AI Technical Summary
Because the underwater pin shaft in existing water conservancy facilities is under the water for a long time, it cannot be refueled or lubricated on time or as needed, resulting in huge noise during the opening and closing of the gate, causing noise pollution.
An underwater pin structure with a self-lubricating system is designed, including opening an oil cup hole at the outer end of the pin, opening a number of oil outlet holes on the outer circumference surface, and opening an internal oil circuit between the oil cup hole and oil outlet hole , convenient for filling lubricating oil.
Through the design of the self-lubricating system, it ensures that the pins are basically free of abnormal noise when the gate is opened and closed, which significantly improves noise pollution.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy equipment, in particular to an underwater pin shaft structure with a self-lubricating system. Background Art
[0002] In the existing water conservancy facilities, such as Figure 1 As shown, the gate 1 is generally suspended by two steel wire ropes 2, and the gate is opened and closed by a winch 3. There is a connecting pin 6 between the movable pulley 4 on the gate 1 and the gate's lifting lug 5. Since the pin 6 is under the water surface for a long time, it cannot be lubricated on time or as needed, resulting in huge noise during the opening and closing process of the gate, which constitutes noise pollution.
[0003] Technicians in this technical field are committed to solving the above-mentioned technical defects. Utility Model Content
[0004] In view of the above-mentioned defects of the prior art, the technical purpose of the utility model is to provide an underwater pin structure that is easy to lubricate.
[0005] In order to achieve the above technical objectives, the utility model provides an underwater pin shaft structure with a self-lubricating system, including a pin shaft arranged between a movable pulley and a lifting ear of a gate; the pin shaft is provided with a self-lubricating system; the self-lubricating system includes an oil cup hole opened on the outer end of the pin shaft; a plurality of oil outlet holes opened on the outer circumferential surface of the pin shaft; an internal oil circuit opened inside the pin shaft and passing through the oil cup hole and the oil outlet hole.
[0006] Furthermore, a plurality of oil grooves are provided on the outer circumferential surface of the pin shaft.
[0007] Furthermore, a butter cup is provided on the oil cup hole.
[0008] Beneficial effects of the utility model:
[0009] Due to the structural design, the utility model can conveniently add lubricating oil to the shaft pin by arranging the oil cup hole and the internal oil circuit, so as to ensure that the shaft pin has basically no abnormal sound when the gate is opened and closed, thereby improving noise pollution.
