[0002] At present, in the sunny summer, the density of algae in aquaculture ponds is always high. Due to the rapid metabolism during the high temperature period, if the nutrition is not supplemented in time and unbalanced, the algae will age and die in large quantities every day. The dead algae consume a lot of oxygen when decomposing, and produce toxic substances such as hydrogen sulfide, which can cause poisoning and death of farmed animals in severe cases; the long-term excessive reproduction of algae can make the pH of the pond water as high as 9-10, and cause low dissolved oxygen or hypoxia in the pond water at night, causing hypoxia floating or suffocation, and at the same time reducing the immunity of farmed animals, creating conditions for the outbreak of other diseases; the algae toxins produced by algae not only inhibit the growth and reproduction of other beneficial algae, but also cause farmed animals to be poisoned by algae toxins and induce diseases.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Reference Figures 1 to 6 The present invention discloses an automatic algae removal device for aquaculture ponds, comprising:

[0039] The motor bracket 2 is fixed in the center of the breeding pond;

[0040] The rotating base 1 is rotatably arranged on the motor bracket 2, and the rotating base 1 is transmission-connected with the first driving part;

[0041] The algae scraping and suction plate assembly 6 is escalable and arranged on the crossbeam 9, and one end of the crossbeam 9 is fixedly connected to the side wall of the rotating base 1;

[0042] The algae crushing and separation component is fixedly arranged at one end of the cross beam 9 away from the rotating base 1, and the liquid inlet end of the algae crushing and separation component is connected with the liquid outlet end of the algae scraping and suction plate component 6 through an algae conveying pump pipeline;

[0043] The oxygenation component is arranged at the bottom of the motor bracket 2 and is used to increase the oxygen content of the pool bottom water.

[0044] When in use, after fixing the motor bracket 2 at the center of the breeding pond, the rotating base 1 is driven to rotate by the first driving part, and the algae scraper and suction plate assembly 6 is driven to make a circular motion in the breeding pond through the cross beam 9. The algae scraper and suction plate assembly 6 can be raised and lowered on the cross beam 9, so that the algae scraper and suction plate assembly 6 can not only scrape and collect the algae growing on the bottom of the pond and the bottom plate, but also be set on the water surface to collect dead algae floating on the surface of the water body. The collected algae is transported to the algae crushing and separation assembly through the algae transporting pump pipeline, and the algae crushing and separation assembly crushes the algae and separates it from the water. The water separated from the algae returns to the breeding pond, thereby realizing automatic algae removal in the breeding pond.

[0045] A plurality of algae scraping and suction plate assemblies 6 can be provided to improve the algae removal effect. In the present invention, three algae scraping and suction plate assemblies 6 are preferred.

[0046] According to a further optimized solution, the first driving unit includes a first motor 3 , a fixed end of the first motor 3 is fixedly connected to the motor bracket 2 , and an output shaft of the first motor 3 is axially connected to the bottom of the rotating base 1 .

[0047] Further optimization scheme, a collecting tank 25 is provided in the algae scraping and suction plate assembly 6, and the collecting tank 25 is a trapezoidal structure, the lower end of the slope of the collecting tank 25 is arranged on the water-facing surface, and the upper end of the collecting tank 25 is provided with a plurality of algae transport holes 23 arranged side by side, and the algae transport holes 23 are evenly spaced and arranged on the top of the algae scraping and suction plate assembly 6; the liquid inlet end of the algae transport pumping pipeline is connected with the plurality of algae transport holes 23;

[0048] An algae scraping part is provided at the bottom of the algae scraping suction plate assembly 6 .

[0049] In a further optimized solution, the algae scraping part includes a sliding groove 27, which is horizontally opened at the bottom of the algae scraping suction plate assembly 6, and the sliding groove 27 is located below the collecting groove 25;

[0050] A slider 29 is slidably connected in the sliding groove 27, a scraper plate 28 is fixedly connected to one end of the slider 29, and an elastic part is provided at the other end of the slider 29;

[0051] One end of the scraper plate 28 extends out of the sliding groove 27, and a pressure block 26 is fixed to the lower end of the collecting groove 25. The bottom end of the pressure block 26 abuts against the top of the scraper plate 28 located outside the sliding groove 27. The pressure block 26 is used to bend the scraper plate 28 located outside the sliding groove 27 to abut against the bottom of the breeding pond.

[0052] According to a further optimized solution, the elastic part includes a compression spring 30 , one end of the compression spring 30 is fixedly connected to the inner wall of the sliding groove 27 , and the other end of the compression spring 30 is fixedly connected to the end of the slider 29 .

[0053] When in use, the bottom of the algae scraper and suction plate assembly 6 contacts the bottom of the pool, and the slider 29 arranged in the sliding groove 27 is used to be fixedly connected to the end of the scraper plate 28. The compression spring 30 can push the slider 29 to push the other end of the scraper plate 28 out of the sliding groove 27 and contact the pressure block 26. The pressure block 26 bends the extended scraper plate 28 so that its end is bent and abuts against the bottom of the pool to scrape off the algae. As the algae scraper and suction plate assembly 6 moves, the compression spring 30 can keep the end of the scraper plate 28 abutting against the bottom of the pool, and the scraper plate 28 is damaged due to friction. At this time, the compression spring 30 is further released, and the end of the scraper plate 28 located on the outside continues to abut against the bottom of the pool to ensure the algae scraping effect.

[0054] During the movement of the algae scraping and suction plate assembly 6, the lower end of the slope of the collecting tank 25 is located on the water-facing side, so that the scraped algae and water can be collected in the collecting tank 25, and the water containing algae in the collecting tank 25 can be sucked out through each algae transport hole 23 and the algae transport pumping pipeline, so that algae can be continuously collected in the collecting tank 25.

[0055] Further optimizing the scheme, a diversion protrusion 24 is provided between two adjacent algae transport holes 23, and the diversion protrusion 24 is fixedly connected to the high end inner wall of the collecting tank 25;

[0056] The middle portion of the diverter protrusion 24 protrudes away from the inner wall of the collecting groove 25 , and the diverter protrusion 24 is used to guide the liquid from the middle portion of the diverter protrusion 24 to both ends.

[0057] A diverter protrusion 24 is arranged between the two algae transport holes 23. The diverter protrusion 24 is used to guide the liquid from the middle of the diverter protrusion 24 to both ends. When the algae-containing water contacts the middle of the diverter protrusion 24, it can move toward the algae transport hole 23 under the diverting action of the diverter protrusion 24, thereby ensuring the algae absorption effect of the algae transport pumping pipeline of the algae transport hole 23.

[0058] To further optimize the solution, the top of the algae scraping and suction plate assembly 6 is fixedly connected to the bottom ends of several connecting rods 7 arranged side by side, the connecting rods 7 are vertically slidably connected to the cross beam 9, the distance between two adjacent connecting rods 7 is equal, and the connecting rods 7 are vertically limited by the cross beam 9 through the top screw.

[0059] By sliding the connecting rod 7 on the cross beam 9, the position of the algae scraper and suction plate assembly 6 can be adjusted so that it can scrape the algae on the bottom of the pool and collect the algae on the water surface. After adjusting the height of the algae scraper and suction plate assembly 6, the connecting rod 7 and the cross beam 9 can be fixed by the top screw.

[0060] According to a further optimized solution, the algae crushing and separation component includes a crushing box 10, a top side of the crushing box 10 is connected to the liquid outlet end of the algae pumping pipeline, a crushing part is provided inside the crushing box 10, and a flotation separation part is provided at the bottom of the crushing box 10, and the flotation separation part is connected to the culture pond.

[0061] According to a further optimized solution, the crushing part includes a third motor 11, the fixed end of the third motor 11 is fixedly connected to the top of the crushing box 10, the output shaft of the third motor 11 is axially connected to one end of a transmission rod 14, and the other end of the transmission rod 14 is axially connected to a cutting knife 20;

[0062] The cutting knife 20 is provided with a filter cartridge 13 on its outer sleeve. The top of the filter cartridge 13 is placed on a filter cartridge support ring 12 . The filter cartridge support ring 12 is vertically limited and matched with the filter cartridge 13 . The filter cartridge support ring 12 is axially connected to the middle of the crushing box 10 .

[0063] A further optimized solution is that the flotation separation part includes an aeration separation cylinder 15, which is axially connected to the bottom of the crushing box 10, and the bottom of the crushing box 10 is connected to the top of the aeration separation cylinder 15. A plurality of leakage holes 19 are opened at the bottom of the aeration separation cylinder 15, and the plurality of leakage holes 19 are circumferentially evenly spaced at the bottom of the aeration separation cylinder 15. An aeration head 18 is provided at the center of the bottom of the aeration separation cylinder 15, and the aeration head 18 is connected to an air pump 16 through an air pipe 17, and the air pump 16 is fixed to the outer wall of the aeration separation cylinder 15.

[0064] The water containing algae is pumped into the crushing box 10 through the algae pumping pipeline and enters the filter cartridge 13 for preliminary separation of algae and water. The third motor 11 drives the cutting knife 20 arranged in the crushing box 10 to cut and crush the algae in the filter cartridge 13 to ensure the separation effect from the water. The separated water enters the aeration separation cylinder 15. Under the action of the air pump 16 and the air pipe 17, the aeration head 18 produces a large number of bubbles. These bubbles can increase the oxygen content in the water on the one hand, and separate impurities in the water from the water on the other hand, so that impurity foam is formed on the surface of the water, and as the bubbles are broken, they adhere to the inner wall of the aeration separation cylinder 15. The water in the aeration separation cylinder 15 flows back to the culture pond through the leakage hole 19 at the bottom. Through such an arrangement, impurities in the water can be further separated and the oxygen content of the water can be increased.

[0065] The device of the present invention operates periodically, and after the operation is completed, the algae fragments in the filter cartridge 13 and the impurities on the inner wall of the aeration separation cartridge 15 are cleaned up.

[0066] A further optimized solution is that the algae transporting pumping pipeline includes a submersible pump 22 connected to the algae transporting hole 23, the liquid inlet end of the submersible pump 22 is connected to the algae transporting hole 23, the liquid outlet end of the submersible pump 22 is connected to the bottom end of the algae transporting branch pipe 21, the top ends of several algae transporting branch pipes 21 are connected to the same algae transporting main pipe 8, the algae transporting main pipe 8 is fixedly connected to the cross beam 9, and the liquid outlet end of the algae transporting main pipe 8 is connected and arranged on the top side of the crushing box 10.

[0067] The water containing algae at the algae transport hole 23 can be pumped into the algae transport main pipe 8 through the algae transport branch pipe 21 by the submersible pump 22, and then enters the crushing box 10 through the algae transport main pipe 8 for crushing and separation.

[0068] According to a further optimized solution, the oxygenation assembly includes a second motor 4, a fixed end of the second motor 4 is fixedly connected to the motor bracket 2, and an output shaft of the second motor 4 is connected to an impeller 5, which is used to transport the surface water of the culture pond to the bottom water.

[0069] The second motor 4 drives the impeller 5 to rotate and transports the surface water to the bottom of the breeding pond. The surface water has a high oxygen content due to contact with the air. The surface water moves to the bottom of the breeding pond, and the bottom water of the breeding pond comes to the surface of the breeding pond and contacts with the air. Through this arrangement, the oxygen content of the breeding water can be increased, and the uniformity of oxygen distribution can also be improved.

[0070] The device has a simple structure and is easy to use. It can clean the algae in the breeding pond by collecting, crushing and separating the algae from water. At the same time, the water separated from the algae returns to the breeding pond to reduce water consumption. The device can greatly help farmers to automatically remove algae, maintain the breeding environment, and reduce labor consumption through automated settings. It also has a simple structure and low cost, and is suitable for promotion and use in the field of fish breeding.
