Abstract
The utility model discloses a hardware fitting fatigue damage detection apparatus which is characterized by comprising an ultrasonic detection module for emitting and receiving ultrasonic signals; a display screen module for displaying reflected waves inside detected hardware fittings; an ultrasonic data processing module for determining amplitudes of the reflected waves inside the hardware fittings detected by the ultrasonic detection module; an alarm module; and a high-definition video camera shooting module.
Description
Technical field
The utility model belongs to electrical equipment technical field, relates to a kind of gold utensil fatigue damage sniffer, and this device is applicable to power transmission line is carried out remote monitoring.
Background technology
Send electric wire widely used iron or aluminum metal-ware, be referred to as gold utensil.Gold utensil is of a great variety; purposes is different; for example; the various wire clamps that conducting wire is used, the various links of composition insulator chain, various aluminium hydraulic pressed connecting pipes, the repair sleeve of connection wire; various types of conductor spacers on the split conductor etc.; all kinds of metal parts of pull wires that also have shaft tower to use in addition, and relevant as the size of guardwire, must work in coordination.
Most of gold utensil is in operation and need to bears larger pulling force, and what have will guarantee simultaneously that also the contact of electric aspect is good, and it is concerning the safety of wire or shaft tower, even a damage also may cause line fault.Therefore, the quality of gold utensil, correctly use and install, send electricity to have a significant impact to the safety of circuit.
Because the transmission line of electricity long term exposure is in the open air, gold utensil connects complicated, and kind is more, the erosion of the environment such as wind-engaging, heavy rain, and the hidden danger of often burying after the gold utensil fatigue is difficult for finding that therefore the lesson of gold utensil fracture accident is often arranged.
Therefore, this area is needed a kind of instrument that can detect simple and easy, easily power transmission line gold utensil fatigue damage degree badly, and it can in time find the tired hidden danger of gold utensil, in time safeguards the accident of avoiding.
Summary of the invention
The utility model patent is a kind of gold utensil fatigue damage sniffer, can scan at a distance, finds and detection gold utensil degree of fatigue, in time changes, and improves the line security operation level.Described device comprises with lower member: the ultrasonic listening module, and emission and received ultrasonic signal, when needs detected gold utensil, the gold utensil emission ultrasound wave that the ultrasonic listening module at first detects to wish received this hyperacoustic echo subsequently; Display panel module is used for showing the reflection wave that is detected gold utensil inside that horizontal ordinate is time shaft, and ordinate is amplitude axis; The ultrasound data processing module is used for judging that the amplitude of the detected gold utensil inner counter of ultrasonic listening module ejected wave is big or small, has metal fatigue damage if this reflection wave, is then judged this gold utensil inside greater than a predetermined threshold; Alarm module links to each other with the ultrasound data processing module, comprises alarm lamp and alarming horn, and after the ultrasound data processing module was judged the inner existence damage of gold utensil, alarm module was sounded, the light alarm; High-definition camera instrument photo module links to each other with the ultrasound data processing module, after the ultrasound data processing module is judged the inner existence damage of gold utensil, is used for the gold utensil internal reflection waveform that display panel module shows is taken.。
Description of drawings
Fig. 1 is gold utensil fatigue damage sniffer of the present invention system composition diagram.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to restriction of the present utility model.
The metal fatigue damage sniffer, mainly utilize ultrasonic reflection effect and penetration power strong, generally in uniform material, the existence of defective will cause the discontinuous of material, this discontinuous the inconsistent of acoustic impedance of often causing again, we know by reflection theorem, ultrasound wave will reflect on the interface of the medium of two kinds of different acoustic impedances, the difference of the size of the energy that reflects and interface both sides medium acoustic impedance and the orientation of interface, size is relevant, after the ultrasound wave of emission runs into this interface, will reflect, the energy that reflects is received by probe again, certain position of horizontal ordinate will show the waveform of a reflection wave in display screen, and this position of horizontal ordinate is exactly the degree of depth of defective in detected material, and ordinate is the amplitude of ultrasonic reflections ripple.The height of this reflection wave and shape have reflected the character of defective because different defectives is different, and by the high precision camera lens viewed defect record are got off.
As shown in Figure 1, gold utensil fatigue damage sniffer comprises such as lower member: ultrasonic listening module, display panel module, ultrasound data processing module, alarm module and high-definition camera instrument photo module.
The ultrasonic listening module can be launched and received ultrasonic signal, and when needs detected gold utensil, the gold utensil emission ultrasound wave that the ultrasonic listening module at first detects to wish received this hyperacoustic echo subsequently.
Display panel module is used for showing the reflection wave situation that is detected gold utensil inside.Horizontal ordinate is time shaft, and the residing horizontal ordinate of reflection wave has represented and produced reflection wave also is the position of gold utensil internal injury, and the horizontal ordinate that reflection wave is positioned at is larger, and then the position of representative damage appearance is darker; Ordinate is amplitude axis, and the residing ordinate of reflection wave represents the order of severity of gold utensil internal injury, and the ordinate of reflection wave is larger, and then the representative damage is more serious.
The ultrasound data processing module is used for judging that the amplitude of the detected gold utensil inner counter of ultrasonic listening module ejected wave is big or small, has metal fatigue damage if this reflection wave, is then judged this gold utensil inside greater than a predetermined threshold.Original amplitude of ultrasonic size, metal species that the setting of threshold value and ultrasonic listening module send have relation, and original amplitude of ultrasonic is large, and then threshold value also increases accordingly.
Alarm module links to each other with the ultrasound data processing module, can comprise alarm lamp and alarming horn, and after the ultrasound data processing module was judged the inner existence damage of gold utensil, alarm module was sounded, the light alarm, reminds the testing staff to overhaul.
High-definition camera instrument photo module, link to each other with the ultrasound data processing module, after the ultrasound data processing module is judged the inner existence damage of gold utensil, be used for the gold utensil internal reflection waveform that display panel module shows is taken, so that staying shelves preserves, perhaps send to remote control center, in order to data are further analyzed.
Gold utensil fatigue damage sniffer described in the utility model can be made very little device, overhauls so that the field work personnel are hand-held.With low cost, easy to operate.
Above-described embodiment is more preferably embodiment of the utility model, and the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacement all should be included in the protection domain of the present utility model.
