It should also be understood that terms such as those defined in a general dictionary should be understood to have a meaning consistent with the meaning in the context of the prior art, and will not be interpreted with an idealized or overly formal meaning unless specifically defined as here.

[0049] The present application provides a pressure-sensitive protection sleeve for gas pipelines, as Figure 1As shown, the pressure-sensitive protection sleeve for a gas pipeline includes a first arc-shaped sleeve 100, a second arc-shaped sleeve 101, at least two buckles 102, a pressure-sensitive detection component, a telescopic rigid tube 1 (such as Figure 6 and Figure 7 shown), a bracket 3 (such as Figure 6 and Figure 7 shown), and a positioning mechanism 4 (such as Figure 7 shown); the second arc-shaped sleeve 101 is used to enclose with the first arc-shaped sleeve 100 to form a circular accommodation space; mounting holes 103 are provided on both the first arc-shaped sleeve 100 and the second arc-shaped sleeve 101; the accommodation space is used to house the gas pipeline; at least two buckles 102 are used to buckle the two sides of the first arc-shaped sleeve 100 with the second arc-shaped sleeve 101 respectively; the pressure-sensitive detection component is arranged inside the first arc-shaped sleeve 100 and the second arc-shaped sleeve 101; the telescopic rigid tube 1 is detachably arranged in the mounting hole 103; the bracket 3 is sleeved on the telescopic rigid tube 1 and can slide along the telescopic rigid tube 1 to expand and fold; the positioning mechanism 4 is movably connected to the bracket 3 and cooperates with the telescopic rigid tube 1 to position the bracket 3 in the expanded state and the folded state.

[0050] Specifically, the first arc-shaped sleeve 100 and the second arc-shaped sleeve 101 can be of a symmetric structure (i.e., the arcs of the two arc-shaped sleeves are equal) or an asymmetric structure (i.e., the arcs of the two arc-shaped sleeves are not equal); the first arc-shaped sleeve 100 and the second arc-shaped sleeve 101 cooperate with each other and are spliced and sleeved around the periphery of the gas pipeline, so that the two arc-shaped sleeves can enclose to form the circular accommodation space.

[0051] After the first arc-shaped sleeve 100 and the second arc-shaped sleeve 101 are spliced around the periphery of the gas pipeline, they are assembled through the buckles 102 to ensure that the first arc-shaped sleeve 100 and the second arc-shaped sleeve 101 can be firmly fixed outside the gas pipeline and will not separate from the gas pipeline. At least one buckle 102 is distributed on each side of the first arc-shaped sleeve 100 to ensure the smooth assembly of the first arc-shaped sleeve 100 and the second arc-shaped sleeve 101. The buckle 102 can adopt the existing technology, and the structure of the buckle 102 will not be described in detail here.

[0052] The pressure-sensitive detection component is used to detect pressure changes within the first arc-shaped sleeve 100 and the second arc-shaped sleeve 101, so as to determine whether the gas pipeline is deformed according to the pressure detection results. Once the inner gas pipeline is deformed, the pressure detected by the pressure-sensitive detection component will change abnormally (such as a pressure increase), monitoring the pressure states of various parts of the protected gas pipeline and timely grasping the dynamic deformation of the gas pipeline; the pressure-sensitive detection component is connected to an external control system, so as to transmit the detected pressure change to the external control system through a signal, and the external control system triggers an alarm system to remind the staff that the gas pipeline is deformed. Under the protection of the external barriers of the first arc-shaped sleeve 100 and the second arc-shaped sleeve 101, even if gas leaks due to the deformation of the gas pipeline, the leaked gas will not immediately disperse to the outside world.

[0053] The telescopic rigid pipe 1 cooperates with the bracket 3 and is used to support the first arc-shaped sleeve 100 and the second arc-shaped sleeve 101, preventing the suspended first arc-shaped sleeve 100 and second arc-shaped sleeve 101 from being unevenly stressed or falling off under the action of gravity. The telescopic rigid pipe 1 has telescopic characteristics and is made of hard materials such as stainless steel; the bracket 3 is sleeved on the telescopic rigid pipe 1 and can slide along the telescopic rigid pipe 1 to expand and close, so as to realize the adjustment of the state of the bracket 3. The positioning mechanism 4 is movably connected to the bracket 3 and cooperates with the telescopic rigid pipe 1 to position the bracket 3, so as to position the bracket 3 in the expanded state and the closed state. Since the telescopic rigid pipe 1 has telescopic performance, by adjusting the telescopic rigid pipe 1, the overall height of the telescopic rigid pipe 1 can be adjusted when the bracket 3 is in the expanded state, so as to adjust the support height for the first arc-shaped sleeve 100 and the second arc-shaped sleeve 101 to adapt to the heights of gas pipelines in different sections.

[0054] It can be seen that in this application, the first arc-shaped sleeve 100 and the second arc-shaped sleeve 101 are designed into a cover-type structure, which is convenient for installing or disassembling around the gas pipeline at any time; by detecting the pressure with the pressure-sensitive detection component to judge whether there is gas leakage, and also supporting the first arc-shaped sleeve 100 and the second arc-shaped sleeve 101 with the telescopic rigid pipe 1 and the bracket 3 and adjusting the support height to adapt to the heights of gas pipelines in different sections, so that the first arc-shaped sleeve 100 and the second arc-shaped sleeve 101 can be positioned around the gas pipeline, while protecting the gas pipeline, preventing the gas pipeline from being damaged by third-party construction, reducing the deformation of the gas pipeline, detecting whether the gas pipeline is deformed; and can protect the gas pipeline when gas leaks, avoiding the leaked gas from directly spreading to the outside world, and further improving the gas use safety.

[0055] In an embodiment of the present application, the pressure-sensitive detection component includes a plurality of pressure-sensitive detection units, which are sequentially distributed along the axial direction of the accommodation space; the pressure-sensitive detection unit includes a plurality of pressure sensors 109 (as Figure 2 shown), and the plurality of pressure sensors 109 are evenly arranged along the circumferential direction of the accommodation space;

[0056] Specifically, if a leak occurs on one side, relying only on a single or unevenly distributed sensor may result in a detection blind spot and delay the alarm time; therefore, in this embodiment, arranging the plurality of pressure sensors 109 evenly along the circumferential direction of the accommodation space can ensure that as many pressure changes along the circumference of the gas pipeline as possible can be captured in a timely manner, quickly locate the specific pipeline deformation position, and reduce misjudgment; moreover, the plurality of pressure sensors 109 provide redundant monitoring capabilities, and even if a certain pressure sensor fails, other pressure sensors can still work normally, improving the reliability of the overall application.

[0057] In an embodiment of this embodiment, the pressure sensor 109 is arranged to extend radially along the accommodation space.

[0058] Specifically, the pressure sensor 109 is arranged to extend radially along the accommodation space, which can penetrate into different depths in the radial direction of the pressure-sensitive protection sleeve for the gas pipeline, can more sensitively sense the small pressure gradient changes along the radial direction, and more comprehensively monitor the pressure fluctuations at different levels, avoiding false alarms or missed alarms. The superposition of the radial extension of the pressure sensor 109 and the circumferential distribution along the accommodation space enables the detection of pressure changes in multiple directions and depths, thereby providing a more accurate basis for judging whether the gas pipeline is deformed.

[0059] In an embodiment of the present application, as Figure 1 shown, the pressure-sensitive protection sleeve for the gas pipeline further includes an anti-static buffer layer 108, and the anti-static buffer layer 108 is arranged on the inner side walls of the first arc-shaped sleeve 100 and the second arc-shaped sleeve 101.

[0060] Specifically, the anti-static buffer layer 108 is made of anti-static buffer material, which plays a buffering role for the gas pipeline, reduces the generation of static electricity at the same time, and reduces the occurrence of gas leakage accidents.

[0061] As Figure 3As shown, the pressure-sensitive protection sleeve for a gas pipeline further includes a plurality of receiving grooves 104 and a plurality of insertion portions 105; the plurality of receiving grooves 104 are respectively disposed on the first arc-shaped sleeve 100 and the second arc-shaped sleeve 101; the receiving groove 104 has an opening; the plurality of insertion portions 105 are respectively disposed on the first arc-shaped sleeve 100 and the second arc-shaped sleeve 101; the receiving grooves 104 and the insertion portions 105 correspond to each other one by one and cooperate with each other.

[0062] Specifically, the receiving groove 104 and the insertion portion 105 are respectively disposed at the butt joint of the first arc-shaped sleeve 100 and the second arc-shaped sleeve 101. Similarly, the receiving groove 104 and the insertion portion 105 are also respectively disposed at the butt joint of the second arc-shaped sleeve 101 and the first arc-shaped sleeve 100; the insertion portion 105 and the receiving groove 104 are in a detachable plug-in fit, so as to increase the assembly contact area between the first arc-shaped sleeve 100 and the second arc-shaped sleeve 101, and achieve the purpose of improving the assembly stability between the first arc-shaped sleeve 100 and the second arc-shaped sleeve 101.

[0063] As Figure 3 , Figure 4 and Figure 5 shown, the pressure-sensitive protection sleeve for a gas pipeline further includes a plurality of elastic stoppers 106 and a limit ring 107; the plurality of elastic stoppers 106 are disposed on the inner wall of the receiving groove 104 and are arranged in sequence along the circumferential direction; the limit ring 107 is sleeved on the outer side of the insertion portion 105; when the insertion portion 105 and the receiving groove 104 are in a plugged state, the limit ring 107 is located on the side of the elastic stopper 106 away from the opening.

[0064] Specifically, the elastic stopper 106 is elastic so that the stop ring 107 can be inserted into or pulled out of the receiving groove 104. When the first arc sleeve 100 and the second arc sleeve 101 are assembled, the plug-in portion 105 is aligned with the receiving groove 104 one by one, and the first arc sleeve 100 and the second arc sleeve 101 are pushed closer to each other, so that the plug-in portion 105 is gradually inserted into the receiving groove 104; as the plug-in portion 105 is pushed forward, the stop ring 107 contacts and squeezes the elastic stopper 106, so that the elastic stopper 106 is deformed and makes way for the stop ring 107 and the plug-in portion 105. When the plug-in portion 105 is assembled with the receiving groove 104, the limiting ring 107 moves to the side of the elastic stopper 106 away from the opening, and the elastic stopper 106 restores its elastic deformation and limits the limiting ring 107; then the first arc sleeve 100 and the second arc sleeve 101 are locked with the buckle 102, so that the first arc sleeve 100 and the second arc sleeve 101 can be enclosed around the periphery of the gas pipeline.

[0065] like Figure 6 As shown, the bracket 3 includes a positioning ring 31, three supporting legs 32 and a supporting rod 33; the positioning ring 31 is sleeved on the telescopic rigid tube 1, and can slide back and forth along the telescopic rigid tube 1 (i.e., the axial direction of the telescopic rigid tube 1); the three supporting legs 32 are evenly distributed in sequence along the circumferential direction of the positioning ring 31; one end of the supporting leg 32 is rotatably connected to the positioning ring 31, and the other end is used to support the ground; the two ends of the supporting rod 33 are respectively hinged to the supporting leg 32 and the telescopic rigid tube 1.

[0066] like Figure 7As shown, when the bracket 3 is in the closed state, the support leg 32 is parallel to the telescopic rigid tube 1. When the bracket 3 is in the closed state, the telescopic rigid tube 1 extends beyond the support leg 32, or the end of the support leg 32 away from the positioning ring 31 is flush with the telescopic rigid tube 1. When it is necessary to support the first arc-shaped sleeve 100 and the second arc-shaped sleeve 101, adjust the positioning mechanism 4 to make the positioning ring 31 slidable; place the telescopic rigid tube 1 in a vertical state and slide the positioning ring 31 downward along the telescopic rigid tube 1, then the support leg 32 rotates relative to the positioning ring 31, and the end of the support leg 32 not connected to the positioning ring 31 moves outward, and the ends of the three support legs 32 not connected to the positioning ring 31 are separated from each other, and the support rod 33 rotates relative to both the support leg 32 and the telescopic rigid tube 1. When the positioning ring 31 moves to a position where the support leg 32 extends beyond the telescopic rigid tube 1, the positioning mechanism 4 can be adjusted to position the bracket 3 at the current height; it can be understood that after the positioning ring 31 moves to a position where the support leg 32 extends beyond the telescopic rigid tube 1, the positioning ring 31 can continue to move downward, thereby increasing the overall height of the first arc-shaped sleeve 100 and the second arc-shaped sleeve 101.

[0067] It should be noted that when the support leg 32 rotates relative to the positioning ring 31 until the angle between the support leg 32 and the telescopic rigid tube 1 reaches the maximum, the bracket 3 reaches the deployed state, the support leg 32 is inclined, and the end of the support leg 32 away from the positioning ring 31 can support the ground.

[0068] To improve the stability of the support of the bracket 3 for the telescopic rigid tube 1, when the bracket 3 is in the open state, as Figure 6 shown, the support rod 33 forms a triangular structure with the telescopic rigid tube 1 and the support leg 32, and the support rod 33 also forms a triangular structure with the support leg 32 and the ground.

[0069] The positioning mechanism 4 includes an adjusting rod and a limiting stop; one end of the adjusting rod is inserted into the positioning ring 31 and is threadedly connected to the positioning ring 31; the adjusting rod is arranged radially along the telescopic rigid tube 1. Therefore, by rotating the adjusting rod, the relative position between the adjusting rod and the telescopic rigid tube 1 can be adjusted, so that the adjusting rod abuts against and moves away from the telescopic rigid tube 1; the other end of the adjusting rod is located outside the positioning ring 31. The limiting stop is connected to the end of the adjusting rod located outside the positioning ring 31.

[0070] The limiting stop is used to limit the adjusting rod, so that at least a part of the adjusting rod can be located outside the positioning ring 31, facilitating the staff to adjust the adjusting rod. The limiting stop is also used for the staff to hold, so as to rotate the adjusting rod. When the adjusting rod moves into the positioning ring 31 and presses against the telescopic rigid tube 1, the position of the positioning ring 31 is positioned, and the bracket 3 is positioned. When the adjusting rod moves out of the positioning ring 31 and gradually loosens relative to the telescopic rigid tube 1, the positioning ring 31 can slide relative to the telescopic rigid tube 1, thereby adjusting the height of the bracket 3.

[0071] As Figure 6 shown, the telescopic rigid tube 1 includes a mother tube 11, a first support tube 13, a first positioning assembly 12, a second support tube 14 and a second positioning assembly 15; the bracket 3 is arranged on the mother tube 11; one end of the first support tube 13 is inserted into the mother tube 11, and the other end is located outside the mother tube 11; the first support tube 13 can reciprocate relative to the mother tube 11; the first positioning assembly 12 is movably connected to the mother tube 11 and cooperates with the first support tube 13 to position the first support tube 13; one end of the second support tube 14 is inserted into the first support tube 13, and the other end is located outside the second support tube 14; the second support tube 14 can reciprocate relative to the first support tube 13; the second positioning assembly 15 is movably connected to the first support tube 13 and cooperates with the second support tube 14 to position the second support tube 14.

[0072] The first positioning assembly 12 is used to limit the overlapping height between the first support tube 13 and the mother tube 11, thereby positioning the height of the first support tube 13; the second positioning assembly 15 is used to limit the overlapping height between the second support tube 14 and the first support tube 13, thereby positioning the height of the second support tube 14. By coordinating the pulling or pushing of the first support tube 13 and / or the second support tube 14, the overall height of the telescopic rigid tube 1 can be adaptively adjusted, thereby adjusting the overall height of the first arc-shaped sleeve 100 and the second arc-shaped sleeve 101.

[0073] It should be noted that the first positioning assembly 12 and the second positioning assembly 15 have the same structure and working principle as the positioning mechanism 4, and the structures of the first positioning assembly 12 and the second positioning assembly 15 will not be described in detail here.

[0074] In an embodiment of the present application, when the bracket 3 is in the closed state, the positioning ring 31 contacts the first positioning assembly 12, that is, the positioning ring 31 is limited by the first positioning assembly 12 and cannot move up further, and the overlapping height between the bracket 3 and the telescopic rigid tube 1 reaches the maximum. When the bracket 3 is in the closed state, the end of the support leg 32 away from the positioning ring 31 is flush with the mother tube 11, so that after the telescopic rigid tube 1 is removed from the mounting hole 103, the bracket 3 and the telescopic rigid tube 1 can be stored in the minimum volume state.

[0075] In an embodiment of the present application, the thicknesses of the first arc-shaped sleeve 100 and the second arc-shaped sleeve 101 are both 5 cm.

[0076] In summary, the present application provides a pressure-sensitive protection sleeve for a gas pipeline, which includes: a first arc-shaped sleeve; a second arc-shaped sleeve for surrounding the first arc-shaped sleeve to form a circular accommodation space; the accommodation space is used to accommodate the gas pipeline; at least two buckles for buckling the two sides of the first arc-shaped sleeve to the second arc-shaped sleeve respectively; a pressure-sensitive detection assembly arranged in the first arc-shaped sleeve and the second arc-shaped sleeve; a telescopic rigid tube detachably arranged in the mounting hole; a bracket sleeved on the telescopic rigid tube and slidable along the telescopic rigid tube to be unfolded and closed; a positioning mechanism movably connected to the bracket and cooperating with the telescopic rigid tube to position the bracket in the unfolded state and the closed state. In the present application, the first arc-shaped sleeve and the second arc-shaped sleeve are designed into a cover-type structure, which is convenient for installing or disassembling around the gas pipeline at any time; the pressure-sensitive detection assembly is used to detect the pressure to judge whether there is gas leakage, and the telescopic rigid tube and the bracket are also used to support the first arc-shaped sleeve and the second arc-shaped sleeve and adjust the support height to adapt to the height of the gas pipeline in different sections, so that the first arc-shaped sleeve and the second arc-shaped sleeve can be positioned around the gas pipeline, while protecting the gas pipeline, preventing the gas pipeline from being damaged by third-party construction, reducing the deformation of the gas pipeline, and detecting whether the gas pipeline is deformed; and it can protect the gas pipeline when gas leaks, avoiding the directly spreading of the leaked gas to the outside, and further improving the gas use safety.
