Description

Technical Field

[0001] This utility model relates to the field of solar photovoltaic power generation system technology, and in particular to a dynamic load anti-loosening drainage device for photovoltaic module arrays. Background Technology

[0002] A photovoltaic (PV) panel is a power generation device that produces direct current (DC) electricity when exposed to sunlight. It consists of thin, solid-state photovoltaic cells made almost entirely of semiconductor materials (such as silicon). Water and dust often accumulate at the bottom of PV panels, severely impacting their power generation efficiency. Statistics show that water and dust accumulation directly reduces PV panel power generation by more than 30%. The vibrations generated by cleaning robots when cleaning PV panels can cause the fastening bolts to loosen, leading to the PV panels sliding downwards. This sliding can then affect the cleaning robot's movement and cause malfunctions. While some devices exist for cleaning PV equipment, these devices are often complex and significantly increase costs. Chinese invention patent CN109617520A discloses a drainage device for PV panels. While the device has a relatively simple structure, it cannot secure the PV panels. The vibrations from the cleaning robot can cause the panels to loosen, and its irregular structure, with a flared opening, hinders the cleaning robot's cleaning process.

[0003] To address this issue, this application presents a dynamic load anti-loosening and drainage device for photovoltaic module arrays. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, this utility model provides a dynamic load anti-loosening and drainage device for photovoltaic module arrays.

[0005] A dynamic load anti-loosening and drainage device for photovoltaic module arrays, comprising anti-loosening and drainage components, characterized in that:

[0006] The anti-loosening drainage component is installed between two adjacent photovoltaic panels. The upper and lower C-shaped slots of the anti-loosening drainage component correspond to the glass front frame and the glass back frame of the two photovoltaic panels, respectively. Then, the internal hexagonal head bolts pass through the pressure plate and are tightly connected to the anti-loosening drainage component, which plays a role in preventing loosening and draining the photovoltaic panels under dynamic load.

[0007] Furthermore, in order to better realize this utility model, the anti-loosening drainage component is made of aluminum alloy integral casting and precision machining, and includes four upper C-shaped clamping plates, two lower C-shaped clamping plates, a vertical plate and a middle isolation column.

[0008] Furthermore, in order to better realize this utility model, the upper C-shaped card plate of the anti-loosening drainage component is provided with anti-slip grooves, and the inner width of the upper C-shaped card plate is equal to the size of the aluminum frame of the photovoltaic panel glass surface.

[0009] Furthermore, in order to better realize this utility model, the inner width of the lower C-shaped card plate of the anti-loosening drainage component is equal to the size of the aluminum frame on the back of the photovoltaic panel glass.

[0010] Furthermore, in order to better realize this utility model, the upright plate of the anti-loosening drainage component has two drainage grooves. When it rains or the photovoltaic panel is washed with water, the drainage grooves can drain the sewage and mud accumulated in the lower corner of the photovoltaic panel.

[0011] Furthermore, in order to better realize this utility model, the intermediate isolation column of the anti-loosening drainage component is machined with an M8 threaded through hole, and the thickness of the intermediate isolation column is equal to the gap between two adjacent photovoltaic panels.

[0012] The beneficial effects of this utility model are:

[0013] This device is installed between the lower, inclined edges of two adjacent photovoltaic panels. During installation, simply clamp the bottom of the dynamic load anti-loosening device onto the back frame of the module, then gently press down to achieve a seamless fit with the photovoltaic module. The device features special anti-slip grooves, ensuring a firm grip on the photovoltaic module frame and locking the module in place. Made of aluminum alloy, this dynamic load anti-loosening drainage device is easy to install, precisely sized for a seamless fit with the photovoltaic module, and securely locks the module in place. It also features two drainage channels. When rainwater flows down the surface of the photovoltaic module, it washes away surface dust, which then drains through the channels to the outside of the module, effectively removing accumulated water and dust. A water-absorbing drainage and mud-removing adhesive can also be added to the drainage channels for even better drainage and dust removal. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] Figures 1-8 This is a specific embodiment of the present invention, which is a dynamic load anti-loosening and drainage device for photovoltaic module arrays, implemented in the following manner:

[0027] The thickness of the intermediate isolation column of the anti-loosening drainage component is equal to the gap between two adjacent photovoltaic panels. Therefore, by inserting the intermediate isolation column of the anti-loosening drainage component between two photovoltaic panels, the longitudinal displacement and sliding of the module can be prevented.

[0028] The lower C-shaped clamp of the anti-loosening drainage component first engages with the aluminum frame on the back of the photovoltaic module's glass. Because its inner width is equal to the size of the aluminum frame on the back of the photovoltaic module's glass, the anti-loosening drainage component is firmly secured to the aluminum frame. Then, the upper C-shaped clamp of the anti-loosening drainage component engages with the aluminum frame on the glass side of the photovoltaic panel. Because its inner side has anti-slip grooves with a width equal to the size of the aluminum frame on the glass side of the photovoltaic panel, and the vertical height of the anti-loosening drainage component is equal to the thickness of the photovoltaic panel, the anti-loosening drainage component is tightly secured to the photovoltaic panel, thus restricting vertical displacement between the photovoltaic panels.

[0029] Finally, an M8X50 hex bolt is used to tightly connect the anti-loosening drainage component to the threaded middle isolation column of the pressure plate. With the anti-loosening drainage component at the bottom, the photovoltaic module sandwiched in the middle, and the pressure plate on top, all adjacent photovoltaic panels are connected together in sequence. This completely restricts the bidirectional displacement of the entire row of photovoltaic modules, so that even if the cleaning robot runs over it and vibrates, the photovoltaic panels will not become loose.

[0030] The drainage function in this embodiment is implemented as follows: two drainage channels are opened on the upright plate. When it rains or the photovoltaic modules are washed with water, the drainage channels can drain the sewage and silt accumulated in the lower corner of the photovoltaic modules.

[0031] This embodiment includes an auxiliary fixing component, the structure of which is as follows: Figure 6 and Figure 7 As shown, it includes a second pressure plate and a support plate. The second pressure plate has a first through hole, and the support plate has a second through hole that matches the first through hole. Fixing bolts are installed in the first and second through holes, and nuts are installed on the fixing bolts. The nuts are located on the side of the support plate away from the pressure plate.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
