Centrifugal model test observation is highly to depend on to be arranged in a large amount of accurate testing tools in experimental cabin and the model casing.The temperature rise amplitude is to influence one of apparatus measures effect and the most important extraneous factor of precision in the experimental cabin.Therefore, the effect of experimental cabin cooling system is the accuracy that directly influences the centrifuge test result.
The geotechnical centrifuge experimental cabin type of cooling mainly contains air-cooled and water-cooled.Air cooling way is that cold wind is directly fed experimental cabin, takes away the experimental cabin heat, has increased the energy loss of equipment high speed rotating in this mode operational process, and exists near the bulkhead and the bigger temperature difference in experimental cabin center, and the air cooling effect has tangible limitation.Water-cooling pattern is considered at present the most effectively cooling means, in the minority super-magnum centrifuge, adopts.Its technical scheme has multiple; Known a kind of mode is in test bulkhead concrete, to arrange cooling water pipe; Because concrete heat transfer coefficient is less, the water pipe inside heat is delivered to through wall in the experimental cabin, its heat-transfer effect is also slower; During the hydro-extractor long-play, can't keep the needed temperature of experimental cabin.
Summary of the invention
In order to solve the problem and raising cooling effect that exists in the geotechnical centrifuge experimental cabin type of cooling, the purpose of the utility model is to provide a kind of spray water curtain style water cooling plant of geotechnical centrifuge experimental cabin.
The technical scheme that the utility model adopts is:
Comprise the ring cavity of forming by stainless steel top board, stainless steel outside plate, stainless steel base plate and stainless steel inner panel; The ring cavity outside is fixed on the experimental cabin reinforced concrete wall built-in fitting; Be furnished with annular spray steel pipe, stainless steel baffle upper plate and stainless steel chin spoiler under the stainless steel top board in the ring cavity successively with row's aperture; Be provided with many stainless steel floors between stainless steel baffle upper plate and stainless steel chin spoiler; Leave the gap between stainless steel baffle upper plate and stainless steel chin spoiler and the stainless steel inner panel, have water delivering orifice on the stainless steel base plate.
The center line and the horizontal line angle of the aperture on the described annular spray steel pipe are 45 °.
Described stainless steel baffle upper plate and stainless steel chin spoiler and horizontal line angle β are 45 °.
The beneficial effect that the utlity model has is:
The utility model adopts simple structure to form the cooling effectiveness that unique spray water curtain style water cooling mode has greatly improved the geotechnical centrifuge experimental cabin; The windage of hydro-extractor operation, the energy consumption of attenuating hydro-extractor operation have been reduced; The temperature homogeneity of experimental cabin can accurately be controlled the cooling of geotechnical centrifuge Laboratory Module when guaranteeing the hydro-extractor operation.This mode has characteristics such as efficient height simple in structure.The utility model has obtained practical application at the geotechnical centrifuge experimental cabin.
