Photovoltaic power stations can be divided into two types: centralized and distributed. Centralized photovoltaic power stations are usually built in deserts, hills, mountains and other areas, while distributed photovoltaic power stations are built on roofs, parking lots and other buildings.

[0036] The wind energy cleaning device proposed in this application uses natural wind energy as a power source to drive the rotation of the cleaning member, so that the cleaning member can clean the dust, fallen leaves, etc. on the surface of the photovoltaic panel to reduce labor costs and energy costs. In addition, this application is provided with an energy storage member, which can temporarily store wind energy. When the accumulated wind energy reaches a certain value, it is released to drive the cleaning member to rotate, and then the energy storage member returns to the energy storage state from the release state, thereby achieving the effect of intermittent cleaning of the photovoltaic panel.

[0037] like Figure 1-3 As shown, the present disclosure proposes a wind energy cleaning device, including: a wind energy collection component 10, a directional rotation component 20, an energy storage component 30, a cleaning component 40 and a stopper 50;

[0038] The wind energy collection component 10 includes a rotating shaft 11, and the wind energy collection component can collect wind energy and convert it into external force to be transmitted through the rotation of the rotating shaft 11;

[0039] The directional rotation assembly 20 is connected to the rotating shaft 11 so that the rotating shaft 11 can rotate in a predetermined direction;

[0040] The energy storage component 30 includes an energy storage input end and an energy storage output end, the rotating shaft 11 is transmission-connected with the energy storage input end, and the energy storage input end can drive the energy storage output end to rotate coaxially with the rotating shaft 11;

[0041] The cleaning member 40 is connected to the energy storage output end and can rotate along with the energy storage output end;

[0042] A stopper 50, the energy storage output end abuts against the stopper 50, and the stopper 50 can provide a damping force, thereby blocking the rotation of the energy storage output end;

[0043] Among them, the external force is transmitted to the energy storage output end via the energy storage input end through the rotation of the rotating shaft 11. When the external force at the energy storage output end is less than the damping force of the stopper 50, the energy storage output end contacts the stopper 50, and the energy storage member 30 is in the energy storage state; when the external force at the energy storage output end is greater than the damping force of the stopper 50, the energy storage output end is disengaged from the stopper 50, and the external force is released by rotation, thereby driving the cleaning member 40 to rotate.

[0044] Specifically, the wind energy collection component 10 is used to convert wind energy into mechanical energy. The wind energy collection component 10 is in the form of a combination of a wind blade, a blade 12 or an impeller and a rotating shaft 11, which can capture natural wind energy and convert it into the rotational motion of the rotating shaft 11.

[0045] The directional rotation assembly 20 can make the shaft 11 rotate in a predetermined direction to prevent the reverse rotation from wasting energy. The directional rotation assembly 20 can adopt a one-way clutch or a ratchet 21 mechanism. The one-way clutch allows the shaft 11 to rotate freely in one direction and locks it in the other direction; the ratchet 21 mechanism realizes one-way rotation through the cooperation of the pawl 22 and the ratchet 21.

[0046] The energy storage input end of the energy storage element 30 is connected to the rotating shaft 11 to receive the mechanical energy transmitted by the rotating shaft 11 , and the energy storage output end is connected to the cleaning element 40 to store and release energy.

[0047] The energy storage element 30 can be in various forms, such as a spring, a flywheel, a hydraulic system, etc. The spring energy storage element 30 stores energy by compressing or stretching a spring; the flywheel energy storage element 30 stores energy by increasing the rotational kinetic energy of the flywheel; and the hydraulic system stores energy by compressing a liquid.

[0048] The cleaning member 40 cleans the surface of the photovoltaic panel and may be a brush, a scraper, etc., which can effectively remove dust and fallen leaves. The cleaning member 40 is kept horizontal with the surface of the photovoltaic panel so that the cleaning member 40 can cover the surface of the photovoltaic panel when rotating, thereby performing comprehensive contact cleaning.

[0049] The stopper 50 is used to provide damping force to control the rotation of the energy storage output end. The stopper 50 can be a brake with a friction plate, or a spring damper. Alternatively, it can be a baffle 31 equipped with a torsion spring, or a baffle 31 with elasticity. The elastic baffle 31 can be made of silicone material so that it can quickly recover after deformation and continue to stop the energy storage output end.

[0050] When the external force at the energy storage output end is less than the damping force of the stopper 50, the energy storage output end stops rotating and the energy storage member 30 is in an energy storage state; when the external force at the energy storage output end is greater than the damping force of the stopper 50, the energy storage output end overcomes the damping force, starts rotating and releases energy.

[0051] The working process is that the wind energy collection component captures natural wind energy and converts the wind energy into rotational motion through the rotating shaft 11. The directional rotation assembly 20 ensures that the rotating shaft 11 always rotates in a predetermined direction. The rotating shaft 11 transfers mechanical energy to the energy storage component 30 through the energy storage input end, and the energy storage component 30 begins to store energy. When the external force at the energy storage output end is greater than the damping force of the stopper 50, the energy storage output end overcomes the damping force, starts to rotate and releases the stored energy. The rotation of the energy storage output end drives the cleaning component 40 to rotate. The cleaning component 40 can clean dust and fallen leaves on the photovoltaic surface by rotating, thereby cleaning the surface of the photovoltaic panel.

[0052] After cleaning is completed, the energy storage output end contacts the stopper 50 again, and the energy storage element 30 enters the energy storage state again, preparing for the next cleaning.

[0053] The wind energy cleaning device proposed in the present disclosure utilizes natural wind energy, does not require additional electricity consumption, realizes automatic cleaning, and reduces labor costs. The energy storage mechanism of the energy storage member 30 can realize intermittent rotation cleaning of the cleaning member 40, has a high cleaning rate and does not require manual supervision. After rotating one circle, it releases energy and returns to the initial position, and does not cause obstruction to the surface of the photovoltaic panel.

[0054] In some embodiments, the wind energy cleaning device further includes a reduction transmission assembly 60, which includes a transmission input end and a transmission output end; the transmission input end is fixedly connected to the rotating shaft 11, and the transmission output end is fixedly connected to the energy storage output end.

[0055] Specifically, the reduction transmission device can increase the torque by reducing speed, so that the cleaning member 40 can more effectively remove dust and debris on the surface of the photovoltaic panel.

[0056] The transmission input end is fixedly connected to the rotating shaft 11 of the wind energy collection component 10, and receives the high-speed rotational motion from the wind energy collection component. The transmission output end is fixedly connected to the energy storage output end, and transmits the slowed low-speed high-torque motion to the energy storage component 30. The reduction transmission component 60 can be a gear reducer, a planetary gear reducer, a worm gear reducer, etc.

[0057] Among them, the wind energy collection component captures natural wind energy and converts the wind energy into high-speed rotational motion through the rotating shaft 11. The high-speed rotational motion of the rotating shaft 11 is transmitted to the reduction transmission component 60 through the transmission input end, and the reduction transmission component 60 converts the high-speed and low-torque motion into the low-speed and high-torque motion.

[0058] The reduction transmission assembly 60 can ensure that the cleaning element 40 works in an appropriate low-speed and high-torque state, thereby improving the cleaning effect. The reduction transmission assembly 60 can smoothly transmit motion, reduce impact and vibration, and improve the reliability and stability of the entire system. Different types of reduction transmission assemblies 60 can be selected according to actual needs, and the reduction ratio can be flexibly adjusted to adapt to different application scenarios.

[0059] In some embodiments, the reduction transmission assembly 60 is a planetary gear, and the planetary gear includes a sun gear 61, a planetary gear 62, a planet carrier 63, and an inner ring gear 64;

[0060] The sun gear 61 serves as a transmission input end, and the rotating shaft 11 is coaxially connected to the sun gear 61; there are multiple planetary gears 62, which are evenly spaced around the circumference of the sun gear 61, and the inner ring gear 64 is fixedly arranged on the outer circumference of the planetary gear 62. One side of the planetary gear 62 is in meshing contact with the sun gear 61, and the other side is in meshing contact with the inner ring gear 64; the planetary carrier 63 serves as a transmission output end and is fixedly arranged at the end of the planetary gear 62, and the planetary carrier 63 can rotate relative to the inner ring gear 64 following the rotation of the planetary gear 62; the planetary carrier 63 is fixedly arranged at the input end of the energy storage component 30.

[0061] Specifically, the rotating shaft 11 is coaxially fixedly connected with the sun gear 61, and transmits the high-speed rotational motion to the sun gear 61. The high-speed rotational motion of the sun gear 61 is transmitted to the planetary gear 62 meshed therewith. The planetary gear 62 is meshed with the sun gear 61 and the inner gear ring 64 at the same time, so under the drive of the sun gear 61, the planetary gear 62 not only rotates around its own axis, but also revolves along the inner surface of the inner gear ring 64. This composite motion of the planetary gear 62 is transmitted through the planetary carrier 63, and the planetary carrier 63, as the transmission output end, rotates following the revolution of the planetary gear 62. The planetary carrier 63 is fixedly connected to the input end of the energy storage component 30, and transmits the low-speed and high-torque motion to the energy storage component 30.

[0062] The energy storage member 30 starts to store energy until the external force at the energy storage output end is greater than the damping force of the stopper 50. When the external force at the energy storage output end is greater than the damping force of the stopper 50, the energy storage output end overcomes the damping force, starts to rotate and releases the stored energy.

[0063] Among them, the planetary gear system can achieve a larger reduction ratio while occupying a smaller space, reducing the volume of the overall device. The multiple planetary gears 62 in the planetary gear system share the load at the same time, reducing the load of a single gear and improving the transmission efficiency.

[0064] The sun gear 61 is made of high-strength alloy steel with good wear resistance and fatigue resistance. It is designed according to the required reduction ratio and speed requirements, and is usually smaller in diameter to adapt to high-speed rotation.

[0065] The number of planetary gears 62 is usually 3-6, and the specific number depends on the reduction ratio and load requirements. High-strength alloy steel or stainless steel can be used, which has good wear resistance and fatigue resistance. Through precise processing and installation, the planetary gears 62 are evenly distributed on the circumference of the sun gear 61.

[0066] The planet carrier 63 can be made of high-strength alloy steel or cast iron, has good rigidity and strength, can support multiple planetary gears 62, and can rotate with the revolution of the planetary gears 62. The inner gear ring 64 is fixed to the outer shell of the device by bolts or welding to ensure that it remains stationary during operation. Through the above design, the planetary gear reduction transmission assembly 60 in the wind energy cleaning device can effectively reduce the high-speed rotational motion transmitted by the wind energy collection assembly 10 to a low-speed high-torque motion suitable for the cleaning member 40, thereby improving the cleaning effect and the overall performance of the system.

[0067] In some embodiments, the energy storage member 30 is a coil spring, the end of the inner circle of the coil spring is the energy storage input end, and the end of the outer circle of the coil spring is the energy storage output end.

[0068] Specifically, a coil spring is a spiral elastic element, usually made of spring steel or other highly elastic materials.

[0069] When the rotating shaft 11 is directly connected to the coil spring, the rotating shaft 11 is fixedly connected by keyways, pins or threads to ensure the reliability of torque transmission. The inner ring end of the coil spring can be designed as a flat end or a hook end for easy installation and fixing.

[0070] When the planetary gear is connected to the energy storage member 30, it is fixedly connected to the planetary carrier 63 by keyways, pins or threads to ensure the reliability of torque transmission. The inner ring end of the coil spring can be designed as a flat end or a hook end for easy installation and fixing.

[0071] The outer ring end of the coil spring is fixedly connected to the cleaning member 40 by means of a keyway, a pin or a thread, etc., to ensure the reliability of torque transmission. The outer ring end can be designed as a flat end or a hook end for easy installation and fixing.

[0072] In some embodiments, the wind energy collection component includes a blade 12 , wherein the blade 12 is multiple and evenly spaced around the rotating shaft 11 , one end of the blade 12 is fixedly connected to the rotating shaft 11 , and the other end extends away from the rotating shaft 11 .

[0073] Specifically, a plurality of blades 12 are evenly spaced and arranged around the rotating shaft 11 , one end of each blade 12 is fixedly connected to the rotating shaft 11 , and the other end of each blade 12 extends in a direction away from the rotating shaft 11 .

[0074] The rotating shaft 11 is fixedly connected to the blades 12, and the wind energy captured by the blades 12 is converted into rotational motion. The fixed connection between the rotating shaft 11 and the blades 12 can be achieved by welding, bolt connection or a dedicated fixing device to ensure the reliability and strength of the connection.

[0075] When natural wind flows through the blades 12, the blades 12 are acted upon by the wind force, generating a rotational torque. The design of the blades 12 enables them to efficiently capture wind energy under the action of wind force and convert the wind energy into mechanical energy. The rotational torque of the blades 12 is transmitted to the rotating shaft 11 through a fixed connection with the rotating shaft 11, causing the rotating shaft 11 to rotate. The rotational motion of the rotating shaft 11 is further transmitted to the subsequent reduction transmission assembly 60 and the energy storage member 30, and finally drives the cleaning member 40 to work.

[0076] The number of blades 12 is set to 3-6, and the specific number depends on the wind energy collection efficiency and the structural stability.

[0077] The blade 12 is made of high-strength lightweight materials, such as glass fiber reinforced plastic (GFRP), carbon fiber composite materials or aluminum alloy, and has good strength, rigidity and weather resistance. The shapes of the blade 12 include straight blades 12: simple straight plate-shaped blades 12, suitable for low wind speed environments. Curved blades 12: The curved surface design can improve the efficiency of wind energy capture and reduce airflow resistance. Airfoil blades 12: Similar to the shape of an airplane wing, it has a higher lift coefficient and a lower drag coefficient and is suitable for high wind speed environments.

[0078] The arrangement of multiple blades 12 can effectively capture natural wind energy and improve wind energy conversion efficiency. The design of evenly spaced blades 12 ensures the stability and balance of the structure and reduces vibration and noise. In addition, by adjusting the number, shape and installation angle of the blades 12, it can adapt to different wind speed and wind direction conditions and improve the application range of the system. The blades 12 and the rotating shaft 11 have a simple structure, are easy to install and maintain, and reduce maintenance costs.

[0079] In some embodiments, it also includes a support member 90 and a carrying platform 70 , wherein the carrying platform 70 is fixedly disposed on the support member 90 , the energy storage member 30 is disposed at the upper end of the carrying platform 70 , and the cleaning member 40 is disposed at the lower end of the carrying platform 70 .

[0080] Specifically, the support member 90 provides support for the structure of the entire wind energy cleaning device to ensure that the device operates stably under various environmental conditions. The support member 90 can also adjust the inclination angle relative to the bearing surface (such as the ground, the roof, etc.) to adapt to the inclined arrangement of the photovoltaic panel so that the cleaning member 40 is in parallel contact with the surface of the photovoltaic panel.

[0081] The support member 90 may include a column, a base, and reinforcing ribs. Among them, the column is the main load-bearing part, usually cylindrical or square in cross section, and the height is determined according to the installation position and the height of the wind energy collection component. The base is fixed to the ground or the mounting platform to provide a stable foundation. The base can be a flat plate or a frame type, and the appropriate form can be selected according to the installation environment. Reinforcing ribs are set between the column and the base to increase the rigidity and stability of the structure. Mounting holes are set on the base and the column for fixing the support member 90 and connecting other components.

[0082] The carrying platform 70 is fixedly arranged on the support member 90, and the fixing arrangement can be realized by interference fit through the column of the support member 90 or by welding. It is used to carry the energy storage member 30, and can be set as a flat plate or a frame, wherein the carrying platform 70 does not interfere with the rotation of the energy storage output end of the energy storage member 30, especially when the energy storage member 30 is a coil spring, the outer ring end of the coil spring extends out of the carrying platform 70, and then is connected to the cleaning member 40 at the lower end of the carrying platform 70.

[0083] In some embodiments, the wind energy cleaning device further includes a protective cover 80 , which is fixed to the rotating shaft 11 through a bearing, and is sleeved on the outside of the energy storage component 30 and the reduction transmission component, and is placed on the upper end of the cleaning component 40 .

[0084] Specifically, the protective cover 80 is used to protect the internal components: prevent external factors such as dust, rain, direct sunlight, etc. from damaging the energy storage component 30 and the reduction transmission component, and also prevent operators from accidentally contacting high-speed rotating components, thereby improving safety.

[0085] The protective cover 80 has a certain weight and can be made of stainless steel, which has good corrosion resistance, weather resistance and mechanical strength to ensure long-term stable operation.

[0086] A sliding bearing may be provided between the rotating shaft 11 and the protective cover 80 so that the protective cover 80 can slide relative to the rotating shaft 11 without rotating with it.

[0087] The sliding bearing is usually composed of two parts, the inner ring is fixed on the rotating shaft 11, and the outer ring is fixed on the protective cover 80. A mounting hole is set on the outer ring of the sliding bearing for fixing the protective cover 80.

[0088] The inner ring of the sliding bearing is fixed on the rotating shaft 11 to ensure that the inner ring fits tightly with the rotating shaft 11, and the outer ring of the sliding bearing is fixed on the protective cover 80 to ensure that the outer ring fits tightly with the protective cover 80. When installing the protective cover 80, the protective cover 80 is fixed on the rotating shaft 11 through the outer ring of the sliding bearing to ensure that the protective cover 80 can slide relative to the rotating shaft 11. The protective cover 80 is fixed to the outer ring of the sliding bearing using bolts or other fixing methods.
