[0052] The inside of the circular box 301 is rotatably provided with a rotating wheel 306, and the inside of the drainage box 307 is slidingly provided with a piston block 308; the bottom end middle portion of the rotating wheel 306 is provided with a connecting rod 309, and the end portion of the connecting rod 309 is provided with a gear head 311; the gear groove 310 is matched with the gear head 311, and the length of the gear head 311 is greater than the circumference of the gear head 311; the gear head 311 is a half gear to facilitate the conversion and utilization of driving force; and the top end middle portion of the piston block 308 is provided with a gear groove 310 at the position corresponding to the gear head 311.

[0053] The working principle and use process of the application are as follows: when the alien aquatic organism invasion trapping device is actually used, the air guide cylinder 316 is first pulled out to separate the air guide cylinder 316 from the filter box 315, release the limitation of the circular box 301, rotate the circular box 301, take it off from the floating seat 100, open the bait groove 201, fill the bait groove 201 with appropriate amount of submerged plants such as Vallisneria densespicata, Hydrilla verticillata and Iridaea serra according to actual needs, or fill the bait groove 201 with corresponding amount of attractant to replace it equivalently, then collectively refer to the filler in the bait groove 201 as attractant medium, then close the bait groove 201, reset the circular box 301 and the air guide cylinder 316 in turn, and after stably installing the net bag frame 101 at the bottom of the floating seat 100, the floating seat 100 can be put into the corresponding area.

[0054] The apple snail prefers shade, and is less active during the day, but active in the early morning and on cloudy days, and often clusters in the shallow water area of fresh water, sufficient bait of streams, rivers, lakes and farmland, and the apple snail likes to lay eggs on the pool wall 15-40 cm away from the water surface at night, and the most favorite object for laying eggs is bamboo pole piece, the pole piece 206 can be used to insert and fix the floating seat 100, and the relative water level of the floating seat 100 can be accurately limited according to the water depth, so that the shelf plate 212 is higher than the water surface 15-40 cm, the dark environment preferred by the apple snail can be artificially created, the attraction to the apple snail can be strengthened from the egg laying demand, and the food attraction can form a three-way linkage attraction.

[0055] After the floating seat 100 is deployed, the normal trapping of golden apple snails can be carried out. During the operation of the device, the presence of the wind gathering ball 303 can guide and converge the external airflow. After the airflow enters the wind gathering ball 303, it enters the bottom box 302 through the air guide port 304 and enters the round box 301 through the air duct 305, forcing the rotating wheel 306 to rotate. Driven by the connecting rod 309, the gear head 311 will rotate synchronously, and with the limiting effect of the gear groove 310, the piston block 308 is forced to move.

[0056] Here, under the linkage action of the connecting rod 309, a lever structure is formed between the rotating wheel 306 and the gear head 311. After amplifying the external airflow pressure, the piston block 308 is driven to move back, actively pulling and conveying the external airflow, forcing the external airflow to pass through the air guide cylinder 316, be filtered by the filter box 315, enter the drainage box 307 through the tee pipe 312, and be pressed into the round box 301 through the air outlet pipe 313. The amplified pressure is then applied to the rotating wheel 306 again, forming a cyclic amplification of the driving force.

[0057] The pressurized air then converges with the airflow gathered by the wind gathering ball 303 at the air delivery pipe 221 and is pressed into the drive box 215, forcing the wheel 216 to rotate via the shaft 217 and the gear head 218. Under the restriction of the tooth groove 214, the ring 213 is forced to drive the limit frame 219 and the scraper 220 to deflect synchronously, thereby achieving irregular scraping of the inner wall of the floating seat 100, the air diffusion seat 204 and the frame 212. The air then enters the annular channel 202 through the air receiving pipe 222 and enters the bait tank 201 through the filter tank 203. The scent of the attractant medium is flushed into the air diffusion seat 204 through the air guide valve 205 and evenly diffused to the outside in the water under the guidance of the air diffusion seat 204.

[0058] The effective coverage area of ​​the attractant medium is thereby expanded, and the snail's instinct to explore the source of food odor, as well as its tendency to move towards shade and avoid sunlight and its necessity to lay eggs, is utilized to force the snail to climb toward the top along the climbing rod 206, pass through the inner supporting spring piece 209, enter the interior of the floating seat 100, and naturally fall onto the hollow limiting seat 207 or continue to climb onto the shelf 212;

[0059] Under the sweeping action of the limiting frame 219 and the scraper 220, all the golden apple snails that have entered the floating seat 100 are swept onto the frame 212 and above the outer clamping spring piece 211. The golden apple snails that have fallen onto the frame 212 will roll along the top slope of the frame 212 onto the outer clamping spring piece 211. The outer clamping spring piece 211 will be deformed accordingly under the pressure of the gravity of the golden apple snails themselves. Finally, all the golden apple snails will fall into the net bag frame 101 for centralized collection.

[0060] After losing the oppression of the apple snail, the outer clamping spring 211 is automatically reset, which can prevent the apple snail from climbing out of the net bag frame 101, forming a first escape-proof structure. The existence of the inner to spring 209 and the multiple layers provided thereon can prevent the apple snail from climbing out of the floating seat 100, forming a second escape-proof structure, thereby avoiding the escape of the apple snail.

[0061] Finally, it should be noted that: the above only for the preferred examples of the present application, and not for limiting the present application, although the foregoing examples of the present application are described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement of the technical solutions recorded in the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
