Description
Technical Field
[0001] This invention belongs to the field of busbar technology, specifically a distributed wireless temperature measurement busbar and its connecting connector. Background Technology
[0002] Busbar trunking, also known as busbar trunking system, is a modular set of equipment used for high-power power transmission and distribution in low-voltage power distribution systems. It mainly consists of copper / aluminum conductors, flame-retardant insulation layers, metal protective shells, connectors, and plug-in accessories. It often replaces multiple parallel cables as the main power distribution line. Structurally, it can be divided into compact type, air-insulated type, and fire-resistant type, with rated currents ranging from 250A to 5000A. It is suitable for three-phase four-wire and five-wire power supply systems, with protection levels reaching IP40-IP65, and is suitable for 50Hz low-voltage power supply scenarios. Compared to traditional cables, it has a larger current carrying capacity, better heat dissipation performance, and lower line voltage drop. Currently, it is widely used in high-rise office buildings, commercial complexes, data centers, large factories, hospitals, and rail transit. Fire-resistant busbar trunking can also ensure continuous power supply to emergency circuits during fires. With its advantages of safety, stability, and convenient operation and maintenance, it has become the mainstream solution for modern high-power power distribution.
[0003] The existing busbar trunking joints require tightening multiple bolts one by one, which is a cumbersome assembly process and has low construction efficiency. The tightening at the joints is inconsistent, and the busbar itself is not equipped with a distributed wireless temperature measurement device, so it is impossible to monitor the temperature at the joint in real time, making it difficult to detect overheating faults in time, which poses a potential safety hazard to power distribution. Summary of the Invention
[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides a distributed wireless temperature measurement busbar trunking and its connecting joint, which effectively solves the problems of cumbersome bolt tightening, uneven joint compression, lack of wireless temperature measurement, inability to monitor temperature rise in real time, and potential power distribution safety hazards in the existing busbar trunking.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a distributed wireless temperature measurement busbar and its connecting connector, comprising a busbar body, a busbar fixed in the middle of the busbar body, with insertion holes at both ends of the busbar, a protective cover connected to the insertion end of the busbar body, and a sealing groove at the receiving end of the busbar body, into which the protective cover can be inserted to form a seal; first openings on both the upper and lower sides of the insertion end of the busbar body, and second openings on both the upper and lower sides of the receiving end of the busbar body; a plug rod on the side of the busbar near the receiving end of the busbar body, with hooks hinged in the first openings by elastic elements; distributed wireless temperature sensors are attached to each conductive contact point of the busbar; a wireless acquisition gateway is fitted to the outside of the busbar body; and the distributed wireless... The line temperature sensor is wirelessly connected to the wireless acquisition gateway for real-time acquisition of connector temperature and uploading for monitoring. A mounting slot is provided on one side of the busbar trunking body at the receiving end. A servo motor is fixed inside the mounting slot. Each of the second openings has a sliding locking block with a slot on its inner side. When the locking hook is inserted into the second opening, it can be locked onto the slot of the locking block by an elastic element. The output end of the servo motor has a transmission component, which is connected to the insertion rod and the two locking blocks. When the servo motor operates, the transmission component drives the two locking blocks to move. The movement of the locking blocks can pull the two busbar trunking bodies together tightly by the locking hook. Simultaneously, the transmission component also drives the insertion rod to insert into the insertion port and socket for limiting, thus quickly achieving docking between the two busbar trunking bodies.
[0006] Preferably, positioning rods are fixed at all four corners of the plug-in end of the busbar trunking body, and positioning holes are provided at all four corners of the receiving end of the busbar trunking body, with the positioning rods and positioning holes being compatible.
[0007] Preferably, the inner wall of the second opening is provided with a limiting groove, and a limiting block is fixed on the side of the two locking blocks that are close to each other. The limiting blocks are slidably installed inside the limiting groove.
[0008] Preferably, the elastic element includes a rotating rod fixedly installed at the inner ends of the two hooks. Both ends of the two rotating rods are hinged to the inside of the first opening through a rotating seat. Both ends of the rotating rods are fitted with torsion springs, and both ends of the torsion springs are fixed to the rotating seat and the hooks, respectively. Each hook has a handle fixed to its upper side.
[0009] Preferably, the transmission assembly includes a rotating shaft fixedly installed at the output end of the servo motor. The outside of the rotating shaft is rotated and positioned by a shaft seat and the inside of the mounting groove. A lead screw is fixed at one end of the rotating shaft. A threaded sleeve is fitted on the outside of the lead screw. A support frame is fixed on the outside of the threaded sleeve. The two ends of the support frame are slidably connected to two locking blocks respectively. A gear is fixed at the end of the lead screw away from the servo motor by a shaft rod. A bushing is rotatably installed on the outside of the shaft rod. The top of the bushing is fixed to the receiving end of the busbar body by a connecting arm. The lower part of the gear meshes with the top of the insert rod.
[0010] Preferably, a movable frame is fixed to the outer end of the insertion rod, and a sliding plate is fixed to the inner side of the movable frame. A second sliding groove is provided at the lower part of the receiving end of the busbar trunking body, and the inner side of the sliding plate is slidably installed inside the second sliding groove. Two guide blocks are fixed to the inner side of the support frame, and two guide grooves are provided on the side of the busbar trunking body near the support frame. The two guide blocks are slidably installed inside the two guide grooves. A slider is fixed to the inner side of the threaded sleeve, and a first sliding groove is provided on the inner wall of the mounting groove. The slider is slidably installed inside the first sliding groove.
[0011] Preferably, the distributed wireless temperature sensor adopts a passive CT power supply structure, with one distributed wireless temperature sensor independently deployed at each three-phase line connection point. The wireless acquisition gateway is connected to the background monitoring host, which has the functions of real-time temperature display, over-temperature graded alarm, and historical temperature data storage and retrieval.
[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] (1) The servo motor is used in conjunction with the integrated transmission component to synchronously drive the card block and the plug rod to complete the automatic locking and docking of the busbar, eliminating the operation steps of manually tightening each bolt one by one, greatly shortening the on-site assembly time. The synchronous feeding of the card block can ensure that the joint clamping force is uniform and consistent, avoiding the contact heat problem caused by insufficient local clamping.
[0014] (2) Distributed wireless temperature sensors are deployed at all conductor connection points of the line, and wireless acquisition gateways are used to realize online acquisition and uploading of joint temperature around the clock. The background can view the temperature rise data of each joint in real time. If the temperature exceeds the standard, multi-level alarms will be automatically triggered. Maintenance personnel can deal with potential contact problems in advance and improve the safety of the power distribution system.
[0015] (3) The positioning rod and positioning hole are set to complete the docking and pre-positioning. Multiple sets of sliding grooves and limit block structures constrain the linear displacement of each moving part. During the docking process, the line row is accurately aligned, the conductive contact surface is tightly fitted, the contact resistance is stable during long-term operation, and abnormal temperature rise is not easy to occur.
[0016] (4) Quick disassembly and assembly are achieved by using torsion springs and hooks. The protective cover and sealing groove form an end sealing structure, which has excellent dustproof and waterproof protection. The entire structure is integrated at the end of the busbar trunking. The structure is compact and suitable for the narrow installation space of vertical shafts and machine rooms. It is convenient for expansion, maintenance and disassembly operations in the later stage. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0029] Example 1, by Figure 1 , Figure 3and Figure 6 The present invention includes a busbar trunking body 1, a cable tray 4 fixed in the middle of the busbar trunking body 1, and insertion holes 5 at both ends of the cable tray 4. A protective cover 6 is installed at the insertion end of the busbar trunking body 1, and a sealing groove 37 is opened at the receiving end of the busbar trunking body 1. The protective cover 6 can be inserted into the sealing groove 37 to form an end sealing protection structure. First openings 8 are opened on the upper and lower sides of the insertion end of the busbar trunking body 1, and second openings 9 are opened on the upper and lower sides of the receiving end of the busbar trunking body 1. An insertion rod 10 is provided on the side of the cable tray 4 near the receiving end of the busbar trunking body 1. The first openings 8 are all hinged with hooks 14 with bends by elastic elements.
[0030] Distributed wireless temperature sensors are attached to all conductive joints of busbar 4. A wireless data acquisition gateway is installed on the outside of the busbar trunking body 1. The distributed wireless temperature sensors communicate with the wireless signal to collect the temperature of each joint in real time and upload it to the monitoring terminal. An installation groove 2 is opened on one side of the receiving end of the busbar trunking body 1. A servo motor 3 is fixed inside the installation groove 2. The second opening 9 is equipped with sliding blocks 33. The inner side of the blocks 33 has a slot 36. The output end of the servo motor 3 is equipped with a transmission component. The transmission component is synchronously connected to the plug rod 10 and the two sets of blocks 33. The support frame 25 and the blocks 33 adopt a sliding connection structure. When the two busbar sections are manually pushed to complete the initial connection, the end of the hook 14 contacts the side wall of the block 33 and is blocked by the block 33. The hook 14 rotates outward under force. After the push is completed, the spring force of the torsion spring 13 rebounds and resets the hook 14 so that the bent part of the hook 14 is aligned with the slot 36. The servo motor 3 starts to run in the forward direction, and the lead screw drives the lead sleeve 20 and the support frame 25 to pull inward. Relying on the sliding allowance reserved between the support frame 25 and the locking block 33, the support frame 25 first moves inward. At this stage, the insertion rod 10 is driven to extend forward into the insertion port 7 and the insertion hole 5 by the meshing of the gear 29 to complete the conductive alignment and insertion. After the support frame 25 has completed the sliding gap stroke, the support frame 25 pulls the locking block 33 inward and moves it in the whole. During the inward movement of the locking block 33, the slot 36 actively engages with the bent part of the hook 14 and continues to pull the hook 14 inward, tightly pulling and locking the insertion end busbar and the receiving end busbar together, realizing the step-by-step action of first conducting conductive insertion and then pulling inward to secure it.
[0031] Positioning rods 16 are fixed at the four corners of the plug-in end of the busbar trunking body 1. Positioning holes 17 are opened at the four corners of the receiving end of the busbar trunking body 1. The outer diameter of the positioning rods 16 matches the inner diameter of the positioning holes 17. When the two busbar trunking sections are assembled, the operator aligns the plug-in end with the receiving end and pushes it forward smoothly. The four positioning rods 16 are simultaneously inserted into the corresponding positioning holes 17, which restricts the two busbar trunking sections from shifting up and down or left and right. This enables the two side line bars 4 to be quickly and coaxially aligned without the need for repeated manual correction and ensures complete contact of the conductive contact surfaces.
[0032] The inner wall of the second opening 9 is provided with limiting grooves 35. The two sets of locking blocks 33 are close to each other and the outer wall of one side is fixed with limiting blocks 34. The limiting blocks 34 are slidably assembled inside the limiting grooves 35. The limiting grooves 35 form a horizontal limiting constraint on the limiting blocks 34. The locking blocks 33 can only slide in a straight line inward and outward along the second opening 9, and will not flip, shift or jam. This ensures that the inward pulling stroke of the upper and lower sets of locking blocks 33 is completely synchronized. When the locking groove 36 engages with the bent part of the locking hook 14, the force is uniform and there is no eccentric load.
[0033] Depend on Figure 2 and Figure 5 The elastic element includes a rotating rod 12, which is fixedly installed at the inner end of the hook 14. Both ends of the rotating rod 12 are hinged to the inside of the first opening 8 via a rotating seat 11. Torsion springs 13 are sleeved on the outer walls of both ends of the rotating rod 12. The two ends of the torsion springs 13 are fixedly connected to the rotating seat 11 and the hook 14, respectively. A handle 15 is fixedly extended outward from the upper side of the hook 14. When the plug-in end busbar is manually pushed into the receiving end, the end of the hook 14 first abuts against the outer wall of the locking block 33. The locking block 33 forms a rigid block, forcing the hook 14 to rotate outward around the rotating rod 12. The torsion springs 13 are simultaneously compressed. Yes, then the continuous pushing causes the hook 14 to rebound due to the elastic force of the torsion spring 13. At this time, the hook 14 is aligned with the slot 36, but the slot 36 does not cover the bent part of the hook 14. Subsequently, the locking block 33 pulls inward, and the slot 36 locks the bent part of the hook 14, forming a double lock to prevent the hook from disengaging during the tightening process. When the busbar is disassembled for equipment maintenance, the servo motor 3 drives the locking block 33 to reset outward, and the slot 36 disengages from the bent part of the hook 14. The handle 15 is then manually pulled upward to overcome the elastic force of the torsion spring 13 and lift the hook 14, allowing the two busbar sections to be directly separated.
[0034] Depend on Figure 4 , Figure 6 , Figure 7 and Figure 8The transmission assembly includes a rotating shaft 18, which is fixedly mounted on the output end of the servo motor 3. The shaft 18 is externally positioned within the mounting groove 2 by a shaft seat 19. A lead screw is coaxially fixed at one end of the shaft 18, and a threaded sleeve 20 is threaded onto the outside of the lead screw. A support frame 25 is fixed to the outside of the threaded sleeve 20, and both ends of the support frame 25 are slidably connected to two sets of locking blocks 33. A gear 29 is fixed to the end of the lead screw away from the servo motor 3 via a shaft 26. A bushing 27 is rotatably mounted on the outside of the shaft 26, and the top of the bushing 27 is fixed to the receiving end of the busbar body 1 via a connecting arm 28. The lower tooth surface of the gear 29 meshes with the top teeth of the insert rod 10. When the servo motor 3 is powered on in the forward direction, the rotating shaft 18 drives the lead screw to rotate synchronously, and the threaded pair of the lead screw drives the threaded sleeve 20 and the support frame. 25 moves horizontally inward toward the center of the busbar trough; a sliding gap is reserved between the support frame 25 and the locking block 33. When the support frame 25 initially slides inward, it only moves itself and does not drive the locking block 33 to move synchronously. The gear 29 at the end of the lead screw rotates synchronously with the lead screw and continuously meshes to push the insertion rod 10 forward horizontally. The insertion rod 10 is completely inserted into the insertion port 7 and the insertion hole 5, and the two side busbars 4 complete the conductive connection. After the support frame 25 slides inward to the limit position of the sliding gap, the inner wall of the support frame 25 abuts against the outer wall of the locking block 33 and pulls the locking block 33 inward to move in a horizontal position. During the inward movement of the locking block 33, the slot 36 gradually wraps around the bent part of the hook 14 and continuously pulls the hook 14 inward to tighten the entire busbar at the insertion end towards the receiving end, and the conductive contact surface is completely pressed together.
[0035] A movable frame 30 is fixed to the outer end of the insertion rod 10, and a sliding plate 31 is fixed to the inner side of the movable frame 30. A second sliding groove 32 is opened at the lower part of the receiving end of the busbar trunking body 1. The sliding plate 31 is slidably installed inside the second sliding groove 32. The sliding plate 31 and the second sliding groove 32 cooperate to constrain the insertion rod 10 to only feed horizontally and linearly, preventing the insertion rod 10 from shaking or shifting up and down, and ensuring that the insertion rod 10 is accurately aligned with the insertion hole 5 to complete the insertion. Two guide blocks 21 are fixed to the inner side of the support frame 25, and two guide grooves are opened on the side of the busbar trunking body 1 near the support frame 25. 22. Two guide blocks 21 are slidably assembled inside the guide groove 22. When the support frame 25 slides inward, the guide blocks 21 move synchronously along the guide groove 22 to share the tension borne by the support frame 25 and prevent the support frame 25 from tilting and deforming on one side. The inner side of the threaded sleeve 20 fixes the slider 23. The inner wall of the mounting groove 2 is opened with a first sliding groove 24. The slider 23 is slidably installed inside the first sliding groove 24. The first sliding groove 24 restricts the slider 23 from rotating in the circumferential direction. When the screw rotates, the threaded sleeve 20 only moves in a straight line inward. The whole transmission is without jamming or deflection.
[0036] The distributed wireless temperature sensor adopts a passive CT induction power-gathering structure. Each of the four joints of the three-phase busbar is independently equipped with a distributed wireless temperature sensor. The wireless acquisition gateway is connected to the background monitoring host, which has the functions of real-time temperature display, multi-level over-temperature alarm, historical temperature data storage and report retrieval. After the busbar is powered on and under load, the sensor autonomously senses and draws power from the alternating current of the busbar, without the need to replace the battery. It continuously collects the real-time temperature of the four joints of the busbar and transmits it wirelessly to the nearest wireless acquisition gateway. The gateway summarizes the data of all points and uploads it to the monitoring host. Maintenance personnel can view the temperature curve of each joint in real time. The system has preset multiple temperature thresholds. When the temperature exceeds the limit, it will trigger local audible and visual alarms and remote push notifications to mobile phones to deal with potential overheating due to poor contact in advance.
