Description

[0002] The salt fog test machine is used for detecting the reliability of the measured sample by continuously spraying salt fog on the measured sample and shortening the corrosion period of the measured sample.

[0039] Specifically, when the staff starts the motor 8, the motor 8 will control the large gear 104 to rotate after starting, the large gear 104 rotating will drive the gear three 102 to rotate synchronously, and then the threaded rod 103 will rotate, the threaded rod 103 rotating will drive the supporting plate 901 and the partition plate 404 to move upwards synchronously, the rotation of the large gear 104 driven by the motor 8 will make the threaded rod 103 rotate, and the rotating assembly 9 and the partition plate 404 can move upwards and downwards simultaneously, thereby separating the reaction area in the salt spray tester from the feeding and discharging area, and reducing the influence of external factors on the experimental environment, and at the same time, the stability of the experimental environment can be ensured.

[0040] Please refer to Figure 9, Figure 10 and Figure 11, a plurality of scrapers 403 are slidably connected inside the observation window 4, a connecting plate 402 is fixedly connected to the inner side of each scraper 403, a rotating ring 401 is fixedly connected to an end of the connecting plate 402 away from the collection pool 2, the rotating ring 401 is rotatably connected with the box 7 at an end away from the collection pool 2, a gear ring is arranged on the inner side of the rotating ring 401, the inner side of the gear ring is engaged with the gear two 918, a partition plate 404 is rotatably connected to an end of the scraper 403 away from the rotating ring 401, the partition plate 404 is threadedly connected with the threaded rod 103, the test area in the salt spray tester can be reduced by the partition plate 404, thereby reducing energy consumption, by arranging the scraper 403, the gear two 918 can drive the scraper 403 to rotate synchronously when rotating, and then the scraper 403 can scrape the observation window 4 from the inside, reducing the water droplets attached to the observation window 4, and ensuring that the staff can observe the internal situation of the salt spray tester through the observation window 4.

[0046] Referring to FIG. 8, FIG. 9 and FIG. 10, the inner part of the protection plate 5 is provided with a flow groove 501, which is connected with the bottom plate 6 at the end far away from the motor 8. Through the flow groove 501, the water scraped by the scraper 403 can be guided to the bottom plate 6 for recycling, and the normal observation of the observation window 4 can be ensured.

[0047] The working principle of the present application is as follows: the staff manually moves the clamping block 924 upward, then places the material on the clamping assembly 908, loosens the clamping block 924, and the clamping block 924 moves towards the material under the elastic force of the spring 925, so that the clamping block 924 cooperates with the clamping assembly 908 to clamp the material. When the material is clamped, the isolation door 1 is closed, and the motor 8 is started. After the motor 8 is started, it controls the rotation of the large gear 104, and the rotation of the large gear 104 drives the synchronous rotation of the gear three 102, so that the threaded rod 103 rotates, and the support plate 901 and the partition plate 404 move upward synchronously. When the support plate 901 moves to the position where the hollow tube 915 contacts the salt mist treatment box 916, the motor 8 stops running.

At the same time, the air pump in the hollow tube 915 sucks the salt mist in the salt mist treatment box 916 into the inside of the connecting column 905, and then sprays it out through the nozzle 907 outside the connecting column 905. The fan 906 at the upper end of the connecting rod one 912 releases wind power, so that the salt mist flows quickly in the salt mist test machine, and the salt mist is distributed more uniformly. At the same time, the gear one 917 rotates to drive the gear two 918 to rotate through the belt, and the gear two 918 rotates to drive the rotating ring 401 to rotate through the gear ring, and the rotating ring 401 rotates to drive the connecting plate 402 to rotate synchronously, and the connecting plate 402 rotates to drive the scraper 403 to rotate, so that the inner wall of the observation window 4 is scraped through the rotation of the scraper 403, reducing the influence of water droplets generated during the operation of the salt mist test machine on the observation window 4, so that the staff can observe the internal situation of the salt mist test machine through the observation window 4 at any time. The water scraped off flows to the collection tank 2 through the flow groove 501, and when a certain amount of liquid is collected in the collection tank 2, it is discharged through the discharge pipe 3.
