Description

Technical Field

[0001] The present invention belongs to the technical field of building energy conservation, and particularly relates to a building heat insulation and energy-saving device based on low-emissivity glass. Background Art

[0002] In the field of modern architecture, energy conservation and environmental protection have become important development trends. Especially in building heat insulation design, it is of great significance for reducing energy consumption and improving indoor comfort. As an important part of the building's outer envelope structure, glass plays an irreplaceable role in lighting and vision. However, the traditional glass has a high heat conduction performance, which easily leads to heat transfer through the glass, thus increasing the cooling or heating energy consumption of the building. To solve this problem, low-emissivity glass (Low-E glass) has emerged. Its heat radiation rate is effectively reduced through special coating technology, significantly improving the building's heat insulation performance.

[0003] However, although low-emissivity glass has improved the building's energy-saving effect to a certain extent, there are still some deficiencies in practical applications. For example, using low-emissivity glass alone often fails to meet the heat insulation requirements under complex climate conditions. Especially in environments with large temperature differences or strong sunlight, its heat insulation performance may not achieve the ideal effect. In addition, there is a lack of efficient heat insulation devices for supporting the use of low-emissivity glass in the existing technology, resulting in limited overall energy-saving effect. At the same time, some building heat insulation devices are inconvenient in installation and maintenance, increasing the use cost and technical difficulty. Therefore, how to give full play to the advantages of low-emissivity glass and combine innovative heat insulation and energy-saving designs has become an urgent technical problem to be solved in the current building energy conservation field.

[0004] In view of the above problems, developing a building heat insulation and energy-saving device based on low-emissivity glass, which can further optimize the building's heat insulation performance, improve energy utilization efficiency, and at the same time take into account the installation convenience and economy, has important practical significance and broad application prospects.

Specific embodiments

[0024] The present invention provides a building heat insulation and energy saving device based on low-emissivity glass, and its specific embodiments are described in detail as follows in conjunction with the attached Figure 1 to the attached Figure 3 for detailed description. As Figure 1 shown, the device mainly includes core components such as a frame body 1, a low-emissivity glass assembly 2, an adjustable sunshade mechanism, a heat-reflective assembly, and a heat collection box body 14. The connection relationship and function realization among the components are reflected through specific structural designs, which will be described one by one below.

[0025] The frame body 1 serves as the main body structure of the entire device and is used to fix and support other components. A low-emissivity glass assembly 2 is arranged inside the frame body 1, and the low-emissivity glass assembly 2 utilizes its excellent heat insulation performance to reduce heat transfer, thereby reducing the energy consumption inside the building. A guide rail groove 3 is fixedly arranged at the top of the frame body 1, and a sunshade 4 is slidably connected in the guide rail groove 3. The sunshade 4 is connected to the frame body 1 through an electric push rod 5. The sunshade 4 is a double-layer structure, with a highly reflective metal coating 6 on its inner layer and a weather-resistant transparent material 7 on its outer layer. When the external environmental temperature is relatively high, the electric push rod 5 drives the sunshade 4 to move horizontally along the guide rail groove 3 to adjust the sunshading area of the low-emissivity glass assembly 2. The highly reflective metal coating 6 of the sunshade 4 can effectively reflect solar radiation, while the weather-resistant transparent material 7 ensures the stability and anti-aging performance of the sunshade 4 during long-term use. This design not only realizes the dynamic regulation of solar radiation but also enhances the heat insulation effect of the overall device.

[0026] The heat-reflective assembly is located inside the frame body 1 and includes a plurality of arc-shaped reflectors 8. The arc-shaped reflectors 8 are rotatably connected to the inner walls on both sides of the frame body 1 through rotating shafts 9. As Figure 3As shown, the surface of the arc-shaped reflective sheet 8 is coated with a heat-reflective coating 10 to enhance its heat-reflective performance. The rotation angle of the arc-shaped reflective sheet 8 is limited by a limit block 11, which is arranged at intervals along the radial direction of the arc-shaped reflective sheet 8 and fixed on the inner wall of the frame body 1. The limit block 11 cooperates with the arc-shaped reflective sheet 8 to ensure that the arc-shaped reflective sheet 8 rotates within a certain range, thereby optimizing the heat-reflective effect. Guide wheels 12 that cooperate with the guide rail groove 3 are provided on both sides of the frame body 1, and a ratchet structure 13 with a unidirectional rotation function is provided on the guide wheel 12. The guide wheel 12 and the arc-shaped reflective sheet 8 are linked and connected through a transmission mechanism fixedly arranged on the outer surface of the frame body 1. When the sun visor 4 moves, the guide wheel 12 drives the arc-shaped reflective sheet 8 to rotate, thereby adjusting the heat-reflective angle according to actual needs. This linkage design makes full use of the dual effects of sunshade and reflection, and further improves the heat insulation performance of the device.

[0027] The heat collecting box 14 is fixedly connected to the bottom of the frame body 1. Figure 2 As shown, auxiliary wheels 15 that cooperate with the guide grooves 3 are rotatably provided on both sides of the collector box 14. The collector box 14, the auxiliary wheels 15, the guide wheels 12 and the arc-shaped reflector sheet 8 are all in the same plane to ensure the coordinated operation of the various components. A vent 16 is provided at the joint between the frame body 1 and the collector box 14, and a vertical guide plate 17 is fixedly connected to the collector box 14. A transversely arranged baffle 18 is slidably connected to the guide plate 17, and a sealing strip 19 is fixedly connected to one end of the baffle 18 facing the vent 16, and a connecting rod frame 20 is connected to the other end. Pins 21 are fixedly connected to both ends of the connecting rod frame 20, and cams 22 that are transmission-connected to the auxiliary wheels 15 are provided on both sides of the collector box 14. The cam 22 is provided with a spiral groove that cooperates with the pin 21. When the sun visor 4 moves, the sealing strip 19 at one end of the baffle 18 moves back and forth through the cooperation of the cam 22 and the pin 21, so that it fits or separates with the vent 16. This design can automatically adjust the ventilation state according to the ambient temperature, thereby further optimizing the energy saving effect.

[0028] An elastic sealing layer is fixedly connected to the baffle 18. The elastic sealing layer is hermetically connected to the inner wall of the heat collection box body 14. The elastic sealing layer is located between the guide plate 17 and the sealing strip 19, separating the internal space of the heat collection box body 14 into an independent chamber. The connecting rod frame 20 and the cam 22 are both located in the independent chamber to ensure the stability of their operation. Flow guiding channels are provided in both the sealing strip 19 and the baffle 18. A plurality of exhaust holes are provided on one side of the sealing strip 19 where the ventilation opening 16 is located. An air inlet pipe communicating with the flow guiding channel is fixedly connected to the connecting rod frame 20. An exhaust pipe is fixedly provided at the top of the heat collection box body 14. One-way valves are provided on both the air inlet pipe and the exhaust pipe. A dust-proof cover is fixedly connected to the top of the exhaust pipe. When the ambient temperature rises, the air in the heat collection box body 14 expands due to heat and is discharged through the exhaust pipe; when the ambient temperature drops, the external cold air enters the heat collection box body 14 through the air inlet pipe, thus realizing air circulation and heat management.

[0029] A detection box is fixedly connected to one side of the frame body 1 opposite to the ventilation opening 16. A temperature sensor is provided in the detection box for real-time monitoring of the ambient temperature. A transparent heat insulation film is fixedly provided at the joint of the detection box and the frame body 1 to reduce the influence of heat transfer on the temperature sensor. Electromagnetic clutches for drivingly connecting the auxiliary wheels 15 and the cam 22 are fixedly connected to both sides of the heat collection box body 14. The electromagnetic clutches can control the linkage state of the auxiliary wheels 15 and the cam 22 according to the signal of the temperature sensor, thus realizing intelligent adjustment. In addition, a maintenance door that can be closed or opened is provided on one side of the heat reflection assembly in the frame body 1, which is convenient for maintaining and overhauling the interior of the device.

[0030] The specific operation principle of the above device is as follows: When the external ambient temperature is relatively high, the electric push rod 5 drives the sunshade 4 to move horizontally along the guide rail groove 3. The highly reflective metal coating 6 of the sunshade 4 reflects solar radiation. At the same time, its movement triggers the one-way rotation of the guide wheel 12, and then drives the arc-shaped reflector 8 to rotate through the transmission mechanism, optimizing the heat reflection angle. The movement of the sunshade 4 also separates the sealing strip 19 at one end of the baffle 18 from the ventilation opening 16 through the cooperation of the cam 22 and the pin 21, thereby opening the ventilation channel and promoting air circulation to reduce the temperature inside the building. When the ambient temperature drops, the sunshade 4 retracts, the arc-shaped reflector 8 returns to its initial position, and the sealing strip 19 fits with the ventilation opening 16 again, closing the ventilation channel to maintain the temperature inside the building. The temperature sensor monitors the ambient temperature in real time and controls the linkage state of the auxiliary wheels 15 and the cam 22 through the electromagnetic clutch, thus realizing intelligent adjustment. The air circulation system in the heat collection box body 14 realizes heat management through the exhaust pipe and the air inlet pipe, further improving the energy-saving effect.

[0031] In summary, through a multi-level heat management mechanism, the present invention achieves high-efficiency heat insulation while possessing the characteristics of flexibility and intelligence, solving the deficiencies in the application of existing low-emissivity glass.

[0032] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
