Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a cable-driven salvage system. Background Technology

[0002] Currently, the interception and removal of floating debris remains a pressing technical challenge in the operation and management of water conservancy facilities such as hydropower stations and reservoirs. Especially when faced with the large amounts of floating debris brought by surging river water during the flood season, traditional debris-blocking rafts, while capable of intercepting some, can easily allow a large amount of debris to escape from beneath the rafts if not removed promptly.

[0003] Current methods of debris removal rely on manual operation of debris removal vessels to approach and retrieve objects. For example, Chinese patent CN217998014U discloses a multifunctional debris removal device. Its debris-catching device can move back and forth under the action of a telescopic mechanism. After maintaining a safe distance between the front end of the float and the area to be retrieved, the telescopic mechanism pushes the debris-catching device to the area, ensuring it can grab the floating debris at the debris screen and on the screen. This makes the debris removal device suitable for retrieval operations in certain narrow spaces.

[0004] However, high current speeds increase the stress on the hull, making it prone to loss of control, collisions, or capsizing accidents, limiting the operational window and resulting in extremely low salvage efficiency. During the turbulent flood season, conventional debris removal vessels, due to their inherent stability and power limitations, find it difficult to safely approach and remain in areas where floating debris accumulates for salvage operations. Forcing operations carries significant safety risks of vessel loss of control and capsizing, making simply blocking debris the norm. The floating debris layer in front of the debris-blocking ditch continuously thickens and widens, which in turn further intensifies the impact of the current on the debris-blocking ditch and the structural load, creating a vicious cycle.

[0005] It is evident that existing debris removal equipment lacks precise attitude control methods, making it difficult to achieve flexible movement and accurate positioning of debris removal vessels under high current velocities. Whether performing salvage operations or during movement, debris removal vessels require a significant amount of power to resist the impact of high-speed water currents, which not only limits movement accuracy but also consumes excessive power resources.

[0006] In view of the above, this application is hereby submitted. Utility Model Content

[0007] This application provides a cable-driven salvage system, which solves the technical problem in the prior art that cleanup vessels are difficult to move flexibly in high-speed currents, and achieves the technical effect of making cleanup vessels difficult to move flexibly in high-speed currents.

[0008] In a first aspect, this application provides a cable-stayed salvage system, comprising: Flood barriers are installed across the working channel to intercept floating objects. The cleanup vessel is positioned upstream of the drift barrier, and the downstream end of the cleanup vessel is equipped with salvage equipment. The floating platform is located upstream of the cleanup vessel. The lateral traction winch includes at least two units, which are set opposite each other on both banks of the working channel. The two sides of the floating platform are connected to the lateral traction winch on the same side by lateral traction cables. The longitudinal traction winch is set on one bank of the working river channel. The longitudinal traction cable of the longitudinal traction winch is turned by the guide wheel on the floating platform and then connected to the fixing parts on the cleanup vessel. The fastener is located at the upstream end of the cleanup vessel, and the center of the fastener matches the axis of the cleanup vessel.

[0009] In some embodiments of this application, based on the aforementioned scheme, the floating platform includes a floating platform body and ears, with the ears symmetrically arranged at one end of the floating platform body near the downstream side along the water flow direction; The two sides of the floating platform are connected to the horizontal traction winches on the same side by horizontal traction cables, and the guide wheels are set on the upper surface of the floating platform.

[0010] In some embodiments of this application, based on the aforementioned scheme, one end of the floating platform body near the upstream side is configured as a curved surface facing away from the water flow, in order to reduce and evenly distribute the impact force of the water flow.

[0011] In some embodiments of this application, based on the aforementioned scheme, a stop wheel is also provided on the floating platform. The stop wheel and the guide wheel cooperate to form a clamping channel, and the longitudinal traction cable passes through the clamping channel and is connected to the fixing member. The gap between the cylindrical surface of the stop wheel and the cylindrical surface of the guide wheel is used to seal the rope groove of the guide wheel.

[0012] In some embodiments of this application, based on the foregoing scheme, it further includes: a tilt angle sensor for monitoring the tilt angle between the cleanup vessel and the water surface.

[0013] In some embodiments of this application, based on the foregoing scheme, it further includes: a deflection angle sensor for monitoring the deflection angle between the longitudinal traction cable and the axis of the cleanup vessel.

[0014] In some embodiments of this application, based on the foregoing scheme, the following further methods are also included: The slewing bearing mechanism, mounted on the floating platform, is used to make the guide wheel rotate with the longitudinal traction cable.

[0015] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: 1. The coordinated arrangement of the drift barrier, drift removal vessel, floating platform and traction winch, combined with the design of matching the center of the fixed component with the axis of the drift removal vessel, enables the drift removal vessel to move flexibly and be precisely positioned in the water, effectively covering the target salvage area, providing a structural foundation for efficient salvage of floating objects, while ensuring that each component is subjected to reasonable stress and operates stably.

[0016] 2. Through the structural design of the floating platform body and symmetrical ears, a reliable connection with the lateral traction cable is ensured, and the floating platform is subjected to balanced force during traction, avoiding skewing. This provides stable support for the guide wheel to perform its steering function, further ensuring the smooth operation of the entire traction system.

[0017] 3. The curved surface design on the upstream side of the floating platform can evenly distribute the impact force of the water flow, reduce the local impact damage of the water flow on the floating platform, and avoid the generation of eddy current interference. This helps the floating platform maintain a stable posture in complex water flow environments and improves the system's resistance to flow and operational durability.

[0018] 4. The stop wheel and guide wheel cooperate to form a clamping channel, and the gap between the cylindrical surface of the stop wheel and the cylindrical surface of the guide wheel is used to seal the rope groove of the guide wheel. This can accurately limit the movement trajectory of the longitudinal traction cable, prevent the cable from deviating or falling out of the wheel groove, and at the same time reduce the friction loss between the cable and the components through synchronous rotation, ensuring the accuracy and reliability of longitudinal traction.

[0019] 5. The tilt angle sensor can monitor the tilt angle of the cleanup vessel relative to the water surface in real time, promptly detect abnormal tilting of the vessel, provide safety warnings for the system, facilitate timely control measures, prevent safety accidents caused by excessive tilting of the cleanup vessel, and significantly improve operational safety.

[0020] 6. The deflection angle sensor can monitor the deflection angle between the longitudinal traction cable and the axis of the cleanup vessel in real time, helping the system to grasp the coordination status between the cable and the hull in a timely manner. By adjusting the traction parameters in a targeted manner, the system can correct the hull attitude and ensure that the cleanup vessel is always in the best working posture, thus ensuring the stable operation of the salvage operation.

[0021] 7. The slewing bearing mechanism can reduce wear on the longitudinal traction cable, optimize the cable stress environment, extend the cable service life, and at the same time ensure traction efficiency and system operation stability. Attached Figure Description

[0024] This application provides a cable-driven salvage system, which solves the technical problem in the prior art that cleanup vessels are difficult to move flexibly in high-speed currents.

[0025] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0026] Example 1 This application provides a cable-stayed vessel-moving salvage system. For example... Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 This is a top view schematic diagram of a cable-stayed salvage system provided in an embodiment of this application. Figure 2 This is a side view of a cable-stayed salvage system provided in an embodiment of this application. Figure 3 Provided for the embodiments of this application Figure 1 The structural schematic diagram shown in the dashed box A.

[0027] Figure 1 The direction of the middle arrow indicates the direction of water flow. Figure 1 The text shows the working channel and both banks. Figure 2 The image shows the shore and the water surface, with only one water surface located on pontoon 3 marked. It can be understood that there are two other identical water surfaces to the right of the marked location (located at both ends of the ship).

[0028] The cable-stayed salvage system includes: a drift barrier 1, a drift removal vessel 2, a floating platform 3, a transverse traction winch 4, and a longitudinal traction winch 5.

[0029] The drift barrier 1 is set across the working channel to intercept floating objects in the water flow, providing a target salvage area 11 for the cleanup vessel 2 to carry out centralized salvage operations.

[0030] The debris removal vessel 2 is positioned upstream of the debris blocking ditch 1 and typically employs a twin-engine, twin-propeller propulsion system, providing excellent power and stability. A salvage device 21, such as a hydraulically driven rotating arm and bucket, is installed at the downstream end of the vessel. This device allows for efficient salvage and unloading by controlling the pitch, rotation, and opening / closing of the bucket.

[0031] Floating platform 3 floats upstream of the cleanup vessel 2, serving as a floating support and for changing the direction of the longitudinal traction cable 51. The cleanup vessel 2 is moved through the coordination of the floating platform 3 and various traction winches. For details, refer to... Figure 3 The floating platform 3 includes a platform body 31 and lugs 32. The lugs 32 are symmetrically arranged at one end of the platform body 31 near the downstream side along the water flow direction. The lugs 32 ensure that the platform 3 is subjected to balanced force during traction and prevents tilting. The end of the platform body 31 near the upstream side is designed as a curved surface facing away from the water flow to reduce and evenly distribute the impact force of the water flow. Both sides of the platform body 31 are connected to the lateral traction winch 4 on the same side by lateral traction cables 41 to form a reference frame for the lateral movement of the cleaning vessel 2.

[0032] A guide wheel 61 and a stop wheel 62 are provided on the upper surface of the floating platform body 31. The stop wheel 62 and the guide wheel 61 cooperate to form a clamping channel. The longitudinal traction cable 51 passes through the clamping channel and is connected to the fixing component. The gap between the cylindrical surface of the stop wheel 62 and the cylindrical surface of the guide wheel 61 is used to seal the rope groove of the guide wheel 61 so as to rotate synchronously with the guide wheel 61. The longitudinal traction cable 51 is restricted to contraction or extension within the clamping channel. Even if the water level drops suddenly and causes a sudden change in the cable's elevation angle, it can prevent the cable from jumping off or slipping laterally, ensuring that the reversing angle is always accurate. It can precisely limit the movement trajectory of the longitudinal traction cable 51 and avoid cable deviation or detachment from the rope groove. At the same time, the synchronous rotation reduces frictional loss between the cable and the components, ensuring the accuracy and reliability of longitudinal traction.

[0033] Furthermore, a slewing bearing mechanism (not shown in the figure) is also installed on the floating platform 3 to make the guide wheel 61 rotate with the longitudinal traction cable 51. This can reduce the wear of the longitudinal traction cable 51, optimize the cable stress environment, extend the cable service life, and at the same time ensure traction efficiency and system operation stability.

[0034] The lateral traction winches 4 are used to control the movement of the cleanup vessel 2 along a direction perpendicular to the water flow. At least two lateral traction winches 4 are fixedly installed on both banks of the working channel. Each lateral traction winch 4 extends a lateral traction steel cable to the side of the floating platform 3. Through the coordinated control of the lateral traction winches 4 on both banks (one winding and the other releasing), the floating platform 3 is moved, thereby causing the cleanup vessel 2, which is associated with it via guide wheels 61, to move. This allows the cleanup vessel 2 to precisely cover the entire area of ​​floating debris accumulation within the working channel.

[0035] The longitudinal traction winch 5 is used to control the movement of the debris-clearing vessel 2 along a direction parallel to the water flow, and is usually located on one bank of the working channel. The longitudinal traction cable 51 extended from the longitudinal traction winch 5 first changes direction by passing around the guide wheel 61 on the floating platform 3, and then connects to the fixing component on the upstream side of the debris-clearing vessel 2. The center of the fixing component matches the axis of the debris-clearing vessel 2, that is, the installation center of the fixing component is located on the longitudinal axis of the debris-clearing vessel 2, to ensure that the traction force provided by the longitudinal traction cable 51 always acts on the centerline of the hull, avoiding the generation of torsional torque. Through the traction force provided by the longitudinal traction cable 51, the movement of the debris-clearing vessel 2 or its stopping on the water surface can be controlled, enabling it to accurately enter the target salvage area 11 with dense floating objects to perform salvage operations.

[0036] Furthermore, the system also includes a tilt angle sensor (e.g., installed below the deck near the center of gravity of the cleanup vessel 2) and a deflection angle sensor (e.g., installed near a fixed component). The tilt angle sensor is used to monitor the tilt angle between the cleanup vessel 2 and the water surface, sensing the hull's rolling state in real time. When the hull develops a dangerous tilt angle due to a sudden change in salvage load or water turbulence, the control system immediately locks all winches and suspends traction to prevent the tilt angle from continuing to increase, thus providing emergency response time and reducing the probability of capsizing in high-velocity environments.

[0037] The deflection angle sensor is used to monitor the deflection angle between the longitudinal traction cable 51 and the axis of the cleanup vessel 2. Once the deflection angle exceeds the set range, the machine will be stopped to avoid uneven stress on the bow and stern of the hull caused by the cable being pulled at an angle, reduce hull structural fatigue and additional cable wear, and ensure that the traction path is always along the centerline of the hull during long-term operation, thus maintaining operational accuracy.

[0038] The following describes the workflow of a cable-stayed salvage system provided in an embodiment of this application.

[0039] The drift barrier 1 first crosses the working channel to intercept floating objects in the water flow, forming a concentrated target salvage area 11. The cleanup vessel 2 is initially moored upstream of the drift barrier 1, waiting for deployment. The floating platform 3 floats upstream of the cleanup vessel 2 and maintains its balance on the water surface through its two side ears 32, reducing the risk of capsizing. The floating platform 3 is connected to the cables of the transverse traction winches 4 on both banks. The cable of the longitudinal traction winch 5 is turned by the guide wheel 61 on the top surface of the floating platform 3, passes through the clamping channel formed by the stop wheel 62 and the guide wheel 61, and connects to the fixing component on the upstream side of the cleanup vessel 2 that matches the hull axis. The curved surface on the upstream side of the floating platform body 31, facing away from the water flow, evenly distributes the impact force of the water flow to maintain a stable posture.

[0040] During the operation, the target salvage area 11, where floating debris is concentrated, is first identified through monitoring. Then, with the coordinated action of the lateral traction winch 4 (extending the cable on one side and retracting the cable on the other), the floating platform 3 and the debris removal vessel 2 are moved along the direction perpendicular to the water flow. Simultaneously, tilt angle sensors monitor the tilt angle of the debris removal vessel 2 relative to the water surface, and deflection angle sensors monitor the deflection angle between the longitudinal traction cable 51 and the axis of the debris removal vessel 2, ensuring the stability of the vessel's attitude. After the debris removal vessel 2 moves directly upstream of the target salvage area 11, the longitudinal traction winch 5 pulls the debris removal vessel 2 longitudinally along the direction parallel to the water flow through the cable, while the lateral traction winch 4 assists in correcting lateral deviations. Throughout the process, the winch actions are dynamically adjusted based on sensor data to avoid exceeding the tilt or deflection angle limits. When the debris removal vessel 2 accurately reaches the target salvage area 11, all traction winches lock the corresponding cables to fix the vessel's position, and the salvage equipment 21 on the downstream side of the debris removal vessel 2 is then activated to complete the grabbing and collection of floating debris. After the salvage operation is completed, the cleanup vessel 2 will be moved to the unloading yard 7 on the shore by the coordinated control of the transverse traction winch 4 and the longitudinal traction winch 5 to carry out the unloading operation, so as to carry out the next salvage mission.
