A support rod is fixed to one side of the upper clamp, and a connecting seat is installed at one end of the support rod. A motor is installed above the connecting seat, a drive shaft is installed below the motor, and an impeller is installed below the drive shaft.

[0007] Preferably, the second buoy is threadedly connected to the first buoy by the first bolt, and the second buoy has the same shape as the first buoy.

[0008] Preferably, the support rod is threadedly connected to the lower clamp via an upper clamp, and the support rod is evenly spaced on the outside of the connecting seat.

[0009] Preferably, the impeller forms a rotating structure with the connecting seat via a drive shaft, and the central axis of the impeller coincides with that of the connecting seat.

[0010] Preferably, the counterweight mechanism includes a fixed block, a collar, a third bolt, an insert block, and a counterweight block. The fixed block is fixed below the second buoy, and collars are fixed on both sides of the fixed block.

[0011] Preferably, the counterweight block forms a telescopic structure through an insert and a collar, and the insert is an open-hole type.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This oxygenation device for water conservancy projects, through the use of a quick-release mechanism, allows for the rapid installation of the support rod before commissioning by fitting the lower and upper clamps together onto the outside of the first and second buoys and then connecting them with a second bolt. Furthermore, it facilitates disassembly and repair by personnel in case of equipment malfunction, reducing maintenance difficulty and costs. The quick-release design of the support rod also allows the device to be disassembled during transportation, reducing transport volume and weight, facilitating the use of more flexible transport vehicles, and improving transportation efficiency.

[0014] 2.

[0020] 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.

[0021] Please see Figure 1 , Figure 3 and Figure 4 This utility model provides a technical solution: an oxygenation device for water conservancy projects, including a first buoy 1, a first bolt 2 passing through the upper part of the first buoy 1, and a second buoy 3 installed below the first buoy 1. The second buoy 3 is threadedly connected to the first buoy 1 by the first bolt 2. The second buoy 3 has the same shape as the first buoy 1, facilitating the docking and installation of the second buoy 3 and the first buoy 1, and has strong structural flexibility. A quick-release mechanism 4 is installed on the outside of the second buoy 3, and a counterweight mechanism 5 is provided below the second buoy 3. The counterweight mechanism 5 includes a fixing block 501, a collar 502, a third bolt 503, an insert block 504, and a counterweight block 505. The fixed block 501 is fixed below the second buoy 3. Both sides of the fixed block 501 are fixed with collars 502. A third bolt 503 passes through one side of the collar 502. An insert block 504 is installed inside the collar 502. A counterweight block 505 is fixed below the insert block 504. The counterweight block 505 can increase the overall weight of the device, making the second buoy 3 more stable in the water and less susceptible to shaking or displacement due to external factors such as wind and water flow. The counterweight block 505 forms a telescopic structure with the collar 502 through the insert block 504. The insert block 504 is an open-hole type, which helps to simplify the installation process of the entire aeration device and reduce the installation difficulty and cost.

[0022] Please see Figure 1-2The quick-release mechanism 4 includes a lower clamp 401, an upper clamp 402, a second bolt 403, a support rod 404, a connecting seat 405, a motor 406, a drive shaft 407, and an impeller 408. The lower clamp 401 is fitted onto the outside of the second buoy 3. The upper clamp 402 is installed above the lower clamp 401. The second bolt 403 passes through both sides of the upper clamp 402. The support rod 404 is fixed to one side of the upper clamp 402. The support rod 404 is threadedly connected to the lower clamp 401 through the upper clamp 402. The support rod 404 is evenly spaced on the outside of the connecting seat 405. The lower clamp 401 and the upper clamp 402 are fitted together onto the outside of the first buoy 1 and the second buoy 3, and then the second bolt 403 is used for fastening. The connection allows for quick installation of the support rod 404 before it is put into use, and also facilitates disassembly and maintenance by staff in case of subsequent equipment failure. One end of the support rod 404 is equipped with a connecting seat 405, a motor 406 is installed above the connecting seat 405, a drive shaft 407 is installed below the motor 406, and an impeller 408 is installed below the drive shaft 407. The impeller 408 forms a rotating structure with the connecting seat 405 through the drive shaft 407. The central axis of the impeller 408 and the connecting seat 405 are aligned. The motor 406 drives the impeller 408 to rotate, stirring the water surface, agitating the gas film and liquid film, increasing the contact area between gas and liquid, thereby expanding the oxygen concentration gradient in the water and increasing the dissolved oxygen content in the water.

[0023] Working principle: When using this aeration device for water conservancy projects, first connect the external power supply, then put the lower clamp 401 and the upper clamp 402 together on the outside of the first buoy 1 and the second buoy 3, and then connect them with the second bolt 403. This allows for the quick installation of the support rod 404 before use. After that, place the device on the water surface, and the motor 406 drives the impeller 408 to rotate, stirring the water surface, agitating the air film and liquid film, increasing the contact area between gas and liquid, thereby expanding the oxygen concentration gradient in the water and increasing the dissolved oxygen content in the water. When the device is in use, the counterweight 505 increases the overall weight of the device, making the second buoy 3 more stable on the water surface. When the device is not in use, disconnect the external power supply. The motor 406 is model ZD-2HD542. This completes the use of the aeration device for water conservancy projects.
