Detailed Description

The drawings in the embodiments of the present invention will be combined; the technical scheme in the embodiment of the utility model is clearly and completely described; obviously; the described embodiments are only some of the embodiments of the present invention; rather than all embodiments. Based on the embodiment of the utility model; all other embodiments obtained by a person skilled in the art without making any inventive step; all belong to the protection scope of the utility model.

referring to fig. 1-5, a ventilation device for underground construction by reverse construction method comprises a fan 1, wherein the fan 1 is communicated with one end of a ventilation main pipe 2, the other end of the ventilation main pipe 2 penetrates through soil and is communicated with the top end of a middle pipe 3, the side surface of the middle pipe 3 is fixedly connected and communicated with the left side surface of an inner air pipe 4, the right side surface of the inner air pipe 4 is fixedly connected with the left side of an elastic soft cloth 5, the right side surface of the inner air pipe 4 is sleeved in a transition pipe 6, the right side of the elastic soft cloth 5 is fixedly connected with the left side of the transition pipe 6, and an air outlet 7 is arranged at the bottom end of the transition pipe 6.

The two sides of the middle pipe 3 are fixedly connected with first fixing lugs 8, and the two sides of one end of the inner air pipe 4 and one end of the transition pipe 6 close to the middle pipe 3 are rotatably connected with one end of a second fixing lug 9.

The transition pipes 6 are provided with a plurality of transition pipes, and the adjacent transition pipes 6 are sleeved.

Two sides of the transition pipe 6 are provided with connecting holes 10, and the connecting holes 10 are connected with sealing covers.

The lower surface of the second fixing lug 9 is provided with a comb-shaped groove 11, a sliding block 12 is connected in the groove 11 in a sliding manner, and one end of a fine wire 13 is fixedly connected to the bottom end of the sliding block 12;

The bottom is hollow structure under the transition pipe 6, and hollow structure is inside to be provided with the elasticity cloth layer, elasticity cloth layer around and hollow structure inward flange fixed connection, the middle part seted up with the air outlet elastic hole 14 that matches, the other end of fine rule 13 is connected at the left and right both ends in elastic hole 14.

The inside air-out pipe that is provided with of transition pipe 6, the one end that goes out the air pipe is connected with subaerial air exhauster after passing ventilation house steward 2, and the connecting hole 10 is connected to the other end, goes out the air pipe and is the scalable form of fold.

the working principle is as follows:

The utility model discloses when practical, at first dig a passageway in underground construction layer and bottom surface support can, also can arrange the ventilation house steward along the exit on underground construction layer and go, then the top surface on underground construction layer sets up the intermediate pipe, the intermediate pipe is inside to be provided with the arc surface, turn into the wind of vertical decurrent wind into horizontally wind, the first fixed ear of intermediate pipe top simultaneously passes through the long screw to be fixed in the top surface on underground construction layer, later intermediate layer fixed connection interior tuber pipe, interior tuber pipe passes through elasticity soft cloth and transition union coupling, the main effect of elasticity soft cloth is that both can realize interior tuber pipe and transition union coupling, also can realize when the transition pipe separates from interior tuber pipe or transition pipe and transition pipe, still can realize sealedly, the transition pipe is made for light material, when a plurality of transition pipes cup joint, worry not because weight and too big problem of gravity; by the utility model, the pipeline can be stretched and constructed, namely stretched;

Under the condition that the power of the fan is fixed, the input wind is also fixed, when the construction length is longer, constructors concentrate on the position far away from the outlet, namely the position far away from the middle pipe, at the moment, if the wind power of the transition pipe close to the middle pipe is not reduced, little fresh wind is left for conveying to the tail end, so after the transition pipe is extended, the second fixing lug of the inner section can automatically bounce, the automatic bouncing technology is not the prior art, or the second fixing lug is made of rubber materials, the compressed state is always treated because of the transition pipe, in a word, when the transition pipe is not arranged outside the second fixing lug, the second fixing lug can automatically bounce to drive a thin wire and further drive an elastic hole to elongate, the elastic hole becomes flat when elongate, the area of the elastic hole becomes small, the introduced wind at the moment can be reduced, if the elastic hole at the position is closed, the sliding block is moved to the farthest position far away from the transition pipe, at the moment, the larger the pulling force received by the elastic hole is, the area is infinitely close to zero, meanwhile, after the second fixing lug bounces, the second fixing lug needs to be fastened with the top surface of the underground construction layer through a long screw, and after the second fixing lug is fastened, the sliding of the sliding block is not influenced by the nut of the long screw; by the utility model, the wind power at each transition pipe can be changed, and the wind can be intensively conveyed to the tail end;

When needs carry out the exhaust, go deep into the transition intraductal with the hand through the air outlet, then extend to going out the tuber pipe, then carry out threaded connection with the connecting hole, then connect the tuber pipe of going out with the connecting hole in the outside, then open the air exhauster, go out the convulsions, go out the tuber pipe and run through behind the ventilation house steward and be connected with the air exhauster, go out tuber pipe surface and ventilation house steward's wall sealing connection, when not needing the exhaust, seal up the connecting hole with sealed lid.

The above; is only a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto; any person skilled in the art is within the technical scope of the present disclosure; according to the technical scheme of the utility model and the improvement conception, equivalent substitution or change is carried out; are all covered by the protection scope of the utility model.
