Abstract

The utility model relates to a cable protection pipe, which comprises two semicircular pipes, wherein the two semicircular pipes can be combined for forming a circular pipe, and tongue-and-grooves and rabbets which are mutually matched are formed on the axial semicircular pipe edges for connecting the two semicircular pipes. The utility model is characterized in that the circular pipe is circulated by the two semicircular pipes through an annular hoop provided with a fastening element, cables which are downwards led to the underground from an above transformer platform along a telegraph pole in a standard power distribution station can be covered in the circular pipe formed through combination, and the semicircular pipe edges for connecting the two semicircular pipes are engaged through the tongue-and-grooves and the rabbets which are mutually matched, so the cable protection pipe has the finished and smooth appearance and has the intensity of the circular pipe. When the cable protection pipe is replaced, and the cables led into the underground need to be maintained, replaced or moved, the fastening element of the annular hoop is unfastened, the two semicircular pipes can be separated, the cables can be taken out, the cable protection pipe can be conveniently replaced, the cables led into the underground can be conveniently maintained, replaced or moved, and the cables do not need to be damaged.

Description

Cable protection pipe

Technical field

The utility model relates to the tube wall of a kind of cable protection pipe, particularly a kind of cable protection pipe.

Background technology

In some standard distributed transformer station; have from the transformer platform of top and introduce underground cable downwards along electric pole; introducing underground cable is in the people's activities scope; in people's activities; take place sometimes because of damaging the accident of cable with the underground cable scratching of introducing; in order to protect the underground cable of from transformer platform along electric pole introducing, cable protection pipe is arranged at cable jacket not because of damaged by scratching.In the prior art; the cable protection pipe that is enclosed within on the underground cable of from transformer platform along electric pole introducing is the steel pipe of whole pipe wall such as seamless steel pipe or ratio-frequency welded tube; this cable protection pipe is owing to be the steel pipe of whole pipe wall; when the cable in if cable protection pipe need be changed or manage needs repairing, changes or moves; because an end of cable has cable end; so the cable in the pipe can not be extracted out in cable protection pipe fully; when changing cable protection pipe and maintenance, replacing or migration and introduce underground cable, need to destroy cable.

Summary of the invention

The purpose of this utility model is in order to overcome above-mentioned deficiency, proposes a kind ofly when changing cable protection pipe and maintenance, replacing or migration and introduce cable in the buried pipe, does not need to destroy the cable protection pipe of cable.

The utility model is realized with the following method.

Cable protection pipe has two to combine and can become the semicircle of pipe pipe, and the axial semicircle tube edge that two semicircle pipes are connected has tongue-and-groove or the rabbet that matches.

During use; two semicircle pipes of the present utility model are available to have the annular anchor ear of securing member to surround pipe; the axial semicircle tube edge that is connected owing to two semicircle pipes has tongue-and-groove or the rabbet that matches; after surrounding pipe; the tongue-and-groove or the rabbet of the semicircle tube edge that two semicircle pipes are connected mesh together; can radial-play between two semicircle pipes, make cable protection pipe after the merging keep polishing, slick and sly outward appearance and the intensity of pipe.

The utility model is the pipe that surrounds with the effective annular anchor ear that securing member arranged of two semicircles; can introduce underground cable to standard distributed transformer station downwards from the transformer platform of top along electric pole wraps in and merges in the pipe that forms; the semicircle tube edge that two semicircle pipes are connected meshes together with the tongue-and-groove or the rabbet that match; make cable protection pipe have polishing; the slick and sly outward appearance and the intensity of pipe; changing cable protection pipe and maintenance; change or move when introducing underground cable; open the securing member of annular anchor ear; can make two semicircle pipes separately; take out cable; be convenient for changing cable protection pipe and maintenance; change or move and introduce underground cable, do not need to destroy cable.

Below in conjunction with accompanying drawing, the utility model is further described.

In two axial semicircle tube edges of above-mentioned semicircle pipe, on the axial semicircle tube edge tenon is arranged, on another axial semicircle tube edge groove is arranged.Axially the semicircle tube edge cooperates in two semicircle pipes that are connected with tongue-and-groove, and also can be has tenon on two axial semicircle tube edges of a semicircle pipe, on two axial semicircle tube edges of another semicircle pipe groove is arranged.

Among Fig. 3, axially the semicircle tube edge cooperates in two the

semicircle pipes

7,8 that are connected with tongue-and-groove, on two axial semicircle tube edges 9 of a semicircle pipe 7 tenon 10 is arranged, and on two axial semicircle tube edges 11 of another semicircle pipe 8 groove 12 is arranged.

The axial semicircle tube edge that above-mentioned two semicircle pipes are connected has tenon and the groove that matches.The axial semicircle tube edge that two semicircle pipes are connected also can have the rabbet that matches.The rabbet of the axial semicircle tube edge that two semicircle pipes are connected can be symmetry also can be in the same way.

Among Fig. 3, the axial semicircle tube edge that two

semicircle pipes

13,14 of cable protection pipe are connected has the

rabbet
