Description

Technical Field

[0001] This utility model relates to the field of equipment installation in coal mine goaf areas, specifically a rapid installation device for fiber optic monitoring networks in coal mine goaf areas. Background Technology

[0002] Mine safety monitoring has a significant impact on coal mine safety production. With increasing mining depth and intensity, mine ventilation systems are becoming increasingly complex. Influenced by goaf areas and existing small coal mines in the surrounding area, mines experience significant air leakage, posing serious safety hazards. Therefore, comprehensive safety monitoring of goaf areas is of paramount importance.

[0003] In existing technologies, optical fibers are often used for monitoring processes in coal mines. However, the deployment of optical fibers underground is easily affected by underground vibrations, and the deployment is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0004] The purpose of this invention is to provide a rapid installation device for fiber optic monitoring networks in coal mine goaf areas, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid installation device for a fiber optic monitoring network in a coal mine goaf, comprising a hollow anchor rod body, wherein a fiber optic body is inserted inside the hollow anchor rod body, and a plurality of guide protrusions are fixedly connected to the inner wall of the hollow anchor rod body along the axial extension direction.

[0006] Preferably, each of the guide bumps has a semi-circular cross-sectional shape and is made of rubber.

[0007] Preferably, a plurality of the guide protrusions are evenly distributed along the circumferential direction of the inner wall of the hollow anchor body, and one end of each guide protrusion near the center of the hollow anchor body is in contact with the outer side of the optical fiber body.

[0008] Preferably, an anchor head is fixedly installed at one end of the hollow anchor rod body, and a nut is threaded onto the other end of the hollow anchor rod body.

[0009] Preferably, a washer is fixedly installed at one end of the nut, and a grout stopper is fixedly installed at the other end of the washer.

[0010] Compared with the prior art, the advantages of this utility model are as follows:

[0011] This invention inserts the optical fiber body into the hollow anchor bolt body from one side. Several guide protrusions guide the insertion of the optical fiber body. At the same time, the multiple guide protrusions can buffer some of the impact of underground vibration on the monitoring process of the optical fiber body. By inserting the optical fiber body into the hollow anchor bolt body, the efficiency of the optical fiber body in underground deployment is improved, and the interference of underground vibration on the optical fiber body signal is reduced.

[0017] In this embodiment, each guide protrusion 3 has a semi-circular cross-sectional shape and is made of rubber. Several guide protrusions 3 are evenly distributed along the circumferential direction of the inner wall of the hollow anchor rod body 1. One end of each guide protrusion 3 near the center of the hollow anchor rod body 1 is in contact with the outer side of the optical fiber body 2. An anchor head 4 is fixedly installed at one end of the hollow anchor rod body 1, and a nut 7 is threaded onto the other end of the hollow anchor rod body 1. A pad 6 is fixedly installed at one end of the nut 7, and a grout stop plug 5 is fixedly installed at one end of the pad 6.

[0018] Furthermore, the optical fiber body 2 is inserted from one side of the hollow anchor body 1, and the insertion of the optical fiber body 2 is guided by several guide protrusions 3. At the same time, the multiple guide protrusions 3 can buffer some of the impact of downhole vibration on the monitoring process of the optical fiber body 2. By inserting the optical fiber body 2 into the hollow anchor body 1, the efficiency of the optical fiber body 2 in the downhole is improved, and the interference of downhole vibration on the signal of the optical fiber body 2 can be reduced. The hollow anchor body 1 is fixed in the downhole environment by the anchor head 4, the grout stop plug 5, the pad 6 and the nut 7, which has been fully disclosed in the prior art and will not be described in detail here.

[0019] The working principle of this utility model is as follows: The optical fiber body 2 is inserted into the hollow anchor body 1 from one side. Several guide protrusions 3 guide the insertion of the optical fiber body 2. At the same time, the multiple guide protrusions 3 can buffer some of the impact of underground vibration on the monitoring process of the optical fiber body 2. By inserting the optical fiber body 2 into the hollow anchor body 1, the efficiency of the optical fiber body 2 in underground deployment is improved, and the interference of underground vibration on the signal of the optical fiber body 2 can be reduced.
