Description

Technical Field

[0001] This utility model relates to the field of testing and calibration of temperature measurement equipment, and in particular to an adjustment mechanism and a temperature sensing rod testing device. Background Technology

[0002] Temperature sensing rods, as a key temperature measurement element, are widely used in various fields such as power generation, fire protection systems, industrial automation, environmental monitoring, and medical equipment. Their main function is to respond to changes in ambient temperature through the sensing element and convert the temperature signal into an electrical signal, thereby enabling real-time temperature monitoring and control.

[0003] However, with the rapid development of modern industry and technology, the demand for performance testing and maintenance of temperature sensing rods is increasing, and existing technologies are clearly insufficient to meet these needs. Traditional temperature sensing rod testing methods mainly rely on large, fixed testing equipment. These devices are usually bulky and complex in structure, requiring use in specialized laboratories or testing workshops, making them unsuitable for on-site testing and maintenance. For example, in power systems, temperature sensing rods are often installed in critical locations such as high-voltage equipment, transformers, or cable joints to monitor the operating temperature of the equipment. When performance testing of these temperature sensing rods is required, traditional testing equipment often cannot directly reach the installation location, especially in confined spaces or at heights, making the testing process extremely inconvenient.

[0010] In a preferred embodiment of the adjustment mechanism of this utility model: the support rod and the rod head are hollow tubes; and a set of second limiting circular holes are symmetrically arranged at the end of the support rod away from the rod head.

[0011] In a preferred embodiment of the adjustment mechanism of this utility model: a central shaft is provided on the end cover.

[0012] In a preferred embodiment of the adjustment mechanism of this utility model: when the telescopic component is fully retracted, the second support sleeve, the third support sleeve and the fourth support sleeve are completely housed inside the first support sleeve.

[0013] In a preferred embodiment of the adjustment mechanism of this utility model: the first limiting hole and the second limiting hole are both adapted to the limiting protrusion.

Furthermore, through structural optimization, it minimizes the volume in the retracted state, thereby greatly saving storage space and improving portability.

[0024] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0025] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0026] Reference Figures 1-4 This embodiment provides an adjustment mechanism, including an adjustable length telescopic component 1, including a pipe fitting 11 and a limiting member 12 for fixing the pipe fitting 11; and an adjustable direction rotation component 2, including a support rod 21 rotatably connected to the top of the pipe fitting 11, a rod head 22 fixedly connected to the support rod 21, and an end cap 23 provided at one end of the rod head 22.

[0027] As an optional embodiment, the tube assembly 11 includes a first support sleeve 111, a second support sleeve 112 sleeved inside the first support sleeve 111, a third support sleeve 113 sleeved inside the second support sleeve 112, and a fourth support sleeve 114 sleeved inside the third support sleeve 113.

[0028] As an optional embodiment, the limiting member 12 includes a plurality of limiting pieces 121 that are respectively engaged and connected to the second support sleeve 112, the third support sleeve 113 and the fourth support sleeve 114, and limiting protrusions 122 integrally formed with the limiting pieces 121.

[0029] The limiting piece 121 and the limiting protrusion 122 are made by high-speed steel punching, and the material is iron or copper sheet.

[0030] Among them, a set of second support sleeves 112 are limited by two sets of limiting plates 121, a set of third support sleeves 113 are limited by two sets of limiting plates 121, and a set of fourth support sleeves are limited by two sets of limiting plates 121.

[0031] As an optional embodiment, the first support sleeve 111, the second support sleeve 112, the third support sleeve 113 and the fourth support sleeve 114 are hollow circular tubes.

[0032] As an optional embodiment, a set of first limiting circular holes A are symmetrically provided at one end of the second support sleeve 112, the third support sleeve 113 and the fourth support sleeve 114; and an annular constriction O is provided at the other end of the second support sleeve 112, the third support sleeve 113 and the fourth support sleeve 114.

[0033] As an optional embodiment, the support rod 21 and the rod head 22 are hollow tubes; and a set of second limiting circular holes B are symmetrically arranged at the end of the support rod 21 away from the rod head 22.

[0034] As an optional embodiment, the end cap 23 is provided with a central shaft 231.

[0035] As an optional embodiment, when the telescopic component 1 is fully retracted, the second support sleeve 112, the third support sleeve 113 and the fourth support sleeve 114 are completely housed inside the first support sleeve 111.

[0036] As an optional embodiment, both the first limiting hole A and the second limiting hole B are adapted to the limiting protrusion 122.

[0037] Both the telescopic component 1 and the rotating component 2 are made of lightweight, high-strength aluminum alloy, which makes it easy to place the device stably in different usage scenarios and adjust the test position of the temperature sensing rod test device.

[0038] When the device is used to test the temperature of the temperature sensing rod, if it encounters a narrow space or the temperature sensing rod is installed at a high position and a person cannot enter, the second to fourth support rods of the telescopic assembly 1 can be extended one by one. The second support sleeve 112, the third support sleeve 113 and the fourth support sleeve 114 are locked one by one under the action of the limiting plate 121. Then, by rotating the support rod 21, the approximate direction of the rod head 22 to be tested is adjusted, and the part of the support rod 21 stored at one end of the fourth support sleeve 114 is pulled out until the fourth support sleeve 114 is locked under the action of the limiting plate 121.

[0039] In summary, this utility model achieves length adjustment of the temperature sensing rod testing device through the telescopic component and direction adjustment of the temperature sensing rod testing device through the rotating component; secondly, the telescopic component is compact after retraction, making it easier to store and carry.

[0040] Reference Figures 5-7 This embodiment provides a temperature sensing rod testing device, including a temperature control component 3, which includes a heating resistance wire 31 wound on a central shaft 231, a fan 32 mounted on the central shaft 231, and a temperature sensor 33 mounted on the heating resistance wire 31; an operation component 4, which includes a display screen 41 and a control panel 42 mounted on the outside of the first support sleeve 111, a temperature controller 43 mounted inside the first support sleeve 111, and a plurality of control lines 43 mounted inside the telescopic component 1 and the rotating component 2; and a power supply component 5, which includes a lithium battery pack 51 mounted at the bottom of the first support sleeve 111 and a charging / discharging port 52 mounted on the outside of the bottom of the first support sleeve 111.

[0041] The heating element is a heating resistance wire 31, which can generate heat quickly and evenly, providing different temperature environments for the temperature sensing rod. In addition, the heating resistance wire 31 is set at the front end of the fan 32, and the fan 32 concentrates the heat to the specific location.

[0042] The temperature sensor 33 uses a high-precision thermistor (thermistors are existing technology and will not be described in detail here) to monitor the temperature of the heating circuit in real time and feed the temperature signal back to the display screen 41 to achieve precise temperature control.

[0043] The temperature controller 43 uses a microcontroller as its core and combines the signal fed back by the temperature sensor 33 to perform precise temperature control on the heating resistance wire 31 through a PID algorithm (the PID algorithm is a publicly available technology and will not be described in detail in this utility model). The temperature control range is from 20°C to 100°C.

[0044] The operator can set the required test temperature through the display screen 41 and automatically adjust the power of the heating element through the temperature controller 43 to stabilize the test environment temperature at the set value.

[0045] The thermostat 43 also has an over-temperature protection function. When the temperature exceeds the set safety threshold, it immediately cuts off the power to the heating element to avoid equipment damage or safety accidents caused by excessive temperature.

[0046] The display screen 41 uses an LCD screen and the control panel 42 uses a button-type operation panel. It can not only intuitively display the working status of the test device, the current temperature, the set temperature, the measurement data of the temperature sensing rod and other relevant information, but also make it more convenient for operators to perform various operations, such as turning the device on / off, setting the test temperature, and switching the display interface.

[0047] The control panel 42 also has data storage and query functions, which can record test data of multiple temperature sensing rods, making it convenient for users to view and analyze historical data at any time, and providing a basis for the performance evaluation and quality control of temperature sensing rods.

[0048] The power module 5 uses a rechargeable lithium battery pack 51, which does not require an external power source. It features high capacity and long lifespan, providing a stable power supply for the entire testing device. The lithium battery pack 51 is equipped with an intelligent charging management circuit to prevent overcharging, over-discharging, and short circuits, thus extending battery life.

[0049] The power module 5 also features a power detection function, displaying the remaining battery power in real time on the display screen 41. The device has a charging / discharging port 52, which reminds the user to charge the battery when the power level drops below a set value. Furthermore, the device can directly use an external power source to power the battery while simultaneously charging it.

[0050] When testing the temperature of the temperature-sensing rod, the device first adjusts the telescopic component 1 and the rotating component 2 to bring the heating module 2 close to the required test position. Then, the operator operates the control panel 42, which transmits the heating resistance wire 31 through the control line 44, causing the heating resistance wire 31 to conduct electricity and generate heat. The heat generated by the heating resistance wire 31 is then transferred out by the fan 32. At the same time, the temperature sensor 333 monitors the temperature of the heating resistance wire 31 in real time and feeds it back to the LCD screen through the control line 44 to achieve precise temperature control and thus accurately heat the temperature-sensing rod.

[0051] In summary, this invention effectively achieves heat transfer from the temperature-sensing rod by setting a temperature control component; it achieves temperature control and adjustment of the temperature-sensing rod through an operation component; and finally, this invention effectively ensures stable operation of the device by setting a power supply component.

[0052] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
