Specific embodiment:
Embodiment 1
In deicer, including with free-open-close and two semicircular cylinders of lightening core can be provided with, cylinder is evenly arranged in
3 groups of ways C-C of the radial direction of shape support 1, are evenly arranged in 3 groups of deicing component B-B of the radial direction of cylinder-shaped bracket 1, uniform cloth
Put 3 groups of align member A-A in the radial direction of cylinder-shaped bracket 1.
By setting the cylinder-shaped bracket 1 of Φ 300 × 300 × 10, can be according to uneven icing real-time adjustment telescopic extensions
Directive wheel 14, the freely adjustable ice removing wheel 15 for cutting ice depth prevents icing lead wire and earth wire axial line and deicer axial line
The locating wheel 23 of skew.Directive wheel 14, ice removing wheel 15, locating wheel 23 radially, are evenly arranged along cylinder-shaped bracket 1 in 120 degree, and
Spacing between directive wheel 14, ice removing wheel 15 and locating wheel 23 is 120mm.Have in view of lead wire and earth wire ice covering thickness uneven
Property, installing spring 9 is adjusted on ways.Ice removing wheel 15 is rotated during traveling, and excision icing or destruction are covered
The rock-steady structure of ice, the purpose of icing is removed so as to reach.Locating wheel 23 uses LY12 steel, reliable in deicing traveling process
Contact lead wire and earth wire, makes deicer keep equipotential with lead wire and earth wire.Meanwhile, locating wheel 23 coordinates with directive wheel 14, on the one hand really
Deicer axial line and icing lead wire and earth wire axis parallel are protected, is on the other hand determined that ice removing wheel 15 reaches and enough is cut ice depth
Degree, and lead wire and earth wire is not hurt.The deicer needs three people operation, without special training, is taken compared to current other unit
For deicing mode, can be prevented effectively from and the not same period occurs in ice detachment deice and lead wire and earth wire jump occurs, it is and time saving and energy saving,
Highly effective and safe, it is extremely easy to use.
Further optimization, the cylinder-shaped bracket 1 takes two semicircle steel designs, is connected using hinge 4, using butterfly
Adjusting bolt 5 can be convenient in icing lead wire and earth wire over-assemble, and stabilized structure with freely openable, is unlikely to deform.Cylinder-shaped bracket 1 is opened
There is lightening core, deicer entirety full weight is declined to a great extent, be convenient for carrying.
Embodiment 2
Directive wheel 14 uses polytetrafluoroethylmaterial material, small with thermal coefficient of expansion, the characteristics of sliding friction is big.In view of leading
Ground wire icing has inhomogeneities, and one group of spring 9, diameter of phi 2.5, the nothing in deicing traveling process are installed on the 3rd loop bar 11
How to change by ice covering thickness, the occlusion dynamics of directive wheel 14 remains equal, will not be due to the uneven of ice covering thickness
Cause to coordinate with locating wheel 23 and fail, so as to ensure that ice removing wheel 15 cuts ice depth and do not hurt lead wire and earth wire with enough.
Embodiment 3
It is the ice removing wheel 15 of deicer to use ratchet skates.Ratchet skates are improved, take rotation skates to replace
Fixed skates, while there is inhomogeneities in view of lead wire and earth wire ice covering thickness, and icing hardness is also had nothing in common with each other, typical circular turns
Dynamic skates are still susceptible to jam during traveling, therefore, the ratchet skates edge of a knife is changed to the gear shape at certain inclination angle.
Because lead wire and earth wire icing is actually the cylindrical shape of parcel lead wire and earth wire, laterally give a power more destructible its rock-steady structure, therefore,
The ratchet skates edge of a knife is changed to horizontal destruction by this example by longitudinally cutting.It is different in view of lead wire and earth wire model, the side of ratchet skates one
Face needs effective deicing, on the other hand needs to be applied to various lead wire and earth wire, before deicer is waited to run, the ratchet skates edge of a knife with
Lead wire and earth wire gap should keep 2mm.
Embodiment 4
Locating wheel 23 is in whole deicer, it is necessary to coordinate with directive wheel 14, it is ensured that deicer axial line with lead ground
Line axis parallel, and need to make deicer keep equipotential with lead wire and earth wire by the pulley.Therefore, locating wheel 23 is used
LY-12 steel make.Should be rotated in the lead wire and earth wire for removing icing in view of locating wheel 23 and moved ahead, its gap should be led
The line footpath of ground wire, the diameter is isometrical all the time, therefore, locating wheel 23 is without using the real-time regulation gap of spring 9.
