An automatic slag removal system for small and medium hydropower stations

Abstract

The invention discloses an automatic scum salvaging system of a medium-small hydropower station. The automatic scum salvaging system comprises a conveying mechanism, a scum salvaging mechanism, a scum storage pond and a controller. The scum salvaging mechanism is arranged on the side wall of a front pond and connected with the conveying mechanism, the conveying mechanism is connected with the scum storage pond, and the conveying mechanism and the scum salvaging mechanism are both connected with the controller through wires. According to the automatic scum salvaging system, the mode that the scum salvaging mechanism is arranged on the front pond is adopted, floating objects in a reservoir are continuously salvaged ashore and continuously conveyed through the conveying mechanism to the scum storage pond to be processed in a centralized mode, and automatic salvaging is achieved; the automatic scum salvaging system is simple in structure and easy and convenient to operate, the practical value of the automatic scum salvaging system is developed to be maximum degree under the same-class resource condition, and the automatic scum salvaging system is worthy of being popularized and applied.

Description

technical field [0001] The invention belongs to the technical field of hydropower station maintenance, and in particular relates to an automatic slag removal system for small and medium hydropower stations. Background technique [0002] At present, small and medium-sized hydropower stations use dams to store water and convert the potential energy of water into electrical energy through generators to generate electricity. However, due to the role of dams, floating objects in the upstream gather, especially in flood seasons. The accumulation of debris on the water surface not only requires a lot of manpower to salvage, but also seriously affects the water flow of the power generation channel due to its accumulation at the water inlet of the power generation channel, which in turn affects the power of the generator, resulting in insufficient power generation. The removal of the trash rack at the water inlet will cause the driftwood to enter the power generation channel and caus...

Problems solved by technology

[0002] At present, small and medium-sized hydropower stations use dams to store water and convert the potential energy of water into electrical energy through generators to generate electricity. However, due to the role of dams, floating objects in the upstream gather, especially in flood seasons. The accumulation of debris on the water surface not only requires a lot of manpower to salvage, but also seriously affects the water flow of the power generation channel due to its accumulation at the water inlet of the power generation channel, which in turn affects the power of the generator, resulting in insufficient power generation. The removal of the trash rack at the water inlet will cause the driftwood to enter the power generation channel and cause damage to the generator impeller, which seriously affects the power of the entire power supply area. , The daily float collection ship for hydropower stations that can float freely with the water level is composed of a grid-type circular rake machine, a rake-tooth circular conveyor belt machine, and a collection box connected between a hull to collect dirt for 24 hours. Intermittent, to ensure smooth water intake and normal power generation at the water inlet of the hydropower station

Although it solves the problem of salvage, it causes difficulties in the transportation of salvage floating objects, it is not easy to transfer, and the continuous working performance is not good. Therefore, a salvage system that can not only salvage floating objects but also operate for a long time is needed
