[0002] The pipeline system of negative pressure sinking of offshore cylinder foundation is widely used as a sinking technology for offshore wind turbines. It has several main functions in the installation process of cylinder foundation: exhaust sinking, drainage sinking, sinking system, negative pressure reinforcement. During the sinking process of cylinder foundation, it is often necessary to control the opening and closing of water pumps and valves, and monitor the flow rate, inclination angle, and pressure of each bin in real time to ensure that the foundation sinking level meets the design requirements.

[0003] During the construction process, the barrel foundation initially sinks to a specific depth of the seabed by its own gravity, constructing a confined space in the barrel. Then, the water and air in the barrel are continuously pumped out to form a negative pressure environment in the barrel. Then, according to the soil conditions of the construction seabed, the pressure difference value inside and outside the foundation is continuously adjusted to enable the barrel foundation to be successfully sunk and installed at a predetermined position. However, most of them currently use a large-flow pumping pipeline system, for example, a single set of pipelines and valves are controlled, and each compartment can only be controlled by one button, and multiple valves cannot cross-control the same compartment. Therefore, a large-flow pumping pipeline system is needed that can use the internal and external pressure difference to control the horizontality of the barrel foundation, and continuously adjust the negative pressure inside the barrel foundation during sinking, correct the sinking direction, and cross-control the same compartment. Summary of the invention

[0008] In the preferred solution, a corresponding inclination sensor is used to determine whether the inclination angle of the barrel foundation is greater than a set first inclination threshold value according to the inclination angle data, and a PLC is connected to the corresponding inclination sensor signal.

DETAILED DESCRIPTION

[0018] An embodiment of the present invention provides a multi-bin barrel-type foundation piping system for cross-controlling the same compartment. The system can cross-control the opening and closing degree of the branch where the pipelines, water pumps, and valves are located according to the relationship between the parameter values ​​of the physical parameters set by seawater and / or gas in the pipelines and the preset range of the parameter values ​​of the set physical parameters, so as to achieve the purpose of leveling the inclination angle of the barrel-type foundation.

[0019] In order to better understand the purpose, structure and function of the present invention, the following reference is made to the attached Figure 1-2 The present invention is described in detail with reference to embodiments.

[0020] Example 1 like Figure 1 , 2 As shown, the interactive control system 100 is electrically connected to the underwater hydraulic control system 200, and the underwater hydraulic control system 200 can achieve remote communication and control through the instructions input by the interactive control system 100; The interactive control system 100 includes a human-machine interface HMI 101 and a programmable logic controller PLC 102 electrically connected to the HMI 101. The PLC 102 uses a display screen to write working parameters and / or input operation commands to achieve human-machine information interaction. Among them, the human-machine interface (HMI), also known as a touch screen monitor, is an intelligent operation control and display device. When the screen is touched, the resistance and voltage on the resistor network will change and the touch position can be calculated by the software; it is also called the "human-machine interface", and its main function is to help people establish contact and exchange information between computers. The interface of input / output devices includes keyboards, monitors, printers, mice, etc.

[0021] Programmable Logic Controller (PLC) is a digital operation controller with a microprocessor for automated control. It can load control instructions into memory at any time for storage and execution. PLC consists of functional units such as CPU, instruction and data memory, input / output interface, power supply, digital-to-analog conversion, etc.

[0022] The communication method between HMI and PLC is one or more of serial communication, Ethernet / IP, fieldbus, OPCUA open platform communication and / or DNP3 / DNPv3, and further preferably serial communication, for example, RS-232, RS-485 or USB, which was the most commonly used HMI-PLC connection method in the early days, and data was exchanged through cables.

[0023] Further preferred is a field bus, for example, PROFINET, MODBUSTCP, CANBus, etc., which provides high-speed and reliable data transmission and supports multi-device connection.

[0024] The underwater hydraulic control system 200 is provided with a hydraulic power pump station 201 and a pipeline control system 202 which are sequentially connected by pipelines to form an open cycle and are electrically connected to each other; In addition, an underwater electronic cabin control 207 is provided for receiving instructions from the HMI 101 and controlling the start and stop of the hydraulic power pump station 201, so as to control and / or monitor the sinking process of the barrel foundation according to preset parameters and algorithms.

[0025] Figure 2 In the embodiment, the pipeline control system 202 includes: Buttons 204 are interfaces for operators to interact with the system. By pressing different buttons, operators can send instructions to control the pipeline 206 of the pipeline control system 202.

[0026] Among them, Figure 2 As shown in the figure, each button can control the pipelines of two compartments to pump water to improve the pumping efficiency. The pipeline part is improved from the original single set of 7 valves to double sets of 14 valves, and equipped with 2 sets of pipeline systems. The 2 sets of system structures are independent of each other, but they are still cross-controlled by the original 7 buttons.

[0027] Taking 7 cabins as an example, button No. 1 can control cabin 1 and cabin 2; button No. 2 can control cabin 2 and cabin 3; button No. 3 can control cabin 3 and cabin 4; button No. 4 can control cabin 4 and cabin 5; button No. 5 can control cabin 5 and cabin 6; button No. 6 can control cabin 6 and cabin 1; and so on, forming cross control. Since the middle cabin 7 does not participate in leveling, it can still be controlled by button No. 7.

[0028] The cabin 205 is connected to two sets of pipelines 206 cross-controlled with the same cabin 205; At least two groups of underwater pumps 203 are provided with power source by the hydraulic power pump station 201. When the valve is out of control and the inclination of the barrel foundation is greater than the set inclination threshold, the corresponding button 204 will be triggered. Through the cross control of the underwater pump group 203, the two sets of pipelines 206 will stop and / or reduce the discharge pressure, and the horizontality of the barrel foundation will be controlled by utilizing the internal and external pressure difference, and it will be restored to a balanced state.

[0029] Specifically, when the barrel foundation tilts, the system will detect the change in inclination. If the inclination exceeds the set threshold, the system will automatically take measures to correct the tilt. At this time, the operator can control the start of the underwater pump group 203 by pressing the corresponding button 204, and adjust the discharge pressure of the two sets of pipelines 206 according to the instruction of the button 204. By reducing or stopping the discharge pressure of one set of pipelines 206, the discharge pressure of the other set of pipelines 206 can be increased, thereby generating a reverse force to correct the inclination of the barrel foundation. In this process, the internal and external pressure difference plays a key role. Due to the different pressures inside and outside the barrel foundation, the size and direction of the internal and external pressure difference can be changed by adjusting the discharge pressure of the pipeline 206. When the internal and external pressure difference reaches a certain level, it will generate a force large enough to push the barrel foundation back to a horizontal position.

[0030] In the preferred embodiment, Figure 2 , 3 As shown in FIG. 4 , the underwater pump group 203 includes a pressure discharge port, a plurality of submersible pumps 2033, a plurality of hydraulic valves 2034 and an electromagnetic flowmeter 2035 which are sequentially connected through a pipeline 206 to form an open circulation loop; The button 204 is respectively connected to the plurality of submersible pumps 2033, the plurality of hydraulic valves 2034, the electromagnetic flowmeter 2035 and the induction component signals; Further preferably, the submersible pump 2033 has a power of 200 kW, a pumping flow rate of 750 m³ / h, a maximum negative pressure of -0.06 MPa at the water inlet of the submersible pump, and a maximum pressure of 0.8 MPa at the water outlet. All pipelines 206 are made of seamless steel pipes, and the pipelines 206 are connected by elbows. The diameter of the pipeline 206 is determined according to the specific required flow rate.

[0031] In the specific operation process, when the inclination of the barrel foundation is greater than the set first inclination threshold, the button 204 will receive a signal from the sensing component and accordingly control the submersible pump 2033 and the hydraulic valve 2034 to open. In this way, the pressure of the pressure relief port can be increased, thereby adjusting the inclination of the barrel foundation.

[0032] On the contrary, when the inclination of the barrel foundation is less than the set second inclination threshold, the button 204 will receive the signal from the sensing component again and control the submersible pump 2033 and the hydraulic valve 2034 to shut down respectively. This can reduce the pressure of the pressure relief port and keep the barrel foundation in a stable horizontal state.

[0033] In addition, the electromagnetic flowmeter 2035 is used to monitor the liquid flow in the pipeline 206 to ensure the normal operation and precise control of the system.

[0034] In the preferred embodiment, the underwater pump group 203 further includes a plurality of sensing components, which are arranged outside the pipeline 206 and are used to monitor the inclination angle of the barrel foundation to obtain inclination angle data; Preferably, when the sensing component is composed of a pressure sensor 2037 and an inclination sensor 2038, and the inclination angle data is set to be pressure and inclination, the pipeline control system 202 provided by the embodiment of the present invention is as follows: Figure 3 , 4 As shown, the pressure sensor 2037 and the inclination sensor 2038 are located in the pipeline 206.

[0035] The pressure sensor 2037 is used to measure the pressure on the barrel foundation, while the inclination sensor 2038 is used to measure the inclination angle of the barrel foundation.

[0036] It is used to increase the opening of the hydraulic valve 2034 when the inclination angle of the barrel foundation measured by the pressure sensor 2037 and the inclination sensor 2038 during the sinking process is less than the lower limit of the inclination angle of the barrel foundation within the preset range; and to reduce the opening of the hydraulic valve 2034 when the inclination angle of the barrel foundation is greater than the upper limit of the inclination angle of the barrel foundation within the preset range during the sinking process; and to keep the opening of the hydraulic valve 2034 unchanged when the inclination angle of the barrel foundation is within the preset range.

[0037] When the barrel foundation tilts, the pressure sensor 2037 will detect the change in pressure, and the inclination sensor 2038 will detect the change in the inclination angle. The detection data will be transmitted to the underwater electronic cabin control 207. Then PLC102 obtains this type of data and adjusts the working state of the underwater pump group 203 based on this data, thereby restoring the barrel foundation to a horizontal state.

[0038] Optionally, in combination with Example 1, when the inclination of the barrel foundation is greater than a set first inclination threshold, the embodiment of the present invention provides the following Figure 1 , 2 As shown, the first tilt threshold is described in detail.

[0039] By analyzing the inclination angle data, it is determined whether the inclination angle of the barrel foundation is greater than the set first inclination threshold value of the corresponding inclination sensor 2038, and the PLC102 connected to the signal of the inclination sensor 2038. When the inclination angle of the barrel foundation exceeds the set first inclination threshold value, the button 204 will control the opening of the submersible pump 2032 and the hydraulic valve 2033 through the PLC102.

[0040] Among them, the value range of the first tilt threshold is set between 0.2° and 0.25°, ensuring that when the inclination angle of the barrel foundation reaches a certain degree, corresponding measures can be taken in time to ensure the safe and stable operation of the system.

[0041] The inclination sensor 2038 will monitor the inclination angle of the barrel foundation in real time and transmit the data to PLC102. PLC102 will process and analyze the data to determine whether the inclination angle of the barrel foundation exceeds the set first inclination threshold.

[0042] Once the inclination angle of the barrel foundation exceeds the first inclination threshold, the emergency braking system will be triggered. Through the control of PLC102, the submersible pump 2032 and the hydraulic valve 2033 can be stopped or the opening and closing degree can be reduced to reduce the inclination angle. The hydraulic valve 2033 is used to control the hydraulic system to adjust the posture of the barrel foundation. Further, the specific parameters and settings will be adjusted and optimized according to the actual situation to adapt to different application scenarios and needs.

[0043] Optionally, in combination with Example 1, when the inclination of the barrel foundation is less than the set second inclination threshold, the embodiment of the present invention provides the following Figure 1 , 2 As shown, the second tilt threshold is described in detail.

[0044] By analyzing the inclination angle data, the corresponding inclination sensor 2038 will determine whether the inclination angle of the barrel foundation is less than the set second inclination threshold. The inclination sensor 2038 is connected to the PLC102 signal. When the inclination angle of the barrel foundation is less than the set second inclination threshold, the button 204 will control the submersible pump 2032 and the hydraulic valve 2033 to close through the PLC102.

[0045] The second tilt threshold value ranges from 0° to 0.1°. The setting of the range is carefully considered to ensure that when the inclination of the barrel foundation reaches a certain degree, appropriate measures can be taken in time to ensure the safe and stable operation of the system.

[0046] The inclination sensor 2038 monitors the inclination angle of the barrel foundation in real time and transmits the data to the PLC 102. The PLC 102 processes and analyzes the data to determine whether the inclination angle of the barrel foundation is less than the set second inclination threshold.

[0047] Once the inclination angle of the barrel foundation is less than the second inclination threshold, the emergency braking system will be triggered. Under the control of PLC102, the submersible pump 2032 and the hydraulic valve 2033 will be closed. The function of the submersible pump 2032 is to pump out water to reduce the weight of the barrel foundation and thus reduce its inclination angle. The hydraulic valve 2033 is used to control the hydraulic system to adjust the posture of the barrel foundation. Furthermore, the specific parameters and settings may be adjusted and optimized according to the actual situation to adapt to different application scenarios and needs.

[0048] Further explanation is given in combination with the above-mentioned embodiments 1 and 2. Figure 3 , 4 The structure shown.

[0049] The pipeline 206 exhausts and / or drains the corresponding chamber 205 by conveying seawater, so as to form a negative pressure inside the barrel foundation and cause it to sink. Negative pressure refers to a pressure state lower than atmospheric pressure. When the hydraulic valve 2034 is opened, the external atmospheric pressure is higher than the pressure inside the barrel foundation, forming a negative pressure difference.

[0050] A hydraulic valve 2034 is provided at the front end of the inlet of the pipeline 206. When seawater and / or gas flows through the pipeline 206, they first pass through the pressure sensor 2037, then pass through the hydraulic valve 2034, and finally are connected to the pressure outlet of the pipeline 206. The pressure outlet can be the water outlet 2031 and / or the gas outlet 2032.

[0051] In addition, at least two hydraulic valves 2034 are provided at the rear end of the water outlet 2031. When seawater flows through the pipeline 206, it first flows through the hydraulic valve 2034, then flows through the submersible pump 2033, and finally is discharged from the water outlet 2031.

[0052] At the same time, at least one hydraulic valve 2034 is located at the rear end of the exhaust port 2032 , and the gas will be discharged from the exhaust port 2032 after flowing through the pipeline 206 .

[0053] By controlling the underwater electronic cabin control 207, the sinking process of the barrel foundation can be monitored and controlled, and data from various sensors, such as pressure, depth, inclination, etc., can be received, and the sinking process can be controlled according to preset parameters and algorithms to adjust the opening and closing degree of the exhaust valve and the drain valve, control the operation of the submersible pump 2033, and monitor the position and posture of the foundation to ensure the accuracy and safety of the sinking process.

[0054] The pressure sensor 2037 can monitor the pressure changes in the pipeline 206 in real time, providing important data support for the control of the system. The hydraulic valve 2034 can control the flow of seawater and gas as needed to ensure the normal operation of the system. The submersible pump 2033 is used to provide additional drainage power to meet the needs of the system.

[0055] The technical solution of the present invention is described in detail in combination with the above-mentioned multiple embodiments. Figure 5 In the structure shown, the number of the cabins 205 is at least seven, and they are spaced apart from each other. These spaced apart cabins 205 are arranged in a ring shape with the rotation axis as the center. Each cabin 205 is used to connect at least two pipelines 206. If a hanging line in a cabin 205 fails or needs maintenance, after adjustment, other cabins 205 can still continue to work to ensure the normal operation of the system. At least one submersible pump is connected through the port of the flow valve to achieve independent control and adjustment between different cabins 205. Secondly, the cabins 205 arranged in a ring can provide uniform distribution and support, which helps to improve the stability and balance of the entire structure. The vibration and noise of the system can be reduced.

[0056] Optionally, after the opening of the hydraulic valve 2034 is reduced, through a series of monitoring and judgment steps, it can be determined that the opening of the hydraulic valve 2034 is less than the lower limit of the allowable opening. At this time, the electromagnetic flowmeter 2035 will send a key message to the underwater electronic cabin control 207, that is, to reduce the discharge of seawater and / or gas per unit time.

[0057] Optionally, after the opening of the hydraulic valve 2034 increases, corresponding monitoring and judgment will also be performed. Once it is determined that the opening of the hydraulic valve 2034 is greater than the lower limit of the allowable opening, the electromagnetic flowmeter 2035 will send another important information to the underwater electronic cabin control 207, that is, increase the discharge of seawater and / or gas per unit time.

[0058] As a key monitoring device, the electromagnetic flowmeter 2035 can accurately measure the flow rate per unit time and transmit the relevant information to the underwater electronic cabin control 207. After receiving the information from the electromagnetic flowmeter 2035, the underwater electronic cabin control 207 will take corresponding discharge measures according to the specific situation, for example, adjust the operating parameters of other related equipment to ensure the stability and safety of the system.
