Description

[0002] At present, handheld metal conductor dynamic temperature measuring instruments are widely used in industrial production, equipment maintenance, scientific research and testing, etc., providing a convenient and efficient solution for temperature measurement. Taking the K-type thermocouple as an example, it is based on the Seebeck effect. It uses two conductors of different materials to form a closed loop. When there is a temperature gradient at both ends, an electromotive force related to temperature will be generated in the loop, thereby determining the temperature of the measured medium. This handheld design allows users to easily measure temperature at different locations, providing strong support for temperature monitoring and control.

[0003] However, existing handheld metal conductor dynamic temperature meters mainly rely on thermocouples for temperature measurement, which has certain limitations. On the one hand, the accuracy of thermocouples is usually not as good as that of resistance temperature detectors (RTDs) or thermistors, and the measurement accuracy is generally within 1°C to 2°C, which is difficult to meet the needs of high-precision temperature measurement. On the other hand, thermocouples require cold-end compensation to ensure that the temperature of the hot end is measured rather than the temperature of the cold end, which increases the complexity and maintenance cost of the equipment.

The interior of the housing 11 is divided into two parts, an upper part and an lower part, 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.

[0022] In this embodiment, the main body of the housing 11 device provides structural support and protection. The large wheel 12 is installed at the top center of the housing 11, and is used to cooperate with the two small wheels 13 to clamp the metal conductor (cable core), and at the same time serves as the hot end of the thermocouple temperature measurement. The two small wheels 13 are symmetrically arranged on both sides of the large wheel 12, and each small wheel 13 corresponds to a rotating arm 14. The power member 15 controls the two rotating arms 14 to rotate simultaneously to adjust the spacing between the small wheel 13 and the large wheel 12. Clamping the metal conductor: The power member 15 controls the two rotating arms 14 to open or close the spacing between the small wheel 13 and the large wheel 12 to achieve clamping and release of the metal conductor.

[0023] The control component 21 is located inside the housing 11 and is electrically connected to the large wheel 12. The touch screen 22 is arranged on one side of the housing 11 and is electrically connected to the control component 21 for operation control and display of measurement results.

[0024] The receiving chamber 31 is arranged on the back of the shell 11, and is used to accommodate the infrared temperature measuring component 3. The flap 32 is arranged on the receiving chamber 31, and can be folded outward to open. The infrared sensor 34 is plugged into the external socket 33, and is used to be electrically connected to the control component 21 for infrared temperature measurement. The switching component 35 is arranged in the flap 32, and is used to drive 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.

[0025] Flexible installation is achieved through the external socket 33: Specifically, by setting the external socket 33 on the flap 32, the infrared sensor 34 can be quickly connected and removed. This design allows the user to flexibly choose whether to install the infrared sensor 34 according to actual needs, thereby improving the adaptability and portability of the device.

[0026] 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 component 35 is provided in the flap 32 and is connected to the power component 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.

[0027] Improving 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.

[0028] 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 additional measurement methods to ensure the comprehensiveness and accuracy of the data.

[0029] Improving 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, and the user can intuitively compare and verify the data, thereby improving the credibility and reliability of the measurement.

[0030] The device can flexibly switch between thermocouple temperature measurement and infrared temperature measurement according to actual measurement needs.

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.

[0031] Reference Figure 4-Figure 6 The power member 15 includes a tooth plate 151 located between the two rotating arms 14. The first teeth 152 are arranged on both sides of the tooth plate 151, and mesh with the second teeth 141 arranged on the outer wall of the rotating end of the rotating arm 14. A first telescopic cylinder 153 is arranged on the inner side of the tooth plate 151 to push the tooth plate 151 to move outward. The large wheel 12 is rotatably arranged at the top center of the housing 11. The 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 arranged on both sides of the housing 11, and the rotating arm 14 rotates in the notches 111.

[0032] It should be noted that the tooth plate 151 is located between the two rotating arms 14, and the first teeth 152 are provided on both sides of the tooth plate 151. The tooth plate 151 is meshed with the second teeth 141 provided on the outer wall of the rotating end of the rotating arm 14 through the first teeth 152, so as to realize 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, and the rotating arm 14 rotates in the notches 111. The notches 111 are designed so that the rotating arm 14 can 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, and the small wheels 13 cooperate with the large wheel 12 to clamp the metal conductor (cable core).

[0033] The first telescopic cylinder 153 is arranged inside the tooth plate 151, and includes a cylinder body and a piston rod body located inside the cylinder body. The piston rod body is fixed to the tooth plate 151, and a spring for driving the piston rod body to return is arranged between the piston rod body and the cylinder body. The first telescopic cylinder 153 pulls the tooth plate 151 inward, thereby driving the rotating arm 14 and the small wheel 13 to rotate, shortening the distance between the two small wheels 13 and the large wheel 12.

[0034] 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.

[0035] The process of clamping the metal conductor is as follows: pull any small wheel 13 to move backward away from the large wheel 12, the small wheel 13 is installed on the rotating arm 14, drives the rotating arm 14 to rotate, and 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 meshing with it, so that the tooth plate 151 is driven to move outward, and the tooth plate 151 moves outward to drive the other rotating arm 14 and the small wheel 13 on the other side that are symmetrically set to rotate, and synchronously open the distance between the two small wheels 13 and the large wheel 12, so that it is convenient to wrap the metal conductor around the surface of the large wheel 12 after half a circle. Because the tooth plate 151 moves outward to pull the first telescopic cylinder 153 to extend, 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 to reset, driving the rotating arms 14 and small wheels 13 on both sides to reset, and the two small wheels 13 are both fitted with the large wheel 12 to achieve clamping and fixing of the metal conductor.

[0036] The effects are as follows: (1) Stable clamping: Through the design of the mechanical structure, the metal conductor is firmly clamped to avoid displacement or loosening during the temperature measurement process. (2) Easy operation: By pulling the linkage between the small wheel 13 and the first telescopic cylinder 153, the metal conductor can be quickly clamped and released, thereby improving the operating efficiency. Through the above design, the handheld metal conductor dynamic temperature measuring instrument can achieve stable clamping of the metal conductor and provide reliable mechanical support for subsequent temperature measurement operations.

[0037] Reference Figure 4-Figure 6 The lower end of the flap 32 is rotatably arranged in the receiving chamber 31 through the switching member 35, and is turned downward with the switching member as the axis to open. When the flap 32 is opened, 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-headed telescopic cylinder 351 located inside the flap 32, and friction wheels 352 are arranged at both ends of the double-headed telescopic cylinder 351, and the friction wheels 352 are sleeved on one end of a rotating rod 353, and the other end of the rotating rod 353 is installed on the inner wall of the housing 11 through a bearing. An airway 354 is arranged inside the flap 32, and one end of the airway 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, and the elastic reset plug 355 is squeezed by the infrared sensor 34. The surface of the tooth plate 151 is provided with two symmetrical rows of third teeth 154, and each third tooth 154 is provided with a first gear 155 corresponding thereto. The first gear 155 is rotatably provided in the housing 11 through a rod body 156, and the first gear 155 is fitted with the friction wheel 352. The double-head telescopic cylinder 351 includes a sleeve 3511 and two piston rods 3512 installed at both ends of the sleeve 3511, and a first spring 3513 for pulling the two piston rods 3512 closer to each other is provided between the two piston rods 3512, and the midpoint of the sleeve 3511 is connected to the airway 354, wherein the piston rod 3512 and the friction wheel 352 are provided with a one-way ratchet structure.

[0038] It should be noted that the lower end of the flap 32 is rotatably arranged in the accommodating 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, and 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, so as to measure the temperature of the metal conductor.

[0039] The switching member 35 includes a double-headed telescopic cylinder 351 part and an airway 354 part located inside the flap 32, wherein one end of the airway 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 configured as 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 airway 354 and squeezes the air in the airway 354 to make it enter the double-headed telescopic cylinder 351, pushing the piston rods 3512 at both ends of the double-headed telescopic cylinder 351 to expand.

[0040] The double-head telescopic cylinder 351 includes a sleeve 3511 and two piston rods 3512 installed at both ends of the sleeve 3511. A first spring 3513 is provided between the two piston rods 3512 for pulling the two piston rods 3512 closer to each other. The midpoint of the sleeve 3511 is connected to the airway 354. One end of each piston rod 3512 is connected to a friction wheel 352 through a one-way ratchet structure. At the same time, the friction wheel 352 can only drive the piston rod 3512 to rotate in one direction, so that the flap 32 can only be flipped open. At the same time, the piston rod 3512 and the flap 32 are matched with a keyway. Such a setting allows the piston rod 3512 to telescopically move in the flap 32. When the piston rod 3512 moves outward, it drives the friction wheel 352 to mesh with the first gear 155, and then reverses under the drive of the first gear 155, so as to drive the flap 32 to reverse and open.

[0041] 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 provided in the housing 11 through a rod body 156. When the first gear 155 is in contact with the friction wheel 352, the flap 32 is driven to rotate and open.

[0042] 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 an axis to flip the upper end downward, keeping the flap 32 horizontal, exposing the external socket 33 on the flap 32, and plugging 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.

[0043] 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. When the small wheel 13 is then pulled to move away from the large wheel 12 for clamping, the toothed 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 fitted thereto to reverse, and drives the flap 32 matched 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.

[0044] Since the friction wheel 352 and the piston rod 3512 are connected by a one-way ratchet gear, the flap 32 will not be reset when the small wheel 13 is released and 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 why the flap 32 is opened unilaterally is to prevent the staff from 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 whole equipment is irregular and inconvenient to store, so they can definitely find it and close it.

[0045] 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, without complicated settings and adjustments.

[0046] The external socket 33 is configured as a USB interface or a TC interface, etc. The external socket 33 is electrically connected to the control component 21 through a cable.

[0047] 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, and 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., so as to expand the functions and application scope of the device.

[0048] Reference Figure 1-Figure 6 , working process and effect description of handheld metal conductor dynamic temperature meter.

[0049] Clamping the metal conductor: Pull any small wheel 13 to move 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 meshing with it, so that the tooth plate 151 is driven 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 that are symmetrically set to rotate, and the distance between the two small wheels 13 and the large wheel 12 is opened synchronously, so that the metal conductor is conveniently wound around the surface of the large wheel 12 after half a circle. Because the tooth plate 151 moves outward, the first telescopic cylinder 153 is stretched, thereby releasing the control of the small wheel 13, and the first telescopic cylinder 153 is shortened and reset 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, and the two small wheels 13 are both fitted with the large wheel 12 to achieve 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.

[0050] When measuring temperature with thermocouples: 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 kept 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.

[0051] When using infrared temperature measurement synchronously: first clamp the metal conductor, and still pull the two small wheels 13 away from the large wheel 12. When the tooth plate 151 moves outward, the third tooth 154 set on the surface of the tooth plate 151 also moves outward, driving the first gear 155 meshing with it to rotate. This is the first gear 155 and the friction wheel 352 fitting and rubbing. The friction wheel 352 reverses, driving the piston rod 3512 to rotate. The keyway limit setting between the piston rod 3512 and the flap 32 drives the flap 32 to rotate on the rotating rod 353, and the flap 32 is flipped outward to open to a horizontal state. The infrared sensor 34 is aimed at the metal conductor for temperature measurement. When the temperature measurement is completed, the flap 32 is manually folded upward, and the infrared sensor 34 is stored in the receiving cavity 31.

[0052] Finally, it should be pointed out that the methods and devices described in detail above are only embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
