Description
Technical field
the present invention relates to a kind of screw type wind-driven generator.
Background technique
existing wind-driven generator comprises these two kinds of horizontal axis wind-driven generator and vertical axis aerogenerators.Wherein, the running shaft in horizontal axis wind-driven generator is parallel with wind direction, at the front end of running shaft, the blade-carrying wind wheel being limited by wheel hub is installed.Because wheel hub is the different hollow ball-shape body of thickness, quality is conventionally 15 tons of left and right, and whole wheel hub inner chamber is made up of 4 cores, makes casting hub cost higher, makes technique in this kind of generator very complicated, and vertical axis aerogenerator is mainly divided into resistance type and lift-type, wind wheel running shaft in these two types all adopts the structure perpendicular to ground, resistance type wind-driven generator be wherein utilize air flow through blade produce resistance as driving force, lift-type wind-driven generator be utilize air flow through blade produce lift as driving force, for resistance type and lift-type wind-driven generator, because the blade of resistance type is in rotary course, can be along with the increase resistance of blade rotational speed sharply reduces, and lift-type reverse side can increase, therefore the efficiency specific resistance type of lift-type wind-driven generator is high.Another problem is, although lift-type wind-driven generator comparative resistance type has higher output power, but the curved vane section being adopted by blade is thereon aerofoil profile, the size of blade is directly proportional to its output power, and the area of blade is larger, this kind of wind-driven generator more need very large wind-force to be driven, so can only be placed on the region of large wind-force.
the name of Chinese patent 201963476U notice of authorization is called proposition in " a kind of vertical axis wind turbine ", and this wind wheel comprises the rotor shaft of vertical shaft and is arranged on the spiral blade on this rotor shaft, and the spiral angle of single-piece blade is 90-180 degree.Its meaning is to increase by the blade of lightweight the effect that frontal resistance produces, to realize breeze-starting.Rotor shaft one end of this kind of generator directly or by driving component drives generator shaft to rotate, the size of its output power is also to rely on the area of blade to decide, but because can making rotor shaft under the effect of wind-force, blade produces axioversion power, particularly when blade radially area is larger time, its suffered axioversion power is larger, for fear of rotor shaft skew, can only stabilizing member be set in its one end, thereby make rotor shaft produce relatively large resistance, and then affect its output power; In addition, one end drive motor of rotor shaft rotates, and also can increase its resistance, so when the fabricating cost of the wind-driven generator of this kind of structure is higher, its output power is also relatively low.
summary of the invention
the object of this invention is to provide a kind of mode of utilizing vertical transferring power and solve that resistance is large and fabricating cost is high and the screw type wind-driven generator of complex structure and other problems.
screw type wind-driven generator proposed by the invention comprises screw rod and for limiting the supporting component of screw position, and transmission device, described transmission device comprises that the endless belt contacting with motor shaft and one end of being limited by supporting component are arranged on the driving component on this endless belt, and the other end of this driving component can be overlapped on screw flight in the time of vertical movement.The upper end portion of described screw rod is provided with bearing, be separately installed with on the both sides of this bearing outside and the top of screw rod be isosceles triangle for supporting the upper moving runner of endless belt or being separately installed with moving runner in the both sides of this bearing outside, the both sides of described bearing are provided with rectangle rack, in the outer end of each rectangle rack, moving runner on is installed, and in the end of rectangle rack, the bending part for turning round driving component is installed.
described screw rod is made up of two screw threads in the same way.
described supporting component has the support for the flat plate on top under supporting screw and support plate part, and is arranged on flat plate bottom and is separated with two lower moving runners of certain distance, and makes two lower moving runners and motor shaft be isosceles triangle.The central region of described flat plate is provided with the smooth recess for supporting screw lower end.
the top of described screw rod is provided with rotation blade.Screw tip is installed the rotating speed increase that pivoting leaf sector-meeting makes screw rod.
lead angle on described screw rod is 45 degree.If lead angle is greater than or less than 45 degree, all can make the resistance of driving component increase.Described screw rod adopts intermeshing twin-screw.
screw type wind-driven generator proposed by the invention only adopts screw rod supporting component, and this three part of transmission device, screw rod wherein also easily rotates under micro-wind action, and its rotating speed is directly proportional to wind speed, so, this kind of generator is not only simple in structure, and fabricating cost is low, and it is very high to convert the efficiency of electric energy to by wind energy; In addition, because screw rod bottom limits its position by smooth recess, upper area limits its position by bearing, and the mode that this kind limits its position is similar to gyro, very little to the resistance applying of screw rod, and it just can be rotated under very little wind-force effect.
