Description

Technical Field

[0001] This application relates to the technical field of curtain walls, and in particular to a building integrated photovoltaic curtain wall system. Background Art

[0002] In the construction field, with the continuous improvement of people's awareness of energy utilization and environmental protection, building integrated photovoltaic technology has emerged and developed rapidly. Building integrated photovoltaic combines solar photovoltaic power generation with buildings perfectly, which not only meets the functional requirements of buildings, but also can make full use of solar energy resources for power generation, reducing the dependence on traditional energy.

[0003] In the prior art, for the installation of building integrated photovoltaic curtain walls, usually, installers first install crossbeams and columns on the wall. The crossbeams and columns intersect with each other to form a framework. Tempered glass is filled in these frameworks. The tempered glass in multiple frameworks together constitutes the curtain wall. In order to improve resource utilization rate and practice the environmental protection concept, generally, photovoltaic panels are installed in the columns, and the photovoltaic panels are used to absorb sunlight to achieve power generation. Considering that the height of the sun changes continuously during the day, resulting in different angles of light irradiated on the photovoltaic panels, so usually, a light tracking mechanism is set in the columns to enable the photovoltaic panels to continuously face the sun, so as to absorb as much sunlight as possible, thereby improving the efficiency of photovoltaic power generation.

[0004] However, when the light tracking device in the prior art is applied to photovoltaic curtain walls, since the maintenance of photovoltaic panels belongs to high-altitude operations, when workers perform high-altitude maintenance on them, it makes it very inconvenient for workers to carry out maintenance on them, greatly increasing the maintenance difficulty and at the same time reducing the maintenance efficiency. Summary of the Invention

[0005] To facilitate the maintenance of a building integrated photovoltaic curtain wall with a light tracking system, a building integrated photovoltaic curtain wall system is provided.

[0006] The above application objectives of this application are achieved through the following technical solutions: A building integrated photovoltaic curtain wall system includes an installation frame. A photovoltaic panel and a light tracking component are arranged in the installation frame. A connecting piece for connecting the two is arranged between the light tracking component and the photovoltaic panel. The connecting piece includes a guide rod fixed on the back of the photovoltaic panel and a guide sleeve fixed on the light tracking component. A plugging cavity for inserting the guide rod is formed in the guide sleeve. A limiting groove is formed on the outer wall of the guide rod. A limiting member that is clamped with the limiting groove is arranged in the guide sleeve. A driving member for driving the limiting member to be embedded in or slide out of the limiting groove is arranged at one end of the limiting member away from the guide rod; A sliding cavity is formed in the guide sleeve along its own axial direction. A sliding piece is arranged in the sliding cavity. One end of the sliding piece abuts against a limiting piece. A convex rib is fixed on the other end of the sliding piece facing one side of the guide rod. A limiting protrusion that abuts against the convex rib is arranged at the end of the guide rod. And a resisting end for the sliding piece to slide and abut against is arranged at one end of the sliding cavity away from the convex rib.

[0007] By adopting the above technical solution, a photovoltaic panel and a light-tracking component are arranged in the installation frame. The photovoltaic panel is equipped with a light-tracking block, which can track sunlight and improve the power generation efficiency. The light-tracking component can adjust the photovoltaic panel in the horizontal and pitching directions. In the connecting piece, the guide rod cooperates with the guide sleeve. The limiting groove on the outer wall of the guide rod is clamped with the limiting piece in the guide sleeve, which can fix and limit the photovoltaic panel. When the photovoltaic panel is damaged and needs to be repaired, the staff uses the electric control driving piece to make the limiting piece slide out of the limiting groove, and then pulls the photovoltaic panel. The guide rod slides out of the insertion cavity. The limiting protrusion on the guide rod abuts against the convex rib to drive the sliding piece to slide. After the sliding piece abuts against the resisting end, the power is cut off. The limiting piece abuts against the upper part of the sliding piece by its own gravity. Continue to pull the photovoltaic panel to make the limiting protrusion slip over the convex rib by interference, and then the photovoltaic panel can be removed for repair. After the repair, install the photovoltaic panel. Push the photovoltaic panel to insert the guide rod into the insertion cavity. The limiting protrusion abuts against the convex rib to drive the sliding piece to slide. When the limiting protrusion slides over the convex rib, the limiting piece is clamped with the limiting groove again to complete the installation. The photovoltaic panel is locked when the power is off and can be pulled for repair when the power is on. It is applicable to the maintenance and inspection of the curtain wall system and is also convenient for the staff to carry out maintenance operations, improving the maintenance efficiency of the staff during high-altitude operations.

[0008] Preferably, the driving piece includes a permanent magnet fixed at the end of the limiting piece. The driving piece also includes an electromagnet facing the permanent magnet. The magnetic poles of the permanent magnet and the electromagnet repel each other, and the electromagnet is electrically connected to an external circuit.

[0009] By adopting the above technical solution, the characteristic that the magnetic poles of the permanent magnet and the electromagnet repel each other can be used to drive the limiting piece to be embedded in the limiting groove. When the staff performs maintenance, the electromagnet is energized to change the magnetic poles, so that the permanent magnet and the electromagnet attract each other. The permanent magnet drives the limiting piece to slide out of the limiting groove under the action of magnetic attraction. The clamping force between the limiting piece and the limiting groove can be accurately controlled by using the magnetic pole characteristics, and the limiting piece can be quickly moved through the repulsion and attraction of the magnetic poles.

[0010] Preferably, the distance between the resisting end and the outer wall of the limiting piece in the axial direction of the guide sleeve is less than the length of the sliding piece in the axial direction.

[0011] By adopting the above technical solution, when the staff performs maintenance on the photovoltaic panel and pulls the photovoltaic panel, it can be ensured that the upper end of the sliding piece can bear the limiting piece, reducing the risk that the end of the limiting piece slides into the insertion cavity and causes the subsequent inability of the guide rod to slide into the insertion cavity, and ensuring the stability during the maintenance process of the photovoltaic panel.

[0012] Preferably, the sliding piece is annular, the sliding cavity is provided with a sliding groove connected to the insertion cavity, and the convex rib slides in the sliding groove.

[0013] By adopting the above technical solution, a sliding cavity for the annular sliding piece to slide is axially formed in the guide sleeve, the sliding cavity is provided with a sliding groove connected to the insertion cavity, and the convex rib can slide in the sliding groove. This can ensure the stability of the limit protrusion driving the sliding piece to slide by abutting against the convex rib, reduce the risk that the sliding piece abuts against the limit protrusion under its own gravity and blocks the sliding of the guide rod, improve the smoothness of the limit protrusion abutting against the convex rib to slide, and ensure the effective transmission of the movement of the guide rod to the sliding piece when the guide rod slides.

[0014] Preferably, the distance between the sliding piece and the outer wall of the guide rod is greater than the height of the limit protrusion in the radial direction of the guide rod.

[0015] By adopting the above technical solution, it can avoid the interference between the limit protrusion and the end of the sliding piece during the sliding process of the guide rod, ensure that the sliding piece can slide smoothly in the guide sleeve, and guarantee the effective transmission of the movement of the guide rod to the sliding piece when the guide rod slides.

[0016] Preferably, the limiting groove is inclined, and the included angle between the side of the limiting member facing away from the direction in which the guide rod slides into the guide sleeve and the outer wall of the guide rod is between 0° and 90°.

[0017] By adopting the above technical solution, when the staff repairs the photovoltaic panel, the limit protrusion drives the convex rib to make the end of the sliding piece abut against the resisting end, and the resisting end restricts the sliding of the sliding piece. The inclined limiting member can exert a pressure on the sliding in the direction away from the direction in which the guide rod slides into. Since the resisting end is located on the side of the limiting member facing away from the direction in which the guide rod slides into, it can resist the pressure exerted by the limiting member on the sliding piece, so that the sliding piece and the limiting member are better limited and fixed, reducing the sliding risk of the sliding piece.

[0018] Preferably, the limiting groove is an annular groove in the radial direction of the guide rod.

[0019] By adopting the above technical solution, the limiting member is embedded in the annular limiting groove. This annular structure makes the clamping between the limiting member and the limiting groove more stable, preventing the clamping failure caused by the position deviation when adjusting the angle of the photovoltaic panel; moreover, after the staff repairs the photovoltaic panel, there is no need to align the limiting member and the limiting groove. Even if the guide rod moves in its own radial direction, the structure of the annular groove and the limiting member can maintain the clamping between the two, improving the maintenance efficiency of the staff for the photovoltaic panel under the light tracking system.

[0020] Preferably, the end of the guide rod is inserted into the end of the guide sleeve.

[0021] By adopting the above technical solution, the end of the guide rod is inserted into the end of the guide sleeve. The insertion distance of the guide rod in the guide sleeve determines the distance that the photovoltaic panel can be pulled out, which increases the space for pulling the photovoltaic panel out of the installation frame and ensures that the staff has enough operating space during maintenance.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The tracking module and tracking block work together to ensure that the photovoltaic panels automatically adjust their angle under different sunlight conditions, receiving stronger light and improving photovoltaic power generation efficiency; 2. The staff controls the driving member through electricity to make the limit member fit into or slide out of the limit groove. When the guide rod slides in or out of the guide sleeve, the limit protrusion abuts the rib to drive the sliding piece to slide. The guide rod slides out of the insertion cavity. The sliding piece abuts the abutting end to support the limit member, releasing the limit on the guide rod, and the photovoltaic panel can be pulled out of the installation frame for maintenance. The guide rod slides into the insertion cavity, the limit protrusion abuts the rib to drive the sliding piece to slide, the limit member slides into the limit groove, and the rib engages with the limit protrusion, completing the limit fixation of the photovoltaic panel, making it easier for staff to repair the photovoltaic panel. 3. The photovoltaic panels are locked when the power is off and can be pulled out for maintenance when the power is on. The photovoltaic panels remain locked during power outages, which is suitable for curtain wall system working conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following is a further detailed introduction in conjunction with the accompanying drawings of the specification: As shown in the attached Figure 1 and attached Figure 2 As shown, a building integrated photovoltaic curtain wall system includes an installation frame 1, photovoltaic panels 2 and a light tracking component 3. The installation frame 1 is made of aluminum profiles and is fixed on the wall. There are multiple groups of installation frames 1. The same group of installation frames 1 includes two opposite columns 12 and a cross beam 11 perpendicular to the columns 12. The cross beam 11 is fixed in the middle between the two columns 12, and photovoltaic glasses 4 are respectively installed between the upper and lower ends of the cross beam 11 and the columns 12.

[0026] The photovoltaic panels 2 are installed in the columns 12. The photovoltaic panels 2 can absorb sunlight for photovoltaic power generation. The light tracking component 3 is installed in the columns 12. A connecting member 5 connecting the two is provided between the light tracking component 3 and the photovoltaic panels 2. The light tracking component 3 includes a horizontal motor 31 and a pitching motor 32. The horizontal motor 31 is fixed in the column 12. The horizontal motor 31 can horizontally adjust the photovoltaic panels 2 through the connecting member 5 and provide power for the horizontal adjustment of the photovoltaic panels 2 through its own operation. The horizontal motor 31 can adopt a three-phase asynchronous motor, which has a simple structure and reliable operation. The pitching motor 32 is located above the horizontal motor 31. The pitching motor 32 adjusts the angle of the photovoltaic panels 2 in the pitching direction through the connecting member 5. The pitching motor 32 can also select a stepping motor. The horizontal motor 31 and the pitching motor 32 cooperate with each other. A photosensitive sensor for automatically sensing sunlight is provided on the surface of the photovoltaic panels 2, which can detect the direction of sunlight in real time. Once the photosensitive sensor detects a change in the position of sunlight, it will transmit a signal to the control system. After receiving the signal, the control system will command the pitching motor 32 or the horizontal motor 31 to adjust the angle of the photovoltaic panels 2 so that they are always facing the sunlight directly.

[0027] As shown in the attached Figure 3 and attached Figure 4 As shown, the connecting member 5 is arranged between the pitching motor 32 and the photovoltaic panels 2 and plays a key role in connecting the two. The connecting member 5 includes a guide rod 51 and a guide sleeve 52. The guide rod 51 is fixed on the back of the photovoltaic panels 2. The guide rod 51 is usually made of stainless steel material and has good corrosion resistance. The guide sleeve 52 is fixed at the output end of the pitching motor 32. A plugging cavity 521 for inserting the guide rod 51 is opened in the guide sleeve 52, which enables the guide rod 51 to be smoothly inserted into the guide sleeve 52 and provides a basis for subsequent adjustment actions.

[0028] The end of the guide rod 51 is inserted into the end of the guide sleeve 52. The insertion distance of the guide rod 51 in the guide sleeve 52 determines the retractable distance of the photovoltaic panels 2, increasing the retractable space of the photovoltaic panels 2 and ensuring sufficient operating space for maintenance personnel.

[0029] An annular limiting groove 511 is formed on the outer wall of the guide rod 51. The limiting groove 511 is inclined. A limiting member 6 for the limiting groove 511 to be embedded is provided in the guide sleeve 52. The limiting member 6 is rod-shaped and matches the limiting groove 511, making the clamping between the limiting member 6 and the limiting groove 511 more stable, preventing the clamping failure caused by position deviation when adjusting the angle of the photovoltaic panel 2. The annular groove structure does not require aligning the limiting member 6 with the limiting groove 511. Even if the guide rod 51 moves in its own radial direction, the annular groove structure can maintain the clamping between the two.

[0030] One end of the limiting member 6 away from the guide rod 51 is provided with a driving member 7 for driving the limiting member 6 to be embedded in or slide out of the limiting groove 511. The driving member 7 includes a permanent magnet 71 and an electromagnet 72. The permanent magnet 71 is fixed at the end of the limiting member 6. The electromagnet 72 faces the permanent magnet 71, and their magnetic poles repel each other. The electromagnet 72 is electrically connected to an external circuit. By controlling the magnitude and direction of the circuit current, the magnetic field strength and direction of the electromagnet 72 can be changed, thereby driving the limiting member 6 to be embedded in or slide out of the limiting groove 511 by using magnetic repulsion. When the staff performs maintenance, the electromagnet 72 is energized to change the magnetic poles, so that the permanent magnet 71 and the electromagnet 72 attract each other. The permanent magnet 71 drives the limiting member 6 to slide out of the limiting groove 511 under the action of magnetic attraction. The clamping force between the limiting member 6 and the limiting groove 511 can be accurately controlled by using the magnetic pole characteristics, and the limiting member 6 can move quickly through the repulsion and attraction of the magnetic poles.

[0031] As shown in the Figure 5 and Figure 6 figure, an axial sliding cavity 522 communicating with the insertion cavity 521 is provided in the guide sleeve 52 along its own axis. An annular sliding piece 8 is provided in the sliding cavity 522. The sliding piece 8 can axially slide in the sliding cavity 522. A sliding groove 523 communicating the two is also provided between the sliding cavity 522 and the insertion cavity 521. One end of the sliding piece 8 abuts against the outer wall of the limiting member 6, and a convex rib 81 is fixed on the other end facing the side of the guide rod 51, and the convex rib 81 slides in the sliding groove 523.

[0032] A limiting protrusion 512 is provided in the circumferential direction at the end of the guide rod 51. The limiting protrusion 512 is in interference abutment with the convex rib 81. This structure enables the limiting protrusion 512 to abut against the convex rib 81 to synchronously drive the sliding piece 8 to slide in the sliding cavity 522 when the guide rod 51 slides into or out of the insertion cavity 521. The inner wall of the sliding cavity 522 provides support for the sliding of the sliding piece 8, so that the limiting protrusion 512 always acts on the convex rib 81, reducing the risk that the sliding piece 8 abuts against the limiting protrusion 512 under its own gravity and blocking the sliding of the guide rod 51, improving the smoothness of the limiting protrusion 512 abutting against the convex rib 81 and ensuring the effective transmission of the movement of the guide rod 51 to the sliding piece 8 during sliding.

[0033] The distance between the sliding piece 8 and the outer wall of the guide rod 51 is greater than the height of the limiting protrusion 512 in the radial direction of the guide rod 51, which can avoid interference between the limiting protrusion 512 and the end of the sliding piece 8 during the sliding process of the guide rod 51, ensure that the sliding piece 8 can slide smoothly in the guide sleeve 52, and ensure that the guide rod 51 effectively transmits the movement of the sliding piece 8 when sliding.

[0034] As attached Figure 5 and attached Figure 7 As shown, an abutment end 524 for the sliding piece 8 to slide and abut is provided in the sliding cavity 522 at the end away from the sliding piece 8. When maintenance is required, the staff switches the magnetic poles of the electromagnet 72 through electric control, and the permanent magnet 71 and the electromagnet 72 attract each other, causing the limit member 6 to slide out of the limit groove 511. Then, the pull is continued, and the limit protrusion 512 on the guide rod 51 abuts against the ridge 81 to drive the sliding piece 8 to slide. After the sliding piece 8 abuts against the abutment end 524, the power is cut off, and the electromagnet 72 and the permanent magnet 71 repel each other, causing the lower end of the limit member 6 to abut against the top of the sliding piece 8, causing the limit protrusion 512 to slide over the ridge 81 with interference.

[0035] The angle between the side of the limit member 6 that slides into the guide sleeve 52 away from the guide rod 51 and the outer wall of the guide rod 51 is between 0° and 90°, and is preferably set to 45° here. When the staff is repairing, the limit protrusion 512 drives the ridge 81 to make the end of the sliding piece 8 abut against the abutting end 524, and the abutting end 524 limits the sliding of the sliding piece 8. The inclined limit member 6 can apply pressure to the sliding piece in the direction away from the sliding direction of the guide rod 51. Because the abutting end 524 is located on the side of the limit member 6 that slides into the direction away from the guide rod 51, it can abut the pressure applied by the limit member 6 on the sliding piece 8, so that the sliding piece 8 and the limit member 6 are better limited and fixed, reducing the risk of sliding of the sliding piece 8.

[0036] The distance between the blocking end 524 and the outer wall of the limit member 6 in the axial direction of the guide sleeve 52 is smaller than the length of the sliding plate 8 in the axial direction. When the staff drives the guide rod 51 to slide out of the plug-in cavity 521 during maintenance, it can ensure that the upper end of the sliding plate 8 can support the limit member 6, reducing the risk that the end of the limit member 6 slides into the plug-in cavity 521 and causes the guide rod 51 to be unable to slide into the plug-in cavity 521 subsequently, thereby ensuring stability during the maintenance process.

[0037] The implementation principle of this embodiment is: A photovoltaic panel 2 and a light-chasing assembly 3 are arranged within the mounting frame 1. The photovoltaic panel 2 is equipped with a light-chasing block to track sunlight and improve power generation efficiency. The light-chasing assembly 3 can adjust the photovoltaic panel 2 in horizontal and vertical directions. The light-chasing assembly 3 cooperates with the light-chasing block to ensure that the photovoltaic panel 2 automatically adjusts its angle under different sunlight conditions to receive stronger light. When the photovoltaic panel 2 is damaged and needs to be repaired, the staff controls the electromagnet 72 in the corresponding column 12 of the damaged photovoltaic panel 2 through electricity, switches the magnetic pole of the electromagnet 72 through electricity, and then the electromagnet 72 attracts the permanent magnet 71. Under the action of magnetic attraction, the limiting member 6 slides out of the limiting groove 511. At this time, the operator pulls the photovoltaic panel 2 again, and the guide rod 51 slides out in the plugging cavity 521. The limiting protrusion 512 at the end of the guide rod 51 abuts against the convex rib 81 and slides in the sliding groove 523. The movement of the convex rib 81 will synchronously drive the sliding piece 8 to slide in the direction away from the guide rod 51 and into the guide sleeve 52. The end of the sliding piece 8 will abut against the resisting end 524. Then the staff cuts off the control of the electromagnet 72, the magnetic pole of the electromagnet 72 changes, and the electromagnet 72 repels the permanent magnet 71. Then the electromagnet 72 drives the limiting member 6 to abut against the upper end of the sliding piece 8 through the permanent magnet 71. The inclined limiting member 6 can apply a pressure to the sliding in the direction away from the sliding direction of the guide rod 51. Since the resisting end 524 is located on one side of the limiting member 6 away from the sliding direction of the guide rod 51, it can abut against the pressure exerted by the limiting member 6 on the sliding piece 8, so that the sliding piece 8 and the limiting member 6 are better limited and fixed. The staff continuously pulls the photovoltaic panel 2, and the limiting protrusion 512 at the end of the guide rod 51 will slip over the convex rib 81 with interference. Then the staff can complete the unlocking step of the photovoltaic panel 2 on the column 12, and then perform maintenance on it; When the photovoltaic panel 2 needs to be installed after maintenance, push the photovoltaic panel 2 to insert the guide rod 51 into the plugging cavity 521. The limiting protrusion 512 abuts against the convex rib 81 to drive the sliding piece 8 to slide. Then the limiting member 6 no longer abuts against the upper end of the sliding piece 8, and the limiting member 6 will slide and abut against the outer wall of the guide rod 51. Under the continuous insertion of the guide rod 51, the limiting protrusion 512 will slip over the convex rib 81 with interference. At this time, the limiting member 6 slides into the limiting groove 511 from the outer wall of the guide rod 51 again. The limiting groove 511 is engaged with the limiting member 6, and the limiting protrusion 512 abuts against the convex rib 81 to complete the installation of the photovoltaic panel 2; the photovoltaic panel 2 is locked when powered off and can be pulled for maintenance when powered on, which is suitable for the maintenance and inspection of the curtain wall system, facilitates the maintenance operation of the staff, and improves the maintenance efficiency of the staff during high-altitude operations.

[0038] This specific embodiment is only an interpretation of the present application, and it is not a limitation of the present application. Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as they are within the scope required to be protected by the present application, they are protected by the Patent Law.
