[0024] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0025] Example 1

[0026] like Figure 1 As shown, this embodiment provides a dustproof frame, which is used to install a laminate 4. The dustproof frame is composed of a base 1, a support part 2 and a filling part 3, and the base 1, the support part 2 and the filling part 3 are arranged in an S shape. The base 1 is used to support the components above it, and the laminate 4 can be placed on the support part 2, and the support part 2 and the filling part 3 are used to connect with the laminate 4.

[0027] Specifically, the base 1 is located at the bottom of the dustproof frame, which is composed of a whole plate. An n-shaped support portion 2 is arranged on the top of the base 1. The support portion 2 is used to support the laminate 4. A filling portion 3 is arranged on one side of the support portion 2 close to the edge of the laminate 4. The filling portion 3 is a C-shaped structure, which can effectively limit the installation position of the laminate 4. In this embodiment, the laminate 4 is mainly composed of a front cover plate, a rear cover plate, a packaging film and a battery string. Among them, the battery string is located in the middle, and the front cover plate and the rear cover plate are respectively placed on the upper and lower surfaces of the battery string. The battery string is sealed with the front cover plate and the rear cover plate by a packaging film.

[0028] The bottom surface of the laminate 4 is opposite to the top surface of the support part 2, and the side surface of the laminate 4 is opposite to the side surface of the filling part 3. The laminate 4 can be fixedly connected with the support part 2 and the filling part 3 by adhesive. The adhesive can be realized by conventional glue, which is not specifically limited in this embodiment.

[0029] When the laminate 4 is fixed on the support part 2 and the filling part 3, the top surface of the laminate 4 is located between the outer top surface A and the inner top surface B of the filling part 3, that is, the side surface of the top of the filling part 3 limits the movement range of the laminate 4. A first inclined surface 8 is provided on the side of the outer top surface A of the filling part 3 close to the laminate 4. The height of the first inclined surface 8 gradually increases from the side close to the laminate 4 to the side away from the laminate 4, so that the first inclined surface 8 forms a certain angle with the horizontal plane. The lower edge of the first inclined surface 8 is not higher than the upper surface of the laminate 4.

[0030] When the laminate 4 is installed at an angle, the first inclined surface 8 tends to be horizontal, so that rainwater flows away along the first inclined surface 8 after fully washing the surface of the laminate 4. A very small amount of rainwater and dust in the rainwater can be deposited on the surface of the first inclined surface 8, thereby reducing the risk of dust deposition on the surface of the laminate 4.

[0031] In some optional embodiments, the outer top surface A of the filling portion 3 is slightly higher than the top surface of the laminate 4 by 1 mm to 2 mm, but not too much higher to avoid accumulation of debris at the connection between the filling portion 3 and the laminate 4.

[0032] In some optional embodiments, for most areas, the sun is usually biased towards the south. When installing the laminate 4, in order to make the laminate 4 face the direction of the sun, it needs to be installed at an angle. Therefore, in this embodiment, when the laminate 4 is installed at an angle, it is necessary to make the first inclined surface 8 as close to the horizontal plane as possible so that rainwater can flow along the first inclined surface 8. Generally speaking, the laminate 4 is installed at an angle of 5° to 15°. Therefore, when the laminate 4 is in a horizontal position, the first inclined surface 8 of this embodiment has an angle of 5° to 15° with the horizontal plane, which can meet the conventional installation requirements.

[0033] In some optional embodiments, a groove 5 is provided on the top surface of the support portion 2. When the laminate 4 and the support portion 2 are fixed by adhesive, the adhesive is squeezed and stored in the groove 5. A protrusion 6 is provided inside the groove 5, and the protrusion 6 can increase the contact area between the top surface of the support portion 2 and the adhesive, thereby increasing the bonding strength between the support portion 2 and the adhesive. In addition, in order to more effectively achieve the above effect, there can be multiple protrusions 6, and they are arranged in the groove 5 in a parallel distribution.

[0034] In some optional embodiments, a transverse groove 7 is further provided below the inner top surface B of the filling portion 3. When the laminate 4 and the filling portion 3 are fixed by adhesive, the adhesive moves upward due to being squeezed. When the adhesive moves upward, the adhesive can be stored in the transverse groove 7, thereby reducing the risk of overflowing to the surface of the laminate 4.

[0035] Example 2

[0036] like Figures 2 to 4 As shown, this embodiment provides a photovoltaic module installation fixture. The photovoltaic module installation fixture is used to fix the dustproof frame on the external fixing body 16, so as to achieve the installation and fixation of the photovoltaic module. The photovoltaic module installation fixture is adapted to the contour of the contact part of the dustproof frame.

[0037] Specifically, the specific structure of the dustproof frame can refer to the content described in Example 1, and this embodiment will not be repeated here. The photovoltaic module mounting fixture can be fixedly connected to the dustproof frame. The photovoltaic module mounting fixture is composed of a fixing portion 11 and a clamping portion 12. The fixing portion 11 is n-shaped. The fixing portion 11 can be fixedly connected to the support portion 2 of the dustproof frame through a first connecting member 13, and fixedly connected to the external fixing body 16 through a second connecting member 15.

[0038] A clamping portion 12 is provided on the top of the fixing portion 11. The clamping portion 12 extends upward and is bent outward at its top to form a bent portion. When the photovoltaic module mounting fixture is fixedly connected to the dustproof frame, the filling portion 3 of the dustproof frame can be embedded in the bent portion of the photovoltaic module mounting fixture. In addition, a second inclined surface 14 that cooperates and contacts with the first inclined surface 8 on the dustproof frame is provided on the inner top surface B of the bent portion. In this embodiment, it is only necessary to change the shape of the clamping portion 12 of the photovoltaic module mounting fixture to match the S-shaped dustproof frame proposed in Example 1. Of course, for dustproof frames of other shapes, this embodiment can also enable the photovoltaic module mounting fixture to adapt to dustproof frames of different shapes by changing the shape of the clamping portion 12.

[0039] In some optional embodiments, a transverse connecting through hole 9 is provided on the support portion 2 of the dustproof frame. The first connecting member 13 can fix the dustproof frame and the photovoltaic module mounting fixture through the transverse connecting through hole 9. Among them, an optional structure of the first connecting member 13 can be a threaded connection structure of a screw and a nut. Specifically, the screw can be transversely fixed on the fixing portion 11 of the photovoltaic module mounting fixture. When the dustproof frame is fixedly connected to the photovoltaic module mounting fixture, the screw can be first passed through the transverse connecting through hole 9, and then the dustproof frame and the photovoltaic module mounting fixture are locked through the threaded connection between the nut and the screw.

[0040] In some optional embodiments, a longitudinal connection through hole is provided on the fixing portion 11 of the photovoltaic module mounting fixture. The second connecting member 15 can be used to fix the photovoltaic module mounting fixture to the external fixing body 16 through the longitudinal connection through hole. An optional structure of the second connecting member 15 can be a bolt. The bolt can pass through the longitudinal connection through hole to fix the photovoltaic module mounting fixture to the external fixing body 16.

[0041] In some optional embodiments, the base 1 of the dustproof frame extends beyond the support portion 2 in a direction away from the laminate, and a bending structure 10 is formed by protruding upward at the end of the portion that exceeds the support portion 2. The fixing portion 11 of the photovoltaic module mounting fixture abuts against the base 1 of the dustproof frame and cooperates with the bending structure 10 to form a snap-on contact, so that when the photovoltaic module is deformed by snowstorms or windstorms, a reaction force is brought about, deformation is reduced, and the risk of the laminate 4 being detached is reduced.

[0042] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
