Trash-cleaning machine with trash-cleaning guide groove

Abstract

The invention discloses a trash-cleaning machine with a trash-cleaning guide groove. The trash-cleaning machine comprises a walking type gantry, a trash grabbing mechanism, the trash-cleaning guide groove, a guide groove lifting mechanism and a grab bucket lifting mechanism, the guide groove lifting mechanism and the grab bucket lifting mechanism are fixed on the walking type gantry, and the trash-cleaning guide groove is fixedly connected with the guide groove lifting mechanism; and the trash grabbing mechanism is fixedly connected with the grab bucket lifting mechanism, the lower part of thetrash-cleaning guide groove is provided with a lower supporting wheel, the walking type gantry is fixedly provided with an upper supporting wheel used for supporting the trash-cleaning guide groove,under control of the guide groove lifting mechanism, the trash-cleaning guide groove enters into water along the trash rack surface through the upper supporting wheel and the lower supporting wheel, and the grab bucket lifting mechanism is used for controlling the trash grabbing mechanism to rise and fall in the trash-cleaning guide groove. According to the trash-cleaning machine with the trash-cleaning guide groove, the technical problems that the guide groove does not exist in front of a trash rack in front of a dam of a hydropower station, the water flow speed of a plurality of river bed hydropower stations is high, and a trash-cleaning grab bucket cannot be inserted into floating objects on the surface for cleaning, and cannot slide down the trash rack to the deep underwater depth to clean suspended trash on the trash rack are solved.

Description

technical field [0001] The invention belongs to the technical field of water surface and underwater decontamination, and in particular relates to a decontamination machine with a decontamination guide groove. Background technique [0002] In water conservancy and hydropower projects, especially in hydropower stations, the trash rack is used as the first barrier of the water inlet of the generating set. Its function is mainly to intercept floating dirt in the water and prevent floating objects from flowing into the generating set through the water inlet. If the trash rack floats accumulate too much, once the trash rack is damaged, the float will flow into the generator set through the penstock, which will cause a major accident. [0003] At present, the cleaning machines commonly used in domestic hydropower stations mainly have two working modes. One is that the cleaning bucket of the cleaning machine enters the existing cleaning guide trough before the trash rack. Take the ...

Problems solved by technology

[0004] The purpose of the present invention is to solve the above-mentioned problems existing in the prior art, and to provide a cleaning machine with a cleaning channel. Soon, the dirt cleaning grab could not be inserted into the floating objects on the surface to clean up the floating objects on the surface, and it was unable to slide down the trash rack to a deeper level underwater to clean up the technical problems of underwater suspended dirt stored on the trash rack
