Description

Technical Field

[0001] This invention belongs to the field of power plant safety monitoring technology, specifically a multimodal sensing intelligent safety monitoring and early warning device for power plants. Background Technology

[0002] In today's era of continuously growing energy demand and increasingly critical energy supply stability, power plants, as core facilities for energy supply, are like the "heart" of the energy network. Their safe and stable operation directly affects the normal operation of the entire energy system and the stable development of society. Once a power plant malfunctions, it will not only lead to energy supply interruptions, affecting residents' daily lives, industrial production, and commercial activities, but may also trigger a series of chain reactions, causing huge economic losses and social impacts. Therefore, ensuring the safe operation of power plants and achieving accurate and comprehensive monitoring of their operational status is of paramount importance to ensuring a stable energy supply.

[0003] However, the safety monitoring devices currently installed in power plants have many problems that urgently need to be solved, which seriously restrict the effectiveness and timeliness of power plant safety monitoring.

[0004] Most existing power plant safety monitoring devices are limited to monitoring a single physical quantity, such as measuring only temperature or vibration. This single-dimensional monitoring method is like "the blind men and the elephant," only able to obtain partial information about the power plant's operating status, and unable to comprehensively and deeply understand the actual operating conditions of the power plant equipment from multiple angles and levels.

[0005] Besides the problem of limited monitoring dimensions, existing monitoring devices also have significant shortcomings in terms of timely early warning. Due to the lack of comprehensive analysis and real-time processing capabilities for multi-dimensional data, monitoring devices often fail to issue early warning signals quickly and accurately when abnormal conditions occur in power plant equipment.

[0006] In some complex fault scenarios, abnormal changes in equipment may be gradual, with initial symptoms not being obvious, and monitoring data for a single physical quantity may still fluctuate within the normal range. Only when the fault develops to a certain extent and multiple physical quantities show abnormalities simultaneously can the monitoring device detect the problem. However, by this time, the fault may have already entered a relatively serious stage, leaving maintenance personnel with very limited time to handle it, and it may even be impossible to prevent an accident from occurring.

[0007] Furthermore, the early warning mechanisms of existing monitoring devices are mostly quite simple, typically just setting some fixed thresholds, and issuing an alarm when the monitored data exceeds the threshold. However, the operating status of power plant equipment is affected by a variety of factors, such as load changes and ambient temperature, and fixed thresholds are difficult to adapt to the actual needs under different operating conditions. This leads to situations where, even if the equipment is operating normally, false alarms may be triggered because the monitored data briefly exceeds the threshold; while in other situations, the equipment may have already experienced a serious malfunction, but because the monitored data has not yet reached the threshold, the early warning signal cannot be issued in time, thus delaying the opportunity to handle the fault.

[0008] Sensors in power plants are a crucial component of safety monitoring systems, and the ease of installation and maintenance directly impacts the efficiency and safety of monitoring efforts. Currently, power plant sensors are often deployed in high locations, such as on top of large equipment or high-altitude pipelines. These locations typically present challenges due to limited space and inconvenient operation, significantly complicating sensor installation and maintenance.

[0009] Most existing sensors are installed using fixed bolts. While this method offers a degree of stability, maintenance requires the use of elevated equipment such as ladders and lifting platforms. Maintenance personnel must climb to higher positions to inspect, replace, or adjust the sensors, a cumbersome and time-consuming process. Each elevated operation requires significant time and effort for preparation, such as setting up the equipment and checking safety measures, which not only reduces maintenance efficiency but also increases costs.

[0010] In summary, existing power plant safety monitoring devices suffer from numerous problems in terms of monitoring dimensions, timely early warning, and sensor installation and maintenance. These issues seriously affect the safe operation of power plants and the stable supply of energy. Therefore, developing a new type of power plant safety monitoring device capable of multi-dimensional monitoring, timely early warning, and easy installation and maintenance has become a crucial issue that urgently needs to be addressed in the power plant industry.

A second limiting mechanism is provided at the lower end of the mounting rod and below the stop rod to limit the rotation of the stop rod relative to the crossbar.

[0013] Furthermore, the first limiting mechanism includes an L-shaped rod and a rotating ring. The rotating ring is rotatably disposed on the inner wall of the bottom end of the groove. The rotating ring is concentrically disposed with respect to the mounting ring. A plurality of L-shaped rods are arranged in a circular array around the center of the rotating ring and fixedly disposed on the outer wall of the rotating ring. A first insertion hole is provided on the side wall of the plurality of sliding rods near the center of the mounting ring. The ends of the plurality of L-shaped rods away from the rotating ring are inserted into the corresponding first insertion holes. A third limiting mechanism for restricting the rotation of the rotating ring is provided on one side of the bottom of the groove.

[0014] Furthermore, the pushing mechanism includes a push rod and a round pin. Two side plates are fixedly installed on one side of the lower surface of the mounting ring, and a connecting shaft is rotatably installed between the two side plates. The push rod is fixedly sleeved on the rod wall of the connecting shaft. A strip-shaped opening is opened on the side wall of the push rod. One end of the crossbar extends to the rear side of the push rod. The round pin is fixedly sleeved on the rod wall of the crossbar at a position corresponding to the strip-shaped opening, and the front end of the round pin passes through the strip-shaped opening.

[0015] Furthermore, the second limiting mechanism includes a stop block and a plug rod. A fixing shell is fixedly installed on the lower side wall of the mounting rod and below the stop rod. The stop block is slidably installed inside the fixing shell. The plug rod is fixedly installed on the upper side of the stop block. The upper end of the plug rod extends to the outer side of the fixing shell. A second insertion hole is opened at the lower end of the stop rod. The upper end of the plug rod is inserted into the second insertion hole.

[0016] Furthermore, a spring is fixedly installed on the lower side of the stop block, and the other end of the spring is fixedly connected to the inner wall of the fixed shell.

[0017] Furthermore, the third limiting mechanism includes a support plate and a threaded rod. The support plate is fixedly disposed at the bottom of the groove on one side.

Multiple sliding rods 4 are provided with a first insertion hole on the side wall of the end near the center of the mounting ring 3. The ends of multiple L-shaped rods 18 away from the rotating ring 17 are inserted into the corresponding first insertion hole. A third limiting mechanism for limiting the rotation of the rotating ring 17 is provided on the bottom of one side of the groove.

[0038] Please see Figure 1-4 The pushing mechanism includes a push rod 11 and a pin 12. Two side plates 9 are fixedly installed on one side of the lower surface of the mounting ring 3. A connecting shaft 10 is rotatably installed between the two side plates 9. The push rod 11 is fixedly sleeved on the rod wall of the connecting shaft 10. A strip-shaped opening is opened on the side wall of the push rod 11. One end of the crossbar 13 extends to the rear side of the push rod 11. The pin 12 is fixedly sleeved on the rod wall of the crossbar 13 and at a position corresponding to the strip-shaped opening. The front end of the pin 12 passes through the strip-shaped opening. An anti-detachment ring is fixedly sleeved on the end of the pin 12 away from the crossbar 13.

[0039] Please see Figure 1-4The second limiting mechanism includes a stop block 21 and a rod 23. A fixed housing 20 is fixedly installed on the lower side wall of the mounting rod 2 and below the stop rod 14. The stop block 21 is slidably installed inside the fixed housing 20. The rod 23 is fixedly installed on the upper side of the stop block 21. The upper end of the rod 23 extends to the outer side of the fixed housing 20. A second insertion hole is opened at the lower end of the stop rod 14. The upper end of the rod 23 is inserted into the second insertion hole.

When maintenance of the monitoring and early warning device is required, first rotate the threaded rod 15 to disengage it from the third insertion hole of the rotating ring 17, releasing the limit on the rotating ring 17. Then, rotate the rotating ring 17 to drive the L-shaped rod 18 to disengage from the first insertion hole of the slide rod 4, allowing the slide rod 4 and the corresponding monitoring and early warning device to be pulled out from the first through hole of the mounting ring 3, completing the disassembly of a single component. Pulling down the insertion rod 23 causes the stop block 21 to compress the spring 22, disengaging the insertion rod 23 from the second insertion hole of the stop rod 14. Rotating the stop rod 14 until it separates from the mounting rod 2 pushes the crossbar 13, causing the round pin 12 to slide within the slot of the push rod 11. The push rod 11 rotates around the connecting shaft 10 and pushes the mounting ring 3 down the mounting rod 2 to a lower position, facilitating centralized maintenance of all monitoring and early warning devices. After maintenance, the operation is reversed to reset and fix the device. The entire process requires no climbing equipment, saving time and effort. The anti-detachment ring prevents the round pin 12 from slipping, and the rectangular structure of the sliding rod 4 and the first through hole ensure installation stability.
