Description

A kind of underground broadcast phone

Technical field

The utility model relates to underground broadcasting equipment fields, broadcast phone more particularly to a kind of underground.

Background technique

Underground work working environment is complicated, and risk is big, and encountering situation can not link up with the external world in time, Frequent Accidents.It is existing Generally communicated by intercom in mine, but due to subsurface environment complexity, difficult wiring, signal difference, communication function by To limitation.Dust is more in mine, and phone is easy to be blocked, and influences phone service life.Major part mine is fitted at present Personnel localization base station, that is to say, that there is the place of personnel localization base station just to have local area network, how to utilize underground location base station office Domain network is carried out down-hole information transmitting, is had a very important significance.

Utility model content

The purpose of this utility model is to provide for a kind of underground broadcast phone, makes its good dustproof effect, long service life can Local net layout is made full use of, underground unwrapping wire is reduced, reduces cost.

To solve the above problems, the utility model provides a kind of underground broadcast phone, including fuselage, dust-proof upper cover, microphone, Key and loudspeaker, the fuselage interior is equipped with loudspeaker mounting groove and chip installs room, installation in the loudspeaker mounting groove There are loudspeaker, dust seal is equipped between loudspeaker and loudspeaker installation room, chip installation indoor location has chip, and chip and chip are pacified It fills and is equipped with elastomeric pad between room, the side of fuselage is equipped with loudspeaker, and loudspeaker inside or exit are equipped with Air Filter, core By connection between piece and loudspeaker, chip and loudspeaker, body upper is equipped with panel cover, panel cover be equipped with key and Microphone places mouth, is also equipped with dust-proof upper cover on the fuselage, sealing ring, dust-proof upper cover and fuselage are equipped on dust-proof upper lid Junction is equipped with closing lid spring.

Further, dustproof membrane is posted on the key.

By adopting such a design, the utility model at least has the following advantages:

Using personnel localization base station already installed under mine, personnel localization base station is accessed by RJ45 cable, makes institute Have and a local area network is linked to be to speaking machine by be mounted, both can be with both-way communication, can also be with point-to-point intercommunication, it can be with one Key call scheduling room, as long as having the tunnel of base station that the function may be implemented, without being especially routed.Both the pressure of unwrapping wire had been reduced Cost is also reduced, has also achieved the safety requirements of Work Safety Supervision Bureau, it may be said that fund and space of mine is greatly saved.

Phone is broadcasted in underground has dust-proof upper cover, can prevent dust in mine from blocking phone, and increase at loudspeaker Dust seal, good dustproof effect extend the service life of phone, chip and are equipped with elastic cushion between chip installation room Piece, it is possible to reduce damage of the vibration to chip increases sound amplification function, prevent the too small operating personnel of volume from cannot hear in time extensively It broadcasts.

Detailed description of the invention

Above-mentioned is only the general introduction of technical solutions of the utility model, in order to better understand the technology hand of the utility model Section, below in conjunction with attached drawing, the utility model is described in further detail with specific embodiment.

Fig. 1 is a kind of structural schematic diagram of underground broadcast phone of the utility model.

Fig. 2 is the internal structure chart of the underground broadcast phone of the utility model.

Fig. 3 is the structural schematic diagram of loudspeaker opening installation Air Filter.

Fig. 4 is the network connection schematic diagram for broadcasting phone.

Wherein, 1 is fuselage, and 2 be dust-proof upper cover, and 3 be chip, and 4 be loudspeaker mounting groove, and 5 be dust seal, and 6 be loudspeaker, 7 be elastomeric pad, and 8 be loudspeaker, and 9 be Air Filter, and 10 be sealing ring, and 11 place mouth for microphone, and 12 be microphone, and 13 be closing lid bullet Spring.

Specific embodiment

Referring to Fig.1 shown in -3, the utility model provides a kind of underground broadcast phone, including fuselage 1, dust-proof upper cover 2, words Cylinder 12, key and loudspeaker 8 are equipped with loudspeaker mounting groove 4 inside the fuselage 1 and chip install room, the loudspeaker installation Loudspeaker 6 are installed in slot 4, dust seal 5 is equipped between loudspeaker 6 and loudspeaker installation room 4, chip installation indoor location has chip 3, it is equipped with elastomeric pad 7 between chip 3 and chip installation room, the side of fuselage 1 is equipped with loudspeaker 8,8 inside of loudspeaker or goes out Air Filter 9 is installed at mouthful, by connection between chip and loudspeaker, chip and loudspeaker, body upper is equipped with panel Lid, panel cover are equipped with key and microphone and place mouth 11, are also equipped with dust-proof upper cover 2 on the fuselage 1, in dust-proof upper cover 2 Sealing ring 10 is installed, dust-proof upper cover 2 is equipped with closing lid spring 13 with fuselage junction.

Dustproof membrane is posted on the key.

The dust-proof upper cover is made of explosion-proof lamp, and usually phone when not used, is buckled upper cover, adopted between upper cover and fuselage It is sealed with sealing strip, prevents dust from entering in phone.Broadcast volume is smaller when to prevent phone upper cover from covering, and personnel in the pit listens not See, increase a loudspeaker in fuselage side, can expand volume, loudspeaker opening be it is horn-like, in flare openings or Air Filter is installed at flare openings, can prevent dust from entering in loudspeaker, increases the service life of loudspeaker.

Referring to shown in Fig. 4, due to being equipped with personnel localization base station in mine, base station network can be adequately utilized, makes to own Broadcast phone be added in local area network, do not have to individual unwrapping wire.The underground broadcast phone passes through route and personnel positioning Base station connection, personnel localization base station are connect by optical cable or cable with system controller, and system controller is connect with terminating machine.Behaviour Various broadcasting instructions or information can be issued by terminating machine by making personnel, and staffs working in the mine receives information by broadcasting phone, To react in time, there is something special, and terminating machine is fed back on well in time.

The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model Limitation, those skilled in the art make a little simple modification, equivalent variations or modification using the technology contents of the disclosure above, It falls within the protection scope of the present utility model.
