Description
Technical field
The present invention relates to the allocated transmission electro-technical field, particularly relate to a kind of totally enclosed underground cable feeder pillar.
Background technology
Cable branch box is a kind of equipment that is used for power supply is carried out distribution.At present, most cable branch box all is mounted on the ground, has not only taken expensive day by day urban ground area but also very not attractive in appearance, in addition, people's life security has also been caused certain threat.
Patent 200620036324.1,200810025777.8 with 200820145643.5 a kind of scheme that can solve above-mentioned defective has been proposed all, but all there is problem to a certain degree in the three, common ground such as: patent 200620036324.1 and 200810025777.8 is to use cable plug and needs prefabricated cement pit, 20081005777.8 need to use drainage system, once drainage system breaks down, cable end just might go wrong, secondly, the seal gasket that above-mentioned patented product uses is a normal pressure, main purpose is to prevent that outside water from entering casing, and the sealing of the product of invention use now is a negative pressure, mainly is that anti-inner insulating material such as pitch or silicon rubber leak outside; Patent 200820145643.5 also needs to use prefabricated cement box or Big Iron, and volume is excessive, and cost is too high.
Because the above defective is necessary the design of buried cable branch box is proposed new requirement.
Summary of the invention
At the problems referred to above, the invention provides a kind of totally enclosed underground cable feeder pillar.
The technical scheme that the present invention is adopted for its technical problem of solution is:
A kind of totally enclosed underground cable feeder pillar, comprise tank body, insulated column, be located at capping and inlet wire cable and outlet cable on the tank body, it is characterized in that: be filled with insulating material in the described tank body, tank wall is provided with pipeline, the port of described pipeline is provided with a mounting flange and a loose flange that fixes with inner-walls of duct, and described inlet wire cable and outlet cable pass in mounting flange and loose flange.
As further improvement of these options, described insulated column upper surface is provided with metal bar, and lower surface is provided with the installation screw rod, is with connecting ear on the described metal bar, and described inlet wire cable links to each other by the metal bar of lead with the insulated column upper surface with the outlet cable.
Further, be provided with seal gasket between described mounting flange and the loose flange.
Further, be equipped with screw on described mounting flange and the loose flange, both fix by screw.
Further, described insulating material is pitch, silicon rubber or vaseline.
In addition, described tank body is stainless steel, fiberglass or plastics.
The invention has the beneficial effects as follows: (1) volume is little, cost is low, the present invention is as a kind of totally enclosed underground cable feeder pillar, after in tank body, loading encapsulating material, cover capping, pipe end is directly fixed with flange after seal gasket is installed, removed the design of externally adding prefabricated cement pit or iron case commonly used on the market at present from, volume energy reduces more than 2/3, and cost reduces greatly; (2) waterproof damp proof effective, respond to withstand voltage height, tank body of the present invention is for being stainless steel, fiberglass or plastics, in tank body, use insulating material to load the joint portion that can terminate in the water resistance of outside tank body and insulator, can play the damp proof effect of good waterproof, and it is withstand voltage to use insulating material can effectively improve induction of the present invention; (3) save soil, beautifying city, the present invention is embedded in underground use, can either save land area, and reduces the interference of external environment, can beautify the environment again, and this seems particularly outstanding and valuable in land resource city in short supply day by day; (4) strong, the good sealing effect of anti-negative pressure performance, the seal gasket that traditional product is used is a normal pressure, main purpose is to prevent that outside water from entering casing, and the sealing means that the present invention uses is the negative pressure type, mainly be that anti-inner insulating material such as pitch or silicon rubber leak outside, reached hermetic effect; That the present invention has reached is totally-enclosed, all insulation, tangible, the premium quality product that can move in rivers,lakes and seas, possesses good prospects for application.
