Novel automatic environment-friendly telescopic device

Abstract

The invention relates to a novel automatic environment-friendly telescopic device which comprises a rack and a hollow outer cylinder. One end of the outer cylinder is horizontally hinged to the rack,a telescopic mechanism is arranged between the outer cylinder and the rack, and the two ends of the telescopic mechanism are horizontally hinged to the rack and the outer cylinder correspondingly; theend, away from the rack, of the outer cylinder is open, an inner cylinder with two open ends is slidably connected into an opening of the outer cylinder, a hose is sleeved with the inner cylinder ina connected mode, one end of the hose extends out of the inner cylinder, and the hose and the inner cylinder are detachably fixed. By the adoption of the technical scheme, the inner cylinder can stretch into the drainage pipe from the ground conveniently, and clogging in the drainage pipe is removed. The other end of the hose can be connected with a suction pump and the like, and the hose is longer than the telescopic stroke of the inner cylinder. The hose and the inner barrel are detachably fixed, the inner barrels with different lengths can be replaced according to actual practical conditions, compared with an existing mode that the hose is directly connected through a hydraulic cylinder, the telescopic stroke of the inner cylinder and the telescopic stroke of the outer cylinder are convenient to adjust, and the hose can be conveniently replaced by adapting to different telescopic strokes.

Description

technical field [0001] The invention relates to the technical field of pipeline desilting, in particular to a novel automatic environment-friendly telescopic device. Background technique [0002] At present, urban underground drainage pipes are an important system to prevent urban waterlogging and drainage. For many urban branch drainage systems, the pipe diameters are only 600mm and 800mm. Such a small pipe diameter cannot be manually entered into the dredging operation, and can only rely on external equipment for dredging operations. [0003] The existing sedimentation sludge recovery device in the drainage pipeline is that the staff hold the suction hose nozzle connected to the recovery tank equipped with an air suction pump on the ground and enter the drainage pipeline to recover the sedimentation sludge from the suction hose nozzle to the ground. Complete the cleaning of the blockage in the drain pipe. [0004] The above-mentioned existing technical solutions have the...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the workload of dredging the drainage pipe by the staff holding the suction hose is relatively large, and the hose is easily shaken due to the suction effect during the work process. Easy to cause hazards to staff, so there is room for improvement
