Abstract
The invention relates to an optical fiber releasing device of underground coal mine mobile equipment. The device comprises an outer lead pipe, an outer cover, an optical fiber coil, an arc-shaped deconcentrator, a mobile equipment shell, a leading-in device and a lower barrel body; the device is provided with one cylindrical lower barrel body and one cylindrical outer cover matched with the lower barrel body; the lower barrel body is internally provided with the optical fiber coil; one convex and semi-spherical arc-shaped deconcentrator is arranged at the center of the lower barrel body; the arc-shaped deconcentrator is internally provided with the leading-in device; the mobile equipment shell is arranged at the bottom of the lower barrel body; and the upper part of the outer cover matched with the lower barrel body is provided with the outer lead pipe with a 90-degree elbow. According to the optical fiber releasing device of the underground coal mine mobile equipment, the underground coal mine mobile equipment can smoothly release optical fibers in the moving process when bearing the optical fibers with a certain quantity and has a very good anti-explosion performance.
Description
Technical field
the present invention relates to a kind of mobile device optical fiber releasing means, especially a kind of underground coal mine mobile equipment optical fiber releasing means.
Background technology
underground coal mine circumstance complication, all underground communication equipment must adopt explosion-proof type, preferentially adopts essential safe type, meets national standard and " safety regulations in coal mine " requirement.Meanwhile, the rock of underworkings wall surface and texture of coal seam make Electromagnetic Wave Propagation cause serious decay.Simultaneously, the main environment propagated is the lane space of limited non-free, and the trend in tunnel is not straight line, turn round many, turnout is many, be distributed in again different surface levels, and in tunnel, stack various object and down-hole electromechanical equipment, these constitute the singularity of down-hole radio wave propagation, therefore for underworkings, the wireless telecommunications of long distance are adopted to have difficulties.At present, downhole communication is based on wire communication, and optical-fibre communications equipment is a kind of prevailing model of present down-hole wire communication.For place's mine in normal state, its communication optical fiber will have been laid when construction mine often, but after having an accident, the optical fiber laid in advance is often destroyed; Also or for needing the communication apparatus carrying out movement in down-hole, especially small-sized mobile device, the reason because of himself power does not possess the ability of drag cable or optical fiber yet, and because the singularity of optical fiber, is not suitable for pulling optical fiber.Therefore down-hole Communication in above two kinds of situations in the urgent need to address.
Summary of the invention
the Communication of electromechanical equipment when the optical fiber laid in advance to solve down-hole suffers to destroy afterwards or electromechanical equipment needs to move, consider the explosion-proof demand of the shortcoming that light inconvenience pulls and its electromechanical equipment, the invention provides a kind of underground coal mine mobile equipment optical fiber releasing means, this device effectively can solve colliery downhole equipment and bears the optical fiber of some and discharge smoothly in moving process, and has good explosion-proof performance.
the technical solution adopted for the present invention to solve the technical problems is: this underground coal mine mobile equipment optical fiber releasing means comprises: outer skirt, outer cover, optical fiber cable bag, arc deconcentrator, mobile device shell, introducing device, lower shell; This device has a columnar lower shell fixing for optical fiber cable bag, and with the cylindrical outer cover of lower shell joint match; Lower shell inside is provided with optical fiber cable bag, lower shell center is provided with the arc deconcentrator of a protruding hemisphere bodily form, prevent optical fiber in the process of taking out optical fiber from twisting on introducing device, arc deconcentrator is provided with in inside and makes introducing device through inside and outside lower shell, for the extraction of optical fiber one end, and can be explosion-proof; Be provided with mobile device shell bottom lower shell, mobile device shell is provided with the hole coincide with introducing device, for the extraction of optical fiber another end line; The outer cover mated with lower shell, is provided with an outer skirt with 90 degree of elbows on the top of outer cover, one end of optical fiber is drawn from lower shell.During use, be placed on by optical fiber cable bag in lower shell 9, optical fiber two ends are drawn respectively from outer skirt 2 and introducing device 8.
the invention has the beneficial effects as follows: this underground coal mine mobile equipment optical fiber releasing means can effectively solve optical fiber that underground coal mine lays in advance suffer to destroy after or electromechanical equipment needs to move time electromechanical equipment Communication.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the present invention is further described.
fig. 1 is the vertical section structure schematic diagram of underground coal mine mobile equipment optical fiber releasing means.
in Fig. 1,1. optical fiber, 2. outer skirt, 3. outer cover, 4. optical fiber another end line, 5. optical fiber cable bag, 6. arc deconcentrator, 7. mobile device shell, 8. introducing device, 9. lower shell.
