Concentrating solar generating tracking rotary table

Technical field

The present invention relates to a kind of rotating driving device, relate in particular to concentrating solar generating tracking rotary table.

Background technology

Along with the social progress people constantly increase the demand of the energy, seek the new and renewable sources of energy problem that become international, sun power is considerable as a kind of development prospect in cleanliness without any pollution, the regenerative resource.Present stage solar electrical energy generation most what adopt is the silicon wafer cell panel, fixed installation, its conversion efficiency is not high, probably about 15%.Progress along with science and technology, domestic many universities and colleges and enterprise use the higher light-focusing type gallium arsenide cell panel of generating efficiency in research at present, instant sun-tracing light, light-focusing type gallium arsenide cell panel photoelectric transformation efficiency can reach 40%～50%, reach accurate optically focused, stable solar tracking device is essential.

Summary of the invention

For satisfying the requirement of concentrating solar generating accurate tracking, the invention provides that a kind of cost is low, good stability, self power consumption is little, moment of torsion is big, the simple concentrating solar generating of technology tracking rotary table.

Concentrating solar generating tracking rotary table comprises fixed part and rotating part; Fixed part is by a chassis with U-shaped gathering sill, a reducing motor that is fixed on the chassis, two worm reduction boxs that are symmetrically fixed on the chassis, reducing motor is connected with two worm reduction box main drive shafts on the chassis respectively by coupling shaft, uniformly more than three be fixed in the outer double-screw bolt of the U-shaped gathering sill in chassis and be assemblied in pressing plate on the double-screw bolt, pressing plate is loaded onto by the little ball more than two and is formed, and rotating part is made up of with the gear ring of U-shaped gathering sill, the steel ball that rolls in the U-shaped gathering sill of gear ring more than three and two driving gears a bottom.Two driving gears are connected with two output shafts that are symmetrically fixed on the worm reduction box on the chassis, two transmission shafts about reducing motor passes through, thereby drive two worm reduction box main drive shafts and make the driving gear rotation that is assemblied on the worm reduction box output shaft, driving gear and the engagement of gear ring internal tooth symmetry drive gear ring and rotate, thereby make the top rotary table rotation that is fixed on one with gear ring, the left and right rotation angles of top rotary table is spacing by being fixed in link stopper and the limit switch control of being fixed on the chassis on the gear ring.

Have U-shaped gathering sill on the chassis of described fixed part, outside being with U-shaped gathering sill, be evenly equipped with three with upper stud, pressing plate is housed on the double-screw bolt, and pressing plate is loaded onto the little ball more than two, and further characteristics are reducing motor and two worm reduction boxs composition dual drive systems on the base.

The top rotary table of described rotating part is connected with gear ring, is processed with internal tooth on the gear ring inner ring, and U-shaped gathering sill is with in the bottom, is made up of driving gear, link stopper, limit switch, and further characteristics are to be placed with three above balls at least in the U-shaped gathering sill in gear ring bottom.

Beneficial effect of the present invention is:

The one, rotating part adopts and to be processed with internal tooth on the gear ring inner ring and to pay as transmission, and globality, rigidity are good, have saved intermediate member, thereby have reduced processing cost.

The 2nd, rotating part drives the worm reduction box that adopts reducing motor to drive two symmetrical distributions with speed, two driving gear symmetries on the worm reduction box output shaft drive gear ring and rotate, moment equilibrium, running steadily, form certain arm of force with rotation center, bigger than axis driving torque, and institute's wasted work rate is little, and self-locking property is good, can not influence tracking accuracy because of wind-force.Solar tracking system requires the slow-speed of revolution, and along with the big arm of force of fluted disc increasing diameter is also elongated thereupon, the fluted disc rotating speed slows down, but moment will be multiplied under same driving force effect.

The 3rd, rotating part adopts the gear ring bottom to have U-shaped gathering sill and places ball, and the ball bottom places in the chassis with U-shaped gathering sill, and friction force is little, and bearing capacity is big, and can limit the rotating part radial displacement.

The 4th, fixed part adopts and fix three with upper stud outside the U-shaped gathering sill in chassis, and pressing plate is housed on the double-screw bolt, thereby little ball and the gear ring outside flange edge joint placed under the pressing plate more than two touch control gear ring end play.

Embodiment

Below in conjunction with accompanying drawing, the present invention is done detailed explanation, shown in Fig. 1, Fig. 2 synoptic diagram, when being the generating of concentrating solar plate, follows the tracks of concentrating solar generating tracking rotary table the drive unit of sunshine.Be with U-shaped gathering sill on the concentrating solar generating tracking rotary table base 1, the worm reduction box 3 of 5 two symmetries of a reducing motor is equipped with in base 1 bottom, the main drive shaft of two worm reduction boxs 3 is connected respectively with reducing motor 5 left and right sides shafts by coupling shaft 6, on worm speed-down case 3 output shafts driving gear 4 is housed, driving gear 4 and the engagement of gear ring 12 internal tooths symmetry, gear ring 12 is fixed on one with top rotary table 8, gear ring 12 is by ball 2 load-bearing in the U-shaped gathering sill in bottom and the base 1U type gathering sill and limited moving radially of gear ring, U-shaped gathering sill fixedly has three with upper stud 11 outward on the base 1, pressing plate 9 is housed on the double-screw bolt 11, pressing plate 9 bottoms are placed with little ball 10 more than two, the last little ball 10 of pressing plate 9 contacts with gear ring 12 flanges, thereby the axial runout of control gear ring 12 fixedly has link stopper 14 and is fixed on two limit switches 13 on the base 1 and controls the angle of gear rings 12 and top rotary table 8 left rotation and right rotation on the gear ring 12.Reducing motor 5 is connected with worm reduction box 3 main drive shafts by coupling shaft 6, drive driving gear 4 and the symmetrical engagement of gear ring 12 annular wheels through worm reduction box 3 deceleration output backs, drive gear ring 12 and be attached thereto all-in-one-piece top rotary table 8 and rotate, link stopper 14 fixing on gear ring 12 flanges cooperates with two limit switches 13, the angle of control gear ring 12 left rotation and right rotation, angle control keeps sealing state for making the rotating disk rotating part within 200 degree, top rotary table 8 outsides have installed O-ring seal 7 additional.

Because reducing motor 5 is the worm reduction box 3 of two symmetrical distributions of speed driving together, the driving gear 4 on worm reduction box 3 output shafts meshes with gear ring 12 internal tooths symmetry, so running speed is steady, and moment equilibrium.Because forming certain arm of force with rotation center, self institute's wasted work rate is little.The concentrating solar tracker requires the slow-speed of revolution, and along with the big arm of force of gear ring 12 increasing diameters is also elongated thereupon, gear ring 12 rotating speeds slow down, and driving moment will be multiplied under the constant situation of institute's wasted work rate, can drive more large-area concentrating solar cell panel.

Embodiment only is optimum implementation of the present invention in sum, as protection scope of the present invention is limited, to the adjustment that does not exceed technical solution of the present invention and the change that the present invention has done, should not think in protection scope of the present invention.
