Description

Technical Field

[0001] The invention relates to the technical field of marine geological survey, in particular to a multifunctional self-falling seabed physical parameter probe. Background Art

[0002] The submarine sedimentary layer is a general term for submarine sediments formed by various sedimentary processes at the bottom of the ocean. These sediments include rock fragments, organic debris, minerals, etc. They accumulate on the seabed to form a layered structure. Through the propagation and reflection characteristics of sound waves in the submarine sedimentary layer, the thickness of the sedimentary layer can be measured, and its shape and distribution can be depicted. By analyzing the sound wave signal, the physical properties of the sedimentary layer can be inferred. Static sounding of the submarine sedimentary layer can accurately analyze the physical properties of the deep-sea strata, which can provide important original basis for the construction of offshore oil and gas development platforms and oil pipelines.

[0003] For example, the patent publication number is "CN118363069A", and the patent name is "An acoustic static penetration device for seabed sediments", which includes a support assembly, which includes an outer shell, a plurality of counterweights are fixedly connected to the outside of the outer shell, and a plurality of hydraulic cylinders are fixedly connected to the bottom of the outer shell; the measuring assembly includes a first toggle mechanism, two sets of second toggle mechanisms, a probe rod, and an extension mechanism. A first through hole is opened on the outer shell, and the probe rod extends out of the outer shell through the first through hole. The lower end of the probe rod is fixedly connected to an acoustic receiving section and a probe, and a mounting plate is fixedly connected to the inner shell. When the above invention is used, the hydraulic cylinder can be retracted to make the probe rod enter the seabed, and then the probe rod can be moved to continue to extend. The extension mechanism can also be used to adjust the depth of the probe rod entering the seabed sediment layer, which is more convenient to use.

[0004] In the above device, the probe rod is penetrated into the soil through the transmission on the gear, but gears are provided on the half-tube. The existence of the gears makes the penetration and recovery of the probe rod mainly rely on the gear transmission, and the two half-tubes are connected by magnets, and the force is applied by the gears to force the two half-tubes apart. The force applied by the gears may cause structural damage. The penetration and recovery of the probe rod need to be achieved by gears. The teeth on the half-tube are in contact with seawater, and long-term use may easily cause gear wear and transmission failure. Moreover, the connection is only connected by magnets, and the connection is relatively weak. When the probe is penetrated, it is subject to the force and resistance of the gears, which may cause displacement between the two connected half-tubes, thereby affecting the transmission of the tube. For this reason, a multifunctional self-falling seabed physical parameter probe is invented. Summary of the invention

[0046] The power device 8 includes a No. 2 motor 801, which is fixedly installed inside the diving frame 1. The output end of the No. 2 motor 801 is fixedly connected to a threaded rod 802, the outer wall of the threaded rod 802 is threadedly connected to a moving frame 803, and the inside of the moving frame 803 is slidably connected to a clamping assembly 804 for clamping the internal connecting piece 402.

[0047] The control device 2 includes a turntable 201, the outer wall of the turntable 201 is rotatably connected to the inner wall of the diving frame 1, the top of the turntable 201 is rotatably connected to a spiral blade device 202, a No. 4 motor for controlling the rotation of the spiral blade device 202 is installed between the turntable 201 and the spiral blade device 202, and a No. 6 motor for controlling the rotation of the turntable 201 is fixedly connected inside the diving frame 1;

[0048] The interior of the diving frame 1 is fixedly connected with a No. 4 telescopic member 203, the telescopic end of the No. 4 telescopic member 203 is fixedly connected with a wing plate member 204, one side of the wing plate member 204 is fixedly connected with a No. 5 motor 205, the output end of the No. 5 motor 205 is fixedly connected with a guide plate 206, one end of the guide plate 206 is rotatably connected to the interior of the wing plate member 204, the outer wall of the guide plate 206 is movably connected with a contour member 207, and the interior of the diving frame 1 is fixedly connected with a sandwich member 208 for limiting the movement of the contour member 207.

[0049] A limiting device 9 for clamping the round rod 601 is installed inside the diving frame 1. The limiting device 9 includes a No. 6 telescopic member, which is fixedly installed inside the diving frame 1. The telescopic end of the No. 6 telescopic member is fixedly connected to a positioning rod.

[0050] A sonar detector is fixedly connected to the bottom end of the diving frame 1 to detect the seabed during the descent. The position of the diving frame 1 is then controlled by the control device 2. The position of the diving frame 1 is adjusted to prevent the submersible from landing in the reef area. The diving frame 1 is lowered to the seabed sediment layer area through the control device 2. A telescopic support leg device is installed at the bottom end of the diving frame 1. When the sounding instrument is about to fall to the seabed, the telescopic support leg device is started to move the support leg to the outside of the diving frame 1, thereby supporting the sounding instrument at the seabed.

[0051] During the falling process, the output end of the sixth motor rotates, the turntable 201 and the spiral blade device 202 rotate synchronously, the spiral blade device 202 generates power through the rotation of the internal blades, and the position of the submersible frame 1 is controlled by the power. The spiral blade device 202 installed at the top and bottom of the probe is used to control the position of the probe when subjected to the force of the lateral current. The telescopic end of the fourth telescopic member 203 moves, the wing plate member 204 and the guide plate 206 move synchronously. Due to the restriction of the interlayer member 208 on the contour member 207, the guide plate 206 and the contour member 207 slide relative to each other. The extension size of the wing plate member 204 and the guide plate 206 is controlled by the extension of the fourth telescopic member 203. The output end of the fifth motor 205 rotates, and the wing plate member 204 and the guide plate 206 rotate, so as to control the angle of the submersible frame 1 during the falling process, and ensure that the submersible frame 1 can remain perpendicular to the sediment layer area during the falling process. The extension size of the wing plate 204 and the guide plate 206 is retracted to achieve a large extension size at the initial stage of descent to enhance lateral stability, and a small extension size when approaching the sediment layer, thereby improving vertical positioning accuracy. After sinking to the surface of the sediment layer, the wing plate 204 and the guide plate 206 are retracted into the interior of the diving frame 1, and the spiral blades at the bottom are set to be hollow, and the hollow shape allows the probe frame 702 to pass through. During the descent, the probe frame 702 is inside the diving frame 1, so the probe frame 702 will not affect the use of the turntable 201 and the spiral blade device 202. Through the synergistic effect of the spiral blade device 202, the guide plate 206 and the retractable wing plate at the top and bottom of the diving frame 1, the posture of the probe can be dynamically adjusted during the descent to effectively resist the interference of ocean currents. The seabed is detected in combination with sonar, thereby detecting the sediment layer area on the seabed, collecting data through sonar and using it to control the control device 2, ensuring that the probe is positioned and moved to the target sediment layer area, and ensuring the feasibility of the descent.

[0052] The output end of the second motor 801 rotates, and the rotation of the threaded rod 802 allows the movable frame 803 to move along the length of the threaded rod 802. The clamping assembly 804 can clamp the top connecting piece 602. The movable frame 803 and the clamping assembly 804 move synchronously, so that the round rod 601 moves, and the probe device 7 located at the bottom of the round rod 601 penetrates into the seabed sediment layer. After the round rod 601 moves to the bottom, the clamping assembly 804 releases the clamping of the top connecting piece 602, and the output end of the second motor 801 rotates in the opposite direction to facilitate the operation of the closing device 3. The limiting device 9 limits the round rod 601, and the extension of the sixth telescopic member The retracted end moves, the positioning rod and the No. 1 positioning groove on the round rod 601 come into contact, thereby limiting the movement of the round rod 601, and the closing device 3 is started to achieve closing of the cylinder. The telescopic end of the No. 1 telescopic member 301 causes the placement rack 302 to move, and the No. 1 spring shock-absorbing damper 303 applies a force to the half-cylinder assembly 4 stored inside the placement rack 302 through the pressure plate 304. The telescopic end of the No. 3 telescopic member 306 controls the movement of the push rod 307, and the push rod 307 contacts the inner wall of the No. 2 positioning groove 404. The telescopic end of the No. 2 telescopic member 305 moves, and the movement of the half-cylinder assembly 4 is controlled by the push rod 307, thereby achieving closing of the half-cylinder members 401.

[0053] The two semi-cylinder members 401 are connected by a connecting assembly 5, and the spacing between the two semi-cylinder members 401 becomes shorter. The limiting bevels 502 on the two semi-cylinder members 401 contact each other. At this time, the limiting member 504 is subjected to the force of the top rod 307, so that the limiting member 504 and the limiting hole in the limiting bevel 502 are separated. The two limiting bevels 502 contact each other and apply force, and the telescopic end of the No. 2 spring shock-absorbing damper 501 is compressed, so that the limiting bevel 502 moves and the telescopic end of the No. 3 spring shock-absorbing damper 503 contracts. Then the distance between the two semi-cylinder members 401 continues to decrease until it is zero. At this time, due to the shape design of the limiting bevel 502, the telescopic end of the No. 3 spring shock-absorbing damper 503 extends out, and the limiting bevel 502 continuously applies force to the two semi-cylinder members 401, thereby ensuring the stable use of the two semi-cylinder members 401 after connection.

[0054] After the two semi-cylinder members 401 are connected, the two outer connecting members 403 respectively located on the semi-cylinder members 401 contact each other and cooperate with the top connecting member 602. After the cooperation is achieved, the telescopic end of the No. 3 telescopic member 306 causes the top rod 307 to contract, and the top rod 307 and the No. 2 positioning groove 404 are separated. The top rod 307 and the limiting member 504 located inside the semi-cylinder member 401 are separated. The limiting member 504 is affected by the internal elastic force of the No. 3 spring shock-absorbing damper 503, and the limiting member 504 moves to the inside of the limiting hole 505, thereby limiting the limiting bevel block 502. This design can ensure that the limiting bevel block 502 limits the semi-cylinder members 401, and avoids the subsequent separation of the two semi-cylinder members 401. The telescopic end of the telescopic member 305 contracts, the No. 3 telescopic member 306 and the push rod 307 move, and the push rod 307 is moved to the side wall position of the unconnected semi-cylinder member 401. The telescopic end of the No. 3 telescopic member 306 extends, so that the push rod 307 moves to the No. 2 positioning groove 404 on the unconnected semi-cylinder member 401, and contacts with the limiting member 504 on the unconnected semi-cylinder member 401. At this time, the push rod 307 is used to limit the semi-cylinder assembly 4 stored in the placement rack 302. The telescopic end of the No. 1 telescopic member 301 contracts, so that the placement rack 302 and the semi-cylinder assembly 4 on the placement rack 302 move, and the connected semi-cylinder member 401 and the unconnected semi-cylinder member 401 are separated. This distance allows the power device 8 to apply a force to the connected semi-cylinder member 401.

[0055] The output end of the second motor 801 rotates, and at the same time, the clamping assembly 804 clamps the inner connection. After the two inner connections are connected, they have the same shape as the top connection piece 602. Therefore, the clamping assembly 804 can also clamp the top connection piece 602. The output end of the second motor 801 rotates, thereby moving the semi-cylinder piece 401. After the two semi-cylinder pieces 401 are connected, the shape of their cross-sections is the same as the cross-sectional shape of the round rod 601. The semi-cylinder piece 401 moves, so that the round rod 601 and the probe device 7 continue to penetrate into the sediment layer on the seabed, and the closing operation is repeated. Subsequently, the outer connection piece 403 on the semi-cylinder piece 401 is connected to the inner connection piece 402 on the semi-cylinder piece 401.

[0056] A sealing cover that can be controlled by electricity is installed at the bottom of the diving frame 1. When the seabed needs to be inspected, the sealing cover is opened, the telescopic end of the No. 5 telescopic member 11 moves, and the acoustic transmitter 12 moves and contacts the surface of the seabed sediment layer. The acoustic transmitter 12 sends detection sound waves to the ground, and the sensors located inside the sediment layer are concentrated with sensors that receive sound waves. By analyzing the received detection sound waves, the physical properties of the sediment layer can be inferred.

[0057] When it is necessary to detect the inside of the sediment layer through the gravity device, the semi-cylinder is first clamped by the clamping assembly 804, the output end of the No. 1 motor 606 rotates, and the drum 607 reels the connecting rope 605 by rotating. The connecting rope 605 moves as a whole, and the moving distance of the connecting rope 605 can be calculated by the pull-wire encoder. The movement of the connecting rope 605 drives the encoder to rotate, outputs a displacement signal, and calculates the height. The hammer 603 is lifted. After the hammer 603 is lifted to the set height, the No. 1 motor 606 releases the force on the drum 607. Under the gravity of the hammer 603, The hammer 603 is in contact with the top of the probe frame 702, and the hammer 603 applies a force to the probe frame 702. Since the round rod 601 is restricted by the semi-cylinder and the clamping assembly 804, the probe frame 702 will penetrate into the soil under the action of the hammer 603. By detecting the penetration of the probe frame 702 under a single hammering, the sealing of the sediment layer can be effectively understood. During the falling process of the hammer 603, the pulley 604 is in contact with the No. 1 motor 606, so that the pulley 604 rotates. The limit of the pulley 604 ensures the falling of the hammer 603, and since the probe device 7 and the diving frame 1 are installed between There are cables and retractors 10, the cables are used to supply power to the sensors and laser ranging devices inside the probe device 7 and receive data, the hammer 603 is kept hollow inside, and the hollow area is for the cable to pass through, the hammer 603 is restricted by the pulley 604, and the hammer 603 is prevented from affecting the cable. During use, the retractor 10 ensures that the cable is in a vertical state, and the hammer 603 is prevented from being affected by the cable during movement due to the bending of the cable. The hammer 603 moves, and the pulley 604 can move along the first guide rail 608 and the second guide rail 405, through the gravity device and the combination of the hammer The 603 design uses the pulley 604 guide rail system to accurately control the fall of the hammer 603, and uses the hammer energy and laser ranging technology to monitor the displacement of the probe frame 702 in real time, which significantly improves the detection efficiency of the physical parameters of the sedimentary layer and the data accuracy. When detecting the physical parameters of the seabed, static collection can be carried out through the acoustic transmitter 12 and the sensor set on the probe frame 702, and the gravity device applies force on the probe frame 702. According to the movement of the probe frame 702 and the sensors on the probe frame 702, the soil data of the sedimentary layer is collected during the movement, thereby ensuring that the probe can achieve static and dynamic probing.

[0058] The detection device includes a laser ranging device, a laser transmitter is fixedly connected to the inside of the fixed cylinder 701, a reflector is installed on the probe frame 702, and a laser receiver is fixedly connected to the inside of the probe frame 702. The light emitted by the laser transmitter is combined with the reflection of the reflector and is finally received by the laser receiver. The moving distance of the probe frame 702 under a single hammering can be known through the time when the laser transmitter emits the light and the time when the laser receiver receives the light. The probe can emit a detection sound wave to the sediment layer through the acoustic transmitter, and the detection sound wave can be received by the sensor set located inside the sediment layer, thereby realizing static detection, hammering the probe frame 702 through a gravity device, detecting the moving distance of the probe frame 702, and during the movement process, the sensor set located on the probe frame 702 can detect the side wall friction resistance, thereby realizing dynamic detection, and realizing the detection of multiple parameters of the sediment layer through static detection and dynamic detection.

[0059] Hammer 603 preferably adopts a "dead hammer". When the "dead hammer" hits an object, the energy generated by the impact force is absorbed and dispersed by the internal filling material, thereby reducing the vibration effect of the hammer 603. Dead hammers exist in the prior art, and the specific internal structure of the dead hammer is not described here.

[0060] The positioning rod can realize the coordination of the No. 1 positioning groove on the round rod 601 and the No. 2 positioning groove 404 on the semi-cylinder 401, and the telescopic end of the No. 6 telescopic part moves. The positioning rod realizes temporary restriction of the round rod 601 or the semi-cylinder 401 by contacting the No. 1 positioning groove and the No. 2 positioning groove 404 respectively. By temporarily restricting the round rod 601 or the semi-cylinder 401, the closing or separating operation of the closing device 3 is facilitated.

[0061] When the cylinder is separated, the telescopic end of the No. 1 telescopic member 301 is extended and the placement frame 302 moves, so that the semi-cylinder member 401 on the placement frame 302 contacts the semi-cylinder member 401 on the round rod 601. As the placement frame 302 moves, the semi-cylinder member 401 on the round rod 601 is also located inside the placement frame 302 at the same time. Through the movement of the No. 2 telescopic member 305 and the No. 3 telescopic member 306, the contact between the top rod 307 and the semi-cylinder member 401 on the round rod 601 is achieved. Then the telescopic end of the No. 2 telescopic member 305 and the telescopic end of the No. 3 telescopic member 306 are reversely operated to achieve cylinder separation. The telescopic end of the No. 1 telescopic member 301 is contracted, and the placement frame 302 moves in the opposite direction, so that the power device 8 lifts the round rod 601 and the semi-cylinder at the lower position for subsequent cylinder separation operations. The No. 1 spring shock-absorbing damper 303 is always in a compressed state, thereby ensuring that a force is applied to the semi-cylinder when the cylinder is closed.

[0062] When the cylinder is separated, the push rod 307 contacts the No. 2 positioning groove 404 and the limiting member 504 on the semi-cylinder member 401 respectively, the telescopic end of the No. 3 telescopic member 306 moves, and the push rod 307 applies a force to the limiting member 504, so that the limiting member 504 and the limiting inclined block 502 separate. At this time, the limiting inclined block 502 can realize the movement when separating, and the telescopic end of the No. 2 telescopic member 305 contracts, so that the two connected semi-cylinder members 401 separate. During the separation process, the No. 2 telescopic member 305 limits the semi-cylinder assembly 4 inside the semi-cylinder assembly 4. After the cylinder is separated, the probe can be recovered. The telescopic parts cooperate with the spring shock-absorbing damper to realize the rapid merging and separation of the semi-cylinder parts 401. This design does not require gear transmission. The thrust assembly then applies force to the semi-cylinder to achieve the penetration and recovery of the probe. This transmission method is stable, simplifies the structure and reduces wear. The two semi-cylinder parts 401 are merged through the connecting assembly 5. When the two semi-cylinder parts 401 are merged, the second spring shock-absorbing damper 501 and the limiting bevel 502 make the two semi-cylinder parts 401 still exert force on each other when in contact, thereby achieving close contact between the two semi-cylinder parts 401, thereby ensuring the stability of use and the transmission effect after the merging.
