Technical Field

[0001] This utility model belongs to the technical field of photovoltaic energy storage cabinet battery pack installation, specifically relating to a photovoltaic energy storage cabinet battery pack installation bracket. Background Technology

[0002] Photovoltaic energy storage systems play a crucial role in the renewable energy sector. They not only store electricity generated by solar power systems for use at night or during cloudy / rainy weather, but also interact with the power grid to achieve peak shaving and valley filling, improving grid stability and efficiency. However, traditional photovoltaic energy storage systems face numerous challenges in battery installation, connection, maintenance, and thermal management, limiting their performance and economic viability in large-scale applications.

[0003] Traditional photovoltaic energy storage cabinets often require complex tools and manual operation when installing batteries, which is not only time-consuming and labor-intensive, but also prone to damaging the batteries during installation, affecting their lifespan and performance stability. In addition, the connection between the batteries and the energy storage system is usually relatively fixed, making it difficult to adjust or replace batteries once installation is complete. This limits the system's flexibility during operation and the convenience of maintenance.

[0004] In terms of connecting cells to photovoltaic modules, traditional connection methods often rely on rigid connections, such as welding or screw fixing. This not only increases the complexity and time cost of the connection process but also reduces the reliability of the connection, especially its stability under long-term operation and environmental changes. In addition, if a cell in the battery pack fails, the replacement or maintenance process is complicated and often requires downtime, affecting the operating efficiency of the entire system.

[0005] Traditional photovoltaic energy storage systems are often not designed with ease of maintenance in mind. Once the system needs to be upgraded or maintained, it often requires complex operations, and some components may even need to be completely disassembled, which increases maintenance costs.

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.

[0029] This utility model provides, for example Figures 1-5The photovoltaic energy storage cabinet battery pack mounting bracket shown includes a cabinet body 1. A cabinet door 2 is rotatably connected to the front left side of the cabinet body 1 for sealing the interior of the cabinet body 1. A cooling air conditioner 3 is installed inside the upper right side of the cabinet body 1 for cooling the cabinet body 1. A battery insertion plate 4 is installed inside the front of the cabinet body 1. Multiple battery insertion holes 5 extend through the front and rear of the battery insertion plate 4, and each of the multiple battery insertion holes 5 contains an energy storage battery. Multiple partition brackets 6 are fixedly connected to the rear of the battery insertion plate 4. Multiple rollers 7 are rotatably connected between the multiple partition brackets 6, and the multiple rollers 7 are located on the lower rear side of the multiple battery insertion holes 5 and at the lower end of the energy storage batteries.

At the rear, the front ends of two electrode tubes 9 in the same group are connected to the energy storage battery. The energy storage battery is installed inside the energy storage cabinet via a mounting bracket, which consists of a battery insertion plate 4 and multiple partition brackets 6. During the installation of the energy storage battery, the energy storage battery is inserted into the mounting bracket through multiple battery insertion holes 5 that run through the front and rear of the battery insertion plate 4. Multiple rollers 7 on the lower rear side of the battery insertion holes 5 assist in the insertion of the energy storage battery, making it easier to insert the energy storage battery into the mounting bracket. The two electrode tubes 9 directly behind the multiple battery insertion holes 5 are connected to the photovoltaic module, and the two electrode tubes 9 are fixed inside the circuit connection plate 8 set at the rear end between the multiple partition brackets 6. This allows the energy storage battery to be installed, so that multiple energy storage batteries can form an energy storage battery pack for the photovoltaic module. Each energy storage battery can be connected individually, making it easier to maintain and repair the energy storage battery pack.

[0030] Preferably, a wire harness connecting post 10 is fixedly connected to the lower end of the electrode insertion tube 9, and the wire harness connecting post 10 passes through the interior of the lower end of the electrode insertion tube 9. A connector 12 is elastically connected inside the electrode insertion tube 9 via a connecting spring 11, and the connector 12 is slidably connected inside the front end of the electrode insertion tube 9 and located at the front end of the connecting spring 11. A wire harness fixing bolt 13 passes through the rear end of the wire harness connecting post 10, and the wire harness fixing bolt 13 is threaded into the interior of the rear end of the circuit connection board 8. A wire harness is connected inside the lower end of the wire harness connecting post 10 and is connected to the photovoltaic module through the wire harness. This connection is made between the energy storage battery and the photovoltaic module. During the process, since the lower end of the electrode tube 9 is connected to the wire harness connecting column 10, and the lower end of the wire harness connecting column 10 is internally connected to the wire harness connected to the photovoltaic module, and the wire harness is fixed by the wire harness fixing bolt 13, the energy storage battery can be connected to the photovoltaic module through the insertion between the two electrodes at the rear end and the two electrode tubes 9 directly behind the battery socket 5. When the two electrodes at the rear end of the energy storage battery are inserted into the two electrode tubes 9, the electrode tubes 9 can be tightly connected to the two electrodes of the energy storage battery through the connector 12 with the elastic connection at the front end, thereby ensuring the stable connection between the energy storage battery and the photovoltaic module.

[0031] Preferably, an adjustment groove 14 is provided inside the lower front side of the battery socket 5. The inner walls of both ends of the adjustment groove 14 are connected to limit slots 15.

After the energy storage battery is inserted into the battery socket 5, the energy storage battery can be locked and fixed by the locking clip 22 on the lower front side to prevent the energy storage battery from sliding out of the battery socket 5, ensuring a stable connection between the energy storage battery and the two electrode tubes 9. Since the locking clip 22 is elastically connected to the clamping slider 17 set inside the lower front side of the battery socket 5 through the telescopic spring 20 and the connecting slide plate 21, and is connected to the unlocking button 23 through the connecting slide plate 21, the locking clip 22 can be fully retracted into the clamping slider 17 by pressing the unlocking button 23, allowing the energy storage battery to be smoothly pulled out of the battery socket 5, making it easier to maintain and repair the energy storage battery.

[0032] Preferably, limiting slide rods 16 are fixedly connected between the inner walls of the front and rear ends of the two limiting slots 15, and the two limiting slide rods 16 pass through the left and right ends of the clamping slider 17 respectively.

The clamping slider 17 is elastically connected inside the adjusting groove 14 by two clamping springs 18, and the two clamping springs 18 are respectively sleeved on the outside of the two limiting slide rods 16 and located on the left and right sides of the front end of the clamping slider 17, for locking and fixing the energy storage battery. During the process, since the clamping slider 17 is elastically connected to the adjustment groove 14 opened inside the lower front side of the battery socket 5 through the clamping springs 18 on both sides of the front end, the locking head 22 can be slid to the rear end of the energy storage battery by pulling the clamping slider 17 forward, so that the locking head 22 can be smoothly locked onto the rear end of the energy storage battery and lock and fix the energy storage battery. At the same time, the locking head 22 can push the energy storage battery backward under the action of the clamping slider 17 and the two clamping springs 18, so that the energy storage battery can be more tightly connected to the two electrode tubes 9 at the rear end.
