Description

Technical Field

[0001] The utility model relates to deep - sea sampling equipment, specifically to a deep - sea automatic sampling operation platform for collecting deep - sea sludge and seabed sediments. Background Art

[0002] After the mid - 20th century, with the development of deep - sea exploration technologies such as sonar, remote control, and underwater robots, it has been possible to more accurately locate and detect the seabed environment, thus providing a better technical basis for seabed sampling.

[0003] With the continuous development of materials science and process technologies, it is now possible to design and manufacture deep - sea samplers that are more resistant to high pressure, corrosion, and low temperature, making seabed sampling possible.

[0004] With the progress of computer technology and data transmission technology, it is more convenient to obtain, transmit, and analyze the data obtained from seabed sampling, providing more possibilities for deep - sea research.

[0005] Many existing samplers are not suitable for operation by an automated system. Moreover, these samplers are complex to operate and difficult to collect multiple samples at one time. At the same time, an automated sampling system also needs to be able to accurately collect samples within a predetermined time and at a predetermined location, or accurately collect samples in a dangerous deep - sea environment. Summary of the Utility Model

[0006] Therefore, the utility model aims to provide a deep - sea automatic sampling operation platform that can accurately collect multiple samples simultaneously within a predetermined depth and a predetermined location range. The utility model also aims to provide an automated system that can be used for deep - sea sampling.

[0007] The technical solution of the utility model is: a deep - sea automatic sampling operation platform, which includes an operation platform main body and an automatic sampler, a sample collection device, and a pump - jet thruster arranged in the operation platform main body;

[0008] The automatic sampler includes a drilling depth main shaft that moves up and down. An axle tube is sleeved outside the drilling depth main shaft. The end of the drilling depth main shaft is connected to a drill chuck. The drill chuck is a claw - shaped structure that expands circumferentially, closes when inside the axle tube, and opens when outside the axle tube;

[0009] The sample collection device includes a rotating gear. A sampling bucket is arranged on the rotating gear. When the drilling depth main shaft moves downward, it extends into the sampling bucket, and the drill chuck grabs the sampling bucket and extends downward out of the operation platform main body.

[0010] Furthermore: The operation platform further includes an image collector, a sonic communication device, a GPS positioning device, a deep - water warning light, and a storage battery.

[0011] Further: There are two drill depth spindles arranged side by side, and a pair of meshing rotating gears. The two drill depth spindles are respectively located above the two rotating gears.

[0012] Further: A number of sampling holes are circumferentially and evenly distributed on the rotating gear. An opening and closing bottom cover is arranged at the bottom of the sampling hole, and the sampling bucket is placed in the sampling hole.

[0013] Further: A total of 4 pump jet thrusters are arranged in the transverse and longitudinal directions in the operation platform main body.

[0014] Further: The pump jet thruster includes a pump push motor, a water storage pipeline, and a spiral fan blade. The pump push motor is drivingly connected to the spiral fan blade. The spiral fan blade is placed in the water storage pipeline. An inlet and an outlet are arranged on the water storage pipeline. The outlet includes a horizontal outlet and a vertical outlet.

[0015] Still further: A rotatable baffle is arranged on the water storage pipeline. When the baffle is turned up, the horizontal outlet is blocked and the vertical outlet is opened; when the baffle is laid flat, the vertical outlet is blocked and the horizontal outlet is opened.

[0016] The utility model samples simultaneously through two samplers, reducing accidental experimental errors; the two rotating gears that fix the sampling bucket rotate at the same speed and in opposite directions, which can maintain overall balance.

[0017] The utility model has a pump jet thruster, which can provide sufficient thrust, enabling the sampler to accurately position and move on the seabed in order to collect samples at different positions.

[0018] Meanwhile, the utility model is also equipped with image acquisition and data recording devices to record the position and other environmental parameters during sampling, providing more information for research.

[0028] To make the technical solutions and advantages of this application clearer, the following will clearly and completely describe the technical solutions of this application in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, rather than all of them. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0029] As Figures 1 to 4 shown, the present utility model discloses a deep-sea automatic sampling operation platform, including an operation platform main body 1, an automatic sampler 2, a sample collection device 3, a pump-jet thruster 4, an image collector 5, an acoustic communication device 6, a GPS positioning device 7, a deep-water warning light 8, and a storage battery 9.

[0030] The outer shell of the operation platform main body 1 is in the shape of a flying saucer to minimize the resistance during underwater travel. The inner part of the outer shell has a hollow cavity, and a flip cover is provided at the top of the outer shell to open the hollow cavity. The automatic sampler 2, the sample collection device 3, and the pump-jet thruster 4 are installed in the hollow cavity. The automatic sampler 2 and the sample collection device 3 are combined for sampling and collection, and the pump-jet thruster 4 is used to push the platform to move forward; an opening is provided at the bottom of the outer shell, which fits with the sample collection device 3 and is used to extend the sampling bucket for sampling.

[0031] The image collector 5 is installed outside the operation platform main body 1, and one camera faces forward and the other faces backward for detecting the underwater environment for sampling. Preferably, it is installed directly below the water outlet of the pump-jet thruster 4. The acoustic communication device 6 is connected to the ground operation equipment and also to the drive motor controllers inside the platform, and is used to control the drive motors through external signals. The GPS positioning device 7 is attached to the outer shell of the operation platform main body for platform positioning. The deep-water warning light 8 is installed on the edge and the upper surface of the operation platform main body for the visual range of the main body. The storage battery 9 is used to supply power to each electrical device of the platform.

[0032] The automatic sampler 2 is an important mechanism in the present utility model. As Figure 5 、 6As shown in the figure, it includes a drilling depth main shaft power system 21, a drilling depth main shaft 22, a drill chuck 23 and a shaft cylinder 24. The drilling depth main shaft power system 21 includes a controller, which communicates with an external acoustic wave communication device 6, sends instructions to the controller through the acoustic wave communication device 6, and controls the start of the drilling depth main shaft power system 21. The drilling depth main shaft power system 21 drives the drilling depth main shaft 22 in any feasible manner so that the drilling depth main shaft 22 can move axially. For example, it can be driven by the principle of a lead screw slider or the principle of a worm and worm gear. In short, as long as the drilling depth main shaft 22 can move axially. The end of the drilling depth main shaft 22 is connected to the drill chuck 23, and the outside of the drilling depth main shaft 22 is sleeved with a shaft cylinder 24. The lower end of the shaft cylinder 24 is tightened. The drill chuck 23 is a claw-shaped structure that expands circumferentially. It is restricted by the shaft cylinder 24. When the drill chuck 23 extends out of the shaft cylinder 24, it opens, and when it retracts into the shaft cylinder 24, it closes. The lower end of the drilling depth main shaft 22 is provided with a drill chuck 23 for connecting with a sampling bucket for sampling.

[0033] The sample collection device 3 is also an important mechanism in the present utility model. As Figure 7 shown, it includes a gear power system 31, a rotating gear 32 and a sampling bucket 33. By the same principle, the gear power system 31 communicates with the external acoustic wave communication device 6, sends instructions to the controller through the acoustic wave communication device 6, and controls the start of the gear power system 31. The gear power system 31 drives the rotating gear 32 in any feasible manner so that the rotating gear 32 can rotate. For example, it can be directly connected to the rotating gear on the gear motor shaft for driving, or by the way of gear meshing transmission. A number of sampling holes are provided on the rotating gear 32, and the sampling holes are circumferentially evenly distributed with the center of the gear as the center. The sampling bucket 33 is placed in the sampling holes. Further, a switchable bottom cover 34 is provided at the bottom of the sampling hole. As Figure 8 shown, the switchable bottom cover 34 is pivotally connected to the bottom of the sampling hole. The switchable bottom cover 34 is in a retracted state to block the bottom opening of the sampling hole in the natural state. When there is no external force, the switchable bottom cover 34 can support the sampling bucket 33. When an external force presses down on the sampling bucket 33, the switchable bottom cover 34 opens, and when the sampling bucket 33 is retracted, the switchable bottom cover naturally retracts. Further, claw grooves are provided on the inner wall of the sampling bucket 33 for the drill chuck 23 to grip.

[0034] The automatic sampler 2 and the sample collection device 3 are arranged vertically. The function of the automatic sampler 2 is to lower the drilling depth main shaft 22 so that the drill chuck 23 extends into the sampling bucket 33, then grabs the sampling bucket 33 and extends it into the water for sampling, and then retracts the sampling bucket 33 into the sampling hole; the function of the sample collection device 3 is to store the sampling bucket 33. A number of sampling holes are provided on the rotating gear 32. By reasonably controlling the rotation speed of the rotating gear 32 and the telescopic speed of the drilling depth main shaft 22, when a certain sampling bucket 33 rotates to below the drilling depth main shaft 22, the drilling depth main shaft 22 can just extend into the sampling bucket 33.

[0035] In the above solution, in order to improve efficiency, the automatic sampler 2 can be provided with two parallel drilling depth main shafts 22, and the sample collection device 3 can be provided with two meshing rotating gears 32. At a certain moment, the two drilling depth main shafts 22 can synchronously grab two sampling buckets 33.

[0036] The pump jet thruster 4 is also an important mechanism in the present utility model. A total of 4 pump jet thrusters are arranged in the horizontal and vertical directions in the middle of the operation platform main body 1 to achieve power balance and omnidirectional movement. As Figures 2 to 4 shown, it includes a pump push motor 41, a water storage pipeline 42, and a spiral fan blade 43. An inlet 44, a horizontal outlet 45, and a vertical outlet 46 are provided on the water storage pipeline 42, and these water outlets are all in the form of grille openings.

[0037] The pump push motor 41 drives the spiral fan blade 43 to rotate. The spiral fan blade 43 is located in the water storage pipeline 42, and there is water in the water storage pipeline 42, which can be stirred by the spiral fan blade 43. The water storage pipeline 42 is evenly distributed in four directions along the operation platform main body 1. By controlling the opening and closing of the horizontal outlet 45 and the vertical outlet 46, the platform can be manipulated to move in different directions.

[0038] Further, the ratio of the inlet to the outlet of the pump jet thruster 4 is 1:2. There is an inlet 44 above the spiral fan blade 43, and there are two outlets at the end of the spiral fan blade 43, one is the horizontal outlet 45 and the other is the vertical outlet 46.

[0039] Still further, a rotatable baffle 47 is provided on the water storage pipeline 42. When the rotatable baffle 47 is turned up, it will block the horizontal outlet 45 and open the vertical outlet 46; when the rotatable baffle 47 is laid flat, it will block the vertical outlet 46 and open the horizontal outlet 45. By controlling the water outlet direction in this way, the platform can be moved in different directions.

[0040] For an underwater automatic sampling operation platform, setting an image collector 5, an acoustic communication device 6, a GPS positioning device 7, a deep water warning light 8, and a storage battery 9 are all conventional settings and will not be introduced in detail here.

[0041] This automatic sampling operation platform can achieve multi-directional sampling at intervals through the pump jet thruster. The sample collection device can store multiple samples, improving the efficiency of deep sea sampling. The automatic sampler can collect deep sea soil samples and bottom mud and grab some animals and plants, increasing the diversity of sampling.

[0042] This automatic sampling operation platform is equipped with an automatic control system, which can independently perform sampling operations according to preset parameters. At the same time, the sampler is equipped with a data recording and transmission system, which can record relevant data during the sampling process and transmit the data to the data receiving device on the ground or on the ship through the acoustic communication device.

[0043] Specifically, for example, when the automatic sampling operation platform sinks to the bottom of the water, after the image transmitted back by the image collector shows contact with the seabed, the automatic sampler is started. At this time, the drilling depth main shaft moves downward and drives the drill chuck into the sampling bucket and expands outward until it tightly holds the sampling bucket. Then, the sampling bucket and the drilling depth main shaft drill downward together for sampling, and the sampling depth is the height of the sampling bucket. After local sampling is completed, the drilling depth main shaft brings back the sampling bucket in the reverse direction. After the drilling depth main shaft is separated from the sampling bucket, the drilling depth main shaft returns to its original position, the rotating gear rotates to move a new sampling bucket under the drilling depth main shaft, and at the same time, the pump spray thruster is started to move the sampling platform. It is closed when the sampler reaches the next sampling point. By setting numbers for the sampling buckets, the numbers, time, and location can be recorded during sampling. After sampling is completed, the automatic sampler and the sample collection device stop working, and the pump spray thruster is started to make the operation platform float to a predetermined position.

[0044] The above are only specific embodiments of the present application, enabling those skilled in the art to understand or implement the present application. However, various equivalent modifications and transformations of these embodiments will be obvious to those skilled in the art. Without departing from the spirit or scope of the present application, the present application will not be limited to these embodiments, but will conform to the scope consistent with the claims of the present application.
