Description
Technical field
The utility model relates to the instrument of the central transmission line security maintenance of a kind of power industry, particularly a kind of guiding clamp system of ground wire deicing device.
Background technology
Transmission line icing in the winter time is one of natural calamity of electric power system.Particularly rare ice and snow disaster in 2008 has caused the most serious since the dawn of human civilization destruction to nationwide integrated power grid, and situation such as shaft tower collapses, line interruption, transformer station's stoppage in transit appear in a lot of areas.At present, the transmission line de-icing method that has proposed both at home and abroad has: thermal ice-melting method, mechanical deicing's method, natural passive means etc., these method complex operations, deicing cost height are not suitable for large scale application.Especially these de-icing methods all are not suitable for the ice formation issues of 350kV ultra-high-tension power transmission line ground wire.Therefore, the development of ground wire deicing device is imperative, solves ice-melt in the winter problem of 350kV high-tension line with less cost.
The utility model content
The utility model is in order to solve weak point of the prior art, and a kind of guiding clamp system of simple in structure, easy to operate, with low cost, the ground wire deicing device that is specially adapted to the 350kV high-tension line is provided.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: the guiding clamp system of ground wire deicing device; Comprise connecting cylinder, be located at the buckling groove in the connecting cylinder, the strong magnet, the follower head that are located in the clamping cell body are the leading screw and the framework of band clamping head, and the clamping head of leading screw is located in the buckling groove and with strong magnet absorption and is connected; Leading screw is threaded with framework; The front end that leading screw extend in the framework is provided with the moving chuck of the insulation with half-arc groove, is provided with the conduction with half-arc groove in the framework and decides chuck, and the half-arc groove of the moving chuck of insulation is oppositely arranged with the half-arc groove that conduction is decided chuck.
Said connecting cylinder is provided with protective cover outward.
The internal structure of said buckling groove is that six prisms, rear portion are the cylindrical shells of cylinder-like structure for the front portion, and the clamping head is for axially being plugged in six prism structures in the cylindrical shell.
Adopt technique scheme, connecting cylinder inside and outside outer respectively install cylindrical shell and nylon cover, circular hole is processed at the cylindrical shell rear portion; Lay strong magnet; Strong magnet is used for being connected with leading screw, and cylindrical shell is pegged graft with six of leading screw prismatic terminations and cooperated, and avoids leading screw to rotate; The effect of protection connecting cylinder and cylindrical shell has been played in effect with reliable guiding and location, nylon cover.The internal structure of buckling groove is that six prisms, rear portion are the cylindrical shells of cylinder-like structure for the front portion; The clamping head is for axially being plugged in six prism structures in the cylindrical shell; Attraction through strong magnet is fixed on the clamping head in the buckling groove, plays good guiding and positioning action, can also conveniently install and shirk.
The utility model is simple in structure, and is novel in design unique, convenience quick for installation, and attachment security is reliable, long service life, is prone to installation and maintenance, can be widely used in the ground wire deicing of transmission line.
