Abstract

The invention provides a cable fixing device. The cable fixing device comprises two edge clamping bodies, wherein at least one groove is formed in one side surface of each edge clamping body; the opposite grooves in the two edge clamping bodies form a through hole; a gap is formed between the edge clamping bodies through elastic sleeve pipes penetrated into the through holes respectively; a cable is penetrated into the elastic sleeve pipe in an interference fit way respectively; and bolts penetrate through the edge clamping bodies and are used for clamping the elastic sleeve pipes and the cables into the through holes. According to the cable fixing device provided by the embodiment, wear of an outer insulation cover of the cable can be prevented so as to remove potential safety hazards of electric leakage and fire, and the cable can also be fixed more firmly at the same time, so that the cable fixing device has the advantages of higher safety and reliability in use.

Description

technical field [0001] The invention relates to the field of wind power generators, in particular to a cable fixing device. Background technique [0002] In wind turbines, various cables in the nacelle need to extend from the top of the tower through the interior of the tower to the bottom of the tower. Since the cables used in wind turbines are very heavy (about 2kg / m), the height of the tower is about 60m at the lowest, and more than 100m at the highest. The cable may be broken under the action of its own weight, so measures must be taken to fix the cable. [0003] The way of fixing cables in the prior art is: for the part where the cables are located at the top of the tower, a cable hanger needs to be fixedly connected to the main frame of the engine room, and the cables are wound and fixed by fixing the steel wires on the cable hanger; The part of the cable located on the side wall of the tower needs to be clamped and fixedly connected to the cable clamp connecting pla...
