Multi-multiplying-power lifting mechanism of mechanical decontamination slusher

Abstract

The invention discloses a multi-multiplying-power lifting mechanism of a mechanical decontamination slusher. The multi-multiplying-power lifting mechanism is used for decontamination work of dirty blocking railings of a water inlet of a water turbine of a power station or a water guide opening of a pump station; and the multi-multiplying-power lifting mechanism comprises a hoist steel wire rope (6), a slusher opening steel wire rope (5), a multi-multiplying-power lifting tool (8) of the hoist steel wire rope (6), a multi-multiplying-power lifting tool (7) of the slusher opening steel wire rope (5), a winding drum device (2) for winding the hoist steel wire rope (6) and the slusher opening steel wire rope (5) at the same time, a driving mechanism (1) of the winding drum device (2) and a rack (3) of the lifting mechanism. Compared with the prior art, a steel wire rope winding and unwinding device (4) for opening and closing the slusher is further arranged at the tail end of the slusher opening steel wire rope (5), and the problem that the volume of the lifting mechanism is obviously increased due to increase of the slusher volume and the dead load of the mechanical decontamination slusher is solved; meanwhile, an opening and closing mechanism is simplified, so that the overall decontamination device is simpler and more compact; and the reliability of the device is improved, and the overall investment of the device is reduced.

Description

technical field [0001] The multi-rate lifting mechanism of the mechanical cleaning rake bucket of the present invention relates to a mechanical device for cleaning the trash rack at the water inlet of the hydro turbine of the power station or the water diversion port of the pump station. Cleaning work of the trash rack. Background technique [0002] Trash racks are generally installed at the water inlet of hydro turbines in power stations or water diversions of pump stations to intercept dirt in the water to prevent the dirt from endangering the safe operation of turbines or pump stations. The dirt attached to the surface of the trash rack and the dirt accumulated in front of the trash rack should generally be removed by cleaning equipment, so as to prevent these dirt from causing head loss and endangering the safety of the trash rack. This type of cleaning equipment is generally used in conjunction with the cleaning bucket. In the prior art, the lifting mechanism is common...

AI Technical Summary

Problems solved by technology

The problem with this type of structure is that when the bucket capacity and self-weight of the mechanical cleaning bucket increase, the capacity of the lifting mechanism will also increase significantly, resulting in a significant increase in investment in cleaning equipment

At the same time, the structure of the opening and closing mechanism separately set up to control the bucket opening wire rope is complicated and occupies a large space, which also increases the overall investment of the cleaning equipment
