[0002] Worldwide, about 90% of the ocean continental slope area contains favorable conditions for the formation of natural gas hydrates, which is a unique mineral resource occupying a pivotal economic position in seabed resources. However, in the pursuit of its huge economic value, the occurrence characteristics of natural gas hydrates and the maturity of exploration and exploitation technology are directly related to the ecological and environmental risks that may be triggered. These risks include but are not limited to the instability of seabed geological structure, the further deterioration of global greenhouse effect, and the irreversible damage to marine ecosystems. Therefore, in order to ensure that the development and utilization of natural gas hydrates are both efficient and safe, while taking into account the sustainability of environmental protection, it is particularly important to build a scientific and rigorous, accurate and comprehensive, and real-time feedback environmental and geological monitoring system.

[0037] The working principle of the application is as follows:

[0038] The third body section of the submarine stratum space drilling robot provided by the application is provided with a battery cabin 5-2, which supplies power to the whole robot. The second walking body section 1-3 is provided with a drive motor control cabin 3-7, which is responsible for the driving and central control of all motors, including the path planning and following control of the robot. When the robot is working, the first drill bit drive motor 2-7 is started. Since the output shaft of the first drill bit drive motor 2-7 is fixedly connected with the first drill tip 2-1 through a connecting ring, the drill bit of the first body section 1-1 can rotate. Similarly, the second drill bit drive motor 5-5 is started. Since the output shaft of the second drill bit drive motor 5-5 is fixedly connected with the second drill tip 5-6 through a connecting ring, the drill bit of the third body section 1-5 can rotate, thereby realizing the drilling function of the first body section 1-1 and the third body section 1-5. The drive motor 3-4 is started. Since the output shaft of the drive motor 3-4 is fixedly connected with the first gear 4-1, the first gear 4-1 rotates and drives the second gear 4-3 to rotate, and the second gear 4-3 drives the gear ring 4-4 to rotate. Since the counter-rotational helical blade 3-5 is fixedly connected with the outside of the gear ring 4-4, the counter-rotational helical blade 3-5 of the second walking body section 1-3 realizes the rotating function. The drive servos 6-3 of the front drive body section 1-2 and the rear drive body section 1-4 are respectively started. Since the output shafts on both sides of one end of the drive servo 6-3 are fixedly connected with the large U-shaped frame 6-1, and the other end is fixedly connected with the small U-shaped frame 6-4, and the first body section 1-1 and the front drive body section 1-2, the second walking body section 1-3 and the rear drive body section 1-4 are all connected through the large U-shaped frame 6-1, and the front drive body section 1-2 and the second walking body section 1-3, the rear drive body section 1-4 and the third body section 1-5 are all connected through the small U-shaped frame 6-4, the drive motor 3-4 of the front drive body section 1-2 drives the first body section 1-1 to swing up and down by a certain angle, that is, the drill bit of the first body section 1-1 can swing up and down by a certain angle when performing the drilling work, and the drive motor 3-4 of the rear drive body section 1-4 drives the second walking body section 1-2 to swing up and down by a certain angle, thereby realizing the two-dimensional plane steering function of the first body section 1-1, the second walking body section 1-3 and the third body section 1-5, and making the robot perform the drilling work by peristalsis. Through the regulation and control of the drive motor control cabin 3-7 in the second body section 1-2, when the first body section 1-1 rotates clockwise under the drive of the first drill bit drive motor 2-7, the third body section 1-5 also rotates clockwise under the drive of the second drill bit drive motor 5-5, and the second walking body section 1-3 rotates counterclockwise under the drive of the drive motor 3-4, the robot drills forward. When the first body section 1-1, the second walking body section 1-3 and the third body section 1-5 all rotate in the opposite direction of forward movement, the robot drills backward, thereby realizing the flexible and free drilling of the robot in the stratum. The sensor information acquisition cabin 2-4 in the first body section 1-1 is provided with a pH sensor 2-5, a temperature sensor 2-8 and a methane concentration sensor 2-6, which can collect the values of pH, temperature and methane concentration during the drilling process.
