[0030] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0031] Figure 1 is a schematic diagram of an exemplary implementation of a fire extinguishing method for an offshore wind turbine converter shown in the present application, such as Figure 1 As shown, the fire extinguishing method of the offshore wind turbine converter comprises the following steps:

[0032] S101, acquiring fire-related parameters corresponding to the offshore wind turbine converter based on a fire warning sensor installed on the offshore wind turbine converter.

[0033] Temperature sensors, smoke sensors and gas sensors are installed at key parts of offshore wind turbine converters (such as electrical control boxes, battery packs, inverters, etc.). These sensors can monitor the temperature, smoke concentration and concentration of harmful gases (such as CO, CO2, etc.) in the converter working environment in real time.

[0034] S102: Determine whether the converter of the offshore wind turbine generator set is in a fire state according to fire-related parameters.

[0035] For example, when the temperature exceeds a certain safety threshold, it is determined that the offshore wind turbine converter is in a fire state.

[0036] For example, when the smoke concentration reaches a preset standard, it is determined that the offshore wind turbine converter is in a fire state.

[0037] For example, when the concentration of harmful gases reaches a preset standard, it is determined that the offshore wind turbine converter is in a fire state.

[0038] Optionally, through the integrated fire warning algorithm, a comprehensive analysis of multiple sensor data is performed, combined with the equipment operation history data and compared with the normal range to determine whether there is a possibility of fire. For example, a sharp increase in temperature accompanied by an increase in smoke concentration indicates that a fire may have occurred.

[0039] S103, in response to determining that the offshore wind turbine converter is in a fire state, starting a fire extinguishing device and generating fire alarm information, and sending the fire alarm information to a control unit.

[0040] When a fire is confirmed, the fire extinguishing device is automatically activated.

[0041] Among them, the fire extinguishing device can adopt gas fire extinguishing, sprinkler fire extinguishing or foam fire extinguishing schemes, and the specific choice depends on the type of converter and the working environment.

[0042] S104, the control unit processes the fire alarm information to obtain a fire location, and the control unit controls a fire extinguishing device to spray and extinguish the fire at the fire location.

[0043] Among them, the control unit is mainly used to control the fire extinguishing device to achieve precise fire extinguishing.

[0044] Based on the sensor data provided in the fire alarm information, the control unit can quickly locate the fire. Once the fire location is confirmed, the control unit sends instructions to the fire extinguishing device to spray the fire extinguishing agent or gas in a targeted manner to accurately extinguish the fire and avoid wasting resources.

[0045] The embodiment of the present application proposes a fire extinguishing method for an offshore wind turbine converter, including: obtaining fire-related parameters corresponding to the offshore wind turbine converter based on the fire warning sensor installed on the offshore wind turbine converter; judging whether the offshore wind turbine converter is in a fire state according to the fire-related parameters; in response to judging that the offshore wind turbine converter is in a fire state, starting the fire extinguishing device and generating fire alarm information, and sending the fire alarm information to the control unit; processing the fire alarm information based on the control unit to obtain the fire location, and controlling the fire extinguishing device based on the control unit to spray and extinguish the fire at the fire location. The present application can effectively intervene in the early stage of a fire through a real-time monitoring and automated response system, reduce the spread of the fire and damage to the equipment, reduce the interference and delay of human factors in firefighting work, and improve the overall response speed and fire extinguishing effect; the control unit can accurately locate the fire area to ensure the efficiency of the fire extinguishing operation.

[0046] Figure 2 is a schematic diagram of an exemplary implementation of a fire extinguishing method for an offshore wind turbine converter shown in the present application, such as Figure 2 As shown, the fire extinguishing method of the offshore wind turbine converter comprises the following steps:

[0047] S201, based on the fire warning sensor installed on the offshore wind turbine converter, the fire related parameters corresponding to the offshore wind turbine converter are collected, the fire warning sensor includes a smoke detector and a temperature sensor, and the fire related parameters include the real-time smoke concentration collected by the smoke detector and the real-time temperature value collected by the temperature sensor.

[0048] Smoke detectors and temperature sensors are installed at key locations around the converter of offshore wind turbines (such as electrical control boxes, battery packs, inverters, etc.). Smoke detectors are mainly responsible for detecting smoke concentration in the air, while temperature sensors are used to monitor temperature changes in the surrounding environment in real time.

[0049] S202: In response to the real-time smoke concentration being greater than a concentration threshold and the real-time temperature value being greater than a temperature threshold, determining that the offshore wind turbine converter is in a fire state.

[0050] Set reasonable safety thresholds for smoke concentration and temperature. For example, when the real-time smoke concentration exceeds 100ppm and the real-time temperature value exceeds 70℃, it indicates a fire risk and is marked as on fire.

[0051] S203, in response to determining that the offshore wind turbine converter is in a fire state, starting a fire extinguishing device and generating fire alarm information, and sending the fire alarm information to a control unit.

[0052] S204: The control unit processes the fire alarm information to obtain a fire location, and the control unit controls a fire extinguishing device to spray and extinguish the fire at the fire location.

[0053] S205, in response to monitoring that the real-time smoke concentration is less than or equal to the concentration threshold, and the real-time temperature value is less than or equal to the temperature threshold, shutting down the fire extinguishing device.

[0054] Continuously monitor smoke concentration and temperature changes to determine whether the fire source has been extinguished. If the real-time smoke concentration is less than or equal to the concentration threshold, and the real-time temperature value is less than or equal to the temperature threshold, the fire is considered to have been extinguished, and the fire extinguishing device is directly turned off to avoid the waste of fire extinguishing agents and unnecessary resource consumption. At this time, the relevant alarm information will be updated to indicate that the fire has been extinguished.

[0055] The embodiment of the present application can effectively intervene in the early stage of a fire through real-time monitoring and automated response systems, reduce the spread of fire and damage to equipment, reduce interference and delays in firefighting work caused by human factors, and improve the overall response speed and fire-fighting effect; the control unit can accurately locate the fire area and ensure the efficiency of the fire-fighting operation.

[0056] Furthermore, the fire extinguishing status parameters corresponding to the converter of the offshore wind turbine are obtained in real time (including smoke concentration, temperature value and the status of the fire extinguishing device, such as the amount of fire extinguishing agent released, the start and stop status of the fire extinguishing device, etc.); the fire alarm information and fire extinguishing status parameters are sent to the corresponding terminal device of the staff. After the terminal device receives the fire alarm information, it will immediately display detailed information such as the location, type and risk level of the fire. After the terminal device receives the fire extinguishing status parameters, the staff can view real-time data such as whether the fire extinguishing device has been enabled, the amount of fire extinguishing agent released, and the progress of fire extinguishing.

[0057] In some implementations, staff can remotely control the opening / closing of the fire extinguishing device or adjust parameters (such as the amount of fire extinguishing agent released) through the terminal device.

[0060] The judgment module 302 is used to judge whether the converter of the offshore wind turbine is in a fire state according to fire-related parameters.

[0061] The first control module 303 is used to start the fire extinguishing device and generate fire alarm information in response to determining that the offshore wind turbine converter is in a fire state, and send the fire alarm information to the control unit.

[0062] The second control module 304 is used to process the fire alarm information based on the control unit to obtain the fire location, and control the fire extinguishing device based on the control unit to spray and extinguish the fire at the fire location.

[0063] Through real-time monitoring and automated response systems, this device can effectively intervene in the early stages of a fire, reduce the spread of fire and damage to equipment, reduce interference and delays in firefighting caused by human factors, and improve overall response speed and firefighting effectiveness; the control unit can accurately locate the area where the fire occurs, ensuring the efficiency of the firefighting operation.
