Description

Technical Field

[0001] The invention relates to the field of jet propulsion device test equipment, in particular to a jet propulsion device test platform. Background Art

[0002] In the field of ship engineering and marine equipment research and development, the research and testing of jet propulsion devices is of vital importance. With the continuous advancement of technology, the demand for accurate evaluation and optimization of jet propulsion device performance is becoming increasingly urgent, and more advanced and accurate test platforms are needed to support research and development work in order to adapt to the increasingly complex marine operating environment and high-efficiency ship design requirements.

[0003] At present, most of the test platforms for jet propulsion devices are relatively simple in structure design. In terms of fixing the propulsion device, there is a lack of convenient and stable installation methods, which affects the stability and test accuracy of the device. For data monitoring, most of them are focused on basic flow or pressure monitoring, and the monitoring method is single, which cannot fully and accurately reflect the actual working performance of the device and is difficult to meet the needs of high-precision research and development.

[0004] Generally, the propulsion device is placed directly in a specific area of ​​the test platform and connected to the power source through a simple mechanical connection, such as connecting the motor to the shaft of the propulsion device. During the test, a simple flow meter is used to measure the flow at the outlet, and a pressure gauge is used to measure the pressure at a specific location. After data collection, a simple analysis is performed, lacking a systematic calibration and in-depth performance analysis process.

[0005] The prior art lacks the precise calibration device of the present invention, making it difficult to accurately calibrate the operating parameters of the propulsion device, resulting in large errors in the test data. The pressure sensing device is not perfect enough to fully and accurately measure the water flow thrust, and it is impossible to deeply explore the working characteristics of the propulsion device. At the same time, there is a lack of effective internal circulation design, and the liquid supply is unstable, which affects the continuity and accuracy of the test. Summary of the invention

[0012] With such an arrangement, the hydraulic cylinder controls the liquid storage cylinder to move up and down, thereby providing liquid supply to the propulsion device.

[0013] The present invention is further configured such that a first connection port is provided at the bottom of the hydraulic cylinder, a second connection port is provided at the bottom of the water storage tank, and the first connection port and the second connection port are connected via a pipeline.

[0014] With such an arrangement, the water stored in the water outlet tank is supplied to the liquid storage cylinder through the first connection port and the second connection port, thereby providing liquid supply for the propulsion device.

[0015] The present invention is further configured such that a driving device is provided at one end of the device body away from the water tank in cooperation with the propulsion device, and the driving device includes a fixed block, a stepper motor is provided on the fixed block, the stepper motor is connected to a first transmission shaft, the first transmission shaft extends into the mounting groove, passes through the propulsion device, and is connected to a turbine fan inside the propulsion device.

[0016] Through such an arrangement, the first transmission shaft is driven by the stepper motor, thereby driving the turbine fan to rotate, thereby achieving the suction and discharge of liquid.

After the water flows through the propulsion device, it is forcefully ejected from one end of the second connecting plate. At the same time, the rotating water outlet valve of the calibration device rotates under the action of the water flow and links the counter to record data, thereby effectively driving the propulsion device to operate stably. With the help of the calibration device, the coordinated analysis of the stepper motor rotation number and the counter data can be used to accurately calibrate various parameters of the device, which greatly improves the accuracy and reliability of the propulsion device measurement and provides a strong guarantee for subsequent operations.

[0023] 2. The hydraulic cylinder of the present invention accurately controls the liquid storage cylinder to move up and down in the slot according to demand, so that it is connected to the water storage tank through a pipeline to realize liquid transmission. When the water outlet of the calibration device sprays water, the water flow and the top plate of the pressure sensing device form a reverse thrust, which drives the rotating water outlet valve to rotate and squeeze the top plate. The pressure sensor records the thrust data, cleverly achieving internal circulation of the liquid, creating good conditions for the continuous and stable operation of the propulsion device. The pressure sensing device records the thrust in real time, which helps to deeply analyze the working performance of the propulsion device and accurately grasp its parameter changes under different working conditions, so as to make timely adjustments and optimizations to improve the overall working efficiency.
