Abstract

The invention relates to a low-flow-rate no-load starting device for fans or tide power generation mechanisms and belongs to the field of power generators. The low-flow-rate no-load starting device is provided with a vane and a power generator and is characterized in that a photoelectric switch and a clutch are arranged between the vane and the power generator; the vane is connected with the clutch through a coupler; the clutch is connected with the power generator through another coupler; and the photoelectric switch is electrically connected with a singlechip. When the rotating speed of the vane is lower than a trigger rotating speed set by the clutch, the clutch is in an off state, and the vane is started at a low flow rate in a no-load manner; and when the rotating speed of the vane is higher than the trigger rotating speed set by the clutch, the clutch works and the vane drives the power generator to rotate to generate power.

Description

The low flow velocity No Load Start device that is used for blower fan, tidal power generating mechanism
Technical field
The present invention relates to electrical generator fields, especially a kind of low flow velocity No Load Start device that is used for blower fan, tidal power generating mechanism.
Background technique
As everyone knows, rotary electricity generating devices such as blower fan, trend ability generator all exist starting torque excessive all the time, and device starts the phenomenon of difficulty.After device starts because dynamic friction torque is little than static friction torque, so device can be under far below the speed of incoming flow that starts flow velocity proper functioning.This phenomenon has increased the requirement of rotary electricity generating device to speed of incoming flow greatly, and has significantly cut down the operation interval of device, and device can't be worked under low flow velocity.The method that solves this type of problem at present is to add motor in electricity generating device inside or make generator in starting process, serve as motor, drives device and starts.This method has increased device construction cost on the one hand, has reduced generating efficiency; Design difficulty and final-period management, maintenance cost have been increased on the other hand.
Summary of the invention
In order to overcome the deficiency of existing technology; The present invention provides a kind of low flow velocity No Load Start device that is used for blower fan, tidal power generating mechanism; When the rotational speed of blade is lower than the triggering rotating speed of clutch setting; Blade is No Load Start under low flow velocity, and when the rotational speed of blade was higher than the triggering rotating speed of clutch setting, blade drove the generator rotary electrification.
The technical solution adopted for the present invention to solve the technical problems is: a kind of low flow velocity No Load Start device that is used for blower fan, tidal power generating mechanism; Be provided with blade and generator; It is characterized in that optoelectronic switch and clutch are installed between blade and the generator, and blade links to each other through coupling with clutch; Link to each other through another coupling between clutch and the generator, be electrically connected between optoelectronic switch and the single-chip microcomputer.
The invention has the beneficial effects as follows that when the rotational speed of blade was lower than the triggering rotating speed of clutch setting, clutch was in off state, blade is No Load Start under low flow velocity; When the rotational speed of blade is higher than the triggering rotating speed of clutch setting, clutch work, blade drives the generator rotary electrification.
 
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is a structural representation of the present invention, also is a kind of embodiment's schematic representation.
Fig. 2 is the schematic representation of another embodiment of the present invention.
1. blades among the figure, 2. optoelectronic switch, 3. clutch, 4. generator, 5. single-chip microcomputer.
 
Embodiment
In Fig. 1; The present invention is provided with blade 1 and generator 4; Optoelectronic switch 2, single-chip microcomputer 5 and clutch 3 are installed between blade 1 and the generator 4; Blade 1 and clutch 3 link to each other through coupling, link to each other through another coupling between clutch 3 and the generator 4, are electrically connected between optoelectronic switch 2 and the single-chip microcomputer 5.Optoelectronic switch 2 adopts general fashion to be fixed on the axle between blade 1 and the clutch 3; Single-chip microcomputer 5 is installed between device inner vanes 1 and the clutch 3; The preferably selection input and the less type of output torque of clutch 3, moment is big more, and required speed of incoming flow is high more.
In Fig. 2; The present invention is provided with blade 1 and generator 4, and optoelectronic switch 2 and clutch 3 are installed between blade 1 and the generator 4, and blade 1 and clutch 3 link to each other through coupling; Link to each other through another coupling between clutch 3 and the generator 4, be electrically connected between optoelectronic switch 2 and the single-chip microcomputer 5.Optoelectronic switch 2 is fixed on the connecting plate of device front end, and single-chip microcomputer 5 is positioned on the outside control platform of device, and single-chip microcomputer 5 is electrically connected with optoelectronic switch 2 through the shielding wire connection.
When the present invention did not work when blade 1, clutch 3 was in off state.Along with the increase of speed of incoming flow, blade 1 begins to start the line space commentaries on classics of going forward side by side.The rotation situation of blade 1 is given to single-chip microcomputer 5 by optoelectronic switch 2 with the form of pulse signal, and calculates the rotational speed of blades 1 by single-chip microcomputer 5.When the rotational speed of blade 1 during greater than the setting working speed of clutch 3, trigger signal of power supply that single-chip microcomputer 5 is given clutch 3, clutch 3 is started working, and blade 1 drove generator 4 and generated electricity this moment.When speed of incoming flow reduced gradually, the rotational speed of blade 1 also can reduce gradually.When the rotational speed of blade 1 during less than the setting working speed of clutch 3, trigger signal of power supply that single-chip microcomputer 5 is given clutch 3, clutch 3 breaks off generator 4 generation outages.
