Described generator housing is flat-shaped after front circle, anterior half outer surface of ball is surrounded around its axis by semicircle shape bus, the rear curved surface of generator housing, be surrounded around the axis of generator housing by bus, namely generator housing is by anterior semicircle shape element line and the tangent fairing housing formed of rear curved surface element line.It is spherosome that this generator housing is often referred to front end, and rear end is the plane section perpendicular to axis, and fairing no longer extends back.
Described generator housing is flat-shaped after inner cone, is be coniform plain line and the rear curved surface element line tangent fairing housing formed by front portion.That is at pipeline fluid Way in, namely generator housing front portion is in coniform, and rear portion becomes fairing curved surface, and front portion and external rear face are in the fairing be smoothly connected.It is cone that this generator housing is often referred to front end, and rear end is the plane section perpendicular to axis, and fairing no longer extends back.
Outer surface front ends to the posterior end of described generator housing is pointed fairing after front circle.The generator housing of this fairing, makes form drag decline to a great extent.
Outer surface front ends to the posterior end of described generator housing is pointed fairing after inner cone.Namely anterior in coniform housing, be tending towards pointed housing by fairing and rear portion and be smoothly connected, the generator housing of this fairing, form drag can be made to decline to a great extent.
The utility model is by the design to generator body shape, the housing of original cylindrical power generator, class rectangular power generation machine is carried out fluidization design, significantly reduce form drag impact in the duct, make pipeline fluid speed while relatively improving, can effectively improve fluid motion speed, make fluid dynamic energy change into required electric energy better.The utility model is applicable to gas and fluid pipeline, can be arranged on the places such as water meter, threeway, elbow, joint.
