Ship-borne fishing net cleaning device and method of use in approach channel waters of ship lift

Abstract

A ship-mounted fishing net cleaning device in approach channel waters of a ship lift and its use method, including a bottom plate on which a geared motor, a side plate, a base, a bearing base and a support are installed on the bottom plate, and a cam splitter is installed on the base , the output shaft of the cam divider is equipped with a first sprocket, the other end of the input shaft of the cam divider is equipped with a first bevel gear, the main shaft is installed between the two second bearing seats, and the second bevel gear is fixed on one end of the main shaft Gears, the first bevel gear meshes with the second bevel gear, and a cam is installed in the middle of the main shaft; the cam rotates through the L-shaped swing rod to drive the support arm to swing back and forth intermittently; the third bearing seat is installed on the two supports, and the roller shaft and the third The bearing seat hole is assembled, the machine cover is fixed between the two supports, the second sprocket is installed on the roller shaft, and the first sprocket and the second sprocket are driven by a chain. The invention realizes the automatic cleaning of the fishing net, improves the cleaning efficiency of the fishing net and the safety and stability of the operation of the ship lift.

Description

technical field [0001] The invention belongs to the technical field of water area cleaning of a ship lift approach channel, and in particular relates to a device for cleaning a ship-borne fishing net in a ship lift approach channel water area and a method for using the same. Background technique [0002] During the navigation process of the ship, there will be some discarded fishing nets scattered on the water surface in the approach channel upstream and downstream of the ship lift. The ship lift has high requirements on the speed limit of the ship during the navigation process, and can only sail at low speed. Major safety accidents such as irreversible damage to ship lift equipment and facilities when the ship stalls out of control. Due to the narrow approach channel and tight waterway resources, passing ships often have fishing nets entangled with propellers when passing through this water area, which poses a great safety hazard and affects the navigation efficiency and sa...

AI Technical Summary

Problems solved by technology

Due to the narrow approach channel and tight waterway resources, passing ships often have fishing nets entangled with propellers when passing through this water area, which poses a great safety hazard and affects the navigation efficiency and safe and stable operation of the ship lift. However, the cleaning of fishing nets is currently A more conventional manual cleaning method is adopted: for the fishing nets close to both sides of the approach channel, people manually clean them with simple fishing tools; The deployment and coordination of personnel takes a long time; the two cleaning methods are inefficient, take up a lot of navigation time and consume manpower and material resources

[0003] Existing fishing net cleaning devices, such as "a self-priming underwater cleaning device for fishing nets" disclosed in Chinese patent document CN 110090828 A, use propellers to generate suction to absorb fishing nets. This method tends to generate large vortices and consumes a lot of energy
