Test, it is necessary to combined type sea bottom earthquake-capturing number of nodes more to hundreds of, for the pendulum of combined type sea bottom earthquake-capturing node
Put and bring great difficulty with constructing operation, therefore we devise the design that upper lower flange is maintained plane, internally increase
The structure of special support, is uniformly distributed five titanium alloy columns, by finite element analysis software between upper lower flange
(ANSYS softwares) carries out mechanical analysis, determines that section structure, internal capacity optimal size ratio and optimization encapsulation scheme set
Meter, the compressive resistance for making it to bear the 1500m depth of waters, such structure neither influences the uniform layout of internal integral battery door group,
Again can be on the premise of nacelle weight be reduced, it is ensured that its 1500 meters compressive resistance, reduce offshore construction difficulty.
Further, combined type sea bottom earthquake-capturing node (GOBS) delivers way of recycling using heaving pile.With single cabin ball
OBS is different, and according to the difference of seabed test zone, every side line of selection delivers the number of combined type sea bottom earthquake-capturing node

Buckle.Every combined type sea bottom earthquake-capturing node both sides equidistantly hang 2KG counterweights, are used to reduce hawser gushing in seabed
The influence brought to data record is moved, because combined type sea bottom earthquake-capturing node is reclaimed is reclaimed around cable by winch, compared with
The risk of missing of combined type sea bottom earthquake-capturing node is greatly reduced from floatable submarine seismograph.
Further, the design of the arc expansion bar of the upper lower flange in combined type sea bottom earthquake-capturing node, upper method
Blue arc strip external diameter is more smaller than the arc strip internal diameter of lower flange, and such combined type sea bottom earthquake-capturing node can when putting
To block up and down, fall together up and down, will not slip out, the placing space that can not only save on ship, and extract data and
Combined type sea bottom earthquake-capturing node on clock to reducing operation difficulty.The top surface of every arc strip also has two screwed holes, makees
It is extending bore, every combined type sea bottom earthquake-capturing node can be external by these extending bores according to the purpose and demand of experiment
Equipment, such as external buoyant material repacks the seabed acquisition node from floatable into.
By test of many times and actual verification, the diffuser of GOBS clamps the special of poly (methyl methacrylate) plate using double-layer seal rings
Structure.Because of generally one titanium alloy metal cabin of sealing of GOBS, it is contemplated that sealing problem, need externally to retain an instruction again
The show hole of lamp understands the working condition of combined type sea bottom earthquake-capturing node, and good sealing can be both realized using diffuser
Effect, turn avoid the inadequate shortcoming of the pressure-resistant depth of lucite, and the design of this translucent construction part is outside the metal at deep-sea
Still belong in the earthquake-capturing node of shell combined type sea bottom the first.
Because GOBS combined type seas bottom earthquake-capturing intra-node space is limited, so using compact conformation, compact
Full-shape wave detector as transducer, natural frequency is 15HZ, and open loop damping is 0.6, and Coil resistance is 1564 ohm, sensitivity
It is 74.8V/m/s, it is 13.2g to hang weight.Lifted by introducing electrical feedback working sensor frequency band for 10HZ~
300HZ.Because full-shape wave detector does not need adjustment angle.A large amount of inner spaces can be saved, overall dimensions are compact, meet GOBS
Combined type sea bottom earthquake-capturing joint behavior index request.Additionally, the combined type sea bottom earthquake-capturing node is using overall electricity
Pond covers one assembly model, and reason is that combined type sea bottom earthquake-capturing node is mainly used in high density sea floor exploration, every time sea
Quantity required for examination is expected at hundreds of, so the workload for producing and debug is very big, combined type sea bottom earthquake-capturing
