Abstract
The utility model relates to a pipeline vortex-induced vibration fairing, and belongs to the technical field of pipelines. The pipeline vortex-induced vibration fairing comprises a V-shaped fairing body and two semi-circular grooves which are the same in shape. The V-shaped fairing body is formed by enabling two faces to intersect. Radial reinforcing plates are arranged on the two sides in the axial direction of each semi-circular groove. The radial reinforcing plates on one side of the two semi-circular grooves are fixedly connected so as to form a cylindrical sleeve, each semi-circular groove is connected with the non-intersecting edges of one face of the V-shaped fairing body, and then a part of the sleeve is embedded into a cavity formed by the V-shaped fairing body. The sleeve is formed by the two semi-circular grooves and can be separated at a contacting face, all the parts of the pipeline vortex-induced vibration fairing are connected into a whole, therefore, butt joint and locking are not needed in the installation process, and good installation performance is achieved.
Description
Technical field
The utility model relates to a kind of pipeline vortex-induced vibration cowling, belongs to pipe technology field.
Background technique
Key in herein background technique and describe in the Application and Development that paragraph pipeline is widely used in offshore oil and rock gas, the vortex-induced vibration for avoiding ocean current to cause sometimes, conventionally can additional cowling.Pipeline vortex-induced vibration cowling adopts rear opening mostly at present, and installation steps are loaded down with trivial details and time-consuming.Therefore, be necessary this to improve, a kind of improvement of model utility, the pipeline vortex-induced vibration cowling of good installation had.
Summary of the invention
The loaded down with trivial details shortcoming of installation steps existing for overcoming existing pipeline vortex-induced vibration cowling, goal of the invention of the present utility model is to provide a kind of pipeline vortex-induced vibration cowling that has good installation, described pipeline vortex-induced vibration cowling is installed simple, without other setting tool and installation accessories, can be single or underwater robot install, have good installation.
For realizing goal of the invention of the present utility model, the utility model provides a kind of pipeline vortex-induced vibration cowling, and it comprises two half slots that V-type cowling is identical with shape; Wherein V-type cowling is intersected by two faces and forms; Each half slot both sides are vertically provided with strengthens footpath plate; Two half slots reinforcement footpath plate is on one side fixedly connected with to form a cylindrical sleeve, and each half slot connects with the not crossing limit of a face of V-type cowling, so makes in cavity that part sleeve embedding V-type cowling forms.
Preferably, two tops of each half slot are along being circumferentially provided with semicircle annular support ring; The outer wall of each half slot is provided with one or more draw rings vertically.
Preferably, the one or more draw rings of outer installment of two faces of V-type cowling, the height of each face length degree sleeve of V-type cowling is identical, and width is 1 to 10 times of sleeve outer diameter.
Preferably, two of V-type cowling faces are plane or flexure plane.
Preferably, there are one or more local thickened portions the inside of two of V-type cowling faces.
Compared with prior art, pipeline vortex-induced vibration cowling provided by the utility model adopts preposition open type layout, only need pull open sleeve during installation, and pipeline vortex-induced vibration cowling is enclosed within to pipeline external, unclamps sleeve, completes installation.Pipeline vortex-induced vibration cowling adopts integral type design, and installation process is without docking and locking, also without loose mail.Thereby there is a good installation.
Accompanying drawing explanation
Fig. 1 is the front schematic view of the pipeline vortex-induced vibration cowling that provides of the utility model;
Fig. 2 is side diagram in the three-dimensional of the pipeline vortex-induced vibration cowling that provides of the utility model;
Fig. 3 is side diagram before the three-dimensional of the pipeline vortex-induced vibration cowling that provides of the utility model.
Embodiment
Below in conjunction with accompanying drawing, describe the utility model in detail, identical reference character represents identical parts.
Fig. 1 is the front schematic view of the pipeline vortex-induced vibration cowling that provides of the utility model.As shown in Figure 1, the pipeline vortex-induced vibration cowling that the utility model provides comprises two half slots that V-type cowling 1 is identical with shape; Wherein V-type cowling is intersected by two faces and forms; Each half slot both sides are vertically provided with strengthens footpath plate 2; The reinforcement footpath plate on two half slot one side is fixedly connected with to form a cylindrical sleeve 3, and the reinforcement footpath plate of another side does not connect to form to close puts opening 4; The not crossing limit of a face of each half slot and V-type cowling connects, and so makes part sleeve embed in the cavity that V-type cowling forms.
Two tops of each half slot are along being circumferentially provided with semicircle annular support ring, and when two half slots are fixed together formation sleeve, support ring 5 on upper end forms, forms lower support ring 6 in lower end; The outer wall of each half slot is provided with one or more draw rings 7 and 8 vertically.
The outside of two faces of V-type cowling all arranges two draw rings 9 and 10, and the height of each face length degree sleeve of V-type cowling is identical, and width is 1 to 10 times of sleeve outer diameter.Two faces of V-type cowling are plane or flexure plane.There are one or more local thickened portions the inside of two faces of V-type cowling.
Fig. 2 is side diagram in the three-dimensional of the pipeline vortex-induced vibration cowling that provides of the utility model.Fig. 3 is side diagram before the three-dimensional of the pipeline vortex-induced vibration cowling that provides of the utility model.As shown in Figure 3, the outer wall of a half slot is provided with two draw rings 7 and 8 vertically.The periphery of another half slot is provided with two draw rings 11 and 12 vertically.
Pipeline vortex-induced vibration cowling provided by the utility model adopts preposition open type layout, only need pull open sleeve during installation, and pipeline vortex-induced vibration cowling is enclosed within to pipeline external, unclamps sleeve, completes installation.Pipeline vortex-induced vibration cowling adopts integral type design, and installation process is without docking and locking, also without loose mail.Thereby there is a good installation.
More than being described with reference to the accompanying drawings the utility model, is only for explaining claims but those of ordinary skills it should be known that specification.But protection domain of the present utility model is not limited to specification.In the technical scope that any those skilled in the art of being familiar with disclose at the utility model, the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
