Technical Field
[0001] This utility model relates to the field of water body restoration and golden apple snail control technology, specifically a golden apple snail trapping ecological soft enclosure. Background Technology
[0002] The golden apple snail (Pomacea canaliculata) is a globally invasive alien species, classified as one of the most dangerous invasive alien organisms in China. Belonging to the genus Pomacea canaliculata in the family Aquilegidae, it closely resembles a field snail in appearance and is characterized by its large size, wide diet, strong adaptability, rapid growth, and high reproductive rate. Due to its strong environmental adaptability and rapid reproduction rate, the golden apple snail has rapidly spread in rivers, lakes, and fields, posing a serious threat to ecosystems. Currently, the main methods for controlling the golden apple snail include manual capture, chemical treatment, and trapping. However, manual capture is time-consuming, labor-intensive, and inefficient, while chemical control may have adverse environmental impacts. Trapping, as the most convenient and ecological measure, is limited by specific spatial conditions.
[0003] In the practice of aquatic ecological management, the planting of submerged plants aims to improve water quality and restore the underwater ecosystem. However, this process inadvertently provides a carrier for golden apple snails, allowing them to be introduced into the management area and further complicating the handling of golden apple snail problems in aquatic ecological management. Ecological soft barriers, as a commonly used water isolation method in aquatic ecological management, have unexpectedly become an ideal spawning ground for golden apple snails due to their floating structures.
[0004] To address the aforementioned problem of golden apple snails, we propose a solution for ecological restoration of rivers and other waterways: designing and applying an ecological soft enclosure with snail-trapping capabilities. This enclosure, through targeted design, aims to effectively control and reduce the snail population while continuing to fulfill its isolating function in ecological restoration.

[0019] To make the purpose, principle and structure of this utility model clearer, the following description is provided in conjunction with the accompanying drawings and specific embodiments.
[0020] See Figure 1 This utility model provides an ecological soft enclosure for trapping golden apple snails, which includes: an underwater ecological soft enclosure 3, a float, a trapping box 15, and a sleeve tube 1.
[0021] The main material of the underwater ecological soft enclosure 3 is knife-coated cloth. The upper part is connected to the floating body, and the bottom is counterweighted by a deformable long chain 4. To ensure that it is not deformed by wind and waves, at least two equally spaced vertical steel pipe piles 2 are used to fix the ecological soft enclosure 3.
[0022] The main structure of the float is an EVA foamed floating plate, which is lightweight and hydrophobic. Specifically, it includes a first float 10.1 on the left, a second float 10.2 on the right, and a base 10 located between the first float 10.1 and the second float 10.2. The first float 10.1 and the second float 10.2 are connected to two adjacent sleeves 1, respectively. The sides of the first float 10.1 and the second float 10.2 near the sleeves 1 are edged with stainless steel 6, which is welded to the sleeves 1. Because the first float 10.1, the second float 10.2, and the base 10 are all made of EVA foam and are an integrated structure, buoyancy is generated between the float and the water, allowing the float to always float on the water surface. The sleeves 1 allow the float to slide up and down within the upper limit of the steel pipe column 2, and the float and sleeves 1 rise or fall with changes in water level.
[0023] A trapping box 15 is provided on the top of the base 10. A slope 13 with a slope ratio of 1:1.5 is provided on the front side of the base 10 where it contacts the water surface, providing a crawling trapping channel for the golden apple snails to reach the trapping box 15. The surfaces of the first float 10.1 and the second float 10.2 are decorated with artificial turf 9 to reduce the risk of golden apple snails attaching and to promote the entry of golden apple snails into the box through the trapping channel.
[0024] The bottom of the float is equipped with a crossbar, and the soft enclosure 3 is fixed to the crossbar at the bottom of the float by stainless steel fasteners.
[0025] The trapping box 15 has a frame structure. The left and right sides of the frame structure are enclosed by the inner surfaces of the first float 10.1 and the second float 10.2, respectively, and the bottom of the frame structure is enclosed by the top surface of the base 10. The trapping box 15 is equipped with inwardly opening one-way curtains 11 on both the front and rear sides. The top of the trapping box 15 has a removable mesh plate 8 for easy opening to release bait and collect captured golden apple snails. Both the curtains 11 and the mesh plate 8 have mesh openings to ensure the bait's scent diffuses outwards. The entire trapping box 15 is embedded in the float composed of the first float 10.1, the second float 10.2, and the base 10. The scent emitted by the bait attracts golden apple snails into the trapping box 15 through the trapping channel. The curtain 11 is movably connected to the frame structure of the trapping box 15 via a pivot 12. The top of the curtain 11 has a horizontal through hole, which is fitted onto the pivot 12. Both ends of the pivot 12 rotate and abut against the top of the inner side of the trapping box 15. The top of the cavity of the trapping box 15 has a limiting block 14 in front of the pivot 12. The limiting block 14 limits and blocks the curtain 11, so that the rotation angle of the curtain 11 on the pivot 12 is 90 degrees inward, realizing the one-way opening of the curtain 11. When the golden apple snail enters the trapping box 15, it will push up the curtain 11, causing the curtain 11 to rotate inward with the pivot 12 as the rotation center. When the golden apple snail is completely inside the trapping box 15, the curtain 11 loses the lifting force of the golden apple snail and falls back to the initial closed state under the action of gravity. Furthermore, a spring hinge can be installed at the pivot 12, allowing the curtain 11 to automatically close after the golden apple snail enters under the action of the pivot 12 with the spring hinge. The trapping box 15, through the one-way baffle curtain 11, ensures that the golden apple snail can only enter the inner cavity of the trapping box 15 from the outside of the channel, and once inside, it cannot escape, thus effectively achieving the purpose of trapping.
[0026] It also includes a steel pipe column 2 and a sleeve pipe 1 sleeved on the steel pipe column 2. The lower part of the steel pipe column 2 is inserted into the soil. The ratio of the lower part of the steel pipe column 2 to the upper part of the soil is 1:2. The part of the steel pipe column 2 that is exposed above the water surface is adjusted according to the water level. A limiting crossbar 7 is set at the top of the steel pipe column 2 above the water to ensure that the sleeve pipe 1 will not detach from the top of the steel pipe column 2 as the water level rises.
[0027] This utility model also includes the following steps and design details.
[0028] The underwater ecological soft enclosure 3 is mainly made of knife-coated fabric 3 with a thickness of ≥0.8mm. Its upper part is connected to the float via buckles, ensuring that the soft enclosure 3 can float up and down with water level changes under the buoyancy of the float. A deformable long chain 4 with a diameter of ≥10mm is connected to the bottom as a counterweight, ensuring that the soft enclosure 3 remains vertical underwater under the weight of the chain 4. A steel pipe column 2 and a sleeve pipe 1 are installed every 2 meters for fixation. The soft enclosure 3 can also be moved between the steel pipe column 2 and the sleeve pipe 1 using buckles.
[0029] The main material of the float is EVA foamed floating board with a density of 0.04 g / cm³ and a total thickness of 300 mm. The sides of the first float 10.1 and the second float 10.2 are edged with 304 stainless steel 6, which is welded to the sleeve tube 1 to ensure a firm connection between the float and the sleeve tube 1. The stainless steel edging 6 is 1 mm thick and 30 mm wide. The float and the soft enclosure 3 are fixed with stainless steel fasteners to ensure a tight connection between the soft enclosure 3 and the float. A trap box 15 is embedded in the float. The part of the base 10 in the float that contacts the water surface is designed as a slope 13 with a slope ratio of 1:1.5 to facilitate the golden apple snails crawling into the trap box 15. Except for the slope 13 of the trap box 15, the surface of the float is decorated with artificial turf 9 for the first float 10.1 and the second float 10.2.
[0030] The trapping box 15 measures 500*350*160mm. Both the front and rear sides are equipped with PE material curtains 11 that open in one direction. The curtains 11 are 0.5mm thick and the mesh size of the curtains 11 is ≤5mm. The top of the trapping box 15 is equipped with a mesh plate 8 with a mesh size ≤10mm. The mesh plate 8 can be opened to facilitate the placement of bait and the collection of captured golden apple snails.
[0031] Sleeve 1 has a diameter of 60mm and a length of 500mm. Steel pipe column 2 has a diameter of 48mm, and its length is adjusted according to the water depth. The ratio of the submerged portion to the above-mud portion of steel pipe column 2 is 1:2. The portion of steel pipe column 2 above the water surface is adjusted according to water level changes. A limiting crossbar 7 is installed at the top of the above-water steel pipe column 2 to ensure that sleeve 1 does not detach from steel pipe column 2. Piling can be performed manually or using an underwater piling machine.
