Abstract
The utility model relates to a cantilever device for rectilinear negative pressure wind energy conversion system, limit, intermediate junction limit, right side connection limit and intermediate strut limit are connected including the left side, the left side connect the limit with the right side is connected the limit and is passed through intermediate junction limit bilateral symmetry, the intermediate strut limit is passed through the intermediate junction limit is connected the left side connect the limit with the limit is connected on the right side, and every quartette becomes the four sides diamond structure, the intermediate junction limit of cantilever is equipped with 3 at least four sides diamond structures. The utility model discloses a cantilever device length of rectilinear negative pressure wind energy conversion system is inequality, has realized on the same connecting axle that circular motion is together to different radial wind wheels more than 3, improves the utilization ratio of wind energy greatly.
Description
Technical field
This utility model is particularly used for the cantilever arrangement of rectilinear negative-pressure air power machine.
Background technology
It is relatively low that the problem that the widely used wind energy conversion system of wind-power electricity generation exists at present is mainly wind energy utilization, can only achieve the wind energy utilization of about 17%, owing to being restricted by blade material and technology, it is difficult to manufacture high-power wind mill, limit the output of separate unit wind energy conversion system.Prior art also devises some technical schemes solving the low problem of above-mentioned wind energy utilization, such as being declared by Beijing Jiaotong University of the Decree of Patent Office of China in 2008, Authorization Notice No. is CN201031769Y, the technical scheme that the patent of invention of the patent of invention entitled " a kind of vertical shaft wind motor windwheel device " that China Patent No. (ZL) is 200720149499.8 is used.Its semicolumn wind-force regulating gate can box haul and change its position with regulate fan blade wind area, when it rotate in place on the direction windward of rotary shaft side, when having blocked whole blade wind surface half, the utilization of wind energy also arrives at summit.But the highest wind energy 100% that also can only achieve 50%(side of wind-force utilization rate deducts the windage 50% of opposite side equal to 50% in such scheme), its utilization rate still ratio is relatively low.The most how to improve wind energy utilization, become the major subjects of current vertical wind machine technology research and development.
Summary of the invention
In order to solve technical problem present in background above technology, this utility model provides the cantilever arrangement for rectilinear negative-pressure air power machine, rational in infrastructure, technique is simple, cost is low, it is possible to be effectively improved wind energy utilization.
For the above-mentioned technical problem solved, this utility model takes techniques below scheme:
Cantilever arrangement for rectilinear negative-pressure air power machine, it is characterized in that: described cantilever arrangement (1) includes that left side connects limit (11), middle connects limit (12), connection limit, right side (13) and intermediate supports limit (14), it is symmetrical by described middle connection limit (12) that connection limit, described left side (11) is connected limit (13) with described right side, described intermediate supports limit (14) connects connection limit, described left side (11) by described middle connection limit (12) and is connected limit (13), every four composition four limit diamond structures with described right side；Connect limit (12) in the middle of described cantilever arrangement (1) and be provided with at least 3 four limit diamond structures.
Described cantilever arrangement (1) is made up of aluminium sheet or stainless steel material.
This utility model provides for the cantilever arrangement of rectilinear negative-pressure air power machine, rational in infrastructure, technique is simple, cost is low, it is possible to be effectively improved wind energy utilization.The beneficial effects of the utility model are:
1, this utility model is differed by cantilever arrangement (1) length of rectilinear negative-pressure air power machine, it is achieved that in same connecting shaft, the wind wheel of more than 3 different radiis moves in a circle together, is greatly improved the utilization rate of wind energy.
(4) accompanying drawing explanation:
By the description below in conjunction with the accompanying drawings exemplary embodiment carried out, above-mentioned purpose of the present utility model and feature will be made apparent from and it can be readily appreciated that wherein: Fig. 1 shows the cantilever arrangement top view structural representation for rectilinear negative-pressure air power machine into this utility model embodiment；
Reference is: cantilever arrangement 1, connection limit, left side 11, middle connection limit 12, connection limit, right side 13, intermediate supports limit 14.
(5) detailed description of the invention:
(embodiment 1)
Fig. 1 shows the cantilever arrangement top view structural representation for rectilinear negative-pressure air power machine into this utility model embodiment.
The present embodiment is the cantilever arrangement for rectilinear negative-pressure air power machine, as shown in Figure 1, described cantilever arrangement (1) includes that left side connects limit (11), middle connects limit (12), connection limit, right side (13) and intermediate supports limit (14), it is symmetrical by described middle connection limit (12) that connection limit, described left side (11) is connected limit (13) with described right side, described intermediate supports limit (14) connects connection limit, described left side (11) by described middle connection limit (12) and is connected limit (13), every four composition four limit diamond structures with described right side；Connect limit (12) in the middle of described cantilever arrangement (1) and be provided with at least 3 four limit diamond structures.
In the present embodiment, described cantilever arrangement (1) is made up of aluminium sheet or stainless steel material.
In the present embodiment, the operation principle of described rectilinear Negative pressure wind wheel wind energy conversion system: by the rectilinear Negative pressure wind wheel of rectilinear Negative pressure wind wheel wind energy conversion system, utilize negative pressure turbulent flow push type principle, differed by the cantilever arrangement length on rectilinear Negative pressure wind wheel, more than 3 symmetrical bladings are arranged in same connecting shaft, it is achieved that in same connecting shaft, the wind wheel of more than 3 different radiis moves in a circle together；And then drive electrical power generators.
Obviously, above-described embodiment of the present utility model is only for clearly demonstrating this utility model example, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also cannot all of embodiment be given exhaustive.And these belong to obvious change that connotation of the present utility model extended out or variation still falls within protection domain of the present utility model.
