Document Type and Number:
WIPO Patent Application WO/2022/116387
Kind Code:
A1
Abstract:
A rainproof cap assembly, a pipeline assembly, and a turbine fracturing apparatus. The rainproof cap assembly (100) comprises at least two cover plate assemblies, wherein each cover plate assembly comprises a cover plate (1), a transmission mechanism (22), and a locking device (3). The cover plate (1) covers an opening when at a closed position; when the cover plate (1) of each cover plate assembly is at an opened position, the cover plate (1) forms an additional pipeline structure having both ends opened and extending in the extension direction of a pipeline. The cover plates (1) of the rainproof cap assembly (100) jointly form, when being opened, an additional pipe structure connected to an opening end of the pipeline, so as to guide the exhaust from the pipeline to a further space, such that noise can be reduced and backflow of the exhaust can be prevented. The cover plates (1) of the rainproof cap assembly (100) can cover, when being closed, the opening of the pipeline to prevent rain water from entering.
