Description
Technical field
The invention belongs to submarine earthquakes to monitor field, be launched more particularly to one kind based on rigidly connected submarine seismograph
Support device, suitable for submarine seismograph shallow sea area use when and seabed coupling.
Background technique
Submarine seismograph is the ground designed for the micro-vibration caused by submarine observation earthquake and other earth crust structure events
Shake instrument, be new and high technology developed in recent years, hydrocarbon exploration, scientific research, in terms of have extensive use
On the way.
Currently, laying with way of recycling for submarine seismograph is that submarine seismograph is affixed directly on device, from sea
It launches in seawater, whole device sinks down into seabed by self gravity；When recycling, release command is sent by water surface deck unit
To the receiver being fixed on submarine seismograph, receiver starts relieving mechanism after receiving release command, make submarine seismograph with
Device separation, submarine seismograph emerge by natural buoyancy.But such structure uses free putting mode, seabed
Shake moment for contacting with seabed of instrument, be easy to cause strenuous vibration, and such constitutional balance and stability are poor, neritic area not
Flat seabed is easy rollover, and the impact vulnerable to ocean bottom currents is covered by silt.Simultaneously as the structure of its open type,
It also tends to phenomena such as being walked by the fishing of fishing boat otter-trawl, dragging shifts occur, leads to that the coupling in submarine seismograph and seabed is insufficient to be
To loss.In addition, if the intrinsic frequency of apparatus structure in submarine seismograph working band, then will affect submarine seismograph number
According to collection and reduce the accuracy of DATA REASONING.

The interference of drift net.
Further, the mode that is connected by screw bolts between the lateral bolster strut and side cover, side cover with a thickness of
5mm。
Further, the wire device for fusing is mounted on above submarine seismograph, as submarine seismograph and chassis
Bridge is connected, the wire device for fusing being fixed on submarine seismograph is sent a signal to by water surface deck unit, wire is molten
Disconnected device receives fuse metal silk after signal, and the linkage on wire device for fusing glides, and rope is sliding from linkage
De-, submarine seismograph is separated with device, completes reclaimer operation.
The present invention compared with prior art the utility model has the advantages that
1, the prior art needs that the device for carrying instrument is integrally laid and recycled in practical applications；The device can be realized
Independent release to submarine seismograph can greatly reduce the difficulty of equipment recycling, promote operating efficiency.
2, the prior art does not have shield or shield and device to be flexibly connected, and interference external to seabed trawlnet etc. is resisted
Ability is poor；The present invention makes entirely to launch support device and protection by the way that the structure for launching support device is designed and is optimized
Cover is connected as one with rigid manner, and main body rack and side cover bottom can sufficiently be coupled with seabed, is prevented under overall structure
It falls into, the shaped hollow round table structure of side cover can resist the impact of ocean current and the dragging of fishing boat trawlnet well.
3, it is tested through Modal Analysis, show that structure of the invention intrinsic frequency is greater than 237.09Hz, effectively avoid seabed
Seismographic working band realizes effective anti-while ensureing that submarine seismograph is normally collected with accurate measurement data
It drags, protecting against shock.

Specific embodiment
Below by embodiment combination attached drawing, to be further explained to technical solution of the present invention, but guarantor of the invention
Shield range is not limited in any form by embodiment.
Embodiment 1
As shown in Figures 1 to 5, a kind of to launch support device based on rigidly connected submarine seismograph, it includes side cover
1, main body rack 2, lateral bolster strut 3, chassis 4, anti-sticking vertical tube 5, wire 7, wire device for fusing 8, rope 9；
The main body rack is the structure made of a plurality of rigid strip structure cross weld about point symmetry；
Chassis is located at main body rack lower center position, and chassis and main body rack are connected with welding manner, can guarantee with
The abundant coupling in seabed；The chassis of main body rack lower center position and anti-sticking vertical tube are welded as an open-frame and rigidly tie
Various otter-trawls, diver net are stood for 650mm with a thickness of 10mm, chassis diameter convenient for debugging to equipment in structure, chassis
Interference.
Lateral bolster strut and the end that strip structure is fixed on welding manner, lateral bolster strut and strip structure are in 60 °
Angle, opposite side mask play a supportive role；
Anti-sticking riser upper end is fixedly connected with main body rack upper, annular structure vertical, and lower end is vertical and solid with welding manner
Due to main body rack bottom annular structure, anti-sticking vertical tube setting plays position-limiting action to submarine seismograph in submarine seismograph surrounding；
Side cover is hollow round table structure, side cover with a thickness of 5mm, and without upper top surface and bottom surface, side cover with
Lateral bolster strut is bolted, and side cover is equipped with permeable hole, passes through convenient for water flow, reduces water flow impact pressure.

9 one end of rope is connected on chassis 4, and the other end is tied to form a retaining ring and covers on the linkage of wire device for fusing 8, metal
There are two rotatable linkages for silk device for fusing 8, are located at left and right sides of submarine seismograph top, two rotatable
Linkage is connected by wire 7, and in use state, rope 9, wire 7 are in tensioned state, thus submarine earthquake
Instrument 6 is tightly attached on chassis 4.
The process for laying and recycling of the invention device is as follows:
When laying, main body rack 2 is hooked by deck hanging device and slings the device with anti-sticking 5 infall of vertical tube, transferred
Side covers 1 low wide and up narrow hollow round table shape structure and plays buffer function in the process, avoid because lowering velocity it is too fast caused by it is acute
Violent shock is swung；When work, main body rack 2 and side are covered 1 bottom and can sufficiently be coupled with seabed, prevent overall structure from sinking, side
The hollow round table shape structure of cover 1 can resist the impact of ocean current and the dragging of fishing boat trawlnet, overall structure intrinsic frequency well
Effectively avoid the working band of general submarine seismograph；When recycling, wire device for fusing is issued instructions to by deck unit
8, wire device for fusing 8 fuses the wire 7 on the hinge for being connected and fixed rope 9, and hinge rotates at this time, for fixed sea
The rope 9 of bottom seismic detector 6 unclamps, and submarine seismograph 6, to sea is floated up to, is worked under the buoyancy of itself by water surface ship's deck
Personnel salvage submarine seismograph 6, are then recycled to deck.
As shown in fig. 6, the dispensing support device first natural frequency is 237.09Hz, submarine seismograph is effectively avoided
Working band, can guarantee the normal data collection of submarine seismograph and measurement work.
