Abstract
The utility model relates to a cable fixing bracket used in a tower tube of a wind turbine generator system, comprising a cable sheath, an expansion ring, wherein more than one spring slots are arranged at the periphery of the cable sheath; the spring slots are internally provided with cable sheath hoop springs; and the cable sheath hoop springs are connected with the expansion ring by pulling springs. The cable sheath is provided with a longitudinal through hole; and more than one semi-round longitudinal slots are arranged at the periphery of the cable sheath. In the utility model, as the longitudinal through hole is arranged on the cable sheath, the cable can be fed in the cable sheath easily; and the semi-round longitudinal slot is arranged at the periphery of the cable sheath so as to increase the opening and closing elasticity, thus facilitating the opening and closing of the cable sheath during the assembling process. The cable sheath and the expansion ring are tightly pulled by three pulling springs, thus having good elasticity, good damping performance and light weight. An adjusting screw can be adjusted so that the expansion ring can be tightly expanded on the internal wall of the tower tube, thus realizing the aim of fixing the expansion ring and the internal wall of the tower tube at any height.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of wind turbine generator tower tube inner cable fixed support, but have the piston ring of cable cover(ing) tensioner on tower tube inwall, the cable cover(ing) periphery has spring groove, the cable cover(ing) garter spring is installed in the spring groove, is connected by extension spring between cable cover(ing) garter spring and the piston ring.
Further, described cable cover(ing) has vertical port, and described cable cover(ing) periphery has more than one semicircle cannelure.
Further, the connected mode that is connected by extension spring between described cable cover(ing) garter spring and the piston ring is: be connected by three horizontal extension springs between described cable cover(ing) garter spring and the piston ring.
Further, described piston ring has the tensioner adjustment structure.
Further, described tensioner adjustment structure is: have thread groove on the bending part at described piston ring one end connector place, have screwed hole on the bending part of described piston ring other end joint, adjustment screw is passed screwed hole to thread groove.
Further, described piston ring is made up of two semicircle piston rings, and the interior junction of two semicircle piston rings adopts hinge pin to connect, and the outer junction of two semicircle piston rings is connected by the tensioner governor motion.Easy accessibility, convenient for assembly.
The beneficial effects of the utility model are: cable cover(ing) of the present utility model has been opened a vertical port, is easy to put into cable, with cable cover(ing) garter spring banding cable cover(ing).The semicircle cannelure that the cable cover(ing) periphery has increases folding elasticity, the folding of cable cover(ing) when being convenient to assemble.With three extension spring tensions, flexible, shock-absorbing is good, and is in light weight between cable cover(ing) and the piston ring.Make the piston ring tensioner on tower tube inwall by regulating adjustment screw, realize fixing on piston ring and the tower tube inwall arbitrary height.
