Mechanically pressurized cleaning rake bucket that can be connected to a multi-rate spreader

Abstract

The invention discloses a mechanical pressurization type decontamination slusher capable of being connected with a multi-multiplying-power lifting tool. The mechanical pressurization type decontamination slusher 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; the mechanical pressurization type decontamination slusher comprises a slusher support (4), a rotating slusher claw (5) and a slusher guide device (3); compared with the prior art, the slusher further comprises a lifting connecting rod mechanism (6) connected with a hoist steel wire rope multi-multiplying-power lifting tool (1) and a slusher opening connecting rod mechanism (7) connected with a slusher opening steel wire rope multi-multiplying-power lifting tool (2); and the method that the lifting connecting rod mechanism (6) and the slusher opening connecting rod mechanism (7) are additionally arranged, and the upper ends of connecting rods of the lifting connecting rod mechanism (6) and the slusher opening connecting rod mechanism (7) extend out of the top of the slusher support is used, so that the mechanical pressurization function is achieved, and meanwhile the multi-multiplying-power lifting tool can be conveniently connected with the decontamination slusher.

Description

technical field [0001] The mechanically pressurized dirt-cleaning rake that can be connected to a multi-rate spreader of the present invention relates to a mechanical device used for cleaning trash racks at the water inlet of a hydro turbine in a power station or a water diversion port in a pump station. The present invention is matched with this mechanical device , Carry out the 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. The cleaning bucket is a cleaning device used ...

Problems solved by technology

In the use of the prior art, there is another mechanically pressurized cleaning rake bucket. Both the hoisting wire rope and the opening wire rope of the cleaning rake bucket are connected to the rotating claws. The supporting twist connected to the bucket frame transfers the gravity of the bucket frame to the claws to pressurize the rotating claws and improve the cleaning effect. However, the problem with this cleaning bucket is that it is directly or indirectly related to the rotating claws Both the hoisting wire rope and the bucket opening wire rope are just a single wire rope, that is, the connection between the cleaning rake bucket and the cleaning equipment that operates it is realized by a single-rate spreader. This connection limits the cleaning equipment. Structural type, when the weight of the cleaning rake bucket needs to increase, the investment of the cleaning equipment will also increase significantly, so that the investment of the entire cleaning project will increase significantly
