Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic parking sheds, and specifically relates to an intelligent photovoltaic parking shed. Background Art

[0002] An intelligent photovoltaic parking shed is an innovative facility that combines photovoltaic power generation technology with a parking shed and incorporates intelligent management. It not only provides the traditional parking function but also makes full use of solar energy resources to achieve sustainable energy utilization.

[0003] In a Chinese patent with the patent publication number CN221856349U, a photovoltaic parking shed is disclosed, which includes a photovoltaic panel assembly and a plurality of support frames for supporting the photovoltaic panel assembly. The photovoltaic panel assembly includes a photovoltaic panel frame and photovoltaic panels installed on the photovoltaic panel frame. A plurality of ball head rotating grooves are fixedly installed below the photovoltaic panel frame, and a ball head is installed in each ball head rotating groove. Each support frame corresponds to one ball head. Each support frame includes a telescopic rod and a ball head connection device installed at the top of the telescopic rod for cooperating with the ball head to hold it tightly. The ball head connection device includes a support platform fixedly installed at the top of the telescopic rod, a clamping member installed on the support platform, and a locking member for clamping the ball head on the clamping member. In the above photovoltaic parking shed, the photovoltaic panel assembly and the support frame are connected by a ball head, and the angle of the photovoltaic panel assembly can be adjusted to follow the sun's angle in all directions, ensuring the maximum power output of the photovoltaic module.

[0004] However, the device in the cited document still has the following defects during specific use: 1. Compared with the device in the cited document, the angle of the photovoltaic panel assembly can be adjusted to follow the sun's angle in all directions to ensure the maximum power output of the photovoltaic module. However, in actual use, since the sun is very far away from the earth, although the photovoltaic panel assembly can adjust its angle to follow the sun, due to the huge height difference, even with angle adjustment, compared with the traditional flat-mounted photovoltaic modules, it can only improve the light reception situation to a certain extent. Moreover, the scattering, absorption, etc. of sunlight by the earth's atmosphere, as well as the change in the solar radiation intensity itself at different time periods, will make it difficult to maximize the utilization of electric energy solely by angle adjustment.

[0005] Secondly, when the position of the photovoltaic panel assembly changes, its originally shielded internal structures (such as connection lines, control devices, etc.) will be exposed, which will make these internal structures more vulnerable to external environmental factors, such as rain erosion, dust accumulation, mechanical collision, etc., thereby reducing the service life and stability of the equipment. Moreover, in bad weather conditions such as rain and snow, if the photovoltaic panel assembly cannot return to a proper protection position, it will be directly impacted by rain and snow, causing problems such as damage to the surface of the photovoltaic panel and electrical short circuits, seriously affecting the normal operation and safety of the equipment.

[0006] At the same time, according to the running cycle of the sun, the direction is inconsistent every time the sun appears and sets. Therefore, the photovoltaic panel assembly needs to be repositioned and adjusted. Such steps not only increase the operating burden and energy consumption of the equipment, but also cause time delay during the adjustment process, making the photovoltaic panel assembly unable to receive sunlight in a timely and effective manner, thus affecting the power generation efficiency.

[0007] 2. Compared with the prior art, since the photovoltaic module is installed on the top of the parking shed and is designed to be inclined front and back, when strong wind weather occurs, if the strong wind blows from the front and back directions of the parking shed, the inclined surface of the photovoltaic module is like a deflector, and the strong wind can flow along the inclined surface. The streamline of the air flow is relatively regular, and the direction and speed of the air flow change relatively gently during the flow process. Therefore, it is not easy to form large-area eddies and turbulences. Thus, the flow resistance of the strong wind is small. When the strong wind blows from the left and right directions, the parking shed and the photovoltaic module as a whole form a relatively large vertical blocking surface. When the wind encounters this blocking surface, its flow is blocked. On one side of the blocking surface, the wind speed will decrease sharply and the pressure will increase, while on the other side, the wind will bypass the object to form a region of fast flow, and the pressure will decrease. This pressure difference will cause the movement of the air flow to become chaotic, forming obvious eddies and turbulences, and thus generating a large resistance.

[0008] The large resistance will cause the parking shed and the photovoltaic module to bear greater wind loads. For the supporting structure of the parking shed, such as columns, crossbeams, etc., they will deform or even break due to being unable to bear excessive stress. For the photovoltaic module, its frame, connecting components, etc. will also be damaged due to excessive stress, resulting in the loosening, displacement, or even breakage of the photovoltaic panels. Moreover, due to the resistance effect generated by the strong wind, the photovoltaic module will have a certain angular offset. The power generation efficiency of the photovoltaic module is closely related to the incident angle of sunlight. Once the angle changes, it will cause the sunlight not to irradiate the photovoltaic panel at the optimal angle, thereby reducing the power generation efficiency.

[0009] Therefore, in view of this, the present invention proposes an intelligent photovoltaic parking shed to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0010] To solve the above technical problems, the present invention provides an intelligent photovoltaic parking shed to solve the technical problems raised in the above background art.

[0011] To achieve the above object, the technical solution adopted by the present invention is as follows: an intelligent photovoltaic parking shed, including a shed skeleton, a photovoltaic module is installed on the top of the shed skeleton, a control module is installed below the photovoltaic module, and a wind force regulation mechanism is arranged above the shed skeleton. The wind force regulation mechanism is used to ensure the overall use stability of the shed skeleton and locally dissipate heat from the control module.

[0012] Furthermore, the wind control mechanism includes stabilizing bins symmetrically installed on the side walls of the shed framework. The outer walls of the stabilizing bins are uniformly fixedly connected with flow dividing plates. Wind shielding plates are installed inside the stabilizing bins. Threaded collar rings are uniformly fixedly connected to the side walls of the wind shielding plates. Threaded shafts are threadedly connected inside the threaded collar rings. Pulley wheels are fixedly connected to the lower surfaces of the threaded shafts. A transmission belt is installed outside the pulley wheels. Ventilation pipes are uniformly installed on the surface of the photovoltaic module. Filter elements are installed inside the ventilation pipes. Diffuser covers are installed on the outer walls of the filter elements. Through slots are uniformly formed on the surfaces of the ventilation pipes. Partition plates are fixedly connected inside the ventilation pipes.

[0013] Furthermore, the flow dividing plates are integrally in an isosceles triangle shape, and the sides of the flow dividing plates away from the stabilizing bins are in a pointed shape. Ventilation holes are formed through between every two of the flow dividing plates.

[0014] By adopting the above technical solution, when strong wind currents blow towards the shed framework, the isosceles triangle-shaped flow dividing plates can divide and guide the air currents.

[0015] Furthermore, a ball screw structure is formed between the threaded collar rings and the threaded shafts. The threaded collar rings are initially located at the bottommost parts outside the threaded shafts. The stabilizing bins and the wind shielding plates are slidably connected through the threaded collar rings.

[0016] By adopting the above technical solution, according to the increase of the wind force, through the rotation of the threaded shafts, the wind shielding plates are driven to move, increasing the contact area with the wind force.

[0017] Furthermore, a driving motor is installed below the threaded shaft at the center position. Every two adjacent pulley wheels are in transmission connection through the transmission belt.

[0018] Furthermore, the ventilation pipes are integrally in a curved arc shape. The filter elements are located at the port positions of the ventilation pipes. The filter elements are integrally composed of multiple fan-shaped plates installed in an inclined manner, and the diffuser covers are integrally in a shape that is narrower on the left and wider on the right.

[0019] Furthermore, the partition plates are located at the center positions of the ventilation pipes, dividing the interiors of the ventilation pipes into upper and lower layers. The through slots are located in the upper half layer of the ventilation pipes.

[0020] By adopting the above technical solution, when the wind force flows through the lower half layer of the ventilation pipes as a fluid, it fully contacts the circuit housing, effectively reducing the working temperature of the circuit. The upper half layer of the ventilation pipes guides the wind force to locally clean the surface of the photovoltaic panel, relatively keeping the surface of the photovoltaic panel clean.

[0021] Furthermore, a light energy enhancement mechanism is evenly installed above the photovoltaic module. The light energy enhancement mechanism is used to improve the power conversion efficiency of the photovoltaic module and regularly clean its surface. The light energy enhancement mechanism includes support seats symmetrically installed above the shed frame. Reflectors are installed above the support seats. Adjusting rollers are installed on one side of the support seats close to each other. Round balls are evenly installed on the surface of the adjusting rollers. A connecting curved rod is fixedly connected to the side wall of the adjusting roller.

[0022] Furthermore, chutes are respectively opened at the positions of the side walls of the support seats corresponding to the adjusting rollers. The support seats and the adjusting rollers are slidably connected through the chutes. A continuous threaded groove is opened on the surface of the adjusting roller. The round balls are rotatably connected to the concave bottom positions of the external threaded grooves of the adjusting roller.

[0023] By adopting the above technical solution, the round balls will generate tiny impact forces on the surface of the photovoltaic panel. Stubborn stains usually have a relatively tight adhesion structure.

[0024] Furthermore, the photovoltaic module includes battery components and photovoltaic panels. The ventilation pipe is located between adjacent photovoltaic panels in the photovoltaic module. The upper half layer of the ventilation pipe corresponds to the surface of the photovoltaic panels in the photovoltaic module. The lower half layer of the ventilation pipe corresponds to the surface of the battery components in the photovoltaic module. The control module includes a line cable, an inverter, a charging component, and a wind sensor. The battery components in the photovoltaic module and the line cable in the control module are on the same layer. The wind sensor in the control module is electrically connected to the drive motor.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) Firstly, by arranging stable bins with a continuous curvature circular arc outer profile on the left and right sides of the shed frame, the present device guides the lateral flowing wind to form an attached wall effect, reduces the pressure difference resistance caused by airflow separation, and is paired with a splitter plate in an isosceles triangle shape with the tip facing outwards and ventilation holes between the splitter plates, which can effectively guide the strong wind airflow to disperse to both sides and flow through the ventilation holes. According to the principle of aerodynamics, the wind resistance coefficient is greatly reduced, thereby improving the airflow characteristics around the shed frame, effectively suppressing the generation of airflow separation and vortices, and making the airflow bypass the shed frame more smoothly.

[0026] Relative to the prior art, through the diversion design of the stable bin paired with the splitter plate and the adjustable wind baffle structure, the present device realizes the effective control and utilization of strong wind, guides the airflow streamline to be more regular, reduces the formation of large-area vortices and turbulence, thereby significantly reducing the wind flow resistance on both sides of the shed frame and improving the structural stability of the shed frame during use.

[0027] Secondly, when the wind force increases, the wind sensor senses and triggers the drive motor to drive the arc-shaped windshields to move upward, increasing the windshield area on both sides of the shed skeleton. This method of adjusting the windshield area according to the wind force can maintain the angle stability of the photovoltaic module, ensure that sunlight shines on the photovoltaic panel at the best angle, avoid the reduction of power generation efficiency caused by the angle deviation of the photovoltaic panel due to strong wind, and thus improve the power generation stability and energy conversion efficiency of the photovoltaic module.

[0028] Compared with the prior art, when the wind force is weak, the arc-shaped windshields are in a lower position, which does not affect normal ventilation and lighting. When the wind force is strong, the arc-shaped windshields move upward, increasing the windshield area on both sides of the shed skeleton, further reducing the impact of strong wind on the shed skeleton and photovoltaic module, and improving the overall wind resistance of the shed skeleton.

[0029] Among them, when strong wind blows from both left and right sides, the brackets on the wind-facing side move downward slightly to form an inclined plane, which can further guide the airflow to flow along the inclined plane. Moreover, the dynamic inclined plane formed by the telescopic brackets is equivalent to adding an additional wind resistance mechanism to the shed. In the case of strong wind, this dynamic adjustment can cooperate with structures such as the stable bin and the diversion plate to form a more comprehensive and flexible wind resistance system, enhancing the wind resistance redundancy of the shed under different wind force conditions and making the shed more reliable when facing extreme strong wind.

[0030] Compared with the shed skeleton with a fixed structure in the prior art, the dynamic change of the telescopic brackets enables the shed to make real-time adjustments according to the actual wind force situation, with stronger dynamic adaptability. In the prior art, when the shed faces strong wind in different directions and intensities, the structure is relatively fixed and it is difficult to make targeted adjustments. However, this telescopic structure can automatically form an inclined plane according to the wind direction and wind force, better coping with the complex and changeable wind environment.

[0031] (2) When strong wind appears in the inclined direction of the shed skeleton, this device can use the ventilation pipe to guide the wind to flow on the surface of the photovoltaic module. Moreover, the lower half layer of the ventilation pipe corresponds to the layout of the battery components and the circuit cables. Therefore, when the wind flows through the lower half layer of the ventilation pipe, it will exchange heat with the circuit housing. According to Newton's law of cooling, the heat transfer rate between the fluid and the solid surface is proportional to the temperature difference between them. By continuously removing heat through the flow of the wind, the working temperature of the circuit is effectively reduced. Through this efficient heat exchange mechanism, it helps to maintain the stable operation of the circuit, reduce problems such as the performance degradation and shortened lifespan of electronic components caused by overheating during continuous operation, and thus improve the reliability of the internal circuit of the photovoltaic module, ensure the stable operation of the entire photovoltaic module system, and reduce the downtime maintenance time and cost caused by circuit failures.

[0032] Secondly, the upper layer of the ventilation pipe is designed to be higher than the surface of the photovoltaic module to guide the wind to clean the surface of the photovoltaic panel. From the perspective of fluid dynamics, shear force will be generated when the wind flows over the surface of the photovoltaic panel. This shear force can overcome the adhesion of impurities, fallen leaves, etc. to the surface of the photovoltaic panel and blow them away. Through wind cleaning, the surface of the photovoltaic module is kept clean, ensuring that sunlight can fully irradiate the photovoltaic panel, thereby improving the power generation efficiency. Moreover, in the face of bad weather, the accumulated rain and snow will not only increase the weight of the photovoltaic module and cause additional pressure on the support structure, but also further block the sunlight, seriously affecting the power generation efficiency. However, the flow of wind can timely blow away the accumulated rain and snow, reduce the burden on the photovoltaic module, and at the same time restore its effective absorption of sunlight, thus ensuring the stable operation of the device under different meteorological conditions.

[0033] Compared with the prior art, the device comprehensively utilizes the wind by guiding the wind through the hierarchical design of the ventilation pipe. On the one hand, the wind is used to take away the heat of the circuit, improving the reliability and stability of the circuit. On the other hand, by guiding the wind to clean the surface of the photovoltaic panel, the cleanliness of the photovoltaic module is maintained, the power generation efficiency is improved, and at the same time, the adaptability of the device to bad weather is enhanced.

[0034] Among them, a filter element is introduced at the port of the ventilation pipe. The filter element is composed of multiple sector plates installed in an inclined manner, which can form an effective barrier at the port of the ventilation pipe to block larger impurities outside, ensuring the smoothness of the air flow channel in the ventilation pipe and guaranteeing the normal operation of the whole system.

[0035] Secondly, when the stable air flow guided by the filter element passes through the ventilation pipe, it can generate a certain scouring effect to blow out the fine impurities inside the ventilation pipe. This self-cleaning function can keep the inside of the ventilation pipe clean, reduce the air flow resistance, and extend the service life of the ventilation pipe. The shape of the ventilation expansion hood with a narrower left side and a wider right side further optimizes the air flow, making the air flow smoother when passing through the ventilation pipe and enhancing the effect of blowing out fine impurities.

[0036] (3) The device introduces an adjusting roller at the top of the photovoltaic module and opens continuous threaded grooves on its outer wall. The continuous threaded grooves increase the contact area and friction force with the surface of the photovoltaic panel. The existence of the threaded grooves makes the contact surface rougher, increasing the friction coefficient. Under the same normal pressure, the friction force increases, which helps the adjusting roller to more effectively adsorb and remove impurities such as dust and stains on the surface of the photovoltaic panel. For example, for some stains with strong viscosity, the adjusting roller with threaded grooves can peel off the stains from the surface of the photovoltaic panel by virtue of the increased friction force.

[0037] Among them, the round ball bearings installed at the recessed positions of the threaded grooves play a role in rolling cleaning during the cleaning process. When the adjusting roller moves on the surface of the photovoltaic panel, the round ball bearings will roll in the threaded grooves. This rolling method can clean the surface of the photovoltaic panel more meticulously. The rolling of the round ball bearings can generate tiny impact forces, which helps to break the attachment structure of stubborn stains and make them easier to be cleaned off. At the same time, the rolling of the round ball bearings can also reduce the direct friction between the adjusting roller and the surface of the photovoltaic panel, reducing the risk of damage to the surface of the photovoltaic panel.

[0038] Compared with the prior art, it is necessary to repeat the operation multiple times to complete the cleaning of the entire photovoltaic panel. Moreover, some cleaning tools will cause scratches or damage to the surface of the photovoltaic panel. Through the combination of the threaded grooves on the surface of the adjusting roller and the round ball bearings, this device realizes more efficient and meticulous cleaning. While improving the cleaning efficiency and quality, it also protects the performance and lifespan of the photovoltaic panel.

[0039] Among them, introducing a reflector above the support base of this device can refract and collect the light scattered by the sun, changing the propagation path of the light that originally could not directly irradiate onto the photovoltaic panel and converging it onto the surface of the photovoltaic panel, thereby generating more electrons to increase the photocurrent and ultimately improving the power conversion efficiency of the photovoltaic module.

[0040] Moreover, the reflector can change the incident angle of the light, enabling the photovoltaic panel to receive more light at different solar altitude angles. During the day, the position of the sun changes continuously. Traditional photovoltaic modules can only receive direct light and some scattered light within a specific angle range, while the reflector, through the refraction effect, can guide scattered light at different angles onto the photovoltaic panel, which is equivalent to expanding the range of illumination angles that the photovoltaic module can utilize. In addition, during periods with a relatively low solar altitude angle such as in the morning and evening, the reflector can also collect and refract the light, extending the effective light-receiving time of the photovoltaic module and further improving the overall power generation efficiency.

[0056] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0057] It should be noted that the structures and working principles of the above-mentioned shed framework 1, photovoltaic module 11, and control module 12 and other devices belong to the prior art and will not be elaborated here.

[0058] Example 1: Please refer to Figure 1 and Figure 2As shown in the figure, an intelligent photovoltaic parking shed includes a shed skeleton 1. A photovoltaic module 11 is installed at the top of the shed skeleton 1, and a control module 12 is installed below the photovoltaic module 11. A wind control mechanism 2 is arranged above the shed skeleton 1. The wind control mechanism 2 is used to ensure the overall use stability of the shed skeleton 1 and locally dissipate heat from the control module 12.

[0059] It should be noted that the photovoltaic module 11 includes battery components and photovoltaic panels. The ventilation pipe 210 is located between adjacent photovoltaic panels in the photovoltaic module 11. The upper half layer of the ventilation pipe 210 corresponds to the surface of the photovoltaic panels in the photovoltaic module 11, and the lower half layer of the ventilation pipe 210 corresponds to the surface of the battery components in the photovoltaic module 11. The control module 12 includes a line cable, an inverter, a charging component, and a wind sensor. The battery components in the photovoltaic module 11 and the line cable in the control module 12 are on the same level, and the wind sensor in the control module 12 is electrically connected to the drive motor 29.

[0060] Please refer to Figures 2 to 7 As shown in the figure, the wind control mechanism 2 includes stabilizing bins 21 symmetrically installed on the side walls of the shed skeleton 1. The outer walls of the stabilizing bins 21 are uniformly fixedly connected with flow splitting plates 22. Wind baffle plates 24 are installed inside the stabilizing bins 21. Threaded collar rings 25 are uniformly fixedly connected to the side walls of the wind baffle plates 24. Threaded shafts 26 are threadedly connected inside the threaded collar rings 25. Pulley wheels 27 are fixedly connected to the lower surfaces of the threaded shafts 26. A transmission belt 28 is installed outside the pulley wheels 27.

[0061] It should be noted that the flow splitting plates 22 are in an isosceles triangle shape as a whole, and the side of the flow splitting plate 22 away from the stabilizing bin 21 is in a pointed shape. Ventilation holes 23 are penetrated and opened between every two flow splitting plates 22. A ball screw structure is formed between the threaded collar rings 25 and the threaded shafts 26. The threaded collar rings 25 are initially located at the bottommost part outside the threaded shafts 26. The stabilizing bins 21 and the wind baffle plates 24 are slidably connected through the threaded collar rings 25. A drive motor 29 is installed below the threaded shaft 26 at the center position. Every two adjacent pulley wheels 27 are in transmission connection through the transmission belt 28.

[0062] Specifically, the Coandă effect, also known as the wall attachment effect, refers to the tendency of a fluid (such as air) to leave its original flow direction and instead flow along the surface of a protruding object. When there is viscosity between the fluid and the surface of the object it flows over, the flow rate of the fluid will slow down. According to Bernoulli's principle, a fluid with a slower flow rate has a greater pressure, while a fluid with a faster flow rate has a smaller pressure. Under the action of this pressure difference, the fluid will adhere to the surface of the object and flow.

[0063] On both the left and right sides of the shed frame 1 in this device, there are stable bins 21 with continuously curved circular arc outer contours. When the lateral flowing wind passes through the stable bins 21, due to their circular arc outer contours, the wind will adhere to the surface of the stable bins 21 and flow, forming the wall attachment effect. The windward direction of the shed frame 1 is the high-pressure area, and the wall attachment effect enables the air flow to flow more closely along the surface of the shed frame 1, reducing the possibility of air flow separation, thereby reducing the pressure difference resistance caused by air flow separation.

[0064] The flow splitter 22 is designed as an isosceles triangle with its tip facing outward. When the strong wind air flow blows towards the shed frame 1, the isosceles triangle flow splitter 22 can divide and guide the air flow. From the perspective of aerodynamics, when the air flow encounters the tip of the flow splitter 22, it will naturally split to both sides, just like water flow splitting when encountering an obstacle. This splitting effect causes the strong wind air flow that was originally concentrated and blowing towards the shed frame 1 to disperse to both sides, avoiding the excessive accumulation of air flow on the force-bearing surface of the parking shed frame, thereby reducing the wind force borne by the shed frame 1.

[0065] Moreover, the ventilation holes 23 provided between the flow splitters 22 play a role in dredging the air flow. After the strong wind air flow is guided by the flow splitters 22 and dispersed to both sides, part of the air flow will flow through the ventilation holes 23. The existence of the ventilation holes 23 provides an additional flow channel for the air flow, further alleviating the pressure of the air flow around the shed frame 1. According to the continuity equation, in the flow of an incompressible fluid, the mass flow rate of the fluid is constant in the same flow tube. The existence of the ventilation holes 23 increases the flow area of the air flow, enabling the air flow to pass more smoothly and avoiding the blockage of the air flow and the formation of local high pressure.

[0066] At the same time, as the wind force gradually increases, the wind force sensor in the control module 12 will trigger the driving motor 29 to rotate forward. Since the structure between the threaded collar 25 and the threaded shaft 26 is similar to that of a ball screw, and the pitch of the threaded shaft 26 is equal to the inner diameter size of the threaded collar 25, and the tangential of the thread and the cylinder with the horizontal plane is greater than 45 degrees. Therefore, when the driving motor 29 drives the threaded shaft 26 to rotate through the pulley 27 and the transmission belt 28, the rotational force that maintains the rotation can be smoothly transmitted to the threaded collar 25, thereby driving it to move upward and synchronously driving the windshield 24 to move upward.

[0067] After the arc-shaped windshield 24 moves, the wind force can act dispersedly on a larger area. A larger windshield area can have a more significant impact on the surrounding air flow field. After the arc-shaped windshield 24 moves upward and increases in area, it will guide the air flow to bypass the shed frame 1 and the photovoltaic module 11 more gently. In fluid mechanics, the smooth flow of the air flow can reduce the impact force and unstable acting force of the air flow on the object. When the air flow can pass more smoothly, the lateral thrust and torsional force on the photovoltaic module 11 will decrease, thereby helping to maintain the angular stability of the photovoltaic module 11.

[0068] Please refer to Figures 8 to 10 As shown, ventilation pipes 210 are evenly installed on the surface of the photovoltaic module 11. Filter elements 211 are installed inside the ventilation pipes 210. An expansion cover 212 is installed on the outer wall of the filter element 211. Through grooves 213 are evenly formed on the surface of the ventilation pipes 210. Partition plates 214 are fixedly connected inside the ventilation pipes 210.

[0069] It should be noted that a driving motor 29 is installed below the threaded shaft 26 at the exact center position. Every two adjacent belt pulleys 27 are in transmission connection through a transmission belt 28. The ventilation pipes 210 as a whole are in a curved arc shape. The filter element 211 is located at the port position of the ventilation pipes 210. The filter element 211 as a whole is composed of multiple fan-shaped plates installed in an inclined manner. And the expansion cover 212 is in a shape that is narrow on the left and wide on the right. The partition plate 214 is located at the exact center position of the ventilation pipes 210, dividing the interior of the ventilation pipes 210 into upper and lower layers. The through grooves 213 are located in the upper half layer of the ventilation pipes 210.

[0070] Specifically, when strong wind appears in the tilting direction of the shed frame 1, the ventilation pipes 210 guide the wind to flow on the surface of the photovoltaic panel. The lower half layer of the ventilation pipes 210 corresponds to the layout of the battery components and the circuit cables. Since heat is generated during the operation of the circuit, the temperature of the circuit housing is higher than the temperature of the surrounding air, creating a temperature difference. When the wind, as a fluid, flows through the lower half layer of the ventilation pipes 210, it comes into full contact with the circuit housing. According to Newton's law of cooling, heat will transfer from the higher-temperature circuit housing to the lower-temperature air. Therefore, the flow of the wind continuously renews the air in contact with the circuit housing, ensuring a continuous temperature difference, thereby continuously taking away heat and effectively reducing the operating temperature of the circuit.

[0071] Regarding the upper half layer of the ventilation pipes 210, from the perspective of fluid dynamics, when a fluid (here the wind) flows on the surface of a solid (the surface of the photovoltaic panel), shear force will be generated. The shear force is caused by the viscosity of the fluid and the velocity gradient. In the fluid layer close to the surface of the photovoltaic panel, due to the viscous effect, its velocity will be blocked by the surface of the photovoltaic panel and be relatively low, while the velocity of the fluid layer far from the surface of the photovoltaic panel is relatively high. In this way, a velocity gradient is formed. According to Newton's law of internal friction, the shear force generated when the wind flows on the surface of the photovoltaic panel acts on objects such as impurities and fallen leaves, and then the wind can be guided through the upper half layer of the ventilation pipes 210 to locally clean the surface of the photovoltaic panel, relatively keeping the surface of the photovoltaic panel clean.

[0072] Example 2: On the basis of Example 1, please refer to Figures 8 to 12As shown in the figure, a light energy enhancement mechanism 3 is evenly installed above the photovoltaic module 11. The light energy enhancement mechanism 3 is used to improve the power conversion efficiency of the photovoltaic module 11 and regularly clean its surface. The light energy enhancement mechanism 3 includes bracket seats 31 symmetrically installed above the shed frame 1. Reflective mirrors 32 are installed above the bracket seats 31. Adjusting rollers 33 are installed on one side of the bracket seats 31 close to each other. Round balls 34 are evenly installed on the surface of the adjusting rollers 33. A connecting curved rod 35 is fixedly connected to the side wall of the adjusting roller 33.

[0073] It should be noted that chutes are provided at the positions of the side walls of the bracket seats 31 corresponding to the adjusting rollers 33. The bracket seats 31 and the adjusting rollers 33 are slidably connected through the chutes. Continuous threaded grooves are provided on the surface of the adjusting rollers 33. The round balls 34 are rotatably connected to the concave bottom positions of the external threaded grooves of the adjusting rollers 33.

[0074] Specifically, when the adjusting roller 33 contacts and moves on the surface of the photovoltaic panel, the increased frictional force enables the adjusting roller 33 to more powerfully adsorb and remove impurities such as dust and stains on the surface of the photovoltaic panel. For stains with stronger viscosity, there is a certain adhesion force between them and the surface of the photovoltaic panel. The adjusting roller 33 generates a sufficiently large acting force due to the increased frictional force. When this acting force is greater than the adhesion force between the stain and the surface of the photovoltaic panel, the stain can be peeled off from the surface of the photovoltaic panel, thus achieving the purpose of cleaning.

[0075] When the adjusting roller 33 moves on the surface of the photovoltaic panel, the round balls 34 installed at the concave positions of the threaded grooves will roll in the threaded grooves. During the rolling process, the round balls 34 will generate tiny impact forces on the surface of the photovoltaic panel. Stubborn stains usually have a relatively tight attachment structure, and these structures adhere to the surface of the photovoltaic panel by intermolecular forces, electrostatic attraction, etc. The tiny impact forces generated by the rolling of the round balls 34 can destroy these attachment structures, weaken the binding force between the stain molecules, and thus make them easier to be cleaned. For example, some dust particles dried on the surface of the photovoltaic panel will become loose in their attachment to the surface of the photovoltaic panel under the action of the impact force generated by the rolling of the round balls 34, and then can be taken away by the adjusting roller 33.

[0076] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
