Description
Technical field
The utility model relates to a kind of underground space air feeder.
Background technology
Field work, during especially open-air tunnel operation, rarefaction of air in the tunnel, very easily cause workmen's expiratory dyspnea in the tunnel, anoxic, dizzy, the serious harm workmen is healthy, the reduction operating efficiency, even life danger might appear, and at present general air transport device is bulky, power consumption is high, assembling is difficult, and open-air use is very inconvenient.
The utility model content
The purpose of this utility model provides a kind of underground space air feeder, and the workmen is for the demand of fresh air in the time of can solving open-air tunnel operation on the one hand, and it is convenient, easy to use to carry on the other hand, is convenient to use when the field does not have the electricity consumption condition.
The purpose of this utility model is achieved through the following technical solutions:
A kind of underground space air feeder comprises support and air transport device, and air transport device is fixed on the support; Described air transport device comprises cylindrical shell, push rod, inlet one-way valve and outlet check valve, and push rod is located at the top of cylindrical shell and closely is slidingly matched with cylinder inboard wall, and the push rod top is provided with pressing plate, is provided with some springs between pressing plate and the support; Described inlet one-way valve and outlet check valve are symmetrically set in respectively the two ends of the bottom of cylindrical shell, and inlet one-way valve external port place is connected to air induction hose, and outlet check valve external port is connected to air-out hose.
The beneficial effects of the utility model are: the workmen and carries conveniently, easy to use for the demand of fresh air when fully satisfying open-air tunnel operation, is convenient to use when the field does not have the electricity consumption condition.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is the structural representation of the described a kind of underground space air feeder of the utility model embodiment;
Among the figure:
1, support; 2, cylindrical shell; 3, push rod; 4, pressing plate; 41, spring; 5, air transport device; 6, inlet one-way valve; 7, outlet check valve; 8, air induction hose; 9, air-out hose.
The specific embodiment
As shown in Figure 1, a kind of underground space air feeder shown in the utility model embodiment comprises support 1 and air transport device 5, and air transport device 5 is fixed on the support 1; Described air transport device 5 comprises cylindrical shell 2, push rod 3, inlet one-way valve 6 and outlet check valve 7, and push rod 3 is located at the top of cylindrical shell 2 and closely is slidingly matched with cylindrical shell 2 inwalls, and push rod 3 tops are provided with pressing plate 4, are provided with some springs 41 between pressing plate 4 and the support 1; Described inlet one-way valve 6 and outlet check valve 7 are symmetrically set in respectively the two ends of the bottom of cylindrical shell 2, and inlet one-way valve 6 external port places are connected to air induction hose 8, and outlet check valve 7 external port are connected to air-out hose 9.
During concrete the use, support 1 and air transport device 5 place outside air, air-out hose 9 are probeed in the underground space of operation, and air induction hose 8 is placed outside air, extraneous fresh air enters cylindrical shell 2 by inlet one-way valve 6 when lifting pressing plate 4, exports check valve 7 closures this moment; When depressing pressing plate 4, inlet one-way valve 6 closures, the fresh air in the cylindrical shell 2 is discharged cylindrical shell by outlet check valve 7, decontrols pressing plate 4, and then pressing plate 4 returns to by spring 41 and lifts the position, sucks simultaneously extraneous fresh air, and so forth.Also support 1 and air transport device 5 can be placed in the underground space during use, and air induction hose 8 is placed in the underground space, air-out hose 9 is placed outside air, can discharge the turbid air in the underground space, and descend easily the workmen to use.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, all drops within the protection domain of the present utility model.
