[0027] 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.

[0028] Reference Figure 1-Figure 3 , the utility model provides an embodiment: a test platform for an energy storage converter, including a test platform 1 for loading test, the inner wall of the top of the test platform 1 is fixedly connected to a rotating platform 4, the front end of the rotating platform 4 is rotatably connected to a bidirectional screw 8, the front and rear ends of the outer wall of the bidirectional screw 8 are both threadedly connected to a moving block 13, the opposite end of the moving block 13 is rotatably connected to a traction plate 14, the bottom end of the rotating plate 9 is rotatably connected to the opposite end of the traction plate 14, the left and right ends of the rotating plate 9 are fixedly connected to a connecting plate 10, a worm 11 is fixedly connected to the inner wall of the left end connecting plate 10, the left end of the clamping platform 15 passes through the right end of the left end connecting plate 10 and is fixedly connected to a worm gear 12, the worm gear 12 and the worm gear 11 are meshedly connected, and the bottom end of the inner wall of the clamping platform 15 is fixedly connected to an electric retraction rod 16, refer to Figure 4 The driving end of the electric retraction rod 16 is fixedly connected to the connecting platform 17. The left and right ends of the connecting platform 17 are rotatably connected to the retraction plate 18. The opposite ends of the retraction plate 18 are rotatably connected to the clamping plate 19. The outer wall of the opposite end of the retraction plate 18 is rotatably connected to the inner walls of the left and right ends of the clamping platform 15.

[0029] Specifically: after the fixing frame 7 is docked and placed on the clamping platform 15, the connecting frame 20 is pressed again, so that the deflection column 22 rotates again along the slide wheel 21, so that the bottom side of the deflection column 22 falls off from the fixing frame 7, and then the clamping claw 25 is released from the converter. At this time, the electric retraction rod 16 is started, so that the connecting platform 17 drives the retraction plate 18 to retract inward, so that the clamping plate 19 clamps the converter, ensuring that the converter is firmly fixed during testing. In order to achieve multi-angle adjustment of the converter, the two-way screw 8 can be rotated to make the moving block 13 pull the traction plate 14, so that the rotating plate 9 is deflected, and then the plane direction of the converter at the clamping platform 15 is adjusted. At the same time, the worm 11 is rotated to make the worm 11 drive the worm gear 12 to rotate, so that the worm gear 12 drives the clamping platform 15 to adjust the elevation angle, which is convenient for the device to perform plane steering and elevation adjustment during the converter testing process, ensuring the comprehensiveness and accuracy of the test.

[0030] Reference Figure 5 and Figure 6, the steering column 2 is used for lifting and hoisting, and the bottom end of the steering column 2 is rotatably connected to the right side of the top of the testing platform 1. The top of the steering column 2 is fixedly connected to a lifting frame 3, and the top of the lifting frame 3 is fixedly connected to an electric reel 5. The output end of the electric reel 5 is installed with a connecting rope 6, and the other end of the connecting rope 6 is fixedly connected to the outer wall of the top of the connecting frame 20. The bottom end of the connecting frame 20 is fixedly connected to a slide wheel 21, and the left and right ends of the slide wheel 21 are rotatably connected to the guide plates 23, and the opposite ends of the guide plates 23 are rotatably connected to the focusing plates 24. The opposite ends of the focusing plates 24 are fixedly connected to the clamping claws 25, and the inner walls of the opposite ends of the clamping claws 25 are rotatably connected to the left and right ends of the fixed frame 7 respectively. The inner wall of the slide wheel 21 is provided with a deflection column 22, and the bottom end of the deflection column 22 is tightly attached to the top of the fixed frame 7. The outer wall of the connecting frame 20 is slidably connected to the inner wall of the fixed frame 7.

[0031] Specifically, when the steering column 2 needs to be turned toward the converter to be tested, the connecting rope 6 can be lowered by operating the electric reel 5 so that the fixing frame 7 can be attached to the surface of the converter. At this time, the connecting frame 20 naturally lowers due to the loss of the lifting force of the connecting rope 6, and finally stops at the bottom of the fixed frame 7. As the connecting frame 20 is lowered, the sliding groove wheel 21 will be pressed down, causing the deflection column 22 at the sliding groove wheel 21 to produce a 90-degree deflection along the shape of the inner side of the sliding groove wheel 21. This deflection enables the bottom side of the deflection column 22 to be firmly stuck in the fixed frame 7, thereby maintaining the displacement stability of the connecting frame 20 at the fixed frame 7. When the connecting frame 20 is displaced, the guide plate 23 connected to the sliding groove wheel 21 will drive the convergence plate 24 to retract inward, and then the clamping claw 25 will retract inward, thereby firmly clamping the converter, making it convenient to lift and move it. Through this series of mechanical actions, it is ensured that the converter can be safely and stably fixed and lifted during the detection process, thereby improving the efficiency and safety of the detection.

[0032] Working principle: When the steering column 2 is turned toward the converter to be tested, the electric reel 5 lowers the connecting rope 6, allowing the fixed frame 7 to fit against the converter. After the connecting frame 20 loses the lifting force of the connecting rope 6, the connecting frame 20 is lowered to the bottom side of the fixed frame 7, causing the chute wheel 21 at the connecting frame 20 to press down, causing the deflection column 22 at the chute wheel 21 to deflect 90 degrees along the inner shape of the chute wheel 21, so that the bottom side of the deflection column 22 is stuck in the fixed frame 7, thereby maintaining the displacement of the connecting frame 20 at the fixed frame 7. When the connecting frame 20 is displaced, the guide plate 23 connected to the chute wheel 21 causes the convergence plate 24 to drive the clamping claw 25 to retract inward, so that the clamping claw 25 fixes the converter, making it easier to lift the converter, and after the fixed frame 7 is docked and placed on the clamping platform 15 , press the connecting frame 20 again to make the deflection column 22 rotate again along the slide wheel 21, so that the bottom side of the deflection column 22 falls off from the fixed frame 7, thereby releasing the clamping claw 25 from the converter, and starting the electric retraction rod 16 to make the connecting platform 17 drive the retraction plate 18 to retract the clamping plate 19 inward, so that the clamping plate 19 clamps the converter, so that the converter is fixed during detection, and rotating the bidirectional screw 8 to make the moving block 13 pull the traction plate 14 to deflect the rotating plate 9, thereby adjusting the plane direction of the converter at the clamping platform 15, and rotating the worm 11 to start the worm gear 12 to rotate, so that the worm gear 12 drives the clamping platform 15 to adjust the elevation angle, so that the converter can perform plane steering and elevation adjustment during the detection process.
