Abstract
Description
Technical Field
[0001] This utility model relates to the field of equipment monitoring technology, specifically to an electrical equipment condition monitoring device. Background Art
[0002] An electrical equipment condition monitoring device is a system used to monitor and evaluate the operating status of electrical equipment in real time. It collects various physical parameters of the equipment during operation through sensors (such as temperature sensors, vibration sensors, and current transformers) installed on the equipment, and determines whether the equipment is operating normally through data processing and analysis. For example, temperature sensors and partial discharge sensors are installed inside the electrical cabinet to monitor the transformer's oil temperature, winding temperature, and partial discharge status in real time. When an abnormality is detected (such as excessively high temperature or increased partial discharge), the system will issue an alarm to remind maintenance personnel to handle the situation promptly.
[0003] Existing monitoring devices, when installed inside electrical cabinets, can only be adjusted vertically and horizontally from the inner wall of the cabinet, without being able to adjust the depth of the monitoring device. Therefore, the distance to the measured component cannot be easily controlled, affecting monitoring accuracy and sensitivity. To address this, we propose an electrical equipment condition monitoring device. Utility Model Content

[0021] Please see Figure 1 one Figure 5 The diagram shows an electrical equipment condition monitoring device, including a rectangular shell 1. A bidirectional lead screw 14 is rotatably connected to the middle of one inner side wall of the rectangular shell 1. The bidirectional lead screw 14 movably passes through the other inner side wall of the rectangular shell 1. A handwheel 7 is fixedly connected to one end of the bidirectional lead screw 14 located on the outside of the rectangular shell 1. U-shaped blocks 15 are symmetrically threaded on the outer wall of the bidirectional lead screw 14. Both U-shaped blocks 15 are slidably disposed in the inner front wall of the rectangular shell 1. Concave blocks 10 are fixedly connected to the front ends of both U-shaped blocks 15. Connecting rods 9 are rotatably connected between the upper and lower inner ends of the two concave blocks 10. The ends of the two connecting rods 9 away from the concave blocks 10 are rotatably connected to the monitor body 8. Concave plates 4 are symmetrically attached to the upper and lower ends of the rectangular shell 1. Guide mechanisms and locking mechanisms are provided between the two concave plates 4 and the rectangular shell 1, respectively. Mounting parts are provided at the rear two edges of the two concave plates 4.
[0022] Please see Figure 1 and Figure 4 In the figure, rectangular grooves 2 are provided through the front end of the rectangular shell 1 at the two U-shaped blocks 15 respectively, and the two rectangular grooves 2 slide with the two U-shaped blocks 15 respectively.
[0023] Please see Figure 1 , Figure 4 and Figure 5The guide mechanism shown in the figure includes a T-shaped groove 3 and a T-shaped block 18. The T-shaped block 18 is fixedly connected to the middle of the wall of the concave plate 4 corresponding to the rectangular shell 1. The T-shaped groove 3 is opened on the outer wall of the rectangular shell 1 corresponding to the T-shaped block 18, and the T-shaped groove 3 and the T-shaped block 18 are in sliding fit.
[0024] Please see Figure 2 and Figure 5 The locking mechanism shown in the figure includes two screw holes 12 and two screw holes 19. The two screw holes 12 are symmetrically opened through the upper front edge of the concave plate 4, and the two screw holes 19 are symmetrically opened through the upper rear edge of the concave plate 4. The two screw holes 19 correspond to the front and rear positions of the two screw holes 12 respectively, and the inner walls of the two screw holes 19 are screwed with knob screws 11. The two knob screws 11 are inserted into and screwed into the inner wall of the rectangular shell 1.
[0025] Please see Figure 1 , Figure 2 and Figure 5 The mounting components shown in the figure include four mounting plates 6, which are fixedly connected to the rear side edges of the two concave plates 4, and each of the four mounting plates 6 has a mounting hole 13 through it at its front end.
[0026] Please see Figure 3 In the figure, a rubber ring 16 is fixedly connected to the middle of the side wall of the rectangular shell 1. The inner wall of the rubber ring 16 is tightly fitted with the outer wall of the double-acting screw 14. Specifically, relying on the friction between the rubber ring 16 and the double-acting screw 14, the double-acting screw 14 can maintain a certain fixed state after rotation.
[0027] Please see Figure 1 and Figure 3 As shown in the figure, telescopic rods 5 are fixedly connected to the four rear corners of the monitor body 8 and the front end of the rectangular shell 1; specifically, the telescopic rods 5 make the connection between the monitor body 8 and the rectangular shell 1 more stable.
[0028] Please see Figure 3 In the diagram, multiple magnets 17 are embedded in a linear array at the rear end of the rectangular shell 1.
[0029] Working principle: This monitoring device can be directly attached to the electrical cabinet by multiple magnets 17 on the rectangular shell 1, or it can be installed in the electrical cabinet by mounting plate 6 and mounting holes 13 on the mounting plate 6 with bolts.
[0030] To ensure monitoring accuracy and sensitivity by bringing the monitor body 8 close to the device under test, a handwheel 7 can be rotated. The handwheel 7 will drive the bidirectional lead screw 14 to rotate on the rectangular shell 1. The bidirectional lead screw 14 will drive two U-shaped blocks 15 to slide closer to each other on the outer wall of the bidirectional lead screw 14 (during this process, the two U-shaped blocks 15 will also slide closer to each other on the rectangular grooves 2 on their respective rectangular shells 1). The two U-shaped blocks 15 will drive their respective concave blocks 10 to slide closer to each other on the rectangular shell 1. The two concave blocks 10 will drive the rear ends of their respective connecting rods 9 to move closer to each other (during this process, the two connecting rods 9 will also rotate on their respective concave blocks 10). Then the front ends of the two connecting rods 9 will move forward together and drive the monitor body 8 forward (during this process, both connecting rods 9 will rotate on the monitor body 8, and the four telescopic rods 5 between the monitor body 8 and the rectangular shell 1 will be stretched). The handwheel 7 can be stopped when the monitor body 8 moves to the appropriate position.
[0031] When it is necessary to bring the monitor body 8 closer to the component under test, before installation, first turn the two upper knob screws 11 upward in sequence. The two knob screws 11 will rotate upward in the screw holes 19 on their respective concave plates 4, and both knob screws 11 will rotate upward in the upper inner wall of the rectangular shell 1 until both knob screws 11 are completely turned away from their respective screw holes 19. Then pull the upper concave plate 4 backward. The concave plate 4 will slide backward at the upper end of the rectangular shell 1. During this process, the T-shaped block 1 on the concave plate 4... 8 will slide backward in the upper T-shaped groove 3 on the rectangular shell 1 until the rear end of the T-shaped block 18 is in contact with the inner rear end of the T-shaped groove 3. Then, insert and tighten the two knob screws 11 into the two screw holes 12 on the concave plate 4. At this time, the two knob screws 11 will also be inserted and tightened into the upper inner wall of the rectangular shell 1. Then the concave plate 4 can be fixed again between itself and the rectangular shell 1 after it moves backward. Similarly, the same operation can be used to fix the lower concave plate 4 between itself and the rectangular shell 1 after it moves backward. The operation is simple.
[0032] It should be noted that when this monitoring device is installed in the electrical cabinet, the insertion depth of the monitoring body 8 can be adjusted according to the position of the monitored component, so that the distance between the monitoring body 8 and the measured component can be conveniently controlled, thereby helping to ensure monitoring accuracy and sensitivity.
