DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0026] Example 1: A waterproof coating permeability testing device, see Figure 1 and Figure 2 As shown, it includes a support frame 1, a positioning frame 2 and a test barrel 3, the positioning frame 2 is arranged on the top of the support frame 1, the test barrel 3 is installed on the support frame 1 close to the positioning frame 2 by bolt connection, a plurality of first liquid outlet holes 4 are provided at the bottom of the test barrel 3, and also includes a support barrel 5, a detection disk 6, a liquid guide cover 601 and an observation plate 7, the support barrel 5 is rotatably arranged on the lower part of the support frame 1, the detection disk 6 is installed on the side of the support barrel 5 close to the test barrel 3 by bolt connection, a plurality of second liquid outlet holes 602 are provided on the detection disk 6, two of the liquid guide covers 601 are fixedly connected to the side of the support barrel 5 close to the detection disk 6 by welding, and the observation plate 7 is slidably connected between the two liquid guide covers 601.

[0027] When it is necessary to conduct a permeability test on the waterproof coating, the staff uses a brush to brush the waterproof coating on the bottom of the test barrel 3. After the waterproof coating on the bottom of the test barrel 3 is air-dried to form a film, the support barrel 5 is rotated to align the first liquid outlet 4 and the second liquid outlet 602. Then, an appropriate amount of water is added to the test barrel 3 to observe whether water droplets or watermarks appear on the observation plate 7. If the water in the test barrel 3 seeps through the waterproof coating film and then drips onto the observation plate 7 through the first liquid outlet 4 and the second liquid outlet 602, causing water droplets or watermarks to appear on the observation plate 7, it means that the waterproof performance of the waterproof coating is not good. If the observation plate 7 remains dry throughout the test, it means that the waterproof performance of the waterproof coating is good, thereby achieving the purpose of intuitively testing the waterproof performance of the waterproof coating. After the test is completed, the observation plate 7 is slid forward and taken out, and then the observation plate 7 is wiped and cleaned. After cleaning, the observation plate 7 is slid backward to reset.

[0028] Example 2: Based on Example 1, refer to Figure 3As shown, it also includes a mounting frame 8, a dual-axis motor 9, a mounting rod 10 and a brush plate 11. The mounting frame 8 is fixed to the positioning frame 2 by welding, and the dual-axis motor 9 is installed on the mounting frame 8 by bolt connection. The lower end of the output shaft of the dual-axis motor 9 is connected to the mounting rod 10 through a coupling, and the brush plate 11 is provided at one end of the mounting rod 10 away from the dual-axis motor 9. The brush plate 11 rotates in the test barrel 3. The brush plate 11 is made of nylon and has good corrosion resistance and wear resistance, so that the brush plate 11 can be used for a long time.

[0029] When the waterproof coating is subjected to a permeability test, the staff pours the waterproof coating into the test barrel 3, and then starts the dual-axis motor 9, and drives the mounting rod 10 to rotate through the output shaft of the dual-axis motor 9, and the mounting rod 10 drives the brush plate 11 to rotate to automatically brush the waterproof coating in the test barrel 3 flat, without the need for manual brushing by the staff. When the waterproof coating at the bottom of the test barrel 3 is brushed flat, the dual-axis motor 9 is turned off.

[0030] See also Figure 4-Figure 6 As shown, it also includes a guide rail 12, a sliding rod 13, a mounting shell 14, a fan 15, a push plate 16, an elastic member 17 and a deflector 18. The support barrel 5 is installed with four guide rails 12 by bolt connection. The sliding rod 13 is slidably arranged on the guide rail 12. The mounting shell 14 is fixed to the sliding rod 13 by welding. The fan 15 is installed in the mounting shell 14 by bolt connection. The elastic member 17 is connected between the sliding rod 13 and the guide rail 12. The side of the support frame 1 adjacent to the test barrel 3 is fixed. Four push plates 16 are connected, and the push plates 16 are inclined. The push plates 16 are in sliding contact with the sliding rod 13. The air deflector 18 is installed on the outside of the test barrel 3 by bolt connection. Four air inlets corresponding to the fans 15 are opened on the air deflector 18. The air outlet holes 19 corresponding to the number of the fans 15 are opened on the air deflector 18 and the test barrel 3. The isolation net 27 is installed on the side of the mounting shell 14 away from the guide rail 12. The isolation net 27 isolates and protects the air inlet to prevent debris from falling on the waterproof coating through the air deflector 18.

[0031] When the waterproof coating is applied, the staff rotates the support barrel 5, and the support barrel 5 drives the guide rail 12 and the sliding rod 13 to rotate. The sliding rod 13 contacts the push plate 16, so that the push plate 16 squeezes the sliding rod 13 and drives the mounting shell and the fan 15 to slide upward along the guide rail 12. The sliding rod 13 stretches the elastic member 17 to deform. When the push plate 16 squeezes the sliding rod 13 and slides upward along the guide rail 12 to the highest point, the sliding rod 13 stops sliding upward. At this time, the fan 15 is aligned with the air inlet of the air guide cover 18, and the fan 15 is started again to allow the fan 15 to air-dry the waterproof coating applied to the bottom of the test barrel 3, thereby shortening the time for the waterproof coating to dry and form a film, and improving the efficiency of the waterproof performance test of the waterproof coating. When the waterproof performance test of the waterproof coating is completed, the support barrel 5 is rotated in the opposite direction, and the elastic member 17 is reset to drive the sliding rod 13, the mounting shell and the fan 15 to slide downward and reset along the guide rail 12, and then the fan 15 is turned off.

The right side of the support frame 1 is fixedly connected to the fixing frame 20 by welding, the storage barrel 21 is installed on the fixing frame 20 by bolt connection, the top of the storage barrel 21 is provided with the protective cover plate 22, the storage barrel 21 is installed with the infusion tube 23 that penetrates the protective cover plate 22, and the infusion tube 23 that penetrates the protective cover plate 22 is installed on the storage barrel 21. The upper end of the tube 23 is connected to and communicated with the positioning frame 2. The spiral feeding rod 24 is rotatably arranged on the infusion tube 23. The other end of the dual-axis motor 9 is connected to the connecting shaft 25 through a coupling. The spiral feeding rod 24 and the connecting shaft 25 are commonly connected to the pulley transmission assembly 26. The pulley transmission assembly 26 consists of two pulleys and a flat belt. The feeding rod 24 and the connecting shaft 25 are both equipped with pulleys, and a flat belt is wound between the two pulleys.

[0033] Initially, the staff first slides the protective cover 22 upwards to open the storage barrel 21, and then adds an appropriate amount of waterproof coating into the storage barrel 21. During the test, the staff starts the dual-axis motor 9, and the output shaft of the dual-axis motor 9 drives the spiral feeding rod 24 to rotate through the pulley transmission assembly 26, so that the spiral feeding rod 24 rotates to transport the waterproof coating in the storage barrel 21 along the infusion tube 23 to the test barrel 3, thereby achieving the purpose of automatically feeding the waterproof coating.
