Description

Technical Field

[0001] The present invention relates to the technical field of wind turbines, and in particular to a stable bracket for wind turbines. Background Art

[0002] Wind power generation generally uses a tower to support the rotating blades. Wind power generation equipment is generally installed in open areas or on mountain tops. In order to ensure that the tower can stably support the rotating blades and other devices, a stable bracket will be installed under the tower to make the tower more stable.

[0003] There are only two types of stable brackets currently in use. One type has a fixed support rod length that cannot be adjusted, which is more limited in use. The other type has a threaded rod with adjustable length. When the support rod of this type of stable bracket is in use, due to the action of wind, the threaded connection part of the support rod will be under stress for a long time, which can easily cause the thread mouth to be misaligned, resulting in inconvenience in subsequent adjustment. Therefore, there is an urgent need to propose a stable bracket with a stable support rod structure. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a stable bracket for a wind turbine.

[0005] The technical solutions of the present invention are as follows:

[0006] A stabilizing bracket for a wind turbine, comprising a plurality of circumferentially evenly distributed supporting assemblies, each of the supporting assemblies mainly consisting of a clamp body, a supporting rod and an embedded portion; the clamp body is hinged to the top end of the supporting rod and is used to connect to the wind turbine tower; the supporting rod is a threaded telescopic rod consisting of two sections of a rod body, the two sections of the supporting rod are respectively provided with a fixing ring, and the two fixing rings are correspondingly provided with a plurality of fixing holes, and an auxiliary fixing rod is respectively passed through each group of corresponding fixing holes on the two fixing rings, and the two ends of the auxiliary fixing rod are respectively provided with threads and locked by nuts; the embedded portion is connected to the bottom end of the supporting rod by bolts and is used to be fixed to the ground.

[0007] The working principle of the above technical solution is as follows:

[0008] The present invention arranges multiple sets of auxiliary fixing rods between the two sections of the traditional threaded telescopic support rod. After the support rod is adjusted to an appropriate length, the fixing holes of the fixing rings on the two sections of the support rod are aligned, and the auxiliary fixing rods are inserted for auxiliary fixation. The auxiliary fixing rods can help the threaded part of the support rod withstand the lateral stress load of the support rod, avoiding the threaded part of the support rod from being subjected to lateral stress for a long time and causing thread misalignment, which leads to inconvenience in subsequent adjustment.

[0009] In a further technical solution, the arc-shaped structure has a central angle less than 90 degrees, and the back of the clamp body is integrally formed with a slot for clamping a clamping plate, and the clamping plate is hinged to the top end of the support rod; the clamping plate and the slot are correspondingly provided with screw holes for bolt fixing.

[0010] The card plate is limited by the slot and then locked and fixed by bolts to ensure a stable connection between the support rod and the clamp body. At the same time, the split structure of the card plate and the clamp body slot makes it easier to assemble and disassemble, improving construction efficiency.

[0011] In a further technical solution, one side of the clamp body is provided with a protruding edge, and the other side is provided with a step matching the protruding edge. When connecting the wind turbine tower, the protruding edges and steps on each clamp body are pressed and limited in sequence. A connecting plate is provided on the clamp body, and the connection and fixation between the clamp bodies are completed by passing bolts through the connecting plates on the two adjacent clamp bodies and tightening them with nuts, which can improve the overall fixing stability of the clamp.

[0012] In a further technical solution, the top end of the support rod is curved in an arc shape.

[0013] In a further technical solution, the embedded part is an inverted cone structure, the top of the embedded part is provided with a connecting rod for connecting the bottom end of the support rod, and the bottom of the embedded part is provided with an anti-dropout bottom plate, so that the embedded part can be firmly buried underground to prevent it from dropping out after long-term use.

[0014] The beneficial effects of the present invention are:

[0015] 1. The present invention sets multiple sets of auxiliary fixing rods between the two rod sections of the traditional threaded telescopic support rod, which can help the threaded portion of the support rod withstand the lateral stress load of the support rod, avoiding the threaded portion of the support rod being subjected to lateral stress for a long time and causing thread misalignment, which leads to inconvenience in subsequent adjustment;

[0016] 2. The connection between the support rod and the hoop body of the present invention is limited by the clamping plate through the clamping groove, and then locked and fixed by bolts, which can ensure a stable connection between the support rod and the hoop body. At the same time, the split structure of the clamping plate and the clamping groove of the hoop body is adopted, which is more convenient for assembly and disassembly, improving construction efficiency.

[0017] 3. The protruding edges and steps on each clamp body of the present invention are pressed and limited in sequence, which can improve the fixing stability of the clamp as a whole;

[0018] 4. The embedded part of the present invention has an inverted cone-shaped structure and an anti-dropout bottom plate is provided at the bottom, so that the embedded part can be firmly buried in the ground to prevent it from dropping out after long-term use. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0027] Example:

[0028] A stable support for a wind turbine, such as Figure 1 and Figure 5 As shown, the stable bracket includes several support components evenly distributed in the circumference, each support component mainly consisting of a clamp body 10, a support rod 20 and an embedded part 30; the clamp body 10 is hinged to the top end of the support rod 20 for connecting to the wind turbine tower 40; the support rod 20 is a threaded telescopic rod composed of two sections of rod bodies (the end of one section of the rod body has an external thread, the end of the other section of the rod body is hollow and has an internal thread, and the internal and external threads of the two sections of the rod body match, and the length of the support rod 20 can be adjusted by unscrewing or screwing in), and a fixing ring 21 is respectively provided on the two sections of the rod body of the support rod 20, and a number of fixing holes are correspondingly provided on the two fixing rings 21. An auxiliary fixing rod 22 is respectively passed through each group of corresponding fixing holes on the two fixing rings 21, and the two ends of the auxiliary fixing rod 22 are respectively provided with threads and locked by nuts; the embedded part 30 is connected to the bottom end of the support rod 20 by bolts for fixing to the ground.

[0029] The present invention sets multiple sets of auxiliary fixing rods 22 between the two sections of the traditional threaded telescopic support rod 20. After the support rod 20 is adjusted to an appropriate length, the fixing holes of the fixing rings 21 on the two sections of the support rod 20 are aligned, and the auxiliary fixing rods 22 are inserted for auxiliary fixation. The auxiliary fixing rods 22 can help the threaded part of the support rod 20 to withstand the lateral stress load of the support rod 20, thereby avoiding the threaded part of the support rod 20 from being subjected to lateral stress for a long time and causing thread misalignment, which leads to inconvenience in subsequent adjustment.

[0030] It should be noted that: since the adjustment accuracy of the length of the support rod 20 is not required to be high during use, the additional fine-tuning of the support rod 20 when aligning the fixing hole does not affect the normal use of the support rod 20. Generally, three sets of auxiliary fixing rods 22 are set, and the fine-tuning distance is only within one-third of the pitch.

[0031] In another embodiment, Figure 3 and Figure 4 As shown, it is an arc-shaped structure with a central angle less than 90 degrees. The back of the hoop body 10 is integrally formed with a slot 11 for clamping the clamping plate 12, and the clamping plate 12 is hinged to the top end of the support rod 20; screw holes 13 are correspondingly provided on the clamping plate 12 and the slot 11 for bolt fixing.

[0032] The clamping plate 12 is limited by the clamping slot 11 and then locked and fixed by bolts to ensure a stable connection between the support rod 20 and the clamping hoop body 10. At the same time, the split structure of the clamping plate 12 and the clamping slot 11 of the clamping hoop body 10 is adopted, which is more convenient for assembly and disassembly, and improves construction efficiency.

[0033] In another embodiment, Figure 3 and Figure 4 As shown, one side of the clamp body 10 is provided with a protruding edge 14, and the other side is provided with a step 15 matching the protruding edge 14. When connecting the wind turbine tower 40, the protruding edge 14 and the step 15 on each clamp body 10 are pressed and limited in sequence. A connecting piece 16 is provided on the clamp body 10. The connection and fixation between the clamp bodies 10 are completed by passing a bolt through the connecting piece 16 on the two adjacent clamp bodies 10 and tightening it with a nut, which can improve the overall fixing stability of the clamp.

[0034] In another embodiment, Figure 1 As shown, the top end of the support rod 20 is curved.

[0035] In another embodiment, Figure 2 As shown, the embedded part 30 is an inverted cone structure. The top of the embedded part 30 is provided with a connecting rod 31 for connecting to the bottom end of the support rod 20, and the bottom of the embedded part 30 is provided with an anti-dropout bottom plate 32, which facilitates the embedded part 30 to be firmly buried underground to prevent it from being dropped out after long-term use.

[0036] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
