Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment, specifically to an outdoor wind, solar and diesel integrated energy storage machine. Background Technology

[0002] Both wind power and photovoltaic power generation are clean and reliable power generation methods. However, due to natural conditions, neither can achieve continuous and stable power generation. Therefore, existing outdoor power generation systems have incorporated diesel generators to compensate for the shortcomings of wind power and photovoltaic power generation.

[0003] For example, Chinese patent document CN117498763A, entitled "A Conveniently Portable Wind-Solar-Diesel-Storage Integrated Multi-Energy Complementary Power Generation System", discloses a power generation system that integrates wind power, photovoltaic power and diesel power generation. However, in this system, the AC distribution box, DC distribution box, photovoltaic-storage integrated unit, energy storage unit and various monitoring units are all scattered inside the box, resulting in a large overall box size, large footprint, and inconvenience in transportation and installation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an outdoor integrated wind, solar, and diesel energy storage unit that is compact in structure, small in size, and easy to transport and install.

[0005] The technical solution adopted by this utility model to solve the problem is:

[0006] An outdoor wind-solar-diesel integrated energy storage unit includes a cabinet, a hybrid inverter, a DC control box, and an energy storage battery. The hybrid inverter, DC control box, and energy storage battery are all located inside the cabinet and are adjacent to each other. The cabinet is equipped with a liquid cooling component located below the energy storage battery for heat dissipation. Each panel of the cabinet is close to its adjacent components, and the front and rear panels close to the hybrid inverter are provided with first mesh holes for ventilation and heat dissipation of the hybrid inverter.

[0007] Furthermore, the cabinet contains an AC combiner box located immediately below the liquid cooling assembly, and second mesh openings are provided on the front and rear panels close to the AC combiner box for ventilation and heat dissipation.

[0008] Furthermore, the cabinet is provided with a vertical partition that divides the internal space of the cabinet into a left compartment and a right compartment. The left compartment is provided with a horizontal partition that divides the left compartment into two installation positions, and the right compartment is provided with two horizontal partitions that divide the right compartment into three installation positions, namely, upper, middle and lower. The hybrid inverter and the DC control box are fixedly connected to the two installation positions in the left compartment from top to bottom, and the energy storage battery, liquid cooling component and AC combiner box are fixedly connected to the three installation positions in the right compartment from top to bottom.

[0009] Furthermore, the front and rear panels of the cabinet are each composed of an openable and closable first cabinet door and a second cabinet door, and the first and second cabinet doors can respectively cover the left and right compartments. The panel on the left side of the cabinet is composed of an openable and closable third cabinet door, which can cover the side of the left compartment.

[0010] Furthermore, the inner sides of the first, second, and third cabinet doors are all provided with fireproof and heat-insulating layers, and the second cabinet door at the rear is also provided with an explosion-proof valve.

[0011] Furthermore, a transformer capable of changing the voltage of the output current is also provided in the mounting position below the left compartment.

[0012] Furthermore, the cabinet is equipped with a dehumidifier for dehumidifying when the humidity inside the cabinet exceeds a threshold.

[0013] Furthermore, the right compartment is equipped with a fire extinguishing device for extinguishing fires when the temperature and smoke levels inside the cabinet exceed a corresponding threshold.

[0014] Furthermore, a water immersion transmitter is installed at the mounting position below the left compartment, and limit switches are installed at the first, second, and third cabinet doors of the cabinet.

[0015] Furthermore, the cabinet is also equipped with a load circuit breaker and a grid circuit breaker that disconnect the circuit when the load current and grid current exceed their respective rated values.

[0016] The beneficial effects of this utility model are as follows: This utility model arranges the hybrid inverter, DC control box and energy storage battery in close proximity within the cabinet, and provides a liquid cooling component to dissipate heat from the energy storage battery. At the same time, first mesh holes for ventilation and heat dissipation of the hybrid inverter are provided on both the front and rear panels.

[0021] The following will provide a clear and complete description of the concept, specific structure, and technical effects of this invention in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this invention. The various technical features of this invention can be combined interactively without contradicting each other.

[0022] Reference Figures 1 to 4 An outdoor wind-solar-diesel integrated energy storage unit includes a cabinet 1, a hybrid inverter 2, a DC control box 3, an energy storage battery 4, and a liquid cooling component 5. The hybrid inverter 2, DC control box 3, energy storage battery 4, and liquid cooling component 5 are arranged closely together inside the cabinet 1, with the liquid cooling component 5 located below the energy storage battery 4 for heat dissipation of the battery pack. Each panel of the cabinet 1 is close to its adjacent components, making the entire cabinet 1 more compact and smaller in size. In addition, the front and rear panels of the cabinet 1 close to the hybrid inverter 2 are provided with first mesh holes 111 for ventilation and heat dissipation of the hybrid inverter 2.

[0023] In an implementation, such as Figure 2 and Figure 4 As shown, the cabinet 1 has a vertical partition that divides the internal space of the cabinet 1 into a left compartment and a right compartment; the left compartment has a horizontal partition that divides the space of the left compartment into upper and lower installation positions; the right compartment has two horizontal partitions that divide the space of the right compartment into upper, middle and lower installation positions.

[0024] In the above structure, the hybrid inverter 2 and DC control box 3 are fixedly connected from top to bottom to two mounting positions in the left compartment, while the energy storage battery 4 and liquid cooling assembly 5 are fixedly connected from top to bottom to two mounting positions in the upper middle of the right compartment. Additionally, an AC combiner box 6 is installed at the lowest mounting position in the right compartment. When multiple integrated units need to be connected in parallel to increase the output load power, the AC combiner box 6 collects the current and manages it in a unified manner. Second mesh openings are provided on the front and rear panels near the AC combiner box 6 for ventilation and heat dissipation.

[0025] In an implementation, such as Figure 2 and Figure 4As shown, the front and rear panels of the cabinet 1 are each composed of an openable and closable first cabinet door 11 and a second cabinet door 12, which can respectively cover the left and right compartments. The left panel of the cabinet 1 is composed of an openable and closable third cabinet door 13, which can cover the side of the left compartment. The first, second, and third cabinet doors 11, 12, and 13 facilitate the installation, maintenance, and replacement of various components. To reduce internal and external heat conduction, fireproof and heat-insulating layers, such as aluminum foil insulation cotton, are provided on the inner surfaces of the first, second, and third cabinet doors 11 and 13. An explosion-proof valve 10 is also installed on the rear second cabinet door 12. When the internal pressure of the integrated machine exceeds a preset threshold, the explosion-proof valve 10 automatically opens through a mechanical structure to quickly release the pressure and prevent the system from exploding due to excessive internal pressure.

[0026] In one embodiment, such as Figure 1 As shown, the second cabinet door 12 at the front is equipped with an emergency stop button switch 20, a 4G antenna module 30, a running indicator light 40, and a fault indicator light 50. The 4G antenna module 30 amplifies signal strength, expands coverage, and reduces signal attenuation and interference. When the device is started and running normally, the running indicator light 40 is constantly lit, displaying the current operating status of the system and helping users quickly determine if the all-in-one machine is working properly. When a malfunction occurs, the fault indicator light 50 is constantly lit, indicating an abnormality or fault in the system, helping users quickly locate the problem. In hazardous scenarios, pressing the emergency stop button switch 20 cuts off the power to the all-in-one machine, forcibly stopping all operating components. This prevents operator injury and reduces secondary damage.

[0027] The hybrid inverter 2 in this integrated unit is a bidirectional hybrid inverter 2, internally containing wind, solar, and diesel inverters. It serves as the "intelligent hub" of the hybrid energy system, achieving stable, efficient, and sustainable power supply through power conversion, multi-source coordination, and energy storage management. The hybrid inverter 2 outputs voltage conforming to the local voltage; if installed abroad, it outputs the foreign voltage. If conversion to another voltage is required, transformer 7 is installed to transform the output current. Figure 2 As shown, transformer 7 is installed behind DC control box 3 in the mounting position below the left compartment.

[0028] The integrated unit's energy storage battery 4 employs three sets of high-energy, high-density energy storage battery packs. These battery packs utilize a modular structure, with each pack individually packaged and equipped with a BMS (Battery Management System). This design effectively blocks thermal runaway propagation, prevents chain reactions, and allows for partial replacement rather than complete scrapping in case of failure, significantly reducing financial burden. Each module is equipped with an independent liquid cooling pipe 52, enhancing its heat dissipation efficiency. The number of battery packs can be adjusted according to actual needs. The liquid cooling assembly 5 includes a liquid cooling unit 51 and multiple liquid cooling pipes 52, the same number as the battery packs. These pipes 52 circulate cooling to each battery pack, further improving heat dissipation efficiency. The liquid cooling unit 51 utilizes the high specific heat capacity and thermal conductivity of the liquid medium to rapidly absorb and transfer heat, preventing battery overheating, avoiding the risk of thermal runaway, and ensuring uniform internal battery temperature, thus slowing down battery aging and extending overall lifespan. In addition, a transformer exhaust fan 100 and an inverter exhaust fan 200 can be installed inside the cabinet 1 to provide air cooling for the transformer 7 and the hybrid inverter 2, respectively.

[0029] The DC control box 3 of this all-in-one unit contains EMS, BMS, control components, etc., and is the brain of energy storage battery 4. Through precise control, safety protection and efficient management, it ensures safe, stable and efficient operation between the battery and DC side equipment, while extending battery life and improving the overall economic efficiency of the system.

[0030] To further improve the safety of this all-in-one machine's operation, such as Figure 2 and Figure 4 As shown, a dehumidifier 60 and a fire extinguishing device 70 are installed inside cabinet 1. The dehumidifier 60 is located at the second cabinet door 12, and the fire extinguishing device 70 is an aerosol fire extinguisher installed at the top of the right compartment. A temperature and humidity sensor 80 detects the humidity and temperature inside the cabinet. When these exceed corresponding thresholds, the dehumidifier 60 and the fire extinguishing device 70 respectively dehumidify and extinguish the fire. Additionally, a water immersion transmitter 8 is installed at the lower mounting position of the left compartment. Limit switches 90 are installed at the first cabinet door 11, the second cabinet door 12, and the third cabinet door 13. A wireless transmission module, including an RS485 module and an EMS cloud platform system, is also installed inside cabinet 1. In the event of water immersion, the water immersion transmitter 8 will trigger an audible and visual alarm on cabinet 1. Simultaneously, the trigger signal will notify the management platform via the RS485 module, allowing the platform to stop the equipment and prevent accidents. If the cabinet door is illegally opened, the limit switch 90 will be triggered, and the trigger signal will be fed back to the EMS cloud platform. In this way, the cloud platform can monitor in real time whether the cabinet door is in the closed state.

[0031] To improve the electrical safety of the all-in-one machine during operation, such as Figure 2 and Figure 4As shown, the cabinet 1 also includes a load circuit breaker 300 and a grid-connected circuit breaker 400. The load circuit breaker 300 automatically disconnects the circuit when the load current exceeds the rated value, while the grid-connected circuit breaker 400 automatically disconnects the circuit when multiple integrated units are connected to the grid and the grid-connected current exceeds the corresponding rated value. The bimetallic strip inside the circuit breaker may bend due to heat, triggering the tripping mechanism to trip and cut off the power supply, preventing overheating of the wires from causing a fire or equipment damage. Alternatively, in the event of a short circuit, the current may surge instantaneously to thousands of amperes; the circuit breaker will respond quickly through the electromagnetic tripping device to cut off the circuit, preventing equipment damage or arcing accidents.
