With the above embodiments, the usage principle and working process of the present invention are as follows:
the invention relates to a supporting structure of a movable photovoltaic power generation assembly, which is characterized in that when a photovoltaic panel 200 is installed, breeze or windless clear weather is selected, and the wind power is prevented from influencing the installation process. The support leg 300 is fixedly installed on the ground 100. And the heights of the plurality of supporting legs 300 are adjusted according to the sunlight angle, so that the sunlight is directly irradiated to the photovoltaic panel 200, when the supporting rod 400 is pressed by the photovoltaic panel 200, the supporting rod 400 moves downwards relative to the annular fixture block 500 to drive the upper mounting ring 860 and the lower mounting ring 870 to synchronously move downwards, at this time, because the upper hinge column 850 can only slide in the upper chute 511 and the lower hinge column 850 can only slide in the lower chute 512, the upper mounting ring 860 and the lower mounting ring 870 move downwards to drive the upper hinge column 850 to slide towards the position far away from the supporting rod 400 and the lower hinge column 850 slides towards the position close to the supporting rod 400, and the sliding distance of the lower hinge column 850 is greater than that of the upper hinge column 850. And because the clamping rod 840 is slidably mounted in the sliding rail 513, and the sliding rail 513 is located at a middle position of the upper sliding groove 511 and the lower sliding groove 512 in the vertical direction, the sliding of the upper hinge column 850 and the lower hinge column 850 drives the clamping rod 840 to approach the supporting rod 400. At this time, locking bolt 640 is rotated to bring the tightening bolt into contact with turntable 600, and turntable 600 cannot rotate relative to support leg 300, and the mounting operation is completed. In the installation process, when the height of the supporting leg 300 is adjusted, the supporting rod 400 moves downwards relative to the supporting leg 300 to drive the annular clamping block 500 to move downwards and drive the rotary table 600 to move downwards, so that the supporting spring 630 compresses to store force. The heavier the photovoltaic panel 200, the greater the compression of the supporting spring 630, and the greater the downward movement of the turntable 600. Since the rotary slider 620 is slidably mounted in the rotary groove 320, the rotary table 600 rotates while moving downward relative to the support leg 300, thereby driving the spiral latch 610 to rotate. When the weight of the photovoltaic panel 200 is larger, the rotation angle of the spiral clamp 610 is larger, that is, no matter how large the weight of the photovoltaic panel 200 is, the end of the clamp rod 840 far away from the support rod 400 is clamped above the spiral clamp 610 by a predetermined length.
When the photovoltaic panel 200 is subjected to the blowing force of wind, the support rod 400 is subjected to downward pressure, and when the blowing force of the wind is larger, the pressure applied to the support rod 400 is larger. When bracing piece 400 atress moved down, the drive was gone up the collar 860 and is moved down with collar 870 in step, go up articulated post 850 and keep away from bracing piece 400, articulated post 850 is close to bracing piece 400 down, continue to drive kelly 840 inward movement, supporting leg 300 is when receiving wind-force, turn into the vertical vibrations of bracing piece 400 connecting rod 830 center and the horizontal migration of kelly 840, and when last articulated post 850 and articulated post 850 slide down, the bracing subassembly 900 with the two contact provides the buffering for the two respectively, and guarantee that bracing piece 400 and supporting leg 300 are in coaxial and contactless state all the time, avoided the support vibration wearing and tearing that cause because external factors. When the wind power borne by the photovoltaic panel 200 is larger, the inward movement amount of the clamping rod 840 is larger, when the wind power is large to a certain degree, the inward movement amount of the clamping rod 840 is larger than the length of the clamping rod clamped on the spiral clamping block 610 in the initial state, the clamping rod 840 is separated from the spiral clamping block 610, the supporting rod 400 is separated from the contact with the annular clamping block 500, the supporting rod 400 loses the supporting force and then moves downwards to the annular clamping block 500, the hydraulic valve 700 is contacted and triggered, after the hydraulic valve 700 is triggered, the supporting leg 300 is slowly shortened, the supporting leg 300 below the photovoltaic panel 200 is successively shortened, and the photovoltaic panel 200 is gradually changed into the horizontal state. The wind power can be automatically judged, the influence of strong wind weather is avoided, and the damage to the photovoltaic panel 200 caused by severe weather is avoided.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
