Embodiment
Embodiments of the present invention are introduced below in conjunction with accompanying drawing.
As Fig. 1, the oscillator automatically can removing high-tension cable ice and snow mainly comprises pressure sensitive platform 1 and oscillator arrangement 6.Oscillator utilizes oscillator bracket 18 to be fixedly mounted on high-voltage cable support 20, and oscillator bracket 18 is connected with dampening arrangement 19 with between oscillator.Oscillator is connected with high-tension cable 17.Pressure sensitive platform 1 covers the pressure of ice and snow thereon in order to induction, and oscillator device 6 is in order to be connected with high-tension cable 17.When the ice and snow pressure that pressure sensitive platform 1 senses reaches preset pressure, oscillator arrangement 6 produces concussion thus energizes high-pressure cable 17 produces concussion, removes the ice and snow on it.
Oscillator arrangement 6 comprises eccentric arbor wheel 15, in order to the motor 12 that drives eccentric arbor wheel to rotate and the oscillator outer cover 17 holding eccentric arbor wheel 15 and motor 12.Motor 12 has motor shaft 14, and eccentric arbor wheel 15 is fixed on motor shaft 14.Motor 12 has motor circuit 13 and controls the contact switch 11 of motor circuit 13.When the ice and snow pressure that pressure sensitive platform senses reaches a preset pressure, pressure sensitive platform 1 activated contacts switch 11.Motor 12 utilizes electric machine support 16 to be fixedly mounted in oscillator outer cover 17.
Pressure sensitive platform 1 can be rectangular structure, is elastically supported in above outer cover 17.Specifically, pressure sensitive platform 1 utilizes back-moving spring 4 to be elastically supported in above pressure sensitive platform 1.Back-moving spring 4 is between the bottom of pressure sensitive platform 1 and the upper wall of outer cover 17.Pressure sensitive post 5 is housed below pressure sensitive platform 1, when the ice and snow pressure that described pressure sensitive platform senses reaches described preset pressure, pressure sensitive post 5 activated contacts switch 11.
Pressure sensitive platform 1 is provided with the device 2 stoping birds to stop, and in order to prevent birds from resting on described pressure sensitive platform 1, produces misoperation.In the example of fig. 1, the device stoping birds to stop is the some bore spines 2 be arranged on pressure sensitive platform 1.Electric drive electro-heat equipment is equipped with in pressure sensitive platform 1 inside, such as heating resistance wire 3, in order to remove the ice and snow covered on pressure sensitive platform 1.
Oscillator outer cover 7 can be cuboid frame-shaped structure, and the middle part of upper wall has opening 8, and pressure sensitive post 5 can insert from opening 8, and just to contact switch 11.Like this, pressure sensitive platform 1 can move down under the pressure of ice and snow.When the pressure covering the ice and snow on pressure sensitive platform 1 equals described preset pressure, pressure sensitive post 5 moves to the position of activated contacts switch 11.The upper wall of outer cover 7 also leaves string holes 9, and the heating resistance wire 3 in Bonding pressure induction platform 1 and the connection electric wire 10 between contact switch 11 extend there through.The upper wall of oscillator outer cover 7 is connected with the lower end of back-moving spring 4.Electric machine support 16 is fixed on the bottom in oscillator outer cover 7, and motor 12 is fixed on electric machine support 16.Motor circuit 13 is connected with contact switch 11 two ends.
Oscillator arrangement 6 is provided with the through hole passed for high-tension cable 17.High-tension cable 17 is combined closely by insulated enclosure circle 21 through oscillator arrangement 6 and oscillator outer cover 7, and oscillator bracket 18 is fixed on high-voltage cable support 20, is connected between oscillator arrangement 6 with oscillator bracket 18 with dampening arrangement 19.In order to avoid producing resonance, the frequency values that setting motor 12 drives eccentric arbor wheel 15 to rotate will away from the natural frequency of vibration value of high-tension cable 17.
When snow and ice cover is on high-tension cable 17, also can cover on pressure sensitive platform 1 simultaneously.When ice and snow more long-pending more thick heavier time, back-moving spring 4 is compressed, and pressure sensitive post 5 moves down.When the pressure of ice and snow reaches a preset pressure, namely pressure sensitive post 5 will withstand contact switch 11(, activated contacts switch 11) connect motor circuit 13 and heating resistance wire 3, motor 12 will drive eccentric arbor wheel 15 to rotate by motor shaft 14.Owing to being eccentric arbor wheel, therefore vibrations can be produced, whole oscillator arrangement 6 is driven to shake, combined closely by insulated enclosure circle with oscillator outer cover 17 because high-tension cable 17 is through oscillator arrangement 6 again, therefore oscillator arrangement 6 also energizes high-pressure cable 17 shake, thus make high-tension cable 17 produce vibration to remove the ice and snow that high-tension cable overstocks.
Owing to being be connected by back-moving spring 4 between pressure sensitive platform 1 with oscillator arrangement 6, pressure sensitive platform 1 can not reflect the vibrations on oscillator arrangement 6, the ice and snow that pressure sensitive platform 1 overstocks is not removed by vibrations, therefore in pressure sensitive platform, heating resistance wire 3 has been installed, and the contact switch 11 that motor circuit 13 is connected with heating resistance wire 3 connects simultaneously, at this moment ice and snow (ice and snow set on vibration removal high-tension cable is roughly the same with the time that the ice and snow removed on pressure sensitive platform is dissolved in heating resistance wire heating) has been dissolved in heating resistance wire 3 heating, when after removing ice and snow, pressure relieve on pressure sensitive platform 1, back-moving spring 4 resets, contact switch 11 disconnects, motor circuit 13 and heating resistance wire 3 quit work simultaneously, all recover former state.Owing to being connected with damping device 19 between oscillator arrangement 6 with oscillator bracket 18, the vibrations of oscillator arrangement 6 can not have influence on oscillator bracket 18, and therefore oscillator bracket 18 can play the effect of firm support oscillator arrangement 6.Frequency values that motor 12 drives eccentric arbor wheel 15 to rotate to be set before using away from the natural frequency of vibration value of high-tension cable 17, the danger of resonance would not be produced like this.
In sum, the oscillator of a kind of automatic removal high-tension cable ice and snow of the present invention can reach the object automatically removing the ice and snow that high-tension cable overstocks, and saves time, laborsaving, economical, efficient.
