[0002] Rooftop gardening is a form of greening and landscaping design on the top of a building. It can increase the green area of ​​the city and improve the urban environment. Due to the rapid water loss of rooftop gardening, in recent years, rooftop gardening design has tended to focus on environmental protection and energy conservation, using environmentally friendly building materials and plant varieties, and setting up environmental protection facilities such as rainwater collection systems.

[0003] Existing roof greening irrigation devices are often used in daily watering of roof gardens. For example, China's authorized patent for a roof greening irrigation device (application number: CN202110131982.8) discloses a roof greening irrigation device, including an irrigation system, a rainwater diversion system, a rainwater collector and a rainwater storage tank. When the rain is heavy, the rainwater diversion system can be used to reduce the impact of rainwater on plant greening and direct irrigation of plants. At the same time, the rainwater collector and the rainwater storage tank are used to store rainwater for subsequent irrigation operations of the irrigation system.

[0004] Although the existing technology can effectively reduce the impact of rainwater on green plants and direct irrigation of plants by rainwater by setting up a rainwater diversion system to avoid over-irrigation, there is a problem that when rainy weather comes, it is difficult for staff to respond in time to start the rainwater diversion system to protect the plants, resulting in a decrease in the protection effect of the rainwater diversion system on plants, causing damage and impact on the roof garden landscape.

A driving screw 6 and an auxiliary rod are respectively installed at both ends of the sliding plate 5.

The driving motor 7 is fixedly installed on the inner wall of the driving box, and the driving box is symmetrically fixedly installed on the top of the lifting base 3. Auxiliary components are arranged inside the driving box, and the model of the driving motor 7 is 80A6S-M02430.

[0032] See also Figures 2 to 4 As shown, the sensing component includes a sensing box 8 arranged at the top of the lifting base 3, a rain collecting plate 9 is fixedly installed on the top of the sensing box 8, and a pair of guide arc plates 10 are fixedly installed on the bottom end of the inner wall of the sensing box 8, which can limit the moving trajectory of the floating ball 11 to avoid the horizontal deviation of the floating ball 11 driven by the water flow, which makes it difficult for the floating ball 11 to normally block the light signal. The floating ball 11 is slidably installed on the inner wall of the guide arc plate 10, and the bottom end of the floating ball 11 is connected to the bottom end of the inner wall of the sensing box 8 by a thin rope. The optical signal transmitting device and the optical signal receiving device are respectively installed on both sides of the inner wall of the sensing box 8. A drainage hole 13 is opened on one side of the sensing box 8, and a drainage hole 13 is arranged on one side of the drainage hole 13. The rain collecting component, by setting a sensing component, can respond to the rainy weather in time when the rainy weather lasts for a long time or the rain is heavy, through the cooperation of the float 11, the optical signal transmitting device and the optical signal receiving device set in the sensing box 8, and drive the rain isolation mechanism to protect the plants on the surface of the landscape base 1, thereby avoiding the problem that when the rainy weather comes, the staff is difficult to respond in time and start the rainwater diversion system to protect the plants, thereby causing the rainwater diversion system to reduce the protection effect of the plants and causing damage and influence on the roof garden landscape, thereby improving the protection effect of the rain isolation mechanism on the roof garden landscape, thereby improving the growth effect and greening effect of the roof garden landscape.

[0033] See also Figures 2 to 4 As shown, the drainage hole 13 is composed of a long and narrow through hole and a short and wide through hole. The horizontal height of the bottom end of the short and wide through hole is equal to the maximum horizontal height of the float 11. The bottom end of the drainage hole 13 is set as a short and wide through hole to increase the rain collection speed in the sensing box 8, thereby improving the sensitivity of the sensing component to respond to rainy weather. The top of the drainage hole 13 is set as a long and narrow through hole, which can increase the outflow speed of rainwater in the sensing box 8 after the rainy weather ends, thereby reducing the blocking time of the first rainproof cloth 4 on the surface of the landscape base 1, thereby reducing the blocking time of sunlight and improving the growth effect of the roof garden landscape.

[0034] Embodiment 2

[0035] See also Figures 1 to 3 As shown, in contrast to Example 1, as another embodiment of the present invention, the adjustment component includes a telescopic connecting rod group 14 arranged at the top of the landscape base 1, and two telescopic connecting rod groups 14 are symmetrically installed. A fixed seat 15 is rotatably installed on one side of the bottom end of the telescopic connecting rod group 14, and the bottom end of the fixed seat 15 is fixedly installed on the top of the landscape base 1, and a sliding seat 16 is rotatably installed on the other side of the bottom end of the telescopic connecting rod group 14. The inner wall of the sliding seat 16 is threaded with a bidirectional screw rod 17, and one end of the bidirectional screw rod 17 can be provided with a hand wheel, a servo motor or other rotating driving device. By setting the adjustment component, after the roof garden landscape grows to a certain height, the staff can use a hand wheel, a servo motor or other rotating driving device to drive the bidirectional screw rod 17 to rotate, so that the bidirectional screw rod 17 drives the rainproof mechanism to move through the sliding seat 16, the telescopic connecting rod group 14 and the lifting base 3, thereby avoiding the problem of hindering the movement of the sliding plate 5 and causing motion interference when the roof garden landscape grows to a certain height, thereby improving the stability and applicability of the device.

[0036] See also Figures 1 to 3 , Figure 5 and Figure 6 As shown, the rain collecting assembly includes a drainage rod 18 arranged on one side of the drainage hole 13, a start box 19 is fixedly installed on one end of the drainage rod 18 away from the induction box 8, a second drainage hole 13 is opened on one side of the start box 19, a box top 20 is fixedly installed on the top of the start box 19, a driving plate 21 is slidably installed on the inner wall of the start box 19, the bottom end of the driving plate 21 is connected to the bottom end of the inner wall of the start box 19 through a spring 22, a connecting block 23 is fixedly installed on the bottom end of one side of the driving plate 21, a toothed plate 24 is fixedly installed on the top of one side of the connecting block 23, and the toothed plate 24 is fixedly installed on the top of one side of the connecting block 23. A signal component is provided on the outer wall, a gear 25 is meshedly installed on one side of the toothed plate 24, a rotating rod is fixedly installed on one end of the gear 25, a baffle plate 26 is fixedly installed on the outer wall of the rotating rod, and the baffle plate 26 is rotatably installed on the top of the water storage tank 2. By arranging a rain collecting component, when the rainy weather lasts for a long time or the rain is heavy, the gravity of the rainwater flowing into the drainage rod 18 drives the driving plate 21 to move, so that the driving plate 21 drives the baffle plate 26 to rotate through the connecting block 23, the toothed plate 24 and the gear 25, so that the water storage tank 2 starts to collect rainwater.

[0037] In summary, by cooperating with the rainwater collecting component and the irrigation mechanism, rainwater can be collected by the water storage tank 2 when the rainy weather lasts for a long time or the rain is heavy. When it does not rain for a long time and the roof garden landscape needs to be watered, the staff can start the irrigation system and use the rainwater stored in the water storage tank 2 to water the plants on the surface of the landscape base 1 through the water pipe and the atomizing sprinkler.

[0038] See also Figure 5 and Figure 6 As shown, the signal component includes a shell 27 arranged on the outer wall of the toothed plate 24, the shell 27 is fixedly installed on the top of the water tank 2, and a pressure sensor 28 is fixedly installed on the top of the inner wall of the shell 27. By setting the signal component, when there is no rainfall for a long time, the rainwater in the start box 19 can evaporate continuously, so that the spring 22 releases elastic potential energy and undergoes elastic deformation to push the drive plate 21, so that the drive plate 21 drives the toothed plate 24 to move through the connecting block 23, so that the toothed plate 24 squeezes the pressure sensor 28, so that the pressure sensor 28 sends a signal to notify the staff, so that the staff can timely irrigate the roof garden landscape through the irrigation mechanism, wherein the pressure sensor 28 sends a signal for notification can be to control the set lighting components or audio equipment to notify the staff, or to notify and warn through a mobile phone program.

[0039] See also Figure 2 , Figure 3 and Figure 5 As shown, ventilation grooves are evenly opened on both sides of the box top 20, and eaves are fixedly installed on the top of the ventilation grooves, which can slow down the evaporation rate of rainwater in the start box 19, so that the evaporation rate of rainwater in the start box 19 is more in line with the evaporation rate of water in the roof garden landscape soil, thereby making the effect of artificial irrigation more accurate and effective.

[0040] See also Figure 2 and Figure 3 As shown, the auxiliary component includes a second rainproof cloth 29 arranged in the driving box, the second rainproof cloth 29 is all wound around the outer wall of the auxiliary torsion shaft 30, one end of the second rainproof cloth 29 is all fixedly installed on one side of the fixing rod 31, and the fixing rod 31 is all fixedly installed on one end of the sliding plate 5. By setting up the auxiliary component, when the rainproof mechanism protects the roof garden landscape, the sliding plate 5 can drive the fixing rod 31 to move, so that the fixing rod 31 drives one end of the second rainproof cloth 29 to move, so that the second rainproof cloth 29 forms a vertical rainproof barrier on both sides of the first rainproof cloth 4, further improving the protection effect of the plants at the top of the landscape base 1.

[0041] See also Figures 1 to 3 As shown, the tops of the driving screw rod 6 and the bidirectional screw rod 17 are both provided with rainproof half-cylinders, which can protect the driving screw rod 6 and the bidirectional screw rod 17 in rainy weather, and prevent rainwater from falling directly on the surface of the driving screw rod 6 and the bidirectional screw rod 17, corroding the threads on the surface of the driving screw rod 6 and the bidirectional screw rod 17, thereby shortening the service life of the driving screw rod 6 and the bidirectional screw rod 17, and improving the service life of the driving screw rod 6 and the bidirectional screw rod 17.

[0042] See also Figure 5 and Figure 6As shown, the distance from the top of the inner wall of the shell 27 to the gear 25 is greater than the minimum distance from the bottom of the tooth block part on one side of the toothed plate 24 to the top of the inside of the shell 27. After the toothed plate 24 drives the blocking plate 26 to rotate and close through the gear 25, a gap is left between the top of the toothed plate 24 and the pressure sensor 28, thereby avoiding the problem of the toothed plate 24 directly squeezing the pressure sensor 28 after closing the blocking plate 26, thereby transmitting an erroneous signal to the staff, thereby improving the stability and reliability of the device.

[0043] Working principle: When the rainy weather lasts for a long time or the rain is heavy, the rainwater in the induction box 8 accumulates continuously. At this time, the rainwater in the induction box 8 drives the float 11 to move upward. When the float 11 moves between the optical signal transmitting device and the optical signal receiving device, the float 11 prevents the optical signal receiving device from receiving the optical signal emitted by the optical signal transmitting device. At this time, the optical signal receiving device sends a signal to control the drive motor 7 to start, so that the drive motor 7 drives the drive screw 6 to rotate, and the drive screw 6 drives the sliding plate 5 to move away from the drive motor 7. The sliding plate 5 drives one end of the first rainproof cloth 4 to move, so that the first rainproof cloth 4 covers the top of the landscape base 1, preventing rainwater from directly irrigating the plants on the top of the landscape base 1. At the same time, the sliding plate 5 drives the fixed rod 31 to move, and the fixed rod 31 carries One end of the second rainproof cloth 29 is moved, so that the second rainproof cloth 29 forms a vertical rainproof barrier on both sides of the first rainproof cloth 4, further improving the protection effect of the plants on the top of the landscape base 1. At the same time, the rainwater in the sensing box 8 flows into the starting box 19 through the drainage hole 13 and the drainage rod 18, so that the driving plate 21 moves toward the direction close to the spring 22 under the gravity of the rainwater. At this time, the driving plate 21 squeezes the spring 22, so that the spring 22 accumulates elastic potential energy and undergoes elastic deformation. At the same time, the driving plate 21 drives the connecting block 23 to move, and the connecting block 23 drives the toothed plate 24 to move. The toothed plate 24 drives the gear 25 to rotate, so that the gear 25 drives the blocking plate 26 to rotate, so that the blocking plate 26 stops blocking the inside of the water storage tank 2 from the outside, and then the water storage tank 2 starts to collect rainwater;

[0044] When the rain decreases or stops, the rainwater inside the induction box 8 continuously flows into the start box 19 through the drainage hole 13 and the drainage rod 18. At this time, the float 11 moves downward as the water level drops, so that the optical signal receiving device starts to receive the optical signal emitted by the optical signal transmitting device again. At this time, the optical signal receiving device sends a signal to control the drive motor 7 to start in reverse, so that the drive motor 7 drives the rainproof mechanism and the auxiliary components to reset through the driving screw 6 and the sliding plate 5. At this time, the rainwater in the start box 19 flows out through the second drainage hole 13. When the rainwater in the start box 19 drops to the bottom of the second drainage hole 13, the spring 22 releases its elastic potential energy and undergoes elastic deformation to push the drive plate 21 to move, so that the drive plate 21 drives the baffle plate 26 to reset through the connecting block 23, the toothed plate 24 and the gear 25, so that the baffle plate 26 blocks the rainwater in the water storage tank 2 from the external environment, thereby preventing foreign matter in the external environment from contaminating the rainwater stored in the water storage tank 2.

[0045] When there is no rainfall for a long period of time, the rainwater in the start box 19 slowly evaporates and escapes through the box top 20. At this time, the spring 22 continuously releases elastic potential energy, undergoes elastic deformation, and pushes the drive plate 21 to move toward the box top 20. The drive plate 21 drives the connecting block 23 to move, and the connecting block 23 drives the toothed plate 24 to move, so that the toothed plate 24 squeezes the pressure sensor 28, so that the pressure sensor 28 sends a signal to notify the staff to carry out manual watering. At this time, the staff can start the watering system and use the rainwater stored in the water tank 2 to water the plants on the surface of the landscape base 1 through the water pipe and the atomizing sprinkler;

[0046] When the plants on the surface of the landscape base 1 grow, the staff can rotate the bidirectional screw rod 17 through a rotating device such as a handle according to the actual situation of the plants. The bidirectional screw rod 17 drives the sliding seat 16 to move toward the direction close to the midpoint of the landscape base 1. The sliding seat 16 drives the telescopic connecting rod group 14 to bend and stretch, so that the telescopic connecting rod group 14 drives the lifting base 3 to move upward, thereby completing the height adjustment of the rainproof mechanism.

[0047] Other technologies of this embodiment adopt existing technologies.
