[0020] 1. The present invention provides a pile foundation structure of a photovoltaic bracket. By setting a limiting mechanism, when in use, the placement tube is squeezed so that the limiting mechanism is fixed on the inner side of the connecting tube, and the support column is fixed on the limiting mechanism through a fastener, so that the photovoltaic bracket can be easily installed. When disassembling, the limiting rod is first pulled out of the second fixing hole, and then the connecting rod is squeezed inwardly so that the connecting column and the placement tube are separated from each other. Then, when the connecting rod is squeezed inwardly, the connecting rod is separated from the first fixing hole, so that the squeezing spring at the bottom rebounds. When the squeezing spring rebounds, it pushes the fixing hole to be disassembled. The fixed column and the pushing block at the bottom move downward. When the fixed column moves downward, it will pull the upper mounting platform downward, and when the fixed column moves downward, it will pull the outer limiting plate and the extrusion plate 2 to retract inward through the supporting plate, so that the limiting plate and the extrusion plate 2 are separated from the inside of the connecting tube, and the pushing block moves downward, so that the extruded return spring rebounds, thereby pushing the pushing plate to move backward. The movement of the pushing plate drives the outer extrusion plate 1 to move backward through the placing block, so that the extrusion plate is separated from the fixed pile. Therefore, it is convenient to disassemble the limiting mechanism as a whole, and therefore, it is convenient to replace the pile foundation.

[0021] 2. The present invention provides a pile foundation structure for a photovoltaic bracket. Through the setting of an adjusting part, the brake motor works and the output end rotates, driving the transmission rod on one side to rotate. When the transmission rod rotates, it drives the outer gear to rotate. The rotation of the gear drives the installation column on one side to move upward. When the installation column moves upward, it drives the upper installation plate to move upward as a whole. When the photovoltaic bracket is used, it is convenient to adjust the overall height of the photovoltaic bracket according to actual needs. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, through the placement cavity 703, it is convenient to store the extrusion plate 702. A push plate 717 is fixedly installed on the end of the placement block 705 opposite to the extrusion plate 702. A through groove is opened on the inner side of the placement block 705, and a guide rod 719 is fixedly installed on the inner side of the through groove.

Specifically, the placement cylinder 701 is placed inside the connecting cylinder 2. When the push block 709 inside the placement cylinder 701 contacts the bottom of the fixed pile 1, the placement cylinder 701 is pushed as a whole. When the push block 709 is forced to move upward, it will squeeze the outer push plate 717, thereby pushing the push plate 717 to move outward. When the push plate 717 moves outward, it will push the placement block 705 and the extrusion plate 702 to move outward, so that the extrusion plate 702 is tightly against the inner wall of the fixed pile 1, so that the extrusion plate 702 limits the bottom of the placement tube 701, and when the placement block 705 moves, it will squeeze the return spring 718 on the outer side of the guide rod 719, thereby improving the stability of the extrusion plate 702.

When in use, when the push block 709 moves upward, the fixed column 710 located above moves upward synchronously. When the fixed column 710 moves upward, it will push the limit plate 706 to adjust the angle through the support plate 711 arranged on the outside, so that the extrusion plate 2 708 above the limit plate 706 is in contact with the inner wall of the connecting tube 2, and the middle part of the placement tube 701 is fixed by the limit plate 706 and the extrusion plate 2 708.

[0039] Furthermore, the limiting component includes a mounting platform 715, which is fixedly mounted on the top of the connecting column 713. Plug holes 722 are provided around the mounting platform 715. A second placement cavity 724 is provided on the mounting platform 715. The second placement cavity 724 is connected to the plug hole 722. The diameter of the second placement cavity 724 is larger than the diameter of the plug hole 722. A connecting rod 720 is provided on the inner side of the plug hole 722. A limiting plate 725 is fixedly mounted on one end of the connecting rod 720. The limiting plate 725 is arranged on the inner side of the second placement cavity 724. A second fastening spring 723 is fixedly mounted on one end of the limiting plate 725.

A mounting cavity is provided at the bottom of the support column 3. The support column 3 is sleeved on the upper outer side of the placement tube 701 through the mounting cavity. A fixing hole 8 is provided below the placement tube 701 and the support column 3. The connecting rod 720 is arranged on When the locking cam 710 is in the unlocking state, the locking cam 713 is in the unlocking state, and the locking cam 713 is in the unlocking state.

[0040] See also Fig. 9 The present embodiment further includes a fastener 6, which is arranged below the support column 3. The fastener 6 includes a fixing frame 602, inside which a limiting rod 601 is slidably arranged, and the fixing frame 602 is fixedly installed below the support column 3. The support column 3 and the placement tube 701 are both provided with a fixing hole 29, and the limiting rod 601 is inserted into the inside of the fixing hole 29. The diameter of the fixing hole 29 is larger than the diameter of the limiting rod 601. The limiting rod 601 is adapted to the fixing hole 29, so it is convenient to use the limiting rod 601. The support column 3 and the placement tube 701 can be quickly spliced ​​together through the setting of the limiting rod 601. A sliding groove 721 is provided on the upper outer side of the placement tube 701. A slider 301 is fixedly installed on the inner wall of the mounting cavity below the support column 3. The slider 301 is slidably arranged inside the sliding groove 721. Through the mutual limitation of the slider 301 and the sliding groove 721, the support column 3 and the placement tube 701 can be limited during the splicing process. A connecting piece 603 is fixedly installed in the middle of the limiting rod 601. A fastening spring 604 is arranged, and the two ends of the fastening spring 604 are respectively fixedly mounted on the fixing frame 602 and the support column 3. One end of the limit rod 601 passes through the fixing frame 602 and extends to the outside of the fixing frame 602. A pull plate 605 is fixedly mounted on one end of the limit rod 601. The pull plate 605 and the fixing frame 602 are fitted together. When in use, the support column 3 and the upper part of the placement tube 701 are spliced ​​together. When splicing, the limit rod 601 is pulled outward through the pull plate 605 to make the limit rod 601 move backward. When the support column 3 After the splicing with the placement tube 701 is completed, the operator loosens the pull plate 605, thereby resetting the fastening spring 1 604 located on the inside and pushing the connecting piece 603 on one side forward. When the connecting piece 603 moves, it will drive the limiting rod 601 in the middle to move forward, so that the limiting rod 601 enters the fixing hole 2 9 on the support column 3 and the placement tube 701, and the support column 3 and the placement tube 701 are limited by the limiting rod 601, thereby facilitating the splicing of the connecting column 713 and the placement tube 701.

[0041] In this embodiment, when the limiting mechanism 7 needs to be disassembled, the limiting rod 601 is first pulled out of the fixing hole 9, and then the connecting rod 720 is squeezed inwardly, so that the connecting column 713 and the placement tube 701 are separated from each other, and when the connecting rod 720 is squeezed inwardly, the connecting rod 720 is separated from the fixing hole 8, so that the squeezing spring 712 at the bottom rebounds, and when the squeezing spring 712 rebounds, it pushes the fixing column 710 and the pushing block 709 at the bottom to move downward, and when the fixing column 710 moves downward, it pulls the upper mounting platform 715 to move downward. When the fixed column 710 moves downward, the outer limiting plate 706 and the extrusion plate 2 708 will be pulled inward through the support plate 711, so that the limiting plate 706 and the extrusion plate 2 708 are separated from the interior of the connecting tube 2, and the push block 709 moves downward, so that the extruded return spring 718 rebounds, thereby pushing the push plate 717 to move backward. The push plate 717 moves and drives the outer extrusion plate 1 702 to move backward through the placement block 705, so that the extrusion plate is separated from the fixed pile 1, thereby facilitating the disassembly of the limiting mechanism 7 as a whole.

[0042] The working principle of the pile foundation structure of the photovoltaic support provided by the present invention is as follows:

[0043] The first step: When using the pile foundation of the photovoltaic bracket, first bury the fixed pile 1 and the connecting tube 2 deep underground. After completion, pour concrete around the outside of the fixed pile 1 to improve the stability of the fixed pile 1.

[0044] Then the support column 3 and the upper part of the placement tube 701 are spliced ​​together. During the splicing, the support column 3 and the placement tube 701 are limited by the mutual limitation of the slider 301 and the slide groove 721, and the limiting rod 601 is pulled outward by the pull plate 605 to move the limiting rod 601 backward. When the support column 3 and the placement tube 701 are spliced, the operator releases the pull plate 605, so that the fastening spring 1 604 located on the inner side is reset, and the connecting piece 603 on one side is pushed forward. When the connecting piece 603 moves, it will drive the limiting rod 601 in the middle to move forward, so that the limiting rod 601 enters the fixing hole 2 9 on the support column 3 and the placement tube 701, and the support column 3 and the placement tube 701 are limited by the limiting rod 601.

[0045] The second step: after the splicing is completed, the placement tube 701 is placed into the connecting tube 2. When the push block 709 on the inside of the placement tube 701 contacts the bottom of the fixed pile 1, the placement tube 701 is squeezed as a whole, so that the push block 709 on the inside is forced to move upward. When the push block 709 is forced to move upward, it will squeeze the push plate 717 on the outside, thereby pushing the push plate 717 to move outward. When the push plate 717 moves outward, it will push the placement block 705 and the extrusion plate 702 to move outward, so that the extrusion plate 702 is tightly against the inner wall of the fixed pile 1, so that the extrusion plate 702 limits the bottom of the placement tube 701, and when the placement block 705 moves, it will squeeze the return spring 718 on the outside of the guide rod 719 to improve the stability of the extrusion plate 702.

[0046] When the push block 709 moves upward, the fixed column 710 located above moves upward synchronously. When the fixed column 710 moves upward, it will push the limiting plate 706 to adjust the angle through the support plate 711 arranged on the outside, so that the extrusion plate 2 708 above the limiting plate 706 fits with the inner wall of the connecting tube 2, and the middle part of the placing tube 701 is fixed by the limiting plate 706 and the extrusion plate 2 708.

[0047] When the fixing column 710 moves upward, it will push the upper connecting column 713 to move upward synchronously. When the connecting column 713 moves upward, it will squeeze the extrusion spring 712, causing the extrusion spring 712 to contract. At the same time, when the connecting column 713 moves upward, the mounting platform 715 located at the top will also move upward. When the mounting platform 715 moves upward to the fixing hole 18 opened by the support column 3 and the placement tube 701, the fastening spring 2 723 located inside the mounting platform 715 releases the pressure, thereby pushing the connecting rod 720 to move outward in the plug-in hole 722, so that the connecting rod 720 enters the fixing hole 18, which is used to limit the top of the placement tube 701.

[0048] At the same time, the support column 3 and the placement tube 701 are limited by the connecting rod 720, and the limiting mechanism 7 as a whole can be limited at the same time, so that the limiting mechanism 7 is fixedly installed inside the connecting tube 2.

[0049] When the limiting mechanism 7 needs to be disassembled, the limiting rod 601 is first pulled out of the fixing hole 2 9 , and then the connecting rod 720 is pressed inwardly so that the connecting column 713 and the placing tube 701 are separated from each other.

[0050] When the connecting rod 720 is squeezed inwardly, the connecting rod 720 is disengaged from the fixing hole 8, so the squeezing spring 712 at the bottom rebounds. When the squeezing spring 712 rebounds, it pushes the fixing column 710 and the pushing block 709 at the bottom to move downward. When the fixing column 710 moves downward, it pulls the upper mounting platform 715 to move downward, and when the fixing column 710 moves downward, it pulls the outer limiting plate 706 and the squeezing plate 2 708 to retract inwardly through the support plate 711, thereby making the limiting plate 706 and the squeezing plate 2 708 disengage from the inside of the connecting tube 2, and the pushing block 709 moves downward, so that the squeezed return spring 718 rebounds, thereby pushing the pushing plate 717 to move backward. The pushing plate 717 moves and drives the outer squeezing plate 1 702 to move backward through the placing block 705, so that the squeezing plate is separated from the fixing pile 1, thereby facilitating the disassembly of the limiting mechanism 7 as a whole.

[0051] Compared with the related art, the pile foundation structure of the photovoltaic support provided by the present invention has the following beneficial effects:

[0052] 1. The present invention provides a pile foundation structure of a photovoltaic bracket. By setting a limiting mechanism 7, when in use, the placement tube 701 is squeezed so that the limiting mechanism 7 is fixed on the inner side of the connecting tube 2, and the support column 3 is fixed on the limiting mechanism 7 through the fastener 6, so as to facilitate the installation of the photovoltaic bracket. When disassembling, first, the limiting rod 601 is pulled out of the fixing hole 9, and then the connecting rod 720 is squeezed inwardly so that the connecting column 713 and the placement tube 701 are separated from each other. Then, when the connecting rod 720 is squeezed inwardly, the connecting rod 720 is separated from the fixing hole 8, so that the squeezing spring 712 at the bottom rebounds. When the squeezing spring 712 rebounds, it pushes the fixing column 710 and the bottom The push block 709 moves downward, and when the fixed column 710 moves downward, it will pull the upper mounting platform 715 to move downward, and when the fixed column 710 moves downward, it will pull the outer limiting plate 706 and the extrusion plate 2 708 to retract inward through the support plate 711, so that the limiting plate 706 and the extrusion plate 2 708 are separated from the inside of the connecting tube 2, and the push block 709 moves downward, so that the extruded return spring 718 rebounds, thereby pushing the push plate 717 to move backward, and the push plate 717 moves through the placement block 705 to drive the outer extrusion plate 1 702 to move backward, so that the extrusion plate is separated from the fixed pile 1, thereby facilitating the disassembly of the limiting mechanism 7 as a whole, and thus facilitating the replacement of the pile foundation.

[0053] 2. The present invention provides a pile foundation structure of a photovoltaic bracket. Through the setting of the adjustment member 4, the brake motor 403 works, and the output end rotates, driving the transmission rod 405 on one side to rotate. When the transmission rod 405 rotates, it will drive the outer gear 404 to rotate. The rotation of the gear 404 will drive the installation column 401 on one side to move upward. When the installation column 401 moves upward, it will drive the upper installation plate 5 to move upward as a whole. When the photovoltaic bracket is used, it is convenient to adjust the overall height of the photovoltaic bracket according to actual needs.
