Description

Technical Field

[0001] This utility model belongs to the field of oil and gas storage and transportation technology, and specifically relates to an oil and gas storage and transportation protection device. Background Technology

[0002] As a vital mode of transportation, railway transport has carried a significant volume of passenger and freight traffic in modern human society. Simultaneously, in the process of rapid industrialization, not only is efficient electrified railway transport required, but also efficient pipeline transport. Electrified railways and metal pipelines often coexist in parallel or intersecting configurations. Electrified railways use high-voltage power lines to convert electricity into driving force, guiding locomotives on the tracks. Because high-voltage current inherently possesses a magnetic field, and metal pipelines, as conductors, experience electromagnetic induction when passing through this magnetic field, forming a stray current in the form of alternating current, typically recorded as induced voltage. This stray current causes alternating current corrosion of the pipeline.

[0003] Especially when a train passes over the track, the train itself acts as a carrier, constantly cutting through the magnetic field, which causes a sudden increase in induced voltage. This means that the AC interference voltage in the pipeline is too high, and the AC stray current can break down the insulation layer of the metal pipeline, even endangering the operators. At the same time, as the locomotive passes by at high speed, it also generates instantaneous pressure on the ground, increasing the stress on the ground and posing a risk of squeezing and damaging the side pipelines. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes an oil and gas storage and operation protection device, which includes: a base and a metal sleeve. The base has a through cavity for receiving the pipe body. Both ends of the base are embedded with a connecting ring and a conductive ring arranged coaxially with the through cavity. The outer wall of the connecting ring is coaxially sleeved with a metal sleeve for wrapping the pipe. The end of the metal sleeve that is sleeved with the connecting ring abuts against the conductive ring, and a predetermined distance is maintained between the inner wall of the metal sleeve and the inner wall of the pipe.

[0005] The lower end face of the base is provided with a grounding probe, and the base is embedded with a wire that connects the grounding probe and the conductive coil.

[0006] As a further optimization of the above scheme, both ends of the metal sleeve are provided with several end blocks arranged in a circular array, and the conductive ring is provided with several grooves that are adapted to the end blocks.

[0007] Furthermore, the base has an isosceles trapezoidal cross-section.

[0008] Furthermore, the base includes a base and a cover arranged vertically, and the connecting surface of the base and the cover includes a first horizontal surface, an inwardly inclined surface, and a second horizontal surface.

[0009] Furthermore, it also includes an insulating ring sleeve, which is filled between the outer wall of the metal sleeve and the inner wall of the pipe.

[0010] Furthermore, the metal sleeve and the connecting ring are connected by a one-way sawtooth thread.

[0011] Furthermore, the lower end face of the base is provided with several positioning protrusions.

[0012] Compared with the prior art, the embodiments of this utility model have at least the following advantages:

[0013] This utility model discloses an oil and gas storage and operation protection device. A base is fitted to the connection point of two pipelines, and a metal sleeve is used to enclose the pipelines. In addition to a conductive ring and a grounding probe, the metal sleeve acts as a barrier. When the magnetic field in the electrified railway induces electromagnetic current in the metal sleeve, the stray current generated on the sleeve is transmitted to the ground through the conductive ring, guide, and grounding probe, preventing the pipeline insulation layer from being broken down by the current. This achieves electromagnetic protection and drainage protection. Simultaneously, the addition of the sleeve reduces the direct pressure of the ground on the pipeline, further protecting it and extending its service life.

[0014] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained through the structures pointed out in the description and the accompanying drawings. Attached Figure Description

[0018] Figure 3 A cross-sectional schematic diagram of the oil and gas storage and protection device in an embodiment of this utility model is shown.

[0019] In the figure, there are: base 1, base 101, cover 102, metal sleeve 2, connecting ring 3, conductive ring 4, grounding probe 5, end block 6, groove 7, insulating ring 8, and positioning protrusion 9. Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] This utility model provides a protective device for oil and gas storage and operation. Figure 1 A schematic diagram of the oil and gas storage and operation protection device in an embodiment of this utility model is shown. Figure 1 In the oil and gas storage and protection device, there are: a base 1 and a metal sleeve 2. The base 1 has a through cavity for receiving the pipe body. Both ends of the base 1 are fitted with a connecting ring 3 and a conductive ring 4 arranged coaxially with the through cavity. The outer wall of the connecting ring 3 is coaxially sleeved with the metal sleeve 2 for wrapping the pipe. The end of the metal sleeve 2 that is sleeved with the connecting ring 3 abuts against the conductive ring 4. A predetermined distance is maintained between the inner wall of the metal sleeve 2 and the inner wall of the pipe.

[0022] The base 1 has a grounding probe 5 on its lower end face, and the base 1 is embedded with a wire that connects the grounding probe 5 and the conductive ring 4.

[0023] In practical use, this application uses a base 1 connected to the connection point of two pipes, and a metal sleeve 2 to wrap the pipes. Based on the conductive ring 4 and grounding probe 5, the metal sleeve 2 acts as a barrier for protection. When the magnetic field in the electrified railway induces electromagnetic current in the metal sleeve 2, the stray current generated on the metal sleeve 2 is transmitted to the ground through the conductive ring 4, guide, and grounding probe 5, preventing the pipe insulation layer from being broken down by the current, thus achieving electromagnetic protection and drainage protection. At the same time, by adding the sleeve 2, the pressure of the ground directly on the pipe is reduced, further protecting the pipe and improving its service life.

[0024] Specifically, both ends of the metal sleeve 2 are provided with several end blocks 6 arranged in a circular array, and the conductive ring 4 is provided with several grooves 7 that are adapted to the end blocks 6. Figure 1In the example shown, the cross-sections of several end blocks 6 and grooves 7 are tapered to facilitate a stable fit between the metal sleeve 2 and the conductive ring 4. At the same time, the end blocks 6 and grooves 7 improve the current transmission on the metal sleeve 2, thereby enhancing the protection effectiveness of the pipeline.

[0025] refer to Figure 2 In this embodiment, the cross-section of the base 1 adopts an isosceles trapezoidal structure. The structure is narrow at the top and wide at the bottom, so that the base 1 has an inclined side. When the upper end of the device of this application is subjected to pressure, the pressure from top to bottom will be squeezed to the sides and down in the guiding direction of the structure, decomposing the vertical downward force, so as to reduce the force borne by the base 1, thereby increasing the upper limit of the force borne by the base 1 of this application.

[0026] Meanwhile, considering the convenience of using the base 1 in this application, the base 1 includes a base 101 and a cover 102, with the base 101 and the cover 102 arranged vertically. Figure 2 In the example shown, the connecting surfaces of the base 101 and the cover 102 include a first horizontal surface, an inwardly inclined surface, and a second horizontal surface. Through the design of the first horizontal surface, the inwardly inclined surface, and the second horizontal surface, when the cover 102 is subjected to downward or lateral forces, the possibility of misalignment between the base 101 and the cover 102 is directly avoided based on the inwardly inclined surface, and the degree of fit between the base 101 and the cover 102 during assembly is also ensured. Furthermore, based on the fact that the cross-section of the base 1 is an isosceles trapezoid, the force decomposition effect of the base 101 on the cover 102 is further guaranteed.

[0027] refer to Figure 3 It also includes an insulating ring 8, which fills the annular space between the outer wall of the metal sleeve 2 and the inner wall of the pipe. The insulating ring 8 is preferably made of insulating rubber. The insulating ring 8 provides support between the metal sleeve 2 and the pipe, providing force support for the pipe. At the same time, the insulating ring 8 can also buffer the external forces on the metal sleeve 2, further protecting the pipe and reducing the impact of external environmental vibrations on the pipe.

[0028] Specifically, the outer wall of the metal sleeve 2 is provided with a one-way sawtooth thread, and the inner wall of the end of the connecting ring 3 is provided with a one-way sawtooth thread that is compatible with the metal sleeve 2, so as to improve the convenience of the assembly process of the metal sleeve 2 and the connecting ring 3. After the metal sleeve 2 and the connecting ring 3 are assembled, under the action of the one-way sawtooth thread, the connecting ring 3 generates a squeezing force on the conductive ring 4, further ensuring the firmness of the connection between the connecting ring 3 and the conductive ring 4.

[0029] In this embodiment, the lower end face of the base 101 is provided with a plurality of positioning protrusions 9. By inserting the positioning protrusions 9 into the soil or concrete layer to be installed, the overall stability of the device of this application is improved, and the problem of lateral displacement of the device is avoided.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
