Description
Technical Field
The invention belongs to the technical field of trash rack cleaning, and particularly relates to a trash rack cleaning device and a trash rack cleaning method.
Background
The trash rack is generally arranged at the water inlet and is used for blocking dirt such as pasture and water, drifting wood and the like carried by water. According to the position and the area of the power station and the water inflow demand, the water flow of each water inlet is different, so that the structure of the water inlet is also different in arrangement form according to the difference of the water flow, and the corresponding trash rack shape is also different. At present, most old power stations with trash racks arranged at the water inlets of the power stations have low trash cleaning demands due to less trash in river channels in the early years, and the trash cleaning machine is not considered to be arranged to clean the trash on the surface of the curved trash rack during the construction of the power stations, but the trash on the surface of the trash rack is cleaned in a mode of lifting the trash rack out of the water surface. However, in recent years, along with the increase of river sewage, the way of lifting the trash rack out of the water surface for trash cleaning is low in trash cleaning efficiency, and when the trash rack is lifted for trash cleaning, a generator set is required to be stopped, so that the power generation work cannot be normally performed, and the power generation benefit of a power station is seriously affected. In order to improve the dirt cleaning efficiency of the surface of the water inlet trash rack, the generating time of a unit is reduced to be influenced by the cleaning work of the trash rack, and a trash remover is added on the basis of a building to perform the trash cleaning operation of the surface of the trash rack.
The trash remover comprises lifting equipment and a trash cleaning grab bucket, a steel frame is fixedly arranged on the concrete foundation above the water inlet in use, the trash cleaning grab bucket is arranged on the steel frame through the lifting equipment, the conventional trash cleaning grab bucket is vertically arranged, the trash cleaning grab bucket can be directly controlled to move up and down along the surface of the trash rack through the lifting equipment, and the trash cleaning operation requirement is met. For the water inlet that extends outwards and incline to setting along concrete foundation side in the power station, its trash rack corresponds to be the slope and arranges in concrete foundation's outside. The steel frame is directly arranged on the concrete foundation, the cleaning grab bucket is suspended through the lifting equipment, the cleaning grab bucket and the trash rack are vertically staggered and opposite, the cleaning grab bucket cannot accurately fall on the trash rack when directly descending through the lifting equipment, and if the cleaning grab bucket is manually assisted to descend, the operation is difficult, the labor intensity is high, and the potential safety hazard is large. If the steel frame is directly extended outwards to the upper part of the trash rack and the trash grab bucket is suspended by the lifting equipment, the steel frame can be integrally formed into a structure similar to a cantilever because the upper part of the trash rack is not provided with a concrete foundation and can be fixed with the extension part of the steel frame, the trash grab bucket and the lifting equipment thereof have large weight, the strength of the steel frame structure is difficult to ensure the reliability of operation and bearing, and great potential safety hazards exist.
