DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, and not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0029] Please refer to​​Figures 1 to 3 , Figure 1 is a whole schematic view of the power generation structure provided by the embodiment of the utility model, Figure 2 is the power generation structure provided by the embodiment of the utility model, Figure 1 is a local enlarged view of the A area in the power generation structure, Figure 3 is a sectional view of the power generation structure along the direction of the flow cavity 12.

[0030] The embodiment of the utility model provides a kind of power generation structure, it is aimed at by low cost, fast and effective way clean power generation plate 20 surface, and will not damage power generation plate 20.

[0031] The power generation structure includes outer frame 10 and power generation plate 20, wherein outer frame 10 is enclosed to form an enclosed cavity 11, can accommodate power generation plate 20 and provide protection for it. Outer frame 10 is designed with flow cavity 12 inside, flow cavity 12 is connected with external equipment by input port 13, and the function of input port 13 is used to introduce liquid (such as water) or airflow. By this structure, external equipment can inject liquid or airflow into flow cavity 12, to provide necessary power source for the cleaning of power generation plate 20.

[0032] It is worth noting that the side of outer frame 10 close to enclosed cavity 11 is provided with guide-through port 14, and the function of guide-through port 14 is to realize the fluid or gas flow between enclosed cavity 11 and flow cavity 12. Through guide-through port 14, water flow or airflow input into flow cavity 12 can flow into enclosed cavity 11 smoothly, and contact power generation plate 20 surface, effectively clean. In the cleaning process, liquid or airflow can remove dust, dirt or other pollutants on the surface of power generation plate 20, to restore the photoelectric conversion efficiency of power generation plate 20.

[0033] In the embodiment, the application forms enclosed cavity 11 by outer frame 10 to carry and protect power generation plate 20, and can easily access water source or airflow by flow cavity 12 and input port 13, without manual operation or additional complex cleaning equipment. In addition, flow cavity 12 and enclosed cavity 11 are communicated through guide-through port 14, so that liquid or gas can directly contact the surface of power generation plate 20, play a cleaning role, thereby greatly improving the efficiency of power generation plate 20, prolonging the service life of the system, reducing the frequent maintenance and cost required by traditional cleaning method. In the cleaning process, damage to the surface of power generation plate 20 is avoided.

[0034] Further, in the embodiment of the application, in order to enhance the cleaning effect and improve the uniformity of fluid or gas distribution, the application surrounds flow cavity 12 around power generation plate 20. Under this layout, flow cavity 12 can make water flow or airflow to clean the surface of power generation plate 20 comprehensively, to ensure that each area of power generation plate 20 can be fully cleaned, especially in the edge and corner of power generation plate 20 where dust is easy to accumulate.

[0035] At the same time, in order to make the liquid or gas more evenly distributed to the surface of the power generation plate 20, the number of the through ports 14 is designed to be not less than two, and the through ports 14 are arranged at the side of the outer frame 10 close to the enclosed cavity 11. The arrangement of multiple through ports 14 can ensure that after the liquid or gas is input into the overflow cavity 12, it can flow into the enclosed cavity 11 from multiple outlets at the same time, thereby realizing more extensive and more uniform cleaning coverage.

[0036] In the embodiment, the overflow cavity 12 provides an optimized path for the liquid or gas flow through the ring-shaped layout, effectively avoiding local accumulation or waste of the fluid or gas, and further improving the cleaning effect of the surface of the power generation plate 20. The arrangement of multiple through ports 14 avoids the problem of uneven cleaning that may be caused by liquid or gas flowing in from only one through port 14, and ensures that each part of the power generation plate 20 can obtain a relatively uniform cleaning effect during the cleaning process.

[0037] Further, in order to optimize the cleaning effect, the distance between adjacent through ports 14 is set to be equal in the embodiment of the application. This avoids excessive concentration of fluid or gas flow in certain areas, thereby improving the overall efficiency and uniformity of the cleaning process.

[0038] Specifically, the equal distance between adjacent through ports 14 enables the fluid or gas flow to be relatively evenly distributed inside the enclosed cavity 11 when flowing out of each through port 14, so that the liquid or gas flow can uniformly cover each area of the power generation plate 20, especially for those areas that are prone to dust accumulation, such as the corners and edges of the power generation plate 20, which can be more effectively cleaned, preventing insufficient cleaning in certain parts.

[0039] In the embodiment, the equal distance between adjacent through ports 14 effectively avoids local congestion or poor flow of water or gas flow caused by unreasonable layout of the through ports 14. Moreover, the equal distance arrangement of the through ports 14 makes the overall structure of the outer frame 10 more symmetrical and stable, which helps to improve the overall performance and reliability of the system. In addition, the uniform spacing can simplify the structural arrangement and manufacturing process of the equipment.

[0040] Please refer to Figure 4 , Figure 4 is another power generation structure provided by the embodiment of the utility model along the direction perpendicular to the cross-sectional view of the overflow cavity 12.

[0041] In some embodiments, in order to realize the cleaning work on both sides of the power generation plate 20 simultaneously, the through port 14 comprises a first port 141 and a second port 142, which are respectively communicated with the flow cavity 12. And the first port 141 and the second port 142 are designed on the opposite sides of the power generation plate 20, so that the liquid or gas flow can enter the enclosed cavity 11 from the two ports simultaneously and be evenly distributed to the two sides of the power generation plate 20, thereby improving the cleaning efficiency and ensuring that the surface of the power generation plate 20 is fully cleaned.

[0042] Specifically, the first port 141 and the second port 142 are respectively located on the two sides of the power generation plate 20, and the liquid or gas flow enters the flow cavity 12 from the first port 141, then enters the enclosed cavity 11 through the through port 14, and is sprayed to one side of the power generation plate 20, while the second port 142 plays a similar role and sprays liquid or gas flow to the other side of the power generation plate 20. The water flow or gas flow can act on the power generation plate 20 from both sides simultaneously during the cleaning process, effectively improving the cleaning coverage.

[0043] In the embodiment, by locating the first port 141 and the second port 142 on the opposite sides of the power generation plate 20, the power generation structure can simultaneously clean the two sides of the power generation plate 20. The liquid or gas flow acting on the front surface of the power generation plate 20 can quickly and effectively remove dust and dirt, restore the light transmittance of the photovoltaic cell, and thereby improve the power generation efficiency.

[0044] The liquid or gas flow acting on the back surface of the power generation plate 20 can timely remove dust and ensure the smoothness of the back surface heat dissipation channel, avoiding the occurrence of heat accumulation and overheating problems. During the cleaning process, the gas flow or water flow not only removes dust, but also accelerates heat dissipation through dynamic flow action, effectively preventing overheating caused by poor heat dissipation and maintaining a good working temperature of the power generation plate 20.

[0045] Please refer to Figure 4 and Figure 5 , Figure 4 is another power generation structure provided by the embodiment of the utility model along the vertical direction of the flow cavity 12, Figure 5 is a partial enlarged view of the B area in Figure 4 .

[0046] Further, in some embodiments, the power generation structure further comprises a partition plate 30, which is arranged in the flow cavity 12 and divides the flow cavity 12 into two independent flow channels: a first flow channel 121 and a second flow channel 122. The first flow channel 121 and the second flow channel 122 are respectively located on the two sides of the partition plate 30. The first port 141 is connected with the first flow channel 121, and the second port 142 is connected with the second flow channel 122. The first port 141 and the second port 142 are respectively communicated with the respective flow channels and communicated with the enclosed cavity 11, realizing the spraying and cleaning effect of the liquid or gas.

[0047] In one aspect, the partition 30 enables the first port 141 and the second port 142 to work independently. In practical applications, sometimes only one side of the power generation plate 20 needs to be cleaned, and the other side does not need to be cleaned. In this case, through the design of the partition 30, the first port 141 and the second port 142 can work independently, so that only one side of the fluid or air flow is cleaned, and the other side remains static and is not disturbed. This independent working mechanism not only improves the flexibility of the cleaning process, but also saves the use of water sources or air flow, reduces unnecessary waste, and further reduces operating costs.

[0048] On the other hand, the presence of the partition 30 not only helps to separate the structure and guide the flow channel, but also can control the flow of fluid or air flow by adjusting its position. Specifically, by adjusting the position layout of the partition 30, the cross-sectional area of the first flow channel 121 and the second flow channel 122 can be changed, thereby controlling the flow of liquid or air flow into the respective flow channels. The adjustment mechanism enables users to flexibly adjust the flow according to actual needs, thereby accurately controlling the cleaning effect.

[0049] In this embodiment, the partition 30 separates the overflow cavity 12 into the first flow channel 121 and the second flow channel 122, not only enabling the first port 141 and the second port 142 to work independently, increasing the flexibility and functionality of the power generation structure, but also accurately adjusting the flow distribution, optimizing the cleaning effect, reducing the waste of fluid or air flow, and improving the economic efficiency and cleaning efficiency of the system.

[0050] Please refer to Figure 6 , Figure 6 is a whole schematic diagram of the power generation system provided by the embodiment of the utility model.

[0051] The embodiment of the utility model further provides a power generation system, which comprises a plurality of the above-mentioned power generation structures and a cleaning assembly 40. The cleaning assembly 40 is connected with the overflow cavity 12 of each power generation structure and is responsible for efficiently cleaning the plurality of power generation structures.

[0052] Specifically, the plurality of power generation structures in the power generation system can be connected with the cleaning assembly 40 through pipes or other connection modes. The cleaning assembly 40 uniformly and efficiently delivers cleaning fluid (such as water or air) to the overflow cavity 12 of the plurality of power generation structures, and fully and uniformly cleans each power generation plate 20.

[0053] In the present embodiment, the cleaning assembly 40 is capable of performing cleaning on multiple power generation panels 20. Generally, there are three starting strategies, the first mode: combined with the current weather, light intensity and power generation power curve, intelligent judgment is performed to identify the current solar power generation panel 20 dust coverage rate curve. When the dust coverage rate is detected to be more than 95%, the power generation system automatically starts the self-cleaning function; the second mode: according to the local wind and sand conditions and the daily inspection results, the self-cleaning frequency is set, for example, it can be set to once a day or once a week, which is suitable for areas with relatively fixed environmental conditions; the third mode: manual start cleaning, which is suitable for special circumstances where special attention is needed to clean some power generation panels 20 or areas.

[0054] In some embodiments, the cleaning assembly 40 includes a water washing structure 41 and a wind drying structure 42 to complete the cleaning and drying of the power generation panel 20 simultaneously during the cleaning process. The cooperation of the water washing structure 41 and the wind drying structure 42 can significantly improve the cleaning efficiency and recovery ability of the solar power generation panel 20, ensuring that the surface of the power generation panel 20 remains clean and quickly recovers its power generation function.

[0055] Specifically, the water washing structure 41 includes a water pump 411 and a water delivery pipe 412. The water delivery pipe 412 connects the water pump 411 and the flow cavity 12. The water pump 411 is used to provide the required water flow, which is delivered to the flow cavity 12 of each power generation structure through the water delivery pipe 412 to act on the surface of the power generation panel 20 for cleaning. The power generation panel 20 is efficiently cleaned by the jetting water flow, removing dust, dirt and other contaminants on the surface of the power generation panel 20 to restore its good photoelectric conversion efficiency.

[0056] The wind drying structure 42 includes a fan 421 and an air guide pipe 422, and the air guide pipe 422 connects the fan 421 and the flow cavity 12. The fan 421 is used to generate strong air flow, and the air guide pipe 422 is responsible for delivering the air flow to the inside of the flow cavity 12 of each power generation structure. After cleaning is completed, the wind drying structure 42 will start to deliver air flow through the air guide pipe 422 to the surface of the power generation panel 20 to quickly evaporate and blow away the water, thereby accelerating the drying process of the power generation panel 20. The fan 421 can adjust the wind speed and air volume according to the weather conditions to ensure that the power generation panel 20 can be dried and restored to normal operation in the shortest time.

[0057] In the present embodiment, the combination of the water washing structure 41 and the wind drying structure 42 can first perform water washing cleaning and then quickly dry the power generation panel 20 through the wind drying structure 42 in a complete cleaning cycle. The dual process of cleaning and drying not only effectively removes surface dirt, but also maintains the smoothness of the surface of the power generation panel 20, preventing water accumulation from causing corrosion or electrical problems. The effective cooperation of the water washing and wind drying functions makes the entire cleaning process more efficient, rapid and greatly reduces the damage to the power generation panel 20.

[0058] Further, in some embodiments, the cleaning assembly 40 further comprises a one-way valve 43, which is arranged in the water delivery pipe 412 and the air delivery pipe 422, in the connection passage between the water pump 411 or the air fan 421 and the flow passage 12. The one-way valve 43 functions to ensure that the liquid or gas flow is allowed to flow in one direction only, i.e. the liquid or gas flow can only flow from the water pump 411 or the air fan 421 to the flow passage 12, but not in the reverse direction, thereby ensuring efficient operation of the system and preventing potential problems caused by backflow.

[0059] When the water pump 411 or the air fan 421 starts to operate, the one-way valve 43 will automatically open to allow the water flow or air flow to flow along the set path to the flow passage 12, into the area where the power generation panels 20 are located for cleaning or air drying. However, once the water pump 411 or the air fan 421 stops operating, the one-way valve 43 will automatically close to prevent the liquid or gas flow from flowing back in the reverse direction, ensuring that the liquid or gas in the system will not flow back into the water pump 411 or the air fan 421, avoiding damage to the equipment or reduction in efficiency due to backflow.

[0060] In this embodiment, the one-way valve 43 is arranged in the connection passage (water delivery pipe 412 and air delivery pipe 422) between the water pump 411 or the air fan 421 and the flow passage 12, which can prevent the cleaning liquid or air flow from flowing back into the pipeline system, causing instability of the internal pressure of the system, enhancing the safety and reliability of the system. At the same time, the one-way valve 43 ensures the stability of the liquid or gas flow during the cleaning process, so that the output of the water pump 411 and the air fan 421 can be focused on delivering the cleaning liquid or gas directly to the target area, without worrying about energy waste or flow instability caused by backflow.

[0061] In some embodiments, the cleaning assembly 40 further comprises a flow distribution structure 44, which comprises a flow collecting pipe 441 and a plurality of flow distribution pipes 442, the flow collecting pipe 441 being connected to the water delivery pipe 412 and the air delivery pipe 422, through this arrangement, the water washing structure 41 and the air drying structure 42 can share a set of pipeline system connected to the power generation structure, thereby realizing the simplification of the system pipeline and the maximization of resource utilization.

[0062] Specifically, the flow collecting pipe 441 is connected to the water delivery pipe 412 of the water washing structure 41 and the air delivery pipe 422 of the air drying structure 42, the flow collecting pipe 441 can simultaneously access two different types of fluid or gas (liquid and air) and guide the water and air flow into different flow distribution pipes 442 through its internal passage. The pipe diameter and flow passage layout of the flow collecting pipe 441 are designed according to the requirements of water flow and air flow, to ensure efficient flow of water and air and connection to the flow passage 12 of the power generation structure.

[0063] The shunt pipes 442 are connected to the manifold pipe 441 at one end and to the input port 13 at the other end. Each shunt pipe 442 is responsible for directing water flow or air flow to a different power generation structure. The number and length of the shunt pipes 442 are optimized according to the number and layout of the power generation panels 20 in the system, ensuring that each power generation panel 20 receives appropriate cleaning and drying treatment.

[0064] In this embodiment, the shunt structure 44 allows the water washing structure 41 and the air drying structure 42 to share a set of pipes for connecting to the power generation structures through the configuration of the manifold pipe 441 and the shunt pipes 442. This avoids arranging a separate piping system for each function (cleaning and drying), reducing the complexity of the system and the cost of materials and installation. The shared piping scheme not only saves space for piping arrangement, but also reduces the difficulty of maintenance and repair.

[0065] Furthermore, the arrangement of the shunt structure 44 allows the water washing and air drying functions to work independently or simultaneously as needed, effectively controlling the distribution of water flow and air flow to ensure that the cleaning and drying processes can adapt to different working environments and the state of the power generation panels 20.

[0066] Further, to precisely regulate the flow in each shunt pipe 442, the cleaning assembly 40 further comprises a plurality of control valves 45, each of which is arranged on a shunt pipe 442. Each control valve 45 functions independently to precisely control the flow of fluid in the shunt pipe 442. At the same time, by adjusting the control valves 45, the flow rate of the liquid or air flow in each shunt pipe 442 can also be regulated. According to the needs of different power generation panels 20, the intensity and duration of water flow and air flow can be precisely adjusted to ensure that each power generation structure receives appropriate cleaning and drying treatment.

[0067] In this embodiment, each shunt pipe 442 is equipped with a control valve 45, which is used to adjust each shunt pipe 442 individually, allowing the cleaning of the power generation structure connected to a specific shunt pipe 442 to be controlled, thereby saving resources. Furthermore, the flow rate of each shunt pipe 442 can be adjusted individually according to cleaning needs or the state of the power generation panels 20. For example, for some heavily polluted areas, the water flow rate can be increased for stronger flushing, while for other less polluted areas, the flow rate can be reduced to avoid wasting water or air flow. The independence of the control valves 45 allows the system to be more flexible in responding to different working conditions.

When an element is referred to as "connected to" another element, it can be directly connected to another element or indirectly connected to another element through a middle element.
