Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, specifically to a method, apparatus, computer equipment, medium, and product for stratified water intake of gates. Background Technology

[0002] Existing hydraulic gate systems employ two methods for water intake: conventional gates take water from the bottom layer, while stacked beam gates take water from the surface layer. This lack of flexibility in the water intake process is problematic. For example, conventional gates can only take water from the low-temperature bottom layer, while stacked beam gates can only take water from the high-temperature surface layer. The intermediate water layer is thus neglected, limiting the intake to either surface or deep water, and failing to achieve flexible water intake from the intermediate layer. Summary of the Invention

[0003] In view of this, the present invention provides a method, apparatus, computer equipment, medium and product for layered water intake of a sluice gate, in order to solve the problem of inflexible water intake of sluice gates in the prior art.

[0004] In a first aspect, the present invention provides a layered water intake method for a gate, applied to a curtain-type gate. The curtain-type gate includes a first gate unit, a second gate unit, and a third gate unit arranged vertically from top to bottom. The first and third gate units are used to adjust the water intake depth in the vertical direction, and the second gate unit is used to adjust the water intake flow rate in the horizontal direction. The method includes:

[0005] Acquire historical data of the water body upstream of the curtain gate. The historical data includes different depth values ​​of the upstream water body and the distance between the different depth values ​​and the curtain gate.

[0006] A vertical water temperature equation for the upstream water body is established based on different depth values ​​of the upstream water body and the distance between different depth values ​​and the curtain gate.

[0007] The integral parameters in the vertical direction and the integral parameters in the horizontal direction are determined based on the preset target water intake temperature and the vertical water temperature equation of the upstream water body, respectively.

[0008] The adjustment ranges of the first gate unit, the second gate unit, and the third gate unit are determined based on the integral parameters in the vertical direction and the integral parameters in the horizontal direction, respectively.

[0009] The layered water intake method for sluice gates provided by this invention establishes a vertical water temperature equation by acquiring historical water data upstream of the curtain-type sluice gate, which can accurately depict the variation of water temperature with depth and distance from the sluice gate. Based on this, integral parameters are determined by combining a preset target water intake temperature, thereby determining the adjustment range of each sluice gate unit and achieving precise control of the water intake temperature. Compared with traditional water intake methods, this invention provides precise water temperature regulation and flexible water intake, effectively avoiding negative impacts on downstream ecology and production caused by unsuitable water temperatures, such as ensuring suitable survival temperatures for fish and meeting the specific water temperature requirements of industrial production. The unique structural design of the curtain-type sluice gate allows the first and third sluice gate units to adjust the vertical water intake depth, while the second sluice gate unit adjusts the lateral water intake flow rate. Combined with the layered water intake method, the water intake depth, flow rate, and water temperature can be flexibly adjusted according to different downstream water demand, solving the problem of inflexible water intake in existing sluice gate technologies.

[0010] In one optional implementation, a vertical water temperature equation for the upstream water body is established based on different depth values ​​of the upstream water body and the distance between these different depth values ​​and the curtain-type gate, including:

[0011] The water temperature data corresponding to different depths in the upstream water body were obtained, and linear regression analysis was performed on the water temperature data corresponding to different depths to obtain the coefficient of linear change of temperature with depth.

[0012] The magnitude of the change in water temperature and gate distance is calculated based on the water temperature data corresponding to different depths of the upstream water body and the distance to the curtain gate.

[0013] A vertical water temperature equation for the upstream water body is established based on different depth values ​​of the upstream water body, the distance between different depths and the curtain gate, the coefficient of linear temperature change with depth, the magnitude of water temperature change with gate distance, and preset parameters for controlling the rate of temperature change.

[0014] In one alternative implementation, the vertical water temperature equation for the upstream water body is expressed by the following formula:

[0015] ;

[0016] in, T 0 represents the surface temperature or a reference temperature; It's the water depth; It is the distance between the gates; a It is a coefficient that indicates the linear change of temperature with depth; b This indicates the magnitude of the change in water temperature relative to the distance from the gate; c It is a parameter that controls the rate of temperature change.

[0017] The stratified water intake method for gates provided by this invention effectively uncovers the linear law of water temperature variation with depth through linear regression, avoiding subjective assumptions and ensuring that the coefficient of temperature variation with depth has a solid mathematical basis. It calculates the magnitude of water temperature change with gate distance separately, and combines this with preset parameters to control the rate of temperature change, comprehensively considering factors affecting water temperature distribution from multiple dimensions. This refined parameter determination method fully considers the influence of the spatial relationship between the water body and the gate on water temperature, constructing equations based on actual upstream water depth values, corresponding water temperature data, and distances to the gate. These data directly originate from the actual water environment, ensuring that the established vertical water temperature equation closely matches the actual situation. It has good adaptability to curtain gate application scenarios with different hydrological conditions and geographical locations, effectively guiding water temperature control during stratified water intake. If deviations are found between the equation and actual water temperature in practical applications, the data acquisition and parameter calculation stages can be specifically checked. Whether it's adding new influencing factors or improving data processing and parameter calculation methods, it's relatively convenient and easy to optimize and extend the vertical water temperature equation.

[0018] In one optional implementation, the integral parameters in the vertical direction and the integral parameters in the horizontal direction are determined based on the preset target water intake temperature and the vertical water temperature equation of the upstream water body, respectively, including:

[0019] Based on the downstream water demand and water quality requirements of the curtain gate, the target water intake temperature is determined.

[0020] An equation model relating the target water intake temperature to the pre-defined lateral influence range of the curtain-type gate and the vertical water temperature equation of the upstream water body is constructed.

[0021] Based on the equation model relating to the target water intake temperature, the integral parameters in the vertical direction and the integral parameters in the horizontal direction are determined respectively.

[0022] In one alternative implementation, the equation model relating to the target water intake temperature is expressed by the following formula:

[0023] ;

[0024] in, For the target water intake temperature, To pre-determine the lateral influence range of the curtain-type sluice gate in the water intake direction. The integral parameter in the vertical direction represents the boundary in the vertical direction. The integral parameter in the lateral direction represents the boundary in the lateral direction.

[0025] The stratified water intake method for gates provided by this invention first determines the target water intake temperature based on the preset water demand and water quality requirements downstream of the curtain gate, ensuring that the integral parameters in subsequent calculations revolve around actual needs. Whether meeting the specific water temperature requirements of industrial production or ensuring suitable water temperatures for agricultural irrigation and ecological replenishment, it is guided by actual needs. By pre-setting the lateral influence range of the curtain gate's water intake and the vertical water temperature equation of the upstream water body, an equation model is constructed to establish an equation relationship with the target water intake temperature. This model integrates the gate's water intake characteristics, water temperature distribution patterns, and target temperature requirements, transforming complex practical problems into calculable mathematical relationships. It provides a scientific framework for accurately determining integral parameters. Determining the vertical and lateral integral parameters based on the equation model comprehensively considers the spatial distribution changes of water temperature and the lateral and vertical influencing factors during water intake. Compared to simple estimation or empirical values, this model-based calculation method can more accurately derive integral parameters, thus providing a reliable basis for accurately controlling the gate's adjustment range and achieving precise stratified water intake.

[0026] In one optional implementation, the first gate unit is an upper roller shutter gate, the second gate unit includes a symmetrically arranged left curtain gate and a right curtain gate, and the third gate unit is a lower roller shutter gate.

[0027] The adjustment ranges of the first gate unit, the second gate unit, and the third gate unit are determined based on the integral parameters in the vertical direction and the integral parameters in the horizontal direction, respectively, including:

[0028] The adjustment ranges of the upper roller shutter, lower roller shutter, left curtain shutter, and right curtain shutter are determined based on the integral parameters in the vertical and horizontal directions, respectively.

[0029] In one optional embodiment, the adjustment ranges of the upper roller shutter, the lower roller shutter, the left curtain gate, and the right curtain gate are respectively expressed by the following formulas:

[0030] ;

[0031] in, This refers to the adjustment range of the upper roller shutter. This refers to the adjustment range of the lower roller shutter. The adjustment range for the left-side curtain gate. This refers to the adjustment range of the right-hand curtain gate.

[0032] The stratified water intake method for gates provided by this invention determines the adjustment range of the upper and lower roller shutter gates and the left and right curtain gates by using vertical and horizontal integral parameters, respectively, enabling precise control of the water intake temperature within the target range. The vertical integral parameters, corresponding to the adjustment of the upper and lower roller shutter gates, allow for precise selection of water bodies at appropriate depths based on the water temperature distribution along the depth direction. The horizontal integral parameters, corresponding to the adjustment of the left and right curtain gates, allow for reasonable control of the water intake flow rate and range based on horizontal water temperature variations, ensuring that the extracted water temperature meets downstream water demand and avoiding negative impacts on downstream ecology and production due to unsuitable water temperatures. The upper and lower roller shutter gates can flexibly adjust the vertical water intake depth, while the left and right curtain gates can precisely control the horizontal water intake flow rate. The two work together to maximize the efficiency of the gate system during stratified water intake, significantly improving the flexibility and accuracy of water intake compared to traditional gate structures and adjustment methods.

[0033] Secondly, the present invention provides a layered water intake device for a gate, applied to a curtain-type gate. The curtain-type gate includes a first gate unit, a second gate unit, and a third gate unit arranged vertically from top to bottom. The first gate unit and the third gate unit are used to adjust the water intake depth in the vertical direction, and the second gate unit is used to adjust the water intake flow rate in the horizontal direction. The device includes:

[0034] The historical data acquisition module is used to acquire historical data of the water body upstream of the curtain gate. The historical data includes different depth values ​​of the upstream water body and the distance between the different depth values ​​and the curtain gate.

[0035] The vertical water temperature equation establishment module is used to establish the vertical water temperature equation of the upstream water body based on different depth values ​​of the upstream water body and the distance between different depths and the curtain gate.

[0036] The integral parameter determination module is used to determine the integral parameters in the vertical direction and the integral parameters in the horizontal direction based on the preset target water intake temperature and the vertical water temperature equation of the upstream water body.

[0037] The adjustment range determination module is used to determine the adjustment range of the first gate unit, the second gate unit, and the third gate unit based on the integral parameters in the vertical direction and the integral parameters in the horizontal direction, respectively.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Temperature is a crucial physical factor in water bodies, directly impacting other water quality parameters and the survival and development of biological communities. For example, in lakes, rising water temperatures accelerate the growth and reproduction of phytoplankton and animals, increasing the risk of eutrophication. Similarly, high-head reservoirs, after impoundment, alter the hydraulic and thermodynamic conditions of the original river channel, causing temperature stratification. Since power generation requires relatively low intake points, the discharge of water from the power station results in the release of low-temperature water from the lower layers, leading to delayed spawning of fish downstream and "chilling injury" to crops along the banks. In conclusion, monitoring, researching, and scientifically managing water body temperature plays a vital role in protecting the ecological environment and improving water quality. Therefore, sampling and studying water at different depths in rivers, lakes, and reservoirs is of significant importance.

[0051] Existing sluice gates have two types of water intake: conventional hydraulic sluice gates take water from the bottom layer, while stacked beam sluice gates take water from the surface layer. This is not flexible enough in the water intake process. This invention provides a stratified water intake method for sluice gates. Unlike conventional sluice gates, this method uses a curtain-type sluice gate with bidirectional rolling shutters to take water in layers. Based on the production and living requirements of the downstream, the left and right curtain-type sluice gates in the curtain-type sluice gate can flexibly take water from the middle layer of water, thereby improving the flexibility of the sluice gate water intake process.

[0052] According to an embodiment of the present invention, a method for stratified water intake of a gate is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0053] This embodiment provides a tiered water intake method for a gate, applicable to the aforementioned curtain-type gate. The curtain-type gate includes a first gate unit, a second gate unit, and a third gate unit arranged vertically from top to bottom. The first and third gate units are used to adjust the water intake depth in the vertical direction, and the second gate unit is used to adjust the water intake flow rate in the horizontal direction. In this embodiment, as... Figure 4 and Figure 5As shown, the first gate unit is an upper roller shutter gate 11, the third gate unit is a lower roller shutter gate 12, the second gate unit includes a left curtain gate 13 and a right curtain gate 14, and the curtain gate also includes a gate storage unit, a drive unit 19, a traction unit 20 and a control unit.

[0054] The gate storage unit is used to store the gates of the first, second and third gate units that are not underwater during the adjustment process. The gate storage unit includes an upper storage chamber 15, a lower storage chamber 16, a left storage chamber 17 and a right storage chamber 18. The upper storage chamber 15 is used to store the upper roller shutter gate 11, the lower storage chamber 16 is used to store the lower roller shutter gate 12, the left storage chamber 17 is used to store the left curtain gate 13, and the right storage chamber 18 is used to store the right curtain gate 14.

[0055] The drive unit 19 is used to drive the first, second and third gate units to work, including driving the upper roller shutter gate to roll up and down, the lower roller shutter gate to roll up and down, the left curtain gate to open and close left and right, and the right curtain gate to open and close left and right.

[0056] The traction unit 20 includes a first traction unit and a second traction unit. For upper and lower roller shutter gates, the first traction unit consists of door slots on both sides, used to traction and correct the working path of the upper and lower roller shutter gates. For left and right curtain gates, the second traction unit is used to traction and correct the working path of the left and right curtain gates.

[0057] The control unit controls the drive unit to adjust and operate the upper roller shutter gate 11, lower roller shutter gate 12, left curtain gate 13 and right curtain gate 14 according to the downstream water intake demand, so as to achieve the purpose of ecological water intake.

[0058] The upper roller shutter gate 11 and the lower roller shutter gate 12 are roller shutters made of flexible or hinged panels, respectively wound onto rollers installed in the upper storage chamber 15 and the lower storage chamber 16. The rollers are supported by a support frame and bearings, and a drive unit (motor and reduction gear) is connected to the rollers to drive the roller shutters to roll up and down. Vertical door groove guide rails are provided on both sides of the roller shutters, and pulleys or rollers are installed in the guide rails to reduce friction and ensure smooth vertical opening and closing and accurate positioning of the roller shutters. The left curtain gate 13 and the right curtain gate 14 are located on both sides of the water intake and are stored in the side storage chambers by rollers or sliding devices. Both the left curtain gate 13 and the right curtain gate 14 adopt flexible curtain or hinged panel structures, and their horizontal opening or retraction is controlled by a drive unit (motor and gear mechanism). Horizontal guide rails and chutes are provided at the top and bottom of the water intake to support the edges of the gates, and pulleys are installed in the lower guide rail to support the weight of the gates and ensure stable horizontal movement.

[0059] The upper storage chamber 15, lower storage chamber 16, left storage chamber 17, and right storage chamber 18 are all fixedly installed on the main structure of the water intake through a support frame. The roller, door groove, and guide rail are precisely connected to the outlets of the upper storage chamber 15, lower storage chamber 16, left storage chamber 17, and right storage chamber 18 to achieve smooth entry and exit of the gate and reliable storage, and the whole is sealed and waterproof.

[0060] Each gate has a corresponding reel connected to an independent motor, which drives the gate to move via reduction gears or a transmission chain. A position sensor is installed at the end of the motor shaft to provide real-time feedback on the gate's position. Based on the sensor signals, the control unit coordinates the movement of each gate through automatic control logic and a human-machine interface to ensure precise adjustment of the vertical and horizontal opening of the water intake, achieving stratified and precise water intake.

[0061] Figure 1 This is a flowchart of a stratified water intake method for a gate according to an embodiment of the present invention, as follows: Figure 1 As shown, the process includes the following steps:

[0062] Step S101: Obtain historical data of the upstream water body of the curtain gate. The historical data includes different depth values ​​of the upstream water body and the distance between the different depth values ​​and the curtain gate.

[0063] Specifically, a large amount of historical data needs to be collected, covering information on the upstream water body of the intake gate in different seasons and at different times. This data includes the values ​​of the water depth z at various depths in the upstream water body, the measured water temperature values ​​at each depth, and the distance x between the corresponding point and the gate. At the same time, it is also necessary to record factors that may affect the water temperature, such as weather conditions and upstream water flow rate, for subsequent analysis and screening to ensure the accuracy and validity of the data.

[0064] Step S102: Establish the vertical water temperature equation of the upstream water body based on different depth values ​​of the upstream water body and the distance between different depth values ​​and the curtain gate.

[0065] Specifically, based on the physical understanding of water temperature distribution and past research experience, a vertical water temperature equation is constructed for the upstream water body with respect to different depths (water depth z) and distance x from the gate. That is, the vertical water temperature equation describes the relationship between temperature and water depth z and distance x from the gate. Based on this equation, and combined with the downstream preset water demand and water quality requirements to determine the target intake temperature, the vertical and horizontal integration parameters can be determined through integration calculations in the flow and lateral directions. Step S103: Based on the preset target intake temperature and the vertical water temperature equation of the upstream water body, the vertical and lateral integration parameters are determined respectively.

[0066] Specifically, we collaborate with relevant departments such as water resources, environmental protection, and agriculture to gain a deep understanding of the actual water demand downstream. This includes the specific temperature and quality requirements for industrial production, such as the need for cooling water within a specific temperature range in certain manufacturing industries to ensure stable production processes; the need for suitable water temperatures for agricultural irrigation, as different crops have varying sensitivities to water temperature at different growth stages; and the ecological protection needs of downstream river organisms for survival and reproduction, such as the strict temperature requirements for fish spawning and reproduction. Simultaneously, based on national and local water quality standards, we determine the target water intake temperature, comprehensively balancing various factors to ensure that the water temperature and quality meet both production and living needs while guaranteeing the health and stability of the downstream ecological environment.

[0067] The integration of the vertical water temperature equation of the upstream water body in both the vertical and lateral directions essentially represents a comprehensive consideration of the water temperature throughout the entire intake area. However, the actual water environment presents numerous uncertainties, such as changes in meteorological conditions and the randomness of upstream water inflow. These factors can affect the accuracy of the vertical water temperature equation and the integration results. Therefore, uncertainty analysis is necessary. This involves using methods such as Monte Carlo simulations to repeatedly and randomly change the parameters and boundary conditions (e.g., meteorological data) in the vertical water temperature equation of the upstream water body, calculating the corresponding integration parameters, obtaining the range and probability distribution of the integration parameters, and assessing the degree of uncertainty. Simultaneously, sensitivity analysis should be conducted to determine which parameters in the vertical water temperature equation have the most significant impact on the integration parameters. This allows for focused monitoring of these key parameters in practical applications, improving the reliability and adaptability of the stratified water intake scheme.

[0068] Step S104: Determine the adjustment range of the first gate unit, the second gate unit, and the third gate unit based on the integral parameters in the vertical direction and the integral parameters in the horizontal direction, respectively.

[0069] Specifically, the upper and lower roller shutter gates achieve flexible water intake of the vertical water body by adjusting the roller shutter depth in the vertical direction; the left and right curtain gates achieve flow regulation during the water intake process by adjusting in the horizontal direction. The adjustment ranges of the upper and lower roller shutter gates, as well as the adjustment ranges of the left and right curtain gates, are determined based on the integral parameters in the vertical direction and the integral parameters in the horizontal direction, respectively.

[0070] The layered water intake method for gates provided in this embodiment establishes a vertical water temperature equation by acquiring historical water data upstream of the curtain-type gate, which can accurately depict the variation of water temperature with depth and distance from the gate. Based on this, integral parameters are determined by combining a preset target water intake temperature, thereby determining the adjustment range of each gate unit and achieving precise control of the water intake temperature. Compared with traditional water intake methods, this invention provides precise water temperature regulation and flexible water intake, effectively avoiding negative impacts on downstream ecology and production caused by unsuitable water temperatures, such as ensuring suitable survival temperatures for fish and meeting the specific water temperature requirements of industrial production. The unique structural design of the curtain-type gate allows the first and third gate units to adjust the vertical water intake depth, while the second gate unit adjusts the horizontal water intake flow rate. Combined with the layered water intake method, the water intake depth, flow rate, and water temperature can be flexibly adjusted according to different downstream water demand, solving the problem of inflexible water intake in existing sluice gate technologies.

[0071] This embodiment provides a tiered water intake method for a gate, applicable to the aforementioned curtain-type gate. The curtain-type gate includes a first gate unit, a second gate unit, and a third gate unit arranged vertically from top to bottom. The first and third gate units are used to adjust the water intake depth in the vertical direction, and the second gate unit is used to adjust the water intake flow rate in the horizontal direction. In this embodiment, as... Figure 4 and Figure 5 As shown, the first gate unit is an upper roller shutter gate 11, the third gate unit is a lower roller shutter gate 12, the second gate unit includes a left curtain gate 13 and a right curtain gate 14, and the curtain gate also includes a gate storage unit, a drive unit 19, a traction unit 20 and a control unit.

[0072] The gate storage unit is used to store the gates of the first, second and third gate units that are not underwater during the adjustment process. The gate storage unit includes an upper storage chamber 15, a lower storage chamber 16, a left storage chamber 17 and a right storage chamber 18. The upper storage chamber 15 is used to store the upper roller shutter gate 11, the lower storage chamber 16 is used to store the lower roller shutter gate 12, the left storage chamber 17 is used to store the left curtain gate 13, and the right storage chamber 18 is used to store the right curtain gate 14.

[0073] The drive unit 19 is used to drive the first, second and third gate units to work, including driving the upper roller shutter gate to roll up and down, the lower roller shutter gate to roll up and down, the left curtain gate to open and close left and right, and the right curtain gate to open and close left and right.

[0074] The traction unit 20 includes a first traction unit and a second traction unit. For upper and lower roller shutter gates, the first traction unit consists of door slots on both sides, used to traction and correct the working path of the upper and lower roller shutter gates. For left and right curtain gates, the second traction unit is used to traction and correct the working path of the left and right curtain gates.

[0075] The control unit controls the drive unit to adjust and operate the upper roller shutter gate 11, lower roller shutter gate 12, left curtain gate 13 and right curtain gate 14 according to the downstream water intake demand, so as to achieve the purpose of ecological water intake.

[0076] Figure 2 This is a flowchart of a stratified water intake method for a gate according to an embodiment of the present invention, as follows: Figure 2 As shown, the process includes the following steps:

[0077] Step S201: Obtain historical data of the water body upstream of the curtain gate. This historical data includes different depth values ​​of the upstream water body and the distance between these different depth values ​​and the curtain gate. For details, please refer to [link to relevant documentation]. Figure 1 Step S101 of the illustrated embodiment will not be described again here.

[0078] Step S202: Establish the vertical water temperature equation of the upstream water body based on different depth values ​​of the upstream water body and the distance between different depth values ​​and the curtain gate.

[0079] Specifically, step S202 includes:

[0080] Step S2021: Obtain water temperature data corresponding to different depths in the upstream water body, and use linear regression to perform linear regression analysis on the water temperature data corresponding to different depths to obtain the coefficient of linear change of temperature with depth.

[0081] Specifically, the preprocessed water temperature data corresponding to different depths were compiled into a dataset, with different depths (water depth z) as independent variables and water temperature T as the dependent variable, and a univariate linear regression model was selected. (in (This is a constant term). Univariate linear regression models are suitable for analyzing the linear relationship between two variables and can intuitively reflect the trend of water temperature change with depth.

[0082] The least squares method is used to estimate the parameters of a linear regression model. The core idea of ​​the least squares method is to determine the optimal model parameters by minimizing the sum of squared errors between the observed values ​​and the model's predicted values. The specific calculation process is as follows: Let the observed data points be... ( , (Number of data points), the model's predicted value is Then the sum of squared errors is Through the analysis of Regarding respectively and Find the partial derivatives, set them to zero, solve the system of equations, and obtain the coefficients. and The estimated value.

[0083] Calculate the coefficient of determination for a linear regression model Indicators such as root mean square error (RMSE) are used to evaluate the model's fit. The closer the value is to 1, the better the model fits the data; the smaller the RMSE, the smaller the error between the model's predictions and actual observations. If the model fit is poor, consider introducing other influencing factors (such as water flow velocity, dissolved oxygen content, etc.) to construct a multiple linear regression model, or use a nonlinear regression model to further optimize the model and improve the coefficient of linear temperature variation with depth. The accuracy.

[0084] Step S2022: Calculate the magnitude of the change in water temperature and gate distance based on the water temperature data corresponding to different depths of the upstream water body and the distance to the curtain gate.

[0085] Specifically, water temperature data at the same depth but different distances from the gate are grouped. For example, water temperature data at a depth of 2 meters, at distances of 5 meters, 10 meters, and 15 meters from the gate are grouped together. Statistical analysis is performed on each group of data, calculating its mean, standard deviation, and other statistical measures to describe the central tendency and dispersion of the data.

[0086] Standard deviation or coefficient of variation is used to measure the magnitude of water temperature variation with distance from the gate. Standard deviation reflects the dispersion of data relative to the mean; the larger the standard deviation, the greater the variation in water temperature with distance from the gate. The coefficient of variation, on the other hand, is the ratio of the standard deviation to the mean, eliminating the influence of data magnitude and making it more suitable for comparing the dispersion of different groups of data.

[0087] The specific calculation formula is: Standard Deviation coefficient of variation (in (This is the mean of the data set). By calculating the standard deviation or coefficient of variation of the data at different depths, the amplitude b of the change in water temperature with respect to the gate distance is obtained, which is used to describe the fluctuation characteristics of water temperature in the lateral direction (distance from the gate).

[0088] Step S2023: Establish the vertical water temperature equation of the upstream water body based on different depth values ​​of the upstream water body, the distance between different depths and the curtain gate, the coefficient of linear temperature change with depth, the magnitude of water temperature change with gate distance, and preset parameters for controlling the rate of temperature change.

[0089] Specifically, based on the coefficient of linear temperature variation with depth calculated earlier. The magnitude of the change in water temperature and gate distance (b), and the preset parameter c for controlling the rate of temperature change (initial values ​​can be set based on experience or preliminary experiments, and adjusted during model verification and optimization), combined with surface temperature or reference temperature. T 0. Construct the vertical water temperature equation for the upstream water body.

[0095] The stratified water intake method for gates provided in this embodiment constructs equations based on information such as the actual depth values ​​of upstream water, corresponding water temperature data, and distances from the gate. This data directly originates from the actual water environment, ensuring that the established vertical water temperature equation closely reflects the actual situation. It exhibits good adaptability to curtain gate applications under different hydrological conditions and geographical locations, effectively guiding water temperature control during stratified water intake. If deviations are found between the equation and the actual water temperature in practical applications, the data acquisition and parameter calculation processes can be specifically examined. Adding new influencing factors or improving data processing and parameter calculation methods is relatively convenient, facilitating the optimization and expansion of the vertical water temperature equation.

[0096] This embodiment provides a tiered water intake method for a gate, applicable to the aforementioned curtain-type gate. The curtain-type gate includes a first gate unit, a second gate unit, and a third gate unit arranged vertically from top to bottom. The first and third gate units are used to adjust the water intake depth in the vertical direction, and the second gate unit is used to adjust the water intake flow rate in the horizontal direction. In this embodiment, as...

[0100] The control unit controls the drive unit to adjust and operate the upper roller shutter gate 11, lower roller shutter gate 12, left curtain gate 13 and right curtain gate 14 according to the downstream water intake demand, so as to achieve the purpose of ecological water intake.

[0101] Figure 3 This is a flowchart of a stratified water intake method for a gate according to an embodiment of the present invention, as follows: Figure 3 As shown, the process includes the following steps:

[0102] Step S301: Obtain historical data of the water body upstream of the curtain gate. This historical data includes different depth values ​​of the upstream water body and the distance between these different depth values ​​and the curtain gate. For details, please refer to [link to relevant documentation]. Figure 2 Step S201 of the illustrated embodiment will not be described again here.

[0103] Step S302: Establish the vertical water temperature equation for the upstream water body based on different depth values ​​and the distance between these depth values ​​and the curtain gate. For details, please refer to [link to relevant documentation]. Figure 2 Step S202 of the illustrated embodiment will not be described again here.

[0104] Step S303: Based on the preset target water intake temperature and the vertical water temperature equation of the upstream water body, determine the integral parameters in the vertical direction and the integral parameters in the horizontal direction, respectively.

[0105] Specifically, step S303 includes:

[0106] Step S3031: Determine the target water intake temperature based on the preset water demand and water quality requirements downstream of the curtain gate.

[0107] Specifically, we engaged in in-depth communication with multiple departments, including water resources, environmental protection, agriculture, and industry. In the industrial sector, we understood the specific requirements of different production enterprises for cooling water temperature, such as the precise temperature requirements of steam circulation systems in thermal power plants and the stringent standards for constant cooling water temperature in electronic chip manufacturing. In agriculture, we investigated the suitable irrigation water temperatures for different crops at various growth stages, such as the different water temperature requirements for rice during transplanting and tillering stages. The environmental protection department could provide the water temperature ranges required for the survival and reproduction of aquatic organisms in downstream rivers; for example, salmon are sensitive to water temperature during spawning and require a specific temperature range. Simultaneously, we referenced national and local water quality standards for various types of water use, comprehensively considering the impact of water temperature on water quality indicators (such as dissolved oxygen content and pH).

[0108] The collected water demand data were systematically organized and categorized according to water type, season, and time of day. Data analysis tools were used to identify the commonalities and differences in water temperature requirements under different demands, and water temperature demand distribution and trend charts were created to visually present the characteristics of downstream water demand for water temperature. For example, analysis revealed that the upper limit requirements for water temperature for industrial cooling water and agricultural irrigation water in summer are relatively similar, while ecological water replenishment has a relatively stable range of water temperature requirements throughout the year.

[0109] Based on a comprehensive analysis of various demands, a target water intake temperature that meets the majority of water demand was determined using methods such as weighted averaging and priority ranking. If downstream water use is largely driven by industrial production and has strict temperature requirements, the weight of industrial water demand should be appropriately increased; if ecological protection is the priority, then the water temperature required for river ecology should be guaranteed first. At the same time, a certain buffer zone for temperature fluctuations should be reserved to cope with uncertainties in actual water use.

[0110] Step S3032: Construct an equation model relating the target water intake temperature to the preset influence range of the curtain gate in the lateral direction and the vertical water temperature equation of the upstream water body.

[0111] Specifically, the influence range of the curtain-type gate in the lateral direction of water intake is preset. This parameter can be determined through on-site measurements, reference to similar engineering experience data, or by using physical model experiments and numerical simulations. Combined with the established upstream water body vertical temperature equation, which describes the distribution of water temperature in the vertical and horizontal directions, the target water intake temperature is [not specified]. As constraints on the model, it is ensured that the constructed model can meet the core needs of downstream water use.

[0112] Based on the principle of mathematical integration, the water temperature equation is integrated in both the vertical and horizontal directions. In the vertical direction (water depth z-direction), the integration range must cover the possible water intake depth range; in the horizontal direction (distance x from the gate), the integration range is the preset horizontal influence range of the water intake. The water temperature at different locations within the water intake area is integrated to obtain an equation model relating it to the target water intake temperature.

[0113] The equation model relating the target water intake temperature to the target water intake temperature is expressed by the following formula:

[0114] (2);

[0115] in, For the target water intake temperature, To pre-determine the lateral influence range of the curtain-type sluice gate in the water intake direction. The integral parameter in the vertical direction represents the boundary in the vertical direction. The integral parameter in the lateral direction represents the boundary in the lateral direction.

[0116] Step S3033: Based on the equational relationship model with the target water intake temperature, determine the integral parameters in the vertical direction and the integral parameters in the horizontal direction, respectively.

[0117] Specifically, for the constructed equation model, an appropriate numerical integration method is selected for solving, such as the trapezoidal rule, Simpson's rule, or Gaussian rule. The integration step size and computational nodes are determined based on the complexity of the model and the required computational accuracy. For example, for a relatively complex water temperature distribution equation, the Gaussian rule can be used; by appropriately selecting integration nodes and weights, high computational accuracy can be obtained with less computation.

[0118] Iterative algorithms, such as the Newton-Raphson iteration method and the bisection method, are used to solve for the integration parameters. First, the integration parameters (the integration parameters in the vertical direction) are given. That is, the vertical boundary (i.e., water depth z); the integral parameter in the horizontal direction. The initial estimated value of the horizontal boundary (i.e., the distance x from the gate) is substituted into the equation model for calculation. Then, the calculated result is compared with the target water intake temperature. The values ​​of the integral parameters are compared and adjusted according to the magnitude of the error. The results are then substituted back into the model for calculation. This process is repeated until the error between the calculated result and the target temperature meets the preset accuracy requirements.

[0119] Step S304: Determine the adjustment range of the first gate unit, the second gate unit, and the third gate unit based on the integral parameters in the vertical direction and the integral parameters in the horizontal direction, respectively.

[0120] Specifically, step S304 includes:

[0121] Step a: Determine the adjustment range of the upper roller shutter, the lower roller shutter, the left curtain shutter, and the right curtain shutter based on the integral parameters in the vertical and horizontal directions, respectively.

[0122] Specifically, this study delves into the structural design of the upper and lower roller shutter gates and the left and right curtain gates, clarifying their movement mechanisms and their impact on water flow. The upper and lower roller shutter gates change the water intake depth through vertical raising and lowering, and their range of movement is closely related to the vertical water temperature distribution. The opening and closing of the left and right curtain gates affects the water intake flow rate and the lateral water temperature distribution. Combining fluid mechanics principles, this study analyzes the changes in flow velocity and direction under different gate regulation states, and the impact of these changes on water temperature distribution.

[0123] The adjustment ranges of the upper roller shutter, the lower roller shutter, the left curtain shutter, and the right curtain shutter are expressed by the following formulas:

[0124] (3);

[0125] in, This refers to the adjustment range of the upper roller shutter. This refers to the adjustment range of the lower roller shutter. The adjustment range for the left-side curtain gate. This refers to the adjustment range of the right-hand curtain gate.

[0126] The stratified water intake method provided in this embodiment determines the adjustment range of the upper and lower roller shutter gates and the left and right curtain gates by using vertical and horizontal integral parameters, respectively, enabling precise control of the water intake temperature within the target range. The vertical integral parameters, corresponding to the adjustment of the upper and lower roller shutter gates, allow for precise selection of water at appropriate depths based on the water temperature distribution along the depth direction. The horizontal integral parameters, corresponding to the adjustment of the left and right curtain gates, allow for reasonable control of the water intake flow and range based on horizontal temperature variations, ensuring that the extracted water temperature meets downstream water demand and avoiding negative impacts on downstream ecology and production due to unsuitable water temperatures. The upper and lower roller shutter gates can flexibly adjust the vertical water intake depth, while the left and right curtain gates can precisely control the horizontal water intake flow. The two work together to maximize the efficiency of the gate system during stratified water intake, significantly improving the flexibility and accuracy of water intake compared to traditional gate structures and adjustment methods.

The curtain-type gate design avoids the cumbersome and troublesome process of opening and closing the gate. Finally, the operating control range of the curtain-type stratified water intake gate is determined by the temperature distribution curve of the upstream water body, ensuring reliable water intake. As a stratified water intake gate, the curtain-type gate enables precise control of the reservoir discharge water temperature, meeting the needs of the downstream habitat and reducing negative impacts on downstream river organisms and the aquatic environment.
