Description

Technical Field

[0001] This utility model belongs to the technical field of material environmental adaptability verification equipment, specifically relating to a dynamic in-situ icing detection test bench with multi-physics field sensing. Background Technology

[0002] Ice buildup on wind turbine blades in extreme weather conditions can lead to annual power generation losses of over 12%. Testing anti-icing coatings on wind turbine blades is a crucial step in ensuring their stable operation under extreme weather conditions.

[0003] Current anti-icing coating testing technologies face three major technological gaps: First, static test benches cannot reproduce the complex tilt angle icing caused by blade yaw and pitch changes; second, weighing requires interrupting the experiment, disrupting the continuity of the ice layer; and third, the asynchronous acquisition of environmental parameters and icing growth data makes it difficult to establish multi-factor coupled models. Current automated solutions largely rely on large climate chambers, which suffer from drawbacks such as large equipment footprint and weak data visualization. To address these bottlenecks, there is an urgent need to develop desktop-level integrated testing equipment that achieves millimeter-level spatial positioning accuracy, millisecond-level data refresh, and multi-parameter three-dimensional dynamic presentation to meet the high-throughput testing requirements of next-generation anti-icing material development.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 13 , Figure 14 , Figure 16 As shown in the figure, the multi-physics sensing dynamic icing in-situ detection test bench provided by the specific embodiment of this utility model includes a bearing platform unit 110, an operation platform 200 and a weighing component 500.

[0018] The bearing platform unit 110 includes a first bearing platform 120 for horizontal and inclined weighing and a second bearing platform 130 for horizontal, inclined and vertical weighing. The first bearing platform 120 is connected to the operating platform 200 via a first column leg 123. The second bearing platform 130 is slidably mounted on the slide rail 201 of the operating platform 200 via a track 131 on the second column leg 133. A bearing crossbar 121 is installed on both the first column leg 123 and the second column leg 133. The two ends of the bearing crossbar 121 are connected to the first column leg 123 and the second column leg 133 via an angle adjustment mechanism 600.

[0019] The angle adjustment mechanism 600 consists of connecting units at both ends of the bearing crossbar 121, limiting grooves in the first column leg 123 and the second column leg 133, and elastic limiting components connected to the connecting units and locked in the limiting grooves. The bearing crossbar 121 rotates in the limiting grooves of the first column leg 123 and the second column leg 133 through the connecting units at both ends and the elastic limiting components.

[0020] The operating platform 200 is provided with a receiving slot 213 for placing the rainfall sensor component 210, which includes a rainfall measurement component 214 for synchronously collecting rainfall data.

[0021] The weighing assembly 500 includes a multi-angle weighing assembly 510 and a vertical weighing assembly 520.

When adjusting the angle, the bearing crossbar 121 is rotated. The connecting end face 605 connects to the elastic element 602, which drives the lever 601 to make a circular motion along the side surface 611 of the groove to achieve angle adjustment. When stationary, due to the elastic force of the elastic element 602, the lever 601 is pressed tightly against the bottom surface 610 of the groove and remains stationary under the action of friction between the two. The bearing crossbar 121 has at least one first through hole 121, which is used to install the weighing component 510. The second column leg 133 has at least one second through hole 132, which is used to connect the vertical weighing component 520.

[0024] Furthermore, the operating platform 200 includes an integrated storage unit 300, which is provided with a first storage space 202 and a second storage space 203, which are separated by a partition 207.

[0031] The vertical weighing assembly 520 includes a second micro sensor 525 and a hook 521. The second micro sensor 525 is inserted into the second through hole 132 on the second column leg 133. One end of the hook 521 is connected to the second micro sensor 525, and the other end of the hook 521 is used to suspend the coating sample for weighing. Specifically, the upper surface of the second micro sensor 525 is flush with the upper surface of the second column leg 133, and the upper surface of the first micro sensor 514 is flush with the upper surface of the bearing crossbar 121. Preferably, the upper surface of the fixing assembly 515 can be pasted with a silicone-based replaceable film to fix the coating sample and prevent the sample from slipping, without damaging the coating sample.

[0032] It should be noted that, in this embodiment, the data from the weighing component 500, the rainfall sensing component 210, the rainfall measuring component 214, and the temperature and humidity sensor component 220 are all transmitted and displayed on the screen 240 through a reasonable connection method.

[0036] The steps for using this device are as follows: After placing the test bench 100 in a suitable position, unfold the second bearing platform 130 horizontally and rotate the bearing crossbar 121 to change the horizontal or tilt angle as needed. The coating sample is placed on the weighing plate surface of the multi-angle weighing assembly 510, and after the coating sample that needs to be placed vertically is fixed with a lightweight plastic clip, the plastic clip can also be hung on the hook 521. Pull out the integrated temperature and humidity sensor assembly 220 in sequence and rotate the temperature and humidity measuring instrument 228 to keep it horizontal with the remote telescopic arm 223, and rotate the rain sensor assembly 210 to a position perpendicular to the support crossbar 121. After the test, the second support platform 130 is horizontally pushed back, the piezoelectric rain gauge 211 is cleaned with a dry cotton swab, and the rain sensor assembly 210 is rotated into the receiving slot 213. The proximal telescopic arm 221 and the distal telescopic arm 223 are retracted, and then the temperature and humidity meter 228 is rotated to retract into the storage hole 230.

[0037] In summary, the embodiments disclosed herein have at least the following technical effects: Through the first and second load-bearing platforms, combined with adjustable-angle load-bearing crossbars and angle adjustment mechanisms, the system can flexibly adapt to load testing requirements in different directions and angles, covering complex mechanical scenarios during icing (such as ice load distribution at different inclination angles). The multi-angle weighing components and vertical weighing components employ miniature sensors (including magnetically fixed trays and hook suspension designs) to achieve real-time dynamic weighing with millimeter-level accuracy, meeting the need for precise monitoring of icing quality changes. The integrated storage unit (drawer-type design) and slide rail system of the operating platform facilitate quick replacement of test samples, tools, and sensor components, improving experimental efficiency. The angle adjustment mechanism (lever + elastic element + groove) and sliding load-bearing platform design allow for rapid adjustment of equipment posture and position to adapt to different experimental scenarios. The piezoelectric rain gauge, installed via a hinge structure, can stably collect rainfall data, combined with simulation of liquid water input during dynamic icing. The telescopic arm-designed temperature and humidity sensor components can flexibly adjust the measurement position, simultaneously collecting environmental parameters such as temperature and humidity, providing crucial data support for icing formation conditions. This device integrates sensors for rainfall, temperature, humidity, and weighing, enabling coupled analysis of multiple physical fields (mechanical, thermal, and hydrological) to fully reproduce the complex interactions in a real icing environment. The bottom-mounted moving components (rubber wheels + mounting plate) make the device portable and adaptable to various deployment needs in laboratories, fields, or engineering sites. Piezoelectric sensors, miniature weighing modules, and telescopic arm designs reduce manual intervention and improve the continuity and real-time nature of data acquisition. Limiting components, magnetically fixed trays, and sliding assembly structures (such as the combination of column legs and slide rails) ensure the device's mechanical stability during dynamic testing, reducing equipment wear and error risks. Multi-sensor data can be synchronously transmitted to the screen, supporting multi-source data fusion analysis and providing reliable evidence for icing mechanism research and protection strategy optimization. Weighing, temperature, and humidity monitoring can be performed without removing the sample from the test environment, preserving the continuity and authenticity of the icing process. It supports static and dynamic icing tests (such as rain erosion and ice growth rate), suitable for research needs in multiple fields such as coating performance evaluation, material anti-icing research, and anti-icing technology verification.

For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
