Description

Technical Field

[0001] The present invention relates to the technical field of biological protection, and particularly relates to a research and protection trapping device for small marine animals. Background Art

[0002] Small marine animals (such as benthic animals and juvenile fish) are an important part of the marine ecosystem. The research on their population dynamics, behavior patterns and ecological functions is crucial for understanding the marine ecological mechanism. However, due to the strong activity ability of small marine animals, it is difficult to capture them, and it is not easy to obtain them.

[0003] The existing trapping devices usually consist of a trapping cylinder and a cover plate. By means of sonar trapping, light trapping and trapping agent trapping, etc., small marine animals are attracted into the trapping cylinder, and then the trapping cylinder is quickly closed to capture them. However, when the existing trapping cylinder is closed, due to the large closing action of the cover plate, it is very easy to scare small marine animals, resulting in the failure of capture, and even causing stress reactions in small marine animals.

[0004] In summary, how to solve the problem that when the existing trapping cylinder is closed, due to the large closing action of the cover plate, it is very easy to scare small marine animals, resulting in the failure of capture, and even causing stress reactions in small marine animals has become a difficult problem that needs to be solved urgently in the current field. Therefore, it is necessary to propose a more reasonable research and protection trapping device for small marine animals. Summary of the Invention

[0005] To solve the above problems, the present invention provides a research and protection trapping device for small marine animals. Through the design of the trapping component, during the trapping process, the impact of the device on small marine animals can be greatly reduced, the capture success rate can be improved, and the risk of stress reactions in small marine animals can be reduced.

[0006] To achieve the above object, the technical solution of the present invention is as follows: A research and protection trapping device for small marine animals includes a trapping cylinder. A support rod is fixedly connected to the inner bottom of the trapping cylinder, and a central platform is fixedly connected to the top of the support rod. A trapping component for trapping small marine animals is provided on the central platform. A recognition component for recognizing small marine animals is provided at the bottom of the central platform.

[0007] The trapping component includes a plurality of rotating rods rotatably connected to the side wall of the central platform. A plurality of rotating plates are coaxially and fixedly connected to the rotating rods. A plurality of arc-shaped grooves are formed in the inner side wall of the trapping cylinder. A plurality of arc-shaped frames are slidably arranged in the arc-shaped grooves. The arc-shaped grooves are located on both sides of the adjacent rotating plates, and the arc-shaped frames are fixedly connected to the adjacent rotating plates. Trapping agents are stored in the arc-shaped frames. A driving component for driving the rotating rods to rotate is provided outside the trapping cylinder.

[0008] The outer sidewall of the trapping cylinder is provided with a guiding component for guiding the swimming of small marine animals and a recovery component for recovering the trapping cylinder; the bottom of the trapping cylinder is provided with an attracting component for further attracting small marine animals and a loading component for loading small marine animals.

[0009] The technical principle of the above solution is as follows:

[0010] In the initial state, the rotating plate is in a horizontal state; after the trapping cylinder sinks to the designated position, the driving component drives the rotating rod to rotate forward, and the rotating rod will drive the rotating plate to rotate forward, so that the rotating plate changes from a horizontal state to a vertical state; during this process, the arc-shaped frame will slide out of the arc-shaped groove under the drive of the rotating plate, releasing the trapping agent, and at the same time, the attracting component is used to attract small marine animals together. At this time, small marine animals can enter the trapping cylinder through the gap between the rotating plates.

[0011] When the recognition component recognizes that the target organism enters the interior of the trapping cylinder, the driving component will drive the rotating rod to rotate in reverse, and the rotating rod will drive the rotating plate to rotate. The rotating plate will change from a vertical state to a horizontal state, so that adjacent rotating plates fit together, thereby sealing the trapping cylinder.

[0012] The guiding component will guide the target organism into the loading component, thereby loading the target organism; after the capture is completed, the trapping cylinder can be recovered through the recovery component.

[0013] Adopting the above solution has the following beneficial effects:

[0014] 1. For the trapping devices in the prior art, in order to prevent small marine animals from escaping, when small marine animals enter the trapping device, the cover plate needs to be quickly closed; however, due to the relatively large volume of the cover plate in the prior art, when the cover plate is closed, it is easy to cause violent disturbance of the water flow in the device, scaring small marine animals, resulting in capture failure or causing stress reactions in small marine animals; compared with the prior art, the present invention seals the trapping cylinder by the rotation of several rotating plates. The rotating plates are small in volume, and the water flow fluctuations caused by their rotation are extremely slight, thereby greatly improving the capture success rate. At the same time, the risk of stress reactions in small marine animals is reduced, and the protection degree of small marine animals is improved.

[0015] 2. In the prior art, during the closing process of the cover plate and the trapping cylinder, due to the relatively large opening of the trapping cylinder, it takes a long time for the cover plate to completely seal the trapping cylinder, resulting in small marine animals escaping before the cover plate and the trapping cylinder are completely sealed; compared with the prior art, through the design of several rotating plates in the present invention, while ensuring that small marine animals can enter the trapping cylinder, by the simultaneous rotation of several rotating plates, the rotating plates can quickly seal the trap, greatly reducing the probability of small marine animals escaping and effectively improving the capture success rate.

[0016] 3. By adjusting the angle of the rotating plate, the present invention can quickly adjust the gap between the rotating plates, so as to capture marine animals of different body sizes. At the same time, it can also prevent most large-sized organisms from entering the trapping cylinder and preying on small marine animals, which affects the normal progress of the trapping work.

[0017] Furthermore, one ends of the rotating rods far away from the central platform all extend outside the trapping cylinder and are all fixedly connected with rotating blocks. The driving assembly includes a controller and a mounting bracket fixedly connected to the outer side wall of the trapping cylinder. A driving member is fixedly connected to the mounting bracket, and the output shaft of the driving member is coaxially and fixedly connected with the adjacent rotating block; several hinge rods are arranged outside the trapping cylinder, and both ends of each hinge rod are hinged to the adjacent rotating block; the controller is used to control the operation of the driving member, and then drive the rotating block to rotate.

[0018] Beneficial effects: By starting the driving member through the controller, the output shaft of the driving member will drive the rotating block to rotate. The rotating block will drive the adjacent rotating block to rotate through the hinge rod, and then drive all the rotating blocks and rotating rods to rotate. The rotating rod will drive the rotating plate to rotate around the rotating rod as the center of the circle, so as to adjust the rotation angles of all the rotating plates at the same time.

[0019] Furthermore, the guiding assembly includes a first piston box and a second piston box fixedly connected to both sides of the mounting bracket; a first piston plate and a second piston plate are respectively slidably matched horizontally in the first piston box and the second piston box; a first piston rod and a second piston rod are hinged to the rotating block on the output shaft of the driving member. The first piston rod extends into the first piston box and is hinged to the first piston plate, and the second piston rod extends into the second piston box and is hinged to the second piston plate; several first holes and second holes are respectively opened in the lower part and the upper part of the trapping cylinder; the first holes and the second holes are respectively communicated with the first piston box and the second piston box; the first piston box also stores trapping agents.

[0020] Beneficial effects: When the trapping cylinder sinks to the designated position, when the output shaft of the driving member drives the rotating block to rotate, the first piston rod will push the first piston plate to slide in the first piston box, so as to transfer the trapping agent in the first piston box into the trapping cylinder through the first hole; at the same time, the second piston rod will pull the second piston plate to slide in the second piston box, so as to suck part of the seawater passing through the second hole into the second piston box for storage.

[0021] When capturing a target organism, the output shaft of the driving member drives the rotating block to rotate in the reverse direction. At this time, the first piston rod drives the first piston plate to slide in the first piston chamber, causing the first piston chamber to suck the seawater in the lower part of the trapping cylinder through the first hole. At the same time, the second piston rod pulls the second piston plate to slide in the second piston chamber, thereby releasing the seawater stored in the second piston chamber to the upper part of the trapping cylinder through the second hole. At this time, the pressure in the upper part of the trapping cylinder increases, and the pressure in the lower part of the trapping cylinder decreases. The target organism will be guided to flow towards the inner bottom wall of the trapping cylinder, thereby reducing the probability of the target organism escaping and increasing the capture success rate.

[0022] Further, the recognition component includes a camera fixedly connected to the bottom of the central platform. The controller is used to receive the images collected by the camera and control the operation of the driving member based on the images collected by the camera.

[0023] Beneficial effect: After the camera captures an image of the target organism, the controller will immediately control the driving member to operate and close the trapping cylinder, thereby capturing the target organism.

[0024] Further, the attraction component includes a sound wave emitter fixedly connected to the side wall of the support rod. The controller is used to control the operation of the sound wave emitter.

[0025] Beneficial effect: The sound wave emitter can emit sound waves for attracting the target organism, thereby luring the target organism into the trapping cylinder for easy capture.

[0026] Further, the loading component includes a loading frame fixedly connected and communicating with the outer side wall of the trapping cylinder. A control valve is connected and communicated at the connection between the two. The controller is used to control the operation of the control valve; a plurality of mounting holes are opened on the side of the loading frame away from the trapping cylinder, and fan blades are installed in the mounting holes; the loading frame communicates with the first piston chamber.

[0027] Beneficial effect: After the camera identifies the target organism, the controller will open the control valve while starting the driving member. Since the loading frame communicates with the first piston chamber, when capturing the target organism, the first piston chamber will suck the seawater in the loading frame. At this time, the seawater will flow from the trapping cylinder to the loading frame, thereby guiding the target organism from the trapping cylinder to the loading frame; during the flow of the seawater, the fan blades will also rotate under the impact of the seawater, thereby further improving the fluidity of the seawater, enhancing the guiding effect of the seawater on the target organism, and also keeping the seawater inside the loading frame flowing, optimizing the loading environment of the target organism and improving the protection of the target organism; when the camera identifies that at least 3 target organisms enter the loading frame, the controller will immediately close the control valve to prevent the target organism from escaping; at the same time, it is also convenient for subsequent continuous capture operations.

[0028] Further, a plurality of trapping lights are fixedly connected inside the loading frame.

[0029] Beneficial effects: During the guiding process, the control valve remains open, enabling the trapping cylinder to communicate with the loading frame. Utilizing the phototaxis of some organisms, the trapping lamp can attract small marine animals to actively enter the loading frame, thereby increasing the success rate of capture.

[0030] Furthermore, fixing rods are fixedly connected to the bottoms of the rotating blocks, and the bottoms of the fixing rods are all conical.

[0031] Beneficial effects: When the trapping cylinder sinks to the designated position, when the output shaft of the driving member drives the rotating block to rotate, the rotating block will drive the fixing rods to rotate synchronously. Since the bottoms of the fixing rods are all conical, the bottoms of the fixing rods will insert into the seabed, thereby fixing the device and preventing the device from deviating from the designated position due to the impact of seawater.

[0032] Furthermore, the recovery assembly includes a winch, and a plurality of towing ropes are fixedly connected to the winch. The bottoms of the towing ropes are all fixedly connected to the outer sidewall of the trapping cylinder; the controller is used to control the operation of the winch, thereby controlling the lifting of the trapping cylinder.

[0033] Beneficial effects: After completing the trapping task, the operator can retract the towing ropes through the winch, thereby recycling the trapping cylinder. At the same time, the loading cylinder can be opened to obtain the target organisms.

[0034] Furthermore, sealing gaskets are fixedly connected to the sidewalls of the rotating plates.

[0035] Beneficial effects: The sealing gaskets can further improve the sealing effect of the rotating plates on the trapping cylinder, thereby increasing the success rate of trapping.

[0036] The additional aspects and advantages of the present invention will be partly given in the following description, partly will become apparent from the following description, or will be understood through the practice of the present invention. Description of the Drawings

Detailed implementation manners

[0043] The following is a further detailed description through specific implementation manners:

[0044] Embodiment 1:

[0045] As shown in the Figures 1-5 accompanying drawings: A small marine animal research and protection trapping device includes a trapping cylinder 1. A support rod 2 is welded to the inner bottom of the trapping cylinder 1, and a central platform 3 is welded to the top of the support rod 2; A trapping assembly for trapping small marine animals is provided on the central platform 3; A recognition assembly for recognizing small marine animals is provided at the bottom of the central platform 3.

[0046] The trapping assembly includes a plurality of rotating rods 4 rotatably connected to the side wall of the central platform 3. A plurality of rotating plates 5 are coaxially fixedly clamped on each rotating rod 4; A plurality of arc grooves 6 are formed in the inner side wall of the trapping cylinder 1, and a plurality of arc frames 7 are slidably arranged in the arc grooves 6. The arc grooves 6 are located on both sides of the adjacent rotating plates 5, and the arc frames 7 are welded to the adjacent rotating plates 5; Trapping agents are stored in each arc frame 7; A driving assembly for driving the rotating rod 4 to rotate is provided outside the trapping cylinder 1.

[0047] During the trapping process, the rotating rod 4 is driven to rotate by the driving assembly. Since the rotating rod 4 is fixedly clamped with the rotating plate 5, the rotating rod 4 will drive the rotating plate 5 to rotate. A plurality of rotating plates 5 are mutually attached to form a cover plate for sealing the trapping cylinder 1, thereby sealing the trapping cylinder 1 to capture the target organism; Since the rotating plate 5 is smaller in volume than the cover plates in the prior art (each cover plate can be divided into a plurality of rotating plates 5), the water flow fluctuation caused by its rotation is extremely slight, which can greatly reduce the impact of the device on small marine animals, improve the success rate of capture, and reduce the risk of stress reaction of small marine animals.

[0048] Sealing gaskets are fixedly adhered to the side walls of the rotating plates 5, and the sealing gaskets can improve the sealing effect of the rotating plates 5 on the trapping cylinder 1 and improve the success rate of trapping.

[0049] The outer sidewall of the trapping cylinder 1 is provided with a guiding assembly for guiding the swimming of small marine animals and a recovery assembly for recovering the trapping cylinder 1; the bottom of the trapping cylinder 1 is provided with an attracting assembly for further attracting small marine animals and a loading assembly for loading small marine animals.

[0050] One ends of the rotating rods 4 away from the central platform 3 all extend outside the trapping cylinder 1 and are all welded with rotating blocks 8. The driving assembly includes a controller and a mounting frame 9 bolted to the outer sidewall of the trapping cylinder 1. A driving member is bolted to the mounting frame 9, and the output shaft of the driving member is coaxially bolted to the adjacent rotating block 8; several hinge rods 10 are arranged outside the trapping cylinder 1, and both ends of the hinge rods 10 are hinged to the adjacent rotating blocks 8; the controller is used to control the operation of the driving member, thereby driving the rotation of the rotating block 8.

[0051] The guiding assembly includes a first piston box 11 and a second piston box 12 welded and fixed to both sides of the mounting frame 9; a first piston plate 13 and a second piston plate 14 are respectively slidably fitted horizontally in the first piston box 11 and the second piston box 12; a first piston rod 15 and a second piston rod 16 are hinged to the rotating block 8 on the output shaft of the driving member. The first piston rod 15 extends into the first piston box 11 and is hinged to the first piston plate 13, and the second piston rod 16 extends into the second piston box 12 and is hinged to the second piston plate 14; several first holes 17 and second holes 18 are respectively formed in the lower part and the upper part of the trapping cylinder 1; the first holes 17 and the second holes 18 are respectively communicated with the first piston box 11 and the second piston box 12; the first piston box 11 also stores a trapping agent.

[0052] Since both the first piston rod 15 and the second piston rod 16 are hinged to the rotating block 8, when the rotating block 8 rotates, it will drive the first piston rod 15 and the second piston rod 16 to move left and right, thereby driving the first piston plate 13 and the second piston plate 14 to slide horizontally in the first piston box 11 and the second piston box 12 respectively, so as to release the trapping agent and simultaneously suck the seawater in the trapping cylinder 1, guide the flowing direction of the seawater, and then guide the moving direction of the marine animals.

[0053] The recognition assembly includes a camera 19 bolted to the bottom of the central platform 3. The controller is used to receive the images collected by the camera 19 and control the operation of the driving member based on the images collected by the camera 19.

[0054] The attracting assembly includes a sound wave emitter 20 screwed to the sidewall of the support rod 2. The controller is used to control the operation of the sound wave emitter 20.

[0055] The loading component includes a loading frame 21 welded and fixed to the outer side wall of the trapping cylinder 1, and a control valve 22 is connected at the connection between the two. The controller is used to control the operation of the control valve 22; a number of mounting holes are provided on the side of the loading frame 21 away from the trapping cylinder 1, and fan blades 23 are installed in the mounting holes; the loading frame 21 is connected to the first piston box 11.

[0056] The recovery component includes a winch (not shown in the figure, the winch can be installed on an offshore operation platform, a ship, and the shore. In this embodiment, the winch is installed on the offshore operation platform), and a number of towing ropes 26 are fixedly adhered to the winch. The bottoms of the towing ropes 26 are fixedly adhered to the outer side wall of the trapping cylinder 1; the controller is used to control the operation of the winch, and thus control the lifting and lowering of the trapping cylinder 1.

[0057] Since the winch is fixedly adhered to the towing rope 26, and the towing rope 26 is fixedly adhered to the outer side wall of the trapping cylinder 1; when the winch is started, the operator can quickly retract the entire device to the offshore operation platform.

[0058] In this embodiment, the driving member is selected as an AC motor 27.

[0059] The specific implementation process is as follows:

[0060] In the initial state, the rotating plate 5 is in a horizontal state ( Figure 1 in which the rotating plate 5 is in a vertical state), the operator starts the winch through the controller, sinks the trapping cylinder 1 to the designated position, and then starts the AC motor 27 through the controller.

[0061] Taking Figure 1 and Figure 2 as an example, the output shaft of the AC motor 27 will drive the rotating block 8 to rotate clockwise with the rotating rod 4 as the center. The rotating block 8 will drive the adjacent rotating block 8 to rotate through the hinge rod 10, and then drive all the rotating blocks 8 and the rotating rod 4 to rotate clockwise. The rotating rod 4 will drive the rotating plate 5 to rotate clockwise with the rotating rod 4 as the center, so as to simultaneously adjust the rotation angles of all the rotating plates 5, making the rotating plate 5 change from a horizontal state to a vertical state (as shown in Figure 1 ), and at this time, the gap between the adjacent rotating plates 5 increases; during this process, the arc-shaped frame 7 will slide out of the arc-shaped groove 6 under the drive of the rotating plate 5, release the trapping agent, and at the same time use the sound wave emitter 20 to emit sound waves for attracting the target organisms, so as to attract the target organisms. At this time, the target organisms can enter the trapping cylinder 1 from the gap between the rotating plates 5.

[0062] After the camera 19 captures that the target organism enters the trapping cylinder 1, the controller will start the AC motor 27 again. The output shaft of the AC motor 27 will drive the rotating block 8 to rotate counterclockwise around the rotating rod 4, and the rotating rod 4 will drive the rotating plate 5 to rotate counterclockwise. The rotating plate 5 will change from the vertical state to the horizontal state, so that adjacent rotating plates 5 are mutually attached, thereby sealing the trapping cylinder 1.

[0063] Take Figure 1 and Figure 2 as an example. When the trapping cylinder 1 sinks to the designated position, when the output shaft of the AC motor 27 drives the rotating block 8 to rotate clockwise, the rotating block 8 will push the first piston rod 15 and the first piston plate 13 to move leftward in the first piston chamber 11, thereby transferring the trapping agent in the first piston chamber 11 to the trapping cylinder 1 through the first hole 17; at the same time, the rotating block 8 will pull the second piston rod 16 and the second piston plate 14 to slide leftward in the second piston chamber 12, thereby sucking part of the seawater into the second piston chamber 12 through the second hole 18 for storage.

[0064] When capturing the target organism, the output shaft of the AC motor 27 will drive the rotating block 8 to rotate counterclockwise. At this time, the first piston rod 15 will drive the first piston plate 13 to slide rightward in the first piston chamber 11, so that the first piston chamber 11 sucks the seawater in the lower part of the trapping cylinder 1 through the first hole 17. At the same time, the second piston rod 16 will push the second piston plate 14 to slide rightward in the second piston chamber 12, thereby releasing the seawater stored in the second piston chamber 12 to the upper part of the trapping cylinder 1 through the second hole 18. At this time, the pressure in the upper part of the trapping cylinder 1 increases, and the pressure in the lower part of the trapping cylinder 1 decreases. The seawater will flow downward in the trapping cylinder 1, and the target organism will be guided to the bottom wall of the trapping cylinder 1 along with the flow of the seawater. Since the rotating plate 5 is located in the upper part of the trapping cylinder 1, the gap between the rotating plates 5 is also located in the upper part of the trapping cylinder 1, and this position is the only exit for the target organism to escape (in this embodiment, the aperture of the installation hole is much smaller than the size of the target organism to prevent the target organism from escaping through the installation hole); by guiding the target organism to the lower part of the trapping cylinder 1, the probability of the target organism escaping can be reduced, and the capture success rate can be improved.

[0065] Take Figure 4For example, after the camera 19 recognizes the target organism, the controller will open the control valve 22 while starting the AC motor 27 for the second time, making the trapping cylinder 1 communicate with the loading frame 21. Since the loading frame 21 communicates with the first piston box 11, when capturing the target organism, the first piston box 11 will suck the seawater in the loading frame 21, reducing the pressure in the loading frame 21. At this time, the seawater will flow from the trapping cylinder 1 to the loading frame 21, thus guiding the target organism from the trapping cylinder 1 into the loading frame 21. During the flow of the seawater, the fan blades 23 will also rotate under the impact of the seawater, further improving the fluidity of the seawater, accelerating the flow of the seawater in the loading frame 21, further reducing the pressure in the loading frame 21, enhancing the guiding effect on the target organism, and at the same time keeping the seawater inside the loading frame 21 flowing, optimizing the loading environment of the target organism and enhancing the protection of the target organism. When the camera 19 recognizes that at least 3 (which can be adjusted according to actual needs) target organisms enter the loading frame 21, the controller will immediately close the control valve 22 to prevent the target organisms from escaping; at the same time, it is also convenient for the trapping cylinder 1 to perform subsequent multiple captures.

[0066] As Figure 5 shown, in this embodiment, a number of strip-shaped holes are formed in the side wall of the loading frame 21, and release nets for the strips are fixedly adhered to the strip-shaped holes, allowing various small marine animals to pass through (such as Chinese horseshoe crabs and seahorses), etc.

[0067] After the capture is completed, the operator starts the winch through the controller, and the trapping cylinder 1 will be accurately recovered by the operator under the traction of the traction rope 26.

[0068] Embodiment 2:

[0069] As shown in the Figure 1 and Figure 2 figures, different from the above embodiment, a number of trapping lights 24 are fixedly adhered inside the loading frame 21.

[0070] The specific implementation process is as follows: During the guiding process, the control valve 22 remains open, making the trapping cylinder 1 communicate with the loading frame 21. Utilizing the phototaxis of some organisms, the trapping lights 24 can attract small marine animals to actively enter the loading frame 21, improving the success rate of capture.

[0071] Embodiment 3:

[0072] As shown in the Figure 1 and Figure 2 figures, different from the above embodiment, fixing rods 25 are welded to the bottoms of the rotating blocks 8, and the bottoms of the fixing rods 25 are all conical.

[0073] The specific implementation process is as follows: After the trapping cylinder 1 sinks to the designated position, when the output shaft of the AC motor 27 drives the rotating block 8 to rotate, the rotating block 8 will drive the fixed rod 25 to rotate synchronously. Since the bottoms of the fixed rods 25 are all conical, the bottoms of the fixed rods 25 will be inserted into the seabed, thereby fixing the device and preventing the device from deviating from the designated position due to the impact of seawater.

[0074] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
