Abstract
The invention provides a telescopic type watertight electric probe sensor for an underwater explosion test. The watertight electric probe sensor is characterized in that the sensor comprises a twisted pair enameled wire, a thin casing tube, and lead wires. One end of the twisted pair enameled wire is respectively welded with the two lead wires and is connected to measuring equipment and the other end is in an open circuit state. The thin heat-shrinkable casing tube with the minimum diameter is sleeved outside the twisted pair enameled wire; and the two ends of the casing tube exceed the enameled wire by 1 centimeter. The two ends of the thin casing tube are sealed, thereby realizing the impedance matching effect. The following beneficial effect is realized: the application range of the probe sensor can be expanded to the deep seawater environment.
Description
Technical field
The present invention relates to a kind of water shooting test electricity consumption probe sensor, especially a kind of bushing type watertight electric probe sensor that can use in 40 meters of dark briny environments.
Background technology
During marine explosive test, owing to being subject to impact and the quick-fried source of ocean current can not adopt rigidity to lay mode, cause laying marine quick-fried source and easily produce drift.How accurately the blast instantaneous space position in the quick-fried source movement of test is the key issue in test, directly has influence on the assessment of brisance.Adopt and commonly take underwater acoustic technology and be unsuitable for measuring the instantaneous locus of blast as basic target following technology, adopting Shock Wave Time Difference is more feasible way.Principle of work [the marine technology of shock wave time difference method of testing, 2003,22 (2): 28-33] be when pasting blast zero on quick-fried source triggering collection contact and by test to quick-fried source instantaneous explosion signal be multiplied by with the time difference that measuring point produces pressure signal the distance that the marine velocity of propagation of shock wave obtains measuring point and the quick-fried heart, by laying multichannel measuring point battle array and carry out matching and resolve the accurate locus that obtains the quick-fried heart.
At present, domestic while carrying out water shooting zero triggering collection measuring point by piezoelectric effect and detecting probe method, realize.Some dielectric crystal, when its tension stress, compressive stress or shearing stress are done the used time, except producing corresponding strain, also in crystal, induce dielectric polarization, cause crystal two end surfaces to occur the bound charge that symbol is contrary, its electric density is directly proportional to external force, this do not have an electric field action, the phenomenon that is made dielectric crystal produce polarize by the effect of mechanical stress and form plane of crystal electric charge is exactly piezoelectric effect [material property, publishing house of Beijing University of Technology, 2004].Piezoelectric ceramics is the piezoelectric [new material outline, National Defense Industry Press, 2004] of widespread use, and when water shooting is zero, signals collecting also more generally adopts piezoelectric ceramic piece.The electric density producing due to piezoelectric ceramics is directly proportional to external force, and the contact that is pasted on quick-fried source can be subject to the impact that explosion time can produce tens thousand of atmospheric pressures, and the voltage that contact produces is larger, directly affects the safe and reliable work of test macro.
When quick-fried source is zero, the signals collecting electrical resistivity survey skill of handling needles is a kind of passive touch sensor in itself, during work, need impressed voltage, when detonation wave, shock wave and film flying etc. reach electric probe place section, electric probe on off state is undergone mutation, send an of short duration pulse signal, can be used as " switch " of the high-speed motions such as explosive detection detonation.Have simple in structure, easy to make, the advantages such as reliable in action.In blast and impact process, for recording blast initial time record, measure the conventional electrical resistivity survey skill of handling needles of test macro of detonation wave speed, shock velocity constant duration as signal acquisition means.
Impedance between two enameled wires of probe requirement of being made by two multiple twin enameled wires reaches 20k Ω and could realize, and can in air and fresh water pond, give full play to its effect.But in the degree of depth, reach in the seawater of 40 meters of left and right, the impedance between two-way probe wire is only 7k Ω, and the effect of probe can be affected, and even occurs the situation of glitch.Must manage to solve watertight problem under the prerequisite that does not affect probe function, to adapt to the briny environment of Low ESR, the large degree of depth for this reason.
Summary of the invention
For guaranteeing to solve watertight problem under the normal prerequisite of using of electric probe, adapt to the briny environment of Low ESR, the large degree of depth, the invention provides a kind of bushing type watertight electric probe.Described bushing type watertight electric probe is taked in the additional thin sleeve pipe of electric probe sealed at both ends method, and through repeatedly testing in 40 meters of depth of water seawater, in the time of can realizing blast zero, signal obtains.
The technical solution adopted in the present invention is: a kind of bushing type watertight electric probe for water shooting test, it is characterized in that: described bushing type watertight electric probe comprises multiple twin enameled wire, thin heat-shrinkable T bush, wire, wherein multiple twin enameled wire one end respectively with two wire bonds; Thin heat-shrinkable T bush is enclosed within outside multiple twin enameled wire; Thin heat-shrinkable T bush two ends should exceed 1 centimetre, enameled wire; Thin sleeve pipe is sealed at both ends.Its annexation is: multiple twin enameled wire one end respectively with two wire bonds, and be connected to measuring equipment, other end open circuit; Thin heat-shrinkable T bush is enclosed within outside multiple twin enameled wire, and thin heat-shrinkable T bush is sealed at both ends.
