[0002] Wind power generation refers to converting the kinetic energy of wind into electric energy. Wind is a kind of energy without public hazards, and the use of wind power generation is very environmentally friendly, and the electric energy generated is very huge, so more and more countries pay more attention to wind power generation.

[0003] The wind power tower is mainly used to support the high-rise steel structure of the wind turbine generator set, which is generally a column structure (hollow inside) formed by splicing multiple cylinder sections. The current installation support mechanism generally pours a concrete foundation on the ground, pre-buries a pouring screw on the concrete foundation, and welds a flange at the end of the wind power tower cylinder. When installing the support, the wind power tower cylinder is first erected on the concrete foundation, and the pre-buried screw is movably penetrated through the mounting hole of the flange, and then a nut is used for fixation, so that the wind power tower cylinder and the concrete foundation are rigidly connected. However, there is a lack of a buffering and damping mechanism.

[0035] As Figure 7 shown, in some embodiments, the boss 2 is provided with a plurality of ring-shaped slots 9, a plug rod 10 is movably arranged in the slot 9, and a third spring 11 is connected between the plug rod 10 and the inner wall of the slot 9. The end of the plug rod 10 away from the slot 9 abuts and overlaps with the mounting plate 5. Through the plurality of slots 9, the plug rod 10 is arranged in the slot 9, and under the elastic resistance of the third spring 11, the plug rod 10 supports the bottom of the mounting plate 5. The plurality of plug rods 10 form a ring-shaped support surface, thereby improving the stability of the mounting plate 5. When the wind tower 7 does not sway, the mounting plate 5 is in a horizontal state, ensuring that the wind tower 7 is in a vertical state, avoiding the center of gravity from shifting. When the wind tower 7 sways, the mounting plate 5 also squeezes the plug rod 10, so that the plug rod 10 squeezes the third spring 11.

The plurality of arc-shaped plates 15 are connected with the mounting plate 5 through the telescopic support 16. When the wind tower 7 is installed, the telescopic support 16 is adjusted first, so that the plurality of arc-shaped plates 15 slide away from each other. Then the wind tower 7 is fixed on the mounting plate 5. After the wind tower 7 is fixed, the telescopic support 16 is adjusted again, so that the plurality of arc-shaped plates 15 slide close to each other and are attached to the wind tower 7. The telescopic support 16 supports the arc-shaped plate 15. The arc-shaped plate 15 is connected with the mounting plate 5 through the sliding cooperation of the T-shaped block 14 and the T-shaped slot 13. The plurality of arc-shaped plates 15 enclose and fix the wind tower 7 to increase the connection strength between the wind tower 7 and the mounting plate 5, so that the wind tower 7 will not crack and break at the connection point with the mounting plate 5 due to the swaying stress, thereby further improving the service life of the wind tower 7.

The free end of the support rod 20 is fixed to the mounting plate 5 by the cooperation of bolts 21 and nuts 22. When the clip 19 is sleeved on two adjacent clips 18, the end of the support rod 20 is fixed to the mounting plate 5 by the cooperation of bolts 21 and nuts 22. The support rod 20 can not only support the arc plate 15, but also pull the clip 19 to prevent it from being lost.

[0042] like Figure 7As shown, in some embodiments, the inner wall of the first arc-shaped groove 3 is provided with an annular oil storage groove 23, the boss 2 is provided with an oil injection hole 24 in communication with the annular oil storage groove 23, the first sphere 4 plays a major role in bearing, through the annular oil storage groove 23, through the oil injection hole 24, lubricating oil is injected into the annular oil storage groove 23, so that when the wind power tower 7 shakes, the first sphere 4 rolls along the first arc-shaped groove 3 more smoothly, and the damping support 8 has a good buffering and damping effect on the shaking force.
