[0019] This utility model combines [the following] when cleaning phytoplankton: Figures 1 to 4 A phytoplankton removal device for aquaculture ponds includes a main body 1, a support frame 6 on one side of the main body 1, a connecting frame 7 connected to one side of the support frame 6, a floating block 8 inside the support frame 6, a first suction head 9 inside the floating block 8, a submersible pump 25 fixedly installed at the lower end of the support frame 6, a second suction head 24 connected to one end of the submersible pump 25, a pump motor 12 on one side of the main body 1, the first suction head 9 connected to the pump motor 12 via a hose 11, a filter plate 30 inside the connecting frame 7, and sprockets 28 rotating on both sides inside the connecting frame 7, the two sprockets 28 being connected by a chain 27. Driven by the first motor, a scraper 29 is fixedly mounted on the surface of the chain 27. The scraper 29 contacts the surface of the filter plate 30. The inner cavity of the support frame 6 is provided with sliding grooves 10 on both sides. Sliding sliders 31 are slidably mounted in both sliding grooves 10. The two sliding sliders 31 are fixedly connected to both sides of the floating block 8 to limit the floating block 8. The floating block 8 is always located on the water surface. The upper end of the main body 1 is provided with a waterproof shell 2. The waterproof shell 2 is provided with a battery 3. The upper ends of the waterproof shell 2 are provided with solar panels 4 and controllers 5 on both sides. The lower end of the main body 1 is provided with a propeller 17 to power and drive the device, making the device more practical.

[0020] A conveying pipe 26 is provided above the filter plate 30, and the conveying pipe 26 is connected to the submersible pump 25. A conveyor belt 21 is provided below the filter plate 30. Rollers are provided on both sides of the conveyor belt 21. The rollers are driven by a second motor. The left roller is connected to the connecting frame 7. An opening is provided on one side of the main body 1. The conveyor belt 21 passes through the opening. The right roller is connected to the inner wall of the main body 1. Support plates 22 are provided on both sides of the two rollers. One side of the two support plates 22 is fixedly connected to the connecting frame 7, and the other end is connected to the right roller. Two hydraulic rods 23 are provided at the lower end of the main body 1. The telescopic ends of the two hydraulic rods 23 are fixedly connected to the two support plates 22 respectively to clean the middle and lower layers of diatoms.

[0021] The inner cavity of the main body 1 is provided with a first filter screen 15 and a second filter screen 16 from top to bottom. A water pipe 13 is provided above the first filter screen 15 and is connected to the pump 12. Several water outlets 14 are provided on the water pipe 13.

Floating airbags 18 are provided around the lower end of the main body 1 to collect phytoplankton.

[0022] In actual use, the solar panel 4 has stored electrical energy in the battery 3 in advance to power the various components of the device. After the device is started, the propeller 17 rotates, driving the main body 1 to move in the aquaculture pond according to the set path. The floating airbag 18 at the lower end of the main body 1 ensures that it floats stably on the water surface.

[0023] At this time, the floating block 8 inside the support frame 6 slides in the chute 10 through the slider 31 under the action of buoyancy, always keeping the first suction head 9 at the surface of the water.

The water containing phytoplankton is first filtered by the first filter screen 15 to remove the larger phytoplankton groups, and then by the second filter screen 16 to intercept the small single-celled algae. The filtered clear water is guided by the guide block 20 and flows back to the aquaculture pond through the drain pipe 19 to realize water circulation.

[0024] Simultaneously, the submersible pump 25 at the lower end of the support frame 6 is activated, and the second suction head 24 penetrates into the middle and lower layers of water. The operator can adjust the extension and retraction of the hydraulic rod 23 through the controller 5 to change the tilt angle of the support plate 22, specifically suctioning phytoplankton such as diatoms. The water containing algae is transported to the filter plate 30 in the connecting frame 7 through the delivery pipe 26. The filter plate 30 filters the water, and the trapped phytoplankton remains on the surface of the filter plate 30. The first motor drives the sprocket 28 to rotate, and the chain 27 drives the scraper 29 to move synchronously, scraping the algae on the filter plate 30 onto the conveyor belt 21 below. The second motor drives the roller to rotate, and the conveyor belt 21 transports the trapped phytoplankton through the opening on one side of the main body 1 into the interior of the main body 1 for centralized collection, achieving efficient cleaning of phytoplankton in different water layers.
