Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wind power generation, in particular to a wind generator. Background Art
[0002] A wind turbine is a mechanical device that converts wind kinetic energy into electrical energy. The first step in this conversion process is for the blades to convert wind energy into mechanical energy. The second step is to transmit this mechanical energy to the generator via a connecting transmission device. The third step is for the generator to convert this mechanical energy into electrical energy for output. Therefore, one of the primary research subjects for energy conversion is the blades. The aerodynamic performance of the blades determines their ability to capture wind and, therefore, the wind turbine's efficiency in utilizing wind energy.
[0003] At present, most domestic wind turbines are horizontal-axis, which mainly include a fan blade structure similar to a windmill. When the wind blows, the fan blades are driven to rotate, thereby converting wind energy into electrical energy. However, it requires a tail rudder or yaw equipment to operate against the wind. Yaw steering takes a certain amount of time, and the wind energy utilization efficiency is low.
[0004] Therefore, a wind turbine is provided to solve the above problems. Utility Model Content

[0007] The beneficial effects of the present invention are as follows: one end of the bracket is fixedly positioned at a desired location, and the vertical blade assembly, under the influence of external wind force, drives the fan main shaft to rotate, thereby directing air passing through the vertical blade assembly to the horizontal blades. Simultaneously, the horizontal blades, under the influence of external wind force and the wind force of the vertical blade assembly, drive the fan main shaft to rotate, and in turn drive the generator main shaft to rotate, thereby improving the efficiency of wind energy utilization.
[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

One end of the support arm is detachably connected to the outer side of the first shaft sleeve, and the other end of the support arm is detachably connected to the vertical blade.
[0011] The beneficial effect of this further solution is that, when subjected to wind force, the vertical blades drive the first sleeve to rotate via the support arm, thereby driving the rotation of the wind turbine main shaft. The rotation plane of the wind rotor composed of multiple vertical blades is parallel to the wind direction, absorbing wind energy from multiple directions and thereby improving wind energy absorption efficiency.
[0012] Furthermore, the cross sections of the vertical blades and the horizontal blades gradually increase in thickness from one end to the other.
[0013] Furthermore, the vertical blades and the horizontal blades are both made of one of fiberglass, carbon fiber, and aluminum alloy.
[0014] The beneficial effect of adopting the above further solution is that the material of the vertical blades and the horizontal blades are one of fiberglass, carbon fiber, and aluminum alloy, which can reduce the weight of the blades and increase the high strength and rigidity of the blades to adapt to extremely harsh conditions and improve the applicability of the device.
[0015] Furthermore, the number of the vertical blade assemblies and the number of the horizontal blades are at least 5.
[0016] Furthermore, the angle between the outer side wall of the vertical blade assembly and the horizontal axis is 45°, and the angle between the outer side wall of the horizontal blade and the vertical axis is 45°.
[0017] Furthermore, it also includes a second shaft sleeve and a support block. The other end of the fan main shaft is covered with a second shaft sleeve, and multiple support blocks are distributed circumferentially along the second shaft sleeve. One end of the support block is fixedly connected to the outer side of the second shaft sleeve. Multiple support blocks are arranged in a one-to-one correspondence with multiple horizontal blades, and the other end of the support block is detachably connected to the corresponding horizontal blade.
[0018] The beneficial effect of adopting the above further solution is that after the horizontal blades are affected by external wind force and the wind force of the vertical blade assembly, the second shaft sleeve is driven to rotate through the support block, thereby improving the utilization rate of wind energy.

[0020] The beneficial effect of adopting the above further solution is that after being acted upon by wind, the multiple fan blades drive the fan main shaft to rotate, thereby guiding the air passing through the vertical blade assembly to flow to the multiple horizontal blades, thereby improving wind energy utilization.
[0021] Furthermore, the number of the fan blades is at least 3. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Specifically, the plurality of vertical blade assemblies 5 may be evenly distributed or unevenly distributed along the circumferential direction of one end of the fan main shaft 4 , preferably evenly distributed.
[0032] Specifically, the circumferential spacing of the plurality of horizontal blades 6 along the other end of the fan main shaft 4 can be uniformly distributed or unevenly distributed, preferably uniformly distributed.

[0034] Specifically, the main shaft of the generator 2 and the main shaft of the wind turbine 4 may be indirectly connected via a coupling 3 or other structures.
[0035] Based on the above scheme, the vertical blade assembly 5 includes a vertical blade 501 and a support arm 502. A first shaft sleeve 503 is provided on one end of the fan main shaft 4.

[0045] The vertical blades 501 and the horizontal blades 6 are made of one of fiberglass, carbon fiber, and aluminum alloy, which can reduce the weight of the blades and increase the strength and rigidity of the blades to adapt to extremely harsh conditions and improve the applicability of the device.

[0047] Specifically, such as Figure 1 As shown, this embodiment includes three vertical blade assemblies 5 and two horizontal blades 6 (not shown in the figure). The staff can set more than five vertical blade assemblies 5 and more than five horizontal blades 6 according to actual conditions.
[0048] Among them, Figure 2 As shown, it includes 6 vertical blade assemblies 5 and 6 horizontal blades 6.

Multiple support blocks 602 are arranged in a one-to-one correspondence with multiple horizontal blades 6, and the other end of the support block 602 is detachably connected to the corresponding horizontal blade 6.
[0051] After being acted upon by external wind and the wind of the vertical blade assembly 5 , the horizontal blade 6 drives the second shaft sleeve 601 to rotate via the support block 602 , thereby improving the utilization rate of wind energy.

[0054] After being acted upon by wind, the plurality of fan blades 7 drive the fan main shaft 4 to rotate, thereby guiding the air passing through the vertical blade assembly 5 to flow toward the plurality of horizontal blades 6, thereby improving the utilization rate of wind energy.
[0055] Specifically, the fan blades 7 may be wave-shaped blades, so that uniform wind force can be generated when the fan blades 7 rotate.
[0056] The circumferential spacing of the plurality of fan blades 7 along the other end of the fan main shaft 4 may be uniformly distributed or unevenly distributed, preferably uniformly distributed.
