Description

Technical Field

[0001] This utility model relates to the field of wave protection and disaster reduction and coastal engineering equipment technology, and in particular to a high-efficiency floating wave-dissipating device. Background Technology

[0002] In the prior art, patent application number 201510191119.6, entitled "A Simple Floating Wave-Dissipating Device," provides a floating wave-dissipating device. This device consists of multiple baffles forming multiple wave-dissipating chambers, which progressively eliminate wave energy. However, this device has the following drawbacks: 1. The entire wave-dissipating device floats on the water surface, resulting in a weak effect on eliminating wave energy in the water; 2. The wave-dissipating device has a complex structure, and its wave-dissipating effect is affected if the internal baffles are damaged or the chambers are blocked. Floating breakwaters are wave-dissipating devices that float on water, offering advantages such as easy disassembly and installation, and high flexibility. However, most current floating breakwaters only float on the water surface, resulting in a weak effect on eliminating energy from waves below the water surface; they are also relatively lightweight, making them prone to tilting and swaying under wave action, exhibiting poor stability, low wave energy dissipation, and low wave-dissipating efficiency.

[0020] This utility model provides a high-efficiency floating wave-damping device. The wave-damping body is equipped with a buoyancy body and a gravity body, with its upper end above the water surface and its lower end below the water surface, at a depth of no less than 1 / 3 of the water depth. This eliminates the energy of waves both above and below the water surface. The specific gravity of the wave-damping body is 0.7–0.9, and its weight is no less than 100 kg per meter.

[0034] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper," "lower," "front," and "rear" are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference.

[0035] This invention provides a high-efficiency floating wave-damping device. By adding a gravity element to increase the weight of the device, the inertia of the floating wave-damping device is increased, thus improving its stability. This stability makes the breakwater less prone to tilting or overturning under wave action, enabling it to more effectively resist wave impact. The increased weight of the wave-damping device results in a smaller range of motion under wave action, meaning it can better maintain its predetermined position, reducing the impact of waves and thereby improving energy dissipation efficiency.

[0036] Specifically, this utility model provides a high-efficiency floating wave-damping device, comprising a buoyancy body, a connecting device, a gravity body, and a fixing device. The connecting device connects the buoyancy body and the gravity body to form a wave-damping body. The wave-damping body floats in the water, and through the arrangement of the buoyancy body and the gravity body, when the device is placed in the water, the upper end of the entire wave-damping body is 10-100cm above the water surface, and the lower end is below the water surface, with a depth of not less than 1 / 3 or more of the water depth. The specific gravity of the wave-damping body is 0.7-0.9, which is less than the specific gravity of water, so it is in a floating state in the water. The fixing device connects the bottom of the water and the wave-damping body to fix the wave-damping body in the water, so that the entire wave-damping device is in a stable floating state in the water.

[0037] In a preferred embodiment, the buoyancy body can be a cylinder or prism with a streamlined design to reduce wave resistance, and a splash guard can be added to the top to enhance the wave-dissipating effect.

[0038] In a preferred embodiment, the gravity body is a cylinder or prism made of a high-density material, such as a concrete block, cast iron, or a steel box filled with sand and gravel. The gravity body is used to provide a downward pull to keep the device vertically stable while lowering the center of gravity.

[0039] In a preferred embodiment, the connecting device is a chain, strap, or buckle that secures the buoyancy body and the gravity body together.

[0040] In a preferred embodiment, the connecting device may employ a shell that encloses the buoyancy body and the gravity body together. Furthermore, the shell may be cylindrical or prismatic in shape, with the prismatic shape being a flat cuboid; the shell may be made of rigid materials such as PVC, HDPE, or stainless steel, or flexible materials such as PVC-coated fabric or geotextile.

[0041] In a preferred embodiment, the fixing device includes an anchor and a connecting rope. One end of the connecting rope is fixedly connected to the high-efficiency floating wave-damping device, and the other end is connected to the anchor or pile foundation, which is located on the bottom of the water. The anchor is a helical anchor, a gravity anchor, or a towed embedded anchor. The connecting rope is a polyester cable, a steel wire rope, a nylon rope, or an iron chain.

[0042] In a preferred embodiment, the wave-dissipating body is further provided with a tubular body, which can be a sealed structure filled with water; the tubular body can also be a hollow tube, and the tubular body is provided with a water filling valve and a water draining valve. The depth of the wave-dissipating body in the water can be adjusted by the amount of water injected into the tubular body. The water filling and draining operations are simple and the depth of the device in the water can be flexibly controlled.

[0043] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0044] Example 1

[0045] A high-efficiency floating wave-damping device includes a buoyancy body 1, a connecting device 2, a gravity body 3, and a fixing device 4. The buoyancy body 1 and the gravity body 3 are connected by the connecting device 2 to form a single wave-damping body. The buoyancy body 1 provides upward buoyancy, and the gravity body 3 provides downward gravity. The specific gravity of the wave-damping body can be set between 0.7 and 0.9, ensuring that the buoyancy is greater than the gravity. After being placed in water, the wave-damping body floats, with its overall height above the water surface being 10-100 cm. The distance from the bottom of the wave-damping body to the water surface exceeds one-third of the water depth. The fixing device 4 connects the bottom of the wave-damping body to the water, securing the entire wave-damping body in the water, thus ensuring stable floating. Specifically, the buoyancy body can be cylindrical, made of HDPE plastic, with a diameter of 1.2m or 4m. The gravity body provides downward pull to maintain the vertical stability of the device and lowers the center of gravity; it can be a 3m concrete block. 3 The connecting device uses a galvanized steel chain with a length of 6m. The fixing device uses 3 polyester cables (40mm in diameter) and 3 anchors, each with a weight of 15kN. The anchors can be gravity anchors made of concrete blocks. With the above design, the device can float stably on the water, about 80cm above the water surface, with the gravity body located 6m underwater (more than half the water depth, 10m deep), and maintain a low risk of capsizing in waves.

[0046] Example 2

[0047] A high-efficiency floating wave-damping device, the structural diagram of which is shown below. Figure 2 As shown, it includes a buoyancy body 1, a gravity body 3, a shell 5, and a fixing device 4. The biggest structural difference between the wave-damping device in this embodiment and the wave-damping device in Embodiment 1 lies in the form of the buoyancy body and the gravity body. In Embodiment 1, the buoyancy body and the gravity body are two independent structures connected as one unit by a connecting device. In this embodiment, the buoyancy body and the gravity body are mixed in one shell to form a wave-damping body that cannot be separated.

[0048] Specifically, the buoyancy body can be filled with foam material, and the gravity body can be filled with sand and gravel, such as concrete blocks, cast iron, or steel boxes. The foam material and the gravity body can be filled with sand and gravel together and wrapped in the shell 5. An iron chain of fixing device 4 is also connected to the outside of the shell 5, and the other end of the iron chain is connected to the spiral anchor at the bottom of the water.

[0049] The wave-dissipating body of this utility model's high-efficiency floating wave-dissipating device has a weight of no less than 100 kg per meter of length, and its overall density is less than that of water. Before installation in water, the buoyancy body and gravity body need to be connected together to form the wave-dissipating body, which is then placed in the water and transported to the installation location. The wave-dissipating body is then fixed to the anchor on the bottom of the water using a fixing device.

[0050] Example 3

[0051] The high-efficiency floating wave-damping device of this embodiment is shown in the schematic diagram below. Figure 3 As shown, the wave-damping device has a total height of 1.03 meters and includes a buoyancy body 1, a connecting device 2, a gravity body 3, a tubular bladder 6, and a fixing device 4. The buoyancy body 1 is a cylindrical EPS foam with a diameter of 0.51m and a length of 3 meters. The gravity body 3 is a concrete cylinder with a diameter of 0.32m and a length of 3 meters. The buoyancy body is located above the gravity body. The tubular bladder 6 is a sealed PE pipe with a diameter of 0.2m. The upper end of the tubular bladder 6 has a water filling valve, and the lower end has a water drain valve. The PE pipe is 3 meters long and filled with water. The depth of the wave-damping body in the water is adjusted by regulating the amount of water injected into the tubular bladder. The three cylinders—buoyancy body 1, gravity body 3, and tubular bladder 6—are connected by straps to form a single unit that constitutes the wave-damping body. The wave-dissipating body was installed in a lake with a water depth of 1m. The upper end of the wave-dissipating body was 20cm above the water surface, and the lower end was 80cm below the water surface. Each meter weighed 100kg. The wave-dissipating body was fixed by the connecting rope and anchor pile of the fixing device.

[0052] A first wave gauge was installed 15 meters outside the wave-suppression device, and a second wave gauge was installed 5 meters inside the device. The wave height data from both gauges was fed back in real time. The wave gauge is a specialized instrument for measuring wave height, with the water surface height set to 0m. Waves traveling across the water surface can cause fluctuations, resulting in both positive and negative values ​​for the wave height data. In the experiment, one wave gauge was installed inside and one outside the wave-suppression device. The wave-suppression efficiency was obtained by subtracting the internal wave height from the external wave height and then dividing by the external wave height. Data from naturally occurring waves in the lake under a force 5 wind were plotted as a line graph, with time (seconds) on the x-axis and wave height (meters) on the y-axis. Figure 4As shown, according to the wave height gauge data, the maximum wave height is 0.8 meters. After passing through the wave dissipation device, the wave height is reduced to 0.15 meters, with a wave dissipation efficiency of 75%.

[0053] When waves in the water act on the floating wave-damping device of this invention, the upper part of the device, which extends above the water surface, effectively blocks the rise and transmission of the waves. Simultaneously, the lower gravity element provides significant weight, preventing the device from capsizing under wave action and maintaining high stability. Furthermore, the lower part of the device is positioned at half the water depth, effectively eliminating the force of the waves below the surface. Therefore, the energy of the waves in the water is effectively eliminated, resulting in a high wave-damping efficiency.
