Description

Technical Field

[0001] This invention relates to the field of integrated cabinet technology, and in particular to a smart integrated cabinet for photovoltaic, energy storage and diesel fuel. Background Technology

[0002] With the rapid development of integrated energy systems, photovoltaic-storage-diesel integrated power supply equipment, leveraging the complementary advantages of clean and energy-saving photovoltaic power generation, peak shaving and valley filling by energy storage systems, and emergency backup by diesel generators, is widely used in scenarios such as field base stations, remote mining areas, villages without power grids, and emergency power supply projects. The photovoltaic-storage-diesel intelligent integrated cabinet integrates photovoltaic, energy storage, diesel power generation, power distribution, and intelligent control systems into one unit, serving as a core device for ensuring stable grid connection, off-grid switching, and intelligent dispatching of multiple energy sources.

[0003] Currently, traditional integrated photovoltaic-storage-diesel cabinets have a relatively simple structural design, poor integration and layout of functional units, and limited, fixed heat dissipation and moisture-proof functions, making them unsuitable for complex outdoor weather conditions. Conventional cabinets only have fixed ventilation openings for routine ventilation, which provides basic heat dissipation in dry, sunny environments. However, in rainy, foggy, or high-humidity weather, humid air continuously enters the cabinet through these openings. The internal energy storage batteries, power distribution modules, and intelligent control circuit boards are extremely sensitive to humidity. Prolonged exposure to high humidity can easily lead to component oxidation, reduced insulation, circuit leakage, short circuits, and accelerated battery degradation, severely impacting the power supply stability and lifespan of the entire system. Therefore, a smart integrated photovoltaic-storage-diesel cabinet is needed to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent integrated cabinet for photovoltaic, energy storage, and diesel fuel to solve the above-mentioned problems.

[0005] The above-mentioned technical objective of this invention is achieved through the following technical solution: a smart integrated cabinet for photovoltaic, energy storage, and diesel fuel, comprising:

[0006] The cabinet contains a photovoltaic unit installation area, an energy storage unit installation area, a diesel generator unit installation area, a power distribution unit installation area, and a control unit installation area.

[0007] The cabinet is equipped with a moisture-proof mechanism;

[0008] The moisture-proof mechanism includes a side shell, a perforated plate, a partition, an electric telescopic rod, a pusher, and a sealing plate;

[0009] The side shell is fixedly installed on the cabinet body, the perforated plate is fixedly installed on the cabinet body, the partition is fixedly installed inside the side shell, ventilation holes are provided on both the side shell and the cabinet body, the sealing plate seals the ventilation holes, the electric telescopic rod is fixedly installed on the bottom inner wall of the side shell, the output end of the electric telescopic rod is fixedly connected to the push frame, and the side of the push frame is fixedly connected to the sealing plate.

[0010] A further configuration of the present invention is as follows: the moisture-proof mechanism further includes a connecting frame, a sealing plate, a drying box, a vertical frame, a rotating shaft, a rubber striking element, a gear, a synchronizing frame, a toothed plate, and an air pump. The connecting frame is fixedly installed on the sealing plate, and the bottom of the connecting frame is fixedly connected to the sealing plate. The drying box is fixedly installed inside the side shell and is fixedly connected to the partition. The vertical frame is fixedly installed on the top of the partition. The rotating shaft is rotatably installed on the vertical frame. The rubber striking element is fixedly installed on the rotating shaft. The gear is fixedly sleeved on the outside of the rotating shaft. The toothed plate is fixedly installed on the synchronizing frame, and the synchronizing frame is fixedly installed on the push frame. The gear meshes with the toothed plate. The air pump is fixedly installed on the top of the cabinet.

[0011] A further feature of the present invention is that a sealing hole is provided on the top of the side shell, and the sealing plate is adapted to the sealing hole.

[0012] A further feature of the present invention is that an air inlet is provided at the bottom of the side shell.

[0013] A further feature of the present invention is that a canopy is fixedly provided on the top of the cabinet.

[0014] A further feature of the present invention is that a rain sensor is fixedly installed on the back of the cabinet.

[0015] A further feature of the present invention is that a square hole is provided at the top of the side shell, and the sealing plate is slidably installed in the square hole.

[0016] A further configuration of the present invention is that the rubber striking element is located above the drying box.

[0017] The beneficial effects of this invention are:

[0018] 1. This invention features a moisture-proof mechanism that automatically switches between ventilation and heat dissipation and closed dehumidification modes based on rainy or sunny weather conditions. It is highly functional. In sunny weather, the ventilation channel is automatically opened, and natural convection is used to achieve rapid heat dissipation of the cabinet. At the same time, the airflow can carry away the moisture adsorbed in the drying box, enabling the desiccant to regenerate autonomously without frequent replacement of consumables, resulting in low maintenance costs. In rainy weather, the electric telescopic rod links the sealing plate and the sealing plate to completely seal the ventilation channel of the cabinet, preventing the intrusion of external moisture.

[0019] 2. This invention utilizes a moisture-proof mechanism that employs a toothed plate and gear meshing to drive a rubber striking component to strike the drying box, causing the desiccant to vibrate, loosen, and fully release moisture. Combined with a vacuum pump for negative pressure dehumidification and air intake drying circulation, the humidity inside the cabinet is continuously reduced, effectively preventing energy storage batteries, power distribution components, and control modules from becoming damp and oxidized, reducing insulation, and causing short circuits. This significantly improves the safety, stability, and service life of the equipment during outdoor operation. Attached Figure Description

[0033] See Figures 1-6 This invention provides a smart integrated cabinet for photovoltaic, energy storage, and diesel fuel, comprising:

[0034] Cabinet 1, which contains photovoltaic unit installation area 2, energy storage unit installation area 3, diesel generator unit installation area 4, power distribution unit installation area 5, and control unit installation area 6;

[0035] Cabinet 1 is equipped with a moisture-proof mechanism;

[0036] The moisture-proof mechanism includes a side shell 7, a mesh plate 8, a partition 9, an electric telescopic rod 10, a pusher 11, and a sealing plate 12;

[0037] The side shell 7 is fixedly installed on the cabinet 1, the perforated plate 8 is fixedly installed on the cabinet 1, the partition 9 is fixedly installed inside the side shell 7, and ventilation holes are provided on both the side shell 7 and the cabinet 1. The sealing plate 12 seals the ventilation holes. The electric telescopic rod 10 is fixedly installed on the bottom inner wall of the side shell 7. The output end of the electric telescopic rod 10 is fixedly connected to the push frame 11, and the side of the push frame 11 is fixedly connected to the sealing plate 12.

[0038] With the above structure, under normal weather conditions, the cabinet 1 is ventilated and dissipated through the mesh plates 8 on both sides. At this time, the air inside the side shell 7 circulates, removing moisture from the drying particles in the drying box 15. When the rain sensor detects rain, it can start the electric telescopic rod 10 through the controller inside the cabinet 1. The electric telescopic rod 10 drives the push frame 11 to move, and the push frame 11 drives the sealing plate 12 to move, exposing the ventilation holes. The sealing plate 12 seals the mesh plate 8. The cabinet 1 is equipped with a cabinet door on the front side during actual use.

[0039] The intelligent control unit acquires photovoltaic (PV) output and load demand data through a prediction module. It prioritizes PV unit power generation. When PV output meets load demand, excess energy is transmitted to the grid via the PCS bidirectional converter or stored in the energy storage unit. When PV output is insufficient, the grid supplements power, and the energy storage unit performs charging and discharging scheduling based on peak-valley electricity prices to achieve peak-valley arbitrage. The diesel generator is in standby mode; it starts immediately upon grid failure, achieving seamless switching. The intelligent control unit prioritizes PV unit power generation, storing excess energy in the energy storage unit when PV output meets load demand. When PV output is insufficient, the energy storage unit discharges to supplement power. When the energy storage SOC falls below 10%, the intelligent control unit starts the diesel generator, which operates in its high-efficiency load range, supplying power to the load while charging the energy storage unit until the energy storage SOC reaches 90%, at which point the diesel generator shuts down and goes into standby mode. During sudden load changes, the intelligent control unit quickly adjusts power distribution to ensure voltage and frequency stability. When power is restored to the grid, the intelligent control unit controls the ATS / STS switching, switching the power supply from the diesel generator to the grid. Simultaneously, it controls the PCS bidirectional converter to switch from V / F mode to PQ mode, achieving seamless switching. When the grid fails again, it quickly switches to off-grid mode, with photovoltaic, energy storage, and diesel generators working together to provide power, with no power outage gaps during the switching process. The operation and maintenance management unit collects real-time operating data from each unit, performs fault diagnosis and early warning through the edge computing module, and pushes fault information to the operation and maintenance platform. Maintenance personnel can remotely locate faults and perform maintenance. The safety protection unit monitors the system's safety status in real time. When an anomaly occurs, it immediately issues an early warning signal and takes protective measures to prevent the fault from escalating.

[0040] The system integrates photovoltaic, energy storage, diesel generator, power distribution, and intelligent control modules, reducing on-site wiring and debugging workload and shortening the deployment cycle by more than 30%. It also achieves unified compatibility of communication protocols among various devices, reducing the difficulty of joint debugging and improving the stability of system collaborative operation. Through integrated thermal design, electromagnetic compatibility, and safety protection design, the equipment can adapt to complex environments such as high temperature, low temperature, and high humidity, improving the reliability of equipment operation.

[0041] Specifically, the moisture-proof mechanism also includes a connecting frame 13, a sealing plate 14, a drying box 15, a vertical frame 16, a rotating shaft 17, a rubber striking element 18, a gear 19, a synchronizing frame 20, a toothed plate 21, and an air pump 23. The connecting frame 13 is fixedly installed on the sealing plate 12, and the bottom of the connecting frame 13 is fixedly connected to the sealing plate 14. The drying box 15 is fixedly installed inside the side shell 7 and is fixedly connected to the partition 9. The vertical frame 16 is fixedly installed on the top of the partition 9. The rotating shaft 17 is rotatably installed on the vertical frame 16. The rubber striking element 18 is fixedly installed on the rotating shaft 17. The gear 19 is fixedly sleeved on the outside of the rotating shaft 17. The toothed plate 21 is fixedly installed on the synchronizing frame 20. The synchronizing frame 20 is fixedly installed on the push frame 11. The gear 19 meshes with the toothed plate 21. The air pump 23 is fixedly installed on the top of the cabinet 1.

[0042] With the above structure, during the upward movement of the sealing plate 12, the connecting frame 13 and the sealing plate 14 move upward synchronously. The sealing plate 14 seals the sealing hole, and the push frame 11 drives the synchronous frame 20 to move. The synchronous frame 20 drives the toothed plate 21 to move. The toothed plate 21 drives the gear 19 to rotate. The gear 19 drives the rotating shaft 17 to rotate. The rotating shaft 17 drives the rubber striking part 18 to rotate. The rubber striking part 18 strikes the drying box 15, causing the drying particles inside the drying box 15 to vibrate and allowing the moisture in the drying particles to be quickly discharged. Subsequently, the air pump 23 is started, allowing outside air to enter through the air inlet 22. The drying box 15 dries the outside air, which then enters through the ventilation hole. This effectively prevents moisture inside the cabinet 1 during rainy days.

[0043] Specifically, a sealing hole is provided at the top of the side shell 7, and the sealing plate 14 is adapted to the sealing hole. An air inlet 22 is provided at the bottom of the side shell 7.

[0044] The above structure facilitates the subsequent sealing of the sealing holes by the sealing plate 14.

[0045] Specifically, a canopy is fixedly installed on the top of cabinet 1, and a rain sensor is fixedly installed on the back of cabinet 1.

[0046] With the above structure, when the rain sensor detects rain, it can activate the electric telescopic rod 10 through the controller inside the cabinet 1.

[0047] Specifically, a square hole is provided at the top of the side shell 7, the sealing plate 12 is slidably installed in the square hole, and the rubber striking part 18 is located above the drying box 15.

[0048] With the above structure, the rubber striking element 18 can strike the drying box 15, causing the dried particles inside the drying box 15 to vibrate.

[0049] Working principle:

[0050] The cabinet 1 is internally divided into independent photovoltaic unit installation area 2, energy storage unit installation area 3, diesel generator unit installation area 4, power distribution unit installation area 5, and control unit installation area 6, realizing the integrated assembly of photovoltaic, energy storage, diesel generator, power distribution, and intelligent control equipment. The control unit realizes multi-source coordinated scheduling based on photovoltaic output, load power, grid on / off status, and energy storage capacity: photovoltaic power supply is prioritized on sunny days, and surplus energy is stored in the energy storage unit; when photovoltaic output is insufficient, energy storage discharges to supplement energy; when the energy storage capacity is lower than the threshold or the grid is interrupted, the diesel generator is automatically started to provide backup power supply, and seamless grid connection is achieved after the grid is restored. The entire power supply system can automatically complete power distribution, grid-connected / off-grid switching, peak-valley energy storage arbitrage, and fault early warning.

[0051] The moisture-proof mechanism of cabinet 1 is automatically controlled by a rain sensor-linked controller, with two working modes: ventilation and heat dissipation in sunny weather and closed dehumidification in rainy weather. When there is no rain, the electric telescopic rod 10 is in the retracted state, and the pusher 11 moves the sealing plate 12 down, so that the ventilation holes on the side shell 7 and cabinet 1 are fully open, and the mesh plates 8 on both sides of cabinet 1 remain open. Ambient air enters through the air inlet 22 at the bottom of the side shell 7, passes through the partition 9 and the drying box 15, and flows into the cabinet through the ventilation holes. The whole machine is cooled by natural convection, and the flowing air simultaneously carries away the moisture adsorbed by the desiccant in the drying box 15, realizing the self-regeneration of the desiccant. At this time, the sealing plate 14 moves down with the sealing plate 12, the sealing hole at the top of the side shell 7 remains open, and the air inside the side shell 7 circulates smoothly. The toothed plate 21 moves down with the synchronous frame 20, and the gear 19 and the rotating shaft 17 drive the rubber striking part 18 away from the drying box 15, without any striking action.

[0052] After the rain sensor detects a rain signal, the controller drives the electric telescopic rod 10 to extend, pushing the pusher 11 to slide upwards. The pusher 11 drives the sealing plate 12 to move upwards along the square hole of the side shell 7, completely sealing the ventilation hole of the cabinet 1 and the mesh plate 8, preventing outdoor humid rain and high humidity air from entering the cabinet and preventing the photovoltaic, energy storage, and power distribution electrical components from getting damp and short-circuiting. The sealing plate 12 simultaneously drives the connecting frame 13 and the sealing plate 14 to move upwards, and the sealing plate 14 engages to seal the sealing hole at the top of the side shell 7, making the side shell 7 a sealed chamber. The pusher 11 drives the synchronous frame 20 and the toothed plate 21 to move upwards simultaneously, and the toothed plate 21 engages to drive the connection. Gear 19 rotates, and shaft 17 drives rubber striking part 18 to swing back and forth, continuously striking the drying box 15, causing the desiccant particles inside the box to vibrate and loosen, releasing the water vapor adsorbed inside; the top air pump 23 of cabinet 1 is started, and the air pump draws out the humid air inside the cabinet. Dry air from the outside can only enter from the bottom air inlet 22 of the side shell 7 in one direction. The air passes through the drying box 15 to complete deep dehumidification before being sent into the cabinet 1. In a closed environment, the humidity inside the cabinet is continuously reduced, preventing the energy storage battery, power distribution components, and control module from being damp and corroded, and the insulation from deteriorating, thus ensuring the stable operation of the photovoltaic-storage-diesel integrated equipment in rainy weather.

[0053] After the rain stops, the rain sensor signal disappears, the electric telescopic rod 10 automatically retracts, the moisture-proof mechanism resets to ventilation mode, and the whole machine resumes natural heat dissipation and desiccant regeneration cycle.
