[0032] In order to make the purpose, technical scheme and advantages of the present invention clearer, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The embodiments described in this application are only embodiments of a part of the present invention, rather than all embodiments. Based on the spirit of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the present invention.

[0033] Embodiment 1:

[0034] like Figure 1 As shown, an embodiment of the present invention provides an intelligent maintenance-free respirator with a monitoring function, including a respirator body, on which an intelligent monitoring system is integrated, including: a monitoring module, a data processing unit 2, a cleaning module, a remote communication module and an alarm and feedback module.

[0035] Monitoring module: The monitoring module is a vital part of the respirator system. It cleverly integrates a variety of precision components, including high-precision pressure sensors 12, temperature and humidity sensors 13, and high-definition endoscopes, etc., to comprehensively and in real time monitor the internal environment of the respirator. The module can accurately capture and feedback key parameters such as pressure, temperature and humidity, as well as the oil pillow capsule viewing screen, and send it to the data processing unit so that it can quickly analyze whether there is a risk of blockage or changes in moisture absorption efficiency through intelligent algorithms, and provide timely warnings for equipment maintenance. It is particularly worth mentioning that the monitoring module also supports internal detection without power outages, and uses endoscope technology to visually check the integrity of the capsule inside the oil pillow, ensuring the safe and worry-free operation of the transformer and significantly improving maintenance efficiency and equipment reliability.

[0036] The data processing unit is connected to the monitoring module, the alarm and feedback module, and the cleaning module. It is used to determine whether the respirator body is blocked or over-pressurized and its moisture absorption efficiency based on the temperature, humidity, pressure data, and the oil pillow capsule viewing screen. The data processing unit is the core control center. Its algorithm framework can efficiently process data from various sensors and accurately identify fault signals. By using intelligent algorithms, the unit can not only quickly respond to common abnormal situations such as blockage and over-pressure, but also issue early warnings at the early stage of the abnormality, providing the operation and maintenance team with valuable response time.

[0037] Cleaning module: used to extract moisture and dust from the respirator body when the data processing unit 2 determines that the respirator body is blocked or over-pressurized or starts at a fixed time. The remote communication module is connected to the monitoring module and the alarm and feedback module, including: LoRa (Long Range Radio) module and LoRa module antenna 8. The LoRa module is set at the bottom of the data processing unit 2 and connected to the data processing unit and the alarm and feedback module; the LoRa module antenna is connected to the LoRa module. The remote communication module uses wireless communication technology to transmit monitoring data to the remote monitoring center in real time to realize remote monitoring and fault diagnosis.

[0038] The alarm and feedback module is connected to the data processing unit and the remote communication module. The alarm and feedback module is an important line of defense to ensure the stable operation of the system. Once the data processing unit identifies an abnormal condition through analysis, the mechanism will be activated immediately to trigger the alarm system quickly and accurately. On the one hand, through wireless communication technology, emergency information is transmitted to the remote monitoring center in real time to ensure that the backstage personnel can obtain and evaluate the abnormal situation in the first time; on the other hand, the on-site fault lights will also light up synchronously to warn the on-site maintenance personnel in an intuitive way. This two-pronged notification method not only ensures the uninterrupted transmission of information, but also greatly shortens the response time, providing a strong guarantee for timely decision-making and efficient disposal, thereby effectively maintaining the safe and stable operation of the system.

[0039] Furthermore, pressure monitoring: a reasonable pressure threshold range is set, and when the pressure is detected to be beyond the set range, it is determined to be a ventilator blockage or overpressure;

[0040] Breathing discrimination: The current airflow direction is determined by the positive and negative values ​​of the pressure value;

[0041] Temperature and humidity monitoring: The temperature and humidity sensor monitors the ambient temperature and humidity in real time to determine the drying effect; at the same time, a reasonable threshold is set to assist in determining the working status of the respirator;

[0042] Comprehensive judgment: Combine the monitoring results of multiple parameters such as pressure, temperature and humidity to conduct comprehensive analysis and judgment to improve monitoring accuracy;

[0043] Remote monitoring and fault diagnosis: The remote monitoring center receives monitoring data from the intelligent maintenance-free respirator and realizes remote monitoring and fault diagnosis through data analysis. When the respirator is found to be blocked or over-pressurized, the system automatically generates a fault report and notifies the operation and maintenance personnel. At the same time, the system supports parameter customization function, which can adjust the respirator parameters or startup thresholds as needed.

[0044] In a preferred but non-limiting embodiment of the present invention, the cleaning module includes: an air pump, which is arranged on the outside of the respirator body and connected to the air outlet of the respirator body through a pipeline. The air pump is used to extract moisture and dust inside the respirator body when the data processing unit determines that the respirator body is blocked or over-pressured or is started at a fixed time to unclog the respirator body, thereby achieving an automatic cleaning and maintenance effect and reducing the frequency of on-site maintenance.

[0045] The intelligent maintenance-free respirator of the present invention also has an intelligent maintenance function. When the system detects that the silica gel drying cylinder is saturated, the system automatically starts the heating device to regenerate the silica gel; when the pressure exceeds the critical value, the internal pressure can be automatically released. In addition, the system also has multiple modes such as cycle control and threshold control to achieve automatic regeneration and recycling of silica gel.

[0046] The respirator body adopts modular design, including connecting flange 4, filter 9, silica gel drying cylinder 10, heating device 11, outer cylinder and other components. The connecting flange 4 is used to connect with the oil storage cabinet of the transformer oil filling equipment; the filter 9 adopts a multi-layer filter structure to effectively remove dust, sand and other particles in the air; the silica gel drying cylinder 10 has a built-in high-efficiency silica gel desiccant to absorb moisture in the air; the heating device 11 is installed inside the silica gel drying cylinder 10 to heat and regenerate the silica gel; the outer cylinder plays the role of protecting the internal components, isolating the external environment and condensing condensed water.

[0047] Specifically, Figure 2-6 As shown, the respirator body includes a glass cylinder 1, a silica gel drying cylinder 10, a heating device 11, a filter 9 and a connecting flange 4. The silica gel drying cylinder 10 is fixed in the glass cylinder 1, the heating device 11 is fixed in the silica gel drying cylinder 10, the filter 9 is fixed at the bottom end of the glass cylinder 1, and the connecting flange 4 is fixed at the top end of the glass cylinder 1.

[0048] Furthermore, the glass tube 1 is provided with an air inlet at the top and an air outlet at the bottom. Solenoid valves are provided at the air inlet and the air outlet, and the air outlet is connected to an air pump through a pipeline.

[0049] Furthermore, an interface 3 is fixed at the top of the glass cylinder, and this end is the dry end of the respirator body. A connecting flange 4 is fixed at the top of the interface 3, and a temperature and humidity sensor 13 and a pressure sensor 12 are arranged in the interface 3. A release valve 5 is arranged on one side of the interface 3, and the release valve 5 is connected to the data processing unit 2, and is used to automatically open to release pressure when the data processing unit determines that the respirator body is over-pressured. The data processing unit 2 is fixed to one side of the glass cylinder 1, and a human-computer interaction display screen 6 is arranged on the surface of the data processing unit 2, a LoRa module antenna 8 is arranged at the bottom of the data processing unit 2, and an alarm indicator light 7 is arranged on the side of the data processing unit 2, and the alarm indicator light is connected to the data processing unit.

[0050] The heating device 11 is disposed inside the silica gel drying cylinder, and is used to heat, dry and regenerate the silica gel drying cylinder 11 inside the respirator body when the data processing unit 2 determines that the respirator body is blocked or over-pressured. The heating device 11 includes: a diffusion plate 1101 and a constant temperature heater 1102 fixed on the diffusion plate 1101, and a plurality of exhalation holes 1103 are opened on the diffusion plate 1101.

[0051] In a preferred but non-limiting embodiment of the present invention, more than or equal to one diffusion plate 1101 is arranged inside the silica gel drying cylinder 10; the two ends of each diffusion plate 1101 along the first direction are respectively fixedly connected to the two ends of the silica gel drying cylinder 10 along the first direction; the constant temperature heater 1102 is arranged on one side of the diffusion plate 1101 and is connected to the data processing unit 2; at least more than or equal to one exhalation hole 1103 is arranged on the diffusion plate 1101.

[0052] Furthermore, when the number of diffusion plates 1101 is greater than one, one side of each diffusion plate 1101 is connected to each other, and the other side is fixedly connected to the inner wall of the silica gel drying cylinder 10, and the diffusion plates 1101 are evenly arranged inside the silica gel drying cylinder 10 at equal intervals.

[0053] The intelligent monitoring module of the present invention is cleverly integrated inside the respirator body to ensure the accuracy and reliability of the measurement. The pressure sensor 12 is installed at a key position inside the respirator and can directly sense changes in the internal pressure; the temperature and humidity sensor 13 is installed at the dry end inside the respirator body to reflect changes in the actual working environment. These sensors are connected to the microprocessor through precise circuit design to achieve data collection, processing and analysis. The endoscope is installed inside the oil pillow located inside the silica gel drying cylinder, and is connected to the corresponding unit of the desiccant in the oil filling equipment through the breathing duct to ensure intuitive inspection of the internal conditions of the oil pillow.

[0054] As the core of the intelligent monitoring module, the data processing unit is responsible for receiving the raw data from each sensor and performing preprocessing, filtering and denoising, data fusion and other processing steps to improve the accuracy and reliability of the data. Subsequently, the processed data is analyzed using a preset algorithm to determine whether the respirator is blocked or over-pressurized. In order to improve the accuracy of the judgment, a variety of technical means such as threshold comparison are introduced into the algorithm to ensure the accuracy and timeliness of the monitoring results.

[0055] The remote communication module transmits the monitoring data processed by the intelligent monitoring module to the remote monitoring center in real time through the built-in wireless communication module (such as the LoRa module). In order to ensure the stability and security of data transmission, the communication module is configured in accordance with the communication protocol required by the State Grid. At the same time, in order to cope with abnormal situations such as communication interruption, the communication module also has automatic reconnection and data caching functions to ensure the integrity and continuity of the monitoring data.

[0056] The human-machine interactive display screen, as the core interactive interface of the respirator system, realizes accurate and instant visual display of key operating parameters. The screen refreshes the temperature and humidity values ​​in real time, allowing users to quickly and accurately grasp the environmental status inside the device. In addition, the display screen also presents detailed information on the working status of the device, including breathing direction, dynamic changes in internal pressure values, and real-time monitoring of cycle thresholds, providing comprehensive and professional equipment monitoring and management support for professionals, greatly improving the safety and efficiency of operations.

[0057] In summary, the intelligent maintenance-free respirator with monitoring function provided by the present invention integrates the intelligent monitoring module, remote communication module and intelligent maintenance function into one, thereby realizing automatic detection and immediate feedback of blockage or overpressure of the respirator of oil injection equipment such as transformers and reactors. The respirator not only improves the operating safety and maintenance efficiency of the equipment, but also reduces the operating cost and manpower investment. Therefore, the present invention has important application value and promotion prospects in the technical field of auxiliary devices for power equipment.

[0058] Embodiment 2:

[0060] During the operation of the equipment, the respirator body is connected to the oil storage cabinet of the oil filling equipment through the connecting flange to achieve gas exchange. The pressure sensor in the intelligent monitoring module monitors the pressure changes inside the respirator in real time and determines the gas flow conditions. The temperature and humidity sensor monitors the ambient temperature and humidity. When an abnormal pressure is detected (such as too high or too low pressure), it is judged that the respirator is blocked or over-pressurized. At this time, the intelligent monitoring module sends the abnormal information to the remote communication module and transmits it to the remote monitoring center through wireless communication technology.

[0061] Embodiment 3:

[0062] The embodiment of the present invention provides a monitoring method, using the intelligent maintenance-free respirator with monitoring function in embodiment 1, the monitoring method comprises the following steps:

[0063] The monitoring module collects the temperature, humidity, pressure data inside the respirator body and the oil pillow capsule viewing screen, and sends it to the data processing unit;

[0064] The data processing unit 2 receives the temperature, humidity, pressure data and the oil pillow capsule viewing screen to determine whether the respirator body is blocked or over-pressured and the moisture absorption efficiency; when the respirator body is blocked or over-pressured, the data processing unit 2 activates the alarm and feedback unit to sound an alarm, and at the same time activates the heating device 11 and the release valve through the data processing unit 2 to dry and regenerate the silica gel in the silica gel drying cylinder 10 and release the valve pressure;

[0065] The temperature and humidity, pressure data, oil pillow capsule viewing screen and alarm status obtained by the monitoring module are sent to the remote monitoring center through the remote communication module. The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.

[0066] The beneficial effect of the present invention lies in that, compared with the prior art, the intelligent maintenance-free respirator with monitoring function provided by the present invention integrates an intelligent monitoring module, a remote communication module and an intelligent maintenance function into one, thereby realizing automatic detection and immediate feedback of blockage or overpressure of the respirator body of oil injection equipment such as transformers and reactors, and can start the cleaning module when the data processing unit determines that the respirator body is blocked or overpressured or at a scheduled time, and extract moisture and dust inside the respirator body through the cleaning module to achieve the effect of automatic cleaning, thereby realizing the maintenance-free function, completely liberating manpower, and realizing unmanned supervision; the intelligent maintenance-free respirator with monitoring function provided by the present invention not only improves the operating safety and maintenance efficiency of the equipment, but also reduces the operating cost and manpower investment; therefore, the present invention has important application value and promotion prospects in the technical field of auxiliary devices of power equipment.

[0067] Furthermore, the data processing unit provided by the present invention analyzes the temperature, humidity and pressure values ​​inside the respirator bodies through a data processing algorithm, and accurately identifies the changing trend of the device status.

[0068] Furthermore, the present invention also sets a heating device inside the respirator body and sets a release valve at one end thereof. The release valve and the heating device are both connected to the data processing unit.

At the same time, the respirator also integrates the oil pillow internal visual inspection function. This forward-looking design changes the traditional power outage inspection mode.
