Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, and in particular to a photovoltaic panel drainage channel anti-clogging and flow guiding structure. Background Technology

[0002] With the widespread application of photovoltaic power generation technology, photovoltaic panels are being installed and used extensively as a core component. In outdoor environments, water easily accumulates on the surface of photovoltaic panels. This water accumulation not only reduces the power generation efficiency of the panels but can also corrode the panel frames and internal circuits over time, shortening their lifespan. Therefore, drainage channels have become an indispensable part of photovoltaic panel installation, used to collect and guide rainwater from the panel surface.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: During long-term use, existing photovoltaic panel drainage channels are prone to the accumulation of debris such as leaves and sand carried by rainwater through the channels into the drainage pipe connected to the drainage outlet, resulting in blockage of the drainage pipe, poor drainage, and thus affecting the normal operation of the photovoltaic panels. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing photovoltaic panel drainage channels, during long-term use, allow rainwater carrying debris such as leaves and dust to accumulate in the drainage pipe connected to the drainage outlet, leading to blockage and poor drainage, which in turn affects the normal operation of the photovoltaic panel. To address this, we propose an anti-blockage and flow-guiding structure for photovoltaic panel drainage channels.

[0005] To achieve the above objectives, this application adopts the following technical solution: a photovoltaic panel drainage channel anti-clogging and flow guiding structure, comprising two photovoltaic panel bodies and a water guiding channel: a water guiding channel is installed on the side of the two photovoltaic panel bodies that are close to each other, and a drain pipe is connected to both sides of the water guiding channel. Two springs are fixedly connected to both sides of the inner wall of the water guiding channel, and a slide is fixedly connected to the other end of the two springs. The slide is slidably connected to the inner wall of the water guiding channel. Several filter holes are opened on the surface of the slide. A filter screen is slidably connected to the inner wall of the slide. Two mounting plates are fixedly connected to the surface of the filter screen. A square groove is opened on the side of the two mounting plates that are far from each other. Two arc-shaped plates are fixedly connected to the surface of the slide. A threaded rod is threaded into the arc-shaped plate. A square block is rotatably connected to one end of the threaded rod. The square block is slidably connected to the inner wall of the square groove. A rotating shaft is fixedly connected to the end of the threaded rod that is far from the square block.

[0006] Preferably, a limiting rod is slidably inserted inside the arc-shaped plate, and one end of the limiting rod is fixedly connected to the square block.

[0007] Preferably, a guide plate is fixedly connected to the inner wall of the water guide channel, and the guide plate is triangular in shape.

[0008] Preferably, the arc surface of the rotating shaft is provided with a number of strip grooves, and the number of strip grooves are evenly distributed in a circumferential array on the arc surface of the rotating shaft.

[0009] Preferably, ball bearings are fixedly connected to both sides of the slide, and two grooves are opened on the inner wall of the water guide channel, with the ball bearings slidingly connected to the inner wall of the groove.

[0010] Preferably, rubber strips are fixedly connected to both sides of the water guide channel, and the rubber strips are made of silicone rubber.

[0011] Preferably, the inner wall of the water guide channel is coated with an anti-corrosion coating, and the surface of the guide plate is coated with an anti-corrosion coating, which is a polyurethane coating.

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] Reference Figures 1-7As shown, this utility model provides a technical solution: a photovoltaic panel drainage channel anti-clogging and flow guiding structure, including two photovoltaic panel bodies 1 and a water guiding channel 2: the water guiding channel 2 is installed on one side of the two photovoltaic panel bodies 1 that are close to each other, and drain pipes 3 are connected to both sides of the water guiding channel 2. Two springs 4 are fixedly connected to both sides of the inner wall of the water guiding channel 2, and the other ends of the two springs 4 are fixedly connected to a slide 5. The slide 5 is slidably connected to the inner wall of the water guiding channel 2. A plurality of filter holes 7 are opened on the surface of the slide 5, and a filter screen 6 is slidably connected to the inner wall of the slide 5. The surface of the filter screen 6 is fixedly connected to... There are two mounting plates 8, and square grooves are opened on the side of the two mounting plates 8 that are far from each other. Two arc-shaped plates 9 are fixedly connected to the surface of the slide 5. A threaded rod 10 is inserted into the inner thread of the arc-shaped plate 9. A square block 13 is rotatably connected to one end of the threaded rod 10. The square block 13 is slidably connected to the inner wall of the square groove. A rotating shaft 11 is fixedly connected to the end of the threaded rod 10 that is far from the square block 13. Through the cooperation of the spring 4, the slide 5 and the filter screen 6, debris can be effectively intercepted from entering the drain pipe 3, so as to avoid the drain pipe 3 from being blocked and thus maintain the smooth flow of the drain trough and the drain pipe 3.The sliding connection between spring 4 and slide 5 adapts to dynamic changes and buffers external forces, improving structural stability and durability. The design of square block 13 and square groove makes the disassembly and maintenance of filter screen 6 simple and achieves efficient anti-clogging. A limiting rod 14 is slidably inserted in the arc plate 9. One end of the limiting rod 14 is fixedly connected to square block 13. The limiting rod 14 cooperates with arc plate 9 and square block 13 to limit the movement trajectory of square block 13 when the threaded rod 10 drives it to move, preventing square block 13 from shifting with the rotation of threaded rod 10. This ensures that square block 13 slides stably into or out of square groove, improving the reliability of structural connection and smooth operation during the disassembly and assembly of filter screen 6, and guiding water. A guide plate 15 is fixedly connected to the inner wall of the channel 2. The guide plate 15 is triangular in shape. The triangular guide plate 15 can divert and guide the water flow in the channel 2, optimize the water flow path, accelerate the water flow convergence and discharge speed, improve drainage efficiency, and at the same time reduce the turbulence and siltation of the water flow in the channel 2, reducing the risk of debris accumulation and blockage. Several strip grooves 12 are opened on the arc surface of the rotating shaft 11. The strip grooves 12 are evenly distributed in a circumferential array on the arc surface of the rotating shaft 11. The strip grooves 12 increase the friction of the arc surface of the rotating shaft 11, making it easier for the operator to rotate the rotating shaft 11 by hand. It is not easy to slip, and the rotation of the threaded rod 10 can be easily realized, allowing the filter screen 6 to be removed. The installation and fixing operation is more convenient and labor-saving, improving maintenance efficiency. Both sides of the slide 5 are fixedly connected with ball bearings 17. Two grooves 16 are opened on the inner wall of the water guide channel 2. The ball bearings 17 slide against the inner wall of the grooves 16. The cooperation between the ball bearings 17 and the grooves 16 converts the sliding friction between the slide 5 and the inner wall of the water guide channel 2 into rolling friction, effectively reducing friction and making the slide 5 slide more smoothly and flexibly under the action of the spring 4. This improves the buffering response to water flow impact and reduces wear. Both sides of the water guide channel 2 are fixedly connected with rubber strips 18. The rubber strips 18 are made of silicone rubber. The silicone rubber strips 18 utilize their high elasticity and softness to support the photovoltaic panel body. The rubber strip 18 acts as a buffer and self-adjusting element during installation with the water guide channel 2, effectively compensating for minor unevenness on the installation surface and ensuring a tight fit between the two. Simultaneously, the presence of the rubber strip 18 reduces hard contact between the photovoltaic panel 1 and the water guide channel 2 during installation. The inner wall of the water guide channel 2 is coated with an anti-corrosion coating, and the surface of the guide plate 15 is also coated with an anti-corrosion coating. This anti-corrosion coating is a polyurethane coating, which, with its excellent weather resistance, effectively resists outdoor ultraviolet rays, wind and rain erosion, and temperature changes, preventing the water guide channel 2 and guide plate 15 from rusting and corroding due to long-term exposure, thus extending the service life of the water guide channel 2 and guide plate 15.

[0025] Working principle: During use, rainwater flows into the drainage channel 2. The triangular guide plate 15 fixed to the inner wall of the drainage channel 2 can efficiently divert and guide the water flow, accelerate the convergence and discharge speed of the water flow, optimize the drainage path, reduce turbulence and siltation in the drainage channel 2, and reduce the risk of debris accumulation and blockage. The springs 4 on both sides of the inner wall of the drainage channel 2 are connected to the slide 5, allowing the slide 5 to slide flexibly in the drainage channel 2. The filter screen 6 fixed on the slide 5 plays a key role in intercepting debris such as leaves and sand in the rainwater and preventing them from entering the drain pipe 3 and causing blockage. The ball bearing 17 on the slide 5 cooperates with the groove 16 on the inner wall of the water guide trough 2 to convert sliding friction into rolling friction. This not only makes the slide 5 slide more smoothly and flexibly under the action of the spring 4, improving the buffer response to water flow impact, but also effectively reduces wear. When the filter screen 6 needs to be disassembled and replaced, the operator rotates the shaft 11 to drive the threaded rod 10 to rotate. The strip groove 12 on the arc surface of the shaft 11 increases the friction, making it easier for the operator to rotate the shaft 11 by hand, making the disassembly and fixing of the filter screen 6 more convenient and labor-saving. Then, the square block 13 connected to the threaded rod 10 is disengaged from the square groove on the mounting plate 8, so that the filter screen 6 can be easily disassembled. During this process, the limit rod 14 will restrict the movement trajectory of the square block 13 to ensure its stable movement and prevent it from deviating due to the rotation of the threaded rod 10, ensuring that the disassembly operation is carried out smoothly. During the installation of the photovoltaic panel body 1 and the water guide channel 2, the silicone rubber strips 18 on both sides of the water guide channel 2, with their high elasticity and flexibility, act as a buffer and self-adjusting element, closely fitting the photovoltaic panel body 1, compensating for minor unevenness of the installation surface, reducing hard contact between the two, and preventing rainwater leakage. Furthermore, the polyurethane anti-corrosion coating applied to the inner wall of the water guide channel 2 and the surface of the guide plate 15, with its excellent weather resistance, flexibility, and wear resistance, resists ultraviolet radiation, wind and rain erosion, and temperature changes in the outdoor environment, preventing the water guide channel 2 and guide plate 15 from rusting and corroding. This ensures the long-term stable operation of the entire structure and achieves efficient anti-clogging and water guiding functions.

Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
