Description

Technical Field

[0001] This utility model relates to the field of double-layer curtain wall technology, specifically a green building double-layer curtain wall based on photovoltaic panels. Background Technology

[0002] Double-layer curtain walls in green buildings are a building envelope system consisting of two layers of facades, with an air buffer layer in between. They have significant advantages such as high energy efficiency, environmental comfort, reasonable lighting, and sound insulation and noise reduction. They are one of the important sustainable technologies in green buildings. Green building double-layer curtain walls based on photovoltaic panels embed photovoltaic modules into the double-layer glass curtain wall structure to form an integrated system of "power generation + energy saving".

[0003] In the prior art, patent CN116122466A discloses a double-layer curtain wall structure for green and energy-saving buildings, including ventilation ducts, curtain wall mechanism and protective mechanism; ventilation ducts: the front surface of the vertical tubes is provided with air outlet pipes, which are all connected to the ventilation ducts; the front surface of the horizontal tubes of the ventilation ducts is provided with horizontal tubes, the upper surface of the horizontal tubes is provided with air outlet holes; the middle of the upper and lower surfaces of the horizontal tubes is provided with vertical tubes; the upper and lower ends of the vertical tubes are closed structures; and the left and right sides of the vertical tubes are provided with air inlets.

[0004] The double-layer curtain wall structure of this type of green and energy-saving building has some problems. For example, the spacing between the two layers of curtain walls is fixed. In different installation environments, the spacing requirements between the two layers of curtain walls vary due to different ventilation needs. The fixed spacing between the two layers of curtain walls cannot effectively meet the ventilation needs of the green and energy-saving building in this working environment. At the same time, the use of only cross-shaped support frames to support the curtain wall panels cannot achieve all-round protection for all curtain wall panels, affecting the stability of the curtain wall panels at the edges.

The connecting holes are installed in conjunction with the longitudinally adjacent connecting columns to achieve a stable connection between the cross support frame and the T-shaped support frame, or to achieve a quick and stable connection between two adjacent cross support frames.

[0010] Furthermore, the connecting mechanism also includes locking cylinders, each of which is sleeved on the outer surface of an adjacent fixed rod. The rear end of the outer surface of the fixed rod is provided with an external thread, and the interior of each locking cylinder is provided with an internal thread. The internal threads are engaged with the adjacent external threads, and the rear end of each locking cylinder is fitted with the sliding mouth inside the adjacent connecting handle to lock the position of the connecting handle, ensuring the stability of the connection between the cross support frame and the T-shaped support frame or the connection between two adjacent cross support frames.

[0011] Furthermore, each of the cross support frames and the T-shaped support frames is provided with a cross-shaped limiting plate at its front end, and a T-shaped limiting plate at its front end. Both the cross-shaped and T-shaped limiting plates have through holes at their center positions. Screws penetrate these through holes in the rear cross-shaped and T-shaped limiting plates. Limiting screws are fixedly connected to the center positions of the front surfaces of the front cross support frame and the two front T-shaped support frames. These limiting screws also penetrate these through holes in the front cross-shaped and T-shaped limiting plates. The rear end of the outer surface of the rod is threaded with a limit cylinder, and the front end of the limit screw is threaded with a limit cap. The rear surfaces of the cross limit plate and the T-shaped limit plate are provided with symmetrically distributed L-shaped rubber strips. The rear L-shaped rubber strips are all in contact with the front surface of the adjacent glass curtain wall panel, and the front L-shaped rubber strips are all in contact with the front surface of the adjacent photovoltaic curtain wall panel. The output end of the photovoltaic curtain wall panel is electrically connected to the input end of the external photovoltaic controller to achieve stable installation of the glass curtain wall panel and the photovoltaic curtain wall panel.

[0012] Furthermore, both the cross-shaped limiting plate and the T-shaped limiting plate are provided with evenly distributed positioning holes inside.

The fixed screw and the rotatable internal threaded cylinder work together to adjust the spacing between adjacent cross support frames and adjacent T-shaped support frames, so as to achieve rapid and stable adjustment of the thickness of the inner and outer curtain walls and meet the ventilation requirements of different green buildings.

[0017] 2. The connecting blocks are inserted and connected to the connecting posts through the connecting holes inside the connecting handles. At the same time, the connecting handles are limited by the compression of the locking cylinder, enabling quick connection of adjacent cross support frames and T-shaped support frames.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-8 This embodiment provides a technical solution: a green building double-layer curtain wall based on photovoltaic panels, including a cross support frame 1, T-shaped support frames 2 are provided at both ends of the cross support frame 1, glass curtain wall panels 5 are provided between the rear cross support frame 1 and the two rear T-shaped support frames 2, and photovoltaic curtain wall panels 6 are provided between the front cross support frame 1 and the two front T-shaped support frames 2. The photovoltaic curtain wall panels 6 convert solar energy into electrical energy with the assistance of an external photovoltaic controller to provide clean electricity for the building. The outer layer is the photovoltaic curtain wall panel 6, the inner layer is the glass curtain wall panel, and an air layer is formed in the middle. Heat exchange is achieved through natural ventilation or mechanical ventilation. It also includes an adjustment mechanism 3 and a connection mechanism 4.

[0029] Adjustment mechanism 3 includes a screw 31, an internal threaded cylinder 32, a guide rod 33, and a guide tube 34. The screw 31 is fixedly connected to the center of the front surface of the rear cross support frame 1 and the two rear T-shaped support frames 2. The internal threaded cylinder 32 is rotatably connected to the center of the rear surface of the front cross support frame 1 and the two front T-shaped support frames 2. The interior of the internal threaded cylinder 32 is threadedly connected to the adjacent screw 31. The guide rod 33 is evenly fixedly connected to the front surface of the rear cross support frame 1 and the two rear T-shaped support frames 2. The guide tube 34 is evenly fixedly connected to the rear surface of the front cross support frame 1 and the two front T-shaped support frames 2. The outer surface of the guide rod 33 is evenly fixedly connected to the center of the rear surface of the front cross support frame 1 and the two front T-shaped support frames 2. The internal threaded cylinder 32 is slidably connected to the adjacent guide cylinder 34. According to the ventilation requirements of green building, the internal threaded cylinder 32 is rotated. The internal threaded cylinder 32 moves backward under the action of the adjacent fixed screw 31. At the same time, the guide rods 33 slide inside the corresponding guide cylinder 34, providing limiting and guiding functions for the adjacent cross support frame 1 or T-shaped support frame 2. The movement of the internal threaded cylinder 32 drives the adjacent cross support frame 1 or T-shaped support frame 2 to move, thereby realizing the adjustment of the distance between the two longitudinally adjacent cross support frames 1 or T-shaped support frames 2. With the assistance of the external distance measuring tool, when the distance between the two longitudinally adjacent cross support frames 1 or T-shaped support frames 2 reaches the specified value, the rotation of the internal threaded cylinder 32 is stopped.

[0030] Connecting mechanism 4: It is disposed between the cross support frame 1 and the adjacent T-shaped support frame 2. The connecting mechanism 4 includes a connecting groove 41, a connecting block 42, a fixing rod 43, a connecting handle 44, and a connecting post 45. The connecting grooves 41 are evenly disposed inside the cross support frame 1 and the T-shaped support frame 2. A connecting block 42 is inserted between two horizontally adjacent connecting grooves 41. A fixing rod 43 is fixedly connected to the center of the rear surface of the connecting block 42. The outer surface of the fixing rod 43 is slidably connected to the sliding opening inside the adjacent connecting handle 44. Connecting holes are provided at both ends of the connecting handle 44. Evenly distributed connecting posts 45 are fixedly connected to the rear surface of the cross support frame 1 and the T-shaped support frame 2. The connecting holes are fitted with the longitudinally adjacent connecting posts 45. The connecting mechanism 4 also includes a locking cylinder 46. The locking cylinder 46 is sleeved on the outer surface of the adjacent fixing rod 43. The rear end of the outer surface of the 3 are provided with external threads, and the interior of the locking cylinder 46 is provided with internal threads. The internal threads are engaged with the adjacent external threads. The rear end of the locking cylinder 46 is installed in conjunction with the sliding mouth inside the adjacent connecting handle 44. The connecting block 42 is inserted between the two adjacent connecting grooves 41, and then the locking cylinder 46 is rotated. Because the internal thread inside the locking cylinder 46 is engaged with the external thread on the outer surface of the adjacent fixing rod 43, the locking cylinder 46 moves forward. The forward movement of the locking cylinder 46 pushes the adjacent connecting handle 44 to slide forward on the outer surface of the fixing rod 43. The forward movement of the connecting handle 44 causes the connecting post 45 to slide into the corresponding connecting hole. The locking cylinder 46 and the connecting block 42 achieve clamping and limiting of the connecting handle 44. At the same time, the front end of the locking cylinder 46 is inserted into the sliding mouth of the connecting handle 44, thereby achieving a stable connection between the cross support frame 1 and the adjacent T-shaped support frame 2.

[0031] The cross support frame 1 is equipped with a cross limiting plate 7 at its front end, and the T-shaped support frame 2 is equipped with a T-shaped limiting plate 8 at its front end. Both the cross limiting plate 7 and the T-shaped limiting plate 8 have through holes at their center positions. Screws 31 pass through the through holes in the rear cross limiting plate 7 and the T-shaped limiting plate 8. Limiting screws 11 are fixedly connected to the center positions of the front surfaces of the front cross support frame 1 and the two front T-shaped support frames 2. The limiting screws 11 pass through the through holes in the front cross limiting plate 7 and the T-shaped limiting plate 8. A limiting sleeve 13 is threaded to the rear end of the outer surface of the screw 31, and a limiting cap 12 is threaded to the front end of the limiting screw 11. Symmetrically distributed L-shaped rubber strips 16 are provided on the rear surfaces of both the cross limiting plate 7 and the T-shaped limiting plate 8. The L-shaped rubber strips 16 on the rear side are all in contact with the front surface of the adjacent glass curtain wall panel 5, and the L-shaped rubber strips 16 on the front side are all in contact with the front surface of the adjacent photovoltaic curtain wall panel 6. The L-shaped rubber strips 16 are all in contact with the glass curtain wall panel 5 and the photovoltaic curtain wall panel 6 to avoid hard contact damage to the glass curtain wall panel 5 and the photovoltaic curtain wall panel 6. The output end of the photovoltaic curtain wall panel 6 is electrically connected to the input end of the external photovoltaic controller. The interior of the cross limit plate 7 and the T-shaped limit plate 8 is provided with evenly distributed positioning holes 9. The positioning holes 9 inside the rear cross limit plate 7 and the T-shaped limit plate 8 are all slidably connected to the outer surface of the adjacent guide rod 33. The front surface of the front cross support frame 1 and the two front T-shaped support frames 2 are all fixedly connected with evenly distributed positioning posts 10. The positioning holes 9 inside the cross-shaped limiting plate 7 and the T-shaped limiting plate 8 are slidably connected to the outer surface of the adjacent positioning column 10. The glass curtain wall panel 5 is inserted from top to bottom or from bottom to top between the rear cross support frame 1 and the two adjacent T-shaped support frames 2. Then, the limiting cylinder 13 is rotated. The limiting cylinder 13 moves backward under the action of the adjacent fixed screw 31. The backward movement of the limiting cylinder 13 pushes the adjacent cross-shaped limiting plate 7 or T-shaped limiting plate 8 backward. The guide rod 33 provides guidance and limiting function for the backward movement of the corresponding rear cross-shaped limiting plate 7 and T-shaped limiting plate 8. The cross-shaped limiting plate 7 supports the longitudinally adjacent cross support frame 1, and the T-shaped limiting plate 8 supports the longitudinally adjacent T-shaped support frame 2, realizing the stable clamping and limiting of the glass curtain wall panel 5. The photovoltaic curtain wall panel 6 is then inserted from top to bottom or bottom to top between the front cross support frame 1 and the two adjacent T-shaped support frames 2. The limiting cap 12 is then rotated, and the limiting cap 12 moves backward under the action of the adjacent fixed limiting screw 11. The backward movement of the limiting cap 12 pushes the adjacent cross limiting plate 7 or T-shaped limiting plate 8 to move backward. The limiting column 10 provides guidance and limiting function for the backward movement of the corresponding front cross limiting plate 7 and T-shaped limiting plate 8. The cross limiting plate 7 supports the longitudinally adjacent cross support frame 1, and the T-shaped limiting plate 8 supports the longitudinally adjacent T-shaped support frame 2, thereby achieving stable clamping and limiting of the photovoltaic curtain wall panel 6, and thus achieving stable installation of the photovoltaic curtain wall panel 6.

[0032] Wherein: the front surface of the limiting cylinder 13 and the rear surface of the adjacent internal thread cylinder 32 are both provided with bellows 14. The bellows 14 are all sleeved on the outer surface of the adjacent screw 31. The rear end of the bellows 14 is rotatably connected to the front end of the limiting cylinder 13 through a rotating ring. The front end of the bellows 14 is rotatably connected to the rear end of the internal thread cylinder 32 through a rotating ring. This does not affect the rotation of the limiting cylinder 13 and the internal thread cylinder 32. The bellows 14 achieves sealing protection for the screw 31.

[0033] It also includes a mounting base 15, which is fixedly connected to the center of the rear surface of the cross support frame 1 and the two T-shaped support frames 2 on the rear side. The rear end of the mounting base 15 is provided with evenly distributed mounting holes.

[0034] The working principle of the photovoltaic-based double-layer curtain wall for green buildings provided by this utility model is as follows: During operation, personnel first rotate the inner threaded cylinder 32 according to the ventilation requirements of the green building. The inner threaded cylinder 32 moves backward under the action of the adjacent fixed screws 31. At the same time, the guide rods 33 slide inside the corresponding guide cylinders 34, providing limiting and guiding functions for the adjacent cross support frame 1 or T-shaped support frame 2. The movement of the inner threaded cylinder 32 drives the adjacent cross support frame 1 or T-shaped support frame 2 to move, thereby realizing the adjustment of the distance between two longitudinally adjacent cross support frames 1 or T-shaped support frames 2. With the assistance of an external distance measuring tool, when the distance between two longitudinally adjacent cross support frames 1 or T-shaped support frames 2 reaches the specified value, personnel stop. The internal threaded cylinder 32 is stopped from rotating. Then, the connecting blocks 42 are inserted between two adjacent connecting slots 41. Then, the locking cylinder 46 is rotated. Because the internal thread inside the locking cylinder 46 engages with the external thread on the outer surface of the adjacent fixing rod 43, the locking cylinder 46 moves forward. The forward movement of the locking cylinder 46 pushes the adjacent connecting handle 44 to slide forward on the outer surface of the fixing rod 43. The forward movement of the connecting handle 44 causes the connecting post 45 to slide into the corresponding connecting hole. The locking cylinder 46 and the connecting block 42 achieve clamping and limiting of the connecting handle 44. At the same time, the front end of the locking cylinder 46 is inserted into the sliding mouth of the connecting handle 44, thereby achieving a stable connection between the cross support frame 1 and the adjacent T-shaped support frame 2. Then, the mounting hole inside the mounting base 15 is connected to the thread in the working area by bolts. The holes are stably connected, thus achieving stable installation of the cross support frame 1 and the T-shaped support frame 2. Then, personnel insert the glass curtain wall panel 5 from top to bottom or bottom to top between the rear cross support frame 1 and the two adjacent T-shaped support frames 2. Next, personnel rotate the limiting cylinder 13, which moves backward under the action of the adjacent fixed screws 31. The backward movement of the limiting cylinder 13 pushes the adjacent cross limiting plate 7 or T-shaped limiting plate 8 backward. The guide rod 33 provides guidance and limitation for the backward movement of the corresponding rear cross limiting plate 7 and T-shaped limiting plate 8. The cross limiting plate 7 supports the longitudinally adjacent cross support frame 1, and the T-shaped limiting plate 8 supports the longitudinally adjacent T-shaped support frame 2, achieving stable clamping and limiting of the glass curtain wall panel 5. To achieve stable installation of the glass curtain wall panel 5, personnel insert the photovoltaic curtain wall panel 6 from top to bottom or bottom to top between the front cross support frame 1 and the two adjacent T-shaped support frames 2. Then, personnel rotate the limiting cap 12, which moves backward under the action of the adjacent fixed limiting screws 11. This backward movement of the limiting cap 12 pushes the adjacent cross limiting plate 7 or T-shaped limiting plate 8 backward. The limiting posts 10 provide guidance and limitation for the backward movement of the corresponding front cross limiting plate 7 and T-shaped limiting plate 8. The cross limiting plate 7 supports the longitudinally adjacent cross support frame 1, and the T-shaped limiting plate 8 supports the longitudinally adjacent T-shaped support frame 2, achieving stable clamping and limiting of the photovoltaic curtain wall panel 6, thus achieving stable installation of the photovoltaic curtain wall panel 6.This enables the overall installation of a double-layered curtain wall for green buildings based on photovoltaic panels. With the assistance of an external photovoltaic controller, the photovoltaic curtain wall panel 6 converts solar energy into electrical energy, providing clean electricity for the building. The outer layer is the photovoltaic curtain wall panel 6, and the inner layer is a glass curtain wall panel, forming an air layer in between. Heat exchange is achieved through natural or mechanical ventilation.
