[0002] The hinterland of the "Ji Zi Bay" of the Yellow River is short of water resources and unevenly distributed in time and space. It is a structural and engineering water-deficient area. Therefore, the water resource utilization rate in the "Ji Zi Bay" area of ​​the Yellow River has become a key issue that needs to be solved urgently. As a relatively common soil and water conservation project in the Loess Plateau, the silt dam system not only plays the role of intercepting sediment, maintaining water and soil, and preventing floods and ensuring harvest, but also brings new challenges to hydrological cycles, efficient use of water resources, and surrounding ecological governance. If these problems can be solved in time, the silt dam in the "Ji Zi Bay" area of ​​the Yellow River will be more global, economical, and ecological. Among them, the efficient use of water resources is the most urgent problem to be solved. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0063] like Figures 1 to 7 As shown, one aspect of the present application provides a silt dam system, comprising a silt dam 02, a bank gate 11, a silt accumulation area gate 18 and a buffer zone gate 13, all of which are used to be set between two adjacent watershed mountains 01. The bank gate 11, the silt accumulation area gate 18 and the buffer zone gate 13 are all located upstream of the silt dam 02. A water storage channel is formed between the two adjacent watershed mountains 01. The two bank gates 11 are used to be set on both sides of the water storage channel in a one-to-one correspondence. The bank gates 11 extend along a first direction.

[0064] The siltation area gate 18 and the buffer area gate 13 are both arranged in the water storage channel, and the siltation area gate 18 and the buffer area gate 13 are both arranged between the two bank gates 11. In the first direction, the siltation area gate 18 is arranged between the siltation dam 02 and the buffer area gate 13.

[0065] The water storage channel includes a siltation area 19, a buffer area 17 and a planting area 16. The siltation area 19 is located between the siltation dam 02 and the siltation area gate 18. The buffer area 17 is located between the siltation area gate 18 and the buffer area gate 13. The planting area 16 is located on the side of the buffer area gate 13 away from the siltation dam 02.

The water flowing down from the upper body of the watershed will carry a large amount of large branches, shrubs and other debris. The bank gates 11 set on both sides of the water storage channel are used to intercept these branches, shrubs and other debris, and preliminarily filter the water flow to remove the silt in the siltation area 19. If the amount is excessive, it will pass through the siltation area gate 18 and enter the buffer zone 17. The siltation area gate 18 will also filter the water flowing from the siltation area 19 to the buffer zone 17 and intercept larger debris. The buffer zone gate 13 will intercept the water and silt moving from the buffer zone 17 to the planting area 16 to a certain extent, making it difficult for these water flows and silt to have a large impact on the planting area 16, thereby reducing the adverse effects on the growth of crops in the planting area 16. The planting area 16 can be used to plant cash crops such as agricultural crops, which can provide convenience for the breeding and life of local managers, thereby improving the utilization rate of water resources.

For example, the number of bank water pipes 10 set on each side of the bank of the water storage channel can be 3 to 8, or 3, 4, or 5. By setting the bank water pipe 10, the water body preliminarily filtered by the bank gate 11 can be diverted to the silt accumulation area 19, so that when the precipitation is large, the water body flowing down from the water diversion mountain is not easy to cross the gate and directly impact the buffer zone 17 and the plant area, thereby reducing the adverse effects of water impact on the plant area.

The manhole cover gap capping 38 is used to cooperate with the port of the well body after the manhole cover 24 is removed, so that debris can fly out of the well body 23 when the spiral blade 37 rotates to clear.

[0078] Optionally, the silt dam system provided in the embodiment of the present application also includes a water level monitor 20 and a flood peak monitor 21, both of which are communicatively connected to the data collection processor 22, and the data collection processor 22, the water level monitor 20 and the flood peak monitor 21 are all installed at the top of the stepped body 09. In the embodiment of the present application, the water level monitor 20 preferably includes an electronic water gauge with equal precision of 0.5 cm and a signal transmitter. The electronic water gauge can be customized in range, and different customized ranges are selected for different silt dams 02. The electronic water gauge is made of stainless steel and contains a processor. The electronic water gauge measures the water level behind the dam, and the processor of the water level monitor 20 analyzes the water level changes and rainfall, and the signal transmitter sends the analysis results to the data collection processor 22; the main function of the flood peak monitor 21 is to monitor the flood peak during the flood season, and the water level height at the highest flood level in previous years is input into the flood peak monitor 21 (Nanjing Zhongzhiyan Measurement and Control Technology Technology Co., Ltd., HFT-1 model), set up a monitor to compare and analyze the current water level with the flood levels of previous years in real time, judge whether a flood disaster is likely to occur, and send the analysis results to the data collection processor 22, so as to make decisions and early warnings in advance; the data collection processor 22, the main function is to collect and process the signals and data sent by the siltation monitor 28, the water level monitor 20, the flood peak monitor 21, etc., make decisions on how to deal with the siltation of drainage wells, extract the empirical relationship between rainfall and water level changes and flood peak changes, make judgments on various situations, issue processing instructions, and realize automatic control.

[0079] Preferably, the silt dam system provided in the embodiment of the present application also includes a drip irrigation system 03 and a soil condition detector 06 for detecting soil salt content, water content, soil temperature, pH value and soil stability. The soil condition detector 06 is installed inside the watershed mountain 01, at the shallow surface of the ground below the ecological restoration system 05 and the drip irrigation system 03. The number and spacing of the installations are determined according to the length and slope of the slopes on both sides of the watershed mountain 01. Generally, they are arranged at 5 to 10 meters. The main function is to monitor the salt content (salt content less than 0.5% is within the normal range), water content (50% to 70% is suitable for crop growth), soil temperature, pH value, soil stability, etc. inside the soil, and send the monitoring data to the data collection center. Processor 22; The main function of this component is to provide the entire smart system 04 with the drought conditions of the soil. If it is lower than the minimum water storage capacity of vegetation such as sea buckthorn and caragana, the entire smart system 04 will issue a command to drip irrigate the vegetation on the hillside. When the irrigation volume reaches the predetermined requirement (stop when the water penetrates 10 to 20 cm from the root), the irrigation will be stopped. At the same time, the growth conditions of the vegetation in the feedback system can be monitored by temperature, pH and nutrient components (the sensor uses the existing sensor ZZY-3), so that the technicians can manage it in time. The drip irrigation system 03 is installed on the watershed mountain 01 and the lower layer of the ecological restoration system 05. Its main function is to provide water for the ecological restoration system 05 and irrigate the economic crops in the ecological restoration area. After receiving the soil drought signal, it provides water for the ecological restoration system 05 to irrigate the economic crops.

[0080] Based on the above embodiments of the silt dam system, the present application further provides an embodiment of a control method for the silt dam system, which is executed by the data collection processor 22 mentioned in the above embodiments.

[0081] See also Figure 8 The control method of the silt dam system specifically includes the following contents:

[0082] Step 110: receiving soil drought monitoring data collected by a soil condition detector installed inside the watershed mountain; Step 120: judging whether the soil is currently in drought condition based on the soil drought monitoring data; if so, executing step 130: controlling the drip irrigation system preset in the silt dam system to perform drip irrigation operation; if not, returning to step 110.

[0083] In step 110, soil condition detectors 06 are installed inside the watershed mountain 01, in the shallow surface layer of the ground below the ecological restoration system 05 and the drip irrigation system 03. The number and spacing of the detectors are determined based on the length and slope of the slopes on both sides of the watershed mountain 01, and are generally arranged at 5 to 10 meters.

[0084] In one or more embodiments of the present application, soil drought monitoring data includes: salt content inside the soil (salt content less than 0.5% is within the normal range), water content (50% to 70% is suitable for crop growth), soil temperature, pH value, soil stability, etc.

[0085] In step 120, a specific method for determining whether the soil is currently in a drought condition based on the soil drought monitoring data may be as follows: determining whether there is currently a drought condition based on preset threshold ranges corresponding to different types of soil drought monitoring data. For example, if any one of the salt content, water content, soil temperature, pH value, and soil stability inside the soil does not meet the corresponding preset threshold or threshold range, it is determined that the soil is currently in a drought condition.

[0086] For example, if the salt content is greater than or equal to 0.5%, it can be determined that the current soil is in a drought state; for another example, if the water content is less than 50%, it can be determined that the current soil is in a drought state.

[0087] Step 210: If a drainage well blockage signal is received from a blockage monitor preset in the silt dam system, the nozzle preset in the silt dam system is controlled to spray a dredging agent into the well body of the drainage well according to the level corresponding to the drainage well blockage signal and / or the spiral dredging component preset in the silt dam system is controlled to perform a spiral dredging operation on the drainage well.

[0088] In step 210, when the clogging monitor 28 detects clogging in the well body 23, the clogging monitor 28 transmits the clogging signal to the data collection processor 22. The data collection processor 22 first determines whether it is a normal level drainage well clogging signal or an excessive level drainage well clogging signal based on the identification of the clogging signal. If it is the former, the spiral dredging component preset in the silt dam system is controlled to perform spiral dredging operations on the drainage well; if it is the latter, the water pump is controlled to spray the dredging agent in the dredging agent storage box 25 into the well body 23 through the nozzle 27. At the same time, it can be selected whether to control the spiral dredging component preset in the silt dam system to perform spiral dredging operations on the drainage well, thereby dredging the drainage well.

[0089] Step 310: Receive water level monitoring data collected by a water level monitor preset in the silt dam system; Step 320: Determine whether the water level is too high based on the water level monitoring data. If so, execute step 330: Control the stepped water release device preset in the siltation area to perform drainage operations; if not, return to step 310.

[0090] In step 310, the water level monitoring data may include data on changes in the water level behind the dam and data on changes in rainfall; correspondingly, in step 320, the specific implementation of judging whether the water level is currently too high based on the water level monitoring data may be: if one of the data on changes in the water level behind the dam and the data on changes in rainfall exceeds a preset threshold or threshold range, it is judged that the water level is currently too high.

[0091] Step 410: If a flood peak signal collected by a flood peak monitor preset in the silt dam system is received, the shore gate preset in the siltation area is controlled to perform water interception and filtering operations according to the flood peak signal.

[0092] In order to further illustrate the control method of the above-mentioned silt dam system, the present application also provides a specific application example of the control method of the silt dam system. The control method of the silt dam system can be a smart system, see Fig. 9 In this intelligent system, the water level monitor can also be called a behind-the-dam water level monitor, the shore gate can also be called a flushing channel gate, the stepped water release device can also be called a stepped water release system, the nozzle can also be called a dredging agent releaser, and the spiral dredging assembly can also be called a spiral dredging device.

[0093] In addition, before executing the above-mentioned smart system, the following preparations must be performed:

[0094] 1. Instrument and equipment inspection: Before installing the instruments, conduct technical inspections on all instruments to ensure that the instruments are operating normally and that the entire system can be used stably for a long time. Check whether each system is working properly and whether the line connections are normal.

[0095] 2. Plant selection: Plants need to be carefully selected before planting, and plants that are suitable for the climate of the silt dam area, easy to cultivate, and have high economic value should be selected.

[0096] 3. Selection of unclogging agent (solvent): The unclogging agent added to the drainage well should be a solvent mainly composed of anaerobic microorganisms to ensure environmental friendliness.

[0097] 4. Instrument layout: All instruments are laid out according to the above embodiments, paying attention to the differences in the layout positions of the instruments to ensure that the instruments are installed in reasonable positions and operate normally.

[0098] 5. Inspection of drainage wells and spillways: Check whether the drainage wells and spillways in the silted areas are unobstructed to ensure that they can drain water and silt normally.

[0099] 6. Final inspection: Conduct a second inspection of the construction area to retest whether the previous instrument and equipment inspections are accurate and whether the entire system can operate normally, so as to achieve the goal of rigor and efficiency.

[0100] The above-mentioned implementation methods are only general implementation methods of the present invention. During the test, the order can be adjusted in real time according to the test plan. The present invention can use the silt dam to conserve water sources, nurture economic crops in silted areas, and convert the ecological benefits generated by ecological restoration into economic benefits. At the same time, the system of "one basin water nurtures an entire basin ecology" can achieve a substantial increase in water utilization, precise water use, precise water collection, and water recycling. In addition, the present invention can achieve the ecological regeneration benefits of fragile geological areas from point to surface, use a silt dam to achieve a basin or local ecological regeneration, and use several silt dams to achieve several ecological regeneration zones. The later ecological zones are gradually connected in series, and finally the ecological restoration of fragile geological areas is achieved, effectively reducing the soil and water loss in the Jizi Bay of the Yellow River, and promoting the high-quality development of the Yellow River Basin. It realizes the combination of ecological measures and engineering measures, and the simultaneous implementation of slope management and channel management.
