Description

Technical Field

[0001] The present invention relates to the technical field of icing test, and particularly relates to a temperature-controlled icing photoelastic test device and a method thereof. Background Technique

[0002] The icing phenomenon refers to the melting of the contact part of ice due to the increase in pressure under the action of pressure. When the external load is removed, the water at the contact surface recondenses into ice. At present, the main method for observing the icing phenomenon is the suspension method, which measures the time required for copper wires with different radii to pass through the ice block. This method has a large measurement error and is greatly affected by the operation of experimental personnel; moreover, it cannot effectively observe the stress distribution state of the ice block during the icing process, and cannot provide an experimental basis for the mechanism analysis of icing. In addition, after the detection is completed, there will be some moisture in the melted part on the surface of the test device. If these moisture are not quickly cleaned, it will not only affect the next test, but also cause damage to the test equipment. And due to the presence of moisture, the humidity of the test environment is relatively high, which greatly affects the accuracy of the test.

[0003] In view of the above problems, the present invention document proposes a temperature-controlled icing photoelastic test device and a method thereof. Summary of the Invention

[0018] A ball is fixed above the movable rod, and the ball contacts one end of a bent plate.

[0019] A method for using a temperature-controlled ice-recovering photoelastic test device includes the following steps:

[0020] S1. When performing an ice-recovering test, place the ice block on the lower clamp, and drive the rotation of the rotating shaft through an operation panel. The rotating shaft drives the transmission between the first bevel gear and the second bevel gear. The second bevel gear drives the rotation of the threaded cylinder. The threaded cylinder drives the stud to move downward. The stud drives the upper clamp to move downward. The upper clamp contacts the ice block downward, and the upper clamp applies a load to the ice block through pressure;

[0021] When the upper clamp moves downward, the upper clamp drives the adjusting plate to move downward, at this time, the first spring drives the toothed plate to reset downward, and the toothed plate is pre-transmitted with the second gear downward, and the second gear drives the crankshaft to rotate, so that the crankshaft drives the annular frame to move, and the annular frame drives the roller rod to move through the first sliding sleeve, so that the roller rod drives the first scraper to move, and at the same time, the first sliding sleeve also drives the second cleaning assembly to move. When the roller rod moves to the position of the inclined block and squeezes the roller rod to move through the inclined surface of the inclined block, the second spring is deformed, so that the height of the second scraper is lower than the upper height of the lower clamp. At the same time, the ball moves to the inclined surface of one end of the bent plate, and drives the third spring to deform through the inclined surface extrusion, so that the height of the second scraper is lifted and staggered with the upper clamp, and the toothed plate also drives the first gear downward, so that the first gear drives the two nuts away from each other through the screw rod, and drives the box body to the water outlet position through the connecting rod. At this time, dehumidification operation is performed through the hygroscopic material;

[0022] S3, then, natural light is emitted by the light source, passes through the polarizer, and then passes through the quarter glass slide to reach the temperature control box, and then passes through the quarter glass slide and then passes through the analyzer to be captured by the camera, so as to observe the stress distribution of ice during the re-icing process;

[0023] S4. After the test, the control operation disk is rotated in the reverse direction to make the upper clamp move upward. When the upper clamp pushes the toothed plate through the adjusting plate, the toothed plate is pre-transmitted with the first gear. The first gear drives the two nuts to move closer to each other through the screw rod, so that the connecting rod drives the box body to be recovered to the bottom of the lower clamp. Then the toothed plate is upwardly transmitted with the second gear, so that the crankshaft drives the annular frame to move, and the first sleeve drives the roller rod to separate from the inclined surface of the inclined block. At this time, the second spring drives the first scraper to reset upward, so that the first scraper corresponds to the lower clamp, and the first scraper moves along the lower clamp, so that the first scraper scrapes the crushed ice on the lower clamp to the water outlet and enters the water tank. At the same time, the first sleeve also drives the second sliding rod to move, so that the movable rod drives the ball to separate from the inclined surface of the bent plate. At this time, the third spring drives the second scraper to reset downward, so that the second scraper passes from the bottom of the upper clamp to scrape off the residual ice, so as to carry out the next round of re-icing test operation.

[0024] Compared with the prior art, the present invention provides a temperature-controlled re-icing photoelasticity test device and method thereof, which have the following beneficial effects:

[0025] 1. The temperature-controlled ice-recovery photoelastic test device and its method. The loading component lifts the transmission component, causing the transmission component to drive the second gear. The second gear drives the annular frame to move through the crankshaft. The annular frame drives the first sliding sleeve and the roller rod to move, causing the second spring to drive the first scraper to reset. The first scraper passes over the surface of the lower fixture. Meanwhile, the first sliding sleeve drives the second sliding rod to move, causing the third spring to drive the second scraper to reset. The second scraper passes under the upper fixture. The first scraper and the second scraper can clean the lower fixture and the upper fixture, reducing the residue of moisture and broken ice on the upper fixture and the lower fixture, thus facilitating the next round of test operations.

[0026] 2. The temperature-controlled ice-recovery photoelastic test device and its method. When the loading component moves downward, the first spring drives the toothed plate to reset downward. Then the toothed plate can be pre-driven by the second gear. The crankshaft drives the annular frame and the first sliding sleeve to move. The first sliding sleeve drives the first scraper to move through the roller rod. The first scraper can pass over the lower fixture again. At the same time, the first sliding sleeve also drives the second cleaning component to pass over the upper cleaning component again. The first scraper and the second scraper further clean the moisture, improving the cleaning effect. The water and broken ice after the initial cleaning and the secondary cleaning can enter the water tank through the water outlet for collection, avoiding polluting the test environment. After cleaning, the toothed plate drives the first gear downward, causing the screw rod to drive the two nuts to move away from each other. The connecting rod pushes the box body to move, making the box body correspond to the water outlet. At this time, the moisture-absorbing material is exposed, and then the moisture-absorbing material is used for dehumidification operation.

[0027] 3. The temperature-controlled ice-recovery photoelastic test device and its method. The loading component controls the movement of the transmission component, causing the transmission component to be pre-driven by the swing component. The first cleaning component disengages from the inclined surface of the inclined block. At this time, the first cleaning component corresponds to the lower fixture and moves to clean the moisture on the lower fixture. Meanwhile, the first cleaning component drives the second cleaning component to displace, enabling the second cleaning component to clean the moisture on the upper fixture. After cleaning, the toothed plate is driven by the adjustment component, and then the moisture-absorbing material can be adjusted to be at the position of the water outlet. Thus, by initially scraping off the moisture, the moisture residue is reduced, greatly enhancing the dehumidification effect of the moisture-absorbing material, reducing the test error, and achieving the purpose of automatic cleaning.

[0028] 4. The temperature-controlled ice-recovery photoelastic test device and its method. The natural light emitted by the light source passes through the polarizer, then passes through the quarter-wave plate and reaches the temperature control box. Subsequently, it passes through the quarter-wave plate again and is captured by the camera through the analyzer. In this way, the test operation is less affected by the outside world, and the test load can be accurately controlled. At the same time, the stress distribution of the ice during the ice-recovery process can be observed in real time. BRIEF DESCRIPTION OF THE DRAWINGS
