Description
Technical Field
[0001] This application relates to the field of green building technology, and in particular to an energy-saving and heat-insulating structure for building roofs. Background Technology
[0002] In the field of building engineering, the roof, as an important component of the building envelope, directly affects the building's energy consumption and indoor thermal comfort due to its thermal insulation performance. With the escalating global energy crisis and the popularization of energy conservation and environmental protection concepts, energy-saving and thermal insulation design of building roofs has become a key research area in the industry.
[0003] Existing building roof energy-saving insulation structures mostly rely on fixed insulation layers to achieve their insulation function. This method is limited, passively blocking heat transfer and unable to actively collect and utilize solar energy. Fixed insulation layers are constantly exposed to the external environment, making them susceptible to erosion from wind, rain, and ultraviolet radiation, leading to a gradual decline in insulation performance and a short lifespan. Some roof structures attempting to integrate solar collectors often have fixed-installation collectors that cannot be flexibly retracted. In seasons when heat collection is not needed, this can exacerbate indoor temperature increases, thereby increasing air conditioning energy consumption. Furthermore, fixed collectors can affect the roof's drainage function and aesthetics. In existing solar collector roof structures, the connection between the collectors and the indoor heat conduction system is unreliable, resulting in significant heat loss during transfer and poor collection efficiency. In addition, the deployment and retraction of collectors largely depend on manual operation, resulting in low automation, cumbersome operation, and poor safety. Summary of the Invention

[0017] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.
[0018] This application discloses an energy-saving and heat-insulating structure for building roofs. For example... Figure 1-5As shown, the structure includes a ridge 1, a slope 2, ridge tiles 3, and a tile layer 4. A retractable collection mechanism is located on the slope 2 near the ridge 1. The ridge tiles 3 have rectangular notches 5 for the collection mechanism to extend out of and into. The collection mechanism includes a base 6 fixed to the slope 2 with screws. A movable storage component, including a bracket 7, is located on the base 6. A push rod motor 19 is fixed to both sides of the base 6 with mounting screws.

A power supply electrically connected to the push rod motor 19 is snapped onto the base 6. Both the power supply and the push rod motor 19 are existing technologies. A take-up roller 8 is rotatably connected to the bracket 7. The take-up roller 8 is prior art. The bracket 7 is equipped with an interference fit and a bearing at the end of the take-up roller 8. One end of the take-up roller 8 extends outside the bearing. A motor for driving the rotation of the take-up roller 8 is fixed to the bracket 7 by mounting bolts. The output shaft of the motor is connected to one end of the take-up roller 8 by meshing gears. A collection layer 9 is wound on the take-up roller 8. The collection layer 9 has a hollow structure. An airbag belt 10 is provided on the edge of the collection layer 9. The airbag belt 10 is prior art. An air pump connected to the airbag belt 10 via an air tube is fixed to the bracket 7 by screws. When the airbag belt 10 is inflated, the collection layer 9 will be supported into a rectangular structure. The collection layer 9 includes a surface layer 11 and a bottom layer 12. The surface layer 11 includes multiple collection units 13, which are arranged in an array and sequentially. The side of the collection unit 13 away from the bottom layer 12 is arc-shaped. An airbag tube 20 for supporting the collection unit 13 in an arc-shaped structure is glued to the surface layer 11. The airbag tube 20 is existing technology. There are multiple airbag tubes 20, which are arranged along the centerline of each collection unit 13. An elastic mesh is glued to the outside of the airbag tube 20. The airbag tube 20 is connected to the airbag belt 10. A drive wheel 14 is glued to one end of the collection layer 9. When the storage component moves upward, the collection layer 9 will extend along the slope 2 under the gravity of the drive wheel 14. A heat conduction cavity 15 is set inside the building wall. The collection layer 9 is connected to the heat conduction cavity 15 through a pipeline. When the collection layer 9 unfolds on the slope 2 to collect heat, the heat will be transferred to the room through the pipeline. A heat dissipation plate 34 is placed inside the heat conduction cavity 15. The heat dissipation plate 34 is made of metal. An opening 35 connected to the heat conduction cavity 15 is also provided on the wall.
[0019] In one embodiment, according to the appendix Figure 2 As shown, the bracket 7 is provided with a top plate 16 that mates with the notch groove 5. A sealing strip 17 is glued to the edge of the top plate 16. The ridge tile 3 is provided with a groove that mates with the sealing strip 17. A retractable shielding strip 18 is screwed to the top plate 16 near its three sides. A spool for winding the shielding strip 18 is provided at the end of the shielding strip 18 away from the top plate 16. A buckle for engaging the spool is screwed to the top plate 16. The shielding strip 18 is located on the side of the top plate 16 closest to the slope 2.
[0020] In one embodiment, according to the appendix Figure 2 and 7 As shown, the drive wheel 14 includes a wheel frame 21 connected to the collection layer 9. The wheel frame 21 has multiple wheel grooves evenly spaced along its length. Each wheel groove contains a wheel 22. The axle 23 of each wheel 22 is bolted to a wheel rod 24. The wheel groove contains a sliding groove 25 for the wheel rod 24 to move vertically. Both ends of the sliding groove 25 are fitted with compression springs 26 connected to the wheel rod 24.
[0021] In one embodiment, according to the appendix Figure 2 , 4 As shown in Figure 6, the pipeline includes a clamping pipe 27 communicating with the collection layer 9. A heat-conducting pipe for communicating with the heat-conducting cavity 15 is provided on the slope 2. The end of the heat-conducting pipe is provided with a connecting part 28 that is detachably connected to the clamping pipe 27. One end of the collection layer 9 is fixed to the winding roller 8. The winding roller 8 is provided with a placement groove 29. There are multiple placement grooves 29, which are evenly spaced along the length of the winding roller 8. Each placement groove 29 is provided with a clamping pipe 27. A protective sleeve 30 is fitted on the end of the clamping pipe 27 near the collection layer 9. A spring 31 is fixed in the placement groove 29 with screws. When the collection layer 9 is completely removed from the winding roller 8, the clamping pipe 27 moves under the action of the spring 31 and communicates with the connecting part 28. The connecting part 28 is connected to the heat-conducting pipe through a flexible corrugated pipe. A vertical rod 32 is fixed on the bracket 7 with screws. A shaft 33 with an integral structure is provided on both sides of the connecting part 28. The vertical rod 32 and the shaft 33 are connected by a torsion spring. When the collecting layer 9 is gradually moved off the winding roller 8, the connecting part 28 always fits the collecting layer 9 under the action of the torsion spring.
[0022] The implementation principle of the building roof energy-saving and heat-insulating structure in this application embodiment is as follows: When heat needs to be collected, the push rod motor 19 is started, the power supply is provided to the push rod motor 19, the output shaft of the push rod motor 19 extends, pushes the bracket 7 to move upward, and drives the entire storage component to move out from the notch 5 until the central axis of the winding roller 8 is flush with the ridge tile 3. At this time, the push rod motor 19 is turned off; the shielding strip 18 moves with the top plate 16 to prevent debris from entering.
[0023] The motor is started, driving the take-up roller 8 to rotate and gradually releasing the collection layer 9. Under the weight of the drive wheel 14, the collection layer 9 extends downwards along the slope 2. During the unfolding process, the wheel 22 of the drive wheel 14 contacts the slope 2. When the slope 2 is uneven, the wheel 22 moves up and down within the groove 25 via the wheel rod 24, causing the compression spring 26 to elastically deform, ensuring that the wheel 22 always remains in contact with the slope 2, thereby smoothly unfolding the collection layer 9. The connecting part 28 remains in contact with the collection layer 9 under the elastic action of the torsion spring.
[0024] Once the collection layer 9 is fully deployed, the motor is turned off and the air pump is started. The air pump inflates the airbag belt 10 through the air tube. After the airbag belt 10 is inflated, it drives the airbag tube 20 connected to it to inflate synchronously. Under the constraint of the elastic net, the airbag tube 20 supports the collection layer 9 into a rectangular structure and keeps each collection unit 13 in an arc shape.
[0025] After the collection layer 9 is unfolded, the arc-shaped collection unit 13 collects solar energy, and the heat gathers in the hollow collection layer 9. After the collection layer 9 is fully unfolded, the retaining pipe 27 pops out under the elastic force of the spring 31 and connects with the connecting part 28. The heat in the collection layer 9 enters the heat conduction cavity 15 through the retaining pipe 27, the connecting part 28, the corrugated pipe and the heat conduction pipe. The heat dissipation plate 34 in the heat conduction cavity 15 dissipates the heat into the room.
[0026] 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.
