Technical Field

[0001] The invention relates to the technical field of wire outer insulation layer detection, in particular to a measuring device. Background Art

[0002] Insulated wires are made of one or more conductors in contact with each other and covered with an insulating layer. They are used to transmit electricity or information from one place to another. Cable detection is often required during production maintenance. The insulating layer on the outside of the conductor may be rubbed and corroded due to swaying and special environments during use. In the above cases, small holes are likely to appear on the insulating layer of the wire, which directly affects the insulation of the wire.

[0003] Therefore, the insulation of the wire needs to be replaced and tested after a period of use. The existing detection method through naked eye observation cannot effectively detect the above-mentioned tiny holes and gaps, and there are problems such as incomplete detection and easy leakage. At the same time, the humidity of the insulation layer has a great influence on its insulation performance. During the detection process, the insulation performance of the insulation layer also needs to be tested under extreme humidity.

[0004] Therefore, a measuring device is proposed to address the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a measuring device to solve the problem raised in the above background technology that "the insulation of the wire needs to be replaced and tested after being used for a period of time, and the existing detection method through naked eye observation cannot effectively detect the above-mentioned tiny holes and gaps, and there are problems such as incomplete detection and easy leakage. At the same time, the humidity of the insulating layer has a great influence on its insulation performance. During the detection process, it is also necessary to test the insulation performance of the insulating layer under extreme humidity."

After the insulation of the wire disappears, a closed circuit can be formed between the power supply device, the conductor, the salt water, the wire and the connecting rod to enable the winding roller to generate magnetic force, thereby realizing the detection of insulation.

[0009] Under the above settings, when the present invention is used, the opening cover of the immersion box is opened, so that the wire passes through the slide cylinder and the outer side of the tensioning wheel from left to right in turn, and then is placed on the outer side of the winding roller.

[0061] Under the above settings, in order to prevent the loss of salt water during the detection process, the present invention further provides a feed pipe 4 for adding salt and water, and a salt content sensor 21 for detecting the salt content. The salt content in the salt water cannot be oversaturated to prevent the salt from being separated out and generating impurities in the water that affect the conductivity.

[0063] Under the above setting, after the winding roller 8 generates magnetic force, the present invention controls the upper shell 14 to move toward the winding roller 8, so that the iron block 35 comes into contact with the winding roller 8. After the contact, the upper shell 14 is controlled to move away from the winding roller 8. In the process of moving away, the tension spring 34 is continuously stretched until the iron block 35 is separated from the winding roller 8 again, and the reading of the tension sensor 33 at this time is read.

The activated carbon filter 41 can filter impurities in the process of the circulation of the salt water, reduce impurities, and ensure the conductive effect of the salt water;
