Description

Technical Field

[0001] This utility model belongs to the field of generator towers, and specifically relates to a wind turbine tower with a reinforced structure. Background Technology

[0002] As a traditional form of tall structure, cable-stayed towers can effectively solve the drawbacks caused by the limitation of the bottom diameter of traditional steel towers due to transportation conditions by distributing only part of the external load to the main body of the steel cylinder through a reasonable force transmission path, while the other part is transmitted through cables. Furthermore, by cooperating with the relatively mature steel tower and flange industry chain, the overall cost of the tower can be reduced.

[0003] A search revealed that Chinese Patent CN212535934U discloses a cable-stayed steel cylinder tower for a wind turbine generator set, comprising a tower section, characterized in that it further comprises: a tower transition section, a cable flange, and a cable; the tower transition section has tower transition section flanges at both ends, and the tower transition section flanges are provided with flange bolt holes; the cable flange is provided with cable flange bolt holes, and cable flange ear plates are provided on its outer wall; the cable flange is located between two tower transition sections, and flange connecting bolts pass through the flange bolt holes and the cable flange bolt holes to connect the two tower transition sections and the cable flange together; the tower section is connected to the outer ends of the two tower transition sections, and one end of the cable is connected to the cable flange ear plate, and the other end is connected to a ground anchor point.

[0004] The generator tower structure in the above-mentioned prior art strengthens and reinforces the tower as a whole by adding cable flanges and anchor points. However, there are still some shortcomings in practical applications. For example, the anchor cones of the anchor points are generally driven directly into the ground. This works well for some geological areas with high strength, but the effect is not ideal for some geological areas with weak strength. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a wind turbine tower with a reinforced structure to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A wind turbine tower with a reinforced structure includes a tower body and a reinforced anchor. The outer side of the tower body is provided with a cable flange, and the outer side of the cable flange is provided with a steel cable. The reinforced anchor is movably installed through a connecting mechanism and the end of the steel cable away from the cable flange. A reinforced cone is fixedly installed at the lower end of the reinforced anchor. A reinforcing mechanism is provided on the inner side of the reinforced anchor.

[0008] The reinforcing mechanism includes an installation cavity located inside the reinforcing cone. A rotating rod is rotatably connected to the inner side of the installation cavity. A circular groove is provided at the upper end of the reinforcing anchor. A second hexagonal block is fixedly installed at the upper end of the rotating rod extending into the circular groove. A second bevel gear is fixedly installed on the outer side of the rotating rod. A receiving groove is provided on the outer side of the reinforcing cone. A second screw is rotatably connected to the inner side of the receiving groove. A first bevel gear is fixedly installed at one end of the second screw extending into the inner side of the installation cavity. The first bevel gear and the second bevel gear are meshed. A reinforcing cone is slidably connected to the inner side of the receiving groove. One end of the reinforcing cone is threadedly connected to the second screw.

[0009] The connecting mechanism includes an assembly base, which is rotatably connected to the upper end of the reinforcing anchor. A connecting block is rotatably connected to the inner side of the upper end of the assembly base. A connecting rod is welded to the upper end of the connecting block. A connecting seat is welded to the upper end of the connecting rod. A first hexagonal block is rotatably connected to the end of the steel cable away from the cable flange. A first screw is fixedly installed at the end of the first hexagonal block away from the steel cable. The end of the first screw away from the first hexagonal block is threaded to the inner side of the upper end of the connecting seat.

[0010] As a preferred technical solution, an inner threaded sleeve is fixedly installed on the inner side of the upper end of the connecting seat, and one end of the first screw is threadedly connected to the inner side of the inner threaded sleeve.

[0011] As a preferred technical solution, the lower end of the mounting base is rotatably connected to a positioning plate, and the upper end of the reinforcing anchor is provided with a positioning groove. The positioning plate is fixedly installed inside the positioning groove by screws.

[0012] As a preferred technical solution, the inner side of the storage groove is symmetrically provided with limiting grooves, and one end of the reinforcing cone and the limiting groove are slidably connected.

[0013] As a preferred technical solution, the outer side of the reinforcing cone is provided with eight storage slots at equal angles, and the number of reinforcing cones corresponds to the number of storage slots.

[0014] As a preferred technical solution, the lower end of the tower body is provided with a mounting base, and the mounting base is in the shape of a disc.

[0015] In summary, the present invention has the following main advantages:

[0016] First, by using a wrench or an operating turntable adapted to the second hexagonal block, after inserting it into the second hexagonal block, the second hexagonal block drives the rotating rod to rotate in the mounting cavity. The rotation of the rotating rod causes the outer second bevel gear to mesh with the first bevel gear. At the same time, the second screw connected to the first bevel gear can rotate in the receiving groove. The rotation of the second screw causes the reinforcing cone connected to the outer thread to slide out from the receiving groove. When the reinforcing cone penetrates into the geology, it can greatly enhance the strength and stability of the reinforced anchor.

[0017] Secondly, by installing the mounting base on the reinforced anchor, since the rotating connecting block on the mounting base is connected to the connecting base through the connecting rod, one end of the steel cable at the cable flange of the tower body can be connected to the connecting base through the first screw, thus making it easy to adjust the steel cable to a taut state and enhance its fault tolerance.

[0023] refer to Figures 1 to 4The wind turbine tower with a reinforced structure described in this embodiment includes a tower body 1 and a reinforced anchor 5. A cable flange 3 is provided on the outer side of the tower body 1, and a steel cable 4 is provided on the outer side of the cable flange 3. The reinforced anchor 5 is movably installed at the end of the steel cable 4 away from the cable flange 3 through a connecting mechanism 7. A reinforced cone 6 is fixedly installed at the lower end of the reinforced anchor 5, and a reinforcing mechanism 8 is provided on the inner side of the reinforced anchor 5. The cable flange 3 is located at the tower transition section of the tower body 1, which is a known prior art structure, so it will not be described in detail here.

[0024] The reinforcing mechanism 8 includes a mounting cavity 806, which is located inside the reinforcing cone 6. A rotating rod 807 is rotatably connected to the inner side of the mounting cavity 806. A circular groove 801 is provided at the upper end of the reinforcing anchor 5. A second hexagonal block 802 is fixedly installed in the circular groove 801 at the upper end of the rotating rod 807. A second bevel gear 809 is fixedly installed on the outer side of the rotating rod 807. A receiving groove 803 is provided on the outer side of the reinforcing cone 6. A second screw 804 is rotatably connected to the inner side of the receiving groove 803. One end of the second screw 804 extends into the inner side of the mounting cavity 806 and a first bevel gear 808 is fixedly installed thereon. The first bevel gear 808 and the second bevel gear 809 are meshed. A reinforcing cone 805 is slidably connected to the inner side of the receiving groove 803. One end of the reinforcing cone 805 and... The second screw 804 is threaded. On the ground-mounted foundation of the reinforced anchor 5 with the reinforcing cone 6, a wrench or an operating turntable adapted to the second hexagonal block 802 is inserted into the second hexagonal block 802. After rotation, the second hexagonal block 802 drives the rotating rod 807 to rotate in the mounting cavity 806. The rotation of the rotating rod 807 causes the outer second bevel gear 809 to mesh with the first bevel gear 808. At the same time, the second screw 804 connected to the first bevel gear 808 can rotate in the receiving groove 803. The rotation of the second screw 804 causes the outer threaded reinforcing cone 805 to slide out from the receiving groove 803. When the reinforcing cone 805 penetrates into the geology, it can greatly enhance the strength and stability of the reinforced anchor 5.

[0025] The connecting mechanism 7 includes an assembly base 701, which is rotatably connected to the upper end of the reinforcing anchor 5. A connecting block 702 is rotatably connected to the inner side of the upper end of the assembly base 701. A connecting rod 703 is welded to the upper end of the connecting block 702, and a connecting seat 704 is welded to the upper end of the connecting rod 703. A first hexagonal block 706 is rotatably connected to the end of the steel cable 4 away from the cable flange 3. A first screw 705 is fixedly installed at the end of the first hexagonal block 706 away from the steel cable 4, and a threaded connection is made to the end of the first screw 705 away from the first hexagonal block 706. On the upper inner side of the connecting seat 704, on the basis of the reinforced anchor seat 5, the assembly seat 701 is installed on the reinforced anchor seat 5. Since the rotating connecting block 702 on the assembly seat 701 is connected to the connecting seat 704 through the connecting rod 703, one end of the steel cable 4 at the cable flange 3 of the tower body 1 can be connected to the connecting seat 704 through the first screw 705, so that the steel cable 4 can be easily adjusted to a taut state, enhancing its fault tolerance effect; one end of the steel cable 4 is rotatably connected to the first hexagonal block 706, and the two cannot be separated.

[0026] refer to Figure 2 An inner threaded sleeve 9 is fixedly installed on the inner side of the upper end of the connecting seat 704. One end of the first screw 705 is threadedly connected to the inner side of the inner threaded sleeve 9. The first screw 705 and the connecting seat 704 can be threadedly connected through the inner threaded sleeve 9 on the connecting seat 704.

[0027] refer to Figure 2 The lower end of the mounting base 701 is rotatably connected to a positioning plate 11, and the upper end of the reinforcing anchor 5 is provided with a positioning groove 10. The positioning plate 11 is fixedly installed inside the positioning groove 10 by screws. The positioning plate 11 on the mounting base 701 can be conveniently positioned and installed with the reinforcing anchor 5. The mounting base 701 and the positioning plate 11 are rotatably connected and cannot be separated.

[0028] refer to Figure 3 A limiting groove 12 is symmetrically provided on the inner side of the storage groove 803. One end of the reinforcing cone 805 and the limiting groove 12 are slidably connected. Through the limiting groove 12 at the storage groove 803, the reinforcing cone 805 can be easily limited and slid, preventing it from coming out of the storage groove 803.

[0029] refer to Figure 2 The outer side of the reinforcing cone 6 is provided with eight storage slots 803 at equal angles. The number of reinforcing cones 805 corresponds to the number of storage slots 803. By connecting the multiple storage slots 803 at equal angles on the outer side of the reinforcing cone 6 with the corresponding reinforcing cones 805 in the storage slots 803, the strength and stability of the reinforcing cones 805 can be ensured after adjustment.

[0030] refer to Figure 1The lower end of the tower body 1 is provided with a mounting base 2, which is disc-shaped. The tower body 1 can be easily installed and used through the mounting base 2 on the tower.

[0031] Operating principle and advantages: During use, the tower body 1 is first installed using the mounting base 2. Then, the reinforcing anchor 5 with the reinforcing cone 6 is fixed to the surrounding ground by measurement. Using a wrench or an operating turntable adapted to the second hexagonal block 802, after being inserted into the second hexagonal block 802, the second hexagonal block 802 drives the rotating rod 807 to rotate in the mounting cavity 806. The rotation of the rotating rod 807 causes the outer second bevel gear 809 to mesh with the first bevel gear 808. At the same time, the second screw 804 connected to the first bevel gear 808 can rotate in the receiving groove 803. The rotation of the second screw 804 causes the reinforcing cone 805 connected to the outer thread to slide out from the receiving groove 803. When the reinforcing cone 805 penetrates into the soil, the anchor 5 is reinforced.

[0032] Then, based on the installation of the reinforced anchor 5, the assembly seat 701 is partially installed on the reinforced anchor 5 through the positioning plate 11. Since the rotating connecting block 702 on the assembly seat 701 is connected to the connecting seat 704 through the connecting rod 703, one end of the steel cable 4 at the cable flange 3 of the tower body 1 is connected to the connecting seat 704 through the first screw 705 and adjusted to a taut state.
