The invention discloses an upward pushing and pressing expansion type in-
barrel cleaning device and relates to a cleaning device for pure water barrels, in particular to a two-way upward pushing and pressing expansion type in-
barrel cleaning device which can shrink automatically in the presence of power and is used for solving the problems that existing pure water factories in various scales in China have no ideal in-
barrel cleaning devices, some cleaning devices can only clean a small part of
dirt in the barrels, particularly, the water barrels are large, barrel mouths are small, and larger cleaning tools can not enter into the barrels for cleaning in the background art. The technical scheme for solving the technical problems is as follows: the upward pushing and pressing expansion type in-barrel cleaning device mainly comprises a connecting platform, a friction plate, a positioning shaft, a
clutch friction plate, a spring, a driving shaft, a
thrust bearing, a rotating sleeve, a cylinder, a
water pipe, a connecting frame, a driving wheel, a guide shaft, a motor and the like, the device is simple, time-saving and labor-saving to operate, the device can be used alone, a plurality of the devices can also be used simultaneously according to needs, the device can be equipped onto other filling devices, and the inside and the outside can be simultaneously cleaned without leaving dead angles.
