Description

[0002] With the emergence of numerous high-rise buildings and large factory workshops, traditional cables, as power transmission conductors, can no longer meet the requirements of high-current transmission systems.

[0043] With the emergence of numerous high-rise buildings and large factory workshops, traditional cables, as power transmission conductors, can no longer meet the requirements of high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and construction. Busbar trunking, on the other hand, is a highly efficient power distribution device for transmitting current, especially suitable for the increasingly tall buildings and large-scale factories that require economical and rational wiring. The busbar trunking connection structure, as an indispensable component in the installation, plays a crucial role. The combination of busbar trunking sections is generally achieved through the insertion of connectors.

[0044] In the current technology, the use of busbar trunking is increasing. As the service life of buildings and power supply equipment increases, it is inevitable that faults will occur at the connection points of the busbar trunking, especially at the connection ports. However, the existing busbars are all encased in the busbar trunking with an integrated molding structure, which means that when the busbar trunking is repaired, the entire busbar usually needs to be de-energized, which is slow and results in a long power outage time, affecting residents' lives.

[0045] Meanwhile, traditional busbar connections are mostly fixed with screws, and replacing busbar connectors requires at least two people to work together. In addition, manual operation has technical problems such as non-standard operation and inability to guarantee the quality of operation.

[0046] To improve repair efficiency and ensure standardized operation, one embodiment of the present invention provides an automatically detachable busbar trunking connection structure. For details, please refer to [link to specific details]. Figures 1-4 , Figure 1 The diagram shows an automatically detachable busbar trunking connection structure according to one embodiment of the present invention. Figure 2 The diagram shown is a structural diagram of a busbar connection mechanism according to one embodiment of the present invention. Figure 3 The diagram shown is a structural diagram of the limiting part in one embodiment of the present invention. Figure 4 The diagram shown is a schematic representation of a flexible, separable housing according to one embodiment of the present invention.

[0047] The automatically detachable busbar trunking connection structure includes: a back plate 1, a first flexible detachable housing 2, a second flexible detachable housing 3, a drive assembly 5, and a busbar connection mechanism 4;

[0048] Both the first flexible detachable housing 2 and the second flexible detachable housing 3 are fixed on the back plate 1, and both the first flexible detachable housing 2 and the second flexible detachable housing 3 are provided with busbar channels 8 that are aligned with each other and are used for external busbars to pass through.

[0049] Both the first flexible separable housing 2 and the second flexible separable housing 3 are equipped with busbar positioning components;

[0050] The busbar connection mechanism 4 is used to abut against the back plate 1 under the control of the drive assembly 5, and the busbar connection mechanism 4 includes an electrically controlled tensioning assembly 46 sleeved on the stud 47 and several sets of pressing parts.

[0051] The electrically controlled tensioning component 46 is controlled by the drive component 5; each of the pressing parts includes a first insulating plate 41, a first conductive plate 42, a second conductive plate 44 and a second insulating plate 45 stacked together. The first insulating plate 41 and the first conductive plate 42 are provided with a first elastic element (not shown in the figure), and the second conductive plate 44 and the second insulating plate 45 are provided with a second elastic element (not shown in the figure). An accommodating space 43 for placing the busbar end is formed between the first conductive plate 42 and the second conductive plate 44.

[0052] Specifically, the backplate 1 serves as a support structure for other components, fixing the position of other mechanisms or components and providing an installation base for other mechanisms.

[0053] The first flexible split housing 2 and the second flexible split housing 3 serve as the outer shells constituting the busbar channel. Their flexible materials facilitate adjustment, while the split design makes installation and maintenance in case of failure convenient. When the drive component is triggered, the two housings can separate along the back plate, expanding the channel space to release the busbar and achieving rapid disassembly.

[0054] Specifically, flexible materials are used to facilitate angle adjustment during installation or elastic deformation during disassembly, thereby reducing mechanical stress on the busbar.

[0055] like Figure 2 As shown, specifically, the busbar connection mechanism also includes a stud 47, an electrically controlled tensioning assembly 46, several sets of pressing parts, and a buffer spring (not labeled in the figure) sleeved on the stud.

[0056] Preferably, there are four sets of extrusion sections, corresponding to four phase line channels.

[0057] Specifically, in the extrusion section, the insulating plate is used to isolate the conductive parts, the conductive plate is used to conduct current, and the elastic element provides elasticity before connection to ensure that the accommodating space 43 can adapt to the size changes of the busbar before installation and to buffer vibration or impact to avoid loose connection.

[0058] Preferably, both the first elastic element and the second elastic element are springs.

[0059] Preferably, both the first elastic element and the second elastic element are elastic rubber pads.

[0060] Preferably, the elastic element provides adaptive clamping force to compensate for displacement caused by busbar dimensional tolerances or thermal expansion and contraction.

[0061] The electrically controlled tensioning component 46 is fitted onto the nut that is compatible with the stud 47. It is used to receive commands from the drive component 5 and drive the nut to move back and forth on the stud 47, thereby realizing automatic tensioning control of the busbar connection mechanism 4.

[0062] Specifically, the size of the accommodating space 43 can be dynamically adjusted through an electronically controlled tensioning component to accommodate busbars with different cross-sectional areas.

[0063] Preferably, the busbar connection mechanism is further provided with a monitoring component; the monitoring component is provided with a miniature probe, a current transformer and a temperature sensor.

[0064] like Figure 3 As shown, limiting parts 6 are evenly distributed on the outside of the flexible split shell. The limiting parts include a first limiting plate 61 and fasteners. The fasteners include a second limiting plate 62, a movable plate 63 and a connecting rod 64.

[0065] The first limiting plate 61 and the second limiting plate 62 are fixed on the back plate 1; the second limiting plate 62 is connected to the moving plate 63 through the connecting rod 64.

[0066] Preferably, the connecting rod 64 is a screw.

[0067] The connecting rod 64 fixes the busbar body by moving the movable plate 63 and fixing the flexible split shell.

[0068] like Figure 4 As shown, specifically, the flexible, separable housing is further provided with a first insulating partition 7, a second insulating partition, a third insulating partition, a fourth insulating partition, and a fifth insulating partition;

[0069] A first phase wire channel is formed between the first insulating partition and the second insulating partition; a second phase wire channel is formed between the second insulating partition and the third insulating partition; a third phase wire channel is formed between the third insulating partition and the fourth insulating partition; and a fourth phase wire channel is formed between the fourth insulating partition and the fifth insulating partition.

[0070] Of the four phase conductors, three lines represent phases A, B, and C respectively, and the other is the neutral line (if the neutral point on the power supply side of the circuit is grounded, the neutral line is also called the zero line).

[0071] The four phase line channels 65 form a busbar channel 8 through which the external busbars pass.

[0072] Specifically, the first flexible separation shell 2 and the second flexible separation shell 3 are each provided with four phase wire channels 65. The limiting part makes the phase wire channels in the two shells aligned, ensuring that the busbar end accurately enters the accommodating space of the extrusion part.

[0073] Meanwhile, the first flexible split housing 2 and the second flexible split housing 3 are also provided with a busbar positioning component (not shown in the figure); the busbar positioning component can control the length of the busbar entering the phase line channel. Preferably, the positioning function is achieved by positioning lines or positioning buckles made on the first flexible split housing 2 and the second flexible split housing 3.

[0074] After the busbars in the first flexible separation housing 2 and the second flexible separation housing 3 are fixed, the drive component 5 controls the action of the busbar connection mechanism 4 through electrical signals or mechanical transmission, controls the busbar connection mechanism 4, the first flexible separation housing 2 and the second flexible separation housing 3 to adapt and connect, and controls the electric control tensioning component 46 to fix the busbars on the basis of the adapted connection.

[0075] Preferably, the drive assembly 5 includes a power module, a power take-up module terminal block, and a conveyor belt, wherein the external busbar provides power to the power module through the power take-up module terminal block, and the drive assembly controls the movement of the busbar connection mechanism through the conveyor belt.

[0076] When the drive component 5 triggers the release command, the electronically controlled tensioning component 46 releases the pressure, the flexible housing separates and expands the channel, and the busbar is pulled out without resistance.

[0077] In one specific embodiment, the drive component 5 includes a power module, a first drive module, a second drive module, and a control module.

[0078] In this embodiment, the power module normally draws power from the bus connection mechanism 4, and a backup battery power supply is provided for emergency use.

[0079] The drive module 5 consists of a drive motor, a control circuit, and a conveyor belt. The first drive module drives the busbar connection mechanism 4 against the back plate via the conveyor belt. During installation or disassembly, it drives the busbar connection mechanism 4 to move forward and backward. The second drive module controls the up and down spiral of the electrically controlled tensioning component 46, that is, controls the tightening and loosening of the busbar connection mechanism 4.

[0080] Preferably, the busbar connection mechanism 4 has conveyor belt mounting slots on both sides. The conveyor belt mounting slots are used to fix the conveyor belt to the busbar connection mechanism 4, which facilitates the driving of the first drive module.

[0081] In the above embodiment, the control module consists of a button, a control circuit board, and a visualization panel. The button is equipped with an operation lock to prevent accidental operation. The button controls the first drive module and the second drive module through the control circuit board. The visualization panel displays the internal connection status of the bus, such as operating temperature, voltage and current, and the status of the bus when it enters the phase line channel.

[0082] like Figure 5 As shown, Figure 5 The diagram shown is a schematic of the insulating housing in one embodiment of the present invention. The automatically detachable busbar trunking connection structure also includes an insulating housing 9, which is disposed on the back plate 1; the insulating housing 9 covers the busbar connection mechanism 4.

[0083] One embodiment of the present invention provides a busbar trunking connection device, the device comprising a plurality of automatically detachable busbar trunking connection structures as described in any of the preceding claims.

[0084] Specifically, the installation method of this device is as follows:

[0085] First, reset the busbar connection mechanism 4 to ensure it returns to its initial most relaxed state; then place the upper and lower busbar sections into the first flexible separation housing 2 and the second flexible separation housing 3 for fixation, and then fix the insulating housing after fixing the busbars; further adjust the slots on both sides of each conductor in the busbar connection mechanism 4 to align with each busbar.

[0086] Compared with the prior art, the beneficial effects of the embodiments of the present invention are at least one of the following:

[0087] The present invention includes a back plate, a first flexible detachable housing, a second flexible detachable housing, a drive assembly, and a busbar connection mechanism. Both the first and second flexible detachable housings are fixed to the back plate, and both have busbar channels that are aligned with each other and allow external busbars to pass through. The busbar connection mechanism is used to abut against the back plate under the control of the drive assembly, and includes an electrically controlled tensioning assembly sleeved on a stud and several sets of pressing parts. The electrically controlled tensioning assembly is controlled by the drive assembly. Each pressing part includes a first insulating plate, a first conductive plate, a second conductive plate, and a second insulating plate stacked together. The first insulating plate and the first conductive plate are provided with a first elastic element, and the second conductive plate and the second insulating plate are provided with a second elastic element. A space for placing a busbar end is formed between the first conductive plate and the second conductive plate. Compared with the prior art, when the present invention receives the installation command, it controls the busbar connection mechanism, the first flexible separation shell and the second flexible separation shell to adapt and connect. On the basis of the adapted connection, it controls the electrical control tensioning component to fix the busbar. Through this process, the present invention can improve the repair efficiency, ensure the normal life of residents, and also ensure the standardization of busbar installation.

[0088] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
