Its rational development and utilization are of great significance to alleviating the energy crisis and improving environmental pollution. Offshore wind turbines are widely used, but at the same time they face the risk of pile foundation safety caused by the erosion of the seabed by long-term sea currents.

[0016] The support arm is arranged on the base and driven by a vertical motor, and the vertical motor is connected to the energy storage device through a wire; a solar panel is arranged on the top of the support arm.

[0019] Ultrasonic wave meters are used to monitor instantaneous wave data on the water surface;

[0020] The data analysis processor acquires the data and transmits it to the wireless signal transmitter.

[0021] In the offshore wind power scour warning device based on pore water pressure measurement described in the present invention, the ultrasonic wave measuring instrument is located directly above the pore water pressure measuring point;

[0022] The pore water pressure measuring point is set at a certain distance from top to bottom along the seabed elevation around the wind turbine tower;

[0023] Ten pore water stress sensors are evenly distributed at 1.5 times the maximum pile diameter under the seabed of the wind turbine tower.

[0024] The early warning method of the offshore wind power scour early warning device based on pore water pressure measurement described in the present invention is as follows:

[0025] Step 1: Arrange pore water pressure measuring points at the bottom of the wind turbine tower, set up a supporting structure on the wind turbine tower, and install an energy supply module and a solar module on the supporting structure; build an energy collection device that uses the solar module to supply energy to the energy supply module, and supply energy to the pore water pressure measuring points and the ultrasonic wave meter monitoring device through the energy supply module to maintain real-time monitoring of the pile foundation;

[0031] The actual measured value of water pressure is that the maximum value of the dynamic water pressure difference within one wave cycle is between 97% and 103%. When the theoretical maximum value of the dynamic pressure difference within one wave cycle is reached, the surface is no longer covered by seabed soil and erosion has occurred.

[0032] In the early warning method of the offshore wind power scour early warning device based on pore water pressure measurement of the present invention, in step 2, the ultrasonic wave meter obtains the average sea surface height in the past 1 minute, and the distance z from the sea surface to the measuring point can be calculated according to the height of the ultrasonic wave meter relative to the pore water pressure measuring point, and the expression is as follows:

[0033]

[0034] If the seabed at the measuring point has just been eroded, then z = -h at this point, and the maximum value of the theoretical dynamic pressure difference at each point is:

[0035]

[0036] Where p is the dynamic pressure, z is the distance from the measuring point to the sea surface, A is the wave height, kx-σt is the phase function, and k is the wave number It represents the number of waves on a length of 2π, L is the wavelength, which can be obtained from the wave meter, σ is the circular frequency, T is the wave period, ρ is the local seawater density, and g is the local gravity acceleration. If the difference between the measured values ​​is not within the range of 97% to 103% of the theoretical value, it is considered that the seabed has not been eroded to the measuring point.

[0056] The ultrasonic wave meter 19 is used to monitor instantaneous wave data on the water surface; the data analysis processor acquires the data and transmits it to the wireless signal transmitter.

[0057] A series of pore water pressure sensor measuring points are set longitudinally within the range of 1.5 times the pile diameter depth of the seabed around the pile foundation. The support structure can carry the energy supply module and adjust the angle of the solar panel. The solar panel has a rectangular geometry and is fixed to the vertical rotation support arm by screws. The support plane is placed horizontally, perpendicular to the straight line where the pile is located. There are four horizontal rollers, which are respectively installed on the slots of the horizontal turntable, and the horizontal roller drive motor provides the rotation power. The horizontal roller drive motor uses a wire to connect the circuit with the energy storage device, and the energy is provided by the energy storage device. The solar panel is made of high-efficiency monocrystalline silicon material, with an area of ​​2 square meters. It is installed on the upper part of the wind turbine tower and can track the position of the sun through preset rotation to maximize energy collection.

[0058] The pore water pressure measuring point 20 is connected to a solar panel 17 installed on the pile body above the water surface by a conductor, and the solar panel 17 provides energy.

[0059] The horizontal rotating tray has a card slot that matches the size of the horizontal roller, and the upper part is equipped with an energy storage device, a solar panel, a vertical rotating motor, a vertical rotating support arm, a data information analysis processor and a wireless signal transmitter.

[0060] The energy storage device is connected to the solar panel through a wire.

The energy storage device uses a lithium-ion battery pack with a total capacity of 10 kWh. The battery status is monitored through an intelligent battery management system (BMS) to prevent overcharging and over-discharging and extend the battery life.

[0061] The real-time monitoring module is divided into a pore water pressure sensor and an ultrasonic wave meter. The pore water pressure sensor is installed on the surface of the wind turbine pile, including a series of pore water pressure sensors, which are arranged along the vertical direction of the seabed around the wind turbine pile foundation to monitor the changes in pore water pressure at different depths. The sensor is connected to the data information analysis processor through a wire to transmit monitoring data in real time. The ultrasonic wave meter is tied to the side of the pile at the same horizontal position as the pore water stress sensor.

[0062] The real-time monitoring module is installed on the fan corresponding to the monitoring point, and a wireless serial port pore water pressure monitoring module, a data analysis processor, an ultrasonic wave meter, a data transmission line and a wireless signal transmitter are installed in it. The data information analysis processor analyzes the data transmitted by the data transmission line from the pore water pressure monitoring module and the data obtained from the ultrasonic wave meter, and sends the analysis results to the remote monitoring module through the wireless signal transmitter.

[0063] The data analysis processor is the core of this system, which includes a wireless signal receiving and transmitting base station and a data analysis processor. The wireless signal receiving and transmitting base station is installed on the horizontal tray, in the same position as the data analysis processor, and is responsible for receiving and transmitting to the remote monitoring module. The analysis processor is installed next to the energy storage device, receiving and processing data from the pore water stress sensor and ultrasonic wave meter, analyzing the risk of seabed scour, and automatically sending warning information when an abnormality is detected.

[0064] Arrangement of pore water pressure measurement points: Starting from the seabed elevation around the pile foundation, a measurement point is set at a certain distance from top to bottom. The deepest point is 1.5 times the maximum pile diameter below the seabed. 10 pore water stress sensors are evenly arranged.

[0065] The pore water pressure is detected by the pore water pressure measuring point and the data is transmitted to the data information analysis processor through the data transmission line.

[0066] The data information analysis processor receives the pore water pressure data sent by the pore water pressure sensor, analyzes whether there is a risk of scour based on the data, and sends the safety information to the remote monitoring module.

[0067] Ultrasonic wave measuring instruments are arranged directly above a series of measuring points in the same vertical direction. The wave measuring instruments can measure the instantaneous wave parameters (theoretical parameters) at the same horizontal position of these measuring points, including wave height and period.

[0068] The maximum value of the theoretical dynamic pressure difference of each pore water pressure measuring point within a wave cycle without seabed coverage can be calculated using wave pressure theory;

[0069] The early warning method of the offshore wind power scour early warning device based on pore water pressure measurement, the early warning steps are as follows:

[0070] Step 1: Fix the support module: Install the support module at the bottom of the wind turbine tower, install the rotating tray horizontally, and install the horizontal roller.

[0071] Solar panel installation: Install solar panels on the supporting modules and ensure that they are positioned to automatically track the sun; connect the solar panels to the energy storage device through wires and monitor the battery status through the BMS system.

[0072] Step 2, sensor arrangement: pore water pressure sensors are arranged in the vertical direction in the seabed around the wind turbine pile foundation, and connected to the energy storage device through a wire, and connected to the data analysis processor through a data transmission line. The ultrasonic wave meter is connected to the energy storage device through a wire, and connected to the data analysis processor through a data transmission line;

[0073] Data analysis processor installation: It is installed on a horizontal tray so that it can receive signals from the pore water stress sensor and ultrasonic wave meter and send the results of data analysis to the remote monitoring module.

[0074] Data analysis processor setting: Set up the data analysis processor in the control room, configure the corresponding analysis algorithm, and set the warning threshold.

[0075] Step 3: After all hardware installation is completed, perform system testing, including energy collection testing of solar panels, data transmission testing of sensors, and response testing of the early warning system.

[0076] The BMS system monitors the charging and discharging status of the battery to ensure effective energy management. The sensor monitors the pore water pressure in real time, records the real-time data, and uploads it once every second. The wave meter simultaneously records the real-time wave data and uploads it once every second. The data analysis processor receives the data and analyzes the scour risk based on the built-in algorithm. Once the analysis results show that the scour risk exceeds the preset threshold, the system automatically sends an early warning message.

[0077] The theoretical value of wave dynamic pressure is obtained by using the wave meter to obtain the average sea surface height in the past minute. The distance z from the sea surface to the measuring point can be calculated based on the height of the wave meter relative to the measuring point:

[0078]

[0079] Now assume that the seabed at the measuring point has just been eroded, then z = -h at this point, and the maximum value of the theoretical dynamic pressure difference at each point is:

[0080]

[0081] Where p is the dynamic pressure, z is the distance from the measuring point to the sea surface, and A is the wave height; Obtained from a wave meter.

[0082] Therefore, whenever the difference between the measured values ​​is not within the range of 97% to 103% of the theoretical value, it is considered that the seabed has not been eroded to the measuring point.

[0083] Daily maintenance: Regularly check the cleanliness of the solar panels and the battery status of the energy storage device to ensure stable operation of the system. Clean the solar panels every quarter and conduct an in-depth inspection of the energy storage device once a year.

[0084] The principle of the present invention is that the device uses a remote monitoring module that can receive security information from a data analysis processor;

[0085] The vertical rotation motor is preset with time-varying deflection according to the location; the horizontal roller drive motor is preset with time-varying deflection according to the location; according to the deflection of the location, the solar panel can be turned toward the sun during the day, and in order to prevent the wires and data cables from getting tangled, it can be turned back to the initial position during the day on the same side at night. Adjust the angle of the solar panel according to the preset rotation to maximize energy collection.

[0086] For the upper layer of the uneroded measuring point, there is seabed soil covering the surface, and the absolute value of the dynamic water pressure caused by the waves is weakened, so the actual measured value will be different from the theoretical value. Taking into account the error of the measuring instrument, the maximum value of the dynamic water pressure difference within one wave cycle of the actual measured water pressure is between 97% and 103% of the theoretical maximum value of the dynamic pressure difference within one wave cycle, indicating that the surface is no longer covered by seabed soil and erosion has occurred.

[0087] The dynamic water pressure is calculated by the measured value and theoretical value. The average water level measured by the wave meter within 1 minute is regarded as the static water level. The measured water pressure minus the static water pressure is the measured dynamic water pressure.

[0088] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
