Description

Technical Field

[0001] This invention belongs to the field of photovoltaic curtain wall technology, specifically, it relates to a sliding, turning dual-axis tracking photovoltaic curtain wall and its usage method. Background Technology

[0002] With the development of science and technology, people have higher and higher requirements for their living environment. In response to the demand for environmental protection and energy conservation, building technology has also been improved and innovated. For example, photovoltaic curtain walls are installed on buildings. A photovoltaic curtain wall is an auxiliary device used to absorb solar energy and convert it into electrical energy when installed on the exterior of a building. The photovoltaic curtain wall can effectively utilize the building's external structure, without the need for additional land, and can also alleviate electricity demand. It has been widely used in the field of photovoltaic conversion.

[0003] Currently, the installation method for photovoltaic curtain walls usually involves fixing the keel around the perimeter of the photovoltaic curtain wall directly to the exterior facade of the building, and then installing the photovoltaic panels on the keel to assemble the photovoltaic curtain wall. At this time, the weight of the photovoltaic curtain wall is supported by the keel. However, because the inside of the photovoltaic curtain wall is attached to the wall, the photovoltaic curtain wall cannot receive sunlight as well, thus reducing the power generation.

[0004] Chinese utility model patent application number 202423068963.3 discloses a photovoltaic panel posture adjustment device and a photovoltaic curtain wall system. The photovoltaic panel posture adjustment device includes a photovoltaic bracket and a photovoltaic panel. The photovoltaic bracket includes a support frame, a telescopic mechanism, a rotating component, and a driving mechanism. The first end of the support frame is hinged to a first predetermined position on the facade structure, with the hinge rotation axis parallel to the horizontal plane. The direction from the first end to the second end of the support frame is along the n-direction. One end of the telescopic mechanism is hinged to the second end of the support frame, and the other end is hinged to a second predetermined position on the facade structure, the second predetermined position being located below the first predetermined position. The rotating component is rotatably mounted on the support frame, with its rotation axis along the n-direction. The driving mechanism is mounted on the support frame and used to drive the rotating component to rotate. The back of the photovoltaic panel is connected and fixed to the rotating component, and the photovoltaic panel rotates as the rotating component rotates.

[0005] The aforementioned existing photovoltaic curtain walls can adjust the vertical and horizontal angles of the photovoltaic panels to ensure they receive sufficient sunlight and improve power generation efficiency. However, the position of the photovoltaic panels on the building facade is fixed, preventing them from moving relative to the facade. The power generation efficiency of a photovoltaic curtain wall primarily depends on the absorption and conversion of solar radiation energy by the photovoltaic panels, which requires sufficient and stable sunlight. The sun's trajectory throughout the day follows a natural pattern of rising in the east and setting in the west, causing the incident angle, intensity, and range of sunlight to change dynamically over time. Consequently, different facades of a building receive significantly different amounts of sunlight at different times.

[0006] Specifically, at different times of the day, the sun can only selectively illuminate one or a few facades of a building: when the sun rises in the morning, it mainly illuminates the east-facing facade; when the sun is at its zenith at noon, it mainly illuminates the south-facing facade (in the Northern Hemisphere); and when the sun sets in the evening, it mainly illuminates the west-facing facade. During this process, facades not directly illuminated by the sun (such as the west-facing and north-facing facades in the morning, the east-facing, west-facing, and north-facing facades at noon, and the east-facing and north-facing facades in the evening) can only receive a small amount of diffused light, with a light intensity far lower than that of the directly illuminated facades, and at some times, almost no effective light at all.

[0007] Because existing photovoltaic (PV) curtain walls typically have PV panels fixedly installed on the exterior facades of buildings, they cannot adjust their orientation to follow the sun's trajectory to track sunlight. This results in a significant decrease in the photoelectric conversion efficiency of PV panels on building facades with low sunlight intensity, leading to a substantial reduction in power generation. In severe cases, they may even cease operation due to insufficient sunlight, failing to generate electricity effectively. This uneven sunlight distribution across building facades caused by the sun's rising in the east and setting in the west severely restricts the overall power generation efficiency of PV curtain walls, preventing them from fully realizing the power generation potential of PV panels and reducing the energy utilization efficiency and economic viability of PV curtain walls. This has become a critical technical challenge that urgently needs to be addressed in the current application of PV curtain walls. Summary of the Invention

[0008] This invention provides a sliding, turnable, dual-axis tracking photovoltaic curtain wall and its usage method. Addressing the technical pain points in existing photovoltaic curtain wall applications, the core technical problem this invention aims to solve is: overcoming the uneven illumination of building facades caused by the natural sun's east-west movement; resolving the issue that existing photovoltaic curtain wall modules, due to their fixed installation, cannot adjust their orientation to follow the sun's trajectory and thus cannot track sunlight, resulting in low power generation or even non-functionality of photovoltaic modules on building facades with low sunlight intensity. Ultimately, this restricts the overall power generation efficiency of the photovoltaic curtain wall, fails to fully utilize the power generation potential of photovoltaic modules, and reduces the energy utilization efficiency and economy of the photovoltaic curtain wall.

[0009] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A sliding and turning dual-axis tracking photovoltaic curtain wall includes a lower sliding rail and an upper sliding rail arranged vertically. The lower sliding rail and the upper sliding rail are arranged along the shape of the building structure facade. At least one set of tracking photovoltaic brackets is movably installed between the lower sliding rail and the upper sliding rail. The tracking photovoltaic (PV) support includes a main shaft. A drive support device is connected to the lower end of the main shaft and is slidably mounted on a lower slide rail. A rotating support device is rotatably mounted on the upper end of the main shaft and is slidably mounted on an upper slide rail. The drive support device slides on the lower slide rail, and the rotating support device slides on the upper slide rail, driving the main shaft to move laterally, thus adjusting the position of the tracking PV support to the facade of the building where sunlight is strongest. The drive support device also drives the main shaft to rotate circumferentially, adjusting the circumferential position of the main shaft. At least one swing arm assembly is rotatably mounted on the main shaft along its height direction. A photovoltaic panel is mounted on the mounting end of the swing arm assembly. A pitch drive device is mounted on the main shaft. The drive end of the pitch drive device is connected to the swing arm assembly and is used to drive the swing arm assembly to swing on the main shaft so that the pitch angle of the working surface of the photovoltaic panel can adapt to the incident angle of sunlight at different times.

[0010] The following are further optimizations of the above technical solution by the present invention: The upper and lower slide rails have the same overall structure, both including a slide rail body. The slide rail body is arranged along the shape of the building structure's exterior facade. A rounded section is provided on the slide rail body at a position corresponding to the positive or negative corner of the building structure. Multiple mounting parts are fixedly installed on the slide rail body, and the mounting parts are fixedly installed on the building structure.

[0011] Further optimization: The drive support device includes a drive support part, a corner drive component, a support wheel assembly, and a lower sliding assembly. The drive support part includes a drive support bracket, a drive component connector, and a lower hinge connection part. Lower hinge connection parts are installed at both ends of the drive support bracket. When multiple brackets are connected, they are connected through the lower hinge connection parts. A lower sliding assembly is rotatably connected to each lower hinge connection part. The lower sliding assembly is slidably connected to the lower slide rail. A support wheel assembly is fixedly installed at the lower position of the drive support bracket. A corner drive component is installed on the drive support bracket. The drive end of the corner drive component is connected to the lower end of the main shaft.

[0012] Further optimization: The rotary support device includes a sliding support part and an upper sliding assembly. The sliding support part includes a rotary support bracket, a bearing, and an upper hinge connection part. The upper hinge connection parts are respectively installed at both ends of the rotary support bracket. When multiple brackets are connected, they are connected through the upper hinge connection parts. The upper sliding assembly is rotatably installed on each upper hinge connection part, and the upper sliding assembly is slidably installed on the upper slide rail. The bearing is installed on the rotary support bracket, and the upper end of the main shaft is connected to the bearing to support the rotation of the main shaft.

[0013] Further optimization: The specific positions of the corner drive component on the drive support device and the bearing on the rotary support device are swapped vertically.

[0014] Further optimization: The overall structure of the lower sliding component and the upper sliding component is the same, and the lower sliding component and the upper sliding component are sleeved on the corresponding lower sliding rail or upper sliding rail; both the lower sliding component and the upper sliding component include a sliding housing, and at least one mounting groove is opened on the inner side of the sliding housing, in which a pulley is rotatably installed; a rotating shaft is installed on the outer side of the sliding housing.

[0015] Further optimization: The swing arm assembly includes two spaced-apart swing arm components. The two swing arm components are hinged to the main shaft on their sides that are close to each other. One end of each swing arm component is fixedly connected to a support tube. The upper and lower ends of the two support tubes are respectively fixedly connected to the same purlin. The two support tubes and the two purlins form the mounting end for installing photovoltaic panels. The ends of the two swing arm components away from the support tubes are connected to the swing arm rear shaft.

[0016] Further optimization: Multiple sets of support shafts are installed on the main shaft along its height direction; Each of the two swing arms has a rotating shaft mounted on one side that is close to the other, and the rotating shaft is rotatably connected to the corresponding support rotating shaft on the main shaft.

[0017] Further optimization: The pitch drive device includes a pitch drive component, a swing arm linkage, and a push rod seat. The swing arm linkage is connected to the rear axle of the swing arm assembly, and the swing arm linkage drives the swing arm assembly to move.

[0018] The present invention also provides a method for using a sliding and turning dual-axis tracking photovoltaic curtain wall. Based on the above-mentioned sliding and turning dual-axis tracking photovoltaic curtain wall, the method includes: S1, adjusting the position of the photovoltaic power generation, S2, adjusting the circumferential angle of attack, and S3, adjusting the pitch angle of attack. Among them, the operation steps of S1, adjusting the position of photovoltaic power generation are as follows: First, based on the changes in sunlight from sunrise to sunset throughout the day, determine the facade of the building that receives the strongest sunlight at different times; then drive the tracking photovoltaic bracket to move laterally on the lower and upper sliding rails, move the tracking photovoltaic bracket to the sunlight-receiving facade of the building, so that the photovoltaic panels on the tracking photovoltaic bracket always correspond to the direction of sunlight, thereby improving the power generation efficiency of the photovoltaic panels; S2. The operation steps of the circumferential angle adjustment process are as follows: Based on the azimuth of the sun rising in the east and setting in the west throughout the day, determine the incident angle of sunlight at different times and the required orientation of the photovoltaic panel's light-receiving surface; start the corner drive to drive the main shaft to rotate circumferentially; the rotation of the main shaft synchronously drives the photovoltaic panel to adjust its circumferential position so that the light-receiving surface of the photovoltaic panel is precisely aligned with the sunlight at the corresponding time. S3. The operation steps of the tilt angle adjustment process are as follows: Based on the changes in the solar altitude angle throughout the day, determine the optimal tilt angle required by the photovoltaic panel at the corresponding time; start the tilt drive device; the swing arm linkage drives the swing arm assembly to swing synchronously along the hinge with the main shaft; adjust the tilt angle of the photovoltaic panel until the photovoltaic panel is adjusted to the optimal tilt angle suitable for the solar altitude angle at the corresponding time.

[0019] The present invention, by adopting the above technical solution, has at least the following beneficial effects: 1. This invention combines the process of adjusting the position of the photovoltaic power generation, the process of adjusting the circumferential angle of sunlight, and the process of adjusting the pitch angle of sunlight, thereby realizing the all-round and precise adjustment of the photovoltaic panel's sunlight exposure. This effectively solves the technical pain points of existing photovoltaic curtain wall photovoltaic panels, such as limited light-receiving range, inability to adapt to changes in sunlight at different times and seasons, resulting in low power generation, unstable working efficiency, or even failure to work.

[0020] 2. Achieving precise dual adjustment of photovoltaic panel position and angle, significantly improving power generation efficiency: The photovoltaic power generation position adjustment process drives the tracking photovoltaic bracket to move laterally along the lower and upper sliding rails, enabling the photovoltaic panel to precisely switch to the facade with the strongest sunlight, avoiding insufficient sunlight due to building facade obstruction or light offset; the circumferential sunlight angle adjustment process and the pitch sunlight angle adjustment process work together to adapt to the changes in azimuth and altitude angles of the sun throughout the day, ensuring that the working surface of the photovoltaic panel is always precisely aligned with the sunlight, maximizing the light intensity and duration of the photovoltaic panel, and significantly increasing photovoltaic power generation. Compared with existing photovoltaic panels with fixed positions, the power generation efficiency improvement is significant.

[0021] 3. Standardized operation process and high degree of automation, reducing usage and maintenance costs: All three processes follow the standardized process of "sunlight judgment - drive adjustment - precise alignment". The operation logic is clear and highly executable, requiring no manual intervention. Through the coordinated drive of components such as corner drive and tilt drive, the circumferential, tilt angle and installation position of the photovoltaic panel are automatically adjusted, avoiding errors caused by manual adjustment and ensuring adjustment accuracy and power generation stability.

[0022] 4. High adaptability and wide range of applications: This invention can flexibly adapt to different building facade structures. The photovoltaic panels can be switched on different building facades by moving along the sliding rails. The dual-axis angle adjustment can adapt to changes in sunlight at different latitudes, seasons, and times of day. It can automatically adjust according to the building structure or regional sunlight characteristics, adapting to various photovoltaic curtain wall application scenarios and is extremely practical.

[0023] 5. Strong structural linkage ensures equipment stability: Multiple swing arm components swing synchronously through the swing arm linkage, ensuring that the pitch angle adjustment of all photovoltaic panels is consistent, avoiding overall power generation imbalance caused by adjustment deviation of a single photovoltaic panel; the transmission coordination of each drive component is precise, the adjustment process is smooth, reducing equipment wear, extending the service life of the photovoltaic curtain wall and its components, and ensuring long-term stable operation of the photovoltaic panels, avoiding power generation interruption caused by adjustment mechanism failure.

[0024] 6. Coherent technical logic, solving the core pain points of existing technologies: This invention specifically addresses the core defects of existing photovoltaic panels, namely, "fixed position and fixed angle that cannot be adjusted". It organically combines position adjustment with dual-axis angle adjustment to form a comprehensive tracking and sunlight-facing system. This solves both the problem of insufficient light reception caused by light azimuth deviation and the problem of low power generation efficiency caused by incident angle deviation. At the same time, it enhances the stability of photovoltaic panel operation in different seasons. The technology has outstanding advantages and has extremely high practicality and promotion value.

[0025] 7. The photovoltaic tracking bracket in the photovoltaic curtain wall of this invention can make large-angle turns, so the photovoltaic curtain wall can be retracted when not in use or during inclement weather to avoid damage and improve the overall service life. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] like Figure 1-16As shown: A sliding and turning dual-axis tracking photovoltaic curtain wall includes a lower sliding rail 1 and an upper sliding rail 2 symmetrically arranged vertically. The lower sliding rail 1 and the upper sliding rail 2 are arranged along the shape of the building structure facade, and each corner is a smooth arc. At least one set of tracking photovoltaic brackets is movably installed between the lower sliding rail 1 and the upper sliding rail 2. At least one photovoltaic panel 8 is installed on the tracking photovoltaic bracket along its height direction. The tracking photovoltaic bracket can adjust its specific position by moving laterally on the lower sliding rail 1 and the upper sliding rail 2 according to the intensity and range of sunlight. The tracking photovoltaic bracket can also automatically adjust the circumferential angle and pitch angle of each photovoltaic panel 8 according to the incident angle of sunlight.

[0030] In this embodiment, it should be explained that: the building structure has various forms, which are suitable for the installation of photovoltaic curtain walls. The forms of building structures include masonry building structures, metal frame structures, facade walls, irregular-shaped buildings, and skeleton structures with upper and lower beams, etc.

[0031] The tracking photovoltaic bracket includes a main shaft 3. A drive support device 4 is connected to the lower end of the main shaft 3. The drive support device 4 is slidably mounted on the lower slide rail 1. A rotating support device 5 is rotatably mounted on the upper end of the main shaft 3. The rotating support device 5 is slidably mounted on the upper slide rail 2. The drive support device 4 slides on the lower slide rail 1, and the rotating support device 5 slides on the upper slide rail 2, which is used to drive the main shaft 3 to move laterally, thereby adjusting the position of the tracking photovoltaic bracket to the facade of the building with the strongest sunlight. The drive support device 4 can drive the main shaft 3 to rotate circumferentially, which is used to adjust the circumferential position of the main shaft 3. The rotating support device 5 is used to support the rotation of the main shaft 3.

[0032] At least one swing arm assembly 6 is rotatably mounted on the main shaft 3 along its height direction. The mounting end of the swing arm assembly 6 is located in front of the main shaft 3 and is used to mount the photovoltaic panel 8. A pitch drive device 7 is mounted on the main shaft 3. The drive end of the pitch drive device 7 is connected to the side of the swing arm assembly 6 away from the photovoltaic panel 8. When the pitch drive device 7 is activated, it drives the swing arm assembly 6 to swing on the main shaft 3, thereby adjusting the pitch angle of the photovoltaic panel 8. This allows the circumferential and pitch angles of the working surface of the photovoltaic panel 8 to adapt to the angle of sunlight incidence at different times, thereby improving the photovoltaic power generation.

[0033] In this embodiment, multiple swing arm assemblies 6 are installed on each main shaft 3. The multiple swing arm assemblies 6 are arranged at intervals, and at least one photovoltaic panel 8 is installed on each swing arm assembly 6. The swing arm assembly 6 swings on the main shaft 3 to drive the photovoltaic panel 8 to swing.

[0034] In this embodiment, the lower slide rail 1 and the upper slide rail 2 are arranged symmetrically and at intervals. The lower slide rail 1 and the upper slide rail 2 are fixedly installed on the exterior of the building structure. The lower slide rail 1 and the upper slide rail 2 serve as the main structure of the photovoltaic curtain wall and are used to support the installation of the tracking photovoltaic bracket, thereby constructing a stable support platform.

[0035] The upper and lower slide rails 1 and 2 have the same overall structure, both including a slide rail body 101. The slide rail body 101 is arranged along the shape of the building structure's exterior facade. When it encounters a positive or negative corner of the building structure, the slide rail body 101 is provided with an arc transition section 103 that matches the shape of the corresponding corner. The arc transition section 103 is a smooth arc shape.

[0036] Multiple mounting parts 102 are fixedly installed on the slide rail body 101 along its direction. The multiple mounting parts 102 are arranged at intervals. The mounting parts 102 are fixedly installed on the exterior of the building structure by pre-embedding, welding or bolt fastening.

[0037] In this embodiment, the mounting part 102 on the lower slide rail 1 is fixedly installed on the bottom surface by pre-embedding, and the mounting part 102 on the upper slide rail 2 is fixedly installed at the upper end of the exterior facade of the building structure by pre-embedding. The lower slide rail 1 and the upper slide rail 2 are arranged vertically. The fixed installation of the lower slide rail 1 and the upper slide rail 2 is used to build a stable support and installation platform for the photovoltaic curtain wall on the exterior facade of the building structure.

[0038] The drive support device 4 includes a drive support part 401, a corner drive component 402, a support wheel assembly 403, and a lower sliding assembly 404. The drive support part 401 includes a drive support bracket 4011, a drive component connector 4012, and a lower hinge connection part 4013. The lower hinge connection part 4013 is installed at both ends of the drive support bracket 4011.

The corner drive component 402 is installed on the drive support bracket 4011. The drive end of the corner drive component 402 is connected to the lower end of the main shaft 3.

[0039] With this design, the support wheel assembly 403 can be placed on the ground or in the guide rail. The rotation of the support wheel assembly 403 drives the drive support bracket 4011 to slide on the lower slide rail 1, thereby adjusting the position of the drive support bracket 4011 on the lower slide rail 1. The two ends of the drive support bracket 4011 are slidably connected to the lower slide rail 1 through the lower sliding assembly 404, which facilitates assembly and installation and supports the drive support bracket 4011 to move on the lower slide rail 1, improving the use effect and the convenience of position adjustment operation. The corner drive component 402 works to drive the main shaft 3 to rotate circumferentially. At this time, the main shaft 3 drives the swing arm assembly 6 and the photovoltaic panel 8 to rotate circumferentially, which is used to adjust the circumferential position of the photovoltaic panel 8.

[0040] In this embodiment, the support wheel assembly 403 includes a support wheel, which is rotatably mounted on the upright. The upright is fixedly mounted below the drive support bracket 4011, and the support wheel assembly 403 is placed on the bottom surface. The support wheel of the support wheel assembly 403 rolls on the bottom surface to support the drive support bracket 4011 to move on the lower rail 1.

[0041] In this embodiment, when the support wheel assembly 403 uses a support wheel, the drive of the drive support bracket 4011 can be achieved by an external traction device. The external traction device works to pull the drive support bracket 4011 to move on the lower rail 1. In conjunction with the control program that measures and calculates the lighting conditions of the building's exterior, the position of the drive support bracket 4011 on the lower rail 1 can be automatically adjusted without manual intervention.

[0042] In addition to this embodiment, the support wheel assembly 403 can also be a self-driving drive wheel. The drive wheel is installed in the lower middle part of the drive support bracket 4011 and is installed in the guide rail. The guide rail is laid out along the direction of the lower slide rail 1. The drive wheel starts to move under the limit of the guide rail. With the help of the control program that measures and calculates the lighting conditions of the building shape, the position of the drive support bracket 4011 on the lower slide rail 1 can be automatically adjusted without manual intervention.

[0043] In this embodiment, the external traction device and the self-driving drive wheel are both existing technologies and can be purchased directly from the market. Their main function is to output power and transmit it to the drive support bracket 4011, so that the drive support bracket 4011 can move automatically on the lower rail 1. The specific structure is not described in detail here.

A drive component connector 4012 is fixedly installed at the upper middle position of the drive support bracket 4011. The reducer is fixedly installed on the drive component connector 4012. The drive end of the reducer is vertically arranged upward and is connected to the lower end of the main shaft 3. The drive motor is fixedly installed on the reducer.

[0045] With this design, the angle drive 402 starts and outputs rotational power to drive the spindle 3 to rotate, and the angle drive 402 can also be used to control the specific rotation direction, rotation angle and response time of the spindle 3.

[0046] In this embodiment, the two ends of the drive support bracket 4011 are respectively fixedly installed with lower hinge connection parts 4013, and the lower sliding components 404 are respectively rotatably installed on the lower hinge connection parts 4013, which facilitates assembly and installation.

[0047] In addition to this embodiment, the corner drive 402 can also be adopted Figure 17 As shown: The corner drive component 402 includes a corner push rod 405, which is mounted on a drive support bracket 4011. A bearing seat is fixedly mounted on the drive component connector 4012 of the drive support bracket 4011. The lower end of the main shaft 3 is rotatably connected to the bearing seat. A corner push rod seat 304 is hinged to the telescopic end of the corner push rod 405. The other end of the corner push rod seat 304 is fixedly connected to the main shaft 3.

[0048] A push rod support 4014 is fixedly installed on the drive support bracket 4011 at a position corresponding to the corner push rod 405. The corner push rod 405 is installed on the push rod support 4014, thereby realizing the installation of the corner push rod 405 on the drive support bracket 4011, which facilitates assembly and installation.

[0049] With this design, the corner push rod 405 drives the corner push rod seat 304 to swing, and the swing of the corner push rod seat 304 drives the main shaft 3 to rotate, thereby driving the main shaft 3 to rotate, which is used to adjust the circumferential angle of the photovoltaic panel 8.

[0050] In addition to this embodiment, a gear disk structure can also be used as the driving part in the drive support device 4.

[0051] In this embodiment, the overall structure of the drive support bracket 4011 is V-shaped, and the two sliding components 404 on the drive support bracket 4011 are slidably connected to the lower rail 1. The support wheel assembly 403 is in contact with the ground. At this time, the two sliding components 404 and the support wheel assembly 403 can form a triangular support point to achieve stable support for the drive support bracket 4011, thereby tracking the overall stability of the photovoltaic bracket.

[0052] In addition to this embodiment, the overall structure of the drive support bracket 4011 can also adopt a T-shaped frame, a triangular frame, a square frame, or other structural forms.

[0053] The rotating support device 5 includes a sliding support part 501 and an upper sliding assembly 502. The sliding support part 501 includes a rotating support bracket 5011, a bearing 5012, and an upper hinge connection part 5013. The upper hinge connection part 5013 is installed at both ends of the rotating support bracket 5011. When multiple brackets are connected, they are connected through the upper hinge connection part 5013. The upper sliding assembly 502 is rotatably installed on each upper hinge connection part 5013, and the upper sliding assembly 502 is slidably installed on the upper slide rail 2.

[0055] In this embodiment, the overall structure of the rotating support bracket 5011 is V-shaped. At this time, the two upper sliding components 502 and the bearing 5012 can form a triangular support point to achieve stable support for the upper end of the main shaft 3.

[0056] In addition to this embodiment, the overall structure of the rotating support bracket 5011 can also adopt a T-shaped frame, a triangular frame, a square frame, or other structural forms.

The main shaft 3 is slidably mounted between the lower sliding component 1 and the upper sliding component 502 through the cooperation of the lower sliding component 404 and the upper sliding component 502. This allows the main shaft 3 to slide on the lower sliding component 1 and the upper sliding component 2, adjusting the lateral position of the main shaft 3. This enables it to adapt to the rising and setting of the sun, allowing the main shaft 3 to move the photovoltaic panel 8 on it to the side of the building facade with sufficient sunlight, thereby significantly improving the photoelectric conversion efficiency and increasing the power generation.

[0058] In this embodiment, the specific positions of the corner drive 402 on the drive support device 4 and the bearing 5012 on the rotary support device 5 can be interchanged; that is, the corner drive 402 is fixedly installed on the rotary support bracket 5011 of the rotary support device 5, and the power output end of the corner drive 402 is connected to the upper end of the main shaft 3; the bearing 5012 is installed on the lower end of the main shaft 3, and the bearing 5012 is fixedly installed on the drive support bracket 4011 of the drive support device 4.

[0062] In this embodiment, the pivot 4043 of the lower sliding component 404 is rotatably connected to the lower hinge connection 4013, so that the lower sliding component 404 is rotatably mounted on the drive support bracket 4011. The pivot 4043 of the upper sliding component 502 is rotatably connected to the upper hinge connection 5013, so that the upper sliding component 502 is rotatably mounted on the rotating support bracket 5011, which facilitates assembly and installation.

[0063] In this embodiment, taking the installation of the lower sliding component 404 as an example, the following description is provided: the rotating shaft 4043 of the lower sliding component 404 is rotatably connected to the lower hinge connection part 4013, so that the lower sliding component 404 is rotatably installed on the drive support bracket 4011. The sliding housing 4042 is sleeved on the lower sliding rail 1, and the pulley 4041 is slidably connected to the lower sliding rail 1, so that the sliding housing 4042 is slidably installed on the lower sliding rail 1, which facilitates assembly and installation, and thus enables the drive support bracket 4011 to be slidably installed on the lower sliding rail 1.

[0064] In this embodiment, the inner side of the sliding housing 4042 is provided with three mounting slots, which are arranged in a ring and spaced apart from each other. Each of the three mounting slots is equipped with a pulley 4041. The three pulleys 4041 simultaneously contact the corresponding lower slide rail 1 or upper slide rail 2, so as to realize the stable sliding installation of the sliding housing 4042 on the corresponding lower slide rail 1 or upper slide rail 2, which facilitates assembly and installation.

[0065] In addition to this embodiment, the inner side of the sliding housing 4042 may have other numbers of mounting slots, such as one, two, four, etc.

[0066] In this embodiment, an opening is provided on the outer side wall of the sliding housing 4042 corresponding to the rotating shaft 4043. The sliding housing 4042 can be easily installed on the corresponding lower slide rail 1 or upper slide rail 2 through the opening, which facilitates assembly and installation.

[0067] The overall structure of the main shaft 3 includes a main shaft body 301. Multiple sets of support shaft groups are installed at equal intervals along the height direction of the main shaft body 301. Each set of support shaft groups is used to rotatably support and install a set of swing arm assemblies 6. Each set of support shaft groups includes two symmetrically arranged support shafts 302. The two support shafts 302 are respectively fixedly installed on both sides of the main shaft 3.

[0068] The swing arm assembly 6 includes two spaced-apart swing arm components 603. One end of each swing arm component 603 is fixedly connected to a support tube 602. The upper and lower ends of the two support tubes 602 are respectively fixedly connected to the same purlin 601. The two support tubes 602 and the two purlins 601 form the mounting end for installing the photovoltaic panel 8.

[0069] The ends of the two swing arm components 603 away from the support tube 602 are connected to the same swing arm rear shaft 605, which is used to connect the two swing arm components 603 into one unit.

[0070] A rotating shaft 604 is fixedly installed at the middle of the side of the two swing arm components 603 that are close to each other. The rotating shaft 604 is rotatably connected to the corresponding support rotating shaft 302 on the main shaft 3.

[0071] This design allows the swing arm assembly 6 to be hingedly mounted on the main shaft 3 via the rotational connection between the rotating shaft 604 and the corresponding support rotating shaft 302 on the main shaft 3. When the swing arm assembly 6 swings along the connection between the rotating shaft 604 and the support rotating shaft 302, it is used to adjust the pitch angle of the photovoltaic panel 8, making it convenient to use.

[0072] The pitch drive device 7 includes a pitch drive component 701, a swing arm connecting rod 702, and a push rod seat 703. The pitch drive component 701 is hinged and installed at the upper position of the main shaft 3. The pitch drive component 701 is arranged at an angle. The telescopic end of the pitch drive component 701 is hinged to the upper end of the swing arm connecting rod 702. When the pitch drive component 701 is activated, its telescopic end extends or retracts. At this time, the pitch drive component 701 is used to drive the swing arm connecting rod 702 to move vertically downward or downward, which is convenient to use.

[0073] The swing arm connecting rod 702 is arranged parallel to or at a certain angle to the main shaft 3, and the swing arm connecting rod 702 is connected to the swing arm rear shaft 605 of the swing arm assembly 6.

[0074] This design enables multiple swing arm assemblies 6 on the same main shaft 3 to swing synchronously via the swing arm linkage 702. Specifically, when a vertical upward or downward moving force is applied to the swing arm linkage 702, the swing arm linkage 702 moves upward or downward. At this time, the swing arm linkage 702 drives multiple swing arm assemblies 6 on the main shaft 3 to swing synchronously, so that multiple swing arm assemblies 6 can drive the corresponding photovoltaic panels 8 to swing, thereby adjusting the pitch angle of the photovoltaic panels 8.

[0075] In this embodiment, an elevation push rod seat 303 is fixedly installed on the main shaft 3 near its upper end. The mounting end of the pitch drive 701 is hinged to the elevation push rod seat 303. The upper end of the swing arm connecting rod 702 is also fixedly connected to the push rod seat 703. The telescopic end of the pitch drive 701 is hinged to the push rod seat 703.

[0076] The pitch drive 701 adopts an electric telescopic rod, a hydraulic cylinder, or a telescopic cylinder. In this embodiment, the pitch drive 701 preferably adopts an electric telescopic rod, which eliminates the need for a high-pressure air source and hydraulic station, and also eliminates the need for complex hydraulic and pneumatic pipelines, thus simplifying the overall structure.

[0077] In addition to this embodiment, the pitch drive device 7 can also employ... Figure 18 As shown, the pitch drive device 7 includes a pitch reducer 704. The pitch reducer 704 is fixedly mounted on the main shaft 3 using a support frame. The power output end of the pitch reducer 704 is connected to the swing arm assembly 6. The pitch reducer 704 outputs rotational power to drive the corresponding swing arm assembly 6 to swing. At this time, with the cooperation of the swing arm connecting rod 702, all the swing arm assemblies 6 can be driven to swing synchronously, which is convenient to use.

[0078] A reducer support 705 is fixedly installed on the main body 301 of the main spindle 3 at a position corresponding to the elevation reducer 704. The elevation reducer 704 is fixedly installed on the reducer support 705. The reducer support 705 is used to fix the elevation reducer 704 on the main body 301, which facilitates assembly and installation.

[0079] A gear-disc structure can also be used as the driving form for the pitch drive device 7.

[0080] In addition to this embodiment, multiple sets of tracking photovoltaic brackets can be installed on the lower slide rail 1 and the upper slide rail 2. Each set of tracking photovoltaic brackets has a photovoltaic panel 8 installed on its swing arm assembly 6. The lower hinge connection parts 4013 of the two drive support brackets 4011 of two adjacent tracking photovoltaic brackets are hinged to each other at one end and share a set of lower sliding components 404. The upper hinge connection parts 5013 of the two rotating support brackets 5011 are hinged to each other at one end and share a set of upper sliding components 502. This enables the two adjacent tracking photovoltaic brackets to be connected into one unit and move synchronously.

[0081] The present invention also provides a method for using a sliding and turning dual-axis tracking photovoltaic curtain wall. Based on the above-mentioned sliding and turning dual-axis tracking photovoltaic curtain wall, it includes: S1, adjusting the position of photovoltaic power generation: First, according to the intensity and range of sunlight, the tracking photovoltaic support is moved laterally on the lower slide rail 1 and the upper slide rail 2 to adjust the specific position of the photovoltaic panel 8 on the exterior facade of the building. S2, Circumferential Sunlight Angle Adjustment Process: The main shaft 3 rotates to adjust the circumferential sunlight angle of the photovoltaic panel 8; S3, Pitch-to-light angle adjustment process: The pitch drive device 7 on the main shaft 3 is activated to drive the swing arm assembly 6 to swing on the main shaft 3, thereby adjusting the pitch angle of the photovoltaic panel 8.

[0082] In this embodiment, the circumferential and pitch angles of the working surface of the photovoltaic panel 8 can be automatically adjusted through the S2 circumferential angle adjustment process and the S3 pitch angle adjustment process, thereby adapting to the incident angle of sunlight at different times and improving photovoltaic power generation.

[0083] Among them, the specific operation steps of S1, adjusting the position of photovoltaic power generation, are as follows: First, based on the changes in sunlight from sunrise to sunset throughout the day, determine the facade of the building that receives the strongest sunlight at different times; then drive the tracking photovoltaic bracket to move laterally on the lower slide rail 1 and the upper slide rail 2, move the tracking photovoltaic bracket to the sunlight-receiving facade of the building, so that the photovoltaic panel 8 on the tracking photovoltaic bracket always corresponds to the direction of sunlight, so as to improve the power generation efficiency of the photovoltaic panel 8 and avoid the photovoltaic panel 8 from having low power generation or not working due to low sunlight.

[0084] S2. The specific operation steps of the circumferential angle adjustment process are as follows: Based on the azimuth of the sun rising in the east and setting in the west throughout the day, determine the incident angle of sunlight at different times and the required orientation of the light-receiving surface of the photovoltaic panel 8; start the corner drive 402 to drive the main shaft 3 to rotate circumferentially around its own axis; through the circumferential rotation of the main shaft 3, drive the multiple photovoltaic panels 8 installed along its height direction to adjust their circumferential positions synchronously until the light-receiving surface of the photovoltaic panel 8 is accurately aligned with the sunlight at the corresponding time, so as to avoid the photovoltaic panel 8 from having low power generation or not working because the light-receiving surface cannot correspond to the incident angle of sunlight, thereby improving the power generation efficiency of the photovoltaic panel 8.

[0085] S3. The specific operation steps of the pitch angle adjustment process are as follows: Based on the changes in the solar altitude angle throughout the day, determine the optimal pitch angle required for the photovoltaic panel 8 at the corresponding moment; activate the pitch drive 701 to drive the swing arm linkage 702 to move up and down; utilize the synchronous connection between the swing arm linkage 702 and multiple swing arm components 6 to drive multiple swing arm components 6 to swing synchronously along the hinge point with the main shaft 3; through the swing of the swing arm components 6, synchronously adjust the pitch angle of the photovoltaic panel 8 on each swing arm component 6 until the photovoltaic panel 8 is adjusted to the optimal pitch angle suitable for the solar altitude angle at the corresponding moment, ensuring the power generation efficiency and working stability of the photovoltaic panel 8.
