Description

Technical Field

[0001] This invention relates to the field of line loss detection technology, and more specifically to a line loss detection device. Background Technology

[0002] The energy loss that occurs when electrical energy is transmitted through transmission lines is called line loss. In addition to the transmission lines, other transmission and transformation equipment such as transformers in the power network also cause energy losses. The sum of these energy losses (including line losses) is called network loss.

[0003] Currently, line loss detection devices typically involve running cables through current transformers and moving them to detect current, along with using cameras to photograph the cables and detect any damage. However, in actual testing, pulling and moving the cables inevitably causes them to shift and sway, resulting in poor stability. Furthermore, even with multiple cameras, it is difficult to capture a comprehensive, blind-spot-free view of the entire line, significantly impacting the effectiveness of line loss detection. Summary of the Invention

[0004] The purpose of this invention is to provide a line loss detection device. By setting a conductor mechanism, the conductor mechanism can drive the cable to move intermittently, thereby enabling the current transformer to detect the line in segments. Furthermore, by setting a support plate and a moving component, when detecting each segment of the line, the support plate can drive the current transformer to move linearly along the line, thus achieving relative motion. This allows for efficient and stable detection of the line, avoiding line deviation and shaking, and solving the aforementioned shortcomings in the technology.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] This invention provides, for example Figures 1-8 The line loss detection device shown includes: The base 1 has a fixing frame 3 symmetrically arranged at both ends of the top of the base 1. The top of the fixing frame 3 is connected to the fixing plate 4, and the top of the fixing plate 4 is provided with a wire mechanism. The wire guide mechanism is symmetrically arranged on the fixed covers 5 at both ends of the top of the fixed plate 4. The inner sides of the two fixed covers 5 are rotatably connected to guide wheels 6 through rotating shafts. The top of the fixed cover 5 is fixed with a first motor 7. The output end of the first motor 7 is connected to the output shaft of the guide wheel 6. The fixed plate 4 is provided with a distance adjustment component, which is used to adjust the distance between the two guide wheels 6.

[0020] The adjustable distance assembly includes a first sliding cavity 8 opened on the top of the fixed plate 4. A bidirectional lead screw 9 is rotatably connected inside the first sliding cavity 8 via a bearing. Movable blocks 10 are symmetrically connected to both ends of the bidirectional lead screw 9 via threads. The top ends of the two movable blocks 10 are respectively fixedly connected to two fixed covers 5. One end of the bidirectional lead screw 9 extends outside the fixed plate 4 and is connected to a fixed handle 11.

[0021] In use, the cable to be tested can be threaded between the two sets of guide wheels 6 and the current transformer 13. The first motor 7 drives the guide wheels 6 to rotate inside the fixed cover 5, so that the two adjacent guide wheels 6 can rotate at the same time and drive the cable forward. Since the cable passes through the detection hole of the current transformer 13, the current transformer 13 can be the current transformer disclosed in the patent document with patent number CN115236443A and patent name "A Line Loss Detection Device". The current transformer can be connected to the power meter through the wire, so that the current of the line passing through it can be detected. Furthermore, by turning the fixed handle 11, the fixed handle 11 drives the bidirectional lead screw 9 to rotate. Then, the bidirectional lead screw 9 can drive two movable blocks 10 to move towards or away from each other in the first sliding cavity 8. After that, the movable blocks 10 drive the fixed cover 5 to move, thereby allowing two adjacent guide wheels 6 to move towards or away from each other. This allows the distance between the two guide wheels 6 to be adjusted to accommodate cables of different diameters, greatly improving the applicability of the device.

[0022] Support plate 12 is movably disposed on the top of base 1 and is located between two fixed frames 3. Current transformer 13 is fixed on the top of support plate 12. A moving component is provided on base 1 and the moving component is used to drive support plate 12 to move. The moving component includes a second sliding cavity 21 opened on the top of the base 1. A threaded rod 22 is rotatably connected inside the second sliding cavity 21 via a bearing. A slider 23 is threadedly connected to the outer wall of the threaded rod 22. The top end of the slider 23 is fixedly connected to the support plate 12. A second motor 24 is fixed to one end of the base 1. The output end of the second motor 24 extends into the second sliding cavity 21 and is connected to the threaded rod 22.

[0023] Guide blocks 26 are symmetrically fixed on both sides of the bottom of the support plate 12, and guide grooves 25 matching the guide blocks 26 are opened on the top of the base 1.

[0024] A positioning ring 14 is connected to one side of the current transformer 13. A rotating ring 15 is rotatably mounted on one side of the positioning ring 14. Three cameras 17 are arranged in a ring array on the inner side of the rotating ring 15. A limiting component is provided between the rotating ring 15 and the positioning ring 14. A driving component is provided on the support plate 12, and the driving component is used to drive the rotating ring 15 to rotate.

[0025] The limiting assembly includes multiple limiting blocks 18 fixed to the side wall of the rotating ring 15 facing the positioning ring 14, and the side wall of the positioning ring 14 is provided with limiting grooves 19 that match the limiting blocks 18.

[0026] The drive assembly includes a gear ring 16 fixed to the outside of the rotating ring 15, a third motor 27 fixed to one end of the top of the support plate 12, and a gear 28 connected to the output end of the third motor 27, and the gear 28 meshing with the gear ring 16.

[0027] During testing, the cable can be moved intermittently by the conductor mechanism, so that the current transformer 13 can test the line in segments. When testing each segment of the line, the conductor mechanism stops working and the cable is stationary. At this time, the moving component can be activated, so that the second motor 24 drives the threaded rod 22 to rotate forward and backward. Then the threaded rod 22 drives the slider 23 to move back and forth in the second sliding cavity 21. After that, the slider 23 drives the support plate 12 to move, so that the support plate 12 can drive the current transformer 13 to move linearly along the line, thus realizing its relative movement. In this way, the line can be tested efficiently and stably, avoiding line deviation and shaking. Meanwhile, during the movement of the current transformer 13, the camera 17 inside the rotating ring 15 on one side can take pictures of the line section. The captured data can be transmitted to the controller to further monitor whether the line is damaged. During the movement and shooting, the gear 28 can be driven by the third motor 27 to rotate, which in turn drives the gear ring 16 to rotate. Then, the gear ring 16 drives the limit block 18 to slide in the limit groove 19 through the rotating ring 15, so that the rotating ring 15 drives the multiple cameras 17 inside to rotate at a uniform speed. This allows the camera 17 to shoot the line in a straight line while also making circular motion to shoot the line in 360 degrees, thereby achieving all-round detection without blind spots, greatly improving detection efficiency and ensuring detection effect.

[0028] L-shaped plates 2 are fixed on both sides of the bottom of the base 1.

[0029] A handle 20 is fixed to one end of the base 1 relative to the second motor 24, and the handle 20 is U-shaped.

[0030] The base 1 can be supported by the L-shaped plate 2, and the handle 20 makes it easy to pick up the moving device.
