Description

Technical Field

[0001] The present application relates to the field of building curtain walls, and in particular to a cantilevered aluminum panel curtain wall structure. Background Art

[0002] At present, aluminum curtain walls are widely used in engineering projects for the decoration of building facades, especially in large cantilever decorative lines, due to their rich shapes and colorful color combinations.

[0003] Its structure primarily consists of embedded panels, faceplates, reinforcing ribs, and angle brackets. The embedded panels are bolted to the structure for load-bearing. The angle brackets can be bent or stamped directly from the faceplates, or riveted onto the small edges of the faceplates. The reinforcing ribs are connected to the back of the panels with welded screws (the screws are welded directly to the back of the panels), forming a solid, integrated structure. This significantly enhances the strength and rigidity of the aluminum veneer curtain wall, ensuring its smoothness, wind resistance, and earthquake resistance over long-term use. If sound insulation or thermal insulation is required, high-efficiency soundproofing and thermal insulation materials can be installed inside the aluminum panels.

[0004] In related technology, Chinese patent application number CN214402340U discloses an internal drainage node and curtain wall structure for a cantilevered aluminum curtain wall. The node comprises an inner panel assembly, comprising an upper panel and a lower panel arranged vertically, and an inner panel connecting the upper and lower panels. The upper panel is provided with a drainage slope, the lower panel is provided with a drip line, and an outer decorative panel is provided on the outer side of the inner panel. Specifically, the outer decorative panel is fixed to the outer side of the inner panel assembly via a hanging assembly. A water-passing gap is reserved between the inner and outer panels, and the drainage slope is connected to the drip line through the water-passing gap, forming an internal drainage structure. When it rains, rainwater flows through the drainage slope and the water-passing gap to the drip line and is discharged.

[0005] When rain falls, it will carry dust floating in the atmosphere into the water gap, making it easy for a large amount of dust to accumulate between the inner panel and the outer panel after the rain, thereby causing blockage between the drip line and the outer panel. That is, rainwater cannot flow out from the drip line, affecting drainage efficiency, so it needs to be improved. Summary of the Invention

[0006] In order to improve the problem that dust easily clogs the space between the drip line and the exterior panel, thereby affecting the drainage rate, the present application provides a cantilevered aluminum panel curtain wall structure.

[0007] The cantilevered aluminum curtain wall structure provided in this application adopts the following technical solution:

[0008] A cantilevered aluminum curtain wall structure, vertically fixed on the wall, comprising:

[0009] The curtain wall body includes an inner panel and an outer panel. The inner panel is vertically fixed on the wall surface. The outer panel is parallel to the inner panel and connected by a connecting plate. The inner panel and the outer panel are vertically connected to form a drainage cavity.

[0010] The filter assembly is connected to the inner plate and is arranged at the opening of the drainage cavity to limit impurities from entering the drainage cavity.

[0011] By adopting the above technical solution, when it rains, rainwater, carrying impurities from the air, falls to the top opening of the drainage chamber. The impurities are blocked outside the drainage chamber by the filter assembly, while the rainwater can smoothly pass through the filter assembly and enter the drainage chamber, and finally be discharged from the bottom opening of the drainage chamber. This prevents excessive accumulation of impurities in the drainage chamber, thereby preventing the inner diameter of the drainage chamber from being reduced, and thus does not affect the drainage efficiency of the curtain wall body. At the same time, most of the rainwater that falls on the curtain wall body is discharged through the drainage chamber, that is, the drainage chamber distributes the rainwater that washes the outer panels, making the outer panels less susceptible to rainwater erosion and extending the service life of the outer panels.

[0012] Optionally, a guide plate is fixed on the top wall of the outer plate, and the guide plate is tilted downward on one side close to the inner plate, and the other side extends away from the inner plate and is tilted downward.

[0013] By adopting the above technical solution, when rainwater falls from top to bottom to the top of the curtain wall body, the rainwater drops on the drainage plate, and the drainage plate plays a guiding role, so that the rainwater moves along the inclined direction of the drainage plate, that is, part of the rainwater flows into the drainage cavity, and part of the rainwater flows along the drainage plate from the side of the outer plate away from the inner plate, reducing the rainwater directly contacting the outer plate, thereby reducing the scouring of the outer plate by rainwater, making the outer plate less susceptible to rainwater erosion and extending the service life of the outer plate.

[0014] Optionally, the filtering component includes:

[0015] an upper filter plate connected to the inner plate and horizontally placed on the top of the drainage cavity, for preventing impurities from entering the drainage cavity through the top opening of the drainage cavity;

[0016] The lower filter plate is connected to the inner plate and is horizontally placed at the bottom of the drainage cavity to prevent impurities from entering the drainage cavity through the bottom opening of the drainage cavity.

[0017] By adopting the above technical solution, the upper filter plate and the lower filter plate cooperate to block all openings connecting the drainage chamber to the outside world, so that impurities in the rainwater cannot pass through the upper filter plate into the drainage chamber. At the same time, the lower filter plate also prevents impurities driven by wind from entering the drainage chamber from the bottom opening of the drainage chamber, so that excessive impurities will not accumulate in the drainage chamber, and the efficiency of rainwater discharge through the drainage chamber will not be affected.

[0018] Optionally, the inner plate is provided with a driving assembly for driving the upper filter plate and the lower filter plate to flip, and the upper filter plate and the lower filter plate are connected to the inner plate through the driving assembly. The driving assembly rotates to drive the upper filter plate and the lower filter plate to move closer to or away from each other.

[0019] By adopting the above technical solution, after long-term use, more impurities will accumulate on the upper surface of the upper filter plate. At this time, the driving component is started to drive the upper filter plate and the lower filter plate to move, so that the upper filter plate and the lower filter plate approach each other, meet and cross each other, and then move away from each other, so that the positions of the upper filter plate and the lower filter plate are swapped, so that the cleaner lower filter plate is located at the top opening of the drainage cavity, that is, it is used as a new upper filter plate, so that the impurities originally accumulated on the upper filter plate will not affect the rate at which rainwater enters the drainage cavity from the top opening of the drainage cavity, thereby improving the drainage efficiency.

[0020] Optionally, the upper filter plate includes a plurality of mounting rods and a plurality of mounting plates, wherein the plurality of mounting rods are parallel to each other and arranged horizontally on the top of the drainage chamber, the plurality of mounting rods are connected to the inner plate through the driving assembly, and each mounting rod is provided with a mounting plate, and the mounting plate is arranged upwardly and tilted on a side away from the mounting rod, and the mounting rod is provided with a mounting torsion spring, and the mounting torsion spring is used to push adjacent mounting plates against each other;

[0021] The lower filter plate includes a plurality of movable plates and a plurality of movable rods staggered with the mounting rods. The plurality of movable rods are parallel to each other and arranged horizontally at the bottom of the drainage chamber. The plurality of movable rods are connected to the inner plate through the driving assembly. Each movable rod is sleeved with a movable plate. The movable plate is tilted downward away from the side of the movable rod. The movable rod is provided with a movable torsion spring. The movable torsion spring is used to push adjacent movable plates against each other. A plurality of filter holes are penetrated by both the mounting plate and the movable plate.

[0022] By adopting the above technical solution, when the driving assembly drives the upper filter plate and the lower filter plate to approach each other until the upper filter plate and the lower filter plate intersect, that is, the bottom wall of the mounting plate abuts the movable rod, and the top wall of the movable plate abuts the mounting rod, the driving assembly continues to move, so that the movable rod pushes the mounting plate to rotate upward with the mounting rod as the axis. The mounting plate is acted upon by the mounting torsion spring to abut against the adjacent mounting plate and slides on the side wall of the adjacent mounting plate, thereby scraping off impurities on the side wall of the mounting plate and achieving cleaning of the mounting plate. At the same time, the mounting rod pushes the movable plate to rotate downward with the moving rod as the axis. The movable plate is acted upon by the moving torsion spring to always abut against the adjacent movable plate and slides on the side wall of the adjacent movable plate, thereby achieving cleaning of the movable plate.

[0023] When the mounting plate rotates to the point where one movable plate can pass between adjacent mounting plates, the movable plate rotates to the point where one mounting plate can pass between adjacent movable plates, causing the movable plate and the mounting plate to separate from each other, that is, the mounting plate loses thrust, and the mounting torsion spring recovers its deformation, causing the adjacent mounting plates to rest against each other again to form a complete upper filter plate. Similarly, when the mounting rod moves to the point where it is separated from the movable plate, the movable plate loses thrust, and the movable torsion spring recovers its deformation, causing the adjacent movable plates to rest against each other again to form a complete lower filter plate. When the upper filter plate moves to the position where the lower filter plate was originally located, the lower filter plate also moves to the top of the drainage chamber, and finally the positions of the upper and lower filter plates can be swapped.

[0024] Optionally, the driving component includes:

[0025] A driving transmission belt is provided on the inner plate, the driving transmission belt includes a driving belt and two driving wheels, the two driving wheels are rotatably connected to the inner plate, and the two driving wheels are arranged in a vertical direction, the driving belt is sleeved on the two driving wheels, and the driving wheels rotate to drive the driving belt to move;

[0026] a first connecting rod, wherein the first connecting rod is horizontally arranged, and one end of the first connecting rod is fixed to one side of the driving belt, and one end of the upper filter plate close to the inner plate is fixed to the first connecting rod;

[0027] The second connecting rod is horizontally arranged, and one end of the second connecting rod is fixed to the other side of the driving belt, and the end of the lower filter plate away from the inner plate is fixed to the first connecting rod.

[0028] By adopting the above technical solution, the driving wheel rotates, driving the driving belt to move, so that the first connecting rod first moves upward to the highest point of the driving transmission belt, and the second connecting rod first moves downward to the lowest point of the driving transmission belt, and then the first connecting rod and the second connecting rod approach each other again, so that the first connecting rod rotates 180° with the central axis of the upper driving wheel as the axis, that is, the upper and lower surfaces of the upper filter plate are reversed, so that the impurities accumulated on the upper filter plate face downward, and the second connecting rod rotates 180° with the central axis of the lower driving wheel as the axis, so that the upper and lower surfaces of the lower filter plate are also reversed.

[0029] When the upper filter plate passes over the lower filter plate and moves to the bottom of the drainage chamber, the lower filter plate also moves to the top of the drainage chamber, becoming the new upper filter plate. When rainwater carries impurities from the air onto the new upper filter plate, it is relatively clean—the filter holes are not clogged by impurities. This allows rainwater to pass smoothly through the new upper filter plate into the drainage chamber and finally out through the filter holes on the lower mounting plate. Because impurities on the mounting plate face downward, they flush impurities from the bottom wall of the mounting plate, thereby cleaning the mounting plate. If the lower filter plate, acting as the upper filter plate, also accumulates a large amount of impurities, the above steps are repeated to clean it, ensuring drainage efficiency is not affected.

[0030] Optionally, an auxiliary transmission belt is provided on the side of the outer plate close to the inner plate, and the auxiliary transmission belt includes an auxiliary belt and two auxiliary wheels. The two auxiliary wheels are rotatably connected to the outer plate, and the auxiliary wheels correspond to the driving wheels. The auxiliary belt is sleeved on the two auxiliary wheels, and the auxiliary wheels rotate to drive the auxiliary belt to move. One side of the auxiliary belt is fixed to the first connecting rod, and the other side is fixed to the second connecting rod. The auxiliary transmission belt rotates synchronously with the driving transmission belt, driving the first connecting rod and the second connecting rod to approach or move away from each other.

[0031] By adopting the above technical solution, when the driving transmission belt drives the first connecting rod and the second connecting rod to move, the auxiliary transmission belt rotates synchronously, and also drives the first connecting rod and the second connecting rod to move, so that both sides of the first connecting rod and the second connecting rod are supported, so that the upper filter plate and the lower filter plate are not prone to tilting and deflection during movement, thereby increasing the stability of the movement of the upper filter plate and the lower filter plate.

[0032] Optionally, a rotating assembly for driving the driving transmission belt and the auxiliary transmission belt to rotate synchronously is provided on the connecting plate, and the rotating assembly includes:

[0033] a rotating gear rotatably connected to the inner plate, wherein the rotating gear is coaxially fixed to one of the driving wheels;

[0034] A rotating rack is slidably connected to the inner plate and meshes with the rotating gear, and the rotating rack moves in a vertical direction;

[0035] a transmission gear rotatably connected to the outer plate, wherein the transmission gear is coaxially fixed to one of the auxiliary wheels;

[0036] A transmission rack is slidably connected to the outer plate and meshes with the transmission gear, and the transmission rack moves in a vertical direction;

[0037] Two linkage gears are rotatably connected to the connecting plate and mesh with each other. The rotating rack and the transmission rack are both vertically fixed with linkage racks. The two linkage gears are located between the two linkage racks, and the linkage wheel meshes with the linkage racks.

[0038] The electric push rod is fixed on the inner plate, and the output end of the electric push rod is fixed to the end of the rotating rack to drive the rotating rack to move in the vertical direction.

[0039] By adopting the above technical solution, when the upper filter plate and the lower filter plate need to be swapped, the electric drive is started to push the rotating rack and the linkage rack fixed to the rotating rack to move in the vertical direction. While driving the rotating gear to rotate, the linkage gear is also driven to rotate. Then, another linkage gear drives the linkage rack connected to the transmission rack and the transmission rack to move, so that the two linkage racks move in the same direction and at the same time, that is, the drive belt and the auxiliary transmission belt rotate synchronously, and at the same time, the two sides of the first connecting rod and the second connecting rod are pulled to move the same distance, so that the upper filter plate and the lower filter plate always maintain a horizontal state and move, and are not easily offset.

[0040] Optionally, a water outlet hole communicating with the drainage cavity is formed through the connecting plate, and the water outlet hole is located at the bottom of the connecting plate.

[0041] By adopting the above technical solution, when the amount of rainwater is large, after the rainwater passes through the upper filter plate and enters the drainage cavity, part of the rainwater is discharged through the water outlet hole, thereby increasing the drainage rate of the drainage cavity.

[0042] Optionally, a drainage cover is fixed on the side wall of the connecting plate away from the drainage chamber, and the drainage cover is located on the side of the water outlet opening. The bottom of the drainage cover is connected to the water outlet, and the drainage cover is used to limit impurities from entering the drainage chamber through the water outlet.

[0043] By adopting the above technical solution, the drainage cover covers the water outlet, so that the rainwater drives the impurities in the air to drip onto the connecting plate, and then flows along the connecting plate to the drainage cover. The drainage cover plays a guiding role, so that the rainwater flows downward along the drainage cover, so that the impurities will not enter the drainage cavity through the water outlet, and impurities are not easily accumulated in the drainage cavity, that is, the drainage rate will not be affected.

[0044] In summary, this application has at least one of the following beneficial effects:

[0045] 1. When it rains, rainwater, carrying impurities in the air, falls to the top opening of the drainage cavity. The impurities are blocked outside the drainage cavity by the filter assembly, while the rainwater can smoothly pass through the filter assembly and enter the drainage cavity, and finally be discharged from the bottom opening of the drainage cavity, so that excessive impurities will not accumulate in the drainage cavity, and the inner diameter of the drainage cavity will not be reduced, that is, it will not affect the drainage efficiency of the curtain wall body. At the same time, most of the rainwater falling on the curtain wall body is discharged through the drainage cavity, that is, the drainage cavity shares the rainwater that washes the outer panel, making the outer panel less susceptible to rainwater erosion and extending the service life of the outer panel;

[0046] 2. When rainwater falls from top to bottom to the top of the curtain wall body, the rainwater drops on the drainage plate. The drainage plate plays a guiding role, so that the rainwater moves along the inclined direction of the drainage plate, that is, part of the rainwater flows into the drainage cavity, and part of the rainwater flows along the drainage plate from the side of the outer plate away from the inner plate, reducing the rainwater that directly contacts the outer plate, thereby reducing the scouring of the outer plate by rainwater, making the outer plate less susceptible to rainwater erosion and extending the service life of the outer plate.

DETAILED DESCRIPTION

[0054] The following is combined with Figure 1-6 This application is described in further detail.

[0055] The embodiment of the present application discloses a cantilevered aluminum curtain wall structure. Figure 1 and Figure 2 The cantilevered aluminum panel curtain wall structure includes a curtain wall body 10, which includes an inner panel 11 and an outer panel 12. The inner panel 11 is vertically fixed to the wall surface by bolts, and the outer panel 12 is parallel to the inner panel 11 and is located on the side of the inner panel 11 away from the wall surface. The side of the outer panel 12 away from the inner panel 11 is provided with a decorative surface. Two connecting plates 20 are provided between the inner panel 11 and the outer panel 12. The connecting plates 20 are located at the ends of the inner panel 11 in the vertical direction, and the connecting plates 20 are C-shaped steel. The two connecting plates 20 are arranged opposite to each other, and the inner panel 11 and the outer panel 12 are fixedly connected to the opposite side walls of the connecting plates 20 by bolts. The inner panel 11, the outer panel 12 and the connecting plates 20 form an internal hollow frame, that is, the inner panel 11 and the outer panel 12 are connected from top to bottom, and a drainage cavity 13 is formed.

[0056] Reference Figure 1When it rains, in order to reduce the amount of rainwater that washes away the decorative surface, a drainage plate 70 is fixed to the top wall of the outer panel 12. The drainage plate 70 is an L-shaped plate with its turning angle facing upward and its two ends tilted downward. The end of the drainage plate 70 away from the inner panel 11 extends out of the top of the outer panel 12 and extends downward to cover the portion of the outer panel 12 away from the inner panel 11. When rainwater falls from top to bottom to the top of the curtain wall body 10, the rainwater drops onto the drainage plate 70. The drainage plate 70 acts as a guide, causing the rainwater to move along the tilt direction of the drainage plate 70. In other words, some rainwater flows into the drainage cavity 13, while some rainwater flows along the drainage plate 70 from the side of the outer panel 12 away from the inner panel 11. This reduces the amount of rainwater that directly contacts the outer panel 12, thereby reducing the amount of rainwater that washes away the outer panel 12, making the decorative surface less susceptible to rainwater erosion and extending the service life of the decorative surface.

[0057] Reference Figure 1 and Figure 2 In order to increase the drainage rate of the drainage chamber 13, a water outlet hole 21 is opened through the connecting plate 20, so that rainwater entering the drainage chamber 13 can also flow out through the water outlet hole 21. A drainage cover 22 is fixed on the side wall of the connecting plate 20 away from the drainage chamber 13. The drainage cover 22 is located on the side of the opening of the water outlet hole 21, and the bottom of the drainage cover 22 is connected to the water outlet hole 21. The drainage cover 22 covers the water outlet hole 21, so that the rainwater drives the impurities in the air to drip onto the connecting plate 20, and then flows along the connecting plate 20 to the drainage cover 22. The drainage cover 22 plays a guiding role, so that the rainwater flows downward along the drainage cover 22, so that impurities will not enter the drainage chamber 13 through the water outlet hole 21. Impurities are not easily accumulated in the drainage chamber 13, that is, the drainage rate will not be affected.

[0058] Reference Figure 2 and Figure 3 When it rains, rainwater falls with impurities in the air. In order to prevent impurities from accumulating in the drainage chamber 13 and blocking the drainage chamber 13, a filter assembly 30 for filtering impurities is provided in the drainage chamber 13. The filter assembly 30 includes an upper filter plate 31 and a lower filter plate 32. The upper filter plate 31 is horizontally arranged at the top opening of the drainage chamber 13, and is used to filter rainwater entering the drainage chamber 13 from the top of the drainage chamber 13. The lower filter plate 32 is horizontally arranged at the bottom opening of the drainage chamber 13, and is used to filter impurities blown by the wind and entering the drainage chamber 13 from the bottom opening of the drainage chamber 13.

[0059] Reference Figure 2 and Figure 3When a large amount of impurities accumulate on the upper surface of the upper filter plate 31, in order to prevent the impurities from affecting the rainwater from passing through the upper filter plate 31 and entering the drainage chamber 13, a driving assembly 40 for driving the upper filter plate 31 and the lower filter plate 32 to move is provided on the milk flap. The driving assembly 40 includes a driving transmission belt 41, a first connecting rod 42 and a second connecting rod 43. The driving transmission belt 41 includes a driving belt 412 and two driving wheels 411. The two driving wheels 411 are distributed vertically up and down and are both embedded in the inner plate 11 and rotatably connected to the inner plate 11. The upper half of the upper driving wheel 411 extends out of the top wall of the inner plate 11, while the lower half of the lower driving wheel 411 extends out of the bottom wall of the inner plate 11. The driving belt 412 is sleeved on the two driving wheels 411, and the two driving wheels 411 rotate to drive the driving belt 412 to move, so that the parts of the driving belt 412 in contact with the driving wheels 411 are exposed outside the inner plate 11.

[0060] Reference Figure 2 and Figure 3 The first connecting rod 42 and the second connecting rod 43 are both horizontally arranged L-shaped rods, with the length of the outer panel 12 being the vertical direction and the width of the outer panel 12 being the horizontal direction. One side of the first connecting rod 42 is equal to the width of the outer panel 12, and the other side is equal to the distance between the outer panel 12 and the inner panel 11. One side of the first connecting rod 42 is secured to the drive belt 412 via a connecting rod. The second connecting rod 43 is centrally symmetrical about the central axis of the drainage chamber 13 and secured to the other side of the drive belt 412 via a connecting rod. Initially, the first connecting rod 42 is located at the top opening of the drainage chamber 13, and the second connecting rod 43 is located at the bottom opening of the drainage chamber 13.

[0061] Reference Figure 3 and Figure 4 The upper filter plate 31 includes a plurality of mounting rods 311 and a plurality of mounting plates. The plurality of mounting rods 311 are evenly arranged along the width direction of the outer plate 12. The ends on the same side of the plurality of mounting rods 311 are fixed to the first connecting rod 42. A mounting plate 312 is sleeved on each mounting rod 311. The mounting plate 312 is tilted upward on the side away from the mounting rod 311. A mounting torsion spring 313 is provided on the mounting rod 311. One end of the mounting torsion spring 313 is fixed to the mounting rod 311, and the other end is fixed to the mounting plate 312, which is used to push adjacent mounting plates 312 against each other, and one mounting plate 312 at the end is against a section of the first connecting rod 42 perpendicular to the width direction of the outer plate 12.

[0062] Reference Figure 3 and Figure 5The unclamping method is to make the unclamping method more vivid and solvable, and the effect of the unclamping method being that clarifies the ingenuity of the lifter 320 is that it is difficult to see the clarification on the clarification result.

[0063] The driving wheel 411 rotates, driving the driving belt 412 to move, so that the first connecting rod 42 first moves upward to the highest point of the driving transmission belt 41, and the second connecting rod 43 first moves downward to the lowest point of the driving transmission belt 41, and then the first connecting rod 42 and the second connecting rod 43 approach each other again. During this process, the first connecting rod 42 moves out of the drainage chamber 13 with the driving belt 412, and above the curtain wall body 10 and rotates 180° with the center axis of the upper driving wheel 411 as the axis to enter the drainage chamber 13. Similarly, the second connecting rod 43 also moves out of the drainage chamber 13 driven by the driving belt 412, and below the curtain wall body 10 and rotates 180° with the center axis of the lower driving wheel 411 as the axis before re-entering the drainage chamber 13, thereby making the upper filter plate 31 and the lower filter plate 32 that are adjusted up and down approach each other.

[0064] Reference Figure 4 and Figure 5 When the upper filter plate 31 and the lower filter plate 32 meet and intersect, that is, the bottom wall of the mounting plate 312 abuts against the moving rod 321, and the top wall of the moving plate 322 abuts against the mounting rod 311, the driving belt 412 continues to move, causing the moving rod 321 to push the mounting plate 312 to rotate upward with the mounting rod 311 as the axis. The mounting plate 312 is acted upon by the mounting torsion spring 313 to abut against the adjacent mounting plate 312 and slide on the side wall of the adjacent mounting plate 312, thereby scraping off impurities on the side wall of the mounting plate 312 and cleaning the mounting plate 312. At the same time, the mounting rod 311 pushes the moving plate 322 to rotate downward with the moving rod 321 as the axis. The moving plate 322 is acted upon by the moving torsion spring 323 to always abut against the adjacent moving plate 322 and slide on the side wall of the adjacent moving plate 322, thereby cleaning the moving plate 322.

[0065] When the mounting plate 312 rotates to a point where one movable plate 322 can pass between adjacent mounting plates 312, the movable plate 322 rotates to a point where one mounting plate 312 can pass between adjacent movable plates 322, so that the movable plate 322 and the mounting plate 312 are separated from each other, that is, the mounting plate 312 loses thrust, and the mounting torsion spring 313 restores its deformation, so that the adjacent mounting plates 312 are again pressed against each other to form a complete upper filter plate 31. Similarly, when the mounting rod 311 moves to separate from the movable plate 322, the movable plate 322 loses thrust, and the movable torsion spring 323 restores its deformation, so that the adjacent movable plates 322 are again pressed against each other to form a complete lower filter plate 32.

[0066] Reference Figure 2 and Figure 3 When the upper filter plate 31 moves to the location previously occupied by the lower filter plate 32, the lower filter plate 32 also moves to the top of the drainage chamber 13, serving as the new upper filter plate 31. When rainwater carries impurities from the air onto the new upper filter plate 31, the new upper filter plate 31 is relatively clean, meaning its filter holes 33 are not clogged by impurities. This allows rainwater to smoothly pass through the new upper filter plate 31 and enter the drainage chamber 13, ultimately flowing out through the filter holes 33 on the lower mounting plate 312. Because impurities on the mounting plate 312 face downward, they flush impurities from the bottom wall of the mounting plate 312, thereby cleaning the mounting plate 312. If a large amount of impurities accumulate on the lower filter plate 32, acting as the upper filter plate 31, the above steps are repeated to clean the lower filter plate 32, thereby maintaining drainage efficiency.

[0067] Reference Figure 2 and Figure 3 To ensure that the first connecting rod 42 and the second connecting rod 43 remain in a horizontal position during movement, thereby increasing the stability of the movement of the upper and lower filter plates 31 and 32, an auxiliary drive belt 50 is provided on the side of the outer plate 12 near the inner plate 11. The auxiliary drive belt 50 has the same structure as the drive drive belt 41 and is arranged opposite to it. Specifically, the auxiliary drive belt 50 includes an auxiliary belt 52 and two auxiliary wheels 51. Both auxiliary wheels 51 are rotatably connected to the outer plate 12 and correspond to the drive wheels 411. The auxiliary belt 52 is mounted on the two auxiliary wheels 51, and the auxiliary wheels 51 rotate to drive the auxiliary belt 52. The first connecting rod 42 is fixed to one side of the auxiliary belt 52 by an extension rod. The extension rod and the connecting rod are located on the same side of the central axis of the auxiliary drive belt 50. The second connecting rod 43 is fixed to the other side of the auxiliary belt 52 by an auxiliary rod. The auxiliary rod and the connecting rod are both located on the other side of the central axis of the auxiliary drive belt 50.

[0068] When the driving belt 41 drives the first connecting rod 42 and the second connecting rod 43 to move, the auxiliary driving belt 50 rotates synchronously, and also drives the first connecting rod 42 and the second connecting rod 43 to move, so that both sides of the first connecting rod 42 and the second connecting rod 43 are supported, so that the upper filter plate 31 and the lower filter plate 32 are not prone to tilting and deflection during movement, thereby increasing the stability of the movement of the upper filter plate 31 and the lower filter plate 32.

[0069] Reference Figure 3 and Figure 6 To drive the drive belt 41 and the auxiliary drive belt 50 to rotate synchronously, a rotating assembly 60 is provided on the connecting plate 20. The rotating assembly 60 includes two interlocking gears 65 and two interlocking racks 66. The two interlocking gears 65 are both rotatably connected to the connecting plate 20 and arranged horizontally. The two interlocking gears 65 mesh with each other. The two interlocking racks 66 are arranged vertically, and the two interlocking wheels are located between the two interlocking gears 65. A rotating rack 62 is fixed to the side wall of one of the interlocking racks 66 via a fixed plate 71. The fixed plate 71 is driven up and down within the inner plate 11 by an electric push rod 67. The electric push rod 67 is fixed to the top wall of the inner plate 11 by bolts. The output end of the electric push rod 67 is fixed to the fixed plate 71. The rotating rack 62 is vertically embedded in the inner plate 11, and the ends of the rotating rack 62 can penetrate the top and bottom walls of the inner plate 11. The rotating rack 62 meshes with the rotating gear 61, and the rotating gear 61 is coaxially fixed to the driving wheel 411 above.

[0070] Reference Figure 3 and Figure 6 A transmission rack 64 is fixed to the side wall of the other linkage rack 66 through a positioning plate 72. The transmission rack 64 is vertically embedded in the outer panel 12 and can move up and down in the outer panel 12. The end of the transmission rack 64 can pass through the top and bottom walls of the outer panel 12. The transmission rack 64 is engaged with a transmission gear 63, and the transmission gear 63 is coaxially fixed to the auxiliary wheel 51 above.

[0071] When it is necessary to swap the upper filter plate 31 and the lower filter plate 32, the electric drive is started to push the rotating rack 62 and the interlocking rack 66 fixed to the rotating rack 62 to move in the vertical direction. While driving the rotating gear 61 to rotate, the interlocking gear 65 is also driven to rotate. Then, another interlocking gear 65 drives the interlocking rack 66 connected to the transmission rack 64 and the transmission rack 64 to move, so that the two interlocking racks 66 move in the same direction and at the same time, that is, the drive belt 41 and the auxiliary transmission belt 50 rotate synchronously, and at the same time pull the first connecting rod 42 and the second connecting rod 43 on both sides to move the same distance, so that the upper filter plate 31 and the lower filter plate 32 always maintain a horizontal state and move, and are not prone to offset.

[0072] The implementation principle of the cantilevered aluminum panel curtain wall structure of the present embodiment is as follows: the upper filter plate 31 and the lower filter plate 32 cooperate to block all openings connecting the drainage chamber 13 to the outside world. When it rains, rainwater, carrying impurities from the air, falls to the top opening of the drainage chamber 13. Impurities in the rainwater cannot pass through the upper filter plate 31 and enter the drainage chamber 13. At the same time, the lower filter plate 32 also prevents impurities driven by wind from entering the drainage chamber 13 through the bottom opening of the drainage chamber 13. Rainwater can smoothly pass through the filter assembly 30 and enter the drainage chamber 13, and finally be discharged through the bottom opening of the drainage chamber 13. This prevents excessive accumulation of impurities in the drainage chamber 13, thereby preventing the inner diameter of the drainage chamber 13 from being reduced, and thus does not affect the drainage efficiency of the curtain wall body 10. At the same time, most of the rainwater falling on the curtain wall body 10 is discharged through the drainage chamber 13. In other words, the drainage chamber 13 distributes the rainwater that washes over the outer panel 12, making the outer panel 12 less susceptible to rainwater erosion and extending the service life of the outer panel 12.

[0073] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
