The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As Fig. 1, a kind of confined space operation of the utility model protective device for respiration, it comprises air feed full facepiece mask 1, power switch 3, air pump 2 and pneumatic filter 4, the inlet end of air pump is connected with air feed full facepiece mask 1 with pneumatic filter 4 by tracheae 5 respectively with the outlet side, power switch 3 is electrically connected with air pump 2, is used for external power supply and powers.External power supply switch and pneumatic filter can provide air feed and power supply uninterruptedly to the operating personnel who wears the air feed full facepiece mask.
The air inlet place of air feed full facepiece mask 1 is provided with flow valve 6, and the throughput according to operating personnel's needs are regulated the air feed full facepiece mask makes that operating personnel's comfort level is guaranteed.In addition, in order to fix flow valve 6 when the operation, present embodiment also is provided with waistband, and the pipeline that this waistband and air feed full facepiece mask are connected with flow valve connects, and is worn on when operation on operating personnel's the waist to fix flow valve.
Present embodiment also comprises stand-by power supply 7, and stand-by power supply 7 is electrically connected with air pump and power switch 3, when external power supply cuts off the power supply, can carry out supply by stand-by power supply.
As shown in Figure 2, use in order to be adapted to different confined space places, present embodiment also comprises go-cart 8, and wherein, power switch 3, air pump 2 and pneumatic filter 4 are installed in this go-cart 8, and go-cart is set can conveniently carry.In addition, stand-by power supply 7 also is located in this go-cart 8.
In order to realize the automatic control of entire job protective device for respiration, also be provided with control panel 9 in the go-cart, control panel is electrically connected with air pump and power switch, controls power supply and air feed by the button on the control panel 9.Also be provided with air feed full facepiece mask storage box 10 in the go-cart 8, be used for the flow valve of depositing the air feed full facepiece mask and being connected with the air feed full facepiece mask.
