Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to an escape-proof net cage for aquaculture. Background Technology

[0002] In aquaculture, escape-proof cages are crucial equipment for ensuring aquaculture safety and improving economic efficiency. Traditional escape-proof cages mostly adopt a fixed structure, secured to the bottom of the water by anchor ropes or weights. This method is not only difficult to move and adapt to changes in water quality and water management needs, but also prone to displacement under the impact of water flow, leading to cage damage or aquatic escape. In addition, during long-term use, the bottom of the cages easily accumulates uneaten feed, algae, and aquatic excrement. Existing cleaning methods usually require manual diving or complete disassembly of the cage, which is cumbersome and inefficient, increasing labor intensity and potentially damaging the cage structure, affecting its service life. Furthermore, some cages have open tops, failing to effectively prevent the invasion of birds and other predators, resulting in aquaculture losses. As aquaculture develops towards large-scale and intelligent operations, there is a need for escape-proof cages that can be easily moved and fixed, have efficient cleaning capabilities, and offer strong protection to meet the needs of modern aquaculture.

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0004] Therefore, the purpose of this utility model is to provide an escape-proof net cage for aquaculture, which can solve the problems of inconvenience in fixing and moving existing traditional net cages and difficulty in cleaning the bottom of the net cage.

[0005] To solve the above-mentioned technical problems, this utility model provides an escape-proof net cage for aquaculture, which adopts the following technical solution: it includes a base, a support frame is fixedly connected to the upper end of the base, a cover plate is provided at the upper end of the support frame, a net cage body is fixedly connected to the inner wall of the support frame, a movable part is fixedly connected to the outer side of the base, a threaded rod is threadedly connected to the inner wall of the movable part, a rotating part is provided at the upper end of the threaded rod, a crank is provided at the upper end of the rotating part, a fixed part is rotatably connected to the outer surface of the rotating part, a through cleaning groove is provided inside the base, and a cleaning mechanism is provided inside the cleaning groove; The cleaning mechanism includes a slide rail, a cleaning block, a threaded head, and a cleaning brush.

[0006] Optionally, a fixing rod is fixedly connected to the lower end of the fixing member, and an insertion block is fixedly connected to the lower end of the fixing rod. There are two fixing rods, which are symmetrically distributed on both sides of the threaded rod.

[0007] The above technical solution enhances the stability of the cage during fixation. When the threaded rod pushes the insertion block into the bottom of the water, the symmetrical fixing rod and insertion block provide support from both sides, preventing the cage from shaking or shifting due to water flow impact, aquatic activities, and other factors, thus ensuring the stability of the cage during the aquaculture process.

[0008] Optionally, the number of the movable parts is two and they are symmetrically distributed on both sides of the base, and the number of the threaded rods is two and they correspond one-to-one with the movable parts.

[0009] The above technical solution allows for easy adjustment of the cage's position by synchronously rotating the handles on both sides, ensuring stability during movement.

[0010] Optionally, slide rails are provided on both sides of the cleaning groove, and sliders are slidably connected to the inner walls of the slide rails. The inner walls of the sliders are fixedly connected to the cleaning blocks.

[0011] The above technical solution provides guidance for the movement of the cleaning block, ensuring that the cleaning block can slide smoothly along a straight line when cleaning the bottom of the cage, and avoiding the cleaning block from shifting or getting stuck during the movement.

[0012] Optionally, a pull rod is fixedly connected to the rear end of the cleaning block, and a pull plate is fixedly connected to the rear end of the pull rod.

[0013] The above technical solution allows the cleaning block to slide on the slide rail, thereby cleaning the bottom of the cage.

[0014] Optionally, the upper end of the cleaning block is provided with a threaded groove, and the inner wall of the threaded groove is threadedly connected to the threaded head.

[0015] With the above technical solution, when replacement is needed, simply rotate the threaded head to remove it from the cleaning block, making it convenient and quick to replace with a new cleaning brush, saving maintenance time and costs, and also facilitating the separate maintenance and management of the cleaning brush.

[0016] Optionally, a mounting plate is fixedly connected to the upper end of the threaded head, and a cleaning brush is fixedly connected to the upper end of the mounting plate.

[0017] The above technical solution can be firmly connected to the cleaning block and will not loosen or fall off due to friction, vibration or other factors during the cleaning process.

[0018] Optionally, the number of cleaning brushes is multiple and they are evenly distributed on the upper end of the cleaning block, and the upper surface of the cleaning brushes is in contact with the lower surface of the cage body.

[0019] The above technical solution involves multiple cleaning brushes evenly distributed, which can cover a larger area at the bottom of the cage, cleaning algae, uneaten bait and other dirt at the bottom of the cage without dead angles.

[0020] In summary, this utility model has at least one of the following beneficial effects: 1. Highly efficient escape prevention and safe aquaculture: The base, support frame, cover plate and net cage body form a fully enclosed structure, creating a solid aquaculture space that effectively prevents fish, shrimp and crabs from escaping. At the same time, the cover plate can block the invasion of natural enemies such as birds, providing a safe growth environment for aquatic products and reducing aquaculture losses.

[0021] 2. Automated cleaning reduces maintenance costs. The cleaning mechanism, consisting of a sliding rail, cleaning blocks, and cleaning brushes in the cleaning tank, allows the cleaning brushes to clean the bottom of the net cage by simply pulling the lever and the plate. This effectively removes attached algae, uneaten feed, and other impurities, keeps the water flowing smoothly in the net cage, and reduces water quality deterioration and disease transmission caused by the accumulation of dirt. Moreover, the cleaning brushes are connected to the cleaning blocks via threaded heads, making them easy to disassemble and replace, which greatly reduces the frequency of manual cleaning and maintenance costs.

[0027] The lower end of the fixing member 6 is fixedly connected to a fixing rod 10, and the lower end of the fixing rod 10 is fixedly connected to an insertion block 11. There are two fixing rods 10, which are symmetrically distributed on both sides of the threaded rod 9. There are two moving parts 5, which are symmetrically distributed on both sides of the base 1. There are two threaded rods 9, which correspond one-to-one with the moving parts 5.

[0028] The cleaning mechanism includes a slide rail 4, a cleaning block 13, a threaded head 20, and a cleaning brush 18. Slide rails 4 are provided on both sides of the cleaning groove 17. A slider 12 is slidably connected to the inner wall of the slide rail 4. The inner wall of the slider 12 is fixedly connected to the cleaning block 13. A pull rod 14 is fixedly connected to the rear end of the cleaning block 13. A pull plate 16 is fixedly connected to the rear end of the pull rod 14. A threaded groove 19 is provided at the upper end of the cleaning block 13. The inner wall of the threaded groove 19 is threadedly connected to the threaded head 20. An installation plate 15 is fixedly connected to the upper end of the threaded head 20. A cleaning brush 18 is fixedly connected to the upper end of the installation plate 15.

[0029] Working principle: When using this aquaculture escape-proof net cage, first move the net cage to a suitable water area, turn the crank handle 7 clockwise, and the rotating part 8 will drive the threaded rod 9 to rotate. The threaded connection between the moving part 5 and the threaded rod 9 will cause the threaded rod 9 to push the insertion block 11 down and insert it into the bottom mud layer. The symmetrical fixing rods 10 and the insertion block 11 on both sides, together with the fixing part 6, will firmly fix the base 1. During the aquaculture process, if algae, uneaten feed, or other dirt are found attached to the bottom of the net cage, the pull rod 14 and pull plate 16 at the rear end of the cleaning block 13 can be pulled to move the cleaning block 13 along the slide rails 4 on both sides of the cleaning groove 17 via the slider 12. The multiple cleaning brushes 18 connected to the upper end of the cleaning block 13 via the threaded head 20 and threaded groove 19 will then rub against the lower surface of the net cage body 3 to complete the cleaning. If the worn cleaning brush 18 needs to be replaced, the threaded head 20 can be unscrewed to disassemble and replace it. When it is necessary to move the net cage, turn the crank handle 7 counterclockwise to retract the threaded rod 9 and the insertion block 11 upwards to release the fixation, and then the net cage can be moved to the new aquaculture area.

[0030] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
