Abstract
Description
Technical Field
[0001] This utility model relates to the field of roof greening technology, specifically a roof greening water supply and drainage device. Background Technology
[0002] Roof greening refers to creating a green environment on the exterior of a building by directly or indirectly attaching an environment suitable for the growth of green plants. It can use green plants to insulate and protect the roof, improve the environment, enhance aesthetics, and save energy. Roof greening is a form of green space that mainly uses plants to cover the roof. Because roof greening is isolated from the ground, it is inconvenient to irrigate it. Therefore, the design of water supply and drainage for roof plants is particularly important.
[0003] A rooftop greening water supply and drainage device disclosed in Chinese utility model patent application CN 223110731U, although it can improve the uniformity and range of spraying by repeatedly adjusting the spraying angle through a set water spraying mechanism and adjustment mechanism, thereby improving the spraying efficiency, is prone to waterlogging when there is too much rainfall in a short period of time, resulting in too much water stored on the roof. It cannot form an effective system, that is, to store water when there is abundant rainfall and to distribute and replenish water in case of insufficient rainfall. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figures 1 to 5 This utility model provides a technical solution: a roof greening water supply and drainage device, including a roof 1, a green lawn 2 planted on the top of the roof 1, a high support box 4 installed on one side of the top of the roof 1 through a support column 3, and a low support box 5 installed on the other side of the top of the roof 1 through a water tank 6. The bottoms of the high support box 4 and the low support box 5 are fixed by bolts. A winding drum 12 and a water spray pipe 11 are arranged at equal intervals between the high support box 4 and the low support box 5. Inside the take-up drum 12, a take-up shaft 13 is connected via a bearing. A rainproof cloth 14 is wound around the outside of the take-up shaft 13. The movable end of the rainproof cloth 14 passes through the side wall of the take-up drum 12 and is fixedly connected to a pull rod 15. By pulling out the pull rod 15, the rainproof cloth 14 can be unfolded. The length of the rainproof cloth 14 pulled out is the same as the distance between the take-up drum 12, thereby using the rainproof cloth 14 to cover the green lawn 2 and prevent excessive rainwater from causing waterlogging.
[0017] Both ends of the pull rod 15 are fixedly connected to the connecting rod 20. The high support box 4 and the low support box 5 are slidably connected to the toothed rod 24. The middle part of the toothed rod 24 is connected to the connecting rod 20 through the sliding rod 19. The side walls of the high support box 4 and the low support box 5 are provided with sliding grooves 18 for the sliding rod 19 to slide.
[0018] Both ends of the take-up shaft 13 pass through the take-up drum 12 and are fixedly connected to gears 23 that mesh with the rack 24. The surfaces of the rack 24 and the gears 23 are lubricated with grease. The diameter of the gears 23 is the same as the diameter of the take-up shaft 13, ensuring that the linear velocity of the edges of the take-up shaft 13 and the gears 23 is the same when they rotate. A rectangular groove is provided at the bottom of the high support box 4, and an adjustment handle 7 connected to the rack 24 is provided inside the rectangular groove.
[0019] By setting the pull rod 15, the rainproof cloth 14 inside the winding drum 12 can be pulled out. When the rain is too heavy, it can form a rain shelter on the roof 1 to prevent a large amount of rainwater from falling on the roof 1 and forming water accumulation, thereby achieving the purpose of providing a good environment for the growth of the green lawn 2.
[0020] A filter screen 16 is installed in the opening on one side of the top of the water tank 6 to receive rainwater. A water pipe 25 is connected to the bottom of the water tank 6. A water valve 21 is installed in the middle of the water pipe 25. When it does not rain for a long time, the water inside the water tank 6 can be replenished by opening the water valve 21.
[0021] The bottom of the water tank 6 is connected to a water pump 22, the end of the water pump 22 is connected to a water pump 8, the outlet of the water pump 8 is connected to a high-pressure water pipe 17, the high-pressure water pipe 17 is connected to each spray pipe 11, and the bottom of the spray pipe 11 is provided with a spray hole.
[0022] The side wall of the water tank 6 is provided with an overflow port 9, and the outer wall of the water tank 6 is provided with an overflow pipe 10. When the amount of rainwater is too large, more water enters the water tank 6. After the liquid level reaches the overflow port 9, the water inside the water tank 6 can be discharged from the overflow port 9.
[0023] By setting up a water tank 6, rainwater can be collected inside the water tank 6 by pulling out the rainproof cloth 14 when there is a lot of rain. When there is less rain, the water stored inside the water tank 6 can be pumped out by the water pump 8 for spraying and irrigation by the water pipe 11. Furthermore, when there is little water in the water tank 6, water can be added by opening the water valve 21, thereby achieving the purpose of water distribution.
[0024] Working principle: In use, when it rains, the toothed rod 24 is moved by adjusting the handle 7. The bottom of the toothed rod 24 meshes with the gear 23, which can drive the gear 23 to rotate. Through the transmission of the take-up shaft 13, the gear 23 inside the low support box 5 can drive the toothed rod 24 to move, so that the sliding rod 19 slides inside the sliding groove 18. The connecting rod 20 drives the two ends of the pull rod 15 to pull out the rainproof cloth 14. Since the diameter of the gear 23 is the same as the diameter of the take-up shaft 13, the linear speed of the rotation of the edge of the gear 23 is the same as the speed at which the rainproof cloth 14 is pulled out, which makes it easy to use the rainproof cloth 14 to close the top of the roof 1. After rainwater falls on the rainproof cloth 14, the rainwater can be concentrated on one side of the low support box 5 because the low support box 5 is lower. After the rainwater falls on the filter screen 16, it is filtered by the filter screen 16 and stored inside the water tank 6. When too much rainwater is stored, the rainwater overflows from the overflow port 9 and is discharged through the overflow pipe 10. When the rainproof cloth 14 needs to be retracted, by moving the adjusting handle 7 to its original position, the gear 23 can drive the winding shaft 13 to retract the rainproof cloth 14 through reverse operation, so that the green lawn 2 can be exposed to sunlight. When it is necessary to use the sprinkler pipe 11 to irrigate the lawn, the water pump 8 is powered on, and the water is drawn out of the water tank 6 through the water suction pipe 22 and sent into the sprinkler pipe 11 through the high pressure water pipe 17, and sprayed out from the sprinkler hole to achieve the purpose of irrigating the lawn. When the water stored inside the water tank 6 is insufficient, the water is pumped into the water tank 6 by opening the water valve 21, thereby replenishing the water inside the water tank 6.
[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
