[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 This utility model provides a wind turbine housing support base, including a base assembly 1, a generator assembly 2 and a wind turbine assembly 3. The generator assembly 2 is disposed on the base assembly 1, the wind turbine assembly 3 is disposed on the generator assembly 2, the base assembly 1 is provided with a buffer assembly 4 and a snap-fit ​​assembly 5, and the base assembly 1 and the generator assembly 2 are connected by a limiting assembly 6.

[0026] The base assembly 1 includes a support rod 11, and an insertion hole is provided at the upper end of the support rod 11. The generator assembly 2 includes a generator housing 21 and a connecting rod 23. The generator housing 21 is located above the support rod 11, and the connecting rod 23 is located on the generator housing 21. A connecting plate 24 is provided on the connecting rod 23. Both the connecting rod 23 and the connecting plate 24 are located in the insertion hole.

[0027] The snap-fit ​​assembly 5 includes an A electrically controlled telescopic rod 51 and a snap-fit ​​component 52. An installation groove is provided in the insertion hole. The A electrically controlled telescopic rod 51 is set in the installation groove. The snap-fit ​​component 52 is set at the telescopic end of the A electrically controlled telescopic rod 51. The snap-fit ​​component 52 is snap-fitted with the connecting plate 24.

[0028] Specifically, in use, wind power generation can be achieved by assembling the base assembly 1, generator assembly 2, and wind turbine assembly 3. During assembly, in order to achieve stable and rapid assembly, the support rod 11 is first placed vertically by a crane. Then, the generator assembly 2 and wind turbine assembly 3 are combined, and the generator assembly 2 is lifted directly above the support rod 11. The connecting rod 23 is placed in the insertion hole. At this time, both the connecting rod 23 and the connecting plate 24 slide in the insertion hole. When the connecting plate 24 slides, it will press the snap-fit ​​52 into the mounting groove, so that the connecting plate 24 can move below the snap-fit ​​52. After the connecting rod 23 is fully inserted, the A-type electric telescopic rod 51 is remotely activated, which can drive the snap-fit ​​52 to move. Then, the snap-fit ​​52 can be used to snap the connecting plate 24, so that the generator assembly 2 can be initially and stably set up.

[0029] In this embodiment, the base assembly 1 further includes a fixing member 12, which is disposed on the support rod 11 and is connected to the ground.

[0030] Specifically, in order to ensure that the support rod 11 can be set stably, a fixing member 12 can be set at the lower end of the support rod 11. In use, a mounting base can be pre-set on the ground, and the fixing member 12 can be welded to the mounting base or detachably connected by bolts, so that the support rod 11 can be placed stably vertically.

[0031] In this embodiment, the generator assembly 2 further includes a power conversion module 22, which is disposed inside the generator housing 21. The input end of the power conversion module 22 is connected to the wind turbine assembly 3. The wind turbine assembly 3 includes a drive wheel 31 and blades 32. The drive wheel 31 is connected to the output end of the power conversion module 22. Multiple blades 32 are provided, and all multiple blades 32 are disposed on the drive wheel 31.

[0032] Specifically, in order to generate electricity when the wind turbine assembly 3 rotates, the drive wheel 31 can be connected to the input end of the power conversion module 22, and the blade 32 can be connected to the drive wheel 31, thereby enabling power generation.

[0033] Furthermore, blade 32 adopts a curved airfoil design similar to an airfoil. When airflow passes over it, the pressure difference between the upper and lower surfaces of blade 32 due to the velocity difference creates a Bernoulli effect, generating lift to drive blade 32 to rotate. Even at a low rotational speed, the giant blade, which is over 80 meters long, can still capture powerful torque. Blade 32 exhibits a tapering torsional shape from root to tip, with different aerodynamic parameters used in each section to reduce drag while maximizing lift efficiency. The three-blade layout can maintain dynamic balance and reduce structural losses caused by gravity.

[0034] Furthermore, the high-speed rotating generator rotor drives the copper winding coil to move in a strong magnetic field. According to Faraday's law of electromagnetic induction, the coil cuts the magnetic field lines to generate alternating current. A typical permanent magnet generator can achieve an efficiency of up to 98%. In operation, the blade angle can be dynamically adjusted by 32 degrees through the pitch system. When the wind speed exceeds 25 m / s, the blades are forced to feather and the generator stops. At the same time, the inverter stabilizes the output current frequency.

[0035] In this embodiment, the buffer assembly 4 includes a buffer plate 41, a damper 42, a rectangular A member 43, a rectangular B member 44, and an elastic member 45. The buffer plate 41 is disposed in the insertion groove, the rectangular B member 44 is disposed on the lower inner wall of the insertion groove, the rectangular A member 43 is disposed on the buffer plate 41, the damper 42 is disposed on the lower inner wall of the insertion groove, and the telescopic end of the rectangular A member 43 is connected to the rectangular A member 43. The elastic member 45 is hinged to the rectangular A member 43 and the buffer assembly 4.

[0036] Specifically, during installation, to prevent the connecting rod 23 from directly impacting the bottom of the insertion hole, a buffer plate 41 can be slidably installed inside the insertion hole. A rectangular member 43 is installed at the lower end of the buffer plate 41, and a rectangular member 44 is installed at the bottom of the insertion hole. The elastic member 45 is hinged to the rectangular member 43 and the rectangular member 44 respectively, and a damper 42 is installed at the lower end of the rectangular member 43. During installation, the connecting rod 23 will push the buffer plate 41 downward. At this time, the impact can be avoided by the contraction of the elastic member 45. When the elastic member 45 rebounds, the rebound rate can be controlled by the damper 42 to prevent the connecting rod 23 from rising rapidly.

[0037] In this embodiment, a connecting plate 24 is provided on the connecting rod 23, and a shock-absorbing pad 25 is provided on the connecting plate 24.

[0038] Specifically, during use, a connecting plate 24 can be installed on the connecting rod 23, and a shock-absorbing pad 25 can be installed at the lower end of the connecting plate 24 to prevent the connecting plate 24 from colliding directly with the expansion plate 65.

[0039] In this embodiment, the limiting component 6 includes a lead screw 61, a ratchet 62, a ratchet tooth 63, a B-type electrically controlled telescopic rod 64, and an extension plate 65. The lead screw 61 is mounted on the support rod 11 and passes through the shock-absorbing pad 25 and is threadedly connected to the connecting plate 24. The ratchet tooth 62 is mounted on the lead screw 61. The extension plate 65 is mounted on the support rod 11. The B-type electrically controlled telescopic rod 64 is mounted on the extension plate 65. The ratchet tooth 63 is mounted on the support rod 11 and engages with the ratchet tooth 62. The ratchet tooth 63 and the B-type electrically controlled telescopic rod 64 are hinged together.

[0040] Specifically, during installation, when the connecting plate 24 moves downward, it will drive the lead screw 61 to rotate, which in turn drives the ratchet 62 to rotate. After the generator assembly 2 is installed, the lead screw 61 stops rotating, which in turn stops the ratchet 62. At this time, the ratchet 63 can engage the ratchet 62 to prevent the lead screw 61 from reversing. When it is necessary to remove the generator assembly 2, the B-controlled telescopic rod 64 can be retracted to release the ratchet 63 from engaging the ratchet 62, at which point the generator assembly 2 can be removed.

[0041] The working principle and usage process of this utility model are as follows: During installation, the base assembly 1 can be stably set up using a crane. Then, the fixing member 12 can be connected to the ground or a pre-installed mounting component on the ground, thus ensuring the support rod 11 is stably set up. Next, the generator assembly 2 and the wind turbine assembly 3 can be connected, the drive wheel 31 can be connected to the input end of the power conversion module 22, and the drive wheel 31 can be connected to the three blades 32. Then, the generator housing 21 can be lifted by a crane to directly above the support rod 11. The connecting rod 23 can be placed inside the insertion hole. When the connecting rod 23 moves within the insertion hole, it can be engaged by the locking assembly. 5. The connecting plate 24 is snapped into place, so that the generator housing 21 can be initially and stably connected to the support rod 11. During installation, in order to prevent the connecting rod 23 from directly impacting the bottom of the insertion hole, a snap-fit ​​component 5 can be set in the insertion hole. During installation, the snap-fit ​​component 5 can buffer the impact force of the connecting rod 23, thereby protecting the electronic components inside the generator housing 21. During installation, the limiting component 6 can be stably connected to the connecting plate 24, so that the generator housing 21 can be further stably connected to the support rod 11, thereby preventing the generator housing 21 from shaking significantly during subsequent use, which would affect the power generation efficiency.

[0042] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
