[0005] The utility model provides a photovoltaic bracket with stable height adjustment, which solves the problem of unstable support after the height of the column is adjusted.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A photovoltaic bracket with stable height adjustment, the photovoltaic bracket is provided with a plurality of columns, the columns include column bodies and column feet, the column feet include sleeve bases, the bottom of the column bodies are inserted into the sleeve bases, a height adjustment structure for adjusting the relative height of the column bodies and the sleeve bases is provided between the column bodies and the sleeve bases, the columns are also provided with a reinforced support assembly for supporting the column bodies after the height adjustment structure is adjusted.

[0008] Preferably, a horizontal through fixing hole is provided at the bottom of the column body, and adjustment grooves extending up and down are provided on the opposite side walls of the sleeve base corresponding to the position of the fixing hole, and the height adjustment structure is provided with a horizontal fastener for fixing the column body and the sleeve base in a horizontal direction, and the horizontal fastener passes through the fixing hole and the adjustment groove.

[0009] Preferably, the horizontal fastener is a through-column bolt, which fixes the column body and the sleeve base, and first nuts are provided at both ends of the through-column bolt.

[0010] Preferably, the sleeve base is arranged on a fixed base plate, and the reinforced support assembly includes an intermediate connecting piece and a vertical fastener arranged on the outside of the sleeve base, the intermediate connecting piece connects the through-column bolt and the vertical fastener, and the vertical fastener is supported on the fixed base plate and fixes the intermediate connecting piece vertically.

[0011] Preferably, the intermediate connecting member includes a vertical portion connected to the through-column bolt and a supporting portion perpendicular to the vertical portion, the vertical portion is provided with an upper fixing hole, the upper fixing hole is connected to the through-column bolt, and the supporting portion is supported on the vertical fastener.

[0012] Preferably, the vertical fastener is a fixing bolt, the support portion is provided with a lower fixing hole, the fixing bolt passes through the lower fixing hole and nuts are connected to the upper and lower sides of the lower fixing hole; and / or, a reinforced support assembly is provided on opposite sides of the sleeve base corresponding to the fixing hole position.

[0013] Preferably, the vertical fasteners are welded and fixed to the fixed base plate.

[0014] Preferably, the intermediate connecting member is made of aluminum alloy or stainless steel profile; and / or a gasket is provided between the through-column bolt and the upper fixing hole.

[0015] Preferably, the sleeve base is arranged on a fixed bottom plate, and a reinforced rib is provided between the fixed bottom plate and the sleeve base.

[0016] Preferably, the sleeve base and the column body are both square tubes.

[0017] The utility model adopts the above technical solution and has the following beneficial effects:

[0018] 1. A height adjustment structure is provided between the column body and the column foot. The column body is inserted into the sleeve base. The relative height between the column body and the sleeve base is adjusted through the height adjustment structure to achieve the height adjustment of the column. Compared with the prior art, when there is an elevation deviation of the foundation pouring on site, a processing deviation of the column length, or a temporary fine-tuning of the photovoltaic panel surface angle on site, either the height of some columns can be adjusted to eliminate the deviation, and the installation can still be carried out normally, or the height of all columns can be adjusted as a whole to achieve temporary fine-tuning of the photovoltaic panel surface angle on site.

[0019] The height adjustment structure of the prior art usually uses horizontal fasteners to fix the column body and the sleeve base in the horizontal direction. However, after long-term use or exposure to wind load disturbance, high and low temperature reciprocating cycles and other external influences, the connection parts between the horizontal fasteners and the column body and the sleeve base are prone to connection fatigue loosening and thermal expansion and contraction loosening, resulting in failure of the height adjustment structure. Under the action of gravity, the column body moves downward, affecting the overall stability of the photovoltaic bracket. Therefore, the utility model is provided with a reinforced support component, which supports the column body after the height adjustment component completes the height adjustment. Even if the height adjustment structure fails, the column body still maintains its original height due to the support of the reinforced support component, solving the problem of unstable support after the height adjustment of the column.

[0020] 2. A fixing hole is provided at the bottom of the column body, and adjustment grooves extending up and down are provided on the opposite side walls of the sleeve base corresponding to the fixing hole. The horizontal fasteners pass through the fixing holes and the adjustment grooves. When the horizontal fasteners are loosened, the column body can move up and down relative to the sleeve base to achieve the overall height adjustment of the column. After adjustment, the horizontal fasteners can be tightened, so it is convenient to adjust the height of the column.

[0021] 3. The horizontal fastener is a through-column bolt. After the height of the column is adjusted to the right position, tighten the first nuts on both sides to lock the column body and the sleeve base. When the height needs to be adjusted, loosen the nuts. It is convenient for adjustment and the locking is reliable.

[0022] 4. The enhanced support assembly includes an intermediate connector and a vertical fastener, wherein the intermediate connector connects the column bolt and the vertical fastener, and the vertical fastener fixes the intermediate connector vertically. When the column moves up and down relative to the sleeve base, the column bolt moves up and down with it, driving the intermediate connector to move up and down synchronously. Therefore, as long as the vertical fastener fixes the intermediate connector vertically, the vertical position of the column can be fixed. In addition, the enhanced support assembly is arranged outside the sleeve base, which can facilitate the tightening and loosening of the vertical fastener.

[0023] 5. The middle connecting piece is an L-shaped structure, including a vertical part and a supporting part, wherein the vertical part is provided with an upper fixing hole connected to a through-column bolt, and the supporting part is supported on the vertical fastener, so when the column body moves up and down, the through-column bolt and the middle connecting piece are driven to move up and down. Since the supporting part is supported on the vertical fastener, the vertical position of the column body can be fixed.

[0024] 6. The vertical fastener is a fixing bolt, which passes through the lower fixing hole set on the support part. Nuts are connected to the upper and lower sides of the lower fixing hole. The vertical position of the support part can be locked and fixed by the nuts.

[0025] Since a reinforcing support assembly connected with the column-penetrating bolts is arranged on opposite sides of the sleeve base corresponding to the fixing hole position, the support for the column body is more stable and reliable.

[0026] 7. The fixing bolts are welded and fixed to the fixed base plate. Not only is the fixation reliable, but also after the fixing bolts are fixed to the fixed base plate, when the column moves up and down, the lower fixing hole moves up and down along the fixing bolts. Finally, the nuts on the upper and lower sides of the fixing hole are tightened and fixed.

[0027] 8. The intermediate connector is made of aluminum alloy or stainless steel, which is not only corrosion-resistant, but also has high strength and long service life. At the same time, it can be industrially produced on a large scale, which is conducive to reducing costs;

[0028] A gasket is provided between the through-column bolt and the upper fixing hole, and a gasket is provided between the fixing bolt and the lower fixing hole, which can increase reliability and prevent loosening.

[0029] 9. A reinforced rib is provided between the fixed base plate and the sleeve base to enhance the connection strength between the fixed base plate and the sleeve base.

[0030] 10. Similar to the prior art, the sleeve base is a square tube, and the column is also a square tube, so that there is no relative rotation between the sleeve base and the column, and the structure is stable.

[0031] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings.

[0048] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0049] Reference Figures 1 to 10 As shown, this embodiment provides a photovoltaic bracket with stable height adjustment, wherein the photovoltaic bracket is provided with a plurality of columns for vertical support, wherein the columns include a column body 2 and a column foot 1, wherein the column foot 1 includes a fixed bottom plate 11 and a sleeve base 12 provided on the fixed bottom plate, and the bottom of the column body 2 is inserted into the sleeve base 12. A height adjustment structure for adjusting the relative height between the column body and the sleeve base is provided between the column body 2 and the sleeve base 12.

[0050] There are many implementation forms of the height adjustment structure in the prior art. In this embodiment, the height adjustment structure is provided with a horizontal fastener for fixing the column body and the sleeve base in the horizontal direction.

[0051] In order to solve the problem of unstable support after the height adjustment of the column using the height adjustment structure, the column is also provided with a reinforced support component to support the column body after the height adjustment structure is adjusted. Specifically, a reinforced support component can be set between the horizontal fastener and the fixed base plate 11, and the reinforced support component supports the horizontal fastener after the horizontal fastener is tightened.

[0052] A height adjustment structure is provided between the column body and the column foot. The column body is inserted into the sleeve base. The relative height between the column body and the sleeve base is adjusted through the height adjustment structure to achieve the height adjustment of the column. Compared with the prior art, when there is a deviation in the elevation of the foundation casting on site, a deviation in the column length processing, or a temporary fine-tuning of the photovoltaic panel surface angle on site, either the height of some columns can be adjusted to eliminate the deviation, and the installation can still be carried out normally, or the height of all columns can be adjusted as a whole to achieve temporary fine-tuning of the photovoltaic panel surface angle on site.

[0053] The height adjustment structure of the prior art usually uses horizontal fasteners to fix the column body and the sleeve base in the horizontal direction. However, after long-term use or exposure to wind load disturbance, high and low temperature reciprocating cycles and other external influences, the connection parts between the horizontal fasteners and the column body and the sleeve base are prone to connection fatigue loosening and thermal expansion and contraction loosening, resulting in failure of the height adjustment structure. Under the action of gravity, the column body moves downward, affecting the overall stability of the photovoltaic bracket. Therefore, the utility model is provided with a reinforced support component, which supports the column body after the height adjustment component completes the height adjustment. Even if the height adjustment structure fails, the column body still maintains its original height due to the support of the reinforced support component, solving the problem of unstable support after the height adjustment of the column.

[0054] Referring to the prior art, a common height adjustment structure is taken as an example. Specifically, a horizontal through-going fixing hole 21 is provided at the bottom of the column body, and the opposite side walls of the sleeve base 12 corresponding to the fixing hole position are provided with adjustment grooves 121 extending up and down, and the horizontal fastener passes through the fixing hole 21 and the adjustment groove 121. The horizontal fastener is a through-column bolt 3, which fixes the column body and the sleeve base. The through-column bolt includes a through-column screw rod 31, which is a double-headed screw rod, and a first nut 32 is connected at both ends. When the horizontal fastener is loosened, the column body can move up and down relative to the sleeve base to achieve the overall height adjustment of the column. After the adjustment is in place, the horizontal fastener can be tightened, that is, the first nuts on both sides are tightened, so that the height adjustment of the column is convenient, and the locking and fixing is reliable.

[0055] It is understandable that the height adjustment structure may also adopt other structures, such as a threaded hole is provided on the sleeve base, and a locking screw is screwed into the threaded hole to lock and fix the column. Of course, the enhanced support assembly is not limited to supporting horizontal fasteners, but can also support the column. In the case where the adjustment range is not large, a spring can be provided for enhanced support.

[0056] The reinforcing support assembly includes an intermediate connector 4 and a vertical fastener, and is arranged outside the sleeve base. The intermediate connector 4 connects the through-column bolt 3 and the vertical fastener, and the vertical fastener fixes the intermediate connector in the vertical direction. When the column body moves up and down relative to the sleeve base, the through-column bolt follows the up and down movement, driving the intermediate connector to move up and down synchronously. Therefore, as long as the vertical fastener fixes the intermediate connector in the vertical direction, the vertical position of the column body can be fixed. When the height needs to be adjusted, the vertical fastener and the intermediate connector can be loosened. In addition, since the reinforcing support assembly is arranged outside the sleeve base, the tightening and loosening of the vertical fastener can be facilitated.

[0057] Specifically, the intermediate connecting member 4 includes a vertical portion 41 connected to the through-column bolt and a supporting portion 42 perpendicular to the vertical portion. The vertical portion 41 is provided with an upper fixing hole, the upper fixing hole is connected to the through-column bolt 3, and the supporting portion 42 is supported on the vertical fastener. Therefore, when the column body moves up and down, the through-column bolt and the intermediate connecting member are driven to move up and down. Since the supporting portion is supported and fixed on the vertical fastener, the vertical position of the column body can be fixed.

[0058] In this embodiment, the vertical fastener is a fixing bolt 5, and the support portion 42 is provided with a lower fixing hole. The fixing bolt 5 passes through the lower fixing hole and is connected to the upper and lower sides of the lower fixing hole with a second nut 53. The fixing bolt 5 includes a fixing screw 51, which is usually provided with threads. During initial installation, the height of the column is fixed, the fixing bolt passes through the lower fixing hole and is connected to the upper and lower sides of the lower fixing hole with a second nut 53, and the vertical position of the support portion can be locked and fixed by tightening the second nut.

[0059] Furthermore, the fixing bolt 5 is welded and fixed to the fixing base plate 11, that is, the bottom end of the fixing screw 51 is welded and fixed to the fixing base plate 11. During initial installation, a second nut 53 is firstly threadedly sleeved on the fixing screw, and then the fixing screw passes through the lower fixing hole and is connected to a second nut 53 on the upper side of the lower fixing hole. At this time, a second nut 53 is connected to the upper and lower sides of the lower fixing hole. The welding method ensures that the fixing bolt is fixed reliably. After the fixing bolt is fixed to the fixing base plate, when the column moves up and down, the lower fixing hole moves up and down along the fixing bolt, and finally the second nuts on the upper and lower sides of the fixing hole are locked and fixed.

[0060] In this embodiment, a reinforcing support assembly connected with the column bolts is provided on opposite sides of the sleeve base corresponding to the fixing hole position, so that the support for the column body is more stable and reliable.

[0061] In order to prevent the through-column bolt and the fixing bolt from loosening, a first gasket 33 is provided between the through-column bolt 3 and the upper fixing hole, and a second gasket 52 is provided between the fixing bolt 5 and the lower fixing hole.

[0062] The intermediate connecting member 4 is made of aluminum alloy or stainless steel, which is not only corrosion-resistant but also has high strength and long service life. At the same time, it can be industrially produced on a large scale, which is conducive to reducing costs.

[0063] Referring to the prior art, the sleeve base 12 is a square tube, and the column body 2 is a square tube. There is no relative rotation between the sleeve base and the column body, and the structure is stable. In addition, a reinforced rib 13 is provided between the fixed base plate 11 and the sleeve base 12. The reinforced rib is a right-angled trapezoidal plate, which is arranged at the four corners of the fixed base plate. At each corner, two reinforced ribs 13 are arranged at right angles and are welded and fixed to the fixed base plate and the sleeve base. The fixed base plate is connected with mounting bolts 14 for fixing the column to the foundation.

[0064] Other structures of the photovoltaic bracket can refer to the existing technology. Taking a common photovoltaic bracket as an example, the photovoltaic bracket also includes a number of inclined beams and a number of cross beams fixed vertically cross the several inclined beams, a number of photovoltaic components are fixed to the cross beams, and the upper ends of the columns are connected to the inclined beams.

[0065] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
