[0052] Embodiment 3

[0053] With reference to Figures 1-16 The difference between the embodiment and embodiment 1 is that the water inlet end of the blue-green algae pumping pump 3 is connected with a hose 301, the lifting platform 4 is provided with a filter mesh hole 406, and the end of the hose 301 away from the blue-green algae pumping pump 3 extends to the lower side of the lifting platform 4 and communicates with the filter mesh hole 406.

[0054] The blue-green algae pumping pump 3 can pump the algae water above the lifting platform 4, and the algae water can be filtered through the filter mesh hole 406.

[0055] The second rotary motor 407 is fixedly connected with a first cleaner 408 through a support above the lifting platform 4, the first cleaner 408 corresponds to the position of the filter mesh hole 406, and the first cleaner 408 is in contact with the top end of the lifting platform 4.

[0056] The second rotary motor 407 can drive the first cleaner 408 to rotate relative to the lifting platform 4, so that the impurities clogging the top end of the filter mesh hole 406 can be scraped off, the purpose of automatically cleaning the impurities is achieved, and the pumping efficiency is improved.

[0057] Two sides of the lifting platform 4 are hinged with the carrying ship 1 through two parallel connecting rods 401, a strip-shaped sliding opening 402 is formed on the upper connecting rod 401, an electric hoist 403 is fixed above the lifting platform 4 through a support, a hook 404 is connected to the output end of the electric hoist 403, a hanging ring 405 is movably installed in the strip-shaped sliding opening 402, the hanging ring 405 is hung on the hook 404, the lifting platform 4 can be lifted by driving the hook 404 to move up and down through the electric hoist 403, and the parallelogram connecting rod mechanism between the two sides of the lifting platform 4 and the carrying ship 1 can ensure that the lifting platform 4 remains horizontal during lifting. After a period of pumping, the concentration of algae water at a certain depth will decrease sharply, resulting in empty pumping. At this time, the height of the lifting platform 4 can be changed to pump algae water at different depths, thereby improving the pumping efficiency.

[0058] Embodiment 4

[0059] With reference to Figures 1-16 The difference between this embodiment and embodiment 3 is that the two sides of the lifting platform 4 are connected with cyanobacteria enclosures 501, the cyanobacteria enclosures 501 are floating net structures, and the cyanobacteria enclosures 501 are moved by the remote control surrounding ship 5. The cyanobacteria enclosures 501 can surround the cyanobacteria in a smaller range, so as to achieve the effect of enriching the concentration of algae water, and then concentrate pumping, which can effectively improve the efficiency of pumping cyanobacteria.

[0060] Embodiment 5

[0061] With reference to Figures 1-16 The difference between this embodiment and embodiment 1 is that the cyanobacteria scraping mechanism 7 includes two parallel driving shafts 701, one of which is driven to rotate by a third rotary motor 702, and the two ends of the driving shaft 701 are provided with synchronous wheels 703. A second synchronous belt 704 is installed between the outer sides of the two synchronous wheels 703 on the same side, and a plurality of scrapers 9 are fixed between the two second synchronous belts 704, and the scrapers 9 are equally distributed on the second synchronous belt 704.

[0062] The third rotary motor 702 can drive the second synchronous belt 704 to move in a cycle, thereby driving the scraper 9 to move in a cycle. When the scraper 9 faces downward, the lower edge of the scraper 9 is immersed in the water, so that the cyanobacteria floating on the water surface can be scraped towards the algae storage chamber 213, and the cyanobacteria can be continuously scraped.

[0063] Embodiment 6

[0064] With reference to Figures 1-16The difference between the embodiment and embodiment 5 is that the scraper 9 comprises a fixed part 901 and a rotating part 902, and an automatic switch is connected to the mounting rotating shaft of the rotating part 902. When the scraper 9 is downward, the rotating part 902 is switched to a vertical state, and when the scraper 9 is upward, the rotating part 902 is switched to a horizontal state. Because the scraper 9 has the function of automatic bending, when the scraper 9 is operated to the upward state, on the one hand, the height is lower and does not protrude to the outside of the air flotation separation tank 201, and the occupied space is lower, and on the other hand, the inside of the air flotation separation tank 201 is located directly above the algae scraping mechanism 7, and a second cleaner 911 is fixed thereon. When the scraper 9 is upward and moves, it can pass below the second cleaner 911, so that the surface of the scraper 9 can be automatically cleaned by the second cleaner 911, the residual blue algae on the surface of the scraper 9 is scraped off, and the residual blue algae is prevented from being brought back into the water again.

[0065] In order to achieve the purpose of automatically switching two states, the automatic switch comprises a sleeve 909 fixed to the mounting rotating shaft of the rotating part 902, a helical limiting groove 903 is formed on the outer side of the sleeve 909, an elastic telescopic rotating shaft 904 is elastically and movably mounted at one end of the sleeve 909 away from the rotating part 902, a hemispherical trigger 905 is fixed at one end of the telescopic rotating shaft 904 away from the sleeve 909, a limiting guide rod 906 is fixed at the side of the hemispherical trigger 905 close to the fixed part 901, a limiting rod 907 is fixed at the side of the limiting guide rod 906 close to the sleeve 909, one end of the limiting rod 907 extends into the helical limiting groove 903, a limiting slide rail 908 is fixed on the fixed part 901, and the limiting slide rail 908 and the limiting guide rod 906 are horizontally movably matched, and a pushing assembly 910 is fixed on the inner wall of both sides of the air flotation separation tank 201, and the pushing assembly 910 has a U-shaped structure.

[0066] When the scraper 9 is operated to the upward state, the pushing assembly 910 is not in contact with the hemispherical trigger 905, at this time, the telescopic rotating shaft 904 is pushed away due to the action of the spring in the sleeve 909, and the rotating part 902 is in a Figure 16 state, and this state can keep the rotating part 902 rotating to the horizontal state due to the elastic force of the spring. When the scraper 9 is operated to the downward state, the rotating part 902 is in a Figure 15 state, at this time, the telescopic rotating shaft 904 moves towards the sleeve 909 due to the extrusion of the pushing assembly 910 to the hemispherical trigger 905, the hemispherical trigger 905 cannot rotate relative to the fixed part 901 due to the limiting action of the limiting slide rail 908, and one end of the limiting rod 907 extends into the helical limiting groove 903, so that the limiting rod 907 can push the sleeve 909 to rotate relative to the fixed part 901 when moving horizontally, and then drive the rotating part 902 to rotate to the vertical state, so that the algae can be scraped, and the purpose of automatically switching the state is achieved.
