Description

Technical Field

[0001] This utility model belongs to the field of aquaculture technology, specifically relating to a replaceable fishing device for aquaculture. Background Technology

[0002] Aquaculture refers to the production activities of breeding, cultivating, and harvesting aquatic animals and plants under human control. Traditional fishing operations mainly rely on the experience and skill level of fishermen, requiring a large amount of manpower. Automated fishing equipment, on the other hand, can reduce the need for manual operation and lower labor costs. This not only reduces the labor intensity of fishermen but also improves the economic efficiency of the fishing industry.

[0003] Chinese utility model patent CN217012391U discloses a replaceable harvesting device for aquaculture, relating to the field of aquaculture technology. This utility model includes an aquaculture pond, with a fixed column fixedly installed on the upper surface of the pond. A cylinder is fixedly installed on the upper surface of the fixed column, and a lifting plate is fixedly connected to the output end of the cylinder. A sliding groove is formed on the side wall of the fixed column, and one end of the lifting plate extends out of the sliding groove and is slidably connected thereto. A moving column is slidably connected to the lower surface of the lifting plate via a moving mechanism. An installation block is fixedly connected to the lower surface of the moving column via a snap-fit ​​mechanism. A waterproof motor is fixedly installed on the side wall of the installation block, and a rotating shaft is fixedly connected to the output end of the waterproof motor via a coupling.

[0004] While the above technical solution facilitates the automatic movement of the fishing net during fishing, improving the fishing efficiency of the device, it lacks the function of disassembling the mounting plate. As we know, the fishing net is the most easily worn part of the fishing device. If it cannot be disassembled, the mounting block, waterproof motor, and mounting rod may all need to be replaced due to damage to the fishing net, rather than just replacing the fishing net itself. This leads to a waste of resources from undamaged parts and increases maintenance costs. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 As shown, this utility model embodiment provides a replaceable harvesting device for aquaculture, specifically including an aquaculture pond 1. A connecting assembly is provided on one side of the top of the aquaculture pond 1. The connecting assembly includes a fixed column 201 fixedly installed on one side of the top of the aquaculture pond 1. A cylinder 202 is fixedly installed on the top of the fixed column 201. A lifting plate 203 is fixedly installed at the telescopic end of the cylinder 202. The lifting plate 203 is slidably connected to the fixed column 201. A movable column 204 is provided at the bottom of the lifting plate 203. An installation block 205 is provided at the bottom of the movable column 204. A rotating shaft 206 is movably installed inside the installation block 205. An installation rod 207 is fixedly installed on the outer wall of the rotating shaft 206. The bottom of the 7 has a groove, in which a connector 301 is movably disposed. A threaded rod 302 is movably disposed inside the connector 301 and is movably inserted into the connector 301. A handle 303 is fixedly disposed at one end of the threaded rod 302. Mounting rings 304 are fixedly disposed on both sides of the mounting rod 207. The outer wall of the mounting ring 304 has an external thread. A protective shell 305 is movably disposed outside the mounting ring 304. The inner wall of the protective shell 305 has an internal thread that matches the mounting ring 304. The protective shell 305 is threadedly connected to the mounting ring 304. A mounting plate 307 is fixedly disposed at the bottom of the connector 301, and a fishing net 308 is fixedly disposed on the inner wall of the mounting plate 307.

[0023] In this embodiment, during use, cylinder 202 is activated, and the telescopic end of cylinder 202 drives the lifting plate 203 to move vertically. When the fishing net 308 is fully inside the aquaculture pond 1, cylinder 202 is deactivated, and the waterproof motor is activated. The output shaft of the waterproof motor drives the rotating shaft 206 to rotate, and the mounting plate 307 and the fishing net 308 rotate with the rotating shaft 206, thereby realizing the automatic harvesting of aquatic products in the aquaculture pond 1. At the same time, the moving column 204 moves, thereby automatically moving the fishing net 308 during harvesting to improve harvesting efficiency. When the fishing net 308 is aged, worn, or needs to be replaced, the protective shell 305 is rotated and removed, and then the handle 303 is rotated. The threaded rod 302 rotates within the mounting rod 207. When it is completely removed from the connector 301, the limit of the connector 301 is released. At this time, the mounting plate 307 can be removed, and the fishing net 308 can be maintained. After repair or replacement, insert the connector 301 into the groove, then rotate the handle 303 in the opposite direction until one end of the threaded rod 302 completely penetrates the connector 301. Then, with the help of the nut, the mounting plate 307 is fixed, thus realizing the quick disassembly and installation of the mounting plate 307. This greatly facilitates fishermen in disassembling and replacing the fishing net 308 and reduces resource waste. After the mounting plate 307 is fixed, rotate the protective shell 305 so that it is tightly threaded to the outside of the mounting ring 304, thereby protecting the threaded rod 302 and the handle 303 from external environmental corrosion or damage, extending the service life of the threaded rod 302 and the handle 303, and enhancing the stability and firmness of the mounting plate 307 and the fishing net 308. At the same time, the sealing gasket 306, through its elastic deformation, can further reduce the risk of corrosion of the threaded rod 302 and the handle 303.

[0024] Please see Figures 1 to 4 As shown, one end of the rotating shaft 206 is fixedly connected to the output shaft of the waterproof motor. By setting the rotating shaft 206, when the waterproof motor operates, its output shaft drives the rotating shaft 206 to rotate, thereby enabling precise control of the direction and angle of rotation of the rotating shaft 206, achieving automatic harvesting of aquatic products. A nut is movably installed on the outer wall of the threaded rod 302 at the end away from the handle 303. By setting the threaded rod 302, when the nut is tightened to the appropriate position, it can fix the position of the threaded rod 302, preventing it from moving or loosening due to external forces, thus improving the stability and safety of the threaded rod 302. The protective shell 305 is made of plastic. By setting the protective shell 305, the aquaculture environment is usually quite humid and may contain corrosive substances such as salt. Due to its good corrosion resistance, the plastic material can effectively resist the erosion of these environmental factors, protecting the threaded rod 302 and the handle 303 from damage.

[0025] Please see Figures 1 to 4As shown, sealing gaskets 306 are fixedly installed on the side of the protective shell 305 near the mounting rod 207. The sealing gaskets 306 enhance the seal between the protective shell 305 and the mounting rod 207, thereby protecting the threaded rod 302 and the handle 303 from damage. A light strip 309 is fixedly installed on the upper part of one side of the fixing column 201. The light strip 309 provides good illumination, increasing the brightness of the surrounding environment of the aquaculture pond 1 when needed, facilitating observation and harvesting at night, and improving the harvesting effect of the device.

[0026] Specifically, in this embodiment, by setting a connector 301, a threaded rod 302, and a handle 303, rotating the handle 303 causes the threaded rod 302 to rotate within the mounting rod 207. When the threaded rod 302 is completely removed from the connector 301, the limiting position of the connector 301 is released. At this point, the mounting plate 307 can be removed, and the fishing net 308 can be repaired or replaced. After the operation is completed, the connector 301 is inserted into the groove, and then the handle 303 is rotated in the opposite direction until one end of the threaded rod 302 completely penetrates the connector 301. Then, with the cooperation of the nut, the mounting plate 307 is fixed, thereby realizing the quick disassembly and installation of the mounting plate 307. The operation is simple and effectively improves work efficiency. It not only allows fishermen to easily disassemble and replace the fishing net 308 without replacing other parts, but also greatly simplifies the fishing process. The maintenance process of the fishing net 308 reduces resource waste and significantly lowers maintenance costs. It also helps fishermen select the appropriate fishing net 308 based on the characteristics of farmed aquatic products, optimizes the catch quality, and reduces the risk of damage or escape of aquatic products. By setting up the mounting ring 304, protective shell 305, and sealing gasket 306, after the mounting plate 307 is fixed, the protective shell 305 is rotated to make it tightly threaded to the outside of the mounting ring 304, thereby providing protection for the threaded rod 302 and the handle 303, preventing them from being corroded or damaged by the external environment, extending the service life of the threaded rod 302 and the handle 303, and thus enhancing the stability and firmness of the mounting plate 307 and the fishing net 308. At the same time, the sealing gasket 306, through its elastic deformation, can further reduce the risk of corrosion of the threaded rod 302 and the handle 303.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
