Description

Technical Field

[0001] This invention relates to the field of temperature sensing and measurement technology, and in particular to a temperature sensing and measurement device with built-in fuse protection. Background Technology

[0002] The temperature measurement device with built-in fuse protection works by using a dual mechanism of temperature monitoring and fuse protection to prevent overheating. The device monitors the device temperature in real time using temperature sensors (such as thermistors, thermocouples, or infrared sensors). When the temperature exceeds a set threshold, the built-in fuse (such as a thermal fuse) will blow, cutting off the circuit. The sensor transmits the temperature data to the receiving unit wirelessly (such as via the 470MHz band) or via wired connection, and then displays and issues warnings in real time through a cloud platform or local system. A typical application is temperature monitoring in high-voltage switchgear, ring main units, and other equipment to prevent overheating caused by contact oxidation and aging. In existing technology, temperature sensors need to be installed on the copper busbars in the cabinet to measure their temperature. The installation process generally involves passing a flexible alloy strip through the locking device, rubber pads, and mounting slots in the sensor body in sequence. Two rubber pads are placed on both sides of the sensor body. After the sensor is attached to the copper busbar, the alloy strip is pressed tightly by the locking device.

[0003] The locking component consists of a frame and a clamping screw inside the frame. After the alloy sheet is clamped by the clamping screw, the tightness of the contact between the sensor body and the copper busbar cannot be guaranteed. That is, the alloy strip used for binding lacks a tensioning component to improve its binding tightness to the sensor body. Furthermore, if the tightness of the contact between the sensor body and the copper busbar is reduced, external impurities may also enter the gap between the sensor body and the copper busbar, which will affect its measurement work.

[0004] To address these issues, this invention proposes a temperature sensing and measurement device with built-in fuse protection. Summary of the Invention

[0005] The purpose of this invention is to provide a temperature sensing and measuring device with built-in fuse protection to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a temperature sensing and measuring device with built-in fuse protection, comprising a temperature sensor body and a mounting slot disposed in the temperature sensor body; The temperature sensor body is mounted on a copper busbar using an alloy strip and a clamping component. Auxiliary components are provided on both sides of the temperature sensor body; The auxiliary component includes a protective housing and a robust structure, the protective housing protecting the contact area between the temperature sensor body and the copper busbar; This robust structure improves the installation stability of the temperature sensor body by tightening the alloy strip.

[0007] Preferably, there are two protective covers, which are joined together to form a protective cover.

[0008] Preferably, the auxiliary component further includes a mounting foot disposed on one side of the protective cover, which is fixedly connected to the side wall of the temperature sensor body by screws.

[0009] Preferably, the protective cover is fixedly mounted at one end of the connecting sleeve; The connecting sleeve has a movable strip, which, together with the connecting sleeve, forms a telescopic adjustment control. This telescopic adjustment control is positioned by a set positioning structure.

[0010] Preferably, the positioning structure includes adjustable slots that are equidistantly arranged in a straight line on one side of the movable strip; The opening of the control slot is circular; A positioning screw is also threaded on one side of the connecting sleeve. The end of the positioning screw is adapted to engage with the regulating slot. The two work together to provide positioning for the moving bar.

[0011] Preferably, one end of the movable strip is connected to the stable structure; The sturdy structure includes support plates that are fixedly connected to the movable strip and are located on both sides of the copper busbar.

[0012] Preferably, support frame strips are symmetrically fixed at both ends on one side of the support plate, and a limiting groove is formed between adjacent support frame strips; A screw groove is provided at the end of the support frame, and a connecting cover plate is fixed at the end of the support frame by screws.

[0013] Preferably, a tensioning stud is provided through a threaded connection in the connecting cover plate; A handle body is fixedly installed at one end of the tensioning stud, and an auxiliary bearing is sleeved at the other end of the tensioning stud. The auxiliary bearing is embedded in the connecting frame strip, and the connecting frame strip is connected to the bearing column.

[0014] Preferably, a locking nut is also threaded onto the tensioning stud; This locking nut is used to improve the stability of the tension stud.

[0015] Preferably, a through groove is formed between the connecting frame and the supporting column; This groove is used for inserting alloy strips; Both ends of the supporting column are located in the limiting groove between the supporting frame bars, and the width of the limiting groove is equal to the diameter of the supporting column.

[0016] Compared with the prior art, the beneficial effects of the present invention are: The temperature sensing and measuring device with built-in fuse protection designed in this invention includes a temperature sensor body and a mounting slot disposed in the temperature sensor body; the temperature sensor body is mounted on a copper busbar through the cooperation of an alloy strip and a clamping component; wherein, in this design, auxiliary components are provided on both sides of the temperature sensor body; the auxiliary components include a protective cover and a stabilizing structure, the protective cover protects the contact position between the temperature sensor body and the copper busbar, and the stabilizing structure improves the installation stability of the temperature sensor body by tightening the alloy strip; This solution for temperature sensor installation and use involves installing the sensor using an alloy strip and clamping components, and then using auxiliary components to tighten the alloy strip, thereby improving the installation stability of the temperature sensor. Specifically, the alloy strip is further tightened through the cooperation of the supporting column, connecting frame, and tensioning stud in the stabilizing structure. After the alloy strip is clamped by the clamping components, the tensioning stud in the stabilizing structure moves the supporting column, thereby tightening the portion of the alloy strip attached to the supporting column. This makes the alloy strip more taut. Specifically, when the alloy strip passes through the stabilizing structure, it passes through the slot between the connecting frame and the supporting column. After the alloy strip is clamped by the clamping components, the tensioning stud is rotated by the handle, and the tensioning stud moves the supporting column to tighten the alloy strip. This further stabilizes the position of the temperature sensor. Based on this, the protective cover set in the auxiliary component provides protection for the contact position between the temperature sensor body and the copper busbar, preventing external impurities from accumulating and adhering at the contact position, and ensuring the measurement operation of the temperature sensor body; that is, the protective cover set on both sides of the temperature sensor body forms a protective cover, which provides a shield for the contact position between the temperature sensor body and the copper busbar to prevent external impurities from adhering and accumulating at the contact position.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figures 1-10 A temperature sensing and measuring device with built-in fuse protection includes a temperature sensor body 2 and a mounting slot 21 disposed in the temperature sensor body 2; the temperature sensor body 2 is mounted on a copper busbar 1 by the cooperation of an alloy strip 3 and a clamping member 4. In this design, auxiliary components are provided on both sides of the temperature sensor body 2. The auxiliary components include a protective cover 601 and a stabilizing structure. The protective cover 601 protects the contact position between the temperature sensor body 2 and the copper busbar 1. The stabilizing structure improves the installation stability of the temperature sensor body 2 by tightening the alloy strip 3.

[0021] According to the appendix Figure 1 - Appendix Figure 6As shown, this solution, for the installation and use of the temperature sensor, firstly, installs it using the alloy strip 3 and the clamping component 4, and then uses an auxiliary component to tighten the alloy strip 3, thereby improving the installation stability of the temperature sensor; that is, the alloy strip 3 is further tightened by the cooperation of the bearing column 801, the connecting frame strip 802 and the tensioning stud 804 in the stabilizing structure, so as to further stabilize the position of the temperature sensor. In addition, the protective cover 601 provided in the auxiliary components provides protection for the contact position between the temperature sensor body 2 and the copper busbar 1, preventing external impurities from accumulating and adhering at the contact position, and ensuring the measurement operation of the temperature sensor body 2.

[0022] Among them, from the appendix Figure 1 - Appendix Figure 4 As shown, for the installation of the temperature sensor body 2, the alloy strip 3 is first passed through the clamping part 4, the stabilizing structure on one side of the temperature sensor body 2, then through the mounting slot 21 in the temperature sensor body 2, then through the stabilizing structure on the other side of the temperature sensor body 2, and finally through the clamping part 4.

[0023] Next, the temperature sensor body 2 is pressed tightly against the copper busbar 1, and the support plates 701 in the stabilizing structure on both sides of the temperature sensor body 2 are in contact. Then, the alloy strip 3 is pulled taut by hand, and then the alloy strip 3 is pressed tightly by the clamping part 4. At this point, the initial installation of the temperature sensor body 2 is completed.

[0024] To further improve the binding effect of the alloy strip 3 on the temperature sensor body 2, it is necessary to further tighten the alloy strip 3 to avoid the problem of the alloy strip 3 becoming loose and affecting the stability of the temperature sensor body 2. In other words, the alloy strip 3 is further tightened by using a stabilizing structure.

[0025] Combined with the appendix Figure 5 - Appendix Figure 8 As shown, the auxiliary components are designed to be detachable, which facilitates future replacement and maintenance.

[0026] For the use of auxiliary components, there are two protective covers 601 in the auxiliary components, and the two protective covers 601 are spliced ​​together to form a protective cover; the auxiliary components also include a mounting foot 602 on one side of the protective cover 601, which is fixedly connected to the side wall of the temperature sensor body 2 by screws.

[0027] In other words, the protective cover 601 is first wrapped around one side of the temperature sensor body 2. The mounting feet 602 on the protective cover 601 are attached to one side of the temperature sensor body 2. Then, the mounting feet 602 are fixed with screws. At this point, the installation of the protective cover 601 on one side of the temperature sensor body 2 is completed. Then, following the same operation method, another protective cover 601 is installed on the other side of the temperature sensor body 2. After the other protective cover 601 is installed, the two protective covers 601 will be spliced ​​together to form a protective cover. This protective cover provides a shield and protection for the contact position between the temperature sensor body 2 and the copper busbar 1, preventing external impurities from accumulating and adhering at the contact position.

[0028] From the appendix Figure 4 As shown, after the protective cover 601 is installed, the connecting sleeve 501 is also installed. The protective cover 601 is fixedly installed at one end of the connecting sleeve 501. A movable strip 502 is movably installed in the connecting sleeve 501. The movable strip 502 and the connecting sleeve 501 cooperate to form a telescopic adjustment control. The telescopic adjustment control is positioned by a positioning structure. The positioning structure includes adjustment slots 503 that are equidistantly arranged in a straight line on one side of the movable strip 502. The opening of the adjustment slots 503 is circular. A positioning screw 504 is also threadedly connected to one side of the connecting sleeve 501. The end of the positioning screw 504 is adapted to engage with the adjustment slots 503. The two work together to position the movable strip 502.

[0029] Combined with the appendix Figure 7 -Appendix Figure 10 As shown, one end of the movable strip 502 is connected to the stable structure.

[0030] In other words, when the temperature sensor body 2 is tightly attached to the copper busbar 1, it is necessary to ensure that the set stabilizing structure is located on the side of the copper busbar 1. In order to better adapt to different copper busbars 1, that is, to improve the flexibility of the stabilizing structure, this solution uses the telescopic structure formed by the connecting sleeve 501 and the movable strip 502 to adjust the stabilizing structure.

[0031] When the temperature sensor body 2 is attached to the side wall of the copper busbar 1, the movable bar 502 needs to be pulled until the support plate 701 in the stabilizing structure contacts the side of the copper busbar 1. Then, by rotating the positioning screw 504 on the connecting sleeve 501, the end of the positioning screw 504 is engaged with the adjustment slot 503 at the corresponding position of the movable bar 502, thus realizing the positioning of the movable bar 502 and the stabilizing structure.

[0032] From the appendix Figure 9 -Appendix Figure 10As shown, the stabilizing structure in this solution includes a support plate 701 that is fixedly connected to the movable strip 502. The support plate 701 is located on both sides of the copper busbar 1. Support frame strips 702 are symmetrically fixed at both ends on one side of the support plate 701, and a limiting groove 703 is formed between adjacent support frame strips 702. A screw groove is provided at the end of the support frame strip 702, and a connecting cover plate 704 is fixedly provided at the end of the support frame strip 702 by screws.

[0033] After the stabilizing structure is installed and positioned, the alloy strip 3 is pressed by the clamping component 4, and then the stabilizing structure is used to further tighten the alloy strip 3.

[0034] A tensioning stud 804 is threaded through the connecting cover plate 704; a handle body 805 is fixedly installed at one end of the tensioning stud 804, and an auxiliary bearing 803 is sleeved at the other end of the tensioning stud 804. The auxiliary bearing 803 is embedded in the connecting frame strip 802, and the connecting frame strip 802 is connected to the bearing column 801; both ends of the bearing column 801 are respectively located in the limiting groove cavities 703 between the supporting frame strips 702, and the width of the limiting groove cavities 703 is equal to the diameter of the bearing column 801.

[0035] Here, a through groove is formed between the connecting frame 802 and the supporting column 801; this through groove is used for the insertion of the alloy strip 3; that is, when the alloy strip 3 passes through the stable structure, the alloy strip 3 passes through the through groove between the connecting frame 802 and the supporting column 801. After the alloy strip 3 is pressed by the clamping member 4, the tensioning stud 804 is rotated by the handle body 805. During this process, an auxiliary bearing 803 is provided at the connection position between the tensioning stud 804 and the connecting frame 802, and the supporting column 801 passes through the limiting groove between the supporting frame 702. The cavity 703 is limited. When the tensioning stud 804 is rotated, the tensioning stud 804 will drive the bearing column 801 to move linearly and towards the connecting cover plate 704 until the tensioning stud 804 is tightened. The tightening of the alloy strip 3 is then completed. During this process, when the alloy strip 3 is further tightened by the stabilizing structure, the alloy strip 3 is initially tightened by hand when it is pressed by the clamping member 4. At this time, the bearing column 801 provides a squeezing effect on the alloy strip 3 attached to it.

[0036] A locking nut 806 is threadedly connected to the tensioning stud 804. The locking nut 806 is used to improve the stability of the tensioning stud 804. That is, after the tensioning stud 804 is tightened by the handle body 805, the locking nut 806 is rotated until it is tightened, which provides a locking and stabilizing effect for the tensioning stud 804.

[0037] The connecting cover plate 704 and the support frame strip 702 on the support plate 701 are fixed with screws to facilitate disassembly, thereby making it easy to remove and replace the bearing column 801.

[0038] Combined with the appendix Figure 1 -Appendix Figure 10 As shown, when it is necessary to disassemble the temperature sensor body 2 in the future, first release the clamping effect of the clamping member 4 on the alloy strip 3, and then pull out the alloy strip 3. That is, pull out the alloy strip 3 in sequence from the clamping member 4, the stabilizing structure and the mounting slot 21 of the temperature sensor body 2, and the fixation of the temperature sensor body 2 can be released.

[0039] Additionally, when it is necessary to remove the protective cover installed on the temperature sensor body 2, that is, to remove the protective cover 601 on both sides of the temperature sensor body 2, simply unscrew the screws that fix the mounting feet 602, and then remove the protective cover 601.

[0040] During this process, the bearing column 801 needs to be reset so that the alloy strip 3 can be tightened next time. Simply rotate the tensioning stud 804 in the opposite direction to reset the bearing column 801.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
