The screw pump 2 is placed on one side of the front end of the top surface of the support platform 4.

[0034] The winding mechanism 5 comprises a wheel frame 5.1 whose bottom is fixed to the other side of the front end of the top of the supporting platform 4 and a reel 5.2 whose front and rear ends of the central axis are rotatably mounted on the front and rear ends of the top of the wheel frame 5.1. The oil-passing member 9 comprises a fixed ring 9.1 fixedly connected to the rear wall of the wheel frame 5.1, a disc 9.2 fixedly mounted on the center of the fixed ring 9.1, and a column 9.4 fixedly mounted on the rear end of the central axis of the reel 5.2. The front end of the disc 9.2 is rotatably mounted on the rear end of the column 9.4. A column groove 9.4.1 is arranged at the center of the rear wall of the column 9.4. The periphery of the column groove 9.4.1 is provided with a concentric annular groove 1 9.4.2 and annular groove 2 9.4.3. The rear wall of the disc 9.2 is respectively provided with oil inlet interfaces 9 at positions corresponding to the column groove 9.4.1, the annular groove 1 9.4.2 and the annular groove 2 9.4.3. 3. Hydraulic oil pipes 1 3 are respectively connected between the oil inlet interface 9.3 and the oil pump assembly (i.e., the oil inlet interface, the oil return interface and the oil overflow interface). Connecting pipes 9.5 are respectively mounted on the front wall of the column 9.4 at positions corresponding to the column groove 9.4.1, the annular groove 1 9.4.2 and the annular groove 2 9.4.3. An oil outlet interface 5.3 is mounted on one end of the outer peripheral wall of the central axis of the reel 5.2. The inner end of the oil outlet interface 5.3 is connected to the front end of the connecting pipe 9.5. A hydraulic oil pipe 2 6 is connected between the oil outlet interface 5.3 and the hydraulic motor of the screw pump 2. The hydraulic oil pipe 2 6 is wound on the central axis of the reel 5.2.

[0035] A sling 10 is also wound around the drum 5.2, wherein one end of the sling 10 is fixed to the central axis of the drum 5.2, and the free end of the sling 10 is connected to the lifting ring of the screw pump 2.

[0036] Three hydraulic oil pipes 2 6 and slings 10 are wound side by side on the central axis of the drum 5.2. In order to prevent the phenomenon of spreading and cross winding, the hydraulic oil pipes 2 6 and the slings 10 are fixed by a fixing member 7. Among them, the fixing member 7 includes a pair of detachable assembled clamping blocks 1 7.1 and 2 7.2. The clamping blocks 1 7.1 and 2 7.2 are respectively provided with semicircular grooves 1 7.1.1 and semicircular grooves 2 7.2.1 in pairs on the opposite surfaces. The cylindrical cavity composed of the semicircular grooves 1 7.1.1 and 2 7.2.1 is used to clamp the hydraulic oil pipes 2 6 and the slings 10. Among them, one end of the clamping block 1 7.1 and the clamping block 2 7.2 is rotatably sleeved with a rotating shaft 7.3, and the other end of the clamping block 1 7.1 and the clamping block 2 7.2 is threadedly sleeved with a closing bolt 7.4.

[0038] In summary, the walking wheels 4.1 at the bottom of the supporting platform 4 facilitate the rapid movement of the entire device to the work site.

[0039] One end of the oil pipeline is connected to the input port of the screw pump 2, and the other end is connected to the pipeline system for recovering oil, wherein the oil pipeline is a flexible pipeline with a surplus length to facilitate the delivery of the screw pump 2 to the oil floating area.

[0040] Then the screw rod 8.3 is rotated to support the support plate 8.4 on the plane, so that the whole device can be parked stably.

[0041] Then the screw pump 2 is slowly dropped to the surface of the floating oil, during which the reel 5.2 rotates slowly, so that the hydraulic oil pipe 2 6 and the sling 10 are spread out synchronously. In order to improve the dropping efficiency of the screw pump 2, a hydraulic motor can be installed on the wheel frame 5.1, and the hydraulic motor is used to drive the reel 5.2 to rotate, so as to realize the winding and spreading of the hydraulic oil pipe 2 6 and the sling 10.

[0042] When the input port of the screw pump 2 is immersed in the oil layer, hydraulic energy is provided by the oil pump assembly in the main box 1, so that the hydraulic motor on the screw pump 2 is operated to achieve suction of the floating.

[0043] After the floating oil is recovered, the hydraulic oil pipe 2 6 and the sling 10 can be wound by the reel 5.2 to lift and retract the screw pump 2.

[0044] In order to facilitate the rotation of the screw rod 8.3, a rotating wheel 8.5 is fixedly mounted on the top end of the screw rod 8.3.

[0045] In order to prevent the screw pump 2 from falling when the whole device is pushed, a guardrail 4.2 is provided on the outer edge of the front part of the support platform 4.
