Technical Field

[0001] The present application relates to the technical field of power maintenance and protection, and in particular to a deicing device for power cables. Background Art

[0002] Failures caused by icing on power lines have always been one of the serious disasters in power systems at home and abroad. In order to avoid serious power supply accidents caused by ice on cables, it is necessary to de-ice the cables in a timely manner.

[0003] The existing de-icing device of the power cable is hung on the cable through a manual climbing tower, and then the de-icing device is moved along the cable by a motor-driven roller abutting the cable. The de-icing device removes the ice layer on the cable by knocking, cutting, heat melting and vibration to complete the de-icing operation of the cable.

[0004] Although the above-mentioned deicing device can remove the ice layer on the cable, it requires manual climbing of the tower frame to be installed on the cable, which increases the installation difficulty and installation time of the deicing device and the cable, resulting in low installation efficiency of the deicing device. Summary of the invention

[0005] In order to enable a deicing device to be conveniently installed on a cable and to improve the installation efficiency of the deicing device, the present application provides a deicing device for a power cable.

[0006] The present application provides a deicing device for power cables, which adopts the following technical solution: A deicing device for a power cable comprises a connecting plate, a drone assembly and a deicing assembly, wherein the drone assembly and the deicing assembly are respectively connected to two sides of the connecting plate, the drone assembly is used to drive the deicing assembly close to an ice-covered cable, the deicing assembly comprises a clamping portion and a deicing portion, the clamping portion is connected to the connecting plate and is used to clamp the ice-covered cable, and the deicing portion is arranged on the clamping portion and is used to remove the ice layer on the cable.

[0007] By adopting the above technical solution, the drone component can carry the de-icing component to fly high and close to the ice-covered cable. After the de-icing component is close to the ice-covered cable, the clamping part clamps the ice-covered cable, so that the de-icing part can be quickly installed on the ice-covered cable, so that the de-icing part can easily start to remove the ice layer on the cable, so that the installation of the de-icing device does not require manual climbing of the tower, reducing the difficulty of installing the de-icing device on the ice-covered cable, and reducing the installation time of the de-icing device, so that the de-icing device can be easily installed on the cable, thereby improving the installation efficiency of the de-icing device.

[0008] Optionally, the clamping part includes a clamping shaft, a clamping plate and an electric telescopic part. The clamping shaft, the clamping plate and the electric telescopic part are symmetrically arranged in two. The clamping shaft is rotatably connected to the connecting plate. The clamping plate corresponds to the clamping shaft one by one. One side of the clamping plate is fixedly connected to the clamping shaft. The two electric telescopic parts are respectively located on the sides of the two clamping plates away from each other. The electric telescopic part is hinged between the connecting plate and the clamping plate. The electric telescopic part is used to drive the two clamping plates to clamp on the ice-covered cable.

[0009] By adopting the above technical solution, the electric telescopic part can drive the clamping plate to rotate around the rotation axis of the clamping shaft. Under the flight action of the UAV component, the ice-covered cable can be easily placed between the two clamping plates. The clamping plates are driven by the electric telescopic part so that the two clamping plates can be clamped on the ice-covered cable, thereby making it easy for the de-icing part to be quickly installed on the ice-covered cable through the clamping action of the clamping plates.

[0010] Optionally, the de-icing part includes an ice-breaking hammer and an ice-breaking rod. There are two groups of ice-breaking hammers, which are respectively arranged on one side of two clamping plates close to each other. There are multiple ice-breaking hammers in each group, and the multiple ice-breaking hammers are symmetrically arranged. The hammer rods of the ice-breaking hammers are hinged on the clamping plates. There are multiple ice-breaking rods, which are respectively arranged between two symmetrical ice-breaking hammers. Both ends of the ice-breaking rod are slidably connected to the hammer rods of the two ice-breaking hammers.

[0011] By adopting the above technical solution, when the clamping plate is clamped on the ice-covered cable, the sliding ice-breaking rod is close to the ice-covered cable, and the two ends of the ice-breaking rod slide along the hammer rod of the ice-breaking hammer, so that the two symmetrical ice-breaking hammers swing towards each other, so that the hammer head of the ice-breaking hammer can strike the ice-covered cable, so that the ice layer on the cable can fall off under the striking action.

[0012] Optionally, each group of ice-breaking hammers is connected to an ice-breaking driving unit, the ice-breaking driving unit includes an ice-breaking telescopic rod, the ice-breaking telescopic rod is fixedly arranged on a side of the clamping plate away from the other clamping plate, the movable end of the ice-breaking telescopic rod is slidably penetrated on the clamping plate, the movable end of the ice-breaking telescopic rod is fixedly connected to an ice-breaking connecting rod, and the ice-breaking connecting rod is fixedly connected to the ice-breaking rods connected to all the ice-breaking hammers of the corresponding group; An electromagnet and a magnetic block are arranged in the rodless cavity of the ice-breaking telescopic rod.

An elastic rope is fixed between the electromagnet and the magnetic block. The elastic rope is used to drive the magnetic block close to the electromagnet. The electromagnet is electrically connected to an intermittent power supply controller. The intermittent power supply controller is used to control the intermittent power supply of the electromagnet. The polarity of the electromagnet and the magnetic block on the side close to each other in the energized state is the same.

[0013] By adopting the above technical scheme, the intermittent power supply controller can control the intermittent power supply of the electromagnet, so that the magnetic thrust between the electromagnet and the magnetic block exists intermittently. When the electromagnet is energized, the magnetic thrust between the electromagnet and the magnetic block can drive the ice-breaking telescopic rod to extend, and the elastic rope can accumulate elastic force. The ice-breaking telescopic rod drives the ice-breaking rod to slide through the ice-breaking connecting rod, so that the ice-breaking hammer can hit the ice-covered cable. When the electromagnet is de-energized, the elastic rope between the electromagnet and the magnetic block can drive the ice-breaking telescopic rod to retract through elastic force, so that the ice-breaking hammer is away from the ice-covered cable, so that during the intermittent power supply of the electromagnet, the ice-breaking hammer can cyclically hit the ice-covered cable.

[0014] Optionally, support parts are provided at both ends of the clamping plate, and the support parts include support rods, support plates and support springs. There are more than two support rods, support plates and support springs, and they correspond to each other one by one. The support rod is slid through the clamping plate, the support plate is fixed to the end of the support rod away from the other clamping plate, the support spring is fixed between the support plate and the clamping plate, and the support spring is used to drive the end of the support rod away from the support plate to support on the ice-covered cable.

[0015] By adopting the above technical scheme, the support rods on the two clamping plates can abut against the ice-covered cables when the clamping plates clamp the ice-covered cables. Under the elastic force of the support springs, the support rods provide supporting force to the clamping plates with the ice-covered cables as support points. With the cooperation of all the support rods at both ends of the two clamping plates, the clamping plates can be in an elastically supported state relative to the ice-covered cables. On the one hand, the vibration transmitted to the clamping plates by the ice-covered cables can be buffered by the support springs. On the other hand, with the cooperation of the support rods and the support springs, the two ends of the clamping plates can be stably supported on the ice-covered cables and the cables without ice layers, respectively, so that the positions of the cables relative to the clamping plates can always be in a stable state.

One end of the push rod is fixedly connected to the clamping rotating shaft. The two-way telescopic rod is located between the two push rods, and the two movable ends of the two-way telescopic rod are respectively hinged to the ends of the two push rods away from the clamping rotating shaft. The rack is fixedly connected to the two-way telescopic rod and slidably penetrated on the connecting plate. The rack is meshed with the gear, and the gear is coaxially fixed to the rotating shaft. When the two clamping plates are abutted, the connecting rod is parallel to the connecting plate.

[0017] By adopting the above technical solution, when the electric telescopic part drives the clamping plate to swing, the clamping plate drives the clamping shaft to rotate, the clamping shaft drives the push rod to rotate, the push rod drives the two-way telescopic rod to move, the two-way telescopic rod drives the rack to slide, the rack drives the gear to rotate, and the gear drives the connecting rod and the drone body to swing through the rotating shaft, so that the connecting rod is parallel to the connecting plate, so that the drone body can be changed from a vertical setting to a horizontal setting, and the horizontally set drone body can pull the connecting plate and the clamping plate to move along the cable, so that the drone body can not only carry the deicing assembly close to the ice-covered cable, but also pull the deicing assembly to move along the cable.

[0018] Optionally, a cable groove is provided on the steering side of the drone body. When the connecting rod is parallel to the connecting plate, the cable is inserted into the cable groove. A hot melt component is provided on the drone body. The hot melt component includes a heating wire. Two heating wires are provided and symmetrically arranged on both sides of the cable groove. The heating wires are connected to the drone body.

[0019] By adopting the above technical solution, after the main body of the drone swings, the cable can be inserted into the cable groove, and the two heating wires on both sides of the cable groove can heat and melt the ice layer on the cable, reducing the difficulty of removing the ice layer on the cable by the icebreaker.

[0020] Optionally, both ends of each of the heating wires are slidably arranged in a slide groove provided on the main body of the drone, the sliding directions of the two heating wires are directions of approaching or moving away from each other, a variable resistance slide bar is embedded in the bottom of the slide groove, the ends of the heating wires abut against the variable resistance slide bar and are electrically connected, when the heating wire is located at one end of the slide groove away from the cable groove, the heating wire and the variable resistance slide bar are in an open circuit state, and when the heating wire is located at one end of the slide groove close to the cable groove, the heating wire and the variable resistance slide bar are in a short circuit state; The end of the heating wire close to the bottom of the cable groove is hinged with a swing rod, and the ends of the two swing rods away from the heating wires are hinged with an adjustment rod. The adjustment rod is slidably connected to the drone body along the opening direction of the cable groove, and the end of the adjustment rod away from the swing rod is inserted into the cable groove from the bottom of the cable groove; A thermal melt spring is fixed between the two swing arms, which is used to drive the two swing arms to swing away from each other; when the cable is inserted into the cable groove without an ice layer, the end of the adjustment rod abuts against the cable, and the heating wire is located at the end of the slide groove away from the cable groove.

[0021] By adopting the above technical solution, the thickness of the ice layer on the cable determines the sliding displacement of the adjusting rod after the cable is inserted into the cable groove. The thicker the ice layer, the greater the sliding displacement of the adjusting rod. At the same time, the amplitude of the swing of the two swing rods driven by the adjusting rod is also greater, so that the heating wire is closer to the cable groove, and the heating wire is energized through the variable resistance slider. Under the conductive effect of the variable resistance slider, the closer the heating wire is to the cable groove, the greater the current flowing through the heating wire. Therefore, when the thickness of the ice layer is greater, the heating effect of the heating wire on the ice layer is more obvious, so that the heating of the ice layer by the heating wire can be automatically regulated according to the thickness of the ice layer.

[0022] Optionally, a solar battery is fixedly provided on the drone body, and the solar battery is electrically connected to the drone body, the electric telescopic member, the intermittent power supply controller and the variable resistance slider respectively.
