Description

Technical Field

[0001] This utility model relates to the field of water body ecological restoration technology, specifically to a device for collecting plant debris and algae from the water surface. Background Technology

[0002] In landscape and ecological water bodies such as rivers, lakes, and reservoirs, plant remains produced after the natural decay or harvesting of aquatic plants, along with naturally occurring floating algae such as Spirogyra and Cladosporium, constitute the main floating pollutants on the water surface. These pollutants not only severely damage the visual landscape, but also consume large amounts of dissolved oxygen and release endogenous nutrients during their decomposition, leading to secondary pollution and continuously exacerbating water quality deterioration and ecological degradation.

[0003] Currently, the handling of such floating debris relies mainly on manual dredging or fixed trash racks. Manual dredging is inefficient, costly, and unsafe; fixed racks can only passively intercept pollutants and cannot actively collect and efficiently remove them. Furthermore, most existing surface cleaning equipment focuses solely on dredging and collection, lacking efficient water circulation capabilities. Excellent water circulation plays a crucial role in breaking up static water stratification, increasing dissolved oxygen, and inhibiting algae regeneration; current technologies struggle to effectively coordinate these two functions of pollutant collection and water activation. Utility Model Content

[0004] The purpose of this application is to address the shortcomings of the aforementioned background technology and provide a device for collecting aquatic plant debris and algae.

[0005] The technical solution of this application is: a device for collecting aquatic plant remains and algae, comprising: The collection chamber is a hollow cavity structure with openings at both the top and bottom, and the top opening being below the water surface of the water to be treated. The driving structure includes a vertical cylinder installed at the lower opening of the collection chamber and a first impeller installed inside the vertical cylinder. The first impeller is a rotating structure that can rotate forward to drive the water in the collection chamber to flow from top to bottom and can rotate in reverse to drive the water in the collection chamber to flow from bottom to top. The filter screen is a flexible mesh structure with its circumferential side fixed to the lower opening of the collection chamber. An adjustment structure is provided inside the collection chamber. When the first impeller rotates forward, the adjustment structure drives the center of the filter screen to move downward into the vertical cylinder, so that the filter screen forms a cone-shaped collection net with a larger top and a smaller bottom and the opening facing the collection chamber. When the first impeller rotates in reverse, the adjustment structure drives the center of the filter screen to move upward into the collection chamber, so that the filter screen forms a cone-shaped structure with a smaller top and a larger bottom and the opening facing the vertical cylinder.

[0006] According to the aquatic plant debris and algae collection device provided in this application, the device further includes a collection structure; the collection structure includes, A rotating shaft is vertically inserted through the vertical cylinder and the collecting cavity, and is connected to the first impeller via a transmission. The water inlet impeller includes multiple blades arranged circumferentially; one end of each blade is fixedly connected to the rotating shaft via a transmission frame, and the other end extends radially outward from the collection chamber. The multiple blades form a conical ring structure that is larger at the top and smaller at the bottom, with the smaller end connected to the upper opening of the collection chamber.

[0007] According to the present application, a device for collecting aquatic plant debris and algae is provided. The adjustment structure includes an adjustment block and an adjustment rod. The adjustment rod is arranged vertically, with its upper end connected to the adjustment block and its lower end fixed to the center of the filter screen. The adjustment block is a block-shaped structure located above the filter screen and its buoyancy can be adjusted by air inflation or drainage. When the first impeller rotates forward, the adjustment block reduces buoyancy to drive the center of the filter screen to move into the vertical cylinder. When the first impeller rotates in reverse, the adjustment block increases buoyancy to drive the center of the filter screen to move into the collection chamber.

[0008] According to the present application, a device for collecting aquatic plant debris and algae is provided, wherein the adjusting block is a ring-shaped structure that is looped around a rotating shaft and can move axially along the rotating shaft; a collar is installed at the center of the filter screen; the collar is axially movable and is fitted onto the rotating shaft.

[0009] According to the present application, a device for collecting aquatic plant debris and algae is provided, wherein the vertical cylinder is provided with a walking structure that can drive the collection chamber to move horizontally in the water.

[0010] According to the present application, a device for collecting aquatic plant debris and algae is provided, wherein the walking structure includes four second impellers, which are arranged in pairs opposite each other on the outer circumference of the vertical cylinder; the second impellers are a rotary drive structure that can rotate around a horizontal axis.

[0011] According to the present application, a device for collecting aquatic plant debris and algae includes a horizontal cylinder corresponding to a second impeller; the second impeller is disposed inside the horizontal cylinder; one end of the horizontal cylinder is connected to the side of the vertical cylinder, and the other end extends horizontally away from the vertical cylinder; a first valve is provided at the connection between the horizontal cylinder and the vertical cylinder to control the connection or disconnection between the horizontal cylinder and the vertical cylinder; and a second valve is provided on the horizontal cylinder body between the second impeller and the first valve to control the connection or disconnection between the inner and outer sides of the horizontal cylinder.

[0012] According to the present application, a device for collecting aquatic plant debris and algae is provided at the lower end of the vertical cylinder, which connects the lower end of the vertical cylinder to the external water body when the first impeller rotates forward and closes the lower end of the vertical cylinder to isolate the inside and outside of the vertical cylinder when the first impeller rotates in reverse.

[0013] According to the present application, a device for collecting aquatic plant debris and algae is provided, wherein the collection chamber is a hollow sphere with a diameter larger than that of a vertical cylinder.

[0014] According to the present application, a device for collecting aquatic plant debris and algae is provided, wherein the collection chamber is equipped with a float with adjustable buoyancy.

[0015] The advantages of this application are as follows: 1. The collection device of this application has high-efficiency collection and self-cleaning capabilities. By controlling the direction of water flow through the forward and reverse rotation of the first impeller, the device can switch between collection mode (water flows from top to bottom when rotating forward) and cleaning mode (water flows from bottom to top when rotating reverse). When rotating forward, the filter screen forms a cone-shaped collection net, effectively capturing floating objects on the water surface. When rotating reverse, the filter screen deforms into an inverted cone-shaped structure, using the reverse water flow to flush away the debris accumulated on the filter screen, preventing clogging and achieving automatic cleaning, greatly reducing the need for manual maintenance. The filter screen of this application adopts a flexible mesh structure and automatically changes its shape by adjusting the structure to adapt to different environments. With different operating modes, this design avoids the problem of rigid filter screens being easily clogged, improving the reliability and service life of the device, and is especially suitable for the treatment of algae and other easily attached debris; the entire device is based on the principle of fluid mechanics, using the first impeller to drive the water flow, eliminating the need for a complex mechanical transmission system, reducing manufacturing costs and failure rate, while the forward and reverse operation optimizes energy utilization, enabling efficient operation during both collection and cleaning processes; the upper opening of the collection chamber in this application is placed below the water surface, allowing direct collection of floating debris, and is suitable for various aquatic environments such as lakes, ponds, and reservoirs, with significant effects on controlling algal blooms and eutrophication; 2. The inlet impeller of this application consists of multiple blades forming a conical ring structure. When rotating, it generates vortices that actively guide floating objects to the upper opening of the collection chamber, expanding the collection range and reducing omissions. The conical structure helps to concentrate the water flow, making it easier for floating objects to enter the collection chamber. The rotating shaft of this application connects the first impeller to the inlet impeller, realizing power sharing and eliminating the need for an additional drive source, thus reducing energy consumption and complexity. This integrated design makes the device structure more compact and improves overall coordination. The blade design of the inlet impeller optimizes the water flow pattern, reduces turbulence, and allows floating objects to enter the collection chamber smoothly, avoiding a decrease in collection efficiency caused by water flow turbulence. 3. The adjusting block of this application changes buoyancy by inflating or deflating, and automatically drives the filter center to move according to the direction of the first impeller. When rotating forward, the buoyancy decreases, causing the filter to sink and form a collection net; when rotating in reverse, the buoyancy increases, causing the filter to rise and form an inverted cone structure. This buoyancy-based adjustment mechanism responds quickly, improving reliability and adaptability. The adjusting rod connects the adjusting block and the filter center, transmitting buoyancy changes. The structure is simple and durable, reducing moving parts and maintenance costs. The block design of the adjusting block is easy to manufacture and install, and is suitable for underwater environments. The buoyancy adjustment is synchronized with the direction of the first impeller, ensuring rapid switching between collection and cleaning modes, improving operational efficiency, and avoiding collection interruptions caused by mode switching delays. 4. The adjusting block of this application is ring-fitted on the rotating shaft and can move axially. The center of the filter screen is fitted onto the rotating shaft through the ring. This design ensures stable movement of the filter screen in the vertical direction, prevents the filter screen from tilting or jamming, and improves operational reliability. The fit between the ring and the rotating shaft allows for smooth axial movement, reduces friction between components, extends the service life of the device, and the ring structure saves space, making the overall design more compact. The modular design makes the adjusting block and filter screen easy to disassemble and replace, reducing maintenance difficulty. 5. The collection device of this application can move freely in water areas, expand the cleaning range, and carry out targeted collection in heavily polluted areas, thereby improving the overall cleaning efficiency. This is particularly beneficial for large water areas such as lakes or rivers. The walking structure allows the device to adapt to different water terrain and environmental changes, realize autonomous or remote control operation, reduce human intervention, and lower labor costs. The walking structure is combined with the drive structure, eliminating the need for external traction equipment, making the device self-contained, and facilitating deployment and recovery. 6. The four second impellers of this application are placed on the outer side of the vertical cylinder circumference, providing stable propulsion and allowing the device to perform complex movements such as forward, backward, and turning on the horizontal plane, thus enhancing maneuverability; the arrangement of the two opposing impellers ensures the balance of propulsion, prevents the device from tilting or rotating, and improves operational stability, especially in wave environments; impeller drive is an efficient way to move in water, with fast response speed and simple control, and precise movement can be achieved by adjusting the impeller speed; 7. This application optimizes the water flow path by controlling the connection between the horizontal and vertical cylinders with the first valve and the connection between the inner and outer sides of the horizontal cylinder with the second valve. When moving, opening the valves allows water to flow through the second impeller, providing propulsion. When collecting at rest, the second impeller can work in tandem with the first impeller to drive the water flow from top to bottom, enhancing the collection effect. The horizontal cylinder provides a sealed space for the second impeller, providing a more concentrated propulsion force for the collection device when moving, reducing disturbance to the bottom of the water and preventing the suction of sediment into the collection chamber. The valve control allows for selective use of the walking structure, avoiding unnecessary energy consumption and enabling the device to switch efficiently between collection and movement modes. 8. In this application, when the first impeller rotates forward (collection mode), the third valve opens, allowing the lower end of the vertical cylinder to connect with the external water body, promoting downward water flow and enhancing the collection effect; when rotating in reverse (cleaning mode), the third valve closes, isolating the inside and outside of the vertical cylinder, and the reverse water flow concentrates to flush the filter screen, improving cleaning efficiency; in cleaning mode, the third valve is closed and the second valve is opened, allowing water from the outside of the horizontal cylinder to enter the collection chamber for flushing, avoiding the intake of sediment from the bottom; the valve operation is simple, linked with the first impeller, realizing automated control and reducing manual intervention; 9. The spherical shape of the collection chamber in this application has a large upper opening, which can cover a wider water surface area, collect more floating objects, and increase the processing capacity per unit time. The spherical structure helps water flow smoothly into the collection chamber, reducing eddies and energy loss, making it easier to capture floating objects. At the same time, the sphere withstands water pressure evenly, has high structural strength, and good durability. The sphere is easy to manufacture and install, and is suitable for various aquatic environments without affecting the landscape. 10. The pontoon of this application, by adjusting buoyancy, enables the device to float at the optimal depth below the water surface, adapting to water level changes and wave effects, and ensuring that the upper opening of the collection chamber is always in the ideal position below the water surface; buoyancy adjustment allows the device to operate stably under different water conditions (such as deep water areas and shallow water areas), avoiding the decrease in collection efficiency caused by sinking or floating too high; the pontoon adjustment can be based on sensors or manual control to achieve automated management, reduce debugging time, and improve deployment efficiency.

[0016] The collection device of this application has the advantages of high efficiency, adaptability and multifunctionality, realizing the automatic collection and cleaning of plant debris and algae on the water surface, and has significant environmental management value and commercial application prospects.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0021] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] This application relates to a device for collecting surface plant debris and algae. It draws surface plant debris and algae into a collection chamber by actively creating a current, and uses a filter in the collection chamber to collect these debris and algae. After collection, the device can discharge the collected debris and algae by creating a reverse current, which is convenient and quick to clean. The overall device has a simple structure, is easy to use, and has the advantages of high efficiency, self-adaptability, and multi-functionality, realizing the automatic collection and cleaning of surface plant debris and algae.

[0023] Specifically, such as Figures 1-3As shown, a device for collecting aquatic plant debris and algae according to this application includes a collection chamber 1, a drive structure, and a filter screen 5. The collection chamber 1 is a hollow cavity with openings at both the top and bottom, and its material can be engineering plastic or stainless steel. During installation, its upper opening is submerged below the surface of the water to be treated. The drive structure includes a vertical cylinder 2 fixedly installed at the lower opening of the collection chamber 1, and a first impeller 3 installed inside the vertical cylinder 2. The first impeller 3 is driven by a waterproof motor, which can receive external signals to control the first impeller 3 to rotate in either the forward or reverse direction. The filter screen 5 is made of flexible nylon mesh, and its circumferential edge is fixedly installed at the lower opening of the collection chamber 1 by clamps or bolts. An adjustment structure is also provided inside the collection chamber 1 to change the center position and shape of the filter screen 5 according to the rotation direction of the first impeller 3. When the first impeller 3 rotates forward, the adjustment structure drives the center of the filter screen 5 to move downward into the vertical cylinder 2, so that the filter screen 5 forms a cone-shaped collection net with a larger top and a smaller bottom and the opening facing the collection chamber 1. When the first impeller 3 rotates in reverse, the adjustment structure drives the center of the filter screen 5 to move upward into the collection chamber 1, so that the filter screen 5 forms a cone-shaped structure with a smaller top and a larger bottom and the opening facing the vertical cylinder 2.

[0024] This device combines controllable water flow with the shape change of the flexible filter screen 5 to achieve a dual function of "collection and cleaning". When the first impeller 3 rotates clockwise, it generates a downward suction force in the vertical cylinder 2, driving the water in the collection chamber 1 to flow from top to bottom. This water flow will suck in floating plant debris and algae into the collection chamber 1. At the same time, under the active driving action of the adjustment structure, the center of the filter screen 5 is pulled downward into the vertical cylinder 2. Since the edges of the filter screen 5 are fixed, the downward movement of the center causes it to naturally deform into a cone-shaped collection net that is larger at the top and smaller at the bottom, with the opening facing the collection chamber 1, thus effectively catching and trapping debris in the water. When the first impeller 3 rotates counterclockwise, it generates an upward thrust in the vertical cylinder 2, driving the water to flow from bottom to top. At the same time, the adjustment structure drives the center of the filter screen 5 to move upward into the collection chamber 1, deforming the filter screen 5 into an inverted cone-shaped structure that is smaller at the top and larger at the bottom, with the opening facing the vertical cylinder 2. At this time, the upward water flow will flush the trapped debris off the filter screen 5 and discharge it through the upper opening of the collection chamber 1, thus achieving self-cleaning of the filter screen 5.

[0025] During use, the operator sends commands to the waterproof motor via remote control or a preset program. A forward rotation command is sent when water collection is needed; a reverse rotation command is sent when filter 5 needs cleaning. The duration of forward and reverse rotation can be set according to the degree of water pollution.

[0026] The collection device of this application integrates collection and cleaning functions into a single unit, which can be completed through a simple impeller rotation switch, solving the problems of easy clogging and inconvenient cleaning of traditional collection devices. The flexible filter 5, in conjunction with the drive structure, can automatically form the most suitable geometry for collection or cleaning, significantly improving work efficiency and reliability. The collection device has few core components and a single power source, reducing manufacturing costs and failure rates, and facilitating promotion and application.

[0027] In some embodiments of this application, a collection structure is installed on the collection cavity 1. For example... Figures 1-2 As shown, the collection structure includes a rotating shaft 4 that runs vertically through the vertical cylinder 2 and the collection chamber 1. A first impeller 3 is fixedly mounted on the lower end of the rotating shaft 4 and is driven to rotate synchronously by the shaft 4. The collection structure also includes a water inlet wheel 6, which consists of a transmission frame and multiple blades. The transmission frame is fixedly connected to the upper part of the rotating shaft 4. The multiple blades are evenly arranged circumferentially, and the blades are helical, such as... Figure 3 As shown, the blades are fixed to the transmission frame, with one end of each blade close to the rotating shaft 4 and the other end extending radially outward to the outside of the collection chamber 1. All the blades together form a conical ring structure that is larger at the top and smaller at the bottom, with its smaller end spatially connected to the upper opening of the collection chamber 1.

[0028] While driving the first impeller 3 to rotate, the rotating shaft 4 also drives the inlet impeller 6 to rotate synchronously. The rotating inlet impeller 6 exerts a tangential force on the water surface and surface water, forming a gentle vortex or converging flow. This vortex can effectively "sweep" the plant debris and algae scattered on the water surface and gather them near the upper opening of the collection chamber 1, thereby expanding the collection range of a single operation.

[0029] The collection structure added in this embodiment can actively converge, improving collection efficiency. The inlet wheel 6, as a front-mounted "sweeping" mechanism, changes the passive waiting mode of waiting for floating objects to enter the collection chamber 1 with the natural water flow, actively expanding the effective collection area. It is particularly suitable for scenarios where floating objects are sparsely distributed or the water area is large, significantly increasing the collection volume per unit time.

[0030] In other embodiments of this application, the above-described adjustment structure has been optimized, specifically, as follows: Figures 1-2 As shown, the adjustment structure includes an adjustment block 7 and multiple adjustment rods. The adjustment rods are arranged vertically, with their upper ends connected to the adjustment block 7 and their lower ends fixed to the center point of the filter screen 5. The adjustment block 7 has a hollow internal structure and is connected to a miniature air pump and a solenoid valve (not shown in the figure), making it a block-shaped structure whose buoyancy can be changed by inflating or deflating.

[0031] The adjusting structure operates on the principle of buoyancy control. When the device enters the collection mode (first impeller 3 rotates forward), the control system controls the adjusting block 7 to vent or introduce water, reducing its buoyancy. With the assistance of gravity or downward water flow, the adjusting block 7 moves the adjusting rod and the center of the filter screen 5 downward, forming a collection net. When the device switches to the cleaning mode (first impeller 3 rotates in reverse), the control system controls the adjusting block 7 to inflate or depressurize, increasing its buoyancy. Under the increased buoyancy, the adjusting block 7 floats upward, pulling the center of the filter screen 5 upward via the adjusting rod, forming an inverted cone-shaped structure, which, in conjunction with the reverse water flow, completes the cleaning process.

[0032] In actual use, the control unit synchronously coordinates the rotation of the first impeller 3 with the buoyancy adjustment of the adjusting block 7. A forward rotation command triggers the venting / water intake action; a reverse rotation command triggers the inflation / draining action.

[0033] The adjustment structure in this embodiment offers precise control and rapid response. Utilizing buoyancy as the driving source results in high energy efficiency, smooth operation, and reliable performance. This mechanical-buoyancy linkage control method avoids complex mechanical transmission mechanisms, simplifies the structure, and improves long-term operational stability in underwater environments.

[0034] In addition, this embodiment also optimizes the arrangement structure of the adjusting block 7 and the filter screen 5, specifically, as follows: Figures 1-2 As shown, the adjusting block 7 is specifically designed as a ring-shaped structure with a through hole in its center, allowing it to be fitted onto the rotating shaft 4 and slide freely up and down along the axial direction of the rotating shaft 4. Simultaneously, a collar is fixedly installed at the center of the filter screen 5, which is also slidably fitted onto the rotating shaft 4. The upper end of the adjusting rod is hinged to the ring-shaped adjusting block 7, and the lower end is hinged to the collar.

[0035] In this embodiment, the rotating shaft 4 acts as a guide rod. When the adjusting block 7 moves up and down due to changes in buoyancy, its movement is constrained in the vertical direction by the rotating shaft 4, and the movement is precisely transmitted to the collar through the adjusting rod, thereby driving the center of the filter screen 5 to move along a predetermined trajectory. This ensures that the filter screen 5 will not shift or twist in the horizontal direction during deformation, making the shape change more stable and controllable.

[0036] In further embodiments of this application, such as Figures 1-2 As shown, this embodiment adds mobility to the device based on the above. A walking structure is installed on the outer wall of the vertical cylinder 2. The walking structure provides the device with horizontal propulsion, enabling it to navigate autonomously in the water, thus overcoming the limitations of fixed operations or reliance on external vessels for towing, and achieving targeted cleaning in different areas or large-scale patrol cleaning. Operators send forward, backward, and turning commands to the walking structure through a remote control system (such as radio remote control) to control its movement path.

[0037] like Figures 1-2 As shown, the traveling structure includes four second impellers 9. These four second impellers 9 are respectively mounted on the outer side of the vertical cylinder 2 in four directions (e.g., front, back, left, and right) via brackets, and the rotation axis 4 of each second impeller 9 is horizontal. Each second impeller 9 is driven by an independent waterproof motor.

[0038] By controlling the rotational speed and direction of the four second impellers 9, propulsive forces in different directions can be synthesized. For example, driving the two front and two rear impellers to rotate in the same direction simultaneously can achieve forward or backward movement; driving the two left and two right impellers to rotate in opposite directions can achieve turning in place; and through differential control, more complex translational movements can also be achieved.

[0039] In operation, a mature vector propulsion control algorithm is employed. After receiving the movement command, the control unit calculates and outputs the specific speed and direction signals of each of the 9 motors of the second impeller.

[0040] This embodiment uses a walking structure to drive the entire collection device to move horizontally, making it very flexible to operate. It employs four horizontally arranged second impellers 9 to form a vector propulsion system, giving the device extremely high mobility and enabling it to flexibly navigate through narrow or complex water environments to complete precise cleaning tasks.

[0041] In a preferred embodiment of this application, the walking structure described above has been further optimized. For example... Figures 1-2 As shown, each second impeller 9 is equipped with a horizontal cylinder 8. One end of the horizontal cylinder 8 is connected to the side wall of the vertical cylinder 2, and the other end extends outward in a horizontal direction. The second impeller 9 is placed inside the horizontal cylinder 8. At the connection between the horizontal cylinder 8 and the vertical cylinder 2, a first valve 10 is installed, which controls whether the horizontal cylinder 8 and the vertical cylinder 2 are connected or disconnected. On the cylinder wall of the horizontal cylinder 8, located between the second impeller 9 and the first valve 10, a through hole is opened and a second valve 11 is installed, which controls whether the horizontal cylinder 8 is connected or disconnected from the inside.

[0042] When the device needs to be moved, the second valve 11 opens and the first valve 10 closes. The second impeller 9 rotates, drawing water from outside the horizontal cylinder 8 into the horizontal cylinder 8 through the second valve 11. The water is then discharged through the end of the horizontal cylinder 8 furthest from the vertical cylinder 2, generating a reverse thrust that drives the collection device to move horizontally. At this time, the first valve 10 is closed to avoid creating a negative pressure in the collection chamber 1 and the vertical cylinder 2, thus preventing interference with the collection chamber 1. When the device is stationary and collecting water, the first valve 10 opens, the second valve 11 closes, and the second impeller 9 rotates, drawing water from the vertical cylinder 2 into the vertical cylinder 2. The water flow in the horizontal cylinder 8, combined with the rotation of the first impeller 3, creates a suction force, allowing the water at the upper opening of the collection chamber 1 to be drawn into the collection chamber 1 more efficiently. When the device needs cleaning, the first valve 10 opens, the second valve 11 closes, and the second impeller 9 rotates in the opposite direction, generating a water flow from the horizontal cylinder 8 to the vertical cylinder 2 (the water flows in from the end of the horizontal cylinder 8 away from the vertical cylinder 2, passes through the first valve 10, and enters the vertical cylinder 2). Combined with the reverse rotation of the first impeller 3, this generates a stronger upward water flow, resulting in a better rinsing effect on the filter screen 5 and preventing clogging.

[0043] During use, the control unit links the walking command with the valve control. When walking starts, the second impeller 9 rotates forward, opening the second valve 11 and closing the first valve 10; when walking stops for collection, the second impeller 9 rotates forward, opening the first valve 10 and closing the second valve 11; when walking stops for cleaning, the second impeller 9 rotates in the reverse direction, opening the first valve 10 and closing the second valve 11.

[0044] In this embodiment, the second impeller 9, the first valve 10, and the second valve 11 work together to efficiently realize the translation of the collection device. During the collection and cleaning process, they can also work with the first impeller 3 to generate a stronger collection water flow or cleaning water flow.

[0045] In some embodiments of this application, the structure of the vertical cylinder 2 described above has been optimized. Based on any previous embodiment, a third valve 12 is installed at the lower opening of the vertical cylinder 2. The third valve 12 controls the connection or isolation between the inside and outside of the vertical cylinder 2.

[0046] In the collection mode (first impeller 3 rotating forward), the third valve 12 is open, ensuring unobstructed flow between the lower end of the vertical cylinder 2 and the external water body, forming a complete and smooth downward water flow channel, which is conducive to collection. In the cleaning mode (first impeller 3 rotating backward), the third valve 12 is closed, sealing the lower end of the vertical cylinder 2 to prevent sediment from the bottom of the water from entering the vertical cylinder 2. At this time, the first valve 10 is open, and the water flow from bottom to top enters the vertical cylinder 2 through the horizontal cylinder 8. Under the synergistic action of the first impeller 3 and the second impeller 9, the generated high-speed water flow can perform a powerful and efficient reverse flushing of the filter screen 5.

[0047] In actual operation, the control unit synchronizes the control of the third valve 12 with the rotation direction of the first impeller 3. When rotating forward, the third valve 12 is open; when rotating in reverse, the third valve 12 is closed.

[0048] This embodiment optimizes the water flow path and improves cleaning efficiency. By opening and closing the third valve 12, the water flow is guided and constrained, especially in cleaning mode, creating a local high-pressure flushing environment. This greatly enhances the self-cleaning effect of the filter screen 5 and also prevents sediment from entering the vertical cylinder 2 and collection chamber 1, thus avoiding damage to the device.

[0049] In other embodiments of this application, the shape of the collecting cavity 1 is specifically defined. The collecting cavity 1 is designed as a hollow sphere, and its diameter is significantly larger than the diameter of the vertical cylinder 2 connected to its lower end.

[0050] The spherical collection chamber 1 has an optimal hydrodynamic shape, resulting in low resistance and minimal turbulence as water flows over its surface. The large diameter of the sphere means a larger opening area at its upper end, resembling an open "mouth," capable of accommodating a wider range of floating debris. The spherical cavity structure not only improves single-cycle collection efficiency but also reduces energy loss due to its smooth inner and outer contours, making the collection process smoother and more efficient.

[0051] In fact, the collection chamber 1 can also be designed as a converging structure with a large upper opening and a small lower opening, which allows for a wide collection range and a small lower opening, making it easier to intercept plant debris and algae.

[0052] In a further embodiment of this application, one or more buoyancy-adjustable floats 13 are installed on the outer wall of the collection chamber 1. Figures 1-2 As shown, the interior of the float 13 is a cavity, which is also connected to the inflation / deflation and drainage systems.

[0053] By adjusting the buoyancy of the float 13, the draft of the entire device in the water can be precisely controlled. For example, in windy and wavery conditions, buoyancy can be increased to bring the device closer to the water surface and maintain operational stability; when it is necessary to avoid surface debris and collect algae at a specific depth in the water, buoyancy can be reduced to allow the device to sink.

[0054] The inflation and deflation and water intake / exhaust of the floating box 13 can be controlled automatically or manually based on preset depth or real-time sensor feedback.

[0055] The float 13 is designed for adaptive water depth operation, ensuring high operational stability. The adjustable buoyancy of the float 13 makes the device an intelligent floating body, capable of adapting to complex hydrological conditions (such as tides, waves, and water level changes), always keeping the collection port at the optimal working depth, thus guaranteeing consistent and reliable collection results.

[0056] In practical use, the aquatic plant debris and algae collection device of this application is lowered into the water area to be treated. The buoyancy of the float 13 is adjusted so that the collection chamber 1 and the inlet impeller 6 are 5cm to 10cm below the water surface. After adjustment, the collection device is moved by closing the first valve 10 and opening the second valve 11, which activates the second impeller 9. The rotation of the second impeller 9 generates thrust, driving the collection device to the location in the water area to be treated. Once at the designated location, the collection of plant debris and algae begins. The second valve 11 is closed, and the first valve 10 and the third valve 12 are opened, driving the first impeller 3 and the second impeller 9 to rotate clockwise, generating a downward water flow. The inlet impeller 6 rotates with the first impeller 3, sucking the plant debris and algae from the water surface into the collection chamber 1. When the first impeller 3 begins to rotate, the buoyancy of the adjusting block 7 is lowered, causing the adjusting block 7 to move downwards and driving the filter screen. The center of filter 5 moves downward into the vertical cylinder 2, forming a cone-shaped collection net that is wider at the top and narrower at the bottom. Plant debris and algae sucked into the collection chamber 1 are collected by filter 5, and the plant debris and algae accumulate on the side of filter 5 facing away from the vertical cylinder 2. After collection is completed, the collection device is controlled to move horizontally according to the above method until it is moved to a position that is convenient for the operator to collect. The second valve 11 and the third valve 12 are closed, and the first valve 10 is opened. The first impeller 3 and the second impeller 9 rotate in opposite directions, controlling the buoyancy of the adjusting block 7 to rise. The adjusting block 7 drives the center of filter 5 to move upward into the collection chamber 1. The first impeller 3 and the second impeller 9 reverse to generate a water flow from bottom to top. This water flow washes the filter 5, causing the plant debris and algae intercepted on the filter 5 to fall off the filter 5, making it convenient for the operator to clean. After cleaning is completed, the collection device is driven to move to the next collection position for the next collection according to the above steps.
