Description
Technical field
This utility model relates to the hard-wired holder device of earthquake towed cable, belongs to the damping device technical field of tow.
Background technology
Marine acoustics Detection Techniques are widely used in marine geologic survey field, and wherein marine seismic survey has reached its maturity as important Detection Techniques, are requisite marine geologic survey means.Marine seismic exploration equipment mainly includes acquisition workstation, focus, reception towing cable and other auxiliary equipments etc..The major function of seismic receiver towing cable is to receive focus to launch the acoustic signals launched through subsea strata, then underwater signal is converted to the signal of telecommunication.But, the factors such as current earthquake towed cable exists following defect: (1) is afloat actual to be measured, and earthquake towed cable is typically due to ship wake effect rear dragging in stern, propeller for vessels noise jamming in water affect signals collecting；(2) earthquake towed cable cannot adjust angle freely to change the suitable position relationship of towing cable and focus, to reach optimal observation system, thus obtains the seismic data that quality is high.
Measuring the accumulation of working experience through offshore earthquake for many years, we have invented earthquake towed cable mounting bracket device, it is convenient to bring for offshore earthquake measurement, improves the work efficiency of sea survey simultaneously.
Utility model content
The purpose of this utility model is to overcome the drawbacks described above being currently used for earthquake towed cable existence, propose a kind of for the hard-wired holder device of earthquake towed cable, by changing focus and the relative position relation receiving towing cable, so that it is determined that optimal observation system, it is convenient to bring for offshore earthquake measurement, improves the work efficiency of sea survey simultaneously.
This utility model is to use following technical scheme to realize: a kind of for the hard-wired holder device of earthquake towed cable, including support, chock and pull bar, ship side afterbody is fixed in support one end, and the other end is provided with chock；Pull bar is set to the metallic rod of two bending；Mid-stent is provided with draw-in groove matching used with pull bar bending part；Support fixing point along ship side afterbody rotates, and drives chock to move to outside boats and ships；Chock position on support is adjustable；Support, pull bar and ship side constitute three-legged structure.
Further, the angular range that support rotates around fixing point is 0-90 °.The position of the boats and ships removed as required, adjusts the angle rotated.
Further, chock is slidably connected on support.Slip chock is fixing after determining the position on support.
Further, support is provided with adds the support bar of stiff stability.By support bar, make rack body the most solid firmly.
Further, chock is provided with the towing cable freely stretched.Towing cable is positioned over inside boats and ships, moves to outside boats and ships by chock, it is simple to build optimal observation system.
The beneficial effects of the utility model are:
(1) described in the utility model for the hard-wired holder device of earthquake towed cable, can be widely applied to portable installation and the folding and unfolding of marine seismic survey towing cable, be primarily adapted for the ship side extenal fixation installation of towing cable (reception unit), folding and unfolding work in split type (transmitter unit and reception unit are separately) offshore earthquake equipment；
(2) described in the utility model for the hard-wired holder device of earthquake towed cable, there is the characteristic such as agility, safety, the most not only can ensure that the freedom retractable of towing cable, and can the suitable position relationship changing towing cable and focus freely, to reach optimal observation system, thus obtain the seismic data that quality is high.

Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, this device is a kind of secure mounting arrangements for marine seismic survey equipment earthquake towed cable, it is mainly used in fixed installation and the folding and unfolding of the towing cable such as ocean single-channel seismic, shallow seismic profile measurement.
As shown in figs 2-4, this device is broadly divided into three parts: support 1, chock 2, pull bar 3.
Support 1 is the main body of this device, uses 2 cun of stainless steel tube materials to make, length about 5m, one section of intersection point elbow being furnished with right-angle side, is used for 4 sides on the quarter and fixes, and the fulcrum rotated as support 1 fixedly mounts chock 2 on the other end.Can reequip according to the requirement of concrete operation ship.
Chock 2: the square device being made up of 4 root lengths about 30cm, rotary bearing.
Pull bar 3: using 1 cun of stainless steel tube material to make, there is the intersection point elbow of right-angle side at two ends, plays connection support 1 and acts on.
When using such as Fig. 5-Fig. 6, using 1 one sections of support as axle, it is fixed on ship side 4 so that it is be freely rotatable, other end fixed installation chock 2, make towing cable freely stretch in chock 2.Pull bar 3 and support 1, ship side 4 is utilized to form triangle, to reach stiff stability.When the intersection point of support 1 with the perpendicular arm of angle of ship side 4 is spent, chock 2 reaches maximum with the distance of ship side 4, i.e. the distance of outer of earthquake towed cable reaches maximum, also illustrates that focus reaches maximum with the vertical dimension of earthquake towed cable.Along with diminishing of angle, focus diminishes with the vertical dimension of earthquake towed cable.Utilize chock 2 that the relative position relation (observation system) of the two with the length of freedom retractable earthquake towed cable, can be changed more quickly, easily, so that it is determined that optimal observation system.
This device can improve further, utilizes the position changing chock 2 to change the distance propped up outside towing cable, thus arrives preferable observation system.
Certainly, foregoing is only preferred embodiment of the present utility model, it is impossible to be considered for limiting scope of embodiments of the present utility model.This utility model is also not limited to the example above, equalization change and the improvement etc. that those skilled in the art are made in essential scope of the present utility model, all should belong in patent covering scope of the present utility model.
