Description

Technical Field

[0001] This invention relates to the field of photovoltaic green electricity distribution, specifically to an unmanned intelligent photovoltaic green electricity distribution device for mines that integrates source, grid, load, and storage. Background Technology

[0002] Unmanned mines operate in harsh environments, with issues such as strong site vibrations, complex terrain, high dust and moisture content, and large outdoor temperature differences. This places extremely high demands on the stability, adaptability, and protective performance of photovoltaic green electricity distribution equipment.

[0003] Currently, most photovoltaic (PV) green electricity distribution in mines uses traditional, single-structure power distribution equipment, lacking targeted vibration reduction and attitude control mechanisms. This makes them susceptible to displacement or component damage due to mine site vibrations and terrain subsidence, leading to power transmission interruptions. Furthermore, the photovoltaic power conversion efficiency of existing equipment is low, making it difficult to adapt to fluctuating scenarios with multiple PV power supplies, resulting in unreliable power quality. The lack of efficient grid-source integration modules also leads to voltage mismatches and grid impacts, hindering coordinated operation of the power source, grid, load, and storage systems. In addition, existing equipment lacks flexibility in energy storage integration, is difficult to maintain, and lacks comprehensive remote control capabilities, making it unsuitable for unmanned operations in unmanned mines. Moreover, inadequate protection and heat dissipation designs make internal electrical components vulnerable to dust, moisture corrosion, or overheating, resulting in short equipment lifespans and high failure rates, failing to meet the long-term, stable green electricity distribution needs of unmanned mines. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an unmanned intelligent distribution device for photovoltaic green electricity in mines that integrates source, grid, load, and storage.

[0008] Furthermore, the flexible connection assembly includes a connecting plate fixed to the bottom of the source-grid adapter box and the top of the energy storage distribution box, and a flexible support is provided between the connecting plates.

[0009] Furthermore, the fixing component includes threaded sleeves rotatably connected to the four corners of the top of the power supply adapter box, and the threaded sleeves are internally threaded with studs, which are fixedly connected to the power supply connection box.

[0010] Furthermore, a ball head and a socket are provided at the center of the cable channel, which are used to connect the power grid adapter box and the energy storage distribution box in conjunction with the flexible connection component.

[0012] Furthermore, multiple power sockets are provided on both sides of the power connection box, and a protective cover is provided on the top of the power connection box. The protective cover is located at the power socket and is an openable cover.

[0013] The beneficial effects of this invention are: Improve equipment operation and adapt to complex mining conditions: The base and expansion bolts are firmly fixed together, and a multi-level shock absorption structure is formed by nested shock absorption components, which effectively reduces the vibration and impact of the mining site. Combined with the closed-loop control of the attitude detection module and electric push rod, the horizontal attitude of the support plate and the equipment above can be automatically adjusted to adapt to uneven mining sites, avoid equipment failure due to unstable foundation or attitude deviation, and greatly improve the operational stability of the equipment in harsh environments.

[0025] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0026] See Figures 1-7 This is a schematic diagram of the structure of the present invention, which is a source-grid-load-storage coordinated photovoltaic green electricity intelligent distribution device for unmanned mines. It includes a base 1 fixed to the ground by expansion bolts. The base 1 serves as the load-bearing foundation of the entire device. It is firmly connected to the ground by expansion bolts, which can resist the impact of vibration, wind and terrain settlement in the unmanned mine site, and provide stable installation support for the entire device, so as to avoid the device from shifting or being damaged due to unstable foundation.

[0027] The top of the base 1 is equipped with a nested shock-absorbing component for attitude adjustment. Above the nested shock-absorbing component is an energy storage distribution box 8. The energy storage distribution box 8 serves as the mounting carrier for the energy storage interface and control module, protecting the internal components and ensuring the stable operation of energy storage distribution. It is suitable for the complex outdoor working conditions of unmanned mines and can effectively isolate dust and moisture from corroding the internal components. The left side of the interior of the energy storage distribution box 8 is connected to the energy storage interface compartment 10 for docking with external energy storage batteries via a slide rail 9. The slide rail 9 allows for flexible pulling of the energy storage interface compartment 10, facilitating the inspection, maintenance, and replacement of the wiring and interfaces inside the interface compartment, reducing the difficulty of outdoor maintenance in unmanned mines. The energy storage interface compartment 10 integrates multiple interfaces for external energy storage batteries of different specifications and has overcurrent, overvoltage, and short-circuit protection functions. It can achieve rapid docking with various energy storage devices, receiving electrical energy from external energy storage batteries and transmitting control signals from the energy storage distribution box to the energy storage devices, ensuring a stable connection of the energy storage process.

[0028] Inside the energy storage distribution box 8, on the right side, is a distribution control box 11 that issues distribution commands. The distribution control box 11 is the core control unit of the energy storage distribution process. It has a built-in controller, signal processing module, and power management module. It can receive various signals transmitted from the power grid adapter box, power connection box, and wireless communication module. Combined with the power demand of the unmanned mine, the photovoltaic power supply status, and the remaining power of the energy storage, it can intelligently generate power distribution commands and regulate the storage, output, and distribution ratio of power. It also has fault detection, alarm, and emergency handling functions. When a component malfunctions, it can quickly cut off the corresponding circuit to ensure the safety of equipment and mine power supply.

[0029] A flexible connection component is installed above the energy storage distribution box 8, and a power grid adapter box 14 is installed above the flexible connection component. The power grid adapter box 14 is used to connect the photovoltaic rectifier module and the mining microgrid, and plays a core role in power conversion adaptation and grid connection. The internal area is planned with independent installation area to avoid signal interference between different modules and ensure the stability of power conversion and grid connection. The left side of the inside of the power grid adapter box 14 is connected to a swing bracket 15 through a rotating shaft. The rotating shaft can drive the swing bracket 15 to flexibly adjust the angle to adapt to the installation angle of the dual photovoltaic rectifier compartment 16. This design facilitates both speed and ease of later inspection and maintenance of the rectifier compartment. The swing bracket 15 is equipped with a dual-path photovoltaic rectifier compartment 16 for current conversion. The dual-path photovoltaic rectifier compartment 16 is the core component for photovoltaic power conversion. It has two independent rectifier modules built in, which can simultaneously receive DC power from two photovoltaic modules and convert it into AC power that meets the needs of the mine microgrid and electrical equipment. It features high rectification efficiency, strong stability, and outstanding anti-interference ability, making it suitable for the fluctuating scenarios of photovoltaic power supply in unmanned mines. It can effectively filter out noise in photovoltaic power and ensure the quality of output power.

[0030] Inside the source-grid adapter box 14, on the right side, is a mining microgrid connection compartment 17 for connecting to the mining power grid. The mining microgrid connection compartment 17 integrates a grid connection interface, a voltage regulation module, and a lightning protection module, enabling rapid connection with the mining microgrid. It is responsible for transmitting the converted electrical energy to the mining microgrid, while simultaneously receiving the operating signals of the mining microgrid and feeding them back to the control unit. This achieves source-grid collaborative adaptation, avoiding problems such as voltage mismatch and grid impact during power transmission, and ensuring the smooth integration of photovoltaic green electricity into the mining microgrid. Inside the energy storage distribution box 8 and the source-grid adapter box 14, there is a cable channel 18. The cable channel 18 is used to organize various cables inside the equipment, including power cables and signal cables, separating different types of cables to avoid cable tangling and wear. It also serves to protect the cables, reducing the risk of cable compression and damage, and ensuring the smooth transmission of electrical energy and signals.

[0031] The power connection box 20 is connected to the top of the source network adapter box 14 via a fastener 19. The power connection box 20 serves as the wiring carrier for various electrical equipment in the mine. A wireless communication module 21 is installed at the top center of the power connection box 20, which enables wireless data interaction between the equipment and the mine's central control system and remote monitoring platform. It is responsible for uploading data such as equipment operating parameters, power distribution, and fault alarm information, and at the same time, it receives remote control commands to realize remote monitoring, parameter debugging, and command issuance of the equipment. This adapts to the unmanned operation requirements of unmanned mines and reduces the workload of manual on-site operation.

[0032] The nested shock absorption assembly includes an outer fixing cylinder 2 arranged in a triangle on the base 1. The outer fixing cylinder 2 is made of high-strength alloy material, and its triangular arrangement maximizes the stability of the assembly, providing a fixed installation space for the middle buffer cylinder 3. It also protects the internal buffer structure from damage caused by external dust and impacts. The middle buffer cylinder 3 is inserted into the outer fixing cylinder 2, and the middle buffer cylinder 3 and the outer fixing cylinder 2 are fitted with a clearance to allow for vertical buffer displacement. This, combined with the inner support column 4, completes the shock absorption function and also acts as a guide to prevent displacement during shock absorption. To ensure uniformity of vibration reduction, an inner support column 4 is inserted into the top of the inner buffer cylinder 3. This inner support column 4, as a direct component supporting the energy storage distribution box 8, transfers the weight of the energy storage distribution box to the buffer structure. Simultaneously, it expands and contracts vertically during vibration reduction, forming a multi-stage vibration reduction system with the inner buffer cylinder 3 and the buffer components. This reduces the impact of vibrations from the unmanned mining site on the equipment above. A support plate 7 is fixed to the top of the inner support column 4, connecting it to the energy storage distribution box 8, increasing the contact area, making the energy storage distribution box 8 more stable, and also dispersing the energy storage distribution box. To minimize weight and prevent excessive local stress that could damage components, an electric push rod 5 is installed between the inner support column 4 and the base 1. This electric push rod 5 acts as the actuator for attitude adjustment, receiving control signals from the attitude detection module 6 to perform telescopic movements. This, in turn, moves the inner support column 4 up and down, adjusting the height and horizontal position of the support plate 7 and the equipment above it. This adapts to the installation requirements of uneven mining sites, ensuring the overall equipment remains horizontally stable. An attitude detection module 6 is located at the center of the outer fixing cylinder 2 on the base 1. The attitude detection module 6 incorporates a gyroscope, tilt sensor, and other components, enabling... The system continuously monitors the overall horizontal posture, tilt angle, and vibration amplitude of the equipment. The detected posture data is converted into electrical signals and transmitted to the electric push rod 5 through the signal receiver head. This provides data support for the extension and retraction adjustment of the electric push rod 5, enabling automatic detection and precise adjustment of the equipment's posture. This ensures the stable operation of the equipment in complex mine terrain. The posture detection module 6 is connected to the electric push rod 5 through the signal receiver head. The signal receiver head is responsible for receiving the control signals transmitted by the posture detection module 6 and simultaneously feeding back the operating status signals of the electric push rod 5, forming a closed-loop control to ensure the accuracy and timeliness of posture adjustment.

[0033] Both sides of the energy storage distribution box 8 and the source-grid adapter box 14 are equipped with removable covers. These covers are secured with bolts, facilitating easy access for inspection, maintenance, replacement of internal components, and wiring tidying. They also provide excellent sealing performance, effectively preventing mine dust, moisture, rainwater, and other impurities from entering the box and protecting internal electrical components from corrosion. This makes them suitable for harsh outdoor mining conditions. A connection port is located on one side of the cover of the energy storage interface compartment 10, corresponding to the interface of the compartment for connecting external energy storage battery cables. Sealing gaskets are installed at the interfaces to improve sealing performance and prevent dust and moisture from entering the enclosure through the interfaces. They also serve to fix the cables and prevent poor contact caused by pulling or vibration. The enclosure cover is equipped with louvers for heat dissipation. The louvers adopt an inclined structure design, which can effectively block external dust and rainwater from entering the enclosure while ensuring heat dissipation and ventilation. This achieves a dual function of heat dissipation and protection, and can timely dissipate the heat generated by the electrical components inside the enclosure during operation, preventing components from aging and being damaged due to overheating, and ensuring the stable operation of the equipment for a long time.

[0034] The flexible connection assembly includes a connecting plate 12 fixed to the bottom of the source-grid adapter box 14 and the top of the energy storage distribution box 8. The connecting plate 12 is firmly connected to the source-grid adapter box 14 and the energy storage distribution box 8 respectively by bolts, providing a fixed installation point for the flexible support 13, and also serving to connect the two boxes, transferring the weight and force of the boxes. The flexible support 13 is set between the connecting plates 12, which can buffer the vibration generated during the operation of the equipment, and at the same time adapt to the slight relative displacement between the source-grid adapter box 14 and the energy storage distribution box 8, avoiding damage to the connection part between the two boxes due to excessive force caused by vibration or posture adjustment, ensuring the stability and safety of the box connection, and reducing the impact of vibration on the internal components of the box.

[0035] The fastener 19 includes threaded sleeves rotatably connected to the four corners of the top of the source network adapter box 14. The threaded sleeves are rotatably connected to the top of the source network adapter box 14 and can be connected to studs by rotation. The internal threads of the threaded sleeves are connected to studs, which are fixedly connected to the power connection box 20. This can stably transfer the weight of the power connection box 20 to the source network adapter box 14. At the same time, through the threaded engagement with the threaded sleeves, the power connection box 20 can be detached and installed, which is convenient for the later inspection and maintenance of the power connection box.

[0036] The cable channel 18 is equipped with a ball head and a ball socket at its center. The two work together to achieve multi-angle rotation, adapting to the deformation of the flexible connection components and the adjustment of the equipment posture. This prevents the cable channel 18 from breaking or being damaged due to relative displacement or posture adjustment of the box. At the same time, it can ensure that the cables inside the cable channel are not pulled, ensuring the stability of power transmission and signal transmission. The ball head and ball socket are used to connect the source network adapter box 14 and the energy storage distribution box 8 with the flexible connection components, further improving the flexibility and stability of the connection between the two boxes. This takes into account the dual requirements of flexible shock absorption and structural support, adapting to the complex working conditions of unmanned mines.

[0037] Both the source network adapter box 14 and the energy storage distribution box 8 are equipped with multiple cooling fans 23 for heat dissipation. The cooling fans 23 can automatically start and stop according to the temperature inside the box. By using forced ventilation, they can accelerate the air circulation inside and outside the box, and promptly remove the heat generated by the operation of the internal electrical components. This prevents the internal temperature from being too high, which could lead to a decline in component performance, accelerated aging, or failure. It ensures the stability of the equipment under long-term high-load operation and is suitable for high-temperature and high-load outdoor mining operations.

[0038] Multiple power sockets are installed on both sides of the power connection box 20. These sockets can simultaneously connect to various electrical equipment in the mine, including monitoring equipment, inspection equipment, and lighting equipment, adapting to different power and interface types. Each socket is equipped with an independent switch and protection device, allowing for individual circuit control to prevent single device failures from affecting the overall power supply. The top of the power connection box 20 is equipped with a protective cover 22 made of waterproof, dustproof, and impact-resistant material. This cover completely covers the top of the power connection box 20, effectively protecting the wireless communication module 21 and internal components from damage by rain, dust, and falling debris, thus improving the outdoor durability of the equipment. The protective cover 22 has an openable cover at the power socket location. The openable cover uses a snap-fit ​​structure, closing when the power socket is not in use to provide a sealing protection, preventing impurities from entering the socket and causing poor contact or short circuits. When in use, it can be opened flexibly without affecting cable access, balancing ease of use and protective performance.

[0039] When using this invention: During operation, the base 1 is fixed to the ground by expansion bolts to provide stable load-bearing for the equipment. At the same time, the nested shock absorption components are activated, and the outer fixing cylinder 2, the middle buffer cylinder 3 and the inner support column 4 form multi-level shock absorption. The attitude detection module 6 collects the equipment attitude data in real time and transmits it to the electric push rod 5. The attitude calibration is completed by adjusting the horizontal attitude of the support plate 7 and the equipment above through telescopic adjustment.

[0040] Subsequently, the source-grid adapter box 14 is activated, the swing bracket 15 adjusts its angle, the dual-path photovoltaic rectifier compartment 16 converts the photovoltaic DC power into standard AC power and filters out noise, the mine microgrid connection compartment 17 connects to the mine microgrid, transmits power and feeds back grid operation signals, simultaneously, the energy storage distribution box 8 is activated, the slide rail 9 drives the energy storage interface compartment 10 to connect to the external energy storage battery, and the distribution control box 11 integrates various signals and generates power distribution instructions based on the mine's power demand, photovoltaic power supply and energy storage capacity. The cable channel 18 ensures stable transmission of power and signals, the power connection box 20 supported by the fixing component 19 supplies power to the mine terminal equipment through the power socket, the wireless communication module 21 enables remote data interaction, adapts to unattended operation, and various protective and heat dissipation components continue to work to ensure the equipment stably completes the photovoltaic green power collaborative distribution operation.
