In order to leave enough space at the bottom of the photovoltaic brackets for agricultural production, the existing photovoltaic brackets are getting higher and higher, making the installation of photovoltaic components more and more difficult. Ladders are needed to climb up before installation. Summary of the invention

[0004] The purpose of the present invention is to provide a mountain photovoltaic support structure with unfolded sides to solve the problem raised in the above-mentioned background technology that the existing photovoltaic support is a fixed structure with an integrated installation beam. In order to leave enough space at the bottom of the photovoltaic support for agricultural production, the existing photovoltaic supports are made higher and higher, which makes the installation of photovoltaic components more and more difficult and requires the use of ladders and the like to climb up before installation.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is a two-side unfolded mountain photovoltaic support structure, comprising: A base and a sleeve rod, the sleeve rod is fixedly connected to the middle position of the upper side of the base, the inner side of the sleeve rod is slidably connected to a support rod, and the upper end of the support rod is hinged to a crossbeam; The connecting component includes a left connecting block fixedly connected to the left end of the lower side of the beam, a right connecting block fixedly connected to the right end of the lower side of the beam, fixing bolts are internally connected to the left connecting block and the right connecting block, nuts are threadedly connected to the outer ends of the fixing bolts, and closing plates are connected to the outer ends of the left connecting block and the right connecting block, a card frame is fixedly connected to the side of the closing plate close to the left connecting block or the right connecting block, and a handle is fixedly connected to the side of the closing plate away from the card frame.

[0006] Furthermore, the right side of the left connecting block abuts against the left side of the right connecting block, grooves are symmetrically provided on the farthest side of the left connecting block and the right connecting block, a through hole is provided in the middle position inside the left connecting block and the right connecting block, and the outer side of the fixing bolt is slidably connected to the inner side of the through hole.

[0007] Furthermore, the outer side of the clamping frame is clamped with the inner sides of the grooves on the inner sides of the left connecting block and the right connecting block.

[0008] Furthermore, an adjustment unit is connected to the inner side of the sleeve rod, and the adjustment unit includes sliding blocks fixedly connected to the left and right ends of the lower outer side of the support rod, a retaining ring is fixedly connected to the upper side of the sleeve rod, a motor is installed at the upper front end of the base, and a driving bevel gear is fixedly connected to the rear end of the output shaft of the motor, a bearing is installed at the middle position of the inner upper end of the base, a threaded rod is fixedly connected to the inner side of the bearing, and a driven bevel gear is fixedly connected to the outer lower end of the threaded rod.

[0009] Furthermore, vertical limiting grooves are symmetrically provided at the left and right ends of the inner side of the sleeve rod, and the outer side of the sliding block is slidably connected to the inner side of the limiting groove.

[0010] Furthermore, the lower side of the retaining ring abuts against the upper side of the sliding block.

[0011] Furthermore, the driving bevel gear is meshed with the driven bevel gear, a vertical thread groove is provided at the inner middle position of the support rod, and the outer side of the threaded rod is threadedly connected with the inner side of the thread groove.

[0012] Compared with the prior art, the advantages of the present invention are: According to the present invention, when installing the photovoltaic panel above the crossbeam, the cover plate is first removed from the outer ends of the left connecting block and the right connecting block by pulling the handle, and then the fixing bolts and nuts are relatively rotated to remove them from the inner sides of the left connecting block and the right connecting block. At this time, the left connecting block and the right connecting block are no longer relatively fixed, and the two adjacent crossbeams are no longer relatively fixed. At this time, the crossbeam is rotated around the upper end of the support rod to tilt it downward, and the photovoltaic panel can be installed to the upper end of the crossbeam at a low position. After the installation is completed, the crossbeam is rotated again to keep it horizontal, and then the fixing bolts and nuts are reconnected to the inside of the connected left connecting block and the right connecting block, so that the crossbeam can be kept horizontal again, so that the photovoltaic bracket does not need to be always at a high place for installation work when installing the photovoltaic panel, which makes the installation work more convenient and improves the safety of the installation work.

[0013] Based on the above beneficial effects, when the output shaft of the starting motor rotates to drive the active bevel gear to rotate, the driven bevel gear can be driven to rotate so that the threaded rod rotates, thereby driving the support rod to move along the inner side of the sleeve rod, and at the same time driving the upper crossbeam to move together, so as to change the overall height of the sleeve rod and the support rod at different positions, and adjust the photovoltaic panel installed above the upper crossbeam to a suitable angle to receive light.

[0019] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] See also Figure 1-6 As shown, this embodiment is a two-side unfolded mountain photovoltaic support structure, including: A base 1 and a sleeve rod 2, wherein the sleeve rod 2 is fixedly connected to the middle position of the upper side of the base 1, a support rod 3 is slidably connected to the inner side of the sleeve rod 2, and a crossbeam 4 is hinged at the upper end of the support rod 3; The connecting component includes a left connecting block 51 fixedly connected to the left end of the lower side of the cross beam 4, a right connecting block 52 fixedly connected to the right end of the lower side of the cross beam 4, a fixing bolt 53 is connected inside the left connecting block 51 and the right connecting block 52, a nut 54 is threadedly connected to the outer side of the fixing bolt 53, a sealing plate 55 is connected to the outer end of the left connecting block 51 and the right connecting block 52, a clamping frame 57 is fixedly connected to the side of the sealing plate 55 close to the left connecting block 51 or the right connecting block 52, a handle 56 is fixedly connected to the side of the sealing plate 55 away from the clamping frame 57, the right side of the left connecting block 51 abuts against the left side of the right connecting block 52, a groove is symmetrically provided on the farthest side of the left connecting block 51 and the right connecting block 52, a through hole is provided in the middle position of the inner side of the left connecting block 51 and the right connecting block 52, and the outer side of the fixing bolt 53 is slidably connected to the inner side of the through hole; By passing the fixing bolt 53 through the through holes inside the left connecting block 51 and the right connecting block 52, and then threading the nut 54 to the outside of the fixing bolt 53 until the nut 54 contacts the inside of the groove, the left connecting block 51 and the nut 54 can be relatively fixed.

[0021] The outer side of the clamping frame 57 is clamped with the inner side of the grooves on the inner side of the left connecting block 51 and the right connecting block 52; After the left connecting block 51 and the right connecting block 52 are relatively fixed, the card frame 57 is carded to the inner side of the groove, so that the sealing plate 55 is fixed to the outer side of the left connecting block 51 and the right connecting block 52, and the groove can be closed to prevent the fixing bolts 53 and nuts 54 from contacting water vapor in the outside air and rusting quickly.

[0022] Working principle: when installing the photovoltaic panel on the photovoltaic bracket, first pull the handle 56 to remove the sealing plate 55 from the outer ends of the left connecting block 51 and the right connecting block 52, then rotate the fixing bolts 53 and the nuts 54 relatively to remove them from the inner sides of the left connecting block 51 and the right connecting block 52, and then rotate the beam 4 around the upper end of the support rod 3 so that it tilts downward. Then the staff installs the photovoltaic panel to the upper end of the beam 4 at a low position. After the installation is completed, the beam 4 is rotated back to keep it horizontal, and then the fixing bolts 53 and the nuts 54 are reconnected to the inside of the connected left connecting block 51 and the right connecting block 52, and finally the card frame 57 is slid into the groove. At the same time, the sealing plate 55 is located at the outer ends of the left connecting block 51 and the right connecting block 52 to complete the installation of the photovoltaic bracket.

[0023] See also Figure 1-6As shown, this embodiment is based on the above-mentioned embodiment 1 and further includes an adjusting component, which includes sliders 61 fixedly connected to the left and right ends of the lower outer side of the support rod 3, a retaining ring 62 fixedly connected to the upper side of the sleeve rod 2, a motor 63 is installed at the front end of the upper side of the base 1, and a driving bevel gear 64 is fixedly connected to the rear end of the output shaft of the motor 63. A bearing 65 is installed at the middle position of the upper end of the base 1, a threaded rod 66 is fixedly connected to the inner side of the bearing 65, and a driven bevel gear 67 is fixedly connected to the outer lower end of the threaded rod 66. Vertical limit grooves are symmetrically provided at the left and right ends of the inner side of the sleeve rod 2, and the outer side of the slider 61 is slidably connected to the inner side of the limit groove.

[0024] When the support rod 3 slides along the inner side of the sleeve rod 2, the slider 61 on the outer side of the support rod 3 can only slide along the inner side of the limiting groove, so that the support rod 3 can only be located inside the sleeve rod 2 and translate along the vertical direction, and cannot be located inside the sleeve rod 2 and rotate.

[0025] The lower side of the retaining ring 62 abuts against the upper side of the slider 61; When the slider 61 moves upward along the inner side of the slide groove, it will eventually be blocked by the blocking ring 62 and will not move out of the upper slide groove, so that the support rod 3 will not move out of the inner side of the sleeve rod 2.

[0026] The driving bevel gear 64 is meshed with the driven bevel gear 67, a vertical thread groove is provided in the middle of the inner portion of the support rod 3, and the outer side of the threaded rod 66 is threadedly connected with the inner side of the thread groove; By starting the motor 63, the output shaft of the motor 63 rotates to drive the active bevel gear 64 to rotate, which can drive the driven bevel gear 67 to rotate and make the threaded rod 66 rotate, thereby driving the support rod 3 to move along the inner side of the sleeve rod 2, and at the same time driving the upper end beam 4 to move together, so as to change the overall height of the sleeve rod 2 and the support rod 3 at different positions, and adjust the photovoltaic panel installed above the upper end beam 4 to a suitable angle to receive light.

[0027] Working principle: after the photovoltaic panel is installed, the output shaft of the starting motor 63 rotates to drive the active bevel gear 64 to rotate, thereby driving the driven bevel gear 67 to rotate and causing the threaded rod 66 to rotate, thereby driving the support rod 3 to move along the inner side of the sleeve rod 2, and at the same time driving the upper end of the beam 4 to move together, so that the height of one end of the photovoltaic panel changes until the photovoltaic panel rotates to an angle suitable for receiving light.
