Detailed Description
The embodiment is a wind power generation tower with an internal connection device, wherein the internal connection device is arranged in a tower barrel of the wind power generation tower at a connection position corresponding to two adjacent tower barrels up and down.
The inner connecting device in this embodiment has a reinforcing ring, on which 6 evenly distributed flange connections are fixed. In the embodiment, the two reinforcing rings are distributed on the upper side and the lower side of the flange connecting piece and are connected through stud bolts II which sequentially penetrate through the upper reinforcing ring, the flange connecting piece and the lower reinforcing ring and matched with nuts. The reinforcing ring is formed by splicing two semicircular reinforcing steel plates, and the reinforcing steel plates are Q235 common carbon structural steel plates with the thickness of 12 mm.
In the embodiment, the outer end of the flange connecting piece is provided with a bayonet, inner flanges of two adjacent tower drums corresponding to the upper section and the lower section are clamped in the bayonet of the flange connecting piece, and the connection is realized by matching nuts with stud bolts I which penetrate through the upper half part of the bayonet, the inner flange hole of the upper tower drum, the inner flange hole of the lower tower drum and the lower half part of the bayonet. Be equipped with the metal gasket between the bayonet socket and the inner flange of two sections adjacent tower section of thick bamboo about with, the metal gasket suit is on stud I, and the metal gasket reduces the clearance between bayonet socket and the inner flange, increases the inseparable degree of complex.
In the embodiment, the inner end of the flange connecting piece is provided with a vertically arranged mounting hole, and a rod piece is inserted into the mounting hole and is locked and fixed by a locking screw I. In this example, the middle part of the rod is fixedly connected with the flange connecting piece, and the upper and lower ends of the rod are respectively connected with the inner walls of the upper and lower tower drums through the tower drum connecting piece.
The tower tube connecting piece comprises a mounting pipe, a connecting plate and a rib plate for connecting the mounting pipe and the connecting plate, wherein the mounting pipe is sleeved on the rod piece and is fixed by a locking screw II; the connecting plate is welded and fixed on the inner wall of the tower barrel.
In this embodiment, the end face of the connecting plate contacting the inner wall of the tower barrel is a plane, a gap is formed between the plane and the inner wall of the tower barrel after butt joint, and the gap is welded and fixed after being filled with solder. The plane is easy to process, a larger gap is formed between the plane and the tower barrel, more welding flux is filled when welding is conducted, and welding connection is more stable and reliable. A groove is arranged on the plane of the connecting plate, and the groove is mainly designed to increase the filling amount of the solder.
