[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please refer to Figures 1-4 , Figure 1 A front view structural schematic diagram of an embodiment of the photovoltaic module support system based on flexible duct wind energy self-cleaning provided by this utility model; Figure 2 for Figure 1 A partial structural diagram of the air guide duct in the middle; Figure 3 A schematic diagram of the flexible sleeve connector connection structure in one embodiment of the photovoltaic module support system based on flexible duct wind energy self-cleaning provided by this utility model; Figure 4 This is a schematic diagram of the structure of the wind-collecting baffle after it is closed in one embodiment of the photovoltaic module support system based on flexible duct wind energy self-cleaning provided by this utility model.

[0027] In one specific embodiment, the photovoltaic module support system based on flexible duct wind energy self-cleaning includes an air guide trough 20, an air receiving baffle 30, and a flexible duct 40. The air guide trough 20 is installed on the photovoltaic support 10 and is used to change the direction of the wind received on the wind-receiving surface through the trough structure. Photovoltaic modules are installed on the photovoltaic support 10. The flexible duct 40 is provided with multiple ventilation holes and is disposed on the photovoltaic modules. The air receiving baffle 30 is installed on the photovoltaic support 10 and is located at the wind-receiving end of the air guide trough 20. It is used to block the wind received by the air guide trough 20 and guide it to the inlet of the flexible duct 40, and output it from the ventilation holes, thereby realizing a purging operation on the surface of the photovoltaic modules installed on the photovoltaic support 10.

[0028] By installing the air guide duct 20 on the photovoltaic support 10, the airflow direction received by the wind-receiving surface is changed through the duct structure, and the air is guided to the flexible duct 40 by the wind-collecting baffle 30 and output from the vent. This achieves a blowing operation on the surface of the photovoltaic modules installed on the photovoltaic support 10, enabling directional cleaning of the modules, automatically removing dust and fallen leaves from the surface of the photovoltaic modules, and solving the problem of power generation loss caused by dust accumulation. Through real-time cleaning, dust obstruction is reduced, improving module efficiency; it relies entirely on natural wind, with no additional energy consumption; the structure is simple, reducing manual maintenance costs throughout its lifespan; the flexible duct 40 can adapt to different inclination angles and terrains, making it suitable for scenarios prone to dust accumulation such as deserts and farmland.

[0029] Directly connecting the flexible duct 40 to the air guide trough 20 would increase the difficulty of the connection, and there are certain limitations on the positions of the air guide trough 20 and the flexible duct 40, otherwise it would be wasteful. To improve the ease of connection, in one embodiment, the photovoltaic module support system based on the flexible duct 40 wind energy self-cleaning further includes a flexible sleeve connector 50 disposed between the flexible duct 40 and the air guide trough 20, for guiding the air received by the air guide trough 20 into the flexible duct 40.

[0030] By incorporating the flexible sleeve connector 50, the positions of the air guide duct 20 and the flexible pipe 40 are no longer restricted, improving the convenience and efficiency of the connection. Furthermore, there are no limitations on the interface between the two, allowing for the connection of air guide ducts 20 and flexible pipes 40 of different models, thus increasing connection flexibility. This application does not limit the shape, size, material, or connection method of the flexible sleeve connector 50.

[0031] In one embodiment, the flexible sleeve connector 50 and the air guide groove 20 are connected and fixed by bolts located on both sides of the flexible sleeve connector 50.

[0032] The flexible sleeve connector 50 and the air guide trough 20 are fixed by bolts on both sides of the flexible sleeve connector 50, eliminating the need to directly install bolts or other connectors on the two, and eliminating the need for processing and pre-reservation of connection positions, thereby improving the structural strength of the two and the efficiency of installation.

[0033] In this application, the flexible pipe 40 is disposed on the photovoltaic module to purge the solar cells. In order to improve the reliability of the connection and avoid vibration during purging, which would reduce the reliability of operation, in one embodiment, the lower side of the flexible pipe 40 is fixedly connected to the photovoltaic module by structural adhesive.

[0034] When the flexible pipe 40 is placed between the components, the gap between the lower side of the flexible pipe 40 and the component is fixed with structural adhesive. This prevents the flexible pipe 40 from shaking and also helps with waterproofing, preventing rainwater from falling onto the house through the gap.

[0035] In this application, the size and direction of the through hole of the flexible pipe 40 are not limited. Generally, in order to improve the purging range and efficiency, the circumferential direction of the vent hole is at an angle of 15°-45° with the surface of the photovoltaic module.

[0036] Preferably, the plurality of vent holes are of equal size and shape, and are evenly distributed along the axial direction of the flexible pipe 40, with the hole spacing being 5-8 times the hole diameter.

[0037] The vent holes in this application can be single-layer holes or multi-layer holes to achieve cleaning of different locations, and the vent hole sizes can be the same or different.

[0038] This application does not impose any limitations on the size, spacing, etc. of the vent holes.

[0039] Due to the different sources of wind direction, in order to improve cleaning efficiency and avoid excessively weak or strong winds during cleaning, in one embodiment, the photovoltaic module support system based on flexible duct 40 wind energy self-cleaning also includes an adjustment component disposed between the photovoltaic support 10 and the air guide duct 20, which is used to adjust the angle between the photovoltaic support 10 and the air guide duct 20 by adjusting the length of the adjustment component.

[0040] By setting an adjustment component between the photovoltaic bracket 10 and the air guide trough 20, the angle between the photovoltaic bracket 10 and the air guide trough 20 can be adjusted by adjusting the length of the adjustment component. This allows the air guide trough 20 to face the wind direction directly when the external wind force is too small, maximizing the air intake. If the wind force is too strong, far exceeding the cleaning requirements, the angle between the air guide trough 20 and the wind direction can be reduced to decrease the amount of air entering the air guide trough 20, thereby reducing the cleaning wind force, improving the efficiency and safety of cleaning, and reducing damage to the components.

[0041] During periods of high wind and sand, purging is not required, but the air guide duct 20 will continue to collect wind. If purging continues at this time, the accelerated sand and dust will damage the surface of the components.

[0042] To address the aforementioned technical issues, in one embodiment, the photovoltaic module support system based on the flexible duct 40 for wind energy self-cleaning further includes an inlet shielding plate disposed at the inlet of the flexible duct 40 and an outer wall shielding plate disposed on the outer wall of the flexible duct 40. The inlet shielding plate is movably connected to the inlet of the flexible duct 40 to enable or disable air intake at the inlet of the flexible duct 40. The outer wall shielding plate has the same shape as the outer wall of the flexible duct 40 and is used to open or close the vent by sliding along a slide rail parallel to the axis of the flexible duct 40.

[0043] By installing an inlet baffle and an outer wall baffle on the flexible duct 40, the flexible duct 40 can be closed when purging is not required, thus isolating it from the outside world, preventing dust from entering, and potentially preventing damage to the component surface from continued purging, thereby improving the safety and reliability of use.

[0044] In this application, the connection position and method between the air guide trough 20 and the photovoltaic bracket 10 are not limited. They can be connected by bolts, hinges, or snap-fits. In one embodiment, the air guide trough 20 and the inclined beam of the photovoltaic bracket 10 are connected by a hinge.

[0045] The hinged connection to the inclined beam of the photovoltaic bracket 10 can improve the introduction of wind from all directions and improve the efficiency of installation.

[0046] In order to reduce the interference of the cleaning device on the power generation of the components, in one embodiment, the air guide trough 20 is a light-transmitting air guide trough 20, the air collection baffle 30 is a light-transmitting air collection baffle 30, and the flexible sleeve connector 50 is a light-transmitting flexible sleeve connector 50.

[0047] This application does not limit the materials of the light-transmitting air guide slot 20, the light-transmitting air collection baffle 30, and the light-transmitting flexible sleeve connector 50.

[0048] In one embodiment, a photovoltaic module support system based on a flexible duct 40 for wind energy self-cleaning includes an air guide duct 20 (high light transmittance), an air collection baffle 30 (high light transmittance), a flexible sleeve connector 50 (high light transmittance), and a flexible duct 40 with small pores.

[0049] Flexible ducts 40 with small pores are arranged longitudinally along the photovoltaic support 10, located between the photovoltaic modules. The air guide duct 20 and the air collection baffle 30 are made of integrated materials with high light transmittance and impact resistance. The air guide duct 20 is connected to the inclined beam of the support by a hinge.

[0050] The flexible sleeve connector 50 and the air guide duct 20 are connected and fixed by bolts on both sides of the flexible sleeve connector 50; the flexible pipe 40 with small air holes is connected to the air guide duct 20 by the flexible sleeve connector 50. When the flexible pipe 40 with small air holes is arranged between the components, the gap between the lower side of the flexible pipe 40 and the middle of the component is fixed with structural adhesive. On the one hand, this prevents the flexible pipe 40 from shaking, and on the other hand, it is conducive to waterproofing and prevents rainwater from falling onto the house through the gap.

[0051] The main components of the flexible duct self-cleaning photovoltaic module support system are all made of highly transparent materials, which will not cause shading to the modules.

[0052] The working principle is as follows:

[0053] 1. Wind energy utilization mechanism: Natural wind is accelerated into the duct through the air guide duct 20 and the air collection baffle 30, forming a high-pressure airflow. The airflow is directionally ejected from the small holes, forming an oblique wind curtain at a 15°-45° angle to the surface of the components, which removes dust and fallen leaves.

[0054] 2. Adaptive adjustment component: The flexible pipe 40 with small air holes is connected to the air guide 20 through the flexible sleeve connector 50. The flexible sleeve connector 50 and the air guide 20 are connected and fixed by bolts on both sides of the flexible sleeve connector 50. The air guide 20 and the wind baffle 30 are integrated materials with high light transmittance and impact resistance, which can optimize the wind capture efficiency.

[0055] 3. Flexible duct 40 with row of small holes: Optimize the matching of the tilt angle and spacing of the small holes to ensure maximum coverage of the air curtain and reduce the wind speed attenuation rate; the hole row adopts a single-sided arrangement to avoid mutual interference of airflow on both sides.

[0056] 4. Innovative air guide structure: The air guide channel with an arc cross section 20 is adopted to increase the wind speed.

[0057] The aforementioned photovoltaic module support system based on flexible duct 40 wind energy self-cleaning can utilize natural wind energy to form a directional wind curtain through the wind guide trough 20 and inclined row of small holes on the flexible duct 40, automatically removing dust and fallen leaves from the surface of the photovoltaic modules and solving the problem of power generation loss caused by dust accumulation.

[0058] Real-time cleaning reduces dust obstruction, improves component efficiency, and enhances power generation gain. It relies entirely on natural wind, consumes no additional energy, and achieves zero-energy operation. Its simple structure reduces manual maintenance costs throughout its lifespan, enabling low-cost maintenance. The flexible duct can adapt to different inclination angles and terrains, making it suitable for dust-prone environments such as deserts and farmland, demonstrating its environmental adaptability.

[0059] In summary, the photovoltaic module support system based on flexible duct wind energy self-cleaning provided by this utility model embodiment, by installing wind guide ducts on the photovoltaic support, changes the direction of the wind received on the wind-receiving surface through the duct structure, and guides the wind to the flexible duct through the wind-collecting baffle, and outputs it from the vent, realizing a blowing operation on the surface of the photovoltaic modules installed on the photovoltaic support. It can achieve directional cleaning of the modules, automatically remove dust and fallen leaves from the surface of the photovoltaic modules, and solve the problem of power generation loss caused by dust accumulation. Through real-time cleaning, dust obstruction is reduced, improving module efficiency; it relies entirely on natural wind, with no additional energy consumption; the structure is simple, reducing manual maintenance costs throughout its life cycle; the flexible duct can adapt to different inclination angles and terrains, making it suitable for scenarios prone to dust accumulation such as deserts and farmland.
