Abstract
The utility model provides a streamline anti-drag trash rack and belongs to the technical field of environment engineering. A streamline gradually-reduced door frame made of a steel and iron material, a streamline cross beam and a streamline grid bar are fixedly arranged to form a steel frame structure, so that the purposes of rinsing, trash holding and resistance reducing are achieved; the streamline gradually-reduced door frame is vertically and horizontally symmetrical, and the cross-section of a river is gradually reduced along the water flow direction; the cross section of the streamline cross beam in the water flow direction is of a streamline form with two sharp ends and a large middle; the streamline cross beam is fixed on the streamline gradually-reduced door frame by virtue of welding; streamline holes are uniformly distributed in a direction vertical to the water flow direction; the cross section of the streamline grid bar in the water flow direction is of a streamline form with two sharp ends and a large middle; the cross section of the streamline grid bar is matched with the streamline holes in the streamline cross beam; the streamline grid bar passes through the streamline holes in the streamline cross beam; two ends of the streamline grid bar are fixed on the streamline gradually-reduced door frame by virtue of welding. The streamline anti-drag trash rack is used for trash holding at the inlet of a water intake structure, is capable of achieving the purposes of rinsing, trash holding and resistance reducing, and can be used for reducing hung floaters, facilitating decontamination of the trash rack, greatly reducing the resistance to waterflow which passes through the trash rack, effectively improving the discharge capacity of the trash rack, reducing the energy consumption and lowering the water conveying cost.
Description
Technical field
The utility model relates to trashrack structural shape, belongs to water conservancy field of environment engineering technology.
Background technology
China's pollution of river is serious at present, and a large amount of water plants of the water surface and floating thing are stacked into intake structure import with current, hinders current, causes hydraulic loss, reduces conveyance power of water.Existing trashrack is mostly i iron, angle steel and Plate Welding, and section is rectangle, easily climbs extension floating thing, blocks water serious, causes larger hydraulic loss, reduces emptying effectiveness.
Utility model content
The purpose of this utility model is easily to climb extension floating thing for existing trashrack, block water serious, cause larger hydraulic loss, reduce emptying effectiveness problem, design a kind of streamlined drag reduction formula trashrack, realize the function of blocking dirty and drag reduction, can significantly reduce grid resistance to water-flow, effectively improve trashrack discharge capacity, reduce energy consumption and water delivery cost.
The purpose of this utility model is to realize like this, a kind of streamlined drag reduction formula trashrack, it is characterized in that, be provided with streamline gradual shrinkage doorframe, streamlined crossbeam and streamlined grizzly bar that ferrous materials is made, streamlined crossbeam and streamlined grizzly bar are fixedly mounted on streamline gradual shrinkage doorframe, form a steel frame construction, the object that reached water, blocks dirt and drag reduction.
Described streamline gradual shrinkage doorframe, upper and lower, left and right symmetry respectively, the cross-section of river dwindles gradually along water (flow) direction.
Described streamlined crossbeam, cross section is two ends point along water (flow) direction, broad in the middle is streamlined, is fixed by welding on streamline gradual shrinkage doorframe uniform streamlined hole on Transverse to the flow direction.
Described streamlined grizzly bar, cross section is two ends point along water (flow) direction, and broad in the middle is streamlined, and mate with the streamlined hole on streamlined crossbeam in the cross section of streamlined grizzly bar, streamlined grizzly bar is through the streamlined hole on the streamlined crossbeam of stream, and two ends are weldingly fixed on streamline gradual shrinkage doorframe.
The utility model is rational in infrastructure simple, is made up of streamline gradual shrinkage doorframe, streamlined crossbeam and streamlined grizzly bar, blocks dirt, the object that reached water, blocks dirt and drag reduction for intake structure import.Adopt streamline gradual shrinkage doorframe, the cross-section of river is expanded gradually along water (flow) direction, improve the discharge capacity of trashrack, streamlined crossbeam and streamlined grizzly bar, can improve discharge capacity, can reduce and climb extension floating thing again, facilitates removing contamination of trashrack.Streamlined drag reduction formula trashrack, can significantly reduce grid resistance to water-flow, effectively improves trashrack discharge capacity, reduces energy consumption and water delivery cost.
