WAVE ROTOR-BASED MULTI-STAGE REFRIGERATOR

Номер: WO2019041869A1
Принадлежит:

A wave rotor-based multi-stage refrigerator mainly comprises a housing (20), a left end cap (19), a right end cap (25), a wave rotor (5), a central shaft (28), a high-pressure air feed nozzle, a medium-pressure air discharge nozzle, and a driving mechanism. The structure of the refrigerator enables a pressurized gas to undergo 2-8 non-steady expansions inside the refrigerator, thereby effectively increasing refrigeration efficiency at a large pressure ratio. In the refrigerator, extension of the structure thereof and a change in an end cap structure realize multiple expansions of a gas inside the refrigerator, thereby realizing multi-stage refrigeration by means of the expansions of the gas. Oscillation tubes provided at two ends of the refrigerator enable the refrigerator to operate normally when a moisture content in a working substance is high.

Rapid beach geological sample sampler

Номер: CN116183281A
Принадлежит:

The invention provides a rapid beach geological sample sampler which comprises a sleeve, a lifting and pressing structure, an adjusting structure, a clamping structure, a fixing structure, a sampling structure, an indicating structure and a supporting plate. The sampling structure can be driven to continuously move towards the ground or away from the ground through small-distance reciprocating motion of the lifting and pressing structure, so that sampling personnel can better apply force in the sampling process, and the sampling depth can be controlled by matching an adjusting structure with an identification structure; the clamping structure and the adjusting structure are not clamped by pushing the clamping structure, at the moment, the adjusting structure can be pushed to push out the sample from the interior of the sampling structure, so that the sample can be prevented from being adhered to the interior of the sampling structure, the sample can be conveniently taken out, and the sampling ...
