Description

Technical Field

[0001] This invention belongs to the technical field of fire extinguishing auxiliary equipment for offshore booster stations, specifically relating to a turbofan cannon system with a wide range of water mist coverage capabilities and its operation method. Background Technology

[0002] In existing technologies, offshore substations are constructed at sea, housing high-voltage AC transformers, high-voltage DC converters, and related living facilities. Their primary function is to transmit electricity from offshore wind turbines to the onshore power grid, while also converting the voltage of the wind turbines or wind farms. As a crucial transmission medium, cables are essential for the safety and stability of offshore substations, especially given the complex and variable marine environment.

[0003] Currently, offshore substations primarily rely on traditional fire suppression equipment to combat cable fires. However, these systems have revealed numerous problems in practical application. The spray range of conventional fire suppression equipment at offshore substations is limited, and the precision in controlling the spray angle and range is poor, making it difficult to accurately deliver the extinguishing agent to the ignition point of the cable fire. In the event of a relatively large-scale fire at an offshore substation, the existing fire suppression equipment may be insufficient to cover the entire fire area, potentially requiring multiple devices and manual operation, reducing fire suppression efficiency, failing to meet requirements, and possibly causing significant losses. Summary of the Invention

[0004] This invention provides a turbofan cannon system with a wide-area water mist coverage capability and its operation method. The purpose is to solve the problem that the fire extinguishing equipment currently equipped at offshore substations cannot spray a wide area of ​​the fire when encountering a relatively large fire at the offshore substation, which may require multiple devices and a lot of manual operation, and the fire extinguishing efficiency needs to be further improved.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This invention provides a turbofan gun system with a wide-area water mist coverage capability. The turbofan gun system includes a turbofan gun unit and an azimuth control and adjustment unit, wherein: The turbofan cannon unit includes a housing and an electric motor installed therein. The output shaft of the drive motor is equipped with a spiral turbine fan. The airflow direction of the spiral turbine fan faces one end of the housing, and the other end of the housing can be connected to an external spraying medium device. The orientation control adjustment unit is located at the bottom of the container and is movably connected to the side wall of the container; the orientation control adjustment unit can control the pitch angle at both ends of the container and can control the rotation angle of the container in the horizontal direction; the pitch angle range is controlled to be no greater than 75°, and the rotation angle range is controlled to be no greater than 355°.

[0006] In some embodiments, the accommodating cylinder rotates in the horizontal direction within a range of +177.5° to -177.5°.

[0007] In some implementations, the pitch angle range at both ends of the receiving cylinder is controlled to be +45° to -30°.

[0008] In some embodiments, the power of the motor 2 is 15KW and the speed is 3000r / min.

[0009] Furthermore, when connected to an external spraying medium device, the spiral turbine fan can drive the spraying medium to be sprayed out from one end of the container, with a spraying range of 25~35m.

[0010] In some embodiments, the container is connected to an orientation control adjustment unit via a rotating shaft, and the orientation control adjustment unit controls the rotation angle of the container by controlling the rotating shaft.

[0011] In some implementations, when connected to an external spray medium device, the operating pressure range of the turbofan cannon unit is controlled to be 1.2-1.6 MPa.

[0012] In some embodiments, the orientation control adjustment unit includes a rotary seat and an angle adjustment mechanism, and a controller disposed thereon, the controller being used to control the rotary seat and the angle adjustment mechanism to adjust the rotation angle and pitch angle of the receiving cylinder.

[0013] In some embodiments, the turbofan gun system also includes a support base, with the azimuth control adjustment unit detachably mounted on the support base.

[0014] The present invention also provides an operating method for a turbofan gun system with a wide-area water mist coverage capability, comprising the following steps: The turbofan cannon unit is connected to an external power supply and an external spray medium device. The parameters of the turbofan cannon unit and the azimuth control adjustment unit are set. The azimuth control adjustment unit adjusts the pitch angle and horizontal rotation angle of the turbofan cannon unit. The motor inside the turbofan gun unit is started, and the propeller fan blows the spray medium out from one end of the container. The rotation and pitch angles of the container are controlled in real time by the azimuth control adjustment unit.

[0015] Compared with the prior art, the turbofan gun system and its operation method with a wide range of water mist coverage capability of the present invention have the following beneficial effects: This invention discloses a turbofan cannon system with a wide-area water mist coverage capability. The turbofan cannon system includes a turbofan cannon unit and an azimuth control and adjustment unit. The turbofan cannon unit includes a housing and an electric motor housed within it. The output shaft of the drive motor is equipped with a spiral turbine fan, whose airflow direction faces one end of the housing. The other end of the housing can be connected to an external spray medium device. The azimuth control and adjustment unit is located at the bottom of the housing and movably connected to its side wall. The azimuth control and adjustment unit can control the pitch angle at both ends of the housing and the rotation angle of the housing in the horizontal direction. The pitch angle is controlled to be no greater than 75°, and the rotation angle is controlled to be no greater than 355°. This invention achieves the guided spraying of the spray medium through the cooperation of the turbofan cannon unit and the azimuth control and adjustment unit. The turbofan cannon unit of this invention has a built-in electric motor that drives the spiral turbine fan to rotate at high speed, generating a strong airflow. This airflow, guided by a specially designed housing, blows out the water mist or other medium provided by the external spray medium device connected to the other end of the housing.

[0025] How can we provide fire extinguishing equipment with better control over the spray angle and range, so as to accurately spray the extinguishing medium to the ignition point of the cable fire and spray a wide area of ​​the fire area, thereby improving operational efficiency?

[0026] like Figure 1 and Figure 2 As shown, the present invention discloses a turbofan gun system with a wide-area water mist coverage capability. The turbofan gun system includes a turbofan gun unit and an azimuth control and adjustment unit, wherein: The turbofan cannon unit includes a housing 1 and an electric motor 2 installed therein. The output shaft of the drive motor 2 is equipped with a spiral turbine fan 3. The air blowing direction of the spiral turbine fan 3 faces one end of the housing 1, and the other end of the housing 1 can be connected to an external spraying medium device. The orientation control adjustment unit is located at the bottom of the accommodating cylinder 1 and is movably connected to the side wall of the accommodating cylinder 1; the orientation control adjustment unit can control the pitch angle at both ends of the accommodating cylinder 1 and can control the rotation angle of the accommodating cylinder 1 in the horizontal direction; the pitch angle range is controlled to be no greater than 75°, and the rotation angle range is controlled to be no greater than 355°.

[0027] The turbofan cannon system of the present invention is configured to allow the housing 1 to rotate vertically and horizontally. When connected to an external spray medium device, the motor 2 drives the spiral turbine fan 3 to rotate and generate airflow, which sprays the spray medium out in the adjusted direction, forming a relatively large area of ​​water mist coverage. It is suitable for fire extinguishing needs in various complex environments, especially for fire fighting at offshore substations.

[0028] In some embodiments, the turbofan cannon system of the present invention, which has a wide range of water mist coverage, allows the receiving cylinder 1 to rotate within a horizontal angle range of +177.5° to -177.5°. The rotary seat and angle adjustment mechanism within the azimuth control adjustment unit of the present invention, through precision transmission and limiting, ensure that the receiving cylinder 1 can rotate smoothly and stably within the horizontal range of +177.5° to -177.5°. This wide range of horizontal rotation capability significantly improves the system's flexibility, enabling it to adapt to sites of different shapes and sizes, and ensuring that the water mist can uniformly cover the entire fire extinguishing area.

[0029] Furthermore, the adjustable pitch angle range at both ends of the receiving cylinder 1 of the present invention is +45° to -30°. The adjustment of the pitch angle also relies on the azimuth control adjustment unit, enabling precise control of the pitch angle of the receiving cylinder 1. Adjusting the pitch angle allows the system to spray water mist at targets at different heights, improving the targeting and efficiency of the operation. Simultaneously, by reasonably setting the pitch angle range, the reduction in spraying effect and safety hazards caused by excessively large angles are avoided.

[0030] In some embodiments, the motor 2 selected in the turbofan gun system of the present invention has a power of 15KW and a speed of 3000r / min. The power and speed of the motor 2 directly determine the blowing capacity and efficiency of the spiral turbine fan 3. The power of 15KW and the speed of 3000r / min can generate a sufficiently strong airflow to ensure that the medium such as water mist can be effectively blown out and cover the target area. The present invention selects a high-power and high-speed motor 2 to ensure the system's strong blowing capacity and high working efficiency, so that the water mist can cover the target area uniformly over a long distance.

[0031] Based on the aforementioned design, when connected to an external spray medium device, the spiral turbine fan 3 can drive the spray medium to be ejected from one end of the container 1, with a spray range of 25-35m. Since the spray range is affected by various factors, including the power of the motor 2, the design of the spiral turbine fan 3, the properties of the spray medium, and the outlet size of the container 1, this invention allows for precise control of the spray medium range, ensuring that the water mist accurately reaches the target area, avoiding unnecessary waste and pollution. The adjustable range also improves the system's adaptability, allowing a single system to extinguish fires in an area, simplifying the workflow.

[0032] Furthermore, when connected to an external spraying medium device, the operating pressure range of the turbofan cannon unit of the present invention is 1.2~1.6 MPa. The present invention achieves precise control of the operating pressure by adjusting the pressure exerted on the spraying medium when it is compressed and ejected within the receiving cylinder 1. Appropriate operating pressure ensures that the spraying medium can be ejected evenly and powerfully, improving the water mist coverage effect.

[0033] The container cylinder 1 of the present invention is connected to an orientation control and adjustment unit via a rotating shaft 4. The orientation control and adjustment unit adjusts the rotation angle of the container cylinder 1 by controlling the rotating shaft 4. The rotating shaft 4 of the present invention can not only bear the weight of the container cylinder 1 and the torque during rotation, but also ensure the stability and reliability of the container cylinder 1 during rotation, making the rotation of the container cylinder 1 more stable.

[0034] In some embodiments, the orientation control adjustment unit of the present invention includes a rotary seat and an angle adjustment mechanism, and a controller disposed thereon. The controller is used to control the rotary seat and the angle adjustment mechanism to adjust the rotation angle and pitch angle of the receiving cylinder 1. In the present invention, the rotary seat serves as a support structure for the receiving cylinder 1. The angle adjustment mechanism is provided with a transmission component, which may be, but is not limited to, a hydraulic assembly, a worm gear, a lead screw and nut, etc. The transmission component is connected to a rotating shaft to achieve precise control of the pitch angle and horizontal rotation angle of the receiving cylinder 1. The controller is responsible for receiving commands and controlling the actions of these mechanisms. In some embodiments, the controller of the present invention can precisely control the rotation and pitch angles of the receiving cylinder according to preset parameters and instructions or data collected in the actual environment, thereby improving the efficiency and accuracy of the operation. The present invention improves the reliability and maintainability of the system by configuring the controller to achieve functions such as remote monitoring and fault diagnosis.

[0035] In some embodiments, the turbofan gun system of the present invention further includes a support base 5, and the azimuth control adjustment unit is detachably mounted on the support base 5. The support base 5 serves as a support structure for the turbofan gun system and can be connected to the azimuth control adjustment unit via bolts, flanges, or other connectors. The azimuth control adjustment unit is detachably mounted on the support base 5, allowing for easy disassembly and installation onto the support base 5 when the turbofan gun system needs to be moved or reinstalled, facilitating system transportation and disassembly.

[0036] This invention also provides a control method for a turbofan gun system with a wide-area water mist coverage capability, the method comprising the following steps: The turbofan cannon unit of the present invention connects the external spray medium equipment to the other end of the container cylinder 1. The pitch angle of the two ends of the container cylinder 1 is controlled and adjusted by the azimuth control and adjustment unit. The pitch angle is controlled within a range of no more than 75°. The rotation angle of the container cylinder 1 in the horizontal direction is controlled within a range of no more than 355°. Specifically, the rotation angle of the container cylinder 1 in the horizontal direction is +177.5° to -177.5°, and the pitch angle of the two ends of the container cylinder 1 is +45° to 30°. Start the motor 2 in the turbofan gun unit, so that the output shaft of the motor 2 drives the spiral turbine fan 3 to rotate, and the air blowing direction of the spiral turbine fan 3 faces one end of the housing cylinder 1; The operating pressure of the turbofan gun unit is maintained within the range of 1.2~1.6MPa. The propulsive action of the spiral turbine fan 3 drives the spray medium to be ejected from one end of the housing 1, forming a water mist coverage. The range of the spray medium is controlled within the range of 25~35m. The controller in the azimuth control adjustment unit further precisely adjusts the rotation and elevation angles of the housing swivel and angle adjustment mechanism to achieve the required water mist coverage range and angle.

[0037] This invention first requires connecting the turbofan cannon unit to an external power source and spray medium equipment. Then, parameters such as the motor power, speed, and spray medium range are set according to actual needs. Next, the pitch and horizontal rotation angles of the receiving cylinder are adjusted via a controller. Finally, the motor is started, and the spray effect is observed to ensure it meets requirements. If adjustments to the spray effect are needed, they can be achieved by modifying parameters or readjusting the angle. This invention, based on a turbofan cannon system, ensures that the system operates according to a predetermined method and achieves efficient and uniform water mist coverage of the target area. Furthermore, the system is easy to operate and perform, further improving the efficiency and accuracy of the turbofan cannon system, thus providing safety assurance for offshore booster stations.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention according to the description and above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, based on the disclosed technical content, are equivalent embodiments of the present invention. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the present invention.
