Further, the bottom section of described cylindrical shell is inverted trapezoidal, and submersible pump is supported on coupling seats, and coupling seats is supported on the bottom of inverted trapezoidal structure.
Further, described water inlet pipe internal orifice arranges knife gate valve.
Further, establish corresponding containing in described cylindrical shell and be articulated in the dirty net in hurdle below inspection platform.
Further, establish crush type basket grid in described hurdle dirt net, crush type basket grid be that jacking condition is connected on the grid guide rail that is vertically arranged in cylindrical shell, and grid guide rail correspondence anti-slip top covers grid lifting eye.
Further, trapezoid structure barrel is provided with outside the inverted trapezoidal barrel of described cylinder body bottom.
Further, the outlet pipe in described cylindrical shell is provided with flap valve and hand sluice valve.
Further, described coupling seats or submersible pump are that jacking condition is connected on the pump guide rail that is vertically arranged in cylindrical shell, and the corresponding anti-slip top of pump guide rail covers water pump lifting eye.
Further, the liquid-level floater of multiple differing heights is linked with below described inspection platform.
Again further, the outer mouth of pipe of described water inlet pipe and outlet pipe is equipped with flexible joint.
Adopt above technical scheme, the beneficial effects of the utility model are: the bottom of cylindrical shell comprises inverted trapezoidal structure inwall and trapezoid structure outer wall, inverted trapezoidal structure is without bottom right angle dead angle, cannot silting, when water body sends into cylinder body bottom, can effectively send through submersible pump, non sludge deposits, and clears up without the need to mud; The outer wall energy stable support cylindrical shell of trapezoid structure, avoids the support of inverted trapezoidal structure inwall unstable, guarantees pumping plant use safety.Non sludge deposition in pumping plant, during Long-Time Service or after not using for a long time, without biogas in cylindrical shell, maintenance safety in maintainer's lower shell.
