Description

Technical Field

[0001] The utility model relates to the technical field of wind power transmission and distribution, and more specifically, to a stator mounting bracket assembly. Background Art

[0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. During the process of wind power generation, components for power transmission and distribution are required, such as mounting brackets for fixing cables in towers. Among them, in order to resist strong winds and earthquakes, in some areas, the connection method of replacing rectangular busbars with aluminum alloy tubular cross-section conductors and flexible connection parts for cables is selected to enhance the connection stability. When the flexible connection method is affected by strong winds or earthquakes, the flexible connection part will have slight fluctuations to achieve force relief, while the existing brackets for mounting stators generally fix the position when installing cables, resulting in poor compatibility. In view of this, we propose a stator mounting bracket assembly. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a stator mounting bracket assembly to solve the technical problem of poor compatibility between the current mounting bracket and the flexible connection.

[0004] To solve the above technical problems, the utility model provides the following technical solutions: A stator mounting bracket assembly includes a first stator end plate, a connecting channel steel, and a second stator end plate. The first stator end plate and the second stator end plate are respectively fixed to both ends of the connecting channel steel. A stator adjusting support plate is arranged on one side of the second stator end plate. Brackets are connected to one side of both the stator adjusting support plate and the first stator end plate. Two flexible supports are arranged between the stator adjusting support plate and the second stator end plate. A buffer structure is arranged on the flexible support, and the two flexible supports are symmetrically arranged.

[0005] Preferably, screw openings are provided on the first stator end plate, the connecting channel steel, and the second stator end plate, and the inner circumference of the screw openings is fixed to the wind turbine tower wall through fasteners.

[0006] Preferably, an external connection plate is connected to the side of the second stator end plate away from the connecting channel steel, and one end of the flexible support is fixed to the external connection plate.

[0007] Preferably, the cross-section of the flexible support is a C-shaped structure, and an angle steel is connected between the other end of the flexible support and the stator adjusting support plate. The angle steel is designed in an L-shaped structure.

[0008] Preferably, the buffer structure includes a buffer cylinder filled with hydraulic oil inside. An inner plug is adaptively arranged inside the buffer cylinder. One side of the inner plug is connected to a pressure column passing through the buffer cylinder. A liquid guide pipe is arranged on one side of the buffer cylinder, and both ends of the liquid guide pipe are respectively communicated with the upper half and the lower half of the buffer cylinder.

[0009] Preferably, the buffer cylinder and the pressing column are respectively fixed to both inner side walls of the flexible support, and a plurality of springs are arranged inside the buffer cylinder.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. Through the design of fixing the first stator end plate, the connecting channel steel and the second stator end plate to the wall of the wind turbine tower, and cooperating with the design that the stator adjusting support plate is not fixed to the tower wall, and then through the action of the flexible support between the stator adjusting support plate and the second stator end plate, when strong wind or earthquake is received, the flexible support has certain flexibility and elastic deformation ability, realizing the effect of cooperating with the fluctuations at the connection, and solving the problem of poor compatibility between the installation bracket and the flexible connection.

[0012] 2. The present utility model also realizes the buffer protection effect on the flexible support through the structural cooperation of the buffer cylinder, the inner plug and the pressing column, and the hydraulic oil filled inside the buffer cylinder, through the design of the communication structure of the liquid guide pipe on both sides of the inner plug and the buffer cylinder, and the self-elastic force of the spring. When a relatively large external force is received, the pressing column will move, cooperate with the movement of the inner plug, generate a squeezing force on the hydraulic oil, enable the hydraulic oil to flow, and cooperate with the restriction of the flow rate to generate a damping effect, avoiding the situation that the flexible support is suddenly subjected to a large external force and causing excessive deformation and fracture, and further solving the problem that the flexible support is easily damaged due to sudden excessive deformation.

[0020] As shown Figures 1 to 5 in the figure, a stator mounting bracket assembly according to the present utility model includes a first stator end plate 1, a connecting channel steel 2, and a second stator end plate 3. Threaded openings are provided on the first stator end plate 1, the connecting channel steel 2, and the second stator end plate 3. The inner circumference of the threaded openings is fixed to the wind turbine tower wall through fasteners, so that it is horizontally fixed to the wind turbine tower wall. The two ends of the connecting channel steel 2 are respectively the first stator end plate 1 and the second stator end plate 3. The first stator end plate 1 and the second stator end plate 3 are fixedly connected to the ends of the connecting channel steel 2. A stator adjusting support plate 4 is provided on one side of the second stator end plate 3. Brackets 5 are connected to one side of both the stator adjusting support plate 4 and the first stator end plate 1. The fixed positions of the brackets 5 are designed as a structure with two semi-circular inward concavities to facilitate clamping the circuit. The stator adjusting support plate 4 is not fixed to the wind turbine tower wall.

[0021] In an embodiment of the present utility model, in order to adapt to the fluctuations and swaying at the connection during soft connection, two flexible supports 6 are provided between the stator adjusting support plate 4 and the second stator end plate 3. The two flexible supports 6 are symmetrically arranged. The flexible supports 6 are made of a material with elastic deformation. An external connection plate 8 is connected to the side of the second stator end plate 3 away from the connecting channel steel 2. The external connection plate 8 is fixed to one end of the flexible support 6. The cross-section of the flexible support 6 is a C-shaped structure. An angle steel 9 is connected between the other end of the flexible support 6 and the stator adjusting support plate 4. The angle steel 9 is designed in an L-shaped structure.

[0022] In an embodiment of the present utility model, the flexible support 6 has a certain elastic deformation ability. However, when suddenly subjected to excessive force, it is likely to break due to excessive deformation. For this point, a buffer structure 7 is provided on the flexible support 6. The buffer structure 7 includes a buffer cylinder 701, an inner plug 702, a pressure column 703, a liquid guide pipe 704, and a spring 705. The buffer cylinder 701 is filled with hydraulic oil. An inner plug 702 is adaptively arranged inside the buffer cylinder 701. One side of the inner plug 702 is connected to a pressure column 703 passing through the buffer cylinder 701. The buffer cylinder 701 and the pressure column 703 are respectively fixed to the two inner side walls of the flexible support 6. A liquid guide pipe 704 is provided on one side of the buffer cylinder 701. The two ends of the liquid guide pipe 704 are respectively communicated with the upper half and the lower half of the buffer cylinder 701. A plurality of springs 705 are arranged inside the buffer cylinder 701. The two ends of the springs 705 are respectively fixed to the inner plug 702 and the inner bottom of the buffer cylinder 701.

[0023] Working principle: This embodiment provides a stator mounting bracket assembly. During use, the first stator end plate 1, the connecting channel steel 2, and the second stator end plate 3 are fixed to the wind turbine tower wall, and then the circuit is fixed to the bracket 5 in cooperation with an external fixing seat, and then it can be used.

[0024] When under strong wind or earthquake conditions, due to the design of the flexible connection, fluctuations will occur at the flexible connection. At this time, the flexible support 6 will deform accordingly. When the deformation is too violent and rapid, the speed of the pressure column 703 descending or ascending will be restricted by the flow rate of the hydraulic fluid inside the buffer cylinder 701, producing a damping effect, achieving a buffer protection effect, preventing the flexible support 6 from breaking, and extending the service life.

Those of ordinary skill in the art can easily understand the spirit of the present utility model based on the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of the present utility model, they are within the protection scope of the present utility model.
