Abstract
The utility model discloses a multifunctional switch of a mining underground air door arlam, which comprises two housings arranged an underground air door body a door frame, wherein one housing is internally provided with a magnet, the other housing is internally provided with a reed pipe with a normally closed contact, the other reed pipe with a normally open contact, and a terminal. The utility model has the advantages that the multifunctional switch can carry out monitoring and alarming to the state of the underground air door. When in work, the utility model is used with a coal mine monitoring system, i.e. the reed pipe with the normally open contact is only connected with an underground air door monitoring system or an air door acousto-optic alarming device through the terminal. When the air door is closed, the acousto-optic alarming device does not alarm, and the monitoring system obtains an air door closed signal; when the air door is open, the acousto-optic alarming device reminds the passing personnel that the air door is open, and the same time, outputs an air door open signal to the monitoring system, so that the purpose that the underground air door working condition can be timely and accurately monitored can be realized.
Description
Technical field
The utility model relates to mining underground air door, especially relates to mining underground air door alarm multifunction switch.
Background technology
Air door is a kind of facility that mine is indispensable and application is more.It plays a part to be open to traffic in underworkings or pedestrian and don't make distinguished and admirable short circuit.The keying of underground air door is by manually-operated at present.Because negative pressure is big, the operating physical force that opens the door is very big, and is more the pedestrian, during particularly by vehicle, the unlatching of air door, closes very inconveniently, usually takes place that air door is not closed completely and the phenomenon that do not it is found that is brought hidden danger to downhole safety.
The utility model content
The utility model purpose is to provide a kind of mining underground air door alarm multifunction switch that air door opens and closes of monitoring.
For achieving the above object, the utility model can be taked following technical proposals:
Mining underground air door alarm multifunction switch described in the utility model, it comprises the two housings that is used to be installed on underground air door door body and the doorframe; Be provided with magnet in a housing therein, being provided with a contact in another housing is that normally closed type tongue tube, another contact are tongue tube open in usual and connection terminal.
The utility model advantage is to realize condition monitoring, the warning to underground air door.During work and mine supervision system support use, be that tongue tube open in usual is connected with underground air door supervisory system or air door acoustic-optic alarm by connection terminal and gets final product with described contact.Acoustic-optic alarm is not reported to the police when air door is closed, and supervisory system obtains the air door shutdown signal; Acoustic-optic alarm alarm holdee air door is not closed when door opening, export simultaneously air door not shutdown signal give supervisory system; Thereby reach the purpose of in real time accurate monitor well lower wind door duty.
Description of drawings
Fig. 1 is the structural representation of the utility model when being used for the underground air door closed condition.
Embodiment
As shown in the figure, mining underground air door alarm multifunction switch described in the utility model, it comprises housing 1 that is used to be installed on the underground air door door body and the housing 2 that is installed on the doorframe; At housing 1 internal fixation magnet 3 is arranged, at housing 2 internal fixation a contact being installed is that normally closed type tongue tube 4, another contact are tongue tube 5 open in usual and are used for described tongue tube 4,5 terminals and the supervisory system of underground air door, the connection terminal 6 that warning device is electrically connected.
