Description

Technical Field

[0001] This invention relates to the field of green building technology, and more specifically, to a green building energy-saving roof structure. Background Technology

[0002] Green building refers to high-quality buildings that conserve resources, protect the environment, reduce pollution, and provide people with healthy, suitable, and efficient living spaces throughout their entire life cycle, maximizing the harmonious coexistence between humans and nature. Green building emphasizes the indoor environment because the mainstream idea in the air conditioning industry is to strive for a balance between the internal and external environments. Different needs are expressed for the internal environment, namely health, comfort, and the productivity of building users. The quality of air reflects the degree to which people's environmental requirements are met.

[0003] The roof is the surface of a building and serves as a protective structure that separates the house from the outside world, protecting it from sun, rain, wind, and snow. However, traditional roof structures cannot prevent direct sunlight from hitting the walls during hot and dry summers, which can lead to the interior being baked and the indoor temperature becoming extremely high. Therefore, this invention proposes a green building energy-saving roof structure to solve the above problems. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a green building energy-saving roof structure. By setting a planting box for planting plants on one side of a double-layered partition board, the direct sunlight on the double-layered partition board is reduced, thereby lowering the indoor temperature. At the same time, combined with the loss of soil moisture in the planting box, the plants are automatically watered while carrying away heat from the air, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a green building energy-saving roof structure, including a roof panel mechanism, wherein a water storage mechanism and a greening mechanism are fixedly installed on one side of the roof panel mechanism, and a filtration mechanism is provided inside the water storage mechanism;

[0006] The roof panel mechanism includes a double-layer partition panel, and a reinforced frame is fixedly installed on the outer wall of the double-layer partition panel. A ventilation opening is provided at the horizontal centerline position of the double-layer partition panel.

[0007] The greening mechanism includes a planting box located at the bottom of the water storage tank. A second sealing piston gasket is fixedly installed on one side of the planting box, and the second sealing piston gasket is located on the side of the vent. The greening mechanism also includes a slide rail fixedly installed on one side of the reinforced frame. A slider is slidably installed inside the slide rail. A balancing rope is fixedly connected to the top of the slider. The end of the balancing rope away from the slider is fixedly connected to the planting box. The filtration mechanism includes drive wheels rotatably installed on both sides of the water storage tank. The balancing rope engages with the outer wall of the drive wheel. A limit block is fixedly installed on the outer wall of the balancing rope. A return spring is fixedly installed between the limit block and the slide rail.

[0008] In a preferred embodiment, the water storage mechanism includes a water storage tank fixedly installed on one side of a double-layer isolation plate, and the bottom of the water storage tank is provided with a leakage hole;

[0009] A perforated plate is fixedly installed at the bottom of the hole, and a first sealing piston gasket is inserted into the inner cavity of the hole. The first sealing piston gasket is located at the top of the perforated plate.

[0010] In a preferred embodiment, two connecting plates are fixedly installed on the top of the first sealing piston gasket, and a supporting slide rod is fixedly installed on the bottom of the two connecting plates. The supporting slide rod moves up and down at the bottom of the water storage tank, and a telescopic spring is fixedly installed at the bottom of the water storage tank. The end of the telescopic spring away from the water storage tank is fixedly connected to the bottom of the supporting slide rod.

[0011] In a preferred embodiment, a first magnetic block is fixedly installed on the top of the limiting block, and a second magnetic block is fixedly installed on one side of the slide rail;

[0012] A limiting block is fixedly installed on one side of the reinforced frame, and a wear-resistant pressure pad is fixedly installed on the top of the planting box.

[0013] In a preferred embodiment, the drive wheel penetrates the inner wall of the water storage tank, and a rotating cylinder connected to the drive wheel is rotatably installed inside the water storage tank. Multiple arc-shaped scrapers are fixedly installed on the outer wall of the rotating cylinder in a ring-shaped manner at equal intervals.

[0014] In a preferred embodiment, the guide channel is arranged in a straight strip shape, the cross section of the guide channel is inclined relative to the rotating cylinder, and the guide direction of the inclined rotating cylinder is towards the outer edge of the arc-shaped scraper.

[0015] And / or a sealing strip is attached to the edge of the guide channel, and the two ends of the sealing strip are connected to the two sides of the guide channel by TPE rubber strips. Under normal conditions, the sealing strip and the guide channel are connected in a sealed manner. When the drum rotates, the sealing strip and the guide channel are separated.

[0016] In a preferred embodiment, the rotating drum is hollow, and the outer wall of the rotating drum is provided with multiple guide grooves, and the multiple arc-shaped scrapers are provided with a number of water filtering holes.

[0017] In a preferred embodiment, limiting blocks are fixedly installed on the adjacent sides of the reinforced plate frame, and limiting slots are opened on the sides of the reinforced plate frame away from the limiting blocks. The limiting blocks are made of water-swellable rubber.

[0018] In a preferred embodiment, a mesh sleeve is fitted around the outer periphery of the limiting insert, the mesh sleeve being made of PVC material.

[0019] The technical effects and advantages of this invention are as follows:

[0020] 1. This invention reduces direct sunlight on the double-layered partition board by setting up a planting box for planting plants on one side of the partition board, thereby lowering the indoor temperature. At the same time, a water storage tank is set on the top of the planting box to collect and store rainwater. In dry weather, the rainwater in the storage tank can continuously irrigate the plants in the planting box. The water carries away the hot air around the double-layered partition board and irrigates the plants, thereby promoting plant growth, purifying the air, beautifying the environment, and achieving a green and energy-saving effect.

[0021] 2. This invention, by adjusting the increase and loss of soil moisture in the planting box, causes the planting box to move the second sealing piston pad up or down to one side of the double-layer isolation plate, so that the ventilation opening is in a cycle of opening and closing, allowing air to circulate and allowing outside air to enter the room through the ventilation opening, thereby circulating the indoor air and thus helping to save energy.

[0022] 3. This invention, by moving the balance rope back and forth, can drive the transmission wheel to rotate, which in turn causes the rotating drum to drive the arc-shaped scraper to rotate, scraping away impurities deposited at the bottom of the water storage tank. The rotating arc-shaped scraper collects water impurities into the inner cavity of the rotating drum, thus preventing impurities from clogging the perforated plate as they fall with the water flow. It also ensures that the water storage tank on one side of each double-layer isolation plate can store water, thereby preventing interference with the watering of plants and thus affecting their growth.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Refer to the instruction manual appendix Figure 1-7 An embodiment of the present invention provides a green building energy-saving roof structure, such as... Figure 1As shown, the system includes a roof panel mechanism 1. A water storage mechanism 2 and a green plant mechanism 3 are fixedly installed on one side of the roof panel mechanism 1. The green plant mechanism 3 is used to plant green plants on one side of the roof panel mechanism 1, which can beautify the environment and purify the air, thus playing a green and environmentally friendly role. At the same time, in conjunction with the water storage mechanism 2, rainwater is collected and used to water the green plant mechanism 3 to prevent the plants from drying out. The green plant mechanism 3 is preferably planted with vines, so that the vines grow and hang on one side of the green plant mechanism 3, which can provide shade on one side of the roof panel mechanism 1, thereby reducing the heat received by the roof panel mechanism 1 from the sun and thus playing an auxiliary cooling role. The water storage mechanism 2 is equipped with a filter mechanism 4 inside. The filter mechanism 4 is used to assist the green plant mechanism 3 in moving up and down, enhance the stability of the movement of the green plant mechanism 3, and filter impurities in the water stored inside the water storage mechanism 2 during the up and down movement, so as to prevent rainwater mixed with too much dust from clogging the outlet of the water storage mechanism 2 and thus affecting the watering of the plants.

[0033] Combination Figure 3-4 As shown, the roof structure 1 includes a double-layer partition plate 101, a reinforced frame 102 fixedly installed on the outer wall of the double-layer partition plate 101, and a ventilation opening 103 at the horizontal centerline of the double-layer partition plate 101. The water storage structure 2 includes a water storage tank 21 fixedly installed on one side of the double-layer partition plate 101. The water storage tank 21 is used to collect and store rainwater. Figure 7As shown, a drain hole 22 is provided at the bottom of the water storage tank 21. A perforated plate 23 is fixedly installed at the bottom of the drain hole 22. A first sealing piston gasket 24 is inserted into the inner cavity of the drain hole 22. The first sealing piston gasket 24 is located on top of the perforated plate 23. When the first sealing piston gasket 24 is inserted into the inner cavity of the drain hole 22, it can prevent water stored in the inner cavity of the water storage tank 21 from flowing out. When the first sealing piston gasket 24 blocks the inner cavity of the drain hole 22, the water stored in the water storage tank 21 can flow out through the perforated plate 23. At the same time, the perforated plate 23 is set to slow down the falling speed of the water stored in the inner cavity of the water storage tank 21, so that the water flowing down through the perforated plate 23 is uniform and slow, thereby avoiding the situation where too much water is added at one time and the plants inside the greening mechanism 3 are drowned. Two connecting support plates 25 are fixedly installed on the top of the first sealing piston gasket 24, and a supporting slide rod 2 is fixedly installed on the bottom of the two connecting support plates 25. 6. The supporting slide rod 26 moves up and down at the bottom of the water storage tank 21, and a telescopic spring 27 is fixedly installed at the bottom of the water storage tank 21. The end of the telescopic spring 27 away from the water storage tank 21 is fixedly connected to the bottom of the supporting slide rod 26. Under normal conditions, the telescopic spring 27 covers the outer wall of the supporting slide rod 26 and is in an expanded state, so that the supporting slide rod 26 extends downward out of the bottom of the water storage tank 21 and pulls the first sealing piston pad 24 into the inner cavity of the leakage hole 22 and fits against the hollow plate 23, so that the water stored in the inner cavity of the water storage tank 21 will not flow out. When the supporting slide rod 26 is pushed upward, it will push the first sealing piston pad 24 to move upward as a whole, and then move out of the inner cavity of the leakage hole 22, so that a gap is created between the water storage tank 21 and the first sealing piston pad 24, and then the water stored in the inner cavity of the water storage tank 21 flows out through the gap and the hollow plate 23.

[0034] Reference Figure 5As shown, the greening mechanism 3 includes a planting box 34 located at the bottom of the water storage tank 21. Vines are planted inside the planting box 34. As the vines grow, their branches and leaves hang down to one side of the planting box 34, effectively blocking sunlight from the outer wall of the double-layer partition 101. Especially in summer, this reduces sunlight exposure to the double-layer partition 101, thereby lowering its temperature and preventing it from becoming too hot and affecting the indoor temperature. Simultaneously, the plant growth process continuously purifies the air. A second sealing piston gasket 35 is fixedly installed on one side of the planting box 34. The second sealing piston gasket 35 is located on one side of the vent 103. When the second sealing piston gasket 35 moves to the vent 103, it can block the vent 103, thereby preventing rainwater from entering the interior of the vent 103 and entering the room. The greening mechanism 3 also includes a slide rail 31 fixedly installed on one side of the reinforced frame 102. A slider 32 is slidably installed inside the slide rail 31. A balance rope 33 is fixedly connected to the top of the slider 32. The end of the balancing rope 33 away from the slider 32 is fixedly connected to the planting box 34. The filtration mechanism 4 includes a transmission wheel 41 rotatably installed on both sides of the water storage tank 21. The balancing rope 33 engages with the outer wall of the transmission wheel 41. When the planting box 34 pulls the balancing rope 33 downward, the end of the balancing rope 33 with the slider 32 slides upward inside the slide rail 31. When the planting box 34 moves upward, the slider 32 moves downward inside the slide rail 31. A limit block 36 is fixedly installed on the outer wall of the balancing rope 33, and the limit block 36 is fixedly connected to the slide rail 31. A return spring 37 is fixedly installed. Under normal conditions, the return spring 37 is in an expanded state, pushing the end of the balance rope 33 connected to the slider 32 to remain at the horizontal centerline position of the slide rail 31. When the end of the balance rope 33 connected to the planting box 34 moves down, it can pull the end of the balance rope 33 connected to the slider 32 to move up, thereby causing the return spring 37 to gradually contract. When the weight of the planting box 34 is reduced, combined with the elastic restoring force of the return spring 37, it will push the end of the balance rope 33 connected to the slider 32 to move down again to return to its original position.

[0035] Furthermore, in combination Figure 4As shown, a first magnetic block 38 is fixedly installed on the top of the limiting block 36, and a second magnetic block 39 is fixedly installed on one side of the slide rail 31. When the limiting block 36 moves upward as a whole until the first magnetic block 38 and the second magnetic block 39 are in contact with each other, the first magnetic block 38 and the second magnetic block 39 attract and fix each other together. On the one hand, this limits the downward movement of the planting box 34, and on the other hand, it allows the planting box 34 to drive the second sealing piston gasket 35 to seal one side of the vent 103, thereby preventing rainwater from entering the room through the vent 103. At the same time, a limiting support block 310 is fixedly installed on one side of the reinforced frame 102. The limiting support block 310 is set to limit the downward movement range of the slider 32. In order to prevent the top of the planting box 34 from being damaged by long-term pressure against the support slide rod 26, a wear-resistant pressure pad 311 is fixedly installed on the top of the planting box 34.

[0036] In practice, during rainy weather, the water storage tank 21 normally collects rainwater, which washes over the planting box 34, causing the soil inside to absorb water and increase in weight. This increased weight causes the balance rope 33 connected to the planting box 34 to move downwards, while the end of the balance rope 33 connected to the slider 32 moves upwards. Simultaneously, the planting box 34 moves the second sealing piston gasket 35 to seal one side of the vent 103. When the weather is dry and sunny, as the temperature rises, the soil inside the planting box 34 loses moisture, and the overall weight of the planting box 34 gradually decreases. This, combined with the elastic restoring force of the return spring 37, pushes the slider 32 downwards, causing the planting box 34 to gradually rise. As the planting box 34 rises, it gradually comes into contact with the supporting slide bar 26, which in turn pushes the supporting slide bar 26 upward, causing the first sealing piston pad 24 to move upward and expose the gap between the water storage tank 21 and the first sealing piston pad 24. This allows the water stored in the inner cavity of the water storage tank 21 to slowly flow out through the gap from the perforated plate 23 and drip onto the planting box 34, slowly replenishing the water in the planting box 34. At the same time, the second sealing piston pad 35 loses its blockage of the vent 103, allowing air to circulate through the vent 103. This allows outside air to enter the room through the vent 103, thus circulating the air in the room. When enough water is replenished, the soil absorbs water and becomes heavier, which in turn pulls the planting box 34 downward again.

[0037] Furthermore, when multiple roof panel structures 1 are installed together, since the greening structure 3 on one side of the upper roof panel structure 1 is on top of the lower roof panel structure 1, during the long-term watering process of the greening structure 3 of the upper roof panel structure 1, water carrying soil is easily allowed to fall. To avoid affecting the cleanliness of the water inside the rainwater collection tank 21 on the lower roof panel structure 1, refer to... Figure 4As shown, the drive wheel 41 penetrates the inner wall of the water storage tank 21, and a rotating drum 42 connected to the drive wheel 41 is rotatably installed inside the water storage tank 21. Multiple arc-shaped scrapers 43 are fixedly installed in a ring-shaped arrangement on the outer wall of the rotating drum 42 at equal intervals. When the balance rope 33 moves back and forth, it drives the drive wheel 41 to rotate, which in turn causes the rotating drum 42 to drive the arc-shaped scrapers 43 to rotate, scraping away impurities deposited at the bottom of the water storage tank 21 and preventing impurities from falling with the water flow. The hollow plate 23 is blocked in the middle. At the same time, the rotating drum 42 is hollow. The outer wall of the rotating drum 42 is provided with multiple guide grooves 44, and multiple arc-shaped scrapers 43 are provided with several water filtering holes. When the rotating drum 42 drives the arc-shaped scrapers 43 to rotate in the water, it can roll up the impurities in the water. Then, combined with the contact between the arc-shaped scrapers 43 and the water, the impurities are blocked at the arc-shaped scrapers 43 and rolled into the inner cavity of the rotating drum 42 with the arc-shaped scrapers 43, thus collecting the impurities in the water.

[0038] Furthermore, to enhance the ease of installation between multiple double-layer isolation panels 101, refer to Figure 6-7 As shown, limiting blocks 104 are fixedly installed on the adjacent sides of the reinforced plate frame 102. Limiting slots 105 are opened on the sides of the reinforced plate frame 102 away from the limiting blocks 104. In use, the limiting block 104 on one side of one double-layer isolation plate 101 can be slidably inserted into the cavity of the limiting slot 105 on the other side of the double-layer isolation plate 101, thereby enabling the two double-layer isolation plates 101 to be quickly connected. Finally, the two reinforced plate frames 102 are connected together. The system can be re-secured by tightening bolts. Meanwhile, to prevent rainwater from seeping into the room from the connection between the two reinforced frame plates 102, the limiting plug 104 is made of water-swellable rubber. When in use, the limiting plug 104 expands due to the contact between rainwater and the limiting slot 105, thus sealing the gap between the two reinforced frame plates 102 and preventing rainwater from seeping in.

[0039] In another further embodiment, the guide channel is arranged in a straight strip shape, the cross-section of the guide channel is inclined relative to the rotating drum, and the guide direction of the rotating drum is inclined toward the outer edge of the arc-shaped scraper.

[0040] And / or a sealing strip is attached to the edge of the guide channel. The two ends of the sealing strip are connected to the two sides of the guide channel by TPE rubber strips. Under normal conditions, the sealing strip and the guide channel are connected in a sealed manner. When the drum rotates, the sealing strip and the guide channel are separated. The purpose of this setting is that when it rotates, it can form a normal passage through the centrifugal force, and under normal conditions, it forms a blocked state.

[0041] In addition, a mesh sleeve is fitted around the outer periphery of the limiting plug. The mesh sleeve is made of PVC material. Its purpose is to expand the water-swellable block after it comes into contact with water, and to use the mesh sleeve for support to improve the firmness of the seal.

[0042] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change.

Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this invention can be combined with each other.

[0044] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
