AI Technical Summary

Technical Problem

Traditional manhole cleaning and protection methods have narrow coverage and poor structural stability, which cannot effectively protect the safety of workers and pedestrians, especially posing safety hazards during high-pressure water jet cleaning.

Method used

An integrated dredging and protection device was designed, comprising two symmetrical protective frames and a main protective frame. The device is connected by an inverted U-shaped buckle, and the length of the sliding rod and the fixed rod are adjusted by the sliding sleeve. The support rod and the stop rod are fixed, and the pulley facilitates the lowering of the equipment, forming a protective structure with a large coverage area and stability.

Benefits of technology

It achieves full coverage of manhole openings, improves construction safety, is applicable to manholes of different diameters, and improves construction efficiency and ease of equipment placement.

Abstract

The utility model belongs to the field of inspection well desilting construction, and particularly relates to a drainage pipe network inspection well desilting protection integrated device which comprises two symmetrical auxiliary protection frames, a long rod is fixed between the auxiliary protection frames, a plurality of short rods are vertically connected between the long rod and an inner side long frame, and a plurality of inverted-U-shaped buckles are outwards welded to the inner side faces of the auxiliary protection frames. The device further comprises a main protection frame, the two long frames of the main protection frame are connected with the inverted-U-shaped buckles on the two sides in a clamped mode respectively, the length of the main protection frame is adjustable, supporting rods are fixed to the two sides of the main protection frame, and stop rods are fixed to the bottom faces of the supporting rods. A fixed shaft is fixed to the main protection frame, a pulley is rotationally connected to the fixed shaft, and the pulley is located between the stop levers on the two sides. The device is large in coverage area and stable in structure, safety is guaranteed, the position of a well lid can be avoided, the protection area is not affected by the well lid, meanwhile, the length of the device can be adjusted according to the size of a well mouth, and the device can be suitable for dredging work of inspection wells with different calibers and is high in universality.
