Abstract

The invention provides a trash cleaning device for a trash rack of a pumped storage power station. The trash cleaning device comprises a trash cleaning rake arranged on the water feeding side of the trash rack and a pulling mechanism arranged on a dike and used for driving the trash cleaning rake to move up and down. The trash cleaning rake comprises a rake tooth portion inserted into the trash rack; the pulling mechanism comprises supporting frames arranged on the dike, a pulling motor fixed on the supporting frames, a rotating shaft connected with an output shaft of the pulling motor and two suspension cables wound around the two ends of the rotating shaft, and the other ends of the two suspension cables are connected with the two ends of the trash cleaning rake respectively; a trash can is arranged at the portion, close to the upper portion of the trash rack, on the dike; the trash cleaning device also comprises a rotating mechanism for driving the trash cleaning rake to rotate and move to the upper portion of the trash rack. The trash cleaning device is simple in structural design, trash of the trash rack can be effectively cleaned, and trash in deepwater of the trash rack can also be cleaned.

Description

technical field [0001] The invention relates to the field of cleaning equipment for a pumped storage power station, in particular to a device for cleaning dirt from a trash rack of a pumped storage power station. Background technique [0002] In the upstream area of ​​the pumped hydropower station, a lot of dirt such as branches, leaves, and garbage bags often float in the reservoir, so a trash rack is installed at the water inlet of the turbine to prevent the dirt from entering the turbine, so as not to cause [0003] Head loss and damage to equipment. During the use of the trash rack, it bears a large amount of debris accumulation for a long time, which not only affects the use of the trash rack, but also causes the loss of water head, so it is necessary to clean the trash rack. [0004] The existing cleaning method is mainly to use machinery to clean up the dirt. It mainly uses a cleaning machine to remove the dirt in the pool, but it needs manual assistance, which is ti...
