Description

Technical Field

[0001] The present application relates to the technical field of glass curtain walls, and in particular to a ventilation mechanism for a glass curtain wall. Background Art

[0002] Glass curtain wall refers to the building's external protective structure or decorative structure that has a certain displacement capability relative to the main structure and does not share the forces acting on the main structure. Generally speaking, glass curtain walls are installed on the outside of apartments and commercial and residential buildings to isolate the outside from the interior. The walls are generally single-layer glass and double-layer glass.

[0003] At present, glass curtain walls usually realize ventilation of high floors by setting a window that can be moved up and down or left and right for easy opening. Such a setting requires that the entire window is pushed out to the outside and then fixed by supporting rods, etc. (hereinafter collectively referred to as fixing components); however, in actual applications, such a setting will cause the fixing components to loosen due to frequent pushing after long-term use, and the fixing components exposed to the outside will also be damaged to a certain extent due to the influence of rainfall, etc., which will greatly affect its fixing effect, resulting in the situation that the window cannot be opened or cannot be closed after opening. Utility Model Content

[0004] In order to reduce the damage of the fixing components due to frequent pushing or rainfall, thereby affecting the fixing effect and causing the window to be unable to open or unable to close after opening, the present application provides a ventilation mechanism for a glass curtain wall.

[0005] The ventilation mechanism of a glass curtain wall provided in this application adopts the following technical solution:

[0006] A ventilation mechanism for a glass curtain wall comprises a window frame, wherein a first glass plate and a second glass plate are respectively provided at openings at both ends of the window frame; a cavity is formed between the first glass plate, the second glass plate and the inner wall of the window frame; a first ventilation slot is provided on the first glass plate and a second ventilation slot is provided on the second glass plate, and the first ventilation slot and the second ventilation slot are both connected to the cavity; a sealing plate is slidably provided on the second glass plate, the sealing plate is in contact with the second glass plate and covers the opening of the second ventilation slot.

[0007] By adopting the above technical solution, ventilation between the room and the outside can be achieved by sliding the sealing plate during use. Such a setting avoids the pushing and pulling of the entire window, has a simple structure and is easy to operate, and avoids the entire window from being damaged by the fixing components due to frequent pushing or rainfall, thereby affecting its fixing effect and causing the window to be unable to be opened or unable to be closed after opening, or even falling off. This greatly improves safety and meets the ventilation needs of high floors.

[0008] In a specific possible implementation scheme, a placement groove is provided on the side of the sealing plate away from the second glass plate, a reset spring is provided on the bottom wall of the placement groove, and a button is provided at the other end of the reset spring; a second through groove is provided on the sealing plate, and the second through groove is communicated with the placement groove; a limit rod is provided on the button, and both ends of the limit rod extend out of the sealing plate through the second through groove; and both ends of the limit rod are provided with limit blocks;

[0009] Two limit boxes are arranged on the second glass plate, and the two limit boxes are respectively located above and below the sealing plate; a limit opening for the limit block to pass through is opened on the surface of the limit box close to the sealing plate, one end of the limit rod is inserted into the limit box through the limit opening, and the limit block inserted into the limit box contacts the inner wall of the limit box.

[0010] By adopting the above technical solution, when in use, press and hold the button to squeeze the return spring so that the limit block located below can be pulled out of the lower limit box through the lower limit opening in the subsequent movement, and then the sealing plate is moved in the vertical upward direction until the limit block at the other end is inserted into the upper limit box through the upper limit opening, that is, when the second ventilation groove is fully exposed, the button is released at this time, and the return spring drives the button to restore the deformation, the button drives the limit rod, and the limit rod drives the limit block to move together in the direction away from the second glass plate, and finally the limit block hits the inner wall of the limit box. At this time, the limit block cannot be detached from the limit box through the limit opening, thereby achieving the fixation of the sealing plate during sliding.

[0011] In a specific implementation manner, the limiting block is a triangular block.

[0012] By adopting the above technical solution, the triangular block has a sloped surface, and compared with shapes such as a square, the sloped surface has a certain guiding effect, so that the triangular block-shaped limit block can be more smoothly inserted into the corresponding limit box through the limit opening, and the bottom surface of the triangle can be hooked on the bottom wall of the limit box when the limit rod contacts the side wall of the limit opening, thereby achieving the fixation of the sealing plate.

[0013] In a specific feasible implementation scheme, a lifting mechanism is provided on both side walls of the cavity close to the window frame, and the lifting mechanism includes two rotating shafts arranged parallel to each other, and the two rotating shafts are distributed up and down and are sleeved with conveyor belts; a plurality of pulling ropes are distributed on the conveyor belt along its conveying direction; at the same horizontal position, the ends of two pulling ropes located on the same side of the conveyor belt away from the conveyor belt are connected with air guide blades; a plurality of support blocks are provided on the conveyor belt along the length direction of the conveyor belt, and the upper surface of the support block is in contact with the lower surface of the air guide blade; the end of the air guide blade away from the pulling rope is provided with bristles along its length direction, and the bristles are in contact with the first glass plate or the second glass plate.

[0014] By adopting the above technical solution, when in use, the rotating shaft drives the conveyor belt to start lifting and lowering (that is, one side of the conveyor belt moves upward and the other side moves downward), and the conveyor belt drives the pulling rope and the support block, thereby driving the bristles on the air guide blades to sweep the first glass plate or the second glass plate back and forth, thereby effectively cleaning the dust adsorbed on the glass plate in the cavity during ventilation.

[0015] In a specific possible implementation scheme, a supporting square rod is vertically arranged in the cavity, and the supporting square rod is connected to the inner wall of the window frame; a groove is provided on the supporting square rod, and an adjusting component for adjusting the inclination of the air guide blade is provided in the groove.

[0016] In a specific feasible implementation scheme, the adjustment component includes a vertically arranged threaded rod, the threaded rod is rotatably connected to the bottom wall of the groove, a second motor is provided at one end of the threaded rod, and the output shaft of the second motor is coaxially connected to the threaded rod; a transmission block is threadedly connected to the threaded rod; a plurality of first through grooves are provided on the supporting square rod along the length direction of the supporting square rod, and a seesaw is provided on both side walls opposite to each other of the transmission block, and the seesaw extends out of the supporting square rod through the first through groove and contacts with the wind guide blade on the same side.

[0017] By adopting the above technical solution, when in use, the second motor is started to control the rotation of the threaded rod, and the transmission block moves along the length direction of the threaded rod under the restriction of the seesaw. As the transmission block moves, the seesaw gradually tilts to lift the air guide blades. At this time, the cross-sections of the two air guide blades at the same horizontal position are V-shaped, which plays a guiding role to a certain extent and effectively speeds up the efficiency of ventilation.

[0018] In a specific embodiment, the first glass plate is further provided with ventilation holes.

[0019] By adopting the above technical solution, the ventilation hole is used to communicate with the air outlet of an air inlet pipe, and the air inlet of the air inlet pipe is connected to the blower fixed on the outer wall; when there is no wind or the wind volume is small in the external environment, the blower is started, and the outside air can be transported into the cavity through the air inlet pipe and the ventilation hole, and then flow into the room through the second ventilation groove to realize air circulation.

[0020] In a specific possible implementation manner, a drainage hole is provided on the bottom wall of the window frame, and the drainage hole is communicated with the cavity.

[0021] By adopting the above technical solution, when rainwater enters the cavity through the first ventilation slot in rainy weather to form water accumulation, or when there is a significant difference between the outside temperature and the indoor temperature causing a large amount of condensation water to form in the cavity, the accumulated water can be discharged to the outside through the drainage hole.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By arranging a first ventilation groove on the first glass plate and arranging a second ventilation groove connected with the first ventilation groove on the second glass plate, ventilation between the room and the outside is simply achieved, and the pushing and pulling of the entire window is avoided. The structure is simple and the operation is convenient. The entire window is prevented from being damaged by the fixing components due to frequent pushing or rainfall, thereby affecting its fixing effect and causing the window to be unable to be opened or unable to be closed after opening, or even falling off, thereby greatly improving safety.

DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0032] The embodiment of the present application discloses a ventilation mechanism for a glass curtain wall.

[0033] Reference Figure 1 and Figure 2 A ventilation mechanism of a glass curtain wall includes a first glass plate 02, a second glass plate 03 and a window frame 01; the first glass plate 02 and the second glass plate 03 are respectively arranged at two openings of the window frame 01, and a cavity is formed between the first glass plate 02 and the second glass plate 03 and the inner wall of the window frame 01. In this embodiment, the interval between the first glass plate 02 and the second glass plate 03 is 3-5 cm.

[0034] It should be particularly noted that the window frame 01 of the present embodiment is formed by welding four strip frames (not shown in the figure) with inclined surfaces at both ends, and two concave frames (not shown in the figure) arranged along the length direction of the strip frame are integrally formed on the inner side wall (i.e., the shorter side) of the strip frame, and before welding, the first glass plate 02 and the second glass plate 03 are respectively inserted into the corresponding concave frames and bonded to the inner side walls of the concave frames with glass glue.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The first glass plate 02 is provided with a plurality of first ventilation slots 021. In this embodiment, two first ventilation slots 021 are respectively distributed up and down and arranged horizontally are used as an example; the second glass plate 03 is provided with a second ventilation slot 031. Both the first ventilation slot 021 and the second ventilation slot 031 are connected to the cavity; the shape of the ventilation slot in this embodiment is not limited, and it can be a waist-shaped first through slot or a square first through slot. The first glass plate 02 is also provided with a ventilation hole 022 connected to the cavity. In this embodiment, the ventilation hole 022 is connected to the air outlet of an air inlet pipe (not shown in the figure), and the air inlet of the air inlet pipe is connected to a blower (not shown in the figure) fixed on the outer wall.

[0036] It should be noted that, during installation, the first glass plate 02 of this embodiment is located on the side in contact with the outside world and the second glass plate 03 is located on the side in contact with the indoor space. In the case of natural ventilation, when the indoor temperature is high, according to the chimney effect, the hot and humid air in the room flows into the cavity through the second ventilation slot 031, and then is discharged to the outside through the first ventilation slot 021 located above. At the same time, the cold air from the outside flows into the cavity through the first ventilation slot 021 located below, and then flows into the room through the second ventilation slot 031; when the outside temperature is high, the opposite is true, thereby achieving mutual circulation of air. In the case of mechanical ventilation (i.e., there is no wind or little wind in the environment), the blower is turned on, and the outside air is transported into the cavity through the air inlet pipe, and then flows into the room through the second ventilation slot 031 to achieve air circulation.

[0037] In order to effectively prevent the indoor air from circulating with the outside world when the air conditioner is turned on in summer or winter, the following settings are adopted:

[0038] Reference Figure 1 , Figure 3 and Figure 4 , a sealing assembly 1 is provided on the second glass plate 03, and the sealing assembly 1 includes a sealing plate 11, a reset spring 12, a button 14 and a limit rod 16; two limit frames 13 are fixedly connected to the second glass plate 03, and the cross section of the limit frame 13 is L-shaped and two limit frames 13 are vertically provided. The limit frames 13 of this embodiment are fixedly connected to the side of the second glass plate 03 away from the cavity by glass glue; the sealing plate 11 is located between the two limit frames 13 and slidably cooperates with the two limit frames 13, the bottom of the sealing plate 11 is in contact with the surface of the second glass plate 03, and the sealing plate 11 covers the opening of the second ventilation slot 031 in the default state; for better sealing, a sealing ring (not shown in the figure) can be fixedly provided at the bottom of the sealing plate 11;

[0039] Reference Figure 1 , Figure 3 and Figure 4A placement groove 111 is provided on the side of the sealing plate 11 away from the second glass plate 03, one end of the reset spring 12 is fixedly connected to the bottom of the placement groove 111, and the other end is fixedly connected to the button 14; a second through groove 112 is also provided on the sealing plate 11, and the second through groove 112 passes through two opposite side walls of the sealing plate 11; a limiting rod 16 is penetrated by the end of the button 14 close to the reset spring 12, and the limiting rod 16 extends out of the sealing plate 11 through the second through groove 112; both ends of the limiting rod 16 are provided with limiting blocks 161, and the limiting blocks 161 of this embodiment take triangular blocks as an example; a limiting box 15 is fixedly connected to the second glass plate 03, and two limiting boxes 15 are provided and are respectively located above and below the sealing plate 11, and a limiting opening 151 for the limiting block 161 to pass through is provided on the side of the limiting box 15 close to the sealing plate 11;

[0040] When ventilation is needed, press the button 14 to allow the limit block 161 at the lower end to pass through the corresponding limit opening 151, then keep pressing the button 14 to slide the sealing plate 11 upward along the limit frames 13 on both sides until the limit block 161 at the upper end is inserted into the corresponding limit opening 151. At this time, the second ventilation groove 031 is connected with the indoor space. Finally, release the button 14, and the return spring 12 pushes the button 14 to the outside of the sealing plate 11 after losing the extrusion force until the limit rod 16 hits the side wall of the second through groove 112. At this time, due to the displacement of the limit block 161 of the limit rod 16, the bottom of the limit block 161 hits the inner wall of the limit box 15 and can no longer pass through the limit opening 151, thereby achieving the fixation of the sealing plate 11.

[0041] Since air is often circulated and exchanged in the cavity, after long-term use, dust and other particles in the air are easily adsorbed on the opposite surfaces of the first glass plate 02 and the second glass plate 03, causing obstruction of vision. Therefore, the following settings are adopted:

[0042] Reference Figure 5 , a lifting mechanism is provided in the cavity, and one lifting mechanism is provided on each of the inner side walls opposite to the window frame 01. The lifting mechanism is a vertically placed conveyor belt, and this embodiment takes a reciprocating belt conveyor as an example; the lifting structure includes two rotating shafts 21 arranged parallel to each other, a conveyor belt 22, and a first motor (not shown in the figure). Both rotating shafts 21 are rotatably connected to the corresponding inner side walls of the window frame 01 in a direction perpendicular to the window frame 01, and the first motor is fixedly arranged in a receiving groove (not shown in the figure) pre-opened at the corresponding position of the window frame 01. The first motor is located on the side of one of the rotating shafts 21, and the output shaft of the first motor is coaxially connected to the rotating shaft 21. The conveyor belt 22 of this embodiment is sleeved on the outside of the two rotating shafts 21 and can make annular belt-like motion with the rotation of the rotating shaft 21 (i.e., forming a linkage transmission).

[0043] Reference Figure 3 and Figure 5, a plurality of pulling ropes 221 are fixedly connected to the conveyor belt 22 along the conveying direction of the conveyor belt 22, and the pulling ropes 221 are evenly distributed. In the default state, the horizontal positions of the pulling ropes 221 on both sides of the same conveyor belt 22 correspond one to one, and the horizontal positions of the pulling ropes 221 on different conveyor belts also correspond one to one (that is, the pulling ropes 221 on the two conveyor belts 22 are symmetrically arranged); the ends of the two pulling ropes 221 located on the same side of the conveyor belt 22 at the same horizontal position away from the conveyor belt 22 are fixedly connected with air guide blades 3; a plurality of supporting blocks 23 are provided on the conveyor belt 22 along the length direction of the conveyor belt 22, and the upper surface of the supporting block 23 is in contact with the lower surface of the air guide blade 3; in the default state, the air guide blade 3 remains horizontal under the action of the pulling ropes 221; the side wall of the air guide blade 3 close to the first glass plate 02 or the second glass plate 03 is fixedly connected with bristles 31 arranged along the length direction of the air guide blade 3, and the other end of the bristles 31 is in contact with the first glass plate 02 or the second glass plate 03.

[0044] When the first glass plate 02 and the second glass plate 03 need to be cleaned, the first motor is started, the first motor drives the rotating shaft 21 to rotate, the rotating shaft 21 drives the conveyor belt 22 to move, the pulling rope 221 and the support block 23 on the conveyor belt 22 drive the air guide blade 3 to rise or fall (one side rises and the other side falls), and the bristles 31 sweep the dust back and forth to clean the corresponding first glass plate 02 or the second glass plate 03.

[0045] It should be particularly noted that the first motor of this embodiment controls the rotating shaft 21 to rotate in the opposite direction when the air guide blade 3 located at the top or bottom end moves to the same horizontal position as the axis of the rotating shaft 21, thereby completing a cycle; during this cycle, the position of the next air guide blade 3 can at least move to the starting position of the previous air guide blade 3 before movement, thereby helping to greatly reduce the existence of cleaning dead corners.

[0046] Since rainwater can easily enter the cavity through the first ventilation slot 021 in rainy weather, and water may accumulate, the following settings are adopted:

[0047] Reference Figure 3 and Figure 5 A drainage hole 011 communicating with the cavity is provided at the bottom of the window frame 01, and the accumulated water can be discharged to the outside through the drainage hole 011.

[0048] In order to accelerate the circulation speed of gas exchange in the cavity and enhance the ventilation effect, the following settings are adopted:

[0049] Reference Figure 5 and Figure 6 A supporting square rod 4 is vertically arranged between the two rotating shafts 21 of each lifting mechanism, and the side walls of the supporting square rod 4 are respectively fixedly connected to the inner side walls of the window frame 01 on the corresponding side;

[0050] It should be noted that the side wall of the air guide blade 3 is fitted with the side wall of the supporting square rod 4 and the edge of the air guide blade 3 at the fitting position is set as a rounded corner (that is, the supporting square rod 4 will not interfere with the air guide blade 3);

[0051] A groove 41 is provided on the supporting square rod 4 along the length direction of the supporting square rod 4, and an adjustment assembly 5 is provided in the groove 41; the adjustment assembly 5 includes a threaded rod 51, a transmission block 52, a second motor 54 and a seesaw 53, the threaded rod 51 is vertically arranged in the groove 41 and is rotatably connected to the bottom wall of the groove 41. In this embodiment, in order to improve the stability of the threaded rod 51, a fixing plate (not shown in the figure) can be fixedly connected at the opening of the groove 41, and the threaded rod 51 passes through the fixing plate and is rotatably connected to the fixing plate to achieve stability; the second motor 54 is fixedly connected to the fixing plate, and the output shaft of the second motor 54 is coaxially connected to the threaded rod 51;

[0052] Reference Figure 3 , Figure 5 and Figure 6 A plurality of first through grooves 42 are provided on the supporting square rod 4 along the length direction of the supporting square rod 4, and the first through grooves 42 are connected with the grooves 41; a plurality of transmission blocks 52 are evenly distributed on the threaded rod 51 along the length direction of the threaded rod 51, and the transmission blocks 52 are threadedly connected with the threaded rod 51; one transmission block 52 corresponds to two rockers 53 and the two rockers 53 are respectively hinged on the opposite surfaces of the transmission block 52, and the rocker 53 extends out of the corresponding first through groove 42 and contacts the lower surface of the air guide blade 3 on the same side; the two adjacent side edges of the two air guide blades at the same horizontal position are rounded.

[0053] In order to effectively ensure the smooth circulation of air, one of the two first ventilation slots 021 in the present embodiment is located below the top wind guide blade 3 in the default state, and the other is located above the bottom wind guide blade 3 in the default state, while the second ventilation slot 031 is located in the middle of the second glass plate 03; thereby, the overlap of the flow trajectories of the external cold and hot air and the indoor air after entering the cavity can be greatly reduced, thereby greatly improving the efficiency of ventilation.

[0054] It should be particularly noted that the seesaw 53 in this embodiment will not affect the above-mentioned cleaning process: since the air guide blade 3 and the conveyor belt 22 are connected only by the pulling rope 221, when the conveyor belt 22 moves, the seesaw 53 on the downward movement side will support the corresponding air guide blade 3 so that the pulling rope 221 is in a relaxed state; therefore, the above-mentioned cleaning process will be performed alternately by one side of the bristles 31 located on both sides of the conveyor belt 22.

[0055] The implementation principle of a ventilation mechanism of a glass curtain wall in the embodiment of the present application is:

[0056] When in use, press and hold the button 14 to slide the sealing plate 11 upward along the length direction of the limiting frame 13 until the limiting block 161 is inserted into the limiting opening 151 (at this time, the second ventilation slot 031 is completely exposed), then release the button 14, the reset spring 12 drives the button 14 and the button 14 drives the limiting rod 16 to move away from the second glass plate 03, at this time, the bottom of the limiting block 161 contacts the inner wall of the limiting box 15, and cannot pass through the limiting opening 151 to fix the sealing plate 11;

[0057] After the second ventilation slot 031 is connected with the room, the second motor 54 is started to drive the threaded rod 51 to rotate, and the transmission block 52 drives one end of the seesaw 53 to move downward along the length direction of the threaded rod 51 under the limit of the seesaw 53, and the seesaw 53 is tilted. The end of the seesaw 53 away from the transmission block 52 raises the corresponding transmission blade to a certain angle. At this time, the cross section of the air guide blade 3 at the same horizontal position in the cavity is V-shaped, which can effectively guide the flowing air or wind, and accelerate the speed of air circulation to a certain extent;

[0058] The outside air entering through the first ventilation slot 021 is mainly concentrated in the upper or lower part of the cavity (hot air is on the upper part, cold air is on the lower part) under the guidance of the wind guide blades, and then the outside air enters the room through the second ventilation slot 031, while the indoor air enters the middle part of the cavity through the second ventilation slot 031 and is discharged to the outside through the first ventilation slot 021 under the guidance of the wind guide blades.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
