[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-5 The utility model provides a subway engineering support device, comprising: an arc-shaped top 1 and support plates 2 fixed to both ends of the outer wall of the bottom of the arc-shaped top 1, and also comprising: an air inlet pipe 3 installed on the inner wall of the bottom of the arc-shaped top 1, a fan 4 is installed on the inner wall of the air inlet pipe 3, and a branch air box 5 is connected to the top of the air inlet pipe 3, a first drying component 6 and a second drying component 7 are respectively installed on the outer walls of the two support plates 2 on opposite sides, and the inner wall of one side of the branch air box 5 is connected to the first drying component 6 through a first ventilation pipe 8, and the inner wall of the other side of the branch air box 5 is connected to the second drying component 6 through a second ventilation pipe 9. The drying component 7 is connected, and a motor 10 is installed on the inner wall of the arc-shaped top 1. A diversion component 11 is rotatably installed on the inner wall of the top of the air box 5, and a first rotating shaft 12 and a second rotating shaft 14 are rotatably installed on both ends of the outer wall of the bottom of the arc-shaped top 1. The first sealing plate 13 and the second sealing plate 15 are fixed at the bottom of the first rotating shaft 12 and the second rotating shaft 14 respectively, and a synchronization component 16 is installed on the diversion component 11. The diversion component 11 is connected to the first rotating shaft 12 and the second rotating shaft 14 through the synchronization component 16, and a controller 17 is installed on the inner wall of the bottom of the arc-shaped top 1.

[0020] It should be noted here that the supporting structure consisting of the arc-shaped top 1 and the two support plates 2 can be installed in the tunnel to support the tunnel, and desiccant can be put into the first drying component 6 and the second drying component 7. The air in the tunnel can be blown into the wind box 5 by the fan 4, and the air flow enters the first drying component 6 through the first ventilation pipe 8. After being dried by the desiccant in the first drying component 6, it is discharged to dehumidify the surrounding air. Since the supporting devices are installed in large numbers and relatively densely in the tunnel, they can achieve a better drying and dehumidifying effect on the air in the tunnel. When the desiccant adsorption in the first drying component 6 reaches a nearly saturated state, the motor 10 can be used to drive the diversion component 11 to rotate 180°, the airflow is introduced into the second ventilation pipe 9, and then the airflow is introduced into the second drying component 7, and is discharged after being dried by the desiccant in the second drying component 7. During the rotation of the diverter component 11, the first rotating shaft 12 and the second rotating shaft 14 can be driven by the synchronization component 16 to rotate 180° in the same direction, so that the first sealing plate 13 blocks the air outlet at the bottom of the first drying component 6, and at the same time the second sealing plate 15 opens the air outlet at the bottom of the second drying component 7 to facilitate air outlet. At this time, the desiccant in the first drying component 6 can be replaced, realizing the automatic alternating use of the first drying component 6 and the second drying component 7. When the desiccant is replaced, the dehumidification work of the air is not delayed.

[0021] In a preferred embodiment, the first drying component 6 includes a first box 601, a plurality of first mesh panels 602 equidistantly distributed and installed on the inner wall of the first box 601, a first humidity sensor 603 embedded on the outer wall of one side of the air outlet pipe at the bottom of the first box 601, and a first door panel 604 installed on the outer wall of one side of the first box 601.

[0022] It should be noted here that the desiccant can be laid on the first mesh plate 602, and the air flow enters from the top of the first box 601. After being adsorbed and dried by the desiccant, it can be discharged from the bottom of the first box 601. The humidity of the discharged air flow can be detected by the first humidity sensor 603. When the detected humidity is high, it means that the desiccant adsorption is about to reach saturation.

[0023] In a preferred embodiment, the second drying component 7 includes a second box 701, a plurality of second mesh panels 702 installed on the inner wall of the second box 701 and distributed at equal intervals, a second humidity sensor 703 embedded on the outer wall of one side of the air outlet pipe at the bottom of the second box 701, and a second door panel 704 installed on the outer wall of one side of the second box 701.

[0024] It should be noted here that the desiccant can be laid on the second mesh plate 702, and the air flow enters from the top of the second box 701. After being adsorbed and dried by the desiccant, it can be discharged from the bottom of the second box 701. The humidity of the discharged air flow can be detected by the second humidity sensor 703. When the detected humidity is high, it means that the desiccant adsorption is about to reach saturation.

[0025] In a preferred embodiment, the flow diversion component 11 includes a short shaft 1101 and an arc-shaped folded plate 1102 installed on the outer wall of the short shaft 1101.

[0026] It should be noted here that the motor 10 can drive the short shaft 1101 to rotate, thereby driving the arc-shaped folding plate 1102 to rotate, thereby adjusting the air outlet direction of the air inlet pipe 3.

[0027] In a preferred embodiment, the synchronization component 16 includes a driving wheel 1601 installed on the outer wall of the short shaft 1101, and a driven wheel 1602 installed on the first rotating shaft 12 and the second rotating shaft 14 respectively, and the two driven wheels 1602 are respectively connected to the driving wheel 1601 through a transmission belt 1603.

[0028] It should be noted that the rotation of the short shaft 1101 can drive the driving wheel 1601 to rotate, and then drive the two driven wheels 1602 to rotate through the two transmission belts 1603, and then drive the first rotating shaft 12 and the second rotating shaft 14 to rotate.

[0029] Working principle: The supporting structure consisting of the arc-shaped top 1 and the two support plates 2 can be installed in the tunnel to support the tunnel. Desiccant can be spread on the first mesh plate 602 and the second mesh plate 702. The air in the tunnel is blown into the wind box 5 through the fan 4. The airflow enters the first box 601 through the first ventilation pipe 8. After being adsorbed and dried by the desiccant, it can be discharged from the bottom of the first box 601. The humidity of the discharged airflow can be detected by the first humidity sensor 603. When the detected humidity is high, it means that the desiccant adsorption is about to reach saturation. At this time, the short shaft 1101 and the arc-shaped folding plate 1102 can be driven by the motor 10 to rotate 180°, and the airflow is introduced into the second ventilation pipe 9, and then the airflow is introduced into the second box 701. After being adsorbed and dried by the desiccant, it can be discharged from the bottom of the second box 701. The discharged air can be detected by the second humidity sensor 703. The humidity of the flow is detected. During the rotation, the short shaft 1101 can drive the driving wheel 1601 to rotate, and then drive the two driven wheels 1602 to rotate through the two transmission belts 1603, and then drive the first rotating shaft 12 and the second rotating shaft 14 to rotate 180 degrees in the same direction, so that the first sealing plate 13 blocks the air outlet at the bottom of the first box 601, and at the same time, the second sealing plate 15 opens the air outlet at the bottom of the second box 701 to facilitate air outlet. At this time, the desiccant in the first box 601 can be replaced. The air outlet at the bottom of the first box 601 is blocked by the first sealing plate 13, which can prevent the humid air from entering the first box 601 from the air outlet at the bottom of the first box 601 while waiting for the next replacement after the desiccant in the first box 601 is replaced, thereby realizing the automatic alternating use of the first box 601 and the second box 701. When the desiccant is replaced, the dehumidification work of the air is not delayed.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
