Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine generator sets, in particular to a contactor for a yaw system of a wind turbine generator set. Background Art

[0002] A wind turbine, also known as a wind power generator, is a complete set of equipment and systems that convert wind energy into electricity. It includes not only the generator itself but also other auxiliary equipment, such as the tower, blades, pitch system, transmission system, and electronic control system. When wind blows over the windmill blades, the aerodynamic force causes them to rotate. This rotational force is converted into mechanical energy through the transmission system, and then the generator uses the principle of electromagnetic induction to convert this mechanical energy into electrical energy.

[0003] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when a wind turbine is in use, a yaw system is set up in the turbine. The contactor is an important component in the yaw system, and multiple contactors are also needed. Since most contactors need to be installed one by one, this is prone to operational inconveniences during operation; therefore, a wind turbine yaw system contactor is proposed to address the above problems. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a wind turbine yaw system contactor described in the present invention includes multiple controllers and fixing devices, and the surfaces of multiple controllers are provided with fixing devices, and the fixing devices include a placement plate, and the placement plate is sleeved on the surface of the controller, and the bottom end of the placement plate is fixedly connected to four support blocks, and bolts are inserted into the inner walls of the four support blocks. Both sides of the controller are fixedly connected to limit blocks, and two of the limit blocks are inserted into the inner wall of the placement plate. Insert blocks are inserted into the inner walls of the placement plate and the support block. Push the insert block to allow the insert block to be inserted into the inner wall of the placement plate and the limit block, and then fit the support block onto the installation component, and then rotate the bolt to the support block and the inner wall of the installation component. By setting the placement plate, support block, limit block and insert block, multiple controllers can be conveniently fixed at the same time, reducing the complexity of operation.

[0006] Preferably, two limiting grooves are provided on the surface of the placement plate, and the inner wall of the limiting groove of the placement plate is slidably connected to the surface of the limiting block. When the limiting block slides, the limiting block slides on the inner wall of the limiting groove of the placement plate, and the limiting groove is opened to accommodate the limiting block.

[0007] Preferably, a moving block is slidably connected to the inner wall of the placement plate near the insertion block, and the inner wall of the moving block is slidably connected to the surface of the insertion block. When the moving block slides, it will drive the insertion block to slide on the inner wall of the placement plate. The setting of the moving block can facilitate the adjustment of the position of the insertion block.

[0008] Preferably, a plurality of insertion holes are provided on the surface of the placement plate, and the insertion blocks are inserted into the inner walls of the insertion holes of the placement plate. When the insertion blocks slide, the insertion blocks are inserted into the inner walls of the insertion holes, and the opening of the insertion holes can accommodate the insertion blocks.

[0009] Preferably, the bottom end of the plug block is fixedly connected to a connecting block, and two springs are fixedly connected to the upper surface of the connecting block and the bottom end of the movable block. When the connecting block is released, the springs will rebound, and the springs drive the connecting block and the plug block to slide. By setting the springs, the connecting block and the plug block can be driven to slide and the position of the plug block can be limited at the same time.

[0010] Preferably, a filling device is provided at the bottom ends of the two support blocks close to each other, and the filling device includes a filling pad. The filling pad is located directly below the two support blocks, and elastic bands are fixedly connected to both sides of the filling pad. The side walls of the support blocks are fixedly connected to clips, and the elastic bands are sleeved on the surface of the clips. When the support blocks move, the filling pads will be squeezed on the mounting components. By providing the filling pads, the gap between the support blocks and the mounting components can be reduced.

[0011] Preferably, two blocks are fixedly connected to the surface of the filling pad, and a storage block is fixedly connected to the side wall of the support block near the block. The block is inserted into the inner wall of the storage block. The position of the filling pad can be limited by setting the block and the storage block.

[0012] The utility model is beneficial in that:

[0013] 1. When the utility model needs to install and fix multiple controllers, push the controller to drive the limit block to slide, the limit block is inserted into the inner wall of the limit groove of the placement plate, and then push the connecting block to drive the connecting block to slide, and the plug-in block slides on the inner wall of the moving block. When the connecting block slides, it will also drive the spring to contract, and then push the moving block to drive the moving block to slide. After the moving block slides to the appropriate position, release the connecting block spring to rebound, and the spring drives the connecting block and the plug-in block to slide, and the plug-in block is inserted into the inner wall of the socket hole of the placement plate and the inner wall of the limit block, and then the support block on the placement plate is fitted onto the installation component, and then the bolt is rotated into the support block and the inside of the installation component. By setting the entire device, the controller can be easily installed and fixed, and the cumbersomeness of installation and disassembly can be reduced, thereby facilitating maintenance and replacement of the controller.

[0014] 2. When the support block needs to be fixed, the utility model pushes the filling pad to allow the filling pad to drive the elastic belt and the stopper to slide. The filling pad fits the support block, the stopper is inserted into the inner wall of the storage block, and then the elastic belt is pulled to stretch the elastic belt, and then the elastic belt is put on the surface of the card strip. When the support block moves, the filling pad will be squeezed on the surface of the mounting component. By setting up the entire device, the wear and gap between the support block and the mounting component can be reduced, thereby increasing the stability of the installation.
