With the development of the times and the progress of science and technology, our household appliances are increasing, the demand for electric energy is also growing, the extension of lines is getting longer and longer, and the topology is getting more and more complex. The following is a method of making buried cable detection equipment.

Because underground cable laying does not take up space, most modern metropolises use buried cables instead of overhead cables, especially in residential areas, commercial areas, industrial areas and other places. Most modern metropolises use buried cables instead of overhead cables, which brings a lot of inconvenience to cable troubleshooting and capacity expansion.

In particular, the loss of design and construction drawings or the lack of relevant documents greatly increases the construction difficulty. This results in that once a fault occurs, the cable path and cable depth cannot be quickly determined, and the cable path and fault point cannot be quickly located. It often requires manual excavation in a large area, which is time-consuming and laborious. This paper mainly provides an underground cable detection equipment to solve the technical problems raised in the above background technology.

An underground cable detection device includes a transmitting module, a signal acquisition module, an information processing module, a microprocessor and a display module which are electrically connected in turn. The transmitting module includes a receiving box, the inside of which is fixed with a transmitter. A storage tank is formed between the transmitter and the inner wall of the receiving box. The signal acquisition module includes a connecting rod which is located inside the tank body of the storage tank, The bottom end of the connecting rod is fixed with a connector, and the first induction antenna and the second induction antenna are fixed inside the connector.

When using the detection equipment to measure the cable, first connect the cable to be tested with the transmitter 12 in the transmission module 1, so that the transmitter 12 outputs sinusoidal AC signals of 16 frequencies, and then hold the connecting rod 22 and the receiver 31 to move to the approximate installation area of the cable. Since the bottom end of the connecting rod 22 is fixed with the first inductive antenna 24 and the second inductive antenna 25 through the connector 23, When the first induction antenna 24 and the second induction antenna 25 are in the same plane and are kept perpendicular to each other, the first induction antenna 24 and the second induction antenna 25 are moved synchronously and horizontally. When the first induction antenna 24 and the second induction antenna 25 are directly above the buried cable to be measured, the received sinusoidal AC signal is strong; The signal received by the first inductive antenna 24 is the potential between the buried cable to be measured and the ground, and the signal received by the second inductive antenna 25 is the potential between the buried cable to be measured and the ground plus the potential between the first inductive antenna 24 and the second inductive antenna 25.
