Abstract

The present disclosure provides a rain shield assembly, a pipe assembly and a turbine fracturing unit. The rain shield assembly comprises at least two sets of cover plate assemblies, wherein each set of cover plate assembly comprises a cover plate, a transmission mechanism and a locking device. When the cover plate(s) is(are) at a closed position, the opening is covered; when the cover plate of each set of cover plate assembly is at an open position, an additional pipe structure which is open at both ends and extends along an extension direction of the pipe is formed by which. According to the present disclosure, the cover plate(s) of the rain shield assembly, when opened, will jointly form an additional pipe structure connected to the open end of the pipe to guide the exhaust gas of the pipe to a further space. Such an arrangement may reduce noise on the one hand, and prevent backflow of the exhaust gas on the other hand. The cover plate(s) of the rain shield assembly, when closed, can shield the opening of the pipe to prevent entry of rainwater.
