Description

Technical Field

[0001] The utility model relates to the technical field of leakage detection, in particular to a leakage detection device for electric wires of power equipment. Background Art

[0002] Wires will gradually age as they are used. In addition, a humid working environment will accelerate the aging process, causing the insulation performance of the wire surface to deteriorate. When the insulation resistance is too low, the wire will leak electricity.

[0003] The utility model patent with patent application publication number CN 218938469 U discloses a device for detecting leakage of electric wires in electric power equipment, comprising a transparent insulating shell, a metal end cap being threadedly connected to the right end of the transparent insulating shell, a fixing block being installed at the left end of the transparent insulating shell, a second mounting seat being installed at the upper and lower ends of the fixing block, two probes being rotatably connected at the front and rear ends of the fixing block, the two probes being symmetrically distributed up and down, the probes being in a semicircular ring structure, a circular cavity being formed between the two probes, and a first mounting seat being installed on the outer surfaces of the two probes.

[0004] The utility model increases the contact area between the probe and the outer skin of the wire by arranging two semicircular probes to contact the outer skin of the wire, thereby improving the efficiency of wire leakage detection. By arranging magnets to strengthen the connection between the two probes, the probability of the probe detaching from the wire when moving along the wire is reduced.

[0005] However, the above device still has some shortcomings in actual use. The most obvious one is that when the probe moves on the surface of the outer skin, it will rub against the outer skin. This friction will not only cause movement jams and increase the difficulty of operation for operators, but also easily cause scratches to the outer skin, thereby causing damage to the outer skin, further shortening the service life of the outer skin, which is inconvenient in actual use.

[0006] Therefore, it is necessary to invent a device for checking leakage of electric wires of electric equipment to solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to provide a device for checking electric wire leakage of electric power equipment to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for checking leakage of electric wires of electric power equipment, comprising a holding mechanism, wherein a rolling clamping mechanism is provided at the left end of the holding mechanism;

[0009] The rolling clamping mechanism comprises a conductive bracket, a conductive shaft, a conductive concave wheel, an insulating plate and a mounting side plate;

[0010] The conductive bracket, the conductive shaft, the conductive cam, the insulating plate and the mounting side plate are each provided with two, the two conductive brackets are arranged opposite to each other, the two conductive shafts are respectively rotatably arranged on the inner sides of the two conductive brackets through bearings, the two conductive cams are respectively fixedly sleeved and arranged on the outer sides of the two conductive shafts, the two insulating plates are respectively fixedly arranged on the right sides of the two conductive brackets, the two mounting side plates are both fixedly connected to the transparent insulating shell, and the two conductive brackets are rotatably arranged between the two mounting side plates through pins.

[0011] Preferably, the holding mechanism includes a transparent insulating shell, a resistor, a neon tube, a spring and a metal end cap.

[0012] Preferably, the conductive bracket is electrically connected to the resistor, the resistor, neon tube and spring are slidably arranged in sequence from left to right inside the transparent insulating shell, the metal end cover is detachably arranged at the right end of the transparent insulating shell, and the metal end cover is threadedly connected to the transparent insulating shell.

[0013] Preferably, a torsion spring is fixedly connected between the conductive bracket and the mounting side plate.

[0014] Technical effects and advantages of the utility model:

[0015] The utility model is provided with a rolling clamping mechanism to facilitate holding the transparent insulating shell, and then the thumb and index finger are used to press the two insulating plates respectively, so that the two insulating plates are moved closer to the transparent insulating shell. At this time, the insulating plates drive the conductive bracket to rotate with the pin shaft as the center. As the conductive bracket continues to rotate, the two conductive brackets drive the two conductive concave wheels to separate to both sides, and then the device is moved so that the wire is located between the two conductive concave wheels, and then the insulating plates are released. Driven by the torsion spring, the two conductive concave wheels are clamped on the outside of the wire and contact the outer skin of the wire. Then, the transparent insulating shell is moved to make the conductive concave wheels roll on the outside of the outer skin, and then the continuous detection operation is started. If the wire leaks due to aging or broken outer skin, the current passes through the resistor and the neon tube. The neon tube is energized and emits light, thereby warning the detection personnel. Compared with the same type of device in the prior art, the utility model uses the continuously rolling conductive concave wheels to complete the detection operation, which can avoid the situation of movement jamming, and the operation is more convenient. In addition, the situation of scratching the outer skin can be avoided, and the actual use effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides Figure 1-2 The device shown is a leakage detection device for electric wires of electric power equipment, comprising a holding mechanism 1, wherein a rolling clamping mechanism 2 is arranged at the left end of the holding mechanism 1.

[0023] like Figure 2 As shown, the rolling clamping mechanism 2 includes a conductive bracket 21, a conductive shaft 22, a conductive concave wheel 23, an insulating plate 24 and a mounting side plate 25, wherein the conductive bracket 21, the conductive shaft 22, the conductive concave wheel 23, the insulating plate 24 and the mounting side plate 25 are each provided with two, the two conductive brackets 21 are arranged opposite to each other, the two conductive shafts 22 are respectively rotatably arranged on the inner sides of the two conductive brackets 21 through bearings, the two conductive concave wheels 23 are respectively fixedly sleeved and arranged on the outer sides of the two conductive shafts 22, the two insulating plates 24 are respectively fixedly arranged on the right sides of the two conductive brackets 21, the two mounting side plates 25 are both fixedly connected to the transparent insulating shell 11, a torsion spring is fixedly connected between the conductive bracket 21 and the mounting side plate 25, and the two conductive brackets 21 are rotatably arranged between the two mounting side plates 25 through a pin shaft.

[0024] By setting the above structure, it is convenient to hold the transparent insulating shell 11, and then use the thumb and index finger to press the two insulating plates 24 respectively, so that the two insulating plates 24 are moved closer to the transparent insulating shell 11. At this time, the insulating plates 24 drive the conductive bracket 21 to rotate around the pin shaft.

At this time, the insulating plates 24 drive the conductive bracket 21 to rotate around the pin shaft. As the conductive bracket 21 continues to rotate, the two conductive brackets 21 drive the two conductive concave wheels 23 to separate to both sides, and then the device is moved so that the wire is located between the two conductive concave wheels 23. Then the insulating plates 24 are released. Driven by the torsion spring, the two conductive concave wheels 23 are clamped on the outside of the wire and contact with the outer skin of the wire. Then, the transparent insulating shell 11 is moved to make the conductive concave wheels 23 roll on the outside of the outer skin, and then the continuous detection operation is started.
