Description

Technical Field

[0001] This invention relates to the field of cyanobacteria removal technology, and in particular to a small boat and method for cyanobacteria removal. Background Technology

[0002] Dianchi Lake, the largest freshwater lake in Yunnan Province, is a breeding ground for cyanobacteria, which proliferate wildly every summer. Large-scale cyanobacteria blooms turn the lake water a deep green, obscuring the bottom, with rolling green waves surging towards the shore, accompanied by a foul odor. Besides deteriorating water quality, this depletes oxygen, causing fish deaths. More seriously, some types of cyanobacteria are a significant contributing factor to liver cancer. To restore Dianchi Lake to its former glory, my country invested heavily in remediation between 1996 and 2020, spending over 70 billion yuan. Key projects included constructing separate stormwater and sewage pipelines, treating rivers flowing into the lake, dredging, building new sewage treatment plants, expanding wetlands, and implementing the Niulan River water diversion project. These measures have had some effect; the black and odorous water in the main rivers flowing into the lake has largely disappeared, and sewage discharge has been controlled. However, some areas still suffer from persistent cyanobacteria blooms.

[0003] Blue-green algae blooms are a significant environmental problem facing global aquatic ecosystems, seriously threatening the ecological balance of water bodies and the safety of human water use. Currently, the cleanup of algal pollutants in rivers and lakes mainly relies on manual harvesting, mechanical harvesting, and chemical treatment. While manual harvesting is highly flexible, it is inefficient and labor-intensive, making it difficult to cope with large-scale blue-green algae blooms. Traditional mechanical harvesting equipment often uses fixed cutting and single conveying structures. For example, disc-type cutting boats have problems such as unadjustable cutting depth and susceptibility to clogging by algae clumps, resulting in low cleanup efficiency. Furthermore, the equipment has poor stability and is prone to drifting in areas with rapid currents, affecting the effectiveness of the operation. Chemical treatment methods are prone to causing secondary pollution and damaging the aquatic ecological environment, which is inconsistent with the concept of green environmental protection.

[0004] Existing cleaning equipment generally suffers from a single energy source and insufficient endurance, relying heavily on fuel power, which not only results in high operating costs but also generates exhaust pollution. A few electric devices, lacking efficient energy storage and multi-energy complementary systems, cannot meet the demands of long-term continuous operation. Furthermore, the equipment has a low level of intelligence, making it difficult to dynamically adjust operating parameters based on algae density and the aquatic environment, leading to resource waste and incomplete cleaning. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a small boat for cleaning blue-green algae and a cleaning method thereon.

[0006] The blue-green algae cleaning boat and cleaning method provided by this invention adopt the following technical solution: Firstly, a small boat for collecting and cleaning algae pollutants in rivers and lakes is proposed. It includes a hull composed of two suspended bodies, a support frame located between the two hulls providing a mounting area for components, a cleaning component mounted above the support frame for transporting and cleaning algae pollutants, a dumping collection box located at the end of the cleaning component for collecting algae pollutants, and a power supply drive component mounted on the support frame providing the driving force and electricity required for the operation of the cleaning component and the dumping collection box. After the hull moves to a predetermined position, the cleaning component begins to cut and transport the algae into the dumping collection box.

[0007] Preferably, the hull includes: a suspended body with an internal cavity and filled with air, and a connecting frame disposed inside the suspended body and connected to the support frame, wherein the suspended body provides the buoyancy required for the operation and movement of the entire equipment.

[0008] Preferably, the cleaning component includes: a conveying structure set at a predetermined angle to transport the collected algae from the collection direction to the dumping collection box; a cutting structure fixed to the end of the conveying structure away from the dumping collection box; the cutting structure cuts the floating algae and guides it to the conveying structure; and the conveying structure transports the floating algae to the dumping collection box.

[0009] Preferably, the cutting structure includes: a connecting bracket fixed to the conveying structure; a guide frame located inside the connecting bracket with an adjustable guide angle; a cutting bracket fixed to the outside of the connecting bracket and providing a connecting and bearing area for the cutting component; and a cutting blade rotatably connected to the cutting bracket and performing a cutting action on the floating algae. The shape of the end of the guide frame near the cutting blade is adapted to the movement trajectory of the cutting blade.

[0010] Preferably, the conveying structure includes: a conveying positioning frame, a conveyor belt located inside the conveying positioning frame, multiple conveying baffles evenly spaced along the circumference of the conveyor belt, a main drive bearing wheel located at one end inside the conveyor belt and providing the driving force required for the movement of the conveyor belt, a driven support frame connected to the conveying positioning frame, and a driven roller shaft disposed inside the driven support frame and rotatably connected thereto. The driven roller shaft supports the conveyor belt while cooperating with the main drive bearing wheel to ensure its conveying stability.

[0011] The cooperation between the main drive roller and the driven roller ensures the stability and efficient operation of the conveyor belt. The main drive roller provides power, propelling the conveyor belt forward; while the driven roller supports the conveyor belt, ensuring that it does not experience unnecessary resistance or deviation during operation. Through the action of the conveyor baffles, the conveying speed and direction of the material are effectively controlled, preventing algae from scattering or accumulating during transport, thus ensuring the high efficiency of the conveying process.

[0012] Preferably, the dumping collection box includes: a dumping support base fixed to the support frame at one end of the output direction of the cleaning component; a dumping box body rotatably connected to the dumping support base above it; a sliding support frame with sliding grooves on both sides of the dumping box body; and a dumping bracket rotatably connected to the sliding support frame at one end and to the dumping box body at the other end. During the dumping process, the dumping bracket slides along the sliding support frame, and the angle of the sliding support frame changes.

[0013] Preferably, the tilting support base includes: a connecting frame integrally formed with the tilting support base and providing a rotating connection area for the tilting collection box; a groove formed on the connecting frame and providing a component installation area; and a detection component fixed inside the groove for detecting data of the tilting collection box.

[0014] Preferably, the power supply drive assembly includes: a mounting frame connected to the support frame and mounted above the cleaning assembly; a drive motor fixed to the mounting frame and providing the power required for the operation of the conveying structure; a mounting platform located at the upper end of the mounting frame; and a power supply unit providing the power required for the overall drive of the equipment.

[0015] Firstly, a method for cleaning cyanobacteria using a small boat is proposed, including the following steps: S1. The solar panel and wind power generation structure work together to provide power, the blade battery enters standby mode, and the remaining capacity of the tilt collection box is checked by an infrared sensor camera to ensure that the box is empty. S2. The small boat is supported by two suspended bodies and drives the propulsion blades through the propulsion structure to sail to the area where blue-green algae gather. S3. Adjust the angle of the guide frame, start the drive motor of the cutting blade, the main drive bearing wheel drives the conveyor belt to run, the conveyor baffle 5 prevents algae fragments from sliding down, and the conveyor belt guides the cut blue algae from the cleaning area to the collection box. S4. Blue-green algae fragments fall into the dumping box at the end of the conveyor belt. The infrared sensor camera of the detection component monitors the filling amount in real time. When the filling rate of the box reaches the dumping requirement, the dumping bracket slides along the slide groove of the sliding support frame, causing the dumping box to tilt. The blue-green algae inside is dumped to the shore collection point or transport ship by gravity.

[0016] S5. When it is necessary to change the working area, the propeller drives the propulsion blades to increase their rotation speed to adapt to complex water terrain. S6. Close the cutting and conveying structures to prepare for the next operation.

[0017] In summary, the present invention has the following beneficial technical effects: The boat's dual-floating hull design, combined with an inflatable cavity to adjust buoyancy, ensures stability in different water depths and currents. The guide frame of the cutting structure in the cleaning component can be flexibly adjusted in angle, and combined with high-speed rotating cutting blades, it can accurately adapt to different densities of algae, effectively reducing the risk of blockage in the conveying structure. The coordinated design of the conveyor belt, main drive bearing wheel, and driven roller shaft, along with equidistant conveying baffles, ensures a stable algae conveying speed.

[0018] The dumping collection box is equipped with an infrared sensor camera to monitor the filling volume in real time. When the set threshold is reached, the dumping bracket and the sliding support frame automatically cooperate to complete the dumping action, which improves efficiency compared to manual operation and avoids material spillage.

[0019] The power drive components adopt a complementary power supply mode of solar energy, wind energy and blade batteries, which reduces operating costs and produces zero emissions compared to fuel-powered equipment. Attached Figure Description

[0026] The following is in conjunction with the appendix Figures 1-5 The present invention will be described in further detail below.

[0027] Example 1 This invention discloses a small boat for cleaning up blue-green algae. (See reference...) Figure 1 The small boat comprises a hull 1, a support frame 2, a cleaning assembly 3, a dumping and collection tank 4, and a power supply drive assembly 7. The boat consists of two buoyant bodies 11 to enhance buoyancy and stability. The support frame 2, located inside the hull 1, provides a support area for mounting the cleaning assembly 3 and other related components. The cleaning assembly 3, situated above the support frame 2, cleans and transports algae contaminants. The dumping and collection tank 4, located at the end of the cleaning assembly 3, receives and stores the cleaned and transported algae contaminants. The power supply drive assembly 7 provides power to the assembly, supporting its operation. The small boat first travels to a predetermined location using a built-in navigation system for precise positioning. Upon reaching the target area, the cleaning assembly 3 begins operation, removing blue-green algae from the water surface and transporting it to the dumping and collection tank 4 via a cutting and conveying mechanism. The cleaned algae is then directly fed into the collection tank via a conveying device, completing the contaminant collection process.

[0028] like Figure 5 As shown, the hull 1 includes a suspension body 11 and a connecting frame 411 body 12. The cavity within the suspension body 11 provides buoyancy through air inflation. This allows the hull 1 to adapt to varying water depths while maintaining stability and load-bearing capacity on the water surface. By filling with air, the buoyancy of the suspension body 11 is increased, ensuring sufficient support during operation and preventing it from sinking due to excessive load. The air filling material can be adjusted as needed to adapt to different working environments. The connecting frame 411 body 12 is located inside the suspension body 11 and serves as the connector between the suspension body 11 and the supporting frame 2, ensuring the connection performance between the supporting frame 2 and the hull 1. The connection between the connecting frame 411 body 12 and the supporting frame 2 maintains the integrity of the hull 1. The suspension body 11 provides sufficient buoyancy.

[0029] like Figure 2 As shown, the cleaning component 3 consists of a conveying structure 5 and a cutting structure 6. The conveying structure 5 is set at a predetermined angle, allowing floating algae to flow smoothly from the collection direction to the dumping collection box 4. This prevents algae from accumulating or clogging during transport. The conveying structure 5 transports the collected algae contaminants from the cleaning area to the collection box. The cutting structure 6 is fixed to the end of the conveying structure 5 away from the dumping collection box 4, ensuring that the algae are cut into smaller fragments after collection before being introduced into the conveying structure 5 for further processing. This makes the cleaning process more efficient and avoids large pieces of floating algae clogging the conveying path. The cutting structure 6 breaks up algae clumps, cutting floating cyanobacteria into smaller parts, thereby reducing the risk of algae clogging the conveying structure 5. The cut algae are guided to the conveying structure 5, ensuring that the cut algae can smoothly enter the conveying system without causing blockage.

[0030] In actual use, the cutting structure 6 cuts the floating algae and guides it into the conveying structure 5. After being processed by the conveying structure 5, the algae is sent into the dumping collection box 4, completing the cleaning and collection process. The cutting structure 6 breaks down the algae into fragments, preventing the conveying structure 5 from being clogged by large pieces of algae and ensuring continuous and efficient operation of the equipment. Through a predetermined angle and smooth conveying design, a large amount of algae can be collected and transferred to the collection box in a short time, thereby improving overall cleaning efficiency.

[0031] like Figure 3As shown, the cutting structure 6 includes a connecting bracket 61, a guide frame 62, a cutting bracket 63, and a cutting blade 64. The connecting bracket 61 is fixed to the conveying structure 5 to ensure stable operation of the entire cutting device. The position and angle of the guide frame 62 are adjustable, allowing for adaptation to different algae morphologies and cutting requirements. Since algae species and densities may vary, adjusting the angle of the guide frame 62 helps the cutting blade 64 cut algae more precisely, ensuring higher efficiency. The guide frame 62 is installed inside the connecting bracket 61, and the cutting bracket 63 provides a stable mounting platform 73 for the cutting blade 64. The cutting blade 64 rotates on the bracket, which possesses sufficient strength and stability to prevent displacement or loosening during operation. The cutting bracket 63 is fixed to the outside of the connecting bracket 61, ensuring the cutting device's position does not shift. This makes the cutting blade 64 rotate more smoothly. The cutting blade 64 and the cutting bracket 63 are rotatably connected via a shaft, allowing the blade to rotate freely in the water for efficient algae cutting. The rotating connection ensures the blades can move flexibly and continuously during operation to cut algae. In actual use, the cutting blades 64 are driven by a motor. The end of the guide frame near the cutting blades 64 is matched with the movement trajectory of the blades, ensuring that the cutting blades 64 can cut algae smoothly without any obstruction. The guide frame 62 provides a suitable guiding path for the cutting blades 64. The design of the guide frame 62 can effectively guide the movement of the cutting blades 64, ensuring cutting accuracy and efficiency. The guide frame 62 adopts a suitable curved shape that matches the rotation path of the cutting blades 64, thereby ensuring that floating algae during the cutting process can be accurately cut and guided to the conveying structure 5.

[0032] like Figure 3As shown, the conveying structure 5 includes: a conveying positioning frame 51, a conveyor belt 52, conveying baffles 53, a main drive bearing wheel 54, a driven support frame 55, and a driven roller 56. The conveying positioning frame 51 is the support frame of the entire conveying system, used to fix and stabilize the conveyor belt 52 and other components, ensuring that the conveyor belt 52 moves along a predetermined track without deviation. The conveyor belt 52 is located inside the conveying positioning frame 51 and is responsible for conveying floating algae from the collection area to the dumping collection box 4. Multiple conveying baffles 53 are evenly spaced on the conveyor belt 52. The function of the baffles is to prevent floating algae from slipping or scattering during the conveying process. Through effective material blocking, the baffles can ensure that the algae always stays on the conveyor belt 52 and help control the movement speed and direction of the algae; the conveying baffles 53 help increase the load-bearing capacity of the conveyor belt 52 and the stability of the material, ensuring that floating algae do not tilt, tip over, or accumulate during the conveying process. The main drive bearing wheel 54 is located at one end inside the conveyor belt 52, providing the driving force required for the movement of the conveyor belt 52. The main drive bearing wheel 54 generates power through contact with the conveyor belt 52, propelling the conveyor belt 52 forward. The driven support frame 55, connected to the conveyor positioning frame 51, supports and stabilizes the conveyor belt 52. The driven support frame 55 primarily maintains the tension of the conveyor belt 52, preventing excessive slack or deformation, and provides support for the driven roller shaft 56, ensuring smooth operation of the conveyor belt 52. The driven roller shaft 56 is rotatably connected to the driven support frame 55, supporting the conveyor belt 52 and assisting in power transmission. Through rotation, the roller shaft maintains the stability of the conveyor belt 52, preventing excessive slack or jamming. The driven roller shaft 56 not only provides support for the conveyor belt 52 but also coordinates with the operation of the main drive bearing wheel 54 to ensure the stability of the entire conveying system. When the main drive bearing wheel 54 propels the conveyor belt 52, the driven roller shaft 56 assists in its smooth operation.

[0033] like Figure 4As shown, the dumping collection box 4 includes: a dumping support base 41, a connecting frame 411, a groove 412, a detection component 413, a dumping box body 42, a sliding support frame 43, and a dumping bracket 44. The dumping support base 41 is located at one end in the output direction of the cleaning component 3 and is fixed to the support frame 2. It provides a stable foundation support for the dumping box body 42, ensuring that the entire dumping collection box 4 remains stable during dumping. The support base acts as a support platform, bearing the weight of the dumping box body 42 and assisting in transmitting the force generated when the box is dumped. The dumping box body 42 is mounted on the dumping support base 41 and supported by a rotating connection. The dumping box body 42 is responsible for receiving the algae output by the cleaning component 3 and dumping the material into the collection area after the cleaning process. When it is necessary to empty the material in the box, the dumping box body 42 will tilt to one side by rotating, dumping the internal material out. The rotating connection allows the dumping box body 42 to tilt at a certain angle, ensuring that the material can be completely discharged. Sliding support frames 43 are located on both sides of the tilting box 42 and have sliding grooves. Their function is to provide support for the tilting box 42 and guide it during tilting. The sliding support frames 43 not only support the tilting box 42 but also provide a sliding track for the tilting bracket 44, ensuring the tilting box 42 can tilt smoothly while reducing friction and resistance. One end of the tilting bracket 44 is slidably connected to the sliding support frame 43, and the other end is rotatably connected to the tilting box 42. The tilting bracket 44 is mainly responsible for tilting the tilting box 42. When the tilting box 42 needs to be tilted, the tilting bracket 44 slides along the sliding support frame 43, causing the box to rotate and gradually tilt. This combination of sliding and rotation helps to achieve a smooth and precise tilting action. During the tilting process, the tilting bracket 44 slides along the sliding support frame 43, and the angle of the sliding support frame 43 also changes. This ensures that the tilting angle of the tilting box 42 can be gradually adjusted to adapt to different tilting volumes and material characteristics. As the tilting container 42 gradually tilts, the changing angle of the sliding support frame 43 allows for more stable and precise tilting. Adjusting the angle also helps prevent uneven or excessively rapid material flow during tilting, thus reducing spillage or waste.

[0034] like Figure 2As shown, in the above embodiment, the tilting support base 41 further includes: a connecting frame 411, a groove 412, and a detection component 413. The tilting support base 41 and the connecting frame 411 are integrally formed to ensure the strength and stability of the structure. The tilting support base 41 provides a stable support for the tilting collection box 4, bears the weight of the tilting box body 42, and provides a stable foundation for the rotation of the tilting box body 42. The connecting frame 411 provides a rotational connection area for the tilting collection box 4. The tilting box body 42 needs to complete the tilting action by rotating. The connecting frame 411 is responsible for connecting with the rotating parts of the tilting box body 42 to ensure that the tilting box body 42 can tilt smoothly and stably. The groove 412 opened on the connecting frame 411 provides a dedicated area for component installation. The groove 412 design ensures that the component can be firmly installed on it, avoiding loosening or displacement during operation. The area is specifically designed for installing other components that need to be fixed to the connecting bracket 411. The detection component 413 is fixed inside the groove 412 to ensure its stability during the tilting process. The detection component 413 includes an infrared sensor camera, which collects data inside the tilting box 42.

[0035] like Figure 2 As shown, the power supply drive assembly 7 includes: a mounting frame 71, a drive motor 72, a mounting platform 73, and a power supply unit. The mounting frame 71 is connected to the support frame 2 and is erected above the cleaning assembly 3, providing support and positioning functions. The mounting frame 71 provides structural support for the entire power supply drive assembly 7, ensuring that its various components can be stably installed and operated. The drive motor 72 is fixed to the mounting frame 71 and provides the power required for the operation of the conveying structure 5. The drive motor 72 is one of the core components of the power supply drive assembly 7, and is connected to the conveying structure 5 via a transmission belt and a transmission gear disc. The mounting platform 73 is located at the upper end of the mounting frame 71, providing installation space for the power supply unit and ensuring its stable placement. The power supply unit provides the necessary power support for the overall drive of the equipment.

[0036] like Figure 2As shown, in the above embodiment, the power supply unit further includes: a solar panel 74, a battery module 75, and a wind power generation structure 76. The solar panel 74 converts sunlight into electrical energy to provide power to the system. The solar panel 74 utilizes the photovoltaic effect to convert light energy into direct current. The solar panel 74 works in conjunction with a photovoltaic inverter for conversion, and the angle of the solar panel 74 is adjustable to meet usage requirements. The battery module 75 stores the electrical energy generated by the solar panel 74 and the wind power generation structure 76 for use by the equipment when there is insufficient sunlight or wind. The battery module 75 can store the converted electrical energy, ensuring that the power supply system provides stable power when needed. In this embodiment, a blade battery is used. The "blade battery" uses lithium iron phosphate technology, which can skip the "module" stage when assembled, greatly improving the volume utilization rate and ultimately achieving the goal of installing more battery cells in the same space. The wind power generation structure 76 is another important component of the power supply unit, converting wind energy into electrical energy. Wind power generation uses wind to drive the wind turbine blades to rotate, thereby driving the generator to generate electricity. The wind power generation structure 76 can supplement the solar panels 74. When the solar panels 74 cannot meet the power demand, the wind power generation structure 76 can provide a stable power supply through wind energy, especially in the absence of sunlight. The solar panels 74, battery components 75, and wind power generation structure 76 together constitute a complementary energy system. When there is sufficient sunlight, the solar panels 74 provide power to the system; when there is wind, the wind power generation structure 76 supplements the power. The battery components 75 are responsible for storing excess electrical energy, ensuring that the system can still operate stably when sunlight and wind conditions are poor.

[0037] like Figure 4 As shown, a power structure 8 is also provided at the end of the dumping collection box 4. The power structure 8 includes a propeller 81 and a spiral propulsion blade 82. The propeller is fixed to both sides of the lower end of the dumping collection box 4, and the angle of the propeller is adjustable. The propeller 81 provides the power required for the rotation of the spiral propulsion blade 82. By adjusting the angle of the propeller, the working angle of the spiral propulsion blade can be changed, thereby optimizing its propulsion effect. It can be adjusted according to different working conditions, such as the type and quantity of materials and the tilt angle of the dumping collection box 4. The adjustable angle of the propeller can be dynamically adjusted according to actual needs, so that the power structure 8 can operate efficiently under different working conditions, avoiding inefficiency or power waste caused by unsuitable angles.

[0038] Example 2 Based on Example 1, a method for cleaning cyanobacteria using a small boat is proposed, comprising the following steps: S1. Start the power supply drive component 7. The solar panel 74 and the wind power generation structure 76 start to supply power in coordination. The blade battery 75 enters the standby state. The remaining capacity of the dumping collection box 4 is checked by the infrared sensor camera (detection component 413) to ensure that the box is empty.

[0039] S2. The built-in navigation system is activated. The small boat is supported by two suspension bodies 11. The propeller 81 of the power structure 8 (angle adjusted to 0°) drives the propeller blades 82 to sail to the cyanobacteria accumulation area at a speed of 8 km / h with a positioning accuracy of ≤10m.

[0040] S3. Adjust the angle of the guide frame 62 (adjust to 15°-30° according to the algae density), start the drive motor of the cutting blade 64 (speed 3000r / min), the blade rotates at high speed with YG8 hard alloy material, cut the blue-green algae clumps on the water surface into 5-10cm fragments; the main drive bearing wheel 54 drives the conveyor belt 52 to run at a speed of 0.3m / s, the conveyor baffle 53 (height 5cm) prevents the algae fragments from slipping, the conveyor belt tilted at 25°-30° guides the cut blue-green algae from the cleaning area to the collection box 4; the driven support frame 55 and the driven roller shaft 56 maintain the tension of the conveyor belt to avoid slippage or accumulation, and ensure that the hourly conveying capacity is ≥500L.

[0041] S4. Blue-green algae fragments fall into the dumping box 42 via the end of the conveyor belt 52. The infrared sensor camera of the detection component 413 monitors the filling level in real time. When the filling rate of the box is detected to be ≥80%, a signal is sent to the control system, and the dumping operation is initiated. The dumping bracket 44 slides along the groove of the sliding support frame 43, causing the dumping box 42 to tilt at 45°. The blue-green algae inside is dumped to the shore collection point or transport ship by gravity. The dumping time is ≤15 seconds. After dumping is completed, the box is reset, the detection component confirms the empty box status, and the collection cycle continues.

[0042] S5. When the operating area needs to be changed, the angle of the thruster 81 can be adjusted to ±15°, and the rotation speed of the propeller blades 82 can be increased to 1500r / min. The boat's steering accuracy is ≤5°, adapting to complex water terrain. When there is sufficient sunshine, the solar panel 74 (power 100W) provides priority power supply, and excess energy is stored in the battery shear 75 (blade battery) (capacity 10kWh). When the wind force is ≥3, the wind power generation structure 76 is activated to ensure continuous operation of the system for ≥8 hours.

[0043] S6. Close the cutting structure 6 and the conveying structure 5, remove the conveying baffle 53 to clean residual algae, check the wear of the cutting blades 64 (allowable blade wear ≤0.5mm), and replenish the air pressure of the inflatable suspension body 11 to 0.2MPa. The small boat returns to the mooring area, the angle of the solar panel 74 is adjusted to be perpendicular to the direction of sunlight, the blade battery 75 is charged to more than 90%, and the system enters low-power standby mode to prepare for the next operation.

[0044] Example 3 Based on Embodiments 1 and 2, when selecting the conveyor belt drive motor 72, the maximum angle of the conveyor belt slope is set to 25 to 30 degrees, and the boat moves in uniform linear motion on the conveyor belt with a maximum speed of v = 0.3 m / s. The total mass of the boat is m = 100 KG, the transmission efficiency is l = 0.9, the inertial force of the conveyor belt is ignored, and the total power required for the boat's motion is P = 200 W.

[0045] The selection of conveyor belts requires consideration of multiple factors, including material characteristics, transportation needs, and the operating environment. Given the unique environment of Dianchi Lake and the pollutants that need to be treated, conventional materials such as rubber and polypropylene are insufficient. Therefore, we chose polyurethane as the material for the conveyor belt. Compared to other conventional conveyor belt materials, polyurethane has advantages such as corrosion resistance, water resistance, durability, and environmental friendliness, making it better suited to the working environment of Dianchi Lake. Traditional conveyor belts struggle to operate long-term on water, while the conveyor belts on small boats can guarantee long-term, high-quality operation on the water. To meet the levitation requirements of the hull 1, an air-filled cavity is installed inside the suspension body 11. Buoyancy is adjusted by adding an air pump and a gas sensor, so that the small boat can remain stable in different water depths and currents.
