Description
Technical field
The present invention relates to a kind of ecological flow metering-orifice import dome-type one piece casting type trash racks, belong to hydraulic and hydroelectric engineering gold
Belong to technical field of structures.
Background technology
It is needed based on environmental protection, hydraulic and hydroelectric engineering usually sets ecological flow metering-orifice in dam body bottom, in ecological flow metering-orifice
Drain valve bleed downstream ecological flow is set, considers that the larger dirt of dam body bottom size can cause valve body to damage into air stream enter runner
It is bad, sluicing runner can even be caused to block sometimes and trigger engineering accident, therefore, generally set in the import of ecological flow metering-orifice fixed
Trash rack, and traditional trash rack uses welding structure, grid only leans on the weld seam with fence frame contact site to fix, and is flowing
It is used in the excessively high ecological flow metering-orifice of speed, grid easily snaps off, and larger dirt is caused to enter ecological flow metering-orifice, is only suitable for low
Flow velocity occasion, so the prior art or incomplete, up for further improving.
The content of the invention
It is an object of the present invention to provide a kind of ecological flow metering-orifice import dome-type one piece casting type trash rack, to improve
Trash rack overall structure rigidity and intensity, and meet the trash rack body construction strength and stability requirement in the case of flow velocity height,
So as to overcome the deficiencies in the prior art.
The technical proposal of the invention is realized in this way：
A kind of ecological flow metering-orifice import dome-type one piece casting type trash rack of the present invention, it is different in ecological flow metering-orifice including being located at
Footpath is managed or equal pipe, and the water inlet of reduced pipe and equal pipe is welded with annular steel plate, and annular steel plate is equipped with and is uniformly distributed along the circumference
Double shackle, double shackle is connected through bolt with dome-type one piece casting type trash rack；Dome-type one piece casting type trash rack is whole
Body structure, including wooden club core barrel, wooden club core barrel is uniformly distributed on peripheries with the fan-shaped floor of radial arrangement, and fan-shaped rib edges edge is set
There is bolt hole, annular plate of the fan-shaped floor through one group of different-diameter connects.
In foregoing dome-type one piece casting type trash rack, junction and fan of the wooden club core barrel with fan-shaped floor
The junction of shape floor and annular plate is arc transition connection.
In foregoing dome-type one piece casting type trash rack, the dome-type one piece casting type trash rack downstream face is plane,
The global shape of upstream face is streamlined hemisphere face.
In foregoing dome-type one piece casting type trash rack, the wooden club core barrel upstream end diameter is more than downstream diameter,
Downstream is streamlined sphere structure.
By adopting the above-described technical solution, compared with prior art, the present invention trash rack of the present invention uses monoblock cast
Lattice dome-type, be simple to manufacture, grid body entirety uniform force, stress concentration caused by welding, trash rack overall structure
Rigidity is big, intensity is high, meets the trash rack body construction strength and stability requirement in the case of flow velocity height, and dirt is not easy to adhere to
On trash rack, be conducive to block dirt；Grid body flow-passing surface be dome-type, wooden club core barrel front/rear end be streamline construction, fan rib
Plate and circumferential rib upstream face are circular arc streamline construction, greatly reduce current damping, HYDRODYNAMIC CONDITION RELATING TO is good, effectively reduces and blocks dirt
The vibration of grid；Using the small reduced pipe in the big rear end in front end and equal pipe connection mode after annular steel plate, pass through local increase ecology
Metering orifice flow-passing surface can reduce flow velocity, advantageously reduce the vibration of trash rack, be conducive to the high ecological flow metering-orifice of flow velocity and block dirt.
