Description

Technical Field

[0001] This invention belongs to the field of floating breakwater splicing technology, specifically relating to a flexible support rope connection device and splicing method between floating breakwater modules. Background Technology

[0002] A floating breakwater is an engineering facility used to protect water structures such as ports and coastlines. It typically consists of a series of floating modules that can be connected to form a continuous breakwater system, thereby mitigating the impact of waves and protecting ports, docks, and other coastal structures from damage.

[0003] Traditional floating breakwater structures in large-scale marine engineering projects often employ modular designs. However, existing modular connection devices have several problems in dealing with wave impacts. For example, rigid connection devices have a short service life and are prone to structural deformation and cracking due to long-term wave impacts, ultimately leading to breakwater module connection failure and reduced wave-damping stability. Furthermore, traditional connection devices lack the energy-absorbing and buffering capacity to cope with impacts in extreme sea conditions, making them susceptible to severe damage. Summary of the Invention

[0004] The purpose of this invention is to address the limitation of the reliability of connection devices in the prior art under wave impact and extreme sea conditions. This invention provides an elastic support rope connection device and assembly method between floating breakwater modules.

[0005] Technical solution of the present invention:

[0006] A flexible support rope connection device for floating breakwater modules includes an elastic support device and a self-locking device. The elastic support device is located within the module docking section at one end of the floating breakwater and is used to deploy and retract the self-locking device. The self-locking device is located at the end of a flexible cable and is used to connect adjacent floating breakwater module units. This invention is applicable to the interconnection of floating breakwater module units. By incorporating elastic components, the elastic support device allows for single-degree-of-freedom elastic movement within the module docking section, preventing rigid damage caused by relative movement between breakwater module units, ensuring the reliability of the connection between floating breakwater module units, and improving the wave-damping performance of the floating breakwater. Wherein:

[0007] The elastic support device includes a self-locking base, a motor, a self-locking device, a coupling, a winch pulley, a spring, a spring pressure plate, a spring limiting cylinder, a panel, and a cable. The motor is mounted on the motor mounting hole of the self-locking base. The self-locking device is located inside the self-locking base, with its input shaft connected to the motor via a coupling. Its output shaft has a winch pulley wound with several lengths of flexible cable. The self-locking device drives the winch pulley to rotate and has a reverse transmission self-locking function. The spring's head is located on the outside of the square plate of the self-locking base, and its tail is... On the inner side of the panel, tension and elastic force are provided for the self-locking fixing seat to move in a single degree of freedom. The spring is fixed at both ends and is integrally set in the spring limiting cylinder. The spring pressure plate has a semi-circular structure with mounting holes at both ends for fixing the spring. One end of the spring limiting cylinder has a mounting seat for mounting on the panel and for limiting the radial torsion of the spring. The side of the spring limiting cylinder has a rectangular opening wide groove for the motor to slide in the groove with the self-locking fixing seat. The cable passes through the elliptical hole of the self-locking fixing seat and the panel and the middle of the spring.

[0008] The self-locking mounting base includes a force-bearing plate, an L-shaped support plate, an elliptical rope hole, a motor mounting port, and a self-locking device mounting hole. The force-bearing plate is square and is located at both ends of the L-shaped support plate to bear the spring force and install the spring pressure plate. The bottom of the vertical surface of the L-shaped support plate has a motor mounting port for installing the motor. The elliptical rope hole is located in the middle of one side of the force-bearing plate for the cable to pass through. The self-locking device mounting hole is located on the horizontal surface of the L-shaped support plate for installing the self-locking device.

[0009] The spring has triangular pressure feet at both ends, which are used to constrain the outside of the force-bearing plate.

[0010] The connecting buckle plate is square and is installed at the docking part of the target floating breakwater. It has a round hole in the center and several rectangular grooves on the circumference of the round hole for connecting with the self-locking device.

[0011] The self-locking connection device includes a biting head, a top ring, a cable restraint head, a top tooth, a biting tooth, a tooth-to-tooth rod, and a top tooth pin. The biting head is a sphere with an internally threaded shaft at one end, and has several tooth grooves and sliding grooves. The top tooth is set in the sliding groove of the biting head. The top ring is set on the internally threaded shaft of the biting head. The cable restraint head has an external thread and is installed in conjunction with the internally threaded shaft of the biting head to limit the displacement distance of the top ring. The biting tooth is shaped like an animal tooth, with a pin hole at its root, and is assembled into the tooth groove of the biting head by the top tooth pin. Its head has a flat surface for biting contact with the inner surface of the mating buckle plate. The inner bend of the biting tooth also has a collar for connection. The tooth-to-tooth rod has pin holes at both ends, and is connected to the front end of the top tooth and the inner bend of the biting tooth by pins respectively.

[0012] The outer surface of the top ring is knurled to increase rotational friction. The tail end of the top tooth is provided with an incomplete thread for fitting and installing with the top ring. The axial displacement of the top ring is restricted by the cable restraint head. When the top ring rotates, the meshing threads push the top tooth forward in the groove of the biting head, thereby driving the inter-tooth rod to push the biting tooth to open outward.

[0013] Furthermore, a splicing method is also provided, including the following steps:

[0014] Step 1: Deploy the floating breakwater into the target water area and pre-adjust the docking attitude of adjacent floating breakwater modules;

[0015] Step 2: Start the motor in the elastic support device to drive the self-locking device in the forward direction, so that the winch pulley releases a certain length of flexible cable;

[0016] Step 3: Rotate the top ring in the opposite direction to retract the top teeth, causing the bite teeth to retract inward, and then assemble the self-locking device into the docking buckle plate of the target breakwater module.

[0017] Step 4: Rotate the top ring in the forward direction so that the top teeth push upward, causing the bite teeth to open and snap onto the inner side of the mating plate, while the top ring presses against the outer side of the mating plate;

[0018] Step 5: Start the motor in the elastic support device to drive the self-locking device to rotate, so that the winch pulley retracts the flexible cable and pulls the adjacent floating breakwater modules that have been connected together.

[0019] The beneficial effects of this invention are as follows: This invention provides an elastic support rope connection device and splicing method between floating breakwater modules. By setting an elastic device within the joint of the floating breakwater, the connection device can generate a single degree of freedom displacement under the action of waves, avoiding deformation and breakage of the connection device caused by relative movement between breakwater modules, thus preventing connection failure and reduced wave-damping reliability. Simultaneously, in extreme sea conditions, it can absorb the impact between breakwater modules, acting as a buffer. This extends the service life of the connection device, ensuring the wave-damping reliability of the floating breakwater, and has good market demand and economic benefits.
