Technical field
The utility model relates to a kind of structure of photovoltaic tracking device, relates in particular to the syndeton between a kind of each main shaft of photovoltaic tracking device.
Background technology
Tapping a new source of energy with renewable and clean energy resource is the common issue that the whole world faces.In new forms of energy, photovoltaic generation attracts tremendous attention.But due to too high cost, also fail at present fully to come into the market.Photovoltaic generation market prospects are wide, but solar energy utilization ratio is low, is faced with construction cost high, the problem that rate of return on investment is low.The assembly installation form of photovoltaic generation mainly contains the modes such as fixed angle formula, uniaxiality tracking, double-axis tracking.
It is that assembly fixes on the ground with certain inclination angle that fixed angle formula is installed, and whole power generation process assembly is in static state, and this mounting means is simple, and cost is low.But the sun is in dynamic movement process, and in one day, sunlight and solar panel relative position moment are all changing, and light vertical time relative to cell panel is very short.Research shows, solar panel generating capacity is directly proportional to receiving vertical light intensity, has more than 35% energy every day by invisible slatterning.In addition, in order to prevent that the bad weather such as strong wind, heavy snow from may damage the support of solar panel, that generally the coefficient of safety of basis and support is designed is very high.
In order to overcome the problems referred to above, improve the utilization ratio of solar energy, increase energy output, reduce the operation cost of solar power generation, control the photovoltaic generation mode of battery panel components rotation, i.e. single shaft and dual-axis tracking system.Wherein single shaft refers to that battery panel components only has a rotary freedom, (east-west direction) upper sun of following the tracks of at azimuth, and dual-axis tracking system refers to the mode of following the tracks of solar motion in solar azimuth and elevation angle simultaneously.
No matter be that tracking mode, the main axle structure of the drive photovoltaic module rotation of solar tracking device is all very important.
Chinese patent: " pivot structure that solar tracking system is used and solar tracking system (CN201369689Y) ", it drives worm type of reduction gearing by stepping motor, drive respectively upper and lower two rotating shaft synchronous rotaries, drive whole solar panels to rotate by the upper lower chuck of mounting bracket again, the pivot structure that whole solar tracking system is used is installed on the existing column of airfield equipment, without other column by the installation anchor ear being fixed on rotating shaft step.
But the rotating shaft of present solar tracking device is all generally square tube, connection between the rotating shaft of square tube still connects by the connecting axle of square tube, the structure of square tube connecting axle is excessive, be arranged on complex structure on column, need to special bearing pedestal mount pad be set outward at column, then bearing and square tube connecting axle are installed, thereby are made the mounting structure complexity of column, inefficiency.
Utility model content
It is little that the utility model provides a kind of structure to simplify volume, conveniently installs, location and adjusting, and can realize the main shaft connection structure of the photovoltaic tracking device of the pre-installation of column; The main shaft connection structure that has solved the photovoltaic tracking device existing in prior art is huge, and the technical problem that column is wasted time and energy is installed.
Above-mentioned technical problem of the present utility model solves by following technical proposals: a kind of main shaft connection structure of photovoltaic tracking device, comprise main shaft and connecting axle, connecting axle is arranged on column, main shaft is arranged between two adjacent upright posts, connecting axle is pipe, and main shaft is square tube, is provided with main shaft connector in the end of main shaft, main shaft connector comprises location structure and fixed structure, is provided with the fixed structure corresponding with main shaft connector on connecting axle.Connecting axle is pipe, and volume is little, and the cross section of connecting axle is less than column, main shaft first can be arranged on column, then pillar construction good pre-installation is carried out to scene and installs.The structure of main shaft is constant, and main shaft is connected by the main shaft connector of spindle nose with connecting axle, by the location structure of main shaft connector, main shaft and connecting axle is located, and then by fixed structure, main shaft is connected with connecting axle.
As preferably, weld by main shaft capping the end of described main shaft connector, described fixed structure comprises two fixed heads that are parallel to each other, two fixed heads are welded in the main shaft capping of end of main shaft, on fixed head, offer fixing hole, fixing hole is mounting hole, and the distance between two fixed heads is not less than the diameter of connecting axle, on connecting axle, offer the through hole corresponding with fixing hole, in fixing hole and through hole, cross-under has bolt.Distance between the diameter of connecting axle and two fixed heads is roughly equal, and the similar U-shaped draw-in groove of fixed structure, simultaneously by fixed head is set, conveniently utilizes bolt to cross main shaft by fixing hole cross-under and connecting axle interfixes both.On fixed head, offer mounting hole, can facilitate and carry out in the axial direction the fixing adjustment in position.
As preferably, the through hole on fixing hole and connecting axle on described main shaft is two, and fixing hole arranges along the axial direction of main shaft, and through hole is arranged along the axial direction of connecting axle.Two through holes can increase fixing firmness, also can increase the amplitude of adjusting.The length of two mounting holes can be inconsistent.
As preferably, the detent mechanism on described main shaft connector is a baffle plate, and baffle plate is between two of fixed structure parallel fixed heads, and the two ends of baffle plate are welded on respectively on the fixed head at two ends.Because the volume phase countershaft of main shaft is larger, in order to facilitate both location, when main shaft is installed, be that main shaft is sling and placed from the top down, baffle plate is overlapped in rotating shaft, by both location positionings, and then utilizes fixed structure that both are fixedly connected with.
As preferably, the cross section of described column is " H " shape, and column comprises the column wing plate of column listrium and column listrium both sides, on column listrium, offers through hole, and bearing pedestal is plugged in through hole, is provided with bearing in bearing pedestal, and connecting axle is plugged in bearing.On column, offer through hole bearing and connecting axle are installed, can be after the good pillar construction of pre-installation thereby realize, then pillar construction is installed in the tracking system of whole photovoltaic module, can the direct application of force of column structure install, simple in structure, it is convenient time saving and energy saving to install.
Therefore, the main shaft connection structure of a kind of photovoltaic tracking device of the present utility model possesses following advantage: compact conformation, and volume is little, and on-the-spot fitting operation is convenient, and adjusting function is good.
