The pesticide sprayer 30 includes a pipe, and multiple small holes are drilled in the pipe wall.

[0027] The mixed flow stirring device is sequentially provided with a mixed flow plate 4 and a bin clamping plate 40. The mixed flow plate 4 is sealedly spliced with the inner wall of the collecting tank 1 at two sides, and has a gap between the upper edge of the mixed flow plate 4 and the water surface outside the collecting tank 1, and between the lower edge of the mixed flow plate 4 and the bottom plate of the inner cavity of the collecting tank 1. The lower edge and the side edge of the bin clamping plate 40 are sealedly spliced with the inner wall of the collecting tank 1, and the upper edge of the bin clamping plate 40 is lower than the inlet bottom plate 31 and is provided with a second overflow door 41 with adjustable flow at the upper edge.

[0028] The water filtering channel 51 is provided with a water filling valve 52.

[0029] The front side plate 53 is provided between the cyanobacteria coagulation bin 7 and the algae water separation bin 5, the upper edge of the front side plate 53 is lower than the upper edge of the bin clamping plate 40, and the front side plate 53 is provided with a third overflow door 54 with adjustable flow at the upper edge.

[0030] The cyanobacteria collecting pump 70 is provided with a collecting suction port, the collecting suction port is trumpet-shaped, the collecting suction port faces upward, and the collecting suction port is lower than the upper edge of the front side plate 53. The cyanobacteria collecting pump 70 can be adjusted in height according to requirements. The cyanobacteria coagulation bin 7 is connected with the waste water accumulation bin 8, and a side plate 55 is provided between the cyanobacteria coagulation bin 7 and the waste water accumulation bin 8. The upper edge of the side plate 55 is higher than the upper edge of the front side plate 53, the lower edge of the side plate 55 is lower than the collecting suction port of the cyanobacteria collecting pump 70, and the side plate 55 is sealedly spliced with the front side plate 53 and the collecting tank 1 at two sides. The waste water accumulation bin 8 is provided with a waste water discharge pump 80 for discharging algae water in the waste water accumulation bin 8 to the algae water separation bin 5. The waste water discharge pump 80 is provided with a waste water suction port, the waste water suction port faces downward, and the waste water suction port is lower than the upper edge of the front side plate and higher than the upper edge of the collecting suction port. The water filtering channel 51 and the filtered water accumulation bin 6 are provided with a partition plate 56. The lower edge of the partition plate 56 and the bottom of the water filtering channel 51 are provided with a gap 57 for water flow.

[0031] In the embodiment, the guide rail frames 9 around the periphery are fixed and connected together by the fixed supports 93, the guide rail frames 9 are sleeved on the guide columns 90, the guide columns 90 are fixed on the underwater riverbed, and the collecting tank 1 is placed in the guide rail frames 9. Since the guide rail frames 9 are provided with tracks 91, the rollers 92 outside the collecting tank 1 can roll up and down in the tracks 91 on the guide rail frames 9. Therefore, when the collecting tank 1 encounters the rise and fall of the water level, the collecting tank 1 will move up and down along the tracks 91 by the outside rollers 92 due to the change of the buoyancy of the collecting tank 1. The collecting tank 1 can naturally rise and fall when the water level rises and falls, and the collecting tank 1 will not be drifted when encountering waves, so that the collecting tank 1 can be better kept in the best position for collecting floating algae.

[0032] The main float tanks 2 symmetrically arranged in the inner cavities at two sides of the collecting tank 1 bear the entire weight of the collecting tank, and the balance float tank 32 fills the missing buoyancy of the front end of the main float tanks 2 at two sides of the collecting tank to balance the entire device.

[0033] When in use, the water collecting tank 1 sinks to the designed water level under the joint action of the water filling valve 52 and the filtered water discharge pump 60. At this time, the algae water enters the water collecting tank through the inlet 3. The first overflow door 33 arranged on the inlet bottom plate 31 can adjust the water inflow according to the accumulation degree of the cyanobacteria on the water surface, and the medicament sprayer 30 on the first overflow door 33 is connected with the external medicament tank to uniformly spray the required medicament into the algae water flowing into the first overflow door 33 through the small holes on the pipeline. At this time, the algae water and the medicament mixture flow through the mixing plate 4 in the subsequent mixing and stirring device from top to bottom, and then roll and mix from top to bottom, which has the stirring and mixing effect of the medicament and the algae water. The medicament can fully flocculate and coagulate the floating algae, and then flow through the second overflow door 41 on the warehouse clamp plate 40 into the algae water separation warehouse 5. At this time, the second overflow door 41 on the warehouse clamp plate 40 controls the algae slurry to enter the algae water separation warehouse 5 at a set flow rate. Since the algae water separation warehouse 5 has a large enough space, the flocculated floating algae has enough time to fully coagulate and float. At this time, the algae water is blocked by the filter screen frame 50, so that a large amount of filtered water enters the filtered water channel 51, and then flows into the filtered water accumulation warehouse 6 through the gap 57 of the partition plate 56. The filtered water discharge pump 60 in the filtered water accumulation warehouse 6 continuously discharges the filtered water out of the water collecting tank 1. At the same time, the flocculated, coagulated and floating algae on the upper layer blocked by the filter screen frame 50 flows into the cyanobacteria coagulation warehouse 7 through the third overflow door 54 of the front side plate 53. The cyanobacteria collecting pump 70 sucks the floating algae from the collecting suction port and discharges it out of the water collecting tank 1. At the same time, the waste water discharge pump 80 in the waste water accumulation warehouse 8 sucks the waste water containing suspended algae from the waste water accumulation warehouse 8 through the waste water suction port and discharges it to the algae water separation warehouse 5, so that the algae water can be re-flocculated.

[0034] When it is necessary to clean and maintain the device, the water filling valve 52 is closed, and the filtered water discharge pump 60 discharges the waste water in the water collecting tank 1 out of the water collecting tank, which can improve the buoyancy of the device and make the device float.

[0035] Example 2:

[0036] The water surface cyanobacteria automatic water separation and collecting device described in this embodiment is as follows: Figures 5 to 6Different from the features described in embodiment 1, the mixed flow stirring device comprises a plurality of upper mixed flow plates 42, a plurality of lower mixed flow plates 43 and a warehouse clamping plate 40. The upper edge of the upper mixed flow plate 42 is higher than the water surface outside the collection tank 1, the lower edge is spaced apart from the bottom plate of the inner cavity of the collection tank 1, and the two sides are sealed and spliced with the inner wall of the collection tank 1. The upper edge of the lower mixed flow plate 43 is lower than the upper edge of the inlet bottom plate 13 and higher than the upper edge of the warehouse clamping plate 40, the lower edge and the two sides are sealed and spliced with the inner wall of the collection tank 1, the upper and lower rows of the plurality of upper mixed flow plates 42 and the plurality of lower mixed flow plates 43 are staggered to form a "W" shaped water channel, the warehouse clamping plate 40 is arranged at the rear of the "W" shaped water channel, the lower edge and the side edge of the warehouse clamping plate 40 are sealed and spliced with the inner wall of the collection tank 1, the upper edge is lower than the inlet bottom plate 31, and the second overflow door 41 with adjustable flow is arranged at the upper edge.

[0037] In this embodiment, the mixed flow stirring device adopts three upper mixed flow plates 42 and two lower mixed flow plates 43 arranged in upper and lower rows to form a "W" shaped water channel. After the "W" shaped water channel, the algae water and the medicine water are more fully stirred, so that more floating algae are obtained, and then the second overflow door 41 on the warehouse clamping plate 40 is passed. The flow limiting effect of the second overflow door 41 makes the algae content of the algae water higher, so as to facilitate subsequent processing. It is particularly pointed out that the number of the upper mixed flow plate 42 and the lower mixed flow plate 43 is different according to different requirements in actual use, and the number of the upper mixed flow plate 42 and the lower mixed flow plate 43 is different according to different requirements in actual use. This embodiment is only a preferred scheme, and the number of the upper mixed flow plate 42 and the lower mixed flow plate 43 is not limited.
