Description

Technical Field

[0001] This utility model relates to the field of digital thermometer technology, and in particular to a digital high-precision standard thermometer. Background Technology

[0002] Digital thermometers operate primarily based on the physical characteristics of semiconductor temperature-sensing elements, combined with precision signal processing and digital conversion technology to achieve accurate temperature measurement. Utilizing the significant temperature-dependent changes in the resistance of semiconductor materials, or based on the Seebeck effect, a small voltage (thermoelectric potential) is generated at the temperature difference between two different metal junctions. Temperature is measured by calculating the temperature difference and other effects through voltage measurement, and then the signal is amplified to obtain precise temperature data.

[0003] Digital thermometers, with their high sensitivity, are frequently used in medical and industrial fields. In industrial applications, substances with temperature are often transported through pipelines. Excessively high or low pipeline temperatures can threaten pipeline safety. Therefore, real-time monitoring of pipeline temperatures is essential.

[0004] Currently available digital thermometers are generally not specifically designed for monitoring pipe temperatures, which may make it inconvenient to mount the thermometer on the pipe. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a digital high-precision standard thermometer to solve the problem of the inconvenience of fixing the thermometer to the surface of the pipe in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides a digital high-precision standard thermometer, including a digital thermometer body, an arc-shaped groove at the end of the digital thermometer body, and a heat conduction part on the inner wall of the arc-shaped groove.

[0007] The end of the arc-shaped groove is provided with a fixing clamp, which is detachably installed at the end of the arc-shaped groove by fasteners.

[0008] A clamping groove is provided between the fixing clamp and the arc-shaped groove.

[0009] Preferably, the heat conduction part protrudes from the inner wall of the arc-shaped groove, and the heat conduction part is a semiconductor thermistor.

[0010] Preferably, a temperature display screen is provided at the end of the digital thermometer body away from the heat conduction part, and a control button is provided on the side of the digital thermometer body.

[0011] Preferably, an infrared thermometer is provided on the top of the digital thermometer body, and the detection direction of the infrared thermometer faces the heat conduction part.

[0012] Preferably, the top of the digital thermometer body is provided with a sloping curved surface, the infrared thermometer is located at the high point of the sloping curved surface, and the infrared thermometer is recessed into the interior of the sloping curved surface.

[0013] Preferably, an anti-interference cover is provided above the slope surface to cover the infrared thermometer. The bottom of the anti-interference cover is in contact with the top of the slope surface, and an opening is provided at the end of the anti-interference cover facing the heat conduction part.

[0014] Preferably, the anti-interference cover is detachably mounted on top of the ramp surface.

[0015] Preferably, the infrared thermometer has two fixed sliding grooves symmetrically opened on both sides, and the bottom of the anti-interference cover has two fixed guide rails that are adapted to the fixed sliding grooves.

[0016] The fixed guide rail is inserted into the interior of the fixed slide groove from one end.

[0017] Preferably, the bottom of the fixed slide groove has the same curvature as the top of the ramp surface, and limit grooves are provided on both sides of the bottom of the fixed slide groove;

[0018] The bottom of the fixed guide rail is provided with limiting strips that protrude to both sides. The limiting strips cooperate with the limiting grooves to limit the anti-interference cover.

[0019] As described above, the digital high-precision standard thermometer of this invention has the following beneficial effects:

[0020] 1. This utility model provides an arc-shaped groove at the end of the digital thermometer body and a heat conduction part inside the arc-shaped groove. The heat conduction part fits into the outer surface of the pipe, and the digital thermometer body is fixed to the pipe by a fixing clamp that cooperates with the arc-shaped groove. This allows for direct temperature monitoring of the outer surface of the pipe, achieving the effect of conveniently fixing the digital thermometer body to the outer surface of the pipe.

[0021] The heat conduction part is directly attached to the outer surface of the pipe, which can improve the efficiency of temperature conduction and reduce the loss of temperature during the conduction process, thus reducing the accuracy. At the same time, the heat conduction part has less contact with the outside air, which can further reduce the temperature loss and achieve the effect of improving the accuracy of temperature detection.

[0022] Furthermore, this device is directly fixed to the pipeline, occupying only a small amount of space around the pipeline, thus achieving the effect of being applicable to complex pipeline environments.

[0023] 2. This utility model sets an infrared thermometer on the top of the digital thermometer body, and performs non-contact measurement on the outer surface of the pipe through the infrared thermometer. The measurement data of the heat conduction part and the infrared thermometer are compared and verified. Even after the heat conduction part is affected by external interference and damage, it can still perform effective measurement, and the accuracy of data measurement is improved by mutual verification of the data.

[0024] 3. This utility model reduces interference from ambient heat radiation by covering the outer surface of the infrared thermometer with an anti-interference cover, thereby improving the accuracy of the infrared thermometer measurement. Furthermore, the anti-interference cover is detachably mounted on the top of the sloping curved surface, allowing it to be installed and removed as needed.

[0025] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. Attached Figure Description

[0034] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0035] Please see Figures 1 to 6It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0036] like Figure 1 As shown, this utility model provides a digital high-precision standard thermometer, including a digital thermometer body 1. The digital thermometer body 1 internally houses a power supply, a signal conditioning device, a high-precision analog-to-digital converter, etc., for converting temperature information into digital information. The components and their connection methods in the digital thermometer body 1 are all existing technologies and will not be described in detail. An arc-shaped groove 2 is provided at the end of the digital thermometer body 1. During installation, the interior of the arc-shaped groove 2 is in contact with the outer surface of the pipe. A heat conduction part 3 is provided on the inner wall of the arc-shaped groove 2. Through the contact between the heat conduction part 3 and the outer surface of the pipe, the temperature of the outer surface of the pipe can be directly sensed.

[0037] A fixing clamp 4 is provided at the end of the arc-shaped groove 2. The fixing clamp 4 is detachably installed at the end of the arc-shaped groove 2 by bolts or other fasteners. A clamping groove is provided between the fixing clamp 4 and the arc-shaped groove 2, which fixes the digital thermometer body 1 to the outer surface of the pipe by pressure and friction. When disassembling and assembling the equipment, the fixing clamp 4 can be separated from the arc-shaped groove 2 for easy disassembly and assembly.

[0038] To facilitate data transmission, the digital thermometer body 1 can integrate a wireless signal transmission device, which can remotely transmit data to a terminal device for display.

[0039] like Figure 1As shown, in some embodiments, the heat conduction part 3 of this invention slightly protrudes from the inner wall of the arc-shaped groove 2, thereby allowing the heat conduction part 3 to directly contact the outer surface of the pipe. This avoids the inner wall of the arc-shaped groove 2 absorbing heat preferentially over the heat conduction part 3, which could lead to inaccurate temperature measurement. The slight protrusion of the heat conduction part 3 minimizes the gap between the arc-shaped groove 2 and the outer surface of the pipe. This prevents external air from flowing between the arc-shaped groove 2 and the pipe, thus avoiding inaccurate temperature detection by the heat conduction part 3. The heat conduction part 3 is a semiconductor thermistor; when heat is conducted to the heat conduction part 3, the resistance of the heat conduction part 3 changes directly. This prevents heat from being transferred over long distances to the interior of the digital thermometer body 1, which could lead to inaccurate data.

[0040] like Figure 2 As shown, in some embodiments, a temperature display screen 6 is provided at the end of the digital thermometer body 1 away from the heat conduction part 3. The temperature display screen 6 is located on the side, so that the manager can directly observe the temperature data. A control button 5 is provided on the side of the digital thermometer body 1, which is also used to facilitate the manager to turn the device on and off.

[0041] like Figure 3 and Figure 4 As shown, in some embodiments, an infrared thermometer 8 is provided on the top of the digital thermometer body 1 of this invention, with the detection direction of the infrared thermometer 8 facing the heat conduction part 3. The infrared thermometer 8 allows for non-contact measurement of the pipe temperature, preventing data loss when the heat conduction part 3 is severely interfered with or damaged. Furthermore, the data measured by the heat conduction part 3 and the infrared thermometer 8 can be cross-verified, resulting in more accurate temperature measurements.

[0042] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the top of the digital thermometer body 1 of this invention is provided with a sloping curved surface 7, and the infrared thermometer 8 is positioned at the high point of the sloping curved surface 7, so that the measuring angle of the infrared thermometer 8 is parallel to the heat conduction part 3. This also prevents the fixing clamp 4 from obstructing the infrared thermometer 8. The infrared thermometer 8 is recessed into the interior of the sloping curved surface 7 to protect it. This prevents the sensing head of the infrared thermometer 8 from being impacted or worn during transportation and installation, thus avoiding the inability to perform measurements normally.

[0043] like Figure 3 and Figure 4As shown, in some embodiments, an anti-interference cover 9 is provided above the inclined curved surface 7 of this invention to cover the infrared thermometer 8. The bottom of the anti-interference cover 9 is in contact with the top of the inclined curved surface 7, and an opening is provided at the end of the anti-interference cover 9 facing the heat conduction part 3. This is used to further protect the infrared thermometer 8. During measurement, the infrared rays of the infrared thermometer 8 are emitted from the opening of the anti-interference cover 9 towards the pipe and reflected and received. At the same time, it can also reduce the interference of heat radiation around the pipe on the infrared thermometer 8, and improve the measurement accuracy of the infrared thermometer 8.

[0044] like Figure 3 As shown, in some embodiments, the anti-interference cover 9 of this invention is detachably mounted on the top of the sloping curved surface 7. This allows the anti-interference cover 9 to be installed and removed according to the user's needs. Simultaneously, it avoids the inability to install in confined spaces due to obstruction by the anti-interference cover 9.

[0045] like Figure 3 , Figure 5 and Figure 6 As shown in some embodiments, the infrared thermometer 8 of this invention has two symmetrically arranged fixed grooves 10 on both sides, and the bottom of the anti-interference cover 9 has two fixed guide rails 11 that are adapted to the fixed grooves 10. The fixed guide rails 11 are inserted into the interior of the fixed grooves 10 from one end. Installing the anti-interference cover 9 by plugging it in improves the ease of installation and removal of the anti-interference cover 9.

[0046] like Figure 5 and Figure 6 As shown, in some embodiments, the bottom of the fixed groove 10 of this invention has the same curvature as the top of the ramp surface 7, and the curvature of the fixed guide rail 11 is the same as the curvature of the bottom of the fixed groove 10. This allows the fixed guide rail 11 to be inserted into the fixed groove 10 completely and snugly, improving the stability of the connection.

[0047] Limiting grooves are provided on both sides of the bottom of the fixed slide 10. The bottom of the fixed guide rail 11 is provided with limiting strips that protrude to both sides. The limiting strips cooperate with the limiting grooves to limit the anti-interference cover 9. Through the cooperation of the limiting grooves and limiting strips, the anti-interference cover 9 can be further prevented from detaching from the top of the slope surface 7.

[0048] In summary, the digital high-precision standard thermometer of this utility model provides an arc-shaped groove 2 at the end of the digital thermometer body 1, and a heat conduction part 3 is provided inside the arc-shaped groove 2. The heat conduction part 3 is attached to the outer surface of the pipe, and the digital thermometer body 1 is fixed to the pipe by the fixing clamp 4 cooperating with the arc-shaped groove 2. This allows for direct temperature monitoring of the outer surface of the pipe, achieving the effect of conveniently fixing the digital thermometer body 1 to the outer surface of the pipe.

[0049] The heat conduction part 3 is directly attached to the outer surface of the pipe, which can improve the efficiency of temperature conduction and reduce the loss of temperature during the conduction process, thus reducing the accuracy. At the same time, the heat conduction part 3 has less contact with the outside air, which can further reduce the temperature loss and achieve the effect of improving the accuracy of temperature detection.

[0050] Furthermore, this device is directly fixed to the pipeline, occupying only a small amount of space around the pipeline, making it suitable for complex pipeline environments.

[0051] This invention provides an infrared thermometer 8 installed on the top of the digital thermometer body 1. The infrared thermometer 8 performs non-contact measurement on the outer surface of the pipe. The measurement data of the heat conduction part 3 and the infrared thermometer 8 are compared and verified. Even after the heat conduction part 3 is subjected to external interference or damage, it can still perform effective measurement. The accuracy of the data measurement is improved through mutual verification of the data.

[0052] This invention reduces interference from ambient heat radiation on the infrared thermometer 8 by covering its outer surface with an anti-interference cover 9, thereby improving the accuracy of the infrared thermometer 8. Furthermore, the anti-interference cover 9 is detachably mounted on the top of the sloping curved surface 7, allowing it to be installed and removed as needed.

[0053] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0054] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
