The purpose of the utility model is to provide a kind of ecological flow metering-orifice import pyramid type one piece casting type trash rack, with
Trash rack overall structure stiffness and strength are improved, to meet the trash rack body construction strength and stability in the high situation of flow velocity
It is required that and overcome the deficiencies in the prior art.
The technical solution of the utility model is achieved in that
A kind of ecological flow metering-orifice import pyramid type one piece casting type trash rack of the utility model, including it is located at ecological flow
The water inlet of reduced pipe or equal pipe in hole, reduced pipe and equal pipe is welded with cyclic annular steel plate, and cyclic annular steel plate is equipped with edge
The double shackle of circumference uniform distribution, double shackle are connect through bolt with pyramid type one piece casting type trash rack；Pyramid type one piece casting type blocks
Dirty grid are overall structure, including mandrel, mandrel are uniformly distributed on peripheries with the triangle floor of radial arrangement, and triangular fin edges of boards edge is set
There is bolt hole, triangle floor is connected through the annular plate of one group of different-diameter.
In aforementioned pyramid type one piece casting type trash rack, the junction and triangle of the mandrel and triangle floor
The junction of floor and annular plate is arc transition connection.
In aforementioned pyramid type one piece casting type trash rack, the pyramid type one piece casting type trash rack downstream face is plane,
The global shape of upstream face is streamlined circular conical surface.
In aforementioned pyramid type one piece casting type trash rack, mandrel upstream end diameter is greater than downstream diameter, downstream
For streamlined sphere structure.
By adopting the above-described technical solution, the utility model is compared with prior art, the utility model trash rack is used
The lattice pyramid type of monoblock cast, is simple to manufacture, grid body entirety uniform force, and stress caused by welding is concentrated, trash rack
Overall structure rigidity is big, intensity is high, meets the trash rack body construction strength and stability requirement in the high situation of flow velocity, and dirt
It is not easy to be attached on trash rack, is conducive to block dirt；Grid body flow-passing surface is pyramid type, and mandrel front/rear end is streamline construction, triangle
Shape floor and circumferential rib upstream face are circular arc streamline construction, greatly reduce water flow damping, HYDRODYNAMIC CONDITION RELATING TO is good, effectively reduces
The vibration of trash rack；Using the small reduced pipe in the big rear end in front end and equal pipe connection type after cyclic annular steel plate, pass through local increase
Ecological flow 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
It is dirty.
