Description

Technical Field

[0001] This invention relates to the field of wharf dredging technology, and in particular to a mobile diversion device suitable for dredging and load reduction behind wharves. Background Technology

[0002] In recent years, the construction and development of pile-foundation wharves has reached its peak. Major coastal ports in my country are experiencing siltation problems, leading to damage to the pile foundations, high maintenance costs, and directly impacting the safe operation of the wharves. The implementation of wharf siltation dredging projects has significant socio-economic value in extending the service life of pile-foundation wharves.

[0003] Currently, traditional methods for addressing siltation issues behind wharves include diversion dikes, motorized dredging, cutter suction dredgers, and trailing suction hopper dredgers. These traditional wharf dredging methods often require large dredgers such as cutter suction dredgers or trailing suction hopper dredgers, which are extremely impractical and difficult to implement in the small waters behind wharves. For wharves with severe siltation or large areas behind them, these methods consume significant manpower, resources, and funds, and do not fundamentally solve the problem. After a period of time, silt will re-accumulate, requiring repeated dredging. Existing methods typically involve periodic dredging and load reduction, meaning dredging needs to be carried out at regular intervals, which fails to effectively address the root cause of siltation and load reduction issues behind wharves.

[0004] Therefore, those skilled in the art need to provide a wharf dredging and diversion device that is applicable to different ranges of wharf dredging, highly operable, and low in cost. Summary of the Invention

[0005] The purpose of this invention is to provide a mobile diversion device suitable for dredging and load reduction behind wharves, solving the problems of low operability, high implementation difficulty, and frequent dredging in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This invention discloses a movable flow guiding device suitable for dredging and load reduction behind a wharf, comprising pontoons, a truss platform frame, and multiple flow guiding modules. The multiple truss platform frames are fixedly connected to form a square structure, and the multiple pontoons are fixedly connected to the periphery of the square structure. Multiple worm gears are movably connected inside the truss platform frame, and the flow guiding modules are connected to the worm gears. The overall width of the multiple flow guiding modules connected end to end matches the entire square structure.

[0008] Preferably, a central channel is fixedly connected to the middle of the outer frame of the truss platform. The central channel divides the internal area of ​​the square structure into two flow guiding areas. Multiple worm gears are installed in each flow guiding area and are arranged at equal intervals. The two ends of the worm gears are rotatably connected to the two ends of the outer frame of the truss platform and the central channel. Two sets of flow guiding modules are symmetrically arranged in the two flow guiding areas, and the top of the flow guiding modules is connected to the worm gears.

[0009] Preferably, the flow guiding module includes a frame and a baffle lifting module. The baffle lifting module is connected to the side of the frame. A slider rail is provided on the top of the frame. A worm slider is slidably connected on the slider rail. The worm is embedded inside the worm slider and the worm slider is connected to the worm by threads.

[0010] Preferably, the baffle lifting module includes a flexible baffle, a roller, a roller bearing, and a geared motor. The roller is rotatably connected to the frame via the roller bearing. One end of the roller is connected to the output end of the geared motor. The top end of the flexible baffle is fixed to the roller. The geared motor is installed at one end of the frame and controls the rolling and unfolding of the flexible baffle. Multiple counterweights are installed on the flexible baffle.

[0011] Preferably, the counterweight is divided into a main counterweight and an auxiliary counterweight. The main counterweight is installed at the bottom of the flexible baffle, and the auxiliary counterweight is evenly arranged above the main counterweight.

[0012] Preferably, the auxiliary counterweight is magnetically attached or embedded in the lower part of the flexible baffle.

[0013] Preferably, adjacent frames are connected end to end by lifting rings welded to the ends of the frames.

[0014] Preferably, anchor piles are fixedly connected to the four corners of the outer frame of the truss platform, anchor chains are fixedly connected to the anchor piles, and a winch is connected to the other end of the anchor chain.

[0015] Preferably, the winch is installed on the shoreline or wharf, or on pre-constructed steel pipe piles near the coast.

[0016] Preferably, the two sets of flow guiding modules are arranged in a straight line or a curve.

[0017] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0018] This invention relates to a mobile diversion device suitable for dredging and load reduction behind a wharf. (1) The device uses modular, lightweight, and flexible floating mobile diversion dike modules to construct the diversion dike, solving construction problems in engineering. (2) The frame is used to suspend and fix the flexible baffle. The simple hinged connectors at both ends of the frame facilitate connection with other modules and jointly provide load-bearing stability. (3) The baffle lifting module can adjust the flexible baffle up and down. The bottom of the flexible baffle is equipped with different counterweights to provide stability according to different usage modes and different inflow conditions. (4) The entire device is positioned in the water flow field behind the wharf using anchor chains and winches. The winches are used to control the length of the anchor chains and transfer the hydrodynamic load on the device to the shore and the wharf. It can also be compatible with automatic adjustment of the reverse tidal current. This device can significantly improve the problem of siltation behind the wharf, which is conducive to maintaining the stability of the unloading ditch topography and reducing the frequency and volume of dredging.

[0025] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] like Figure 1-4As shown, a movable flow guiding device suitable for dredging and load reduction behind a wharf includes a pontoon 1, a truss platform outer frame 5, and multiple flow guiding modules 14. The multiple truss platform outer frames 5 are fixedly connected to form a square structure. The multiple pontoons 1 are fixedly connected to the periphery of the square structure. Multiple worm gears 7 are movably connected inside the truss platform outer frame 5. The flow guiding modules 14 are connected to the worm gears 7, and the multiple flow guiding modules 14 are connected end to end, with the overall width matching the entire square structure.

[0027] Specifically, this diversion device, as a floating platform, can be easily relocated by towing or anchoring, thus achieving mobility and making it suitable for different siltation work areas and work ranges.

[0028] A central channel 6 is fixedly connected to the middle of the outer frame 5 of the truss platform. The central channel 6 divides the internal area of ​​the square structure into two flow guiding areas. Multiple worm gears 7 are installed in each flow guiding area and are arranged at equal intervals. The two ends of the worm gears 7 are rotatably connected to the two ends of the outer frame 5 of the truss platform and the central channel 6. Two sets of flow guiding modules 14 are symmetrically arranged in the two flow guiding areas, and the top of the flow guiding module 14 is connected to the worm gear 7.

[0029] like Figure 3 As shown, the flow guiding module 14 includes a frame 2 and a baffle lifting module 12. The baffle lifting module 12 is connected to the side of the frame 2. A slider rail 11 is provided on the top of the frame 2. A worm gear slider 8 is slidably connected to the slider rail 11. The worm 7 is embedded inside the worm gear slider 8, and the worm gear slider 8 is connected to the worm 7 by threads. Specifically, one end of the worm 7 is connected to a motor, which drives the worm 7 to rotate, thereby adjusting the position of the worm gear slider 8.

[0030] The baffle lifting module 12 includes a flexible baffle 3, a roller, a roller bearing, and a reduction motor 13. The roller is rotatably connected to the frame 2 through the roller bearing. One end of the roller is connected to the output end of the reduction motor 13. The top end of the flexible baffle 3 is fixed on the roller. The reduction motor 13 is installed at one end of the frame 2. The reduction motor 13 controls the rolling and unfolding of the flexible baffle 3. Multiple counterweights 4 are installed on the flexible baffle 3.

[0031] The counterweight 4 is divided into a main counterweight and an auxiliary counterweight. The main counterweight is installed at the bottom of the flexible baffle 3, and the auxiliary counterweight is evenly arranged above the main counterweight.

[0032] The auxiliary counterweight is magnetically attached or embedded in the lower part of the flexible baffle 3.

[0033] Specifically, the counterweights are made of lead, iron, or zinc, with different counterweights configured to provide stability depending on the usage mode and incoming flow conditions. When iron is used as the counterweight, magnets are fixed to the surface of the flexible baffle 3 to attract the iron, or a retainer is fixed inside the flexible baffle 3, through which the counterweight is embedded. When the horizontal beam effect is the main principle for reducing siltation and scouring, a large counterweight is placed at the bottom of the flexible baffle 3 to reduce the deformation of the flexible baffle 3 under hydrodynamic action.

[0034] Anchor piles 9 are fixedly connected to the four corners of the outer frame 5 of the truss platform. Anchor chains 10 are fixedly connected to the anchor piles 9. A winch is connected to the other end of the anchor chain 10. The winch is installed on the shoreline or dock, or on a pre-constructed steel pipe pile near the coast.

[0035] Specifically, the winch is used to control the length of the anchor chain and to transfer the hydrodynamic load on the device to the shore and the dock, and can be automatically adjusted to the reverse of the tidal current.

[0036] like Figure 4 As shown, adjacent frames 2 are connected end to end by lifting rings welded to the ends of the frames 2. Specifically, two frames 2 are connected together by U-shaped connectors passing through the lifting ring holes.

[0037] The two sets of flow guiding modules 14 are arranged in a straight line or a curved line. Specifically, the two sets of flow guiding modules 14 are arranged in a symmetrical straight line or a curved line, or in an asymmetrical straight line or a curved line.

[0038] The two sets of flow guiding modules 14 have two working modes. The first mode is the beam flow flushing mode, in which both sets of flow guiding modules 14 deploy flexible baffles 3, arranged in a straight line or a curved line to constrain the incoming flow, allowing it to accelerate through the narrow gap formed by the flexible baffles 3 of the two sets of flow guiding modules 14, thereby increasing the flow velocity. The second mode is the pick flow flushing mode, in which the baffle lifting module 12 controls one side of the flow guiding module 14 to roll up and retract the flexible baffle 3 to avoid blocking the water, while the other side of the flow guiding module 14 deploys the flexible baffle 3, arranged in a straight line to intercept the incoming flow, working on the principle of pick flow to achieve a local silt reduction and flushing effect.

[0039] The usage process of this invention is as follows:

[0040] After the construction of the pile foundation wharf, the water flow dynamics are weakened due to the obstruction of the pile group, resulting in siltation within the pile foundation, which seriously affects the structural stability of the pile foundation wharf and may even cause the wharf to malfunction. This invention uses multiple floating diversion modules 14 connected end to end, and uses anchor chains 10 deployed on the shore and wharf and winches to control their specific shape and position in the waters behind the wharf, to achieve siltation reduction and scouring effects mainly through diversion or flow diversion, so as to maintain the topographic stability of the unloading ditch and reduce the frequency and volume of dredging.

[0041] In use, firstly, for the identified key areas of siltation, the working area and scope of the floating diversion platform are determined. After the floating diversion platform is towed into place, the anchor chain 10 is positioned by a winch fixed to the positioning steel pipe piles or other anchoring systems installed on the shore and at the dock or behind the dock. Secondly, multiple diversion modules 14 are positioned and connected. Then, the position of the worm slider 8 is adjusted by driving the worm 7 with a motor, thereby controlling the angle and shape of the diversion modules 14. Finally, according to actual needs, two sets of diversion modules 14 are selected to be in either the jet slugging mode or the jet slugging mode. The flexible baffle 3 is deployed and rolled by the reduction motor 13 to achieve the diversion function.
