Description

One kind blast cut test device

Technical field

The utility model is related to blast cut testing field, and in particular to one kind blast cut test device.

Background technology

To the damage measure of Blast Loads lower body, it usually needs it is determined that blast cut scope and specific damage position Put.At present, existing method of testing has two kinds, and one is that after explosive test, test plate body is departed from from testing machine, then carries out Observation test, and then obtain break location information.Two be to paste foil gauge, detection test plate body material strain feelings in test zone Condition.However, the former test error is larger, the workload of experiment and detection is larger, and operating technology difficulty is higher.The latter then operates Difficulty is big, once occurring cut or fracture transmission signal will interrupt, adds the complexity of test, and this kind of mode is aligned Confidence breath is not sensitive enough, is unfavorable for immediately arriving at the positional information of cut and damage.

Utility model content

The purpose of this utility model is to provide a kind of blast cut test simple in construction, can measuring blast break location Device.

The technical solution adopted in the utility model is：

One kind blast cut test device, including test plate body, test cell, display；The test plate body is divided Into multiple test zones；Test cell is equipped with each test zone, i.e., each test cell is arranged in parallel, and is not interfere with each other；Institute Stating test cell includes power supply, wire, sensor, and one end of wire is connected with power supply, and the other end of wire is connected with sensor, Power supply is connected with sensor, and the laying in wave shape of the wire in test zone is paved with whole test zone, sensor collection wire Signal after, then the signal transmission shown to display.

Test plate body is first carried out subregion by the utility model, to carry out subregion domain test；Uniformly led in each subregion Line, wire one sensor of correspondence in each region, sensor is connected with wire；Sensor gathers the conductor signal in the region, And shown the signal transmission to display.When being tested, test plate body is subjected to impact, when some subregion is broken During mouth, it is ensured that with the deformation of test plate body respective change occurs for wire, i.e., when cut occurs in test plate body, the subregion Wire fracture, current interruptions in circuit, now, display shows that the magnitude of voltage in the region is undergone mutation, the voltage jump area Domain is explosion cut region.

By such scheme, line channel is provided between adjacent test zone, in order to guide wire, makes entirely to test plate body Seem attractive in appearance, also allow for installing for wire.

By such scheme, the blast cut test device also includes integrated box, all wires come out from test plate body It is connected again with sensor into integrated box, to solve, wire is more, the in disorder problem of the circuit caused.

By such scheme, the waveform is square, in order to connect up；Can certainly be other waveforms, as long as to the greatest extent can may be used Subregion can be uniformly paved with.

By such scheme, the test plate body is divided into uniform test zone, fast and accurately to draw cut Position.

The beneficial effects of the utility model are：

Measurement circuit is built by power supply, wire etc., occurred corresponding with the change of test plate body using measurement circuit Change, the signal of sensor collecting test circuit so as to accurately draw break location, reduces work difficulty, improves detection Precision；

Without other detection devices, it only need to be that can reach testing goal using the signal intensity in circuit, operate very simple It is single；

Without being dismantled to test plate body, simple and reasonable, feasibility is high, and security is good, practical.

Brief description of the drawings

Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing：

Fig. 1 is the structural representation of the utility model blast cut test device；

Wherein：1st, plate body is tested；2nd, wire；3rd, line channel；4th, integrated box；5th, sensor；6th, display.

Embodiment

In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain this Utility model, is not used to limit the utility model.

Referring to Fig. 1, one kind blast cut test device, including test plate body 1, test cell, display 6.Test plate body 1 It is divided into multiple uniform test zones（That is area and shape is essentially identical）.It is single that test is equipped with each test zone Member, i.e., each test cell is arranged in parallel, and is not interfere with each other.Each test cell is a measurement circuit, and it includes power supply, wire 2 With sensor 5, one end of wire 2 is connected with power supply, and the other end of wire 2 is connected with sensor 5, and power supply is connected with sensor 5. Wire 2 in test zone is laid in square wave, is paved with whole test zone.After the signal of the collection wire 2 of sensor 5, then will The signal transmission is shown to display 6.Line channel 3 is provided between adjacent test zone（It is horizontal and vertical be all provided with it is wired Paths 3）, in order to guide wire, whole interface is seemed more attractive, also allow for installing for wire 2.

In the utility model, all wires 2 come out from test plate body 1 are concentrated into integrated box 4, then with sensor 5 connections, to solve, wire is more, the in disorder problem of the circuit caused.

Operation principle is：, can the generation damage or broken under load effect when testing the impact of the experience of plate body 1 or strong load Mouthful.When testing plate body generation cut, the circuit in the region can be destroyed, i.e. signal interruption, and electricity can be presented over the display Pressure mutation, obtains corresponding voltage Sudden change region and may know that corresponding cut region.

Because regular arrangement is presented in circuit, and it is easy to get to test each zone position information of plate body, therefore is readily available brokenly Mouth positional information.

It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted, And all these modifications and variations should all belong to the protection domain of the utility model appended claims.
