Description

Technical Field

[0001] This utility model relates to the field of rainwater drainage technology for photovoltaic panels, and in particular to a rainwater guide device for photovoltaic panels. Background Technology

[0002] With the surge in global demand for clean energy, the photovoltaic industry has experienced rapid development. Whether it's large-scale photovoltaic power plants or distributed rooftop photovoltaic systems, installed capacity continues to climb. However, the negative impact of rainwater on photovoltaic panels is becoming increasingly apparent. Rainwater flowing erratically on the surface of photovoltaic panels can seep into the panel frames and junction boxes, causing short circuits, corrosion, and other malfunctions.

[0003] Currently, some existing rainwater diversion devices on the market have relatively fixed structures, with limited dimensions and installation methods. They are difficult to effectively adapt to photovoltaic panels of different thicknesses. Traditional clip-on diversion devices use an integrated structure, which cannot adjust the tightness according to the actual thickness of the photovoltaic panel. Overly tight clips may cause compression damage to thinner photovoltaic panels, affecting the internal structure and power generation performance of the photovoltaic panel. Although some diversion devices can install photovoltaic panels of different thicknesses, they require the coordination of a series of parts to complete the installation, making the installation process cumbersome. Therefore, this application designs a photovoltaic panel rainwater diversion device to solve the above problems. Utility Model Content

[0008] Preferably, an abutment plate is fixedly connected to the two insertion posts, and a friction pad is provided on the top of the abutment plate.

[0009] Preferably, the friction pad is made of EVA anti-slip material, and the bottom surface of the friction pad is bonded to the abutment plate.

[0011] Preferably, the other end of the threaded rod is provided with a knob block for turning, and the knob block is polygonal in shape.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, the cooperation between the guide plate and the guide channel enables the orderly collection and directional discharge of rainwater, avoiding the disorderly flow of rainwater on the surface of the photovoltaic panel; the cooperation between the abutment component and the clamping plate enhances the stability of the connection between the guide and the photovoltaic panel, preventing the device from sliding; the threaded rod allows for precise adjustment of the abutment plate position according to the actual thickness of the photovoltaic panel, ensuring a firm installation without damaging the photovoltaic panel; and the telescopic column enables the guide to flexibly adapt to photovoltaic panels of different thicknesses, solving the problem that traditional guides cannot flexibly adjust the installation according to the thickness of the photovoltaic panel, and the differences exist in mixed installation scenarios of photovoltaic panels of different specifications.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example: See Figure 1-4 The photovoltaic panel rainwater guide of this utility model includes a guide plate 1 and a guide channel 5 opened at the bottom of the guide plate 1. The guide channel 5 facilitates the centralized and orderly discharge of rainwater, avoiding rainwater splashing everywhere and affecting the surrounding environment and equipment. A telescopic column 2 is fixed to one end of the bottom of the guide plate 1. The telescopic column 2 facilitates the adjustment of the height of the guide plate 1 to accommodate photovoltaic panels of different installation thicknesses. Multiple limiting holes are opened at equal intervals at the extended end of the telescopic column 2. A pin 3 for limiting is inserted into one of the limiting holes. The pin 3 facilitates the fixing of the telescopic column 2 at a specific telescopic length, improving the versatility and ease of installation of the guide. A clamping plate 4 is welded to one end of the telescopic column 2. Multiple water outlets 12 are opened on the clamping plate 4, and an abutment component is installed on the clamping plate 4.

[0021] In this invention, the abutment assembly includes two fixing blocks 6 symmetrically fixed to the top surface of the clamping plate 4. Each fixing block 6 has an insertion interface at its top, and each insertion interface contains a sliding insertion post 13. The fixing blocks 6 ensure the structural stability of the abutment assembly and provide reliable support for the normal operation of the abutment plate 11. The insertion interface is U-shaped, and its top is provided with a limiting plate to prevent the insertion post 13 from slipping. The insertion post 13 is inverted T-shaped, providing guidance and support for the movement of the abutment plate 11, ensuring that the abutment plate 11 can be stably and accurately adjusted in height. An abutment plate 11 is fixed to each of the two insertion posts 13, and the top of the abutment plate 11 is provided with a friction pad 10. The abutment plate 11 facilitates a tight and stable connection between the current guide and the photovoltaic panel, enhancing the installation of the current guide. Reliability is ensured, guaranteeing the proper functioning of the flow guide under various operating conditions. The friction pad 10 is made of EVA anti-slip material, and its bottom surface is bonded to the abutment plate 11. The friction pad 10 significantly improves the secure installation of the flow guide on the photovoltaic panel. The clamping plate 4 is threaded with a threaded rod 7 for adjusting the height of the abutment plate 11. An isolation sleeve 9 is provided at the connection between the threaded rod 7 and the abutment plate 11. One end of the threaded rod 7 is movably abutted against the bottom of the abutment plate 11. The threaded rod 7 facilitates precise adjustment of the abutment force of the abutment plate 11 on the photovoltaic panel, ensuring that the flow guide is securely installed and will not cause excessive pressure damage to the photovoltaic panel. The other end of the threaded rod 7 is provided with a knob block 8 for turning. The knob block 8 is polygonal in shape, which makes it easier and more convenient to adjust the threaded rod 7, thereby improving the ease of installation of the flow guide.

[0022] Working Principle: When using this invention, the operator first adjusts the length of the telescopic column 2 according to the installation height of the photovoltaic panel. By pulling out the pin 3, the telescopic column 2 is stretched or retracted to bring the guide plate 1 to the appropriate position. Then, the pin 3 is inserted into the corresponding limiting hole to fix the length of the telescopic column 2, completing the initial adjustment of the height of the guide plate 1. Next, the clamping plate 4 is placed on the edge of the photovoltaic panel, and the knob block 8 is rotated. The knob block 8 drives the threaded rod 7 to rotate. Since the threaded rod 7 is threadedly connected to the clamping plate 4, the rotation of the threaded rod 7 is converted into axial movement. One end of the threaded rod 7 moves against the bottom of the abutment plate 11, pushing the abutment plate 11 to move upward. The abutment plate 11 slides in the insertion interface of the fixing block 6 through the insertion post 13, gradually approaching the photovoltaic panel until the friction pad 10 is tightly against the surface of the photovoltaic panel, utilizing the high friction of the EVA anti-slip material. With the clamping plate 4, the rain guide is securely installed on the photovoltaic panel. Finally, when it rains, rainwater falls on the surface of the photovoltaic panel and flows downhill due to the tilt angle of the photovoltaic panel. The rain guide plate 1 catches the flowing rainwater and guides it into the guide channel 5. The guide channel 5 collects the rainwater and discharges it along a specific path, preventing rainwater from flowing disorderly on the surface of the photovoltaic panel, preventing rainwater from corroding the surrounding facilities of the photovoltaic panel, and preventing problems such as performance degradation of the photovoltaic panel due to water accumulation. In this process, the drain outlet 12 on the clamping plate 4 plays a role. A small amount of rainwater that seeps into the clamping part is discharged through the drain outlet 12, preventing water accumulation from corroding the edges of the photovoltaic panel. The isolation sleeve 9 is located at the connection between the threaded rod 7 and the abutment plate 11 to prevent direct contact between the two and cause wear and corrosion, ensuring the long-term stable operation of the adjustment mechanism. The use of the photovoltaic panel rainwater guide ends here.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
