Description

Multi-bladed wind power plant

technical field

The utility model relates to a wind power generation device, in particular to a multi-blade wind power generation device.

Background technique

At present, most of the equipment used for power generation is powered by water power or fire power. These power generation equipment construction projects are large, the equipment is huge, and the cost is high. It is only suitable for the development and utilization of large institutions and units. It is not conducive to the development and utilization of power in resource-poor and economically backward areas and rural areas, and is not conducive to improving and promoting the development of the local economy. , must find another way and method.

Contents of the invention

The purpose of the utility model is to provide a multi-blade wind power generation device which can utilize wind resources and combine small blades into large blades as the impeller to generate power to drive the engine to generate electricity.

The utility model comprises small blades, large blades, leaf racks, snaps, brackets and a central shaft, wherein the small blades are respectively connected to the leaf racks with snaps to form large blades, and at least four large blades can form wind turbines. The leaves are attached to the bracket.

The small blades are inclined to the center of the bottom according to the required angle.

The central shaft is connected and sleeved in the bracket, and is connected to the generator through the bearing and the gear set installed in the bearing seat.

The utility model adopts bearing seats and bearings to reduce friction, rotate the shaft flexibly, increase the speed, and reduce energy consumption; the wind wheel is composed of large and small blades, and the small blades are connected by loose buckles, which can adapt to the blowing changes of different wind directions and wind speeds , which is conducive to opening and closing, and improves the utilization rate of the fan blades.

Description of drawings

Accompanying drawing is a schematic plan view of the structure of the utility model.

Detailed ways

Illustrate in conjunction with accompanying drawing and embodiment.

As shown in the figure, first build up the machine room 9 on the ground of the wind field, install the bracket 6, then install the bearing housing 8 and its bearing 7, then install the gear set 10 in the machine room 9 to connect it with the generator 11, and then install the The central shaft 2 is sleeved in the bracket 6 . When the wind moves, the large blade 1 composed of the small blade 5 connected to the leaf frame 3 by the loose buckle 4 is blown by the wind and rotates, driving the central shaft 2 connected to the bracket 6 to rotate, and the transmission is transmitted through the bearing 7 To the gear set 10 to make it change speed and drive the generator to generate electricity. In order to make the small blades 5 automatically close, each small blade is inclined to the center below by a required angle, that is, it is inclined to the central axis direction. When the wind blows to the closed side, it will block the wind to generate power, and the blades will rotate. When the wind blows to the other side, the small blades will be opened and ventilated due to the action of the buckle 4, and the blades will not rotate, so the large blade 1 will always move forward. Rotate in one direction to drive the central shaft to rotate and make the gear rotate and drive to work.

Claims (3)

1, a kind of leafy wind generating unit, comprise small leaf, big blade, leaf frame, knot that can be undone by a pull, support and central shaft, it is characterized in that, small leaf wherein (5) is connected on the leaf frame (3) with knot that can be undone by a pull (4) separately and is connected into big blade (1), and this big blade (1) can be connected on the support (6) by 4 composition fan blades at least.
