Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies of the current technology, to provide a fixed frame for the optical transmitter in the mine, to solve the problem that the optical transmitter in the existing mine is not installed firmly, and is often hit by stones, and the service life is greatly reduced defect
And the optical fiber comes out from the outlet hole

Embodiment 1

[0018] Such as figure 1 As shown, the fixed frame of the optical transmitter in the mine includes a housing 1, the housing 1 is hollow cylindrical, the upper end is open, the lower end of the housing 1 is provided with a roller 2, and the inner wall of the housing 1 is provided with a horizontal blocking ring 3, so The barrier ring 3 is provided with a protective cover 4, and the outer peripheral wall of the lower end of the housing 1 is provided with external threads, which are threaded with a roller protection ring 5. After the roller protection ring 5 rotates downward, the roller 2 Completely wrapped inside it, the outer wall of the casing 1 is provided with a wire outlet hole 6 . This device is used to place the optical transmitter. The optical transmitter is put into the casing 1, and then the protective cover 4 is covered. The protective cover is placed on the blocking ring 3, and the optical transmitter can be put into the casing 1 from the blocking ring 3. , and the s...

Embodiment 2

[0020] Such as figure 2 , the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that the lower end of the roller protection ring 5 is a sawtooth structure, and the roller protection ring 5 is designed in a sawtooth shape, which can grip the ground more firmly and prevent the housing 1 from moving , to prevent the internal optical transmitter from colliding with the shell 1.

Embodiment 3

[0022] Such as image 3 , The structure of this embodiment is basically the same as that of Embodiment 2, except that the side end of the roller protection ring 5 is provided with a rotating handle 7, which facilitates the rotation of the roller protection ring 5. Turning the handle 7 thread is installed on the roller protection ring 5, the rotation handle 7 must be perpendicular to the roller protection ring 5, and the stone will be damaged if it hits it, so the rotation handle 7 is designed to be detachable, and it can be used again when needed. It is very convenient to install, and there is protection to turn the handle 7.

Abstract

The invention discloses a holder of an optical transmitter in mine. The holder comprises a casing which is of a hollow cylinder shape. The upper end of the casing is opened and the lower end of the casing is provided with rollers. A horizontal retainer ring is arranged on the inner wall of the casing and provided with a protective cover. An external thread is arranged on the peripheral wall of the lower end of the casing and is in threaded connection with a roller protective ring; the roller protective ring completely covers the rollers after rotating downwards. A wire outlet hole is formed in the outer wall of the casing. The casing is arranged for mounting the optical transmitter, so that the optical transmitter is prevented from being smashed by rocks falling above, and problems about mounting of the optical transmitter are avoided. The rollers arranged at the lower end of the casing are used for moving of the optical transmitter; the rollers covered with the protective ring are protected. The roller protective ring can move up and down so that the optical transmitter can be fixed effectively when the roller protective ring fits the ground.

Description

technical field [0001] The invention relates to an installation structure of an optical fiber transmitter in a mine, in particular to a fixing frame for an optical transmitter in a mine. Background technique [0002] In existing mines, the monitoring system generally transmits video signals through optical fibers, and the images are relatively clear and rarely lost. The data detected by the camera is sent to an optical transmitter, and the optical transmitter converts the electrical signal of the camera into an optical signal for transmission. , but the existing optical transmitter is fixed on the stone wall of the mine, because the ore is not compact, the transmitter is easy to fall off the stone wall, and the stones falling from the upper end often hit the transmitter, although the existing mine transmitter They are all strong explosion-proof structures, but the service life is greatly shortened in the constant impact. Contents of the invention [0003] The purpose of t...
