Description

Technical Field

[0001] The invention relates to the technical field of curtain wall ventilation, in particular to a double-layer energy-saving curtain wall ventilation structure. Background Art

[0002] Double-layer curtain wall is also called heat channel curtain wall, breathing curtain wall, ventilation curtain wall, energy-saving curtain wall, etc. It consists of two layers of facade structure, forming an air buffer layer between indoor and outdoor, with air inlet at the bottom and air outlet at the top, which can control the air flow state between them. With the development of science and the continuous improvement of people's living standards, the current requirements for curtain walls in buildings are getting higher and higher, and the ventilation and heat transfer properties of curtain walls are also more valued.

[0003] However, during the use or installation of the double-layer curtain wall, the internal ventilation effect is currently poor. If the internal air flow only relies on the flow of natural wind for ventilation or exchange, the heat of the double-layer curtain wall cannot be processed in time, resulting in the heat of the internal space gradually increasing with the sun's exposure. Because the traditional technical solution only provides a ventilation duct for the inner curtain wall and the outer curtain wall, but if the flow of natural wind in the air is small, the air flow between the inner curtain wall and the outer curtain wall cannot be quickly replaced to achieve cooling, thereby reducing the service life of the curtain wall as the temperature rises, and as the air flow between the inner curtain wall and the outer curtain wall is small, the heat will be radiated into the room through the inner curtain wall, causing the problem of increased indoor temperature. Therefore, a double-layer energy-saving curtain wall ventilation structure is proposed to solve the above-mentioned problems. Summary of the invention

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 7 A double-layer energy-saving curtain wall ventilation structure comprises an upper wall 1 and a lower wall 2, on which a connecting piece 3 is installed, and an outer curtain wall 4 and an inner curtain wall 7 are installed on the connecting piece 3; a flow air cavity is arranged between the inner curtain wall 7 and the outer curtain wall 4; a duct assembly 5 for air intake is also arranged on the upper wall 1 and the lower wall 2; a ventilation assembly 6 for actively pushing the airflow in the flow air cavity is arranged on the upper wall 1 and the lower wall 2; the ventilation assembly 6 comprises a power part, a moving part and a cleaning part; the power part drives the circulating motion of the moving part, thereby accelerating the flow of air in the flow air cavity, and at the same time controls the cleaning part to automatically clean the surface attachments of the inner curtain wall 7 and the outer curtain wall 4.

[0032] In this embodiment, the connecting member 3 includes an upper connecting frame 301 and a lower connecting frame 302. The upper connecting frame 301 is fixed to the upper wall 1 by bolts, and the lower connecting frame 302 is fixed to the lower wall 2 by bolts. The upper connecting frame 301 and the lower connecting frame 302 are both provided with mounting grooves, and the outer curtain wall 4 is connected to the upper connecting frame 301 and the lower connecting frame 302 through the mounting grooves. A bottom bracket 303 is also installed on the lower wall 2, and the inner curtain wall 7 is installed on the bottom bracket 303. The upper connecting frame 301 and the lower connecting frame 302 can provide an installation space for the outer curtain wall 4 to achieve medium installation. Curtain walls of different specifications can be installed according to different types of upper connecting frames 301 and lower connecting frames 302.

[0033] Furthermore, the air duct assembly 5 includes a vertical air duct 501, and a plurality of louvers 503 are rotatably connected to the vertical air duct 501. Side wind slots 502 are provided on both sides of the vertical air duct 501, and the side wind slots 502 are located inside the flow air cavity. An adjustment device is provided inside the vertical air duct 501. The vertical air duct 501 is provided to realize the communication between the flow air cavity and the outside world, thereby providing a spatial channel for air flow. The outside air will enter the inside of the vertical air duct 501 through the channel of the louver 503, and then enter the inside of the flow air cavity from the side wind slots 502 on both sides. The flow air cavity is also interconnected with the plurality of vertical air ducts 501, so the airflow will be in an interconnected state.

[0034] Furthermore, the adjusting device includes an adjusting rod 505, the right end of which is connected to a rotating sleeve 507, the surface of the adjusting rod 505 is threadedly connected to a threaded sleeve 506, the threaded sleeve 506 is rotatably connected to a support rod 508, the top of the support rod 508 is rotatably connected to a connecting plate 509, the connecting plate 509 is connected to a sliding rack 510, and pinions 511 are fixedly connected to both sides of the louver 503, the surface of the sliding rack 510 is provided with teeth, and the teeth are meshed with the pinion 511. The threaded sleeve 506 with threaded connection is controlled to move forward and backward by rotating the adjusting rod 505. When moving forward, the triangularly connected support rod 508 will rotate, thereby driving the connecting plate 509 to move upward, and then driving the sliding rack 510 to move upward. The sliding rack 510 will drive the teeth to engage and rotate with multiple small gears 511, and the rotation of the small gears 511 will drive the multiple louvers 503 to rotate, so the louvers 503 will be in an open state. Therefore, the operator can directly control the size of the opening of the external air duct assembly 5 according to the rotation of the adjusting rod 505 to achieve a change in the ventilation volume.

[0035] In addition, there are multiple air duct assemblies 5, and the outer curtain wall 4 is arranged between two air duct assemblies 5, a vertical partition 504 is arranged inside the vertical air duct 501, and a spacer 512 is rotatably connected to the adjustment rod 505, and the spacer 512 is located between the two inner curtain walls 7. The spacer 512 is arranged to provide installation intervals for the inner curtain wall 7, and the spacer 512 is arranged to divide the flow air cavity into multiple small spaces of the same size, because in the small space, the air will be divided, reducing the mutual transfer of heat, avoiding the overall expansion damage of the curtain wall caused by the overall overheating of the flow air cavity, and the spacer 512 used will divide the heat accordingly, even if it is overheated, it is a small space that is overheated, not the whole process, so as to protect the curtain wall.

[0036] In addition, the moving part includes a power crank 601, one end of which is rotatably connected to the upper wall 1, and the other end of the power crank 601 is connected to a driving part, which is installed inside the lower wall 2. A push rod 602 is rotatably connected to the power crank 601, and a flow-pushing plate 603 is rotatably connected to the right end of the push rod 602, and the flow-pushing plate 603 is slidably connected inside the flow air cavity. The driving part controls the rotation of the power crank 601, and then pulls the push rod 602 to pull left and right in a circular motion. At this time, the flow-pushing plate 603 will realize a reciprocating cycle, and then drive the airflow inside the flow air cavity to move left quickly, similar to the "exhaust mechanism", and the push of the flow-pushing plate 603 is used to realize the overall air push of the flow air cavity, thereby improving the overall ventilation effect of the curtain wall.

[0037] It is worth noting that there are multiple push flow plates 603, and the multiple push flow plates 603 are all arranged inside the flow air cavity. The multiple push flow plates 603 are connected by connecting gear rods 606, and the connecting gear rods 606 are slidably connected to the spacer 512. The connecting gear rods 606 are located inside the spacer 512 and mesh with automatic gears 607, and the automatic gears 607 are installed on the adjustment rod 505. Two vents are provided on the push flow plate 603, and a guide rod 605 is slidably connected to the push flow plate 603. One end of the guide rod 605 is connected to a sealing plate 604, and the sealing plate 604 is covered on the vents. The spacer 512 is provided with a wind slot 608. There are multiple push plates 603, and the connection of the connecting gear rod 606 is used to realize the synchronous pushing of the multiple push plates 603. Under the push of the multiple groups of push plates 603, the airflow between the push plates 603 and the spacer sleeve 512 will be discharged from the opening position of the air duct assembly 5. Because the multiple push plates 603 will form a similar "closed area", the airflow will enter the right side wind slot 502 of the second vertical air duct 501. Because the vertical partition plate 504 is set inside the vertical air duct 501, the interior is divided into two spaces on the left and right sides. The airflow will enter the interior of the vertical air duct 501 from the side wind slot 502 to achieve external discharge. And under the push of the flow-pushing plate 603, the connecting gear rod 606 will be driven to move horizontally, and then the meshing of the teeth will drive the automatic gear 607 to rotate, and the rotation of the automatic gear 607 will drive the rotation of the adjusting rod 505, and then automatically control the opening size of the air duct assembly 5, so that when exhausting, the opening of the vertical air duct 501 becomes larger, the discharge volume of hot air is increased, and the repeated absorption of exhaust gas is reduced during "inhalation", thereby avoiding repeated absorption of heat.

[0038] It is worth mentioning that the cleaning part includes a core rod 609, which is installed inside the flow-pushing plate 603. A coil 610 is wound around the surface of the core rod 609. A power module is provided in the upper wall 1 or the lower wall 2. The coil 610 is electrically connected to the power module. One end of the core rod 609 is connected to a magnetic sheet 611, and one side of the magnetic sheet 611 is magnetically connected to a magnetic sheet 613. A hook frame 614 is installed on the magnetic sheet 613, and the hook frame 614 is slidably connected to the connecting piece 3. A cleaning frame 612 is installed on the hook frame 614, and the cleaning frame 612 abuts against the surface of the outer curtain wall 4. An inner frame 615 is installed on the flow-pushing plate 603, and the surface of the inner frame 615 abuts against the surface of the inner curtain wall 7. Considering that it is difficult to clean the dust attached to the surface of the double-layer curtain wall after installation, a cleaning piece is set up. By pressing the power button of the power module, the core rod 609 is magnetized by the winding of the coil 610, and then the magnetic force will be transmitted to the magnetic sheet 611. Then the magnetic sheet 611 and the magnetic suction sheet 613 will produce magnetic attraction. Then, with the reciprocating motion of the push flow plate 603, the hook frame 614 and the cleaning frame 612 on the magnetic suction sheet 613 will be driven to move synchronously through the principle of electromagnetism, and the inner frame 615 is connected to the inside of the flow air cavity on the push flow plate 603. Therefore, at this time, with the movement of the push flow plate 603, the cleaning frame 612 and the inner frame 615 will be driven to scrape the dust on the surface of the outer curtain wall 4 and the inner curtain wall 7, thereby realizing automatic curtain wall cleaning.

[0039] Working principle, first of all, when the entire curtain wall is in use, when sunlight shines on the outer curtain wall 4, the internal air of the flow air cavity will be heated up, and the flow air cavity is located between the outer curtain wall 4 and the inner curtain wall 7, so the heat will be radiated to the indoor space through the inner curtain wall 7, so the indoor temperature will also be affected by the air temperature of the flow air cavity, and if the indoor temperature is high, the threaded sleeve 506 with threaded connection can be controlled to move forward and backward by rotating the adjustment rod 505. When moving forward, the support rod 508 connected in a triangle will rotate, thereby driving the connecting plate 509 to move upward, and then driving the sliding rack 510 to move upward, and the sliding rack 510 will drive the teeth to mesh and rotate with multiple pinions 511, and the rotation of the pinion 511 will drive multiple louvers 503 to rotate, so the louvers 503 will be in an open state, if the threaded sleeve 506 rotates in the opposite direction, the sliding rack 510 will be moved downward by gravity, thereby driving the pinion 511 to rotate in the opposite direction, thereby driving the louver 503 to close. Therefore, the operator can directly control the size of the opening of the external air duct assembly 5 according to the rotation of the adjustment rod 505 to achieve the change of ventilation volume. If it is hot in summer, it is necessary to ensure the high fluidity of the air in the flow cavity, otherwise the summer sun will continuously irradiate and heat the internal air of the flow cavity, which will cause the radiation entering the room to increase in temperature. Therefore, at this time, the rotation of the driving member is directly controlled, and the driving member is specifically an electric component, and a motor can also be used. Any component that controls the power crank 601 to rotate, and the rotation of the power crank 601 will pull the push rod 602 to pull left and right in a cycle, thereby driving the flow-pushing plate 603 to perform a left and right cycle. When the flow-pushing plate 603 moves to the left ( Figure 1 The airflow in the flow cavity will move rapidly to the left through the entire closed structure plate body. If the push plate 603 moves to the right ( Figure 1), due to inertia, the control guide rod 605 will slide on the pushing plate 603, thereby driving the sealing plate 604 away from the pushing plate 603, creating a gap. At this time, the airflow on the right side will flow from the open groove of the pushing plate 603 to the left side of the pushing plate 603. When the pushing plate 603 moves to the left again, it will first push the pushing plate 603. Then, due to inertia and the squeezing of the air in front, the control sealing plate 604 will abut against the position of the open groove, forming a closed plate body of the pushing plate 603 to maximize the control of the airflow push. At this time, the airflow will pass through the wind groove 608 opened on the spacer sleeve 512, and enter another section of the flow air cavity, and repeat this process, and finally transmit the airflow to the inside of the leftmost air duct assembly 5 to realize airflow discharge. Therefore, the formation mode of the overall principle is similar to "piston movement". When the airflow enters through the position of the vertical air duct 501, it will enter the flow cavity through the open space of the side wind slot 502. Then, with the movement of the "piston", the fluidity inside the flow cavity is improved, thereby ensuring the overall ventilation effect of the curtain wall and the radiation control of the indoor temperature by operators in different environments. The entire push flow plate 603 is set in multiple, and the connection of the connecting gear rod 606 is used to realize the synchronous promotion of multiple push flow plates 603. Under the promotion of multiple groups of push flow plates 603, the airflow between the push flow plate 603 and the spacer 512 will be discharged from the opening position of the air duct assembly 5. Because multiple push flow plates 603 will form a similar "closed interval" at this time, the airflow will enter the right side wind slot 502 position of the second vertical air duct 501. Because the vertical partition 504 is set inside the vertical air duct 501, the interior is divided into two spaces on the left and right sides. The promotion of the airflow will enter the interior of the vertical air duct 501 from the position of the side wind slot 502 to achieve external discharge. And under the push of the push plate 603, the connecting gear rod 606 will be driven to move horizontally, and then the meshing of the teeth will drive the rotation of the automatic gear 607, and the rotation of the automatic gear 607 will drive the rotation of the adjustment rod 505, and then automatically control the opening size of the air duct assembly 5, so that when exhausting, the opening of the vertical air duct 501 becomes larger, the displacement of hot air is increased, and the repeated absorption of the exhaust gas is reduced during "inhalation", because "when inhaling", the automatic gear 607 rotates in the opposite direction, which will control the opening of the vertical air duct 501, that is, the opening of the louver 503 is reduced, so the ventilation assembly 6 will reduce the hot air flow just discharged from the outside during "inhalation", realize the efficient self-drainage of the flow air cavity, and realize the ventilation and cooling of the curtain wall. Of course, the whole scheme can also directly adopt a push plate 603 to realize the overall flow exhaust of the flow air cavity, and the actual scheme can be selected according to the user's choice.Because it is difficult to clean the dust attached to the surface of the double-layer curtain wall after installation, a cleaning piece is set up, and the cleaning piece adopts the principle of electromagnetism. Because the traditional magnetic strip will be demagnetized after long-term use, electromagnetism will generate magnetic force when electricity is turned on. At this time, press the power button of the power module, and use the winding of the coil 610 to magnetize the core rod 609, and then the magnetic force will be transmitted to the magnetic sheet 611, and then the magnetic sheet 611 and the magnetic suction sheet 613 will produce magnetic attraction. Then, with the reciprocating motion of the push plate 603, it will drive the magnetic sheet 613 through the principle of electromagnetism. The hook frame 614 and the cleaning frame 612 on the suction piece 613 move synchronously, and the inner frame 615 is connected to the inside of the flow air cavity on the push flow plate 603. Therefore, as the push flow plate 603 moves, the cleaning frame 612 and the inner frame 615 will be driven to scrape dust off the surface of the outer curtain wall 4 and the inner curtain wall 7. Because the inside of the flow air cavity is air from the outside, the surface of the outer curtain wall 4 and the inner curtain wall 7 will inevitably have dust attached with long-term use, which is not easy to clean. Therefore, the magnetic attraction is used to realize an optional way to perform cleaning operations, which is simple, convenient and fast.
