Problems solved by technology

First of all, the existing test equipment does not consider the test environment for simulating the seabed rock water environment, and the error of the test environment will ignore the influence of seawater on the crushing performance of seabed rocks, which will not reflect the real situation of seabed rock crushing well, so it cannot be obtained. Accurate seabed rock crushing performance parameters reduce the reliability and accuracy of the rock crushing test device; secondly, the existing test device does not consider the problems of water inflow and seawater external resistance when testing the seabed rock, which affects the safety of the device sex, operability

Abstract

The invention discloses a testing device for smashing seafloor rock. The testing device comprises a spinning mechanism and a testing box body for simulating an environment of the seafloor rock, wherein fluid and rock to be tested are filled in the testing box body; the spinning mechanism comprises a spinning drilling head, a rotary driving assembly and a displacement driving assembly for driving the spinning drilling head to enter the testing box body for smashing the rock. The testing device for smashing the seafloor rock has the advantages of simple structure, simpleness and convenience in operation, high testing accuracy and high safety.

Description

technical field [0001] The invention relates to the technical field of underwater rock crushing, in particular to a test device suitable for seabed rock crushing. Background technique [0002] At present, land resources are gradually scarce, and humans are using and developing seabed resources more and more frequently, which makes the research on the crushing of seabed rocks the focus of resource development. The rocks in the seabed environment are very different from the land rocks, and the conditions of the two are different. The seabed rocks are covered by seawater, and water is an important factor affecting the rock breaking performance. [0003] The existing rock crushing test devices are mainly aimed at land rocks, and there are some deficiencies in the experimental research on rocks in the seabed environment. First of all, the existing test equipment does not consider the test environment for simulating the seabed rock water environment, and the error of the test env...
