Description

Technical Field

[0001] This invention relates to the field of power supply equipment technology, and in particular to a honeycomb structure multi-cavity modular power supply management device. Background Technology

[0002] The coal mining industry is currently experiencing rapid development in the intelligentization of tunneling equipment, with tunneling faces shifting from single-equipment operation to integrated, equipment-group collaborative operation modes. As tunneling depth expands and high-power equipment is applied, power supply demands are becoming increasingly stringent: the traditional AC1140V power supply system is beginning to incorporate AC3300V due to the needs of high-power equipment and ultra-long-distance tunneling, resulting in the coexistence of two voltage levels.

[0003] Meanwhile, existing products on the market have obvious limitations: most load centers only support a single voltage level and cannot adapt to multi-voltage coexistence scenarios. Their functions are limited to basic power supply management, and they adopt a multi-point discrete structure, which makes it difficult to meet the needs of the current complex environment. At the same time, multiple circuits are concentrated inside an explosion-proof cavity, and failures can easily cause mutual interference and make maintenance inconvenient. If one circuit fails, the mechanical and electrical interlocks will automatically cut off the power during maintenance, causing other normal circuits to also trip, resulting in a large-scale power outage and posing a serious threat to the power distribution safety in the mine.

[0004] Therefore, there is an urgent need for a modular power supply management device based on a honeycomb structure multi-cavity power supply. Summary of the Invention

[0005] This invention provides a solution to the aforementioned problems existing in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A honeycomb-structured multi-cavity modular power supply management device includes: The honeycomb-inspired structural unit is composed of multiple hexagonal basic units spliced ​​together. Multiple independent explosion-proof chambers are divided into a drive unit chamber, a power supply unit chamber, a remote control unit chamber, a lighting integrated protection unit chamber, and a display unit chamber based on a honeycomb biomimetic structure; A through-wall terminal connection assembly includes a through-wall terminal female contact fixed to a terminal fixing plate and a through-wall terminal male contact that plugs into it; The manual cutting structure connects to the through-wall terminal connection assembly to form a pluggable unit module structure; An isolation chamber is located between the incoming and outgoing sides, connecting the AC1140 and AC3300 voltage circuits. The housing and its supporting structures include an explosion-proof expansion structure, a quick-access side sliding door, a quick-access cable insertion / removal structure on the inlet side, and a quick-access cable insertion / removal structure on the outlet side.

[0007] Among them, in the honeycomb biomimetic structural unit, the hexagonal basic units are seamlessly spliced ​​together in an edge-to-edge manner; In three-dimensional space, six hexagonal units form a closed loop around a central hexagonal unit, constructing a compact functional unit group; Hexagonal units form a finite gap filling structure through angle adaptation.

[0008] Among them, the female contact of the through-wall terminal has an embedded finger-type conductor; The finger-type conductor and the male contact of the through-wall terminal form a plug-in contact structure, which has a follow-up electrical connection mechanism; The plug-in structure adopts a handcart-isolated disconnection method and has an electrical isolation status indicator.

[0009] The incoming line side quick-plug cable structure is equipped with AC1140 and AC3300 dual voltage access ports. The outgoing side features a quick-plug cable structure with multiple output ports. A voltage level conversion device is installed inside the isolation chamber to connect high and low voltage circuits and form physical isolation.

[0010] The honeycomb-inspired structural units are connected by rectangular cross-section copper busbars. The copper busbar is not wrapped with an insulating layer, is exposed to the air, and is in contact with the housing; The copper busbar is fixedly connected to the through-wall terminal female contact by bolts, forming a rigid electrical path.

[0011] The shell is made of low-alloy high-strength structural steel and was designed based on static analysis. A fast-sliding side door is provided on the front side of the housing as a maintenance and inspection access; The explosion-proof extension structure is located on the left side of the housing and has a connection interface with an extension device, including an explosion-proof transformer, a load switch, or a vacuum feeder switch.

[0012] The hexagonal basic unit has rounded corner transition structures at each corner; The gaps between the units form a honeycomb-like laminar flow channel, creating a structure for directional airflow.

[0013] This includes: The push-type cutting structure has a built-in torque sensor and electrical contact signal detection module; The detection module collects torque parameters and electrical contact status signals during the insertion and removal process; The control system includes a high and low voltage circuit locking mechanism and a safety interlock mechanism, which are electrically connected to the detection module.

[0014] Among them, the honeycomb laminar flow channels form a network with uniform heat distribution; The walls of each independent explosion-proof cavity are thermally connected to the overall structure; The rounded corner transition structure forms an airflow guiding channel.

[0015] The isolation chamber integrates an electromagnetic compatibility protection circuit. The hexagonal cavity formed by the honeycomb biomimetic structural units has an electromagnetic shielding structure; The copper busbar connectors are rigidly fixed, and electromagnetic coupling is used between control modules; The voltage level conversion device includes an uninterrupted switching mechanism between AC1140 and AC3300 voltages.

[0016] Compared with the prior art, the present invention has the following advantages: This solution addresses the challenges of complex cable layouts and difficult power supply and distribution management caused by the coexistence of AC1140 and AC3300 voltages at the tunneling face. It overcomes the limitations of traditional equipment with its single function and dispersed structure, adapting to the demands of integrated and intelligent operations. Based on a honeycomb structure and biomimetic design, it develops independent operating drive units with cuttable and retractable characteristics, achieving both efficient space utilization and high-efficiency heat dissipation. For the confined spaces of thin coal seams below two meters, it resolves the contradiction between high power output and ease of installation within limited space, developing a high-power-density centralized power supply platform suitable for tunneling faces in thin coal seams below 2 meters. Furthermore, it studies the connection methods of drive units and control circuits within the entire electrical system, proposing a novel quick-connect structure to enable rapid docking of modular drive units and control circuits.

[0017] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention.

Detailed Implementation

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] This invention provides a honeycomb-structured multi-cavity modular power supply management device, comprising: The honeycomb-inspired structural unit is composed of multiple hexagonal basic units spliced ​​together. Multiple independent explosion-proof chambers are divided into a drive unit chamber, a power supply unit chamber, a remote control unit chamber, a lighting integrated protection unit chamber, and a display unit chamber based on a honeycomb biomimetic structure; A through-wall terminal connection assembly includes a through-wall terminal female contact fixed to a terminal fixing plate and a through-wall terminal male contact that plugs into it; The manual cutting structure connects to the through-wall terminal connection assembly to form a pluggable unit module structure; An isolation chamber is located between the incoming and outgoing sides, connecting the AC1140 and AC3300 voltage circuits. The housing and its supporting structures include an explosion-proof expansion structure, a quick-access side sliding door, a quick-access cable insertion / removal structure on the inlet side, and a quick-access cable insertion / removal structure on the outlet side.

[0023] The working principle and beneficial effects of the above technical solution are as follows: Figure 1 As shown, this invention constructs a modular power supply management device based on a honeycomb biomimetic structure. The device includes a honeycomb biomimetic structure unit 2, which is composed of multiple hexagonal basic units assembled in a specific manner. The honeycomb biomimetic structure unit 2 is a honeycomb structure or a hexagonal modular unit. Multiple independent explosion-proof cavities are divided according to the honeycomb biomimetic structure into a drive unit cavity, a power supply unit cavity, a remote control unit cavity, a lighting integrated protection unit cavity, and a display unit cavity. These multiple independent explosion-proof cavities are either explosion-proof shells or commercially available flameproof cavities.

[0024] like Figure 2 As shown, the through-wall terminal connection assembly includes a through-wall terminal female contact 7 and a matching through-wall terminal male contact 9 mounted on a terminal fixing plate 8. The through-wall terminal connection assembly is usually made by drilling or stamping on the terminal fixing plate. By setting the through-wall terminal to a plug-in structure, a "quick connection" is formed, thereby improving the connection efficiency.

[0025] With the above-described structural layout, the honeycomb bionic structural unit 2 serves as the foundation layer supporting the drive unit cavity and the power supply unit cavity. It needs to be made of explosion-proof material. In addition to ensuring explosion-proofness, it also needs to have a certain mechanical strength and be able to be made into a composite material with each functional cavity. The drive unit cavity is used for drive control, and the power supply unit cavity, in addition to forming an independent power supply to improve power supply performance, also needs to play a role in voltage regulation. Thus, this application can be made into a plate-shaped power supply device or a vertical power supply cabinet.

[0026] The mention of achieving explosion protection through multiple independent chambers requires each chamber to be set as an independent explosion protection structure. However, because the traditional single-chamber structure has limited adaptability, single-chamber explosion protection devices are usually not modularized or have very little modularization after being manufactured as power supply or control equipment. Therefore, the single-chamber structure is only suitable for power supply structures with relatively simple functions, such as single voltage or single function.

[0027] To increase the applicability of this application, and to enable secondary functional expansion after the power supply or control device is manufactured, multiple independent explosion-proof cavities are composed of several functional components. The functional components are arranged vertically and interconnected. Each functional component consists of several functional units. Adjacent functional units are connected by a push-type cutting structure 6. A functional unit is also connected to two adjacent functional units above and below it via a push-type cutting structure 6. Simultaneously, a functional unit is also connected to two adjacent functional units on the left and right. The functional units have a certain degree of pullability in the horizontal direction. By setting the push-type cutting structure 6, the functional units also have a certain degree of pullability in the vertical direction, thereby allowing the manufactured power supply or control device to have a greater degree of freedom in functional expansion.

[0028] In another embodiment, in the honeycomb biomimetic structural unit, the hexagonal basic units are seamlessly spliced ​​together in an edge-to-edge manner; In three-dimensional space, six hexagonal units form a closed loop around a central hexagonal unit, constructing a compact functional unit group; Hexagonal units form a finite gap filling structure through angle adaptation.

[0029] The working principle and beneficial effects of the above technical solution are as follows: by setting 6 hexagonal units around 1 central hexagonal unit, a planar honeycomb structure can be assembled into a three-dimensional structure; by angle adaptation, the planar honeycomb structure can be assembled into a finite gap filling structure, but expansion along the planar direction is still possible. It also includes more hexagonal basic units, connecting segments and fasteners. Each hexagonal basic unit has angle adaptation characteristics, there is a connection distance between the fastener and each unit, and there is an assembly distance between the fastener and the edge of the adjacent unit, thereby ensuring that it can be assembled in three-dimensional space.

[0030] Seamless edge-to-edge splicing minimizes space waste, increasing space utilization to over 95% compared to traditional square module layouts. Six hexagonal units surrounding a central hexagonal unit form a closed-loop structure, enhancing overall structural strength and providing better protection for internal functional modules. Angle-adaptive design creates a limited-gap filling structure, ensuring sufficient space for assembly while avoiding excessive space waste.

[0031] In another embodiment, a finger-type conductor is embedded inside the female contact of the through-wall terminal; The finger-type conductor and the male contact of the through-wall terminal form a plug-in contact structure, which has a follow-up electrical connection mechanism; The plug-in structure adopts a handcart-isolated disconnection method and has an electrical isolation status indicator.

[0032] The working principle and beneficial effects of the above technical solution are as follows: During implementation, the through-wall terminal female contact 7 includes a finger-type conductive body, a fixing part, and a connecting part. The finger-type conductive body is perpendicular to the fixing part and arranged along the direction shown in the figure. The finger-type conductive body and the fixing part have an embedding depth, such as... Figure 3 As shown, this ensures that when the male contact 9 of the through-wall terminal is inserted, the finger-type conductor can have sufficient contact area.

[0033] One end of the finger-type conductor is connected to the inner wall of the female contact 7 of the through-wall terminal, and the other end is connected to the surface of the male contact 9 of the through-wall terminal, so that the finger-type conductor forms an elastic contact structure as shown in the figure; the outer surface of the male contact 9 of the through-wall terminal is connected to the inner surface of the finger-type conductor, forming a plug-in contact structure as shown in the figure.

[0034] One end of the plug-in contact structure is connected to the handcart isolation device, and the other end is connected to the electrical isolation device. When the operator pulls the handcart isolation device, the plug-in contact structure can be visually disconnected. The plug-in contact structure usually adopts a spring design, which ensures that the finger conductor has a sufficiently large contact pressure, and effectively avoids excessive contact resistance when the plug-in structure is used as a connection.

[0035] The embedded design of the finger-type conductor significantly increases the electrical contact area, reduces contact resistance, and improves current carrying capacity. The plug-in contact structure ensures contact reliability in the vibration environment of coal mines, avoiding problems such as arcing and overheating caused by poor contact. The handcart isolation disconnect provides intuitive safety assurance, allowing operators to clearly judge the electrical isolation status and effectively preventing accidents caused by live operation.

[0036] In another embodiment, the incoming side quick-plug cable structure is configured with AC1140 and AC3300 dual voltage access ports; The outgoing side features a quick-plug cable structure with multiple output ports. A voltage level conversion device is installed inside the isolation chamber to connect high and low voltage circuits and form physical isolation.

[0037] The working principle and beneficial effects of the above technical solution are as follows: By setting up the quick-plug cable structure 1 on the inlet side, 1140V and 3300V cables can be connected to the device respectively; by setting up the quick-plug cable structure 5 on the outlet side, different voltages can be output to various load devices. However, for voltage level conversion, a special conversion device is still required, which also includes a voltage level conversion device, a high-voltage isolation unit, a low-voltage isolation unit, and a voltage detection unit. There is an insulation distance between the voltage level conversion device and the high-voltage isolation unit, a detection distance between the voltage detection unit and the low-voltage isolation unit, and a monitoring distance between the voltage detection unit and the input terminal of the adjacent high-voltage isolation unit. This ensures that voltage conversion can be performed inside the isolation chamber 4.

[0038] The input end of the incoming-side quick-plug cable structure 1 is connected to the high-voltage input end of the adjacent voltage level conversion device, and the other end is connected to the low-voltage input end. The other end of the voltage level conversion device is connected to one end of the high-voltage isolation unit, so that the incoming-side quick-plug cable structure 1, the voltage level conversion device and the high-voltage isolation unit form a dual-voltage input structure as shown in the figure. The other end of the low-voltage isolation unit is connected to one end of the voltage detection unit, and the other end of the voltage detection unit is connected to the output end of the adjacent outgoing-side quick-plug cable structure 5, so that the low-voltage isolation unit, the voltage detection unit and the outgoing-side quick-plug cable structure 5 form a multi-port output structure.

[0039] The dual-voltage access system solves the power supply problem of multiple voltages coexisting at the tunneling face, allowing a single device to meet the power supply needs of equipment with different voltage levels. The multiple output ports enhance the flexibility of the power supply system, enabling flexible allocation of power resources according to operational requirements. The application of a voltage level conversion device ensures absolute safety isolation between high and low voltage circuits, effectively preventing equipment damage and personal injury accidents caused by voltage surges.

[0040] In another embodiment, the honeycomb biomimetic structural units are connected by rectangular cross-section copper busbars; The copper busbar is not wrapped with an insulating layer, is exposed to the air, and is in contact with the housing; The copper busbar is fixedly connected to the through-wall terminal female contact by bolts, forming a rigid electrical path.

[0041] The working principle and beneficial effects of the above technical solution are as follows: Each honeycomb bionic structural unit 2 can be connected by setting rectangular cross-section copper busbars; direct heat dissipation can be achieved through the absence of an insulating layer, but a reliable fixing method is still required for the stability of the electrical connection. It also includes bolt fixing devices, thermal pads, vibration buffer devices, and grounding devices. The bolt fixing devices and thermal pads have a clamping force, the vibration buffer devices and grounding devices have a buffer distance, and the vibration buffer devices and the fixed ends of adjacent rectangular cross-section copper busbars have a shock-absorbing distance, thereby ensuring a stable connection of the rectangular cross-section copper busbars.

[0042] One end of the rectangular cross-section copper busbar is connected to the connection end of the adjacent honeycomb bionic structural unit, and the other end is connected to the fixed end of the through-wall terminal female contact. The other end of the bolt fixing device is connected to one end of the thermally conductive pad, so that the rectangular cross-section copper busbar, the bolt fixing device and the thermally conductive pad form a rigid connection structure as shown in the figure. The other end of the vibration buffer device is connected to one end of the grounding device, and the other end of the grounding device is connected to the grounding end of the adjacent rectangular cross-section copper busbar, so that the vibration buffer device, the grounding device and the rectangular cross-section copper busbar form an anti-vibration structure as shown in the figure.

[0043] Compared to traditional round cables, rectangular cross-section copper busbars have a larger surface area to volume ratio, increasing current carrying capacity by more than 50%. The insulation-free design significantly improves heat dissipation efficiency, effectively preventing overheating during high-load operation. Bolted connections eliminate the risk of loosening that can occur with flexible connections, ensuring long-term electrical connection reliability while facilitating troubleshooting and maintenance.

[0044] In another embodiment, the housing is made of low-alloy high-strength structural steel and designed based on static analysis. A fast-sliding side door is provided on the front side of the housing as a maintenance and inspection access; The explosion-proof extension structure is located on the left side of the housing and has a connection interface with an extension device, including an explosion-proof transformer, a load switch, or a vacuum feeder switch.

[0045] The working principle and beneficial effects of the above technical solution are as follows: It also provides a mobile complete set of equipment for underground coal mines, including a power supply device and a control device installed underground. An explosion-proof expansion structure 3 is provided between the power supply device and the control device. The interface of the explosion-proof expansion structure 3 is connected to the outer shell of the device. The explosion-proof expansion structure 3 is made of a honeycomb structure multi-cavity modular power supply management device.

[0046] It also provides a mobile complete set of equipment for underground coal mines, including a power supply device and a control device installed underground, as well as a fast side sliding door. The fast side sliding door is installed on the front side of the shell, and both ends of the fast side sliding door are connected to the inner wall of the shell. The fast side sliding door is made of the maintenance and repair channel of the aforementioned honeycomb structure multi-cavity modular power supply management device.

[0047] The front end of the housing is connected to the guide rail end of the adjacent fast-moving side door, and the other end is connected to the interface end of the explosion-proof expansion structure. The other end of the fast-moving side door is connected to one end of the sliding mechanism, so that the housing, the fast-moving side door and the sliding mechanism form a maintenance and repair channel. The other end of the explosion-proof expansion structure is connected to one end of the expansion device, and the other end of the expansion device is connected to the connection end of the adjacent downhole mobile complete set of equipment, so that the explosion-proof expansion structure, the expansion device and the downhole mobile complete set of equipment form an expansion structure.

[0048] The application of low-alloy high-strength structural steel ensures the structural safety and service life of the equipment in harsh downhole environments. Lightweight design guided by static simulation analysis reduces equipment weight while maintaining safety, simplifying transportation and installation. The fast-access side-sliding door design significantly improves maintenance efficiency, reduces equipment downtime, and enhances the overall availability of the power supply system. Standardized explosion-proof expansion interfaces facilitate equipment upgrades, enhancing the system's adaptability and scalability.

[0049] In another embodiment, the corners of the hexagonal basic unit are designed with rounded transition structures. The gaps between the units form a honeycomb-like laminar flow channel, creating a structure for directional airflow.

[0050] The working principle and beneficial effects of the above technical solution are as follows: The hexagonal basic unit adopts rounded corner transitions at each corner, a treatment method derived from in-depth research on fluid mechanics. When the cooling airflow passes through the inside of the device, the traditional right-angled structure will generate vortices at the corners, causing airflow turbulence. The rounded corner transition structure can guide the airflow to smoothly change direction, avoiding the formation of dead zones at the corners. The gaps naturally formed between the various hexagonal units constitute a honeycomb-like airflow channel network. The width of these channels is precisely calculated to allow the cooling airflow to pass through in a laminar flow state. The airflow in a laminar flow state has the characteristics of good stability and high heat exchange efficiency, and can more effectively remove heat compared to a turbulent flow state, thereby improving the overall heat dissipation effect.

[0051] In another embodiment, the push-type cutting structure incorporates a torque sensor and an electrical contact signal detection module; The detection module collects torque parameters and electrical contact status signals during the insertion and removal process; The control system includes a high and low voltage circuit locking mechanism and a safety interlock mechanism, which are electrically connected to the detection module.

[0052] The working principle and beneficial effects of the above technical solution are as follows: The hand-push cutting structure integrates a precision torque sensor at its core. This sensor adopts a strain gauge design and can monitor torque changes in real time during the insertion and removal process. Simultaneously, an electrical contact signal detection module is set on the contact surface of the contact head, judging the contact state by changes in conductivity. When the operator pushes the module, the torque sensor first senses the magnitude of the pushing force and converts it into an electrical signal. The detection module simultaneously monitors the contact resistance value of the male and female contacts. These two signals are sent to the controller after passing through a signal conditioning circuit. The controller judges based on preset torque and resistance thresholds. When the torque reaches the set value and the resistance is below the critical value, it indicates that the connection is in place. At this time, the controller outputs a locking command, driving the locking mechanism to act, achieving synchronous locking of the high-voltage main circuit and the low-voltage control circuit. The entire process forms a closed-loop control, ensuring that the optimal connection state is achieved with each insertion and removal.

[0053] In another embodiment, the honeycomb laminar flow channels form a heat distribution uniformity network; The walls of each independent explosion-proof cavity are thermally connected to the overall structure; The rounded corner transition structure forms an airflow guiding channel.

[0054] The working principle and beneficial effects of the above technical solution are as follows: The honeycomb laminar flow channel forms a three-dimensional heat distribution network inside the device. The heat generated by each hexagonal unit is not confined to its own unit, but is conducted to adjacent units through the metal material of the cavity wall. Due to the special nature of the hexagonal structure, each unit is in contact with six surrounding units, forming a multi-path heat conduction network, effectively preventing excessive heat concentration in a certain area and the formation of a heat island. Each independent explosion-proof cavity is made of aluminum alloy material with good thermal conductivity, and the cavity wall thickness is optimized to meet both explosion-proof strength requirements and ensure good thermal conductivity. When a local unit heats up, the heat is quickly transferred through the cavity wall to the overall structural frame, and then dissipated to the environment through the large surface area of ​​the frame. Combined with the reduced airflow resistance from the rounded corner transition structure, the cooling airflow through the laminar flow channel can carry away the heat conducted to the surface with higher efficiency, forming a conduction-convection composite heat dissipation mechanism.

[0055] In another embodiment, an electromagnetic compatibility protection circuit is integrated inside the isolation cavity; The hexagonal cavity formed by the honeycomb biomimetic structural units has an electromagnetic shielding structure; The copper busbar connectors are rigidly fixed, and electromagnetic coupling is used between control modules; The voltage level conversion device includes an uninterrupted switching mechanism between AC1140 and AC3300 voltages.

[0056] The working principle and beneficial effects of the above technical solution are as follows: An electromagnetic compatibility protection circuit area is specially set up inside the isolation cavity. This area adopts a multi-layer printed circuit board structure, with grounding copper foil laid on the top and bottom layers of the circuit board, and signal lines running in the middle layer, forming a shielded sandwich structure. The hexagonal cavity of the honeycomb bionic structural unit itself is an excellent Faraday cage, and its continuous metal walls can effectively shield external electromagnetic interference. Copper busbars are used for electrical connection between the units. The rigid structure of the copper busbars ensures the stability of the connection and avoids electromagnetic radiation caused by positional changes in flexible cables due to vibration. During voltage level conversion, the intelligent control system inside the device first detects the current load status, then slowly builds up the new voltage through a pre-charging circuit. Only after the voltage stabilizes does it switch the main circuit. Throughout the process, the load side is always powered, achieving seamless switching between AC1140V and AC3300V, with voltage fluctuations controlled within 2% during the switching process.

[0057] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from the spirit and scope of this invention.
