Ice breaking device for pumped storage power station

Abstract

The invention discloses an ice breaking device for a pumped storage power station and relates to the field of pumped storage power station ice breaking equipment. According to the technical scheme, the ice breaking device comprises a ship and is characterized in that a frame is arranged at one end of the ship, and the other end of the ship is provided with a motor box; the ship is sequentially provided with an ice breaking unit, a water pumping unit and a freezing preventing unit; the ice breaking unit comprises a crushing mechanism arranged at the front end of the motor box; the water pumpingunit comprises an oblique water pumping pipeline, and the freezing preventing unit is arranged below the upper-end water outlet of the water pumping pipeline. The ice breaking device has the advantages that the crushing mechanism of the device can crush preliminarily frozen thin ice on a lake surface, and downward impact force generated by the water outlet of the water pumping unit is used to drive a stirring rotary disc to rotate so as to generate disturbed water flow on the lake surface to prevent the lake surface from freezing; the freezing problem of a pumped storage power station reservoir in winter is solved, unit stable operation is guaranteed, reservoir area bank slope stability is increased, the service life of hydraulic facilities is prolonged, and good conditions are created for the safe and stable operation of the pumped storage power station.

Description

technical field [0001] The invention relates to the field of ice-breaking equipment for reservoirs of energy-storage power stations, in particular to an ice-breaking device for energy-storage power stations. Background technique [0002] The construction and operation of pumped storage power stations is crucial to the stable operation of the power grid. In mountainous areas, there is a large gap in hydropower resources, which is extremely beneficial to the construction of pumped storage power stations. However, in northern regions, both upper and lower reservoirs freeze in winter. If the ice layer is thick, when the water level of the reservoir changes sharply, it is easy to cause tears on the surface of the reservoir basin, seriously affecting the safe and stable operation of the unit and the stability of the bank slope in the reservoir area. This problem will greatly improve the safety and reliability of the pumped storage power station in winter, which is conducive to saf...
