Abstract
The utility model relates to an electromagnetic instrument assembly for penta-component earth on ocean floors, which belongs to the field of physical ocean detecting devices. The utility model takes the structures that a floating ball and a cross trapezoidal table cement counterweight are matched with an instrument base seat which has a trapezoidal groove and is in the shape like the Chinese character 'jing'; a plurality of water passing holes are arranged on an instrument box body, etc. The special technical problems in ocean detection, comprising seal, pressure bearing, corrosion prevention, flattening, shock prevention and specific requirements to the total operating performance of the instrument under ocean conditions, are solved; for example, the problems that the seawater resistance and thrust is required to be reduced as much as possible; the utility model has balanced posture in the process of subsidence and is capable of working under static state in ocean floors, etc.
Description
The utility model belongs to marine physics detecting devices field, relates to a kind of five component marine magnetotelluric instrument assemblies.
Hydrospace detection is except solving the special technique problem with respect to land survey---the low-power consumption miniaturization of for example sealing, pressure-bearing, anticorrosion, leveling, shockproof and circuit, the high-precise synchronization and seabed intelligent data acquisition of clock, overall operation performance to instrument under ocean condition also has specific (special) requirements, for example must reduce seawater resistance and thrust as much as possible, posture balancing in the sinking process, and can be at trouble free service under the static state or the like in the seabed.
At above-mentioned job requirement, the purpose of this utility model provides each parts of assembling and can work safely and reliably, and provide and to guarantee that instrument is steadily safe and reliable from the whole process of entry sinking-underwater operation-water outlet, rationally total assembling structure---five component marine magnetotelluric instrument assemblies that instrument can effectively be worked.
Above-mentioned purpose is realized by following scheme.
A kind of five component marine magnetotelluric instrument assemblies, include ball float 2, acoustics releaser 17, also include seabed electromagnetic measurement instrument pressure-bearing cabin 6, electric-field sensor is upheld gage beam 7 under water, as hanging heavy bucking ladder clump 10 and instrument box 5 and the base 8 that above-mentioned parts are installed, the wall of described casing 5 and top are to connect the framework that forms by stainless steel, described base 8 is groined type frameworks that a core has trapezoidal groove, 5 ball floats 2 are contained in the top of casing 5, bale handle 1 above it links with the corrosion-resistant steel framework of casing 5, acoustics releaser 17 is installed vertically upward and is stretched out on the casing top, one seabed electromagnetic measurement instrument pressure-bearing cabin, 6 horizontal positioned, other has along X, Y, the magnetic field sensor pressure-bearing cabin, totally 3 seabeds 19 that Z three coordinate directions are installed respectively, a magnetic field sensor is housed in each pressure-bearing cabin, a weather proof receptacle is housed on the outer end cap, the bottom is equipped with 4 along horizontal X in casing 5, the Y direction is parallel, and stagger its head of stretching out is equipped with the gage beam of extension under water 7 of electric-field sensor, below base, hang heavy integral body when sinking and be criss-cross as instrument, core is the bucking ladder clump 10 of trapezoid boss, by anchor chain 11, but the positive and negative nut body 14 of roll adjustment and the hook 15 that can throw off link to each other with instrument box, the trapezoidal groove inclined-plane of its trapezoid boss inclined-plane and groined type base 8 is complementary, be equipped with the elastic caoutchouc cushion rubber 9 that surrounds whole circle between the plane between this two inclined-plane and around base 8 and the trapezoidal clump 10, and the following wooden cushion block 12 of detouchable during water, on each sidewall of casing 5, be shaped at least 2 water holes 13.
The stainless steel frame of casing 5 is outer to post zine plate as sacrificial anode for polypropylene board 4 internal layer stainless steel frames easily lose the position.
Ball float 2 outsides are provided with frame-type metal coating hoop 3.
The weather proof receptacle in survey meter pressure-bearing cabin 6 and 3 pressure-bearing cabins 19 is provided with frame-type plastics protection outer cover 18 and 20.
Accompanying drawing 1 is a front elevation of the present utility model.
Accompanying drawing 2 is left side views of the present utility model.
Accompanying drawing 3 is plan view of the present utility model.
Accompanying drawing 4 is the utility model understructure scheme drawings.
Accompanying drawing 5 is the utility model clump structural representations.
Accompanying drawings embodiment:
As Fig. 1; shown in Figure 2; the wall and the top of casing 5 are made of stainless steel frame; its skin is surrounded by the polypropylene plastics flitch; not only anticorrosion effect is good; and because of its proportion less than water; can not increase the buoyancy burden of system; 5 ball float 2 outsides adorning at casing 5 tops all are surrounded by frame-type metal coating hoop 3 to prevent that ball float from shattering; weather proof receptacle 6 external parts also are equipped with protective case 18 in the pressure-bearing cabin; acoustics releaser 17 is installed vertically upward and is stretched out on the casing top; one seabed electromagnetic measurement instrument pressure-bearing cabin, 6 horizontal positioned; other has along X; Y; the magnetic field sensor pressure-bearing cabin, totally 3 seabeds 19 that Z three coordinate directions are installed respectively; a magnetic field sensor is housed in each pressure-bearing cabin; a weather proof receptacle is housed on the outer end cap; be equiped with 4 electric-field sensors in casing 5 bottoms and uphold gage beam under water, opening the floor area that to save on land behind the water down.The bottom 8 of casing is made the groined type framework and is cooperated the cruciform construction of clump as shown in Figure 3, Figure 4, after entry, can form 4 holes, and produce 4 water columns, make instrument sinking process very steady, the not only a whole set of instrument of structure that adds bucking ladder not reason current promotes and produces rotation to keep stable static measurement mode of operation, and need float to break off relations also to be easy to break away from it when getting rid of clump at the instrument that fulfils assignment and do not have stuck phenomenon.Between trapezoidal inclined-plane that base 5 contacts with clump 10 and flat surface, be equipped with elastic caoutchouc cushion rubber 9, before water down for preventing the cushion rubber supercompression, the wooden unit 12 that can remove when the centre is lined with down water.
The water hole 13 of casing 5 sidewalls can reduce the thrust of seawater to instrument.
Owing to adopt such scheme, the utility model not only has pressure-bearing and sealing, anti-corrosion performance Well, intensity and rigidity are reliable, non-magnetic characteristics, and have compact conformation, each one The part work coordination, entry sinking and exiting water process are steady, can not promote to produce because of current under water Rotation thereby under static state, can work safely and effectively and load and unload very easily advantage. Be suitable for Detect and prospecting etc. is divided on the continental shelf in the investigation of oil exploration, mineral deposit, seabottom geology structure.
