Present bay cable exploration, most dual sensors that adopt carry out underwater seismic survey.Existing dual sensor adopts the unitized construction of nautical receiving set and moving-coil wave detector, adds just can be bundled on the subsea cable behind the shell to use, with the coupling of assurance and cable and seawater.
And existing dual sensor shell adopts cylindrical structure, but because in the process of high tide ebb, seawater is very large to the impulsive force of wave detector, and the noise of generation is also very large, severe jamming seismic wave effectively, reduced the signal to noise ratio (S/N ratio) of seismic data.
Because the limitation that above-mentioned existing dual sensor shell exists, the design people is based on being engaged in for many years abundant practical experience and professional knowledge of this type of product design manufacturing, and the utilization of cooperation scientific principle, positive research and innovation in addition, in the hope of founding a kind of impulsive force that can reduce seawater, increase the coupling area with the seabed, be conducive to improve the dual sensor shell of the signal to noise ratio (S/N ratio) of seismic data.
Summary of the invention
The purpose of this invention is to provide a kind of impulsive force that can reduce seawater, increase the coupling area with the seabed, be conducive to improve the dual sensor shell of the signal to noise ratio (S/N ratio) of seismic data.
For achieving the above object, the invention provides a kind of dual sensor shell, comprise: two and half housings that matched by shape engage the housing that forms, the accommodating cavity of the concrete hollow of described housing, the outside surface of described housing is flat fusiformis, at least one sidepiece at described housing offers the nautical receiving set window that is connected with described accommodating cavity, bundlees grooves along being circumferentially with some on the outer wall of described housing.
Aforesaid dual sensor shell, wherein, the xsect ovalize of described housing.
Aforesaid dual sensor shell, wherein, the peripheral correspondence of described two and half housings offers a plurality of screws, and described two and half housings are connected by the screw and nut through described screw.
Aforesaid dual sensor shell, wherein, the length of described housing is 359.79mm, the width at its middle part is 86.60mm.
Aforesaid dual sensor shell, wherein, the width of described binding groove is 14mm.
Aforesaid dual sensor shell, wherein, the length of described nautical receiving set window is 34.24mm.
Compared with prior art, the present invention has following characteristics and advantage:
Because the housing of dual sensor shell of the present invention adopts flat fusiformis, the xsect ovalize of housing, increased the coupling area in itself and seabed, reduced the impulsive force of seawater, improved the signal to noise ratio (S/N ratio) of seismic data, thereby greatly improved the quality of seismic data, pushed the application of dual sensor to certain height.

Embodiment
With the description of the specific embodiment of the invention, can more be well understood to details of the present invention by reference to the accompanying drawings.But the specific embodiment of the present invention described here only is used for explaining purpose of the present invention, is limitation of the present invention and can not be understood as by any way.Under instruction of the present invention, the technician can conceive based on arbitrarily possible distortion of the present invention, and these all should be regarded as belonging to scope of the present invention.
Please refer to Fig. 1 to Fig. 3, be respectively the structural representation after dual sensor shell of the present invention makes up; Main TV structure synoptic diagram and the backsight structural representation of half housing of the present invention.As shown in the figure, the dual sensor shell that the present invention proposes, comprise: two and half housings 2 that matched by shape engage the housing 1 that forms, the accommodating cavity 3 of housing 1 concrete hollow, be used for holding nautical receiving set and moving-coil wave detector (not shown), the outside surface of housing 1 is flat fusiformis, and namely the middle part of housing 1 is tubular, and its both sides are the protruding top shape of convergent along the axis of housing 1.At least one sidepiece at housing 1 offers the nautical receiving set window 4 that is connected with accommodating cavity 3, and the position of offering the nautical receiving set in position and the accommodating cavity 3 of nautical receiving set window 4 is corresponding, so that nautical receiving set receives seismic events by nautical receiving set window 4.On the outer wall of housing 1, along being circumferentially with some binding grooves 5, being convenient to cable and tying on housing 1 by binding groove 5.Like this, because the housing 1 of dual sensor shell of the present invention adopts flat fusiformis, increased the coupling area in itself and seabed, reduced the impulsive force of seawater, improved the signal to noise ratio (S/N ratio) of seismic data, thereby greatly improved the quality of seismic data, pushed the application of dual sensor to certain height.
In the present embodiment, the xsect ovalize of housing 1, thus more be conducive to the coupling area in housing 1 and seabed, reduce the impulsive force of seawater, improve the signal to noise ratio (S/N ratio) of seismic data.
Shown in Fig. 2,3, in order to guarantee the structural strength of housing 1, the peripheral correspondence of two and half housings 2 offers 6, two half housings 2 of a plurality of screws and is connected by the screw and nut through screw 6, is integrated so that two and half housings 2 are fastenedly connected.
In the present embodiment, the length of housing 1 is 359.79mm, and the width at its middle part is 86.60mm.The width of binding groove 5 is 14mm.The length of nautical receiving set window 4 is 34.24mm.Certainly, the concrete size of housing 1 of the present invention, binding groove 5, nautical receiving set window 4 can be selected according to actual condition, and the present invention is not restricted this.
