Description
Technical field
The utility model relates to a kind of aerial cable, is specifically related to a kind of deicing or snow melting device that is used for aerial cable, and described cable specifically comprises power cable, data copper cable, optical cable and radio frequency cable (being coaxial cable) etc.
Background technology
Cables such as power cable, data copper cable, optical cable and radio frequency cable usually transmit by aerial cabling mode, perhaps cross over traffic main artery, critical facility and pass through electric devices such as transformer, contact line.Aerial cabling generally be between two wire bars or iron tower by setting up the steel strand wire of a tensioning, and utilize cable clip that cable is suspended on the steel strand wire below, to finish the transformation task of electric power or signal.When yet the back air humidity of snowing in the winter time was big again, built on stilts cable was very easily icing, after cable freezes cable was born a heavy burden, and it bears a heavy burden when in a single day surpassing the tensile strength of cable itself, and cable just can be broken; Broken if support the electric pole of cable or the cable of iron tower one side, electric pole or iron tower have lost balance immediately and may pulled off, collapse by the opposite side cable at any time.Above-mentioned accident the lighter causes electric power or communication interruption, and weight person will cause cable resident's along the line loss of life or personal injury, building damage and property loss.In that snow disaster at 2008 beginning of the years, just, the ice and snow on the cable collapses in a large number because of covering the overweight iron tower that causes, make south electric network and the information communication state that once paralysing, cause the direct economic loss of state's electricity electric power to reach 3.52 hundred million yuans, the communication industry direct economic loss is up to 1,200,000,000 yuans.If change whole cables of south electric network, the electric pole and the iron tower of carrying cable, then need spend great amount of manpower and material resources and fund.
Therefore, how to develop a kind of deicing or snow melting device of built on stilts cable, under the prerequisite of not changing existing cable, solve the problem that built on stilts cable easily breaks because of ice and snow in the winter time, become the top priority of power industry.
Summary of the invention
The utility model provides built on stilts light/cable deicing or snow melting device, its objective is that aerial cable is easily because of the icing technical problem that is pressed down when solving winter.
For achieving the above object, the technical solution adopted in the utility model is: a kind of built on stilts light/cable deicing or snow melting device, form by heat-conducting plate, electrical heating elements and junction button; On the side plate face of described heat-conducting plate electrical heating elements is set, heat-conducting plate is that the inboard is wound into cylindrical tube with the plate face that is provided with electrical heating elements, form one light/cable containing cavity in inside with this, described junction button acts on the reeling condition of location heat-conducting plate on the heat-conducting plate.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described electrical heating elements comprises the various electric heating devices on the existing market, and as heating wire etc., but the best is to adopt following two kinds of schemes:
A, described electrical heating elements are that PTC encloses from the temperature control heating, and its outer wall and heat-conducting plate inboard are close to; And the conductor length direction of PTC in temperature control heating circle is axial consistent with above-mentioned light/cable containing cavity.Described PTC evenly establishes the cast heater element that lead constitutes in the temperature control heating is enclosed exactly with the positive temperature coefficient effect ptc material;
B, described electrical heating elements are many permanent power heating cable, and each permanent power heating cable length direction is axial consistent with above-mentioned light/cable containing cavity, and evenly distributed on the heat-conducting plate medial surface.
2, in the such scheme, described heat-conducting plate can be a flexible flat, as: leather sheath, flexible metal sheet etc., or cross sectional shape own is the elastic plate of circular arc or open loop circle.
3, in the such scheme, dual-side is folded mutually along extending relatively under the described heat-conducting plate reeling condition, and it splices mutually and touches the buckle structure that the face correspondence is provided with the concavo-convex cooperation of male and female, and this male and female embossed card buckle structure is above-mentioned junction button.Described junction button is meant that all can reach fixedly heat-conducting plate, the fastening structure that is wrapped in light/cable periphery wall that heat-conducting plate can be stabilized, as: snap close, hasp, the collar, rope system etc.
4, in the such scheme, described heat-conducting plate is that cross sectional shape is the elastic plate of circular arc or open loop circle, and the outer surface of this elastic plate is provided with circumferentially annular corrugated.Described annular corrugated effect is to make this device in the coiling of being more convenient for of time spent not, so that transportation and storage.
The utility model design principle is: the utility model is to establish heat-conducting plate it is wrapped up on the periphery wall of existing light/cable, and adds electrical heating elements between the two.Just can power on to electrical heating elements is logical at snowfall weather according to weather forecast during use, it just produces heat automatically and conducts to heat-conducting plate, keeps the steady temperature of heat-conducting plate outer surface, reaches the effect of automatic deicing or snow melting.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, uses the utility model, can under the prerequisite of not changing existing cable, solve the problem that built on stilts cable easily breaks because of ice and snow in the winter time, saved light/cable upgrade cost greatly.
2, when not snowfall weather uses the utility model, can stop power supply, not loss electric energy to its electrical heating elements.
3, because the utility model electrical heating elements adopts PTC from temperature control heating circle or permanent power heating cable, though increase the weight of because of the total weight that adds the heater element optical cable may have slightly, but also has the lead core in the electrical heating elements (being that PTC is from temperature control heating circle or permanent power heating cable) itself, the lead core has the tension effect, therefore, the whole resistance to tension of optical cable is still kept.
4, because the utility model is coated on light/cable when using, equal to have put on extra protective jacket, light/cable is also had protective actions such as antiultraviolet, rainproof, protection against the tide to light/cable.
