Description

Technical Field

[0001] This invention relates to the field of building curtain wall technology, and in particular to a building curtain wall with ventilation and heat dissipation functions. Background Technology

[0002] Building curtain walls are external enclosure structures that do not bear the load of the main structure, and consist of two parts: "panels" and "supporting structures".

[0003] Panels: These are in direct contact with the external environment and serve functions such as lighting, decoration, and protection (e.g., glass, stone, metal panels, etc.).

[0004] Supporting structure: Composed of keel (aluminum alloy, steel, aluminum-wood composite, etc.) and connectors, it transfers the panel load to the main building structure while adapting to building settlement, temperature deformation, etc. Its essence is an "independent system of building skin", which is different from traditional walls (load-bearing + enclosure combined) and windows (relying on partial openings in the wall).

[0005] While existing building curtain walls offer ventilation, they are constantly exposed to the external environment, with the outer facade subjected to wind, rain, and sun, leading to the accumulation of dust and other deposits. This is especially true for high-rise buildings where the curtain walls are enclosed, making exterior cleaning difficult. Cleaning requires workers to perform the task at height, which is unsafe and yields limited results. Furthermore, it prevents indoor cleaning of the exterior facade under adequate ventilation conditions. Therefore, there is an urgent need for a building curtain wall system that combines ventilation and heat dissipation with easy cleaning of the exterior facade. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides the following technical solution:

[0007] A building curtain wall with ventilation and heat dissipation functions includes a frame and a curtain wall body. A first fixing plate is fixedly connected to the top surface of the inner wall of the frame, and a second fixing plate is fixedly connected to the bottom surface. The frame, the first fixing plate, and the second fixing plate form a sealed ventilation space for installing the curtain wall body. The curtain wall body is detachably disposed between the first fixing plate and the second fixing plate. A power mechanism for driving the curtain wall body to rotate back and forth is provided on the top surface of the second fixing plate. A telescopic first positioning mechanism for securing the bottom surface of the curtain wall body is provided on both sides of the top surface of the power mechanism. A telescopic second positioning mechanism for securing the top surface of the curtain wall body is provided on both sides of the bottom surface of the first fixing plate. The curtain wall body is rotatably disposed between the first fixing plate and the second fixing plate at its axis. A support mechanism is provided between the bottom surface of the first fixing plate and the axis of the top surface of the curtain wall body. The support mechanism is slidably connected to the first fixing plate and detachably rotatably connected to the curtain wall body.

[0008] As an improvement to the above technical solution, the power mechanism includes a rotating plate, a first gear and a second gear. The rotating plate has a semi-circular cross-section. One end of the rotating plate is fixedly connected to the first gear. The first gear and the second gear are meshed together. A guide groove is provided in the frame for the first gear and the second gear to rotate. One side of the guide groove passes through the frame, and the second gear protrudes outside the frame.

[0009] As an improvement to the above technical solution, a blocking mechanism is slidably provided on the frame to block the rotation of the second gear. The blocking mechanism includes a slider, a first spring, and a limiting stop plate. A third slide groove is provided on the frame for the slider to slide up and down. The first spring is fixedly disposed between the inner wall of the third slide groove and the slider. The slider is fixedly connected to the limiting stop plate. The bottom of the limiting stop plate is inserted between the teeth of the second gear. The bottom of the limiting stop plate near the surface of the third slide groove has an arc-shaped structure.

[0010] As an improvement to the above technical solution, the first positioning mechanism includes a pressure plate, a second insert, a fourth spring, a threaded rod, and a threaded sleeve. Both sides of the rotating plate are provided with fifth sliding grooves for the pressure plate to slide. The pressure plate has a convex structure. The top surface of the pressure plate is fixedly connected to the second insert, which slides out of the rotating plate. The fourth spring is fixedly connected between the pressure plate and the fifth sliding groove. The top surface of the pressure plate is fixedly connected to the threaded rod, and the outer periphery of the threaded rod is threadedly connected to the threaded sleeve. The threaded sleeve is rotatably connected to the rotating plate, and the top surface of the threaded sleeve and the top surface of the rotating plate are on the same horizontal plane.

[0011] As an improvement to the above technical solution, a rotating rod is rotatably connected at the center of the top surface of the rotating plate, and a first insert is fixedly connected to the top of the rotating rod. A first slot is provided on the bottom surface of the curtain wall body and is sleeved around the first insert. The first slot is slidably sleeved around the second insert.

[0012] As an improvement to the above technical solution, the second positioning mechanism includes a sliding plate, a limiting rod, a limiting insert plate, and a second spring. The first fixed plate has T-shaped limiting grooves on both sides, penetrating the bottom surface of the first fixed plate. The limiting insert plate is slidably disposed within the first limiting grooves, with its bottom end protruding outside the first fixed plate. The top surface of the curtain wall body has second slots on both sides, fitted around the limiting insert plates. The second spring is fixedly connected between the limiting insert plate and the inner wall of the first limiting groove. The front of the limiting insert plate is fixedly connected to the sliding plate. The first fixed plate has a second sliding groove for the sliding plate to slide up and down, communicating with the first limiting groove. The limiting rod is slidably disposed on the front of the sliding plate, with one end penetrating the first fixed plate. The front of the sliding plate has a fourth sliding groove for the limiting rod to slide. The front of the first fixed plate has an L-shaped positioning groove for the limiting rod to slide, communicating with the second sliding groove.

[0013] As an improvement to the above technical solution, the bottom surface of the first fixing plate is provided with a groove corresponding to the top axis of the curtain wall body. The support mechanism includes a sliding component and a positioning component. The sliding component includes a connecting rod and a limiting slide rod. The bottom of the groove is provided with a first sliding groove for the limiting slide rod to slide on both sides. The limiting slide rod is rotatably connected to the connecting rod through a ball bearing. The adjacent connecting rods are rotatably connected to the positioning component through a lifting lug.

[0014] As an improvement to the above technical solution, the positioning component includes a bearing, a moving block, a limiting block, and a third spring. The top surface of the curtain wall body has an installation hole for fixing the outer ring of the bearing. Both sides of the moving block are rotatably connected to the adjacent connecting rods through lifting lugs. The limiting block is slidably disposed inside the moving block, and the bottom end of the limiting block penetrates the moving block and is inserted into the inner wall of the bearing inner ring. The third spring is fixedly connected between the top of the limiting block and the inner wall of the moving block.

[0015] As an improvement to the above technical solution, a rubber sealing frame is fixedly connected to the back of the curtain wall body near the edge.

[0016] The beneficial effects of this invention are:

[0017] The first and second positioning mechanisms securely seal the curtain wall within the ventilated space, ensuring stability when ventilation is not required. The power mechanism allows the curtain wall to be tilted, creating a ventilation opening between the top surface and the frame for heat dissipation. The support mechanism allows the curtain wall to rotate between the tilted mechanism and the second fixing plate, facilitating cleaning of its exterior. This eliminates the need for workers to use ropes to clean the exterior, improving safety. The mechanism also allows for cleaning from inside the room, enhancing both ventilation and cleaning efficiency. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0034] Please refer to Figures 1-14 As shown, the present invention provides a building curtain wall with ventilation and heat dissipation function, including a frame 1 and a curtain wall body 2. A first fixing plate 11 is fixedly connected to the top surface of the inner wall of the frame 1, and a second fixing plate 12 is fixedly connected to the bottom surface. The frame 1, the first fixing plate 11 and the second fixing plate 12 form a sealed ventilation space for installing the curtain wall body 2.

[0035] The curtain wall body 2 is detachably installed between the first fixing plate 11 and the second fixing plate 12. The top surface of the second fixing plate 12 is provided with a power mechanism that drives the curtain wall body 2 to rotate back and forth. Both sides of the top surface of the power mechanism are provided with a telescopic first positioning mechanism that secures the bottom surface of the curtain wall body 2.

[0036] Both sides of the bottom surface of the first fixing plate 11 are provided with a telescopic locking second positioning mechanism for the top surface of the curtain wall body 2.

[0037] The curtain wall body 2 is rotatably mounted between the first fixing plate 11 and the second fixing plate 12 at the axis of the curtain wall body 2. A support mechanism is provided between the bottom surface of the first fixing plate 11 and the top surface of the curtain wall body 2 at the axis of the first fixing plate 11. The support mechanism is slidably connected to the first fixing plate 11 and is detachably rotatably connected to the curtain wall body 2.

[0038] In this case, the curtain wall body 2 is detachably installed between the first fixing plate 11 and the second fixing plate 12, and the curtain wall body 2 is sealed and installed in the ventilation space. A power mechanism for driving the curtain wall body 2 to rotate back and forth is provided on the second fixing plate 12. At the same time, a first positioning mechanism for telescopically securing the curtain wall body 2 is provided on the power mechanism, and a second positioning mechanism for telescopically securing the curtain wall body 2 is provided on the bottom surface of the first fixing plate 11. Therefore, when installing the curtain wall body 2, the direction of the top surface of the power mechanism is adjusted by rotating the power mechanism, and then the curtain wall body 2 is secured to the first positioning mechanism. Then, the support mechanism is inserted into the top surface axis of the curtain wall body 2 to limit the curtain wall body 2. At this time, the curtain wall body 2 is in an inclined state. Then, by adjusting the power mechanism, the curtain wall body 2 can be rotated and moved towards the ventilation space, and the curtain wall body 2 is sealed and installed in the ventilation space. At this time, the second positioning mechanism can be inserted into the top surface of the curtain wall body 2 to limit the curtain wall body 2 and prevent the curtain wall body 2 from shaking.

[0039] When ventilation and heat dissipation are required, the second positioning mechanism can be adjusted to release its restriction on the curtain wall body 2. At this time, the power mechanism can drive the curtain wall body 2 to rotate towards the interior, making the curtain wall body 2 tilted to facilitate ventilation and heat dissipation. In this state, the first positioning mechanism is locked in place. Under the limiting action of the support mechanism and the first positioning mechanism, the tilted state of the curtain wall body 2 can be guaranteed, preventing rotation and ensuring that the curtain wall body 2 is always in a state of ventilation and heat dissipation.

[0040] When it is necessary to clean the outer surface of the curtain wall body 2, the first positioning mechanism is adjusted while the curtain wall body 2 is tilted, releasing the first positioning mechanism's limitation on the curtain wall body 2. At this time, the curtain wall body 2 is rotatably positioned between the first fixed plate 11 and the support mechanism at its axis. By rotating the curtain wall body 2, the curtain wall body 2 can be rotated along its axis, adjusting the direction of the curtain wall body 2, making it easier to adjust the curtain wall body 2 to a state perpendicular to the frame 1. This facilitates cleaning the outer surface of the curtain wall body 2, ensuring the cleanliness of the outer surface of the curtain wall body 2.

[0041] The first and second positioning mechanisms securely seal the curtain wall body 2 within the ventilation space, ensuring its stability when ventilation is not required. The power mechanism allows the curtain wall body 2 to be adjusted to an inclined position, creating a ventilation opening between the top surface of the curtain wall body 2 and the frame 1 for ventilation and heat dissipation. The support mechanism allows the curtain wall body 2 to rotate between the support mechanism and the second fixing plate 12 while tilted, facilitating cleaning of its outer surface and eliminating the need for workers to use ropes to clean it from the outside, thus improving safety. The mechanism also allows for easy cleaning of the curtain wall body 2 from inside the room, improving efficiency while simultaneously promoting ventilation and heat dissipation.

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 11 As shown, the power mechanism includes a rotating plate 5, a first gear 52, and a second gear 521. The rotating plate 5 has a semi-circular cross-section. One end of the rotating plate 5 is fixedly connected to the first gear 52. The first gear 52 and the second gear 521 are meshed together. A guide groove 13 is provided in the frame 1 for the first gear 52 and the second gear 521 to rotate. One side of the guide groove 13 passes through the frame 1, and the second gear 521 protrudes out of the frame 1.

[0043] A blocking mechanism is slidably provided on the frame 1 to prevent the second gear 521 from rotating. The blocking mechanism includes a slider 15, a first spring 151, and a limiting plate 152. A third slide groove 14 is provided on the frame 1 for the slider 15 to slide up and down. The first spring 151 is fixedly disposed between the inner wall of the third slide groove 14 and the slider 15. The slider 15 is fixedly connected to the limiting plate 152. The bottom of the limiting plate 152 is inserted between the teeth of the second gear 521. The bottom of the limiting plate 152 near the surface of the third slide groove 14 has an arc-shaped structure.

[0044] The second gear 521 protrudes from the frame 1 to facilitate its rotation. Rotating the second gear 521 drives the first gear 52 to rotate, which in turn drives the rotating plate 5 to rotate. The rotating plate 5 then drives the curtain wall body 2 to rotate around the rotating plate 5 as its axis, causing the curtain wall body 2 to tilt. This facilitates opening the curtain wall body 2 for ventilation and heat dissipation. During the rotation of the second gear 521, since one side of the limiting baffle 152 is arc-shaped, when the teeth of the second gear 521 touch the limiting baffle 152, the first spring 151 causes the limiting baffle 152 to move upward, allowing the teeth of the second gear 521 to pass through the limiting baffle 152. After one tooth passes through the limiting baffle 152, the other side of the limiting baffle 152, which is not arc-shaped, blocks the tooth, preventing the second gear 521 from rotating back. This prevents the curtain wall body 2 from closing due to wind, ensuring continuous ventilation and heat dissipation.

[0045] Among them, such as Figure 2 and Figure 3 The diagram shows the structure of the limiting baffle 152. The limiting baffle 152 is provided with a toothed anti-slip block to facilitate the movement of the limiting baffle 152. When ventilation is not required, the limiting baffle 152 is pushed upward to disengage it from the second gear 521. At this time, the curtain wall body 2 can be sealed into the ventilation space by rotating the second gear 521.

[0046] like Figure 5 , Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, the first positioning mechanism includes a pressure plate 6, a second insert 61, a fourth spring 62, a threaded rod 63, and a threaded sleeve 631. Both sides of the rotating plate 5 are provided with fifth sliding grooves 51 for the pressure plate 6 to slide. The pressure plate 6 has a convex structure. The top surface of the pressure plate 6 is fixedly connected to the second insert 61. The second insert 61 slides out of the rotating plate 5. The fourth spring 62 is fixedly connected between the pressure plate 6 and the fifth sliding groove 51. The top surface of the pressure plate 6 is fixedly connected to the threaded rod 63. The outer periphery of the threaded rod 63 is threadedly connected to the threaded sleeve 631. The threaded sleeve 631 is rotatably connected to the rotating plate 5. The top surface of the threaded sleeve 631 and the top surface of the rotating plate 5 are on the same horizontal plane.

[0047] A rotating rod 53 is rotatably connected at the center of the top surface of the rotating plate 5. A first insert 531 is fixedly connected to the top of the rotating rod 53. A first slot 21 is provided on the bottom surface of the curtain wall body 2 and is sleeved around the first insert 531. The first slot 21 is slidably sleeved around the second insert 61.

[0048] With the first insert 531 and the second insert 61 in place, when the curtain wall body 2 needs to be installed, the first slot 21 opened on the bottom surface of the curtain wall body 2 is fitted around the first insert 531 and the second insert 61 to fix the bottom surface of the curtain wall body 2. After the installation of the curtain wall body 2 is completed, when it is necessary to clean the outer surface of the curtain wall body 2, the curtain wall body 2 is adjusted to an inclined state, as shown below. Figure 12 The diagram illustrates the structure of the threaded sleeve 631. Its top surface is on the same horizontal plane as the rotating plate 5, ensuring unobstructed rotation of the curtain wall body 2. A screwdriver insertion hole is provided on the top surface of the threaded sleeve 631, allowing easy rotation using a screwdriver commonly used in the prior art. The rotation of the threaded sleeve 631 drives the threaded rod 63 to move, which in turn causes the pressure plate 6 to slide within the fifth groove 51 and press the fourth spring 62. The fourth spring 62 supports the pressure plate 6, which in turn drives the second insert 61 to move, disengaging it from the first slot 21. This facilitates rotation of the curtain wall body 2, changing its orientation and enabling cleaning of the outer surface of the curtain wall body 2 to ensure its cleanliness.

[0049] Additional explanation: During the installation of the curtain wall body 2, firstly rotate the rotating plate 5 to move the first insert 531 and the second insert 61 accordingly. Then, fit the first slot 21 on the bottom surface of the curtain wall body 2 around the first insert 531 and the second insert 61. Then, insert the support mechanism into the center of the top surface of the curtain wall body 2 to make the curtain wall body 2 tilted. Then, by rotating the rotating plate 5, the curtain wall body 2 can be sealed and installed in the ventilation space, which facilitates the installation of the curtain wall body 2.

[0050] like Figure 5 , Figure 9 and Figure 10 As shown, the second positioning mechanism includes a sliding plate 3, a limiting rod 311, a limiting insert 32, and a second spring 321. Both sides of the first fixed plate 11 have first limiting grooves 113 with a T-shaped structure penetrating the bottom surface of the first fixed plate 11. The limiting insert 32 is slidably disposed within the first limiting groove 113, with its bottom end protruding outside the first fixed plate 11. Both sides of the top surface of the curtain wall body 2 have second slots 23 that are fitted around the limiting insert 32. The second spring 321 is fixedly connected between the limiting insert 32 and the inner wall of the first limiting groove 113. The front of the insertion plate 32 is fixedly connected to the slide plate 3. The first fixing plate 11 has a second sliding groove 114 for the slide plate 3 to slide up and down. The second sliding groove 114 communicates with the first limiting groove 113. The limiting rod 311 is slidably disposed on the front of the slide plate 3, and one end of the limiting rod 311 passes through the first fixing plate 11. The front of the slide plate 3 has a fourth sliding groove 31 for the limiting rod 311 to slide. The front of the first fixing plate 11 has an L-shaped positioning groove 115 for the limiting rod 311 to slide. The positioning groove 115 communicates with the second sliding groove 114.

[0051] With the setting of the limiting plate 32, after the curtain wall body 2 is installed in the ventilation space, the limiting plate 32 can be inserted into the second slot 23 opened on the top surface of the curtain wall body 2 to fix the curtain wall body 2 as a whole and ensure its stability, so as to prevent it from moving during the wind when ventilation is not needed. When ventilation is needed, the limiting rod 311 can be pushed to drive the sliding plate 3 to move. The sliding plate 3 drives the limiting plate 32 to move. The limiting plate 32 presses the second spring 321, so that the limiting plate 32 is released from the limiting of the curtain wall body 2. Then the limiting rod 311 is slid to position the limiting rod 311 in the positioning groove 115.

[0052] like Figure 5 , Figure 7 , Figure 8 and Figure 9 As shown, the bottom surface of the first fixing plate 11 is provided with a groove 111 at the axis of the top surface of the curtain wall body 2. The support mechanism includes a sliding component and a positioning component. The sliding component includes a connecting rod 41 and a limiting slide rod 411. The bottom of the groove 111 is provided with a first sliding groove 112 for the limiting slide rod 411 to slide. The limiting slide rod 411 is rotatably connected to the connecting rod 41 through a ball bearing. The adjacent connecting rods 41 are rotatably connected to the positioning component through a lifting lug.

[0053] The positioning components include a bearing 221, a movable block 4, a limiting insert 42, and a third spring 43. A mounting hole 22 for fixing the outer ring of the bearing 221 is provided at the center of the top surface of the curtain wall body 2. Both sides of the movable block 4 are rotatably connected to the adjacent connecting rods 41 through lifting lugs. The limiting insert 42 is slidably disposed in the movable block 4, and the bottom end of the limiting insert 42 penetrates the movable block 4 and is inserted into the inner wall of the inner ring of the bearing 221. The third spring 43 is fixedly connected between the top of the limiting insert 42 and the inner wall of the movable block 4.

[0054] With the setting of the limiting plug 42, during the installation of the curtain wall body 2, after the bottom surface of the curtain wall body 2 is fixed, the moving block 4 is moved by pulling, and then the limiting plug 42 is inserted into the inner ring of the bearing 221 to position the top surface of the curtain wall body 2. When the moving block 4 is pulled, the connecting rod 41 can be moved, and the connecting rod 41 pulls the limiting slide rod 411 to slide. Since the connecting rod 41 and the limiting slide rod 411 are connected by ball bearings, the connecting rod 41 can easily adapt to different positions when the curtain wall body 2 is in an inclined state.

[0055] During the process of sealing the curtain wall body 2 in the ventilation space, the curtain wall body 2 drives the bearing 221 to move, the bearing 221 drives the limit block 42 and the moving block 4 to move, the moving block 4 drives the connecting rod 41 to move, and the connecting rod 41 pushes the limit slide rod 411 to slide.

[0056] Among them, when the curtain wall body 2 is in an inclined state, the connecting rod 41 has a supporting function.

[0057] Additional explanation: By adopting a ball bearing connection, the connecting rod 41 can easily adapt to the arc-shaped movement. When ventilation is required, the top of the curtain wall body 2 is rotated, which will cause the connecting rod 41 to move in a small arc. Although a ball bearing connection is used, the rolling range of the ball bearing is small, and the limiting block 42 will not be disengaged from the inner ring of the bearing 221 when in a ventilated state.

[0058] like Figure 4 As shown, a rubber sealing frame 24 is fixedly connected to the back of the curtain wall body 2 near the edge.

[0059] The rubber sealing frame 24 can further increase the sealing performance of the curtain wall body 2 after it is installed in the ventilation space, so that the rubber sealing frame 24 fits against the inner wall of the frame 1 and improves the sealing performance.

[0060] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
