A drainage pipe dredging device with flow distribution function

Abstract

The invention provides a drainage pipeline silt removing device with the flow distribution function. The device comprises a first installing unit and a second installing unit which are arranged in the silt entering direction, and an installing body of the first installing unit is the same as that of the second installing unit; a pushing cylinder used for changing the distance between the first installing unit and the second installing unit and a silt discharging unit used for discharging silt are arranged between the first installing unit and the second installing unit; the drainage pipeline silt removing device further comprises driving units corresponding to the installing bodies, and each driving unit comprises a driving cylinder and a gate; piston end heads of the driving cylinders are connected with the gates, and the gates are arranged in the corresponding installing bodies. By means of power flow distribution of the driving cylinders, the silt removing device can be accurately and reliably opened and closed in the working process of a drainage pipeline, and the slit removing work efficiency is improved.

Description

technical field [0001] The invention relates to a device for clearing up underground drainage pipe sludge, in particular to a drainage pipe dredging device with flow distribution function. Background technique [0002] The urban underground drainage system has important functions of preventing urban waterlogging and ensuring sewage discharge, so its treatment scale and work reliability directly affect the level of urban infrastructure. For many branch drainage systems, the design diameter of the drainage pipe is only 300-800mm. When it is necessary to clean up the sediment in the drainage pipe, it cannot be operated manually, so a sludge recovery device is usually used for operation. [0003] However, the existing silt recovery device is mainly that the staff holds the suction hose nozzle connected to the recovery tank equipped with an air suction pump on the ground and enters the drainage pipe, and the sedimentation silt is recovered from the suction hose nozzle to the reco...

Problems solved by technology

[0007] However, the inlet and outlet distribution of sludge in the pump of the dredging device depends on the negative pressure and positive pressure generated when the volume of the sludge pump changes to automatically drive the opening and closing of the valve. The sealing of the valve is feasible, but due to the complex composition of the silt accumulated in the drainage pipe, it contains particles, leaves, branches and other sundries of different scales. These sundries are likely to be stuck at the valve, making the seal of the valve invalid. The workplace where it is applied, the maintenance is not timely, the maintenance cost increases, and the work efficiency is indirectly reduced
