Description
[technical field]
The present invention relates to oceanic earthquake observation technology field, relate in particular to a kind of delivery device of submarine seismograph.
[background technology]
Submarine seismograph (ocean bottom seismometer, OBS) and the Submarine seismic observation forming be the new and high technology that development in recent years is got up, at hydrocarbon exploration, scientific research, the aspect such as prevent and reduce natural disasters, having been widely used, is the developing new growing point of geophysical instrument and Detection Techniques.Submarine seismograph is a kind of seismic observation system that wave detector is directly placed on to seabed, in marine geophysical survey and research, both can be for the detection to artificial ocean seismic section, also can be for the observation to earthquake, the dynamic characteristic that it is surveyed and observed result can develop for the velocity structure of research oceanic crust and earth mantle and subduction zone, trench, trough, also can be for studying seismic tomography and seismicity and the earthquake prediction etc. of earthquake.
At present, the developed countries such as Japan and the U.S. all adopt underwater robot casting submarine seismograph, and the expense of throwing in is once more expensive; In addition, the input mode of remaining submarine seismograph is all directly to throw in and freely land to seabed from sea substantially.Adopt marine directly casting submarine seismograph, submarine seismograph in launch process with moment of contact with sea water, as easy as rolling off a logly cause unexpected high vibration, likely directly submarine seismograph is caused damage; In addition, the decline rate of submarine seismograph in deep-sea is 2 meter per seconds, directly impacts seabed under this decline rate, to accurate seismic monitoring and testing apparatus, can produce certain shock effect, and what have even can cause the damage of equipment.
In order to overcome above-mentioned shortcoming and difficulty, in the urgent need to designing a kind of economy, efficiently impact-proof structure just has very strong realistic meaning for the input of submarine seismograph.
[summary of the invention]
The invention provides a kind of simple in structurely, safe and reliable, effectively reduce and impact, protection instrument and equipment is not damaged, economic, the delivery device of submarine seismograph efficiently.
In order to realize foregoing invention object, the technical solution used in the present invention is:
The delivery device of submarine seismograph, comprises framework and heavy coupling frame, and heavy coupling frame 2 is installed on the bottom of framework; Described framework prevents sea beat and keeps seismograph in horizontality, and described heavy coupling frame provides the support body of negative buoyancy and lower hollow for one to seismograph; Described framework two ends are provided with and connect the support bar that supports heavy coupling frame; Described frame mid portion is provided with for taking up the instrument tank of Submarine seismic observation equipment, and the top of instrument tank is provided with a hanging ring of being convenient to be affiliated to; On described framework the upside of corresponding instrument tank also pivot joint one lever that prizes instrument tank is installed, lever one end is provided with instrument upper end hanging ring and hooks the half unlimited hook that cover coordinates, and the lever other end stretches out framework and is connected with endways the balancing weight that levers up instrument tank and interior Submarine seismic observation equipment thereof; Between described balancing weight and lever end, be connected with and flexibly connect rope, flexibly connect the balancing weight in the vertical direction of rope bottom connection lower than heavy coupling frame setting.
Preferably, described heavy coupling frame is horizontally disposed with respect to framework bottom surface.
Preferably, the torsional forces that described balancing weight produces on lever is greater than the torsional forces that instrument tank and interior Submarine seismic observation equipment thereof produce on lever.
Preferably, described in, flexibly connect rope and be greater than the height after framework is connected with heavy coupling frame at the height of vertical direction.
The invention has the beneficial effects as follows:
The present invention is by a leverage of design, and the two ends of leverage connect respectively instrument tank and the balancing weight that Submarine seismic observation equipment is housed.Balancing weight is connected by flexibly connecting rope with lever, instrument upper end hanging ring hooks the half unlimited hook that cover is matched with lever, during use, even under buoyant of sea water effect, the torsional forces producing on lever due to balancing weight is greater than the torsional forces that instrument tank and interior Submarine seismic observation equipment thereof produce on lever, lever triggers the instrument tank that takes up Submarine seismic observation equipment all the time, when submarine seismograph lands near seabed, balancing weight first contacts seabed, by flexibly connecting the contraction of rope, the weight of lever balancing weight is discharged, instrument tank is come off from the hook on lever top, directly through heavy coupling frame bottom, drop on lentamente in bottom silt, compare the drop of instrument tank from sea to seabed in the past, the drop of instrument tank landing is equivalent to the difference in height between instrument tank and balancing weight, greatly reduced drop, greatly weakened impulsive force when the interior Haiti of instrument tank seismological observation equipment lands, play effective buffer action, impact to earthquake exact instrument while having avoided equipment to sink at a high speed, protection instrument and equipment is not damaged.
[accompanying drawing explanation]
Fig. 1 is that stereoscopic mechanism schematic diagram is looked on the right side, front side of the present invention.
[embodiment]
The delivery device of submarine seismograph, as shown in Figure 1, comprise framework 1 and heavy coupling frame 2, heavy coupling frame 2 is installed on the bottom of framework, framework 1 prevents sea beat and keeps seismograph in horizontality, and heavy coupling frame 2 provides the support body of negative buoyancy and lower hollow for one to seismograph; At framework 1 two ends, be provided with and connect the support bar 3 that supports heavy coupling frame 2, be provided with for taking up the instrument tank 4 of Submarine seismic observation equipment at framework 1 middle part, the top of instrument tank 4 is provided with a hanging ring of being convenient to be affiliated to 40; On framework 1 upside of corresponding instrument tank also pivot joint one lever 5 that prizes instrument tank 4 is installed, lever one end is provided with instrument tank 4 top hanging rings 40 and hooks the half unlimited hook 50 that cover coordinates, and lever 5 other ends stretch out framework and are connected with endways the balancing weight 6 that levers up instrument tank 4 and interior Submarine seismic observation equipment thereof; Between balancing weight 6 and lever 5 ends, be connected with and flexibly connect rope 7, balancing weight 6 in the vertical directions that flexibly connect rope 7 bottoms connections arrange lower than heavy coupling frame 2.
