Embodiment
Terminological interpretation:
" blind end " of guide rail alleged by the present invention, from in the narrow sense, refer to that one end of guide rail is for closing (this blocks in this end by guide rail) structure, so that as the last fulcrum of many row's photovoltaic brackets, from broadly understanding, " blind end " refers to this end and is relative fixed enclosed construction (as traversing moving axis is fixed on blind end) between the traversing moving axis or roller of this end, close in a fixed manner by traversing moving axis and roller, avoid it to continue along guide rail mobile, play the effect of fulcrum.
" free end " alleged by the present invention is the concept relative with above-mentioned " blind end ", namely instructs the other end of rail to be the structure of freely opening wide, and its object is to enable hydraulic push rod stretch in guide rail, pushing rolling wheels and distance rod move.
In order to make those skilled in the art person understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1-3, photovoltaic system automatic push-pull interlock adjustable fixer provided by the invention, the guide rail 1 that two row's C-type steel are made, two row's guide rails 1 be arranged in parallel in a determining deviation, pedestal 2 is provided with below guide rail 1, on the one hand firm effect is played to guide rail 1, guarantee that the level height of two row's guide rails 1 is consistent on the other hand, improve the stability that guide rail 1 works.Guide rail 1 one end is blind end 101, the other end is free end 102, a traversing moving axis 3 vertical with guide rail 1 is respectively set between blind end 101 and two guide rails 1 of free end 102, two traversing moving axis 3 are also provided with between two guide rails 1 between blind end 101 and free end 102, guide rail 1 is provided with roller 4, each traversing moving axis 3 two ends are connected with roller 4 in the mode of bearing fit, and roller 4 is arranged on guide rail 1, and the traversing moving axis 3 except blind end 101 can be driven to move along guide rail 1.
Between adjacent traversing moving axis 3, be provided with photovoltaic bracket 5, thus make multiple photovoltaic bracket 5 form photovoltaic array.Each photovoltaic bracket 5 is arranged in Greek alphabet "∧" type by two cant beams 501, the top of two cant beams 501 is interconnected by hinge, to realize relatively rotating, the downside of bottom is fixedly connected with connector 6, connector 6 is enclosed within traversing moving axis 3 away from one end of cant beam 501, realize relatively rotating between cant beam 501 and traversing moving axis 3, and connector 6 can also play certain support to cant beam 501.When roller 4 drives traversing moving axis 3 to move along guide rail 1, the hinge as fulcrum drives two cant beams 501 to relatively rotate, and namely changes the angle between cant beam 501.Linked together by steel cable 7 in the middle part of the twice cant beam 501 of each photovoltaic bracket 5, the length of each steel wire rope 7 is equal, the limit expanded angle be used between restriction two cant beams 501.
All solar modules 8 be equipped with on the cant beam 501 of sunny slope for receiving solar illuminating radiation, the two ends of each solar module 8 are all fixed on (as shown in Figure 4) on photovoltaic bracket 5 by photovoltaic limit briquetting 502, avoid photovoltaic bracket 5 to cause rocking of solar module 8 in the process changing operating angle.
The equal distance rod of length 9 is provided with between each roller 4 on guide rail 1, the free end 102 of guide rail 1 is also provided with hydraulic push rod 10, hydraulic push rod 10 can move along guide rail 1 by pushing rolling wheels 4, and promote follow-up roller move together by contacting with distance rod 9, because the length of each distance rod 9 is equal, also just ensure that the spacing of each roller 4 keeps equal photovoltaic bracket 5 is pushed to final position, serve spacing effect.
Photovoltaic system automatic push-pull interlock adjustable fixer provided by the invention is divided into two kinds of operating states, one is summer (sunlight direct projection angle becomes large) operating state, and another kind of is winter (sunlight direct projection angle diminishes) operating state.When needs adjustment photovoltaic bracket enters summer operation state, open hydraulic push rod 10, first hydraulic push rod 10 promotes to move along guide rail 1 direction guiding rail blind end 101 near the roller 4 of free end 102, traversing moving axis 3 is also moved along guide rail 1 by roller 4, and photovoltaic bracket cant beam 501 top near guide rail free end 102 is relatively rotated, change the angle between two cant beams 501, and then the irradiating angle changed on sunlight and cant beam 501 between solar module 8, roller 4 promotes distance rod 9 and moves forward, and then change angle by the photovoltaic bracket cant beam 501 that distance rod 9 promotes a few row below, thus achieve the interlock of many row's photovoltaic bracket operating angles.Along with the blind end 101 of each roller 4, traversing moving axis 3 and photovoltaic bracket 5 direction guiding rail gradually moves, between each roller 4 except distance rod 9 again without other spaces time, whole photovoltaic array has been transformed into summer operation state completely; When photovoltaic array is switched to operating state in winter from summer operation state by needs, loosen hydraulic push rod 10, each photovoltaic bracket 5 relies on the self gravitation of cant beam 501 to be slided by the free end 102 of traversing moving axis 3 and roller 4 direction guiding rail 1, angle between each cant beam 501 is also launched thereupon, steel wire rope 7 in each support between two cant beams 501 is straightened gradually, after steel wire rope 7 is fully straightened, the spacing of two cant beams 501 of each photovoltaic bracket 5 is fixing consistent, and the operating angle of photovoltaic array is switched to operating state in winter.
Utilize the structure and working principle of above-mentioned photovoltaic system automatic push-pull interlock adjustable fixer, no matter guide rail comprises how much organize photovoltaic bracket, its operating angle all realizes interlock by hydraulic push rod and regulates, and significantly improves adjustment efficiency.
Above photovoltaic system automatic push-pull interlock adjustable fixer provided by the present invention is described in detail.Apply specific case herein to set forth the principle of invention and execution mode, the explanation of above embodiment just understands core concept of the present invention for helping.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection range of the claims in the present invention.
