[0001] The present invention relates to the technical field of underwater samplers, and particularly to a device for cutting columnar samples and bottoming of an underwater sampler. Background Art

[0002] A columnar sampler is a key device for obtaining bottom sediments, which is widely used in fields such as underwater scientific research, environmental monitoring, and resource development. With the continuous in-depth research on ecological and environmental changes, the demand for efficient and accurate sampling equipment is increasing day by day. During underwater sampling, the integrity and accuracy of columnar samples are crucial. Existing samplers directly collect columnar samples by inserting the sampling cylinder into the sediment. However, the collected columnar samples are still connected to the source sample environment, and it is easy for the columnar samples to fall off when transferred to the sampling cylinder, resulting in damage to the integrity of the columnar samples. There are certain deficiencies in the cutting and bottoming of columnar samples. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a device for cutting columnar samples and bottoming of an underwater sampler, which solves the problems that there are certain deficiencies in the cutting and bottoming of columnar samples in the prior art, which may lead to contamination or falling off of columnar samples.

[0004] To solve the above technical problems, the present invention provides the following technical solutions:

[0005] A device for cutting columnar samples and bottoming of an underwater sampler, including a cutting and bottoming mechanism provided in the sampling cylinder, which quickly cuts the columnar sample and bottoms it after sampling. The cutting and bottoming mechanism includes a wire-releasing groove opened on the inner wall of the bottom of the sampling cylinder, a cutting wire rope arranged in the wire-releasing groove, a winding component arranged on the sampling cylinder, and a bottoming component installed in the wire-releasing groove. A moving track is fixed on one side of the sampling cylinder. The winding component drives the cutting wire rope to move from the wire-releasing groove to the moving track to cut the columnar sample, and at the same time, the cutting wire rope drives the bottoming component to hold the cut columnar sample.

[0006] As a further optimized solution of the present invention, the cutting and bottoming mechanism further includes a buckle component provided at the bottom of the sampling cylinder for restricting the position of the cutting wire rope. The buckle component includes a plurality of plastic wire groove buckles distributed in a circumferential array on the inner side of the bottom of the sample cylinder, and one of the plastic wire groove buckles is located on one side of the recovery port at the bottom of the moving track.

[0007] As a further optimized solution of the present invention, connecting blocks are respectively fixed on the upper and lower sides of the plastic wire groove buckle by bolts, and the connecting blocks are fixed to the inner wall of the sampling cylinder.

[0008] As a further optimization solution of the present invention, the bottom support component includes a bottom support net arranged inside the wire releasing groove, and a pulling wire rope fixed on the bottom support net and fixed to the cutting wire rope.

[0009] As a further optimization solution of the present invention, the winding component includes a motor fixed on the top of the sampling cylinder, a wire harness turntable fixed on the output end of the motor, and the winding end at the top of the cutting wire rope is fixed on the wire harness turntable.

[0010] As a further optimization solution of the present invention, an anti - detachment component for preventing the collected columnar sample from falling off is further arranged inside the sampling cylinder, and the anti - detachment component includes a plurality of irregularly distributed falling - off blocking plates arranged on the inner wall of the sampling cylinder.

[0011] As a further optimization solution of the present invention, a rotating seat fixed to the sampling cylinder is rotatably arranged at one end of the falling - off blocking plate.

[0012] As a further optimization solution of the present invention, a connecting bracket is fixed on the top of the sampling cylinder, four transmission rods distributed in a rectangle are fixedly arranged on the top of the connecting bracket, and a force - acting plate for connecting a hydraulic driving part is fixedly installed on the top of the four transmission rods.

[0013] By means of the above - mentioned technical solution, the present invention provides an underwater sampler for cutting and bottom - supporting columnar samples. Compared with the prior art, it has at least the following beneficial effects:

[0014] 1. The present invention cuts the collected columnar sample in the sampling cylinder by setting a cutting and bottom - supporting mechanism. After the sampling cylinder completes the sampling of the columnar sample, the cutting wire rope is wound up by the winding component. The cutting wire rope comes out of the wire releasing groove, cuts and separates the columnar sample inside the sampling cylinder from the sample source environment, making it have an obvious boundary, so as to reduce the attracting effect of the sample source environment on the columnar sample inside the sampling cylinder, effectively avoiding damage to the columnar sample during the collection process.

[0016] 3. The present invention restricts the columnar sample in the sampling cylinder by setting an anti - detachment component. During the up - and - down movement of the sampling cylinder, the friction and gravity of the columnar sample are utilized to drive the detachment - blocking plate to flip at the rotating shaft, so as to prevent the columnar sample from falling off the sampling cylinder, improve the success rate of sampling the columnar sample.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] First Embodiment

[0032] As a marine scientific research device for collecting samples of submarine sediments such as sediment, rock, sedimentary layers, etc., the deep-sea column sampler can vertically insert into the seabed through a long tubular structure and extract continuous sediment samples within a certain depth range. Since the collected columnar samples are connected in the sediment, it is easy for the columnar samples to flow or be contaminated when transferring the sampling cylinder 1. In order to prevent the columnar samples from being lost or contaminated during the rising process and ensure the integrity of the collected columnar samples, referring to Figure 1 - Figure 4 , this embodiment provides a cutting and bottom-supporting device for columnar samples of an underwater sampler, which is composed of a sampling cylinder 1, a connecting bracket 2, a cutting and bottom-supporting mechanism 5 and an anti-detachment component 58. When sampling, the sampling cylinder 1 vertically inserts into the sediment, and the sediment in the sampling cylinder 1 can be sampled.

[0033] To ensure the stability of the connection of the sampling cylinder 1, four transmission rods 3 distributed in a rectangle are fixedly arranged at the top of the connecting bracket 2. A force acting plate 4 for connecting a hydraulic driving member is fixedly installed at the top of the four transmission rods 3. The output end of the external hydraulic driving member is fixed to the force acting plate 4, and the output end of the hydraulic driving member pushes the transmission rods 3 and the connecting bracket 2 to move through the force acting plate 4, thereby pushing the sampling cylinder 1 to move for sampling.

[0034] The cutting and bottom-supporting mechanism 5 is arranged on the sampling cylinder 1, and quickly cuts and bottoms the columnar sample after the sampling cylinder 1 samples. The cutting and bottom-supporting mechanism 5 includes a wire-releasing groove 51 opened on the inner wall of the bottom of the sampling cylinder 1, a cutting steel wire rope 52 arranged inside the wire-releasing groove 51 and with its movable end fixed to the sampling cylinder 1. A movement track 53 is welded on one inner wall of the sampling cylinder 1. The movement track 53 is a vertically arranged pipe. The cutting steel wire rope 52 moves along the movement track 53. A recovery port 54 matching the cutting steel wire rope 52 is arranged at the bottom of the movement track 53. The cutting steel wire rope 52 enters the movement track 53 through the recovery port 54. When the cutting steel wire rope 52 is wound up, the cutting steel wire rope 52 slides inside the movement track 53.

[0035] To ensure the stability of the cutting wire rope 52 during winding, a winding component 55 for pulling the cutting wire rope 52 to cut the columnar sample is provided on the sampling cylinder 1. The winding component 55 includes a motor 551 fixed to the top of the sampling cylinder 1 and a wire harness turntable 552 fixed to the output end of the motor 551. The winding end at the top of the cutting wire rope 52 is fixed to the wire harness turntable 552. When the cutting wire rope 52 is wound by the winding component 55, the cutting wire rope 52 moves out from the wire release groove 51 to cut the columnar sample. At the same time, the cutting wire rope 52 drives the bottom support component 56 to hold the cut columnar sample.

[0036] Second Embodiment

[0037] To ensure the stability of the cutting wire rope 52 stored in the wire release groove 51 and prevent the cutting wire rope 52 from detaching during sampling, referring to Figure 3 , Figure 4 and Figure 6 , in this embodiment, based on the first embodiment, a buckle component 57 for restricting the position of the cutting wire rope 52 is provided at the bottom of the sampling cylinder 1. The specific implementation method is that the buckle component 57 includes four plastic wire groove buckles 571 distributed in a circumferential array on the inner side of the bottom of the sample cylinder. One of the plastic wire groove buckles 571 is located at the bottom of the recovery port 54, which is the No. 1 position. The remaining positions are the No. 2 position, the No. 3 position, and the No. 4 position in a clockwise direction starting from the No. 1 position. Connecting blocks 572 are respectively fixed to the upper and lower sides of the plastic wire groove buckle 571 by bolts, and the connecting blocks 572 are fixed to the inner wall of the sampling cylinder 1. The cutting wire rope 52 is placed in a ring shape in the wire release groove 51.

[0038] When the cutting wire rope 52 is wound, the diameter of the annular cutting wire rope 52 in the wire release groove 51 gradually decreases. It moves along the movement track 53 through the recovery port 54. The cutting wire rope 52 is drawn out from the wire release groove 51 and sequentially drawn out from the No. 4 position, the No. 2 position, and the No. 3 position. When the cutting wire rope 52 is drawn out from each position, it pushes out the corresponding plastic wire groove buckle 571 and finally comes out from the No. 1 position and enters the recovery port 54, thereby cutting the columnar sample in the sampling cylinder 1 from the sediment.

[0039] To prevent the loss or contamination of the columnar sample during the ascending process and ensure the integrity of the collected columnar sample, a bottom support component 56 for holding the cut columnar sample is provided inside the wire pay-out groove 51. The bottom support component 56 includes a bottom support net 561 disposed inside the wire pay-out groove 51, and a pulling wire rope 562 fixed to the bottom support net 561 and fixed to the cutting wire rope 52. The cutting wire rope 52 drives the bottom support net 561 through the pulling wire rope 562. While the cutting wire rope 52 cuts the sample, the bottom support net 561 for the columnar sample gradually comes out from the 4th position, 2nd position, and 3rd position under the action of the pulling wire rope 562, and finally reaches the 1st position, realizing the bottom support of the sample at the cutting opening of the columnar sample inside the sampling cylinder 1, preventing the columnar sample from quickly detaching from the sampling cylinder 1. Among them, the bottom support net 561 is all connected together through the pulling wire rope 562 to ensure the synchronous movement of the bottom support net 561.

[0040] Third Embodiment

[0041] To prevent the columnar sample from falling off from the sampling cylinder 1, in order to prevent the falling off of the columnar sample, referring to Figure 5 , on the basis of the second embodiment, an anti-falling-off component 58 for preventing the collected columnar sample from falling off is further provided inside the sampling cylinder 1 in this embodiment. The specific implementation manner is that the anti-falling-off component 58 includes a plurality of irregularly distributed falling-off blocking plates 581 provided on the inner wall of the sampling cylinder 1, and a rotating seat 582 fixed to the sampling cylinder 1 is rotatably provided at one end of the falling-off blocking plate 581.

[0042] When the sampling cylinder 1 descends and inserts into the sediment layer for sample sampling, due to the action of friction force, the sample falling-off blocking plate 581 on the rotating seat 582 turns upward and gets as close as possible to the inner wall of the sampling cylinder 1 to facilitate the entry of the columnar sample into the sampling cylinder 1. After sampling is completed, under the action of hydraulic pressure, the sampling cylinder 1 ascends and leaves the deep-sea source sample environment. Due to the action of sample friction force and gravity during the ascending process of the columnar sample inside the sampling cylinder 1, the sample falling-off blocking plate 581 turns downward along the rotating seat 582, so that the upper large-area plate of the sample falling-off blocking plate 581 is in direct contact with the sample to reduce the falling-off state of the sample and realize the function of preventing the columnar sample from falling off.

[0043] The present invention winds up the cutting wire rope 52 through the winding component 55. The cutting wire rope 52 comes out from the wire pay-out groove 51. By providing the bottom support component 56, the collected columnar sample is stably held inside the sampling tube. After the cutting wire rope 52 cuts the columnar sample, the bottom support net 561 is pulled by the pulling wire rope 562 to cover the bottom of the sampling cylinder 1, cutting off and separating the columnar sample inside the sampling cylinder 1 from the sample source environment, creating an obvious boundary to reduce the attracting effect of the sample source environment on the columnar sample inside the sampling cylinder 1.

[0044] During the actual use of the device, the force application plate 4 pushes the transmission rod 3 and the connecting bracket 2 downward. The connecting bracket 2 pushes the sampling cylinder 1 downward to insert it into the sediment layer for sample sampling. Due to the action of friction, the sample shedding blocking plate 581 rotates upward on the rotating seat 582 and gets as close as possible to the inner wall of the sampling cylinder 1 to facilitate the entry of the columnar sample into the sampling cylinder 1. Then, the motor 551 is started. The output shaft of the motor 551 drives the wire harness turntable 552 to rotate. The wire harness turntable 552 winds up and cuts the cutting wire rope 52. The cutting wire rope 52 slides within the movement track 53 through the recovery port 54;

[0045] The cutting wire rope 52 gradually comes out from the 4th position, 2nd position, and 3rd position. The cutting wire rope 52 respectively breaks four plastic card wire groove buckles 571. At the same time, the cutting wire rope 52 disengages from the wire releasing groove 51 and finally comes out from the 1st position and enters the recovery port 54, cutting the columnar sample in the sampling cylinder 1 from the sediment. At the same time, the cutting wire rope 52 drives the bottom net 561 by pulling the wire rope 562, so that the bottom net 561 gradually comes out from the 4th position, 2nd position, and 3rd position and finally reaches the 1st position, realizing the sample bottoming at the cutting opening of the columnar sample inside the sampling cylinder 1 and preventing the columnar sample from quickly detaching from the inner side of the sampling cylinder 1, thereby realizing the entire sampling process.
