Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fishing, in particular to a seawater fish ecological light trapping device. BACKGROUND

[0002] In the existing marine fishery fishing, the light trapping technology is widely used because of its relatively simple operation and less impact on ecology. Generally, trawl operation or net cage composed of single netting is used as the main body of trapping. The net cage has a single interception structure. In addition, the light component for trapping is mostly a single lamp body, which is easy to be displaced or accumulated due to water flow impact, and cannot continuously and uniformly play the role of attraction, making it difficult to effectively gather fish. In this regard, the prior art has proposed corresponding technical means. For example, the existing technology HK40050426A1 provides a fish gathering lamp device installed on a fishing boat and used for gathering fish by irradiating light, which comprises: a light source part having at least one LED; a reflector configured to be opposite to the light source part on the optical axis of the light source part at the top, and to reflect the light from the light source part to the surrounding direction away from the optical axis. The reflecting surface of the reflector has a side surface shape of a substantially conical or substantially conical frustum shape. Another example is the existing technology TWM613229U, which provides a satellite or radio intelligent fish gathering device, which is composed of an artificial fishing reef, a fish gathering device, a satellite electric buoy and an LED fish gathering lamp. The LED fish gathering communication is arranged in the artificial fishing reef under the sea, and the LED fish gathering lamp is electrically connected with the satellite electric buoy through a signal control line. The satellite of the satellite electric buoy forms a radio communication module to control the opening and closing of the LED fish gathering lamp, and can also control the light source direction, wavelength and color temperature of the LED fish gathering lamp. In this way, the user can directly control the light source of the LED fish gathering lamp from a remote place, and adjust the light to turn on and off instantaneously with the vibration of the fish school, so as to increase the probability of attracting a large number of fish school, thereby improving the catch. However, the existing light trapping device still has room for improvement in realizing large-scale gathering effect and improving trapping effect. SUMMARY

[0003] The present application aims to provide a seawater fish ecological light trapping device, which solves the problems of high risk of escape of catch caused by the single interception structure of the existing net cage and the displacement or accumulation of the light component caused by water flow impact, which cannot continuously and uniformly play the role of attraction.

[0004] To solve the above technical problems, the present application specifically provides the following technical solutions: the seawater fish ecological light trapping device comprises a trapping box, the trapping box has a net cage with a box structure, the net cage is provided with a net cover on each surface, the net cover on at least one side of the net cage is provided with a second opening, and the net cage is internally provided with a light assembly with a lamp body; the trapping box is connected with a buoyancy assembly arranged on the water surface through an anchor rope. The net cage is provided with the net cover on each surface, and the second opening on the side reduces the escape obstacles while providing a smooth access channel for the seawater fish. The light assembly with the lamp body internally arranged in the net cage can attract the fish school to gather around the net cage at a close distance, thereby improving the trapping pertinence. The trapping box is connected with the buoyancy assembly arranged on the water surface through the anchor rope, so that the position of the device in the water can be stabilized, the trapping area can be prevented from changing due to the water flow drift, and the cooperation between the light and the net cage can be ensured to be continuous and effective.

[0005] According to an embodiment of the present application, the upper part of the net cage is detachably connected with a box cover, and the box cover is connected with the buoyancy assembly through an anchor rope. The box cover is through-penetrated from top to bottom and is provided with a net cover, so that multiple layers of the net cover are formed on the upper part of the net cage. The net cover on the upper part of the net cage is detachable, so that the fish caught in the net cage can be quickly taken out after subsequent salvage by detaching the box cover and the net cover on the upper part of the net cage, and the operation process on the ship after catching is simplified. Furthermore, the through-penetrated net cover design forms multiple layers of interception with the net cover of the net cage itself, enhances the blocking effect on the entering fish catch, and reduces the escape risk. At the same time, the box cover is connected with the buoyancy assembly through the anchor rope, so as to assist in fixing the position of the upper part of the net cage, avoid the deviation of the net cage due to the water flow impact, and ensure the continuous and stable cooperation between the light assembly and the net cage for the trapping effect.

[0006] According to an embodiment of the present application, the light assembly comprises a connecting rope body connected with the anchor rope, the connecting rope body is connected with a light substrate at the bottom, and the light substrate is provided with a lamp body connected therewith. The light assembly is stably suspended in the net cage by connecting the connecting rope body with the anchor rope, so as to avoid the position deviation of the lamp body due to the water flow impact, ensure that the illumination range is concentrated in the net cage, and improve the directional attraction effect on the fish school. The light substrate provides a stable mounting carrier for the lamp body, ensures the relative position between the lamp body and the net cage to be fixed, makes the light continuously act on the periphery and the interior of the net cage, and enhances the attraction strength on the fish school.

[0007] According to an embodiment of the present application, at least two annular plates are arranged around the lamp body, the annular plates and the light substrate are both provided with assembly slots, and the first partition plate is connected between the annular plates and the light substrate. The waterproof controller and the battery are arranged below the light substrate. The circular plate of the light substrate is provided with assembly slots around the side surface, and the first partition plate is connected to the light substrate and the annular plate in a plug-in manner. The present application forms a multi-layer surrounding structure by surrounding the lamp body with at least two annular plates and cooperating with the first partition plate to refract and guide the light emitted by the lamp body, optimizes the illumination range, realizes directional attraction to the fish group, and designs the assembly slots of the annular plate and the light substrate to quickly connect the first partition plate in a plug-in manner, facilitating assembly, disassembly and maintenance, and flexibly adjusting the structure to adapt to different trapping scenes. The light substrate is a circular plate and is provided with assembly slots on the side surface, ensuring that the first partition plate is evenly distributed, and the light diffusion is more balanced. The waterproof controller and the battery below the light substrate provide stable power supply for the lamp body and ensure the safety of underwater work.

[0008] According to an embodiment of the present application, the inner bottom of the net cage is provided with a bait assembly, the bait assembly comprises a mounting bracket which is detachably connected to one side of the net cage, the mounting bracket is provided with a horizontally arranged sliding rail on the side surface, the sliding rail is provided with a sliding rod which can slide relative to the sliding rail, the sliding rod is sequentially provided with a first placement plate and a second placement plate, and the upper end of the sliding rod is connected to the annular plate at the bottom of the light assembly through an anchor rope. The mounting bracket is detachably connected to the net cage, facilitating quick assembly, disassembly and maintenance. The net cage is provided with a horizontally arranged sliding rail inside, cooperating with the slidable sliding rod, and the upper end of the sliding rod is connected to the annular plate of the light assembly through an anchor rope, so that the bait assembly can be adjusted synchronously with the position of the light assembly, improving the effect of light and bait attraction, thereby enhancing the attraction effect on the fish group. In addition, the first placement plate and the second placement plate sequentially arranged on the sliding rod form a multi-layer bait placement structure, which expands the bait distribution range, avoids concentrated accumulation, and improves the continuity and coverage of the attraction.

[0009] According to an embodiment of the present application, the first placement plate and the second placement plate are arranged around the sliding rod, and the surfaces of the first placement plate and the second placement plate are provided with protruding rod body parts connected with the sliding rod, and the surfaces of the first placement plate and the second placement plate are provided with net clothes. The bait can be placed in the space between the protruding rod body parts of the first placement plate and the second placement plate, and then the net clothes can be placed above the bait to avoid large displacement of the bait. The protruding rod body parts can divide the first placement plate and the second placement plate into multiple spaces, so as to disperse the bait. The first placement plate and the second placement plate are arranged around the sliding rod to form a multi-layer distribution structure, so as to expand the coverage range of the bait in the net cage and enhance the attraction to fish groups in different water layers. Furthermore, the protruding rod body parts on the surfaces of the first placement plate and the second placement plate divide them into multiple independent spaces to realize the dispersed placement of the bait, avoid the local attraction decay caused by the concentrated accumulation of the bait, prolong the continuous attraction time, and effectively block the water flow impact through the surface net clothes covering to prevent the bait from producing large displacement and ensure the stable position of the bait in each space.

[0010] According to an embodiment of the present application, the buoyancy assembly comprises a first float connected with an anchor rope, and the side surface of the first float is provided with an annular chute, and the chute is provided with a connecting base plate capable of sliding relative to the chute. The connecting base plates on each buoyancy assembly can be connected through the anchor rope. The first float provides stable buoyancy through the anchor rope to ensure the suspension stability of the trapping cage on the water surface. The sliding cooperation of the annular chute on the side surface of the first float and the connecting base plate enables the connecting base plate to be flexibly adjusted in position to facilitate the adaptation to the layout requirements of different sea areas. The connecting base plates of each buoyancy assembly are connected through the anchor rope to realize the interval arrangement of multiple trapping cages, utilize the cooperation of the light assemblies of the trapping cages to realize the attraction effect, expand the fish gathering range, reduce the dispersion of fish groups, and thus improve the catch in a unit sea area.

[0011] According to an embodiment of the present application, the side surface of the first float is provided with an arc-shaped first connecting rod, the two ends of the first connecting rod are provided with second floats, and the first connecting rod is connected with the connecting base plate. When the connecting base plate slides relative to the chute of the first float, the first connecting rod and the second floats can be driven to rotate around the first float. The first connecting rod is connected with the connecting base plate, and when the connecting base plate slides along the chute of the first float, the first connecting rod and the second floats are further driven to rotate around the first float, so that the second floats can be adaptively adjusted in position along the water flow direction, the impact of the water flow on the overall structure is reduced, and the anti-overturning capability of the equipment in water is enhanced. At the same time, the second floats and the first float form multi-point buoyancy support to improve the load stability of the buoyancy assembly and ensure the stability of the suspension position of the trapping cage.

[0012] Specifically, the arc-shaped first connecting rod can reduce the frontal impact area with the water flow when rotating with the connecting base plate, reduce the water flow resistance, make the position adjustment of the second floating body more smooth, avoid the structure from being stuck due to turbulent water flow, and at the same time, when the water flow is rapid, the second floating body is offset to the rear of the water flow side by rotating, forming a dispersed buoyancy support, avoiding the single-point buoyancy concentrated stress, and when the water flow is gentle, it can be reset to form a symmetrical support, ensuring that the buoyancy distribution is always balanced. In addition, when the adjacent trapping box has a large positional deviation due to the water flow, the connecting base plate drives the first connecting rod to rotate, and the position of the second floating body is adjusted to offset part of the impact force, reducing the pulling stress of the anchor rope, and indirectly ensuring the relative position stability of the light assembly and the bait assembly of the trapping box.

[0013] According to an embodiment of the present application, the bottom side of the net cage is provided with an auxiliary net plate inclined thereto, and the auxiliary net plate is a rectangular frame structure provided with a net cover. The inclination angle of the auxiliary net plate can guide the fish group close to the bottom of the net cage to the second opening on the side of the net cage, thereby expanding the effective trapping range and avoiding the fish group from lingering at the bottom to escape. In addition, the rectangular frame structure ensures the tension of the net cover and enhances the adaptability to the water flow.

[0014] According to an embodiment of the present application, the bottom of the trapping box is provided with a detachable extension rod. The bottom of the frame structure of the trapping box is inserted into the extension rod, the frame structure of the trapping box has an insertion hole, the bottom of the extension rod is provided with a roller, and the extension rod is detachably connected through the insertion hole at the bottom of the frame of the trapping box. The extension rod can be removed during underwater operation, thereby avoiding affecting the balance of the trapping box in water and the trapping effect. After being salvaged and landed, the bottom roller of the inserted extension rod can convert the sliding friction between the trapping box and the deck of the ship into rolling friction, thereby greatly reducing the dragging resistance and saving labor costs.

[0015] Compared with the prior art, the seawater fish ecological light trapping device of the present application has the advantages of improving the interception stability and trapping range of the net cage, enhancing the impact resistance and light uniformity of the light assembly, improving the cooperation and attraction effect of the light and the bait, facilitating the large-scale interval arrangement of multiple devices to expand the fish aggregation range, and improving the convenience of device operation.

At the same time, the second float 15 and the first float 11 form multi-point buoyancy support, which improves the load stability of the buoyancy assembly 10 and ensures the stability of the suspension position of the trap box 30.

[0040] Specifically, the arc-shaped first connecting rod 13 can reduce the frontal impact area with the water flow when rotating with the connecting base plate 12, reduce the water flow resistance, make the position adjustment of the second float 15 more smooth, avoid the structure from being stuck due to turbulent water flow, and at the same time, when the water flow is rapid, the second float 15 is offset to the rear side of the water flow by rotating, forming a dispersed buoyancy support, avoiding single-point buoyancy stress concentration, and when the water flow is gentle, the second float 15 can be reset to form a symmetrical support, ensuring that the buoyancy distribution is always balanced. In addition, when the adjacent trap boxes 30 have a large positional deviation due to the water flow, the connecting base plate 12 drives the first connecting rod 13 to rotate, and the positional fine adjustment of the second float 15 offsets part of the impact force, reduces the pulling stress of the anchor rope 20, and indirectly ensures the relative position stability of the light assembly 60 and the bait assembly 50 of the trap box 30.

[0043] Embodiment 2:

[0044] In this embodiment, based on the embodiment 1, referring to the accompanying drawings, Figures 4-7 The second opening 35 on the net cage 31 is provided with a cover 32, and the cover 32 is provided with a trapping assembly 40. The trapping assembly 40 has a mounting plate 41, and the side of the mounting plate 41 is provided with a connecting block connected with the cover 32. The connecting block and the cover 32 are connected by a threaded fastener, which is convenient for disassembly. The surface of the mounting plate 41 is provided with a strip-shaped first opening 42.

[0045] A first pipe body 43 is arranged below the mounting plate 41, and the mounting plate 41 covers the first pipe body 43 on both sides. The mounting plate 41 and the first pipe body 43 are both provided with mounting blocks 44 for assembly. The pipe opening of the first pipe body 43 corresponds to the second opening 35.

[0046] One end of the first pipe body 43 is arranged in the net cage 31, and a cover plate 45 is rotatably connected to the edge of the port in the net cage 31. The cover plate 45 can open the pipe opening of the first pipe body 43 under the action of an external force. After the pushing force disappears, the cover plate 45 automatically falls down, thereby avoiding the biological sheath in the net cage 31.

[0047] The mounting plate 41 is connected with the threaded fastener box cover 32 through the connecting block, which is quickly disassembled, and is convenient for maintenance and cleaning; the surface strip-shaped first opening 42 can assist in guiding the fish flow direction and improving the entering efficiency. The mounting plate 41 covers the first pipe body 43, and cooperates with the mounting block 44 to form a stable connection, so that the first pipe body 43 is accurately connected with the second opening 35 of the net cage 31, and a smooth entering channel is provided for the fish. The cover plate 45 inside the first pipe body 43 is designed to be opened in one direction, and is opened only when an external force pushes it to enter, and is automatically closed after the pushing force disappears, which effectively prevents the fish in the net cage 31 from escaping, and greatly reduces the escape rate.

[0048] The extension direction of the strip-shaped first opening 42 on the surface of the mounting plate 41 can be consistent with the direction of the pipe opening of the first pipe body 43. When the fish is attracted to the box cover 32 by the lamp body 64 of the light assembly 60 and the bait of the bait assembly 50, it will swim along the surface of the mounting plate 41, and the linear structure of the strip-shaped opening can form visual guidance, so that the fish naturally gathers along the strip-shaped direction, reducing the dispersion of irregular swimming. At the same time, the strip-shaped opening can reduce the obstruction of the mounting plate 41 to the water flow. The water flow can smoothly flow through the strip-shaped opening, forming a local water flow trend along the strip-shaped direction, and the fish usually has the habit of swimming with the water flow, and will follow the water flow direction to approach the pipe opening of the first pipe body 43, and then enter the net cage 31 through the first pipe body 43 corresponding to the second opening 35.
