基于专利数据挖掘的情报分析研究——以能源桩领域为例

Analysis of Patent Information Based on Data Mining

作为一种新型的建筑桩基和地源热泵的结合形式,建筑能源桩在可再生能源利用中日益受到重视。本文基于专利数据挖掘,从申请趋势、申请人国别、申请类别、审查结论、重要申请人等方面分析了建筑能源桩结构相关的专利申请,指出了相关技术由早期的桩基结构和材料、换热管的连接和排布、桩和管的连接逐渐向结构多样化、工艺精细化、桩管集成化发展,期望有助于创新主体获悉能源桩技术的申请现状和技术趋势,制订研究方向。

As a new form of combination of building foundation and ground source heat pump in renewable energy field,energy piles are gaining more attention in recent years.In this paper,based on the data mining of patent information,the patent applications of structures of energy piles are analyzed from the aspects of the filing trend,the applicant countries,the application types,the examination conclusions,the important applicants,etc.The paper indicates that the technologies are developing from the early interests on the structures and materials of piles,the connections and configurations of tubes,the connections between piles and tubes to the diversification on structures,the refinements of processes,the integrations of pile/tube,which would be helpful for the innovators to understand the application status and the technology trends,as well as to adjust research direction.
