Description

Technical Field

[0001] The present application relates to the technical field of roof construction, and in particular to a non-walkable green roof structure. Background Art

[0002] Green roof is based on the characteristics of relatively small building load, using lawns, ground covers, small shrubs and climbing plants to cover the roof and underground building top plate. There can be paths and courtyards on the roof for people to walk and stay.

[0003] The existing patent (Announcement No.: CN212926737U) discloses a non-walkable green roof structure, including a roof structure layer, a waterproof and thermal insulation layer, a protective isolation layer, a solid water storage layer, a soil barrier layer, a soil barrier baffle, a soil layer, a plant layer and a pedestrian area. The plant layer includes herbaceous plant seeds and Crassulaceae plant seedlings. The utility model is an energy-saving and environmentally friendly system for a non-walkable green roof structure that uses plants planted on the roof top plate to block solar energy to prevent overheating of the room. The principle is to form an overall covering roof system that is heat-insulating, impermeable, environmentally friendly and energy-saving by laying various layers such as protective isolation, water storage layer, soil barrier layer, soil barrier layer and plant layer. The utility model has the characteristics of fast construction speed, low cost, light weight, almost no maintenance and low inspection frequency.

[0004] The above-mentioned non-walkable green roof structure has a relatively complicated construction process during use. The rainwater is first collected in a water storage tank, and then flows into the drainage trough through the drainage holes after saturation. This makes it impossible to achieve uniform irrigation of the surface of the plants and the top soil with rainwater after the subsequent rainy season ends, and manual intervention is often required for irrigation and maintenance. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present application provides a non-walkable green roof structure, which has the advantages of fully utilizing rainwater and uniform irrigation, and solves the problem of inability to fully utilize rainwater resulting in cumbersome maintenance.

The outer surface of each planting box is fixedly connected to a plurality of water diversion grooves, and a water-absorbing sponge is clamped inside each water diversion groove.

[0008] Through the above scheme, the water filter plate is set to achieve the purpose of filtering rainwater, and the rainwater collection effect is achieved in conjunction with the water storage tank. When the rainwater saturates the planting box, the rainwater is sucked into the planting box by capillary force through the absorbent sponge, which can achieve continuous moisturizing of the soil and prevent the soil inside the planting box from losing into the water storage tank. By setting the linkage of the threaded rod and the eccentric disk, the irrigation pipe can move at a uniform speed above the planting box and spray water mist, thereby achieving uniform irrigation of the surface of the plants and the top soil, and improving the utilization rate of rainwater.

[0009] Furthermore, the other ends of the two water outlet pipes are fixedly connected to a bellows, and the other ends of the two bellows are fixedly connected to an irrigation pipe.

[0011] Furthermore, the threaded rod and the right end of the transmission shaft are both fixedly connected with sprockets, and the two sprockets are connected through chain transmission.

[0012] Through the above scheme, by setting the sprocket and the chain, the purpose of transmitting power for the rotation of the reciprocating shaft can be achieved.

[0013] Furthermore, a plurality of drainage holes are provided on the outer surface of the guard plate, and the plurality of drainage holes are all located at the bottom end of the side wall of the guard plate.

[0014] Through the above scheme and the provision of drainage holes, it is possible to avoid the situation where the plants are submerged when the rainfall is too heavy.

[0015] Furthermore, the diameter of the sprocket located at the top is larger than the diameter of the sprocket located at the bottom, and the left end of the threaded rod is fixedly connected to the output end of the external forward and reverse motor.

[0019] Furthermore, a plurality of water filter holes are provided on the upper surface of the water filter plate, and the plurality of water filter holes are arranged in a matrix.

[0034] See also Figure 4 and Figure 5A water filter plate 19 is placed on the upper surface of the water storage tank 1, and a plurality of planting boxes 20 are inserted on the upper surface of the water filter plate 19.

[0035] In this embodiment, a non-walkable green roof structure can achieve the purpose of filtering rainwater by setting a water filter plate 19, and achieves the effect of collecting rainwater in cooperation with the water storage tank 1. When the rainwater saturates the planting box 20, the rainwater is sucked into the planting box 20 by capillary force through the absorbent sponge 22, which can achieve continuous moisturizing of the soil and prevent the soil inside the planting box 20 from losing into the water storage tank 1. By setting the linkage of the threaded rod 3 and the eccentric disk 9, the irrigation pipe 5 can move at a uniform speed above the planting box 20 and spray water mist, thereby achieving uniform irrigation of the surface of the plants and the top soil, and improving the utilization rate of rainwater.

[0036] It should be noted that artificial turf can be laid on the upper surface of the water filter plate 19 , which can not only block fallen leaves but also filter rainwater to avoid clogging the water filter holes 27 .

[0037] The working principle of the above embodiment is as follows: the water storage tank 1 is set on the external roof. During the rainy season, rainwater can enter the interior of the protective plate 2 and be filtered through the water filter hole 27, and then be collected in the water storage tank 1. When the rainwater is saturated, it covers the outer surface of the planting box 20. The rainwater invades the water-absorbing sponge 22 and enters the interior of the planting box 20 after being guided by the water-absorbing sponge 22, thereby achieving the effect of continuously moisturizing the soil inside the planting box 20. The soil inside the planting box 20 is blocked by the water-absorbing sponge 22, which can effectively prevent soil loss. When the rainfall is heavy, the rainwater can be discharged from the drainage hole 25 to prevent the plants from being submerged. After the rainy day is over, the soil at the bottom of the planting box 20 can be continuously moisturized by the rainwater stored in the water tank 1. When the surface soil lacks moisture, the threaded rod 3 can be driven to rotate by starting the external forward and reverse motor, so that the movable plate 4 can move at a uniform speed under the limit of the guard plate 2. During the rotation of the threaded rod 3, the sprocket 24 chain is linked to drive the eccentric wheel to drive the eccentric rod 10 to move, and the piston 13 can be driven to reciprocate under the limit of the suction cylinder 14, thereby extracting the water source inside the water tank 1 and spraying it through the atomizing nozzle 6, so as to achieve a uniform irrigation effect on the plants and the surface soil.
