Description

Technical Field

[0001] This invention relates to the field of mechanical devices, specifically to an angle-adjustable turbofan gun and its usage method. Background Technology

[0002] In the field of marine firefighting, efficient and precise firefighting equipment is crucial. With the continuous development of the marine economy and the increasing frequency of maritime activities, the requirements for marine firefighting capabilities are also constantly increasing.

[0003] Currently, traditional marine firefighting equipment has many shortcomings in terms of horizontal rotation and pitch angle adjustment. Many marine turbofan fire monitors lack flexibility in angle adjustment, making it difficult to quickly and accurately target the fire source. In the complex marine environment, the location of the fire source may constantly change due to factors such as waves and wind direction, requiring the turbofan fire monitor to be able to quickly adjust its angle to cope with different situations.

[0004] The existing marine fire-fighting turbofan cannons also need improvement in terms of the accuracy and stability of angle adjustment. During firefighting, if the angle adjustment is inaccurate or unstable, it may lead to poor firefighting effect, or even miss the best time to extinguish the fire, allowing the fire to spread further.

[0005] Furthermore, traditional marine fire-fighting turbofan monitors also have operational limitations. The complex angle adjustment methods increase the difficulty and time cost for operators, reducing fire-fighting efficiency. Moreover, in emergency situations, rapid and accurate angle adjustments are crucial for ensuring the safety of life and property.

[0006] In summary, in order to meet the actual needs of marine firefighting and improve marine firefighting capabilities, an angle-adjustable turbofan cannon and its usage method are provided. Summary of the Invention

[0007] The purpose of this invention is to provide an angle-adjustable turbofan gun and its usage method, so as to overcome the shortcomings of the prior art in terms of low angle adjustment accuracy, weak stability and complicated operation.

[0008] To achieve the above objectives, the present invention provides the following technical solution: On one hand, this invention provides an angle-adjustable turbofan gun, comprising a turbofan gun body, a horizontal position adjustment device, and a pitch position adjustment device. The turbofan gun body is connected to the horizontal position adjustment device, and the turbofan gun body is connected to the pitch position adjustment device. The horizontal position adjustment device is connected to a hydraulic power unit, and the hydraulic power unit is also connected to the pitch position adjustment device. The horizontal position adjustment device is used to adjust the horizontal position angle of the turbofan gun, and the pitch position adjustment device is used to adjust the pitch position angle of the turbofan gun. The hydraulic power unit provides power output to both the horizontal and pitch position adjustment devices. The hydraulic power unit connects to both adjustment devices simultaneously, achieving centralized power supply and unified management, and reducing system complexity.

[0009] Furthermore, the horizontal position adjustment device includes an encoder, a proximity switch, and a rotary motor; the encoder is connected to the rotary motor, proximity switches are installed on both sides of the rotary motor, and the rotary motor is connected to a hydraulic power unit.

[0010] Furthermore, the encoder is an absolute encoder, and the proximity switch is a non-contact Hall effect proximity switch. Using an absolute encoder allows for precise recording of position information, ensuring accurate angle adjustment. The non-contact Hall effect proximity switch further improves the accuracy and stability of position detection, avoiding wear and errors that may occur with contact switches.

[0011] Furthermore, the pitch position adjustment device includes an encoder, a proximity switch, and two hydraulic cylinders. Each hydraulic cylinder is connected to a piston rod. The encoder is connected to the piston rod and can provide real-time feedback on the extension and retraction length of the hydraulic cylinder, thereby accurately controlling the pitch angle. The two hydraulic cylinders are connected, and proximity switches are installed at the top and bottom of the two hydraulic cylinders, further improving the accuracy and safety of the pitch angle adjustment. The two hydraulic cylinders are connected to a hydraulic power unit.

[0012] Furthermore, the hydraulic power unit includes an oil tank and an explosion-proof motor; the oil tank is connected to an oil suction filter, the oil suction filter is connected to a gear pump, the gear pump is connected to the explosion-proof motor, the gear pump is connected to a first explosion-proof solenoid valve and a second explosion-proof solenoid valve, the first explosion-proof solenoid valve is connected to a first stacked throttle valve, the first stacked throttle valve is connected to a first balance valve, and the first balance valve is connected to a pitch position adjustment device; the second explosion-proof solenoid valve is connected to a second stacked throttle valve, the second stacked throttle valve is connected to a second balance valve, and the second balance valve is connected to a horizontal position adjustment device.

[0013] Furthermore, the gear pump is connected to a pressure gauge, and an overflow valve is connected between the gear pump and the oil tank. A breather plug is installed on the oil tank. The pressure gauge can monitor the system pressure in real time, allowing operators to adjust operations promptly based on pressure conditions, preventing damage to the equipment caused by excessively high or low system pressure. The overflow valve automatically releases pressure when the system pressure exceeds a safe value, protecting the entire hydraulic system. The breather plug on the oil tank ensures pressure balance between the tank and the external environment, preventing damage to the tank due to pressure changes and improving equipment reliability.

[0014] Furthermore, the horizontal rotation angle of the horizontal position adjustment device is 360 degrees, which allows the turbofan gun to aim at the target without blind spots, greatly improving its applicability in different scenarios.

[0015] Furthermore, the pitch position adjustment device has an elevation angle of not less than 45° and a depression angle of not less than 30°, which can meet the processing needs of targets at different heights. It can accurately locate targets whether dealing with fire sources at high altitudes or dangerous areas at low altitudes.

[0016] Furthermore, the hydraulic power unit has a power of 1500W, a pressure of 8MPa, and a flow rate of 4.5L / min. The hydraulic power unit provides stable power output for the entire system, ensuring sufficient power to drive the turbofan gun to adjust its angle under various complex working conditions.

[0017] Furthermore, the present invention also provides a method for using an angle-adjustable turbofan gun, the specific steps of which are: the hydraulic power unit provides power to the horizontal position adjustment device and the pitch position adjustment device, driving the horizontal position adjustment device to perform horizontal rotation and pitch angle adjustment.

[0018] Compared with the prior art, the present invention has the following beneficial technical effects: This invention provides an angle-adjustable turbofan gun and its usage method. Through the coordinated action of a horizontal position adjustment device and a pitch position adjustment device, the turbofan gun can achieve omnidirectional angle adjustment. An absolute encoder is employed to accurately record position information, ensuring the accuracy of angle adjustment. A non-contact Hall effect proximity switch further improves the accuracy and stability of position detection, avoiding wear and errors that may occur with contact switches. This allows the turbofan gun to aim at targets without blind spots, greatly improving its applicability in various scenarios. The pitch position adjustment device can meet the needs of handling targets at different heights, accurately locating targets whether dealing with high-altitude fire sources or low-altitude dangerous areas. A hydraulic power unit provides stable power output to both the horizontal and pitch position adjustment devices, ensuring sufficient power to drive the turbofan gun for angle adjustment under various complex working conditions. The usage method of the turbofan gun provided by this invention is simple and clear: the hydraulic power unit provides power to the horizontal and pitch position adjustment devices, driving them to perform horizontal rotation and pitch angle adjustment. Operators can adjust the angle of the turbofan gun simply by controlling the output of the hydraulic power unit through the control system, which greatly improves the convenience of operation and work efficiency.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0025] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0026] Example 1 See Figures 1 to 4 An angle-adjustable turbofan gun includes a main body, a horizontal position adjustment device, and a vertical position adjustment device. The main body is connected to both the horizontal and vertical position adjustment devices. The horizontal position adjustment device is connected to a hydraulic power unit, which in turn is connected to the vertical position adjustment device. The hydraulic power unit provides power to both devices. The main body's connection to both devices allows for more direct and effective angle adjustment. The hydraulic power unit's simultaneous connection to both devices enables centralized power supply and management, reducing system complexity. The horizontal position adjustment device has a horizontal rotation angle of 360°, the vertical position adjustment device has an elevation angle of not less than 45° and a depression angle of not less than 30°, and the hydraulic power unit has a power of 1500W, a pressure of 8MPa, and a flow rate of 4.5L / min.

[0027] The horizontal position adjustment device includes an encoder, a proximity switch, and a rotary motor 10. The encoder is connected to the rotary motor 10, and proximity switches are installed on both sides of the rotary motor 10. The rotary motor 10 is connected to a hydraulic power unit. The encoder is an absolute encoder, and the proximity switches are non-contact Hall effect proximity switches. The absolute encoder accurately measures the rotation angle of the rotary mechanism, i.e., the horizontal position of the turbofan gun body. When the rotary mechanism (driving the turbofan gun body) rotates into the sensing range of the proximity switch, the proximity switch will sense it, thus determining the approximate position of the turbofan gun. It can also be used to prevent the rotary mechanism from over-rotating.

[0028] The pitch position adjustment device includes an encoder, a proximity switch, and two hydraulic cylinders 9. Each hydraulic cylinder 9 is connected to a piston rod. The encoder is connected to the piston rod. The two hydraulic cylinders 9 are connected, and proximity switches are installed at both the top and bottom of each cylinder. The two cylinders 9 are connected to a hydraulic power unit. The encoder is an absolute encoder, and the proximity switches are non-contact Hall effect proximity switches. The absolute encoder's main function is to accurately measure the change in the extension / retraction length of the hydraulic cylinder, thereby indirectly determining the position of the turbofan gun body in the pitch direction. The non-contact Hall effect sensor monitors the specific position of the hydraulic cylinder's movement. When the hydraulic cylinder extends or retracts to the point where the turbofan gun body reaches the sensing area of ​​the proximity switch, the proximity switch will detect the movement, determining the approximate position of the turbofan gun and preventing it from exceeding the safe range or causing equipment damage. The hydraulic cylinders 9 are connected to the hydraulic power unit via hydraulic lines and extend or retract synchronously or in coordination under the drive of the hydraulic power unit. When it is necessary to adjust the pitch angle of the turbofan gun, the hydraulic power unit supplies hydraulic oil to the hydraulic cylinders 9, causing the piston rods of the cylinders 9 to extend or retract, thereby moving the turbofan gun body in the pitch direction. The encoder and proximity switch indirectly control the pitch position of the turbofan gun by monitoring the motion state of the hydraulic cylinder 9, ensuring that the pitch angle adjustment is accurate, stable and within a safe range.

[0029] The hydraulic power unit includes an oil tank 1 and an explosion-proof motor 3. The oil tank 1 serves as a storage container for hydraulic oil, providing a sufficient oil source for the entire hydraulic power unit. The oil tank 1 is connected to a suction filter 2, which is connected to a gear pump 4. The suction filter 2, located between the oil tank 1 and the gear pump 4, effectively filters impurities in the hydraulic oil, preventing them from entering the gears 4 and other hydraulic components. This avoids wear and malfunctions caused by impurities, extending the service life of the hydraulic power unit. The gear pump 4 is connected to the explosion-proof motor 3, which provides power to the gear pump 4, ensuring the hydraulic oil's stability. For the normal operation of the hydraulic power unit, the gear pump 4 is connected to a first explosion-proof solenoid valve 6-1 and a second explosion-proof solenoid valve 6-2, which can precisely control the flow of hydraulic oil. The first explosion-proof solenoid valve 6-1 is connected to a first stacked throttle valve 7-1, which is connected to a first balance valve 8-1, which is connected to a pitch position adjustment device. The second explosion-proof solenoid valve 6-2 is connected to a second stacked throttle valve 7-2, which is connected to a second balance valve 8-2, which is connected to a horizontal position adjustment device. The rapid response characteristics of the solenoid valves enable the hydraulic power unit to quickly switch working states, achieving rapid adjustment of the horizontal and pitch positions of the turbofan gun. The stacked throttle valves are compact in design, easy to install, and can be well integrated with other hydraulic components. The balance valves can automatically adjust the flow of hydraulic oil when the cylinders and hydraulic motors are working, ensuring smooth movement. The various components of the hydraulic power unit work together to provide stable power and precise control for the horizontal and pitch position adjustment devices of the turbofan gun. The explosion-proof motor 3 drives the gear pump 4 to deliver hydraulic oil to various hydraulic components. Then, through the precise control of the solenoid valve, throttle valve and balance valve, the speed and direction of the oil cylinder 9 and the rotary motor 10 are controlled.

[0030] Example 2 This invention also provides a method for using an angle-adjustable turbofan gun. The hydraulic power unit provides power to the horizontal position adjustment device and the pitch position adjustment device, driving the horizontal position adjustment device to perform horizontal rotation and pitch angle adjustment. The hydraulic power unit drives the rotary motor 10 to rotate, causing the turbofan gun body to rotate horizontally. An absolute encoder provides real-time feedback of horizontal position information, and a proximity switch triggers a signal at a specific position to assist the horizontal position adjustment device in achieving precise horizontal angle adjustment. When the operator issues a pitch angle adjustment command, the hydraulic power unit drives two cylinders to extend and retract, causing the turbofan gun body to pitch. The absolute encoder and proximity switch also play a role in the pitch position adjustment process, ensuring the accuracy of the pitch angle.

[0031] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made on the basis of the technical solution of the present invention should be included within the scope of protection of the present invention.
