A driving roller 4 is arranged in the lower box body 2 through a driving motor 11 and a transmission belt; when the driving motor 11 works, the driving roller 4 can be driven by the driving belt to synchronously rotate.
An end socket at one end of the upper box body 1 is provided with an oscillation generator A6; an end socket at one end of the lower box body 2 is provided with an oscillation generator B7; the oscillation generator A6 and the oscillation generator B7 are oppositely arranged (refer to the attached figure 2 in the specification).
The oscillation generator a6 and the oscillation generator B7 are each constituted by a striking rod 14, an oscillation motor 15, a rotating disk 16, a pressing wheel 17, and a mounting plate 18 (see fig. 3 in the specification).
The return spring 21 is a support spring, and under the action of the elastic force of the return spring 21, the extrusion cambered surface 22 of the extrusion plate 20 can always keep intermittent rolling connection with each extrusion wheel 17, so that when one extrusion wheel 17 rotates to be in contact with the extrusion cambered surface 22, the extrusion wheel 17 can push the impact rod 14 to act through the extrusion plate 20; when the extrusion wheel 17 is separated from the extrusion cambered surface 22, the extrusion plate 20 can drive the impact rod 14 to reset under the action of the elastic force of the return spring 21; therefore, when the extrusion wheels 17 are intermittently connected with the extrusion plates 20, the impact rod 14 can be pushed to impact the high-voltage wire continuously, and the aim of vibrating the high-voltage wire to remove ice is achieved.
A mounting plate 18 at one end of the extrusion plate 20 is provided with a rotating disc 16 (see the description and the attached figure 3) through an oscillating motor 15; the oscillating motor 15 can drive the rotating disc 16 to rotate synchronously when working.
A plurality of extrusion wheels 17 are uniformly arranged on the circumferential surface of the rotating disk 16 through a bracket; when the rotating disk 16 rotates, the electric extrusion wheels 17 can synchronously rotate; during the rotation of each extrusion wheel 17, the purpose of pushing the striking rod 14 to act and strike the high-voltage wire through the extrusion plate 20 can be achieved.
The extrusion wheels 17 in the oscillation generator A6 and the oscillation generator B7 are in a staggered state, so that the oscillation generator A6 and the oscillation generator B7 can impact a high-voltage wire in a staggered mode to oscillate when the device works; thereby avoiding the problem of "interference" when oscillation generator a6 and oscillation generator B7 hit the high voltage line at the same time.
A salt storage chamber 23 (see the attached figure 4 in the specification) is arranged in the upper box body 1; the lower end of the salt storage chamber 23 is provided with a salt outlet 24; a salt guide slide carriage 25 is movably arranged in the salt outlet 24 through a rotating pin; the upper end of the salt guide slide carriage 25 is fixedly provided with a sealing turnover plate 26; the sealing turnover plate 26 is intermittently and hermetically connected with the salt outlet 24; the lower end of the salt guiding slide carriage 25 extends to the lower part of the upper box body 1; a slide carriage supporting spring 27 is arranged between the salt guiding slide carriage 25 and the salt storage chamber 23 (refer to the attached figure 4 in the specification).
Under the action of the elastic force of the slide carriage supporting spring 27, the salt guide slide carriage 25 always has the tendency of downward rotation, and the sealing turnover plate 26 is in sealing connection with the salt outlet 24; thus, the problem of leakage of the deicing salt in the salt storage chamber 23 in a non-working state can be avoided. When the salt-guiding slide carriage 25 is forced to overcome the elastic force of the slide carriage supporting spring 27 and rotates upwards, the salt-guiding slide carriage 25 can drive the sealing turning plate 26 to move upwards synchronously, so that the salt outlet 24 is opened, and the deicing salt in the salt storage chamber 23 can slide downwards smoothly along the salt-guiding slide carriage 25.
An arc-shaped joint opening (not shown in the attached drawing of the specification) is arranged at the outlet of the lower end of the salt guiding slide carriage 25. The radian of the arc-shaped fitting opening is consistent with that of the circumferential surface of the high-voltage wire; so set up the purpose of arc laminating mouth and lie in: so that during operation, the outlet of the salt guiding slide carriage 25 can be in sliding connection with the surface of the high-voltage wire through the arc-shaped joint, and accordingly deicing salt can smoothly slide to the surface of the high-voltage wire along the salt guiding slide carriage 25 and cover the surface of the high-voltage wire during operation.
Each power motor in the oscillating type high-voltage line deicing machine can be designed as an alternating current motor, and the alternating current is provided for the power motors when the oscillating type high-voltage line deicing machine works; the power motors can be designed as direct current motors, and when the power box works, direct current is supplied from the outside to provide power for the power motors, and a storage battery can be additionally arranged in the lower box body 2 to provide direct current for the power motors.
When the oscillating type high-voltage wire deicing machine works, firstly, the starting end of a high-voltage wire to be deiced needs to be cleaned manually, and then the deicing machine is placed on the high-voltage wire from the side (see the attached figure 1 of the specification); at the moment, the guide roller 5 is in abutting connection with the high-voltage wire; meanwhile, the salt-guiding slide carriage 25 is extruded by the high-voltage wire, so that the salt-guiding slide carriage overcomes the elasticity of the slide carriage supporting spring 27 and then drives the sealing turning plate 26 to synchronously move upwards, and further the salt outlet 24 is opened, so that the deicing salt in the salt storage chamber 23 can smoothly slide downwards to the upper surface of the high-voltage wire along the salt-guiding slide carriage 25.
After the ice removing machine is placed, starting an adjusting motor 10 to drive an upper box body 1 to slide upwards along a guide slide rod 8 through an adjusting screw rod 3; when the lower box body 2 is buckled with the upper box body 1, the motor 10 is adjusted to stop acting; at the moment, the driving roller 4 is in abutting connection with the high-voltage wire; and then starting the oscillating motor 15 in the oscillation generator A6 and the oscillation generator B7 to enable the oscillation generator A6 and the oscillation generator B7 to impact the high-voltage line in a staggered manner to enable the high-voltage line to oscillate, so that the aim of deicing is fulfilled.
In this process, the driving motor 11 is started to drive the driving roller 4 to rotate synchronously through the transmission belt. In the rotation process of the driving roller 4, the whole deicing machine can be pushed to move forwards under the coordination of the guide roller 5; in the process of advancing the deicing machine, the high-voltage wire can be impacted in a staggered manner by the oscillation generator A6 and the oscillation generator B7 to oscillate, so that the aim of continuous deicing is fulfilled. Furthermore, the salt-guiding chute 25 can smoothly guide the deicing salt to the high-voltage line so as to cover the upper surface of the high-voltage line in the continuous deicing process.
After the deicing salt is covered on the upper surface of the high-voltage wire, because the surface of the high-voltage wire is rough, a lot of deicing salt tends to stay on the surface of the high-voltage wire; therefore, the principle that deicing salt can reduce the icing temperature can be utilized, the icing of the high-voltage wire is delayed, and the purpose of reducing the deicing frequency of the high-voltage wire is further achieved.
At present, domestic high-voltage wires are of steel-cored aluminum stranded wire structures, a layer of compact oxidation film can be formed on the surface of the aluminum stranded wire outside the high-voltage wires, and the corrosion problem caused by reaction of deicing salt and the high-voltage wires can be avoided.
The oscillating type high-voltage line deicing machine is compact in structure and ingenious in design; the high-voltage wire can be oscillated in a mode of high-frequency impact on the high-voltage wire by the oscillation generator A and the oscillation generator B, so that the aim of oscillation separation and deicing is fulfilled; therefore, the problem of incomplete deicing of the existing deicing machine is solved; in addition, when the deicing machine works, deicing salt can be covered on the surface of the high-voltage wire, so that the aim of delaying the icing of the high-voltage wire is fulfilled by using the principle that the deicing salt can reduce the icing temperature, and the deicing frequency of the high-voltage wire is reduced, thereby meeting the use requirement of the high-voltage wire for deicing.
