[0006] The counterweight is located on the ground.

[0007] A first support rod extends in a direction perpendicular to the ground, and one end of the first support rod is connected to the counterweight.

The first connecting end of the connecting frame is connected to a second position of the support frame, and the third connecting end of the connecting frame is connected to a third position of the support frame. The first position, the second position, and the third position are arranged sequentially along the length or width direction of the support frame. The support frame is used to support photovoltaic modules.

[0010] In one exemplary embodiment of this disclosure, the counterweight includes a first counterweight, a second counterweight, and a connector connecting the first counterweight and the second counterweight. The first support rod is connected to the first counterweight, and the second support rod is connected to the second counterweight.

[0011] In one exemplary embodiment of this disclosure, both the first and second ballast components include a ballast box and filler material filling the ballast box, wherein the filler material is cement or concrete.

[0012] In one exemplary embodiment of this disclosure, the end of the first support rod away from the counterweight is hinged to a first position of the support frame.

[0013] In one exemplary embodiment of this disclosure, one end of the second support rod is hinged to the second counterweight, and the other end is hinged to the second connecting end.

[0014] In an exemplary embodiment of this disclosure, the connecting frame is an arc-shaped connecting rod, the center of the arc of which is located on the side of the arc-shaped connecting rod away from the second support rod; the first connecting end is the end of the arc-shaped connecting rod closer to the first support rod, and the third connecting end is the end of the arc-shaped connecting rod away from the first support rod; the second connecting end is located between the first connecting end and the third connecting end.

[0027] This disclosure provides a counterweight photovoltaic support, such as Figure 1 As shown, the photovoltaic support can include a counterweight 1, a first support rod 2, a support member 3, and a support frame 4, wherein:

[0028] The counterweight 1 is located on the ground;

[0029] The first support rod 2 extends in a direction perpendicular to the ground, and one end of the first support rod 2 is connected to the counterweight 1;

[0030] The support member 3 includes a second support rod 31 and a connecting frame 32. The connecting frame 32 includes a first connecting end, a second connecting end and a third connecting end that are distributed sequentially and are not collinear. One end of the second support rod 31 is connected to the end of the counterweight 1 that is away from the first support rod 2, and the other end is connected to the second connecting end of the connecting frame 32.

[0031] The support frame 4 is located on the side of the first support rod 2 and the support member 3 away from the counterweight 1. The end of the first support rod 2 away from the counterweight 1 is connected to the first position 41 of the support frame 4. The first connecting end of the connecting frame 32 is connected to the second position 42 of the support frame 4. The third connecting end of the connecting frame 32 is connected to the third position 43 of the support frame 4. The first position 41, the second position 42 and the third position 43 are arranged sequentially along the length or width direction of the support frame 4.

[0032] The gravity-type photovoltaic support system disclosed herein eliminates the need for large-scale excavation and other foundation construction during installation, making it environmentally friendly. Specifically, the gravity-type photovoltaic support system uses a gravity component 1 instead of traditional pile foundations. The gravity component 1's own weight replaces the traditional pile foundation, avoiding excavation, pile driving, and fixing processes, thus minimizing environmental damage. It also saves time required for excavation, pile driving, and fixing, helping to shorten the construction cycle and improve construction efficiency. Furthermore, by connecting the first support rod 2 and the support member 3 to the support frame 4, the support frame 4 is supported by the first support rod 2 and the support member 3, ensuring a certain height between the support frame 4 and the ground. This allows the photovoltaic modules 5 on the support frame 4 to absorb light energy without obstruction, thereby improving power generation efficiency.

[0033] The following is a detailed description of each part and specific details of the counterweight photovoltaic support disclosed herein:

[0034] The counterweight 1 can be located on the ground, for example, it can be placed directly on the ground. The counterweight 1 has a large weight. For example, the weight of the counterweight 1 can be much greater than the total weight of the first support rod 2, support member 3, support frame 4 and photovoltaic module 5 to be installed on it. For example, the weight of the counterweight 1 can be 8 tons to 12 tons.

[0035] In one exemplary embodiment of this disclosure, the ballast section 1 may include multiple rows of spaced-apart ballast structures. Each row of ballast structures may include multiple spaced-apart and connected ballast members. The first support rod 2, support member 3, support frame 4, and photovoltaic module 5 to be installed on the ballast section can be simultaneously fixed by the multiple interconnected ballast members. For example, in the same ballast structure, adjacent ballast members can be connected by horizontal connecting rods to ensure the horizontal stability of each ballast member and avoid displacement. At the same time, the ballast members in adjacent ballast structures can also be connected by horizontal connecting rods respectively, thereby forming multiple rows of stable structures, which can improve the structural stability and overall wind resistance of the ballast section 1.

[0036] For example, the counterweight 1 may include at least a first counterweight 11 and a second counterweight 12. The first counterweight 11 and the second counterweight 12 may be connected together by a connector 13. The connector 13 may be rod-shaped, with one end of the connector 13 hinged to the first counterweight 11 and the other end hinged to the second counterweight 12.

[0037] In one exemplary embodiment of this disclosure, both the first counterweight 11 and the second counterweight 12 may include a counterweight box 101 and a filler 102. The counterweight box 101 may be made of metal, alloy, or stainless steel, etc., and the filler 102 may fill the counterweight box 101 completely. The filler 102 has a relatively large weight. For example, the filler 102 may be made of cement or concrete, etc.

[0038] The first support rod 2 may be rod-shaped, and its cross-section may be circular, elliptical, rectangular, polygonal, or irregular in shape, without special limitation. The material of the first support rod 2 may be metal, alloy, or stainless steel, etc. The first support rod 2 may extend in a direction perpendicular to the ground. One end of the first support rod 2 is connected to the counterweight 1, for example, the first support rod 2 may be connected to the first counterweight 11. For example, the first support rod 2 may be welded, snap-fitted, or bolted to the counterweight box 101 of the first counterweight 11; of course, the first support rod 2 may also be bolted to the counterweight box 101 first, and then reinforced by welding.

[0039] The support member 3 may include a second support rod 31 and a connecting frame 32. The second support rod 31 may be rod-shaped, and its cross-section may be circular, elliptical, rectangular, polygonal, or irregular in shape, without special limitation. The material of the second support rod 31 may be metal, alloy, or stainless steel, etc. The second support rod 31 is inclined relative to the ground, and also inclined relative to the first support rod 2. For example, the second support rod 31 is inclined toward the side closer to the first support rod 2.

[0040] The connecting frame 32 may include a first connecting end, a second connecting end, and a third connecting end that are sequentially distributed and not collinear. For example, the connecting frame 32 may be an arc-shaped connecting rod, the center of which may be located on the side of the arc-shaped connecting rod away from the second support rod 31; the first connecting end may be the end of the arc-shaped connecting rod closer to the first support rod 2, and the third connecting end may be the end of the arc-shaped connecting rod away from the first support rod 2; the second connecting end may be located between the first connecting end and the third connecting end. Alternatively, the connecting frame 32 may include a first connecting segment, a second connecting segment, and a third connecting segment that are sequentially connected and not collinear between any two of them, the first connecting segment and the third connecting segment being located on the same side of the second connecting segment, the first connecting segment extending away from the third connecting segment, and the third connecting segment extending away from the first connecting segment, and the first connecting segment and the third connecting segment being symmetrically distributed; the first connecting end may be the end of the first connecting segment away from the second connecting segment, the second connecting end may be the center part of the second connecting segment in the length direction, and the third connecting end may be the end of the third connecting segment away from the second connecting segment.

[0041] In one exemplary embodiment of this disclosure, one end of the second support rod 31 can be connected to the end of the counterweight 1 that is away from the first support rod 2, and the other end can be connected to the second connecting end of the connecting frame 32. For example, when the counterweight 1 includes a first counterweight 11 and a second counterweight 12 and the first support rod 2 is connected to the first counterweight 11, one end of the second support rod 31 can be hinged to the second counterweight 12, and the other end can be hinged to the second connecting end in the connecting frame 32.

[0042] For example, the counterweight photovoltaic support disclosed herein may further include a first connecting ear 6. The first connecting ear 6 may include a first fixing part and a first connecting part. Both the first fixing part and the first connecting part may be plate-shaped or block-shaped. The first fixing part may include a first surface and a second surface that are parallel to each other. Both the first surface and the second surface may be planar. The first surface contacts and connects with the top surface (i.e., the surface away from the ground) of the counterweight box 101 in the second counterweight part 1. One end of the first connecting part contacts and connects with the second surface and extends to the side away from the top surface of the counterweight box 101. The first connecting part is provided with a first connecting hole that penetrates the first connecting part in a direction parallel to the second surface. The end of the second support rod 31 near the second counterweight part 1 is provided with a first mounting hole. A pin can be used to pass through the first mounting hole and the first connecting hole in sequence to connect the second support rod 31 to the first connecting part.

[0043] The support frame 4 can be located on the side of the first support rod 2 and support member 3 away from the counterweight 1. The support frame 4 can be used to support the photovoltaic module 5, that is, the photovoltaic module 5 can be supported by the support frame 4 to realize photovoltaic power generation. The end of the first support rod 2 away from the counterweight 1 is connected to the first position 41 of the support frame 4, the first connecting end of the connecting frame 32 is connected to the second position 42 of the support frame 4, and the third connecting end of the connecting frame 32 is connected to the third position 43 of the support frame 4. That is, the support frame 4 can be supported at three points by the first support rod 2 and support member 3 to ensure the stability of the support structure. In this process, the tilt angle of the support frame 4 can be accurately set by matching the dimensions of the first support rod 2, the second support rod 31 and the connecting frame 32.

[0044] In one exemplary embodiment of this disclosure, the length of the first support rod 2 may be less than the length of the support member 3, making the side of the support frame 4 closer to the support member 3 relatively higher, while the side of the support frame 4 closer to the first support rod 2 relatively lower. This results in the support frame 4, supported by the first support rod 2 and the support member 3, presenting a preset angle. This preset angle can be set according to the terrain and lighting conditions, and is not specifically limited here. For example, the preset angle can be 10° to 45°, such as 10°, 20°, 30°, 40°, or 45°. Of course, the preset angle can also be other values, specifically set according to local sunlight conditions, and will not be listed here.

[0045] It should be noted that the first position 41, the second position 42, and the third position 43 can be arranged sequentially along the length or width direction of the support frame 4. In some embodiments of this disclosure, the second position 42 is the middle position along the length direction of the support frame 4, or the second position 42 is the middle position along the width direction of the support frame 4. The distance between the first position 41 and the second position 42 can be greater than the distance between the third position 43 and the second position 42.

[0046] In an exemplary embodiment of this disclosure, the end of the first support rod 2 that is away from the counterweight 1 can be hinged to the first position 41 of the support frame 4. During the installation of the support frame 4, the support frame 4 can be connected to the first support rod 2 first. At this time, the support frame 4 can rotate up and down relative to the first support rod 2 so as to adjust the tilt angle of the support frame 4 relative to the ground.

[0047] For example, the counterweight photovoltaic support disclosed herein may further include a second connecting ear 7. The second connecting ear 7 may include a second fixing part and a second connecting part. Both the second fixing part and the second connecting part may be plate-shaped or block-shaped. The second fixing part may include two parallel surfaces, both of which may be planar. One surface is connected to the surface of the support frame 4 at the first position 41 near the first support rod 2. One end of the second connecting part is in contact with the surface of the second fixing part near the first support rod 2 (i.e., the other surface) and extends towards the side near the first support rod 2. The second connecting part is provided with a second connecting hole that penetrates the second connecting part along its thickness. The end of the first support rod 2 near the support frame 4 is provided with a second mounting hole. A pin can be used to pass through the second mounting hole and the second connecting hole in sequence to connect the first support rod 2 to the second connecting part.

[0048] In one exemplary embodiment of this disclosure, the first connecting end and the third connecting end of the connecting frame 32 are detachably connected to the support frame 4. In other embodiments of this disclosure, the first connecting end and the third connecting end can be fixedly connected to the support frame 4 based on the detachable connection, for example, by welding.

[0049] In one exemplary embodiment of this disclosure, after adjusting the tilt angle of the support frame 4, the second connecting end of the connecting frame 32 can be fixedly connected to the second support rod 31, and the second support rod 31 can be fixedly connected to the second counterweight 12 to ensure the stability of the entire system.

[0050] This disclosure also provides a photovoltaic system, which may include the counterweight photovoltaic support frame and multiple photovoltaic modules 5 as described in any of the above embodiments. The multiple photovoltaic modules 5 may be distributed in an array on the support frame 4. The structure and beneficial effects of the counterweight photovoltaic support frame have been described in detail in the embodiments of the counterweight photovoltaic support frame, and therefore will not be described in detail here.

[0051] In one exemplary embodiment of this disclosure, there may be multiple counterweight photovoltaic supports, which may be distributed at intervals. Multiple counterweight photovoltaic supports can simultaneously support a large number of photovoltaic modules 5, so as to expand the distribution area of ​​photovoltaic modules 5 according to the actual installation site, thereby increasing the power generation.

[0052] It should be noted that the counterweight parts 1 in the multiple counterweight photovoltaic brackets can be connected separately to improve the structural reliability of the photovoltaic system.

[0053] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
