Description

Technical Field

[0001] This invention belongs to the field of ecological restoration technology, specifically relating to a distributed purification system and method for the restoration of sandy ecological environment. Background Technology

[0002] Due to their poor soil, lack of water, and sparse vegetation, sandy land ecosystems are highly susceptible to land degradation and desertification, severely impacting ecological balance and human life and production. In the field of sandy land restoration, traditional methods often rely heavily on extensive human intervention and physical measures, such as afforestation and the establishment of protective forest belts. While these methods can improve the sandy environment to some extent, they suffer from high costs, slow results, and difficulty in maintaining long-term sustainability. Particularly in sandy environments with unstable rainfall, the lack of effective real-time monitoring and response mechanisms significantly hinders restoration effectiveness. Most existing sandy land restoration systems fail to fully utilize rainfall resources and lack the ability to dynamically adjust restoration measures based on rainfall levels. Furthermore, the treatment of rainwater and sand mixtures generated during rainfall often lacks efficient separation and utilization methods. This not only wastes valuable rainwater resources but may also exacerbate soil erosion in sandy areas, causing further damage to the ecological environment. Summary of the Invention

[0003] The purpose of this invention is to provide a distributed purification system and method for the restoration of sandy ecological environments, in order to solve the problems mentioned in the background art.

[0004] The present invention achieves the above objectives through the following technical solutions:

[0005] Firstly, the present invention provides a distributed purification system for the restoration of sandy ecological environment, including at least one purification terminal and at least one monitoring terminal connected to its signal;

[0006] The monitoring terminal is used to monitor the real-time rainfall in the area where the corresponding purification terminal is located, and to transmit the real-time rainfall to the purification terminal.

[0007] The purification terminal is used to match the real-time operating logic according to the real-time rainfall and to purify the water and soil in its area.

[0008] The purification terminal includes a box installed on the sandy slope, a bladder-like component at the bottom of the box and adapted to the sandy slope, a collection chamber 1 for collecting water and a collection chamber 2 for collecting sand and gravel located inside the box, at least two hollow prongs on the side of the box and a dispensing component connected thereto, and a sand discharge component connected to the collection chamber 2. When the real-time rainfall exceeds a set value, the dispensing component is activated to dispense the ecological restoration agent into the sandy area through the hollow prongs, and the sand discharge component is activated to discharge the sand and gravel collected on the sandy slope into the sandy area.

[0009] Furthermore, the dispensing component is used to dispense one or more of probiotic agents, biochemical agents, and environmental modifiers into the sand through the hollow prongs, and the dispensing component includes a quantitative dispenser.

[0010] Furthermore, the sand discharge assembly includes a straight pipe, a bend, a sand collection chamber, and a blow-suction pump and a sand discharge port connected to the second collection chamber.

[0011] Furthermore, the upper surface of the box is provided with a recessed portion, and a plurality of collection holes are evenly provided on the recessed portion. Two symmetrically arranged arc-shaped guide plates are provided in the space below the recessed portion. The collection holes and the arc-shaped guide plates form two flow channels with gradually narrowing diameters. The ends of the flow channels are connected to the upper opening of the second collection chamber. The first collection chamber is cylindrical and is located inside the second collection chamber. A set gap is provided between the first collection chamber and the upper opening of the second collection chamber for large particles of sand and gravel to pass through.

[0012] Furthermore, a separation assembly is provided at one end of the collection chamber facing the flow channel. The separation assembly includes an upper disc and a lower disc that are rotatably connected by a rotating shaft. A coil spring is sleeved on the rotating shaft, and the end connection point of the coil spring is fixedly connected to the lower disc.

[0013] The rotating shaft is located at the center of the upper and lower discs, and a through hole is opened longitudinally on the rotating shaft for water to flow through. Several flow holes are provided on the upper disc along a circular path with the same center. Several arc-shaped blades are provided on the upper end face of the upper disc facing the lower end of the flow channel. The water and sand flowing down into the flow channel drive the arc-shaped blades to rotate, causing the upper disc to rotate intermittently relative to the lower disc, so that the flow holes two on the upper disc and the flow holes four on the lower disc are intermittently aligned.

[0014] Furthermore, the side of the box is provided with a foot pedal for fixing the hollow plug, and the side of the hollow plug is provided with several drain ports.

[0015] Furthermore, the box is equipped with a liquid injection pipe for connecting the dispensing component and the hollow plug. The first collection chamber is connected to the liquid injection pipe through a branch pipe, and the second collection chamber is connected to the straight pipe through a branch pipe. The branch pipe consists of two horizontal sections and a bent section. The second collection chamber is connected to the liquid injection pipe through the bent section. An electric heating component is provided in the upper horizontal section.

[0016] Secondly, the present invention provides a distributed purification method for the restoration of sandy land ecosystems, implemented based on any one of the distributed purification systems described above, the method comprising:

[0017] S1. Monitor the real-time rainfall in the area where the corresponding purification terminal is located through the monitoring terminal, and transmit the real-time rainfall to the purification terminal.

[0018] S2. The purification terminal matches the real-time operation logic according to the real-time rainfall. When the real-time rainfall exceeds the set value, the delivery component is activated to deliver the ecological restoration agent to the sandy land through the hollow plug.

[0019] S3. Activate the sand discharge component to discharge the sand and gravel collected on the sandy slope to the sandy area.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. This invention monitors rainfall in real time through a monitoring terminal and transmits the data to a purification terminal, enabling the system to dynamically adjust its operating logic based on rainfall. When rainfall exceeds a set value, the system automatically activates the delivery component, delivering probiotic agents, biochemical agents, or environmental modifiers to the sandy land through hollow plugs to promote the improvement of soil structure and vegetation growth.

[0022] 2. The design of the sand-discharging component in this invention enables the system to effectively collect and discharge sand and gravel from sandy slopes while retaining and utilizing rainwater resources. This not only alleviates soil erosion in sandy areas but also improves water resource utilization efficiency. The design of the collection chamber and separation component enables multi-stage separation and purification of the rainwater-sand mixture, improving treatment efficiency and effectiveness. In particular, the separation component, through the design of a rotating disk, achieves intermittent alignment of the flow holes, further improving separation accuracy.

[0023] 3. The system of this invention adopts a modular design, which facilitates maintenance and upgrades. Simultaneously, multiple purification terminals and monitoring terminals can form a distributed network to achieve synchronous monitoring and restoration of large-area sandy ecological environments.

Detailed Implementation

[0031] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0032] Example 1

[0033] like Figure 1-6As shown, this embodiment proposes a distributed purification system for the restoration of sandy land ecosystems, including at least one purification terminal 1 and at least one monitoring terminal 2 connected to it via a signal. The monitoring terminal 2 is used to monitor the real-time rainfall in the area where the corresponding purification terminal 1 is located, and to transmit the real-time rainfall to the purification terminal 1. The purification terminal 1 is used to match the real-time operating logic according to the real-time rainfall and to purify the soil and water in its area. The purification terminal 1 includes a box set on the sandy slope, a bladder-like component 13 located at the bottom of the box and adapted to the sandy slope, a collection chamber 102 for collecting water and a collection chamber 104 for collecting sand and gravel located inside the box, at least two hollow plugs 12 located on the side of the box and a delivery component 16 connected thereto, and a sand discharge component 15 connected to the collection chamber 104. When the real-time rainfall exceeds a set value, the delivery component 16 is activated to deliver the ecological restoration agent to the sandy land through the hollow plugs 12 to promote the improvement of the sandy soil structure and the growth of vegetation. The sand discharge component 15 is activated to discharge the sand and gravel collected on the sandy slope to the sandy area.

[0034] More preferably, the dispensing component 16 is used to dispense one or more of probiotic agents, biochemical agents, and environmental modifiers into the sand through the hollow plug 12, and the dispensing component 16 includes a quantitative dispenser.

[0035] More preferably, the sand discharge assembly 15 includes a straight pipe 151, a bend 152, a sand collection chamber 153 connected to the collection chamber 2 104, and a blow-suction pump 154 ​​and a sand discharge port 155 provided on the sand collection chamber 153.

[0036] In a further preferred embodiment, the upper end face of the box is provided with a recessed portion 14, and a plurality of collection holes 141 are evenly provided on the recessed portion 14 (for collecting rainwater and sand and gravel from sandy slopes). Two symmetrically arranged arc-shaped guide plates 101 are provided in the space below the recessed portion 14. The lower part of the collection holes 141 and the arc-shaped guide plates 101 form two flow channels 103 with gradually narrowing diameters (the arrangement of the arc-shaped guide plates 101 and the flow channels 103 causes rainwater and sand and gravel to form a downward flow). The end of the flow channel 103 is connected to the upper opening of the second collection chamber 104. The first collection chamber 102 is cylindrical and is located inside the second collection chamber 104. A set gap is provided between the first collection chamber 102 and the upper opening of the second collection chamber 104 for large particles of sand and gravel to pass through. A separation assembly 105 (for separating large particles of sand and gravel from rainwater) is provided at the end of the collection chamber 102 facing the flow channel 103. The separation assembly 105 includes an upper disc 1051 and a lower disc 1055 rotatably connected by a rotating shaft 1058. A coil spring is sleeved on the rotating shaft 1058, and the end connection point of the coil spring is fixedly connected to the lower disc 1055. The rotating shaft 1058 is located at the center of the upper disc 1051 and the lower disc 1055, and the rotating shaft 1058 has a through hole in the longitudinal direction for water to flow through. The upper disc 1051 has... A number of flow holes 1053 are provided on the circular path with the same center. A number of arc-shaped blades 1054 are provided on the upper end face of the upper disk 1051 facing the lower end of the flow channel 103 (for rotating under the water flow rushing down in the flow channel 103). The water and sand rushing down in the flow channel 103 drive the arc-shaped blades 1054 to rotate, causing the upper disk 1051 to rotate intermittently relative to the lower disk 1055, so that the flow holes 1053 on the upper disk 1051 and the flow holes 1057 on the lower disk 1055 are intermittently aligned.

[0037] Combination Figure 4 In this embodiment, the rotating shaft 1058 is located at the center of the upper disc 1051 and the lower disc 1055. The upper end of the rotating shaft 1058 is fixed at the center of the upper disc 1051 by setting a flow hole 1052, and a flow hole 3 1056 is opened at the center of the lower disc 1055 for rotatably connecting with the lower end of the rotating shaft 1058. The wall of the flow hole 3 1056 is fixedly connected to the end connection point of the coil spring, so that the upper disc 1051 and the lower disc 1055 rotate intermittently relative to each other under the impact of the water flow and sand mixture.

[0038] It should be noted that the sand and gravel collected by the collection hole 141 on the recess 14 in this embodiment mainly comes from sand and gravel blown by the wind near the sandy slope.

[0039] Understandably, the design of the collection chamber and separation component 105 in this embodiment enables multi-stage separation and purification of the rainwater and sand mixture, improving treatment efficiency and effectiveness. In particular, the separation component, through the design of a rotating disk, achieves intermittent alignment of the flow holes (flow hole two 1053 and flow hole four 1057), further improving separation accuracy.

[0040] Combination Figure 5 In a further preferred embodiment, the side of the box is provided with a foot pedal 11 for fixing the hollow plug 12, and the side of the hollow plug 12 is provided with several drainage ports 121. When the monitoring terminal is deployed, the box is deployed as a whole on the sandy slope by means of the foot pedal 11, and the hollow plug 12 is inserted into the slope soil to achieve overall fixation. The drainage ports 121 are used to supply the separated rainwater for subsequent irrigation or to mix with ecological restoration agents for restoration.

[0041] Combination Figure 2 and Figure 3 Further preferably, the box body is provided with an injection pipe 106 for connecting the dispensing component 16 and the hollow plug 12. The first collection chamber 102 is connected to the injection pipe 106 through a branch pipe 107, and the second collection chamber 104 is connected to the straight pipe 151 through a branch pipe 108. The branch pipe 108 consists of two horizontal sections and a bend section. The two horizontal sections are arranged vertically inside the box body. The second collection chamber 104 is connected to the injection pipe 106 through the bend section (specifically through a branch pipe 109 connected to the bend section). Pipe 106 is connected, and a filter screen is installed inside the injection pipe 106 to prevent sand and gravel from entering the injection pipe 106. An electric heating component (or an electric heating plate, which can be used to dry the sand and gravel in the upper horizontal section) is installed in the upper horizontal section. In specific implementation, large sand and gravel particles and rainwater collected in the collection chamber 102 enter the first horizontal section of the branch pipe 2 108. Rainwater enters the injection pipe 106 through the branch pipe 3 109. The sand and gravel enter the upper horizontal section after passing through the bend section. After being dried, they enter the dispensing component 16.

[0042] During implementation, when monitoring terminal 2 detects rainfall exceeding a set value, the control unit in monitoring terminal 2 sends a command to purification terminal 1 to activate the collection chamber and collect the mixture of rainwater and sand. Subsequently, the sand discharge component 15 begins operation, discharging the sand and gravel out of the system. Simultaneously, the separation component 105 activates, achieving efficient separation of rainwater and sand and gravel through the rotation of the rotating disc and the intermittent alignment of the flow orifices. The separated rainwater enters the storage and utilization system for subsequent use. Meanwhile, if environmental parameters meet the application conditions, the control unit sends a command to the ecological restoration agent application component 16, which applies the ecological restoration agent to the sandy land through the hollow pin 12.

[0043] In this embodiment, monitoring terminal 2 is deployed in different areas of the sandy land, using a high-precision rain gauge to monitor rainfall in real time, and transmitting the data to purification terminal 1 wirelessly or via wired means. Monitoring terminal 2 also has environmental parameter monitoring functions (such as temperature, humidity, soil moisture, etc.) to provide more comprehensive environmental data support. Purification terminal 1 includes collection chambers (collection chamber one 102 and collection chamber two 104), a sand discharge assembly 15, a separation assembly 105, and a rainwater storage and utilization system. The collection chambers are responsible for receiving the mixture of rainwater and sand, the sand discharge assembly 15 discharges the sand, and the separation assembly 105 uses a rotating disk and other mechanisms to achieve efficient separation of rainwater and sand. The separated rainwater enters the storage and utilization system for subsequent irrigation or ecological restoration.
