Abstract
The utility model discloses a horizontal axis wind-driven generator for enhancing blade strength. The horizontal axis wind-driven generator comprises a generator unit and blades, wherein the blades are arranged on a main shaft of the generator unit; and an upright post is arranged at the top of the main shaft, reinforcing ribs which are connected with the blades are arranged at the top of the upright post, and the adjacent blades are connected by the reinforcing ribs. Compared with the prior art, the horizontal axis wind-driven generator has the advantages of improving the blade strength, increasing the blade length and stress area so as to improve single-machine power, avoiding vibration of single blade due to self weight and air turbulence so as to produce more stable power output, avoiding blade vibration, reducing the fatigue degree of the blades and prolonging the service life of the blades; and under the condition that the same blade material is used, the wind-driven generator with higher single-machine power can be manufactured.
Description
The application requires number of patent application to be: 200920263035.9, and patent name is: increase the axial column backguy of horizontal axis wind-driven generator blade strength technology, the applying date is: the China on November 20th, 2009 is in the preference of first to file.
Technical field
The utility model relates to technical field of wind power generator, especially relates to a kind of horizontal axis wind-driven generator that strengthens blade strength.
Background technique
Existing wind-driven generator needs to improve intensity, length, the lifting surface area of wind wheel blade in order to improve single-machine capacity, and is stressed to strengthen, and improves the efficient of power output.Yet the blade of existing wind-driven generator just is connected and fixed in bottom and main shaft, and the raising of the intensity of blade, length, lifting surface area is subjected to the restriction of blade material physical property; Like this, under the situation of same material, just limit the raising of wind-driven generator single-machine capacity, reduced the utilization of wind energy.Therefore be necessary to be improved.
The model utility content
Deficiency at above-mentioned prior art existence, the purpose of this utility model provides a kind of intensity, length, lifting surface area that can improve wind wheel blade under the identical blade material situation greatly that use, and can produce the horizontal axis wind-driven generator of the bigger enhancing blade strength of single-machine capacity.
To achieve these goals, the technological scheme that the utility model adopted is: strengthen the horizontal axis wind-driven generator of blade strength, comprise generator set and blade, blade installation is on the main shaft of generator set; Be provided with a column on the top of main shaft, the top of column is provided with stiffening rib and is connected with each blade respectively, is provided with stiffening rib between the adjacent blades and connects.
The central lines of described column and main shaft, when the work operation, column and main shaft keep rotating synchronously.
Described blade is provided with the stay thimble of being convenient to install stiffening rib, and all stiffening ribs are connected with stay thimble.
Vertically be embedded with principal rod in the described blade, the central lines of principal rod and blade, stay thimble is installed on the principal rod.
Described blade caves inward on the surface that the stay thimble place is set, and exposes stay thimble, so that does not influence in the fan operation process adjustment to blade angle;
Described stiffening rib is the high-tensile steel wires backguy.
After adopting said structure, the utility model is compared the advantage that is had with prior art and is: adopt axial column and stiffening rib ways of connecting are set, blade and blade, blade and column are connected into an integral body; Making the plane that forms between blade, column and stiffening rib is that stable triangle, each solid space is stable tetrahedron, and the blade strength of the axis wind power generator of can improving the standard increases length of blade and lifting surface area, thereby improves single-machine capacity; Can avoid individual blade because the vibration that weight of self and air turbulence cause makes power output more stable; Can avoid blade vibration, reduce the blade degree of fatigue, can prolong blade service life; Use under the same blade material situation, can produce the bigger wind-driven generator of single-machine capacity.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the perspective view of the horizontal axis wind-driven generator of enhancing blade strength of the present utility model.
Fig. 2 is the partial structurtes schematic representation of the horizontal axis wind-driven generator blade of enhancing blade strength of the present utility model.
Embodiment
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
Strengthen the horizontal axis wind-driven generator of blade strength, as shown in Figure 1, comprise generator set 1 and blade 2, blade 2 is installed on the main shaft of generator set 1, and generator set 1 is fixed on the pole 4; Be provided with a column 3 on the top of main shaft, the top of column 3 is provided with stiffening rib 5 and is connected with each blade 2 respectively, is provided with stiffening rib 5 between the adjacent blades 2 and connects.Blade and blade, blade and column are connected into an integral body; Making the plane that forms between blade, column and stiffening rib is that stable triangle, each solid space is stable tetrahedron, can the improve the standard blade strength of axis wind power generator, thereby can under the situation of identical manufactured materials, increase the length and the lifting surface area of blade, improve single-machine capacity.The central lines of column 3 and main shaft, when the work operation, column 3 can keep synchronous rotation with main shaft.Blade 2 is provided with the stay thimble 7 of being convenient to install stiffening rib 5, and all stiffening ribs 5 are connected with stay thimble 7.In blade 2, vertically be embedded with principal rod 6, the central lines of principal rod 6 and blade 2, stay thimble 7 is installed on the principal rod 6.The surface that blade 2 is provided with stay thimble 7 places caves inward, and exposes stay thimble 7, so that does not influence in the fan operation process adjustment to blade angle; Stiffening rib 5 can be the high-tensile steel wires backguy.Blade 2 can be provided with more than three or three on the main shaft.
The foregoing description is not to be to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification; therefore all technological schemes that are equal to also should belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
