded rod 1012, so that when the module 4 is not turned to be flat, the threaded rod 1012 is not in contact with the threads on the threaded cylinder 102, the threaded cylinder 102 is not rotated, when the module 4 is turned to be flat, the threads on the threaded rod 1012 are in contact with the threads on the threaded cylinder 102, the threaded cylinder 102 is rotated, the one-way drum 1021 rotates along with the threaded cylinder 102, the first half gear 1022 and the second half gear 1023 are also rotated, the sixth gear 104 is driven to rotate when the first half gear 1022 is meshed with the sixth gear 104, the sixth gear 104 is meshed with the fifth gear 1031, so that the fifth gear 1031 rotates, so that the second rotating shaft 103 rotates, the link 1032 fixedly connected to the second rotating shaft 103 swings upward, so that the brush block 203 is pushed to slide upward, when the second half gear 103 is meshed with the fifth gear 1031, the rotation direction of the second rotating shaft 103 is adjusted, so that the link 1032 swings downward, so that the brush block 203 slides downward, thereby make brush piece 203 return the original position, do not influence the upset of module 4, push pedal 2031 on the brush piece 203 just can promote piston rod 202 when brush piece 203 upward movement, piston plate 2021 upwards slides in water tank 201 this moment, thereby water in the water tank 1 sprays to module 4 on through spray pipe 2012, cooperation brush piece 203 reciprocates and cleans module 4, promote clean effect, just can add water in water tank 2 through opening chamber door 2011 when water in the water tank 201 is not enough, warning board 501 is ninety degrees with turning over 5 contained angles, thereby warning board 501 upset is vertical state when wind-force is too big, pressure sensitive switch 5011 on the warning board 501 contacts trigger plate 5012 this moment, thereby the LED lamp on the warning board 501 is luminous, play the warning effect.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
