[0002] With the development of photovoltaic power generation, many photovoltaic projects are built in mountainous areas with good light and heat conditions. Due to the undulating terrain in mountainous areas, the photovoltaic array needs to cross mountains or valleys. When the same array crosses a mountain or valley, the lengths of the columns on both sides often vary greatly, and a group of columns need to be added on the mountain or valley, which greatly increases the steel consumption of the photovoltaic project. In addition, it also increases the construction difficulty and prolongs the construction period, resulting in too high construction costs for the photovoltaic project, poor economy, and possibly deviating from the economic benefit analysis at the time of project establishment, leading to project losses.

[0010] Further, the flange of the C-shaped structure includes an upper flange and a lower flange, and the web, the upper flange, and the lower flange of the C-shaped structure all have purlin connection holes.
[0011] Furthermore, the aperture of the first connection hole is larger than that of the purlin connection hole.
[0012] Furthermore, the aperture of the first connection hole is 18 - 20 mm, and the aperture of the purlin connection hole is 10 - 12 mm.
[0013] Furthermore, the number of purlin connection holes at the web is ≥ the number of purlin connection holes at the lower flange > the number of purlin connection holes at the upper flange.

[0025] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings.
[0026] Embodiment 1
[0027] As shown in the Figures 1-3 accompanying drawings, the following technical solution is provided in this embodiment:
[0028] A mountain photovoltaic cross-slope / valley purlin connector includes: a first connector 1 and a second connector 2 that are mechanically connected to each other. Both the first connector 1 and the second connector 2 are of C-shaped structure. The web 3 and / or flange of the C-shaped structure have purlin connection holes. The first connector 1 and the second connector 2 are respectively connected to the purlins 8 on both sides of the mountain peak or valley through the purlin connection holes. A purlin connection bolt 6 passes through the purlin connection hole to fix the purlin to the photovoltaic purlin connection device.
[0029] Furthermore, the connection is a bolt connection. One end of the first connector 1 and the second connector 2 that are connected to each other both have first connection holes. A first connection bolt 7 passes through the first connection holes to fix the first connector and the second connector.
[0030] Furthermore, the center of the circle of the first connection hole is located on the center line of the web 3 of the C-shaped structure.
[0031] Furthermore, the flange of the C-shaped structure includes an upper flange 4 and a lower flange 5. The web 3, the upper flange 4, and the lower flange 5 of the C-shaped structure all have purlin connection holes.
[0032] Furthermore, the aperture of the first connection hole is larger than the aperture of the purlin connection hole.
[0033] In some preferred implementation schemes of this embodiment, the aperture of the first connection hole is 18 - 20 mm, and the matching high-strength bolt is M16 - M18, which can meet the requirements of 0.8 kN / m 2 wind pressure and 0.5 kN / m 2 snow pressure areas; the aperture of the purlin connection hole is 10 - 12 mm, and the matching high-strength bolt is M8 - M10.
[0034] Furthermore, the number of purlin connection holes at the web 3 ≥ the number of purlin connection holes at the lower flange 5 > the number of purlin connection holes at the upper flange 4.
[0035] Furthermore, the number of purlin connection holes at the lower flange 5 is 2 or 3, the number of purlin connection holes at the web 3 is 3, and the number of purlin connection holes at the upper flange 4 is 1.
[0036] Furthermore, both the first connector and the second connector are made of low-carbon steel and are hot-dip galvanized for anti-corrosion.
[0037] In some preferred embodiments of this embodiment, the first connecting member and the second connecting member are made of Q235B low-carbon steel, and the thickness of hot-dip galvanized anti-corrosion is not less than 85 μm.
[0038] Furthermore, the sizes of the first connecting member and the second connecting member both match the purlin 8.
[0039] In some preferred embodiments of this embodiment, the dimension of the web direction of the C-shaped structure of the first connecting member and the second connecting member is 15 mm larger than that of the web of the purlin, and the dimension of the flange direction is 15 mm larger than that of the flange of the purlin. The length is 260 mm, wherein the length of the web is 260 mm and the length of the flange is 140 mm. The thickness of the flange is 5 mm and the thickness of the web is 8 mm. That is, the length of the web is greater than the length of the flange. There is a part of the web where there are no flanges on both sides, just a flat steel plate. The first connection hole is set here, so that the first connecting member and the second connecting member do not need to be turned over during installation, and will not be blocked by the flanges on both sides resulting in limited movement, which is convenient for adjusting the included angle between the first connecting member and the second connecting member.
[0040] Embodiment 2
[0041] The difference from Embodiment 1 is that the first connecting member and the second connecting member are connected by a pin. The pin shaft passes through the first connection hole, and the first connecting member and the second connecting member can rotate around the pin shaft.
[0042] In this embodiment, since the first connecting member and the second connecting member can rotate relative to each other, when the photovoltaic arrays 9 on both sides of the mountain peak or both sides of the valley are affected by wind, light, or vibration, and the angles of the photovoltaic arrays 9 change slightly, the connecting members can adapt by rotating and dissipate the deformation to release the stress.
[0043] It should be noted that the first connecting member and the second connecting member can also be connected by a hinge.
[0044] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are all included in the protection scope of the present invention.
