Description

Technical Field

[0001] The embodiments disclosed herein belong to the field of experimental measurement technology, specifically relating to an apparatus for testing the anti-icing performance of coatings. Background Technology

[0002] In low-temperature, high-humidity environments, icing on the surfaces of equipment such as wind turbine blades and power transmission lines can lead to safety hazards such as decreased aerodynamic performance and mechanical load imbalance. The evaluation of the anti-icing performance of hydrophobic coatings relies on precise icing simulation tests. Currently, many coating icing experiments use temporary, fixed devices, which have significant drawbacks: First, the device angle adjustment is limited, failing to simulate the multi-angle icing scenarios caused by wind direction and gravity changes during actual blade operation; second, weighing requires disassembling the sample, which is cumbersome and easily damages the icing state, introducing human error; third, environmental parameters such as temperature, humidity, and rainfall need to be collected using separate equipment, separate from icing data, making it difficult to establish multi-factor correlation analysis models. Furthermore, traditional fixtures often use adhesive or drilling for fixation, resulting in unusable samples and increased experimental costs. These problems severely restrict the efficiency of hydrophobic and anti-icing coating development and the verification of its engineering applicability. Utility Model Content

[0037] To enable those skilled in the art to better understand the technical solutions of this disclosure, the disclosure will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1 to 8 As shown, an apparatus 100 for testing the anti-icing performance of coatings includes a support base 110, a bearing platform 120, an adjustment component 130, a monitoring component, and a weighing component. The bearing platform 120 is disposed on the support base 110 and includes a central truss 121, a first horizontal bearing component 122, and a second horizontal bearing component 123 rotatably connected to both sides of the central truss 121. One end of the adjustment component 130 is connected to the support base 110, and the other end is movably supported on the corresponding first horizontal bearing component 122 and second horizontal bearing component 123.

[0039] The monitoring component is located on the support platform 120 and is used to simultaneously collect ambient temperature, humidity, and rainfall data. The weighing component is correspondingly located on the first horizontal support component 122 and the second horizontal support component 123, and is used to receive the coating and weigh it in situ.

[0040] Specifically, such as Figures 1 to 8 As shown, the support platform 120 includes a central truss 121, which is mounted on the support base 110. A first horizontal support component 122 and a second horizontal support component 123 located on either side of the central truss 121 can rotate around the central truss 121, thereby simulating icing of the coating in various postures such as horizontal, inclined, and vertical, and supporting non-destructive fixation and in-situ real-time weighing. Simultaneously, the monitoring components can synchronously collect environmental temperature, humidity, and rainfall data, facilitating the subsequent generation of multi-dimensional correlation curves.

[0041] The apparatus for testing the anti-icing performance of coatings disclosed in this invention, through its supporting base, bearing platform, control components, monitoring components, and weighing components, can simulate icing of coating samples in multiple orientations, including horizontal, inclined, and vertical positions, and supports non-destructive fixation and real-time in-situ weighing. It can simultaneously collect relevant environmental parameters, facilitating the subsequent generation of multi-dimensional correlation curves. The apparatus also considers flexibility and scalability, significantly improving the accuracy, comprehensiveness, and efficiency of coating anti-icing performance evaluation.

[0042] Furthermore, both the first horizontal load-bearing component 122 and the second horizontal load-bearing component 123 include a first U-shaped frame 124 and multiple connecting rods 1241 spaced apart along the length of the first U-shaped frame 124. The first U-shaped frame 124 and the connecting rods 1241 are used to connect the weighing components.

[0043] Specifically, such as Figure 1 and Figure 2 As shown, the first horizontal load-bearing component 122 and the second horizontal load-bearing component 123 are distributed on the left and right sides of the central truss 121. The first U-shaped frame 124 and the connecting rod 1241 are used to connect the load-bearing components to support the coating through the load-bearing components.

[0044] For example, such as Figures 1 to 4 As shown, the weighing assembly includes a weighing element 140 and a suspension element 150. The first U-shaped frame 124 has a first crossbar 1242, a second crossbar 1243, and a side bar 1244 connecting the two. The connecting rod 1241 is connected to the weighing element 140, and the side bar 1244 is connected to the suspension element 150.

[0045] Furthermore, the connecting rod 1241 has at least one blind hole 12411 on the side opposite to the support base 110, which is used to place the weighing component 140. The side rod 1244 has at least one through hole 12441 extending through its thickness direction, which is used to connect the suspension component 150.

[0046] Furthermore, the weighing component 140 includes a first sensor 141 and a weighing plate 142, and the suspension component 150 includes a second sensor 151 and a hook 152. The first sensor 141 is housed within the blind hole 12411, and the weighing plate 142 overlaps the connecting rod 1241 and is connected to the first sensor 141. The weighing plate 142 is used to support the coating for weighing. The second sensor 151 is inserted into the through hole 12441, and one end of the hook 152 is connected to the second sensor 151, while the other end of the hook 152 is used to suspend the coating for weighing.

[0047] Specifically, such as Figures 1 to 4 As shown, the weighing component 140 is configured to be embedded in the blind hole 12411 of the connecting rod 1241, and the suspension component 150 is configured to be embedded in the through hole 12441 of the side rod 1244. The first end of the first sensor 141 is embedded in the blind hole 12411, and the weighing plate 142 is connected to the second end of the first sensor 141 and overlaps the connecting rod 1241. The second end of the first sensor 141 is flush with the upper surface of the connecting rod 1241. Preferably, a replaceable silicone-based film can be pasted on the upper surface of the weighing plate 142 to fix the coated sample and prevent it from slipping off without damaging the coated sample. The second sensor 151 is disposed in the through hole 12441. The upper and lower surfaces of the second sensor 151 are flush with the upper and lower surfaces of the side rod 1244, respectively. The lower surface of the second sensor 151 is connected to one end of the hook 152, and the sample is suspended through the other end of the hook 152.

[0048] For example, such as Figure 1 and Figure 2 As shown, the device 100 further includes a first hinge assembly 1211 and a second hinge assembly 1212 respectively connected to both ends of the central truss 121. The first end and the second end of the first hinge assembly 1211 are respectively connected to the free ends of the first crossbars 1242 located on both sides of the central truss 121. The first end and the second end of the second hinge assembly 1212 are respectively connected to the free ends of the second crossbars 1243 located on both sides of the central truss 121. The first hinge assembly 1211 and the second hinge assembly 1212 allow the first horizontal load-bearing assembly 122 and the second horizontal load-bearing assembly 123 to be rotatably connected to the central truss 121.

[0049] Specifically, such as Figure 1 and Figure 2 As shown, the first hinge assembly 1211 and the second hinge assembly 1212 are located at the left and right ends of the upper part, respectively, to connect the first crossbar 1242, so that the first horizontal bearing assembly 122 and the second horizontal bearing assembly 123 can rotate relative to the central truss 121 through the provided first hinge assembly 1211 and the second hinge assembly 1212.

[0050] Furthermore, the support base 110 includes a second U-shaped frame 111 and a third U-shaped frame 112. The two free ends of the second U-shaped frame 111 are respectively connected to the first hinge assembly 1211 and the third end of the second hinge assembly 1212, and the two free ends of the third U-shaped frame 112 are respectively connected to the first hinge assembly 1211 and the fourth end of the second hinge assembly 1212. The second U-shaped frame 111 and the third U-shaped frame 112 are rotatably connected to the central truss 121 through the first hinge assembly 1211 and the second hinge assembly 1212.

[0051] Specifically, the first hinge assembly 1211 and the second hinge assembly 1212 are located at the lower left and right ends, respectively, to connect the second U-shaped frame 111 and the third U-shaped frame 112, thereby allowing the second U-shaped frame 111 and the third U-shaped frame 112 to rotate relative to the central truss 121 via the provided first hinge assembly 1211 and second hinge assembly 1212. As an example, such as... Figure 1 As shown, the second U-shaped frame 111 and the third U-shaped frame 112 can form an inverted V-shaped support for each other, and the included angle between them is α.

[0052] For example, such as Figures 1 to 5 As shown, the support base 110 further includes a first load transfer rod 113, a second load transfer rod 114, and at least one stress distribution hinge 115. The first load transfer rod 113 and the second load transfer rod 114 are respectively connected to the second U-shaped frame 111 and the third U-shaped frame 112. The stress distribution hinge 115 includes a first stress arm 1151 connected at one end to the first load transfer rod 113, a second stress arm 1152 connected at one end to the second load transfer rod 114, and a truss hinge 1153 that respectively hinges the first stress arm 1151 and the second stress arm 1152. This further facilitates the rotation of the second U-shaped frame 111 and the third U-shaped frame 112 relative to the central truss 121.

[0053] The control component 130 is configured to include multiple adjustment columns. The first ends of the multiple adjustment columns are respectively connected to the first load transmission rod 113 and the second load transmission rod 114, and the second ends are respectively movably connected to the connecting rod 1241 of the first horizontal bearing component 122 and the second horizontal bearing component 123 in the form of a snap fastener, so as to support the first horizontal bearing component 122 and the second horizontal bearing component 123 to form a fixed tilt angle.

[0054] For example, such as Figures 1 to 6As shown, the monitoring component includes a rainfall measurement component 160 for synchronously collecting rainfall data, and the central truss 121 has a first receiving slot 200. One end of the rainfall measurement component 160 is hinged to the first receiving slot 200, which can accommodate the rainfall measurement component 160. The rainfall measurement component 160 includes a support rod 161 with one end hinged to the first receiving slot 200, and a piezoelectric rain gauge 162 disposed at the other end of the support rod 161.

[0055] Specifically, such as Figures 1 to 6 As shown, the central truss 121 has a first receiving slot 200, and the support rod 161 is mounted in the first receiving slot 200 via a hinge. A piezoelectric rain gauge 162 is mounted on the top of the support rod 161 for collecting rainfall data. Under the action of the hinge, the rainfall measuring component 160 can be housed in the first receiving slot 200 and extended when needed.

[0056] For example, such as Figures 1 to 8 As shown, the monitoring component also includes a temperature and humidity measuring component 170 for synchronously collecting environmental temperature and humidity data. A second receiving groove 300 is provided on the side of the first U-shaped frame 124. One end of the temperature and humidity measuring component 170 is hinged in the second receiving groove 300, which can accommodate the temperature and humidity measuring component 170. The temperature and humidity measuring component 170 includes a telescopic arm 171 with one end hinged in the second receiving groove 300, and a temperature and humidity measuring meter 172 disposed at the other end of the telescopic arm 171.

[0057] Specifically, such as Figure 7 and Figure 8 As shown, the second receiving slot 300 is used to house the temperature and humidity measuring component 170. When it is necessary to collect ambient temperature and humidity data, the temperature and humidity measuring component 170 is released from the second receiving slot 300; when it is not necessary to collect ambient temperature and humidity data, the temperature and humidity measuring component 170 can be housed in the second receiving slot 300. The temperature and humidity measuring component 170 includes a telescopic arm 171 and a temperature and humidity meter 172. The first end of the telescopic arm 171 is hinged to the second receiving slot 300, and the second end of the telescopic arm 171 is provided with a temperature and humidity meter 172 for collecting ambient temperature and humidity data. As an example, such as Figure 7 As shown, the telescopic arm 171 is configured to include at least two sub-telescopic members. One end of the first sub-telescopic member is hinged in the second receiving groove 300. The second sub-telescopic member can extend out of and retract into the first sub-telescopic member relative to the first sub-telescopic member. A temperature and humidity measuring instrument 172 is provided on the end of the second sub-telescopic member away from the first sub-telescopic member.

[0058] The apparatus for testing the anti-icing performance of coatings disclosed in this disclosure addresses the problems of single-angle testing devices, cumbersome weighing operations, and fragmented environmental data in related technologies. By integrating a multi-angle adjustable structure, an embedded weighing system, and a synchronous environmental monitoring module, it simulates icing of coating samples in multiple orientations, including horizontal, inclined, and vertical positions, and supports non-destructive fixation and real-time in-situ weighing. Built-in temperature and humidity measurement components and rainfall measurement components can simultaneously collect environmental parameters, facilitating the subsequent generation of multi-dimensional correlation curves. Its modular design balances flexibility and scalability, significantly improving the accuracy, comprehensiveness, and efficiency of coating anti-icing performance evaluation.

[0059] As a specific embodiment, the steps for using the above-mentioned device 100 are as follows:

[0060] Rotate the left first horizontal bearing assembly 122 and the right second horizontal bearing assembly 123 outwards until they are deployed at a preset angle with the central truss 121. Rotate the adjustment assembly 130 outwards until it connects with the connecting rod 1241 and confirm that the connection is secure, so that the adjustment assembly 130 and the connecting rod 1241 form a triangular support. Furthermore, the adjustment assembly 130 can be adjusted to cooperate and be fixed with different connecting rods 1241 to achieve different angle requirements.

[0061] Holding the second U-shaped frame 111 and the third U-shaped frame 112, extend them outward to a preset angle α. Observe the engagement state between the stress arm of the stress distribution hinge 115 and the load transfer rod, ensuring that the support base 110 is fixed in an inverted V shape. Place the coating sample on the surface of the weighing plate 142. After fixing the coating sample, which needs to be placed vertically, with a lightweight plastic clip, the plastic clip can also be hung on the hook 152. Rotate the temperature and humidity measuring component 170 and the rainfall measuring component 160 sequentially to a position perpendicular to the central truss 121.

[0062] After the test, clean the air vent of the piezoelectric rain gauge 162 with a dry cotton swab, and rotate the rain measurement component 160 into the first receiving slot 200. Retract the telescopic arm 171 and then rotate the temperature and humidity measurement component 170 to retract it into the second receiving slot 300. Disconnect the control component 130 from the connecting rod 1241, lift the central truss 121 upwards, and fold the main body of the device 110.

[0063] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of this disclosure, and this disclosure is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and substance of this disclosure, and these modifications and improvements are also considered to be within the scope of protection of this disclosure.
