Description

Technical Field

[0001] This application relates to the technical field of seismic bracing, and in particular to a bidirectional seismic bracing for wind turbines. Background Technology

[0002] A two-way seismic brace for wind turbines is a specialized support device used to install and fix wind turbine equipment and provide two-way seismic protection. By providing constraint forces in two orthogonal dimensions in the horizontal plane, it limits the displacement of the wind turbine during an earthquake, preventing equipment damage or secondary safety accidents caused by shaking, collision, or falling of the wind turbine.

[0003] Currently, existing wind turbine supports typically weld the wind turbine to a fixed base, and operators then use expansion bolts to fix the fixed base to the building's load-bearing structure (such as concrete beams or steel frames).

[0004] When existing wind turbine supports are in use, the fixed base is prone to detaching from the building's load-bearing structure when subjected to impact forces from the external environment (such as earthquakes, pipeline resonance, etc.), making the wind turbine easy to fall to the ground and cause safety accidents. Utility Model Content

[0005] To prevent the wind turbine from falling to the ground, this application provides a bidirectional anti-seismic support for the wind turbine.

[0006] This application provides a bidirectional seismic-resistant support for wind turbines, which adopts the following technical solution: A bidirectional seismic-resistant support for a wind turbine includes a mounting plate, a wind turbine, a first auxiliary support assembly, and a second auxiliary support assembly. The mounting plate is horizontally positioned, and a mounting frame is fixedly mounted on its bottom. Two sets of mounting frames are provided, each located on one side of the mounting plate. A spring shock absorber is vertically mounted on each mounting frame, and the bottom end of the spring shock absorber is fixedly connected to the mounting frame. A connecting rod is fixedly mounted between the two sets of mounting frames. The wind turbine is horizontally positioned within the mounting frame, and a connecting plate is fixedly mounted on the wind turbine. Two sets of connecting plates are provided, each located on one side of the wind turbine, and the connecting plate is fixedly connected to the top end of the spring shock absorber. The first auxiliary support assembly is mounted on the mounting frame, and the second auxiliary support assembly is located on one side of the mounting frame. Both the first and second auxiliary support assemblies are used to assist in supporting the mounting frame.

[0007] By adopting the above technical solution, the spring shock absorber buffers the vibration load generated during the operation of the fan. When the fan is subjected to external impact forces such as earthquakes or pipeline resonance, the first auxiliary support component provides lateral constraint to the mounting frame in the horizontal plane, and the second auxiliary support component provides longitudinal constraint to the mounting frame in the horizontal plane. The two form a multi-directional support system, which enhances the connection stability between the mounting frame and the building's load-bearing structure, prevents the mounting frame from falling off due to impact forces, and thus makes it less likely for the fan to fall to the ground.

[0008] Optionally, the first auxiliary support assembly is provided in two sets, and corresponds one-to-one with the two sets of mounting brackets; the first auxiliary support assembly includes an adjustment part and a support part; there are two adjustment parts, which are respectively located on both sides of the mounting bracket, and the adjustment parts are used to adjust the position of the support part; there are two support parts, which correspond one-to-one with the two adjustment parts, and the support parts are used to assist in supporting the mounting bracket.

[0009] By adopting the above technical solution, when in use, the two sets of first auxiliary support components support the two sets of mounting frames respectively, so as to achieve symmetrical force on the mounting frames, making the mounting frames less prone to tilting. The adjustment part adjusts the position of the support part, making the support part easy to adapt to different installation scenarios.

[0010] Optionally, the adjusting part includes a first seismic base, a mounting bolt, a limiting plate, and a mounting nut; the mounting frame has guide sliding holes, and two sets of guide sliding holes are provided, with the two sets of guide sliding holes located on both sides of the mounting frame respectively; each set of guide sliding holes has multiple holes spaced apart along the vertical direction; the first seismic base is vertically disposed on one side of the mounting frame and is slidably connected to the mounting frame; the mounting bolt is inserted into one of the guide sliding holes and is threadedly connected to the first seismic base; the limiting plate is vertically disposed on the side of the first seismic base close to the mounting frame, the limiting plate is slidably connected to the mounting frame, and the mounting bolt is threadedly connected to the limiting plate; the mounting nut is located on the side of the limiting plate away from the mounting frame and is threadedly connected to the mounting bolt.

[0011] By adopting the above technical solution, during installation, the operator slides the first seismic base vertically to the designated position of the mounting frame, and at the same time places the limiting plate on one side of the first seismic base. The operator inserts the mounting bolt into the guide sliding hole and passes it through the first seismic base and the limiting plate in sequence. By screwing the mounting nut onto the mounting bolt, the first seismic base and the limiting plate can be easily clamped to the mounting frame.

[0012] Optionally, the support includes a support rod and a second seismic base; the support rod is inclined on one side of the mounting frame and rotatably connected to the first seismic base; the second seismic base is horizontally arranged and rotatably connected to the end of the support rod away from the first seismic base.

[0013] By adopting the above technical solution, during installation, the operator rotates the support rod onto the second seismic base, which is then fixed to the installation area with expansion bolts. After rotating the support rod to the specified angle, the operator rotates the first seismic base onto the support rod and simultaneously fixes it to the mounting frame with mounting bolts and nuts. The support rod decomposes the impact force along the length of the mounting frame into a component force along the length of the support rod, thus dispersing the local stress of the mounting frame and making it less prone to damage due to stress concentration.

[0014] Optionally, the second auxiliary support assembly includes a third seismic base, a support telescopic rod, and a fourth seismic base; the third seismic base is fixedly disposed at the bottom of the mounting frame; the support telescopic rod is inclined and its fixed end is rotatably connected to the third seismic base; the fourth seismic base is horizontally disposed and is rotatably connected to the movable end of the support telescopic rod.

[0015] By adopting the above technical solution, during installation, the operator fixes the fourth seismic base to the installation area with expansion bolts. When the mounting frame is subjected to an impact force in its own width direction, the supporting telescopic rod is decomposed into a component force along the length direction of the supporting telescopic rod, which disperses the local stress of the mounting frame and makes the mounting frame less prone to damage due to stress concentration.

[0016] Optionally, the second auxiliary support assembly is provided in two sets, and is located on both sides of the mounting frame respectively.

[0017] By adopting the above technical solution, when in use, the two sets of second auxiliary support components provide symmetrical support to the mounting frame from both sides of the bottom, balancing the force on both sides of the mounting frame and preventing the mounting frame from tilting or deforming due to uneven force on one side of the bottom.

[0018] Optionally, an adjustment assembly is provided on one side of the mounting bracket. The adjustment assembly is used to adjust the extension and retraction of the movable end of the support telescopic rod. The adjustment assembly includes an adjustment plate, a sliding block, and a locking part. The adjustment plate is horizontally disposed on one side of the mounting plate and is fixedly connected to the mounting plate. The adjustment plate has two sets of sliding grooves, each corresponding to one of the two sets of the second auxiliary support assemblies. The sliding block is horizontally disposed in the sliding groove and is slidably connected to the adjustment plate. The sliding block is fixedly connected to the fourth anti-seismic base. The locking part is located on the adjustment plate and is used to lock the sliding block.

[0019] By adopting the above technical solution, during installation, the operator drives the sliding block to slide along the length of the sliding groove, and at the same time drives the movable end of the support telescopic rod to extend and retract synchronously; when the sliding block slides to the designated position, the locking part locks the sliding block, and the third anti-seismic base is fixed to the mounting frame, making it difficult for the movable end of the support telescopic rod to extend and retract.

[0020] Optionally, the locking part includes a locking bolt and a locking nut; a locking hole is provided on one side of the adjusting plate, and the locking hole is connected to both sets of sliding grooves; the locking bolt is inserted into the locking hole and passes through the two sets of sliding blocks in sequence; the locking nut is vertically arranged on one side of the adjusting plate and is threadedly connected to the locking bolt.

[0021] By adopting the above technical solution, when the sliding block slides to the designated position, the operator inserts the locking bolt into the locking hole and passes it through the two sets of sliding blocks in sequence. The operator then tightens the locking nut to make the sliding block less likely to slide, thereby making it difficult for the movable end of the support telescopic rod to extend or retract.

[0022] In summary, this application includes at least one of the following beneficial technical effects: By setting up a first auxiliary support component and a second auxiliary support component, the mounting frame is less likely to wobble horizontally when subjected to impact forces from the external environment. By setting up adjustment components, the state of the second auxiliary support component can be easily adjusted. Attached Figure Description

The second seismic base 322 is horizontally positioned and rotatably connected to the end of the support rod 321 furthest from the first seismic base 311.

[0033] During installation, the operator fixes the second seismic base 322 to the installation area using expansion bolts. After the second seismic base 322 is installed, the operator rotates the support rod 321 to a specified angle until the first seismic base 311 is in contact with the side wall of the mounting frame 11. At the same time, the operator places the limiting plate 313 on one side of the first seismic base 311. The operator inserts the mounting bolt 312 into the guide sliding hole 112 and passes it through the first seismic base 311 and the limiting plate 313 in sequence. By screwing the mounting nut 314 onto the mounting bolt 312, the first seismic base 311 and the limiting plate 313 clamp the mounting frame 11.

When the sliding block 52 slides to the designated position, the operator inserts the locking bolt 531 into the locking hole 512 and passes it through the two sets of sliding blocks 52 in sequence. The operator then tightens the locking nut 532. At the same time, the operator extends the movable end of the support telescopic rod 42. When the third seismic base 41 abuts against the mounting frame 11, the operator installs the third seismic base 41 onto the mounting frame 11.

[0039] The implementation principle of a bidirectional seismic brace for a wind turbine according to an embodiment of this application is as follows: During installation, the operator installs the mounting plate 1 and the adjusting plate 51 into the installation area using expansion bolts, and simultaneously fixes the second seismic base 322 into the installation area using expansion bolts.

At the same time, the operator extends the movable end of the support telescopic rod 42 until the third seismic base 41 abuts against the mounting frame 11. The operator then fixes the third seismic base 41 to the mounting frame 11.
