Description

Technical Field

[0001] The invention belongs to the technical field of marine engineering facilities and relates to an adaptive floating breakwater suitable for complex sea conditions. Background Art

[0002] With the growing demand for renewable energy, the development and utilization of the ocean is imperative. Among many marine equipment, breakwaters are widely used as a hydraulic structure that can defend against wave invasion and form a sheltered water area. Breakwaters are divided into bottom-seated breakwaters and floating breakwaters. Compared with traditional bottom-seated floating breakwaters, floating breakwaters have more significant advantages. Floating breakwaters are easy to construct, install and disassemble, have good economy, are deployed in a wide sea area, are not restricted by water depth, and have strong adaptability. Therefore, floating breakwaters have become a widely used equipment in marine development equipment in recent years.

[0003] A Chinese patent (publication number: CN117779684A) discloses a floating breakwater for an offshore photovoltaic power plant. The present invention provides a floating breakwater for an offshore photovoltaic power plant and a construction method, which can fully protect the offshore photovoltaic equipment by adjusting the posture of the pontoon as a whole, and the adjustment flexibility is high; in the device, the offshore photovoltaic equipment can be fully protected by adjusting the posture of the pontoon as a whole, and the adjustment flexibility is high, but the device mainly protects the photovoltaic equipment by adjusting the posture of the pontoon, but the sea conditions it copes with are relatively single; therefore, an adaptive floating breakwater suitable for complex sea conditions is proposed to solve the above-mentioned problems. Summary of the invention

[0004] In view of the above problems, the purpose of the present invention is to propose an adaptive floating breakwater suitable for complex sea conditions. By automatically adjusting its own draft and floating posture, it can always maintain the best wave-breaking effect and effectively protect marine facilities from waves. It solves the problem that traditional breakwaters are usually fixed structures with fixed draft and structural posture, making them difficult to adapt to complex and changeable sea conditions.

[0005] The technical solution of the present invention is: the adaptive floating breakwater suitable for complex sea conditions described in the present invention comprises a wave system, a buoy, an anchoring system, a control center, a draft depth adjustment mechanism and a floating body attitude adjustment mechanism, etc.;

[0006] A draft depth adjustment mechanism is installed at the bottom of the wave system, and the draft depth adjustment mechanism includes a base fixed at the center position of the bottom of the wave system, a water pump is fixed inside the base, a main delivery pipe is fixed at the water outlet of the water pump, and water pressure sensors are fixedly installed at the four corners of the bottom of the wave system.

[0007] Furthermore, at least six floating body attitude adjustment mechanisms are evenly distributed at the bottom of the wave system, and the floating body attitude adjustment mechanism includes a connection frame fixedly arranged at the bottom of the wave system, a matching hydraulic cylinder is fixedly arranged inside the connection frame, and a stabilizing fin is connected to the driving end of the hydraulic cylinder;

[0008] Flanges are installed on the driving end of the hydraulic cylinder and the top of the adjacent stabilizing fin, and the two flanges are connected by fastening bolts.

[0009] Furthermore, a mounting cavity is provided at the top inner side of the connection frame, and an oil storage tank and a hydraulic pump penetrating each other are fixedly provided inside the mounting cavity.

[0010] Furthermore, a hydraulic pipe passing through the hydraulic cylinder is arranged at one end of the hydraulic pump, and a hydraulic valve is fixedly arranged on the outer surface of the hydraulic pipe;

[0011] An oil return pipe is connected between the hydraulic cylinder and the oil storage tank, and a filter is installed inside the oil return pipe.

[0012] Furthermore, the wave system adopts a modular design and is composed of a plurality of wave floating piles;

[0013] A ballast water cavity is provided inside each of the wave floating piles, a diversion pipe is fixedly connected between the main delivery pipe and each of the ballast water cavities, and a valve is fixedly installed on the outer surface of each of the diversion pipes.

[0014] Furthermore, a group of floating bags are fixedly installed around the wave system, each group of floating bags is composed of a plurality of floating bags, and the bottom of each group of floating bags is lower than the bottom of the wave system.

[0015] Furthermore, a wind direction sensor, a wave height sensor and a control center are fixedly installed on the top of the wave system, and a flow velocity sensor is fixedly installed on the side of the wave system;

[0016] The flow velocity sensor, wind direction sensor, wave height sensor and water pressure sensor are connected to the control center via a wireless signal module.

[0017] Furthermore, the control center is connected to the water pump, the hydraulic valve, the hydraulic cylinder and the hydraulic pump.

[0018] Furthermore, the wave floating pile is made of fiber-reinforced composite material;

[0019] Anchoring systems are also installed at the four corners of the wave system. The anchoring system uses high-strength corrosion-resistant cables, one end of which is connected to anchoring points evenly distributed around the bottom of the wave system, and the other end is fixed to a preset anchor on the seabed.

[0020] Furthermore, the stabilizing fins are made of high-strength, corrosion-resistant metal material.

When facing complex sea conditions, the draft depth and floating body attitude of the breakwater can be adjusted quickly and accurately according to the sensor data and the instructions of the control center; when the wave height increases, the draft depth can be instantly deepened to enhance the stability and wave-breaking ability; when the water flow direction changes or the force of the waves causes the breakwater to roll and pitch, the floating body attitude adjustment mechanism can flexibly adjust the angle and extension length of the stabilizing fins to effectively offset the torque, ensure that the breakwater always maintains a stable attitude, and continuously achieves an efficient wave-breaking effect; in contrast, other devices that can only adjust the attitude of the pontoon are in a harsh environment where multiple sea conditions change at the same time. The all-round adjustment mechanism of the present invention has obvious advantages and can effectively make up for the shortcomings of a single adjustment method. The present invention has a simple structure through the cooperation between the propeller and the fairing, which is easy to construct and apply; at the same time, combined with intelligent means, it can adapt well to the complex wave loads at sea, can reduce the stress on the marine anchor chain, and improve the stability of the platform; 2. The data is collected in real time through sensors and quickly transmitted to the control center. The control center uses preset algorithms and dynamic models to conduct a comprehensive and integrated analysis and judgment of complex sea conditions, and then accurately calculates the draft depth and the adjustment parameters of the stabilizing fins, and converts them into control instructions to drive the corresponding mechanism actions; this intelligent control process realizes real-time and precise control of the state of the breakwater, effectively protects various marine facilities such as ports, coastal facilities and offshore operating platforms, greatly reduces the risk of damage to these facilities caused by wave invasion, and lays a solid and reliable guarantee for marine development and engineering construction, which is unmatched by other devices.

DETAILED DESCRIPTION

[0031] The specific technical scheme of the present invention is further described in detail below with reference to specific examples.

[0032] As shown in the figure, the adaptive floating breakwater suitable for complex sea conditions described in the present invention includes a wave system 1, a buoy 2, an anchoring system 3, a control center 7, a draft depth adjustment mechanism 8 and a floating body attitude adjustment mechanism 9;

[0033] A wind direction sensor 5, a wave height sensor 6 and a control center 7 are fixedly installed on the top of the wave system 1, and a flow velocity sensor 4 is fixedly installed on the side of the wave system 1;

[0034] In marine development and marine engineering construction, breakwaters are important structures to ensure the safety of ports, coastal facilities and offshore operating platforms. The draft depth adjustment mechanism 8 and the floating body attitude adjustment mechanism 9 can automatically adjust their own draft depth and floating body attitude, always maintain the best wave-breaking effect, and effectively protect marine facilities from waves.

[0035] Furthermore, anchoring systems 3 are installed at the four corners of the wave system 1. The anchoring system 3 uses high-strength corrosion-resistant cables. One end of the cable is connected to anchoring points evenly distributed around the bottom of the wave system 1, and the other end is fixed to a preset anchor on the seabed.

[0036] Furthermore, the wave system 1 is composed of a plurality of wave floating piles 101, and the wave system 1 adopts a modular design;

[0037] A group of floating bladders 2 are fixedly installed around the wave system 1 , each group of floating bladders 2 is composed of a plurality of floating bladders, and the bottom of each group of floating bladders 2 is lower than the bottom of the wave system 1 .

[0038] Furthermore, the draft depth adjustment mechanism 8 includes a base 801 fixedly installed at the center of the bottom of the wave system 1, a water pump 802 is fixedly installed inside the base 801, and a main delivery pipe 803 is fixedly installed at the water outlet of the water pump 802;

[0039] Water pressure sensors 804 are fixedly installed at the four corners of the bottom of the wave system 1;

[0040] A ballast water chamber is provided inside each of the wave floating piles 101, a shunt pipe is fixedly connected between the main delivery pipe 803 and each ballast water chamber, and a valve is fixedly installed on the outer surface of each shunt pipe;

[0041] When the water pressure sensor 804 detects changes in sea conditions, it transmits the data to the control center 7, which, based on the preset algorithm and program, conducts comprehensive analysis in combination with various sensor data to determine the current sea conditions and calculate the draft depth that needs to be adjusted;

[0042] The draft depth is adjusted by the command issued by the control center 7 to control the opening and closing of the valve and the operation of the water pump 802. When the draft depth needs to be deepened, the control center 7 opens the valve connected to the ballast water tank and starts the water pump 802 to fill the ballast water tank with water. As the water is injected, the weight of the breakwater increases and the draft depth gradually deepens. During the water injection process, the data of the water pressure sensor 804 is continuously monitored. When the target draft depth is reached, the control center 7 closes the water pump 802 and the corresponding valve; when the draft depth needs to be reduced, the control center 7 controls the water pump 802 to discharge the water in the ballast water tank, so that the draft of the breakwater becomes shallower, reducing energy consumption and hydrodynamic resistance.

[0043] The water pressure sensor 804 senses the changes in seawater pressure in real time. According to the liquid pressure formula: P=ρgh, where P is the pressure intensity, ρ is the seawater density, g is the gravitational acceleration, and h is the water depth, the information on wave height and water flow speed can be indirectly calculated by measuring the pressure changes.

[0044] Further, the floating body attitude adjustment mechanism 9 includes a connection frame 901 fixedly installed at the bottom of the wave system 1, a hydraulic cylinder 902 is fixedly installed on the inner top wall of the connection frame 901, a flange 903 is fixedly installed on the driving end of the hydraulic cylinder 902, a stabilizing fin 904 is also connected to the driving end of the hydraulic cylinder 902, an installation cavity 905 is opened inside the connection frame 901, an oil storage tank 906 is fixedly installed inside the installation cavity 905, a hydraulic pump 907 is also fixedly installed inside the installation cavity 905, a hydraulic pipe 908 is fixedly installed at one end of the hydraulic pump 907, a hydraulic valve 909 is fixedly installed on the outer surface of the hydraulic pipe 908, and an oil return pipe 910 is connected between the hydraulic cylinder 902 and the oil storage tank 906;

[0045] A plurality of adjustable stabilizing fins 904 are installed at the bottom of the breakwater. The stabilizing fins 904 are generally made of high-strength, corrosion-resistant metal materials, such as aluminum alloy. The shape and size of the stabilizing fins 904 are optimized according to the design requirements of the breakwater and the expected sea conditions.

[0046] When the direction of the water flow changes or the waves generate large rolling and pitching forces, the sensors in the sea condition sensing system, such as the wind direction sensor 5, the wave height sensor 6 and the flow velocity sensor 4, transmit the collected data to the control center 7. The control center 7 calculates the required adjustment parameters of the stabilizing fin 904, including the angle and extension length of the stabilizing fin 904, based on the data, combined with the dynamic model of the breakwater and the preset control algorithm;

[0047] During adjustment, the control center 7 converts the calculated adjustment parameters into control instructions and sends them to the hydraulic system. The hydraulic valve 909 in the hydraulic system controls the flow direction and flow rate of the hydraulic oil according to the instructions, and drives the hydraulic cylinder 902 to move. For example, when the control center 7 calculates that the left stabilizing fin 904 needs to extend downward by a certain angle to offset the rightward rolling moment, the hydraulic system controls the piston rod of the corresponding hydraulic cylinder 902 to extend, and drives the stabilizing fin 904 to rotate downward to a specified angle.

[0048] After the stabilizing fin 904 is actuated, the direction of the force exerted by the water flow on the breakwater is changed, thereby offsetting part of the roll and pitch moments and changing the floating posture of the breakwater; in this process, the wind direction sensor 5, the wave height sensor 6 and the flow rate sensor 4 continuously monitor the changes in the posture of the breakwater and feed the data back to the control center 7. The control center 7 adjusts the adjustment parameters of the stabilizing fin 904 in real time according to the feedback data to ensure that the breakwater always maintains a stable floating posture and improves the wave-breaking effect.

[0049] Furthermore, the control center 7 has a built-in complex sea condition adaptive algorithm model; the model uses various sea conditions such as wave height, wind direction, water flow speed and water pressure as input variables.

[0050] For the wave height, based on the echo time data obtained by the wave height sensor, a radar wave height sensor is selected according to the wave height sensor 6. The calculation method is: the propagation speed of radar waves in the air is approximately equal to the speed of light c0 = 3×10 8 m / s, the time interval from radar wave transmission to reception is Δt1 (unit: second). Since radar sensors are generally installed at a certain height H (unit: meter) above the sea surface, the calculation formula for wave height h1 is: The sensor records Δt1 and obtains its own installation height information to calculate the wave height.

[0051] For wind direction, the wind direction sensor 5 uses a cup wind direction sensor, and its calculation method is: wind speed Where r is the rotation radius of the wind cup (unit: meter), which can be determined by measuring the distance from the center of the wind cup to the edge of the cup mouth; n is the rotation speed of the wind cup per minute (unit: revolutions / minute), which is obtained by the rotation speed measurement device inside the sensor; the wind direction is determined by the angle between the wind vane and the compass reference direction, assuming that the angle is θ, with the north direction as 0° and the clockwise direction as positive. The wind direction angle can be obtained through the corresponding relationship between the wind vane and the angle measurement device inside the sensor, such as θ = 30°, which means that the wind direction is 30° north by east;

[0052] As for the water flow velocity, the flow velocity sensor 4 uses an electromagnetic flow velocity sensor, and its calculation method is as follows: According to the law of electromagnetic induction, the relationship between the induced electromotive force E and the water flow velocity v1 is E=BLv1, where B is the magnetic field strength (unit: Tesla), which is generated by the excitation device inside the sensor and can be obtained by measurement; L is the effective length of the water flow cutting the magnetic lines of force (unit: meter), which is determined by the structural size of the sensor; E is the induced electromotive force (unit: volt), which is obtained by the voltage measurement circuit inside the sensor, then the water flow velocity

[0053] On this basis, an algorithm combining multiple linear regression and neural network is used to establish a comprehensive assessment model of sea conditions. Parameters such as wave height, wind direction, water flow speed and water pressure are used as independent variables of multiple linear regression, and the complexity assessment results corresponding to historical sea condition data are used as dependent variables to construct a multiple linear regression equation y=β0+β1x1+β2x2+…+β n x n +∈(where y is the evaluation value of sea state complexity, β i is the regression coefficient, x i are the sea condition parameters, ∈ is the error term), and at the same time, these parameters are used as input layer neurons, and nonlinear transformation is performed through multiple hidden layers, and finally the sea condition complexity index is output; a large amount of historical sea condition data is used to train the model, adjust the regression coefficient and the weight and threshold of the neural network, and improve the accuracy of the model.

[0054] The control center 7 determines the current sea conditions and calculates the draft depth that needs to be adjusted based on the preset algorithms and programs and comprehensive analysis of various sensor data;

[0055] The control center 7 uses the above-mentioned comprehensive sea condition assessment model to input the data collected by the sensors in real time into the model:

[0056] For example, at a certain moment, the radar wave height sensor 6 measures t = 0.001s, the sensor installation height H0 = 5m, and the calculated wave height h = 3×10 8×0.001 / 2-5=145m; the cup wind direction sensor 5 collects the original wind speed data of 15m / s. After Kalman filter processing, the wind direction is determined to be 45° north-east; the electromagnetic flow velocity sensor measures the induced electromotive force E=0.05V, the magnetic field strength B=0.01T, the effective length of the water flow cutting the magnetic line of force L=2m, and the water flow velocity v=2.5m / s is calculated; the water pressure sensor 804 measures the pressure P=1.05×10 5 Pa, according to the liquid pressure formula, the corresponding water depth is h=10.7m.

[0057] The model outputs a complexity score of the current sea conditions based on key parameters such as the wave height index, wind direction deviation angle, water flow velocity change rate, and water pressure fluctuation range, through calculations by a multi-layer neural network; assuming that the sea condition complexity score output by the model reaches 80 points (out of a full score of 100 points), which exceeds the set threshold of 60 points, indicating that the sea conditions are severe; the model further calculates the draft depth value that needs to be adjusted to maintain the stability of the breakwater based on the pre-trained decision tree model, combined with the dynamic equation F=ma (where F is the external force, m is the mass of the breakwater, and a is the acceleration), as well as the structural parameters and mechanical properties of the breakwater; assuming that the calculation shows that the draft depth needs to be increased by 0.5m.

[0058] At the same time, for the adjustment of the floating body attitude, the model uses the optimal control algorithm, such as the linear quadratic optimal control algorithm, based on the complexity score of the sea conditions and the real-time roll and pitch angle data of the breakwater (for example, the current roll angle is 5° and the pitch angle is 3°), to minimize the roll and pitch moments as the objective function, and determines the angle and extension length of the stabilizing fin 904 that need to be adjusted; assuming that the calculation shows that the stabilizing fin 904 needs to be extended downward by 20° and the extension length increased by 0.3m, in order to achieve effective offset of the roll and pitch moments, thereby ensuring that the breakwater always maintains a stable floating body attitude.

[0059] In summary, the adaptive floating breakwater suitable for complex sea conditions can accurately obtain key sea condition information such as wave height, wind direction and water flow speed by integrating multiple sensors, such as radar wave height sensor, wind cup wind direction sensor and electromagnetic flow velocity sensor, and make accurate calculations with the help of preset formulas. The draft depth adjustment mechanism 8 and the floating body attitude adjustment mechanism 9 can quickly and accurately adjust the draft and floating body attitude of the breakwater according to the sensor data and the instructions of the control center 7; for example, when the wave height increases, the draft depth adjustment mechanism 8 can deepen the draft in time to enhance stability and wave-breaking ability; when the water flow direction or wave force changes and causes the breakwater to roll and pitch, the floating body attitude adjustment mechanism 9 adjusts the angle and extension length of the stabilizing fin 904 to effectively offset the torque and maintain a stable attitude, thereby always maintaining an efficient wave-breaking effect under complex sea conditions.

[0060] In addition, the adaptive floating breakwater has built an intelligent sea condition perception and control system. The sensors collect data in real time and transmit it to the control center 7. The control center 7 uses preset algorithms and dynamic models to comprehensively analyze and judge the sea conditions, and then accurately calculates the draft depth and the adjustment parameters of the stabilizing fins 904, and converts them into control instructions to drive the corresponding mechanism actions. This intelligent control process realizes real-time and accurate control of the breakwater state, effectively protects marine facilities such as ports, coastal facilities and offshore operating platforms, greatly reduces the risk of damage to these facilities caused by wave invasion, and provides reliable protection for marine development and engineering construction.
