Description

Technical Field

[0001] This invention relates to the fields of river and lake ecological restoration and water landscape, and in particular to a device and method for controlling and removing water hyacinth. Background Technology

[0002] Currently, the management and maintenance of lakes, wetlands, and landscape water bodies commonly encounter problems such as the proliferation of Spirogyra (green algae). Especially in early spring and early autumn when the temperature and sunlight are suitable, large areas of Spirogyra (green algae) bloom in water bodies with high transparency, forming a cover on the water surface. While affecting the sensory experience of the water body, it also blocks underwater sunlight, consumes dissolved oxygen in the water, seriously affects the normal growth of submerged plants and aquatic animals, and causes certain damage to the aquatic ecosystem.

[0003] Spirogyra (green algae) belongs to the class Zygophyllaceae, family Spirogyrae, and genus Spirogyra. It is a multicellular filamentous structure with ribbon-like chloroplasts, including filamentous algae, filamentous algae, and hydrophoretic algae. Spirogyra (green algae) reproduces through two main methods: vegetative propagation and sexual reproduction. During vegetative propagation, the filamentous body breaks into several short filaments due to mechanical damage or other reasons. Each short filament then grows into a long filamentous body through cell division. Based on the biological characteristics and outbreak patterns of Spirogyra (green algae), the conditions for its explosive growth include suitable water temperature, sufficient light, and still or slow-moving water with high organic matter content. Shallow water areas with high transparency, especially those less than 1 meter in depth, are high-incidence areas for Spirogyra (green algae).

[0004] Current control techniques for Spirogyra (green algae) are relatively limited, mainly including physical removal, chemical extermination, and biological control. Physical removal primarily relies on manual or mechanical methods, while common chemical agents for killing Spirogyra include copper sulfate, bleach, and triphenyltin acetate. However, due to the fragmentation and reproductive characteristics of Spirogyra, existing removal techniques are largely ineffective. Manual removal is costly in terms of manpower and resources, and chemical agents are avoided in most natural water bodies due to their potential ecological and environmental risks.

[0005] Based on this, the present invention designs a device and operating method for preventing and harvesting Spirogyra to solve the above problems. Summary of the Invention

[0006] Technical problems to be solved:

[0032] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0033] This invention provides a device for controlling and harvesting Spirogyra. Please refer to [link / reference]. Figures 1-7It includes a retrieval and traction collection device 1, a retrieval rope 2, and a substrate 4. The retrieval rope 2 is installed on the retrieval and traction collection device 1. Several substrates 4 are evenly connected to the retrieval rope 2. The several substrates 4 are evenly spaced along the length of the retrieval rope 2. The retrieval and traction collection device 1 drives the substrates 4 to move repeatedly between the water and the shore through the retrieval rope 2 to improve the retrieval efficiency of Spirogyra. Each substrate 4 is connected to the retrieval rope 2 through a connecting device 3.

[0034] Through the above technical solution, the attachment carrier 4 in this invention is connected to the salvage rope 2 via the connecting device 3, rather than being directly tied to the salvage rope 2, which facilitates the subsequent cleaning and replacement of the attachment carrier 4; the salvage traction and collection device 1 drives the attachment carrier 4 to move repeatedly between the water and the shore via the salvage rope 2, which can be operated on the shore, reducing the workload of water operations, not only reducing the safety risks of water operations, but also eliminating the need for manual towing, saving time and improving work efficiency; the use of a purely physical salvage method avoids the pollution to the environment caused by the use of chemical agents.

[0035] In some examples, refer to Figure 1-7 As shown, the attachment carrier 4 is formed by winding fibrous material, with a rough surface and an irregular three-dimensional shape. The attachment carrier 4 can float on the water surface.

[0036] Through the above technical solution, since the attachment carrier 4 is formed by winding fibrous material, it can float on the water surface. In addition, its surface is rough and irregular, which makes it easy for water hyacinth to adhere to the surface of the attachment carrier 4. Moreover, the fibrous material has a long lifespan and is not easily corroded by water, thus extending the service life of the attachment carrier 4.

[0037] In some examples, refer to Figure 1-7 As shown, the salvage and traction collection device 1 has two sets, each set of which is connected to the salvage rope 2. In other words, the two sets of salvage and traction collection devices 1 are connected by a salvage rope 2, on which several attachment carriers 4 are connected. Each set of salvage and traction collection devices 1 includes a rotating wheel 11, a rotating shaft 12, a support 13, and a turntable 14. The rotating wheel 11 is mounted on the rotating shaft 12 and is used to raise and lower the salvage rope 2. The rotating shaft 12 is rotatably connected to the support 13 through bearings and is used to drive the rotating wheel 11 to raise and lower the salvage rope 2. The turntable 14 is mounted on either end of the rotating shaft 12 and is used to drive the rotating shaft 12. The salvage rope 2 is cyclically raised and lowered between the two rotating wheels 11 to drive the attachment carriers 4 to move repeatedly between the water and the shore, thereby improving the salvage efficiency of Spirogyra.

[0038] Through the above technical solution, the two sets of salvage and traction collection devices 1 in this invention drive the attachment carrier 4 to move repeatedly between the water and the shore via the salvage rope 2, so that the attachment carrier 4 with sponge attached can be cleaned on both sides of the water, without the need for manual deployment of salvage rope 2 and attachment carrier 4 on the opposite bank, thus improving salvage efficiency; multiple sets of salvage and traction collection devices 1 and salvage rope 2 can be deployed to prevent large-scale sponge outbreaks in advance, while also improving salvage efficiency; by rotating the turntable 14, the rotating shaft 12 and the rotating wheel 11 can be rotated to drive the release and retraction of the salvage rope 2, without the need for manual winding, saving time and improving salvage efficiency.

[0039] In some examples, refer to Figure 1-7 As shown, the connecting device 3 includes a moving block 31 and a connecting block 32, wherein: the moving block 31 is sleeved on the salvage rope 2, and the moving block 31 has a vertically penetrating pressing cavity 35 and a positioning cavity 36, and a positioning mechanism 5 for fixing the moving block 31 to the salvage rope 2 is installed in the pressing cavity 35 and the positioning cavity 36.

[0040] Through the above technical solution, after the movable block 31 is sleeved on the salvage rope 2, the positioning mechanism 5 can fix the movable block 31 to the salvage rope 2. At the same time, the position of the movable block 31 can be flexibly changed to facilitate the adjustment of the deployment density of the attachment carrier 4 to meet the deployment requirements of different water bodies for the attachment carrier 4. The pressing cavity 35 and the positioning cavity 36 are used to accommodate the positioning mechanism 5.

[0041] In some examples, refer to Figure 1-7 As shown, the positioning mechanism 5 includes a lifting block 51, a pressing block 52, a driving block 53, a moving block 54, a positioning spring 55, and a positioning block 56. The lifting block 51 and the pressing block 52 are slidably connected within the pressing cavity 35, with the pressing block 52 fixedly installed above the lifting block 51. The pressing block 52 is shorter than the lifting block 51 and is used to drive the lifting block 51 to slide. The driving block 53 is symmetrically installed on both sides of the bottom surface of the lifting block 51 and slidably connected to the pressing cavity 35. The driving block 53 is used to drive two moving blocks 54. The two moving blocks 54 are slidably connected to both sides of the positioning cavity 36 and are used to drive the two positioning blocks 56. The positioning spring 55 is installed between the moving block 54 and the inner wall of the positioning cavity 36. The two positioning blocks 56 are installed on opposite sides of the two moving blocks 54 and located on both sides of the retrieval rope 2. The positioning spring 55 drives the two positioning blocks 56 to clamp the retrieval rope 2 through the moving blocks 54, thereby fixing the moving block 31 to the retrieval rope 2.

[0042] Through the above technical solution, in this invention, the positioning spring 55 drives two positioning blocks 56 to clamp the retrieval rope 2 through the moving block 54, so as to fix the moving block 31 to the retrieval rope 2; when it is necessary to change the position of the moving block 31, the pressing block 52 is pressed, and the pressing block 52 drives two driving blocks 53 to move down through the lifting block 51, so as to drive the two moving blocks 54 to slide in the opposite direction, and the moving block 54 drives the two positioning blocks 56 to release the clamping of the retrieval rope 2, so as to facilitate the change of the position of the moving block 31; the setting that the length of the pressing block 52 is less than that of the lifting block 51 prevents the pressing block 52 and the lifting block 51 from sliding away from the pressing cavity 35.

[0043] In some examples, refer to Figure 1-7 As shown, the two positioning blocks 56 have arc-shaped surfaces 57 on their opposite sides that match the retrieval rope 2. Through the arc-shaped surfaces 57, the two positioning blocks 56 firmly clamp the retrieval rope 2. The drive block 53 has an inclined surface 58, and the moving block 54 has a slidable groove 59 with the same inclination angle as the inclined surface 58. Through the inclined surface 58 and the groove 59, the drive block 53 drives the moving block 54 to slide along the positioning cavity 36.

[0044] Through the above technical solution, the arc-shaped surface 57 in this invention facilitates the two positioning blocks 56 to firmly clamp the retrieval rope 2 and fix the moving block 31 to the retrieval rope 2; the inclined surface 58 and the inclined groove 59 facilitate the driving block 53 to slide the two moving blocks 54 in the opposite direction along the positioning cavity 36 during the sliding process of the pressing cavity 35, so that the two positioning blocks 56 can release the clamping of the retrieval rope 2, and the position of the moving block 31 can be changed.

[0045] In some examples, refer to Figure 1-7 As shown, the movable block 31 is also provided with a connecting groove 33 and a fixing cavity 37. The connecting groove 33 is for the connecting block 32 to be inserted. The fixing cavity 37 is located on both sides of the connecting groove 33 and is equipped with a fixing mechanism 6. After the connecting block 32 is inserted into the connecting groove 33, the fixing mechanism 6 fixes the connecting block 32 to the movable block 31.

[0046] Through the above technical solution, the connection groove 33 in this invention is provided for the connection block 32 to be inserted and connected to the moving block 31; after the connection block 32 is inserted into the connection groove 33, the connection block 32 can be fixed to the moving block 31 by the fixing mechanism 6, and at the same time the connection block 32 can be easily removed from the moving block 31, and the attachment carrier 4 is installed on the connection block 32, thereby facilitating the cleaning of the attachment carrier 4 with water sponge attached; the fixing cavity 37 is used to accommodate the fixing mechanism 6.

[0047] In some examples, refer to Figure 1-7As shown, the fixing mechanism 6 includes a first limiting plate 61, a fixing spring 62, a fixing block 63, a first pull rod 64, and a first handle 65, wherein: the first limiting plate 61 is slidably connected in two fixing cavities 37; the fixing spring 62 is installed between the first limiting plate 61 and the inner wall of the fixing cavity 37, and is used to drive the first limiting plate 61; the fixing block 63 is fixedly installed on the side of the first limiting plate 61 near the connecting groove 33, and corresponds to and matches the fixing hole 39, the fixing block 63 is inserted into the fixing hole 39 to fix the connecting block 32 to the moving block 31; the first pull rod 64 is fixedly installed on the side of the first limiting plate 61 away from the fixing block 63, and is located in the fixing spring 62, the free end of the first pull rod 64 extends out of the fixing cavity 37, and is fixedly connected to the first handle 65.

[0048] Through the above technical solution, in this invention, the fixing spring 62 drives the fixing block 63 to be inserted into the fixing hole 39 through the first limiting plate 61, so as to fix the connecting block 32 to the moving block 31; the first handle 65 drives the first pull rod 64 to move in the opposite direction, so as to drive the first limiting plate 61 to slide in the direction, and the first limiting plate 61 drives the fixing block 63 to disengage from the fixing hole 39, so as to facilitate the removal of the connecting block 32 from the moving block 31 and facilitate the cleaning of the attachment carrier 4 with water hyacinth attached.

[0049] In some examples, refer to Figure 1-7 As shown, the connecting block 32 is provided with an installation groove 34, a locking cavity 38 and a fixing hole 39. The fixing mechanism 6 fixes the connecting block 32 to the moving block 31 through the fixing hole 39. The installation groove 34 is used to accommodate the end of the carrier 4. The locking cavity 38 is located on both sides of the installation groove 34 and is equipped with a locking mechanism 7 to fix the carrier 4 to the connecting block 32.

[0050] Through the above technical solution, the mounting groove 34 in this invention is provided so that the end of the attachment carrier 4 can enter and connect to the connecting block 32; after the attachment carrier 4 enters the mounting groove 34, the locking mechanism 7 can fix the attachment carrier 4 to the connecting block 32, and the attachment carrier 4 can be easily removed from the connecting block 32, which is convenient for cleaning or replacing the attachment carrier 4 with water sponge attached; the locking cavity 38 is used to accommodate the locking mechanism 7; the fixing hole 39 is provided so that the locking mechanism 7 can be inserted to fix the attachment carrier 4 to the connecting block 32.

[0051] In some examples, refer to Figure 1-7As shown, the locking mechanism 7 includes a second limiting plate 71, a locking spring 72, a connecting rod 73, a pressure plate 74, and an insert rod 75, wherein: the second limiting plate 71 is slidably connected in two locking cavities 38; the locking spring 72 is installed between the second limiting plate 71 and the inner wall of the locking cavity 38, and is used to drive the second limiting plate 71; one end of the connecting rod 73 is fixedly installed on the side of the second limiting plate 71 near the mounting groove 34, and the other end extends into the mounting groove 34 and is fixedly connected to the pressure plate 74, the two pressure plates 74 are used to press the attachment carrier 4; the insert rod 75 is installed on the opposite sides of the two pressure plates 74, and the free ends are engaged with each other, the two insert rods 75 are inserted into the attachment carrier 4.

[0052] Through the above technical solution, in this invention, the locking spring 72 drives the pressure plate 74 to press the attachment carrier 4 through the second limiting plate 71 and the connecting rod 73, and the two insert rods 75 are inserted into the attachment carrier 4 through mutual meshing of their free ends, thus firmly fixing the attachment carrier 4 to the connecting block 32.

[0053] In some examples, refer to Figure 1-7 As shown, a second pull rod 78 is fixedly installed on the side of the second limiting plate 71 away from the connecting rod 73. The free end of the second pull rod 78 extends out of the locking cavity 38 and is fixedly connected to the second handle 79. The surfaces on which the two insert rods 75 are connected to each other are provided with a meshing block 76 and a meshing groove 77. The meshing block 76 and the meshing groove 77 mesh with each other to prevent the two insert rods 75 from being misaligned.

[0054] Through the above technical solution, when it is necessary to clean or replace the attachment carrier 4, the second handle 79 drives the second pull rod 78 to move in the opposite direction, thereby driving the second limiting plate 71 and the connecting rod 73 to slide in the opposite direction. The connecting rod 73 drives the two pressure plates 74 to release the pressure on the attachment carrier 4, and at the same time drives the two insertion rods 75 to separate from each other and be pulled out from the inside of the attachment carrier 4, so that the attachment carrier 4 can be cleaned or replaced. The setting of the meshing block 76 and the meshing groove 77 facilitates the connection of the free ends of the two insertion rods 75 and prevents the occurrence of problems.

[0055] The present invention also provides an operation method for the above-mentioned Spirogyra control and retrieval device, specifically: after the attachment carrier 4 is evenly fixed to the retrieval rope 2 at a certain interval through the connecting device 3, the retrieval traction and collection device 1 places the attachment carrier 4 on the water surface through the retrieval rope 2. After the attachment carrier 4 is covered with Spirogyra, the retrieval traction and collection device 1 removes the attachment carrier 4 from the water body through the retrieval rope 2 and cleans off the Spirogyra attached to the attachment carrier 4, and repeats the above operation.

[0056] Through the above technical solution, by deploying multiple sets of salvage ropes 2 on the water surface, the attachment carriers 4 will be evenly distributed on the water surface. After a large amount of spirulina has adhered to the surface of the attachment carriers 4, one set of salvage towing and collection devices 1 pulls the attachment carriers 4 to the shore by reeling in the lines. At the same time, another set of salvage towing and collection devices 1 releases the lines to clean the spirulina on the surface of the attachment carriers 4. Then, another set of salvage towing and collection devices 1 reels in the lines and redeploys the cleaned attachment carriers 4 to the water surface. By repeating the above operation multiple times, the purpose of preventing large-scale outbreaks of spirulina and improving the salvage efficiency of spirulina can be achieved.

[0057] The working principle of this invention is as follows: the rotating turntable 14 drives the rotating shaft 12 to rotate, and the rotating shaft 12 drives the rotating wheel 11 to rotate, thereby driving the release and retraction of the salvage rope 2.

[0058] After the movable block 31 is fitted onto the salvage rope 2, the positioning spring 55 drives the two positioning blocks 56 to clamp the salvage rope 2 through the movable block 54, so as to fix the movable block 31 onto the salvage rope 2; when it is necessary to change the position of the movable block 31, press the pressing block 52, and the pressing block 52 drives the two driving blocks 53 to move down through the lifting block 51, so as to drive the two movable blocks 54 to slide in the opposite direction, and the movable block 54 drives the two positioning blocks 56 to release the clamping of the salvage rope 2, so as to facilitate the change of the position of the movable block 31;

[0059] After the connecting block 32 is inserted into the connecting slot 33, the fixing spring 62 drives the fixing block 63 to be inserted into the fixing hole 39 through the first limiting plate 61, so as to fix the connecting block 32 onto the moving block 31; the first handle 65 drives the first pull rod 64 to move in the opposite direction, so as to drive the first limiting plate 61 to slide in the direction, and the first limiting plate 61 drives the fixing block 63 to disengage from the fixing hole 39, so as to facilitate the removal of the connecting block 32 from the moving block 31;

[0060] After the attachment carrier 4 enters the mounting slot 34, the locking spring 72 drives the pressure plate 74 to press the attachment carrier 4 through the second limiting plate 71 and the connecting rod 73. At the same time, the free ends of the two insert rods 75 mesh with each other and are inserted into the attachment carrier 4, firmly fixing the attachment carrier 4 to the connecting block 32. The second handle 79 drives the second pull rod 78 to move in the opposite direction, so as to drive the second limiting plate 71 and the connecting rod 73 to slide in the opposite direction. The connecting rod 73 drives the two pressure plates 74 to release the pressure on the attachment carrier 4, and at the same time drives the two insert rods 75 to separate from each other and be pulled out from the inside of the attachment carrier 4, so as to facilitate the cleaning or replacement of the attachment carrier 4.

[0061] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
