A supplementary trash rack's of decontaminating upper segment oblique grid leaf 3 is worn the strip 3.2 welding by upper segment grid 3.1 and upper segment and is formed, upper segment grid 3.1 be width 100 mm's lath, the upper segment wear the round steel that strip 3.2 is diameter 40 mm.
A lower section straight grid leaf 5 of supplementary trash rack of decontaminating is worn strip 5.2 welding by lower section bars 5.1 and lower section and is formed, lower section bars 5.1 be width 100 mm's lath, lower section wear strip 5.2 be diameter 40 mm's round steel.
Compared with the prior art, the utility model, its beneficial effect lies in: by additionally arranging the upper section inclined grid blade and the carrier roller device on the trash rack, mechanical trash removal of a hydropower station or a pump station which can not fall into the trash rack to complete trash removal originally caused by insufficient upstream limit position of a hoisting machine or a concrete beam in front of a trash rack orifice can be realized, the grab bucket can smoothly fall into the front of the trash rack, scraping and rubbing between a grab bucket hoisting steel wire rope and a grid bar are avoided, trash removal efficiency is improved, and labor intensity is reduced.
The utility model discloses simple structure, convenient to use, current trash rack can become the supplementary trash rack of decontaminating through simple transformation, can be applied to the equipment of decontaminating of newly-built power station or pump station and the equipment of decontaminating of current power station or pump station and reform transform, have extensive practicality.
