[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0021] Combine Figure 1 A water resistance testing device for an emulsion polymer water resistance agent includes a test barrel 1, an upper end of the test barrel 1 is fixedly connected to a motor 2, and an output end of the motor 2 is fixedly connected to a rotating shaft 21.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Example 1:

[0024] See also Figure 1 and Figure 3 The outer surface of the rotating shaft 21 is fixedly connected to a gear A22, and two groups of gears A22 are fixedly connected. The inner wall of the test barrel 1 is fixedly connected to a support rod 3, and one side of the support rod 3 is rotatably connected to a fixed rod 31. One side of the fixed rod 31 is fixedly connected to a gear B32, one group of gears A22 is meshed with the gear B32, and one side of the gear B32 is meshed with a tooth block 42. There are multiple groups of tooth blocks 42 fixedly connected, and one side of the multiple groups of tooth blocks 42 is fixedly connected to a movable plate 4, and one side of the movable plate 4 is fixedly connected to a scraper 41.

[0025] Specifically, when it is necessary to clean the inner wall of the side of the test barrel 1, the movable plate 4 is placed into the test barrel 1. At this time, the gear B32 is engaged with the tooth block 42, and the motor 2 drives the rotating shaft 21 to rotate. At this time, the gear A22 rotates, driving the engaged gear B32 to rotate, so that the engaged tooth block 42 is moved downward, so that the scraper 41 can contact the inner wall of the test barrel 1 for cleaning, thereby realizing the cleaning process of the test barrel 1 and reducing the residual residue.

[0026] Example 2:

[0027] See also Figure 1-Figure 3 The upper surface of the test barrel 1 is provided with a feed port 11 and a scraper groove 12, the outer surface of the rotating shaft 21 is covered with a baffle 14, the scraper 41 extends into the interior of the test barrel 1 through the scraper groove 12, and a moving port 13 is provided on one side of the baffle 14. The movable plate 4 extends into the interior of the test barrel 1 through the moving port 13. The rotating shaft 21 is fixedly connected to the rotating rod 23 on both sides, and the rotating rod 23 is fixedly connected to multiple groups. One side of the support rod 3 is rotatably connected to the mounting rod 5, and one side of the mounting rod 5 is fixedly connected to the gear C51.

[0028] Specifically, the emulsion polymer enters the test barrel 1 through the feed port 11. When testing is required, water also enters from the feed port 11 for testing. The baffle 14 can prevent liquid splashing. When cleaning is required, the movable plate 4 extends from the movable port 13 to the inside of the test barrel 1, and the scraper 41 extends from the scraper groove 12 into the inside of the test barrel 1 to clean the inner wall. The motor 2 drives the rotating shaft 21 to rotate, so that the rotating rod 23 rotates to stir and mix, thereby accelerating the test reaction time. The rotating shaft 21 rotates, and at this time another set of gears A22 rotates, driving the meshing gear C51 to rotate, thereby driving the fixed shaft 52 to rotate. The fixed shaft 52 moves in the slot in the moving block 53, and moves up and down with the moving block 53, so that the circular brush 54 can clean the bottom surface of the test barrel 1.
