Description

The main shaft connection structure of solar energy uniaxiality tracking device
Technical field
The utility model relates to a kind of structure of solar energy uniaxiality tracking device, relates in particular to the syndeton between a kind of each main shaft of tracker.
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 present solar energy is all generally in more smooth place with the installation of device, in relatively steeper or piling precision not high lower time of situation for physical features, the installation between each main shaft is just very restricted.
Utility model content
The utility model provides a kind of physical features that can be applicable to have fluctuating, low to the axiality requirement of main shaft, the main shaft connection structure of the convenient solar energy uniaxiality tracking device connecting; The main shaft connection structure that has solved the solar energy uniaxiality tracking device existing in prior art is huge, high to the axiality requirement of main shaft, can only be arranged on the technical problem in smooth relief.
It is a kind of less demanding for verticality of stand column that the utility model also provides simultaneously, and system is installed the main shaft connection structure of stable solar energy uniaxiality tracking device; Solved in the solar energy uniaxiality tracking device existing in prior art high for the installation requirement of column, the technical problem that system is stable not.
Above-mentioned technical problem of the present utility model solves by following technical proposals: a kind of main shaft connection structure of solar energy uniaxiality tracking device, comprise column and main shaft, described column comprises cylinder and is positioned at the supporting seat on cylinder, two main shafts are connected by universal joint on supporting seat, and main shaft is fixed on supporting seat by spindle fixed structure.On column, support the connection of two main shafts by supporting seat, original syndeton has been abandoned in the connection of two main shafts, is connected and is adjusted, due to the use of universal joint by universal joint, if two main shafts can axiality be differed greatly in the time interconnecting, also can realize connection.While is for the position of mountain shape steeper, because the connection of universal joint can make out of line two main shafts can realize connection, realize and also can arrange multiple assemblies in mountain region, form photovoltaic module unit, improve the conversion efficiency of solar energy, also reduced the installation requirement of main shaft and column.
As preferably, described spindle fixed structure comprises main shaft Connection Block and main shaft support seat, main shaft support seat is bolted in the adjustment hole on supporting seat, and the adjustment direction of adjustment hole is vertical with the closure of main shaft, in main shaft Connection Block, is fixed with main shaft by bearing.Regulating block on supporting seat is waist hole, in the time that the perpendicularity of each column in same photovoltaic module unit differs greatly, and the unstable situation with not installing of system that main shaft Connection Block can effectively avoid verticality of stand column to bring by the connection in waist hole.
As preferably, main shaft Connection Block and main shaft support seat are one-body molded, and described bearing is Split plastic bearing, and described main shaft is square shaft.Split type bearing is easy for installation, is convenient to better, save capital.
As preferably, described universal joint is candan universal joint.Simple in structure, the performance of transmitting power is good, and interlock performance is good.
Therefore, the main shaft connection structure of solar energy uniaxiality tracking device of the present utility model possesses following advantage: (1) is applicable to the main shaft installation of the steeper solar tracking device of north and south physical features, and the not high situation of piling precision, can increase single component count simultaneously; (2) when two main shaft axialities differ greatly, candan universal joint can regulate the maintenance of two main shafts and synchronously rotate; (3) when verticality of stand column differs greatly, main shaft Connection Block passes through waist hole, the unstable situation with not installing of system that can avoid verticality of stand column to bring.
