Description
Technical Field
The utility model relates to a relevant technical field of magnetotelluric appearance. More specifically, the utility model relates to a magnetotelluric appearance cable fault detection device.
Background
An EH4 continuous conductivity profiler (EH 4 for short) is a magnetotelluric instrument and is widely applied to the fields of engineering investigation, resource investigation and the like, and the EH4 system comprises: the main machine, the preamplifier, the electric track electrode, the magnetic sensor, the connecting cable and the like, wherein the connecting cable comprises 2 cables (magnetic track lines for short) for connecting the preamplifier and the magnetic sensor, and 1 cable (main control line for short) for connecting the main machine and the preamplifier. Both are integrated multi-core cables, the magnetic track line is 8 cores, the main control line is 15 cores, and both ends of the cable are respectively provided with a male connector and a female connector.
In the investigation operation, because the cable often needs to be coiled and bent, the probability that the cable is damaged mechanically is the largest in the whole set of the instrument. About 80% of the failure cases are due to wire core breakage or poor contact in the cable. Therefore, when a fault of unknown cause is encountered in field work, it is first checked whether the cable is normal. Since the multi-core cable is more easily damaged, the track wire and the main control wire become key inspection objects. The cable inspection mainly comprises the following steps of inspecting whether each wire core in the cable is broken or not: set up the ten thousand logical meters into measuring the break-make gear, with the both ends of a certain sinle silk in two meter pens simultaneous test cables of universal meter (the contact pin of the public mouthful of joint of cable and the socket of female mouthful joint), if the sinle silk route, then the universal meter sends buzzing sound, if the universal meter does not have the reaction, then explains that the sinle silk has the place of opening a circuit, has damaged. The above inspection method has the following drawbacks:
1. for the master control line, the cable includes 15 cores, but 19 pins are provided on the male panel of the cable (the same principle applies to the female panel). In the 19 pins, 10 pins are respectively connected with the 10 wire cores in a one-to-one correspondence manner; 3 contact pins are connected corresponding to the 1 wire core; 2 pins are left empty and are not connected with the wire core; and 4 contact pins and 4 wire cores are divided into 2 groups, and 2 contact pins and 2 wire cores in each group are in a cross parallel state. The arrangement condition of the wire cores is relatively complex, and an inspector needs to be familiar with the cable and can be competent for inspection tasks only with certain working experience.
2. The magnetic track line and the main control line all belong to the higher cable of integrated level, and the magnetic track line has set up 8 pieces of contact pins (socket) on the circular interface panel of diameter 1.4 centimetres, and the main control line has set up 19 pieces of contact pins (socket) on the circular interface panel of diameter 2 centimetres, and the panel space is narrow and small, and the inspection work is difficult to be carried out, needs the inspection personnel to have higher hand-manipulating ability just can accomplish the inspection.
3. In order to mark the position, the contact pin and the socket side printing belonging to the same wire core on the interface panels at the two ends of the cable are printed with the same English letters. In long-term use, the cable connector is continuously plugged, and English letters printed on the panel are worn out or even completely disappeared. Whether the checked contact pin and the socket belong to the same wire core or not is difficult to accurately judge during checking, and misjudgment and missed judgment are easily caused.
4. Need the inspection personnel to hold the cable joint on one hand during the inspection, test with universal meter pen-shape metre on the other hand, consequently, when inspection cable both ends connect, 1 people can't accomplish, needs 2 people concurrent operation, and is very inconvenient.
5. As for the female connector of the cable, the number of the wire cores is large, the space of the connector panel is small, the socket on the female connector is thin and deep, and the conventional multimeter pen needle is too thick to go deep into the socket for inspection. The conventional multimeter pen can only be modified (a section of thin iron wire is welded on the pen), and then the inspection work is carried out, so that the workload is increased.
