Description

Technical Field

[0001] The present invention relates to the technical field of underground cable detection, and in particular to an intelligent detection device for underground communication pipeline cables. Background Art

[0002] Underground cable refers to the cable that is often buried underground compared with the common overhead line, so it is also called underground cable. The cable is made of one or more mutually insulated conductors wrapped with an insulating layer and a protective layer. It is used to transmit electricity or information from one place to another. After entering the modern society, due to the shortage of urban land, heavy traffic pressure, urban appearance construction and other reasons, large cities generally adopt underground cable transmission. Compared with overhead lines, cables have the advantages of small footprint, reliable transmission, and strong anti-interference ability.

[0003] The cable fault locator is an instrument that can detect the position of cables. Its principle is to send specific electromagnetic wave signals to underground pipelines. The detector uses the principle that when the probe is perpendicular to the ground plane of the magnetic field line, the received signal is minimum (almost zero) to determine the direction and depth of the buried cable. The existing detector is carried out by the cooperation of transmitter and receiver, and the operation process is usually to notify personnel to use handheld devices for detection, which has low work efficiency. In addition, the detection operation for different types of cables and pipelines is cumbersome and the degree of intelligence is low, which needs to be improved. Summary of the invention

[0008] Preferably, the driving end of the driving motor passes through the left side of the top end of the first detection vehicle and is fixedly connected to the middle of the top end of the gear, and the left side of the gear is threadedly connected to the middle of the right end of the threaded rod.

[0009] Preferably, a first drive motor is fixedly connected to the left side of the bottom end of the first probe vehicle, and the front and rear output ends of the first drive motor are connected to the first roller through connecting rods, and the right side of the bottom end of the first probe vehicle is also connected to the first roller through a connecting rod.

[0013] Working principle: When measuring a metal pipe with an exposed part, unplug the direct signal line connector from the grounding rod and connect it to the metal pipe with detection. Turn on the drive motor, which drives the gear to rotate and drives the threaded rod to move downward until it is inserted into the ground. Then turn on the electromagnetic signal transmitter and set the driving track of the second detection vehicle through PLC control. The second drive motor drives the second detection vehicle to start detection, and the steering motor controls its steering. When the target is detected, the signal receiver sends the signal data to the PLC control panel and calculates the specific position. At the same time, the PLC control panel controls the second detection vehicle to stop and sends a signal to the relay. The relay turns on the electromagnet, and the electromagnet attracts and moves the two magnetic contact metal sheets and touches the contact switches of the warning light and the buzzer respectively, triggering the buzzer and the warning light to light up to remind the inspector of the detection result. When detecting cables with exposed parts, clamp the clamp on the tested cable, and set the driving trajectory of the second detection vehicle through PLC control, and then repeat the above steps. When measuring metal pipes or cables without exposed parts, first let the second detection vehicle drive to the specified position, and then the first drive motor and the second drive motor respectively make the first detection vehicle and the second detection vehicle perform synchronous regular reciprocating motion, and repeat the above steps to detect the target.

[0014] The present invention provides an intelligent detection device for underground communication pipeline cables. It has the following beneficial effects:

[0015] 1. The present invention increases the intelligence of the detection process and reduces human participation by installing electromagnetic signal transmitters and signal receivers on the first detection vehicle and the second detection vehicle, and controlling them through a PLC control panel. The addition of a filter can make the detection results not only more accurate but also more efficient.

[0016] 2. The present invention can accurately measure metal pipes with exposed parts through the direct signal line on the first detection vehicle in conjunction with the grounding rod, and can accurately measure cables with exposed parts through the coupling line in conjunction with the clamp. The first detection vehicle and the second detection vehicle can cooperate to accurately measure metal pipes or cables without exposed parts, thereby increasing the applicability of the device. At the same time, through the cooperation of the electromagnet, the magnetic contact metal sheet and the contact switch, timely reminders can be made on the generation of detection results, which is convenient for detection personnel to view and record in time.

[0017] 3. When the second detection vehicle in the present invention encounters an uneven road surface during detection, the special structure formed by the alternating transformation of the tripod and the second roller can prevent the vehicle body from being lifted, but the tripod will flip, so that the second detection vehicle can move more smoothly, preventing the uneven ground from hindering the second detection vehicle, thereby increasing the convenience and accuracy of the detection process.
