Abstract
The utility model is related to a kind of Novel rotary fan blade, including fix bar, and fix bar is provided with speed setter, and speed setter is provided with warning device, and fix bar one end is fixedly connected with rotating shaft, and rotating shaft is provided with blade, is in 45 ° between blade and rotating shaft.The utility model is simple in construction, and intensity is good, high temperature resistant; anti-oxidant, the pressure of rotating shaft is effectively alleviated in constant speed rotation; rotating shaft is preferably protected, is increased the service life, such as failure; and alarm, reduction loss, add deep bead; reduce resistance; increase the flow of fan blade, reduction energy infringement improves overall economic efficiency.
Description
Technical field
The utility model is related to a kind of Novel rotary fan blade.
Background technology
Fan blade generally comprises the fixed seat at the center of being located at and the blade being located at around fixed seat, fan blade of the prior art
Blade is usually to be made of iron plate in uniform thickness, generally smooth straight line or curvilinear structures.Using this structure,
When fan blade is rotated, wind is easily spilt from the outward flange of blade, drains to side, thus cause the flow of the positive wind of fan blade compared with
It is small, and insufficient strength, easy damaged blade, greatly, spilling spark, easy damaged fan blade, is improved at reduction of service life frictional resistance
This.
Utility model content
The purpose of this utility model is a kind of Novel rotary fan blade, to solve existing technical problem.
To achieve the above object, the utility model provides following technical scheme：A kind of Novel rotary fan blade, including fixation
Bar, fix bar is provided with speed setter, and speed setter is provided with warning device, and fix bar one end is fixedly connected with rotating shaft, and rotating shaft is provided with
Blade, is in 45 ° between blade and rotating shaft.
Further improvement of the utility model is：Rotating shaft and blade are made of chromium manganese nitrogen silicon heat-resistance steel material, blade
Shared 3-6, its surface is in micro- S shapes.
Further improvement of the utility model is：Blade tip is vertically provided with deep bead.
Further improvement of the utility model is：Fixed before and after rotating shaft by safety fixing fastener, surface scribbles anti-skidding exhausted
Edge coating.
Compared with prior art, the beneficial effects of the utility model are：
The utility model is simple in construction, and intensity is good, and high temperature resistant is anti-oxidant, constant speed rotation, effectively alleviates the pressure of rotating shaft,
Rotating shaft is preferably protected, is increased the service life, such as failure, and alarm, reduction loss adds deep bead, reduces resistance, increases
The flow of big blade, reduction energy infringement, improves overall economic efficiency.
Brief description of the drawings：
Fig. 1：Structural representation of the present utility model
Label in figure：1- fix bars, 2- speed setters, 3- warning devices, 4- rotating shafts, 5- blades.
