Abstract
The invention relates to a debris preventing device, in particular to the debris preventing device for a float water level gauge. The device comprises a filtering mechanism and even number groups of upright limiting assemblies located on the installation base of a water level gauge; the filtering mechanism comprises a filtering framework with openings formed in the top and bottom, a filtering netfixedly arranged on the filtering framework and a floating ball fixedly arranged on the filtering framework; the upright limiting assemblies comprise guiding pipes fixedly arranged on the side face ofthe filtering framework and guiding ropes with one ends arranged on the installation base of the water level gauge and the other ends penetrating through the guiding pipes and fixedly provided with weight balancing blocks; the guiding ropes are perpendicular to the water surface, the weight balancing blocks are located under the water, and pulling force impacting on the weight balancing blocks does not generated by the guiding ropes, and under the action of the buoyancy force of water, the up-and-down vertical movement along the guiding ropes of the filtering framework is constrained; the float of the water level gauge is located in the filtering framework. The device has the advantages of being simple in structure and capable of effectively preventing debris from generating influences onthe float water level gauge.
