The second baffle plate and the fifth baffle plate are formed by pressing polyurethane particles together, and there are gaps between the particles of the pressed polyurethane plate, and the gap can be passed through by a small amount of water flow to play the role of filtration.

The working principle of this vertical greening system is as follows:

The water source first enters the water collection tank. Since the water collection tank is filled with base material, the base material can filter the filtered water. At the same time, hydroponic plants can be grown in the water collection tank, and the microorganisms in the water can be decomposed by the rhizomes of the hydroponic plants. to purify. Since there is a gap between the first baffle and the bottom of the top filter box, the filtered water can flow out from the gap and flow out to the nearest third baffle. The bottom is fixed, and the filtered water is blocked by the third baffle and intercepted to form a filter space similar to the settlement area. The filter space can be filled with base materials, and hydroponic green plants can also be planted to filter the sewage again. When the water slowly pours in, the water level of the filter space rises higher and higher. When the height of the high water level exceeds the height of the third baffle, it flows to the adjacent third baffle, and so on for repeated filtration, and finally made of polyurethane material. The second baffle of the urethane board blocks, the gap between the polyurethane board particles allows the water to slowly seep into the water storage tanks 1-7, and the last filtration of the top filtration is performed;

After the top filter mechanism is filtered, it is transported to the bottom filter mechanism through the sewer pipe. At the same time, because the sewer pipe is connected with the water pipe, when the humidity in the soil is below the set value, the signal is transmitted to the controller, which is controlled by The device opens the valve and the water flows out of the infiltration pipe to irrigate the soil layer. If a water spray pipe is installed, the water spray pipe can spray water mist on the surface of the branches and leaves of the green plants. ;

The bottom of the sewer pipe can be connected to the bottom filter box through the elbow and enter the water storage tank. The water storage tank and the fourth baffle can also be filled with base material or planted with hydroponic green plants. The principle is the same as the top filter mechanism to purify Due to the staggered arrangement of the third baffle and the fourth baffle, when the position is above, a baffle net can be set between the bottom of the baffle and the bottom of the filter box to prevent the loss of base material, and it can also be placed on the bottom of the lower layer. In the choice of base material, the base material with a particle size larger than the gap is selected to solve this problem;

After being filtered by the bottom filter mechanism, it is blocked by the fifth baffle in the same way, and the seepage filter is carried out. From time to time, it is collected into the water purification area, and finally the water is sent to the top filter mechanism through the water circulation mechanism for continuous filtration.

The roof ecological greening system includes a planting mechanism, a water well mechanism and a water collecting tank. The planting mechanism is communicated with the water well mechanism and the water collecting tank. A filtering mechanism is arranged in the water collecting tank, and the filtering mechanism is a filter cotton layer and/or a filter particle layer. The water collecting tank can be hidden under the interior of the roof, which has an overall beautiful and neat effect.

The planting mechanism can be used to plant green plants, the water well mechanism is used to collect rainwater diverted from the planting mechanism, and the water collection tank has the function of storing water and sewage in a unified process and filtering treatment, which can be used for the inflow through the roof and the well mechanism. The filtered water is filtered so that the filtered water is used for irrigation of the planting establishment.

Plants and flowers are planted in the planting mechanism, and the planting mechanism is composed of several densely arranged planting units. The roof design of the public toilet is designed with a low inclination in the middle and high sides. The inclination angle can be a slope ratio of 2 degrees that cannot be observed by the naked eye. The slope can also be made larger. In short, it can be adjusted according to the design needs of the public toilet, but at least the slope ratio must be designed to prevent the roof from storing water and play a role in diverting the rainwater. There is a water collecting tank inlet on the lower edge of the roof, which can collect the rainwater falling on the roof surface into the water collecting tank, so that when the planting units are arranged, it will form a slope from the middle to the edge, and the water will pass through the slope by gravity. Angled for flow collection and collection into the well mechanism or water collection tank.

The planting mechanism includes several planting units, each planting unit includes a flowerpot 2-1, a water retention box 2-2 is arranged at the lower part of the flowerpot 2-1, a water seepage component is arranged at the bottom of the flowerpot 2-1, Planting soil is laid on the water seepage component, an installation gap 2-3 is opened at the opening of the side of the flowerpot 2-1, a first water guide strip 2-4 is arranged on the installation gap 2-3, and a water retention box 2-2 is arranged on the installation gap 2-3. A second water guiding strip 2-5 is opened at the opening of the edge.

The water seepage component includes a second polyurethane plate 2-6, a constriction is provided at the bottom of the flowerpot, and the second polyurethane plate is installed on the constriction. Green plants and flowers are planted in flowerpots. When the rain falls, the excess rainwater can flow into the water-retaining box through the second polyurethane plate 2-6 to form a water-retaining layer. The second polyurethane plate is also formed by hot pressing of polyurethane particles. There are pores between the polyurethane particles, which makes the polyurethane board water-permeable and breathable, and the capillary roots of plants can penetrate the polyurethane board and extend down into the water-retaining layer. , to prevent root rot due to lack of oxygen. Because of the sloping design of the roof, the position of the water retention box placed in the middle of the roof is relatively high. When the water seeps into the water retention box, the water can be guided to the adjacent water retention box located on the downhill through the second water guide, so that it flows in turn. , and finally converge to the edge of the roof, and then through the slope of the roof, the water is naturally introduced into the water collection tank located at the extreme edge of the roof for recycling and filtration.

In order to ensure the water level in the water storage box and provide water for plant roots, a water level sensor is installed in the highest water storage box. The water level sensor is opened through the water level controller and the control valve on the water passage. When the water level is too low, the The water level controller opens the control valve for watering, so that the water to be watered flows from the flowerpot downward through the second polyurethane plate to the water retention box. Of course, it can also connect a water pipe from the water collecting tank to a water retention box at a high position. , when the water level in the water storage box is too low, the water level controller transmits the signal to the water level controller, and then starts the control valve on the water that is too small through the water level controller to send the water in the water collection tank into the water storage box. After the inner water level is full, it flows to the water retention box located on the downhill in turn.

The water well mechanism forms a water system on the roof, which is used to collect, filter and purify the rainwater, and then send it to the water collection tank for secondary filtration.

Since the water seepage board is also made of polyurethane, the water seepage board

When the rain is too heavy and the amount of water is too late to seep into the water-retaining box below the flowerpot, a water overflow will be formed in the flowerpot. By setting the first water guide, the height of the flowerpot in the middle is higher than the position due to the influence of the slope. For flower pots that are downhill, when the rainwater forms a water flow, it will conduct water through the first water guiding strip, and the water flow will be guided into the flowerpots that are adjacent and located on the downslope, flow in turn, and finally collect to the water well box at the farthest edge. . The rainwater collected into the well box can be filtered once through the base material, and then filtered through the polyurethane board for the second time, so as to filter the impurities in the rainwater and the mud mixed in the flower pot into the water tank, and then pass through the seepage pipe. Filter again, and at the same time, because the seepage pipe is connected with the water collection tank, the filtered water will enter the water collection tank and be finely filtered through the water collection tank.

Of course, in order to further improve the filtering effect and beautifying effect, hydroponic plants can also be planted in the well box, and the microorganisms in the water can be decomposed and filtered through the root system of the plants.

It can be pumped out through the water pipe for watering, and can also be sprayed through the water spray pipe. Spray the leaves to improve air humidity and beauty.

Rooftop ecosystems work by:

When it rains, the rainwater falls into the plant surface of the flowerpot and then into the planting soil. When the water in the planting soil is saturated, it will flow into the water-retaining box under the flowerpot through the water seepage component, which is placed in the position of the water-reserving box in the middle of the roof. It is relatively the highest. Water penetrates into the water-retaining box to form a water-retaining layer. When the water level in the water-retaining box rises, the water can be guided to the adjacent water-retaining box located on the downhill through the second water guide, so that it flows in turn, and finally converges to the The edge of the roof flows into the water collection tank for recycling and filtration. When the rain is too heavy and the amount of water is too late to seep into the water-retaining box below the flowerpot, a water flow will be formed in the flowerpot. By setting the first water guide, the height of the flowerpot in the middle is slightly higher than that due to the influence of the slope ratio. For flower pots that are located downhill, when the rainwater forms a water flow, it will conduct water through the first water guide strip, and the water flow will be guided into the flowerpots that are adjacent and located on the downslope, flowing in turn, and finally to the water well box at the farthest edge. collection. The rainwater collected into the water well box can be filtered through the base material, and then filtered through the polyurethane board, and the impurities in the rainwater and the mud mixed in the flowerpot are filtered into the water tank, and then filtered and transported again through the seepage pipe. , At the same time, because the seepage pipe is connected with the water collection tank, the filtered water will enter the water collection tank and be finely filtered by the water collection tank. When the water collection tank is finely filtered to meet the watering requirements, it is drawn out through the water pipe for watering.
