Description

A bolt-fastened photovoltaic module connector

Technical Field

The present application relates to the technical field of photovoltaic panel installation, and in particular to a bolt-fastened photovoltaic component connector.

Background Art

Photovoltaic is the abbreviation of solar photovoltaic power generation system. It is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. In the process of photovoltaic power generation, photovoltaic roof systems are often needed. Photovoltaic roof systems are a way to integrate solar photovoltaic power generation systems into building roofs. It uses the roof space of the building to install solar photovoltaic panels on the roof to convert sunlight into electrical energy. When setting up solar photovoltaic panels on aluminum-magnesium-manganese metal roofs, metal roof panels need to be installed on the metal roofs through windproof clamps. Solar photovoltaic panels need to be reliably connected to metal roof panels through connectors. Therefore, the windproof stability of metal roof panels directly affects the reliability of solar photovoltaic panel connections.

A Chinese patent with application number CN202021032465.2 in the related technology proposes a vertical lock-edge roof windproof clamp, which includes two symmetrically arranged plywood, and the plywood includes an upper extension plate, an arc plate and a lower extension plate from top to bottom. The upper extension plate and the lower extension plate are located on the same vertical plane. The arc plate is semi-circular and has a bolt hole on the upper extension plate. A semi-circular notch is provided on the upper extension plate. The center of the semi-circular notch is located at the center of the length direction of the plywood. A stud is inserted into the bolt hole to fix the two mating plywood. The arc plates on the two plywood are aligned to form a circle, and the notches on the two plywood are aligned to form a circular hole.

Referring to Figure 1, the T-code support 1 is fixed on the roof 6, and the length direction of the T-code support 1 is consistent with the inclination direction of the slope surface of the roof 6. Roof panels 2 are arranged on both sides of the T-code support 1, and the side of the roof panel 2 close to the T-code support 1 is bent into a hook portion 23, wherein the hook portions 23 of the two roof panels 2 are overlapped and buckled on the top of the T-code support 1, and the hook portions 23 of the two roof panels 2 are tightly fitted; the two arc plates 7 are respectively rotated and buckled on both sides of the T-code support 1, and by tightening the studs 8, the inner wall of the arc plate 7 tightly buckles the hook portion 23 of the roof panel 2 on the top of the T-code support 1, and at this time, the hook portion 23 of the roof panel 2 is completely and tightly fitted with the inner wall of the arc plate 1. The roof panel 2 is tightly pressed against the top of the T-code support 1 through the curved plate 1, so that the roof panel 2 is stably installed on the roof due to the friction between the roof panel 2 and the inner wall of the curved plate 1 and the friction between the roof panel 2 and the T-code support 1.

Regarding the above-mentioned related technologies, when the roof panel is exposed to sunlight for a long time in the summer, its temperature rises rapidly. At this time, the roof panel will freely expand and contract along the inclination direction of the roof to release the stress caused by the temperature; since multiple clamps are installed at intervals on the T-code support, the T-code support, the clamp and the roof panel have different performances in adapting to thermal expansion and contraction, so that the expansion and contraction of the roof panel where the clamp is installed is restricted, causing the hook part of the roof panel between the two clamps to bulge or tear, resulting in the hook parts of the two roof panels cannot fit tightly and the bite effect is poor; in windy weather, the airflow will enter between the roof panel and the roof through the gap between the hook parts of the two roof panels, making the roof panel easily overturned from the roof by the airflow, thereby affecting the windproof ability of the roof panel, and then making it difficult to stably install the photovoltaic modules on the roof panel.

Utility Model Content

In order to improve the problem that the hook portion of the roof panel is prone to tearing or bulging, which reduces its windproof ability and affects the stability of the photovoltaic module installation on the roof panel, the present application provides a bolt-fastened photovoltaic module connector.

The present application provides a bolt-fastened photovoltaic module connector that adopts the following technical solution:

A bolt-fastened photovoltaic module connector comprises a roof, a plurality of roof panels laid on the roof, and a plurality of photovoltaic panels installed on the roof panels. The connector comprises

The T-code support has a base at the bottom fixed on the roof, a web in the middle of the T-code support is located between two adjacent roof panels, and a support head at the top of the T-code support extends above the roof; the edge of the roof panel is bent upward to form a leaning portion against the web, and the edge of the leaning portion is bent downward to form a hook portion buckled on the support head, and the hook portions of two adjacent roof panels are staggered and overlapped on the T-code support;

A buckle is buckled on the T-code support, the buckle includes a buckle buckled on two staggered overlapping hook parts, so that the hook parts in the buckle can freely expand and contract; the buckle also includes an elastic part located in the buckle and capable of adapting to the expansion and contraction of the leaning part, and a pressing part located on the buckle and used to drive the elastic part to press the leaning part against the web; and

The photovoltaic mounting rail is fixedly mounted on the top of the buckle and is used to set up and install the photovoltaic panel.

By adopting the above technical solution, when installing the connecting piece, it is only necessary to first fix the base of the T-code support to the roof, at which time the length direction of the T-code support is consistent with the inclination of the roof, and the web of the T-code support is perpendicular to the roof; then the roof panels are laid on both sides of the T-code support, the roof panels are laid on the upper surface of the roof, and the side of the roof panel close to the T-code support is bent in sequence to form a leaning part and a hook part, the leaning parts of the two roof panels are respectively against the side walls on both sides of the web, and the hook parts of the two roof panels are overlapped and buckled on the support head; then the buckle is buckled on the hook part, and the elastic part is driven by the tightening part to tighten the leaning part against the web, so that the roof panel is stably installed on the roof. Since the hook part of the roof panel can be freely expanded and contracted in the buckle, the hook part can be freely expanded and contracted with the change of temperature, and no bulge or tearing will occur, so that the airflow is not easy to enter between the roof panel and the roof, thereby ensuring the windproof ability of the roof panel. At the same time, the elastic member pressed against the leaning part can adapt to the expansion and contraction of the leaning part, avoiding bulging or tearing of the leaning part after expansion and contraction, and further ensuring the windproof ability of the roof panel.

Optionally, the buckle includes an upper plate located above the support head and two side plates connected to the upper plate and located on both sides of the web, the elastic members are provided in two groups, the two groups of elastic members are respectively located on both sides of the web, and the clamping members are also provided in two groups, the two groups of clamping members are respectively located on the two side plates.

By adopting the above technical solution, two groups of fastening members are distributed on both sides of the web through two side plates, and the two groups of fastening members respectively fasten the leaning parts of the two roof panels to the side walls on both sides of the web through elastic members, so that greater friction is generated between the leaning part of the roof panel and the web, thereby stably installing the roof panel on the T-code support and the roof. On the one hand, the part of the roof panel that is fastened is located on the leaning part, and the deformation of the leaning part caused by temperature change is not enough to cause the hook part to bulge or tear, thereby ensuring the fit of the two hook parts overlapped, and at the same time, the elastic member that is fastened to the leaning part can adapt to the expansion and contraction of the leaning part, avoiding the leaning part from bulging or tearing after expansion and contraction, thereby ensuring the windproof ability of the roof panel. On the other hand, since the leaning part is located on the windward side, the leaning part is more susceptible to the influence of airflow, and the fastening member presses the leaning part against the web, which can reduce the deformation of the leaning part caused by airflow interference, thereby further ensuring the windproof ability of the roof panel.

Optionally, there are multiple clamping members in the same group, and there are multiple elastic members in the same group, the multiple elastic members correspond to the multiple clamping members one by one, and the multiple clamping members are spaced apart along the length direction of the side plate.

By adopting the above technical solution, multiple clamping members are arranged at intervals along the length direction of the side panels, so that the leaning part of the roof panel is stably pressed against the web, which not only improves the stability of the roof panel installation, but also effectively prevents the leaning part from being deformed by the airflow, thereby ensuring the wind-proof ability of the roof panel.

Optionally, the fastening member is configured as a bolt threadedly passing through the side plate, and the bolt is arranged perpendicular to the web.

By adopting the above technical solution, the bolts are driven to rotate quickly, and the bolts push the elastic member to quickly and tightly press the leaning part against the web, thereby completing the rapid installation of the roof panel.

Optionally, the elastic member is configured as a rubber pad.

By adopting the above technical solution, the rubber pad has good ductility, elasticity and a large friction coefficient, so that the rubber block can press the leaning part against the belly plate when driven by the bolts, which can not only reduce the pressure damage to the leaning part, but also increase the stability of the installation of the leaning part. The rubber pad can adapt to the expansion and contraction of the leaning part, and effectively avoid the bulge or tearing of the leaning part caused by the obstruction of expansion and contraction.

Optionally, a slope abutting against the hook portion is provided on a side of the rubber pad close to the hook portion.

By adopting the above technical solution, the inclined surface is set so that when the rubber pad is pressed against the leaning part, its inclined surface can stably abut against the hook part, which not only improves the stability of the buckle on the T-code support, but also prolongs the service life of the rubber pad.

Optionally, the bolt is provided with an anti-loosening structure for preventing the bolt from loosening on the side plate.

By adopting the above technical solution, the anti-loosening structure can improve the stability of the bolts installed on the side panels, so that the supporting part is stably pressed against the web under the joint action of the bolts and the rubber pads, thereby improving the stability of the roof panel installation.

Optionally, the anti-loosening structure is a gasket sleeved on the bolt, and the gasket is located between the side plate and the nut of the bolt.

By adopting the above technical solution, the provision of the gasket can increase the friction between the bolt nut and the side plate, so that the bolt is stably positioned on the side plate.

Optionally, the anti-loosening structure is a nut threadedly mounted on the bolt, and the nut and the nut of the bolt are respectively located on both sides of the side plate.

By adopting the above technical solution, when the rubber pad presses the leaning part against the belly plate, the nut and/or the nut press against the side walls on both sides of the side plate respectively, so that the bolt is stably positioned on the side plate.

Optionally, the base is provided with a mounting piece for quickly connecting the base to the roof.

By adopting the above technical solution, the mounting piece can quickly connect the base to the roof, thereby completing the rapid and stable installation of the T-code support and improving the efficiency of the roof panel installation.

In summary, the present application includes at least one of the following beneficial technical effects:

1. Since the hook of the roof panel can freely expand and contract in the buckle, the hook can expand and contract freely with the change of temperature without bulging or tearing, making it difficult for airflow to enter between the roof panel and the roof, thus ensuring the windproof ability of the roof panel;

2. The part of the roof panel that is pressed tightly is located on the leaning part. The deformation of the leaning part due to temperature change is not enough to cause the hook part to bulge or tear, which ensures the fit of the two hook parts, and further ensures the windproof ability of the roof panel. At the same time, because the leaning part is located on the windward side, it is more susceptible to the influence of airflow, and the pressing member presses the leaning part tightly against the web, which can reduce the deformation of the leaning part caused by airflow interference, and further ensures the windproof ability of the roof panel;

3. The rubber pad has good ductility, elasticity and a large friction coefficient, so that the rubber block can press the leaning part against the belly plate under the drive of the bolt, which can not only reduce the pressure damage to the leaning part, but also increase the stability of the installation of the leaning part. The rubber pad can adapt to the expansion and contraction of the leaning part, effectively avoiding the bulge or tearing of the leaning part caused by the obstruction of expansion and contraction.

DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are 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.

The embodiment of the present application discloses a bolt-fastened photovoltaic assembly connector.

Referring to Figures 2, 3, 4 and 5, a bolt-fastened photovoltaic module connector includes a T-code support 1, a fastener and a photovoltaic mounting rail 9. The T-code support 1 is fixedly mounted on the roof 6, and roof panels 2 are arranged on both sides of the T-code support 1, and the roof panels 2 are laid on the roof 6; the fastener includes a buckle 3, an elastic member and a fastening member 4, the buckle 3 buckles one side of the roof panel 2 on the top of the T-code support 1, and the fastening member 4 fastens the elastic member on the roof panel 2, so that the roof panel 2 is stably locked on the T-code support 1. Subsequently, the photovoltaic mounting rail 9 is installed on the top of the buckle 3, and a plurality of photovoltaic panels 20 are installed on the roof panel 2 through the photovoltaic mounting rail 9.

2 and 3 , the T-code support 1 includes an integrally formed base 11, a web 12 and a support head 13. The base 11 is vertically arranged at the bottom of the web 12, and the support head 13 is located at the top of the web 12. The base 11 is provided with a mounting member 5 for quickly connecting the base 11 with a bottom plate 62. The mounting member 5 is specifically a screw. The base 11 is stably mounted on the bottom plate 62 by means of the screws. The web 12 is sequentially penetrated with insulation material 63 and a top plate 64, and the support head 13 is located above the top plate 64.

2 and 4 , the roof panels 2 are located on both sides of the T-code support 1, and the roof panels 2 include a flat portion 21 laid on the upper surface of the top plate 64, and the flat portion 21 is bent in sequence on one side close to the T-code support 1 to form a leaning portion 22 and a hook portion 23, and the leaning portions 22 of the two roof panels 2 are respectively abutted against the side walls on both sides of the web 12, and the hook portions 23 of the two roof panels 2 are staggered and buckled on the support head 13.

2 and 5 , the buckle 3 includes an upper plate 31 and two side plates 32 which are integrally formed. The upper plate 31 and the two side plates 32 are combined to form an inverted U-shaped buckle. The buckle 3 buckles the hook portion 23 on the support head 13. At this time, the upper plate 31 contacts the top of the hook portion 23, and the bottom of the side plate 32 extends to the web 12. The inner wall of the buckle 3 contacts the hook portion 23 but does not press tightly, so that the hook portion 23 can be freely expanded and contracted in the buckle 3 under the influence of temperature, effectively avoiding the bulge or tearing of the hook portion 23 due to the obstruction of expansion and contraction, and avoiding a large amount of airflow from entering between the roof panel 2 and the roof 6, thereby ensuring the windproof ability of the roof panel 2.

2 and 5, two groups of fastening members 4 are provided, and the two groups of fastening members 4 are respectively located on the two side plates 32, and there are multiple fastening members 4 in the same group. The number of fastening members 4 can be adjusted according to the length of the buckle 3. In the embodiment of the present application, four fastening members 4 are provided in the same group, and the four fastening members 4 are arranged on the side plates 32 at intervals along the length direction of the buckle 3. The fastening member 4 is a bolt 41 threadedly penetrated through the side plate 32, the bolt 41 is arranged vertically on the web 12, and the nut of the bolt 41 is located outside the buckle 3. The elastic member is set as a rubber pad 42, and a slope is set on the side of the rubber pad 42 close to the hook portion 23, and a threaded hole is opened on the rubber pad 42, and the rubber pad 42 is threadedly connected to the bolt 41.

The bolt 41 is turned, and the bolt 41 pushes the rubber pad 42 to press the leaning portion 22 against the web 12, and at this time, the inclined surface of the rubber pad 42 abuts against the bottom of the hook portion 23. Since the rubber pad 42 has good ductility, elasticity and a large friction coefficient, the rubber block presses the leaning portion 22 against the web 12 under the drive of the bolt 41, which not only reduces the pressure injury to the leaning portion 22, but also increases the stability of the installation of the leaning portion 22, and the rubber pad 42 can adapt to the expansion and contraction of the leaning portion 22, effectively avoiding the bulge or tearing of the leaning portion 22 caused by the obstruction of expansion and contraction.

In order to further improve the tightening effect of the rubber pad 42 on the leaning portion 22, referring to Figures 2 and 5, the bolt 41 is provided with an anti-loosening structure for preventing the bolt 41 from loosening on the side plate 32. In the embodiment of the present application, the anti-loosening structure is provided as a gasket 43 sleeved on the bolt 41. The gasket 43 is located between the side plate 32 and the nut of the bolt 41, and the nut presses the gasket 43 against the side plate 32, so that the bolt 41 is not easy to rotate relative to the side plate 32, and then the bolt 41 can stably press the leaning portion 22 against the web 12 through the rubber pad 42.

Then move the bent roof panel 2 to the T-code support 1, so that the hook portions 23 of the roof panels 2 on both sides of the T-code support 1 are staggered and buckled on the support head 13, the leaning portion 22 is attached to the web 12 of the T-code support 1, and the flattened portion 21 is laid on the top plate 64. Then buckle the buckle 3 on the hook portion 23, and rotate the bolt 41 at the same time. The bolt 41 stabilizes the leaning portion 22 against the web 12 through the rubber pad 42, and the installation of the roof panel 2 is completed. Finally, use screws to install the photovoltaic mounting rail 9 on the buckle 3, fix multiple photovoltaic panel clamps 10 on the upper surface of the photovoltaic mounting rail 9 at intervals along the length direction of the photovoltaic mounting rail 9, and stably clamp the photovoltaic panel 20 between two adjacent photovoltaic panel clamps 10.

Embodiment three:

7 , the difference between the third embodiment and the second embodiment lies in the anti-loosening structure. In order to stably lock the longer bolt 41 on the side plate 32, in the embodiment of the present application, the anti-loosening structure is a nut 44 threadedly sleeved on the bolt 41, and the nut 44 and the nut are respectively located on both sides of the side plate 32; when the rubber pad 42 is pressed against the supporting portion 22 by the bolt 41, the nut 44 is driven to rotate on the bolt 41, so that the nut 44 is pressed against the inner wall of the side plate 32, so that the bolt 41 is not easy to rotate relative to the side plate 32, and the bolt 41 can stably press the supporting portion 22 against the web 12 through the rubber pad 42.
