Technical Field
[0001] This utility model relates to the field of wind power generation technology, specifically to a wind turbine pitch motor driver. Background Technology
[0002] As an important component of renewable energy, wind power generation is receiving increasing attention for its technological development. In wind turbine generator sets, the pitch system is one of the key components, responsible for adjusting the blade angle according to changes in wind speed to optimize energy capture efficiency and ensure the safe operation of the wind turbine. Therefore, it is particularly important to develop a wind turbine pitch motor drive to drive the wind turbine pitch motor.
[0003] A wind turbine pitch actuator, as described in reference announcement number CN220955908U, includes a base plate. A positioning mechanism is provided on the upper surface of the base plate, and an actuator body is housed within the positioning mechanism. A baffle is fixedly connected to one end of the upper surface of the base plate. The positioning mechanism includes a bidirectional screw shaft with first mounting blocks threaded to both ends. Positioning clamps are fixedly connected to the upper surfaces of the two sets of first mounting blocks, and a stabilizing plate is positioned directly above the positioning clamps. Through the cooperation between the positioning mechanism, the base plate, and the baffle, the actuator is limited by the baffle. A tool is used to rotate the bidirectional screw shaft, thereby causing the two sets of first mounting blocks to move relative to each other. This causes the two sets of positioning clamps to move closer together and tighten the actuator body, facilitating the installation of actuator bodies of different specifications and improving the stability of the actuator body installation. It also saves time and effort during assembly and disassembly. However, while this actuator can be well applied, when placed on a designated platform, it is not easy to adjust the position of the actuator body as needed, making it difficult to operate and use the actuator body from a designated area. This presents some inconvenience during use and requires further improvement. Utility Model Content
[0004] The purpose of this utility model is to provide a wind turbine pitch motor driver to solve the problem mentioned in the background art that although the driver can be applied well, when the driver is placed on a designated platform, it is not easy to adjust the position of the driver body as needed, and it is difficult to operate and use the driver body in a designated area, which causes certain inconvenience during use.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a wind turbine pitch motor driver, comprising a base plate, a rotary drive component mounted on one side of the top of the base plate, a threaded rod at one end of the rotary drive component, a threaded cylinder threadedly mounted on the outer wall of one side of the threaded rod, a connecting seat on the outer wall of one side of the threaded cylinder, a support platform on the outer wall of the connecting seat away from the threaded cylinder, a guide rod fixed to the inner side of the base plate below the support platform, the guide rod being movably connected to the support platform, a side U-shaped frame on one side of the top of the support platform, a driver body mounted on the top of the support platform on one side of the side U-shaped frame, positioning plates on both outer walls of the bottom of the driver body, a heat dissipation vent on one side of the outer wall of the driver body, two knobs on the outer wall of the driver body on the side of the heat dissipation vent, and a first positioning hole at each corner of the outer wall of the base plate.
[0006] Preferably, a limiting rail is provided on the inner wall of the base plate on the side of the support platform away from the connecting seat, and a rail seat is slidably connected on the outer wall of the limiting rail. The outer wall of the rail seat is connected to the bottom end of the support platform. The movement range of the support platform is limited by the setting of the rail seat and the limiting rail.
[0007] Preferably, the side U-shaped frame has a strip groove inside, and both ends of the strip groove extend to the outside of the side U-shaped frame. The strip groove is provided to limit the movement range of the nut pair.
[0008] Preferably, a helical rod is rotatably mounted on the bottom of the side U-shaped frame, and the top end of the helical rod extends to the outside of the side U-shaped frame and is equipped with a handle. By rotating the handle, the helical rod is driven to rotate.
[0009] Preferably, a nut pair is threaded onto the outer wall of the upper end of the screw rod. One end of the nut pair passes through a strip groove and is provided with an L-shaped pressure plate. The L-shaped pressure plate is used to press the driver body down to the top of the support platform.
[0010] Preferably, the positioning plate has waist-shaped holes on both sides inside, and both ends of the waist-shaped holes extend to the outside of the positioning plate. The waist-shaped holes are provided to facilitate bolting and positioning of the driver body.
[0011] Compared with the prior art, the beneficial effects of this utility model are: the wind turbine pitch motor driver not only improves the convenience of use, but also makes it easy to disassemble and maintain the driver body, and ensures the stability of the driver during use.
[0012] The threaded rod is rotated by a rotary drive component, causing the threaded cylinder to slide on the outer wall of the threaded rod. The threaded cylinder then drives the carrier platform to move horizontally via the connecting seat. At this time, the carrier platform slides on the outer wall of the guide rod, which allows the carrier platform to drive the driver body to move smoothly, thereby moving the driver body to the designated area for operation and use, thus improving the convenience of using the driver.
[0013] By rotating the handle, the screw rod is driven to rotate. After the movement range of the nut pair is limited by the slot, the nut pair slides on the outer wall of the screw rod and drives the L-shaped pressure plate to move up and down smoothly. When the L-shaped pressure plate moves down and presses against the top of the driver body, the driver body can be positioned on the top of the support platform. When the L-shaped pressure plate moves up and detaches from the top of the driver body, the driver body can be disassembled, thus achieving the purpose of easy disassembly and maintenance of the driver body.
[0014] By using bolts to pass through the waist-shaped hole and screw them into the top of the support platform, the driver body can be bolted and placed on the top of the support platform. When bolts are passed through the first positioning hole and screwed into the threaded groove reserved on the mounting platform, the base plate can be bolted and placed on the designated mounting platform. This can effectively reduce the displacement of the driver during use, thereby ensuring the stability of the driver during use. Attached Figure Description
