Problems solved by technology

The vertical axis wind turbine has many advantages, but it has not been widely promoted. Until now, its development status is obviously behind the horizontal axis wind turbine. The reason is that it seems to be simple but has no obvious cost reduction and superior adaptability. , such as the Darrieus wind turbine, is inconvenient to be vigorously promoted due to many defects in the technology such as wind-catching ability, control method, performance-price ratio, etc.

Embodiment 1

[0022] Such as figure 1 As shown, select a common combination method of a rectangular wind cup blade wind turbine of the present invention: use a section of hollow main shaft (1) to install vertically through a ground fixing device (5), connect a flexible flange and then connect to the transducer The main shaft of the mechanism (7). A set of support arms (3) is installed on the upper end of the main shaft (1) so that it is perpendicular to the main shaft (1) and the three are at an average angle of 120° to each other. Oil pipes and control lines are connected to the controlled electro-hydraulic control device (6) and hydraulic brake device on the main shaft. Bearings, limit stops, piston hydraulic buffer parts, and movable brackets (8) are installed on the three support arms (3), and then a piece of lightweight wind cup blade (2) is connected respectively so that the axis of rotation of the bracket is aligned with the wind cup. The rectangular midline connections of the blad...

Embodiment 2

[0026] Such as figure 2 As shown, select the wind cup blade wind turbine main shaft to be installed and combined with the vertical rod or tower fixing device in a horizontal manner: install the rod or tower (10) on the rotary body, such as Figure 4 (A), the combined main shaft (1), connects the energy-transforming mechanical main shaft on the revolving body in a horizontal manner, the main shaft axis (18) and the center are eccentric to the shaft or tower axis (17). The connecting arms, brackets, and fan blades are the same as those in Embodiment 1, and will not be repeated here. When the wind comes from any direction, since the main shaft transmits the wind force to the eccentric rotator connected to the pole tower, the wind turbine will rotate to the downwind position and automatically align with the wind direction, so that the wind cup blade wind turbine combined with the main shaft in a horizontal manner can automatically face the wind . The horizontal combination meth...

Embodiment 3

[0028] Such as image 3As shown, the selection of the main shaft of the wind turbine with cup blades to be installed in a vertical manner with a vertical rod or tower fixing device is actually an extension of the ordinary combination method, but it is meaningful for large-scale reduction of costs. The main shaft (1) stands in the vertical rod or tower fixing device (10), its lower end is connected to a flexible flange and then connected to the main shaft of the energy conversion machine (7), and its upper end is connected to the tripod-shaped bracket through the rod or tower bearing (11), (12), (13), the tripod-shaped support connects the support arm (3). And the controlled electro-hydraulic control device (6) on the upper end of the main shaft (1) is connected with the high-pressure oil pipe and the control line to the hydraulic regulator (4) of the support arm rotation, and the hydraulic brake device is installed on the lower end of the main shaft. The connecting arms, brac...

Abstract

The present invention discloses one kind of wind driven engine with combined wind cups and blades, and aims at improving the operation mode of wind driven engine. The wind driven engine has one main shaft with one or several sections, and one set of arms mounted on the main shaft and with at least one wind cup-blade capable of changing upwind angle each. The wind driven engine may be driven with wind in any direction and has high efficiency, simple structure and easy control. The present invention may be used in various kinds of energy converter.

Description

technical field [0001] The invention relates to a wind turbine, in particular to a combined wind cup blade wind turbine Background technique [0002] The most widely used wind turbines in the prior art are generally horizontal-axis three-bladed wind turbines. The horizontal-axis three-blade wind turbine uses computer-aided design and control. Its technology is exquisite and close to perfection. However, the fly in the ointment is: the initial investment of the equipment is large, the maintenance cost is high, and the wind wheel is limited by the speed ratio of the blade tip. Can't make it bigger. At present, the capacity of a single unit in foreign countries has reached about 4MW. However, although the wind rotor is large, the effective utilization rate of wind energy in the whole process is not high, and the control technology is complicated. Due to cost and technical reasons, the development of domestic wind power equipment is restricted. The vertical axis wind turbine ...
