Description

Technical Field

[0001] This invention relates to the field of photovoltaic energy-saving curtain wall technology, specifically a photovoltaic energy-saving curtain wall based on a renewable energy system. Background Technology

[0002] As a key interface for energy exchange between buildings and the outside world, the energy efficiency of building exterior walls has attracted much attention. With the dual attributes of building envelope and photovoltaic power generation, photovoltaic curtain walls can efficiently integrate building space and renewable energy resources, converting clean and renewable solar energy into electricity for building use. This reduces the building's dependence on traditional fossil fuels and reduces losses during energy transmission, making it an important carrier for achieving building energy self-sufficiency and improving building energy efficiency. The demand for photovoltaic curtain walls in various new and renovated building exterior wall applications is growing.

[0003] For example, patent CN115233877B discloses a photovoltaic glass curtain wall system, including a photovoltaic curtain wall body, a first horizontal beam, and a second horizontal beam. A heat dissipation duct is formed inside the photovoltaic curtain wall body. The first horizontal beam is installed on the photovoltaic curtain wall body and has an outdoor air inlet and a first air outlet. The outdoor air inlet connects to the first air outlet, and the air inlet of the heat dissipation duct connects to the first air outlet. The second horizontal beam is installed on the photovoltaic curtain wall body and has an outdoor air outlet and a second air outlet. The outdoor air outlet connects to the second air outlet, and the air outlet of the heat dissipation duct connects to the second air outlet. Outdoor air flows sequentially through the outdoor air inlet, the first air outlet, the heat dissipation duct, the second air outlet, and the outdoor air outlet. The photovoltaic glass curtain wall can circulate and dissipate the heat generated by the photovoltaic curtain wall body, preventing heat from remaining between layers and entering the interior, thus saving energy and protecting the environment.

[0004] For example, patent CN220353714U discloses a photovoltaic curtain wall, including a photovoltaic curtain wall body and a main frame. The photovoltaic curtain wall body is fixedly installed in the main frame. The photovoltaic curtain wall also includes a fixed frame with an adjustment mechanism. The adjustment mechanism includes two support blocks symmetrically fixed to the surface of the fixed frame. The main frame is rotatably connected between the two support blocks via a rotating shaft. One end of the rotating shaft is equipped with a drive component for controlling the movement of the rotating shaft. By rotating a first rod, the first rod drives a worm gear to rotate, which in turn drives a worm wheel and the rotating shaft to rotate, thereby causing the rotating shaft to drive the main frame and the photovoltaic curtain wall body to rotate. This allows adjustment of the angle between the photovoltaic curtain wall body and the wall, enabling users to adjust the opening degree of the photovoltaic curtain wall body according to their needs when opening the window, thus ensuring the view after opening the window and improving the usage effect.

[0005] For example, patent CN222685828U discloses a photovoltaic module and a photovoltaic curtain wall, including a curtain wall frame. The surface of the curtain wall frame has a placement groove, and the inner cavity of the placement groove is slidably connected to the photovoltaic curtain wall body. The inner wall of the curtain wall frame is equipped with a cleaning mechanism. This cleaning mechanism enables the self-cleaning of the photovoltaic curtain wall body. A motor drives the rotation of a first transmission wheel, which in turn drives the rotation of a second transmission wheel and the movement of a transmission belt, thereby moving a connecting plate. The cleaning plate contacts the glass layer of the photovoltaic curtain wall body, thus cleaning the glass layer and preventing dust from obstructing the glass windows, ensuring the normal operation of the photovoltaic curtain wall body. The cleaning mechanism is achieved through a connecting rod and a screw on the inner wall of the cleaning plate. The textured connection facilitates easy replacement of the cleaning plate, reducing replacement difficulty and time. Existing photovoltaic (PV) curtain walls completely enclose the building's exterior, blocking airflow between the inside and outside of the building and failing to meet the building's natural ventilation and lighting requirements. Furthermore, the fixed orientation of the PV panels makes it difficult to adapt to dynamic changes in solar altitude and azimuth angles, limiting light conversion efficiency. Some rotating PV panels, under strong wind conditions, are prone to turbulent airflow on their surface, resulting in significant wind resistance loads that significantly affect the installation stability and structural safety of the PV curtain wall. In addition, the complex high-altitude working environment on building exteriors makes cleaning the PV panel surface difficult, and dust accumulation can lead to a decrease in photoelectric conversion efficiency, hindering the conversion and utilization of renewable energy.

[0006] To address the aforementioned issues, there is an urgent need for innovative designs based on existing photovoltaic energy-saving curtain walls. Summary of the Invention

[0007] The purpose of this invention is to provide a photovoltaic energy-saving curtain wall based on a renewable energy system, in order to solve the problems mentioned in the background art, such as the fact that some existing photovoltaic curtain walls are enclosed on the exterior walls of buildings, which is not conducive to the ventilation and lighting of buildings, and the fixed orientation of photovoltaic panels makes it difficult to adapt to the dynamic changes of solar altitude angle and azimuth angle, thus limiting the light energy conversion efficiency. In addition, the photovoltaic panels with partially rotating designs are prone to airflow turbulence on the surface of the photovoltaic panels under strong wind conditions, resulting in large wind resistance loads, which significantly affect the installation stability and structural safety of the photovoltaic curtain wall. Furthermore, the complex high-altitude working environment on the exterior walls of buildings makes it difficult to clean the surface of the photovoltaic panels, and dust accumulation can easily lead to the degradation of photoelectric conversion efficiency, which is not conducive to the conversion and utilization of renewable energy.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a photovoltaic energy-saving curtain wall based on a renewable energy system, comprising longitudinal beam assemblies installed on the exterior wall of a building, with transverse beam assemblies vertically installed on the longitudinal beam assemblies, and a positioning frame sealed between the longitudinal beam assemblies and the transverse beam assemblies. The renewable energy system within the positioning frame includes a folding photovoltaic power generation module and a clean energy guiding module. The folding photovoltaic power generation module converts renewable solar energy into electrical energy. The folding photovoltaic power generation module includes a fixed strip plate centrally fixedly installed in the positioning frame, and two sets of movable strip plates symmetrically installed in the positioning frame about the fixed strip plate. The movable strip plates are fitted and slidably installed in the positioning frame. Two sets of photovoltaic panels are arranged between the movable strip plates and the positioning frame, and the two sets of photovoltaic panels are rotatably connected to each other. The other side of each set of photovoltaic panels is rotatably connected to the movable strip plate and the fixed strip plate, respectively. A power mechanism for driving the photovoltaic panels to rotate and fold is provided on the positioning frame. The clean energy guiding module is used to clean dust on the surface of the photovoltaic panels and improve the solar energy conversion rate. The clean energy guiding module is segmented and attached to the surface of the folding photovoltaic power generation module.

[0009] Preferably, the power mechanism includes a transverse slide groove opened laterally on the positioning frame, a movable bracket slidably connected in the transverse slide groove, and the movable bracket is fixedly connected to the movable strip.

[0010] Preferably, two sets of support frames are fixedly installed on the back of the positioning frame. A threaded rod is rotatably connected to the upper support frame, and a bidirectional power motor is fixedly installed in the upper support frame. The threaded rod is connected to the output end of the bidirectional power motor. A cylindrical rod is fixedly installed in the lower support frame, and a movable bracket is slidably sleeved on the outside of the cylindrical rod. The upper part of the movable bracket is threadedly connected to the threaded rod.

[0011] Preferably, two sets of the cleaning flow guiding modules are symmetrically arranged about the horizontal central axis of the photovoltaic panel, and a cleaning transmission mechanism is provided on the positioning frame to drive the two sets of cleaning flow guiding modules to move in opposite directions on the photovoltaic panel.

[0012] Preferably, the cleaning and guiding module includes a lifting frame arranged parallel to the front of the photovoltaic panel, with rollers rotatably mounted on the lifting frame and rolling against the surface of the photovoltaic panel; two sets of lifting frames are symmetrically arranged about the longitudinal central axis of the photovoltaic panel, and a guide strip is fixedly installed between the two sets of lifting frames, with two sets of scraper strips fixedly installed on the guide strips and the scraper strips are attached to the surface of the photovoltaic panel.

[0013] Preferably, the guide strip has an embedded groove, and a guide rod is fixedly installed on the front surface of the photovoltaic panel. The guide strip is slidably engaged with the guide rod through the embedded groove.

[0014] Preferably, the side of the guide strip away from the photovoltaic panel is arc-shaped, and multiple arc-shaped guide grooves are equally spaced on the outer arc surface of the guide strip. In addition, multiple straight guide grooves that communicate with the arc-shaped guide grooves are equally spaced on the guide strip, and the straight guide grooves are longitudinally opened on the guide strip.

[0015] Preferably, the cleaning transmission mechanism includes two sets of intermediate slides symmetrically opened on the fixed plate along the transverse central axis, and an intermediate slider is slidably installed in the intermediate slide; two sets of side slides symmetrically opened on the movable plate along the transverse central axis, and side sliders are slidably installed in the side slides.

[0016] Preferably, a crossbar is fixedly installed on the middle slider, and the side sliders are slidably installed on the outside of the crossbar; a protrusion is fixedly installed on the middle slider, and a transmission support rod is rotatably connected to the protrusion, with the other end of the transmission support rod rotatably connected to the movable bracket.

[0017] Preferably, the side slider and the side slide rail surfaces are elastically connected to the lifting frame in front of the adjacent photovoltaic panel through a secondary curve spring, and the two sets of lifting frames corresponding to the joint of the two sets of adjacent photovoltaic panels are elastically connected through a main curve spring.

[0018] Compared with the prior art, the beneficial effects of the present invention are: the photovoltaic energy-saving curtain wall based on the renewable energy system can dynamically adjust the angle between photovoltaic panels according to the building's ventilation, lighting needs and the angle of sunlight by folding photovoltaic power generation modules, so as to maintain the ventilation effect of the building's exterior wall and the lighting needs of the building's interior. At the same time, it can improve the light energy conversion rate by adjusting the angle of the photovoltaic panels in winter and other seasons with weak sunlight, so as to make full use of renewable solar energy.

[0019] The positioning frame is equipped with a power mechanism that drives the photovoltaic panels to rotate and fold. By controlling the rotation of the threaded rod, the movable support moves laterally on the positioning frame under the threaded transmission. The movable support drives the movable strip to move synchronously, so that the two sets of photovoltaic panels between the movable strip and the fixed strip rotate and fold, adjusting the angle of the photovoltaic panels. At the same time, it can open up a part of the positioning frame to meet the ventilation and lighting needs of the building.

[0020] The cleaning and flow guiding module is used to clean the dust on the surface of photovoltaic panels and improve the solar energy conversion rate. The cleaning and flow guiding module is segmented and attached to the surface of the folded photovoltaic power generation module. Each folded photovoltaic panel has a cleaning and flow guiding module. Whether the photovoltaic panel is rotated, folded or fully unfolded, the cleaning and flow guiding module can be controlled to move longitudinally on the surface of the photovoltaic panel. The dust on the surface of the photovoltaic panel is cleaned by a scraper. In the rainy season, with the help of rainwater, the dust on the surface of the photovoltaic panel can be cleaned more effectively, maintaining its solar energy conversion rate.

[0021] The positioning frame is equipped with a cleaning transmission mechanism that drives two sets of cleaning guide modules to move in opposite directions on the photovoltaic panel. During the process of controlling the rotation and folding of the photovoltaic panel and the lateral movement of the moving bracket, the transmission rod can push the middle slider to move longitudinally. The middle slider drives the side sliders on both sides to move longitudinally synchronously through the crossbar, thereby realizing the synchronous driving of the cleaning guide modules on each photovoltaic panel to move synchronously, effectively achieving the cleaning effect on the surface of the photovoltaic panel.

[0022] The photovoltaic panel, after being rotated and folded, generates a windward angle, making it prone to swaying in strong winds. The photovoltaic panel in this application is equipped with a cleaning and guiding module on its surface. The cleaning and guiding modules on the surface of the rotated and folded photovoltaic panel are interconnected through secondary and primary curved springs. They are positioned laterally in front of the photovoltaic panel and the airflow is guided by the arc-shaped and straight guiding grooves on the surface of the guiding strips, reducing wind resistance on the photovoltaic panel surface, avoiding the generation of a large amount of turbulence on the photovoltaic panel surface, and improving the overall stability of the photovoltaic panel after rotation and folding.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1: Please refer to Figures 1-7The present invention provides the following technical solution: a photovoltaic energy-saving curtain wall based on a renewable energy system, comprising a longitudinal beam assembly 1 installed on the exterior wall of a building, a transverse beam assembly 2 vertically installed on the longitudinal beam assembly 1, and a positioning frame 3 sealed between the longitudinal beam assembly 1 and the transverse beam assembly 2. The renewable energy system in the positioning frame 3 includes a folded photovoltaic power generation module 4 and a clean energy diversion module 5; the folded photovoltaic power generation module 4 converts renewable solar energy into electrical energy, and the folded photovoltaic power generation module 4 includes a fixing strip 41 centrally fixedly installed in the positioning frame 3, and the positioning frame 3 is positioned relative to the fixing strip 41. Two sets of movable strips 42 are symmetrically installed on the positioning frame 3. The movable strips 42 are fitted and slidably installed in the positioning frame 3. Two sets of photovoltaic panels 43 are set between the movable strips 42 and the positioning frame 3. The two sets of photovoltaic panels 43 are rotatably connected to each other, and the other side of the two sets of photovoltaic panels 43 is rotatably connected to the movable strips 42 and the fixed strips 41 respectively. The positioning frame 3 is equipped with a power mechanism to drive the photovoltaic panels 43 to rotate and fold. The cleaning and guiding module 5 is used to clean the dust on the surface of the photovoltaic panels 43 and improve the solar energy conversion rate. The cleaning and guiding module 5 is segmented and attached to the surface of the folded photovoltaic power generation module 4.

[0044] Please see Figures 4-9 The power mechanism includes a transverse slide groove 44 horizontally opened on the positioning frame 3, and a movable bracket 45 slidably connected in the transverse slide groove 44. The movable bracket 45 is fixedly connected to the movable strip plate 42. Two sets of support frames 46 are fixedly installed on the back of the positioning frame 3. A threaded rod 47 is rotatably connected in the upper support frame 46, and a bidirectional power motor 48 is fixedly installed in the upper support frame 46. The threaded rod 47 is connected to the output end of the bidirectional power motor 48. A cylindrical rod 49 is fixedly installed in the lower support frame 46. The movable bracket 45 is slidably sleeved on the outside of the cylindrical rod 49, and the upper part of the movable bracket 45 is threadedly connected to the threaded rod 47.

[0045] The photovoltaic curtain wall is installed on the exterior wall of the building through the longitudinal beam assembly 1 and the transverse beam assembly 2. After installation, the state of the foldable photovoltaic power generation module 4 set in the positioning frame 3 can be controlled according to the needs of building ventilation, lighting and light energy conversion rate. It includes two states: fully unfolded to cover the positioning frame 3 and rotated folded to partially cover the positioning frame 3.

[0046] The bidirectional motor 48 controls the rotation of the threaded rod 47. The movable bracket 45 is threaded onto the outside of the threaded rod 47. Under the threaded transmission, the movable bracket 45 can slide laterally along the transverse slide groove 44. The two sets of threaded rods 47 in the support frame 46 have opposite thread directions. Under the threaded transmission, the two sets of movable brackets 45 on the positioning frame 3 move in opposite directions. The movable bracket 45 drives the movable strip 42 to move synchronously. When the movable strip 42 is fitted into the positioning frame 3 and moves laterally, the two sets of photovoltaic panels 43 connected between the movable strip 42 and the fixed strip 41 rotate and protrude outward from the outside of the positioning frame 3. At this time, the movable strip 42 moves away from the inner wall of the positioning frame 3, and the partial space of the positioning frame 3 is in an open state. The folded photovoltaic panels 43 are separated from the positioning frame 3 at the top and bottom. Under the separation of the crossbeam assembly 2, there is a certain gap between the upper and lower adjacent photovoltaic curtain walls. The air volume can also enter the building through the gap, and the ventilation range is large. This part of the structure can meet the needs of building ventilation and lighting, and can also adjust the angle of the photovoltaic panel 43 according to the changes in light intensity and irradiation angle.

[0047] Example 2: Please refer to Figures 5-7 and Figure 11 Based on Embodiment 1, a cleaning guide module 5 and a cleaning transmission mechanism are also disclosed. The specific structure is as follows: two sets of cleaning guide modules 5 are symmetrically arranged about the horizontal central axis of the photovoltaic panel 43, and a cleaning transmission mechanism is provided on the positioning frame 3 to drive the two sets of cleaning guide modules 5 to move in opposite directions on the photovoltaic panel 43.

[0048] Please see Figures 11-18 The cleaning and flow guiding module 5 includes a lifting frame 51 arranged parallel to the front of the photovoltaic panel 43. Rollers 52 are rotatably mounted on the lifting frame 51, rolling and adhering to the surface of the photovoltaic panel 43. Two sets of lifting frames 51 are symmetrically arranged about the longitudinal central axis of the photovoltaic panel 43, and a flow guiding strip 53 is fixedly installed between the two sets of lifting frames 51. Two sets of scraper strips 54 are fixedly installed on the flow guiding strips 53, adhering to the surface of the photovoltaic panel 43. An embedded groove 55 is formed on the flow guiding strip 53, and a guide rod 56 is fixedly installed on the front surface of the photovoltaic panel 43. The flow guiding strip 53 is slidably engaged with the guide rod 56 through the embedded groove 55. The side of the guide strip 53 away from the photovoltaic panel 43 is arc-shaped. Multiple arc-shaped guide grooves 15 are evenly spaced on the outer arc surface of the guide strip 53, and multiple straight guide grooves 16 that are connected to the arc-shaped guide grooves 15 are evenly spaced on the guide strip 53. The straight guide grooves 16 are longitudinally opened on the guide strip 53.

[0049] Please see Figures 4-12The cleaning transmission mechanism includes two sets of intermediate slides 6 symmetrically arranged on a fixed plate 41 along the transverse central axis, with intermediate sliders 7 slidably installed in the intermediate slides 6; two sets of side slides 8 symmetrically arranged on a movable plate 42 along the transverse central axis, with side sliders 9 slidably installed in the side slides 8. A crossbar 10 is fixedly installed on the intermediate slider 7, and the side sliders 9 are slidably installed outside the crossbar 10; a protrusion 11 is fixedly installed on the intermediate slider 7, and a transmission support rod 12 is rotatably connected to the protrusion 11, with the other end of the transmission support rod 12 rotatably connected to the movable bracket 45. The surfaces of the side sliders 9 and the side slides 8 are elastically connected to the lifting frame 51 in front of the adjacent photovoltaic panel 43 through a secondary curved spring piece 14, and the two sets of lifting frames 51 corresponding to the joint of the two sets of adjacent photovoltaic panels 43 are elastically connected through a main curved spring piece 13.

[0050] During the rotation and folding of the photovoltaic panel 43, the cleaning and flow guiding module 5 on its surface rotates synchronously with it. The cleaning and flow guiding module 5 is elastically adjusted in position through the main curved spring 13 and the secondary curved spring 14 connected on the outside, so that it always fits against the surface of the photovoltaic panel 43. The purpose of surface cleaning can be achieved when the photovoltaic panel 43 is rotated and folded to any state.

[0051] During the process of the movable bracket 45 moving to provide power for the rotation and folding of the photovoltaic panel 43, the two ends of the transmission rod 12 connected between the movable bracket 45 and the protrusion 11 rotate accordingly. When the transmission rod 12 rotates, it can push the protrusion 11 and the middle slider 7 to move longitudinally, so that the middle slider 7 moves longitudinally along the direction of the middle slide rail 6. During the longitudinal movement of the middle slider 7, it drives the crossbar 10 to move synchronously. The side slider 9 is slidably sleeved on the outside of the crossbar 10. The crossbar 10 can drive the side slider 9 to move downward synchronously, and move laterally on the movable strip 42. During the process, the side slider 9 is mounted on the outside of the crossbar 10 and slides laterally. As the side slider 9 and the middle slider 7 move longitudinally, they drive the cleaning guide module 5 to move longitudinally against the surface of the photovoltaic panel 43. The guide strip 53 in the cleaning guide module 5 is engaged with the inside of the guide rod 56 and moves longitudinally along the guide direction of the guide rod 56. The scraper 54 in the cleaning guide module 5 comes into contact with the dust on the surface of the photovoltaic panel 43. Its movement can achieve the purpose of cleaning the dust on the surface of the photovoltaic panel 43. Combined with the effect of rainwater on rainy days, it can effectively clean the dust on the surface of the photovoltaic panel 43.

[0052] After being rotated and folded, the photovoltaic panel 43 is placed in the positioning frame 3. The cleaning and guiding module 5 is placed horizontally in front of the photovoltaic panel 43. Through the main curved spring piece 13 and the secondary curved spring piece 14, it can strengthen the lateral connection of multiple folded photovoltaic panels 43, reduce the impact of wind resistance. In addition, the outer side of the guide strip 53 on the cleaning and guiding module 5 is arc-shaped. Through the arc-shaped guide groove 15 and the straight guide groove 16, it can guide the wind force, so that part of the wind force is guided to be parallel to the surface of the photovoltaic panel 43, further reducing the impact of wind resistance. This ensures that the photovoltaic panel 43 can be stably placed in the positioning frame 3 after being rotated and folded, thus maintaining the stability of the photovoltaic curtain wall installation and application.
