Abstract

The invention discloses a self-adaptive wind turbine. The self-adaptive wind turbine is characterized by comprising a spindle arranged vertically; a plurality of flanges are perpendicularly arranged on the spindle; the two ends of each flange are connected with connecting rods respectively; each connecting rod is sleeved with a sleeve; the sleeves are connected with the corresponding connecting rods in a sliding mode; the sleeves are movably connected with blades; the connecting rods, the sleeves and the blades on the two sides of each flange are symmetrically arranged on the two sides of the spindle; each blade is an arc-shaped blade section with uneven densities; the lengths of the sleeves are distributed gradually increase and then gradually decrease from top to bottom. The blades on the two sides of the spindle are distributed like a curve-form structure of blades of a Darrieus type wind turbine. The self-adaptive wind turbine is easy to machine, small in overall size and low in manufacturing cost, has the performance and characteristics of the Darrieus type wind turbine and has important significance for future development and application of vertical axis wind turbines.

Description

A kind of self-adapting type wind energy conversion system
Technical field
The invention belongs to technical field of wind power generation, be specifically related to a kind of self-adapting type wind energy conversion system.
Background technique
Typical lift-type wind energy conversion system mainly contains the Darrieus and linear wing vertical axis windmill, comparatively speaking, linear wing blade of vertical axis wind turbine structure is simple, easy processing, machine volume is little, and processing cost is low, transport is installed relatively easy, but when this structure blade rotates, centrifugal force makes blade produce very large flexural stress at middle section position, easily causes the damage of blade, and its aerodynamic characteristic and wind energy utilization have certain deficiency relative to the Darrieus.And the Darrieus adopts curvilinerar figure curved vane, curved vane only bear tension force, do not bear centrifugal force load, flexural stress is minimum, can run with higher speed, has good aerodynamic characteristic and higher wind energy utilization, but the curved blade structure special due to it and top-type complete machine structure, its cost of production is increased greatly, and manufacturing process is relative complex also, and its huge volume is not easy to transport and installs.
Summary of the invention
The object of this invention is to provide a kind of self-adapting type wind energy conversion system, solve the blade existed in prior art and easily damage or do not bear the problem of centrifugal force load.
The technical solution adopted in the present invention is, a kind of self-adapting type wind energy conversion system, comprises the main shaft vertically arranged, main shaft is vertically installed with several flange plate, the two ends of each flange plate are connected to connecting rod, and connecting rod is arranged with sleeve, sleeve is connected with rod slide, and sleeve is connected with blade; Connecting rod in each flange plate both sides, sleeve and blade symmetry is all arranged at the both sides of main shaft; Blade is Density inhomogeneity arc-shaped leaf fragment; The length of sleeve from top to bottom in from short to long, then distributes from long to short; The blade distribution in the Darrieus blade curved configuration respectively of main shaft both sides.
Feature of the present invention is also:
Along main shaft from top to bottom to the longest sleeve place, blade is that upper end density is large, the arc-shaped leaf fragment that lower end density is little; Downward from the longest sleeve place along main shaft, blade is that lower end density is large, the arc-shaped leaf fragment that upper end density is little.
The two ends of flange plate are all fixedly connected with connecting rod by the first screw and the first nut.
Blade is provided with fixed plate, and sleeve is flexibly connected with fixed plate by the second screw and the second nut.
The invention has the beneficial effects as follows: blade adopts the synthesis of Density inhomogeneity prismatic blade section, the beam connecting blade sections adopts extension type to be free to slide connecting rod and sleeve, wind energy conversion system is in rotary course, blade self adaption forms the Darrieus blade curved configuration, this wind energy conversion system easy processing, machine volume is little, and processing cost is low, there is again the performance characteristics of the Darrieus simultaneously, the development in vertical axis windmill future and application are had very important significance.

In figure, 1. blade, 2. screw, 3. flange plate, 4. connecting rod, 5. nut, 6. screw, 7. nut, 8. main shaft, 9. fixed plate, 10. sleeve.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
The invention provides a kind of self-adapting type wind energy conversion system, as shown in Figure 1, comprise the main shaft 8 vertically arranged, main shaft 8 is vertically installed with several flange plate 3, the two ends of each flange plate 3 are connected to connecting rod 4, connecting rod 4 is arranged with sleeve 10, sleeve 10 and connecting rod 4 are slidably connected, and sleeve 10 is connected with blade 1; Connecting rod 4 in each flange plate 3 both sides, sleeve 10 and blade 1 are symmetricly set in the both sides of main shaft 8; Blade 1 is Density inhomogeneity arc-shaped leaf fragment; The length of sleeve 10 from top to bottom in from short to long, then distributes from long to short; Blade 1 distribution in the Darrieus blade curved configuration respectively of main shaft 8 both sides.
Along main shaft 8 from top to bottom to the longest sleeve 10 place, blade 1 is that upper end density is large, the arc-shaped leaf fragment that lower end density is little; Downward from the longest sleeve 10 place along main shaft 8, blade 1 is that lower end density is large, the arc-shaped leaf fragment that upper end density is little.
The two ends of flange plate 3 are all fixedly connected with connecting rod 4 by the first screw 2 and the first nut 5.Blade 1 is provided with fixed plate 9, sleeve 10 is flexibly connected with fixed plate 9 by the second screw 6 and the second nut 7.
The using method of this device is: be inserted on ground by this device along main shaft 8, and wind energy conversion system is in rotary course, and along main shaft 8 from top to bottom to the longest sleeve 10 place, blade 1 is that upper end density is large, the arc-shaped leaf fragment that lower end density is little; Downward from the longest sleeve 10 place along main shaft 8, blade 1 is that lower end density is large, the arc-shaped leaf fragment that upper end density is little, the blade 1 in main shaft 8 side can form the Darrieus blade curved configuration automatically, in the opposite side blade 1 meeting forming curves shape structure equally of main shaft 8; Meanwhile, sleeve 10 and connecting rod 4 are slidably connected, and this device along with the size of wind-force, can change the total length of sleeve 10 and connecting rod 4, and then change curved size.Like this, wind energy conversion system is in rotary course, blade sections self adaption forms the Darrieus blade curved configuration, this wind energy conversion system easy processing, machine volume is little, processing cost is low, has again the performance characteristics of the Darrieus simultaneously, has very important significance to the development in vertical axis windmill future and application.
