[0032] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0033] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0034] Reference Figures 1-6 As shown, a disinfection device for aquaculture ponds includes: a tank 100 for storing disinfectant, a self-priming pump 102 whose input end is connected to the tank 100 via a water pumping pipe 101, and multiple sets of nozzles 104 for spraying disinfectant via an outlet pipe 103 connected to the output end of the self-priming pump 102; wherein, a floating component 200 is fixedly provided on the bottom surface of the tank 100, which can drive the tank 100 to float on the water surface, and each set of nozzles 104 is installed on the floating component 200 via a corresponding swing mechanism 300 and can swing back and forth in the vertical direction.

[0035] In use, the entire disinfection device is placed on the surface of the aquaculture pond. The float 200 allows the tank 100 and its auxiliary equipment to float stably on the water. Power is connected or the relevant mechanisms are activated, causing the self-priming pump 102 to start working. The self-priming pump 102 draws disinfectant from the tank 100 through the suction pipe 101. The drawn disinfectant is then transported through the outlet pipe 103 to multiple sets of nozzles 104. Each set of nozzles 104 swings back and forth vertically via the swing mechanism 300, ensuring that the disinfectant is evenly sprayed to every corner of the aquaculture pond. As the float 200 moves on the water surface, the disinfection device can cover a wider area, achieving a comprehensive disinfection effect. The float 200 allows the disinfection device to move freely on the water surface, and combined with the swinging function of the nozzles 104, it can cover a wider disinfection area. The swinging mechanism 300 ensures that the disinfectant is evenly sprayed to water at different heights, improving the uniformity of disinfection.

[0036] Reference Figures 1-3 As shown, the floating component 200 includes: a main float 201, secondary floats 202, and a propeller 203; wherein, the bottom surface of the box 100 is fixedly provided with a main float 201 whose bottom surface is in contact with the water surface, multiple sets of secondary floats 202 are fixedly provided on the two sides of the main float 201 that are far apart from each other, and a propeller 203 that drives the main float 201 to move and controls the direction of movement is fixedly provided on the other side of the main float 201.

[0037] In the above scheme, the disinfection device is placed on the surface of the aquaculture pond via a main float 201. The bottom surface of the main float 201 is in contact with the water surface to ensure stable buoyancy. Multiple sets of secondary floats 202 are fixed on both sides of the main float 201 to provide additional buoyancy and stability, preventing excessive swaying of the device under wind, waves, or currents. A propeller 203 is fixed to one side of the main float 201. By driving the propeller 203 to rotate, the main float 201 and the disinfection device on it can be moved on the water surface. Simultaneously, by adjusting the rotation direction and speed of the propeller 203, the movement direction and speed of the disinfection device can be controlled. The addition of the propeller 203 allows the disinfection device to move autonomously on the water surface, thereby achieving disinfection of different areas and improving the flexibility and efficiency of disinfection.

[0038] Reference Figure 2 As shown, the swing mechanism 300 includes a support frame 301 and a fixed rod 302. The support frame 301 is fixedly installed on the main float 201. The fixed rod 302 is rotatably provided on the support frame 301. The nozzle 104 is fixedly installed on one end of the fixed rod 302 located on the water surface. The main float 201 is provided with a swinging component for driving the fixed rod 302 to rotate around the support frame 301.

[0039] In the above scheme, the main float 201 is equipped with a swinging component to drive the fixed rod 302 to rotate around the support frame 301. When the swinging component is activated, it drives the fixed rod 302 and the nozzle 104 to swing back and forth in the vertical direction. During the swinging process, the nozzle 104 continuously sprays disinfectant, forming a fan-shaped or cone-shaped spray range. Because the nozzle 104 is swinging, the disinfectant can cover a wider area. This allows the disinfectant to be sprayed evenly to water at different heights, improving the uniformity of spraying and the disinfection effect.

[0040] Reference Figures 2-6 As shown, the driving component includes: a driving disc 304, a driving rod 305, a first driving bevel gear 308, and a first driven bevel gear 309; wherein, a limiting groove 303 is provided at one end of the fixed rod 302 away from the nozzle 104, a rotating shaft 306 is rotatably provided on the main float 201 via a bracket, the top end of the rotating shaft 306 is fixedly provided with the driving disc 304, and a driving rod 305 that slides through the limiting groove 303 is fixedly provided on the surface of the driving disc 304 near its circumferential edge, and a driving component for driving the rotating shaft 306 to rotate is fixedly provided on the main float 201.

[0041] In the above scheme, when the drive unit is activated, it drives the rotating shaft 306 to rotate. Since the drive disk 304 is fixedly mounted on the rotating shaft 306, the drive disk 304 will also rotate accordingly. As the drive disk 304 rotates, the drive rod 305 on it will slide in the limiting groove 303, thereby pushing the fixed rod 302 to rotate around the support frame 301. Since the fixed rod 302 is fixedly connected to the nozzle 104, when the fixed rod 302 rotates, the nozzle 104 will also swing back and forth in the vertical direction to achieve uniform spraying of disinfectant.

[0042] Reference Figure 6 As shown, the driving component includes: a drive motor 307, a first driving bevel gear 308, and a first driven bevel gear 309; wherein, the drive motor 307 is fixedly mounted on the main float 201, the output shaft of the drive motor 307 is horizontally arranged and a rotating shaft 306 is fixedly sleeved on its top end, one end of the rotating shaft 306 is fixedly sleeved with a first driven bevel gear 309 that meshes with the first driving bevel gear 308, and the two sets of rotating shafts 306 are connected by a transmission belt 310.

[0043] In the above scheme, firstly, the drive motor 307 is started. The output shaft of the drive motor 307 is horizontally positioned, and a rotating shaft 306 is fixedly sleeved at its top. Therefore, when the drive motor 307 starts, it drives the rotating shaft 306 to rotate. A first driven bevel gear 309 is fixedly sleeved at one end of the rotating shaft 306, and a first driving bevel gear 308 meshes with the first driven bevel gear 309. Therefore, when the rotating shaft 306 rotates, it drives another set of rotating shafts 306 to rotate through the meshing transmission of the first driven bevel gear 309 and the first driving bevel gear 308. Multiple nozzles 104 in the device need to swing synchronously, and multiple sets of rotating shafts 306 are connected by a transmission belt 310. In this way, when one set of rotating shafts 306 rotates, it will drive other sets of rotating shafts 306 to rotate synchronously through the transmission belt 310. As the rotating shafts 306 rotate, the drive disc 304 and the drive rod 305 will push the fixed rod 302 and the nozzle 104 to swing back and forth in the vertical direction, so as to achieve uniform spraying of disinfectant.

[0044] Reference Figures 1-3 As shown, the box 100 is equipped with a mixing mechanism 400 for stirring the liquid to promote mixing when preparing disinfectant solution.

[0045] When preparing disinfectant solution, pour disinfectant and water or other solvents into the container 100, turn on the power to the rotary motor 401, and start the mixing mechanism 400 to stir the disinfectant solution in the container 100, promoting uniform mixing. This ensures that the disinfectant solution is thoroughly stirred during the preparation process, thereby improving mixing efficiency and ensuring the uniformity of the disinfectant solution.

[0046] Reference Figures 4-5 As shown, the mixing mechanism 400 includes: a second driving bevel gear 402, a second driven bevel gear 403, a central control shaft 404, and stirring rods 406; wherein, the central control shaft 404 rotatably passes through the housing 100, and multiple sets of suction holes 405 are opened on the circumferential surface of the central control shaft 404 near the bottom surface of the housing 100. The water suction pipe 101 passes through the central control shaft 404 and communicates with the suction holes 405, and multiple sets of stirring rods 406 are fixedly installed on its circumferential surface near the top surface of the housing 100. The second driven bevel gear 403 is fixedly sleeved on one end of the central control shaft 404 that passes through the housing 100. A rotary motor 401 is fixedly installed on the housing 100. The output shaft of the rotary motor 401 is horizontally arranged and the top end is fixedly sleeved with a second driving bevel gear 402 that meshes with the second driven bevel gear 403.

[0047] In the above scheme, after the rotary motor 401 is started, its output shaft drives the second driving bevel gear 402 to rotate. The second driving bevel gear 402 meshes with the second driven bevel gear 403, so the second driven bevel gear 403 will rotate accordingly. The second driven bevel gear 403 is fixedly sleeved on the central control shaft 404, so the central control shaft 404 will also rotate with the rotation of the second driven bevel gear 403. The stirring rod 406 on the central control shaft 404 rotates accordingly, stirring the disinfectant in the box 100. During the stirring process, the multiple sets of suction holes 405 on the circumferential surface of the central control shaft 404 near the bottom surface of the box 100 can further promote the mixing of the disinfectant. When the central control shaft 404 rotates, the suction holes 405 can suck in the disinfectant at the bottom of the box 100 and deliver the disinfectant through the water suction pipe 101 inside the central control shaft 404, and then spray disinfectant through the water outlet pipe 103 and the nozzle 104.

[0048] Reference Figures 4-5 As shown, a filter plate 408 is fixedly installed inside the housing 100, and a central control shaft 404 rotates through the filter plate 408. A stirring blade 409 is fixedly installed on the circumferential surface of the central control shaft 404 below the filter plate 408.

[0049] In the above scheme, as the central control shaft 404 rotates, the stirring blades 409 located below the filter plate 408 also rotate, stirring the disinfectant at the bottom of the tank 100 to ensure that the disinfectant is fully mixed in every corner of the tank 100. The filter plate 408 prevents larger impurities or particles from entering the suction hole 405 and causing blockage of the device.

[0050] Reference Figure 5 As shown, a scraper 407 that abuts against the inner sidewall of the housing 100 is fixedly sleeved on the central control shaft 404.

[0051] In the above scheme, as the central control shaft 404 rotates, the stirring blades 409 located below the filter plate 408 stir the disinfectant at the bottom of the tank 100. At the same time, the scraper 407, which is fixedly sleeved on the central control shaft 404, rotates together with the central control shaft 404 to scrape off residual disinfectant or impurities on the inner wall of the tank 100, preventing them from accumulating and affecting the mixing effect of the disinfectant.

[0052] In summary, the aquaculture pond disinfection device provided by this utility model ensures that an appropriate amount of disinfectant and clean water have been added to the tank 100 during use. If on-site preparation of disinfectant solution is required, the rotary motor 401 can be started. The output shaft of the rotary motor 401 drives the central control shaft 404 to rotate through the meshing of the second driving bevel gear 402 and the second driven bevel gear 403. The stirring rod 406 and stirring blade 409 on the central control shaft 404 will rotate accordingly, stirring the liquid in the tank 100 to ensure that the disinfectant and water are fully mixed. At the same time, the suction hole 405 on the central control shaft 404 can be connected to the self-priming pump 102 through the water pumping pipe 101, allowing the self-priming pump 102 to draw disinfectant solution from the tank 100 when needed. The device floats on the water surface of the aquaculture pond through the main float 201, the secondary float 202, and the propeller 203. The main float 201 ensures stable buoyancy of the device, the secondary float 202 provides additional buoyancy, and the propeller 203 drives the device to move on the water surface and controls the direction of movement. When the device moves to the area requiring disinfection, the self-priming pump 102 is activated. The self-priming pump 102 draws disinfectant from the tank 100 through the pump pipe 101, and then delivers it to multiple sets of nozzles 104 through the outlet pipe 103. Each set of nozzles 104 is mounted on the float 200 via a swing mechanism 300. The drive motor 307 drives the fixed rod 302 to rotate around the support frame 301 through the transmission of the rotating shaft 306, the first active bevel gear 308 and the first driven bevel gear 309, so that the nozzle 104 swings back and forth in the vertical direction to achieve a wider disinfection coverage. If it is necessary to stir or filter the disinfectant in the tank 100 again while or before the disinfectant is sprayed, the rotary motor 401 can be started to stir. At the same time, the stirring blade 409 on the central control shaft 404 will continue to work. The filter plate 408 fixedly installed in the tank 100 can filter out impurities in the disinfectant to ensure that the sprayed disinfectant is purer. During the process of disinfectant spraying and stirring, the scraper 407 fixedly sleeved on the central control shaft 404 will abut against the inner wall of the tank 100 to clean the inner wall of the tank 100 and prevent disinfectant residue or scale.
