Description

Technical Field

[0001] This utility model relates to the technical field of ultrasonic testing, specifically to a real-time ultrasonic testing device for substations. Background Technology

[0002] In the operation and maintenance of substation power equipment, ultrasonic testing is a key method for detecting partial discharge defects. Its core relies on ultrasonic line inspection instruments to monitor the condition of equipment such as transformers, switchgear, and reactors. With the increasingly complex layout of substation equipment (including equipment in confined spaces and high-voltage equipment at high altitudes) and the ever-increasing demands of operation and maintenance, it is necessary to balance rapid inspection with long-term monitoring. Existing ultrasonic testing devices are mostly handheld. When conducting long-term monitoring of specific inspection points in a substation, maintenance personnel holding the equipment for extended periods can easily experience fatigue symptoms such as hand muscle tension and soreness. With accumulated fatigue, operators may develop uncontrollable physiological tremors, causing the probe to deviate from the test point, increasing the risk of missed defects and affecting the accurate judgment of the equipment's operating status. Utility Model Content

[0003] This utility model proposes a real-time ultrasonic detection device for substations, which enables rapid switching between handheld and supported modes through the coordinated action of the support mechanism and the connecting mechanism, adapting to multiple detection scenarios.

[0004] Therefore, the technical solution adopted is as follows:

[0005] A real-time ultrasonic testing device for substations includes a testing body connected to a support mechanism via a connecting mechanism. The connecting mechanism includes a U-shaped frame and a fixing block. The U-shaped frame is rotatably connected to the bottom of the testing body. The fixing block is fixed to the top of the support mechanism. A rotating block is rotatably connected to the top of the fixing block. A splined shaft is fixed to the top of the rotating block. A connecting block is fixed on the U-shaped frame. The connecting block has a spline groove adapted to the splined shaft. A screw passing through the splined shaft and the connecting block is fixed on the rotating block. A nut with matching threads is fitted on the screw at the end where the connecting block is located.

[0006] A further technical solution is that the detection body also includes a handle fixed at the bottom, a frustum receiver fixed vertically to the handle, an aiming device fixed on the frustum receiver, a signal converter fixed on one side of the frustum receiver, a touch screen fixed at the observation end of the frustum receiver, and a U-shaped frame located at the bottom of the frustum receiver and rotatably connected to it.

[0007] A further technical solution is that a cover plate is rotatably connected to the touch screen.

[0008] A further technical solution is that the support mechanism includes a telescopic rod, the fixing block is fixed to the top of the telescopic rod, the telescopic rod is configured in multiple sections, and each section of the single rod has a second locking bolt threaded onto its side wall.

[0009] A further technical solution is that the side wall of the telescopic rod is fitted with a slider that is slidably connected to it, and multiple support frames are rotatably connected to the outer edge of the slider. A connecting rod is rotatably connected to the support frame, and the other end of the connecting rod is rotatably connected to the bottom of the telescopic rod. A screw hole is opened on the slider, and a first locking bolt matching its thread passes through the screw hole.

[0010] The working principle and beneficial effects of this application are as follows:

[0011] Through the coordinated action of the support and connection mechanisms, the system enables rapid switching between handheld and support modes, adapting to various detection scenarios. The handheld mode is suitable for rapid inspection of confined spaces and dispersed equipment, while the support mode is suitable for long-term detection scenarios. On the one hand, it frees up the hands and avoids fatigue caused by prolonged holding. On the other hand, through stable support and precise angle locking, it ensures the continuity and accuracy of long-term monitoring data, improving operational flexibility.

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0020] like Figures 1-5 As shown, a real-time ultrasonic detection device for a substation includes a detection body 1. The detection body 1 is connected to a support mechanism 7 via a connecting mechanism 6. The connecting mechanism 6 includes a U-shaped frame 61 and a fixing block 63. The U-shaped frame 61 is rotatably connected to the bottom of the detection body 1. The fixing block 63 is fixed to the top of the support mechanism 7. A rotating block 64 is rotatably connected to the top of the fixing block 63. A spline shaft 65 is fixed to the top of the rotating block 64. A connecting block 62 is fixed on the U-shaped frame 61. The connecting block 62 has a spline groove 68 that matches the spline shaft 65. A screw 66 that passes through the spline shaft 65 and the connecting block 62 is fixed on the rotating block 64. A nut 67 with matching threads is fitted on the end of the screw 66 where the connecting block 62 is located.

[0021] In this embodiment, the detection body 1 also includes a handle 2 fixed to the bottom, a frustum receiver 3 fixed perpendicularly to the handle 2, a sight 4 fixed on the frustum receiver 3, a signal converter 5 fixed on one side of the frustum receiver 3, a touch screen 8 fixed to the observation end of the frustum receiver 3, and a U-shaped frame 61 located at the bottom of the frustum receiver 3 and rotatably connected to it. A cover plate 9 is rotatably connected to one side of the touch screen 8. The cover plate 9 adopts a hinged structure, which protects the touch screen 8. It can be opened during detection to avoid obstructing the view, and closed when idle or during transportation to prevent the screen from being scratched.

[0022] The ultrasonic circuit inspection instrument consists of a handle 2, a frustum receiver 3, a sight 4, a signal converter 5, and a touch screen 8. The handle 2 contains a rechargeable lithium battery and a charging port on its surface. The rechargeable lithium battery provides power to the inspection device. The frustum receiver 3 is used to acquire ultrasonic signals emitted by the power line when it is energized. These signals are then converted into electrical signals by the signal converter 5 and analyzed. The sight 4 allows the user to aim the instrument at the inspection location. The main body 1 is also equipped with a GPS module to obtain the current geographical coordinates of the instrument and mark the location of potential circuit faults, so that maintenance personnel can inspect the circuit. The touch screen provides human-computer interaction, receives the user's touch operations, displays the inspection and analysis results of the equipment, displays the ultrasonic waveform results, and various indicators of the equipment.

[0023] Specifically, the maintenance personnel hold handle 2 and lift the device, using aiming device 4 for initial calibration to ensure normal laser beam emission. The truncated cone receiver 3 enters the detection state and begins receiving ultrasonic signals. The maintenance personnel move the device to the target equipment, aiming the laser beam at the suspected discharge area through aiming device 4, adjusting the hand angle so that the truncated cone receiver 3 is directly facing the detection point. The truncated cone receiver 3 transmits the received ultrasonic signal to signal converter 5. Signal converter 5 converts the mechanical signal into an electrical signal and filters out noise, then transmits it to the main control chip inside the detection body 1. After processing, the chip displays the data in real time on display screen 8. The maintenance personnel determine whether the equipment has partial discharge defects based on the data.

[0024] The support mechanism 7 provides stable support for the ultrasonic line inspection instrument above, suitable for long-term testing at fixed points. The ultrasonic line inspection instrument is connected to the support mechanism 7 via the connecting mechanism 6, which controls the ultrasonic line inspection instrument to rotate with the rotating block 64, so that the ultrasonic line inspection instrument is aligned with the detection in the horizontal direction. The ultrasonic line inspection instrument also rotates around the rotation point of the U-shaped frame 61 to adjust the pitch angle of the ultrasonic line inspection instrument, so that the laser beam is aligned with the detection point. In addition, the detachable design of the connecting mechanism 6 allows for quick switching between handheld and support modes, adapting to multiple detection scenarios. The handheld mode is suitable for rapid inspection of confined spaces and scattered equipment, while the support mode is suitable for long-term testing scenarios. On the one hand, it frees up the hands and avoids fatigue caused by prolonged holding. On the other hand, through stable support and precise angle locking, it ensures the continuity and accuracy of long-term monitoring data, improving the flexibility of operation and maintenance.

[0025] It should be noted that the U-shaped frame 61 and the frustum receiver 3 are connected by bolts and nuts to form a damped rotation structure. The damping structure allows the ultrasonic line inspection instrument to be adjusted around the U-shaped frame 61 at multiple angles, and can be stably locked at any angle after adjustment. The rotating block 64 and the fixed block 63 form a damped rotation connection, providing a horizontal damped rotation reference for the rotating block 64, ensuring that the rotating block can be stably locked after adjustment.

[0026] Specifically, the splined shaft 65 is fixed to the top of the rotating block 64 and precisely matches the spline groove 68 of the connecting block 62, so that the connecting block 62 and the rotating block 64 rotate synchronously. When the nut 67 is tightened, the connecting block 62 can be tightly pressed onto the rotating block 64, thereby establishing a connection between the ultrasonic circuit inspector and the support mechanism 7.

[0027] like Figure 5As shown, the support mechanism 7 includes a telescopic rod 71, and the fixing block 63 is fixed to the top of the telescopic rod 71. The telescopic rod 71 is multi-sectioned, and each section has a second locking bolt 76 threaded onto its side wall. The telescopic rod 71 is a multi-segment telescopic metal rod. By stretching or retracting the telescopic rod, it can adapt to detection targets of different heights. When the telescopic rod 71 is stretched to the target height, the second locking bolt 76 is tightened, and its end presses against the inner rod of the telescopic rod to prevent the inner rod from sliding down and ensure stable support height.

[0028] In addition, the side wall of the telescopic rod 71 is fitted with a slider 72 that is slidably connected to it. Multiple support frames 74 are rotatably connected to the outer edge of the slider 72. A connecting rod 75 is rotatably connected to the support frame 74. The other end of the connecting rod 75 is rotatably connected to the bottom of the telescopic rod 71. A screw hole is opened on the slider 72, and a first locking bolt 73 matching its thread is inserted in the screw hole.

[0029] The number of support frames 74 can be set to 3, and the 3 support frames 74 are distributed in a triangle. When unfolded, slide the slider 72 downward. The slider 72 drives the 3 support frames 74 to open outward through the connecting rod 75. Tighten the first locking bolt 73 to fix the position of the slider 72 and ensure that the support frames 74 do not retract, thereby providing stable support for the ultrasonic line inspection instrument above. When retracted, loosen the first locking bolt 73 and slide the slider 72 upward. The slider 72 drives the support frames 74 to close together through the connecting rod 75 and fit tightly against the telescopic rod 71 without occupying extra space.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
