The universal dual detector is provided with an external housing. The inside of the external housing is provided with a main rotary hull. The main rotary hull is provided with a detector core. One side of the external housing is provided with an outgoing cable and a sealing bulkhead, and the other side is provided with a hydrophone probe. The main rotary hull is provided with a small rotary hull. The detector core is arranged on the small rotary hull. The small rotary hull is in an eccentric structure. The rotation axis of the small rotary hull is perpendicular to the axis of the dual detector. The universal dual detector can be widely applied to the detector field.
Description
Technical field
The utility model relates to a kind of dual sensor, particularly relates to a kind of universal dual sensor.
Background technology
We know, dual sensor is mainly used in shallow sea, shoal and deep sea petroleum exploration, mainly are comprised of with wave detector and nautical receiving set probe the land.The land is rigidly fixed on the main rotation hull with the wave detector movement of wave detector, main rotation hull is eccentric structure, be respectively equipped with bearing and bearing seat in its both sides, the bearing seat cylindrical is provided with outer protecting shell, inside, outer protecting shell two ends is respectively equipped with front skeleton and back skeleton, the outer protecting shell front end is provided with front seal plug and extraction cable, and the rear end is provided with the nautical receiving set probe.During construction dual sensor is placed horizontally at seabed or lakebed, because main rotation hull is eccentric structure, so main rotation hull can rely on eccentric weight to realize 360 ° of rotations around the axis direction of dual sensor, the land of bringing in the time of so just can the eliminating random placement dual sensor deviation of wave detector movement operative orientation, automatically the land in the dual sensor is proofreaied and correct as consistent with gravity direction with the operative orientation of the wave detector movement of wave detector, guarantee that the land can work with the wave detector movement.
Because the main rotation hull of existing dual sensor can only be around the axis direction rotation of dual sensor, can only guarantee the land with the wave detector movement all the time perpendicular to the outer protecting shell of dual sensor, therefore when the outer protecting shell of dual sensor is placed horizontally at seabed or lakebed, the land can automatic calibration be consistent with gravity direction with the wave detector movement, the land can work with the wave detector movement, but when when construction, running into seabed or lakebed surface for slope rather than level, the outer protecting shell of dual sensor just can not guarantee horizontal positioned, thereby the land will occur and the inconsistent phenomenon of gravity direction with the wave detector movement, the land just can not work with the wave detector movement, can not be effective, receive reliably vibration signal.
Summary of the invention
The utility model can only be around the axis direction rotation of dual sensor for the main rotation hull of existing dual sensor, thereby the land will occur causing the land can not receive effectively, reliably the technical matters of vibration signal with the wave detector movement with the uneven phenomenon of gravity direction with the wave detector movement when when construction runs into seabed or lakebed surface for slope rather than level, provides a kind of wave detector movement can be parallel to all the time the universal dual sensor that gravity direction, wave detector movement can receive vibration signal effectively, reliably.
For this reason, the utility model is provided with shell body, be provided with main rotation hull in the shell body, main rotation hull is provided with detector core body, is provided with extraction cable and seal plug in a side of shell body, and opposite side is provided with the nautical receiving set probe, main rotation hull is provided with little rotation hull, detector core body is positioned on the little rotation hull, and little rotation hull is eccentric structure, and the rotation of little rotation hull is perpendicular to the axis of described universal dual sensor.
The preferred technical scheme of the utility model is that little rotation hull is provided with bearing, and main rotation hull is provided with dead eye, and bearing is arranged in dead eye.
Because main rotation hull is provided with little rotation hull, little rotation hull also is eccentric structure, the wave detector movement is fixed on the little rotation hull, little rotation hull two ends are respectively equipped with bearing, bearing is arranged in the dead eye on the main rotation hull, the rotation of little rotation hull is perpendicular to the axis of dual sensor, wave detector movement and little rotation hull can be around 360 ° of rotations of rotation of little rotation hull, the wave detector movement again can be along with the axis of dual sensor is realized 360 ° of rotations simultaneously, so when construction, dual sensor is positioned over seabed or lakebed, no matter whether seabed or lakebed are horizontal surface, main rotation hull and little rotation hull can be realized 360 ° of rotations around the axis of oneself, automatically the operative orientation of the wave detector movement in the dual sensor is proofreaied and correct as consistent with gravity direction, guarantee that the land can work with the wave detector movement, and effectively, receive reliably vibration signal.

1. extraction cable; 2. front seal plug; 3. front skeleton; 4. bearing; 5. the master rotates hull; 6. wave detector movement; 7. outer protecting shell; 8. bearing; 9. back skeleton; 10. nautical receiving set is popped one's head in; 11. bearing; 12. little rotation hull; 13. land wave detector.
Embodiment
Embodiment 1:
Dual sensor as depicted in figs. 1 and 2, it comprises land wave detector 13 and nautical receiving set probe 10.The land is provided with main rotation hull 5 with wave detector 13, main rotation hull 5 is eccentric structure, is respectively equipped with bearing 4 and bearing 8 in its both sides, and bearing 4 and bearing 8 are erected at respectively on the bearing seat, the bearing seat cylindrical is provided with outer protecting shell 7, and inside, outer protecting shell 7 two ends is respectively equipped with front skeleton 3 and back skeleton 9.In addition, seal plug 2 and extraction cable 1 before outer protecting shell 7 front ends are provided with, the rear end is provided with nautical receiving set probe 10.
Also be provided with little rotation hull 12 on main rotation hull 5, little rotation hull 12 also is eccentric structure.The land is fixed on the little rotation hull 12 with the wave detector movement 6 of wave detector 13, and the two ends of little rotation hull 12 are respectively equipped with bearing 11, also is provided with dead eye on the main rotation hull 5, and bearing 11 is arranged in the dead eye on the main rotation hull 5.The rotation of little rotation hull 12 is perpendicular to the axis of dual sensor, 360 ° of rotations can be done with the wave detector movement 6 of wave detector 13 around the rotation of little rotation hull 12 with little rotation hull 12 in the land, and the land again can be along with the axis of dual sensor is realized 360 ° of rotations with wave detector movement 6 simultaneously.
When construction, dual sensor is positioned over seabed or lakebed, no matter whether seabed or lakebed are horizontal surface, main rotation hull 5 and little rotation hull 12 can be realized 360 ° of rotations around the axis of oneself, automatically the land in the dual sensor is proofreaied and correct as consistent with gravity direction with the operative orientation of wave detector movement 6, guarantee that the land can work with the wave detector movement 6 of wave detector 13, can receive vibration signal effectively, reliably.
The utility model is converted to electric signal with nautical receiving set probe 10 physical signallings that receive, and electrical signal transfer is gone out, and finishes its course of work.
Embodiment 2:
Dual sensor as shown in Figure 3 and Figure 4, the difference of itself and dual sensor illustrated in figures 1 and 2 is that main rotation hull 5 is provided with two little rotation hulls 12, the land is rigidly fixed in respectively on two little rotation hulls 12 with the wave detector movement 6 of wave detector 13, can realize being used in combination of two wave detector movements 6, satisfy the further needs of submarine oil exploration.
