Detailed description of the invention
Below the structure of the present invention is illustrated.
As it is shown in figure 1, the present invention includes tower body, upper tower window, lower tower window, top cross-arm, bottom cross-arm, two ground wires
Support, is fixed on tower body top bottom lower tower window, bottom transverse load is horizontally placed on lower tower window top, and top cross-arm is arranged at tower
Window top, and top cross-arm and bottom cross-arm be made up of the limit cross-arm of the middle cross-arm and middle cross-arm both sides that are positioned at centre.
Described upper tower window is enclosed by top cross-arm, bottom cross-arm, two pillars between top cross-arm and bottom cross-arm
Become.Described lower tower window is made up of bottom cross-arm, cranking arm of be symmetrical set two inclinations, and said two lower end of cranking arm connects
Together, upper end is separately so that being hollow out in the middle part of lower tower window, upper end is opening shape.Tilt cranks arm two tower windows self
The gravity that gravity and two tower windows bear, is delivered to the top of tower body, and then makes overall being subject to of described wineglass tower along oblique line
Mechanical compliance profit is transferred on tower body, makes the stress of described wineglass tower more reasonable, and structure is more stable.Additionally, such design knot
Structure so that the Openworks shape structure in the middle part of lower tower window is bigger so that gas is bigger by area, and tower window is less to the obstruction of air-flow,
And make the support scope of tower window more greatly without increasing the wind surface of described wineglass tower entirety so that the structure of described wineglass tower
In addition to simpler, also there is good wind resistance, also further increase the wind resistance of the present invention.The ground wire stretched out props up
Frame is avoided that ground wire directly contacts with upper tower window and occurs damaging.
Described tower body is that described wineglass tower provides installation and supports pedestal.
Having a loop on the cross-arm of described top, A, B, C three-phase in this loop is horizontally arranged, and the most biphase limit that hangs over is horizontal
In load, an other phase hangs on middle cross-arm, and three-phase puts in order indefinite.Such as, biphase point of A, C hangs over two of top cross-arm
On the cross-arm of limit, B phase hangs on middle cross-arm, or biphase point of A, B hangs on two limit cross-arms of top cross-arm, during C phase hangs over
