Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically a detachable water-changing cage for aquatic seedling cultivation. Background Technology

[0002] To improve water exchange efficiency, reduce labor costs, minimize damage to larvae, and ensure stable water quality while meeting the water quality requirements of aquaculture organisms at different growth stages, aquatic seedling water exchange cages have emerged and are continuously being improved and developed.

[0003] Chinese Patent Publication No. CN 216314888 U discloses a detachable aquaculture cage, specifically relating to the field of aquaculture cage technology. Existing aquaculture cages are generally of a fixed size, requiring replacement as the aquatic organisms grow to adapt to their growth environment. However, replacement is cumbersome, and installation is inconvenient, affecting efficiency. This invention provides a fixed plate on the opposite side of each of the two floats, with an adjustment mechanism between the two fixed plates. A culture net is located on the lower surface of the two fixed plates. Rotating the handle causes a threaded rod to rotate, which in turn moves a threaded block. Through the cooperation of the two first and second connecting rods, the distance between the first and second hinged shaft seats is adjusted, thereby adjusting the distance between the two fixed plates. This allows the culture net to be opened or closed, facilitating adjustments to the internal space and improving the adaptability of the aquaculture cage.

[0004] The existing technical solutions mentioned above have the following shortcomings: the operation of the technical solutions during the adjustment process is relatively cumbersome and the efficiency is low. They cannot meet the needs of convenient water exchange in aquaculture, and disassembly and maintenance may not be convenient enough. There is room for optimization. Therefore, it is necessary to design a detachable water exchange cage for aquaculture seedlings to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this utility model is to provide a detachable water changing cage for aquatic seedling raising, so as to solve the problem in the background art that the water changing cage for aquatic seedling raising is inconvenient to disassemble and maintain, and cannot easily change the water.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a detachable aquatic seedling water changing cage, comprising a top cover and support columns. Support columns are uniformly fixedly connected to the bottom of the top cover, and each support column is connected to a vertical column at its bottom. Short and long horizontal bars are fixedly connected between two sets of vertical columns, and a fixing box is connected to the bottom of each support column. A culture tank is provided below the top cover, and the water changing cage body is located inside the culture tank. A replacement seat is fixedly connected inside the water changing cage body, and filter screens are slidably connected inside two sets of replacement seats. A horizontal plate is fixedly connected to the top of the water changing cage body, and a threaded rod is connected to the top of the horizontal plate. A second gear is connected to the top of the top cover, and a threaded sleeve is fixed inside the second gear. The threaded sleeve and the threaded rod are threadedly connected. A first gear is connected to the top of the top cover, and the first and second gears are meshed together. A motor is fixed to the bottom of the top cover, and the output shaft of the motor is connected to the first gear.

[0007] Furthermore, each of the fixing boxes has screw holes inside, and bolts are rotatably connected inside the screw holes, and the bolts are threadedly connected to the column.

[0008] Furthermore, the main body of the water exchange cage is made of PVC, and the filter screen is made of stainless steel.

[0009] Furthermore, filter plates are fixed on both sides of the main body of the water exchange cage, and the filter plates are evenly provided with pores.

[0010] Furthermore, each of the support columns has a positioning column fixed at its bottom end, and each of the columns has a positioning groove at its top end, with the positioning groove connected to the positioning column.

[0011] Furthermore, a drain valve is fixedly connected to one side of the culture tank, and a valve is provided on the outside of the drain valve.

[0012] Furthermore, the size of each positioning post is matched with the size of the positioning groove, and there are four sets of both the positioning groove and the positioning post.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the detachable aquatic seedling water changing cage can efficiently and conveniently change wastewater, and is easy to protect the seedlings, and is simple to operate and convenient to use; By installing filter screens with different pore diameters inside two sets of replacement seats when changing the filter screens, this system can accommodate aquatic seedlings of different sizes and prevent them from flowing away through the pores during water changes. When a water change is needed, the motor is started, driving the first gear and its meshing second gear to rotate simultaneously. This, in turn, moves the threaded rod upward through the threaded sleeve, causing the horizontal plate and the main body of the water changing cage to move upward together. The water inside the culture tank first passes through the filter screens on both sides to allow the aquatic seedlings to pass through, and then flows into the culture tank through the filter plates on both sides of the main body of the water changing cage. Opening the drain valve allows for quick replacement and discharge of aquaculture wastewater. The system is simple to operate, convenient to use, and easy to replace, and is suitable for aquatic seedlings of different sizes, improving its practicality and flexibility.

[0014] The culture tank and the column are assembled by using positioning columns and positioning grooves. Then, the bolts are rotated into the screw holes and fixed to the top of the column to realize the installation connection of the upper and lower components. This prevents the culture tank from being lifted by atmospheric pressure during the water exchange cage's ascent, thus improving the safety of water exchange. Furthermore, the modular components make it easy to disassemble and replace individual components. Attached Figure Description
