Description

Technical Field

[0001] The invention belongs to the technical field of fish behavior monitoring, and in particular relates to a biological investigation fish behavior monitoring device. Background Art

[0002] With the continuous development of marine fish farming, accurate information on fish behavior, changes in aquaculture water quality, and aquaculture density is a necessary condition for ensuring high quality and high yield. At present, various behavioral information of fish in the aquaculture process is mainly obtained through fish health monitoring devices. By placing the fish behavior monitoring device deep underwater and collecting images, it is ensured that important information for observing fish behavior is collected efficiently and accurately.

[0003] The visual monitoring devices of the prior art are easily affected by lighting factors when monitoring fish behavior. The lighting conditions will affect the quality of the images captured by the camera. For example, the light is relatively strong during the day, and direct exposure to the camera will cause the lens to be overexposed; insufficient light at night can easily make it difficult for the camera to capture the movement of fish. Secondly, since the sea surface temperature is higher than during the day, the air pressure is lower. This pressure difference causes the wind to blow from the land to the ocean, increasing the wind force on the sea surface, resulting in larger winds and waves at night. Larger winds and waves can easily cause the camera to shake, thereby affecting the accuracy of the behavior analysis and causing errors in the monitoring results. In order to ensure the lighting conditions during the day and at night, reduce the shaking of the camera caused by wind and waves, and ensure that the camera can normally capture fish behavior information, the present invention provides a biological survey fish behavior monitoring device. Summary of the invention

[0004] The purpose of the present invention is to provide a biological investigation fish behavior monitoring device to solve the technical problems in the prior art in view of the shortcomings of the prior art.

[0005] The object of the present invention can be achieved by the following technical scheme: a biological investigation fish behavior monitoring device, comprising a floating ring and a floating plate mounted thereon, a focusing assembly mounted on the floating plate, the floating ring is connected to a connecting column through a connecting rod, a solar light source is mounted on one end of the connecting column, and a camera capture assembly and a draft assembly are mounted on the other end of the connecting column; The focusing assembly includes a flexible focusing plate and a traction rope, a support rod is installed on the floating plate, the support rod is rotatably connected to the flexible focusing plate, a traction rope is installed on one end of the flexible focusing plate away from the connecting column, and the traction rope is connected to the camera capture assembly; The draft component comprises a centrifugal pump and a water storage bag, wherein a water inlet is installed on the water storage bag; the centrifugal pump draws seawater into the water inlet.

[0006] As a further optimization or improvement of this solution, the focusing assembly also includes a support shaft, a limit plate is installed at the bottom of the solar light source, the support rod is connected to the middle part of the flexible focusing plate through a reset shaft, and the flexible focusing plate is connected to the traction rope through a rotating shaft; when the traction rope pulls the flexible focusing plate to rotate, the support shaft abuts against the limit plate.

[0007] As a further optimization or improvement of the present solution, the video capture assembly includes a protective cover and a camera, and the camera is installed inside the protective cover.

[0008] As a further optimization or improvement of this solution, a flushing assembly is installed in the connecting column, and the flushing assembly includes a piston cavity and a one-way open piston head. The connecting column is provided with a piston cavity, and the piston head is slidably installed in the piston cavity. The piston head is connected to the top of the camera through a pull rod, and the bottom of the piston cavity is connected to a bellows, and a pressure head aimed at the camera lens is installed on the bellows.

[0009] As a further optimization or improvement of this solution, the flushing assembly also includes a pull block, which is slidably installed in the piston head and blocks the piston head. The pull block is connected to the pull rod, and a push plate is installed on the pull rod. The push plate abuts the bottom of the piston head, and a vent is opened at the top of the piston chamber.

[0010] As a further optimization or improvement of the present solution, the draft component further includes a mesh plate, which separates the centrifugal pump and the water storage bag.

[0011] As a further optimization or improvement of the present solution, the focusing assembly further includes a steering wheel, and the traction rope passes through the steering wheel and is connected to the protective cover.

[0012] Beneficial effects of the present invention: (1) During the day, the flexible concentrator is in a V-shape, which can shield the camera capture component from light and prevent the camera capture component lens from overexposure. At the same time, the flexible concentrator will concentrate light on the solar light source to improve the light energy utilization rate of the solar light source. At night, seawater is pumped into the water storage bag through a centrifugal pump to increase the water intake of the camera capture component and improve the stability of the camera capture component. The camera capture component drives the flexible concentrator to rotate to an inverted V shape, so that it can concentrate the light of the solar light source and penetrate the water surface to illuminate the area near the camera capture component, so that the camera capture component can accurately capture and record the movement of fish.

[0013] (2) At night, the present invention uses a centrifugal pump to pump seawater into the water storage bag, thereby increasing the water draft of the camera capture assembly and changing the center of gravity of the camera capture assembly. As the center of gravity of the camera capture assembly changes, the camera capture assembly will sink. At this time, the protective cover drives the pull rod to slide downward along the piston cavity. As the protective cover drives the pull rod to slide downward along the piston cavity, the pull block on the pull rod drives the piston head to compress the air in the piston cavity. When the air is compressed to a certain pressure, it is discharged from the pressure head. The air discharged from the pressure head will drive the water flow disturbance near the camera lens, thereby achieving the purpose of cleaning the camera lens and ensuring that the camera can accurately capture fish behavior at night.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 8 A biological investigation fish behavior monitoring device comprises a floating ring 1 and a floating plate 2 mounted thereon, a focusing component 6 is mounted on the floating plate 2, the floating ring 1 is connected to a connecting column 5 through a connecting rod 3, a solar light source 7 is mounted on one end of the connecting column 5, and a camera capture component 8 and a draft component 9 are mounted on the other end of the connecting column 5; The light focusing assembly 6 includes a flexible light focusing plate 601 and a traction rope 604. A support rod 606 is installed on the floating plate 2. The support rod 606 is rotatably connected to the flexible light focusing plate 601. A traction rope 604 is installed at one end of the flexible light focusing plate 601 away from the connecting column 5. The traction rope 604 is connected to the camera capture assembly 8. The draft component 9 includes a centrifugal pump 904 and a water storage bag 901 . A water inlet 902 is installed on the water storage bag 901 . The centrifugal pump 904 pumps seawater into the water inlet 902 .

[0026] It should be noted that when in use, the fish behavior monitoring device is placed on the water surface, at which time the camera capture component 8 and the draft component 9 are located underwater, the float 1 is suspended on the water surface, and the solar light source 7 is located above the water. Figure 1 During the day, the flexible concentrator plate 601 is in a V-shape as a whole. At this time, the flexible concentrator plate 601 can shield the camera capture component 8 from light, thereby preventing the camera capture component 8 from being overexposed due to direct light. At the same time, the flexible concentrator plate 601 will concentrate light on the solar light source 7, thereby increasing the light intensity of the solar light source 7 and improving the light energy utilization rate of the solar light source 7. At night, the centrifugal pump 904 is used to pump seawater into the water storage bag 901, which increases the water intake of the camera capture assembly 8, changes the center of gravity of the camera capture assembly 8, and improves the stability of the camera capture assembly 8. As the center of gravity of the camera capture assembly 8 changes, the camera capture assembly 8 sinks, and the protective cover 801 drives the pull rod 402 to slide downward along the piston chamber 401. During this process, the camera capture component 8 pulls the traction rope 604, and drives the flexible focusing plate 601 to rotate through the traction rope 604. As the flexible focusing plate 601 rotates, the support shaft 607 on the flexible focusing plate 601 stops when it abuts against the limit plate 10. At this time, the flexible focusing plate 601 is in an inverted V shape as a whole, and the light of the solar light source 7 is gathered through the flexible focusing plate 601, so that the light is transmitted underwater, thereby providing a stable light source for the camera capture component 8. As the protective cover 801 drives the pull rod 402 to slide downward along the piston chamber 401, the pull block 405 on the pull rod 402 drives the piston head 403 to compress the air in the piston chamber 401. When the air is compressed to a certain pressure, it is discharged from the pressure head 404. The air discharged from the pressure head 404 will drive the water flow disturbance near the lens of the camera 802, thereby achieving the purpose of cleaning the lens of the camera 802.

[0027] During the day, the flexible focusing plate 601 is in a V-shape, so that it can block light for the camera capture component 8 and prevent overexposure of the camera capture component 8 lens. At the same time, the flexible focusing plate 601 will focus light on the solar light source 7 to improve the light energy utilization rate of the solar light source 7; at night, seawater is pumped into the water storage bag 901 by the centrifugal pump 904 to increase the water intake of the camera capture component 8 and improve the stability of the camera capture component 8. The camera capture component 8 drives the flexible focusing plate 601 to rotate to an inverted V shape, so that it can focus the light of the solar light source 7 and penetrate the water surface to illuminate the area near the camera capture component 8, so that the camera capture component 8 can accurately capture and record the movement of fish.

[0028] See also Figure 3 The focusing assembly 6 also includes a support shaft 607, a limit plate 10 is installed at the bottom of the solar light source 7, the support rod 606 is connected to the middle part of the flexible focusing plate 601 through the reset shaft 602, and the flexible focusing plate 601 is connected to the traction rope 604 through the rotating shaft 603; when the traction rope 604 pulls the flexible focusing plate 601 to rotate, the support shaft 607 abuts against the limit plate 10.

[0029] Specifically, the focusing assembly 6 further includes a steering wheel 605 , and the traction rope 604 passes through the steering wheel 605 and is connected to the protective cover 801 .

[0030] It should be noted that the reset shaft 602 has a built-in torsion spring. When the traction rope 604 pulls the flexible focusing plate 601 to rotate, the torsion spring inside the reset shaft 602 is stretched. When the traction rope 604 withdraws from pulling the flexible focusing plate 601, the torsion spring inside the reset shaft 602 drives the flexible focusing plate 601 to reset.

[0031] See also Figure 4-Figure 7 The camera capture assembly 8 includes a protective cover 801 and a camera 802, and the camera 802 is installed inside the protective cover 801. It should be noted that the connecting rod 3 and the protective cover 801 are made of transparent plastic material, which has a certain buoyancy while reducing the blocking of the light of the solar light source 7 by the connecting rod 3 and the protective cover 801; wherein the protective cover 801 is a flexible transparent plastic, so that the protective cover 801 has a certain protective effect on the camera 802.

[0032] See also Figure 4-Figure 7A flushing assembly 4 is installed in the connecting column 5, and the flushing assembly 4 includes a piston chamber 401 and a one-way open piston head 403. The connecting column 5 is provided with a piston chamber 401, and the piston head 403 is slidably installed in the piston chamber 401. The piston head 403 is connected to the top of the camera 802 through a pull rod 402. The bottom of the piston chamber 401 is connected to a bellows 407, and a pressure head 404 aimed at the lens of the camera 802 is installed on the bellows 407.

[0033] It should be noted that the lighting and illumination range at night are far inferior to those during the day. Therefore, when night falls, in order to reduce the impact of plankton or debris particles attached to the lens of camera 802 on its accuracy, it is necessary to ensure that the lens surface of camera 802 is clean to improve the capture accuracy of camera 802.

[0034] At night, the present invention pumps seawater into the water storage bag 901 through the centrifugal pump 904, thereby increasing the water draft of the camera capture assembly 8, changing the center of gravity of the camera capture assembly 8, and improving the stability of the camera capture assembly 8. As the center of gravity of the camera capture assembly 8 changes, the camera capture assembly 8 will sink. At this time, the protective cover 801 drives the pull rod 402 to slide downward along the piston cavity 401. As the protective cover 801 drives the pull rod 402 to slide downward along the piston cavity 401, the pull block 405 on the pull rod 402 drives the piston head 403 to compress the air in the piston cavity 401. When the air is compressed to a certain pressure, it is discharged from the pressure head 404. The air discharged from the pressure head 404 will drive the water flow disturbance near the lens of the camera 802, thereby achieving the purpose of cleaning the lens of the camera 802 and ensuring that the camera 802 can accurately capture fish behavior at night.

[0035] See also Figure 5-Figure 6 The flushing assembly 4 also includes a pull block 405, which is slidably installed in the piston head 403 and blocks the piston head 403. The pull block 405 is connected to the pull rod 402, and a push plate 406 is installed on the pull rod 402. The push plate 406 abuts against the bottom of the piston head 403, and a vent 408 is opened at the top of the piston chamber 401.

[0036] It should be noted that when the camera capture component 8 draws water through the draft component 9, the camera capture component 8 sinks. At this time, the camera capture component 8 drives the pull block 405 to move downward through the pull rod 402. At this time, the pull block 405 drives the piston head 403 to move downward together, so that it compresses the air inside the piston chamber 401; when the camera capture component 8 drains water through the draft component 9, the camera capture component 8 is reset. At this time, the pull rod 402 drives the pull block 405 to move upward along the piston chamber 401, so that the pull block 405 is separated from the piston head 403. At this time, air enters the piston chamber 401 through the vent 408. As the pull block 405 moves upward, the push plate 406 drives the piston head 403 to move upward and reset synchronously.

[0037] See also Figure 8 The water draft component 9 also includes a mesh plate 903, which separates the centrifugal pump 904 and the water storage bag 901.

[0038] It should be noted that the function of the mesh plate 903 is to isolate impurities in the water from entering the centrifugal pump 904 .

[0039] The implementation principle of the present invention is: when in use, the fish behavior monitoring device is placed on the water surface, at which time the camera capture component 8 and the draft component 9 are located underwater, the float 1 is suspended on the water surface, and the solar light source 7 is located above the water. Figure 1 During the day, the flexible concentrator plate 601 is in a V-shape as a whole. At this time, the flexible concentrator plate 601 can shield the camera capture component 8 from light, thereby preventing the camera capture component 8 from being overexposed due to direct light. At the same time, the flexible concentrator plate 601 will concentrate light on the solar light source 7, thereby increasing the light intensity of the solar light source 7 and improving the light energy utilization rate of the solar light source 7. At night, seawater is pumped into the water storage bag 901 through the centrifugal pump 904 to increase the water draft of the camera capture component 8, change the center of gravity of the camera capture component 8, and improve the stability of the camera capture component 8. As the center of gravity of the camera capture component 8 changes, the camera capture component 8 will sink, and at this time the protective cover 801 drives the pull rod 402 to slide downward along the piston cavity 401; in this process, the camera capture component 8 pulls the traction rope 604, and drives the flexible focusing plate 601 to rotate through the traction rope 604. As the flexible focusing plate 601 rotates, the support shaft 607 on the flexible focusing plate 601 stops when it abuts the limit plate 10. At this time, the flexible focusing plate 601 is in an inverted V shape as a whole, and the light of the solar light source 7 is gathered through the flexible focusing plate 601, so that the light is transmitted into the water, thereby providing a stable light source for the camera capture component 8; As the protective cover 801 drives the pull rod 402 to slide downward along the piston chamber 401, the pull block 405 on the pull rod 402 drives the piston head 403 to compress the air in the piston chamber 401. When the air is compressed to a certain pressure, it is discharged from the pressure head 404. The air discharged from the pressure head 404 will drive the water flow disturbance near the lens of the camera 802, thereby achieving the purpose of cleaning the lens of the camera 802.
