Abstract
The invention discloses a kind of depth detecting instrument of house crack fracture after earthquake hazard, comprise reel, probe, vibration exciter, power supply, casing, cover plate, knob, switch, wherein, cover plate is positioned at the casing upper end, and switch is positioned at the casing side, and a hole is arranged at the casing bottom; Vibration exciter, power supply, reel are fixed on the casing inner wall, and vibration exciter provides shaking force, and power supply provides power for vibration exciter; Probe is made of metal thin rod shape, has elasticity and toughness, and the one end is fixed and is crimped onto on the reel, and the other end stretches out from the hole of casing bottom; Knob links to each other with the reel axle center, props up for outside the casing, is used to reply probe.In addition, the connection of vibration exciter, power supply, switch belongs to general knowledge, repeats no more here.The present invention is simple in structure, does not need extraneous power supply, and is easy and simple to handle during use, is applicable to in-site measurement.
Description
Technical field
The present invention relates to a kind of detector, especially the depth detecting instrument that when measuring house crack fracture after earthquake hazard, uses.
Background technology
Industry and various base plates, wall, top board and the underground box foundation of civic building and hole and the crackle that other special structure houses all may run into different shape, as circle, square, rectangle or the like.Also have some structures to meet the situation of the abrupt change of cross section at length direction.Particularly,, cause the crack because the strong destruction of seismic event at hole and tapered rotation angle position, can cause that also stress is concentrated after the earthquake; On the other hand, the shatter resistant degree of house when building is little, even if do not have hole and crackle, also can ftracture owing to the strong building intensity that surpasses the house of seismic event.Therefore, after the earthquake, the crack takes place in the house is common phenomena.How after the earthquake, the crack in house being detected, is the primary work of assessment house damage situations, has crucial meaning for reducing the secondary injury.
Chinese patent CN1556399 number disclosed " crack of construction digital measuring apparatus " patent (application number: 200310122005.3), comprise light source, imaging device and digital image unit, the digital image unit is made up of power supply and the digital image pickup that is connected with power supply, data processing unit, LCD, data storage cell and communication interface; Imaging device is made up of imaging lens and lens barrel; Digital image pickup is used to obtain image and is converted into digital image signal; Data processing unit is made up of DSP and CPU, DSP be used for to digital image signal gather, processing etc.; The CPU storage inside has Control Software, is used for each building block of described digital image unit is operated control; Data processing unit through data line is connected with described image sensor, LCD, data storage cell and communication interface respectively.Chinese patent CN2723960 number disclosed " distress in concrete sounder " patent (application number: 200420016797.6), form by parts such as transmitting and receiving transducer, electronic switch, programmable amplifier, buffer rcgister, analog to digital converter, mission controller, selection control, power supply; When this utility model need not measured the concrete velocity of sound and stride the sound in crack, it adopted a plurality of transducers that transmit and receive to transmit and receive a plurality of acoustic signals successively, and utilized the phase change of measuring point directly to calculate the degree of depth that determines tested crack.The weak point of these two patents is: can judge the buildings crackle, and fracture parameters is measured, obtain the depth parameter of crackle, but complex structure, operation inconvenience is had relatively high expectations to environmental baseline during use, is not suitable for in-site measurement.
Summary of the invention
Purpose of the present invention is exactly the depth detecting instrument that a kind of house crack fracture after earthquake hazard simple in structure will be provided, and makes it can in time operate in-site measurement in use.
In order to achieve the above object, the depth detecting instrument of house crack fracture after earthquake hazard provided by the invention comprises reel, probe, vibration exciter, power supply, casing, cover plate, knob, switch, and wherein, cover plate is positioned at the casing upper end, switch is positioned at the casing side, and a hole is arranged at the casing bottom; Vibration exciter, power supply, reel are fixed on the casing inner wall, and vibration exciter provides shaking force, and power supply provides power for vibration exciter; Probe is made of metal thin rod shape, has elasticity and toughness, and the one end is fixed and is crimped onto on the reel, and the other end stretches out from the hole of casing bottom; Knob links to each other with the reel axle center, props up for outside the casing, is used to reply probe.In addition, the connection of vibration exciter, power supply, switch belongs to general knowledge, repeats no more here.When the present invention uses, to open switch and make vibration exciter work, probe progressively gos deep into to fracture, till can not going deep under the effect of shaking force; Take off this detector measuring probe extension elongation, can detect the degree of depth of crack fracture, and knob can be replied probe.
The depth detecting instrument of house crack fracture after earthquake hazard provided by the invention has positive effect: comprise reel, probe, vibration exciter, power supply, casing, cover plate, knob, switch, and simple in structure, do not need extraneous power supply; Easy and simple to handle during use, be applicable to in-site measurement.
Description of drawings
The present invention will be further described in conjunction with the accompanying drawings, please referring to accompanying drawing:
Accompanying drawing 1 expression synoptic diagram of the present invention.
Structure shown in the accompanying drawing 1 comprises: cover plate 1, vibration exciter 2, power supply 3, probe 4, switch 5, knob 6, reel 7, casing 8, hole 9.
Embodiment
The depth detecting instrument of house crack fracture after earthquake hazard provided by the invention comprises reel 7, probe 4, vibration exciter 2, power supply 3, casing 8, cover plate 1, knob 6, switch 5, wherein, cover plate 1 is positioned at casing 8 upper ends, and switch 5 is positioned at casing 8 sides, and a hole 9 is arranged at casing 8 bottoms; Vibration exciter 2, power supply 3, reel 7 are fixed on casing 8 inwalls, and vibration exciter 2 provides shaking force, and power supply 3 provides power for vibration exciter 2; Probe 4 is made of metal thin rod shape, has elasticity and toughness, and the one end is fixed and is crimped onto on the reel 7, and the other end stretches out from the hole 9 of casing 8 bottoms; Knob 6 links to each other with reel 7 axle center, props up for outside the casing 8, is used to reply probe 4.In addition, the connection of vibration exciter 2, power supply 3, switch 5 belongs to general knowledge, repeats no more here.When the present invention uses, to open switch 5 and make vibration exciter 2 work, probe 4 progressively gos deep into to fracture, till can not going deep under the effect of shaking force; Take off this detector measuring probe 4 extension elongations, can detect the degree of depth of crack fracture, and knob 6 can be replied probe 4.
Protection domain of the present invention relates to all changes form recited above.
