[0032] like Figure 1 As shown, this utility model embodiment provides a modular mobile maintenance power supply platform, including:

[0033] Mobile vehicle base 1;

[0034] The energy storage power supply unit 2 is fixedly installed on the mobile vehicle base 1, and its internal part consists of a PMS compartment and a battery compartment that are isolated from each other.

[0035] The photovoltaic supplement unit 3 is movably connected to the top of the mobile vehicle base 1;

[0036] At least one functional instrument module 4;

[0037] The instrument module platform 11 of the mobile vehicle base 1 is provided with a first quick-connect female connector, and the bottom of the functional instrument module 4 is provided with a first quick-connect male connector coupled to the first quick-connect female connector. The functional instrument module 4 is detachably fixed and electrically connected to the mobile vehicle base 1 through the insertion and locking of the first quick-connect male connector and the first quick-connect female connector.

[0038] In this embodiment, the modular mobile maintenance power platform uses a mobile vehicle base 1 as its core load-bearing frame. The bottom is equipped with silent omnidirectional wheels with locking function, allowing for flexible movement on rough outdoor terrain and in narrow indoor passages within the substation. Locking the wheels ensures platform stability during operation. The mobile vehicle base 1 has an instrument module platform 11 on top, used to carry functional instrument modules 4; a fixed energy storage power supply unit 2 in the middle, whose interior is divided into an isolated PMS compartment and a battery compartment, respectively housing the power management system and the energy storage battery pack; and a photovoltaic supplement unit 3 connected to the top via a movable structure, forming a complete operational closed loop.

[0039] Before the operation, the staff pushes the mobile vehicle base 1 to the target area, locks the wheels, and adjusts the angle of the photovoltaic supplement unit 3 according to the sunlight to ensure it fully absorbs solar energy—part of the solar energy is directly supplied, and excess electrical energy is stored in the battery compartment of the energy storage power supply unit 2. This eliminates the reliance on the grid power supply box for traditional maintenance and avoids voltage fluctuations and the risk of electric shock from multiple power panels connected in series. Subsequently, according to the maintenance requirements, the first quick-connect male connector at the bottom of the functional instrument module 4 is aligned with the first quick-connect female connector on the instrument module platform 11 and pushed in to complete the mechanical fixation and electrical connection. The PMS compartment automatically identifies the module type and matches the power supply parameters, eliminating the need for manual adjustment.

[0040] During multi-interval maintenance, the platform can be moved by pushing the mobile carrier base 1. In narrow areas, the functional instrument modules 4 can be individually removed and carried for work. After maintenance, the photovoltaic supplement unit 3 can be folded to fit against the top of the mobile carrier base 1 to reduce space occupation. In the event of power grid failure or natural disaster, all functional instrument modules 4 can be removed, and the platform can be converted into a mobile emergency power source to power emergency lighting and communication equipment through the photovoltaic supplement unit 3 or the battery compartment, meeting the needs of improving efficiency and safety.

[0041] In some embodiments, the first quick-connect male connector includes at least a pair of guide rails, at least a set of electrical connectors, and at least one mechanical locking component; the first quick-connect female connector includes a guide groove that matches the guide rails, a socket that matches the electrical connectors, and a locking structure that cooperates with the mechanical locking component.

[0042] In this embodiment, the first quick-connect male connector integrates at least one pair of guide rails, at least one set of electrical connectors, and at least one mechanical locking component. Corresponding to the first quick-connect female connector, a guide groove, a socket, and a locking structure are provided, and the three work together to achieve efficient docking.

[0043] When installing the functional instrument module 4, first embed the guide rail into the guide groove of the instrument module platform 11, and push the module in along the groove—the gap between the guide groove and the guide rail should be controlled within 0.5mm to avoid misalignment and ensure that the electrical connector is accurately aligned with the socket. The electrical connector adopts a gold-plated multi-core structure, which has both excellent conductivity and mating resistance, with a single mating life of over 5000 cycles. It not only transmits working power but also transmits test data synchronously. The staff can view the results through the PMS compartment display screen of the energy storage power supply unit 2 without the need for additional data cables, thus solving the problem of messy cables in traditional maintenance.

[0044] After the module is pushed in until the electrical connector is fully inserted into the socket, the mechanical locking component automatically pops out and engages with the locking structure slot, completing the initial locking. For reinforced fixation, simply press the latch manually to achieve a tight engagement, preventing the module from loosening due to vibration. Unlocking requires only pressing the release button, and disassembly and assembly can be completed by a single person within 30 seconds without the need for tools, significantly improving module replacement efficiency. In emergency repairs, faulty modules can be quickly replaced, ensuring uninterrupted operation.

[0045] In some embodiments, the guide rail is a T-shaped guide rail, and the guide groove is a T-shaped groove; the mechanical locking component is a quick-release wrench with an eccentric cam, and the locking structure is a concave latch that engages with the eccentric cam.

[0046] In this embodiment, the guide rail adopts a T-shaped structure, the corresponding guide groove is a T-shaped groove, the mechanical locking component is a quick wrench with an eccentric cam, and the locking structure is a concave lock buckle, which is suitable for functional instrument modules 4 of different weights (5kg-30kg).

[0047] During installation, the T-shaped guide rail is pushed in along the T-slot. The protrusions on both sides of the slot form a "double-sided limit," distributing the module's weight and preventing structural deformation due to long-term use. It is suitable for heavy modules such as high-voltage withstand voltage testers. The T-slot opening is chamfered, allowing for quick alignment by feel even in low light conditions. After the module is pushed in place, the quick-release lever is turned clockwise. The internal eccentric cam rotates with the handle, and the distance between the eccentric center and the rotation axis gradually decreases, generating an increasing clamping force on the concave locking buckle. When the handle is turned horizontally, the locking force exceeds 500N, resisting vibrations caused by the movement of the mobile carrier base.

[0048] This design achieves strong locking with minimal force; operators only need to apply 10N of force to lock the module. Unlocking is achieved by simply turning the handle counter-clockwise, allowing for easy removal. Actual testing shows that the average assembly / disassembly time is reduced to 20 seconds, improving efficiency by 80% compared to traditional bolt fixing, while also offering higher locking reliability and preventing bolt loosening.

[0049] In some embodiments, the enclosure of the energy storage power supply unit 2 adopts a rigid-flexible composite structure, including an external metal frame and an internal engineering plastic insulating liner, which physically isolates the PMS compartment and the battery compartment; the PMS compartment and the battery compartment are arranged vertically orthogonally in space.

[0050] In this embodiment, the enclosure of the energy storage power supply unit 2 adopts a rigid-flexible composite structure. The exterior is a Q235 high-strength steel metal frame, which is treated with pickling, phosphating and electrostatic spraying for corrosion protection. It can withstand outdoor rain, dust and minor collisions, and will not deform or rust in environments ranging from -30℃ to 60℃. The rounded corner design prevents people from being scratched, and the side ventilation louvers take into account both heat dissipation and foreign object prevention.

[0051] The interior is made of flame-retardant ABS engineering plastic insulated liner with an insulation resistance value exceeding 100MΩ, which divides the interior of the cabinet into independent PMS compartment and battery compartment, blocking electrical interference—preventing the high-frequency electromagnetic signals of the power management system and inverter in the PMS compartment from affecting the charging and discharging efficiency of the energy storage battery in the battery compartment. At the same time, it isolates the trace gases generated by the charging and discharging of the battery compartment and discharges them through a dedicated exhaust channel to prevent them from coming into contact with electrical components and causing potential hazards.

[0052] The PMS compartment and battery compartment are arranged vertically orthogonally, making full use of the longitudinal space. This reduces the volume of the energy storage and power supply unit 2 by 30% compared to the traditional planar layout, making it suitable for the limited space of the mobile vehicle base 1. During maintenance, the internal equipment can be inspected by removing the top cover of the PMS compartment, and the battery can be replaced by pulling out the pull-out tray of the battery compartment, without the need for complete disassembly, reducing maintenance difficulty and time costs.

[0053] In some embodiments, the side wall of the PMS compartment is provided with a first heat dissipation hole group, and the bottom of the battery compartment is provided with a second heat dissipation hole group; the orifice orientation of the first heat dissipation hole group is perpendicular to the orifice orientation of the second heat dissipation hole group, forming two independent heat dissipation air ducts.

[0054] In this embodiment, the PMS cabin sidewall is provided with a first heat dissipation hole group (louvered type, opening to the side) to form a horizontal heat dissipation air duct. The power management module and inverter in the PMS cabin generate heat during operation, and hot air flows upward from the upper first heat dissipation hole group, while external cold air flows in from the lower hole group, forming continuous convection. The air flow velocity reaches 0.8m / s, and the cabin temperature is controlled within 45℃. The louvered structure prevents rainwater and sand from entering.

[0055] A second set of heat dissipation holes (a circular array with openings facing downwards) is located at the bottom of the battery compartment. This, together with a bottom cooling fan, forms a vertical heat dissipation airflow. The fan draws in cool external air through the second set of heat dissipation holes, directs it upwards through the gaps between the battery packs to absorb heat, and then exhausts it from the top exhaust vent, achieving forced convection. The openings of the first and second sets of heat dissipation holes are perpendicular to each other, and the heat dissipation airflow of the two compartments is completely independent, preventing the mixing of hot air and ensuring the heat dissipation efficiency of each compartment.

[0056] In high-temperature environments, the internal temperature of traditional non-partitioned heat dissipation enclosures exceeds 60°C, resulting in a 20% decrease in battery capacity and a 10% decrease in inverter efficiency. In this design, the PMS compartment temperature is only 42°C, the battery compartment temperature is 38°C, the battery capacity decreases by less than 5%, and the inverter efficiency remains above 95%, improving the system's high-temperature adaptability and stability.

[0057] In some embodiments, the heat dissipation fins of the PMS in-cabin converter are parallel to the air outlet direction of the first heat dissipation hole group.

[0058] In this embodiment, the heat dissipation fins of the PMS cabin converter are parallel to the air outlet direction of the first heat dissipation hole group, reducing airflow resistance and accelerating heat transfer. Traditional converter heat dissipation fins are perpendicular to the air outlet direction, resulting in high airflow resistance and low flow velocity (0.5m / s), limiting heat dissipation efficiency. In this design, the airflow moves along the length of the fins, increasing the flow velocity to 1.2m / s, significantly accelerating heat transfer.

[0059] The heat sink fins feature a comb-like structure with a 2mm spacing, balancing a heat dissipation area of ​​0.5㎡ with the need to prevent dust blockage. Anodizing treatment on the surface forms a dense oxide film, increasing the thermal conductivity from 200W / (m・K) to 230W / (m・K) while also preventing oxidation and corrosion. The fins are integrally molded with the converter housing, reducing contact thermal resistance and allowing for rapid heat transfer from the device to the fins.

[0060] When the converter is operating at full load, the surface temperature is only 55℃, which is far lower than the maximum junction temperature of the IGBT (125℃). After 8 hours of continuous full-load operation, the temperature only rises to 58℃, avoiding the shutdown due to overheating and ensuring the continuous power supply capability of the energy storage power supply unit 2.

[0061] In some embodiments, a cable management subsystem is also included, comprising a cable winding mechanism and a lifting guide mechanism; the cable winding mechanism is driven by a servo motor for winding and unwinding the output cable; the lifting guide mechanism is used to guide the output cable from a height when it is raised.

[0062] In this embodiment, the cable management subsystem includes a servo motor-driven cable reeling mechanism and a lifting guide mechanism, solving the problems of messy, cumbersome cable handling, and easy wear in traditional cable maintenance. The cable reeling mechanism is installed on one side of the mobile vehicle base 1 and contains a high-precision servo motor, a tension sensor, and a cable reel. When laying the cable, the operator issues a command through the PMS cabin touch screen, and the motor drives the reel to rotate and lay the cable. The tension sensor monitors the tension in real time, and the motor stops when the tension exceeds the 50N threshold to prevent cable breakage. The laying length is adjustable from 0-50m and automatically stops when the preset value is reached.

[0063] When high-altitude maintenance is required (such as testing of high-altitude busbars in substations), the lifting guide mechanism is activated—an electric push rod drives the guide bracket to an adjustable height of 1-5m. The pulleys at the top of the bracket guide the cable to extend towards the high-altitude maintenance point, preventing the cable from dragging and abrading the ground or becoming entangled in the equipment. After maintenance, the touchscreen sends a cable reel command, and the motor drives the drum to rotate counterclockwise. A tension sensor ensures uniform reel tension, preventing cable deformation and tangling. The system has an IP54 waterproof rating, allowing operation in outdoor rainy weather. Cable reeling time is reduced from 15 minutes to 2 minutes, and the outer sheath wear rate is reduced by 90%, extending cable life.

[0064] In some embodiments, the lifting guide mechanism is a telescopic cantilever tower structure with an insulated pulley that can rotate horizontally at the top of the tower.

[0065] In this embodiment, the lifting guide mechanism is a telescopic cantilever tower structure composed of multiple aluminum alloy sleeves. It is driven by an electric push rod to extend and retract, with a maximum extension height of 5m and a minimum retracted height of 1.2m. After retraction, it fits snugly against the side of the mobile vehicle base 1, without occupying additional space. The aluminum alloy material is lightweight and high-strength; the cantilever tower weighs only 15kg. It remains stable when the mobile vehicle base 1 is tilted ≤15°, and the bottom bolt fixing connection strength reaches 1000N, resisting winds of ≤5 levels.

[0066] The tower top is equipped with a horizontally rotatable insulated pulley made of epoxy resin with an insulation resistance value ≥1000MΩ. This pulley blocks electrical conduction between the cable and the cantilever tower, preventing current from being conducted to the mobile carrier base 1 when the cable is energized, thus ensuring safety during high-altitude operations. The pulley has a diameter of 100mm and a groove depth of 20mm, is suitable for cables with a diameter of 5-15mm, prevents the cable from coming loose, and can rotate 360° horizontally.

[0067] When performing high-altitude maintenance (such as testing a 3m high transformer), the cantilever tower extends to a height of 3.5m, the pulley rotates to align with the maintenance point, and the cable winding mechanism releases the cable through the pulley to the maintenance point, avoiding friction between the cable and the transformer casing. When adjusting the maintenance position, only the pulley needs to be rotated to change the direction, without the need to readjust the height, making the operation convenient and safe.

[0068] In some embodiments, the photovoltaic supplement unit 3 is connected via a biaxial hinge, which is equipped with a stepless adjustment and locking mechanism.

[0069] In this embodiment, the photovoltaic supplement unit 3 is connected to the top of the mobile vehicle base 1 via a dual-axis hinge. The dual-axis hinge includes a longitudinal rotation axis (controlling the photovoltaic panel's vertical tilt from 0 to 90°) and a transverse rotation axis (controlling the left and right rotation from 0 to 180°), and is equipped with a stepless adjustment and locking mechanism.

[0070] Staff adjust the dual-axis hinges according to the solar altitude and azimuth angles—for example, at 9 a.m. in the Northern Hemisphere, the photovoltaic panels are tilted 30° vertically and rotated 45° horizontally to the east to ensure the surface is perpendicular to the sunlight; fine adjustments can be made in real time as the sun's position changes to maintain optimal light intake. The stepless adjustment mechanism uses a worm gear drive, ensuring smooth and jerky adjustment with an accuracy of 1°, improving solar energy utilization by 20% compared to traditional 15° stepped adjustment.

[0071] After adjustment, tighten the locking knob to secure it; the locking force reaches 200N, and the angle remains unchanged even in winds of force 6. During cloudy, rainy days or at night, fold the photovoltaic panels until they are parallel to the top of the mobile vehicle base 1 to reduce space occupation. The photovoltaic supplement unit 3 is linked to the PMS compartment; when the light intensity is below 10,000 lux, the PMS compartment automatically switches to battery compartment power supply to ensure uninterrupted power supply to the platform and improve the utilization rate of green energy.

[0072] In some embodiments, the platform is configured to be used as a stand-alone mobile emergency power source after the functional instrument module 4 is disassembled.

[0073] In this embodiment, the platform can be used immediately as an independent mobile emergency power source after the functional instrument module 4 is disassembled. In the event of a substation power outage caused by natural disasters such as earthquakes or rainstorms, or when power is needed for temporary work sites or emergency equipment, the staff can unlock the locking structure of the first quick-connect male and female connectors, remove all functional instrument modules 4, and retain only the mobile vehicle base 1, energy storage power supply unit 2, and photovoltaic supplement unit 3. The conversion can be completed in 5-10 minutes, which is faster than traditional emergency power vehicles (which require more than 30 minutes of preparation).

[0074] After conversion, the mobile vehicle base 1 is moved to the emergency point. When there is sufficient sunlight, the angle of the photovoltaic supplement unit 3 is adjusted, and the solar energy is converted into an adjustable voltage of AC220V / 380V or DC12V / 24V / 48V via the PMS compartment. When there is insufficient sunlight or at night, the battery compartment is used directly for power supply. The PMS compartment monitors the battery level and load power consumption in real time, and issues a low battery alarm when the battery level is below 20%. The output cable is released through a cable reeling mechanism. The high-altitude emergency equipment can use a lifting guide mechanism to guide the cable. The power supply capacity reaches 5kW, and it can provide continuous power for 8 hours when fully charged, meeting the needs of small and medium-sized emergency scenarios. It can be used for both maintenance and emergency purposes, improving equipment utilization and reducing procurement costs.

[0075] Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the devices, apparatuses, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here.

[0076] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
