Description

Technical Field

[0001] This application relates to the field of curtain wall installation technology, and in particular to an adjustable photovoltaic curtain wall structure and construction method. Background Technology

[0002] A photovoltaic (PV) curtain wall is a type of building facade that uses photovoltaic panels, which generate electricity through the photoelectric effect under sunlight, as the building's curtain wall material. It provides green energy to buildings, is an effective way to reduce building energy consumption, and is one of the main technologies of building-integrated photovoltaics (BIPV). The PV glass in PV curtain walls typically uses crystalline silicon PV glass. Crystalline silicon PV glass can be divided into double-glass modules and single-glass modules based on the material on the back. Double-glass modules consist of solar cells and tempered glass laminated on both sides of the cells. Both the front and back of the double-glass module are transparent and capable of generating electricity, resulting in higher power generation efficiency and a longer lifespan.

[0003] In the current construction of photovoltaic curtain walls, a frame bracket is first installed on the exterior wall of the building, then double-glass photovoltaic modules are placed on the bracket, and finally a cover plate is fixed to the frame bracket with screws. The cover plate is then used to press the edges of the photovoltaic glass together, thereby installing the photovoltaic glass inside the frame bracket.

[0004] The aforementioned technologies primarily utilize a cover plate to press photovoltaic glass into a frame bracket for installation. However, the cover plate is fixed to the frame bracket with screws. Traditional screw connections make it difficult to control the pressure applied by the cover plate to the photovoltaic glass. If the screws are tightened too much, excessive pressure may cause micro-cracks in the outer tempered glass. Furthermore, excessive pressure transmitted to the solar cells inside the glass may increase the risk of micro-cracks in the cells, thus affecting power generation efficiency. Summary of the Invention

[0005] To facilitate control of the pressure applied to the photovoltaic glass during cover plate installation, this application provides an adjustable photovoltaic curtain wall structure and construction method, which adjusts the pressure of the cover plate on the photovoltaic glass by adjusting the pressure of the inner ring on the cover plate.

[0006] In the first aspect, this application provides an adjustable photovoltaic curtain wall structure, which adopts the following technical solution: An adjustable photovoltaic curtain wall structure includes a frame-shaped bracket connected to a wall, photovoltaic glass placed inside the frame-shaped bracket, a cover plate abutting against the outer wall of the photovoltaic glass, and a connecting assembly connecting the cover plate to the frame-shaped bracket. The connecting assembly includes an end threaded rod fixed to the frame-shaped bracket. The end threaded rod passes through the cover plate and is threadedly connected to an end mounting component. The end mounting component includes an inner ring threadedly connected to the end threaded rod and an outer cover coaxially sleeved outside the inner ring. The inner wall of the outer cover has a plurality of sliding grooves evenly formed along the radial direction of the inner ring. A plurality of locking blocks are slidably arranged in the sliding grooves along the radial direction of the inner ring. A dome is provided at one end of the locking block facing the inner ring, and a locking spring is fixedly provided at the end of the locking block away from the inner ring. A plurality of locking grooves are evenly formed on the outer circumference of the inner ring, and the dome can be inserted into the locking groove.

[0007] By adopting the above technical solution, the cover plate can be fixed to the frame bracket by the end threaded rod and the end mounting piece. The end mounting piece has two states during installation. The first state is that the inner ring and the outer cover are locked. In this state, rotating the outer cover can drive the inner ring to rotate at the same time, so that the inner ring can rotate on the end threaded rod and continuously move closer to the cover plate. The second state is that the inner ring and the outer cover are unlocked. When the inner ring is subjected to a specified amount of external force, it can no longer rotate. At this time, rotating the outer cover will cause the dome to retract into the sliding groove after being subjected to force. At this time, the two are unlocked. Rotating the outer cover cannot drive the inner ring to continue rotating. This realizes the control of the locking degree of the inner ring on the cover plate, and also realizes the control of the tightness of the cover plate against the photovoltaic glass, reducing the pressure on the glass and the pressure transmission to the photovoltaic structure inside the glass.

[0008] Optionally, an adjusting screw is rotatably provided in the sliding groove, the axis of the adjusting screw is parallel to the sliding direction of the corresponding clamping block, and an adjusting plate is threadedly connected to the adjusting screw. The adjusting plate can slide along the sliding direction of the clamping block and is connected to the inner wall of the sliding groove; the end of the clamping spring away from the clamping block is fixedly connected to the adjusting plate.

[0009] By adopting the above technical solution, rotating the adjusting screw can drive the adjusting plate to move back and forth in the sliding groove, thereby adjusting the position of one end of the clamping spring. After the length of the clamping spring changes, its force on the clamping block also changes accordingly, thereby adjusting the force range of the clamping block retracting into the sliding groove, thus adjusting the degree of tightness between the cover plate and the photovoltaic glass.

[0010] Optionally, an anti-disengagement plate is fixedly connected to the end of the adjusting screw near the clamping spring, and the cross-sectional area of ​​the anti-disengagement plate is larger than the cross-sectional area of ​​the adjusting screw.

[0011] By adopting the above technical solution, the probability of the adjusting block detaching from the adjusting screw during rotation is reduced, thereby reducing the risk of subsequent maintenance.

[0012] Optionally, a limiting block is fixedly provided on the inner wall of the sliding groove near the inner ring, and the clamping block abuts against the limiting block near the side wall of the inner ring.

[0013] By adopting the above technical solution, the limiting block plays a limiting role on the clamping block. When the inner ring and the outer cover are unlocked and separated, the clamping block will not fall out of the sliding groove. This allows the outer cover to be removed and reused after the inner ring is installed, and also reduces the overall number of parts during the installation of the photovoltaic curtain wall.

[0014] Optionally, a plurality of observation slots are provided on the side wall of the outer cover facing the photovoltaic glass. The observation slots and the sliding slots are interconnected, and the extension direction of the observation slots is parallel to the sliding direction of the adjustment plate.

[0015] By adopting the above technical solution, operators can directly observe the position of the adjustment plate through the observation slot, which makes it easier to adjust the position more accurately and facilitates easier adjustment of the tightness between the cover plate and the photovoltaic glass.

[0016] Optionally, a scale is provided on the outer wall of the outer cover near the observation slot, and the side wall of the adjustment plate facing the observation slot is set in a bright color.

[0017] By adopting the above technical solution, the position of the adjustment plate is made easier to adjust, which is more conducive to adjusting the tightness between the cover plate and the photovoltaic glass.

[0018] Optionally, the frame bracket is also fitted with a baffle for shielding the end threaded rod and the end mounting piece.

[0019] By adopting the above technical solutions, the overall appearance is more aesthetically pleasing after installation.

[0020] Secondly, this application provides a construction method for an adjustable photovoltaic curtain wall structure, employing the following technical solution: A construction method for an adjustable photovoltaic curtain wall structure, employing the aforementioned adjustable photovoltaic curtain wall structure, includes the following steps: S1. Install the frame brackets: Arrange the frame brackets in sequence according to the arrangement requirements and install them on the exterior wall of the building; S2. Place the photovoltaic glass and complete the wiring: Place the photovoltaic glass in the frame bracket, and at the same time complete the wiring of the positive and negative connector wires of the photovoltaic glass through the frame bracket. S3. Install the cover plate: Pass the cover plate through the end threaded rod and fix the cover plate with the end mounting piece. When fixing, rotate the outer cover to drive the inner ring closer to the cover plate until the outer cover and inner ring are unlocked. Then remove the outer cover. Repeat this process several times to install the cover plate in multiple positions on the frame bracket. The cover plate installation is now complete. S4. Install baffles: Install baffles on the frame bracket to cover the end threaded rods and inner rings, and make it look aesthetically pleasing.

[0021] In summary, this application includes the following beneficial technical effects: it can control the degree of locking of the end mounting component to the cover plate, thereby controlling the degree of tightness of the cover plate against the photovoltaic glass and reducing the pressure applied to the glass, which would lead to pressure transmission to the photovoltaic structure inside the glass.

[0030] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0031] This application discloses an adjustable photovoltaic curtain wall structure, referring to... Figure 1 and Figure 2 It includes a frame bracket 1 that can be connected to a wall, a photovoltaic glass 2 that can be placed inside the frame bracket 1, a cover plate 3 that can abut against the outer wall of the photovoltaic glass 2, and a connecting component that can connect the cover plate 3 to the frame bracket 1.

[0032] Reference Figure 2 and Figure 3 The frame-shaped support 1 includes several vertical supports 101 and several horizontal supports 102 perpendicular to the vertical supports 101. The vertical supports 101 are vertically arranged and hollow, with mounting brackets 103 fixedly connected to them. The mounting brackets 103 can be detachably connected to the building wall by bolts. The horizontal supports 102 are horizontally arranged and hollow, with both ends abutting against the opposite side walls of adjacent vertical supports 101. Tie bolts 104 pass through and are installed on both the horizontal supports 102 and the vertical supports 101 to fix their positions.

[0033] Reference Figure 2 and Figure 3 A limiting strip 105 is fixedly connected to the side wall of the horizontal support 102. The length direction of the limiting strip 105 is parallel to the length direction of the horizontal support 102. The vertical width of the limiting strip 105 is less than the vertical width of the horizontal support 102, and the limiting strip 105 is fixed to the middle of the side wall of the horizontal support 102. The horizontal length of the limiting strip 105 is greater than the horizontal length of the horizontal support 102, and both ends of the limiting strip 105 protrude beyond the corresponding ends of the horizontal support 102. A limiting groove 110 is also provided on the vertical support 101. The ends of the limiting strip 105 protruding beyond the horizontal support 102 can be inserted into the limiting groove 110, thereby strengthening the vertical limiting of the horizontal support 102. The limiting strip 105, the horizontal support 102, and the vertical support 101 together form a rectangular receiving groove 107 for placing the photovoltaic glass 2. A wiring hole 108 is also provided on the side wall of the vertical support 101 that abuts against the photovoltaic glass 2, so that the wires of the photovoltaic glass 2 can be routed through the vertical support 101.

[0034] Reference Figure 2 and Figure 3 The cover plate 3 is parallel to the length of the transverse support 102, and the transverse width of the cover plate 3 is not less than the transverse width of the limiting strip 105, while the vertical width of the cover plate 3 is greater than the vertical width of the limiting strip 105. The cover plate 3 can be fixedly connected to the transverse support 102 or the vertical support 101 via a connecting assembly. After being fixed, the inner wall of the cover plate 3 can abut against the side wall of the photovoltaic glass 2, thereby pressing the photovoltaic glass 2 tightly against the inner wall of the receiving groove 107.

[0035] Reference Figures 3 to 5Limiting holes 106 are provided at both ends of the limiting strip 105, in the middle of the limiting strip 105, and at both ends of the cover plate 3. The connecting assembly includes an end connecting part 4 for fixing the protruding ends of the cover plate 3 to the vertical bracket 101. The end connecting part 4 includes an end threaded rod 5 fixedly connected to the limiting groove 110 and an end mounting member 6 sleeved on the end threaded rod 5. The axis of the end threaded rod 5 is perpendicular to the plane of the cover plate 3. The end mounting member 6 is located on the side of the cover plate 3 away from the limiting strip 105. The end mounting member 6 can abut against the cover plate 3, thereby making the cover plate 3 abut against the photovoltaic glass 2.

[0036] Reference Figure 4 and Figure 5 The end mounting component 6 includes an inner ring 601 threadedly connected to the end threaded rod 5 and an outer cover 603 coaxially sleeved outside the inner ring 601. The outer circumferential wall of the inner ring 601 is evenly provided with several locking grooves 602. The inner circumferential wall of the outer cover 603 is evenly provided with several locking elements 604, each corresponding to a locking groove 602, and the locking elements 604 can be inserted into the locking groove 602. A mounting block 605 is also coaxially and fixedly connected to the side wall of the outer cover 603 away from the inner ring 601. The outer edge of the mounting block 605 is a regular polygon to facilitate the operator to screw the outer cover 603. When the operator turns the mounting block 605, the outer cover 603 can rotate. Under the action of the clamping part 604 and the clamping groove 602, the outer cover 603 can also drive the inner ring 601 to rotate on the threaded rod, so that the inner ring 601 continuously approaches the cover plate 3 until it is pressed against the cover plate 3, thereby fixing the cover plate 3, photovoltaic glass 2 and limiting strip 105 with the inner ring 601.

[0037] Reference Figure 5 To ensure a more secure fixation of the photovoltaic glass 2, the depth of the receiving groove 107 can be less than the thickness of the photovoltaic glass 2. This allows the outer wall of the photovoltaic glass 2 to protrude beyond the outer wall of the limiting strip 105 when it is placed in the receiving groove 107. Consequently, when the cover plate 3 is pressed against the photovoltaic glass 2, the obstruction effect of the vertical support 101 or the limiting strip 105 on the cover plate 3 can be reduced.

[0038] Reference Figure 5 and Figure 6To adjust the tightness between the inner ring 601 and the outer cover 603, several sliding grooves 606 are evenly formed on the inner circumference of the outer cover 603. Each sliding groove 606 corresponds to a locking groove 602. The locking member 604 can slide radially along the inner ring 601 and is connected to the sliding groove 606. The locking member 604 includes a locking block 607 that slides radially along the inner ring 601 and is connected to the sliding groove 606. Simultaneously, an adjusting screw 608 is rotatably mounted on the inner wall of the sliding groove 606 away from the inner ring 601. The axis of the adjusting screw 608 is parallel to the sliding direction of the locking block 607. One end of the adjusting screw 608, protruding from the outer cover 603, is fixedly connected to an adjusting head 609. The outer wall of the adjusting head 609 has a cross-shaped groove for rotation using a flathead screwdriver or a Phillips head screwdriver. An adjusting screw 608 passes through and is threadedly connected to an adjusting plate 610. The adjusting plate 610 can slide along the extension direction of the sliding groove 606 and is connected to the inner wall of the sliding groove 606. An anti-detachment plate 611 is coaxially fixedly connected to the end of the adjusting screw 608 away from the adjusting head 609. The cross-sectional area of ​​the anti-detachment plate 611 is larger than that of the adjusting screw 608. A clamping spring 612 is fixedly connected between the adjusting plate 610 and the clamping block 607. The extension axis of the clamping spring 612 is parallel to the sliding direction of the clamping block 607, and the inner diameter of the clamping spring 612 is larger than the diameter of the anti-detachment plate 611. The anti-detachment plate 611 and part of the adjusting screw 608 can be located in the gap in the middle of the clamping spring 612.

[0039] Reference Figure 4 and Figure 6 A limiting block 613 is fixedly installed on the inner wall of the sliding groove 606 facing the inner ring 601. The side wall of the clamping block 607 away from the clamping spring 612 can abut against the limiting block 613, thereby reducing the probability of the clamping block 607 disengaging from the sliding groove 606. A connector 614 is fixedly installed on the side wall of the clamping block 607 away from the clamping spring 612. The connector 614 can pass through and slide to connect with the limiting block 613. A dome 615 is fixedly installed on the side wall of the connector 614 away from the clamping spring 612. The dome 615 can be inserted into the clamping groove 602 of the inner ring 601. The operator can adjust the position of the clamping plate to adjust the supporting force of the clamping spring 612 on the clamping block 607, thereby adjusting the clamping degree between the inner ring 601 and the outer cover 603. The dome 615 is designed so that once the inner ring 601 is fixed in position, the outer cover 603 can be removed. After the outer cover 603 is removed, it becomes... Figure 3 The state of the threaded rod at the middle end 5 is adjusted to reduce the total number of parts to be installed.

[0040] Reference Figure 4 and Figure 6To facilitate observation of the clamping plate's position, an observation groove 616 is provided on the side wall of the outer cover 603 away from the mounting block 605. The observation groove 616 communicates with the sliding groove 606, and its extension direction is parallel to the sliding direction of the adjusting plate 610. A scale 617 is also provided on the side wall of the outer cover 603 near the observation groove 616. Simultaneously, the side wall of the adjusting plate 610 facing the observation groove 616 is painted a bright color to facilitate operator observation of the clamping plate's position.

[0041] Reference Figure 2 and Figure 7 The connecting assembly also includes a central connecting portion 7 for fixing the middle part of the cover plate 3 to the transverse support 102. The central connecting portion 7 includes a central threaded rod 8 fixedly connected to the middle part of the cover plate 3, with the axis of the central threaded rod 8 perpendicular to the plane of the cover plate 3. The free end of the central threaded rod 8 can pass through the limiting strip 105 and into the transverse support 102. One end of the central threaded rod 8 inserted into the transverse support 102 is also threadedly connected to a central mounting member 9. The central mounting member 9 has the same structure as the end mounting member 6, thereby connecting the middle part of the cover plate 3 to the transverse support 102 to enhance the connection strength of the cover plate 3. Simultaneously, an operating hole 10 is provided on the bottom side wall of the transverse threaded rod to facilitate operation of the central mounting member 9 by the operator.

[0042] Reference Figure 2 A baffle 109 is also attached to the vertical bracket 101. The baffle 109 can cover the end connection part 4, so that the frame bracket 1 is more beautiful and neat after installation.

[0043] This application also discloses a construction method for an adjustable photovoltaic curtain wall structure, including the following steps: S1. Install frame bracket 1: s1.1 Install vertical brackets 101: Arrange several vertical brackets 101 in sequence according to the arrangement requirements, and fix the mounting bracket 103 to the exterior wall of the building with expansion bolts; s1.2 Install the horizontal bracket 102: First, insert the portion of the limiting strip 105 protruding from the horizontal bracket 102 into the limiting grooves 110 of the two adjacent vertical brackets 101. At the same time, let the end threaded rod 5 pass through the limiting hole 106 of the limiting strip 105. Then, pass the tie bolt 104 through both the vertical bracket 101 and the horizontal bracket 102 to fix and connect them to form a frame bracket 1 and form a receiving groove 107. S2. Place photovoltaic glass 2 and complete wiring: Place photovoltaic glass 2 in the receiving groove 107, and at the same time pass the positive and negative connector wires of photovoltaic glass 2 through the wiring hole 108 and complete the wiring through the vertical bracket 101. S3. Install cover plate 3: Pass the end threaded rod 5 through the limiting hole 106 at the end of cover plate 3, and at the same time, pass the middle threaded rod 8 in the middle of cover plate 3 through the limiting hole 106 in the middle of limiting strip 105. Then, install cover plate 3 onto frame bracket 1 through end connecting part 4 and middle connecting part 7. The specific installation steps are as follows. s3.1 Adjust the position of the adjusting plate 610 by rotating the adjusting screw 608 with a screwdriver to adjust the supporting force of the clamping spring 612 on the clamping block 607, thereby adjusting the clamping degree of the inner ring 601 and the outer cover 603; and adjust the clamping degree of the inner ring 601 and the outer cover 603 in all end mounting parts 6 and middle mounting parts 9 using the above method. s3.2 The end mounting piece 6 is fitted onto the end threaded rod 5, and the outer cover 603 is rotated to drive the inner ring 601 to be threadedly connected to the end threaded rod 5. The outer cover 603 is continuously rotated to make the inner ring 601 abut against the cover plate 3 until the clamping piece 604 retracts into the sliding groove 606, causing the outer cover 603 and the inner ring 601 to be unlocked. At this time, the rotation of the outer cover 603 will no longer drive the inner ring 601 to approach the cover plate 3, thereby controlling the pressure between the inner ring 601 and the cover plate 3, and realizing the control of the pressing pressure of the photovoltaic glass 2 during the installation process. The end of the cover plate 3 is installed on the vertical bracket 101 repeatedly. s3.3 Using the same operating direction as in s3.2, the middle mounting part 9 is fitted onto the middle threaded rod 8, and the pressure between the middle mounting part 9 and the transverse support 102 is adjusted, thereby controlling the pressure of the middle part of the cover plate 3 on the photovoltaic glass 2; S4. Install baffle 109: Remove the outer cover 603 from the end mounting piece 6 and the middle mounting piece 9, and snap baffle 109 onto the vertical bracket 101 to cover the end threaded rod 5 for aesthetic purposes.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
