[0002] With the development of marine engineering, the need for testing the mechanical properties of marine sediments is becoming more and more prominent. At present, static sounding is often used to survey marine soil layers, which involves pressing a sounding rod with a sounding probe into the soil layer using a pressure device to measure the penetration resistance, pore water pressure and other parameters of the soil layer, thereby determining some basic physical and mechanical properties of the soil layer, such as the deformation coefficient of the soil, the allowable bearing capacity of the soil, etc.

[0020] The technical solution of the present invention will be further described below through specific embodiments with reference to the drawings.

[0021] 1 to 3, an embodiment of the present invention provides a seabed lateral exploration introduction device capable of introducing an exploration mechanism 30 laterally into seabed sediments. The seabed lateral exploration introduction device includes a support assembly, an introduction assembly 20, and an exploration mechanism 30, the support assembly includes a rope and a support holder 11, the support holder 11 is connected to the rope, the introduction assembly 20 is provided on the support holder 11, the introduction assembly 20 includes an introduction tube 21 and a driving plate 22, an introduction passage is formed inside the introduction tube 21, the introduction passage extends along the horizontal direction, an insertion port is provided at one end of the introduction passage, the driving plate 22 is provided at the other end of the introduction passage, the exploration mechanism 30 is provided inside the introduction tube 21, and the driving plate 22 can move along the introduction passage to push the exploration mechanism 30 to separate from the introduction tube 21 from the insertion port.

[0022] The exploration mechanism 30 is placed in the introduction tube 21, which provides a protective function for the exploration mechanism 30. As the rope lowers the support holder 11, the introduction tube 21 is lowered along with the support holder 11. After the introduction tube 21 enters the seabed sediments, the driving plate 22 moves along the introduction passage to push the exploration mechanism 30 away from the introduction tube 21 through the insertion port. Since the introduction passage extends horizontally, the exploration mechanism 30 is introduced into the seabed sediments along the lateral direction, and the exploration mechanism 30 moves through the seabed sediments to perform lateral exploration.

[0023] In order to make it easier to place the exploration mechanism 30, the introduction tube 21 may be configured as a separate mechanism. Specifically, the introduction tube 21 includes a first cylinder body and a second cylinder body that are engaged vertically, and when it is necessary to place the exploration mechanism 30 in the introduction tube 21, the first cylinder body and the second cylinder body are removed, the first cylinder body is opened, the exploration mechanism 30 is placed on the second cylinder body, and then the first cylinder body is attached. The first cylinder body and the second cylinder body can be connected with a bolt.

[0024] Wherein, the driving plate 22 can be driven by a hydraulic cylinder, the piston rod of which is connected to the driving plate 22 to move the driving plate 22 along a straight line.

[0025] The support holder 11 is balanced as much as possible during the process of being lowered, and because there are multiple connection points between the ropes and the support holder 11, the support holder 11 is balanced.

[0026] In this embodiment, the support holder 11 enters seawater and comes into contact with the seabed sediments, and at least a part of the support holder 11 sinks into the seabed sediments under the action of gravity, moving the introduction tube 21 to sink into the seabed sediments. The introduction tube 21 may be provided at the bottom position of the support holder 11 so as to facilitate sinking into the seabed sediments. After the support holder 11 comes into contact with the seabed sediments, the seabed sediments provide a certain support to the support holder 11, causing the support holder 11 to gently descend.

[0027] In another embodiment, the support holder 11 can be provided with a lowering assembly, which is connected to the introduction tube 21 and can move the introduction tube 21 vertically downward. Specifically, the lowering assembly can be a hydraulic cylinder, and the piston rod of the hydraulic cylinder can move the introduction tube 21. After the support holder 11 stops moving due to the action of gravity, if it does not reach the searching position of the searching mechanism 30, the lowering assembly can drive the introduction tube 21 to move vertically downward until it reaches the searching position.

[0028] Providing a counterweight on the support holder 11 makes it easier for the support holder 11 to balance, and on the other hand, increases the gravity of the support holder 11, making it easier for the support holder 11 to sink in the sediment. If the support holder 11 stops moving due to the effect of gravity and does not reach the exploration position of the exploration mechanism 30, the support holder 11 can be retrieved by a rope, and a counterweight can be added or removed from the support holder 11 before the support holder 11 is lowered again, and the lowering or retrieval can be repeated until the introduction tube 21 reaches the exploration position. Specifically, a pressure sensor can be provided in the introduction tube 21, and the position of the introduction tube 21 can be determined by a signal fed back from the pressure sensor.

[0029] The injection port is provided with a baffle plate 23 that can move along a straight line to open or close the injection port. During the process of lowering, the baffle plate 23 closes to act as a stopper for the exploration mechanism 30 and prevents the exploration mechanism 30 from escaping from the introduction tube 21, and when it is necessary to introduce the exploration mechanism 30 into the seabed sediments, the baffle plate 23 opens to avoid interfering with the movement of the exploration mechanism 30.

[0030] In this embodiment, the cross section of the introduction passage is circular, and the baffle plate 23 is movable along the radial direction of the introduction passage. The movement of the baffle plate 23 can be driven by a hydraulic cylinder, the cylinder block of which is connected to the introduction tube 21, and the piston rod of the hydraulic cylinder is connected to the baffle plate 23 and drives the baffle plate 23 to move.

[0031] The exploration mechanism 30 according to the present embodiment is used for lateral exploration, and basically performs exploration in a horizontal plane. However, the exploration mechanism 30 needs to perform exploration in multiple directions within a certain range in order to obtain more data, that is, to perform exploration in multiple directions within a circular range centered on the support holder 11.

[0032] The seabed lateral exploration introduction device further comprises an adjustment assembly 40, which comprises a support plate 41 and a rotating shaft 42, the introduction tube 21 is mounted on the support plate 41, the rotating shaft 42 is connected to the support plate 41, and the rotating shaft 42 can rotate about its own axis to adjust the insertion angle of the introduction tube 21. When the support plate 41 is rotated by the rotating shaft 42, the introduction tube 21 can be rotated, and the introduction tube 21 can be rotated to different positions to orient the insertion port in different directions, making it easy to insert the exploration mechanism 30 at multiple angles and meeting the needs of exploration. Wherein, the rotating shaft 42 can be driven by a motor, and the motor is connected to the rotating shaft 42 via a reduction mechanism, which may be a gear mechanism, and will not be described here repeatedly.

[0033] When the introduction cylinder 21 rotates, the baffle plate 23 and the drive plate 22 also rotate accordingly, so that the hydraulic cylinder connected to the drive plate 22 is also provided on the support plate 41 .

[0034] The support plate 41 is provided with a plurality of telescopic rods 43, which are arranged at intervals along the length of the introduction tube 21. The telescopic rods 43 are connected to the introduction tube 21, and the angle between the introduction tube 21 and the horizontal plane can be adjusted by the telescopic rods 43. Specifically, when two telescopic rods 43 are provided, the telescopic lengths of the two telescopic rods 43 are controlled to be different, thereby realizing the change of the angle between the introduction tube 21 and the horizontal plane. When four telescopic rods 43 are provided, the four telescopic rods 43 are arranged at the four corners of a rectangle under the introduction tube 21, and the four telescopic rods 43 can be hingedly connected to the introduction tube 21. The telescopic rods 43 play a supporting role and can ensure the stability of the introduction tube 21. The two telescopic rods 43 located at the front end telescopically extend and retract synchronously, and the two telescopic rods 43 located at the rear end telescopically extend and retract synchronously, thereby realizing the change of the angle between the introduction tube 21 and the horizontal plane. Among them, the telescopic rods 43 may be the piston rods of a hydraulic cylinder.

[0035] When the support holder 11 is stopped in the seabed sediments by the action of gravity, a stopper assembly can be provided to ensure the stability of the support holder 11, and the stopper assembly is provided on the support holder 11, and the stopper assembly includes several stopper rods, and the several stopper rods can protrude and retract from the support holder 11. When the support holder 11 is stopped in the seabed sediments by the action of gravity, the stopper rods protrude from the support holder 11 to increase the contact area with the sediments, play an anchoring role, and make the support holder 11 more stable. Before the support holder 11 is retrieved, the stopper rods are retracted to facilitate retrieval. Specifically, the stopper rods can be provided at the bottom of the support holder 11, and the stopper rods can protrude downwards, and the harder the sediments are, the more the stability can be guaranteed. The stopper rods can be moved along a straight line by the drive of a hydraulic cylinder, and will not be described again here.

[0036] 4 to 8, the exploration mechanism 30 includes a main body 31, a sounding assembly 32, and an anchor assembly 33. The main body 31 includes two support tubes 311 connected in sequence from front to rear along a first axial direction. A telescopic assembly 312 is provided between the two support tubes 311. The telescopic assembly 312 can extend and retract along the first axial direction. The front end of the main body 31 faces the inlet of the introduction tube 21. The sounding assembly 32 is provided at the front end of the main body 31 and is connected to the support tubes 311. Each support tube 311 is provided with one set of anchor assemblies 33. The anchor assembly 33 includes at least two anchor rods 331. The anchor rods 331 are slidably connected to the support tubes 311. The anchor rods 331 can protrude and retract along the radial direction of the support tubes 311.

[0037] When the exploration mechanism 30 is introduced into the seabed sediment, the exploration mechanism 30 is placed horizontally, that is, the first axis extends horizontally, the anchor rod 331 protrudes along the radial direction of the support tube 311, and then can play an anchoring role, and the corresponding support tube 311 is in an anchored state, and the anchor rod 331 retracts along the radial direction of the support tube 311, and the corresponding support tube 311 is in a released state, and the two support tubes 311 can be switched between an anchored state and a released state, and the support tube 311 in the anchored state plays a supporting role, and the support tube 311 in the released state can move with the movement of the telescopic assembly 312, and the axle of the support tube 311 can be moved. By switching between the anchor state and the released state in coordination with the extension or contraction of the telescopic assembly 312, the exploration mechanism 30 advances laterally on the seabed, thereby enabling the sounding assembly 32 to perform lateral exploration.

[0038] The exploration mechanism 30 can perform lateral exploration on the seabed, while the seabed sediments provide support for the main body 31, while the main body 31 can be provided with a counterweight, so that the exploration mechanism 30 can be held in a lateral position without tilting due to one end being heavy and the other end being light. It can be seen that the exploration mechanism 30 has already been tested multiple times on land before being lowered into the seabed, and the tests are performed in a simulated seabed environment to ensure the stability of the lateral movement on the seabed.

[0039] The exploration mechanism 30 can move laterally on the seabed, specifically, because the anchor rod 331 of the anchor assembly 33 in one support tube 311 protrudes, causing the corresponding support tube 311 to be in an anchored state, and the anchor rod 331 of the anchor assembly 33 in the other support tube 311 retracts, causing the corresponding support tube 311 to be in a released state, and the support tube 311 in the released state moves forward a set distance by contracting or extending the telescopic assembly 312, and the support tube 311 in the released state is switched to an anchored state, and the support tube 311 in the anchored state is switched to a released state, and the support tube 311 in the released state moves forward a set distance by contracting or extending the telescopic assembly 312, and the above process is repeated, causing the sounding assembly 32 to move forward.

[0040] The sounding assembly 32 and the existing vertical sounding device have the same sounding principle and are almost similar in structure. The sounding assembly 32 includes a probe rod 321 and a probe 322. The probe 322 has a cone-shaped tip, and the probe rod 321 is equipped with necessary sensors, such as a pressure sensor and a speed sensor, to measure parameters such as the penetration resistance and pore water pressure of the soil layer during the movement process, thereby determining some basic physical and mechanical properties of the soil layer.

[0041] The anchor assembly 33 further includes a first drive assembly, which is mounted on the support tube 311 and connected to the anchor rod 331, and which is capable of driving the anchor rod 331 to move.

[0042] In this embodiment, the first driving assembly includes a first motor 3321, a first lead screw 3322, and a first guide block 3323, the output shaft of the first motor 3321 is connected to the first lead screw 3322, the first guide block 3323 is slidably connected to the support tube 311 and screw-connected to the first lead screw 3322, the outer circumferential surface of the first guide block 3323 has a tapered surface, a guide groove is provided on the tapered surface, and one end of the anchor rod 331 is slidably provided in the guide groove. The first motor 3321 rotates the first lead screw 3322, thereby moving the first guide block 3323 linearly along the first lead screw 3322, and since the guide groove is provided on the tapered surface, the anchor rod 331 is pushed and moved during the movement of the first guide block 3323. Specifically, the movement direction of the anchor rod 331 is along the radial direction of the first guide block 3323, the tapered surface has a small diameter end and a large diameter end, when the anchor rod 331 is located at the small diameter end of the tapered surface, it moves along with the first guide block 3323, when the anchor rod 331 moves to the large diameter end of the tapered surface, the large diameter end has a larger diameter, so it pushes the anchor rod 331 outward, thereby causing the anchor rod 331 to protrude, and when it moves in the opposite direction, it causes the anchor rod 331 to retract.

[0043] The cross-sectional shape of the guide groove may be T-shaped, which acts as a stopper for the anchor rod 331 and allows the anchor rod 331 to be smoothly retracted. It is possible.

[0044] The sliding connection between the first guide block 3323 and the support tube 311 mainly serves as a stopper for the first guide block 3323, preventing rotation of the first guide block 3323. Specifically, a first guide rod 3324 is provided inside the support tube 311, and the first guide block 3323 and the first guide rod 3324 are slidably connected to each other.

[0045] In another embodiment, the first drive assembly may include a first hydraulic cylinder, the first hydraulic cylinder including a first cylinder block and a first piston rod, the first cylinder block being disposed within the support tube 311, and the first piston rod being connected to the anchor rod 331. The extension and contraction of the first piston rod causes the anchor rod 331 to move. It can be understood that the support tube 311 is provided with a through hole for the anchor rod 331 to be disposed therethrough.

[0046] One end of the anchor rod 331 is located in the support tube 311, and the other end is provided with a support block 333. By providing the support block 333, the contact area with the seabed sediments can be increased and the anchor can be stabilized. The shape of the support block 333 can be set according to actual needs and is not limited here.

[0047] An accommodating groove 3111 is opened on the outer wall of the support tube 311, and when the anchor rod 331 moves to the retracted position, the support block 333 is located in the accommodating groove 3111. The accommodating groove 3111 provides a space for the support block 333, so that when the support block 333 is in the retracted position, it does not protrude from the surface of the support tube 311, and the support block 333 does not generate resistance when the support tube 311 moves forward.

[0048] In this embodiment, each set of anchor assemblies 33 includes three anchor rods 331 that are evenly spaced around the circumference of the support tube 311 .

[0049] The telescopic assembly 312 includes a telescopic tube 3121 and a second drive assembly, the telescopic tube 3121 is provided between two adjacent support tubes 311, and the second drive assembly is provided within the telescopic tube 3121, and the second drive assembly can drive the two support tubes 311 to move toward or away from each other. When the two support tubes 311 move toward each other, the telescopic tube 3121 is compressed, and when the two support tubes 311 move away from each other, the telescopic tube 3121 is extended.

[0050] In this embodiment, the telescopic tube 3121 is a corrugated tube, and the ends of the corrugated tube and the support tube 311 are locked with bolts.

[0051] In this embodiment, the second drive assembly includes a second motor 3122, a second lead screw 3123, and a second guide block 3124, the second motor 3122 is mounted on one support tube 311, and the output shaft of the second motor 3122 is connected to the second lead screw 3123, the second guide block 3124 is mounted on the other support tube 311, and is slidably connected to the support tube 311 in which the second motor 3122 is located, and the second guide block 3124 is threadedly connected to the second lead screw 3123. The second motor 3122 rotates the second lead screw 3123, thereby linearly moving the second guide block 3124 along the second lead screw 3123 to move the support tube 311 in which the second guide block 3124 is located. Specifically, when the second guide block 3124 moves in a direction toward the second motor 3122, the two support tubes 311 move closer to each other, and when the second guide block 3124 moves in a direction away from the second motor 3122, the two support tubes 311 move away from each other.

[0052] The sliding connection between the second guide block 3124 and the support tube 311 mainly serves as a stopper for the second guide block 3124, preventing rotation of the second guide block 3124. Specifically, a second guide rod 3125 is provided inside the support tube 311, and the second guide block 3124 and the second guide rod 3125 are slidably connected.

[0053] In another embodiment, the second drive assembly may include a second hydraulic cylinder, the second hydraulic cylinder including a second cylinder block and a second piston rod, one of the two support tubes 311 is provided with the second cylinder block and the other support tube 311 is connected to the second piston rod. The extension and contraction of the second piston rod moves the two adjacent support tubes 311 toward or away from each other.

[0054] In this embodiment, the two support tubes 311 are respectively the front support tube and the rear support tube, and the sounding assembly 32 is provided at the front end of the front support tube. When it is necessary to move forward, the anchor rod 331 of the anchor assembly 33 at the front support tube is extended to make the front support tube in an anchored state, the anchor rod 331 of the anchor assembly 33 at the rear support tube is retracted to make the rear support tube in a released state, the telescopic assembly 312 is shortened to make the rear support tube move forward a set distance, the anchor rod 331 of the anchor assembly 33 at the rear support tube is extended to make the rear support tube switch to an anchored state, the anchor rod 331 of the anchor assembly 33 at the front support tube is retracted to make the front support tube switch to a released state, the telescopic assembly 312 is extended to make the front support tube move forward a set distance, and the above process is repeated.

[0055] When the exploration mechanism 30 performs lateral exploration on the seabed, the steps include: S10, in which the anchor rod 331 of the anchor assembly 33 in one support tube 311 protrudes to place the corresponding support tube 311 in an anchored state, and the anchor rod 331 of the anchor assembly 33 in the other support tube 311 retracts to place the corresponding support tube 311 in a released state; S20, in which the telescopic assembly 312 contracts or extends to move the support tube 311 in the released state forward a set distance; S30, in which the support tube 311 in the released state is switched to the anchored state and the support tube 311 in the anchored state is switched to the released state; S40, in which the telescopic assembly 312 contracts or extends to move the support tube 311 in the released state forward a set distance; and S50, in which steps S30 and S40 are repeated and the sounding assembly 32 is moved forward.

[0056] By switching the support tube 311 between the anchored state and the released state in coordination with the extension or contraction of the telescopic assembly 312, the exploration mechanism 30 advances laterally on the seabed, thereby enabling the sounding assembly 32 to realize lateral exploration.

[0057] The motors, sensors, etc. require electricity. A drum is provided on the support holder 11, a cable is connected to the detection mechanism 30, and the cable can be wound around the drum, and a cable hole is provided in the drive plate 22 through which the cable passes.
