Description

Technical Field

[0001] This invention relates to the field of building structure technology for greening rooftops, specifically to a building structure for greening rooftops. Background Technology

[0002] With increasing urban building density, land resources available for ground-level greening are becoming increasingly scarce. Rooftop greening, as an effective form of vertical greening, is gradually gaining widespread attention. Rooftop greening not only beautifies the urban landscape and mitigates the urban heat island effect, but also provides insulation, reduces building energy consumption, and purifies the air, making it an important pathway to achieving green building and sustainable urban development.

[0003] Currently, common rooftop greening methods include laying planting soil on the roof and planting drought-resistant plants, or using modular planting containers. However, the above greening structures have obvious shortcomings in actual use: when the summer sun is too strong, the rooftop plants are exposed to strong direct sunlight for a long time, which can easily lead to leaf burn, excessive water evaporation, and excessively high root temperature, resulting in poor plant growth or even withering and death.

[0014] This invention provides a building structure for greening the rooftop of buildings. It has the following beneficial effects: 1. This invention, through the coordination of a gas storage box, piston plate, spring plate, limiting rod, copper plate, baffle, return spring, and support frame, allows the copper plate to receive a large amount of heat when the sun is too strong in summer. This heats the carbon dioxide in the gas storage box, causing the heated carbon dioxide gas to expand. This allows the limiting rod to move out of the baffle, releasing the baffle's restriction. The baffle then blocks the top of the plant pot, effectively shielding the plant from sunlight and solving the problem of prolonged direct sunlight damaging the plant surface.

[0015] 2. This invention, by incorporating a photosensitive sensor, an electric telescopic rod, a pressing block, and a control panel, allows the photosensitive sensor to detect a signal at night when it is dark. This signal is transmitted to the control panel, which then activates the electric telescopic rod, causing it to move the pressing block. The pressing block then presses the baffle back to its original position, preventing it from obstructing the plant pot. Furthermore, at night, the copper plate is no longer exposed to sunlight, causing its temperature to drop and preventing the expansion of carbon dioxide gas. This allows the limiting rod to insert into the baffle, limiting its position and enabling normal photosynthesis during the day. This automatic reset mechanism ensures normal photosynthesis.

[0016] 3. This invention, by setting up a water storage tank, a water collection tank, a drip pipe, a bending block, a transmission plate, a transmission spring, a fixing block, a hinge block, an inclined block, and a sealing plate, allows the bending block to move while the baffle blocks cover the plant pot. This movement compresses the inclined surface of the inclined block, causing it to move the sealing plate downwards. This opens the channel between the water storage tank and the water collection tank, allowing water from the storage tank to flow into the collection tank. The drip pipe then adds water to the plant pot, solving the problem of excessive sunlight causing the soil moisture in the plant pot to evaporate too quickly, affecting the normal growth of the plant and reducing its lifespan.

[0017] 4. When the bending block moves away from the inclined block, the sealing plate re-seals the connection between the water storage tank and the water collection tank. When the baffle is reset, it can drive the bending block to reset, causing the bending block to squeeze the inclined block and rotate, thus preventing the inclined block from moving downwards. This prevents the sealing plate from opening when the baffle is reset, thus preventing water from being added to the water collection tank. This solves the problem of excessive water being added to the plant pot, which can damage the plants.

[0018] 5. By setting up squeezing columns, triangular blocks, compaction plates, and elastic sheets, this invention enables the squeezing columns to press against the inclined surfaces of the triangular blocks when the baffle is used to shield the plant pots. This allows the compaction plates to compact the soil inside the plant pots, solving the problem of soil softening caused by sun exposure, which prevents the plant roots from making close contact with the soil and reduces the lifespan of the plants.

[0019] 6. This invention, by setting up a push rod, an air-filling box, a push plate, an air-filling pipe, and an air-inlet pipe, allows the air-filling pipe to add gas into the soil when the compaction plate moves, quickly reducing the internal temperature of the plant pot and preventing root burn from high temperature. This solves the problem of plant root damage caused by high soil temperature inside the plant pot after exposure to the sun. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1-7One embodiment of the present invention is: a building structure for greening the roof of a building, comprising: a slope plate 1, a support plate 2, a planter 3, a support base 4, an air storage box 5, a piston plate 6, a spring plate 7, a limiting rod 8, a copper plate 9, a baffle 10, a return spring 11, a support frame 12, a photosensitive sensor 13, an electric telescopic rod 14, a compression block 15, and a control panel 16; the top of the slope plate 1 is fixed to the support base 4, the support plate 2 is fixed to the side wall of the support base 4, the planter 3 is detachably installed on the top of the support plate 2, the air storage box 5 is fixed to the top of the support base 4, the piston plate 6 is slidably installed on the inner side of the air storage box 5, the bottom of the piston plate 6 is fixed to the bottom of the piston plate 6, the bottom of the spring plate 7 is fixed to the inner side of the air storage box 5, the cavity formed by the air storage box 5 and the bottom of the piston plate 6 is filled with carbon dioxide gas, and the baffle 10 is slidably installed on the support base 4. At the top, a return spring 11 is fixed to the side wall of the baffle 10. The end of the return spring 11 is fixed to the side wall of the support base 4. The baffle 10 is used to shield and protect the green plants in the plant pot 3. The copper plate 9 passes through the side wall of the gas storage box 5 and is fixedly connected at the through point. A limit rod 8 is fixed to the top of the piston plate 6. The end of the limit rod 8 is attached to the inner side of the top of the baffle 10. The limit rod 8 is used to limit the baffle 10. A support frame 12 is fixed to the top of the gas storage box 5. A photosensitive sensor 13 is fixed to the top of the support frame 12. A control panel 16 is fixed to the side wall of the support base 4. The control panel 16 is electrically connected to the photosensitive sensor 13. An electric telescopic rod 14 is fixed to the inner side of the bottom of the support frame 12. The electric telescopic rod 14 is electrically connected to the control panel 16. A pressing block 15 is fixed to the output end of the electric telescopic rod 14.

[0024] By setting up the gas storage box 5, piston plate 6, spring plate 7, limit rod 8, copper plate 9, baffle 10, return spring 11 and support frame 12, when the outside sun is too strong in summer, the copper plate 9 will receive a lot of heat, which will heat the carbon dioxide in the gas storage box 5. The heated carbon dioxide gas will expand, which will allow the limit rod 8 to move out of the baffle 10, releasing the limit on the baffle 10. This will allow the baffle 10 to block the top of the green plant pot 3, thus blocking the green plant from sunlight and solving the problem that the green plant is easily damaged by the sun shining directly on its surface for a long time. By setting up a photosensitive sensor 13, an electric telescopic rod 14, a squeezing block 15, and a control panel 16, when it gets dark at night, the photosensitive sensor 13 senses a signal and transmits an electrical signal to the control panel 16. The control panel 16 can then control the electric telescopic rod 14 to move the squeezing block 15. The squeezing block 15 can then squeeze the baffle 10 to reset, preventing the baffle 10 from blocking the plant pot 3. At night, because the copper plate 9 is no longer exposed to sunlight, its temperature decreases, preventing the carbon dioxide gas from expanding. This allows the limiting rod 8 to insert into the baffle 10 and limit its movement, ensuring normal photosynthesis during the day. This achieves an automatic reset effect, allowing normal photosynthesis to proceed.

[0025] In this embodiment, the plant is planted in the planter 3. When the sunlight intensity is too high in summer, the copper plate 9 absorbs a lot of heat and heats up. When the temperature of the copper plate 9 is too high, it transfers the heat to the gas storage box 5, causing the carbon dioxide gas in the gas storage box 5 to expand. The carbon dioxide expands and squeezes the piston plate 6, causing the piston plate 6 to move upward. This stretches and deforms the elastic sheet 184. When the piston plate 6 moves upward, it can drive the bending block 174 to move out of the baffle 10, thus contacting the limit of the baffle 10. Because the return spring 11 is in a compressed state, it can drive the baffle 10 to move, allowing the baffle 10 to move to the top of the planter 3, blocking the top of the planter 3 and protecting the plant from prolonged exposure to excessive sunlight, which could damage the plant. When there is no light at night, the photosensitive sensor 13 will detect a signal and transmit an electrical signal to the control panel 16. The control panel 16 can then control the electric telescopic rod 14 to start, causing the electric telescopic rod 14 to move the pressing block 15. The pressing block 15 can then press the baffle 10 to reset, compressing the reset spring 11. When the baffle 10 resets, the hole on the baffle 10 will align with the limiting rod 8. Because there is no light at night to expose the copper plate 9, the temperature of the copper plate 9 will decrease. Due to the principle of thermal expansion and contraction, the carbon dioxide gas in the gas storage tank 5 will no longer press the piston plate 6. Since the spring plate 7 is in a stretched and deformed state, the piston plate 6 will move the limiting rod 8 downward, allowing the limiting rod 8 to extend into the baffle 10 and limit the baffle 10. When it is daytime, the photosensitive sensor 13 will send a signal again, transmitting an electrical signal to the control panel 16, which will then control the electric telescopic rod 14 to start again and reset the electric telescopic rod 14.

[0026] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, a water-adding device is provided on the support base 4, which is used to add water to the green plant pot 3, and a compaction device is provided on the green plant pot 3, which is used to prevent the soil in the green plant pot 3 from becoming loose. The water filling device includes: a water storage tank 171, a water collection tank 172, a drip pipe 173, a bending block 174, a transmission plate 175, a transmission spring 176, a fixing block 177, a hinge block 178, an inclined block 179, and a sealing plate 1710; the water storage tank 171 is located on a support base 4, and the support base 4 has mesh openings for adding water into the water storage tank 171; the support base 4 has a water collection tank 172; and the side wall of the support base 4... A drip pipe 173 is fixedly installed and communicates with the water collection tank 172. The drip pipe 173 is used to add water to the plant pot 3. A bending block 174 passes through the side wall of the support base 4 and is slidably connected at the penetration point. A transmission plate 175 is fixed to the end of the bending block 174. A transmission spring 176 is fixed to the side wall of the transmission plate 175. The side of the transmission spring 176 away from the transmission plate 175 is fixed to the side wall of the support base 4. Fixed block 177 is fixed to the bottom of baffle 10. Fixed block 177 is used to press transmission plate 175 to reset. Hinged block 178 is slidably installed on the inner side of support base 4. Return spring is fixed to the bottom of hinge block 178. The bottom of return spring is fixed to the inner side of support base 4. Inclined block 179 is rotatably installed on the inner side of hinge block 178. Torsion spring is fixed to the side wall of inclined block 179. The side of torsion spring away from inclined block 179 is fixed to the inner side of hinge block 178. Bending stop is fixed to the side wall of hinge block 178. The side wall of bending stop fits with inclined block 179. Bending stop is used to limit the rotation of inclined block 179. Connecting block is fixed to the side wall of hinge block 178. Sealing plate 1710 is fixed to the end of connecting block. Sealing plate 1710 is slidably installed on the inner side of support base 4. Sealing plate 1710 is used to seal between water storage tank 171 and water collection tank 172.

[0027] By setting up a water storage tank 171, a water collection tank 172, a drip pipe 173, a bending block 174, a transmission plate 175, a transmission spring 176, a fixing block 177, a hinge block 178, an inclined block 179, and a sealing plate 1710, when the baffle 10 blocks the green plant pot 3, it can move the bending block 174 to squeeze the inclined surface of the inclined block 179, causing the inclined block 179 to drive the sealing plate 1710 to move downward, opening the channel between the water storage tank 171 and the water collection tank 172, allowing water in the water storage tank 171 to flow into the water collection tank 172. Through the drip pipe 173, water can be added to the green plant pot 3, solving the problem that excessive sunlight causes the soil moisture in the green plant pot 3 to evaporate too quickly, affecting the normal growth of the green plants and reducing their lifespan. When the bending block 174 is removed from the inclined block 179, the sealing plate 1710 seals the connection between the water storage tank 171 and the water collection tank 172 again. When the baffle 10 is reset, it can drive the bending block 174 to reset, causing the bending block 174 to squeeze the inclined block 179 and rotate, so that the inclined block 179 will not move downward. This prevents the sealing plate 1710 from opening when the baffle 10 is reset, and prevents water from being added to the water collection tank 172. This solves the problem of excessive water added to the plant pot 3, which causes damage to the plants.

[0028] The compaction device includes: a squeezing column 181, a triangular block 182, a compaction plate 183, an elastic sheet 184, a push rod 185, an air filling box 186, a push plate 187, an air filling pipe 188, and an air inlet pipe 189; the squeezing column 181 is fixed to the bottom of the fixing block 177, the triangular block 182 is slidably installed on the top of the planter 3, and the end of the triangular block 182 is fixed with the compaction plate 183, which is used to squeeze the soil in the planter 3; one side of the elastic sheet 184 is fixed to the side wall of the compaction plate 183, and the other side of the elastic sheet 184 is fixed to the top protrusion of the planter 3; the side wall of the compaction plate 183 is fixed with the push rod 185. An air filling box 186 is fixed to the outer wall of the pot 3. A push plate 187 is slidably installed on the inner side of the air filling box 186. The end of the push rod 185 is fixed to the side wall of the push plate 187, and the push rod 185 passes through the side wall of the air filling box 186 and is slidably connected at the penetration point. An air filling pipe 188 is fixed to the side wall of the air filling box 186 and is connected to the inside of the green plant pot 3. An air inlet pipe 189 is fixed to the outer wall of the air filling box 186. One-way valves are fixed to the outer walls of the air inlet pipe 189 and the air filling pipe 188. The one-way valve on the outer wall of the air filling pipe 188 can only allow air to exit and not allow air to enter. The one-way valve on the outer wall of the air inlet pipe 189 can only allow air to enter and not allow air to exit.

[0029] By setting up the squeezing column 181, the triangular block 182, the compaction plate 183 and the elastic sheet 184, when the baffle 10 blocks the green plant pot 3, the squeezing column 181 will squeeze the inclined surface of the triangular block 182, and the compaction plate 183 will compact the soil in the green plant pot 3. This solves the problem that the soil in the green plant pot 3 is exposed to the sun and becomes soft, which prevents the roots of the plants from making close contact with the soil and reduces the lifespan of the plants. By setting up push rod 185, air box 186, push plate 187, air pipe 188 and air inlet pipe 189, when the compaction plate 183 moves, the air pipe 188 can add gas into the soil, quickly reduce the internal temperature of the green plant pot 3, avoid root burn from high temperature, and solve the problem of damage to the green plant roots caused by high soil temperature inside the green plant pot 3 after exposure to the sun. In this embodiment, when the baffle 10 moves, it can drive the fixed block 177 to move, preventing the fixed block 177 from pressing the transmission plate 175. Because the transmission spring 176 is in a compressed state, it will drive the transmission plate 175 to move. When the transmission plate 175 moves, it can drive the bending block 174 to move. When the bottom protrusion of the bending block 174 moves to the inclined surface of the inclined block 179, it can press the inclined surface of the inclined block 179, causing the side wall of the inclined block 179 to press against the bending baffle, thus preventing the inclined block 179 from rotating. Furthermore, because the spring force coefficient of the transmission spring 176 is five times that of the return spring, the bottom of the bending block 174 will... The protruding part presses the inclined block 179 downward, causing the hinge block 178 to move downward, compressing the return spring. When the hinge block 178 moves downward, it can drive the connecting block downward, causing the sealing plate 1710 to move downward, opening the connection between the water storage tank 171 and the water collection tank 172, allowing water in the water storage tank 171 to enter the water collection tank 172. When the bottom of the bending block 174 moves away from the top of the inclined block 179, since the inclined block 179 is not pressed and the return spring is in a compressed state, the hinge block 178 can drive the inclined block 179 to return upward, causing the connecting block to drive the sealing plate 1710 to return upward, so that the sealing plate 1710 can seal the connection between the water storage tank 171 and the water collection tank 172 again. When the baffle 10 fixing block 177 is reset, the fixing block 177 will press the transmission plate 175, which will cause the transmission plate 175 to drive the bending block 174 to move. When the bottom protrusion of the bending block 174 moves to contact the plane of the inclined block 179, the bottom protrusion of the bending block 174 will press the inclined block 179, allowing the inclined block 179 to rotate, compressing the torsion spring, and preventing the inclined block 179 from driving the hinge block 178 to move downward, so that the sealing plate 1710 will not open.

[0030] When the baffle 10 blocks the greenery, the fixing block 177 moves the squeezing column 181. When the squeezing column 181 moves to the inclined surface of the triangular block 182, it squeezes the inclined surface of the triangular block 182, causing the triangular block 182 to be subjected to squeezing force and move into the green plant pot 3. This also causes the elastic sheet 184 to be compressed and deformed. As the triangular block 182 moves, the compaction plate 183 compacts the soil in the green plant pot 3. When the squeezing column 181 moves away from the triangular block 182, the triangular block 182 is no longer subjected to squeezing force, and the elastic sheet 184... It can drive the triangular block 182 and the compaction plate 183 to perform their functions; when the compaction plate 183 moves, it can drive the push rod 185 to move, so that the push rod 185 can squeeze the push plate 187, so that the push plate 187 can squeeze the gas in the gas filling box 186 and discharge it through the gas filling pipe 188, so that the gas can be added to the soil. When the compaction plate 183 drives the push rod 185 to reset, it can drive the push rod 185 to reset, so that the push plate 187 can draw the outside gas back into the gas filling box 186 through the air inlet pipe 189 for the next gas filling operation.
