Intensive culture pond bubble collector rotating at multiple degrees of freedom

The invention discloses an intensive culture pond bubble collector rotating at multiple degrees of freedom. A body structure consists of the five parts including a wrist plate, a connecting rod, a bubble discharging pipe, a main bubble collecting pipe and an auxiliary bubble collecting pipe which are fixed to the pond side, wherein the wrist plate and the connecting rod are connected through a deep groove ball bearing, the connecting rod and the auxiliary bubble collecting pipe are also connected through a sliding bearing, an inner meshing ratchet mechanism is installed between the main bubble collecting pipe and the auxiliary bubble collecting pipe, and a section of hose is installed in the middle of the bubble discharging pipe. The height is automatically adjusted through the effects of the bearings and the connecting rod, the self stress influence of an existing bubble collector is eliminated, an operator can turn the main bubble collecting pipe through the inner meshing ratchet mechanism so as to adjust t
