Experimental apparatus for sunlight projection simulation

Abstract

The invention discloses an experimental apparatus for sunlight projection simulation. The experimental apparatus comprises a case, an equatorial plane plate, a time dial disc and a ground plane plate. The angle of the equatorial plane plate can be adjusted correspondingly according to seasons, and the angle of the ground plane plate can be adjusted automatically according to geographic latitudes. The time dial disc can rotate freely by 360 degrees. Through placement of a building model on the ground plane plate and combination of irradiation of a spotlight source, various sunlight projection conditions under comprehensive influences of multiple factors can be accurately and visually simulated. The experimental apparatus can simulate static or dynamic projection conditions of buildings at different longitudes and latitudes, time, declination angles and sun altitudes, and has the advantages of compact structure, high automation degree, high accuracy, high visual effect and the like, thereby being of great significance in architectural design and urban planning and design and being particularly applicable to sunlight projection simulation and the like during architectural design or architecture teaching.

Description

technical field [0001] The invention belongs to the technical field of architectural design and planning, and more specifically relates to an experimental device for simulation of sunlight projection. Background technique [0002] Architectural sunshine is an issue that must be considered in architectural design. For example, the time and range of sunshine play a vital role in determining the distance between buildings and the arrangement of building orientations. In some cases, buildings need to avoid sunlight, such as preventing indoor overheating in summer or indoor spaces that are required to avoid glare or exposure; It can make the room get more solar radiation in winter, thereby increasing the indoor temperature, etc.; in addition, buildings in cold regions generally need to strive for better sunshine, and most buildings in mild regions also need to have a certain amount of sunshine time at least around noon in winter At this time, the sunlight contains more ultraviol...

Problems solved by technology

[0004] However, further studies have shown that the above-mentioned existing sunshine projection simulation devices still have the following defects or deficiencies: First, they are difficult to fully simulate the static or Due to the dynamic projection situation, there are problems of limited application occasions and incomplete functions; secondly, due to the need for manual control, while putting forward higher requirements for the operator, it also brings corresponding defects such as low simulation accuracy and low operation efficiency; Third, for many occasions, such as classroom demonstrations for students in the process of architectural teaching, or miniature architectural model tests in the process of old city renovation and architectural design, it is often necessary to facilitate quick switching and more intuitive simulations effect, and the existing technology is difficult to meet the requirements of this aspect
