Hydraulic Grab Bucket & Sleeve Guided Manhole / Sewage Desilting
IPTeL Tracking ID: MS-CPDM-2018-085 [Patent Application No. – 201841041471], and Patent Application No. – 201841041470
The present invention relates to a device for effective cleaning of sanitary sewage manhole basins. The device provides with manhole desilting based on guiding of a grab-bucket hung from a flexible member guided by a rigid sleeve that allows access to all regions of a manhole basin for effective removal of silt from a manhole.
The invention provides benefits such as the specific combination of the mechanical elements of the device and their operation that facilitate effective desilting of manhole basins.
Background
Existing technologies for manhole desilting either require entry into the manhole by a human being that can be unsafe and unhygienic and use of manual tools that are time consuming and need lot of human effort. The grab buckets that are being used at present for the cleaning of the entire manhole basin do not provide good manoeuvrability.
There is a need to effectively clean the sewages and manhole basins without the entry of human being in the manhole.
The present invention closes this technology gap by enabling use of a device that comprises of multitude of spindle and winch operated flexible members such as cables or ropes to simultaneously operate the lowering of the bucket.
Technology
The present invention generally relates to a sewer dredging and desilting.
The principal invention provides a device for effective cleaning of sanitary sewage manhole basins quickly and economically. The device avoids manhole entry and manual desilting, providing access to the entire manhole basin by the design of a sleeve guided cable mechanism operated by a multitude of winches and automated coordination and control of a multitude of spindle operated winches for proper guidance and reach to all areas of manhole basin.
The device also allows reduction in the time taken to clean silt in the manhole basin since it is aided by spindles and winches. The use of winches reduces operator effort, especially when enabled by power sources such as hydraulics. The device provides better maneuverability and safety of the operators.
