SPECIFIC EMBODIMENTS

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] A detachable and adjustable photovoltaic support, comprising a pressing block 2, purlins 3, a support 14, a steel beam 4, a beam-column connecting piece, a front support column 6, a rear support column 11, a front support bracket 7, a rear support bracket 10, a base 8, a towing ring 9 and a flat laying connecting piece 13. Towing rings 9 are installed at both ends of the base 8. A front support bracket 7 and a rear support bracket 10 are installed on the top of the base 8. Bolt holes are provided on the front support bracket 7 and the rear support bracket 10. The bolt hole on the front support bracket 7 is connected to one end of the front support column 6 by a bolt, and the other end of the front support column 6 is connected to the beam-column connecting piece A5 by a bolt. The beam-column connecting piece A5 is welded to the bottom of the steel beam 4. The bolt hole on the rear support bracket 10 is connected to one end of the rear support column 11 by a bolt, and the other end of the rear support column 11 is connected to the beam-column connecting piece B12 by a bolt. The beam-column connecting piece B12 is welded to the bottom of the steel beam 4. A support column folding connecting piece 15 is installed at the bottom of the steel beam 4, and bolt holes A1501 and bolt holes B1502 are provided on the support column folding connecting piece 15. The bolt hole A1501 is connected to one end of the front support column 6 away from the beam-column connecting piece A5 by a bolt, and the bolt hole B1502 is connected to one end of the rear support column 11 away from the beam-column connecting piece B12 by a bolt. A flat laying connecting piece 13 is welded to one end of the bottom of the steel beam 4. Purlins 3 are distributed on the top of the steel beam 4. The purlins 3 are fixed to the top of the steel beam 4 by the support 14. The support 14 is cross-fixed, and the end of the support 14 is fixed to the steel beam 4 by a bolt. The photovoltaic cell module 1 is fixed to the top of the purlins 3 by the pressing block 2.

[0022] The base 8 is made of steel pipe or reinforced concrete.

[0023] The end section of the base 8 is outwards inclined or the end is bent upwards.

[0024] There are no less than 4 towing rings 9 for each detachable unit.

[0025] There are 2 bolts provided at the lower part of the front support column 6.

[0026] There is 1 bolt provided at the lower part of the rear support column 11.

[0027] The included angle between the rear support column 11 and the steel beam 4 is 90°.

[0028] The end of the support 14 is fixed to the steel beam 4 by a turnbuckle bolt.

[0029] A detachable and adjustable photovoltaic support. The photovoltaic cell module 1 is fixed to the purlin 3 through the pressing block 2. A cross bracing 14 is arranged in the plane of the steel beam 4. The beam-column connectors are respectively used to connect the steel beam 4 with the front support column 6 and the rear support column 11. The front support column 6 and the front support bracket 7 are connected by bolts, and the rear support column 11 and the rear support bracket 10 are connected by bolts. The column root connector 15 for the support column is used to connect the column roots of the front support column 6 and the rear support column 11 during the disassembly and assembly of the photovoltaic support, so that the front support column 6 and the rear support column 11 are collinear and parallel to the steel beam 4, making the beam-column structure more compact and the bottom flat, facilitating handling and storage. The front support bracket 7 and the rear support bracket 10 are connected to the base 8, and the towing rings 9 are arranged at both ends of the base 8. The flat laying connector 13 is connected to the steel beam 4.

[0030] The bracing 14 uses a turnbuckle bolt, which should be installed after the purlin 3 is installed. When the bolt is tightened, the purlin 3 is under pressure, and at this time the purlin 3 is a beam-column member under combined compression and bending. The steel beam 4, the purlin 3 and the bracing 14 together form a planar structural system, thus providing sufficient in-plane stiffness for the photovoltaic cell module 1 and preventing the photovoltaic cell module 1 from being stressed due to planar distortion during handling.

[0031] The inclination angle of the rear support column 11 is comprehensively determined according to the inclination angle of the steel beam 4, the wind load value and the self-weight of the photovoltaic cell module 1. The included angle between the rear support column 11 and the steel beam 4 is 90°. The inclined arrangement of the rear support column 11 makes it more directly stressed when subjected to wind suction, changing from shear stress in the vertical arrangement to approximately axial tension, effectively reducing the in-plane horizontal displacement of the photovoltaic support under the most unfavorable combination and better protecting the photovoltaic cell module 1. Both the front support bracket 7 and the rear support bracket 10 are provided with adjustment bolt holes. Two bolts are provided at the lower part of each front support column 6, and one bolt is provided at the lower part of each rear support column 11, which serve as the fixed support and hinge support of the front support column 6 and the rear support column 11 respectively. Two bolts are provided for the front support column 6, which can be arranged in any two consecutive bolt holes of the front support bracket 7; one bolt is provided for the rear support column 11, which can be arranged in any bolt hole of the rear support bracket 10; so as to meet the requirement of adjusting the angle of the photovoltaic support according to the best sunshine angle in different regions and adjusting the height of the photovoltaic support according to the high water level in different regions.

[0032] The base 8 is selected from steel pipes or reinforced concrete materials that meet the requirements after inspection, and sufficient stiffness should be ensured to meet the flatness requirement; the end section of the base 8 is outwards inclined or the end is bent upwards. When the end is bent upwards, the overall dragging resistance can be reduced when there are terrain changes in the site, better adapting to complex sites. The towing rings 9 are arranged at the ends of the base 8, and the number of towing rings 9 in each detachable unit is not less than 4, which serve as the stress points for overall dragging and hoisting and are also convenient for fine adjustment of the target position.

[0033] The horizontal connecting piece 13 can be used when there is a strong wind warning. After removing the bolts of the rear strut 11, the steel beam 4 is directly connected to the rear support 10, reducing the inclination angle of the battery module, reducing the wind load to a certain extent, and being beneficial to the anti-overturning, anti-sliding and uplift stability of the overall structure. At the same time, the horizontal connecting piece 13 can also be used as a step in disassembling and assembling the photovoltaic bracket. First, remove the bolts of the rear strut 11, use the horizontal connecting piece 13 to place the steel beam 4 horizontally, the rear strut 11 is no longer stressed, and then remove the bolts of the front strut 6, saving the manpower and material resources for disassembling and assembling the photovoltaic bracket.
