Description

Technical Field

[0001] This utility model relates to the field of pitch control cabinet technology, and in particular to a pitch control cabinet installation structure with sliding adjustment function. Background Technology

[0002] The pitch control unit is a key device in wind turbine generator sets used to control the blade pitch angle. It achieves precise adjustment of the blade angle through internal electrical components, which directly affects the wind capture efficiency and operational safety of the wind turbine.

[0003] Traditional pitch control units typically employ a fixed installation structure, with the installation position pre-set and non-adjustable. This makes it difficult to quickly adapt to different installation requirements when the wind turbine nacelle space is limited or there is installation interference with other equipment. Repeated adjustments to the nacelle structure or cabinet design are required, increasing installation complexity and time costs. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pitch control unit installation structure with sliding adjustment function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pitch control cabinet installation structure with sliding adjustment function includes a cabinet body. A support frame is fixedly connected to the bottom of the cabinet body. Two fixed frames are fixedly connected to the front and rear sides of the support frame. A sliding groove is opened on the side of each fixed frame away from the support frame. A sliding block is slidably arranged in each sliding groove. A sliding plate is fixedly connected to the side of each sliding block away from the sliding groove. A second mounting bracket is fixedly connected to one side of each sliding plate.

[0007] As a further improvement of this utility model, each of the fixed frames is provided with multiple threaded grooves on the upper and lower sides of the sliding groove, and bolts are provided at the four corners of one side of the sliding plate. Each bolt passes through the sliding plate and is screwed into the corresponding threaded groove.

[0008] As a further improvement of this utility model, two first mounting brackets are fixedly connected to both the left and right sides of the support frame, and a second fixing block is also connected between each first mounting bracket and the support frame.

[0009] As a further improvement of this utility model, each of the second mounting brackets has a first fixing block fixedly connected to both sides, and each of the first fixing blocks is fixedly connected to the corresponding sliding plate.

[0010] As a further improvement of this utility model, a connection port is provided on one side of the cabinet, and a connecting rod is fixedly connected to each of the four corners of the connection port on the cabinet.

[0011] As a further improvement of this utility model, the sliding block has a T-shaped structure, and the size of the sliding groove matches the size of the sliding block.

[0012] The beneficial effects of this utility model are:

[0013] By using the directional sliding cooperation of the sliding groove and the sliding block, combined with the locking structure of multiple threaded grooves and bolts, the position of the second mounting bracket is adjustable, which can flexibly adapt to the needs of different installation scenarios. The coordinated connection between the first fixing block and the second mounting bracket enhances the installation stability and avoids the problem of uneven force caused by adjustment. The lateral fixing design of the first mounting bracket and the second fixing block further improves the overall installation reliability of the cabinet and solves the technical problems of fixed installation position and inconvenient adjustment of traditional pitch control cabinets.

[0014] This invention achieves the beneficial effects of adjustable position and stable and reliable installation through the cooperation of sliding groove and sliding block and the locking of threaded groove and bolt. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Figures 1-3A pitch control cabinet installation structure with sliding adjustment function includes a cabinet body 1. A connection port 2 is provided on one side of the cabinet body 1 for docking and installation with other equipment. Connecting rods 3 are fixedly connected to the four corners of the connection port 2 on the cabinet body 1, securing the connection points between the cabinet body 1 and the external structure. A support frame 5 is fixedly connected to the bottom of the cabinet body 1, bearing the overall weight of the cabinet body 1 and providing bottom support. Two first mounting brackets 4 are fixedly connected to the left and right sides of the support frame 5, cooperating with the support frame 5 to achieve lateral fixation of the cabinet body 1. A second fixing block 14 is also connected between each first mounting bracket 4 and the support frame 5, enhancing the connection stability between the first mounting bracket 4 and the support frame 5. Two fixing frames 6 are fixedly connected to the front and rear sides of the support frame 5. A sliding groove 7 is provided on the side of each fixing frame 6 away from the support frame 5, and a sliding block 10 with a T-shaped structure is slidably installed in each sliding groove 7. The internal size of the sliding groove 7 matches the size of the sliding block 10. Each sliding block 10 has a sliding plate 8 fixedly connected to the side away from the sliding groove 7. Each sliding plate 8 can move under the sliding action of the sliding block 10 to change different installation positions. Each fixed frame 6 has multiple threaded grooves 11 sequentially opened on the upper and lower sides of the sliding groove 7. Each of the four corners of one side of the sliding plate 8 has a bolt 12. Each bolt 12 passes through the sliding plate 8 and is screwed into the corresponding threaded groove 11. The threaded groove 11 is used to lock the position of the sliding plate 8 in conjunction with the bolt 12. Each side of each sliding plate 8 is fixedly connected to a second mounting bracket 9. The second mounting bracket 9 is used to realize the adjustable connection between the cabinet 1 and other equipment. Each side of each second mounting bracket 9 is fixedly connected to a first fixing block 13. The first fixing block 13 is used to enhance the connection strength between the second mounting bracket 9 and the sliding plate 8. Each first fixing block 13 is fixedly connected to its corresponding sliding plate 8. The first fixing block 13 and the second mounting bracket 9 work together to achieve a uniform distribution of installation force.

[0021] When using this utility model, the cabinet 1 is first placed stably in the installation position by the support frame 5. Then, according to the installation requirements, the sliding plates 8 in the four fixed frames 6 on the front and rear sides of the support frame 5 are pushed so that the four sliding blocks 10 slide along the sliding groove 7, thereby driving the second mounting bracket 9 on the sliding plate 8 to be adjusted to the target position. At this time, the position of the second mounting bracket 9 is locked by screwing multiple bolts 12 into the multiple threaded grooves 11 on the upper and lower sides of the fixed frame 6 respectively. After the position is determined, the cabinet 1 is connected to the external structure by the four connecting rods 3 at the four corners of the cabinet 1 connection port 2.
