[0026] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0027] Reference Figure 1-6 This utility model discloses a multifunctional geographic information mapping instrument, comprising a core compartment 1. The core compartment 1 has a streamlined structure, which effectively reduces fluid resistance during underwater movement and improves the stability and maneuverability of the equipment. The core compartment 1 is typically made of corrosion-resistant, high-strength materials (such as aluminum alloy or composite materials) and integrates a control unit, power module, and data processing system to coordinate the operation of various sensors and process the collected data in real time. A main multibeam echo sounder 6 is fixedly installed at the bottom of the core compartment 1 to perform the main water depth measurement tasks. Its multibeam characteristics can cover a wide scanning range, improving mapping efficiency. A connecting rod 7 is fixedly connected to the upper side of the core compartment 1, and the connecting rod 7 is mounted on an active stabilization platform or mapping vessel via a rotating base 2.

[0028] The core compartment 1 is equipped with a main multibeam echo sounder 6 at its bottom, which serves as the core for basic topographic mapping. Rigid robotic arms 4 are located on both the left and right sides. The outer end of the rigid robotic arm 4 is equipped with a standardized interface platform (such as a threaded interface or electrical slot) for quick installation and replacement of different types of sensors 5, such as side-scan sonar, magnetometer, water quality sensor, etc., to achieve multi-functionality. The rigid robotic arm 4 integrates a small electric cylinder and shock absorber, which can finely adjust the attitude and height of the end sensor 5 to compensate for hull sway or adapt to different installation positions. The end of the rigid robotic arm 4 near the core compartment 1 is equipped with a quick-release housing 3 and a rotating base 2.

[0029] A limiting post 21 is fixedly connected to the upper side of the rotating base 2, and a rotating groove 25 is provided on the outer side. A sealing ring 26 is installed in the rotating groove 25 to prevent water from entering the connection part. A limiting block 22 is fixedly connected to the outer side of the limiting post 21. A wire hole 24 is provided on the limiting post 21 located between the limiting blocks 22 for threading sensor cables to keep the wiring neat and avoid tangling. A limiting hole 23 is provided on the limiting block 22. The positioning rod 8 is adapted to the limiting hole 23 and is slidably connected to the limiting hole 23. The quick-release housing 3 is fixedly connected to the inner end of the rigid robotic arm 4.

[0030] The quick-release housing 3 has an annular groove 35 on its lower side, and a waterproof ring 36 is installed in the annular groove 35. The quick-release housing 3 has a guide groove 31 and a limiting groove 32 inside, and the guide groove 31 and the limiting groove 32 are connected. The guide groove 31 is used to guide the insertion of the limiting post 21 to ensure the rapid alignment of the rigid robotic arm 4 with the core compartment 1. The quick-release housing 3 located below the limiting groove 32 has a threaded hole 34, and the quick-release housing 3 on the upper side has a through hole 33. A positioning rod 8 is slidably connected to the upper side of the quick-release housing 3.

[0031] A sealing strip 81 is attached to the outer side of the upper end of the positioning rod 8, and a thread 82 is provided on the outer side of the lower end. A slotted swivel block 83 is fixedly connected to the top of the positioning rod 8 for easy manual rotation. The positioning rod 8 is slidably connected to the through hole 33 and is adapted to the through hole 33. The thread 82 on the positioning rod 8 is adapted to the threaded hole 34.

[0032] Different rigid robotic arms 4 can be quickly switched when performing different tasks: for example: basic terrain tasks: core module 1 (main multibeam) + single rigid robotic arm 4 (side scan sonar); comprehensive geological survey: core module 1 + single rigid robotic arm 4 (shallow seismic profiler) + single rigid robotic arm 4 (magnetometer); underwater target search: core module 1 + two task arms (high frequency side scan sonar + underwater camera / lighting system).

[0033] Working principle: In use, firstly, the rigid robotic arm 4 is connected to the rotating base 2 on the side of the core compartment 1 via the quick-release housing 3. The operator aligns the guide groove 31 of the quick-release housing 3 with the limiting post 21 of the rotating base 2, and slides it downward along the guide groove 31, allowing the limiting post 21 to enter the limiting groove 32. At this time, the limiting hole 23 on the limiting block 22 is aligned with the through hole 33 on the quick-release housing 3. Then, the positioning rod 8 is inserted from above the through hole 33, passing through the limiting hole 23, and the slotted block 83 is rotated, so that the thread 82 at the lower end of the positioning rod 8 engages with the threaded hole 34. As the positioning rod 8 is screwed in, its lower end gradually presses against the limiting block 22, thereby firmly locking the quick-release housing 3 and the rotating base 2. The sealing strip 81 and the waterproof ring 36 ensure the waterproof performance of the connection. The entire process requires no tools, realizing the quick assembly and disassembly of the rigid robotic arm 4, which is convenient for transportation and maintenance.

[0034] During mapping, the main multibeam echo sounder 6 continuously scans the seabed topography, generating high-resolution water depth data. Simultaneously, sensors 5 on the rigid robotic arm 4 collect auxiliary data, such as seabed images, magnetic field strength, or water quality parameters. All data is transmitted via cables within the cable port 24 to the control unit in the core module 1 for real-time fusion processing. The streamlined design of the core module 1 reduces water flow disturbance and improves data quality. The equipment can be mounted on ships or AUVs (autonomous underwater vehicles) to achieve large-scale, multi-parameter geographic information mapping.

[0035] When performing different surveying tasks, different rigid robotic arms 4 can be quickly replaced to replace the sensor 5 without the need for tools.

[0036] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
