Description
Technical field
The utility model relates to a kind of solar collector, especially from the improvement of the mechanical driving device of motion tracking Solar sunlight collecting device, belongs to application of solar.
Background technology
Understand according to the applicant, existing daylighting lighting device from the motion tracking sun has two big classes: a class is to calculate the open-loop tracking device of daylighting lighting device movement locus around the day operation rule according to the earth; Another kind of is real-time detection sun position over the ground, and the control lighting equipment is to the closed loop tracking means of day angle.The latter generally includes the light signal feedback processing circuit of the optically focused lighting device that is installed on the saddle, the mechanical driving device that drives the motion of optically focused lighting device, control mechanical driving device, transmits the sun light tracking sensor of detectable signal to light signal feedback processing circuit.The application number that the main designer of the application proposes is 01113529.8 to have authorized application for a patent for invention " sunlight optical fibre illuminator " promptly to disclose above content.
The applicant finds that in practice mainshaft mechanism in the above patent and auxilliary axis mechanism exist mechanical clearance to be difficult to overcome, to keep in repair problems such as adjustment is inconvenient, simple and direct practicality is not enough, have carried out further improvement for this reason.
Summary of the invention
The purpose of this utility model is: at the deficiency that above prior art exists, propose a kind of simple and direct, stable, reliably, practical solar automatic tracking lighting device, thus it is applied conscientiously.
In order to reach above purpose, solar automatic tracking lighting device of the present utility model comprises optically focused daylighting element, drive the mechanical driving device of optically focused daylighting element motion, the light signal feedback processing circuit of control mechanical driving device, transmit the sun light tracking sensor of detectable signal to light signal feedback processing circuit, described mechanical driving device comprises mainshaft mechanism and the auxilliary axis mechanism that is superimposed upon on the mainshaft mechanism, its improvements are: during described main shaft uprightly is installed on the base of mainshaft mechanism, the upper end is connected with the U-shaped support, described optically focused daylighting element is installed in the front end of cylindrical shell, described auxilliary axle is connected with cylindrical shell, is supported on the U-shaped support.
Find out that easily drive mechanism of the present utility model is simple, machinery zero anufacturability is good, is convenient to eliminate the gap, and stable working is reliable, therefore can apply conscientiously.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is the structural representation of the utility model embodiment two.
Embodiment
Embodiment one
The solar automatic tracking lighting device of present embodiment as shown in Figure 1, mainly the sun light tracking sensor 3 that transmits detectable signal by the light signal feedback processing circuit (not shown) of optically focused daylighting element 2, the mechanical driving device that drives the motion of optically focused daylighting element, control mechanical driving device, to light signal feedback processing circuit is formed.Wherein, four groups of optically focused daylighting elements 2 are placed in the cylindrical shell 1, and coupling passes light optical fiber 9 near its focus.Sun light tracking sensor 3 is installed in the cylindrical shell top.Main shaft 7 in the mechanical driving device uprightly is installed on the base of mainshaft mechanism in 8, and upper end and U-shaped support 6 are connected.Cylindrical shell 1 both sides are connected auxilliary 4, and are supported on the U-shaped support 6 by auxilliary axle 4, thereby auxilliary axis mechanism is superimposed upon on the mainshaft mechanism.Main shaft can be by the motor-driven of band worm type of reduction gearing.In order to overcome the excessive back lash of worm and gear, the worm screw two ends adopt eccentric bearing holder (housing, cover) to be adjusted.Auxilliary spindle motor 5 is hinged with the motor frame 12 that is fixed on the U-shaped support 6, and its output terminal is connected with screw mandrel 10.The nut 11 that screws with screw mandrel 10 is hinged on the cylindrical shell 1.Like this, assist spindle motor 5 and adjust elevation angles by optically focused daylighting element 2 motions that leading screw and nut mechanism drives in the cylindrical shell 1.
In order to protect optically focused daylighting element 2, cylindrical shell 1 front end can be installed the high transmission rate cover plate; In order to prevent that dust, rainwater etc. from entering in the cylindrical shell 1, cylinder back-end can be installed protective cover.
In the work, when the sunshine incident ray became a misalignment angle with the center line of optically focused daylighting element, the focused light spot of sensor collector lens dropped in a certain quadrant of photovoltaic detector.After light signal feedback processing circuit receives the electric signal of this quadrant output, to drive corresponding motor, and drive an optically focused daylighting element by main shaft or auxilliary axle and rotate towards the direction that reduces this misalignment angle, incident ray until the sun is parallel with the central axis of optically focused daylighting element, converge near the biography light optic fibre input end of its focal spot, pass light optical fiber by this again sunshine is sent to required place.
This mechanism's benefit is: the adjustment of elevation angle is owing to adopted the nut screw body, and drive ratio is more laborsaving, and the motor 5 of auxilliary axis mechanism does not need subsidiary speed reduction unit, solves the drive gap problem of mainshaft mechanism, auxilliary axis mechanism preferably, and cost reduces.
Embodiment two
The solar automatic tracking lighting device of present embodiment as shown in Figure 2, its basic structure is identical with embodiment one, difference is: auxilliary axle 4 directly is connected with motor 5 output terminals of band reduction gear, compare with embodiment one like this, mechanism is slightly simpler, but requires to have improved a lot to the mechanical clearance of motor and reduction gear thereof.
Facts have proved, the solar automatic tracking lighting device compact conformation of above embodiment, stable drive is convenient to installation and maintenance, and mechanical clearance etc. overcome easily, have good practicality.
