Trash boom is set in front of the intake of power station to effectively intercept floating trashes in the upstream water of the power station and ensure that the inlet and spillway facilities of the power station are clear. The good operation condition of the trash boom/floating barrier is an important factor to improve the efficiency of the unit and ensure the safe and stable operation of the power station.
We own more than 20 invention and utility model patents for the trash boom/floating barrier in front of the hydopower station dam, such as trash barrier and floats guiding device, load monitoring system of trash boom/floating barrier, self-collapsing device of trash boom/floating barrier, anti-sinking floating body and so on. Having won the national power construction scientific and technological progress “First prize”, our technology of floating interception in hydroelectric engineering is at an advanced level in the world.
We have successfully supplied and installed many trash booms to the customers at home and aboard.
