Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of trapping of alien invasive organisms, in particular to a mobile trapping device suitable for apple snails. BACKGROUND

[0002] Apple snails, commonly known as large bottle snails or apple snails, belong to the Gastropoda and Ampullariidae, and are originally from the Amazon River Basin in South America. They have become a major invasive species that threatens global biodiversity, agricultural production, and human health. Apple snails prefer to invade areas with dense water networks. Once they successfully colonize, they can quickly spread along rivers, ditches, and farmland with water flow. Floods and irrigation activities can significantly accelerate their spread. These invasive snails pose a serious threat to agricultural production, particularly to water-based economic crops such as rice, beans, potatoes, sweet potatoes, lotus roots, and water chestnuts. Their typical method of damage is to eat the leaves of host plants.

[0003] Existing apple snail trapping devices are mainly cage-type traps. The cage is placed in the water and remains stationary, making it vulnerable to water flow. The water flow can cause the trap to move, causing the cage, which was originally placed in an area with a high concentration of apple snails, to deviate from the optimal trapping position, reducing the trapping efficiency. Moreover, it is difficult to adjust the position of the trap according to the location of the apple snails, making it difficult to effectively trap the apple snails in a timely manner and miss the best trapping opportunity. This allows the apple snails more time to reproduce and spread, making it difficult to control their population from the source and thus protecting the growing environment of water-based crops. SUMMARY

[0004] The main purpose of the present application is to provide a mobile trapping device suitable for apple snails to overcome the problems in the prior art.

[0011] Further, the top of the support is fixedly installed with solar panels on both sides.

[0012] Through the technical scheme, the electric push rod in the fixing unit drives the inserting rod to be obliquely inserted into the mud layer at the bottom of the water along the limiting inclined hole, and the trapping box body can be firmly fixed at the target position by the friction force between the radially distributed inserting rods and the mud layer, so that the device can effectively resist the impact of water flow and wind disturbance and avoid displacement, inclination or overturning.

[0013] Further, each one-way assembly comprises a one-way valve, the number of the one-way valves is set to be multiple groups, the number of the one-way valves in each group is set to be multiple, the multiple one-way valves are arranged in a ring array, the inside of each group of one-way valves is provided with a through hole, the size of the through hole is matched with the size of the inserting rod, one side of each trapping channel is provided with an opening, and each one-way valve is hingedly connected with the inner wall of the corresponding opening.

[0014] Through the technical scheme, the multiple one-way valves arranged in a ring array in the one-way assembly can ensure that the apple snails can smoothly enter the box body along the inserting rod through the characteristics of being flexibly turned inward and the through hole structure matched with the inserting rod, and avoid the escape of the captured apple snails due to movement or shaking of the device.

[0015] Further, the top of the trapping box body is provided with at least one opening, and one side of each opening is hingedly connected with a cover plate.

[0016] Through the technical scheme, the number of the captured apple snails in the box can be directly observed through the opening, and it can be determined in time whether cleaning is needed, so as to avoid wasting manpower due to blind fishing, and the bait can be directly supplemented into the box through the opening after the cover plate is opened.

DETAILED DESCRIPTION

[0022] The technical solutions of the present application are further described below by the drawings and examples.

[0023] In combination Figures 1 to 8 , the embodiment provides a movable trapping device suitable for apple snails, which comprises a trapping box 1, a plurality of trapping channels 2 are formed on the outer side of the trapping box 1, the plurality of trapping channels 2 are all in communication with the trapping box 1, a moving assembly is arranged on the top of the trapping box 1, and a one-way assembly is arranged in the plurality of trapping channels 2. The moving assembly comprises a driving unit and a fixing unit, the fixing unit comprises a plurality of plug rods 7, the plurality of plug rods 7 are used for fixing the position of the trapping box 1, and the driving unit comprises a fan 16 and a floating plate 13, the floating plate 13 and the fan 16 are used for driving the trapping box 1 to move.

[0024] In the embodiment, the trapping box, the moving assembly and the one-way assembly all adopt green imitation crops. By adopting the scheme, the apple snails are more likely to be induced to climb onto the trapping box.

[0025] Referring to Figures 1-8 , the trapping box 1 is hollow, the floating plate 13 is fixedly connected to the bottom of the trapping box 1, the number of the fan 16 is set to be multiple, the plurality of fans 16 are uniformly distributed on the top of the trapping box 1, the bracket 4 is fixedly connected to the top of the trapping box 1, the electric push rod 5 is fixedly installed on the top of the bracket 4, the output end of the electric push rod 5 penetrates through one side of the bracket 4 and is fixedly connected with the disc 6, a plurality of sliding grooves 10 are formed in the bottom of the disc 6, the moving seat 11 is slidingly connected in each sliding groove 10, each moving seat 11 is rotatably connected with the top end of the corresponding plug rod 7, a plurality of limiting inclined holes 8 are formed in the top of the trapping box 1, the plurality of trapping channels 2, the plug rods 7 and the limiting inclined holes 8 are correspondingly arranged, the bottom end of each plug rod 7 extends to the outer side of the trapping box 1 after penetrating through the corresponding limiting inclined hole 8 and the trapping channel 2 in sequence, and the solar panels 12 are fixedly installed on the top of the bracket 4.

[0026] The driving unit can drive the trapping box 1 to move when the trapping box 1 floats in the lotus root field. The specific driving mode is that the trapping box 1 is first placed on the water surface, and at this time the trapping box 1 is in a floating state. When the apple snail gathering area is found, since the solar panels 12 are fixedly installed on the top of the two sides of the support 4, (the model of the solar panels 12 is SK-TFS15, which is prior art, and the specific working principle is not described here, and the power is 15W, the size is large, and it is suitable for the environment with relatively less light, and the charging efficiency is high), since the solar panels 12 are composed of a plurality of solar cells, when the sunlight shines on the solar panels 12, the electricity will be stored, and a part of the generated electricity directly powers the electric push rod 5 and the plurality of fans 16 to drive them to work, and the other part is stored in the built-in battery to provide stable power support for the device in the case of insufficient light such as cloudy days and nights.

[0027] Among them, the fan 16 is prior art, which is not described here, and the inside is provided with a driving motor for driving.

[0028] After the plurality of fans 16 obtain power (the power comes from the real-time power generation of the solar panels 12 or the stored power of the battery, and the power supply source is automatically switched by the circuit system according to the light condition), the fans 16 at different positions can be selectively driven according to the target moving direction. According to Newton's third law, the air being pushed will generate a counteracting force in the opposite direction of the fan 16. The counteracting force of a single or multiple fans 16 is transmitted to the trapping box 1 through the support 4. At this time, the bottom floating plate 13 of the trapping box 1 makes it float on the water surface. Under the driving of the directional counteracting force, the device moves smoothly in the preset direction. In the moving process, the solar panels 12 continuously charge the battery to ensure that the fans 16 can still work stably when the light changes, and stop running until reaching the apple snail gathering area.

[0029] By selectively driving fans 16 at different positions through the driving unit, the device can flexibly adjust the moving direction and accurately sail to the apple snail gathering area, changing the problem that the traditional trapping cage is stationary and easy to deviate from the target. It makes the capture more targeted, and can dynamically adjust the capture position according to the activity track of the apple snail, effectively improves the capture efficiency per unit time, and better protects the growth environment of aquatic crops from the source to curb the reproduction and spread of the apple snail.

[0030] The fixed unit can fix the trap box 1 at its position when the apple snail gathering place is found. The specific fixing method is that when the device reaches the apple snail gathering area by the driving unit and stops moving, the electric push rod 5 at the top of the support 4 is started under the power of the solar panel 12 or the battery, the output end of the electric push rod 5 extends outward, pushes the disc 6 fixedly connected thereto to move downward, the moving seat 11 in the sliding groove 10 at the bottom of the disc 6 descends synchronously with the disc 6, since each moving seat 11 is rotatably connected with the top end of the corresponding insertion rod 7, and the insertion rod 7 penetrates the limiting inclined hole 8 at the top of the trap box 1, under the inclined guiding action of the limiting inclined hole 8, the insertion rod 7 moves downward along the inclined direction, the bottom end of the insertion rod 7 penetrates the limiting inclined hole 8 and the trap channel 2 in turn, and gradually extends to the outside of the trap box 1 and is inserted into the bottom mud layer. As the electric push rod 5 continues to extend, the depth of the insertion rod 7 inserted into the mud layer increases continuously. According to the water depth, the output end of the electric push rod 5 can be extended to a specified length, until the multiple insertion rods 7 are radially and stably rooted in the bottom mud, and the trap box 1 is firmly fixed at the target position through the friction with the mud layer and the restraining action of the limiting inclined hole 8, so as to avoid displacement, inclination or even overturning of the device under the action of water flow or wind force, ensure that the trap channel 2 always faces the apple snail activity area, prevent the apple snails that have entered the box from escaping from the one-way assembly due to shaking of the device, and provide stable structural support for efficient trapping.

[0031] The electric push rod 5 in the fixed unit drives the insertion rod 7 to be inserted into the bottom mud layer along the limiting inclined hole 8, and the trap box 1 can be firmly fixed at the target position by the friction between the radially distributed insertion rods 7 and the mud layer, which effectively resists water flow impact and wind disturbance, avoids displacement, inclination or overturning of the device, solves the problem that the traditional trap cage easily deviates from the trapping area due to environmental shaking, and at the same time, accurate fixing ensures that the trap channel 2 always faces the apple snail activity area, reduces the decline of trapping efficiency caused by position deviation, prevents the apple snails that have entered the box from escaping from the one-way assembly due to shaking of the device, and in addition, the electric push rod 5 can flexibly adjust the insertion depth of the insertion rod 7 according to the water depth, adapt to different water environments, and provide reliable structural support for stable and efficient trapping of apple snails by the device, further guaranteeing the growth environment of aquatic crops and the ecological balance of water area.

[0032] Referring to Figures 4-6 Each one-way assembly includes a one-way petal 14, the number of one-way petals 14 is set to multiple groups, the number of one-way petals 14 in each group is set to multiple, the multiple one-way petals 14 are arranged in a ring array, a through hole 15 is formed in the inside of each group of one-way petals 14, the size of the through hole 15 is adapted to the size of the insertion rod 7, an opening 9 is formed on one side of each trap channel 2, and each one-way petal 14 is hingedly connected with the inner wall of the corresponding opening 9.

[0033] The one-way valve 14 is made of flexible material of low-density polyethylene, which can easily turn inward under the thrust of the apple snail and tightly fit the plug rod 7 to form a seal, ensuring smooth entry.

[0034] When the apple snail is attracted by the bait in the trap box and crawls along the plug rod 7 inside the trap channel 2, it will contact the multiple sets of one-way valves 14 arranged in a ring array inside the channel. Since each set of one-way valves 14 is hinged to the inner wall of the opening 9 on one side of the trap channel 2, and the one-way valves 14 can flexibly rotate inward, the thrust generated by the apple snail crawling along the plug rod 7 will push the one-way valves 14 open, causing them to turn inward into the box. Meanwhile, the through hole 15 inside the one-way valve 14 is sized to fit the plug rod 7, and the plug rod 7 passing through the through hole 15 will not hinder the rotation of the one-way valve 14, forming a channel for the apple snail to pass through smoothly, ensuring that it can crawl into the trap box 1 along the plug rod 7. When the apple snail tries to crawl out of the box in the opposite direction, its body will move along the plug rod 7 to the outside of the channel and push the one-way valves 14, but the hinged structure of the one-way valves 14 and the opening 9 only allows them to turn inward, and turning outward will be blocked by the inner wall of the opening 9, making it impossible to form a passage. At the same time, the multiple sets of one-way valves 14 arranged in a ring array block the exit on the inside of the channel from different angles, and each set of multiple one-way valves 14 overlaps each other, making it difficult for the apple snail's shell and foot to push open all the one-way valves 14 to find a gap, ultimately trapping it firmly inside the box.

[0035] The multiple sets of one-way valves 14 arranged in a ring array in the one-way assembly not only ensure that the apple snail can enter the box smoothly along the plug rod 7 through the flexible inward turning feature and the through hole 15 structure that fits the plug rod 7, but also physically block the escape path in the opposite direction through the one-way restriction of the hinged structure and the overlapping blocking effect, preventing the captured apple snail from escaping due to movement or device shaking. This not only improves the success rate of a single trap and reduces bait waste, but also eliminates the need for additional power to maintain the anti-escape state. In combination with the trap channel 2, it forms a targeted capture path, effectively improving the device's continuous interception efficiency of apple snails, reducing the harm to aquatic crops and the ecological environment caused by their reproduction and spread.

[0036] Referring to Figures 1-3 The top of the trap box 1 is provided with at least one opening 3, and each opening 3 is hinged with a cover plate 17 on one side.

[0037] Through the setting of the through hole 3 and the cover plate 17, the operator does not need to salvage the device as a whole, only needs to turn over the hinged cover plate 17, can directly observe the captured amount of apple snails in the box through the through hole 3, and timely judge whether it needs to be cleaned, avoids wasting manpower due to blind salvage, and directly supplements the bait in the box through the through hole 3 after opening the cover plate 17, without disassembling the device or interrupting the capture process, ensures that the bait continuously emits odor to attract apple snails, and maintains the high-efficiency capture state of the device.

[0038] Working principle: first, open the cover plate 17 to supplement the bait in the box, then place the entire trapping box 1 on the water surface, the device relies on the bottom floating plate 13 to float on the lotus root field water surface, the solar panel 12 at the top of the support 4 converts light energy into electrical energy, a part directly powers the electric push rod 5 and the fan 16 to work, and the other part is stored in the storage battery for standby, when the apple snail gathering area is found, the circuit system selectively drives the corresponding position of the fan 16 according to the moving direction, the fan 16 drives the device to move stably along the preset direction; After reaching the target area, the electric push rod 5 is extended, the moving seat 11 is lowered through the disc 6 sliding groove 10, the insertion rod 7 is inserted into the water bottom mud layer along the limiting inclined hole 8, the radially arranged insertion rod 7 is firmly fixed by the friction with the mud layer, avoiding displacement or shaking, at this time, the odor emitted by the bait in the box attracts apple snails, the apple snails climb along the insertion rod 7 penetrating the trapping channel 2, open the one-way flap 14 to enter the box; when the apple snails try to climb out in reverse, the one-way flap 14 cannot be turned outward due to the hinged structure, and the multiple groups of annular superimposed one-way flaps 14 form a blockage to prevent it from escaping, at this time, the operator can check the captured amount and supplement the bait through the top through hole 3 and the hinged cover plate 17 at any time, without interrupting the capture process, realizing directional movement capture, stable fixation and efficient interception of apple snails, and completing the complete work flow from starting power supply, directional movement, accurate fixation to continuous capture and convenient maintenance.

[0039] The above is only the preferred embodiment of the present application, and does not limit the technical scope of the present application in any way, so any slight modification, equivalent change and modification of the above embodiment according to the technical essence of the present application still belongs to the scope of the technical solution of the present application.
