Description

Technical Field

[0001] This utility model relates to the field of fluid contamination testing technology, and in particular to a fluid contamination generating device. Background Technology

[0002] Fluid contamination generators are used in industries such as aviation, aerospace, shipbuilding, weaponry, electrical engineering, electronics, automobiles, motorcycles, and communications to determine the reliability of electrical and electronic products, instruments, or other equipment during transportation, storage, and use.

[0003] When conducting tests, existing equipment requires applying fluid to the test specimens. Since different test specimens vary in size, it is easy to create blind spots in the application. In addition, after the test, a large amount of fluid remains on the test platform used to place the test specimens. If not cleaned in time, the fluid residue or solidification will be difficult to clean later. Utility Model Content

[0004] The present invention addresses the problem of providing a fluid contamination generating device, which solves the technical problem that existing devices require applying fluid to test pieces during testing. Different test pieces have different sizes, which can easily lead to application dead zones. In addition, after the test, a large amount of fluid remains on the test platform used to place the test pieces. If not cleaned in time, the fluid residue or solidification will lead to difficulties in subsequent cleaning.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fluid contamination generating device includes a test chamber, a test chamber door, a base, and a platform. The test chamber door is installed on the test chamber, the base is installed inside the test chamber, the platform is installed on the base, a top plate is installed on the top side inside the test chamber, a toothed ring is rotatably installed on the bottom side of the top plate, and a scraping mechanism and a spraying mechanism are installed on the bottom side of the toothed ring.

[0007] Preferably, the base is provided with a discharge trough, and a drain valve corresponding to the discharge trough is installed on the outside of the test chamber.

[0008] Preferably, the top plate and the gear ring are connected by a bearing, a second motor is mounted on the top plate, and a rotating tooth is mounted on the output end of the second motor, and the rotating tooth meshes with the gear ring.

[0009] Preferably, the scraping mechanism includes a base scraper mounted on the bottom side of the toothed ring, a first motor mounted on the side wall of the base scraper, and a rotary table scraper mounted on the output end of the first motor.

[0010] Preferably, the spraying mechanism includes a lifting frame installed on the bottom side of the toothed ring, a threaded rod rotatably installed inside the lifting frame, a lifting platform threadedly connected to the threaded rod installed on the lifting frame, and a nozzle installed on the lifting platform.

[0011] Preferably, a third motor is installed on the lifting frame, and the output end of the third motor is connected to the threaded rod.

[0012] The beneficial effects of this utility model are: the rotation of the gear ring is achieved by the operation of the second motor, which drives the scraping mechanism and the spraying mechanism to rotate around the platform. During the rotation of the spraying mechanism, the third motor works, and the lifting platform is raised and lowered on the lifting frame, and the fluid is evenly sprayed onto the test piece through the nozzle.

[0013] When the scraping mechanism rotates, the rotating table scraper is rotated by the first motor. During the fluid test, the rotating table scraper rotates to overlap with the base scraper to avoid affecting the test piece on the platform. After the test is completed, the rotating table scraper rotates to match the platform. As the scraping mechanism rotates, the fluid on the base is scraped off by the base scraper, and the fluid on the platform is scraped off by the rotating table scraper. The fluid is collected in the unloading trough and discharged through the drain valve to clean up the residual fluid. Attached Figure Description

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Specific implementation examples are given below.

[0022] See Figures 1-4 A fluid contamination generating device includes a test chamber 1, a test chamber door 2, a base 3, and a platform 4. The test chamber door 2 is installed on the test chamber 1, the base 3 is installed inside the test chamber 1, the platform 4 is installed on the base 3, a top plate 6 is installed on the top side inside the test chamber 1, a toothed ring 7 is rotatably installed on the bottom side of the top plate 6, and a scraping mechanism and a spraying mechanism are installed on the bottom side of the toothed ring 7.

[0023] The base 3 has a discharge trough 5, and the outside of the test chamber 1 is equipped with a drain valve 15 corresponding to the discharge trough 5. The fluid is collected in the discharge trough 5 and discharged through the drain valve 15.

[0024] The top plate 6 and the gear ring 7 are connected by bearings. A second motor 16 is mounted on the top plate 6, and a rotating gear 17 is mounted on the output end of the second motor 16, meshing with the gear ring 7. The scraping mechanism includes a base scraper 8 mounted on the bottom side of the gear ring 7, a first motor 10 mounted on the side wall of the base scraper 8, and a rotary table scraper 9 mounted on the output end of the first motor 10. The spraying mechanism includes a lifting frame 11 mounted on the bottom side of the gear ring 7, a threaded rod 12 rotatably mounted inside the lifting frame 11, a lifting platform 13 threadedly connected to the threaded rod 12 mounted on the lifting frame 11, and a nozzle 14 mounted on the lifting platform 13. A third motor 18 is mounted on the lifting frame 11, and the output end of the third motor 18 is connected to the threaded rod 12. The rotation of the gear ring 7 is achieved by the operation of the second motor 16, driving... The scraping mechanism and the spraying mechanism rotate around the platform 4. During the rotation of the spraying mechanism, the third motor 18 works, and the lifting platform 13 rises and falls on the lifting frame 11. The fluid is evenly sprayed onto the test piece through the nozzle 14. When the scraping mechanism rotates, the first motor 10 realizes the rotation of the rotating platform scraper 9. During the fluid test, the rotating platform scraper 9 rotates to overlap with the base scraper 8 to avoid affecting the test piece on the platform 4. After the test is completed, the rotating platform scraper 9 rotates to fit the platform 4. As the scraping mechanism rotates, the fluid on the base 3 is scraped off by the base scraper 8 and the fluid on the platform 4 is scraped off by the rotating platform scraper 9. The fluid is collected in the unloading trough 5 and discharged through the drain valve 15 to clean up the residual fluid.

[0025] Working principle: Open the test chamber door 2 and place the test piece on the platform 4. At this time, the rotating table scraper 9 rotates and coincides with the base scraper 8. Close the test chamber door 2. The second motor 16 drives the rotating gear 17 to rotate, which in turn drives the meshing gear ring 7 to rotate. This causes the scraping mechanism and the spraying mechanism to rotate around the platform 4. During the rotation, the third motor 18 drives the threaded rod 12 to rotate, which in turn drives the threaded lifting platform 13 to rise and fall on the lifting frame 11, thereby adjusting the height of the nozzle 14. The nozzle 14 then sprays the fluid evenly onto the test piece to detect the contamination effect of the fluid on the test piece. After the test is completed, the test piece is removed. At this time, the first motor 10 drives the rotating table scraper 9 to rotate to match the platform 4. As the scraping mechanism rotates, the base scraper 8 scrapes the fluid off the base 3, and the rotating table scraper 9 scrapes the fluid off the platform 4. The fluid collects in the unloading trough 5 and is discharged through the drain valve 15.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
