Description

Technical Field

[0001] This utility model relates to the field of hydrophobicity testing technology, specifically a portable hydrophobicity testing device. Background Technology

[0002] Hydrophobicity is a technical indicator reflecting a material's resistance to water penetration. It is expressed as the volume percentage of the unpermeable portion of a sample after being sprayed with water at a certain flow rate in a specified manner. The hydrophobicity of a substance is due to the action of hydrophobic groups, which are generally CH bonds, such as in oily substances. In the composite insulator industry, hydrophobicity is also known as wettability, which is determined by the surface tension of the outer insulation of the composite insulator and characterizes the ability of water to wet the outer insulation of the composite insulator.

[0003] Existing hydrophobicity testing devices are not convenient to use. Operators need to hold the device for a long time to spray the material to be tested. The operator's hand operation cannot guarantee the stability of the device, which will cause the material area to be tested to shift, resulting in errors in the test results.

[0004] Therefore, a portable hydrophobicity testing device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a portable hydrophobicity testing device to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: A portable hydrophobicity testing device includes a device body and an annular sliding plate. Four mounting slots are equally spaced on the outer side of the device body. A support slide rod is installed inside each of the four mounting slots. A first spring is installed on the outer side of the support slide rod. Four sliders are equally spaced on the inner side of the annular sliding plate. One end of each slider is slidably sleeved on the outer side of the support slide rod. Multiple support rods are equally spaced on the bottom end of the annular sliding plate. An annular base plate is installed on the bottom end of each support rod. A connecting seat is installed on each of the two sides of the top of the device body. A handle is hinged between two of the connecting seats.

[0006] Preferably, a limiting block is installed on each side of the main body of the device, and a limiting rod is movably installed inside the limiting block. A second spring is installed on the outside of the limiting rod, and a limiting groove is formed at the bottom of the limiting block.

[0007] Preferably, a plug is installed on each of the two sides of the top of the annular slide plate, and a fixing groove is provided on one side of the plug.

[0008] Preferably, one end of the limiting rod is used in conjunction with the top end of the insertion rod.

[0009] Preferably, a water inlet is installed at the top of the main body of the device, and a water storage bottle is movably installed on the top of the water inlet.

[0010] Preferably, the annular sliding plate and the annular base plate are both annularly hollow, and multiple rubber anti-slip pads are installed at equal intervals at the bottom end of the annular base plate.

[0011] Preferably, a camera is installed at the bottom center of the main body of the device, and multiple water mist nozzles are installed in a ring around the bottom of the main body of the device. The water mist nozzles are used in conjunction with a water storage bottle.

[0012] Preferably, the handle is semi-circular in shape.

[0013] Compared with the prior art, the present invention provides a portable hydrophobicity testing device, which has the following advantages:

[0014] The device is equipped with a ring-shaped sliding plate, a support rod, a ring-shaped base plate, sliders, a support slide rod, and a first spring. Because the ring-shaped sliding plate is slidably mounted on the outside of the support slide rod via multiple sliders installed on its inner side, the entire ring-shaped sliding plate can slide along the installation direction of the support slide rod. The ring-shaped base plate and support rod provide support, lifting the entire device body. This facilitates hydrophobicity testing of the material area to be tested at the bottom of the device body. During the hydrophobicity test, the operator does not need to hold the device throughout the process; simply align the bottom of the device body with the area to be tested. The device remains stationary during the test, thus improving the accuracy of the test data. Attached Figure Description

[0021] 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.

[0022] Example 1: Four mounting slots 7 are equally spaced on the outer side of the main body 1 of the device. A support slide rod 15 is installed inside each of the four mounting slots 7. A first spring 12 is installed on the outer side of the support slide rod 15. Four sliders 14 are equally spaced on the inner side of the annular slide plate 2. One end of the slider 14 is slidably sleeved on the outer side of the support slide rod 15. Multiple support rods 6 are equally spaced on the bottom end of the annular slide plate 2. An annular base plate 11 is installed on the bottom end of the support rods 6. A connecting seat 5 is installed on each of the two sides of the top of the main body 1 of the device. A handle 4 is hinged between the two connecting seats 5.

[0023] Specifically, such as Figure 1 , Figure 3 and Figure 5 As shown, since the annular slide plate 2 is slidably mounted on the outside of the support slide rod 15 via multiple sliders 14 installed on the inner side, the entire annular slide plate 2 can slide along the installation direction of the support slide rod 15. Since the bottom end of the annular slide plate 2 is equipped with an annular base plate 11 via multiple support rods 6, the entire device can be placed on the ground via the annular base plate 11. Since the outside of the support slide rod 15 is equipped with a first spring 12, the elastic force of the first spring 12 can push the slider 14 to the bottom of the support slide rod 15, thereby pushing the annular slide plate 2 together with the annular base plate 11 to the bottom end of the device body 1. The support of the annular base plate 11 and the support rods 6 can lift the entire device body 1, thus facilitating the hydrophobicity test of the material area to be tested at the bottom end of the device body 1. During the hydrophobicity test, the operator does not need to hold the device throughout the process; the bottom of the device body 1 only needs to be aligned with the area to be tested. During the test, the entire device will not shift in position, thereby improving the accuracy of the test data.

[0024] Since the top of the main body 1 of the device is hinged to the handle 4 via the connecting seat 5, the operator can easily carry the entire device through the handle 4. When the device is in use, the handle 4 can be rotated and placed on the top of the main body 1 of the device without affecting the normal use of the device.

[0025] Example 2: A limiting block 17 is installed on each side of the main body 1 of the device, and a limiting rod 21 is movably installed inside the limiting block 17. A second spring 20 is installed on the outside of the limiting rod 21. A limiting groove 18 is opened at the bottom of the limiting block 17. An insert rod 13 is installed on each side of the top of the annular slide plate 2, and a fixing groove 19 is opened on one side of the insert rod 13. One end of the limiting rod 21 is used in conjunction with the top of the insert rod 13. A water inlet 3 is installed at the top of the main body 1 of the device, and a water storage bottle 16 is movably installed on the top of the water inlet 3. The annular slide plate 2 and the annular base plate 11 are respectively annularly hollow. Multiple rubber anti-slip pads 10 are installed at equal intervals at the bottom of the annular base plate 11. A camera 8 is installed at the center of the bottom of the main body 1 of the device, and multiple water mist nozzles 9 are installed in a ring at the bottom of the main body 1 of the device. The water mist nozzles 9 are used in conjunction with the water storage bottle 16. The handle 4 is semi-circular.

[0026] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, after the device is used, the annular slide plate 2, together with the annular base plate 11, can be slid upwards along the outer side of the device body 1, so that the insert rods 13 installed on both sides of the top of the annular slide plate 2 are respectively inserted into the limiting grooves 18 opened at the bottom of the limiting blocks 17 installed on both sides of the device body 1. When the insert rods 13 are inserted into the limiting grooves 18, they will squeeze the limiting rods 21, thereby causing one end of the limiting rods 21 to retract and compress the second spring 20. When the top of the insert rods 13 is completely inserted into the limiting grooves 18, the second spring 20 will rebound, thereby causing one end of the limiting rods 21 to be inserted into the fixing grooves 19, fixing the insert rods 13 inside the limiting grooves 18. At this time, the annular slide plate 2 and the annular base plate 11 will be stored on the outer side of the device body 1, and can be pressed by the slider 14. The first spring 12 installed on the outside of the support slide rod 15 is used to pull the limiting rod 21 outward, so that one end of the limiting rod 21 is pulled out of the fixed groove 19. At this time, the resistance of the insertion rod 13 disappears. The compressed first spring 12 can pop out the annular slide plate 2 and the annular base plate 11, thereby supporting the bottom of the device body 1 to test the material. Since the bottom of the annular base plate 11 is equipped with a rubber anti-slip pad 10 at equal intervals, the rubber anti-slip pad 10 can further improve the anti-slip performance of the bottom of the annular base plate 11 and avoid positional displacement during use. When in use, the water storage bottle 16 is inserted into the water inlet 3. Water can be sprayed onto the surface of the material through the water mist nozzle 9. The water repellency of the material surface can be observed through the camera 8.

[0027] Working principle: In use, insert the water storage bottle 16 into the water inlet 3, then pull the limiting rod 21 outwards, causing one end of the limiting rod 21 to be pulled out of the fixing groove 19. At this time, the resistance experienced by the insertion rod 13 disappears, and the compressed first spring 12 can pop out the annular sliding plate 2 and the annular base plate 11, thereby supporting the bottom of the device body 1 to test the material. Then, place the bottom of the device body 1 against the area to be tested. Water can be sprayed onto the surface of the material through the water mist nozzle 9, and the camera 8 can take pictures of the water repellency of the material surface. After use, the annular sliding plate 2 and the annular base plate 11 are moved along the outside of the device body 1. The device slides upwards, causing the insert rods 13 installed on both sides of the top of the annular slide plate 2 to be inserted into the limiting grooves 18 at the bottom of the limiting blocks 17 installed on both sides of the main body 1. When the insert rods 13 are inserted into the limiting grooves 18, they will squeeze the limiting rod 21, causing one end of the limiting rod 21 to retract and compress the second spring 20. When the top of the insert rod 13 is fully inserted into the limiting groove 18, the second spring 20 will rebound, causing one end of the limiting rod 21 to be inserted into the fixing groove 19, fixing the insert rod 13 inside the limiting groove 18. At this time, the annular slide plate 2 and the annular base plate 11 will be stored on the outside of the main body 1, and the entire device can be easily carried by the operator through the handle 4.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
