Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0039] Please refer to Figures 1-12 , the shown photovoltaic frame for rapid drainage, which includes a set of side frames 1, upper frames 2, lower frames 3 and connecting corner codes 4 with the same structure. Connecting cavities 5 for connecting with the connecting corner codes 4 are provided on the side frames 1, the upper frames 2 and the lower frames 3. A panel installation cavity 22 for installing a photovoltaic panel is provided on the upper frame 2. When installing the photovoltaic panel, the upper end of the photovoltaic panel is installed in the installation cavity 22. Specifically, when installing, gluing or setting a sealing strip to press against the photovoltaic panel can be selected for installation.

[0040] The upper frame 2 is provided with an inclined surface 6, and the lower end of the inclined surface 6 is close to the photovoltaic panel. The purpose of the inclined surface 6 provided on the upper frame 2 is mainly to quickly drain the rainwater on the inclined surface 6 to the photovoltaic panel when it rains. On the one hand, this can achieve the purpose of quickly draining the rainwater. On the other hand, the rainwater drained from the inclined surface 6 has a certain potential energy, which can play a role in flushing the surface of the photovoltaic panel, reducing the residue of dust on the photovoltaic surface after the rain dries. The included angle A between the inclined surface 6 on the upper frame 2 and the photovoltaic panel is designed between 25° and 35°.

[0041] The lower frame 3 is provided with a first lower end surface 7 and a first side end surface 8 for installing the photovoltaic panel. When installing the photovoltaic panel, the bottom end surface of the photovoltaic panel is installed on the first lower end surface 7, and the lower end surface of the photovoltaic panel abuts against the first side end surface 8. The height H of the first side end surface 8 is the same as the thickness of the photovoltaic panel to be installed. When installing the photovoltaic panel, its bottom end surface is fixedly installed on the first side end surface 8 and the first lower end surface 7 by means of adhesion. And the height H of the first side end surface 8 is designed according to the thickness of the photovoltaic panel to ensure that there is no height difference between the photovoltaic panel and the lower frame 3 after installation, that is, the upper surface of the photovoltaic panel after installation and the upper end surface of the body of the lower frame 3 are on the same horizontal plane. In this way, when the rainwater on the photovoltaic panel flows down and passes through the lower frame 3, there will be no blockage, so that the rainwater can be quickly drained away, and at the same time, it is not easy to deposit dust, thereby improving the power generation ability of the photovoltaic panel.

[0042] The side frame 1 is provided with a second lower end surface 9 and a second side end surface 10, and the height of the second side end surface 10 is the same as the height of the first side end surface 8. The body of the side frame 1 is also provided with a side boss 11 and a side water guiding surface 12. The side water guiding surface 12 is inclined, and the lower end of the side water guiding surface 12 is close to the photovoltaic panel. The included angle B between the water guiding surface 12 and the photovoltaic panel is designed between 15° and 25°.

[0043] A drainage component 13 is also provided on the side frame 1, and the drainage component 13 is movably arranged on the side frame 1. The connection method between the photovoltaic panel and the side frame 1 is actually the same as that of the lower frame 3. Specifically, it is connected to the second lower end face 9 and the second side end face 10 by gluing. And the height of the second side end face 10 is designed according to the thickness of the photovoltaic panel to ensure that after the photovoltaic panel is installed on the side frame 1, the upper end face of the photovoltaic panel is flush with the side edge of the side water diversion surface 12 on the side frame 1. Here, the side water diversion surface 12 is inclined, which can effectively drain the rainwater on the side water diversion surface 12 onto the photovoltaic panel. Utilizing the flow of rainwater, the photovoltaic panel is washed, and the dust on the photovoltaic panel is washed away to ensure the subsequent power generation capacity of the photovoltaic panel.

[0044] Specifically, the drainage component 13 includes a plurality of buckles 13a hung on the side boss 11, a connecting strip 13b, and a water diversion plate 13c. The connecting strip 13b is fixedly connected to the side edges of the plurality of buckles 13a. The water diversion plate 13c is inclined, with one end fixedly connected to the side surface of the connecting strip 13b and the other end inclined towards the lower frame 3. After the buckle 13a is sleeved on the side boss 11, the buckle 13a is further fixed to the side boss 11 by screws. The height of the water diversion plate 13c is less than the height of the connecting strip 13b. The included angle C between the water diversion plate 13c and the connecting strip 13b is designed to be between 30° and 50°.

[0045] In this implementation scheme, a drainage component 13 for quickly guiding rainwater is provided on the side frame 1. When it rains, the rainwater flowing through the side frame 1 is blocked by the water diversion plate 13c on the drainage component 13 from flowing directly away from the side frame 1. Instead, it flows in the direction of the photovoltaic panel through the guiding action of the water diversion plate 13c, achieving the purpose of washing the photovoltaic panel by borrowing the rainwater in the area of the frame 1. The dust, snow and other sundries deposited on the photovoltaic panel can be effectively washed down and flow away from the direction of the lower frame 3. Effectively ensure the cleanliness of the photovoltaic panel and the subsequent power generation capacity of the photovoltaic panel.

[0046] Specifically, a plurality of tiny grooves 14 are provided on both the first lower end face 7 and the first side end face 8 provided on the lower frame 3. The grooves 14 are also provided on the second lower end face 9 and the second side end face 10 on the side frame 1.

[0047] In this implementation scheme, when installing the photovoltaic panel, the firmness after the glue is connected to the first lower end face 7, the first side end face 8, the second lower end face 9 and the second side end face is improved by the provided tiny grooves 14. Simply put, by setting the tiny grooves 14, the surface roughness is increased to achieve the effect of improving the glue adhesion degree.

[0048] Specifically, a partition plate 15 is provided in the connection cavity 5, and the partition plate 15 divides the connection cavity 5 into an upper chamber 16 and a lower chamber 17. The connecting corner fitting 4 is provided with an upper connecting portion 18 and a lower connecting portion 19, and the upper connecting portion 18 is sleeved in the upper chamber 16, and the lower connecting portion 19 is sleeved in the lower chamber 17.

[0049] In this embodiment, the partition plate 15 divides the original integral connection cavity 5 into two parts, one part is the upper chamber 16 and the other part is the lower chamber 17, and the connecting corner fitting 4 is provided with an upper connecting portion 18 and a lower connecting portion 19 respectively corresponding to the upper chamber 16 and the lower chamber 17. The upper connecting portion 18 is connected to the upper chamber 16. Specifically, when connecting, the upper connecting portion 18 is provided with serrated protrusions that are engaged in the upper chamber 16. Similarly, the lower connecting portion 19 is also provided with serrated protrusions that are engaged in the lower chamber 17. The method of anchoring connection using serrated protrusions is a conventional technical means in the technical field, so it will not be described and shown in detail in this case. The simultaneous engagement of the two parts has better overall reliability compared to the traditional connection method where a single connecting corner fitting is directly connected to the frame. And when one of the two connecting portions fails to connect, there is still the other connecting portion for connection, reducing the risk of the frame becoming loose.

[0050] Specifically, an avoidance notch 20 is provided between the upper connecting portion 18 and the lower connecting portion 19, and the height of the avoidance notch 20 is greater than the thickness of the partition plate 15.

[0051] The avoidance notch 20 in this embodiment is designed to facilitate the installation of the entire connecting corner fitting 4.

[0052] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-restrictive.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.

[0053] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution.
