Description

Technical Field

[0001] The invention relates to the technical field of building photovoltaic integration, and more specifically to a photovoltaic wind-resistant clamp. Background Art

[0002] Crystalline silicon photovoltaic modules are power generation units composed of cells made of monocrystalline silicon or polycrystalline silicon. Crystalline silicon photovoltaic modules can be divided into framed photovoltaic modules and frameless photovoltaic modules according to different packaging processes. Framed photovoltaic modules have the advantages of good integrity, easy transportation and installation, and are widely used in distributed photovoltaic power stations and centralized photovoltaic power stations.

[0003] However, the application of framed photovoltaic modules on metal roofs is usually installed in a flat manner. It is necessary to first install a clamp (for fixing the upper guide rail) on the ribs of the metal roof panel, and then install the guide rail. The photovoltaic module is then fixed on the guide rail by a pressing block. On the one hand, the installation process requires multiple steps and the photovoltaic module is connected through multiple conversions. The connection reliability with the metal roof panel is not high, the wind resistance is not strong, and a photovoltaic module requires multiple guide rails, which is costly. On the other hand, because the slope of the metal roof is usually a gentle slope of about 5%, and because the frame of the photovoltaic module is often higher than the glass plane of the photovoltaic module, rainwater and dust on the surface of the photovoltaic module will accumulate at the bottom frame of the photovoltaic module. If it is not cleaned manually, the dust will accumulate more and more and cannot disappear by itself. The accumulated dust will form a hot spot effect on the photovoltaic module, which will reduce the power generation efficiency of the photovoltaic module and also pose a safety hazard.

[0004] Therefore, providing a photovoltaic wind-resistant clamp that is easy to install is an issue that needs to be urgently addressed by those skilled in the art. Summary of the invention

[0005] In view of this, the present invention provides a photovoltaic wind-resistant clamp, which can directly fix a photovoltaic module with a frame on a metal roof panel, and is easy to install and has high reliability.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0008] By adopting the above technical solution, the beneficial effects of the present invention are:

[0009] It has the functions of clamping, positioning, connecting and pressing, which can save the photovoltaic rails and realize the direct fixing of the photovoltaic components with frames on the metal roof panels. It is easy to install and has high reliability.

[0010] Furthermore, the opening and closing clamp includes a clamp fixed arm and a clamp movable arm, one end of the clamp fixed arm is provided with a fixed clamping rib, and the other end of the clamp fixed arm is provided with a female opening; a first threaded hole is provided in the center of the top of the clamp fixed arm; one end of the clamp movable arm is provided with a movable clamping rib, and the other end of the clamp movable arm is provided with a male buckle, and the male buckle is inserted into the female opening; the fixed clamping rib and the movable clamping rib are respectively clamped on the clamping ribs of the buckle.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1-8 As shown, the embodiment of the present invention discloses a photovoltaic wind-resistant clamp, including an opening and closing clamp 1, a pressing block 2 and a bolt 3. The opening and closing clamp 1 is clamped on the buckle 41 of the metal roof panel crest 4; the pressing block 2 is located at the top and periphery of the opening and closing clamp 1, and the pressing block 2 has an open end for the opening and closing clamp to open and close, one end of the pressing block 2 contacts the supporting plane 42 of the metal roof panel crest 4, and the other end of the pressing block 2 contacts the frame 5 of the photovoltaic module; the bolt 3 is screwed on the pressing block 2 and the opening and closing clamp 1 in sequence from top to bottom. The present invention has the functions of clamping, positioning, connecting and pressing, and can save the photovoltaic rails, so that the photovoltaic module with the frame 5 can be directly fixed on the metal roof panel, which is easy to install and has high reliability.

[0029] Specifically, the opening and closing clamp 1 includes a clamp fixed arm 11 and a clamp movable arm 12, a fixed clamping rib 111 is provided at one end of the clamp fixed arm 11, and a female opening 112 is provided at the other end of the clamp fixed arm 11; a first threaded hole 113 is provided at the center of the top of the clamp fixed arm 11; a movable clamping rib 121 is provided at one end of the clamp movable arm 12, and a male buckle 122 is provided at the other end of the clamp movable arm 12, the male buckle 122 is inserted into the female opening 112, and the male buckle 122 can rotate freely in the female opening 112; the fixed clamping rib 111 and the movable clamping rib 121 are respectively clamped on the clamping ribs of the buckle 41.

[0030] In order to further optimize the technical solution of the present invention, the female opening 112 is C-shaped, which can prevent the male buckle 122 from falling off from the female opening 112 .

[0031] Specifically, the pressing block 2 includes a pressing block body 21, a pressure plate 22 and a support plate 23 which are connected as one body. The pressing block body 21 is U-shaped, and the opening and closing clamp 1 is located between the two vertical plates of the pressing block body 21, which can restrain the clamp fixed arm 11 and the clamp movable arm 12 from being misaligned and separated; a second threaded hole 211 corresponding to the position of the first threaded hole 113 is provided in the center of the top of the pressing block body 21, and the bolt 3 is screwed into the second threaded hole 211 and the first threaded hole 113 from top to bottom in sequence; the pressure plate 22 is located at the top of one side of the pressing block body 21 to contact the frame 5 of the photovoltaic module; the support plate 23 is located at the bottom of the other side of the pressing block body 21 to contact the supporting plane 42 of the metal roof panel crest 4.

[0032] In order to further optimize the technical solution of the present invention, the pressing block body 21 and the pressure plate 22 are provided with a guide groove 221 extending to the outside of the pressure plate 22. Because the frame 5 of the photovoltaic module is higher than the glass surface of the photovoltaic module, affected by the slope, rainwater and dust on the surface of the photovoltaic module will accumulate at the lower edge of the photovoltaic module, and cannot be eliminated by themselves without manual cleaning. The present invention can drain the accumulated water retained at the lower edge of the frame 5 through the guide groove 221, and at the same time, the flow of the accumulated water takes away the dust of the photovoltaic module, thereby achieving the purpose of self-cleaning of the module.

[0033] In order to further optimize the technical solution of the present invention, the bottom of the pressure plate 22 has an anti-slip groove 222 corresponding to the anti-slip protrusion of the photovoltaic module frame 5, thereby preventing the pressure block 2 from falling off due to wind vibration, which can achieve better wind resistance.

[0034] Working process of the present invention:

[0035] Lift the movable arm 12 of the opening and closing clamp 1 so that the opening and closing clamp 1 is inserted into the metal roof panel crest 4, and drop the movable arm 12 so that the fixed clamping rib 111 and the movable clamping rib 121 are respectively clamped on the clamping ribs of the buckle 41 of the metal roof panel crest 4. At this time, the support plate 23 of the pressing block 2 is located on the support plane 42 of the metal roof panel crest 4, and the bolt 3 is rotated. When the thread of the bolt 3 is screwed into the first threaded hole 113, the opening and closing clamp 1 will be slowly lifted as the bolt 3 rotates, so that the fixed clamping rib 111 and the movable clamping rib 121 are clamped on the clamping rib to form a whole.
