Hydrological winch capable of reducing abrasion of steel wires

The invention relates to the technical field of hydrological monitoring equipment, and discloses a hydrological winch capable of reducing abrasion of steel wires. The hydrological winch comprises a winch body and a fixing frame, wherein one end of the fixing frame is fixedly connected to a connecting box. According to the hydrological winch capable of reducing the abrasion of the steel wires, a guide wheel of an existing metal material is replaced with fixed guide wheels of two sets of nylon, and a steel wire rope penetrating groove is formed between the fixed guide wheels of two sets of nylon to replace an existing single guide wheel, so that the contact areas between a steel wire rope and the guide wheels are reduced, and then the abrasion of the steel wire rope is further reduced; and the air cylinder is started to push a piston in an oil storage tank to move every one period of time, then lubricating oil in the oil storage tank is conveyed to a first spray head and a second spray head through a first oil outlet pipe and a second oil outlet pipe and then the lubricating oil is sprayed out, so that the contact positions between the fixed guide wheels of the nylons and the steel wire rope are lubricated, the abrasion between the steel wire rope and the fixed guide wheels of the nylons is reduced, and the service life of the steel wire rope is prolonged.
