Description

Technical Field

[0001] The utility model relates to the technical field of gas pipelines, in particular to a gas pipeline safety protection structure. Background Art

[0002] Gas pipelines transport flammable and explosive natural gas. Due to the unknown location of the pipelines or non-standard construction, a considerable number of gas accidents are caused by third-party construction that damages or cuts the gas pipelines. Moreover, most gas pipelines are directly buried in the underground soil layer. There are no protective measures, and the pipelines are easily subjected to gravity pressure, causing pipeline damage. The application document with application number CN202211638904.8 discloses an anti-excavation protective structure for long-distance pipelines, including geogrids. The geogrids are buried below the ground and located above the oil and gas pipelines, which can effectively prevent damage to the oil and gas pipelines caused by third-party excavation. However, this protective structure simply lays the geogrid in the soil layer above the pipeline, lacks measures to fix the geogrid, and the geogrid is prone to dislocation during the entire laying process. Moreover, this protective structure only protects the top of the pipeline, and there is a lack of effective protective measures on both sides of the pipeline, resulting in poor overall protection effect. Utility Model Content

[0003] In order to solve the technical problems in the above-mentioned background technology that gas pipelines are easily affected by gravity pressure and construction damage, and that the existing technology has poor protection effect on pipelines and the protective net is prone to displacement, the utility model provides a gas pipeline safety protection structure.

[0004] The technical solution of this utility model is as follows:

[0005] A gas pipeline safety protection structure includes several gantry frame-shaped support mechanisms arranged in front and behind, and a protective net covered on the outside of the gantry frame-shaped support mechanisms; the support mechanism includes an "N"-shaped support rod, and both sides of the support rod are provided with a limit rod with one end connected to the support rod and the other end passing through the mesh of the protective net; it also includes a fixing part movably arranged on the upper side of the support rod, and the fixing part is arranged to pass through the mesh of the protective net and connect to the support rod, and press the protective net and the support rod to fix them.

[0006] The protective net is supported by the N-shaped support rod and is installed above the gas pipeline. It can protect the gas pipeline from above and on both sides, achieving a multi-directional protection effect. At the same time, the protective net is fixed by the limit rods and fixings on the support rods to prevent the protective net from displacement during the subsequent construction process, thereby ensuring the protective effect of the protective net.

[0007] Specifically, the fixing member comprises an arched buckle, and a snap-on clip is provided on the upper side of the support rod. The two ends of the arched buckle are respectively passed through two different meshes of the protective net and snap-connected with the snap-on clip. After the two ends of the arched buckle are passed through the meshes of the protective net, they are immediately snapped into the snap-on clip. The portion of the protective net between the two meshes is pressed and fixed above the support rod by the arched buckle, thereby restricting the movement of the protective net.

[0008] Furthermore, a spring is provided between the two sides of the arch buckle, which squeezes the two sides of the arch buckle to reduce the distance between the two ends, thereby ensuring that the arch buckle can be snapped into the bayonet. After the two ends of the arch buckle are snapped into place, under the action of the spring, the distance between the two ends of the arch buckle returns to its original state, thereby ensuring that the arch buckle will not detach from the bayonet.

[0009] Specifically, the support rods comprise two opposing bent rods, each comprising a vertical section and a first horizontal section at its upper end. A horizontal rod is connected between the first horizontal sections of the two bent rods, and the spacing between the two bent rods is adjustable. By adjusting the spacing between the two bent rods, the coverage area of ​​the support rods can be varied, making it suitable for a variety of protective working conditions.

[0010] As a preferred embodiment, the connection between the vertical section and the first horizontal section is an arc-shaped transition. The arc-shaped setting can reduce the friction of the support rod on the protective net, and the protective net can better fit the support rod.

[0011] Further preferably, one end of the limit rod is connected to the support rod, and the other end is inclined toward the outer side and downward of the support rod. The inclined limit rod enables the protective net to play a certain limiting role when it is subjected to tension in different directions, preventing the protective net from falling off the limit rod.

[0012] As a preferred embodiment, the limit rod is bent toward the support rod at one end away from the support rod, thereby further enhancing the limiting effect of the limit rod. When the protective net moves, the bent end of the limit rod can hook the mesh of the protective net again to prevent the protective net from further movement.

[0013] Preferably, the surface of the protective net is coated with an orange-yellow resin adhesive layer. The orange color has a striking effect and can serve as a warning when a third-party construction worker accidentally digs into the protective net layer. In addition, the resin adhesive is waterproof, oil-resistant, and resistant to strong acids and alkalis, which can enhance the protective effect and durability of the protective net.

[0014] Through the above design, the beneficial effects of the gas pipeline safety protection structure of the utility model are:

[0015] (1) The coordination between the protective net and the supporting structure provides better protection above and on both sides of the gas pipeline. The protective net has good protection effect and wide coverage.

[0016] (2) The setting of the upper limit rod and the fixing parts on the support rod can fix the guardrail to prevent the guardrail from being displaced during the construction process.

[0017] (3) The coverage of the support rod is adjustable and can be matched with protective nets of different sizes to adapt to various protection conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Example

[0026] Combine Figure 1 and Figure 2 This embodiment provides a gas pipeline safety protection structure comprising a plurality of gantry-frame support mechanisms 1 arranged in a front-to-rear manner, and a protective net 2 disposed on the outer surface thereof. The protective net 2, supported by the support mechanisms 1, is positioned above the gas pipeline, providing protection above and on both sides of the gas pipeline, achieving a comprehensive protection effect. The following describes the structure of the protective structure (a gas pipeline safety protection structure described above) in detail.

[0027] Specifically speaking, the structure of the guard net 2 is combined with Figure 3 The protective net 2 includes a plurality of webbings 21, which are arranged in a grid-like manner in a staggered manner in the warp and weft directions, and the plurality of webbings 21 are arranged in an equidistant array along the warp and weft directions to ensure that the strength of the protective net 2 in the warp and weft directions is consistent.

[0028] Exemplarily, the protective net 2 is made of industrial high-strength, high-modulus, low-shrinkage polyester fiber material, which has the properties of corrosion resistance, aging resistance and long service life.

[0029] Preferably, the surface of the protective net 2 is coated with an orange-yellow resin adhesive layer. The orange color has a striking effect and can serve as a warning when a third-party construction worker accidentally digs into the protective net 2 layer. Moreover, the resin adhesive is waterproof, oil-resistant, and resistant to strong acids and alkalis, which can enhance the protective effect and durability of the protective net 2.

[0030] In this embodiment, combined with Figure 1 The support mechanism 1 includes an "n"-shaped support rod 11, and a limiting rod 12 is provided on both sides of the support rod 11 at one end and passes through the mesh of the protective net 2 at the other end.

[0031] Further preferably, one end of the limit rod 12 is connected to the support rod 11, and the other end is inclined toward the outer side and downward of the support rod 11. The inclined limit rod 12 enables the protective net 2 to play a certain limiting role when it is subjected to tension in different directions, preventing the protective net 2 from falling off from the limit rod 12.

[0032] As a preferred embodiment, the limiting rod 12 is bent toward the support rod 11 at one end away from the support rod 11, thereby further enhancing the limiting effect of the limiting rod 12. When the protective net 2 moves, the bent end of the limiting rod 12 can hook the mesh of the protective net 2 again to prevent the protective net 2 from further movement.

[0033] Exemplarily, both ends of the support rod 11 are provided with a fixing seat 13, and the fixing seat 13 can increase the contact area between the support rod 11 and the soil layer, improve the friction between the support rod 11 and the soil layer, and at the same time can support the support rod 11 and keep the support rod 11 upright before sudden backfilling.

[0034] Specifically, the support rod 11 comprises two opposing bent rods 111, each comprising a vertical section and a first horizontal section at its upper end. A horizontal rod 112 is connected between the first horizontal sections of the two bent rods 111, and the spacing between the two bent rods 111 is adjustable. By adjusting the spacing between the two bent rods 111, the coverage area of ​​the support rod 11 can be varied, making it suitable for various protective working conditions.

[0035] As a preferred embodiment, the connection between the vertical section and the first horizontal section is an arc-shaped transition. The arc-shaped setting can reduce the friction of the support rod 11 on the protective net 2, and the protective net 2 can better fit the support rod 11.

[0036] In a specific embodiment, the opposing ends of the two first horizontal sections are provided with openings, and the ends of the horizontal rod 112 are configured to be respectively snapped into the two openings. Fastening bolts are provided on the opposing side walls of the two first horizontal sections. After adjusting the spacing between the two bent rods 111 and installing the horizontal rods 112, tightening the fastening bolts securely connects the horizontal rods 112 to the bent rods 111.

[0037] In this embodiment, the protective structure further includes a fixing member 3 movably arranged on the upper side of the support rod 11 , and the fixing member 3 is configured to pass through the mesh of the protective net 2 and connect to the support rod 11 , and press the protective net 2 and the support rod 11 to fix them.

[0038] Specifically, the fixing member 3 comprises an arched buckle, and a bayonet is provided on the upper side of the support rod 11. The ends of the arched buckle are respectively passed through two different meshes of the protective net 2 and are then engaged with the bayonet. After the ends of the arched buckle are passed through the meshes of the protective net 2, they are immediately engaged in the bayonet. The portion of the protective net 2 between the two meshes is pressed and fixed above the support rod 11 by the arched buckle, thereby restricting the movement of the protective net 2.

[0039] In specific implementation, combined with Figure 4 The arched buckle 31 includes an arched segment and second horizontal segments at either end, with the two second horizontal segments extending away from the arched segment. The bayonet is disposed along the length of the horizontal rod 112, and blind holes are provided on two opposing walls of the bayonet along the length of the horizontal rod 112. The two second horizontal segments are configured to engage with the blind holes.

[0040] Furthermore, a spring 32 is provided between the two sides of the arch buckle, which squeezes the two sides of the arch buckle to reduce the distance between the two ends, ensuring that the arch buckle can be snapped into the bayonet. After the two ends of the arch buckle are snapped into place, under the action of the spring 32, the distance between the two ends of the arch buckle returns to its original state, ensuring that the arch buckle will not detach from the bayonet.

[0041] After the gas pipeline is installed, several support rods 11 are first placed above the pipeline along the length of the pipeline, and then part of the soil is backfilled until the soil layer above the pipeline is close to the inside of the support rods 11. Then the protective net 2 is placed above the support rods 11 and fixed to the protective net 2 by the limit rods 12 and the fixing parts 3, and finally the soil is backfilled.

[0042] The utility model provides a gas pipeline safety protection structure with good protection above and on both sides of the gas pipeline through the cooperation of the protective net 2 and the support mechanism 1. The protective net 2 has a good protection effect and a wide coverage range. Moreover, the setting of the upper limit rod 12 and the fixing member 3 on the support rod 11 can fix the protective net 2 to prevent the protective net 2 from being displaced during the construction process. At the same time, the coverage range of the support rod 11 is adjustable and cooperates with the protective nets 2 of different sizes to adapt to a variety of protection working conditions. The utility model can protect the gas pipeline, prevent the pipeline from being damaged by gravity pressure, and be severely hit by sharp objects, thereby damaging the gas pipeline. Moreover, it covers the upper soil layer of the gas pipeline and serves as a warning.
