A kind of adjustable single shaft photovoltaic bracket manually
The utility model is related to a kind of solar photovoltaic bracket, more particularly, to a kind of adjustable single shaft photovoltaic branch manually
Solar energy is a kind of energy of cleanliness without any pollution, develop when will not produce waste residue, waste water, waste gas, will not
The influence ecological balance, is widely used at present.But solar energy has low, intermittent density, direction of illumination and intensity not
It is disconnected the problems such as change over time.Traditional solar panel mostly uses fixedly mounted, i.e., cell panel is fixed on certain angle
Degree, does not change with the change in location of the sun, and this mounting means has a strong impact on the generating efficiency of photovoltaic plant.To improve the sun
The utilization ratio of energy, increases generated energy, reduces the operation cost of solar power generation, has two kinds of supports of single shaft and twin shaft to track at present
System.Tracking system by cell panel support system, rotating shaft beam, power-driven system, electric control system, central monitoring system etc.
Composition.Its tracking effect of double-shaft auto-tracking system is good, can improve generated energy, it is adaptable to relatively large solar power system
In, but its is low into height, and poor reliability, cost performance is low.Single shaft automatic tracking system structure is quite comparatively simple, appropriate litigation fees compared with
It is low.Current single-shaft tracking system mainly includes mechanical part and control section, and mechanical device is driven by motor, and control section is main
It is made up of SCM system, the electric power signal of photovoltaic module conversion sends into single-chip microcomputer by conversion equipment, is made too by motor
Positive energy cell panel is rotated towards the direction vertical with the sun, and due to there is substantial amounts of information transfer and machine driving, its operation is steady
Qualitative difference.The spring, summer, autumn and winter sun falls from the east of west throughout the year, and light is adjusted with the change in season or the change of light angle
The setting angle of component is lied prostrate, to improve photovoltaic power station power generation efficiency, to be a kind of feasible technical method.Solar bracket system
Largely it is used in solar photovoltaic power plant as the support and fixed component of photovoltaic module, wherein, manual adjustable inclination angle photovoltaic
Fixed support as a kind of new photovoltaic fixed support tentatively start application, be on the basis of fixed angle support, with
The change at sun season angle, is impinged perpendicularly on photovoltaic module to increase by adjusting bracket north and south fixed angle (season angle)
Amount of radiation, so as to increase built photovoltaic power station power generation amount.Common manual adjustable inclination angle photovoltaic fixed support be by horizontal single shaft with
Track support makes into, and it has the disadvantage：As horizontal uniaxial tracking bracket, complex structure, particularly mechanical rotating mechanism, by very
Multi-gear and a parameter case composition for big gear ratio, high cost, processing and installation difficulty.
Chinese patent CN203260598U discloses a kind of solar photovoltaic bracket that can conveniently adjust height and position,
Including photovoltaic panel body, it is characterised in that be connected with support frame on the photovoltaic panel body, be connected with support frame as described above
Support feet and adjustable plate, the support feet are provided with buckle, and the adjustable plate is provided with the draw-in groove that several are adapted with buckle.
This patent is integrally placed adjustable support on one installing plate, and the required precision to installing plate is very high, and difficulty of construction is big；And peace
Dress plate can not possibly be made thin big, not so be difficult rotate, can so cause an adjustable support unit can mounting assembly quantity very
It is limited.Support feet in the patent is movable, does not have (also cannot) to be formed with installing plate and reliably is fixedly connected, entirely adjustable
Support tensile capacity is not all right.Support is integrally placed in two chutes, does not have fixing point, front and rear can be moved after adjustable support wind-engaging
Dynamic, stability is poor, during long-term use, foreign matter can be fallen into chute, influences the smoothness of regulation, it is serious in the case of it is possible
Cannot be adjusted.The support neither one adjusts rotational support equalization point, and adjustable support adjusts highly difficult, may be without legal person
Work is adjusted.
