Description

Technical Field

[0001] This utility model belongs to the field of sampling device technology, and more specifically, it relates to an intelligent vibration sampler suitable for complex sea conditions in shallow and medium-water areas. Background Technology

[0002] In the field of marine research, geological surveys in shallow and mid-water areas are crucial for understanding marine geological structure, resource distribution, and ecological environment. Obtaining high-quality seabed sediment samples is an important prerequisite for conducting related research. High-frequency vibration sampling is currently an effective method for sampling sediment geophysical parameters, pollutants, and trace metals in waters such as harbors, estuaries, reservoirs, lakes, wetlands, and shallow seas. It has significant advantages such as minimal sample interference and environmental friendliness. In the complex sea conditions of shallow and mid-water areas, an intelligent vibration sampler is needed to facilitate sampling and processing.

[0003] Based on existing technology, it has been found that existing vibratory samplers, when used, cannot detect the presence of fishing nets or the flatness of the seabed during the lowering process due to the complexity of the seabed conditions. In addition, during the actual sampling process, it is impossible to determine whether the sampling tube of the vibratory sampler is fully inserted into the seabed. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model relates to an intelligent vibration sampler suitable for complex sea conditions in shallow and medium-water areas. This solves the problems of existing vibration samplers, which, due to the complexity of the seabed, cannot detect the seabed conditions during the sampler's descent and cannot determine whether the sampling tube of the vibration sampler is fully inserted into the seabed during actual sampling.

[0005] This utility model provides an intelligent vibration sampler suitable for complex sea conditions in shallow and medium-water areas, achieved through the following specific technical means:

[0006] A smart vibration sampler suitable for complex sea conditions in shallow and mid-water areas includes: a base; a central connecting block inside the base; a camera fixedly mounted on the outer wall of the central connecting block; a pressure sensor fixedly mounted on the outer wall of the central connecting block; an attitude sensor fixedly mounted on the outer wall of the central connecting block; two conduits fixedly mounted on the top of the central connecting block; a gravity tube between the two conduits; guide sleeves fixedly mounted on the two conduits; a vibration motor assembly fixedly mounted on the guide sleeves; connectors fixedly mounted on the ends of the two conduits; a steel cable fixedly mounted at the middle of the connectors; a lightweight cable connected to the vibration motor assembly; a junction box connected to the lightweight cable; an external control terminal electrically connected to the junction box; the steel cable wound on a winch; and a control box electrically connected to the winch's winding assembly.

[0007] Preferably, the two conduits are each configured as a cylindrical rod-shaped structure.

[0008] Preferably, a sampling component is provided at the end of the gravity tube.

[0009] Preferably, the vibration motor assembly is connected to the gravity tube.

[0010] Preferably, the lightweight cable is electrically connected to the camera, pressure sensor, and attitude sensor, respectively.

[0011] Preferably, the junction box is electrically connected to the portable cable.

[0012] Preferably, the winch is equipped with a winding assembly; the winding assembly of the winch is connected to the end of the steel cable.

[0013] The intelligent vibration sampler proposed in this invention, suitable for complex sea conditions in shallow and medium-water areas, has the following beneficial effects:

[0014] 1. The external control terminal is connected to a lightweight cable via a junction box. It can receive real-time images of the seabed environment captured by the camera, pressure data detected by the pressure sensor, and attitude information fed back by the attitude sensor. Operators can intuitively understand the working status of the sampler underwater and the surrounding environment from a safe location away from the sampling site through the external control terminal. At the same time, the external control terminal can also send control commands to equipment such as the vibration motor assembly and winch based on these real-time data to achieve remote and precise control of the sampling operation.

[0015] 2. The gravity tube maintains its stability through gravity. The sampling component at its end, assisted by the vibration motor assembly, can efficiently insert into seabed sediments for sampling. The gravity tube's design utilizes the principle of gravity, allowing it to maintain a relatively stable posture even in complex sea conditions, reducing interference from external factors such as water flow. At the same time, the vibration generated by the vibration motor assembly reduces the resistance when the gravity tube is inserted into the sediment, making the sampling process smoother, improving sampling efficiency and sample integrity. In addition, a lightweight cable is used to transmit the sampling status to an external control terminal in real time for convenient detection of sampling information. Attached Figure Description

The sampling section detects the real-time pressure on the seabed during descent to facilitate exploration of the seabed environment. An attitude sensor 4 is fixed to the outer wall of the central block of base 1. The attitude sensor 4 identifies the angle of the seabed; if the angle is too large, the sampling point needs to be moved. Two guide tubes 5 are fixed to the top of the central block of base 1. The guide tubes 5 assist in the installation and fixation of other structures of the sampling section for ease of use. A gravity tube 6 is provided between the two guide tubes 5. The gravity tube 6 maintains stability through gravity while simultaneously performing sampling through the end sampling assembly. Guide sleeves 7 are fixed to the two guide tubes 5. The guide sleeves 7 are used to secure the vibration motor assembly 8. The guide sleeve 7 is fixed to the gravity tube 6 to facilitate sampling. Connectors 9 are fixed to the ends of the two conduits 5 to ensure stability. A steel cable 10 is fixed to the middle of the connector 9 to connect the sampling part of the sampler to the winch 14 for easy recovery of the sampling part. A lightweight cable 11 is connected to the vibration motor assembly 8. The lightweight cable 11 is used to power the pressure sensor 3, the underwater 360-degree high-definition camera 2, and... The attitude sensor 4 transmits data and power to facilitate its normal operation; the lightweight cable 11 is connected to a junction box 12; the junction box 12 is used to control the lightweight cable 11 in conjunction with the external control terminal 13; the junction box 12 is electrically connected to the external control terminal 13; the external control terminal 13 is used to receive seabed environmental information and send control commands; the steel cable 10 is wound onto the winch 14; the winch 14 is used to wind up the steel cable 10 through the winding assembly to facilitate the recovery of the sampled portion; the winding assembly of the winch 14 is electrically connected to a control box 15; the control box 15 is used to control the operation of the winding assembly of the winch 14.

[0026] Example 2: Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 6 As shown, the two conduits 5 are respectively configured as cylindrical rod-shaped structures.

[0027] A sampling component is provided at the end of gravity tube 6.

[0028] The vibration motor assembly 8 remains connected to the gravity tube 6.

[0029] The lightweight cable 11 is electrically connected to the camera 2, the pressure sensor 3, and the attitude sensor 4, respectively.

[0030] The junction box 12 is electrically connected to the portable cable 11.

[0031] The winch 14 is equipped with a winding assembly; the winding assembly of the winch 14 is connected to the end of the steel cable 10.

[0032] The specific usage and function of this embodiment are as follows:

[0033] In this invention, the winding assembly of the winch 14 is activated, and the steel cable 10 is slowly released under the control of the control box 15, causing the sampling part of the sampler to gradually sink. During the sinking process, the camera 2 captures real-time images of the surrounding environment and transmits the image data to the external control terminal 13 via the lightweight cable 11. The operator can visually observe the seabed conditions, such as water flow speed and the presence of obstacles, on the external control terminal 13. The pressure sensor 3 detects changes in water pressure in real time and transmits the pressure data to the external control terminal 13 via the lightweight cable 11 to determine the depth of the sampler. The attitude sensor 4 monitors the attitude of the sampler in real time and transmits the attitude data to the external control terminal 13. If the attitude sensor 4 detects that the seabed angle is too large and exceeds the preset range, the external control terminal 13 will issue an alarm. The operator can then fine-tune the sampler position by controlling the winch 14 to move it to a suitable sampling point according to the actual situation. When the sampler reaches the predetermined seabed sampling position and the attitude sensor 4 returns a positive value, the sampler will be successfully sampled. Once the requirements are met, the external control terminal 13 sends a command to the vibration motor assembly 8 to start the vibration motor. The vibration motor assembly 8 then begins to work, applying vibration to the gravity tube 6. Under the combined action of gravity and vibration, the sampling component at the end of the gravity tube 6 gradually inserts into the seabed sediment. During this process, the camera 2 continuously captures real-time footage of the gravity tube 6 inserting into the sediment and transmits it to the external control terminal 13. The operator can judge the sampling progress based on the footage. After sampling is completed, the external control terminal 13 sends a command to the control box 15 of the winch 14 to control the winding assembly to begin winding the steel cable 10, slowly recovering the sampling portion of the sampler to the sea surface. During the recovery process, the camera 2, pressure sensor 3, and attitude sensor 4 continue to work, transmitting relevant data to the external control terminal 13 so that the operator can monitor the sampler's status in real time. After the sampler returns to the ship, the components are carefully disassembled, and the sediment sample from the sampling component at the end of the gravity tube 6 is extracted for subsequent analysis and research.
