Description

Technical Field

[0001] This invention relates to the field of irrigation technology, and in particular to a water-saving and emission-reducing fully automatic drip irrigation system. Background Technology

[0002] Water is the source of life. Many large and medium-sized cities in my country are water-scarce or water-poor cities, with a long-term shortage of high-quality freshwater resources. At the same time, these cities generally have high levels of urban greening and road cleaning. To maintain greening and road cleanliness, a large amount of tap water is consumed every year for green space irrigation and road washing, resulting in significant pressure on urban water use.

[0003] For most large and medium-sized cities along my country's southeast coast, the average annual rainfall is about 1200 mm. Nationwide, natural rainfall has always been a freshwater resource with great development and utilization value. However, under the current construction model, rainwater generated by a large number of hardened underlying surfaces such as building roofs and elevated bridge decks is mostly discharged directly into rivers, lakes, or near-shore areas through rainwater pipe networks, failing to realize the utilization of rainwater resources.

[0004] This traditional drainage method not only directly wastes water resources but also increases energy consumption for rainwater transport and end-of-pipe discharge. Meanwhile, some residential and public green spaces, especially those under elevated roads, suffer from severe natural rainfall insufficiency due to obstruction by upper structures, resulting in significantly higher drought stress levels than conventional green spaces. To compensate for the lack of natural rainfall, significant manpower and resources must be invested in artificial irrigation, further exacerbating the dual pressures of water consumption and maintenance costs. In addition, urban road washing, building exterior wall washing, construction sites, and certain businesses also consume large amounts of freshwater resources.

[0005] Therefore, in order to overcome the above-mentioned shortcomings, there is an urgent need in this field for a water-saving drip irrigation technology to achieve energy-saving and efficient rainwater collection and urban greening irrigation. Summary of the Invention

[0006] The following provides a brief overview of one or more aspects to offer a basic understanding of them.

Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed descriptions that follow.

[0007] To overcome the above-mentioned defects, the present invention provides a water-saving and emission-reducing fully automatic drip irrigation system, which can achieve energy-saving and efficient rainwater collection and provide urban greening irrigation and water supply services by setting water storage containers under buildings and roads.

[0008] Specifically, a first aspect of the present invention provides a water-saving and emission-reducing fully automatic drip irrigation system, comprising a first water storage container, a first inlet pipe, a first outlet pipe, and at least one drip irrigation pipe.

Thus, during summer rainstorms, this invention can utilize multiple water storage containers to store large amounts of natural rainfall, thereby mitigating urban flooding and waterlogging problems to some extent.

[0013] Furthermore, in some embodiments of the present invention, the upper part of the first water storage container is also provided with an overflow port, wherein the height of the overflow port is greater than the second liquid level, and is connected to a waste liquid discharge pipe.

[0015] Furthermore, in some embodiments of the present invention, the above-mentioned water-saving and emission-reducing fully automatic drip irrigation system further includes a second water outlet pipe. The first end of the second water outlet pipe is connected to the first water outlet, and the second end leads to the ground for supplying water to road washing vehicles and / or greening irrigation vehicles.

[0016] Furthermore, in some embodiments of the present invention, the first water storage container is also provided with a removable insulation layer, wherein the insulation layer is located on the outer side of the outer wall, the inner side of the inner wall, and / or between the outer wall and the inner wall of the first water storage container.

[0017] Furthermore, in some embodiments of the present invention, the water-saving and emission-reducing fully automatic drip irrigation system also includes a communication interface and a third switch. The communication interface is used to connect a humidity sensor, a remote controller, and / or a weather forecast data center to acquire soil moisture signals, remote control signals, and / or weather signals, wherein the humidity sensor is buried in the soil of the green area. The third switch connects the first water outlet pipe and the communication interface, and is used to open or close the first water outlet pipe based on the soil moisture signals, remote control signals, and / or weather signals provided by the communication interface.

[0018] Furthermore, in some embodiments of the present invention, the water-saving and emission-reducing fully automatic drip irrigation system further includes at least one camera and an image analysis module. The at least one camera is used to capture photos of the greenery. The image analysis module is used to analyze the photos to determine the growth status of the greenery, wherein the growth status is selected from one of normal, water-deficient, or fertilizer-deficient conditions.

[0029] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Although the description of the present invention is presented in conjunction with preferred embodiments, this does not mean that the features of the invention are limited to these embodiments. On the contrary, the purpose of describing the invention in conjunction with embodiments is to cover other options or modifications that may be derived based on the claims of the present invention. To provide a thorough understanding of the invention, many specific details will be included in the following description. The invention may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of the invention, some specific details will be omitted in the description.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] Furthermore, the terms "upper," "lower," "left," "right," "top," "bottom," "horizontal," and "vertical" used in the following description should be understood as the orientations shown in the relevant paragraphs and accompanying drawings. These relative terms are for illustrative purposes only and do not imply that the described apparatus must be manufactured or operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0032] It is understood that although terms such as "first," "second," and "third" may be used herein to describe various components, regions, layers, and / or parts, these components, regions, layers, and / or parts should not be limited by these terms, and these terms are only used to distinguish different components, regions, layers, and / or parts. Therefore, the first components, regions, layers, and / or parts discussed below may be referred to as second components, regions, layers, and / or parts without departing from some embodiments of the present invention.

[0033] As mentioned above, many large and medium-sized cities in my country are water-scarce cities due to water quality issues, and the supply of high-quality freshwater resources has been tight for a long time. At the same time, these cities generally have a high level of urban greening and road cleaning. In order to maintain greening and road cleanliness, a large amount of tap water is consumed every year for green space irrigation and road washing, resulting in significant pressure on urban water use.

[0034] my country's freshwater resources account for only 6% of the world's total, yet they support nearly 20% of the global population. Per capita freshwater resources are only one-quarter of the world average, necessitating trillions of yuan in investment for water management and coordination. Therefore, fully utilizing natural rainfall to achieve greening and carbon reduction is urgently needed.

[0035] However, hundreds of millions of cubic meters of natural rainfall are directly discharged into rivers in my country every year. For most large and medium-sized cities along my country's southeast coast, the average annual rainfall is about 1200 mm, and natural rainfall itself is a freshwater resource with great development and utilization value. Taking Shanghai as an example, if we estimate the total roof area of ​​buildings in Shanghai at 150 square kilometers and the average annual rainfall at 1200 mm, we can see that under ideal conditions, the amount of natural rainfall received and discharged by building roofs in Shanghai each year is approximately [amount missing]. Cubic meters, or 180 million tons of rainwater. Meanwhile, please refer to... Figures 1-4 , Figures 1-4 This diagram illustrates existing urban greening irrigation methods and their growth effects. For most large and medium-sized cities in southeastern coastal my country, such as... Figures 1-4 As shown, most urban landscaping requires regular watering and maintenance. If watering is not timely, the plants will... Figure 4 As shown, the plants are withered and lying on the ground. Taking Shanghai as an example, according to the "Shanghai Citizen Price Information Guide," the price of water for greening in Shanghai is 4-6 yuan / ton. Calculating at an average of 5 yuan / ton, if only 90% of the aforementioned 180 million tons of natural rainfall were used for irrigating greenery, approximately [amount missing] yuan / ton could be saved annually. Yuan. Expanding the statistical area to the entire country would yield an astonishing number year after year.

[0036] However, under the current construction model, rainwater generated by a large number of artificially hardened surfaces such as building roofs and elevated bridge decks is mostly discharged directly into rivers, lakes, or near-shore areas through rainwater pipe networks, failing to realize the utilization of rainwater resources. Moreover, for urban roads, rainwater drainage has certain costs, including labor and equipment costs. The total cost of rainwater drainage is called the drainage fee. Taking Shanghai as an example, the drainage fee for one ton of rainwater is about 1 yuan, that is, the drainage fee for the aforementioned 180 million tons of natural precipitation is about 180 million yuan. And the drainage fee is even more staggering nationwide.

[0037] Therefore, for the portion of freshwater resources from natural rainfall, traditional drainage methods not only directly waste water resources but also increase energy consumption for rainwater transport and end-of-pipe discharge, resulting in a significant economic burden. Furthermore, some residential and public green spaces, especially those under elevated roads, suffer from severe drought stress due to insufficient natural rainfall replenishment caused by overhead structures. To compensate for the lack of natural rainfall, a large amount of manpower and resources must be invested in artificial irrigation, further exacerbating the dual pressure of water consumption and maintenance costs. In China, the total green area in urban built-up areas is approximately 27.058 billion square meters. For each square meter of green space, the annual water consumption for irrigation is approximately 1 ton. Assuming a cost of 5 yuan per ton for manpower, equipment, and water, the annual cost of irrigating public green spaces alone reaches 135.29 billion yuan.

[0038] Therefore, to overcome the above-mentioned shortcomings, this invention provides a water-saving and emission-reducing fully automatic drip irrigation system. By installing water storage containers beneath buildings, structures, and / or elevated roads, it achieves energy-efficient and high-performance rainwater collection for urban greening irrigation. Ideally, this invention can store over 90% of natural rainfall from rooftops in the storage containers, and then automatically irrigate urban green spaces and rural fields, or use it for washing roads, construction sites, and industrial water supply, reducing the discharge of natural rainfall resources by over 90%. This significantly improves the carbon reduction and aesthetic effects of urban greening, and conserves agricultural water.

[0039] Specifically, please refer to Figures 5-9 , Figure 5 The diagram illustrates a fully automated drip irrigation system for water conservation and emission reduction according to some embodiments of the present invention. Figure 6 The diagram shows a partial control architecture of a fully automated drip irrigation system for water saving and emission reduction, according to some embodiments of the present invention. Figures 7-9 A schematic diagram illustrating the installation location of a first water storage container according to some embodiments of the present invention is shown.

[0040] like Figure 5 As shown, the water-saving and emission-reducing fully automatic drip irrigation system of the present invention includes a first water storage container 1, a first water inlet pipe 2, a first water outlet pipe 3, and at least one drip irrigation pipe 4.

[0041] like Figures 7-9 As shown, the first water storage container 1 is located below residential buildings, structures (referring to man-made building entities that do not have human habitation functions and are mainly used for specific engineering purposes) and / or elevated roads, wherein, Figures 5-7The white boxes in the diagram mark the areas where the water storage containers are placed. These areas include, but are not limited to, elevated roads, bridges, elevated highways, and ordinary urban roads. Thus, the water storage container 1 is connected to artificial hard surfaces such as rooftops and elevated roads via drainage pipes, thereby storing large amounts of rainwater during rainy days.

[0042] In some non-limiting embodiments, the water storage container 1 can be made of plastic and set as a large plastic barrel with a height of 2 to 3 meters and a bottom diameter of 2 meters. The top view of the container includes various shapes such as circle, square, rectangle, and ellipse.

[0043] For further information regarding the appearance of the aforementioned water storage container 1, please refer to [link / reference needed]. Figures 10A-10F , Figures 10A-10F A schematic diagram of the appearance of a water storage container according to some embodiments of the present invention is shown.

[0044] like Figures 10A-10F As shown, in some non-limiting embodiments, the water storage container is designed to blend into the urban landscape. The appearance of the water storage container should integrate with the building; it can be a wall shape, a column shape, or it can be incorporated into the urban landscape, for example, in… Figure 10A The exterior of the water storage container can be a rockery as shown, or for example, in... Figure 10B The exterior of the water storage container can be that of the plant shown, or for example, in... Figure 10C The exterior of the water storage container can be a column as shown, or for example, in... Figure 10D The exterior of the water storage container can be the wall of the building shown, or for example, in... Figure 10E The exterior of the water storage container can be a fence-like wall, as shown, or for example in... Figure 10F The exterior of the water storage container can be the wall of the community shown.

[0045] In some embodiments, the water storage container is provided with a first inlet and a first outlet. The first inlet is located in the upper part of the first water storage container (including the top surface, the junction of the top surface and the side surface, and the upper half of the side surface), and the first outlet is located in the lower part of the first water storage container (including the bottom surface, the junction of the bottom surface and the side surface, and the lower half of the side surface). External drain pipes are installed on both sides of the lower part of the plastic water container for connecting to drip irrigation pipes. One end of the first inlet pipe is connected to the rainwater drainage pipe of the building, structure, and / or elevated road, and the other end is connected to the first inlet.

[0046] In some embodiments, the first water outlet pipe 3 is disposed on both sides of the lower part of the plastic water container, and external drain pipes are respectively installed thereon for connecting to the drip irrigation pipe. One end of the first water outlet pipe is connected to at least one first water outlet, and the other end is connected to at least one drip irrigation pipe 4.

[0047] In some embodiments of the present invention, several or more drip irrigation pipes are installed on both sides of the outside of the external drainage pipe according to actual needs. In order to reduce water evaporation and extend the service life of the plastic drip irrigation pipes, the drip irrigation pipes 4 are buried in the green soil below the first water storage container according to actual needs, so as to realize drip irrigation without the need for a water pump by utilizing the gravity of water. Specifically, the drip irrigation pipes 4 are buried in the soil at a depth of about 5 to 10 centimeters, and the spacing between each drip irrigation pipe is about 50 to 80 centimeters.

[0048] Please refer to Figure 5 Furthermore, in some embodiments of the present invention, the water-saving and emission-reducing fully automatic drip irrigation system further includes a second inlet pipe (not shown in the figure), a liquid level detection mechanism (not shown in the figure), and a first switch (not shown in the figure). The first end of the second inlet pipe is connected to a supplementary water source (e.g., a municipal tap water pipe), and the second end is connected to the first inlet. Please refer to further details. Figure 6 In some embodiments of the control architecture of this invention, a water inlet hose switch 10 is provided at the first end of the second water inlet pipe connected to the supplementary water source. This water inlet hose switch 10 is used to control the supplementary water source. The liquid level detection mechanism is located inside the first water storage container and is used to measure the actual liquid level in the first water storage container. The liquid level detection mechanism includes, but is not limited to, an electronic level gauge and a buoyancy ball valve. The first switch connects the second water inlet pipe and the liquid level detection mechanism. The first switch opens when the actual liquid level in the first water storage container is lower than a preset first liquid level to open the second water inlet pipe, and closes when the actual liquid level in the first water storage container is higher than the first liquid level to shut off the second water inlet pipe.

[0049] Thus, the water-saving and emission-reducing fully automatic drip irrigation system installed through the second water inlet pipe can replenish water sources and maintain stable drip irrigation for the green areas.

[0050] Please refer to the following. Figure 11 , Figure 11 A schematic diagram of a second water storage container according to some embodiments of the present invention is shown.

[0051] Furthermore, in some embodiments of the present invention, the water-saving and emission-reducing fully automatic drip irrigation system further includes at least one second water storage container and a second switch 5. The second water storage container is located below a building, structure, and / or elevated road, and is configured as a large cylindrical tank with a height of 8 to 15 meters and a bottom diameter of 6 to 8 meters. In some embodiments, the second water storage containers may be arranged side by side on the side of the first water storage container. The second water storage container is provided with a second water inlet and a second water outlet, wherein the second water inlet is located in the upper part of the corresponding second water storage container (including the top surface, the junction of the top surface and the side surface, and the upper half of the side surface), and is connected to the first water inlet pipe via the second switch, and the second water outlet is located in the lower part of the corresponding second water storage container (including the bottom surface, the junction of the bottom surface and the side surface, and the lower half of the side surface), and is connected to the first water outlet pipe. The second switch is connected to the liquid level detection mechanism. The second switch opens when the actual liquid level in the first water storage container is higher than the preset second liquid level, so as to open the second water inlet of the corresponding second water storage container. It closes when the actual liquid level in the first water storage container is lower than the second liquid level, so as to shut off the second water inlet of the corresponding second water storage container. It should be noted that the second liquid level is higher than the first liquid level.

[0052] Thus, the present invention enables the expansion of the drip irrigation pipe when there is an excess of rainwater and the reduction of the pipe when there is a shortage of rainwater, thereby increasing the liquid level to pressurize the drip irrigation pipe and reducing the evaporation of stored water, so as to store as much rainwater as possible.

[0053] Please continue to refer to Figure 5 Furthermore, in some embodiments of the present invention, the upper part of the first water storage container is also provided with an overflow port 6, wherein the height of the overflow port is greater than the second liquid level, and is connected to a waste liquid discharge pipe 7 (e.g., municipal rainwater discharge pipe, municipal sewage discharge pipe).

[0054] Furthermore, in some embodiments of the present invention, the first water storage container is supported by a base, and the bottom surface of the first water storage container is provided with a sloping structure and a third outlet. The third outlet is located at the lowest point of the sloping structure, lower than the first outlet, and is connected to a waste liquid discharge pipe 7 (e.g., a municipal sewage discharge pipe). Please refer to... Figure 6 In some embodiments of the control architecture, the third outlet is controlled by a remote-controlled drain switch 12. In some embodiments, the bottom surface of the first water storage container may also be configured as a cone protruding downward at an inclined angle, with the third outlet located at the lowest point of the cone, so that impurities such as mud and sand can be fully settled and discharged through the third outlet.

[0055] Thus, by setting up a sloping structure and a third outlet for drainage, the present invention can avoid silt clogging the drip irrigation pipe.

[0056] Please refer to the following. Figure 12 , Figure 12A schematic diagram of the ground end of the second water outlet pipe is shown, according to some embodiments of the present invention.

[0057] Furthermore, in some embodiments of the present invention, the water-saving and emission-reducing fully automatic drip irrigation system further includes a second water outlet pipe. The first end of the second water outlet pipe is connected to the first water outlet, and the second end extends to the ground and is connected to a water supply switch. This is used to supply water to vehicles and / or rainwater pipes, and can also be used for vehicle washing, construction sites, and other places where water is needed. Figure 12 As shown, the second end of the second water outlet pipe can be connected to the road surface water supply device. In use, the water pipe is connected to this device. Figure 12 The water supply device shown can supply water to vehicles and / or rainwater pipes, wherein the rainwater pipes can be connected to sewer pipes or water supply devices, etc. In some embodiments, the above-mentioned water supply device can also be installed near construction sites or squares for supplying water to clean construction sites and wash square floors. In other embodiments, please continue to refer to... Figure 6 In the control architecture, the second end of the second water outlet pipe can also be connected to the car wash water supply switch 11 to use rainwater to wash the vehicle.

[0058] Furthermore, in some embodiments of the present invention, the water storage container is also provided with a removable insulation layer, wherein the insulation layer is located on the outer side of the outer wall of the water storage container.

[0059] Please continue to refer to this. Figure 6 , Figure 6 A partial control architecture diagram of a fully automated drip irrigation system for water conservation and emission reduction, according to some embodiments of the present invention, is shown.

[0060] Furthermore, in some embodiments of the present invention, the water-saving and emission-reducing fully automatic drip irrigation system further includes a communication interface and a third switch. The communication interface is used to connect to a humidity sensor 8, a remote controller, and / or a weather forecast data center to acquire soil moisture signals, remote control signals, and / or weather signals, and accordingly control the humidity sensor control switch 9. The humidity sensor 8 includes multiple hygrometers buried in the soil of the green area, and these hygrometers are used to detect the actual soil moisture. The third switch connects the first water outlet pipe and the communication interface, and is used to open or close the first water outlet pipe according to the soil moisture signal, remote control signal, and / or weather signal provided by the communication interface. Specifically, the third switch opens when the actual soil moisture is less than a preset humidity threshold to open the first water outlet pipe, and closes when the actual soil moisture is greater than the humidity threshold to shut off the first water outlet pipe. In some embodiments, the water-saving and emission-reducing fully automatic drip irrigation system further includes a water pump installed on the first water outlet pipe to fully pump rainwater collected in a water storage container to the drip irrigation pipe for green area drip irrigation.

[0061] Furthermore, in some embodiments of the present invention, each hygrometer is distributed in pairs in the soil of the greening area, and one is selected for activation. Specifically, under normal working conditions, only one automatic humidity sensor is activated, while the other is used as a backup.

[0062] Furthermore, in some embodiments of the present invention, the water-saving and emission-reducing fully automatic drip irrigation system further includes at least one camera and an image analysis module. The at least one camera is used to take photos of the greenery. The image analysis module is used to analyze the photos to determine the growth status of the greenery, wherein the growth status is selected from one of normal, water-deficient, fertilizer-deficient, or diseased conditions. Specifically, the cameras primarily serve a monitoring function, with two cameras installed at regular intervals to monitor the plant growth.

[0063] It should be noted that the specific algorithms and steps for analyzing greenery photos to determine its growth status do not involve any technical improvements to this invention. Those skilled in the art can consult relevant prior art to determine the specific steps, which will not be elaborated upon here.

[0064] Furthermore, in some embodiments of the present invention, the first water storage container is also provided with a feeding mechanism for feeding materials (e.g., fertilizers, plant medicines) that are adapted to the growth conditions of greening.

[0065] In some embodiments, the feeding mechanism includes a feeding port located on the top or side of the first water storage container for dispensing fertilizer adapted to the growth conditions of the greenery.

[0066] Furthermore, in some embodiments, the feeding mechanism also includes multiple storage units for storing various fertilizers and a robotic arm.
