Abstract
Description
Technical Field
[0001] This utility model relates to the field of viscosity testing instruments, specifically a portable viscosity testing device for aircraft de-icing and anti-icing fluid. Background Technology
[0002] In the performance testing of aircraft de-icing and anti-icing fluids, viscosity is a key indicator, directly determining the fluid's flow coverage and anti-icing adhesion on the aircraft surface. It needs to be quantitatively tested using a viscosity testing device. In actual testing, to avoid individual sample bias and ensure the representativeness and reliability of results, multiple samples must be tested when there are situations such as sample heterogeneity, abnormal or controversial test results, mandatory industry standards, or drastic fluctuations in ambient temperature. Furthermore, the viscosity of aircraft de-icing and anti-icing fluids is highly correlated with temperature; temperature changes cause significant viscosity fluctuations, thus affecting test accuracy. Traditional testing methods require placing the sample in a specialized temperature-controlled device, and replacing samples necessitates removing the old sample and placing the new one, which is cumbersome. Moreover, samples are easily affected by environmental factors during transfer, leading to temperature changes that disrupt temperature stability and distort test results. This makes it difficult to meet the requirements of efficient and accurate testing. Additionally, the temperature control device needs to be purchased separately, resulting in high costs.
[0003] Therefore, this utility model provides a portable viscosity testing device for aircraft de-icing and anti-icing fluid. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a portable viscosity testing device for aircraft de-icing and anti-icing fluids, thereby solving the aforementioned problems.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable viscosity testing device for aircraft de-icing and anti-icing fluid, comprising a support base, a viscometer, and a testing rotor. A handle is mounted on the back of the viscometer. A height-adjusting telescopic rod for the viscometer is mounted on the top of the support base. A rotating central rod and two sample cups are disposed on the top of the support base. The rotating central rod is rotatably connected to the top of the support base. Support seats are mounted at both ends of the rotating central rod. Both support seats slide circumferentially on the top of the support base. The two support seats alternately rotate to below the testing rotor. The testing rotor is inserted into the two sample cups. The sample cups are inserted into the inner walls of their respective support seats. Temperature regulators are mounted on the bottom sides of the interiors of both support seats, contacting the bottom of the corresponding sample cups to adjust the temperature of the samples inside the sample cups.
[0006] Preferably, a drive unit is installed at the bottom of the support base, and the output end of the drive unit is installed at the bottom of the rotating central rod to drive the rotating central rod to rotate.

[0008] Preferably, a plurality of spherical rolling elements are embedded in the bottom of both bearing seats, and the plurality of spherical rolling elements slide circumferentially on the top of the support base.
[0009] Preferably, a first magnetic ring is installed on the inner wall of each of the two bearing seats, the first magnetic ring being located outside the corresponding temperature regulator, and a second magnetic ring is installed at the bottom of each of the two sample bearing cups, the second magnetic ring being magnetically attracted to the top of the corresponding first magnetic ring.
[0010] Preferably, a heat insulation ring is installed on the outer top of each of the two sample carrier cups, and the sample carrier cups contact the clamping device or the operator's hand through the heat insulation ring. Beneficial effects
[0011] Compared with the prior art, the present invention has the following advantages: (1) This utility model, through two sample carrying cups and a rotatable carrying base, allows for quick switching of new samples without removing the old samples, avoiding the cumbersome operation of traditional sample replacement, and also reducing temperature changes caused by contact with the external environment during sample transfer, ensuring temperature stability and making the test results more accurate.

Detailed Implementation
[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-4 A portable viscosity testing device for aircraft de-icing and anti-icing fluid includes a support base 1, a viscometer 2, and a test rotor 21. A handle 22 is mounted on the back of the viscometer 2. A lifting telescopic rod 11 for height adjustment of the viscometer 2 is mounted on the top of the support base 1. A rotating central rod 3 and two sample cups 4 are located on the top of the support base 1. The rotating central rod 3 is rotatably connected to the top of the support base 1. Support seats 31 are mounted at both ends of the rotating central rod 3. Both support seats 31 slide annularly on the top of the support base 1. The two support seats 31 rotate alternately to below the test rotor 21. The test rotor 21 is inserted into the two sample cups 4, and the sample cups 4 are inserted into the inner walls of the corresponding support seats 31. Temperature regulators 32 are mounted on the bottom sides of the interiors of both support seats 31, contacting the bottom of the corresponding sample cups 4 to adjust the temperature of the samples inside the sample cups 4.
[0017] Specifically, the handle 22 facilitates the transfer and carrying of the device by the staff. During use, the operator injects different aircraft de-icing and anti-icing fluid samples into the two sample carrier cups 4 respectively. Then, the two sample carrier cups 4 are inserted into the inner walls of the two carrier seats 31. At this time, the temperature regulator 32 will be in close contact with the bottom of the sample carrier cup 4, preparing for subsequent precise temperature control. The sample in the sample carrier cup 4 remains at a constant temperature, improving the accuracy of the test. Subsequently, the height of the viscometer 2 is adjusted using the lifting telescopic rod 11, allowing the test rotor 21 to be precisely inserted into the sample in one of the sample carrier cups 4. Then, the viscometer 2 is started, and the test rotor 21 begins to perform viscosity testing on the sample. During the test, the temperature regulator 32 can adjust the temperature of the sample in the sample carrier cup 4 as needed. The viscosity of aircraft de-icing and anti-icing fluid is highly correlated with temperature. A stable and compliant temperature is crucial for obtaining accurate test results. The temperature regulator 32 ensures that the sample temperature is always kept within a suitable range, avoiding deviations in viscosity testing due to temperature fluctuations. When another sample needs to be tested, the rotating central rod 3 is rotated, causing the two carrier seats 31 to slide in a ring along the top of the support base 1. This smoothly rotates the sample carrier cup 4 containing the other sample directly below the test rotor 21. Then, the height of the viscometer 2 is finely adjusted again by the lifting telescopic rod 11, allowing the test rotor 21 to be accurately inserted into the sample. The viscometer 2 is then activated to perform the viscosity test. During this process, the temperature regulator 32 in the corresponding carrier seat 31 also precisely controls the temperature of the sample in the sample carrier cup 4.
[0018] In one embodiment of this utility model, such as Figures 1-4 As shown, a drive unit 12 is installed at the bottom of the support base 1. The output end of the drive unit 12 is installed at the bottom of the rotating central rod 3 to drive the rotating central rod 3 to rotate.
[0019] Specifically, the drive unit 12 at the bottom of the support base 1 provides power for the rotation of the rotating central rod 3. When it is necessary to switch samples, the drive unit 12 is activated, and its output end drives the rotating central rod 3 to rotate around the connection point at the top of the support base 1. This causes the bearing seats 31 at both ends of the rotating central rod 3 to slide in a ring on the top of the support base 1, so that the two bearing seats 31 can automatically rotate alternately to the bottom of the test rotor 21, realizing automatic sample switching without the need for manual rotation of the rotating central rod 3. This further improves the convenience and efficiency of sample switching, while ensuring the stability of the rotation process and avoiding sample splashing or temperature fluctuations in the sample carrier cup 4 due to uneven manual operation, thus ensuring a more stable and reliable detection process.
[0020] In one embodiment of this utility model, such as Figures 1-4As shown, a telescopic limiting rod 13 is installed at the bottom of the support base 1, and a limiting groove 311 is opened at the bottom of both bearing seats 31. The telescopic limiting rod 13 is inserted into the inner wall of the limiting groove 311.
[0021] Specifically, the telescopic limiting rod 13 at the bottom of the support base 1 cooperates with the limiting grooves 311 at the bottom of the two bearing seats 31 to achieve the positioning function. When the rotating central rod 3 drives the bearing seat 31 to slide in a ring on the top of the support base 1, and one of the bearing seats 31 rotates to the detection position directly below the test rotor 21, the telescopic limiting rod 13 will automatically extend, and its top end will be precisely inserted into the inner wall of the corresponding limiting groove 311 at the bottom of the bearing seat 31. The bearing seat 31 is fixed by the mechanical structure, preventing the bearing seat 31 from shifting due to slight external collisions, vibrations or the contact force of the test rotor 21 during the detection process. This ensures that the sample bearing cup 4 is in a stable position and that the test rotor 21 can always be accurately inserted into the sample, avoiding detection deviation or sample splashing due to bearing seat displacement.
[0022] In one embodiment of this utility model, such as Figures 1-4 As shown, several spherical rolling elements 312 are embedded in the bottom of both bearing seats 31, and the several spherical rolling elements 312 slide in a ring on the top of the support base 1.
[0023] Specifically, several spherical rolling elements 312 are embedded in the bottom of the two bearing seats 31 to optimize the relative movement between the bearing seats 31 and the top of the support base 1. When the rotating central rod 3 drives the bearing seat 31 to slide in a ring along the top of the support base 1 to switch samples, the spherical rolling elements 312 will contact the top surface of the support base 1 and replace the sliding friction between the bottom of the bearing seat 31 and the top of the support base 1 by rolling themselves. By converting sliding friction into rolling friction, the friction force during the movement of the bearing seat 31 is greatly reduced. On the one hand, this reduces the power required for the rotating central rod 3 to drive the bearing seat 31, making the ring sliding of the bearing seat 31 smoother and more stable, and avoiding the bearing seat 31 from jamming or shaking due to excessive friction.
[0024] In one embodiment of this utility model, such as Figures 1-4 As shown, a first magnetic ring 33 is installed on the inner wall of both bearing seats 31. The first magnetic ring 33 is located outside the corresponding temperature regulator 32. A second magnetic ring 41 is installed at the bottom of both sample bearing cups 4. The second magnetic ring 41 is magnetically attracted to the top of the corresponding first magnetic ring 33.
[0025] Specifically, the first magnetic ring 33 on the inner wall of the two support seats 31 and the second magnetic ring 41 at the bottom of the corresponding sample support cup 4 achieve precise positioning and stable connection between the sample support cup 4 and the support seat 31 through magnetic adsorption. When the sample support cup 4 is inserted into the inner wall of the support seat 31, as the sample support cup 4 gradually approaches the bottom of the support seat 31, the second magnetic ring 41 at the bottom of the sample support cup 4 will generate a magnetic attraction with the first magnetic ring 33 on the inner wall of the support seat 31. Guided by this attraction, the sample support cup 4 can automatically align with the center position of the support seat 31, quickly and accurately completing the insertion without the need for repeated manual adjustments, thus improving the installation efficiency of the sample support cup 4 and strengthening the contact stability between the sample support cup 4 and the temperature regulator 32, thereby improving the stability of temperature regulation.
[0026] In one embodiment of this utility model, such as Figures 1-4 As shown, both sample carrier cups 4 are equipped with heat insulation rings 42 on the outer top of their respective cups. The sample carrier cups 4 are in contact with the clamps or the operator's hand through the heat insulation rings 42.
[0027] Specifically, the heat insulation ring 42 is made of heat-insulating material, which can block the heat of the sample carrier cup 4 from being transferred to the top, preventing the high or low temperature of the cup from being directly conducted to the clamping parts or the operator's hands, preventing the clamping parts from being damaged due to abnormal temperature, and protecting the operator's hands from frostbite or burns, thus improving operational safety. The heat insulation ring 42 can also serve as an "auxiliary grip" for the sample carrier cup 4. When the operator picks up or puts down the sample carrier cup 4, they can directly contact the heat insulation ring 42 without having to find additional heat insulation tools, thus balancing operational convenience and safety and optimizing the operational experience during sample replacement.
[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0029] Working principle: When this portable viscosity testing device is in operation, samples of different aircraft de-icing and anti-icing fluids are first injected into two sample carrier cups 4, and then inserted into the inner wall of the carrier base 31. At this time, the second magnetic ring 41 at the bottom of the sample carrier cup 4 is magnetically attracted to the first magnetic ring 33 on the inner wall of the carrier base 31, achieving precise alignment and strengthening the contact with the temperature regulator 32. The temperature regulator 32 is in contact with the bottom of the sample carrier cup 4 to accurately control the temperature of the sample and avoid temperature fluctuations affecting the test. The height of the viscometer 2 is adjusted by the lifting telescopic rod 11 so that the test rotor 21 is inserted into one of the sample carrier cups 4. When a sample is sampled, the viscometer 2 is activated to complete the test. When switching samples, the drive unit 12 drives the rotating central rod 3 to rotate. The spherical rolling body 312 at the bottom of the support seat 31 converts sliding friction into rolling friction, allowing the support seat 31 to slide smoothly in a ring. When the target support seat 31 is below the test rotor 21, the telescopic limit rod 13 extends and inserts into the limit groove 311 to fix it. When picking up or putting down the sample support cup 4, the heat insulation ring 42 blocks the temperature transfer, protecting the operator's hands and the clamping parts, and can also assist in holding the sample. The entire process does not require an additional temperature control device, realizing efficient switching and accurate detection of multiple samples, and ensuring reliable results.
