Description

Technical Field

[0001] The invention relates to a photovoltaic panel installation node structure. Background Art

[0002] A photovoltaic array is a combination of multiple solar panels. The photovoltaic array is generally fixed to the fixed keel of a building through a conventional node structure. However, the existing conventional node structure can only match a special galvanized steel C-shaped keel, which is expensive and difficult to purchase on the market. The frame clips of the conventional node structure are not installed throughout the length, resulting in water leakage, and are inconvenient to install and disassemble. Moreover, the aluminum alloy frame clips of the conventional node structure are not installed throughout the length, resulting in water leakage. In addition, the photovoltaic array is inconvenient to install and disassemble. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a photovoltaic panel installation node structure which has a large material market selection space, is more economical, and is conducive to reducing the overall cost.

[0004] In order to solve the above technical problems, the present invention provides a photovoltaic panel installation node structure;

[0005] It includes a photovoltaic panel fixing frame, a first metal hanging weight, a second metal hanging weight, a metal base, fixing bolts and a fixing keel;

[0006] The fixed keel is a mesh structure formed by fixing a plurality of transverse square tubes and a plurality of longitudinal square tubes to each other, and the fixed keel is fixed on the outer surface of the building;

[0007] The bottom surface of the metal base is provided with a mounting groove matched with the fixed keel, a plurality of metal bases and a plurality of fixing bolts are in a one-to-one correspondence, the screw of the fixing bolt passes through the metal base and the fixed keel and is matched with the nut of the fixing bolt, a first hook protrusion and a second hook protrusion are extended from the end surface of the metal base away from the building, the first hook protrusion and the second hook protrusion are arranged at intervals, and the extension direction of the end of the first hook protrusion is consistent with the extension direction of the end of the second hook protrusion;

[0008] The photovoltaic panel fixed frame is fixedly connected to the edge of the back side of the solar photovoltaic panel, and any two adjacent photovoltaic panel fixed frames are respectively fixedly connected to the first metal hanging weight and the second metal hanging weight;

[0009] The first metal hanging weight is provided with a first hook portion and a first baffle portion, the first hook portion is located on the first metal hanging weight close to one side of the building, the first hook portion cooperates with the end of the first hook protrusion of the metal base, the first baffle portion is located in the middle of the first metal hanging weight, and the first baffle portion abuts against the side wall of the first hook protrusion away from the building;

[0010] The second metal hanging weight is also provided with a second hook-shaped portion and a second baffle portion. The second hook-shaped portion is located on the second metal hanging weight close to one side of the building. The second hook-shaped portion cooperates with the end of the second hook protrusion of the metal base. The second baffle portion is located in the middle of the second metal hanging weight. The second baffle portion abuts against the side wall of the second hook protrusion away from the building.

[0011] The distance between the first hook portion of the first metal hanging weight and the second hook portion of the second metal hanging weight is the same as the distance between the first hook protrusion and the second hook protrusion.

[0012] After adopting such a structure, the glue seam between the two adjacent solar photovoltaic panels after assembly is narrow, which greatly reduces the risk of water leakage. Since the first metal hanging weight and the second metal hanging weight are specially made, they are easy to install and disassemble, and the overall structure is safer and does not require maintenance at ordinary times.

[0013] The photovoltaic panel installation node structure has the advantages of large material market selection space, better economy, and is conducive to reducing overall costs.

[0014] The metal base of the photovoltaic panel installation node structure is provided with a waist-shaped hole penetrating its side wall, the length direction of the waist-shaped hole is consistent with the distance from the building, the screw of the fixing bolt passes through the waist-shaped hole of the metal base and the fixing keel and cooperates with the nut of the fixing bolt; after adopting such a structure, the photovoltaic panel installation node structure can have a certain position fine-tuning capability in the direction of the distance from the building, which is convenient for assembly in different environments.

[0015] Two aluminum alloy square washers are also mounted on the screw rod of the fixing bolt of the photovoltaic panel installation node structure. The aluminum alloy square washers are respectively located on both sides of the metal base. The two side walls of the metal base are respectively provided with serrated surfaces. The end faces of the aluminum alloy square washers are also provided with serrated surfaces that cooperate with the serrated surfaces of the metal base.

[0016] After adopting such a structure, due to the waist-shaped holes of the fixed keel, the entire photovoltaic panel installation node structure can have a certain position fine-tuning ability in the direction of the building, but at the same time, the assembled photovoltaic panel array has the hidden danger of displacement in the direction of the building, affecting the subsequent use. The serrated surface of the end face of the aluminum alloy square gasket cooperates with the serrated surface of the metal base to limit the displacement of the photovoltaic panel installation node structure in the direction of the building after the fixing bolts are assembled, thereby improving the safety and stability of the photovoltaic panel installation node structure in use.

[0017] The photovoltaic panel fixing frame of the photovoltaic panel installation node structure is fixedly connected to the back of the solar photovoltaic panel through silicone structural adhesive and double-sided adhesive.

[0018] The gap between two adjacent solar photovoltaic panels of the photovoltaic panel installation node structure is sealed by silicone weather-resistant sealant; after adopting such a structure, the gap between two adjacent solar photovoltaic panels is sealed by silicone weather-resistant sealant, which reduces the risk of water leakage between two adjacent solar photovoltaic panels.

[0026] The metal base 2 is a special base made of aluminum alloy. The bottom surface of the metal base 2 is provided with an installation groove that cooperates with the fixed keel 1. The metal base 2 and the fixing bolt 3 are in a corresponding relationship. The metal base 2 is provided with a waist-shaped hole 2a that runs through its side wall. The length direction of the waist-shaped hole 2a is consistent with the distance from the building. The fixing bolt 3 is an M6 stainless steel bolt group. Two aluminum alloy square gaskets 4 are also mounted on the screw of the fixing bolt 3. The aluminum alloy square gaskets 4 are respectively located on both sides of the metal base 2. Serrated surfaces 2d are respectively provided on the two side walls of the metal base 2. The end faces of the aluminum alloy square gaskets 4 are also provided with serrated surfaces that cooperate with the serrated surfaces 2d of the metal base 2. The screw of the fixing bolt 3 runs through the two aluminum alloy square gaskets 4, the waist-shaped hole 2a of the metal base 2 and the fixed keel 1 and the nut of the fixing bolt 3.

[0027] A first hook protrusion 2b and a second hook protrusion 2c extend from the end surface of the metal base 2 away from the building. The first hook protrusion 2b and the second hook protrusion 2c have the same shape and size. The first hook protrusion 2b and the second hook protrusion 2c are arranged at intervals, and the extension direction of the end of the first hook protrusion 2b is consistent with the extension direction of the end of the second hook protrusion 2c.

[0028] The photovoltaic panel fixed frame 5 is bonded to the edge of the back side of the solar photovoltaic panel 6. The photovoltaic panel fixed frame 5 is fixedly bonded to the back side of the solar photovoltaic panel 6 by silicone structural adhesive 5a and double-sided tape 5b. The photovoltaic panel fixed frame 5 is a special aluminum alloy frame (through-length bonding). The gap between two adjacent solar photovoltaic panels 6 is sealed by waterproof silicone weather-resistant sealant 6a.

[0029] Any two adjacent photovoltaic panel fixed frames 5 are respectively fixed to the first metal hanging weight 7 and the second metal hanging weight 8 by M5*12 countersunk screws 9 .

[0030] The first metal hanging weight 7 and the second metal hanging weight 8 are both specially made hanging weights of aluminum alloy. The first metal hanging weight 7 is provided with a first hook portion 7a and a first baffle portion 7b. The first hook portion 7a is located on the first metal hanging weight 7 close to one side of the building.
