Example 1
FIG. 1 is a schematic view of a submarine sediment probe 100 according to a first embodiment of the invention; FIG. 2 is an internal structural view of FIG. 1; fig. 2 is a cross-sectional view taken along line A-A of fig. 1 (with portions of the structure hidden from view). Referring to fig. 1 (see fig. 2 and 3 in combination), a submarine sediment probe 100 in the present embodiment includes a housing 10 and a detector 30. The outer peripheral surface of the envelope 10 has a radially recessed groove C1, and the groove C1 extends in the axial direction of the envelope 10. And one end of the groove C1 in the axial direction thereof is a necking groove C11 of which the cross section is gradually reduced. The cartridge 10 has a sight glass 20, the sight glass 20 being located at the smaller cross-section end of the bottom surface P0 of the necking groove C11. The detector 30 is disposed in the envelope 10 and is opposite to the inspection window 20.
The use method of the submarine sediment probe 100 in the embodiment of the invention is to drag the submarine sediment probe 100 pressed on the submarine sediment, so that the submarine sediment probe 100 moves on the submarine sediment layer. During the movement of the subsea sediment probe 100, the detector 30 optically detects sediment from the window 20.
During the detection process, the submarine sediment probe 100 is pressed down into the submarine sediment layer under the action of its own weight, so that part of sediment below the submarine sediment probe is squeezed into the groove C1. The sediment pushed into the groove C1 is discharged in opposite directions in the axial direction when the submarine sediment probe 100 is pulled to move. The sea water in the sediment is extruded by the necking groove C11 during the discharging process, and the sediment is extruded to be tightly attached to the outer surface of the observation window 20. The seawater is extruded and tightly pressed against the sediment of the inspection window 20, so that the influence of the obstruction of the seawater or the excessive looseness of the sediment on the detection light of the detector 30 is greatly avoided, and the detection data of the detector 30 can accurately reflect the property of the sediment, so that an accurate detection result is obtained.
The groove C1 is intended to enable the sediment in the groove C1 and the tube housing 10 to be squeezed out of the seawater contained in the sediment facing the detection window 20 during the movement of the submarine sediment probe 100, and to compress the outer surface of the detection window 20 as much as possible, so as to ensure that the detector 30 can directly detect the sediment through the detection window 20 without being affected or as little as possible by the seawater. Based on this, the groove C1 in the present embodiment may be provided in various forms, for example, the tapered groove C11 of the groove C1 is connected at a larger-section end thereof with the constant-section groove C12. The necking groove C11 is defined by a groove bottom surface P0 and two pairs of groove side surfaces P1. The groove bottom surface P0 is an inclined surface, and is configured such that its depth becomes gradually smaller from one end near the constant-section groove C12 to the other end thereof. Alternatively, the spacing between the two groove sides P1 defining the necking groove C11 is gradually reduced, forming a splayed-like necking. The groove side surface P1 may be a flat surface or a smooth arc surface.
In one embodiment of the invention, the cartridge 10 includes a smoothly connected cylindrical section 12 and a hemispherical section 11, with the reduced diameter groove C11 extending into the outer surface of the hemispherical section 11. Thus, when the other end of the submarine sediment probe 100 is lifted, the hemispherical segment 11 is pressed onto the sediment layer, the groove C1 and the necking groove C11 can better fit the sediment layer, and the sediment can enter and move out of the necking groove C11, and is pressed onto the outer surface of the inspection window 20 in the necking groove C11. To make the press fit between the inspection window 20 and the deposit tighter, the hemispherical segment 11 has a counterweight 13.
In one embodiment of the present invention, a support plate 14 is provided within the cartridge 10, the support plate 14 being connected to an axially intermediate position of the cartridge 10. A first mounting plate 15 is connected between the hemispherical section 11 and the support plate 14, and a detector 30 is fixedly connected to the first mounting plate 15 and faces the detection window 20. The support plate 14 divides the interior of the cartridge 10 into a first chamber Q1 and a second chamber Q2. The detector 30 is disposed in the first chamber Q1. A power supply 40 configured to electrically connect the detector 30 and supply power to the detector 30 is disposed in the second chamber Q2. Referring to fig. 3 again, in order to avoid the submarine sediment probe 100 from being disturbed by seawater or other external force to rotate circumferentially during use, the probe windows 20 cannot face downwards to the sediment, which affects the measurement, and in this embodiment, a plurality of probe windows 20, for example, three, are circumferentially arranged on the pipe shell 10. The corresponding grooves C1, the first mounting plate 15, the detector 30, and the like are also configured in three groups.
According to the submarine sediment probe 100 in the embodiment of the invention, the groove C1 with the necking groove C11 along the axial direction is arranged on the periphery of the pipe shell 10, so that when sediment passes through the necking groove C11 in the traction process, the submarine sediment probe 100 presses out seawater and is pressed on the outer surface of the probing window 20, the influence of the seawater on the probing is avoided, and the detector 30 can directly and accurately probe the sediment to obtain an accurate probing result.
Example two
Referring to fig. 4, the present embodiment provides a method for detecting a submarine sediment, which includes the following steps:
the submarine sediment probe 100 according to the first embodiment is connected by using the cable 200, and the submarine sediment probe 100 is sunk into the sea floor, so that the groove C1 on the pipe shell 10 of the submarine sediment probe 100 is pressed on the submarine sediment layer;
the submarine sediment probe 100 is pulled to axially advance and the detector 30 is made to look from the window 20 for sediment pressed against the outer surface of the window 20 as required.
Alternatively, referring to fig. 5, the cable 200 is connected to the end of the submarine sediment probe 100 away from the detection window 20, and the submarine sediment probe 100 is obliquely lifted by controlling the length of the cable 200 during the detection, and the end of the detection window 20 is pressed against the submarine sediment layer. By lifting the submarine sediment probe 100 by the cable 200, the submarine sediment probe 100 can pass through different submarine terrains, and the pressing end of the inclined submarine sediment probe 100 can be tightly pressed against the submarine sediment probe 100, so that the pressing degree of the detection window 20 of the submarine sediment probe 100 and the submarine sediment layer is further improved, and the accuracy of the detection result is further improved.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
