[0030] Example 1

[0031] like Figures 1 to 3As shown, a split-flap generator base is disclosed, including a ring-shaped base body, which is composed of a plurality of split-flap bodies 1 assembled and spliced ​​together; a flange plate 2 is provided at the end face of each split-flap body 1; the flange plates 2 on adjacent split-flap bodies 1 are connected by bolts 3; threaded holes connected to the generator and an adjustment part 8 for adjusting the position of the base body relative to the generator are provided at both ends of the flange plate 2.

[0032] In this embodiment, the main body of the base is composed of a plurality of petal bodies 1 assembled and spliced ​​together, and the petal bodies 1 are specifically in the shape of a circular ring. Thus, they are fastened to the fixed base. In order to facilitate the connection between the petal bodies 1, a flange plate 2 is provided at the end face of each petal body 1. When the base is installed, the connected petal bodies 1 are connected by bolts 3, specifically, the flange plate 2 is fixedly connected by bolts 3. At the same time, threaded holes connected to the generator are provided at both ends of the flange plate 2. When the generator is installed, the threaded holes are aligned and installed on the main body of the base. In the actual installation process, it is inevitable that there are slight deviations in the positions of adjacent petal bodies. Therefore, an adjustment part 8 for adjusting the relative positions of the connected petal bodies is provided on the flange plate 2. By adjusting the adjustment part 8, the positions between the connected petal bodies 1 are adjusted, so that the connected petal bodies 1 in the combined base are accurately aligned. Thereby, the installation efficiency and installation accuracy of the generator are greatly improved.

[0033] Example 2

[0034] Disclosed is a split-flap generator base, comprising a ring-shaped base body, which is formed by combining and splicing a plurality of split-flap bodies 1; a flange plate 2 is provided at the end face of each split-flap body 1; the flange plates 2 on adjacent split-flap bodies 1 are connected by bolts 3; threaded holes connected to the generator and an adjustment portion 8 for adjusting the position of the base body relative to the generator are provided at both ends of the flange plate 2.

[0035] The difference between this embodiment and Embodiment 1 is that the number of the petal bodies 1 can be two or more. In this embodiment, in order to improve the installation efficiency between the petal bodies 1 and ensure the stability of the base, the number of the petal bodies 1 is specifically two.

[0036] In order to further enhance the connection stability between the flange plates 2, the connection bolts connecting the flange plates 2 are evenly arranged at positive and negative intervals. Compared with the one-way arrangement, the connection bolts are arranged at positive and negative intervals, and the connection force between the flange plates 2 connected by the connection bolts is stronger, and the connection between the flange plates 2 is more stable.

[0037] Example 3

[0038] Disclosed is a split-flap generator base, comprising a ring-shaped base body, which is formed by combining and splicing a plurality of split-flap bodies 1; a flange plate 2 is provided at the end face of each split-flap body 1; the flange plates 2 on adjacent split-flap bodies 1 are connected by bolts 3; threaded holes connected to the generator and an adjustment portion 8 for adjusting the position of the base body relative to the generator are provided at both ends of the flange plate 2.

[0039] The difference between this embodiment and embodiment 1 is that the generator will inevitably vibrate during operation, which will cause the flange plate 2 connected to the generator to deform under stress. To prevent the flange plate 2 from deforming under stress, a reinforcing rib 4 can be provided on the outer wall of the petal body 1, and the other end of the reinforcing rib 4 is connected to the flange plate.

[0040] In order to facilitate the alignment of the petal body and thus improve the installation efficiency of the petal body 1, positioning holes and cylindrical pins adapted to the positioning holes are respectively provided on the two adjacent flange plates 2. Through this design, the alignment efficiency during the installation of the petal body is improved, thereby improving the installation efficiency of the base. Anti-loosening washers are also provided between adjacent flange plates 2 to further improve the connection stability between the petal bodies.

[0041] In order to facilitate the installation of the stator core on the generator, a guide groove is provided on the inner wall of the lobed body 1, and the stator core is installed in the guide groove.

[0042] Example 4

[0043] Disclosed is a split-flap generator base, comprising a ring-shaped base body, which is formed by combining and splicing a plurality of split-flap bodies 1; a flange plate 2 is provided at the end face of each split-flap body 1; the flange plates 2 on adjacent split-flap bodies 1 are connected by bolts 3; threaded holes connected to the generator and an adjustment portion 8 for adjusting the position of the base body relative to the generator are provided at both ends of the flange plate 2.

[0044] The difference between this embodiment and the above embodiment is that a mounting plate 5 is further provided at one end of the petal body 1, and the mounting plate 5 is provided along the circumferential direction of the petal body 1. To facilitate the lifting of the machine base, a lifting hole 6 can also be provided on the mounting plate 5. The lifting hole 6 is connected to the lifting equipment to realize the automatic transportation of the petal body 1.

[0045] Example 5

[0046] Disclosed is a split-flap generator base, comprising a ring-shaped base body, which is formed by combining and splicing a plurality of split-flap bodies 1; a flange plate 2 is provided at the end face of each split-flap body 1; the flange plates 2 on adjacent split-flap bodies 1 are connected by bolts 3; threaded holes connected to the generator and an adjustment portion 8 for adjusting the position of the base body relative to the generator are provided at both ends of the flange plate 2.

[0047] The difference between this embodiment and the above-mentioned embodiment is that the adjustment portion 8 includes a mounting block connected to the flange plate 2 and an adjusting bolt arranged on the mounting block.

[0048] The mounting blocks can be specifically arranged on both sides of the flange plate, or can be arranged above and below the flange plate. The adjustment principle of the adjustment part 8 is to adjust the force between the bolts and the flange plate by adjusting different adjustment bolts. When the contact force between the left adjustment bolt and the flange plate increases, the flange plate, that is, the petal body, naturally shifts to the left.

[0049] Similarly, an adjustment block may be provided on the mounting block, and the relative displacement of the petal body may be adjusted by the adjustment block, thereby achieving the purpose of adjusting the position of the base and the generator.

[0050] Example 6

[0051] Disclosed is a split-flap generator base, comprising a ring-shaped base body, which is formed by combining and splicing a plurality of split-flap bodies 1; a flange plate 2 is provided at the end face of each split-flap body 1; the flange plates 2 on adjacent split-flap bodies 1 are connected by bolts 3; threaded holes connected to the generator and an adjustment portion 8 for adjusting the position of the base body relative to the generator are provided at both ends of the flange plate 2.

[0052] The difference between this embodiment and the above-mentioned embodiment is that a water flow channel is provided inside the arc-shaped wall of the petal body 1, and a water inlet and a water outlet connected to the water flow channel are provided on the outer wall. Since the stator core is installed on the inner wall of the petal body 1, the generator will generate heat energy during the power generation process, thereby causing the temperature of the petal body 1 to rise. Therefore, by providing a water flow channel inside the petal body 1, cooling water flows in from the water inlet and flows out from the water outlet. During the flow process, the cooling water will absorb the heat energy on the petal body 1 under the action of heat transfer, thereby cooling the petal body 1.

[0053] When there are two petal bodies 1 on the base, a connecting pipe 7 can be arranged between the two petal bodies 1. One end of the connecting pipe 7 is connected to the water outlet of one of the petal bodies 1, and the other end is connected to the water inlet of the other petal body 1.

Obviously, the above-described embodiments of the utility model are merely examples for clearly illustrating the utility model, and are not limitations on the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here.
