[0026] A photovoltaic panel mounting structure for color steel roof tiles is disclosed, wherein a protrusion 1 is formed on the color steel roof tile. The protrusion 1 on the color steel roof tile is prior art and will not be elaborated upon. The purpose of this application is to fix the photovoltaic panel 9 relative to the protrusion 1, thereby significantly saving the area on the color steel roof tile used for mounting the photovoltaic panel 9; thus, it is beneficial to increase the usable area of other aspects of the roof, resulting in better roof integrity, better waterproofing, and improved anti-aging and delayed protection effects. The mounting structure is used to install the photovoltaic panel 9 on the protrusion 1. One side of the protrusion 1 is fixed to the color steel roof tile, and the other side extends away from the color steel roof tile and is provided with an outwardly protruding locking portion. Specifically, the protrusion 1 is a right-angled trapezoid, and the small end of the protrusion 1 is integrally formed with the color steel roof tile. The mounting structure includes: a first clamp 2, a second clamp 3, and a locking member 4. The first clamp 2 is used to abut against one side of the protrusion 1, and the second clamp 3 is used to form a slot 11 that is embedded in the card portion. The locking member 4 is used to fix the first clamp 2 and the second clamp 3, and to form a wrapping groove 5 to accommodate the protrusion 1, so that the first clamp 2 and the second clamp 3 are fixed to the protrusion 1; the photovoltaic panel 9 is fixed to the color steel tile at least by the first clamp 2 and the second clamp 3.
[0027] By adopting the above technical solution, the first clamp 2 and the second clamp 3 are joined together by the locking member 4 to form a wrapping groove 5, which wraps around the protrusion 1, thereby fixing the first clamp 2 and the second clamp 3 to the protrusion 1. This fixing method is simpler, requires no drilling, and is easy to disassemble. It facilitates installation and improves the stability of the photovoltaic panel 9 after installation.
[0028] Specifically, a limiting body 6 is formed between the first clamp 2 and the second clamp 3. The limiting body 6 is used to abut against the first clamp 2 and the second clamp 3 when the wrapping groove 5 is formed. An elastic mounting area is formed between the limiting body 6 and the wrapping groove 5. The locking member 4 is disposed in the elastic mounting area and exerts a locking force on the first clamp 2 and the second clamp 3 to bring them closer together. The limiting body 6 includes a first abutting part and a second abutting part. The first abutting part is fixed to the first clamp 2, and the second abutting part is fixed to the second clamp 3. The first abutting part is used to abut against the second clamp 3, and the second abutting part is used to abut against the first clamp 2. In this design, both the first clamp 2 and the second clamp 3 are plate structures. After the first clamp 2 and the second clamp 3 are locked together by the locking member 4, a gap is formed between them. By inserting the limiting body 6 into the gap, a contact is provided between the first clamp 2 and the second clamp 3, which helps the retractable member to have a reaction force when locking the first clamp 2 and the second clamp 3, thus increasing the locking effect. In addition, since the first clamp 2 and the second clamp 3 are both plates, they can deform. After the locking member 4 locks them together, it can cause the first clamp 2 and the second clamp 3 to deform, thus making the locking more secure. The presence of the limiting body 6 prevents the first clamp 2 and the second clamp 3 from deforming excessively, which would make it difficult to form the wrapping groove 5. The limiting body 6 can be a plate. Furthermore, this application preferably includes a first abutting part and a second abutting part, both of which are plates. Among them, the locking component 4 adopts a double-ended stud or bolt.
[0029] Specifically, purlins 7 and connectors 8 are provided on the first clamp 2 and the second clamp 3; the connectors 8 are disposed above the purlins 7, and the photovoltaic panel 9 is fixed to the connectors 8; the purlins 7 are used to connect the connectors 8 to the first clamp 2 or the second clamp 3.
[0030] Specifically, the first clamp 2 or the second clamp 3 has a toothed surface formed on it to support the purlin 7. The toothed surface increases the friction with the purlin 7, making the fixation more secure.
[0031] Specifically, the connection structure includes a crossarm 81 and a pressure block 82. An insertion hole is formed on the photovoltaic panel 9. The pressure block 82 is partially inserted into the insertion hole and is fixed to the crossarm 81, which in turn is fixed to the purlin 7. A pressure surface is formed on the pressure block 82 to press down on the photovoltaic panel 9. The pressure block 82 presses down on the photovoltaic panel 9, achieving complete positioning of the photovoltaic panel 9. A groove is formed in the pressure block 82, and screws or bolts are installed in the groove to fix the pressure block 82 to the crossarm 81.
[0032] Specifically, the connection structure also includes a connector 83, which supports the crossarm 81 to separate it from the purlin 7. The purpose is to form transverse and longitudinal grooves between the crossarm 81 and the purlin 7, both of which are used to drain water from below the photovoltaic panel 9.
[0033] Specifically, a cavity is formed in the middle of the connector 83, and an inclined surface is formed on the edge of the connector 83; the crossbeam 81 is fixed to the inclined surface and is placed horizontally on the cavity.
[0034] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
