adjusting the height of the upright post, and adjusting the relative position of the sealing plate and the water surface at the lowest end and the topmost end by adjusting the depth of the upright post inserted into the water bottom soil layer, so that the bottom edge of the sealing plate is positioned below the water surface at the lowest position and above the water surface at the highest position; when the sealing plate is at the highest position, the bottom of the sealing plate is supported by a positioning pin to realize limiting; when the positioning pin is pulled out, the sealing plate falls freely under the action of gravity and falls above the limiting boss, and the sealing plate is at the lowest position; meanwhile, when the height of the upright post is adjusted, the bottom edge of the roller shutter is positioned below the water surface when the roller shutter arranged on the movable floating platform is hung on the hook hole on the upright post through the hook;
step three: the medicament dropping pipe is detachably arranged below the beam close to the movable floating platform, the medicament storage box is detachably arranged above the beam close to the movable floating platform, and the medicament dropping pipe is communicated with the medicament storage box through a medicament supply pipe;
step four: an operator lifts the sealing plate to enable the whole sealing plate to be located at the highest position in the step two, and the sealing plate is located by inserting a locating pin; then loosening the plastic handle screw to enable the sleeve to slide upwards on the sliding rod, manually lifting the flat funnel-shaped collecting port to enable the whole collecting port to be located above the water surface, and tightly screwing the plastic handle screw to enable the end part of the plastic handle screw to abut against the sliding rod to achieve positioning; then, a roller shutter arranged on the movable floating platform is connected to the upright post through a hook, the upright post is provided with a hook hole, the movable floating platform is driven to leave the assembled portal frame by driving a propeller, a switch valve arranged on the pesticide supply pipe is opened at the same time, so that a flocculating agent can drip in the pesticide dripping hole, and a diving aerator is opened at the same time, so that algae flocs in water float upwards and react with the flocculating agent; in the driving process, the winding drum rotates to release the roller shutter, so that the area of a water area in the instant opening and closing reciprocating water inlet type telescopic enclosure is increased, a telescopic enclosure structure is gradually formed, after the roller shutter is completely released, the switch valve is closed, the dripping of liquid medicine is stopped, and the positioning pin is pulled down to enable the sealing plate to fall to the lowest position; the water in the area enclosed by the sealing plate, the platform and the rolling curtains on the two sides enters from the portal frame and is mixed with the flocculating agent, and the flocculating agent reacts with the algae floc to generate algae slurry which floats on the water surface;
step five: after the flocculating agent and the algae flocs fully react, an operator loosens the plastic handle screw to enable the sleeve to slide downwards on the sliding rod, the height of the flat funnel-shaped collecting opening is manually reduced to enable the upper edge of the opening of the flat funnel-shaped collecting opening to be positioned above the water surface and the lower edge of the opening to be positioned below the water surface, and then the end part of the plastic handle screw is abutted against the sliding rod to realize positioning by screwing the plastic handle screw; then the platform moves towards the assembled portal frame through the driving propeller, the winding handle is manually rotated to drive the winding drum to rotate, the winding curtain is wound, the algae slurry floating on the water surface is collected into the algae slurry storage tank through the flat funnel-shaped collection port to be stored, when the platform moves to the initial position, single operation of opening and closing the enclosure is completed, the step four-step five is repeated, and repeated fixed position operation is realized.
10. The method as claimed in claim 9, wherein the algae slurry storage tank is provided with a discharge port, the discharge port is provided with a discharge valve, when the algae slurry storage tank is full, the discharge valve is connected through a pipeline, the discharge valve is opened, and the algae slurry in the algae slurry storage tank is discharged by using a pumping device.
