Abstract
A channel baffle structure comprises a pipe, a swing check plate and a driving apparatus, wherein the main part of the swing check plate is located inside the pipe, and the driving apparatus is disposed outside the pipe. A connection structure is used for connecting the driving apparatus and the swing check plate. The check plate can be opened and closed passively by gravity and fluid pressure, but can also be actively opened and closed by the driving apparatus, such that requirements for multiple operating conditions of the channel can be satisfied.

A channel baffle structure, comprising:
- a pipe;
- a swing check plate;
- and
- a driving apparatus;
- wherein the swing check plate comprises a tongue plate, a crank connecting rod and a rotating shaft, one end of the crank connecting rod being connected with the tongue plate using a nut, and the other end of the crank connecting rod being welded to a shaft sleeve of the rotating shaft;
- wherein a pipe wall of the pipe includes a circular opening for placing the tongue plate in a fully open state, a circular branch pipe being welded at the circular opening, an axis of the circular branch pipe being perpendicular to an axis of the pipe, an end of the circular branch pipe being in a form of a flange structure and connected with a pipe side cover plate by bolts;
- wherein the tongue plate, the crank connecting rod and a part of the rotating shaft of the swing check plate are arranged within the pipe, the driving apparatus disposed outside the pipe;
- wherein the swing check plate and the driving apparatus are connected through the rotating shaft, a bevel gear and a driving apparatus connecting shaft, one end of the rotating shaft being connected with the swing check plate, and the other end of the rotating shaft being connected with the bevel gear;
- one end of the driving apparatus connecting shaft being connected with the bevel gear, and the other end of the driving apparatus connecting shaft being connected with the driving apparatus;
- and
- wherein a structure for connecting the driving apparatus and the swing check plate comprises a key installed on the rotating shaft and connected with the crank connecting rod, an annular keyway correspondingly set within the shaft sleeve of the rotating shaft, such that the shaft sleeve has an idle travel of 90-degree free rotation around the rotating shaft, and the key is positioned within the annular keyway.
