[0002] Cyanobacteria exhibit a seasonal outbreak pattern, sinking to the bottom and going dormant in winter, and floating to the surface to reproduce in spring. The outbreak period of cyanobacteria covers spring to autumn. If only the cyanobacteria on the water surface are controlled, they will sink to the bottom again in winter and break out again in spring of the next year. Therefore, it often takes years of continuous treatment for the cyanobacteria to significantly decrease.

[0003] The traditional treatment method is to use enclosures to restrict the spread of cyanobacteria, and then use a variety of methods for comprehensive treatment. For example: centralized treatment after salvage by a salvage ship or adding algal control reagents, etc. The traditional method can only be implemented for restriction and treatment after the outbreak of cyanobacteria, with significant lag. It cannot effectively control the source of the cyanobacteria outbreak, resulting in slow treatment effectiveness.

[0031] First Embodiment:

[0032] Figure 1 The structural schematic diagram of the offshore algal control enclosure system according to the first embodiment of the present invention application is shown. In combination with Figure 1 As shown, the present invention discloses an offshore algal control enclosure system.

[0033] The offshore algal control enclosure system includes: an enclosure part 1, an inlet buoy 2 connected to one end of the enclosure part 1, an outlet buoy 3 connected to the other end of the enclosure part 1, an extrusion mechanism 4 for extruding cyanobacteria, a pressurizing device 5 provided on the inlet buoy 2, and a chemical dosing device 6 for injecting a medium.

[0034] Among them, the positions of the inlet buoy 2 and the outlet buoy 3 are distributed in a staggered manner along the cyanobacteria flow direction, so that the enclosure part 1 is inclined to the cyanobacteria flow direction. After the cyanobacteria come into contact with the enclosure part 1, they are blocked, and the cyanobacteria gradually accumulate and flow towards the inlet buoy 2. The enclosure part 1 itself has flexibility, and the enclosure part 1 gradually bends into an arc shape, forming a collection area on the side of the enclosure part 1 close to the cyanobacteria, so that the enclosure part 1 can block more cyanobacteria.

[0035] The pressurizing device 5 pressurizes and extrudes the cyanobacteria and transports the cyanobacteria to the outlet buoy 3. The cyanobacteria are collected in the inlet buoy 2, and the pressurizing device 5 pressurizes the cyanobacteria in the inlet buoy 2. After the pressure in the inlet buoy 2 reaches 0.7 Mpa, the cyanobacteria burst. After being pressurized, the cyanobacteria flow into one end of the enclosure part 1 close to the inlet buoy 2, and the pressurizing device 5 injects gas to push the pressurized cyanobacteria to flow along the inside of the enclosure part 1 and approach the outlet buoy 3. After the pressurized cyanobacteria complete water separation in the enclosure part 1, the pressurized cyanobacteria impact on the extrusion mechanism 4.

[0036] The extrusion mechanism 4 is rotatably arranged in the outlet buoy 3. The chemical dosing device 6 is arranged on the outlet buoy 3 near the extrusion mechanism 4. After being punched, the cyanobacteria are extruded by the extrusion mechanism 4, and the cyanobacteria burst and are extruded into strips. During the extrusion process, the chemical dosing device 6 injects a medium into the extrusion mechanism 4 to facilitate the formation of the extruded cyanobacteria into strips. After the strip-shaped cyanobacteria are discharged, they sink to the bottom of the water and continuously release the medium, and the medium eliminates the cyanobacteria at the bottom of the water.

[0037] The inlet buoy 2 includes: an inlet main body 21, a pressurizing cylinder body 22 arranged in the inlet main body 21, and a lifting float bladder 23 arranged around the inlet main body 21. Among them, the pressurizing device 5 is respectively connected to the pressurizing cylinder body 22 and the lifting float bladder 23. The pressurizing cylinder body 22 is connected to the enclosure part 1.

[0038] Exemplarily, two groups of pressurized cylinders 22 are used alternately to ensure that cyanobacteria continuously enter the inlet buoy 2. The pressurized cylinder 22 includes a horizontal portion 221 and a vertical portion 222 vertically connected to the horizontal portion 221. One group of pressurized cylinders 22 is inserted and superimposed on another group of pressurized cylinders 22. The pressurized cylinders 22 always form a downward force to prevent the inlet buoy 2 from tipping due to weightlessness.

[0039] Exemplarily, the pressurized cylinder 22 is in an inverted T shape. Another group of pressurized cylinders 22 forms a structure that is vertically through, facilitating the insertion of one group of pressurized cylinders 22 from below into another group of pressurized cylinders 22 for superimposed installation.

[0040] When cyanobacteria flow into or out of the pressurized cylinder 22, the floating and sinking state of the inlet main body 21 changes accordingly. If the inlet main body 21 floats excessively and cyanobacteria cannot enter the pressurized cylinder 22, the lifting floating bladder 23 is opened to discharge the internal gas.

[0041] If the inlet main body 21 sinks excessively and the water surface submerges the inlet of the pressurized cylinder 22, and cyanobacteria also cannot enter the pressurized cylinder 22, gas is injected into the lifting floating bladder 23 through the pressurizing device 5.

[0042] Figure 2 The right view enlarged structure diagram of the inlet position of the present invention application is shown. Combining Figure 1 and Figure 2 As shown, a long strip-shaped inlet position 211 is formed on the inlet main body 21. A sector plate 212 is rotatably provided on the inlet main body 21. A first power device 213 is also provided on the inlet main body 21. Exemplarily, the first power device 213 is a micro motor. The first power device 213 drives the sector plate 212 to rotate downward, and the sector plate 212 covers the inlet position 211. The gas injected into the pressurized cylinder 22 pushes the sector plate 212 to fit against the inlet main body 21 near the inlet position 211, and cyanobacteria cannot flow into the pressurized cylinder 22 through the inlet position 211. The first power device 213 drives the sector plate 212 to rotate upward, and the sector plate 212 exposes the inlet position 211, and cyanobacteria flow into the pressurized cylinder 22 through the inlet position 211.

[0043] Exemplarily, the cross-sectional shape of the inlet main body 21 is triangular. One corner of the inlet main body 21 is connected to the enclosure portion 1. When the offshore algae control enclosure system moves, the resistance to the movement of the inlet buoy 2 is reduced through the edges and corners of the inlet main body 21. The edges and corners of the inlet main body 21 can effectively block cyanobacteria and expand the blocking range of the inlet main body 21, thereby expanding the collection area.

[0044] The enclosure portion 1 includes a plurality of pipes 11 connected to each other, floating blocks 12 are arranged between adjacent pipes 11, an enclosure cloth 13 wrapping the pipes 11, and elbow pipes 14 arranged in the floating blocks 12. Among them, the elbow pipes 14 connect adjacent pipes 11. The enclosure cloth 13 floats on the water surface to block cyanobacteria.

[0045] Exemplarily, the bent pipe 14 is a corrugated bent pipe. The floating blocks 12 are located at both ends of the bent pipe 14. The floating blocks 12 are respectively communicated with the pipe 11 and the bent pipe 14.

[0046] A plurality of pipes 11 are communicated through the bent pipe 14, so that the enclosure part 1 has flexibility, avoiding the pipes 11 being too long and prone to breakage. The floating blocks 12 form a floating support for the pipes 11 and the bent pipe 14. The floating blocks 12 limit the bending degree of the bent pipe 14. When the bent pipe 14 is bent to a preset angle, the floating blocks 12 abut against each other to limit the continuous bending of the bent pipe 14, so that the enclosure part 1 can be bent and maintained in an arc shape.

[0047] Figure 6 The cross-sectional structure diagram of the pipe in the first embodiment of the present invention application is shown. Combining Figure 1 、 Figure 2 and Figure 6 as shown, the pipe 11 includes an inner pipe 111, an outer pipe 112, a partition rib 113 and a conduit 115. The inner pipe 111 and the outer pipe 112 are coaxially arranged. The partition rib 113 divides the space between the inner pipe 111 and the outer pipe 112 into a plurality of pipe spaces 114. Exemplarily, the partition rib 113 is wavy. When the pipe 11 is stressed, the wavy partition rib 113 can form a certain amount of collapse, avoiding the conduction of stress and not causing damage to the inner pipe 111 and the outer pipe 112.

[0048] The lower end of the inner pipe 111 is communicated with the pipe space 114 below. After pressurization, the water in the cyanobacteria sinks and flows into the pipe space 114 below, and the water is then discharged through the conduit 115. One end of the conduit 115 extends into the pipe space 114 below, and the other end of the conduit 115 extends downward into the water surface. Since the height of one end of the conduit 115 is higher than the height of the other end of the conduit 115, the conduit 115 can only flow unidirectionally and will not generate backflow.

[0049] Figure 3 The structural diagram of the outlet buoy in the first embodiment of the present invention application is shown. Figure 4 The structural diagram of the extrusion disc in the first embodiment of the present invention application is shown. Figure 5 The structural diagram of the fixed disc in the first embodiment of the present invention application is shown. Combining Figures 1-6 as shown, the extrusion mechanism 4 includes: an extrusion space 41 formed in the outlet buoy 3, an extrusion disc 42 rotatably arranged in the extrusion space 41, and a fixed disc 43 fixedly arranged in the extrusion space 41. Among them, the extrusion disc 42 and the fixed disc 43 are respectively communicated with the water surface and the enclosure part 1.

[0050] The extrusion disc 42 includes a first extrusion groove 421 and a second extrusion groove 422 that are connected in sequence from top to bottom. The fixed disc 43 includes a first extrusion surface 431 and a second extrusion surface 432 that are formed by gradual transition from top to bottom. The inner surface of the first extrusion groove 421 and the first extrusion surface 431 are inclined surfaces, and an included angle is formed between the inner surface of the first extrusion groove 421 and the first extrusion surface 431. The inner surface of the second extrusion groove 422 and the second extrusion surface 432 are inclined surfaces, and the inner surface of the second extrusion groove 422 and the second extrusion surface 432 are mutually attached.

[0051] A moving groove 433 is formed from top to bottom along the first extrusion surface 431 and the second extrusion surface 432. A flow groove 434 is formed from top to bottom along the first extrusion surface 431. The flow groove 434 communicates with the moving groove 433, and the moving groove 433 on the second extrusion surface 432 gradually narrows. A collection groove 435 is formed around the transition position of the first extrusion surface 431 and the second extrusion surface 432, and the flow groove 434 communicates with the collection groove 435. The collection groove 435 communicates with the bottom of the fixed disc 43.

[0052] The upper end of the extrusion disc 42 communicates with the bending cylinder 44. The cyanobacteria in the inner blue algae of the partition part 1 are stamped at the bending part of the bending cylinder 44 and then fall and are stamped on the upper end of the fixed disc 43. After stamping, the cyanobacteria enter between the extrusion disc 42 and the fixed disc 43.

[0053] After stamping, the cyanobacteria first enter between the inner surface of the first extrusion groove 421 and the first extrusion surface 431 for extrusion. After extrusion, the cyanobacteria enter the moving groove 433 and continue to move. After extrusion, the moisture enters the flow groove 434 and continues to move. After extrusion, the cyanobacteria enter the moving groove 433 on the second extrusion surface 432, and then are discharged between the extrusion disc 42 and the fixed disc 43. After extrusion, the moisture enters the collection groove 435 and is discharged from the fixed disc 43 through a one-way valve.

[0054] A transmission member 45 is arranged around the extrusion disc 42. A second power device 32 is arranged on the outlet float 3, and a driving wheel 33 is arranged at the driving end of the second power device 32. Exemplarily, the second power device 32 is a motor. The extrusion disc 42 is driven by a transmission belt 34, and the transmission belt 34 is respectively wound around the driving wheel 33 and the transmission member 45. The second power device 32 drives the driving wheel 33 to rotate, and the driving wheel 33 drives the transmission member 45 and the extrusion disc 42 to rotate through the transmission belt 34.

[0055] The chemical adding device 6 includes a chemical adding pipe 61, a metering pump 62 and a medicine cylinder 63. The outlet of the chemical adding pipe 61 is located in the middle between adjacent moving grooves 433 on the second extrusion surface 432. The extrusion disc 42 pushes the medium into the moving groove 433. Since the moving groove 433 on the second extrusion surface 432 gradually narrows, the cyanobacteria after extrusion accumulate and wrap the medium.

[0056] After extrusion, the cyanobacteria are continuously discharged in strips. When the length of the extruded cyanobacteria is too long, the extruded cyanobacteria break and fall into the water surface. The strip-shaped extruded cyanobacteria sink to the bottom of the water and continuously release the medium, and the medium acts on the cyanobacteria at the bottom of the water. The strip-shaped extruded cyanobacteria can be entangled and hung at the bottom of the water and will not flow with the water. The strip-shaped extruded cyanobacteria can be fixed at a position at the bottom of the water and continuously eliminate the cyanobacteria.

[0057] A thruster 31 is installed at the bottom of the outlet buoy 3, and a paddle mechanism 24 is rotatably arranged at the bottom of the inlet buoy 2. When the offshore algae control enclosure system moves, the paddle mechanism 24 is parallel to the propulsion direction of the thruster 31. When the offshore algae control enclosure system stops, the paddle mechanism 24 is perpendicular to the propulsion direction of the thruster 31. The inlet buoy 2 is provided with a third power device 25. Exemplarily, the third power device 25 is a motor. The third power device 25 drives the paddle mechanism 24 to rotate.

[0058] The offshore algae control enclosure system is placed at the deployment position by a ship. According to the situation of the cyanobacteria, it is necessary to adjust the deployment state of the offshore algae control enclosure system. The thruster 31 is started to drive the outlet buoy 3 to move. The outlet buoy 3 drives the inlet buoy 2 to move by pulling the enclosure part 1. At this time, the paddle mechanism 24 is parallel to the propulsion direction of the thruster 31, and the paddle mechanism 24 will not form resistance, and the inlet buoy 2 can move smoothly. When the offshore algae control enclosure system stops, the outlet buoy 3 stops moving, but due to inertia, the enclosure part 1 drives the inlet buoy 2 to continue to move a certain distance, which will damage the deployment state of the offshore algae control enclosure system. By making the paddle mechanism 24 perpendicular to the propulsion direction of the thruster 31, the paddle mechanism 24 forms resistance in the moving direction of the offshore algae control enclosure system, and the offshore algae control enclosure system will not have a large displacement after the thruster 31 is turned off, maintaining the deployment state of the offshore algae control enclosure system.

[0059] The offshore algae control enclosure system further includes: a battery 7 and a photovoltaic panel 71 connected to the input end of the battery 7. The photovoltaic panel 71 is installed on the tops of the inlet buoy 2 and the outlet buoy 3. The battery 7 is installed inside the inlet buoy 2 and the outlet buoy 3. The output end of the battery 7 is connected to the extrusion mechanism 4, the pressurizing device 5, the chemical dosing device 6, the thruster 31 and the paddle mechanism 24.

[0060] The photovoltaic panel 71 stores energy for the battery 7, and the battery 7 supplies power to the offshore algae control enclosure system. In addition to being powered by the battery 7, the offshore algae control enclosure system also has a power supply interface for power supply through the ship power supply to ensure the long-term operation of the offshore algae control enclosure system and can cope with the large-scale sudden outbreak of cyanobacteria.

[0061] Second Embodiment:

[0062] The algae control method of the offshore algae control enclosure system includes the following steps:

[0063] Analysis steps: Determine the cyanobacteria outbreak points based on satellite image data, speculate on the cyanobacteria pre-outbreak points based on meteorological data, and infer the cyanobacteria sedimentation points based on historical gas-phase data. Determine the cyanobacteria scale data at each point based on satellite image data. Determine the deployment locations of the offshore algae control enclosure system according to the positions of each point, and determine the deployment scale of the offshore algae control enclosure system according to the cyanobacteria scale data at each point.

[0064] The analysis steps not only need to determine the current cyanobacteria outbreak points, but also need to predict the future cyanobacteria pre-outbreak points and infer the previous cyanobacteria sedimentation points. Speculate on the scale of the cyanobacteria pre-outbreak points and the cyanobacteria sedimentation points based on the scale of the current cyanobacteria outbreak points. It can be determined whether to deploy centrally or dispersedly according to the data of each point.

[0065] Centralized deployment: First, deploy the offshore algae control enclosure system at the cyanobacteria outbreak points. After the cyanobacteria at the cyanobacteria outbreak points are cleared, the offshore algae control enclosure system moves to the cyanobacteria sedimentation points.

[0066] Dispersed deployment: Deploy the offshore algae control enclosure system at the cyanobacteria outbreak points and the cyanobacteria sedimentation points respectively, and then adjust the scale of the offshore algae control enclosure system at the two points according to the cleaning situation.

[0067] Adjustment steps: The thruster 31 starts to drive the outlet buoy 3 to move. The outlet buoy 3 pulls the inlet buoy 2 to move through the enclosure part 1. At this time, the paddle mechanism 24 is parallel to the advancing direction of the thruster 31. When the outlet buoy 3 approaches the preset position, the paddle mechanism 24 is perpendicular to the advancing direction of the thruster 31 to form a resistance. The outlet buoy 3 slowly reaches the preset position under the action of the resistance, and the thruster 31 is turned off.

[0068] The outlet buoy 3 pulls the enclosure part 1 to open into an arc shape, and the offshore algae control enclosure system forms a collection area facing the cyanobacteria, and the cyanobacteria gradually accumulate in the collection area.

[0069] Pressurization steps: The cyanobacteria gradually flow into the pressurization cylinder body 22, and the pressurization device 5 gradually fills the lifting float bladder 23 with gas to maintain the floating height of the inlet main body 21, so that the cyanobacteria can continuously flow into the pressurization cylinder body 22.

[0070] After a group of pressurization cylinder bodies 22 are filled with cyanobacteria, they are closed, and another group of pressurization cylinder bodies 22 are opened to flow in cyanobacteria. The alternating pressurization of the pressurization cylinder bodies 22 realizes the continuous treatment of cyanobacteria.

[0071] The pressurization device 5 fills the pressurization cylinder body 22 with gas for pressurization, and the pressure in the pressurization cylinder body 22 reaches 0.7 Mpa. After pressurization, the algal cells in the cyanobacteria rupture.

[0072] Stamping step: After pressurizing the inside of the pressurized cylinder 22, the cyanobacteria enter the enclosure part 1, and the lifting float bladder 23 gradually discharges gas. The pressurizing device 5 fills the pipeline 11 with high-pressure gas. After pressurization, the cyanobacteria flow rapidly in the enclosure part 1. Part of them are discharged from the pipeline 11, and the other part impacts on the extrusion mechanism 4.

[0073] After pressurization, the cyanobacteria flow from the pressurized cylinder 22 into the pipeline 11. Due to the relatively high pressure inside the pressurized cylinder 22, the pressurized cyanobacteria flow through the enclosure part 1 at a relatively fast flow rate and flow into the outlet buoy 3.

[0074] When the length of the enclosure part 1 is too long, or when the number of elbow pipes 14 in the enclosure part 1 is large, the flow rate of the pressurized cyanobacteria will slow down during the flowing process. By injecting gas into the pipeline 11 through the pressurizing device 5, the flow rate of the pressurized cyanobacteria is ensured, so that the water in the pressurized cyanobacteria can flow into the pipe space 114 in a fast-flowing state and then be discharged through the conduit 115, avoiding the discharge of unbroken algal cells in the pressurized cyanobacteria.

[0075] Extrusion step: The extrusion disk 42 rotates, and the dosing device 6 injects a medium into the cyanobacteria after stamping. The cyanobacteria after stamping are extruded by the extrusion disk 42 and the fixed disk 43 to form strips and sink to the bottom of the water.

[0076] The extrusion disk 42 rotates. The cyanobacteria after stamping are first extruded by the first extrusion groove 421 and the first extrusion surface 431. After extrusion, the cyanobacteria enter the moving groove 433, and the water after extrusion enters the flowing groove 434. The water after extrusion is concentrated in the collecting groove 435 and then discharged. The cyanobacteria after stamping are then extruded by the second extrusion groove 422 and the second extrusion surface 432, and the cyanobacteria after extrusion enter the moving groove 433.

[0077] The dosing device 6 injects the medium. The extrusion disk 42 pushes the medium into the moving groove 433. The moving groove 433 gradually narrows, and the cyanobacteria after extrusion accumulate to wrap the medium. The cyanobacteria after extrusion form strips and are discharged. The strip-shaped cyanobacteria after extrusion sink to the bottom of the water. Due to the relatively long length of the cyanobacteria after extrusion, they will be entangled with the sundries at the bottom of the water. With the soaking of water, the medium in the cyanobacteria after extrusion can be continuously released, and the medium acts on the cyanobacteria at the bottom of the water for elimination. This avoids the floating of cyanobacteria and the large-scale spread of cyanobacteria.

[0078] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0079] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
