Vertical axis wind turbine

Abstract

The invention discloses a vertical axis wind turbine. The vertical axis wind turbine comprises a windshield wall, a windshield rail, a fan blade frame, fan blades, a first check block, a second check block, a vertical shaft, a fan blade shaft and the like. According to the vertical axis wind turbine, the fan blades are matched on the fan blade shaft and are matched with some limits, in this way, the direction of the fan blades is changed in a reciprocating mode, so that the maximum power air and the minimum resistance air are obtained, under the combined action of the plurality of sets of fan blades, through the transmission of a horizontal transmission shaft, the kinetic energy of the wind energy obtained by each set of fan blades is concentrated to a gearbox, then a proper rotating speed and torque are transmitted to a corresponding generator set after speed change of the gearbox, so as to achieve the best power generation effect so as to ensure that the optimal electricity quantity is emitted. The vertical axis wind turbine has the beneficial effects that the wind energy conversion rate is increased, the power generation efficiency is ensured, the energy is saved, and a large amount of carbon emission is reduced.

Description

technical field [0001] The invention relates to a power facility, in particular to a vertical axis wind power generator. Background technique [0002] With the increasing trend of global warming, many countries have invested a lot of manpower and material resources in an effort to improve our common living environment; the existing wind power technology has become increasingly mature, creating a large amount of clean electricity for the world, to a certain extent It has alleviated the excessive emission of carbon dioxide and saved a lot of energy; however, most of the existing wind power technologies still have some problems, such as: the existing technology has high production costs, slow returns, high maintenance costs, and unsatisfactory power generation. No power generation, strong winds cannot generate electricity, because the wind speed is too fast, once the wind generates power, the whole machine will often be blown down, and the service life of the existing technolog...

Problems solved by technology

[0004] A vertical axis wind power generator includes a windshield wall, a windshield rail, a blade frame, blades, a first block, a second block, a vertical shaft, a blade shaft, a support frame, a blade block, a small unit, a horizontal Drive shaft, gearbox, large-scale unit, medium-sized unit; the fan blade is matched on the fan shaft, and the fan blade can rotate freely around the fan shaft, so the fan blade frame is provided with a fan blade block to limit the fan blade The rotation angle of the fan blade is further divided into the first block and the second block; when the wind direction is shown in the figure (Fig. (3)), the fan blade frame will Under the effect of wind force, the vertical axis is driven to rotate, and when the fan blade frame is in the position of D, E, F, it will be automatically adjusted to the position as shown in the figure (Figure (3)) due to the installation of the windshield wall. This area is not affected by the wind force. To ensure that the vertical axis can obtain a sufficient torque, however, when rotating, the fan blade frame and the fan blade group will be subjected to rotational resistance in the direction of rotation. The reverse of the blade frame rotation is naturally opened to the second stop, which can greatly reduce the wind resistance of the blade when it is passively rotated, thereby increasing the torque of the vertical axis again; when the blade frame is turned from F position to A position , the three open fan blades will rotate towards the fan blade frame under the action of wind force until they are blocked by the first stopper, so as to ensure that this group of fan blades can always obtain the best wind force when they turn to the C position; However, at the same time, the vane frame will turn from position C to position D, and three of the vanes will lose the effect of power wind, and will rotate in the direction of the second block under the action of resistance wind. After opening, The resistance of the resistance wind to the blade group will reach the minimum; the movement state of the other groups of blades changes the direction of the blades in this way to obtain the maximum power wind and the minimum resistance wind, so as to ensure that the vertical axis has sufficient power , and then through the horizontal transmission shaft, the power of the vertical axis of each unit branch is combined, and after the speed is changed through the gearbox, the wind turbine corresponding to the wind is selected to ensure the best power generation; due to the great uncertainty of the natural wind In response to this situation, the present invention designs three generator sets of different sizes, namely, a large unit, a medium unit, and a small unit, in order to cope with different wind forces and adjust the best generator set work to achieve the best wind power. In the best power generation state, since there is a firm support frame, the support frame will be designed with different strengths according to the size of the designed wind power station. In order to ensure the demand for earthquake resistance and super wind resistance, reinforced concrete or steel frame structures can be used; Under the joint action of the groups of fan blades, the wind energy kinetic energy obtained by each group of fan blades is transferred through the horizontal transmission shaft to the gearbox, and then the appropriate speed and torque are transmitted to the corresponding generator set after the gearbox is shifted. In order to achieve the best power generation effect; the windshield track is set on the bottom and top of each layer to achieve the function of stabilizing the windshield wall. Under the action of the driving motor, it can rotate freely, but it is limited by the wind direction, and always maintains the windward position to reduce the resistance of the wind blade group at the leeward. The height of the windshield wall is related to the support The height of the bracing frame is similar
