Description

Technical Field

[0001] The utility model belongs to the technical field of vertical greening of green buildings. Specifically, it relates to a water-saving building balcony greening planting device. Background Art

[0002] A green building refers to a building that provides healthy, comfortable and safe living, working and activity spaces for people, while achieving efficient use of resources, energy conservation, land conservation, water conservation, material conservation, and minimizing the impact on the environment. Vertical greening is one of the key technologies for the development of green buildings and an important and effective way to improve the urban ecological environment and enrich the urban greening landscape. As a main way of vertical greening, balcony greening can not only reduce the heat island effect, absorb dust and reduce noise, but also create a comfortable environment for users.

[0003] Existing building balcony greening planting facilities have certain limitations. For example, it is not convenient to collect and reuse rainwater immediately, water resources are easily wasted when watering plants, and plants are often short of water when users are away for a long time. There is an urgent need for a vertical greening planting device for water-saving reuse to solve the above drawbacks. Summary of the Invention

[0004] In order to overcome the deficiencies of the existing building balcony greening planting facilities, such as low efficiency of rainwater collection and utilization and easy waterlogging of plant roots during watering, the utility model provides a water-saving and reusable vertical greening planting device with high rainwater collection and utilization efficiency, not easy to waterlog plant roots, and high practicability.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] A water-saving and reusable vertical greening planting device includes a device body. A filtering system is arranged on one side of the top of the device body. One side of the filtering system is communicated with a water storage tank through a water delivery pipe. On the other side of the filtering system, there is a water inlet pipe for collecting rainwater, and the water inlet pipe is communicated with the upper part of the side outlet of the building downspout. On the upper part of the other side of the device body, a planting box is arranged, and a water distribution system is arranged and communicated at the lower part of the planting box. The water storage tank and the water distribution system form a communicating vessel. A drainage groove is arranged at the lower part of the device body, and a water outlet pipe is arranged at one end of the drainage groove, and the water outlet pipe is communicated with the side inlet of the building downspout.

[0007] Further, a horizontally arranged water distribution pipe is arranged inside the water distribution system, and the water distribution pipe is communicated with the bottom of the water storage tank. A sub-irrigation pipe is arranged in the vertical direction of the water distribution pipe and extends into the planting box. This scheme is a preferred scheme, and other water distribution methods can also be adopted.

[0008] Preferably, the inside of the water distribution system is filled with gravel, and the water distribution pipe is laid flat in the gravel.

[0009] More preferably, a perforated partition board is arranged at the bottom of the water distribution system and a layer of geotextile is laid; the drainage trough is located below the perforated partition board.

[0010] The interior of the planting box is filled with a planting substrate, and an upper perforated partition board is arranged at the bottom and a layer of geotextile is laid.

[0011] Furthermore, a water inlet control valve is arranged on one side of the water inlet pipe close to the device body, and a water outlet control valve is arranged on one side of the water outlet pipe close to the device body.

[0012] Preferably, a circular opening is arranged at the top of the water storage tank.

[0013] More preferably, the filtering system includes five replaceable filter columns; the five filter columns are connected in series through a water delivery pipe. Along the water flow direction, gravel substrates are filled in the five filter columns in the order of decreasing particle size from large to small. This solution is a preferred solution, and other filtering methods can also be adopted.

[0014] For the three-dimensional greening planting device for water-saving and reusing of the present utility model, the roof rainwater of a building enters the filtering system under the guidance of the water inlet pipe of the device through a downspout. A water inlet control valve is arranged on one side of the water inlet pipe close to the device body. After the rainwater is filtered step by step by the five filter columns, it flows into the water storage tank. The top of the water storage tank is closed, and only a circular opening is provided. The bottom of the water storage tank is connected to the water distribution system. The filtered rainwater is stored in the water storage tank and at the same time enters the water distribution pipe through the water outlet of the bottom of the water storage tank. The water distribution pipe is laid flat in the gravel layer of the water distribution system, and the sub-irrigation pipes are uniformly arranged at a certain interval in the vertical direction and penetrate into the upper planting box. The bottom of the water distribution system is a perforated partition board, and a layer of geotextile is laid between the gravel layer and the partition board. A drainage trough is arranged below the water distribution system, and one end of the drainage trough is connected to the water outlet pipe. A water outlet control valve is arranged on one side of the water outlet pipe close to the device.

[0015] The beneficial effects of the present utility model are mainly manifested as follows: When in use, the rainwater is filtered by the filtering system, then stored in the water storage tank, and the filtered rainwater is used to moisten the planting substrate in the planting box in the form of sub-irrigation, so as to be absorbed by the plant roots. The present utility model reuses the rainwater, saving rainwater resources; the present utility model irrigates plants in the form of sub-irrigation, saving water resources; the present utility model is provided with a drainage trough and uses the gravel layer as a measure to filter excess water, which not only avoids the phenomenon of waterlogging of plant roots caused by excessive watering, but also avoids the blockage of the building downspout; the water storage tank provided by the present utility model allows a certain amount of water to be stored and allows external water replenishment through a faucet, greatly avoiding the problem of plant water shortage caused by water cut-off due to the user's long-term absence, and has high practicability.

Specific embodiments

[0019] The present utility model will be further described below with reference to the accompanying drawings.

[0020] Refer to Figure 1 and Figure 2 A three-dimensional greening planting device for water-saving reuse includes a device body 1. A filtration system 2 is provided on one side of the top of the device body 1. A water storage tank 3 is provided on one side of the filtration system 2, and a water inlet pipe 7 is provided on the other side. A planting box 4 is provided on the upper part of the other side of the device body 1, and a water distribution system 5 is provided below the planting box 4 and they are interconnected. The water storage tank 3 and the water distribution system 5 form a communicating vessel. A drainage trough 6 is provided at the lower part of the device body 1, and a water outlet pipe 8 is provided at one end of the drainage trough 6.

[0021] In this embodiment, the inside of the filtration system 2 is five replaceable filter columns 9, and the five filter columns 9 are connected in series through a water delivery pipe; one end of the filtration system 2 is connected to the water inlet pipe 7, and the other end is connected to the water storage tank 3 through a water delivery pipe.

[0022] Specifically, when it rains, the rainwater on the roof forms runoff and drains into the building downspout. The water inlet pipe 7 intercepts part of the rainwater and enters the filtration system 2. The rainwater passes through the five filter columns in sequence, and after being filtered step by step by the filter columns, it is collected into the water storage tank 3 through the water delivery pipe, thus completing the instant filtration and storage of rainwater, which is beneficial to saving rainwater resources.

[0023] In this embodiment, the top of the water storage tank 3 is closed, provided with a circular opening 6, and the bottom is connected to the water distribution system 5.

[0024] Specifically, the closed water storage tank 3 is beneficial to protecting the filtered clean rainwater. The circular opening at the top enables users to conveniently observe the water level of the stored rainwater and also provides convenience for users to replenish water by themselves.

[0025] In this embodiment, the water distribution system 5 is filled with gravel and is provided with a water distribution pipe 10. A perforated partition 12 is set at the bottom and a layer of geotextile is laid. The water distribution pipe 10 is laid flat in the gravel, and an infiltration pipe 11 is provided in its vertical direction and extends into the planting box 4.

[0026] Specifically, since the water storage tank 3 and the water distribution system 5 form a communicating vessel, the clean rainwater stored in the water storage tank 3 will automatically flow into the infiltration pipe 11 deep in the planting box 4 through the water distribution pipe 10. The rainwater flows into the planting matrix in the planting box 4 in the form of infiltration, and moistens the surrounding soil under the capillary action of the matrix, and is then absorbed by the plant roots, thereby achieving the effect of saving water resources.

[0027] In this embodiment, the planting box 4 is filled with a planting matrix, a perforated partition 13 is arranged at the bottom and a layer of geotextile is laid.

[0028] Specifically, when the water content in the planting box 4 is high, excess rainwater will penetrate into the lower gravel layer through the perforated partition 13. The perforated partition 13 provides a bearing function for the planting matrix in the planting box 4, and the geotextile prevents soil erosion.

[0029] In this embodiment, a water inlet control valve 14 is provided on the side of the water inlet pipe 7 close to the device body 1 , and a water outlet control valve 15 is provided on the side of the water outlet pipe 8 close to the device body 1 .

[0030] Specifically, the water inlet control valve 14 and the water outlet control valve 15 provide a variety of usage scenarios for the device. When there is abundant rainfall, the water inlet control valve 14 and the water outlet control valve 15 are opened respectively. After filtration and reuse, the rainwater penetrates into the drainage trough 6 at the bottom of the device, and is guided by the outlet pipe 8 to flow into the building downpipe through the water outlet control valve 15. When there is insufficient rain, the water outlet control valve 15 is opened, and the user can directly water the planting box without worrying about root rot caused by excessive watering. Moreover, due to the presence of the drainage trough 6, excess water will not seep out of the device and pollute the balcony of the building. When the user is away for a long time, the water inlet control valve 14 and the water outlet control valve 15 are closed respectively, and the circular opening 16 set on the top of the water storage tank is used to fill it with water. The accumulated water will be slowly discharged into the planting box 4 through the water distribution system. Since infiltration irrigation is a more water-saving irrigation measure, the water accumulated in the water storage tank 3 can be used for irrigation for a longer time, and the cultivated plants will not wither due to water outage within a certain period of time.

[0031] The solution of this embodiment is applicable to a variety of usage scenarios, taking the following three scenarios as examples:

[0032] When there is abundant rainfall: Open the control valves of the inlet pipe and the outlet pipe respectively. The rainwater is filtered by five filter columns and stored in the water storage tank. At the same time, through the water distribution pipe of the water distribution system, (since the water storage tank and the water distribution pipe form a communicating vessel, there is no need for an additional water pump) the rainwater is slowly discharged into the planting box in the form of infiltration irrigation. The rainwater will moisten the soil from bottom to top under the action of soil capillary. The excess rainwater will infiltrate into the drainage trough through the gravel layer of the water distribution system (with a layer of geotextile laid on each of the upper and lower layers to prevent soil loss), and flow back into the downpipe of the building through the outlet pipe.

[0033] When there is insufficient rainwater: Open the control valve of the outlet pipe and directly irrigate the planting box. This operation will not cause waterlogging of the plants because the excess water is discharged into the downpipe through the drainage trough. Due to the filtration of the gravel layer in the water distribution system, the discharged water will not block the building downpipe; and due to the existence of the drainage trough, the excess water will not seep out of the device and pollute the building balcony.

[0034] When the user is away for a long time: Close the control valves of the inlet pipe and the outlet pipe respectively. Use the faucet to fill the water storage tank through the circular opening provided at the top of the water storage tank. The stored water will be slowly discharged into the planting box through the water distribution system, so that the plants in the planting box can grow normally; in addition, since infiltration irrigation is a relatively water-saving irrigation measure, the water stored in the water storage tank can be used for irrigation for a longer time and will not wither the cultivated plants due to water cut-off within a certain period of time.

[0035] The content described in the embodiments of this specification is only a list of the implementation forms of the utility model concept and is only for illustrative purposes. The protection scope of the present utility model should not be regarded as limited to the specific forms stated in this embodiment. The protection scope of the present utility model also extends to equivalent technical means that can be conceived by those of ordinary skill in the art based on the utility model concept.
