[0024] The input end of the control host 14 is electrically connected to the output end of the No. 1 motor 7, and the output end of the control host 14 is signal-connected to the input end of the display 15; by setting the control host 14, when conducting a wind power control experiment, the rotating seat 9 is moved to the inside of the air outlet and the control host 14 and the display 15 are started, so that the air can drive the No. 1 motor 7 to rotate rapidly through the fan blades 13.

[0027] The spring 16 is located directly below the lifting column 3, and the spring 16 is fixedly connected to the bottom of the inner cavity of the support sleeve 2; by setting the spring 16, when the height of the lifting column 3 is adjusted, the spring 16 can push the lifting column 3, so that the lifting column 3 can be lifted from the inside of the support sleeve 2, thereby facilitating the movement of the lifting column 3.

[0031] The working principle of the double-fed wind turbine scale-down control experimental equipment provided by the utility model is as follows:

[0032] Step 1: First, when conducting a wind power control experiment, move the rotating seat 9 to the inside of the air outlet and start the control host 14 and the display 15, so that the air can drive the No. 1 motor 7 to rotate quickly through the fan blades 13. At this time, the control host 14 can detect the current generated when the No. 1 motor 7 rotates, and then display it intuitively through the display 15, so as to achieve the wind power conversion effect, thereby avoiding the problem that the real wind turbine structure is too large and not suitable for teaching use, thereby bringing convenience to wind power experimental teaching. When the No. 1 motor 7 rotates for a long time and generates more heat, the heat conducting plate 8 can absorb the heat on the surface of the No. 1 motor 7, and then The heat is conducted to the outside of the protective cover 6, thereby improving the heat dissipation speed of the No. 1 motor 7, that is, improving the stability of the No. 1 motor 7 when working for a long time.

[0033] Step 2: When it is necessary to adjust the height of the fan blade 13, rotate the bolt 171 so that the bolt 171 can be moved out from the inside of the lifting column 3. At this time, the lifting column 3 can move up and down inside the support sleeve 2, that is, drive the No. 1 motor 7 to move up and down, thereby facilitating the height adjustment of the fan blade 13. When it is necessary to adjust the direction of the rotating seat 9, start the No. 3 motor 181 so that the No. 3 motor 181 can drive the No. 1 gear 5 to rotate through the No. 2 gear 182, that is, drive the protective cover 6 to rotate, thereby achieving the effect of adjusting the direction of the rotating seat 9. When the experimental equipment is moved and transported, the support table 1 is pushed so that the sliding wheel 192 can drive the support table 1 to move horizontally through the support column 191, that is, drive the control host 14 and the display 15 to move horizontally, thereby achieving the mobile transportation effect of the experimental equipment, thereby facilitating the adjustment of the working position of the experimental equipment.
