[0028] Referring to Figures 1-5 , the support structure of the photovoltaic module and the head 200 of the column provided by an embodiment of the application are used to be partially arranged in the first through hole 110 of the column 100, the head 200 includes a first side wall 220, a second side wall 240 and a rotating support 230, the two ends of the rotating support 230 along the second direction OY are connected with the first side wall 220 and the second side wall 240 respectively, the first side wall 220, the rotating support 230 and the second side wall 240 are used to enclose a second through hole 260, the first through hole 110 and the second through hole 260 both extend along the first direction OX, the main beam assembly 300 is arranged in the second through hole 260, and the rotating support 230 is used to support the main beam assembly 300 with different inclination angles.

[0029] In actual use, the head 200 can be used as a standard part, the main beam assembly 300 is arranged through the second through hole 260 of the head 200, and then the head 200 is partially arranged in the first through hole 110 of the column 100, so that the installation of the main beam assembly 300 is realized; at the same time, since the rotating support 230 is used to support the main beam assembly 300 with different inclination angles, the head 200 as a standard part can realize the installation of the main beam assembly 300 with different inclination angles and the column 100, and the structure is simple and the installation is convenient.

[0030] In some embodiments, the rotating support 230 is a connecting shaft, and the two ends of the connecting shaft along the second direction OY are connected with the first side wall 220 and the second side wall 240 respectively.

[0031] In the embodiment, a connecting shaft is connected between the first side wall 220 close to one end of the bottom and the second side wall 240 close to one end of the bottom, and when the main beam assembly 300 passes through the second through hole 260, the connecting shaft is used to support the main beam assembly 300, so that the main beam assembly 300 can rotate around the connecting shaft, thereby realizing the installation of the main beam assembly 300 with different inclination angles.

[0032] In some other embodiments, the rotating support 230 is a bottom wall, and the two ends of the bottom wall along the second direction OY are connected with the first side wall 220 and the second side wall 240 through rotating shafts 231 respectively.

[0033] In the embodiment, the bottom wall is rotatably connected with the first side wall 220 and the second side wall 240 respectively, so that the inclination angle of the bottom wall is adapted to the inclination angle of the main beam assembly 300.

[0034] In some embodiments, the middle part of the rotating support 230 along the first direction OX is connected with the middle part of the first side wall 220 along the first direction OX and the middle part of the second side wall 240 along the first direction OX respectively.

[0035] In the embodiment, the middle part of the rotating support 230 along the first direction OX is rotatably connected with the middle part of the first side wall 220 along the first direction OX and the middle part of the second side wall 240 along the first direction OX respectively, which facilitates reducing the opening size of the first through hole 110.

[0036] Specifically, when the rotating support 230 is a connecting shaft, the middle part of the rotating support 230 along the first direction OX is fixedly or rotatably connected with the middle part of the first side wall 220 along the first direction OX and the middle part of the second side wall 240 along the first direction OX respectively. When the rotating support 230 is a bottom wall, the middle part of the rotating support 230 along the first direction OX is rotatably connected with the middle part of the first side wall 220 along the first direction OX and the middle part of the second side wall 240 along the first direction OX through the rotating shafts 231 respectively.

[0037] In some embodiments, the column head 200 comprises a top cover 210, which is arranged at the end of the first side wall 220 and the second side wall 240 away from the bottom wall, and the top cover 210 is used to be erected on the top of the column 100.

[0038] In the embodiment, in combination with Figure 4 , the first through hole 110 is arranged on the column 100, the top of the first through hole 110 extends to the outside of the column 100, and the column head 200 is directly placed in the first through hole 110 from top to bottom, so that the top cover 210 is erected on the top of the first through hole 110, and the top cover 210 is used to support the column head 200 to prevent the column head 200 from falling.

[0039] Further, the top cover 210 has a size in each direction that is greater than or equal to a size of the corresponding direction of the column 100.

[0040] In some embodiments, the size of the top cover 210 in each direction is equal to the size of the corresponding direction of the column 100, or the size of the top cover 210 in each direction is greater than the size of the corresponding direction of the column 100, so that the top cover 210 can shield the first through hole 110 to prevent rainwater from entering the first through hole 110.

[0041] Specifically, the column 100 can be a solid structure or a hollow structure. When the column 100 is a solid structure, the column 100 is provided with the first through hole 110 extending along the first direction OX. When the column 100 is a hollow structure, the column 100 includes the first side plate 120, the second side plate 130, the third side plate 140, and the fourth side plate 150 connected in sequence. The first side plate 120 and the third side plate 140 are spaced apart along the second direction OY. The second side plate 130 and the fourth side plate 150 are respectively provided with through holes arranged oppositely, so that the top part forms the first through hole 110 extending along the first direction OX.

[0042] In some embodiments, the first side wall 220 and the second side wall 240 are respectively provided with at least two corresponding threaded holes 221.

[0043] In actual installation, the column head 200 is prefabricated as a standard part. During installation at the construction site, according to the inclination angle of the main beam assembly 300, threaded holes corresponding to the position of the column head 200 are respectively formed in the column 100 and the main beam assembly 300. During installation, the bolts are sequentially threaded through the column 100, the column head 200, and the main beam assembly 300 to realize the fixation of the three. That is, the present application does not need to use welding, has a short construction period, and has a small construction technical difficulty.

[0044] In some embodiments, the first side wall 220 and the second side wall 240 are respectively provided with stiffening ribs 250 extending along the second direction OY and away from the side of the first through hole 110. One end of the stiffening rib 250 along the height direction is connected with the top cover 210.

[0045] In the embodiment, when installed, the first sidewall 220 and the second sidewall 240 of the column head 200 are installed in the second through hole 260 of the stand column 100, that is, the stiffening rib 250 is also located in the second through hole 260, and the stiffening rib 250 is located between the sidewall of the column head 200 along the second direction and the side plate of the stand column 100 along the second direction, which can limit the column head 200 along the second direction OY and prevent the column head 200 from moving the main beam assembly 300 along the second direction OY. In addition, the stiffening rib 250 is also used to prevent the second side plate and the fourth side plate of the stand column 100 from being deformed due to the locking force of the bolt when the stand column 100 and the column head 200 are bolted.

[0046] An embodiment of the present application discloses a support structure of a photovoltaic module and a column head 200 thereof. The support structure comprises a stand column 100, a main beam assembly 300, a bolt and the column head 200. The top of the stand column 100 is provided with a first through hole 110 extending along a first direction. The column head 200 is partially arranged in the first through hole 110. The main beam assembly 300 is arranged on a rotating support 230. The bolt passes through the stand column 100, the column head 200 and the main beam assembly 300 along a second direction in sequence and locks the stand column 100, the column head 200 and the main beam assembly 300.

[0047] In the embodiment, the column head 200 can be used as a standard part. The main beam assembly 300 passes through the second through hole 260 on the column head 200, and then the column head 200 is partially arranged in the first through hole 110 of the stand column 100, so that the installation of the main beam assembly 300 is realized. At the same time, since the rotating support 230 is used to support the main beam assembly 300 with different inclination angles, the column head 200 as a standard part can realize the installation of the main beam assembly 300 with no inclination angle and the stand column 100, and the structure is simple and the installation is convenient. In addition, the bolt passes through the stand column 100, the column head 200 and the main beam assembly 300 along the second direction in sequence and locks the stand column 100, the column head 200 and the main beam assembly 300, that is, welding is not needed, the construction period is short, and the construction technology is difficult.

[0048] In some embodiments, in combination with Figure 3 and Figure 5 , the connecting position of the rotating support 230 and the first sidewall 220 and the second sidewall 240 is higher than the bottom wall height of the first through hole 110.

[0049] The bottom wall of the first through hole 110 refers to the bottom wall height of the through hole on the second side plate 130 and the fourth side plate 150.

[0050] In the present embodiment, the connection position of the rotating support 230 with the first side wall 220 and the second side wall 240 is higher than the bottom wall height of the first through hole 110, i.e. when the main beam assembly 300 is tilted, the problem of the tilt angle limitation of the main beam assembly 300 caused by the interference between the bottom of the first through hole 110 and the lower end of the main beam assembly 300 can be prevented.

[0051] The technical features of the above-described embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features of the above-described embodiments are described, however, as long as the combination of the technical features does not result in contradictions, it shall be considered within the scope of the present disclosure.

[0052] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it shall not be understood as a limitation on the patent scope of the present application. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these shall be within the protection scope of the present application. Therefore, the patent protection scope of the present application shall be subject to the appended claims.
