Description

Technical Field

[0001] The invention relates to the technical field of generator towers, and in particular to a generator tower for a high-turbulence mountain wind farm. Background Art

[0002] The tower of a wind turbine generator set can support the generator set and absorb the vibration generated by the generator set, playing an important role in the entire wind turbine generator set. After searching, the prior art (publication number: CN219795453U) records "a wind turbine tower segment, tower and wind turbine. The tower segment includes a plurality of tower segments and connectors. The plurality of tower segments are spliced ​​along the circumferential direction to form an annular tower segment. The two opposite splicing sides of each tower segment are respectively provided with protrusions and grooves arranged along the length direction thereof. The protrusions and grooves of each tower segment correspond to the grooves and protrusions of the adjacent tower segments one by one and are arranged in a matching manner. The connector is arranged through the protrusions and grooves after each adjacent two tower segments are spliced ​​along the length direction of the tower segment, and is suitable for connecting each adjacent two tower segments. The protrusions and grooves of the tower of the wind turbine of the present invention can reduce the force on the connector, avoid deformation and failure of the connector under the action of a large force, and prevent the tower segments from breaking free at the splicing point." Although the wind turbine tower segments in the prior art have achieved connection stability, there are still some shortcomings: when the existing wind turbine tower is installed and used in high-turbulence mountainous areas, due to the variability of wind force and wind direction in high-turbulence wind groups, more non-directional thrust and excitation are caused to the tower, which in turn leads to tower instability. Secondly, the existing tower bottom is relatively simple to fix and is also not suitable for use in high-turbulence mountain wind farms. Summary of the invention

[0003] In order to overcome the defects of the prior art, a high-turbulence mountain wind farm generator tower and an anti-turbulence method are provided to solve the problems of installation and fixation stability deviation and anti-turbulence wind effect deviation of the existing wind turbine generator tower when used in high-turbulence mountain wind farms.

[0004] To achieve the above-mentioned purpose, a high-turbulence mountain wind farm generator tower is provided, comprising: a tower body, the tower body comprising a plurality of connected cylinder sections, and the cylinder sections are connected by connecting assemblies, and a force unloading assembly is rotatably connected to the outer side of the cylinder section, and a fixing assembly is connected to the bottom of the tower body, the force unloading assembly comprises a bearing fixed to the outer wall of the cylinder section, and a shaft sleeve is fixed to the outer side of the bearing, and a fan blade is connected to the outer wall of the shaft sleeve, the fixing assembly comprises a base plate connected to the outer wall of the tower body, and a conical pile is connected to the middle of the lower end of the base plate, and a reinforcing rod is connected to the outer wall of the conical pile.

[0005] Furthermore, the outer edges of the upper and lower ports of the barrel section are respectively connected to the first threaded barrel and the second threaded barrel, and a groove is provided at one end of the barrel section, and a protrusion is provided at the other end, and the protrusion is matched and plugged into the groove.

[0006] Furthermore, the first threaded barrel and the second threaded barrel correspond to each other in upper and lower positions, and the first threaded barrel and the second threaded barrel are provided with the same threads inside, and the first threaded barrel and the second threaded barrel are connected by a locking bolt.

[0007] Furthermore, the force unloading components are provided in multiple groups in the vertical direction of the tower body, and spacing is provided between the multiple groups of force unloading components, and the installation position of the force unloading components is avoided from the position of the connection components.

[0008] Furthermore, the blades are arranged at equal intervals along the outer wall of the sleeve, and the outer edges of the blades are kept parallel to the tower body in the vertical direction.

[0009] Furthermore, a driving bolt is threadedly connected to the interior of the base plate, and the driving bolt is located on the upper side of the reinforcing rod, and an insert is connected to the lower side of the reinforcing rod.

[0010] Furthermore, the two ends of the base plate are hinged with a flip plate, and the two ends of the flip plate are respectively connected to a first connecting plate and a second connecting plate, and the adjacent first connecting plates and the second connecting plates are connected by positioning bolts.

[0011] When used in a high-turbulence mountain wind farm, the conical piles at the bottom of the tower are first buried in a preset slot in the ground, and then backfilled. At this time, the reinforcing rod is in an inclined state in the preset slot, and then the driving bolt is turned to move it downward until the reinforcing rod is squeezed, so that the reinforcing rod is bent and deformed downward until the insert is vertically inserted into the ground. At this time, the reinforcing rod remains in a horizontal state, and then the base plates at the lower ends of adjacent towers are connected by positioning bolts through the flip plate and the connecting plate, so that the bottom of the tower installed in the high-turbulence wind farm has a mutually linked structure, thereby achieving stability in installation and fixation; when a turbulent wind group acts on the tower body, the force unloading assembly on the outside of the tower body, and the fan blades, shaft sleeves and bearings included in the force unloading assembly, are blown to rotate by the fan blades. When turbulent wind groups of different wind directions act on the fan blades at different positions, different reverse force unloading effects are exerted on the tower body, and the rotating fan blades form wind circles around them, which have a post-impact dispersion effect on each high-turbulence wind group.

[0012] The beneficial effects of the present invention are: 1. When used in a high-turbulence mountain wind farm, first bury the conical piles at the bottom of the tower in the preset slots underground, and then backfill. At this time, the reinforcement rod is tilted and located in the preset slots. Then turn the drive bolts to move it downward until it squeezes the reinforcement rods, causing them to bend and deform downward until the inserts are vertically inserted into the ground. At this time, the reinforcement rods remain horizontal. Then, through the flip plate and the connecting plate, the base plates at the lower ends of the adjacent towers are connected by positioning bolts, so that the bottom of the tower installed in the high-turbulence wind farm has a mutually linked structure, thereby achieving stability in installation and fixation. 2. During use, when turbulent wind groups appear and act on the tower body, the force unloading assembly on the outside of the tower body, as well as the fan blades, shaft sleeves and bearings included in the force unloading assembly, are blown by the fan blades to achieve rotation. When turbulent wind groups of different wind directions act on the fan blades at different positions, different reverse force unloading effects are exerted on the tower body. The rotating fan blades form wind circles around them, which have a dispersing effect on each high-turbulence wind group after impact, thereby reducing the direct thrust of the high-turbulence wind group on the tower, thereby reducing the excitation to the tower and enhancing the tower's resistance to high-turbulence wind.

[0019] In this embodiment, the cylinder segment 11, the connecting assembly 2, the unloading assembly 3 and the fixing assembly 4 constitute the overall tower structure of the generator set in the high turbulence mountain wind farm involved in this application, which is used for the tower structure of the generator set installed in the high turbulence mountain wind farm.

[0020] Specifically, the connecting plates at both ends of the same base plate 41 have a height difference, and remain flush with the upper and lower end surfaces of the flip plate 43 after being pressed together.

[0021] As a preferred embodiment, the base plates 41 at the lower ends of adjacent tower bodies 1 are connected by means of the flip plate 43 and the connecting plate, thereby strengthening the tightness of the connection between the multiple towers and the firmness of the bottom interconnection.

[0022] Specifically, the driving bolt 42 corresponds to the lower reinforcing rod 45 in vertical position, and the reinforcing rod 45 is configured as a sheet metal structure.

[0023] As a preferred embodiment, the driving bolt 42 is provided to facilitate pressing the reinforcing rod 45 downward to bend it, so that the inserting strip 46 is inserted downward, thereby increasing the overall pullout resistance of the tapered pile 44 .

[0024] like Figure 2 As shown, the outer edges of the upper and lower ports of the barrel section 11 are respectively connected to the first threaded barrel 21 and the second threaded barrel 22, and a groove is provided at one end of the barrel section 11, and a protrusion 23 is provided at the other end, and the protrusion 23 is matched and plugged into the groove, the first threaded barrel 21 and the second threaded barrel 22 correspond in upper and lower positions, and the first threaded barrel 21 and the second threaded barrel 22 are provided with the same threads inside, and the first threaded barrel 21 and the second threaded barrel 22 are connected by locking bolts.
