A multi-layered safety pipe clamp for thermal power boiler pipes

Abstract

This utility model provides a multi-layered safety clamp for thermal power boiler pipelines, comprising: a base, on which a limiting clamp is installed; and a sleeve installed inside the limiting clamp, with multiple support rods evenly spaced between the sleeve and the limiting clamp, each support rod having a rubber layer installed at one end, forming a buffer chamber between the support rods, the sleeve, and the limiting clamp; a detection structure is installed on the inner wall of the limiting clamp. The multi-layered safety clamp for thermal power boiler pipelines provided by this utility model allows leakage of media to be temporarily contained within the buffer chamber, preventing direct discharge to the outside and harm to the environment and workers. Simultaneously, when the media deforms the rubber layer, it contacts a pressure sensor on the mounting plate, transmitting a signal to an alarm. As the rubber layer continues to expand, the buffer chamber contains the expanded rubber layer, preventing it from rupturing under excessive pressure.

Description

Technical Field

[0001] This utility model relates to the field of pipeline protection, and in particular to a multi-protection safety pipe clamp for pipelines of thermal power boilers. Background Technology

[0002] A thermal power plant boiler generates heat by burning fuel, which heats the water inside the boiler into high-temperature, high-pressure steam. The steam drives the turbine to rotate, which in turn drives the generator to produce electricity. It is the heart of a thermal power plant, with a pipeline system running through it, responsible for transporting media such as water and steam.

[0003] When a pipeline system is in operation, the inside of the pipeline must withstand enormous thermal stress, media impact, and vibration. The welded points or connections of the pipeline are prone to damage. If the high-temperature steam and water inside leak to the outside, it can easily cause harm to the environment and workers. Therefore, it is necessary to avoid internal steam leakage.

[0004] Therefore, it is necessary to provide a multi-protection safety pipe clamp for thermal power boiler pipes to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a multi-protection safety pipe clamp for thermal power boiler pipes, which solves the problem that the welding points or connections of the pipes are prone to damage, and the leakage of internal high-temperature steam and water to the outside can easily cause harm to the environment and workers, thus avoiding the problem of internal steam leakage.

[0006] To solve the above technical problems, the present invention provides a multi-protection safety pipe clamp for thermal power boiler pipelines, comprising: a base, on which a limiting clamp is installed, and further comprising: a sleeve installed inside the limiting clamp, and multiple support rods equally spaced between the sleeve and the limiting clamp, each of the multiple support rods having a rubber layer installed at one end, and a buffer chamber formed between the support rods, the sleeve and the limiting clamp;

[0007] The inner wall of the limiting clamp is equipped with a detection structure, and the detection structure is electrically connected to an alarm.

[0008] Preferably, a receiving chamber is provided between one side of the rubber layer and the limiting clamp, and the detection structure is installed in the receiving chamber.

One end of the multiple slide rods is connected to the mounting plate. Multiple pressure sensors are installed at equal intervals on the mounting plate. The pressure sensors are electrically connected to an alarm. The elastic element is installed between the guide tube and the slide rod.

[0010] Preferably, the sleeve surface has multiple through grooves between the multiple support rods, and the multiple through grooves are used to guide the leaked gas into the buffer chamber.

[0015] This utility model provides a multi-protection safety pipe clamp for thermal power boiler pipelines. When the medium leaks, it is discharged into the buffer chamber through the channel for temporary containment, avoiding direct discharge to the outside and causing harm to the environment and workers. At the same time, the medium expands and deforms the rubber layer, which then contacts the pressure sensor on the surface of the mounting plate, transmitting a signal to the alarm to issue a warning. As the rubber layer continues to expand, it pushes the mounting plate to move, and the containment chamber holds the expanded rubber layer, preventing the rubber layer from being subjected to excessive pressure and bursting.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] First Embodiment

[0030] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A multi-protection safety pipe clamp for thermal power boiler pipes includes: a base 1, on which a limiting clamp 11 is installed, and further includes: a sleeve 2 installed inside the limiting clamp 11, a plurality of support rods 21 equally spaced between the sleeve 2 and the limiting clamp 11, a rubber layer 22 installed at one end of each of the plurality of support rods 21, and a buffer chamber 211 formed between the support rods 21, the sleeve 2 and the limiting clamp 11;

[0031] The inner wall of the limiting clamp 11 is equipped with a detection structure 3, and the detection structure 3 is electrically connected to an alarm.

[0032] Before operation, the base 1 is fixed and the pipe is wrapped and secured by the upper and lower limit clamps 11. The connection or welding point is protected by the sleeve 2 and the limit clamps 11 to prevent damage to the pipe caused by external collision. When the pipe is damaged and the internal medium leaks, the medium flows into the buffer chamber 211 through the sleeve 2 for temporary containment. The medium deforms the rubber layer 22 and comes into contact with the detection structure 3. The detection structure 3 detects the leak after being squeezed by the rubber layer 22 and transmits the signal to the alarm to issue a warning. The buffer chamber 211 temporarily contains the leaked medium to prevent the leaked medium from being directly discharged to the outside and to prevent harm to the environment and workers.

[0033] Please refer to the following: Figure 3 , Figure 4 , Figure 6 and Figure 7A receiving chamber 24 is provided between one side of the rubber layer 22 and the limiting clamp 11, and the detection structure 3 is installed in the receiving chamber 24;

[0034] When the leaking medium deforms the rubber layer 22 and comes into contact with the detection structure 3 during operation, an alarm is triggered by the connected alarm. If the medium continues to leak after the alarm is triggered, causing the rubber layer 22 to continue to expand, the expanded rubber layer 22 is contained by the containment chamber 24 to prevent the rubber layer 22 from being subjected to excessive pressure and bursting.

[0035] Please refer to the following: Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The detection structure 3 includes a guide tube 31, a slide rod 32, a mounting plate 33, and an elastic element 34. Multiple guide tubes 31 are installed at equal intervals on one inner wall of the limiting clamp 11. The slide rod 32 is slidably installed inside the guide tube 31. The mounting plate 33 is installed at one end of the multiple slide rods 32. Multiple pressure sensors are installed at equal intervals on the mounting plate 33. The pressure sensors are electrically connected to an alarm. The elastic element 34 is installed between the guide tube 31 and the slide rod 32.

[0036] During operation, when the rubber layer 22 expands, it comes into contact with the pressure sensor on the surface of the mounting plate 33. After receiving the pressure signal, the pressure sensor sends a signal to the alarm device to issue a warning. As the rubber layer 22 continues to expand, it pushes the mounting plate 33 to move. The mounting plate 33 pushes the slide rod 32 to slide into the guide tube 31, leaving the internal space of the receiving chamber 24 for the expanded rubber layer 22. When the leak point repair is completed and the medium inside the buffer chamber 211 is discharged, the rubber layer 22 contracts back to its initial state. At the same time, the elastic element 34 pushes the slide rod 32 to drive the mounting plate 33 back to its initial position.

[0037] Please refer to the following: Figure 2 The sleeve 2 has multiple through grooves 23 located between the multiple support rods 21 on its surface. The multiple through grooves 23 are used to guide the leaked gas into the buffer chamber 211.

[0038] When a leak occurs in the pipeline during operation, the internal medium is discharged into the buffer chamber 211 through the through groove 23 opened on the surface of the sleeve 2.

[0039] Second Embodiment

[0040] Please refer to the following: Figure 2 , Figure 6 and Figure 7The safety clamp for the multiple protection of the thermal power boiler pipeline also includes a protective structure 4. The protective structure 4 is installed on the surface of the sleeve 2 between the multiple support rods 21. The protective structure 4 is used to protect the pipeline.

[0041] In this embodiment, a protective structure 4 is provided on the surface of the sleeve 2 to protect the pipeline and isolate the pipeline surface from the external environment, thereby preventing the internal medium from affecting the outside through the pipeline.

[0042] Please refer to the reference again. Figure 2 , Figure 6 and Figure 7 The protective structure 4 includes a thermal insulation layer 41 and a sound insulation cotton 42. The thermal insulation layer 41 is sleeved on the surface of the sleeve 2, and the sound insulation cotton 42 is installed on the surface of the thermal insulation layer 41.

[0043] During operation, the insulation layer 41 and sound insulation cotton 42 isolate the pipe sleeve from the external environment, preventing the heat of the internal medium from being conducted to the pipe surface, which could cause workers to accidentally touch it and get burned. At the same time, it reduces noise pollution generated by the flow of the medium.

[0044] Please refer to the following: Figure 2 and Figure 6 The bottom of the sleeve 2 and the bottom of the limiting clamp 11 are both equipped with protective pads 25, which are used to protect the pipeline.

[0045] During operation, the protective pad 25 isolates the limiting clamp 11 and the sleeve 2 from the pipeline. The surface of the pipeline 25 is also provided with a through groove 23 to facilitate the flow of the medium. At the same time, it buffers the vibration generated when the medium flows inside the pipeline, so as to avoid the vibration affecting the protection and limiting effect of the limiting clamp 11.

[0046] The working principle of the multi-protection safety pipe clamp for thermal power boiler pipelines provided by this utility model is as follows:

[0047] Before operation, the base 1 is fixed and the pipe is wrapped and secured by the upper and lower limit clamps 11. The connection or welding point is protected by the sleeve 2 and the limit clamps 11. When the pipe is damaged and the internal medium leaks, the internal medium is discharged into the buffer chamber 211 through the channel 23 for temporary containment, preventing the leaked medium from being directly discharged to the outside and preventing harm to the environment and workers. At the same time, the medium expands and deforms the rubber layer 22, which then contacts the pressure sensor on the surface of the mounting plate 33. The pressure sensor transmits a signal to the alarm to issue a warning. If the medium continues to leak and the rubber layer 22 continues to expand, the rubber layer 22 pushes the mounting plate 33 to move. The mounting plate 33 pushes the slide rod 32 to slide into the guide tube 31, and the containment chamber 24 contains the expanded rubber layer 22, preventing the rubber layer 22 from being subjected to excessive pressure and bursting. The insulation layer 41, sound insulation cotton 42, and protective pad 25 are installed. The insulation layer 41 and sound insulation cotton 42 isolate the pipe sleeve from the external environment, preventing the heat of the internal medium from being conducted to the pipe surface and causing workers to accidentally touch it and get burned. At the same time, the noise pollution generated by the flow of the medium is reduced. The protective pad 25 isolates the limiting clamp 11 and the sleeve 2 from the pipe, buffering the vibration generated when the medium flows inside the pipe and preventing the vibration from affecting the protection and limiting effect of the limiting clamp 11.

[0048] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
