The second shaft 147 is connected to the rotating shaft 121 in the second toggle component 25, and the induction device 30 includes an extension plate 31 arranged at the end of the positioning ring 11, an induction agent placement groove 32 embedded in the top of the extension plate 31, a plurality of induction tubes 33 horizontally arranged on the top of the extension plate 31, and a switching component 34 arranged at one end of the induction tube 33 close to the extension plate 31, the switching component 34 includes a connecting box 341 arranged on the extension plate 31 and connected to the plurality of induction tubes 33, an arc-shaped slide groove 342 arranged in the connecting box 341, an n-shaped frame 343 arranged in the arc-shaped slide groove 342, and a switch component 34 arranged on the extension plate 31. A plurality of lamp tubes 3431 and a micro fan 3432 are arranged on the outer wall of the n-shaped frame 343, a transmission rod 344 whose one end is connected to the top of the n-shaped frame 343 and the other end is sleeved on the outside of the second shaft 147, an electromagnetic ring 345 is arranged on the top of the transmission rod 344, a third magnetic block 346 is arranged on the outer wall of the n-shaped frame 343, and a third electromagnetic block 347 is embedded in the inner wall of the arc-shaped slide groove 342 and corresponds to the position of the third magnetic block 346, and also includes a refractive component 35 arranged in the induction tube 33, and the refractive component 35 includes a plurality of lenses 351 which are symmetrically arranged on the inner wall of the induction tube 33 and are staggered.

[0037] It should be noted that, in this embodiment, when the device is deployed as a whole, the fixing module can be fixed to the shore by screws, and the capture and counting module is located in the water and is in a semi-submerged state to complete the deployment of the device;

[0038] When catching and counting insects, the attracting device 30 attracts aquatic insects to the entrance of the direct counting device 20, and the second shifting component 25 continuously shifts water into the arc tube 21. When the density of aquatic insects in the water between two adjacent shifting plates 122 is less than a set value, the water passes through the direct shooting area 211, the grid shooting area 212, the second suction area 213 and the diversion area 214 in sequence and then is discharged from the arc tube 21. When the density of aquatic insects in the water between two adjacent shifting plates 122 is greater than a set value, the water passes through the direct shooting area 211, the grid shooting area 212, the second suction area 213 and the diversion area 214 in sequence and enters the expansion counting device 10;

[0039] Furthermore, when the attracting device 30 is working, an attracting agent, such as aquatic insect pheromone, can be placed in the attracting agent placement groove 32, so that aquatic insects can enter the extension plate 31 through the attracting tube 33. When the controller receives the picture information taken by the camera in the direct shooting area 211 and analyzes a plurality of continuous picture information, when the insect density in the picture information continues to exceed the standard value, the trigger switching component 34 sets another attracting tube 33 to the main attracting state;

[0040] Furthermore, when the switching component 34 is working, the electromagnetic ring 345 electromagnetically attracts the second shaft 147, and the second shaft 147 can drive the n-shaped frame 343 to move. When the n-shaped frame 343 moves to coincide with the designated induction tube 33, the electromagnetic ring 345 is powered off. When the n-shaped frame 343 moves to the extreme position, that is, the third magnetic block 346 abuts against the third electromagnetic block 347, the third electromagnetic block 347 can be powered on to generate a repulsive force of the same polarity as the third magnetic block 346, and the n-shaped frame 343 can slide and reset in the arc-shaped slide groove 342. The lamp tube 3431 on the outer wall of the n-shaped frame 343 is convenient for emitting light to attract aquatic insects, and the micro fan 3432 can drive air flow to facilitate the odor of the attractant to be dispersed through the corresponding induction tube 33.

[0041] Furthermore, the lens 351 can continuously refract the light emitted by the lamp tube 3431 so that the light can be transmitted through the induction tube 33 corresponding to the lamp tube 3431 to attract aquatic insects;

[0042] Furthermore, cameras are installed on the top of the inner wall of the direct shooting area 211, the grid shooting area 212 and the water absorption counting area 112;

[0043] Furthermore, when the driving component 14 is working, the driving motor 145 drives the reducer 144 to work, the output end of the reducer 144 drives the first gear 142 to rotate, the first gear 142 drives the two second gears 143 to rotate, the first gear 142 drives the first shifting component 12 to rotate through the first shaft 146, and the second gear 143 drives the second shifting component 25 to rotate through the second shaft 147;

[0044] Furthermore, the diameter ratio of the positioning ring 11 and the arc tube 21 can be made reciprocal to the diameter ratio of the first gear 142 and the second gear 143 so that water between two adjacent paddles 122 in the second paddle component 25 can flow from the diversion area 214 into the space between the two paddles 122 in the first paddle component 12 in the expansion area 111 .

[0045] Please refer to the attached Figure 3 , 6 As shown, in another preferred embodiment of the present invention, the expansion counting device 10 includes a positioning ring 11 whose outer wall is connected to the fixed module through a connecting rod, a first toggle component 12 arranged at the inner ring of the positioning ring 11 and whose execution end extends into the positioning ring 11, two expansion areas 111, a water absorption counting area 112 and a first suction removal area 113 symmetrically arranged in the positioning ring 11, and a water absorption component 13 arranged at the bottom of the water absorption counting area 112 and connected to the water absorption counting area 112; the water absorption component 13 includes a first installation box 131 arranged at the bottom of the water absorption counting area 112, and a plurality of water absorption ports 131 connected to the bottom of the water absorption counting area 112 at the top and connected to the top of the first installation box 131 at the bottom. 2. A sponge pad 133 is arranged at the top of the inner wall of the first installation box 131 and the top extends to the water suction port 132, a lifting plate 134 is slidably connected to the inner wall of the first installation box 131 and the top is connected to the bottom of the sponge pad 133, a first magnetic block 135 is arranged at the bottom of the lifting plate 134, and a first electromagnetic block 136 is arranged at the bottom of the inner wall of the first installation box 131 and abuts against the first magnetic block 135, the first toggle component 12 includes a rotating shaft 121 rotatably connected to the inner ring of the positioning ring 11, a plurality of toggle plates 122 are arranged in an annular array on the outer wall of the rotating shaft 121 and located in the positioning ring 11, and the second toggle component 25 has the same structure as the first toggle component 12.

[0046] It should be noted that, in the present embodiment, after the water enters the positioning ring 11, the paddle 122 in the first paddle component 12 sequentially paddles the water through the expansion area 111, the water absorption counting area 112 and the first suction area 113. When the water passes through the water absorption counting area 112, the water absorption component 13 absorbs the liquid, and the camera in the water absorption counting area 112 takes pictures of the insects and transmits the picture information to the controller. The controller receives the picture information and counts the insects after analysis. After the camera in the water absorption counting area 112 completes the shooting, the water absorption component 13 squeezes the absorbed water into the water absorption counting area 112 again. After the water reaches the first suction area 113, it is sucked and collected by the suction component 24.

[0047] Furthermore, when the water absorbing component 13 is working, the first electromagnetic block 136 is energized to generate a repulsive force of the same polarity or a suction force of the opposite polarity as the first magnetic block 135. The repulsive force pushes the lifting plate 134 to move upward, and the suction force drives the lifting plate 134 to move downward. When the lifting plate 134 moves upward, the sponge pad 133 is squeezed, and water is discharged through the water suction port 132. The lifting plate 134 descends, and the sponge pad 133 can absorb water through the water suction port 132.

[0048] Please refer to the attached Figure 3 , 5 As shown, in another preferred embodiment of the present invention, the direct counting device 20 includes an arc tube 21 arranged on the outer wall of the positioning ring 11, a second toggle component 25 arranged on the inner ring of the arc tube 21, a direct shooting area 211, a grid shooting area 212, a second suction area 213 and a diversion area 214 arranged in the arc tube 21 in sequence along the insect entry direction, a magnetic grid component 22 arranged at the bottom of the grid shooting area 212, and a magnetic grid component 22 arranged at the top of the diversion area 214 and having an execution end extending to the diversion area 21 4, the diversion area 214 is connected to the expansion area 111, the magnetic dynamic grid component 22 includes a second installation box 221 arranged at the bottom of the grid shooting area 212 and connected to the grid shooting area 212, a rubber sheet 222 arranged at the top of the second installation box 221, a plurality of compartments 223 arranged in the second installation box 221, a second electromagnetic block 224 arranged at the bottom of the inner wall of the compartment 223, a sliding connection with the inner wall of the compartment 223 and abutting against the second electromagnetic block 224 The second magnetic block 225 is connected to the second magnetic block 225, and the upper top plate 226 is arranged on the top of the second magnetic block 225. The diverter component 23 includes a first valve plate assembly 231 arranged on the top of the diverter area 214, and a second valve plate assembly 232 arranged between the diverter area 214 and the expansion area 111. The first valve plate assembly 231 includes a valve body 2311 arranged on the top of the diverter area 214 and the bottom of which is connected to the diverter area 214, a movable valve plate 2312 arranged in the valve body 2311, and a second valve plate assembly 232 arranged between the diverter area 214 and the expansion area 111. The electric cylinder 2313 at the top of 311 and the execution end passes through the valve body 2311 and is connected to the movable valve plate 2312. The second valve plate assembly 232 has the same structure as the first valve plate assembly 231, and also includes a suction component 24 whose suction end is connected to the first suction area 113 and the second suction area 213. The suction component 24 includes an electric control valve 241 whose suction end is connected to the first suction area 113 and the second suction area 213 through a pipeline, and a negative pressure pipe 242 whose one end is connected to the discharge end of the electric control valve 241.

[0049] It should be noted that, in this embodiment, when the direct counting device 20 is working, the paddle 122 in the second paddle component 25 paddles the water into the arc tube 21, and the water between two adjacent paddles 122 passes through the direct shooting area 211, the grid shooting area 212, the second suction area 213 and the diversion area 214;

[0050] The camera in the direct shooting area 211 captures image information and transmits it to the controller, which performs image analysis and counts. When the insect density is zero, the grid shooting area 212, the second suction area 213, and the diversion area 214 all have no action and water is discharged from the arc tube 21;

[0051] When the insect density is less than the set density and can be clearly photographed, the second suction area 213 sucks the insects;

[0052] When the insect density is less than the set density but cannot be clearly photographed, the magnetic grid component 22 at the bottom of the grid shooting area 212 starts to work as a grid, so as to divide the area, so that the camera in the grid shooting area 212 can take picture information and transmit it to the controller, and the controller receives the picture information and counts it after analysis. After completion, the second suction area 213 sucks the insects;

[0053] When the insect density is greater than the set density, the gridded shooting area 212 and the second suction area 213 do not move, and the diversion component 23 starts to work to guide the water in the diversion area 214 into the expansion area 111 in the expansion counting device 10;

[0054] Furthermore, when the magnetically movable grid component 22 is working, the second electromagnetic block 224 is energized to generate a repulsive force of the same polarity as the second magnetic block 225. The second magnetic block 225 drives the upper top plate 226 to move upward under the push of the repulsive force. The multiple upper top plates 226 move upward at the same time to lift up the rubber sheet 222 and form a grid shape.

[0055] Furthermore, when the diverter component 23 is working, the first valve plate assembly 231 is opened and the second valve plate assembly 232 is closed, and the water is discharged through the discharge end of the arc tube 21. When the first valve plate assembly 231 is closed and the second valve plate assembly 232 is opened, the water enters the expansion area 111 through the second valve plate assembly 232. The working principle of the second valve plate assembly 232 is consistent with that of the first valve plate assembly 231. Taking the working of the first valve plate assembly 231 as an example, the actuator end of the electric cylinder 2313 drives the valve plate 2312 to rise and fall to realize opening and closing.

[0056] Furthermore, when the suction component 24 is working, a negative pressure system can be set in the fixed module and connected to the negative pressure pipe 242. After the electric control valve 241 is opened, the insects in the first suction area 113 and the second suction area 213 can be sucked away through the negative pressure pipe 242.

[0057] The working principle of the present invention is:

[0058] The electrical components in the present invention are all triggered to operate by the PLC controller, and the PLC controller can exchange data with the control center;

[0059] When the device is deployed as a whole, the fixed module can be fixed on the shore by screws, and the capture counting module is located in the water and is in a semi-submerged state to complete the deployment of the device;

[0060] When catching and counting insects, the attracting device 30 attracts aquatic insects to the entrance of the direct counting device 20, and the second shifting component 25 continuously shifts water into the arc tube 21. When the density of aquatic insects in the water between two adjacent shifting plates 122 is less than a set value, the water passes through the direct shooting area 211, the grid shooting area 212, the second suction area 213 and the diversion area 214 in sequence and then is discharged from the arc tube 21. When the density of aquatic insects in the water between two adjacent shifting plates 122 is greater than a set value, the water passes through the direct shooting area 211, the grid shooting area 212, the second suction area 213 and the diversion area 214 in sequence and enters the expansion counting device 10;

[0061] When the attracting device 30 is working, an attracting agent, such as aquatic insect pheromone, can be placed in the attracting agent placement groove 32, so that aquatic insects can enter the extension plate 31 through the attracting tube 33. When the controller receives the picture information taken by the camera in the direct shooting area 211 and analyzes a plurality of continuous picture information, when the insect density in the picture information continues to exceed the standard value, the trigger switching component 34 sets another attracting tube 33 to the main attracting state;

[0062] When the switching component 34 is working, the electromagnetic ring 345 electromagnetically attracts the second shaft 147, and the second shaft 147 can drive the n-shaped frame 343 to move. When the n-shaped frame 343 moves to coincide with the designated induction tube 33, the electromagnetic ring 345 is powered off. When the n-shaped frame 343 moves to the limit position, that is, the third magnetic block 346 abuts against the third electromagnetic block 347, the third electromagnetic block 347 can be powered on to generate a repulsive force of the same polarity as the third magnetic block 346, and the n-shaped frame 343 can slide and reset in the arc-shaped slide groove 342. The lamp tube 3431 on the outer wall of the n-shaped frame 343 is convenient for emitting light to attract aquatic insects, and the micro fan 3432 can drive air flow to facilitate the odor of the attractant to be dispersed through the corresponding induction tube 33.

[0063] The lens 351 can continuously refract the light emitted by the lamp tube 3431 so that the light can be transmitted through the induction tube 33 corresponding to the lamp tube 3431 to attract aquatic insects;

[0064] Cameras are installed on the top of the inner wall of the direct shooting area 211, the grid shooting area 212 and the water absorption counting area 112;

[0065] When the driving component 14 is working, the execution end of the driving motor 145 drives the reducer 144 to work, the output end of the reducer 144 drives the first gear 142 to rotate, the first gear 142 drives the two second gears 143 to rotate, the first gear 142 drives the first shifting component 12 to rotate through the first shaft 146, and the second gear 143 drives the second shifting component 25 to rotate through the second shaft 147;

[0066] The diameter ratio of the positioning ring 11 and the arc tube 21 can be made reciprocal to the diameter ratio of the first gear 142 and the second gear 143, so that the water between two adjacent paddles 122 in the second paddle component 25 flows from the diversion area 214 to the space between the two paddles 122 in the first paddle component 12 in the expansion area 111;

[0067] When the direct counting device 20 is working, the paddle 122 in the second paddle component 25 paddles the water into the arc tube 21, and the water between two adjacent paddles 122 passes through the direct shooting area 211, the grid shooting area 212, the second suction area 213 and the diversion area 214;

[0068] The camera in the direct shooting area 211 captures image information and transmits it to the controller, which performs image analysis and counts. When the insect density is zero, the grid shooting area 212, the second suction area 213, and the diversion area 214 all have no action and water is discharged from the arc tube 21;

[0069] When the insect density is less than the set density and can be clearly photographed, the second suction area 213 sucks the insects;

[0070] When the insect density is less than the set density but cannot be clearly photographed, the magnetic grid component 22 at the bottom of the grid shooting area 212 starts to work as a grid, so as to divide the area, so that the camera in the grid shooting area 212 can take picture information and transmit it to the controller, and the controller receives the picture information and counts it after analysis. After completion, the second suction area 213 sucks the insects;

[0071] When the insect density is greater than the set density, the gridded shooting area 212 and the second suction area 213 do not move, and the diversion component 23 starts to work to guide the water in the diversion area 214 into the expansion area 111 in the expansion counting device 10;

[0072] When the magnetic mesh component 22 is working, the second electromagnetic block 224 is energized to generate a repulsive force of the same polarity as the second magnetic block 225. The second magnetic block 225 drives the upper top plate 226 to move upward under the push of the repulsive force. Multiple upper top plates 226 move upward at the same time to lift up the rubber sheet 222 and form a mesh shape.

[0073] When the flow splitting component 23 is working, if the first valve plate assembly 231 is opened and the second valve plate assembly 232 is closed, the water body is discharged from the discharge end of the arc-shaped pipe 21. If the first valve plate assembly 231 is closed and the second valve plate assembly 232 is opened, the water body enters the expansion area 111 through the second valve plate assembly 232. The working principle of the second valve plate assembly 232 is the same as that of the first valve plate assembly 231. Taking the working of the first valve plate assembly 231 as an example, the execution end of the electric cylinder 2313 drives the moving valve plate 2312 to lift and lower to achieve opening and closing;

[0074] When the suction component 24 is working, a negative pressure system can be set in the fixed module and communicated with the negative pressure pipe 242. After the electric control valve 241 is opened, the insects in the first suction area 113 and the second suction area 213 can be sucked out through the negative pressure pipe 242;

[0075] After the water body enters the positioning ring 11, the dial plate 122 in the first dialing component 12 sequentially dials the water body through the expansion area 111, the water absorption counting area 112, and the first suction area 113. When the water body passes through the water absorption counting area 112, the water absorption component 13 sucks the liquid. The camera in the water absorption counting area 112 takes pictures of the insects and transmits the picture information to the controller. The controller receives the picture information and counts after analysis. After the camera in the water absorption counting area 112 finishes taking pictures, the water absorption component 13 squeezes the adsorbed water body back into the water absorption counting area 112. After the water body reaches the first suction area 113, it is sucked and collected by the suction component 24;

[0076] When the water absorption component 13 is working, the first electromagnet 136 is energized to generate a repulsive force of the same sex or an attractive force of the opposite sex with the first magnet 135. The repulsive force pushes the lifting plate 134 to move upward, and the attractive force drives the lifting plate 134 to move downward. When the lifting plate 134 moves upward, the sponge pad 133 is squeezed, and the water is discharged through the water absorption port 132. When the lifting plate 134 moves downward, the sponge pad 133 can absorb water through the water absorption port 132.
