Riverway floating object recovery and treatment method

Abstract

The invention discloses a riverway floating object recovery and treatment method. The riverway floating object recovery and treatment method comprises the following steps that a hydraulic cylinder is started, and a jacking rod drives a supporting pillar to move forwards under pushing of the output end of the hydraulic cylinder; a fence body quickly moves up and down in a guide rail groove under the traction of a connection rod, a screw rod is manually adjusted, a movable block can move on the connection rod, a movable block makes a lower raking pawl to open under driving of the connection rod, and the fence body moves downwards into the water; an upper raking pawl blocks floating objects to prevent the floating objects from continuous moving, the screw rod is reversely rotated, and the lower raking pawl automatically moves downwards and is matched with the upper raking pawl so as to hold the floating objects; and finally, the fence body is overall lifted under traction of the connection rod, and the collected floating objects are stacked to a fixed treatment site. When opening and closing of the lower baking pawl are adjusted, one screw rod is adopted to be matched with the movable block; opening and closing of the lower baking pawl can be achieved by forward and reversely rotating the screw rod; and it is obtained by calculation that 17 times power can be saved for adjusting the screw rod, and the work difficulty of opening and closing of lower raking pawl is lowered.

Description

technical field [0001] The invention relates to a sewage cleaning structure of a hydropower station, in particular to a method for recycling and treating floating objects in a river course. Background technique [0002] In reservoirs or rivers with a lot of sewage, in order to ensure the safe and normal operation of hydropower stations or pumping stations, it is often necessary to install sewage cleaning equipment so that the sewage can be cleaned without shutting down or emptying the reservoir. At present, small hydropower stations generally rely on manual cleaning. Most low-head and high-flow power stations, due to untimely cleaning, make the water pressure difference between the front and rear of the trash rack greatly exceed the design standard. Shutdown during the flood season for cleaning and safe operation of the trash rack It becomes a problem during power generation in flood season; while large-scale hydropower stations use bucket cleaning machines or rotary cleanin...

Problems solved by technology

[0003] Most of the two types of cleaning machines are fixed in front of the water inlet of the riverbed hydropower station to facilitate the cleaning of floating objects on the water surface; but near the riverbed water inlet, the two types of cleaning machines are unable to salvage the floating objects And, especially when the gate is opened, the water flow speed at the water inlet of the riverbed hydropower station is accelerated, which makes the efficiency of the cleaning machine low when salvaging, and the floating objects on the water surface will quickly flow into the riverbed water inlet with the water flow, forming floating objects to block The impact of the door slot of the water building will cause damage to the main body of the water retaining building; when realizing the opening and closing of the lower claw, the hydraulic method is generally used to realize the movement of the lower claw, and the small cleaning machine uses a steel rope to move the lower claw. The rake claws are pulled to realize the movement of the lower rake claws. Both methods have their own advantages, but the hydraulic starting method itself has a large weight, which increases the working load of the cleaning machine, while the steel rope manual pulling method has its own advantages. When encountering a large number of floating objects, the intensity of manual work is greatly increased and the efficiency is low
