Description

Technical Field

[0001] This invention relates to the field of experimental auxiliary devices, and in particular to a fluid mechanics experimental auxiliary device and its usage method. Background Technology

[0002] Fluid mechanics is a core discipline that studies the velocity, pressure, drag, lift, vortex, and energy changes of fluids such as water, air, oil, and flue gas when they are at rest and in motion. It is widely used in fields such as hydraulic engineering, mechanical manufacturing, aerospace, and chemical production. Measured fluid data, observed flow phenomena, verified theoretical simulations, and obtained engineering parameters all rely on experiments, and the performance of the experimental apparatus directly determines the accuracy of the experimental data and the efficiency of the experiment.

[0003] Current traditional fluid mechanics experimental setups suffer from several drawbacks. First, the fluid supply is unstable, often employing non-constant pressure, non-circulating fluid supply structures. This makes precise control of fluid velocity, flow rate, and pressure impossible, leading to significant fluctuations in fluid state and substantial deviations in experimental data. Second, sampling and detection efficiency is low, relying on manual fixed-point sampling. The sampling location and height are not flexibly adjustable, making it impossible to obtain samples from different points and depths within the fluid channel. Furthermore, the sampling containers have poor compatibility, and the detection process is cumbersome. Third, simulation acquisition accuracy is poor. The experimental simulation components have fixed structures, and the simulation data acquisition blocks cannot be flexibly raised, lowered, or moved, making it difficult to comprehensively collect simulation experimental data and resulting in insufficient data integrity. Fourth, fluid mechanics experimental auxiliary devices lack versatility, lacking movable structures, making device transport inconvenient and limiting their adaptability to various experimental scenarios. Fifth, the absence of a fluid filtration and recovery system prevents the recycling of experimental fluids, leading to resource waste. Sixth, the experimental process is fragmented, failing to form an integrated process for fluid flow, monitoring, extraction, detection, and simulation. The disconnect between different stages results in complex operation, high error rates, and severely restricts experimental efficiency.

[0004] To address the aforementioned problems, a fluid mechanics experimental auxiliary device and its usage method are proposed. Summary of the Invention

The gears 905 then drive the drive rod 906 to rotate, realizing the horizontal displacement adjustment of the simulation data acquisition block 913. The meshing transmission structure has high transmission efficiency and high displacement accuracy, without slippage or jamming, making the displacement of the simulation component 9 precise and controllable. It solves the problems of fixed displacement and limited acquisition range of traditional simulation devices. Combined with the lifting structure, it realizes full-dimensional data acquisition and improves the comprehensiveness of experimental simulation.

[0032] Both fixed plates 904 are fixedly connected to the top left center of the simulation box 15, and the bottom of the movable plate 910 is attached to the top of the simulation data acquisition block 913. This design is to simulate the fixed and attached structure of component 9. The fixed plates 904 are symmetrically fixed to the top left center of the simulation box 15 to provide a stable installation base for gear 905 and rack 903, avoid loosening and displacement of components during transmission, and strengthen the connection stability of components, eliminate data acquisition errors, ensure the integrity and reliability of simulation experimental data, and improve the accuracy of experimental results.

Simulation data acquisition block 913 collects experimental data. After the experiment, the fluid in simulation chamber 15 is discharged through discharge pipe 17. This design is to move and fix the mounting plate 1 to the experimental position using the moving wheels 2. 2. Start the circulating fluid supply system 304 and circulating water pump 309, and adjust the regulating valve 306 to set the fluid parameters so that the fluid flows stably in flow chamber 1 307 and flow chamber 2 308. 3. Drive the slider 502 to slide along the slide rail 501, and the motor 504 drives the moving plate 1 505 to rise and fall. The collection head 507 collects samples and injects them into the collection tube 603. 4. Start the electric push rod 1 702 to drive the probe head 706 to position, and the detection component 8 completes the fluid parameter detection. 5. The extraction mechanism 12 extracts the fluid through the connecting pipe 2 11, and the release head 13 delivers it to the simulation chamber 15. The filter plate 16 filters the fluid, and the return water pipe 18 returns the fluid. 6. Start the electric push rod 2 902 and electric push rod 3 909, and the simulation data acquisition block 913 collects data. After the experiment, the fluid is discharged through discharge pipe 17. This process covers all aspects of the experiment, and the integrated operation improves experimental efficiency and ensures the accuracy of data in fluid mechanics experiments.

[0034] Working principle: Before starting the fluid mechanics experiment auxiliary device, the operator uses the movable wheels 2 to push the mounting plate 1 to the designated experimental position, thus completing the positioning and fixing of the entire fluid mechanics experiment auxiliary device. The flexible movement characteristics of the movable wheels 2 solve the problems of inconvenient handling and poor scene adaptability of traditional fluid mechanics experiment auxiliary devices, providing a stable working foundation for subsequent experiments. The mounting plate 1, as the core load-bearing component, supports the entire structure, including the flow channel assembly 3, the connecting plate 1 4, and the simulation box 15, ensuring the overall stability of the fluid mechanics experiment auxiliary device during operation and preventing component shaking from affecting the accuracy of experimental data.

[0035] In the fluid supply stage, the flow channel component 3 enters the working state, activating the circulating fluid supply system 304 and the circulating water pump 309. The high-level constant-pressure overflow tank 303 provides constant water pressure, eliminating experimental errors caused by fluid pressure fluctuations. The operator adjusts the regulating valve 306 to precisely control the fluid velocity, flow rate, and pressure, enabling the fluid to form a stable circulating flow field within the first flow chamber 307 and the second flow chamber 308. The connecting pipe 305 ensures the orderly delivery of fluid within the system. This circulating constant-pressure supply structure solves the problems of unstable fluid supply and low parameter control accuracy in traditional fluid mechanics experimental auxiliary devices from the source, providing a standardized fluid environment for experiments.

[0036] In the fluid sampling process, the collection component 5 starts operating, and the slider 502 slides horizontally along the slide rail 501, driving the connecting block 503 and the motor 504 to move to the designated sampling point. The motor 504 drives the moving plate 505 to rise and fall along the limiting rod 506, adjusting the collection head 507 to the target depth of the fluid channel. The collection head 507 automatically extracts the fluid sample and directly injects it into the collection tube 603 of the collection component 6. The clamping plate 602 on the placement rack 601 stably holds the collection tube 603, which can simultaneously accommodate multiple specifications and batches of samples, avoiding positional deviations and sample contamination problems caused by manual sampling, achieving accurate sampling at all points and depths, and improving sampling efficiency and sample integrity.

[0037] In the fluid detection stage, the adjustment component 7 and the detection component 8 work together. The electric push rod 702 pushes the fixed plate 703 and the connecting frame 704 to rise and fall. The moving block 708 drives the T-block 709 to slide along the limit block 707, ensuring that the probe head 706 is smoothly moved to the detection point. The hose 705 adapts to the rising and falling displacement of the probe head 706 and collects fluid status signals in real time. The detection tube 803 is fixed to the connecting frame 801 by the clamp 802. The fluid flows into the detector 804 through the detection tube 803. The placement tube 806 assists in fluid guidance and quickly completes the fluid parameter detection. The probe head 706 and the detector 804 work together to realize the integration of real-time monitoring, accurate detection and flexible adjustment of fluid status, simplifying the detection process and improving detection efficiency.

[0038] In the fluid simulation stage, the extraction mechanism 12 extracts the experimental fluid from the flow channel through the connecting pipe 11 and delivers it to the simulation chamber 15 through the release head 13. The simulation chamber 15 provides a closed space for the fluid simulation experiment. The filter plate 16 filters and purifies the impurities in the fluid, improving the purity of the simulated experimental fluid. The return water pipe 18 returns the filtered fluid to the flow channel assembly 3, realizing fluid recycling. The discharge pipe 17 is used to discharge the remaining fluid in the simulation chamber 15 after the experiment. The recycling structure greatly reduces fluid consumption and meets the requirements of environmental protection and energy saving in experiments.

[0039] In the simulated data acquisition stage, the simulation component 9 operates at full power. The electric push rod 902 drives the rack 903 to move linearly. The rack 903 meshes with the gear 905, driving the drive rod 906 to rotate along the connecting seat 907, thereby realizing the horizontal displacement of the simulated data acquisition block 913. The electric push rod 909 drives the moving plate 910 to rise and fall along the limiting rod 911, adjusting the height of the simulated data acquisition block 913. The fixed block 901 and the fixed plate 904 provide rigid support for the transmission structure, ensuring accurate and deviation-free displacement. The simulated data acquisition block 913 collects data such as flow rate, pressure, and resistance from all directions in the simulation experiment. The moving plate 910 fits tightly with the simulated data acquisition block 913, eliminating data acquisition errors and improving the completeness and accuracy of the experimental data.

[0040] Throughout the entire experimental process, experimental board 10 provides a carrier for fluid flow observation, while connecting board 4 and connecting board 14 ensure a stable connection. They work together in an orderly manner according to the preset process to form an integrated experimental system for fluid flow, monitoring, extraction, detection, simulation, and data acquisition. This solves the problems of unstable supply, inefficient sampling, poor simulation accuracy, fragmented process, and waste of resources in traditional fluid mechanics experimental devices. Through structured linkage and automated control, it significantly improves experimental efficiency, data accuracy, and the versatility of fluid mechanics experimental auxiliary devices, meeting the practical needs of fluid mechanics experiments in multiple fields such as water conservancy, machinery, and aviation.
