Abstract
The utility model relates to a shallow water and river exploration air gun array retracting device applied to retracting geophysical exploration air gun arrays in shallow water and rivers not deeper than 3 meters. Three cylindrical inflatable rubber float bowls are arranged in parallel and are connected to form a floating platform; an air gun support is fixed between every two float bowls; a manual guide chain is suspended on beams of the two air gun supports; and the lower part of the manual guide chain can be used for suspending a fixed-depth rope, and the lower end of the fixed-depth rope is used for suspending an air gun. The shallow water and river exploration air gun array retracting device has the advantage of realization of safe, high-efficiency and environmental-protection construction operations in shallow water areas, strong capacity of preventing foreign matter in the water from winding, and no occupation on the space of an energy source boat. The air gun is manually sunk and lifted, and can be just put under the water surface from a gap between every two float bowls.
Description
Technical field
The utility model relates to the geophysical exploration technology field, specifically is that a kind of depth of water that is used for is carried out geophysical survey air-gun array draw off gear less than 3 meters Very Shallow Water and river.
Background technology
When carrying out geophysical survey across the sea, use be artificial air gun source.The draw off gear of existing artificial pneumatic gun seismic source array has two kinds: side machine type pneumatic gun seismic source array draw off gear and pull-type air gun source battle array draw off gear.These two kinds of draw off gears are mainly used in the waters of the depth of water more than 3 meters to carry out in the geophysical survey collection operation.Yet,, also do not have to be fit to the air gun source draw off gear of this feature on water at the narrow river water area of shallow water area or navigation channel of the depth of water less than 3 meters.Up to the present can only adopt explosive as man-made explosion.
At present, employed side machine type and after drag the energy source boat of formula air-gun array draw off gear all can not be used for this type of shallow water area operation, its reason has:
What drag the employing of formula air gun extension and retraction system 1. is special-purpose buoyancy aid hangs pull-up rifle array in water device.This structure makes gun depth be necessary for 4 meters at least, simultaneously owing to longer as the boats and ships of carrying platform, reaches more than 60 meters at construction state scope of operation straight line, can not adapt to crooked river construction.Therefore, be lower than 3 meters narrow water in the depth of water, this device can not adopt.
What 2. side machine type air gun extension and retraction system adopted is to build supporting cantilever on hull, hangs the air-gun array that draws in the water.To the restriction of the violent impact shock of hull, the spreading width of construction operation air gun is more than 18 meters when sending out in gunslinging owing to be bullied, and so just makes that mobility is not enough when the construction of narrow waterway, can not construct in this waters.
3. above-mentioned two kinds of devices are in the river or Very Shallow Water when construction, because the water surface or foreign material under water, damage parts in the water of air gun system to the lash of air-gun array, make system's cisco unity malfunction.
The utility model content
The purpose of this utility model is: a kind of Very Shallow Water and river exploration air-gun array draw off gear is provided, can construct less than 3 meters Very Shallow Water, river, lake waters in the depth of water, accomplish that simultaneously whole apparatus structure is simple, can adopt the TEU (Twenty-foot Equivalent Unit) transportation, solve safe, efficient, the environmental protection construction problem of air gun source in this waters.
The technical solution adopted in the utility model is: Very Shallow Water and river exploration air-gun array draw off gear, mainly by floating drum, platform, air gun support, manually lead chain, the depthkeeping rope is formed, it is characterized in that: three cylindrical inflatable rubber floating drums are arranged in parallel, 300~600 mm distance are arranged between two floating drums, be fixed with steel plate on three floating drums, three floating drums are connected and form a raft.Be fixed with the herringbone frame between two floating drums, the welded top of herringbone frame has a beam.Herringbone frame and beam are formed the air gun support.The beam of air gun support is relative with the gap between two floating drums.On the beam of two air gun supports, be hung with and manually lead chain.Manually lead the chain bottom and can hang the depthkeeping rope, air gun is hung in depthkeeping rope lower end, realizes manual sinking and promotes air gun.Air gun can just be transferred to below the water surface from the gap between two floating drums.The raft of three parallel floating drum compositions has two air gun supports that are parallel to each other, and can set up two subarrays.The plane can lay big gun cable and for personnel's usefulness of walking on the platform.
Described steel plate is a demountable structure, is promptly connected by screw between the steel plate.
Described manually lead chain in the distance of hitch point on the beam between 2.5~3.5 meters.
The beneficial effects of the utility model: the utility model Very Shallow Water and river exploration air-gun array draw off gear, the construction space size is little, adapts to the narrow water construction.Solved the air-gun array man-made explosion construction difficult problem of Very Shallow Water, river, lake waters, realized safe, efficient, environmental protection construction operation in these waters.Foreign matter winding ability is strong in the anti-water, does not take the space of energy source boat, can select extremely light-draft spitkit.
