Description

Technical Field

[0001] The present invention relates to the technical field of deicing devices, and in particular to a wire deicing device based on thermal ice melting. Background Art

[0002] Since the 1950s, there have been more than 5,000 icing accidents on my country's transmission lines, and icing on transmission lines has become one of the major natural disasters threatening the safe and stable operation of power grids. In order to effectively avoid the impact of rain and snow disasters on transmission lines, effective deicing of power systems is still a key issue in current research.

[0003] There are various ice melting and deicing methods at home and abroad, which are mainly divided into thermal deicing and mechanical deicing. In the mechanical deicing process, the existing technology uses cutting to remove ice, but this method can only de-ice one side of the cable in order to facilitate the disassembly of the deicing device. In practice, ice ridges will be distributed around the cable. This situation causes the existing deicing method to be unable to completely de-ice, and multiple deicing is required, which is inefficient. Summary of the invention

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example

[0034] The present invention provides a wire deicing device based on thermal ice melting, see Figure 1-Figure 10, including a support frame 100, a cutting mechanism 200 is arranged at one end of the support frame 100, and a walking component 300 is arranged at the other end; when working, it is hoisted on the electric wire through the walking component 300, and the whole deicing device is controlled to move along the length direction of the electric wire. During the moving process, the ice edges on the outside of the electric wire are broken and removed by the cutting mechanism 200.

[0035] Specifically, the cutting mechanism 200 includes a semicircular mounting half ring 210 that is embracing the two sides of the electric wire. A distance adjustment component 220 is provided on the support frame 100 to drive each mounting half ring 210 to move toward or away from the electric wire. The same end surface of the two mounting half rings 210 is provided with a rotating track 211 of the same diameter, and a rotating deicing component 230 is rotatably provided on the rotating track 211. The two mounting half rings 210 are controlled to move toward each other in the vertical direction by the distance adjustment component 220, so that they can be synchronously approached or synchronously away from the electric wire. When deicing is performed, the two mounting half rings 210 are controlled to embracing the electric wire. After embracing, deicing is performed during the rotation process by the rotating deicing component 230. When disassembly is required, the two mounting half rings 210 are controlled to move toward the side away from the electric wire so that the two mounting half rings 210 are separated. After separation, disassembly can be performed.

[0036] The rotating track 211 is semicircular, and both ends of the rotating track 211 penetrate the end surface of the mounting half ring 210. When the two mounting half rings 210 are butt-jointed, the two rotating tracks 211 enclose a circle, and the cross section of the rotating track 211 is T-shaped.

[0037] The rotating deicing assembly 230 includes a rotating semi-circular half ring 231, and two groups of rotating semi-rings 231 are provided. A T-shaped rail 232 with a T-shaped cross section is integrally formed on one side of the rotating semi-ring 231 close to the rotating track 211. The T-shaped rail 232 is embedded in the inner side of the rotating track 211 and can slide along the rotating track 211. Preferably, circular holes are provided on the upper and lower sides of the T-shaped rail 232, and balls are provided in the circular holes. The balls are connected to the inner wall of the rotating track 211 by rolling. By providing the balls, the friction between the inner wall of the rotating track 211 and the T-shaped rail 232 can be further reduced, thereby improving the deicing power of the rotating deicing assembly 230.

[0038] A plurality of cutting blades 233 are arranged at equal angles at one end of the rotating semi-ring 231 away from the rotating track 211 ; a driving assembly 240 is arranged between the rotating semi-ring 231 and the mounting semi-ring 210 to drive the rotating semi-ring 231 to rotate.

[0039] The cutting knife 233 is L-shaped, including a mounting portion 2331 and a cutting portion 2332 which are perpendicular to each other. A plurality of adjustment holes 2311 are provided at equal angles in the radial direction at one end of the rotating semi-ring 231 away from the rotating track 211. A positioning hole 2312 is provided in the axial direction at one end face of the rotating semi-ring 231 away from the rotating track 211. The positioning hole 2312 is connected to the adjustment hole 2311, and a positioning screw 2313 is connected to the inner thread of the positioning hole 2312. The mounting portion 2331 is inserted into the adjustment hole 2311 and is fixed by the positioning screw 2313. With this arrangement, when deicing wires of different diameters, the cutting diameter of the cutting knife 233 can be adjusted, that is, damage to the wires can be avoided, and the deicing effect can be improved at the same time.

[0040] The driving assembly 240 includes a gear plate 241 fixed on each rotating half ring 231. The gear plate 241 is semicircular. When the two rotating half rings 231 are embraced, the two gear plates 241 enclose a circle and then combine to form a complete ring gear.

[0041] A first drive motor 242 is fixedly installed on the outside of one of the installation semi-rings 210, and a first driving gear 243 is connected to the output shaft of the first drive motor 242, and the first driving gear 243 is meshed with the gear plate 241. When working, the first drive motor 242 works to drive the first driving gear 243 to rotate, thereby controlling the gear plate 241 to rotate. The two installation semi-rings 210 are controlled to rotate. Specifically, the first drive motor 242 is a variable frequency motor, and an encoder is provided on one side of the first drive motor 242. The encoder collects the number of rotations of the first drive motor 242. When the transmission ratio of the first driving gear 243 and the gear plate 241 is 1:1, when it stops, the first drive motor 242 is controlled to rotate aN circles, where a is an integer. That is, the two rotating semi-rings 231 are controlled to return to the initial position, thereby controlling the first installation semi-ring 210a and the second installation semi-ring 210b to separate.

[0042] The mounting half ring 210 includes a first mounting half ring 210a and a second mounting half ring 210b. The first mounting half ring 210a is provided with a locking assembly 250. When the first mounting half ring 210a and the second mounting half ring 210b are buckled together, the locking assembly 250 clamps and fixes the second mounting half ring 210b. The locking assembly 250 can further ensure the stability of the first mounting half ring 210a and the second mounting half ring 210b when buckled.

[0043] A locking hole 212 is formed at one end of the second mounting half ring 210b away from the rotating track 211. The locking hole 212 is arc-shaped, and one end of the locking hole 212 passes through the side surface of the second mounting half ring 210b close to the first mounting half ring 210a to form a first locking opening.

[0044] An arc-shaped operating hole 213 is provided at one end of the first mounting half ring 210a away from the rotating track 211. The end of the operating hole 213 passes through the side of the first mounting half ring 210a close to the second mounting half ring 210b to form a second locking opening. When the first mounting half ring 210a and the second mounting half ring 210b are close to each other, the first locking opening and the second locking opening are aligned to form a complete arc-shaped hole. An arc-shaped groove 214 is provided on the outer side of the first mounting half ring 210a, and the arc-shaped groove 214 is connected to the operating hole 213.

[0045] The locking assembly 250 includes a locking rod 251 slidably connected to the operating hole 213, the locking rod 251 is arc-shaped, a limiting plate 252 is integrally formed on the side of the locking rod 251 close to the arc groove 214, an arc-shaped rack 253 is fixed on the side of the limiting plate 252 away from the locking rod 251, a second driving motor 254 is fixed on the first mounting semi-ring 210a, and a second driving gear 255 is fixed on the output shaft of the second driving motor 254. The second driving gear 255 is meshed with the rack 253. When the first mounting half ring 210a and the second mounting half ring 210b are buckled, the second driving motor 254 controls the gear to rotate, and the rack 253 drives the locking rod 251 to move along the operating hole 213, and one end of the locking rod 251 can pass through the second locking port and the first locking port, and be inserted into the locking hole 212. Before the first mounting half ring 210a and the second mounting half ring 210b are separated, the first driving motor 242 controls the locking rod 251 to disengage from the locking hole 212.

[0046] Since the distance adjustment component 220 controls the first mounting half ring 210a and the second mounting half ring 210b to move in a straight line, after the first mounting half ring 210a and the second mounting half ring 210b are plugged and locked by the arc-shaped locking rod 251, the straight-line movement of the first mounting half ring 210a and the second mounting half ring 210b can be limited, thereby improving the stability of the first mounting half ring 210a and the second mounting half ring 210b when buckled.

[0047] In order to prevent the rotating half ring 231 from being separated from the rotating track 211 after the first installation half ring 210a and the second installation half ring 210b are separated, a fixing hole is opened on the outside of each installation half ring 210, and the fixing hole is connected to the rotating track 211. An electric push rod 215 is arranged on the outside of each installation half ring 210, and a fixing column is fixed to the piston end of the electric push rod 215. The fixing column can pass through the fixing hole and press against the rotating half ring 231. When the rotating half ring 231 rotates, the electric push rod 215 controls the fixing column to be separated from the rotating half ring 231. Before the first installation half ring 210a and the second installation half ring 210b are separated, the rotating half ring 231 returns to the original position. At this time, the rotating half ring 231 is pressed against by the electric push rod 215.

[0048] The distance adjustment assembly 220 includes a mounting plate 221 fixed to the upper side of the support frame 100, and two mounting blocks 222 are fixedly installed on the mounting plate 221 at intervals near the vertical side of the mounting half ring 210. A bidirectional screw rod 223 is rotatably connected between the two mounting blocks 222, and a third drive motor 224 is fixed to one end of one of the mounting blocks 222.

[0049] A mounting seat 225 is fixedly installed on each mounting half ring 210, and a rectangular guide block 2251 is formed on a side of the mounting seat 225 close to the mounting plate 221. A threaded hole 3322 is opened on the guide block 2251 in the vertical direction, and the bidirectional screw rod 223 is threadedly connected to the threaded hole 3322. The two mounting half rings 210 are symmetrically distributed on the bidirectional screw rod 223; a side of the mounting plate 221 close to the guide block 2251 and a limit strip 226 is respectively provided on both vertical sides of the guide block 2251.

[0050] By means of the distance adjustment assembly 220 , the two mounting half rings 210 can be controlled to move toward each other simultaneously in the vertical direction during operation.

By making the exhaust gas flow through the guide duct 500, the electric wires surrounded by it are heated in the guide duct 500, and during the heating process, the ice on the outside of the electric wires is melted to improve the deicing effect.

[0052] The guide duct 500 includes a lower guide plate 510 located at the lower side of the wire and an upper guide plate 520 located at the upper side of the wire. The upper guide plate 520 and the lower guide plate 510 overlap each other to form a heating hole 530 .
