Abstract
The utility model relates to a fan blade, in particular to an adjustable fan blade suitable for occasions of high temperature, high corrosion and the like. At present, the fan blade is vertically fixed on a motor shaft, and the inclination angle of the fan blade is fixed and cannot be adjusted according to the magnitude of wind power required by fieldwork. The adjustable fan blade comprises a blade, a metal reinforcing plate is arranged in the blade made of fiber reinforced plastic composite material, a cylindrical fixed handle is arranged at one end of the blade, the tail of the cylindrical fixed handle is provided with a lug boss, and one side of the cylindrical fixed handle is provided with blade inclination scales. The fan blade is connected with the fan motor shaft by adopting a chuck, the inclination angle of the blade can be adjusted according to the magnitude of the wind power required by fieldwork, and a few conventional fans of different size can be replaced by the fan.
Description
Technical field
The utility model relates to a kind of fan blade, particularly a kind of adjustable fan blade that is applicable to occasions such as high temperature, high corrosion.
Background technique
The fan blade that uses at present mostly is that metallic material is processed, and is directly exposed to the outside, very easily suffers erosion in occasions such as high temperature, high corrosion; Working life is short; Need often to change, increase user cost and maintenance workload, also influence normal production work; Secondly fan blade all is directly to be fixed on the motor shaft, and its inclination angle is changeless, can not be according to work on the spot demand wind-force size adjustment blade tilt.
The model utility content
The utility model purpose provides a kind of adjustable fan blade that occasions such as high temperature, high corrosion, blade tilt can be adjusted according to work on the spot demand wind-force size that is particularly suitable for.
The utility model technological scheme: a kind of adjustable fan blade, comprise blade, in the blade that glass fiber reinforced plastics composite material is processed, be provided with metal reinforcing plates, an end of blade is arranged to cylindric fixing, and cylindric fixing is provided with boss to afterbody.
Fixedly be provided with the blade tilt scale to a side cylindric.
Arrange metal reinforcing plates along the whole length direction of blade.
The utility model adopts glass fiber reinforced plastics composite material to process fan blade, and the corrosive gas of occasions such as high temperature, high corrosion is difficult to corrode, and fan blade prolongs three to seven times than original metal blade working life, has reduced user cost and maintenance workload simultaneously; Fan blade adopts chuck to be connected with the fan motor axle, and blade tilt can be according to the adjustment of work on the spot demand wind-force size, and a typhoon machine can replace the different a few typhoon machines of life size to use.
Description of drawings
Accompanying drawing is the utility model structural representation.
1 metal reinforcing plates among the figure, 2 blades, 3 blade tilt scales, 4 cylindric fixing handles, 5 chucks, 6 chuck fixed holes.
Embodiment
The utility model adopts mould to annotate mode and metal reinforcing plates is arranged in the fan blade of glass fiber reinforced plastics composite material, arranges metal reinforcing plates along the whole length direction of blade, to guarantee blade strength.Blade one end is provided with cylindric fixing, tightens together with the motor shaft upper chuck of blower fan.Blade is cylindric fixedly to be provided with the blade tilt scale to a side; Can be according to work on the spot demand wind-force size adjustment blade tilt; Rotor blade is with regard to the adjustable blade inclination angle before fastening; Motor shaft upper chuck and the cylindric fixedly handle of blade with blower fan tightened together just (blade is cylindric fixing inserting the chuck fixed hole, and chuck two halves up and down passes through bolton) then.
