Description

Technical Field

[0001] This utility model relates to the field of thermal power unit monitoring technology, specifically to an integrated device for dynamic monitoring of thermal power units. Background Technology

[0002] During operation, thermal power units require real-time and dynamic monitoring of key electrical parameters to ensure safe, stable, and efficient operation. Current is one of the most important monitoring parameters. Currently, when monitoring the conductor current of thermal power units, fixed ammeters or temporary measurements are usually taken using clamp-on ammeters.

[0003] While fixed ammeters can achieve continuous monitoring, their installation and removal are cumbersome, requiring tools and wiring operations, making it inconvenient to quickly move, calibrate, or replace monitoring equipment. On the other hand, while portable devices such as clamp meters are flexible, their measurement accuracy and long-term monitoring stability often fail to meet the high demands of industrial sites, and they cannot achieve fixed integration with the system for continuous monitoring. Furthermore, in the high-vibration operating environment of thermal power units, traditional terminals or clamps are prone to loosening due to vibration, leading to poor contact, affecting the accuracy of monitoring data, and potentially even causing safety accidents.

[0004] In response, we propose an integrated dynamic monitoring device for thermal power units. Utility Model Content

[0027] Example 1

[0028] Please see Figure 1-4One embodiment of this utility model includes an ammeter 200 and a wire end 300. The ammeter 200 is used to detect the current in the conductor of a thermal power unit. The ammeter 200 is provided with a quick-release assembly, which is used to quickly connect or disconnect the ammeter 200 from the wire end 300.

[0029] The wire end 300 is connected to the ammeter 200 via a quick-release assembly to monitor the thermal power unit.

[0030] Furthermore, the ammeter 200 and the quick-release assembly are respectively provided with threaded hole one and threaded hole two, which are compatible with each other and are coaxially distributed during installation.

[0031] Furthermore, the quick-release assembly includes a mounting base 101, which is bolted to the ammeter 200. Three constraint blocks 1011 are fixedly mounted on the mounting base 101, and each constraint block 1011 is provided with a sliding groove. A radial linkage clamping mechanism 102 is slidably mounted on the mounting base 101, and a disc base 103 is also rotatably mounted on the mounting base 101.

[0032] The fixed base 101 is connected to the ammeter 200 by bolts. The arc-shaped edge of the constraint block 1011 constrains its disc base 103, so that the disc base 103 can only rotate. The radial linkage clamping mechanism 102 is used to clamp the wire end 300.

[0033] Furthermore, the radial linkage clamping mechanism 102 includes a slider 1021, which is located in the groove of the drive disk 1031. A connecting rod 1022 is fixedly provided on the outer periphery of the slider 1021, and a clamping cylinder 1023 is fixedly provided at the other end of the connecting rod 1022. A first driving pin 1024 is fixed and eccentrically provided on one side of the clamping cylinder 1023, and a second driving pin 1025 is fixed and eccentrically provided on the other side of the clamping cylinder 1023. A fixed shaft 1026 is fixedly provided on the other side of the second driving pin 1025.

[0034] Among them, the groove section on the constraint block 1011 is O-shaped, the slider 1021 can move in the groove of the drive disk 1031, the arc end of the clamping cylinder 1023 is used to clamp the wire end 300, and the eccentric fixing of the clamping cylinder 1023 with the first drive pin 1024 and the second drive pin 1025 can realize the change of clamping diameter.

[0035] Furthermore, the disc base 103 is pin-connected to the fixed shaft 1026. The disc base 103 is provided with a connecting seat 1032, and a drive disc 1031 is fixedly provided on the connecting seat 1032. A through groove is provided on the drive disc 1031, and an operating handle 1033 is rotatably provided on the connecting seat 1032.

[0036] The drive disk 1031 has a through slot through which the first drive pin 1024 passes. Rotating the operating handle 1033 can drive the drive disk 1031 to rotate. The drive disk 1031 drives the clamping cylinder 1023 to rotate through the first drive pin 1024. Since the fixed shaft 1026 is fixedly connected to the second drive pin 1025, and the second drive pin 1025 is eccentrically and fixedly connected to the clamping cylinder 1023, the radial linkage clamping mechanism 102 can only move along the slide groove. Therefore, the rotation of the clamping cylinder 1023 drives the second drive pin 1025 and the clamping cylinder 1023 to rotate, and the clamping diameter formed by the arc end of the clamping cylinder 1023 changes with the swing angle.

[0037] The disc base 103 rotates, and the connecting rod 1022 swings toward the end of the wire 300, causing the arc end of the clamping cylinder 1023 to contract, reducing the clamping diameter and clamping the end of the wire 300.

[0038] The disc base 103 rotates in the opposite direction, and the connecting rod 1022 swings away from the wire end 300, causing the arc end of the clamping cylinder 1023 to expand, increasing the clamping diameter, and releasing the wire end 300.

[0039] Furthermore, the disc base 103 is also provided with a positioning mechanism, which includes a positioning pin 104. The operating handle 1033 has a hole, and the positioning pin 104 is located in the hole. The disc base 103 is provided with a corresponding blind groove 1041.

[0040] Among them, there are at least two blind slots 1041, and several blind slots 1041 are evenly distributed around the circumference of the disc base 103.

[0041] Specifically, after clamping the wire end 300, the positioning pin 104 is passed through the hole on the operating handle 1033 and inserted into the corresponding blind groove 1041 on the disc base 103 to position the operating handle 1033.

[0042] In summary, by rotating the operating handle 1033, the drive disk 1031 is rotated, which in turn drives the clamping cylinder 1023 to rotate together via the first drive pin 1024. The fixed shaft 1026 and the disk base 103 rotate together. Since the slider 1021 is constrained in the groove of the drive disk 1031, the rotation of the radial linkage clamping mechanism 102 is converted into radial linear motion along the groove, thereby driving the three clamping cylinders 1023 to move radially synchronously via the connecting rod 1022, realizing the change of clamping diameter to clamp or release the wire end 300. In addition, by locking the operating handle 1033 through the cooperation of the positioning pin 104 and the blind groove 1041, the clamping state can be reliably locked to prevent loosening in a vibration environment.
