[0033] The core of this utility model is to provide a multi-point jet spray system for marine applications.

[0034] Please refer to Figure 1 .

[0035] The marine multi-point jetting system provided by this utility model includes a mounting frame 3, a sensor module, and a control module. Multiple jetting units 1 are arranged in an axial array inside the mounting frame 3. The sensor module is mounted on the mounting frame 3 and integrates various sensors for real-time monitoring of sea conditions and operational status. The control module is connected to the jetting units 1 and the sensor module to adjust the jetting parameters.

[0036] Specifically, multiple jetting units 1 are arranged in an axial array inside the mounting frame 3, which can expand the coverage of offshore operations. The sensor module is set on the mounting frame 3 and can integrate multiple sensors to monitor sea conditions and operational status in real time, and transmit the data to the control module. The control module is connected to the jetting units 1 and the sensor module, and can adjust the jetting parameters according to the data transmitted by the sensor module, thereby improving the efficiency, flexibility and safety of offshore operations. It can also optimize and dynamically adjust the jetting parameters to better adapt to different sea conditions and operational needs.

[0037] The aforementioned multi-point spraying system provides a stable support structure for the spraying unit 1 via the mounting frame 3, allowing it to be rationally positioned within the offshore operation area. The sensor module collects sea state and operational status data in real time and feeds this data back to the control module. Based on the received data, the control module uses algorithms to calculate the optimal spraying parameters and controls the spraying unit to perform the spraying operation. Through the coordinated work of its various components, the entire system significantly improves the efficiency, scope, and flexibility of offshore operations while ensuring operational safety, representing a significant improvement over traditional offshore spraying systems.

[0038] The marine multi-point jetting system provided by this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0039] In one specific implementation, reference is made to... Figure 1 and Figure 2 The mounting frame 3 includes an upper ring 31, a lower ring 32, and multiple vertical supports 33 connected between the upper ring 31 and the lower ring 32. Multiple spray units 1 are detachably mounted on the lower ring 32.

[0040] Specifically, the mounting frame 3 consists of an upper ring 31, a lower ring 32, and multiple vertical supports 33 connecting the two. Multiple spray units 1 can be detachably installed on the lower ring 32. This structure allows the mounting frame 3 to form a stable truss structure. The spray units 1 can be flexibly arranged on the lower ring 32 according to the size and shape of the offshore operation area. Their number and position can be adjusted according to specific operational needs, thereby achieving the best spray coverage effect.

[0041] Meanwhile, the detachable installation method of the spray unit 1 (such as installation by means of clips, bolts, etc.) facilitates subsequent maintenance and replacement, and also supports modular design of the system, which is convenient for installation, maintenance and upgrade. If a spray unit 1 fails, it can be removed from the lower ring for repair or replacement with a new unit, without the need for large-scale disassembly of the entire system.

[0042] Optionally, the upper ring 31 and the lower ring 32 are generally made of high-strength metal materials, such as stainless steel or aluminum alloy, to ensure sufficient strength and corrosion resistance in harsh marine environments. The vertical support 33 can be a solid rod-like structure or a hollow tubular structure, with its two ends connected and fixed to the upper ring 31 and the lower ring 32 by welding or bolting.

[0043] Furthermore, during the installation of the installation frame 3, it is lowered to the seabed using a hoisting device. During the recovery of the installation frame 3, the support vessel uses the hoisting device to slowly lift the installation frame 3 to the surface and retrieve it onto the ship. During the recovery process, care is taken to ensure that the installation frame 3 and the jetting unit 1 are not damaged.

[0044] Based on any of the above embodiments, refer to Figure 3 Each spray unit 1 includes a nozzle, an angle adjustment mechanism for adjusting the nozzle angle, and a water pump (not shown in the figure) for supplying spray liquid to the nozzle.

[0045] Specifically, the spraying unit 1 includes a nozzle, an angle adjustment mechanism, and a water pump. The angle adjustment mechanism is used to adjust the angle of the nozzle, and the water pump is used to supply spraying liquid to the nozzle. This structure allows the spraying unit to perform spraying operations at different angles and flow rates according to control commands, thereby flexibly adapting to different operational needs and sea conditions, expanding the operational coverage, and improving the efficiency and flexibility of offshore operations.

[0046] Optionally, nozzles are typically made of wear-resistant and corrosion-resistant materials, such as ceramics or special alloys. Their shape can be round, square, or oval, with different shapes suitable for different spraying requirements.

[0047] Furthermore, the angle adjustment mechanism includes a servo motor and a synchronous belt drive assembly. The servo motor is fixed to the lower ring 32 by fasteners, and the synchronous belt drive assembly connects the output shaft of the servo motor to the nozzle.

[0048] Specifically, when the servo motor is running, power is transmitted to the nozzle through the synchronous belt drive assembly, thereby adjusting the nozzle angle. This allows the spray unit 1 to flexibly adjust the spray angle according to control commands, enabling spray operations at different angles to meet different operational needs. This improves the operational flexibility and adaptability of the multi-point spray system at sea, allowing for better coverage of a wider sea area.

[0049] Servo motors are characterized by high precision and high response speed, enabling precise control of the nozzle angle. A synchronous belt drive assembly connects the servo motor's output shaft to the nozzle. When the servo motor rotates, it drives the nozzle to rotate via the synchronous belt, thus adjusting the nozzle angle. This synchronous belt drive assembly can be of different types, such as V-belts or trapezoidal belts. The water pump, such as a centrifugal pump or plunger pump, delivers the spraying liquid to the nozzle, providing power for the spraying operation. These three components work together: the water pump provides the spraying power, the angle adjustment mechanism controls the spraying direction, and the nozzle sprays the liquid in a suitable manner, achieving spraying operations at different angles and flow rates.

[0050] It should be noted that the nozzle is connected to the water tank on the surface working vessel through a spray pipe, and the water pump sprays the spray liquid in the water tank out of the nozzle through the spray pipe.

[0051] Based on any of the above embodiments, refer to Figure 1 Multiple sludge suction nozzles 2 are spaced apart on the lower ring 32.

[0052] Specifically, multiple mud suction nozzles 2 are spaced apart on the lower ring 32. The mud suction nozzles 2 are used to discharge the sucked mud and sand to the seabed. This allows the mud and sand raised by the jetting operation to be effectively discharged in a timely manner, preventing the accumulation of mud and sand in the working area, ensuring the continuous and efficient operation of the jetting operation, further expanding the system's working range and improving work efficiency.

[0053] It should be noted that the sludge suction nozzle 2 is generally made of wear-resistant materials, such as rubber or polyurethane. Its shape can be funnel-shaped, which facilitates better suction of sludge and sand. The sludge suction nozzle 2 is connected to the sludge discharge pipeline via a pipe, which discharges the sucked-in sludge and sand to a designated location. When the spraying unit 1 performs spraying operations on the seabed, it will raise a large amount of sludge and sand. The sludge suction nozzle 2 can suck in this sludge and sand and then discharge it through the sludge discharge pipeline, preventing sludge and sand from accumulating in the work area, reducing the interference of sludge and sand on the working environment, and improving the cleanliness and efficiency of the spraying operation. At the same time, because the sludge and sand are handled in a timely manner, it also reduces wear and tear on the spraying unit and other equipment, extends the service life of the equipment, and reduces maintenance costs.

[0054] In one specific embodiment provided in this application, the sensor module includes a wind speed sensor, a water flow sensor, and a pressure sensor.

[0055] Specifically, the sensor module includes wind speed sensors, water flow sensors, and pressure sensors. Wind speed sensors can be three-cup anemometers or ultrasonic anemometers, which can measure wind speed at sea in real time. Water flow sensors can be electromagnetic water flow sensors or ultrasonic Doppler water flow sensors, used to measure the speed and direction of water flow. Pressure sensors can be strain gauge pressure sensors or piezoelectric pressure sensors, capable of measuring seabed pressure. These sensors are integrated into the sensor module to monitor sea conditions and operational status in real time, providing accurate data support for the control system. For example, when the wind speed sensor detects an increase in wind speed, the control module can adjust the jetting parameters of the jetting unit based on this data to ensure that the jetting effect is not affected by strong winds. Depending on the requirements, the sensor module may also include other sensors for monitoring sea conditions and operational status.

[0056] Based on any of the above embodiments, the marine multi-point jetting system also includes a remote monitoring module. The remote monitoring module is connected to the control module through wireless communication technology and has data encryption transmission and fault diagnosis functions.

[0057] Specifically, the remote monitoring module connects to the control module via wireless communication technology, such as 5G or satellite communication. The remote monitoring module features encrypted data transmission and fault diagnosis capabilities. It employs data encryption technology and security protocols to ensure the security and reliability of data transmission. For example, during data transmission, a symmetric encryption algorithm is used to encrypt the data, and only the remote monitoring center with the decryption key can decrypt and read the data. Through the remote monitoring module, the system can automatically detect and diagnose potential faults, providing fault warnings and maintenance suggestions. When the system detects an abnormal pressure in a jetting unit, the remote monitoring module will promptly issue a fault warning, analyze the data to identify possible causes of the fault, and provide corresponding maintenance suggestions to reduce maintenance costs and downtime.

[0058] It should also be noted that the remote monitoring module has a user interface, which is set on the work vessel at sea. It supports functions such as remote monitoring, parameter setting, and fault diagnosis, which facilitates operators to monitor and manage the system in real time. It also enables real-time data exchange and command transmission between the user interface and the remote monitoring module through wireless communication technologies (such as 5G and satellite communication).

[0059] Based on any of the above embodiments, the control module uses a high-performance embedded processor as the core control unit, responsible for receiving sensor data, executing control algorithms, and issuing control commands. The control module is connected to the jetting unit 1 and the sensor module via wireless communication technology. After the sensor module collects sea state and operational status data, it transmits the data to the control module. After analysis and processing, the control module calculates appropriate jetting parameters according to a preset algorithm and issues control commands to the jetting unit 1 to adjust parameters such as jetting pressure, flow rate, and angle.

[0060] Based on any of the above embodiments, please refer to Figure 4 The overall architecture of the marine multi-point jetting system and control method shown in the figure includes the following layers and modules:

[0061] Core Control Layer: The high-performance embedded processor (central control unit) serves as the "brain" of the system, responsible for receiving data from various layers, executing control algorithms, and issuing control commands. Specifically, the sensor data receiving interface receives sensor data from the perception layer; the control algorithm execution engine runs advanced control algorithms to analyze and process the sensor data; and the command output module generates and outputs control commands to the execution layer based on the results of the control algorithm.

[0062] The data processing and algorithm module consists of: a real-time data analysis unit that analyzes sensor data in real time to monitor system status and operating environment; a learning optimization engine that continuously optimizes control algorithms and improves system performance through machine learning technology; and a dynamic parameter regulator that dynamically adjusts injection parameters, such as pressure and flow rate, based on the real-time data analysis results.

[0063] User interaction layer: Local HMI interface, providing a local human-machine interface that allows operators to directly monitor and control the spraying system; remote monitoring interface, supporting remote monitoring that allows operators to view system status and operation through remote devices; fault diagnosis system, which monitors system status in real time, promptly detects and diagnoses faults, and provides fault warnings and solutions.

[0065] Execution layer: Intelligent actuators execute spraying operations according to control commands, such as adjusting spraying angle and pressure; Parametric control interface provides a parametric control interface, allowing operators to adjust spraying parameters according to operational needs; Feedback adjustment loop adjusts spraying operations in real time through sensor feedback to ensure operational effectiveness and safety;

[0067] The different layers are connected and interact through different interfaces and modules, together forming a complete architecture for a marine multi-point jetting system and control method.

[0068] Based on any of the above embodiments, please refer to Figure 5 This diagram illustrates the flow of data within the system. It includes components such as the execution layer, user interaction layer, core control layer, perception layer, communication layer, and data processing module.

[0069] Core Control Layer: As the central component of the system, it maintains bidirectional information flow with each other. It receives sensor data from the perception layer, analyzes and processes it through the data processing and algorithm module, and then generates control commands to send to the execution layer. Simultaneously, it also receives commands and feedback from the user interaction layer, as well as remote communication data from the communication layer.

[0070] User Interaction Layer: Connects to the core control layer via two-way human-machine interaction. Operators can interact with the system through a local HMI interface or a remote monitoring interface, sending control commands, viewing system status and operational conditions, and receiving fault warnings and solutions.

[0071] Communication Layer: Connects to the core control layer via two-way remote communication. It supports remote interaction modules and multi-mode communication units, ensuring that operators can communicate with the system through remote devices and guaranteeing the security and reliability of data transmission.

[0072] Perception Layer: Connected to the core control layer via real-time data streams. Multimodal sensor networks and environmental sensing arrays monitor sea conditions, operational status, and equipment status in real time, and send the data to the core control layer through a data preprocessing unit.

[0073] Execution layer: Connected to the core control layer via control commands. The intelligent actuator performs the jetting operation according to the control commands sent by the core control layer, and feeds back the operation status to the core control layer through a feedback adjustment loop.

[0074] Data processing module: This module can be integrated into the core control layer and is responsible for data processing and functions such as data analysis, learning optimization, and dynamic parameter adjustment within the algorithm module. The data processing module connects to the core control layer through bidirectional parameter interaction, ensuring real-time data processing and accurate generation of control commands.

[0075] The implementation principle of a multi-point spraying system for marine applications according to this application is as follows: A mounting frame 3 provides a stable support structure for the spraying unit 1, allowing it to be rationally positioned within the marine operation area. A sensor module collects sea state and operational status data in real time and feeds this data back to the control module. Based on the received data, the control module uses advanced algorithms to calculate the optimal spraying parameters and controls the spraying unit 1 to perform spraying operations. A remote monitoring module enables remote real-time monitoring and fault diagnosis of the system, facilitating system management and maintenance by operators far from the operational site. By installing a mud suction nozzle 2 on the lower ring 32, mud and sand are promptly discharged during spraying operations, reducing interference from mud and sand on the operational environment and improving the cleanliness and efficiency of the spraying operation. Simultaneously, timely mud and sand treatment reduces wear on the spraying unit and other equipment, extending equipment lifespan and lowering maintenance costs. Through the coordinated work of all components, the entire system significantly improves the efficiency, scope, and flexibility of marine operations while ensuring operational safety, representing a significant improvement over traditional marine spraying systems.

[0076] This utility model also discloses a control method for a marine multi-point jetting system, applied to the aforementioned marine multi-point jetting system, wherein the control method includes the following steps:

[0077] S1. Control sensor module to collect sea state parameters in real time, including wind speed, water flow speed and seabed pressure;

[0078] S2. Establish a digital model of the working area based on the parameters, and determine the initial values ​​of the spray target distance and spray angle of the spray unit 1.

[0079] S3. During operation, the spraying effect and operation status of spraying unit 1 are continuously monitored. The control module adjusts the spraying parameters and operation mode of the spraying unit in real time based on the monitoring results.

[0080] Specifically, in step S1, the various sensors in the sensor module, including the wind speed sensor, water flow sensor, and pressure sensor, begin to operate. The wind speed sensor measures the wind speed at sea in real time, the water flow sensor measures the speed and direction of the water flow, and the pressure sensor measures the pressure on the seabed. These sensors transmit the collected data to the control module. During this process, to ensure data accuracy, the sensors need to be calibrated periodically. For example, standard anemometers, water flow meters, and pressure gauges can be used to calibrate the sensors at regular intervals to ensure that the errors in their measurements are within acceptable limits.

[0081] In step S2, the Monte Carlo method is used to simulate the jetting effect under different sea conditions, and the optimal jetting parameters of the jetting unit are selected. After receiving the sea state parameters from the sensors, the control module uses this data in conjunction with the Monte Carlo method to build a digital model of the operating area. The Monte Carlo method is a statistical method based on random sampling. Through a large number of random simulation experiments, it calculates the jetting effect of the jetting unit under different sea conditions and combines historical data to conduct a comprehensive analysis of the operating environment. For example, it simulates the coverage area, jetting force, and other parameters of the jetting unit when performing jetting with different jetting target distances and jetting angles under different wind speeds, water flow velocities, and seabed pressures. Then, based on the simulation results, the optimal jetting parameters are selected as the initial values ​​for the jetting target distance and jetting angle.

[0082] In step S3, the sensor module continuously monitors the spraying distance, coverage area, energy consumption, and other spraying effect and operational status data of the spraying unit. The control module compares these monitoring results with preset ideal values. If the spraying effect is found to be unsatisfactory, such as insufficient spraying distance or coverage area, the control module will promptly adjust the spraying parameters of the spraying unit, such as increasing spraying pressure or adjusting the spraying angle. If excessive energy consumption is detected, the control module will adjust the operational mode, such as reducing unnecessary operation of the spraying unit.

[0083] The control method of the above-mentioned marine multi-point jetting system establishes an accurate digital model by collecting sea state parameters in real time, determines reasonable initial jetting parameters, continuously monitors during operation, and adjusts jetting parameters and operation mode in real time based on monitoring results, thus ensuring the high efficiency and stability of jetting operation.

[0084] The control method of the marine multi-point jetting system provided by this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0085] Based on any of the above embodiments, the control method further includes:

[0086] When the pressure value of the jetting unit is lower than the set threshold for 5 consecutive seconds, the fault diagnosis program is immediately triggered. The fault diagnosis program includes:

[0087] The system compares historical operating data to locate fault modules; automatically generates maintenance suggestions and spare parts lists; and uploads diagnostic results to the remote monitoring module via an encrypted protocol.

[0088] Specifically, when the pressure value of jetting unit 1 falls below a set threshold for 5 consecutive seconds, a fault diagnosis program is immediately triggered. This program includes comparing historical operating data to locate the faulty module, automatically generating maintenance suggestions and a spare parts list, and uploading the diagnostic results to the remote monitoring module via an encrypted protocol. When the pressure sensor of the jetting unit detects that the pressure value is below the set threshold for 5 consecutive seconds, it indicates a potential fault. The control module retrieves historical operating data, compares it with the current situation, and identifies the module that may be malfunctioning, such as a water pump failure or pipe blockage. Then, based on the fault situation, it automatically generates maintenance suggestions and a list of spare parts that need to be replaced. Finally, the diagnostic results are uploaded to the remote monitoring module via an encrypted protocol, allowing operators to promptly understand the fault situation and take appropriate action.

[0089] It should also be noted that the installation frame 3 and the spray unit 1 are set according to the size and shape of the offshore operation area. The number and position of the spray units can be adjusted according to specific operational needs to achieve the best spray coverage effect. For example, if an operation area with a diameter of 4m needs to be established, 8 spray units can be arranged to form an array layout.

[0090] Based on any of the above embodiments, upon completion of the spraying operation, a stop command is issued via the remote monitoring module. Spraying unit 1 stops spraying, the dredging pump stops operating, and the dredging nozzle 2 stops discharging dredging fluid. The mother vessel uses hoisting equipment to slowly lift the installation frame 3 to the water surface and recover it onto the ship. During the recovery process, ensure that the installation frame 3 and spraying unit 1 are not damaged. After recovery, a comprehensive inspection and maintenance of the spraying system is performed. Residues in the nozzles and pipelines are cleaned, and the wear of spraying unit 1 and sensors is inspected; necessary repairs and replacements are performed. Simultaneously, data backup and system updates are performed on the intelligent control system and remote monitoring module.

[0091] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0092] The above provides a detailed description of the marine multi-point jet spray system provided by this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this utility model.
