Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a power supply and distribution wiring testing device. Background Technology

[0002] The power supply and distribution system is the electricity user of the power system and an important component of the power system. The wiring points are the path of current. If there are faults such as poor contact, insulation damage, or short circuit, it may lead to electric shock, arc flashover, or even electric shock accidents, endangering the safety of maintenance personnel and nearby people. Therefore, it is necessary to inspect the wiring points.

[0003] A power supply and distribution wiring testing device with announcement number CN219715713U uses two movable rods to clamp the wires together, so that the wire joints are held by two conductive plates, making it easy to contact the wires with the conductive plates. If there are defects in the wire wiring and the wires are exposed, the conductive plates will transmit current to the LED beads, causing the LED beads to light up, thus facilitating the testing of the wire wiring.

[0004] However, if the conductive sheet is fixed only by the arc-shaped groove, the contact pressure between the conductive sheet and the terminal being tested may be insufficient on terminals of different sizes, shapes or surface conditions, which may easily lead to poor contact between the conductive sheet and the terminal surface, resulting in inaccurate test results. Utility Model Content

[0005] (I) Technical problems to be solved

[0006] The technical problem to be solved by this utility model is to overcome the defect that the above-mentioned arc-shaped conductive sheet is prone to poor contact with the wiring surface, and to provide a power supply and distribution wiring testing device.

[0007] (II) Technical Solution

[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a power supply and distribution wiring detection device, including a fixed base, a mounting base connected to the fixed base via a support rod, a support plate rotatably connected to the mounting base, a fixed ring provided on the support plate, multiple sets of detection components provided inside the fixed ring, an equipment box provided on one side of the support plate near the detection components, multiple LED beads electrically connected to the equipment box, the detection components including several rotatably arranged conductive plates, an annular groove provided inside the fixed ring, a fixed groove communicating with the annular groove on one side of the annular groove, a fixed plate fixedly connected inside the fixed groove, a rotating ring rotatably provided on the fixed plate, several toothed blocks arranged in a circular array on the inner wall of the rotating ring, a rotating shaft fixedly connected to the conductive plates, one end of the rotating shaft rotatably connected to the fixed plate, and a gear meshing with the toothed blocks fixedly connected to the rotating shaft.

[0009] As an improvement: the number of detection components and lamp beads is three, and a group of detection components is electrically connected to a lamp bead through a wire. The fixing plate and the rotating shaft are made of conductive material, while the gears, gear blocks and rotating rings are made of insulating material.

[0010] As an improvement: the fixed ring is provided with a sliding hole communicating with the ring groove, the rotating ring is connected with a fixed block, and the fixed block is symmetrically connected with positioning rods in the front and back. Multiple positioning grooves matching the positioning rods are arrayed on both sides of the sliding hole.

[0011] As an improvement: the two positioning rods are connected by a spring, the fixing block has symmetrically arranged through holes, the positioning rods are connected to a control plate, the control plate is slidably disposed in the through hole and one end extends to the outside of the through hole.

[0012] As an improvement, the support plate is rotatably connected to the mounting base by bolts and fastening nuts.

[0013] As an improvement: a suction cup is connected inside the fixed base via a connecting rod, one end of which extends above the fixed base and is rotatably connected to a pressing handle.

[0014] (III) Beneficial Effects

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] 1. The setting of several conductive plates on the detection component not only provides stable support for wiring of different sizes and ensures stability during the detection process, but also the setting of multiple contact points makes the conductive plates and wiring more fully contacted, ensuring the accuracy of the detection. At the same time, the positioning rod inserted into the positioning groove can fix the position of the conductive plates to ensure good and stable contact pressure between the conductive plates and wiring.

[0017] 2. The detection components are set in three groups, located on the two wire surfaces and at the connection point of the two wires, which can detect multiple locations at the same time, thus improving the detection efficiency. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0027] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0028] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0029] Combined with appendix Figures 1 to 3 As shown, a power supply and distribution wiring testing device includes a fixed base 1, a mounting base 3 connected to the fixed base 1 via a support rod 2, a support plate 4 rotatably connected to the mounting base 3, a fixing ring 5 on the support plate 4, and multiple sets of testing components inside the fixing ring 5. An equipment box 6 is located on one side of the testing components on the support plate 4, and three LED beads 7 are electrically connected to the equipment box 6. The number of testing components is the same as the number of LED beads 7, also three sets. Each set of testing components is electrically connected to one LED bead 7 via a wire. The fixed plate 11 and rotating shaft 14 are made of conductive material, while the gear 15, gear block 13, and rotating ring 12 are made of insulating material. The fixed base 1 and fixing ring 5 are also made of insulating material to ensure safety during the testing process.

[0030] Among them, the combination of appendix Figures 1 to 3As shown, the support plate 4 is rotatably connected to the mounting base 3 by bolts 23 and fastening nuts 24. This design allows adjustment of the angle between the support plate 4 and the fixed base 1 so that the fixed base 1 can be installed on a certain plane. The fixed base 1 is connected to a suction cup 25 by a connecting rod 26. One end of the connecting rod 26 extends above the fixed base 1 and is rotatably connected to a pressing handle 27. After placing the wiring in the fixing ring 5, the fixed base 1 is kept horizontal with the placement surface, and the suction cup 25 is attached to the surface of the placement surface. Rotating the pressing handle 27 causes the suction cup 25 to expel air and firmly adhere to the placement surface, ensuring the stability of the device during the testing process.

[0031] To improve detection accuracy, combined with the attached Figure 4 and Figure 5 As shown, the detection component includes several rotatably arranged conductive sheets 8. The fixed ring 5 has an annular groove 9, and a fixed groove 10 communicating with the annular groove 9 is provided on one side. A fixed plate 11 is fixedly connected in the fixed groove 10. A rotating ring 12 is rotatably arranged on the fixed plate 11. Several toothed blocks 13 are arranged in a circular array on the inner wall of the rotating ring 12. A rotating shaft 14 is fixedly connected to the conductive sheets 8. One end of the rotating shaft 14 is rotatably connected to the fixed plate 11. A gear 15 that meshes with the toothed blocks 13 is fixedly connected to the rotating shaft 14.

[0032] At the same time, to ensure good and stable contact pressure between the conductive sheet 8 and the wiring, combined with the attached... Figure 4 and Figure 6 As shown, the fixed ring 5 is provided with a sliding hole 16 communicating with the ring groove 9, and a fixed block 17 is connected to the rotating ring 12. The fixed block 17 is slidably located in the sliding hole 16. Positioning rods 18 are symmetrically connected in the fixed block 17. Multiple positioning grooves 19 matching the positioning rods 18 are arrayed on both sides of the sliding hole 16. Two positioning rods 18 are connected by a spring 20. The fixed block 17 is provided with symmetrically arranged through holes 21. A control plate 22 is connected to the positioning rods 18. The control plate 22 is slidably located in the through hole 21 and one end extends to the outside of the through hole 21.

[0033] Pass the wiring through the retaining ring 5, positioning the connection point of the two wirings at the detection component in the middle. Push the control plates 22 on both sides towards the center, causing the positioning rod 18 to retract into the retaining block 17. Simultaneously, the retaining block 17 rotates along the sliding hole 16, and the rotating ring 12 rotates to drive the gear 15, thereby moving the conductive sheet 8 and adjusting its position relative to the wiring surface until the conductive sheet 8 is in close contact with the wiring surface. At this point, the positioning rod 18 is reinserted into the corresponding positioning slot 19 to ensure the stability of the conductive sheet 8 during detection. When there is a leakage, current will be transmitted to the equipment box 6 through the conductive sheet 8, causing the LED 7 to flash. The flashing pattern of the LED 7 indicates the leakage condition of the wiring.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
