Furthermore, the sealing plate and the annular plate provide a secondary seal for the lower part of the motor, and the insertion point of the transmission shaft into the first housing provides a first seal, significantly increasing the internal sealing degree of the connection between the second and first housings.

[0003] In aquaculture, fish fry may be eaten by birds such as sparrows. If the birds are not driven away in time, the survival rate of the fish fry may be affected. The aforementioned easy-to-install digital aeration device for aquaculture lacks auxiliary structures during use, and its functionality is relatively simple and its practicality is low. Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional oxygenation device for fish farming, which can solve the problem of lack of auxiliary structures and relatively simple functionality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional oxygenation device for fish farming, comprising a mounting plate, a bird deterrent assembly, and a floating assembly. The mounting plate is equipped with a water wheel and a drive motor, the drive motor being used to drive the water wheel to rotate. The bird deterrent assembly is mounted on the mounting plate.

The two sets of transmission gears mesh with each other.

[0008] Preferably, the floating assembly further includes a fixed base plate, a damping limit spring, a linkage plate, a pull rod, and a float. A fixed side block is fixedly installed on the outer wall of the mounting plate, and a float is fixedly installed at one end of the floating rod.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: This multifunctional aeration device for fish farming, driven by a motor, rotates a striking block to strike a striking drum, creating a continuous bird-repelling effect through physical vibration and sound. It effectively drives away birds that prey on fish, such as egrets and kingfishers. In traditional fish farming, bird predation easily leads to losses of fish fry and reduced production of adult fish, especially during the juvenile stage. This bird-repelling design eliminates the need for manual intervention and avoids the pollution of water quality and fish caused by chemical bird repellents. It saves on labor management costs, ensures a safe farming environment and fish survival rates, and reduces economic losses caused by bird predation. To stabilize aquaculture production, the limiting round rod allows for easy separation of the floating rod, float, and mounting plate. The disassembled components are smaller and easier to store neatly, significantly saving warehouse space during off-peak seasons and preventing the entire device from occupying too much storage area. During transportation, the disassembled components can be flexibly stacked, reducing wasted space in transport vehicles and lowering the cost per trip. This is especially suitable for large-scale fishponds that require transporting multiple sets of the device. Furthermore, loading and unloading are easier after disassembly, eliminating the need for large hoisting equipment and reducing the difficulty of transportation and handling. In addition, for subsequent maintenance, corresponding components can be disassembled individually without the need for the entire transport device, improving maintenance convenience.

A fixed side block 601 is fixedly installed on the outer wall of the mounting plate 1. A float 608 is fixedly installed at one end of the floating rod 602. The fixed base plate 603 is fixedly installed at the bottom of the fixed side block 601. A damping limit spring is fixedly installed on the inner bottom of the fixed base plate 603.

This is especially suitable for large-scale fishponds requiring the transport of multiple sets of equipment. Furthermore, disassembly makes loading and unloading easier, eliminating the need for large hoisting equipment and reducing operational complexity. Additionally, subsequent maintenance allows for individual disassembly of specific components without the need for a complete transport system, improving maintenance convenience.

[0017] Working principle: The aforementioned drive motor 4 is existing technology, so its internal structure and control method do not need to be described in detail. In use, the device is placed on the water surface and limited by a rope. The drive motor 4 is then started. The start of the drive motor 4 drives the rotating rod 2 and the water wheel 3 to rotate. The rotation of the water wheel 3 can agitate the water surface, thereby increasing oxygen. When the rotating rod 2 rotates, it can drive the rotating rod 503 to rotate through two sets of transmission gears 507. The rotation of the rotating rod 503 drives the striking block 506 to rotate through the fixed sleeve 504 and the elastic rubber rod 505. The rotation of the striking block 506 can strike the striking drum 502, thereby producing vibration and sound. When it is necessary to disassemble the float rod 602 and the float ball 608, pulling the sliding rod 607 can move the linkage plate 605 and the limiting round rod 606, thereby releasing the limitation between the float rod 602 and the fixed side block 601 and allowing the float rod 602 to be removed.

[0018] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
