Description
Technical field
The utility model relates to a kind of supply line equipment, is specifically related to a kind of power transmission line ice coating resistant device.
Background technology
That ice damage in 2008, imprints on the bones and the memory many electrical network people, and in southern area, particularly the accident of falling rod disconnection mostly appears in the mountain route of high height above sea level, has caused many places large-area power-cuts. Afterwards, state's net has strengthened power grid construction gradually, and has improved design standard, has implemented the location differentiation Anti-freezing design of portion of partial line road bureau. For preventing that line ice coating from causing the accident of falling rod disconnection again, study multiple wire alternating current-direct current de-icing technology both at home and abroad and for actual motion, technology reaches its maturity. And anti-icing, deicing measure to aerial earth wire, mainly that electric current ice-melt (is transformed into Ground wire with insulation ocver by aerial earth wire, add short circuit current ice-melt, after icing completes, need again the air gap to carry out short circuit), artificial deicing (as pulley spatula, lasso, brute force are beaten vibration etc.), all there is the phenomenons such as high cost, operating difficulties, increase security risk.
And find by that Ice Disaster in Power Grids accident in 2008, there is rod disconnection generally first from disconnected ground wire in transmission line of electricity, can learn when wire type is at LGJ-150/25 and when following from trolley line icing result of calculation, aerial condutor is than ground wire more first fracture in same ice covering thickness situation in theory, this is because the steel core of wire is less than GJ-35 ground wire, and when wire type is at LGJ-150/35 and when above, aerial earth wire is than wire more first fracture in same ice covering thickness situation in theory. After ground thread breakage, powerful impulsive force tends to break earth wire support or makes ground wire connect gold utensil and ruptures, and the post-rift steel tower of earth wire support has changed the stress balance of integral basis steel tower, thereby wire cross-arm is also occured bending and deformation, even cause fracture, thereby causing wire also ruptures, after wire fracture, can directly break wire cross-arm, even cause integral basis steel tower and also topple. Therefore, be necessary to strengthen anti-icing, the de-icing technology research to aerial earth wire.
Utility model content
The purpose of this utility model is for the problems referred to above, a kind of power transmission line ice coating resistant device is provided, solve the problem of ice covering on transmission lines, be applicable to jointless single conductor in aerial earth wire and shelves, make electric line, at icing, icing phenomenon not occur season, thereby avoid electric line because serious icing causes the accident of falling rod disconnection occurs, significantly improved electric line operation stability and reliability.
The utility model is to realize like this, a kind of power transmission line ice coating resistant device, mainly comprise base, bracing frame and rain cover, it is characterized in that being equipped with on described bracing frame the power transmission shaft of vertical direction, power transmission shaft top connects vane by rod member, described vane is hemispherical, for collecting wind-force and rotating around power transmission shaft;
Described power transmission shaft middle part has fixedly mounted upper transfer gear and lower transmissioning gear, and upper transfer gear is relative helical gear with lower transmissioning gear;
Described power transmission shaft lower end connects turn-around guide, turn-around guide is " double-barrelled shotgun " shape, a touch pole of the each extension in its both sides, its lower end is connected to base by spring bracing, and the stockbridge damper that touch pole collides on aerial earth wire can make turn-around guide promotion upper transfer gear and lower transmissioning gear upwards or move down; A upper roller compound gear being become with plane gear train by helical gear is installed on the bracing frame of a side between upper transfer gear and lower transmissioning gear, and upper roller compound gear is driven by upper transfer gear or lower transmissioning gear by turn-around guide control;
Described upper roller compound gear connects at least two above horizontal upper roller shafts by gear, a upper roller is installed on each upper roller shaft, a bottom roller is installed in each upper roller below, each bottom roller is arranged on bottom roller axle, bottom roller axle two ends are connected on base by spring strut, and upper roller and bottom roller are all the spheric of indent;
Described rain cover is arranged on base, its underpart is rectangular shape, hollow is without lower plane, top is arc, arcwall face upper driving shaft position is drilled with an aperture, on former and later two facades, cut two " n " shape doors and the aperture through turn-around guide touch pole, to be inserted in aerial earth wire and pass touch pole; Before and after rain cover, " n " shape door on two sides is pasted with hairbrush around.
On the spheric outer surface of described upper roller, there is embossing striped, can increase and the frictional force of ground wire, also can eliminate some thin ice simultaneously.
Its principle is to utilize transmission line of electricity to form weather conditions when icing (temperature-5 DEG C～0 DEG C, relative humidity is in 90% left and right, wind speed is 3～15m/s) in wind friction velocity, and utilize the vane principle that tests the speed in anemobiagraph, can be used as this device and can on aerial earth wire, walk and drive away the original driving force of glaze or rime. Under wind-force effect in any direction, three rims of a cup on vane always rotate towards a direction, and the rotation of vane can be rotated by the power transmission shaft with the vane that is dynamically connected, thereby one of them oblique gear fixing on power transmission shaft is also and then rotated, drive again the built-up gear on side also to rotate, the rotation of built-up gear drives the face gear of both sides to rotate again, from and drive and connect the roller of two face gears and also rotate, thereby the object that implement device is walked on aerial earth wire. In device walking, two groups of hairbrush that are arranged on device can brush the sleet, rime, the snow that are attached on aerial earth wire, make aerial earth wire lose " raw material " of icing, and final realization prevents the object of overhead ground wire ice coverage. Turn-around guide can make the walking of device energy automatic reverse, a touch pole of the each extension in its both sides, be placed on above the bearing bottom of power transmission shaft, and clamp power transmission shaft, utilize the spring bracing elastic force effect of below of power transmission shaft, in the time that touch pole collides the stockbridge damper on aerial earth wire, turn to guiding to march forward, thus by power transmission shaft to pressing down, make the helical gear work above on power transmission shaft, so, just walking forward of device; And in the time that device is gone to the opposite side of aerial earth wire, touch pole collides again the stockbridge damper of opposite side, turn to guiding to draw back, now, power transmission shaft loses the downforce effect of guiding device, can upwards push up because of the elastic force effect of spring support, make on power transmission shaft helical gear work below, device is just walked backward so.
The beneficial effects of the utility model are: the effect of natural climate wind-force when this device utilizes icing, without adding other power to installing, utilize vane directional rotating principle and gear mechanism transmission principle, impel this device on aerial earth wire, to walk, and utilize the reverse walking of turn-around guide implement device, in the time of device walking, the hairbrush on device just can brush the sleet, rime, the snow that are attached on aerial earth wire, thereby plays the effect that prevents overhead ground wire ice coverage.
