Description

Technical Field

[0001] The utility model relates to a drain water seal pipe structure in a dangerous area of a drill floor. Background Art

[0002] During drilling operations, the entire drill floor area is a dangerous area. When discharging the sewage drain pipe on the drill floor deck, a water seal needs to be set for discharging to other safe areas. The conventional water seal form is the water seal form using a U-shaped pipe. This water seal form occupies a large space and is inconvenient to clean when blocked, which has a certain impact on the slip of the jack-up drilling platform. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a drain water seal pipe structure in a dangerous area of a drill floor.

[0004] The technical solution adopted by the utility model to achieve the above purpose is: a drain water seal pipe structure in a dangerous area of a drill floor, which includes an external pipe (1), an internal pipe (2), a water inlet (3), a top flange inspection opening (4) and a bottom flange inspection opening (6). The internal pipe (2) is arranged inside the external pipe (1), and a height difference is formed between the top of the internal pipe (2) and the top of the external pipe (1). The water inlets (3) are respectively arranged on the left and right sides of the external pipe (1). The top flange inspection opening (4) and the bottom flange inspection opening (6) are respectively arranged at the top and bottom of the external pipe (1). The bottom of the internal pipe (2) is provided with a water outlet (7).

[0005] A drain port (5) for discharging residues is arranged at the bottom of the external pipe (1).

[0006] The drain water seal pipe structure in a dangerous area of a drill floor of the utility model has a simple structure, occupies a small space, is convenient for later cleaning and maintenance, is arranged at the middle position under the drill floor deck, does not affect the left and right slip of the drill floor, has important significance for the water seal design of the drill floor drain system, and at the same time lays a foundation for the optimization of the drill floor pipeline design of subsequent offshore engineering projects.

[0011] As Figure 1 and Figure 2 shown, the drain water seal pipe structure in the dangerous area of the drill floor includes an external pipeline 1, an internal pipeline 2, a water inlet 3, a top flange inspection opening 4 and a bottom flange inspection opening 6. The internal pipeline 2 is arranged inside the external pipeline 1, and there is a height difference between the top of the internal pipeline 2 and the top of the external pipeline 1. The water inlets 3 are respectively arranged on the left and right sides of the external pipeline 1. The top flange inspection opening 4 and the bottom flange inspection opening 6 are respectively arranged at the top and bottom of the external pipeline 1. The bottom of the internal pipeline 2 is provided with a water outlet 7, and the bottom of the external pipeline 1 is provided with a drainage opening 5 for discharging residues. The external pipeline 1 is connected to the left and right two sewage inlets 3. When drain water flows into the external pipeline 1, the sewage enters the pipeline interior. When the height of the drain water is higher than the overflow opening at the top of the internal pipeline 2, the drain water is discharged from the internal pipeline 2 to a safe area. The height difference formed between the water inlet 3 of the external pipeline 1 and the overflow opening of the internal pipeline 2 is the water seal height. The top flange inspection opening 4 is used for daily inspection and maintenance, and the drainage opening 5 is arranged at the bottom of the external pipeline 1 for daily discharge of residues. The bottom flange inspection opening 6 at the bottom is connected for use during major repairs and cleaning; the drain water seal pipe structure in the dangerous area of the drill floor of the present utility model has a simple structure, occupies a small space, is convenient for later cleaning and maintenance, is arranged in the middle position under the drill floor deck, does not affect the left and right sliding of the drill floor, has important significance for the water seal design of the drill floor drainage system, and at the same time lays a foundation for the optimization of the drill floor pipeline design in subsequent offshore engineering projects.
