Embodiment 1

[0043] figure 1 It is a structural schematic diagram of the seabed sediment probe 100 in Embodiment 1 of the present invention; figure 2 yes figure 1 view of the internal structure of figure 2 for figure 1 Sectional view along line A-A (some structures are hidden and not shown). Please refer to figure 1 (for coordination see figure 2 , image 3 ), the seabed sediment probe 100 in this embodiment includes a casing 10 and a detector 30. The outer peripheral surface of the tube case 10 has a radially concave groove C1 extending along the axial direction of the tube case 10 . And one end of the groove C1 along its axial direction is a shrinking groove C11 whose cross-section gradually decreases. The casing 10 has a viewing window 20 located at the smaller cross-sectional end of the bottom surface P0 of the shrinking groove C11 . The detector 30 is disposed in the casing 10 and faces the viewing window 20 .

Embodiment 2

[0051] See Figure 4 , the present embodiment provides a method for detecting seabed sediments, which includes the following steps:

[0052] Use the cable 200 to connect the seabed sediment probe 100 in Embodiment 1, and sink the seabed sediment probe 100 into the seabed, so that the groove C1 on the casing 10 of the seabed sediment probe 100 is pressed against the seabed sediment layer W1;

[0053] Pull the seabed sediment probe 100 forward along the axis, and make the detector 30 inspect the sediment pressed on the outer surface of the window 20 from the window 20 as required.

[0054] Optionally, see Figure 5 , the cable 200 is connected to the end of the seabed sediment probe 100 away from the viewing window 20, and during the detection process, the length of the cable 200 is controlled to tilt the seabed sediment probe 100, and the end where the viewing window 20 is located is pressed against the seabed sediment Layer W1. By making the cable 200 lift the seabed sedime...

Abstract

The invention relates to the field of submarine detection technologies, and provides a probe and a detection method for submarine sediments. By the aid of the probe and the detection method, the problem of inaccurate detection results of probes for submarine sediments in the prior art can be solved. The probe for the submarine sediments comprises a shell and detectors. Radially concave grooves are formed in the outer peripheral surface of the shell and are perforated along the axial direction of the shell. A necked groove with a gradually reduced cross section is arranged at an end of each groove along the axial direction of the groove. The shell is provided with vision windows, and the vision windows are positioned at the small section ends of the groove bottom surfaces of the necked grooves. The detectors are arranged in the shell and directly face the vision windows. The probe and the detection method have the advantages that influence of seawater on detection can be prevented, the sediments can be directly accurately detected by the detectors, and accordingly accurate detection results can be obtained.

Description

technical field [0001] The invention relates to the technical field of seabed detection, in particular to a seabed sediment probe and a detection method. Background technique [0002] Seabed sediment is an important part of the ocean, and it is the interface between seawater and the deep seabed. The study of seabed sediments can provide important information on the formation and storage conditions of seabed minerals such as petroleum. At the same time, seabed sediments are a good record of geological history and are of great significance for understanding the formation and evolution of the ocean. Therefore, more and more attention has been paid to the detection of seabed sediments. Optical detection is a common detection method. [0003] However, the seawater between the seawater and the sediment will affect the result of optical detection, making the detection result inaccurate. Contents of the invention [0004] The invention aims to provide a seabed sediment probe to...
