Description
Technical field
The utility model relates to a kind of deicer, particularly a kind of device for removing icing on the overhead transmission line.
Background technology
2008 the beginning of the year south China met with serious ice and snow natural calamity, the transmission system of some areas is by heavy damage.Inhomogeneous icing and do not deice the phenomenons such as conductor galloping that cause the same period and can cause the accidents such as line tripping, power failure on the transmission line; When icing is serious in addition can cause that shaft tower tilts, collapses, the substantial risk accidents such as broken string or insulator arc-over occur.Because transmission line malfunction can cause electric power system can't repair for the moment, the long-time power failure caused very big impact to industrial and agricultural production and people's life, causes a large amount of financial resources, material resources loss.Domestic at present main cable deicing method is the deicing of manually reaching the standard grade, this operating type efficient is low, dangerous large, and use the zone to be subjected to the restriction of the factors such as surrounding environment, weather, special operating personnel's operation of can't reaching the standard grade when overhead wire is heavy grade and moves towards in the steep hills district.
The utility model content
Technical problem to be solved in the utility model provides a kind of cable de-icing device based on marmem, it is not subjected to the restriction of the factors such as surrounding environment, weather, self gravitation, can walk and the deicing operation along overhead transmission line, have advantages of that deicing efficiency is high, use safety.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of cable de-icing device based on marmem, it comprises that two are placed on the flexible rubber pipe of cable periphery, two tubular shape memory alloy springs, two supporting brackets, a plurality of shape memory alloy springs and a plurality of common spring, described two supporting brackets are fixedly connected on respectively the end of two flexible rubber pipes, described two tubular shape memory alloy springs are embedded in respectively on the outer wall of two flexible rubber pipes, described a plurality of common spring is placed on correspondingly outside a plurality of shape memory alloy springs respectively and makes up, and the two ends of this sub-assembly are fastened on two supporting brackets by screw bolt and nut respectively.
Described two tubular shape memory alloy springs with are connected shape memory alloy spring and connect respectively single-chip microcomputer and be subjected to this Single-chip Controlling break-make heating current.
The utility model is by the mechanism and mainly comprise the flexible rubber pipe and the clamp system of tubular shape memory alloy spring forms of moving ahead that mainly comprises the shape memory alloy spring that can alternately stretch and common spring, alternating action by move ahead mechanism and clamp system, described cable de-icing device can be anyhow or have the overhead transmission line at certain inclination angle to move ahead, and utilize the heat that distributes in the walking process to reach the effect of quick deicing.
Compare with art methods, cable de-icing device described in the utility model utilizes the principle that marmem can dilatation after energising heating, realized that this device can walk along overhead transmission line, and carry out the automatic de-icing operation while walking, the restriction of the factors such as the utility model is not conducted oneself with dignity, surrounding environment and weather, greatly reduced labor strength, and can arrive the route that manually is difficult to arrive and carry out deicing, described apparatus structure is simple, with low cost, uses safety and deicing efficiency is high, the power consumption is low.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is cutaway view of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Please in conjunction with consulting Fig. 1 and Fig. 2, diagram comprises two flexible rubber pipes 1, two tubular shape memory alloy springs 2, two supporting brackets 3, a plurality of shape memory alloy spring 5 and a plurality of common spring 4 based on the cable de-icing device of marmem, it can be divided into move ahead mechanism and clamp system two large modules, rely on the synergy of these two large modules, can realize the walking on cable.
Described two flexible rubber pipes 1 are placed on the periphery of cable, and it is for hollow tube and have flexibility.Two supporting brackets 3 are fixedly connected on respectively the end of two flexible rubber pipes 1, and namely a supporting bracket 3 connects a flexible rubber pipe 1.Described two tubular shape memory alloy springs 2 are embedded in respectively on the outer wall of two flexible rubber pipes 1, the an i.e. flexible rubber pipe 1 tubular shape memory alloy spring 2 that is nested, this tubular shape memory alloy spring 2 connects respectively single-chip microcomputer and is subjected to this Single-chip Controlling to pass into current flow heats; This two tubular shape memory alloy spring 2 alternately shrinks under current flow heats, diastole, and cable is produced periodic circumferential thrust, makes two flexible rubber pipes 1 alternately produce periodic locking and relieving with cable respectively.
Described a plurality of common spring 4 is placed on correspondingly respectively outside a plurality of shape memory alloy springs 5 and makes up, namely a common spring 4 is placed on outside the shape memory alloy spring 5, consist of a sub-assembly, one cable de-icing device can arrange a plurality of sub-assemblies, and the present embodiment is equipped with four identical sub-assemblies.The two ends of this sub-assembly are fastened on two supporting brackets 3 by bolt 6 and nut 7 respectively, and sub-assembly is between the two relative supporting brackets 3.Described a plurality of shape memory alloy spring 5 connects respectively single-chip microcomputer and is subjected to this Single-chip Controlling heating current and make-and-break time.Memory alloy spring 5 utilizes the heating effect of current rear rapid contraction of being heated, and drives package unit and shrinks; Stop shape memory alloy spring 5 heating are lost convergent force after its cooling, package unit is stretched.This process moves in circles, and shrinks, stretches so that device is continuous, cooperates the periodic locking of clamp system and relieving again, thereby realizes the walking function on cable, and simultaneously limit walking lateral dominance melts removing ice from cable with the waste heat that drives the marmem generation.
When described cable de-icing device based on marmem uses, at first manually with this deicer clamping on power transmission line, start power supply and single-chip microcomputer control program, right-hand member annular shape memory alloy spring 2 is carried out contraction under Single-chip Controlling, left end annular shape memory alloy spring 2 is not done any action under Single-chip Controlling; Four shape memory alloy springs 5 are carried out contraction under Single-chip Controlling, the device overall shrinkage, and owing to right-hand member and the cable locking of this moment deicer are fixed, and left end and cable are decontroled.Therefore installing left end moves right; Next constantly, left end annular shape memory alloy spring 2 is carried out under Single-chip Controlling and is shunk running, left end is fixed, right-hand member annular shape memory alloy spring 2 is not done any action under Single-chip Controlling, thereby under low temperature environment, restore to the original state rapidly, right-hand member is decontroled, meanwhile, four shape memory alloy springs 5 are not done any action under Single-chip Controlling, under the restoring force of common spring 4 and low temperature environment, stretch rapidly, realized whole moving to right thereby the Integral cable deicer restores to the original state.Under Single-chip Controlling, hocket and move as mentioned above, thus the implement device function of creeping to the right, and the waste heat that produces when driving marmem simultaneously is used for melting the icing on the cable.
The utility model has solved in the past can only be by the difficulty of artificial deicing, and safe and reliable, rational in infrastructure, efficient energy-saving operate.
