Description

Three parallelly connected trackers of a kind of solar energy
Technical field
The present invention relates to a kind of solar tracking device that is used for solar tracking system, especially relate to good, the easy for installation three parallelly connected trackers of solar energy of a kind of wind resistance simple in structure, stable.
Background technology
Solar tracking system is a kind ofly to realize the maximized device of photovoltaic module energy output through the real-time tracking sun.It can keep solar panel at any time over against the sun, and the light that makes sunlight is the power set of vertical irradiation solar panel at any time, can significantly improve the generating efficiency of solar photovoltaic assembly.Because the rotation of the earth; With respect to the solar photovoltaic generation system of some fixed locations, throughout the year, day every day rise sunset, the lighting angle of the sun is at every moment all changing; Guarantee that effectively solar panel can be constantly over against the sun, generating efficiency just can reach optimum state.
Solar tracking device is one of critical component in the solar tracking system.At present, common solar tracking device all is a twin shaft tandem drive mechanism, generally comprises single support column; The photovoltaic panel assembly support is connected on the support column, and this support column can be rotated around self axis, and the photovoltaic panel support can swing up and down on support column; Thereby realize the variation to photovoltaic panel support Plane Angle, but this solar tracking device being the angle on the horizontal plane at need of work elder generation adjustment support column, is the angle on the vertical plane at adjustment photovoltaic panel support then; Reach final regulating effect through twice adjusting, this implementation of solar tracking device as a result is slower, and structure is more complicated also; Processing cost is high, and installation effectiveness is low, and maintenance cost is also high; And executive component is wide in variety, is out of order easily.Single-column supports in addition, and structural stability is poor, and wind resistance is relatively poor.Like Granted publication number is CN201965490U; Name is called a kind of solar tracking device that is used for solar tracking system; It comprises column and support arm, is provided with floating bearing between column and the support arm, and support arm can horizontally rotate on column through floating bearing; Hinged through hinged seat and photovoltaic module fixed mount on the support arm, this photovoltaic module can swing up and down on support arm.This sun grace can tracker be twin shaft tandem drive mechanism just, and just have above-mentioned shortcoming: implementation is slower, and structure is more complicated also, and processing cost is high, and installation effectiveness is low, and maintenance cost is also high, and executive component is wide in variety, is out of order easily.Single-column supports in addition, and structural stability is poor, and wind resistance is relatively poor.
Summary of the invention
The present invention mainly is that solar tracking device is a twin shaft tandem drive structure in the solution prior art; Complex structure, the processing maintenance cost is high, installation effectiveness is low, be out of order easily; And structural stability is poor; The technical problem of wind resistance difference, provide a kind of simple in structure, the processing maintenance cost is low, fault is few, easy to control, good stability and the high three parallelly connected trackers of solar energy of windproof performance.
Above-mentioned technical problem of the present invention mainly is able to solve through following technical proposals: three parallelly connected trackers of a kind of solar energy; Comprise the photovoltaic module fixed mount and be fixed on the photovoltaic module on the photovoltaic module fixed mount; Tracker includes three pull bars that can stretch automatically; Said pull bar is in triangular distribution, and the pull bar upper end is connected photovoltaic module fixed mount bottom through universal joint, and the pull bar lower end is connected on the mount pad.The present invention adopts the mode of three pull bars to realize the tracking to the sun; The photovoltaic module fixed mount is installed on three pull bars; The upper end of three pull bars forms at 3 and confirms a plane; The angle that has just realized this plane through the different collapsing lengths of regulating pull bar changes, and has realized that promptly the angle of photovoltaic module changes, and photovoltaic module can face toward the sun all the time when making daytime.The present invention adopts the support of three pull bars as photovoltaic module, compares with traditional biaxial tracker, and its structure is more simple, and stability, wind resistance is better, installs more convenient.The present invention is when changing photovoltaic module, and three pull bars stretch simultaneously, and it is fast to regulate the speed, and these three pull bars are same performance element, during use fault still less, more easy to control.The present invention adopts three pull bars to realize that not only the angle on photovoltaic module plane changes, and can also realize the photovoltaic module height change, to satisfy the needs of different installation environments.Pull bar is electronic pull bar, on the pull bar lower end, is provided with motor, is used for pull bar is carried out push-and-pull.
As a kind of preferred version, the setting that slopes inwardly of said pull bar, the triangle area of 3 formations in pull bar upper end is less than the triangle area of 3 formations in pull bar lower end.Pull bar is recessed, and three pull bars form the mechanism of similar terrace with edge, and this makes that photovoltaic module fixed mount, the photovoltaic module installed on pull bar are more steady, and wind resistance is better.
As a kind of preferred version, the pull bar lower end is hinged on the mount pad through hinged seat, hinged seat comprise pedestal be rotatably connected on the articulated joint on the pedestal, said pedestal is fixed on the mount pad, articulated joint and pull bar lower end fix.Pull bar is hinged on the mount pad; This pull bar can be swung; Change the link position of pull bar upper end on the photovoltaic panel fixed mount; Photovoltaic fixed mount appearance not of uniform size be like this, can regulate the angle between pull bar and the ground, make the photovoltaic fixed mount that is connected the pull bar upper end install more steady according to the shape flexible in size of photovoltaic fixed mount.
As a kind of preferred version; Said photovoltaic panel fixed mount comprises some main brace summers and time brace summer, parallels setting between said main brace summer, and inferior brace summer is laid on the main brace summer; Inferior brace summer and main brace summer are perpendicular; Constitute the square grid shape structure, said photovoltaic module is fixed on time brace summer, and said universal joint is fixed on the main brace summer.Main brace summer is used to support photovoltaic module and transmits the thrust of pull bar, and inferior brace summer is used for fixing and supports photovoltaic module.Photovoltaic module is fixed on twice brace summers, and inferior brace summer is one group of setting with twice brace summers when laying.
As a kind of preferred version, said main brace summer is the square hollow bar, and said brace summer is the door font, and the both sides outward flanging of inferior brace summer forms and connects the edge.Main brace summer can adopt square hollow profile, and the connection that this time brace summer forms is continued to use in welding mutually with main brace summer.
As a kind of preferred version, be connected with buttress brace between the said adjacent main brace summer, buttress brace becomes the polyline shaped setting.Buttress brace makes that the photovoltaic module fixed mount is more firm.
Therefore, tool advantage of the present invention is: 1. adopt three-axis parallel to drive, implementation is faster, and structure is simpler, and installation effectiveness is high, and the processing maintenance cost is lower; 2. three posts support, and structural stability is better, and wind resistance is high; 3. executive component is single, and fault is few, and is easy to control.
