Description

Technical Field

[0001] This utility model relates to the field of power equipment testing technology, and in particular to an on-site testing device for SF6 and O2 monitoring sensors. Background Technology

[0002] In fields such as power systems and industrial equipment, SF6 and O2 monitoring sensors are widely used to monitor the concentration of SF6 gas (SF6 is used as an insulating and arc-quenching medium, and abnormal concentrations may indicate equipment leaks or malfunctions) and O2 concentrations inside equipment in real time (to ensure a safe working environment and avoid the risk of oxygen deficiency). The detection accuracy of the sensors is directly related to the safety and reliability of equipment operation, so they need to be regularly inspected and calibrated on-site.

[0003] However, there are currently many problems with the on-site inspection of SF6 and O2 monitoring sensors: First, there is a lack of dedicated on-site inspection equipment, resulting in unstable sensor positioning during inspection. External forces or operational shaking can easily cause misalignment between the inspection element and the sensor, affecting inspection accuracy. Second, the inspection operation relies on manual handling of the inspection element and sensor, which is cumbersome and inefficient, especially in batch inspections. Third, different models or different detection parameters (SF6 concentration, O2 concentration) of sensors require different inspection elements, and existing tools are difficult to quickly replace and adapt, resulting in poor versatility. Fourth, during on-site inspection, the sensors to be inspected lack a standardized placement and management structure, which can easily lead to confusion or collisions, affecting the orderliness of the inspection. Fifth, the movement of the inspection mechanism lacks stable guidance, resulting in poor consistency between the inspection element and the sensor, and large repeated inspection errors.

[0004] Therefore, we propose an on-site testing device for SF6 and O2 monitoring sensors. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an on-site inspection device for SF6 and O2 monitoring sensors, including a workbench and a fixed plate disposed on the workbench; it also includes an actuator for performing inspection actions on the SF6 and O2 monitoring sensors, the actuator including a sliding seat, a sliding sleeve, a connecting rod and a mounting plate mounted on the connecting rod, the mounting plate being used to mount inspection components, the sliding of the sliding seat driving the sliding sleeve, the connecting rod and the mounting plate to move, thereby realizing the inspection operation of the sensor.

[0007] Preferably, the fixing plate is provided with a mounting plate and a fixing column, and the fixing column is used to guide and support the sliding movement of the sliding seat.

[0008] Preferably, the workbench is provided with a placement box for placing the sensor to be inspected, and a stop body is provided next to the placement box. The stop body is used to position and stop the sensor during the inspection process.

[0009] Preferably, the actuator further includes a pull rod connected to the sliding seat, and the sliding seat is driven to slide by pulling the pull rod.

[0010] Preferably, the workbench is provided with a collar and a pressure plate. The collar is used to limit the position of the fixed column, and the pressure plate is used to press and position the sensor or inspection component.

[0011] Preferably, the mounting plate is replaceably equipped with a testing element for detecting SF6 concentration and O2 concentration. The movement of the actuator causes the testing element to contact or cooperate with the sensor to complete the on-site testing of the sensor.

[0012] The beneficial effects of this utility model are:

[0013] By cooperating with the workbench, fixed plate, and actuator including sliding seat, sliding sleeve, connecting rod, and mounting plate, the on-site inspection of SF6 and O2 monitoring sensors can be efficiently realized. The mounting plate and fixed column on the fixed plate cooperate with the collar and pressure plate on the workbench to stably guide and hold the sliding seat and sensor components, ensuring structural stability and inspection accuracy during the inspection process. The placement box on the workbench facilitates the centralized placement of sensors to be inspected, the abutment body can accurately position the sensor during inspection, and the pull rod makes the driving operation of the sliding seat more convenient. At the same time, the mounting plate can be replaced with different inspection elements, which can flexibly adapt to various inspection needs such as SF6 concentration and O2 concentration. The overall device is easy to operate, accurate in positioning, and highly applicable, effectively improving the efficiency and reliability of on-site inspection of SF6 and O2 monitoring sensors.

[0022] Example

[0023] Reference Figures 1-3 This is the first embodiment of the present invention, which provides an on-site testing device for SF6 and O2 monitoring sensors.

[0024] Specifically, to solve the above-mentioned technical problems, this utility model provides the following technical solution: an on-site inspection device for SF6 and O2 monitoring sensors, including a workbench 1 and a fixed plate 2 disposed on the workbench 1; it also includes an execution mechanism for performing inspection actions on SF6 and O2 monitoring sensors, the execution mechanism including a sliding seat 7, a sliding sleeve 8, a connecting rod 9 and a mounting plate 10 mounted on the connecting rod 9, the mounting plate 10 being used to mount inspection components, the sliding of the sliding seat 7 driving the sliding sleeve 8, the connecting rod 9 and the mounting plate 10 to move, thereby realizing the inspection operation of the sensor.

[0025] Furthermore, the fixing plate 2 is provided with a mounting plate 3 and a fixing column 4, the fixing column 4 being used to guide and support the sliding movement of the sliding seat 7.

[0026] Furthermore, the workbench 1 is provided with a placement box 13 for placing the sensor to be inspected, and a stop body 12 is provided next to the placement box 13. The stop body 12 is used to position and stop the sensor during the inspection process.

[0027] Furthermore, the actuator also includes a pull rod 11, which is connected to the sliding seat 7, and the sliding seat 7 is driven to slide by pulling the pull rod 11.

[0028] Furthermore, the workbench 1 is provided with a collar 5 and a pressure plate 6. The collar 5 is used to limit the position of the fixed column 4, and the pressure plate 6 is used to press and position the sensor or inspection component.

[0029] Furthermore, the mounting plate 10 is replaceably equipped with a test element for detecting SF6 concentration and O2 concentration. The movement of the actuator causes the test element to contact or cooperate with the sensor to complete the on-site inspection of the sensor.

[0030] In use, the SF6 and O2 monitoring sensors to be tested are placed in the placement box 13 of the workbench 1. When testing is required, the sensors are taken out, positioned by the abutment body 12, and held and fixed by the pressure plate 6 to ensure that the sensor is stable in position during the testing process. At the same time, SF6 concentration or O2 concentration testing elements matching the testing requirements are installed on the mounting plate 10 (if the testing type needs to be changed, the testing elements on the mounting plate can be directly replaced). During the inspection operation, pulling the lever 11 drives the sliding seat 7 to slide along the fixed post 4 on the fixed plate 2 (the fixed post 4 is positioned by the collar 5 to ensure guiding stability). The sliding of the sliding seat 7 causes the sliding sleeve 8 and the connecting rod 9 to move synchronously, thereby bringing the mounting plate 10 and its inspection element closer to and in contact with or cooperate with the sensor to be inspected. The interaction between the inspection element and the sensor completes the on-site inspection of the SF6 and O2 monitoring sensors. Throughout the process, the fixed post 4 guides and supports the sliding of the sliding seat 7, ensuring the cooperation accuracy between the inspection element and the sensor and improving the reliability of the inspection.
