An anti-vortex auxiliary component for testing water-repellent properties

Abstract

This application provides an anti-vortex auxiliary component for testing water repellency, belonging to the field of fabric testing technology. The anti-vortex auxiliary component includes a water tank, inside which is an adjustment mechanism for adjusting the dripping position. The water tank also contains a moving mechanism that directs water from a spray device into a first water pipe, then through a connector into a drip head, from which water drips out. The drip head is movable along a track, allowing adjustment of the dripping position. This design prevents kinetic energy from being injected near the impact point with each drop, propelling the water flow outwards. Adjusting the dripping position reduces the probability of vortex formation. The ability of the drip head to move up and down brings it closer to the fabric, reducing the impact force and further decreasing the probability of vortex formation.

Description

Technical Field

[0001] This application relates to the field of fabric testing, and more specifically, to an anti-vortex auxiliary component for testing water repellency. Background Technology

[0002] The fabric water repellency test, also known as the water repellency (W / R) test, is designed to assess a fabric’s ability to resist water droplet penetration. This test mainly simulates everyday light water spray scenarios, such as light rain or splashes, rather than continuous heavy rain or soaking. The test principle is to form a hydrophobic layer on the fiber surface through chemical additives, causing water droplets to form beads and roll off the fabric instead of penetrating.

[0003] In existing technologies, the spray method is mainly used for water repellency testing. During the test, 250 mL of distilled water is sprayed from a 45° angle onto a 180 mm × 180 mm sample. The state of the water droplets and the wetted area are observed. Then, the level is evaluated by comparing with the standard picture. The water repellency level (0-5) is evaluated by comparing with the standard picture, with 5 indicating no wetting and 0 indicating complete wetting.

[0004] However, the existing water-repellent testing spray devices still have the following shortcomings during use: when water droplets hit the fabric surface with a certain impact force, the existing spray devices do not completely bounce off or spread into a water film, but instead form a short-lived, rapidly rotating small vortex on the fabric surface. This is easily confused with real water seepage / wetting, and testers may misjudge that the fabric has failed, when in fact it may be a hydrodynamic phenomenon caused by the impact force rather than insufficient surface energy of the fabric. Utility Model Content

[0005] To overcome the above shortcomings, this application provides an anti-vortex auxiliary component for testing water repellency, which aims to improve the formation of short-lived, rapidly rotating small vortices on the fabric surface by water droplets. These vortices are easily confused with actual water seepage / wetting, and testers may misjudge that the fabric has failed. In reality, this may be a hydrodynamic phenomenon caused by the impact force, rather than a problem of insufficient surface energy of the fabric.

[0006] This application provides an anti-vortex auxiliary component for testing water splash resistance, including a water tank, a spray device inside the water tank, an adjustment mechanism for adjusting the dripping position inside the water tank, and a moving mechanism inside the water tank.

[0007] The adjustment mechanism includes a first circular plate, which is disposed on one side of the spray device. Two sets of mounting brackets are connected to the bottom of the first circular plate, and a motor is connected between the two sets of mounting brackets. The output shaft of the motor is connected to a second circular plate.

[0008] In one specific implementation, the top of the second circular plate has multiple sets of sliding grooves, and vertical rods are slidably connected inside the sliding grooves.

[0009] In the above implementation process, by setting the sliding groove, when the motor controls the second circular plate to rotate, the vertical rod can be driven to slide inside the sliding groove.

[0010] In one specific implementation, the top of the first circular plate is connected to multiple sets of moving tracks, and the inside of the moving tracks is slidably connected to a slider, with the other end of the vertical rod connected to the outer surface of the slider.

[0011] In the above implementation process, by setting up a moving track, when the vertical rod moves, the sliding member can be driven to move inside the moving track. The sliding member is restricted by the moving track, so that the vertical rod can only move in the track direction of the moving track, which can adjust the position when the water droplets fall.

[0012] In one specific implementation, the moving mechanism includes a second water pipe connected to the output end of the spray device, and a slider is slidably connected inside the second water pipe.

[0013] In the above implementation process, by setting up the second water pipe, water in the spray device can flow into the interior of the second water pipe, and the slider can slide inside the second water pipe.

[0014] In one specific implementation, the bottom of the slider is connected to a third water pipe, one end of which passes through the bottom of the second water pipe and is rotatably connected to the top of the second circular plate.

[0015] In the above implementation process, by setting up a third water pipe, the third water pipe can extend and retract inside the second water pipe to adjust the height of the water droplets, and the slider can prevent the third water pipe from detaching from the inside of the second water pipe.

[0016] In one specific implementation, a fastener is connected to the outer surface of the second water pipe, and a bolt is threaded into one side of the fastener, with one end of the bolt penetrating the outer surface of the second water pipe.

[0017] In the above implementation process, by setting bolts, one end of the bolt is tightly attached to the outer surface of the third water pipe, fixing the third water pipe inside the second water pipe. When the inspector fixes the fabric on the outer surface of the spray device, the third water pipe can be moved into the second water pipe and fixed by bolts, which facilitates the fixing of the fabric.

[0018] In one specific implementation, the other end of the bolt is connected to an adjustment knob.

[0019] In the above implementation process, by adjusting the knob settings, the bolt can be rotated by turning the adjustment knob.

[0020] In one specific implementation, the outer surface of the second water pipe is connected to multiple sets of first water pipes, and the other end of the first water pipe is connected to a connector. The connector is connected to the bottom of the vertical rod, and the other end of the connector is connected to a drip head.

[0021] In the above implementation process, by setting up the first water pipe, the water flowing out of the spray device can flow into the interior of the first water pipe through the second and third water pipes, and then enter the interior of the drip head through the connector, and drip out from the output end of the drip head. The drip head can move in the direction of the moving track, and the position of the water droplet can be adjusted. If the water droplet keeps dripping in one position, it is easy to cause kinetic energy to be injected near the impact point with each impact, pushing the water flow to spread in all directions. Therefore, adjusting the position of the water droplet reduces the probability of eddy formation. By allowing the drip head to move up and down, the drip head can be brought closer to the fabric when dripping, which can reduce the impact force generated when the water droplet falls, and further reduce the probability of eddy formation.

[0022] In one specific implementation, a camera is connected inside the water tank, and a display screen is connected to the top of the water tank, with the camera and the display screen being electrically connected.

[0023] In the above implementation process, by setting up a camera, when the dripping head is close to the fabric, it is not convenient for people to directly observe the state of the water droplets on the fabric with their eyes. The camera records the state of the water droplets falling on the fabric and observes it on the display screen.

[0024] In one specific implementation, the first circular plate is connected to the outer surface of the second water pipe.

[0025] In the above implementation process, by setting the first circular plate, the first circular plate can remain stationary when the motor drives the second circular plate to rotate.

[0026] Compared with the prior art, the beneficial effects of this application are as follows: By setting the adjustment mechanism and the moving mechanism, the water flowing out of the spray device can flow into the interior of the first water pipe through the second and third water pipes, and then enter the interior of the drip head through the connector, and drip out from the output end of the drip head. The drip head can move in the direction of the moving track, which can adjust the position of the water droplet when it falls. If the water droplet continues to drip in one position, it is easy to cause kinetic energy to be injected near the impact point with each impact, pushing the water flow to spread in all directions. Therefore, adjusting the position of the water droplet when it falls reduces the probability of eddy formation. By allowing the drip head to move up and down, the drip head can be closer to the fabric when dripping, which can reduce the impact force generated when the water droplet falls, and further reduce the probability of eddy formation. This solves the problem of water droplets forming short-lived, rapidly rotating small vortices on the fabric surface, which can be easily confused with real water seepage / wetting. Testers may misjudge that the fabric has failed, when in fact it may be a hydrodynamic phenomenon caused by the impact force, rather than a problem of insufficient surface energy of the fabric.

[0038] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0039] Please see Figure 1 This application provides an anti-vortex auxiliary component for measuring water splash resistance, including a water tank 1.

[0040] Please see Figure 1 , Figure 2 and Figure 3 The water tank 1 is equipped with a spray device 4, an adjustment mechanism 2 for adjusting the dripping position, and a moving mechanism 3. The spray device 4 is existing technology and will not be described in detail here.

[0041] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The adjusting mechanism 2 includes a first circular plate 201, which is disposed on one side of the spraying device 4. Two sets of mounting brackets 203 are connected to the bottom of the first circular plate 201, and a motor 202 is connected between the two sets of mounting brackets 203. The output shaft of the motor 202 is connected to a second circular plate 204.

[0042] In a specific configuration, multiple sets of sliding grooves 207 are provided through the top of the second circular plate 204. A vertical rod 208 is slidably connected inside the sliding groove 207. Through the setting of the sliding groove 207, when the motor 202 controls the second circular plate 204 to rotate, the vertical rod 208 can be driven to slide inside the sliding groove 207.

[0043] In a specific configuration, the top of the first circular plate 201 is connected to multiple sets of moving tracks 2010. A slider 209 is slidably connected inside the moving track 2010. The other end of the vertical rod 208 is connected to the outer surface of the slider 209. By setting the moving track 2010, when the vertical rod 208 moves, it can drive the slider 209 to move inside the moving track 2010. The slider 209 is restricted by the moving track 2010, so that the vertical rod 208 can only move in the track direction of the moving track 2010, which can adjust the position of the water droplets.

[0044] In a specific configuration, the moving mechanism 3 includes a second water pipe 303, which is connected to the output end of the spray device 4. A slider 305 is slidably connected inside the second water pipe 303. Through the configuration of the second water pipe 303, water from the spray device 4 can flow into the interior of the second water pipe 303, and the slider 305 can slide inside the second water pipe 303.

[0045] In a specific configuration, the bottom of the slider 305 is connected to a third water pipe 304. One end of the third water pipe 304 passes through the bottom of the second water pipe 303, and the other end of the third water pipe 304 is rotatably connected to the top of the second circular plate 204. The third water pipe 304 allows the third water pipe 304 to extend and retract inside the second water pipe 303, adjusting the height of the water droplets. The slider 305 also prevents the third water pipe 304 from detaching from the inside of the second water pipe 303.

[0046] In the specific setup, a fastener 306 is connected to the outer surface of the second water pipe 303. A bolt 307 is threaded into one side of the fastener 306. One end of the bolt 307 passes through the outer surface of the second water pipe 303. With the bolt 307, one end of the bolt 307 is in close contact with the outer surface of the third water pipe 304, fixing the third water pipe 304 inside the second water pipe 303. This allows the third water pipe 304 to move into the second water pipe 303 and be fixed by the bolt 307 when the inspector fixes the fabric to the outer surface of the spray device 4, facilitating the fixation of the fabric.

[0047] In a specific configuration, the other end of the bolt 307 is connected to an adjustment knob 308. By adjusting the knob 308, the bolt 307 can be rotated.

[0048] In a specific configuration, the outer surface of the second water pipe 303 is connected to multiple sets of first water pipes 206. The other end of each first water pipe 206 is connected to a connector 205, which is attached to the bottom of the vertical rod 208. The other end of the connector 205 is connected to a drip head 2011. Through the first water pipe 206, water flowing from the spray device 4 passes through the second water pipe 303 and the third water pipe 304, flows into the interior of the first water pipe 206, and then through the connector 205 into the interior of the drip head 2011. The output end of 11 drips water, and the drip head 2011 can move in the direction of the moving track 2010, which can adjust the position of the water droplet when it falls. If the water droplet continues to drip in one position, it is easy to cause kinetic energy to be injected near the impact point with each impact, pushing the water flow to spread in all directions. Therefore, adjusting the position of the water droplet when it falls reduces the probability of eddy formation. By moving the drip head 2011 up and down, the drip head 2011 can be made closer to the fabric when dripping water, which can reduce the impact force generated when the water droplet falls, and further reduce the probability of eddy formation.

[0049] In the specific setup, a camera 302 is connected inside the water tank 1, and a display screen 301 is connected to the top of the water tank 1. The camera 302 and the display screen 301 are electrically connected. The camera 302 is used to record the state of the water droplets falling on the fabric when the drip head 2011 is close to the fabric and it is inconvenient for people to directly observe the state of the water droplets on the fabric with their eyes. The state of the water droplets falling on the fabric is recorded by the camera 302 and observed by the display screen 301.

[0050] In a specific configuration, the first circular plate 201 is connected to the outer surface of the second water pipe 303. The first circular plate 201 can remain stationary while the motor 202 drives the second circular plate 204 to rotate.

[0051] The working principle of the anti-vortex auxiliary component for water splash testing is as follows: When using the anti-vortex auxiliary component for water splash testing, the water flowing out of the spray device 4 flows through the second water pipe 303 and the third water pipe 304 into the interior of the first water pipe 206, and then through the connector 205 into the interior of the drip head 2011, from which it drips out. Furthermore, when the control motor 202 drives the second circular plate 204 to rotate, the vertical rod 208 moves within the sliding groove 207, allowing it to move in the direction of the moving track 2010, thus adjusting the timing of the water droplets. Position: When water droplets continuously drip in one spot, each impact injects kinetic energy near the point of impact, propelling the water flow outwards. Therefore, adjusting the position of the water droplets reduces the probability of eddy formation. The drip head 2011 can move up and down. When not dripping, the drip head 2011 should be far away from the fabric to facilitate fixing the fabric on the outer surface of the spray device 4. When dripping, the drip head 2011 should be closer to the fabric to reduce the impact force generated when the water droplets fall, further reducing the probability of eddy formation. This solves the problem of water droplets forming short-lived, rapidly rotating vortices on the fabric surface, which can be easily confused with actual seepage / wetting. Testers may mistakenly judge that the fabric has failed, when in fact it may be a hydrodynamic phenomenon caused by the impact force rather than a problem of insufficient surface energy of the fabric.

[0052] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
