Description
Technical field
The utility model relates to a kind of sucked type sensor, belongs to noiseless detection technique field.
Background technology
Ultrasound examination is one of large conventional sense method of five in field of non destructive testing, and it possesses the advantages such as environmental pollution is little, therefore in the internal discharge fault detect of power industry, is widely used.
What generally use both at home and abroad at present is the ultrasonic sensor based on piezoelectric effect.In the time that this ultrasonic sensor detects metal works, must fit tightly with detection faces, just can test the electric discharge sound of metallic walls inside.For this reason, existing conventional method is at ultrasonic probe position daubing coupling agent, and artificially exerts oneself by being pressed in test department position in the time detecting.But artificial shake or slide all can to detect effect impact, even flood the discharge signal of metallic walls inside.If the detection faces of tested metallic walls is more coarse, this detection method can not meet testing requirement; In addition,, in the time that the snap-in force of popping one's head in is larger, probe also may be damaged in the surface that tested metallic walls is coarse.Therefore, provide one to be applicable to difform, the ultrasonic sensing device tool of the detection faces of different smooth degree is of great significance.
Utility model content
In order to overcome above-mentioned detection defect, the utility model provides a kind of sucked type sensor.It not only has better Measurement sensibility, has extended the serviceable life of probe, and because improved the test mode of probe, makes it have better Effect on Detecting.
To achieve these goals, the utility model adopts following technical scheme:
A kind of sucked type sensor, comprises pedestal, spring assembly, probe and sucker; Wherein, described probe is embedded in spring assembly, and described spring assembly is embedded in pedestal; Described sucker is laid in spring assembly around and is fixedly arranged on base-plates surface, and its surface keeps same level with detecting head surface.
Wherein, many groups spring that described spring assembly comprises draw-in groove and is connected with its bottom; Described probe is embedded to be fixed in the draw-in groove suitable with its profile.And a socket is established in draw-in groove below, passes for the signal-transmitting cable of popping one's head in.
Described spring is fixedly arranged in pedestal, and is connected with draw-in groove bottom.
Described number springs can arrange according to actual needs, conventionally preferred 2-4 group.
Described sucker is made by having adsorptive power elastomeric material, to meet the absorption demand to metallic walls in practical application.
Described sucker number is advisable with 3-6, and preferably 3, and be evenly distributed on base-plates surface with circular pattern, and make its suction more well-balanced, be more suitable for the detection that outer wall is the metal device of arc.In the time detecting the GIS switch cubicle outer wall of metallic walls, particularly arch of surface irregularity, sucker can steadily adsorb in its surface, is conducive to the work of sensor.
While using sucked type sensor described in the utility model, first sucker and probe are pressed down simultaneously, sucker is adsorbed in metal outer wall, due to the existence of absorption affinity, spring will Partial shrinkage, thereby makes probe be fixed on metal outer wall surface; Due to the existence of spring assembly, no longer there is shake or sliding phenomenon in probe, in whole testing process, no longer needs artificial control probe positions, not only reduce conventional ultrasound probe suffered outside noise in the time detecting and disturb, also reduced people for pressing the unstable detection error of bringing.
Sensor described in the utility model, its probe can not deform and move in testing process, has better Measurement sensibility, has extended the serviceable life of probe, and because improved the detection mode of probe, makes it have better Effect on Detecting.In addition,, because described sensor does not need to change the structure of original probe, be applicable to all kinds of ultrasonic probes.

In figure: 1 pedestal, 2 suckers, 3 spring assemblies, 4 probes, 5 draw-in grooves, 6 springs, 7 signal-transmitting cables, 8 chuck surface, 9 sucker bottoms.
Embodiment
Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
Embodiment 1
A kind of sucked type sensor, as shown in Figure 1, comprises pedestal 1, spring assembly 3, probe 4 and sucker 2; Wherein, described probe is embedded in spring assembly, and described spring assembly is embedded in pedestal; The bottom 9 of described sucker is fixedly arranged on base-plates surface and is laid in around spring assembly, and chuck surface 8 keeps same level with detecting head surface.
Wherein, described spring assembly 3 comprises draw-in groove 5 and coupled many groups spring 6; Described probe is embedded to be fixed in the draw-in groove suitable with its profile.And a socket is established in draw-in groove below, passes for the signal-transmitting cable 7 of popping one's head in.
Described spring is fixedly arranged in pedestal, and is connected with draw-in groove bottom.
Number springs is 2 groups.
Described sucker is made up of elastomeric material, and described sucker number is 3, and is evenly distributed on base-plates surface with circular pattern, makes its suction more well-balanced, and in the time detecting the GIS switch cubicle outer wall of arch, chuck surface 8 can steadily be adsorbed in its surface.
To detect GIS switch cubicle as example, while using sucked type sensor described in the utility model, first sucker and probe are pressed down simultaneously, sucker is adsorbed on GIS switch cubicle curved metal wall surface, due to the existence of absorption affinity, spring section compression, thus make probe be fixed on GIS switch cubicle curved metal wall surface, and testing staff is without sensing station manually being adjusted again.After detection finishes, one side of sucker is opened, allow air enter and can take sucked type sensor.
Although, above with a general description of the specific embodiments the utility model being done to detailed description, on the utility model basis, can make some modifications or improvements it, this will be apparent to those skilled in the art.Therefore, these modifications or improvements on the basis of not departing from the utility model spirit, all belong to the claimed scope of the utility model.
