Description

Technical Field

[0001] The invention relates to the technical field of locators, and in particular to a portable power supply fault point rapid locator and a detection process. Background Art

[0002] In the operation and maintenance of power systems, the rapid location and marking of power supply faults has always been a key issue. Traditional power supply fault detection methods often rely on manual inspections and empirical judgments. Maintenance personnel need to check step by step along the power supply lines and use various tools such as multimeters and oscilloscopes to measure electrical parameters to determine the approximate location of the fault. This method is not only time-consuming and labor-intensive, but also makes it more difficult to accurately find the fault point in a complex power grid environment.

[0003] With the development of technology, some power supply fault locators have emerged. However, the existing locators have some limitations. Although some locators can detect the fault point, they are not convenient and fast enough in marking the fault point. Some locators may require complicated operation procedures to mark, which not only increases the workload of maintenance personnel, but may also cause inaccurate or untimely marking. Moreover, many locators need to be reset or adjusted after marking a fault point before continuing to detect the next fault point, which greatly reduces the efficiency of troubleshooting and has certain shortcomings. To this end, we provide a portable power supply fault point quick locator to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to make up for the deficiencies of the prior art and provide a portable power supply fault point quick locator.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a portable power supply fault point quick locator comprises a base, a moving wheel is fixedly installed on the bottom of the base, a lifting mechanism is provided inside the base, a limiting mechanism is provided on the outside of the base, a limiting shell is fixedly connected to the top of the base, a display is fixedly installed on the front side of the limiting shell, a lifting column is slidably connected to the inner wall of the limiting shell, a carrying plate is fixedly connected to one end of the lifting column away from the limiting shell, a marking mechanism is provided above the carrying plate, an electromagnetic induction sensor is fixedly installed on the top of the carrying plate, and a limiting slide groove is provided on the top of the carrying plate.

[0006] Furthermore, the lifting mechanism includes a rotating shaft rotatably connected to the inner wall of the base, one end of the rotating shaft is fixedly connected to knob 1, and the end of the rotating shaft away from knob 1 is fixedly connected to the active bevel gear.

[0007] Furthermore, the outer surface of the active bevel gear is meshingly connected with the driven bevel gear, the inner wall of the driven bevel gear is fixedly connected with an adjusting screw, and the adjusting screw is threadedly connected to the lifting column, the outer surface of the adjusting screw is fixedly connected with two limit plates, and the outer surfaces of the two limit plates rotate with the inner wall of the base.

[0008] Furthermore, the limiting mechanism includes a fixed plate fixedly connected to the outer surface of the base, a moving rod is slidably connected to the inner wall of the fixed plate, one end of the moving rod is fixedly connected to the pull plate, and an end of the moving rod away from the pull plate is fixedly connected to a clamping block, and the clamping block is clamped with a knob.

[0009] Furthermore, the outer surface of the moving rod is slidably connected to two limit rods, one end of the limit rod is fixedly connected to the outer surface of the pull plate, and one end of the limit rod away from the pull plate is fixedly connected to the outer surface of the clamping block.

[0010] Furthermore, an elastic member is sleeved on the outer surface of the movable rod, one end of the elastic member is fixedly connected to the outer surface of the pull plate, and one end of the elastic member away from the pull plate is fixedly connected to the outer surface of the fixed plate.

[0011] Furthermore, the marking mechanism includes a bidirectional screw rod rotatably connected to the inner wall of the supporting plate, the outer surface of the bidirectional screw rod is fixedly connected to a knob 2, the outer surface of the bidirectional screw rod is threadedly connected to two movable plates, and the movable plates slide with the limiting slide groove, the inner wall of the movable plate is slidably connected to a limiting slide rod, and both ends of the limiting slide rod are fixedly connected to the inner wall of the limiting slide groove.

[0012] Furthermore, a fluorescent liquid box is fixedly connected to the outer surfaces of the two movable plates on one side close to each other, a plug is inserted into the interior of the fluorescent liquid box, a liquid-conducting cotton thread is inserted into the interior of the fluorescent liquid box and penetrates to the outer surface of the fluorescent liquid box, a sponge is fixedly connected to the outer surface of the fluorescent liquid box, and the sponge is in contact with one end of the liquid-conducting cotton thread that penetrates to the outer surface of the fluorescent liquid box.

[0013] Compared with the existing technology, this portable power supply fault point quick locator has the following beneficial effects: 1. The present invention realizes high-precision detection of power supply fault points by setting up electromagnetic induction sensors. The electromagnetic induction sensors can keenly capture changes in the electromagnetic field around the power supply line, thereby accurately judging the existence and location of the fault. By setting up a marking mechanism, the power supply fault point detected by the electromagnetic induction sensor can be quickly marked. The operation of the marking mechanism and the detection process of the electromagnetic induction sensor are independent of each other but coordinated. After marking a fault point, the electromagnetic induction sensor can still work normally and continue to detect the next fault point, which greatly improves the overall efficiency of troubleshooting.

[0014] 2. The present invention can drive the rotating shaft and the active bevel gear to rotate by rotating knob 1. Since the active bevel gear is meshed with the driven bevel gear, the active bevel gear will drive the driven bevel gear, the adjusting screw and the limit plate to rotate. The rotation of the adjusting screw can drive the lifting column to rise and fall smoothly. This design enables the positioner to adapt to the detection needs of power supply facilities at different heights without the need for external tools or complicated operations, thereby improving the convenience and efficiency of detection.

[0015] 3. The present invention can drive the moving rod, the limiting rod and the blocking block to move with them by pulling the pulling plate. At the same time, the pulling plate can stretch the elastic part to deform it and store a certain amount of elastic potential energy. When the lifting mechanism is adjusted to a suitable position, the pulling plate is released. At this time, the compressed elastic part releases the elastic potential energy, which in turn drives the blocking block to move in the opposite direction so that the end teeth are inserted into the tooth gap of the knob, thereby avoiding the self-rotation of the adjusting screw, thereby preventing the lifting column from being displaced due to accidental shaking or external force, thereby ensuring the stability of the equipment during the detection process and improving the accuracy of the detection results.
