Description

Technical Field

[0001] This application relates to the technical field of building curtain walls, and in particular to an energy-saving and green building curtain wall. Background Technology

[0002] A building curtain wall is a building envelope or decorative structure that does not share the load of the main structure. It is generally composed of panels and the supporting structure behind them. A building curtain wall is usually formed by laying several unitized curtain walls on the exterior surface of a building. Unitized curtain walls are assembled and produced in a factory, which has the comprehensive advantages of saving a lot of construction time, making it the most popular and advantageous curtain wall form in the construction field. According to the material, the panels include glass panels, metal panels, stone panels, ceramic panels, cement fiberboard, etc.

[0003] Currently, in order to meet the theme of green building, existing building curtain walls generally have photovoltaic panels installed inside them. These photovoltaic panels collect solar energy and convert it into electricity, avoiding the waste of solar energy and making a significant contribution to energy conservation and emission reduction.

[0004] In related technologies, photovoltaic panels may age or be damaged during long-term use. After damage, they need to be repaired or replaced by professionals. Photovoltaic panels are generally installed inside building curtain walls and are mostly fixed with screws and other components. During maintenance, maintenance personnel need to disassemble the photovoltaic panels. However, since building curtain walls are generally quite high, maintenance personnel need to work at height. Photovoltaic panels fixed with screws and other components are not easy to disassemble and reassemble, and the operation requires a lot of time and effort. Summary of the Invention

[0005] To address the problem of the inability to quickly install and remove photovoltaic panels inside building curtain walls during high-altitude operations, this application provides an energy-saving and green building curtain wall.

[0006] This application provides an energy-saving and green building curtain wall using the following technical solution: An energy-saving and green building curtain wall includes: A support beam is provided, on which a curtain wall shell is connected. A panel is provided on the curtain wall shell, and a photovoltaic panel is provided between the panel and the curtain wall shell. A docking assembly is installed in the internal cavity of the curtain wall shell. The docking assembly is used to install the photovoltaic panel in the internal cavity of the curtain wall shell. The docking assembly includes a fixed seat, a linkage seat, an abutment rod, and an abutment seat. The fixed seat is fixed to the bottom of the curtain wall shell cavity and has an installation cavity inside. The linkage seat is slidably engaged in the installation cavity, and a reset member is connected between the linkage seat and the fixed seat. The reset member is used to drive the linkage seat away from the bottom of the curtain wall shell cavity. The abutment rod is fixed at the center of one side of the linkage seat and partially passes through the fixed seat. The abutment rod is slidably connected to the fixed seat. The abutment seat is fixed at the bottom corner of the photovoltaic panel and is arranged one-to-one with the abutment rod. A locking component is disposed on one side of the fixed base. The locking component is connected to the linkage base so that when the linkage base moves, it drives the locking component to move, thereby locking or unlocking the abutment. A reinforcement component is disposed on one side of the fixing base, and the reinforcement component is used to connect and lock the curtain wall shell to the support beam.

[0007] By adopting the above technical solutions, the main function of the building curtain wall is realized by utilizing the overall structure composed of the curtain wall shell and panels, and the photovoltaic panels are protected. The photovoltaic panels are used to collect solar energy, thereby making the building curtain wall green and energy-saving.

[0008] When a photovoltaic panel needs to be repaired after it is damaged, pressing the photovoltaic panel will cause it to push the abutment rod and the linkage seat to slide together within the fixed seat, thereby controlling the locking component to release the lock on the abutment seat, which in turn releases the lock on the photovoltaic panel.

[0009] The installation of the docking components enables the photovoltaic panels to be quickly installed and removed from the curtain wall shell. During installation and removal, the linkage seat drives the snap-fit ​​plate to move, which allows the snap-fit ​​plate to quickly lock and unlock with the abutment seat, improving the installation and removal efficiency of maintenance personnel and saving time and effort.

[0010] Furthermore, as the linkage seat moves, it drives the reinforcement components to move synchronously. Through the sliding of the pins in the reinforcement components, the curtain wall shell and the support beam can be further locked, improving the structural strength between them and preventing the curtain wall shell from falling off the support beam.

[0011] Optionally, the locking assembly further includes a limiting seat, a support plate, and a snap-fit ​​plate. A rectangular slot is provided through the center of one side of the fixing seat. The limiting seat is slidably snapped into the rectangular slot, and one side of the limiting seat is fixed to the linkage seat. The support plate is fixed on the outer wall of the fixing seat and located at the edge of the rectangular slot, and two are symmetrically arranged. The snap-fit ​​plate has a C-shaped structure, and one end of the snap-fit ​​plate is rotatably connected between two adjacent support plates.

[0012] By adopting the above technical solution, the linkage seat enables the limiting seat to slide synchronously with the linkage seat within the fixed seat, thereby driving the snap-fit ​​plate to rotate. The rotation of the snap-fit ​​plate allows one end of it to quickly lock and separate from the abutment seat, realizing the rapid installation and removal of photovoltaic panels.

[0013] Optionally, the locking assembly further includes a limiting groove and a locking rod. The limiting groove is inclinedly disposed on the limiting seat, and the locking rod is connected to one end of the locking plate near the support plate, and the locking rod is slidably locked in the limiting groove.

[0014] By adopting the above technical solution, the inclined limiting groove allows the locking rod to slide along the trajectory of the limiting groove, thereby driving the locking plate to rotate synchronously, thus achieving locking and separation of the abutment seat.

[0015] Optionally, the docking assembly further includes a shaped sliding groove, a locking block, and a locking rod. The shaped sliding groove is recessed on the linkage seat. One end of the locking block is rotatably connected to the center of one side of the fixed seat. The locking rod is connected to the other end of the locking block and is slidably engaged in the shaped sliding groove.

[0016] By adopting the above technical solution, the locking rod can slide along the trajectory of the irregular sliding groove using the irregular sliding groove, and then cooperate with the locking block to lock the linkage seat in the fixed seat.

[0017] Optionally, the irregularly shaped groove is provided with an irregularly shaped protrusion that is the same shape as the irregularly shaped groove, and the irregularly shaped protrusion is offset from the irregularly shaped groove.

[0018] By adopting the above technical solution, the locking rod is limited by the staggered protrusions, so that the locking rod slides in a directional manner.

[0019] Optionally, an isolation plate is provided at the bottom of the internal cavity of the curtain wall shell, and the photovoltaic panel is located above the isolation plate.

[0020] By adopting the above technical solution, the photovoltaic panels are limited and supported by the isolation plate, and the overall thermal insulation effect of the curtain wall shell is improved by the isolation plate.

[0021] Optionally, the reset component is a reset spring, and both the fixed seat and the linkage seat have protrusions fixed on opposite sides, with the two protrusions located on the same axis, and the reset spring sleeved between the two protrusions.

[0022] By adopting the above technical solution, the elastic force of the return spring enables the linkage seat to be quickly reset. At the same time, the elastic force of the return spring also enables the locking rod to be firmly locked in the corresponding position in the irregular groove when the linkage seat is locked.

[0023] Optionally, the reinforcing component includes a rack, a driving bevel gear, and a driven bevel gear. The rack is fixed to one side of the linkage seat, and a through groove is provided on the fixed seat near the rack. The driving bevel gear is rotatably connected to the through groove along the direction of the rack and meshes with the rack. A round rod is provided at the center of the driven bevel gear. The driven bevel gear is rotatably connected to the through groove through the round rod and meshes with the driving bevel gear. The driving bevel gear and the driven bevel gear are perpendicular to each other.

[0024] By adopting the above technical solution, the linkage seat drives the rack to move synchronously, which in turn drives the active bevel gear to mesh and move together, and then drives the driven bevel gear to mesh and rotate synchronously through the active bevel gear.

[0025] Optionally, a linkage gear is coaxially fixed to one end of the round rod of the driven bevel gear, and a mating tooth plate is slidably connected inside the fixed seat, with the linkage gear meshing with one side of the mating tooth plate.

[0026] By adopting the above technical solution, the driven bevel gear drives the round rod to rotate, which in turn drives the linkage gear to rotate synchronously. The linkage gear drives the mating tooth plate to mesh and move together, so that the mating tooth plate can slide quickly to the corresponding position inside the curtain wall shell.

[0027] Optionally, two pins are symmetrically arranged on one side of the mating toothed plate, and a locking hole is provided on the support beam, with the pins being inserted into the locking hole on the support beam.

[0028] By adopting the above technical solution, the curtain wall shell can be firmly locked to the support beam by using the pin rod in conjunction with the support beam.

[0029] In summary, this application includes at least one of the following beneficial technical effects: 1. By using the docking components, maintenance personnel can press the photovoltaic panel when they need to disassemble and repair it. This causes the linkage seat to move within the fixed seat, which in turn drives the snap-fit ​​plate to lock and unlock quickly, improving the disassembly and assembly efficiency of maintenance personnel and saving time and effort. 2. By using the pins in the reinforcement components to cooperate with the support beams, the structural strength of the connection between the curtain wall shell and the support beams can be greatly improved, preventing the curtain wall shell from separating from the support beams and falling off, thus eliminating safety hazards; 3. The insulation board improves the overall thermal insulation effect of the curtain wall shell. At the same time, the luminescent glaze material on the insulation board allows the photovoltaic panel to collect the light emitted by the insulation board at night, resulting in high efficiency and energy saving.

[0039] Reference Figure 1-3An energy-saving and green building curtain wall includes a support beam 1, a curtain wall shell 3 connected to the support beam 1, a panel 2 covering the curtain wall shell 3, and a photovoltaic panel 4 disposed between the panel 2 and the curtain wall shell 3. The photovoltaic panel 4 collects solar energy to avoid energy waste, making the curtain wall conform to the theme of green building. A docking component 5 is installed in the internal cavity of the curtain wall shell 3, and a locking component 6 is connected to one side of the docking component 5. The docking component 5 controls the locking component 6 to quickly connect, lock, unlock, and separate the photovoltaic panel 4 from the curtain wall shell 3. A reinforcing component 7 is also provided on one side of the docking component 5. This improves the efficiency of maintenance personnel in disassembling and assembling the photovoltaic panel 4 while significantly reducing labor time and intensity, saving time and effort.

[0040] In this embodiment, four sets of docking components 5 are provided, and the docking components 5 are located at the four corners of the bottom of the cavity of the curtain wall shell 3. By setting four sets of docking components 5, the entire structure is more stable. In other embodiments, six, eight, or other numbers of docking components 5 may also be provided.

[0041] The docking assembly 5 includes a fixed base 51, a linkage base 52, a shaped sliding groove 53, a locking block 54, a locking rod 55, an abutment rod 56, and an abutment base 57. The fixed base 51 is fixed at the bottom corner of the cavity of the curtain wall shell 3, and an installation cavity is provided inside the fixed base 51. The linkage base 52 is slidably engaged in the installation cavity. The abutment rod 56 is fixed at the center of the side of the linkage base 52 away from the bottom of the curtain wall shell 3, and the end of the abutment rod 56 away from the linkage base 52 protrudes from the fixed base 51. The abutment rod 56 and the fixed base 51 slide freely between each other.

[0042] A contact seat 57 is fixedly connected at the bottom corner of the photovoltaic panel 4, and the contact seat 57 and the contact rod 56 are set in a one-to-one correspondence.

[0043] The irregularly shaped slide groove 53 is recessed on the linkage seat 52. One end of the locking block 54 is rotatably connected to the center of one side of the linkage seat 52, and the locking rod 55 is connected to the other end of the locking block 54. The locking rod 55 is slidably engaged in the irregularly shaped slide groove 53.

[0044] The abutment seat 57 is connected to the abutment rod 56, and then the abutment rod 56 pushes the linkage seat 52 to slide within the fixed seat 51.

[0045] The irregularly shaped slide groove 53 is provided with an irregularly shaped protrusion of the same shape as the slide groove 53, and the irregularly shaped protrusion is offset from the slide groove 53. The offset protrusion is used to limit the locking rod 55, so that the locking rod 55 slides in a directional manner. A reset element 58 is provided between the fixed base 51 and the linkage base 52. In this embodiment, the reset element 58 is a reset spring. A cylindrical protrusion is fixed on the opposite side of the fixed base 51 and the linkage base 52. The two protrusions are located on the same axis, and the reset spring is sleeved between the two protrusions.

[0046] In this embodiment, the locking component 6 includes a limiting seat 61, a limiting groove 62, a support plate 63, a snap-fit ​​plate 64, and a snap-fit ​​rod 65. A rectangular slot is provided through the center of one side of the fixed seat 51. The limiting seat 61 is slidably snapped into the rectangular slot, and one side of the limiting seat 61 is fixed to the linkage seat 52. The support plate 63 is fixed to the outer wall of the fixed seat 51 and located at the edge of the rectangular slot. Two support plates 63 are symmetrically arranged. The snap-fit ​​plate 64 has a U-shaped structure, and one end of the snap-fit ​​plate 64 is rotatably connected between two adjacent support plates 63. The limiting groove 62 is inclinedly arranged on the limiting seat 61. The snap-fit ​​rod 65 is connected to the end of the snap-fit ​​plate 64 near the support plate 63, and the snap-fit ​​rod 65 is slidably snapped into the limiting groove 62.

[0047] The inclined limiting groove 62 allows the locking rod 65 to slide along the trajectory of the limiting groove 62, thereby driving the support plate 63 to rotate synchronously. This allows one end of the support plate 63 to be locked and separated from the abutment seat 57, thus locking and unlocking the photovoltaic panel 4, which is convenient for maintenance personnel to operate.

[0048] An isolation plate 8 is installed at the bottom of the internal cavity of the curtain wall shell 3. The photovoltaic panel 4 is located above the isolation plate 8. The isolation plate 8 is made of high heat insulation material and coated with luminous glaze material. The isolation plate 8 improves the overall heat insulation effect of the curtain wall shell 3. At the same time, the luminous glaze material allows the photovoltaic panel 4 to collect the light emitted by the isolation plate 8 at night.

[0049] Reference Figure 4 and Figure 5 In this embodiment of the application, the reinforcement component 7 is disposed on the fixed seat 51 near the bottom of the cavity of the curtain wall shell 3, and the reinforcement component 7 is connected to the linkage seat 52, so that the sliding of the linkage seat 52 drives the support plate 63 and drives the reinforcement component to move synchronously.

[0050] The docking component 5 uses the fixed seat 51 to drive the support plate 63 to quickly lock and unlock the photovoltaic panel 4. At the same time, the fixed seat 51 moves and simultaneously drives the reinforcement component 7 to reinforce the connection between the curtain wall shell 3 and the support beam 1, thereby improving the structural strength of the connection between the curtain wall shell 3 and the support beam 1 and eliminating safety hazards.

[0051] In this embodiment, the reinforcing component 7 includes a rack 71, a driving bevel gear 72, a driven bevel gear 73, a linkage gear 74, a mating gear plate 75, and a pin 76. The reinforcing component 7 is used to reinforce the curtain wall shell 3 and the supporting beam 1 via the pin 76, thereby improving the height of the curtain wall shell 3 (combined with...). Figure 1 ) and support beam 1 (combined) Figure 1 The structural strength of the connection between the two.

[0052] The rack 71 has a helical tooth structure, which makes the meshing between the rack 71 and the driving bevel gear 72 more stable. Because traditional straight tooth grooves can easily lead to a small meshing area between the rack 71 and the driving bevel gear 72 during meshing, the meshing position may be damaged due to excessive force.

[0053] In this embodiment, the rack 71 is fixed to one side of the linkage seat 52, and a rectangular through slot is provided on the side of the fixed seat 51 near the rack 71. The driving bevel gear 72 is rotatably connected in the rectangular through slot along the direction of the rack 71 and meshes with the rack 71. A round rod is provided at the center of the driven bevel gear 73. The driven bevel gear 73 is rotatably connected in the rectangular through slot through the round rod and meshes with the driving bevel gear 72. The driving bevel gear 72 and the driven bevel gear 73 are perpendicular to each other. Two pins 76 are symmetrically arranged on one side of the mating tooth plate 75, and a locking hole is provided on the support beam 1. The pins 76 are inserted into the locking hole on the support beam 1.

[0054] The implementation principle of an energy-saving and green building curtain wall according to this application embodiment is as follows: First, the curtain wall shell 3 is fixed as a whole on the support beam 1. The support beam 1 is located on the exterior wall of the building. When it is necessary to inspect the photovoltaic panel 4, the panel 2 is opened and the photovoltaic panel 4 is pressed. The photovoltaic panel 4 pushes the abutment rod 56 and the linkage seat 52 to slide as a whole in the fixed seat 51, thereby causing the locking rod 55 to slide in the irregular groove 53. After the linkage seat 52 is unlocked, the linkage seat 52 drives the limiting seat 61 to slide synchronously under the elastic force of the return spring, thereby causing the locking rod 65 to slide in the limiting groove 62, so that... The support plate 63 rotates, causing one end of the support plate 63 to separate from the abutment seat 57, thereby allowing the photovoltaic panel 4 to be quickly separated from the curtain wall shell 3. While the linkage seat 52 slides, the rack 71 drives the active bevel gear 72 to mesh and move, thereby driving the driven bevel gear 73 to rotate synchronously. The driven bevel gear 73 drives the linkage gear 74 to rotate, and the linkage gear 74 drives the docking tooth plate 75 and the pin 76 to slide as a whole, causing the pin 76 to separate from the support beam 1. This allows maintenance personnel to separate the curtain wall shell 3 from the support beam 1.

[0055] 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.
