Background

The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art.

Twisted pair (commonly known as mesh) is the most common transmission medium in integrated engineering, and consists of multiple pairs of two copper wires with insulating protective layers. Two insulated copper wires are twisted together according to a certain density, and the electric wave radiated by each wire in transmission can be counteracted by the electric wave emitted by the other wire, thereby effectively reducing the degree of signal interference. With the development of technological progress, service types and quantity, more twisted pairs are often required to be accessed to carry new services when network equipment is put into operation, twisted pairs are required to be arranged in cable ducts, and the arranged twisted pairs often need to cross places such as underdrains, underdrains and the like. The construction places are narrow in space, and a lot of inconvenience is brought to construction.

In the process of laying the twisted pairs, the inventor finds that the cover plate of the cable trench of a part of transformer substations is heavy and is not easy to lift, and the cable trench of the individual transformer substations is not provided with a cover plate at a cross-room position. Aiming at the first phenomenon, constructors do the method that the cover plate between two screen positions is completely lifted, and then the network cable is laid; for the second phenomenon, a constructor borrows a PVC pipe of about 4 meters, and winds the twisted pair on the PVC pipe by using an insulating tape, so as to transfer the twisted pair from one end of the cable trench to the other end. Two kinds of ways work efficiency are lower more, and constructor need pay out huge physical power, and extravagant material, and the work of laying soft cable is carried out the difficulty.

The working process of the guide rod of the invention is as follows:

when the device works, the tail sleeve 2 is firstly extended out, the tail end of a twisted pair to be laid is inserted into the sleeve 3, meanwhile, the clamping structure 4 is pressed down, the tail end of the twisted pair penetrates into the cylindrical structure 6, after the tail end of the twisted pair passes through, the clamping structure is loosened, the clamping structure is rebounded by means of the elasticity of the spring 5, and the first clamping plate of the clamping structure and the inner wall of the sleeve 3 cooperatively clamp the twisted pair;

then the end sleeve 2 of the guide rod extends to one end of the blind ditch and the blind groove, when the guide rod moves in the blind ditch, the LED lamp 7 can be turned on, and a normally bright or flashing working mode is selected, so that the condition in the blind ditch can be observed conveniently or the end position of the guide rod can be judged conveniently, the number of the sections of the operating rod 1 can be adjusted according to the length of the blind ditch and the blind groove until the other end of the blind ditch and the blind groove can touch the twisted pair by hands;

and finally, pressing the clamping structure 4 again by hands to draw out the twisted pair from the sleeve 3, simultaneously taking back the guide rod from the inlets of the blind ditch and the blind ditch, and shrinking each section of sleeve to the shortest, namely finishing the work of laying the twisted pair in the whole blind ditch and the blind ditch.

The guide rod disclosed by the invention is used for carrying out practical tests, the twisted-pair cables can be quickly laid from one end of the cable channel to the other end, the same network cables are laid in the same environment, and the wiring time can be saved by using the guide rod.

The guide rod is particularly suitable for working scenes of laying soft cables in cable ditches, blind ditches and the like, can meet the requirement of short-distance cover plate-free channel rapid construction, has obvious advantages in construction in a channel with a heavy cover plate, and can conveniently and rapidly convey the network cable to the other end from one end by only lifting screen positions at two ends when facing a large cover plate of the cable ditch, thereby greatly reducing the physical effort of construction of members of a team. The cable trench cover plate in the transformer substation is usually large in weight and large in quantity, the soft cable is laid from one end of the groove to the other end by using the guide rod, the opening of the middle cover plate of the groove can be omitted (the advantage of the condition that the middle part of the groove cannot be opened is particularly obvious), a large amount of manpower is saved, and meanwhile, the risk that a constructor opens the cover plate to crush and crush the hands and feet is effectively avoided.

The guide rod can be used for multiple times after being manufactured once, and the multi-section structure of the guide rod is convenient to carry, can adjust the length and can adapt to various application scenes. The guide rod effectively reduces the workload of laying cables in the cable channels of the substation of members of the team in popularization and use, effectively saves the use amount of resources such as PVC pipes and insulating tapes, and greatly improves the working efficiency. Statistical test data show that the working efficiency can be improved by 60% when cables are arranged in the groove with the middle part lacking the opening condition, and the working efficiency can be improved by about 40% when the cables are arranged in the large cover plate and the middle openable groove.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
