Abstract

The utility model relates to a novel wind generator. The utility model is composed of wind blades, a wheel shell, a transmission system, an accelerating gearbox and a tower frame, one surface of one wind blade is a plane, and the back surface is arc-shaped; the wheel shell which is composed of a frame on which the wind blades are arranged is cylindrical; the wind blades are arranged on the wheel shell which is arranged on the tower frame, and the wheel shell and the accelerating gearbox are connected by the transmission system. When the wind acts on the utility model, most of the wind acts directly the planar surfaces of the wind blades to generate direct driving force, meanwhile, the wind permeates the frame of the wheel shell and acts on the wind blades which are in back stroke state, and the back surfaces of the wind blades are arc-shaped, which makes the back wind of the wind blades enlarged to generate side force and thus enhance furthest the acting effect of the wind.

Description

Novel wind generator

The utility model relates to a kind of novel wind generator.

Wind-power electricity generation be a kind of pollution-free, can regenerate and use the energy repeatedly, the wind-driven generator that is used for wind-power electricity generation at present, following several types is roughly arranged: the one, horizontal shaft type, adopt propeller formula blade, not enough place is that generator will be placed on the axle that paddle drives, wind-force is done time spent blade back and is produced eddy current, forms certain resistance; The 2nd, Da Lushi (perpendicular axis type) adopts arc paddle to be contained on the vertical shaft, be characterized in wind-engaging not to influence and can partly integrally be placed on ground than the heavy-duty machine tool with what wind-force is transferred to electric power, not enough place is to start voluntarily, must borrow external force; The 3rd, interior wind sail type is contained in sail shape blade on the vertical shaft, not enough place be blade when entering the backhaul district and moving against the wind resistance bigger; Also has a kind of perpendicular axis type that also adopts, fan blade is assembled by leaf frame and some movable small leaf, backhaul is that small leaf opens and reduces resistance, but when wind direction and blade greater than or when being less than 90 °, the blade incompetence occurs and air leakage phenomena occurs, having influenced active area, secondly is complex structure, and maintenance difficult is time-consuming.

The purpose of this utility model is exactly in order to overcome the deficiency of above-mentioned technology, and a kind of novel wind generator is provided.

Novel wind generator is made up of leaf blade, hub, transmission system, step-up gear, pylon, it is characterized in that the one side of leaf blade is the plane, and the back side is the garden arc; Hub is made up of the framework that leaf blade is installed, and is the garden cylindricality; Leaf blade is installed on the hub, and hub is installed on the pylon, and transmission system links together hub and step-up gear.

Because leaf blade is the garden arc, hub is made up of framework, and when wind-force acted on this wind-driven generator, most of wind-force directly acted on the fan blade blade face of plane shape, produces direct driving force; Wind-force sees through the hub framework and acts on the leaf blade that is in the backhaul state simultaneously, because the back side of leaf blade is the garden arc, the back side wind-force of leaf blade is increased, and has produced a kind of lateral force, thereby has improved the stress efficacy of wind-force to greatest extent.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the utility model leaf blade active force is analyzed schematic representation.

Describe in detail below in conjunction with accompanying drawing.

As shown in the figure, the 1st, leaf blade, the 2nd, hub, the 3rd, transmission system, the 4th, step-up gear, the 5th, pylon, the 6th, framework.

Novel wind generator is made up of leaf blade, hub, transmission system, step-up gear, pylon, and the one side of leaf blade is the plane, and the back side is the garden arc; Hub is made up of the framework that leaf blade is installed, and is the garden cylindricality; Leaf blade is installed on the hub, and hub is installed on the pylon, and transmission system links together hub and step-up gear.

When wind-force acted on leaf blade, the front of leaf blade was the plane, the air pressure height; The back side of leaf blade is the garden arc, and the back side wind-force of leaf blade is increased, and air pressure is low, thereby produces lateral force, and the resistance when being about to backhaul becomes lateral force, has improved pneumatic efficient.

Wind-force drives leaf blade and rotates, and hub is with the fan blade blade rotation, and hub rotates by the axle core that transmission system drives in the step-up gear, this kinetic energy is outputed to coil, thereby realized that wind energy is converted to electric energy.
