Description

Technical Field

[0001] This utility model relates to the field of water body cleaning technology, specifically to a floating debris interception, discharge, and cleaning device based on cable transmission. Background Technology

[0002] Floating debris barriers at hydropower stations are crucial facilities for intercepting floating debris such as tree branches, household waste, and aquatic plants in waterways. Their core function is to prevent blockages at the intake, ensure the safe and stable operation of the hydropower station, and improve power generation efficiency. However, debris barriers are typically located in the waterway at the power station's intake, presenting significant challenges for debris removal operations.

[0003] Current mainstream cleaning methods have the following drawbacks:

[0004] 1) Limitations of cleaning vessel operation: It relies on manual operation, cannot achieve continuous operation, has poor stability in waters with high flow rates when the power plant is generating electricity, and has high operation and maintenance costs.

[0005] 2) Fixed grab buckets have insufficient adaptability: the cleaning range is limited, making it difficult to cover large areas of debris discharge. When faced with water level fluctuations, the installation height needs to be frequently adjusted, resulting in low efficiency under complex working conditions with drastic water level changes.

[0006] 3) Existing equipment is inefficient: Traditional cleaning methods cannot meet the needs of continuous, efficient and low-consumption operations, especially when the water level fluctuates greatly, the cleaning effect will be significantly reduced.

[0007] While various cleaning devices exist in the current technology, they generally suffer from drawbacks such as complex structure, poor adaptability, or high cost. For example, some devices use rigid connection structures, which cannot float synchronously with the debris barrier, causing the cleaning position to deviate; others rely on hydraulic drive or complex transmission systems, increasing equipment failure rate and maintenance costs. Utility Model Content

[0008] The purpose of this invention is to provide a floating debris interception and cleaning device based on cable transmission. By drawing on the operating principle of cable cars, a steel wire rope circulating transmission system is constructed, and synchronous floating with the debris interception is achieved through flexible connection. This breaks through the limitations of traditional cleaning methods and provides a high-efficiency, adaptive, and low-cost cleaning solution.

[0009] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a floating debris barrier and debris removal device based on cable transmission, including a debris removal rake, a debris removal drive steel wire rope, a debris removal drive wheel, a debris removal driven wheel, a transfer component, a debris barrier, a debris barrier support component, and a debris barrier guide rail.

[0010] The cleaning rake is fixed on the cleaning drive wire rope, and the cleaning drive wire rope is connected in a loop between the cleaning drive wheel and the cleaning driven wheel;

[0011] The debris barrier is connected to a fixed steel wire rope on the side near the cleaning rake, and the top of the debris barrier is connected to the cleaning drive steel wire rope through the adapter.

[0012] The cleaning drive wheel and the cleaning driven wheel are respectively installed on the guide rails of the intercepting bar on both sides of the river through the bar support. The bar support and the bar guide rails make the cleaning drive wire rope float synchronously with the bar as the water level changes.

[0013] As a preferred embodiment of the floating debris interception, discharge, and cleaning device based on cable transmission, the cleaning drive wheel is driven by a geared motor. The geared motor and the cleaning drive wheel are meshed through gears, and the power of the geared motor is transmitted to the cleaning drive wheel to drive the cleaning drive wire rope.

[0014] As a preferred embodiment of a floating debris interception, discharge, and cleaning device based on cable transmission, the cleaning driven wheel is installed on the opposite side of the cleaning drive wheel. The cleaning driven wheel supports the cleaning drive wire rope and guides the cleaning drive wire rope to form a closed-loop transmission circuit.

[0015] As a preferred embodiment of a floating debris interception and removal device based on cable drive, the debris removal rake is made of metal and is fixed to the debris removal drive wire rope by a clamp and moves with the debris removal drive wire rope to drive away floating objects on the water surface.

[0016] As a preferred embodiment of a floating debris interception, discharge, and cleaning device based on cable transmission, the cleaning rake is provided with a buoy to balance the weight of the cleaning rake.

[0017] As a preferred embodiment of the floating debris barrier and debris removal device based on cable transmission, the device is provided with two fixed steel wire ropes, which are respectively connected to the upper and lower parts of the debris barrier.

[0018] Both ends of the fixed steel wire rope are connected to the sides of the sewage interception support through steel wire rope mounting seats.

[0019] As a preferred embodiment of a floating debris interception and cleaning device based on cable transmission, several guide wheels are distributed at the contact positions of the debris interception support and the debris interception guide rail.

[0020] The beneficial effects of this utility model are as follows:

[0021] First, through the cooperation between the support components of the debris barrier and the guide rail of the debris barrier, the cleaning drive wire rope can rise and fall synchronously with the debris barrier, without the need for manual adjustment of the installation height. This significantly improves the adaptability to water level fluctuations (such as water level changes caused by flood season or power station operation), ensuring that the cleaning rake is always in the best working position, and solving the problem of low efficiency of traditional fixed equipment under complex water level conditions.

[0022] Secondly, the cleaning drive wire rope is looped, connecting the cleaning drive wheel and the cleaning driven wheel to form a circulating transmission structure. The motor drives the cleaning drive wheel, which in turn drives the wire rope to rotate continuously, causing the cleaning rake to move back and forth along the water surface continuously. This can continuously drive the debris to the shore, breaking through the limitations of traditional cleaning boats that rely on manual labor and cannot operate continuously, greatly improving cleaning efficiency, and is especially suitable for the rapid cleaning of large areas of floating debris.

[0023] Third, the debris barrier is flexibly connected to the cleaning drive wire rope via a transfer component. Combined with the tension of the fixed wire rope, the entire device and the debris barrier form a linked whole. Under the impact of water flow, the flexible structure can buffer the force, avoiding the risk of equipment damage caused by rigid connections, while ensuring the stability of the cleaning path. This makes it suitable for high-velocity water areas such as power plant inlets.

[0024] Fourth, two sets of cleaning drive wheels and cleaning driven wheels are installed on both banks of the river. Through a steel wire rope transmission system spanning the water surface, the cleaning rake can cover a large area of ​​water in front of the debris discharge, solving the problem of limited cleaning range of traditional grab bucket machines. At the same time, the modular structure design facilitates installation and maintenance, reducing the complexity of equipment layout.

[0025] Fifth, it eliminates the need for large cleaning vessels or complex hydraulic systems. The sliding guidance of the guide wheels on the support components reduces mechanical wear and the probability of failure. Furthermore, automated transmission reduces manual intervention, significantly lowering labor costs and maintenance intensity, making it more economical than traditional cleaning methods.

[0033] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0035] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model embodiment provides a floating debris barrier 6 debris removal and cleaning device based on cable transmission, including a debris removal rake 1, a debris removal drive steel wire rope 2, a debris removal drive wheel 3, a debris removal driven wheel 4, a transfer component 5, a debris barrier 6, a debris barrier support component 7, and a debris barrier guide rail 8.

[0036] The cleaning rake 1 is fixed to the cleaning drive wire rope 2, which is looped between the cleaning drive wheel 3 and the cleaning driven wheel 4. The looped wire rope 2 connects the drive wheel and driven wheel, forming a closed transmission circuit. The cleaning rake 1, as the actuating component, is fixed to the cleaning drive wire rope 2. The movement of the cleaning drive wire rope 2 drives the cleaning rake 1 to move reciprocally along the water surface, continuously driving away floating debris. This design uses a flexible cable to transmit power, adapting to water surface fluctuations while providing stable traction.

[0037] The debris barrier 6 is connected to a fixed steel wire rope 12 on the side near the cleaning rake 1. The top of the debris barrier 6 is connected to the cleaning drive steel wire rope 2 via the adapter 5. The fixed steel wire rope 12 connects the debris barrier 6 to the supporting structures on both sides of the river, forming a stable interception boundary. The adapter 5 enables flexible linkage between the debris barrier 6 and the cleaning drive steel wire rope 2. When the water level rises or falls, the debris barrier 6 floats with the water level via the fixed steel wire rope 12, while the cleaning drive steel wire rope 2 rises and falls synchronously via the adapter 5, ensuring that the relative position of the cleaning rake 1 and the debris barrier 6 remains unchanged, thus maintaining the effectiveness of the cleaning operation.

[0038] The cleaning drive wheel 3 and the cleaning driven wheel 4 are respectively mounted on the debris barrier guide rails 8 on both banks of the river via the debris barrier support 7. The debris barrier support 7 and the debris barrier guide rails 8 enable the cleaning drive wire rope 2 to float synchronously with the debris barrier 6 as the water level changes. The debris barrier support 7 serves as the mounting carrier for the cleaning drive wheel 3 and the cleaning driven wheel 4, and slides up and down in cooperation with the debris barrier guide rails 8. When the water level fluctuates, the debris barrier support 7 rises and falls along the debris barrier guide rails 8, driving the cleaning drive wheel 3 and the cleaning driven wheel 4 to rise and fall synchronously, thereby adjusting the height of the cleaning drive wire rope 2. This design ensures that the cleaning drive wire rope 2 always remains synchronized with the debris barrier 6 through mechanical linkage, preventing the cleaning rake 1 from leaving the effective working area due to water level changes.

[0039] In this embodiment, the cleaning drive wheel 3 is driven by a reduction motor 9. The reduction motor 9 and the cleaning drive wheel 3 are meshed through gears, and the power of the reduction motor 9 is transmitted to the cleaning drive wheel 3 to drive the cleaning drive wire rope 2 to move.

[0040] Specifically, the geared motor 9 provides the power source, reduces the speed and increases the torque through a reducer, and then transmits the power to the cleaning drive wheel 3 through gear meshing. Gear transmission features high transmission efficiency and a stable transmission ratio, allowing precise control of the running speed of the cleaning drive wire rope 2 to meet the operational needs of different cleaning scenarios (such as high-velocity or low-velocity water areas). By adjusting the speed of the geared motor 9, the moving speed of the cleaning rake 1 can be flexibly adjusted, optimizing cleaning efficiency.

[0041] In this embodiment, the cleaning driven wheel 4 is installed on the opposite side of the cleaning drive wheel 3. The cleaning driven wheel 4 supports the cleaning drive wire rope 2 and guides the cleaning drive wire rope 2 to form a closed-loop transmission circuit.

[0042] Specifically, the driven pulley 4, as the driven end of the cleaning drive wire rope 2 circuit, primarily supports the cleaning drive wire rope 2 and guides it to complete its cyclic motion. The driven pulley 4 can rotate freely around its own axis, reducing the running resistance of the wire rope through rolling friction. Simultaneously, it ensures that the cleaning drive wire rope 2 remains taut between the cleaning drive pulley 3 and the driven pulley 4, preventing transmission failure due to slack. The closed-loop circuit design allows the cleaning drive wire rope 2 to continuously circulate, providing continuous driving force to the cleaning rake 1.

[0043] In this embodiment, the cleaning rake 1 is made of metal. The cleaning rake 1 is fixed to the cleaning drive wire rope 2 by the clamp 10 and moves with the cleaning drive wire rope 2 to drive away floating objects on the water surface.

[0044] Specifically, the metal-made cleaning rake 1 is characterized by high strength and corrosion resistance, making it suitable for long-term underwater operation and operation in complex water environments. The clamp 10 features a detachable design, facilitating the installation, maintenance, and replacement of the rake. When the wire rope moves, the rake moves synchronously, using its toothed structure to generate thrust on floating debris (such as branches, aquatic plants, and household waste), gradually driving the debris to the shore or designated collection area, thus achieving mechanized cleaning.

[0045] In this embodiment, a float box 11 is provided on the upper part of the cleaning rake 1 to balance the weight of the cleaning rake 1.

[0046] Specifically, the float 11 generates buoyancy through built-in air or lightweight materials, offsetting the weight of the metal cleaning rake 1 and keeping it suspended on the water surface. This prevents the cleaning rake 1 from sinking due to its own weight, which would reduce cleaning efficiency. The balanced design of buoyancy and weight ensures that the cleaning rake 1 can always operate close to the water surface, effectively contacting floating objects and applying driving force, while reducing the vertical load on the cleaning drive wire rope 2 and extending the service life of the transmission components.

[0047] In this embodiment, there are two fixed steel wire ropes 12, which are respectively connected to the upper and lower parts of the debris barrier 6; the two ends of the fixed steel wire ropes 12 are respectively connected to the side of the debris barrier support 7 through steel wire rope mounting seats 13.

[0048] Specifically, two fixed steel wire ropes 12 act on the upper and lower parts of the debris barrier 6 respectively, forming a stable two-point connection, which can effectively resist the impact of water flow and wind and wave loads, preventing the debris barrier 6 from tilting or shifting. The steel wire rope mounting base 13, as the connecting hub, adopts a high-strength structural design to ensure a reliable connection between the fixed steel wire ropes 12 and the debris barrier support 7. Through the distributed connection at the upper and lower parts, the debris barrier 6 can be evenly stressed, improving the stability of the overall structure, and maintaining its interception function, especially in high-velocity waters.

[0049] In this embodiment, a plurality of guide wheels 14 are distributed at the contact positions of the sewage discharge support 7 and the sewage discharge guide rail 8.

[0050] Specifically, guide wheels 14 are installed between the contact surfaces of the debris barrier support 7 and the debris barrier guide rail 8, converting sliding friction into rolling friction and significantly reducing the resistance of the debris barrier support 7 when it moves up and down along the debris barrier guide rail 8. The distribution design of the guide wheels 14 ensures that the debris barrier support 7 moves smoothly in the vertical direction, avoiding jamming caused by excessive frictional resistance, while also reducing mechanical wear and extending the service life of the debris barrier guide rail 8 and the debris barrier support 7. In addition, the guide wheels 14 can also limit the movement trajectory of the debris barrier support 7, ensuring that the cleaning drive wire rope 2 always remains parallel to the debris barrier 6, maintaining the stability of the transmission system.

[0051] The installation process of this utility model is as follows:

[0052] Fixed guide rails 8 for the debris barrier are installed on both banks of the river. The debris barrier support 7 is mounted on the guide rails 8 via guide wheels 14, ensuring that the debris barrier support 7 can rise and fall freely along the guide rails 8. Cleaning drive wheels 3 and cleaning driven wheels 4 are installed on the debris barrier support 7 on both sides, and connected to form a ring-shaped transmission structure via a cleaning drive wire rope 2. The cleaning rake 1 is fixed to the cleaning drive wire rope 2 via a clamp 10, and its position is adjusted to be in the water in front of the floating debris barrier 6. The top of the debris barrier 6 is connected to the cleaning drive wire rope 2 via an adapter 5, and the upper and lower parts of the debris barrier 6 are fixed to the wire rope mounting seats 13 on the side of the support using two fixing wire ropes 12, forming an integrated linkage structure.

[0053] Install the geared motor 9, which is connected to the cleaning drive wheel 3 via gear meshing. Test the rotation and speed adjustment functions of the geared motor 9 by powering it on, ensuring that the cleaning drive wire rope 2 runs smoothly without jamming or loosening. Check the buoyancy balance effect of the float box 11 on the cleaning rake 1, ensuring that the rake stays close to the water surface without significant sinking.

[0054] During operation, when the river water level fluctuates (such as during high tide or power station operation), the debris barrier 6 rises and falls with the water level via the fixed steel wire rope 12, while the cleaning drive steel wire rope 2 moves synchronously via the adapter 5. The debris barrier support 7 rises and falls along the debris barrier guide rail 8, and the guide wheel 14 reduces resistance through rolling friction, ensuring that the cleaning drive wheel 3 and the cleaning driven wheel 4 move smoothly with the debris barrier support 7, maintaining the relative height of the cleaning drive steel wire rope 2 and the debris barrier 6.

[0055] The electric motor is started, and the power is transmitted to the cleaning drive wheel 3 after being reduced in speed and torque by the reducer. The cleaning drive wheel 3 rotates, pulling the cleaning drive wire rope 2. The cleaning rake 1 moves with the cleaning drive wire rope 2, using its toothed structure to generate thrust on floating objects (such as branches, aquatic plants, and household waste) on the water surface, gradually driving the debris towards the shore or the designated cleaning area. The cleaning driven wheel 4 supports the cleaning drive wire rope 2 and guides it back, forming a continuous transmission loop to ensure that the cleaning rake 1 can operate continuously without manual intervention.

[0056] The motor control system adjusts the rotation speed based on the density of the pollutants and the flow rate: In high-load scenarios (such as during the flood season when there are large amounts of pollutants), the rotation speed is increased to accelerate the movement of the rake teeth and enhance the efficiency of removing pollutants; in low-load scenarios, the rotation speed is reduced to decrease energy consumption and prevent water flow disturbance from causing the pollutants to spread.

[0057] When the cleaning rake 1 encounters a large obstacle (such as a tree trunk), causing a sudden increase in the load on the cleaning drive wire rope 2, the overload protection device built into the reducer (such as a shear pin or torque limiter) is automatically triggered, cutting off power transmission to prevent damage to the geared motor 9 or transmission components. Operators must promptly clear the obstacle, relieve the overload, and restart the device. When the water level fluctuates drastically beyond the guide rail's travel limit, the device uses the flexible connection of the fixed wire rope 12 and the adapter 5 to buffer the force, preventing structural damage caused by rigid connections. The system can be equipped with a water level monitoring sensor; when the water level exceeds the safe range, it automatically stops and restarts after the water level returns to the normal range. Through this process, the device can achieve automated and continuous cleaning and removal of debris in the water area in front of the floating debris barrier 6, effectively addressing different hydrological conditions and debris types, and improving the efficiency and safety of cleaning operations at hydropower stations.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
