[0002] In extra-high voltage transmission lines, in order to suppress corona discharge and reduce line reactance, bundled conductors are generally used for erection, and among them, four-bundled conductors are the most commonly used.

Transmission line icing can cause problems such as conductor galloping, tower inclination, collapse, wire breakage, and insulator flashover, seriously affecting the normal operation of power facilities.
[0004] Existing line snow-removing devices often use methods such as scraping with a scraper and generating tremors to remove snow, but it is difficult to remove the ice layer formed due to temperature changes; existing technologies often use circumferential pressure application to fracture the ice layer, but the cylindrical ice layer has strong compressive performance and is very smooth, and the conductor with the ice layer is easily squeezed away after circumferential pressure application, making it difficult to fracture.

[0030] Such as Figures 1 to 7As shown in the figure, an ice removing device for a high-voltage power transmission and transformation project provided by an embodiment of the present invention de-ices four bundled conductors from the back to the front along the extension direction of the four bundled conductors. A spacer is provided between the four bundled conductors for fixing the four bundled conductors. The device includes a shearing mechanism, a mounting plate 100, and a driving mechanism. The four bundled conductors are distributed in a matrix. The perpendicular bisector of two conductors in the same column is the first axis, and the perpendicular bisector of two conductors in the same row is the second axis. There are four shearing mechanisms, and the four shearing mechanisms respectively correspond to the four conductors. Two of the 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 bundled conductors. Four mounting bins 101 are provided on the mounting plate 100, and each shearing mechanism is arranged in a 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 first clamping assembly includes a rotating shaft 102 and a rotating wheel 103. The rotating shaft 102 is rotatably arranged on the mounting plate 100. The rotating shaft 102 is located outside the four bundled conductors. The extension direction of the first axis is the first direction, and the axis of the rotating shaft 102 extends along the first direction. The rotating wheel 103 is fixedly installed on the rotating shaft 102 and is coaxial with the rotating shaft 102. The rotating wheel 103 rotates on the corresponding conductor and moves along the extension direction of the conductor relative to the conductor. The second clamping assembly includes two supporting parts. The two supporting parts are arranged oppositely in the mounting bin 101, and each supporting part is located inside the four bundled conductors. Each supporting part includes a fixed shaft 104 and a rotating block 105. 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 arranged at one end of the fixed shaft 104. The extension direction of the second axis is the second direction, and the rotation axis of the rotating block 105 extends in the second direction. The rotating block 105 has a resistance in its rotation direction. The rotating blocks 105 of the two supporting parts are slidably connected to the corresponding conductors. The perpendicular distance between the rotating shaft 102 and the first axis is less than the perpendicular distance between the rotating block 105 and the first axis. The driving mechanism is arranged on the mounting plate 100 and is used to drive the mounting plate 100 to move along the length direction of the four bundled conductors.
[0031] When the conductor is placed in the device, through the cooperative 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 between them, breaking the ice layer on the surface of the conductor and making it crack. The shearing forces generated by the four shearing mechanisms on the conductor are in opposite directions, so that the conductor will not be offset when subjected to the shearing force and the ice layer removal effect will not be reduced.
[0032] In this embodiment, the first clamping assembly further includes a limiting frame and a limiting plate 106. The limiting frame is slidably arranged on the mounting plate 100 along the second direction. The rotating shaft 102 penetrates through the limiting frame and is slidably connected to the limiting frame. The limiting plate 106 is rotatably arranged on the limiting frame, and the rotation axis of the limiting plate 106 extends along the second direction. One of the wires is located between the limiting plate 106 and the rotating shaft 102, and this wire penetrates through the limiting frame. The limiting plate 106 is slidably connected to the wire. The limiting frame includes a cross plate 108 and two side plates 107. One ends of the two side plates 107 are respectively connected to two opposite side surfaces of the cross plate 108, and the two side plates 107 are arranged along the first direction on the cross plate 108. Two first sliding grooves 109 are formed in the mounting plate 100. The first sliding grooves 109 are oppositely arranged in the mounting cavity 101. The side plates 107 are L-shaped. One ends of the two side plates 107 far from the cross plate 108 are respectively slidably arranged in the corresponding first sliding grooves 109. A first spring 123 is arranged in each first sliding groove 109. Two ends of the first spring 123 in each first sliding groove 109 are respectively connected to the mounting plate 100 and one surface of the corresponding side plate 107 far from the rotating shaft 102. First through holes 110 are formed in both side plates 107. The rotating shaft 102 penetrates through the side plates 107 and is slidably arranged in the first through holes 110. The rotating wheel 103 is arranged between the two side plates 107. The limiting plate 106 is rotatably arranged on the side plates 107, and the limiting plate 106 is located between the two side plates 107 and at a position of the side plates 107 far from the cross plate 108. When the distance between the wire and the rotating shaft 102 increases due to icing, under the support of the wire, the distance between the rotating shaft 102 and the limiting plate 106 increases, and the wire still remains between the rotating shaft 102, the limiting plate 106 and the two side plates 107.
[0033] In this embodiment, a first torsion spring is arranged between the limiting plate 106 and the limiting frame. The torsion of the first torsion spring is greater than the sliding friction force between the wire and the limiting plate 106. By arranging the first torsion spring, the wire can more conveniently enter between the limiting plate 106 and the rotating shaft 102, so that the wire contacts the rotating wheel 103, and the wire is not easily separated from the rotating wheel 103.
[0034] In this embodiment, the side edge of the limiting plate 106 close to the wire is provided with a chamfer. When the wire approaches the limiting plate 106, the wire can be in sliding contact with the limiting plate 106 through the chamfer of the limiting plate 106, reducing the sliding resistance between the limiting plate 106 and the wire and prolonging the service life of the first torsion spring.
[0035] In this embodiment, the second clamping assembly further includes a positioning plate 111 and two clamping plates 112. A second chute 113 is provided in each mounting bin 101 and is arranged oppositely. The two ends of the positioning plate 111 are slidably arranged in the corresponding second chute 113 along the second direction. The positioning plate 111 is located outside the wire corresponding to the rotating block 105, and the wire is located between the positioning plate 111 and the rotating block 105. A second spring is provided in each second chute 113. One end of each second spring is connected to the surface of the positioning plate 111 away from the fixed shaft 104, and the other end of the second spring is connected to the mounting plate 100. The two clamping plates 112 are arranged on the surface of the positioning plate 111 close to the wire. The two clamping plates 112 are arranged along the first direction on the positioning plate 111. A second through hole 114 is provided in each clamping plate 112. One of the fixed shafts 104 penetrates through one clamping plate 112 and is slidably arranged on the clamping plate 112 along the second direction, 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 the broken ice layer on the wire.
[0036] In this embodiment, a second torsion spring is provided between each rotating block 105 and the corresponding fixed shaft 104. The torsion force of the second torsion spring is greater than the thrust exerted by the corresponding wire on the rotating block 105. A chamfer is provided on the side edge of the rotating block 105 close to the wire. The axis of the fixed shaft 104 is farther from the axis of the first axis than the axis of the rotating shaft 102. Therefore, when the wire passing through the rotating wheel 103 passes through the rotating block 105, a force will be exerted on the rotating block 105, and this force causes the rotating block 105 to have a tendency to rotate relative to its rotation axis. By providing the second torsion spring, the force exerted by the wire on the rotating block 105 can be reduced. The design of the chamfer of the rotating block 105 can further reduce the force exerted by the wire on the rotating block 105.
[0037] In this embodiment, there are two driving mechanisms, and the two driving mechanisms are symmetrically arranged with respect 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 installed 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 installed at the output end of the motor 115. The second gear 118 is fixedly installed on the transmission shaft 116 and is coaxial with the transmission shaft 116. The first gear 117 meshes with the second gear 118. The two third gears 119 are respectively installed at both ends of the transmission shaft 116 and are coaxial with the transmission shaft 116. One end of the rotating shaft 102 penetrates through the mounting plate 100. The two fourth gears 120 are respectively installed on the two rotating shafts 102 on one side of the second axis. Each third gear 119 meshes with one 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 opposite directions through the two third gears 119. The two fourth gears 120 drive the runner 103 to move on the wire through the rotating shaft 102.
[0038] In this embodiment, the peripheral surface of the runner 103 is an arc surface, and the diameters of both ends of the runner 103 are larger than the diameter of the middle position thereof. A plurality of convex blocks are provided on the peripheral surface of the rotating shaft 102. Each convex block is conical, and the large end of each convex block is fixedly connected to the peripheral surface of the rotating shaft 102. The arc surface setting of the runner 103 can increase the contact area between the runner 103 and the wire, and increase the friction between the runner 103 and the wire. By providing the convex blocks, the acting area of the runner 103 on the wire with ice on the surface is smaller, the depth of the convex blocks piercing into the ice layer is greater, the grasping force on the wire is greater, and the rotation of the runner 103 can better drive the de-icing device to move forward along the wire.
[0039] In this embodiment, the splitter includes hanging ears 121 and a rectangular frame 122. There are four hanging ears 121. One end of each hanging ear 121 is correspondingly connected to a wire. 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. Each hanging ear 121 extends along the second direction. The hanging ears 121 do not contact the mounting plate 100. When passing through the mounting plate 100, the hanging ears 121 will overcome the torsion of the first torsion spring and cross over the limiting plate 106 after abutting against the limiting plate 106. After the hanging ears 121 abut against the rotating blocks 105, they 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 ears 121 contact the rotating blocks 105 is smaller than the diameter of the wire. After the two rotating blocks 105 rotate, the wire will not be separated from the rotating blocks 105.
[0040] 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 will not be described in detail and is not shown in the figure). The vibration mechanism is located behind the mounting plate 100 and is used to clean the fragmented ice on the four-split conductor.
[0041] The working principle and method of a conductor de-icing device for high-voltage power transmission and transformation projects provided in this embodiment are as follows:
[0042] First, place the four-split conductor between the mounting plates 100 so that the rotating shaft 102 is in front of the fixed shaft 104. Taking the shearing mechanism in one mounting bin 101 as an example, rotate the limiting plate 106 to make the corresponding conductor contact the rotating wheel 103. Then release the limiting plate 106, and the limiting plate 106 rotates reversely and resets under the action of the first torsion spring, blocking the conductor between the limiting plate 106 and the cross plate 108. Then rotate the rotating block 105. The part of the conductor behind the rotating shaft 102 is between the rotating block 105 and the positioning plate 111. Release the rotating block 105, and the rotating block 105 resets under the action of the second torsion spring. The conductor is slidably connected to the rotating block 105. The conductors corresponding to the other three mounting bins 101 are installed in the shearing mechanism in the same way.
[0043] Then start the two motors 115. 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 rotation of the rotating wheel 103 drives the mounting plate 100 to move on the conductor. When the rotating wheel 103 passes over the conductor with ice, the diameter of the conductor becomes larger, and the conductor 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; after the conductor passing over the rotating wheel 103 rotates around the rotating wheel 103 by a certain angle and approaches the rotating block 105, when the conductor rotates, the ice layer on its surface is damaged. When passing over the rotating block 105, the conductor rotates by a certain angle again, and the ice layer on the conductor is fragmented again.
[0044] When the conductor passes over the rotating block 105, the positioning plate 111 is slidably connected to the conductor under the action of the second spring. After being scraped by the positioning plate 111, part of the fragmented ice layer on the conductor can be removed.
[0045] When the device passes through the splitter on the four-split conductor, the lug 121 will first contact the limiting plate 106. The lug 121 pushes the limiting plate 106 to rotate, so as to cross the limiting plate 106. When the limiting plate 106 contacts the lug 121, the conductor is still in contact with the limiting plate 106. After the lug 121 passes through the runner 103, since the distance between the two conductors on the same side of the second axis increases in the second direction, the conductor pulls the lug 121 to slide relative to the rectangular frame 122 in the second direction. When the lug 121 passes through the rotating block 105, it will push the rotating block 105 to rotate. After the lug 121 is separated from the rotating block 105, the rotating block 105 resets under the action of the second torsion spring. During this period, the conductor will not fall out from between the rotating block 105 and the positioning plate 111.
[0046] The ice layer that has broken but still adheres to the conductor on the surface of the conductor processed by the shearing mechanism will fall off from the conductor after being vibrated by the vibrating mechanism.
[0047] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, 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, it should be considered as the scope described in this specification.
[0048] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
