Description

Line box type complete tool for fixing fishing line and fixing method thereof

Technical Field

The invention relates to the field of cultural relic protection, in particular to a line box type complete tool for fixing a fishing line and a fixing method thereof.

Background

Museums are important places for collecting, researching, displaying and transmitting human cultural history and scientific and cultural knowledge, and are important bases for storing and maintaining cultural relics in museums. China is a large history culture country and numerous cultural relics. According to the data display of the first nationwide movable cultural relic census, as soon as 2016, 5, 18 and 14481 registered collection units in the nationwide movable cultural relic information registration platform log in 48592662 cultural relics (18413268 cultural relics/set). A large number of movable cultural relics are collected and stored in a museum, cultural relic display and daily maintenance management are facilitated, but the risk of large-scale damage of the cultural relics under sudden disasters is increased, and particularly, the natural disasters such as earthquakes which are seriously damaged are more and more, people feel more and more free and insufficient. Therefore, how to protect the cultural relics from being damaged in the earthquake and minimize the damage to the cultural relics caused by the earthquake should be the most important of the museum work.

In recent years, China frequently occurs earthquake, and a large number of cultural relics in the collection of the cultural relics are damaged. For example, 14 hours at 12 months and 12 days in 2008, 28 minutes and 04 seconds, 8.0-level Lishi earthquake occurs in Wenchuan and North China in Sichuan, which causes 2766 collected cultural relics in City of 7 provinces (city) such as Sichuan, Gansu, Shaanxi and the like to be damaged, wherein 292 precious cultural relics are included.

The cultural relics can adopt a certain method to resist the damage of the earthquake due to the strength, the rigidity or the flexibility of the cultural relics, thereby achieving the purpose of protection. The application of anti-seismic measures to cultural relics by foreign museums is common, and high-strength new materials are often generated in the anti-seismic protection of the museums in the United states, such as the American san Francisco Asia art museum, and each cultural relic displayed is fixed by a special metal bracket and other materials; cultural relics displayed in the Taibei Imperial palace are fixed by using a thin nylon wire in a precise measuring and calculating way; in the exhibition hall of the national museum of Kyoto Japan, part of the ceramics in the showcase are firmly fixed on the bottom support by transparent nylon wires, and the parts of the nylon wires, which are contacted with cultural relics, are sleeved with transparent plastic hoses; many units and expert scholars in China also carry out relevant research on earthquake-resistant measures of the exhibition-laid cultural relics, for example, in 1976, under the support of the national cultural relics office and earthquake-resistant offices in the Jingjin area of the national institute of construction and Commission of Japan at that time, 10 earthquake-resistant measures such as a gravity center descending method, a cementation method, a nylon hasp, a magnet method, an internal support method and the like are taken for 41 cultural relics of the Story museum, and tests are carried out on a vibration table, so that the cultural relics of the Story museum can be almost undamaged in the Tangshan earthquake of 1976.

The fish line ligature is one of the measures commonly used in museum historical relic exhibition, but the position of fish line ligature and the difference of ligature dynamics have directly influenced the effect of ligature, for example: the binding position is not proper, and the cultural relics cannot be guaranteed not to fall down; the cultural relics can be damaged by stress concentration under static force or dynamic force if the binding force is too large, and the protective effect cannot be achieved fundamentally if the binding force is not enough; moreover, ineffective banding may also create false images to the custodian, paralyze the mind during improper deployment, and cause damage to the cultural relics.

The application amount of using fish lines (nylon lines) to bind cultural relics in a museum to improve the shockproof safety and stability is huge, but the application amount only stays on the qualitative binding technical level based on experience, a complete technical guide is not formed, special equipment with simple operation and reliable technology is not provided, and a quantitative evaluation method for binding effect is not provided.
