Detailed Description
The first embodiment is as follows:
as shown in fig. 1, this embodiment introduces a power output system in a wind power tower, power output system sets up in the inside of a tower section of thick bamboo 9, including a plurality of generating line pipes 1, flexonics 2 and installing support 3, and a plurality of installing support 3 fixed connection are at the inside wall of a tower section of thick bamboo 9, and installing support 3 is vertical evenly to be set up, and generating line pipe 1 fixed mounting is on installing support 3, then connects through flexonics 2 between the generating line pipe 1. When a tower barrel 9 rocks, the bus tube 1 and the mounting bracket 3 can rock along with the tower barrel 9, and in the process of rocking, the dislocation between the bus tubes 1 is adjusted through the flexible connection 2, so that the internal stress between electric energy transmission systems is reduced.
As shown in the combined drawing 1, when the tower barrel 9 rocks, the bus tube 1 and the mounting bracket 3 also rock, generally one bus tube 1 is provided with two mounting brackets 3 for supporting, and along with the different directions of the tower barrel 9, the deformation degree between the bus tube 1 and the two mounting brackets 3 is different. When the tower barrel 9 shakes towards the direction in which the mounting brackets 3 are far away from the bus tubes 1, the deformation of the distance between the mounting brackets 3 is smaller than that of the bus tubes 1; when the tower barrel 9 rocks towards the direction that the bus tube 1 is far away from the mounting brackets 3, the deformation of the bus tube 1 is smaller than that between the mounting brackets 3. Because the deflection between the installing support 3 is asynchronous with the deflection of generating line pipe 1, consequently can produce great stress often between generating line pipe 1 and the installing support 3 at the in-process that tower section of thick bamboo 9 rocked, lead to generating line pipe 1 to warp, trouble such as mounting screw is not hard up, and the fault rate is higher.
In order to solve the above problem, as shown in fig. 1, the mounting bracket 3 is configured as a fixed bracket 31, an elastic bracket 32 and a mounting seat 33, the mounting seat 33 is connected to both the fixed bracket 31 and the elastic bracket 32, and generally, the fixed bracket 31 is located above the elastic bracket 32. After the elastic support 32 and the fixed support 31 are arranged, the elastic support 32 can be elastically deformed, so that the distance between the elastic support 32 and the fixed support 31 is adjusted, the internal force between the bus pipe 1 and the fixed support 31 and the elastic support 32 is reduced, and the failure rate of the power transmission system is reduced.
The resilient support 32 may be of various constructions and forms, and this embodiment is described by way of reference. As shown in fig. 2, in the present embodiment, the elastic bracket 32 includes a connecting plate 321, an elastic plate 322 and a mounting plate 323, the elastic plate 322 is fixedly disposed below two ends of the connecting plate 321, and two ends of the mounting plate 323 are respectively and fixedly connected below the elastic plate 322. The elastic plate 322 is a C-shaped plate in this embodiment, and of course, the shape of the elastic plate 322 is not limited to the C-shaped plate, but may be other structures with elasticity, such as a spring. Utilize elastic plate 322's deformation effect, when tower section of thick bamboo 9 produces and rocks, the distance between connecting plate 321 and the fixed bolster 31 changes asynchronous with the deflection of generating line pipe 1, generating line pipe 1 will drive mounting panel 323 relative connection plate 321 and produce relative movement this moment, compensate with the change volume between connecting plate 321 and the fixed bolster 31, elastic plate 322 can produce deformation this moment and provide the compensation volume, and also can play the effect of supporting generating line pipe 1, thereby greatly reduced generating line pipe 1 and fixed bolster 31 and the internal stress between the elastic support 32, thereby reduce power transmission system's fault rate.

When a tower section of thick bamboo 9 orientation was close to the direction slope that installing support 3 kept away from bus-bar tube 1, the deflection of distance was less than the amount that bus-bar tube 1 warp between fixed bolster 31 and the elastic support 32, and bus-bar tube 1 just can drive the relative mounting panel 323 of overlap joint fixing base 332 and upwards slide this moment, and sliding sleeve 3232 slides in mounting hole 3231 promptly to supply the deflection of bus-bar tube 1, reach the effect that reduces bus-bar tube 1 stress. Meanwhile, after the arrangement, when the tower tube 9 is inclined towards the direction of the mounting bracket 3 away from the bus bar tube 1, the elastic plate 322 of the elastic bracket 32 does not generate compression deformation, so that the fatigue damage strength of the elastic plate 322 can be greatly reduced, and because the elastic plate 322 only generates tensile deformation when the tower tube 9 is inclined towards the direction of the bus bar tube 1 away from the mounting bracket 3, the service life of the elastic plate 322 can be greatly prolonged.
As shown in fig. 2, the clamping fixing seat 333 includes a fixing seat 3331 and a movable seat 3332, the fixing seat 3331 is fixedly connected to the fixing support 31, and the movable seat 3332 and the fixing seat 3331 are detachably and fixedly connected by bolts to clamp the bus bar pipe 1.

At this moment at the in-process of installation generating line pipe 1, can insert the overlap joint hole 3321 of overlap joint fixing base 332 with the lower extreme of generating line pipe 1 in for the overlap joint portion 11 and the overlap joint hole 3321 overlap joint of generating line pipe 1 realize the effect of quick location generating line pipe 1 position, later recycle joint fixing base 333 and generating line pipe 1 fixed connection, accomplish generating line pipe 1's installation, can the fixed degree of difficulty of greatly reduced generating line pipe 1 location and installation, thereby promote the efficiency of installation.
As shown in fig. 4, the lower end of the overlapping part 11 is integrally connected with an installation part 111, the diameter of the outer peripheral surface of the installation part 111 is smaller than that of the outer peripheral surface of the overlapping part 11, the installation part 111 and the overlapping hole 3321 are inserted and matched with each other, and the overlapping part 11 is overlapped with the overlapping hole 3321. After the below of overlap joint portion 11 sets up installation department 111, installation department 111 can insert in the overlap joint hole 3321, and overlap joint portion 11 can the overlap joint in the top of overlap joint hole 3321, is favorable to fixing a position bus-bar pipe 1 at the in-process of installation, guarantees installation distance and installation stability between the bus-bar pipe 1.
As shown in fig. 4, in order to ensure that the mounting portion 111 on the bus bar tube 1 can be quickly fixed after being inserted into the overlapping hole 3321, a clamping mechanism 4 for clamping the bus bar tube 1 may be disposed on the overlapping fixing seat 332, a cavity 3322 is disposed inside the overlapping fixing seat 332, and the cavity 3322 is located outside the overlapping hole 3321.
