Air vent is led directly to along ventilating duct, air-flow fans the active force for applying deflection during wind-guiding fan is flowed through to wind-guiding, and wind-guiding fan will
Drive protection board rotation；The lasting rotation of protection board causes shade uniform sweep photovoltaic panel of the generation in photovoltaic panel, therefore
What photovoltaic panel was subject to everywhere in a cycle blocks more uniform, caused voltage difference relative equilibrium, when being not in local long
Between be blocked and excessive situation of generating heat, so as to effectively prevent the generation of hot spot effect.
In addition, when the height of lamp stand is higher, the draught head of lamp stand upper end and lamp stand bottom is larger, is imitated according to chimney
Should, stronger air-flow will be produced in lamp stand, so as to drive protection board to rotate at a high speed, therefore the present invention will have in actual use
Preferable effect；Meanwhile the present invention is used for the larger area of long-term wind-force and will also had a clear superiority.
Delicate structure of the present invention, old it is cheap, can effectively prevent hot spot effect, protect long-term, the stable fortune of photovoltaic panel
OK, maintenance cost is substantially reduced, value is applied clinically and popularized with higher.
Preferably, attach reflective membrane in the lower surface of the photovoltaic panel；In order to which the light for sending lamp body is pooled to down
Side, it is easy to vehicle and pedestrian to observe.
Preferably, wind deflector is installed in the air inlet；Air-flow around lamp stand can be imported institute by wind deflector
State in ventilating duct, so as to promote the rotation of protection board.
Preferably, on the protection board and the photovoltaic panel position face the permanent magnetism piece for being provided with homopolar-repulsion；
In order to reduce the resistance between protection board and photovoltaic panel, so as to promote the rotation of protection board.
Preferably, the top edge in the protection board also adds surveillance mirror, the reflecting surface direction of the surveillance mirror is protected
Backplate；In later maintenance, the dust that protection board upper surface only need to can be observed in staff by the reflection of surveillance mirror accumulates
Situation is deposited, specific aim cleaning is carried out to the photovoltaic panel that needs are cleared up；Without climbing one by one at the top of traffic lights, so as to reduce work
Difficulty, improve maintenance efficiency.
As further preferred, the surveillance mirror is convex reflecting mirror；It is larger in order to be obtained by less area
The visual field.
Brief description of the drawings
Fig. 1 is the structural representation of this self-cleaning photovoltaic traffic lights one embodiment.
