A sampling-type high-efficiency detection device for marine sediments

Abstract

The present invention discloses a sampling-type high-efficiency detection device for marine sediments, comprising a main floating plate, a second fixed seat and a gantry. The present invention starts a second motor to drive a rotating column and a winding roller to rotate, so that the winding roller loosens the wound sling, so that the sampler falls into the water due to its own gravity until it sinks to the seabed. After the sampler sinks to the seabed, the sampler will generate pressure on the auxiliary support rod due to its own gravity, so that the auxiliary support rod presses the compression spring downward, so that the pressure rod connected to the pressure plate drives the sealing plate to retract toward the sampling barrel to open the bottom end of the sampling barrel, and due to the influence of the sampler's own gravity, the bottom end of the sampling barrel is inserted into the seabed sediment. At this time, the fourth motor is started again to drive the threaded sampling rod to rotate, so that the seabed sediment enters the sampling barrel for rapid sampling. The positioning cone can maintain the stability of the equipment when the sampler is sampling, and can be maintained on an uneven seabed in conjunction with the compression spring to maintain the stability of the equipment.

Technical Field

[0001] The present invention relates to the field of marine engineering technology, in particular to a sampling-type high-efficiency detection device for marine sediments. Background Art

[0002] Marine sediments are a general term for seafloor deposits formed by various marine sedimentary processes. These are materials deposited on the seafloor using seawater as a medium. Sedimentation can generally be divided into three distinct processes: physical, chemical, and biological. Because these processes often do not occur in isolation, sediments can be considered geological bodies formed by a combination of these processes.

[0003] The ocean is a vital component of the global geological structure and a natural laboratory for modern sedimentation. The seabed holds abundant mineral resources, providing a crucial source of future resources for humanity. Marine environmental geology and hazard geology are directly related to human production and daily life. Marine sediments are a major research area in marine geology. Within the marine ecosystem, marine sediments represent a vast reservoir, recording a wealth of information on changes in the natural marine environment and the impacts of shifting patterns and intensities of human activities on the environment.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1

[0032] Please refer to Figure 1-8The shown device is a sampling-type efficient detection device for marine sediments, comprising a main floating plate 1, a second fixed seat 4 and a gantry 7. Two groups of auxiliary floating plates 3 are fixedly connected on both sides of the main floating plate 1 through four groups of connecting columns 2. A first slide groove 101 is provided inside the top of the main floating plate 1. A sliding rod 102 is fixed inside the first slide groove 101, and the sliding rod 102 passes through the sliding hole 702. The sliding hole 702 is provided inside the slider 701. The slider 701 is fixedly welded to the bottom of the gantry 7. A connecting plate 703 is fixedly welded on the inside of the gantry 7, and an adjusting stud 401 is passed through the internal thread of the threaded hole 704 inside the connecting plate 703. One end of the adjusting stud 401 passes through the inside of the first fixed seat 105, and the other end of the adjusting stud 401 passes through the second fixed seat 4 and one end extends to be connected to the first Belt pulley 402, the first belt pulley 402 is connected to the second belt pulley 501 through the first transmission belt 403, the second belt pulley 501 is connected to an output end of the first motor 5, the first motor 5 adopts a dual-axis motor disclosed in CN112583220B, the first motor 5 drives the adjusting screws 401 and 604 to rotate respectively through the first transmission belt 403 and the second transmission belt 503, the inner side of the gantry 7 is located above the connecting plate 703 and is penetrated by a rotating column 705, the outside of the rotating column 705 is welded with a winding roller 706, and the outside of the winding roller 706 is wound with a sling 709, one end of the sling 709 is connected to the winding roller 706, and the other end of the sling 709 is hung with a sampler, and a rotating block 8 is installed on the top of the gantry 7, and the sling 709 passes through the pulley 804 inside the rotating block 8.

[0033] In this embodiment, by starting an output end of the first motor 5, the adjusting stud 401 can be driven to rotate through the first transmission belt 403, so as to adjust the position of the gantry 7. The gantry 7 is kept stable by the slider 701 welded at the bottom thereof and the sliding hole 702 provided inside the slider 701. Since the slider 701 passes through the first slide groove 101, and the sliding rod 102 fixedly provided in the first slide groove 101 passes through the sliding hole 702, the slider 701 can be cooperated with to maintain the stability of the gantry 7 during displacement and stop, thereby ensuring the safety of sampling. After the gantry 7 is close to one side of the main floating plate 1, the third motor 801 is started to drive the limit connecting block 802 By rotating, the angle of the diagonal support rod 803 is adjusted, and the pulley 804 drives the sampler 8 hanging at the lower end of the sling 709 to rotate to the outside of the main floating plate 1, which is convenient for the sampler 1 to fall into the water and sink to the seabed for sampling. The adjustment is convenient, and the sampler 9 can be conveniently hung on the detection platform 6. By starting the other output end of the first motor 5, the forward and reverse screws 604 can be driven to rotate through the second transmission belt 503, so that the two sets of nut blocks 603 are displaced in opposite phases, thereby adjusting the height of the detection platform 6. When testing is needed, the detection platform 6 is raised, and the sampler 9 is placed on the detection platform 6 under the action of the rotation block 8 driven by the third motor 801, which facilitates testing and improves testing efficiency.

[0034] Please refer to Figure 1 and Figure 2 As shown, an output end of the first motor 5 away from the second belt pulley 501 is connected to the third belt pulley 502, and the third belt pulley 502 is connected to the fourth belt pulley 606 through the second transmission belt 503. The fourth belt pulley 606 is welded to the outside of the forward and reverse screw rods 604, and the two ends of the forward and reverse screw rods 604 respectively pass through the interior of the two groups of first fixed bearings 605, and the first fixed bearings 605 are fixedly installed inside the first drainage hole 103. The first drainage hole 103 is opened at the top of the main floating plate 1, and the external thread of 604 is engaged with two groups of nut blocks 603. The two groups of nut blocks 603 are respectively hinged to one end of four groups of hinged rods 602, and the ends of the four groups of hinged rods 602 away from the nut blocks 603 are hinged to the bottom of the detection platform 6 through the first fixed block 601.

[0035] In this embodiment, by starting the first motor 5, the adjusting stud 401 can be driven to rotate via the first transmission belt 403, thereby adjusting the position of the gantry 7 so that the gantry 7 is close to one side of the main floating plate 1, and then the third motor 801 is started to drive the rotating block 8 to rotate, thereby adjusting the angle of the diagonal support rod 803, so that the sling 709 passing through the pulley 804 is located on the outside of the main floating plate 1, which is convenient for the sampler 9 to fall into the water for sampling. Moreover, since the first motor 5 adopts a dual-axis motor, the first motor 5 can respectively drive the adjusting stud 401 and the forward and reverse screw 604 to rotate. By starting one output end of the first motor 5, the forward and reverse screw 604 can be driven to rotate, so that the two sets of nut blocks 603 threadedly engaged with the forward and reverse screw 604 are displaced in opposite phases, thereby adjusting the height of the detection platform 6. When needed, the detection platform 6 can be raised, and when not in use, the detection platform 6 can be lowered, which not only improves detection efficiency but also effectively utilizes the device space.

[0036] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 8 As shown, a second motor 707 is installed inside the upper end of one side of the gantry 7, the output end of the second motor 707 is connected to one end of the rotating column 705, and one end of the rotating column 705 is penetrated by a second fixed bearing 708, and the second fixed bearing 708 is installed at the front end of the second motor 707, and a third motor 801 is installed inside the top of the gantry 7, the output end of the third motor 801 is connected to a limited connection block 802, and one end of the limited connection block 802 is limited inside the top of the gantry 7, and the end of the limited connection block 802 away from the third motor 801 is connected to the rotating block 8, and two groups of diagonal support rods 803 are fixedly welded to one side of the two groups of rotating blocks 8, and a pulley 804 is penetrated and installed between the ends of the two groups of diagonal support rods 803 away from the rotating block 8.

[0037] In this embodiment, by starting the second motor 707, the rotating column 705 and the roller 706 can be driven to rotate, so that the sling 709 wrapped around the outside of the roller 706 is loosened. Since the sling 709 passes through the pulley 804 arranged between the diagonal support rods 803, the sling 709 can vertically drive the sampler 9 to sink into the water and move vertically toward the seabed under the action of the pulley 804, so that the sampler 9 can fall smoothly to the seabed. Since a positioning cone 905 is provided at the bottom of the sampler 9, it can play a certain role in expelling marine organisms and protecting the sampler 9. In addition, a monitoring probe 911 is provided at the bottom of the sampler 9 to facilitate monitoring and observation of the sinking and sampling of the sampler 9.

[0038] Please refer to Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, a sampling tube 901 is installed at the bottom of the sampler 9, and the bottom of the sampler 9 is located outside the sampling tube 901 and is fixed with four groups of auxiliary support rods 902. The bottoms of the four groups of auxiliary support rods 902 are all connected with compression springs 903. The bottoms of the compression springs 903 are fixedly connected with pressure plates 904. The bottoms of the four groups of pressure plates 904 are all provided with positioning cones 905, which can make the sampler more stable on the seabed. The inner sides of the four groups of pressure plates 904 are all connected with pressure rods 906. The four groups of pressure rods 906 are away from the pressure plates 904. One end is connected to the bottom of the sealing plate 907. There are four groups of sealing plates 907, and the four groups of sealing plates 907 are hinged to the bottom of the sampling tube 901. A threaded sampling rod 909 runs through the interior of the sampling tube 901, and one end of the threaded sampling rod 909 is connected to the output end of the fourth motor 908. The fourth motor 908 is sealed and a battery for powering the motor is provided in the sealing box. The fourth motor 908 is sealed and installed on the top of the sampler 9. The bottom of the sampler 9 is sealed and installed with a monitoring probe 911.

[0039] In this embodiment, after the sampler 9 sinks to the seabed, the sampler 9 will generate pressure on the auxiliary support rod 902 due to its own gravity, causing the auxiliary support rod 902 to press the compression spring 903 downward, thereby causing the pressure rod 906 connected to the pressure plate 904 to drive the sealing plate 907 to shrink and fold into the sampling tube 901 to open the bottom end of the sampling tube 901, and due to the influence of the sampler 9's own gravity, the bottom end of the sampling tube 901 is inserted into the seabed sediment. At this time, the fourth motor 908 is started again to drive the threaded sampling rod 909 to rotate (due to the high sampling efficiency, even when the fourth motor 908 is working, it will not generate a lot of heat), so that the seabed sediment Enter the sampling tube 901 to quickly sample. The positioning cone 905 can maintain the stability of the equipment when the sampler 9 is sampling, and cooperate with the compression spring 903 to maintain the stability of the equipment even on an uneven seabed. After the sampling is completed, the second motor 707 is started to drive the roller 706 to rotate, so that the sling 709 lifts the sampler 9. At this time, the gravity of the sampler 9 is offset by the sling 709, and the compression spring 903 recovers under no pressure, thereby driving the pressure rod 906 to move downward, so that the pressure rod 906 drives the sealing plate 907 to seal the bottom of the sampling tube 901, and the sling 709 pulls up the sampler 9 to complete the sampling.

[0040] Please refer to Figure 4 and Figure 7 As shown, several groups of slide rods 102 are opened inside the first slide groove 101, several groups of first drainage holes 103 are opened inside the first slide groove 101, multiple groups of second drainage holes 106 are opened inside the second slide groove 104, and four groups of water outlet holes 910 are opened inside the sampler 9, and the water outlet holes 910 pass through the sampler 9 and extend to the interior of the sampling tube 901.

[0041] In this embodiment, the first drainage hole 103 and the second drainage hole 106 are provided to quickly drain the water in the first chute 101 and the second chute 104 to prevent the accumulation of water from affecting the parts of the device. The water outlet 910 can quickly drain the seawater accumulated in the sampling tube 910 when the sampler 9 takes samples into the sampling tube 910.
