The present invention is when making, adopt the interior steel pipe 1 with selected internal diameter, interior steel pipe 1 is axially cut into left and right two parts and is formed two semi-steel pipes 14 along steel pipe center, every part semi-steel pipe 14 is used simultaneously fine turning lathe centrally axial car go out the cell body 14 of one or more half horn-like continuous linking, for effective fixing composite material plug; An outer steel pipe 2; it is outer through 1-1.5 millimeter that pipe interior diameter is greater than interior steel pipe 1, the inwall car of outer steel pipe 2 two ends is about the screw thread of 15-20 millimeter, goes out the external screw thread 22 of 50 millimeters along pipe outer wall middle vehicle; for steel pipe 1 in fixing and protection, fix aluminum outer sleeve 40 simultaneously.Steel anchor 5 is forged by steel material to form, comprising the oval steel loop 53 for being connected with shaft tower insulator, preventing from slipping into the external screw thread rod 51 of jam 52 and 15 millimeters long of aluminum outer sleeve 40, the outside dimension of external screw thread rod 51 is suitable for rotating the end being screwed into outer steel pipe 2.Steel termination 3 is steel material, and select through hole 31 to be greater than composite material plug 1-2 millimeter, the steel pipe Cutting Length that external diameter is equal with outer steel pipe 2 is 25 millimeters.One end car of steel termination 3 goes out the external screw thread of 15 millimeters long, is suitable for rotating the end being screwed into outer steel pipe 2, and under preventing pulling force effect, interior steel pipe 1 pulls out from outer steel pipe 2.Power transmission cable comprises the outer aluminium stranded conductor of many multilayers and interior aluminium stranded conductor is wound on a composite material plug 30, the plug peeling off one section of equivalent length extends beyond outer twisted wire, first composite material plug 30 is inserted in steel termination 3, two panels semi-steel pipe 13 is added respectively appropriate high temperature resistant anti-aging instant resin glue and (adopt EP1000A/B Epoxy Adhesive epoxide-resin glue, anti-200 degree of high temperature) after plug is put into, two panels is closed up makes plug be fixed in interior steel pipe 1; Interior steel pipe is inserted in outer steel pipe 2, steel termination 3 is rotated the first end being screwed into outer steel pipe 2, after steel anchor 5 is rotated the second end being screwed into outer steel pipe 2.The external heater of 300 degrees Celsius to 500 degrees Celsius is used to be heating and curing 10-15 minute to the connector combined; make core rod firmly in interior steel pipe 1; part resin glue can fill steel termination 3 simultaneously; play the effect of protection plug, eliminate the stress between composite material plug and outer steel pipe 2 and shearing force.An aluminum outer sleeve 40 with selected internal diameter, is slidably engaged on outer steel pipe 2, and is connected with the power transmission cable of taking measurements such as a section.Aluminum outer sleeve 40 is made up of conducting metal aluminum.The end of aluminum outer sleeve 40 connects one piece of baffler 50 along sleeve outer, uses same aluminum to make.This baffler 50 is welded on the end of aluminum outer sleeve 40 end.Aluminum outer sleeve 40 also comprises a terminal and connects power transmission cable mozzle, and this mozzle uses equal aluminum.One end is connected with cable, and the other end is connected with baffler.
The present invention uses and is made up of steel material; and the hollow steel pipe of regulation equivalent length, internal diameter interior steel pipe 1 endoporus is processed into be connected continuously horn-like and is stabilized in interior steel pipe 1 with composite material plug by the instant resin glue of high-temperature-resistant and anti-corrosion; be inserted in outer steel pipe 2; aluminum outer sleeve 40 be connected gold utensil mechanical presses compress connect time; not only play and be effectively connected with aluminum outer sleeve 40, effectively protect the composite material plug 30 of interior steel pipe 1 and inside simultaneously.Because resin glue is identical with composite material mandrel material characteristic, be combined with plug in the horn-like cavity of interior steel pipe 1 and form trumpet-shaped centrum, make composite material plug outside pulling force when cannot extract out in interior steel pipe 1.In interior steel pipe 1 installation process, the high-temperature resin glue be squeezed out in its cavity can flow in the through hole 31 of connector 32 plug wrapped by internal control, efficiently solves the stress and shearing force problem that produce between two kinds of different materials.Present invention reduces the length connecting gold utensil, solve in construction and installation process and cause the problems such as wire dropping because gold utensil is long.
For the detailed explanation of the respective embodiments described above, its object is only to make an explanation to the present invention, so that the present invention can be understood better, but, it is limitation of the present invention that these descriptions can not become with any explanation, particularly, each feature described in various embodiments also can combination in any mutually, thus form other execution modes, except there being clearly contrary description, these features should be understood to can be applied in any one execution mode, and are also not only confined to described execution mode.
