Detailed Description
The invention is described in further detail below with reference to the following detailed description and accompanying drawings:
referring to fig. 2, the fan installation method includes the following steps:
1) in the embodiment, the tower barrel 100 has three sections, in order to assemble the sections, three sections of barrels are required to be arranged on a movable carrier respectively, then a clamp is arranged on the carrier, the height of each section of barrel is adjusted to enable the axes of the three sections of barrels to be at the same height, then the carrier is started to enable the axes of the three sections of barrels to be at the coaxial position, the three sections of barrels are close to each other until the end faces of the three sections of barrels are in contact with each other, and a worker completes the assembly of the tower barrel by screwing bolts between the sections of barrels. The axis of the assembled tower is in a horizontal state.
After the tower barrel is assembled, the engine room 101 is installed at the top end of the tower barrel, the installation process is similar to that of the tower barrel, the engine room is moved to the top of the tower barrel (the top where the tower barrel is vertically arranged) through the carrier, then the installation surface of the engine room matched with the top of the tower barrel is attached to the tower barrel, then the installation of the engine room is completed by screwing bolts of workers, and generally, as long as no accident occurs during installation, all the installation surfaces of the engine room can be ensured to be in the vertical position after installation.
2) The blades 103 are installed on the three installation surfaces of the nacelle 101, and when the installation is carried out, one blade is transported to the side surface of the nacelle by a carrier, after the installation is finished, the blades are rotated, the next installation surface reaches the position before the installation surface of the previous blade is installed, and then the installation of the next blade is finished until the installation of the three blades is finished. The installed blade is located above the tower, so that the blade does not contact the ground when the next rotation is performed.
3) The tower 100 is hinged at one end to the base 102, and the bottom of the tower of a typical wind turbine has no special hinge mechanism, and in order to meet the requirements of all conventional wind turbine installations, we have developed a mounting fixture, which we will describe in detail in the embodiments of the fixture. Of course, the tower and the base can be modified except by using the special clamp produced by the user, and the hinge joint is not a difficult structure for anyone in any mechanical field.
4) Pulling the tower drum 100, allowing the tower drum 100 to rotate along a hinge point, gradually rotating to a vertical position, and pulling the tower drum to rotate by various structures, in this embodiment, a scheme of pulling by using ropes is adopted, specifically, a first rope 21 and a second rope 22 are tied up on the outer wall of the tower drum, the first rope 21 is driven by the first coiler 31, a straight line of a force application direction of the first rope 21 is located on a plane of a central axis in the tower drum rotation process, and the first rope pulls the tower drum 100 to reach the vertical position. The second rope 22 is driven by the second retractor 32, the second rope and the first rope are respectively located on two opposite sides of the tower drum, and the straight line of the force application direction of the second rope is located on the plane of the central axis of the tower drum rotation process. When a tower barrel is close to the vertical state, the tower barrel can fall to the vertical position from the inclined position due to the change of the gravity center, and in the time, the second rope is required to give a force in the opposite direction of the acting force of the first rope, so that the tower barrel cannot be in an accident during the steering vertical process. When the tower barrel is completely rotated to the vertical position, the installation surfaces of the tower barrel and the base are opposite, and the tower barrel is installed on the base by screwing bolts on the installation surfaces.
The steps of installing the tower barrel in the transverse direction, installing the cabin at the top of the tower barrel transversely arranged and installing the fan blades are not needed to lift the product to a high position, all the installation steps are carried out on the ground, so the influence of weather is small, the installation efficiency is greatly improved, in addition, in the whole process, the product is not needed to be lifted to a high position, a large-scale crane is also saved, and the installation cost is greatly reduced.
Referring to fig. 3 to 5, the fan installation jig includes two clamping bodies 4, one end of each of the two clamping bodies 4 is hinged to each other, one of the clamping bodies 4 is fixed to an outer ring of the base 102, and the other clamping body 4 is fixed to an outer ring of the tower 100.
