Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a wind turbine tower. Background Art

[0002] At present, wind turbines are installed in areas with good vegetation in the south. Due to the decrease in temperature and high ambient humidity, the wind turbines not only suffer from serious blade icing, but also due to problems such as the main wind direction, a thick layer of ice adheres to the surface of the wind turbine tower. When the ambient temperature gradually rises, the ice on the surface of the tower begins to melt. When melting, the ice rushes downward along the tower wall, and the tower door and tower escalator are often damaged by the sliding ice. In order to ensure the safety of the unit, the tower door and escalator need to be repaired or replaced after winter every year, causing great economic losses. If protective measures are not taken in time, it may also cause secondary losses such as the theft of high-value devices such as electrical cables inside the unit.

[0003] A wind turbine anti-icing tower ladder with Chinese patent publication number CN219953562U protects the tower door and tower ladder from falling ice by setting an anti-icing structure, thereby preventing the tower door and tower ladder from being damaged or reducing the degree of damage. Since the tower anti-icing ladder and the anti-icing structure are not directly connected to the tower, damage to the tower caused by welding or damage to the tower welding position caused by falling ice is avoided, thereby ensuring the safety and stability of the tower.

[0004] The contents described in the above patent still have the following defects in actual use:

[0005] (1) In summer, the possibility of ice forming on the tower surface is very small. The ice-breaking spikes are basically different. However, the ice-breaking spikes are always exposed to the outside. After being eroded by the environment, their service life is greatly shortened, which in turn affects the ice-breaking effect. Frequent replacement of ice-breaking spikes will also increase maintenance costs.

[0006] (2) When the ice breaker is in use, the protective plate will rotate to one side of the support frame. However, there are often strong winds in winter, which may blow the protective plate and cause it to move, which may not only damage the motor but also cause damage to the protective plate. Utility Model Content

[0007] In order to overcome the above-mentioned defects of the prior art, the inventors have conducted in-depth research and completed the present utility model after paying a lot of creative work.

[0008] Specifically, the technical problem to be solved by the present invention is to provide a wind turbine tower to solve the current problem that the possibility of ice formation on the tower surface in summer is very small, and the ice-breaking spikes are basically different.

[0032] like Figure 1 and Figure 5As shown together, this embodiment provides a wind turbine tower, including a tower 1, a foundation pedestal 2 is provided at the bottom of the tower 1, a tower door 3 is provided on the outside of the tower 1, a ladder 4 is provided on one side of the tower door 3, an anti-icing assembly 5 is provided on the top of the ladder 4, and locking assemblies 6 are provided on both sides of the anti-icing assembly 5;

[0033] The anti-icing assembly 5 includes a V-shaped top plate 51, a plurality of ice-breaking spikes 52 are provided on the top of the V-shaped top plate 51, an L-shaped plate 512 is symmetrically provided on one side of the V-shaped top plate 51, a motor 53 is installed on one side of the L-shaped plate 512, the output end of the motor 53 is connected to the first rotating shaft 54, the first rotating shaft 54 ​​is rotatably connected to the V-shaped top plate 51, a first gear 55 is provided on the first rotating shaft 54, a vertical plate 56 is symmetrically provided on the top of the V-shaped top plate 51, a second rotating shaft 57 is provided on the vertical plate 56, and the vertical plate 56 is connected to the second rotating shaft 57. 7 is rotatably connected, a second gear 58 is provided at one end of the second rotating shaft 57, and the second gear 58 is correspondingly meshed with the first rotating shaft 54. A curved plate 59 is symmetrically provided on the outer side of the second rotating shaft 57, and a protective plate 510 is provided on the top of the curved plate 59. The protective plate 510 is driven to rotate by the motor 53. The protective plate 510 covers the ice-breaking spikes 52, preventing the ice-breaking spikes 52 from being exposed to the outside and being corroded by the environment when the ice-breaking spikes 52 are not working. This not only improves the service life of the ice-breaking spikes 52, but also does not affect the ice-breaking effect.

[0034] The V-shaped top plate 51 is in an inverted V shape, and there is a gap between the V-shaped top plate 51 and the tower 1. A support frame 513 is symmetrically provided at the bottom of the V-shaped top plate 51. The inverted V shape of the V-shaped top plate 51 is more conducive to the falling of crushed ice and reduces the load-bearing capacity of the V-shaped top plate 51.

[0035] A limiting plate 511 is provided on the top of the V-shaped top plate 51 away from the tower 1 . A plurality of supporting blocks 514 are provided on the top of the V-shaped top plate 51 . The supporting blocks 514 support the protective plate 510 .

[0036] like Figure 1 、 Figure 4 and Figure 5 As shown together, the locking assembly 6 includes a fixing plate 61, and the two fixing plates 61 are symmetrically arranged on one side of the support frame 513. A storage chamber 62 is provided on one side of one fixing plate 61, and an arc-shaped limit block 63 is provided inside the storage chamber 62. A slide rod 64 is provided on one side of the arc-shaped limit block 63, and a spring 65 is sleeved on the outer surface of the slide rod 64. The spring 65 is arranged between the storage chamber 62 and the arc-shaped limit block 63. A circular plate 66 is provided at one end of the slide rod 64, and a plug-in ear 67 is provided on the top of the protective plate 510. The plug-in ear 67 on the protective plate 510 is locked by the arc-shaped limit block 63, and then the protective plate 510 is limited, so that in windy weather, the protective plate 510 will not be blown, and the protective plate 510 will not move, thereby avoiding damage to the motor.

[0037] A sliding groove 68 is provided on the other side of the fixed plate 61, and the sliding groove 68 is slidably connected to a clamping plate 69. A spring 2 610 is provided between the clamping plate 69 and the support frame 513. The tension of the spring 2 610 pushes the clamping plate 69 to squeeze the plug-in ear 67 to prevent the protective plate 510 from shaking.

[0038] One side of the arc-shaped limit block 63 is an arc-shaped surface, the arc-shaped limit block 63 is slidably connected to the storage chamber 62, and the slide rod 64 is slidably connected to the storage chamber 62. The arc-shaped limit block 63 is guided by the storage chamber 62, and the slide rod 64 is guided by the storage chamber 62.

[0039] When the ice breaker 52 is in operation, the staff starts the motor 53, and the motor 53 drives the first gear 55 to rotate through the first shaft 54, and the first gear 55 drives the second shaft 57 to rotate through the second gear 58, and the second shaft 57 drives the protective plate 510 to rotate through the arc plate 59 until the protective plate 510 hits the support block 514, and then stops the motor 53. The ice breaker 52 is covered by the two protective plates 510, which prevents the ice breaker 52 from being exposed to the outside when it is not working and being eroded by the environment. This not only improves the service life of the ice breaker 52, but also does not affect the ice-breaking effect, and does not need to be replaced frequently, reducing maintenance costs. In winter, when the ice breaker 52 is working, the motor 53 is started, and the motor 53 drives the protective plate 510 to rotate, and the two protective plates 510 rotate in the direction away from the ice breaker 52 until the plug-in ear 67 hits the plug-in ear 67. The tension of the spring 610 pushes the clamping plate 69 to squeeze the plug-in lug 67, preventing the protective plate 510 from shaking. The protective plate 510 is limited by the arc limit block 63 and the clamping plate 69, so that in strong winds, the protective plate will not be blown and will not move, which not only avoids damage to the motor but also does not cause damage to the protective plate.
