Building model indoor natural ventilation testing device

Abstract

The invention discloses a building model indoor natural ventilation testing device. The building model indoor natural ventilation testing device comprises a bottom supporting mechanism, a lifting adjusting mechanism and a natural ventilation testing mechanism; the bottom supporting mechanism comprises a base and three universal wheels, the base is horizontally arranged, and the three universal wheels are fixedly installed at the bottom of the base; the lifting adjusting mechanism comprises a supporting column and a supporting rod, the supporting column is vertically and fixedly installed at the center position of the upper part of the base, the interior of the supporting column is of a hollow structure, the supporting rod is vertically and movably installed in the supporting column, and the upper end of the supporting rod extends out of the exterior of the upper end of the supporting column. According to the building model indoor natural ventilation testing device, the moving is relatively convenient, using is convenient, the heights can be adjusted, the air speed of the positions of indoor different heights of a building model can be tested, the ventilation condition of indoor different positions of the building model can be relatively comprehensively tested, the air speed of the indoor slant direction of the building model can be tested, and a testing result is more scientific and reasonable.

Description

technical field [0001] The invention relates to the technical field of construction, and more particularly, to a natural ventilation test device in a building model room. Background technique [0002] Natural ventilation is an important concept of ecological architecture. On the one hand, natural ventilation in the building can improve the indoor thermal environment in summer or transitional seasons, take away moist and dirty air, and accelerate the volatilization of skin sweat on the surface of the human body, thereby improving the comfort of the human body; On the one hand, natural ventilation can provide fresh and clean natural air without consuming non-renewable energy, which is conducive to saving energy and protecting the environment. Natural ventilation in the architectural sense refers to the flow of air under the action of wind and thermal pressure through purposeful openings. [0003] When designing and constructing a house, we usually design a house building mode...

AI Technical Summary

Problems solved by technology

[0004] The indoor natural ventilation test device of the architectural model in the prior art needs to be manually lifted and moved when moving, which makes it inconvenient to move and cause inconvenience in use; secondly, the natural ventilation test device in the architectural model room of the prior art, its height Generally, it cannot be adjusted, so that it cannot test the wind speed at different heights in the building model room, so that it cannot comprehensively test the ventilation conditions at different positions in the building model room; in addition, the natural ventilation test device in the building model room in the prior art , it cannot be tilted and adjusted, which makes it impossible to test the wind speed in the oblique direction in the building model room, which leads to unscientific and reasonable test results
