Description

Technical Field

[0001] The invention relates to the field of infrared temperature measurement, in particular to a handheld metal conductor dynamic temperature measuring instrument. Background Art

[0002] Currently, handheld dynamic thermometers for metal conductors are widely used in industrial production, equipment maintenance, and scientific research, providing a convenient and efficient solution for temperature measurement. For example, a K-type thermocouple, based on the Seebeck effect, uses two conductors of different compositions to form a closed circuit. When a temperature gradient exists between the two ends, a temperature-dependent electromotive force is generated in the circuit, which in turn determines the temperature of the measured medium. This handheld design allows users to conveniently measure temperature at various locations, providing powerful support for temperature monitoring and control.

[0003] However, existing handheld dynamic temperature sensors for metal conductors primarily rely on thermocouples for temperature measurement, which presents certain limitations. For one thing, thermocouples are generally less accurate than resistance temperature detectors (RTDs) or thermistors, with measurement accuracy typically limited to within 1°C to 2°C, making them difficult to meet the demands of high-precision temperature measurement. Furthermore, thermocouples require cold-junction compensation to ensure that the temperature of the hot junction, rather than the cold junction, is measured, increasing device complexity and maintenance costs. Furthermore, thermocouple signals can be susceptible to electromagnetic interference, particularly in industrial environments, which can affect measurement accuracy. Summary of the Invention

In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0030] Reference Figures 1-4The present embodiment provides a handheld metal conductor dynamic temperature measuring instrument, comprising a clamping component 1, which includes a shell 11 and a large wheel 12 mounted on the shell 11, with two small wheels 13 symmetrically arranged about the large wheel 12, each small wheel 13 corresponding to a rotating arm 14, and the two rotating arms 14 are controlled by a power member 15 to rotate simultaneously; a thermocouple temperature measuring component 2, which includes a control component 21 located inside the shell 11, the control component 21 is electrically connected to the two small wheels 13, and a touch screen 22 is provided on one side of the shell 11 and is electrically connected to the control component 21; an infrared temperature measuring component 3, wherein a receiving cavity 31 is provided on the back side of the shell 11, and a flap 32 that folds outward is provided on the receiving cavity 31, and an external socket 33 is provided on the flap 32, and an infrared sensor 34 is plugged into the external socket 33, and a switching component 35 is provided in the flap 32, and the switching component 35 drives the flap 32 to connect with the power member 15, so that the flap 32 and the two small wheels 13 move simultaneously. The interior of the housing 11 is divided into two parts, the upper and lower parts, wherein the power component 15 and the infrared temperature measuring component 3 are located in the upper part, and the thermocouple temperature measuring component 2 is located in the lower part.

[0031] In this embodiment, the housing 11 forms the main body of the device, providing structural support and protection. A large wheel 12 is mounted at the top center of the housing 11 and is used to cooperate with two small wheels 13 to clamp the metal conductor (cable core) and also serves as the hot end of the thermocouple. The two small wheels 13 are symmetrically positioned on either side of the large wheel 12, each corresponding to a rotating arm 14. A power element 15 controls the simultaneous rotation of the two rotating arms 14 to adjust the spacing between the small and large wheels 13 and 12. Clamping the metal conductor: The power element 15 controls the two rotating arms 14 to open or close the gap between the small and large wheels 13 and 12, thereby clamping and releasing the metal conductor.

[0032] Control unit 21 is located inside housing 11 and electrically connected to large wheel 12. Touch screen 22 is located on one side of housing 11 and electrically connected to control unit 21 for operation and display of measurement results. Control unit 21 detects the electromotive force of the metal conductor, processing the temperature measurement results and displaying them directly on touch screen 22 for real-time monitoring by the operator.

[0033] The receiving chamber 31 is provided on the back of the shell 11 for accommodating the infrared temperature measuring component 3. The flap 32 is provided on the receiving chamber 31 and can be folded outward to open. The infrared sensor 34 is plugged into the external socket 33 for electrically connecting with the control component 21 for infrared temperature measurement. The switching component 35 is provided in the flap 32 for driving the flap 32 to be connected to the power component 15, so as to realize the synchronous movement of the flap 32 and the two small wheels 13. Infrared temperature measurement: infrared temperature measurement is performed by aligning the infrared sensor 34 with the metal conductor. Flap 32 control: when the infrared sensor 34 is plugged into the flap 32, the switching component 35 is connected to the power component 15, so as to realize the synchronous movement of the flap 32 and the two small wheels 13, and ensure that the infrared sensor 34 is aligned with the metal conductor when measuring temperature.

[0034] Flexible installation is achieved through the external jack 33: Specifically, by setting the external jack 33 on the flap 32, the infrared sensor 34 can be quickly connected and removed. This design allows users to flexibly choose whether to install the infrared sensor 34 according to actual needs, thereby improving the adaptability and portability of the device.

[0035] Convenient operation is achieved through the design of the flap 32: the specific flap 32 can be folded outward to facilitate the installation and removal of the infrared sensor 34. A switching part 35 is provided in the flap 32, which is connected to the power part 15 of the equipment to ensure the synchronous movement of the flap 32 and the small wheel 13, so that the infrared sensor 34 can be accurately aligned with the metal conductor when measuring temperature.

[0036] Improve temperature measurement accuracy through multi-sensor fusion: Specifically, by adding an infrared sensor 34, the device can simultaneously use thermocouple temperature measurement and infrared temperature measurement to achieve multi-sensor data fusion. This fusion can improve the accuracy and reliability of temperature measurement and reduce the errors that may be caused by single sensor measurement.

[0037] Cover more scenarios through the combination of non-contact and contact: Thermocouple temperature measurement is suitable for contact measurement, while infrared temperature measurement is suitable for non-contact measurement. The combination of the two temperature measurement methods can cover a wider range of measurement scenarios, especially in high-temperature, dangerous or difficult-to-reach environments. Infrared temperature measurement can provide an additional measurement method to ensure the comprehensiveness and accuracy of the data.

[0038] Improve data credibility through real-time monitoring and feedback: The specific device can display the results of the two temperature measurement methods in real time through the internal control part 21 and the touch screen 22. The user can intuitively compare and verify the data, thereby improving the credibility and reliability of the measurement.

[0039] The device can flexibly switch between thermocouple temperature measurement and infrared temperature measurement according to actual measurement needs. Users can choose the most appropriate temperature measurement method according to specific circumstances, which improves the applicability and flexibility of the device. Users can view the results of the two temperature measurement methods in real time through the touch screen 22, compare and verify, and ensure the accuracy and reliability of the measurement data. The device is easy to operate, and users can easily control the temperature measurement process through the touch screen 22, which improves measurement efficiency and operational convenience.

[0040] Reference Figure 4-Figure 6 The power member 15 includes a toothed plate 151 positioned between the two rotating arms 14. First teeth 152 are provided on either side of the toothed plate 151, meshing with second teeth 141 provided on the outer wall of the rotating end of the rotating arm 14. A first telescopic cylinder 153 is provided on the inner side of the toothed plate 151 to push the toothed plate 151 outward. The large wheel 12 is rotatably positioned at the top center of the housing 11. Two small wheels 13 are located on the same horizontal plane as the large wheel 12. The small wheels 13 and the large wheel 12 cooperate to clamp the metal conductor. Notches 111 are provided on both sides of the housing 11, and the rotating arm 14 rotates within these notches 111.

[0041] It should be noted that the tooth plate 151 is located between the two rotating arms 14. First teeth 152 are provided on both sides of the tooth plate 151. The tooth plate 151 meshes with second teeth 141 provided on the outer wall of the rotating end of the rotating arm 14 through the first teeth 152, achieving the linkage of the two rotating arms 14 and the synchronous movement of the two small wheels 13. Notches 111 are provided on both sides of the housing 11. The rotating arms 14 rotate within the notches 111. The design of the notches 111 allows the rotating arms 14 to rotate smoothly when clamping and releasing the metal conductor. The two small wheels 13 and the large wheel 12 are located on the same horizontal plane. The small wheels 13 and the large wheel 12 cooperate to clamp the metal conductor (cable core).

[0042] Inside the toothed plate 151, a first telescopic cylinder 153 is mounted. This cylinder comprises a cylinder and a piston rod located within the cylinder. The piston rod is secured to the toothed plate 151, with a spring positioned between the two for retracting the piston rod. The first telescopic cylinder 153 retracts the toothed plate 151, thereby rotating the pivot arm 14 and the small wheel 13, shortening the distance between the two small wheels 13 and the large wheel 12.

[0043] The large wheel 12 is rotatably disposed at the top center of the housing 11 and is electrically connected to the control component 21 . The large wheel 12 serves as the hot end of the thermocouple and cooperates with the control component 21 to measure the temperature of the thermocouple component.

[0044] The process of clamping the metal conductor is as follows: when any of the small wheels 13 is pulled to move backward away from the large wheel 12, the small wheel 13 is mounted on the rotating arm 14, driving the rotating arm 14 to rotate. The second tooth 141 provided on the fixed end of the rotating arm 14 drives the first tooth 152 on the side of the tooth plate 151 meshing with it, causing the tooth plate 151 to move outward. The outward movement of the tooth plate 151 drives the other rotating arm 14 and the small wheel 13 symmetrically arranged on the other side to rotate, and the gap between the two small wheels 13 and the large wheel 12 is simultaneously widened, making it easier to wrap the metal conductor around the surface of the large wheel 12 after half a circle. As the tooth plate 151 moves outward, the first telescopic cylinder 153 extends, thereby releasing the control of the small wheel 13. The first telescopic cylinder 153 shortens and resets under the action of the internal strong spring, and the tooth plate 151 moves inward and resets, driving the rotating arms 14 and small wheels 13 on both sides to reset. Both small wheels 13 are in contact with the large wheel 12, achieving the clamping and fixing of the metal conductor.

[0045] The effects are as follows: (1) Stable clamping: The mechanical structure design ensures that the metal conductor is firmly clamped, preventing displacement or loosening during the temperature measurement process. (2) Easy operation: By pulling the small wheel 13 and the linkage of the first telescopic cylinder 153, the metal conductor can be quickly clamped and released, improving operational efficiency. Through the above design, the handheld metal conductor dynamic temperature measuring instrument can achieve stable clamping of the metal conductor, providing reliable mechanical support for subsequent temperature measurement operations.

[0046] Reference Figure 4-Figure 6 The lower end of the flap 32 is pivotally mounted within the receiving chamber 31 via a switching member 35, allowing it to flip downward and open. When the flap 32 is open, the infrared sensor 34 located on the flap 32 is aligned with the metal conductor wrapped around the outer wall of the large wheel 12. The switching member 35 includes a double-ended telescopic cylinder 351 located within the flap 32. Friction wheels 352 are mounted at both ends of the double-ended telescopic cylinder 351. The friction wheels 352 are mounted on one end of a rotating rod 353, the other end of which is mounted on the inner wall of the housing 11 via a bearing. An air passage 354 is provided within the flap 32. One end of the air passage 354 communicates with the interior of the double-ended telescopic cylinder 351, and the other end is provided with an elastic return plug 355, which is compressed by the infrared sensor 34. The surface of the toothed plate 151 is provided with two symmetrical rows of third teeth 154. Each third tooth 154 is provided with a corresponding first gear 155. The first gear 155 is rotatably mounted within the housing 11 via a rod 156. The first gear 155 engages with the friction wheel 352. The double-ended telescopic cylinder 351 includes a sleeve 3511 and two piston rods 3512 mounted at either end of the sleeve 3511. A first spring 3513 is provided between the two piston rods 3512 to pull the two piston rods 3512 toward each other. The midpoint of the sleeve 3511 is connected to the air passage 354. A one-way ratchet structure is provided between the piston rods 3512 and the friction wheel 352.

[0047] It should be noted that the lower end of the flap 32 is rotatably arranged in the receiving cavity 31 through the switching member 35, and the flap 32 can be flipped downward and opened with the switching member 35 at its lower end as the axis. When the flap 32 is opened, the infrared sensor 34 inserted on the flap 32 is aligned with the metal conductor wrapped around the outer wall of the large wheel 12, thereby realizing temperature measurement of the metal conductor.

[0048] The switching member 35 includes a double-headed telescopic cylinder 351 part and an air duct 354 part located inside the flap 32, wherein one end of the air duct 354 is connected to the inside of the double-headed telescopic cylinder 351, and the other end is provided with an elastic reset plug 355. The entire plug body of the elastic reset plug 355 is set to be a soft long strip, and a spring is provided at its end to push it to reset. When it is squeezed by the infrared sensor 34, the plug body contracts into the air duct 354 and squeezes the air in the air duct 354, causing it to enter the double-headed telescopic cylinder 351, pushing the piston rods 3512 at both ends of the double-headed telescopic cylinder 351 to expand.

[0049] The double-ended telescopic cylinder 351 includes a sleeve 3511 and two piston rods 3512 mounted at either end of the sleeve 3511. A first spring 3513 is disposed between the two piston rods 3512 to pull the two piston rods 3512 toward each other. The midpoint of the sleeve 3511 is connected to the air passage 354. One end of each piston rod 3512 is connected to a friction wheel 352 via a one-way ratchet structure. The friction wheel 352 can only drive the piston rod 3512 to rotate in one direction, thereby enabling the flap 32 to flip open. A keyway is provided between the piston rod 3512 and the flap 32, enabling the piston rod 3512 to telescope within the flap 32. When the piston rod 3512 moves outward, it engages the friction wheel 352 with the first gear 155, causing the first gear 155 to reverse, thereby driving the flap 32 to flip open.

[0050] Two symmetrical rows of third teeth 154 are provided on the lower surface of the tooth plate 151. Each third tooth 154 is correspondingly provided with a first gear 155. The first gear 155 is rotatably arranged in the housing 11 through the rod body 156. When the first gear 155 is in contact with the friction wheel 352, it drives the flap 32 to rotate and open.

[0051] Install the infrared sensor 34: Manually flip the flap 32 outward, and use the switching piece 35 at the lower end of the flap 32 as the axis to flip the upper end downward, keeping the flap 32 horizontal, exposing the external socket 33 on the flap 32, and plug the socket on the infrared sensor 34 into the external socket 33. The external socket 33 is an interface such as USB and is electrically connected to the control component 21, thereby realizing the electrical connection between the infrared sensor 34 and the control component 21.

[0052] During the installation process, when the infrared sensor 34 is plugged into the external socket 33, the elastic reset plug 355 on the flap 32 is pressed down at the same time. The elastic reset plug 355 squeezes the air in the airway 354 and squeezes it to the center of the double-headed telescopic cylinder 351. The two piston rods 3512 at both ends of the sleeve 3511 of the double-headed telescopic cylinder 351 overcome the pulling force of the first spring 3513 and move outward, so that the friction wheel 352 at the other end of the piston rod 3512 fits with the first gear 155. Afterwards, when the small wheel 13 is pulled to move away from the large wheel 12 for clamping operation, the tooth plate 151 moves outward and can drive the first gear 155 to rotate through the third tooth 154 on its surface. The first gear 155 drives the friction wheel 352 in contact with it to reverse, and drives the flap 32 that cooperates with the keyway of the piston rod 3512 to rotate, thereby rotating the flap 32 to a horizontal state, flipping open the infrared sensor 34 installed on the flap 32, and aligning it with the metal conductor.

[0053] Since the friction wheel 352 and the piston rod 3512 are connected by a one-way ratchet, when the small wheel 13 is released and reset, the flap 32 is not reset. Only after the temperature measurement is completed, the flap 32 is manually flipped upwards, the receiving chamber 31 is re-closed and the infrared sensor 34 is stored in the receiving chamber 31. The reason for setting up the form of unilateral opening of the flap 32 is to avoid the staff forgetting to turn on the infrared measurement, resulting in missing data during measurement and the need to re-measure. The fully automatic system can avoid this problem. After the test is completed, it will be unfolded so that the staff can definitely see it. The entire equipment is irregular and inconvenient to store, so it can definitely be found and closed.

[0054] Effect: After adding the infrared temperature measurement component 3, the equipment can use both thermocouple temperature measurement and infrared temperature measurement to improve the accuracy and applicability of temperature measurement; whether to use infrared temperature measurement can be selected according to needs, which is suitable for different measurement environments and needs; the installation and use of the infrared temperature measurement component 3 is simple and convenient, and does not require complicated settings and adjustments.

[0055] The external socket 33 is configured as a USB interface or a TC interface, etc., and the external socket 33 is electrically connected to the control component 21 through a cable.

[0056] It should be noted that: a plurality of external jacks 33 are provided on the shell 11, one of which is provided on the flap 32 and is specifically used for connecting to the infrared sensor 34. The other external jacks 33 are used to connect to other devices for data transmission and other functions. The external jacks 33 are set to common interface types such as USB interface or TC interface to ensure that the device is compatible with a variety of external devices and sensors. These interfaces are electrically connected to the control component 21 through cables to realize signal transmission between the external device and the internal control component 21 of the device. This design not only improves the versatility of the device, but also ensures flexibility and adaptability in different application scenarios. Through these interfaces, users can easily connect various external devices, such as infrared sensors 34, data acquisition modules, etc., thereby expanding the functions and application scope of the device.

[0057] Reference Figures 1-6 , the working process and effect description of the handheld metal conductor dynamic temperature meter.

[0058] Clamping the metal conductor: Pull any small wheel 13 to move it backward away from the large wheel 12. The small wheel 13 is installed on the rotating arm 14, driving the rotating arm 14 to rotate. The second tooth 141 set at the fixed end of the rotating arm 14 drives the first tooth 152 on the side of the tooth plate 151 that meshes with it, causing the tooth plate 151 to move outward. The outward movement of the tooth plate 151 drives the other rotating arm 14 and the small wheel 13 on the other side to rotate, and synchronously increases the distance between the two small wheels 13 and the large wheel 12, making it easier to wrap the metal conductor around the surface of the large wheel 12 after half a circle. As the tooth plate 151 moves outward, the first telescopic cylinder 153 extends, thereby releasing the control of the small wheel 13. The first telescopic cylinder 153 shortens and resets under the action of the internal strong spring, and the tooth plate 151 moves inward and resets, driving the rotating arms 14 and small wheels 13 on both sides to reset. Both small wheels 13 are in contact with the large wheel 12, achieving the clamping and fixing of the metal conductor. The mechanical structure is designed to ensure that the metal conductor is firmly clamped to avoid displacement or loosening during the temperature measurement process.

[0059] When measuring temperature with a thermocouple: the staff starts the thermocouple temperature measuring component 2 through the touch screen, the internal control component 21 is electrically connected to the two contacts of the thermocouple, the hot end of the thermocouple (large wheel 12) contacts the metal conductor to be measured, and the cold end is maintained at a known reference temperature, generating an electromotive force. The control component 21 detects the electromotive force and performs signal processing and calibration. The measurement results are directly displayed on the touch screen after processing.

[0060] When using infrared temperature measurement simultaneously: first clamp the metal conductor, continue to pull the two small wheels 13 away from the large wheel 12. As the tooth plate 151 moves outward, the third tooth 154 on the surface of the tooth plate 151 also moves outward, driving the first gear 155 engaged with it to rotate. This causes the first gear 155 to rub against the friction wheel 352, and the friction wheel 352 rotates, driving the piston rod 3512 to rotate. The keyway between the piston rod 3512 and the flap 32 drives the flap 32 to rotate on the rotating rod 353, flipping the flap 32 outward to open it to a horizontal position, and aligning the infrared sensor 34 with the metal conductor to measure the temperature. When the temperature measurement is completed, the flap 32 is manually folded upward, and the infrared sensor 34 is stored in the receiving chamber 31.
