[0019] like Figure 1 The photovoltaic roof water surface installation device of the present invention is shown, including a roof panel 1 and a photovoltaic bracket 2. The top of the roof panel 1 is provided with a plurality of mutually parallel ridges 11. The photovoltaic bracket 2 is fixedly mounted above the ridges 11 by a plurality of adapter clamps 3. A plurality of photovoltaic panels are provided on the photovoltaic bracket 2. The plurality of photovoltaic panels are arranged along the length direction of the photovoltaic bracket 2. Adjacent photovoltaic panels are connected by a first locking device 4. The outer sides of the photovoltaic panels at the head end and the tail end are fixedly connected to the photovoltaic bracket 2 by a second locking device 5. Figure 1 The figure only shows the connection status of three photovoltaic panels. In actual use, the number of photovoltaic panels can be adjusted as needed. Figure 1 This is only a schematic diagram and is not intended to be limiting.

[0020] like Figure 2 As shown, in this embodiment, the roof panel 1 adopts a metal-surface polyurethane composite panel, and a plurality of mutually parallel ridges 11 are provided on the top of the roof panel 1. General metal roof panels such as color-coated steel or other non-metallic materials can also be used as the material of the roof panel, and there is no limitation here. The photovoltaic bracket 2 includes a bottom support 21, and a vertical support 22 is vertically arranged above the bottom support 21. The vertical support 22 is fixedly connected with an oblique support 23, and the oblique support 23 is fixedly connected with a main beam 24. The photovoltaic bracket 2 belongs to the prior art, and its bottom is used to connect with the roof panel 1, and a photovoltaic panel is installed on its top.

[0021] The photovoltaic bracket 2 is fixedly mounted on the top of the convex ridge 11 through a plurality of adapter clamps 3. Figure 3 As shown, the adapter clamp 3 includes a first clamp 31 and a second clamp 32, and the second clamp 32 is rotatably connected to the first clamp 31. The first clamp 31 and the second clamp 32 are respectively arranged on both sides of the convex ridge 11 and are clamped or loosened with the convex ridge 11 through a first spring 33. One end of the first spring 33 is fixedly connected to the first clamp 31, and the other end of the first spring 33 is fixedly connected to the second clamp 32.

[0022] Specifically, the first clamp 31 includes a horizontally arranged fixed plate 311, the two ends of the fixed plate 311 are bent downward to form a first vertical plate 312 and a second vertical plate 313, the bottom of the first vertical plate 312 is connected to a first clamping plate 314, and the two ends of the second vertical plate 313 are symmetrically provided with horizontal rotating shafts 315.

The size of the clearance groove is larger than that of the second vertical plate 313, and there is a certain distance between the top of the third vertical plate 321 and the bottom of the fixed plate 311, so that when the second clamp 32 rotates around the rotating shaft 315 with the first clamp 31, there is no interference between the third vertical plate 321 and the second vertical plate 313 and the fixed plate 311. Preferably, there are two first springs 33, and the two first springs 33 are arranged along the length direction of the fixed plate 311. One end of the first spring 33 is fixedly connected to the inner side wall of the first vertical plate 312, and the other end is fixedly connected to the inner side wall of the third vertical plate 321. Under normal conditions, due to the elastic effect of the first spring 33, the first clamp 31 and the second clamp 32 are in a state of being close to each other and relatively closed.

The tops of the two second flanges 422 are fixedly connected with a cover plate 424 to protect the first locking device 4 below to prevent rainwater and dust from entering. The groove formed between the two second flanges 422 allows the first flange 412 to pass through, and each second flange 422 is slidably provided with a clamping column 423, which is engaged or separated with the clamping slot 4121. Specifically, mounting holes are provided on the opposite sides of the two second flanges 422, and a second spring (not shown in the figure) is provided in the mounting hole. One end of the second spring is fixedly connected to the bottom wall of the mounting hole, and the other end is fixedly connected to the fixed end of the clamping column 423.

The first base 431 is inserted into the inner cavity of the main beam 24 and slides along its length. The shape and size of the first base 431 are matched with the shape and size of the inner cavity of the main beam 24 to play a guiding and limiting role at the same time. A first top plate 432 is provided on the top of the first base 431, and the two ends of the first top plate 432 are bent upward to form a first crimping portion 433.

Figure 7 As shown, the second locking device 5 includes a second base 51, which is slidably connected to the main beam 24 of the photovoltaic bracket 2. The second base 51 has the same structure as the first base 431, and is both inserted into the inner cavity of the main beam 24 and slides along its length direction.

[0027] When the photovoltaic roof water surface installation device of the present invention is used, the roof panel 1 is first laid and fixed on the existing roof, and then the bottom support 21 of the photovoltaic bracket 2 is fixedly connected to the top of the fixing plate 311 of the adapter clamp 3, and the second clamp 32 is dragged outward to rotate around the rotating shaft 315 in the direction away from the first clamp 31, and the first spring 33 is stretched, and the first clamp 31 and the second clamp 32 are relatively opened, so that the inner side walls of the first clamping plate 314 and the second clamping plate 322 are in contact with the outer side walls of the ridge 11, and then the second clamp 32 is released, and when the first spring 33 is reset, it shrinks and drives the second clamp 32 to move closer to the first clamp 31. Rotate, and then under the joint action of the first clamp 31 and the second clamp 32, the adapter clamp 3 is tightly clamped on the outer side of the convex ridge 11; then place the first-end photovoltaic panel 6 on the photovoltaic bracket 2, and slide the second locking device 5 along the main beam 24, so that the side wall of the second crimping portion 53 abuts against the side wall of the first-end photovoltaic panel 6, and the top wall of the second crimping portion 53 abuts against the top of the first-end photovoltaic panel 6, and then rotate the bolt 435 to make the free end of the bolt 435 abut against the outer side wall of the main beam 24, thereby pressing and fixing the outer side wall of the first-end photovoltaic panel 6; place the first intermediate photovoltaic panel 8 on the right side of the first-end photovoltaic panel 6, and move it to the left along the length direction of the photovoltaic bracket 2 When the clamping column 423 on the second locking block 42 contacts the first flange 412 on the first locking block 41, the second spring is compressed, and the two clamping columns 423 shrink away from the first flange 412 under the pressure of the first flange 412, and the middle photovoltaic panel 8 continues to move to the left until the clamping column 423 moves to the clamping groove 4121, and the second spring resets and stretches, so that the clamping column 423 is clamped with the clamping groove 4121 and plays a role of limiting in the X direction, and the middle photovoltaic panel 8 no longer moves to the left, so that the first end photovoltaic panel 6 and the first middle photovoltaic panel 8 are tightly connected.
