The movable rod 6 is threadedly connected to the adjusting screw rod 5 through the threaded hole, which facilitates the movable rod 6 to adjust its position on the adjusting screw rod 5 through the threaded hole.

The electric push rod 10 is fixedly connected to the fixing plate 3 through the installation groove. A connecting rod 11 is fixedly installed on the output end of the electric push rod 10, and a mounting plate 12 is fixedly installed on the top of the connecting rod 11.

[0036] When using the detection platform of the photovoltaic water pump inverter, firstly, the controller 17 is used to start the dual-axis motor 4 to drive the adjusting screw 5 to rotate. The rotation of the adjusting screw 5 drives the movable rod 6 to move to the side away from the dual-axis motor 4. Then the staff will place the detection computer on the top of the placement seat 2, and place the photovoltaic water pump of the model to be detected on the top of the base 1. Then the dual-axis motor 4 is started again to drive the movable rod 6 outside the adjusting screw 5 to move, so that the movable plate 7 fixes the photovoltaic water pump. Then the detection data line is connected to the inverter body 9, and the liquid inlet pipe 15 is connected to the photovoltaic water pump, and the return liquid pipe 16 is also connected accordingly. Then the detection is started, and the height of the lighting lamp 13 is adjusted by the electric push rod 10 according to the detection needs, so that the light intensity meets different situations. During the detection process, the corresponding data is obtained by using the pumping work of the water pump, so that the staff can analyze, detect and judge the data.
