Description

Technical Field

[0001] The utility model belongs to the technical field of fish breeding, and in particular relates to a rapid fish gathering device used in a breeding cabin of a breeding ship. Background Art

[0002] As the deep sea waters are far away from the land, the marine resources are richer than those in the offshore areas. With the development of capture fisheries, new space needs to be opened up for the future development of fisheries. Therefore, all countries are heading to the deep sea and the ocean. As the most advanced mobile aquaculture control platform, aquaculture vessels have emerged in some advanced aquaculture countries in recent years. Fish are kept in closed aquaculture vessels to facilitate long-term and stable harvests;

[0003] Since there are often multiple large breeding cabins in aquaculture vessels, different species of fish are cultured in different breeding cabins. In order to improve the acquisition efficiency and realize full-cycle breeding, it is necessary to capture the fish in the breeding cabin as quickly as possible when the fish mature. The capture in the breeding cabin is usually carried out by automated equipment, but the internal space of the breeding cabin is usually large. In order to improve the capture efficiency, it is best to gather the fish together before capturing. Currently, most common fish gathering devices utilize the phototaxis of fish. Since the internal space of the breeding cabin is large, the most commonly used equipment is the searchlight. However, there are often many kinds of fish in aquaculture vessels, and different fish have different perceptions of the same light. The searchlight can only adjust the color temperature at most, but it is difficult to automatically change the color.

[0004] To this end, we proposed a rapid fish gathering device for aquaculture cabins of aquaculture vessels to solve the above problems. Summary of the invention

[0008] The utility model further defines the technical solution:

[0009] Preferably, the limiting mechanism includes a driving wheel, a driven wheel, a reciprocating screw, a moving block, a curved rod and a magnetic block. The driving wheel is fixedly mounted on the side wall of the servo motor output end, and a vertical plate is fixedly mounted on the top wall of the expansion plate. One end of the reciprocating screw is fixedly mounted on the side wall of the vertical plate facing the center disk, and the other end is fixedly connected to the side wall of the driven wheel.

The curved rod is "L"-shaped, and one end of the curved rod is fixedly connected to the bottom wall of the moving block, and the other end side wall is fixedly connected to the side wall of the magnetic block. The metal claw is made of magnetic metal, and the magnetic block is adsorbed on one of the side walls of the metal claws.

[0010] Preferably, a positioning plate is fixedly connected to the bottom of the curved rod, a limiting groove is provided on the top wall of the extension plate, and the positioning plate is slidably connected to the inner wall of the limiting groove at one end away from the curved rod.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] like Figure 1-3 As shown, a rapid fish gathering device for aquaculture cabins of aquaculture vessels comprises a searchlight 1 and a servo motor 2. An expansion board 3 is installed on the side wall of the searchlight 1. The servo motor 2 is installed on the top of the expansion board 3. A plurality of metal claws 4 are fixedly installed on the output end of the servo motor 2. The metal claws 4 are "L" shaped. The short sides of the metal claws 4 are fixedly connected to the side walls of the center disk 5. The center disk 5 is fixedly installed together at one end of the plurality of metal claws 4 away from the servo motor 2.

[0021] A number of circular frames 6 are fixedly installed on the side wall of the center plate 5. The circular frames 6 are set because the searchlight 1 is cylindrical. If the searchlight 1 is square, the circular frames 6 also need to be set to be square, and the diameter of the circular frames 6 should be slightly larger than the diameter of the searchlight 1. The number of metal claws 4 is the same as the number of circular frames 6, and the position of each metal claw 4 corresponds to the position of a circular frame 6. A color-transmitting card 7 is fixedly installed inside each circular frame 6. The color of each color-transmitting card 7 is different. The color-transmitting card 7 is made of transparent material to facilitate the light of the searchlight 1 to pass through. The diameter of the color-transmitting card 7 is also larger than the diameter of the searchlight 1 to ensure that there is no light leakage. One of the color-transmitting cards 7 is located directly in front of the searchlight 1.

[0022] A limiting mechanism for fixing the position of the center disk 5 is also installed on the expansion plate 3, and the limiting mechanism includes a driving wheel 8, a driven wheel 9, a reciprocating screw rod 10, a moving block 11, a curved rod 12 and a magnetic block 13. The driving wheel 8 is fixedly installed on the side wall of the output end of the servo motor 2, and a vertical plate 14 is fixedly installed on the top wall of the expansion plate 3. One end of the reciprocating screw rod 10 is fixedly installed on the side wall of the vertical plate 14 facing the center disk 5, and the other end is fixedly connected to the side wall of the driven wheel 9. A support plate 17 is fixedly installed on the side wall of the searchlight 1. The support plate 17 is inclined. The inclined support plate 17 will not affect the mutual adsorption of the curved rod 12 and the metal claw 4. The support plate 17 is rotatably connected to the side wall of the driven wheel 9 at one end away from the searchlight 1.

[0023] The driving wheel 8 is meshed with the driven wheel 9, the moving block 11 is threadedly connected to the reciprocating screw 10, the curved rod 12 is "L"-shaped, and a positioning plate 15 is fixedly connected to the bottom of the curved rod 12. A limiting groove 16 is provided on the top wall of the extension plate 3, and the limiting groove 16 is open at one end facing the center disk 5, so that it is convenient for the positioning plate 15 to follow the curved rod 12 to move toward the metal claw 4 in a square shape. The end of the positioning plate 15 away from the curved rod 12 is slidably connected to the inner wall of the limiting groove 16. When the servo motor 2 rotates, causing one metal claw 4 to replace the position of another metal claw 4, the reciprocating screw 10 will just drive the moving block 11 to perform a reciprocating motion.

[0024] One end of the curved rod 12 is fixedly connected to the bottom wall of the moving block 11, and the other end side wall is fixedly connected to the side wall of the magnetic block 13. The metal claw 4 is made of magnetic metal, and the magnetic block 13 is adsorbed on one of the side walls of the metal claws 4. When the magnetic block 13 and the metal claw 4 are adsorbed together, the direction of the magnetic force is perpendicular to the metal claw 4, and the direction when moving the magnetic block 13 is different from the direction of the magnetic force. Therefore, the magnetic block 13 and the curved rod 12 can be smoothly separated from the metal claw 4.

[0025] The working principle is as follows: when the color of the light beam emitted by the searchlight 1 needs to be changed, the servo motor 2 is started, and the operation of the servo motor 2 drives a plurality of metal claws 4 to rotate, and the metal claws 4 in turn drive the center disk 5 and the circular frame 6 to rotate together. Since there are gaps between the plurality of metal claws 4, the rotating metal claws 4 will directly separate from the magnetic block 13;

[0026] At the same time, the rotation of the output end of the servo motor 2 will also drive the driving wheel 8 to rotate, and the driven wheel 9 meshing with the driving wheel 8 will drive the reciprocating screw 10 to rotate, thereby causing the moving block 11 to drive the curved rod 12 to move, and the curved rod 12 will drive the magnetic block 13 to leave the range of the metal claw 4, thereby facilitating the passage of the metal claw 4. When the new metal claw 4 rotates to the specified position, the new transparent card 7 moves just in front of the searchlight 1, and the curved rod 12 leads the magnetic block 13 to move to the original position, and is adsorbed together with the new metal claw 4, thereby fixing the position of the transparent card 7.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
