Description
Technical field
The utility model relates to blower fan tower barrel linkage structure.
Background technique
Wind energy is as a kind of clean renewable green energy resource, and blower fan is the dynamic power machine of mechanical energy by Wind resource change, and in a broad sense, it is a kind of is thermal source with the sun, take air as the heat energy utilization motor of working medium.The principle of wind-power electricity generation, is utilize wind-force to drive air vane to rotate, then the speed rotated is promoted by booster engine, impel electrical power generators.
In Large-scale Wind Turbines, pylon is as main bearing structure, bear load nearly all on blower fan, comprise the deadweight in cabin, cabin centre-of gravity shift and cause eccentric moment, wind end thrust moment of flexure that pylon is formed, also comprise that fitful wind inequality formed to the moment of flexure of pylon, the vibration of wind-driven generator etc.And these load all will pass to adpting flange and bolt by pylon, this just proposes very high requirement to the connection of pylon.
Summary of the invention
The utility model, for the deficiencies in the prior art, improves a kind of structure simple, stable connection, the blower fan tower barrel adpting flange effectively increased the service life.
For realizing the utility model object, provide following technological scheme: a kind of blower fan tower barrel adpting flange, be arranged at upper and lower tower cylinder connecting end, it is characterized in that comprising three coordinates flange part, described flange part I is a ring body, inner wall of ring body midline is provided with the bulge loop extended to the center of circle, the end of upper tower cylinder and the upper end of lower tower cylinder are all inserted in flange part I, both separate by bulge loop, upper and lower tower drum outer wall is identical with flange part I inner wall of ring body radian and be bolted connection, flange part II, III for symmetrical cross section be the annulus of L shape, flange part II, III upper and lower end being arranged at bulge loop respectively, flange part II, III comprises vertical circular arc anchor ring and horizontal end face, vertical circular arc anchor ring outer wall and upper and lower tower cylinder inwall coordinate and bolt is connected, horizontal end face is fixedly connected with bulge loop bolt.
As preferably, flange part II, III is vertical is evenly equipped with reinforced rib between arc surface and horizontal end face.
As preferably, the ring body upper and lower end of flange part I, II, III is provided with the otch of inclination, for locating with the spot welding of tower cylinder barrel.
As preferably, the attachment hole corresponding or setting of staggering mutually that flange part I, II, III ring body is offered.
The utility model beneficial effect: the utility model substantially increases join strength, extends working life, and structure is simple, with low cost.
