Description

Technical Field

[0001] The invention belongs to the technical field of thermometers, and in particular relates to a tube clamp type thermometer. Background Art

[0002] During the operation of industrial pipelines, temperature stability is crucial to both production and safe operation. An industrial pipeline thermometer is a sensor specifically designed to measure pipeline temperature. Its working principle is to utilize the temperature characteristics of a thermistor element to measure temperature.

[0003] Industrial pipeline thermometers have a wide range of applications, including temperature measurement in harsh environments such as high and low temperatures, heat, and humidity. In industrial pipelines, thermometers are often used to monitor temperature changes within the pipeline, ensuring stable temperature and preventing accidents caused by excessively high or low temperatures.

[0004] Before installing an industrial thermometer, you need to select an appropriate installation location based on the actual conditions of the production site. Generally speaking, the thermometer should be installed in areas where temperature fluctuations are large or where temperature control is required, such as equipment inlets and outlets, pipe bends, and the center of storage tanks.

[0005] There are two existing installation methods for industrial thermometers: 1. Direct plug-in Direct insertion is a common installation method for industrial thermometers. This method is quick and easy, requiring the thermometer to be inserted directly into the medium being measured. When inserting the thermometer, aim to insert it approximately two-thirds below the liquid surface to ensure accurate measurement.

[0006] 2. Installed in thermistor device Thermistor devices are another common way to mount industrial thermometers. These devices and industrial thermometers are typically designed as a single piece, allowing them to be mounted in pipes or on equipment surfaces, depending on the application.

[0007] However, the above two thermometer structures have the following problems: 1) Temperature data acquisition is slow. For direct insertion structures, when inserted into the pipe, the sensing area is at the upper end, so the fluid in the pipe takes a long time to pass through. Therefore, the temperature of the pipe is fully transferred to the temperature measurement part before the temperature data can be measured. Therefore, the existing thermometer requires a long response time to obtain temperature data; For the structure in which the thermistor device is installed on the surface of the equipment, first, the end is bent so that the temperature sensing element fits on the outer surface of the pipe. It is generally used to measure the surface temperature of objects, such as the surface of bearings, bushings, pipes, etc. The measurement accuracy is not high and is affected by changes in ambient temperature. The measured parameters are generally not used to control input quantity indicators; secondly, the temperature sensing element needs to be processed into a bent shape, and the temperature sensing element sensor core is easily broken, resulting in a low yield rate. The range of usage scenarios of this structure is not wide, resulting in a small amount of usage; and the structure in which the thermistor device is installed in the pipe has the same problems as the direct insertion structure.

[0008] 2) Both of the above thermometers require mounting brackets during installation. Traditionally, the mounting bracket is welded to the pipe, and the thermometer is fixed to the pipe through the bracket. The welding process may damage the pipe. In particular, when the temperature sensing area needs to be placed in the pipe, the pipe needs to be opened and then sealed and fixed. The installation procedure is quite complicated and may damage the pipe.

[0009] 3) The thermometer's gauge and temperature probe are fixed and cannot be adjusted. The thermometer is generally threaded onto a pipe clamp through a threaded connection structure at the lower end of the gauge, which then secures the thermometer to the pipe. Once the thermometer is threaded onto the pipe clamp, the gauge's orientation is fixed. Since the clamp's threaded connection is not fixed, the gauge's orientation is often uncertain and cannot face people directly. This can be inconvenient for people to read the temperature displayed on the gauge. For example, it is necessary to face the meter head sideways, especially for pipelines with many pipes. The meter heads that could have been installed side by side are all installed to face people directly. People only need to stand at one angle to obtain more data from the meter heads. However, the direction of the meter heads is uncertain, so people need to observe the thermometers on each pipe to obtain data from multiple pipes. Summary of the Invention

[0010] In view of the deficiencies in the prior art, an object of the present invention is to provide a tube clamp thermometer.

[0011] To achieve the aforementioned object of the invention, the technical solutions adopted by the present invention include: A tube clamp thermometer comprises a meter head and a temperature measuring probe, wherein the meter head is threadedly connected to the top end of the temperature measuring probe, and a temperature sensing element is provided in the bottom end of the temperature measuring probe, and further comprises: The heat collecting base is used to abut against the outer surface of the pipeline to quickly collect the pipeline temperature in the measurement area there; and a fixed temperature measuring probe is provided. Specifically, a through hole is provided in the heat collecting base, a reinforcement tube is installed on the outside of the temperature measuring probe, and the temperature measuring probe is fixed to the heat collecting base through the reinforcement tube; the temperature measuring probe part passes through the through hole and is attached to the bottom surface of the heat collecting base, a heat collecting groove for accommodating the temperature measuring probe is provided on the bottom surface of the heat collecting base, a temperature sensing element is provided in the portion of the temperature measuring probe located in the heat collecting groove, and the portion of the temperature measuring probe provided with the temperature sensing element is in contact with the pipeline; the temperature sensing element is inverted in the temperature measuring probe to quickly obtain the pipeline temperature; Pipe clamp mechanism, the collector base can be easily and detachably installed on the pipeline through the pipe clamp mechanism; The steering adjustment mechanism is set between the meter head and the temperature probe rod, and the direction of the meter head is adjusted to face the user to read the temperature data.

[0012] In this invention, the heat-collecting base is designed to fit snugly against the outer surface of the pipe, effectively and rapidly collecting the pipe temperature in the measurement area. The temperature probe partially passes through the heat-collecting base and adheres to the bottom surface. It is then positioned within the heat-collecting trough, allowing the temperature sensor to directly contact the pipe, enabling rapid and accurate temperature measurement. Furthermore, the temperature sensor is inverted within the temperature probe, further improving the speed and accuracy of temperature acquisition and ensuring real-time and reliable temperature measurement.

[0013] In this invention, the thermometer uses a pipe clamp mechanism to facilitate detachable installation between the heat collector base and the pipe, greatly simplifying the installation and removal process and improving work efficiency. Furthermore, the provision of a steering adjustment mechanism allows for flexible adjustment of the meter head's orientation, ensuring that users can read temperature data facing the meter head in the correct direction, enhancing ease of use and comfort. This design not only adapts to the needs of various installation environments but also enhances the user experience.

[0014] Furthermore, the pipe clamp mechanism includes two mounting holes and a pipe clamp provided on the heat collecting base. The two mounting holes are symmetrically provided at both ends of the heat collecting base. Both ends of the pipe clamp pass through the corresponding mounting holes respectively. Both ends of the pipe clamp have an external thread. One end of the pipe clamp passing through the mounting hole is threadedly connected to an adjusting nut, and the external thread is used to match and connect with the adjusting nut.

[0015] Furthermore, at least two groups of tube clamp mechanisms are provided, and the two groups of tube clamp mechanisms are arranged side by side. The two groups of tube clamp mechanisms are symmetrically arranged under the heat collecting base with the through hole as a symmetry point.

[0016] Furthermore, the pipe clamp is U-shaped, has a simple structure, and has excellent fastening performance when fastening the pipeline.

[0017] Furthermore, a fitting concave surface is provided under the heat collecting base, which fits the surface of the pipeline. The heat collecting groove is arranged in the fitting concave surface, which fits the pipeline tightly to facilitate heat collection.

[0018] Furthermore, in order to facilitate grooving and processing, two heat collection grooves are symmetrically opened. During installation, the temperature probe can be installed in any of the heat collection grooves, which is more flexible during installation. At this time, the other heat collection groove is blocked, which can also reduce heat loss.

[0019] Furthermore, the steering adjustment mechanism includes: The sleeve is movably connected to the outside of the temperature probe, and the outer surface of the sleeve has two external threads. A locking nut is installed at the end of the sleeve close to the heat collecting base; A threaded connector, one end of which has a threaded hole threadedly connected to the second external thread, and the threaded connector is installed on the temperature probe by threading it with the casing. The other end has a wire hole for allowing the wire of the temperature sensing element to pass through, and the wire hole diameter is smaller than the threaded hole diameter; the outer surface of the threaded connector has a third external thread, and further, the threaded connector and the meter head are connected by threads or other means for detachable connection; The anti-slip piece is fixed to the end of the temperature measuring probe away from the heat collecting base to prevent the sleeve from detaching from the temperature measuring probe. The outer diameter of the sleeve is smaller than the outer diameter of the anti-slip piece.

[0020] Furthermore, a receiving space for receiving the anti-slip component and a gasket are provided in the threaded connector, and the gasket is located between the anti-slip component and the receiving space.

[0021] Furthermore, a positioning tube is installed in the through hole, and the positioning tube is fixedly installed between the through hole and the temperature measuring probe to strengthen the connection and facilitate the bending of the temperature measuring probe in the later stage.

[0022] Furthermore, the process of inverting the temperature sensing element in the temperature measuring probe includes the following steps: Step 1: Select a three-wire armor wire, where one end of the armor wire is stripped and the other end is ground flat. Step 2: The armor wire is inserted into the magnesium oxide insulation material and formed into an armored part after being shaped. Then, the armored part is inserted into the stainless steel protective tube and formed into an armored thermal resistor lead after multiple drawing, shrinking and annealing. Step 3: First, drill a hole at the axis of the armor, then sandblast into the hole to a depth sufficient to install the temperature sensor. Place the temperature sensor upside down in the hole, weld the two armor wires together and one of the resistance legs of the temperature sensor together using an argon arc welder adjusted to an appropriate current. Step 4: Use an argon arc welder to weld one resistor leg of the temperature sensing element and the other armor wire together. Use an ohmmeter to measure and confirm that they are intact. Pour magnesium oxide powder into the gap between the temperature sensing element and the armor piece and compact it. Then place it in an oven. Step 5: After drying for one and a half hours, apply the insulating material. When the insulating layer is dry, use an argon arc welder to seal one end of the wire that passes through the temperature sensing element, and seal the other end where the temperature sensing element is installed with glue. After the glue is dry, polish it; Step 6: Inspect after polishing and use only if there are no problems.

[0023] Compared with the prior art, the advantages of the present invention include: (1) The present invention provides a pipe clamp type thermometer, wherein the pipe clamp mechanism is cleverly designed. By opening symmetrical mounting holes on the heat collecting base and cooperating with the pipe clamp and the adjusting nut, a stable connection between the heat collecting base and the pipeline is achieved. Both ends of the pipe clamp are provided with matching connections with the adjusting nut, ensuring the superior fastening performance while taking into account the convenience of disassembly. In addition, at least two sets of pipe clamp mechanisms arranged side by side further enhance the stability and reliability of the installation, and the U-shaped pipe clamp also adapts to the installation requirements of pipelines of different diameters; (2) The present invention provides a pipe clamp thermometer with a concave surface design of the heat collecting base, which enables it to fit tightly to the pipe surface. Combined with the setting of the heat collecting groove, it effectively collects the pipe temperature and improves the accuracy of the temperature measurement of the temperature probe. The two heat collecting grooves are symmetrically provided, which not only facilitates the grooving and processing, but also makes the installation of the temperature measuring probe more flexible. The user can install the temperature measuring probe in any heat collecting groove according to actual needs, while the other heat collecting groove is blocked to reduce heat loss. This design is both practical and efficient. (3) The present invention provides a tube clamp thermometer with a steering adjustment mechanism, which allows the direction of the meter head to be flexibly adjusted, ensuring that the user can face the meter head directly to read the temperature data, thereby improving the convenience of use. The combined design of the sleeve, threaded connector, and anti-slip component not only realizes the detachable connection between the meter head and the temperature probe, but also ensures the reliability and stability of the connection through components such as locking nuts and gaskets. At the same time, the positioning tube installed in the through hole further fixes the temperature probe, strengthens the connection, facilitates the subsequent bending operation of the temperature probe, and improves the practicality and durability of the entire thermometer.

Unless otherwise specified, the dimensions, materials, and manufacturing processes of the various components of the tube clamp thermometer in the embodiments of the present invention can be selected according to specific circumstances and are not specifically limited or described herein.

[0033] Furthermore, in order to provide the public with a better understanding of the present invention, some specific details are described in detail in the following detailed description of the present invention, but those skilled in the art can fully understand the present invention without the description of these details.

[0034] Example 1 See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 A tube clamp thermometer comprises a meter head 11 and a temperature measuring probe 12, wherein the bottom end of the temperature measuring probe 12 has a temperature sensing element 13, and further comprises a heat collecting base 14, a tube clamp mechanism 15 and a steering adjustment mechanism 16: Specifically, The heat collecting base 14 is used to abut against the outer surface of the pipeline, so as to quickly collect the pipeline temperature in the measurement area there. At the same time, the heat collecting base 14 is also equivalent to the base of the product of the present invention, and is flexibly installed on or removed from the pipeline through the pipe clamp mechanism 15; the heat collecting base 14 has the function of fixing the temperature measuring probe 12. Specifically, a through hole 22 is provided at the center position of the heat collecting base 14, and a reinforcing tube 32 is installed outside the temperature measuring probe 12, and the temperature measuring probe 12 is fixed to the heat collecting base 14 through the reinforcing tube 32, and the other end of the reinforcing tube 32 is connected to the meter head 11; the temperature measuring probe 12 partially passes through the through hole 22 and is fitted to the bottom surface of the heat collecting base 14, and a heat collecting groove 17 for accommodating the temperature measuring probe 12 is provided on the bottom surface of the heat collecting base 14, and the temperature sensing element 13 is arranged in the part of the temperature measuring probe 12 in the heat collecting groove 17, and the part of the temperature measuring probe 12 provided with the temperature sensing element 13 is in contact with the pipeline; the temperature sensing element 13 is inverted in the temperature measuring probe 12, so as to quickly obtain the pipeline temperature; The heat collecting base 14 can be easily and detachably mounted on the pipe through the pipe clamp mechanism 15; The steering adjustment mechanism 16 is arranged between the meter head 11 and the reinforcement tube 32. The direction of the meter head 11 can always be adjusted to face the user to read the temperature data. The traditional meter head 11 and the temperature probe 12 are either threaded or fixedly connected. The meter head and the temperature probe cannot directly adjust the meter head steering angle. The industrial thermometer composed of the meter head and the temperature probe is fixed to the pipeline with a bracket and has no steering adjustment. Basically, when the industrial thermometer is installed on the pipeline, the tightening procedure is completed and the meter head cannot be adjusted. When the meter head is not facing the user, it affects the user's observation data.

[0035] In the traditional structure between the temperature sensing element and the temperature measuring probe, the temperature sensing element is installed in the temperature measuring probe in the forward direction. If it is directly used for bending, the internal temperature sensing element is very easy to be damaged, so the product yield is low and the application is also narrow. Therefore, based on this, we must improve the process here to adapt to the product of the present invention and improve the yield rate at the same time. The process of flip-mounting the temperature sensing element in the temperature measuring probe includes the following steps: Step 1: Select a three-wire armor wire, where one end of the armor wire is stripped and the other end is ground flat. Step 2: The armor wire is inserted into the magnesium oxide insulation material and formed into an armored part after being shaped. Then, the armored part is inserted into the stainless steel protective tube and formed into an armored thermal resistor lead after multiple drawing, shrinking and annealing. Step 3: First, drill a hole at the axis of the armor, then sandblast into the hole to a depth sufficient to install the temperature sensor. Place the temperature sensor upside down in the hole, weld the two armor wires together and one of the resistance legs of the temperature sensor together using an argon arc welder adjusted to an appropriate current. Step 4: Use an argon arc welder to weld one resistor leg of the temperature sensing element and the other armor wire together. Use an ohmmeter to measure and confirm that they are intact. Pour magnesium oxide powder into the gap between the temperature sensing element and the armor piece and compact it. Then place it in an oven. Step 5: After drying for one and a half hours, apply the insulating material. When the insulating layer is dry, use an argon arc welder to seal one end of the wire that passes through the temperature sensing element, and seal the other end where the temperature sensing element is installed with glue. After the glue is dry, polish it; Step 6: Inspect after polishing and use only if there are no problems.

[0036] Example 2 A tube clamp thermometer comprises a meter head 11 and a temperature measuring probe 12, wherein the bottom end of the temperature measuring probe 12 has a temperature sensing element 13, and further comprises a heat collecting base 14, a tube clamp mechanism 15 and a steering adjustment mechanism 16: specifically, The heat collecting base 14 is used to abut against the outer surface of the pipeline, so as to quickly collect the pipeline temperature in the measurement area there. At the same time, the heat collecting base 14 is also equivalent to the base of the product of the present invention, and is flexibly installed on or removed from the pipeline through the pipe clamp mechanism 15; the heat collecting base 14 has the function of fixing the temperature measuring probe 12. Specifically, a through hole 22 is provided at the center position of the heat collecting base 14, and a reinforcing tube 32 is installed outside the temperature measuring probe 12, and the temperature measuring probe 12 is fixed to the heat collecting base 14 through the reinforcing tube 32, and the other end of the reinforcing tube 32 is connected to the meter head 11; the temperature measuring probe 12 partially passes through the through hole 22 and is fitted to the bottom surface of the heat collecting base 14, and a heat collecting groove 17 for accommodating the temperature measuring probe 12 is provided on the bottom surface of the heat collecting base 14, and the temperature sensing element 13 is arranged in the part of the temperature measuring probe 12 in the heat collecting groove 17, and the part of the temperature measuring probe 12 provided with the temperature sensing element 13 is in contact with the pipeline; the temperature sensing element 13 is inverted in the temperature measuring probe 12, so as to quickly obtain the pipeline temperature; The heat collecting base 14 can be easily and detachably mounted on the pipe through the pipe clamp mechanism 15; Furthermore, the pipe clamp mechanism 15 includes two mounting holes 18 and a pipe clamp 19 provided on the heat collecting base 14. The pipe clamp 19 is used to fasten the pipeline. The two mounting holes 18 are symmetrically provided at both ends of the heat collecting base 14. Both ends of the pipe clamp 19 pass through the corresponding mounting holes 18 respectively. Both ends of the pipe clamp 19 have external threads 20. One end of the pipe clamp 19 passing through the mounting hole 18 is threadedly connected with an adjusting nut 21. The external thread 20 is used to match and connect with the adjusting nut 21. When in use, the pipe clamp 19 is put on the pipeline, and the heat collecting base 14 is grasped so that the corresponding mounting holes 18 are inserted into the two ends of the pipe clamp 19. Then, the two adjusting nuts 21 are used to lock the two ends of the pipe clamp 19 passing through the mounting hole 18 to complete the fastening installation.

[0037] Furthermore, at least two sets of pipe clamps 15 are provided, arranged side by side and spaced apart. The two sets of pipe clamps 15 are symmetrically arranged below the heat collector base 14 with the through-hole 22 as the symmetry point. In other words, the two sets of pipe clamps 15 are located at the two ends of the heat collector base 14. The pipe clamp 19 is preferably U-shaped, as the U-shaped structure is simple and provides excellent tightening performance for pipes. Of course, the pipe clamp 19 can also have a U-shaped interior for accommodating the pipe, with any other exterior structure.

[0038] The steering adjustment mechanism 16 is arranged between the meter head 11 and the reinforcement tube 32. The direction of the meter head 11 can always be adjusted to face the user to read the temperature data. The traditional meter head 11 and the temperature probe 12 are either threaded or fixedly connected. The meter head and the temperature probe cannot directly adjust the meter head steering angle. The industrial thermometer composed of the meter head and the temperature probe is fixed to the pipeline with a bracket and has no steering adjustment. Basically, when the industrial thermometer is installed on the pipeline, after the tightening procedure is completed, the meter head is located where it is and cannot be adjusted. When the meter head is not facing the user, it affects the user's observation data.

[0039] Furthermore, the steering adjustment mechanism 16 includes a sleeve 23, a threaded connector 24, and an anti-slip member 25: The sleeve 23 is movably sleeved on the outside of the reinforcement tube 32. The sleeve 23 can move outside the reinforcement tube 32 along the axis of the reinforcement tube 32. The outer surface of the sleeve 23 has an external thread 26. A locking nut 33 is installed on the end of the sleeve 23 close to the heat collecting base 14. A threaded hole 27 is provided at one end of the threaded connector 24 for threaded connection with the second external thread 26. The threaded connector 24 is installed on the temperature probe 12 by being threadedly connected to the sleeve 23. A wire hole is provided at the other end to allow the wire of the temperature sensing element 13 to pass through. The diameter of the wire hole is smaller than the diameter of the threaded hole 27. The outer surface of the threaded connector 24 has a third external thread 28. The threaded connector 24 and the meter head 11 are connected by thread or other means for detachable connection. The third external thread 28 is used for threaded connection with the meter head 11. The anti-slip component 25 is fixed to one end of the reinforcing tube 32 away from the heat collecting base 14 to prevent the sleeve 23 from detaching from the reinforcing tube 32 . The outer diameter of the sleeve 23 is smaller than the outer diameter of the anti-slip component 25 .

[0040] Furthermore, an accommodating space 28 for accommodating the anti-slip component 25 and a gasket 29 are provided in the threaded connector 24 . The gasket 29 is located between the anti-slip component 25 and the accommodating space 28 .

[0041] Furthermore, the heat collecting base 14 has a concave surface 30 that fits against the pipe surface. The heat collecting groove 17 is set in the concave surface 30, tightly fitting the pipe to facilitate heat collection. To facilitate grooving and processing, two heat collecting grooves 17 are symmetrically provided, centered on the through hole 22. During installation, the temperature probe 12 can be installed in any of the heat collecting grooves 17. This structure is more flexible during installation, and the other heat collecting groove 17 is blocked at this time, which can also reduce heat loss.

[0042] Furthermore, a positioning tube 31 is installed in the through hole 22 , and the positioning tube 31 is fixed between the through hole 22 and the temperature probe 12 to strengthen the connection and facilitate the subsequent bending process of the temperature probe 12 located under the heat collecting base 14 .

[0043] The traditional structure between the temperature sensing element and the temperature measuring probe is that the temperature sensing element is installed in the temperature measuring probe in the forward direction. If it is directly used for bending, the internal temperature sensing element is very easy to be damaged, so the product yield is low and the application is also narrow. Therefore, based on this, we must improve the process here to adapt to the product of the present invention and improve the yield rate at the same time. Figure 4 The process of inverting the temperature sensing element into the temperature probe includes the following steps: Step 1: Select a three-wire armor wire, where one end of the armor wire is stripped and the other end is ground flat. Step 2: The armor wire is inserted into the magnesium oxide insulation material and formed into an armored part after being shaped. Then, the armored part is inserted into the stainless steel protective tube and formed into an armored thermal resistor lead after multiple drawing, shrinking and annealing. Step 3: First, drill a hole at the axis of the armor, then sandblast into the hole to a depth sufficient to install the temperature sensor. Place the temperature sensor upside down in the hole, weld the two armor wires together and one of the resistance legs of the temperature sensor together using an argon arc welder adjusted to an appropriate current. Step 4: Use an argon arc welder to weld one resistor leg of the temperature sensing element and the other armor wire together. Use an ohmmeter to measure and confirm that they are intact. Pour magnesium oxide powder into the gap between the temperature sensing element and the armor piece and compact it. Then place it in an oven. Step 5: After drying for one and a half hours, apply the insulating material. When the insulating layer is dry, use an argon arc welder to seal one end of the wire that passes through the temperature sensing element, and seal the other end where the temperature sensing element is installed with glue. After the glue is dry, polish it; Step 6: Inspect after polishing and use only if there are no problems.

[0044] Working principle: The heat collecting base serves as the mounting base for the thermometer. Its concave surface tightly contacts the outer surface of the pipe, collecting the pipe temperature within the measurement area. The temperature sensing element at the bottom of the temperature probe is nestled in a heat collecting groove on the underside of the heat collecting base. This groove allows the sensing element to directly contact the pipe, quickly and accurately measuring the pipe temperature without losing heat, ensuring fast and accurate measurement.

[0045] The pipe clamp mechanism is used to flexibly install or remove the heat collector base (and the entire thermometer) on the pipeline. The pipe clamp mechanism consists of two symmetrical mounting holes on the heat collector base and a U-shaped pipe clamp.

[0046] During installation, the pipe clamp is placed over the pipe. The collector base is then grasped and the corresponding mounting holes are inserted into the ends of the pipe clamp. Next, two nuts are used to tighten the ends of the pipe clamp protruding from the mounting holes to complete the installation. The use of at least two sets of pipe clamps, spaced apart and arranged side by side, enhances installation stability and reliability.

[0047] The steering adjustment mechanism is arranged between the meter head and the reinforcement tube, and is used to adjust the direction of the meter head so that it always faces the user, making it easier to read temperature data.

[0048] When in use, the rotating threaded connector is connected to the sleeve thread, and the meter head and the reinforcement tube are also installed and connected. Then the meter head can be directly rotated to adjust the direction of the data displayed on the meter head so that it faces the user.
