01811561.6 invention《Wind power installation》, Application No. 201010236404.2 invention《From the motion tracking wind direction tracking sun
Wind and light generating system》.
However, our Students ' Sci-tech Activities groups find when investigating the using energy source in the South Pole:Though the wind resource in the South Pole
It is so extremely abundant, but the electric energy in scientific investigation station is not but to utilize wind-power electricity generation, but generated electricity using diesel-driven generator, in the South Pole
Today that scientific investigation is carried out energetically, South Pole tourism continues to develop, diesel generation will not only consume substantial amounts of diesel oil, but also pollute ring
Border.
Our 12 grades of usually said typhoons, wind speed can reach 32.6 meter per seconds, enough bigCan be normal in the South Pole, wind speed
55.6 meter per seconds can often be reached, sometimes even up to 83.3 meter per seconds, so abundant wind resource, why not be used for generating electricity
The member of our Students ' Sci-tech Activities groups has found by research, although the strong wind weather in the South Pole is a lot, wind energy money
Source is very abundant, and still, because existing wind power generation plant is substantially made up of multi-disc flabellum, there is an axis centre, this
The wind power generation plant of kind structure uses the technological deficiency that exists and can not overcome as follows in the South Pole:When larger sand, stone grain are blown and beaten
When on the windward side of flabellum, the damage of flabellum can be caused;Especially in the weather of cold, larger snow grain is beaten at a high speed
Hit on the windward side of flabellum, its broken ice end can be adhered to the surface of flabellum, and the slowly accumulation at ice end is freezed, and flabellum is more next
It is heavier, the rotation efficiency of flabellum will be substantially reduced, slow accumulation of waiting a moment is freezed, and can also change the original windward side shape of flabellum
Shape, when the windward side of flabellum is no longer inclined smooth surface, wind (is actually blown in flabellum on the windward side of flabellum
On the ice sheet that windward side is freezed), the stress of flabellum is at random, can also substantially reduce the rotation efficiency of flabellum, even result in flabellum without
Method normal rotation.
The content of the invention
It is an object of the invention to provide a kind of differential pressure generating device, can avoid storm wind that larger sand, the piping and druming of stone grain exist
Flabellum is damaged on the windward side of flabellum;In the weather of cold, larger snow grain can be avoided to hit in flabellum at a high speed
Windward side on, overcome flabellum rotation efficiency reduce, even can not normal rotation technological deficiency.
To achieve the above object, the present invention adopts the following technical scheme that:
A kind of differential pressure generating device, including a cavity body, the top surface of the cavity body is convex cambered surface, and bottom surface is flat
Face, at least one Vertical Channel is provided with the middle part of the cavity body, wind power generation plant is provided with the Vertical Channel, it is described
Wind power generation plant includes being used for the flabellum for driving the wind power generation plant, and the axle center of the flabellum rotating shaft of the flabellum leads to vertical
The axis coinciding in road.
The wind power generation plant also includes generator, and the flabellum rotating shaft is rotated by speed changer and the generator to be connected
Connect.
The wind power generation plant is fixed in Vertical Channel by support bar.
At least one is hollow-core construction to the support bar, and the power transmission line and control line of the wind power generation plant are via this
The support bar of hollow-core construction electric component corresponding with outside Vertical Channel is connected.
The underrun support of the cavity body is fixed on ground.
It is rotatably connected between the cavity body and support by hinge, support is provided with wind direction tracking device.
A kind of differential pressure generating device, including a cavity body, the outline for stating cavity body longitudinal section are plano-convex aerofoil profile or bumps
Aerofoil profile, at least one Vertical Channel is provided with the middle front part of the cavity body, wind power generation plant is provided with the Vertical Channel,
The wind power generation plant includes being used for the flabellum for driving the wind power generation plant, and the axle center of the flabellum rotating shaft of the flabellum is with erecting
The axis coinciding of straight channel.
The wind power generation plant also includes generator, and the flabellum rotating shaft is rotated by speed changer and the generator to be connected
Connect.
The generator is fixed in Vertical Channel by support bar.
At least one is hollow-core construction to the support bar, and the power transmission line and control line of the wind power generation plant are via this
The support bar of hollow-core construction electric component corresponding with outside Vertical Channel is connected.
Compared with prior art the beneficial effects of the invention are as follows:Due to using above-mentioned technical proposal, the top of the cavity body
Face is convex cambered surface, and bottom surface is plane, the cavity body of this structure, when strong wind flows from the left end of cavity body to right-hand member,
According to bernoulli principle, (i.e. the flow velocity of fluid is bigger, and its pressure is smaller;Flow velocity is smaller, and its pressure is bigger), due to the cavity
The top surface of body is convex cambered surface, and bottom surface is plane, and the flow velocity below cavity body is less than the flow velocity of top, so that cavity body
The pressure of lower section is more than the pressure of top, generates pressure difference, and we set Vertical Channel in the middle part of the cavity body, under Vertical Channel
The pressure at end is more than the pressure of upper end, will produce the air-flow flowed up in Vertical Channel, the flabellum being located in Vertical Channel
It will be promoted and rotate by air-flow, so as to drive wind power generation plant to generate electricity, because Vertical Channel is perpendicular to the bottom surface of cavity body, this
The structure of sample makes the TRT to avoid storm wind by larger sand, the piping and druming of stone grain in flabellum directly facing snowstorm
Flabellum is damaged on windward side;In the weather of cold, larger snow grain can be avoided to hit in flabellum at a high speed windward
On face, so as to avoiding accumulated snow from freezing on flabellum windward side, overcome flabellum rotation efficiency reduce, even can not normal rotation
Technological deficiency.It is adapted to use in the environment that summary is extremely disliked in the South Pole.
