Abstract

The invention relates to a pneumatic hammer device and particularly relates to a pneumatic reciprocating tamping device in deep sea, which is suitable for sampling overlong columnar sediments under a deep sea environment. The pneumatic reciprocating tamping device comprises a deep water motor, a deep water pressure tank, and a hammer head, a half nut, a taper pin, a compression cylinder, a lead screw, a spring and a mandril, which are installed in the deep water pressure tank, wherein one end of the lead screw is connected with the output end of the deep water motor, the hammer head is sleeved on the other end of the lead screw, the half nut is located in the hammer head, the spring used for connecting the half nut with the lead screw through threads is connected on the half nut, and the compression cylinder sleeved at the outside of the lead screw is arranged between the upper surface of the hammer head and the bottom surface of the upper end cover of the deep water pressure tank; the mandril is inserted on the hammer head, and the taper pin used for opening the half nut is arranged on the mandril. The pneumatic reciprocating tamping device provided by the invention can be used for enabling a sampling system to repeatedly penetrate deep sea sediments for multiple times, so that the sampling length of the current gravity type deep sea sediment sampling system can be increased greatly, and the sampling length is as long as 20-30 meters to facilitate the condition that scientists can obtain overlong deep sea sediment samples.

Description

technical field [0001] The invention relates to an air hammer device, in particular to a deep-sea pneumatic reciprocating ramming device, which is suitable for sampling ultra-long columnar sediments in a deep-sea environment. Background technique [0002] Deep-sea columnar sediment samples are used in global climate and environmental change research, marine sedimentology research, carbon cycle and its structure-climate linkage research, marine geological census, seabed mineral resource exploration, microbial life process in deep sea strata and its geological significance, ancient Oceanographic research, research on the mineralization mechanism and distribution of deep-sea hydrothermal products, deep-sea marine engineering geological survey, military oceanography and many other research fields are of great significance. The common deep-sea sediment sampling method is mainly the gravity sampling system. The operation method is to use the survey ship to sink the sampler into th...
