Description

Technical Field

[0001] This utility model relates to the field of support structure technology for wind turbine generator sets, and in particular to a support base for mounting a tower and a wind turbine generator set. Background Technology

[0002] Wind energy is a clean energy source that can reduce dependence on fossil fuels, and wind power generation has received increasing attention in recent years. Wind energy can be captured by wind turbines, which convert the kinetic energy of the wind into mechanical energy, and then into electrical energy. Traditional wind turbines are generally built in areas with abundant wind resources. However, due to the possibility of severe weather in some areas, such as strong winds, a base is usually installed on the ground to ensure the stable operation of the wind turbine. The turbine's casing is then mounted on the base to maintain stability. However, existing bases are manufactured as a single piece or welded to the tower, resulting in a large overall size that is inconvenient for transportation. Furthermore, the base is directly fixed to the ground with fasteners such as screws, leading to poor stability and reliability. Utility Model Content

[0003] The main purpose of this utility model is to propose a support base for installing towers and wind turbine generator sets, aiming to solve the technical problems of poor stability and reliability of current bases.

[0004] To achieve the above objectives, this utility model proposes a support base for installing a tower, the support base comprising:

[0005] A base, wherein the base has an installation space with an opening at the top;

[0006] A support column, the bottom end of which extends into the installation space from the opening; a limiting channel is formed inside the support column for the tower to extend into; multiple limiting grooves are spaced apart along the circumferential direction on the outer periphery of the bottom of the tower; the inner wall of the limiting channel is provided with a limiting protrusion extending vertically; the number of the limiting protrusions is the same as the number of the limiting grooves and they are set one-to-one; each of the limiting protrusions can be inserted and engaged with the corresponding limiting groove.

[0007] The support assembly includes multiple support rods, which are evenly spaced along the circumference of the support column. One end of each support rod is detachably connected to the base, and the other end of each support rod is detachably connected to the tower.

[0008] In one embodiment, the support column includes a connecting section and a support section, the support section being connected to the top of the connecting section, the connecting section extending into the installation space, the support section protruding outside the installation space, and the limiting channel being formed within the support section.

[0009] In one embodiment, a connecting ring is also provided on the outer periphery of the tower, and the first connecting ring is connected to the top of the support section, and one end of each support rod is detachably connected to the outer periphery of the connecting ring.

[0010] In one embodiment, the connecting ring is integrally formed with the tower, and a sealing ring is also provided between the connecting ring and the top of the support section.

[0011] In one embodiment, the outer diameter of the support section gradually increases from top to bottom.

[0012] In one embodiment, the top of the inner wall of the installation space is recessed outward to form an installation groove, and the top outer periphery of the connecting segment protrudes outward to form an installation step. At least a portion of the installation step can extend into the installation groove, and the bottom of the installation step is supported by the bottom wall of the installation groove.

[0013] In one embodiment, a plurality of limiting blocks are arranged at intervals along the circumference of the mounting groove, and the mounting step is provided with limiting holes. The number of limiting holes is the same as the number of limiting blocks and they are arranged in a one-to-one correspondence. Each limiting block can extend into a limiting hole.

[0014] In one embodiment, the mounting step is mounted on the mounting groove by a plurality of connecting rods. The mounting step has a plurality of first connecting holes extending vertically. The number of the first connecting holes is the same as the number of the connecting rods, and each of the first connecting holes communicates with a limiting hole. The limiting block has a second connecting hole at the position corresponding to the connecting hole, and each of the connecting rods is connected to the corresponding first connecting hole and the second connecting hole.

[0015] In one embodiment, the support assembly further includes a plurality of stabilizing rods, the number of which is the same as the number of supporting rods and they are arranged in a one-to-one correspondence. The two ends of each stabilizing rod are respectively connected to the tower and the corresponding supporting rod.

[0016] This utility model also proposes a wind turbine generator set, which includes blades, a nacelle, a tower, and a support base for mounting the tower as described above. The blades are disposed on the nacelle, and the nacelle is disposed on the top of the tower.

[0017] This utility model discloses a support base for installing a tower. By setting an installation space with a top opening on the base, and having one end of the support column extend into the installation space, it can effectively ensure the structural stability between the support column and the base. In addition, a limiting channel is formed inside the support column, and a limiting protrusion is set in the limiting channel. The limiting groove on the outer periphery of the bottom of the tower cooperates with the limiting protrusion, which can effectively increase the connection stability between the tower and the support column. In severe weather conditions such as strong winds, the cooperation of the limiting groove and the limiting protrusion can effectively prevent the support column from swaying or rotating relative to the support column, further preventing the wind turbine blades from swaying or turning, ensuring stable operation and good reliability. Furthermore, the base, support column, and tower can be disassembled and transported separately, reducing transportation difficulty. During on-site installation, only the support columns need to be installed together, and then the support columns are connected to the base to quickly complete the installation process, making it easy to install. In addition, by setting a support assembly, which includes multiple support rods, the two ends of the support rods are connected to the base and the tower, further improving the stability of the tower.

[0031] This utility model proposes a support base 100 for a tower 200.

[0032] Please see Figures 1 to 5In one embodiment of this utility model, the support base 100 includes a base 1, a support column 2, and a support assembly 3; the base 1 has an installation space 11 with an opening at the top; one end of the support column 2 extends into the installation space 11 from the opening; a limiting channel 221 for the tower cylinder 200 to extend into is formed in the support column 2; multiple limiting grooves (not shown) are spaced apart along the circumferential direction on the bottom outer periphery of the tower cylinder 200; the inner wall of the limiting channel 221 is provided with a limiting protrusion 222 extending vertically; the number of limiting protrusions 222 is the same as the number of limiting grooves and they are arranged in a one-to-one correspondence; each limiting protrusion 222 can extend into a limiting groove; the support assembly 3 includes multiple support rods 31, which are evenly spaced along the circumferential direction of the support column 2; one end of each support rod 31 is connected to the base 1, and the other end of each support rod 31 is connected to the top of the tower cylinder 200.

[0033] The support base 100 of the tower 200 of this utility model, by providing an installation space 11 with a top opening on the base 1, and having one end of the support column 2 extend into the installation space 11, effectively ensures the structural stability between the support column 2 and the base 1. Furthermore, a limiting channel 221 is formed within the support column 2. By providing multiple limiting protrusions 222 within the limiting channel 221, and by having the limiting groove on the outer periphery of the bottom of the tower 200 correspond one-to-one with the limiting protrusions 222, the connection stability between the tower 200 and the support column 2 can be effectively increased. Moreover, in adverse weather conditions such as strong winds, the matching of the limiting groove and the limiting protrusions 222 ensures stability. The system effectively prevents the support column 2 from swaying or rotating relative to the support column 2, further preventing the wind turbine blades from swaying or turning, ensuring stable operation and good reliability. Furthermore, the base 1, support column 2, and tower 200 can be disassembled and transported separately, reducing transportation difficulty. During on-site installation, the support column 2 only needs to be installed with the support column 2 and then connected to the base 1 to quickly complete the installation process, making it easy to install. In addition, the support assembly 3, which includes multiple support rods 31, is provided. The two ends of the support rods 31 are connected to the base 1 and the tower 200, further improving the stability of the tower 200.

[0034] In one embodiment, the support column 2 includes a connecting section 21 and a support section 22. The support section 22 is connected to the top of the connecting section 21. The connecting section 21 extends into the installation space 11, while the support section 22 protrudes outside the installation space 11. A limiting channel 221 is formed within the support section 22. By placing the support section 22 at the top of the connecting section 21 and providing the limiting channel 221 within the support section 22, the bottom of the tower 200 can be accurately aligned with the limiting groove and the limiting protrusion 222 when inserted, thereby improving assembly accuracy. Simultaneously, extending the connecting end outside the installation space 11 helps maintain the stability of the entire support column 2.

[0035] In one embodiment, a connecting ring 201 is also provided on the outer periphery of the tower 200, and the first connecting ring 201 is detachably connected to the top of the support section 22. One end of each support rod 31 is detachably connected to the outer periphery of the connecting ring 201. By providing a connecting ring 201 on the outer periphery of the tower 200, and having multiple support rods 31 evenly distributed around the tower 200 and all connected to the connecting ring 201, a support structure similar to "umbrella ribs" is formed. This helps the tower 200 better resist wind loads from all directions. In strong wind environments, it can also effectively prevent the tower 200 from swaying or tilting, thereby improving the stability and reliability of the wind turbine generator operation.

[0036] In one embodiment, the connecting ring 201 and the tower 200 are integrally formed, and a sealing ring (not shown) is provided between the connecting ring 201 and the top of the support section 22. By integrally forming the connecting ring 201 with the tower, the structure has good strength and stability. Furthermore, the connecting ring 201 is supported on the top of the support section 22, further dispersing the gravitational load of the tower 200, improving stability and reliability. Moreover, by providing the sealing ring, rainwater and other substances can be prevented from entering the limiting channel 221, preventing water accumulation from corroding the tower 200 and the sleeve 2, thus extending the service life.

[0037] In one embodiment, a first hinge seat is provided on the base 1 corresponding to each of the support rods 31, and a second hinge seat is provided on the outer periphery of the connecting ring 201 corresponding to each of the support rods 31. The two ends of each support rod 31 are hinged to the first hinge seat and the second hinge seat, respectively. By providing the first hinge seat and the second hinge seat on the base 1 and the connecting ring 201, respectively, and connecting the connecting rod 212 to the corresponding first hinge seat and second hinge seat, installation is quick and convenient, and the structure is simple and stable.

[0038] Specifically, the connecting ring 201 can be connected to the outer periphery of the tower 200 by welding, or the connecting ring 201 can be installed on the tower 200 by fasteners such as bolts.

[0039] Furthermore, the connecting ring 201 is connected to the top of the support section 22 via a screw, which further improves the stability of the tower 200 relative to the support column 2.

[0040] In one embodiment, the outer diameter of the support section 22 gradually increases from top to bottom. The gradual increase in the outer diameter of the support section 22 from top to bottom forms a cone-shaped or trapezoidal structure, which helps to more effectively transfer and distribute the load on the tower 200 downward to the base 1. The gradual increase in the outer diameter from top to bottom can improve the bending resistance of the support section 22, thereby enhancing the stability of the tower 200.

[0041] In one embodiment, the top of the inner wall of the mounting space 11 is recessed outward to form a mounting groove 12, and the outer periphery of the top of the connecting section 21 protrudes outward to form a mounting step 211. At least a portion of the mounting step 211 can extend into the mounting groove 12, and the bottom of the mounting step 211 is supported on the bottom wall of the mounting groove 12. By forming a mounting groove 12 on the inner wall of the mounting space 11 and forming a mounting step 211 protruding from the outer periphery of the connecting section 21, the mounting step 211 can extend into and be supported on the mounting step 211, increasing the contact area between the support column 2 and the base 1, which is more conducive to load distribution and also improves the vertical installation accuracy of the support column 2.

[0042] In other embodiments, a sealing ring is provided between the mounting step 211 and the bottom wall of the mounting groove 12 to prevent rainwater and other substances from entering the mounting space 11.

[0043] In other embodiments, the outer periphery of the mounting step 211 protrudes outward to form a flange, which is supported on the base 1. By forming the flange, the gap between the mounting step 211 and the mounting groove 12 can be effectively covered. The flange can effectively prevent rainwater and other substances from entering the mounting space 11 from the gap, thereby avoiding water accumulation and corrosion of the base 1 and the support column 2.

[0044] In one embodiment, a plurality of limiting blocks 121 are arranged at intervals along the circumference of the mounting groove 12, and the mounting step 211 is provided with limiting holes 2111. The number of limiting holes 2111 and the number of limiting blocks 121 are the same and are arranged in a one-to-one correspondence. Each limiting block 121 can extend into a limiting hole 2111.

[0045] By setting multiple limiting blocks 121 in the mounting groove 12, and the limiting blocks 121 can be inserted into the limiting holes 2111, the circumferential rotational freedom of the support section 22 in the mounting space 11 can be effectively restricted, which can prevent operational instability or structural damage caused by the rotation or displacement of the tower 200.

[0046] In the actual installation process, the bottom of the support section 22 can be inserted into the installation space 11 to achieve preliminary positioning. Then, by rotating the support column 2, each limiting block 121 and each limiting hole 2111 are aligned one by one to complete the installation between the support column 2 and the base 1.

[0047] In one embodiment, the mounting step 211 is mounted on the mounting groove 12 by a plurality of connecting rods 212. The mounting step 211 has a plurality of first connecting holes extending vertically. The number of first connecting holes is the same as the number of connecting rods 212, and each first connecting hole communicates with a limiting hole 2111. The limiting block 121 has a second connecting hole at the position corresponding to the connecting hole, and each connecting rod 212 is connected to the corresponding first connecting hole and the second connecting hole.

[0048] Understandably, by engaging the connecting rod 212 with the first and second connecting holes, the mounting step 211 can be securely fixed in the mounting groove 12, ensuring that the support column 2 will not loosen or shift under wind load or other external forces.

[0049] It should be noted that the connecting rod 212 can be a screw rod in the prior art, and both the first connecting hole and the second connecting hole can be screw holes.

[0050] In one embodiment, the support assembly 3 further includes a plurality of stabilizing rods 32, the number of which is the same as that of the support rods 31 and they are arranged in a one-to-one correspondence. The two ends of each stabilizing rod 32 are respectively connected to the support column 2 and the corresponding support rod 31.

[0051] By setting a stabilizing bar 32, which connects the support column 2 and the support rod 31 to form a triangular force-bearing structure, the instability of the support rod 31 such as bending and swaying can be effectively prevented, thereby improving the spatial stiffness and deformation resistance of the entire support assembly 3 and making it more reliable.

[0052] This utility model also proposes a wind turbine generator set, which includes blades, a nacelle, a tower 200, and a support base 100 for the tower 200 as described above. The blades are mounted on the nacelle, and the nacelle is located on top of the tower 200. The specific structure of the support base 100 for the tower 200 is as described in the above embodiments. Since this wind turbine generator set adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0053] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
