[0004] Single DC power supply device: provides stable DC power to meet the needs of devices that require DC power supply. However, DC power supply has problems such as limited power supply range.

[0052] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0053] Embodiment 1:

[0054] The present invention provides an AC / DC power supply device, comprising a cabinet 1, wherein an AC power supply module 100, a DC power supply module 600, a photovoltaic power supply module 200, a switching control module 300, an energy storage module 400, a monitoring module 500 and a battery module 800 are installed inside the cabinet 1, the photovoltaic power supply module 200, the AC power supply module 100, and the DC power supply module 600 are connected via the switching control module 300 and the energy storage module 400, and the AC power supply module 100 is used to connect to an external AC power grid to convert AC power into a voltage and current suitable for use by the device;

[0055] The DC power supply module 600 can provide a stable DC power supply to meet the needs of devices that require DC power supply;

[0056] The photovoltaic power supply module 200 uses solar panels to convert solar energy into electrical energy to provide energy for the device;

[0057] The switching control module 300 automatically switches different power supply modules according to different power supply requirements and actual conditions to ensure the stability and reliability of power supply;

[0058] The energy storage module 400 is used to store excess electrical energy for different types of batteries and release energy when the power supply is insufficient, thus playing a role of buffering and backup;

[0059] The monitoring module 500 is used for wireless communication between the device and the platform, and monitoring the device operation data and real-time parameters;

[0060] The main device 700 is used for AC and DC power supply, and the main device 700 is connected to the photovoltaic power supply module 200, the AC power supply module 100, the DC power supply module 600 and the energy storage module 400;

[0061] The battery module 800 is used to store excess energy for use as backup power, and the battery module 800 is connected to the main device 700 .

[0062] The present invention also provides a power supply method for an AC / DC power supply device, the method comprising the following steps:

[0063] S1. When the external AC power grid is supplying power normally, the AC power supply module 100 is used to supply power to the device first. At the same time, the photovoltaic power supply module 200 converts solar energy into electrical energy, part of which is directly supplied to the device, and the excess electrical energy is stored in the energy storage module 400.

[0064] S2. When the AC power grid fails or the power supply is unstable, the switching control module 300 automatically switches to the DC power supply module 600 or the photovoltaic power supply module 200 to ensure continuous power supply of the equipment; if the power supply capacity of the DC power supply module 600 and the photovoltaic power supply module 200 is insufficient, the energy storage module 400 will release the stored electric energy to provide emergency power supply for the equipment;

[0065] S3. When there is sufficient sunlight, the photovoltaic power supply module 200 can independently power the equipment and store the excess electrical energy in the energy storage module 400; when it is night or when there is insufficient sunlight, the switching control module 300 switches to the AC power supply module 100 or the DC power supply module 600 according to the actual situation.

[0066] Grid status monitoring: The switching control module 300 continuously monitors the voltage, current, frequency and other parameters of the external AC grid. By comparing with the preset normal range, it can be determined whether the AC grid is supplying power normally. If the grid parameters exceed the normal range, or a power outage or other fault occurs, the switching control module 300 will trigger the switching action.

[0067] Photovoltaic power supply module 200 monitoring, real-time monitoring of the output voltage, current and power of the photovoltaic power supply module 200. This can not only understand the power generation of the photovoltaic panel, but also determine whether it can meet the power supply needs of the equipment. At the same time, monitor environmental factors such as the temperature and light intensity of the photovoltaic panel to better evaluate the reliability of photovoltaic power supply.

[0068] The DC power supply module 600 monitors the output voltage and current of the DC power supply module 600 to ensure its stable output. If the DC power supply module 600 fails or the output is abnormal, the switching control module 300 will take corresponding measures.

[0069] The energy storage module 400 monitors the power status of the energy storage module 400 in real time, including the remaining power, charging status, and discharging status. According to the power status of the energy storage module 400, the switching control module 300 can decide whether to enable the energy storage module 400 to supply power, and when to charge the energy storage module 400.

[0070] Switching decision algorithm: Under normal circumstances, the AC power supply module 100 has the highest priority because the external AC power grid can usually provide a stable and reliable power supply. When the AC power grid is supplying power normally, the switching control module 300 preferentially selects the AC power supply module 100 to supply power to the device.

[0071] The photovoltaic power supply module 200 is second. When the AC power grid fails or the power supply is unstable, the switching control module 300 will evaluate the power generation capacity of the photovoltaic power supply module 200. If the photovoltaic power supply can meet part or all of the power supply needs of the device, it will switch to the photovoltaic power supply module 200. The DC power supply module 600 is used as a backup power supply method. When both AC and photovoltaic power supply are unavailable, the switching control module 300 will consider using the DC power supply module 600. The energy storage module 400 is used in emergency situations. When other power supply modules cannot meet the power supply needs of the device, the energy storage module 400 will release the stored electric energy to provide emergency power supply for the device.

[0072] The switching control module 300 comprehensively determines whether switching is required based on the various parameters monitored. For example, if the voltage of the AC power grid drops to a certain level and the duration exceeds a preset threshold, the switching control module 300 will determine that the AC power grid has a fault and will start the switching process.

[0073] When the output power of the photovoltaic power supply module 200 is greater than the required power of the device and the power of the energy storage module 400 has not reached saturation, the switching control module 300 can choose to store excess photovoltaic power in the energy storage module 400 while continuing to use the photovoltaic power supply module 200 to power the device.

[0074] If the output of the DC power supply module 600 is stable and can meet the power supply demand of the device, and both AC and photovoltaic power supply are unavailable, the switching control module 300 will switch to the DC power supply module 600.

[0075] In order to avoid affecting the device during the switching process, the switching control module 300 adopts a smooth switching technology. During the switching process, the output power of the current power supply module is gradually reduced, and the output power of the target power supply module is gradually increased, so that the power supply of the device can be smoothly transitioned.

[0076] For example, when switching from AC power supply to photovoltaic power supply, the switching control module 300 first slowly reduces the output of the AC power supply module 100, while gradually increasing the output of the photovoltaic power supply module 200. During the switching process, the power supply voltage and current of the device are always kept stable to avoid voltage fluctuations or current shocks.

[0077] If a fault occurs during the switching process, the switching control module 300 will immediately stop the switching and take corresponding fault handling measures. For example, if a photovoltaic panel is found to be faulty when switching to the photovoltaic power supply module 200, the switching control module 300 will re-evaluate the availability of other power supply modules and try to switch to other reliable power supply modules.

[0078] After switching to the new power supply module, the switching control module 300 continues to monitor the power supply situation. If it is found that the new power supply module cannot meet the power supply demand of the device, or other problems occur, the switching control module 300 will make a switching decision again to ensure continuous and stable power supply of the device.

[0079] For example, if the output power of the photovoltaic power supply module 200 decreases due to insufficient light after a period of time, the switching control module 300 may switch to the AC power supply module 100 or the DC power supply module 600, or enable the energy storage module 400 for power supply according to the actual situation.

[0080] By obtaining detailed information such as the number of battery cells through RS485 and combining it with the adaptive charge and discharge circuit, more accurate management of the battery can be achieved. For example, the remaining capacity of the battery can be accurately calculated based on the number of battery cells, and overcharging and over-discharging can be avoided during the charge and discharge process to extend the battery life. Since it can adapt to 48V and 60V batteries, the device can be compatible with battery systems of different voltages, reducing the dependence on specific voltage batteries and improving the versatility of the device in different application scenarios. RS485 communication supports remote data transmission, which is convenient for users to monitor and maintain the battery system remotely. For example, in the application of energy storage systems, information such as the number of battery cells, charge and discharge status, etc. can be viewed in real time in the central control room, and problems can be discovered and handled in a timely manner.

[0081] By integrating AC, DC and photovoltaic power supply modes, and setting up a switching control module 300 and an energy storage module 400, it is possible to automatically switch under different power supply conditions to ensure continuous and stable power supply to the equipment, and effectively avoid power outages caused by failure of a single power supply mode; it is possible to flexibly select a suitable power supply mode according to different equipment requirements and actual power supply conditions to meet the power supply requirements of various occasions; when the AC power grid is supplying power normally, the excess photovoltaic power is stored in the energy storage module 400 and released for use when needed, thereby improving energy utilization efficiency.

[0093] In this embodiment, the side water bag 14 serves the function of collecting water. At the same time, it can slow down the rate of temperature drop inside the cabinet 1 in weather with a large temperature difference between day and night. The collected water will flow along the top side water bag 14 through the through water pipe 15 to the lowest side water bag 14 for storage. When the water in the side water bag 14 is full, the water in the side water bag 14 at the bottom will enter the top side water bag 14 through the connecting water pipe 16 and flow out through the overflow pipe 17. The water flowing out of the overflow pipe 17 can clean the side wall of the cabinet 1, thereby ensuring that the side wall of the cabinet 1 is in a clean state.

The arc-shaped water collecting trough 11 can store and collect water for a short time. The water enters the leakage pipe 13 through the leakage hole 10 at the bottom of the arc-shaped water collecting trough 11, and enters the top side water bag 14 through the leakage pipe 13 to be collected.

[0101] In this embodiment, the fan blades 41 can be blown by the external wind, and the transmission column 42 is driven to rotate by the fan blades 41. During the rotation, the transmission column 42 synchronously drives the movable inner gear ring 44 to move. During this process, the limit plate 442 and the movable inner gear ring 44 synchronously make regular movements. At this time, the limit column 443 reciprocates along the outer wall of the guide plate 47, which limits the movement trajectory of the movable inner gear ring 44 and ensures the stability of the movable inner gear ring 44 during the movement. During the sliding of the movable inner gear ring 44 along the inner wall of the pushing frame 45, it also pushes the pushing frame 45 to move left and right. During the movement of the pushing frame 45 to the left and right, it can push the cleaning brushes 46 arranged on both sides to move synchronously. During the movement of the cleaning brush 46 to the left and right, the top of the cabinet 1 is cleaned, which can avoid the accumulation of dead branches and leaves on the top of the cabinet 1 and the blockage of the leakage hole 10.

[0102] In one embodiment, the inner wall of the pushing frame 45 is provided with a limiting sliding groove 451 , and sliding blocks are fixedly connected to both sides of the movable inner gear ring 44 , and the sliding blocks are slidably connected in the movable inner gear ring 44 .

[0103] In this embodiment, the limiting slide groove 451 provided on the inner wall of the pushing frame 45 serves to limit the moving inner gear ring 44, and the sliding blocks provided on both sides of the moving inner gear ring 44 can slide along the inner wall of the limiting slide groove 451, thereby increasing the stability of the moving inner gear ring 44 during movement. In the process of the moving inner gear ring 44 sliding along the inner wall of the pushing frame 45, it also pushes the pushing frame 45 to move left and right. In the process of moving left and right, the pushing frame 45 can push the cleaning brushes 46 provided on both sides to move synchronously.

[0104] Working principle: when it is necessary to install the components, the components to be installed inside the cabinet 1 are placed between the two clamps 24. The clamps 24 clamp and fix the components. The side walls of the clamps 24 are wavy, and the wavy side is made of anti-slip material to ensure that the clamped components are more stable. The wires connected on both sides of the components can be placed in the wire groove 26. In the process of placing the wires in the wire groove 26, the wires can slide downward along the inclination angle set on the upper surface of the clamp 28, and at the same time push the clamp 28 to move toward the two inner walls of the wire groove 26. During this process, the return spring 27 is compressed. When the wire slides to the bottom of the wire groove 26, the clamp 28 returns to the initial position under the push of the return spring 27 to block the wire. The clamp 28 can limit the wire, so that the wires on both sides of the component can be placed neatly to avoid the wires being entangled and affecting subsequent inspection and maintenance.

[0105] The mounting plate 21 plays the role of installation and support. The sliding plate 25 is pulled toward the middle of the mounting plate 21 by tightening the spring 23, so that the two clamping plates 24 can move toward the middle of the mounting plate 21 to clamp the components. The two clamping plates 24 can clamp components of different sizes, which increases the applicability of the power supply device. The sliding plate 25 can slide along the inside of the sliding groove 22 to ensure the stability of the sliding plate 25 during the sliding process; multiple mounting plates 21 are connected to the same grounding wire 19, and the grounding wire 19 can conduct electrons to the ground, which has an anti-static effect.

[0106] When encountering windy and rainy weather, rainwater will flow along the top of the cabinet 1 to the arc-shaped water collection tank 11 for collection. The arc-shaped water collection tank 11 can store and collect water for a short time. The water enters the leakage pipe 13 through the leakage hole 10 at the bottom of the arc-shaped water collection tank 11, and enters the uppermost side water bag 14 through the leakage pipe 13 for collection. The collected water will flow along the top side water bag 14 through the through water pipe 15 to the lowermost side water bag 14 for storage. When the side water bag 14 When the water in the cabinet is full, the water in the side water bag 14 at the bottom will enter the uppermost side water bag 14 through the connecting water pipe 16 and flow out through the overflow pipe 17. The water flowing out of the overflow pipe 17 can clean the side wall of the cabinet 1 to ensure that the side wall of the cabinet 1 is in a clean state. The wind can blow the fan blades 41, and the fan blades 41 drive the transmission column 42 to rotate. The transmission column 42 synchronously drives the moving inner gear ring 44 to move during the rotation process. The moving inner gear ring 44 moves The cleaning brushes 46 arranged on both sides can be pushed to move synchronously during the left and right movement. The cleaning brushes 46 can clean the top of the cabinet 1 during the left and right movement, so as to avoid the accumulation of dead branches and leaves on the top of the cabinet 1, and at the same time, avoid the blockage of the water leakage hole 10. During this process, the limit plate 442 and the mobile inner gear ring 44 make regular movements synchronously. At this time, the limit column 443 reciprocates along the outer wall of the guide plate 47, which limits the movement trajectory of the mobile inner gear ring 44 and ensures the stability of the mobile inner gear ring 44 during the movement. The limit slide groove 451 arranged on the inner wall of the pushing frame 45 limits the mobile inner gear ring 44, and the sliders arranged on both sides of the mobile inner gear ring 44 can slide along the inner wall of the limit slide groove 451, further increasing the stability of the mobile inner gear ring 44 during the movement.
