De-icing devices for cables

Abstract

The invention provides a deicing device for a cable line. The deicing device comprises a deicing main piece, wherein an air storage bottle is arranged at an upper part of the deicing main piece, helium is stored in the air storage bottle, an upwards-sunken accommodating cavity is formed in the bottom of the deicing main piece, deicing equipment is arranged at a middle part of an inner side of theaccommodating cavity and comprises an air cylinder, a hammer is arranged at an inner side wall of the air cylinder, is in close contact with the air cylinder and can slide along the inner side wall ofthe air cylinder, the hammer and the top and the inner side wall of the air cylinder form an extrusion cavity, a through hole is formed in the top of the air cylinder, and the extrusion cavity communicates with the air storage bottle via the through hole. The accommodating cavity is formed in the deicing main piece, the deicing equipment is arranged in the accommodating cavity, an air bag is driven and extruded to extrude coated iced at an upper part of the cable line by the helium of the air storage bottle, a driving motor is not needed, the cable line or the power of the cable line is not depended, and the deicing device also can normally work at power-failure moment caused by severe weather; and the deicing device is not the driving motor or other mechanical structures, the deicing device is simple in structure and lighter in weight, and a relatively large load cannot be generated for the cable line.

Description

technical field [0001] The invention relates to the field of power grid accessories, in particular to a deicing device for cables. Background technique [0002] At present, during the use of cables, there will be ice and snow weather, and the cables exposed to the outside are prone to ice coating. These ice coatings will greatly increase the burden on the cables and towers, and in severe cases, it will cause tower collapse, wire jumping or tripping. . To avoid problems caused by icing, de-icing work is necessary. [0003] In the past, manual knocking was used for deicing operations, which had the disadvantages of heavy workload, low efficiency, and the risk of electric shock. In order to improve deicing efficiency and ensure personnel safety, deicing devices were often used. At present, the Chinese patent with the patent application number 201510024028.3 discloses a three-roller suspension cable deicing device, which uses a drive motor to drive the traveling wheels to move...
