Description

Technical Field

[0001] This utility model relates to the field of vertical greening, specifically a modular, quick-installation urban vertical greening planting unit. Background Technology

[0002] Urban greening is an activity that adds green space to cities through planting trees, flowers, and other plants during the planning, construction, and development process. It is an indispensable part of sustainable urban development. It can not only purify the air, regulate the climate, and reduce noise, but also beautify the urban landscape and improve the quality of life for residents. For example, plants absorb carbon dioxide and release oxygen through photosynthesis; vegetation cover can regulate the local urban climate, alleviate the heat island effect, and lower summer temperatures; trees and lawns can also absorb dust and reduce noise, creating a more livable living environment for residents.

[0003] Traditional planar greening methods are insufficient to meet the growing demand for greening in cities with limited land resources. To overcome the limitations of land resources, urban vertical greening has emerged. It makes full use of the vertical space of the city, such as building walls, roofs, balconies, and overpasses, for planting. Existing urban vertical greening technologies include climbing plant greening, modular greening, and bag greening. These technologies have increased the green area of ​​the city to a certain extent and alleviated the ecological pressure on the city.

[0004] Modular greening is assembled using prefabricated planting modules, which offers a degree of flexibility and convenience. However, it still has some shortcomings. The solidified soil planting modules cannot store water, and after receiving drip irrigation, excess water or rainwater cannot be recycled, resulting in a waste of water resources and hindering the healthy growth of plant roots. Therefore, a modular, quick-installation urban vertical greening planting unit is proposed. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a modular, quick-installation urban vertical greening planting unit to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular quick-installation urban vertical greening planting unit, including a planting unit, a drip irrigation pipeline is provided on the top of the planting unit, and multiple planting units are interconnected by a connecting structure. A water collection device is fixedly connected to the bottom of the planting unit by a buckle, and the water collection devices are interconnected by a connecting structure.

[0007] The water collection device includes a water collection chamber, a first drain outlet, and a second drain outlet. The water collection chamber is located inside the water collection device, and the first and second drain outlets are fixedly installed at both ends of the water collection device for interconnection of multiple sets of water collection devices. A sealing cap is provided at the end of the second drain outlet near the water collection chamber to seal the second drain outlet. A positioning block is fixedly installed on the side of the sealing cap adjacent to the second drain outlet, and a slider is fixedly installed on the outside of the positioning block. A limiting groove corresponding to the slider is opened on the inside of the second drain outlet.

[0008] By adopting the above technical solution, the modular installation of planting units and water collection devices can accelerate the installation process and significantly improve installation efficiency. The docking and cooperation of the first and second drainage pipes, when multiple water collection devices are spliced ​​together, the first drainage pipe squeezes the positioning block, which drives the sliding edge limit groove to slide, so that the sealing cover is separated from the inner wall of the water collection cavity, automatically forming a flow channel, realizing a sealing structure of docking pressure and automatic on / off, which can reduce the risk of water leakage without additional valves and unnecessary operations.

[0009] Furthermore, the outer diameter of the first drain pipe opening corresponds to the inner diameter of the second drain pipe opening, so as to ensure that when multiple sets of water collection devices are connected to each other, the first drain pipe opening is inserted into the second drain pipe opening for mutual communication.

[0010] By adopting the above technical solution, multiple water collection devices can be quickly spliced ​​together through pipe openings, and after connection, they can form a continuous drainage channel, perfectly adapting to the assembly requirements of modular three-dimensional greening systems. This facilitates flexible expansion of the water collection range according to the greening area, while standardized interfaces also reduce production, transportation, and maintenance costs.

[0011] Furthermore, the bottom of the limiting groove is designed to be inclined, and the end away from the water collection cavity is the lowest point, which is used to ensure that the position of the slider is restricted when the second drain pipe is in a closed state.

[0012] By adopting the above technical solution, the inclined limiting groove guides the slider, thereby ensuring the precise control of the opening and closing process of the cover and avoiding accidental displacement caused by external forces such as vibration.

[0013] Furthermore, a filter layer is fixedly installed on the top of the water collection chamber to filter impurities contained in the dripping water, and a flap is rotatably installed on one side of the water collection device for replacing the filter layer.

[0014] By adopting the above technical solution, the filter layer can directly intercept impurities such as substrate residue, fallen leaves, and plant debris carried by irrigation or rainwater dripping, preventing them from entering the water collection chamber and clogging the drain pipe and water pump, reducing the risk of system failure, and ensuring the smooth circulation of recycled water.

[0015] Furthermore, when multiple sets of the water collection devices are connected to each other, a water pump is installed in the water collection device at the end, and the water pump is connected to a water storage box through a water pipe. The water storage box is located at the top of the planting unit. A rubber plug is fixedly installed at the first drain outlet at the end of the water collection device to seal the first drain outlet, and the water pipe passes through the rubber plug.

[0016] By adopting the above technical solution, the water storage box is located at the top of the planting unit, and the height difference is used to create natural water pressure, which facilitates the recycling of water through the drip irrigation pipeline for gravity irrigation, thereby reducing additional power consumption and improving the energy efficiency of water circulation.

[0017] Furthermore, multiple sets of positioning blocks are fixedly installed on one side of the closed cover. The positioning blocks and the first drain pipe cooperate with each other to ensure that when multiple sets of water collection devices are connected to each other, the first drain pipe abuts against and pushes the positioning blocks. A sealing sheet is fixedly installed on the side of the closed cover adjacent to the second drain pipe.

[0018] By adopting the above technical solution, multiple sets of positioning blocks form multiple points of contact with the first drain pipe opening, which can evenly distribute the thrust during docking, thereby avoiding the deviation or jamming caused by excessive force on a single positioning block, and ensuring that the first drain pipe opening accurately abuts and pushes the positioning block when inserted into the second drain pipe opening.

[0019] In summary, the present invention has the following main advantages:

[0020] This invention features a water collection and recycling system. The water collection device, through its modular design, allows for rapid installation and expansion with planting units via snap-fit ​​or slots. The design of the first and second drainage ports enables the water collection device to be connected during installation. The sealing structure at the pipe ports provides pressure during connection, and the automatic on / off sealing structure reduces the risk of leakage without the need for additional valves or unnecessary operations. The water collection device eliminates the need for specialized components during production, facilitating standardized manufacturing, reducing production costs, and minimizing installation errors. By constructing a closed loop with the interconnected water collection device, pump, and storage tank, irrigation wastewater and rainwater are collected, stored, and recycled after filtration, significantly improving water resource utilization. Water savings can reach 40%-60%. Furthermore, the filter layer, after prolonged use, can be removed and cleaned or replaced by opening the flap from the outside, eliminating the need to disassemble the water collection device and reducing maintenance costs.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] Example 1

[0030] A modular, quick-installation urban vertical greening planting unit, such as Figure 1-5 As shown, it includes a planting unit 1, with a drip irrigation pipe 3 installed on the top of the planting unit 1, which allows water to be accurately dripped into the solidified soil matrix, reducing the loss due to evaporation and runoff in traditional irrigation. Multiple planting units 1 are interconnected by a connecting structure. A water collection device 2 is fixedly connected to the bottom of the planting unit 1 by a buckle, and the water collection devices 2 are interconnected by a connecting structure. By modularly installing the planting unit 1 and the water collection device 2, the installation project can be quickly advanced, thereby greatly improving the installation efficiency.

[0031] The water collection device 2 includes a water collection chamber 26, a first drain outlet 22, and a second drain outlet 23. The water collection chamber 26 is located inside the water collection device 2 and is used to temporarily store the recycled water. The first drain outlet 22 and the second drain outlet 23 are respectively fixedly installed at both ends of the water collection device 2 for interconnection of multiple sets of water collection devices 2. A sealing cap 25 is provided at the end of the second drain outlet 23 near the water collection chamber 26 to seal the second drain outlet 23. The sealing cap 25 and the second drain outlet are connected. A positioning block 252 is fixedly installed on one side of the adjacent 23, and a slider 253 is fixedly installed on the outside of the positioning block 252. A limiting groove 231 corresponding to the slider 253 is opened on the inner side of the second drain pipe 23. Through the docking and cooperation of the first drain pipe 22 and the second drain pipe 23, when multiple sets of water collection devices 2 are spliced, the first drain pipe 22 squeezes the positioning block 252, which drives the slider 253 to slide along the limiting groove 231, so that the closed cover 25 is separated from the inner wall of the water collection cavity 26, and automatically forms a flow channel.

[0032] Please see Figure 1-5 The outer diameter of the first drainage pipe opening 22 corresponds to the inner diameter of the second drainage pipe opening 23, so that the first drainage pipe opening 22 can be tightly fitted after being inserted into the second drainage pipe opening 23, thereby avoiding water seepage and leakage. When multiple sets of water collection devices 2 are connected to each other, the first drainage pipe opening 22 is inserted into the second drainage pipe opening 23 to connect them. This allows multiple sets of water collection devices 2 to be quickly spliced ​​through the pipe openings, and after connection, they can form a continuous drainage channel. This perfectly adapts to the assembly requirements of the modular three-dimensional greening system, making it easy to flexibly expand the water collection range according to the greening area. At the same time, the standardized interface also reduces the cost of production, transportation and maintenance.

[0033] Please see Figure 1-5 The bottom of the limiting groove 231 is inclined. The inclined limiting groove 231 guides the slider 253, thereby ensuring the precise control of the opening and closing process of the sealing cover 25 and avoiding accidental displacement due to external forces such as vibration. The end away from the water collection cavity 26 is the lowest point, which is used to ensure that the position of the slider 253 is restricted when the second drain pipe 23 is in the closed state. This allows the single group or end water collection device 2 to use the locking position of the slider 253 at the low position of the limiting groove 231 to make the sealing cover 25 fit tightly and achieve a seal, without the need for additional manual operation of the valve, thus simplifying the installation process.

[0034] Please see Figure 1-5A filter layer 21 is fixedly installed on the top of the water collection chamber 26 to filter impurities contained in the dripping water. The filter layer 21 can directly intercept substrate residue, fallen leaves, plant debris and other impurities carried by irrigation or rainwater dripping, preventing them from entering the water collection chamber 26 and clogging the drain pipe and water pump 27, reducing the risk of system failure and ensuring the smooth circulation of recycled water. A flap 24 is rotatably installed on one side of the water collection device 2 for replacing the filter layer 21. The flap 24 can be opened from the outside, so that the filter layer 21 can be replaced without disassembling the entire water collection device 2. The operation is simple and quick, greatly reducing the difficulty of maintenance and labor costs.

[0035] Please see Figure 1-5 When multiple water collection devices 2 are interconnected, a water pump 27 is installed in the end water collection device 2 to extract the collected recycled water at close range, shortening the water pumping path. The water pump 27 is connected to a water storage box 28 through a water pipe, and the water storage box 28 is located at the top of the planting unit 1. The water storage box 28 is located at the top of the planting unit 1, and the height difference creates natural water pressure, which facilitates the recycling water to flow through the drip irrigation pipe 3 for gravity irrigation, thereby reducing additional power consumption and improving the energy efficiency of water circulation. A rubber plug 221 is fixedly installed on the first drain pipe 22 at the end of the water collection device 2 to seal the first drain pipe 22. By sealing the first drain pipe 22 of the end water collection device 2 with the rubber plug 221, water leakage when the module is not connected is blocked, and a passage is provided for the water pipe of the water pump 27 to pass through. The water pipe passes through the rubber plug 221, and the elasticity of the rubber plug 221 can tightly fit the pipe opening and the outer wall of the water pipe.

[0036] Please see Figure 1-5 Multiple sets of positioning blocks 252 are fixedly installed on one side of the closed cover 25. Through multiple sets of positioning blocks 252 forming multiple points of contact with the first drain pipe 22, the thrust during docking can be evenly distributed, thereby avoiding the displacement or jamming caused by excessive force on a single positioning block 252. This ensures that when the first drain pipe 22 is inserted into the second drain pipe 23, it accurately abuts against and pushes the positioning block 252. The positioning block 252 and the first drain pipe 22 cooperate with each other to ensure that when multiple sets of water collection devices 2 are connected to each other, the first drain pipe 22 abuts against and pushes the positioning block 252. A sealing plate 251 is fixedly installed on the side of the closed cover 25 adjacent to the second drain pipe 23. The setting of the sealing plate 251 can effectively prevent water leakage in the unconnected state, thereby ensuring the sealing of the water collection device 2 when used independently or at the end.

[0037] The working principle of this utility model is as follows: the planting unit 1 and the water collection device 2 are both independent modules. When the water collection device 2 is installed, the first drain pipe 22 of one set of water collection devices 2 is connected to the second drain pipe 23 of another set. When the first drain pipe 22 is inserted into the second drain pipe 23, the end face of the first drain pipe 22 is attached to the end of the positioning block 252 inside the second drain pipe 23 and pressure is applied to it, so that the positioning block 252 drives the slider 253 to slide towards the closing cover 25. When the two sets of water collection devices 2 are installed, the first drain pipe 22 is also smoothly inserted into the second drain pipe 23 and fits tightly. At the same time, the slider 253 slides to the higher end of the limiting groove 231, and the positioning block 252 undergoes a slight deformation, which makes it easy for the closing cover 25 to return to the closed state later. At this time, the closing cover 25 and the inner wall of the water collection cavity 26 are not in contact, and the two sets of water collection devices 2 are in a state of mutual communication, which facilitates the flow of subsequent recycled water.

[0038] After multiple sets of water collection devices 2 are installed, the second drain pipe 23 of the last set of water collection devices 2 is in a closed state, the slider 253 is located at the lower end of the limiting groove 231, to prevent the slider 253 from sliding out due to external vibration or other accidental sliding, and the sealing plate 251 is tightly attached to the inner wall of the water collection cavity 26 to enhance the sealing performance.

[0039] The planting unit 1 module has a solidified soil matrix layer inside that is suitable for plant growth. It can provide plants with good water retention, air permeability and nutrients. The modules can be quickly assembled together by means of fasteners or slots and fixed on the installation surface. Then, the plants are placed in the planting cup, the soil is filled and compacted.

[0040] During the later maintenance process, the solidified soil and plants are irrigated through the drip irrigation pipe 3 at the top. During irrigation or rainfall, excess water gradually seeps from the upper planting unit 1 and drips into the water collection device 2 at the bottom for temporary storage. When the water enters the water collection device 2, it will first pass through the filter layer 21 for initial filtration to intercept substrate residue, fallen leaves, etc. When the amount of water recovered in the interconnected water collection chamber 26 reaches the height of the pipe opening, the recovered water will flow through the first drain pipe 22 and the second drain pipe 23 to the water collection device 2 at the beginning. The water pump 27 installed in the water collection device 2 at the beginning pumps the recovered water into the water storage box 28 for storage and standby. The water storage box 28 is interconnected with the drip irrigation pipe 3. When the substrate is short of water, the recovered water in the water storage box 28 can be used for drip irrigation first, which greatly improves the water resource utilization rate.

[0041] After long-term use, the filter layer 21 can be opened to remove the filter layer 21 for cleaning or replacement without removing the water collection device 2, which facilitates later maintenance.
