[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] Example 1: As Figures 1 to 10 As shown in the figure, a bridge-culvert structure for facilitating the passage of wild animals according to an embodiment of the present invention includes a bridge 1, and a culvert 2 is provided at the bottom of the bridge 1; a plurality of hydraulic rods 3 are fixedly installed on the top of the inner wall of the culvert 2, a connecting frame 4 is fixedly installed on the bottom of the hydraulic rods 3, a connecting groove 5 is provided on one side of the connecting frame 4, a water level sensor 7 is fixedly installed on the side wall of the culvert 2, a controller is fixedly installed on the top of the culvert 2, and two symmetrically arranged baffles 6 are fixedly installed on the inner wall of the culvert 2, the side of the baffles 6 away from the connecting frame 4 is arc-shaped;

[0034] Bridge 1 with culvert 2 is mostly built in the wild, and there are more wild animals in the wild. When wild animals need to migrate during the plum rain season, they need to pass through the culvert 2. The bridge 1 with the culvert 2 is mostly built in a terrain with high sides and a low middle position of the culvert 2. At this time, there is a large amount of water in the culvert 2, and larger wild animals can wade through the culvert 2, but smaller wild animals may have difficulty passing through the culvert 2. When the plum rain season comes, rainwater will flow into the culvert 2, and the water level in the culvert 2 will slowly rise. At this time, the water level sensor 7 will monitor the rising water level in the culvert 2 and transmit the monitored information to the controller. When the water level reaches a certain value, the controller starts the hydraulic rod 3, so that the output end of the hydraulic rod 3 moves downward with the connecting frame 4. The controller can adjust the height of the connecting frame 4 according to the actual height of the water level, so that the connecting frame 4 is always located on the water surface, thereby facilitating the wild animals to pass through the culvert 2 through the connecting groove 5. When the water level decreases to a certain value, the controller resets the connecting frame 4 to the top of the culvert 2 through the hydraulic rod 3. By arranging the baffle 6, when the water level in the culvert 2 is high, the connecting frame 4 is located at the top of the culvert 2, and water may enter the connecting groove 5, causing the connecting groove 5 to be blocked. The two baffles 6 are arranged at the port of the connecting groove 5, thereby effectively blocking rainwater and impurities from entering the connecting groove 5. At the same time, one side of the baffle 6 is arc-shaped to better guide the rainwater, facilitating the rainwater and impurities to pass through the culvert 2.

[0035] The bottom of the baffle 6 is fixedly provided with an arc-shaped guide plate 10, both ends of the connecting frame 4 are provided with a groove 8, the inner wall of the groove 8 is slidably connected with an extension plate 9 through a spring, and the top of the extension plate 9 is arc-shaped. When the connecting frame 4 moves downward, the extension plate 9 in the groove 8 is no longer in contact with the guide plate 10 at the bottom of the baffle 6, at this time, the spring in the groove 8 slides the extension plate 9 away from the groove 8, thereby extending the extension plate 9. At this time, the wild animals can enter the connecting groove 5 through the extended extension plate 9. The extension plate 9 plays a role in reducing the height of entering the connecting groove 5. At the same time, the surface of the extension plate 9 is of anti-skid material, so it is more convenient for wild animals to enter. When the connecting frame 4 is reset, the arc-shaped extension plate 9 is in contact with the arc-shaped guide plate 10. The extension plate 9 slides into the groove 8 under the extrusion of the guide plate 10, thereby allowing the baffle 6 to be shielded in front of the extension plate 9, thereby protecting the connecting frame 4 and the connecting groove 5.

[0037] The scraper 14 is slidingly connected with a breaking rod 15 through an elastic member away from the connecting frame 4, the breaking rod 15 is conical; when the breaking rod 15 is slidingly installed on one side of the connecting frame 4, the breaking rod 15 can break and scrape the impurities on the surface of the extension plate 9, when encountering the impurities adhered too tightly, the breaking rod 15 can slide and shrink into the scraper 14, thereby buffering and protecting itself, at the same time, the breaking rod 15 and the scraper 14 can break and scrape the impurities adhered too tightly at the same time, thereby improving the breaking and scraping efficiency.

[0038] The inner wall of the groove 8 is fixedly installed with a hollow elastic block 17, the surface of the elastic block 17 is provided with a shrinkage hole, one end of the extension plate 9 close to the groove 8 is fixedly installed with a pressing plate 16, the extension plate 9 is sealingly and slidingly connected with the groove 8, one end of the connecting frame 4 is fixedly installed with an air outlet pipe 18, the other end of the air outlet pipe 18 is communicated with the groove 8; when the extension plate 9 is slidingly reset in the groove 8, the pressing plate 16 will extrude the elastic block 17, so that the gas in the elastic block 17 is sprayed out of the shrinkage hole and enters the air outlet pipe 18, the gas in the air outlet pipe 18 will assist blowing the impurities on the surface of the scraper 14, thereby quickly removing the impurities in the front of the scraper 14.

[0040] The one side of the baffle 6 close to the connecting frame 4 is fixedly installed with a magnetic block 28, the inside of the connecting frame 4 is provided with an inclined square groove 25, the inside of the square groove 25 is connected with a magnetic material pendulum ball 27 through a connecting rope, and the inside of the square groove 25 is rotatably connected with a plurality of arc-shaped impact pieces 26 through a torsion spring; when the connecting frame 4 moves downward, the magnetic block 28 no longer attracts the pendulum ball 27, at this time the pendulum ball 27 slides in the inclined square groove 25 to the direction of the placing groove 19, the pendulum ball 27 does not continuously impact the impact pieces 26 in the square groove 25, so that the impact pieces 26 make a sound, thereby playing a role in urging the wild animals in the connecting groove 5 to pass quickly, improving the passing time of the wild animals in the connecting groove 5, and at the same time the connecting frame 4 is reset, the magnetic pendulum ball 27 and the magnetic block 28 are attracted, the pendulum ball 27 is reset under the action of the connecting rope, thereby facilitating the next use of the pendulum ball 27.

[0041] The inside of the square groove 25 is provided with a through groove 29 communicated with the connecting groove 5, the inside of the through groove 29 is slidably connected with a slide rod 30, the top of the slide rod 30 is fixedly installed with an arc-shaped cover plate 31, and the arc-shaped cover plate 31 and the square groove 25 are fixedly connected with a spring; when the pendulum ball 27 slides in the square groove 25, the arc-shaped cover plate 31 in the square groove 25 is pressed, so that the cover plate 31 stretches out into the connecting groove 5 with the slide rod 30, the slide rod 30 drives the wild animals in the connecting groove 5 to move, and the arc-shaped cover plate 31 plays a role in transition and facilitating the movement of the pendulum ball 27, when the pendulum ball 27 slides to reset in the direction of the magnetic block 28, the arc-shaped cover plate 31 can also play a role in buffering and protecting the impact pieces 26, avoiding the pendulum ball 27 directly impacting the impact pieces 26, so that the impact pieces 26 are damaged.

[0042] The hydraulic rod 3 is fixedly connected with a corrugated pipe 32 near one end of the output end, and the other end of the corrugated pipe 32 is fixedly connected with the connecting frame 4; during work, the corrugated pipe 32 is installed on the hydraulic rod 3, the output rod of the hydraulic rod 3 is covered by the corrugated pipe 32, and the corrugated pipe 32 can also move along with the output rod of the hydraulic rod 3, so that the corrugated pipe 32 plays a role in protecting the output rod of the hydraulic rod 3, and effectively prevents impurities from adhering to the surface of the output rod; when the output rod is reset into the hydraulic rod 3, the impurities on the surface of the output rod will not scratch the hydraulic rod 3 and the output rod.

[0043] Example two: as shown in Figure 11 The bridge 1 is fixedly installed with a plurality of guide blocks 33 on one side close to the water level sensor 7, the guide blocks 33 are arc-shaped, and the water level sensor 7 is between the plurality of guide blocks 33; during work, the four sides of the water level sensor 7 are blocked by the guide blocks 33, thereby playing a role in protecting the water level sensor 7; when the accumulated water carries impurities through the culvert 2, the impurities floating on the water surface will not scratch the water level sensor 7, thereby playing a role in protecting the water level sensor 7.

[0044] Working principle: when it is plum rain season, rainwater will flow into the culvert 2, at this time, the water level in the culvert 2 will slowly rise, at this time, the water level sensor 7 will monitor the rising of the water level in the culvert 2, and will transmit the monitored information to the controller; when the water level reaches a certain value, the controller will start the hydraulic rod 3, so that the output end of the hydraulic rod 3 moves downward with the connecting frame 4; the controller can adjust the height of the connecting frame 4 according to the actual height of the water level, so that the connecting frame 4 is always located on the water surface, thereby facilitating the wild animals to pass through the culvert 2 through the connecting groove 5; when the water level decreases to a certain value, the controller will reset the connecting frame 4 to the top of the culvert 2 through the hydraulic rod 3; by setting the baffle 6, when the water level in the culvert 2 is high, at this time, the connecting frame 4 is located at the top of the culvert 2, and water may enter the connecting groove 5, causing the connecting groove 5 to be blocked; the two baffles 6 are arranged at the ports of the connecting groove 5, thereby effectively blocking the rainwater and impurities from entering the connecting groove 5; one side of the baffle 6 is arc-shaped, so as to better guide the rainwater, and facilitate the rainwater and impurities to pass through the culvert 2.

[0045] When the connecting frame 4 moves downward, the extension plate 9 in the groove 8 is no longer in contact with the guide plate 10 at the bottom of the baffle 6, at this time the spring in the groove 8 slides the extension plate 9 away from the groove 8, thereby extending the extension plate 9, at this time the wild animals can enter the connecting groove 5 through the extended extension plate 9, the extension plate 9 plays a role in reducing the height of entering the connecting groove 5, and the surface of the extension plate 9 is of a non-slip material, so it is more convenient for wild animals to enter, when the connecting frame 4 is reset, the arc-shaped extension plate 9 is in contact with the arc-shaped guide plate 10, the extension plate 9 slides into the groove 8 under the extrusion of the guide plate 10, thereby allowing the baffle 6 to be blocked in front of the extension plate 9, playing a role in protecting the connecting frame 4 and the connecting groove 5. When the extension plate 9 slides back into the groove 8, the scraper 14 will be in contact with the surface of the extension plate 9, since the extension plate 9 is arc-shaped, the scraper 14 can be matched with the sliding plate 12 to slide up and down to adapt to the extension plate 9, so that the bottom of the scraper 14 is always in contact with the surface of the extension plate 9, and the scraper 14 is arc-shaped, so that when the impurities accumulated at the front end of the scraper 14 become more and more, the arc-shaped scraper 14 can guide the impurities to roll away from the connecting frame 4, thereby removing the impurities, effectively avoiding the accumulation of impurities, and the rectangular plate 13 can slide up and down with the sliding plate 12, thereby effectively preventing impurities from entering the storage slot 11 and affecting the normal sliding of the sliding plate 12.

When the extension plate 9 slides back into the groove 8, it will drive the pressing plate 16 to extrude the elastic block 17, so that the gas in the elastic block 17 is discharged through the shrinkage hole and enters the air outlet pipe 18. The gas at the outlet of the air outlet pipe 18 blows the impurities on the surface of the scraper 14, thereby quickly removing the impurities at the front end of the scraper 14.

[0047] When the wild animals enter the connecting groove 5, the servo motor 20 at the end of the placement slot 19 is started, and the servo motor 20 drives the fan blade 21 to start rotating. The wind generated by the fan blade 21 blows towards the food 22, and the smell of the food 22 is discharged through the air outlet hole 24, thereby attracting the wild animals at the front end of the connecting groove 5, so that the wild animals can quickly reach the end of the connecting groove 5, thereby speeding up the efficiency of the wild animals passing through the connecting groove 5 and reducing their stay in the connecting groove 5.

[0048] When the connecting frame 4 moves downward, the magnetic block 28 no longer attracts the pendulum ball 27, at this time, the pendulum ball 27 slides in the inclined square groove 25 to the direction of the placing groove 19, the pendulum ball 27 does not break the impact piece 26 in the square groove 25, and the impact piece 26 makes a sound, thereby playing a role of urging the wild animals in the connecting groove 5 to pass quickly, improving the passing time of the wild animals in the connecting groove 5, and meanwhile, the connecting frame 4 resets, the pendulum ball 27 and the magnetic block 28 are attracted to each other, the pendulum ball 27 resets under the action of the connecting rope, thereby facilitating the next use of the pendulum ball 27. When the pendulum ball 27 slides in the square groove 25, the pendulum ball 27 can press the arc-shaped cover plate 31 in the square groove 25, so that the cover plate 31 stretches out into the connecting groove 5 with the slide rod 30, the slide rod 30 drives the wild animals in the connecting groove 5 to move, and the arc-shaped cover plate 31 plays a role of transition and facilitating the movement of the pendulum ball 27, when the pendulum ball 27 slides to reset in the direction of the magnetic block 28, the arc-shaped cover plate 31 can also play a role of buffering and protecting the impact piece 26, avoiding the direct impact of the pendulum ball 27 on the impact piece 26, and causing the impact piece 26 to be damaged. By installing the bellows 32 on the hydraulic rod 3, the bellows 32 covers the output rod of the hydraulic rod 3, and the bellows 32 can also move with the output rod of the hydraulic rod 3, so that the bellows 32 plays a role of protecting the output rod of the hydraulic rod 3, effectively preventing impurities from adhering to the surface of the output rod, and when the output rod resets into the hydraulic rod 3, the impurities on the surface of the output rod scratch the hydraulic rod 3 and the output rod.

1. A bridge-culvert structure facilitating the passage of wild animals, comprising a bridge (1), wherein the bottom of the bridge (1) is provided with a culvert (2); characterized in that: Several hydraulic rods (3) are fixedly installed on the top of the inner wall of the culvert (2). A connecting frame (4) is fixedly installed on the bottom of the hydraulic rod (3). A connecting groove (5) is opened on one side of the connecting frame (4). A water level sensor (7) is fixedly installed on the side wall of the culvert (2). A controller is fixedly installed on the top of the culvert (2). Two symmetrically arranged baffles (6) are fixedly installed on the inner wall of the culvert (2). The side of the baffle (6) away from the connecting frame (4) is arc-shaped. The water level sensor (7) will detect the rise in water level in culvert (2) and transmit the detected information to the controller. The controller will then activate the hydraulic rod (3) so that the output end of the hydraulic rod (3) moves the connecting frame (4) downward. The controller can adjust the height of the connecting frame (4) according to the actual height of the water level so that the connecting frame (4) is always on the water surface. When the water level drops to a certain value, the controller will then reset the connecting frame (4) to the top of culvert (2) through the hydraulic rod (3). The connecting frame (4) is located at the top of culvert (2) and is blocked at the port of the connecting groove (5) by two baffles (6). The connecting frame (4) has a placement slot (19) inside, a servo motor (20) is fixedly installed inside the placement slot (19), a fan blade (21) is fixedly connected to the output end of the servo motor (20), a limit plate (23) is fixedly installed inside the placement slot (19), food (22) is placed inside the placement slot (19), and an air vent (24) is opened inside the connecting frame (4). The two ends of the air vent (24) are connected to the placement slot (19) and the connecting slot (5). A magnetic block (28) is fixedly installed on the side of the baffle (6) near the connecting frame (4). An inclined square groove (25) is opened inside the connecting frame (4).
