A buried cable search device and method

Abstract

The invention provides a buried cable search device, which includes an inverted U-shaped mobile frame, a shielding cylinder, a rotating motor, a search mechanism, and a paint-spraying marking mechanism. The search mechanism includes a rotating plate, a main control unit, and a first The transceiver and the second transceiver and the third transceiver used to send and receive low-frequency electromagnetic waves move the inverted U-shaped mobile frame to the area to be searched, obtain the initial position of the cable through the first transceiver, and then drive the rotating plate to rotate through the rotating motor , so that the second transceiver and the third transceiver are located above the buried cable at the same time, the main control unit controls the inverted U-shaped mobile frame along the connection direction of the second transceiver and the third transceiver, and uses the second transceiver as the front end When moving, the paint marking mechanism is used to spray paint on the ground while moving, so as to realize the automatic search of the position and path of the buried cable, which can reduce the labor intensity of the staff.

Description

technical field [0001] The invention relates to the technical field of power cable maintenance, in particular to a buried cable search device and method. Background technique [0002] Power cables are the most basic components used in the power system, which play the role of transmitting and distributing electrical energy. Power cables will be damaged in long-term use. Therefore, it is necessary to regularly repair, maintain or replace power cables. For the cable, it includes the overhead line part and the buried part. The overhead line part is a visible cable because it is laid on the tower, and its maintenance can be judged by common maintenance instruments. , For invisible cables, due to the different environments in different regions, the location and direction of buried cables are often irregular, which provides a greater obstacle to the search for buried cables. At present, most of the searches for buried cables are It is the maintenance personnel who carry out a larg...

[0002] The power cable is the most basic part of the power system, which plays the role of transmitting and distributing electric energy. The power cable will be damaged during long-term use. Therefore, it is necessary to regularly overhaul, maintain or replace the power cable. For power As far as the cable is concerned, it includes the overhead line part and the buried part. Because the overhead line part is laid on the iron tower, it is a visible cable. Its maintenance can be judged by commonly used maintenance instruments. , for invisible cables, due to the different environments in different regions, the location and direction of buried cables are often irregular, which provides a large obstacle for the search of buried cables. At present, most of the searches for buried cables are It is maintenance personnel who carry out large-scale inspections on the ground with instruments. The entire cable search process takes a lot of time, especially in areas with complex underground terrain. After finding the location of the cable, it is generally along the line where the cable is Find the direction of the cable. However, there will be a curved part of the buried cable. When the staff searches for the cable along a straight line and reaches the curved part, the position of the cable will be lost. At this time, the cable position needs to be searched again. The instrument does not have a marking function, and it is easy to forget the location and path of the cable that was originally found after searching for cables in a large area
