Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic panel technology, and in particular relates to a damping-type load-reducing photovoltaic module. Background Technology

[0002] Photovoltaic panels are energy-saving devices that convert solar energy into electrical energy to power equipment. Therefore, generating electricity using photovoltaic panels is not only energy-saving and environmentally friendly, but also a form of clean energy.

[0003] Therefore, the application of photovoltaic power generation technology is very widespread, which is reflected in the fact that photovoltaic power generation is gradually being used from land to places such as ponds, lakes, reservoirs and even the vast ocean.

[0004] Unlike photovoltaic panels installed on land, photovoltaic panels installed in environments such as ponds, lakes, reservoirs, and oceans are all floating on the water surface. Therefore, the requirements for the installation structure of photovoltaic panels are relatively high.

[0005] Specifically, because photovoltaic panels are installed floating on the water surface, when the water is affected by wind, the panels sway violently on the water's surface. Since the panels are mounted on a rigid frame, this violent swaying makes them prone to breakage. The reason is that photovoltaic panels are made of glass, which is relatively brittle. To accommodate the thermal contraction of the panels, there are often gaps between the frame and the panels themselves. This means that when the panels sway violently, uneven stress during the swaying process can easily cause the glass panels to break.

[0006] Therefore, if the technical problem of photovoltaic panels' installation stability cannot be solved when they are installed in aquatic environments such as ponds and lakes, their application will inevitably be highly limited. For example, they can only be used in shallow water environments. In shallow water environments, it is easy to fix the photovoltaic panels in place, but in deep water environments, they can only be installed floatingly. However, the above-mentioned defects make it easy for the photovoltaic panels to break after floating installation, so the application is very limited. Utility Model Content

[0007] Based on the above background, the purpose of this utility model is to provide a damped load-reducing photovoltaic module.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A damping-type load-reducing photovoltaic module includes a photovoltaic module, wherein the photovoltaic module includes a photovoltaic panel and a frame for mounting the photovoltaic panel;

[0010] The photovoltaic panel and the frame are connected by several male and female groove structures;

[0011] The photovoltaic panels and the frame are spaced apart;

[0012] The damped load-reducing photovoltaic module also includes several pairs of spring bearing mechanisms, each pair of spring bearing mechanisms being elastically clamped on both sides of the photovoltaic panel;

[0013] Each spring bearing mechanism includes a spring seat, in which a torsion spring is fixedly connected. The spring bearing mechanism also includes a roller that elastically abuts against the photovoltaic panel. An axle is rotatably connected to the roller, and the axle is fixedly connected to the torsion spring.

[0014] Preferably, a spring rod sleeved inside the torsion spring is fixedly connected inside the spring seat, one end of the torsion spring abuts against the spring seat, and the other end of the torsion spring is fixed to the axle.

[0015] Preferably, both the male and female slot structures include irregularly shaped protrusions fixedly connected to the corner of the photovoltaic panel;

[0016] The frame is provided with a limiting groove that is adapted to the irregular protrusion.

[0017] Preferably, the irregular protrusion includes a curved portion, and the curved portion is integrally formed with a connecting portion connected to the photovoltaic panel.

[0018] Preferably, the photovoltaic panel has a rectangular cross-sectional shape and four corner sections, each of which is connected to the frame via a male-female groove structure.

[0019] Preferably, three spring-supporting mechanisms are symmetrically distributed on each of the front and rear sides of the top of the photovoltaic module;

[0020] The spring-supporting mechanism has three symmetrically distributed on each of the front and rear sides of the bottom of the photovoltaic module.

[0021] Preferably, the photovoltaic module has several damping structures distributed at both the top and bottom.

[0022] Preferably, the damping structure includes a damper installed between the photovoltaic panel and the frame.

[0023] Preferably, three dampers are distributed on each of the left and right sides of the top of the photovoltaic module;

[0024] The photovoltaic module has three dampers distributed on each of its bottom left and right sides.

[0025] This utility model has the following beneficial effects:

[0026] 1. During operation, after the photovoltaic panel is installed, the rollers are elastically pressed against the photovoltaic panel due to the spring force of the torsion spring. When the photovoltaic panel shakes or vibrates during use (in the current method, the entire device is subsequently installed on a floating frame on the water surface), and when the wind blows, the swaying photovoltaic panel shakes, moves, and vibrates violently. Therefore, the elastic pressing and clamping of the rollers increases the stability of the photovoltaic panel. For example, during the shaking of the photovoltaic panel, the elastically connected rollers vibrate elastically. Also, during the movement of the photovoltaic panel (there is a gap between the photovoltaic panel and the frame), the rollers rub against the photovoltaic panel, further cushioning the movement through friction.

[0027] The above method fully protects the photovoltaic panels, solving the technical defects of poor stability and easy breakage of photovoltaic panels after floating installation in strong winds.

[0028] 2. The use of dampers further protects the glass photovoltaic panels and reduces the technical defects of photovoltaic panel fragments. Attached Figure Description

[0038] Example 1

[0039] like Figure 1-4 As shown, a damped load-reducing photovoltaic module includes a photovoltaic module, which is the same as existing photovoltaic modules. The photovoltaic module includes a photovoltaic panel 2 (the photovoltaic panel 2 is a conventional solar photovoltaic panel 2 disclosed in the prior art, which is rectangular in shape) and a frame 1 of a rectangular structure for mounting the photovoltaic panel 2.

[0040] To ensure stable installation of the photovoltaic panel 2, the photovoltaic panel 2 is connected to the frame 1 via several male and female groove structures. Specifically, the photovoltaic panel 2 has four corner sections, each of which is connected to the frame 1 via a male and female groove structure.

[0041] Meanwhile, both the male and female slot structures include irregularly shaped protrusions 21 fixedly connected to the corner of the photovoltaic panel 2; the frame 1 is provided with a limiting slot 11 adapted to the irregularly shaped protrusions 21. The irregularly shaped protrusions 21 include curved portions 211, and the curved portions 211 are integrally formed with connecting portions 212 connected to the photovoltaic panel 2.

[0042] During installation, following the existing method, the photovoltaic panel 2 is placed and installed along the mounting grooves around the frame 1. At this point, the male and female groove structures at the four corners increase installation stability. Specifically, because the curved part-connecting part of the irregular structure fits into the shape-matching limiting groove 11, the rectangular photovoltaic panel 2 is restrained at the four corners. This method increases the installation stability of the photovoltaic panel 2.

[0043] Because the photovoltaic panel 2 and the frame 1 are spaced apart; specifically, the photovoltaic panel 2 needs to have a certain gap between itself and the frame 1 to provide a buffer space for the thermal expansion and contraction of the photovoltaic panel 2 (there is also a gap between the curved part 211-connecting part 212 and the limiting groove 11), the stability of the photovoltaic panel 2 is not high. Therefore, the above-mentioned damping type load-reducing photovoltaic module also includes several pairs of spring bearing mechanisms 3.

[0044] Specifically, three spring-loaded mechanisms 3 are symmetrically distributed on each of the front and rear sides of the top of the photovoltaic module; three spring-loaded mechanisms 3 are symmetrically distributed on each of the front and rear sides of the bottom of the photovoltaic module. With the cooperation of the two spring-loaded mechanisms 3 at the top and bottom, the photovoltaic panel 2 is elastically clamped. At the same time, the spring-loaded mechanisms 3 increase stability when the photovoltaic panel 2 moves.

[0045] Specifically, each spring bearing mechanism 3 includes a spring seat 31, in which a torsion spring 32 is fixedly connected. The spring bearing mechanism 3 also includes a roller 33 that elastically abuts against the photovoltaic panel 2. An axle 331 is rotatably connected to the roller 33, and the axle 331 is fixedly connected to the torsion spring 32.

[0046] Specifically, a spring rod 34 is fixedly connected inside the spring seat 31 and sleeved inside the torsion spring 32. One end of the torsion spring 32 abuts against the spring seat 31, and the other end of the torsion spring 32 is fixed to the axle.

[0047] After the photovoltaic panel 2 is installed, the roller 33 is elastically pressed against the photovoltaic panel 2 due to the elastic force of the torsion spring 32. When the photovoltaic panel 2 shakes or vibrates during use (in the current method, the entire device is subsequently floated on a floating frame on the water surface), and when the wind blows, the swaying photovoltaic panel 2 shakes, moves, and vibrates violently. Therefore, the elastic pressing and clamping of the roller 33 increases the stability of the photovoltaic panel 2. For example, during the shaking of the photovoltaic panel 2, the elastically connected roller 33 vibrates elastically. And during the movement of the photovoltaic panel 2 (there is a gap between the photovoltaic panel 2 and the frame 1), the roller 33 rolls on the photovoltaic panel 2 with friction, further cushioning the movement through friction.

[0048] The above method fully protects the photovoltaic panel 2, solving the technical defects of poor stability and easy breakage of the photovoltaic panel 2 after floating installation in strong winds.

[0049] Example 2

[0050] like Figure 1-4 As shown, in this embodiment, based on the structure of Embodiment 1, to further protect the photovoltaic panel 2, several damping structures are distributed at the top and bottom of the photovoltaic module in the existing manner. Specifically, the damping structures are installed between the photovoltaic panel 2 and the frame 1 according to the existing installation method.

[0051] The damping structure specifically adopts the hydraulic damper disclosed in the existing technology. Specifically, three dampers 4 are distributed on the top left and right sides of the photovoltaic module; and three dampers 4 are distributed on the bottom left and right sides of the photovoltaic module.

[0052] Specifically, the main body of the damper 4 is fixedly mounted on the frame 1, and its force-bearing contact end abuts against the photovoltaic panel 2. With the clamping cooperation of the damping structures on both sides, the photovoltaic panel 2 is protected by the buffering effect of the damper 4 when it vibrates violently.

[0053] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
