Install mining equipment and gripper in corresponding mounting panel 505 top, it walks on the seabed to drive frame 1 through drive assembly 7, the frame 1 of crawling walks in-process of crawling, mining equipment starts the operation, the vibrations that produce in the mechanical equipment use are comparatively strong, realize the shock attenuation through damping spring rod 510, avoid the mounting panel 505 to appear connecting between the mining equipment and become flexible because of long-term vibrations, ensure that this mining equipment can normally run, simultaneously, after the vibrations are transmitted to transfer rod 509 department, it drives metal ball 508 and shakes, simultaneously move slider 512 certainly and slide in adjusting rail 502, thereby drive metal ball 508 and produce the swing of low margin, the condition that adjacent metal ball bumps can appear in the metal ball 508 swing in-process, the sound that metal ball 508 bumps produces further improves the acoustic wave and drives away the effect.
The operation of the crawling device is as follows.
Firstly, the position of the mounting plate 505 is adjusted, the adjusting hydraulic cylinder 511 drives the mounting plate 505 to reciprocate, and the mounting plate 505 presses the damping spring rod 510 in the moving process, so that the damping spring rod 510 is compressed to an optimal state. The mining equipment and the mechanical claws are arranged above the corresponding mounting plates 505, and the crawling frame 1 is driven to pass through the seabed by the driving assembly 7.
During the exploitation process, the mechanical claws guide the exploited natural gas hydrate into the storage tank 401, and after a large amount of natural gas hydrate is accumulated in the storage tank 401, the weight of the natural gas hydrate is increased. Under the force of gravity, storage bin 401 slides down angled slide rail 404 via gravity slider 414. At this time, the weight of the storage box and the natural gas hydrate in the storage box is used for limiting the gravity of the two sides of the crawling frame 1, so that the side turning of the crawling frame is effectively prevented.
As the bin 401 moves down, the arcuate rail 403 and the connecting slider 408 within the arcuate rail also move down. At the same time, the adjustment lever 405 drives the broadcaster 402 to slide in the chute of the arcuate guide rail 403. During the up-and-down movement of the broadcaster 402, the sound wave is transmitted to the ocean, and the sound wave expelling effect is achieved.
The crawling device suitable for exploiting the marine natural gas hydrate is described in detail above. The principles and embodiments of the present application have been described herein with reference to specific examples, the description of which is intended only to facilitate an understanding of the method of the present application and its core ideas.
