Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the range of protection of the utility model.

[0021] As Figures 1 to 6 The utility model provides an oil selection arm, including jar body main part 1, the inside of jar body main part 1 is provided with rotary structure 3, one end of rotary structure 3 is fixedly installed with oil outlet pipe 2, one side of oil outlet pipe 2 is fixedly installed with oil delivery pipe 15, the outer surface of oil delivery pipe 15 is fixedly installed with limit pull rod 9, one end of limit pull rod 9 is fixedly installed with hose 12, one side of hose 12 is fixedly installed with liquid inlet disc 13, the top of liquid inlet disc 13 is fixedly installed with float frame 6, the inside of float frame 6 is provided with limit groove 17, the inside of limit groove 17 is movably installed with mounting plate 16, the top of mounting plate 16 is fixedly installed with first float 4, and steel wire rope 14 presents two same shapes, the top of mounting plate 16 is fixedly installed with steel wire rope 14, the inside of jar body main part 1 is fixedly installed with inner floating roof 10, and inner floating roof 10 and liquid inlet disc 13 are fixedly connected through steel wire rope 14, rotary joint support 8 is fixedly installed between rotary structure 3 and oil outlet pipe 2, and rotary joint support 8 presents trapezoidal shape, the inside of jar body main part 1 is fixedly installed with floating roof track 11, and floating roof track 11 presents arc shape.

[0022] When the liquid level of jar body main part 1 changes, the first float 4 with smaller density is lifted and lowered by buoyancy, driving the oil outlet pipe 2 to float synchronously through the rotary structure, ensuring that the oil outlet is always below the liquid surface. During the feeding and discharging process, the pressure transmitter and ultrasonic level meter monitor the liquid level and equipment operating parameters in real time, forming a closed-loop control. The flexible hose added between the liquid inlet disc 13 and the oil outlet pipe 2 effectively buffers the vibration caused by liquid surface fluctuations, preventing the oil outlet pipe 2 from shaking and ensuring stable operation of the system. The entire mechanism is driven by buoyancy, with sensing monitoring and mechanical buffering working together to achieve self-adaptive tracking and stable oil discharge. Compared with traditional oil pipe arms, this oil pipe arm constructs a dynamic buffering system through a flexible connecting hose 12. When the liquid surface fluctuates, the hose 12 elastically deforms to effectively absorb the radial shaking force, and the universal adjustment feature of the rotary structure 3 bearing allows the oil outlet pipe 2 to only produce axial following displacement, significantly reducing the impact of fluid disturbance on oil delivery stability. The liquid inlet disc adopts an inverted umbrella-shaped structure design, which effectively increases the effective oil recovery radius after unfolding. Combined with the uniformly distributed flow guide pores on the disc surface, the oil collection area is expanded while maintaining low flow resistance characteristics. The double-closed-loop control model constructed by the liquid level monitoring system ensures that the oil outlet is always in the best oil recovery area. The actual measurement data shows that the disturbance resistance of the device is improved, and the overall oil recovery efficiency is increased.
