Description

Technical Field

[0001] This utility model relates to the field of temperature measurement technology, and more specifically, to an infrared temperature measurement device for the inside of a busbar trunking. Background Technology

[0002] Busbar temperature monitoring devices are used to monitor the operating temperature of busbar trunking in real time. Since operating electrical equipment typically operates under high voltage and high current conditions, certain defects in the equipment can lead to abnormal temperature increases in equipment components. This is especially true at joints, where increased contact resistance and excessively high temperatures can cause combustion, explosion, or even damage or quality issues to the busbar trunking. Therefore, real-time monitoring of the temperature at busbar trunking joints to ensure timely and accurate temperature measurements is crucial.

[0003] In the prior art, Chinese utility model patent CN221055892U discloses an infrared temperature measuring device for the inside of a busbar trunking. In this prior art, the cover plate of the busbar trunking temperature measuring device is usually fixed with bolts. However, in actual use, when maintenance or replacement of the internal infrared temperature measuring mechanism is required, maintenance personnel must use tools to unscrew the bolts to open the cover plate. After maintenance, the bolts must be tightened again. This not only increases the time and labor costs of maintenance work, but also, in scenarios with frequent maintenance, the repeated tightening of the bolts can easily lead to thread wear. The reliability of the connection is affected, and the disassembled bolts and cover plates are independent small parts that are easily lost or dropped in dim or complex environments. In addition, in the existing technology, the cover plate needs to be pressed down continuously during the fixing process under the action of the spring, and the pressing of the cover plate can only be released after all the bolts are connected. Otherwise, the spring will lift the cover plate. If the cover plate tilts during this process, it will also make bolt assembly inconvenient and may even cause more wear on the bolts. In view of this, we propose an infrared temperature measuring device inside the busbar trunking to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of inconvenient maintenance of the infrared temperature measurement device inside the current busbar trunking.

[0005] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides an infrared temperature measurement device for the interior of a busbar trunking. The device includes a busbar trunking body, an internal support frame, and an infrared temperature measurement mechanism mounted on the upper side of the support frame. Vertical plates are fixedly connected to both sides of the busbar trunking body, and a cover plate is positioned between the two vertical plates, located on the upper side of the busbar trunking body. A cavity is formed inside the cover plate, and two sliding bases are slidably connected within the cavity. Each of the two sliding bases has a sliding groove inside. The sliding groove is slidably connected to a trapezoidal locking block. A first reset spring plate is fixedly connected between the trapezoidal locking block and the inner wall of the sliding groove. The two trapezoidal locking blocks slide through the two side surfaces of the cover plate respectively. The two vertical plates have a locking groove on their adjacent side surfaces. The locking groove and the trapezoidal locking block are adapted to each other. A rotating rod is rotatably connected to the inside of the cavity. A connecting component is provided at one end of the rotating rod inside the cavity. The upper end of the rotating rod rotatably passes through the upper surface of the cover plate. A driving component is provided at one end of the rotating rod outside the cover plate.

[0006] As a preferred technical solution of this application, the upper surface of the bracket is fixedly connected with two baffles, the upper surface of the bracket is provided with two clamping plates, the clamping plates are located between the two baffles, the opposite side surfaces of the two clamping plates are provided with a reset mechanism, and the lower surface of the cover plate is provided with a pressing mechanism adapted to the reset mechanism.

[0007] As a preferred technical solution of this application, the connecting component includes a rotating block, which is located inside the cavity and fixedly sleeved on the outside of the rotating rod. Grooves are provided on both sides of the rotating block, and a pull rod is rotatably connected to the inside of each of the two grooves through a shaft.

[0008] As a preferred technical solution of this application, a connector is fixedly connected to one side surface of each of the two sliding bases, and the end of the pull rod away from the rotating block is rotatably connected through a shaft and a connector.

[0009] As a preferred technical solution of this application, the lower end of the rotating rod rotatably extends through the lower surface of the cover plate, and a torsion spring is fixedly connected to the lower surface of the cover plate. The torsion spring is movably sleeved on the outside of the rotating rod, and the end of the torsion spring away from the cover plate is fixedly connected to the end of the rotating rod.

[0010] As a preferred technical solution of this application, the drive assembly includes a handle, which is disposed outside the rotating rod. Two synchronization grooves are formed on the surface of the rotating rod at one end outside the cover plate, and the handle is slidably sleeved on the outside of the rotating rod through the synchronization grooves.

[0011] As a preferred technical solution of this application, a second return spring is movably sleeved on the outside of the rotating rod, the upper end of the second return spring is fixedly connected to the upper end of the rotating rod, and the lower end of the second return spring is fixedly connected to the handle.

[0012] As a preferred technical solution of this application, the upper surface of the cover plate has two through grooves, and the lower surface of the handle is fixedly connected to two positioning blocks, which are adapted to the through grooves.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In the scheme of this application:

[0015] 1. Through the cooperation between the trapezoidal locking block, the first reset spring plate, and the slot, the cover plate can be automatically locked by simply pressing down when it is installed, without the need for cumbersome bolt tightening operations or any tools. This simplifies the process and significantly shortens maintenance time, making it particularly suitable for occasions that require frequent inspections or quick troubleshooting. Furthermore, by lifting and rotating the handle, the two sliding bases can be pulled simultaneously through the cooperation between the rotating block and the pull rod, causing the trapezoidal locking block to disengage from the slot, thus easily removing the cover plate. This effectively avoids the trouble of loosening multiple bolts in a narrow space and also effectively avoids the risk of bolts being lost or falling off, improving the safety and convenience of operation.

[0016] 2. Through the cooperation of the positioning block, through groove, second return spring and handle, the handle cannot be rotated in the fixed state, effectively preventing the cover plate from loosening due to accidental contact. The torsion spring can automatically drive the rotating rod to reset after the handle is released, preparing for the next locking. The second return spring can then ensure that the handle and positioning block automatically fall back and lock. This dual reset mechanism ensures the stability of the mechanism after each action and improves the reliability of the product. Attached Figure Description

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] Example 1

[0029] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5An infrared temperature measuring device for the inside of a busbar trunking includes a busbar trunking body 1. A support 2 is installed inside the busbar trunking body 1, and an infrared temperature measuring mechanism 3 is installed on the upper side of the support 2. The infrared temperature measuring mechanism 3 can monitor the temperature inside the busbar trunking body 1 in real time and will issue an alarm if the temperature exceeds a threshold. This is existing technology and will not be described in detail. Vertical plates 4 are fixedly connected to both sides of the busbar trunking body 1. A cover plate 5 is installed between the two vertical plates 4, located on the upper side of the busbar trunking body 1. A cavity 6 is formed inside the cover plate 5, and two sliding bases 7 are slidably connected inside the cavity 6. Each part is provided with a sliding groove 8, and a trapezoidal locking block 9 is slidably connected inside the sliding groove 8. A first reset spring plate 11 is fixedly connected between the trapezoidal locking block 9 and the inner wall of the sliding groove 8. The two trapezoidal locking blocks 9 slide through the two side surfaces of the cover plate 5 respectively. The two vertical plates 4 are provided with a locking groove 10 on the side surface that is close to each other. The locking groove 10 and the trapezoidal locking block 9 are adapted to each other. A rotating rod 12 is rotatably connected inside the cavity 6. A connecting component is provided at one end of the rotating rod 12 inside the cavity 6. The upper end of the rotating rod 12 rotatably passes through the upper surface of the cover plate 5. A driving component is provided at one end of the rotating rod 12 outside the cover plate 5.

[0030] With the setting of the first reset spring plate 11, when the cover plate 5 is pressed down, the inclined surface of the trapezoidal block 9 will contact the vertical plate 4. At this time, under the action of the inclined surface, the trapezoidal block 9 will be forced to slide inside the sliding groove 8. At this time, the first reset spring plate 11 will be compressed by force. After the trapezoidal block 9 moves to the outside of the slot 10, under the action of the first reset spring plate 11, the trapezoidal block 9 will be inserted into the inside of the slot 10, thereby fixing the cover plate 5.

[0031] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, two baffles 23 are fixedly connected to the upper surface of the bracket 2, and two clamping plates 24 are provided on the upper surface of the bracket 2. The clamping plates 24 are located between the two baffles 23. The opposite sides of the two clamping plates 24 are provided with reset mechanisms 25. The lower surface of the cover plate 5 is provided with a pressing mechanism 26 that is compatible with the reset mechanism 25. Through the cooperation between the reset mechanism 25 and the pressing mechanism 26, when the cover plate 5 is pressed down, it will drive the two clamping plates 24 to move towards the middle, thereby achieving the clamping of the infrared temperature measuring mechanism 3.

[0032] The reset mechanism 25 and the pressing mechanism 26 are both existing technologies in the field, and have the same structure and principle as the existing technology with announcement number CN221055892U, so they will not be described in detail.

[0033] Example 2

[0034] The infrared temperature measuring device inside the busbar trunking provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the connecting assembly includes a rotating block 13, which is located inside the cavity 6 and fixedly sleeved on the outside of the rotating rod 12. Grooves 14 are provided on both sides of the rotating block 13. A pull rod 15 is rotatably connected to the inside of each of the two grooves 14 through a shaft. The rotation of the rotating rod 12 can drive the rotation of the rotating block 13, and the rotation of the rotating block 13 can drive the movement of the pull rod 15.

[0035] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the two sliding bases 7 are fixedly connected to the adjacent side surfaces of each other with a connector 16. The end of the pull rod 15 away from the rotating block 13 is rotatably connected to the connector 16 through a shaft. When the rotating block 13 drives the pull rod 15 to move, the pull rod 15 will pull the connector 16 to move. The movement of the connector 16 can drive the movement of the sliding base 7, thereby driving the movement of the trapezoidal block 9, so that the trapezoidal block 9 can be disengaged from the inside of the slot 10, so as to facilitate the disassembly of the cover plate 5.

[0036] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the lower end of the rotating rod 12 rotates through the lower surface of the cover plate 5. A torsion spring 17 is fixedly connected to the lower surface of the cover plate 5. The torsion spring 17 is movably sleeved on the outside of the rotating rod 12. The end of the torsion spring 17 away from the cover plate 5 is fixedly connected to the end of the rotating rod 12. When the rotating rod 12 rotates, the torsion spring 17 will undergo corresponding deformation because one end is fixedly connected to the cover plate 5, so that the rotating rod 12 can be reset later.

[0037] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the drive assembly includes a handle 18, which is disposed outside the rotating rod 12. Two synchronization grooves 19 are formed on the surface of the rotating rod 12 located outside the cover plate 5. The handle 18 is slidably sleeved on the outside of the rotating rod 12 through the synchronization grooves 19. With the help of the synchronization grooves 19, the handle 18 can slide outside the rotating rod 12, and the rotating rod 12 can be driven to rotate when the handle 18 rotates.

[0038] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a second return spring 20 is movably sleeved on the outside of the rotating rod 12. The upper end of the second return spring 20 is fixedly connected to the upper end of the rotating rod 12, and the lower end of the second return spring 20 is fixedly connected to the handle 18. By setting the second return spring 20, when the handle 18 is lifted and slides outside the rotating rod 12, the second return spring 20 will generate a corresponding deformation, so that the handle 18 can return to its original position when it is released.

[0039] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, two through slots 21 are opened on the upper surface of the cover plate 5, and two positioning blocks 22 are fixedly connected to the lower surface of the handle 18. The positioning blocks 22 and the through slots 21 are adapted to each other. When the positioning blocks 22 are located inside the through slots 21, the handle 18 cannot rotate, thereby effectively ensuring the stability of the rotating rod 12.

[0040] The usage process of the infrared temperature measuring device inside the busbar trunking provided by this utility model is as follows:

[0041] When it is necessary to fix the cover plate 5 and the busbar trunking body 1, the operator can press down the cover plate 5. When the cover plate 5 is pressed down, the inclined surface of the trapezoidal locking block 9 will contact the vertical plate 4. At this time, under the action of the inclined surface, the trapezoidal locking block 9 will be forced to slide inside the sliding groove 8. At this time, the first reset spring plate 11 will be compressed by force. After the trapezoidal locking block 9 moves to the outside of the slot 10, under the action of the first reset spring plate 11, the trapezoidal locking block 9 will be locked into the inside of the slot 10, thereby fixing the cover plate 5.

[0042] In addition, through the cooperation between the reset mechanism 25 and the pressing mechanism 26, when the cover plate 5 is pressed down, it will drive the two clamping plates 24 to move towards the middle, thereby achieving the clamping of the infrared temperature measuring mechanism 3.

[0043] When it is necessary to remove the cover plate 5, the operator can hold the handle 18 and lift it upwards. At this time, the handle 18 will slide outside the rotating rod 12, and the second return spring 20 will produce elastic deformation. After the positioning block 22 is disengaged from the inside of the through groove 21, the operator can rotate the handle 18 to drive the rotating rod 12 to rotate. At this time, the rotation of the rotating rod 12 will drive the rotation of the rotating block 13. The rotation of the rotating block 13 will drive the movement of the pull rod 15. When the rotating block 13 drives the pull rod 15 to move, the pull rod 15 will pull the connecting piece 16 to move. The movement of the connecting piece 16 will drive the movement of the sliding base 7, thereby driving the movement of the trapezoidal locking block 9, so as to disengage the trapezoidal locking block 9 from the inside of the slot 10, so as to facilitate the removal of the cover plate 5.

[0044] In addition, when the rotating rod 12 rotates, the torsion spring 17 will undergo corresponding deformation because one end is fixedly connected to the cover plate 5, so that the rotating rod 12 can be reset later.
