The positioning hole (102) is provided, the positioning column (202) is slidably arranged on the inner side of the positioning hole (102), the top of the pile column (100) is provided with sixteen groups of inclined slots (103), the guiding inclined block (401) is movably arranged on the inner side of the inclined slots (103), a positioning opening (104) is provided on a side of the inclined slots (103) close to the positioning hole (102), and the fan-shaped positioning block (400) is flipped and inserted into the inner side of the positioning opening (104).

10. The method for adjusting an adjustable fan installation device according to any one of claims 1 to 9, characterized in that: The adjustment method is as follows: The guide assembly (002) is hoisted to the top of the pile (100) by the suspension device, and the fixing ring (505) is installed on the top of the pile (100) by using a bolt structure. Then, the suspension device lifts the stabilizing assembly (001) and cooperates with the staff to assist in inserting the positioning column (202) into the inner side of the positioning hole (102), while keeping the guide inclined block (401) stably embedded in the inner side of the inclined slot (103). During the downward movement, the inclined surface will squeeze the fan-shaped positioning block (400) into the interior of the guide inclined block (401). When the combined plate (201) is in close contact with the top of the pile (100), the fan-shaped positioning block (400) will lose its restriction, and the internal support spring (404) will push the fan-shaped positioning block (400) to flip along the fixed axis (402). During the flipping process, the fan-shaped positioning block (400) will be embedded in the inner side of the positioning slot (104) to be locked. A hydraulic drive device is used to connect to each group of hydraulic cylinders (200) in a corresponding manner, and adjustment is performed by controlling the extension of the telescopic rod at the output end of the hydraulic cylinder (200). The flip support rod (206) is adjusted by pushing to flip along the auxiliary limit axis frame (205). The flip can adjust the position of the connecting shaft (207). The two groups of elastic pull belts (306) will pull the adaptive guide plate (300) to keep the adaptive guide plate (300) in an inclined state. The adjustment needs to ensure that when the adaptive guide plate (300) is in a vertical state, the adaptive guide plate (300) will be close to the outer wall of the combined tower (502); The combined tower (502) is lifted by the suspension device and moved to the top of the pile (100), then centered and slowly lowered. During the lowering process, the combined tower (502) will first contact the middle area of ​​the adaptive guide plate (300), and then continue to lower. Under the action of squeezing, the adaptive guide plate (300) will automatically flip along the connecting axis (207). During the flipping process, the adaptive guide plate (300) is kept close to the surface of the combined tower (502) and in a vertical state. At the same time, the adaptive guide plate (300) will automatically stick to the combined tower (502) and squeeze the elastic band (304) to produce deformation. At the same time, the adaptive guide plate (300) will flip along the limiting sleeve (302) to adjust the angle. During the continuous and stable downward movement, the sliding column (504) will first contact the guide arc frame (500) and slide. During the falling process, the sliding column (504) will automatically adjust along the guide arc frame (500) and enter the inner side of the U-shaped bracket (509). During the continuous downward movement, the hole at the bottom of the connecting plate (501) and the fixing screw (106) are kept combined. Finally, the nut is installed in a restricted state to lock it, and finally each group of components is removed.
