Description

Technical Field

[0001] This invention belongs to the field of floating breakwaters, specifically relating to a rapid emergency support floating breakwater based on dynamic positioning and its erection method. Background Technology

[0002] my country has numerous coastal ports of varying sizes, and the sea conditions are complex. In particular, frequent typhoon activity in summer poses a significant threat to port infrastructure and berthed vessels. Therefore, constructing wind and wave protection facilities suitable for each port is crucial, and their layout and type have a profound impact.

[0003] A floating breakwater is a type of breakwater consisting of wave-damping buoys and anchorages, utilizing the buoys to prevent wave propagation. However, existing floating breakwater technology suffers from severe heaving and rolling motions of the buoys in high sea states, resulting in ineffective wave-damping and even causing adjacent breakwater modules to collide and break, as well as anchor chains to snap. Furthermore, existing floating breakwater technology is cumbersome, has fixed and inflexible dimensions, and offers limited wave-damping performance, making it difficult to quickly erect and effectively prevent wave propagation for port protection. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to propose a dynamic positioning-based rapid erection method for emergency floating breakwaters, enabling rapid erection in emergency situations and maximizing the protection of port infrastructure and berthed vessels.

[0005] The technical solution of the present invention:

[0006] A rapidly erectable emergency support floating breakwater based on dynamic positioning includes a resonant wave damping system, a buoyancy positioning box, a modular docking section, and a battery compartment.

[0007] The resonant wave-damping box utilizes the Helmholtz resonator principle to make the water inside the chamber resonate with the water outside, thereby making the breakwater module self-stabilized, reducing swaying, and improving wave-damping efficiency.

[0008] Furthermore, the resonant wave-damping box includes a resonant box, a azimuth thruster, vents, a water inlet, a thruster mounting port, and box connecting lugs. The two resonant boxes are longitudinally combined to form a resonant module, which is trapezoidal in shape. The upper surface of the resonant box is provided with several vents for discharging internal gas, and the lower surface of the resonant box is provided with a water inlet for seawater backflow. The interior of the resonant box is a smooth cavity for seawater to resonate with external waves. The box connecting lugs are located at the joints on the upper surface and sides of the resonant box for docking and disassembling between modules. The azimuth thruster is located on the inclined surface of the resonant box for docking and moving the breakwater and resisting wave disturbance.

[0009] The buoyancy positioning box is set between the resonant wave-damping boxes to provide buoyancy for the entire breakwater, and is equipped with a torpedo anchor inside for rapid positioning in a fixed position during waves.

[0010] Furthermore, the buoyancy positioning box includes a buoyancy box, a torpedo anchor, an anchor box cover, a cable box cover, a cable box sealing ring, a winch, and a winch frame. The buoyancy box is trapezoidal in shape, with its mating surface aligned with the resonant wave-damping box, providing buoyancy to the resonant wave-damping box. The torpedo anchor is positioned on both sides of the buoyancy box, with its launch direction vertically downward, for rapid anchoring and positioning in emergency situations. The anchor box cover is positioned on both sides of the upper surface of the buoyancy box for the installation and maintenance of the torpedo anchor. The cable box cover is positioned inside the anchor box cover, working together with the cable box sealing ring to provide a seal for the buoyancy box to prevent water ingress. The winch is positioned inside the buoyancy box for launching and retrieving the torpedo anchor and providing anchor chain tension. The winch frame is positioned below the winch for securing the anchor chain device.

[0011] The module docking section is located at both ends of the breakwater module, and is used to connect two adjacent breakwater modules and enhance the anti-sway capability. It is equipped with a cable tensioning device inside for quick docking and disassembly of the breakwater.

[0012] Furthermore, the module docking section includes a docking box, anti-collision ball pads, docking buckles, and a docking self-locking device. The docking box is located at the front and rear ends of the breakwater module, and its docking surface has several square mounting holes for installing the docking buckles and the docking self-locking device. The anti-collision ball pads are located between two docking boxes and are fastened to the lacing rings of the docking boxes to reduce collisions between the module docking sections. The docking buckles are uniformly located on the square mounting holes on one docking box, and have a rectangular spline hole at the center for the docking self-locking device to engage. The docking self-locking device is uniformly located on the square mounting holes on the other docking box for docking adjacent breakwater modules.

[0013] The battery compartment is located at the bottom of the breakwater module, making its center of gravity lower than its center of buoyancy, thus improving the stability of the breakwater. The battery compartment is used to provide power to the internal devices of the breakwater module.

[0014] Furthermore, the battery compartment is located between the inlets of the resonant wave-damping box and includes a suspension frame, a waterproof battery module, a battery rack, and a waterproof compartment. The suspension frame is located at the bottom of the breakwater module and is used to fix the waterproof compartment. The waterproof battery module is located on the battery rack and is used to provide power to the internal devices. The battery rack is located below the suspension frame and is an angle steel structure with a certain rigidity to position the waterproof battery module and prevent it from shaking. The waterproof compartment has a trapezoidal shape and has a certain wave resistance.

[0015] Furthermore, the buoyancy box includes a sealed chamber, a torpedo compartment, a launch tube, an anchor chain hole, a torpedo hatch, a cable box opening, float docking lugs, and an anchor chain sliding opening. The sealed chamber is located in the middle of the buoyancy box and is used to install the anchor chain winch and provide buoyancy. The torpedo compartment is located on both sides of the buoyancy box and is used to install the torpedo anchor. The launch tube is vertically located in the middle of the torpedo compartment, and the launch port is located on the inclined surface on both sides of the buoyancy box for launching torpedo anchors with rapid positioning function. Fixed cross plates are provided around the launch tube. The anchor chain hole is located on the bulkhead between the sealed chamber and the torpedo compartment for the movement of the anchor chain. The torpedo hatch is located on the upper surface of both sides of the sealed chamber for installing the anchor box cover. The cable box opening is located next to the torpedo hatch and is used to install the cable box cover. The float docking lug is located on the surface of the buoyancy box docking surface for connection and fixation with the box body connecting lug. The anchor chain sliding opening is located at the upper opening of the launch tube and faces the anchor chain hole.

[0016] Furthermore, the docking self-locking device includes a panel, a support plate, a motor, a self-locking device, a winch, a cable, and a docking head. The panel is square with a central hole for the cable to pass through. A mounting plate is provided on the back. The support plate is located below the central hole in the panel and consists of two horizontal and vertical flat plates forming an L-shaped structure. A motor is located on the right side of the vertical plate, and a self-locking device is located above the horizontal plate. The motor provides positive drive for the self-locking device, which drives the winch to rotate. Negative drive will self-lock. The winch is used to wind up and unwind the cable. It has a keyed shaft hole at its axial center for connecting and driving the self-locking device. One end of the cable is wound around the winch, and the other end passes through the central hole in the panel and connects to the docking head. The docking head has retractable hooks for engaging the inner wall of the docking plate, thus connecting the docking parts of adjacent modules.

[0017] A method for erecting the aforementioned emergency floating breakwater is also provided, comprising the following steps:

[0018] Step 1: Based on the different sizes of ports or bays, pre-assemble the resonant wave-damping box, positioning buoyancy box, and module docking part into breakwater modules of different lengths to adapt to the emergency needs of different ports or bays.

[0019] Step 2: Place the pre-installed breakwater module into the water;

[0020] Step 3: Each breakwater module reaches the designated position 1 through the dynamic positioning system. The docking self-locking device of the docking part of the adjacent two modules is released to manually dock them end to end, and each breakwater module forms a breakwater whole.

[0021] Step 4: The buoyancy positioning box located on the left side of each breakwater module launches the torpedo anchor vertically towards the seabed, and the winch located inside the left buoyancy positioning box begins to release the anchor chain.

[0022] Step 5: The breakwater as a whole begins to move laterally to position 2. The buoyancy positioning box located on the right side of each breakwater module launches the torpedo anchor vertically towards the seabed. The winch located inside the buoyancy positioning box on the right side begins to release the anchor chain.

[0023] Step 6: The breakwater begins to move laterally towards target position 3. The winch inside the left buoyancy positioning box begins to retract the anchor chain. Together with the winch inside the left buoyancy positioning box, effective anchor chain tension is formed on both sides, providing reliable anchoring force for the torpedo anchor.

[0024] Step 7: After the emergency support is completed, the winches on both sides of the breakwater module retrieve the anchor chains and torpedo anchors, the docking self-locking device disconnects the two-way docking, and the emergency support floating breakwater module is withdrawn.

[0025] The beneficial effects of this invention are as follows: This invention provides a dynamic positioning-based rapid emergency support floating breakwater and its erection method, which is suitable for nearshore areas with harsh sea conditions. Breakwater modules of suitable length can be pre-installed according to different port sizes. In emergency situations, it can autonomously reach the designated area and quickly dock and erect. Through its own resonant structure, dynamic positioning system, and torpedo anchor, it can effectively prevent waves and reduce waves, providing safety for firefighters and coastal infrastructure. Moreover, it has a simple structure, low maintenance cost, strong applicability, broad market demand, and good economic value. Attached Figure Description
