[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0036] The core of the present application is to provide a photovoltaic double-column support, which can adopt standard modular production inclined support components and adapt to the installation of different mountain slopes.

[0037] Another core of the present application is to provide a mountain photovoltaic power station comprising the above-mentioned photovoltaic double-column support.

[0038] It should be noted that in the present embodiment, the directions or positional relationships indicated by "up", "down", "front", "rear" and the like are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0039] Please refer to Figure 1 The present application provides a photovoltaic double-column support, comprising: a front column 1, a rear column 2, an inclined beam 3, a front inclined support 4 and a rear inclined support.

[0040] The front column 1 and the rear column 2 are respectively vertically arranged on the ground along the direction from low to high of the mountain slope.

[0041] The inclined beam 3 is arranged between the top ends of the front column 1 and the rear column 2.

[0042] The front inclined support 4 is arranged between the inclined beam 3 and the front column 1.

[0043] The rear inclined support is arranged between the inclined beam 3 and the rear column 2, and the rear inclined support comprises a first standard piece 5 and a second standard piece 6, which are connected back to back along the length direction by a plurality of adjustable bolts 7 to form a rear inclined support with adjustable length.

[0044] It should be noted that the front column 1 and the rear column 2 are respectively vertically inserted on the ground, the inclined beam 3 is arranged between the top ends of the front column 1 and the rear column 2, the front column 1 and the rear column 2 play a role in supporting the inclined beam 3, and the inclined beam 3 is used for mounting the photovoltaic module. Among them, on the mountain, the front column 1 is lower than the rear column 2, the front inclined brace 4 is arranged between the inclined beam 3 and the front column 1, and plays a role in enhancing the rigidity and anti-seismic capacity of the support structure, and the rear inclined brace is arranged between the inclined beam 3 and the rear column 2, and also plays a role in enhancing the rigidity and anti-seismic capacity of the support structure. Obviously, the length of the front inclined brace 4 will not change with the change of the mountain slope, but the length of the rear inclined brace will be shortened with the increase of the mountain slope, and will be increased with the decrease of the mountain slope.

[0045] The first standard part 5 and the second standard part 6 are arranged back to back, and the two back surfaces abutting each other are provided with a plurality of bolt holes 8 for mounting the bolts 7 along the length direction, so that the first standard part 5 and the second standard part 6 can be connected together back to back by a plurality of bolts 7 to form the rear inclined brace. It is not difficult to understand that the bolts 7 have a detachable feature, so the relative position of the first standard part 5 and the second standard part 6 can be adjusted by adjusting the mounting position of the bolts 7, and then the length adjustment of the rear inclined brace is realized. Therefore, the first standard part 5 and the second standard part 6 can be produced by standard modularization, and then the rear inclined brace is realized by standard modularization. On the construction site, the relative position of the first standard part 5 and the second standard part 6 can be adjusted according to different mountain slopes, and then the installation of the rear inclined brace suitable for different mountain slopes is realized.

[0046] Considering the specific standard length of the first standard part 5 and the second standard part 6, on the basis of the above embodiment, the connection between the top end of the rear inclined brace and the inclined beam 3 is the first connection point, and the connection between the bottom end of the rear inclined brace and the rear column 2 is the second connection point.

[0047] The length of the second standard part 6 is the straight line distance between the first connection point and the second connection point when the mountain slope is the maximum slope; the length of the first standard part 5 is the difference between the straight line distance between the first connection point and the second connection point when the mountain slope is the minimum slope and the length of the second standard part 6, plus a certain lap length.

[0048] With Figure 7 and Figure 8The sizes of the parts shown are illustrative. When the maximum slope of the mountain is α = 30°, the straight-line length between the first connecting point and the second connecting point is 1942 mm, and the length of the second standard part 6 is 1942 mm. Thus, the second standard part 6 can be directly used. When the minimum slope of the mountain is α = 0°, the straight-line length between the first connecting point and the second connecting point is 3212 mm, and the difference between the straight-line length and the length of the second standard part 6 is equal to 1270 mm. On this basis, the lap length of 150 mm is added, the length of the first standard part 5 is 1420 mm. It should be noted that the lap length is the length of the overlapping region of the first standard part 5 and the second standard part 6 when the slope of the mountain is the minimum. When 0° < the slope of the mountain α < 30°, only the relative positions of the first standard part 5 and the second standard part 6 need to be adjusted. That is, if the slope of the mountain increases, the length of the required rear diagonal brace needs to be shortened, the first standard part 5 and the second standard part 6 are moved towards each other, the length of the overlapping region of the two parts is increased, and thus the length of the rear diagonal brace is shortened. Conversely, if the slope of the mountain decreases, the length of the required rear diagonal brace needs to be increased, the first standard part 5 and the second standard part 6 are moved away from each other, the length of the overlapping region of the two parts is interrupted, and thus the length of the rear diagonal brace is increased. It should be noted that the overlapping region of the first standard part 5 and the second standard part 6 is fastened by at least three bolts 7.

[0049] Therefore, by setting the lengths of the first standard part 5 and the second standard part 6 according to the above standard, regardless of the degree of the slope of the mountain, the rear diagonal brace of the full-mountain-area double-column support can be installed to adapt to the more complex and more detailed mountain slope.

[0050] Preferably, when the slope of the mountain is not the maximum, the second standard part 6 and the first standard part 5 are arranged in the direction from top to bottom. Thus, during installation, the top end of the second standard part 6 can be installed on the inclined beam 3 in advance. When the maximum slope of the mountain is installed, the installation of the first standard part 5 can be directly skipped, and the bottom end of the second standard part 6 can be installed on the rear column 2. When the remaining slopes of the mountain are installed, the installation position of the first standard part 5 relative to the second standard part 6 can be adjusted according to the change in the slope of the mountain. Therefore, by arranging the two standard parts in the above manner, the length of the rear diagonal brace can be adjusted according to different slopes of the mountain.

[0051] Taking into account the specific structure of the first standard part 5 and the second standard part 6, on the basis of the above embodiments, please refer to Figure 2 , Figure 3 and Figure 5 , the first standard part 5 and the second standard part 6 are both C-shaped steel, the bottom plates of the two are arranged back to back and are both provided with a plurality of bolt holes 8 for installing the bolts 7 along the length direction.

[0052] It can be understood that the C-shaped steel has the characteristics of light weight and strong carrying capacity, and the first standard piece 5 and the second standard piece 6 are both made of C-shaped steel, which can reduce the rear support and improve the carrying capacity of the rear support, thereby improving the safety and stability of the whole support. And the C-shaped steel is generally composed of a bottom plate and two side plates vertically arranged on both sides of the bottom plate, and a plurality of bolt holes 8 are arranged on the bottom plate of the first standard piece 5 and the second standard piece 6 along the length direction, which facilitates the back-to-back bolt 7 connection of the two standard pieces.

[0053] Preferably, referring to Figure 3 , the cross sections of the first standard piece 5 and the second standard piece 6 are the same, which facilitates the alignment and stamping of the bolt holes 8 of the two standard pieces during processing and production, not only facilitating the processing and production, but also facilitating the bolt 7 connection of the overlapping area of the two standard pieces.

[0054] To further optimize the fastening mode between the first standard piece 5 and the second standard piece 6, on the basis of the above embodiment, please refer to Figure 2 and Figure 4 , the two side plates on the same side of the first standard piece 5 and the second standard piece 6 are buckled together by the clamping piece 9. Thus, the first standard piece 5 and the second standard piece 6 can be firmly connected.

[0055] Preferably, the clamping piece 9 buckles the overlapping two side plates of the first standard piece 5 and the second standard piece 6, so as to effectively ensure the stability of the overlapping part (i.e. the overlapping part) of the two standard pieces, and the clamping piece 9 can be produced in a standard modular way, and the size of the clamping piece 9 is simplified. Since different rear diagonal bracing lengths correspond to different overlapping lengths, the number of clamping pieces 9 can be adjusted according to different overlapping lengths.

[0056] Considering the specific arrangement of the clamping piece 9, on the basis of the above embodiment, please refer to Figure 4 and Figure 6 , the clamping piece 9 includes a middle plate 91, two right angle plates 92 and two clamping plates 93, the first plate bodies of the two right angle plates 92 are vertically arranged on both sides of the middle plate 91, and the two clamping plates 93 are vertically arranged on the second plate bodies of the two right angle plates 92 and both face the middle plate 91.

[0057] It should be noted that the two side plates of the C-shaped steel are vertically provided with buckles away from the bottom plate, and the two buckles are oppositely arranged. The clamping piece 9 with the above structure, the clamping plate 93 and the right angle plate 92 form a clamping groove, and the clamping groove is slidably connected with the buckles of the C-shaped steel. In this way, during on-site construction, before the first standard piece 5 and the second standard piece 6 are installed back to back, the middle plate 91 on one side of the clamping piece 9 can be pre-attached to the bottom plate of the first standard piece 5 to slide, so that the buckle on the upper side of the first standard piece 5 slides into the clamping groove on one side of the clamping piece 9 to pre-complete the installation of the clamping piece 9 and the first standard piece 5, then the side plate and the buckle on the upper side of the second standard piece 6 slide along the middle plate 91 and the clamping groove on the other side of the clamping piece 9 to the appropriate length position to complete the installation of the clamping piece 9 and the second standard piece 6, and then the buckling of the two standard pieces is completed.

[0058] Therefore, the clamping piece 9 with the above structure buckles the two standard pieces, which not only ensures the firm connection of the two standard pieces, but also improves the convenience of installation of the two standard pieces.
