A wire connection port 4 and a test device 5 are provided on one side of test chamber 1. Two slide rails 6 are fixedly connected inside test chamber 1. A fixing plate 7 is installed on the slide rails 6. Two pairs of sliders are fixedly connected to the bottom of the fixing plate 7. Each pair of sliders is slidably connected to the slide rail 6 on the corresponding side. A humidification vibration mechanism is provided at the bottom of the test chamber 1. The wire connection port 4 can provide a channel for the connecting wires between the motor protection controller under test and the test device 5.

[0024] A main clamping plate 8 is fixedly connected to the fixed plate 7. A through groove is provided on the fixed plate 7, and a secondary clamping plate 9 is slidably connected in the through groove. A nut 10 is fixedly connected to the bottom of the secondary clamping plate 9. A lead screw 11 is rotatably connected to the bottom of the fixed plate 7. The nut 10 is threadedly connected to the lead screw 11. A servo motor 12 is provided at the bottom of the fixed plate 7. The output end of the servo motor 12 is coaxially fixedly connected to the lead screw 11. The servo motor 12 can drive the lead screw 11 to rotate. The nut 10 and the secondary clamping plate 9, which are threadedly connected to the lead screw 11, can move freely in the through groove, thereby cooperating with the main clamping plate 8 to clamp and fix the motor protection controller under test.

[0025] The humidification vibration mechanism includes a drive motor 13 fixedly connected to the bottom of the test chamber 1. A drain tank 14 is fixedly connected to the drive motor 13. A piston plate 15 is slidably connected inside the drain tank 14. A reciprocating threaded rod 16 is rotatably connected inside the drain tank 14, passing through the piston plate 15 and threadedly connected to it. The output end of the drive motor 13 passes through the drain tank 14 and is coaxially and fixedly connected to the reciprocating threaded rod 16.

The rotating shaft of the reciprocating threaded rod 16 passes through the top of the drain tank 14 and is coaxially and fixedly connected to the rotating disk 17. A connecting shaft 18 is rotatably connected to the rotating disk 17 away from the axis. One end of the rotating disk 17 is rotatably connected to the fixed plate 7. The drive motor 13 can drive the reciprocating threaded rod 16 to rotate. When the reciprocating threaded rod 16 rotates, the piston plate 15, which is threaded to it, will move along the axial direction of the reciprocating threaded rod 16, thereby discharging the water in the drain tank 14. The outlet of the drain tank 14 is connected to the atomizing nozzle 3, so that the atomizing nozzle 3 can spray atomized water. At the same time, the rotating disk 17 can also rotate synchronously.

[0028] The drive motor 13 can drive the reciprocating threaded rod 16 to rotate. When the reciprocating threaded rod 16 rotates, the piston plate 15, which is threaded to it, will move along the axial direction of the reciprocating threaded rod 16, thereby discharging the water in the drain tank 14. The outlet of the drain tank 14 is connected to the atomizing nozzle 3, so that the atomizing nozzle 3 can spray atomized water. At the same time, the rotating disk 17 can also rotate synchronously. The connecting shaft 18 on the rotating disk 17 will also drive the fixed plate 7 to move back and forth on the slide rail 6, thereby achieving a vibration effect. This can simulate the high humidity and vibration environment and conduct more stringent tests on the motor protection controller.
