By reference to the accompanying drawings, configuration and principle of the present invention: a kind of based on geology detecting calibration cable, comprise by the conductor 1 of 19/0.16 multiply annealing tin-coated copper twisted wire, extrude F46 insulating barrier 11 outside conductor 1 and form into core 3 with tensile elements 2 mixing of at least three high strength aramid fibers, extrude urethane jacket layer 4 outside this one-tenth core 3, and equidistant L calibration ring 5 is set on restrictive coating 4; Restrictive coating 4 establishes outer diameter D, and ring 5 establishes internal diameter d, surface arranges redness or other marker color in calibration, and selects elastomeric material to make formation; In order to make calibration ring 5 increase with the adhesion of the coat layer of power cable 4, calibration ring 5 internal diameter d should be less than restrictive coating 4 outer diameter D, is interference fit; Select elastomeric material to make to form, the highly polished material processed in surface; Conveniently use, safeguard and change, open loop 52 sets the wide W of opening as 25 ~ 35mm, and angular aperture R ° is 35 ° ~ 45 °; The wide W of opening of the present embodiment open loop 52 is 30mm, and angular aperture R ° is 38 °; In order to improve certainty of measurement, calibration ring 5 presses L spaced set.
The present invention is achieved in that with reference to accompanying drawing, in order to the measurement requirement of the all-weather natural environment of applicable field geology situation, except cable must possess cold-resistant, resistance to daylight, outside humidity, the characteristic such as high temperature resistant; The pulling force that the geologic structure that simultaneously will overcome nearly hundred meters, below measuring distance earth's surface produces cable; In addition, also to get rid of silt, the impact that sandstone, magma, hydraulic pressure produce cable, therefore should consider reach normal use under the following conditions designing, when manufacturing this type of cable: a) rated voltage: exchange 500V and following; B) environment for use temperature :-40 DEG C ~+80 DEG C; C) environment for use: be applied in silt, in mudstone, magma, wetland or water; D) frequently bend; E) certain resistance to tension is possessed; F) there is positioning function; Therefore present embodiment adopts the multiply of 19/0.16 annealing tin-coated copper twisted wire to make conductor 1, the outer extruded insulation layer 11 of conductor 1; Insulating barrier 11 is selected and identical with polytetrafluoroethylene is fluoridized structure completely, and has the F46 resin of excellent thermoplastic process industrial art performance, and this F46 resin is one of high-end sciemtifec and technical sphere preferred material such as aerospace.
The present invention is achieved in that by shown in accompanying drawing, in order to solve the contradiction between calibration cable weight and flexibility, by the standard-required of calibration cable is: cable weight aspect should be more light better, and cable softness should be more soft better; If still continue to use traditional high-tensile steel wires to make tensile elements: one is the quality that can increase cable, and two is the flexibilities that can reduce cable; In addition, cable is in Long-Time Service, if steel wire fracture, the steel wire of projection can puncture insulation, causes short circuit; So the present invention considers to adopt and is different from traditional high strength aramid fiber yarn completely and makes tensile elements 2 and make tensile elements 2 with traditional high-tensile steel wires and carried out contrast test in development, and result of the test is as following table 1:
Table 1
| High strength aramid fiber | Cable high-tensile steel wires | |
| Tensile strength MPa | ≥2760 | 2000～2500 |
| Elongation at break % | ≤3.6 | ≥2.5 |
| Proportion g/cm3 | 1.44 | 7.8 |
Present embodiment selects high strength Du Pont KEVLAR 29 aramid fiber to make tensile elements 2, and tensile elements 2 adopts at least three symmetric arrays in stranding, is by pitch than 8 ~ 10 times of settings during stranding, and not band.
With reference to accompanying drawing, restrictive coating 3 selects polyurethane.It compares with conventional cable sheath material, and polyurethane material is soft, and proportion is little, have better resistance to wear, tensile strength is high, and oil resistance and water resistance can be splendid, and resist bending is tired, substantially not mildew, and extrude good processability, carry out without the need to special installation the feature of processing etc.; Realize the geological state detection instrument equipment on the safe and reliable ground that take place frequently for natural calamities such as earthquake, mud-rock flow, landslides of cable energy.
With reference to accompanying drawing, a kind of manufacture craft based on geology detecting calibration cable, its operating process is: wire drawing-zinc-plated-twisted wire-extruded insulation-stranding-simultaneously add tensile elements-extrude sheath-making to calibrate ring.Wherein, the stranding in operating process is by pitch than 8 ~ 10 times of settings, tensile elements 2 symmetric arrays wherein, and not band.
Key procedure in manufacture craft is as follows:
A, stranding/namely add tensile elements/operation, operation main points: pitch multiple proportions should control at 8 ~ 10 times simultaneously, tensile elements symmetry places arrangement wherein, and not band, in the gap of clamp-oning between stranding insulation to facilitate sheath material, reduce the slip between insulation and insulation.
B, making calibration ring
1. ring length allowance control is calibrated
Calibration cable needs makes a calibration ring every 500mm, to measure the geological state under different depth, for calibration ring, requires that tolerance is as following table 2:
Table 2
| Length (m) | Tolerance (mm) | Length (m) | Tolerance (mm) |
| 0～0.5 | ±2 | 0～5.0 | ±6 |
| 0～1.0 | ±3 | 0～10.0 | ±9 |
According to the margin of tolerance provided above, in the scope of 0 ~ 1.0m, tolerance can also control, if with every meter ± 3mm allowance control, due to the existence of cumulative errors, be accumulated to ± 15mm to its tolerance of 5.0m, seriously exceed the tolerance that 5 meters of long cables specify, therefore in order to reduce cumulative errors, by data analysis, we take following measure to control:
A) select precision instrument, reduce initial error;
B) by the allowance control of every 0.5 meter in the scope of 0.5mm;
C) after often completing 10 meters, adjustment initial error;
To taking measures above, latter made cable detects, and take up an official post at cable and get 20 meters, test data is as following table 3:
Table 3
The adhesion of 2. calibrating ring and sheath controls
Calibration ring is used to attached cable position, adhesion between it and sheath need be greater than the weight sum of cable its length weight and measuring instrument, principle is melted according to phase patibhaga-nimitta, by injection moulding process, calibration ring is tightly fixed on sheath, for ensureing the adhesion between it and sheath, following measure is taked to control
A) use anhydrous industrial alcohol wiping jacket surface before noting ring, remove the grieshoch of jacket surface, ensure the cleannes of jacket surface.
B) under the prerequisite fully ensureing polyurethane material melt flows, injection temperature is improved.
C) injection pressure is increased.
Fact proved, by taking above measure, calibration ring and sheath combine together, substantially increase the adhesion between it and sheath, after testing, each calibration ring can bear 50kg pulling force and not with sheaths separate.
With reference to accompanying drawing, a kind of application based on geology detecting calibration cable, from finished cable, selected one section of calibration cable is used as to detect arbitrarily, be an end points with any one calibration ring 5 in the calibration cable that this is selected and be fixed on testing stand, the other end hangs a weight and retention time 1-30min through pulley, measure weight and calculate its difference in height for twice, simultaneously on this section of selected calibration cable, peek comprises a detection segment for calibration ring 5, then measures the measurement tolerance of each detection segment respectively and get the mean value of its each measurement tolerance.
By reference to the accompanying drawings, calibration detection method is the every key property index of test cable, and by national Specification, the present embodiment only provides detection method to key property such as calibration ring length tolerance and adhesion etc.
