Embodiment 1

[0030] As shown in the figure, the seabed survey and sampling device includes a main frame 100, the bottom of the main frame 100 is equipped with a weighted leg 7, the top of the main frame 100 is connected with a steel wire rope 1, and the weighted leg 7 is provided with a weight block to increase the weight of the whole device. The weight is kept at the time of sampling and the device is not propped up. A bracket frame 101 is arranged around the main frame 100, and the protective sleeve frame 4 is arranged between the bracket frame 101 and the main frame 100, and the bracket frame 101 is provided with reinforcing ribs to connect with the main frame 100;

[0031] The middle seat 10 is hinged with a hydraulic cylinder 2 12, and the hydraulic cylinder 2 12 is hinged to the inner corner of the main frame 100. The middle seat 10 is arranged and positioned inside the main frame 100, and the expansion and contraction of the hydraulic cylinder 2 12 can drive the middle seat 10 to be ...

Abstract

Disclosed is a submarine exploration sampling device. The submarine exploration sampling device comprises a main frame, the bottom of the main frame is provided with weight support legs, and the top of the main frame is connected with steel wire cables. The submarine exploration sampling device is characterized in that the circumference of the main frame is provided with a support frame, a protective casing rack is arranged between the support frame and the main frame, and the support frame is provided with reinforcing bars connected with the main frame; hydraulic cylinders II are hinged to amiddle base and to the inner corners of the main frame to arrange and position the middle base inside the main frame, the corners of the middle base are provided with sleeves, vertically moving pipesare arranged inside the sleeves, the tops of the vertically moving pipes are connected with hydraulic cylinders III, and the bottoms of the vertically moving pipes are threadedly connected with sampling pipes. The submarine exploration sampling device has the advantages of overcoming the problem of sampling difficulty in the prior art through reasonable structural design, achieving rapid samplingvia manual control and being high in speed and sampling efficiency and applicable generalized application.

Description

technical field [0001] The invention relates to a seabed survey sampling device and a sampling method thereof, belonging to the technical field of civil survey. Background technique [0002] The physical property parameters of seabed surface sediments, such as the natural water content and natural density of sediments, are indispensable and important parameters for the design and construction of submarine pipelines, cables and other engineering structures directly located on the seabed surface. [0003] At present, the physical performance indicators of these sediments are usually obtained in the following ways: 1. Anchor-type sediment soil collection device, the collection device is dropped into the bottom of the ocean by using the form of anchoring, and the seabed sediment soil is pulled into the device by starting the tugboat, and then Take it ashore and transport it to the laboratory for testing, but this method is very prone to water loss disturbance, resulting in devia...
