[0054] At present, dry sandblasting or water sandblasting is generally used to treat the surface of wellhead tools. However, during the treatment process, the spray gun is directly held for spraying, and insufficient attention is paid to on-site splashing, noise, operation protection, sand and gravel recovery, etc. As a result, the site is chaotic and difficult to handle after the sandblasting is completed.

[0055] In view of this, the present invention provides a water sandblasting integrated system, including a skid-mounted room body 100, and a rotating platform 200, a water-sand collecting box, a folding protective cover 300 and a sandblasting control assembly 400 in the skid-mounted room body 100; wherein the rotating platform 200 is used to fix the tool to be sandblasted, and is configured to drive the tool to be sandblasted to rotate under the starting condition; the water-sand collecting box is arranged at the bottom of the rotating platform 200 and is connected to the rotating platform 200; the folding protective cover 300 is arc-shaped, surrounded by the rotating platform 200, and one end of the folding protective cover is connected to the water-sand collecting box, and the other end extends along the axial direction of the rotating platform 200 in a direction away from the rotating platform 200; the sandblasting control assembly 400 includes a spray gun 410, and the spray gun 410 is configured to extend into the space enclosed by the folding protective cover 300 under the sandblasting condition, and is located above the rotating platform 200.

[0056] In the water sandblasting integrated system, the spray gun 410 cooperates with the rotating platform 200 to realize 360° sandblasting of the sandblasting tool; after the water-sand mixture is sprayed out from the spray gun 410, the excess part and the part splashed to the folding protective cover 300 will be collected in the water-sand collection box under the action of their own gravity, so as to realize the recovery of water and sand; the whole system is integrated into the skid-mounted room 100 to form a whole, isolated from the outside world, and can be hoisted and transported as a whole to meet the needs of field operations.

[0057] It can be seen that compared with the prior art, the integrated water sandblasting system can prevent splashing on site during sandblasting, recycle excess water-sand mixture, and reduce noise. In addition, the operator does not need to hold the spray gun 410 and spray around the sandblasting tool, which improves safety.

[0060] The integrated water sandblasting system further includes a first drive assembly, which is in transmission connection with the second sub-protective cover to drive the second sub-protective cover to slide around the axis of the rotating platform 200. Here, optionally, the second sub-protective cover is provided with teeth extending along its circumference, and the first drive assembly includes a motor and a transmission gear, the motor is arranged on the skid-mounted housing 100, and the transmission gear is connected to the output shaft of the motor and is also meshed with the second sub-protective cover.

[0061] When the motor starts, the second sub-protective cover slides accordingly along the arc-shaped slide rail through cooperation with the transmission gear. For example, it slides toward the first sub-protective cover to overlap with the first sub-protective cover. At this time, the wellhead tool can be installed or removed; or it slides away from the first sub-protective cover to form a blocking space with the first sub-protective cover. At this time, sandblasting operations can be carried out, and the first sub-protective cover and the second sub-protective cover can block the splashing water-sand mixture.
