[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0027] Example 1

[0028] like Figure 1 and Figure 4 As shown, the present invention provides a waterproof rubber strip 100 , comprising: an installation portion 110 and a working portion 120 arranged sequentially from top to bottom.

[0029] In this embodiment, first guide surfaces 111 are provided on both sides of the upper portion of the mounting portion 110, giving the upper portion of the mounting portion 110 a trapezoidal or triangular shape. The lower portion of the mounting portion 110 is symmetrically provided with first mounting grooves 113, with a deformation groove 112 provided between the two first mounting grooves 113. When the mounting portion 110 is installed in the second mounting groove 210 at the bottom of the frame bar 200, it serves as a guide, facilitating the rapid installation of the waterproof rubber strip 100 within the second mounting groove 210. If the stopper 211 engaged in the first mounting groove 113 is too long, it will squeeze the deformation groove 112, causing the sidewalls of the deformation groove 112 to bend inward, thus preventing the inner wall of the first mounting groove 113 from being squeezed over time, which would reduce its service life.

[0030] The working portion 120 includes a third waterproof strip 123, a first waterproof strip 121, and a second waterproof strip 122. The third waterproof strip 123 is disposed below one side of the mounting portion 110, and the second waterproof strip 122 is disposed below the other side of the mounting portion 110. The first waterproof strip 121 is fixed to the side of the second waterproof strip 122 away from the third waterproof strip 123. The third waterproof strip 123 and the second waterproof strip 122 are inclined toward each other, and the second waterproof strip 122 extends below the third waterproof strip 123, at least to the bottom of the third waterproof strip 123.

[0031] In this embodiment, the first waterproof strip 121 extends downward and away from the third waterproof strip 123, with the lowest point of the first waterproof strip 121 being lower than the lowest point of the third waterproof strip 123. The first waterproof strip 121, disposed externally, forms a first waterproof and windproof barrier, while also protecting the second waterproof strip 122 from rapid aging due to long-term exposure to wind, sun, and rain. The dual barriers of the first and second waterproof strips 121, 122 provide a waterproof and windproof barrier, effectively preventing rain and wind from entering the gaps between the photovoltaic tiles. Simultaneously, the support segment 220 can firmly press against the second waterproof strip 122, keeping it in close contact with the surface of the photovoltaic tile, enhancing its waterproof and windproof properties.

[0032] Example 2

[0033] like Figure 2 As shown, this embodiment differs from the first embodiment in that it further provides a photovoltaic module frame structure, including a waterproof adhesive strip 100 and a frame strip 200. The frame strip 200 has a second mounting groove 210 defined at its bottom, and the mounting portion 110 is mounted in the second mounting groove 210. Limiting blocks 211 are mounted on both side walls of the second mounting groove 210, and the limiting blocks 211 engage with the first mounting groove 113.

[0034] In this embodiment, the engagement of the stopper 211 with the first mounting groove 113 secures the waterproof strip 100, preventing it from falling out during transport of the photovoltaic panel 400. The waterproof strip 100 also provides scratch resistance. When squeezed, it can be partially embedded in the second mounting groove 210 while remaining partially exposed to cushion the tight contact between the frames. This prevents scratches caused by direct contact with the aluminum during installation, thus preserving the integrity and aesthetics of the photovoltaic tiles.

[0035] Example 3

[0036] like Figure 3 、 Figure 5 、 Figure 6 and Figure 7As shown, the difference between this embodiment and the first embodiment is that: a photovoltaic module waterproof system is further provided, comprising a frame formed by at least a front frame, a rear frame 300, a left frame 500 and a right frame 600, and a photovoltaic panel 400 mounted on the frame, and at least the front frame adopts a photovoltaic module frame structure;

[0037] When the upper and lower adjacent photovoltaic tiles are overlapped, the frame strip 200 of the upper photovoltaic tile is overlapped on top of the lower rear frame 300, the waterproof strip 100 abuts against the surface of the photovoltaic panel 400, and the rear frame 300 is set on the side close to the third waterproof strip 123, and the rear frame 300 abuts against the end of the frame strip 200.

[0038] A support section 220 is provided at the bottom of the frame bar 200, and the support section 220 abuts against the rear frame 300. The support section 220 extends upward from the side of the frame bar 200 to form a first water barrier 221. A second water barrier 310 is provided at the top of the rear frame 300. The second water barrier 310 is provided on the side of the first water barrier 221 away from the frame bar 200, and an arc-shaped guide surface 311 is provided on the side of the second water barrier 310 close to the first water barrier 221.

[0039] In this embodiment, the frame strip 200 is used in conjunction with the waterproof rubber strip 100 to form an effective barrier above the photovoltaic panel 400, preventing direct wind pressure from causing a large amount of water to flow into the back area of the photovoltaic panel 400. The second water retaining strip 310 has an arc-shaped guide surface 311 with an inward-bent structure, which cooperates with the first water retaining strip 221 to enhance the water-retaining effect, and can also effectively resist the direct attack of strong wind pressure, preventing rainwater from being directly guided to the top edge of the photovoltaic panel and seeping into the back of the photovoltaic panel 400.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
