Description
Technical field
The utility model relates to a kind of photovoltaic power generation apparatus, relates in particular to the photovoltaic power generation apparatus with following function.
Background technology
Photovoltaic generation is to utilize the photovoltaic effect of interface and a kind of technology of luminous energy directly being changed into electric energy.The key element of this technology is solar cell.Solar cell by some forms solar module after connection encapsulation, then coordinates the parts such as upper power controller just to form photovoltaic power generation apparatus.
In order to make photovoltaic power generation apparatus obtain maximum power output, must be in conjunction with geography, weather and the solar energy resources condition in construction place, by solar module with certain towards installing, to guarantee that solar cell obtains maximum illumination resources.Theoretically, if solar cell can be constantly over against the sun, its generating efficiency will reach optimum state.
Solar module is mounted on the support of photovoltaic power generation apparatus, and so, the needed installation of solar cell is towards namely being guaranteed by the support of photovoltaic power generation apparatus.The supporting structure pattern of most photovoltaic power generation apparatus is fixed installation pattern, after installing with the support of this pattern, the installation of photovoltaic cell component is towards also just having decided, also in use changeless, certainly, it is installed towards being definite afterwards as calculated according to the longitude and latitude on photovoltaic power generation apparatus installation ground, can guarantee that photovoltaic power generation apparatus has relatively high efficiency.Such supporting structure is simple, convenient for installation and maintenance, but obviously its generating efficiency is can be very not high.
In order to improve the generating efficiency of photovoltaic power generation apparatus, people have developed the photovoltaic power generation apparatus with solar tracking automatic control system, this class solar tracking control system has two kinds of patterns substantially, a kind of is single-shaft tracking system, it can follow the tracks of the azimuth of the sun, or follow the tracks of the elevation angle of the sun, make the solar cell in one direction can be over against the sun, thereby improved the generating efficiency of device of solar generating; Another kind is dual-axis tracking system, and it not only can follow the tracks of the azimuth of the sun, can also follow the tracks of the elevation angle of the sun simultaneously, can follow the tracks of the running orbit of the sun completely in theory, thereby makes solar cell constantly over against the sun, reach best generating effect.The solar tracking automatic control system of this class is generally to be driven by mechanisms such as worm and gears by servomotor, thereby makes solar module and installation frame thereof rotate and realize the function of following the tracks of around corresponding axle.
With regard to the above-mentioned two kinds photovoltaic power generation apparatus with solar tracking automatic control system, dual-axis tracking system is because mechanism is complicated, cost is high, the low and less application actually of reliability, what application was more more conventionally is single-shaft tracking system, and is mainly the elevation angle of following the tracks of the sun.
Even if adopt the photovoltaic power generation apparatus with sun altitude tracking automatic control system, the initial stage drops into still to be increased much, and working service cost and workload be corresponding increase also.Also has further problem, due to the needs of following the tracks of, need solar module to change its angular pose according to the position of the sun, whole solar module and installing rack thereof are in active state, moving component and fixed part junction certainly exist certain gap, like this, the structural rigidity of whole device is just poor, and whole device can only be to lean on the auto-lock function of worm and gear to come holding position, conventionally photovoltaic power generation apparatus is always mounted in field, sun-drenched wilderness, as deserted mountain, Gobi desert, the ground such as seashore beach, these local normal wind are all very strong, past contact is with sand and dust, under strong wind action, large-area solar module can be received larger active force, structural rigidity own is caused to damage with regard to the poor photovoltaic power generation apparatus with solar tracking control system, and transmission mechanism also can very easily damage under the effect of sand and dust, cause the transmission devices such as worm and gear to work, self-locking property weakens, following the tracks of regulatory function also just cannot realize, at this moment solar module is partial to a certain extreme position under the effect at wind-force towards meeting, and can be stuck in this position, obviously this position can not be the service position of a comparatively desirable solar cell, there is such situation, affected on the contrary the generating efficiency of photovoltaic power generation apparatus.
Utility model content
