Description

Technical Field

[0001] This invention belongs to the field of geological exploration, specifically a stratigraphic profiler. Background Technology

[0002] A shallow seismic profiler (SPR) is a device that uses the propagation and reflection of sound waves in water and underwater sediments to probe the seabed strata. It was developed based on echo sounding technology. The SPR uses sound wave reflection to create a continuous profile during transect surveys, providing clear information on seabed strata with significant differences. In marine engineering and marine geological exploration, it can provide information on overburden thickness, bedrock depth, and the distribution of fault structures; identify the distribution of seabed obstacles; and understand marine hazard conditions, thus providing technical support for various engineering projects.

[0003] Existing technologies, such as CN106768043B, draw on the application experience of shallow seismic profilers in various engineering projects, introducing shallow seismic profilers for harbor basin exploration before steel pipe pile driving in wharf engineering, providing a rapid technical measure for pile driving construction. However, the above-mentioned devices can only perform measurements through a towed, mobile working method, and cannot be equipped with floating components to achieve free exploration. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to provide a geological exploration-based profile measurement device with a floating component, enabling free exploration.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A stratigraphic profiler includes a hanging ring and a protective cage connected to each other. The protective cage includes an integrally manufactured suspension layer, a flexible layer and an output layer from top to bottom. Several side supports are bonded to the outside of the flexible layer. The cross-section of any side support is rectangular, and the side supports form a circular matrix along the flexible layer. When the flexible layer is in a natural state, the side supports are in a contracted state.

[0006] The suspension layer has a clockwise threaded groove inside, and the output layer has a counterclockwise threaded groove inside. A bolt is threaded between the clockwise and counterclockwise threaded grooves, and an ejector motor is provided at the tail of the bolt.

[0007] The above solution achieves the following beneficial effects: 1. When using this technical solution, the characteristics of sonar propagation and reflection within underwater sediments by the protective cage can be used to detect the underwater strata and form a profile map of the underwater strata.

[0008] 2. When the exploration is completed, this technical solution can adopt two modes. One is the towing mode, which uses the onboard measuring equipment of the exploration vessel to explore a local area. The other is to drop the device into a specific area for free exploration (such as a Lagrange circulation detector). In the process of free exploration, it is necessary to solve the problem of the device's floating and sinking depth in order to realize the problem of detecting strata at different depths. Therefore, during use, the ejector motor can be used to drive the bolt to rotate. At this time, the bolt will pass through the clockwise thread groove and the counterclockwise thread groove during the downward rotation.

[0009] With different spiral directions of the threaded grooves, the suspension layer and the output layer come together (squeezing towards the flexible layer in the middle). The flexible layer that is squeezed becomes flat, thereby increasing the width of the flexible layer. The increased width of the flexible layer will increase the buoyancy of the device, thereby causing the device to float. This changes the degree of floating of the device and achieves a change in position.

[0010] 3. Compared with existing technologies that rely on floating and changing, this technical solution utilizes the side support bonded to the flexible layer to achieve expansion and contraction. When the flexible layer is in its natural state, the side support is in a contracted state, at which point the volume of the device is at its minimum, and therefore the buoyancy force on the device is also at its minimum. However, when the bolt rotates downwards, the flexible layer is compressed, and at this time the side support diverges and expands, thus the side support acts as a buoyancy device, causing the device to float.

[0011] Furthermore, the outer surface of the suspension layer has a storage box with a through hole. One end of the side support passes through the storage box along the through hole, and the other end of the side support is bonded to the outer surface of the output layer. The through hole of the storage box contains a trapezoidal block with the bottom of the trapezoid close to the hanging ring, and the thickness of the trapezoid gradually increases from the bottom to the top.

[0012] Beneficial effects: 1. In this technical solution, the storage box is used to limit the extension direction and extension of the side support. When the flexible layer shrinks, the side support moves downward along the storage box. At this time, the junction of the side support and the trapezoidal block serves as the fulcrum. When the width of the flexible layer widens and expands the side support, the side support spreads out along the fulcrum in a direction away from the device.

[0013] 2. When the flexible layer returns to its original position, the side support moves upward along the storage box. At this time, the storage box limits the return direction of the side support to prevent the water flow from disturbing the side support.

[0014] Furthermore, the suspension layer has a first horizontal placement frame, the output layer has a second horizontal placement frame, the second placement frame is fixedly connected to a sonar, and the ejector motor is fixed to the first placement frame.

[0015] Beneficial effect: A stable effect is achieved by using the first and second placement racks.

[0016] Furthermore, the suspension layer has a built-in power module, a signal transmission module, and a signal processing module. The signal processing module is used to process the signals received and fed back by the sonar, and the signal transmission module is used to transmit the information generated by the signal processing module.

[0017] Furthermore, the sonar is connected to a beam stabilization system, which includes a transducer array, a velocity sensor, and a pitch sensor. The transducer array and the velocity sensor combine to form the sonar transmission aperture, and the pitch sensor is used to measure the current direction of motion.

[0018] Preferably, the transducer array includes a transmitting array and a receiving array.

[0019] Furthermore, the ejector motor is equipped with an activation button, which is used to drive the ejector motor to run according to the signal sent by the signal transmission module.

[0020] Beneficial effects: In practical operation, the circuit components of this device operate using a towed, mobile method. Under the operator's control, the sonar transmits acoustic signals from the transducer array (transmitting array). After reflection off the seabed, the signals are received by the transducer array (receiving array), where they undergo filtering, amplification, and other preprocessing. Finally, the signal processing module records points at different depths corresponding to different times. At the end of the mobile operation, these points are connected to form lines reflecting the seabed and stratigraphic interfaces. From this intuitive and continuous underwater stratigraphic profile, layering and grayscale identification allow for geological analysis.

[0021] Furthermore, the sonar passes through the output layer, and the overlap between the sonar and the output layer is sealed with a gasket.

[0022] Beneficial effect: Waterproofing treatment. Attached Figure Description

[0026] The following detailed description illustrates the specific implementation method:

[0027] The reference numerals in the accompanying drawings include: 1. Lifting ring; 2. Protective cage; 3. Suspension layer; 4. Flexible layer; 5. Output layer; 6. First placement frame; 7. Second placement frame; 8. Sonar; 9. Sealing gasket; 10. Side support; 11. Clockwise threaded groove; 12. Counterclockwise threaded groove; 13. Bolt; 14. Ejector motor; 15. Storage box; 16. Trapezoidal block; 17. Power module; 18. Signal transmission module; 19. Signal processing module; 20. Transducer array; 21. Speed ​​sensor; 22. Pitch and roll sensor.

[0028] The basic implementation examples are as follows: Figure 1 and Figure 2 As shown: A stratigraphic profiler includes a lifting ring 1 and a protective cage 2 connected to each other. The protective cage 2 includes, from top to bottom, an integrally manufactured suspension layer 3, a flexible layer 4, and an output layer 5. The suspension layer 3 has a first horizontal placement frame 6, and the output layer 5 has a second horizontal placement frame 7. The second placement frame 7 is fixedly connected to a sonar 8, which passes through the output layer 5. The overlapping part of the sonar 8 and the output layer 5 has a sealing gasket 9. Several side supports 10 are bonded to the outside of the flexible layer 4. The cross-section of any side support 10 is rectangular, and the side supports 10 form a circular matrix along the flexible layer 4. When the flexible layer 4 is in a natural state, the side supports 10 are in a contracted state.

[0029] Please refer to Figure 3 The suspension layer 3 has a clockwise threaded groove 11 inside, and the output layer 5 has a counterclockwise threaded groove 12 inside. The clockwise threaded groove 11 and the counterclockwise threaded groove 12 are connected by a bolt 13. The tail of the bolt 13 is provided with an ejector motor 14, which is fixed to the first placement frame 6.

[0030] The outer surface of the suspension layer 3 has a storage box 15 with a through hole. One end of the side support 10 passes through the storage box 15 along the through hole, and the other end of the side support 10 is bonded to the outer surface of the output layer 5. The storage box 15 has a trapezoidal block 16 inside the through hole. The bottom of the trapezoid is close to the hanging ring 1, and the thickness of the trapezoid gradually increases from the bottom to the top.

[0031] The specific implementation process is as follows: In general, when this technical solution is used, the characteristics of sonar 8 combined with the protective cage 2 in the water to propagate and reflect within underwater sediments can be used to detect the underwater strata and form a profile map of the underwater strata.

[0032] To achieve the detection objective, this technical solution can adopt two modes: one is the towing mode, which uses the onboard measurement equipment of the detection ship to explore a local area; the other is to drop the device into a specific area for free exploration (such as a Lagrange circulation detector). In the free exploration process, it is necessary to solve the problem of the device's floating and sinking depth in order to realize the detection of strata at different depths. Therefore, during use, the ejector motor 14 can be used to drive the bolt 13 to rotate. At this time, during the downward rotation of the bolt 13, it will pass through the clockwise thread groove 11 and the counterclockwise thread groove 12.

[0033] With different spiral directions of the threaded grooves, the suspension layer 3 and the output layer 5 come together (squeezing towards the middle flexible layer 4). The flexible layer 4, which is squeezed, becomes flat, thereby increasing the width of the flexible layer 4. The increased flexible layer 4 will increase the buoyancy of the device, thereby causing the device to float, thus changing the floating degree of the device to achieve a change in position.

[0034] Compared with existing technologies that rely on floating and changing, this technical solution utilizes the side support 10 bonded to the flexible layer 4 to achieve expansion and contraction. When the flexible layer 4 is in its natural state, the side support 10 is in a contracted state, at which point the volume of the device is at its minimum, and therefore the buoyancy force on the device is also at its minimum. However, when the bolt 13 rotates downwards, the flexible layer 4 is compressed, and at this time the side support 10 diverges and expands, thus the side support 10 acts as a buoyancy device to make it float.

[0035] In this technical solution, the storage box 15 is used to limit the extension direction and extent of the side support 10. When the flexible layer 4 contracts, the side support 10 moves downward along the storage box 15. At this time, the junction of the side support 10 and the trapezoidal block 16 serves as a fulcrum. When the width of the flexible layer 4 widens and expands the side support 10, the side support 10 spreads out in a direction away from the device along the fulcrum. When the flexible layer 4 returns to its original position, the side support 10 moves upward along the storage box 15. At this time, the storage box 15 limits the return direction of the side support 10, preventing the water flow from disturbing the side support 10.

[0036] Example 2

[0037] The difference between this embodiment and the previous embodiment is that the suspension layer 3 has a built-in power module 17, a signal transmission module 18, and a signal processing module 19. The signal processing module 19 is used to process the signals received and fed back by the sonar 8, and the signal transmission module 18 is used to transmit the information generated by the signal processing module 19. The sonar 8 is connected to a beam stabilization system, which includes a transducer array 20, a speed sensor 21, and a pitch sensor 22. The transducer array 20 and the speed sensor 21 combine to form the transmission aperture of the sonar 8. The pitch sensor 22 is used to measure the current direction of motion. The ejector motor 14 is equipped with an activation button, which is used to drive the ejector motor 14 to run according to the signal sent by the signal transmission module 18.

[0038] The specific implementation process is as follows: In actual operation, the circuit components of this device operate using a towed, mobile method. The sonar 8, under the operator's control, transmits acoustic signals from the transducer array 20 (transmitting array). After reflection off the seabed, the signals are received by the transducer array 20 (receiving array) and preprocessed, including filtering and amplification. Finally, the signal processing module 19 records the points at different depths corresponding to different times. At the end of the mobile operation, these points are connected to form lines reflecting the seabed and strata interfaces. From this intuitive and continuous underwater strata profile, layering and grayscale identification allow for geological analysis.
