Description

Technical Field

[0001] The utility model relates to the technical field of wind turbines, in particular to a collector ring support structure of a wind turbine. Background Art

[0002] With the continuous development of wind farms and the rapid development of the wind power industry, slip ring products are widely used in various harsh environments such as plateaus, Gobi, oceans, and humid and hot environments. Due to the high humidity and thin air, the maintainability requirements for slip rings have also been raised to a new level. Slip rings can be used in any electromechanical system that requires continuous rotation and needs to transmit power and signals from a fixed position to a rotating position. Slip rings can improve system performance, simplify system structure, and avoid twisting of wires during rotation.

[0003] However, the following problems still exist in actual use:

[0004] (1) The existing support structure is to lift the collector ring. If it is not fixed, the collector ring will be offset. The fixation is usually welded, which is cumbersome to disassemble and increases the workload.

[0005] (2) The existing support structure requires tools to adjust the position of the collector ring when installing it, and the collector ring is relatively load-bearing and is difficult to adjust. Utility Model Content

[0006] In response to the shortcomings of the existing technology, the utility model provides a wind turbine collector ring support structure, which can stably support and fix the collector ring and does not require tools to reduce the workload when disassembling. In addition, the position of the collector ring can be adjusted to increase the practicality of the device, thereby solving the problems raised in the background technology.

[0007] The utility model provides the following technical solutions: a wind turbine collector ring support structure, comprising a base plate, a first support block fixedly installed on the top of the base plate, a second support block slidably installed on the side of the first support block, a connecting plate fixedly installed on the top of the second support block, a first fixed block slidably installed on the side of the inner wall of the connecting plate, a stabilizing block movably installed on the side of the inner wall of the first fixed block, a threaded rod threadedly connected to the inner wall of the stabilizing block, a second fixed block fixedly installed on one end of the threaded rod, a third fixed block hinged on both sides of the second fixed block, and a splint movably connected to the side of the connecting plate.

[0008] Preferably, a slide groove is provided on the top of the base plate, and a pulley body is slidably installed on the side of the inner wall of the slide groove, and a third limit plate is fixedly installed on the top of the pulley body, and a first motor is fixedly installed on the top of the third limit plate, and a leather pulley is fixedly installed on the output end of the first motor, and the first limit plate is slidably installed on the top of the base plate, and a telescopic rod is fixedly installed on the top of the first limit plate, and a second limit plate is fixedly installed on the outer edge of the telescopic rod, and a threaded column is threadedly connected to the inner wall of the second limit plate, and a handle is fixedly installed on the outer edge of the threaded column, and a support shell is fixedly installed on the top of the telescopic rod, and a limit wheel is slidably installed on the side of the inner wall of the support shell.

[0009] Preferably, a clamping rod is movably engaged with the inner wall of the first support block, and an outer edge of the clamping rod is movably engaged with the inner wall of the second support block.

[0010] Preferably, a first rotating shaft is fixedly mounted on the side surface of the stabilizing block, and an outer edge of the first rotating shaft is movably connected to the inner wall of the first fixing block.

[0011] Preferably, a second rotating shaft is fixedly installed on the inner wall of the splint, one end of the second rotating shaft is fixedly connected to the side surface of the connecting plate, and the side surface of the third fixing block is fixedly connected to the side surface of the splint.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The wind turbine collector ring support structure rotates the threaded rod in the stabilizing block so that the first fixed block slides on the inner side of the connecting plate and cooperates with the first rotating shaft, the second fixed block and the third fixed block to apply pressure to the clamping plate. The second rotating shaft allows the clamping plate to adjust its angle to fix the collector ring, thereby solving the problem that the existing support structure lifts the collector ring, which will cause the collector ring to deviate if not fixed, and the fixation is welded, which is cumbersome to disassemble and increases the workload.

[0015] 2. The wind turbine collector ring support structure drives the threaded column to rotate by rotating the handle, thereby driving the second limit plate to adjust the height, and the second limit plate drives the telescopic rod to adjust the height, thereby driving the support shell to adjust. The limit wheel in the support shell can drive the collector ring for auxiliary support, and the operation of the first motor drives the leather pulley to rotate to rotate the collector ring, thereby solving the problem of existing support structures that when installing the collector ring, tools are needed to adjust the position, and the collector ring is relatively heavy-bearing and is more difficult to adjust.
