Abstract
Description
Technical Field
[0001] The utility model relates to a multi - combined wind power generation set, in particular to a small - scale wind turbine on a high - rise building. Background Art
[0002] Existing wind turbines are divided into large - scale wind turbines and small - scale wind turbines. Most large - scale wind turbines are suitable for environments with relatively large natural wind forces. The equipment cost is huge and it belongs to major projects. Most small - scale wind turbines are applied to the rooftops of high - rise buildings, and the equipment cost is relatively low. However, the input - output ratio of existing small - scale wind turbine projects is still relatively low. Due to the low equipment cost and low wind - energy conversion and power - generation efficiency, economic benefits cannot be effectively generated, and most of them still rely on financial subsidies to maintain operating costs, so they are not suitable for large - scale applications. Summary of the Invention
[0003] In order to overcome the above - mentioned deficiencies, the utility model provides a multi - combined wind power generation set with simple structure, low cost and high wind - energy conversion and power - generation efficiency.
[0004] To achieve the above purposes, the technical solution adopted by the utility model is: a multi - combined wind power generation set, including a frame, a fixed support, multiple blade - wind wheel units and multiple generators. The frame is rotatably fixed on the fixed support through a steering bearing. Both the blade - wind wheel units and the generators are fixed on the frame. The number of generators is the same as that of the blade - wind wheel units and they are arranged in one - to - one correspondence with the blade - wind wheel units. A wind guide plate is provided in front of the frame. The wind guide plate is an arc - shaped or pointed - angle structure protruding forward. The blade - wind wheel units are distributed in a "human" shape on both sides of the wind guide plate. The two - side edges of the wind guide plate cover the axes of the first - row blade - wind wheel units at the front end, and the outer edge of the previous blade - wind wheel unit on the same side covers the axis of the next blade - wind wheel unit. A wind vane is further provided at the rear end of the frame. The wind vane drives the entire frame to rotate under the action of wind force, so that the wind guide plate is always in the direction facing the wind.
[0005] The beneficial effects provided by the present utility model are as follows: Since the frame is rotatably fixed on the fixed bracket through a steering bearing, relying on the characteristic that the rudder always remains parallel to the wind direction under the action of wind, the air deflector is always in the direction facing the wind, and the wind force is deflected to the two sides and rear along the arc or sharp-angle structure of the air deflector. Eventually, the outer parts of the blade wind wheel units distributed in a "human" shape on both sides of the air deflector rotate under the action of wind force, so that the correspondingly arranged generator generates electricity. During this process, the wind force drives the blade wind wheel units on both sides of the air deflector in two opposite directions under the action of the air deflector. Since each blade wind wheel unit has no more than half of its diameter exposed to the wind force, there will be no mutual interference, and the wind force can be effectively converted into electricity. At the same time, the blade wind wheel units are distributed in a "human" shape, and the separation angle at the rear end of the "human" shape and the area bearing the wind force can be determined according to the wind force in the actual site. If the wind force at the site is large, the separation angle at the rear end of the "human" shape formed by the blade wind wheel units can be set to be smaller to reduce the area bearing the wind force. At the same time, the area bearing the wind force can also be adjusted by adjusting the height of the blade wind wheel units to avoid damage caused by excessive wind force and ensure sufficient power generation efficiency. Therefore, the multi-combination wind power generation set with this structure is simple in structure and low in cost, and can also ensure that the wind turbine is always at an efficient power generation angle, achieving a high wind power conversion and power generation efficiency. This wind power generation set with low cost and high power generation efficiency can recover the cost within a short time through the economic benefits generated by power generation, and does not require financial subsidies for promotion. It can be applied to most high-rise buildings and can be well promoted.
[0006] Further, rubber shock pads are provided around the fixed bracket. The rubber shock pads can reduce vibration and noise.
[0007] Further, fixing rings are provided at the lower ends around the frame. The fixing rings can be used to fix the lower ends around the frame with ropes in disaster weather with excessive wind force such as typhoon days to avoid damage.
[0008] Further, the blade wind wheel unit is a cylindrical vertical blade wind wheel structure, including a rotating shaft, a plurality of blades and a fixing ring. The rotating shaft is rotatably fixed on the frame. This cylindrical vertical blade wind wheel structure can conveniently adjust the blade height and the diameter of the rotating shaft according to actual needs to achieve appropriate dimensions. The fixing ring can fix the blades on the rotating shaft to rotate together with the rotating shaft.
[0009] Further, a conductive box is provided on the frame. There are two to three groups of conductive blocks in the conductive box. A conductive column is provided on the fixed bracket. There are two to three groups of conductive rings on the conductive column. The conductive blocks are correspondingly matched with the conductive rings. The multiple generators all output current through the cooperation of the conductive box and the conductive rings. The cooperation between the conductive rings on the conductive column and the conductive blocks in the conductive box enables the frame to rotate around the fixed bracket while ensuring that the generators always stably output two-phase or three-phase current, avoiding circuit interruption caused by defects such as wire winding.
[0010] Further, a groove is provided on the conductive block, and a spring is provided in the groove. The spring provides an elastic force for the conductive block in the direction of cooperation with the conductive ring. The setting of the groove and the spring in cooperation to provide the elastic force for the conductive block in the direction of cooperation with the conductive ring can keep the conductive block and the conductive ring in a state of abutting cooperation at all times.
[0011] Further, an aviation warning light is provided at the upper end of the conductive column, and the aviation warning light can play the role of aviation warning.
