Description

Technical Field

[0001] The present invention relates to the technical field of glass curtain walls, in particular to a heat-insulating glass curtain wall. Background Art

[0002] Glass curtain wall is a type of building exterior wall structure composed of glass panels and supporting structures, installed on the outside of the building for enclosure and decoration.

[0003] Existing devices of this type suffer from unsatisfactory noise isolation. For example, Chinese patent publication number "CN118309205A" discloses an energy-saving glass curtain wall. Although this device is optimized for energy conservation, the glass component of the device contains distilled water. The sound insulation effect of water has obvious limitations due to its physical properties and frequency response. As a single uniform medium, it mainly absorbs sound wave energy through viscous loss and heat conduction, but lacks a solid interface reflection mechanism. An extremely thick water layer is required for effective sound insulation. In addition, the liquid fluidity easily transmits low-frequency vibrations. In terms of frequency response, high-frequency sound waves have strong penetration, and low frequencies are prone to resonance. It only has a certain absorption effect on medium-frequency noise. Therefore, the sound insulation effect of this device is not ideal. Accordingly, the present application proposes a thermal insulation glass curtain wall. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a heat-insulating glass curtain wall.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A heat-insulating glass curtain wall comprises a longitudinal beam, a transverse beam, and a limiting plate.

The side wall of the cleaning part is provided with a force storage part and a transmission part, a temperature control part is provided below the ventilation part, and an expansion part is provided above the noise reduction part; A spring box is provided on one side of the longitudinal beam, and a connecting rod is provided on the side wall of the spring box. The connecting rod is divided into two parts. When the two parts of the connecting rod are engaged, power can be transmitted; A power plate is also provided inside the crossbeam, which drives the air circulation in the front glass through reciprocating motion, thereby reducing reverse heat transfer in the room; A telescopic rod is also provided on the crossbeam. When the output rod of the telescopic rod is extended, the temperature control is turned on, and when the output rod of the telescopic rod is retracted, the temperature control is closed. A thermosensitive liquid is provided inside the telescopic rod. The volume of the thermosensitive liquid expands and contracts with heat and cold, causing the output rod of the telescopic rod to extend or retract, thereby driving the limit plate to move upward or downward.

[0006] The temperature control unit is used to turn on and off the ventilation unit. When the temperature control unit is turned on, the ventilation unit is turned on. When the temperature control unit is turned off, the ventilation unit is turned off.

[0007] Preferably, a handle is provided inside the crossbeam, and a transmission gear and a transmission rack are provided inside the crossbeam. The handle is used to drive the unfolding member, and then drive the noise reduction part to unfold. The handle transmits power to the unfolding member, and the transmission gear drives the transmission rack to move toward each other, thereby realizing the unfolding of the noise reduction part.

[0008] Preferably, the cleaning part is driven by a clockwork box, which transmits power through the spring inside it to drive the transmission part to rotate. The clockwork box accumulates energy through the force storage part on its side wall. A trigger box and a separation column are also provided on the side wall of the clockwork box. The trigger box presses down with its own weight, thereby lifting the separation column, causing the two parts of the connecting rod to engage and transmit power, thereby realizing the operation of the cleaning part.

[0009] Preferably, a sound insulation grille is provided between the two crossbeams, the sound insulation grille is used to form a cavity, and a handle is provided at the rear of the crossbeam, the handle is used to drive the noise reduction part.

[0010] Preferably, the noise reduction portion is extended between the front glass and the rear glass.

[0011] Preferably, the noise reduction portion divides the space between the front glass and the rear glass into a plurality of cavities.

[0012] Preferably, a trigger box is slidably provided on the outer surface of the clockwork box.

[0013] Preferably, a propeller is provided on the mainspring barrel, and the propeller is used to provide power for the mainspring barrel.

[0014] Preferably, a spring rod is further provided on the clockwork box.

[0015] The present invention has the following beneficial effects: 1. By setting up a ventilation part, when the device is in use, the ventilation part can ventilate the air inside the front glass, allowing external air to flow in and internal air to flow out. This can prevent the air in the front glass from being heated all the time, thereby causing the temperature in the front glass to be too high. As a result, when the temperature is high, the low temperature in the room will migrate to the front glass, thereby affecting the cooling effect. In cold weather, the air in the front glass no longer flows, allowing sunlight to always heat the front glass, which can reduce indoor heat loss.

[0016] 2. By setting up the cleaning part, the surface of the front glass can be cleaned by the cleaning rod when the device is in use, thereby avoiding the unsafe problem caused by manual cleaning at high places. When in use, the power of the spring is transmitted to the reciprocating screw by the bevel gear. Due to the structure of the reciprocating screw, the cleaning rod will move toward one end of the front glass, during which time the dust on the outer surface of the front glass will be wiped off.

[0017] 3. By setting up the noise reduction part, the sound insulation grille can be opened inside the device when it is in use. Multiple sound insulation grilles can divide the interior of the device to form multiple cavities. When noise is transmitted into the device, the multiple cavities will dissipate the energy of the noise, making the final sound smaller, thereby achieving the purpose of noise reduction.

[0018] 4. By setting up the rear glass, this device takes into account both sound insulation and thermal insulation effects. When the sound is transmitted to the rear glass of this device, because the interior is a vacuum, the sound can only be transmitted from the rear glass body to the room, which brings better sound insulation effect to the device. At the same time, the external temperature will also be isolated by the vacuum, so that the device can achieve better thermal insulation effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Embodiment 1: A thermal insulation glass curtain wall includes a longitudinal beam 2, a transverse beam 3, and a limiting plate 11. The outer surface of the longitudinal beam 2 is provided with a cleaning portion, the interior of the transverse beam 3 is provided with a ventilation portion, the front part of the transverse beam 3 is provided with a front glass 1, the rear part of the transverse beam 3 is provided with a rear glass 26, and a noise reduction portion is provided between the front glass 1 and the rear glass 26.

[0023] A sound insulation grille 29 is provided between the two cross beams 3, and the sound insulation grille 29 is used to form a cavity. A handle 28 is provided behind the cross beam 3, and the handle 28 is used to drive the noise reduction part. The noise reduction part is deployed between the front glass 1 and the rear glass 26, and the noise reduction part divides the space between the front glass 1 and the rear glass 26 into multiple cavities.

[0024] A handle 28 is provided inside the crossbeam 3, and a transmission gear 31 and a transmission rack 32 are provided inside the crossbeam 3. The handle 28 is used to drive the unfolding part, and then drive the noise reduction part to unfold. The handle 28 transmits power to the unfolding part, and the transmission gear 31 drives the transmission rack 32 to move toward each other, thereby realizing the unfolding of the noise reduction part.

[0025] The noise reduction part is used to reduce noise. The side wall of the cleaning part is provided with a power storage part and a transmission part. A temperature control part is provided below the ventilation part, and an expansion part is provided above the noise reduction part.

[0026] In the present application, the noise reduction part may specifically be composed of the following structures: a sound insulation grille 29 , a handle 28 , a transmission shaft 30 , a transmission gear 31 , and a transmission rack 32 .

[0027] The unfolding member includes a handle 28 , a transmission shaft 30 , a transmission gear 31 , and a transmission rack 32 .

[0028] The sound insulation grille 29 is slidably connected between the front glass 1 and the rear glass 26. There are multiple sound insulation grilles 29, which are connected by steel wire ropes of equal length. The handle 28 is fixedly connected to the transmission shaft 30 and is rotatably connected to the crossbeam 3. The transmission shaft 30 and the transmission gear 31 are driven by multiple bevel gears. The transmission rack 32 is meshed with the transmission gear 31 through the cylindrical gear at its lower end. For details, please refer to Figure 7 .

[0029] In this embodiment, when the handle 28 is shaken, the bevel gear at the front end of the handle 28 transmits power to the transmission shaft 30. The transmission shaft 30 is connected to the internal rotation of the crossbeam 3 and has bevel gears at both ends. The power of the handle 28 is transmitted from the transmission shaft 30 to the transmission gear 31. Figure 7 There is a cylindrical gear at the lower end of the transmission gear 31, which meshes with the transmission rack 32, so the transmission rack 32 will move due to the rotation of the transmission rack 31, and the transmission rack 32 is fixedly connected to the first sound insulation grille 29, and the sound insulation grilles 29 are connected by steel wire ropes, so the sound insulation grilles 29 will be pulled toward the middle. During this period, the sound insulation grilles 29 will unfold to form a cavity between the front glass 1 and the rear glass 26.

[0030] When sound waves enter a cavity, they undergo multiple reflections, interference, and absorption. Firstly, due to different reflection paths, the peaks and troughs of some waves overlap or cancel each other during reflection from the cavity walls, causing interference and reducing the energy of the sound waves. Secondly, the air and wall materials within the cavity absorb the sound waves, causing the energy of the sound waves to be converted into other forms of energy, such as heat, and thus lost. These factors work together to effectively weaken the intensity of the sound waves, thereby achieving the desired noise reduction effect.

[0031] The sound insulation grille 29 is perpendicular to the rear glass 26 and is relatively thin, so when it is deployed, it will not affect the use of the rear glass 26 and the front glass 1.

[0032] Embodiment 2: The cleaning part is used to clean the front glass 1. The cleaning part is driven by the clockwork box 16. The clockwork box 16 transmits power through the clockwork inside it to drive the transmission part to rotate. The clockwork box 16 accumulates energy through the power storage part on its side wall. The side wall of the clockwork box 16 is also provided with a trigger box 20 and a separation column 24. The trigger box 20 presses down with its own weight, thereby lifting the separation column 24, so that the two parts of the connecting rod 19 engage and transmit power, thereby realizing the operation of the cleaning part. The ventilation part is used to balance the temperature of the front glass 1 and the outside world.

[0033] In the present application, the cleaning portion may specifically comprise the following structural components: a force storage member, a transmission member, a cleaning rod 14 , a trigger box 20 , a spring rod 21 , a separation column 24 , and a trigger gear 25 .

[0034] The force storage component is composed of the following structures: a propeller 15 , a clockwork barrel 16 , a check pawl 22 , a ratchet 23 , and a reciprocating screw 17 .

[0035] The transmission part is composed of the following structures: a reciprocating screw 17, a rotating gear 18, and a connecting rod 19.

[0036] The cleaning rod 14 is threadedly connected to the reciprocating screw 17 and is attached to the outer surface of the front glass 1. The propeller 15 cooperates with the spring inside the barrel 16. The reciprocating screw 17 is meshed with the rotating gear 18 through the bevel gear at one end. The rotating gear 18 is rotatably connected to the propeller 15. The connecting rod 19 is divided into two parts, one of which is connected to the barrel 16 for sliding and limiting, and the other is fixedly connected to the rotating gear 18. A separation column 24 is provided between them. The lower end of the separation column 24 is conical. The cone overcomes the force of the spring on the separation column 24 to separate the two parts. The separation column 24 is connected to the barrel 16 for sliding and limiting, and the trigger gear 25 connects the separation column 24 and the trigger box 20 through a rack. For details, please refer to Figure 8-9 as well as Figure 3 .

[0037] The cleaning part can be started only when it rains. Normally, the wind blows the propeller 15 to provide energy for the spring in the spring box 16. When energy is provided, the wind blows the propeller 15 to rotate. Since the propeller 15 cooperates with the spring, it can drive the spring to store energy.

[0038] refer to Figure 9 The separation column 24 separates the connecting rod 19 so that the two parts cannot be merged together, that is, the teeth on the connecting rod 19 cannot engage. It should be noted that the separation column 24 does not contact the teeth on the connecting rod 19. There is a spring for resetting inside the spring rod 21, and the spring rod 21 is connected to the trigger box 20, so that the trigger box 20 can be reset after being pressed down by rainwater.

[0039] When the weather meets the triggering condition of the cleaning part, that is, when it rains, the interior of the trigger box 20 will be filled with water due to the rain. At this time, the weight of the trigger box 20 can overcome the spring force of the spring rod 21, causing it to press downward due to the effect of gravity. Figure 9When the trigger box 20 is pressed downward, the rack at its lower end is also pressed downward. The rack is slidably connected to the spring box 16. The rack then transmits power to the rack connected to the separation column 24 through the trigger gear 25. The rack lifts the separation column 24 upward, causing it to break away from the contact with the connecting rod 19. Then, under the action of the spring on the connecting rod 19, the two parts of the connecting rod 19 are connected, and the teeth on them are engaged together, thereby transmitting the power of the spring to the rotating gear 18. Then, the rotating gear 18 transmits power to the reciprocating screw 17, which drives the cleaning rod 14 to move back and forth, during which the dust on the front glass 1 is wiped off. Since the cleaning part can only be started when there is water inside it, that is, on rainy days, the cleaning part can enhance the cleaning effect with the help of rainwater.

[0040] It should be noted that the separation column 24 is rotatably connected to the non-return pawl 22 through a telescopic rod 35. When the ratchet 23 rotates, that is, when the spring accumulates force, the inclined portion on the non-return pawl 22 can be lifted by the ratchet 23. The principle is the same as that of the ratchet and pawl.

[0041] When the cleaning portion is activated, the separation column 24 is lifted upward, thereby driving the anti-return pawl 22 to rotate in a direction away from the ratchet 23 , that is, the ratchet 23 is separated from the anti-return pawl 22 .

[0042] Embodiment 3: A spring box 16 is provided on one side of the longitudinal beam 2, and a connecting rod 19 is also provided on the side wall of the spring box 16. The connecting rod 19 is divided into two parts. When the two parts of the connecting rod 19 are engaged, power can be transmitted. A power plate 6 is also provided inside the crossbeam 3. The power plate 6 drives the air circulation in the front glass 1 through reciprocating motion, thereby reducing the reverse heat transfer in the room.

[0043] A telescopic rod 8 is also provided on the crossbeam 3. When the output rod of the telescopic rod 8 is extended, the temperature control is turned on, and when the output rod of the telescopic rod 8 is retracted, the temperature control is closed. A thermosensitive liquid is provided inside the telescopic rod 8. The volume of the thermosensitive liquid expands and contracts with heat, causing the output rod of the telescopic rod 8 to extend or retract, thereby driving the limit plate 11 to move upward or downward.

[0044] The temperature control unit is used to turn the ventilation unit on and off. When the temperature control unit is turned on, the ventilation unit is turned on. When the temperature control unit is turned off, the ventilation unit is turned off. A trigger box 20 is slidably provided on the outer surface of the barrel 16. The barrel 16 is provided with a propeller 15 for providing power to the barrel. The barrel 16 is also provided with a spring rod 21.

[0045] In the present application, the ventilation part can be specifically composed of the following structures: power plate 6, upper sealing membrane 33, lower sealing membrane 34, telescopic rod 8, lifting rack 9, lifting gear 10, limit plate 11, guide rod 12, opening spring 13, cleaning rod 14, upper sealing membrane 33, and lower sealing membrane 34.

[0046] The power plate 6 is mounted on the upper crossbeam 3 and is in sealed, sliding connection with the interior space of the crossbeam 3. One end of the upper and lower sealing membranes 33 and 34 are fixedly connected to the crossbeam 3. Each of the upper and lower sealing membranes 33 and 34 has a hole for air venting below. The limit plate 11 is pressed against the notch at the bottom of the front glass 1 by the opening spring 13, covering the notch. Power is transmitted between the lifting rack 9 and the limit plate 11 via the lifting gear 10, which is rotationally connected to the crossbeam 3. The telescopic rod 8 and the lifting rack 9 are also fixedly connected to the crossbeam 3.

[0047] The power plate 6 will move due to the wind, refer to Figure 2 The telescopic rod 8 is filled with a thermosensitive liquid that expands when heated and contracts when cooled. When heated, the thermosensitive liquid expands, pushing the output rod of the telescopic rod 8 upward, which in turn drives the lifting rack 9 upward. The movement of the lifting rack 9 rotates the lifting gear 10, which in turn pulls the limit plate 11 downward, overcoming the force of the opening spring 13. This opens the gap above the limit plate 11, connecting the interior of the front glass 1 with the exterior space.

[0048] When the wind blows the power plate 6, it will move left and right. Figure 10 In the crossbeam 3 , the power plate 6 is similar to a piston, the gap below the upper sealing film 33 is connected to the external space, and the gap below the lower sealing film 34 is connected to the interior of the crossbeam 3 and the interior of the front glass 1 .

[0049] When the temperature is high, the power plate 6 moves. Since it cooperates with the crossbeam 3 like a piston, the outside air will be sucked into the front glass 1 and then ejected from the bottom of the lower sealing film 34. When the power plate 6 moves, this part of the air will be ejected from the bottom of the upper sealing film 33 to the outside, thereby completing the ventilation of the inside of the front glass 1.

[0050] Since ventilation dissipates heat for the front glass 1, this can reduce the temperature of the front glass 1. When the temperature is high, the temperature of the front glass 1 is relatively low, so the effect of absorbing low temperatures from the room can be reduced. When used in conjunction with the rear glass 26, a better effect of isolating high temperatures can be achieved.

[0051] When the temperature is low, the thermosensitive liquid contracts, driving the output rod of the telescopic rod 8 downward. The lifting gear 10 then moves downward, causing the limit plate 11 to move upward, blocking the hole in the limit plate 11 and thus sealing the connection between the interior and exterior of the front glass 1. This allows sunlight to heat the air inside for a long time, isolating the indoor and outdoor spaces with a hot air barrier, thereby reducing heat loss.

[0052] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
