Abstract
Description
Technical Field
[0001] This utility model belongs to the field of temperature monitoring technology, specifically relating to a temperature monitoring device for monitoring thermal pipelines. Background Technology
[0002] In numerous fields such as industrial production, construction engineering, and energy transmission, real-time and accurate monitoring of the temperature of the medium inside pipelines is a crucial element in ensuring the safe and stable operation of the system. Temperature sensors, as the core equipment for achieving this monitoring function, directly affect the accuracy and reliability of the measurement results through their installation method and stability.
[0003] Currently, the common installation method for pipeline temperature detection devices mainly uses clamps for fixing. The clamps are tightened with bolts to attach the sensor to the pipeline surface. Although this method can achieve a certain degree of fixation for the temperature detection device, it has many drawbacks. When the pipeline experiences thermal expansion and contraction, the bolts of the clamps are prone to loosening. This is because the thermal expansion and contraction of the pipeline will cause the relative position between the clamp and the pipeline to change. Under frequent displacement and vibration, the tightening force of the bolts gradually decreases, causing the clamp to fail to maintain effective fixation of the sensor. Once the clamp loosens, the fit between the temperature detection device and the pipeline surface will decrease, which will affect the heat transfer efficiency and cause the temperature data measured by the temperature detection device to deviate. This will prevent the device from accurately reflecting the true temperature of the medium inside the pipeline, posing potential risks to the operation and control of the system.
[0004] Meanwhile, some installation structures lack an effective mechanism to cope with the thermal expansion and contraction of pipelines. When the pipeline expands or contracts due to temperature changes, the existing installation structure cannot adaptively adjust the fit between the temperature detection device and the pipeline, resulting in gaps or excessive compression between the temperature detection device and the pipeline. The presence of gaps increases thermal resistance and hinders heat transfer; while excessive compression may damage the sensitive elements inside the temperature detection device, affecting its normal working performance and shortening the lifespan of its sensor.
[0005] In addition, traditional installation methods also have inconveniences in the installation and maintenance process. The installation of the clamp requires the insertion of bolts on both sides, which is a relatively cumbersome operation. Moreover, when the sensor needs to be repaired or replaced, disassembling the clamp also requires a lot of time and effort, which reduces maintenance efficiency and increases operation and maintenance costs. Therefore, a temperature monitoring device for monitoring thermal pipelines is needed to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a temperature monitoring device for monitoring thermal pipelines, so as to solve the problems mentioned in the background art.
[0007] To achieve the above object, the present utility model provides the following technical solutions: A temperature monitoring device for thermal pipeline monitoring, including an L-shaped fixing bracket and a thermal pipeline. A base is rotatably provided at the bottom of the L-shaped fixing bracket. The L-shaped fixing bracket and the base together form a "C"-shaped frame body and are arranged outside the thermal pipeline. An installation block is fixedly installed at one end of the L-shaped fixing bracket. A first elastic telescopic rod is installed on the installation block. A patch-type temperature monitoring device for temperature monitoring of the thermal pipeline is installed at the bottom end of the first elastic telescopic rod. When the diameter size of the thermal pipeline changes during thermal expansion and contraction, it will press against the first elastic telescopic rod for adaptive elastic expansion and contraction, so that the patch-type temperature monitoring device can always adhere to the surface of the thermal pipeline for temperature detection.
[0008] As a preferred embodiment, two second elastic telescopic rods are also installed on the installation block. A pressing block is fixedly installed at the bottom end of each second elastic telescopic rod. The two pressing blocks are respectively located on both sides of the patch-type temperature monitoring device. The shape of each pressing block and the patch-type temperature monitoring device fits the surface of the thermal pipeline.
[0009] As a preferred embodiment, the first elastic telescopic rod includes a first telescopic shaft, a first telescopic frame and a first spring. The first telescopic shaft is telescopically connected in the first telescopic frame and its bottom end is connected to the patch-type temperature monitoring device. The first spring is arranged in the first telescopic frame and the top end of the first telescopic shaft abuts against its bottom end.
[0010] As a preferred embodiment, the second elastic telescopic rod includes a second telescopic shaft, a second telescopic frame and a second spring. The second telescopic shaft is telescopically connected in the second telescopic frame and its bottom end is connected to the patch-type temperature monitoring device. The second spring is arranged in the second telescopic frame and the top end of the second telescopic shaft abuts against its bottom end.
[0011] As a preferred embodiment, the elastic force of the second spring is greater than that of the first spring. When the diameter size of the thermal pipeline changes during thermal expansion and contraction, the pressing block at the bottom end of the second elastic telescopic rod will bear a greater pressing and adapting force due to the high elastic force of the second spring, and配合底座能够实现对热力管道稳固的夹持。(这里原文表述不太准确,推测是想说“并配合底座实现对热力管道的稳固夹持”)
[0012] As a preferred embodiment, extension connecting blocks are fixedly provided on one side of the base and the installation block. The two extension connecting blocks are connected by a bolt rod and a nut. The "C"-shaped frame body formed by the L-shaped fixing bracket and the base can be rotatably installed and fixed on the thermal pipeline through the base, and a "口"-shaped structure is formed by unilateral connection of the bolt rod and the nut. (这里原文“口”字型结构直接用中文表述不太合适,可考虑用类似“square-shaped structure”等英文表述,但按照要求保留原文特殊字符)
[0013] Compared with the prior art, the beneficial effects of the present utility model are:
[0014] The utility model is composed of an L-shaped fixing frame and a base, and the "C"-shaped frame body formed by them surrounds the outside of the heating pipeline. Different from the traditional clamp fixing method, the "C"-shaped frame body can achieve self-adaptive clamping fixation through the elastic pressing of its top structure, avoiding the problem that the bolts on the traditional clamp become loose due to the thermal expansion and contraction of the pipeline. The first elastic telescopic rod with elastic telescopic function set on the mounting block can adaptively perform elastic telescopic according to the change of the diameter size caused by the thermal expansion and contraction of the heating pipeline, ensuring that the patch-type temperature monitoring device always closely adheres to the surface of the heating pipeline, effectively avoiding the reduction of heat transfer efficiency and measurement deviation caused by the decrease of the adhesion degree, and at the same time preventing the damage to the sensitive components inside the sensor caused by excessive extrusion, significantly improving the accuracy and reliability of temperature monitoring, and prolonging the service life of the sensor.
[0015] In the utility model, the combined use of the first elastic telescopic rod and the second elastic telescopic rod greatly improves the adaptability to the thermal expansion and contraction of the heating pipeline and the monitoring stability. The first elastic telescopic rod can flexibly respond to the slight diameter change of the heating pipeline, ensuring that the patch-type temperature monitoring device always closely adheres to the pipeline surface, providing a reliable basis for temperature detection. And the second elastic telescopic rod, with its second spring with a large elastic force, when the heating pipeline undergoes significant thermal expansion and contraction, the pressing block at the bottom can bear a large pressing adaptation force, and together with the base, realizes the stable clamping of the heating pipeline. This design enables the whole device to ensure the accuracy of temperature monitoring and maintain the structural stability when dealing with different degrees of pipeline deformation, effectively avoiding problems such as sensor loosening and measurement deviation caused by pipeline deformation.
[0016] In the utility model, the extension connection blocks arranged on one side of the base and the mounting block, in cooperation with bolts and nuts, bring great convenience to the overall installation. During installation, the "C"-shaped frame body composed of the L-shaped fixing frame and the base can be rotated through the base and sleeved on the heating pipeline, and then the bolt rod is threadedly connected between the two extension connection blocks and tightened with nuts. After unilateral connection, a stable "square" - shaped fixing structure is formed.
[0017] This installation method does not require complex operations and professional tools, and is more labor-saving than the bilateral bolt installation of the traditional clamp. The installer can quickly and accurately complete the fixation of the device on the heating pipeline, greatly shortening the installation time and reducing the installation difficulty. At the same time, the stability of this structure ensures that the temperature monitoring device will not easily loosen or shift during the operation of the heating pipeline, guaranteeing the continuous and stable progress of temperature monitoring work. .

[0023] The present invention will be further described below with reference to the embodiments.
[0024] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.
[0025] Please see Figure 1-4, the utility model provides a temperature monitoring device for thermal pipeline monitoring, which includes an L-shaped fixing frame 1 and a thermal pipeline 2. A base 3 is rotatably arranged at the bottom of the L-shaped fixing frame 1. The L-shaped fixing frame 1 and the base 3 are generally in a "C"-shaped frame and are arranged outside the thermal pipeline 2. An installation block 4 is fixedly installed at one end of the L-shaped fixing frame 1. A first elastic telescopic rod 5 is installed on the installation block 4. A patch-type temperature monitoring device 6 for monitoring the temperature of the thermal pipeline 2 is installed at the bottom end of the first elastic telescopic rod 5. When the diameter size of the thermal pipeline 2 changes due to thermal expansion and contraction, it will press against the first elastic telescopic rod 5 for adaptive elastic expansion and contraction, so that the patch-type temperature monitoring device 6 can always be attached to the surface of the thermal pipeline 2 for temperature detection. The "C"-shaped frame composed of the L-shaped fixing frame 1 and the base 3 surrounds the outside of the thermal pipeline 2. Different from the traditional clamp fixing method, the "C"-shaped frame can achieve adaptive clamping and fixing through the elastic pressing of its top structure, avoiding the problem that the bolts on the traditional clamp become loose due to the thermal expansion and contraction of the pipeline. The first elastic telescopic rod 5 with elastic expansion and contraction arranged on the installation block 4 can adaptively perform elastic expansion and contraction according to the diameter size change caused by the thermal expansion and contraction of the thermal pipeline 2, ensuring that the patch-type temperature monitoring device 6 is always closely attached to the surface of the thermal pipeline 2, effectively avoiding the reduction of heat transfer efficiency and measurement deviation caused by the decrease in the degree of fit, and at the same time preventing damage to the sensitive components inside the sensor caused by excessive extrusion, significantly improving the accuracy and reliability of temperature monitoring and extending the service life of the sensor.
[0026] [[ID=३]]Two second elastic telescopic rods 7 are also installed on the installation block 4. A pressing block 8 is fixedly installed at the bottom end of each second elastic telescopic rod 7. The two pressing blocks 8 are respectively located on both sides of the patch-type temperature monitoring device 6. The shape of each pressing block 8 and the patch-type temperature monitoring device 6 fits the surface of the thermal pipeline 2.
[0027] The first elastic telescopic rod 5 includes a first telescopic shaft 51, a first telescopic frame 52 and a first spring 53. The first telescopic shaft 51 is telescopically connected in the first telescopic frame 52 and its bottom end is connected to the patch-type temperature monitoring device 6. The first spring 53 is arranged in the first telescopic frame 52 and the top end of the first telescopic shaft 51 abuts against its bottom end.
[0028] The second elastic telescopic rod 7 includes a second telescopic shaft 71, a second telescopic frame 72 and a second spring 73. The second telescopic shaft 71 is telescopically connected in the second telescopic frame 72 and its bottom end is connected to the patch-type temperature monitoring device 6. The second spring 73 is arranged in the second telescopic frame 72 and the top end of the second telescopic shaft 71 abuts against its bottom end.
[0029] The elastic force of the second spring 73 is greater than that of the first spring 53. When the diameter of the thermal pipeline 2 changes due to thermal expansion and contraction, the pressing block 8 at the bottom of the second elastic telescopic rod 7 will bear a greater pressing adaptation force due to the high elastic force of the second spring 73, and cooperate with the base 3 to achieve stable clamping of the thermal pipeline 2. The combined use of the first elastic telescopic rod 5 and the second elastic telescopic rod 7 greatly improves the adaptability to thermal expansion and contraction of the thermal pipeline 2 and the monitoring stability. The first elastic telescopic rod 5 can flexibly respond to the subtle diameter changes of the thermal pipeline 2, ensuring that the patch-type temperature monitoring device 6 is always closely attached to the pipeline surface, providing a reliable basis for temperature detection. The second elastic telescopic rod 7, with its second spring 73 having a large elastic force, when the thermal pipeline 2 undergoes significant thermal expansion and contraction, the pressing block 8 at the bottom can bear a greater pressing adaptation force, and together with the base 3, achieve stable clamping of the thermal pipeline 2. This design enables the entire device to ensure the accuracy of temperature monitoring and maintain the stability of the structure when dealing with pipeline deformations of different degrees, effectively avoiding problems such as sensor loosening and measurement deviation caused by pipeline deformation.
[0030] Extension connection blocks 9 are fixedly arranged on one side of both the base 3 and the mounting block 4. The two extension connection blocks 9 are connected by a bolt rod 10 and a nut 11. The "C"-shaped frame formed by the L-shaped fixing frame 1 and the base 3 can be rotationally installed and fixed on the thermal pipeline 2 through the base 3, and a "square" structure is formed by the unilateral connection of the bolt rod 10 and the nut 11. During installation, the "C"-shaped frame formed by the L-shaped fixing frame 1 and the base 3 can be rotated and sleeved on the thermal pipeline 2 through the base 3. Subsequently, the bolt rod 10 is threadedly connected between the two extension connection blocks 9, and the nut 11 is tightened. After unilateral connection, a stable "square" fixing structure is formed. This installation method does not require complex operations and professional tools, and is more labor-saving compared to the bilateral bolt installation of traditional clamps. Installers can quickly and accurately complete the fixing of the device on the thermal pipeline 2, significantly shortening the installation time and reducing the installation difficulty. At the same time, the stability of this structure ensures that the temperature monitoring device will not loosen or shift easily during the operation of the thermal pipeline 2, guaranteeing the continuous and stable progress of temperature monitoring work.
[0031] The working principle and usage process of the present utility model: When actually installing and using the temperature monitoring device for thermal pipeline monitoring, first rotate and open the base 3 rotatably arranged at the bottom of the L-shaped fixing frame 1, and sleeve the "C"-shaped frame on the outside of the thermal pipeline 2. Then, pass the bolt rod 10 through the extension connection blocks 9 on one side of the base 3 and the mounting block 4, and tighten it with the nut 11 to form a stable "square" fixing structure to complete the installation and fixing of the device;
[0032] When the heating pipe 2 is running normally and the temperature is relatively stable, the first spring 53 of the first elastic telescopic rod 5 is in a natural state or a slightly compressed state, so that the patch-type temperature monitoring device 6 is tightly attached to the surface of the heating pipe 2 to monitor the pipe temperature in real time.
[0033] When the diameter of the pipe changes due to thermal expansion and contraction, the first elastic telescopic rod 5 and the second elastic telescopic rod 7 work together. The first telescopic shaft 51 of the first elastic telescopic rod 5 extends and retracts within the first telescopic frame 52, and the first spring 53 is correspondingly compressed or extended, so that the patch-type temperature monitoring device 6 always fits tightly against the surface of the heat pipe 2 to ensure the accuracy of temperature monitoring. At the same time, the second elastic telescopic rod 7, with the large elasticity of its second spring 73, always maintains a large resistance force. On the one hand, the pressure block 8 at the bottom of the second elastic telescopic rod 7 cooperates with the base 3 to achieve a stable clamping of the heat pipe 2, ensuring the stability of the entire device structure; on the other hand, the second elastic telescopic rod 7 bears the main resistance force, which can ensure that the patch-type temperature monitoring device 6 will not be subjected to excessive clamping rebound force, so that it can continuously monitor the temperature of the heat pipe 2 in a stable state.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
