DETAILED DESCRIPTION

[0022] The utility model will be further described below in combination with the drawings and specific embodiments.

[0023] As Figures 1 to 3 shown in the water conservancy project trash rack cleaning equipment, including installation in the river traffic bridge above the guide rail of trash rack, with the guide rail for use of mobile drive base, mobile drive base is installed with workbench 2; Workbench 2 is installed with hydraulic system 22, cab 21 and boom, workbench 2 is not only the installation basis of hydraulic system 22 and cab 21, but also carries the whole boom system. The boom is also provided with boom cylinder 33, and the various actions of the boom are controlled through the boom cylinder 33; The hydraulic system 22 converts hydraulic energy into mechanical energy through the cooperation of precise hydraulic pump and control valve, drives the boom to complete various actions, and the control system configured by the cab 21 enables the operator to easily and accurately control the movement and speed of the boom. It also includes a cleaning mechanism installed at the end of the boom away from the workbench 2; The boom connects the workbench 2 and the cleaning mechanism, and the cleaning mechanism is rotatably connected with the boom; The cleaning mechanism is used for cleaning the attachments on the surface of the trash rack. During river management, the boom is adjusted by the boom cylinder 33 to make the cleaning mechanism clean the attachments such as organisms and screws on the surface of the trash rack.

[0024] On the basis of the above, as Figure 1 and Figure 2 shown, the mobile drive base includes a rotating platform 1, four rotating supports 11 installed below the rotating platform 1, and a track wheel 12 installed at the end of each rotating support 11 away from the rotating platform 1 for use with the guide rail.
