Drawings
FIG. 1 is a schematic structural diagram of a mobile full-automatic trough cleaning system of the present invention;
Detailed Description
The technical scheme of the invention is further explained by combining the drawings and the embodiment.
Referring to fig. 1, the mobile full-automatic trough cleaning system provided by the invention comprises a pair of gantry supports 1, the two gantry supports 1 are connected through a mobile rail 2, longitudinal movement is realized through the gantry supports 1, the mobile rail 2 is connected with a mobile crane trolley 3, transverse movement is realized through the mobile crane trolley 3, the mobile crane trolley 3 is connected with a working platform through a suspension arm 4, and the depth position of the working platform is realized by adjusting the length of the suspension arm 4. The movable track 2 is a sectional track which can be lengthened or reduced, and the gantry supports 1 can be lifted and retracted within a certain range, so that the groove cleaning system can be suitable for wastewater tanks with all sizes and depths within a certain range. The system also comprises a PLC controller used for master control.
Preferably, the working platform comprises a submersible pump 5, a filter 6 and a densimeter probe 7 are installed at the pump head of the submersible pump 5, a circle of high-pressure water spray head 8 is installed at the front end of a water inlet of the submersible pump 5, the submersible pump is also connected with a clear water inlet pipeline 9 of the high-pressure water spray head, and a sewage outlet pipeline 10 is connected to a water outlet of the submersible pump 5.
Preferably, the submersible pump 5 is a high-flow and high-lift corrosion-resistant submersible sewage pump, and the impeller is provided with a high-chromium alloy cutter head.
Preferably, the clean water inlet pipe 9 and the sewage outlet pipe 10 are hoses, penetrate through the gantry support 1, are arranged along the boom 4 and are communicated with the working platform, a pulley is arranged in the hollow part of the boom at the upper end of the gantry support 1 and is used for conveying a pipeline, and guide rings are arranged at intervals on a traction lifting rope and are used for fixing the pipeline.
