Description

Technical Field

[0001] This invention relates to the field of wind turbine technology, specifically to a support device for wind turbines that facilitates improved stability. Background Technology

[0002] A wind turbine is a clean energy device that converts wind energy into electrical energy. Its basic working principle is to use wind to drive the blades to rotate, which in turn drives the generator to generate electricity through a transmission system. A typical wind turbine mainly consists of three parts: the tower, the nacelle (containing core components such as the generator and gearbox), and the rotor blades. Among them, the tower, as a supporting structure, plays a crucial role in transmitting the gravity load, wind-induced load, and inertial torque of the entire nacelle and blades to the foundation. The stability and reliability of its connection with the foundation directly determine the safety and efficiency of the entire machine's operation. In the field of wind power technology, the installation stability of wind turbines is the fundamental guarantee for their long-term safe and efficient operation. At present, small and medium-sized wind turbines, especially those used for distributed power generation, communication base stations or power supply in remote areas, generally use prefabricated or cast-in-place cement bases as their basic support structure. However, in the existing installation method, the upper surface of the cement base is usually flat and lacks a pre-positioning structure that matches the bottom flange or base of the wind turbine tower. During the installation process, the construction workers need to hoist the heavy wind turbine tower above the base and then rely on visual observation and repeated trial and error to make fine adjustments to ensure that its central axis is precisely aligned with the theoretical center point of the base. This process is not only time-consuming and labor-intensive, increasing the difficulty and risk of high-altitude operations, but also makes it difficult to guarantee the alignment accuracy, which brings difficulties to the subsequent verticality correction and bolt tightening. Summary of the Invention

[0003] The purpose of this invention is to provide a support device for wind turbine generators that facilitates improved stability.

[0004] The objective of this invention is achieved through the following technical solution: a support device for a wind turbine generator that facilitates improved stability, comprising a cement base, a base fixed to the top of the cement base, a top plate detachably connected to the top of the base, and a wind turbine generator body mounted on the top plate; A position adjustment mechanism for automatically centering the wind turbine body is provided between the base and the top plate; The position adjustment mechanism includes a radial centering component disposed in the top plate and an adjustment component disposed in the base for driving the radial centering component to move. The adjustment assembly includes an adjustment cylinder rotatably disposed in the inner cavity of the base, and the top of the adjustment cylinder is provided with a plurality of V-shaped grooves that change continuously from low to high. The bottom of the inner cavity of the regulating cylinder is coaxially provided with a circular groove, and multiple arc-shaped triangular locking grooves communicating with it are provided on the side wall of the circular groove. An extrusion unit is fixedly installed inside the base. The extrusion unit contacts the surface of the V-groove and can be driven by the V-groove to move up and down to open the radial centering component. The base is also equipped with a drive unit for driving the adjusting cylinder to rotate around its axis.

[0005] The extrusion unit includes a bracket fixed inside the base, and a frustum-shaped top column is slidably connected vertically to the bracket; A connecting plate is fixed to the outside of the frustum-shaped top column, and a first elastic element providing downward restoring force is provided between the connecting plate and the base; The bottom of the connecting plate is fixed with a contact post that always keeps in contact with the surface of the V-shaped groove.

[0006] The drive unit includes an inner disk rotatably connected to the base via a rotating shaft, and the inner disk is located within the circular groove; One end of the rotating shaft extends to the outside of the base and is fixed with a turntable, which has multiple insertion holes. A one-way locking mechanism is provided between the inner disc and the adjusting cylinder.

[0007] The one-way locking mechanism includes a locking block that is slidably connected to the radial direction of the inner disk, and a second elastic element is provided between the locking block and the inner disk so that its end is always extended out of the inner cavity of the inner disk; The protruding end of the locking block engages with the inclined surface of the arc-shaped triangular locking groove, allowing the inner disc to drive the adjusting cylinder to rotate in only one direction.

[0008] The radial centering assembly includes a plurality of radial sliding grooves uniformly opened in the top plate along the circumference, and a connecting block is slidably connected in each sliding groove. A centering plate facing the center is connected to the top of the connecting block. A third elastic element providing an inward restoring force is provided between the connecting block and the inner end of the sliding groove; The top plate has a clearance hole in the center, and the frustum-shaped top column can pass through the clearance hole to rise and abut against the surface of all the centering plates, driving each of the centering plates to open radially synchronously.

[0009] When multiple centering plates are closed together, they form a complete guide ring. Each centering plate has a friction plate bonded to its outer working surface. The friction plate has anti-slip texture on its surface and is made of a high-friction coefficient and wear-resistant elastic material.

[0010] One end of the turntable is flush with or slightly lower than the upper surface of the cement base, and the depth of the insertion hole is greater than the diameter of the standard tool pin.

[0011] The centering process of the position adjustment mechanism is as follows: rotating the turntable drives the inner disk to rotate in one direction and drives the adjusting cylinder to rotate through the one-way locking mechanism. The high point of the V-shaped groove pushes the contact column and the frustum-shaped top column to rise. The frustum-shaped top column opens up each of the connecting blocks and the centering plate. The centering plate contacts and corrects the position of the wind turbine body.

[0012] Compared with the prior art, the advantages of the present invention are as follows: 1. This invention utilizes a built-in mechanical position adjustment mechanism. Operators only need to rotate the turntable on the ground to convert the rotational motion into the synchronous radial expansion of multiple centering plates through a series of defined mechanical transmissions (the turntable drives the inner plate, and the inner plate pushes the adjusting cylinder through the locking block). This process automatically guides and holds the wind turbine tower or base, quickly and automatically aligning its central axis with the center of the support device. This eliminates the need for repeated fine-tuning during hoisting, and the alignment accuracy is guaranteed by the mechanical structure, improving the first-time installation success rate and significantly shortening the installation time.

[0013] 2. This invention employs a step-locking design. The continuous V-groove on the adjusting cylinder, in conjunction with the extrusion unit, precisely converts the continuous rotation of the adjusting cylinder into a stepped lifting of the ejector column, thereby achieving graded opening of the centering plate. This design allows operators to make incremental fine adjustments based on the actual fit until the optimal clamping state is achieved. At the same time, the one-way locking mechanism ensures that the mechanism can self-lock at any adjustment position, effectively preventing accidental loosening of the centering state under wind load or vibration. This provides a continuous and stable radial constraint force for the wind turbine, enhancing the reliability of the foundation connection. Attached Figure Description

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figure 1-9 The diagram shows an embodiment of a support device for a wind turbine generator that facilitates improved stability, provided by the present invention. It includes a cement base 1, a base 101 fixedly disposed on the top of the cement base 1, a top plate 102 detachably connected to the top of the base 101, and a wind turbine generator body 103 mounted on the top plate 102. A position adjustment mechanism for automatically centering the wind turbine generator body 103 is provided between the base 101 and the top plate 102; The position adjustment mechanism includes a radial centering component disposed in the top plate 102, and an adjustment component disposed in the base 101 for driving the radial centering component to move. The adjustment assembly includes an adjustment cylinder 2 rotatably disposed in the inner cavity of the base 101, and the top of the adjustment cylinder 2 is provided with a plurality of V-shaped grooves 201 that change continuously from low to high. A circular groove 202 is coaxially provided at the bottom of the inner cavity of the regulating cylinder 2, and multiple arc-shaped triangular locking grooves 203 communicating with it are provided on the side wall of the circular groove 202. An extrusion unit is fixedly installed inside the base 101. The extrusion unit contacts the surface of the V-groove 201 and a radial centering component can be moved up and down by the V-groove 201 to open it. The base 101 is also equipped with a drive unit for driving the adjusting cylinder 2 to rotate around its axis; This solution establishes the basic framework and core mechanism of the device. Its beneficial effect lies in the fact that by setting a position adjustment mechanism integrated between the base 101 and the top plate 102, the rotational motion of the adjustment component (including the adjustment cylinder 2, V-shaped groove 201, circular groove 202, and arc-shaped triangular locking groove 203) is converted into vertical motion through the extrusion unit, which ultimately drives the radial centering component to move, thus realizing the automatic centering of the wind turbine body 103. This design solves the technical problem of low efficiency caused by repeated manual centering in traditional installation. The principle is that the drive unit drives the adjustment cylinder 2 to rotate, and the V-shaped groove 201 pushes the extrusion unit to rise and fall, thereby controlling the opening and closing of the centering component.

[0017] The extrusion unit includes a bracket 3 fixed in the base 101, and a frustum-shaped top column 301 is vertically slidably connected to the bracket 3; A connecting plate 302 is fixed to the outside of the frustum-shaped top column 301, and a first elastic element 303 providing downward reset force is provided between the connecting plate 302 and the base 101. The bottom of the connecting plate 302 is fixed with a contact post 304 that always maintains contact with the surface of the V-groove 201; This scheme specifically defines the structure of the extrusion unit. Its beneficial effect is to provide an efficient and reliable force conversion and transmission scheme. The bracket 3 provides a stable guiding foundation. The frustum-shaped top column 301 serves as the final execution output component. The connecting plate 302 rigidly connects the contact column 304 and the frustum-shaped top column 301 to ensure synchronous movement. The first elastic element 303 provides a constant downward reset force, so that the contact column 304 always adheres tightly to the surface of the V-groove 201, ensuring the accuracy of displacement control. When release is required, it drives the entire unit to reset. The principle is that the contact column 304 moves along the trajectory of the V-groove 201, and the connecting plate 302 drives the frustum-shaped top column 301 to make precise linear movements.

[0018] The drive unit includes an inner disk 401 rotatably connected to the base 101 via a rotating shaft 4, and the inner disk 401 is located in the circular groove 202; One end of the rotating shaft 4 extends to the outside of the base 101 and is fixed with a turntable 402. Multiple insertion holes 403 are provided on the turntable 402. A one-way locking mechanism is provided between the inner plate 401 and the adjusting cylinder 2; This solution clarifies the specific composition of the drive unit. Its beneficial effect is that it provides an interface for manual operation and establishes an initial torque transmission path. The rotating shaft 4 serves as the transmission hub, and the inner disk 401 fixed on it is located in the circular groove 202 of the adjusting cylinder 2, providing an interface for one-way locking. The turntable 402 and its socket 403 constitute a ground-operable interface. Operators can easily apply rotational torque by inserting tools into the socket 403, reducing the intensity of operation. The principle is that rotating the turntable 402 directly drives the inner disk 401 to rotate through the rotating shaft 4.

[0019] The one-way locking mechanism includes a locking block 5 that is slidably connected to the inner disk 401 in the radial direction. A second elastic element 501 is provided between the locking block 5 and the inner disk 401 so that its end is always extended out of the inner cavity of the inner disk 401. The protruding end of the locking block 5 engages with the inclined surface of the arc-shaped triangular locking groove 203, so that the inner plate 401 can only drive the adjusting cylinder 2 to rotate in one direction. This solution defines the key components of the one-way locking mechanism. Its beneficial effect is that it realizes the step-by-step one-way drive and position self-locking of the adjusting cylinder 2, which is the core of realizing graded adjustment. The locking block 5 is always extended under the support of the second elastic element 501. When the inner plate 401 rotates clockwise, its surface abuts against the plane of the arc-shaped triangular locking groove 203, pushing the adjusting cylinder 2 to rotate. When there is a reverse tendency or an external force attempts to rotate the adjusting cylinder 2 in the opposite direction, the locking block 5 is locked against the vertical surface (locking surface) of the arc-shaped triangular locking groove 203 to prevent backlash and ensure the mechanical stability of the centering state. Its principle is the ingenious application of the "ratchet and pawl" principle.

[0020] The radial centering assembly includes a plurality of radial sliding grooves 6 evenly opened in the top plate 102 along the circumference. A connecting block 601 is slidably connected in each sliding groove 6, and a centering plate 602 facing the center is connected to the top of the connecting block 601. A third elastic element 603 providing an inward restoring force is provided between the connecting block 601 and the inner end of the sliding groove 6; A clearance hole 604 is provided in the center of the top plate 102. The frustum-shaped top column 301 can pass through the clearance hole 604, rise and abut against the surface of all the centering plates 602, driving each centering plate 602 to open radially synchronously. This solution details the execution part of the radial centering component, which achieves uniform and synchronous radial centering action. Multiple sliding grooves 6 are evenly distributed circumferentially, ensuring the symmetry of force distribution. The connecting block 601 slides in the groove, converting linear motion into radial movement of the centering plate 602. The third elastic element 603 provides the centering plate 602 with a pre-tightening force for inward reset, keeping it closed in the non-working state, resulting in a compact structure. The clearance hole 604 provides a channel for the rise of the frustum-shaped top column 301. The principle is that the conical surface of the rising frustum-shaped top column 301 simultaneously pushes the inner side of all connecting blocks 601, overcoming the elastic force of the third elastic element 603, so that all centering plates 602 open outward synchronously and smoothly.

[0021] When multiple centering plates 602 are closed together, they form a complete guide ring. Friction plates 7 are bonded to the outer working surface of each centering plate 602. The surface of the friction plates 7 is provided with anti-slip texture. The friction plates 7 are made of elastic material with high friction coefficient and wear resistance. This solution further optimizes the centering contact surface, which significantly enhances the friction and protection during centering. Multiple centering plates 602 form a complete guide ring, which can form a continuous and uniform annular contact with the inner wall of the wind turbine tower, resulting in a balanced distribution of correction force. The friction plate 7 and its anti-slip texture can effectively increase static friction and prevent the wind turbine from slipping slightly after centering or under wind load. The high friction coefficient and wear-resistant elastic material (such as engineering rubber) used can protect the wind turbine tower coating from scratches and adapt to slight non-roundness, ensuring a reliable grip.

[0022] One end of the turntable 402 is flush with or slightly lower than the upper surface of the cement base 1, and the depth of the insertion hole 403 is greater than the diameter of the standard tool pin. This solution specifies the installation details of the operating interface. Its beneficial effects are to ensure the ease of operation and environmental adaptability of the device. It requires that the upper surface of the turntable 402 be flush with or slightly lower than the upper surface of the cement base 1 to prevent it from protruding from the ground and being damaged by accidental collisions. It also facilitates site leveling. The depth of the insertion hole 403 is greater than the diameter of the standard tool pin, ensuring that the operating tools (such as pry bars) can be inserted to a sufficient depth to withstand the large torque, preventing slippage during operation, and improving the safety and convenience of operation.

[0023] The centering process of the position adjustment mechanism is as follows: the rotating turntable 402 drives the inner plate 401 to rotate in one direction and drives the adjusting cylinder 2 to rotate through the one-way locking mechanism. The high point of the V-groove 201 pushes the contact column 304 and the frustum-shaped top column 301 to rise. The frustum-shaped top column 301 opens up each connecting block 601 and the centering plate 602. The centering plate 602 contacts and corrects the position of the wind turbine generator body 103.

[0024] The core working principle of the technical solution of the present invention is to realize the centering and stable support of the wind turbine during installation by using an integrated mechanical transmission and execution mechanism with step locking function. In specific implementation, the cement base 1 is first firmly embedded in the soil of the installation site as the permanent foundation of the entire device. When installing the cement base 1, it is necessary to ensure that the upper surface of the base 101 fixed on its top and the turntable 402 located between the base 101 and the cement base 1 is exposed above the ground to ensure subsequent operability and maintainability. The specific working principle and adjustment process are as follows: In the initial state, the lowest point of the V-shaped groove 201 at the top of the adjusting cylinder 2 is in contact with the contact post 304 of the extrusion unit, the frustum-shaped top post 301 is in a low position, and each centering plate 602 of the radial centering assembly is in a contracted state under the action of the third elastic element 603. When it is necessary to install or calibrate the wind turbine generator body 103, the operator uses a tool to insert into the socket 403 on the turntable 402 exposed on the ground and rotates it in a set direction (e.g., clockwise). The rotating turntable 402 drives the inner plate 401 to rotate synchronously through the rotating shaft 4. The inner plate 401 is radially slidably connected to a locking block 5. Under the action of the second elastic element 501, the end of the locking block 5 normally extends out of the edge of the inner plate 401. When the inner plate 401 rotates clockwise, the surface of the locking block 5 will contact the plane of the arc-shaped triangular locking groove 203 on the side wall of the inner circular groove 202 of the regulating cylinder 2, thereby pushing the regulating cylinder 2 to rotate together. The rotation of the adjusting cylinder 2 causes the V-shaped groove 201 at its top to shift relative to the fixed contact post 304. The contact post 304 moves from the low point area of ​​the V-shaped groove 201 to the high point area, thus being lifted up. The contact post 304 is fixed to the frustum-shaped top post 301 through the connecting plate 302. Therefore, the frustum-shaped top post 301 rises accordingly. During this process, the specific contour design of the V-shaped groove 201 allows the bottom of the groove to temporarily lock the position of the contact post 304, preventing it from easily sliding back under the restoring force of the first elastic element 303, thereby stabilizing the frustum-shaped top post 301 at the current lifting height. The frustum-shaped top column 301 passes upward through the clearance hole 604 in the center of the top plate 102. The frustum-shaped inclined surface at its top abuts against and pushes outward the inner surface of all the centering plates 602. The centering plates 602 are slidably connected to the radial sliding groove 6 of the top plate 102 through the connecting block 601, thereby overcoming the elastic force of the third elastic element 603, so that multiple centering plates 602 open outward in the radial direction in sync, forming a ring-shaped centering plate 602. A friction plate 7 with anti-slip texture is bonded to its outer side, thereby contacting and holding the inner wall of the tower or base of the wind turbine body 103, and achieving preliminary centering correction. If more precise fine-tuning or further increase in centering and clamping force is required, step-by-step adjustment is necessary: ​​The operator first rotates the turntable 402 in the opposite direction (counterclockwise). This rotation causes the inner disc 401 to rotate in the opposite direction. Since the end of the locking block 5 is stuck in the arc-shaped triangular locking groove 203 at this time, the reverse rotation will cause the arc surface of the arc-shaped triangular locking groove 203 to press against the end face of the locking block 5, forcing the locking block 5 to overcome the elastic force of the second elastic element 501 and retract into the inner cavity of the inner disc 401, thereby disengaging from the current arc-shaped triangular locking groove 203. Continue rotating until the locking block 5 reaches the... Under the action of the two elastic elements 501, the block pops out again and falls into the next adjacent arc-shaped triangular locking groove 203. At this time, the turntable 402 is rotated clockwise again, and the surface of the locking block 5 will contact the surface of the new arc-shaped triangular locking groove 203, thereby driving the adjusting cylinder 2 to rotate a small angle again. This will move the contact post 304 from the bottom position of the currently locked V-shaped groove 201 to the next higher bottom position, realizing another lifting of the frustum-shaped top post 301, thereby pushing the centering plate 602 to open further radially, achieving a more precise centering and clamping effect. The entire adjustment process can repeat the above step operation to achieve precise control at different levels. The one-way locking mechanism (the cooperation between the locking block 5 and the arc-shaped triangular locking groove 203) ensures that the adjusting cylinder 2 will not rotate in the opposite direction due to external force when it is in the centering and clamping state, thus ensuring the stability of the support. When it needs to be disassembled after installation, the adjusting cylinder 2 can be completely rotated in the opposite direction to the initial position. All components will return to their original state under the reset action of the first elastic element 303 and the third elastic element 603. This device, through pure mechanical linkage and step locking design, combined with reliable foundation installation, realizes efficient, reliable, stable and precisely controllable automatic centering support for wind turbines.
