Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of apple snail prevention and control, and particularly relates to a triggered light-induced continuous snail catching visual device. BACKGROUND

[0002] The apple snail, also known as the apple snail, belongs to the Gastropoda and Ampullariidae, and mainly inhabits in tropical and subtropical regions. As the first batch of invasive alien species, the apple snail has an advantage in competition with native species due to the lack of natural enemies and strong adaptability and high reproductive capacity in the invaded area, resulting in a large number of local species reduction or extinction. At the same time, the apple snail mainly feeds on aquatic plants such as rice seedlings, tender branches and leaves of wild rice, and destroys the aquatic ecosystem, reducing the biodiversity of the aquatic environment in the invaded area.

[0003] With the continuous expansion of the apple snail invasion range, and the tendency to invade north of the Yangtze River, it poses a serious threat to the biodiversity protection and aquatic ecological environment of China. Prevention and control of alien invasive species is an important part of biological safety management. At present, the physical control measures mainly remove the apple snail through artificial snail catching and egg picking. For the area where the apple snail breaks out, artificial removal is difficult to cope with the rapid growth of the apple snail population, and artificial snail catching and egg picking will increase the risk of transmission of parasites or viruses. Overall, the current physical control means still has the disadvantages of high labor cost and poor timeliness, while the apple snail has strong reproductive capacity and strong diffusion capacity, and the physical control measures need to be improved.

[0004] Although there are some apple snail trapping devices at present, there are still many defects, for example, a field irrigation water apple snail interception and trapping device disclosed in patent CN219479019U includes a fixed insertion rod, a trap and a closure cover; the fixed insertion rod is hollow inside and is provided with a collection net bag, the fixed insertion rod is connected with the trap at the top, the trap has a plurality of movable doors with the weight of the upper end being greater than that of the lower end; the apple snail climbs to the upper end of the movable door, when the weight of the apple snail plus the weight of the upper end of the movable door is greater than the weight of the lower end of the movable door, the movable door turns inward to make the apple snail fall into the collection net bag, and after the apple snail falls, the weight of the lower end is greater than that of the upper end again, and the movable door reversely rotates to realize resetting. The device has the following shortcomings:

[0005] (1) The trapping device ignores the motion principle of the apple snail, even if the one-way door of the space trap is triggered, it cannot guarantee that the apple snail attached to the space trap will fall into the collection net bag with the one-way door turning downward, and once the apple snail continues to attach to the space trap, the trapping device becomes a breeding ground for the apple snail to lay eggs.

[0006] (2) The one-way movable door of the space trap of the trapping device only determines the trigger threshold according to the principle of mechanical equilibrium, and the apple snails that can be trapped are limited by the mass factor.

[0007] The above two points are inherent shortcomings of the trap structure, and the above problems cannot be solved by relying on mechanical design alone.

[0008] (3) The application place of the device is limited, only suitable for static water areas such as farmland, and the height of the device cannot be adjusted. Once the water level is too low, the apple snails will lay eggs on the fixed insertion rod, and the device cannot capture the apple snails, but provides breeding conditions for the apple snails. When the water level is too high, the device will be flooded. SUMMARY

[0009] The purpose of the present application is to provide a trigger type light-induced continuous snail catching visual device, which can automatically capture apple snails and solve the above problems existing in the existing apple snail trapping device.

[0010] To achieve the above purpose, the specific technical solutions adopted by the present application are as follows:

[0011] A trigger type light-induced continuous snail catching visual device, comprising a space trap and a collection container; the space trap is a hollow cylindrical structure with an open bottom, and a plurality of door frames are arranged on the peripheral wall of the cylindrical structure, and an active door is installed in each door frame; the active door comprises door plates rotatably connected to the door frames on both sides and a door sleeve sleeved at the bottom end of the door plate, and the door sleeve slides down to cover the door plate when the door plate is pressed to turn inward, and the apple snails adhering to the door plate are knocked off during the sliding process; the collection container is arranged below the space trap and is used to receive the apple snails falling with the active door turning inward.

[0012] The device of the present application is provided with a space trap with a plurality of active doors, and the active door is designed as a structure combined with a turnable door plate and a slidable door sleeve, which ensures that the apple snails adhering to the door can fall into the collection container after the active door turns inward, avoiding the problem that the apple snails adhering to the door are difficult to fall and collect in the existing trapping device.

[0013] Further, the door plates are rotatably connected to the door frames through the door shafts arranged on both sides, and the door sleeves are provided with sliding grooves on both sides, and the door shafts are arranged through the sliding grooves. Through such a structure, the door sleeve slides with the door plate turning.

[0014] Further, a blocking plate is arranged at the bottom of the door frame to block the bottom of the active door turning inward, so as to avoid the active door turning too much to the outside of the door frame.

[0015] Further, the door panel is provided with a pressure sensor, which is triggered when the apple snail climbs on the door panel to make the movable door turn inward; the bottom of the door panel is provided with a switch, and the door cover slides down to cover the door panel and touch the switch to make the movable door turn outward to restore the initial state. The device triggers the movable door to turn through the pressure sensing, and realizes the reset of the movable door by touching the switch through the sliding of the door cover, which replaces the operation mode of the existing trapping device through the weight difference of the movable door area, and the operation mode of the movable door of the device is not affected by the mass of the apple snail and is not limited by the trigger threshold, and the response is faster.

[0016] Further, the bottom of the space trap is connected with an inner floating ring, the opening of the inner floating ring is connected with the collecting container, and the bottom of the inner floating ring is provided with at least two fixed insertion rods which are telescopic rods. The setting of the inner floating ring and the telescopic fixed insertion rod enables the device to adapt to different water depth areas and water level changes, and overcomes the defect that the existing trapping device is limited in applicable fields.

[0017] Further, the space trap is provided with a light-shielding barrel, and the peripheral wall of the space trap is provided with a green LED lamp above the door frame. The light-shielding barrel and the green LED lamp have the function of inducing the apple snail.

[0018] Further, the bottom of the light-shielding barrel is connected with an outer floating ring, and the setting height of the outer floating ring is consistent with that of the inner floating ring. The number of captured apple snails in the collecting container can be determined by observing the water level change of the outer floating ring, and the recycling time of the device can be determined accordingly.

[0019] Further, at least one camera is installed on the inner wall of the light-shielding barrel. The camera can not only record the operation of the device in real time, but also support remote monitoring function. Once a special situation is detected, the user can immediately make scientific adjustment to the device to ensure the stable operation of the device.

[0020] Further, a solar panel is installed on the top of the light-shielding barrel, a storage battery is arranged in the light-shielding barrel, and the storage battery is electrically connected with the solar panel and the electric elements (including a small camera, a pressure sensor and a green LED lamp) respectively. The use of solar power not only has environmental protection and sustainability, but also can effectively reduce the dependence on traditional power, so that the device has significant advantages in energy saving and emission reduction.

[0021] Further, the collecting container is a waterproof cloth bag. The apple snails are collected by the waterproof cloth bag, and the apple snails are isolated from the water environment, so that the apple snails close the operculum due to drought and lose the activity, which can effectively prevent the apple snails from escaping.

[0022] The device has the following beneficial effects:

[0023] 1. The space trap of the present application solves the problem of apple snail adhesion not falling through the design of the movable door structure combined with the reversible door plate and the slidable door sleeve, the device of the present application controls the inside and outside of the movable door through pressure sensing trigger and door sleeve sliding touch switch, and solves the problem that the operation of the movable door is limited by the mass of the apple snail and the trigger threshold.

[0024] 2. The space trap of the device of the present application has the ability to adapt to water level changes, thereby eliminating the need for manual adjustment of device height, widening the scope of application, and significantly improving practicality.

[0025] 3. Based on the living habits of apple snails, the present application ingeniously designs a shading structure and a green LED light source to capture apple snails in an ecological and friendly way, while reducing the risk of water pollution and providing strong technical support for ecological environment protection.

[0026] 4. The present application uses a solar power supply system, which is energy-saving and environmentally friendly, and combines with electric elements to assist the operation of the reversible door, thereby optimizing energy utilization and mechanical action process and improving the stability of the overall operation.

Detailed Implementation

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] Example 1

[0036] A trigger-based, light-induced, continuous snail-catching visual device, such as Figure 1 As shown, it includes a space trap 1, an inner floating ring 2, a fixed insertion rod 3, a collection container 4, a light-blocking bucket 5, an outer floating ring 6, and a solar panel 7.

[0037] The space trap 1 is a hollow, open-bottom regular octagonal prism with a side length of 140mm and a height of 170mm. Each side face has a door frame 11, a movable door 12 installed on the door frame 11, a green LED light 13 positioned above the door frame 11, and a baffle plate 14 positioned at the bottom inside the door frame 11. The baffle plate 14 is described in detail below. Figures 2-3 It is 100mm long and 40mm wide. The movable door 12 is as follows... Figure 4 As shown, the device includes a door panel 121 rotatably connected to the door frame 11 via door hinges 124 on both sides, and a door sleeve 122 fitted onto the bottom of the door panel 121. The door panel 121 is a rectangular plate with a length of 98mm, a width of 65mm, and a thickness of 4mm. It has a pressure sensor inside and a switch 123 at the bottom. The door sleeve 122 is a rectangular sleeve with a length of 100mm, a width of 65mm, and a thickness of 7mm. It is hollow inside, with an opening at one end fitted onto the door panel 121. It has sliding grooves 125 on both sides, through which the door hinges 124 pass. When the apple snail climbs onto the door panel 121, it triggers the pressure sensor to make the door flip inward. At the same time, the door frame 122 slides down, hits and removes the apple snail attached to the door panel 121, and finally completely covers the door panel 121 and touches the bottom switch 123 of the door panel 121 (when flipping inward, the blocking plate 14 blocks and limits the bottom of the door to prevent it from falling out of the door frame 11), making the door flip outward and return to the initial state.

[0038] The inner floating ring 2 is closely connected to the bottom of the space trap 1, which is a regular octagonal ring with a circular opening in the middle, with a side length of 148 mm, an inner circle diameter of 280 mm, and a height of 60 mm. The collection container 4 is arranged below the inner floating ring 2, which is a waterproof cloth bag with an upward opening and a circular plate with a diameter of 280 mm at the bottom, and the opening of the waterproof cloth bag is connected with the circular opening of the inner floating ring 2. The bottom of the inner floating ring 2 is uniformly provided with eight fixed insertion rods 5; the fixed insertion rod 5 includes upper and lower two sections, and the upper section is slidingly connected to the lower section, and when the water level changes, the upper section slides on the lower section under stress, and through the free expansion of the fixed insertion rod 5, the position of the inner floating ring 2 can change with the change of the water level, so that the device can adapt to the change of the water level.

[0039] The light-shielding barrel 5 is arranged on the space trap 1, which is an open-bottomed cylindrical barrel made of light-proof material, with a bottom circle diameter of 600 mm and a height of 250 mm, and the top end of the space trap 1 is fixedly connected with the light-shielding barrel 5. The bottom outer periphery of the light-shielding barrel 5 is connected with an outer floating ring 6, which is a circular ring with an outer circle diameter of 700 mm, an inner circle diameter of 600 mm, and a height of 60 mm, and the setting height of the outer floating ring 6 is consistent with that of the inner floating ring 2.

[0040] As shown in Figure 6 The inner wall of the light-shielding barrel 5 is provided with three small cameras 9, which can be used for recording or remotely monitoring the operation of the device; the inside of the light-shielding barrel 5 is provided with a storage battery 8. The top of the light-shielding barrel 5 is provided with a solar panel 7, and the solar panel 7, small camera 9, pressure sensor, and green led lamp 13 are respectively electrically connected with the storage battery 8. The solar panel 7 receives energy to charge the storage battery 8, and the storage battery 8 supplies power to the small camera 9, pressure sensor, and green led lamp 13. The inside of the light-shielding barrel 5 is also provided with a controller for receiving the signal of the pressure sensor to control the inward turning of the movable door 12, for receiving the signal of the switch 123 to control the turning of the movable door 12 to reset, and for controlling the operation of the small camera 9 and the remote transmission of images.

[0041] The use method of the device of the embodiment is as follows:

[0042] The fixed insertion rod 3 is inserted into the bottom of the colonization water area to fix the device, and the remaining part is floated on the water surface under the action of the inner floating ring 2. The shading area created by the light-shielding barrel 5 can attract apple snails, and the green light of the green led lamp 13 has a significant influence on the feeding behavior of apple snails, which can induce apple snails to climb upward. Since apple snails have the habit of climbing along the stem wall of wetland plants, the fixed insertion rod 3 can provide a climbing path for apple snails to enter the space trap.

[0043] As shown in Figure 5As shown, in the initial state, the door sleeve 122 is below the door panel 121, and the movable door 12 is in the unfolded state. When the apple snail climbs onto the door panel 121 to lay eggs, the pressure sensor is triggered, the door is flipped inside the space trap 1, and the door sleeve 122 slides down under the action of gravity to cover the door panel 121. In the process of sliding down, the apple snail adhering to the door panel 121 is hit, the apple snail retracts into the shell due to instinctive defense, no longer adheres to the door panel 121, and falls into the collection container 4. After the apple snail falls into the collection container 4, there is no obstacle on the door panel 121, the door sleeve 122 continues to slide down until it completely covers the door panel 121, and touches the switch 123 at the bottom of the door panel 121, so that the door is flipped outward, and the movable door 12 returns to the initial state.

[0044] The outer floating ring 6 is at the same horizontal height as the inner floating ring 2. When it is observed that the water level line submerges the outer floating ring 6, it means that the device reaches the maximum capacity, and the recovery device can be used at this time.

[0045] The specific embodiment is only an explanation of the present application, and is not a limitation of the present application. Any change made by a person skilled in the art after reading the specification of the present application will be protected by the patent law as long as it is within the scope of the claims of the present application.
