[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It mainly consists of three parts: solar panels (photovoltaic modules), controllers and inverters. After being connected in series and packaged for protection, solar cells can form large-area solar panels, which, combined with power controllers and other components, form a photovoltaic power generation system.

[0003] Large-scale photovoltaic power plants usually lay out arrays of numerous photovoltaic power generation systems on the ground to increase power generation capacity. However, in some places with small ground areas, it is impossible to lay out arrays of multiple photovoltaic power generation equipment at the same time.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] Reference Figures 1 to 6 As shown, the embodiment of the utility model provides an angle-adjustable photovoltaic module frame, including two longitudinal long frames 1 and four transverse short frames 2, the two long frames 1 are arranged opposite to each other at intervals, the two ends of the two long frames 1 are respectively and vertically detachably plugged with short frames 2, and the two short frames 2 located on the same side are hinged to each other at one end away from the long frames 1; a support connecting rod 3 is detachably connected between the two short frames 2 plugged at the two ends of the same long frame 1, and the support connecting rod 3 is located at the bottom of the two short frames 2, does not affect the installation of the photovoltaic module, and forms a support from the bottom of the photovoltaic module, specifically as shown Figure 1 As shown, each frame is connected to form a frame structure with a middle hinge and can be bent. With the hinge position as the central axis, a frameless photovoltaic module can be installed on each side, or a flexible photovoltaic module with a middle foldable structure can be installed on the entire frame.

[0031] Specifically, there are two short frames 2 at both ends of the long frame 1, one end of the two short frames is hinged, and the other end is connected to the end of the two long frames 1 on the opposite side; the entire frame is composed of four short frames 2 and two long frames 1, wherein the length of each side is customized according to the size of the photovoltaic module installed inside.

[0032] In actual use, the two mutually hinged short frames 2 can rotate relative to each other, and then during the actual construction and installation of the photovoltaic module, the angle can be adaptively adjusted according to the corner conditions of the installation area to adapt to the installation area and facilitate use.

[0033] Specifically, each of the long frames 1 , the short frames 2 , and the supporting connecting rods 3 are made of aluminum alloy.

[0034] Further optimization scheme, such as Figure 2 and Figure 5 As shown, the short frame 2 is plugged and fixed on the end of the long frame 1, so as to achieve the purpose of quick installation and removal.

[0035] Specifically, two plug-in slots 4 are formed at the end of the long frame 1 , one above the other. Correspondingly, two plug-in rods 5 matching the plug-in slots 4 are protruded from the side of the short frame 2 facing the long frame 1 .

[0036] Further optimization scheme, such as Figure 5 and Figure 6 As shown, a pressing piece 8 is fixedly connected to the upper and lower inner walls of the plug slot 4, one end of the pressing piece 8 is fixedly connected to the inner wall of the plug slot 4, and the other end is a free end, and the free end is elastically connected to the inner wall of the plug slot 4; the upper and lower pressing pieces 8 in the same plug slot 4 are symmetrically arranged and the free ends are close to each other. Correspondingly, the plug rod 5 is fixedly connected to the side of the short frame 2, and the end of the plug rod 5 away from the short frame 2 has a clamping joint 10 with upper and lower protrusions, and the clamping joint 10 cooperates with the free end of the pressing piece 8 to form a clamping connection.

[0037] To further optimize the solution, a spring 9 is connected between the free end of the pressing piece 8 and the inner wall of the plug-in slot 4, and an elastic connection is achieved through the spring 9. When the plug-in rod 5 is inserted, the spring 9 is compressed, and the pressing piece 8 is close to the inner wall of the plug-in slot 4 to accommodate the smooth insertion of the plug-in rod 5. When the card connector 10 of the plug-in rod 5 passes over the free end of the pressing piece 8, the pressing piece 8 is pressed against the inner wall of the plug-in slot 4 under the action of the spring 9, so that the free end of the pressing piece 8 is against the root of the card connector 10 to form a card connection.

[0038] According to a further optimization scheme, the clamping connector 10 has a smoothly transitioned arc surface. Specifically, the clamping connector 10 is an elliptical structure to facilitate quick insertion to form a clamping connection.

[0039] According to a further optimization scheme, the clamping joint 10 is made of rubber material, can be deformed, and has a large surface friction.

[0040] When the long frame 1 and the short frame 2 are plugged in, the plug-in rod 5 on the short frame 2 is inserted into the plug-in slot 4 at the end of the long frame 1, and the card connector 10 presses against the pressure piece 8 inside the plug-in slot 4, so that the spring 9 between the pressure piece 8 and the plug-in slot 4 is in a compressed state. As the plug-in rod 5 enters, the card connector 10 passes over the free end of the pressure piece 8, the pressing force on the pressure piece 8 disappears, the compressed force of the spring 9 is released, and the pressure piece 8 rebounds to press against the card connector 10, completing the card connection and fixation; when disassembling the short frame 2, since the card connector 10 is made of rubber material and has a certain elasticity, the plug-in rod 5 can be pushed out by squeezing the card connector 10, thereby realizing quick disassembly.

[0041] It should be understood that a cover plate of the plug-in slot 4 is detachably covered on the outside of the plug-in slot 4 , that is, on the outside of the long frame 1 , so as to facilitate opening the cover plate and squeezing the card connector 10 during disassembly.

[0042] After the long frame 1 and the short frame 2 are connected, the supporting connecting rod 3 is placed between the two short frames 2 in the longitudinal direction, and the two ends of the supporting connecting rod 3 are respectively fixed to the bottom of the two short frames 2 by screws; specifically, a through hole is provided on the side of the short frame 2, and a threaded hole is provided at the end of the supporting connecting rod 3 to facilitate screw fastening connection.

[0043] According to a further optimized solution, the supporting connecting rod 3 is arranged close to the hinged end of the short frame 2 .

[0044] A further optimized solution is that a connecting ear piece 6 is fixedly connected to the short frame 2 near the hinged end, an axial hole is provided at the end of the connecting ear piece 6 away from the short frame 2, and the two connecting ear pieces 6 are rotatably connected to a connecting block 7, and the connecting block 7 and the two connecting ear pieces 6 are interference fit.

[0045] According to a further optimized solution, an anti-dropout end cover 11 is provided on the end surface of the connection block 7 , and the anti-dropout end cover 11 is threadedly connected to the connection block 7 .

[0046] The parts not described in detail in the present invention are all conventional technical means known to those skilled in the art.

[0047] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
