Description

Technical Field

[0001] This utility model relates to the field of fault detection technology, specifically a substation fault detection device. Background Technology

[0002] In power systems, the stable operation of substations is crucial. To promptly detect potential faults and ensure the safety of power supply, fault detection devices are widely used. Currently, many substation fault detection devices use cameras to acquire images. By analyzing the acquired images, they determine whether there are faults in the equipment within the substation, such as damage to the equipment's appearance, loose components, abnormal overheating of lines, or breakage.

[0003] Currently, many substations rely on cameras to capture images and detect equipment faults. However, in practical applications, factors such as installation environment and equipment layout often necessitate fine-tuning of the camera position to obtain high-quality images. Existing fault detection devices struggle to flexibly adjust camera positions; once fixed in place, their viewing angle and shooting range are difficult to change. If the initial installation position is not ideal, problems such as blind spots in critical equipment, image angle deviations, or poor clarity can easily arise, leading to inaccurate and delayed fault diagnosis. This increases the burden of manual inspections and may result in missed faults causing power accidents, resulting in economic losses and safety risks. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a substation fault detection device.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A substation fault detection device includes a housing;

[0007] Adjustment components, including:

[0008] The rotating plate is hinged to the top of the housing via the base;

[0009] A tie rod is inserted through the rotating plate and can slide along the axial direction of the rotating plate;

[0010] The turntable is spherically hinged to the top of the pull rod;

[0011] The camera is fixed on the turntable, and the lens axis is kept perpendicular to the detection part of the device by the adjustment component.

[0012] Preferably, the base is provided with a first locking knob, the screw end of the first locking knob abuts against the rotating plate, and when tightened, it restricts the rotation of the rotating plate around the hinge axis.

[0013] Preferably, the rotating plate is provided with a second locking knob, the screw end of the second locking knob abuts against the pull rod, and when tightened, it restricts the sliding of the pull rod along the axial direction.

[0014] Preferably, a display screen is provided on one side of the housing, and the display screen is electrically connected to the camera.

[0015] Preferably, the housing has heat dissipation holes.

[0016] Preferably, the housing has a groove, and the groove contains an expansion interface.

[0017] Compared with existing technologies, the beneficial effects of this utility model are as follows: The camera mounted on the adjustment assembly can adjust its angle according to the position of the equipment under test, enabling flexible rotation and position adjustment in both horizontal and vertical directions. Operators can precisely adjust the camera's shooting angle and distance based on the spatial layout of transformers, circuit breakers, and other equipment under test within the substation, ensuring that critical parts of the equipment are fully captured in the center of the image. This reduces blind spots in equipment detection, improves fault identification accuracy, enhances the intelligent operation and maintenance level of the substation, and effectively avoids potential power safety hazards caused by oversights in detection.

[0026] Example

[0027] like Figures 1-4 As shown, a substation fault detection device includes a housing 1, in which a main control chip (not shown in the text) is installed. The chip is an Ascend310B4 processor with a Da Vinci architecture and a CANN heterogeneous computing architecture. It enables the deployment of model training to the edge side and is equipped with a 4-core 64-bit processor + AI processor, supporting a maximum computing power of 20 TOPS. It is widely used in AI edge computing, deep vision learning, video image analysis and other fields.

[0028] A display screen 11 is provided on one side of the housing 1. The display screen 11 is electrically connected to the camera 3 and adopts a 7-inch IPS touch screen as a human-machine interface. It is used to display the images or detection data collected by the camera 3 in real time and can receive and process the signals transmitted by the camera 3. The housing 1 has heat dissipation holes 12 and a groove 13. The groove 13 has an expansion interface 14 (supporting GPIO, UART, I2C, SPI, PWM, etc.) to enhance the expandability of the device and can flexibly connect various peripherals according to different detection needs.

[0029] Adjustment component 2, which includes:

[0030] The rotating plate 22 is hinged to the top of the housing 1 via the base 21; the base 21 is provided with a first locking knob 25, the screw end of the first locking knob 25 abuts against the rotating plate 22, and when tightened, it restricts the rotation of the rotating plate 22 around the hinge axis; by rotating the rotating plate 22, the angle and height of the camera 3 can be adjusted to cover a wider detection area.

[0031] A pull rod 23 is mounted on a rotating plate 22 and can slide along the axial direction of the rotating plate 22. A second locking knob 26 is provided on the rotating plate 22. The screw end of the second locking knob 26 abuts against the pull rod 23. When tightened, it restricts the sliding of the pull rod 23 along the axial direction. The height of the camera 3 can be adjusted by extending and retracting the pull rod 23. Combined with the spherical hinge structure of the turntable 24, the elevation angle of the camera 3 lens can be adjusted so that the lens axis can be aligned with the parts to be tested at different heights.

[0032] The turntable 24 is spherically hinged to the top of the pull rod 23; it provides multi-dimensional adjustment capabilities, and in conjunction with the rotation of the rotating plate 22 and the extension and retraction of the pull rod 23, it can precisely adjust the posture of the camera 3 to ensure that the lens axis is perpendicular to the surface of the part to be inspected.

[0033] like Figure 5 As shown, camera 3 is fixed on turntable 24 and is used to collect image or video data of the detection area. It is electrically connected to the main control chip and transmits the image data to the AI ​​processor for analysis.

[0034] Camera 3 is vertically aligned with the part to be inspected, which can avoid image distortion caused by the tilt of the shooting angle and ensure that the geometry and size ratio of the inspected part are accurately reproduced in the image. For example, when measuring the size of a workpiece or identifying minor defects, vertical shooting can reduce visual errors. When a fault point appears on the photographed part, the fault point can be marked and identified to achieve the effect of fault detection.

[0035] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
