Description

Technical Field

[0001] This utility model relates to the field of golden apple snail control technology, specifically to a device for capturing golden apple snails and their eggs. Background Technology

[0002] The golden apple snail, also known as the golden apple snail, is a mollusc belonging to the family Aquilegidae and the genus Aquilegia. Due to its strong adaptability and rapid growth and reproduction, it quickly spread after being abandoned, becoming a pest and causing serious harm to agricultural production, ecosystems, and public health.

[0003] The peak breeding season for golden apple snails is from May to August each year. At night, female snails climb to the pond wall, wooden stakes, or stems and leaves of aquatic plants 15 to 40 cm above the water surface to lay their eggs. Each egg-laying session lasts 20 to 80 minutes. After an interval of 3 to 5 days, they lay eggs a second time. They can lay eggs 20 to 40 times a year, with a total of 30,000 to 50,000 eggs.

[0004] The main control measures for golden apple snails are as follows:

[0005] 1. Physical control: snails are filtered by nets, manual cleaning, water level control, habitat destruction, etc. Disadvantages: high manpower consumption and low efficiency;

[0006] 2. Chemical control: 5% Meta-2, 6% Metformin granules, 85% Metformin wettable powder, 50% Metformin wettable powder, 60% Saponin·Nicotinic acid aqueous solution, etc. Disadvantages: severe pollution, pollutants may remain in soil, water and crops for a long time, and there is potential toxicity to animals and humans; indiscriminately kills other aquatic animals;

[0007] 3. Biological control: releasing ducks to control snails and ecological farming. Disadvantage: generally cannot eliminate adult snails with hard shells, but has a good control effect on juvenile snails.

[0008] Therefore, there is currently a lack of a solution for removing golden apple snails that is both effective, environmentally friendly, and labor-saving. Utility Model Content

[0038] Detailed Implementation

[0039] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0040] This utility model provides a device for capturing golden apple snails and their eggs, such as... Figures 1-6As shown, it includes an anti-snail spike pad 21, a trapping flower box 22, and a sleeve stake 23; the anti-snail spike pad 21, the trapping flower box 22, and the sleeve stake 23 are used together to ensure the best effect of capturing golden apple snails. In a preferred embodiment, the trapping flower box is rectangular in shape and has a height of 60~80cm.

[0041] The trapping flower box 22 is installed on the sleeve pile 23 and is in contact with the revetment; the trapping flower box 22 can float up and down with the change of the external water level; specifically, the trapping flower box is fixed close to the vertical revetment by the sleeve pile, the trapping flower box floats on the water surface, close to the water surface, and can float up and down with the change of the water level by the sleeve pile.

[0042] The revetment is also equipped with anti-snail spike pads 21. The surface of the anti-snail spike pads 21 is evenly distributed with fine spikes, which can effectively prevent golden apple snails from climbing up the revetment to lay eggs. A trapping channel 5 is provided on the revetment, which is connected to a trapping flower box 22. The trapping channel 5 does not contain anti-snail spike pads 21; however, the trapping channel 5 allows golden apple snails to climb into the trapping flower box, meaning that the trapping channel 5 facilitates upward climbing of the snails, and the trapping channel 5 leads directly to the trapping flower box. In a preferred embodiment, the anti-snail spike pads 21 are distributed on the left and right sides of the trapping flower box, with the trapping channel 5 only located directly below the trapping flower box 22. The width of the trapping channel 5 is 15-20 cm, facilitating upward climbing by the golden apple snails.

[0043] The trapping flower box is equipped with one-way doors 8. In a preferred embodiment, there are two one-way doors 8, symmetrically arranged, and they are mounted on the trapping flower box 22 via hinges 9. The golden apple snails can climb into the trapping flower box 22 through the trapping channel 5 via the one-way doors 8. The one-way doors 8 can only open inwards. After the golden apple snails enter the flower box, the one-way doors automatically close, preventing them from escaping after laying eggs, thus achieving the purpose of capturing the golden apple snails and their eggs. In another preferred embodiment, the trapping flower box has a partition in the middle, and the side walls of the partition are hinged with horizontally arranged stainless steel one-way doors. In this preferred embodiment, the one-way doors can only open into the inner cavity of the flower box, and the partition prevents them from opening outwards. Once the golden apple snails enter the inner cavity of the trapping flower box, the one-way doors automatically close, preventing them from climbing out.

[0044] The sleeve pile 23 includes a first steel pipe pile 3 and a second steel pipe pile 4; the first steel pipe pile 3 is fitted onto the second steel pipe pile 4 and can move vertically, the second steel pipe pile 4 is inserted into the bottom of the bank, and the first steel pipe pile 3 is securely connected to the trapping flower box 22. In a preferred embodiment, the first steel pipe pile 3 is a DN50mm steel pipe pile, and the second steel pipe pile 4 is a DN32mm steel pipe pile.

[0045] The anti-snail spike pad is made of polyvinyl chloride material. The anti-snail spike pad has two sides. The back side 1 of the anti-snail spike pad is a smooth surface that can be fixed on the revetment, and the bottom end is close to the mud surface. The front side 2 of the anti-snail spike pad has evenly distributed spike-like structures. It utilizes the principle that golden apple snails cannot wriggle on the spike tips with their abdominal feet to prevent them from climbing freely along the revetment.

[0046] The device for capturing golden apple snails and their eggs also includes a net bag 7. A hook is installed on the inner wall of the trapping flower box, and the net bag 7 is hung on the hook. Fresh plant leaves are placed inside the net bag 7 to lure the golden apple snails to climb upwards. The net bag can be replaced regularly by river maintenance workers.

[0047] The flower trapping box 22 has a baffle 6 about 30cm long fixed to its side wall, on which a 5cm thick wooden board is placed. After the wooden board is opened, workers can clean the golden apple snails and snail eggs inside the flower trapping box. Flower pots can be placed on top of the wooden board to beautify the river landscape. The front of the flower trapping box has an outward-opening door, which can be opened to clean the golden apple snails and snail eggs inside.

[0048] like Figure 3 As shown, the one-way door 8 includes a fixed surface 11, a rotating crossbar 12, a housing 24, and a door body 14. The fixed surface 11 has screw holes 10, which are used to fix the fixed surface 11 to the interior of the trapping flower box 22. The housing 24 is connected to the fixed surface 11, and the rotating crossbar 12 is installed in the housing 24. The housing 24 has an opening structure 13, and the end of the door body 14 passes through the opening structure 13 and is connected to the rotating crossbar 12 via a snap ring. Specifically, the opening angle of the one-way door is controlled by setting the width of the opening structure 13. In its natural state, the one-way door 14 is closed, close to the edge of 13. When a golden apple snail climbs into the trapping flower box and pushes open the one-way door, the rotating crossbar 12 rotates, the one-way door opens inward, and after the golden apple snail enters the trapping flower box, the one-way door returns to its natural closed state. Due to the obstruction of the edge and the control of the rotation angle of the rotating crossbar 12, the one-way door cannot be opened outward, meaning that the golden apple snail cannot crawl out of the trapping flower box.

[0049] The device for capturing golden apple snails and their eggs also includes an escape prevention structure 15, such as... Figures 4-6As shown, the escape-prevention structure 15 includes a mounting surface 16, a flexible part 17, and spikes 19. The escape-prevention structure 15 can be integrally manufactured. The mounting surface 16 is adhered to the trapping flower box 22; the flexible part 17 has a structure that is thicker at the bottom and tapered at the top, with the pointed part of the flexible part 17 facing the same direction as the apple snail crawls into the trapping flower box 22; one side of the flexible part 17 is a smooth surface 18; the other side of the flexible part 17 is provided with spikes 19; the free end of the spikes 19 faces the same direction as the apple snail crawls into the trapping flower box 22. The working principle of the escape-prevention structure 15 is as follows: when the apple snail crawls into the flower box, the pointed part naturally droops, the smooth surface 18 faces upward, and the smooth surface contacts the apple snail's foot, which further facilitates the apple snail's inward crawling. When the golden apple snail crawls out of the flower box, the direction of its pointed part changes, and the spikes 19 face upward. The spikes prevent the golden apple snail from climbing outward, thus preventing the golden apple snail from escaping.

[0050] The usage process of this utility model is as follows:

[0051] S1. One or two months before the peak breeding season of golden apple snails, lower the river water level to 10-15cm below the normal water level, lay snail-proof mats along the river, restore the river water level to normal, and ensure that the bottom of the snail-proof mats is submerged below the normal water level line; specifically, the bottom of the snail-proof mats can be close to the riverbed mud surface to ensure that golden apple snails cannot climb up the bank, thus improving the success rate of the device.

[0052] S2. Based on the snail density surveyed in the previous year, install trapping flower boxes; usually, one can be installed every 200m. If the snail density is too high, it can be adjusted to one every 150m.

[0053] S3. The trapping flower box is about 20cm away from the normal water level of the river. Fresh plant leaves are arranged in advance in the trapping flower box, and seasonal flowers are arranged on the trapping flower box to beautify the river landscape.

[0054] S4. Golden apple snails need to leave the water to lay eggs. Due to the restriction of the snail-proof pads, they can hardly move on the tips of the spikes with their abdominal feet. They can only climb up through the reserved trapping channel 5 to enter the trapping flower box.

[0055] S5. River maintenance workers regularly clean and crush the golden apple snails and snail eggs inside the flower box cavity, replace the fresh plant leaves inside the flower box cavity, check the fixation of the anti-snail spike pads, and check whether the one-way door of the flower box can be opened normally.

[0056] This invention primarily uses physical methods to trap and capture egg-laying golden apple snails. It is simple to use and can also serve as a form of vertical greening, beautifying urban waterways. The invention is easy to install and employs a comprehensive physical approach to prevent golden apple snails from climbing and laying eggs while trapping adult snails and their eggs. It poses no risk of environmental pollution and, in addition, enhances the aesthetics of hard revetments.
