For the convenience of understanding of the present scheme, the sampling process is described by taking a surface layer sample as an example:

connecting a steel wire rope of the winch with a mud sampler, checking whether the steel wire rope is firm or not, and simultaneously measuring the depth of water at a sampling point;

the mud sampler is placed into water by a winch which is driven at a slow speed, and after the mud sampler is stabilized, the mud sampler is placed at a constant speed to be 3-5 m away from the seabed, and then is fully lowered to the seabed, so that mud enters the mud sampler by the falling impact force;

after the mud is extracted, slowly lifting the mud extractor to the water surface after the mud extractor is separated from the bottom, then slowly lifting the mud extractor to the water surface, stopping when the mud extractor is higher than a ship board, and slightly lowering the mud extractor to a sample receiving plate;

opening an ear cover at the upper part of the mud sampler, slightly inclining the mud sampler to enable accumulated water at the upper part to slowly flow out, and if the mud sampler is washed by seawater in the lifting process, so that a sample is excessively lost or sediment is excessively soft and falls off too violently, so that the sediment overflows from the ear cover, re-mining is required;

and after the sample is treated, removing residual sediments in the mud sampler, and washing the sediment clean for later use.

The device for marine sediment sample acquisition and water depth measurement according to the embodiment of the utility model is introduced below with reference to fig. 1, fig. 2 and fig. 3, and belongs to a box-type mud sampler, and the device specifically includes:

the upper end and the lower end of the box body 1 are provided with openings;

the anti-leakage mud bucket 5 is rotatably installed on any one mud bucket 2 and is linked with the two mud buckets 2, when the two mud buckets 2 are rotated to abut against each other, the linked anti-leakage mud bucket 5 is rotated to the abutting joint of the two mud buckets 2, and when the two mud buckets 2 are unfolded, the linked anti-leakage mud bucket 5 is unfolded.

In this embodiment, the box body 1 is a square body, the opening at the upper end of the box body 1 is an observation port, and a switch door 13 (i.e. an ear cover) hinged with a switch can be arranged; the opening at the lower end of the box body 1 is a sludge inlet. The two mud buckets 2 can be identical in shape and symmetrically arranged on two sides of the box body 1, and the guide frame 3 serves as a guide structure, so that the pull rod assembly 4 can stably move up and down.

Specifically, the pull rod assembly 4 is provided with a lifting handle 44, and the steel wire rope is connected to the lifting handle 44, so that the device (i.e. the mud sampler) is lowered, wherein the pull rod assembly 4 is not moved upwards in the lowering process, when mud is sampled, the mud sampler completely releases the tension on the pull rod assembly 4 at a distance of 3-5 m from the seabed, so that the box body 1 is lowered to the seabed at full speed, mud enters the box body 1 from an opening at the lower end of the box body 1 through the descending impact force, then the pull rod assembly 4 is moved upwards when the pull rod assembly 4 is pulled up, and the two mud taking hoppers 2 are linked to rotate downwards and abut against each other to seal the opening at the lower end of the box body 1, so that the mud is sealed in the box body 1; meanwhile, the anti-leakage mud bucket 5 is used for preventing the mud from leaking from the abutting part of the two mud buckets 2 in an abutting mode, and therefore the mud taking efficiency is improved.

Further, at the in-process that the mud sampler transferred, transfer the degree of depth and also need monitor to conveniently judge at what position release pull rod assembly 4, wire rope connects on the handle 44 that sets up on pull rod assembly 4, can set up the length sign on wire rope, can know the degree of depth of transferring of mud sampler through observing the length sign on the wire rope.

In an embodiment, as shown in fig. 1, 2 and 3, the pull rod assembly 4 is provided with a positioning portion 41, the guide frame 3 is provided with a position-limiting hook 31 which rotates eccentrically, when the position-limiting hook 31 is hooked with the positioning portion 41 in a matching manner, the pull rod assembly 4 is pulled upwards to be limited and forms a lowering state of the device before mud taking, when the pulling force of the pull rod assembly 4 is released, the position-limiting hook 31 is eccentrically overturned due to self weight, and when mud taking is formed, the mud sampler is lowered to a mud taking position due to self weight.

In this embodiment, in the process of using the steel wire rope to lower the mud sampler, the steel wire rope is connected with the pull rod assembly 4 and is influenced by gravity, the pull rod assembly 4 is pulled up in the natural state, therefore, the positioning part 41 is arranged on the pull rod assembly 4, the guide frame 3 is provided with the eccentric rotating limiting hook 31, the limiting hook 31 comprises a hook block 311 and an eccentric block 312, in the process of placing the mud sampler down, the hook block 311 is hooked on the positioning part 41 in advance, and the pull force of the pull rod assembly 4 lifted by the steel wire rope can stably hook the hook block 311 and the positioning part 41 tightly in the natural state, so that the pull rod assembly 4 is prevented from moving upwards, and at this moment, namely, the lowering state of the device before taking mud is achieved. When the eccentric block 312 is 3-5 m away from the seabed, the pulling force on the pull rod assembly 4 is released, the acting force between the hook block 311 and the positioning part 41 is lost, and the hook block 311 rotates and is separated from the positioning part 41 under the action of the gravity of the eccentric block 312; at the moment, the mud sampler descends to a mud taking state of a mud taking position under the self-weight. After taking mud, when the steel wire rope pulls the pull rod assembly 4 upwards, the pull rod assembly 4 does not interact with the limiting hook 31 any more, but the pull rod assembly 4 moves upwards completely and drives the two mud buckets 2 to abut against each other.

In an embodiment, the first extension rod 21 is fixedly disposed at the rotation point of each of the two ends of the mud bucket 2, the pull rod assembly 4 includes linkage sides symmetrically disposed, each linkage side includes a vertical rod 42 and two connecting rods 43, one end of each of the two connecting rods 43 is rotatably connected to the lower end of the vertical rod 42, and the other end of each of the two connecting rods 43 is rotatably connected to the corresponding extension end of the first extension rod 21.

Conversely, it can be understood that when the pull rod assembly 4 moves upwards, i.e. the vertical rod 42 moves upwards, the two mud buckets 2 can rotate and abut against each other.

In one embodiment, the guiding frame 3 includes two fixing sleeves 32 respectively located at two sides of the upper end of the box 1, and the vertical rods 42 at two sides of the pull rod assembly 4 are respectively slidably fitted in the two fixing sleeves 32.
