Spray water curtain-type cooling device of geotechnical centrifuge test cabin

Abstract

The invention discloses a spray water curtain-type cooling device of a geotechnical centrifuge test cabin. The spray water curtain-type cooling device of a geotechnical centrifuge test cabin comprises a stainless steel top plate, a stainless steel outer plate, a stainless steel base plate and a stainless steel inner plate and forms an annular cavity. An outer side of the annular cavity is fixed on embedded parts of a reinforced concrete wall of a geotechnical centrifuge test cabin. An annular spray steel pipe with a row of apertures, a stainless steel upper guide plate and a stainless steel lower guide plate are orderly arranged below the stainless steel top plate in the annular cavity. The stainless steel upper guide plate and the stainless steel lower guide plate have gaps with the stainless steel inner plate. The stainless steel base plate is provided with a water outlet. The spray water curtain-type cooling device of a geotechnical centrifuge test cabin has the advantages that 1, through a spray water curtain-type cooling method, cooling efficiency of the geotechnical centrifuge test cabin is improved; centrifuge running wind resistance is reduced; centrifuge running energy consumption is reduced; temperature homogeneity of the geotechnical centrifuge test cabin in centrifuge running is guaranteed; and cooling of the geotechnical centrifuge test cabin can be controlled accurately; and 2, the spray water curtain-type cooling device has a simple structure and high efficiency and can be utilized for a geotechnical centrifuge test cabin.

Description

technical field [0001] The invention relates to a cooling device for a test chamber of a geotechnical centrifuge, in particular to a spray water curtain type water cooling device for a test chamber of a geotechnical centrifuge. Background technique [0002] Geotechnical centrifugal simulation test technology is a new test technology, which is characterized by the use of high-speed rotating equipment to generate a centrifugal force field, so that the model soil has the same self-weight stress as the prototype, and the deformation and failure mechanism of the model is similar to the prototype. So as to solve the corresponding geotechnical engineering problems. This simulation technology has been widely used in the basic theoretical research of rock and soil mechanics, successfully solved various important issues such as the disaster mechanism of large-scale infrastructure, and played an important role in the fields of water conservancy, transportation, energy, aviation, life s...

AI Technical Summary

Problems solved by technology

There are many technical solutions, one known method is to arrange cooling water pipes in the concrete of the test bulkhead, because the heat transfer coefficient of concrete is small, the heat in the test cabin is transferred to the water pipes inside through the wall, and the heat transfer effect It is also slow, and when the centrifuge runs for a long time, it cannot maintain the temperature required by the test chamber
