[0040] The spray method tests the hydrophobicity of the organic insulating material sample by spraying water mist on the organic insulating material sample, and taking a photo of the organic insulating material sample when the water mist particles spray on the organic insulating material sample by using a camera.

As shown in the figure, Figures 1 to 3 The hydrophobicity testing device provided by the present embodiment is used to test the hydrophobicity of the sample 100. The hydrophobicity testing device includes a test table 1 and a test assembly 2. The test table 1 includes a base 11, a carrying table 12, and a first driving member 13. The first end of the carrying table 12 is pivoted to the base 11, and the sample 100 is placed on the carrying table 12. The first driving member 13 is fixedly connected to the base 11, and the output end of the first driving member 13 is connected to the second end of the carrying table 12, which is opposite to the first end, so that the carrying table 12 can rotate relative to the base 11. The test assembly 2 includes a mounting bracket 21, a camera 22, and a spray head 23. The mounting bracket 21 is fixedly connected to the carrying table 12. The camera 22 is installed on the mounting bracket 21 and is arranged to face the sample 100. The spray head 23 is located above the sample 100 and is used to spray water mist. The spray head 23 is installed on the mounting bracket 21 and faces the sample 100. A controller is in communication connection with the first driving member 13, the camera 22, and the spray head 23, and is used to:

[0042] Control the first driving member 13 to rotate the carrying table 12 relative to the base 11, and adjust the spray angle of the spray head 23 relative to the sample 100;

[0044] Analyze the photo of the sample 100 sprayed by the water mist particles taken by the camera 22 to analyze the hydrophobicity of the sample 100.

[0045] The hydrophobicity testing device provided by the embodiment can place the sample 100 on the bearing table 12, install the spray head 23 on the mounting bracket 21 and towards the sample 100, and locate the spray head 23 above the sample 100 and capable of spraying water mist. The controller is in communication connection with the spray head 23, so that the particle size of the water mist can be controlled. The first end of the bearing table 12 is pivoted to the base 11, the first driving member 13 is fixedly connected to the base 11, the controller is in communication connection with the first driving member 13, the output end of the first driving member 13 is connected to the second end of the bearing table 12, so that the bearing table 12 can rotate relative to the base 11, thereby the spray angle of the spray head 23 relative to the sample 100 can be controlled. The camera 22 is installed on the mounting bracket 21 and towards the sample 100, so that the sample 100 can be photographed and analyzed when the sample 100 is sprayed by the water mist particles under the condition that the particle size of the water mist and the spray angle are controlled, the hydrophobicity of the sample 100 can be analyzed, a unified testing standard can be established, and the testing can be performed on the sampling site to ensure the accuracy of the testing result.

[0046] In the embodiment, the controller can be a programmable logic controller, a microcomputer or other control element capable of being in communication connection with the first driving member 13, the camera 22 and the spray head 23, controlling the first driving member 13 and the spray head 23, and analyzing the photos taken by the camera 22 to analyze the hydrophobicity of the sample 100.

[0047] In the embodiment, the mounting bracket 21 is provided with a first connecting hole, the bearing table 12 is provided with a first fixing hole, and the first locking member passes through the first connecting hole and is in matched connection with the first fixing hole, so that the mounting bracket 21 can be fixedly connected to the bearing table 12. Specifically, the first connecting hole is a through hole, the first fixing hole is a threaded hole, and the first locking member is a bolt, which is in threaded connection with the threaded hole through the through hole, so that the mounting bracket 21 is fixedly connected to the bearing table 12.

[0048] In the embodiment, the camera 22 is provided with a second connecting hole, the mounting bracket 21 is provided with a second fixing hole, and the second locking member passes through the second connecting hole and is in matched connection with the second fixing hole, so that the camera 22 can be installed on the mounting bracket 21 and set towards the sample 100. Specifically, the second connecting hole is a through hole, the second fixing hole is a threaded hole, and the second locking member is a bolt, which is in threaded connection with the threaded hole through the through hole, so that the camera 22 is installed on the mounting bracket 21.

[0049] In the embodiment, the third connecting hole is a through hole, the fourth fixing hole is a threaded hole, and the fourth locking member is a bolt. The bolt is screwed through the through hole and the threaded hole, so as to fix the first driving member 13 to the base 11.

[0050] In the embodiment, the fourth connecting hole is arranged on the first driving member 13, and the fourth fixing hole is arranged on the base 11. The fourth locking member is arranged to pass through the fourth connecting hole and be connected to the fourth fixing hole, so as to fix the first driving member 13 to the base 11. Specifically, the fourth connecting hole is a through hole, the fourth fixing hole is a threaded hole, and the fourth locking member is a bolt. The bolt is screwed through the through hole and the threaded hole, so as to fix the first driving member 13 to the base 11.

[0051] In the embodiment, the type of the first driving member 13 is not limited. The first driving member 13 can be an electric push rod, a pneumatic cylinder, an oil cylinder, or a linear module. As long as the output end of the first driving member 13 can be connected to the second end of the bearing table 12 and be in communication connection with the controller, the controller can control the first driving member 13 to rotate the bearing table 12 relative to the base 11.

[0052] It should be noted that the hydrophobicity testing device provided in the embodiment can not only test the hydrophobicity of organic insulating materials, but also test the hydrophobicity of other materials. As long as the material can be sampled and placed on the bearing table 12, the hydrophobicity of the material can be tested.

[0053] As shown in FIG. 1, Figure 3 In combination with Figure 1 As shown in FIG. 1, the test table 1 further includes a limiting table 14. The limiting table 14 is fixedly connected to the bearing table 12. A limiting groove 141 is formed in the end face of the limiting table 14 facing the spray head 23. The sample 100 is embedded in the limiting groove 141, so as to roughly limit the position of the sample 100 on the bearing table 12, to ensure that the spray head 23 can be aligned with the sample 100, so that the water mist particles sprayed by the spray head 23 can fall on the sample 100. At the same time, the sample 100 is prevented from sliding when the bearing table 12 rotates relative to the base 11, so that the water mist particles sprayed by the spray head 23 cannot fall on the sample 100.

[0054] In the embodiment, the limiting table 14 is provided with a fifth connecting hole, the bearing table 12 is provided with a fifth fixing hole, and the fifth connecting hole is connected with the fifth fixing hole through a fifth locking piece, so that the limiting table 14 is fixedly connected to the bearing table 12. Specifically, the fifth connecting hole is a through hole, the fifth fixing hole is a threaded hole, and the fifth locking piece is a bolt. The bolt is screwed into the threaded hole, so that the limiting table 14 is fixedly connected to the bearing table 12.

[0055] In some embodiments, the limiting table 14 can also be integrally formed with the bearing table 12, as long as a limiting groove 141 is formed therein, and the sample 100 is embedded in the limiting groove 141 to be limited in the spatial position on the bearing table 12.

[0056] As shown in Figure 3 , the peripheral side wall of the sample 100 is spaced apart from the inner side wall of the limiting groove 141, so that the limiting groove 141 can accommodate the spray water gathered into a stream after being sprayed onto the surface of the sample 100, simulate the actual environment in which the sample 100 is soaked in rainwater under natural environmental conditions, and further improve the accuracy of the test result of the hydrophobicity test device.

[0057] Figure 4 A cross-sectional view in the A-A direction of Figure 3 is shown. Because the sample 100 is sometimes arranged to be inclined to the ground in the actual working environment and is not soaked in rainwater, the accuracy of the test result of the hydrophobicity test device will be affected if the sample 100 is soaked in rainwater. To solve the above technical problem, as shown in Figure 4 in combination with Figures 2 to 3 , a first drainage port 142 communicating with the limiting groove 141 is formed in the side wall of the limiting table 14 facing the first end of the bearing table 12, and a valve is arranged at the first drainage port 142. Therefore, when it is necessary to simulate that the sample 100 is soaked in rainwater, the valve can be closed to soak the sample 100 in the spray water gathered into a stream, and when it is not necessary to simulate that the sample 100 is soaked in rainwater, the valve can be opened to drain the spray water gathered into a stream out of the limiting groove 141 through the first drainage port 142, thereby improving the accuracy of the test result of the hydrophobicity test device.

[0058] Continuing to be shown in Figure 4 in combination with Figures 2 to 3 , a plurality of limiting tables 14 are fixedly connected to the bearing table 12 and arranged in an M×K (M≥1 and is an integer, K≥1 and is an integer) array, so that the hydrophobicity test device can simultaneously test a plurality of samples 100 at a time, and the accuracy of the test result is improved by increasing the number of test samples. It should be noted that the number of limiting tables 14 can be one, two, three, four, five, six, ten, or even more. Those skilled in the art can reasonably set the number of limiting tables 14 according to the needs of the actual test scheme.

[0059] In the embodiment, the six limiting tables 14 are arranged in a 2*3 array, so that the water repellency testing device can test the water repellency of six samples 100 at one time, further improving the accuracy of the test results of the water repellency testing device.

[0060] Preferably, the number of spray heads 23 is the same as the number of limiting tables 14, and each spray head 23 respectively faces one limiting table 14, so that when the water repellency testing device tests multiple samples 100 at the same time, it can ensure that the samples 100 can be uniformly sprayed by the water mist, preventing uneven spraying of multiple samples 100, which can adversely affect the water repellency test results.

[0061] As shown in Figure 2 In combination Figure 1 As shown in the figure, the mounting frame 21 is slidingly connected to the bearing table 12 in the vertical direction, so that it can slide in the vertical direction to adjust the distance of the spray head 23 relative to the sample 100, and further adjust the movement distance of the water mist particles falling on the sample 100, which can more realistically simulate the washing of the sample 100 by natural rainfall, further improving the accuracy of the test results of the water repellency testing device.

[0062] In the embodiment, the test assembly 2 further comprises a second driving member 24, which is fixedly connected to the bearing table 12, and the output end of the second driving member 24 is connected to the mounting frame 21. The second driving member 24 is in communication connection with the controller, so that the controller can control the second driving member 24 to move, and the mounting frame 21 can slide relative to the bearing table 12 in the vertical direction to adjust the distance of the spray head 23 relative to the sample 100. Specifically, the type of the second driving member 24 is not limited, which can be an electric push rod, a pneumatic cylinder, an oil cylinder or a linear module, as long as its output end can be connected to the mounting frame 21 and in communication connection with the controller, so that the controller can control the mounting frame 21 to slide relative to the bearing table 12 in the vertical direction to adjust the distance of the spray head 23 relative to the sample 100.

[0063] In the embodiment, the second driving member 24 is provided with a sixth connecting hole, and the bearing table 12 is provided with a sixth fixed hole. The sixth locking member passes through the sixth connecting hole to be connected with the sixth fixed hole in cooperation, so that the second driving member 24 can be fixedly connected to the bearing table 12. Specifically, the sixth connecting hole is a through hole, the sixth fixed hole is a threaded hole, and the sixth locking member is a bolt. The bolt is screwed into the threaded hole to fixedly connect the second driving member 24 to the bearing table 12.

[0064] As shown in Figure 2As shown, the test bench 1 further comprises a rotating wheel 15, a rotating shaft of the rotating wheel 15 is rotatably connected to the base 11, so as to facilitate the staff to push the hydrophobicity testing device to the sampling site, and improve the use convenience of the hydrophobicity testing device. Specifically, the rotating wheel 15 can be a caster or a wheel, as long as the rotating shaft thereof is rotatably connected to the base 11, so that the staff can push the hydrophobicity testing device.

[0065] As shown in the figure, Figure 4 In combination with Figures 2 to 3 As shown, the test bench 1 further comprises a wind shielding piece 16, the wind shielding piece 16 is fixedly connected to the bearing table 12, and a plurality of wind shielding pieces 16 are arranged to form a containing space for containing the sample 100, so as to prevent the natural wind from blowing the sample 100 during the hydrophobicity test of the sample 100, thereby avoiding the adverse effect on the hydrophobicity test result. It should be noted that the sample 100 in the embodiment is embedded in the limiting groove 141 of the limiting table 14, and the sample 100 is contained in the limiting space, that is, the limiting table 14 is also contained in the limiting groove 141.

[0066] In the embodiment, specifically, the wind shielding piece 16 is a wind shielding plate, four wind shielding plates are arranged at the edge of the bearing table 12 and are arranged to extend upward in the vertical direction, thereby forming a containing cavity for containing the sample 100. It should be noted that the wind shielding plate only prevents the natural wind from blowing the sample 100, and does not adversely affect the water mist particles sprayed by the spray head 23 from falling on the sample 100.

[0067] In the embodiment, the wind shielding piece 16 is provided with a seventh connecting hole, the bearing table 12 is provided with a seventh fixing hole, and the seventh locking piece passes through the seventh connecting hole and is connected with the seventh fixing hole in a matched mode, so as to fix and connect the wind shielding piece 16 to the bearing table 12. Specifically, the seventh connecting hole is a through hole, the seventh fixing hole is a threaded hole, and the seventh locking piece is a bolt, which is screwed with the threaded hole through the through hole, so as to fix and connect the wind shielding piece 16 to the bearing table 12.

[0068] In some embodiments, the wind shielding piece 16 can also be integrally formed with the bearing table 12, as long as it can surround the containing space for containing the sample 100.

[0069] In some embodiments, the sample 100 is directly placed on the bearing table 12 and is also located inside the containing space surrounded by the wind shielding piece 16.

[0070] Continuing as Figure 4 In combination with Figures 2 to 3As shown, the wind shield 16 is provided with a second water outlet 161 on the side wall opposite to the first end of the bearing table 12, which is in communication with the containing space, so that the water mist sprayed by the shower head 23 does not fall on the sample 100 but on the bearing table 12, and when the bearing table 12 is arranged to be inclined relative to the ground by rotating relative to the base 11, the water mist particles can be converged into a flow and discharged from the containing space through the second water outlet 161, preventing the shower water converged by the water mist particles from accumulating in the containing space and flowing to the sample 100 to adversely affect the result of the hydrophobicity test.

[0071] The embodiment also provides a hydrophobicity test method, which applies the hydrophobicity test device, and the test method comprises the following steps: adjusting the inclined posture of the sample 100, controlling the spray angle of the shower head 23 relative to the sample 100, spraying the sample 100 by the shower head 23, controlling the particle size of the water mist, taking a photo of the sample 100 by the camera 22, and analyzing the hydrophobicity of the sample 100 by the controller, so that the photo of the sample 100 sprayed by the water mist particles can be taken and analyzed again on the basis that the size of the water mist particles and the spray angle are both controlled, the hydrophobicity of the sample 100 is analyzed, a unified test standard is established, and the test can be performed on the sampling site to ensure the accuracy of the test result. The specific steps are as follows:
