when the elastic membrane 26 intermittently swells, the grid plate 28 can be driven to shake back and forth, a further disturbance effect is achieved on water flow passing through the grid plate 28, and meanwhile, when the grid plate 28 shakes back and forth, the telescopic bag 27 can be extruded back and forth, so that the water flow in the telescopic bag 27 can be extruded and sucked back and forth through the air holes, and the turbulence effect of the water flow is further improved; when the roller 20 drives the arc-shaped part 30 adsorbed with the lubricating oil to move to the surface of the bump 7, the roller 20 and the bump 7 can extrude the arc-shaped part 30, and the lubricating oil in the arc-shaped part can fully flow out, so that a more effective lubricating effect can be achieved on the surface of the bump 7; when the roller 20 is in a static state, the sealing film 31 can be blocked in a gap between the escape cavity 29 and the side wall of the roller 20 at the moment, so that the situation that the lubricating oil in the conveying strip 22 accidentally flows out is reduced, and when the roller 20 drives the lubricating body 21 to contact with the end part of the conveying strip 22 and continuously rotate anticlockwise, the magnetic block 16 at the lubricating body 21 can apply repulsive force to the flexible magnetic strip 33 at the moment, so that the sealing film 31 is far away from the lubricating body 21, the acting force applied by the sealing film 31 to the passing lubricating body 21 is reduced, further, the lubricating body 21 can smoothly take out the adsorbed lubricating oil and smoothly extrude the lubricating oil after the lubricating body is in contact with the surface of the bump 7, and the lubricating body 21 can smoothly lubricate the surface of the bump 7.
