example

[0026] Example: such as Figure 1 to Figure 5 , what this example specifically relates to is a kind of ventilating device for the gas cabin of the underground comprehensive pipe gallery, which is composed of a ventilating shaft 1, a lifter 4 installed in the ventilating shaft 1, a grille 3 with a vent on the top, and a warning sign attached to the outer wall 5 folding air duct 2, ventilation unit 8 and controller 9 installed below the ventilation shaft 1, combustible gas detector 6 and environmental parameter detector 7 installed in the gas cabin are formed together. A ring flange is arranged on the inner wall of the ventilation shaft 1, and the bottoms of the foldable air duct 2 and the lifter 4 are fixedly installed on the flange of the inner wall of the ventilation shaft 1, and the upper end of the lifter 4 is connected with the upper end of the foldable air duct 2.

[0027] The outer diameter of the air vent grille 3 is slightly larger than the inner diameter of the air sh...

Abstract

The invention relates to a lifting-type vent for an underground building. The lifting-type vent for the underground building is characterized in that a foldable air duct and a lifting device are arranged on the inner side of a vent shaft; the foldable air duct and the lifting device are both fixedly arranged on the inner wall of the vent shaft; the upper end of the lifting device is connected with the upper end of the foldable air duct; a vent grating is arranged on the top of the foldable air duct; at a normal vent working condition, the lifting device and the foldable air duct are at a contraction state; the vent grating on the top of the foldable air duct is flush with the shaft opening of the vent shaft; and at an accident vent working condition, the lifting device is triggered to lift upwards, and the foldable air duct extends upwards along with rising of the lifting device, so that the vent grating at the top of the foldable air duct is higher than the shaft opening of the vent shaft by a certain safe distance. According to the lifting-type vent for an underground building, the height of the vent of the vent shaft is automatically adjusted according to the normal vent or accident vent working condition; during normal vent, the vent grating can be flush with the ground or is convex slightly so that a surrounding landscape is not affected; during accident vent, the vent is lifted, so that safe height and warning requirement is met; and the lifting-type vent for the underground building is simple in structure and low in cost.

Description

technical field [0001] The invention relates to a ventilation device for an underground structure, in particular to a lifting vent for an underground structure and a ventilation device for a gas cabin of an underground comprehensive pipe gallery using the vent. Background technique [0002] Ventilation devices are an important part of underground structures such as underground spaces, tunnels, and integrated pipe corridors. The ventilation, moisture removal, heat removal, or removal of internal toxic and harmful gases of underground structures need to be achieved through convection between the ventilation device and the ground air. With the continuous expansion of the scale of underground structures, the number of vents protruding from the ground in the ventilation device also increases, and most of the vents are built near the road. [0003] When underground structures are normally ventilated for moisture removal, heat removal, and ventilation, the ground vents of the venti...
