Abstract

The utility model relates to a float type trash rack, composed of bars and a float arranged on the bars, wherein the edge of the bars is provided with a rack frame for fixation; the float is an enclosed hollow body; the distance among the bars of the rack is selective; the bars, the frame and the float are made from metal or metal composite material; the bars, the frame and the float are connected integrally, welded or bolted. One arrangement scheme of the float type trash rack is that: the rack is arranged in a trash rack groove to float up and down along water level; and another scheme is that the rack is fixed on wall and column via ropes to float up and down along water level. The float type trash rack combines a float with floating force and a trash rack with conservancy trash ability, to float up and down along water level, thereby stopping the dirty floating on surface.

Description

A kind of buoy type dirt-blocking grid

Technical field

The utility model relates to a kind of dirty equipment of blocking of hydraulic engineering that is applied in, specifically a kind of buoy type dirt-blocking grid.

Background technology

When in the more city river of dirt, building hydraulic structure such as pumping plant, adopt one trashrack or trash rake often can not effectively remove dirt, needing to establish in conventional trashrack or trash rake front dirts such as the duckweed blocking dirty facility together and will swim in the surface earlier, plastic lunch box, polybag tentatively tackles again, what alleviate conventional trashrack or trash rake blocks dirt or the pressure of removing contamination, enable operate as normal, guarantee that equipment such as water pump can normally move.Therefore, design a kind of can not give prominence to the water surface, with the dirty facility that blocks of civic landscape coordination be very necessary.

The utility model content

The purpose of this utility model has provided a kind of novel buoy type dirt-blocking grid that can fluctuate, can tackle near the floating pollutant water surface with fluctuation of water table, before being arranged at conventional trashrack or trash rake, block dirt or the pressure of removing contamination with what alleviate trashrack or trash rake.

For achieving the above object, the utility model has adopted following technical scheme:

The utility model discloses a kind of buoy type dirt-blocking grid, it is characterized in that: be made of trashrack grizzly bar and the floating drum that is arranged on the grizzly bar, the grizzly bar edge is provided with the trashrack framework with fixing.

Described floating drum is the sealed cavity body structure.

The trashrack interval of grid strip can be dredged as required can be close.The material of grizzly bar and framework, floating drum can be metal material, also can be metallic composite.Adopting whole the connection between grizzly bar and framework, the floating drum, can perhaps be bolt for welding.

A kind of scheme that the buoy type dirt-blocking grid are laid makes it to fluctuate with water level for being placed in the trashrack groove, and another kind of scheme fixedly makes it to fluctuate with water level on wall, the post for fastening with rope.

The floating drum that the utility model buoy type dirt-blocking grid will have buoyancy dexterously with have the trashrack that blocks dirty ability and carry out organic assembling, enable to fluctuate with fluctuation of water table, solved the problem of interception surface flotation dirt.

Description of drawings

Fig. 1 is the plan structure schematic diagram of the utility model buoy type dirt-blocking grid;

Fig. 2 is the facade structures schematic diagram of the utility model buoy type dirt-blocking grid.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described.

A kind of buoy type dirt-blocking grid as shown in the figure are made of trashrack grizzly bar 1 and the floating drum 3 that is arranged on the grizzly bar 1, and grizzly bar 1 edge is provided with trashrack framework 2 with fixing.

Described trashrack grizzly bar 1, floating drum 3 and trashrack framework 2 are metal construction.These members adopt whole the connection.

Described floating drum 3 is the sealed cavity body structure.

Trashrack grizzly bar 1 spacing can be dredged as required can be close.Grizzly bar 1 can be metal material with the material of framework 2, floating drum 3, also can be metallic composite.Adopting whole the connection between grizzly bar 1 and framework 2, the floating drum 3, can perhaps be bolt for welding.

A kind of scheme that the utility model buoy type dirt-blocking grid are laid makes it to fluctuate with water level for being placed in the trashrack groove, and another kind of scheme fixedly makes it to fluctuate with water level on wall, the post for fastening with rope.

Claims
