Abstract
A wireless video camera for mines according to the utility model comprises a housing. The housing is internally provided with a power supply unit, a camera unit, a video converting unit and a wireless transmitting unit; wherein the power supply unit, the camera unit, the video converting unit and the wireless transmitting unit are connected. The housing is further internally provided with a wireless voice communication module, a loudspeaker, a microphone and a conversation button; wherein the loudspeaker, the microphone and the conversation button are connected with the wireless voice communication module. The edge of the loudspeaker abuts against the inner wall of the housing and is connected with the same through a bolt. The edge of the loudspeaker is provided with an annular slot. A sealing gasket which closely abuts against the inner wall of the housing is embedded into the slot. A filtering net covers the loudspeaker. The housing is provided with through holes which correspond with the loudspeaker and the microphone. The wireless video camera for the mines is advantageous in that: compact structure and reasonable design are realized; voice conversation can be performed in video acquisition; furthermore the image is transmitted through a wireless network; not only can image be seen, but also intercommunication can be realized; and the wireless video camera is particularly convenient on conditions of debugging the video camera or winch ticking, etc.
Description
Technical field
The utility model relates to a kind of mine wireless camera instrument.
Background technology
At present, traditional video camera is wired, and the transmission medium of use is coaxial cable or optical fiber, be unfavorable for the use of mobile monitoring face, and present wireless camera instrument generally do not possess the function of voice call, while use under mine, safety and anti-dust performance are not high, and function is comparatively single.
Summary of the invention
For solving above technical deficiency, the utility model provides a kind of mine that possesses speech communication function wireless camera instrument.
The utility model is realized by following measures:
A kind of mine wireless camera instrument of the present utility model, comprises shell, in described shell, is provided with and is connected
Power subsystem, camera unit, video converting unit and wireless transmitting unit, the loudspeaker, microphone and the push-to-talk button that in described shell, are provided with wireless speech communication module and are connected with wireless speech communication module, described loudspeaker edge pastes merga pass bolt with outer casing inner wall and is connected, loudspeaker edge is provided with annular draw-in groove, described draw-in groove is embedded in the seal washer of being close to outer casing inner wall, on described loudspeaker, be coated with filter screen, on described shell, be provided with the through hole relative with loudspeaker and microphone.
Above-mentioned wireless transmitting unit is connected with positioning antenna, and described positioning antenna is connected with L shaped runing rest, and described runing rest comprises the montant and the cross bar that connect by rotating shaft, and described cross bar is connected to outer casing end.
In above-mentioned shell, be provided with L shaped bracket, bracket one end is bolted on shell end face, described camera unit is arranged on bracket, on described bracket, be also provided with installing rack, described installing rack is provided with the dividing plate of upper and lower some layers, described video converting unit, wireless transmitting unit and wireless speech communication module are integrated in respectively independently on circuit board, and each circuit board is separately positioned on each dividing plate of installing rack.
The beneficial effects of the utility model are: compact conformation, reasonable in design, can in video acquisition, carry out voice call, and pass through wireless network transmissions, not only can see image, can also carry out intercommunication, especially use more convenient at debugging video camera or getting ready to winch etc. in the situation that.
Brief description of the drawings
Fig. 1 is the structural representation of invention.
Fig. 2 is that the A-A of Fig. 1 is to cross-sectional view.
Fig. 3 is the cross-sectional view of loudspeaker.
Fig. 4 is the structure for amplifying schematic diagram of C in Fig. 3.
Wherein: 1 shell, 2 camera unit, 3 loudspeaker, 4 brackets, 5 installing racks, 6 dividing plates, 7 positioning antennas, 8 through holes, 9 push-to-talk buttons, 3-1 filter screen, 3-2 seal washer.
Embodiment
As shown in Figure 1, 2, a kind of mine wireless camera instrument of the present utility model, comprises shell 1, shell 1
Inside be provided with the power subsystem, camera unit 2, video converting unit and the wireless transmitting unit that are connected,
Power subsystem provides power supply for whole device.After camera unit 2 capture video signals, change through video converting unit, and send out by wireless transmitting unit.The loudspeaker 3, microphone and the push-to-talk button 9 that in shell 1, are provided with wireless speech communication module and are connected with wireless speech communication module, be provided with the through hole 8 relative with microphone with loudspeaker 3 on shell 1.Open after push-to-talk button 9, by the information transmission of wireless speech communication module, personnel can carry out intercommunication, also can hear broadcast announcement.
As shown in Figure 3,4, loudspeaker 3 edges paste merga pass bolt with shell 1 inwall and are connected, and loudspeaker 3 edges are provided with annular draw-in groove, and draw-in groove is embedded in the seal washer 3-2 that is close to shell 1 inwall, is coated with filter screen 3-1 on loudspeaker 3.Filter screen 3-1 and seal washer 3-2 can prevent that the dust in mine from entering video camera.Wireless transmitting unit is connected with positioning antenna 7, and positioning antenna 7 is connected with L shaped runing rest, and runing rest comprises the montant and the cross bar that connect by rotating shaft, and cross bar is connected to shell 1 end.Adopt positioning antenna 7 to transfer signals to farther, image is more clear.
What shell 1 adopted is 304 stainless steels, and intensity is high and attractive in appearance.In shell 1, be provided with L shaped bracket 4, bracket 4 one end are bolted on shell 1 end face, camera unit 2 is arranged on bracket 4, on bracket 4, be also provided with installing rack 5, installing rack 5 is provided with the dividing plate 6 of upper and lower some layers, and video converting unit, wireless transmitting unit and wireless speech communication module are integrated in respectively independently on circuit board, circuit board is the requirement according to GB3836-2010DE, be the circuit design of essential safe type, safety possibility, reduces the dangerous possibility occurring.Each circuit board is separately positioned on each dividing plate 6 of installing rack 5, improves thermal diffusivity, and avoids the contact short circuit between circuit, improves fail safe.As long as in the place that has video camera, not only can see its image, can also carry out intercommunication, especially use more convenient at debugging video camera or getting ready to winch etc. in the situation that.
The above is only the preferred implementation of this patent; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the art of this patent principle; can also make some improvement and replacement, these improvement and replacement also should be considered as the protection range of this patent.
