A multi-functional rear base structure for wind turbine generator sets

Abstract

This utility model discloses a multifunctional rear base structure for a wind turbine generator set, including a rear base, a mounting bracket, and reinforcing ribs. The rear base includes a main plate and a web plate. The main plate is connected to both sides of the web plate and is vertically positioned in the middle of the main plate. The mounting bracket is installed above the main plate and aligned with the web plate in a straight line. Reinforcing ribs are provided on both sides of the mounting bracket. The mounting bracket can form a detachable connection with the turning gear of the wind turbine generator set. Compared with the prior art, this utility model can integrate a mounting bracket that bears the weight of the main unit and can also bear the reaction force weight of the turning gear. Because the strength of the rear base and the mounting bracket is much stronger than the reaction force of the turning gear, the turning gear can be installed through the mounting bracket without the need for bolts to be tightened to torque, making installation more convenient and safer.

Description

Technical Field

[0001] This utility model relates to the technical field of wind turbine generator set bases, and in particular to a multi-functional rear base structure for wind turbine generator sets. Background Technology

[0002] Currently, the main purpose of the wind turbine's mounting base is to support the lifting of the main unit and transport it to the top of the tower, and it can bear the weight of the main unit. The turning gear on the wind turbine is generally installed on the flat steel plate of the rear base, and the turning gear is tightened by applying torque with bolts. Then, the reaction force of the turning gear rotates the wind turbine's rotor to a certain position and locks it. However, when tightening the turning gear with bolts, if the bolt torque value does not reach the required standard value, or if the bolt strength value and length do not meet the standard values, the bolt is prone to breakage, which may lead to dangerous incidents of injury caused by the reaction force of the turning gear. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing a multi-functional rear base structure for wind turbine generator sets. This structure integrates a support bracket to bear the weight of the main unit and the reaction force of the turning gear. Since the strength of the rear base and the support bracket is much greater than the reaction force of the turning gear, the turning gear can be installed through the support bracket without the need for bolts to be tightened to torque, making installation more convenient and safer.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows: a multi-functional rear base structure for a wind turbine generator set, comprising a rear base, a mounting bracket, and reinforcing ribs; the rear base includes a main plate and a web plate, the main plate is connected to both sides of the web plate and is vertically arranged in the middle of the main plate, the mounting bracket is installed above the main plate and aligned with the web plate on the same straight line, and reinforcing ribs are provided on both sides and below the mounting bracket, and the mounting bracket can form a detachable connection with the turning gear of the wind turbine generator set.

[0005] Furthermore, the lifting bracket is provided with lifting holes for connecting to the turning gear, main unit lifting straps and shackles of the wind turbine generator set.

[0006] Furthermore, the mounting bracket can be detachably connected to the main lifting device of the wind turbine generator set via the main lifting strap and shackle.

[0007] Furthermore, two reinforcing ribs are provided on each side of the hanging base.

[0008] Compared with the prior art, this utility model has the following advantages and beneficial effects: This utility model has a simple and stable structure, and is equipped with a lifting and bearing function. It can directly lift the main body through slings and shackles, and can also directly bear the reaction force of the lever arm generated by the turning device during operation. It will not cause the turning device to lose control. The bearing capacity of the lifting base is much stronger than the reaction force of the turning device. The turning device is installed on the main body lifting base for turning, which changes the previous method of using bolts to tighten the torque. It will not cause bolts to loosen or break, or the turning device to lose control, thus ensuring safety. Attached Figure Description

[0013] The present invention will be further described below with reference to specific embodiments.

[0014] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0015] See Figures 1 to 4 As shown, the multi-functional rear base structure of the wind turbine generator set provided in this embodiment includes a rear base, a mounting bracket 3, and a reinforcing rib plate 4.

[0016] The rear base includes a main plate 1 and a web plate 2. The main plate 1 is connected to both sides of the web plate 2 and is vertically set in the middle of the main plate 1. The lifting seat 3 is welded above the main plate 1 and aligned with the web plate 2 in a straight line. Two first reinforcing ribs 4-1 are welded to both sides of the lifting seat 3. A second reinforcing rib 4-2 is provided below the lifting seat 3. The two ends of the second reinforcing rib 4-2 are connected to the main plate 1. The lifting seat 3 can form a detachable connection with the turning gear 5 of the wind turbine generator set, realizing the function of supporting and installing the turning gear 5. In addition, the lifting seat 3 is provided with lifting holes for connecting with the turning gear 5, the main lifting strap 6 and the shackle 8 of the wind turbine generator set. The lifting seat 3 can be detachably connected to the main lifting tool 7 of the wind turbine generator set through the main lifting strap 6 and the shackle 8, realizing the basic main lifting function.

[0017] The lifting base 3 is detachably equipped with a turning device 5. The turning device 5 does not require bolts for torque tightening, making balance adjustment more convenient. It can directly bear the reaction force of the lever arm 'a' generated by the turning device 5 during operation, preventing the turning device 5 from going out of control, thus making it more convenient and safer. At the same time, the lifting base 3 is welded to the rear base main plate 1 and is aligned with the web plate 2. This setting optimizes the mechanical force transmission and stress distribution of the overall structure, and it is firmly fixed into a whole through fusion welding. The lifting base 3 has four first reinforcing rib plates 4-1 and second reinforcing rib plates 4-2 to assist welding and achieve reinforcement.

[0018] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all changes made in accordance with the shape and principle of this utility model should be covered within the protection scope of this utility model.
