Abstract

The invention provides a wind driven generator cable clamp. The cable clamp comprises an outer ring body and an inner ring body which is arranged in the outer ring body and formed by being surrounded by two blocky constructional elements, wherein a taper hole is formed by at least a portion of the inner peripheral surface of the inner ring body, which starts from one end of the inner ring body, and the inner diameters of the taper hole decrease from one end of the inner ring body towards the other end of the inner ring body. The cable clamp further comprises an inner cone which is arranged in the inner ring body and provided with a side surface of which the incline extent is consistent with the incline extent of the inner peripheral surface of the taper hole, and a lower cover plate which is arranged at the bottom of the cable clamp, connected with the outer ring body and used for supporting the inner ring body, wherein a certain interval is arranged between the inner ring body and the outer ring body under the state that a cable is clamped between the inner ring body and the outer ring body, and the inner cone automatically slide tending towards the other end of the inner ring body so as to push the inner ring body outward, and therefore the interval is adjusted. The cable clamp is reliable in performance, and the cable which is fastened is difficultly to loosen.

Description

technical field [0001] The present invention relates to a cable clamp, and more specifically relates to a wind power generator cable clamp installed in a tower of a wind power generator. Background technique [0002] A large number of cables are arranged inside the wind turbine, and these cables need to be drawn out from the nacelle, pass through the tower, and finally connect to the electrical cabinet at the bottom of the tower. The number of cables is large and the length is long, and basically all cables need to be routed from the inside of the tower. [0003] However, the height of the tower is generally more than 70 meters. When the cables are routed inside the tower, the cables must be fixed on the wall of the tower with cable clamps. Generally, a cable clamp is set every 2 meters. This is because: when the wind turbine is working, due to the wind load, the nacelle and the tower often sway and vibrate, and the cables will also sway and vibrate accordingly; after the u...
