A splitter is provided between the four-split conductors for fixing the four-split conductors, including a shearing mechanism, a mounting plate 100 and a driving mechanism. The four-split conductors are distributed in a matrix, and the perpendicular bisectors of the two conductors located in the same column are the first axis, and the perpendicular bisectors of the two conductors located in the same row are the second axis. There are four shearing mechanisms, and the four shearing mechanisms correspond to the four conductors respectively, wherein two shearing mechanisms are symmetrically arranged about the first axis, and the other two shearing mechanisms are symmetrically arranged about the second axis. The mounting plate 100 is arranged on the four-split conductors, and four mounting bins 101 are provided on the mounting plate 100. Each shearing mechanism is arranged in one mounting bin 101. Each shearing mechanism includes a first clamping assembly and a second clamping assembly. The first clamping assembly is located in front of the second clamping assembly.

The rotating wheel 103 is fixedly mounted on the rotating shaft 102, and the rotating wheel 103 is coaxial with the rotating shaft 102. The rotating wheel 103 rotates on the corresponding conductor and moves relative to the conductor along the extension direction of the conductor; the second clamping assembly includes two supporting parts, the two supporting parts are arranged oppositely in the installation chamber 101, and each supporting part is located on the inner side of the four-split conductor, and each supporting part includes a fixed shaft 104 and a rotating block 105, and the fixed shaft 104 is arranged On the mounting plate 100, and its axis extends along the first direction, the rotating block 105 is rotatably set at one end of the fixed shaft 104, the second axis extends in the second direction, the rotating axis of the rotating block 105 extends in the second direction, and the rotating block 105 is provided with resistance in its rotation direction; the rotating blocks 105 of the two supporting parts are slidably connected with the corresponding wires, the vertical distance between the rotating shaft 102 and the first axis is smaller than the vertical distance between the rotating block 105 and the first axis, and the driving mechanism is set on the mounting plate 100, and is used to drive the mounting plate 100 to move along the length direction of the four-split wire.

[0024] The conductor is placed in the device. Through the coordinated setting of the positions of the rotating shaft 102 and the fixed shaft 104, the extension direction of the conductor between the rotating shaft 102 and the rotating block 105 is inconsistent with the extension directions of the uncleaned part and the cleaned part of the conductor. The conductor between the rotating shaft 102 and the rotating block 105 is misaligned. The rotating shaft 102 and the rotating block 105 apply a shearing force to the conductor therebetween to destroy the ice layer on the surface of the conductor and break it into pieces. The shearing forces generated by the four shearing mechanisms on the conductor are in opposite directions, so that the conductor will not be deviated when subjected to the shearing force, thereby reducing the effect of removing the ice layer.

[0025] In the present embodiment, the first clamping assembly further includes a limit frame and a limit plate 106, the limit frame is slidably arranged on the mounting plate 100 along the second direction, the rotating shaft 102 passes through the limit frame and is slidably connected to the limit frame, the limit plate 106 is rotatably arranged on the limit frame, and the rotation axis of the limit plate 106 extends along the second direction, one of the wires is located between the limit plate 106 and the rotating shaft 102, and the wire passes through the limit frame; the limit plate 106 is slidably connected to the wire, the limit frame includes a transverse plate 108 and two side plates 107, one end of the two side plates 107 is respectively connected to the two opposite side surfaces of the transverse plate 108, and the two side plates 107 are arranged on the transverse plate 108 along the first direction, and the mounting plate 100 is provided with two first slide grooves 109, the first slide grooves 109 are relatively arranged in the mounting bin 101, the side plates 107 are L-shaped, and the ends of the two side plates 107 away from the transverse plate 108 slide along the second direction respectively. The first spring 123 is provided in each of the first slide grooves 109, and the two ends of the first spring 123 in each of the first slide grooves 109 are respectively connected to the mounting plate 100 and the corresponding side plate 107 away from the rotating shaft 102. A first through hole 110 is provided on each of the two side plates 107. The rotating shaft 102 passes through the side plates 107 and is slidably arranged in the first through hole 110. The rotating wheel 103 is arranged between the two side plates 107. The limiting plate 106 is rotatably arranged on the side plate 107, and the limiting plate 106 is located between the two side plates 107, and the limiting plate 106 is located at a position where the side plate 107 is away from the cross plate 108. When the distance between the wire and the rotating shaft 102 increases due to ice, under the support of the wire, the distance between the rotating shaft 102 and the limiting plate 106 increases, and the wire is still between the rotating shaft 102, the limiting plate 106 and the two side plates 107.

[0026] In this embodiment, a first torsion spring is provided between the limit plate 106 and the limit frame, and the torsion of the first torsion spring is greater than the sliding friction between the wire and the limit plate 106. By providing the first torsion spring, the wire can more conveniently enter between the limit plate 106 and the rotating shaft 102, thereby making the wire contact with the rotating wheel 103, making it difficult for the wire to detach from the rotating wheel 103.

[0027] In this embodiment, the side edges of the limit plate 106 close to the wire are provided with rounded corners. When the wire approaches the limit plate 106, it can slide and contact with the limit plate 106 through the rounded corners of the limit plate 106, thereby reducing the sliding resistance between the limit plate 106 and the wire and extending the service life of the first torsion spring.

[0028] In this embodiment, the second clamping assembly further includes a positioning plate 111 and two clamping plates 112. Each mounting chamber 101 is provided with a second slide groove 113 which is arranged opposite to each other. Both ends of the positioning plate 111 are slidably arranged in the corresponding second slide groove 113 along the second direction. The positioning plate 111 is located on the outside of the wire corresponding to the rotating block 105. The wire is located between the positioning plate 111 and the rotating block 105. A second spring is arranged in each second slide groove 113. One end of each second spring is connected to a side of the positioning plate 111 away from the fixed axis 104. The other end of the second spring is connected to the mounting plate 10 0 connection, two clamping plates 112 are arranged on a surface of the positioning plate 111 close to the wire, the two clamping plates 112 are arranged along a first direction on the positioning plate 111, and a second through hole 114 is opened on each clamping plate 112, one of the fixed shafts 104 passes through a clamping plate 112 and is slidably arranged on the clamping plate 112 along two directions, and the rotating block 105 on the fixed shaft 104 is located between the two clamping plates 112, when the wire slides on the rotating block 105, the positioning plate 111 abuts against the wire under the action of the second spring, and the positioning plate 111 can scrape off the broken ice layer of the wire.

[0029] In this embodiment, a second torsion spring is provided between each rotating block 105 and the corresponding fixed shaft 104, the torsion of the second torsion spring is greater than the thrust applied by the corresponding wire to the rotating block 105, and the side edges of the rotating block 105 close to the wire are provided with chamfered corners. The axis of the fixed shaft 104 is farther away from the first axis than the axis of the rotating shaft 102, so the wire passing through the rotating wheel 103 will exert a force on the rotating block 105 when passing through the rotating block 105, and this force makes the rotating block 105 tend to rotate relative to its rotating axis. The second torsion spring is provided to reduce the force applied by the wire on the rotating block 105, and the design of the chamfered corners of the rotating block 105 can further reduce the force applied by the wire on the rotating block 105.

[0030] In this embodiment, two driving mechanisms are provided, and the two driving mechanisms are symmetrically arranged relative to the second axis. Each driving mechanism includes a motor 115, a transmission shaft 116, a first gear 117, a second gear 118, two third gears 119 and two fourth gears 120. The motor 115 is fixedly mounted on the mounting plate 100, the transmission shaft 116 is rotatably arranged on the mounting plate 100, and the axis of the transmission shaft 116 extends along the second direction. The first gear 117 is mounted on the output end of the motor 115, and the second gear 118 is fixedly mounted on the transmission shaft 116, and the second gear 118 is coaxial with the transmission shaft 116. The first gear 117 and the second gear 118 are coaxial. The first gear 117 and the second gear 118 are meshed with each other, and two third gears 119 are respectively installed at both ends of the transmission shaft 116, and the two third gears 119 are coaxial with the transmission shaft 116. One end of the rotating shaft 102 passes through the mounting plate 100. Two fourth gears 120 are respectively installed on the two rotating shafts 102 on one side of the second axis. Each third gear 119 is meshed with a fourth gear 120. The motor 115 drives the transmission shaft 116 to rotate through the first gear 117 and the second gear 118. The transmission shaft 116 drives the two fourth gears 120 to rotate in the opposite direction through the two third gears 119. The two fourth gears 120 drive the rotating wheel 103 to move on the wire through the rotating shaft 102.

[0031] In this embodiment, the circumferential surface of the rotating wheel 103 is an arc surface, and the diameters of the two ends of the rotating wheel 103 are larger than the diameter of the middle position. A plurality of protrusions are provided on the circumferential surface of the rotating shaft 102, each protrusion is conical, and the large end of each protrusion is fixedly connected to the circumferential surface of the rotating shaft 102. The setting of the arc surface of the rotating wheel 103 can increase the contact area between the rotating wheel 103 and the wire, and increase the friction between the rotating wheel 103 and the wire. The setting of the protrusions makes the rotating wheel 103 have a smaller effective area for the wire with ice on the surface, the protrusions penetrate deeper into the ice layer, and have a greater grip on the wire. The rotation of the rotating wheel 103 can better drive the deicing device to move forward along the wire.

[0032] In this embodiment, the splitter includes a hanging ear 121 and a rectangular frame 122. There are four hanging ears 121, one end of each hanging ear 121 is connected to a corresponding wire, and the end of each hanging ear 121 away from the wire is slidably connected to the rectangular frame 122 along the second direction. The rectangular frame 122 is located between the four split wires, and each hanging ear 121 extends along the second direction. The hanging ear 121 does not contact the mounting plate 100. When passing through the mounting plate 100, the hanging ear 121 will overcome the torsion of the first torsion spring and pass over the limiting plate 106 after abutting against the limiting plate 106. After the hanging ear 121 abuts against the rotating block 105, it will overcome the torsion of the second torsion spring and push the second torsion spring to rotate. The width of the position where the hanging ear 121 contacts the rotating block 105 is smaller than the diameter of the wire. After the two rotating blocks 105 rotate, the wire will not detach from the rotating block 105.

[0033] In this embodiment, a vibration mechanism is provided on the mounting plate 100 (the vibration mechanism is a conventional vibration cleaning mechanism well known to those skilled in the art, so it is not described in detail and is not shown in the figure). The vibration mechanism is located at the rear of the mounting plate 100 and is used to clean the broken ice layer on the four-split conductor.

[0034] The working principle and working method of a conductor deicing device for a high-voltage power transmission and transformation project provided in this embodiment are as follows: First, place the four-split conductors between the mounting plates 100 so that the rotating shaft 102 is located in front of the fixed shaft 104. Taking the shearing mechanism in an mounting bin 101 as an example, rotate the limit plate 106 to make the corresponding conductor contact the rotating wheel 103, then loosen the limit plate 106. The limit plate 106 rotates in the opposite direction and resets under the action of the first torsion spring, blocking the conductor between the limit plate 106 and the cross plate 108. Then rotate the rotating block 105. The part of the conductor located behind the rotating shaft 102 is between the rotating block 105 and the positioning plate 111. Loosen the rotating block 105. The rotating block 105 is reset under the action of the second torsion spring, and the conductor is slidably connected to the rotating block 105. The corresponding conductors of the remaining three mounting bins 101 are installed in the shearing mechanism in the same way.

[0035] Then, the two motors 115 are started. Each motor 115 drives the corresponding transmission shaft 116 to rotate through the meshing of the first gear 117 and the second gear 118. The transmission shaft 116 drives the corresponding rotating shaft 102 to rotate through the third gear 119 and the fourth gear 120. The rotating shaft 102 drives the rotating wheel 103 to rotate. The rotating wheel 103 rotates on the wire and drives the mounting plate 100 to move. When the rotating wheel 103 passes through the wire with ice, the diameter of the wire becomes larger, and the wire will push the limiting plate 106 to move away from the rotating wheel 103. The limiting plate 106 drives the limiting frame to move on the mounting plate 100, and the limiting frame compresses the first spring 123. The wire passing through the rotating wheel 103 rotates around the rotating wheel 103 for a certain angle and then approaches the rotating block 105. When the wire rotates, the ice layer on its surface is destroyed. When passing through the rotating block 105, the wire rotates again for a certain angle, and the ice layer on the wire is broken again.

[0036] When the conductor passes through the rotating block 105 , the positioning plate 111 is slidably connected with the conductor under the action of the second spring, and a part of the broken ice layer on the conductor can be removed by scraping of the positioning plate 111 .

[0037] When the device passes through the splitter on the four-split conductor, the hanging ear 121 will first contact the limit plate 106, and the hanging ear 121 will push the limit plate 106 to rotate, thereby passing over the limit plate 106. When the limit plate 106 contacts the hanging ear 121, the conductor is still in abutment with the limit plate 106. After the hanging ear 121 passes through the rotating wheel 103, since the distance between the two conductors located on the same side of the second axis in the second direction increases, the conductor pulls the hanging ear 121 to slide relative to the rectangular frame 122 along the second direction. When the hanging ear 121 passes through the rotating block 105, it will push the rotating block 105 to rotate. After the hanging ear 121 is separated from the rotating block 105, the rotating block 105 is reset under the action of the second torsion spring, and the conductor will not be separated from between the rotating block 105 and the positioning plate 111 during this period.

[0038] The ice layer that is broken on the surface of the conductor processed by the shearing mechanism but still adheres to the conductor will fall off the conductor after being vibrated by the vibrating mechanism.

[0039] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
