Description

Technical Field

[0001] The utility model relates to the technical field of cable deicing, in particular to a high-altitude cable deicing device. Background Art

[0002] Aerial cables are special forms of power transmission lines that are supported by electric poles and erected in the air above the track of electric vehicles. They are used to directly supply power to them when they are in contact with them.

[0003] At present, cables installed at high altitudes are exposed to the outside air for a long time. With the alternation of hot or cold seasons, the insulation layer on the outside of the cables will gradually become rough. When the temperature of the external environment continues to drop, the water droplets accumulated on the potholes on the surface of the cables will freeze. As the rain and snow continue to fall, the ice layer on the outside of the cables will increase. In severe cases, it will cause a greater burden on the poles and even cause damage to the cables.

[0004] For high-altitude cables, how to improve the efficiency and safety of ice-breaking operations for suspended cables after they are frozen is a technical difficulty that needs to be solved. Utility Model Content

[0005] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0006] To this end, the technical solution adopted in this utility model is:

[0007] A high-altitude cable deicing device comprises a high-altitude cable, a transmission mechanism located outside the high-altitude cable, a self-propelled mechanism movably installed outside the high-altitude cable, and a deicing mechanism assembled outside the self-propelled mechanism, the self-propelled mechanism comprising a protective shell located outside the high-altitude cable, an auxiliary shaft and a transmission shaft movably installed inside the protective shell, two auxiliary rollers respectively installed outside the auxiliary shaft and the transmission shaft, a gear installed on one end of the transmission shaft, a deflection wheel movably installed outside the protective shell, a crawler belt transmission-connected between the deflection wheel and the transmission shaft, and a limiting pad movably installed inside the protective shell, the transmission mechanism comprises a photovoltaic panel installed on the top of the protective shell, a hood installed outside the photovoltaic panel, a servo motor fixedly installed in the hood, and a battery installed on the top of the hood, the deicing mechanism comprises a splint installed outside the protective shell, a reinforcing gasket fixedly installed at the outer end of the splint, a plurality of guide rods movably installed in the reinforcing gasket, an inner pad installed outside the plurality of guide rods, and a pull rod installed outside the inner pad.

[0008] In a preferred example, the utility model can be further configured as follows: the protective shell is made of stainless steel material, and the outside of the protective shell is coated with an insulating paint surface, and symmetrically distributed vertical grooves are provided on both sides of the protective shell, both ends of the auxiliary shaft and the transmission shaft are connected with positioning bolts and gaskets, and the transmission shaft passes through one end of the protective shell and is fixedly installed with an auxiliary rotation end.

[0009] By adopting the above technical solution, the protective shell is movably installed on the outside of the aerial cable, and the top of the aerial cable is limited by two auxiliary rollers, and the bottom of the aerial cable is constrained by a limiting pad. When the transmission shaft cooperates with one of the auxiliary rollers to actively rotate, the two auxiliary rollers clamped on the outside of the aerial cable can move stably.

[0010] In a preferred example, the utility model can be further configured as follows: transverse holes are opened in the fan-shaped end plates at both ends of the gear, and rivets are movably installed in the transverse holes of the fan-shaped end plates, the inner end of the deflection wheel is connected with a pin, and a column head is fixedly installed on the rotating wheel at the end of the deflection wheel away from the protective shell, and the column head is located at a position of the rotating wheel away from the center of the circle.

[0011] By adopting the above technical solution, the gear is fixedly installed on one end of the transmission shaft that passes through the outside of the protective shell by rivets. At this time, the gear is close to the auxiliary rotating end on the outer end of the transmission shaft. As the servo motor runs, its internal transmission shaft will cooperate with the gear transmission gear to rotate stably. At the same time, the auxiliary rotating end will also cooperate with the track to drive the deflection wheel. At this time, the pull rod movably installed on the external column head of the deflection wheel can provide high-frequency driving force to multiple guide rods.

[0012] In a preferred example, the utility model can be further configured as follows: the terminal at the bottom of the photovoltaic panel is connected to the terminal on the battery through a wire, and the terminal on the battery is connected to the pole of the servo motor through a wire.

[0013] By adopting the above technical solution, since the aerial cable is in a suspended state, when the device moves laterally along the outside of the aerial cable, the photovoltaic panel located on the top of the protective shell can receive light in time, and at the same time cooperate with the battery to store the converted photoelectric energy. At this time, the self-propelled mechanism as a whole can move stably under the continuous power supply of the servo motor.

[0014] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0015] 1. The utility model controls the operation of the servo motor, and its internal transmission shaft will cooperate with the gear to continuously transmit the gear, the track and the deflection wheel to rotate. At the same time, the splint located outside the protective shell can push the reinforcing gasket outward, and the deflection wheel will drive the pull rod to extend back and forth, and the end of the pull rod away from the deflection wheel will drive the inner pad and multiple guide rods to vibrate at high frequency. At this time, the ice layer attached to the outside of the cable will be forcibly broken by the multiple guide rods, and at the same time, it will not cause damage to the insulation layer on the outside of the aerial cable.

[0033] The self-propelled mechanism 200 includes a protective shell 210, an auxiliary shaft 220, a transmission shaft 230, an auxiliary roller 240, a gear 250, a deflection wheel 260, a track 270 and a limit pad 280.

[0034] Specifically, the protective shell 210 is located outside the aerial cable 100, the auxiliary shaft 220 and the transmission shaft 230 are movably installed on the inner side of the protective shell 210, the two auxiliary rollers 240 are respectively installed on the outside of the auxiliary shaft 220 and the transmission shaft 230, the gear 250 is installed on one end of the transmission shaft 230, the deflection wheel 260 is movably installed on the outside of the protective shell 210, the crawler 270 is transmission-connected between the deflection wheel 260 and the transmission shaft 230, and the limiting pad 280 is movably installed on the protective shell 210.

[0035] The limiting pad 280 is locked in the inner cavity of the protective shell 210 by pre-adjusting two pre-tightening bolts. At this time, the locked limiting pad 280 can cooperate with the two auxiliary rollers 240 to clamp the bottom and top of the aerial cable 100 in real time. At the same time, when the cable is assembled, the ice-breaking reinforcing gasket 420 and the inner pad 440 and the combined multiple guide rods 430 are movably assembled outside the cable between two adjacent poles, and then the outer ends of the two clamping plates 410 are assembled in the slots outside the protective shell 210. As the servo motor 330 runs, its internal transmission shaft will cooperate The gear continuously drives the gear 250, the track 270 and the deflection wheel 260 to rotate, and the two auxiliary rollers 240 can stably move laterally along the outside of the aerial cable 100. At the same time, the splint 410 located outside the protective shell 210 can push the reinforcing gasket 420 outward, and the deflection wheel 260 will drive the pull rod 450 to extend back and forth, and the end of the pull rod 450 away from the deflection wheel 260 will drive the inner pad 440 and multiple guide rods 430 to vibrate at high frequency. At this time, the ice layer attached to the outside of the cable will be forcibly broken by the multiple guide rods 430.

[0036] Embodiment 2:

[0037] Combination Figure 3-Figure 7 As shown, on the basis of embodiment one, the protective shell 210 is made of stainless steel material, and the outside of the protective shell 210 is coated with an insulating paint surface, and symmetrically distributed vertical grooves are provided on both sides of the protective shell 210, and positioning bolts and gaskets are connected to both ends of the auxiliary shaft 220 and the transmission shaft 230, and an auxiliary rotation end is fixedly installed on one end of the transmission shaft 230 that passes through the outside of the protective shell 210, and transverse holes are provided in the fan-shaped end plates at both ends of the gear 250, and rivets are movably installed in the transverse holes of the fan-shaped end plates, the inner end of the deflection wheel 260 is connected with a pin, and a column head is fixedly installed on the rotating wheel of the deflection wheel 260 away from the protective shell 210, and the column head is located at the part of the rotating wheel away from the center of the circle.

[0038] The protective housing 210 is movably installed on the outside of the aerial cable 100, and the two auxiliary rollers 240 are used to limit the top of the aerial cable 100, and the limiting pad 280 is used to constrain the bottom of the aerial cable 100. The gear 250 is fixedly installed on the end of the transmission shaft 230 that passes through the outside of the protective housing 210 with rivets. At this time, the gear 250 is close to the auxiliary end of the outer end of the transmission shaft 230. As the servo motor 330 runs, its internal transmission shaft will cooperate with the gear transmission gear 250 to rotate stably. At the same time, the auxiliary rotation end will cooperate with the track 270 to drive the deflection wheel 260. At this time, the pull rod 450 movably installed on the external column head of the deflection wheel 260 can provide a high-frequency driving force to the multiple guide rods 430, thereby ensuring that the ice layer accumulated on the outside of the aerial cable 100 is actively broken. When the transmission shaft 230 cooperates with one of the auxiliary rotation rollers 240 to actively rotate, the two auxiliary rotation rollers 240 clamped on the outside of the aerial cable 100 can move stably, and at the same time provide a sufficiently stable pressure-bearing platform for the vibration of the guide rod 430.

[0039] Embodiment three:

[0040] Combination Figure 1-Figure 6 and Figure 7 As shown, based on the first embodiment, the terminals at the bottom of the photovoltaic panel 310 are connected to the terminals on the battery 340 through wires, and the terminals on the battery 340 are connected to the poles of the servo motor 330 through wires.

[0041] Since the aerial cable is in a suspended state, when the device moves laterally along the outside of the aerial cable 100, the photovoltaic panel 310 located on the top of the protective shell 210 can receive light in time, and at the same time cooperate with the battery 340 to store the converted photoelectric energy. At this time, the self-propelled mechanism 200 as a whole can move stably under the continuous power supply of the servo motor 330, thereby ensuring that the aerial cable 100 removes the ice layer without being damaged.

[0042] The working principle and use process of the utility model are as follows: multiple guide rods 430 are uniformly fixed to the outside of the inner pad 440 by bolts in advance, and then the multiple guide rods 430 after combination are movably installed in the transverse groove on the inner side of the reinforcing pad ring 420, and then the two clamping plates 410 are fixedly installed on both sides of the outside of the reinforcing pad ring 420, and one end of the pull rod 450 is fixed to the outside of the inner pad 440, and the other end of the pull rod 450 is movably installed on the column head outside the deflection wheel 260. At this time, the combined de-icing mechanism 400 will be symmetrically distributed with the protective shell 210 as a whole, and the two auxiliary rollers 240 located at the top of the inner cavity of the protective shell 210 will fit the top of the aerial cable 100. At this time, it is necessary to manually adjust the locking bolts on the outside of the two limiting pads 280 until the groove on the top of the limiting pad 280 is lifted to the bottom of the aerial cable 100, and finally fix the locking bolts;

[0043] During use, as the servo motor 330 is powered on, the gear on its internal transmission shaft will adapt to the transmission gear 250. At this time, the gear 250 will cooperate with the transmission shaft 230 and one of the auxiliary rollers 240 to rotate along the top of the aerial cable 100. At this time, the two auxiliary rollers 240 can slowly move laterally along the top of the aerial cable 100. At the same time, the transmission shaft 230 drives the track 270, and the track 270 also drives the deflection wheel 260 to rotate, thereby providing reciprocating traction to the pull rod 450. At this time, the pull rod 450 will cooperate with the inner pad 440 to perform high-frequency vibration on multiple guide rods 430. At this time, the ice layer accumulated on the surface of the aerial cable 100 can be broken without causing damage to the aerial cable 100.

[0044] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
