Abstract

The utility model relates to a horizontal windmill, in particular to an automatic windward horizontal windmill capable of directly transmitting mechanical energy. A first ratchet wheel and a first ratchet bar are used for limiting one rotating direction, relative to a stand column, of a windmill enclosure, and a second ratchet wheel and a second ratchet bar are used for limiting the other rotating direction, relative to the stand column, of the windmill enclosure; when load torque on a vertical shaft of a windmill is larger than torque on a wind rudder stock, the windmill enclosure is locked by the ratchet wheels and the ratchet bars, and therefore mechanical transmission between an impeller shaft and the vertical shaft can not lose efficacy. When the wind rudder stock swings relative to the enclosure according to the deviation of wind, a push rod on the wind ruder stock pushes the ratchet wheels and the ratchet bars which limit the enclosure turning to the windward rotation aside, and therefore the windmill enclosure rotates to be in the windward direction under the action of the wind rudder stock.

Description

A kind of automatic wind facing horizontal type windmill of directly transmit machine energy

Technical field

The utility model belongs to wind power utilization device field, is specifically related to a kind of automatic wind facing horizontal type windmill of directly transmit machine energy.

Background technique

Windmill is divided into horizontal type windmill and vertical windmill, and the impeller shaft of horizontal type windmill is horizontally disposed with, and the impeller shaft of vertical windmill vertically arranges.Under equal wind-force, the efficiency of the wind energy transformation mechanical energy of horizontal type windmill is higher than vertical windmill.Vertical windmill can be accepted the wind-force of any direction, and horizontal type windmill must be corrected by the wind direction rudder of afterbody the weather side of impeller.

Wherein, vertical windmill can directly be transmitted to millpost below by the mechanical energy of wind power transformation by the impeller shaft rotating, horizontal type windmill must pass to the mechanical energy of wind power transformation pivotal axis from horizontally disposed impeller shaft by orthogonal bevel gear set, then by the pivotal axis of rotating, mechanical energy is transmitted to millpost below.In the time that the moment of torsion on horizontal type windmill wind direction rudder is less than the load torque in pivotal axis, mechanical transmission between impeller shaft and the pivotal axis of horizontal type windmill will lose efficacy, show as pivotal axis and do not rotate, on the bevel gear of the bevel gear on impeller shaft in pivotal axis, roll, drive windmill to rotate around column.

For avoiding above problem, existing horizontal type windmill that can automatic wind facing is all that generator shaft is directly connected with impeller shaft, is electric energy by wind energy transformation, then by electric wire, electric energy is led to column below.In the time that needs drive some mechanical devices, also need electric energy to be converted into mechanical energy by motor, reduced the utilization ratio of wind energy, and generator must be arranged in the windmill on column top, be not easy to the maintenance of generator.The horizontal type windmill also having has simply been abandoned automatic wind facing function, make its reach direct transmit machine can requirement, but the increase of the drift angle between its utilization ratio box haul and its impeller shaft to wind energy and reducing.

Common super sized type wind motor for electric generation makes windmill automatic wind facing by wind vane and control system control, and the relatively middle-size and small-size windmill complicated structure of this automatic wind facing mode has increased the cost of windmill.

Model utility content

For above problem, the purpose of this utility model is to provide a kind of automatic wind facing horizontal type windmill of directly transmit machine energy, and it can directly drive the mechanical device or the generator that are positioned at column below, and does not affect the automatic wind facing function of horizontal type windmill.

For reaching above object, the utility model is achieved by the following technical solutions.

A kind of automatic wind facing horizontal type windmill of directly transmit machine energy, it is characterized in that, comprise column, be fixed on the pawl seat on column, be arranged on the casing on pawl seat, be fixed on the chassis backplane of casing lower end, from the impeller shaft passing in casing, be fixed on multiple blades of impeller shaft traversing through end, be fixedly set in the drive bevel gear at impeller shaft middle part, be arranged on the hinge base of casing rear end, be arranged on the limiting board of hinge base both sides, horizontally hinged wind rudder stock on hinge base, is fixed on the wind rudder sheet on wind rudder stock; Also comprise the pivotal axis that longitudinally runs through pawl seat, be fixedly set in pivotal axis top and engage with drive bevel gear by dynamic bevel gear;

On described pawl seat, fixed cover is equipped with the first ratchet and the second ratchet; The lower surface of described chassis backplane front end is hinged with the first ratchet bar engaging with the first ratchet and the second ratchet bar engaging with the second ratchet side by side; Described the first ratchet bar and the second ratchet bar are distributed in the both sides of pawl seat; The lower surface of described chassis backplane rear end is provided with spring seat, is connected with respectively the first extension spring of traction the first ratchet bar and the second extension spring of traction the second ratchet bar on spring seat; On described wind rudder stock, be fixed with two driving levers that stretch to respectively the first ratchet bar and the second ratchet bar; Described the first ratchet and the second ratchet radius are equal, and ratchet deflection is contrary; Ratchet on ratchet and the second ratchet bar on described the first ratchet bar all tilts to rounded end.

The feature of technique scheme and further improvement:

Between described pawl seat and casing, be fixed with bearing, between impeller shaft and casing, be fixed with bearing, between pivotal axis and pawl seat, be fixed with bearing.

Described the first extension spring is identical with the specification of the second extension spring, and natural length is less than the radius of the first ratchet and the second ratchet.

The beneficial effects of the utility model are to limit a sense of rotation of the relative column of windmill casing by the first ratchet and the first ratchet bar, by another sense of rotation of the second ratchet and the relative column of the second ratchet bar restriction windmill casing; In the time that the load torque in the pivotal axis of windmill is greater than the moment of torsion on wind rudder stock, make windmill casing locked by ratchet and ratchet bar, can not make the mechanical transmission between impeller shaft and pivotal axis lose efficacy.In the time that wind rudder stock swings according to the relative casing of the deflection of wind, the driving lever on wind rudder stock is pushed limit chassis aside and is turned to ratchet and the ratchet bar of direction windward, and windmill casing is just turned to direction windward under the effect of wind rudder stock.
