Description

Technical Field

[0001] The invention relates to the field of pipeline protection devices, and in particular to an oil and gas pipeline protection device. Background Art

[0002] Oil and gas resources are widely used in the production and life of society. Due to the special nature of their resources, they are mainly transported by pipelines. Most pipelines are laid underground to reduce the possibility of pipeline damage. However, when there are operations in some necessary construction areas around the pipelines, the pipelines are easily damaged, causing unnecessary economic losses.

[0003] At present, most pipeline protection devices have complex structures and need to be laid at the same time as the pipeline in the early stage of pipeline construction. They are difficult to install and most of them lack the function of early warning. Considering that the top of the pipeline is most likely to be damaged, it focuses on multi-layer protection above the pipeline. It is used for the protection of laid pipelines or temporary pipelines. It has a wider range of applications and can promptly remind the force by colored smoke. Multiple measures can have a good protection effect on the pipeline. Summary of the invention

[0004] In order to overcome the concealment of buried pipelines and the complexity and limitations of current pipeline protection devices, the present invention provides an oil and gas pipeline protection device.

[0005] The technical solution adopted by the present invention is: an oil and gas pipeline protection device, which is mainly composed of a pipeline, a protection device body, a spring part, a rubber sheet, a plastic square box, and a bolt, wherein the protection device body is welded by a lower support leg, a diagonal brace, and an upper circular steel pipe and a steel mesh. The circular steel pipe is welded in a grid shape, and the plastic square box is stuck in its grid. The steel mesh is welded to the upper and lower surfaces of the circular steel pipe to fix the plastic square box. The upper periphery and the bottom surface of the protection device body are sealed and welded with thin steel plates. The rubber sheet and the spring part are successively located at the lower part of the circular steel pipe, and the bottom edge of the spring part is welded to the bottom thin steel plate of the upper part of the protection device body. The pipeline protection device is fixed to the pipeline by the bolts on the support legs. When an external force acts on the pipeline, the circular steel pipe and the steel mesh will offset part of the external force, and the spring part and the rubber sheet directly below it can also reduce part of the impact force. At the same time, the colored smoke inside the plastic square box will overflow to remind the construction workers.

[0006] As a preferred embodiment, the plastic square box is filled with colored smoke, which is distributed in all grids welded with the round steel pipe to remind construction workers that there is a pipeline laying here;

[0007] Preferably, the circular steel pipe is welded into a 20cm*20cm mesh structure using a square hollow structure with a cross-sectional shape of 5cm and 6cm, and anti-corrosion treatment is adopted;

[0008] Preferably, the steel wire mesh is made of a structure with a radius of 0.5 mm and a gap of 1 cm*1 cm, and is subjected to anti-corrosion treatment;

[0009] Preferably, the bottom edge of the spring member is welded to the bottom thin steel plate of the upper part of the protective device body, and multiple spring members are evenly distributed, and the steel material of the spring member and the protective device body is subjected to anti-corrosion treatment;

[0010] The present invention is an oil and gas pipeline protection device, which has the following beneficial effects:

[0011] (1) It can be used to protect laid pipelines or temporary pipelines, is easy to install, and has a wider range of applications;

[0012] (2) The plastic box is filled with colored smoke, which has a warning effect after being destroyed. The protective device uses a circular steel pipe, a steel mesh, a spring and a rubber sheet from top to bottom to reduce the external impact force, and can provide multi-layer protection; BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described below in conjunction with the accompanying drawings

[0018] As shown in the figure, an oil and gas pipeline protection device of the present invention is mainly composed of a pipeline 1, a protection device body 2, a spring member 3, a rubber sheet 4, a plastic square box 5, and a bolt 6. The protection device body 2 is welded by a lower support leg 21, a diagonal support rod 22, and an upper circular steel pipe 24 and a steel mesh 23. The circular steel pipe 24 is welded in a grid shape, and the plastic square box 5 is stuck in the grid of the circular steel pipe 24. The steel mesh 23 is welded to the upper and lower surfaces of the circular steel pipe 24 to fix the plastic square box 5. The upper four sides and the bottom surface of the protection device body 2 are sealed and welded with thin steel plates. The rubber sheet 4 and the spring member 3 are sequentially located at the lower part of the circular steel pipe 24, and the bottom edge of the spring member 3 is welded to the bottom thin steel plate of the upper part of the protection device body 2. The pipeline protection device is fixed to the pipeline 1 by the bolts 6 on the support leg 21.

[0019] When the present invention is used to protect the oil and gas pipeline, the following steps are included:

[0020] (1) If used for the protection of newly laid pipelines, transport the components of the pipeline protection device to the designated location, lower the pipeline to the bottom of the trench, ensure that the pipeline is stable, place the pipeline protection device above the pipeline, ensure that the support legs are evenly stressed, and then fix the pipeline protection device to the pipeline with bolts;

[0021] (2) If used to protect an already operating pipeline, transport the components of the pipeline protection device to the designated location, excavate the pipeline until the upper half is exposed, place the pipeline protection device on top of the pipeline, ensure that the support legs are evenly stressed, and then fix the pipeline protection device to the pipeline with bolts;

[0022] (3) If used for temporary pipeline protection, transport the components of the pipeline protection device to the designated location, place the pipeline protection device on top of the pipeline, ensure that the support legs are evenly stressed, and then fix the pipeline protection device to the pipeline with bolts. When the protection needs to be released, remove the bolts and retract the protection device.

[0023] When the present invention is used to protect oil and gas pipelines, when a small object acts on the pipeline, the uppermost steel wire mesh can offset part of the external force; when a large object acts on the pipeline, the uppermost circular steel pipe and steel wire mesh can offset part of the external force; at the same time, the rubber sheet and spring member directly below the circular steel pipe can also offset part of the external force; when the plastic square box is damaged, colored smoke in its inner cavity overflows to serve as a warning; multi-layer protection and early warning can be performed; and it can be used for the protection of laid pipelines or temporary pipelines, with a wider range of applications.
