Description

Technical Field

[0001] The present invention belongs to the technical field of garden soil and water conservation, and more specifically, relates to a riverside garden rainwater and sewage recycling and tree maintenance system and method. Background Art

[0002] my country's urban water resources are extremely scarce, with an annual water shortage of about 6 billion m 3 , the economic loss caused by water shortage is about 200 billion yuan every year. The serious water shortage problem directly affects the process of urban modernization construction, GDP growth and the improvement of residents' living standards in my country. Improving the recycling of natural rainwater is an important way to improve the shortage of urban water resources. After rainwater falls on the ground, about 10% constitutes surface runoff, about 40% is consumed by road evaporation and filling, and about 50% is stored in the groundwater level and soil air-filling zone through infiltration, or replenishes groundwater through gravity. In urbanized areas, due to the influence of buildings and ground linings, the impermeable area increases, that is, "urban surface hardening", which cuts off the channel for water infiltration and groundwater replenishment, resulting in increased surface runoff, reduced soil moisture content and underground recharge. Due to the lack of water replenishment and excessive groundwater excavation, the ground subsides, making the climate in urban areas monotonous when there is no precipitation, and the ground is flooded during heavy rains, affecting traffic and residents' lives. There is abundant rainfall in southern my country. During the flood season and the plum rain season, during the construction and use of landscaping projects, if the rainwater on site is not promptly drained or recycled, it will have a significant impact on soil loss on site. At the same time, the survival rate of seedlings will be greatly reduced due to excessive water, causing root rot and waterlogging, making it difficult for seedlings to survive in large numbers.

[0003] In order to solve the above problems, patent document CN105863018A discloses a rainwater collection and utilization system, including a rainwater well, a diversion well, a discarded well, a PP module reservoir, a water purification system, a clean water tank, a variable frequency water supply device, and an ultraviolet disinfector, characterized in that: the rainwater well is divided into 1# rainwater well and 2# rainwater well, wherein: 1# rainwater well is respectively connected to the diversion well and 2# rainwater well, the diversion well is respectively connected to the PP module reservoir and the discarded well, the 1# rainwater well determines the discarded flow thickness to be 4mm, the discarded rainwater is discharged to the 2# rainwater well, and the water to be used is discharged to the diversion well, the diversion well is installed with a sewage interception device, the diversion well is respectively connected to the discarded well and the PP module reservoir, the PP module reservoir is connected to the water purification system, and the water purification system is connected to the clean water tank. However, it cannot be applied to the garden environment, and can achieve the maintenance of trees and cannot actively drain water.

[0004] In addition, patent document CN111285503A discloses using a rooftop rainwater pipe to collect rainwater on the roof, and after the initial rainwater is diverted by a flow abandonment device, it enters the rainwater tank, thus realizing the collection of rainwater on the roof; ground rainwater is collected to the rainwater wetland through permeable concrete pavement, permeable driving surface, rainwater wetland and green land, thus realizing the collection of ground rainwater; after the rainwater is collected, it is intercepted, filtered and infiltrated through the grooved volcanic rock retention pool of the rainwater wetland, and enters the sedimentation tank through a perforated collection pipe for sedimentation, thus realizing further purification treatment; after being treated in the sedimentation tank, it enters the PP water storage module box through a diversion pipe for storage, and is lifted by a clean water pump and a sewage pump, thus realizing the separation of clean water and sewage, and the sewage is discharged through the sewage pump, and the clean water is further purified through the water supply pipe through the purification integrated machine, without the need to add rainwater purifiers for purification, thus realizing the recycling of rainwater, saving water, energy and environmental protection. However, it is impossible to automatically control and adjust the water storage volume. Summary of the invention

[0049] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0050] like Figure 1 and Figure 8 As shown, an embodiment of the present invention provides a road rainwater recycling tree maintenance system, and the rainwater recycling system includes a rainwater and sewage collection and storage structure. The main implementation is to collect rainwater and sewage through the road pavement and the road rainwater grate through the rainwater pipe to collect rainwater and sewage into the rainwater and sewage collection pipe, and preliminarily treat the rainwater and sewage through the diversion well, the interception well, and the abandoned flow well, and separate the large garbage and branches and leaves from the water flow and discharge them through the sewage pipe. The rainwater and sewage that have been initially treated are collected and stored in the PP module after sedimentation treatment in the PP module sedimentation tank. Specifically, it includes a rainwater and sewage collection pipe 1, a diversion well 2, a sewage interception well 3, a abandoned flow well 4, a PP rainwater module 7, a pump 5 and a sewage pipe 6. The rainwater in the field is collected and treated by the rainwater recycling system, and the initial rainwater and sewage are separated and discharged through the diversion well 2, the interception well 3, and the abandoned flow well 4. In addition, the initial rainwater is reprocessed by the PP rainwater module 7, and the sedimentation treatment is carried out and the treated rainwater is stored. The present invention is used in a gardening environment. The temperature and humidity monitoring system is used to determine the maintenance status of trees in the field, thereby mobilizing the water stored in the pp module to perform watering and maintenance of the trees, ensuring the planting conditions of the trees and improving the survival rate of the trees. At the same time, in the storage process, the system can also monitor the water volume to ensure the rationality of the water storage volume in order to prevent the backflow of rainwater due to excessive water volume. The system of the present invention collects and aggregates rainwater through a rainwater recycling system structure, and realizes preliminary recycling of rainwater through diversion wells, sewage interception wells, and abandoned flow wells, thereby solving the problem of water accumulation in roads and parks due to excessive rainwater, thereby avoiding water accumulation on park roads that hinders traffic and ensuring the normal use of construction and the park in the later stage.

[0051] like Figure 1 and Figure 4-Figure 7As shown, the system includes a temperature and humidity monitoring 8 and a spray curing 9 and a drainage 10 system structure. The temperature and humidity monitor 8 includes a U-shaped tube 803, a water inlet pipe 801 and a drainage pipe 802 connected to the U-shaped tube 803; a motor 805 arranged on one side of the U-shaped tube 803; and a trigger 804 arranged on the side wall of the U-shaped tube 803. The trigger 804 includes a suspended ball 804A, a straight tube 804B, and an electrode 804C arranged in sequence from the bottom to the top; and a suspended rod 804D arranged inside the straight tube 804B. The main implementation is to change the up and down floating of the water level in the U-tube 803 of the monitoring instrument through the change of temperature and humidity on site, driving the position change of the suspension rod 804D and the suspension ball 804A. When the water level drops due to the influence of temperature and humidity, it means that the precipitation in the park is less at this stage and the maintenance conditions are not met, so that the suspension ball drives the suspension rod to drop synchronously, and the lower motor on the suspension rod will contact the lower electrode 804C of the U-tube to trigger the motor 805 of the monitor to start, and automatically start the spray maintenance device to water the trees in the park for maintenance; similarly, when the water level rises due to the influence of temperature and humidity, it means that the moisture maintenance in the park has reached the tree maintenance standard. When the water volume in the park is greater than the maintenance standard, the suspension ball and the suspension rod rise, and the upper electrode of the suspension rod contacts the electrode of the U-tube, triggering the motor to open the drainage system, and using the pump to discharge the stored water through the drainage pipe to prevent the stored water from flowing back due to excessive water in the PP rainwater module 7, increasing the moisture content in the soil, and causing the trees to be soaked and killed. The system of the present invention recycles and stores rainwater and sewage through the connection and drive of the rainwater recovery and discharge system and the discharge system, avoids water accumulation in the park, solves the problem of tree root death due to waterlogging caused by excessive precipitation or water accumulation in the park, and greatly improves the planting survival rate of the trees.

[0052] The tree maintenance system includes the U-shaped tube 803 in the temperature and humidity monitor, the suspension rod 804D, the suspension ball 804A, the suspension rod electrode 804C, the water inlet pipe 801, the drainage pipe 802 and the motor 805. In addition, the tree maintenance system is interconnected with the sprinkler system and the drainage system. The sprinkler system and the drainage system are braked by the tree maintenance system, so as to realize the implementation of watering and drainage. Figure 1 The temperature and humidity monitoring and drainage are shown in the attached Figure 4 , 5 The system of the present invention solves the problem of daily automatic maintenance of trees and drying up due to lack of water in the summer when precipitation is low, reduces the manpower required for park maintenance, and improves the survival rate of tree planting through the temperature and humidity monitoring system and the temperature and humidity monitoring and automatic watering maintenance functions of the spray maintenance system.

[0053] according to Figure 2 , 3As shown, the PP rainwater module 7 includes a covering layer 701 arranged at the top, a medium sand protection layer 702 arranged at the bottom of the covering layer 701, a multi-layer XPS extruded protection plate 703 arranged at the bottom of the medium sand protection layer 702, an anti-seepage wrapping material 704 arranged between the XPS extruded protection plates 703, a PP module 705 arranged at the bottom of the XPS extruded protection plates 703, a reinforced concrete bottom plate 706 and a plain concrete cushion layer 707 arranged at the bottom of the PP module 705, and a water tank docking interface 708 connected to the sewage interception well 3. Arrange the laying of PP rainwater modules 7 and roads. After the excavation is completed, first pour the plain concrete cushion layer 707, and build the reinforced concrete base plate 706 on the cushion layer. When the base plate reaches the bearing requirement, install the PP module on the base plate. After the installation is completed as required, lay two cloths and one membrane on the upper layer of the PP module to prevent the stored water from flowing back upwards. Then, set the XPS extruded protection plate 703 and the medium sand protection layer 702 layer by layer on the upper part, and finally backfill 701 with soil.

[0054] In addition, in one embodiment of the present invention, the Internet of Things (IoT) technology is deeply integrated with the road rainwater recycling tree maintenance system, and an intelligent control unit is also included to realize the automatic management and precise control of the system. The unit consists of multiple core modules, including an environmental monitoring module, a data acquisition and transmission module, a central control unit, an intelligent decision algorithm, an execution control module, and a remote monitoring interface. Through the coordination of these modules, the system can monitor and manage various environmental parameters in the park in real time, thereby ensuring the healthy growth of trees and optimizing the utilization efficiency of rainwater resources. The environmental monitoring module is the perception layer of the system, which is responsible for real-time acquisition of environmental data in the park. The module integrates a variety of sensors, including air temperature and humidity sensors, soil moisture sensors, water level sensors, and rainfall sensors. These sensors can continuously monitor temperature and humidity changes in the air, record the moisture content in the soil, monitor the water level in the PP module, and accurately measure rainfall. These data provide a basis for the decision-making of the system, ensuring that irrigation and drainage operations can be dynamically adjusted according to actual conditions. The data acquisition and transmission module adopts low-power wide area network (LPWAN) technology, through which the data of the sensor node can cover a wide range of the park under the premise of low power consumption, and ensure the stability and reliability of data transmission. Once the data is collected, it will be transmitted to the central control unit in real time via a wireless network. The application of LPWAN technology enables the system to deploy multiple sensor nodes over a large area to achieve comprehensive monitoring of the entire park without worrying about excessive energy consumption or unstable data transmission. The central control unit is the core of the entire system, and it has built-in advanced edge computing technology and intelligent decision-making algorithms. Edge computing technology enables the central control unit to perform preliminary processing and analysis before data is transmitted to the cloud, thereby reducing the system's response time and ensuring that the system can respond immediately in the event of an abnormality or emergency. The intelligent decision-making algorithm dynamically adjusts the system's operating strategy through machine learning and big data analysis technology. For example, when the system detects that the soil moisture in the park is too low, the central control unit will automatically start the spray maintenance system to ensure that the trees get enough water; and when the water level in the PP module exceeds the set safety threshold, the system will start the drainage device to drain the excess water to avoid the problem of waterlogging of the tree roots or waterlogging in the soil due to excessive water. With the support of intelligent decision-making algorithms, the system can adapt to various climatic conditions, provide precise irrigation and drainage services, and ensure the healthy growth of trees in different seasons. The executive control module is responsible for converting the instructions of the central control unit into specific operations. Through the motor controller, valve controller and other devices, the executive control module can accurately adjust the water flow and pressure to ensure that each irrigation or drainage operation meets the actual needs of the tree. The precise control capability of the executive control module not only ensures that the growth environment of the tree can meet the optimal conditions, but also prevents the waste of water resources caused by improper operation.In order to further improve the operational convenience and management efficiency of the system, the present invention also integrates a remote monitoring interface, so that managers can access the operating status of the system anytime and anywhere through smart phones, tablet computers or computers. The remote monitoring interface realizes real-time synchronization and remote control functions of data through connection with the cloud platform. Managers can not only view the current environmental data and operating status of the system, but also manually adjust system parameters, or perform remote emergency operations in case of emergency. In addition, the remote monitoring interface also supports the visualization of data. Through charts, reports and other forms, managers can intuitively understand the historical operation and trend analysis of the system, so as to make more scientific decisions. Through this function, managers can fully control the maintenance status of the trees in the entire park without visiting the site in person, greatly improving the efficiency and flexibility of management. The intelligent control system integration of the present invention significantly improves the operating efficiency and response speed of the road rainwater recycling tree maintenance system, especially in parks with complex and changeable environmental conditions, its application advantages are particularly prominent. Through the application of Internet of Things technology, the system can automatically adjust the irrigation frequency and drainage intensity according to real-time environmental data, ensure the healthy growth of trees in different seasons and climatic conditions, and avoid the adverse effects of excessive or insufficient water on trees. At the same time, the system's automated management and remote monitoring functions reduce the necessity of manual intervention, lower management costs and maintenance expenses, and are particularly suitable for centralized management of large parks. Compared with traditional manual operating systems, the intelligent control unit of the present invention is not only more efficient and accurate, but also can provide more comprehensive management and maintenance solutions through remote monitoring and data analysis, providing strong technical support for park managers. Through this innovative design, the present invention not only optimizes the utilization efficiency of water resources and improves the survival rate of tree planting, but also effectively reduces labor costs and management pressure, and has broad application prospects and market value.

[0055] like Fig. 9As shown, in another embodiment of the present invention, a construction method of a road rainwater recycling tree maintenance system is provided. First, natural precipitation and surface runoff are effectively collected through road pavement and rainwater grates, merged into underground rainwater pipes, and finally concentrated into the rainwater collection pipe 1. In the rainwater collection pipe, the rainwater is first directed to the diversion well 2 for preliminary solid-liquid separation treatment. The diversion well is designed not only to filter out larger solid impurities, such as branches, leaves and plastic bags, but also to initially alleviate the impact of the water flow, and avoid pipe blockage or reduced separation efficiency caused by too fast water flow. After preliminary treatment in the diversion well, the water flow continues to enter the sewage interception well 3, where the system further performs fine solid-liquid separation on rainwater and sewage to separate smaller solid particles and suspended matter. This dual separation mechanism effectively improves the water quality of subsequent treatment links and ensures that the water flow entering the abandoned flow well 4 has a lower pollutant content. The abandoned flow well 4 plays a vital role in the system, especially in the treatment of initial rainwater. Initial rainwater usually contains a high concentration of pollutants, which mainly come from sediments on the road, particulate matter in automobile exhaust, and pollutants generated by other human activities. The waste well automatically identifies the initial rainwater through the float control system and separates it from the subsequent cleaner rainwater. After the initial rainwater passes through the float control system, it is filtered through a special filtering device. The filtered sewage and solid waste are lifted to the sewage pipe 6 through the pump 5 for centralized discharge. This design can not only effectively treat pollutants in the initial rainwater, but also prevent pollutants from affecting the water quality in the subsequent storage and utilization links, ensuring that the water entering the PP rainwater module 7 is cleaner.

[0056] As the rainfall increases, the float system in the waste well will automatically adjust the state of the sewage pipe. When the rainfall reaches a certain level, the sewage pipe will automatically close, so that the rainwater that has been preliminarily treated can smoothly flow into the PP rainwater module 7 through the outlet for sedimentation and collection. The PP rainwater module adopts a multi-layer sedimentation and filtration design, which can further remove suspended particles and tiny impurities in the water and store the purified water in the module. The PP rainwater module not only plays the role of water storage, but also ensures that the water quality of the stored water meets the requirements of park greening maintenance through sedimentation and filtration functions. In order to prevent the problem of rainwater backflow caused by excessive water, the system is also equipped with a temperature and humidity monitoring system and a drainage system. Through automatic monitoring and adjustment, it ensures that the rainwater recycling system can still operate normally under high water conditions. After completing the initial treatment and storage of rainwater and sewage, the system monitors the environmental conditions in the park in real time through the temperature and humidity monitor 8. The core component of the temperature and humidity monitor is the U-tube 803, and the change of the water level in it can directly reflect the humidity and precipitation of the environment. When the water level in the U-shaped tube 803 is monitored to drop, it indicates that the current precipitation in the park is small and the air humidity is insufficient to meet the normal growth needs of the trees. At this time, the drop in the water level in the U-shaped tube drives the suspended ball 804A to drop synchronously, and the drop of the ball will drive the suspension rod 804D in the straight tube 804B to move downward. When the suspension rod drops to a certain extent, the lower electrode 804C on the suspension rod will contact the electrode at the bottom of the U-shaped tube, triggering the motor 805 to start. After the motor is started, the spray maintenance device 9 is automatically turned on, and the trees in the park are watered and maintained through the spray system. During the watering process, the spray system will automatically adjust the water volume and spraying range according to the actual humidity demand to ensure that each tree can obtain an appropriate amount of water.

[0057] On the other hand, when the rainfall increases or the air humidity reaches saturation, the water level in the U-shaped tube 803 will rise accordingly. As the water level rises, the suspended balls and the suspension rods will also rise synchronously. When the suspension rod rises to a certain height, the electrode on the upper part of the suspension rod will contact the electrode on the upper part of the U-shaped tube, triggering the motor to start the drainage system. At this time, the pump will automatically start and discharge the excess water stored in the PP module through the drainage pipe 10 to prevent water backflow caused by excessive water storage. The discharged water can be directed into a nearby river or a dedicated drainage system to avoid water accumulation in the park, thereby protecting the roots of the trees from the effects of excessive water.

[0058] The entire construction method combines rainwater recycling, rainwater and sewage separation, tree watering and maintenance, and drainage functions organically through scientific design and automated control, forming an efficient and intelligent ecosystem. The system not only solves the tree maintenance problem caused by excessive or insufficient rainwater in traditional park management, but also reduces the need for manual intervention through temperature and humidity monitoring and automatic adjustment mechanisms, thereby improving the efficiency of park management and the survival rate of trees. Through the present invention, park managers can better control the use of rainwater resources, while ensuring that trees can be properly maintained under various climatic conditions, greatly improving the modernization level of park greening management.

[0059] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
