Technical Field

[0001] The present application relates to the field of roof greening, and in particular to an ecological roof planting structure and a plant cultivation method. Background Art

[0002] With the acceleration of my country's urbanization process, construction land is gradually eroding the limited urban green space. Increasing the urban green space has become an urgent need. In recent years, people have turned their attention to roof greening. Since planting has good thermal insulation, heat insulation and energy-saving effects on buildings, and can purify urban air and reduce the heat island effect, it has attracted more and more attention from all walks of life.

[0003] Traditional roof planting is to lay a soil layer on the roof and then plant green plants on the soil layer to achieve greening of the roof. However, this type of planting roof is not flexible in layout and requires surface treatment of the entire roof, which makes the actual operation more complicated. Summary of the invention

[0004] In order to improve the problem of inflexibility in planting green plants on roofs, the present application provides an ecological roof planting structure and a plant cultivation method.

[0005] On the one hand, the present application provides an ecological roof planting structure adopting the following technical solutions:

[0006] An ecological roof planting structure includes a water tank laid on the roof, wherein a plurality of green plant units are arranged in the water tank, wherein the green plant units are overlapped on the water tank, wherein a water pump is arranged on the water tank, wherein the water pump is used to supply water to the water tank, wherein a water supply unit is arranged in the water tank, wherein the water supply unit is inserted into the green plant units, and wherein a driving unit is arranged on the water tank for driving the water supply unit to supply water to the green plant units.

[0007] By adopting the above technical scheme, when planting green plants on the roof, the water tank is first arranged on the roof, and then a plurality of green plant units are overlapped in the water tank, and the water supply unit is inserted into the green plant unit, and the water pump is driven to supply water to the water tank, and then the water supply unit is driven by the driving unit to spray water onto the green plant unit to water the green plants on the green plant unit. The entire roof green plant area is assembled by a plurality of green plant units, thereby improving the flexibility of planting green plants on the entire roof.

[0008] In a specific possible implementation scheme, the green plant unit includes a planting box, which has a planting soil layer for planting green plants, a drainage hole connected to the water tank is provided on the bottom wall of the planting box, and a filter layer is provided between the planting soil layer and the bottom wall of the planting box.

[0009] By adopting the above technical solution, green plants are planted in the planting box. When it rains, rainwater passes through the planting soil layer, the filter layer and the drainage pipe into the water tank, thereby realizing the collection of rainwater. When the temperature rises, the water in the water tank evaporates and enters the planting soil layer, which effectively prevents the green plants from drying out and withering, thereby realizing the utilization of rainwater. At the same time, the filter layer can effectively prevent the soil of the planting soil layer from falling into the water tank.

[0010] In a specific feasible implementation scheme, the water supply unit includes a water pipe arranged on the bottom wall of the water storage tank, the bottom of the water pipe is provided with a water inlet, the inner wall of the water pipe is hinged with a blocking plate for blocking the water inlet, the water pipe is inserted into the planting box and passes through the planting soil layer, the water pipe passes through the planting soil layer and is provided with a water outlet at one end, a water suction tray is provided in the water pipe, the water suction tray is slidably arranged along the inner wall of the water pipe, a water guide hole is provided on the water suction tray, and a sealing plate for blocking the water guide hole is hinged on the top wall of the water suction tray.

[0011] By adopting the above technical solution, when watering the green plants on the planting soil layer, the water absorption plate is driven to rise, and the baffle rotates to open the water inlet, and the water in the water storage tank enters the water guide pipe from the water inlet, and then the water absorption plate is driven to descend, and the blocking plate rotates, and the water guide hole opens, and water enters the top of the water absorption plate along the water guide hole, and then the water absorption plate is continuously driven to reciprocate up and down, and finally the water flows out from the water outlet, thereby realizing the watering of the green plants.

[0012] In a specific feasible implementation scheme, the driving unit includes a linear motor arranged on the water tank, a driving rod is provided at the output shaft end of the linear motor, the driving rod slides along the length direction of the water tank, a connecting rod is provided on the driving rod, a pumping rod is slidably provided on the water pipe, the pumping rod is inserted into the water pipe from the top inlet of the water pipe and connected to the water suction plate, one end of the connecting rod is hinged to the driving rod, and the other end of the connecting rod is hinged to the pumping rod.

[0013] By adopting the above technical solution, when watering green plants, the linear motor drives the driving rod to reciprocate along the length direction of the water tank. At this time, the driving rod drives the pumping rod to reciprocate up and down along the water pipe. The pumping rod drives the water suction plate to reciprocate up and down in the water pipe, thereby driving the water suction plate so that the water suction plate can suck in and discharge water.

[0014] In a specific feasible implementation scheme, a limit block is provided on the water conduit, a limit groove is provided on the limit block for the pumping rod to be inserted, the pumping rod and the limit block are slidably arranged, a guide groove is provided on the side wall of the limit groove, and the pumping rod is provided with a guide block for sliding in the guide groove.

[0015] By adopting the above technical solution, when the driving rod drives the pumping rod to slide, the pumping rod slides along the limiting groove on the limiting block. At this time, the guide block slides in the guide groove. The sliding of the pumping rod is restricted by the limiting groove and the guide groove, thereby improving the stability of the pumping rod sliding on the water pipe.

[0016] In a specific feasible implementation scheme, a rotating ring is provided on the water conduit, the water outlet is arranged on the rotating ring, a rotating sleeve is provided on the water pumping rod, the rotating sleeve is connected to the rotating ring through a support rod, a spiral groove is provided on the water pumping rod, the spiral groove is arranged along the length direction of the water pumping rod, and the rotating sleeve is provided with an insert block for sliding in the spiral groove.

[0017] By adopting the above technical solution, when the pumping rod slides up and down, the plug slides along the spiral groove and drives the rotating sleeve to rotate. The rotating sleeve drives the rotating ring to rotate through the support rod. When water flows out from the water outlet on the rotating ring, the rotating ring throws the water out of the water outlet by rotating, thereby increasing the irrigation range of the water pipe for the green plants. At the same time, by controlling the amplitude of the reciprocating motion of the linear motor, the irrigation range of the green plants can be adjusted, thereby improving the convenience of adjusting the irrigation range.

[0018] In a specific feasible implementation scheme, a driving ring is provided on the pumping rod, the driving ring is sleeved on the water pipe and slidably arranged with the water pipe, a bulldozer plate is hinged on the water pipe, a connecting plate for driving the bulldozer plate to rotate is hinged on the driving ring, and the connecting plate is hinged to the bulldozer plate.

[0019] By adopting the above technical solution, when the pumping rod moves upward, the pumping rod pushes the driving ring to slide upward along the water pipe, the driving ring pushes the connecting plate to move and rotate, and the connecting plate pushes the bulldozer plate to reverse in the direction away from the water pipe, so that the bulldozer plate pushes the planting soil layer around the water pipe to crack, effectively avoiding the hardening of the planting soil layer.

[0020] In a specific possible implementation mode, the driving ring is provided with a bulldozing surface for pushing soil to move in a direction away from the water conduit.

[0021] By adopting the above technical solution, when the pumping rod moves downward, the bulldozer surface on the drive ring can push the soil under the drive ring to one side, thereby reducing the resistance of the drive ring when it moves downward and improving the convenience of moving the drive ring.

[0022] In a specific feasible implementation scheme, a drain pipe is provided on the side wall of the water tank, a solenoid valve is provided on the drain pipe, a control cylinder is provided in the water tank, an inner cavity of the control cylinder is connected to the water tank, a float plate is slidably provided in the control cylinder, an electric connector 1 is provided on the float plate, an electric connector 2 for contacting the electric connector 1 is provided on the control cylinder, a battery is provided on the water tank, the electric connector 1 is electrically connected to the positive pole of the solenoid valve through a wire, the electric connector 2 is electrically connected to the positive pole of the battery through a wire, and the negative pole of the solenoid valve is electrically connected to the negative pole of the battery through a guide.

[0023] By adopting the above technical solution, when it rains, rainwater flows into the water tank through the planting soil layer and the filter layer, and the water enters the control cylinder. As the amount of rain increases, the water level in the water tank continues to rise, and the water drives the float to move upward in the control cylinder. When the water in the water tank reaches a certain height, the electrical connector 1 on the float contacts the electrical connector 2 in the control cylinder, thereby forming a circuit between the battery and the solenoid valve. The battery supplies power to the solenoid valve, and at this time the solenoid valve opens, and the water in the water tank is discharged from the drain pipe, causing the water level to drop below the planting soil layer, thereby effectively preventing the green plants in the planting soil layer from dying due to excessive water accumulation.

[0024] On the other hand, the present application provides an ecological roof planting plant cultivation method using the following technical solution:

[0025] An ecological roof plant cultivation method comprises the following steps:

[0026] S1. Site laying: Place the planting boxes one by one into the water storage tank, insert the water supply unit into the planting box, and lay a planting soil layer on the filter layer;

[0027] S2, planting, planting green plant seeds or seedlings in the planting soil layer;

[0028] S3, maintenance, driving the water supply unit through the driving unit to water the green plants in the planting soil layer and apply fertilizers.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. When laying green plants on the roof, first lay the water tank on the roof, then install several green plant units in the water tank by overlapping, transfer water to the water tank through a water pump, and irrigate the green plants in the green plant unit with the water in the water tank by driving the water supply unit through the driving unit, so as to ensure the water supply of the green plants, and complete the planting of roof green plants by splicing several green plant units, thereby improving the flexibility of roof green plant planting;

[0031] 2. When irrigating green plants, the linear motor drives the driving rod to move back and forth, and the connecting rod and the pumping rod drive the water suction plate to move back and forth along the water pipe, so that the water in the water storage tank can be discharged from the water outlet to irrigate the green plants. When the pumping rod moves up and down, the plug block cooperates with the spiral groove to drive the rotating ring to rotate, and the rotating ring throws out the water at the water outlet, thereby increasing the irrigation range of the water pipe. When the pumping rod moves up and down, the driving ring and the connecting plate drive the bulldozer to reverse upward to achieve the plowing of the planting soil layer, effectively avoiding the hardening of the planting soil layer;

[0032] 3. When it rains, rainwater flows from the planting soil layer and the filter layer into the water tank for storage, and is used to irrigate the green plants again through the water pipe, thereby making full use of rainwater and saving water resources. At the same time, when the rainwater in the water tank continues to rise, the float rises with the rise of the water level. When the rainwater in the water tank submerges the planting soil layer, the electrical connector 1 on the float contacts the electrical connector 2, and a passage is formed between the battery and the solenoid valve. The solenoid valve opens, and the accumulated water in the water tank is discharged from the drain pipe, so that the water level in the water tank drops below the planting soil layer, thereby effectively avoiding the drowning of green plants due to excessive rainwater in the water tank.

The part of the pumping rod 35 inserted into the water guide pipe 31 is a round rod 353, and the round rod 353 is fixedly connected to the water suction plate 33.

[0049] Reference Figure 1 , Figure 2 The driving unit 4 in this embodiment includes a linear motor 41 arranged on the water tank 11, and a driving rod 42 is fixedly provided on the output shaft of the linear motor 41. The driving rod 42 is a square rod. The driving rod 42 passes through the opposite side walls of the water tank 11 in sequence and is slidably arranged on the water tank 11. A connecting rod 43 is hinged on the driving rod 42. The connecting rod 43 corresponds to the water pipe 31 one by one, and the end of the connecting rod 43 away from the driving rod 42 is hinged to the pumping rod 35.

[0050] Reference Figure 3 , Figure 6 A rotating ring 361 is rotatably provided on the end wall of the circular tube 312, a connecting ring 362 is provided at the bottom of the rotating ring 361, a connecting groove 363 for inserting the connecting ring 362 is provided on the end wall of the circular tube 312, and the connecting groove 363 is a dovetail groove.

The rotating sleeve 365 is fixedly connected to the rotating ring 361 through a supporting rod, and a water outlet 367 is provided on the rotating ring 361.

[0051] Reference Figure 2 , Figure 7A sliding groove 371 is provided on the outer wall of the rectangular tube 311, and the sliding groove 371 is arranged in the vertical direction. The sliding groove 371 is arranged in the planting soil layer 24. A driving ring 372 sliding in the sliding groove 371 is sleeved on the rectangular tube 311, and a bulldozer surface 373 is provided at the bottom of the driving ring 372. The bulldozer surface 373 is inclined from the side of the driving ring 372 away from the bottom wall of the sliding groove 371 toward the side close to the bottom wall of the sliding groove 371. The driving ring 372 is fixedly connected to the pumping rod 35. Three bulldozer plates 374 are hinged on the bottom wall of the sliding groove 371. A connecting plate 375 is hinged on the driving ring 372. The connecting plate 375 corresponds to the bulldozer plate 374 one by one. One end of the connecting rod 43 and one end of the bulldozer plate 374 are rotatably arranged through a rotating shaft.

[0052] When irrigating the green plants 25, the linear motor 41 is turned on, and the linear motor 41 drives the driving rod 42 to move back and forth along the length direction of the water tank 11. The driving rod 42 drives the pumping rod 35 to slide up and down along the water pipe 31 through the connecting rod 43. At the same time, the pumping rod 35 slides in the limiting groove 342, and the guide block 351 slides in the guide groove 352. The sliding of the pumping rod 35 is restricted by the limiting groove 342 and the guide groove 352, so that the stability of the pumping rod 35 sliding on the water pipe 31 is improved.

[0053] When the pumping rod 35 slides upward, the pumping rod 35 drives the water absorption plate 33 to slide upward. At this time, the blocking piece 322 rotates, the water inlet 321 opens, and the water absorption plate 33 absorbs the water in the water storage tank 11 into the water guide pipe 31. When the pumping rod 35 moves downward, the pumping rod 35 drives the water absorption plate 33 to move downward. At this time, the blocking piece 322 blocks the water inlet 321, the blocking piece 332 rotates, the water guide hole 331 opens, and the water under the water absorption plate 33 flows into the upper part through the water guide hole 331. As the pumping rod 35 continues to move up and down, the water in the water storage tank 11 is continuously pumped upward, and at the same time As the pumping rod 35 continues to move up and down, the plug block 366 in the rotating sleeve 365 slides along the spiral groove 364 and drives the rotating sleeve 365 to rotate. The rotating sleeve 365 drives the rotating ring 361 to rotate through the support rod, and the water in the water pipe 31 is discharged through the water outlet 367. At the same time, the water at the water outlet 367 is thrown out by the rotation of the rotating ring 361, and by controlling the frequency of the reciprocating motion of the linear motor 41, the distance at which the water is thrown out at the water outlet 367 can be adjusted, thereby realizing the adjustment of the irrigation area of ​​the green plants 25 while irrigating the green plants 25.

[0054] When the pumping rod 35 slides upward, the pumping rod 35 drives the driving ring 372 to slide in the sliding groove 371. While the sliding groove 371 slides upward, it pushes the bulldozer plate 374 to flip outward through the connecting plate 375. The bulldozer plate 374 pushes the planting soil layer 24 around the water pipe 31 to move upward, thereby realizing the tillage of the planting soil layer 24 and effectively avoiding the hardening of the planting soil layer 24. When the driving ring 372 slides down, the bulldozer surface 373 pushes the soil under the driving ring 372 to one side, thereby reducing the increased resistance of the soil when the driving ring 372 moves downward.

[0055] Reference Figure 8 , Fig. 9 Each water storage tank 11 is provided with a drain pipe 51 on the side away from the linear motor 41. The lowest point of the drain pipe 51 is flush with the bottom wall of the planting box 21. A solenoid valve 52 is provided on the drain pipe 51. A battery 53 is provided on the outer wall of the water storage tank 11. A control cylinder 54 is provided in the side wall of the water storage tank 11. The lower port of the control cylinder 54 is connected to the water storage tank 11. A rain shield 55 is provided at the upper port of the control cylinder 54. An exhaust port 56 is provided below the rain shield 55. The control cylinder 54 A floating plate 57 is provided inside the slide, an electric connector 58 is provided on the floating plate 57, an electric connector 59 is provided inside the control tube 54, the electric connector 59 is located in the middle of the planting soil layer 24, the electric connector 58 and the electric connector 59 are electrically connected by plugging, the electric connector 58 is electrically connected to the positive pole of the solenoid valve 52 through a wire, the electric connector 59 is electrically connected to the positive pole of the battery 53 through a wire, and the negative pole of the solenoid valve 52 is electrically connected to the negative pole of the battery 53 through a wire.

[0056] When the rainy season comes, rainwater flows into the water tank 11 through the planting soil layer 24 and the filter layer 23. As the rainwater continues to accumulate, the water level in the water tank 11 continues to rise. At this time, the water level in the control cylinder 54 is constantly rising, and the float 57 rises with the water level. When the water level in the water tank 11 rises to the middle position of the planting soil layer 24, the accumulated water has affected the survival of the green plants 25. At this time, the electrical connector 1 58 is inserted into the electrical connector 2 59 and electrically connected to the electrical connector 2 59, so that a passage is formed between the battery 53 and the solenoid valve 52. At this time, the solenoid valve 52 is opened, and the accumulated water in the water tank 11 is discharged from the drain pipe 51, and the water level in the water tank 11 drops below the planting soil layer 24, thereby effectively preventing the accumulated water in the water tank 11 from drowning the green plants 25 and improving the timeliness of rainwater drainage in the water tank 11.

[0057] The implementation principle of an ecological roof planting structure in an embodiment of the present application is as follows: when planting green plants 25 on the roof 1, first arrange the water tank 11 on the roof 1, then overlap a plurality of green plant units 2 on the water tank 11, and insert the water supply unit 3 into the green plant unit 2, drive the water pump 12 to supply water to the water tank 11, and then drive the water supply unit 3 through the driving unit 4 to spray water onto the green plant unit 2, and water the green plants 25 on the green plant unit 2, and assemble a plurality of green plant units 2 into a green plant 25 area on the entire roof 1, thereby improving the flexibility of planting green plants 25 on the entire roof 1.

[0061] S3, maintenance, driving the water supply unit 3 through the driving unit 4 to water the green plants 25 in the planting soil layer 24 and apply fertilizers.

[0062] In step S1, before laying the planting soil layer 24, a channel for inserting the water supply unit 3 is reserved through the branch pipe, and then the planting soil layer 24 is laid. The planting soil layer 24 uses lightweight improved soil or inorganic planting soil. The improved soil should be prepared in the following ratio: garden soil, rice husk, and leaf mold in a ratio of 1:1:1. The planting soil layer 24 is 20 mm lower than the top wall of the planting box 21;

[0063] In step S2, the green plants 25 are selected from ground cover and small trees. When planting the ground cover, the seeds are sprinkled in the planting soil layer 24, and then covered with planting soil on one side. Watering is performed every two days and fertilization is performed once a month. When cultivating small trees, the tree seedlings are selected to be transplanted into the planting soil layer 24 and then fixed.

[0064] In step S3, after watering and fertilizing the ground cover and trees regularly, the ground cover is pruned every 10 days and the trees are pruned regularly every year, which effectively avoids excessive growth of the ground cover and trees while ensuring the beauty of the green plants 25 on the roof 1.

[0065] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
