Problems solved by technology

The most important thing is that the drilling rig can only be sampled at one position during a lowering process. If the drill sticks or the accident occurs after unloading, the sampling will only fail, which has high costs and high risks.
[0003] In fact, for the exploration of seabed resources, in addition to the large sampling depth, it is also necessary to sample the surface core at a small depth, such as the sampling of the surface layer of the seabed rock and mountain structure, which is difficult to achieve with the existing large drilling rig system

Embodiment 1

[0037] Such as Figure 1-2 As shown, Embodiment 1 of the present invention includes a feeding device 2 , a hydraulic motor I3 , a reduction box 4 , an impact rotating device 5 , a drilling tool receiving and unloading device 6 , a drilling tool storage device 10 and a drilling tool 12 . The feeding device 2 includes connecting plate I201, oil cylinder I202, piston rod I203, connecting plate II204, oil cylinder II205, piston rod II206, support plate 207, sliding sleeve 208, guide post 209, connecting plate III210 and insertion device 211. The upper surface of the connecting plate I 201 is connected with the manipulator 1 or clamped by the manipulator 1 . An oil cylinder I202 is fixed on the left and right sides of the bottom of the connecting plate I201, and the end of the piston rod I203 of the oil cylinder I202 is fixedly connected with the connecting plate II204. A guide post 209 is respectively fixed at four corners of the bottom of the connecting plate II 204 , and the lo...

Embodiment 2

[0052] Such as Figure 15 As shown, the structure of Embodiment 2 of the present invention is similar to that of Embodiment 1, the only difference is that: the feeding device 2 is eliminated, and the reduction box 4 is provided with a clamping rod 401 . When in use, the manipulator 1 directly clamps the clamping rod 401 provided on the reduction box 4 to perform sampling and drilling tool connection and unloading operations. It is applicable to the situation where the movement space range of the manipulator is large, and Embodiment 2 can reduce the number of hydraulic pipelines reserved for the deep submersible.

Abstract

The invention discloses a seabed multi-point-location percussion drilling coring miniature drilling rig carried by a submersible vehicle. The drilling rig comprises a first hydraulic motor, a gearbox,a percussion rotation device, a drilling tool connection and detachment device, a drilling tool storage device and drilling tools. The first hydraulic motor, the gearbox, the percussion rotation device and the drilling tool connection and detachment device transmit power in sequence. The power is transmitted to the drilling tools through the drilling tool connection and detachment device. The drilling tool connection and detachment device can select one drilling tool from the drilling tool storage device for connection and can detach the drilling tool which completes coring and enable the detached drilling tool to enter the drilling tool storage device. The seabed multi-point-location percussion drilling coring miniature drilling rig carried by the submersible vehicle is carried by the submersible vehicle, and can implement repeated multi-point-location coring and storage during one time of diving into the sea, and the economical efficiency of seabed operation is obviously improved; and the flexibility of seabed sampling operation is improved, and the drilling rig can be suitable for sampling seabed mountains and the seabed surface at the same time. During percussion drilling sampling with the seabed multi-point-location percussion drilling coring miniature drilling rig carried by the submersible vehicle, the efficiency and the effect of operation of hard rock coring are effectively improved, and meanwhile, the accident that a drilling bit gets stuck is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of seabed resource hard rock sampling, and in particular relates to a submersible multi-point percussion drilling micro-drilling machine for taking rock cores. Background technique [0002] The development of human society is inseparable from the development and utilization of various resources. Today, with the gradual depletion of land resources, people turn their attention to the deep ocean. There are extremely rich mineral resources in the seabed crust, including oil, natural gas, polymetallic nodules, cobalt-rich crusts, hydrothermal sulfides, marine organisms, gas hydrates, and clay minerals. These resources have great economic value and strategic importance. significance. The seabed core sampling drilling rig is the key technical equipment necessary for marine geological and environmental scientific research, marine mineral resource exploration and seabed engineering geological survey. As far as the...
