Description

Technical Field

[0001] The present invention relates to the technical field of water body treatment, and particularly to a device and a method for treating cyanobacteria by using the aquatic plant water hyacinth. Background Art

[0002] The overgrowth of cyanobacteria not only affects water quality, but may also damage the aquatic ecosystem, and even produce toxic substances, posing a threat to human health. Water hyacinth, as an aquatic plant with rapid growth and strong reproductive ability, has well-developed roots and can effectively adsorb nutrients and harmful substances in water, including cyanobacteria. Through specific devices, such as water hyacinth enclosure devices, water hyacinths can be planted in waters polluted by cyanobacteria to purify water quality by using their biological characteristics.

[0003] After retrieval, the invention patent with the Chinese patent number CN111333232B discloses a device for treating lake cyanobacteria. Compared with the prior art, this invention patent with the Chinese patent number CN111333232B continuously retrieves cyanobacteria through a lifting conveyor belt, which can avoid the situation that cyanobacteria adhere to the lifting conveyor belt and are re-introduced into the lake, resulting in low efficiency. It can filter out the excess water on the retrieved cyanobacteria, eliminating the need for manual salvage operations, greatly reducing the labor intensity, reducing labor costs, saving time and effort. It can also continuously drive the lake water to flow, increasing the oxygen content in the lake water, which is beneficial to the treatment of cyanobacteria. It can also spray algicides simultaneously to achieve the treatment of cyanobacteria, including algae removal and algae inhibition.

[0004] However, in the actual use process of the above device, although it shows significant advantages in installation and fixation, simplicity of operation, and salvage efficiency, continuously retrieving seaweed will, to a certain extent, limit the diversity of its ecological treatment, and thus limit the ability of the biological self-recovery in the natural ecosystem, which restricts the diversity of its ecological treatment to a certain extent, thereby limiting the diversity of aquatic organisms. Moreover, when the above device treats cyanobacteria, it uses horizontal convex strips to block cyanobacteria, and the device needs to move continuously to gather cyanobacteria. For cyanobacteria distributed over a large area, the device needs to cover the entire lake for movement, which will greatly extend the treatment cycle and reduce the treatment efficiency. Therefore, it is necessary to propose a device and a method for treating cyanobacteria by using the aquatic plant water hyacinth. Summary of the Invention

[0005] The object of the present invention is to solve the problems existing in the prior art. By continuously fishing for seaweed, it will limit the diversity of its ecological governance to a certain extent, and further limit the ability to utilize the self - recovery ability of organisms in the natural ecosystem. This limits the diversity of its ecological governance to a certain extent. During the governance, the device needs to move continuously to achieve the aggregation of cyanobacteria. For cyanobacteria distributed over a large area, the equipment needs to cover the entire lake and move, which will greatly extend the governance cycle and reduce the governance efficiency. The present invention proposes a device and method for treating cyanobacteria by using the aquatic plant water hyacinth.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A device for treating cyanobacteria by using the aquatic plant water hyacinth, comprising a floating plate and a first fixing plate. A first servo - motor is movably connected to the outside of the floating plate. A cross - plate is fixedly connected to the outside of the first servo - motor. A water - hyacinth dragging assembly is jointly arranged on the floating plate, the first servo - motor and the cross - plate. The water - hyacinth dragging assembly includes a first dragging rope and a baffle movably connected to the floating plate, a first gear disk, a first wire winder and a threaded disk movably connected to the first servo - motor, and a second gear disk and a second wire winder movably connected to the cross - plate. The start of the first servo - motor will drive the first gear disk and the second gear disk to rotate. The simultaneous rotation of the first gear disk and the second gear disk will pull the first dragging rope and wind the first dragging rope around the outside of the first wire winder and the second wire winder. The movement of the first dragging rope will drive the baffle to move horizontally along the floating plate. The movement of the baffle will drag the water hyacinths inside the floating plate. The rotation of the threaded disk will extrude the excess water hyacinths.

[0008] A cyanobacteria aggregation assembly is jointly arranged on the floating plate and the first fixing plate. The cyanobacteria aggregation assembly includes a second dragging rope, a driving shaft and a first water - deflecting plate movably connected to the floating plate, a second servo - motor, a second water - deflecting plate, a motor and a sweeping propeller movably connected to the first fixing plate. The movement of the baffle will drag the second dragging rope horizontally. The second dragging rope is wound around the outside of the driving shaft. Due to the action of the baffle, the second dragging rope will cause the driving shaft to rotate. The rotation of the driving shaft will drive the first water - deflecting plate to rotate. The rotation of the driving shaft will drive the driven shaft to rotate. The rotation of the driven shaft will drive the second water - deflecting plate to rotate. The rotation of the first water - deflecting plate and the second water - deflecting plate will aggregate the external cyanobacteria to the upper part of the floating plate. The rotation of the sweeping propeller will remove the floating substances on the upper part of the cyanobacteria.

[0009] The above - mentioned technical solution further includes:

[0010] Multiple sets of sliding grooves are formed on the inner side of the floating board. The multiple sets of sliding grooves are linearly and evenly distributed along the floating board. One side of the floating board close to the first servo motor is fixedly connected with a first L-shaped block. The end of the first L-shaped block away from the floating board is fixedly connected to the first servo motor. The function of the sliding groove is to enable the first drag rope to slide inside the sliding groove, and the function of the first L-shaped block is to connect the floating board and the first servo motor, thereby ensuring the stability of the first servo motor.

[0011] The end of the output shaft of the first servo motor is fixedly connected to the first gear disk. The end of the first gear disk away from the first servo motor is fixedly connected to the first wire reel. The outside of the first wire reel is fixedly connected to the first drag rope. When the first servo motor starts, the rotation of the first servo motor can drive the first gear disk and the first wire reel to rotate, and the rotation of the first wire reel can wind the first drag rope around the outside of the first wire reel.

[0012] One side of the cross board close to the first gear disk is rotatably connected to multiple rotating shafts. The multiple rotating shafts are linearly and evenly distributed along the cross board. The function of the cross board is to connect the first servo motor and the rotating shafts, and the rotating shafts can rotate outside the cross board.

[0013] The end of the rotating shaft away from the cross board is fixedly connected to the second gear disk. The second gear disk meshes with the first gear disk. The rotation of the first gear disk can drive the second gear disk to rotate. One side of the second gear disk away from the rotating shaft is fixedly connected to the second wire reel. The outside of the second wire reel is fixedly connected to the first drag rope. The rotation of the second wire reel can also wind the first drag rope around the outside of the second wire reel. Threaded disks are fixedly connected to the ends of the second wire reel and the first wire reel away from the cross board. The rotation of the threaded disks can clean the water hyacinths.

[0014] The inside of the sliding groove is slidably connected to a baffle. One side of the baffle close to the first servo motor is fixedly connected to the first drag rope. One side of the baffle away from the first servo motor is fixedly connected to the second drag rope. The movement of the baffle will drag the second drag rope.

[0015] Symmetrically fixed connections are made at one end of the floating board away from the threaded disk with connecting plates. The two connecting plates are jointly rotatably connected to the driving shaft. The end of the second drag rope away from the baffle is fixedly connected to the driving shaft. Multiple first water deflecting plates are fixedly connected to the outside of the driving shaft. Due to the effect of the baffle, the second drag rope will gradually disengage from the outside of the driving shaft. At this time, the driving shaft will rotate, and the rotation of the driving shaft will drive the first water deflecting plates to rotate.

[0016] Both ends of the driving shaft are fixedly connected with first bevel gears. Symmetrically and fixedly connected to the outside of the floating plate are a first fixing plate and a second fixing plate. Between the first fixing plate and the second fixing plate, they are rotatably connected to the driven shaft. One end of the driven shaft close to the first bevel gear is fixedly connected with a second bevel gear. The second bevel gear meshes with the first bevel gear. The rotation of the first bevel gear will drive the second bevel gear to rotate, and the rotation of the second bevel gear will drive the driven shaft to rotate. The rotation of the driving shaft will drive the driven shafts on both sides to rotate simultaneously, and the rotation of the driven shafts will drive multiple second water deflecting plates to rotate simultaneously.

[0017] On the side of the first fixing plate away from the second fixing plate, a second L-shaped block is fixedly connected. Between the upper part of the second L-shaped block and the second servo motor, they are fixedly connected. Between the end of the output shaft of the second servo motor and the driven shaft, they are fixedly connected. Between the outside of the driven shaft and multiple second water deflecting plates, they are fixedly connected. On the side of the first fixing plate away from the second fixing plate and the motor, they are fixedly connected. Between the end of the output shaft of the motor and the cleaning propeller, they are fixedly connected. Between the end of the cleaning propeller away from the motor and the second fixing plate, they are rotatably connected. The rotation of the driven shaft will drive multiple second water deflecting plates to rotate simultaneously. The rotation of the second water deflecting plates can make the blue-green algae on both sides of the floating plate approach the floating plate.

[0018] A method for treating blue-green algae using the aquatic plant water hyacinth includes the following steps:

[0019] S1: First, the water hyacinths need to be placed inside the sliding grooves in sequence, so that the water hyacinths are linearly and evenly arranged along the floating plate. The water hyacinths are in contact with the water layer, and the roots of the water hyacinths are used to treat the blue-green algae. Start the first servo motor. The start of the first servo motor will drive the first toothed disc to rotate. Because the first toothed disc meshes with the second toothed disc, the rotation of the first toothed disc will drive the second toothed disc to rotate. The simultaneous rotation of the sliding grooves and the second toothed disc will cause the first drag rope to contract. The contraction of the first drag rope will drag the baffle.

[0020] S2: The movement of the baffle will drag the second drag rope. The contraction of the second drag rope will drive the driving shaft to rotate. The rotation of the driving shaft will drive multiple first water deflecting plates to rotate. The rotation of the first water deflecting plates will make the external blue-green algae approach one side of the floating plate.

[0021] S3: The rotation of the driving shaft will drive the driven shafts on both sides to rotate simultaneously. The rotation of the driven shafts will drive multiple second water deflecting plates to rotate simultaneously. The rotation of the second water deflecting plates can make the blue-green algae on both sides of the floating plate approach the floating plate. When the second servo motor is started, the second servo motor can drive the driving shaft to rotate, wind the second drag rope around the outside of the driving shaft, and make the baffle return to the initial position. The rotation of the cleaning propeller will remove the floating objects on the upper part of the blue-green algae.

[0022] The present invention has the following beneficial effects:

[0023] 1. In the present invention, by setting up the water hyacinth dragging component, the simultaneous rotation of the first gear disk and the second gear disk will pull the first dragging rope and cause the first dragging rope to wind around the outer sides of the first wire reel and the second wire reel. The movement of the first dragging rope will drive the baffle plate to move horizontally along the floating plate, and the movement of the baffle plate will drag the water hyacinths inside the floating plate. The dragging can make the distribution of water hyacinths more reasonable, so as to be able to inhibit blue-green algae through the roots of water hyacinths, thereby enabling the self-recovery ability of aquatic organisms in the natural ecosystem and protecting the biodiversity of aquatic organisms.

[0024] 2. In the present invention, by setting up the blue-green algae aggregation component, further, the rotation of the driving shaft will drive the rotation of the first water deflecting plate, the rotation of the driving shaft will drive the rotation of the driven shaft, and the rotation of the driven shaft will drive the rotation of the second water deflecting plate. The rotation of the first water deflecting plate and the second water deflecting plate will aggregate the external blue-green algae to the upper part of the floating plate, thus avoiding the need to continuously move to aggregate the blue-green algae. This will reduce the treatment cycle of blue-green algae and improve the treatment efficiency of blue-green algae. BRIEF DESCRIPTION OF THE DRAWINGS

A first servo motor 4 is movably connected to the outside of the floating board 1. A horizontal board 9 is fixedly connected to the outside of the first servo motor 4. A water hyacinth dragging assembly is jointly arranged on the floating board 1, the first servo motor 4 and the horizontal board 9.

The start of the first servo motor 4 will drive the first toothed disc 5 and the second toothed disc 11 to rotate. The simultaneous rotation of the first toothed disc 5 and the second toothed disc 11 will pull the first dragging rope 7 and wind the first dragging rope 7 around the outside of the first wire reel 6 and the second wire reel 12. The movement of the first dragging rope 7 will drive the baffle 8 to move horizontally along the floating board 1. The movement of the baffle 8 will drag the water hyacinth inside the floating board 1. The rotation of the threaded disc 13 will squeeze the excess water hyacinth;

[0036] A cyanobacteria aggregation component is jointly arranged on the floating board 1 and the first fixed board 21. The cyanobacteria aggregation component includes a second drag rope 14, a driving shaft 16, and a first water deflecting board 17 that are movably connected to the floating board 1, and a second servo motor 23, a second water deflecting board 24, a motor 26, and a sweeping propeller 27 that are movably connected to the first fixed board 21. The movement of the baffle 8 will drag the second drag rope 14 in the horizontal direction. The second drag rope 14 is wound around the outside of the driving shaft 16. Due to the effect of the baffle 8, the second drag rope 14 will cause the driving shaft 16 to rotate. The rotation of the driving shaft 16 will drive the first water deflecting board 17 to rotate. The rotation of the driving shaft 16 will drive the driven shaft 20 to rotate. The rotation of the driven shaft 20 will drive the second water deflecting board 24 to rotate. The rotation of the first water deflecting board 17 and the second water deflecting board 24 will aggregate external cyanobacteria to the upper part of the floating board 1. The rotation of the sweeping propeller 27 will remove the floating objects on the upper part of the cyanobacteria.

[0037] Multiple sliding grooves 2 are formed inside the floating board 1. The multiple sliding grooves 2 are linearly and evenly distributed along the floating board 1. One side of the floating board 1 close to the first servo motor 4 is fixedly connected with a first L-shaped block 3. One end of the first L-shaped block 3 away from the floating board 1 is fixedly connected to the first servo motor 4. The function of the sliding groove 2 is to enable the first drag rope 7 to slide inside the sliding groove 2. The function of the first L-shaped block 3 is to connect the floating board 1 and the first servo motor 4, thereby ensuring the stability of the first servo motor 4.

[0038] The end of the output shaft of the first servo motor 4 is fixedly connected to the first gear disk 5. One end of the first gear disk 5 away from the first servo motor 4 is fixedly connected to the first wire reel 6. The outside of the first wire reel 6 is fixedly connected to the first drag rope 7. When the first servo motor 4 is started, the rotation of the first servo motor 4 can drive the first gear disk 5 and the first wire reel 6 to rotate. The rotation of the first wire reel 6 can wind the first drag rope 7 around the outside of the first wire reel 6.

[0039] One side of the cross board 9 close to the first gear disk 5 is rotatably connected to multiple rotating shafts 10. The multiple rotating shafts 10 are linearly and evenly distributed along the cross board 9. The function of the cross board 9 is to connect the first servo motor 4 and the rotating shafts 10. The rotating shafts 10 can rotate outside the cross board 9.

[0040] One end of the rotating shaft 10 away from the cross plate 9 is fixedly connected to the second gear disc 11. The second gear disc 11 meshes with the first gear disc 5. The rotation of the first gear disc 5 can drive the rotation of the second gear disc 11. One side of the second gear disc 11 away from the rotating shaft 10 is fixedly connected to the second wire reel 12. The outside of the second wire reel 12 is fixedly connected to the first drag rope 7. The rotation of the second wire reel 12 can also wind the first drag rope 7 around the outside of the second wire reel 12. Threaded discs 13 are fixedly connected to one end of both the second wire reel 12 and the first wire reel 6 away from the cross plate 9. The rotation of the threaded discs 13 can clean the water hyacinths.

[0041] The inside of the sliding groove 2 is slidably connected to the baffle 8. One side of the baffle 8 close to the first servo motor 4 is fixedly connected to the first drag rope 7. One side of the baffle 8 away from the first servo motor 4 is fixedly connected to the second drag rope 14. The movement of the baffle 8 will drag the second drag rope 14.

[0042] In this embodiment, the simultaneous rotation of the first gear disc 5 and the second gear disc 11 will pull the first drag rope 7 and wind the first drag rope 7 around the outside of the first wire reel 6 and the second wire reel 12. The movement of the first drag rope 7 will drive the baffle 8 to move horizontally along the floating plate 1. The movement of the baffle 8 will drag the water hyacinths inside the floating plate 1. The dragging can make the distribution of the water hyacinths more reasonable. The specific implementation method is as follows: The function of the floating plate 1 is to provide the required buoyancy for the device. The function of the first L-shaped block 3 is to connect the floating plate 1 and the first servo motor 4. When it is necessary to drag the water hyacinths, start the first servo motor 4. When the end of the output shaft of the first servo motor 4 rotates, it will drive the first gear disc 5 to rotate. The rotation of the first gear disc 5 will drive the first wire reel 6 to rotate. The rotation of the first wire reel 6 can wind the first drag rope 7 around the outside of the first wire reel 6. Because the first gear disc 5 and the second gear disc 11 mesh with each other, the rotation of the first gear disc 5 will drive the second gear disc 11 to rotate. The simultaneous rotation of the sliding groove 2 and the second gear disc 11 will cause the first drag rope 7 to contract. The contraction of the first drag rope 7 will drag the baffle 8. The baffle 8 will slide inside the sliding groove 2. While the baffle 8 slides, it will squeeze the water hyacinths, causing the water hyacinths to continuously move towards the side close to the threaded disc 13, so that the number of water hyacinths gradually decreases. The movement of the baffle 8 will drag the water hyacinths inside the floating plate 1. The dragging can make the distribution of the water hyacinths more reasonable, so as to inhibit the blue-green algae through the roots of the water hyacinths, and thus realize the self-recovery ability of organisms in the natural ecosystem.

The movement of the baffle 8 drags the second drag rope 14, and the contraction of the second drag rope 14 drives the rotation of the driving shaft 16. The rotation of the driving shaft 16 drives the rotation of a plurality of first water deflecting plates 17. The rotation of the first water deflecting plate 17 makes the external blue-green algae approach one side of the floating plate 1, realizing continuous treatment of blue-green algae. The rotation of the driving shaft 16 drives the rotation of the first bevel gear 18.
