[0002] As the global demand for clean energy grows, wind power generation, as a sustainable way of obtaining energy, plays an increasingly important role in the energy field. As a key device for converting wind energy into electrical energy, the performance and assembly structure of wind turbines directly affect the efficiency and cost of power generation.

[0003] Compared with horizontal axis wind turbines, vertical axis wind turbines have the advantages of being insensitive to changes in wind direction, not requiring complex windward adjustment mechanisms, and having simple blade designs. They have unique application value in some complex terrain and distributed power generation scenarios. However, there are still many problems with the assembly structure of vertical axis wind turbines.

[0008] A connecting groove is provided in the outer concave groove A of the bowl-shaped sleeve, one end of the tensioning clip passes through the connecting groove and extends into the interior of the bowl-shaped sleeve. There are two tensioning clips, which are symmetrically distributed with the bowl-shaped sleeve as the center, and the surfaces of the two tensioning clips are attached to the surface of the stator core.

[0009] A gap is provided between the bottom end of the curved hook and the auxiliary hook end, a rubber base pad is movably abutted in the gap, an insertion tip is provided on the upper surface of the rubber base pad, a protruding end is provided at the bottom of the inner arc surface of the rubber base pad, and the outer arc surface of the protruding end is movably engaged with the concave groove B.

[0010] The inner arc surface of the embracing groove is movably connected with a supporting ring, and the lower surface of the supporting ring is provided with a protruding end, and the lower surface of the protruding end is placed on the surface of the tensioning and relaxing clamping plate. A sealing ring is provided in the gap between the supporting ring and the concave groove A.

[0011] The sealing ring is matched with the internal stator core, the upper surface of the supporting ring platform is provided with an inner concave surface, one end of the inner concave surface is provided with an insert block, and one end of the insert block is placed on the top of the stator core.

[0012] The inner arc surface of the plug block is movably connected with a fixed sleeve seat, the lower surface of the fixed sleeve seat is provided with a U-shaped end, the outer arc surface of the U-shaped end is placed on the stator core, the middle part of the fixed sleeve seat is provided with an annular body, and a spring is fixedly installed on the lower surface of the annular body.

It not only supports the stator core in the vertical direction, but also further constrains the movement space of the stator core in the horizontal direction. Whether the generator is started, stopped, or continuously running at different wind speeds, the rubber base pad can cooperate with the tension and relaxation of the card plate and other components to comprehensively ensure the stability of the stator core and ensure that the generator is always in an efficient and stable operating state.

[0017] 2. The structure of the supporting ring also becomes concave. This deformation process effectively compresses the space of the stator core in the bowl-shaped kit, so that part of the gas in the bowl-shaped kit is discharged. As the gas is discharged, a semi-sealed structure is gradually formed between the bowl-shaped kit and the stator core. This semi-sealed structure not only further reduces the risk of external impurities entering the generator, but also can regulate the internal air pressure to a certain extent, so that the generator can maintain stable operation under different working conditions.

[0018] 3. The movement range of the stator core is further controlled by the fixed sleeve, and the stator core is more strictly constrained in the vertical direction to ensure that there will be no displacement deviation in the up and down directions during the operation of the generator. It can also effectively prevent various faults caused by axial movement of the rotor shaft. When the generator is in long-term operation, the various components work together to continuously ensure the stable operation of the generator. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the present invention includes a generator rotor shaft 1, a flange 2 is fixedly sleeved on the outer side of one end of the generator rotor shaft 1, a generator upper cover 3 is arranged below the flange 2, the generator upper cover 3 is sleeved on the outer side of the generator rotor shaft 1, a generator lower cover 4 is placed below the generator upper cover 3, a generator casing 5 is fixedly installed between the generator upper cover 3 and the generator lower cover 4, the generator rotor shaft 1 is rotatably connected to the generator upper cover 3 and the generator lower cover 4 through a bearing 6, a stator core 7 is sleeved on the inner arc surface of the generator casing 5, and the stator The outer arc surface of the iron core 7 is sleeved with a receiving component 8, and the receiving component 8 includes a bowl-shaped sleeve 81 sleeved on the outer arc surface of the stator iron core 7, and the middle section of the outer arc surface of the bowl-shaped sleeve 81 is provided with an embracing groove 811, and the top of the outer arc surface of the bowl-shaped sleeve 81 is provided with a concave groove A812, and the side of the bowl-shaped sleeve 81 close to the embracing groove 811 is provided with an auxiliary hook end 813, and one end of the auxiliary hook end 813 faces the bottom of the bowl-shaped sleeve 81, and the bottom of the outer arc surface of the bowl-shaped sleeve 81 is provided with a concave groove B814, and the concave groove B814 is symmetrically distributed with the concave groove A812.

[0029] The generator casing 5 is the basic supporting structure of the entire generator, which is usually made of high-strength metal material and has good compression and deformation resistance. Inside the casing, the stator core 7 is tightly combined with the generator casing 5 through the receiving assembly 8 to ensure that no displacement occurs during the operation of the generator. The generator upper cover 3 and the generator lower cover 4 are respectively installed at the top and rear end of the generator casing 5. The generator upper cover 3 mainly plays a protective and shielding role to prevent debris from falling into the generator and affecting power generation. The generator lower cover 4 further closes the generator structure and provides installation space for some auxiliary equipment, such as junction boxes.

[0030] However, if the welding joints are poorly welded and the bolt connections do not reach the specified torque, the connection between the stator core 7 and the casing will easily loosen under long-term vibration and wind impact, which will cause the stator core 7 to shake. On the other hand, during the long-term operation of the generator, the generator is frequently started and stopped, and subjected to alternating stress caused by wind of different intensities, which will gradually loosen the originally firm connection, thereby wrapping the entire stator core 7 through the receiving assembly 8.

[0031] like Figure 2 , Figure 4 and Figure 6 As shown, the lower surface of the auxiliary hook end 813 is movably connected with a mounting guide ring 82, and the lower surface of the mounting guide ring 82 is provided with a bent hook bottom end 821, one end of the bent hook bottom end 821 is clamped to the bottom surface of the auxiliary hook end 813, and the upper surface of the mounting guide ring 82 is an outward expansion section, and tensioning clamps 822 are provided on both sides of the inner arc surface of the mounting guide ring 82, and a connecting groove 815 is opened in the outer concave groove A812 of the bowl-shaped kit 81.

[0032] During the specific installation, for the installation method used to prevent the stator core 7 from shaking, first, the bowl-shaped sleeve 81 plays an important preliminary positioning role. It has an inner arc surface made of rubber material. When no external force is applied, when the bowl-shaped sleeve 81 contacts the outer periphery of the stator core 7, due to the characteristics of the rubber material, friction will be generated between the stator core 7, thereby being able to preliminarily position the stator core 7 and ensure its relative position is stable during the initial installation stage.

[0033] However, in order to achieve a full and tight fit between the surface of the bowl-shaped kit 81 and the stator core 7, it is necessary to further utilize the installation guide ring 82. After the preliminary positioning of the bowl-shaped kit 81, the installation guide ring 82 is snap-fitted to the bottom surface of the auxiliary hook end 813 on the periphery of the bowl-shaped kit 81. A relaxation clamping plate 822 is installed on the inner arc surface of the installation guide ring 82. When the installation guide ring 82 is installed in place, the relaxation clamping plate 822 extends from the connection groove 815 of the bowl-shaped kit 81 into its interior. Due to the elastic property of the relaxation clamping plate 822, when it comes into contact with the surface of the stator core 7, it will bend and deform, and then tightly press against the surface of the stator core 7. Under the combined abutting action of the two relaxation clamping plates 822 on both sides, an effective constraint in the left and right directions of the stator core 7 is formed, preventing the stator core 7 from shaking in the left and right directions and ensuring the stability of the stator core 7 in the entire generator assembly structure.

[0034] As Figure 5 shown, one end of the relaxation clamping plate 822 penetrates into the connection groove 815 and extends into the interior of the bowl-shaped kit 81. The number of relaxation clamping plates 822 is two, and they are symmetrically distributed with the bowl-shaped kit 81 as the center. The surfaces of the two relaxation clamping plates 822 are in contact with the surface of the stator core 7. There is a gap between the bottom end of the hook 821 and the auxiliary hook end 813, and a rubber bottom pad 83 is movably abutted in the gap. The upper surface of the rubber bottom pad 83 is provided with an insertion tip 831, and the bottom of the inner arc surface of the rubber bottom pad 83 is provided with a protruding end 832. The outer arc surface of the protruding end 832 is movably snap-fitted with the concave groove B814.

[0035] To further improve the installation stability and prevent the clamping between the auxiliary hook end 813 and the bottom end of the hook 821 from loosening, a rubber bottom pad 83 is inserted into the gap between the two. The upper surface of the rubber bottom pad 83 is designed with an insertion tip 831, and the insertion tip 831 has a structure with a gradually increasing bottom end. During the process of slowly inserting the rubber bottom pad 83 into the gap, as the insertion depth increases, the gradually increasing volume of the insertion tip 831 will strongly squeeze the bottom end of the hook 821. This squeezing effect makes the connection between the auxiliary hook end 813 and the bottom end of the hook 821 more tight, thus forming a reliable fixation and effectively restricting the loosening of the installation guide ring 82.

[0036] It is worth mentioning that the rubber bottom pad 83 is made of soft rubber. On the one hand, during the operation of the generator, vibration will inevitably occur. The rubber bottom pad 83 made of soft rubber can play a good buffering role, so that the vibration will not be directly transmitted to the stator core 7, thus providing reliable protection for the stator core 7 and avoiding problems such as wear and deformation caused by long-term vibration, and extending the service life of the stator core 7. On the other hand, the rubber bottom pad 83 is placed at the bottom of the stator core 7. It not only supports the stator core 7 in the vertical direction, but also further restricts the moving space of the stator core 7 in the horizontal direction. Whether the generator starts, stops, or operates continuously at different wind speeds, the rubber bottom pad 83 can cooperate with components such as the relaxation clamping plate 822 to ensure the stability of the stator core 7 in all directions, and ensure that the generator is always in an efficient and stable operating state.

[0037] As Figure 4 and Figure 5 shown, a support ring platform 9 is movably clamped to the inner arc surface of the surrounding groove 811. An extension end 901 is provided on the lower surface of the support ring platform 9. The lower surface of the extension end 901 is placed in contact with the surface of the relaxation clamping plate 822. A sealing ring 10 is provided at the gap between the support ring platform 9 and the concave groove A812. The sealing ring 10 is adapted to the internal stator core 7. An inner concave surface 902 is provided on the upper surface of the support ring platform 9. One end of the inner concave surface 902 is provided with an insertion block 903. One end of the insertion block 903 is placed on the top of the stator core 7.

[0038] During the normal use of the generator, a space is reserved in the gap between the two relaxation clamping plates 822 and the surrounding groove 811 to cleverly install the support ring platform 9 therein. The tail end of the support ring platform 9 is designed as an extension end 901, whose bottom surface is in close contact with the surface of the relaxation clamping plate 822, and its unique "L" - shaped structure extends to the top surface of the installation guide ring 82 and is placed on the top of the stator core 7. The insertion block 903 at one end of the support ring platform 9 is specially designed to facilitate clamping with the rectangular groove 114 opened on the fixed socket 11. Through this clamping method, the fixed socket 11 at the top can be tightly connected with the support ring platform 9 to form a whole, greatly enhancing the stability of the top structure.

[0039] In addition, the top of the support ring 9 is set as an inner concave surface 902. In the initial state without being pressed by external force, the inner concave surface 902 is upwardly arched and has a certain elastic potential energy. When subjected to a downward pressing force, the inner concave surface 902 will move toward the bowl-shaped sleeve 81, and its structure will also become concave. This deformation process effectively compresses the space of the stator core 7 in the bowl-shaped sleeve 81, so that part of the gas in the bowl-shaped sleeve 81 is discharged. As the gas is discharged, a semi-sealed structure is gradually formed between the bowl-shaped sleeve 81 and the stator core 7. This semi-sealed structure not only further reduces the risk of external impurities entering the interior of the generator, but also can regulate the internal air pressure to a certain extent, so that the generator can maintain stable operation under different working conditions. At the same time, the semi-sealed structure also helps to reduce air friction between internal components, reduce energy loss, and improve the power generation efficiency of the generator. While the inner concave surface 902 is pressed downward, the protruding end 901 will also press downward against the surface of the tension and relaxation card 822, thereby stabilizing the connectivity of the tension and relaxation card 822.

[0040] like Figure 2 , Figure 3 and Figure 4 As shown, the inner arc surface of the plug block 903 is movably connected with the fixed sleeve 11, the lower surface of the fixed sleeve 11 is provided with a U-shaped end 111, the outer arc surface of the U-shaped end 111 is placed on the stator core 7, the middle part of the fixed sleeve 11 is provided with an annular body 112, the lower surface of the annular body 112 is fixedly installed with a spring 113, the end of the spring 113 away from the annular body 112 abuts on the outer expansion section of the surface of the mounting guide ring 82, a rectangular groove 114 is provided between the annular body 112 and the U-shaped end 111, the inner arc surface of the rectangular groove 114 abuts with one end of the plug block 903, the top of the fixed sleeve 11 is provided with an extrusion portion 115, the top of the extrusion portion 115 is provided with a contact end 116, the contact end 116 is in contact with the outer arc surface of the generator rotor shaft 1, and the contact end 116 is a ring-shaped structure.

[0041] At the same time, the bottom end of the fixed sleeve 11 is designed as a U-shaped end 111, which plays a key limiting role in the entire structural system. Its lowest surface is just placed on the stator core 7. When the support ring 9 moves downward due to external force, the U-shaped end 111 at the bottom will slowly approach the top of the stator core 7 until the two are tightly fitted. This fitting process further controls the movement range of the stator core 7, and imposes more stringent constraints on the stator core 7 in the vertical direction, ensuring that there will be no displacement deviation in the up and down directions during the operation of the generator, providing a solid mechanical structure foundation for the stable electromagnetic conversion of the generator.

[0042] Meanwhile, the top annular body 112 plays a role in controlling the compression of the control spring 113 throughout the system. By regulating the degree of compression of the spring 113, the top annular body 112 can effectively contact and affect the deformation of the concave surface 902. During this process, the extrusion part 115 will closely fit the outer arc surface of the generator rotor shaft 1, and use its good fit to provide a stable radial support force for the generator rotor shaft 1, ensuring the stability of the rotor shaft during high-speed rotation. The top contact end 116 will be clamped into the gap of the generator rotor shaft 1. This clamping method not only enhances the connection stability between the generator rotor shaft 1 and the fixed socket 11, but also effectively prevents various faults caused by the axial movement of the rotor shaft. During the long-term operation of the generator, each component works together to continuously ensure the stable operation of the generator, reduce energy loss and equipment failures caused by problems such as component loosening and displacement, and further improve the overall performance and reliability of the generator, enabling it to efficiently and stably convert wind energy into electrical energy under various complex working conditions.
