[0051] Ecological flow discharge facilities: special buildings used to discharge ecological flows, or buildings that can also discharge ecological flows, generate water for power generation, allow fish to pass through, or allow navigation.

[0052] Hydropower stations are comprehensive engineering facilities that convert water energy into electrical energy. Constrained by factors such as early development concepts, technology, economy and management levels, some small hydropower stations have secondary ecological problems such as hydrological rhythm disturbance, river ecological barriers, and habitat fragmentation during development and operation. Downstream rivers are prone to dehydration, especially during the dry season. Therefore, hydropower stations need to use discharge facilities, such as modifying river dams, water diversion systems, or adding ecological units, to ensure that the downstream flow meets the ecological needs of the downstream river, that is, to meet the ecological flow. In related technologies, due to the wide variety of ecological flow discharge facilities and the number of small hydropower stations across the country as many as 41,000, the calculation accuracy of the ecological flow of small hydropower stations is low, making it difficult to effectively manage the ecological flow of hydropower stations.

[0057] Figure 1 This is an optional flow chart of the method for monitoring the ecological flow of a hydropower station provided in an embodiment of the present application. Figure 1 The method may include but is not limited to steps S110 to S130.

[0058] Step S110: Acquire discharge facility information data, so as to acquire facility monitoring data from a preset database according to the discharge facility information data.

[0059] Step S120: Calculate the ecological flow rate based on the facility monitoring data and the discharge facility information data to obtain first ecological flow rate data.

[0060] Step S130: performing an abnormality analysis based on the first ecological flow data and the facility monitoring data, and generating a hydropower station inspection report.

[0061] During the operation of this specific embodiment, the present invention first obtains discharge facility information data, and then retrieves facility monitoring data from a preset database based on the discharge facility information data. Specifically, the discharge facility information data in this embodiment refers to information data of the hydropower station discharge facility that requires inspection and analysis. Accordingly, the facility monitoring data in this embodiment refers to facility parameters and monitoring data of the flow discharge facility, where facility parameters include discharge pipe length and inner diameter, discharge gate width and opening height, or unit power, etc. In this embodiment, the facility monitoring data is stored in a preset database. Accordingly, the present invention extracts the corresponding facility monitoring data from the preset database using the obtained discharge facility information data. Next, the present invention performs an ecological flow calculation based on the facility monitoring data and the discharge facility information data to obtain a first ecological flow. Specifically, the present invention determines the corresponding hydropower station discharge facility based on the discharge facility information data, and then determines a calculation method for the ecological flow calculation. The ecological flow calculation is performed based on the facility monitoring data to obtain the first ecological flow data. The first ecological flow data refers to the flow discharge volume of the current discharge facility calculated based on the facility monitoring data. Finally, the embodiment of the present invention performs an anomaly analysis based on the first ecological flow data and the facility monitoring data, generating a hydropower station inspection report. Specifically, the embodiment of the present invention combines the calculated flow discharge volume and the corresponding facility monitoring data to analyze whether there are any anomalies with the hydropower station's flow discharge facilities, such as whether the discharge flow meets the ecological flow rate or whether there are any related discharge issues. The hydropower station inspection report is then generated, thereby providing support for the supervision and management of the hydropower station's ecological flow.

[0062] In some embodiments of the present invention, obtaining discharge facility information data to obtain facility monitoring data from a preset database according to the discharge facility information data includes but is not limited to the following steps:

[0063] Obtain discharge facility information data, wherein the discharge facility information data includes target hydropower station information and corresponding discharge facility type.

[0064] The facility monitoring data is obtained from a preset database based on the target hydropower station information, wherein the facility monitoring data corresponds to the type of discharge facility.

[0065] In this specific embodiment, the embodiment of the present invention first obtains the discharge facility information, and then obtains the facility monitoring data from the preset database based on the obtained target hydropower station information. Specifically, the discharge facility information data in the embodiment of the present invention includes the target hydropower station information and the corresponding discharge facility type. Among them, the embodiment of the present invention divides the hydropower stations that need to implement the ecological flow task into regions, for example, Figure 2As shown, the system is divided into cities, districts, towns, and subdistricts. In this embodiment of the present invention, the hydropower station that requires inspection and monitoring is determined based on the target hydropower station information. Furthermore, in this embodiment of the present invention, the discharge facility type refers to the type of discharge facility corresponding to the hydropower station, such as a spillway, spillway, eco-unit, eco-pump, or weir. Accordingly, this embodiment of the present invention determines the target hydropower station based on the target hydropower station information and then obtains the corresponding facility monitoring data for the target hydropower station from a preset database. In this embodiment of the present invention, the facility monitoring data corresponds to the discharge facility type. For example, when the discharge facility type is a spillway, the facility monitoring data in this embodiment of the present invention includes data such as total hydraulic head, pipe length, and pipe inner diameter. Alternatively, when the discharge facility type is a flat-bottomed flat gate in a spillway, the facility monitoring data in this embodiment of the present invention includes data such as total hydraulic head (upstream and downstream water level difference), gate width, and gate opening height. Accordingly, in this embodiment of the present invention, the facility monitoring data is pre-stored in a preset database.

[0066] In some embodiments of the present invention, before performing ecological flow calculation based on facility monitoring data and discharge facility information data to obtain first ecological flow data, the hydropower station ecological flow supervision and management method provided by the embodiment of the present invention further includes but is not limited to the following steps:

[0067] Dynamically monitor the corresponding discharge facility data based on the target hydropower station information.

[0068] The facility monitoring data is updated according to the discharge facility data, and the updated facility monitoring data is stored in a preset database.

[0069] In this specific embodiment, the present invention first dynamically monitors the corresponding discharge facility data based on the target hydropower station information, updates the facility monitoring data based on the discharge facility data, and stores the updated facility monitoring data in a preset database. Specifically, the discharge facility data in this embodiment corresponds to the facility monitoring data. This embodiment first determines the hydropower station to be monitored based on the target hydropower station information, and then uses the corresponding monitoring module to perform real-time monitoring to obtain the discharge facility data. It will be readily understood that when the facility monitoring data is obtained from the preset database in this embodiment, the corresponding data may be updated and changed, such as changes in the total head data of the discharge pipe. Therefore, before performing ecological flow calculations, this embodiment first dynamically monitors the corresponding discharge facility data to determine whether the facility monitoring data needs to be updated. Accordingly, when it is determined that the facility monitoring data needs to be updated, it is updated using the discharge facility data, and the updated facility monitoring data is stored in the preset database. In this embodiment, the discharge facility data can be obtained by monitoring the corresponding monitoring module installed at the target hydropower station, or by monitoring by relevant personnel during inspections.

[0070] It should be noted that in some embodiments of the present invention, the preset database utilizes a multi-source data storage structure. Specifically, the preset database in embodiments of the present invention stores a power plant information table, a discharge facility table, a parameter record table, and a calculation record table. Accordingly, in embodiments of the present invention, the power plant information table stores information such as the power plant's statistical code, name, geographic location (city, county (district), town, or street), and management unit. The discharge facility table is associated with the power plant's statistical code and stores the discharge facility type. The parameter record table is associated with the power plant's statistical code and stores calculation parameters (e.g., D, L, and n for the discharge pipe; N, h, and η for the eco-generator) and parameter acquisition time. The calculation record table is associated with the power plant's statistical code and stores calculation results (flow rate Q, flow velocity v) and calculation time. Accordingly, in embodiments of the present invention, data fields in the preset database are standardized. For example, all parameters are defined in unified units (e.g., meters, seconds, and kilowatts), and calculation parameters are stored in JSON format, supporting the expansion of special fields for different types of facilities. Furthermore, in embodiments of the present invention, data in the preset database is updated using an incremental synchronization strategy. Changes are recorded with time stamps between the local and cloud databases to avoid data conflicts. Local storage is supported in offline mode, with automatic synchronization to the cloud upon reconnection to ensure data integrity. Furthermore, in this embodiment of the present invention, once the power plant and facility type is determined, the system automatically loads the latest parameter records for that facility to reduce duplication of input. Furthermore, after parameter modifications are made, historical calculations retain the original parameter versions, while new calculations use the updated parameters to ensure data traceability. Changes to power plant information (such as facility renovations) trigger parameter table status updates, which are synchronized to relevant modules.

[0071] In some embodiments of the present invention, performing ecological flow calculation based on facility monitoring data and discharge facility information data to obtain first ecological flow data includes but is not limited to the following steps:

[0072] The corresponding ecological flow calculation module is determined according to the type of discharge facility, wherein the discharge facility type includes one of a discharge pipe, a discharge gate, an ecological unit, an ecological pump, and a flow measuring weir.

[0073] The discharge facility information data and facility monitoring data are input into the ecological flow calculation module to calculate and obtain the first ecological flow data.

[0074] In this specific embodiment, the embodiment of the present invention first determines the corresponding ecological flow calculation module according to the type of discharge facility, and then inputs the discharge facility information data and facility monitoring data into the ecological flow calculation module to calculate and obtain the first ecological flow data. Specifically, the discharge facility type in the embodiment of the present invention includes one of a discharge pipe, a discharge gate, an ecological unit, an ecological pump, and a flow measuring weir. Exemplarily, when it is determined that the discharge facility is a discharge pipe (siphon), the embodiment of the present invention inputs the obtained discharge facility information data and facility monitoring data, such as the total head (H), the pipe length (L), and the pipe inner diameter (D), into the ecological flow calculation module to calculate and obtain the first ecological flow data. The calculation process is shown in the following formula (1):

[0075]

[0076] Where n represents the noise rate, and the preset default value is 0.013, which can be customized and adjusted according to actual needs; ξ represents the local head loss coefficient, and x represents the outflow coefficient, and the preset default values ​​are both 1, which can also be customized and adjusted according to actual needs; Q represents the required flow rate, in m 3 / s; R represents the hydraulic radius, A represents the cross-sectional area, which is calculated by the inner diameter D of the pipe.

[0077] In addition, when the discharge facility type is determined to be a flat-bottomed flat gate in a spillway, the embodiment of the present invention performs an ecological flow calculation based on the acquired facility monitoring data, such as the total water head (H), gate width (B), and gate opening height (e). In the embodiment of the present invention, the flat-bottomed flat gate orifice flow coefficient μ is calculated according to the following formula (2). When e / H ≥ 0.03, e / H is directly substituted into the calculation; when e / H < 0.03, e / H is directly used as 0.03 to calculate the μ value.

[0078] μ=0.454(e / H) -0.138 (2)

[0079] Next, the embodiment of the present invention calculates the flow rate of the flat bottom flat plate gate type sluice gate, as shown in the following formula (3):

[0080]

[0081] In addition, for flat-bottomed radial gates, the angle (θ) between the gate bottom edge tangent and the horizontal line, the gate opening height (e), the total water head (upstream and downstream water level difference) (H), and the gate width (B) are obtained. Among them, the angle (θ) between the gate bottom edge tangent and the horizontal line is in degrees; the gate opening height (e), the total water head (upstream and downstream water level difference) (H), and the gate width (B) are in meters (m). Accordingly, the orifice flow coefficient μ of the flat-bottomed radial gate in the embodiment of the present invention is calculated by the following formula (4). When e / H ≥ 0.03, e / H is directly used in the calculation; when e / H < 0.03, e / H is directly taken as 0.03 to calculate the μ value.

[0082] μ=1-0.0166θ 0.723 -(0.582-0.0371θ 0.547 )e / H (4)

[0083] Accordingly, the embodiment of the present invention calculates the flow rate of the flat-bottomed radial gate type spillway as shown in the above formula (3).

[0084] In addition, if Figure 3 As shown, when the discharge facility type is a curved practical weir flat gate, the orifice flow coefficient μ of the curved practical weir flat gate in the embodiment of the present invention is calculated by the following formula (5):

[0085]

[0086] Next, the embodiment of the present invention calculates the flow rate of the curved practical weir flat gate type spillway through the above formula (3).

[0087] In addition, when the discharge facility type is a curved practical weir arc gate of a spillway, the embodiment of the present invention is calculated by the following formula (6):

[0088]

[0089] Then, the embodiment of the present invention calculates the flow rate of the curved practical weir radial gate type spillway through the above formula (3).

[0090] In addition, when the discharge facility type is an ecological unit, the facility monitoring data obtained by the embodiment of the present invention includes the unit power (N) and water head (h) of each unit. Among them, the unit power (N) is in kilowatts (kW), and the water head (h) is in meters (m). Accordingly, the default value of the efficiency η in the embodiment of the present invention is 0.8, which can be customized and adjusted according to actual needs, and the value range is between 0-1. Among them, the flow calculation formula of the ecological unit in the embodiment of the present invention is shown in the following formula (7):

[0091]

[0092] Among them, Q i represents the flow rate of the i-th group of ecological units, and Q represents the total flow rate of multiple groups of ecological units.

[0093] In addition, when the discharge facility type is an ecological pump, the facility monitoring data obtained by the embodiment of the present invention includes the single-machine electrical power (N) and the pumping head (h). Among them, the unit of the single-machine electrical power (N) is kilowatt (kW), and the unit of the pumping head (h) is meter (m). Accordingly, the default value of the efficiency η in the embodiment of the present invention is 0.6, which can be customized and adjusted according to actual needs, and the value range is between 0-1. Among them, the flow calculation formula of the ecological pump in the embodiment of the present invention is shown in the following formula (8):

[0094] Q=ηN / gh (8)

[0095] In addition, when the discharge facility type is a flow measuring weir, the embodiment of the present invention divides the flow measuring weir into rectangular thin-walled weir, triangular thin-walled weir, and sharp-edged rectangular wide-top weir. Accordingly, when the ecological flow discharge monitoring facility is a rectangular thin-walled weir, the facility monitoring data obtained includes the weir width (b) and the total head (h), in meters (m). Among them, the default value of the flow coefficient (CD) in the embodiment of the present invention is preset to 0.6, which can be customized and modified according to actual conditions. Accordingly, the flow of the rectangular thin-walled weir type flow measuring weir in the embodiment of the present invention is calculated by the following formula (9):

[0096]

[0097] Accordingly, for the triangular thin-walled weir, the preset default value of the discharge coefficient (CD) in the embodiment of the present invention is 0.6, and the default value of the weir angle θ is 90 degrees, which can be customized and modified according to actual conditions.

[0098] In the embodiment of the present invention, the flow rate of the triangular thin-wall weir is calculated by the following formula (10):

[0099]

[0100] Accordingly, for a sharp-edged rectangular wide-crowned weir, the default value of the flow combination coefficient (C) in the embodiment of the present invention is preset to 1, and the setting can be customized and modified according to actual conditions. In the embodiment of the present invention, the flow rate of the sharp-edged rectangular wide-crowned weir is calculated by the following formula (11):

[0101]

[0102] In some embodiments of the present invention, performing anomaly analysis based on the first ecological flow data and the facility monitoring data to generate a hydropower station inspection report includes but is not limited to the following steps:

[0103] The first ecological flow data is compared and analyzed with the ecological flow certified value to obtain the data deviation value.

[0104] According to the target hydropower station information, the abnormal information of the hydropower station is obtained through the preset supervision and inspection module.

[0105] Generate a hydropower station inspection report based on the hydropower station abnormal information and data deviation values.

[0106] In this specific implementation, the embodiment of the present invention compares and analyzes the first ecological flow data with the approved ecological flow value to obtain a data deviation value. Specifically, the approved ecological flow value in the embodiment of the present invention refers to the ecological flow value of the corresponding hydropower station calculated and determined according to the hydrological method of relevant regulations. Among them, in the daily supervision process, relevant regulations require that the daily average ecological flow discharge value (i.e., the actual discharge value) of each hydropower station be no less than the approved ecological flow value (i.e., the supervision value or target value). Accordingly, the embodiment of the present invention analyzes and judges the calculated first ecological flow data with the approved ecological flow value to determine whether the discharge of ecological flow meets the requirements and obtains the data deviation value. Then, the embodiment of the present invention obtains the abnormal information of the hydropower station through the preset supervision and inspection module based on the information of the target hydropower station, and then generates a hydropower station inspection report based on the abnormal information of the hydropower station and the data deviation value. Specifically, the embodiment of the present invention first determines the target hydropower station by screening the target hydropower station information, and obtains the basic information of the target hydropower station (name, location, management unit) and the associated discharge facility list (such as discharge pipes, ecological units, etc.) from the preset database. Accordingly, the embodiment of the present invention obtains abnormal information of the target hydropower station, such as discharge problems, monitoring problems and other problems, such as Figure 4 As shown. In addition, the abnormal information of the hydropower station obtained in the embodiment of the present invention also includes specific description information of the abnormal problem, such as "the opening height of the spillway is insufficient, the measured e=0.2m, and the target value needs to be ≥0.5m". Then, the embodiment of the present invention generates a hydropower station inspection report by linking and collating the acquired abnormal information of the hydropower station and the data deviation value of the ecological flow discharge. Exemplarily, the embodiment of the present invention loads the latest parameters of the current discharge facility (such as the opening height e of the spillway, the total head H) and the historical calculation results (design flow Q), and generates a comparative analysis. For example, the embodiment of the present invention performs parameter comparison to obtain the difference between the measured parameters and the target value, such as e _实际 =0.2m&e _目标=0.5m. At the same time, the embodiment of the present invention issues a flow deviation alarm. For example, when the measured flow is lower than 80% of the approved ecological flow value, the system marks it as a "red alert". Then, after completing the problem record, that is, after obtaining the abnormal data of the hydropower station, the embodiment of the present invention integrates the relevant data, such as power station information (statistical code, name, location, management unit, etc.), problem summary (classification, description, related discharge facilities), parameter comparison table (target value, measured value, deviation percentage), rectification suggestions (such as "adjust the gate opening height to ≥0.5m"), etc., and records the implementation of the problem rectification and the completion time of the rectification, thereby generating a corresponding hydropower station inspection report.

[0107] In some embodiments of the present invention, after obtaining abnormal information of the hydropower station through a preset supervision and inspection module based on the target hydropower station information, the method for supervising and managing the ecological flow of the hydropower station provided by the embodiment of the present invention further includes but is not limited to the following steps:

[0108] Based on the target hydropower station information and hydropower station abnormality information, the corresponding hydropower station abnormal image data is obtained through a preset camera module. Among them, the hydropower station inspection report is generated by integrating the hydropower station abnormal image data, hydropower station abnormality information and data deviation values.

[0109] In this specific embodiment, the embodiment of the present invention obtains the corresponding abnormal image data of the hydropower station through a preset camera module based on the target hydropower station information and the abnormal information of the hydropower station, and then integrates the abnormal image data of the hydropower station to generate a hydropower station inspection report. Specifically, after obtaining the abnormal information of the hydropower station, the embodiment of the present invention obtains the on-site pictures of the target hydropower station (abnormal image data of the hydropower station) through a preset camera module in combination with the target hydropower station information to review and record the abnormal information of the hydropower station, thereby generating a hydropower station inspection report based on the abnormal image data of the hydropower station, the abnormal information of the hydropower station and the data deviation value. For example, Figure 4 As shown, the preset camera module in the embodiment of the present invention can be a camera module of a mobile terminal. For example, the embodiment of the present invention calls the camera module of the mobile terminal to shoot the current status of the discharge facilities, monitoring and surveillance equipment or the ecological flow public notice board (such as the opening status of the spillway, the installation position of the water level meter, etc.), thereby obtaining the corresponding abnormal image data of the hydropower station. At the same time, the embodiment of the present invention can also import the saved on-site photos (such as historical inspection archives) into the local album through the local album. Accordingly, the embodiment of the present invention adds annotations to the acquired images, such as circling the damaged parts of the discharge facilities, the relationship between the monitoring section and the dam site, etc.

[0110] In some embodiments of the present invention, the method for monitoring and managing the ecological flow of a hydropower station provided by the embodiments of the present invention further includes but is not limited to the following steps:

[0111] Obtain the desired transformation parameter data.

[0112] The second ecological flow data is calculated by the ecological flow calculation module according to the desired transformation parameter data.

[0113] Conduct facility modification verification analysis based on the second ecological flow data and generate a discharge facility modification report.

[0114] In this specific embodiment, the embodiment of the present invention first obtains the expected transformation parameter data, and calculates the second ecological flow data through the ecological flow calculation module according to the expected transformation parameter data, and then performs facility transformation verification analysis according to the second ecological flow data to generate a discharge facility transformation report. Specifically, the expected transformation parameter data in the embodiment of the present invention refers to the expected data for the transformation of the relevant hydropower station. Accordingly, in the process of ecological flow supervision and management of a hydropower station, it is often necessary to transform the discharge facilities of the hydropower station, and to verify the parameters of the transformation. Therefore, the embodiment of the present invention inputs the acquired expected transformation parameter data into the corresponding ecological flow calculation module to calculate the flow discharge data of the flow discharge facility of the hydropower station under the expected transformation parameter data, that is, the second ecological flow data. For example, Figure 5 As shown, Figure 5 This figure shows a schematic diagram of parameter modifications for calculating a flat-bottomed flat gate in an embodiment of the present invention. This embodiment then compares and verifies the second ecological flow data with target flow data, such as the certified ecological flow value, to determine whether the second ecological flow data meets flow discharge requirements. This generates a discharge facility modification report, facilitating adjustments to discharge facility dimensions during ecological flow discharge facility modifications and providing data support.
