Description

Technical Field

[0001] The invention relates to the technical field of wave reduction, and in particular to a wave reduction device and method based on the liquid shock absorption principle. Background Art

[0002] Against the backdrop of increasing global energy demand, the extraction and transportation of oil and gas are becoming increasingly frequent. These activities involve the use of special ships and marine structures, such as transport vessels with liquid tanks and moon pool structures. These structures are usually designed as bottom-closed or non-closed hulls to store and transport large amounts of liquid resources. This type of design is indispensable in modern marine engineering to ensure the effective transportation and extraction of natural gas and oil.

[0003] However, these hull structures face many challenges in the marine environment. Due to the constant impact of waves and the movement of the ship itself, the liquid in the hull will produce violent fluctuations. This fluctuation not only increases the difficulty of marine engineering operations, but in some cases, wave slamming may cause damage to the hull structure, further affecting the stability and safety of the ship. Wave kinetic energy is mainly concentrated near the water surface, making methods to control and slow down this energy particularly important.

[0004] In existing technologies, these hulls and structures are usually designed with closed or open bottoms to adapt to different engineering needs and marine environments. The design of the hull allows them to operate in complex marine environments, including stable floating and load-bearing in open waters. The development and application of these technologies have largely supported the success and safety of marine engineering projects.

[0005] However, a significant problem with these hull structures is that they are often exposed to the violent marine environment and ship motion, resulting in extremely violent wave motion inside the hull. This internal fluctuation not only affects the normal operation of marine engineering, but may also cause damage to the structure due to wave slamming. In addition, the wave energy is mainly concentrated near the wave surface, which makes the bottom structure particularly vulnerable to impact and damage. Although existing solutions can alleviate these problems to a certain extent, they still fail to provide an economical and effective way to comprehensively reduce the risks and damage caused by such waves. Summary of the invention

[0006] In view of the deficiencies of the prior art, the present invention provides a wave reduction device based on the liquid shock absorption principle, which solves the problem that the prior art still fails to reduce the impact and damage of the waves while reducing the waves.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A wave reduction device based on the liquid shock absorption principle, comprising:

[0009] A plurality of floating balls, wherein the plurality of floating balls are connected by chains, connecting pieces are hinged on both sides of the floating balls, and chains are arranged between the connecting pieces;

[0010] The float has planes on both sides, and the plane surfaces are provided with a plurality of flow holes. A reduction mechanism is arranged inside the float for reducing the seawater poured in from the flow holes. A sensor unit is arranged inside the float.

[0011] Furthermore, the float is provided with a baffle plate which is spirally distributed inside the float.

[0012] Furthermore, the inner ring of the baffle plate is provided with an inner chamber, the inner chamber is located at the center of the float, and a plurality of cavities are opened on the surface of the baffle plate and the inner chamber.

[0013] Furthermore, the reduction mechanism is arranged inside the inner chamber, and comprises a non-Newtonian liquid and gravel, wherein the non-Newtonian liquid and the gravel are in contact with each other, and different floats are provided with non-Newtonian liquid and gravel of different weights and proportions.

[0014] Furthermore, the connecting member includes a rotating shaft, which is fixed on the float, and the surface of the rotating shaft passes through and is rotatably connected to a central rotating shaft, a connecting seat is provided at the bottom of the central rotating shaft, and the bottom of the central rotating shaft rotates inside the connecting seat, a U-shaped fixing member is hinged on the upper surface of the connecting seat, the rotating shaft is fitted with the connecting seat, and the U-shaped fixing member is connected to the chain.

[0015] Furthermore, a block is fixedly connected to one side of the plane, and the block is arranged above the flow hole.

[0016] Furthermore, the sensing unit includes a pressure sensor, an accelerometer and a data processing module, which are used to collect and analyze seawater wave information, and transmit the analysis results to a remote monitoring system through a wireless communication module to achieve real-time monitoring of various seawater properties.

[0017] On the other hand, the present invention also provides a wave reduction method based on the liquid shock absorption principle, based on the above-mentioned wave reduction device based on the liquid shock absorption principle, comprising the following steps:

[0018] Step 1, filling the inner chamber with non-Newtonian liquid and gravel;

[0019] Step 2: Set the connection order of the floats and connect them using chains;

[0020] Step 3: Connect in series and place on the sea;

[0021] Step 4: The waves hit the buoy, and the seawater flows into the buoy through the flow holes. At the same time, blocking can turn back some of the waves;

[0022] Step 5: The seawater poured into the float flows along the texture of the baffle plate into the middle of the float;

[0023] Step 6: The seawater is decelerated by mixing with the non-Newtonian liquid and gravel;

[0024] Step seven, the wave reduction is completed by injecting seawater and then pushing out the internal seawater.

[0025] Furthermore, in step 2, a plurality of lighter floats are placed in the middle, and heavier floats are placed on both sides.

[0026] Furthermore, the weight of the float can be balanced according to the non-Newtonian liquid and gravel.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The present invention uses an internal reduction mechanism, especially the combination of non-Newtonian liquid and gravel, so that the device can effectively absorb and dissipate wave energy. Non-Newtonian liquids show increased viscosity when under pressure, which increases the resistance of the water flow and effectively slows down the speed and kinetic energy of the waves. The present invention uses the float, chain and the counterweight of the float to allow the float to have room for movement and swing back and forth to reduce energy. At the same time, it can also dump out the seawater that is filled in. The counterweight of the float itself prevents the float from tipping over. 3. The present invention enhances the overall stability of the system by strategically configuring heavier and lighter floats, especially in complex or changing ocean conditions. This configuration helps to maintain the balance and functionality of the device and prevent structural damage in extreme environments.

[0029] 4. The present invention takes environmental impact into consideration through the materials used and the design methods, aiming to reduce disturbance to the marine ecosystem. Non-Newtonian liquids and natural gravel are relatively friendly to marine life, and the operation of the device does not involve the discharge of harmful chemicals.

[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example 1

[0039] Please see attached Figure 1 -Attached Figure 4 The embodiment of the present invention provides a wave reduction device based on the liquid shock absorption principle, comprising:

[0040] Float design: Each float 1 is spherical, with two sides cut into planes, and multiple flow holes 4 are designed on the plane for the entry and exit of seawater. Connectors are hinged on both sides of the float, and connected to adjacent floats 1 through chains 3 to form a series of flexibly configurable floating structures. A reduction mechanism is provided inside the float 1, specifically including non-Newtonian liquid 7 and gravel 8, which are used to absorb and reduce the kinetic energy of seawater. The block 2 is used to return the waves. When the waves hit the surface of the float 1, the waves follow the arc of the block 2 to return the waves, and a plurality of dense holes are opened on the surface of the float 1, which are evenly distributed in the lower half of the float 1 for the return of seawater.

[0041] The connecting part includes a rotating shaft 11, which is fixed on the float 1. A central rotating shaft is penetrated through the surface of the rotating shaft 11 and is rotatably connected thereto. A connecting seat 10 is provided at the bottom of the central rotating shaft, and the central rotating shaft rotates inside the connecting seat 10. A U-shaped fixing part 12 is hinged on the upper surface of the connecting seat 10. The rotating shaft 11 fits the connecting seat 10. The U-shaped fixing part 12 is connected to the chain 3. A baffle plate 5 is provided inside the float 1. The baffle plate 5 is used for guiding flow, and a plurality of dense holes are opened on the surface. The baffle plate 5 is spirally distributed inside the float 1.

[0042] By using a rotatable connector at the connection between the float and the chain, the float has room for movement. The connector includes a rotating shaft fixed on the float, which passes through and rotates to connect the central shaft. A connecting seat is provided at the bottom of the central shaft. A U-shaped fixing piece is hinged on the upper surface of the connecting seat. The U-shaped fixing piece is connected to the chain, so that the float can swing freely under the impact of waves, reduce wave energy, and dump out the seawater poured into the float at the same time. The spiral baffle inside the float guides the seawater to flow and discharge through the flow hole, effectively reducing the internal water accumulation. The float's own counterweight prevents excessive dumping, ensuring the reduction effect and device stability. This design improves the stability of the float and the wave reduction effect, reduces energy through active swinging and reasonably diverts seawater, enhances the overall performance of the device, and provides a safer and more efficient solution for offshore operations.

[0043] Mitigation mechanism: A baffle 5 is arranged inside the float, which is spirally distributed to guide the flow of seawater and increase the length of the flow path to increase the contact time and effect between seawater and non-Newtonian liquids and gravel. The inner circle of the baffle is provided with an inner chamber 6, located at the center of the float, and a plurality of cavities 9 are opened on its surface to further control the water flow.

[0044] Functions of non-Newtonian liquid 7 and gravel 8: non-Newtonian liquid 7 and gravel 8 are attached and distributed inside inner chamber 6. The rheological properties of non-Newtonian liquid 7 make it more viscous when impacted, thereby increasing resistance and slowing down the speed and kinetic energy of seawater. Gravel 8 increases the turbulence of the fluid and improves the energy dissipation efficiency.

[0045] The design of the chain 3 and the buoy 1 enables the entire structure to flexibly adapt to different marine environments. It can float alone or be connected to each other through the chain 3 to form a larger floating structure. Such a design not only improves the stability of the entire system, but also enables it to play a greater role in different marine environments.

[0046] Inside the buoy 1, the baffle 5 is designed to cleverly guide the seawater into the inner chamber, and by increasing the flow path length, the seawater is in contact with the non-Newtonian liquid 7 and gravel 8 for a longer time, thereby achieving a better energy dissipation effect. The combination of non-Newtonian liquid 7 and gravel 8 makes the entire reduction mechanism perform well in absorbing and reducing the kinetic energy of seawater, effectively protecting the marine ecological environment.

[0047] Real-time collection and analysis of seawater wave information is achieved by setting up sensing units, including pressure sensors, accelerometers and data processing modules. The pressure sensor is used to measure the pressure change of seawater on the buoy to obtain the height and intensity information of the waves; the accelerometer is used to measure the acceleration and direction change of the movement of the buoy to obtain the frequency and waveform information of the waves. The data processing module receives and processes these data, performs filtering, analysis and feature extraction, and then transmits the processed wave information to the remote monitoring system through the wireless communication module to achieve remote data monitoring and system adjustment. This design brings multiple beneficial effects: it realizes real-time monitoring and early warning of wave conditions to ensure the safety of offshore operations; by accurately analyzing wave characteristics, dynamically adjusting the working state of the buoy to optimize the wave reduction effect; predicting and reducing the impact of waves on equipment, improving equipment durability and stability; and through remote management and control, improving management efficiency and reducing maintenance costs.

[0048] In addition, the design of the float 1 also takes environmental protection and sustainability into consideration. In terms of material selection, corrosion-resistant and wear-resistant environmentally friendly materials are used, specifically fiberglass, which is also called fiber reinforced plastic. This material is composed of plastic resin and reinforced glass fiber, providing excellent corrosion resistance and mechanical properties. The wear resistance of fiberglass makes it suitable for use in harsh marine environments, and the material is light in weight and easy to install and maintain; ensuring that the float 1 will not pollute the environment during long-term use. At the same time, the design of the float 1 also takes into account the survival needs of marine life and will not cause harm to marine life.

[0049] Specifically, this embodiment can reduce waves through the following three situations:

[0050] 1. Energy wave reflection

[0051] The device adopts a floating ball 1 design, each of which is spherical and has planes and multiple flow holes on both sides for the inflow and outflow of seawater. The two sides of the floating ball 1 are connected to the chain 3 through hinged connectors to form a floating structure with flexible configuration. The surface of the floating ball is designed with multiple dense holes, evenly distributed in the lower half of the floating ball, for the return of seawater. When the wave hits the surface of the floating ball, the wave is reflected back along the blocking arc on the floating ball, thereby effectively reducing the kinetic energy of the wave.

[0052] 2. Gap friction energy consumption

[0053] A reduction mechanism is provided inside the float 1, including a non-Newtonian liquid 7 and gravel 8, which are used to absorb and reduce the kinetic energy of seawater. The rheological properties of the non-Newtonian liquid 7 make it more viscous when impacted, increasing resistance and slowing down the speed and kinetic energy of seawater. The gravel 8 further improves the energy dissipation efficiency by increasing the turbulence of the fluid. In addition, the spiral baffle 5 inside the float 1 guides the flow of seawater and discharges it through the flow hole, effectively reducing internal water accumulation and increasing the contact time and effect of seawater and the reduction material, thereby achieving a better energy dissipation effect.

[0054] 3. The ball shakes back and forth and turns into kinetic energy

[0055] The connection between the buoy 1 and the chain 3 adopts a rotatable connector, so that the buoy 1 has room for movement. The connector includes a rotating shaft 11 fixed on the buoy 1, and the rotating shaft 11 penetrates and rotates to connect the central rotating shaft. A connecting seat is provided at the bottom of the central rotating shaft. The upper surface of the connecting seat 10 is hinged to a U-shaped fixing member 12, and the U-shaped fixing member 12 is connected to the chain 3. In this way, the buoy 1 can swing freely under the impact of waves, converting the wave energy into the shaking kinetic energy of the buoy 1, and at the same time dumping out the seawater poured into the buoy 1. The counterweight design of the buoy 1 itself prevents excessive dumping, ensuring the reduction effect and the stability of the device.

[0056] The device effectively absorbs and reduces the kinetic energy of seawater through the above three principles, protects the marine ecological environment, and adapts to different marine environments to achieve flexible configuration. In addition, the device uses corrosion-resistant and wear-resistant fiberglass materials to ensure environmental protection and sustainability. The overall design enhances the stability of the device and the wave reduction effect, providing a safer and more efficient solution for offshore operations.

[0057] Example 2

[0058] This embodiment provides a wave reduction method based on the liquid shock absorption principle, comprising the following steps:

[0059] Step 1: Filling process

[0060] First, we need to fill the inner chamber 6 of the device with non-Newtonian liquid 7 and gravel 8. Non-Newtonian liquid has special rheological properties and can show viscoelasticity when subjected to shear force, thereby effectively absorbing and dispersing the energy of waves. Gravel plays a role in increasing internal resistance, making the device more stable when facing strong waves.

[0061] Step 2: Float Configuration

[0062] Next, the connection order of the buoys needs to be set according to the required stability and shock absorption effect. The lighter buoys are placed in the middle, while the heavier buoys are placed on both sides and connected by chains 3. This configuration ensures that the lighter buoys are pushed to a certain distance under the action of waves, but due to the pulling force of the heavier buoys on both sides, the buoy in the middle will not be pushed too far, thereby preventing damage to nearby ships or creatures.

[0063] Step 3: Deployment and Application

[0064] After the configured buoys 1 are connected in series, they are placed in the target area at sea. When the waves hit the buoys 1, the lighter buoys 1 will be impacted first and pushed to a certain distance. However, due to the pulling force of the heavier buoys 1 on both sides, the middle buoy 1 will be quickly pulled back to its original position, which can effectively reduce the potential threat of the buoys 1 to the surrounding environment.

[0065] Step 4: Interaction between waves and buoys

[0066] During the interaction between waves and the buoy 1, seawater will flow into the buoy through the flow hole 4. At this time, the block 2 will play an important role, which can block and turn back part of the waves, thereby reducing the direct impact of the waves on the buoy 1. This design not only enhances the stability of the device, but also further improves the efficiency of dissipating wave energy.

[0067] Step 5: Internal reduction process

[0068] The seawater poured into the buoy 1 flows to the central inner chamber 6 under the guidance of the baffle 5. Here, the seawater is mixed with the non-Newtonian liquid 7 and gravel 8, and is decelerated by physical action. Finally, the decelerated seawater is discharged from the outside of the device through the cavity 9, thereby completing the wave energy reduction process. As the seawater is continuously poured in and discharged, the device can continuously reduce the wave energy.

[0069] Step 6. Advantages and adjustability of the device

[0070] The wave reduction device effectively increases the flow resistance and path complexity of seawater through advanced design and material selection, significantly improving the efficiency of wave energy dissipation. In addition, the modularity and adjustability of the system enable it to be flexibly configured and adjusted according to specific ocean conditions and needs. This allows the device to maintain high stability and reduction effects when dealing with waves of different intensities and frequencies.

[0071] In summary, this wave reduction device plays an important role in protecting offshore facilities, ships and marine life through its unique design and working principle. With the continuous development of the field of marine engineering, it is believed that this device will be more widely used and promoted in the future.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
