Large stator segment arc downward support base

Abstract

This utility model discloses a support base for a large stator lobe with its arc surface facing downwards, relating to the field of support technology for large stator lobe arc surfaces facing downwards. It includes a support base plate, with limiting support blocks installed on both sides of the top of the support base plate. The top of each limiting support block has a first arc surface area, and a first pre-drilled hole is provided at the top of the limiting support block. The limiting support block is connected to the support base plate by hexagonal bolts. In this utility model, the setting of the limiting support blocks, support base plate, and arc surface area allows for the placement of a large stator lobe arc surface downwards on the assembly formed by the support base plate and the limiting support blocks. The support surface of the device is an arc surface with the same radius as the large stator lobe arc surface. During support, the large stator lobe arc surface contacts the arc surface of the support base. The large contact area results in a smaller force, and the arc surface itself has a limiting function. Therefore, this support base combines support and fixation functions, meeting various support conditions.

Description

Technical Field

[0001] This utility model relates to the field of large stator lobe arc-shaped downward support technology, and in particular to a large stator lobe arc-shaped downward support base. Background Technology

[0002] Compared with traditional stators, segmented stators for wind turbines have advantages such as small size, easy maintenance, and convenient transportation and installation. They are currently widely used in offshore wind turbines. With the segmented stator structure, a stator is divided into multiple stator segments, which means that each stator segment requires a separate fixed support.

[0003] Currently, the most common support method is the upward-curved support of the stator segments. In this method, the stator support is in direct contact with the support base, and the entire weight of the stator core rests on the support. Over time, this will inevitably lead to deformation of the support. Furthermore, the upward-curved support method generally only provides support and does not provide fixation. If it is to be used in transportation applications, welding or the addition of stop structures is often required, which is costly and relatively complex. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing stator support methods that use an upward-facing stator lobe arc surface. In this method, the stator support is in direct contact with the support base, and the entire weight of the stator core rests on the support, inevitably leading to deformation over time. Furthermore, upward-facing arc surface support generally only provides support without fixing, and for use in transportation applications, welding or adding stop structures is often required, resulting in higher costs and greater complexity. Therefore, this invention proposes a large stator lobe arc surface downward-facing support base.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A large stator lobe arc-shaped downward support base includes:

[0007] A supporting base plate is provided, with limiting support blocks installed on both sides of the top of the supporting base plate. The top of the limiting support block is provided with a first arc surface area. The top of the limiting support block is provided with a first reserved hole. The limiting support block is connected to the supporting base plate by a hexagonal bolt. The top center of the supporting base plate is provided with a second arc surface area. The top sides of the supporting base plate are provided with second reserved holes. Nuts are installed inside the second reserved holes. The inner side of the nuts is threadedly connected to the hexagonal bolts.

[0008] Preferably, the supporting base plate and the limiting support block are both made of wood.

[0009] Preferably, the side of the limiting support block has a triangular curved surface structure.

[0010] Preferably, the radius of the circle containing the first arc surface area is equal to the radius of the circle containing the second arc surface area.

[0011] Preferably, the center line of the first reserved hole coincides with the center line of the second reserved hole.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] 1. In this utility model, by setting up limiting support blocks, supporting base plates, and arc-shaped areas, people can place the large stator lobe arc-shaped surface downwards on the combination of the supporting base plate and the limiting support blocks. The supporting surface of the device is an arc surface with the same radius as the arc surface of the large stator lobe. During support, the arc surface of the large stator lobe contacts the arc surface of the support base. The contact area is large, so the force is small. The arc surface itself has a limiting function. Therefore, the support base has both supporting and fixing functions, which can meet various support conditions. In addition, the device adopts a modular design, which can achieve universal support. First, it can save materials. According to different models and radii of stator lobes, the limiting support blocks with the appropriate applicable radius can be replaced. Second, it is convenient to support. Two or more support bases can be combined to achieve the purpose of supporting the stator lobe according to different working conditions. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1-3A large stator lobe arc-shaped support base includes a support base plate 1. Limiting support blocks 2 are installed on both sides of the top of the support base plate 1, and the top of the limiting support blocks 2 is provided with a first arc surface area 3. The support base plate 1 and the limiting support blocks 2 are both made of wood, which saves material costs. The top of the limiting support blocks 2 is provided with a first reserved hole 4, and the limiting support blocks 2 are connected to the support base plate 1 by hexagonal bolts 6. The top center of the support base plate 1 is provided with a second arc surface area 5, and the top sides of the support base plate 1 are provided with second reserved holes 7. The center line of the first reserved hole 4 coincides with the center line of the second reserved hole 7. Through their distribution, the hexagonal bolts 6 are passed through the first reserved hole 4 and then threadedly connected to the nuts 8, thereby completing the connection between the support base plate 1 and the limiting support blocks 2. Nuts 8 are installed on the inner side of the second reserved hole 7, and the inner side of the nuts 8 is threadedly connected to the hexagonal bolts 6.

[0021] The side of the limiting support block 2 has a triangular curved surface structure. The symmetrically distributed limiting support blocks 2 can provide auxiliary support on both sides of the large stator lobe arc surface. The second arc surface area 5 at the support base plate 1 serves as the main support area. The radius of the circle containing the first arc surface area 3 is equal to the radius of the circle containing the second arc surface area 5. By setting the first arc surface area 3 at the top of the limiting support block 2, it can be smoothly connected with the second arc surface area 5, which facilitates better support for the downwardly placed large stator lobe arc surface.

[0022] Working principle: In use, the operator first connects the limiting support block 2 to the supporting base plate 1 by passing the hexagonal bolt 6 through the first reserved hole 4 and then threading it with the nut 8 embedded in the second reserved hole 7. This completes the connection between the supporting base plate 1 and the limiting support block 2. Then, the large stator lobe is placed with its arc surface facing down on the assembly formed by the supporting base plate 1 and the limiting support block 2, so that the supporting surface of the device is an arc surface with the same radius as the arc surface of the large stator lobe. During support, the arc surface of the large stator lobe contacts the arc surface of the support base. The contact area is large, so the force is small. The arc surface itself has a limiting function. Therefore, the support base has both support and fixing functions, which can meet various support conditions. Two or more support bases can be combined to achieve the purpose of supporting the stator lobe according to different working conditions. (It should be noted that the specific model and specifications of the electrical parts involved in this solution need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.)

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
