The first driving element is used for driving the first slider 670 to slide, so that the first guide plate 560 and the second guide plate 570 are both abutted against the inner wall of the first side wall 410; the second driving element is used for driving the second slider 710 to slide, so that the first guide plate 560 and the second guide plate 570 are both abutted against the inner wall of the second side wall 430.

The first electromagnet 690 is used for attracting the first slider 670, and when the first electromagnet 690 attracts the first slider 670, the first guide plate 560 abuts against the inner wall of the first sidewall 410, and the second guide plate 570 abuts against the inner wall of the first sidewall 410; the second electromagnet 730 is used for attracting the second slider 710, and when the second electromagnet 730 attracts the second slider 710, the first guide plate 560 abuts against the inner wall of the second sidewall 430, and the second guide plate 570 abuts against the inner wall of the second sidewall 430.

Through the above technical scheme, the guiding component can be adjusted according to different external wind directions, so that the rotation direction of the rotating shaft 140 is ensured to be unchanged all the time; specifically, if the current external wind direction is from the air inlet 250 to the air outlet 260, the controller stops the first electromagnet 690, and then starts the second electromagnet 730, so that the second electromagnet 730 attracts the second slider 710, and further drives the third cable 650 and the fourth cable 660 to move, and further drives the first guide plate 560 and the second guide plate 570 to rotate, and finally makes the first guide plate 560 and the second guide plate 570 abut against the second side wall 430 (as shown in fig. 5), at this moment, the wind direction in the pipeline is from left to right, so as to ensure that the rotating shaft 140 rotates in a reverse clock, and ensure that the rotating direction of the fan blade 150 is also in a reverse clock, so as to ensure that the driving internal air flows into the first channel 520.

When the wind speed sensor senses that the wind speed from left to right is reduced, it indicates that the external wind direction changes, and if the wind speed is reduced to a preset value (for example, 50% of the maximum wind speed value), it indicates that the external wind direction becomes the wind direction against the axial flow fan 510, that is, the wind is blown from the air outlet 260 to the air inlet 250, in this case, the flow of air in the inner pipeline 240 is blocked, the rotation speed of the rotating shaft 140 is reduced, and the rotation speed of the fan blade 150 is further reduced, so that heat dissipation is not facilitated; for this reason, the controller controls the axial flow fan 510 to reversely rotate, then stops the second electromagnet 730, and then starts the first electromagnet 690, so that the first electromagnet 690 attracts the first slider 670, and then drives the first cable 630 and the second cable 640 to move, and further drives the first guide plate 560 and the second guide plate 570 to rotate, and finally makes the first guide plate 560 and the second guide plate 570 abut against the first side wall 410, at this time, the wind direction in the pipeline is from right to left (i.e. the wind direction of the axial flow fan 510 becomes consistent with the external wind direction), in this case, the air in the inner pipeline 240 blows the baffle 450 close to the second side wall 430, and the rotating shaft 140 still rotates in reverse clock, so as to ensure that the rotation direction of the fan blade 150 is also in reverse clock, so as to ensure that the driving internal air flows into the first channel 520; that is, the rotation direction of the rotation shaft 140 is always ensured to be unchanged regardless of the external wind direction. Also, in this case, when the wind speed sensor senses that the wind speed decreases from right to left, it indicates that the external wind direction changes, if the wind speed decreases to a preset value (for example, 50% of the maximum wind speed value), the axial flow fan 510 can be controlled to reversely rotate again, the first electromagnet 690 is stopped, the second electromagnet 730 is started, and the rotation of the first baffle 450 and the second baffle 450 is realized again, which is not described again here.
