Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
With reference to fig. 1 to 6, the axial length of the first and second telescoping devices in the natural state is greater than the distance between the two end cap sleeves, and the axial length in the pumping state is less than the distance between the two end cap sleeves. The rubber sealing ring is arranged at the end part of the first telescopic device, namely the inner surface of the rubber sealing ring is attached to the outer surface of the end part of the first telescopic device, and the outer surface of the rubber sealing ring is attached to the end cover sleeve of the frame. The outer diameter of the end part of the rubber sealing ring is slightly smaller than the inner diameter of the pipeline.
The inner surface of the end part of the first telescopic device is fixed with the end part of the radial telescopic section of the second telescopic device; the first axial telescopic body comprises a middle short pipe and two first axial telescopic sections, the two first axial telescopic sections and the middle short pipe are of an integrated structure, are similar to a double-wall corrugated pipe in shape and are of a cavity structure with elasticity in the axial direction; the first telescopic device can only axially extend and retract; after the second expansion device expands and contracts axially, the radial expansion body at the end part expands and contracts radially.
The second axial telescopic body comprises a horizontal pipe and two second axial telescopic sections and is also of a corrugated pipe structure, and the radial telescopic body comprises a vertical pipe communicated with the horizontal pipe and telescopic corrugated structures arranged at two ends of the vertical pipe.
The rubber sealing ring is arranged at the end part of the first telescopic device, so that the inner surface of the rubber sealing ring is ensured to be attached to the outer surface of the end part of the first telescopic device; the outer diameter of the end part of the rubber sealing ring is slightly smaller than the inner diameter of the pipeline. Before the connector is launched, the ball locking device is placed in the locking groove of the end cover sleeve.
The working process of the invention is as follows:
before the connector is launched, air in the first axial telescopic body 6 is extracted from the first valve 7 for the first telescopic device 1 and the second telescopic device 2 according to pre-calculated pressure values, air in the second axial telescopic body 8 and air in the radial telescopic body 9 are extracted from the second valve 10 to form negative pressure, then the first axial telescopic body 6 in the first telescopic device 1 and the second axial telescopic body 8 in the second telescopic device 2 are contracted, meanwhile, the radial telescopic body 9 slightly contracts along the radial direction of the first telescopic device 1, so that ports on two sides of the first telescopic device 1 slightly radially expand and contract, and after the process is completed, the telescopic devices can be placed between the two end cover sleeves 12 without contact.
As shown in fig. 2, the frame 3 is first submerged to a predetermined position on the water bottom, and the end cover sleeves 12 on both sides of the frame 3 are respectively installed coaxially with the pipes 13 on both sides. Then submerging the expansion device to a pre-installation position (as shown in figure 3), wherein the external seawater pressure is far higher than the pressure inside the expansion body, the first expansion device 1 and the second expansion device 2 are in a compression state at the moment, the first valve 7 and the second valve 10 are opened, seawater enters the expansion body through the first valve 7 and the second valve 10 under the action of pressure difference, the first expansion device 1 and the second expansion device 2 axially extend, and after the end part of the first expansion device 1 is contacted with the ball head locking device 5, the ball head locking device 5 moves upwards along with the axial movement of the first expansion device 1. As shown in fig. 4, when the first telescopic device 1 extends to the end face of the rubber sealing ring 4 to contact with the end of the pipeline, the ball head locking device 5 is aligned with the locking groove of the first telescopic device 1 and moves downwards to complete locking.
Closing the first valve 7, and stopping the axial extension of the first telescopic device 1; at the moment, the outer surface of the rubber sealing ring 4 is attached to the inner surface of the end cover sleeve 12; under the radial extension of the radial telescopic body 9, the extrusion rubber sealing ring 4 deforms to form an effective sealing environment with the end cover sleeve 12 and the first telescopic device 1, and the second valve 10 is closed to realize sealing.
In summary, the invention provides a telescopic submarine pipeline connector, which comprises a first telescopic device, a second telescopic device, a frame, a ball head locking device and a rubber sealing ring. The working principle is that air in the expansion device is extracted before the connector is launched to form a negative pressure expansion device to be further contracted, after the connector is launched, the valve is opened, seawater enters the expansion device under the action of pressure difference, and the expansion device is expanded to finally realize the connection of the pipeline and the connector. The invention adopts semi-rigid connection, reasonably utilizes seawater energy, reduces the cost of submarine pipeline connection, and is a novel submarine pipeline connector with a very promising prospect.
