[0045] On rainy days, the humidity of the external air is relatively high. When the external air enters the mine, the humidity of the air inside the mine will increase, making the interior of the mine humid, reducing the air quality inside the mine, and increasing the chance of discomfort for the staff. At this time, the staff uses the controller to operate the No. 1 motor 54, and then drives the No. 1 connecting shaft 53 to rotate through the No. 1 transmission mechanism 55, and then drives the No. 1 connecting block 52 to move, and then drives the No. 1 sliding member 51 to move, and then drives the No. 1 ventilation tube 56 to move, so that the No. 1 ventilation tube 56 close to the No. 2 ventilation slot 511 moves toward the No. 1 connecting tube 13, and the shaft of the No. 1 ventilation tube 56 is rotated. When the axis of the first connecting tube 13 coincides with the first connecting tube 13, the first motor 54 of the controller stops working and the second exhaust fan 58 is operated, thereby increasing the suction force on the external air, and then the external humid air moves into the ventilation duct 12 through the first ventilation tube 56 and the first ventilation plate 57. When the humid air moves, the desiccant in the first containing chamber absorbs the moisture in the air, thereby reducing the humidity of the air entering the mine, thereby reducing the air humidity inside the mine, thereby improving the air quality in the mine, and thereby reducing the probability of discomfort for the staff; after the desiccant has been used for a period of time, the water absorption performance of the desiccant The water absorption quality is reduced. At this time, the staff uses the controller to make the No. 1 motor 54 work again, so that the No. 1 sliding member 51 moves again, and then the other No. 1 ventilation tube 56 moves toward the No. 1 connecting tube 13. When the axis of the other No. 1 ventilation tube 56 coincides with the axis of the No. 1 connecting tube 13, the controller stops the No. 1 motor 54, so that the moisture in the humid air continues to be absorbed. At the same time, the controller makes the conductive mechanism 59 and the switch of the heating power supply close to the No. 1 ventilation tube 56 (the No. 1 ventilation tube 56 whose axis does not coincide with the axis of the No. 1 connecting tube 13) work, so that the No. 1 ventilation tube 56 The heating wire in the wind tube 56 works, thereby baking the desiccant in the No. 1 ventilation tube 56, thereby restoring the water absorption performance of the desiccant, and then making the desiccant in the two No. 1 ventilation tubes 56 absorb moisture in the humid air alternately, and then continuously absorb moisture in the humid air, thereby improving the dehumidification quality of the ventilation device; when it is sunny outside, the staff operates the No. 1 motor 54 through the controller, thereby moving the No. 1 sliding member 51, thereby making the No. 2 ventilation slot 511 coincide with the axis of the No. 1 connecting tube 13, thereby allowing the outside air to directly enter the ventilation duct 12 without passing through the desiccant.

[0046] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Fig.18As shown, the No. 1 ventilation plate 57 is rotatably connected to the No. 1 ventilation tube 56; a No. 2 connection structure 574 is provided on the No. 1 ventilation plate 57; a No. 1 gear ring 61 is fixedly connected to the No. 2 connection structure 574; a No. 2 motor 62 is provided above the No. 1 connection tube 13; the No. 2 motor 62 is fixedly connected to the No. 1 shell structure 131; the rotating shaft of the No. 2 motor 62 is connected to the No. 1 gear ring 61 via a No. 2 transmission mechanism 63; the No. 2 motor 62 is electrically connected to the controller.

[0047] When the axis of the No. 1 ventilation tube 56 coincides with the axis of the No. 1 connecting tube 13, the controller operates the No. 2 motor 62, which in turn drives the No. 1 gear ring 61 to rotate through the No. 2 transmission mechanism 63, which in turn drives the No. 2 connecting structure 574 to rotate, which in turn drives the No. 1 ventilation plate 57 to rotate, which in turn drives the No. 1 connecting structure 572 to rotate, which in turn drives the heat-conducting structure 573 to rotate, and thus stirs the desiccant, thereby improving the water absorption quality of the desiccant, and thereby improving the dehumidification effect of the ventilation device.

[0048] like Figure 4 , Figure 5 , Figure 8 and Fig. 9As shown, the conductive mechanism 59 includes a No. 3 mounting seat 591, a No. 3 magnet 592, a No. 4 sliding block 593, a No. 4 magnet 594, a No. 4 conductive column 595, a No. 4 conductive ring 596, a No. 3 connecting piece 597, a No. 3 conductive column 598 and a No. 3 conductive ring 599; the No. 3 mounting seat 591 is arranged on the No. 1 shell structure 131; the No. 3 mounting seat 591 is fixedly connected to the No. 1 shell structure 131; the No. 3 mounting seat 591 is provided inside There is a No. 3 mounting groove 5911; the No. 3 magnet 592 is fixedly connected to the bottom surface of the No. 3 mounting groove 5911; the No. 3 magnet 592 is an electromagnet; the polarity of the No. 3 magnet 592 is changeable; the No. 4 sliding block 593 is slidably connected in the No. 3 mounting groove 5911; one end of the No. 4 sliding block 593 is fixedly connected to the No. 4 magnet 594; the No. 4 magnet 594 is arranged close to the No. 3 magnet 592; the other end of the No. 4 sliding block is fixedly connected to the No. 4 magnet 594; The fourth conductive column 595 and the fourth conductive ring 596 are fixedly connected; the fourth conductive column 595 is connected to the positive pole of the heating power supply; the fourth conductive ring 596 is connected to the negative pole of the heating power supply; a fourth protrusion 5951 is provided on the end surface of the fourth conductive column 595; a fourth annular protrusion 5961 is provided on the end surface of the fourth conductive ring 596; a third connecting groove is provided on the first connecting structure 572; the third connecting piece 597 is fixedly connected in the third connecting groove; the third conductive column 598 and the third conductive ring 599 are fixedly connected on the third connecting piece 597; the third conductive column 598 is connected to the positive pole of the heating wire; the third conductive ring 599 is connected to the negative pole of the heating wire; a third groove 5981 is provided on the end surface of the third conductive column 598; a third annular groove 5991 is provided on the end surface of the third conductive ring 599; the third magnet 592 is electrically connected to the controller.

[0049] When the No. 1 ventilator 56 approaches the conductive mechanism 59 and stops moving, the staff energizes the No. 3 magnet 592 through the controller, thereby generating a magnetic force. At this time, the No. 3 magnet 592 and the No. 4 magnet 594 repel each other, thereby causing the No. 4 sliding block 593 to move out of the No. 3 mounting groove 5911, thereby causing the No. 4 sliding block 593 to move toward the side of the No. 3 connecting piece 597, thereby causing the No. 4 protrusion 5951 to abut against the No. 3 groove 5981, and at the same time causing the No. 4 annular protrusion 5961 to abut against the No. 3 annular groove 5991, thereby causing the positive pole of the heating wire to be connected to the positive pole of the heating power supply, and the negative pole of the heating wire to be connected to the negative pole of the heating power supply. Then the staff controls the The controller turns on the heating power supply, thereby energizing the heating wire, thereby baking the desiccant, thereby realizing the reuse of the desiccant; after the desiccant is baked, the controller stops the heating power supply and changes the polarity of the third magnet 592, thereby causing the third magnet 592 and the fourth magnet 594 to attract each other, thereby causing the fourth sliding block 593 to move into the third mounting groove 5911, thereby causing the fourth annular protrusion 5961 to disengage from the third annular groove 5991, and causing the fourth protrusion 5951 to disengage from the third groove 5981, thereby cutting off the power to the heating wire, and then the controller cuts off the power to the third magnet 592, thereby causing the fourth sliding block 593 to remain stationary under the action of the fourth magnet 594.

[0050] like Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, the connecting shaft structure 351 is rotatably connected to the No. 2 connecting plate 34; the No. 2 filter cartridge 35 is rotatably connected to the No. 2 connecting cartridge 32; the No. 3 motor 38 is fixedly connected to the No. 2 connecting plate 34; the rotating shaft of the No. 3 motor 38 is connected to the connecting shaft structure 351 via a No. 3 transmission mechanism 39; a No. 1 containing box 71 is provided below the No. 2 filter cartridge 35; the No. 1 containing box 71 is fixedly connected to the No. 2 connecting plate 34; a No. 1 shielding plate 72 is provided at the upper end of the No. 1 containing box 71; the upper surface of the No. 1 shielding plate 72 is fitted together with the side surface of the No. 2 filter cartridge 35; the No. 3 motor 38 is electrically connected to the controller.

[0051] Large particles of powder are easily adsorbed on the No. 2 filter hole 352, thereby reducing the suction force on the air inside the mine. While the No. 4 exhaust fan 33 is working, the No. 3 motor 38 rotates, and then drives the connecting shaft structure 351 to rotate through the No. 3 transmission mechanism 39, and then drives the No. 2 filter cartridge 35 to rotate, and then the large particles of powder adsorbed on the No. 2 filter hole 352 are scraped off through the No. 1 baffle plate 72, and then the large particles of powder adsorbed on the No. 2 filter hole 352 are cleaned up in time and stored in the No. 1 storage box 71, so as to ensure the suction force of the No. 4 exhaust fan 33 on the air in the mine, thereby increasing the speed of air movement, thereby improving the ventilation effect, and at the same time increasing the probability of the powder in the mine being brought to the No. 2 filter cartridge 35 by the air, thereby increasing the probability of the powder inside the mine being removed.

[0052] like Fig.10 , Fig.12 , Fig.13 , Fig.14 , Fig.16 and Fig.17 As shown, a No. 2 connecting groove is provided on the No. 2 filter plate 36; a No. 2 fixed cylinder 73 is provided in the No. 2 connecting groove; the No. 2 fixed cylinder 73 is fixedly connected to the No. 2 connecting cylinder 32; a scraping structure 731 is provided at one end of the No. 2 fixed cylinder 73; a scraping portion 7311 and a conveying groove 7312 are provided on the scraping structure 731; the conveying groove 7312 is communicated with the inner cavity of the No. 2 fixed cylinder 73; a No. 2 connecting pipe 74 is provided at the other end of the No. 2 fixed cylinder 73; the No. 2 connecting pipe 74 is fixedly connected to the No. 2 fixed cylinder 73; one end of the No. 2 connecting pipe 74 is communicated with the inner cavity of the No. 2 fixed cylinder 73; a vacuum cleaner 75 is provided at the other end of the No. 2 connecting pipe 74; the vacuum cleaner 75 is fixedly connected to the No. 2 connecting plate 34; the dust suction port of the vacuum cleaner 75 is communicated with the No. 2 connecting pipe 74; the vacuum cleaner 75 is electrically connected to the controller.

[0053] Small particles of powder are easily adsorbed on the No. 3 filter hole 361, reducing the suction force on the air inside the mine. When the No. 2 filter cartridge 35 rotates, it drives the No. 2 filter plate 36 to rotate, and the scraping structure 731 does not move, and then the small particles of powder adsorbed on the No. 3 filter hole 361 are promptly removed by the scraping part 7311, thereby ensuring the suction force of the No. 4 exhaust fan 33 on the air in the mine, thereby increasing the speed of air movement, thereby improving the ventilation effect, and at the same time increasing the probability of the powder in the mine being brought to the No. 2 filter cartridge 35 by the air, thereby increasing the probability of the powder inside the mine being removed; at the same time, the vacuum cleaner 75 works, thereby scraping the scraping part 7311 away. The small particles of powder generate suction, so that the small particles of powder scraped off by the scraping part 7311 enter the No. 2 fixed cylinder 73 through the conveying groove 7312, and enter the inside of the vacuum cleaner 75 through the No. 2 connecting pipe 74, thereby preventing the small particles of powder from accumulating at the bottom of the No. 2 filter plate 36, thereby preventing the small particles of powder from accumulating at the bottom of the No. 2 filter plate 36 to hinder the air flow, thereby ensuring the suction of the air in the mine by the No. 4 exhaust fan 33, thereby increasing the speed of air movement, thereby improving the ventilation effect, and at the same time increasing the probability of the powder in the mine being brought to the No. 2 filter cylinder 35 by the air, thereby increasing the probability of the powder inside the mine being removed.

[0054] like Figure 1 and Figure 3 As shown, the No. 1 connecting piece 24 is a split structure; the No. 2 ventilation duct 23 is fixedly connected to the No. 1 connecting piece 24; the No. 1 connecting piece 24 is rotatably connected to the No. 1 branch pipe 21; the No. 4 motor 25 is fixedly connected to the No. 1 branch pipe 21; the No. 4 motor 25 is connected to the No. 1 connecting piece 24 through a No. 4 transmission mechanism 26; the No. 4 motor 25 is electrically connected to the controller.

[0055] While the No. 3 exhaust fan 22 is working, the No. 4 motor 25 is working, and then the No. 1 connecting piece 24 is driven to rotate through the No. 4 transmission mechanism 26, and then the No. 2 ventilation tube 23 is driven to rotate, and then the plate structure 231 is driven to rotate, thereby increasing the probability of fresh air entering the mine and mixing with the original air inside the mine, thereby improving the ventilation quality.
