Problems solved by technology

However, this water level logging is an open logging well, and the residue and sundries on the slope are easily washed into the logging well by rainwater, covered on the float of the water level gauge or wrapped around the wire rope, causing the balance measurement system of the water level gauge to be destroyed , causing faults such as winding, jamming, and chute of the water level gauge steel wire rope, and large errors in the measurement accuracy of the water level, which have a greater impact on the safety of the hydropower station's flood control and the economic and rational operation of the reservoir

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.

Description

technical field [0001] The invention relates to a slag preventing device, in particular to a slag preventing device for a float water level gauge. Background technique [0002] The float water level gauge is composed of a float, a suspension cable, a counterweight, a water level wheel, a water level sensor, a bracket and an interface board. Using the principle of buoyancy, when the water level rises, the float generates upward buoyancy, so that the counterweight pulls the suspension cable to drive the water level rotation. Rotate clockwise, the display reading of the water level sensor increases; when the water level drops, the float sinks, pulling the suspension cable to drive the water level wheel to rotate counterclockwise, and the display reading of the water level sensor decreases. [0003] The float water level gauge is widely used in the water level station on the dam of the hydropower station, and the water level station on the dam is an important reservoir water lev...
