[0078] The frameless photovoltaic structure includes a frameless photovoltaic panel 1, a profile frame 2 and a fixing member 3. The profile frame 2 is used to be installed and placed above a mounting bracket 4 to provide a certain support to the frameless photovoltaic panel 1, and the wiring of the frameless photovoltaic panel 1 can be arranged in the space of the profile frame 2. The fixing member 3 is fixed to the profile frame 2, and the fixing member 3 is used to fix the frameless photovoltaic panel 1 to the profile frame 2.

[0079] The profile frame 2 includes a first profile 21 and a second profile 22, and two first profiles 21 and two second profiles 22 are staggered to form a four-sided frame. Figure 2 The profile frame 2 is installed on the back side of the frameless photovoltaic panel 1, which is the side that does not receive solar radiation. The first profile 21 and the second profile 22 on the four sides of the profile frame 2 are all arranged near the edge of the frameless photovoltaic panel 1, but do not protrude from the edge of the frameless photovoltaic panel 1, thereby ensuring the frameless installation structure of the frameless photovoltaic panel 1.

[0080] like Figure 4 , 5 The fixing structure of the frameless photovoltaic panel 1 and the profile frame 2 is as follows: the fixing member 3 includes a first mounting portion 31 and a second mounting portion 32. The first mounting portion 31 is provided with a first slot 311 along the edge facing the frameless photovoltaic panel 1. The second mounting portion 32 is vertically arranged to fit the side of the second profile 22 of the profile frame 2. The second mounting portion 32 is provided with a screw hole and is locked on the second profile 22 by a fixing screw 34, so as to realize the fixed connection between the fixing member 3 and the second profile 22. The first slot 311 is provided with a protective pad 312. When the second mounting portion 32 is fixedly connected, the first slot 311 is clamped on the edge of the frameless photovoltaic panel 1, and forms a tight fit with the edge of the frameless photovoltaic panel 1 through the protective pad 312.

[0081] The protective pad 312 has two functions: first, it is used to realize the insertion between the first card slot 311 and the frameless photovoltaic panel 1, so that the first card slot 311 can firmly fix the frameless photovoltaic panel 1; second, the protective pad 312 can buffer the frameless photovoltaic panel 1 from friction damage caused by the first card slot 311 during installation. The first card slot 311 is set as a U-shaped slot, and the protective pad 312 is set as an L-shaped pad. The protective pad 312 is pressed on the front and side of the frameless photovoltaic panel 1 using an L-shaped structure.

The slot edge is larger than the slot edge on the back of the frameless photovoltaic panel 1, ensuring the firmness and stability of the frameless photovoltaic panel 1.

[0082] In order to realize the hidden frame installation structure of the frameless photovoltaic panel 1, only the fixing members 3 are arranged on the opposite sides of the frameless photovoltaic panel 1, such as Figure 6 The frameless photovoltaic panel 1 is clamped and installed using the fixing members 3 on both sides, and two fixing members 3 are set on a single side, and the fixing members 3 are installed at both ends close to the edge. In this way, in addition to the fixing members 3 on both sides, the frameless structure of the frameless photovoltaic panel 1 can be guaranteed, so that the frameless photovoltaic panel 1 can better utilize solar energy resources, improve photoelectric conversion efficiency and reduce production costs.

[0084] The mounting bracket 4 includes a transverse support rod 41 and a vertical support rod 42. A plurality of transverse support rods 41 and a plurality of vertical support rods 42 are staggered and arranged in a grid pattern, and one grid corresponds to a group of frameless photovoltaic structures.

The first mounting seat 421 is mounted on the second profile 22, and the second mounting seat 411 is mounted on the first profile 21. A first limiting device is arranged between the first mounting seat 421 and the second profile 22, and a second limiting device is arranged between the second mounting seat 411 and the first profile 21. The first limiting device and the second limiting device are used to complete the positioning and installation of the frameless photovoltaic structure on the mounting bracket 4.

[0085] like Fig.10 The first limiting device includes a first protruding side 423 of the first mounting seat 421 protruding upward, and a second protruding side 221 of the second profile 22 protruding downward.

During installation, the third card slot 211 is snapped into the corresponding third raised side 412.

[0087] The locking buckle 5 includes a lock core and a lock element. The lock core is arranged in the first mounting seat 421. The lock element is connected to the fixing element 3. When the frameless photovoltaic structure needs to be installed on the mounting bracket 4, the first mounting seat 421 is aligned with the second profile 22, and the first limiting device and the second limiting device are first positioned and installed.

A cavity 422 with an opening is arranged on the first mounting seat 421, and the nut 51 is placed in the cavity 422, and the nut 51 and the screw 52 are spirally connected through the opening. The bottom of the fixing member 3 is folded outward to form a folded edge 33, and the gasket is pressed on the folded edge 33. The screw 52 is screwed into the nut 51, and the gasket compacts the folded edge 33 so that the profile frame 2 is pressed against the first mounting seat 421, completing the installation and fixation of the frameless photovoltaic structure.

After the frameless photovoltaic structure is installed on the left and right sides of the first mounting seat 421, circular gaskets 53 are placed on the folded edges 33 of the two fixing members 3 on the two sides. There is a gap between the folded edges 33 of the two fixing members 3, and the gap corresponds to the screw hole of the circular gasket 53, which is used for the screw rod 52 to pass through. When the screw rod 52 and the nut 51 are spirally connected, the screw rod 52 continuously presses the circular gasket 53 downward, and the circular gasket 53 is continuously pressed on the two fixing members 3 until the screw rod 52 can no longer rotate downward.

The screw 52 passes through the gap between the two frameless photovoltaic structures and is screwed with the nut 51. The screw 52 continuously presses the round gasket 53 downward, and the round gasket 53 is continuously pressed on the two fixing members 3 until the screw 52 can no longer be rotated downward. At this time, the round gasket 53 is pressed on the two fixing members 3. The second profile 22 is pressed and fixed on the first mounting seat 421 by the pressing of the round gasket 53, and the fixing of the mounting bracket 4 and the frameless photovoltaic structure is realized under the mutual cooperation of the first limiting device, the second limiting device and the locking buckle 5.

[0102] Third embodiment

[0103] The third embodiment provides a rooftop 6 photovoltaic system, referring to Figure 18-25 .

[0104] The photovoltaic system on the roof 6 is a sloping roof structure, which is divided into a first sloping roof structure 61 and a second sloping roof structure 62. The mounting bracket 4 is installed on the first sloping roof structure 61 and the second sloping roof structure 62 respectively, and the mounting bracket 4 tilts the vertical support rod 42 according to the inclination of the sloping roof structure. After the mounting bracket 4 is installed, the frameless photovoltaic structure is installed by adding a buckle lock. The mounting bracket 4 is staggered with a plurality of horizontal support rods 41 and a plurality of vertical support rods 42 in a grid arrangement, and one grid corresponds to a group of frameless photovoltaic structures.

[0105] The photovoltaic system on the roof 6 involves the setting of a drainage system. A drainage groove 424 is set on the vertical support rod 42, and the corresponding drainage groove 424 is set on the first mounting seat 421. Fig. 9 .

[0106] like Fig.24 , 25 The photovoltaic system on the roof 6 involves the setting of a waterproof structure 7, which is mainly set for the top of the roof 6. The waterproof structure 7 is set as an umbrella structure, which includes an umbrella handle 71 and an umbrella part 72. The bottom of the umbrella handle 71 is provided with an umbrella seat 73, and the umbrella part 72 is bent downward to form an umbrella edge 74.

[0107] During installation, the umbrella handle 71 of the waterproof structure 7 is inserted into the top gap of the roof 6, which is the interval between the first sloping roof structure 61 and the second sloping roof structure 62, where the frameless photovoltaic structures are installed at the highest positions. The umbrella seat 73 limits the waterproof structure 7 from pulling out the umbrella handle 71, and the umbrella edge 74 rests against the upper surface of the frameless photovoltaic structure installed at the highest position and is fixed by glass glue.

[0108] like Fig.23 In order to match the tilted setting of the roof 6, the third raised side 412 on the front of the second mounting seat 411 is a low-position raised side 413, and the third raised side 412 on the rear is a high-position raised side 414, and the high-position raised side 414 is higher than the low-position raised side. Through the high and low position settings on the second mounting seat 411, when installing the frameless photovoltaic structure, from the high position to the low position, the edge of the frameless photovoltaic structure on the high position will press on the edge of the frameless photovoltaic structure on the low position, forming a layered overlapping structure. In terms of waterproofing, this structure will flow from the high position to the low position, and the overlapping position can play a waterproof effect to prevent water from penetrating.

[0109] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
