Technical Field

[0001] This invention relates to the field of energy storage equipment technology, and in particular to an integrated photovoltaic and energy storage cabinet. Background Technology

[0002] Photovoltaic-storage integrated cabinets generate a large amount of heat during battery charging and discharging. In traditional photovoltaic-storage integrated cabinets, the heat generated by the transformer components during operation and the heat generated by the battery operation are superimposed, affecting heat dissipation efficiency; the cooling components blow directly onto the battery pack, causing the cold air to only flow past the near end of the battery pack and then return directly to the return air vent, resulting in excessively high temperatures at the far end of the battery pack, creating a temperature difference and shortening the battery cycle life; traditional equipment has a delayed response to the smoke signals in the early stages of battery thermal runaway, resulting in untimely handling of thermal runaway accidents, which can easily lead to the spread of fire or gas leaks. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to solve at least one of the technical problems mentioned above.

[0004] The solution to the technical problem of this invention is: an integrated photovoltaic and energy storage cabinet, comprising a cabinet body, a cabinet door, a battery assembly, a transformer assembly, a fire protection assembly, and a temperature control assembly; the cabinet body has an installation space, and the cabinet door is hinged to the cabinet body to open or close the installation space; the installation space is divided from top to bottom into a battery compartment, an air duct compartment, and a transformer compartment; the battery assembly is disposed in the battery compartment; the transformer assembly is disposed in the transformer compartment, and the battery assembly and the transformer assembly are connected by wires; the temperature control assembly includes an air conditioner and an air duct, the air conditioner is fixedly installed on the cabinet door, and the air outlet of the air conditioner faces the door. The air duct compartment has its return air vent facing the battery compartment. A duct connects the battery compartment and the air duct compartment. One end of the duct extends to the far end of the battery assembly away from the air conditioner, forming an opening towards the battery assembly. This opening guides the cold air blown from the air conditioner's outlet into the air duct compartment, flows through the duct, passes through the battery assembly, and returns to the air conditioner's return air vent, forming a circulating air-cooling path. The fire-fighting component includes a smoke and temperature sensor and a fire extinguishing device installed within the battery compartment. The smoke and temperature sensor provides an activation signal to activate the fire extinguishing device when smoke or abnormal temperature is detected.

[0005] As a further improvement to the above technical solution, a pressure regulating component is also included. The pressure regulating component includes a pressure sensor installed inside the battery compartment and an exhaust pressure relief valve installed on the cabinet door and connected to the battery compartment. The pressure sensor is used to provide a start signal to activate the exhaust pressure relief valve to release pressure when it detects that the air pressure inside the battery compartment exceeds a preset safety value.

[0006] As a further improvement to the above technical solution, the pressure regulating component also includes a pressure relief component, which includes a pressure relief plate and an explosion-proof connection structure. The cabinet door is provided with a pressure relief port communicating with the battery compartment. One end of the pressure relief plate is hinged to the cabinet door to open or close the pressure relief port. The explosion-proof connection structure is disposed between the end of the pressure relief plate away from the hinge axis and the cabinet door. The explosion-proof connection structure is used to provide a pre-tightening force to the pressure relief plate to keep it in a closed state. When a momentary high pressure is generated in the battery compartment due to thermal runaway or other reasons, and the pressure difference between the inside and outside of the pressure relief plate exceeds the set value corresponding to the pre-tightening force, the explosion-proof connection structure fails, and the pressure relief plate rotates around its hinge end to open, so as to quickly release the internal pressure.

[0007] As a further improvement to the above technical solution, the explosion venting connection structure includes an explosion venting bolt fixed to the end of the pressure relief plate away from the hinge axis and an explosion venting release plate sleeved on the explosion venting bolt; the cabinet door is provided with a limiting hole that mates with the explosion venting bolt; the diameter of the explosion venting release plate is larger than the diameter of the limiting hole, and it abuts against the side of the cabinet door near the battery compartment to apply a preload to the pressure relief plate; the explosion venting release plate is designed to fail by undergoing plastic deformation or fracture when subjected to tensile force exceeding a set threshold.

[0008] As a further improvement to the above technical solution, the fire protection component also includes a hazardous gas sensor installed in the battery compartment and an audible and visual alarm installed on the outside of the cabinet. The hazardous gas sensor is used to detect the concentration of hazardous gases in the battery compartment and provides a signal to activate the audible and visual alarm when a preset threshold is reached.

[0009] As a further improvement to the above technical solution, a lifting ring is also included, which is fixed to the top of the cabinet.

[0019] The integrated photovoltaic and energy storage cabinet generates a large amount of heat during battery charging and discharging. In traditional integrated photovoltaic and energy storage cabinets, the heat generated by the transformer component 300 during operation is superimposed on the heat generated by the battery operation, affecting the heat dissipation efficiency; the cooling component blows directly onto the battery module 200, causing the cold air to only flow past the near end of the battery module 200 and then directly return to the return air vent, resulting in excessively high temperatures at the far end of the battery pack, creating a temperature difference and shortening the battery cycle life; traditional equipment has a delayed response to the smoke signal in the early stage of battery thermal runaway, resulting in untimely handling of thermal runaway accidents, which can easily lead to the spread of fire or gas leakage.

[0020] Therefore, this invention proposes an integrated optical storage cabinet, referring to... Figures 1-3It includes a cabinet 100, a cabinet door 110, a battery assembly 200, a transformer assembly 300, a fire protection assembly 400, and a temperature control assembly 500. The cabinet 100 has an installation space, and the cabinet door 110 is hinged to the cabinet 100 to open or close the installation space. The installation space is divided from top to bottom into a battery compartment, an air duct compartment, and a transformer compartment. The battery assembly 200 is located in the battery compartment. The transformer assembly 300 is located in the transformer compartment, and the battery assembly 200 is connected to the transformer assembly 300 via electrical wires. The temperature control assembly 500 includes an air conditioner 510 and an air duct 520. The air conditioner 510 is fixedly installed on the cabinet door 110, and the air outlet of the air conditioner 510 faces the air duct compartment. The return air vent of the air conditioner 510 faces the battery compartment. The air duct 520 connects the battery compartment and the air duct chamber. One end of the air duct 520 extends to the far end of the battery assembly 200 away from the air conditioner 510 and forms an opening facing the battery assembly 200. This opening guides the cold air blown out of the air outlet of the air conditioner 510 into the air duct chamber, flows through the air duct 520, passes through the battery assembly 200, and returns to the return air vent of the air conditioner 510, forming a circulating air-cooled path. The fire-fighting component 400 includes a smoke and temperature sensor 410 and a fire extinguishing device 420 installed in the battery compartment. The smoke and temperature sensor 410 provides an activation signal to activate the fire extinguishing device 420 when smoke or abnormal temperature is detected.

[0021] Cabinet 100 and cabinet door 110 provide physical support and protection; battery module 200 stores DC power generated by photovoltaic power generation and outputs DC power when the load needs power or the grid is shaving peak power; transformer module 300 converts the DC power output by battery module 200 into AC power that meets the load requirements or grid connection standards; air conditioner 510 is fixed on cabinet door 110, does not occupy the space inside the compartment, and provides stable cold air; air duct 520 connects the battery compartment and the air duct compartment, guiding the cold air to flow directionally to the far end of battery module 200 to ensure coverage; smoke and temperature sensor 410 monitors the smoke and temperature inside the battery compartment in real time, and provides a signal to activate fire extinguishing device 420 when abnormalities occur; after receiving the sensor signal, fire extinguishing device 420 sprays fire extinguishing medium into the battery compartment to suppress the fire and cool it down. The battery and transformer assembly 300 are physically isolated to prevent the mutual influence of electric arc and high temperature; the smoke and temperature sensor 410 detects signs of thermal runaway in advance, and together with the directional fire extinguishing device 420, shortens the time for handling safety accidents and reduces the risk of fire spread and gas leakage; the closed-loop air-cooling circulation and directional air duct 520 ensure the stable temperature of the battery compartment and prevent the battery from experiencing capacity decay due to high temperature.

[0022] The direct current (DC) generated by the photovoltaic power generation system is stored in the battery module 200 inside the battery compartment via cables. When power is needed, the battery module 200 outputs DC power, which is transmitted to the transformer module 300 in the transformer compartment via wires, and converted into AC power to supply the load or connect to the grid. When the temperature of the battery compartment is too high, the air conditioner 510 at the cabinet door 110 is activated, and the air outlet blows cold air into the air duct compartment. After the cold air gathers in the air duct compartment, it enters the air duct 520, flows to the far end of the battery module 200, and blows towards the battery through the opening of the air duct 520. The cold air absorbs heat to form a hot airflow, which naturally flows to the return air vent of the air conditioner 510, is drawn into the air conditioner 510 for cooling, and then circulates again, forming a closed-loop air-cooling path. In the early stage of thermal runaway of the battery module 200, if the diaphragm is damaged and smoke is generated, the smoke and temperature sensor 410 detects the abnormal signal, immediately sends an early warning to the controller, and triggers the fire extinguishing device 420. The fire extinguishing device 420 quickly sprays the medium to cover the entire area of ​​the battery compartment and prevents the accident from spreading.

[0023] If overpressured gas cannot be released from the battery compartment in time, the pressure increase may exceed the bearing capacity of the steel plate of the cabinet 100, causing the cabinet 100 to bulge and deform, welds to crack, or even the cabinet door 110 to burst open due to the sudden increase in pressure, resulting in structural damage to the equipment. Therefore, in one embodiment, a pressure regulating component 600 is also included. The pressure regulating component 600 includes a pressure sensor 610 disposed in the battery compartment and an exhaust pressure relief valve 620 disposed on the cabinet door 110 and communicating with the battery compartment. The pressure sensor 610 is used to provide a start signal to activate the exhaust pressure relief valve 620 to release pressure when it detects that the gas pressure in the battery compartment exceeds a preset safety value. The pressure sensor 610 and the exhaust pressure relief valve 620 form an active overpressure protection circuit, which strictly controls the air pressure in the battery compartment within a safe threshold, preventing the cabinet 100 and cabinet door 110 from being subjected to overload pressure, reducing the risk of structural damage to the equipment, and extending the service life of the cabinet 100. The directional pressure relief channel allows overpressured gas to be discharged along a preset path, preventing the disorderly diffusion of harmful gases, protecting the safety of surrounding personnel and environmental stability, and reducing losses caused by accidents. Together with the smoke and temperature sensing fire protection system and the directional temperature control system, it forms a triple monitoring system of temperature, smoke, and air pressure, covering the entire process of battery thermal runaway from early warning to later handling.

[0024] Instantaneous high pressure may exceed the response capability of the active valve. The pressure may exceed the pressure resistance limit of the cabinet 100 before the valve is opened, causing the cabinet 100 to deform as a whole, the weld to tear, or even the cabinet 100 to explode. Therefore, in one embodiment, the pressure regulating assembly 600 further includes a pressure relief assembly, which includes a pressure relief plate 630 and an explosion relief connection structure 640. The cabinet door 110 is provided with a pressure relief port communicating with the battery compartment. One end of the pressure relief plate 630 is hinged to the cabinet door 110 to open or close the pressure relief port. The explosion relief connection structure 640 is disposed between the end of the pressure relief plate 630 away from the hinge axis and the cabinet door 110. The explosion relief connection structure 640 is used to provide a pre-tightening force to the pressure relief plate 630 to keep it in a closed state. When a momentary high pressure is generated in the battery compartment due to thermal runaway or other reasons, and the pressure difference between the inside and outside of the pressure relief plate 630 exceeds the set value corresponding to the pre-tightening force, the explosion relief connection structure 640 fails, and the pressure relief plate 630 rotates around its hinge end to open, so as to quickly release the internal pressure. The addition of the pressure relief assembly provides passive pneumatic protection. The pressure relief plate 630 can open rapidly in the instant of generating high pressure, reducing the pressure inside the chamber to a safe range within hundreds of milliseconds, preventing damage to the cabinet 100 structure due to pressure impact, and improving the equipment's survivability in extreme scenarios. It complements the exhaust pressure relief valve 620, ensuring that even if the active valve fails due to power failure or malfunction, the pressure relief plate 630 can still reliably trigger pressure relief, eliminating blind spots in safety protection. The pressure relief plate 630 opens directionally around the hinge end, with a fixed pressure relief path, which can prevent disordered gas jets and debris splashing, reducing secondary hazards to the surrounding environment, personnel, and equipment, and making the impact range of the accident controllable.

[0025] Traditional passive connection structures are inconvenient to assemble and disassemble, and replacement after pressure relief requires complete disassembly, affecting equipment recovery efficiency. Therefore, in one embodiment, the explosion relief connection structure 640 includes an explosion relief bolt 641 fixed to the end of the pressure relief plate 630 away from the hinge axis and an explosion relief release piece 642 sleeved on the explosion relief bolt 641; the cabinet door 110 is provided with a limiting hole that mates with the explosion relief bolt 641; the diameter of the explosion relief release piece 642 is larger than the diameter of the limiting hole, and it abuts against the side of the cabinet door 110 near the battery compartment to apply a preload to the pressure relief plate 630; the explosion relief release piece 642 is designed to fail by undergoing plastic deformation or fracture when subjected to tensile force exceeding a set threshold. The explosion relief plate 642 fails through plastic deformation or fracture at a pre-set weak point, without producing sharp fragments, thus completely avoiding secondary short circuits or personal injury caused by fragments; after depressurization, there is no need to replace the explosion relief bolt 641 or repair the cabinet door 110, shortening the maintenance time of a single component and reducing equipment operation and maintenance costs and downtime losses.

[0026] Traditional equipment lacks intuitive outdoor early warning devices, which can easily lead to delayed emergency response due to information transmission delays, amplifying accident risks. Therefore, in one embodiment, the fire protection component 400 also includes a hazardous gas sensor 430 installed inside the battery compartment and an audible and visual alarm 440 installed on the outside of the cabinet 100. The hazardous gas sensor 430 is used to detect the concentration of hazardous gases inside the battery compartment and provides a signal to activate the audible and visual alarm 440 when it reaches a preset threshold. When the sensor detection value reaches the preset warning threshold, the audible and visual alarm 440 will emit a high-decibel sound and a high-brightness flashing alarm, providing an intuitive alarm prompt to surrounding personnel. By setting up the hazardous gas sensor 430, multi-dimensional and real-time monitoring of the environmental status inside the battery compartment can be achieved, significantly improving the early identification capability of abnormal situations such as thermal runaway, fire, and leakage; the setting of the audible and visual alarm 440 enhances the timeliness and intuitiveness of emergency response, helping operators to take safety measures immediately, and further ensuring the operational safety and maintainability of the photovoltaic-storage integrated cabinet in complex outdoor environments.

[0027] During hoisting, the hoisting force may act on weak points such as the cabinet door 110 and the joints of the compartment, potentially causing deformation of the cabinet door 110, cracking of the compartment welds, or even displacement of the internal battery assembly 200 and transformer assembly 300. Therefore, in one embodiment, lifting rings 700 are also included, which are fixed to the top of the cabinet 100. Four lifting rings 700 are provided, symmetrically fixed at the four corners of the top of the cabinet 100, to ensure balanced force during hoisting; no additional hoisting fixtures need to be made or rented, and it can be directly adapted to general hoisting equipment, saving deployment time per trip; standardized lifting points ensure that the hoisting force acts on the load-bearing structure of the cabinet 100, avoiding damage to weak points, while ensuring the horizontal stability of the cabinet 100 during hoisting, preventing displacement of internal components, and reducing the probability of failure after equipment deployment.

[0028] Since the cabinet 100 is in contact with the ground, it may be corroded by ground water and moisture, leading to rust on the bottom of the cabinet 100. Therefore, in one embodiment, the bottom of the cabinet 100 is provided with a base 710, which is used to raise the height of the cabinet 100 off the ground. The base 710 is provided with a forklift hole 711. The base 710 raises the cabinet 100 to isolate it from ground moisture, reducing the risk of bottom rust and short circuits, and enabling the equipment to adapt to rainy and humid outdoor environments. The forklift hole 711 is compatible with common forklifts, reducing the cost of each loading and unloading operation, facilitating short-distance relocation, and is especially suitable for narrow spaces. During maintenance, the forklift can lift the cabinet 100, providing ample space for bottom inspection and reducing disassembly steps.

[0029] If water accumulation is not detected in time, it can lead to a decrease in electrical insulation performance and cause faults such as short circuits and component corrosion once it comes into contact with the transformer assembly 300 and wire interfaces at the bottom. Therefore, in one embodiment, a water immersion sensor 800 is also included, which is used to detect the water accumulation at the bottom of the cabinet 100. The water immersion sensor 800 monitors the risk of water accumulation in real time, interrupts the accident chain in advance, prevents electrical insulation degradation and corrosion, and improves the overall environmental adaptability of the machine. The water immersion sensor 800 includes two parallel electrode plates. When water submerges the electrode plates, the capacitance value changes, thereby detecting the water immersion.

[0030] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described.
