[0050] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0051] Example 1

[0052] This embodiment relates to an energy storage cabinet, which aims to improve the safety of the energy storage cabinet by optimizing its structure.

[0053] In terms of overall structure, Figures 1 to 3 As shown, the energy storage cabinet in this embodiment includes an energy storage cabinet body 1 , a water tank 2 , a spray unit 3 and a conveying unit 4 .

[0054] Among them, the water tank 2 is detachably assembled on the top of the energy storage cabinet body 1, the spray unit 3 is arranged on the energy storage cabinet body 1 and includes a nozzle 301 for spraying into the inside of the energy storage cabinet, and the delivery unit 4 is openable and closable and connected in series between the water tank 2 and the spray unit 3.

[0055] As configured above, the energy storage cabinet in this embodiment is provided with a water tank 2 on the top of the energy storage cabinet. When a fire occurs in the energy storage cabinet, water can be sprayed into the energy storage cabinet through the sprinkler unit 3 to extinguish the fire, thereby improving the safety of the energy storage cabinet. The water tank 2 is detachably provided on the top of the energy storage cabinet, which saves the space occupied by the water tank 2 in the horizontal direction and improves the space utilization when multiple energy storage cabinets are arranged. The detachable setting facilitates the assembly and transportation of the water tank 2. The water tank 2 can be assembled according to actual needs, which is beneficial to improving the safety and quality of the energy storage cabinet.

[0056] Specifically, in this embodiment, as an exemplary structure, combined with Figure 1 As shown, the energy storage cabinet in this embodiment includes an energy storage cabinet body 1, which has a receiving cavity. A PDU and a battery cluster are arranged in the receiving cavity. This embodiment does not involve improvements to the PDU and battery cluster inside the energy storage cabinet, so the specific arrangement can refer to the arrangement inside the energy storage cabinet in the prior art.

[0057] In order to facilitate the transportation and handling of energy storage cabinets, Figure 1 and Figure 2 As shown, the energy storage cabinet in this embodiment is provided with a forklift hole 101 at the bottom. The provision of the forklift hole 101 facilitates the transportation and handling of the energy storage cabinet and is conducive to design implementation.

[0058] Specifically, the forklift hole 101 is a square hole that passes through the bottom of the energy storage cabinet. When transporting, the energy storage cabinet can be transported by inserting the fork arm of the forklift into the forklift hole 101.

[0059] In order to better assemble the water tank 2 and the energy storage cabinet body 1, Figure 1 As shown, the energy storage cabinet in this embodiment further includes a connecting unit 5 , and the water tank 2 is detachably assembled on the top of the energy storage cabinet body 1 through the connecting unit 5 .

[0060] In this embodiment, the connection unit 5 includes a connector 501 and a connecting ear 502 fixed to the bottom of the water tank 2. The connector 501 passes through the connecting ear 502 and is connected to the energy storage cabinet body 1, thereby constraining the water tank 2 on the energy storage cabinet body 1. The arrangement of the connector 501 and the connecting ear 502 facilitates assembly of the energy storage cabinet. The connector 501 passes through the connecting ear 502 and is connected to the top of the energy storage cabinet body 1, making it easy to operate and having a simple structure that facilitates implementation.

[0061] More specifically, the connector 501 in this embodiment can be, for example, a bolt, which is threaded into a bolt hole on the top of the energy storage cabinet body 1. Using a bolt as the connector 501 facilitates the use of the base adapter on the top of the energy storage cabinet, simplifies the structure, and facilitates design and implementation.

[0062] It should be noted that currently, a hanging bolt 102 is provided on the top of the energy storage cabinet body 1 to facilitate hanging. The installation position of the hanging bolt 102 is the basic adapter portion on the top of the energy storage cabinet body 1. When the water tank 2 is installed, the hanging bolt 102 is removed. The setting position of the connecting ear 502 corresponds to the installation position of the hanging bolt 102. The connecting piece 501 is passed through the connecting ear 502 and connected to the top of the energy storage cabinet body 1 to complete the assembly of the water tank 2.

[0063] Combine Figure 1 and Figure 3 As shown, the water tank 2 in this embodiment includes a water filling port 201 provided at the top of the water tank 2. The water tank 2 is sealed, and water is filled into the water tank 2 through the water filling port 201 when water needs to be filled. A breathing valve is provided on the top of the water tank 2 to better balance the pressure inside the water tank 2 under different environmental conditions.

[0064] To further increase the water storage capacity of the water tank 2, the connection unit 5 in this embodiment further includes a connection groove 503 disposed at the bottom of the water tank 2, with a connection ear 502 formed at the bottom of the connection groove 503. When the water tank 2 is assembled on top of the energy storage cabinet body 1, the connector 501 is received within the connection groove 503. By providing the connection groove 503 and forming the connection ear 502 at the bottom of the connection groove 503, the space required for connecting the connection ear 502 to the top of the energy storage cabinet body 1 is reduced, resulting in a simple structure and convenient design and implementation.

[0065] Specifically, in this embodiment, when the connecting member 501 is a bolt, it needs to be screwed to be threadedly connected to the top of the energy storage cabinet body 1. In conjunction with this, the width of the connecting groove 503 in this embodiment is sufficient for the tool to screw the bolt, and the height of the connecting groove 503 is sufficient for the bolt to be inserted.

[0066] In order to better observe the liquid level of the water tank 2, the water tank 2 in this embodiment is provided with a liquid level indicator unit 6 to display the liquid level in the water tank 2. The provision of the liquid level indicator unit 6 facilitates observation of the liquid level in the water tank 2, helps to detect abnormalities in the water tank 2, and thus ensures the water level in the water tank 2. The preferred liquid level indicator unit 6 is a liquid level gauge, which makes the water level display more intuitive and easier to observe.

[0067] In order to better improve the spraying effect of the spray unit 3, the spray unit 3 in this embodiment includes multiple nozzles 301 fixedly installed in the energy storage cabinet body 1, and connecting pipes connected to the nozzles 301. The ends of the connecting pipes extend from the interior of the energy storage cabinet body 1 to the top of the energy storage cabinet body 1. The multiple nozzles 301 are beneficial to increasing the spraying area of the spray unit 3 in the energy storage cabinet, thereby improving the spraying effect of the spray unit 3, thereby better extinguishing fires.

[0068] Specifically, a quick connector 302 is provided on the end of the connecting pipe of the spray unit 3 extending from the top of the energy storage cabinet body 1. In order to save the vertical space occupied between the energy storage cabinet and the water tank 2, the quick connector 302 can be assembled on the top of the energy storage cabinet body 1 and only needs to be connected to the delivery unit 4 through the connecting pipe.

[0069] To facilitate assembly, the spray unit 3 can be pre-installed inside the energy storage cabinet body 1. A baffle that can cover the quick connector 302 is provided on the top of the energy storage cabinet body 1 to prevent debris and dust from entering the quick connector 302 before the water tank 2 is assembled.

[0070] To better control the delivery unit 4, in this embodiment, the delivery unit 4 is a water pump. The water pump is electrically connected to the energy storage cabinet's PDU and is configured to be turned on and off by the PDU. The use of a water pump increases the water pressure output by the delivery unit 4. Furthermore, the electrical connection between the water pump and the energy storage cabinet's PDU allows the PDU to control the water pump's on and off, facilitating operation.

[0071] Specifically, the water pump's liquid inlet is connected to the water tank 2 via a pipeline. To ensure normal operation of the water pump when activated, the water pump is powered by an additional power supply to prevent the pump from being unable to activate due to a power outage in the energy storage cabinet. Of course, the delivery unit 4 can also be an electrically controlled valve connected in series between the water tank 2 and the spray unit 3. However, an electrically controlled valve can only open and close, and cannot achieve a pressurization effect. Therefore, this design is not adopted in this embodiment.

[0072] In more detail, in order to facilitate the installation of the water pump, a receiving groove is provided at the bottom of the water tank 2 in this embodiment. The water pump is accommodated in the receiving groove and is connected to the water tank 2 through a pipeline.

[0073] It should be noted that the water tank 2 is provided as part of the water fire protection of the energy storage cabinet. When it is activated, it is a measure that is activated only when the fire protection system of the energy storage cabinet is activated and the fire cannot be controlled to avoid causing greater losses.

[0074] To better control the on / off of the water pump, in this embodiment, a control button 7 is electrically connected to the water pump. To prevent misoperation, the control button 7 is configured to stop the water pump only when the PDU starts it. Normally, the control button 7 cannot directly start the water pump. The configuration of the control button 7 allows for manual intervention to stop the spray unit 3 from spraying into the energy storage cabinet body 1 after the water pump is started.

[0075] The water tank 2 of the energy storage cabinet of this embodiment is detachable, allowing it to be used as an optional accessory and installed on the top of the energy storage cabinet body 1 as needed. When the water tank 2 is installed on the top of the energy storage cabinet body 1, the delivery unit 4 is controlled by the PDU. When the fire protection system of the energy storage cabinet is activated, a signal is sent to the PDU, which controls the water pump to start, thereby pressurizing the water in the water tank 2 and delivering it to the sprinkler unit 3. The sprinkler unit 3 then sprays the water into the energy storage cabinet to control the fire.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
