[0002] Landscape water bodies are important ecosystems in cities or parks, not only beautifying the environment, regulating the climate, and improving air quality, but also carrying rich aquatic organisms and ecological functions. However, with the invasion of the golden apple snail, due to its strong adaptability and reproductive capacity, it has spread widely to all parts of the world, especially to landscape water bodies and rice fields in China, becoming a serious invasive alien species. Therefore, in order to effectively reduce the harm of golden apple snails to water bodies, chemical agents, manual harvesting, and trapping devices are usually used to control the golden apple snail population.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figures 1-4This utility model provides an embodiment of a snail trapping device suitable for landscape water bodies, comprising a trapping cage 1 and a black floating plate 11. A bait box 35 is installed in the middle of the trapping cage 1, a collection box 10 is installed at the bottom of the trapping cage 1, a retraction channel 6 is fixedly connected to the middle of the trapping cage 1, a toothed ring 2 is rotatably connected to the outer periphery of the trapping cage 1, a shell 4 is fixedly connected to the top of the trapping cage 1, a rotating rod 24 is rotatably connected to the middle of the shell 4, a winding roller 25 is fixedly connected to the outer periphery of the rotating rod 24, a rope 5 is sleeved on the outer periphery of the winding roller 25, and a connecting component is installed at the other end of the rope 5, connecting the component to the black floating plate 11. A gear 26 is fixedly connected to the outer periphery of the rotating rod 24, meshing with the toothed ring 2. A rocker arm is rotatably connected to the top of the trapping cage 1. The rocker arm 29 has a gear 30 fixedly connected to its outer periphery, which meshes with the gear ring 2. A ratchet 31 is fixedly connected to the outer periphery of the rocker arm 29. A locking assembly is installed on the outer periphery of the rocker arm 29. The connecting assembly includes a hook 28, which is fixedly connected to the end of the rope 5 away from the winding roller 25. A hanging ring 27 is fixedly connected to the bottom of the black floating plate 11, and the hook 28 is engaged in the middle of the hanging ring 27. The locking assembly includes a vertical rod 33, which is fixedly connected to the top of the trap cage 1. A pawl 34 is rotatably connected to the outer periphery of the vertical rod 33, and the pawl 34 contacts the ratchet 31. A spring plate 32 is fixedly connected to the top of the trap cage 1, and the spring plate 32 contacts the pawl 34. The collection box 10 is conical in shape, and the diameter of the black floating plate 11 is larger than the diameter of the trap cage 1.First, the conical collection box 10 is inserted into the silt at the bottom of the water, so that the trap 1 can remain at the bottom of the water. This ensures that the ground of the constriction channel 6 is at the same level as the silt at the bottom of the water, allowing the attracted golden apple snails to enter the device through the constriction channel 6 under the action of the bait box 35 containing plant bait. At the same time, turning the rocker arm 29 drives the gear 2 30 to rotate, which in turn drives the gear ring 2 to rotate. The gear ring 2 then drives the gear 26 to rotate, which in turn drives the winding roller 25 through the rotating rod 24 to release the rope 5. The rope 5 is pulled straight out from the middle of the outer shell 4 by the upward pull of the black floating plate 11. At the same time, the spring plate 32 and the pawl 34 can resist the ratchet 31, so that the rocker arm 29 can be locked by the ratchet 31. To prevent the black floating plate 11 from being pulled by the current and causing the rope 5 to continue to be released, the ratchet 34 is pressed to separate from the ratchet 31, and the rocker arm 29 is turned in the opposite direction to reel in the rope 5. This allows for adjustment of the rope 5 length according to the water depth, thereby tightening the black floating plate 11 and ensuring that the black floating plate 11 is always at the top of the device. This allows the black floating plate 11 to be positioned on the water surface at the top of the device, thus blocking sunlight. This helps to attract and gather apple snails near the device by taking advantage of their tendency to avoid strong light, making it easier to trap them. At the same time, the black floating plate 11 makes the device's location easy to identify, so that people can quickly identify the location and remove the device from the water after a long period of collection. The black floating plate 11 can also be quickly disassembled and replaced as needed using the hanging ring 27 and the hook 28.

[0041] Reference Figure 1 and Figure 5A round rod 18 is rotatably connected to the top of the trap cage 1. A rotating cover 3 is fixedly connected to the outer periphery of the round rod 18. A torsion spring 19 is installed between the rotating cover 3 and the trap cage 1. A retaining ring 13 is fixedly connected to the outer periphery of the bait box 35. The bait box 35 is slidably connected to the middle of the trap cage 1. The retaining ring 13 is slidably connected to the middle of the trap cage 1. A yellow-green fluorescent stick 17 is slidably connected to the middle of the retaining ring 13. A stop block 16 is fixedly connected to the top of the yellow-green fluorescent stick 17. The stop block 16 is slidably connected to the middle of the retaining ring 13. A slot 14 is opened at the top of the trap cage 1. The retaining ring 13 is slidably connected to the middle of the slot 14. A sliding groove 15 is opened in the middle of the retaining ring 13. The stop block 16 is slidably connected to the middle of the sliding groove 15. The yellow-green fluorescent stick 17 passes through the retaining ring 13 and the top wall of the trap cage 1 from top to bottom. By pushing the rotating cover 3 to rotate, the bait box 35 can be quickly removed from the middle of the trap cage 1. At the same time, when the bait box 35 is removed, the yellow-green fluorescent stick 17 will be pulled out from the middle of the trap cage 1, so that the bait and the yellow-green fluorescent stick 17 in the bait box 35 can be quickly replaced. At the same time, when the rotating cover 3 rotates, it will drive the torsion spring 19 to rotate. After the rotating cover 3 is released, the torsion spring 19 will reset the rotating cover 3, so that the rotating cover 3 can fix the bait box 35 and the yellow-green fluorescent stick 17 in the middle of the trap cage 1. At the same time, under the action of the retaining ring 13 and the retaining groove 14, as well as the stop block 16 and the sliding groove 15, the retaining ring 13 and the stop block 16 can be at the same level as the top surface of the trap cage 1, thereby ensuring that the rotating cover 3 can fix the bait box 35 and the yellow-green fluorescent stick 17, and the bait box 35 and the yellow-green fluorescent stick 17 will not fall into the trap cage 1.

[0042] Reference Figures 5-7 A connecting tube 12 is fixedly connected to the middle of the trap cage 1. The retractable channel 6 is connected to the connecting tube 12. An upper ring 7 is fixedly connected to the outer periphery of the trap cage 1. A lower ring 8 is fixedly connected to the outer periphery of the collection box 10. A sleeve 9 is fixedly connected to the top of the upper ring 7. A locking rod 21 is slidably connected to the middle of the sleeve 9. A pull block 23 is fixedly connected to one end of the locking rod 21. The other end of the locking rod 21 is slidably connected to the middle of the lower ring 8. A compression spring 22 is sleeved on the outer periphery of the locking rod 21. An insertion hole 20 is opened in the middle of the lower ring 8. The locking rod 21 is slidably connected to the middle of the insertion hole 20. The lured golden apple snails enter through the constriction channel 6 via the connecting tube 12. The connecting tube 12 is connected to the collection box 10, allowing the snails to be collected. After prolonged trapping, the device is removed, and the lever 21 is pulled out from the middle of the lower ring 8 and rotated, allowing the collection box 10 to quickly separate from the trapping cage 1 for easy removal and centralized processing of the golden apple snails. Simultaneously, pulling the lever 21 causes the pull block 23 to compress the spring 22. Aligning the lever 21 with the insertion hole 20 and releasing it allows the lever 21 to be quickly inserted into the lower ring 8, facilitating the rapid installation of the collection box 10 and the trapping cage 1.

[0043] Working principle: First, the collection box 10 is inserted into the silt at the bottom of the water, so that the contraction channel 6 is located at the bottom of the water. At the same time, the rocker arm 29 is turned to drive the gear 2 30 to rotate, which in turn drives the gear ring 2 to rotate. The gear ring 2 drives the gear 1 26 to rotate, which in turn drives the winding roller 25 to rotate through the rotating rod 24 to release the rope 5. The rope 5 is pulled out from the middle of the outer shell 4 by the upward pull of the black floating plate 11. At the same time, the ratchet 34 can lock the rocker arm 29 by the ratchet 31, preventing the black floating plate 11 from pulling the rope 5 under the action of the current and continuing to release it. This ensures that the black floating plate 11 is always at the top of the device, so that the black floating plate 11 is at the water surface at the top of the device to block the sunlight. This makes it easier to attract and gather the golden apple snails near the device by taking advantage of their tendency to avoid strong light, thus facilitating the trapping.

[0044] The bait placed in the bait box 35 and the faint yellow-green light emitted by the yellow-green glow stick 17 allow the device to improve the nighttime attraction efficiency by utilizing the light-odor synergy effect through the slight weakening of the yellow-green light by the plant bait and the golden apple snail. At the same time, the rotating cover 3 can prevent the plant bait and the yellow-green glow stick 17 from floating out of the trap cage 1 due to the buoyancy of the water.

[0045] Guided by the contraction channel 6 and the connecting cylinder 12, the golden apple snails enter the collection box 10. After a long period of trapping, the device is removed, and the lever 21 is pulled out from the middle of the lower ring 8 and rotated, so that the collection box 10 can be quickly separated from the trap cage 1, so that the golden apple snails can be quickly removed and centrally processed. At the same time, pulling the lever 21 will drive the pull block 23 to squeeze the compression spring 22. After aligning the lever 21 with the insertion hole 20, it is released, so that the lever 21 can be quickly inserted into the lower ring 8, so that the collection box 10 and the trap cage 1 can be quickly installed.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
