[0002] Parts of a vacuum toilet (such as pipes, valves, connectors, etc.) may be exposed to humid, salty or acidic environments during train operation, and these conditions can cause corrosion and damage to the parts. Spray testing helps verify the corrosion resistance of these parts by accelerating the corrosion process, ensuring that they do not fail due to corrosion during long-term use:

[0003] In actual use, parts may be eroded by corrosive substances from different directions. The nozzle that cannot adjust the angle limits the simulation of these complex working conditions during the test, and the test results may not accurately reflect the performance of the parts in the actual environment.

[0020] In order to more clearly illustrate the overall concept of the present invention, the following will be described in detail by way of examples in conjunction with the drawings of the specification.

[0021] As Figures 1 to 4 shown, an embodiment of the present invention provides a test bench for components of a unified vacuum toilet for rail transit passenger cars, including a test bench 1:

[0022] An auxiliary slide rail 2 is fixedly provided at the edge of the top end of the test bench 1. The side wall of the auxiliary slide rail 2 is slidably connected to one side of the support table 5. The top end of the support table 5 is inserted and connected to the bottom end of the U-shaped bracket 6. A groove 7 is provided on one side of the top end of the U-shaped bracket 6. The two sides of the inner wall of the groove 7 are hinged to the bottoms of the two sides of the side frame 8. The top end of the side frame 8 is fixedly connected to the middle position of the top end of the arc-shaped track frame 10 through an arc-shaped frame 9. An arc-shaped slide plate 11 is slidably arranged inside the arc-shaped track frame 10. The back of the arc-shaped slide plate 11 is rotationally connected to the top of one side of the rotating plate 13 through a connecting shaft 17. A spray tube 12 is fixedly provided on the front of the arc-shaped slide plate 11. One end of the spray tube 12 is communicated with a nozzle 14.

[0023] Specifically, the other side of the support table 5 is fixedly connected to the outer wall of the annular internal gear ring 3. The annular internal gear ring 3 is rotatably connected to the top end of the test bench 1. The annular internal gear ring 3 meshes with the gear 4.

[0024] Specifically, an internal groove is provided on one side of the test bench 1. A driving motor 16 is fixedly arranged inside the internal groove. The output end of the driving motor 16 is fixedly connected to the bottom end of the gear 4.

[0025] Specifically, a servo motor 15 is fixedly provided at the bottom end of the U-shaped bracket 6. The output end of the servo motor 15 is fixedly connected to the bottom of the other side of the rotating plate 13.

[0026] Specifically, a switch panel is fixedly provided on the side wall of the test bench 1. A driving motor switch and a servo motor switch are respectively fixedly provided on the surface of the switch panel. The driving motor 16 and the servo motor 15 are respectively electrically connected to an external power supply through the driving motor switch and the servo motor switch.

[0027] Working principle: First, turn on the switch of the driving motor. The output end of the driving motor 16 drives the gear 4 to rotate. The gear 4 meshes with the annular internal gear ring 3, and the annular internal gear ring 3 is rotatably arranged on the test bench 1. Therefore, it can drive the support platform 5 at one end of the annular internal gear ring 3 to rotate along the side wall of the auxiliary slide rail 2. After adjusting to the predetermined test position, then turn on the switch of the servo motor. The output end of the servo motor 15 drives the rotating plate 13 to rotate. The top on one side of the rotating plate 13 is rotatably arranged with the arc-shaped slide plate 11 inside the arc-shaped track frame 10 through the connecting shaft 17, which will drive the arc-shaped slide plate 11 to slide back and forth on the arc-shaped track frame 10. When the arc-shaped slide plate 11 moves to one end of the arc-shaped track frame 10, at this time, the entire arc-shaped track frame 10 will tilt downward or upward around the slot 7 as the axis. Therefore, the angle of the nozzle 14 can be adjusted at multiple angles to perform spray tests on the components of the vacuum toilet.
