Description
Technical field
The present invention relates to fibre optic transmitter, especially relates to a kind of ore deposit hole rock-fall proof video monitoring light-emitting device.
Background technology
The effect of optical sender is that the signal of telecommunication sent from electric terminal is transformed into optical signal, and sends into fibre circuit and carry out
Transmission.
In existing mine, monitoring system generally by fiber-optic transfer video signal, rare lose than more visible by image
Lose, photographic head detection to data is activation to an optical sender, optical transmitter by the signal of telecommunication of photographic head be converted into light letter
Number transmission get on, but it is all explosion-proof to be currently used for the optical sender in mine because dust is more in mine, optical sender
If blow-by, it is easy to cause blast, and the sealing member that outlet is arranged on the wall of side is horizontal-extending, is fallen when there is stone
When falling, sealing member may be pounded disconnected.
The content of the invention
The purpose of the present invention is to overcome the shortcomings of present technology, there is provided a kind of ore deposit hole rock-fall proof video monitoring light transmitting
Equipment, solves the optical sender in existing mine, and sealing member easily pounds disconnected defect by stone.
The present invention is achieved through the following technical solutions：Ore deposit hole rock-fall proof video monitoring light-emitting device, including shell
Body, housing upper end open, and be provided with cover plate sealing, cover plate contacts with the side of prolonging in " mouth " shape of housing, cover plate with prolong side it
Between be provided with sealing ring, be provided with multiple threading holes in housing sidewall, described threading hole outside is provided with sealing member, sealing member
In inverted L shapes, the perforation of bearing of trend is provided with sealing member, sealing member one end is horizontal, and the other end straight down, is worn
Hole connects threading hole, and sealing member port directed downwardly is poroid in ladder, i.e., including macropore and aperture, described macropore is near sealing
Part towards lower port, macropore female thread is connected with a tamponade, and O-ring is provided between tamponade and aperture, and tamponade is extended along
Direction is provided with via, and described cover plate is rounded, and cover plate covers all of sealing member.Cover plate and prolonging pass through between side
Sealing ring is sealed, it is ensured that dust will not be entered in housing, and encapsulation process, specifically L-shaped are carried out by sealing member at threading hole
Sealing member, one end connection threading hole, the other end straight down, arranges tamponade and O-ring sealed, usually O at the end
The aperture of type circle, the aperture of via in tamponade, the aperture of aperture all with enter lines matching, O-ring is oppressed in tamponade, by O-ring court
Oppress point of incoming cables so that sealing member can be sealed to threading hole.Down, dust is difficult to for the port of the sealing member of this device
Port accumulates, so that O-ring is not easy to contaminate dirt, need not spend carry out dust removal step extra time when being keeped in repair,
Save the time, and sealing member is L-shaped, when optical fiber when pulled, optical fiber and sealing member contact surface have than larger, and seal
When part is straight-tube shape, optical fiber is pulled, and it only has one end of sealing member port with the contact surface of sealing member, it is easy to light
Fibre causes wear-out failure, this device to protect optical fiber.The cover plate of this device is rounded, and cover plate is completely covered all of sealing
Part, the stone being dropped so as to avoid sealing member pounds disconnected, and the side end of circular cover is not easy to be smashed, it is difficult to expose close
Sealing, strengthens the protection to sealing member.
Further, above-mentioned sealing member and the integrated connection of housing.Sealing effectiveness is ensure that at sealing member and housing.
The invention has the beneficial effects as follows：
（1）Sealing member design is L-shaped, and port is down, it is therefore prevented that dust is accumulated in port, it is therefore prevented that O-ring contaminates dirt, keeps away
Exempt from after maintenance, then during mounting O-shaped rings, need the step of cleaning O-ring guarantee sealing, save the time；
（2）The cover plate of this device is rounded, and cover plate is completely covered all of sealing member, is dropped so as to avoid sealing member
Stone pound disconnected, and the side end of circular cover is not easy to be smashed, it is difficult to expose sealing member, strengthens the protection to sealing member
Dynamics..
