Stressedly act on turntable bearing uniformly by the lifter pedestal and cover for what make lifter, further, described lifter pedestal is " " shape, is connected by crossbeam between top and the support column.
Stressed evenly further, described support column has two at least, is " ▽ " shape in order to make, and connects by drag-line between about the top.
In order to make elevation angle flip-flop movement steady, further, be connected by air spring between described cell panel platform and the support column.
Compared with prior art, usefulness of the present utility model is: this large-sized photovoltaic is incorporated into the power networks that the double-axis tracking system architecture is simple, physical strength good, reliable, easy for installation, supervisory system is applied widely, solar irradiation can the utilization ratio height, be a complete novel electromechanical system scheme from the tracker to the remote monitoring, have fine photovoltaic industry application prospect.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the utility model large-sized photovoltaic double-axis tracking system architecture synoptic diagram that is incorporated into the power networks.
Among the figure: 1, cell panel platform; 2, lifter; 3, drag-line; 4, support column; 5, air spring; 6, crossbeam; 7, lifter pedestal; 8, turntable bearing lid; 9, turntable bearing; 10, planetary reducer.
Embodiment:
Below in conjunction with the drawings and the specific embodiments the utility model is described in detail:
A kind of large-sized photovoltaic shown in Figure 1 double-axis tracking system that is incorporated into the power networks, comprise cell panel platform 1, described cell panel platform 1 below is provided with support column 4, support column 4 bottoms are connected with the turntable bearing lid 8 that arranges thereunder, described support column 4 has two at least, be " ▽ " shape, connect by drag-line 3 between about the top, make stressed evenly; Also be provided with for the lifter pedestal 7 that lifter 2 is installed on the described turntable bearing lid 8, described lifter pedestal 7 is " " shape, be connected by crossbeam 6 between top and the support column 4, the stressed of lifter 2 acted on the turntable bearing lid 8 uniformly by lifter pedestal 7; This lifter pedestal 7 is between support column 4, and described turntable bearing covers 8 belows and is provided with turntable bearing 9, and this turntable bearing 9 drives by the planetary reducer 10 that arranges thereunder; In order to make elevation angle flip-flop movement steady, be connected by air spring 5 between described cell panel platform 1 and the support column 4.
Its concrete working method is as follows, planetary reducer 10 moves by internal gear behind planetary gear speed-reduction again, the turntable bearing lid 8 that promotion is supported on the turntable bearing 9 rotates, and the support column 4 that cell panel platform 1 is installed is fixed on the turntable bearing lid 8, the rotation of turntable bearing lid 8 drives cell panel platform 1 in the tracking of east-west direction, adopts PLC to control its position angle; The tracking aspect at the elevation angle, lifter 2 adopts the motor-driven linear actuator to move to realize the tracking of cell panel platform 1 on North and South direction, its motion control adopts the inductance type proximity transducer to follow the tracks of angle as the feedback of performance element to control it, adopts high precision dip sensor, the accurate membrane potential device of individual pen and current sensor to detect its actual running status simultaneously; Connect cell panel platform 1 and support column 4 by air spring 5, make elevation angle flip-flop movement steady.
This large-sized photovoltaic double-axis tracking that is incorporated into the power networks is that physical construction is simple novel, intensity is high, can bear very big dynamic loading, can adapt to complicated harsh outdoor environment for use.Its elementary structure parameter is: the assembly erection space is 90m 2, it is ± 120 ° that angular range is followed the tracks of at the position angle, and it is 0~60 ° that angular range is followed the tracks of at the elevation angle, and can bear maximum wind velocity is 175km/h, and the separate unit peak power is 13kw.
