Description

Technical Field

[0001] This utility model belongs to the field of perovskite photovoltaic power station maintenance technology, and specifically relates to a mobile repair system for perovskite photovoltaic power stations. Background Technology

[0002] The stability of perovskite materials has been a key bottleneck restricting the large-scale commercialization of perovskite photovoltaic modules during long-term outdoor operation. Due to the combined effects of factors such as humidity, temperature, light, bias voltage, and ion migration, perovskite photovoltaic modules are prone to performance degradation and reduced output power.

[0003] Currently, a common performance recovery method in the industry involves applying an external bias voltage or constant current to the repair interface reserved on the back of the perovskite photovoltaic module. Through a reverse electric field or charge redistribution, defects in the perovskite material are repaired, thereby restoring the photoelectric performance of the perovskite photovoltaic module. Existing repair schemes generally employ the fixed installation of a lithium battery or independent power module on the back of each perovskite photovoltaic module, forming a closed-loop repair circuit. While this method enables autonomous repair of individual perovskite photovoltaic modules, it also has significant drawbacks: 1. High cost: Each perovskite photovoltaic module requires lithium batteries, power management circuits, and protection devices, which will significantly increase the system construction and operation and maintenance costs in large-scale power plants.

[0004] 2. Low utilization rate: Perovskite photovoltaic modules do not require repair at all times, and the cells are idle most of the time, resulting in serious waste of resources.

[0005] 3. Safety hazards and reliability issues: The outdoor environment is complex with large temperature and humidity variations. Long-term exposure of a large number of distributed batteries can easily lead to safety problems such as aging, short circuits, swelling, and leakage, while also increasing the difficulty of maintenance.

[0006] 4. Poor scalability: Because the repair power supply is strongly bound to the individual perovskite photovoltaic module, it is difficult to achieve flexible power scheduling, and it is also not conducive to centralized management and remote control. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a mobile repair system for perovskite photovoltaic power plants. It uses a centralized repair power supply to perform targeted bias or constant current repair on multiple perovskite photovoltaic modules, achieving flexible mobility, rapid access and efficient repair. At the same time, it reduces power supply configuration, lowers system costs, thereby reducing the overall operating cost of the power plant and improving the reliability and service life of the modules.

[0008] This invention is implemented as follows: a mobile repair system for a perovskite photovoltaic power station is provided. The perovskite photovoltaic power station includes multiple perovskite photovoltaic module arrays, each array comprising multiple perovskite photovoltaic modules arranged together. The mobile repair system is located at the bottom of each perovskite photovoltaic module array. The mobile repair system includes a control module and a repair component, a horizontal movement component, and a lifting component controlled by the control module. The repair component is mounted on the horizontal movement component, which is mounted on the lifting component. A repair connection port is provided on the repair component, and a module connection port is provided on each perovskite photovoltaic module. The horizontal movement component drives the repair component to move laterally to approach the perovskite photovoltaic module to be repaired. The lifting component drives the horizontal movement component to move the repair component up and down, thereby causing the repair connection port and the module connection port to abut against each other to form a conductive connection, or causing the repair connection port and the module connection port to detach and disconnect the conductive connection. The repair component applies a set bias voltage or constant current to the perovskite photovoltaic module to be repaired through the conductive repair connection port and the module connection port to perform bias repair.

[0009] Furthermore, the lifting assembly includes a support column, a cylinder, and a lifting bracket. The cylinder is mounted on the support column, and the lifting bracket is mounted on top of the cylinder. At least two cylinders simultaneously drive the lifting bracket to move up and down.

[0010] Furthermore, the lateral movement assembly includes a rotating motor, a screw, and a guide rod mounted on the lifting bracket. A screw seat and a guide rod seat are respectively mounted on the repair assembly. The screw seat and guide rod seat are respectively connected to the screw and guide rod, so that the repair assembly is sleeved on the screw and guide rod. The rotating motor drives the screw to rotate, thereby driving the repair assembly to move laterally left and right along the guide rod through the screw seat.

[0011] Furthermore, the mobile repair system also includes a control box, in which a control module is installed. A power module is also installed in the control box, which provides power to the repair component, the traversing component, and the lifting component.

[0012] Furthermore, a cable connects the repair component to the control box, and a cable chain is attached to the cable, which is laid on the lifting bracket.

[0013] Compared with existing technologies, the mobile repair system for perovskite photovoltaic power plants of this invention has the following characteristics: 1. Significantly reduced costs: Instead of configuring an independent repair module for each perovskite photovoltaic module, the repair task of the entire array of perovskite photovoltaic modules can be completed with just one centralized repair module, saving material and maintenance costs.

[0014] 2. High flexibility: The repair component can move freely between arrays of multiple perovskite photovoltaic modules, accurately connecting to the target perovskite photovoltaic module and avoiding resource waste.

[0015] 3. Simple maintenance and high security: The repair system has a simple structure and standardized interfaces, which facilitates on-site operation and maintenance; centralized power supply facilitates unified monitoring and protection, reduces the hidden dangers caused by distributed batteries, and is suitable for large-scale power plant operation scenarios.

[0016] 4. Strong compatibility: The repair system is suitable for various perovskite photovoltaic module types and array layouts, and is also compatible with existing solar power plant infrastructure.

[0017] 5. High repair efficiency: Quick connection between the repair interface and the module interface saves manual operation time; centralized control improves repair accuracy and consistency, and enhances the performance recovery effect of perovskite photovoltaic modules.

Detailed Implementation

[0020] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please refer to the following at the same time Figure 1 as well as Figure 2As shown, a preferred embodiment of the mobile repair system for a perovskite photovoltaic power station is presented. The perovskite photovoltaic power station includes multiple perovskite photovoltaic module arrays A, each array A comprising multiple perovskite photovoltaic modules B arranged together. The mobile repair system is located at the bottom of each perovskite photovoltaic module array A. The mobile repair system includes a control module (not shown) and repair components 1, lateral movement components 2, and lifting components 3 controlled by the control module. The multiple perovskite photovoltaic module arrays A are fixed to the ground by multiple support bases 13.

[0022] The mobile repair system also includes a control box 4, within which a control module is housed. A power module (not shown in the figure) is also installed in the control box 4, providing power to the repair assembly 1, the lateral movement assembly 2, and the lifting assembly 3.

[0023] The repair component 1 is mounted on the horizontal movement component 2, which is mounted on the lifting component 3. A repair connection port (not shown in the figure) is provided on the repair component 1, and a component connection port (not shown in the figure) is provided on each perovskite photovoltaic module B.

[0024] The lateral movement component 2 drives the repair component 1 to move laterally towards the perovskite photovoltaic module B to be repaired. The lifting component 3 drives the lateral movement component 2 to move up and down, thereby causing the repair component 1 to move up and down as well. This allows the repair connection port and the module connection port to abut against each other to form a conductive connection, or to disconnect the conductive connection by separating the repair connection port from the module connection port. The repair component 1 applies a set bias voltage or constant current to the perovskite photovoltaic module B to be repaired through the conductive repair connection port and the module connection port, performing bias voltage repair. The repair connection port and the module connection port are plug-in connectors that can be inserted and removed from each other.

[0025] Specifically, the lifting assembly 3 includes a support column 5, a cylinder 6, and a lifting bracket 7. The cylinder 6 is mounted on the support column 5, and the lifting bracket 7 is mounted on top of the cylinder 6. At least two cylinders 6 simultaneously drive the lifting bracket 7 to move up and down. Figure 2 As shown, a cylinder 6 is installed at each of the left and right ends of the lifting bracket 7.

[0026] Specifically, the lateral movement assembly 2 includes a rotary motor 8, a screw 9, and a guide rod 10 mounted on the lifting bracket 7. A screw seat and a guide rod seat (not shown in the figure) are respectively provided on the repair assembly 1, and the screw seat and guide rod seat are respectively connected to the screw 9 and the guide rod 10, so that the repair assembly 1 is sleeved on the screw 9 and the guide rod 10. The rotary motor 8 drives the screw 9 to rotate through a reducer (not shown in the figure), thereby driving the repair assembly 1 to move laterally along the guide rod 10 via the screw seat. A screw shaft seat 14 is provided on the lifting bracket 7 to support the screw 9.

[0027] Specifically, a cable 11 connects the repair component 1 to the control box 4, and a cable chain 12 is attached to the cable 11. The cable chain 13 is laid on the lifting bracket 7. The cable chain 12 ensures that the wires 11 inside move smoothly during the lateral movement of the repair component 1.

[0028] This utility model also discloses a portable repair method for perovskite photovoltaic power plants. The repair method uses the portable repair system for perovskite photovoltaic power plants described above, and the repair method includes the following steps: Step 1: Based on the location of the perovskite photovoltaic module B to be repaired, the control module controls the horizontal moving component 2 to move the repair component 1 from its initial position to that position. Simultaneously, the control module controls the lifting component 3 to move the repair component 1 and the horizontal moving component 2 upwards together. Movement stops after the repair connection port and the module connection port make conductive contact. A limit switch or pressure sensor is used to provide feedback on the signal indicating conductive contact between the repair connection port and the module connection port, and the control module then stops the lifting component 3.

[0029] Step 2: The control module controls repair component 1 to repair the perovskite photovoltaic module B until the repair is complete. During the repair process, repair component 1 monitors the repair current, voltage, and time in real time, and can perform overcurrent, overvoltage, or overtemperature protection according to the set protection thresholds. If any abnormality is detected, the repair output will stop immediately. The repair continues until the preset repair time is reached or the current and voltage are monitored to reach the expected stable state. At this point, repair component 1 stops the bias or constant current output, ending the repair process for the perovskite photovoltaic module B.

[0030] Step 3: The control module controls the lifting component 3 to move the repair component 1 and the horizontal moving component 2 downwards together, so that the repair connection port and the component connection port are disengaged. The control module controls the horizontal moving component 2 to move the repair component 1 back to the initial position, waiting for the next repair cycle.

[0031] If multiple perovskite photovoltaic modules B in the same array need to be repaired, repeat steps one through three above in sequence until all perovskite photovoltaic modules B to be repaired are repaired.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
