Description

Technical Field

[0001] This invention relates to the field of sound detection technology, and in particular to a sound detection device for transformer monitoring. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are a primary coil, a secondary coil, and an iron core (magnetic core). The main functions of a transformer include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization (magnetic saturation transformer). According to their application, they can be divided into power transformers and special transformers. Transformers are fundamental equipment for power transmission and distribution, and are widely used in industry, agriculture, transportation, urban communities, and other fields.

[0003] Currently, when transformers are used in power stations, multiple transformers are usually placed together. However, when monitoring transformers, current, transformer alarms, and various sounds need to be monitored. The existing monitoring methods mostly involve installing one detection device for each transformer, which requires setting up multiple sensing platforms for real-time monitoring in the background, resulting in increased costs. Furthermore, it is inconvenient to change the monitoring location during monitoring, as well as to conduct multi-point monitoring and replace detection equipment. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a sound detection device for transformer monitoring.

[0005] The objective of this invention can be achieved through the following technical solutions:

A rotating structure is fixed to the top of the square block. Three clamping structures are symmetrically fixed to the rotating structure. A sound monitor is mounted on each of the three clamping structures, and a microphone is fixed to one end of the outer surface of each sound monitor.

[0007] Furthermore, the rotating structure includes a middle plate, a driven rod, and a circular plate; the middle plate is fixed in the middle of the square block; one end of the driven rod is vertically fixed in the middle of the middle plate, and the other end is vertically fixed in the middle of the circular plate; three triangular rotating plates are symmetrically fixed on the top of the circular plate; a pad is fixed on one side of the outer surface of the square block; and an asynchronous motor is fixed on the upper surface of the pad.

[0008] Furthermore, the three clamping structures are respectively fixed on three triangular rotating plates; the clamping structure includes a trapezoidal frame; a push plate is fixed in the inner cavity of the trapezoidal frame; side plates are fixed on both sides of the outer surface of the push plate; clamping blocks are fixed on the outer surfaces of the two side plates.

[0009] Furthermore, two L-shaped positioning blocks are symmetrically fixed on the connecting plate; half-wheel protection frames are fixed on the top of the two L-shaped positioning blocks to fix the drive motor.

[0010] Furthermore, the output end of the drive motor is connected to a drive rod; one end of the drive rod passes through the square block and extends into it; a rotating threaded rod is fixed on the drive rod; the bottom of the rotating threaded rod is engaged with a directional threaded rod and is used to drive the moving structure to move by rotation.

[0011] Furthermore, the outer surface of the circular plate is fixed with multiple sets of gears evenly distributed; the inner cavity of the circular plate is provided with multiple positioning holes evenly distributed; the top of the driven rod is fixed with a central wheel; the outer surface of the central wheel is fixedly installed with the triangular rotating plate; and a positioning wheel is fixed at one end of the inner cavity of the triangular rotating plate.

[0012] Furthermore, a protective pad is fixed inside the asynchronous motor; a rotating rod is installed at one end of the output shaft of the protective pad; a gear is fixed on the outer surface of the rotating rod; and the outer surface of the gear meshes with a gear set.

[0013] Furthermore, grooves are provided on both sides of the outer surface of the trapezoidal frame; the side plate passes through the grooves and is connected to the push plate; a hinge plate is fixed to the end of the push plate away from the clamping block; a top plate is fixed to the bottom of the trapezoidal frame; a pneumatic cylinder is fixed to the top plate; a push rod is installed at one end of the pneumatic cylinder; the push rod passes through the top plate and the bottom of the trapezoidal frame and is hinged to the hinge plate.

[0014] Furthermore, the clamping blocks are fixed to the side plate by bolts; the two clamping blocks clamp and fix the sound monitor.

[0015] Furthermore, both ends of the push plate are provided with limiting concave plates; the inner side of the side plate is equipped with a limiting convex plate; the limiting convex plate and the limiting concave plate are the same size; the push plate and the side plate are connected by the limiting concave plate and the limiting convex plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] I. This invention designs a movable structure. By starting a drive motor, the drive rod drives a rotating threaded rod to rotate. Through the movement of the rotating threaded rod on the directional threaded rod, the movable structure moves on top of the transformer group. The sound detector installed on the movable structure also moves accordingly, thereby enabling the movement monitoring of multiple transformers and effectively changing the position of transformer groups in different locations, achieving integrated monitoring.

[0018] Second, this invention uses a rotating structure design. The start of an asynchronous motor causes the rotating rod to drive the gear to rotate, which in turn drives the gear set to drive the circular plate to rotate, thus causing the central wheel to rotate. At this time, the triangular rotating plate can also rotate. Due to the gear set, the rotation speed of the circular plate can be slowed down to once every 2.5 seconds. This allows for effective multi-point sound detection in different locations when combined with a sound monitor.

[0019] Third, through the design of the clamping structure, when it is necessary to replace the sound monitor, the push rod can be stretched by activating the pneumatic cylinder. At this time, it presses against the inside, and then the clamping blocks on both sides extend and retract to the sides, thereby releasing the clamping of the sound monitor. At this time, the sound monitor can be replaced. When clamping again, the pneumatic cylinder can be activated again, thus meeting the need for timely replacement of the sound monitor.

[0035] The working principle of the device of the present invention is as follows: First, when performing sound detection on transformer group 1, the start of the drive motor 410 causes the drive rod 411 to drive the rotating threaded rod 412 to rotate. At this time, the movement of the rotating threaded rod 412 on the directional threaded rod 44 drives the moving structure 1 to move on the top of transformer group 1, thereby monitoring the movement of multiple transformers and effectively switching the position of transformer group 1 at different locations, thus effectively maintaining the monitoring function of transformer group 1 at different locations; then, by opening the protective pad 59, the rotating rod 511 drives the gear 512 to rotate, which in turn drives the gear set 54 to rotate the circular plate 53, thereby causing the middle wheel 56 to rotate. At this time, the triangular rotating plate... 57 can rotate. Due to the gear set 54, the rotation speed of the circular plate 53 can be slowed down to once every 2.5 seconds. This allows the sound monitor 611 to perform multi-point sound detection at different positions. At this time, the driven rod 52 rotates inside the middle plate 51 to fix the rotation position. Then, the pneumatic cylinder 67 is activated to stretch the push rod 68. At this time, the limiting concave plate 614 presses against the inside of the limiting convex plate 613, and then the clamping blocks 69 on both sides extend and retract to the sides, thereby releasing the clamping of the sound monitor 611. The sound monitor 611 can be replaced at this time. When it is clamped again, the pneumatic cylinder 67 can be activated again to replace the sound monitor 611 in time, ensuring the function of detecting various transformers.
