A kind of photovoltaic power generation apparatus following the trail of the sun
A kind of photovoltaic power generation apparatus following the trail of the sun of the utility model
,what relate to is device of solar generating technical field, is applied to photovoltaic battery panel and follows the trail of sun generating.
At present, the transmission of solar condensing power generation device both domestic and external and tracking, the problem of solution is application photovoltaic cell of the same area, makes full use of luminous energy, reaches best generating state.Analyze from the transmission of domestic solar condensing power generation device and the situation of tracing system, domestic photovoltaic battery panel follows the trail of the optical component sensitivity used of the tracing system of sunlight and service precision reaches international most advanced level, the operation of direct tracking is relatively reliable, and the precision of tracking is high.But, because the stability of the transmission mechanism of solar condensing power generation device is relatively poor, counteract part efficiency, add the energy loss of solar condensing power generation device.With regard to its main cause, existing transmission mechanism, general employing one root post support solar concentrating generation device, except the weight of itself directly affects except stability, due to the impact of by wind and wind speed, especially easily produce and rock, constrain the area of photovoltaic battery panel.So, the photovoltaic battery panel area of existing solar condensing power generation device is unsuitable excessive, the power of the solar condensing power generation device formed is relatively little, except transmission and tracing system electricity consumption, the power output of solar condensing power generation device is not very high, wastes the cost of investment of transmission and tracing system.
Summary of the invention
The purpose of this utility model overcomes above-mentioned defect, design a kind of large-area photovoltaic battery panel, overcome wind-force and wind speed to the impact of large-area photovoltaic battery panel, adopt Dual-spindle linked, make sunlight direct projection photovoltaic battery panel, form a kind of photovoltaic power generation apparatus following the trail of the sun that the power of Blast Furnace Top Gas Recovery Turbine Unit (TRT) is relatively high.
Its technology is achieved in that and comprises rotating shaft, hinge, photovoltaic battery panel, framework, bearing, screw mandrel, swivel nut, servomotor, column, it is characterized in that: whole device is located in the rotating shaft of being supported by shaft support, the lower end of framework is connected with rotating shaft by hinge, framework lower end be fixed with bearing, bearing is connected with one end of screw mandrel is active, column lower end is fixed in rotating shaft, column is fixed with servomotor, the axle of servomotor is provided with swivel nut, swivel nut is connected by screw thread and screw mandrel are active, framework is fixed with photovoltaic battery panel, the tracing system controlled by industrial computer is provided with in whole device.
Implement the obvious advantage after this technology and effect is: compared with prior art, photovoltaic battery panel vertical plane is to sunlight, and along with sun's motion, the tracing system that industrial computer controls, the motion of instruction transmission device, according to the track of solar motion, forms photovoltaic battery panel vertical plane to the compound motion of sunlight, make full use of luminous energy, make the generating state that photovoltaic battery panel reaches best.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model:
Wherein, 1-drive sprocket, 2-rotating shaft, 3-hinge, 4-photovoltaic battery panel, 5-framework, 6-bearing, 7-screw mandrel, 8-swivel nut, 9-servomotor, 10-column, 11-shaft support.
First, below in conjunction with accompanying drawing, the utility model will be further described:
See accompanying drawing 1, whole device is located in the rotating shaft 2 of being supported by shaft support 11, one end of rotating shaft 2 is fixed with drive sprocket 1, drive sprocket 1 connects motor by chain, the lower end of framework 5 is connected with rotating shaft 2 by hinge 3, the lower end of framework 5 is fixed with bearing 6, bearing 6 is connected with one end of screw mandrel 7 is active, column 10 lower end is fixed in rotating shaft 2, column 10 is fixed with servomotor 9, the axle of servomotor 9 is provided with swivel nut 8, swivel nut 8 is connected with screw mandrel 7 is active by screw thread, framework 5 is fixed with photovoltaic battery panel 4, the tracing system that industrial computer controls is provided with in whole device.
See accompanying drawing 1, first, drive sprocket 1 is rotated by motor and chain-driving rotating shaft 2, and tracing system follows the tracks of sunlight makes photovoltaic battery panel 4 tentatively aim at sunlight.All the time the control of industrial computer is in.Start servomotor 9 to move in the direction of the clock an angle with swivel nut 8, drive the rectilinear motion that screw mandrel 7 upwards pushes up, screw mandrel 7 pushes up, drive framework 5 centered by hinge 3 upwards, photovoltaic battery panel 4 is increased with the angle of rotating shaft 2, until make photovoltaic battery panel 4 by rotating shaft 2, the motion vertical of servomotor 9 is in sunlight, photovoltaic battery panel 4 is made to obtain best generating effect, along with rotating shaft 2 is under tracing system controls, along earth movements direction, position in opposite directions rotates, servomotor 9 drives screw mandrel 7 to do all the time, lower movement, due to both compound motions, photovoltaic battery panel 4 is made to aim at the sun all the time, and it is vertical with sunlight, photovoltaic battery panel 4 is made to obtain maximum generated output.
