Fan cabin cover opening device and opening method thereof

Abstract

The invention belongs to the field of power generation fans, and particularly discloses a fan cabin cover opening device and an opening method thereof. The fan cabin cover opening device comprises a fixed stand column, a cabin cover opening mechanism and a control box; the fixed stand column is used for being fixed to the bottom of a cabin, and the cabin cover opening mechanism is arranged on thefixed stand column and comprises a deflection oil cylinder base, a deflection assembly and a jacking assembly; the deflection oil cylinder base is installed on the top side portion of the fixed standcolumn, the deflection assembly is provided with a first deflection oil cylinder and a second deflection oil cylinder, the second deflection oil cylinder is installed on the deflection oil cylinder base, and the end of a piston rod of the second deflection oil cylinder is connected with an oil cylinder middle base; the jacking assembly is used for jacking a cabin cover and comprises a jacking oilcylinder base, a first jacking oil cylinder and a second jacking oil cylinder. According to the opening device, the cabin cover of the fan can be conveniently opened, the maintenance time is short, the cabin cover of the fan can be conveniently and economically opened, land wind power does not need to rent a large crane, offshore wind power does not need to rent a large ship and an offshore crane,and the using effect is good.

Description

technical field [0001] The invention relates to the field of power generating fans, in particular to a device for opening a fan nacelle cover and an opening method thereof. Background technique [0002] Wind energy is a clean and pollution-free renewable energy source. It has been used by people for a long time, mainly through windmills to pump water and grind flour. With the continuous advancement of science and technology, wind power generation is currently the highest utilization rate of wind energy. The basic principle is to convert the kinetic energy of the wind into mechanical kinetic energy, and then convert the mechanical energy into electrical energy. The most common equipment used in wind power generation is wind turbines, that is, large fans. In order to make better use of wind energy, large fans Each component is very bulky, heavy, and the tower is high. Therefore, when the components in the fan are aging, the fan components need to be replaced and repaired. The...

Problems solved by technology

[0003] Many old-fashioned wind turbines currently in operation did not consider how to easily open the nacelle cover when they were designed. At present, the general method is to rent a crane, but renting a large crane is expensive and covers a large area. Sometimes it is necessary to destroy vegetation. Wind turbines need to rent large ships and offshore cranes to open the nacelle cover, which is greatly affected by sea conditions and weather, and the maintenance time is very long and the cost is high
