Specific embodiments

[0023] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as Figures 1-7As shown in the figure, the noise detector for multi-point noise detection in this embodiment includes a detector body 1. Two inlets and outlets 2 are provided on both sides of the detector body 1. Two circular plates 3 are connected to both sides of the lower part of the inner cavity of the detector body 1. A rotating shaft 4 is rotatably connected to the middle of the front end of the circular plate 3. A storage roller 6 is sleeved outside the rotating shaft 4. A signal line 23 is wound and connected to the outside of the storage roller 6. One end of the signal line 23 extends into the inlet and outlet 2 and the extended end is connected to a noise detection probe 7. The setting of multiple noise detection probes 7 can detect the noise at multiple points; A rotating rod 14 is rotatably connected to the upper part of the back of the detector body 1. A rotating plate 13 is sleeved outside the rotating rod 14. Second chutes 15 for limiting are provided at the front ends of the rotating plate 13 on both sides of the rotating rod 14 to prevent the second slider 18 from rotating during the moving process; A threaded rod 16 is rotatably connected inside the rotating plate 13. Opposite threads are provided on both sides of the threaded rod 16. The rotation of the threaded rod 16 can drive the two second sliders 18 to move in opposite or relative directions; One end of the threaded rod 16 extends outside the rotating plate 13 and the extended end is connected to a handwheel 17; Second sliders 18 are sleeved outside the threaded rod 16 inside the second chute 15. The second sliders 18 penetrate through the second chute 15 and extend outside the rotating plate 13, and the extended ends are connected to clamping plates 22; When it is necessary to fix the detector body 1 on a crossbar, first take out the first bolt 20 so that the rotating plate 13 can rotate. Rotate the rotating plate 13 to a vertical state and insert the first bolt 20 into the extension plate 19 and the inside of the detector body 1 to fix the rotating plate 13 on the back of the detector body 1. Then make the rotating plate 13 contact with the crossbar, and the crossbar is located between the two clamping plates 22; Rotate the handwheel 17 to drive the threaded rod 16 to rotate. The threaded rod 16 drives the two clamping plates 22 to move towards the crossbar until the two clamping plates 22 clamp the crossbar, so that the detector body 1 is installed on the crossbar; When it is necessary to fix the detector body 1 on a vertical rod, rotate the rotating plate 13 to a horizontal state, which is convenient for fixing and installing the detector body 1, and has high stability after installation.

[0025] Specifically, one end of the rotating shaft 4 extends outside the detector body 1. A handle 5 is provided on one side surface of the extended end of the rotating shaft 4. The rotating shaft 4 is driven by the handle 5 and then the storage roller 6 is driven to rotate. Rotating the storage roller 6 can receive the signal line 23 and the noise detection probe 7 into the detector body 1.

[0026] Further, first chutes 8 are formed at both the upper and lower ends of the inlet / outlet 2. A first slider 9 is slidably connected inside the first chute 8. One end of the first slider 9 penetrates through the first chute 8 and extends into the inlet / outlet 2. The extended end of the first slider 9 is connected to the noise detection probe 7, making the movement of the noise detection probe 7 inside the inlet / outlet 2 more stable. A spring 10 is arranged inside the first chute 8. One end of the spring 10 contacts one side surface of the first slider 9, and the other end of the spring 10 abuts against the side wall of the first chute 8. Since the noise detection probe 7 is completely received in the inlet / outlet 2 and cannot be directly taken out of the inlet / outlet 2 by hand, the noise detection probe 7 is ejected from the inside of the inlet / outlet 2 to the outside of the detector body 1 by the rebound of the spring 10. Second bolts 21 are threadedly connected inside the detector body 1 at both the upper and lower ends of the noise detection probe 7. One end of the second bolt 21 extends into the first slider 9, and the first slider 9 is fixed inside the first chute 8 through the second bolt 21. Two slots 24 are formed at both side edges of the front end of the detector body 1. A plug board 11 is inserted into the slot 24. A pull ring 12 is arranged at the front end of the plug board 11. By inserting the plug board 11 into the slot 24, the noise detection probe 7 is protected.

[0027] Furthermore, an extension plate 19 is connected to the middle of the rotating plate 13. A first bolt 20 is threadedly connected inside the extension plate 19. One end of the first bolt 20 extends into the detector body 1. By inserting the first bolt 20 into the extension plate 19 and the inside of the detector body 1, the rotating plate 13 is fixed to the back of the detector body 1.

[0028] The usage method of this embodiment is as follows: When the electrical components appearing in this application are in use, they are externally connected to a power source and are configured with corresponding controllers for use. When it is necessary to fix the detector body 1 on the cross bar, first take out the first bolt 20 so that the rotating plate 13 can rotate. Rotate the rotating plate 13 to a vertical state and insert the first bolt 20 into the extension plate 19 and the inside of the detector body 1 to fix the rotating plate 13 on the back of the detector body 1. Then make the rotating plate 13 contact with the cross bar, and the cross bar is located between the two clamping plates 22. Rotate the hand wheel 17 to drive the threaded rod 16 to rotate, and the threaded rod 16 drives the two clamping plates 22 to move towards the cross bar until the two clamping plates 22 clamp the cross bar, so that the detector body 1 is installed on the cross bar. When it is necessary to fix the detector body 1 on the vertical rod, rotate the rotating plate 13 to a horizontal state, which is convenient for fixing and installing the detector body 1, and is easy to fix and install the detector body 1, and has high stability after installation. When detecting the noise at multiple points, take out the insertion plate 11 from the inside of the slot 24 through the pull ring 12, so that the pressure of the insertion plate 11 on the noise detection probe 7 disappears. The spring 10 rebounds and pops the noise detection probe 7 from the inside of the inlet and outlet 2 to the outside of the detector body 1. Then pull the multiple noise detection probes 7 to different detection positions for detection, so that the noise at multiple points can be detected. When the noise detection is completed, drive the storage roller 6 to rotate through the handle 5 to receive the signal line 23 and the noise detection probe 7 into the detector body 1. Then insert the second bolt 21 into the detector body 1 and the inside of the first slider 9 to fix the first slider 9 inside the first chute 8. Then insert the insertion plate 11 into the inside of the slot 24.
