[0022] 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.

[0023] Please see Figure 1-5 One embodiment of this utility model is a fish farming harvesting device, comprising:

[0024] The handle 1 has a mesh frame 11 welded to one end, which is made of high-strength steel structure and is more sturdy and stable in use.

[0025] The positioning component 3 includes a bearing ring 31, the outer wall of which is welded to the inner wall of the grid frame 11 via a welding column 32. A pressure ring 33 is fixedly connected to the top of the bearing ring 31 via screws 5. A limiting groove 35 is formed on the upper surface of the bearing ring 31, and a traction column 36 is fixedly connected to the center of the limiting groove 35. A rubber ring 4 is sleeved on the outside of the traction column 36. The top of the net body 2 is sleeved on the outside of the traction column 36. Through the setting of this installation structure, the device can meet the disassembly and replacement operation of the net body 2 by inexperienced personnel, thereby improving the convenience of its subsequent use and maintenance.

[0026] Furthermore, both the space frame 11 and the positioning component 3 are annular structures, and the diameter of the handle 1 is larger than the diameter of the bearing ring 31. The pressure ring 33 also has a limiting groove 35 on the side near the bearing ring 31, and the limiting groove 35 has a limiting hole for the rubber ring 4 and the traction column 36. The limiting groove 35 on the lower surface of the pressure ring 33 further satisfies the locking and positioning of the net body 2. At the same time, the insertion of the traction column 36 and the pressure ring 33 completes the auxiliary positioning of the top of the net body 2 and ensures that the net body 2 is inside the limiting groove 35, avoiding excessive compression of the net body 2 and causing it to break. This improves the installation stability of the net body 2, avoids wear, and increases its service life.

[0027] Furthermore, the outer wall of the pressure ring 33 is integrally formed with a locking block 34. The locking block 34 has a T-shaped structure, and the locking block 34 and the welding column 32 engage and position each other. Through the engagement and positioning of the welding column 32 and the locking block 34, the pre-positioning function is achieved, which facilitates the quick alignment of the bearing ring 31 and the pressure ring 33.

[0028] Furthermore, the corners of the limiting groove 35 are arc-shaped to reduce wear on the net body 2. Each traction column 36 is fitted with a rubber ring 4. The rubber ring 4 is mainly used to assist in the tightening of the net body 2 during installation, so as to avoid the net body 2 from falling off in some places during installation, thereby improving the ease of installation of the device. The radius of the net wire of the net body 2 is not greater than the depth of the limiting groove 35.

[0029] Furthermore, the upper surface of the bearing ring 31 is provided with a threaded hole 38, and the threaded hole 38 has a non-through structure. The pressure ring 33 is provided with a stepped hole 37 corresponding to the threaded hole 38. A screw 5 passes through the stepped hole 37 and is threadedly connected to the threaded hole 38. The height of the screw 5 is not greater than the diameter of the pressure ring 33. There are eight sets of screws 5, and each set of screws 5 is located at the center line of the adjacent welded column 32. A sealing ring is provided on the outside of the screw 5. The installation of the screw 5 completes the sealing and compression of the bearing ring 31 and the pressure ring 33. At the same time, the sealing ring ensures the sealing performance of the screw 5 after installation. Furthermore, the non-through structure of the threaded hole 38 effectively waterproofs the screw 5, preventing it from being frequently submerged in water and causing corrosion, thereby ensuring the flexibility of subsequent disassembly.

[0030] Working principle: The handle 1, net frame 11 and net body 2 used in this application are all products that can be purchased directly from the market. Their principles and connection methods are existing technologies known to those skilled in the art, so they will not be described in detail here. When using this utility model, the net body 2 is first installed. After removing the pressure ring 33, the top of the net body 2 is fitted onto the outside of the traction column 36. At the same time, a rubber ring 4 is fitted onto the top of the traction column 36 to achieve auxiliary compression of the net body 2 and prevent the net body 2 from falling off. After the top of the net body 2 is fully engaged and positioned, the pressure ring 33 is sealed and pressed against the top of the bearing ring 31.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
