[0002] The tunnel buried underground can provide space for pipelines and cables, and the tunnel is ventilated through a ventilation house installed on the ground. The current tunnel ventilation house intercepts foreign objects by setting louvers at the side openings, but in rainy weather, the louvers are still in an open state, and the staff cannot close the louvers at the tunnel ventilation openings. The water vapor in the air and the splashing water will enter the tunnel through the gaps in the louvers, causing the humidity in the tunnel to increase, which will cause damage to the pipes and cables in the tunnel.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Please refer to Figures 1 - 4 , the present utility model provides the following technical solutions: A ventilation device for a pipe gallery, including an above-ground ventilation house 1 of the pipe gallery. A limit support frame 2 is hinged to the side wall of the above-ground ventilation house 1. An air intake drying assembly 3 is provided on the inner wall of the limit support frame 2. The air intake drying assembly 3 includes a support mesh plate 31, a plurality of desiccant storage bags 32, a plurality of desiccant storage strips 33, and a support connection piece 34. The support mesh plate 31 is arranged inside the limit support frame 2. A plurality of desiccant storage bags 32 are fixedly connected to the inner wall of the support mesh plate 31. A plurality of desiccant storage strips 33 are respectively fixedly connected to the bottom ends of the plurality of desiccant storage bags 32. The support connection piece 34 is fixedly connected to the top end of the support mesh plate 31.

[0017] In this implementation: The above-ground ventilation house 1 of the pipe gallery is connected to the underground pipe gallery, and the pipe gallery is ventilated by means of the above-ground ventilation house 1 of the pipe gallery. During normal use, desiccants that can be reused after drying are provided in the desiccant storage bags 32 and desiccant storage strips 33. Magnets are provided on one side of the support mesh plate 31, and the support mesh plate 31 is adsorbed and fixed on the inner wall of the ventilation opening intercepting fan blade 21 through the magnets. The desiccant storage bags 32 and desiccant storage strips 33 are supported by means of the support mesh plate 31 and the support connecting piece 34, so that the desiccant storage bags 32 and desiccant storage strips 33 can be stably distributed inside the ventilation opening intercepting fan blade 21. Moisture contacts the desiccant storage bags 32 and desiccant storage strips 33, and the air entering the above-ground ventilation house 1 of the pipe gallery is dried by the desiccants in the densely distributed desiccant storage bags 32 and desiccant storage strips 33, preventing a large amount of water vapor from entering the above-ground ventilation house 1 of the pipe gallery during rainy weather. And on sunny days, after the staff flips the limit support frame 2 and the ventilation opening intercepting fan blade 21, and then flips the support mesh plate 31 again, it can drive the intake drying assembly 3 as a whole to flip, so that the desiccant storage bags 32 and desiccant storage strips 33 cover the outside of the limit support frame 2 and the ventilation opening intercepting fan blade 21, and the soaked desiccants are dried by sunlight and external air flow to facilitate the reuse of the desiccants. During the drying process of the desiccants, the staff covers the limit support frame 2 and the ventilation opening intercepting fan blade 21 at the lateral opening of the above-ground ventilation house 1 of the pipe gallery to prevent foreign objects from entering the above-ground ventilation house 1 of the pipe gallery during the drying process of the desiccants. After the desiccants are dried, the staff flips the limit support frame 2 and the ventilation opening intercepting fan blade 21 to open again and then resets the intake drying assembly 3 as a whole.

[0018] The ventilation opening intercepting fan blade 21 is fixedly connected to the inner wall of the limit support frame 2, and the support mesh plate 31 is magnetically connected to the ventilation opening intercepting fan blade 21; by providing the ventilation opening intercepting fan blade 21, it can cooperate with the limit support frame 2 to intercept the lateral opening of the above-ground ventilation house 1 of the pipe gallery, preventing foreign objects from entering the above-ground ventilation house 1 of the pipe gallery while allowing air flow to enter the above-ground ventilation house 1 of the pipe gallery through the ventilation opening intercepting fan blade 21.

[0019] A relief groove 22 is provided at the top of the ventilation opening intercepting fan blade 21, and a connecting shaft rod 341 is fixedly connected to the top of the support connecting piece 34. The connecting shaft rod 341 is rotatably connected to the inner wall of the relief groove 22; by providing the relief groove 22, it can make way for the support connecting piece 34 and the connecting shaft rod 341, so that the support connecting piece 34 can be connected to the support mesh plate 31 through the gap at the top of the ventilation opening intercepting fan blade 21 via the relief groove 22. When the support mesh plate 31 is flipped, the support connecting piece 34 and the connecting shaft rod 341 also flip.

[0020] A plurality of desiccant packaging bags 32 and a plurality of desiccant packaging strips 33 are sleeved with a protective support mesh frame 35 on the outside. The protective support mesh frame 35 is fixedly connected to the inner wall of the support mesh plate 31. By providing the protective support mesh frame 35, the desiccant packaging bags 32 and the desiccant packaging strips 33 can be protected to prevent the desiccant packaging bags 32 and the desiccant packaging strips 33 from being directly exposed when they are flipped to the outside of the limit support border 2 and the ventilation opening intercepting fan blades 21, so as to avoid damage to the desiccant packaging bags 32 and the desiccant packaging strips 33 caused by personnel and objects.

[0021] The border size of the limit support border 2 is larger than the side opening size of the above-ground ventilation house 1 of the pipe gallery. The width of the desiccant packaging bag 32 located below is larger than the width of the desiccant packaging bag 32 located above. The larger border size of the limit support border 2 enables the limit support border 2 to fit on the outside of the above-ground ventilation house 1 of the pipe gallery to play a limiting role. The size of the desiccant packaging bag 32 matches the shape and size of the limit support border 2 and the ventilation opening intercepting fan blades 21.

[0022] The working principle and usage process of the present utility model: With the help of the above-ground ventilation house 1 of the pipe gallery, ventilation of the pipe gallery can be carried out. During normal use, a magnet is provided on one side of the support mesh plate 31, and the support mesh plate 31 is adsorbed and fixed to the inner wall of the ventilation opening intercepting fan blades 21 through the magnet. The support mesh plate 31 and the support connecting piece 34 support the desiccant packaging bags 32 and the desiccant packaging strips 33. The desiccant packaging bags 32 and the desiccant packaging strips 33 are distributed inside the ventilation opening intercepting fan blades 21. The desiccant in the densely distributed desiccant packaging bags 32 and desiccant packaging strips 33 dries the air entering the above-ground ventilation house 1 of the pipe gallery. And on a sunny day, after the staff flips the limit support border 2 and the ventilation opening intercepting fan blades 21, the support mesh plate 31 is flipped again to cover the desiccant packaging bags 32 and the desiccant packaging strips 33 on the outside of the limit support border 2 and the ventilation opening intercepting fan blades 21, and the wet desiccant is dried by sunlight and external air flow. During the process of drying the desiccant, the staff covers the limit support border 2 and the ventilation opening intercepting fan blades 21 at the lateral opening of the above-ground ventilation house 1 of the pipe gallery. After the desiccant is dried, the staff flips the limit support border 2 and the ventilation opening intercepting fan blades 21 open again and then resets the intake air drying assembly 3 as a whole.
