Description

Technical Field

[0001] The invention relates to the technical field of urban greening, in particular to a multifunctional rainwater purification vertical greening building system. Background Art

[0002] With the acceleration of urbanization, the density of urban buildings continues to increase, the urban green area is relatively reduced, and the rational use of rainwater resources has become an urgent problem to be solved. As a way to increase the urban green area and effectively utilize rainwater resources, the vertical greening building system has received widespread attention.

[0003] Chinese patent CN105395142A discloses a rainwater greening system for the facade of a scenic area building, including a plurality of planting mechanisms equidistantly installed on a wall, a water tank placed on the ground at the lower end of the wall, a water pump fixedly installed on the side wall of the water tank, an irrigation pipeline mechanism installed on the water pump and the wall, and a water storage pipeline mechanism installed on the water tank and the wall. The invention prevents the flowers and plants in the planting trough from being flooded through drainage holes and overflow holes, reduces impurities in the water and avoids soil loss through water filter cloth, separates clean water from sediment in the water tank through sand prevention plates, avoids clogging of the water pump and the irrigation pipeline mechanism, controls drainage through two methods: a drainage button and an automatic liquid level control mechanism, increases its automation and flexibility, and has a simple structure and low cost. The inside of the water tank can be cleaned and the automatic liquid level control mechanism can be inspected by opening the box cover, and nutrient solution can be added during irrigation.

[0004] However, when the rainfall is heavy, the equipment will discharge the overflowed rainwater through the overflow holes on the planting trough for recycling to avoid damage to the plants caused by excessive rainwater. However, after a long period of rainfall, the rainwater discharged through the overflow holes will carry a certain amount of soil particles, causing a certain degree of soil loss. As time goes by and multiple rainfalls accumulate, the amount of soil in the planting trough will gradually decrease, thereby affecting the growth environment and stability of the plants. In order to maintain the normal growth of plants, manual soil replenishment is required on a regular basis, which not only increases maintenance costs and manpower investment, but also has a certain impact on the aesthetics and sustainability of the vertical greening system. In addition, soil particles mixed in the rainwater make it inconvenient to recycle rainwater.

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] See also Figures 1 to 8In an embodiment of the present invention, a multifunctional rainwater purification vertical greening building system includes a wall 1, a plurality of planting grooves 6 installed on the wall 1, and two rain shields 12 symmetrically arranged on both sides above the planting grooves 6. Sliders 8 are arranged on both sides of the rain shield 12. The slides 8 are rotatably connected to the side of the rain shield 12 close to the planting groove 6 through a connecting shaft 9. A gap is arranged between the bottom wall of the rain shield 12 and the top wall of the planting groove 6 so that the rain shield 12 can rotate with the connecting shaft 9 as the rotation center. The top wall is provided with a plurality of transmission components which respectively drive the slider 8 to move horizontally. Recovery grooves 17 are fixedly provided on both sides of the planting groove 6. An inclined baffle 19 is fixedly provided on the side of the top of the recovery groove 17 away from the planting groove 6. The top of the inclined baffle 19 contacts the bottom wall of the rain shield 12 so that the outer side of the rain shield 12 tilts upward. When used specifically, the green plants are planted in the planting groove 6. When the rainfall is small, the top of the inclined baffle 19 contacts the bottom wall of the rain shield 12 so that the outer side of the rain shield 12 tilts upward, so that rain drops fall on the bottom wall of the rain shield 12. The rain shield 12 is mounted on the rain shield 12, and flows into the planting groove 6 along the inclined surface of the rain shield 12, thereby collecting rainwater, so that the rainwater gradually flows into the planting groove 6, thereby expanding the rainwater collection area, so that the planting groove 6 can collect more rainwater when the rainfall is small, so as to facilitate the growth of green plants. When the rainfall is large, the slider 8 is driven to move by the transmission component, so that the two rain shields 12 are close to each other, thereby blocking part of the rainwater entering the planting groove 6, thereby preventing too much rainwater from entering the planting groove 6 and causing the inside of the planting groove 6 to be blocked. Rainwater overflows and causes soil loss, and when the two rain shields 12 approach each other, as the contact position between the rain shield 12 and the inclined baffle 19 gradually shifts toward the direction close to the planting groove 6, under the action of the rain shield 12's own gravity, the outer side of the rain shield 12 tilts downward, so that the rainwater dripping on the rain shield 12 gradually drips onto the inclined baffle 19, and flows along the surface of the inclined baffle 19 to the recovery trough 17 for recovery. Since this part of the rainwater does not contact the soil, it will not be mixed with soil particles, which is convenient for subsequent purification treatment.

[0022] The present invention drives the two rain shields 12 to be closer to each other when the rainfall is large, through the arrangement of the rain shield 12 and the transmission assembly, so as to limit the excessive rainwater from entering the planting trough 6 and avoid overflow and erosion of the soil. At the same time, when the outer side of the rain shield 12 is tilted downward, the rainwater that has not contacted the soil is directly diverted to the recovery trough 17, thereby blocking the mixing of rainwater and soil from the source, and significantly reducing the problem of soil particles being discharged with the overflow. Compared with traditional passive protection means such as water filter cloth 23 and sand control plate, this scheme can significantly reduce the soil loss rate, reduce the frequency of artificial soil filling and maintenance cost by actively controlling the rainwater path through long-term use; and the design of the recovery trough 17 and the inclined baffle 19 separates the uncontaminated rainwater from the overflow of the planting trough 6, avoids the mixing of rainwater into soil particles, simplifies the subsequent purification process, and at the same time, the rain shield 12 expands the water collection area when the rainfall is small, and switches to the rainwater diversion mode when the rainfall is heavy, which not only guarantees the water demand of plants, but also maximizes the amount of rainwater recovered, and significantly improves the system's dynamic adaptability to rainwater.

[0023] In this embodiment, preferably, the transmission assembly includes a guide rail 7 fixedly mounted on the top wall of the planting trough 6, a spring 10 and a traction rope 11 arranged inside the guide rail 7, four guide rails 7 are arranged, which are respectively arranged on both sides of two rain shields 12, the slider 8 is slidably mounted inside the guide rail 7, the slider 8 is elastically connected to the inner wall of the guide rail 7 through the spring 10, one end of the traction rope 11 is fixedly connected to the slider 8, and a traction assembly connected to the traction rope 11 for transmission is arranged on the planting trough 6; the traction assembly includes a guide ring 14 fixedly mounted on the planting trough 6 and a counterweight box 15 slidably arranged on the front side of the planting trough 6, the end of the traction rope 11 away from the slider 8 passes through the guide ring 14 and is fixedly connected to the counterweight box 15, and the bottom wall of the counterweight box 15 is provided with a plurality of drainage holes 1501, and the aperture of the drainage hole 1501 is 3mm-8mm, The total drainage rate of multiple drainage holes 1501 is lower than the infiltration rate of the soil in the planting trough 6. The counterweight box 15 is set to be open, and a first filter screen 16 is fixedly installed at the top opening of the counterweight box 15. The setting of the first filter screen 16 can prevent impurities from entering the counterweight box 15 and blocking the drainage holes 1501; when it rains, rainwater drips into the counterweight box 15. If the rainfall is small, the rainwater entering the counterweight box 15 is discharged through the drainage holes 1501, so that the weight of the counterweight box 15 remains unchanged, and the position of the rain shield 12 remains unchanged. When the rainfall is large, the speed at which the rainwater entering the counterweight box 15 is discharged through the drainage holes 1501 is lower than the speed at which the rainwater enters the counterweight box 15, and the weight of the counterweight box 15 gradually increases, thereby pulling the slider 8 to move through the traction rope 11, so that the two rain shields 12 are close to each other.

[0024] In the present embodiment, preferably, a roller 27 is rotatably installed on the side of the rain shield 12 away from the planting groove 6, and a gap is arranged between the roller 27 and the rain shield 12, so that when the outer side of the rain shield 12 tilts downward, the roller 27 contacts the inclined baffle 19, and rainwater on the surface of the rain shield 12 flows downward to the inclined baffle 19 through the gap between the roller 27 and the rain shield 12.

The positioning block 25 can be locked by tightening the locking bolt 26; through the setting of the positioning block 25, the sliding range of the slider 8 can be limited, so that the slider 8 can stop sliding after it moves to contact with the positioning block 25, thereby adjusting the moving range of the rain shield 12 to prevent the rain shield 12 from clamping the stems of green plants.

[0026] In this embodiment, preferably, side baffles 18 are fixedly installed on both sides of the top of the recovery trough 17, and a second filter screen 20 is fixedly installed between the two side baffles 18 and the inclined baffle 19; through the setting of the side baffles 18, the openings on both sides of the inclined baffle 19 can be closed, thereby preventing external impurities from entering the recovery trough 17, and the setting of the second filter screen 20 can play a filtering role when recycling rainwater, thereby preventing external impurities from entering the recovery trough 17 when recycling rainwater.

[0027] In this embodiment, preferably, a plurality of filter slots 5 are fixedly installed on the side wall of the wall 1, and the planting slots 6 are embedded and installed on the filter slots 5; a limiting block is fixedly provided in the middle of the inner wall of the filter slot 5, and the bottom wall of the filter slot 5 is in contact with the limiting block, thereby supporting the planting slots 6, and the planting slots 6 can be taken out from the filter slot 5 to facilitate the removal and installation of the planting slots 6.

[0028] In this embodiment, preferably, an elastic part 13 is provided on the rain shield 12, and the elastic part 13 is of detachable design. A notch 1301 is provided on the side of the elastic part 13 close to the planting groove 6; the notch 1301 is adapted to the stems of the green plants to prevent them from hitting the stems of the green plants. The notch 1301 can be provided in different shapes according to the different green plants. The elastic part 13 is made of rubber material, and even if it hits the green plants, it can adaptively deform and protect the green plants.

[0029] See also Figure 1 to Figure 3 and Fig. 9In the embodiment of the present invention, a water tank 2 is fixedly provided on one side of the bottom of the wall body 1, and a plurality of sprinkler heads 4 are provided on the wall of the wall body 1, and the sprinkler heads 4 are arranged one by one corresponding to the planting troughs 6. A protection box 3 is provided on the water tank 2, and a water pump (not shown in the figure) is provided in the protection box 3, and the sprinkler head 4 is connected with the water tank 2 through the water pump; a first water supply pipeline (not shown in the figure) is provided inside the wall, and the first water supply pipeline is connected with the sprinkler head 4 through the water pump; the water in the water tank 2 can be pumped into the first water supply pipeline through the water pump, and then sprayed out through the sprinkler head 4, so as to replenish water for the green plants on the planting troughs 6.

[0030] In this embodiment, preferably, a water filter cloth 23 is provided at the bottom of the planting trough 6, and the soil can be filtered through the water filter plate so that rainwater in the soil can seep downward. The inner cavity of the filter trough 5 is provided with a water purification component 24, and the bottom of the filter trough 5 is connected to a drain pipe 22 connected to the water storage tank 2, and the bottom end of the recovery trough 17 is connected to a connecting pipe 21, and the bottom end of the connecting pipe 21 is connected to the filter trough 5, and the water outlet end of the connecting pipe 21 is located above the water purification component 24; a second water supply pipeline (not shown in the figure) is provided inside the wall 1, and the drain pipe 22 is connected to the water storage tank 2 through the second water supply pipeline. The water purification component 24 uses a combination of quartz sand, activated carbon, non-woven fabrics, expanded clay, manganese sand and other filtering materials to filter rainwater. The rainwater entering the filter trough 5 is purified by the purification component and then enters the water storage tank 2 for collection, effectively preventing impurities from entering the water storage tank 2 and causing water pollution.

[0031] Working principle: When in use, the green plants are planted in the planting trough 6. When the rainfall is small, the top of the inclined baffle 19 contacts the bottom wall of the rain shield 12 to make the outer side of the rain shield 12 tilt upward, so that rainwater drops on the rain shield 12 and flows into the planting trough 6 along the inclined surface of the rain shield 12, thereby collecting the rainwater and making it gradually flow into the planting trough 6, thereby expanding the rainwater collection area, so that the planting trough 6 can collect more rainwater when the rainfall is small, so as to facilitate the growth of green plants. When the rainfall is large, the rainwater drops into the counterweight box 15, and the speed at which the rainwater entering the counterweight box 15 is discharged through the drainage hole 1501 is lower than the speed of the rainwater entering the counterweight box 15, thereby causing the weight of the counterweight box 15 to gradually increase. The slider 8 is pulled by the traction rope 11 to move, so that the two rain shields 12 are close to each other, thereby blocking part of the rainwater entering the planting trough 6, thereby preventing too much rainwater from entering the planting trough 6 and causing the rainwater in the planting trough 6 to overflow and cause soil loss. In addition, when the two rain shields 12 are close to each other, as the contact position of the rain shield 12 and the inclined baffle 19 gradually shifts toward the direction close to the planting trough 6, under the action of the rain shield 12's own gravity, the outer side of the rain shield 12 tilts downward, so that the rainwater dripping on the rain shield 12 gradually drips onto the inclined baffle 19, and flows along the surface of the inclined baffle 19 to the recovery tank 17, and then enters the filter tank 5 through the connecting pipe 21, and enters the water storage tank 2 for collection after purification by the purification component.
