Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water conservancy, in particular to an auxiliary reservoir capacity recovery method for water diversion and beach scouring. BACKGROUND

[0002] As an important water conservancy facility, reservoirs play a key role in flood control, water supply, irrigation, etc. However, the accumulation of large amounts of sediment carried by rivers in the backwater area and beach of the reservoir tail is a common and serious problem. Not only does the accumulation directly lead to the continuous loss of effective reservoir capacity, weakening its regulation and storage capacity, but it can also affect power output, raise the upstream flood level, and even cause water quality deterioration.

[0003] Currently, for the treatment of reservoir beach sedimentation, traditional methods such as mechanical dredging, emptying and sand discharge have limitations such as high operation cost, long construction period, possible interruption of normal reservoir functions, and insufficient flexibility for large-area beach treatment. Water diversion and beach scouring is an economic and environmentally friendly method that uses the natural power of water flow to scour sediment bodies, but traditional water diversion and beach scouring operations rely heavily on experience-based decision-making, lack scientificity, and are not precise in choosing the timing, area, and intensity of scouring, resulting in low scouring efficiency, unsatisfactory reservoir capacity recovery, and an inability to respond to dynamic changes in water flow conditions and sedimentation during the scouring process.

[0004] In addition, when the scouring equipment is working in sediment-laden water flow for a long time, the inlet of the equipment is easily blocked by sediment, affecting the continuous and stable operation of the equipment, and even causing damage to the equipment.

[0005] Therefore, there is an urgent need in the art for a reservoir capacity recovery method that can make intelligent decisions, precise operations, adaptive adjustments, and ensure continuous and stable operation of the equipment, to efficiently and economically solve the problem of reservoir beach sedimentation.

Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure can be more thoroughly understood and so that the scope of the present disclosure can be conveyed to those skilled in the art. It should be noted that the embodiments and features in the present disclosure can be combined with each other as long as there is no conflict. The present disclosure will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0020] The above scenarios are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.

[0021] In some embodiments of the present application, an auxiliary reservoir capacity recovery method for water diversion and beach scouring includes the following steps: coupling a reservoir scheduling model, determining the optimal scouring timing and target area of the reservoir beach surface according to the model prediction results; deploying a mobile automatic scouring monitoring system to the target area, the system including a movable pump station; automatically adjusting the scouring intensity of the movable pump station based on real-time flow conditions; performing water diversion and beach scouring operations through the movable pump station, using the impact force of the water flow to remove the beach surface deposits; real-time monitoring of the beach surface deposit morphology and changes in reservoir capacity during the scouring process; dynamically optimizing the scouring operation parameters according to the monitoring results to achieve the recovery of the reservoir capacity.

[0022] Therefore, the system used in the method has a central control center, which is deployed with a reservoir scheduling model combined with data analysis software; a mobile automatic scouring monitoring system, the core of which is a mobile pump station. The pump station is provided with a pump station main body, and a modularly designed diesel engine or electric pump group, which is convenient to be transported to the target beach by a transport vehicle; a flow regulating module composed of a frequency converter or a throttle controller or an electric valve, which is used to accurately control the water flow and pressure; a scouring monitoring module including a flow rate sensor installed near the water inlet and outlet of the pump station, which monitors the environmental flow rate and scouring jet velocity in real time, and a water level sensor arranged around the pump station, which monitors the water level change in the operation area.

[0023] The accumulated thickness detection device uses a single-beam depth sounder installed on a remotely controllable small floating platform to periodically scan the beach topography; the image acquisition unit uses a high-definition camera to monitor the beach scouring condition and the outlet working state; the data communication module uses wireless network to upload the monitoring data to the central control center in real time, and receives control instructions from the center; the self-cleaning filter mechanism is arranged at the water inlet of the pump station, and the fixed filter assembly is composed of a plurality of fixed plates, and the movable filter assembly is composed of a plurality of movable plates with the same spacing and slightly lower height. The movable plates are connected with an elastic spring mechanism through connecting rods.

[0024] Specifically, the coupled reservoir scheduling model includes obtaining historical hydrological data, topographic data, accumulated distribution data and weather forecast data of the reservoir; inputting the data into the reservoir scheduling model; simulating the flow movement characteristics of the reservoir under different hydrological conditions through the reservoir scheduling model; predicting the key time window of the beach accumulation scouring, and determining the time window as the best scouring opportunity. The determination of the target area includes: analyzing the beach accumulation thickness, accumulation distribution range and beach slope information through the reservoir scheduling model; identifying the area with accumulated sediment and hydraulic scouring conditions; combining the target of reservoir capacity recovery, setting the identified area as the target area for priority scouring, and planning the scouring operation sequence of each area.

[0025] Referring to Figure 1 It can be seen that the central control center in the method flowchart of the system obtains the hydrological data of the reservoir in the past 10 years, the latest underwater topographic map and the weather forecast data in the next 15 days. These data are input into the reservoir hydrodynamic-sediment coupled scheduling model which has been constructed. The model simulates the flow movement and sediment transport of the reservoir under different future inflow scenarios. The simulation results show the favorable conditions for starting scouring. The model also predicts that the A area and the B area of the beach are the core areas of accumulation. The control center determines the best scouring opportunity accordingly, and can specifically define the A area as the target area for priority scouring, and the B area secondly.

[0026] Specifically, the mobile automatic scour monitoring system comprises a movable pump station body, a flow regulating module, a scour monitoring module and a data communication module; the movable pump station body adopts a modular structure and can be quickly arranged according to the topographic features of the target area. The scour monitoring module comprises a water level sensor, a flow rate sensor, a silt thickness detection device and an image acquisition unit; the scour monitoring module is used for collecting real-time data of the water level, flow rate, silt thickness change and beach surface morphology of the scour area, and uploading the real-time data to the control center through the data communication module.

[0027] Therefore, during the entire operation process, the monitoring data is continuously uploaded. The control center analyzes the silt removal efficiency, the silt volume removed per unit time and the reservoir capacity recovery progress. It is found through analysis that the removal efficiency of a certain sub-area in region A is continuously lower than the preset standard. The control center decides to adjust the scouring sequence and temporarily deploy a pump station to another sub-area with higher removal efficiency. When the monitoring data shows that the reservoir capacity recovery in region A has reached 90% of the expected target, the system gradually reduces the scouring intensity in this area and deploys a pump station to region B to start preliminary operation in advance. The water quality monitoring unit in the system detects that the local water turbidity is temporarily over standard. The system immediately instructs the pump station in this area to stop operation for 10 minutes, resumes operation after the turbidity decreases, and starts the preset water purification auxiliary measure of adding flocculants.

[0028] The automatic adjustment of the scouring intensity based on the real-time water flow conditions comprises: obtaining the real-time water flow rate through the flow rate sensor arranged in the mobile automatic scour monitoring system; combining the silt state information fed back by the silt thickness detection device; calculating the optimal scour flow rate and scour pressure under the current conditions; and controlling the output power and outlet flow rate of the movable pump station through the flow regulating module to realize dynamic adjustment of the scouring intensity.

[0029] The adjustment of the scouring intensity further comprises: when the real-time water flow rate is higher than the preset upper limit, reducing the output power and scour flow rate of the movable pump station to prevent excessive disturbance from causing the reservoir bottom silt to be suspended again; and when the real-time water flow rate is lower than the preset lower limit, increasing the output power and scour flow rate of the movable pump station to ensure effective stripping and transport of the silt.

[0030] Specifically, the water diversion and beach scouring operation adopts a directional scouring mode. By adjusting the jetting direction and angle of the outlet of the movable pump station, the water flow is concentrated on the target silt layer to form a directional erosion channel, and the silt is guided out of the reservoir with the water flow. The dynamic optimization of the scouring parameters includes: the control center receives the real-time monitoring data uploaded by the mobile automatic scouring monitoring system; analyzes the silt removal efficiency and the progress of reservoir capacity recovery; when the silt removal efficiency is lower than the preset standard, the scouring sequence of the target area is adjusted or more movable pump stations are dispatched; when the reservoir capacity recovery reaches the expected target, the scouring intensity is gradually reduced or the scouring operation is terminated; further including: during the scouring operation, the heavy metal concentration and turbidity of the water body in the reservoir area are detected in real time by the water quality monitoring unit; when the detection value exceeds the preset safety threshold, the scouring intensity is adjusted or the scouring operation is suspended, and water purification auxiliary measures are started at the same time to prevent water pollution from spreading.

[0031] Therefore, the operation personnel transport two mobile automatic scouring monitoring system pump stations to the beach A area and quickly arrange them according to the terrain. The scouring operation starts, and the flow rate sensor detects that the environmental flow speed is 0.75 m / s. The depth finder initial scan shows that the average silt thickness in the A area is 2.45 m. The algorithm in the control center calculates the current best scouring flow rate as 300 m 3 / h and the scouring pressure as 0.6 MPa according to these real-time data.

[0032] The flow rate adjustment module receives the instruction and automatically adjusts the pump station to the specified working condition to start directional scouring. The operator adjusts the jetting angle of the outlet through the control terminal so that it impacts the silt layer at an angle of about 30 degrees to form a directional erosion channel. After a period of time, the upstream inflow decreases and the environmental flow speed decreases to 0.4 m / s, which is 0.5 m / s lower than the preset lower limit. The system automatically increases the output power of the pump station to increase the scouring flow rate to 350 m 3 / h to maintain effective scouring force. After a few hours, the rainfall intensity exceeds the expectation, and the environmental flow speed increases to 1.2 m / s, which is 1.0 m / s higher than the preset upper limit. In order to prevent excessive disturbance of the bottom mud, the system automatically reduces the power of the pump station to reduce the scouring flow rate to 250 m 3 / h.

[0033] The application embodiment also provides an auxiliary reservoir capacity recovery system for water diversion and beach scouring, which comprises a mobile automatic scouring monitoring system pump station, and the pump station is provided with a self-cleaning filtering mechanism; the self-cleaning filtering mechanism comprises a fixed filtering assembly and a movable filtering assembly arranged side by side; the movable filtering assembly is used to move in response to the water flow pressure when the silt is blocked, so that the accumulated silt is stripped and discharged into the collecting device arranged in the pump station, thereby realizing self-cleaning of the filtering mechanism.

[0034] Reference Figure 2It can be known that the self-cleaning filtering mechanism 01 is arranged at the water inlet end of the mobile automatic flushing monitoring system pump station, adopts a cylindrical structure matched with the pump station water inlet pipeline, is composed of a fixed filtering assembly 03, a movable filtering assembly 05, an elastic supporting assembly 04, a collecting device 02 and a collecting inlet 06, and each component cooperates to realize the self-filtering and cleaning of the accumulated substances.

[0035] Referring to Figure 3 It can be known that the fixed filtering assembly 03 is a static filtering unit of the mechanism, is arranged in parallel and at intervals by fixed plates, and forms a filtering channel for water flow. Uniformly distributed first through holes are formed on each fixed plate, which can not only ensure smooth water flow, but also intercept weeds, stones, coarse particle silt and other accumulated substances with a volume greater than the through holes. The fixed filtering assembly 03 is fixedly connected with the inner wall of the pump station water inlet pipeline through a flange, the axial length thereof is consistent with that of the movable filtering assembly 05, and the filtering area completely covers the water inlet section.

[0036] The movable filtering assembly 05 is arranged at the water inlet side of the fixed filtering assembly 03, is arranged in parallel and staggered with the fixed filtering assembly 03, is composed of a plurality of moving plates corresponding to the fixed plates, the moving plates are provided with second through holes matched with the first through holes of the fixed plates, the diameters of the second through holes are consistent with those of the first through holes, and when the movable filtering assembly 05 is at an initial position, the second through holes partially overlap the first through holes, so as to ensure the water flow rate during normal filtering. The two ends of the moving plate are movably connected with the mechanism shell through shafts, the shafts are provided with the elastic supporting assembly 04, the elastic supporting assembly 04 is a torsional spring made of stainless steel, one end of the spring is fixed on a fixed seat of the mechanism shell, the other end is clamped with the shaft of the moving plate, and in the initial state, the spring keeps the relative position of the movable filtering assembly 05 and the fixed filtering assembly 03 through the spring force, so as to ensure the stability of the filtering channel.

[0037] Referring to Figure 4 It can be known that the collecting device 02 is arranged below the self-cleaning filtering mechanism 01, is a rectangular box structure with an open top, and can accommodate the stripped accumulated substances in a single cleaning process. The collecting device 02 is communicated with the filtering mechanism body through the collecting inlet 06, the collecting inlet 06 is an inclined opening structure with an inclination angle of 30-45°, the opening width is matched with the width of the movable filtering assembly 05, the upper edge of the opening is flush with the lower end of the movable filtering assembly 05, and the stripped accumulated substances can smoothly slide into the collecting device 02. Four universal wheels are installed at the bottom of the collecting device 02, which facilitates subsequent manual regular removal and cleaning. Drainage holes are formed in the side surface of the collecting device 02, a small amount of water flow carried in the collecting process can be discharged, and accumulated water is avoided to cause the deterioration and odor of the accumulated substances.

[0038] In the actual operation process, the working process of the self-cleaning filtering mechanism 01 is as follows: when the pump station is started, the water flow enters the self-cleaning filtering mechanism 01 from the water inlet, first passes through the moving plate of the movable filtering assembly 05, and the accumulated substances with a volume greater than the second through hole in the water flow are intercepted on the surface of the moving plate. The filtered water flow passes through the second through hole and the first through hole of the fixed filtering assembly 03 to enter the inside of the pump station, thereby realizing the preliminary purification of the water inlet.

[0039] With the continuous operation, the accumulated substances on the surface of the moving plate gradually accumulate, causing the second through hole to be partially or completely blocked, the water flow resistance increases, and the water inlet pressure rises. When the water pressure reaches a threshold value, the pressure of the water flow on the movable filtering assembly 05 overcomes the torsional spring elastic force of the elastic support assembly 04, and the moving plate is pushed to rotate around the rotating shaft to the direction of the collecting device 02, and the rotation angle range is 15-20°.

[0040] During the rotation of the moving plate, since the height of the moving plate is lower than that of the fixed plate of the fixed filtering assembly 03, and the initial state of the two is misaligned, the edge of the fixed plate protrudes from the surface of the moving plate, forming a scraping structure similar to a comb. With the rotation of the moving plate, the edge of the fixed plate moves relative to the surface of the moving plate, and the accumulated substances attached to the moving plate are forced to be stripped. The stripped accumulated substances slide along the inclined surface of the moving plate under the combined action of the water flow impact force and gravity, enter the collecting device 02 through the collecting inlet 06, and are collected.

[0041] When the accumulated substances are stripped, the filtering channel on the surface of the moving plate is re-opened, the water inlet pressure drops to the normal range, the torsional spring of the elastic support assembly 04 releases the stored elastic force, drives the moving plate to rotate in the opposite direction to reset, and returns to the initial relative position with the fixed filtering assembly 03, and enters the normal filtering state again.

[0042] It is not difficult to understand that the entire self-cleaning process does not require external power driving, and is completely dependent on the coordinated action of the water flow pressure and the elastic assembly to realize autonomous circulation, ensure the continuous operation of the pump station in the high-sand water flow environment, avoid shutdown maintenance caused by accumulation and blockage, and significantly improve the continuity and stability of the system operation. It is simple and efficient to operate.
