Description

Technical Field

[0001] This application relates to the technical field of green building structures, and in particular to a building structure for greening the roof of a building. Background Technology

[0002] Rooftop greening can be understood as the general term for landscaping and planting trees and flowers on the roofs, terraces, balconies, or large artificial hills of buildings, structures, city walls, bridges, etc. Rooftop greening can increase the green space area of ​​cities, alleviate the scarcity of native plant communities caused by urban construction and hard paving, and mitigate the urban heat island effect caused by excessive deforestation and various forms of air pollution.

[0003] Currently, Chinese patent CN207040329U discloses a building structure for greening the roof of a building, including a mounting base. The right end of the mounting base is movably connected to a crankshaft via a mounting ear, and an adjusting screw is provided in the center of the crankshaft. The top end of the crankshaft is connected to a support plate via a mounting ear. The left and right ends of the support plate are respectively provided with baffles and locking devices, and a greening plate is provided between the baffles and the locking device. The right end of the greening plate is fixed by the locking device.

[0004] Regarding the aforementioned technologies, the inventors believe that in actual use, the greening panels connected to the support plate rely solely on external rainfall for irrigation, and rainwater typically floods the greening panels. During the rainy season with heavy rainfall, on the one hand, the vegetation on the greening panels is prone to root rot due to prolonged flooding by large amounts of rainwater; on the other hand, excess rainwater flows away along the inclined greening panels, resulting in a waste of rainwater resources. Summary of the Invention

[0005] In order to reduce the possibility of root rot in vegetation and to realize the recycling of rainwater resources, this application provides a building structure for greening the roof of a building.

[0006] This application provides a building structure for greening the rooftop of a building, which adopts the following technical solution:

[0007] A building structure for greening the rooftop of a building includes a placement trough, a water storage trough, a planting trough, and a shielding component. One placement trough is provided on each side of the water storage trough in the width direction. The length of the water storage trough is greater than the length of the placement trough. An overlapping ring is connected to the top edge of the planting trough. The planting trough is placed in the placement trough, and the overlapping ring overlaps the edge of the placement trough. Drainage holes are provided on the bottom surface of the planting trough. A gap is left between the bottom surface of the planting trough and the bottom surface of the placement trough. A connecting pipe is connected to the bottom surface of the water storage trough. The top of the water storage trough is lower than the top of the placement trough. The end of the connecting pipe away from the water storage trough is connected to the bottom surface of the placement trough. The water storage tank is connected by vertical rods at both ends along its length, and a horizontal rod connects the two vertical rods. The shielding assembly includes a rain shield, a floating ring, and a top rod. One rain shield is rotatably connected to each side of the horizontal rod along its width. The length of the rain shield is the same as the length of the placement trough. The floating ring is slidably disposed in the water storage tank, and the outer ring wall of the floating ring is in contact with the inner ring wall of the water storage tank. Two top rods are vertically connected to the floating ring, and the top ends of the two top rods correspond to and abut against the bottom surfaces of the two rain shields. When the floating ring rises to the top of the water storage tank, the rain shield, pushed by the top rods, shields the area above the planting trough.

[0008] By adopting the above technical solution, during rainfall, rainwater irrigates the planting trough and enters the storage tank through the opening at the top of the storage tank for storage. As the water level in the storage tank rises, the floating ring rises under the action of buoyancy, and the top rod lifts the rain shield rotatably connected to the horizontal rod. The rain shield blocks the planting trough, preventing rainwater from irrigating the vegetation in the planting trough. The water level in the storage tank is level with the water level in the placement trough. Rainwater in the placement trough enters the planting trough through the seepage holes. Through the cooperation of the placement trough, storage tank, planting trough, connecting components, and shielding components, moderate irrigation of the vegetation in the planting trough is achieved, reducing the possibility of root rot and realizing the recycling of rainwater resources.

[0009] Optionally, a first support rod is vertically fixed to the bottom surface of the transverse rod, and a second support rod is horizontally connected to the bottom end of the first support rod. A guide sleeve is connected to both ends of the second support rod, and the two guide sleeves correspond one-to-one with the two top rods. The top rods are slidably connected in the guide sleeves.

[0010] By adopting the above technical solution, when the push rod moves in the vertical direction, the push rod slides in the guide sleeve. The guide sleeve is designed to guide and limit the push rod, thereby improving the stability of the push rod during movement.

[0011] Optionally, the top end of the top rod is rotatably connected to an abutting roller, which abuts against the bottom surface of the rain shield.

[0012] By adopting the above technical solution, the setting of the abutting roller reduces the friction between the top of the top rod and the bottom surface of the rain shield, making it easier for the top rod to move on the bottom surface of the rain shield and reducing the possibility of friction damage to the rain shield.

[0013] Optionally, the water storage tank is provided with a squeezing assembly, which includes a first squeezing plate and a second squeezing plate. The first squeezing plate is slidably disposed in the water storage tank and is positioned above the floating ring. Both sides of the first squeezing plate in the width direction are provided with clearance grooves for the top rod to pass through. One end of the first squeezing plate abuts against the inner wall of one end of the water storage tank in the length direction. The second squeezing plate is slidably connected to the top surface of the first squeezing plate. The width of the first squeezing plate is equal to the width of the water storage tank. The top surface of the first squeezing plate is provided with a first driving member that drives the second squeezing plate to move along the length direction of the water storage tank. The vertical rod is provided with a second driving member that drives the first squeezing plate to move in the vertical direction.

[0014] By adopting the above technical solution, when the vegetation in the planting trough needs irrigation due to water shortage, the second squeezing plate moves under the drive of the first driving component to abut against the inner wall of one end of the water storage trough along its length. Simultaneously, the first and second squeezing plates seal the opening of the water storage trough. Driven downwards by the second driving component, the first and second squeezing plates force rainwater in the water storage trough into the placement trough through the connecting pipe. The rainwater then seeps into the planting trough through the infiltration holes to irrigate the vegetation, thus achieving full utilization of rainwater.

[0015] Optionally, the first driving component includes a drive motor and a drive screw. The drive screw is connected to the vertical rod, and one end of the drive screw is connected to the drive motor. The drive screw extends vertically downward and is threadedly connected to the first extrusion plate. The second driving component includes a drive cylinder, which is connected to the first extrusion plate. The output shaft of the drive cylinder extends along the length of the water storage tank and is connected to the second extrusion plate.

[0016] By adopting the above technical solution, when squeezing rainwater in the water storage tank, the drive cylinder is activated and drives the second squeezing plate to move. The second squeezing plate moves to abut against the inner wall of the water storage tank, and the first and second squeezing plates simultaneously seal the opening of the water storage tank. The drive motor drives the drive screw to rotate, and the first and second squeezing plates move vertically under the drive of the drive screw and the limitation of the inner wall of the water storage tank, realizing the automatic driving of the first and second squeezing plates.

[0017] Optionally, a solar panel is connected to the side of the rain shield away from the top rod, and the solar panel is electrically connected to the drive motor and the drive cylinder.

[0018] By adopting the above technical solution, the solar panel receives solar energy during the day and converts it into electrical energy to power the first and second drive components, thus achieving full utilization of resources.

[0019] Optionally, a first sealing strip is connected to the outer peripheral wall of the first extrusion plate, and a second sealing strip is connected to the outer peripheral wall of the second extrusion plate. Both the first sealing strip and the second sealing strip are fitted to the inner wall of the water storage tank.

[0020] By adopting the above technical solution, the setting of the first sealing strip and the second sealing strip reduces the gap between the edge of the first extrusion plate and the second extrusion plate and the inner wall of the water storage tank, which facilitates the extrusion of rainwater in the water storage tank by the first extrusion plate and the second extrusion plate.

[0021] Optionally, a filter plate is horizontally connected in the water storage tank, and the filter plate is located below the floating ring.

[0022] By adopting the above technical solution, the filter plate filters the rainwater collected in the water storage tank, reducing the impurity content entering the connecting pipe and reducing the possibility of impurities clogging the connecting pipe.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Through the cooperation of placement troughs, water storage troughs, planting troughs, connecting and shielding components, moderate irrigation of vegetation in the planting troughs is achieved, which can reduce the possibility of root rot in vegetation and realize the recycling of rainwater resources.

[0025] 2. The extrusion assembly squeezes rainwater from the storage tank into the placement tank through the connecting pipe, thus realizing the reuse of rainwater;

[0026] 3. The filter plate reduces the amount of impurities entering the connecting pipe, thus reducing the possibility of impurities clogging the connecting pipe. Attached Figure Description

The floating ring 62 is slidably disposed in the water storage tank 2, with its outer ring wall slidingly fitting against the inner circumferential wall of the water storage tank 2. Two top rods 63 are vertically fixed to the top of the floating ring 62, and each of the two top rods 63 corresponds to one of the two rain shields 61. An abutting roller 64 is rotatably connected to the top of each top rod 63, and the abutting roller 64 abuts against the bottom surface of the rain shield 61.

[0036] Reference Figure 2 The first support rod 65 is vertically fixed to the bottom end of the horizontal rod 13, and the second support rod 66 is horizontally fixed to the bottom end of the first support rod 65. The second support rod 66 is set perpendicular to the horizontal rod 13. One guide sleeve 67 is fixedly connected to each end of the second support rod 66, and the two guide sleeves 67 correspond one-to-one with the two top rods 63 and are slidably connected.

[0037] Reference Figure 3 and Figure 4 The extrusion assembly 7 includes a first extrusion plate 71, a second extrusion plate 72, a drive cylinder 73, a drive motor 74, a drive screw 75, and a mounting plate 76. The widths of the first extrusion plate 71 and the second extrusion plate 72 are equal to the width of the water storage tank 2, and the sum of the lengths of the first extrusion plate 71 and the second extrusion plate 72 is greater than the length of the water storage tank 2. The second extrusion plate 72 is slidably disposed on the top surface of the first extrusion plate 71, and the drive cylinder 73 is connected to the top surface of the first extrusion plate 71. The output shaft of the drive cylinder 73 extends along the length direction of the first extrusion plate 71 and is connected to one end of the second extrusion plate 72 along its length direction. The first extrusion plate 71 is slidably disposed in the water storage tank 2, and one end of the first extrusion plate 71 along its length direction is in contact with the inner wall of one end of the water storage tank 2 along its length direction. Both ends of the first extrusion plate 71 in the width direction are provided with relief grooves 77 for accommodating the push rod 63.

[0038] Reference Figure 3 The drive motor 74 is fixedly connected to the vertical rod 12, and one end of the drive screw 75 is connected to the output shaft of the drive motor 74. The drive screw 75 is vertically arranged and threadedly connected to the first extrusion rod. The mounting plate 76 is fixedly connected to the bottom end of the drive screw 75 to limit the first extrusion plate 71. Several solar panels 8 are connected to the side of the rain shield 61 away from the top rod 63. The solar panels 8 are electrically connected to the drive motor 74 and the drive cylinder 73 through the control system.

[0039] Referring to the figure, a first sealing strip 9 is fixedly connected to the outer peripheral wall of the first extrusion plate 71, and a second sealing strip 10 is fixedly connected to the outer peripheral wall of the second extrusion plate 72. Both the first sealing strip 9 and the second sealing strip 10 are fitted against the vertical inner wall of the water storage tank 2. A filter plate 11 is connected inside the water storage tank 2, and the filter plate 11 is located below the float plate.

[0040] Reference Figure 1-3 During rainfall, rainwater directly irrigates the vegetation in planting trough 4. Rainwater is collected in storage tank 2. As the water level rises, the floating ring 62 rises, causing the abutment roller 64 connected to the top of the top rod 63 to roll relative to the rain shield 61. The rain shield 61, pushed upwards by the top rod 63, flips over to cover the planting trough 4, reducing the risk of root rot caused by continuous rainwater inflow. The guide sleeve 67 guides and limits the vertical sliding of the top rod 63, improving its stability. The abutment roller 64 reduces friction between the top and the rain shield 61, minimizing the possibility of damage during rotation. Rainwater stored in storage tank 2 flows into placement trough 3 via connecting pipe 5. Rainwater in placement trough 3 seeps into planting trough 4 through seepage holes 42 to irrigate the vegetation.

[0041] Reference Figure 3 and Figure 4 When the vegetation needs watering and the liquid level in the placement trough 3 separates from the bottom of the planting trough 4, the drive cylinder 73 starts and drives the second pressing plate 72 to move along the length of the water storage tank 2 until one end of the second pressing plate 72 presses against the inner wall of the water storage tank 2. At this time, the first pressing plate 71 and the second pressing plate 72 simultaneously seal the opening of the water storage tank 2. The drive motor 74 starts and drives the drive screw 75 to rotate. Under the drive of the drive screw 75 and the limiting guidance of the inner wall of the water storage tank 2, the first pressing plate 71 and the second pressing plate 72 move downward in the vertical direction. Under the action of the first pressing plate 71 and the second pressing plate 72, the rainwater in the water storage tank 2 enters the placement trough 3 through the connecting pipe 5 to water the vegetation in the planting trough 4. The first sealing strip 9 and the second sealing strip 10 reduce the gap between the edges of the first extrusion plate 71 and the second extrusion plate 72 and the inner wall of the water storage tank 2, reducing the possibility of rainwater flowing through the gaps to the top of the first extrusion plate 71 and the second extrusion plate 72. The solar panel 8 absorbs sunlight during the day and converts it into electrical energy to power the drive cylinder 73 and the drive motor 74, improving energy utilization. The filter plate 11 filters impurities in the rainwater, reducing the possibility of impurities clogging the inside of the connecting pipe 5.

[0042] The implementation principle of a building structure for rooftop greening in this embodiment is as follows: During rainfall, rainwater enters the water storage tank 2. The floating ring 62 rises with the increasing water level, and the rain shield 61, pushed by the top rod 63, flips over to cover the planting trough 4, reducing the risk of continuous rainwater inflow and root rot. The rainwater stored in the water storage tank 2 flows into the placement trough 3 via the connecting pipe 5. The rainwater in the placement trough 3 seeps into the planting trough 4 through the seepage holes 42 to irrigate the vegetation.

[0043] When the vegetation needs watering and the liquid level in the placement trough 3 separates from the bottom of the planting trough 4, the drive cylinder 73 starts and drives the second squeezing plate 72 to move. Simultaneously, the first squeezing plate 71 and the second squeezing plate 72 seal the opening of the water storage tank 2. The drive motor 74 starts and drives the first squeezing plate 71 and the second squeezing plate 72 downwards. Under the squeezing action, rainwater enters the placement trough 3 through the connecting pipe 5 to irrigate the vegetation in the planting trough 4. The solar panel 8 absorbs sunlight during the day and converts it into electrical energy, providing power to the drive cylinder 73 and the drive motor 74, thus improving energy utilization.

[0044] 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.
