Description

Be suitable for damping fire prevention treasure storage show cupboard

Technical Field

The utility model relates to a treasure storage show cupboard that is suitable for damping fire prevention belongs to the collection environment field of historical relics.

Background

China has huge cultural relics reserves in museums. According to statistics, about 51% of cultural relics in the collection of cultural relics in China have corrosion and mildew with different degrees, the loss caused by the corrosion and the mildew is difficult to estimate, and the storage environment needs to be improved urgently.

A microenvironment is an environment that can be well defined by location and a set of environmental metrics that can be measured. In the environment, each environment index can be described by adopting a uniform parameter. In terms of cultural relic protection, the cultural relic microenvironment refers to a storage space, such as a small closed space of a museum showcase, a storage sufferer and the like. Researches show that the cultural relics are very sensitive to environmental indexes such as temperature, relative humidity, illumination intensity, harmful gas concentration and the like in the microenvironment of the cultural relics, particularly the temperature and the relative humidity. Therefore, the preservation microenvironment for the cultural relics needs to be controlled.

The existing microenvironment maintaining system does not consider the influence of radiation temperature and air speed of an air conditioning system, only mainly measures the dry bulb temperature and relative humidity of the storage environment, and the temperature and the humidity are not the real temperature and humidity of the surface of the cultural relic and have great difference with the temperature and the humidity of the surface of the cultural relic, so that the control basis of the cultural relic storage environment has defects.

The concept of body temperature sensing is often used for measuring the comfort degree of a human body. The calculation formula of the body sensing temperature is as follows: tg is Ta + Tr + Tu-Tv, wherein Tg is somatosensory temperature; ta is the air temperature; tr is correction of body sensing temperature by radiation; tu is correction of the sensible temperature by humidity; tv is the correction of the sensible temperature by the wind speed. The detailed calculation method of the sensible temperature is shown in pages 165 of environmental meteorology and Special weather forecast (Wu Shu, Deng Xue Jia, Beijing: weather Press 2001). Similarly, in the field of cultural relic protection, only the dry bulb temperature and the wet bulb temperature of the cultural relic preservation environment are generally controlled at present, but not the real temperature and humidity of the surface of the cultural relic, and the air flow rate and the radiation temperature are not considered, but the air flow rate and the radiation temperature have great influence on the long-term intact preservation of the cultural relic, and the adverse influence on the preservation environment of the cultural relic can be avoided.

In addition, high-value cultural relic storehouses such as museum treasure storehouses and calligraphy and painting storage storehouses lack effective emergency safety guarantee measures when encountering earthquake and fire. Earthquake disasters have great harm to cultural relics and can cause direct damage to the cultural relics, and the prior art lacks effective means for seismic mitigation and isolation protection of the cultural relics. When a fire breaks out in a museum treasure house, although gas fire extinguishing equipment and the like can extinguish the fire in a short time, the heat radiation at the initial stage of the fire of the treasure house and a large amount of radiation heat emitted by a top plate, a floor and peripheral wall surfaces of the treasure house, which have greatly raised temperatures after the fire breaks out from the upper and lower parts of the treasure house and other common rooms at the periphery, can damage the surfaces of fragile cultural relics.
