Device for monitoring grotto temple air flow field flow velocity dynamic state by utilizing smoke particle motion trail

Abstract

The invention relates to a device for monitoring the grotto temple air flow field flow velocity dynamic state by utilizing a smoke particle motion trail. The device is structurally characterized in that: an air blower, a pulse pump distributed with a smoke generating pipe and an LED (Light Emitting Diode) plate lamp are arranged in a grotto temple, a pulse pump pipeline is connected with a pulse timing switch, a computer is connected with a storage card, and the storage card is placed in a camera box, a camera is sleeved with an annular LED lamp and supported by a support to stand in the grotto temple; a coordinatometer and a fuming timer are arranged in the grotto temple, a wind direction sensor and a wind speed sensor are arranged along the trend of the grotto temple building and are connected with a data acquisition instrument, and a computer and a mobile phone transmit data to each other. By monitoring the influence of different wind speeds in the grotto temple on the smoke particle motion trail in closed and semi-closed environments, the flow velocity dynamic characteristics of the grotto temple air flow field in different environments are judged. The device is simple in structure, high in practicability and low in cost, is widely applied to research on dynamic characteristics of the air flow field flow velocity in the grotto temple in different environments, and plays a certain role in protecting ancient cultural heritage.

Description

technical field [0001] The invention relates to a monitoring device for smoke particles under the dynamic flow velocity of the air flow field of a grotto temple. Background technique [0002] Cave temples are one of the oldest forms of Buddhist architecture. The most famous Buddhist caves in India are the Ajanta Caves built from the 1st and 2nd centuries BC to the 5th century AD. artistic value. From the 4th century to the 8th century AD, the architectural art of Indian Buddhism spread to the east. Northwest my country, such as Kuqa in Xinjiang, Dunhuang in Gansu, Yungang in Shanxi, Longmen in Henan, South and North Xiangtang Mountains in Hebei, etc. The existing ancient grottoes are all built by absorbing the plastic arts of Indian grottoes. Grottoes were originally the residences of Buddhist monks. There are two common forms, one is called "Worship Cave" and the other is called "Zen Cave". Buddha statues are carved in the worship cave for people to pay respect to and wor...

Problems solved by technology

The sand-carrying airflow entering the grotto cave not only causes serious abrasion to the surface of cultural relics such as murals and painted sculptures, but also accelerates the occurrence of diseases such as peeling and shedding of the pigment layer; rainfall causes the outdoor humidity to increase, and due to the indoor and outdoor air exchange, the outdoor environment High humidity infiltrates into the room, causing diseases such as brittle alkali on murals; artificial disturbances such as tourists visiting and staff maintenance, and smoke generated by pilgrims burning incense will change the indoor air flow field and pose a potential threat to the intact preservation of murals
