Description

Technical Field

[0001] The present invention relates to the technical field of underwater pipelines, and particularly to an installation component for facilitating the underwater laying of diving pipelines. Background Art

[0002] Diving pipelines, also known as underwater paving pipelines, are pipeline products used for underwater paving. Depending on their materials and uses, the underwater pipelines have different size specifications. However, underwater pipelines need to have a certain strength and anti-corrosion performance; The invention with the publication number CN112923132B discloses a GRP pipeline underwater installation system and an installation method. The system includes an installation sling and positioning blocks that can be installed on an underwater bed; it can better ensure the positioning and fixing effect of GRP pipelines before backfilling construction, improve the construction effect. The installation method using this system can also avoid large-area bed leveling, improve construction efficiency, and reduce construction costs. For the assembly of underwater pipelines, workers need to wear diving suits and sink underwater for assembly. In order to prevent pollutants such as sediment from entering the pipeline, the ends of the pipeline will be blocked before the pipeline is put into the water, and at the same time, the inside of the pipeline will be pressurized. When the operator performs docking installation, the air pressure inside the pipe and the underwater outside will be adjusted to prevent a large amount of water from entering the pipeline. However, due to the continuous supply of high-pressure gas inside the pipeline, when the pipelines are docked, a reaction force will be exerted on the docked pipelines and the operators, so it is time-consuming and laborious to dock the pipelines. At the same time, because the pipelines are relatively heavy, and the operation of personnel underwater is different from that on the ground, it is not convenient to adjust the position of the pipeline when docking the bolt holes, and it is inconvenient to use.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Please see attached Figure 1-16, the present application provides the following technical solutions.

[0019] Embodiment 1: An installation component for facilitating the underwater laying of a diving pipeline, including an installation bracket 1, a first adaptor joint component, a second adaptor joint component, and two diving welded pipes 35. Two dragging and placing components are movably arranged on both sides of the upper end of the installation bracket 1. The dragging and placing component includes a moving support platform 4 and a placing guide seat 5. Two constraint chutes 2 are respectively arranged on both sides of the upper end of the installation bracket 1. The two sides of the two moving support platforms 4 are horizontally slidably inserted into the two constraint chutes 2 respectively. Two horizontal pushing cylinders 3 are respectively arranged horizontally at both ends inside the installation bracket 1. One side of the two horizontal pushing cylinders 3 is respectively connected to the moving support platform 4. By the horizontal pushing of the horizontal pushing cylinder 3, the moving support platform 4 can be controlled to move horizontally along the constraint chute 2. The horizontal pushing cylinder 3 can be controlled by hydraulic control or pneumatic control according to requirements, or can also be controlled by a screw drive method, and manually driven and controlled by an underwater hydraulic wrench in water.

[0020] A gear groove is formed inside the moving support platform 4. The placing guide seat 5 is placed on the upper end of the moving support platform 4. A rotating support shaft 6 is arranged at the center of the lower end of the placing guide seat 5. The lower end of the rotating support shaft 6 is rotatably inserted into the gear groove through a sealed bearing and is provided with an adjusting worm gear 7. One side inside the gear groove is horizontally provided with a control worm 8 through a bearing. One side of the control worm 8 is meshed and connected with the adjusting worm gear 7. The control worm 8 horizontally penetrates through the moving support platform 4 and is inserted into one side of the constraint chute 2. Two combined connection ears 9 are symmetrically arranged on both sides of the upper end of the placing guide seat 5, and two fixing clamps 10 are respectively provided in a pairwise corresponding manner at the upper ends of the four combined connection ears 9 through bolts. When the control worm 8 is rotated, the position of the placing guide seat 5 can be rotationally adjusted. Since a pipeline placing groove is arranged above the placing guide seat 5, the direction of the placing guide seat 5 can be adjusted according to the position of the pipeline, so that the pipeline is lapped with the placing guide seat 5.

The second adaptor joint assembly includes a second welding joint 12, a second combined base plate 14 and a second adaptor connecting plate 16. The first adaptor connecting plate 15 is movably and limit-inserted into one side of the first welding joint 11 through the first combined base plate 13. The second adaptor connecting plate 16 is movably and limit-inserted into one side of the second welding joint 12 through the second combined base plate 14. On the opposite sides of the first welding joint 11 and the second welding joint 12, there are respectively provided extrusion combined grooves 18. In the centers of the first adaptor connecting plate 15 and the second adaptor connecting plate 16, there are provided extension tubes. The two extension tubes are respectively inserted into the two extrusion combined grooves 18 and are provided with restraint convex rings 19. And the diameter of the restraint convex ring 19 is larger than the diameter of the extension tube and smaller than the diameter of the extrusion combined groove 18. On the side where the restraint convex ring 19 is inserted into the extrusion combined groove 18, there is sleeved an extrusion sealing sleeve 20. The first combined base plate 13 and the second combined base plate 14 are respectively movably sleeved on the extension tubes of the first adaptor connecting plate 15 and the second adaptor connecting plate 16. The inner diameters of the first combined base plate 13 and the second combined base plate 14 are smaller than the diameter of the restraint convex ring 19.

And between the first combined base plate 13 and the first adaptor connecting plate 15 and between the second combined base plate 14 and the second adaptor connecting plate 16, there are sleeved slit sealing rings 28. After the connection between the first adaptor connecting plate 15 and the second adaptor connecting plate 16 is completed, when there is lateral water flow disturbance at the connection position, the first adaptor connecting plate 15 and the second adaptor connecting plate 16 can twist and squeeze the extrusion sealing sleeve 20 through the restraint convex ring 19 in the extrusion combined groove 18 to achieve adaptive buffering. At the same time, when the restraint convex ring 19 squeezes the extrusion sealing sleeve 20, the sealing effect can be further enhanced. The installation of the first combined base plate 13 and the second combined base plate 14 is used for the assembly of the first adaptor connecting plate 15 and the second adaptor connecting plate 16 and applies an extrusion force to the extrusion sealing sleeve 20 to promote the connection sealing effect at the position between the extrusion sealing sleeve 20 and the restraint convex ring 19.

[0022] On the sides of the first adaptive connection disk 15 and the second adaptive connection disk 16 that are away from each other, several pairs of tension sleeves 21 are symmetrically arranged.

The restraint rods 26 are movably inserted into the second arc-shaped restraint grooves 27. The first adaptive connection disk 15 can only perform axial horizontal movement through the guiding insertion holes 22. The virtual axes of the first arc-shaped restraint groove 23 and the second arc-shaped restraint groove 27 are coaxial with the virtual axis of the second welding joint 12. Between the second adaptive connection disk 16 and the second combined base disk 14, relative position adjustment can be achieved by the arc-shaped structure of the tension sleeves 21 in the first arc-shaped restraint groove 23 for left and right adaptive rotational swinging, so that when the first welding joint 11 and the second welding joint 12 are butted, several tension sleeves 21 of the first adaptive connection disk 15 and the second adaptive connection disk 16 can be quickly adjusted to appropriate positions.

[0023] A docking component is provided to perform adaptive sliding on the docking of the first adaptive connection disk 15 and the second adaptive connection disk 16. The docking component is respectively arranged on the opposite sides of the first adaptive connection disk 15 and the second adaptive connection disk 16, and the docking component includes several conical docking grooves 32 and conical docking blocks 33.

When docking is required, the submersible welded pipe 35 is filled with an air pressure equal to the water pressure. At this time, the sealing plate is removed and docking can be carried out. During docking, the placement guide seat 5 controls the submersible welded pipe 35 equipped with the first welding joint 11 and the second welding joint 12 through the clamping of the fixed clamp 10 and the movement of the movable support platform 4, so that the first adaptive connection plate 15 and the second adaptive connection plate 16 on one side of the first welding joint 11 and the second welding joint 12 are docked.
