Description

Technical Field

[0001] This application relates to the field of wind power generation technology, specifically a wind turbine controller. Background Technology

[0002] A wind turbine controller, also known as a wind power generation controller or wind energy charging controller, is an intelligent controller specifically designed for wind power generation systems. It can not only improve the efficiency of wind power generation, but also protect the safe operation of batteries and wind turbines. The nacelle is a common installation location for wind turbine controllers.

[0003] A search revealed a patent with publication number CN206498621U that discloses a wind turbine controller. The controller includes a controller housing, which comprises a protective shell, a radiator cover, and mounting strips. Several pairs of limiting magnetic strips are fixed side-by-side on opposite sides inside the controller housing. This invention protects the wind turbine controller by employing a floating, embedded protective shell to prevent current disturbances. The protective shell also ensures the stability of the controller within the controller housing. The magnetic ring, limiting magnetic strips, and supporting magnetic strips enable coordinated movement, preventing damage from external impacts.

[0004] The above solution has the following drawbacks in use: Although the wind turbine controller has a certain degree of protection, it is usually installed in the nacelle by bolt fasteners. This installation and disassembly is inefficient. When the controller needs to be disassembled for maintenance or replacement, the bolts need to be loosened one by one, which is cumbersome, time-consuming and labor-intensive. Utility Model Content

[0005] In view of this, the purpose of this utility model is to address the shortcomings of the prior art by proposing a wind turbine controller to solve the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides a wind turbine controller, including a nacelle top, a mounting platform fixedly installed at the bottom of the nacelle top, a columnar shaft detachably mounted on the mounting platform, a limiting mechanism for stabilizing the columnar shaft provided inside the mounting platform, a controller body fixedly mounted at the bottom of the columnar shaft, a connecting shaft fixedly connected to the top of the columnar shaft, a frustum cap fixedly connected to the top of the connecting shaft, a combined frustum slidably fitted on the outer surface of the connecting shaft, and an anti-accidental contact fastening mechanism provided at the bottom of the mounting platform.

[0007] Preferably, the limiting mechanism includes a sliding plate slidably connected to the inner wall of the mounting platform, and the number of sliding plates is set to two sets. The inner side of each set of sliding plates is fixedly provided with a pull rod. The controller body can be easily installed by simply lifting it upwards through the fastening mechanism, and it remains in a stable state without external influence.

[0008] Preferably, a pull button is fixedly connected to the end of the pull rod away from the mounting platform, and a spring is movably sleeved on the outer surface of the pull rod, with the two ends of the spring being fixedly connected to the outer surface of the slide plate and the inner wall of the mounting platform, respectively.

[0009] Preferably, a wedge-shaped positioning block is provided at the end of the pull rod away from the pull button, and the end of the wedge-shaped positioning block near the connecting shaft has a cut surface design.

[0010] Preferably, the anti-accidental contact fastening mechanism includes a lower connecting plate fixedly connected to the bottom of the mounting platform. The lower connecting plate is provided with a shape memory alloy arc plate. The anti-accidental contact fastening mechanism can improve the safety of the controller body after installation and prevent the controller body from falling and being damaged when accidentally touched (pushed upwards).

[0011] Preferably, a rubber toothed sleeve is provided on the outer surface of one end of the shape memory alloy arc plate, and a rubber toothed strip is provided on the outer surface of the end of the shape memory alloy arc plate away from the rubber toothed sleeve.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This wind turbine controller eliminates the tedious process of tightening and loosening bolts. The controller can be installed and disassembled simply by lifting it up and down. This design greatly shortens the installation and disassembly time and improves work efficiency. Especially in emergency repairs or regular maintenance, it can respond quickly, reduce downtime, and ensure the stable operation of the wind power station.

[0014] 2. The use of shape memory alloy arc plates and rubber toothed sleeves in this wind turbine controller further enhances the stability of the controller installation. The shape memory alloy's properties allow it to deform under external force and quickly return to its original shape once the external force is removed. This characteristic allows the arc plates to fit tightly against the columnar shaft, effectively resisting accidental lifting, preventing the controller from falling off accidentally, and improving the safety of the overall installation structure.

Detailed Implementation

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Please see Figure 1-5 A wind turbine controller includes a nacelle top 1, a mounting platform 2 fixedly installed at the bottom of the nacelle top 1, a columnar shaft 8 detachably installed on the mounting platform 2, a limiting mechanism for stabilizing the columnar shaft 8 provided inside the mounting platform 2, a controller body 9 fixedly installed at the bottom of the columnar shaft 8, a connecting shaft 10 fixedly connected to the top of the columnar shaft 8, a frustum cap 11 fixedly connected to the top of the connecting shaft 10, a combined frustum 12 slidably fitted on the outer surface of the connecting shaft 10, and an anti-accidental contact fastening mechanism provided at the bottom of the mounting platform 2. The size and shape of the frustum cap 11, the combined frustum 12, and the wedge-shaped positioning block 7 are pre-designed, and the specifications and parameters all have corresponding requirements.

[0023] Using the above technical solution, during the installation of the wind turbine controller on the nacelle roof 1, simply lift the controller body 9 upwards, allowing the truncated cone cap 11 along with the connecting shaft 10 to be inserted into the appropriate position within the mounting platform 2. Under the action of the limiting mechanism, the controller body 9 can be easily indirectly connected and installed to the nacelle roof 1 (e.g., ...). Figure 2 As shown), the anti-accidental contact fastening mechanism is designed to prevent the controller body 9 from falling off and being damaged when it is accidentally pushed upwards.

[0024] Specifically, the limiting mechanism includes a sliding plate 3 that is slidably connected to the inner wall of the mounting platform 2, and there are two sets of sliding plates 3. A pull rod 4 is fixedly inserted through the inner side of each set of sliding plates 3.

[0025] Through the above technical solution, during the process of pulling the lever 4 to drive the slide plate 3 to slide outward, the slide plate 3 will compress the spring 6 and cause it to deform (during which the spring 6 is in a compressed and energy-storing state).

[0026] Specifically, a pull button 5 is fixedly connected to the end of the pull rod 4 away from the mounting platform 2, and a spring 6 is movably sleeved on the outer surface of the pull rod 4, with the two ends of the spring 6 being fixedly connected to the outer surface of the slide plate 3 and the inner wall of the mounting platform 2, respectively.

[0027] With the above technical solution, under normal conditions (that is, when the pull button 5 is released), the elasticity of the spring 6 will push the slide plate 3 inward, and the two sets of wedge-shaped positioning blocks 7 will gradually move closer and can move into the vertical cavity of the mounting platform 2. Under normal installation of the controller body 9, it is not necessary to use the pull button 5. The pull button 5 is designed so that in the long-term use, some components may rust and become difficult to operate flexibly. Therefore, it is necessary to directly pull the pull button 5 to release the wedge-shaped positioning block 7 from limiting the round cap 11.

[0028] Specifically, a wedge-shaped positioning block 7 is provided at the end of the lever 4 away from the button 5, and the end of the wedge-shaped positioning block 7 near the connecting shaft 10 has a cut surface design.

[0029] Through the above technical solution, the cross-section design of the wedge positioning block 7 is designed to adapt to the truncated cone cap 11 and the combined truncated cone 12, wherein the inclined angles of the truncated cone cap 11 and the combined truncated cone 12 are the same, and the combined truncated cone 12 can be embedded into the truncated cone cap 11.

[0030] Specifically, the anti-accidental contact fastening mechanism includes a lower connecting plate 13 fixedly connected to the bottom of the mounting platform 2, and a shape memory alloy arc plate 14 is provided on the lower connecting plate 13.

[0031] Through the above technical solution, the shape memory alloy arc plate 14 is made of shape memory alloy material, which has excellent deformation and recovery ability (i.e., "shape memory effect").

[0032] Specifically, a rubber toothed sleeve 15 is provided on the outer surface of one end of the shape memory alloy arc plate 14, and a rubber toothed strip 16 is provided on the outer surface of the end of the shape memory alloy arc plate 14 away from the rubber toothed sleeve 15.

[0033] Through the above technical solution, the rubber rack 15 and the rubber sleeve 16 can be meshed and connected. As the rubber rack 15 is gradually inserted into the rubber sleeve 16, the shape memory alloy arc plate 14 will be sleeved on the outer surface of the cylindrical shaft 8, and its two ends will gradually approach (contract).

[0034] Working principle: During the installation of the wind turbine controller on the top of the nacelle 1, simply lift the controller body 9 upwards, allowing the truncated cone cap 11 along with the connecting shaft 10 to be inserted into the corresponding mounting platform 2. As the truncated cone cap 11 and connecting shaft 10 gradually move upwards into the mounting platform 2, the top of the truncated cone cap 11 will first contact the two sets of wedge-shaped positioning blocks 7. As the truncated cone cap 11 moves upwards, its inclined surface will contact the tangential surface of the wedge-shaped positioning blocks 7 and slide simultaneously. This pushes the wedge-shaped positioning blocks 7 through the truncated cone cap 11, causing them to push the pull rod 4 to gradually move outwards. This, combined with the compression of the spring 6 by the sliding plate 3, further contributes to the operation. During the compression of spring 6, the two sets of wedge-shaped positioning blocks 7 move away from each other. When the truncated cone cap 11 moves up to the height just past the wedge-shaped positioning blocks 7, the truncated cone cap 11 no longer holds and limits the two sets of wedge-shaped positioning blocks 7. Therefore, under the elastic restoring action of spring 6, it will push against the corresponding sliding plate 3, causing it to slide closer to each other along the inner wall of the mounting platform 2. That is, the two sets of wedge-shaped positioning blocks 7 will also move closer synchronously until the two sets of wedge-shaped positioning blocks 7 are at the bottom of the truncated cone cap 11, supporting it, thereby initially and indirectly installing the controller body 9 below (the state of the controller body 9 after installation and the state of the interior of the mounting platform 2 at this moment is as follows). Figure 2 and Figure 4As shown), the combination of the wedge-shaped positioning block 7 and the spring 6 forms an automatic locking mechanism. Once the controller body 9 is installed in place, the wedge-shaped positioning block 7 automatically locks under the action of the spring 6, effectively limiting the installation of the controller body 9. When it is necessary to remove the controller body 9, simply continue to lift the controller body 9 upwards. During this process, the combined frustum 12 will gradually approach the wedge-shaped positioning block 7, and the wedge-shaped positioning block 7 will slide along the upper inclined surface of the combined frustum 12. The combined frustum 12 pushes against the wedge-shaped positioning block 7 during its upward movement, meaning the two sets of wedge-shaped positioning blocks 7 move away from each other again. When the combined frustum 12 moves upwards to the middle maximum diameter part and passes the wedge-shaped positioning block 7, the two sets of wedge-shaped positioning blocks 7 will again press against the lower inclined surface of the combined frustum 12 under the elastic limiting action of the spring 6. Then, the controller body 9 is lowered. During this process, the two sets of wedge-shaped positioning blocks 7 can lift the combined frustum 12, allowing it to slide upwards along the connecting shaft 10 (while the connecting shaft 10 moves downwards), until... The combined frustum 12 is embedded into the hollowed-out area at the bottom of the frustum cap 11. At this time, the combined frustum 12 and the frustum cap 11 combine to form a new "combined frustum". Continuing to move downwards, the wedge-shaped positioning block 7 can directly pass over this new "combined frustum", thereby disengaging from the combined frustum 12 and the frustum cap 11. Finally, the cylindrical shaft 8 is disengaged from the mounting platform 2, making it easy to remove the generator controller. In order to avoid accidentally pushing the controller body 9 upwards and causing it to detach, after the controller body 9 is initially installed, the shape memory alloy arc plate 14 needs to be fitted onto the outer surface of the cylindrical shaft 8. At the same time, the rubber rack 16 is gradually inserted into the rubber rack 15. With the mutual meshing of the two, it will gradually tighten the shape memory alloy arc plate 14 until the shape memory alloy arc plate 14 completely and firmly wraps the cylindrical shaft 8. That is, the cylindrical shaft 8 is stably connected to the bottom of the mounting platform 2 through the lower connecting plate 13, which further improves the stability and safety of the controller body 9 installation.
