Problems solved by technology

[0002] The main working principle of existing wind power or hydroelectric power generation is that external force (water power or wind power) pushes the blade of a rotating impeller to make it rotate to generate electricity. Since the surface of the blade must have an included angle with the external force when it is stressed, That is, the surface of the blade must be made into a slope to convert the external force in the vertical direction into the rotational force in the horizontal direction. Because the angle between the vertical force and the horizontal force is 90°, the best angle to convert the vertical force into a horizontal force is 45°, indicating that only 1/2 of the vertical force can be converted into horizontal force, that is, only half of the force has done useful work, which means

Example Embodiment

[0023] Embodiment 1, in a large-scale unit, it is necessary to use a larger area of ​​the blade 3 to push, preferably a mandatory limit ring 5 is provided on the outer circumference of the support plate 2, and a number of blades are arranged on the inner edge of the mandatory limit ring 5. 3. The matched meshing teeth 51; the tooth height of the meshing teeth 51 is H, then H≤(D1-D2) / 2. The main principle is the same as above, the difference is that when the blade 3 revolves to the free part 43 of the track plate 4 (ie, the small-diameter circular part of the guide groove 41), the outer side of the blade 3 is free from the restriction of the mandatory limit ring 5, so that the The shaft 31 can rotate in the fitting hole 21; when the blade 3 revolves to the work area of ​​the work part 42 of the track plate 4 (ie, the large-diameter circle part of the guide groove 41), it is limited by the guide groove 41. The sub-shaft 31 meshes with the revolving portion 22 on the adapting hol...

Example Embodiment

[0030] In Example 2, 4 groups of 8 blades 3 are arranged between the support plates 2. Under the action of the external wind force, one blade of the first group of blades 3 is located at the 270° position. At this point, the track plate 4 pushes the blades 3 together with the sub-shaft 31 to the position of 270°. At the position of the working part 42 (the far axis, that is, the great circle of the track plate 4), the tapered section of the factor shaft 31 enters the tapered groove of the support plate 2, which limits the rotation of the blade 3. The front of the blade 3 is completely affected by the vertical action of the external force, and the blade 3. The same as facing the wind or facing the water flow, there is no angle between the blade 3 and the external force, 100% of the external force is converted into torque to do work, and there is no energy waste, only the main shaft 1 can be used as the axis to revolve, the torque generated at this point is the largest, and The o...

Example Embodiment

[0031]Embodiment 3, when the main shaft 1 is placed horizontally, when the blade 3 rotates to the work part 42, due to the action of gravity, the blade 3 can automatically fall into the mandatory limit ring 5, when the blade 3 rotates out of the work part, under gravity Under the action, the blade 3 is separated from the mandatory limit ring 5. Therefore, when the device is placed horizontally, the track plate 4 can be eliminated, which further saves the installation and manufacturing cost.

Abstract

The invention relates to the technical field of wind (water) power generation structures, in particular to a wind (water) power generator stressed in the forward direction. The wind (water) power generator comprises a generator spindle. The two ends of the spindle are provided with supporting plates which can rotate integrally with the two ends of the spindle. A plurality of blades are arranged between the two supporting plates. Sub spindles are arranged at the two ends of each blade. The supporting plates are provided with a plurality of matching holes which are in one-to-one correspondence with the blades. The sub spindles penetrate into the corresponding matching holes in the supporting plates. The states of the blades can be switched in the wind wheel rotating process, the blades can only achieve revolution on the rear half of the circumference (namely at the angle of 190-350 degrees) to generate thrust so that an acting area can be formed, the blades can only be rotated automatically on the front half of the circumference (namely at the angle of 10-170 degrees) so that a non-acting area can be formed, the spindle can be rotated under the resultant action to act, and the distance between the blades and the spindle and the sizes of the blades and the spindle can be changed so that the power and torque can be improved. The effective surface area of the blades is larger than that of a traditional impeller, practicability is greatly improved, manufacturing difficulty and production cost are lowered, and the range of the application field of the generator is widened.

Description

technical field [0001] The invention relates to the technical field of wind (water) power generation structures, in particular to a wind (water) power generator with positive force. Background technique [0002] The main working principle of the existing wind or water power generation is that external force (water or wind) pushes the blades of a rotating impeller to rotate to generate electricity. Because the surface of the blade must have an included angle when it is stressed and the external force, That is to say, the surface of the blade must be made into an inclined plane to convert the external force in the vertical direction into the rotational force in the horizontal direction. Because the angle between the vertical force and the horizontal force is 90°, the best angle to convert the vertical force into the horizontal force is 45°, indicating that only 1 / 2 of the vertical force can be converted into a horizontal force, that is, only half of the force does useful work,...
