Abstract
The invention relates to an integrated device of an earth space vibration acquirer. The integrated device is arranged on the earth surface and used for fixing vibration sensors and sampling earth vibration. The integrated device comprises a bottom plate (100) and a vertical plate (200) which is fixedly connected to a steel angle. Two orthogonal vertical faces (210 and 220) of the vertical plate are provided with screw holes respectively used for fixing a first sensor (310) and a second sensor (320). An area, enclosed by the two vertical faces (210 and 220), on the bottom plate (100) is also provided with a screw hole used for fixing a third sensor (330). Nail holes (101, 102, 103 and 104) are respectively arranged in four corners of the bottom plate (100). The integrated device of the invention is convenient to install and disassemble and better protects the sensors. The experiment time can be saved, earth space vibration testing in three directions can be easily realized, and the test efficiency is improved.
Description
Technical field
The invention belongs to ambient vibration field of test instrument, relate in particular to the integrating device technical field of the earth three dimensions vibration acquisition device.
Background technology
Because violent earthquake dynamic sensor all can only be tested a direction, therefore in the prior art, still there is no to test the sensor of the earth three dimensions vibration simultaneously.A kind of practical method is exactly that the vibration transducer of three directions is integrated on an object, can gather the vibration of three directions simultaneously.But, at present conventional integrating device or carry inconvenient cast-in-place concrete piece, or disposable use and the poor plastic body of fixed mass, then with the poisonous chemical materials such as AB glue by sticky the sensor of three directions thereon.Facts have proved in a large number, these article are not only installed complexity, inefficiency, and cause a large amount of waste of material and environmental pollution.
2, the objective shortcoming of prior art (one or more shortcomings that can solve or improve by this patent):
1) existing apparatus is all disposable, does not meet reusable principle, causes the waste of resource.
2) installation process complexity, inefficiency.
3) installation leveling precision is not high, and experimental error is larger.
4) the dismounting inconvenience of the sensor after gluing, and unloading process easily damages sensor, reduces the serviceable life of sensor.
Summary of the invention
In view of the above shortcoming of prior art, the object of this invention is to provide a kind of integrating device of the earth space oscillations collector, make it to overcome the above deficiency of prior art.
The means that realize the object of the invention employing are:
An integrating device for the earth space oscillations collector, is arranged on the fixing and earth shock sampling of earth's surface for vibration transducer, and integrating device is by base plate 100 and be connected in angle steel riser 200 and form.On orthogonal two facades (210 and 220) of riser, be provided with the screw for fixing respectively first sensor 310 and the second sensor 320; On base plate 100, be subject to two facades (210 and 220) to surround region and be also provided with the screw of fixing the 3rd sensor 330; Four jiaos of base plate 100 are provided with nail hole (101,102,103 and 104).
The maximum feature of apparatus of the present invention is not use the chemical material fixation of sensor such as AB glue, but by the mode of prepared screw-bolt hole on integrating device, vertical and level are fixed by bolts on it to sensor, then use iron hammer to smash plane earth, recycle threaded screw by the integrating device Corner Strapped of three-way vibration sensor on the ground.Why screw designs is become to threaded, its benefit is not only fixation of sensor integrating device on the ground, the more important thing is and can utilize the nut of screw head to carry out meticulous leveling to integrating device, has greatly reduced the not experimental error of leveling.Generally speaking, the integrating device of this earth space oscillations sensor easily carry, easy for installation and reusable.
Apparatus of the present invention are not only suitable for the vibration of test the earth three dimensions, and applicable to the various kinds of sensors of domestic frequent use.In addition, replace AB glue, adopt bolt fixation of sensor, not only convenient disassembly, and the tradition dismounting mode of avoiding knocking sensor, protected expensive sensor to greatest extent, extended the serviceable life of sensor.Another innovation is also embodied on the gib screw of integrating device, and threaded screw can be realized its meticulous leveling like a cork, has greatly reduced the alignment error of integrating device, has also improved the speed of accurate location.
Accompanying drawing explanation:
Fig. 1 is the structural representation after sensor of having installed of the present invention.
Fig. 2 is the k-k sectional view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, structure of the present invention is described in further detail.
Can be seen the structure of the integrating device of the earth space oscillations collector of the present invention by Fig. 1 and Fig. 2.
Integrating device is by base plate 100 and be connected in angle steel riser 200 and form.On orthogonal two facades (210 and 220) of riser, be provided with the screw for fixing respectively first sensor 310 and the second sensor 320; On base plate 100, be subject to two facades (210 and 220) to surround region and be also provided with the screw of fixing the 3rd sensor 330; Four jiaos of base plate 100 are provided with nail hole (101,102,103 and 104).
The sensor model number that the screw spacing of fixing each sensor can adopt according to reality is determined, due to domestic use DH610 and 891 type vibration transducers, so this device screw to the reserved corresponding spacing of this two classes sensor simultaneously.Four brad bore dia 15mm of base plate, be mainly used in inserting the long screw 400 of 25cm, it is fixed on the ground, threaded screw also can be made in these nail holes, its effect is not limited only to fixation of sensor integrating device on the ground, the more important thing is and can utilize the nut of screw head to carry out meticulous leveling to integrating device, greatly reduced the not experimental error of leveling.
In reality is implemented.This device also can comprise the optional accessory such as level tube and compass of both direction, is mainly used in the location of device.By paracentral position, be welded a steel angle structure in the steel plate lower left corner, angle steel thickness is 10mm, and height is 75mm, and wide is 108mm.On angle steel and base plate, design respectively 2 groups of bolts hole, corresponding DH610 and 891 type vibration transducers respectively, a wherein side of the bolt hole place ground proximity on base plate, 5mm is set dark, diameter is greater than the inner groovy of primary nut diameter, avoid the primary nut of sensor installation in the process of fixed set apparatus for converting to touch ground, thereby have influence on the fixed mass of sensor.
