Description
Technical Field
[0001] This invention belongs to the technical field of auxiliary equipment for cable fire prevention and extinguishing, and specifically relates to a rotary mechanism for a turbofan cannon based on hydraulic power drive and its operation method. Background Technology
[0002] Currently, offshore substations primarily rely on traditional fire suppression equipment to handle fires involving electrical components such as cables. However, these systems have revealed numerous problems in practical applications. Among existing technologies, turbofan cannons, as high-performance fire suppression devices, rely heavily on stability and accuracy to improve extinguishing efficiency. Current turbofan cannon rotary mechanisms typically employ mechanical transmission methods, such as gear or chain drives. However, these mechanical transmission methods may suffer from issues like high vibration, severe wear, relatively high maintenance costs, and limited control precision in practical applications. Vibration problems can lead to loosening or damage to internal components, reducing system reliability and lifespan. Wear problems result in decreased transmission efficiency, increased energy consumption, and the resulting debris can contaminate the system's internal components, further exacerbating malfunctions. Furthermore, the limited control precision of traditional mechanical transmission methods makes it difficult to meet the requirements of high precision, high speed, and high flexibility.
[0003] As an improvement, hydraulic systems, as a highly efficient and stable transmission method, use liquid as the working medium to transmit energy and signals, offering advantages such as high control precision, smooth transmission, low noise, and low maintenance costs. Therefore, applying hydraulic systems to the slewing mechanism of turbofan guns has the potential to solve the problems existing in current mechanical transmission methods and improve the performance of turbofan guns. However, current turbofan gun slewing mechanisms still have certain risks of vibration and wear during slewing, making it difficult for turbofan guns to achieve smooth and precise slewing movements. Furthermore, the applicability of turbofan guns in complex and variable marine environments needs further improvement. Summary of the Invention
[0004] This invention provides a hydraulically driven turbofan gun slewing mechanism and its operating method, aiming to solve the problems that current turbofan gun slewing mechanisms still have certain vibration and wear risks during slewing, making it difficult for turbofan guns to achieve stable and precise slewing movements, and the applicability of turbofan guns in complex and ever-changing marine environments needs to be further improved.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: This invention provides a hydraulically driven turbofan gun slewing mechanism, which includes a hydraulic power unit, a slewing unit, and a control unit. The output of the hydraulic power unit is connected to the slewing unit, and the control unit controls the hydraulic power unit to drive the slewing unit. The turbofan gun slewing mechanism can be installed on the turbofan gun equipment. When installed, the slewing unit can be connected to the turbofan gun part so that the turbofan gun slewing mechanism can drive the turbofan gun part to perform slewing motion. The hydraulic power unit has an oil tank and hydraulic lines connected to it. A drive assembly and a hydraulic motor are installed on the hydraulic lines. The output shaft of the hydraulic motor is connected to the rotary unit. The drive assembly can drive the hydraulic motor to rotate, which in turn drives the rotary unit to rotate.
[0006] In some embodiments, the drive assembly includes a gear pump with one end connected to an oil tank and the other end connected to a hydraulic motor. The gear pump is equipped with an explosion-proof motor, which is powered by an external power source to provide power to the gear pump.
[0007] Furthermore, a stacked solenoid valve is installed between the gear pump and the hydraulic motor. The stacked solenoid valve is used to regulate the flow rate of liquid in the hydraulic pipeline, thereby controlling the movement speed of the hydraulic motor.
[0008] Furthermore, the superimposed solenoid valve is also equipped with an explosion-proof solenoid valve, which is used to control the movement of the valve core through electromagnetic force, thereby changing the flow path of the liquid in the hydraulic pipeline, so as to control the reversal or start / stop of the hydraulic power unit.
[0009] Furthermore, a balance valve is installed between the superimposed solenoid valve and the hydraulic motor. The balance valve is used to control the flow rate of the liquid in the hydraulic pipeline to a constant value when the system is not in operation.
[0010] In some implementations, the hydraulic lines are also equipped with a suction filter, which is installed near the oil tank in order to filter the liquid entering the hydraulic lines.
[0011] Furthermore, a breather plug is installed on the top of the fuel tank to balance the air pressure inside and outside the fuel tank.
[0012] In some implementations, the hydraulic lines of the hydraulic power unit are also equipped with a pressure gauge and a relief valve. The pressure gauge is used to monitor the liquid pressure of the hydraulic power unit in real time, and the relief valve is used to select whether to open or close based on the pressure value of the pressure gauge, thereby maintaining the working pressure of the hydraulic lines.
[0013] In some embodiments, the rotary unit includes a rotary body, the output shaft of a hydraulic motor is connected to the lower end of the rotary body, and the upper end of the rotary body is provided with a connection position, which can be connected to the structure to be rotated.
[0014] This invention also discloses an operation method for a hydraulically driven turbofan gun slewing mechanism, comprising the following steps: Check and verify the airtightness of each component in the turbofan gun slewing mechanism, and connect the turbofan gun slewing mechanism to an external power source. Turn on the power and control the drive component of the hydraulic power unit through the control unit. The drive component delivers liquid to the hydraulic motor through the hydraulic pipeline and controls the movement speed of the hydraulic motor, thereby driving the rotary unit to move. The hydraulic power unit achieves reversal or start / stop by changing the flow path of the liquid in the hydraulic pipeline; when not in operation, the liquid flow rate in the hydraulic pipeline is kept constant by the controller.
[0015] Compared with the prior art, the present invention, a hydraulically driven turbofan gun slewing mechanism and its operating method, has the following advantages: This invention discloses a hydraulically driven turbofan gun slewing mechanism, comprising a hydraulic power unit, a slewing unit, and a control unit. The output end of the hydraulic power unit is connected to the slewing unit, and the control unit controls the hydraulic power unit to drive the slewing unit. The slewing mechanism can be installed on a turbofan gun device. When installed, the slewing unit is connected to the turbofan gun section, allowing the slewing mechanism to drive the turbofan gun section to rotate. The hydraulic power unit has an oil tank and hydraulic lines connected to it. A drive assembly and a hydraulic motor are installed on the hydraulic lines. The output shaft of the hydraulic motor is connected to the slewing unit, and the drive assembly drives the hydraulic motor to rotate, thereby driving the slewing unit to rotate. This invention's turbofan gun slewing mechanism, by integrating a high-performance hydraulic power unit, a slewing unit, and a control unit, achieves precise control and wide-range coverage of the turbofan gun's horizontal slewing angle, significantly improving the flexibility and effectiveness of responding to fires at offshore substations. This invention employs a hydraulic power unit to directly drive the rotary motor, ensuring that the turbofan cannon can stably and rapidly complete horizontal rotation in complex and ever-changing marine environments, achieving comprehensive coverage of the fire-extinguishing water mist.

[0025] How can the turbofan gun, when applied to a marine booster station in a complex and ever-changing marine environment, be stably and quickly controlled by the precise hydraulic system to complete the full range of rotational movements and achieve all-round coverage of the fire extinguishing water mist?
[0026] like Figure 1 and Figure 2 As shown, this invention discloses a hydraulically driven turbofan gun slewing mechanism, comprising a hydraulic power unit, a slewing unit, and a control unit. The output end of the hydraulic power unit is connected to the slewing unit, and the control unit is used to control the hydraulic power unit to drive the slewing unit. The turbofan gun slewing mechanism can be installed on the turbofan gun equipment. When installed, the slewing unit can be connected to the turbofan gun part so that the turbofan gun slewing mechanism can drive the turbofan gun part to perform slewing motion. The hydraulic power unit has an oil tank 1 and hydraulic lines connected to it. A drive assembly and a hydraulic motor 1 are installed on the hydraulic lines. The output shaft of the hydraulic motor 2 is connected to the rotary unit. The drive assembly can drive the hydraulic motor 2 to rotate, thereby driving the rotary unit to rotate.
[0027] The turbofan gun slewing mechanism of this invention achieves slewing motion through the cooperation of a hydraulic power unit, a slewing unit, and a control unit. The output end of the hydraulic power unit is connected to the slewing unit, and the control unit drives the slewing unit by controlling the hydraulic power unit. When applied to a turbofan gun, the slewing unit can be connected to the turbofan gun section to realize the slewing motion of the turbofan gun. The hydraulic power unit used in this invention provides powerful driving force, and its reasonable and smooth power transmission ensures stable and rapid slewing motion of the turbofan gun section. The control unit enables precise control of the slewing motion to meet different environmental requirements, especially those of offshore booster stations. When this turbofan gun slewing mechanism is installed on various turbofan gun equipment, it can improve the flexibility and adaptability of the equipment.
[0028] In some embodiments, the drive assembly of the present invention includes a gear pump 3 connected at one end to an oil tank 1, and the other end of the gear pump 3 connected to a hydraulic motor 2. The gear pump 3 is equipped with an explosion-proof motor 4, which is powered by an external power source to provide power to the gear pump 3. The present invention improves the safety of the equipment by using the explosion-proof motor 4, especially in marine environments where it is difficult to control flexibly. The gear pump can stably deliver liquid from the oil tank 1 to the hydraulic motor 2, ensuring the continuity and stability of the rotary motion.
[0029] More preferably, a superimposed solenoid valve 5 is also provided between the gear pump 3 and the hydraulic motor 2 in the hydraulic pipeline. The superimposed solenoid valve 5 is used to regulate the fluid flow rate in the hydraulic pipeline, thereby controlling the movement speed of the hydraulic motor 2. By adjusting the fluid flow rate, this invention can achieve precise control of the movement speed of the hydraulic motor 2, meeting different speed and precision requirements. Reasonable flow rate adjustment can reduce unnecessary energy loss and improve the energy efficiency of the equipment.
[0030] Furthermore, the superimposed solenoid valve 5 of the present invention is also equipped with an explosion-proof solenoid valve 6. The explosion-proof solenoid valve 6 is used to control the movement of the valve core through electromagnetic force, thereby changing the flow path of the liquid in the hydraulic pipeline, so as to control the reversing or starting and stopping of the hydraulic power unit. The explosion-proof solenoid valve 6 of the present invention can quickly and accurately change the flow path of the liquid, realize the rapid reversing of the hydraulic power unit, and achieve safe starting and stopping of the hydraulic power unit by controlling the opening and closing of the explosion-proof solenoid valve 6.
[0031] Furthermore, a balance valve 7 is provided between the superimposed solenoid valve 5 and the hydraulic motor 2 of the present invention. The balance valve 7 is used to control the flow rate of the liquid in the hydraulic pipeline to a constant value when the machine is not in operation. The balance valve 7 of the present invention can lock the flow rate of the liquid in the hydraulic pipeline when the machine is not in operation, which prevents the turbofan gun from shaking or being damaged due to flow fluctuations when applied to turbofan guns, thereby improving the stability of the turbofan gun.
[0032] In some embodiments, the hydraulic pipeline of the present invention is further provided with a suction filter 8, which is installed near the oil tank 1 to filter the liquid entering the hydraulic pipeline. The suction filter 8 of the present invention can remove impurities and particulate matter from the liquid, preventing them from damaging the entire hydraulic system and the turbofan gun. Furthermore, the present invention provides a breather plug 9 at the top of the oil tank 1, which is used to balance the air pressure inside and outside the oil tank 1. Through the design of the breather plug 9, the present invention ensures that the air pressure inside and outside the oil tank 1 remains balanced, preventing liquid leakage or damage to the mechanism due to pressure differences.
[0033] The hydraulic power unit of this invention is further equipped with a pressure gauge 10 and a relief valve 11 in its hydraulic pipeline. The pressure gauge 10 is used to monitor the liquid pressure of the hydraulic power unit in real time, and the relief valve 11 is used to select whether to open or close based on the pressure value of the pressure gauge 10, thereby maintaining the working pressure of the hydraulic pipeline. The pressure gauge 10 of this invention can monitor the liquid pressure value in real time, ensuring that the hydraulic system operates within a safe range. The relief valve 11 can automatically open when the pressure exceeds a set value, releasing excess liquid pressure and preventing damage to the hydraulic system due to overpressure.
[0034] like Figure 2 As shown, the rotary unit of the present invention includes a rotary body 12. The output shaft of the hydraulic motor 2 is connected to the lower end of the rotary body 12, and the upper end of the rotary body 12 is provided at a connection position 13. The connection position 13 can connect to the structure to be rotated, such as the turbofan gun unit shown in the figure. The turbofan gun has a mounting base 14. The design of the rotary unit of the present invention makes the entire mechanism compact, easy to install and maintain, and the connection position can easily connect to the structure to be rotated, such as the turbofan gun part, to achieve fast and stable rotary motion.
[0035] This invention discloses an operating method for a hydraulically driven turbofan cannon rotary mechanism, comprising the following steps: checking and verifying the airtightness of each component in the turbofan cannon rotary mechanism; connecting the turbofan cannon rotary mechanism to an external power source; turning on the power; controlling the drive component of the hydraulic power unit through the control unit; the drive component delivers liquid to the hydraulic motor through hydraulic pipelines and controls the speed of the hydraulic motor, thereby driving the rotary unit to move; wherein, the hydraulic power unit achieves reversal or start / stop by changing the flow path of the liquid in the hydraulic pipelines; in the non-operating state, the controller maintains a constant liquid flow rate in the hydraulic pipelines. This invention, through precise control of the drive component by the control unit, can achieve precise adjustment and control of the rotary motion, thereby achieving precise positioning of the turbofan cannon and improving the stability of fire extinguishing.
[0036] 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.
