DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0031] Reference Figure 1 , 3 4. A mesh-sheathed armored optical cable comprises a junction box mechanism 3, a junction box mechanism 2 and a cable mechanism 1.

The water-blocking sleeve 102, water-blocking filling layer 104, and loose tube 107 ensure that the installation environment of the optical fiber 108 is dry, reducing the impact of the humid installation environment on the implementation effect. The central reinforcement member 109 increases the strength of the optical cable and reduces the probability of damage to the optical fiber 108 due to geological movement or human factors.

[0033] Reference Figure 2 The junction box mechanism 2 includes an optical fiber junction box 201, an installation cavity 202 is arranged at the bottom of the optical fiber junction box 201, and a heat conduction mechanism 4 and an underground strain gauge 8 are installed inside the installation cavity 202. The underground strain gauge 8 detects the bending change of the optical fiber 108 of the measured section by detecting the optical cable 106, so as to ensure that when the optical fiber 108 is bent and damaged due to geological or human factors, the staff can detect the damaged section in time and perform maintenance.

[0034] Reference Figure 2 The heat conduction mechanism 4 includes a heat conduction box 401, which is installed at the bottom of the optical fiber junction box 201. The heat conduction box 401 is filled with dielectric oil. A plurality of heat conduction plates 402 are fixedly connected to the bottom of the heat conduction box 401. The plurality of heat conduction plates 402 are arranged in parallel and evenly, and the lower ends thereof penetrate the heat conduction plates 402 and contact with the underground soil. Temperature sensors 403 are installed on both sides of the heat conduction box 401. Both sides of the heat conduction box 401 are connected and penetrated with the oil pipes 105 inside the cable mechanism 1. Among the oil pipes 105 on both sides of the heat conduction box 401, one oil pipe 105 is responsible for oil transportation, and the other is responsible for oil intake, so that the heat conduction box 401 is in a circulation state. The temperature of the dielectric oil can be detected by the temperature sensor 403, and the excessively high temperature can be introduced into the underground through the heat conduction plate 402, thereby achieving a cooling effect.

[0035] Reference Figure 3 The junction box mechanism 3 includes an optical fiber junction box 301, a flow cavity 302 is provided at the bottom of the optical fiber junction box 301, and a storage mechanism 5 is installed inside the flow cavity 302. The two junction box mechanisms 2 are installed and connected through the cable mechanism 1, and the junction box mechanism 3 and the junction box mechanism 3 are installed and connected through multiple groups of junction box mechanisms 2 and cable mechanisms 1, so as to ensure the continuity of information transmission and facilitate segmented maintenance of the cable mechanism 1.

The oil pumping box 501 slowly transports the medium oil in the cable mechanisms 1 on both sides to the inside of the oil pumping box 501 or slowly pushes it out of the oil pumping box 501 through the power mechanism 6 and the pressure plate mechanism 7, thereby maintaining the power of medium oil transmission.

[0037] Reference Figure 3The power mechanism 6 includes a motor 601, which is installed on the top of the oil pumping box 501. The output end of the motor 601 passes through the top of the oil pumping box 501 and is fixedly connected to a threaded rod 602.

When the power mechanism 6 is started, the motor 601 drives the threaded rod 602 to rotate, and the threaded rod 602 drives the pressure plate mechanism 7 to move up and down. It should be noted that the threaded rod 602 rotates slowly, so as to ensure that the medium oil inside the oil pipe 105 can flow slowly.

[0038] Reference Figure 3 The pressing plate mechanism 7 includes a threaded block 701, which is threadedly connected to the threaded rod 602. An isolation plate 702 is fixedly connected to the bottom of the threaded block 701, and the radius of the isolation plate 702 is the same as the inner radius of the oil pumping box 501. When the threaded rod 602 indirectly drives the isolation plate 702 to move upward, the oil pipe 105 at the bottom delivers oil to the inside of the oil pumping box 501, and the oil pipe 105 at the top delivers oil to the outside of the oil pumping box 501.

[0039] Working principle: the outer sheath 101 provides sufficient damage resistance and anti-ultraviolet effect, and the installation environment of the optical fiber 108 is ensured to be dry through the water-blocking sleeve 102, the water-blocking filling layer 104, and the loose tube 107, so as to reduce the influence of the wet installation environment on the implementation effect, and the strength of the optical cable is increased through the central reinforcement 109, so as to reduce the probability of the optical fiber 108 being damaged by geological movement or human factors. The underground strain gauge 8 detects the bending change of the measured section optical fiber 108 by detecting the optical cable 106, so as to ensure that when the optical fiber 108 is bent and damaged due to geological or human factors, the staff can timely detect the damaged section and perform maintenance. In the oil pipes 105 on both sides of the heat-conducting box 401, one oil pipe 105 is responsible for oil transportation, and the other is responsible for oil intake, so that the heat-conducting box 401 is in a circulation state, and the temperature of the medium oil can be detected by the temperature sensor 403, and the excessive temperature can be introduced into the ground through the heat-conducting plate 402, so as to achieve the effect of cooling. The two junction box mechanisms 2 are installed and connected through the cable mechanism 1, and the junction box mechanisms 3 and the junction box mechanisms 3 are installed and connected through multiple groups of junction box mechanisms 2 and cable mechanisms 1, so as to ensure the continuity of information transmission and facilitate the segmented maintenance of the cable mechanism 1;

[0040] The oil pumping box 501 slowly transports the medium oil in the cable mechanisms 1 on both sides to the inside of the oil pumping box 501 or slowly pushes it out of the oil pumping box 501 through the power mechanism 6 and the pressure plate mechanism 7, thereby maintaining the power of medium oil transmission. When the power mechanism 6 is started, the motor 601 drives the threaded rod 602 to rotate, and the threaded rod 602 drives the pressure plate mechanism 7 to move up and down. It should be noted that the threaded rod 602 rotates slowly, thereby ensuring that the medium oil inside the oil pipe 105 can flow slowly. When the threaded rod 602 indirectly drives the isolation plate 702 to move up, the oil pipe 105 at the bottom transports oil to the inside of the oil pumping box 501, and the oil pipe 105 at the top transports oil to the outside of the oil pumping box 501. When the threaded rod 602 indirectly drives the isolation plate 702 to move down, the oil pipe 105 at the bottom transports oil to the outside of the oil pumping box 501, and the oil pipe 105 at the top transports oil to the inside of the oil pumping box 501.
