[0042] The key components of the impact sounding system will be described in detail below.

[0043] 1.2 Winch and automatic winding and unwinding unit

[0044] The structure of the winch and the automatic winding and unwinding unit is shown in the following figure:

[0045] Figure 2 The structure diagram of the winch winding and unwinding unit is shown in the following figure,

[0046] The function of the winch structure is to control the release and recovery of the impact sounding probe 4. The structure of the winding and unwinding winch 1 is installed on the unmanned ship 7 through the winch frame 12 and is automatically controlled through the winch control unit 13. The winch drum 11 is installed on the winch frame 12 and is provided with a clutch device. The winding and unwinding steel cable 6 is led out from the winch drum 11, passes through the guide pulley 2, passes through the launching device 3 and is connected to the tail end of the probe. A tension sensor is installed on the guide pulley 2 to detect the tension of the winding and unwinding steel cable 6, and then the winding and unwinding of the winch forms a feedback to control the winding and unwinding speed of the winding and unwinding steel cable 6.

[0047] Considering the operation depth of the intelligent unmanned equipment of the project, a double-mode control method is adopted to design the control system of the winch. The operation water depth of the unmanned equipment in the project is 0-50m. In the operation water depth range of 0-5m, the launching device 3 has enough capacity to energize the impact sounding probe 4, the probe can reach the seabed with enough speed by the launching device 3, and the probe can impact the seabed at a rated speed. When the depth release is in the depth range, the winch winding and unwinding system is switched to full-speed mode, the clutch device on the winch is released, and the winch drum 11 can rotate freely. When releasing, the locking mechanism 8 is released, the probe is pushed out by the spring 81, and the launching is completed. In this mode, the winch and the locking structure form interlocking, the locking mechanism 8 cannot be released when the winch clutch is not released, which ensures the smooth release of the impact probe.

[0048] When the working water depth is 5-50m, due to the water resistance, the probe released by the ejection will not reach the seabed at a sufficient speed, at this time the method of uniform speed mode quota full speed mode will be used to release the probe. In this mode, the winch keeps pulling the impact probe before release. After the lock mechanism 8 is released, the winch continues to pull the impact probe, and the tension sensor on the guide pulley 2 detects the tension of the release cable 6, which forms a feedback control with the winch, so that the probe slowly leaves the ejection device 3 at a constant speed, and forms a swell compensation in the subsequent release process, ensuring that the probe is released at a constant speed, preventing the probe from swinging uncontrollably and affecting the accuracy of the subsequent probe release. When the probe is lowered to 5m from the seabed, the winch switches to full speed mode, and then the probe is free-falling, so that it reaches the rated speed when it contacts the seabed. After completing the penetration of the impact probe, the winch is reversed to recover the probe for the next station work.

[0049] In this embodiment, the winch and its release control system will be further designed. On the one hand, the winch motor will be selected to have enough pulling force, and on the other hand, the winch control system in the upper mode will be further designed to have good automatic release control at different working depths. In addition, according to relevant experience and preliminary calculation results, when the probe is released at a height of 5m from the seabed in water, the probe can reach the rated speed when it contacts the seabed, so the water depth of 5m is set as the release mode switching boundary. Further research and experiments will be conducted to further determine the appropriate mode switching depth.

[0050] 1.3 Impact probe ejection unit

[0051] The impact probe ejection unit is an important structure for the probe, and its structure is shown in the following figure.

[0052] Figure 3 The impact probe ejection unit structure diagram,

[0053] The top of the impact probe ejection device 3 is an energy storage spring 31, and the release cable 6 passes through the middle of the energy storage spring 31 and is connected to the tail end of the impact probe. When the release cable 6 is tensioned, the energy storage spring 31 is compressed, thereby achieving the purpose of energy storage. The lower end of the energy storage spring 31 is an ICL coil, which is used to realize wireless transmission of probe data, and the data is transmitted through the transmission cable. The lock mechanism 8 is installed below the ICL coil and is used to lock the impact probe. The bottom of the launch unit is a horn-shaped opening for guiding the recovery of the probe.

[0054] The specific structure of the lock mechanism part is shown in the following figure:

[0055] Figure 4 The lock mechanism structure diagram,

[0056] As Figure 4 shown, the ICL coil is divided into a transmitting coil and a receiving coil, the transmitting coil is installed at the tail of the impact probe, after the probe is recovered, the two coils are coupled, and data transmission can be performed.

[0057] The locking mechanism 8 is divided into three parts, a spring 81, a lock tongue 82, and an action unit 83. The spring 81 is installed between the lock tongue 82 and the action unit 83, continuously pushing out the lock tongue 82, so that the locking mechanism 8 naturally maintains the locked state. One end of the lock tongue 82 passes through the spring 81 and is connected with the action unit 83. The action unit 83 can drive the lock tongue 82 to be recovered, so that the locking mechanism 8 is released, the probe is released, and the lock tongue 82 is reset by the spring 81 after the action is completed. The lock tongue 82 is a square block with an inclined surface, and a step structure for locking is provided on the probe. The flat surface of the lock tongue 82 is in contact with the step, so that the probe cannot be ejected. When the lock tongue 82 is separated from the step, the release of the probe is completed. Because the lock tongue 82 has an inclined surface, the probe will be automatically pushed out when it is recovered. When the probe reaches the rising position, the lock tongue 82 will be pushed out by the spring 81, and the locking is automatically completed.

[0058] In this embodiment, the energy storage device and the locking mechanism 8 will be further designed. On the one hand, the appropriate spring will be selected through analysis, calculation and force simulation, so that the energy storage mechanism can provide sufficient kinetic energy for the probe. On the other hand, the locking mechanism 8 will be further designed, and the appropriate material will be selected for further structural design, so that the locking mechanism 8 can complete the release and automatic locking functions, and can withstand the strong pressure of the energy storage device in the energy storage state, so that it is solid and reliable.

[0059] 1.4 Impact sounding probe 4

[0060] A new type of impact sounding probe 4 will be developed in this subject, and the mechanical structure and electronic acquisition system of the probe will be further researched, so that the probe has high-speed and high-precision acquisition performance, and has reasonable mechanical structure, high strength, high durability, and other characteristics, so that the impact sounding work can be completed well. The structure of the impact sounding probe 4 is shown in the following figure:

[0061] Figure 5 is a structural diagram of the impact sounding probe,

[0062] The impact type sounding probe 4 is based on the standard 10cm2probe structure, with a 60° pointed cone at one end, and sensors for measuring cone tip resistance, sidewall friction, pore water pressure, probe acceleration, and probe attitude, which collect data through the collection module 41. The probe uses a self-contained structure and is equipped with a battery module 42, which works independently of other equipment. The collected data is temporarily stored in the probe. After the collection is complete, the data in the collection module 41 is transmitted through the data transmission cable 43 and sent by the ICL launch coil at the end of the probe. The central part of the probe is a lead pipe, which provides counterweight for the probe and increases the penetration ability of the probe in the stratum. The lead pipe is hollow, and the data transmission cable 43 can pass through it. The probe is equipped with four flow guide plates 46 at its center of gravity, which can keep the probe vertical during the falling process and enable the probe to collect accurate data.

[0063] Device installation and preparation

[0064] The winch is firmly installed on the unmanned ship 7 through the winch frame 12 to ensure the stability of the winch. The guide pulley 2 is installed, and the steel cable 6 is correctly wound around the guide pulley 2, connected to the ejection device 3 and the tail end of the impact type sounding probe 4. Check whether the energy storage spring 31, locking mechanism 8, and ICL coil of the ejection device 3 are installed correctly and function normally. Install the impact type sounding probe 4 from the horn at the bottom of the ejection device 3, and ensure that the locking tongue 82 is correctly locked with the step structure on the probe. Charge the battery module 42 of the impact type sounding probe 4, and check whether the sensors and collection module 41 are working normally.

[0065] Different water depth operation process

[0066] 0-5m water depth operation: when the unmanned ship 7 reaches the designated operation area and the water depth is within the range of 0-5m, start the winch control unit 13, switch the winch winding system to full speed mode, release the clutch device on the winch, and the winch drum 11 is in free rotation state. At this time, the locking mechanism 8 is released, the energy storage spring 31 pushes the impact type sounding probe 4 out of the ejection device 3, and the ejection is completed. During the ejection process, due to the interlocking mechanism of the winch and the locking structure, the release of the impact probe is ensured to proceed smoothly. The probe falls to the seabed at a sufficient speed and performs impact sounding at the rated speed. After completing the sounding, the winch is reversed, the probe is retrieved into the ejection device 3 through the steel cable 6, the locking tongue 82 is automatically ejected to complete the locking, and the next operation is prepared.

[0067] 5-50m water depth operation: when the water depth is 5-50m, the locking mechanism 8 is kept in the locked state before releasing the impact type sounding probe 4, and the winch pulls the probe through the steel cable 6. When ready to release, the locking mechanism 8 is released, and the winch detects the tension of the steel cable 6 through the tension sensor on the guide pulley 2, forming a feedback control with the winch. The winch continuously pulls the impact probe, so that the probe slowly and uniformly leaves the ejector 3 and performs surge compensation during subsequent lowering, ensuring that the probe is uniformly and stably lowered. When the probe is lowered to 5m from the seabed, the winch switches to full speed mode, allowing the probe to free fall and impact the seabed at a rated speed. After completing the sounding, the probe is also recovered by reversing the winch.

[0068] Data acquisition and transmission

[0069] When the impact type sounding probe 4 is performing sounding operations, the sensors at the front end of the probe collect real-time data such as cone tip resistance, sidewall friction, pore water pressure, probe acceleration, and probe attitude. These data are collected by the collection module 41 and temporarily stored in the storage unit in the probe. After completion of the collection, the data are transmitted to the ICL transmitting coil at the end of the probe through the data transmission cable 43, and the ICL receiving coil in the middle of the ejector 3 receives the data, which are then transmitted to the control center on the unmanned ship 7 through the measurement and control cable 5 for analysis and processing.
