Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power supply equipment technology, and in particular to an energy storage battery protection device. Background Technology

[0002] Against the backdrop of rapid development in renewable energy, photovoltaic (PV) energy storage power supplies have been widely used due to their ability to flexibly store and utilize electrical energy. However, existing protection devices for PV energy storage power supplies still have significant shortcomings in practical applications: First, they have poor scalability. When it is necessary to increase the energy storage capacity, it is difficult to quickly add or remove battery modules through standardized battery compartments. Adding or removing batteries is very inconvenient, and the arrangement of batteries is messy, leading to chaotic wiring and poor space utilization. Second, after expansion, multiple battery modules are piled up together, resulting in poor heat dissipation. Local temperature exceeding the limit can accelerate battery aging and even cause the risk of thermal runaway, seriously restricting the reliability and service life of PV energy storage systems. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, the purpose of this utility model is to provide an energy storage battery protection device with a reasonable spatial distribution of the battery compartment, which facilitates the increase or decrease of the number of batteries and ensures the heat dissipation effect of the batteries.

[0005] To achieve the above objectives, this utility model proposes an energy storage battery protection device, including a battery compartment, a ventilation assembly, and a clamping assembly. The clamping assembly is disposed on the side wall of the battery compartment and includes a connecting plate, grippers, and a tension spring. The grippers are disposed through the side wall of the battery compartment. The connecting plate is disposed between the grippers on the same side of the battery compartment. The tension spring is disposed between the connecting plate and the side wall of the battery compartment. A compartment cover is provided on the top of the battery compartment. The ventilation assembly is disposed on the battery compartment and includes an air inlet and an exhaust pump. The air inlet is located on the top of the battery compartment, and the exhaust pump is located on the bottom of the battery compartment.

[0006] Furthermore, a base is provided at the bottom of the battery compartment, a support spring is provided on the base, and a battery support plate is provided on the top of the support spring.

[0007] Furthermore, the battery tray is provided with a through-hole for ventilation, and the upper surface of the battery tray is also provided with a raised pad.

[0008] Furthermore, the battery compartment has multiple sets of grippers on each side, and each set of grippers is connected to each other by a connecting plate. Adjacent sets of grippers are arranged vertically. The battery compartment is provided with guide grooves, which are slidably adapted to the grippers. Both the upper and lower ends of the grippers are chamfered.

[0009] Furthermore, a buffer pad is provided at the bottom of the compartment cover, and a buckle is provided at the connection between the compartment cover and the battery compartment.

[0010] Furthermore, a protective filter screen is provided on the air intake window, an exhaust hood is provided at the air intake end of the exhaust pump, a filter screen is provided inside the exhaust hood, and an exhaust pipe is provided at the air outlet end of the exhaust pump.

[0011] Beneficial effects: This utility model adds a clamping component and a ventilation component inside the battery compartment. The battery compartment adopts a vertical stacking method, which has a small horizontal footprint and reasonable spatial distribution, making it convenient to increase or decrease the number of batteries. The clamping claws in the clamping component support and clamp the side walls of the vertically distributed batteries in the battery compartment, and there is a gap between the clamping claws and the battery compartment to facilitate the circulation ventilation of the ventilation component. At the same time, air is introduced through the air inlet window at the top of the battery compartment, and the exhaust pump at the bottom removes heat from the battery compartment, ensuring stable heat dissipation inside the battery compartment.

Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] The energy storage battery protection device of this utility model embodiment will now be described with reference to the accompanying drawings.

[0020] like Figures 1-3 As shown, the energy storage battery protection device provided in this embodiment of the present invention includes a battery compartment 1, a ventilation assembly 4, and a clamping assembly 2. The clamping assembly 2 is disposed on the side wall of the battery compartment 1 and includes a connecting plate 21, a gripper 22, and a tension spring 23. The gripper 22 is disposed through the side wall of the battery compartment 1, the connecting plate 21 is disposed between the grippers 22 on the same side of the battery compartment 1, and the tension spring 23 is disposed between the connecting plate 21 and the side wall of the battery compartment 1. A compartment cover 3 is provided on the top of the battery compartment 1.

[0021] The ventilation assembly 4 is installed on the battery compartment 1 and includes an air intake window 41 and an exhaust pump 43. The air intake window 41 is located at the top of the battery compartment 1 and the exhaust pump 43 is located at the bottom of the battery compartment 1.

[0022] Specifically, when using the energy storage battery protection device of this application, the battery compartment 1 is fixed in a designated position. By opening the compartment cover 3 on the top of the battery compartment 1, the batteries are installed one by one into the battery compartment 1 according to the number of batteries used, and then the compartment cover 3 is closed. Since the battery compartment 1 adopts a vertical stacking method for the batteries, the horizontal space is small, the space distribution is reasonable, and it is convenient to increase or decrease the number of batteries.

[0023] In the battery clamping compartment, the gripper 22 is subjected to the squeezing force of the battery sidewall to the connecting plate 21. The connecting plate 21 applies the squeezing force to the tension spring 23, so that the gripper 22 elastically supports and clamps the vertically distributed battery sidewalls in the battery compartment 1. Since there is a gap between the gripper 22 and the battery compartment 1, it is convenient for the ventilation component 4 to circulate and ventilate, so that the heat of the battery sidewall is transferred in time. During the ventilation process in the battery compartment 1, air is introduced through the air inlet 41 at the top of the battery compartment 1, and the exhaust pump 43 at the bottom exhausts the heat in the battery compartment 1, ensuring stable heat dissipation inside the battery compartment 1.

[0024] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a base 5 is provided at the bottom of the battery compartment 1, a support spring 6 is provided on the base 5, and a battery tray 61 is provided on the top of the support spring 6. A vent hole 62 is provided through the battery tray 61, and a raised pad 63 is also provided on the upper surface of the battery tray 61 to create a gap at the bottom of the battery tray 61, which facilitates heat dissipation at the bottom of the battery tray 61.

[0025] Specifically, when the battery is placed in the battery compartment 1, the support spring 6 at the bottom of the battery compartment 1 provides elastic support to the battery tray 61, thereby providing stable support to the bottom of the battery, making the top of the battery in close contact with the compartment cover 3, and the gripper 22 provides elastic support to the side wall of the battery, reducing the amount of battery movement within the battery compartment 1.

[0026] During the ventilation process of the ventilation component 4, the air entering through the air inlet window 41 moves downward along the gap in the inner wall of the battery compartment 1, and some of the air moves downward through the vent 62 at the bottom of the battery tray 61, so as to transfer the heat at the bottom of the battery in time and fully ensure the heat dissipation effect of the battery.

[0027] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the battery compartment 1 has multiple sets of grippers 22 on each side. Each set of grippers 22 is connected to each other by a connecting plate 21. The grippers 22 of adjacent sets are arranged vertically. The battery compartment 1 is provided with a guide groove 24, which slides and adapts to the grippers 22. Both the upper and lower ends of the grippers 22 are chamfered.

[0028] Specifically, the grippers 22 in each group clamp the sidewalls of the batteries in the vertical layer, ensuring that the batteries in each vertical layer are stably supported and protected within the battery compartment 1. The chamfers at the top and bottom of the grippers 22 facilitate the insertion and removal of the batteries.

[0029] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a buffer pad 32 is provided at the bottom of the cover 3 to buffer and protect the battery at the top of the battery compartment 1. A buckle 31 is provided at the connection between the cover 3 and the battery compartment 1 to facilitate a stable connection between the cover 3 and the battery compartment 1.

[0030] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a protective filter screen is provided on the air intake window 41, an exhaust hood 42 is provided at the air intake end of the exhaust pump 43, a filter screen is provided inside the exhaust hood 42, and an exhaust pipe 44 is provided at the air outlet end of the exhaust pump 43 to filter the gas in the battery compartment 1, reduce dust generation, and protect the dust-free environment inside the battery compartment 1.

[0031] To clearly illustrate the above embodiments, refer to Figures 1-3The specific working principle of the energy storage battery protection device of this utility model is as follows: When using the energy storage battery protection device of this application, the battery compartment 1 is fixed in a designated position by the base 5. During the battery installation process, the compartment cover 3 on the top of the battery compartment 1 is opened, and the batteries are installed one by one into the battery compartment 1 according to the number of batteries to be installed, and then the compartment cover 3 is closed. After the battery is placed into the battery compartment 1, the support spring 6 at the bottom of the battery compartment 1 provides elastic support to the battery support plate 61, thereby providing stable support to the bottom of the battery and making the top of the battery in close contact with the compartment cover 3.

[0032] Because the battery compartment 1 uses a vertically stacked battery method, it occupies less horizontal space, has a reasonable spatial distribution, and facilitates the addition or removal of the number of batteries. In the clamping compartment, the grippers 22 move elastically under the pressure of the battery sidewalls, acting on the connecting plate 21. The connecting plate 21 then applies the pressure to the tension spring 23, causing the grippers 22 to elastically support and clamp the vertically distributed batteries in the battery compartment 1, reducing the amount of battery movement within the battery compartment 1.

[0033] Because there is a gap between the gripper 22 and the battery compartment 1, the ventilation component 4 can circulate and ventilate, so that the heat on the side wall of the battery can be transferred in time. During the ventilation process in the battery compartment 1, the air entering through the air inlet 41 moves downward along the gap in the inner side wall of the battery compartment 1, and some of the air moves downward through the vent 62 at the bottom of the battery support plate 61, which fully ensures the heat dissipation effect of the battery. Finally, the hot air in the battery compartment 1 is discharged through the exhaust pump 43, ensuring stable heat dissipation inside the battery compartment 1.

[0034] In summary, the energy storage battery protection device of this utility model adds a clamping component and a ventilation component inside the battery compartment. The battery compartment adopts a vertically stacked battery method, which has a small horizontal footprint and reasonable spatial distribution, making it convenient to increase or decrease the number of batteries. The clamping claws in the clamping component support and clamp the side walls of the vertically distributed batteries in the battery compartment, and there is a gap between the clamping claws and the battery compartment to facilitate the ventilation component for circulating ventilation. At the same time, air is introduced through the air inlet window at the top of the battery compartment, and the exhaust pump at the bottom dissipates the heat in the battery compartment, ensuring stable heat dissipation inside the battery compartment.

[0035] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
