Underground optical fiber positioning detection device

Abstract

The invention belongs to the technical field of optical fiber positioning detection, and particularly relates to an underground optical fiber positioning detection device. The device comprises an underframe, a mounting frame, and a handle fixedly connected to the outer surface of the underframe, wherein a detector is fixed on the upper surface of the mounting frame through screws; a plurality of sliding connecting grooves are formed in the inner wall of the mounting frame; the mounting frame is slidably connected with a protective cover through the multiple sliding connecting grooves; a slotted hole is formed in the lower surface of the protective cover; meanwhile, a sliding connecting groove is formed in the upper surface of the mounting frame; the protective cover can be conveniently mounted on the upper surface of the mounting frame through the sliding connecting groove; therefore, when the detector moves to work, the detector can be conveniently and safely protected on the outer surface of the detector, the hole groove is formed in the lower surface of the protective cover, when the detector is used and makes a sound, the sound can be transmitted out through the hole groove inthe lower surface of the protection cover, and then a leakage hole protection net is arranged to protect the hole groove in the lower surface of the protective cover.

Description

technical field [0001] The invention belongs to the technical field of optical fiber positioning detection, and in particular relates to an underground optical fiber positioning detection device. Background technique [0002] The optical fiber is encapsulated in a plastic sheath so that it can be bent without breaking. Usually, the transmitting device at one end of the fiber uses a light-emitting diode or a laser beam to transmit light pulses to the fiber, and the receiving device at the other end of the fiber uses a photosensitive element to detect Pulse, in daily life, because the transmission loss of light in optical fibers is much lower than that of electricity in wires, optical fibers are used for long-distance information transmission, and optical fibers play an important role in modern society. Optical fibers are used in maintenance Positioning detection is required in the process. The existing Chinese invention patent No. CN201310366155.2 solves the problem of detect...

[0002] The optical fiber is encapsulated in a plastic sheath so that it can be bent without breaking. Usually, the transmitting device at one end of the fiber uses a light-emitting diode or a laser beam to transmit light pulses to the fiber, and the receiving device at the other end of the fiber uses a photosensitive element to detect Pulse, in daily life, because the transmission loss of light in optical fibers is much lower than that of electricity in wires, optical fibers are used for long-distance information transmission, and optical fibers play an important role in modern society. Optical fibers are used in maintenance Positioning detection is required in the process. The existing Chinese invention patent No. CN201310366155.2 solves the problem of detecting optical fibers on the ground, but it still has some inconvenience in use. When performing optical fiber positioning detection on the surface, it often Affected by surface debris, it is inconvenient to locate and detect the optical fiber, and when detecting in different terrains, it is often affected by surface water or other factors, which makes the detection limited
