Description

Technical Field

[0001] The present invention relates to the technical field of fish situation monitoring, and specifically provides a multifunctional platform for underwater light field testing of fish attracting lights. Background Technique

[0002] Fish situation monitoring is a process of observing, detecting, and analyzing the status of fish resources and the ecological environment. Its purpose is to understand information such as the species, quantity, distribution, growth status, reproduction, and the impact of the water environment on fish, providing a scientific basis for fishery management, resource protection, and maintaining ecological balance.

[0003] Light has a great impact on fish schools. In the night or in waters with relatively dim light, light may attract some fish with phototaxis. These fish may be attracted by the light to a specific area, thus increasing the fish density in that area.

[0004] However, too strong or inappropriate light may also startle fish. Strong light may make fish feel uneasy, affecting their normal behavior and habitat. This may cause fish to flee from the light area, or become more vigilant and reluctant to feed or move. Different species of fish may have different reactions to light. Some fish have strong phototaxis, while others are more sensitive or uninterested in light. In actual fishing or fishery activities, it is necessary to reasonably utilize light according to specific circumstances to achieve the best effect.

[0005] Therefore, we propose a multifunctional platform for underwater light field testing of fish attracting lights to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a multifunctional platform for underwater light field testing of fish attracting lights to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the present invention provides the following technical solution: A multifunctional platform for underwater light field testing of fish attracting lights, including a detection platform and two groups of floating air bags fixedly connected to the bottom of the detection platform. An operation opening is provided on the surface of the detection platform, and an observation board is fixedly connected to the inner wall of the operation opening;

[0008] A placement bucket is inserted into the inner cavity of the operation opening. A through opening adapted to the placement bucket is provided on the surface of the observation board. A telescopic cylinder is fixedly connected to the inner cavity of the placement bucket, and a fish attracting lamp ball is fixedly connected to the bottom end of the telescopic cylinder. The diameter of the fish attracting lamp ball is smaller than the inner diameter of the placement bucket;

[0009] Two sets of erection plates are provided on the top of the observation board. A gear roller is rotatably connected between each set of erection plates. Two sets of gear racks are fixedly connected to the surface of the placement bucket, and the gear roller is engaged with the gear rack;

[0010] A monitoring system is also provided at the exact lower end of the described detection platform. A monitoring camera is provided inside the monitoring system, and mounting brackets are provided on both sides of the monitoring system.

[0011] In a further embodiment, a brushless motor is fixedly connected to the surface of the erection plate, and the output end of the brushless motor penetrates through the surface of a set of erection plates and is fixedly connected to a gear roller.

[0012] In a further embodiment, the observation plate is composed of a combination of float glass and polycarbonate fiber. After the combination of the float glass and the polycarbonate fiber, while ensuring a certain strength, the optical performance of the observation plate is also maintained, ensuring the accuracy and clarity of observation.

[0013] In a further embodiment, two sets of placement shells are fixedly connected to the inner walls of the operation ports. Linkage rods are slidably connected to the inner cavities of the placement shells, and cleaning semi-rings are fixedly connected to the other ends of the linkage rods.

[0014] In a further embodiment, springs are provided in the inner cavities of the placement shells, and the other ends of the springs are fixedly connected to the linkage rods. The cleaning semi-rings are semi-circular arcs and fit against the outer surface of the placement barrel. The cleaning semi-rings are always in contact with the placement barrel. When the placement barrel moves up and down, the cleaning semi-rings wipe and clean the placement barrel and the gear teeth on its surface.

[0015] In a further embodiment, the head of the detection platform is designed as an inverted triangular arrow shape, and a propeller drive device for driving its displacement is provided at the tail of the detection platform. The inverted triangular arrow shape design at the head of the detection platform can reduce resistance in water, making the detection platform move more smoothly during movement, improving energy utilization efficiency and speed. The propeller drive device at the tail of the detection platform can provide flexible power output, enabling more precise control of direction and speed, and enhancing its maneuverability and controllability.

[0016] In a further embodiment, a waterproof metal shell is provided outside the monitoring system, and electric self-locking rotating shafts are installed on both sides of the shell, and the electric self-locking rotating shafts are fixedly installed on the mounting brackets.

[0017] In a further embodiment, positioning holes are provided at the lower ends of the mounting brackets, and the fixed ends of the electric self-locking rotating shafts are installed in these positioning holes. An electric extension rod is provided on the mounting brackets, and a connection block is provided at the other end of the electric extension rod, and the connection block is fixedly installed at the bottom end of the detection platform.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The detection platform floats on the water surface through a floating airbag. The inverted triangular arrow-shaped design at the head of the detection platform can reduce resistance in the water, making the detection platform move more smoothly during motion, improving energy utilization efficiency and speed. The propeller drive device at the tail of the detection platform can provide flexible power output, enabling more precise control of direction and speed, enhancing its maneuverability and controllability, and allowing it to move to different areas to test the lights.

[0020] Start the brushless motors fixedly connected to the surface of the erection plate. The two groups of brushless motors drive the two groups of gear rollers to rotate in opposite directions. The gear rollers are engaged with the gear racks fixedly connected to the surface of the placement barrel. When the gear rollers rotate, they simultaneously control the placement barrel to move up and down through the gear racks. The telescopic cylinder fixedly connected to the inner cavity of the placement barrel can be started to push the fish attracting lamp ball downward for displacement, pushing the fish attracting lamp ball to waters at different depths to test the light of the fish attracting lamp ball.

[0021] When the placement barrel moves up and down, the spring in the inner cavity of the placement shell releases elasticity, pushing the linkage rod and the cleaning semi-ring to move towards the placement barrel, keeping the cleaning semi-ring in contact with the placement barrel. When the placement barrel moves up and down, the cleaning semi-ring wipes and cleans the placement barrel and the gear rack on its surface, ensuring the overall service life.

[0022] After the monitoring system launches the fish attracting lamp ball, it will continuously monitor the fish attracting lamp ball to observe its actual effect underwater, and thus transmit the test data in a timely manner. When no test is being carried out, the monitoring system, in cooperation with the movement of the platform, observes the situation at the bottom of the water to find a suitable water area for testing to make the test effect better.

Specific implementation manner

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-5 , the present invention provides a technical solution: a multifunctional platform for underwater light field testing of fish attracting lamps, including a detection platform 1 and two groups of floating airbags 2 fixedly connected to the bottom of the detection platform 1. The detection platform 1 floats on the water surface through the floating airbags 2. The inverted triangular arrow-shaped design at the head of the detection platform 1 can reduce resistance in water, making the detection platform 1 move more smoothly during movement, improving energy utilization efficiency and speed. The propeller drive device at the tail of the detection platform 1 can provide flexible power output, enabling more precise control of direction and speed, enhancing its maneuverability and controllability, and can be moved to different areas to test the lights.

[0031] When moving to the test water area, start the brushless motors 11 fixedly connected to the surface of the erection board 8. The two groups of brushless motors 11 drive the two groups of gear rollers 9 to rotate in opposite directions. The gear rollers 9 are engaged with the gear racks 10 fixedly connected to the surface of the placement bucket 5. When the gear rollers 9 rotate, they simultaneously control the up and down displacement of the placement bucket 5 through the gear racks 10. The telescopic cylinder 6 fixedly connected to the inner cavity of the placement bucket 5 can be started to push the fish attracting lamp ball 7 downward for displacement, pushing the fish attracting lamp ball 7 to waters at different depths to test the light of the fish attracting lamp ball 7;

[0032] When the whole body moves on the water surface, the telescopic cylinder 6 can be retracted to drive the fish attracting lamp ball 7 to be received into the placement barrel 5. Then, start the brushless motor 11 to lift the placement barrel 5 through the gear roller 9, so that it is away from the water body, avoiding bumps that may damage the fish attracting lamp ball 7. When the placement barrel 5 moves up and down, the spring 15 in the inner cavity of the placement shell 12 releases its elasticity, pushing the linkage rod 13 and the cleaning semi-ring 14 to move towards the placement barrel 5, keeping the cleaning semi-ring 14 always in tight contact with the placement barrel 5. When the placement barrel 5 moves up and down, the cleaning semi-ring 14 wipes and cleans the placement barrel 5 and the gear bar 10 on its surface, ensuring the overall service life;

[0033] The observation plate 4 is composed of float glass and polycarbonate fiber. Compared with traditional glass materials, polycarbonate fiber has a lower density. Using polycarbonate fiber in combination with float glass can reduce the weight of the observation plate 4, facilitating installation and handling. Float glass has good optical transparency and flatness, capable of providing a clear visual effect. After the combination of float glass and polycarbonate fiber, while ensuring a certain strength, the optical performance of the observation plate 4 is also maintained, ensuring the accuracy and clarity of observation. The top platform of the detection platform 1 can place a sonar detector or other experimental equipment, facilitating a clearer detection of fish clearance;

[0034] Before the test, when the detection platform 1 floats on the water surface, the monitoring system 17 set at the lower end of the detection platform 1 will continuously observe the bottom of the water to find a suitable water area environment. During the observation process, the outside of the monitoring system 17 is provided with a waterproof shell, and a high-definition monitoring camera 21 is installed inside to monitor the bottom of the water. At the same time, an electric self-locking rotating shaft 22 is also provided on both sides of the monitoring system 17. The electric self-locking rotating shaft 22 is installed in the positioning hole 18 at the mounting frame 16. During monitoring, the monitoring system 17 rotates around the positioning hole 18 with the electric self-locking rotating shaft 22 as the origin to adjust the monitoring angle;

[0035] During the test, through the electric extension rod 19 set in the mounting frame 16, the mounting frame 16 is extended on the connecting block 20. In cooperation with the angle adjustment of the monitoring system 17, it can accurately detect the fish attracting lamp ball 7 when it descends to different depths.

[0036] Working principle: The detection platform 1 floats on the water surface through the floating airbag 2. The inverted triangular arrow-shaped design at the head of the detection platform 1 can reduce resistance in the water, making the detection platform 1 move more smoothly during movement, improving energy utilization efficiency and speed. The propeller drive device at the tail of the detection platform 1 can provide flexible power output, enabling more precise control of direction and speed, enhancing its maneuverability and controllability, and it can move to different areas to test the lights. When it moves to the test water area, start the brushless motor 11 fixedly connected to the surface of the erection plate 8. The two brushless motors 11 drive the two gear rollers 9 to rotate in opposite directions. The gear rollers 9 are engaged with the gear racks 10 fixedly connected to the surface of the placement barrel 5. When the gear rollers 9 rotate, they simultaneously control the placement barrel 5 to move up and down through the gear racks 10. The telescopic cylinder 6 fixedly connected to the inner cavity of the placement barrel 5 can be started to push the fish attracting lamp ball 7 downward for displacement, pushing the fish attracting lamp ball 7 to waters at different depths to test the light of the fish attracting lamp ball 7. When the whole is moving on the water surface, the telescopic cylinder 6 can be contracted to drive the fish attracting lamp ball 7 to be received into the placement barrel 5, and then start the brushless motor 11 to raise the placement barrel 5 through the gear rollers 9 to lift it out of the water body to avoid damage to the fish attracting lamp ball 7 caused by collision. When the placement barrel 5 is moving up and down, the spring 15 in the inner cavity of the placement shell 12 releases its elasticity, pushing the linkage rod 13 and the cleaning semi-ring 14 to move towards the placement barrel 5, keeping the cleaning semi-ring 14 always in contact with the placement barrel 5. When the placement barrel 5 is moving up and down, the cleaning semi-ring 14 wipes and cleans the placement barrel 5 and the gear rack 10 on its surface to ensure the overall service life. The observation plate 4 is composed of float glass and polycarbonate fiber. Compared with traditional glass materials, polycarbonate fiber has a lower density. Using the combination of polycarbonate fiber and float glass can reduce the weight of the observation plate 4, facilitating installation and handling. Float glass has good optical transparency and flatness, capable of providing a clear visual effect. After the combination of float glass and polycarbonate fiber, while ensuring a certain strength, the optical performance of the observation plate 4 is also maintained, ensuring the accuracy and clarity of observation. The top platform of the detection platform 1 can place a sonar detector or other experimental equipment, facilitating a clearer detection of the fish situation, and solving the problem that too strong or inappropriate lights may also disturb the fish. Strong lights may make the fish feel uneasy, affecting their normal behavior and habitat. This may cause the fish to flee the lighted area, or become more vigilant, reluctant to feed or move. Different species of fish may have different reactions to lights. Some fish have strong phototaxis, while others are more sensitive or uninterested in lights.In actual fishing or fishing activities, it is necessary to reasonably utilize lights according to specific circumstances to achieve the best results. Before the test, when the detection platform 1 floats on the water surface, the monitoring system 17 installed at the lower end of the detection platform 1 will continuously observe the bottom of the water to find a suitable water environment. During the observation process, the outside of the monitoring system 17 is provided with a waterproof shell, and a high-definition monitoring camera 21 is installed inside to monitor the bottom of the water. At the same time, an electric self-locking rotating shaft 22 is provided on both sides of the monitoring system 17. The electric self-locking rotating shaft 22 is installed in the positioning hole 18 at the mounting frame 16. During monitoring, the monitoring system 17 rotates around the positioning hole 18 with the electric self-locking rotating shaft 22 as the origin to adjust the monitoring angle; during the test, through the electric extension rod 19 installed in the mounting frame 16, the mounting frame 16 is extended on the connecting block 20. In cooperation with the angle adjustment of the monitoring system 17, when the fish attracting lamp ball 7 descends to different depths, it can be accurately detected, and the data is uploaded and saved in real time; the monitoring system 17 is a prior art. When in use, a microprocessor is provided in the observation board 4 to connect the monitoring system 17, and at the same time, the influence is transmitted to the monitoring room, where there is an imaging sensor, that is, the monitoring camera 21, for the most intuitive monitoring of the bottom of the water situation. A network sensor is also provided for transmission through network signals, and according to the different detection waters, it cooperates with other detection platforms 1 during detection, so as to form a two-dimensional or three-dimensional underwater stereo detection network.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
