Background

Wind power generally refers to wind power generation, which refers to converting kinetic energy of wind into electrical energy. Wind energy is a clean and pollution-free renewable energy source, and is used for a long time by people, mainly pumping water, grinding surfaces and the like through windmills, and people are interested in how to use wind to generate electricity. The wind power generation is very environment-friendly, and the wind energy is huge, so that the wind power generation device is increasingly valued in countries around the world. The wind power generation is realized by converting the kinetic energy of wind into mechanical kinetic energy and then converting the mechanical energy into electric kinetic energy. The principle of wind power generation is that wind power is utilized to drive windmill blades to rotate, and then the rotating speed is increased through a speed increaser so as to promote a generator to generate electricity. According to the windmill technique, power generation can be started at a breeze speed (a breeze degree) of about three meters per second. Wind power generation is forming a hot tide in the world because the wind power generation does not need to use fuel and does not generate radiation or air pollution. The devices required for wind power generation are called wind power generation units. The wind generating set can be divided into three parts of a wind wheel (comprising a tail vane), a generator and a tower. The tower is a frame supporting the wind rotor, tail rudder and generator, which is generally built relatively high in order to obtain a large and uniform wind force, and which is sufficiently strong, the tower height is typically in the range of 6-20 meters, depending on the influence of ground obstructions on the wind speed, and the diameter of the wind rotor.

Taking a wind power tower hoisting device with the number of CN218664972U as an example, the application relates to a wind power tower hoisting device, which comprises hoisting blocks; the hoisting block is provided with a hoisting part and a fixing hole; the hoisting part is positioned on one side surface of the hoisting block, the fixing holes penetrate through the two opposite side surfaces of the hoisting block, the fixing holes are matched with the mounting holes of the wind power tower to be hoisted, and the fixing holes are of a slotted hole structure. The hoisting part is suitable for being connected with the hoisting block and the cable, the fixing hole is suitable for the hoisting block to be tightly installed on the wind power tower to be hoisted, and the bolt is screwed into the fixing hole and the wind power tower to be hoisted, so that the hoisting part can drive the wind power tower to be hoisted to move.

However:

the device structure can not conveniently hoist objects with different specifications, is inconvenient to fix, can not change the angle after hoisting, and is inconvenient to install.
