Description

Technical Field

[0001] The present invention relates to the field of marine engineering applications, and in particular to an intelligent survey device for strata and submarine tunnels. Background Art

[0002] In the fields of undersea tunnel construction, maintenance, and marine science research, it is crucial to accurately obtain information such as the geological structure of the strata and seabed, the seawater environment, etc. Before tunnel construction, it is necessary to analyze the changes in parameters such as the salinity, temperature, and pH of seawater to infer geological information such as the rock type and fault distribution of the seabed strata, which can provide important clues for geological surveys and improve the accuracy of geological surveys. Various pollutants may be generated during tunnel construction, such as construction wastewater and waste residue. If these pollutants are discharged directly into the ocean without treatment, they will pollute the marine water quality. After the tunnel is built, changes in marine water quality may cause corrosion and damage to the tunnel structure and equipment. For example, factors such as the salinity and pH in seawater will affect the service life of the tunnel's concrete structure and metal equipment.

[0003] Traditional seawater sampling methods struggle to ensure sample stability during the collection process, and are prone to shaking and shifting, leading to sample contamination or leakage, impacting sample quality and the accuracy of subsequent analytical results. Furthermore, when sampling seawater from different locations in subsurface submarine tunnels, it's difficult to efficiently obtain samples from multiple designated locations, consuming significant time and manpower and making it difficult to ensure sample representativeness. Furthermore, seabed algae easily adhere to the device's surface, particularly areas like the mounting cover. This algae adhesion not only increases the device's weight but can also affect its normal operation, such as clogging the water inlet and affecting sensor sensitivity, reducing the device's service life and survey effectiveness. To address these issues, we propose an intelligent survey device for subsurface submarine tunnels. Summary of the Invention

Then, the second electric telescopic rod 28 is controlled to perform a telescopic operation. The telescopic end of the second electric telescopic rod 28 pushes the support drill rod 29 to insert it into the seabed.

[0047] In this embodiment, a spirit level 18 is fixedly connected to one side wall of the base plate 1, a hole is opened on the top side wall of the base plate 1, and a first motor 13 is fixedly connected to the inner wall of the hole, a first transmission shaft 14 is provided at the output end of the first motor 13, a first electric telescopic rod 15 is provided at the top of the first transmission shaft 14, and two arc rods 16 are provided on the outer side wall of the telescopic end of the first electric telescopic rod 15, and multiple holes are opened on the outer side walls of the two arc rods 16, and a sonar 17 is fixedly connected to the inner wall of the corresponding holes.

[0048] Specifically, a level gauge 18 on one side wall is used to determine whether the device is in a horizontal state, so that the length of one or more supporting drill rods 29 is fine-tuned to ensure that the device is in a horizontal state, and multiple sonars 17 are started to operate. The sonars 17 emit sound waves of a specific frequency and receive reflected sound wave signals. Based on information such as the propagation time and reflection intensity of the sound waves, the sonars 17 conduct detailed detection and analysis of the relevant geological structure, object distribution, etc. of the stratum and submarine tunnel, and can also drive away schools of fish.

[0049] It should be noted that the present invention is an intelligent survey device for strata and submarine tunnels. The user carefully places multiple collecting tubes 37 in the four bearing grooves 32 opened on the top side wall of the fixing box 31, and accurately inserts the four positioning plates 38 on the outer side wall of the collecting tube 37 into the positioning groove 33. Then, the multiple third electric telescopic rods 34 at both ends of the inner side wall of the positioning groove 33 are activated, and the telescopic ends of the third electric telescopic rods 34 push the clamping plate 35 to move toward the positioning plate 38 until the positioning plate 38 is firmly clamped, thereby fixing the collecting tube 37 in the bearing groove 32. Then, the positioning cover 51 is installed on the top of the fixing box 31, so that the inner walls of the multiple first positioning holes 52 on the positioning cover 51 are in close contact with the outer walls of the four sleeves 39 respectively, and the collecting tube 37 is further positioned to ensure its stability during the sampling process. Finally, the installation cover 61 is threadedly connected to the inner wall of the installation groove 191, so that the bottom end of the installation cover 61 is in close contact with the top of the positioning cover 51, thereby fixing the positioning cover 51.

[0050] Subsequently, the device is placed on the seabed, and the walking assembly 12 installed at the bottom end of the bottom plate 1 is used to move the entire stratum submarine tunnel intelligent survey device to the predetermined seabed survey position. The walking assembly 12 is a crawler walking device adapted to the seabed environment, so that the device can smoothly reach the designated location. Subsequently, the four second motors 21 located on the top side wall of the bottom plate 1 are started. The second motor 21 starts to run, and its output end drives the support shell 23 to rotate from the initial storage state to a ninety-degree angle. Subsequently, the third motor 24 on the side wall of one end of the support shell 23 is turned on, and the output end of the third motor 24 drives the support rod 26 Rotate the support rod 26 to a vertical downward position, then control the second electric telescopic rod 28 to perform telescopic operation, the telescopic end of the second electric telescopic rod 28 pushes the support drill rod 29 to insert it into the seabed. During the insertion process, the fourth motor 27 is started at the same time to ensure that the device is firmly supported. At the same time, the level meter 18 on one side wall is used to determine whether the device is in a horizontal state, so as to ensure that the device is in a horizontal state by fine-tuning the length of one or more support drill rods 29, thereby preventing the device from shaking when impacted by seawater, and providing a stable foundation for subsequent precise surveys.

[0051] After arriving at one of the designated locations, the two fourth electric telescopic rods 69 on the inner top side wall of the installation cover 61 are started to extend, so that the third baffle 691 fixedly connected at the two telescopic ends moves downward, so that the third baffle 691 no longer blocks the multiple second water inlet holes 692, thereby allowing seawater to enter the interior of the installation cover 61 from the multiple second water inlet holes 692. At the same time, the third baffle 691 moves downward, thereby causing the second protrusion 591 to move downward, so that the bottom end of the second signal sensor 59 contacts the top end of the first signal sensor 57 and triggers an electrical signal, causing the fifth motor 53 to start running, driving the fourth transmission shaft 54 ​​and the guide plate 55 to rotate forty-five degrees, after which the fifth motor 53 stops running. At this time, the guide plate 55 moves to one of the collecting holes. 391 , and the water level in the collecting tube 37 gradually rises. When the water level reaches the height of the first water level sensor 36 at this time, an electrical signal is sent, and the fourth electric telescopic rod 69 drives the third baffle 691 to move upward and reset, so that the third baffle 691 is reset. The plurality of second water inlet holes 692 are blocked again, so that the bottom end of the third baffle 691 no longer presses the second protrusion 591, and the second protrusion 591 is reset by the elastic force of the second spring 58, driving the second signal sensor 59 to move upward, so that the bottom end of the second signal sensor 59 is no longer in contact with the top end of the first signal sensor 57, and triggering an electrical signal to make the fifth motor 53 start running again, driving the fourth transmission shaft 54 ​​and the guide plate 55 to rotate forty-five degrees again and then stop running, so that the bottom end of the guide plate 55 no longer presses the top end of the first protrusion 391, and then the first protrusion 391 is reset by the elastic force of the first spring 395, driving the first baffle 394 and the second baffle 397 to move upward, so that the first baffle 394 and the second baffle 397 blocks the multiple first water inlet holes 393 and the fixing plate 396 again to preserve the seawater samples collected in the collecting cylinder 37. At this time, there is still residual seawater at the top of the positioning cover plate 51 and inside the installation cover plate 61. At this time, the multiple second one-way valves 48 are opened, allowing the remaining seawater to enter the first slot 41 through the multiple drainage pipes 47. After the second water level sensor 46 senses the water level information, it starts the water pump 43 to pump out the excess seawater in the first slot 41 through the water inlet pipe 42. At the same time, the first one-way valve 45 is opened, and the pumped seawater is discharged to the outside of the device through the outlet pipe 44. The first one-way valve 45 can prevent the discharged seawater from flowing back into the device. When the remaining seawater is discharged, the second water level sensor 46 no longer senses the water level information.The water pump 43 stops running, and then the multiple second one-way valves 48 and the first one-way valve 45 are closed. Then, the support mechanism 2 is reset, and the walking assembly 12 is driven again to move the device to the next designated sampling location. The device is then fixed horizontally again by the support mechanism 2, and the above steps are repeated, so that the multiple collection cylinders 37 can sample seawater at different locations.

[0052] When sampling seawater, the sixth motor 62 on the top side wall of the mounting cover 61 is turned on, and the sixth motor 62 starts to run, and its output end drives the fifth transmission shaft 63 to rotate, and the cleaning rod 64 fixedly connected to the outer side wall of the fifth transmission shaft 63 starts to rotate accordingly, and the multiple cleaning strips 65 arranged on the bottom side wall thereof will contact the top surface of the mounting cover 61 to clean the algae attached to the top of the mounting cover 61, and the rollers 67 connected to the bottom side walls of the connecting rods 66 at the bottom ends of both sides of the cleaning rod 64 rotate in the T-slot 68 opened at the top of the mounting cover 61, and the rolling of the rollers 67 can ensure the stability of the cleaning rod 64 during the rotation process. Qualitative, and can reduce the friction between the cleaning rod 64 and the installation cover 61, improve the cleaning efficiency, at the same time, start the first motor 13, drive the first transmission shaft 14 and the two arc rods 16 to rotate, and control the first electric telescopic rod 15 to extend and retract, so that the arc rod 16 rotates and moves back and forth, and start multiple sonars 17 to start running. The sonar 17 emits sound waves of a specific frequency and receives the reflected sound wave signals. According to the propagation time, reflection intensity and other information of the sound waves, it conducts detailed detection and analysis of the relevant geological structure of the stratum and submarine tunnel, the distribution of objects and the like, and can also drive away the fish.
