Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a cleaning device for offshore oil platforms. Background Technology

[0002] In offshore oil extraction, after completing deep well drilling, drill pipes inevitably accumulate a large amount of stubborn dirt on their surface, such as oil stains, thick mud, and various rock cuttings. Traditional cleaning methods for drill pipes mainly rely on manual scrubbing. Operators need to hold brushes or use water spray equipment to rinse the drill pipes, using the force of the water flow to wash away the dirt.

[0003] However, offshore operating space is limited, and drill pipes are large and heavy, making manual operation not only labor-intensive but also inefficient.

[0004] Furthermore, due to the limitations of manual operation, it is difficult to clean the surface of the drill rod in a comprehensive and thorough manner. Stains in some hidden parts and complex areas are difficult to remove completely. The rinsing power of the water spray equipment is also limited. For stubborn stains that are firmly attached, it is difficult to remove them effectively by simply relying on the force of the water flow, resulting in poor cleaning effect.

[0005] To address the aforementioned issues, we propose a cleaning device for offshore oil platforms. Utility Model Content

[0006] The purpose of this invention is to provide a cleaning device for offshore oil platforms to address the aforementioned shortcomings in the technology.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for offshore oil platforms, comprising a positioning cylinder and a rotating cylinder. The rotating cylinder is disposed on the inner wall of the positioning cylinder. Bearings are fixedly installed on the top and bottom inner walls of the positioning cylinder. The inner ring of the bearings is fixedly connected to the outer wall of the rotating cylinder. Annular metal brushes are fixedly installed on the top and bottom inner walls of the rotating cylinder. A gear ring is fixedly installed at the center of the outer wall of the rotating cylinder. A gear housing is fixedly installed on one side of the outer wall of the positioning cylinder through an opening. The gear housing and the positioning cylinder are connected to each other. A drive gear is installed on the inner wall of the gear housing. A vertically downward motor is located at the center of the top of the gear housing. The output shaft of the motor passes through the outer wall of the gear housing and is fixedly connected to the center of the top of the drive gear. The drive gear meshes with the gear ring.

[0008] Preferably, a fixing cover is fixedly provided on the top outer wall of the gear housing, and the motor is fixed to the inner wall of the fixing cover.

[0009] Preferably, a funnel-shaped cover is fixedly provided on the top outer wall of the positioning cylinder, and an annular hollow tube is fixedly provided on the inner wall of the funnel-shaped cover. Spray nozzles are installed at equal intervals through openings on the inner wall of the annular hollow tube.

[0010] Preferably, one side of the outer wall of the annular hollow tube is connected to a liquid guide tube through an opening, and a liquid guide tube connector is fixedly provided on the outer wall of one end of the liquid guide tube.

[0011] Preferably, a metal ring is fixedly provided on the outer wall of the positioning cylinder, and three equally spaced support plates are fixedly provided on the outer wall of the metal ring.

[0012] Preferably, the top outer wall of the three support plates is fixed with a vertically upward support rod, and a positioning piece is fixed at one end of the top of the support rod. The outer wall of the positioning piece has a positioning hole, and the inner wall of the positioning hole is equipped with a matching bolt.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] The output shaft of the electric motor drives the drive gear to rotate. Since the drive gear meshes with the gear ring on the outer wall of the rotating cylinder, it drives the rotating cylinder to rotate inside the positioning cylinder. The annular metal brush on the inner wall of the rotating cylinder rotates accordingly, thoroughly cleaning the surface of the recovered drill rod. The drill rod can be cleaned before it is recovered and lifted to the deck. It is not only highly efficient in cleaning, but also able to remove stubborn stains attached to the surface of the drill rod, resulting in a good cleaning effect. Attached Figure Description

[0032] Working principle of this utility model:

[0033] Refer to the instruction manual appendix Figure 1-4When using this utility model, first move it to the corresponding position at the bottom of the drilling platform deck opening. Using the positioning hole 18 on the top positioning plate 17 of the support rod 16, pass the bolt through the positioning hole 18 and tighten it to fix it at the preset installation position at the bottom of the drilling platform deck opening. After installation, connect the fluid guide pipe connector 14 to the external cleaning fluid supply device. When the drill rod exploration is completed and the drill rod is retrieved, the drill rod moves upward. At this time, the drill rod is cleaned, and the motor 7 is started. The output shaft of the motor 7 drives the drive gear 8 to rotate. The drive gear 8 meshes with the gear ring 9 on the outer wall of the rotating cylinder 2, thereby driving the rotating cylinder 2 to rotate inside the positioning cylinder 1. The annular metal brush 4 on the inner wall of the rotating cylinder 2 rotates accordingly, turning on the external cleaning fluid supply device. The cleaning fluid enters the annular hollow tube 11 through the liquid guide pipe 13, and then is sprayed out from the equally spaced nozzles 12, spraying onto the surface of the drill rod. As the drill rod moves upward, the rotating annular metal brush 4 brushes the surface of the drill rod, and the cleaning fluid sprayed from the nozzles 12 rinses the drill rod. The two work together to achieve a comprehensive cleaning of the drill rod.
