Abstract

The utility model discloses an omnidirectional collecting and enlarging wind tower type frame for erecting vertical shaft fans in a wind power generation system. The tower type frame is composed of a streamline wing-shaped upright column, an integral partition board whose middle part is a tabular cube and the outside is axe-shaped streamline form, and a wind shield plate additionally arranged on the circumference of a fan room. With the utility model, the wind resistance phenomenon is effectively improved, the wind speed of the fan room can be stably increased, a fan can acquire the wind speed twice of the nature wind, and the wind speed is increased in multiples with the increased height. The wind energy availability ratio is visibly improved, and power generation ability is obviously improved. The utility model has the advantages of simple structure, reasonable design, easy production, favorable use, saved material, saved land occupation, reduced investment, large energy output, high recovery, economy and practicality, environmental protection.

Description

Comprehensive collecting and enlarging wind type pylon

Technical field: the utility model relates to the building formula pylon that is used to set up blower fan in a kind of wind-power generating system.

Background technique: the patent No. is 94229347.9 comprehensive collecting and enlarging wind type pylon, it is the center of four or six columns on square or Hexagon diagonal, erect, the fan house that evenly distributes and form between upper and lower two squares vertical with column or the Hexagon dividing plate longitudinally is arranged with collection expansion aerofoil between the bisector of lower clapboard in lower clapboard respective side on each fan house on to another.And last collection expands aerofoil and docks with next part expansion aerofoil two edges at top, forms the attic type space.Being provided with wind deflector in inner end one side constitutes.Though it is one that this building formula pylon has collection expansion wind, effectively improves the characteristics of wind energy utilization, because the collection of this pylon expansion air port is uncovered and column is a horn structure, prove through simulation, the building formula pylon of this structure exists windage and distinguished and admirable disorderly phenomenon, and wind speed is reduced, and wind shape is bad.Utilization ratio of wind energy can not reach very good effect.

Summary of the invention: the purpose of this utility model is for a kind of comprehensive collecting and enlarging wind type pylon is provided.Mainly be windage and the distinguished and admirable disorderly phenomenon that exists in the prior art in order to solve, improve effectively that wind wind-force when expanding the air port through collection is obstructed, wind speed reduces and the bad problem of wind shape, so that fan house obtains bigger wind energy, more effectively improve utilization ratio of wind energy.

Scheme of the present utility model is as described below: this model utility is included in the loft that fan house that the column erect on the square diagonal, dividing plate that column central authorities longitudinally distribute form and top blind flange are formed, and it is by the column that streamline Ji shape structure is set, the middle dividing plate that constitutes for axe-shape streamline one for the flat square body outside and sets up the active catch aerofoil constitute around fan house.

The beneficial effects of the utility model: this model utility is because structure and the prior art combination of having taked the column of streamline Ji shape structure, improved dividing plate and having set up the active catch aerofoil at the fan house wall, can not only effectively improve the windage phenomenon, make the wind speed that enters fan house obtain stable the acceleration, fan house will obtain the above wind speed of nature incoming flow twice, and along with increase highly, wind speed also increases exponentially thereupon.So just, can significantly improve wind energy utilization, obviously improve generating capacity.And this model utility can open or close the active catch aerofoil of the corresponding sidewall of fan house automatically according to the difference of wind direction, makes the wind that enters fan house form the single stably flow direction, more strengthened the raising of wind speed.Make design more be tending towards reasonable.That this model utility also has is simple in structure, be convenient to making, favourable use, save material, saves advantages such as taking up an area of, reduce investment, generated energy is big, the recovery rate is high, economical and practically, environmental, suitable promote, comprehensive benefit is remarkable.

Description of drawings:

Fig. 1 is the overall structure schematic representation of comprehensive collecting and enlarging wind type pylon;

Fig. 2 is the A-A sectional view of comprehensive collecting and enlarging wind type pylon;

Fig. 3 is the active catch aerofoil structural representation of comprehensive collecting and enlarging wind type pylon;

Fig. 4 is the active catch aerofoil control section schematic representation of comprehensive collecting and enlarging wind type pylon.

Embodiment: by Fig. 1-comprehensive collecting and enlarging wind type pylon shown in Figure 4 is that vertically respectively to erect its cross section on conplane square diagonal be that inside and outside two ends are wedge angles or interior for be the streamline Ji shape column 1 of circular arc outside the wedge angle, distributes the fan house 3 of several corresponding up and down dividing plates 2 formation along the longitudinal in the central authorities of four columns 1.Its central diaphragm 2 is flat square body in the middle of being, the outside is axe-shape streamline one and constitutes steel frame construction.The outside of dividing plate 2 all forms collection with 1 butt joint of corresponding column and expands the air port.Promptly be respectively equipped with active catch aerofoil 4 all around in each fan house 3 outside.Tower top at this multilayer architecture also is fixed with cover plate 5.Each collection expands active catch aerofoil 4 on air port and may be selected to be independently one or two (as Fig. 3) splitting, flexibly connect through door-hinge 6 and column 1, as adopt the switch of hydraulic mechanism control active catch aerofoil 4, should with its with hydraulic mechanism in telescopic boom 7 terminal fixing.Hydraulic mechanism is placed in the column 1, its control is top or the responsive fixedly wind transducer 8 of locating of wind direction that utilizes at this pylon, wind transducer 8 output is connected AD switching controllers (also being installed in the column 1) 9, again 9 outputs of AD switching controller with the control unit (as solenoid valve) of hydraulic mechanism be connected (as Fig. 4).Each control unit will be controlled the Push And Release of unidirectional active catch aerofoil plate 4 on this pylon.Certainly, the switch of this active catch aerofoil 4 also can be realized by the electronic alternate manner that waits.The utility model also can consider to be provided with fixing fan house sidewall according to the direction of local prevailing wind.Obtain bigger economic benefit with this.

The utility model is suitable to be erected at high-land, site that wind-force is strong, also it can be erected on island or the Plain, and strong middle samll cities and towns of wind-force or densely populated rural area, the high-altitude natural wind can not only be made full use of, save the energy and can avoid urban air pollution, benefit the nation and the people.Should be fixed on the vertical pivot blower fan in column 1 central authorities' each layer fan house 3 during installation, when natural wind blows, by wind transducer 8 wind direction signals is inserted AD switching controller 9 and carry out digital translation, insert the control unit of hydraulic mechanism then, under the control of control unit, the telescopic boom 7 of hydraulic mechanism is reliably flexible, force the fan house 3 and the active catch aerofoil 4 of prevailing wind respective side to be opened, and the active catch aerofoil 4 of another respective side is closed.When natural wind expanded the air port by column 1 and collection, wind speed obtained stable the acceleration, made fan house 3 obtain the above wind speed of twices and along with the increase of height, wind speed also increases exponentially thereupon.Be converted to output power through blower fan again.In addition, column 1 of the present utility model can be set to produce, the life zone, rationally realizes the comprehensive utilization of this pylon, has remarkable economic efficiency and social benefit.
