Description

Technical Field

[0001] The utility model relates to the technical field of line protection, in particular to a line safety protection device for a power station. Background Art

[0002] Line safety protection devices used in power stations play a vital role in ensuring the stable operation of power systems. Some of the lines are exposed to the air, and their performance is easily affected by the environment. They may be damaged externally due to friction and other conditions, thus affecting the safety and stability of the subsequent use of the lines. Therefore, safety protection devices need to be installed on the outside of the lines to ensure the safety of the lines used in power stations.

[0003] A safety protection device for an optical cable line disclosed in the Chinese utility model patent application disclosure specification CN206594344U adopts a protective outer shell and an elastic inner sleeve to physically isolate various obstacles and optical cables from suspension wires to protect the optical cables and suspension wires. At the same time, the elastic inner sleeve tightly surrounds the optical cables and suspension wires, which can not only reduce various impacts caused by friction and ensure the normal transmission of communication signals in the optical cable, but the overall functionality of the line safety protection device is relatively low. When the internal wires are subjected to the force generated by pulling, the external wires may be damaged or the connection between the wires and the protection device may become loose, thereby affecting the overall safety and stability of the line safety protection device.

At this time, the slider 202 slides on the sliding rod 201, which can squeeze the first spring 203 on one side, and due to the reaction force of the squeezing of the first spring 203, the first connecting seat 3 can be pushed to reset through the sliding rod 201.

[0024] The wire passing mechanism 4 includes a wire passing groove 401 arranged in the middle position inside the first connecting seat 3, and empty grooves 402 are arranged on both sides of the wire passing groove 401. A roller 403 is rotatably connected to the middle position inside the empty groove 402.

At the same time, a roller 403 is arranged inside the empty groove 402 to bend the transmission line 5, so as to prevent the transmission line 5 from being damaged by force due to thermal expansion and contraction.

[0025] Embodiment 2

[0026] The main difference from the first embodiment is:
