Description

Technical Field

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

[0002] In the field of construction, as people's awareness of energy utilization and environmental protection continues to increase, building photovoltaic integration technology has emerged and has developed rapidly. Building photovoltaic integration perfectly combines solar photovoltaic power generation with buildings, which not only meets the functional needs of buildings, but also makes full use of solar energy resources for power generation and reduces dependence on traditional energy.

[0003] In the existing technology, for the installation of a building's integrated photovoltaic curtain wall, the installers usually first install beams and columns on the wall. The beams and columns are interwoven to form a frame, and tempered glass is filled in these frames. The tempered glass in multiple frames together constitutes the curtain wall. In order to improve resource utilization and practice environmental protection concepts, photovoltaic panels are generally installed in the columns. Photovoltaic panels absorb sunlight to generate electricity. Considering that the height of sunlight changes continuously throughout the day, resulting in different angles of light shining on the photovoltaic panels, a tracking mechanism is often set in the columns to enable the photovoltaic panels to continuously face the sun to absorb as much sunlight as possible, thereby improving the efficiency of photovoltaic power generation.

[0004] However, when the tracking device in the prior art is used for photovoltaic curtain walls, since the maintenance of photovoltaic panels is a high-altitude operation, it is very inconvenient for workers to perform maintenance on them, which greatly increases the difficulty of maintenance and reduces the maintenance efficiency. Summary of the Invention

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

[0006] The above-mentioned application objectives of this application are achieved through the following technical solutions:

[0007] A building photovoltaic integrated curtain wall system includes a mounting frame, a photovoltaic panel and a light-chasing assembly are provided within the mounting frame, a connector is provided between the light-chasing assembly and the photovoltaic panel to connect the two, the connector includes a guide rod fixed to the back of the photovoltaic panel and a guide sleeve fixed to the light-chasing assembly, the guide sleeve has an insertion cavity for inserting the guide rod, a limiting groove is provided on the outer wall of the guide rod, a limiting member is provided within the guide sleeve to engage with the limiting groove, and a driving member is provided at the end of the limiting member away from the guide rod to drive the limiting member to insert into or slide out of the limiting groove;

[0008] A sliding cavity is opened in the guide sleeve along its own axial direction, and the sliding cavity is provided with a sliding plate, one end of the sliding plate abuts against the limit piece, and the other end of the sliding plate is fixed with a ridge facing the side of the guide rod, and the end of the guide rod is provided with a limiting protrusion abutting against the ridge, and the sliding cavity is provided with a stopping end at the end away from the ridge for the sliding plate to slide and abut.

[0009] By adopting the above technical solution, photovoltaic panels and light-chasing components are arranged in the installation frame. The photovoltaic panels are equipped with light-chasing blocks, which can track sunlight and improve power generation efficiency. The light-chasing components can adjust the photovoltaic panels in the horizontal and pitch directions; the guide rod and the guide sleeve in the connector cooperate, and the limit groove on the outer wall of the guide rod is engaged with the limit piece in the guide sleeve to fix and limit the photovoltaic panel. When the photovoltaic panel is damaged and needs to be repaired, the staff controls the driving part through electricity to make the limit piece slide out of the limit groove, and then pulls the photovoltaic panel, the guide rod slides out of the plug-in cavity, and the limit protrusion on the guide rod abuts against the ridge to drive the sliding piece to slide, and the sliding After the sheet abuts the abutting end, the power is cut off, and the limit piece abuts against the top of the sliding sheet by its own gravity. The photovoltaic panel is continued to be pulled so that the limit protrusion slides over the ridge, and the photovoltaic panel can be removed for maintenance; after maintenance, the photovoltaic panel is installed, and the photovoltaic panel is pushed to insert the guide rod into the plug-in cavity. The limit protrusion abuts the ridge to drive the sliding sheet to slide, and when the limit protrusion slides over the ridge, the limit piece engages the limit groove again to complete the installation; when the power is off, the photovoltaic panel is locked, and it can be pulled for maintenance when the power is on. It is suitable for maintenance and inspection of curtain wall systems, and also facilitates maintenance operations for staff, thereby improving the maintenance efficiency of staff working at heights.

[0010] Preferably, the driving member includes a permanent magnet fixed to the end of the limiting member, and the driving member 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 the external circuit.

[0011] By adopting the above technical solution, the repulsive property of the permanent magnet and the electromagnet poles can be used to drive the limit piece to embed into the limit slot. When the staff is inspecting, they energize the electromagnet to change the magnetic poles, so that the permanent magnet and the electromagnet attract each other. Under the action of magnetic attraction, the permanent magnet drives the limit piece to slide out of the limit slot. The characteristics of the magnetic poles can be used to accurately control the clamping force between the limit piece and the limit slot, and the limit piece can be moved quickly through the repulsion and attraction of the magnetic poles.

[0012] Preferably, the distance between the abutting end and the outer wall of the limiting member in the axial direction of the guide sleeve is smaller than the length of the sliding sheet in the axial direction.

[0013] By adopting the above technical solution, when the staff inspects and pulls the photovoltaic panel, it can ensure that the upper end of the sliding piece can support the limit piece, reducing the risk that the end of the limit piece slides into the plug-in cavity and causes the guide rod to be unable to slide into the plug-in cavity subsequently, thereby ensuring the stability of the photovoltaic panel during the inspection process.

[0014] Preferably, the sliding sheet is annular, the sliding cavity is provided with a sliding groove connected to the plug-in cavity, and the ridge slides in the sliding groove.

[0015] By adopting the above technical solution, a sliding cavity is opened in the guide sleeve along the axial direction for the sliding of the annular sliding piece, and the sliding cavity is opened with a sliding groove connected to the plug-in cavity, and the ridge can slide in the sliding groove. This can ensure the stability of the sliding piece driven by the limiting protrusion to slide by abutting the ridge, reduce the risk of the sliding piece abutting the limiting protrusion under the action of its own gravity and blocking the sliding of the guide rod, improve the smoothness of the sliding of the limiting protrusion against the ridge, and ensure the effective transmission of the sliding piece movement by the guide rod when sliding.

[0016] Preferably, the distance between the sliding sheet and the outer wall of the guide rod is greater than the height of the limiting protrusion in the radial direction of the guide rod.

[0017] By adopting the above technical solution, the interference between the limiting protrusion of the guide rod and the end of the sliding piece can be avoided during the sliding process, ensuring that the sliding piece can slide smoothly in the guide sleeve and ensuring that the guide rod effectively transmits the movement of the sliding piece when sliding.

[0018] Preferably, the limiting groove is inclined, and the angle between the side of the limiting member that is opposite to the guide rod and slides into the guide sleeve and the outer wall of the guide rod is between 0° and 90°.

[0019] By adopting the above technical solution, when the staff repairs the photovoltaic panel, the limiting protrusion drives the ridge to make the end of the sliding piece abut against the resisting end, and the resisting end limits the sliding of the sliding piece. The inclined limiting piece can apply pressure to the sliding piece in the direction opposite to the sliding direction of the guide rod. Because the resisting end is located on the side of the limiting piece opposite to the sliding direction of the guide rod, it can abut the pressure applied by the limiting piece on the sliding piece, so that the sliding piece and the limiting piece are better limited and fixed, reducing the risk of sliding of the sliding piece.

[0020] Preferably, the limiting groove is an annular groove in the radial direction of the guide rod.

[0021] By adopting the above technical solution, the limit piece is embedded in the annular limit groove. This annular structure makes the connection between the limit piece and the limit groove more stable, preventing the connection from failing due to position offset when adjusting the angle of the photovoltaic panel; and after the staff has repaired the photovoltaic panel, there is no need to align the limit piece and the limit groove. Even if the guide rod moves in its own radial direction, the structure of the annular groove and the limit piece can maintain the connection between the two, thereby improving the staff's maintenance efficiency of the photovoltaic panel under the tracking system.

[0022] Preferably, the end of the guide rod is plugged into the end of the guide sleeve.

[0023] 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.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 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;

[0026] 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.

[0027] 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

[0036] The following is a further detailed description with reference to the accompanying drawings:

[0037] As attached Figure 1 and attached Figure 2 As shown, a building photovoltaic integrated curtain wall system includes a mounting frame 1, a photovoltaic panel 2 and a tracking component 3. The mounting frame 1 is made of aluminum profile and is fixed on the wall. There are multiple groups of mounting frames 1. The same group of mounting frames 1 includes two facing columns 12 and a beam 11 perpendicular to the columns 12. The beam 11 is fixed in the middle between the two columns 12, and photovoltaic glass 4 is respectively installed at the upper and lower ends of the beam 11 and between the columns 12.

[0038] The photovoltaic panel 2 is installed in the column 12. The photovoltaic panel 2 can absorb light to generate photovoltaic power. The chasing component 3 is installed in the column 12. A connector 5 is provided between the chasing component 3 and the photovoltaic panel 2. The chasing component 3 includes a horizontal motor 31 and a pitch motor 32. The horizontal motor 31 is fixed in the column 12. The horizontal motor 31 can adjust the photovoltaic panel 2 horizontally through the connector 5 and provide power for the horizontal adjustment of the photovoltaic panel 2 through its own operation. The horizontal motor 31 can adopt a three-phase asynchronous motor. This motor has a simple structure, reliable operation, and a pitch motor. The machine 32 is located above the horizontal motor 31. The pitch motor 32 adjusts the angle of the photovoltaic panel 2 in the pitch direction through the connecting piece 5. The pitch motor 32 can also be a stepper motor. The horizontal motor 31 and the pitch motor 32 cooperate with each other. The surface of the photovoltaic panel 2 is provided with a photosensor that automatically senses sunlight, which can detect the direction of sunlight in real time. Once the photosensor 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 pitch motor 32 or the horizontal motor 31 to adjust the angle of the photovoltaic panel 2 so that it is always facing the sunlight.

[0039] As attached Figure 3 and attached Figure 4As shown, the connector 5 is arranged between the pitch motor 32 and the photovoltaic panel 2, and plays a key role in connecting the two. The connector 5 includes a guide rod 51 and a guide sleeve 52. The guide rod 51 is fixed on the back of the photovoltaic panel 2. The guide rod 51 is usually made of stainless steel with good corrosion resistance. The guide sleeve 52 is fixed on the output end of the pitch motor 32. The guide sleeve 52 is provided with a plug-in cavity 521 for the guide rod 51 to be plugged in. This allows the guide rod 51 to be smoothly inserted into the guide sleeve 52, providing a basis for subsequent adjustment actions.

[0040] 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 distance that the photovoltaic panel 2 can be pulled out, which increases the space for pulling out the photovoltaic panel 2 and ensures that the staff has enough operating space during maintenance.

[0041] An annular limiting groove 511 is provided on the outer wall of the guide rod 51, and the limiting groove 511 is inclined. A limiting member 6 is provided in the guide sleeve 52 for the limiting groove 511 to be embedded. The limiting member 6 is in the shape of a rod that matches the limiting groove 511, so that the limiting member 6 and the limiting groove 511 are more stably connected, preventing the connection from failing due to position offset when adjusting the angle of the photovoltaic panel 2. The annular groove structure does not need to align the limiting member 6 and the limiting groove 511. Even if the guide rod 51 moves in its own radial direction, the annular groove structure can maintain the connection between the two.

[0042] The end of the limit member 6 away from the guide rod 51 is provided with a driving member 7 for driving the limit member 6 to embed into or slide out of the limit groove 511. The driving member 7 includes a permanent magnet 71 and an electromagnet 72. The permanent magnet 71 is fixed to the end of the limit member 6. The electromagnet 72 is facing the permanent magnet 71, and their magnetic poles repel each other. The electromagnet 72 is electrically connected to the 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 utilizing the magnetic repulsion force to drive the limit member 6 to embed into or slide out of the limit groove 511. When the staff is inspecting, they energize the electromagnet 72 to change the magnetic pole so that the permanent magnet 71 and the electromagnet 72 attract each other. Under the action of magnetic attraction, the permanent magnet 71 drives the limit member 6 to slide out of the limit groove 511. The magnetic pole characteristics can be used to accurately control the clamping force between the limit member 6 and the limit groove 511, and the limit member 6 can move quickly through the repulsion and attraction of the magnetic poles.

[0043] As attached Figure 5 and attached Figure 6 As shown, a sliding cavity 522 connected to the plug-in cavity 521 is provided in the guide sleeve 52 along its own axial direction, and an annular sliding plate 8 is provided in the sliding cavity 522. The sliding plate 8 can slide axially in the sliding cavity 522. A sliding groove 523 connecting the sliding cavity 522 and the plug-in cavity 521 is also provided between the sliding cavity 522 and the plug-in cavity 521. One end of the sliding plate 8 abuts against the outer wall of the limit member 6, and the other end is fixed with a ridge 81 facing one side of the guide rod 51, and the ridge 81 slides in the sliding groove 523.

[0044] The end of the guide rod 51 is provided with a limiting protrusion 512 in the circumferential direction, and the limiting protrusion 512 is in interference fit with the ridge 81. This structure enables the guide rod 51 to abut the ridge 81 and synchronously drive the sliding piece 8 to slide in the sliding cavity 522 when sliding into or out of the insertion cavity 521. The inner wall of the sliding cavity 522 provides support for the sliding piece 8 when sliding, so that the limiting protrusion 512 always acts on the ridge 81, reducing the risk of the sliding piece 8 abutting against the limiting protrusion 512 under the action of its own gravity and blocking the sliding of the guide rod 51, improving the smoothness of the sliding of the limiting protrusion 512 against the ridge 81, and ensuring that the guide rod 51 effectively transmits the movement of the sliding piece 8 when sliding.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] The implementation principle of this embodiment is:

[0050] 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.

[0051] When the photovoltaic panel 2 is damaged and needs to be repaired, the staff controls the electromagnet 72 in the column 12 corresponding to the damaged photovoltaic panel 2 through electric control, switches the magnetic poles of the electromagnet 72 through electric power, and then the electromagnet 72 and the permanent magnet 71 attract each other. Under the action of magnetic attraction, the limit member 6 slides out of the limit groove 511. At this time, the operator pulls the photovoltaic panel 2 again, and the guide rod 51 slides out of the plug-in cavity 521. The limiting protrusion 512 on the end of the guide rod 51 abuts the rib 81 and slides in the sliding groove 523. The movement of the rib 81 synchronously drives the sliding piece 8 to slide in the direction of sliding into the guide sleeve 52 against the guide rod 51. The end of the sliding piece 8 abuts against the abutting end 524, and then the staff cuts off the power. The control of magnet 72 changes the magnetic pole of electromagnet 72, and electromagnet 72 repels permanent magnet 71, and then electromagnet 72 drives limit piece 6 to press against the upper end of sliding piece 8 through permanent magnet 71. The inclined limit piece 6 can apply pressure to the sliding piece in the direction opposite to the sliding direction of guide rod 51. Because the abutting end 524 is located on the side of limit piece 6 in the direction opposite to the sliding direction of guide rod 51, it can abut the pressure applied by limit piece 6 on sliding piece 8, so that sliding piece 8 and limit piece 6 are better limited and fixed. When the staff continues to pull the photovoltaic panel 2, the limiting protrusion 512 at the end of guide rod 51 will interfere and slide over the ridge 81, and then the staff can complete the step of unlocking the photovoltaic panel 2 on the column 12, and then it can be repaired;

[0052] When the photovoltaic panel 2 needs to be installed after maintenance, the photovoltaic panel 2 is pushed to insert the guide rod 51 into the insertion cavity 521, and the limiting protrusion 512 abuts the ridge 81 to drive the sliding piece 8 to slide, so that the limiting member 6 no longer abuts the upper end of the sliding piece 8, and the limiting member 6 will slide and abut the outer wall of the guide rod 51. Under the continuous insertion of the guide rod 51, the limiting protrusion 512 will interfere and slide over the ridge 81, and the limiting member 6 will slide into the limiting groove 511 from the outer wall of the guide rod 51 again, and the limiting groove 511 is engaged with the limiting member 6, and the limiting protrusion 512 abuts against the ridge 81, completing the installation of the photovoltaic panel 2; when the power is off, the photovoltaic panel 2 is locked, and it can be pulled for maintenance when the power is on, which is suitable for curtain wall system maintenance and inspection, convenient for staff to carry out maintenance operations, and improves the maintenance efficiency of staff under high-altitude operations.

[0053] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of protection required by this application, they are protected by patent law.
