[0026] Specifically, buoyancy tank 10 includes two tank bodies 101, and both tank bodies 101 are hollow, which can ensure that buoyancy tank 10 can float on water surface and provide support for sampling cylinder 20, etc.The two ends of two tank bodies 101 are fixedly connected by connecting portion 102, and connecting portion 102 communicates the interiors of two tank bodies 101, to ensure that the air pressures in the interiors of two tank bodies 101 are consistent, so as to ensure that the buoyancies of two tank bodies 101 are same.A passage is formed between two tank bodies 101 and two connecting portions 102, and the passage is mainly used for sliding rope 40, first pull rope 50, second pull rope 60 and sampling cylinder 20 to pass through.

[0027] Sampling cylinder 20 includes base 201 and cylinder body 202 fixedly arranged on the lower side of base 201, and sliding column 204 is movably connected to the opposite sides of base 201 by rotating shaft 203, and sliding channel is formed on the axis of sliding column 204 and penetrates the two ends of sliding column 204, and sliding column 204 is arranged on sliding rope 40 by sliding channel.

[0028] In order to reduce the influence of air buoyancy in sampling cylinder 20 on sampling cylinder 20 descending, a plurality of through holes 2021 are formed on one end of cylinder body 202 close to base 201, and through holes 2021 are used for exhausting air when sampling cylinder 20 descends, and through holes 2021 are used for draining water when sampling cylinder 20 ascends.Of course, the diameter of through hole is relatively small, to avoid the escape of collected bottom mud sample from through hole as far as possible.

[0029] In order to ensure that the slide 50 can be as vertical as possible in the water, the lower end of the slide 40 is fixedly provided with a hanging cone 401, and the gravity of the hanging cone 401 will pull the slide 40 downward in a substantially vertical manner during sampling; when the hanging cone 401 is lowered to the bottom of the water at the sampling position in a vertical or substantially vertical downward state, the upper end of the slide 40 is fixed on the upper side of the top plate 30, so that the slide 40 between the hanging cone 401 and the lower side of the top plate 30 is in a vertical or substantially vertical state.

[0030] It should be noted that the hanging cone 401 is a lead cone, and when in use, the lead cone gravity makes the slide maintain a vertical state, and the two slides 40 are used for lifting and guiding the sampling cylinder to ensure the sampling position. The lead cone has a large density, and a lead cone with a small volume can provide a large gravity as a pulling force, which can reduce the impact of water flow on the lead cone and can reduce the horizontal position change of the lead cone as much as possible.

[0031] In the embodiment, the top plate 30 is provided with a first pull rope through hole 301, a second pull rope through hole 302, and two slide through holes 303; wherein the two slide through holes 303 are symmetrical about the first pull rope through hole 301, and the line connecting the first pull rope through hole 301 and the second pull rope through hole 302 is perpendicular to the line connecting the two slide through holes 303; the top plate 30 is further provided with four fixed columns 304 corresponding to the first pull rope through hole 301, the second pull rope through hole 302, and the two slide through holes 303; the first pull rope 50, the second pull rope 60, and the two slides 40 are wound and fixed on the corresponding fixed columns 304 in a non-up-and-down moving state.

[0032] Embodiment 2

[0033] As shown in Figures 3-4 In order to ensure the sampling depth of the sampling cylinder 20, the embodiment is different from the embodiment 1 in that the upper side of the base 201 is further provided with a vibration assembly 70, and the vibration assembly is located at the center position of the base. The vibration of the vibration assembly makes the sampling cylinder move into the mud. Specifically, the vibration assembly is a vibration motor. It should be noted that when the vibration motor is arranged on the upper side of the base, the vibration motor is fixedly arranged on the base by bolts, and the vibration motor is connected with the first pull rope movably arranged on the top plate, instead of directly connecting the first rope with the upper side of the base.
