Description

Technical Field

[0001] This invention relates to the technical field of photovoltaic equipment accessories, and more particularly to a climate-sensing windproof and dustproof photovoltaic device and its operating method. Background Technology

[0002] As a core area of ​​solar energy utilization, photovoltaic (PV) technology plays a crucial role in the global energy transition due to its clean, flexible, and sustainable characteristics. With the rapid development of the PV industry, the deployment of PV equipment is becoming increasingly widespread, especially in open areas, where the construction of PV power plants has effectively promoted the optimization of local energy structures and environmental improvement. However, while enjoying the convenience brought by PV power generation, the impact of harsh environments such as wind and sandstorms on PV equipment is becoming increasingly prominent.

[0003] Currently, various auxiliary devices for photovoltaic (PV) equipment exist on the market to cope with windy and sandy environments, among which self-cleaning PV equipment is the most common. Self-cleaning PV equipment uses built-in cleaning devices, such as wiping mechanisms or water washing systems, to automatically remove dust from the surface of the PV panels to a certain extent, thereby maintaining the high efficiency of power generation. These devices solve the problem of cleaning PV surfaces to a certain extent and improve the operating efficiency of PV equipment.

[0004] However, existing self-cleaning photovoltaic (PV) devices still exhibit numerous problems and shortcomings when used in harsh environments. Specifically, the complex mechanisms of these devices are susceptible to dust accumulation and contamination in windy and sandy environments, leading to a significant decrease in cleaning efficiency. Furthermore, the physical damage caused by wind and sand to the PV equipment itself cannot be ignored; long-term wind and sand erosion accelerates the aging of the PV panels, shortens the equipment's lifespan, and increases operation and maintenance costs.

[0005] More importantly, most existing self-cleaning photovoltaic devices lack the ability to automatically sense and adapt to environmental changes. During periods of high wind and sand, the devices cannot automatically adjust their operating status to adapt to the environment, which not only affects the power generation efficiency of the devices but may also cause further damage to the devices themselves.

[0006] For example, CN217883305U discloses a dustproof device for photovoltaic power generation modules in a distributed power station. This device achieves automatic adjustment of the photovoltaic panel angle through the cooperation of moving and fixed supports, and is equipped with a dustproof plate and a washing system, which can reduce the impact of dust on the photovoltaic panel to a certain extent. However, this device still has some shortcomings. First, although its dustproof plate can block dust, dust easily accumulates on the surface of the dustproof plate after long-term use, requiring manual cleaning and increasing operation and maintenance costs. Second, the adjustment of the photovoltaic panel angle depends on the mechanical structure, and the adjustment accuracy may decrease due to long-term wear.

[0007] On the other hand, CN220798139U provides a photovoltaic device with dustproof capabilities. This device, through the cooperation of support components and dustproof components, achieves the adjustment of the photovoltaic panel angle and automatic dust removal functions. The dustproof component includes a drive unit, an L-shaped plate, a threaded rod, a cleaning plate, and a fan, which drives the cleaning plate to clean and remove dust, while the fan blows away fine dust. Although this device performs well in dust prevention and removal, its structure is relatively complex. The cleaning plate may exert excessive pressure on the photovoltaic panel, leading to wear and tear and affecting its lifespan. Furthermore, the device's level of intelligence needs improvement; it lacks the ability to automatically sense and adapt to environmental changes.

[0008] In summary, existing self-cleaning photovoltaic (PV) devices suffer from problems such as decreased cleaning efficiency, shortened equipment lifespan, increased operation and maintenance costs, and a lack of environmental change sensing capabilities when dealing with windy and sandy environments. Therefore, developing a PV device auxiliary system capable of automatically sensing environmental changes and making corresponding adjustments has become a crucial issue that urgently needs to be addressed in the current PV technology field. Summary of the Invention

[0009] The technical problem to be solved by this invention is to provide a climate-sensing wind and dust-proof photovoltaic device and its working method, which solves the technical problems faced by photovoltaic equipment when working in harsh environments such as wind and sand, such as poor dust-proof performance, low cleaning efficiency, and lack of environmental change sensing ability. Specifically, although existing self-cleaning photovoltaic equipment can automatically remove dust from the surface of photovoltaic panels to a certain extent, in harsh environments, its complex mechanism is easily jammed and contaminated by dust, resulting in a significant decrease in cleaning efficiency. In addition, most existing dust-proof devices require manual intervention for cleaning and maintenance, which increases operation and maintenance costs. More importantly, most of these devices lack the ability to automatically sense and adapt to environmental changes and cannot automatically adjust their working status according to the size of the wind and sand, thereby affecting the power generation efficiency and service life of the equipment.

The two ends of the rotating shaft are respectively inserted into the machine hole and the limit hole, connecting the drive motor and the photovoltaic panel.

The shaft at the end of the photovoltaic panel also has a hole. The pin is inserted into the pin hole and the hole on the shaft at the end of the photovoltaic panel, connecting the photovoltaic panel and the limit block together.

[0014] In a preferred embodiment, the protective device includes umbrella ribs, buckles, and a pressure plate.

[0016] In a preferred embodiment, the device further includes a wedge, and a wedge hole is provided through the base, through which the wedge passes to fix the base.

[0017] The operating method of the climate-sensing windproof and dustproof photovoltaic device is a method of using the aforementioned climate-sensing windproof and dustproof photovoltaic device, including the following steps: Step 1: When using the equipment for photovoltaic operations in areas with high wind and sand, the equipment is installed using the base. After the equipment is unfolded, the photovoltaic panels on the flipping mechanism are placed in a triangular leaf shape. Multiple devices are placed in a crisscross pattern to fill the gaps and increase the spatial density of the equipment, thereby improving its stability. During this process, the driving device's sensing components sense the climate. In periods of high wind and sand, the sunlight collection rate is also poor. The driving device is activated to raise and lower the equipment, causing it to unfold or retract. Step 2: Driven by the drive device, the support device slides up and down. During the sliding process, the protective device is lifted, exposing the sensing components of the drive device for detection. The photovoltaic panel is lifted by the triangular deformation of the support device, presenting a stable triangular structure for support. Step 3: When the equipment needs protection, the drive device is lowered and the flipping device is activated to flip the photovoltaic panels inward for protection, and dust prevention is carried out in conjunction with the protective device set.

[0018] In the preferred embodiment, the specific operation steps of Step 2 are as follows: when the electric push rod is raised, it drives the column connected to it to slide up and down in the working cavity. The column is limited and stabilized by the shaft hole set on the top shaft frame. After the column is raised, the climate detector is extended to the outside for detection.

[0019] In the preferred embodiment, the specific operation steps of Step 3 are as follows: start the drive motor to rotate on the support plate, drive the rotating shaft connected to it to rotate, thereby rotating the photovoltaic panel and flipping it so that its irradiation surface faces inward, thus improving the dust prevention effect of the equipment against wind and sand.

[0020] The climate-sensing windproof and dustproof photovoltaic device and its working method provided by this invention have the following beneficial effects: 1. This invention solves three major technical pain points of photovoltaic equipment in extreme environments such as wind and sand: poor dustproof performance, low cleaning efficiency, and lack of environmental sensing capability; it overcomes the problems of existing self-cleaning equipment being prone to jamming and contamination in sand and dust, thus avoiding a decrease in cleaning efficiency; it reduces the need for manual intervention and maintenance, thereby lowering operation and maintenance costs; and it enables the equipment to automatically sense and respond to the intensity of wind and sand, thereby improving power generation efficiency and equipment lifespan.

[0021] 2. This invention monitors environmental parameters (such as wind speed and dust concentration) in real time using a climate detector, and links an electric push rod with a drive motor to achieve automatic deployment / retraction of the dustproof device and dynamic adjustment of the photovoltaic panel angle; it is the first to achieve second-level closed-loop control of environmental parameters and equipment actions (response time is reduced by more than 90% compared to traditional manual adjustment), significantly improving the adaptability to harsh environments.

[0022] 3. The three-level protection system of this invention uses dustproof plates and side baffles to block sand and dust; a protective umbrella made of memory material (hard rubber, etc.) covers the photovoltaic panel, which absorbs impact energy through deformation; the tilt design of the photovoltaic panel guides the sand and dust to slide off; the sand and dust adhesion rate and operation and maintenance costs are significantly reduced, and the cleaning efficiency is greatly improved.

[0023] 4. This invention adopts a triangular leaf-shaped layout and a triangular support structure, which utilizes geometric stability to improve impact resistance, significantly reduce wind resistance coefficient and equipment overturning risk, and greatly improve folding speed.

[0024] 5. The electric actuator and drive motor of this invention are integrated into a single design. Through structural optimization, the number of drive components is reduced, improving the reliability of electronic equipment in dusty environments; extending the service life of the equipment and reducing the maintenance cost of the drive system.

[0025] 7. This invention adds warning stickers to the surface of the equipment, which improves visibility at night or in low visibility environments, reduces the risk of collision, significantly improves the safety performance of the equipment, and is suitable for unattended areas.

[0026] 8. The dynamic light-receiving adjustment of the present invention adjusts the angle of the photovoltaic panel in real time through the flipping mechanism, optimizes the light-receiving area, increases the average daily power generation, and shortens the investment return cycle.

[0027] 9. This invention combines intelligent control, three-level protection, and structural innovation, reducing manual intervention, lowering equipment failure rate and maintenance costs, and improving overall economic benefits.

[0028] 10. This invention is the first to apply memory materials such as hard rubber to photovoltaic protection. Through deformation recovery characteristics, it achieves impact resistance and self-repair, extends the fatigue life of the protective umbrella, reduces maintenance costs, improves the stability and power generation efficiency of photovoltaic equipment in extreme environments such as deserts and Gobi, reduces the erosion of equipment by sand and dust, and promotes the large-scale application of renewable energy in harsh environments.

Detailed Implementation

[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments: Example 1 like Figures 1 to 5 As shown, the specific implementation method of the climate-sensing windproof and dustproof photovoltaic device provided by the present invention is as follows.

[0031] The device mainly includes a base 1, a dustproof device, a drive device, a support device, a tilting mechanism, and a protective device. The base 1 provides a stable foundation support for the entire device, and multiple sets of first screw holes 201 are precisely provided on it. These screw holes are used for precise threaded connection with the support device to ensure the stability of the device.

[0032] The dustproof device is evenly and tightly installed on the base 1, including a specially designed dustproof plate. The dustproof plate has a light-transmitting area inside, allowing sunlight to pass through and directly shine on the photovoltaic panel. At the same time, side baffles are welded on both sides of the dustproof plate to effectively prevent dust from entering from the side and keep the photovoltaic panel clean.

[0033] The drive unit is meticulously designed and installed in the middle of the base 1. Its core components include a bracket 301, an electric actuator 302, and a column 303. The electric actuator 302 is cleverly installed in the working cavity 309 within the bracket 301, and its output end is precisely connected to the bottom end of the column 303. Through the smooth lifting and lowering movement of the electric actuator, the column 303 and all components mounted on the column (such as the power supply box 305, signal transmitter 306, assembly 307, and climate sensor 308) can be precisely moved up and down, achieving height adjustment of the device.

[0034] The support device is securely threaded to the base 1 via the first screw hole 201. Its structure includes key components such as a connecting seat 401, a support rod 403, and a connecting rod 404. The two ends of the support rod 403 are flexibly hinged to the connecting seat 401 and the connecting rod 404 via precision-machined lugs 408, forming a stable triangular support structure. A specially designed collar 407 is fitted onto the column 303, with a third mounting seat 409 on the collar. One end of the pull rod 406 is precisely inserted into a slot in the support rod 403 for sliding connection, while the other end is securely connected to the collar 407. When the column 303 moves up and down, the precise transmission of the pull rod 406 drives the support rod 403 to move synchronously, thereby accurately adjusting the tilt angle of the photovoltaic panel to maximize sunlight reception.

[0035] The flipping mechanism achieves a rotational connection with the drive device and support device through the first mounting base 202 and the support plate 405. Its key components include the drive motor 501, the rotating shaft 502, and the photovoltaic panel 503. The drive motor 501 is precisely mounted on the support plate 405 and is firmly connected to the photovoltaic panel 503 via the rotating shaft 502. When the photovoltaic panel needs to be flipped, by precisely controlling the rotation direction and speed of the drive motor 501, the rotating shaft 502 and the photovoltaic panel 503 can be driven to rotate smoothly and accurately, achieving rapid flipping and positioning of the photovoltaic panel. The engagement of the pin 504 with the pin hole 510 and the hole on the shaft at the end of the photovoltaic panel 503 ensures the limiting and stability of the photovoltaic panel 503 during the flipping process, improving the reliability and service life of the entire flipping mechanism.

[0036] The protective device is securely integrated with the drive unit via the column 303, and mainly includes key components such as the umbrella ribs 601, the protective umbrella 602, and the clips 603. The protective umbrella 602 is carefully installed on the umbrella ribs 601 to further protect the photovoltaic panel when the dustproof device retracts. The clips 603 are firmly installed on the lower surface of the limiting block 505 to cooperate with the pressure plate 605 to securely fix the protective umbrella 602. The pressure plate 605 has a through hole 606 in the center, through which it is fitted onto the column 303, and a spring 604 is installed above the pressure plate 605. The spring 604 is fitted onto the column 303, with one end tightly connected to the column 303 and the other end firmly connected to the pressure plate 605, providing additional cushioning and fixation for the protective device.

[0037] In addition, the device includes auxiliary components such as warning stickers 701 and wedges 801. Warning stickers 701 are carefully installed on the outer surface of the protective umbrella 602 to improve the device's visibility, ensuring clear identification even at night or in low visibility conditions. Wedges 801 pass through wedge holes 802 on the base 1 to further secure and reinforce the base, improving the overall stability of the device.

[0038] Through the above detailed and specific description of the embodiments, those skilled in the art can clearly understand the technical solution and device structure of the present invention, and successfully reproduce the climate-sensing windproof and dustproof photovoltaic device of the present invention.

[0039] Example 2 In another preferred embodiment, based on Embodiment 1 above, the working method of the climate-sensing windproof and dustproof photovoltaic device provided by the present invention is specifically implemented as follows: First, when using the device of this invention for photovoltaic operations in areas with high wind and sand, the base 1 must be securely installed in the predetermined position. After the equipment is unfolded, the photovoltaic panels 503 on the flipping mechanism are precisely placed in a triangular leaf shape. This unique placement method not only improves the space utilization and stability of the equipment, but also effectively guides the flow of wind and sand, reducing the direct impact of wind and sand on the equipment.

[0040] Next, the climate sensor 308 in the drive unit senses the external environment in real time and accurately. During periods of strong winds and sandstorms, the sunlight collection rate is affected, and the drive unit needs to be activated for lifting and adjustment. After receiving the command, the electric push rod 302 rises smoothly, driving the column 303 and all components installed on the column (such as the power supply box 305, signal transmitter 306, assembly 307, etc.) to rise synchronously, ensuring that the device reaches the optimal working height.

[0041] As the column 303 rises, the support device also begins precise adjustments. Under the precise pull of the collar 407, the tie rod 406 causes the support rod 403 to gradually unfold, forming a stable triangular support structure that provides solid support for the photovoltaic panel 503. Simultaneously, the flipping mechanism maintains the tilt angle of the photovoltaic panel 503 to maximize sunlight reception and improve power generation efficiency.

[0042] When protection of the equipment is required at night or during periods of heavy sandstorms, the drive mechanism lowers to retract the dustproof device. Upon receiving the command, the electric push rod 302 smoothly retracts, causing the column 303 and all components mounted on it to descend synchronously. During this process, the support device gradually folds under the precise control of the pull rod 406, while the photovoltaic panel 503 precisely flips inward to its protective position via the flipping mechanism, effectively preventing erosion from sandstorms.

[0043] Meanwhile, the protective umbrella 602 in the protective device unfolds precisely under the support of the umbrella ribs 601, providing further protection for the photovoltaic panels. The buckle 603 and the pressure plate 605 cooperate tightly under the action of the spring 604, ensuring the protective umbrella 602 is firmly fixed when the device retracts. The entire protection process is fast and accurate, effectively improving the equipment's survivability and service life in harsh environments.

[0044] Throughout the entire operation, the power supply box 305 provides stable and reliable power support for the equipment, the signal transmitter 306 is responsible for real-time signal transmission and reception, and the assembly 307 centrally processes and analyzes the equipment's data stream, providing decision-making basis for intelligent control. The climate detector 308 continuously and accurately collects and analyzes the external environment, ensuring that the equipment can automatically adjust its working status according to weather changes, achieving intelligent and automated management.

[0045] Through the above detailed and specific description of the working method, those skilled in the art can clearly understand the technical solution and working process of the present invention, and successfully reproduce the working method of the climate-sensing windproof and dustproof photovoltaic device of the present invention.

[0046] In a preferred embodiment, the driving device includes a bracket 301 mounted on the upper plane of the base 1. A working cavity 309 is formed through the bracket 301, and a second mounting base 310 is disposed within the working cavity 309. An electric push rod 302 is mounted on the second mounting base 310, and its output end passes through the second mounting base 310 and connects to the bottom end of the column 303. A slot is provided at the upper end of the bracket 301, and a top shaft bracket 304 is fitted into the slot. A groove 311 is provided on the top shaft bracket 304, and the groove 311 engages with the protrusion of the bracket 301. A shaft hole 312 is provided on the top shaft bracket 304. The column 303 is slidably connected to the shaft hole 312 and the top shaft bracket 304. Multiple sets of mounting slots 313 are provided through the column 303. The power supply box 305, signal transmitter 306, assembly 307 and climate detector 308 are respectively installed in the corresponding mounting slots 313 on the column 303. The above configuration ensures that the components are stably installed while allowing for flexible adjustment of height and angle to meet different environmental monitoring needs. The electric push rod 302 drives the column 303 to rise and fall. The design of the top shaft bracket 304 enhances stability. The overall structure is compact, easy to operate, and improves the efficiency and accuracy of environmental monitoring.

[0047] In a preferred embodiment, the support device includes a connecting seat 401, which is screwed into the base 1 via a first screw 402 and installed in the first screw hole 201. A trunnion is mounted on the connecting seat 401. Ear seats 408 are provided at both ends of the support rod 403. A trunnion is also mounted on the connecting rod 404. Both ends of the support rod 403 are hinged to the connecting seat 401 and the support rod 403 via the ear seats 408 and the trunnion, respectively. A support plate 405 is hinged to the other end of the connecting rod 404. A slot is provided in the middle of the support rod 403. A pull rod is also included. One end of rod 406 is inserted into the slot and slides, while the other end is connected to collar 407. Collar 407 is fitted onto column 303, and a third mounting seat 409 is provided on collar 407. Pull rod 406 is rotatably connected to collar 407 through the third mounting seat 409. The above configuration allows the support device to adjust its angle and height according to actual needs, enhancing the flexibility and stability of the equipment. At the same time, the cooperation of trunnion and hinge enables flexible rotation of support rod and connecting rod, further improving the adaptability and support effect of the entire device.

[0048] In a preferred embodiment, the flipping mechanism includes a drive motor 501, which is mounted on a support plate 405 and connected to a photovoltaic panel 503 via a rotating shaft 502. The support plate 405 has an opening 507, and the photovoltaic panel 503 has a limiting hole 508. Both ends of the rotating shaft 502 pass through the opening 507 and the limiting hole 508, respectively, connecting the drive motor 501 and the photovoltaic panel 503. The other end of the photovoltaic panel 503 is rotatably mounted to a rotating block 506 via a pin through a pin groove 509. The rotating block 506 is rotatably mounted on a first mounting base 202. The rotating block 506 is provided with a pin hole 510, and the shaft at the end of the photovoltaic panel 503 is also provided with a hole. The pin 504 is inserted into the pin hole 510 and the hole on the shaft at the end of the photovoltaic panel 503, connecting the photovoltaic panel 503 and the limiting block 505 together. The above arrangement ensures that the photovoltaic panel 503 can be rotated smoothly under the drive of the drive motor 501. Through the cooperation of the pin shaft and the pin groove 509 and the pin 504 and the pin hole 510, the limiting and stability of the photovoltaic panel 503 during the rotation process are realized, which improves the reliability and service life of the entire rotation mechanism.

[0049] In a preferred embodiment, the protective device includes an umbrella rib 601, a buckle 603, and a pressure plate 605. One end of the umbrella rib 601 is connected to the upright 303, and the other end is fitted with a protective umbrella 602. The buckle 603 is installed on the lower surface of the limiting block 505. The pressure plate 605 has a through hole 606 in the middle, through which it is fitted onto the upright 303. A spring 604 is installed above the pressure plate 605, fitted onto the upright 303, with one end connected to the upright 303 and the other end connected to the pressure plate 605. The above configuration provides... The protective umbrella 602 is made of memory materials such as hard rubber, which can effectively block the erosion of the photovoltaic panel by wind and sand, and also has a certain impact resistance to protect the photovoltaic panel from accidental collisions. The cooperation between the buckle 603 and the pressure plate 605 ensures that the protective umbrella 602 is firmly fixed when the device is retracted, and avoids the protective umbrella from falling off accidentally in windy and sandy weather. The addition of the spring 604 provides an additional cushioning effect, further enhancing the stability and durability of the device.

[0050] In a preferred embodiment, the device further includes a warning sticker 701, which is installed on the outer surface of the protective umbrella 602. The warning sticker 701 is designed to be conspicuous, alerting people in the vicinity to the device's operating status or potential dangers, thereby enhancing safety. At the same time, the warning sticker 701 is made of waterproof and wear-resistant material to ensure long-term effectiveness.

[0051] In a preferred embodiment, the device further includes a wedge 801, and a wedge hole 802 is provided through the base 1. The wedge 801 passes through the corresponding wedge hole 802 to fix the base 1. The above configuration enables the device to achieve stable installation of the base 1 under different ground conditions by adjusting the position of the wedge 801 in the wedge hole 802 according to different installation requirements, thereby enhancing the adaptability and stability of the device.

[0052] In the preferred embodiment, the specific operation steps of Step 2 are as follows: when the electric push rod 302 rises, it drives the column 303 connected to it to slide up and down within the working cavity 309. The column 303 is limited and stabilized by the shaft hole 312 provided on the top shaft bracket 304. After the column 303 rises, the climate detector 308 extends to the outside for detection. The above settings not only ensure that the climate detector 308 can extend and be positioned accurately and stably, but also realize real-time monitoring of the climate environment through the precise control of the electric push rod 302, which greatly improves the detection efficiency and the accuracy of the data.

[0053] In the preferred embodiment, Step 3 involves starting the drive motor 501, causing it to rotate on the support plate 405, which in turn drives the connected shaft 502 to rotate. Consequently, the photovoltaic panel 503 rotates, flipping it so that its irradiation surface faces inward, thus improving the equipment's dustproof effect against wind and sand. This setup ensures that the photovoltaic panel is effectively protected under different wind conditions. Simultaneously, the intensity of wind and sand can be monitored in real time by sensors, and the rotation angle can be automatically adjusted to further optimize dustproof performance, ensuring power generation efficiency and equipment lifespan.

[0054] This invention provides a climate-sensing wind and dust prevention photovoltaic device and its operating method, offering an innovative solution to the technical problems faced by photovoltaic equipment operating in harsh environments such as wind and sandstorms, including poor dust prevention performance, low cleaning efficiency, and lack of environmental change sensing capabilities. Specifically, this invention solves the problem of significantly reduced cleaning efficiency of self-cleaning photovoltaic equipment in harsh environments, as well as the problems of traditional dust prevention devices requiring manual intervention and incurring high operation and maintenance costs. Furthermore, this invention overcomes the shortcomings of existing equipment in lacking automatic sensing and adaptability to environmental changes.

[0055] This invention integrates multiple functions such as climate sensing, automatic deployment and retraction, and wind and dust protection, providing comprehensive protection for photovoltaic equipment in harsh environments. The device employs a unique triangular leaf-shaped photovoltaic panel 503 placement method, combined with a triangular support structure, which not only improves the space utilization and stability of the equipment but also effectively guides the flow of wind and sand, reducing the direct impact of wind and sand on the equipment. The protective device innovatively uses shape-memory materials such as hard rubber as a protective umbrella, which effectively blocks wind and sand while also possessing a certain degree of impact resistance, providing more comprehensive and effective protection for photovoltaic equipment.

[0056] Furthermore, by introducing climate sensing technology, this invention enables photovoltaic equipment to automatically sense and respond to changes in the external environment, adjusting its operating status according to weather conditions, thus improving the equipment's intelligence and automation level. This innovative design not only improves the efficiency and lifespan of photovoltaic equipment in harsh environments but also provides new ideas and methods for the development of the photovoltaic industry, possessing significant innovative value and application prospects.

[0057] In summary, this invention provides new solutions and technical support for the application of photovoltaic equipment in harsh environments, and is an important force driving technological progress and development in the photovoltaic industry.
