Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology and relates to a device for collecting suspended solids on the surface of water bodies for wastewater treatment. Background Technology

[0002] In today's society, with the acceleration of industrialization and the continuous growth of the population, wastewater treatment has become a crucial link in the field of environmental protection. Water pollution not only threatens the ecological balance but also has a profound impact on human health and quality of life. Among them, suspended solids on the surface of water bodies, as one of the common pollutants in wastewater, play an indispensable role in improving wastewater treatment efficiency and water quality through effective collection and treatment.

[0003] Suspended matter on the surface of water bodies typically includes various substances such as floating plastic fragments, leaves, algae, microbial aggregates, and other organic and inorganic particles. The presence of these suspended particles can cause a series of problems. First, they affect the appearance of the water body, making it turbid and dirty, reducing its aesthetic value. This effect is particularly pronounced in urban landscape water bodies and tourist area waters, severely damaging the beauty and comfort of the surrounding environment.

[0004] Secondly, a large amount of suspended matter will hinder sunlight from penetrating the water, affecting the photosynthesis of aquatic plants and thus disrupting the balance of the aquatic ecosystem. Insufficient light will prevent phytoplankton such as algae from photosynthesizing properly, leading to a decrease in dissolved oxygen levels in the water, affecting the survival of aquatic organisms, causing the death of fish and other aquatic animals, and further disrupting the entire aquatic food chain.

[0005] Furthermore, suspended solids often adsorb large amounts of pollutants such as heavy metal ions, pesticide residues, and chemical oxygen demand (COD). These substances can spread as the suspended solids migrate in the water, increasing the scope of water pollution and the difficulty of treatment. If discharged directly without effective treatment, it will cause serious secondary pollution to the receiving water body, harming the surrounding soil, groundwater, and crop growth.

[0006] Currently, common methods and devices for collecting suspended solids on the surface of water bodies have many limitations. Traditional manual dredging methods, while effective in small bodies of water or when the concentration of suspended solids is low, are extremely inefficient and require significant manpower and time. Moreover, manual dredging cannot guarantee the complete removal of suspended solids, easily overlooking some fine particles and hard-to-reach areas, resulting in inconsistent dredging effectiveness.

[0007] Some simple mechanical retrieval devices, such as those using fixed grids or filters, while improving retrieval efficiency to some extent, suffer from poor flexibility. Once the grid spacing or filter aperture is determined, these devices can only intercept suspended debris of a specific size, often proving ineffective against debris that is too small or too large. Furthermore, fixed grids and filters are easily clogged by suspended debris, requiring frequent cleaning; otherwise, the collection effect will be severely compromised, and the entire device may even malfunction. Utility Model Content

[0008] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a water surface suspended solids collection device for sewage treatment. The collection device provided by this utility model does not require additional water platform or complex support structure, and can operate directly on the water surface, which greatly improves the flexibility and ease of use of the device, realizes automatic collection of floating impurities on the water surface, improves the cleaning efficiency of floating debris on the water surface, and reduces the intensity of manual labor.

[0009] To achieve this objective, the present invention adopts the following technical solution:

[0010] This utility model provides a device for collecting surface suspended solids in wastewater for sewage treatment. The device includes a collection box and four collection components located on the outer periphery of the collection box. Adjacent collection components are perpendicular to each other and connected by a flexible connector. The flexible connector is equipped with an air bladder so that the device floats on the water surface.

[0011] The collection assembly includes a collection housing that is fixedly connected to the outer wall of the collection box and communicates with the interior of the collection box. A conveying component is disposed inside the collection housing, and the conveying component conveys the debris toward the collection box. A hook-shaped component is disposed at one end of the collection housing away from the collection box. The hook-shaped component is used to hook up debris floating on the water surface and transfer it to the conveying component, which then transfers the debris to the collection box.

[0012] This invention provides a collection device for automatically collecting floating debris on the water surface. In use, after inflating the air bladder, the collection device is placed in the water. The device floats on the surface under the action of the air bladder. A propeller drives the entire collection device to move. During movement, a hook inside the collection housing hooks the floating debris into the housing. The debris inside the housing is then conveyed to a collection box by a conveyor. Compared to traditional manual or partially mechanical salvage devices, this invention eliminates the need for additional floating platforms or complex support structures, allowing for direct operation on the water surface. It automatically collects floating debris, improving the efficiency of cleaning floating debris, reducing manual labor intensity, and significantly enhancing the device's flexibility and ease of use.

[0013] The collection assembly includes a collection shell connected to a collection box, inside which a conveyor is configured to transport debris towards the collection box, and a hook is located at the end furthest from the collection box. In use, as the collection device moves across the water surface, the hook actively catches floating debris and quickly transports it to the collection box via the conveyor. This automated collection process significantly improves efficiency. Traditional manual retrieval relies on manual labor to collect debris one by one, which is slow and labor-intensive. Some simple mechanical retrieval devices are limited by the spacing of the grid or the mesh size of the filter, resulting in poor collection of debris of different sizes. In contrast, the hook and conveyor of the collection device provided by this invention work together to continuously and efficiently collect various types of floating debris, effectively solving the problem of low efficiency in traditional methods.

[0014] This invention connects two adjacent collection components with a flexible connector (this invention does not specify or limit the type of flexible connector, such as a rope), so that a limiting area is formed between the flexible connector and the collection components to temporarily restrict the movement of floating debris. During the movement of the collection device, the debris floating on the water surface is intercepted by the flexible connector and collected around the collection device. The collected floating debris is then hooked into the conveyor by the hook, realizing the rapid cleaning of floating debris, improving collection efficiency, avoiding manual retrieval operations, reducing the labor intensity of manual labor, and saving labor costs.

[0015] Traditional manual dredging requires a large workforce and long hours of work, which is physically demanding and the working environment is harsh. This invention sets up multiple collection components connected to the collection box on the outside of the collection box. Each collection component faces a different direction, and a propeller is set at the bottom of each collection shell. Operators only need to remotely control the propeller and other equipment to monitor the operation of the device, which greatly reduces the degree of manual involvement, reduces labor intensity, and saves labor costs. At the same time, it avoids operators from direct contact with sewage, reducing the risk of health threats to operators from contact with harmful substances in sewage.

[0016] The collection device provided by this utility model also possesses excellent environmental adaptability. Multiple collection components are arranged around the outer periphery of the collection box, each facing a different direction. The movement mode and trajectory of the collection device can be flexibly adjusted according to the distribution of floating debris by changing the direction of the propellers and their activation / deactivation. For example, when the floating debris is distributed regularly and relatively concentrated, only one or a few propellers can be activated, causing the collection device to move linearly or curvilinearly in a certain direction to collect debris gathered in a single direction. When the floating debris is irregularly distributed and relatively scattered, all propellers can be activated simultaneously. By controlling the direction of the propellers, the collection device rotates in place, creating a vortex in the water. The floating debris is drawn towards the collection device by the vortex, indirectly expanding the collection area. Therefore, the collection device provided by this utility model can change its movement mode according to the position and size of the debris to adapt to different distribution states, improving the adaptability and efficiency of the collection device.

[0017] As a preferred technical solution of this utility model, the collecting shell is a square cross-section tubular structure with open ends, which is composed of two fixed side plates, a fixed bottom plate and a fixed top plate. The fixed bottom plate is provided with a number of water leakage holes.

[0018] The collection housing provided by this utility model is composed of two fixed side plates, a fixed bottom plate, and a fixed top plate. Compared to other shapes, the square structure is more stable and distributes stress more evenly, better able to withstand the impact of water flow and various external forces generated during collection. This stable structure helps ensure the collection device functions properly in complex aquatic environments, reducing malfunctions caused by structural instability. Simultaneously, the combination of the fixed side plates, fixed bottom plate, and fixed top plate creates a relatively enclosed space inside the collection housing, facilitating the guidance of debris collection paths and allowing debris to smoothly enter the collection box via the conveyor, preventing debris from escaping during collection and improving collection efficiency and integrity.

[0019] This invention features several drainage holes on the fixed base plate of the collection housing, enabling preliminary filtration. During the movement of the collection device, water and floating debris simultaneously enter the collection housing. The debris is hooked by the hook and fed into the conveyor belt, while the water carried by the debris flows out through the drainage holes. This design effectively prevents large amounts of water from entering the collection tank along with the debris, reducing the workload of subsequent processing. Without these drainage holes, a large amount of water would accumulate in the collection tank, increasing its weight and affecting the stability and operating efficiency of the collection device, placing greater pressure on subsequent processing equipment and reducing processing efficiency.

[0020] As a preferred technical solution of this utility model, a propeller is fixed on the outer side of the bottom surface of the fixed base plate of each collection shell, and the propeller is used to push the water surface suspended matter collection device to move on the water surface.

[0021] In this invention, the propeller enables the collection device to move autonomously, overcoming the limitations of traditional fixed collection devices. Common fixed grilles or filters can only intercept floating debris in a fixed location, covering a limited area. However, the collection device provided by this invention, thanks to its propeller, can actively move towards areas where debris accumulates. When an increase in floating debris is detected in a specific area of ​​the water surface, the device can quickly adjust its position to collect it, greatly expanding the cleaning range. Taking a park's landscape lake as an example, the location of fallen leaves varies with the season; the collection device provided by this invention can flexibly move and collect them accordingly, avoiding the hassle of manually moving equipment and significantly improving cleaning efficiency.

[0022] This invention, by incorporating multiple propellers, allows the collection device to better adapt to complex environments. Since the distribution of floating debris on the water surface is complex and varied, when the debris is distributed in a regular and concentrated manner, activating only one or some propellers allows the collection device to move in a straight line or curve in a specific direction, accurately collecting the floating debris in that area, reducing energy waste and improving collection targeting. If the debris is distributed irregularly and scattered, activating all propellers simultaneously and controlling the propulsion direction allows the collection device to rotate in place, forming a vortex in the water. Under the influence of the vortex, the originally scattered floating debris will move closer to the collection device, indirectly expanding the collection area and achieving efficient cleaning of scattered floating debris. This fully demonstrates the adaptability of the collection device to different debris floating distribution states.

[0023] In this invention, adjacent collection components are connected by flexible connectors to form a limiting area. As the propeller moves the collection device, floating debris on the water surface is intercepted by the flexible connectors and collected around the collection device. At this time, the propeller continuously provides power to keep the collection device moving, ensuring that floating debris is continuously intercepted and collected. The hook can more efficiently hook the debris into the conveyor, achieving rapid cleaning, further improving collection efficiency and reducing manual labor intensity.

[0024] In this invention, the propeller works in conjunction with other components of the collection device to ensure stable overall operation. The conveyor is responsible for transporting the hooked debris to the collection tank. During the propeller's movement, it continuously provides the conveyor with a new source of floating debris, maintaining the continuity of the conveying operation. The level detector monitors the water level. When the debris collected in the collection tank increases, causing the collection device to sink, it controls the inflation of the airbag to adjust buoyancy. The propeller's movement also helps the level detector to detect changes in the water level in a timely manner. The three components work together to ensure stable operation of the collection device under different working conditions, continuously and efficiently collecting floating debris from the water surface.

[0025] As a preferred technical solution of this utility model, the conveying member is inclinedly disposed inside the collection shell. The conveying member has a feeding end and a discharging end. The feeding end is close to the hook member, and the discharging end extends into the inside of the collection box. The feeding end is lower than the discharging end. Debris floating on the water surface is conveyed from the feeding end to the discharging end and falls into the collection box from the discharging end.

[0026] In separating water and debris, the inclined conveyor can be highly effective. During the collection of suspended debris from the water surface, a significant amount of water inevitably mixes into the collection housing. If the conveyor is horizontal, this water, carried by the debris, is likely to be sent to the collection box along with the debris. If a large amount of water is mixed in the collection box, over time, the collected debris will ferment, deteriorate, and breed bacteria, causing secondary pollution to the surrounding environment. The inclined conveyor in this invention allows the water remaining on the conveyor belt to flow naturally down the inclined conveyor belt under gravity, effectively separating water and debris. This ensures that only the debris to be processed enters the collection box, reducing the water content and lowering the difficulty and cost of subsequent processing. Simultaneously, the friction between the debris and the conveyor belt ensures that the debris is stably conveyed to the collection box without slipping down the conveyor belt, guaranteeing the normal operation of the collection process.

[0027] As a preferred technical solution of this utility model, the conveying component includes a driving roller, a driven roller, a conveyor belt, and a driving component. The conveyor belt is wound around the outer periphery of the driving roller and the driven roller. The driving component is externally connected to the driving roller and is used to drive the driving roller to rotate. The driving roller is close to the hook component.

[0028] The structural design of the conveyor provided by this utility model offers a stable and efficient power source for conveying debris. The drive component rotates the active roller, which in turn causes the conveyor belt surrounding the active and driven rollers to rotate, thus conveying the debris. The drive component can be precisely adjusted according to actual needs. For example, in areas with a large amount of floating debris and greater collection difficulty, the output power of the drive component can be increased to raise the rotational speed of the active roller, thereby accelerating the conveyor belt's running speed and improving collection efficiency. Conversely, in areas with relatively less floating debris, the output power of the drive component can be appropriately reduced to save energy. This flexible power control method allows the collection device to adapt to different working scenarios, effectively improving its practicality and economy.

[0029] This invention positions the drive roller closer to the hook, allowing it to quickly reach the high-speed conveyor belt after the hook catches floating debris. Because the drive roller is close to the hook, the conveyor belt has a higher linear velocity at the feeding end, enabling it to quickly grab debris and stably transport it to the collection box. This design effectively reduces the time debris spends in the collection shell, preventing it from slipping or accumulating due to water flow fluctuations or its own weight, thus improving the success rate and continuity of collection.

[0030] As a preferred technical solution of this utility model, the hook-taking component includes a rotating shaft and a plurality of collecting hooks. The axial direction of the rotating shaft is perpendicular to the direction of water flow. The two ends of the rotating shaft are respectively movably fixed to the two fixed side plates. Bearings are provided at the connection between the two ends of the rotating shaft and the fixed side plates, and the two ends of the rotating shaft rotate within the bearings.

[0031] The collecting hook has an L-shaped structure, with one end fixed to the outer wall of the rotating shaft, and several collecting hooks are staggered along the circumference of the outer wall of the rotating shaft.

[0032] In this invention, the collecting hooks are L-shaped and staggered along the outer wall of the rotating shaft, greatly increasing the contact area and hooking probability with floating debris on the water surface. When the collecting device moves, the rotating shaft drives the collecting hooks to rotate. The staggered L-shaped hooks, with their unique shape and distribution, can effectively hook different types of floating debris, significantly improving collection efficiency compared to ordinary flat or single-structure collecting tools.

[0033] As a preferred technical solution of this utility model, a transmission wheel is respectively provided at both ends of the rotating shaft. The transmission wheels at both ends of the rotating shaft are connected to the two ends of the drive roller via belt drive. The drive roller drives the conveyor belt to rotate while driving the rotating shaft to rotate through the belt and the transmission wheel.

[0034] This invention connects the drive wheels at both ends of the rotating shaft to the two ends of the drive roller via belt drive. This ingenious transmission connection transfers the power of the drive roller to the rotating shaft, allowing the hook and conveyor to work in tandem, playing a crucial role in improving the performance of the entire collection device. This design ensures stable and synchronized operation of the hook and conveyor. By connecting the drive roller and rotating shaft via belt drive, when the drive roller rotates stably under the drive of the driving component, the rotating shaft rotates synchronously and stably thanks to the belt drive. Because the rotating shaft and drive roller rotate synchronously, the rotational speed of the hook and the conveyor speed of the belt can be precisely matched. After the hook quickly catches floating debris, the synchronously moving conveyor quickly transports the debris to the collection box. This efficient coordination greatly increases the amount of debris the collection device can process per unit time. If the hook and conveyor are not synchronized, it will lead to low collection efficiency, or even debris accumulation and blockage of the collection device.

[0035] Furthermore, this design effectively reduces the equipment's energy consumption and maintenance costs by simultaneously transmitting the power of the drive roller to both the conveyor belt and the rotating shaft, eliminating the need for a separate drive unit for the rotating shaft and reducing the number of components and energy consumption. Fewer components mean a lower probability of failure and lower maintenance costs. During equipment operation, there is no need to invest a large amount of energy and manpower to maintain multiple drive units, thus improving the overall economic efficiency of the equipment.

[0036] As a preferred technical solution of this utility model, the collection box is a box body composed of a collection top plate, four collection side plates and a collection bottom plate. The edge of the collection top plate is hinged to the edge of any of the collection side plates to realize the flip-opening of the collection top plate. A transparent observation window is embedded in the collection top plate.

[0037] In this invention, the top and side collection plates are hinged and can be flipped open, greatly facilitating the cleaning and maintenance of the collection tank. In actual wastewater treatment processes, a large amount of debris accumulates inside the collection tank. Prolonged accumulation can lead to odors, bacterial growth, and even affect the normal operation of the equipment. By flipping open the top collection plate, workers can easily access the inside of the collection tank to thoroughly clean every corner, ensuring the collection tank remains in good working condition. Furthermore, this design facilitates the inspection, repair, or replacement of components inside the collection tank, such as cleaning potentially clogged discharge ends of the conveyor components or checking the bottom of the collection tank for damage, effectively extending the equipment's service life and reducing maintenance costs.

[0038] The design of the top cover helps improve the safety and sealing of the entire collection device. During operation, the closed top cover prevents collected debris from splashing out, avoiding pollution and harm to the surrounding environment and personnel. At the same time, good sealing also reduces odor emissions, minimizing the impact on the surrounding air environment and creating a more comfortable working environment for operators.

[0039] A transparent observation window is embedded in the top plate of the collection tank, allowing operators to monitor the debris collection process in real time without frequently opening the top plate. This serves two purposes: firstly, it helps operators track the collection progress and determine if the tank is nearing its capacity. When the tank is about to reach its limit, timely cleaning can be arranged to prevent overflow and ensure effective collection and protect the aquatic environment. Secondly, the observation window allows operators to view the type and condition of the collected debris. If any unusual substances are found, such as large amounts of chemical waste or unknown pollutants, appropriate measures can be taken promptly to adjust subsequent treatment procedures, ensuring the quality and safety of wastewater treatment.

[0040] As a preferred technical solution of this utility model, each of the collecting side plates is provided with a material collection port communicating with the collecting shell, and the unloading end of the conveying component extends into the interior of the collecting box through the material collection port.

[0041] In this invention, the collection port enables seamless connection between the collection component and the collection box. The conveyor within the collection housing transports floating debris collected by the hook component, while the collection port serves as the crucial channel for the debris to enter the collection box. The discharge end of the conveyor extends into the collection box through the collection port, allowing debris to fall directly and smoothly from the conveyor into the collection box. This avoids potential drops or spills during transfer, ensuring the continuity and efficiency of the collection process.

[0042] Secondly, the rational design of the collection port effectively avoids the risk of secondary pollution during the collection process. Without a collection port, or with an unreasonable design, debris may come into contact with the external environment when entering the collection box, causing pollutants carried on the debris to leak into the surrounding water bodies. However, the collection port of this invention is tightly fitted with the unloading end of the conveyor, allowing debris to enter the collection box from the collection shell in a relatively enclosed environment, greatly reducing the possibility of pollutant leakage.

[0043] Secondly, the presence of the collection port facilitates the maintenance and cleaning of the collection device. When it is necessary to clean the collection box or collection components, the collection port provides an easy-to-operate channel. Workers can more easily inspect, clean and maintain the unloading end of the conveyor through the collection port, and it is also convenient to clean the area inside the collection box near the collection port.

[0044] As a preferred technical solution of this utility model, a liquid level detector is provided on the outer wall of the collection box, an air pump is connected to the air bladder, the liquid level detector is electrically connected to a controller, and the controller provides feedback control to the air pump. When the water level exceeds the liquid level detector, the liquid level detector sends a sensing signal to the controller. When the controller receives the sensing signal, it sends a control command to the air pump to inflate the air bladder.

[0045] During the collection of suspended debris from the water surface, as the amount of debris collected in the collection tank increases, the overall weight of the collection device gradually increases. Once the weight exceeds the buoyancy provided by the air bladder, the collection device will sink, affecting the collection effect and even causing the collection operation to fail. This invention, through the coordinated operation of a liquid level detector, a controller, and an air pump, can monitor the water level and the floating status of the collection device in real time. When the water level exceeds the liquid level detector, it indicates that the collection device may sink due to excessive debris. The liquid level detector sends a sensing signal to the controller, which then controls the air pump to inflate the air bladder, increasing its buoyancy and causing the collection device to float back to a suitable position, maintaining its position on the water surface for efficient collection operations, thus ensuring the continuity and stability of the collection work.

[0046] Furthermore, this design enables automated adjustment of the collection device, significantly improving its intelligence. It eliminates the need for constant manual monitoring of the device's buoyancy, reducing manual operation costs and human error. Operators only need to make simple settings before operation, and the device automatically adjusts the buoyancy of the airbags based on changes in water level, greatly enhancing its environmental adaptability.

[0047] It should be noted that the unloading end of the conveyor provided by this utility model should be located above the water level to ensure that the debris conveyed to the unloading end does not contain a large amount of water, which would cause a large amount of water to enter the collection tank and affect the overall weight of the collection device. Ideally, the hook part should be immersed in the water, while the entire conveyor should be located above the water surface.

[0048] The operation process of the water surface suspended solids collection device provided by this utility model is as follows:

[0049] (1) Preparation: Before use, the operator should start the air pump connected to the airbag to fill the airbag with enough gas; at the same time, check whether the components of the collection device are securely connected, such as the connection between the collection shell and the collection box, the installation of the conveyor and hook components, etc., to ensure that the equipment is free of faults and that all components can operate normally; after confirming that everything is correct, place the collection device on the surface of the water body to be treated. At this time, the airbag provides buoyancy for the collection device, so that the entire collection device floats stably on the water surface, preparing for the subsequent collection of floating debris on the water surface.

[0050] (2) Device movement and debris collection: Start the propeller to provide power to the collection device and make it move on the water surface. If the debris floating on the water surface is distributed in a regular and concentrated manner, only some of the propellers need to be turned on, and the collection device can move in a straight line or curve in the set direction and accurately drive to the debris collection area. If the floating debris is distributed irregularly and scattered, all the propellers need to be turned on, and the collection device can be rotated in place by controlling the propulsion direction. During the movement of the collection device, the limiting area formed by the flexible connector between adjacent collection components plays a role. The flexible connector will intercept the debris floating on the water surface and make it collect around the collection device, which is convenient for subsequent collection operations.

[0051] (3) Debris hooking and conveying: When the collection device approaches the floating debris, the hooking and conveying components start to work, the driving component starts, and drives the active roller to rotate. The active roller drives the conveyor belt to rotate, and at the same time, it drives the rotating shaft and the collection hook on it to rotate through the belt and the drive wheel. During the rotation, the collection hook hooks the floating debris on the water surface from various angles. The hooked debris is transferred to the conveyor belt, and the debris moves along the conveyor belt from the loading end to the unloading end.

[0052] (4) Debris collection and box cleaning: After the debris moves to the unloading end with the conveyor belt, it falls into the collection box to complete the collection. The edge of the collection top plate is hinged to the collection side plate and can be flipped open to facilitate the cleaning of debris accumulated in the collection box. The transparent observation window embedded in the top plate allows the operator to observe the collection situation in the collection box in real time, such as the collection progress, the type and status of debris, so as to arrange the cleaning work in time and avoid the collection box being too full and causing debris to overflow.

[0053] (5) Device status monitoring and adjustment: The liquid level detector installed on the outer wall of the collection tank monitors the water level and the floating status of the device in real time. As the amount of debris collected in the collection tank increases, the overall weight of the collection device increases. When the water level exceeds the liquid level detector, the liquid level detector sends a sensing signal to the controller. After receiving the signal, the controller sends a control command to the air pump to inflate the air bag, increase the buoyancy of the air bag, prevent the collection device from sinking, and ensure that the feed end of the collection component is above the water surface, thus maintaining the normal working status of the collection device.

[0054] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0055] This invention provides a collection device for automatically collecting floating debris on the water surface. In use, after inflating the air bladder, the collection device is placed in the water. The device floats on the surface under the action of the air bladder. A propeller drives the entire collection device to move. During movement, a hook inside the collection housing hooks the floating debris into the housing. The debris inside the housing is then conveyed to a collection box by a conveyor. Compared to traditional manual or partially mechanical salvage devices, this invention eliminates the need for additional floating platforms or complex support structures, allowing for direct operation on the water surface. It automatically collects floating debris, improving the efficiency of cleaning floating debris, reducing manual labor intensity, and significantly enhancing the device's flexibility and ease of use.

[0056] The collection assembly includes a collection shell connected to a collection box, inside which a conveyor is configured to transport debris towards the collection box, and a hook is located at the end furthest from the collection box. In use, as the collection device moves across the water surface, the hook actively catches floating debris and quickly transports it to the collection box via the conveyor. This automated collection process significantly improves efficiency. Traditional manual retrieval relies on manual labor to collect debris one by one, which is slow and labor-intensive. Some simple mechanical retrieval devices are limited by the spacing of the grid or the mesh size of the filter, resulting in poor collection of debris of different sizes. In contrast, the hook and conveyor of the collection device provided by this invention work together to continuously and efficiently collect various types of floating debris, effectively solving the problem of low efficiency in traditional methods.

[0057] This invention connects two adjacent collection components with a flexible connector (this invention does not specify or limit the type of flexible connector, such as a rope), so that a limiting area is formed between the flexible connector and the collection components to temporarily restrict the movement of floating debris. During the movement of the collection device, the debris floating on the water surface is intercepted by the flexible connector and collected around the collection device. The collected floating debris is then hooked into the conveyor by the hook, realizing the rapid cleaning of floating debris, improving collection efficiency, avoiding manual retrieval operations, reducing the labor intensity of manual labor, and saving labor costs.

[0058] Traditional manual dredging requires a large workforce and long hours of work, which is physically demanding and the working environment is harsh. This invention sets up multiple collection components connected to the collection box on the outside of the collection box. Each collection component faces a different direction, and a propeller is set at the bottom of each collection shell. Operators only need to remotely control the propeller and other equipment to monitor the operation of the device, which greatly reduces the degree of manual involvement, reduces labor intensity, and saves labor costs. At the same time, it avoids operators from direct contact with sewage, reducing the risk of health threats to operators from contact with harmful substances in sewage.

[0059] The collection device provided by this utility model also possesses excellent environmental adaptability. Multiple collection components are arranged around the outer periphery of the collection box, each facing a different direction. The movement mode and trajectory of the collection device can be flexibly adjusted according to the distribution of floating debris by changing the direction of the propellers and their activation / deactivation. For example, when the floating debris is distributed regularly and relatively concentrated, only one or a few propellers can be activated, causing the collection device to move linearly or curvilinearly in a certain direction to collect debris gathered in a single direction. When the floating debris is irregularly distributed and relatively scattered, all propellers can be activated simultaneously. By controlling the direction of the propellers, the collection device rotates in place, creating a vortex in the water. The floating debris is drawn towards the collection device by the vortex, indirectly expanding the collection area. Therefore, the collection device provided by this utility model can change its movement mode according to the position and size of the debris to adapt to different distribution states, improving the adaptability and efficiency of the collection device.

[0069] In one specific embodiment, the present invention provides a device for collecting surface suspended solids in wastewater for sewage treatment, such as... Figure 1As shown, the water surface suspended solids collection device for sewage treatment includes a collection box 1 and four collection components 2 located on the outer periphery of the collection box 1; two adjacent collection components 2 are perpendicular to each other and connected by a flexible connector 3, and an airbag 4 is provided on the flexible connector 3 so that the water surface suspended solids collection device floats on the water surface.

[0070] exist Figure 1 and Figure 2 In the embodiment shown, the collection component 2 includes a collection housing 5 that is fixedly connected to the outer wall of the collection box 1 and communicates with the interior of the collection box 1. A conveying component 6 is disposed inside the collection housing 5, and the conveying component 6 conveys the debris towards the collection box 1. A hooking component 7 with a hook-like object is disposed at one end of the collection housing 5 away from the collection box 1. The hooking component 7 is used to hook up debris floating on the water surface and transfer it to the conveying component 6, which then transfers the debris to the collection box 1.

[0071] This invention provides a collection device for automatically collecting floating debris on the water surface. In use, the air bladder 4 is inflated, and the collection device is placed in the water. The device floats on the surface under the action of the air bladder 4. The propeller 12 drives the entire collection device to move. During this movement, the hook 7 inside the collection housing 5 hooks the floating debris into the collection housing 5. The debris inside the collection housing 5 is then conveyed to the collection box 1 by the conveyor 6. Compared to traditional manual or partially mechanical salvage devices, the collection device provided by this invention does not require an additional water platform or complex support structure. It can operate directly on the water surface, automatically collecting floating debris, improving the efficiency of cleaning floating debris, reducing manual labor intensity, and greatly enhancing the flexibility and ease of use of the device.

[0072] exist Figure 1 and Figure 2 In the illustrated embodiment, the collection component 2 includes a collection housing 5 connected to the collection box 1, with a conveying component 6 inside that moves towards the collection box 1, and a hook component 7 positioned at the end furthest from the collection box 1. During use, as the collection device moves across the water surface, the hook component 7 actively hooks up floating debris and quickly conveys it to the collection box 1 via the conveying component 6. This automated collection process significantly improves efficiency. Traditional manual retrieval relies on manual labor to collect debris one by one, which is slow and labor-intensive. Some simple mechanical retrieval devices are limited by the spacing of the grid or the mesh size, resulting in poor collection of debris of different sizes. In contrast, the hook component 7 and the conveying component 6 of the collection device provided by this invention work together to continuously and efficiently collect various types of floating debris, effectively solving the problem of low efficiency in traditional methods.

[0073] This invention connects two adjacent collection components 2 with a flexible connector 3 (this invention does not specify or limit the type of flexible connector 3, for example, it can be a rope), so that a limiting area is formed between the flexible connector 3 and the collection component 2 to temporarily restrict the movement of floating debris. During the movement of the collection device, the debris floating on the water surface is intercepted by the flexible connector 3 and collected around the collection device. The collected floating debris is hooked into the conveyor 6 by the hook 7, which realizes the rapid cleaning of floating debris, improves collection efficiency, avoids manual retrieval operations, reduces the labor intensity of manual labor, and saves labor costs.

[0074] Traditional manual dredging requires a large workforce and long hours of work, which is physically demanding and the working environment is harsh. This invention sets up multiple collection components 2 connected to the collection box 1 on the periphery of the collection box 1. Each collection component 2 faces a different direction. A thruster 12 is set at the bottom of each collection shell 5. Operators only need to remotely control the thruster 12 and other equipment to monitor the operation status of the device, which greatly reduces the degree of manual involvement, reduces labor intensity, and saves labor costs. At the same time, it avoids operators from directly contacting sewage, reducing the risk of health threats to operators from contact with harmful substances in sewage.

[0075] The collection device provided by this utility model also has good environmental adaptability. Multiple collection components 2 are arranged around the outer periphery of the collection box 1, each facing a different direction. The movement mode and trajectory of the collection device can be flexibly adjusted according to the distribution of floating debris by changing the propulsion direction and activation / deactivation of the propellers 12. For example, when the floating debris is distributed regularly and relatively concentrated, only one or several propellers 12 can be activated, causing the collection device to move linearly or curvilinearly in a certain direction to collect debris gathered in a single direction. When the floating debris is distributed irregularly and relatively scattered, all propellers 12 can be activated simultaneously. By controlling the propulsion direction of the propellers 12, the collection device rotates in place, thereby forming a vortex in the water. The floating debris on the water surface moves closer to the collection device under the influence of the vortex, thus indirectly expanding the collection area. Therefore, the collection device provided by this utility model can change its movement mode according to the position and size of the debris to adapt to different distribution states of the debris, improving the adaptability and efficiency of the collection device.

[0076] exist Figure 2 and Figure 3 In the embodiment shown, the collecting shell 5 is a square-section tubular structure with openings at both ends, consisting of two fixed side plates 8, a fixed bottom plate 9, and a fixed top plate 10. The fixed bottom plate 9 has several drainage holes 11 (e.g., ...). Figure 3 (As shown).

[0077] The collection housing 5 provided by this utility model is composed of two fixed side plates 8, a fixed bottom plate 9, and a fixed top plate 10. Compared with other shapes, the square structure is more stable and distributes stress more evenly, better able to withstand the impact of water flow and various external forces generated during collection. This stable structure helps ensure that the collection device works normally in complex aquatic environments, reducing malfunctions caused by structural instability. At the same time, the combination of the fixed side plates 8, fixed bottom plate 9, and fixed top plate 10 creates a relatively enclosed space inside the collection housing 5, which facilitates guiding the collection path of debris, allowing debris to enter the collection box 1 more smoothly through the conveyor 6, preventing debris from escaping during collection, and improving collection efficiency and integrity.

[0078] This invention features several drainage holes 11 on the fixed base plate 9 of the collection housing 5, enabling preliminary filtration. During the movement of the collection device, water and floating debris simultaneously enter the collection housing 5. The debris is hooked by the hook 7 and fed into the conveyor 6, while the water carried onto the conveyor belt 15 by the debris flows out through the drainage holes 11. This design effectively prevents a large amount of water from entering the collection box 1 along with the debris, reducing the workload of subsequent processing. Without the drainage holes 11, a large amount of water would accumulate in the collection box 1, increasing its weight and affecting the stability and operating efficiency of the collection device, putting greater pressure on subsequent processing equipment and reducing processing efficiency.

[0079] exist Figure 2 and Figure 3 In the embodiment shown, a propeller 12 is fixed to the outer side of the bottom surface of the fixed base plate 9 of each collection housing 5. The propeller 12 is used to propel the water surface suspended solids collection device to move on the water surface.

[0080] In this invention, the propeller 12 enables the collection device to move autonomously, overcoming the limitations of traditional fixed collection devices. Common fixed grilles or filters can only intercept floating debris in a fixed location, covering a limited area. However, the collection device provided by this invention, thanks to the propeller 12, can actively move towards areas where debris accumulates. When an increase in floating debris is detected in a specific area of ​​the water surface, the position of the collection device can be quickly adjusted for collection, greatly expanding the cleaning range. Taking a park's landscape lake as an example, the location of fallen leaves varies with the season; the collection device provided by this invention can flexibly move and collect accordingly, avoiding the hassle of manually moving equipment and significantly improving cleaning efficiency.

[0081] This invention, by incorporating multiple propellers 12, allows the collection device to better adapt to complex environments. Since the distribution of floating debris on the water surface is complex and varied, when the debris is distributed in a regular and concentrated manner, activating only one or some propellers 12 allows the collection device to move in a straight line or curve in a specific direction, accurately collecting the floating debris in that area, reducing energy waste, and improving collection targeting. If the debris is distributed irregularly and scattered, activating all propellers 12 simultaneously and controlling the propulsion direction allows the collection device to rotate in place, forming a vortex in the water. Under the influence of the vortex, the originally scattered floating debris will move closer to the collection device, indirectly expanding the collection area and achieving efficient cleaning of scattered floating debris, fully demonstrating the adaptability of the collection device to different debris floating distribution states.

[0082] In this invention, adjacent collecting components 2 are connected by flexible connectors 3 to form a limiting area. As the propeller 12 moves the collecting device, floating debris on the water surface is intercepted by the flexible connectors 3 and collected around the collecting device. At this time, the propeller 12 continuously provides power to keep the collecting device moving, ensuring that floating debris is continuously intercepted and collected. The hook 7 can more efficiently hook the debris into the conveyor 6, achieving rapid cleaning, further improving collection efficiency and reducing manual labor intensity.

[0083] In this invention, the propeller 12 works in conjunction with other components of the collection device to ensure stable overall operation. The conveyor 6 is responsible for transporting the hooked debris to the collection tank 1. During the movement of the propeller 12, it continuously provides the conveyor 6 with a new source of floating debris, maintaining the continuity of the conveying operation. The liquid level detector 26 monitors the water level. When the amount of debris collected in the collection tank 1 increases, causing the collection device to sink, it controls the airbag 4 to inflate and adjust the buoyancy. The movement of the propeller 12 also helps the liquid level detector 26 to detect changes in the liquid level in a timely manner. The three components work together to ensure stable operation of the collection device under different working conditions, continuously and efficiently collecting floating debris on the water surface.

[0084] exist Figure 2 In the embodiment shown, the conveyor 6 is inclinedly disposed inside the collection housing 5. The conveyor 6 has a feeding end and a discharging end. The feeding end is close to the hook 7, and the discharging end extends into the collection box 1. The feeding end is lower than the discharging end. Debris floating on the water surface is conveyed from the feeding end to the discharging end and falls into the collection box 1 from the discharging end.

[0085] In separating water and debris, the inclined conveyor 6 is highly effective. During the collection of suspended debris from the water surface, a large amount of water inevitably mixes into the collection housing 5. If the conveyor 6 were horizontal, this water carried by the debris into the conveyor belt 15 would likely be sent to the collection box 1 along with the debris. If a large amount of water is mixed into the collection box 1, over time, the collected debris will ferment, deteriorate, and breed bacteria, causing secondary pollution to the surrounding environment. In this invention, the inclined conveyor 6 allows the water remaining on the conveyor belt 15 to flow naturally down the inclined conveyor belt 15 under gravity, achieving effective separation of water and debris. Thus, only the debris to be processed enters the collection box 1, reducing the water content in the collection box 1 and lowering the difficulty and cost of subsequent processing. Simultaneously, the friction between the debris and the conveyor belt 15 ensures that the debris is stably conveyed to the collection box 1 without slipping down the conveyor belt 15, guaranteeing the normal operation of the collection process.

[0086] exist Figure 1 and Figure 4 In the embodiment shown, the conveyor 6 includes an active roller 13, a driven roller 14, a conveyor belt 15, and a drive member 16. The conveyor belt 15 is wound around the outer periphery of the active roller 13 and the driven roller 14. The active roller 13 is externally connected to the drive member 16, which is used to drive the active roller 13 to rotate. The active roller 13 is close to the hook member 7.

[0087] The structural design of the conveyor 6 provided by this utility model offers a stable and efficient power source for conveying debris. The drive component 16 drives the active roller 13 to rotate, thereby causing the conveyor belt 15, which is arranged around the active roller 13 and the driven roller 14, to rotate, thus conveying the debris. The drive component 16 can be precisely adjusted according to actual needs. For example, in areas with a large amount of floating debris and greater collection difficulty, the output power of the drive component 16 can be increased to increase the rotational speed of the active roller 13, thereby accelerating the running speed of the conveyor belt 15 and improving collection efficiency. In areas with relatively little floating debris, the output power of the drive component 16 can be appropriately reduced to save energy. This flexible power control method allows the collection device to adapt to different working scenarios, effectively improving the practicality and economy of the collection device.

[0088] This invention positions the active roller 13 close to the hook 7. After the hook 7 hooks floating debris into the collection housing 5, the debris quickly comes into contact with the high-speed conveyor belt 15. Because the active roller 13 is close to the hook 7, the conveyor belt 15 has a higher linear velocity at the feeding end, enabling it to quickly grab the debris and stably transport it to the collection box 1. This design effectively reduces the residence time of debris in the collection housing 5, preventing it from slipping or accumulating due to water flow fluctuations or its own weight, thus improving the success rate and continuity of collection.

[0089] exist Figure 2 , Figure 3 and Figure 4 In the illustrated embodiment, the hook component 7 includes a rotating shaft 17 and several collecting hooks 18. The axis of the rotating shaft 17 is perpendicular to the direction of water flow. Both ends of the rotating shaft 17 are movably fixed to two fixed side plates 8. Bearings 19 are provided at the connection points between the two ends of the rotating shaft 17 and the fixed side plates 8, and the two ends of the rotating shaft 17 rotate within the bearings 19 (e.g., ...). Figure 3 and Figure 4 (As shown).

[0090] exist Figure 1 and Figure 2 In the embodiment shown, the collecting hook 18 has an L-shaped structure (e.g., Figure 2 As shown), one end of the collection hook 18 is fixed to the outer wall of the rotating shaft 17, and several collection hooks 18 are staggered along the circumference of the outer wall of the rotating shaft 17 (as shown). Figure 1 (As shown).

[0091] In this invention, the collecting hooks 18 are L-shaped and staggered along the outer wall of the rotating shaft 17, greatly increasing the contact area with floating debris and the probability of hooking it up. When the collecting device is in operation, the rotating shaft 17 drives the collecting hooks 18 to rotate. The staggered L-shaped collecting hooks 18 can effectively hook up different types of floating debris using their unique shape and distribution, significantly improving collection efficiency compared to ordinary flat or single-structure collecting tools.

[0092] exist Figure 2 , Figure 3 and Figure 4 In the illustrated embodiment, a transmission wheel 20 is respectively provided at both ends of the rotating shaft 17. The transmission wheels 20 at both ends of the rotating shaft 17 are connected to both ends of the drive roller 13 via belts 21. The drive roller 13 drives the conveyor belt 15 to rotate while simultaneously driving the rotating shaft 17 to rotate via belts 21 and transmission wheels 20 (e.g., Figure 2 and Figure 4 (As shown).

[0093] This invention connects the transmission wheels 20 at both ends of the rotating shaft 17 to the two ends of the active roller 13 via belts 21. This ingenious transmission connection transmits the power of the active roller 13 to the rotating shaft 17, allowing the hook 7 and the conveyor 6 to work together, playing a key role in improving the performance of the entire collection device. This design ensures the stable and synchronous operation of the hook 7 and the conveyor 6. The active roller 13 and the rotating shaft 17 are connected by belts 21. When the active roller 13 rotates stably under the drive of the drive member 16, the rotating shaft 17 can rotate synchronously and stably with the help of the belt 21. Because the rotating shaft 17 and the active roller 13 rotate synchronously, the rotation speed of the hook 18 of the hook 7 and the conveying speed of the conveyor belt 15 can be precisely matched. After the hook 18 quickly hooks up the debris floating on the water surface, the conveyor belt 15, which runs synchronously with it, can quickly convey the debris to the collection box 1. This efficient cooperation greatly increases the amount of debris that the collection device can process per unit time. If the hooking component 7 and the conveying component 6 are not synchronized, it will lead to low collection efficiency, or even the accumulation of debris and blockage of the collection device.

[0094] Furthermore, this design effectively reduces the energy consumption and maintenance costs of the equipment. By simultaneously transmitting the power of the drive roller 13 to the conveyor belt 15 and the rotating shaft 17, it avoids the need for a separate drive unit for the rotating shaft 17, thus reducing the number of components and energy consumption. Fewer components mean a lower probability of failure and lower maintenance costs. During equipment operation, there is no need to invest a large amount of energy and manpower to maintain multiple drive units, improving the overall economic efficiency of the equipment.

[0095] exist Figure 1 and Figure 2 In the illustrated embodiment, the collection box 1 is a box body composed of a collection top plate 22, four collection side plates 23, and a collection bottom plate 24. The edge of the collection top plate 22 is hinged to the edge of any of the collection side plates 23 to enable the collection top plate 22 to be flipped open. A transparent observation window 29 is embedded in the collection top plate 22 (e.g., a transparent observation window 29). Figure 2 (As shown).

[0096] In this utility model, the collecting top plate 22 and the collecting side plate 23 are hinged (e.g. Figure 2As shown, the top plate 22 can be flipped open, greatly facilitating the cleaning and maintenance of the collection tank 1. In actual wastewater treatment processes, a large amount of debris accumulates inside the collection tank 1. Prolonged accumulation can lead to odors, bacterial growth, and even affect the normal operation of the equipment. By flipping open the top plate 22, staff can easily access the interior of the collection tank 1 to thoroughly clean every corner, ensuring the collection tank 1 remains in good working condition. Furthermore, this design facilitates the inspection, repair, or replacement of components inside the collection tank 1, such as cleaning potentially clogged discharge ends of the conveyor 6 and checking for damage to the bottom of the collection tank 1, effectively extending the equipment's lifespan and reducing maintenance costs.

[0097] The design of the top collection plate 22 helps improve the safety and sealing of the entire collection device. During equipment operation, the closed top collection plate 22 prevents collected debris from splashing out, avoiding pollution and harm to the surrounding environment and personnel. At the same time, good sealing also reduces odor emission, minimizes the impact on the surrounding air environment, and creates a more comfortable working environment for operators.

[0098] A transparent observation window 29 is embedded in the top plate 22, allowing operators to observe the debris collection in the collection tank 1 in real time without frequently opening the top plate 22. On one hand, this helps operators monitor the collection progress and determine if the collection tank 1 is about to fill. When the collection tank 1 is nearing its capacity limit, timely cleaning can be arranged to prevent debris overflow due to overfilling, which could affect collection efficiency and the aquatic environment. On the other hand, the observation window 29 allows observation of the type and condition of the collected debris. If abnormal substances are found, such as large amounts of chemical waste or unknown pollutants, appropriate measures can be taken promptly to adjust subsequent treatment processes, ensuring the quality and safety of wastewater treatment.

[0099] exist Figure 2 In the embodiment shown, each collecting side plate 23 is provided with a collecting port 25 that communicates with the collecting shell 5, and the unloading end of the conveying component 6 extends into the interior of the collecting box 1 through the collecting port 25.

[0100] In this invention, the collection port 25 enables seamless connection between the collection component 2 and the collection box 1. The conveyor 6 in the collection housing 5 is responsible for conveying the floating debris collected by the hook 7, while the collection port 25 is the key channel for the debris to enter the collection box 1. The discharge end of the conveyor 6 extends into the collection box 1 through the collection port 25, allowing the debris to fall directly and smoothly from the conveyor 6 into the collection box 1, avoiding possible drops or spills during the transfer process, and ensuring the continuity and efficiency of the collection process.

[0101] Secondly, the reasonable design of the collection port 25 effectively avoids the risk of secondary pollution during the collection process. Without the collection port 25, or if the collection port 25 is not designed properly, debris may come into contact with the external environment of the collection box 1 when entering the collection box 1, causing the pollutants carried on the debris to leak into the surrounding water. However, the collection port 25 of this utility model is closely matched with the unloading end of the conveyor 6, so that the debris enters the collection box 1 from the collection shell 5 in a relatively closed environment, which greatly reduces the possibility of pollutant leakage.

[0102] Furthermore, the presence of the collection port 25 facilitates the maintenance and cleaning of the collection device. When it is necessary to clean the collection box 1 or the collection component 2, the collection port 25 provides an easy-to-operate channel. Workers can more easily inspect, clean and maintain the unloading end of the conveyor 6 through the collection port 25, and it is also convenient to clean the area inside the collection box 1 near the collection port 25.

[0103] exist Figure 1 and Figure 2 In the embodiment shown, a liquid level detector 26 is provided on the outer wall of the collection tank 1, an air pump 28 is connected to the air bag 4, and the liquid level detector 26 is electrically connected to the controller 27. The controller 27 provides feedback control to the air pump 28. When the water level exceeds the liquid level detector 26, the liquid level detector 26 sends a sensing signal to the controller 27. When the controller 27 receives the sensing signal, it sends a control command to the air pump 28 to inflate the air bag 4.

[0104] During the collection of suspended debris on the water surface, as the amount of debris collected in the collection tank 1 increases, the overall weight of the collection device gradually increases. Once the weight exceeds the buoyancy provided by the airbag 4, the collection device will sink, affecting the collection effect and even causing the collection operation to fail. This invention, through the coordinated operation of the level detector 26, controller 27, and air pump 28, can monitor the water level and the floating status of the collection device in real time. When the water level exceeds the level detector 26, it indicates that the collection device may sink due to excessive debris. The level detector 26 sends a sensing signal to the controller 27, which then controls the air pump 28 to inflate the airbag 4, increasing the buoyancy of the airbag 4 and causing the collection device to float back to a suitable position, always remaining on the water surface for efficient collection operations, ensuring the continuity and stability of the collection work.

[0105] Furthermore, this design enables automated adjustment of the collection device, significantly improving its intelligence. It eliminates the need for constant manual monitoring of the device's buoyancy, reducing manual operation costs and human error. Operators only need to make simple settings before operation, and the device automatically adjusts the buoyancy of the air bladder 4 according to changes in water level, greatly improving its environmental adaptability.

[0106] It should be noted that the unloading end of the conveyor 6 provided by this utility model should be located above the water level to ensure that the debris conveyed to the unloading end does not contain a large amount of water, which would cause a large amount of water to enter the collection box 1 and affect the overall weight of the collection device. More ideally, the hook 7 should be partially immersed in the water, while the entire conveyor 6 should be located above the water surface.

[0107] The operation process of the water surface suspended solids collection device provided by this utility model is as follows:

[0108] (1) Preparation: Before use, the operator should start the air pump 28 connected to the air bag 4 to fill the air bag 4 with enough gas; at the same time, check whether the components of the collection device are connected firmly, such as the connection between the collection shell 5 and the collection box 1, the installation of the conveyor 6 and the hook 7, etc., to ensure that the equipment is free from faults and that all components can operate normally; after confirming that everything is correct, place the collection device on the surface of the water body to be treated. At this time, the air bag 4 provides buoyancy for the collection device, so that the entire collection device floats stably on the water surface, preparing for the subsequent collection of floating debris on the water surface.

[0109] (2) Device movement and debris collection: Start the thruster 12 to provide power to the collection device and make it move on the water surface. If the debris floating on the water surface is distributed in a regular and concentrated manner, only some of the thrusters 12 need to be turned on, and the collection device can move in a straight line or curve in the set direction and accurately drive to the debris collection area. If the floating debris is distributed irregularly and scattered, all the thrusters 12 need to be turned on, and the collection device can be rotated in place by controlling the direction of propulsion. During the movement of the collection device, the limiting area formed by the flexible connector 3 between adjacent collection components 2 plays a role. The flexible connector 3 will intercept the debris floating on the water surface and make it gather around the collection device, which is convenient for subsequent collection operations.

[0110] (3) Debris hooking and conveying: When the collection device approaches the floating debris, the hooking part 7 and the conveying part 6 start to work, the driving part 16 starts, and drives the active roller 13 to rotate. The active roller 13 drives the conveyor belt 15 to rotate, and at the same time, it drives the rotating shaft 17 and the collection hook 18 on it to rotate through the belt 21 and the transmission wheel 20. During the rotation, the collection hook 18 hooks the floating debris on the water surface from various angles. The hooked debris is transferred to the conveyor belt 15, and the debris moves from the loading end to the unloading end along the conveyor belt 15.

[0111] (4) Debris collection and box cleaning: After the debris moves to the unloading end with the conveyor belt 15, it falls into the collection box 1 to complete the collection. The edge of the collection top plate 22 is hinged to the collection side plate 23, which can be flipped open to facilitate the cleaning of the debris accumulated in the collection box 1. The transparent observation window 29 embedded in the top plate allows the operator to observe the collection situation in the collection box 1 in real time, such as the collection progress, the type and status of debris, so as to arrange the cleaning work in time and avoid the collection box 1 from being too full and causing the debris to overflow.

[0112] (5) Device status monitoring and adjustment: The liquid level detector 26 installed on the outer wall of the collection tank 1 monitors the water level and the floating status of the device in real time. As the amount of debris collected in the collection tank 1 increases, the overall weight of the collection device increases. When the water level exceeds the liquid level detector 26, the liquid level detector 26 sends a sensing signal to the controller 27. After receiving the signal, the controller 27 sends a control command to the air pump 28 to inflate the air bag 4, increase the buoyancy of the air bag 4, prevent the collection device from sinking, and ensure that the feed end of the collection component 2 is above the water surface, maintaining the normal working status of the collection device.

[0113] The applicant declares that the above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art should understand that any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model fall within the protection and disclosure scope of the present utility model.
