Description

Technical Field

[0001] This utility model belongs to the field of new energy technology, specifically relating to a multifunctional solar power generation and energy storage device. Background Technology

[0002] Multifunctional solar power generation and energy storage equipment has become a core supporting equipment in the new energy field in recent years. It uses an energy storage battery box as the core of electrical energy storage, and is equipped with an inverter control top box to realize the conversion of electrical energy. It also integrates auxiliary functions such as rotatable lighting, convenient touch operation, and efficient heat dissipation. It can store the electrical energy converted by solar energy and supply it to outdoor operations, home emergency, small commercial scenarios, etc. without relying on the power grid to achieve local power supply, which greatly improves the flexibility and practicality of solar energy utilization and has become an important part of distributed energy systems.

[0003] However, existing multi-functional solar power generation and energy storage equipment has a fire risk in its core components (energy storage battery and inverter control module) during operation. The energy storage battery is prone to thermal runaway due to long-term charging and discharging. Short circuits in the inverter control top box may cause electric arc fires. Existing equipment mostly relies on manual inspection to detect fires or is only equipped with simple temperature alarm devices, lacking active fire extinguishing capabilities. Once a fire occurs, the response time for manual fire extinguishing is long, and the fire can easily spread to the energy storage battery box, causing the entire equipment to burn down and even causing fires in the surrounding area.

[0009] Preferably, the active emergency fire-fighting device further includes a rectangular hollow air distribution plate, a blower head, a delivery pipe, and a solenoid valve B. The solenoid valve B is sealed and fixed at the center of the bottom end of the hollow storage box. The delivery pipe is connected to the bottom outlet of the solenoid valve B. The rectangular hollow air distribution plate is sealed and connected to the bottom end of the delivery pipe. Multiple blower heads are equidistantly arranged at the bottom end of the rectangular hollow air distribution plate.

[0010] Preferably, the active emergency fire-fighting device further includes a self-contained battery box. A recessed battery box storage slot is provided at the center of the rear end of the hollow storage box. The self-contained battery box is fixed in the battery box storage slot. The self-contained battery box is electrically connected to the inverter control top box, solenoid valve A, and solenoid valve B respectively via wires.

[0011] Preferably, the rectangular hollow air distribution plate is attached and fixed to the top outer wall of the inverter control top box, and the bottom ends of the plurality of blow nozzles are inserted into and penetrate the top outer wall of the inverter control top box, and the plurality of blow nozzles are connected to the interior of the inverter control top box.

[0012] Preferably, the front end of the energy storage battery box is open, and a detachable box plate A is fixed to the front end of the energy storage battery box by multiple embedded screws.

[0015] Compared with the prior art, this utility model provides a multifunctional solar power generation and energy storage device, which has the following beneficial effects:

[0016] This invention adds a novel active emergency fire suppression device to the top of the inverter control top box. This device can actively trigger fire suppression when a fire hazard or initial fire occurs inside the solar power storage equipment, quickly suppressing the spread of fire and preventing thermal runaway of the storage battery or circuit burnout. It also has the advantages of independent power supply and uniform fire suppression, providing key protection for the safe operation of the equipment. The active emergency fire suppression device relies on its own backup power supply and solenoid valve control to achieve active response. The backup battery box at the rear of the empty storage tank is electrically connected to the inverter control top box, solenoid valve A, and solenoid valve B via wires. When the inverter control top box detects abnormal internal temperature or a fire signal, it will immediately send a trigger command to solenoid valve A and solenoid valve B. If the inverter control top box is unable to send a command due to a malfunction, the backup battery box can serve as an independent power supply unit to ensure that the solenoid valves can still be activated normally. This dual-trigger and independent power supply design avoids the delay problems of traditional manual fire extinguishing or reliance on external power supply. The response time from fire detection to the start of fire extinguishing action can be greatly shortened. It can quickly intervene before the fire spreads to the energy storage battery or core circuit and control the fire in the early stage.

[0017] The core of the active emergency fire suppression system relies on the synergy of high-pressure gas cylinders and fire extinguishing dry powder. The high-pressure gas cylinder in the hollow storage tank is connected to the fire extinguishing dry powder inside the tank via solenoid valve A. When solenoid valve A is opened, high-pressure gas rushes into the hollow storage tank, creating a high-pressure drive for the fire extinguishing dry powder. Subsequently, solenoid valve B is opened, and the fire extinguishing dry powder enters the rectangular hollow air distribution plate through the delivery pipe, and then is sprayed into the interior of the inverter control top box through multiple spray nozzles. The high-pressure drive design allows the fire extinguishing dry powder to spread evenly at a high speed, covering the circuit components inside the inverter control top box. At the same time, the spray nozzles penetrate through the inverter control top box and connect to the energy storage battery box, allowing some dry powder to penetrate downwards into the energy storage battery box to suppress potential thermal runaway fires in the energy storage battery. The fire extinguishing dry powder used is ABC type, which can effectively extinguish electrical fires and will not cause secondary corrosion to the metal components and circuits inside the equipment.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figure 1-6 This is a multifunctional solar power generation and storage device. This device can store, convert, and safely use solar energy. It is also equipped with an active emergency fire-fighting device 6, suitable for outdoor, residential, and other power supply needs. The energy storage battery box 10 is the core energy storage component, containing multiple energy storage batteries as the carriers of electrical energy. These batteries are electrically connected to the inverter control top box 5. The inverter control top box 5 converts the energy storage batteries into charging and discharging power. When the solar panel (connected via junction box 11) generates electricity, the inverter control top box 5 rectifies the electricity and sends it to the energy storage batteries for storage. When power is needed, the inverter control top box 5 inverts the DC power from the energy storage batteries into AC power to supply power to external devices. The energy storage battery box 10 is located at the front... The end features an open design, with a removable panel A2 secured by multiple embedded screws. The embedded screw design prevents protruding screws from scratching personnel or other equipment. The removable structure facilitates future maintenance and replacement of the energy storage battery (e.g., in case of a single battery failure, the entire enclosure can be removed without disassembling the battery; only the removable panel A2 needs to be removed), reducing maintenance complexity. The bottom of the energy storage battery box 10 is equipped with an insulated mounting base 1, allowing the equipment to be placed directly on the ground. The insulated mounting base 1 is made of high-strength insulating material (epoxy resin board), preventing ground moisture and stray current from contacting the energy storage battery box 10, avoiding the risk of leakage due to poor grounding. It also provides stable support for the energy storage battery box 10, preventing corrosion caused by direct contact between the bottom of the box and the ground.

[0027] like Figure 1 , Figure 2 and Figure 3As shown, the inverter control top box 5 is located at the top of the energy storage battery box 10 and is connected to the interior of the energy storage battery box 10. As the control core of the device, its front end is open, and a removable panel B3 is fixed to it by multiple embedded screws. The design of the removable panel B3 is consistent with the principle of the removable panel A2 of the energy storage battery box 10, facilitating the maintenance of the inverter, controller, and other components inside the inverter control top box 5. A touch screen 4 is installed inside the center of the front end of the removable panel B3. Users can intuitively view the device status (such as energy storage battery power, output voltage, and temperature) and set parameters (such as charging current and discharge protection threshold) through the touch screen 4. Operation is possible without connecting external devices, improving ease of use. A junction box 11 is fixed at the center of the rear outer wall of the inverter control top box 5. The junction box 11 serves as a connection interface for external devices, allowing connection to solar panels (for charging), external loads (such as... This device is designed for use with home appliances and lighting fixtures. It also features internal overload and short-circuit protection modules. When external equipment malfunctions, the junction box 11 can quickly cut off the circuit, protecting the inverter control top box 5 and the energy storage battery from damage, thus improving equipment safety. U-shaped lampshades 7 are fixed to the center of the outer walls at both ends of the inverter control top box 5. A rotatable lighting lamp 8 is connected to the opening of the U-shaped lampshade 7 via a rotating shaft. The rotatable lighting lamp 8 is electrically connected to the inverter control top box 5. The U-shaped lampshade 7 provides protection for the rotatable lighting lamp 8, preventing rain and dust from directly contacting the lamp body, while not obstructing light illumination. The rotatable lighting lamp 8 can rotate vertically via the rotating shaft, allowing users to adjust the lighting angle as needed (e.g., illuminating the ground around the equipment downwards, or providing auxiliary lighting upwards). This adapts to scenarios such as nighttime equipment maintenance and temporary lighting. Furthermore, the power is provided by the device itself, eliminating the need for an external power source, thus enhancing its practicality.

[0028] like Figure 1 , Figure 2 and Figure 3As shown, multiple air inlets 9 are equidistantly arranged on the inner walls of the left and right ends of the energy storage battery box 10. A rectangular heat dissipation window is provided at the center of the rear end. A heat dissipation casing 12 that completely covers the rectangular heat dissipation window is fixed to the outer wall of the rear end, and the heat dissipation casing 12 is electrically connected to the inverter control top box 5. This side air intake and rear air exhaust heat dissipation design forms a directional airflow channel. When the heat dissipation casing 12 is working, the internal fan generates negative pressure, and external cold air enters the energy storage battery box 10 through the air inlets 9 at the left and right ends. As it flows over the surface of the energy storage battery, it carries away heat, and then through the rectangular heat dissipation window... The air enters the heat dissipation window into the heat dissipation enclosure 12 and is eventually exhausted to the outside of the device by the fan. The equidistant layout of the air intake holes 9 ensures that the cool air enters the enclosure evenly, avoiding local overheating of the energy storage battery due to lack of airflow. The heat dissipation enclosure 12 completely covers the rectangular heat dissipation window, which can prevent external dust and rainwater from entering the energy storage battery box 10 through the window. At the same time, it guides the hot airflow to be discharged in a concentrated manner, improving the heat dissipation efficiency. When the energy storage battery generates heat during charging or discharging, the heat dissipation system can control the temperature inside the box within a safe range, avoiding the risk of life decay or thermal runaway of the energy storage battery due to high temperature.

[0029] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the active emergency fire suppression device 6 is installed at the top of the inverter control top box 5. It ensures the safety of the equipment in case of fire by combining active triggering with efficient fire suppression. The hollow storage box 19 of the active emergency fire suppression device 6 has U-shaped fixing brackets 13 welded to the bottom of both the front and rear ends. The bottom of the U-shaped fixing brackets 13 is fixed to the top outer wall of the front and rear ends of the inverter control top box 5 by welding. The U-shaped structure of the U-shaped fixing brackets 13 can distribute the weight of the hollow storage box 19, avoiding the weld joint from falling off due to single-point force. At the same time, it ensures that the hollow storage box 19 fits tightly with the top of the inverter control top box 5 without shaking. The horizontal length and vertical width of the hollow storage box 19 are exactly the same as those of the inverter control top box 5. This equal-size design allows the fire extinguishing dry powder inside the box to be evenly distributed. The hollow storage box 19 has a recessed rectangular inner groove 15 near the front end, which contains a high-pressure gas cylinder 16. A solenoid valve A17 is fixed at the center of the left inner wall of the rectangular inner groove 15. The outlet of the solenoid valve A17 is connected to the inside of the hollow storage box 19, and the inlet is sealed to the high-pressure gas cylinder 16. The rectangular inner groove 15 can isolate the high-pressure gas cylinder 16 from the fire extinguishing dry powder, so as to avoid damage to the gas cylinder due to pressure collision. The solenoid valve A17 is used as a control switch for high-pressure gas. It is normally closed. When fire extinguishing is required, the solenoid valve A17 is opened, and the high-pressure gas (nitrogen) in the high-pressure gas cylinder 16 rushes into the hollow storage box 19 to provide spray power for the fire extinguishing dry powder.

[0030] like Figure 1 , Figure 4 , Figure 5and Figure 6 As shown, a solenoid valve B22 is sealed and fixed at the center of the bottom of the hollow storage box 19. The bottom outlet of the solenoid valve B22 is connected to the delivery pipe 21. The bottom of the delivery pipe 21 is sealed and connected to the rectangular hollow air distribution plate 14. Multiple spray nozzles 20 are equidistantly arranged at the bottom of the rectangular hollow air distribution plate 14, and the bottom of the spray nozzles 20 penetrates the outer wall of the top of the inverter control top box 5 and communicates with the interior. When the solenoid valve B22 is opened, the fire extinguishing dry powder driven by high-pressure gas enters the rectangular hollow air distribution plate 14 through the delivery pipe 21. The air distribution plate can evenly distribute the dry powder to each spray nozzle 20 (to avoid excessive or insufficient powder in some areas), and then spray it into the interior of the inverter control top box 5 from the spray nozzles 20, covering the inverter and wiring terminals. Key components such as the inverter control top box 5 and the energy storage battery box 10 are installed. At the same time, some dry powder is allowed to seep downward through the connection between the inverter control top box 5 and the energy storage battery box 10 to suppress possible fires in the energy storage battery. A feeding port is provided on the upper side of the center of the rear end of the hollow storage box 19. The feeding port is connected to the inside of the hollow storage box 19. The rear opening is externally sealed with a sealing end cap. The sealing end cap is sealed by threads to ensure that the fire extinguishing dry powder does not get damp or clump during storage (dry powder will lose its fire extinguishing effect if it gets damp). It also prevents high-pressure gas leakage. When the fire extinguishing dry powder is used up or when the stock is low during regular checks, the sealing end cap can be unscrewed to replenish the dry powder through the feeding port. The operation is convenient and does not require disassembly of the device, ensuring that the equipment has a long-term fire extinguishing capability.

[0031] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, a recessed battery compartment is provided at the center of the rear end of the hollow storage box 19, and a self-contained battery box 18 is fixed inside. The self-contained battery box 18 is electrically connected to the inverter control top box 5, solenoid valve A17 and solenoid valve B22 via wires. The self-contained battery box 18 is powered by an independent lithium battery and is completely separated from the main circuit of the equipment (energy storage battery box 10 and inverter control top box 5). When the main circuit is short-circuited or loses power due to fire, the self-contained battery box 18 can still provide power to solenoid valve A17 and solenoid valve B22 to ensure that the fire extinguishing function is triggered normally. At the same time, the power status of the self-contained battery box 18 can be displayed on the touch screen 4 of the inverter control top box 5, which is convenient for users to check regularly and avoid device failure due to battery depletion.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
