Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses a roof garden. Referring to fig. 1 and 2, a roof garden includes a planting box 1 provided on a roof of a building, a planting substrate 2 provided inside the planting box 1, a water supply tank 3 provided at a bottom of the planting box 1, and a water supply mechanism 4 provided inside the water supply tank 3 to supply water to the planting substrate 2. Plant case 1 and be located the roof of building, when raining, plant case 1 and collect the rainwater, and the rainwater of a part is planted matrix 2 storage, and a part rainwater flows downwards under the effect of gravity, stores in the bottom infiltration flow that plants case 1 at last enters into feed water tank 3, and when the moisture content in planting matrix 2 was less, water supply mechanism 4 can go to planting matrix 2 with the water absorption of storage in the feed water tank 3, carries out the moisturizing to the plant.

Referring to fig. 1, an opening and closing door 33 is opened at a side surface of the water supply tank 3, a sealing tape is bonded to a periphery of the opening and closing door 33, and an observation window 35 is provided on the opening and closing door 33. The worker can observe the inside of the water supply tank 3 through the observation window 35, and regularly sterilize and clean the inside of the water supply tank 3.

Referring to fig. 1 and 2, a support net 12 is welded to the bottom of the planting box 1, a drainage plate 11 is laid above the support net 12, and a planting base 2 is laid on the top of the drainage plate 11. The supporting net 12 comprises a supporting rod 121 which is crossed horizontally and vertically, and the supporting rod 121 comprises a steel rod 122 for bearing the weight of the drainage plate 11, the planting substrate 2 and the plants and a waterproof pipe 123 wrapped outside the steel rod 122. The waterproof pipe 123 is a plastic pipe made of polyvinyl chloride and has good waterproof performance. The drainage plate 11 is a plate made of volcanic rock and has good water permeability.

When the moisture content in planting matrix 2 is too much, the moisture in planting matrix 2 can flow downwards under the effect of gravity, and when unnecessary water shunted to drain bar 11, moisture can continue downward infiltration through drain bar 11, later fell into and store in water supply tank 3. In the process, the waterproof pipe 123 isolates the steel rod 122 from moisture, and the oxidation speed of the steel rod 122 is delayed. The drainage plate 11 only allows moisture to pass through, the planting matrix 2 particles with larger diameters are blocked, and the drainage plate 11 prevents the planting matrix 2 particles from blocking the supporting net 12, so that the water seepage effect is ensured.

Referring to fig. 2, the drain plate 11 is provided with a plurality of through holes, the water supply mechanism 4 is provided inside the planting substrate 2 and inside the water supply tank 3, and the water supply mechanism 4 supplies water to the planting substrate 2 through the through holes of the drain plate 11. The water supply mechanism 4 includes an irrigation line net 41 embedded inside the planting substrate 2 and a water supply line 42 connected to the irrigation line net 41. Irrigation line net 41 and water supply line 42 are made by the cotton thread that absorbs water, and irrigation line net 41 is equipped with a plurality ofly, and the uniform level is buried underground at the inside different height of planting matrix 2, and water supply line 42 is vertical to be set up, and water supply line 42 all is connected with every irrigation line net 41, and the bottom at the feed water tank 3 is placed to water supply line 42's bottom.

The water inside the water supply tank 3 is drawn into the water supply line 42 due to the capillary phenomenon, and is gradually drawn into the irrigation line net 41, and finally, into the planting substrate 2. When the moisture content in the planting base 2 reaches a certain degree, the capillary phenomenon stops.

Referring to fig. 2, an exhaust pipe 32 is further inserted into the sidewall of the water supply tank 3, the outer sidewall of the exhaust pipe 32 is welded to the sidewall of the water supply tank 3, a water replenishing pipe 31 is provided inside the sidewall of the planting tank 1, the bottom end of the water replenishing pipe 31 extends into the water supply tank 3, the top end of the water replenishing pipe 31 is connected to the water supply system of the building, and a switch valve 36 is provided on the water replenishing pipe 31.

When the worker observes that the stored water inside the water service box 3 is small through the observation window 35, the on-off valve 36 may be opened to replenish the water service box 3 using the water supply system of the building. As the water level inside the water service box 3 rises, the air inside the water service box 3 is gradually discharged from the air discharge pipe 32.

The implementation principle of a roof garden in the embodiment of the application is as follows: when raining, planting case 1 collects partly rainwater, and planting matrix 2 of planting case 1 inside stores partly rainwater, and another part rainwater flows to storing in feed water tank 3 under the effect of gravity. Meanwhile, the moisture content in the planting substrate 2 can be ensured not to be very high, the plants can be ensured to breathe normally, and the plants can grow normally. When the water content in the planting substrate 2 is low, the water supply mechanism 4 sends the water in the water supply tank 3 to the planting substrate 2, and when the water content in the water supply tank 3 is low, the worker opens the on-off valve 36 to replenish the water supply tank 3.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
