[0024] See also Figures 1-4 , the utility model provides a technical solution:

[0025] Embodiment 1: A high and low speed adjustable wind tunnel controller includes a control unit 1 for controlling a wind tunnel motor, including a control main board 108 for regulating and controlling the DC voltage, both sides of the control main board 108 are fixedly connected with a power socket 101 for installing a power cord and a motor wire, one side of the power socket 101 is provided with a power port 102 for installing a power cord and a motor wire, the inner side of the power port 102 is fixedly connected with a power board 103 for transmitting current, the top of the power socket 101 is provided with a fuse 107 for monitoring the voltage, both sides of the top of the power socket 101 are provided with mounting grooves 104, the top of the mounting groove 104 is threadedly connected with an adjusting bolt 105 for adjusting a wire pressure plate 106, and the inner side of the power socket 101 is fixedly connected with a power pin 110 for connecting to the control main board 108.

[0026] Furthermore, power connection plates 109 for mounting power connection pins 110 are fixedly connected to both sides of the top of the control main board 108 , and the power connection plates 109 are fixedly connected to the power connection pins 110 .

[0027] Furthermore, the bottom end of the adjusting bolt 105 is movably connected to a wire pressing plate 106 for fixing the power line and the motor line, and the wire pressing plate 106 is movably connected to the inner side of the power port 102 .

[0028] Furthermore, the fuse 107 is made of lead-antimony alloy, and the fuse 107 is fixedly connected to the power pin 110 and the power board 103 respectively.

[0029] As can be seen from the above, when using a wind tunnel controller with adjustable high and low speeds, the staff inserts the power cord and the motor cord into the power ports 102 of the two power sockets 101 respectively, and then the staff rotates the adjusting bolt 105, and the adjusting bolt 105 drives the wire pressing plate 106 to press and fix the power cord and the motor cord.

[0030] Furthermore, when control is performed after installation, current is applied to the control main board 108 through the power cord, and then the debugging switch 205 is turned. The debugging switch 205 starts the control main board 108, and the control main board 108 controls the transmission of DC voltage. At this time, DC power enters the fuse 107 through the power pin 110 and is transmitted to the power board 103 through the fuse 107, thereby acting on the motor line and being transmitted to the motor. When transmitting DC power, if the voltage is too high and exceeds the limit that the fuse 107 can withstand, the fuse 107 will melt, thereby disconnecting the transmission of DC power.

[0031] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the installation unit 2 that plays a fixing and protective role includes a base plate 201 fixedly connected to the bottom of the power socket 101 for installation on the equipment, and a protective cover 203 that plays a protective role is fixedly connected to the top of the base plate 201, and a debugging switch 205 for adjusting the DC voltage is movably connected to the front of the protective cover 203.

[0035] As can be seen from the above, by turning the debug switch 205, the debug switch 205 starts the control main board 108, thereby controlling and regulating the current. When the control main board 108 generates heat during operation, the heat can be quickly dissipated through the heat dissipation port 206, and the control main board 108 can be protected by the protective cover 203 to prevent tools or objects from contacting the control main board 108.
