Description

Technical Field

[0001] One or more embodiments of the present specification relate to the field of cable protection technology, and in particular, to an ice and snow clearing device for high-voltage cables. Background Art

[0002] Cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. The manufacturing of wires and cables is completely different from the production method of most electromechanical products. Electromechanical products usually use parts to assemble into components, and multiple components are assembled into a single product, and the product is measured by the number of units or pieces. Wires and cables are measured in length. All wires and cables start with conductor processing, and insulation, shielding, cabling, sheathing, etc. are added layer by layer on the outer periphery of the conductor to make wire and cable products. The more complex the product structure, the more layers are superimposed.

[0003] With the rapid development of underground power cable laying projects, higher requirements are put forward for cable protection. Cable protection sleeves are made of polyethylene PE and high-quality steel pipes through sandblasting and shot blasting pretreatment, plastic dipping or coating, and heating and curing processes. It is the most commonly used electrical insulation tube for protecting wires and cables. It is widely used because of its good insulation performance, high chemical stability, no rust, no aging, and adaptability to harsh environments.

[0004] The rated voltage of the cable is equal to or greater than the rated voltage of the network in which it is located, and the maximum working voltage of the cable shall not exceed 15% of its rated voltage. Except for copper core cables in places where they are to be moved or vibrated violently, aluminum core cables are generally used. Cables laid in cable structures should be bare armored cables or aluminum-clad bare plastic sheathed cables. Direct buried cables should use armored cables with sheaths or aluminum-clad bare plastic sheathed cables. Heavy rubber sheathed cables should be used for mobile machinery. Direct burial is generally not used in corrosive soils, otherwise special anti-corrosion cables should be used. In places with corrosive media, corresponding cable sheaths should be used. When laying cables vertically or in places with large height differences, non-drip cables should be used. Rubber insulated cables should not be used when the ambient temperature exceeds 40°C.

[0005] In the winter, overhead cables in the north are often covered with a large amount of ice and snow. In the prior art, they are generally cleaned manually at regular intervals to prevent the accumulation of too much ice and snow and the occurrence of cable breakage. However, manual cleaning is incomplete and very dangerous. In the prior art, the cleaning equipment is often complex in overall structure and its own weight often causes a burden on the cable. In the prior art, it is generally carried out by shoveling snow, but this method often causes a large amount of cable skin to be cut, which cannot meet the requirements of the prior art. Summary of the invention

[0006] In view of this, an object of one or more embodiments of the present specification is to provide an ice and snow clearing device for a high-voltage cable to solve the problem.

[0007] Based on the above purpose, one or more embodiments of the present specification provide a snow and ice clearing device for a high-voltage cable, comprising: a main body, an inner plate inlaid on the inner side of the main body, and a heating plate inlaid at the center of the outer periphery of the main body.

[0009] Wind hoods are inlaid on both sides of the inner hole, and a hot air blower is inlaid on one end of the wind hood.

[0010] Preferably, the ice and snow clearing equipment further comprises: connecting plates and guide wires, the two connecting plates are rotatably connected to a central turntable at the center positions of adjacent surfaces, and the guide wires are wound around the periphery of the central turntable.

[0011] Preferably, the connecting piece further comprises: a guide wheel, and the connecting pieces on both sides of the central turntable are rotatably connected with guide wheels.

[0012] Preferably, the connecting piece further comprises: a second motor and a motor bracket, the motor bracket is mounted on the connecting piece on one side of the central turntable by bolts, and the second motor is mounted in the motor bracket.

[0014] Preferably, the main body further comprises: a protective plate, and protective plates are welded to both ends of the roller.

[0015] Preferably, the main body further comprises: air holes, and the inner plate is provided with air holes at locations corresponding to the hot air blower.
