Description

Technical Field

[0001] This invention relates to the field of power control technology for slag removal equipment in hydropower plants, specifically to an intelligent slag removal power system with modular power supply and unified management. Background Technology

[0002] In the daily operation and maintenance of hydropower dams, intelligent slag removal and manned platform equipment has become the core equipment for cleaning up debris such as floating slag and driftwood in river channels. This type of equipment integrates multiple low-voltage electrical control loads and high-power power execution units, including rotary saws, mounted grab hooks, electrified extendable platforms, gantry crane moving mechanisms, manned platform electrical control units, sensor modules, and remote control systems. The voltage and power requirements of each unit vary significantly. At the same time, dam slag removal operations face the characteristics of humid, dusty, and highly variable water levels and complex working environments. The equipment needs to operate continuously for long periods of time, which places extremely high demands on the stability, endurance, and coordination of the power supply.

[0003] Traditional dam slag removal equipment employs a decentralized power management approach, where low-voltage electrical control loads and high-power power execution units are powered independently without a unified power management system. This approach suffers from several technical drawbacks: First, decentralized power management leads to poor power supply coordination. When multiple high-power power execution units start simultaneously, voltage fluctuations in the power grid can easily cause instability in the power supply to low-voltage electrical control units such as sensors and remote control systems, directly affecting the normal operation of the equipment. Second, the lack of redundancy backup design for each power module means that a single power module failure can paralyze the corresponding load or execution unit, resulting in low overall equipment endurance and operational reliability. Third, the lack of effective real-time fault monitoring and emergency control mechanisms means that power failures cannot be detected and handled in a timely manner, easily leading to equipment damage or even on-site operational safety accidents. Fourth, the power output cannot be dynamically adjusted according to operating conditions, resulting in serious waste of power resources and failing to guarantee the instantaneous power needs of multi-unit collaborative operations.

[0004] Currently, most power management solutions for slag removal equipment on the market are designed for general industrial equipment, without taking into account the working characteristics of dam slag removal equipment and the power requirements of multi-unit collaborative operation. Therefore, they cannot effectively solve the technical problems caused by the aforementioned distributed power supply.

[0005] Therefore, there is an urgent need to develop a modular power management system that is compatible with intelligent dam slag removal and manned platform equipment, so as to achieve efficient power distribution, stable supply and intelligent control, and improve the equipment's power endurance and operational reliability. Summary of the Invention

[0006] To address the aforementioned issues, this invention provides an intelligent slag removal power system with modular power supply unified management. This system solves problems such as unstable power supply, poor endurance, low coordination between units, and weak fault response capabilities caused by the decentralized power supply management of traditional slag removal equipment. It enables unified scheduling, intelligent power allocation, and real-time fault control of the power supply for each low-voltage electrical control load and high-power power execution unit of the slag removal equipment, ensuring the coordinated and stable operation of the decentralized electrical control system and the centralized control system, and adapting to the complex operating conditions of dam slag removal.

[0007] The technical solution of this invention is: A modular power supply unified management intelligent slag removal power system is applied to intelligent slag removal and manned platform equipment in dams. The system includes a separate power supply module, a power supply module, a core control module, a multi-channel power output unit, a fault monitoring unit, and an emergency control unit. Each functional module is integrated into a protective shell adapted to the working conditions of hydropower stations, realizing an integrated modular design that facilitates installation and disassembly, and adapts to the overall modular design requirements of slag removal equipment.

[0008] Preferably, the discrete power supply module is used to supply power to the low-voltage electrical control loads such as the centralized control system, sensor module, and remote control communication unit of the slag removal equipment. It includes several pluggable low-voltage power supply sub-modules, each of which is independent and equipped with an independent voltage regulator and power detection chip. The output voltage of the low-voltage power supply sub-module is adapted to the rated operating voltage of the low-voltage electrical control load of the slag removal equipment and supports hot-swapping replacement, realizing redundancy backup of low-voltage power supply and avoiding the paralysis of low-voltage electrical control load due to the failure of a single sub-module.

[0009] Preferably, the power supply module is used to supply power to high-power power execution units such as rotary saws, grab hooks, extendable platforms, and gantry crane moving mechanisms of the slag removal equipment. It includes a high-power rectifier unit, a power distributor, and an energy storage submodule. The high-power rectifier unit is connected to an industrial-grade AC power supply and converts it into DC power suitable for the high-power power execution units. The power distributor is electrically connected to the core control module and allocates rated power to different power execution units according to the instructions of the core control module. The energy storage submodule is used to replenish power when the power execution units start up at high power momentarily, avoiding voltage fluctuations in the power grid and ensuring power supply stability.

[0010] Preferably, the core control module is the control core of the entire power system, and is electrically connected to the separate power supply module, the power supply module, the multi-channel power output unit, the fault monitoring unit, and the emergency control unit. The core control module includes a microprocessor, a power scheduling algorithm module, and a communication module. The power scheduling algorithm module has a built-in power allocation strategy, which dynamically adjusts the output power of the separate power supply module and the power supply module according to the real-time operating conditions of the slag removal equipment, and reduces the power supply to idle execution units to achieve energy saving and consumption reduction. The communication module communicates bidirectionally with the centralized control system and remote control terminal of the slag removal equipment to realize remote monitoring and command reception of the power system.

[0011] Preferably, the multi-channel power supply output unit includes several independent power supply channels. Each power supply channel is equipped with an independent current transformer and an electronic switch. The current transformer is used to detect the current and voltage parameters of the corresponding power supply channel and transmit the detected parameters to the core control module in real time. The electronic switch is controlled by the core control module to achieve individual power supply control for each electrical control load and power execution unit, which facilitates precise regulation of the power supply status of each unit.

[0012] Preferably, the fault monitoring unit includes an overvoltage detection module, an undervoltage detection module, an overcurrent detection module, and a temperature detection module. The fault monitoring unit is deployed at key power transmission nodes of the separate power supply module, the power supply module, and the multi-channel power output unit. It collects the power parameters and equipment temperature parameters of each node in real time and transmits the monitoring data to the core control module. When the monitored parameters exceed the preset threshold, the fault monitoring unit sends a fault alarm signal to the core control module to achieve real-time fault monitoring.

[0013] Preferably, the emergency control unit includes an emergency power-off module, a backup power switching module, and an emergency communication module. The emergency power-off module is electrically connected to the core control module and the electronic switches of each power supply channel. When it receives a fault command or a remote emergency power-off command from the core control module, it can quickly cut off the power supply to all or a specified power supply channel. The backup power switching module is equipped with a portable backup power supply. When the main power supply is interrupted, it automatically switches to the backup power supply to power the separate power supply module and the emergency communication module, ensuring the basic functions of the centralized control system and remote communication. The emergency communication module is an independent wireless communication module that enables signal transmission in emergency situations when the main communication module fails.

[0014] Furthermore, the core control module also has a data storage function, which can record the operating parameters, fault information and power distribution records of the power system. The stored data can be exported via wired or wireless means, which facilitates the later maintenance of the equipment and fault tracing.

[0015] Furthermore, the core control module can be linked with the sensor fusion system of the slag removal equipment to automatically adjust the power distribution strategy based on the slag removal operation data transmitted by the sensor fusion system. When the sensor detects that multiple high-power power execution units need to work together to handle slag, the core control module sends a command to the power supply module to increase the power supply of the corresponding execution unit and ensure the power needs of the collaborative operation.

[0016] Furthermore, the system also includes a protective housing. The separate power supply module, power supply module, core control module, and fault monitoring unit are all integrated within the protective housing. The protective housing has a protection level suitable for the humid and dusty working conditions of hydropower stations. The housing is equipped with a heat dissipation structure and waterproof wiring ports. The power supply lines of the multi-channel power output unit are connected to external electrical control loads and power execution units through waterproof wiring ports, thereby improving the system's environmental adaptability and service life.

[0017] The beneficial effects of this invention are: 1. This invention solves the problem of poor coordination in traditional distributed power supply by setting up separate power supply modules and power supply modules to provide targeted power to low-voltage electrical control loads and high-power power execution units. It also achieves unified scheduling and intelligent distribution of power supply for the entire system through the core management module, thus realizing efficient power distribution and stable supply and ensuring the coordinated and stable operation of distributed electrical control system and centralized control system.

[0018] 2. The separate power supply module adopts a redundant backup design with pluggable low-voltage power supply sub-modules, which supports hot-swappable replacement. The power supply module is equipped with an energy storage sub-module to achieve instantaneous high-power replenishment, which greatly improves the power supply reliability of the system and the endurance of the equipment, avoids the problem of equipment paralysis caused by the failure of a single module, and is suitable for the long-term continuous operation of dam slag removal equipment.

[0019] 3. This invention integrates a multi-dimensional fault monitoring unit and a multi-functional emergency control unit, which can realize real-time monitoring of power parameters and equipment temperature at key nodes of the power system. It also has functions such as emergency power outage, automatic switching of backup power, and emergency communication, which greatly improves the system's fault response capability and on-site operation safety, and can effectively avoid the risk of power failure under complex working conditions of dams.

[0020] 4. The core control module has a built-in power scheduling algorithm module, which can dynamically adjust the power allocation strategy according to the real-time operating conditions of the slag removal equipment. It also supports linkage with the sensor fusion system to realize intelligent power adjustment, which not only ensures the instantaneous power demand of multi-unit collaborative operation, but also realizes energy conservation and consumption reduction of power resources and improves the utilization rate of power resources.

[0021] 5. The entire system adopts an integrated modular design, with each functional module integrated into a high-protection-level protective shell, which is suitable for the humid and dusty working conditions of hydropower stations. It is also easy to install and disassemble, and is highly compatible with the modular design requirements of intelligent slag removal and manned platforms for dams. At the same time, the core control module has data storage and export functions, which facilitates the later maintenance of equipment, fault tracing, and improvement of operation and maintenance efficiency. Attached Figure Description

[0022] Figure 1 This is a schematic diagram of the overall architecture of the intelligent slag removal power system with modular power supply unified management according to the present invention. Detailed Implementation

[0023] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0024] Example 1 This embodiment describes a modular power supply system for intelligent slag removal, managed in a unified manner. This system is applied to intelligent slag removal and manned platform equipment at hydropower station dams. The equipment integrates a large, high-power rotary saw, a mounted grab hook, an electrified extendable platform, an electric gantry crane mechanism, electrically controlled guardrails for the manned platform, a sensor fusion system (including distance, level, and vision sensors), and a remote control system, among other low-voltage electrical control loads and high-power power execution units. The equipment must operate continuously for extended periods in the humid, dusty, and dynamically changing water conditions of the hydropower station's riverbed. All core modules of this system are integrated within an IP67-rated metal protective enclosure. The outer wall of the enclosure is equipped with aluminum alloy heat dissipation fins, and a waterproof aviation wiring port is provided at the bottom. The power supply lines of the multiple power output units are electrically connected to the external low-voltage electrical control loads and high-power power execution units through the waterproof wiring port. The bottom of the enclosure is equipped with a quick-installation fixing structure, allowing direct docking with the slag removal equipment frame for convenient installation and disassembly.

[0025] In this embodiment, the discrete power supply module is configured with four pluggable low-voltage power supply sub-modules, each with a rated output current of 10A, equipped with a high-precision voltage regulator and an RS485 protocol power detection chip; the high-power rectifier unit of the power supply module is a three-phase full-bridge rectifier structure, the energy storage sub-module uses a 2000F supercapacitor module, and the power distributor is an 8-channel intelligent power distribution structure; the microprocessor of the core control module uses a 32-bit industrial-grade MCU, and the communication module integrates 4G and LoRa dual wireless communication modules; the multi-channel power supply output unit is configured with 12 independent power supply channels, each channel is adapted to a 50A current transformer and an explosion-proof electronic switch; each detection module of the fault monitoring unit uses an industrial-grade sensor chip with a sampling frequency of 10Hz; the portable backup power supply of the emergency control unit is a 24V / 100Ah lithium battery pack, and the emergency communication module is an independent LoRa wireless module with a communication distance of not less than 1km.

[0026] The specific steps for implementing this system are as follows: 1. Power Connection and System Initialization 1.1 Power Supply Connection: The high-power rectifier unit of the power supply module is connected to the industrial-grade AC power supply of the hydropower station through a high-voltage waterproof cable. After three-phase full-bridge rectification and filtering, the rectifier unit converts the AC power into DC power that is compatible with the high-power power execution unit. The output voltage is stabilized at DC 380V. At the same time, the energy storage submodule completes pre-charging and is in standby charging state. 1.2 Low-voltage power supply access: The four pluggable low-voltage power supply sub-modules of the separate power supply module start synchronously. Each sub-module stabilizes the output voltage to 24V DC through a voltage regulator, which matches the rated operating voltage of the low-voltage electrical control loads such as the slag removal equipment control system and sensor modules. The power detection chip collects the remaining power and output current / voltage parameters of each sub-module in real time and transmits the data to the core control module. 1.3 System Self-Test and Initialization: The core control module, fault monitoring unit, and emergency control unit are powered on and started synchronously. The core control module performs a full-link self-test on each module, checking the electrical connection status and hardware working status of each module. After the self-test is completed, the preset power allocation strategy of the power scheduling algorithm module is loaded. The fault monitoring unit enters the detection thresholds of each key power transmission node into the system (overvoltage threshold is 1.2 times the rated voltage, undervoltage threshold is 0.8 times the rated voltage, overcurrent threshold is 1.5 times the rated current, and temperature threshold is 70℃) and enters the real-time monitoring state of all nodes. The backup power switching module and emergency power failure module of the emergency control unit complete initialization and are in standby standby state. The entire initialization process takes no more than 30 seconds. The self-test results are uploaded to the slag removal equipment centralized control system and remote control terminal through the communication module.

[0027] 2. Intelligent power allocation for conventional slag removal operations 2.1 Receiving Operation Instructions: When the slag removal equipment is carrying out routine small-scale slag and floating object retrieval operations, the staff sends operation instructions through the remote control terminal. The instructions are transmitted to the core control module via the communication module. The instructions include that the execution units to be activated for this operation are the attached grab hook and the electric gantry crane moving mechanism, while the other execution units are in an idle state. 2.2 Power Allocation Execution: The core control module sends a power allocation command to the power distributor of the power supply module according to the preset strategy of the power scheduling algorithm module. It allocates 30kW of rated working power to the hook-mounted crane and 15kW of rated working power to the electric gantry crane moving mechanism. At the same time, it reduces the power supply of idle high-power power execution units such as rotary saws and extendable platforms to 500W standby power and shuts down the power supply channel with no power consumption. 2.3 Low-voltage power supply management: The separate power supply module maintains four low-voltage power supply sub-modules connected in parallel to provide a stable 24V DC power supply for low-voltage electrical control loads such as the centralized control system, sensor modules, and remote control communication units. The power detection chip collects the power data of each sub-module every 5 seconds. When the remaining power of a sub-module is less than 20%, the core management module sends a low power reminder to the centralized control system. The staff can hot-swap the low-power sub-module without disconnecting the system power supply, realizing uninterrupted redundancy backup of low-voltage power supply. 2.4 Operational Status Monitoring: The current transformers of the multi-power supply output units monitor the current and voltage parameters of each power supply channel in real time. Every 2 seconds, the monitored data is transmitted to the core control module. The core control module analyzes and processes the data to ensure that the power supply parameters of each starting unit are within the rated range. At the same time, the operational status is uploaded to the remote control terminal in real time to realize the visual monitoring of the operation process.

[0028] 3. Dynamic adjustment of power for multi-unit collaborative operation in large-scale scum treatment 3.1 Operational Data Acquisition: When the visual sensor and distance sensor of the sensor fusion system detects extra-long and extra-large driftwood (diameter ≥ 50cm, length ≥ 3m) in the river, the sensor transmits operational data such as the size and location of the driftwood to the core control module through the centralized control system. It determines that the rotary saw and the attached grab hook need to be started to work together to complete the cutting, grabbing and salvaging of the driftwood. 3.2 Dynamic Power Adjustment: The power scheduling algorithm module of the core control module dynamically adjusts the power allocation strategy according to the working condition data, sends a power increase command to the power supply module, increases the power supply of the rotary saw to 80kW rated working power, maintains the rated working power of the hook-mounted device at 30kW, dynamically allocates 10-20kW power to the electric gantry crane moving mechanism according to the operation requirements, and keeps the remaining idle units in standby power. 3.3 Instantaneous Power Supply Control: When the rotary saw starts, the sudden increase in power can easily cause voltage fluctuations in the power grid. The energy storage submodule of the power supply module receives the power supply command from the core control module 500ms before the rotary saw starts and releases electrical energy synchronously to provide instantaneous power supply to the rotary saw. The power supply current is 200A, which effectively avoids voltage fluctuations in the industrial-grade AC power grid and ensures the power supply stability of low-voltage electrical control loads. 3.4 Collaborative Operation Monitoring: The core control module collects the power supply parameters of the rotary saw, hook, and overhead crane moving mechanism in real time. Based on the operation rhythm of each unit, it dynamically fine-tunes the power distribution. When the rotary saw completes the cutting of driftwood and the hook begins the grabbing operation, the core control module reduces the power supply of the rotary saw to 50kW to ensure sufficient power supply during the grabbing process and realize intelligent power matching for multi-unit collaborative operation.

[0029] 4. Real-time fault monitoring and rapid closed-loop processing 4.1 Real-time monitoring of all nodes: The overvoltage, undervoltage, and overcurrent detection modules of the fault monitoring unit are deployed at key power transmission nodes such as the output end of the separate power supply module, the output end of the power supply module, and the input end of each channel of the multi-channel power supply output unit. The temperature detection module is mounted on the surface of the core components of each power supply module and the core control module. Each detection module collects power parameters (current, voltage) and equipment temperature parameters in real time at a sampling frequency of 10Hz and transmits the monitoring data to the core control module in real time. 4.2 Fault Identification and Alarm: The core control module compares the received monitoring data with the preset threshold in real time. When the current in the power supply channel of the rotary saw reaches 80A (the overcurrent threshold is 60A), it is determined to be an overcurrent fault. The fault monitoring unit immediately sends a fault alarm signal to the core control module. The core control module issues an on-site alarm through the audible and visual alarm, and at the same time sends fault information to the centralized control system and remote control terminal through the communication module, including fault type, fault location, fault occurrence time, and real-time fault parameters. 4.3 Rapid Fault Handling: After receiving an overcurrent fault alarm signal, the core control module sends a command to the multi-channel power supply output unit within 100ms to cut off the electronic switch of the power supply channel corresponding to the rotary saw. At the same time, it sends a power adjustment command to the power supply module to reduce the power supply of that channel to zero, thus preventing the fault from escalating. If the fault is in the low-voltage power supply submodule, the core control module will automatically cut off the power supply channel of the faulty submodule, and the other normal submodules will continue to provide low-voltage power supply to achieve uninterrupted operation. 4.4 Fault Recording and Source Tracing: The storage unit of the core control module synchronously records the entire fault process data, including the operating parameters 10 seconds before the fault occurs, the real-time parameters at the time of the fault, the fault handling measures and results. The stored data can be exported via USB wired connection or Bluetooth wireless method. Maintenance personnel can use the fault data to trace the fault source and repair the equipment, while also providing data support for subsequent power allocation strategy optimization.

[0030] 5. Emergency power supply management in case of emergencies 5.1 Emergency Handling of Main Power Supply Interruption: When the industrial-grade AC power supply of the hydropower station is suddenly interrupted, the voltage detection sensor of the power supply module detects that the supply voltage is 0 within 50ms and immediately sends a main power supply interruption signal to the core control module. After receiving the signal, the backup power switching module of the emergency control unit completes the main and backup power switching within 200ms, and electrically connects the portable backup power supply (24V / 100Ah lithium battery pack) with the separate power supply module and the emergency communication module to provide low-voltage power supply for the centralized control system, sensor module and emergency communication module, ensuring the basic control function and emergency communication function of the equipment. The backup power supply can provide power for no less than 8 hours, leaving sufficient time for on-site emergency handling by the staff. 5.2 Emergency Power Cut-off in Emergency Situations: When the slag removal equipment experiences jamming, malfunction of the execution unit, or other emergency situations, the staff can send an emergency power cut-off command through the remote control terminal, or the on-site staff can press the equipment's emergency stop button. Upon receiving the command, the emergency power cut-off module of the emergency control unit will quickly cut off the electronic switches of all power supply channels within 50ms, stopping the power output of the entire system and ensuring the safety of on-site personnel and equipment. If it is a local unit failure, a targeted emergency power cut-off command can be sent through the remote control terminal to cut off only the power supply channel corresponding to the faulty unit, while the other normal units can continue to operate. 5.3 Emergency Handling of Communication Failures: When the main communication module (4G+LORA) of the core control module fails and cannot communicate with the centralized control system and remote control terminal, the independent emergency communication module of the emergency control unit will automatically start and establish a LORA wireless communication link with the remote control terminal within 1 second, so as to realize the transmission of instructions and feedback of operation status in emergency situations. The communication distance is not less than 1km, which meets the communication needs of hydropower station dam operation.

[0031] 6. System routine maintenance and module replacement 6.1 Daily Operation Data Collection: The core control module continuously records the daily operation parameters of the system, including the working time of each module, power distribution records, number of faults, and operating status of each power supply channel. The data storage period is no less than 1 year. Staff can obtain the operation data through remote control terminal or on-site export and perform preventive maintenance on the system based on the data. 6.2 Power Module Maintenance and Replacement: The pluggable low-voltage power sub-modules of the separate power module adopt a snap-on quick-installation structure. When a sub-module has low power, malfunctions, or requires regular maintenance, the staff does not need to disconnect the power to the entire system. They can directly open the module access door of the protective shell to hot-swap the faulty sub-module for replacement. The replacement process takes no more than 2 minutes. The energy storage sub-module and rectifier unit of the power module have reserved independent access ports and can be disassembled and maintained separately without disassembling the entire system. 6.3 System Debugging and Optimization: Staff can fine-tune the parameters of the power dispatching algorithm module of the core control module through a remote control terminal. Based on the different seasons of slag removal operations at the hydropower station (such as large amounts of slag during the flood season and small amounts of slag during the dry season), the power allocation strategy can be optimized to improve the energy-saving and consumption-reducing effect and operational adaptability of the system. At the same time, power supply channels can be added or removed according to the upgrade and transformation of slag removal equipment to achieve synchronous adaptation between the system and the equipment.

[0032] The embodiments described above are merely illustrative of specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
