The above-mentioned technical matters of the utility model mainly is able to solve through following technical proposals: three parallelly connected trackers of a kind of sun power; 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 utility model 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 utility model 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 are better, install more convenient.The utility model 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 utility model 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, the utility model tool advantage 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.
