Description

A cable fixing bracket in a tower of a wind power generating set

technical field

The utility model relates to a cable fixing bracket in a tower tube of a wind power generating set, in particular to a cable fixing bracket in a tower tube of a megawatt wind power generating set.

Background technique

In wind turbines, especially megawatt-scale wind turbines, there are many cables hanging vertically in the tower. When the wind turbine is yawed, there will be a large amount of shaking and vibration, which will cause collision damage to the cables and need to be restrained. In the existing wind turbine tower design, many manufacturers have not paid enough attention to this, and some have designed a rigid steel structure cantilever bracket, which is heavy, has no elasticity, and has poor shock absorption. In addition, the general cable sheath is inconvenient to assemble when installing the cable. Most of them are Huff type, and the bolts are fastened. The cable bracket has no adjustment ability in the height range of the tower. When the height position is reached, the hole can only be re-drilled for installation.

Utility model content

The technical problem to be solved by the utility model is: to overcome the deficiencies in the prior art, to provide a cable fixing bracket in the tower of the wind power generating set, to restrain the cables vibrating and shaking in the tower of the wind turbine in the working state, and to prevent the cables from contacting the tower. Wall collision prevents cables from being damaged due to mutual collision between cables; at the same time, it is easy to assemble, the installation position can be adjusted in the height direction, the overall weight is light, and the shock absorption performance is good.

The technical scheme adopted by the utility model to solve the technical problem is: a cable fixing bracket in the tower tube of a wind power generating set, which has a cable sheath and an expansion ring that can be tightened on the inner wall of the tower tube, and a spring is opened on the outer periphery of the cable sheath The cable sheath hoop spring is installed in the spring groove, and the cable sheath hoop spring and the expansion ring are connected by a tension spring.

Further, the cable sheath has a longitudinal opening, and more than one semicircular longitudinal groove is opened on the outer periphery of the cable sheath.

Further, the connection mode between the cable sheath hoop spring and the expansion coil through extension springs is: the cable sheath hoop spring and the expansion coil are connected through three horizontal tension springs.

Further, the expansion ring has a tension adjustment structure.

Further, the tension adjustment structure is as follows: there is a threaded groove on the bending part at the joint at one end of the expansion ring, and a threaded hole is opened on the bending part at the joint at the other end of the expansion ring. Screws pass through the threaded holes into the threaded grooves.

Further, the expansion ring is composed of two semicircular expansion rings, the inner connection of the two semicircular expansion rings is connected by a hinge pin, and the outer connection of the two semicircular expansion rings is connected by a tension adjustment mechanism. Easy disassembly and assembly.

The beneficial effects of the utility model are: the cable sheath of the utility model has a longitudinal opening, which is easy to put into the cable, and the cable sheath is tightened by the cable sheath hoop spring. The semicircular longitudinal grooves on the outer periphery of the cable sheath increase the opening and closing flexibility, which facilitates the opening and closing of the cable sheath during assembly. Three tension springs are used to tighten the cable sheath and the expansion ring, which are elastic, good shock absorption and light in weight. By adjusting the adjusting screw, the expansion ring is tightened on the inner wall of the tower tube, so as to realize the fixing of the expansion ring and the inner wall of the tower tube at any height.

Detailed ways

The utility model is described further in conjunction with accompanying drawing now. These drawings are simplified schematic diagrams only to illustrate the basic structure of the utility model in a schematic way, so they only show the configurations related to the utility model.

As shown in Figure 1 and Figure 2, a cable fixing bracket in the tower of a wind power generating set has a cable sheath 1 and an expansion ring 2 that can be tightened on the inner wall of the tower. A cable sheath hoop spring 3 is installed in the groove, and the cable sheath hoop spring 3 and the expansion ring 2 are connected by three horizontal extension springs 4 . The cable sheath 1 hoop spring is fixed with a cable cover hook 6, and the expansion ring 2 is fixed with an expansion ring hook plate 7. One end of the extension spring 4 is connected with the cable sleeve hook 6, and the extension spring 4 other end is connected with the expansion ring hook plate 7.

As shown in Figure 2, the cable sheath 1 has a longitudinal opening, and the outer periphery of the cable sheath 1 is provided with 5 semicircular longitudinal grooves.

As shown in Figure 3 and Figure 4, the expansion ring 2 is composed of two semicircular expansion rings, the inner connection of the two semicircular expansion rings is connected by a hinge pin, and the outer connection of the two semicircular expansion rings is connected by a tension adjustment mechanism. The tightening adjustment structure is as follows: there is a threaded groove on the bending part at the joint at one end of the expanding ring 2, and a threaded hole is opened on the bending part at the joint at the other end of the expanding ring 2, and the adjusting screw passes through the threaded hole to the threaded groove.
