Description

Technical Field

[0001] This invention relates to the field of geological exploration technology, and in particular to a geological exploration device and its control method based on GPS positioning services. Background Technology

[0002] With the continuous development of modern technology, marine exploration technology is also constantly evolving. For example, acoustic exploration, electromagnetic exploration, and seismic exploration have become the main means of marine exploration. At the same time, submersibles, drones, and remote sensing technology have also provided support for exploration work, providing information support for us to better understand the ocean and better protect and explore marine resources.

[0003] Existing technologies disclose some invention patents related to marine geological exploration. Chinese invention patent application number 202310982713.1 discloses a marine geological exploration data analysis sample acquisition device, which includes a base fixedly installed on a marine drilling platform for the drill pipe to pass through. The base is provided with a cleaning mechanism, which includes a brush plate assembly. The cleaning surface of the brush plate assembly contacts the drill pipe.

[0004] When sampling deep-sea seabed soil, a box sampler is usually lowered to the seabed, and the weight of the hammer causes the sampling tube to insert into the seabed soil. The closed shovel rotates and cuts the bottom soil into the sampling tube. Due to the influence of ocean currents, the box sampler will swing, making it difficult to maintain a vertical position. If the box sampler sinks to the seabed at an angle, it may tip over after colliding with the seabed, thus affecting normal sampling. At the same time, as the box sampler moves upward, the swing of the box sampler will cause disturbance to the sample inside, resulting in inaccurate geological exploration results. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the swaying of box samplers due to ocean currents, which makes it difficult to maintain a vertical position; the potential for the box sampler to tip over upon collision with the seabed when it sinks at an angle, thus affecting normal sampling; and the swaying of the box sampler during its upward movement causing disturbance to the samples inside, leading to inaccurate geological exploration results. Therefore, this invention proposes a geological exploration device and its control method based on GPS positioning services.

[0006] In a first aspect, the present invention provides a geological exploration device based on GPS positioning services, including a housing, and further comprising:

[0007] An air chamber, located inside the housing, is used to store high-pressure gas;

[0008] An airbag, installed on the outer wall of the box, is used to increase the buoyancy of the top of the box during the upward movement of the box.

[0009] A counterweight is fixedly installed inside the box to keep the box in a vertical position.

[0010] A sampling mechanism, installed inside the container, is used to take samples after the container is inserted into the seabed;

[0011] A power unit, installed inside the housing, is used to push the sampling mechanism into the seabed soil;

[0012] A support mechanism is slidably sleeved on the outside of the container body to support the container body after it falls to the seabed;

[0013] During the descent of the container, a counterweight keeps it vertical. The air chamber uses high-pressure gas to assist the counterweight in maintaining verticality. Once the container reaches the seabed, the power unit ejects the high-pressure gas from the top of the container, applying a downward reaction force. This force is then used by a sampling mechanism to collect samples. After sampling, the sampling mechanism rests against the bottom of the counterweight, which supports the mechanism.

[0014] In further implementation, the power assembly includes:

[0015] A cavity is formed inside the housing, and a connecting hole is formed on the side wall of the cavity, the bottom end of which communicates with the air cavity;

[0016] The first solenoid valve is fixedly installed inside the communicating hole;

[0017] Multiple vents are provided on the top of the housing, and all of the vents are connected to the cavity. Each of the vents is equipped with a one-way valve.

[0018] A pressure sensor is installed inside the air chamber to detect the air pressure inside the air chamber;

[0019] After the container sinks to the seabed, the first solenoid valve opens, releasing the high-pressure gas in the air chamber. The gas is discharged from multiple exhaust ports. As the high-pressure gas is discharged from the exhaust ports, it generates a strong reaction force, which exerts a downward force on the container, causing the sampling mechanism to move downward and insert into the seabed soil. After the pressure sensor detects that the air pressure inside the air chamber has dropped to the set value, the first solenoid valve closes to stop the exhaust.

[0020] In further implementation, the sampling mechanism includes:

[0021] Two mounting slots are symmetrically provided on the inner wall of the housing;

[0022] Two sliding plates are respectively slidably and sealingly connected inside the two mounting slots;

[0023] Two rotating rods are respectively rotatably connected to the two sliding plates, and a disc is fixed on the outer ring of each of the two rotating rods;

[0024] Two hoppers are rotatably connected to the two rotating rods respectively, and the two hoppers are respectively connected to the corresponding discs by bolts;

[0025] A drive assembly for driving the two rotating rods to rotate in opposite directions;

[0026] A lifting assembly is used to drive the two sliding plates to move upward synchronously.

[0027] After the sampling mechanism is inserted into the seabed soil, the drive component drives the two hoppers to rotate and scoop up the seabed soil. Then the lifting component drives the two hoppers to move upward and abut against the bottom of the counterweight block so that the two hoppers fit tightly together.

[0028] In further implementation, the driving component includes:

[0029] Two first electric telescopic rods are fixedly connected to the two sliding plates respectively, and the first electric telescopic rods are located on one side of the sliding plates. The telescopic ends of the two first electric telescopic rods are fixed with racks.

[0030] Two gears are respectively fixed to the outer periphery of the two rotating rods, and the gears in the same mounting groove mesh with the rack.

[0031] The two racks mesh with the opposite sides of the two gears respectively. After the two first electric telescopic rods are started, the two rotating rods rotate in opposite directions, and the two rotating rods drive the two hoppers to scoop up the soil from the seabed.

[0032] In further implementation, the lifting assembly includes:

[0033] The second electric telescopic rod is fixedly installed on the inner wall of the box;

[0034] A crossbar is fixedly installed at the telescopic end of the second electric telescopic rod, and the bottom of the crossbar is fixedly connected to the top of the two sliding plates;

[0035] After the second electric telescopic rod retracts, it drives the crossbar to rise, so that the two hoppers rise synchronously. The tops of the two hoppers rise to abut against the bottom of the counterweight, and the counterweight supports the hoppers.

[0036] In further implementation, the supporting mechanism includes:

[0037] A fixing plate is fixed to the outer wall of the box. Multiple sleeves are installed at the bottom of the fixing plate. A sliding frame is fixed to the bottom of the multiple sleeves. The sliding frame is slidably connected to the outer wall of the box.

[0038] Four connecting rods are respectively fixedly installed on the side wall of the sliding frame, and a ring is fixedly fixed to the bottom of the four connecting rods. A flexible pad is fixedly installed at the bottom of the ring.

[0039] After the container sinks to the seabed, it first contacts the seabed through a ring to reduce the impact on the container. Then, under the action of gravity, the ring changes from an inclined state to a state that is in contact with the seabed, and drives the container to move and adjust the container to a vertical state.

[0040] Further implementation will also include:

[0041] The flow channel is formed in the inner wall of the box body. The flow channel is fixedly connected to the inside of the airbag through a connecting pipe. An exhaust valve is installed inside the connecting pipe.

[0042] Multiple exhaust ports are provided on the inner wall of the housing, and all of the exhaust ports are connected to the flow channel;

[0043] After sampling is completed, the soil sample in the hopper is poured out, and the gas in the airbag is released through the exhaust port. The gas in the airbag is used to blow off the soil adhering to the counterweight.

[0044] Secondly, a control method for a geological exploration device based on GPS positioning services is provided, which also includes:

[0045] The controller is installed inside the enclosure;

[0046] A GPS locator is installed inside the enclosure to locate the position of the enclosure.

[0047] The control method includes the following steps:

[0048] The controller receives location information sent by the GPS locator;

[0049] The controller generates first control information based on the location information;

[0050] The controller sends first control information to the first solenoid valve to control the first solenoid valve to open;

[0051] The controller receives air pressure information sent by the air pressure sensor;

[0052] The controller generates second control information based on the air pressure information;

[0053] The controller sends second control information to the first solenoid valve to control the first solenoid valve to close.

[0054] In further implementation, the specific working method of the driving component during the sampling process is as follows:

[0055] The controller receives air pressure information sent by the air pressure sensor;

[0056] The controller generates third control information based on the air pressure information, and the third control information is used to control the movement of the first electric telescopic rod.

[0057] The controller sends third control information to the first electric telescopic pole to control the first electric telescopic pole to retract a specified distance.

[0058] In further implementation, the specific working method of the lifting component during the lifting process is as follows:

[0059] The controller receives retraction completion information from the first electric telescopic rod;

[0060] The controller generates fourth control information based on the retraction distance information, and the fourth control information is used to control the movement of the second electric telescopic pole.

[0061] The controller sends fourth control information to the second electric telescopic pole to control the second electric telescopic pole to retract a specified distance.

[0062] Compared with the prior art, the present invention has the following beneficial effects:

[0063] 1. This invention, through the configuration of the power component, after the container sinks to the seabed and is positioned, releases the high-pressure gas inside the air chamber from the top of the container. On one hand, the reaction force generated when releasing the high-pressure gas acts on the container, giving it a downward force. Combined with the gravity of the counterweight, this facilitates the insertion of the sampling mechanism inside the container into the deep seabed soil. On the other hand, after the high-pressure gas in the air chamber is released, the mass of the top of the container becomes lighter, and the sampling mechanism takes seabed soil from the bottom of the container, increasing the weight of the bottom of the container. The lighter top and heavier bottom of the container lowers the center of gravity of the container. During the ascent of the container, this helps to keep the container stable in a vertical position, thereby reducing disturbance to the sample.

[0064] 2. By setting up a support mechanism, if the container tilts due to the ocean currents, the support mechanism will first contact the seabed. On the one hand, the support mechanism can reduce the impact when the container sinks to the seabed, and on the other hand, the support mechanism can adjust the position of the tilted container so that the container returns to a vertical state before contacting the seabed.

[0065] 3. By incorporating an airbag, the unreleased gas inside the air chamber enters the airbag during the ascent of the housing. The airbag expands from a deflated state, and the buoyancy generated by the airbag reduces the tension on the cable, preventing cable breakage. Furthermore, the buoyancy of the airbag provides an upward buoyancy to the top of the housing, which, in conjunction with the downward gravity generated by the counterweight, keeps the housing stable in a vertical position.

[0079] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0080] like Figures 2 to 10 The illustrated geological exploration equipment based on GPS positioning services includes a housing 1, and further includes:

[0081] Gas chamber 2, located inside housing 1, is used to store high-pressure gas;

[0082] Airbag 3 is installed on the outer wall of box 1 to increase the buoyancy of the top of box 1 during the ascent of box 1;

[0083] Counterweight 4 is fixedly installed inside the box 1 to keep the box 1 in a vertical position;

[0084] The sampling mechanism is installed inside the container 1 and is used to take samples after the container 1 is inserted into the seabed;

[0085] The power unit, installed inside the housing 1, is used to push the sampling mechanism into the seabed soil;

[0086] The support mechanism is slidably sleeved on the outside of the container 1 and is used to support the container 1 after it falls to the seabed.

[0087] During the descent of container 1, counterweight 4 keeps container 1 vertical. During the descent of container 1, air chamber 2 uses high-pressure gas inside to assist counterweight 4 in keeping container 1 vertical. After container 1 sinks to the seabed, the power unit sprays high-pressure gas from the top of container 1 from air chamber 2, applying a downward reaction force to container 1. Sampling is carried out by the sampling mechanism. After sampling is completed, the sampling mechanism is placed against the bottom of counterweight 4, and the counterweight 4 supports the sampling mechanism.

[0088] During the ascent of the box 1, the high-pressure gas in the air chamber 2 enters the air bladder 3. The expansion of the air bladder 3 increases the buoyancy of the top of the box 1. This, combined with the gravity of the counterweight 4, lowers the center of gravity of the box 1, ensuring that the box 1 remains in a vertical position.

[0089] In the specific implementation process, a circular hole 33 is opened through the side wall of the box 1, and the airbag 3 and the air chamber 2 are connected through the circular hole 33. A second solenoid valve 34 is installed inside the circular hole 33.

[0090] The top of the box 1 is fixed with a hook 35, and the inside of the box 1 is equipped with a storage battery 36.

[0091] Specifically, due to the influence of ocean currents, the box sampler will sway, making it difficult to maintain a vertical position. If the box sampler sinks to the seabed at an angle, it may tip over after colliding with the seabed, thus affecting normal sampling. Furthermore, during the upward movement of the box sampler, its swaying will disturb the samples inside, leading to inaccurate geological exploration results. This embodiment of the invention can solve the above problems. The specific implementation method is as follows: First, the worker attaches the cable to the hook 35, and then uses a crane to lift the box sampler. Body 1 is lifted off the hull and placed on the seabed. During the sinking of body 1, the weight of the bottom of body 1 is increased by the setting of counterweight 4, which helps to keep body 1 in a vertical position during the sinking process. After body 1 sinks to the seabed, if body 1 tilts due to the seabed current, the set support mechanism will contact the seabed first. On the one hand, the support mechanism can reduce the impact generated when body 1 sinks to the seabed. On the other hand, the support mechanism can adjust the position of body 1 that has tilted, so that body 1 returns to a vertical position and then contacts the seabed.

[0092] After the container 1 sinks to the seabed and is positioned, the power unit releases the high-pressure gas inside the air chamber 2 from the top of the container 1. On the one hand, the reaction force generated when the high-pressure gas is released acts on the container 1, giving it a downward force. Combined with the weight of the counterweight 4, this helps the sampling mechanism in the container 1 to penetrate deep into the seabed soil. On the other hand, after the high-pressure gas in the air chamber 2 is released, the mass of the top of the container 1 becomes lighter. The sampling mechanism takes seabed soil from the bottom of the container 1, increasing the weight of the bottom of the container 1. The lighter top and heavier bottom of the container 1 lowers the center of gravity of the container 1. During the ascent of the container 1, this helps the container 1 to remain stable in a vertical position, thereby reducing disturbance to the sample.

[0093] After sampling is completed, the sampling mechanism moves towards the inside of the box 1 and presses against the bottom of the counterweight 4, which helps to prevent the sample from spilling. During the process of the box 1 rising, the gas that has not been released in the air chamber 2 enters the airbag 3. The airbag 3 expands from a deflated state. The buoyancy generated by the airbag 3 can reduce the tension on the cable and prevent the cable from breaking. On the other hand, the buoyancy of the airbag 3 makes the top of the box 1 receive a vertical upward buoyancy, which works in conjunction with the vertical downward gravity generated by the counterweight 4 to keep the box 1 stable in a vertical state.

[0094] After the material in the chamber 1 is discharged, the staff releases the gas inside the airbag 3 and blows the gas inside the airbag 3 along the channel inside the chamber 1 to the bottom of the counterweight 4, so that the sample adhering to the bottom of the counterweight 4 is blown off.

[0095] In further implementation, the power components include:

[0096] Cavity 5 is located inside the housing 1. A connecting hole 6 is provided on the side wall of cavity 5, and the bottom end of the connecting hole 6 is connected to air cavity 2.

[0097] The first solenoid valve 7 is fixedly installed inside the connecting hole 6;

[0098] Multiple vent holes 8 are located on the top of the housing 1. All multiple vent holes 8 are connected to the cavity 5. A one-way valve 9 is installed inside each of the multiple vent holes 8.

[0099] The air pressure sensor 10 is installed inside the air chamber 2 and is used to detect the air pressure inside the air chamber 2.

[0100] After the container 1 sinks to the seabed, the first solenoid valve 7 opens to release the high-pressure gas in the air chamber 2 and discharges it from multiple exhaust ports 8. The high-pressure gas generates a strong reaction force during the discharge from the exhaust ports 8, which exerts a downward force on the container 1, causing the sampling mechanism to move downward and insert into the seabed soil. After the pressure sensor 10 detects that the pressure value inside the air chamber 2 has dropped to the set value, the first solenoid valve 7 is closed to stop the exhaust.

[0101] Specifically, after the container 1 sinks to the seabed and the support mechanism adjusts the container 1, the first solenoid valve 7 opens. The high-pressure gas inside the air chamber 2 enters the cavity 5 through the connecting hole 6, and then enters multiple exhaust holes 8 from the cavity 5. Subsequently, it is discharged from the exhaust holes 8. The discharge of high-pressure gas will generate a large reaction force. The reaction force of the high-pressure gas discharge will cause the container 1 to move downward, which will help the bottom of the container 1 to insert into the depth of the seabed soil. The multiple exhaust holes 8 are provided to ensure that the force generated by the exhaust is evenly applied to the container 1, preventing the container 1 from tilting or loosening due to uneven force.

[0102] In the further implementation process, the sampling institutions include:

[0103] Two mounting slots 11 are symmetrically opened on the inner wall of the housing 1;

[0104] Two sliding plates 12 are respectively slidably and sealingly connected inside the two mounting grooves 11;

[0105] Two rotating rods 13 are respectively rotatably connected to two sliding plates 12, and a disc 14 is fixed on the outer ring of each of the two rotating rods 13.

[0106] Two hoppers 15 are rotatably connected to two rotating rods 13 respectively, and the two hoppers 15 are respectively connected to the corresponding discs 14 by bolts;

[0107] A drive assembly is used to drive the two rotating rods 13 to rotate in opposite directions;

[0108] The lifting assembly is used to drive the two sliding plates 12 to move upward synchronously.

[0109] After the sampling mechanism is inserted into the seabed soil, the drive component drives the two hoppers 15 to rotate and scoop up the seabed soil. Then the lifting component drives the two hoppers 15 to move upward and abut against the bottom of the counterweight 4 so that the two hoppers 15 fit tightly together.

[0110] Specifically, during the sampling of seabed soil, the drive assembly drives two rotating rods 13 to rotate in opposite directions. Each of the two rotating rods 13 drives a hopper 15 bolted to it via a disc 14, causing the two hoppers 15 to rotate in opposite directions. The rotation of the two hoppers 15 scoops up the seabed soil, and the two hoppers 15 abut against each other after scooping up the seabed soil to prevent external water from entering and samples from leaking out. After sampling is completed, the lifting assembly starts, causing two sliding plates 12 to move upward synchronously. The two sliding plates 12 drive the corresponding rotating rods 13 to move upward, and the rotating rods 13 drive the hoppers 15 to move upward, so that the two hoppers 15 enter the interior of the box 1. Then, the tops of the two hoppers 15 abut against the bottom of the counterweight 4. By abutting against the bottom of the counterweight 4, the contact between the two hoppers 15 is strengthened, which is beneficial to prevent gaps from appearing at the contact point between the two hoppers 15 during the ascent of the box 1.

[0111] In further implementation, the driving components include:

[0112] Two first electric telescopic rods 16 are fixedly connected to two sliding plates 12 respectively, and the first electric telescopic rods 16 are located on one side of the sliding plate 12. The telescopic ends of the two first electric telescopic rods 16 are fixed with racks 17.

[0113] Two gears 18 are fixed to the outer periphery of two rotating rods 13 respectively, and the gears 18 in the same mounting groove 11 mesh with the rack 17;

[0114] The two racks 17 mesh with the opposite sides of the two gears 18 respectively. After the two first electric telescopic rods 16 are started, the two rotating rods 13 rotate in opposite directions. The two rotating rods 13 drive the two hoppers 15 to scoop up the soil on the seabed.

[0115] Specifically, after the sampling mechanism is inserted into the seabed soil, the two first electric telescopic rods 16 are started synchronously. The two first electric telescopic rods 16 drive the corresponding racks 17 to move upward. The movement of the racks 17 drives the gears 18 meshing with them to rotate. The two gears 18 drive the rotating rods 13 fixedly connected to them to rotate. The two rotating rods 13 drive the discs 14 to rotate. The two discs 14 drive the corresponding hoppers 15 to rotate. The two hoppers 15 rotate in opposite directions, thereby scooping up and sampling the seabed soil.

[0116] In further implementation, the lifting assembly includes:

[0117] The second electric telescopic rod 19 is fixedly installed on the inner wall of the box 1;

[0118] The crossbar 20 is fixedly installed at the telescopic end of the second electric telescopic rod 19, and the bottom of the crossbar 20 is fixedly connected to the top of the two sliding plates 12.

[0119] After the second electric telescopic rod 19 retracts, it drives the crossbar 20 to rise, so that the two hoppers 15 rise synchronously. The tops of the two hoppers 15 rise to abut the bottom of the counterweight 4, and the counterweight 4 supports the hoppers 15.

[0120] Specifically, after the two hoppers 15 complete the sampling of the seabed soil, the second electric telescopic rod 19 is activated, which drives the crossbar 20 to move upward. The crossbar 20 drives the two sliding plates 12 fixedly connected to it to move upward synchronously. The two sliding plates 12 drive the corresponding rotating rods 13 to move upward respectively. The rotating rods 13 drive the hoppers 15 to move upward. The two hoppers 15 move upward until the top of the hoppers 15 abuts against the bottom of the counterweight block 4. The rigid force of the second electric telescopic rod 19 drives the hoppers 15 to abut against the counterweight block 4, which helps to prevent gaps from appearing at the contact point of the two hoppers 15 due to the weight of the sample.

[0121] In the further implementation process, the supporting institutions include:

[0122] A fixing plate 21 is fixed to the outer wall of the housing 1. Multiple sleeves 22 are installed at the bottom of the fixing plate 21. A sliding frame 23 is fixed at the bottom of the multiple sleeves 22. The sliding frame 23 is slidably connected to the outer wall of the housing 1.

[0123] Four connecting rods 24 are fixedly installed on the side wall of the sliding frame 23 respectively. A ring 25 is fixedly fixed to the bottom of the four connecting rods 24. A flexible pad 26 is fixedly installed at the bottom of the ring 25.

[0124] After the container 1 sinks to the seabed, the ring 25 first contacts the seabed to reduce the impact on the container 1. Then, under the action of gravity, the ring 25 changes from an inclined state to a state of being in contact with the seabed, and drives the container 1 to move and adjust the container 1 to a vertical state.

[0125] Specifically, during the descent of the container 1, because the top of the container 1 is pulled by a cable, the descent speed of the container 1 is lower than the free descent speed of the ring 25. As a result, the ring 25 pulls the sliding frame 23 downward, and the sliding frame 23 pulls the sleeve 22 to extend. After the container 1 sinks to the seabed, if the container 1 is tilted due to the impact of the seabed current, the ring 25 will first contact the seabed in a point support manner. After contact, under the action of gravity, the lower surface of the ring 25 contacts the seabed, thereby driving the sliding frame 23 to move and adjust the state of the container 1, so that the container 1 is in a vertical state, which is conducive to the container 1 being inserted into the seabed soil for sampling. At the same time, the descent speed of the container 1 is relatively fast, and the ring 25 will generate an impact when it contacts the seabed. By installing a flexible pad 26 at the bottom of the ring 25, the vibration can be reduced when the ring 25 contacts the seabed, protecting the internal instruments of the container 1.

[0126] Further implementation will also include:

[0127] The flow channel 27 is opened in the inner wall of the box 1. The flow channel 27 is fixedly connected to the inside of the airbag 3 through the connecting pipe 28. An exhaust valve 29 is installed inside the connecting pipe 28.

[0128] Multiple exhaust ports 30 are provided on the inner wall of the housing 1, and all of the multiple exhaust ports 30 are connected to the flow channel 27;

[0129] After sampling is completed, the soil sample in the hopper 15 is poured out, and the gas in the air bag 3 is released through the exhaust port 30. The gas in the air bag 3 is used to blow off the soil adhering to the counterweight 4.

[0130] Specifically, when the two hoppers 15 are in contact with the bottom of the counterweight 4, the sample inside the hopper 15 will adhere to the bottom of the counterweight 4.

[0131] After the staff removes the sample from the bottom of the box 1, they open the exhaust valve 29. The high-pressure gas in the airbag 3 enters the flow channel 27 through the connecting pipe 28, and then sprays out from the flow channel 27 along multiple exhaust ports 30. The exhaust ports 30 are directly facing the bottom of the counterweight 4. The high-pressure gas impacts the top of the counterweight 4, which helps to blow off the sample adhering to the bottom of the counterweight 4.

[0132] like Figure 1 The control method for a geological exploration device based on GPS positioning services, as shown, further includes:

[0133] Controller 31 is installed inside housing 1;

[0134] GPS locator 32 is installed inside the housing 1 and is used to locate the position of the housing 1;

[0135] The control method includes the following steps:

[0142] The GPS locator 32 receives radio signals from GPS satellites to locate the position of the container 1. During the descent of the container 1, the GPS locator 32 sends the location information to the controller 31. After the GPS location of the container 1 remains unchanged for a period of time, the controller 31 generates first control information based on the location information. Subsequently, the controller 31 sends the first control information to the first solenoid valve 7 to control the opening of the first solenoid valve 7 so that the high-pressure gas inside the air chamber 2 is ejected. After the high-pressure gas is ejected, the air pressure inside the air chamber 2 continues to decrease. After the air pressure sensor 10 detects that the air pressure inside the air chamber 2 has decreased to a set value, the air pressure sensor 10 sends the air pressure information to the controller 31.

[0146] The controller 31 sends the third control information to the first electric telescopic pole 16 to control the first electric telescopic pole 16 to retract a specified distance;

[0147] When the air pressure sensor 10 detects that the air pressure inside the air chamber 2 has dropped to a set value, the air pressure sensor 10 sends the air pressure information to the controller 31. The controller 31 generates third control information based on the air pressure information, and then sends the third control information to the first electric telescopic rod 16 to control the first electric telescopic rod 16 to retract and drive the rack 17 to move.

[0151] The controller 31 sends the fourth control information to the second electric telescopic pole 19 to control the second electric telescopic pole 19 to retract a specified distance;

[0152] Specifically, after the first electric telescopic rod 16 retracts to a specified distance, the first electric telescopic rod 16 generates retraction completion information and feeds it back to the controller 31. The controller 31 generates fourth control information based on the retraction completion information fed back by the first electric telescopic rod 16. The controller 31 sends the fourth control information to the second electric telescopic rod 19 to control the second electric telescopic rod 19 to retract, thereby driving the hopper 15 to move into the interior of the box 1.

[0153] Working principle of this invention:

[0154] Due to the influence of ocean currents, the box sampler will sway, making it difficult to maintain a vertical position. If the box sampler sinks to the seabed at an angle, it may tip over after colliding with the seabed, affecting normal sampling. Furthermore, during the upward movement of the box sampler, its swaying will disturb the samples inside, leading to inaccurate geological exploration results. This embodiment of the invention solves the above problems. The specific implementation method is as follows: First, the worker attaches the cable to the hook 35, and then uses a crane to lift the box body 1. The container 1 is lifted off the hull and placed on the seabed. During the sinking process, the counterweight 4 increases the weight at the bottom of the container 1, which helps to keep the container 1 in a vertical position. If the container 1 tilts due to the current after sinking to the seabed, the support mechanism will contact the seabed first. On the one hand, the support mechanism can reduce the impact when the container 1 sinks to the seabed, and on the other hand, the support mechanism can adjust the position of the tilted container 1 so that the container 1 returns to a vertical position before contacting the seabed.

[0155] After the container 1 sinks to the seabed and is positioned, the power unit releases the high-pressure gas inside the air chamber 2 from the top of the container 1. On the one hand, the reaction force generated when the high-pressure gas is released acts on the container 1, giving it a downward force. Combined with the weight of the counterweight 4, this helps the sampling mechanism in the container 1 to penetrate deep into the seabed soil. On the other hand, after the high-pressure gas in the air chamber 2 is released, the mass of the top of the container 1 becomes lighter. The sampling mechanism takes seabed soil from the bottom of the container 1, increasing the weight of the bottom of the container 1. The lighter top and heavier bottom of the container 1 lowers the center of gravity of the container 1. During the ascent of the container 1, this helps the container 1 to remain stable in a vertical position, thereby reducing disturbance to the sample.

[0156] After sampling is completed, the sampling mechanism moves towards the inside of the box 1 and presses against the bottom of the counterweight 4, which helps to prevent the sample from spilling. During the process of the box 1 rising, the gas that has not been released in the air chamber 2 enters the airbag 3. The airbag 3 expands from a deflated state. The buoyancy generated by the airbag 3 can reduce the tension on the cable and prevent the cable from breaking. On the other hand, the buoyancy of the airbag 3 makes the top of the box 1 receive a vertical upward buoyancy, which works in conjunction with the vertical downward gravity generated by the counterweight 4 to keep the box 1 stable in a vertical state.

[0157] After the material in the chamber 1 is discharged, the staff releases the gas inside the airbag 3 and blows the gas inside the airbag 3 along the channel inside the chamber 1 to the bottom of the counterweight 4, so that the sample adhering to the bottom of the counterweight 4 is blown off.

[0158] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
