Description

Technical Field

[0001] This utility model belongs to the field of power transmission, and in particular relates to an electric rotating power take-up head device on a plug-in box. Background Technology

[0002] Intelligent sliding contact type miniature busbars are devices in modern power distribution systems that adapt to the flexible power supply requirements. Their core feature is the combination of sliding contact conductivity and rotating docking. They consist of a fixed busbar body (containing conductive rails) and a movable docking component. The docking component can rotate to a specific angle to electrically connect or disconnect with the busbar rails. Furthermore, they integrate intelligent sensing functions such as current and voltage monitoring, providing real-time feedback on power supply status. Power can be partially cut off or removed without overall disassembly, meeting the demands for flexible and intelligent power distribution.

[0003] As data centers scale up and their computing power increases, the requirements for power distribution reliability, flexibility, and spatial adaptability rise, making this type of busbar a core power distribution component. Data center cabinets need to dynamically adjust their power supply unit configurations based on the number of servers deployed and changes in computing load. Intelligent sliding contact mini-busbars (rotary type) can be laid along pre-set paths along cabinet rows or ceiling / floor. The plug-in box, acting as an intermediate unit connecting the busbar to the cabinet load, enables quick plug-and-play power access through rotating docking with the busbar, eliminating the need to modify the overall busbar structure. This significantly shortens the power distribution modification cycle during cabinet expansion and load adjustments, meeting the rapid iteration and maintenance needs of data centers. Data centers are increasingly demanding in terms of space utilization, requiring more cabinets and computing equipment to be accommodated within limited server room space. Compared to traditional cable power supply or fixed busbars, intelligent sliding contact mini-busbars have a more compact structure, can be laid in narrow vertical or horizontal spaces, and reduce cable redundancy through rotating docking.

[0004] Traditional plug-in boxes typically use a manual rotation method for power take-off heads. In data center applications, this requires reserving space for manual operation, which limits the installation spacing of plug-in boxes, restricts the number of boxes that can be installed per unit area, and reduces the utilization rate of data center space. Reliance on manual operation makes it impossible to integrate with automated operation and maintenance systems. Batch adjustments are labor-intensive and inefficient, contradicting the trend towards unattended operation and remote control. Operators must maintain close contact, increasing the risk of electric shock due to improper operation or insulation aging. Furthermore, manual control of force and angle can easily lead to poor contact, causing overheating and arcing. Utility Model Content

[0005] The purpose of this utility model is to provide an electric rotating power take-up head device on a plug-in box, so as to solve the technical problems of traditional plug-in box manual rotating power take-up head in the application of intelligent sliding contact type small busbar in data center, which are dependent on manual operation, low level of automation and intelligence, insufficient safety, and low space utilization due to large space occupation of rotating insertion.

[0006] To achieve the above objectives, the specific technical solution of the electric rotary power take-up head device on the plug-in box of this utility model is as follows:

[0007] An electric rotating power take-off head device on a plug box includes a power take-off structure disposed inside the plug box, and a base rotator for driving the power take-off structure to rotate.

[0008] The power-collecting structure includes a connecting post protruding upward from the upper end face of the plug box, a rotating base machine disposed inside the plug box and connected to the connecting post, and a power-collecting head exposed on the upper end face of the connecting post; the rotating base machine exposes a rotating interface on the surface of the plug box, and the base machine rotator is mounted on the surface of the plug box through the rotating interface;

[0009] The connecting post has a connecting protrusion on its side, which corresponds to the connecting groove in the busbar groove. After the connecting post enters the busbar groove, the power taking head contacts the busbar conductor to take power. The connecting post rotates under the drive of the base machine rotator. After the connecting protrusion rotates, it enters the connecting groove to complete the installation and fixation of the power taking structure in the busbar groove.

[0010] As a further improvement of this utility model, the inner wall of the busbar groove is provided with a connecting block protruding in opposite directions corresponding to the connecting protrusion, and the connecting block is provided with a connecting groove recessed on the opposite side. The connecting column rotates to realize the movement of the connecting protrusion in and out of the connecting groove.

[0011] As a further improvement of this utility model, the rotation angle of the power taking structure is 90 degrees, the connecting protrusion faces the length direction of the busbar groove when the connecting column enters the busbar groove, and the connecting protrusion faces the connecting block after the power taking structure rotates.

[0012] As a further improvement of this utility model, the base machine rotator includes a manual mode and a remote mode. In the manual mode, the base machine rotator is driven to rotate by a handle on its surface, and in the remote mode, the base machine rotator is operated without contact via a built-in wireless communication module.

[0013] As a further improvement of this utility model, the power-taking head is equipped with a current sensor and a temperature sensor, and the base rotator has a built-in signal processing unit and an alarm unit; the signal processing unit preprocesses the current data collected by the current sensor and the temperature data collected by the temperature sensor, and uploads the processed data to the control backend through the wireless communication module; the signal processing unit presets current thresholds and temperature thresholds, and triggers an alarm message through the alarm unit when the actual data exceeds the preset thresholds.

[0014] As a further improvement of this utility model, the alarm unit includes an audible and visual alarm unit disposed on the surface of the plug-in box and a remote alarm unit that sends alarm information to the control backend.

[0015] As a further improvement of this utility model, the end of the connecting protrusion is provided with an arc-shaped guide surface, and the entrance of the connecting groove is provided with an inclined guide surface corresponding to the arc-shaped guide surface; the arc-shaped guide surface and the inclined guide surface cooperate to form a rotating docking guide structure.

[0016] As a further improvement of this utility model, the rotating interface is provided with a limit block, which limits the rotation angle of the base machine rotator.

[0017] As a further improvement of this utility model, the base machine rotator is detachably connected to the rotation interface.

[0018] Beneficial effects:

[0019] The power-taking structure is driven to rotate by a base rotator, replacing the manual rotation of the power-taking head in traditional plug-in boxes. This eliminates the need for maintenance personnel to use hand tools or apply force to operate the power-taking head, avoiding the problem of poor contact between the power-taking head and the busbar conductor caused by uneven force and angle deviation during manual operation, thus ensuring stable current transmission. The automated drive eliminates the efficiency limitations of manual operation, especially when the power-taking status of multiple plug-in boxes needs to be adjusted in batches in data centers. It eliminates the need for manual operation of each box, greatly reducing operation time. This meets the core requirement of modern power distribution systems for automated operation and solves the drawbacks of low efficiency and reliance on manual labor in traditional manual methods.

[0020] The connecting post first enters the busbar trunking to bring the power-taking head into contact with the busbar conductor. Then, through rotation, the connecting protrusion enters the connecting groove for fixation. This logic of insertion followed by rotation completely changes the traditional power-taking method of insertion during rotation. Traditional methods require double redundancy space for both insertion and rotation (e.g., to avoid collision with the busbar trunking during rotation, the distance between the plug-in box and the busbar trunking needs to be increased). In this device, the connecting post does not need to rotate synchronously when inserted into the busbar trunking; it only needs to fit the insertion space of the connecting post itself. The subsequent rotation and fixing action is driven by the base unit rotator, and the rotation process is confined to the power-taking structure itself, without the need to expand the surrounding space. This design allows the installation spacing between adjacent plug-in boxes to only retain the basic heat dissipation gap, significantly increasing the number of plug-in boxes installed per unit of computer room space, perfectly meeting the core requirements of high-density layout and high space utilization in data centers.

[0021] The integrated design of the power-taking structure, including the connecting column, rotating base, and power-taking head, combined with the matching and fixing structure of the connecting protrusion and the connecting groove, forms a double stability guarantee. The fixed connection between the power-taking head and the connecting column ensures that the power-taking head rotates synchronously with the connecting column, avoiding the problems of loosening and displacement of the power-taking head in traditional split structures. After the connecting protrusion enters the connecting groove, it can form a circumferential limit on the power-taking structure, preventing the power-taking head from rotating unexpectedly due to equipment vibration or external force contact. This ensures that the power-taking head and the busbar conductor always maintain stable contact, avoiding faults such as local overheating and arc discharge caused by loose contact. It solves the hidden dangers of poor fixation and easy loosening of traditional manual power taking, and extends the service life of the device and the operational stability of the power distribution system.

[0022] The base unit rotator is installed on the surface of the plug-in box via a rotating interface. Power supply operation only requires installing the base unit rotator, driving the power supply structure to rotate, and connecting the protrusion for fixation. The rotating interface design eliminates the need for complex assembly when connecting the base unit rotator to the power supply structure. Maintenance personnel can complete the installation without specialized tools, significantly improving ease of operation. The process logic of inserting and rotating the connecting post for fixation is clear and does not rely on the operator's experience judgment (such as the need for tactile confirmation of proper positioning in traditional manual rotation). Power supply fixation can be completed simply by following the standard steps, lowering the operational threshold for maintenance personnel, reducing the risk of failure due to improper operation, and improving overall maintenance efficiency.

[0026] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0027] Implementation example:

[0028] like Figure 1-2The device shown is an electric rotary power take-up head on a plug-in box, which is used to solve the problems of large space occupation and insufficient automation of traditional manual power take-up heads in the scenario of intelligent sliding contact type small busbar (rotary) in data centers. It includes a power take-up structure 1 that extends out from the plug-in box 4, and a base rotator 2 that drives the power take-up structure 1 to rotate. The base rotator 2 is connected to the power take-up structure 1 through the rotation interface on the surface of the plug-in box 4, forming a modular design with built-in execution and external drive, which ensures both structural compactness and ease of later maintenance and operation.

[0029] The power-taking structure 1 is the core execution unit for the device of this application to connect and take power from the busbar trough 3. It is integrated vertically along the plug-in box 4 and includes a connecting post 11, a rotating base (not shown in the figure), and a power-taking head 12. The connecting post 11 is a cylindrical structure made of insulating material with a diameter that matches the inner diameter of the interface of the busbar trough 3. It protrudes vertically upward from the upper end face of the plug-in box 4, and the protrusion height is such that the power-taking head can contact the busbar conductor after being inserted into the busbar trough 3. The connecting post 11 has radially symmetrical connecting protrusions 13 on its side, and the ends of the protrusions adopt an arc transition design to fit with the connecting grooves in the busbar trough 3. The connecting post 11 serves as the physical connection carrier between the power-taking structure and the busbar trough 3. On the one hand, it provides an installation base for the power-taking head 12. On the other hand, through the cooperation of the side connecting protrusions 13 with the connecting grooves in the busbar trough 3, it fixes the power-taking structure in the busbar trough 3 and prevents the power-taking head from being displaced due to vibration or external force.

[0030] The rotating base is located inside the plug-in box 4, directly below the connecting column 11, and is fixedly connected to the inner wall of the plug-in box 4 via a flange. It integrates a gear transmission mechanism, with the driven gear coaxially fixed to the lower end of the connecting column, and the driving gear extending to the surface of the plug-in box via a rotating shaft to form a rotating interface. Positioning teeth are set on the inner wall of the interface for docking with the base rotator 2. The rotating interface is limited by a limiting block to achieve only a 90-degree reciprocating rotation, ensuring that the connecting protrusion can be accurately aligned with the connecting groove in the busbar trough 3. As the core of the power-taking structure's rotation drive, the rotating base receives the torque transmitted by the base rotator 2 and drives the connecting column and the power-taking head 12 to rotate synchronously via gear transmission, achieving contact and separation between the power-taking head 12 and the busbar conductor. Simultaneously, mechanical limiting ensures accurate rotation angle, preventing excessive rotation and component damage.

[0031] The power take-up head 12 is made of a highly conductive metal material and is fixed to the upper surface of the connecting post 11. A conductive contact is located on the top, and the contact surface is electroplated with a wear-resistant conductive layer. An insulating protective sleeve covers the outside of the power take-up head 12, exposing only the top conductive contact to prevent accidental conduction in non-power-taking areas. Current and temperature sensors are also installed to monitor the current and temperature at the contact point in real time. The power take-up head directly contacts the busbar conductor in the busbar trunking, enabling the transmission of electrical energy from the busbar to the plug-in box. The wear-resistant conductive layer reduces wear caused by long-term contact friction, extending the service life of the power take-up head, while ensuring stable current transmission and preventing localized overheating caused by poor contact.

[0032] The base rotator 2 is an external drive unit that drives the power-taking structure to rotate. It is a detachable component and is installed on the surface of the plug box when switching power-taking states. The docking interface is located on the top of the base rotator and is an internal gear sleeve structure that is adapted to the rotating interface of the base. The number of teeth and tooth shape of the internal gear sleeve are completely matched with the positioning teeth of the rotating interface. During installation, the internal gear sleeve and the rotating interface are nested to form circumferential positioning, ensuring that the torque can be stably transmitted to the rotating base.

[0033] The base machine rotator 2 has manual and remote modes. The manual mode is achieved via a handle located on the end face of the rotator, which is fixedly connected to an internal drive shaft. Turning the handle rotates the docking interface via the drive shaft, thus driving the base machine to rotate. The base machine rotator incorporates a signal processing unit, an alarm unit, and a wireless communication module. The signal processing unit filters and reduces noise from the received raw data (eliminating noise signals generated by electromagnetic interference from the current sensor and correcting ambient temperature deviations from the temperature sensor) to ensure data accuracy. Simultaneously, through a preset calibration algorithm, it converts the analog signals output by the sensors into directly identifiable digital signals (e.g., converting analog current to specific current values ​​and analog temperature to degrees Celsius values), providing a reliable data foundation for subsequent analysis and judgment. The signal processing unit presets safety parameter thresholds (e.g., the rated current range of the power supply circuit and the normal operating temperature range of the power supply head), comparing the pre-processed real-time data with these thresholds. If the data exceeds the threshold (e.g., current overload, excessive temperature), an abnormal warning trigger signal is immediately generated and transmitted to the alarm unit and the wireless communication module, initiating the subsequent warning process. Based on the judgment results of the signal processing unit, the alarm unit provides risk warnings through a dual approach of local audible and visual alerts and remote information push notifications. This ensures that maintenance personnel can promptly detect anomalies. The audible and visual alarm unit consists of an LED indicator and a buzzer mounted on the surface of the connector box. When an anomaly warning signal is received from the signal processing unit, the LED indicator flashes at a high frequency, and the buzzer emits an intermittent alarm sound. Simultaneously with triggering the local audible and visual alarm, information such as the anomaly type (e.g., current overload, overtemperature), the time of the anomaly, and the corresponding connector box number are integrated into a standard alarm command, which is then synchronously pushed to the control backend via the wireless communication module to notify maintenance personnel. The wireless communication module is the core component for enabling intelligent remote operation of the device and uploading of monitoring data. Its function focuses on bidirectional signal transmission and operational reliability. It supports receiving remote operation commands sent from the control backend or maintenance personnel's mobile terminals (e.g., mobile phones), driving the power supply structure to rotate in a non-contact manner.

[0034] In use, move the assembled power-taking structure 1 plug box 4 to the bottom of the target busbar trough 3, align the connecting post with the interface of the busbar trough 3, and push the plug box 4 vertically upward until the connecting post 11 is fully inserted into the busbar trough 3. At this time, the conductive contact at the top of the power-taking head contacts the busbar conductor in the busbar trough 3, completing the initial power-taking connection. Align the base rotator 2 with the rotating interface to complete the fixed installation. After confirming that the load of the plug box 4 has been disconnected, the operator drives the connecting post 11 to rotate remotely. At this time, the connecting protrusion 13 on the side of the connecting post 11 rotates to the position of the connecting block in the busbar trough 3 and enters the connecting groove, completing the fixation of the power-taking structure 1 in the busbar trough 3. The power-taking head 12 officially enters the working state and can connect the load of the plug box 4 to achieve power supply.

[0035] This application's device uses a base rotator to electrically drive the power-taking head to rotate, replacing traditional manual operation. It also supports wireless remote control, reducing human intervention. Equipped with signal processing, an alarm unit, and a wireless communication module, it can monitor the power-taking current and temperature in real time, triggering audible and visual alarms and remote alarms when thresholds are exceeded. This solves the problems of traditional manual power taking lack of monitoring and early warning, adapting to the intelligent operation and maintenance needs of data centers. The device adopts a plug-in box insertion method followed by power taking, integrating the power-taking structure within the plug-in box. This eliminates the need for redundant space for manual operation, and adjacent plug-in boxes only require basic heat dissipation spacing, meeting the high-density layout requirements of data centers. Remote control reduces close contact between personnel and high-voltage areas, while manual mode provides emergency backup. The guide design connecting the protrusions and grooves, along with the rotating base angle limit, reduces operational difficulty and the risk of poor contact, improving operational efficiency.
