Description

Technical Field

[0001] This utility model relates to the field of protective devices, and in particular to a protective device for natural gas transportation pipelines. Background Technology

[0002] Natural gas pipelines, also known as gas transmission pipelines, are pipeline facilities used to transport purified natural gas from mines between different regions. They are often referred to as "long-distance pipelines" and constitute the main transportation channels for natural gas from production sites to storage facilities and then to users. These pipeline systems include lines, stations, and auxiliary facilities, and possess key properties such as corrosion resistance, sealing, pressure resistance, and safety to ensure that natural gas can be safely and efficiently delivered to users.

[0003] In current technology, most natural gas pipelines are directly buried underground. However, underground conditions are complex, and corrosion can cause damage to natural gas pipelines. In addition, various external forces on the surface can also cause damage to natural gas pipelines. Although there are devices on the market to protect natural gas transportation pipelines, these devices often involve adding various annular protective layers or wrapping protective layers to the outside of the natural gas transportation pipeline. Their protective structure is relatively simple, which means that they cannot provide effective protection for natural gas pipelines. At the same time, most protective devices are installed on the outside of the natural gas transportation pipeline by bolts, which is cumbersome to install. This not only reduces the protective effect and construction efficiency of natural gas transportation pipelines, but also shortens the service life of natural gas transportation pipelines. Utility Model Content

[0004] The main objective of this invention is to provide a protective device for natural gas transport pipelines, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A protective device for a natural gas transport pipeline includes a natural gas transport pipeline body. Several protective mechanisms are fitted around the outside of the natural gas transport pipeline body, and these mechanisms are fixedly connected end-to-end. Each protective mechanism includes an outer protective sleeve, a rubber sleeve, transverse ribs, annular ribs, a connecting ring, a threaded short rod, and a limiting pin. The rubber sleeve is fixedly connected inside the outer protective sleeve, and several transverse ribs are fixedly connected to the inner wall of the rubber sleeve inside the outer protective sleeve. Several annular ribs are also fixedly connected between the transverse ribs. The connecting ring is fixedly connected to one end of the outer wall of the outer protective sleeve, and the threaded short rod is movably connected to symmetrical lugs on the outer wall of the connecting ring. The limiting pin is fixedly connected to the inner end of the threaded short rod.

[0007] Preferably, the outer protective sleeve has a concave cavity inside, and a rubber sleeve is fixedly installed inside the concave cavity.

[0008] Preferably, the interior of the concave cavity is fixedly installed with a number of transverse ribs in a ring array, and the interior of the concave cavity is also fixedly installed with a number of ring ribs intersecting with the transverse ribs in a transverse array, the transverse ribs and the ring ribs together forming a mesh rib cage structure.

[0009] Preferably, a fixing ring is fixedly installed on the right end of the outer wall of the outer protective sleeve, and a set of symmetrical positioning holes are opened on the side wall of the fixing ring, and a set of symmetrical limiting holes are opened on the outer ring wall of the fixing ring.

[0010] Preferably, a connecting ring is fixedly installed on the left end of the outer wall of the outer protective sleeve, and a set of symmetrical positioning rods are fixedly installed on the outer wall of the connecting ring. On the outer wall of the connecting ring and between the positioning rods, there are also mutually symmetrical ear blocks fixedly installed, and threaded holes are opened on the side wall of the ear blocks.

[0011] Preferably, the threaded short rod is threadedly connected to the threaded hole, and a knob is fixedly installed on the outer end of the threaded short rod, while a limit pin is fixedly installed on the inner end of the threaded short rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, several protective mechanisms are fitted onto the outside of the natural gas transport pipe body. The positioning rod on the rear connecting ring is inserted into the positioning hole on the front fixing ring. Rotating the knob pushes the limiting pin into the limiting hole via a threaded short rod. This allows for the rapid connection and installation of the protective mechanisms on the outside of the natural gas transport pipe body, improving construction efficiency. The outer protective sleeve isolates the pipe from external media, providing external protection. The rubber sleeve installed in the concave cavity of the outer protective sleeve, based on its material and structural characteristics, provides elastic cushioning against impacts or pressures on the natural gas transport pipe body. Furthermore, the transverse and annular ribs form a mesh cage structure, effectively reducing deformation of the natural gas transport pipe body, significantly improving its load-bearing capacity, enabling it to withstand greater pressure, enhancing its compressive strength, maintaining its overall shape and stability, and extending its service life. This provides effective protection for the natural gas transport pipe body. Attached Figure Description

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1 - Figure 4 As shown, a natural gas transport pipeline protection device includes a natural gas transport pipeline body 1. Several protective mechanisms 2 are sleeved on the outside of the natural gas transport pipeline body 1, and the several protective mechanisms 2 are fixedly connected to each other in a head-to-tail manner. The protective mechanism 2 includes an outer protective sleeve 3, a rubber sleeve 5, transverse ribs 6, annular ribs 7, a connecting ring 11, a threaded short rod 15, and a limiting pin 17. The rubber sleeve 5 is fixedly connected inside the outer protective sleeve 3, and several transverse ribs 6 are fixedly connected inside the outer protective sleeve 3 and on the inner wall of the rubber sleeve 5. Several annular ribs 7 are also fixedly connected between the several transverse ribs 6. The connecting ring 11 is fixedly connected to one end of the outer wall of the outer protective sleeve 3, and the threaded short rod 15 is movably connected to the symmetrical lugs 13 on the outer side wall of the connecting ring 11. The limiting pin 17 is fixedly connected to the inner end of the threaded short rod 15.

[0021] like Figure 2 As shown, the outer protective sleeve 3 has a concave cavity 4 inside. The outer protective sleeve 3 can provide external protection for the natural gas transport pipe body 1, preventing the natural gas transport pipe body 1 from being in contact with the external medium for a long time, which may lead to corrosion and damage. In addition, a rubber sleeve 5 is fixedly installed inside the concave cavity 4. The rubber sleeve 5 installed inside the concave cavity 4 can play an elastic buffering role when the natural gas transport pipe body 1 is impacted, based on its own material structure characteristics, preventing the natural gas transport pipe body 1 from cracking and being damaged due to excessive impact force.

[0022] like Figure 2As shown, several transverse ribs 6 are fixedly installed in a ring array inside the concave cavity 4, and several ring ribs 7 intersecting with the transverse ribs 6 are also fixedly installed in a transverse array inside the concave cavity 4. The transverse ribs 6 and the ring ribs 7 together form a mesh cage structure, which can effectively reduce the deformation of the natural gas transportation pipe body 1, significantly improve the load-bearing capacity of the natural gas transportation pipe body 1, enable it to withstand greater pressure, maintain its overall shape and stability, and extend the service life of the pipeline.

[0023] like Figure 3 As shown, a fixing ring 8 is fixedly installed on the right end of the outer wall of the outer protective sleeve 3, and a set of symmetrical positioning holes 9 are opened on the side wall of the fixing ring 8. The positioning holes 9 are used to cooperate with the positioning rod 12 to position and splice the outer protective sleeve 3 behind. A set of symmetrical limiting holes 10 are opened on the outer ring wall of the fixing ring 8. The limiting holes 10 are used to cooperate with the limiting pin rod 17 to limit the connection of the outer protective sleeve 3.

[0024] like Figure 4 As shown, a connecting ring 11 is fixedly installed on the left end of the outer wall of the outer protective sleeve 3, and a set of symmetrical positioning rods 12 are fixedly installed on the outer side wall of the connecting ring 11. The positioning rods 12 installed on the connecting ring 11 at the left end of the outer wall of the rear outer protective sleeve 3 are inserted into the positioning holes 9 opened on the fixing ring 8 at the right end of the outer wall of the front outer protective sleeve 3, so that the two adjacent outer protective sleeves 3 can be positioned and connected together. On the outer side wall of the connecting ring 11 and between the positioning rods 12, there are also mutually symmetrical ear blocks 13 fixedly installed, and threaded holes 14 are opened on the side wall of the ear blocks 13. The threaded holes 14 opened on the side wall of the ear blocks 13 are used to cooperate with the threaded short rod 15 to realize the threaded rotation and movement operation.

[0025] like Figure 4 As shown, the threaded short rod 15 is threadedly connected to the threaded hole 14, and a knob 16 is fixedly installed on the outer end of the threaded short rod 15. A limit pin 17 is fixedly installed on the inner end of the threaded short rod 15. By rotating the threaded short rod 15 in the threaded hole 14 through the knob 16, the threaded short rod 15 can be rotated and push the limit pin 17 to move inward. After the limit pin 17 is inserted into the limit hole 10, the outer protective sleeves 3 can be connected and fixed to the outside of the natural gas transportation pipe body 1 to cooperate with the natural gas transportation pipe body 1 to provide effective protection.

[0026] The specific working principle of the protective mechanism 2 in conjunction with the natural gas transportation pipe body 1 is as follows:

[0027] According to the length of the natural gas transport pipe body 1, several outer protective sleeves 3 are sequentially fitted onto the outside of the natural gas transport pipe body 1. During fitting, the positioning rod 12 on the outer wall of the connecting ring 11 installed at the left end of the outer wall of the rear outer protective sleeve 3 is inserted into the positioning hole 9 opened on the outer wall of the fixing ring 8 installed at the right end of the outer wall of the front outer protective sleeve 3. Then, the knob 16 located outside the lug 13 installed on the outer wall of the connecting ring 11 is rotated. The knob 16 will drive the threaded short rod 15 to achieve threaded rotation operation in the threaded hole 14 opened on the side wall of the lug 13. After continuously rotating the knob 16, the threaded short rod 15 will push the inner end of the limiting pin 17 inward until the limiting pin 17 is inserted into the limiting hole 10 on the outer wall of the front fixing ring 8, making the knob 16 unable to rotate. Then, the two adjacent outer protective sleeves 3 fitted onto the outer wall of the natural gas transport pipe body 1 can be quickly connected and fixed together end to end. This facilitates the installation of the protective mechanism 2 and improves construction efficiency. During the use of the natural gas transport pipe body 1... The outer protective sleeve 3 provides external protection for the natural gas pipeline body 1, preventing corrosion and damage caused by prolonged contact with external media while buried underground. Combined with the rubber sleeve 5 installed in the concave cavity 4 within the outer protective sleeve 3, the rubber sleeve 5 provides elastic cushioning to the natural gas pipeline body 1 when subjected to external collisions or impacts, preventing breakage due to excessive impact force. Furthermore, the mesh-like cage structure formed by the transverse ribs 6 and annular ribs 7, when fitted around the natural gas pipeline body 1, effectively reduces deformation under pressure, significantly improving its load-bearing capacity, enabling it to withstand greater pressure, enhancing its compressive strength, maintaining its overall shape and stability, and extending its service life. Therefore, it effectively protects the natural gas pipeline body 1.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, various improvements can be made to it without departing from the scope of the present utility model, and components can be replaced with equivalents or some technical features can be replaced with equivalents. All such improvements within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
