Description

Technical Field

[0001] The invention relates to the field of pipeline protection, and in particular to a device and method for preventing a gas pipeline from being damaged by a third party. Background Art

Especially in recent years, with the accelerated advancement of urban construction and the governance and renovation of old communities in county towns, more and more areas need to be re-constructed. During re-construction, the gas pipeline will inevitably need to be dug to an exposed state. The barbaric construction of some construction units has led to repeated cases of gas pipeline damage due to third-party construction, which will not only cause pipeline damage and gas leakage, but also cause large-scale gas outages in severe cases, bringing inconvenience to citizens' lives and posing great risks to urban safety. According to statistics in August 2023, a gas unit has carried out 129 pipeline maintenance operations near the Sichuan West Pipeline due to third-party construction.

[0024] In the device for preventing a gas pipeline from being damaged by a third party according to the present embodiment, the radial stop bars 4 and the axial stop bars 5 are evenly distributed around the circumference of the inner ring member 2 to form a squirrel cage structure. Figure 5 As shown, the inner ring member 2 is clamped on the exposed pipe section to achieve clamping of the device on the pipeline 10. The squirrel cage device is used to protect the segment of the pipeline 10, which can avoid damage to the pipeline 10 caused by direct contact with the pipeline 10 by third-party construction. At the same time, the color layer provides a striking mark for third-party construction personnel, which can avoid damage to the pipeline 10 caused by misoperation, thereby achieving effective protection of the pipeline 10. Compared with conventional warning tapes, the device is not easily damaged and can provide a stable protection effect. Compared with conventional fixed protection devices, it has a simple structure and can be assembled on site. It has a simple structure and is easy to install, disassemble and carry.

[0025] Preferably, the color layer includes a luminous material coating layer, so that the device can have a certain warning effect in a construction environment at night with poor light, so as to continuously protect the pipeline 10 through the device.

[0026] In this embodiment, Figure 1 As shown, preferably, both the inner ring member 2 and the outer ring member 3 are annular members composed of two half-ring members, that is, the outer ring member 3 is composed of a first half-ring member 31 and a second half-ring member 32 connected to form an annular member, and the inner ring member 2 is composed of two inner ring plates 21 connected to form an annular member, and the two inner ring plates 21 are respectively connected to the first half-ring member 31 and the second half-ring member 32 through radial strips 4 as a whole, forming a squirrel cage structure in which the two parts can be assembled to form a channel that is compatible with the shape of the pipeline 10, so as to facilitate the rapid installation of the device on site, and the assembly of the two parts can be achieved by bolts passing through appropriate positions according to actual conditions.

[0027] In this embodiment, Figure 4 As shown, the outer ring member 3 plays the role of protecting the outermost part of the pipeline 10, and is composed of a first half ring member 31 and a second half ring member 32, which can reduce the connection positions on the outer ring member 3, and is beneficial to ensure the use strength of the outer ring member 3 on the basis of ensuring the rapid installation of the outer ring member 3. The inner ring member 2 can be set to be combined into more than two inner ring plates 21 according to actual conditions, so that the inner ring member 2 can adjust the distance between adjacent inner ring plates 21 according to the length change of the radial stop bar 4, so as to achieve adaptation with pipelines 10 of different diameters, so that the device can quickly adapt to assembly and use on pipes of different diameters.

[0028] Furthermore, since the inner ring plate 21 in the present embodiment is made of a plate with a relatively thin thickness, it is preferred to connect an arc-shaped tube segment 22 to one side of each inner ring plate 21 close to the pipeline 10. The arc-shaped tube segment 22 is used to abut the pipeline 10. A buffer mechanism 23 is provided on the inner arc surface of the arc-shaped tube segment 22 so that the contact area between the device and the pipeline 10 is increased through the arc-shaped tube segment 22, thereby improving the installation stability of the device on the pipeline 10. The buffer mechanism 23 can be optionally provided as a rubber pad or a rubber block connected to a spring.

[0029] In some embodiments, the radial stop bar 4 is connected to the inner ring member 2 and the outer ring member 3 by welding to improve the integrity of the device and facilitate rapid assembly on the on-site pipeline 10 .

[0030] In some embodiments, the inner ring member 2 and the outer ring member 3 are provided with connection holes, connection columns or slide grooves for connecting the axial stop bar 5; the inner ring member 2 and the outer ring member 3 are provided with connection holes, connection columns or slide grooves for connecting the radial stop bar 4. That is, by adjusting the connection mode of the two ends of the radial stop bar 4 and the axial stop bar 5, the detachable connection of the radial stop bar 4 and the axial stop bar 5 is realized, the whole is broken down into parts, the device is convenient to carry, the device can be adaptively assembled on site, and the portability of the device is improved.

[0031] Specifically, when connecting holes are set on the inner ring component 2 and the outer ring component 3, the inner ring component 2 and the outer ring component 3 have a thickness sufficient for setting connecting holes in two directions, and the radial strips 4 and the axial strips 5 are preferably cylindrical, and the two ends of the radial strips 4 and the axial strips 5 of the cylinder can extend into the connecting holes to achieve connection; when connecting columns are set on the inner ring component 2 and the outer ring component 3, the inner ring component 2 and the outer ring component 3 have a thickness sufficient for setting connecting columns in two directions, and the radial strips 4 and the axial strips 5 are preferably plate parts, and the radial strips 4 and the axial strips 5 of the plate parts are bent at both ends to set hole structures, and are adapted to the connecting columns through the hole structures. Then the connection is achieved; when the slide grooves are set on the inner ring member 2 and the outer ring member 3, the inner ring member 2 and the outer ring member 3 have a thickness that satisfies the setting of the slide grooves in two directions, and the two ends of the inner ring member 2 and the outer ring member 3 extend into the slide grooves, and are set in the slide grooves by sliding the ends, thereby achieving the connection. At this time, since the radial stop bars 4 and the axial stop bars 5 can slide according to actual conditions, the number of radial stop bars 4 and the axial stop bars 5 can be adjusted according to actual conditions, so that the device can perform on-site adjustment of the squirrel cage peripheral barrier density according to the on-site pipeline 10 environment, so as to expand the adaptability of the device and realize the smooth and quick installation of the device on site.

[0032] Example 2 like Figure 6-Figure 7 As shown, a device for preventing a gas pipeline from being damaged by a third party in this embodiment is provided. On the basis of embodiment 1, a length adjustment portion 6 is provided on the radial baffle 4 and the axial baffle 5. The radial baffle 4 and the axial baffle 5 include slats or cylinders. The radial baffle 4 and the axial baffle 5 are provided with a scale 7 for indicating the length.

[0033] A device for preventing a gas pipeline from being damaged by a third party in this embodiment is as follows: Figure 6 As shown, taking the key groove and the limit piece arranged on the axial bar 5 of the slat as the length adjustment part 6 as an example for illustration, the axial bar 5 is composed of two parts, both of which are provided with a key groove, and the limit piece can limit the two parts of the axial bar 5 after moving in the key groove, so that the axial bar 5 has a length adjustment function and can realize accurate length adjustment according to the scale 7.

[0034] It can be understood that when the axial stop bar 5 and the radial stop bar 4 are cylindrical, Figure 7 As shown, the column consists of two parts. At the position where the two parts are connected, one part is connected to the adjusting cylinder, and the adjusting cylinder is provided with an internal threaded hole, and the other part is provided with a threaded section. Through the relative rotation of the threaded section and the internal threaded hole, the length adjustment function of the axial and radial strips 5 and 4 can also be realized, so that the device can adaptively adjust the length of the axial strips 5 and the radial strips 4 according to the size of the pipeline 10, so that the device can quickly adapt to the structural size of the on-site pipeline 10, and realize the quick installation of the device.

[0035] Preferably, ball heads are provided at both ends of the radial stop bar 4, and the ball heads are slidably arranged in the slide grooves of the inner ring component 2 and the outer ring component 3. Under normal use conditions, the length of the radial stop bar 4 is adjusted to make the ball heads abut against the inner wall of the slide groove. When the device is subjected to external pressure, the outer ring component 3 is deformed, and the ball heads will slide along the slide groove, causing the radial stop bar 4 to tilt toward the side of the pipeline 10. The radial stop bars 4 slide together to block between the pipeline 10 and the external pressure component, increase the distance between the pipeline 10 and the external pressure component, avoid direct contact between the pressure component and the pipeline 10, and play a protective effect. In this way, the device can be prevented from being directly flattened under the action of external pressure, resulting in the pressure component being close to the pipeline 10. It is also beneficial to reduce the degree of damage to the device under external pressure, and it can be recycled and reused.

[0036] Example 3 like Figure 8 As shown, a device for preventing a gas pipeline from being damaged by a third party in this embodiment is, on the basis of Embodiment 1, the radial strip 4 is provided with a joint portion 8, the joint portion 8 comprises a first hinged portion 81 and a second hinged portion 82 which are hingedly connected, and the first hinged portion 81 and the second hinged portion 82 are connected to an elastic mechanism 83.

[0037] In the present embodiment, a device for preventing a gas transmission pipeline from being damaged by a third party is provided, and further structural limitations are imposed on the radial strip 4. A joint portion 8 is provided on the radial strip 4, and the joint portion 8 is hinged with the first hinge portion 81 and the second hinge portion 82 to realize the hinged connection of the two parts of the radial strip 4. When the device is subjected to external pressure, the radial strip 4 can bend at the joint portion 8, and an elastic mechanism 83, such as a spring, provides a bending buffering force to the joint portion 8, so that the radial strip 4 can have a buffering effect under the action of external pressure, thereby preventing the external pressure from being directly transmitted to the pipeline 10. After the external pressure disappears, the radial strip 4 can also have a certain reset ability under the action of the elastic mechanism 83, so that the device has a certain anti-deformation ability, thereby achieving a good protective effect on the pipeline 10.

[0038] Example 4 like Fig. 9As shown, a device for preventing a gas pipeline from being damaged by a third party in this embodiment is, on the basis of embodiment 1, an outer ring component 3 is embedded with a warning mechanism 9, the warning mechanism 9 includes a light strip, the warning mechanism 9 is connected to a control mechanism, and a reflective strip is provided on the axial strip 5 connected to the inner ring component 2.

[0039] A device for preventing a gas pipeline from being damaged by a third party in this embodiment comprises a light strip as a warning mechanism 9 provided on an outer ring component 3. After the outer ring component 3 is assembled, the light strip is embedded in a groove formed on the outer ring or inner ring of the outer ring component 3 to form an outer ring component 3 with a lighting effect. The light strip is connected to a control mechanism, and the control mechanism controls the lighting and extinguishing of the light strip. In actual settings, electronic devices are used to achieve remote control or on-site manual control, so as to further enhance the warning effect of the device by lighting the light strip, so that third-party construction personnel can more easily notice the position of the pipeline 10 and avoid damage to the pipeline 10 caused by misoperation.

[0040] Preferably, the light strip can be set with variable lighting according to actual conditions, and the light of the light strip is projected onto the reflective strip of the axial strip 5 of the inner ring component 2, which can improve the identification effect of the pipeline 10 and further improve the warning effect of the device.
