Abstract

The invention discloses a movable type drain grating device arranged at the water inlet of a hydropower station and capable of intercepting water surface trash. The movable type drain grating device comprises a left stand column, a right stand column, trash rack supporting bars and trash racks. The trash racks are of a unit combined structure. Each trash rack is composed of a drain grating net, a drain grating support shaped like a Chinese character 'hui' and clamping hooks. Each drain grating net is fixedly connected into an inner frame formed by the corresponding drain grating support shaped like the Chinese character 'hui'. The corresponding clamping hooks are fixedly connected to each drain grating support shaped like the Chinese character 'hui'. The trash rack supporting bars are provided with clamping grooves matched with the clamping hooks. According to the movable type drain grating device, the height of each trash rack can be adjusted freely according to variation of the water level; the trash racks are of the unit combined structure, so that maintenance and replacement are facilitated; the amount of trash intercepted by the trash racks can be sensed and detected in real time, the trash can be cleaned up in time, the problem of manual field detection is solved, and time and labor are saved.

Description

technical field [0001] The invention belongs to the technical field of waste disposal in hydropower stations, and in particular relates to a movable waste-blocking device arranged at a water inlet of a hydropower station and capable of intercepting waste on the water surface. Background technique [0002] A hydroelectric power station is a comprehensive engineering facility that can convert water energy into electrical energy. It generally includes a reservoir formed by water retaining and drainage structures, a water diversion system for a hydropower station, a power plant, and electromechanical equipment. Usually, the dams of small and medium-sized hydroelectric power stations are built due to the terrain. Because the waterways are narrow, they are greatly affected by the natural environment. Dirt and debris floating in the water, such as branches, leaves, weeds, and even domestic garbage often threaten For the normal operation of the generating set, it is necessary to set...
