Technical Field

The invention relates to an intercepting device for a water inlet channel of hydropower equipment.

Background

Hydroelectric power generation is a way of generating electricity, and the utilized water energy is mainly potential energy accumulated in water. The natural water flow is gathered by building to form water head, and the water flow is collected and regulated by reservoir. When water flows through the water turbine, the water turbine is pushed by the water flow to rotate, the water turbine drives the generator to generate electricity, mechanical energy is converted into electric energy, and the electric energy is transmitted to users through the power transformation and power transmission and distribution equipment. The water energy is a renewable energy source in the nature and is repeatedly regenerated along with hydrologic cycle. The hydraulic power generation does not consume fuel during operation, and the operation management cost and the power generation cost are far lower than those of a coal-fired power station. The hydroelectric power generation does not generate chemical change in the process of converting water energy into electric energy, does not discharge harmful substances, and has small influence on the environment, so that the hydroelectric power generation is clean energy.

However, in actual operation, it is found that suspended matters in water can be involved into a generator set, and in the existing treatment mode, a grid net is installed at a water inlet position of the generator set, and the suspended matters are intercepted by the grid net, but the grid net is often blocked, so that the water inlet quantity in the generator set is insufficient.

Based on the above problem, we have designed one kind and can cooperate the grid net to protect, intercepts the water that enters into the inhalant canal, effectively reduces the hydroelectric power generation equipment water inlet channel intercepting device that the plankton got into in the generating set.
