Definitions
- the present invention relates to a structural technology for wind power generation, and more particularly to a structure for wind power generation that utilizes a single-blade fan while reducing the airflow generated by the operation of the leaf fans, thereby improving the overall power conversion efficiency.
- Wind power is generally a horizontal-axis wind turbine with gensets and blades at the top of the tower; it is bulky and expensive.
- Taiwan Patent Publication No. 200846551 and Announcement No. M327926 disclose a windmill that is upright and can automatically track the wind direction, and can be used as a wind power generation device with a suitable generator.
- the windmill structure of the above two patents is to form a plurality of frames on a rotating shaft, and a plurality of rotatable blades are arranged in the frame, and the blades are respectively located on opposite sides of the rotating shaft; Attempting to use the wind to rotate the frame to drive the shaft to generate electricity.
- each of the above two patents can be independently oscillated, so when the wind acts on the blade, each blade may correspond to the wind in the form of an independent oscillating motion;
- the torsion force of the hour hand is generated, and the blades on the other side of the shaft produce a counterclockwise torsion force, so that the torsion forces cancel each other and the frame cannot rotate, and the shaft cannot rotate and the generator operates.
- the main purpose of the present invention is to: through this weight block, the leaf fan can be brought to a balanced state, while When multiple leaf blades are used on the substrate, they are not affected by the airflow generated during operation, and the optimal power generation efficiency is obtained.
- the present invention is a structure for wind power generation, which comprises:
- the base body is provided with at least one mounting portion
- At least one impeller having a rotating shaft pivoted to the mounting portion, the rotating shaft combining a single leaf fan;
- the weight is mounted on the rotating shaft and corresponds to the position of the leaf fan.
- a plurality of the impellers are disposed on the same side of the base body at a time.
- a plurality of the impellers are disposed at a time and are disposed in a staggered manner on the corresponding surfaces.
- the structure of wind power generation wherein the weight of the weight is equal to the weight of the leaf fan.
- the structure of the wind power generation wherein the leaf fan is provided with an adjustment shaft for adjusting the angle of the blade.
- the beneficial effects of the invention are as follows: the weight of the leaf fan can be balanced by the weight block, and at the same time, when a plurality of leaf blades are applied to the base body, the air flow generated during operation is not affected, and the best is obtained. Power generation efficiency.
- Figure 1 is a perspective view of a preferred embodiment of the present invention
- FIG. 2 is a view showing an operation state of a preferred embodiment of the present invention.
- Figure 3 is a perspective view of another preferred embodiment of the present invention.
- FIG. 4 is a view showing an operation state of another preferred embodiment of the present invention.
- Figure 5 is a diagram showing the operational state of still another preferred embodiment of the present invention.
- the present invention is a structure for wind power generation.
- the structure 1 for wind power generation includes: a base 10, the base 10 is provided with at least a mounting portion 102; at least one impeller 12 having a pivoting portion of the mounting portion 102 a rotating shaft 120, and the rotating shaft 120 is combined with a single leaf fan 122; and a weight 14 which is mounted on the rotating shaft 120 and corresponds to the position of the leaf fan 122, and the weight of the weight 14 is equivalent to the leaf Fan 122 weight.
- FIG. 2 is a schematic diagram of the operation state of the preferred embodiment of the present invention.
- the impeller 12 faces the windward side
- the single leaf fan 122 of each impeller 12 is pushed and rotated by the wind, since only the single leaf fan 122 is used.
- the airflow generated by the impeller 12 is relatively reduced, and therefore, the remaining impellers 12 are relatively less affected by the surrounding airflow, thereby improving the overall power conversion efficiency.
- the weight of the weight 14 is equivalent to the weight of the blade 122.
- the leaf fan 122 can be brought to a balanced state.
- FIG. 3 and FIG. 4 are perspective views of another preferred embodiment of the present invention, and an operational state diagram of another preferred embodiment.
- the impeller 12 is pivoted a plurality of times and is pivotally disposed in an interlaced manner.
- the corresponding surface is not affected by the windward side of the environment. Due to the use of the double-sided impeller 12, the range of the windward surface can be enlarged, thereby improving the overall power generation efficiency.
- the impeller 12 of one of the two corresponding faces is oriented On the windward side, the single leaf fan 122 of each impeller 12 is pushed and rotated by the wind. Since only the single leaf fan 122, the air flow generated by the impeller 12 is relatively reduced, and therefore, the adjacent remaining impeller 12 receives the surrounding airflow. The effect is relatively reduced, which in turn can improve the overall power conversion efficiency.
- the weight of the weight 14 is equivalent to the weight of the leaf fan 122, thereby allowing the leaf fan 122 to reach a balanced state.
- FIG. 5 it is an operational state diagram of another preferred embodiment of the present invention.
- the double-sided, large-area leaf fan 122 is mainly used, and the leaf fan 122 is provided with a leaf fan for adjusting the leaf fan.
- the 122 angle adjustment shaft 1220 by means of the adjustment shaft 1220, allows the leaf fan 122 to change the area of the wind to achieve the efficiency of changing the structure of the wind power generation.
- the structure of the wind power generation of the present invention can achieve its efficacy and purpose when it is used. Therefore, the present invention is an invention that is excellent in practicality, and is an application for conforming to a new type of patent, and an application is made according to law. I hope that the trial committee will grant the invention as soon as possible to protect the inventor's hard work. If there is any doubt in the trial committee, please do not hesitate to give instructions, the inventor will try his best to cooperate, and feel really good.
Abstract
L'invention porte sur une structure génératrice d'énergie éolienne qui comprend une base (10) et au moins un rotor (12). Au moins une partie d'installation (12) est disposée sur la base (10). Un arbre rotatif (120) du rotor (12) est monté de façon pivotante sur la partie d'installation (102). Une turbine monopale (122) est montée sur l'arbre rotatif (120). Une masse (14) est montée sur l'arbre rotatif (120) dans une position qui correspond à la pale (122). La masse (14) équilibre la pale (122). Lorsqu'un appareil multipale (122) est monté sur la base (10), les pales ne peuvent pas être influencées par des courants d'air produits pendant le fonctionnement, ce qui permet d'obtenir le rendement de production d'énergie optimal.
