Abstract
Description
Technical Field
[0001] This utility model relates to the field of roof skylight technology, and in particular to a waterproof structure for a photovoltaic roof pull-out skylight. Background Technology
[0002] A photovoltaic roof is a rooftop where solar power generation devices are installed. It uses solar photovoltaic technology to generate electricity in urban and rural buildings to achieve energy conservation and emission reduction goals. In practical applications, skylights are often needed to meet ventilation requirements. However, traditional skylight structures have poor waterproofing, and rainwater can easily enter the room through gaps in the window frame. Therefore, improvements are needed. Utility Model Content
[0003] Therefore, it is necessary to provide a photovoltaic roof pull-out skylight waterproof structure to address the problem that traditional skylight structures have poor waterproofing performance and rainwater can easily enter the room through the gaps at the edge of the window frame.
[0004] This utility model provides a waterproof structure for a photovoltaic roof pull-out skylight, comprising:
[0005] Support frame, fixed to the roof;
[0006] The photovoltaic panels are fixed to the surface of the support frame;
[0007] The window frame is fixed to the side wall of the support frame, and its height is less than the height of the support frame;
[0008] Glass window; sliding connection to the inner wall of the window frame;
[0009] A water barrier is used to prevent rainwater from entering the window frame and is fixed to the bottom of the photovoltaic panel;
[0010] The support frame and the window frame both have a sealing layer on their surfaces, and the side of the photovoltaic panel closest to the glass window is flush with the side of the window frame closest to the glass window.
[0011] In one embodiment, one side of the baffle extends to the support frame, and the other side of the baffle extends to the glass window.
[0012] In one embodiment, a positioning strip is provided in the middle of the water baffle, and the free end of the positioning strip is flush with the surface of the photovoltaic panel.
[0013] In one embodiment, water-limiting strips are symmetrically fixedly connected to the surface of the baffle, and a drainage ditch is formed between the water-limiting strips and the positioning strips.
[0014] In one embodiment, an insulation layer is provided between the support frame and the window frame.
[0015] In one embodiment, a distance screw is connected between the window frame and the support frame, and a surface positioning screw of the window frame abuts against the distance screw.
[0016] The aforementioned waterproof structure for photovoltaic roof pull-out skylights improves waterproofing by spraying a sealing layer onto the surfaces of the support frame and window frame, and adding a water-blocking plate between the photovoltaic panel and the window frame. Since the water-blocking plate can cover the window frame and the connection between the window frame and the glass window, it can effectively prevent rainwater from entering the room through the window frame, thus improving the waterproofing effect.

[0028] The following is combined with Figures 1-3 This invention describes a waterproof structure for a photovoltaic roof pull-out skylight.
[0029] like Figure 1 and Figure 2 As shown, in one embodiment, a photovoltaic roof pull-out skylight waterproof structure includes a support frame 100, a photovoltaic panel 200, a window frame 300, a glass window 400, and a water-blocking plate 500.
[0030] The support frame 100 is fixed to the roof and is used to fix the photovoltaic panels 200 on the roof.
[0031] The photovoltaic panel 200 is fixed to the surface of the support frame 100.
[0032] The window frame 300 is fixed to the side wall of the support frame 100, and the height of the window frame 300 is less than the height of the support frame 100. The window frame 300 is a pull-out window frame 300.
[0033] The glass window 400 is slidably connected to the inner wall of the window frame 300, and the glass window 400 is a pull-out window frame 300.
[0034] The water baffle 500 is used to prevent rainwater from entering the window frame 300, and the water baffle 500 is fixed to the bottom of the photovoltaic panel 200. The water baffle 500 is made of fiberglass material.
[0035] Both the support frame 100 and the window frame 300 have a sealing layer 310 on their surfaces, and the side of the photovoltaic panel 200 near the glass window 400 is flush with the side of the window frame 300 near the glass window 400.
[0036] The waterproof structure of this photovoltaic roof pull-out skylight is achieved by spraying a sealing layer 310 on the surface of the support frame 100 and the window frame 300, and adding a water baffle 500 between the photovoltaic panel 200 and the window frame 300. Since the water baffle 500 can cover the window frame 300 and the connection between the window frame 300 and the glass window 400, it can effectively prevent rainwater from entering the room from the window frame 300, thus improving the waterproof effect.
[0037] In this embodiment, one side of the water baffle 500 extends to the support frame 100, and the other side of the water baffle 500 extends to the glass window 400.
[0038] This allows the window frame 300 and the connection between the window frame 300 and the glass window 400 to be covered, reducing the amount of rainwater entering the room through the window frame 300.
[0039] In this embodiment, a positioning strip 510 is provided in the middle of the water baffle 500, and the free end of the positioning strip 510 is flush with the surface of the photovoltaic panel 200.
[0040] The positioning strip 510 can quickly locate the connection position between the water baffle 500 and the photovoltaic panel 200. The positioning strip 510 is located at the connection between the window frame 300 and the glass window 400, and the positioning strip 510 can fit against the side wall of the photovoltaic panel 200.
[0041] In this embodiment, see Figure 3 A water-limiting strip 530 is symmetrically fixedly connected to the surface of the water baffle 500, and a drainage ditch 520 is formed between the water-limiting strip 530 and the positioning strip 510.
[0042] The water-limiting strip 530 can block rainwater, thus facilitating the discharge of rainwater from the drainage ditch 520.
[0043] In this embodiment, an insulation layer 600 is provided between the support frame 100 and the window frame 300.
[0044] This facilitates improving the insulation effect at the connection between the support frame 100 and the window frame 300.
[0045] In this embodiment, a distance screw 700 is connected between the window frame 300 and the support frame 100, and a surface positioning screw 800 of the window frame 300 abuts against the distance screw 700, thereby facilitating the improvement of the stability of the connection between the window frame 300 and the support frame 100.
[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0047] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
