WIPO Patent Application WO/2022/036871
Kind Code:
A1
Abstract:
Disclosed is an all-round no-dead-corner sewage suction truck. A movable platform is installed on the rear portion of a truck frame in a swinging manner; a sewage suction pipe is movably installed on the movable platform, and an end of the sewage suction pipe is connected to a pumping structure by means of a corrugated hose; a driving assembly is installed on the rear portion of a storage container; and the driving assembly is respectively connected to the pumping structure and the movable platform. After sewage suction work is completed, the sewage suction pipe is swung and retracted by means of an accommodation assembly, such that the sewage suction pipe is folded and fixed on one side of the storage container, thereby facilitating transportation by the sewage suction truck. When the sewage suction work is carried out, the driving assembly is used for respectively driving the pumping structure and the movable platform to move, wherein the movable platform drives the sewage suction pipe to swing back and forth under the action of the driving assembly, thereby expanding the sewage suction range and realizing no-dead-corner sewage suction; moreover, the driving assembly also drives the pumping structure to pump sewage into the storage container by means of the sewage suction pipe.
