[0035] The present invention provides the following embodiments:

[0036] Example 1

[0037] This invention provides a thermal pipeline insulation device, such as... Figure 1 , Figure 9 , Figure 10 , Figure 11 As shown, a thermal pipeline insulation device includes a thermal main pipeline 1, an insulation mechanism 2 on the thermal main pipeline 1, a plurality of bearing arcs 11 arranged at intervals on the insulation mechanism 2, an expansion mechanism 5 on the bearing arcs 11, protective limiting mechanisms 7 on both sides of the bearing arcs 11, and protective alarm mechanisms 9 on both sides of the insulation mechanism 2.

[0038] The main heat pipe 1 is responsible for transporting high-temperature hot water or steam and other heat media. The insulation mechanism 2 is directly wrapped around the main heat pipe 1. Through the thermal insulation performance of the insulation material (such as rock wool, polyurethane, etc.), the heat transfer from the main pipe to the outside is reduced, thus reducing heat loss. At the same time, it prevents the outer surface temperature of the pipe from exceeding the specified limit temperature. The load-bearing arc rings 11 are arranged at intervals on the insulation mechanism 2. The expansion and contraction mechanisms 5 at both ends are mainly responsible for the length expansion or displacement of the components of the insulation mechanism 2 caused by temperature changes (thermal expansion and contraction). When the components inside the insulation mechanism 2 extend, the expansion and contraction mechanisms 5 can extend synchronously; when they contract due to cold, the expansion and contraction mechanisms 5 can compress and reset, preventing the components inside the insulation mechanism 2 from deforming and tearing or crushing, thus ensuring the integrity of the insulation mechanism 2. In addition, the expansion and contraction mechanisms 5 ensure shock absorption when the main heat pipe 1 is displaced due to vibration. The protective limiting mechanism 7 is set on both sides of the load-bearing arc rings 11 to limit the maximum deformation range of the expansion and contraction mechanisms 5. When the expansion and contraction exceeds the safety threshold, the protective limit mechanism 7 will prevent the expansion and contraction mechanism 5 from continuing to deform through mechanical limit. The protective alarm mechanism 9 is installed on both sides of the insulation mechanism 2 to promptly alarm when non-operating personnel approach the insulation mechanism 2.

[0039] The protective alarm mechanism 9 includes several warning lines 91, which are symmetrically arranged in pairs on both sides of the main heat pipe 1. An alarm structure 92 is provided between each of the warning lines 91 and connected to it.

[0040] When a non-operating person approaches the insulation mechanism 2, the warning line prevents them from getting close to the insulation mechanism. When they touch the warning line 91 and cause a certain disturbance to the warning line 91, the alarm structure 92 will generate an alarm.

[0041] The alarm structure 92 includes an alarm sleeve 921, which is bolted to a base platform 922. The base platform 922 is bolted to a bearing ring 11. A fixed anchor hook 923 is fixedly connected to the side of the alarm sleeve 921 and is connected to the left warning line 91. An alarm 924 is provided at one end of the alarm sleeve 921. A connecting rod 925 is slidably connected inside the alarm sleeve 921. A compression elastic element 926 is provided between the connecting rod 925 and the alarm sleeve 921. A permanent magnet 927 is fixedly connected to one end of the connecting rod 925 and abuts against the alarm 924. The other end of the connecting rod 925 is fixedly connected to the right warning line 91. A tensioning structure 10 is provided on the side of the alarm sleeve 921 near the alarm 924.

[0042] A warning line 91 is provided between the two alarm structures 92. One end of the warning line 91 is fixedly connected to the fixed anchor hook 923 of one alarm structure 92, and the other end is fixedly connected to the connecting rod 925 of the other alarm structure 92. If a person touches the warning line 91, a tool hits the warning line 91, or a foreign object gets entangled and causes the warning line 91 to come close to the main heat pipe 1, the warning line 91 will exceed the limit of the tensioning structure 10 and pull the connecting rod 925, causing the permanent magnet 927 at the end of the connecting rod 925 to disengage from the alarm 924, and the reed in the alarm 924 will... When the magnetic force disappears, a circuit break signal is generated in the pipe, which in turn generates an audible and visual alarm. At the same time, the connecting rod 925 squeezes and compresses the elastic element 926 until the connecting rod 925 moves a certain distance and comes into contact with the alarm sleeve 921. This ensures that the warning line 91 still provides some obstruction to personnel, preventing them from touching the main heat pipe 1. When personnel move away from the warning line 91, the connecting rod 925 resets under the action of the elastic element 926, causing the permanent magnet 927 to come into contact with the alarm 924. The reed switch in the alarm 924 generates a circuit signal due to the magnetic force, and the audible and visual alarm stops simultaneously.

[0043] In the above technical solution, the insulation mechanism 2 directly reduces heat loss, maintains a long-term stable insulation effect, and reduces energy waste during heat transmission. The telescopic mechanism 5 can flexibly cope with thermal expansion and contraction, and together with the protective limit mechanism 7, avoids excessive deformation, reduces the mechanical stress on the components in the insulation mechanism 2, reduces the risk of cracking caused by deformation, extends the service life of the components in the insulation mechanism 2, and reduces the impact force on the main heat pipe 1 during vibration. The protective alarm mechanism 9 can promptly warn non-operating personnel to approach the main heat pipe 1, preventing personnel from accidentally touching the surface of the insulation mechanism 2 and causing burns.

[0044] The perimeter monitoring ring formed by the warning line 91 can cover the key areas around the main heat pipe 1, and promptly warn of abnormal intrusions such as personnel misoperation and object collision, avoiding the risk of burns caused by non-operating personnel touching the pipe. Furthermore, the connecting rod 925 and the alarm 924 can work continuously under the action of the compression elastic element 926, ensuring high working stability and strong continuity of the alarm structure 92.

[0045] Example 2

[0046] Based on Example 1, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the insulation mechanism 2 includes several heat insulation modules 3, which are arranged axially along the main heat pipe 1. The heat insulation modules 3 are nested and overlapped with each other. A moisture-proof layer 21 is provided outside the heat insulation modules 3. The moisture-proof layer 21 is spirally wound on the heat insulation modules 3. A protective shell 22 is provided outside the moisture-proof layer 21, which surrounds and covers the moisture-proof layer 21.

[0047] Multiple insulation modules 3 are arranged axially along the main heat pipe 1. The modules are nested and overlapped (the ends of adjacent modules are designed with matching concave and convex structures) to form a continuous insulation layer, avoiding the thermal bridging effect caused by axial through-slots. At the same time, the nested structure allows the modules to undergo slight relative displacement with the thermal expansion and contraction of the pipe, preventing the insulation layer from cracking due to stress concentration. The moisture-proof layer 21 is wrapped around the insulation module 3 in a spiral winding manner. The extensibility of the spiral structure adapts to the axial expansion and contraction of the pipe, blocking external moisture from entering the insulation layer. The protective shell 22 surrounds the moisture-proof layer 21 and resists external impact and environmental aging through its own rigidity, protecting the integrity of the internal insulation module 3 and the moisture-proof layer 21.

[0048] The heat insulation module 3 includes two heat insulation pipe shells 31, which are symmetrically fixedly connected to the main heat pipe 1. Each of the two heat insulation pipe shells 31 is provided with several nested grooves 32, and each of the nested grooves 32 is fitted with a tie structure 4.

[0049] The heat insulation module 3 consists of two symmetrical heat insulation tube shells 31. During installation, they are radially fastened together along the main heat pipe 1 and fixed by the nesting grooves 32 on the heat insulation tube shell 31 and the tie structure 4.

[0050] The tie structure 4 includes two pipe clamps 41, which are symmetrically fitted into the nesting groove 32. One end of the two pipe clamps 41 is hinged to each other, and the other end of the two pipe clamps 41 is fixedly connected to a tie hook 42 and a tie clip 43, respectively. A assisted pull ring 44 is rotatably connected to the tie clip 43. A connecting rod 45 is provided at the center of the assisted pull ring 44. Both ends of the connecting rod 45 are fixedly connected to the assisted pull ring 44. A tie connecting rod 46 is provided between the assisted pull ring 44 and the tie hook 42. One end of the tie connecting rod 46 is threaded onto the connecting rod 45, and the other end of the tie connecting rod 46 is rotatably connected to a hanging ring 47, which is fitted onto the tie hook 42.

[0051] Two clamps 41 of the tie structure 4 are fitted along the nesting groove 32. One end of the clamp 41 is connected by a hinge to open and close, making it easy to fasten onto the heat insulation shell 31. The tie hook 42 at the other end cooperates with the tie rod 46 and the hanging ring 47. By rotating the auxiliary pull ring 44, the tie hook 42 and the hanging ring 47 can achieve nesting tension and unlocking. When it is necessary to adjust the tension, the screwing depth of the tie rod 46 on the connecting rod 45 is adjusted to increase or decrease the tension.

[0052] In the above technical solution, the insulation module 3 forms a seamless insulation layer through "left and right symmetrical fastening + axial nesting overlap", avoiding the gap thermal bridges caused by traditional splicing; the tight fixation of the tie structure 4 ensures that the insulation shell 31 is in close contact with the pipe surface, reducing air convection heat dissipation and improving insulation efficiency; the moisture-proof layer 21 adopts a spiral winding method, which, compared with traditional overlap bonding, has an adaptive sealing performance as the pipe expands and contracts, effectively blocking water vapor intrusion; the tie rod 46 of the tie structure 4 is threaded to the connecting rod 45, and the tension of the tie structure 4 can be adjusted according to the actual situation to ensure the adaptability of the tie structure 4 to the insulation module 3.

[0053] Example 3

[0054] Based on Example 2, such as Figure 6 , Figure 7 As shown, the telescopic mechanism 5 includes a bearing plate 51, which is fixedly connected to the bottom of the bearing arc ring 11. A shock-absorbing structure 6 is provided below the bearing plate 51. An insulating corrugated pipe 52 is fixedly connected inside the bearing arc ring 11. The insulating corrugated pipe 52 is sleeved on the heat insulation module 3. Both ends of the insulating corrugated pipe 52 are provided with sockets 53. The sockets 53 are sleeved on the protective shell 22. A sealing ring is provided between the sockets 53 and the protective shell 22.

[0055] The heat insulation corrugated pipe 52 is sleeved on the outside of the heat insulation module 3, and its two ends are connected to the protective shell 22 through the socket 53. The expansion and contraction of the heat insulation corrugated pipe 52 can accommodate the axial displacement caused by the thermal expansion and contraction of the protective shell 22.

[0056] The damping structure 6 includes a damping seat 61, with spacer legs 62 below the damping seat 61. The spacer legs 62 slide relative to the damping seat 61. Two cylindrical sliders 63 are symmetrically fixedly connected to the top of the spacer legs 62. Two longitudinal grooves 64 are symmetrically provided at the bottom of the damping seat 61. The two cylindrical sliders 63 are slidably connected in the two longitudinal grooves 64 respectively. Compression elastic elements 65 are provided between the two ends of the two cylindrical sliders 63 and the damping seat 61. A transverse groove 66 is provided at the top of the damping seat 61. A transverse cylindrical slider 67 is slidably connected in the transverse groove 66. A bearing plate 51 is fixedly connected to the top of the transverse cylindrical slider 67. Compression elastic elements 68 are provided between the two ends of the transverse cylindrical slider 67 and the damping seat 61.

[0057] The bearing arc ring 11 fixes the insulated corrugated pipe 53 and transfers its load to the bearing plate 51. The shock absorption structure 6 below the bearing plate 51 absorbs pipe vibration or external impact through bidirectional elastic buffer. When the pipe generates axial vibration, the cylindrical slider 63 at the top of the spacer leg 62 slides in the longitudinal groove 64 of the shock absorber seat 61. The cylindrical slider 63 compresses or stretches the compression elastic element 65 on both sides, converting kinetic energy into elastic potential energy, thereby achieving longitudinal vibration attenuation. When the pipe generates lateral vibration, the transverse cylindrical slider 67 at the bottom of the bearing arc ring 11 slides in the transverse groove 66 of the shock absorber seat 61. The transverse cylindrical slider 67 compresses or stretches the compression elastic element 68 on both sides, buffering lateral stress and preventing the insulated corrugated pipe 53 from being damaged due to excessive radial force.

[0058] The corrugated structure of the insulated corrugated pipe 52 in the above technical solution, combined with the sealing design of the socket 53, can avoid stress problems caused by thermal expansion and contraction of the protective sleeve 22. The longitudinal and transverse elastic buffer structure of the vibration structure can effectively absorb pipeline vibration and external impact, reduce the risk of fatigue aging of the pipeline caused by vibration and loosening of the insulation module 3.

[0059] Example 4

[0060] Based on Example 1, such as Figure 6 , Figure 8 As shown, the protective limiting mechanism 7 includes a protective ring 71, which is located on the side of the bearing arc ring 11. The protective ring 71 is bolted to the bearing arc ring 11. A rubber ring 72 is provided on the end face of the protective ring 71, and the rubber ring 72 is fixed to the end face of the protective ring 71 by bolts. A limiting structure 8 is provided on the side of the protective ring 71.

[0061] The protective ring 71 is fixed to the side of the bearing arc ring 11 by bolts, forming an annular barrier around the pipe to prevent external impacts from acting on the connection between the insulated corrugated pipe 53 and the protective sleeve 22. At the same time, the design of the rubber ring 72 prevents impurities from entering the connection between the insulated corrugated pipe 53 and the protective sleeve 22.

[0062] The limiting structure 8 includes several limiting clips 81, which are arranged in a ring on the side of the protective ring 71. The limiting clips 81 are all fixedly connected to the protective ring 71. A limiting connecting rod 82 is fixedly connected to each of the limiting clips 81. A blocking plate 83 is sleeved on the limiting connecting rod 82. The blocking plate 83 is fixedly connected to the protective sleeve 22.

[0063] The limiting clips 81 are distributed in a ring on the side of the protective ring 71. They cooperate with the blocking plates 83 on the protective sleeve 22 through the limiting connecting rod 82 to achieve controllable constraint on the radial displacement between the heat insulation corrugated pipe 53 and the protective sleeve 22. This ensures that the heat insulation corrugated pipe 53 cannot detach from the protective sleeve 22, and that when the protective sleeve 22 undergoes axial displacement due to thermal expansion and contraction, the protective sleeve 22 can move along the limiting connecting rod 82.

[0064] In the above technical solution, the rigid barrier of the protective ring 71 and the flexible seal of the rubber ring 72 are combined to resist external mechanical impact and external impurities. The ring-shaped limiting structure 8 strictly controls the radial displacement of the pipeline within the design range, avoiding the failure of the connection between the heat-insulating corrugated pipe 53 and the protective sleeve 22 due to excessive displacement.

[0065] Example 5

[0066] Based on Example 1, such as Figure 9 , Figure 12 As shown, the tensioning structure 10 includes a tensioning sleeve 101, which is bolted to the foundation platform 922. A tensioning rod 102 is slidably connected inside the tensioning sleeve 101. A compression elastic element 103 is provided between the tensioning rod 102 and the tensioning sleeve 101. A rotating wheel 104 is rotatably connected to the end of the tensioning rod 102, and a warning line 91 is wound on the rotating wheel 104.

[0067] The compression elastic element 5 103 inside the tensioning sleeve 101 always applies a pushing force to the tensioning rod 102, keeping the warning line 91 on the rotating wheel 104 in a taut state. When the warning line 91 is touched, the warning line 91 applies pressure to the rotating wheel, causing the tensioning rod 102 to slide along the tensioning sleeve 101 and squeeze the compression elastic element 5 103 until the tensioning rod 102 can no longer slide. Then, the warning line 91 pulls the connecting rod 925. During this process, the tensioning structure 10 serves as a pressing redundancy for the warning line 91.

[0068] In the above technical solution, the tensioning structure 10 can ensure the tension of the warning line 91 and provide timely feedback on personnel touching the warning line 91, while also maintaining a certain amount of redundancy to prevent the warning line 91 from being triggered by slight accidental contact due to natural factors such as wind.

[0069] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
