Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and more specifically, to a photovoltaic support structure. Background Technology

[0002] Photovoltaic panels are devices that directly generate electricity from solar energy. They are primarily made of silicon semiconductor materials and convert light energy into electrical energy, facilitating the collection and utilization of clean energy. Photovoltaic power generation is not limited by resource distribution and can be applied in various complex terrains such as wastelands, deserts, and hills. With the development and promotion of environmentally friendly energy both domestically and internationally, photovoltaic power generation is being used more and more widely. Currently, in mountainous areas, installation involves inserting poles into the ground for fixation. The depth to which the poles are driven into the ground directly determines the stability of the support structure; different depths will cause instability in the overall support system.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-7 As shown, a photovoltaic support includes a base 1, vertical rods 2, longitudinal rods 6, and horizontal rods 7. The base 1 can be constructed of concrete according to the terrain, and the upper surface of the base 1 must be level. Several mounting screws 9 are pre-installed on the upper end of the base 1, and the mounting screws 9 are vertically arranged. A connecting seat 5 is installed on the upper end of the base 1. The connecting seat 5 includes a fixing plate 10 and a fixing base 13 connected to the upper part of the fixing plate 10. The fixing base 13 has a hollow structure. A fixing hole 11 is provided on the fixing plate 10, through which the mounting screws 9 pass. At least two fixing nuts 12 are threadedly connected to the portion of the mounting screws 9 passing through the fixing hole 11. The fixing plate 10 is fixed to the base 1 by the cooperation of the fixing nuts 12 and the mounting screws 9.

[0024] like Figure 4 As shown, the vertical bar 2, the longitudinal bar 6, and the horizontal bar 7 have roughly the same structure, each including a base plate 18 and side plates 19 connected to both sides of the base plate 18. The side plates 19 are perpendicular to the base plate 18. Several fixing holes 21 are provided on the base plate 18. The fixing holes 21 are oval holes, which allow for adjustment when fixing.

[0025] like Figure 3 As shown, a reinforcing plate 14 is connected to the side of the fixing base 13. The lower end face of the reinforcing plate 14 is connected to the upper end face of the fixing plate 10. The reinforcing plate 14 strengthens the connection between the fixing base 13 and the fixing plate 10.

[0026] like Figures 1-3As shown, the bases 1 are arranged in an array. The lower ends of the vertical rods 2 are installed in the connecting seats 5. Specifically, the lower ends of the vertical rods 2 are inserted into the fixing seats 13. Fixing bolts 15 are installed on the fixing seats 13, passing through fixing holes 21 on the vertical rods 2. The fixing bolts 15 secure the vertical rods 2 and the fixing seats 13. A tightening screw 16 is also threaded onto the side of the fixing seats 13. The inner end of the tightening screw 16 abuts against the side plate 19 of the vertical rod 2, serving as an auxiliary fixing mechanism. The upper ends of the vertical rods 2 in the same column are connected to longitudinal rods 6 via connecting pieces 4. The connecting pieces 4 are fixed to the lower ends of the longitudinal rods 6 via fixing bolts 31, and the upper ends of the vertical rods 2 are connected to the connecting pieces 4 via fixing bolts. Several horizontal rods 7 are installed on the upper part of the longitudinal rods 6 via fixing bolts. The horizontal rods 7 are perpendicular to the longitudinal rods 6. Photovoltaic panels 32 are installed on the crossbar 7 via a central pressure block and an edge pressure block. The central pressure block is located between two adjacent photovoltaic panels 32 in the same column, and the edge pressure block is located on the outside of the photovoltaic panel 32 at the edge.

[0027] The fixing bolt 15 passes through different fixing holes 21 on the vertical rod 2 to fix the vertical rod 2, and the height of the upper end of the vertical rod 2 can be adjusted. According to the actual installation needs, the height of the upper end of each vertical rod 2 in the same row is adjusted, so that the height difference of the upper end of each vertical rod 2 changes, thereby changing the tilt angle of the longitudinal rod 6 installed on the upper end of the vertical rod 2, and thus changing the installation angle of the photovoltaic panel 32.

[0028] like Figure 4 As shown, the crossbar 7 also includes a flange 17, which is located at the upper end of the side plate 19 and bent towards the inside of the side plate 19, forming a gap 20 between the flange 17 and the side plate 19. The center pressure block and the side pressure block are mounted on the crossbar 7 via the cooperation of a wing nut 25 and a fixing screw 26. The wing nut 25 is located below the flange 17, as shown... Figure 7 As shown, the wing nut 25 includes a nut plate 29 with a limiting groove 30. The fixing screw 26 passes through the middle pressure block or the side pressure block and is screwed into the wing nut 25. During the tightening of the fixing screw 26, the lower end of the folded edge 17 is inserted into the limiting groove 30, thereby restricting the rotation of the nut plate 29 after the fixing is completed, ensuring the firmness of the fixing.

[0029] like Figure 4 As shown, the edge clamping block includes a mounting plate 22. A fastener 23 is connected to one side of the mounting plate 22 near the photovoltaic panel 32. The fastener 23 can fit against the outer side and upper surface of the photovoltaic panel 32. An abutment plate 24 is connected to the other side of the mounting plate 22. Figure 6 As shown, the intermediate pressure block includes a second mounting plate 27, and fasteners 28 are connected to both sides of the second mounting plate 27. The fasteners 28 can fit against the side and top surface of the photovoltaic panel 32. Both the first mounting plate 22 and the second mounting plate 27 have through holes for the fixing screws 26 to pass through.

[0030] like Figure 5 As shown, a support rod 3 is connected between the side of the vertical rod 2 and the lower end of the longitudinal rod 6 to enhance the stability. The support rod 3 is connected to the vertical rod 2 and the longitudinal rod 6 by a connector 4. The connector 4 is installed on the longitudinal rod 6 and the vertical rod 2 by fixing bolts passing through fixing holes 21. The two ends of the support rod 3 are then connected to the connector 4 by fixing bolts.

[0031] A reinforcing rod 8 is installed between two adjacent vertical rods 2 in the same row, with the two ends of the reinforcing rod 8 located at different heights to enhance the stability.

[0032] like Figure 8 As shown, auxiliary poles 33 can be installed on the vertical poles 2 in the same row using fixing bolts. The structure of the auxiliary poles 33 is roughly the same as that of the vertical poles 2. Auxiliary equipment such as combiner boxes 34 can be installed on the auxiliary poles 33. The auxiliary equipment of the photovoltaic system requires ventilation and heat dissipation, and must also avoid water ingress and direct sunlight. Usually, it is placed in a separately made rainproof and ventilated electrical cabinet or in a remote control room, which requires additional costs. By installing them on the auxiliary poles 33, using the photovoltaic panels 32 for waterproofing and avoiding direct sunlight, and providing a good ventilation environment for heat dissipation, the normal use of the auxiliary equipment can be met without increasing the cost.

[0033] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
