Compared with the prior art, the fan cover device is simple in structure, convenient to manufacture, assemble and maintain and flexible in rotation. When half of the fan vane wheels are in action, wind accepting resistance of the other half of the fan vane wheels is small, so that the fan cover device can reduce resistance and consumption and is high in efficiency and the like.
Description
Technical field
The utility model relates to a kind of power plant of wind-drive, especially a kind of vertical shaft fan fan housing device.
Background technique
Wind-power electricity generation is called as clean energy resource and can plays good environmental-protection function, but foundation along with more and more large-scale wind electricity factories, some are begun to highlight by the problem that the horizontal axis blower fan is caused, the blade cuts air-flow that causes rotating under high speed as the defective that designs produces very big aerodynamic noise, and a lot of birds also are difficult to escape by luck under such high speed blade.Particularly its generator is installed in the top, and to the requirement height of pillar, it is all convenient inadequately to install and keep in repair.Along with improving constantly of development of science and technology and human knowledge's level, vertical shaft fan obtains the attention of more and more mechanisms and obtained significant progress in positive R﹠D process with its outstanding advantage on energy-conserving and environment-protective and cost performance.Ripe vertical shaft fan is based on its advanced design method, remedied the major defect of horizontal axis blower fan, have noise free, pillar light, install and keep in repair advantages such as easy, broken through the poor efficiency pattern of traditional horizontal axis blower fan system " wind hour commentaries on classics; stop when wind is big ", avoid electric current off and on to the impact of electrical network simultaneously, possessed wide market application prospect more.But because the fan blade of vertical shaft fan is that the center rotates at horizontal plane with the vertical shaft, when one side blade during in acting, the another side blade will run into windage, offset the part wind energy, greatly reduce making full use of of wind energy.Though Chinese patent ZL200420040915.7 and ZL200920071612.4 overcome above-mentioned not enough aspect some trial, but still there are some problems, the blower fan fan housing opening of Chinese patent ZL200920071612.4 is little, work under draught fan impeller can only promote in the wind energy of 1/4th fan housing openings; Chinese patent ZL200420040915.7 blower fan fan housing is streamline in the direction of the wind comes from, but wind direction do not fix, when side direction had wind, the blower fan fan housing was the windage of aggrandizement apparatus, made pedestal bear big external force.More than these subject matters that improve to exist be that its structure is still comparatively complicated, processing, install and maintenance still convenient inadequately, rotate also underaction with the wind.In addition, they have all increased the windage of equipment, and when wind-force acquired a certain degree, equipment damaged easily.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existing vertical axis windmill, a kind of simple structure is provided, processing, installation and maintenance are all convenient, and rotate flexibly, when one side fan blade does work, the another side fan blade is subjected to wind resistance less, and then falls the efficient vertical axis blower fan fan housing device of resistance, consumption reduction.
The purpose of this utility model can realize by implementing following technological scheme:
Being provided with one on the main shaft of conventional vertical shaft fan, to be covered in draught fan impeller peripheral and account for 1/4th to 1/2nd circular arc fan housing by circumferential surface that some draught fan impellers constitute, the upper panel of this circular arc fan housing and lower panel flexibly connect with described main shaft corresponding part respectively, are fixedly connected with a wind-guiding empennage on the top of circular arc fan housing.The utility model can also be further by adopting following measures to obtain better technique effect: the circular arc part of the circular arc fan housing of above-mentioned cover part draught fan impeller is designed to streamline, so that wind-force passes through from its outer surface swimmingly; The circular arc part of described circular arc fan housing is designed to be formed by some louvre blade stack combinations, is beneficial to reduce its whole windage; Be respectively equipped with radial ball bearing and following radial ball bearing in the upper panel of above-mentioned circular arc fan housing and the active connection place of lower panel and described main shaft; Below the following radial ball bearing that is provided with in the active connection place of the lower panel of above-mentioned circular arc fan housing and described main shaft a plane bearing can also be set.
The utility model has simple structure compared with prior art, processing, install and maintenance all convenient, and rotate flexibly, when one side fan blade did work, the another side fan blade was subjected to wind resistance less, and then had the resistance of falling, consumption reduction and characteristics such as efficient.

Embodiment
On the main shaft 1 of conventional vertical shaft fan, be connected with the streamline fan housing 3 that a circular arc is made of some wind guiding louver sheet 2 combination stacks, this fan housing 3 is covered in the periphery of draught fan impeller 4, and account for by draught fan impeller 4 constitute 1/2nd of circumferential surface, the top of fan housing 3 is fixedly connected with a wind-guiding empennage 5.Upper panel active connection place at above-mentioned vertical shaft fan main shaft 1 and streamline fan housing 3 is provided with radial ball bearing 8, is provided with down radial ball bearing 7 and plane bearing 6 respectively from top to down with the lower panel active connection place of streamlined fan housing 3.When wind when a certain direction blows, because the leading role of wind-guiding empennage 5 makes the fan housing of being made up of wind guiding louver sheet 23 turn to over against the direction of the wind comes from.At this moment, the not one side draught fan impeller 4 that is blocked by fan housing 3 generating of under the wind-force effect, doing work, another side draught fan impeller 4 is owing to blocked by fan housing 3, thereby can not produce windage and do negative work, thereby improves wind energy utilization, reaches and reduces windage and energy consumption purpose.Simultaneously because the uncertainty of the direction of the wind comes from, when the fan housing 3 that wind guiding louver sheet 2 is housed when coming wind direction, the wind that side direction is blown can pass through from the gap location of wind guiding louver sheet 2, makes the windage minimum that fan housing 3 bears, reduce cost of equipment maintenance, prolong the working life of equipment.The upper panel of vertical shaft fan main shaft 1 and streamline fan housing 3 and the plane bearing 6 that the lower panel active connection place is provided with respectively, following radial ball bearing 7 and last radial ball bearing 8, it is more flexible to make that fan housing 3 rotates on vertical shaft fan main shaft 1, has also further reduced the energy loss that is caused by friction.
