Description

Technical Field

[0001] This application relates to temperature measuring devices, and more particularly to a temperature detection structure based on the outer wall of the device. Background Technology

[0002] Some specialized equipment requires temperature measurement of its outer wall during operation. Currently, this measurement often involves temporarily fixing or bundling temperature sensing elements to the outer wall of the equipment for direct contact. However, during long-term operation, vibrations are inevitable, making it difficult to maintain stable contact between the temperature sensing element and the outer wall. Once the contact becomes loose, the temperature measurement data will be inaccurate, failing to accurately reflect the true temperature of the equipment. Furthermore, the temperature sensing element is susceptible to the influence of the external ambient temperature, thus interfering with the accurate assessment of the equipment's operating status.

[0003] To reduce the probability of temperature sensing elements becoming loose, existing technologies involve welding the temperature sensing element to a bracket, which is then installed on the outer wall of the equipment to obtain temperature data. However, when the temperature sensing element fails, it cannot be replaced individually; it must be replaced as a whole with the bracket, which increases costs to some extent. Utility Model Content

Furthermore, reference numerals may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments discussed.

[0055] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0056] This utility model embodiment provides a temperature detection structure based on the outer wall of the device. Please refer to [reference needed]. Figures 1-4 The temperature detection structure based on the outer wall of the device includes a temperature sensing element, a spring, a locking element, and a mounting block.

[0057] Specifically,

[0058] A temperature sensing element, used to sense changes in the temperature of the outer wall of the equipment and convert them into an electrical signal, includes a temperature sensing tube 10 and a heating wire 11. One end of the temperature sensing tube has a groove with an internal thread, and the other end contacts the outer wall 7 of the equipment to sense its temperature. One end of the heating wire is located in the groove and connected to the temperature sensing tube 10; a detachable terminal is installed at the end of the heating wire. The heating wire 11 can be connected to a display instrument or control system via the detachable terminal.

[0059] The spring component includes a first mounting post 20, a second mounting post 21, and a first spring 22, with the first spring 22 mounted between the first mounting post 20 and the second mounting post 21.

[0060] The first mounting post 20 has one end threaded into the insertion slot of the temperature measuring tube 10, and the other end has a first mounting slot 200. The second mounting post 21 has a second mounting slot at one end. The first mounting post 20 and the second mounting post 21 each have a first channel 201 and a second channel passing through them along their respective center lines. The center line of the first spring is aligned with the center lines of both channels, and both ends of the first spring are respectively located in the first mounting slot 200 and the second mounting slot.

[0061] When the detachable terminal is removed from the end of the heating wire, the heating wire 11 can pass through the first mounting post 20, the first spring 22, and the second mounting post 21 in sequence, and the end of the heating wire is exposed on the second mounting post 21. By rotating the first mounting post 20, one end of it is threaded into the insertion slot of the temperature measuring tube 10, which greatly increases the convenience of disassembly and assembly.

[0062] In addition, the side wall of the second mounting post is provided with a plurality of positioning grooves 211 along its circumference. The extension direction of the positioning grooves 211 is the same as the extension direction of the second mounting post 21. The side wall of the second mounting post is also provided with a plurality of limiting grooves 210 along its circumference.

[0063] The locking component, sleeved on the outer wall of the second mounting post, consists of an external threaded post 31, a limiting post 30, and a locking pin 32. The inner wall of the limiting post has a positioning protrusion 301 that matches the positioning groove 211, and the limiting post 30 has a threaded hole 300 that matches the limiting groove 210. The positioning protrusion 301 on the inner wall of the limiting post is inserted into the corresponding positioning groove 211, assisting in aligning the limiting groove 210 with the threaded hole 300. The locking pin 32 is screwed into the threaded hole 300 into the limiting groove 210, and then tightened with a nut, thus completing the assembly of the locking component at the spring component.

[0064] Mounting block 6 is fitted onto the outer wall 7 of the equipment, ensuring it conforms to the outer wall. Specifically, mounting block 6 can be slotted to fit the outer wall 7, and then fixed to it using bolts or welding. Mounting block 6 has a cavity to allow the temperature sensing tube 10 to extend into it. On the side of mounting block 6 facing away from the outer wall 7, there is a first threaded groove for a matching external threaded post 31, allowing the second mounting post 21 to be threadedly connected to the mounting block 6. When the temperature sensing tube 10 is inserted into the mounting block, the first spring partially protrudes from the block. Moving the locking member towards mounting block 6 compresses the first spring 22, causing the second mounting post 21 to rotate and thread the external threaded post 31 into the mounting block. The threaded connection between the locking member and mounting block 6 compresses the first spring 22, forcing the temperature sensing element to press against the outer wall, thus improving the accuracy of the outer wall temperature measurement.

[0065] Based on the above embodiments, the working principle of this application is as follows:

[0066] (1) Assembly on the outer wall 7 of the equipment: First, install the mounting block 6 on the outer wall 7 of the equipment, then insert the temperature measuring element into the mounting block 6, and move the locking part towards the mounting block to drive the second mounting column 21 to compress the first spring 22. Rotate the second mounting column 21 so that it is threaded into the mounting block 6, thereby pressing the temperature measuring element into the mounting block 6.

[0067] (2) When encountering a situation where it is necessary to replace some of the components (such as the failure of the first spring 22): remove the detachable terminal, rotate the locking part to separate it from the mounting block 6, and then remove the second mounting post 21 equipped with the locking part and the first spring 22 from the heat wire 11 in sequence so that the new first spring can be put into the heat wire 11. Then reassemble the second mounting post 21 and the detachable terminal in sequence to complete the replacement of the first spring 22.

[0068] Based on the above embodiments, the advantages of this application are:

[0069] (2) During the temperature measurement process, the temperature measuring element is pressed into the mounting block 6 by the compression of the first spring 22 and the threaded connection between the second mounting post 21 and the temperature measuring element, so that it can fit better with the outer wall 7 of the equipment, thereby improving the accuracy of temperature measurement; the isolation of the mounting block 6 from the external ambient temperature avoids the interference of the environment on the temperature measurement, effectively solving the problem of non-standard installation method of temperature measurement on the outer wall 7 of the equipment.

[0070] (2) The locking device is detachably installed on the outer wall of the mounting block 6, and the end of the heat wire is equipped with a detachable terminal, which makes it easy for the temperature detection structure to be disassembled and removed from the heat wire, so as to facilitate the replacement of components such as the temperature measuring element and the first spring 22, and increases the flexibility of the temperature detection structure.

[0071] Example 2

[0072] Based on Embodiment 1, the detachable terminal of this application includes a plug 40, an inner cylinder, and an outer cylinder 46. Please refer to... Figures 5-8 .

[0073] The plug 40 has a second threaded groove on one side, and an electrode 45 is installed at the bottom of the second threaded groove. The other side of the plug 40 is connected to a display instrument or control system.

[0074] The inner cylinder has three identical slots 440 evenly distributed around its circumference to divide it into three equal parts, thereby allowing the inner cylinder to deform. The inner cylinder is composed of a first cylindrical part 44 and a second cylindrical part 43. The diameter of the first cylindrical part 44 is larger than the diameter of the second cylindrical part 43, and one end of the second cylindrical part is fixed to the bottom of the second threaded groove.

[0075] The outer cylinder 46 is sleeved outside the second cylinder 43 and threaded into the second threaded groove. One end of the outer cylinder 46 is connected to one end of the second spring 42, and the other end of the second spring is connected to the movable sleeve 41.

[0076] When the outer cylinder 46 is threaded to the plug 40, the movable sleeve 41 is moved to compress the second spring 42, so that the first cylinder 44 is exposed in the outer cylinder 46. At this time, the end of the heat wire is inserted into the inner cylinder to abut the electrode 45. The second spring 42 is released, and the outer cylinder 46, which is sleeved on the outside of the inner cylinder, will exert a squeezing force on the first cylinder 44, thereby squeezing the heat wire 11 to fix its position in the inner cylinder.
