Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic curtain walls, and in particular to a distributed photovoltaic integrated building curtain wall structure. Background Art

[0002] Photovoltaic integrated building curtain walls (also known as photovoltaic curtain walls) are a technology that integrates solar power generation (photovoltaic) products into building curtain walls. The design of a photovoltaic curtain wall requires consideration of cells, formwork, wiring, and transformers. Cells form the formwork, which in turn is divided into small cells connected by wiring. All of these wiring forms a PV transformer. A PV transformer is a closed curtain wall component, and each photovoltaic system can consist of one or more transformers. Each photovoltaic system first generates direct current (DC) electricity, which is then converted to alternating current (AC) for transmission via the power grid. An inverse rectifier then converts the 230 / 400 volt voltage into electrical energy, typically at a frequency of 50 Hz. Crystalline cells are interconnected by wiring and connected to the large-surface formwork. These cells are embedded in a rigid resin glass panel, with wiring attached to the back or edge of the glass panel. Amorphous, as a component of the formwork, is a completely flat, interconnected surface embedded between two panes of glass and a highly transparent resin panel.

[0003] Existing photovoltaic curtain wall products have low photovoltaic conversion efficiency, typically less than 20%, due to the limited daily sunlight exposure, most of which is indirect. Furthermore, the photovoltaic curtain wall deprives the building interior of natural light, requiring increased indoor lighting intensity, further reducing the practical value of the photovoltaic curtain wall.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] For example 1, please refer to Figures 1-8 A distributed photovoltaic integrated building curtain wall structure includes a building wall 100, a curtain wall back panel 110 is provided on the building wall 100, and a plurality of mounting slots 120 are opened on the curtain wall back panel 110, and the plurality of mounting slots 120 are distributed in a rectangular array along the X-axis and Y-axis directions; A photovoltaic curtain wall assembly 200 is installed in each of the mounting slots 120. The photovoltaic curtain wall assembly 200 includes a curtain wall frame 210. Glass plates 220 and reflectors 230 are respectively installed at both ends of the curtain wall frame 210. A photovoltaic cell panel 240 is installed between the glass plates 220 and the reflectors 230. A first driving mechanism 400 and a second driving mechanism 600 are also provided on the building wall 100. The first driving mechanism 400 is used to drive several photovoltaic curtain wall components 200 to rotate based on the X axis, and the second driving mechanism 600 is used to drive several photovoltaic curtain wall components 200 to rotate based on the Y axis.

[0031] In this embodiment, the building wall surface 100 is used to represent a building wall. In the figure, the X-axis direction corresponds to the left-right direction, the Y-axis direction corresponds to the up-down direction, and the Z-axis direction corresponds to the front-back direction.

[0032] The curtain wall back panel 110 may be composed of a curtain wall embedded panel, adapters, a back panel, hanging parts, etc., as a conventional curtain wall installation structure, which will not be described in detail.

[0033] The curtain wall back panel 110 has a number of rectangular mounting slots 120 arranged in a horizontal and vertical array. These slots 120 are used to support the photovoltaic curtain wall assemblies 200. The curtain wall frame 210 serves as the base for the photovoltaic curtain wall assemblies 200. The photovoltaic panels 240 are routed through the curtain wall frame 210, allowing each photovoltaic curtain wall assembly 200 to generate power independently. Ultimately, the circuits of several photovoltaic curtain wall assemblies 200 are connected in parallel and fed into an inverter. The wiring for the photovoltaic curtain wall assemblies 200 is also conventional and not shown in the figure.

[0034] The photovoltaic curtain wall assembly 200 can rotate based on its own left-right central axis or up-down central axis, so that the glass plate 220 or the reflector 230 can be aligned with the direction of light. When light passes through the glass plate 220 and hits the photovoltaic panel 240, the photovoltaic panel 240 can generate electricity. When light hits the reflector 230, it will be reflected and refracted into the room.

[0035] Example 2: This example is an improvement based on Example 1. For details, please refer to Figures 1-8 Two first rotating rods 300 are symmetrically arranged in the plurality of mounting grooves 120, and the first rotating rods 300 are distributed along the X-axis direction. Two first rotating grooves 310 are symmetrically opened on the plurality of curtain wall frames 210, and the first rotating grooves 310 are adapted to the first rotating rods 300; Two adjacent first rotating rods 300 are coaxially connected; The first driving mechanism 400 includes a limiting groove 410 opened on the building wall 100, and the limiting groove 410 is distributed along the Y-axis direction. A rack 420 is slidingly arranged in the limiting groove 410, and a first tooth portion 430 and a second tooth portion 440 are symmetrically arranged on the rack 420. A first gear 450 is provided on several first rotating rods 300 located on the side close to the first driving mechanism 400, and several first gears 450 are engaged with the second tooth portion 440.

[0036] The first driving mechanism 400 further includes a motor 460 disposed on the building wall 100 . A second gear 470 is disposed on the output shaft of the motor 460 . The second gear 470 is a half gear. The first tooth portion 430 and the second tooth portion 440 are both engaged with the second gear 470 . Two second rotating rods 500 are symmetrically arranged in the plurality of mounting grooves 120. The second rotating rods 500 are distributed along the Y-axis direction. Two second rotating grooves 510 are symmetrically opened on the plurality of curtain wall frames 210. The second rotating grooves 510 are adapted to the second rotating rods 500. Two adjacent second rotating rods 500 are coaxially connected, and several second rotating rods 500 located on the side close to the second driving mechanism 600 are all connected to the second driving mechanism 600. The structure of the second driving mechanism 600 is consistent with that of the first driving mechanism 400.

[0037] In this embodiment, two first rotating rods 300 are symmetrically mounted in the cavity of the mounting slot 120 for rotation. Except for the leftmost and rightmost first rotating rods 300, the other two adjacent first rotating rods 300 are coaxially fixed.

[0038] A first rotation groove 310 is provided on both the left and right sides of the curtain wall frame 210, and a limiting groove 410 is provided at the front end of the building wall 100. The rack 420 slides up and down along the limiting groove 410. A row of first teeth 430 is provided on the front inner wall of the rack 420, and a row of second teeth 440 is provided on the rear inner wall of the rack 420.

[0039] A first gear 450 is fixed to each of the first rotating rods 300 on the far right. Each of the first gears 450 meshes with the second tooth portion 440 but does not contact the first tooth portion 430. A second gear 470 is connected to the output shaft of the motor 460. The second gear 470 meshes with both the first tooth portion 430 and the second tooth portion 440, forming a reciprocating motion structure.

[0040] When the first rotating rods 300 are respectively inserted into the first rotating grooves 310, the motor 460 drives the second gear 470 to rotate clockwise or counterclockwise. When the second gear 470 is within the range of engagement with the first tooth portion 430, the second gear 470 does not contact the second tooth portion 440. At this time, the clockwise rotation of the second gear 470 drives the rack 420 to rise. The rising rack 420 drives the first gears 450 to rotate counterclockwise, thereby driving the photovoltaic curtain wall assemblies 200 to rotate counterclockwise along the X-axis. The counterclockwise rotation of the second gear 470 drives the rack 420 to descend. The descending rack 420 drives the first gears 450 to rotate clockwise, thereby driving the photovoltaic curtain wall assemblies 200 to rotate clockwise along the X-axis.

[0041] When the second gear 470 is within the meshing range with the second tooth portion 440, the second gear 470 is not in contact with the first tooth portion 430. At this time, clockwise rotation of the second gear 470 drives the rack 420 downward, thereby driving the photovoltaic curtain wall assemblies 200 to rotate clockwise along the X-axis. Counterclockwise rotation of the second gear 470 drives the rack 420 upward, thereby driving the photovoltaic curtain wall assemblies 200 to rotate counterclockwise along the X-axis. This function is to provide two control output modes within different rotation ranges of the second gear 470, thereby facilitating the precise operation of the motor 460 to control the rotation of the photovoltaic curtain wall assemblies 200.

[0042] Similarly, two second rotating rods 500 are symmetrically mounted in the cavity of the mounting slot 120 for vertical rotation. Except for the uppermost and lowermost second rotating rods 500, the other two adjacent second rotating rods 500 are coaxially fixed.

[0043] Second rotation slots 510 are provided on both the upper and lower sides of the curtain wall frame 210. The structure of the second driving mechanism 600 is consistent with that of the first driving mechanism 400. The structures corresponding to the first gears 450 in the first driving mechanism 400 are installed on the lowermost second rotating rods 500.

[0044] When the motor 460 is operated to rotate the photovoltaic curtain wall assemblies 200 until their glass panels 220 face forward, the photovoltaic curtain wall assemblies 200 are further rotated left and right, disengaging the first rotating rod 300 from the first rotating groove 310 and engaging the second rotating rod 500 with the second rotating groove 510. The operating principle is similar to that of a double-hinged window.

[0045] Similarly, the photovoltaic curtain wall assembly 200 can be controlled to rotate in the Y-axis direction through the second driving mechanism 600.

[0046] Example 3: This example is an improvement made on the basis of Example 2. For details, please refer to Figures 9-11 , also includes a photovoltaic curtain wall intelligent control method, the photovoltaic curtain wall intelligent control method includes: Construct a building lighting scheme model under different lighting conditions by simulating real scenes; Obtain a theoretical architectural lighting model that changes over time; In the non-intelligent control building lighting mode, the lighting habits of building residents are collected to generate a building memory lighting model; The architectural memory lighting model and the architectural theoretical lighting model are coupled to establish the architectural correction lighting model; In the intelligent control building lighting mode, the lighting scheme model is retrieved from the lighting scheme model library according to the building modified lighting model and executed, so that the photovoltaic curtain wall assembly 200 performs photovoltaic power generation in the shading mode of the glass plate 220, and the photovoltaic curtain wall assembly 200 controls the building lighting in the reflecting mode of the reflector 230.

[0047] In this embodiment, a non-intelligently controlled building lighting mode is divided, that is, human control.

[0048] In the intelligent control building lighting mode, various parameter combinations are simulated in advance and recorded in the database, so as to make a quick response to the real-time changing external lighting conditions of the building in actual situations, so that the lighting inside the building and the results of the residents' manual control are consistent.

[0049] Example 4: This example is an improvement made on the basis of Example 3. For details, please refer to Figures 9-11 , by simulating real scenes to construct architectural lighting solutions under different lighting conditions, including: Obtain architectural design drawings and real-life architectural structure, lighting point layout, decoration, and material parameters to create a three-dimensional building model; Conduct lighting simulation on the building 3D model to establish a building lighting scheme model library; Conduct lighting simulation on the building 3D model to establish a building lighting scheme model library including: Input the 3D building model into the light simulation scene and adjust the parameters of the sunlight source and cloud layer in the simulation scene; Set the A-type parameters of the sunlight source, including the light direction parameter A1, the light intensity parameter A2, and the ultraviolet intensity parameter A3; Set the B-type parameters of the cloud layer, including cloud amount parameter B1, position parameter B2 and thickness parameter B3; Set the C-type parameters of the building 3D model, including the opening and closing parameters C1, position parameters C2, and opening area parameters C3 of several lighting points; Arrange and combine the above specific parameters to generate several building lighting plans R1, R2...Rn; Graphic rendering of several building lighting schemes simulates the refraction and reflection of light in the internal environment of the building's 3D model, and obtains the light intensity distribution inside the building under different building lighting schemes, based on which a building lighting scheme model library is established; Specifically, assume that there are rooms S1, S2...Sn in the building; Among them, the average light intensity of any room Sm under the building lighting plan R1 is Hm1, the average light intensity under the building lighting plan R2 is Hm2... and the average light intensity under the building lighting plan Rn is Hmn; The theoretical daylighting model for buildings that changes over time includes: The optimal average light intensity is set according to the functional purposes of different rooms in the building, including the optimal average light intensity H11 of room S1, the optimal average light intensity H21 of room S2...the optimal average light intensity Hn1 of room Sn.

[0050] In this embodiment, the light simulation scene can be realized by various building natural lighting simulation software, such as PKPM-Daylight, and the specific working principle is not described in detail.

[0051] A 3D building model is constructed by restoring the light simulation scene. Sunlight sources and clouds with different parameter combinations are added to the scene. The parameters of the lighting points, i.e., the individual mounting slots 120, on the 3D building model are then arranged. This parameter arrangement process yields various foreseeable combinations, which are recorded as a building lighting solution model library. The average light intensity in each room under each building lighting solution is recorded as feature data.

[0052] Furthermore, a theoretically optimal average light intensity is set according to the functional purpose of each room in the building. According to the theoretically optimal average light intensity of each room, several models are retrieved from the building lighting solution model library as theoretical models for backup.

[0053] As an optional implementation scheme of a distributed photovoltaic integrated building curtain wall structure of the present application, collecting the lighting habits of building residents to generate a building memory lighting model includes: Obtain the average light intensity curve of different rooms in the building as it changes over time when residents independently adjust the building lighting every day within a period T; Calculate the mean curve of several average light intensity curves, place the several average light intensity curves and the mean curve in the same coordinate system one by one, and calculate the deviation area; Divide the average light intensity curves of several average light intensity curves whose deviation areas are less than the standard value q, calculate the mean of the curves and record them as the first building memory lighting model, including the first tendency average light intensity H12 of room S1, the first tendency average light intensity H22 of room S2, ..., the first tendency average light intensity Hn2 of room Sn; Several average light intensity curves with deviation areas greater than or equal to the standard value q are divided, and the mean of the curves is calculated and recorded as the second building memory lighting model, including the second tendency average light intensity H13 of room S1, the second tendency average light intensity H23 of room S2...the second tendency average light intensity Hn3 of room Sn.

[0054] In this embodiment, T can be set to ten days. Specifically, the sampling period can be updated seasonally based on day length, maintaining a time period with similar day lengths. For any room, the average light intensity curve for that room over time T is averaged to obtain a mean curve, and then the daily average light intensity curve is divided.

[0055] If the calculated value of the deviation area is less than q, it means that the average lighting curve of the day belongs to the daily habits of the residents and is classified into the first building memory lighting model. If the deviation area value is greater than or equal to q, it means that the lighting habits of the residents on that day are relatively special and is classified into the second building memory lighting model.

[0056] As an optional implementation scheme of a distributed photovoltaic integrated building curtain wall structure of the present application, coupling the building memory lighting model and the building theoretical lighting model to establish a building correction lighting model includes: Calculate the corrected average light intensity H1 of room S1, the corrected average light intensity H2 of room S2, and the corrected average light intensity Hn of room Sn, and establish a corrected lighting model for the building based on the calculated values. If any room Sm has a first trend average light intensity Hm2, then the corrected average light intensity Hm of the room Sm = Hm2; If the room Sm does not have the first trend average light intensity Hm2, then the corrected average light intensity Hm of the room Sm = Hm1; If the room Sm has a second trend average light intensity Hm3, then Hm=Hm3 in a certain time period within a week corresponding to Hm3, and Hm=Hm2 in the remaining time periods within the week.

[0057] In this embodiment: further, when establishing a building-corrected lighting model for any room, the existence of the second-trend average light intensity is premised on the existence of the first-trend average light intensity.
