The invention turns on the high-temperature energy storage board in the early morning and turns off the low-temperature energy storage board to allow sunlight to heat the low-temperature energy storage board, thereby maintaining a suitable room temperature, and turns off the high-temperature energy storage board and the compartment assembly in the afternoon, so that the high-temperature energy storage board absorbs excess heat and forms a heat insulation layer to prevent indoor overheating and maintain a stable temperature. The high-temperature energy storage board is turned off at night to release the stored heat, and the heat insulation layer isolates the low temperature outside to ensure that the indoor temperature is warm and stable. Therefore, through this series of adjustments, the system effectively adjusts the indoor temperature, improves living comfort, and at the same time achieves energy-saving effects and maintains the stability of ambient temperature.

[0003] The existing roof structure will be eroded by rainwater for a long time, which will lead to the failure of the roof waterproof layer. Water will penetrate into the roof, corroding structural materials such as wood or steel, making the roof gradually fragile, and may even cause collapse or large-scale damage. At the same time, rainwater leakage will make the room damp, causing the ceiling coating to fall off and the wall to mold, which will not only affect the appearance, but also breed mold and bacteria, endangering the health of residents. Building safety hazards, rainwater seeping into the concrete structure will cause the internal calcium hydroxide to be lost, accelerate the corrosion of steel bars, and affect the structural safety of the building. In addition, damp wires and pipes may cause short circuits or even fires.

[0005] The purpose of the present invention is to provide an assembled green building energy-saving roof structure to solve the technical problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions: an assembled green building energy-saving roof structure, comprising a roof body, an automatic protection structure is arranged on the top of the roof body, and drainage cleaning structures are symmetrically arranged on both sides of the automatic protection structure; The automatic protection structure includes a symmetrically arranged protective film, one end of which is connected to the outer ring of the rotating shaft, a protective cover is arranged on the outer ring of the rotating shaft, a through groove is symmetrically provided on the protective cover, the other end of the protective film passes through the through groove and is connected to a symmetrically arranged guide rail structure, the guide rail structure is a guide rail and a slider, the slider is slidably connected to the guide rail, the other end corner of the protective film is connected to the slider, the slider is connected to one end of the counterweight rope, the other end of the counterweight rope is connected to the counterweight block, and recovery devices are symmetrically arranged at both ends of the rotating shaft; The bottom of the roof body is connected to the outer frame block and the inner frame block, a card slot is formed between the outer frame block and the inner frame block, the inner frame block is provided with card holes at equal intervals, the card holes are in sliding contact with the pin block, one end of the pin block away from the card hole is in sliding contact with one side of the anti-slip block, the other side of the anti-slip block is in sliding contact with the bearing block, and the bearing block is connected to the inner frame block.

[0013] Compared with the prior art, the present invention has the following beneficial effects: (1) The automatic protection structure can effectively open the protective film on rainy days to prevent rainwater from washing the roof surface for a long time, causing gradual wear of the material. The acidic substances contained in the rainwater may cause chemical reactions in the roof material, further causing corrosion, discoloration or strength reduction of the material. At the same time, the automatic protection structure will retract the protective film after the rainy day to prevent ultraviolet rays from irradiating the protective film for a long time, causing photo-oxidation reaction of the material, causing it to gradually age, become brittle, or even crack, resulting in reduced rainproof performance and a significant shortening of the service life.

(2) Since the drainage channel drains water to both sides of the roof, the leaves may not be able to be discharged due to the low flow rate of rainwater. Long-term accumulation may cause drainage blockage and lose the drainage effect on both sides. Through the drainage cleaning structure, when rainwater flows into the water wheel, it will drive the cleaning scraper to rotate and push the collected leaves to the drainage channel, thereby realizing automatic cleaning and discharge of leaves, efficiently converting natural kinetic energy into required kinetic energy and reducing subsequent energy consumption; (3) The water flow direction is optimized through the water guide cover, and the water flow is concentrated and accurately impacted on the water wheel, thereby more efficiently converting the kinetic energy of the water into mechanical energy, driving the water wheel to rotate and achieving a stable transmission effect. In addition, the triangular plate-shaped guide scraper can more efficiently guide the flowing rainwater to accurately impact the water wheel, thereby improving the conversion efficiency of the kinetic energy of rainwater.

[0014] (4) The main roof body is connected to the wall through pin blocks, and the anti-drop blocks and bearing blocks are used to further prevent the pin blocks from falling off, making the installation and disassembly process of the main roof body simple and convenient, without the need for complex tools or techniques, and ensuring the stability and reliability of the connection between the main roof body and the wall. This connection method can significantly shorten the construction period, reduce the time and resource consumption of on-site disassembly and assembly, and facilitate reuse after subsequent disassembly, further meeting the requirements of green buildings for resource recycling.

DETAILED DESCRIPTION

[0017] 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.

[0018] See also Figure 1-9 The present invention provides a technical solution: an assembled green building energy-saving roof structure, including a roof body 1, an automatic protection structure 2 is arranged on the top of the roof body 1, and drainage cleaning structures 3 are symmetrically arranged on both sides of the automatic protection structure 2. The automatic protection structure 2 can effectively open the protective film 22 on rainy days to prevent rainwater from scouring the roof surface for a long time, causing gradual wear of the material, and the acidic substances that may be contained in the rainwater causing chemical reactions in the roof material, further causing corrosion, discoloration or strength reduction of the material. At the same time, after the rainy day is over, the automatic protection structure 2 will retract the protective film 22 to avoid long-term exposure of ultraviolet rays to the protective film 22, which will cause photo-oxidation reaction of the material, causing it to gradually age, become brittle, and even crack, thereby reducing the rainproof performance and the service life may be greatly shortened.

[0019] The automatic protection structure 2 includes a symmetrically arranged protection film 22, one end of which is connected to the outer ring of the rotating shaft 26, a protection cover 23 is arranged on the outer ring of the rotating shaft 26, and a through groove is symmetrically provided on the protection cover 23. By rotating the rotating shaft 26, the protection film 22 can be retracted into the protection cover 23 to prevent ultraviolet rays from causing the above-mentioned problems to the protection. The other end of the protection film 22 passes through the through groove and is connected to the symmetrically arranged guide rail structure 21. The guide rail structure 21 is a guide rail and a slider, and the slider is slidably connected to the guide rail. The other end corner of the protection film 22 is connected to the slider, and the slider is connected to one end of a counterweight rope 271, and the other end of the counterweight rope 271 is connected to a counterweight block 27. Recovering devices 25 are symmetrically arranged at both ends of the rotating shaft 26. Through the counterweight block 27 and the counterweight rope 271, the slider can be affected by gravity to cover the roof body 1 along the guide rail with the protection film 22; The bottom of the roof body 1 is connected to the outer frame block 41 and the inner frame block 42. A card slot is formed between the outer frame block 41 and the inner frame block 42. The inner frame block 42 has card holes equidistantly provided therein. The card holes are in sliding contact with the pin blocks 43. The end of the pin block 43 away from the card hole is in sliding contact with one side of the anti-slip block 45. The other side of the anti-slip block 45 is in sliding contact with the bearing block 44. The bearing block 44 is connected to the inner frame block 42. The roof body 1 is pinned to the wall through the pin block 43, and the anti-slip block 45 and the bearing block 44 further prevent the pin block 43 from falling off, making the installation and disassembly process of the roof body 1 simple and convenient without the need for complicated tools or techniques, and ensuring the stability and reliability of the connection between the roof body 1 and the wall. This connection method can significantly shorten the construction period, reduce the time and resource consumption of on-site disassembly and assembly, and facilitate reuse after subsequent disassembly, further meeting the requirements of green buildings for resource recycling.

[0020] The recovery device 25 includes a first rotating block 251, one end of the first rotating block 251 is rotatably connected to one end of the second rotating block 253, the rotation angle of the first rotating block 251 and the second rotating block 253 is 30 degrees, the angle surface between the first rotating block 251 and the second rotating block 253 is connected to the two ends of the reset elastic member 252, the other end of the second rotating block 253 is in contact with one end of the clamping block 255, the other end of the clamping block 255 is connected to the recovery wheel 254, the recovery wheel 254 is connected to the end of the rotating shaft 26, the outer ring of the recovery wheel 254 is connected to the recovery rope 256, the outer ring of the recovery wheel 254 is provided with a protective shell, and the protective shell is connected to the guide rail structure 21, one of the first rotating blocks 251 is connected to the trigger device 24 at the other end, the trigger device 24 includes an electric push rod 241, the electric push rod 241 is symmetrically provided with a guide probe 242 on the top, one of the probes 242 is electrically connected to the travel switch, and the other probe 242 is electrically connected to the electric push rod 241 When a very small amount of rainwater causes the two probes 242 to form a closed circuit, the travel switch is triggered to open the electric push rod 241 once, so that the electric push rod 241 drives the first rotating block 251, the second rotating block 253 and the reset elastic member 252 to move upward, and then the counterweight block 27 and the counterweight rope 271 allow the slider to be affected by gravity along the guide rail to cover the roof body 1 with the protective film 22, and then the electric push rod 241 is reset. When the rain stops, the protective film 22 is reversed and recovered by manually pulling the recovery rope 256, and then it will not rotate under the action of the first rotating block 251, the second rotating block 253 and the reset elastic member 252, so that the protective film 22 is recovered for limiting. At the same time, it should be stated that the travel switch adopts a single trigger mechanism, and only supports one start-up travel operation after power-on. If the travel needs to be started again, the power must be turned off and on again, and the secondary start will not be triggered during the power-on process.

[0021] A funnel-shaped collecting hood 243 is arranged on the outer circle of the two probes 242. The collecting hood 243 has a drainage port 2431.

The funnel-shaped collecting hood 243 efficiently collects rainwater from a larger range by expanding the surface area. The funnel-shaped collecting hood 243 efficiently collects rainwater from a larger range by expanding the surface area, thereby making it easier for the probe 242 to generate a closed loop, thereby realizing automatic control of the opening of the protective film 22.

[0022] The drainage and cleaning structure 3 includes a drainage channel 31, which is connected to the roof body 1 through a plurality of equally spaced connecting rods 311. The inner wall of the drainage channel 31 is in contact with a cleaning scraper 32. Both ends of the cleaning scraper 32 are transmission-connected to symmetrically arranged water wheels 33. Since the drainage channel 31 drains water to both sides of the roof body 1, it may cause fallen leaves that enter the drainage channel 31 to be unable to be discharged due to the low flow rate of rainwater. Long-term accumulation may cause drainage blockage and lose the drainage effect on both sides. Through the drainage and cleaning structure 3, when rainwater flows into the water wheel 33, it will drive the cleaning scraper 32 to rotate and push the collected fallen leaves to the drainage channel 31, thereby realizing automatic cleaning and discharge of fallen leaves.

[0023] The water wheel 33 is rotatably connected to the water guide cover 35, and the water guide cover 35 is connected to the roof body 1. The water flow direction is optimized by the water guide cover 35, and the water flow is concentrated and accurately impacts the water wheel 33, so as to more efficiently convert the kinetic energy of the water into mechanical energy, drive the water wheel 33 to rotate, and achieve a stable transmission effect.

[0024] The other end of the protective film 22 is connected to a triangular guide scraper 34, and the guide scraper 34 is connected to a slider. Through the triangular guide scraper 34, the flowing rainwater can be more efficiently guided to accurately impact the water wheel 33, thereby improving the conversion efficiency of the kinetic energy of the rainwater.
