Description

Technical Field

[0001] This invention relates to the field of photovoltaic building technology, and more specifically to a photovoltaic energy storage building integrated structure. Background Technology

[0002] Building-integrated photovoltaics (BIPV) is a technology that integrates solar power generation devices into buildings, typically by integrating photovoltaic panels into building curtain walls or floors to convert sunlight into electricity. Chinese patent CN 219794293 U discloses a building-integrated photovoltaic panel, comprising a U-shaped wall panel unit. One end of the U-shaped wall panel unit has a central partition fixed inside, and hollow frames are installed at both the top and bottom of the central partition. The cross structure formed by the central partition and the two sets of hollow frames divides the U-shaped wall panel unit into four equal rectangular areas. Solar photovoltaic panels are installed in these rectangular areas. An anti-detachment structure is provided on the inner wall of the U-shaped wall panel unit. A transmission box is fixed to one side of the hollow frame surface. When one set of solar photovoltaic panels malfunctions, a worm gear locking structure releases the locking state of the bidirectional expansion structure for maintenance.

[0003] However, in existing building-integrated photovoltaic (BIPV) structures, separate energy storage facilities are usually configured to store the electricity generated by the photovoltaic panels. This separates the photovoltaic power generation and energy storage devices from the building itself, resulting in additional building space occupation, low energy utilization and management efficiency, and difficulty in inspection and maintenance.

[0004] Therefore, how to effectively improve the space utilization and energy management efficiency of building-integrated photovoltaic (BIPV) structures, and facilitate inspection and maintenance, has become an urgent problem to be solved in this field. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a photovoltaic energy storage building-integrated structure and maintenance method that features high space utilization, stability, reliability, and ease of maintenance.

[0006] To achieve the above objectives, the present invention provides a building-integrated photovoltaic (BIPV) energy storage structure, comprising a photovoltaic panel and a floor slab. The photovoltaic panel is disposed on the top surface of the floor slab, and the floor slab contains several cavities, each with a floor slab base plate at its bottom. The structure also includes an energy storage battery, a maintenance lifting device, and a control system.

[0007] The cavity includes a battery mounting cavity and a battery control cavity. A maintenance base plate is provided at the bottom of the battery mounting cavity. A docking locking assembly is provided on both the inner wall of the battery mounting cavity and the maintenance base plate. The docking locking assembly is configured to lock and unlock the connection between the battery mounting cavity and the maintenance base plate. The energy storage battery is mounted on the maintenance base plate and connected to the photovoltaic panel.

[0008] The maintenance lifting device is disposed in the battery control cavity and connected to the maintenance base plate. The maintenance lifting device is configured to control the lifting and lowering of the maintenance base plate when the docking locking assembly is unlocked.

[0009] The control system is configured to control the operating status of the docking locking assembly and the maintenance lifting device.

[0010] Furthermore, the cavity also includes a cable connection cavity, which is distributed around the battery mounting cavity. A cable is threaded through the cable connection cavity, with one end of the cable connected to the photovoltaic panel and the other end connected to the energy storage battery via a quick-connect connector.

[0011] Furthermore, the bottom of the cable connection cavity adjacent to the battery mounting cavity is provided with a detachable cable base plate.

[0012] Furthermore, the docking locking assembly includes snap-fit ​​baffles respectively disposed on the inner wall of the battery mounting cavity and the maintenance base plate, and mutually adapted to each other, wherein the snap-fit ​​baffles are respectively provided with a permanent magnet and an electromagnet.

[0013] Furthermore, the battery control cavity is distributed on both sides of the battery mounting cavity, and the maintenance lifting device includes a lifting device, a cable and a fixed pulley. The fixed pulley is installed in the battery mounting cavity, one end of the cable is connected to the maintenance base plate, and the other end passes around the fixed pulley and through the battery mounting cavity to connect to the lifting device.

[0014] Furthermore, the maintenance lifting device is equipped with a pressure detection device, which is configured to detect the force value of the lifting device in real time.

[0015] Furthermore, it also includes an alarm device that can determine the force value of the lifting equipment to generate an alarm signal.

[0016] To achieve the above objectives, the present invention provides a method for maintenance of a photovoltaic energy storage building-integrated structure, based on the aforementioned photovoltaic energy storage building-integrated structure, the method comprising:

[0017] Disconnect the energy storage battery from the photovoltaic panel, unlock the battery mounting cavity from the maintenance base plate by locking the docking module, and control the maintenance lifting device to lower the maintenance base plate from the battery mounting cavity, simultaneously lowering the energy storage battery for maintenance.

[0018] After maintenance is completed, the maintenance lifting device raises the maintenance base plate and connects it with the battery housing cavity. The connection locking component locks the connection status between the battery housing cavity and the maintenance base plate, and then connects the energy storage battery and the photovoltaic panel.

[0019] Furthermore, the maintenance method also includes:

[0020] The pressure detection device monitors the stress value of the maintenance lifting device in real time and transmits it to the control system, so that the control system can coordinate the operation of the docking locking component and the maintenance lifting device to ensure the stable placement and lowering of the energy storage battery.

[0021] The photovoltaic energy storage building integrated structure and maintenance method provided by this invention place the energy storage battery in the cavity formed by the floor itself and connect it directly to the photovoltaic panel. This can effectively improve space utilization and ensure energy management and transmission efficiency. At the same time, the maintenance lifting device and docking locking component can achieve stable placement of the energy storage battery and facilitate the lowering of the energy storage battery for maintenance, thereby improving maintenance efficiency and ensuring the stability and reliability of this photovoltaic energy storage building integrated structure.

[0038] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0039] See Figures 1 to 8 The image shows an example of a building-integrated photovoltaic energy storage structure provided by the present invention.

[0040] As shown in the figure, the photovoltaic energy storage building integrated structure in this example mainly includes photovoltaic panels 1, floor slab 2, energy storage battery 3, maintenance lifting device 4, and control system 5.

[0041] A photovoltaic panel 1 is installed on the top surface of a floor slab 2. The floor slab 2 has several cavities inside, and each cavity has a floor slab base plate at its bottom. The cavities include a battery mounting cavity 21 and a battery control cavity 22. A maintenance base plate 23 is provided at the bottom of the battery mounting cavity 21. A docking locking component 24 is provided on the inner wall of the battery mounting cavity 21 and the maintenance base plate 23, respectively. The docking locking component 24 is configured to lock and unlock the connection between the battery mounting cavity 21 and the maintenance base plate 23. The energy storage battery 3 is installed on the maintenance base plate 23 and connected to the photovoltaic panel 1, which can effectively improve the space utilization rate and ensure the energy management and transmission efficiency.

[0042] Furthermore, the maintenance lifting device 4 is installed in the battery control cavity 22 and connected to the maintenance base plate 23. The maintenance lifting device 4 is configured to control the lifting of the maintenance base plate 23 when the docking locking component 24 is unlocked. The control system 5 is configured to control the working status of the docking locking component 24 and the maintenance lifting device 4, so as to achieve stable placement of the energy storage battery 3 and facilitate the lowering of the energy storage battery 3 for maintenance, thereby improving maintenance efficiency and ensuring the stability and reliability of this photovoltaic energy storage building integrated structure.

[0043] Combination Figure 2 and Figure 3 The floor slab 2 is composed of a hollow floor slab or a ribbed floor slab, forming several arrayed cavities based on the structure of the floor slab 2 itself, and includes at least one battery placement cavity 21 for placing the energy storage battery 3, so that the energy storage battery 3 can be placed in the battery placement cavity 21 and directly connected to the photovoltaic panel 1, thereby reducing the building space occupied by the separate deployment of the energy storage system, improving the space utilization rate, and improving the energy transmission efficiency between the photovoltaic panel 1 and the energy storage battery 3, so as to realize the integration of photovoltaic-building structure-energy storage.

[0044] Combination Figure 1 Furthermore, several photovoltaic panels 1 are installed on the top surface of the floor slab 2, and the photovoltaic panels 1 are connected in series to facilitate connection with the energy storage battery 3 via cables 11.

[0045] Combination Figure 3 In conjunction with this, the cavity inside the floor slab 2 also includes several cable connection cavities 25. The cable connection cavities 25 are distributed around the battery mounting cavity 21. Preferably, the several cable connection cavities 25 are arranged side by side on one side of the battery mounting cavity 21, and each cable connection cavity 25 has a cable opening 251 on its inner wall so that one end of the cable 11 is connected to the photovoltaic panel 1, and the other end passes through the cable opening 251 of each cable connection cavity 25 and connects to the energy storage battery 3 installed in the battery mounting cavity 21.

[0046] Furthermore, the cable 11 is connected to the energy storage battery 3 through the quick-connect connector 12, so that the photovoltaic panel 1 and the energy storage battery 3 can be quickly connected and disconnected through the quick-connect connector 12. Before lowering the energy storage battery 3 for maintenance, the connection between the photovoltaic panel 1 and the energy storage battery 3 can be quickly disconnected, ensuring maintenance efficiency and safety, and ensuring the installation stability of the photovoltaic panel 1 and the cable 11.

[0047] Combination Figures 2 to 4 Preferably, the bottom of the cable connection cavity 25 adjacent to the battery mounting cavity 21 is provided with a detachable cable base plate 252, and the quick-connect connector 12 is distributed in the adjacent cable connection cavity 25. In this way, after removing the cable base plate 252, the adjacent cable connection cavity 25 forms an adjacent maintenance port 26. The quick-connect connector 12 can be quickly pulled out through the adjacent maintenance port 26 to disconnect the photovoltaic panel 1 from the energy storage battery 3, which facilitates the subsequent removal and maintenance of the energy storage battery 3.

[0048] Combination Figure 5 and Figure 6In order to achieve stable placement and lowering of the energy storage battery 3, docking locking components 24 are respectively provided on the inner wall of the battery placement cavity 21 and the maintenance base plate 23. The docking locking components 24 are configured to lock and unlock the connection between the battery placement cavity 21 and the maintenance base plate 23, so that when the docking locking components 24 are locked, the energy storage battery 3 can be stably placed in the maintenance base plate 23, and when the docking locking components 24 are unlocked, the maintenance base plate 23 can be removed from the battery placement cavity 21 and lowered, thereby simultaneously lowering the energy storage battery 3 for maintenance.

[0049] Specifically, the docking locking assembly 24 includes snap-on baffles respectively disposed on the inner wall of the battery mounting cavity 21 and the maintenance base plate 23. The second snap-on baffle 242 is distributed along the periphery of the maintenance base plate 23 and cooperates with the maintenance base plate 23 to form a stepped structure. The first snap-on baffle 241 is recessed on the inner wall of the port where the battery mounting cavity 21 and the maintenance base plate 23 cooperate, and is adapted to the second snap-on baffle 242.

[0050] In this way, when the battery mounting cavity 21 is connected to the maintenance base plate 23, the first latching baffle 241 and the second latching baffle 242 can abut against each other and cooperate to accommodate the energy storage battery 3 on the maintenance base plate 23 in the battery mounting cavity 21.

[0051] Combination Figure 5 and Figure 6 Furthermore, the docking locking assembly 24 also includes a magnet assembly. The first latching baffle 241 is provided with a permanent magnet 243, and the second latching baffle 242 is provided with an electromagnet 244. The electromagnet 244 is configured to generate a magnetic force that attracts the permanent magnet 243 when energized, so that the electromagnet 244 and the permanent magnet 243 can approach each other to generate a magnetic attraction.

[0052] Combination Figure 7 Specifically, the electromagnet 244 is connected to the energy storage battery 3 through an electrical circuit 245 embedded inside the maintenance base plate 23, so that the energy storage battery 3 can supply power to the electromagnet 244 through the electrical circuit 245. The electrical circuit 245 is also connected to the control system 5, so that the control system 5 can control the on / off state of the electrical circuit 245, thereby controlling the magnetic state of the electromagnet 244.

[0053] In this example, permanent magnet 243 and electromagnet 244 are respectively located at the four corners of the first latching baffle 241 and the second latching baffle 242, and correspond to each other. The control system 5 is embedded in the maintenance base plate 23 and connected to the power line 245.

[0054] Preferably, the permanent magnet 243 and the electromagnet 244 cover the first latching baffle 241 and the second latching baffle 242 respectively, so as to increase the magnetic attraction force generated by the permanent magnet 243 and the electromagnet 244.

[0055] Here, the permanent magnet 243 and the electromagnet 244 are conventional technical means in this field, and will not be described in detail here. As an example, the permanent magnet 243 can be made of a metal plate with high magnetic permeability (such as low carbon steel), and the electromagnet 244 can be made of an iron core wound with a copper coil.

[0056] Therefore, the control system 5 controls the energizing circuit 245 to close, and the energy storage battery 3 supplies power to the electromagnet 244 through the energizing circuit 245, so that the electromagnet 244 generates magnetic force after being energized. When the battery mounting cavity 21 is connected to the maintenance base plate 23, the magnetic attraction force generated by the permanent magnet 243 and the electromagnet 244 drives the first latching baffle 241 and the second latching baffle 242 to move towards each other and fit tightly, thereby synchronously driving the battery mounting cavity 21 to stably connect with the maintenance base plate 23, and ensuring the connection stability of the battery mounting cavity 21 and the maintenance base plate 23 under the action of magnetic attraction, thereby locking the connection state of the battery mounting cavity 21 and the maintenance base plate 23.

[0057] Correspondingly, the control system 5 shuts off the power supply line 245, and after the electromagnet 244 is de-energized, the electromagnet 244 no longer generates magnetic force, and the magnetic attraction between the permanent magnet 243 and the electromagnet 244 disappears, so that the first latching baffle 241 and the second latching baffle 242 can move away from each other, thereby unlocking the connection between the battery mounting cavity 21 and the maintenance base plate 23, so that the maintenance base plate 23 can be removed from the battery mounting cavity 21 and lowered to place the energy storage battery 3 for maintenance.

[0058] Combination Figure 8 In order to ensure that the maintenance base plate 23 can be stably lowered from the battery mounting cavity 21 and improve the stability of the energy storage battery 3, the cavity inside the floor slab 2 also includes a battery control cavity 22, and a maintenance lifting device 4 is provided in the battery mounting cavity 21 so that the maintenance lifting device 4 can be connected to the maintenance base plate 23 and control the lifting of the maintenance base plate 23.

[0059] Preferably, the battery control cavities 22 are distributed on both sides of the battery placement cavity 21. Each battery control cavity 22 is provided with two sets of maintenance lifting devices 4, which are connected to the control system 5 respectively. This allows the four sets of maintenance lifting devices 4 to cooperate with the four corners of the maintenance base plate 23. The control system 5 can control the four sets of maintenance lifting devices 4 to work synchronously, so as to drive the four corners of the maintenance base plate 23 to lift synchronously, ensuring the lifting stability of the maintenance base plate 23.

[0060] Combination Figure 6 , Figure 8 and Figure 9Specifically, the maintenance lifting device 4 includes a lifting device 41, a cable 42, and a fixed pulley 43. The lifting device 41 is preferably composed of a winch mechanism. The fixed pulley 43 is installed in the battery housing cavity 21 through a fixed pulley rod 44. The inner wall of the battery control cavity 22 is provided with a cable hole 221, so that one end of the cable 42 is connected to the maintenance base plate 23 through a lifting ring 45, and the other end passes around the fixed pulley 43 and through the cable hole 221 to connect to the lifting device 41, so that the lifting device 41 can drive the maintenance base plate 23 to rise and fall synchronously when it raises and lowers the cable 42.

[0061] As an example, after the permanent magnet 243 and electromagnet 244 are de-energized, the docking locking assembly 24 is in the unlocked state, the maintenance base plate 23 can be removed from the battery mounting cavity 21, and the lifting device 41 extends the cable 42, which can drive the maintenance base plate 23 to descend synchronously along the height direction, thereby driving the energy storage battery 3 to be lowered synchronously, facilitating the maintenance of the energy storage battery 3. Figure 4 As shown.

[0062] Correspondingly, the lifting device 41 retracts the cable 42, which can drive the maintenance base plate 23 to rise synchronously along the height direction, thereby driving the energy storage battery 3 to rise synchronously, so that the maintenance base plate 23 and the battery mounting cavity 21 approach and dock with each other. When the maintenance base plate 23 reaches the port of the battery mounting cavity 21, power is supplied to the electromagnet 244. The magnetic attraction force generated by the permanent magnet 243 and the electromagnet 244 will drive the first latching baffle 241 and the second latching baffle 242 to move towards each other and fit tightly, thereby synchronously driving the battery mounting cavity 21 and the maintenance base plate 23 to dock stably and lock the connection state of the battery mounting cavity 21 and the maintenance base plate 23, so as to realize the automatic and rapid docking of the battery mounting cavity 21 and the maintenance base plate 23 and maintain the connection stability. Figure 2 As shown.

[0063] Combination Figure 6 In order to ensure that the control system 5 can supply power to the electromagnet 244 in a timely manner, so that the battery housing 21 can quickly and stably connect with the maintenance base plate 23, a proximity switch 231 is provided on the maintenance base plate 23, so that the proximity switch 231 can detect the distance between the maintenance base plate 23 and the battery housing 21 in real time and transmit it to the control system 5.

[0064] Furthermore, the control system 5 has a preset distance threshold. When the distance between the maintenance base plate 23 and the battery mounting cavity 21 reaches the distance threshold, the control system 5 determines that the maintenance base plate 23 has reached the port of the battery mounting cavity 21, closes the power line 245, and supplies power to the electromagnet 244, thereby ensuring that the permanent magnet 243 and the electromagnet 244 can generate magnetic attraction force in time to drive the battery mounting cavity 21 to quickly dock with the maintenance base plate 23 and lock the connection state.

[0065] Here, the distance threshold can be adaptively adjusted according to the specific application to ensure that when the distance between the maintenance base plate 23 and the battery mounting cavity 21 reaches the distance threshold, the magnetic attraction force generated by the permanent magnet 243 and the electromagnet 244 is sufficient to drive the battery mounting cavity 21 to quickly dock with the maintenance base plate 23.

[0066] In some embodiments, the first latching baffle 241 is also provided with a reed switch at the position corresponding to the permanent magnet 243. The reed switch is connected to the control system 5 and cooperates with the electromagnet 244 and the control system 5 to ensure the reliability of the docking between the maintenance base plate 23 and the battery mounting cavity 21.

[0067] As an example, when the control system 5 closes the power circuit 245, the electromagnet 244 is energized and generates magnetic force. The first latching baffle 241 and the second latching baffle 242 approach and fit together, and drive the electromagnet 244 to approach the reed switch synchronously. The ferromagnetic reed inside the reed switch will be magnetized by the magnetic force of the electromagnet 244, so that the internal contacts of the reed switch close and output a low resistance path (e.g., less than 1Ω), so that the control system 5 determines that the maintenance base plate 23 has been connected to the battery mounting cavity 21 and closes the battery mounting cavity 21.

[0068] Correspondingly, if the first latching baffle 241 and the second latching baffle 242 are not close to each other, the distance between the electromagnet 244 and the reed switch is large, and the ferromagnetic reed inside the reed switch is separated, causing the internal contacts of the reed switch to disconnect the output high resistance path (e.g., greater than 100Ω), so that the control system 5 judges that the maintenance base plate 23 is not reliably connected to the battery mounting cavity 21, thereby judging the connection status of the maintenance base plate 23 and the battery mounting cavity 21.

[0069] Here, the use of reed switches is a conventional technique in this field and will not be elaborated upon further.

[0070] Combination Figure 9 Furthermore, the maintenance lifting device 4 also includes a pressure detection device 46. Preferably, the pressure detection device 46 is composed of a pressure sensor and is built into the lifting device 41 so that the pressure detection device 46 can detect the force value of the lifting device 41 in real time, that is, the tension value generated by the cable 42 on the lifting device 41. The pressure detection device 46 transmits the force value of the lifting device 41 to the control system 5 in real time so that the control system 5 can determine the connection status between the battery mounting cavity 21 and the maintenance base plate 23 based on the force value of the lifting device 41.

[0071] As an example, after the maintenance base plate 23 is removed from the battery mounting cavity 21 and lowered, the weight of the maintenance base plate 23 is entirely borne by the cable 42, so that the cable 42 generates tension on the lifting equipment 41. The pressure detection device 46 detects that the force value of the lifting equipment 41 has increased and is in a fully loaded state. At this time, the control system 5 can determine that the docking locking component 24 is in the unlocked state and can control the lifting equipment 41 to extend the cable 42 to carry out the lowering and maintenance of the energy storage battery 3.

[0072] Correspondingly, the control system 5 controls the lifting device 41 to shorten the cable 42 and supplies power to the permanent magnet 243 and the electromagnet 244, so that when the battery mounting cavity 21 is docked with the maintenance base plate 23, the weight of the maintenance base plate 23 is borne by the magnetic attraction of the permanent magnet 243 and the electromagnet 244. The pressure detection device 46 detects that the force value of the lifting device 41 decreases and gradually approaches zero. At this time, the control system 5 can determine that the docking locking component 24 is in the locked state, and the battery mounting cavity 21 and the maintenance base plate 23 are stably connected, and the photovoltaic panel 1 and the energy storage battery 3 can be connected.

[0073] Here, the control system 5 is a conventional technical means in this field. As an example, the control system 5 can be constructed from an existing PLC.

[0074] Furthermore, this photovoltaic energy storage building integrated structure also includes an alarm device, which can receive the force value of the lifting equipment 41 detected by the pressure detection device 46, and make a judgment based on the force value to generate an alarm signal.

[0075] As an example, when the alarm device determines that the force value of the lifting device 41 changes abruptly, it indicates that the magnetic attraction of the permanent magnet 243 and the electromagnet 244 is insufficient to maintain the locking state of the docking locking component 24, and there is a risk of failure in the connection between the battery housing cavity 21 and the maintenance base plate 23. At this time, the alarm device immediately generates an alarm signal.

[0076] Here, the alarm device can be configured as an audible and visual alarm or connected to the building management system. After receiving the alarm signal, it will trigger an on-site audible and visual alarm or send an alarm to the building management system so that maintenance personnel can respond in a timely manner and carry out maintenance on the docking locking component 24 to prevent the energy storage battery 3 from falling due to connection failure.

[0077] This constitutes the photovoltaic energy storage building integrated structure provided by the present invention. The energy storage battery 3 is placed in the cavity formed by the floor slab 2 itself and is directly connected to the photovoltaic panel 1, which can effectively improve the space utilization rate and ensure the energy management and transmission efficiency.

[0078] Meanwhile, this photovoltaic energy storage building integrated structure can form a dual safety mechanism to ensure the safe placement of the energy storage battery 3. Among them, the docking and locking component 24 forms the first line of defense for the energy storage battery 3 through the cooperation of permanent magnet 243 and electromagnet 244. The magnetic attraction drives the buckle baffle to fit tightly, actively locking the connection state between the battery placement cavity 21 and the maintenance base plate 23, providing a solid foundation for the energy storage battery 3 and ensuring its stable placement.

[0079] Furthermore, the lifting device 41, pressure detection device 46, and alarm device work together to form the second line of defense for the energy storage battery 3, monitoring and analyzing the locking status of the first line of defense in real time (the change in force on the lifting device 41 reflects whether the load has been successfully transferred to the docking locking component 24). Once an abnormal change in force is detected (indicating insufficient magnetic attraction or connection failure risk of the docking locking component 24), the alarm device immediately triggers an audible and visual alarm or reports to the building management system, providing a failure warning so that timely intervention and maintenance can be carried out, effectively preventing the energy storage battery 3 from falling due to connection failure.

[0080] Furthermore, the cooperation of these two lines of defense enables the stable deployment and maintenance of energy storage batteries, thereby improving maintenance efficiency and ensuring the stability and reliability of this photovoltaic energy storage building-integrated structure.

[0081] This invention also provides a method for the maintenance of a photovoltaic energy storage building-integrated structure, based on the photovoltaic energy storage building-integrated structure constructed with the above-mentioned scheme, combined with... Figure 10 This maintenance method includes:

[0082] During maintenance, disconnect the energy storage battery 3 from the photovoltaic panel 1, unlock the connection between the battery mounting cavity 21 and the maintenance base plate 23 using the docking locking component 24, and control the maintenance lifting device 4 to lower the maintenance base plate 23 from the battery mounting cavity 21, simultaneously lowering the energy storage battery 3 for maintenance.

[0083] Specifically, first remove the cable base plate 252 at the bottom of the adjacent maintenance port 26, open the adjacent maintenance port 26, and quickly unplug the quick-connect connector 12 through the adjacent maintenance port 26 to disconnect the photovoltaic panel 1 from the energy storage battery 3, so as to facilitate the subsequent lowering and maintenance of the energy storage battery 3.

[0084] Next, the control system 5 disconnects the power line 245, de-energizes the electromagnet 244, and the magnetic attraction between the permanent magnet 243 and the electromagnet 244 disappears, thereby unlocking the connection between the battery housing cavity 21 and the maintenance base plate 23.

[0085] At the same time, the weight of the maintenance base plate 23 is entirely borne by the cable 42. The pressure detection device 46 detects that the force on the lifting equipment 41 has increased and it is in a fully loaded state. At this time, the control system 5 determines that the docking locking component 24 is in the unlocked state.

[0086] Furthermore, the control system 5 drives the lifting device 41 to extend the cable 42, which in turn drives the maintenance base plate 23 to descend from the battery mounting cavity 21 along the height direction, and simultaneously lowers the energy storage battery 3.

[0087] This allows for the inspection and maintenance of energy storage battery 3.

[0088] After the maintenance is completed, the maintenance lifting device 4 raises the maintenance base plate, connects the maintenance base plate 23 with the battery mounting cavity 21, and the docking locking component 24 locks the connection state between the battery mounting cavity 21 and the maintenance base plate 23, connecting the energy storage battery 3 and the photovoltaic panel 1.

[0089] Specifically, the control system 5 controls the lifting device 41 to shorten the cable 42, thereby lifting the maintenance base plate 23 along the height direction to connect with the battery mounting cavity 21, and simultaneously lifting the energy storage battery 3.

[0090] Meanwhile, the proximity switch 231 detects the distance between the maintenance base plate 23 and the battery mounting cavity 21 in real time and transmits it to the control system 5. When the distance between the maintenance base plate 23 and the battery mounting cavity 21 reaches the distance threshold, the control system 5 determines that the maintenance base plate 23 has reached the port of the battery mounting cavity 21, closes the power line 245, and supplies power to the electromagnet 244.

[0091] When the electromagnet 244 is energized, it generates magnetic force, which in turn generates magnetic attraction between the electromagnet 243 and the permanent magnet 243. This drives the first latching baffle 241 and the second latching baffle 242 to move toward each other and fit tightly together. This synchronously drives the battery mounting cavity 21 to stably connect with the maintenance base plate 23, and locks the connection between the battery mounting cavity 21 and the maintenance base plate 23 under the action of magnetic attraction.

[0092] At the same time, the pressure detection device 46 detects that the force value of the lifting device 41 decreases and gradually approaches zero. At this time, the control system 5 determines that the docking locking component 24 is in a locked state, and the battery placement cavity 21 and the maintenance base plate 23 are stably connected, so that the photovoltaic panel 1 and the energy storage battery 3 can be connected.

[0093] Next, the quick-connect connector 12 is quickly connected through the adjacent access port 26 to connect the photovoltaic panel 1 and the energy storage battery 3, and then the cable base plate 252 at the bottom of the adjacent access port 26 is installed.

[0094] Complete the overhaul of energy storage battery 3.

[0095] Furthermore, the pressure detection device 46 continuously monitors the force value of the lifting device 41 in real time and transmits it to the control system 5 and the alarm device. When the alarm device determines that the force value of the lifting device 41 changes abruptly, it indicates that the magnetic attraction force of the permanent magnet 243 and the electromagnet 244 is insufficient to maintain the locking state of the docking locking component 24, and there is a risk of failure in the connection between the battery mounting cavity 21 and the maintenance base plate 23. At this time, the alarm device immediately generates an alarm signal so that the maintenance personnel can respond in time and carry out maintenance on the docking locking component 24 to prevent the energy storage battery 3 from falling due to connection failure.
