Description

Technical Field

[0001] This application relates to the field of energy-saving curtain wall technology, and in particular to an energy-saving curtain wall for buildings. Background Technology

[0002] A curtain wall is a non-load-bearing exterior wall cladding for a building. It hangs like a curtain and is a lightweight, decorative wall commonly used in modern large and high-rise buildings. It consists of curtain wall panels and a supporting structural system. Glass curtain walls are a popular choice for modern architecture due to their advantages such as good lighting and decorative properties.

[0003] However, because glass curtain walls are highly transparent, sunlight shines directly into the interior of the building through them, causing the indoor temperature to rise. At this time, air conditioning and other devices are usually used to cool the interior. Especially in the summer when the sun is strong, the indoor temperature rises too quickly, resulting in a large amount of electricity consumption. Summary of the Invention

[0004] In order to reduce the rate of indoor temperature rise and improve energy efficiency, this application provides an energy-saving curtain wall for buildings.

[0005] This application provides an energy-saving curtain wall for buildings, which adopts the following technical solution:

[0006] An energy-saving curtain wall for buildings includes several mounting frames fixedly installed on the exterior wall of a building and glass panels disposed within the mounting frames. The mounting frames include vertically arranged columns and horizontally arranged beams, which are fixedly connected. Two support rods are hinged to the outer side wall of each column, and a shading element for blocking sunlight is disposed between the two support rods. A drive assembly for driving the support rods to deflect along the column is disposed inside the column.

[0007] By adopting the above technical solution, when strong sunlight causes the indoor temperature to rise too quickly, the drive component deflects the support rod, allowing the shading component to block sunlight entering the room, effectively reducing the rate of temperature increase and achieving energy saving. Furthermore, the drive component can adjust the deflection position of the shading component according to the angle of sunlight, thereby maximizing the blocking of sunlight entering the room and improving energy efficiency.

[0008] Furthermore, the drive assembly includes a drive shaft and a power assembly for rotating the drive shaft. The drive shaft is rotatably inserted into the column along the length of the column, and the support rod is fixedly mounted on the drive shaft.

[0009] Furthermore, the crossbeam of the uppermost mounting frame is a top beam, the drive shaft passes through several columns and extends above the top beam, the power assembly includes a drive gear, a drive rack and a cylinder, the drive gear is fixedly mounted on the top of the drive shaft, the drive rack is slidably mounted on the top beam along the length of the top beam, the drive rack meshes with multiple drive gears, the cylinder is fixedly mounted on the top beam, and the piston rod of the cylinder is fixedly connected to the drive rack.

[0010] By adopting the above technical solution, during operation, the cylinder drives the drive rack to slide along the length of the top beam. The drive rack simultaneously drives multiple drive gears to rotate, which in turn drive the drive shaft to rotate. The drive shaft then deflects the support rod, thereby adjusting the angle of the light-shielding component on the support rod. This allows for real-time adjustment of the light-shielding component's position based on varying sunlight incidence angles, improving the shading effect without increasing the component's area. Furthermore, the same cylinder can simultaneously drive multiple drive shafts, thus synchronously rotating multiple light-shielding components, simplifying the structure and reducing failure rates and costs.

[0011] Furthermore, the outer wall of the column is provided with a clearance groove along the horizontal direction for the support rod to rotate.

[0012] Furthermore, the light-shielding component is configured as a light-shielding cloth, a sliding part is slidably provided on the support rod along its own length direction, the light-shielding cloth is fixedly connected to the sliding part, a pulling component is provided on the column for driving the sliding part to slide away from the column, and a winding component for winding the light-shielding cloth is provided inside the column.

[0013] Furthermore, the winding assembly includes a winding roller, a rotating shaft, and a drive source for driving the rotating shaft to rotate. The rotating shaft is rotatably inserted into the column along the length direction of the column. The winding roller is fixedly mounted on the rotating shaft, and the light-blocking cloth is wound around the winding roller.

[0014] Furthermore, the pulling assembly includes a pull rope, a guide wheel, and a take-up wheel. The guide wheel is rotatably mounted inside the support rod, the take-up wheel is fixedly mounted on the rotating shaft, the pull rope is wound around the take-up wheel, and one end of the pull rope passes around the guide wheel and is fixedly connected to the sliding part. The take-up direction of the take-up wheel is opposite to the take-up direction of the take-up roller.

[0015] Furthermore, an installation block is slidably disposed inside the support rod along the length direction of the support rod, the guide wheel is rotatably disposed on the installation block, and an elastic element is disposed inside the support rod for driving the installation block to move away from the column.

[0016] Furthermore, the crossbeam is fixedly provided with an abutment platform for contacting the glass plate along its own length direction, and the top and bottom walls of the crossbeam are both provided with abutment platforms. The crossbeam is also provided with a limiting component for limiting the position of the glass plate.

[0017] Furthermore, the top wall of the crossbeam is provided with an abutment groove along the length of the crossbeam, and the limiting member includes an abutment block. The abutment block is slidably disposed in the abutment groove in the vertical direction for abutting against the glass plate, and a compression spring is provided in the abutment groove for driving the abutment block to move upward.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. When strong sunlight causes indoor temperatures to rise too quickly, the drive assembly deflects the support rod, allowing the shading component to block sunlight from entering the room, effectively slowing the rate of temperature increase and achieving energy savings. The drive assembly adjusts the deflection position of the shading component according to the angle of sunlight, thereby maximizing the blocking of sunlight and further enhancing energy efficiency.

[0020] 2. When there is no need to block the sun but to improve the lighting effect, the blackout cloth can be rolled up using the roll-up assembly to prevent the blackout cloth from blocking the sun and ensure the lighting effect. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0029] This application discloses an energy-saving curtain wall for buildings.

[0030] Reference Figure 1 An energy-saving curtain wall for buildings includes several mounting frames fixedly installed on the exterior wall of a building and glass panels 1 installed within the mounting frames. Each mounting frame includes vertically arranged columns 2 and horizontally arranged beams 3, which are fixedly connected. Columns 2 on the same side of adjacent mounting frames are coaxially arranged. The beam 3 of the uppermost mounting frame is the top beam.

[0031] Reference Figure 2 The outer wall of the column 2 is hinged with two support rods 4, and a shading element for blocking sunlight is provided between the two support rods 4. The shading element is a shading cloth 41, which can block sunlight from passing through. The shading cloth 41 can be made of polyester.

[0032] Reference Figure 2 The column 2 is equipped with a drive assembly 5 for driving the support rod 4 to deflect along the column 2. The drive assembly 5 includes a drive shaft 51 and a power assembly for rotating the drive shaft 51. The drive shaft 51 is rotatably inserted into the column 2 along its length. The drive shaft 51 passes through several columns 2 and extends to the top beam. The support rod 4 is fixedly mounted on the drive shaft 51.

[0033] Reference Figure 2 The power assembly includes a drive gear 521, a drive rack 522, and a cylinder 523. The drive gear 521 is fixedly mounted on the top of the drive shaft 51. The drive rack 522 is slidably mounted on the top beam along the length of the top beam. The drive rack 522 meshes with multiple drive gears 521. The cylinder 523 is fixedly mounted on the top beam, and the piston rod of the cylinder 523 is fixedly connected to the drive rack 522.

[0034] Reference Figure 2 To expand the rotation range of the shading component, a clearance groove 21 for the support rod 4 to rotate is provided on the outer side wall of the column 2 in the horizontal direction. The two ends of the clearance groove 21 extend to the two side walls of the column 2, so that the deflection angle range of the shading component is close to 180 degrees. Since the angle of sunlight is different in the morning and afternoon, the angle of the shading component can be adjusted according to actual needs.

[0035] During operation, cylinder 523 drives drive rack 522 to slide along the length of the top beam. Drive rack 522 simultaneously drives multiple drive gears 521 to rotate, which in turn drives drive shaft 51 to rotate. Drive shaft 51 then deflects support rod 4, thereby adjusting the angle of the light-shielding component on support rod 4. This allows for real-time adjustment of the light-shielding component's position based on varying sunlight incidence angles, improving the shading effect without increasing the component's area. Furthermore, the same cylinder 523 can simultaneously drive multiple drive shafts 51 to rotate, thus synchronously rotating multiple light-shielding components, simplifying the structure and reducing failure rate and cost.

[0036] Among them, reference Figure 3 and Figure 4 A sliding part 42 is slidably provided on the support rod 4 along its own length direction. On the two support rods 4 of the same mounting frame, the bottom wall of the upper support rod 4 has a strip groove, and the top wall of the lower support rod 4 has a strip groove. The strip grooves are arranged along the length direction of the support rod 4. The sliding part 42 is a slider, which is slidably connected to the strip groove. The light-blocking cloth 41 is fixedly connected to the sliding part 42.

[0037] Reference Figure 3 and Figure 4 The column 2 is provided with a pulling assembly for driving the sliding part 42 to slide away from the column 2. The pulling assembly includes a pull rope 61, a guide wheel 62 and a take-up wheel 63. The guide wheel 62 is rotatably disposed inside the support rod 4. The take-up wheel 63 is fixedly disposed on the rotating shaft 72. The pull rope 61 is wound around the take-up wheel 63, and one end of the pull rope 61 passes around the guide wheel 62 and is fixedly connected to the sliding part 42. The take-up direction of the take-up wheel 63 is opposite to the take-up direction of the take-up roller 71.

[0038] Reference Figure 3 and Figure 4 The column 2 is equipped with a winding assembly 7 for winding up the light-blocking cloth 41. The winding assembly 7 includes a winding roller 71, a rotating shaft 72, and a drive source 73 for driving the rotating shaft 72 to rotate. The rotating shaft 72 is rotatably inserted into the column 2 along its length. The winding roller 71 is fixedly mounted on the rotating shaft 72, and the light-blocking cloth 41 is wound around the winding roller 71. In this embodiment, the diameter of the winding roller 71 is approximately equal to the diameter of the take-up reel 63, so that when the winding roller 71 winds up the light-blocking cloth 41, the winding length of the light-blocking cloth 41 is equal to or approximately equal to the unwinding length of the take-up reel 63.

[0039] Reference Figure 3 and Figure 4 To further ensure that the winding length of the blackout cloth 41 is equal to or approximately equal to the unwinding length of the take-up reel 63, a mounting block 43 is slidably installed inside the support rod 4 along its length. An extension rod 431 is fixedly installed on the mounting block 43 along the length of the support rod 4, and a guide wheel 62 is rotatably mounted on the extension rod 431. A fixing tube 45 is fixedly installed inside the support rod 4 at the end away from the column 2 along its length. The mounting block 43 is slidably installed inside the fixing tube 45. An elastic element, a tension spring 451, is installed inside the support rod 4 to drive the mounting block 43 to move away from the column 2. One end of the tension spring 451 is fixedly connected to the bottom wall of the fixing tube 45, and the other end is fixedly connected to the mounting block 43. During the winding or unwinding process of the blackout cloth 41, if the movement speed of the blackout cloth 41 is different from the movement speed of the pull rope 61, the tension spring 451 will pull the rope 61 to compensate for the speed difference, allowing the blackout cloth 41 to be wound or unwound smoothly.

[0040] When the light-blocking cloth 41 is wound up, the drive source 73 drives the rotating shaft 72 to rotate, which in turn drives the take-up roller 71 to rotate, causing the light-blocking cloth 41 to move into the column 2. The light-blocking cloth 41 is wound onto the take-up roller 71, and at the same time, the light-blocking cloth 41 pulls the pull rope 61 to move. During this process, the rotating shaft 72 also drives the take-up wheel 63 to rotate. At this time, the take-up wheel 63 is in the unwinding state, so that the light-blocking cloth 41 can be wound onto the take-up roller 71. Similarly, when the rotating shaft 72 rotates in the opposite direction, the take-up wheel 63 is in the take-up state, pulling the pull rope 61 to move. The pull rope 61 pulls the sliding part 42 and the light-blocking cloth 41 to move away from the column 2. During this process, the take-up roller 71 is in the unwinding state.

[0041] Among them, reference Figure 5 and Figure 6 A contact platform 31 for contacting the glass plate 1 is fixedly provided on the crossbeam 3 along its own length direction. The top and bottom walls of the crossbeam 3 are both provided with contact platforms 31. The length of the contact platform 31 is equal to the length of the crossbeam 3, and the contact platform 31 is integrally formed with the crossbeam 3.

[0042] Reference Figure 5 and Figure 6 The top wall of the crossbeam 3 has an abutment groove 32 along its length. A limiting member for positioning the glass plate 1 is provided on the crossbeam 3. The limiting member includes an abutment block 321, which is slidably disposed vertically within the abutment groove 32 to abut against the glass plate 1. A guide plate 322 is slidably disposed vertically within the abutment groove 32, abutting against the side wall of the abutment groove 32. A drainage hole 324 is provided on the bottom wall of the abutment groove 32, penetrating the outer side wall of the crossbeam 3 to facilitate the smooth drainage of rainwater from the abutment groove 32.

[0043] Reference Figure 5 The width of the abutment groove 32 is greater than the width of the abutment block 321. The abutment block 321 is slidably disposed on the guide plate 322 along the length direction perpendicular to the crossbeam 3. A compression spring 323 is provided in the abutment groove 32 to drive the abutment block 321 to move upward. One end of the compression spring 323 abuts against the bottom wall of the abutment groove 32, and the other end abuts against the guide plate 322.

[0044] Among them, reference Figure 5 and Figure 6 An adjusting screw 33 is threaded through the inner thread of the crossbeam 3. The adjusting screw 33 is perpendicular to the crossbeam 3. A dovetail block 331 is ball-jointed at one end of the adjusting screw 33 near the abutment block 321. Specifically, a ball is fixedly mounted at one end of the adjusting screw 33, and the dovetail block 331 is rotatably mounted on the ball. A dovetail groove 3211 is formed vertically on the side wall of the abutment block 321 near the adjusting screw 33, and the dovetail block 331 is slidably mounted in the dovetail groove 3211. By rotating the adjusting screw 33, the abutment block 321 can be pushed or pulled to move in a direction perpendicular to the length of the crossbeam 3.

[0045] Reference Figure 5 and Figure 6 The abutment block 321 has an arc-shaped guide surface 3212 on its side wall away from the glass plate 1. After the bottom end of the glass plate 1 is placed on the top wall of the crossbeam 3, the glass plate 1 is pushed, and the glass plate 1 contacts the guide surface 3212 of the abutment block 321, causing the abutment block 321 to move downward into the abutment groove 32, so that the glass plate 1 can be smoothly assembled. After the glass plate 1 abuts against the abutment platform 31, the bottom wall of the glass plate 1 disengages from the abutment block 321, and the abutment block 321 moves upward under the action of the compression spring 323. Then, the adjusting screw 33 is rotated to drive the abutment block 321 to abut against the glass plate 1. This facilitates the installation of the glass plate 1 and ensures a tight fit between the abutment block 321 and the glass plate 1, improving the stability of the glass plate 1 installation.

[0046] The implementation principle of this application embodiment is as follows: When strong sunlight causes the indoor temperature to rise too quickly, the cylinder 523 drives the drive rack 522 to slide along the length of the top beam. Simultaneously, the drive rack 522 drives multiple drive gears 521 to rotate, which in turn drives the drive shaft 51 to rotate. The drive shaft 51 then deflects the support rod 4, thereby adjusting the angle of the light-shielding component on the support rod 4. This allows the light-shielding component to block sunlight entering the room, effectively reducing the rate of temperature rise and achieving energy savings. Furthermore, the drive assembly 5 can adjust the deflection position of the light-shielding component according to the angle of sunlight, thereby maximizing the blocking of sunlight entering the room and improving energy efficiency.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
