Abstract
The utility model discloses a kind of vertical-axis windmill, including a machine seat, a main axis vertically arranged on the machine seat and the leaf. A plurality of leaf support plates arranged in the horizontal direction are on the upper and lower parts of the main axis; the upper and lower leaf support plates are faced to each other; on the leaf support plates is arranged the positioning finial bolt; the support connecting rod is arranged on the end part of the leaf support plates; the leaf is connected with the positioning finial bolt in the rotary way through the finial holes arranged on the upper and lower parts of the leaf. The utility model is of reasonable design, low starting wind speed, flexible, rotation, and high rotary speed, convenient replacement of the leaf, high output power, and high work efficiency.
Description
Technical field
The utility model relates to a kind of wind power plant, particularly a kind of vertical axis windmill.
Background technique
At present, a kind of vertical shaft movable fan blades windmill appears in the wind-power electricity generation industry, is ZL200420086261.1 as the patent No., and name is called " the gyro type air transformation application of force continues to quicken to be subjected to the force unbalance windmill " disclosed patented technology.Owing to reasons such as structural design and manufacturing process, deficiency such as in use there is bad adaptability in most products, require starts the wind speed height, rotating speed is low, blade rotation is dumb, replacing is difficult, inefficiency, output power are little.
The model utility content
The purpose of this utility model is the deficiency that exists at prior art, a kind of reasonable in design is provided, rotates flexibly, blade exchanging convenience, high working efficiency, vertical axis windmill that the startup wind speed is little.
The technical solution of the utility model is: a kind of vertical axis windmill, comprise support 2, be vertically set on main shaft 1 and blade 3 on the support 2, it is characterized in that: at the two ends up and down of main shaft 1, a plurality of fan blade dunnages 6 have been horizontally disposed with, fan blade dunnage 6 is relative in twos up and down, fan blade dunnage 6 is provided with the top bolt 7 in location, and the end of fan blade dunnage 6 is provided with supporting linkage 5; The center hole that described blade 3 is provided with by its upper and lower end is rotationally connected with the top bolt 7 in location.
The utility model compared with prior art has the following advantages: the utility model is reasonable in design, high working efficiency, rotation flexibly, start that wind speed is little, rotating speed is high, blade exchanging is convenient, can effectively utilize the wind comes from of all directions, output power is big.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 locatees the structural representation of top bolt 7 for the utility model.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises support 2, is vertically set on main shaft 1 and blade 3 on the support 2; At the two ends up and down of main shaft 1, be horizontally disposed with three arc fan blade dunnages 6 respectively, the angle that adjacent fan blade dunnage is 6 is 120 degree, fan blade dunnage 6 is relative in twos up and down, and in its end supporting linkage 5 is set; The top bolt 7 in location is set on fan blade dunnage 6, and the top bolt 7 in location on the fan blade dunnage 6 is rotationally connected blade 3 by the center hole on the two ends down disposed thereon and about being arranged on.
During the utility model work,, on fan blade dunnage 6, be provided with position limit pin 4 corresponding to each sheet blade 3 for adjusting and limit the pivotal position of blade 3.
As shown in Figure 2, be used to the to be rotationally connected top bolt 7 in location of blade 3 is conical bolt for the termination.
