Description
Technical field
The present invention relates to a kind of solar tracking system, the in-line double-shaft solar tracking system of especially a plurality of solar energy light collecting plates.
Background technology
Existing solar tracking system generally adopts complex mechanical construction to follow the tracks of the sun, and it is the cost of manufacture height not only, and breaks down easily.Utilize system for solar energy composite, because plane skylight is a lot, and the position that plane skylight is placed is uneven, and each plane skylight is by a plane skylight stent support.Therefore, utilize system for the solar energy composite with a plurality of plane skylights, if be equipped with solar tracking system, each plane skylight support all needs to link to each other with a solar tracking system.This has just increased cost greatly.
Summary of the invention
The purpose of this invention is to provide a kind of double-shaft solar tracking system simple in structure, with low cost.
This double-shaft solar tracking system comprises plane skylight, supports plane skylight support, rotary column, solar tracking device, drive motor, the tracking drive mechanism of plane skylight; The plane skylight support rotates and is arranged on the rotary column, is provided with to be used to drive the elevation angle driving mechanism that the plane skylight support rotates with respect to rotary column between rotary column and plane skylight support; The output of solar tracking device connects drive motor, and drive motor links to each other with the tracking drive mechanism that drives the rotary column rotation, and rotating shaft that rotary column rotates and plane skylight support are perpendicular with respect to the rotating shaft that rotary column rotates.
Beneficial effect of the present invention: the present invention monitors the solar light incident angle in real time with existing solar tracking device, and the rotation of output signal controlling and driving motor, drives rotary column by tracking drive mechanism and rotates; In addition, also rotate with respect to rotary column, like this, just can make that plane skylight faces the sun all the time by elevation angle drive mechanism plane skylight support.Therefore, the present invention is with respect to the solar tracking system of complex mechanical structure, and is simple in structure, easily manufactured, cost is low.
Above-mentioned tracker, tracking drive mechanism comprise that the worm screw that links to each other with drive motor, the worm gear that cooperates with worm screw, rotary column are fixed on the worm-wheel shaft.Described plane skylight is more than 2, and the quantity of rotary column and tracking drive mechanism is all identical with plane skylight; Each plane skylight links to each other with a plane skylight support, and each plane skylight support rotates and is arranged on the rotary column, and each rotary column is fixed on the worm-wheel shaft, links to each other with universal drive shaft between two adjacent worm screws.Owing to be adjacent two worm screws to be linked to each other with universal drive shaft, so can being placed on, each plane skylight support is uneven or not on (45 ° of maximum delivered corners (universal drive shaft and worm screw between maximum angle)) with each position on the straight line, and, can drive each tracking drive mechanism with a drive motor, reduce cost.Worm screw is the ring surface enveloped worm screw of secondary.Adopt worm gear and the ring surface enveloped worm screw of secondary, it is many to engage the number of teeth, and driving torque is big, and running steadily has self-lock ability, can resist the 150m/s typhoon.
Elevation angle driving mechanism can be varied, a kind of simple elevation angle driving mechanism comprises the elevation angle drive motor that is arranged on the rotary column, the elevation angle that links to each other with elevation angle drive motor drives worm gear, the elevation angle that drives worm wheel with the elevation angle drives worm screw, the nut that links to each other with worm screw, nut cooperates with screw mandrel on being arranged on the plane skylight support.

Fig. 1 is a synoptic diagram of the present invention
Embodiment
Referring to tandem double-shaft solar tracking system shown in Figure 1, it comprises 3 plane skylights 1, supports 2,3 tracking drive mechanism 3 of 3 plane skylight supports, solar tracking device 4,7,3 elevation angle driving mechanisms 9 of 5,3 rotary columns of drive motor of plane skylight.Tracking drive mechanism 3 comprises (the ring surface enveloped worm screw of secondary) 31, the worm gear that cooperates with worm screw.Each plane skylight 1 links to each other with a plane skylight support, and each plane skylight support 8 rotations around the shaft is arranged on the rotary column, and each rotary column is fixed on the worm-wheel shaft.
The output of solar tracking device 4 connects servo drive motor (servomotor) 5, worm screw 31 left ends in the tracking drive mechanism 3 in drive motor 5 and left side link to each other, and the left end of the worm screw 31 in the middle tracking drive mechanism 3 links to each other by worm screw 31 right-hand members in the tracking drive mechanism 3 in universal drive shaft (two ends have the transmission shaft of universal joint 61) 6 and left side; The right-hand member of worm screw 31 in the middle tracking drive mechanism 3 links to each other by worm screw 31 left ends in the tracking drive mechanism 3 on universal drive shaft 6 and right side.
Elevation angle driving mechanism 9 comprises the elevation angle drive motor that is arranged on the rotary column, the elevation angle that links to each other with elevation angle drive motor drives worm gear, the elevation angle that drives worm wheel with the elevation angle drives worm screw, the nut that links to each other with worm screw, and nut cooperates with screw mandrel on being arranged on the plane skylight support.Drive motor action in the elevation angle drives the elevation angle and drives worm gear and rotate, and the elevation angle drives worm screw and nut just rotates, because screw mandrel cooperates with nut, screw mandrel just moves axially along nut, 8 rotates with respect to rotary column around the shaft thereby screw mandrel just drives the plane skylight support.
The motion of tracker control servomotor drives rotary column and rotates, and change every day one, make plane skylight follow the tracks of the sun from the east to the west, electronic elevation angle driving mechanism is according to the elevation angle of the variation of sunshine control plane skylight, make its plane skylight all the time with the sunshine vertical irradiation, reach best daylighting effect, rotary column adopts zero stand-off worm and gear transmission, and worm screw is adopted the ring surface enveloped worm screw of secondary, and it is many to engage the number of teeth, driving torque is big, running steadily has self-lock ability, can resist the 150m/s typhoon.Electronic elevation angle transfer bar mechanism adopts the elevation angle to drive worm gear, the elevation angle drives worm screw and drives the nut stretching motion, and self-lock ability is strong.Nut, plane skylight support, rotary column form a triangular structure, Stability Analysis of Structures, and wind loading rating is strong.By the connection of universal drive shaft, utilize a drive motor can drive many tracking drive mechanism, not influenced by topography and geomorphology, 45 ° of maximum delivered corners.The a plurality of tracking drive mechanism of one controller, one motor-driven greatly reduce the cost of tracker.
