The first end of the first transmission slot 207 is rotated by the second end of the second transmission slot 207, and the second end of the second transmission slot 207 is rotated by the second end of the second transmission slot 207.

[0047] It is worth noting that there are two anti-bird droppings mechanisms. When activated, the two slides 202 extend from the front and rear sides of the sign body 1 respectively to prevent both sides of the sign body 1 from being contaminated with bird droppings.

[0048] Reference Figure 1-10 The expulsion mechanism includes a lifting groove 401, a lifting frame 402 and a rotating shaft 403. The lifting groove 401 is opened at the top of the card body 1, the lifting frame 402 is slidably installed in the lifting groove 401, and the rotating shaft 403 is rotatably installed on the inner wall of the lifting frame 402. The height of the top of the rotating shaft 403 is higher than the height of the top of the card body 1. By setting the expulsion mechanism, when the bird falls on the top of the card body 1, since the height of the top of the rotating shaft 403 is higher than the height of the top of the card body 1, the bird falls on the top of the rotating shaft 403. Through the gravity of the bird itself, the rotating shaft 403 drives the lifting frame 402 to slide downward in the lifting groove 401 until it reaches a preset position, causing the rotating shaft 403 to rotate, so that the bird cannot stay on the rotating shaft 403 and is expelled;

[0049] Reference Figure 1-10 The rainproof mechanism includes a rainproof plate 501 and an adjusting plate 502. The rainproof plate 501 is rotatably mounted on the surface of one of the slides 202 through a hinge. The shape of the side cross-section of the rainproof plate 501 is set to be inclined. The adjusting plate 502 is slidably mounted inside the slide 202. The top of the adjusting plate 502 is in contact with the bottom of the rainproof plate 501. By setting the rainproof mechanism, when it rains, the front side of the sign body 1 is shielded by the rainproof plate 501 to prevent the front side of the sign body 1 displaying fonts and patterns from being soaked by rain for a long time, thereby damaging the electronic screen. Since the rainproof plate 501 is rotatably mounted on the slide 202 through a hinge, and the top of the adjusting plate 502 is in contact with the bottom of the rainproof plate 501, when the rain is heavy, the adjusting plate 502 is moved forward so that the angle of the rainproof plate 501 can be adjusted to improve the shielding effect.

[0050] Reference Figure 1-10 , a second transmission groove 6 is opened on the surface of the rotating rod 3, and the shapes of the first transmission groove 204 and the second transmission groove 6 are both set to a straight notch shape. A second transmission shaft 7 is fixedly installed on the surface of the lifting frame 402, and the second transmission shaft 7 is slidably sleeved inside the second transmission groove 6. A lifting spring 8 is fixedly installed on the bottom of the inner wall of the lifting groove 401, and the other end of the lifting spring 8 is fixedly connected to the bottom of the lifting frame 402. Gears 9 are fixedly installed on the left and right sides of the rotating shaft 403, and meshing teeth 10 are fixedly installed on the front side of the inner wall of the lifting groove 401. By setting the second transmission shaft 7 and the first When a bird lands on the rotating shaft 403, the rotating shaft 403 drives the lifting frame 402 to move downward, thereby causing the second transmission shaft 7 to move downward. The second transmission shaft 7 squeezes the inner wall of the second transmission groove 6, causing the two second transmission grooves 6 to drive the two rotating rods 3 to rotate in opposite directions, thereby causing the slide 202 to protrude from the interior of the slide groove 201. When the lifting frame 402 moves to the preset position, the gear 9 engages with the meshing teeth 10, causing the gear 9 to drive the rotating shaft 403 to rotate, preventing the bird from staying on the rotating shaft 403.

[0051] Reference Figure 1-10, a movable chamber 11 is provided on the top of the card body 1, and a receiving box 12 is slidably installed inside the movable chamber 11. The top of the receiving box 12 is opened, and a plug rod 13 is fixedly installed on the bottom of the receiving box 12. A plug slot 14 is provided on the top of the receiving box 203, and the plug slot 14 is located below the plug rod 13. A movable spring 15 is fixedly installed on the bottom of the inner wall of the movable chamber 11, and the other end of the movable spring 15 is fixedly connected to the receiving box 12. A first water outlet 16 is provided on the front side of the receiving box 12, and a receiving block 17 is fixedly installed on the front side of the slide 202. A receiving chamber 18 is provided inside the slide 202, and the receiving box 203 is slidably arranged inside the receiving chamber 18. A receiving spring 19 is fixedly installed on the rear side of the inner wall of the receiving chamber 18, and the other end of the receiving spring 19 is fixedly connected to the receiving box 203. By setting the receiving chamber 18 When it rains, since the top of the receiving box 12 is open, after rainwater falls into the receiving box 12, the moving spring 15 is squeezed due to the increase in the overall weight, and the receiving box 12 drives the plugging rod 13 to move downward. Since the plugging rod 13 is located above the plugging slot 14, the plugging rod 13 is inserted into the plugging slot 14, thereby fixing the receiving box 203 in position. As the rainwater inside the receiving box 12 increases, the receiving box 12 continues to move downward, squeezing the receiving block 17, so that the receiving block 17 drives the lifting frame 402 to move downward, so that the slide 202 moves outward from the inside of the slide slot 201. Since the position of the receiving box 203 is fixed at this time, the receiving box 203 enters the inside of the receiving chamber 18, preventing rainwater from entering the inside of the receiving box 203 and mixing with the bird droppings;

[0052] Reference Figure 1-10, a compression chamber 20 is provided inside the slide 202, a compression plate 21 is slidably installed inside the compression chamber 20, the bottom of the compression plate 21 is opened, a direction-changing groove 22 is provided inside the compression plate 21, a direction-changing shaft 23 is provided on the sliding sleeve of the direction-changing groove 22, a direction-changing plate 24 is fixedly provided on the surface of the direction-changing shaft 23, the bottom of the direction-changing plate 24 is fixedly connected to the top of the adjustment plate 502, a compression spring 25 and a telescopic rod 26 are installed at the bottom of the compression plate 21, and the other ends of the compression spring 25 and the telescopic rod 26 are fixedly connected to the bottom of the compression chamber 20. By setting the compression chamber 20 and the compression plate 21, when the slide 202 is out of the slide groove 20 1, and when the accommodating box 203 is retracted into the accommodating chamber 18, rainwater falls onto the compression plate 21. As the amount of rainwater on the compression plate 21 increases, the compression plate 21 moves downward, squeezing the compression spring 25, causing the direction-changing groove 22 to squeeze the direction-changing shaft 23, thereby causing the direction-changing shaft 23 to drive the direction-changing plate 24 to move toward the side close to the rainproof plate 501. Through the connection between the direction-changing plate 24 and the adjustment plate 502, the adjustment plate 502 is driven to move toward the side close to the rainproof plate 501 and squeeze the rainproof plate 501, so that the angle of the rainproof plate 501 is automatically adjusted as the compression plate 21 moves downward.

[0053] Reference Figure 1-10 A second water outlet 27 is provided on the front side of the slide 202. There are multiple second water outlet holes 27, which are arranged in a rectangular array. By setting the second water outlet holes 27, when rainwater falls on the compression plate 21, it is discharged outward through the second water outlet holes 27 at the same time. As the amount of rainwater increases, the second water outlet holes 27 are unable to drain the water outward in time, which increases the pressure of the rainwater on the compression plate 21, causing the compression plate 21 to move downward until it reaches the position of the second row of second water outlet holes 27. Due to the increase in the number of second water outlet holes 27, the drainage volume becomes larger, and so on, so that the descending distance of the compression plate 21 increases with the increase in rainfall.

[0054] Specifically, the working process or working principle of this electronic information sign is as follows: when in use, when the bird falls on the top of the sign body 1, since the height of the top of the rotating shaft 403 is higher than the height of the top of the sign body 1, the bird falls on the top of the rotating shaft 403, and through the gravity of the bird itself, the rotating shaft 403 drives the lifting frame 402 to slide downward inside the lifting groove 401, thereby causing the second transmission shaft 7 to move downward, and the second transmission shaft 7 squeezes the inner wall of the second transmission groove 6, so that the two second transmission grooves 6 drive the two rotating rods 3 to rotate in opposite directions. Since the center points of the two rotating rods 3 coincide and the two rotating rods 3 are cross-arranged, the center points of the two rotating rods 3 are fixed inside the sign body 1 through the rotating shaft, so that the two rotating rods 3 rotates and moves away from each other, causing the first transmission shaft 205 to squeeze the inner wall of the first transmission groove 204, and through the cooperation of the slide 201, the two slides 202 move in opposite directions. The end face of the slide 202 in the initial position is flush with the end face of the card body 1. After disengaging from the inside of the slide 201, the receiving box 203 is also disengaged. When birds defecate on the top of the card body 1, they fall into the inside of the receiving box 203 to prevent bird droppings from falling onto the surface of the card body 1. When the lifting frame 402 moves to the preset position, the gear 9 engages with the meshing teeth 10, so that the gear 9 drives the rotating shaft 403 to rotate, so that the birds cannot stay on the rotating shaft 403. When it rains, since the top of the receiving box 12 is open, When rainwater falls into the interior of the receiving box 12, the overall weight increases, which squeezes the moving spring 15, and the receiving box 12 drives the plug rod 13 to move downward. Since the plug rod 13 is located above the plug slot 14, the plug rod 13 is inserted into the plug slot 14, thereby fixing the receiving box 203 in position. As the rainwater inside the receiving box 12 increases, the receiving box 12 continues to move downward, squeezing the receiving block 17, so that the receiving block 17 drives the lifting frame 402 to move downward, so that the slide 202 moves outward from the inside of the slide slot 201. Since the position of the receiving box 203 is fixed at this time, the receiving box 203 enters the interior of the receiving cavity 18, preventing rainwater from entering the receiving box 203. The rainwater mixes with the bird droppings inside, and then falls onto the compression plate 21 and is discharged outwardly through the second water outlet 27. As the amount of rainwater increases, the second water outlet 27 has no time to drain the water outwardly. As the amount of rainwater on the compression plate 21 increases, the compression plate 21 moves downward, squeezing the compression spring 25, causing the changing groove 22 to squeeze the changing shaft 23, thereby causing the changing shaft 23 to drive the changing plate 24 to move toward the side close to the rainproof plate 501. Through the connection relationship between the changing plate 24 and the adjusting plate 502, the adjusting plate 502 is driven to move toward the side close to the rainproof plate 501 and squeeze the rainproof plate 501, so that the angle of the rainproof plate 501 is automatically adjusted as the compression plate 21 moves downward.
