Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary devices for photovoltaic equipment, and particularly to a climate-sensing wind and dust-proof photovoltaic device and its working method. Background Art

[0002] As the core field of solar energy utilization, photovoltaic technology plays a crucial role in the global energy transition with its clean, flexible, and sustainable characteristics. With the rapid development of the photovoltaic industry, the deployment scope of photovoltaic equipment is becoming increasingly extensive. Especially in open areas, the construction of photovoltaic power stations has effectively promoted the optimization of the local energy structure and the improvement of the environment. However, while enjoying the convenience brought by photovoltaic power generation, the impact of harsh environments such as wind and sand on photovoltaic equipment has become increasingly prominent.

[0003] Currently, there are already various auxiliary devices for photovoltaic equipment used to cope with the wind and sand environment in the market. The most common one is the self-cleaning photovoltaic equipment. Through built-in cleaning devices such as wiping mechanisms or water washing systems, the self-cleaning photovoltaic equipment can automatically remove the dust on the surface of the photovoltaic panel to a certain extent, thereby maintaining the high-efficiency power generation of the photovoltaic panel. These devices have solved the cleaning problem of the photovoltaic surface to a certain extent and improved the operation efficiency of the photovoltaic equipment.

[0004] However, during the use of existing self-cleaning photovoltaic equipment in harsh environments, many problems and deficiencies have still emerged. Specifically, the complex mechanisms of self-cleaning photovoltaic equipment are prone to being stuck and polluted by dust in the wind and sand environment, resulting in a significant decrease in cleaning efficiency. In addition, the physical damage of the wind and sand to the photovoltaic equipment itself cannot be ignored. Long-term wind and sand erosion will accelerate the aging of the photovoltaic panel, shorten the service life of the equipment, and increase the operation and maintenance costs.

[0005] More importantly, most of the existing self-cleaning photovoltaic equipment lacks the ability to automatically sense and adapt to environmental changes. During periods with strong wind and sand, the equipment cannot automatically adjust its working state to adapt to the environment, which not only affects the power generation efficiency of the equipment but may also cause further damage to the equipment itself.

[0006] For example, CN217883305U discloses a dust-proof device for photovoltaic power generation components in a distributed power station. Through the cooperation of a movable support rod and a fixed support rod, the device realizes the automatic adjustment of the angle of the photovoltaic panel and is equipped with a dust-proof plate and a flushing system, which can reduce the impact of dust on the photovoltaic panel to a certain extent. However, this device still has some deficiencies. First, although the dust-proof plate can block dust, the surface of the dust-proof plate is prone to dust accumulation after long-term use and requires manual cleaning, increasing the operation and maintenance costs. Second, the adjustment of the angle of the photovoltaic panel depends on the mechanical structure, and the adjustment accuracy may decrease due to long-term wear.

[0007] On the other hand, for example, CN220798139U provides a photovoltaic device with a dust-proof effect, which realizes the adjustment of the angle of the photovoltaic panel and the automatic cleaning and dust removal function through the cooperation of the support component and the dust-proof component. Among them, the dust-proof component includes a drive part, an L-shaped plate, a threaded rod, a cleaning brush plate and a fan, which can drive the cleaning brush plate to clean and remove dust, and cooperate with the fan to blow off fine dust. Although the device performs well in dust prevention and dust removal, its structure is relatively complex, and the cleaning brush plate may cause excessive pressure on the photovoltaic panel, causing wear of the photovoltaic panel and affecting its service life. In addition, the intelligence level of the equipment needs to be improved, and it lacks the ability to automatically sense and adapt to environmental changes.

[0008] In summary, existing self-cleaning photovoltaic systems face challenges in windy and sandy environments, including reduced cleaning efficiency, shortened equipment lifespan, increased maintenance costs, and a lack of environmental sensing capabilities. Therefore, developing a photovoltaic device accessory that can automatically sense environmental changes and adapt accordingly has become a critical challenge in the photovoltaic technology landscape.

Specifically, although the self-cleaning photovoltaic equipment in the existing technology can automatically remove dust from the surface of the photovoltaic panel to a certain extent, in harsh environments, its complex structure is easily stuck and contaminated by dust, resulting in a significant decrease in cleaning efficiency; in addition, most of the 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 the working state according to the size of the wind and sand, thereby affecting the power generation efficiency and service life of the equipment.

[0017] The working method of the climate-sensing wind and dust-proof photovoltaic device is a method of using the above-mentioned climate-sensing wind and dust-proof photovoltaic device for work, including the following steps: Step1: During the process of using the device for photovoltaic operations in areas with strong wind and sand, install the device through the base. After the device is unfolded, the photovoltaic panels on the flipping mechanism are placed in a triangular leaf shape. By placing multiple devices crosswise to make up for the gaps, the spatial density of the device is increased to improve the stability of the device. During this process, the climate is sensed by the sensing component of the driving device. During periods with strong wind and sand, the sunlight collection rate is also relatively poor. By starting the driving device to lift or lower, the device is driven to unfold or contract; Step2: Driven by the driving device, the supporting device slides up and down. During the sliding process, the protective device is driven to rise, exposing the sensing component of the driving device for detection. The photovoltaic panels are lifted by the deformation of the triangular structure of the supporting device, presenting a triangular stable structure for support; Step3: When the device needs protection, lower the driving device, start the flipping device to flip the photovoltaic panels inward for protection, and cooperate with the protective device to be sleeved for dust-proof treatment.

[0018] In a preferred solution, the specific operation steps of Step2 are as follows: when the electric push rod rises, it drives the connected column to lift and slide in the working cavity, and limits and stabilizes the column in cooperation with the shaft hole provided on the top shaft frame. After the column rises, the climate detector is extended to the outside for detection.

[0019] In a preferred solution, the specific operation steps of Step3 are as follows: start the driving motor to rotate on the support plate, drive the connected rotating shaft to rotate, and thus the photovoltaic panels rotate accordingly. By flipping, the irradiation surface faces inward, improving the dust-proof effect of the device against wind and sand.

[0020] The climate-sensing wind and dust-proof photovoltaic device and its working method provided by the present invention have the following beneficial effects: 1. The present invention solves the three major technical pain points of poor dust-proof performance, low cleaning efficiency, and lack of environmental sensing ability of photovoltaic devices in extreme environments such as wind and sand; overcomes the problems of easy jamming and pollution of existing self-cleaning devices in sand and dust, avoiding the decline in cleaning efficiency; reduces the need for manual intervention and maintenance, and reduces the operation and maintenance costs; realizes the automatic perception and response of the device to the wind and sand intensity, and improves the power generation efficiency and the service life of the device.

[0021] 2.

It is the first time to achieve second-level closed-loop control of environmental parameters and equipment actions (the response time is shortened by more than 90% compared with traditional manual adjustment), significantly improving the ability to adapt to harsh environments.

[0022] 3. The three-level protection system of the present invention includes dust panels and side baffles to block sand and dust; a memory material protective umbrella (such as hard rubber) covers the photovoltaic panel and absorbs impact energy through deformation; the inclination design of the photovoltaic panel guides the wind and sand to slide down; the dust adhesion rate and operation and maintenance costs are significantly reduced, and the cleaning efficiency is greatly improved.

[0023] 4. The present invention adopts a triangular leaf layout and a triangular support structure, and uses geometric stability to improve impact resistance. The wind resistance coefficient and the risk of equipment overturning are significantly reduced, and the folding speed is greatly improved.

[0024] 5. The integrated design of the electric push rod and the drive motor of the present invention reduces the number of drive components through structural optimization, thereby 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. The present invention adds a warning sticker on the surface of the equipment to improve recognition at night or in low-visibility environments, reduce the risk of collision, and significantly improve the safety performance of the equipment, making it suitable for unmanned areas.

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

Detailed implementation manners

[0030] The technical solutions in the present invention will be further described below with reference to the drawings and embodiments: Embodiment 1 As Figures 1 to 5 shown, the climate-sensing wind and dust-proof photovoltaic device provided by the present invention is specifically implemented as follows.

[0031] The device mainly includes a base 1, a dust-proof device, a driving device, a support device, a flipping mechanism and a protection device. The base 1 provides a stable basic support for the entire device, and is precisely provided with multiple groups of first screw holes 201 thereon, which are used for precise threaded connection with the support device to ensure the stability of the device.

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

[0033] The driving device is carefully designed and installed in the middle of the base 1. Its core components include a bracket 301, an electric push rod 302, and a column 303. The electric push rod 302 is ingeniously installed in the working cavity 309 inside the bracket 301, and its output end is precisely connected to the bottom end of the column 303. Through the smooth lifting movement of the electric push rod, it can accurately drive the column 303 and all components installed on the column (such as the power supply box 305, signal transmitter 306, assembly unit 307, and climate detector 308, etc.) to move up and down, realizing the height adjustment of the device.

[0034] The supporting device is firmly connected to the base 1 through 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. Both ends of the support rod 403 are flexibly hinged to the connecting seat 401 and the connecting rod 404 through precisely machined ear seats 408, thus forming a stable triangular support structure. A special collar 407 is sleeved on the column 303, and a third mounting seat 409 is arranged on the collar. One end of the pull rod 406 is precisely inserted into the slotted opening of the support rod 403 to achieve a sliding connection, and the other end is firmly connected to the collar 407. When the column 303 moves up and down, through the precise transmission of the pull rod 406, it can drive 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 realizes the rotational connection with the driving device and the supporting device through the first mounting seat 202 and the support plate 405. Its key components include a driving motor 501, a rotating shaft 502, and a photovoltaic panel 503, etc. The driving motor 501 is precisely installed on the support plate 405 and is firmly connected to the photovoltaic panel 503 through the rotating shaft 502. When it is necessary to flip the photovoltaic panel, by precisely controlling the rotation direction and speed of the driving motor 501, it can drive the rotating shaft 502 and the photovoltaic panel 503 to rotate smoothly and accurately, realizing the rapid flipping and positioning of the photovoltaic panel; the cooperation of the pin 504 with the pin hole 510 and the hole on the end shaft of the photovoltaic panel 503 realizes the limit and stability of the photovoltaic panel 503 during the flipping process, improving the reliability and service life of the entire flipping mechanism.

[0036] The protection device is stably and integrally installed with the driving device through the column 303, and mainly includes key components such as umbrella ribs 601, protection umbrella 602, and buckle 603. The protection umbrella 602 is carefully installed on the umbrella ribs 601 to further protect the photovoltaic panel when the dust protection device contracts. The buckle 603 is firmly installed on the lower plane of the limit block 505 and is used to cooperate with the pressure plate 605 to firmly fix the protection umbrella 602. A through hole 606 is provided in the middle of the pressure plate 605, and it is sleeved on the column 303 through this through hole, and a spring 604 is installed above the pressure plate 605. The spring 604 is sleeved on the column 303, one end of which is tightly connected to the column 303, and the other end is firmly connected to the pressure plate 605, providing additional buffering and fixing effects for the protection device.

[0037] In addition, the device also includes auxiliary components such as warning stickers 701 and wedges 801. The warning stickers 701 are carefully installed on the outer surface of the protection umbrella 602 to improve the recognition of the device and ensure that it can be clearly identified at night or in low visibility conditions. The wedge 801 passes through the wedge hole 802 on the base 1 to further fix and reinforce the base and improve the overall stability of the device.

[0038] Through the above detailed and specific implementation descriptions, those skilled in the art can clearly understand the technical solutions and device structures of the present invention and successfully reproduce the climate-sensing wind and dust protection photovoltaic device of the present invention.

[0039] Embodiment 2 In another preferred embodiment, on the basis of the above Embodiment 1, the working method of the climate-sensing wind and dust protection photovoltaic device provided by the present invention is specifically implemented as follows: First, when using the device of the present invention for photovoltaic operations in areas with strong wind and sand, the base 1 needs to be stably installed at a predetermined position. After the device is unfolded, the photovoltaic panel 503 on the flipping mechanism is accurately placed in the form of a triangular leaf. This unique placement method not only improves the space utilization rate and stability of the device but also effectively guides the flow direction of the wind and sand, reducing the direct impact of the wind and sand on the device.

[0040] Then, the external environment is sensed in real time and accurately through the climate detector 308 in the driving device. During periods with strong wind and sand, since the sunlight collection rate is affected, the driving device needs to be started for lifting adjustment at this time. After receiving the instruction, 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 unit 307, etc.) to rise synchronously to ensure that the device reaches the optimal working height.

[0041] As pillars 303 rise, the support mechanism begins precise adjustments. Pulling rods 406, precisely pulled by collars 407, gradually unfold support rods 403, forming a stable triangular support structure that provides solid support for photovoltaic panels 503. Simultaneously, a tilting mechanism maintains the tilt angle of photovoltaic panels 503, maximizing sunlight absorption and improving power generation efficiency.

[0042] When equipment protection is needed at night or during periods of particularly strong sandstorms, the drive mechanism descends, causing the dust shield to retract. Upon receiving the command, the electric actuator 302 smoothly retracts, simultaneously lowering the column 303 and all components mounted thereon. During this process, the support mechanism gradually folds under the precise guidance of the pull rod 406, and the photovoltaic panel 503 is precisely tilted inwards by the tilting mechanism to a protective position, effectively protecting it from wind and sand erosion.

[0043] At the same time, the protective umbrella 602 in the protective device precisely unfolds, supported by the ribs 601, to further protect the photovoltaic panels. The buckle 603 and the pressure plate 605, driven by the spring 604, tightly cooperate to ensure that the protective umbrella 602 is firmly fixed when the device is retracted. The entire protective process is fast and accurate, effectively improving the device's survivability and service life in harsh environments.

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

[0045] Through the above detailed and specific description of the working method, professional and technical personnel in this field can clearly understand the technical solution and work flow of the present invention, and successfully reproduce the working method of the climate-sensitive wind-proof and dust-proof photovoltaic device of the present invention.

A shaft hole 312 is provided on the top shaft bracket 304. The column 303 passes through the shaft hole 312 and is slidably connected to the top shaft bracket 304. A plurality of mounting grooves 313 are disposed through the column 303. The power supply box 305, the signal transmitter 306, the assembly unit 307 and the climate detector 308 are respectively installed in the corresponding mounting grooves 313 on the column 303. The above settings ensure the stable installation of each component while facilitating the flexible adjustment of the height and angle to meet different environmental monitoring requirements. The electric push rod 302 drives the column 303 to lift and lower. The design of the top shaft bracket 304 enhances the stability. The overall structure is compact, the operation is simple, and the efficiency and accuracy of environmental monitoring are improved.

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

[0048] In a preferred embodiment, the flipping mechanism includes a driving motor 501. The driving motor 501 is installed on the support plate 405 and is connected to the photovoltaic panel 503 through a rotating shaft 502. The support plate 405 is provided with a machine hole 507, and the photovoltaic panel 503 is provided with a limit hole 508. Both ends of the rotating shaft 502 are respectively inserted into the machine hole 507 and the limit hole 508 to connect the driving motor 501 and the photovoltaic panel 503. The other end of the photovoltaic panel 503 is rotatably installed in the pin slot 509 and the rotating block 506 through a pin shaft. The rotating block 506 is rotatably installed on the first mounting seat 202. The rotating block 506 is provided with a pin hole 510, and a hole is also provided on the shaft at the end of the photovoltaic panel 503. The pin 504 is inserted into the pin hole 510 and the hole on the shaft at the end of the photovoltaic panel 503 to connect the photovoltaic panel 503 and the limit block 505 together. The above settings ensure that the photovoltaic panel 503 can be smoothly flipped under the drive of the driving motor 501, and through the cooperation of the pin shaft and the pin slot 509 and the pin 504 and the pin hole 510, the limit and stability of the photovoltaic panel 503 during the flipping process are realized, improving the reliability and service life of the entire flipping mechanism.

[0049] In a preferred embodiment, the protection device includes umbrella ribs 601, a buckle 603 and a pressure plate 605. One end of the umbrella rib 601 is connected to the column 303, and the other end is installed with a protection umbrella 602. The buckle 603 is installed on the lower plane of the limit block 505. The middle of the pressure plate 605 is provided with a through hole 606 and is sleeved on the column 303 through the through hole 606. A spring 604 is installed above the pressure plate 605. The spring 604 is sleeved on the column 303 and is connected to the column 303 at one end and the pressure plate 605 at the other end. The above settings effectively improve the protection performance of the photovoltaic device in harsh environments. The protection umbrella 602 is made of memory materials such as hard rubber, which can not only effectively block the erosion of sand and wind on the photovoltaic panel, but also have a certain impact resistance to protect the photovoltaic panel from accidental collisions. The combined use of the buckle 603 and the pressure plate 605 ensures the stable fixation of the protection umbrella 602 when the device is retracted, avoiding the accidental detachment of the protection umbrella in sandy weather. The addition of the spring 604 provides an additional buffering effect, further enhancing the stability and durability of the device.

[0050] In a preferred embodiment, the device further includes a warning sticker 701, and the warning sticker 701 is installed on the outer surface of the protection umbrella 602.

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

[0052] In a preferred embodiment, the specific operation steps of Step 2 are as follows: when the electric push rod 302 rises, it drives the connected column 303 to perform lifting and sliding in the working cavity 309, and cooperates with the shaft hole 312 provided on the top shaft frame 304 to limit and stabilize the column 303. After the column 303 rises, the climate detector 308 is extended to the outside for detection. With the above arrangement, it not only ensures that the climate detector 308 can accurately and stably extend and be positioned at the required position, but also realizes the real-time monitoring of the climate environment through the precise control of the electric push rod 302, greatly improving the detection efficiency and data accuracy.

With the above arrangement, it ensures that the photovoltaic panel can be effectively protected under different wind direction conditions; at the same time, the sand and dust intensity can be monitored in real time through a sensor, and the rotation angle can be automatically adjusted to further optimize the dust-proof efficiency and ensure the power generation efficiency and the service life of the device.

[0054] The climate-sensing wind and dust-proof photovoltaic device and its working method provided by the present invention propose an innovative solution to the technical problems faced by photovoltaic devices when working in harsh environments such as sand and dust, including poor dust-proof performance, low cleaning efficiency, and lack of environmental change sensing ability. Specifically, the present invention solves the problem that the cleaning efficiency of self-cleaning photovoltaic devices in harsh environments decreases significantly in the prior art, and the problem that traditional dust-proof devices require manual intervention and have high operation and maintenance costs. At the same time, the present invention also overcomes the defect that existing devices lack the ability of automatic sensing and adapting to environmental changes.

[0055] The device of the present invention integrates various functions such as climate sensing, automatic deployment and contraction, wind and dust prevention, etc., achieving all-round protection for photovoltaic equipment in harsh environments. The device adopts a unique placement method of triangular leaf-shaped photovoltaic panels 503, combined with a triangular support structure, which not only improves the space utilization rate and stability of the equipment, but also effectively guides the flow direction of wind and sand, reducing the direct impact of wind and sand on the equipment. In the protection device, memory materials such as hard rubber are innovatively used as protection umbrellas, which can not only effectively block wind and sand, but also have a certain impact resistance, providing more comprehensive and effective protection for photovoltaic equipment.

[0056] In addition, by introducing climate sensing technology, the present invention enables photovoltaic equipment to automatically sense and respond to external environmental changes, automatically adjust the working state according to weather conditions, and improve the intelligence and automation level of the equipment. This innovative design not only improves the use efficiency and service life of photovoltaic equipment in harsh environments, but also provides new ideas and methods for the development of the photovoltaic industry, with significant innovation value and application prospects.

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