Technical Field

[0001] This utility model relates to the field of wind power generation technology, specifically a wind power generation grid-connected power supply control device. Background Technology

[0002] In wind power generation systems, grid-connected power supply control devices are the core equipment for achieving stable grid connection of wind power. They need to be installed inside the wind turbine tower and undertake key functions such as wind power regulation, grid adaptation, and fault protection.

[0003] The electrical components inside the existing wind power grid-connected power supply control cabinet are mostly fixed directly to the bracket inside the cabinet with bolts. After fixing, the position cannot be flexibly adjusted, which is not conducive to quick disassembly and maintenance in the later stage.

[0004] Moreover, control cabinets mostly use traditional iron cabinets, which have a certain structural strength but are heavy. The internal space of wind turbine towers is narrow and they need to be hoisted and installed at high altitudes. The excessive weight of the cabinets not only increases the load on the hoisting equipment, but also makes them prone to collision with the inner wall of the tower due to instability of the center of gravity during hoisting, causing damage to the cabinets or the tower.

[0005] Therefore, it is necessary to propose a wind power generation grid-connected power supply control device. Utility Model Content

[0006] The purpose of this invention is to provide a wind power generation grid-connected power supply control device to solve the problems mentioned in the background art.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-5 ;

[0028] A wind power generation grid-connected power supply control device includes a control cabinet 1. The control cabinet 1 serves as the main frame of the device, integrating and protecting the internal electrical components, preventing damage to the components from external dust and moisture, and providing an installation foundation for various functional components. This ensures the stable operation of grid-connected power supply control components, extends the service life of the equipment, and facilitates centralized management and maintenance. The control cabinet 1 is made of aerospace-grade aluminum alloy, which is 60% lighter than iron cabinets, with a shell thickness of 3mm, ensuring strength while reducing weight. The bottom of the control cabinet 1 has a cable inlet 14, which provides an access channel for external wind power cables, allowing the cables to be connected to the electrical components inside the control cabinet in an orderly manner, improving the standardization of wiring inside the cabinet, and facilitating future line maintenance.

[0029] The control cabinet 1 is equipped with an assembly mechanism 100, which facilitates the assembly of the wind power generation grid-connected power supply control into the tower. The assembly mechanism 100 includes a support component 2 and an assembly component 3. The support component 2 is located inside the control cabinet 1, and the assembly component 3 is located at the upper and lower ends of the control cabinet 1.

[0030] Furthermore, the support assembly 2 includes a support rail 21, locking holes 22, and a connecting module 23. The support rail 21 is bolted to the inside of the control cabinet 1 at both ends. The support rail 21 provides a sliding track for the connecting module 23 and also serves as a mounting carrier for internal components. The support rail 21 can be adjusted in its installation position according to component size and wiring requirements, improving the utilization of cabinet space and avoiding the problem of components being unable to be adjusted after fixing. The locking holes 22 are evenly spaced at the front end of the support rail 21. The locking holes 22 cooperate with the locking blocks 26 to provide multiple fixing points for the slide block 24, enabling multi-position locking of the slide block 24 on the support rail 21 and meeting the installation distance and position requirements of different components. The connecting module 23 is mounted on the support rail 21 and includes a slide block 24 and a groove 241. The slide block 24 is slidably mounted within the support rail 21. The top of the slide block 24 is used to support the sliding of internal components via screws. 4. Sliding and locking of the locking block 26 enable the adjustment and fixation of the component position. The sliding process of the slide block 24 is smooth and avoids jamming. The inner wall of the slide block 24 has a groove 241. The first connecting shaft 25 is fixedly installed inside the groove 241 to provide sliding guidance for the second connecting shaft 251 and restrict it to move only along the axial direction. The second connecting shaft 251 is slidably installed inside the other end of the first connecting shaft 25. The other end of the second connecting shaft 251 is equipped with a locking block 26, which is engaged in the corresponding locking hole 22. A spring 252 is sleeved on the outside of the second connecting shaft 251. The second connecting shaft 251 cooperates with the spring 252 to realize the automatic reset and quick locking of the locking block 26. At the same time, it is also more convenient to disassemble and assemble. The side wall of the locking block 26 has a guide groove 261. The inside of the groove 241 is also fixedly installed with a guide block 27. The guide block 27 is slidably installed in the guide groove 261 to prevent the locking block 26 from shifting during the extension and retraction process.

[0031] Furthermore, assembly component 3 includes a support base 31, a support rod 32, and a limiting wheel 33. The support base 31 is fixedly installed on both the top and bottom of the control cabinet 1, serving as the mounting base for the support rod 32. The support rod 32 is inserted into the support base 31 and fixed by bolts. A limiting wheel 33 is mounted on one end of the support rod 32. Adjusting the distance between the limiting wheel 33 and the control cabinet 1 allows the position of the limiting wheel to be adjusted according to the inner wall size of the tower, ensuring the limiting wheel fits tightly against the inner wall of the tower and adapts to towers of different diameters. This prevents the control cabinet 1 from swaying during lifting. A lifting ring 34 is also fixedly installed on the top of the control cabinet 1, adapting to the hoist inside the tower. This design facilitates high-altitude installation and is used for the overall hoisting of the control cabinet. The top of the control cabinet 1 has handle grooves 35 on both sides, with an anti-slip rubber layer inside for easy handling. The first guide rail 11 is fixedly installed on the inner side of the top of the control cabinet 1, and the second guide rail 12 is fixedly installed on the inner side of the bottom of the control cabinet 1. The first guide rail 11 and the second guide rail 12 guide the cabinet door 13 to slide laterally. Multiple cabinet doors 13 are slidably arranged between the first guide rail 11 and the second guide rail 12. The cabinet doors 13 are connected by hinges, which can achieve overall sliding opening. Compared with traditional single doors, it does not occupy extra space after opening and is more convenient to open in narrow spaces inside the tower.

[0032] The working principle of this utility model is as follows: The control cabinet 1, as the core carrier of the electrical components for wind power generation and grid-connected power supply control, is made of aerospace-grade aluminum alloy, which significantly reduces weight while ensuring structural strength, providing a closed protective space for the internal electrical components. At the same time, the inlet 14 at the bottom of the control cabinet 1 provides a dedicated access channel for external wind power cables, allowing the cables to be connected to the internal components in an orderly manner, avoiding contact failures caused by messy wiring, and facilitating later inspection and maintenance. The support rail 21 is fixed to the inside of the control cabinet 1 by bolts, and the evenly spaced locking holes 22 at the front end provide multiple fixing points for the slide 24. When the slide 24 slides along the support rail 21, it can drive the internal components installed at the top to adjust their position. When it slides to the target position, the spring 252 in the groove 241 pushes the second connecting shaft 251 to move axially along the first connecting shaft 25, so that the locking block 26 engages with the corresponding locking hole 22. After component positioning is completed, during disassembly, simply press the locking block 26 to compress the spring 252 to release the lock, enabling the component to be quickly removed from the control cabinet 1 and its position adjusted, improving the utilization rate of the cabinet space, making the electrical components inside the control cabinet 1 easy to disassemble and assemble, and facilitating subsequent maintenance. By adjusting the insertion length of the support rod 32, the end limit wheel 33 is made to fit tightly against the inner wall of the tower, preventing the control cabinet 1 from shaking during hoisting and lifting. The top hoisting ring 34 cooperates with the hoisting hoist inside the tower to realize the overall high-altitude hoisting of the device. The first guide rail 11 on the inner side of the top of the control cabinet 1 and the second guide rail 12 on the inner side of the bottom provide lateral sliding guides for multiple cabinet doors 13. The cabinet doors 13 are connected by hinges and can be opened as a whole along the guide rails, solving the problem of traditional single doors occupying extra space when opened in the narrow space of the tower, and making it easier for operators to quickly access the internal components for maintenance.

[0033] In summary, by using snap-fit ​​connection modules inside the wind power grid-connected power supply control cabinet, the position of components can be quickly adjusted according to component size and wiring requirements to meet the installation requirements of electrical components of different specifications, and the components can be quickly disassembled and removed from the control cabinet.
