Fig. 1 is full ship overall construction drawing;
Fig. 2 is a small portable formula Very Shallow Water type air gun ship detail of construction;
Fig. 3 is a small portable formula Very Shallow Water type air gun ship lifting scheme drawing;
Fig. 4 is small portable formula Very Shallow Water type air gun ship rib structure figure.
The specific embodiment:
As shown in Figure 1, wherein: 1 is that air gun suspension support arm, 2 is that steel rope, 3 is that suspension centre, 4 is that ship point bow, 5 is that hull, 7 is that waterjet propulsor, 10 is that marine engine, 16 is that navigation controller, 17 is the High Pressure Air Compressor group for manually leading chain, 14, and hull 5 parts mainly are made up of the waterjet propulsor 7 that is suitable for the shallow draft ship propelling, marine engine 14, the controller 16 that navigates by water.6 designs of flat hull bottom, waterjet propulsor 7 advance, 0.75 meter ultra-shallow draft, satisfy special marine site construction requirement.The stem waterline adopts the sharp bow of lengthening to divide water type structure 4 down, has improved the line navigation precision of boats and ships, has improved energy source boat and has excited quality.
As shown in Figure 2, wherein: 1 is that air gun suspension support arm, 2 is that steel rope, 5 is that hull, 6 is that flat hull bottom, 7 is that waterjet propulsor, 8 is that air gun array gun rack, 9 is that air gun source, 10 is for manually leading chain; The steel rope 2 of manually leading on the chain 10 is connected with air gun array gun rack 8, air gun array gun rack 8 is connected with air gun source 9, air gun source 9 arrays adopt the independent hang of side machine type, manually air gun suspension support arm 1 launches, folds, and manually leads chain 10 folding and unfoldings, simple in structure, reliable operation, in light weight.Air gun array gun rack 8 adopts triangular structure.
As shown in Figure 3, wherein: 1 is that air gun suspension support arm, 2 is that steel rope, 3 is that suspension centre, 4 is that ship point bow, 5 is that hull, 6 is that flat hull bottom, 7 is that waterjet propulsor, 8 is that air gun array gun rack, 9 is air gun source; Four of hull design are used for the heavier-duty suspension centre 3 of energy source boat integral hoisting, can be implemented in that harbour lifts on the transport trolley, remote road transport.The ship trajectory control accuracy of air gun source ship is one of major quality controlling parameter of exciting of artificial seismic source, directly influences the quality of geologic information.This ship has adopted flat bottom structure, waterjet propulsion, causes the line navigation stability of boats and ships relatively poor.For this reason, as shown in Figure 3, we have adopted lengthening, cutwater bow type structure ship point bow 4, and its effect is equivalent to install a fixing rudder additional at stem.The cutwater bow actv. of lengthening has strengthened its active area, thereby the line navigation stability of this ship is effectively improved, and has improved the ship trajectory control accuracy.
As shown in Figure 4, wherein: 11 is that longitudinal rib, 12 is cross rib, and the longitudinal rib 11 of flat hull bottom 6 and side plate and cross rib 12 spacings are 40 centimetres, and the centre adds a weak rib riser, shell possesses enough shock resistances, has alleviated ship simultaneously to greatest extent and has weighed, reduces draft.
The pneumatic gun seismic source array design designs according to the air gun array modeling theory, and the focus configuration will be satisfied the exciting characteristic requirement in this zone construction.Air gun source equipment requires to take the side machine type hang, realizes that shoal water zone to the bank is at utmost near exciting.
Air gun array gun rack 8 adopts unique triangular structure to hang, and is simple in structure, firm reliable.Near-field wavelet sensor and air gun working depth sensor are fixed on the purpose made support, realize the collection of auxiliary data.
After small portable formula Very Shallow Water type air gun ship 5 finished the normal inspection of example, the deck officer was sailed out of the mooring point in driving compartment operation navigation control system, slowly by the Very Shallow Water district, enters the deep water work area.Before arriving construction big gun line, start 17 preheatings of High Pressure Air Compressor group by the machine worker.Four air gun array gun racks 8 of port and starboard alternately outwards are deployed into hull become the upright position, and locking.Improve Air compressor 17 rotating speeds and be pressurized to 2000psi, and air feed fills into 500psi for every air gun 9 to the distribution manifold.Transfer the sinking degree of depth of air gun 9 with pulling the moving chain 10 of leading to regulation.Excite air gun 9 working properly with air gun controller.Chaufeur is according to the navigation survey line, and operation navigation control system makes boats and ships reach the standard grade by setting the course line navigation.Because lengthening property bifurcation structure 4, guaranteed that this ship realizes keeping line navigation easily.Adopt side to hang structure, be beneficial to from deep water to shallow water near work, air gun 9 is not damaged.After construction finishes, this ship 5 is placed on the automobile with crane at harbour, long-distance transport is constructed to next similar work area.
