[0024] Figure 1 It is a system block diagram of the present invention. DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] See also Figure 1 As shown, a mining explosion-proof inverter with adaptive adjustment function, the system includes:

[0027] The electrical control unit is used to receive and process environmental data from the sensor module. It monitors multiple environmental parameters in the mine, such as temperature, humidity, gas concentration, vibration, etc., in real time to ensure that the mine explosion-proof inverter can make dynamic adjustments according to the actual working conditions of the mine.

[0028] The working principle is: the sensor module continuously collects environmental data in the mine and transmits this data to the electrical control unit. The control unit analyzes the data and determines whether the current environment exceeds the normal working range based on the preset algorithm and threshold. If the environment changes, the control unit will automatically adjust the output frequency and power of the inverter according to the analysis results to ensure that the equipment can operate stably and improve energy efficiency. At the same time, the control unit can also transmit the equipment status and environmental data to the monitoring center in real time through the remote communication module, which is convenient for the staff to conduct remote monitoring and adjustment, thereby further improving the safety and work efficiency of mine equipment.

[0029] The sensor module uses a variety of built-in sensors to monitor multiple key parameters in the mine environment, such as temperature, humidity, gas concentration and vibration in real time. Each sensor is responsible for collecting data on specific environmental indicators. The temperature sensor senses temperature changes in the mine, the humidity sensor detects air humidity, and the gas sensor monitors the concentration of possible harmful gases in real time. The vibration sensor is used to monitor the vibration of the mine structure. The data collected by the sensor will be converted into electrical signals in real time and preliminarily processed by the internal data processing module. The processed data will be transmitted to the electrical control unit via wired or wireless communication to ensure that the system can respond and adjust in time according to changes in the mine environment, thereby ensuring the stability and high-efficiency operation of the mining explosion-proof inverter.

[0030] The power regulation unit accurately adjusts the output power of the inverter according to the instructions of the electrical control unit to ensure that the equipment always maintains the best operating state under different mine environmental conditions. When the electrical control unit receives and analyzes the environmental data from the sensor module, if the environmental parameters exceed the normal range, the control unit will calculate the power value that needs to be adjusted and send instructions to the power regulation unit. After receiving the instructions, the power regulation unit adjusts the power output device inside the inverter to change the output frequency and voltage of the inverter to adapt to the new working environment.

[0031] This process ensures that the inverter maintains high-efficiency operation when the load or environment changes, while avoiding power waste or equipment overload, improving system stability and energy efficiency.

[0032] Explosion-proof housing to prevent explosive gases in the mine from coming into contact with the electrical components inside the drive;

[0033] The explosion-proof housing is made of high-strength, corrosion-resistant alloy materials to effectively prevent explosive gases from contacting the electrical components inside the inverter in a mine environment.

[0034] Its working principle is: the explosion-proof casing completely isolates the internal electrical components of the inverter from the external environment, preventing flammable and explosive gases that may exist in the mine from entering the inverter. When the external gas concentration reaches a certain level, the explosion-proof casing can withstand the electrical sparks or high temperatures that may be generated inside without explosion or fire, thus forming a solid safety barrier.

[0035] The communication module is responsible for bidirectionally exchanging the real-time data of the inverter with the remote monitoring system through wireless or wired communication to achieve remote control and monitoring. Its working principle is: the communication module regularly transmits various environmental data obtained by the electrical control unit and the sensor module to the remote monitoring system, so that the operator can understand the operating status and environmental conditions of the mine equipment in real time.

[0036] The electrical control unit achieves efficient management and precise control of the system through the coordinated work of the main controller and the auxiliary controller. The main controller is responsible for real-time processing of environmental data provided by the sensor module, data analysis and decision-making, and ensuring that the equipment makes corresponding adjustments according to changes in the mine environment;

[0037] The auxiliary controller accurately adjusts the output power and frequency of the inverter according to the instructions of the main controller to ensure that the equipment always maintains the best performance under different load and environmental conditions;

[0038] This structure effectively shares the respective functions, improves the system's response speed and processing capabilities, thereby enhancing the stability, efficiency and safety of the inverter, ensuring that the equipment in the mine environment can operate continuously, stably and safely.

[0039] The adaptive regulation function automatically adjusts the speed of ventilation equipment according to the changes in gas concentration in the mine, effectively improving the ventilation efficiency and safety of the mine. When the gas concentration reaches the set dangerous level, the system can respond quickly by adjusting the speed of ventilation equipment to enhance air circulation, reduce the concentration of harmful gases, and ensure the safety of the mine environment.

[0040] This function not only optimizes the operation of the ventilation system and avoids energy waste caused by excessive ventilation, but also responds to fluctuations in gas concentration in the mine in real time, ensures the safety of workers in the mine, reduces potential safety hazards, and improves the overall system's intelligence level and emergency handling capabilities.

[0041] The power regulation unit can dynamically adjust the output power and frequency through real-time monitoring and regulation of voltage and current through a digital signal processor (DSP), ensuring that the system can flexibly adapt to changes in electrical load.

[0042] The regulation function effectively improves the response speed and stability of the inverter, avoids power instability caused by load fluctuations, optimizes energy efficiency and reduces energy consumption. Through the efficient processing capability of DSP, the system can accurately adjust power output according to actual needs and maintain the best working state of the equipment, thereby improving the performance, reliability and economy of the overall equipment.

[0043] The explosion-proof casing is made of high-strength alloy material, and heat dissipation holes are set on the surface of the casing to ensure the safety and stability of the equipment in harsh environments. The high-strength alloy material effectively resists external impact and corrosion, enhances the explosion-proof performance of the equipment, and ensures the safe operation of the equipment in high-risk areas. The design of the heat dissipation holes helps to improve the heat dissipation efficiency of the equipment, prevent overheating, extend the service life of the equipment and maintain its optimal working condition, ensuring efficient operation in complex environments.

[0044] The sensor module integrates temperature sensors, humidity sensors, gas sensors and vibration sensors, which can comprehensively monitor various key parameters of equipment and environment. Temperature and humidity sensors ensure that environmental conditions are suitable to avoid equipment failure due to environmental changes; gas sensors detect the concentration of harmful gases in real time to improve safety; vibration sensors can detect equipment abnormalities in time to prevent potential mechanical failures;

[0045] Through the joint work of multiple sensors, the system can obtain real-time information on the status of the environment and equipment, provide early warnings and make adjustments, thereby improving the stability, safety and operating efficiency of the equipment.

[0046] The communication module supports both wireless and wired communication to achieve real-time data exchange and remote control with the remote monitoring center. Wireless communication provides flexibility and wide coverage, and is suitable for places where wiring is not possible, while wired communication ensures the stability and reliability of data transmission.

[0047] The dual communication method ensures that the system can operate stably in different environments, so that the equipment status and working data can be transmitted to the remote monitoring center in real time, facilitating remote monitoring, fault diagnosis and equipment control, and improving the intelligent management and maintenance efficiency of the system.

[0048] The cooling system adopts a combination of closed water cooling and air cooling to ensure the temperature control effect of the equipment during long-term operation. The closed water cooling system can efficiently take away the heat inside the equipment, avoid water evaporation, improve cooling efficiency and reduce water waste; the air cooling system quickly dissipates heat through air circulation, which is suitable for places with small loads and large changes in ambient temperature;

[0049] The complementary design of the two cooling methods not only improves the heat dissipation capacity of the equipment, but also ensures stability and reliability in various working environments, prolongs the service life of the equipment and improves the overall performance of the system.

[0050] The electrical control unit includes a power management module, which can maintain the stable operation of the system by adjusting the power output when the mine power supply conditions are unstable. This module effectively responds to problems such as voltage fluctuations and power shortages, ensures that the equipment continues to work normally, avoids failures or downtime caused by unstable power, and improves the reliability and safety of the system;

[0051] By intelligently adjusting power output, the power management module not only ensures the efficient operation of the equipment, but also effectively extends the service life of the equipment and reduces maintenance and operating costs.

[0052] The inverter has a fault self-diagnosis function, which can automatically identify equipment faults and send warnings to operators through the communication module. This function improves the automation and intelligence level of the system, allowing faults to be discovered and handled in a timely manner, avoiding downtime and damage caused by equipment problems:

[0053] Through real-time monitoring and alarms, operators can take prompt countermeasures to reduce maintenance time and downtime losses, thereby improving system reliability and operating efficiency.
