Description
Technical field
The utility model belongs to automatic control technology field, and in particular to a kind of novel rotor and new and effective wing fan.
Background technique
Modern society's promotion low-carbon environment-friendly is energy saving, and energy conservation and environmental protection becomes now public's focal issue.Common electric fan
Air-flow is instigated and provides wind for people, to reduce temperature.Blade high-speed rotation, since blade has certain angle (screw pitch),
So ambient gas is pushed, one speed of gas is given, to generate wind.
In order to enable efficiency reach higher, i.e., in the constant situation of power consumption, ventilation quantity is maximum.People inappropriate must not slow down paddle
Leaf revolving speed, so that air-flow be allowed more to flow according to the direction that people are expected.When propeller high-speed rotation due to blade height
Speed movement, different air pressures can be generated on blade two sides, hyperbar can generate " tip vortex " in the wing tip of blade.Similar to height
Eddy current effect caused by fast aircraft, this vortex can be such that airplane ascensional force reduces suddenly, and it is dangerous to generate air crash.Similarly fan spiral
Paddle can generate vortex in fan blade tip, and the forward power of air can be made to reduce suddenly, cause fan aspect of blowing efficiency low.It expends big
Measure electric energy.Revolving speed is reduced simply and increases blade dimensions, can weaken low efficiency problem to a certain extent.Field but more
We do not need oversized dimensions blade for institute, and need high-revolving propeller.
Utility model content
The technical problem to be solved by the utility model is in view of the above shortcomings of the prior art, provide one kind to reduce
Influence of the tip vortex to the main wing structure of high-speed motion, so that the power utilization rate of power mechanism output is mentioned when in use
High new and effective wing fan.
In order to solve the above technical problems, the technical solution adopted in the utility model is, a kind of novel rotor, including main wing,
Clamping circular arc body and end plate, main wing are the narrow strip of the wide other end in one end, and the upper surface of main wing is the arc-shaped of intermediate projections,
Lower surface is planar；The prominent outside integrally connected of the circular arc of the wide end of main wing and the clamping circular arc body, the narrow end of main wing and end
Plate integrally connected, and it is perpendicular with end plate, clamping circular arc body is for being mounted on shaft.
Further, which is " V " shape, and the open end of " V " shape is towards the side of main wing, and intermediate portion and master
The wing is connected；In rotation, the direction of the end direction rotation of " V " shape.
Further, the circular arc of the clamping circular arc body is 120 degree.
The invention also discloses new and effective wing fans, include novel rotor described in above-mentioned three, wherein three institutes
It states clamping circular arc body and joins end to end and connect, to form the annulus being sheathed in shaft.
The utility model has the advantages that the influence for reducing tip vortex to the main wing structure of high-speed motion, so that
The power utilization rate of power mechanism output is improved when in use.Make maintenance more in such a way that three monomers are used in combination
Change more convenient, air drag when normal operation greatly reduced for the interference in air flow of decrease so that electric energy or its
The utilization rate of power improves.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of novel rotor in the utility model.
Wherein: 1. main wings；2. clamping circular arc body；3. end plate.
Specific embodiment
A kind of novel rotor of the utility model, as shown in Figure 1, including main wing 1, clamping circular arc body 2 and end plate 3, main wing 1 is
The narrow strip of the wide other end in one end, the upper surface of main wing 1 are the arc-shaped of intermediate projections, and lower surface is planar；Main wing 1
The prominent outside integrally connected of the circular arc of wide end and the clamping circular arc body 2, the narrow end and 3 integrally connected of end plate of the main wing 1, and with
End plate 3 is perpendicular, and the clamping circular arc body 2 is for being mounted on shaft.End plate 3 is " V " shape, and the open end direction of " V " shape
The side of main wing 1, and intermediate portion is connected with main wing 1；In rotation, the direction of the end direction rotation of " V " shape.At a high speed
A large amount of vortex are had when rotation and flow to upper surface from 1 lower surface of main wing, and the generation with aircraft wing tip vortex, principle is similar.
This vortex is not required for us and to influence inefficiency when power consumption makes electric fan high-speed rotation.End plate 3 is set
It is set to " V " shape, flow perturbation of the tip vortex to 1 high-speed cruising of main wing when is greatly reduced, improves efficiency.Clamping circular arc
The circular arc of body 2 is 120 degree.
The invention discloses new and effective wing fans, include a kind of three above-mentioned novel rotors, wherein three clamping circles
Arc body 2, which joins end to end, to be connect, to form the annulus being sheathed in shaft.The mode of welding can be used, if after welding integral annulus
Inner hole is less than the fan diameter of axle, can suitably machine reaming.According to conventional fan Starting mode after assembling, it is not necessarily to other
Repacking.Make maintenance replacement more convenient in such a way that three monomers are used in combination, the interference in air flow of decrease is dropped significantly
Low air drag when operating normally, so that the utilization rate of electric energy or its power improves.On clamping circular arc body 2 directly
The fixation hole for being suitble to existing aid device is opened, three are directly loadable into driving device and directly use for one group, and when high speed is more common
Flabellum power is more powerful and power consumption is constant.
