Description

Technical Field

[0001] This invention relates to the field of pipeline protection, and in particular to a device and method for preventing third-party damage to gas transmission pipelines. Background Technology

[0002] Natural gas long-distance pipelines are distributed across vast areas. Due to local economic development, third-party construction is inevitable around these pipelines. The use of machinery and heavy transport vehicles during these construction processes can damage the anti-corrosion layer of the pipelines and crush exposed pipe sections, posing certain risks to the safe operation of the natural gas pipelines. In recent years, in particular, with the accelerated pace of urban construction and the renovation of old residential areas in county towns, more and more areas need to be rebuilt. During this reconstruction, gas pipelines inevitably need to be dug up and exposed. The reckless construction by some construction companies has led to repeated cases of gas pipeline damage caused by third-party construction. This not only results in pipeline damage and gas leaks, but in severe cases, it can also cause large-scale gas outages, causing inconvenience to citizens and posing a great risk to urban safety. According to statistics from August 2023, a certain gas company had carried out 129 pipeline maintenance and repair operations near the Sichuan-West pipeline caused by third-party construction. The large amount of pipeline maintenance work also increases pipeline maintenance costs.

[0003] The current conventional method of using warning tape to indicate and protect exposed pipe sections is prone to damage, which makes it impossible to guarantee the safety of exposed pipe sections. Other fixed gas pipeline protection devices, such as brick box culverts and steel sleeves, have long production cycles, and steel sleeves need to be pre-prepared into an assembly shell that fits the shape of the pipeline. They cannot quickly adapt to the protection of gas pipelines of different diameters and lengths. Moreover, they are bulky, making installation, disassembly and transportation inconvenient and affecting the efficiency of gas pipeline maintenance.

[0004] Therefore, there is an urgent need for a technical solution to address the problem that exposed sections of existing gas pipelines cannot be protected quickly and effectively, making them vulnerable to damage from third-party construction and affecting the safe operation of gas pipelines. Summary of the Invention

[0005] The purpose of this invention is to address the technical problem that exposed sections of existing gas pipelines cannot be quickly and effectively protected, making them susceptible to damage from third-party construction and affecting the safe operation of gas pipelines. This invention provides a device and method for preventing third-party damage to gas pipelines.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A device for preventing third-party damage to a gas pipeline includes at least two end components. Each end component includes an inner ring component and an outer ring component. The inner ring component is capable of being held onto the pipeline. The outer ring component includes a first half-ring component and a second half-ring component that are connected in a butt joint. A plurality of radial baffles are connected between the inner ring component and the outer ring component. A plurality of the end components are arranged in a plurality of ways. A plurality of axial baffles are connected between longitudinally adjacent outer ring components. A plurality of axial baffles are connected between longitudinally adjacent inner ring components. A color layer is provided on the outer surface of the inner ring component, the outer ring component, the radial baffles, and the axial baffles.

[0008] This invention discloses a device for preventing third-party damage to gas pipelines. It comprises an inner ring component, an outer ring component, radial baffles, and axial baffles forming a cage-like structure. This cage-like structure holds the pipeline in place on exposed pipe sections, providing segmental protection and preventing damage caused by direct contact with the pipeline during third-party construction. Simultaneously, a color layer provides clear identification for third-party construction personnel, preventing pipeline damage due to misoperation. This achieves effective pipeline protection. Compared to conventional warning tapes, the device is less prone to damage and provides stable protection. Compared to conventional fixed protective devices, it has a simple structure, can be assembled on-site, and is easy to install, disassemble, and carry.

[0009] In a preferred embodiment of the present invention, the inner ring component and the outer ring component are provided with connecting holes, connecting posts, or sliding grooves for connecting the axial stop bars; the inner ring component and the outer ring component are provided with connecting holes, connecting posts, or sliding grooves for connecting the radial stop bars. This enables detachable connection of the radial and axial stop bars, allowing the device to be adapted for on-site assembly and improving its portability.

[0010] In a preferred embodiment of the present invention, the radial and axial stops are provided with length adjustment parts. The radial and axial stops include plates or columns, and are provided with scales for indicating length. This allows for adaptive adjustment of the device's structural dimensions according to the pipe size via the length adjustment parts and scales. Furthermore, the plate or column radial and axial stops have a simple structure, are small in size, and are easy to carry. During use, the length of each radial and axial stop can be adjusted according to the scales.

[0011] In a preferred embodiment of the present invention, the outer ring component and the inner ring component each comprise a plate, the surface of which is perpendicular to the pipe axis. An arc-shaped tube segment is disposed on the side of the inner ring component closest to the pipe, and this arc-shaped tube segment is used to abut against the pipe. The outer and inner ring components of the plate are relatively thin, resulting in a small overall size of the device and easy portability. The inner ring component fits snugly against the pipe via the arc-shaped tube segment, ensuring a stable fit between the device and the pipe, thus achieving stable installation of the device on the pipe.

[0012] In a preferred embodiment of the present invention, the inner ring component includes at least two inner ring plates, each of which is connected to the arc-shaped pipe segment. A buffer mechanism is provided on the inner arc surface of the arc-shaped pipe segment. Multiple inner ring plates are combined to form the inner ring component, allowing the inner ring component to easily conform to the outer surface of pipes of different dimensions, thus enabling smooth and quick installation of the device.

[0013] In a preferred embodiment of the present invention, the radial baffle is provided with a joint portion, the joint portion including a first hinge portion and a second hinge portion that are hinged together, and the first hinge portion and the second hinge portion are connected to an elastic mechanism. This enables the device to have a certain resistance to deformation when subjected to external pressure, thus blocking the pipeline and providing a good protective effect.

[0014] In a preferred embodiment of the present invention, a warning mechanism is embedded in the outer ring component. The warning mechanism includes a light strip or indicator light and is connected to a control mechanism. This further enhances the warning effect of the device through the light strip or indicator light.

[0015] As a preferred embodiment of the present invention, a reflective strip is provided on the axial stop bar connecting the inner ring component. This reflects the light to further enhance the warning effect of the device.

[0016] As a preferred embodiment of the present invention, the color layer includes a luminescent material coating layer to improve the warning effect of the device in construction sites with poor lighting.

[0017] A method for preventing third-party damage to a gas pipeline, employing the device described above, includes the following steps: S1, determining the size of the outer ring component based on the outer diameter of the pipeline, wherein the diameter of the outer ring component is at least twice the diameter of the pipeline; S2, adjusting the inner ring component to fit the pipeline; S3, connecting the inner ring component and the outer ring component via radial baffles to form the end component; S4, connecting longitudinally adjacent inner ring components via axial baffles; S5, connecting longitudinally adjacent outer ring components via axial baffles to form the device.

[0018] The present invention provides a method for preventing third-party damage to gas pipelines. By employing the aforementioned device, the pipeline is provided with stable protection. The device is easy to install, disassemble, and carry, and can complete the protection of exposed pipelines in the shortest possible time, thereby improving the protection effect and preventing pipeline damage from third-party construction.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the gas pipeline protection device for third-party damage according to the present invention are:

[0020] 1. A squirrel cage structure is formed by combining inner ring components, outer ring components, radial baffles and axial baffles. This squirrel cage structure is used to hold the exposed pipe section, providing segmental protection for the pipeline and avoiding damage to the pipeline caused by direct contact with the pipeline by third-party construction.

[0021] 2. By using color-coded layers to provide clear identification for third-party construction personnel, pipe damage caused by misoperation can be avoided, thus achieving effective protection of the pipes;

[0022] 3. Compared to conventional warning tapes, the device is not easily damaged and can provide a stable protective effect;

[0023] 4. Compared with conventional fixed protective devices, it has a simple structure, can be assembled on site, and is easy to install, disassemble and carry;

Detailed Implementation

[0037] The present invention will now be described in detail with reference to the accompanying drawings.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0039] Example 1

[0040] like Figures 1-5 As shown, this embodiment of a gas pipeline protection device against third-party damage includes two end components 1. Each end component 1 includes an inner ring component 2 and an outer ring component 3. Both the outer ring component 3 and the inner ring component 2 are plates, preferably steel plates. In use, the plate surface is perpendicular to the axis of the pipeline 10. The inner ring component 2 can be held onto the pipeline 10. The outer ring component 3 includes a first half-ring component 31 and a second half-ring component 32 connected by a butt joint. Multiple radial baffles 4 are provided between the inner ring component 2 and the outer ring component 3. The two end components 1 are arranged longitudinally and parallel to each other. Multiple axial baffles 5 are connected between the outer ring components 3 and between the inner ring components 2. The inner ring component 2, outer ring component 3, radial baffles 4 and axial baffles 5 are combined to form a cage-like structure. The outer surfaces of the inner ring component 2, outer ring component 3, radial baffles 4 and axial baffles 5 are provided with a color layer.

[0041] This embodiment provides a device for preventing third-party damage to a gas pipeline. Both radial baffles 4 and axial baffles 5 are evenly distributed around the inner ring component 2, forming a cage-like structure. In use, as... Figure 5As shown, the inner ring component 2 is clamped onto the exposed pipe section, realizing the installation of the device on the pipe 10. The cage-like device protects the pipe 10 section, preventing damage to the pipe 10 caused by direct contact with the pipe 10 during third-party construction. At the same time, the color layer provides a conspicuous identification for third-party construction personnel, preventing damage to the pipe 10 caused by misoperation, thus achieving effective protection for the pipe 10. Compared with conventional warning tapes, the device is not easily damaged and can provide a stable protective effect. Compared with conventional fixed protective devices, it has a simple structure, can be assembled on site, and is easy to install, disassemble, and carry.

[0042] Preferably, the color layer includes a luminescent material coating. This allows the device to provide a certain level of warning even in low-light conditions such as nighttime construction, thus ensuring continuous protection of the pipeline 10.

[0043] In this embodiment, as Figure 1 As shown, preferably, both the inner ring component 2 and the outer ring component 3 are annular components composed of two half-ring components. That is, the outer ring component 3 is formed by connecting the first half-ring component 31 and the second half-ring component 32 to form an annular component, and the inner ring component 2 is formed by connecting two inner ring plates 21 to form an annular component. The two inner ring plates 21 are respectively connected to the first half-ring component 31 and the second half-ring component 32 by radial baffles 4 to form a whole, forming a squirrel cage structure that can be formed by assembling the two parts to form a channel that matches the shape of the pipe 10. This facilitates the rapid installation of the device on site. The assembly of the two parts can be achieved by bolts passing through appropriate positions according to the actual situation.

[0044] In this embodiment, as Figure 4 As shown, the outer ring component 3 serves as the outermost protective layer of the pipe 10. It is composed of a first half-ring component 31 and a second half-ring component 32, which reduces the number of connection points on the outer ring component 3. This helps to ensure the strength of the outer ring component 3 while ensuring its rapid installation. The inner ring component 2 can be configured as two or more inner ring plates 21 combined according to the actual situation. This allows the inner ring component 2 to adjust the spacing between adjacent inner ring plates 21 according to the length of the radial baffle 4, thereby adapting to pipes 10 with different diameters and enabling the device to quickly adapt to assembly and use on different pipe diameters.

[0045] Furthermore, since the inner ring plate 21 in this embodiment is made of a plate and is relatively thin, it is preferable to connect an arc-shaped tube piece 22 to the side of each inner ring plate 21 near the pipe 10. The arc-shaped tube piece 22 is used to abut against the pipe 10. A buffer mechanism 23 is provided on the inner arc surface of the arc-shaped tube piece 22 to increase the contact area between the device and the pipe 10 and improve the installation stability of the device on the pipe 10. The buffer mechanism 23 can be optionally set as a rubber pad or a rubber block connected with a spring.

[0046] In some embodiments, the radial baffle 4 is welded to the inner ring member 2 and the outer ring member 3 to improve the overall integrity of the device and facilitate rapid assembly on the field pipeline 10.

[0047] In some embodiments, the inner ring component 2 and the outer ring component 3 are provided with connecting holes, connecting posts, or sliding grooves for connecting the axial stop bar 5; the inner ring component 2 and the outer ring component 3 are provided with connecting holes, connecting posts, or sliding grooves for connecting the radial stop bar 4. That is, by adjusting the connection method at both ends of the radial stop bar 4 and the axial stop bar 5, a detachable connection of the radial stop bar 4 and the axial stop bar 5 can be achieved, simplifying the device and making it easier to carry. This allows for adaptive assembly of the device on-site, improving its portability.

[0048] Specifically, when connecting holes are provided on the inner ring component 2 and the outer ring component 3, the inner ring component 2 and the outer ring component 3 have sufficient thickness to accommodate connecting holes in two directions. The radial baffle 4 and the axial baffle 5 are preferably made of columns, and both ends of the radial baffle 4 and the axial baffle 5 can extend into the connecting holes to achieve connection. When connecting columns are provided on the inner ring component 2 and the outer ring component 3, the inner ring component 2 and the outer ring component 3 have sufficient thickness to accommodate connecting columns in two directions. The radial baffle 4 and the axial baffle 5 are preferably made of plates, and the ends of the radial baffle 4 and the axial baffle 5 of the plates are bent to create hole structures, which are then adapted to the connecting columns. This enables connection; when grooves are provided on the inner ring component 2 and the outer ring component 3, the inner ring component 2 and the outer ring component 3 have the thickness to satisfy the setting of grooves in two directions. The two ends of the inner ring component 2 and the outer ring component 3 extend into the grooves and are slidably set in the grooves to achieve connection. At this time, since the radial baffle 4 and the axial baffle 5 can slide according to the actual situation, the number of radial baffle 4 and the axial baffle 5 can be adjusted according to the actual situation so that the device can adjust the density of the cage-type outer perimeter barrier on site according to the environment of the pipeline 10, thereby expanding the adaptability of the device and realizing the smooth and quick installation of the device on site.

[0049] Example 2

[0050] like Figures 6-7 As shown in the figure, this embodiment of a gas pipeline protection device against third-party damage, based on embodiment 1, has a length adjustment part 6 provided on the radial baffle 4 and the axial baffle 5. The radial baffle 4 and the axial baffle 5 include a plate or a column, and the radial baffle 4 and the axial baffle 5 are provided with a scale 7 for indicating the length.

[0051] This embodiment provides a device for preventing third-party damage to a gas pipeline, such as... Figure 6As shown, the axial stop bar 5 of the slat is provided with a keyway and a limiting member as an example to illustrate the length adjustment part 6. The axial stop bar 5 consists of two parts, both of which are provided with keyways. The limiting member can move in the keyway and limit the two parts of the axial stop bar 5, so that the axial stop bar 5 has a length adjustment function and can achieve accurate length adjustment according to the scale 7.

[0052] It is understandable that when the axial stop 5 and the radial stop 4 are cylindrical, such as Figure 7 As shown, the column consists of two parts. At the joint of the two parts, one part is connected to the adjusting cylinder, which is provided with an internal threaded hole. The other part is provided with a threaded section. By rotating the threaded section relative to the internal threaded hole, the length adjustment function of the axial stop bar 5 and the radial stop bar 4 can also be realized. This allows the device to adapt to the dimensions of the pipe 10 by adjusting the length of the axial stop bar 5 and the radial stop bar 4. This enables the device to quickly adapt to the structural dimensions of the pipe 10 on site and achieve quick installation of the device.

[0053] Preferably, the radial baffles 4 are provided with ball heads at both ends. The ball heads are slidably disposed in the grooves of the inner ring component 2 and the outer ring component 3. Under normal use, the length of the radial baffles 4 is adjusted so that the ball heads abut against the inner wall of the groove. When the device is subjected to external pressure, the outer ring component 3 deforms and the ball heads slide along the groove, causing the radial baffles 4 to tilt toward the pipe 10. The radial baffles 4 slide close together and block the pipe 10 and the external pressure-applying component, increasing the distance between the pipe 10 and the external pressure-applying component, and preventing the pressure-applying component from directly contacting the pipe 10, thus achieving a protective effect. In this way, the device can be prevented from being directly flattened under external pressure, which would cause the pressure-applying component to come into close contact with the pipe 10. It also helps to reduce the degree of damage to the device under external pressure and enables it to be recycled and reused.

[0054] Example 3

[0055] like Figure 8 As shown, this embodiment of a gas pipeline protection device against third-party damage, based on embodiment 1, has a radial baffle 4 with a joint 8. The joint 8 includes a first hinge 81 and a second hinge 82 that are hinged together, and the first hinge 81 and the second hinge 82 are connected by an elastic mechanism 83.

[0056] This embodiment of a gas pipeline protection device for third-party damage further defines the radial baffle 4 by providing a joint 8 on the radial baffle 4. The joint 8 is hinged to the two parts of the radial baffle 4 through a first hinge 81 and a second hinge 82. When the device is subjected to external pressure, the radial baffle 4 can bend at the joint 8, and the elastic mechanism 83, such as a spring, provides a bending buffer force to the joint 8, so that the radial baffle 4 can have a buffering effect under the action of external pressure, preventing the external pressure from being directly transmitted to the pipeline 10. After the external pressure disappears, the radial baffle 4 can also have a certain restoring ability under the action of the elastic mechanism 83, so that the device has a certain resistance to deformation and provides good protection for the pipeline 10.

[0057] Example 4

[0058] like Figure 9 As shown, this embodiment of a gas pipeline protection device against third-party damage, based on embodiment 1, has an outer ring component 3 with an embedded warning mechanism 9, the warning mechanism 9 including a light strip, the warning mechanism 9 connected to a control mechanism, and a reflective strip provided on the axial stop bar 5 connected to the inner ring component 2.

[0059] This embodiment of a gas pipeline protection device for third-party damage includes an outer ring component 3 with a light strip as a warning mechanism 9. After the outer ring component 3 is assembled, the light strip is embedded in a groove formed on the outer or inner ring of the outer ring component 3, forming an outer ring component 3 with a lighting effect. The light strip is connected to a control mechanism, which controls the lighting and extinguishing of the light strip. In actual installation, electronic devices are used to achieve remote control or on-site manual control, so that the lighting of the light strip can further improve the warning effect of the device, making it easier for third-party construction personnel to notice the location of the pipeline 10 and avoid damage to the pipeline 10 caused by misoperation.

[0060] Preferably, the light strip can be set with varying lighting according to the actual situation. The light from the light strip is projected onto the reflective strip of the axial baffle 5 of the inner ring component 2, which can improve the marking effect of the pipe 10 and thus improve the warning effect of the device.

[0061] Example 5

[0062] A method for preventing third-party damage to gas pipelines, employing a device for preventing third-party damage to gas pipelines as described in Example 4, includes the following steps:

[0063] S1. Determine the size of the outer ring component 3 according to the outer diameter of the pipe 10. The diameter of the outer ring component 3 is at least twice the diameter of the pipe 10. Specifically, the diameter of the outer ring component 3 is twice the diameter of the pipe 10, so that the outer ring component 3 has a sufficient distance from the pipe 10.

[0064] S2. Adjust the inner ring component 2 to fit with the pipe 10. Specifically, by adjusting the length of the radial baffle 4, the inner ring component 2 is moved relative to the outer ring component 3, so that the inner ring component 2 fits with the pipe 10.

[0065] S3. Connect the inner ring component 2 and the outer ring component 3 through the radial baffle 4 to form the end component 1. Specifically, after determining the length of the radial baffle 4 according to the distance between the inner ring component 2 and the outer ring component 3, install the radial baffle 4. Multiple radial baffles 4 are evenly distributed around the inner ring component 2 to form the end component 1.

[0066] S4. Connect the longitudinally adjacent inner ring components 2 through the axial baffles 5. Specifically, determine the longitudinal length of the device, i.e. the distance between the two end components 1, based on the length of the pipe 10 to be protected, and then determine the length of the axial baffles 5. Connect the inner ring components 2 of the two end components 1 through the axial baffles 5 with the determined length, and each axial baffle 5 is evenly distributed around the pipe 10.

[0067] S5. The device is formed by connecting the longitudinally adjacent outer ring components 3 through axial baffles 5. Specifically, the outer ring components 3 of the two end components 1 are connected by axial baffles 5 of a determined length, and each axial baffle 5 is evenly distributed around the pipe 10.

[0068] This embodiment provides a method for preventing third-party damage to a gas pipeline. By employing the aforementioned device, the pipeline 10 is provided with stable protection. The device is easy to install, disassemble, and carry, and can complete the protection of the exposed pipeline 10 in the shortest possible time, thereby improving the protection effect and preventing the pipeline 10 from being damaged by third-party construction.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
