Problems solved by technology
When the blade rotates at high speed, the stability is poor. When the blade rotates, because the wind speed of the upwind side and the downwind side of the blade are different, the pressure of the airflow acting on the two sides of the blade is different, and there is a pressure difference, which affects the stability of the blade; at the same time, the blade The centrifugal force increases with the speed of the blade, which increases the bending stress of the blade and makes the stability of the blade worse.
Although the current blades are mostly made of light, tough and high-strength materials, the length of the blades still cannot meet the needs of large power generation

Embodiment
[0010] Example: such as figure 1 As shown, the wind power generator with the main shaft inclined-pulled blade structure includes three blades 1 evenly distributed on the swivel 2 at 120°, and the main shaft 4 is installed at the center of the swivel 2, and one end of the main shaft 4 is fixed to the wind power generator. In the case, one end extends horizontally forward, and a rotatable rotor 5 is installed at the front end of the main shaft 4, and each blade 1 to the rotor 5 is connected with reinforcing ribs 3, and adjacent blades 1 are also connected with reinforcing ribs 3 .
[0011] The joint of the reinforcing rib 3 is preferably located at the center of the blade 1, and may also be arranged at the outer end of the blade 1, or both of the aforementioned situations may be arranged at the same time. The number of reinforcing ribs 3 at each joint can be increased according to actual conditions.
[0012] A connection node 6 is arranged at the center of each blade 1, and th...

The invention belongs to the field of wind power utilization and particularly relates to a wind driven generator with the blade structure cable-stayed by the spindle. The wind driven generator with the blade structure cable-stayed by the spindle can keep the blade structure stable and comprises three blades which are uniformly distributed on a rotating ring at 120 degrees, the center of the rotating ring is provided with the spindle, one end of the spindle is fixed inside the case of the wind driven generator, the other end of the spindle extends forwards, and the foremost end of the spindle is provided with a rotatable rotor; a reinforcing rib is connected from the center of every blade to the rotor, and one reinforcing rib is connected between every two neighboring blades. The wind driven generator with the blade structure cable-stayed by the spindle is simple in structure, easy to manufacture, convenient to arrange, low in cost, capable enhancing the stability of the blades and increasing the length of the blades, particularly, when rotating at a high speed, can still maintain the stability of the blades, thereby being applicable to product manufacturing and further popularization.
Description
technical field [0001] The wind power generator of the present invention belongs to the field of wind energy utilization, and in particular relates to a wind power generator with a main shaft inclined blade structure maintaining a stable structure of the blades of the wind power generator. Background technique [0002] The power generation of a traditional wind generator mainly depends on the length of its blades, and the length of the blades is affected by many aspects such as manufacturing materials, rotational speed, and wind speed. When the blade rotates at high speed, the stability is poor. When the blade rotates, because the wind speed of the upwind side and the downwind side of the blade are different, the pressure of the airflow acting on the two sides of the blade is different, and there is a pressure difference, which affects the stability of the blade; at the same time, the blade The effect of centrifugal force increases with the speed of the blade, which increase...
