Description

Technical Field

[0001] The utility model belongs to the technical field of energy storage safety, and in particular relates to a multifunctional interface for energy storage equipment and an energy storage fire protection system. Background Art

[0002] Currently, the safety protection of energy storage equipment in the market primarily relies on independent combustible gas detection equipment and fire suppression nozzles. Combustible gas detection equipment, installed near the equipment, monitors the combustible gas concentration in the air in real time and immediately issues an alarm if it detects an excess. Fire suppression nozzles, on the other hand, typically spray fire suppression agents.

[0003] Existing technologies typically require separate installation and wiring of combustible gas detection equipment and fire suppression systems, resulting in a complex system structure and high installation and maintenance costs. Response speed is also slow: Because combustible gas detection and fire suppression functions are implemented separately, there is a time lag between detection and response, making it impossible to effectively contain a fire in the shortest possible time. Furthermore, multiple independent devices occupy a large amount of space, hindering the compact design of energy storage equipment and increasing its size and weight. Utility Model Content

[0004] The purpose of the present utility model is to provide a multifunctional interface for energy storage equipment and an energy storage fire protection system to solve the problems raised by the background technology.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] In a first aspect, the present invention provides a multifunctional interface for an energy storage device, which is applied to an energy storage device having a combustible gas detection inlet and a fire suppression nozzle. The multifunctional interface includes an interface valve body fixedly mounted on the outer shell of the energy storage device, a quick connector provided at the lower end of the interface valve body and communicating with an internal channel thereof, a channel outlet provided at the upper end of the interface valve body and communicating with the internal channel, and a solenoid valve for controlling the on / off of the internal channel.

[0007] One end of the quick connector opposite to the internal passage is in communication with the combustible gas detection inlet and the fire suppression nozzle;

[0008] The channel outlet is used to collect combustible gas from the energy storage device and to spray fire suppression agents.

[0009] Furthermore, the interface valve body is connected to the external shell of the energy storage device by means of threads, and a mounting baffle and a sealing gasket are provided between the two.

[0010] Furthermore, the internal channel of the interface valve body matches the size of the solenoid valve channel.

[0011] Furthermore, the solenoid valve and the interface valve body are fixed by threaded connection.

[0012] Furthermore, a protective cover is provided on the end surface of the interface valve body away from the external shell of the energy storage device.

[0013] Furthermore, the quick connector is connected to the side of the interface valve body by means of threads, and the quick connector is a gas-liquid common quick connector.

[0014] In the second aspect, the utility model proposes an energy storage fire fighting system, including the above-mentioned multifunctional interface, and also including a protective device with combustible gas detection function and fire suppression function. The protective device is connected to the multifunctional interface through a pipeline and is used for combustible gas inhalation or fire suppression agent spraying.

[0015] The beneficial effects of the present invention are:

[0016] 1. The multifunctional interface in this application is designed to be flexible, supporting both targeted detection and fire suppression of a single battery pack and sequential detection and suppression of multiple battery packs, meeting the needs of different application scenarios. Furthermore, the channel outlet on the interface valve body is designed to be angled upward, ensuring that the agent can fully cover the top of the battery module, improving the fire extinguishing effect.

[0017] 2. This application integrates combustible gas detection and fire suppression functions into a single interface, reducing the number of devices and pipeline connections, thereby reducing the overall cost of the system. At the same time, it optimizes the agent injection path, improves agent utilization, and further reduces usage costs.

[0018] 3. The energy storage fire protection system in this application integrates combustible gas detection and fire suppression functions, enabling efficient and timely monitoring and protection of energy storage equipment (such as battery packs). Once excessive combustible gas concentrations are detected, the fire suppression mechanism is immediately activated, effectively preventing fire accidents. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Example 1

[0026] like Figure 1-2 As shown, this embodiment proposes a multifunctional interface for energy storage equipment, which is applied to energy storage equipment with a combustible gas detection inlet and a fire suppression nozzle. The multifunctional interface includes an interface valve body 5 fixedly installed on the external shell of the energy storage equipment (such as a battery pack), a quick connector 8 provided at the lower end of the interface valve body 5 and connected to its internal channel, a channel outlet 9 provided at the upper end of the interface valve body 5 and connected to the internal channel, and a solenoid valve 6 for controlling the on-off of the internal channel; one end of the quick connector 8 opposite to the internal channel is connected to the combustible gas detection inlet and the fire suppression nozzle; the channel outlet 9 is used to collect combustible gas from the energy storage equipment and to spray fire suppression agent.

[0027] For example, when it is used specifically, the multifunctional interface is installed on the side wall of the battery pack through screws 2 and threaded holes on the interface valve body 5, and a mounting baffle 3 and a sealing gasket 4 are provided between the interface valve body 5 and the outer shell of the battery pack to ensure sealing and increase the installation strength. When performing combustible gas detection, the multifunctional interface is opened. At this time, it is in the air intake state and gas collection can be performed. When the collected gas concentration is too high and an alarm is sounded, fire agent is sprayed. At this time, the multifunctional interface acts as an agent nozzle to spray the agent to the battery pack for fire extinguishing. The channel outlet 9 of the multifunctional interface is designed with an upward angle to ensure that the spray range is not limited by the battery module. This multifunctional interface can perform targeted detection and fire suppression on a single battery pack, or it can perform gas collection and detection on multiple battery packs in sequence, and then spray the agent in a targeted manner to complete the fire suppression.

[0028] Furthermore, the internal passageway of the interface valve body 5 is preferably sized to match the passageway of the solenoid valve 6, and the solenoid valve 6 and interface valve body 5 are secured via a threaded connection. A protective cover 7 is provided on the end face of the interface valve body 5 facing away from the outer casing of the energy storage device to protect the interface valve body and solenoid valve. A quick connector 8 is threadedly connected to the side of the interface valve body 5 and is a gas-liquid compatible quick connector.

[0029] Example 2

[0030] like Figure 3 As shown, this embodiment proposes an energy storage fire protection system, including the multi-function interface 10 proposed in the above embodiment, and also includes a protective device 12 with combustible gas detection function and fire suppression function. The protective device 12 is connected to the multi-function interface 10 through a pipeline 13 and is used for combustible gas inhalation or fire suppression agent spraying.

[0031] It should be noted that, in this embodiment, the combustible gas detection inlet of the protective device 12 and the fire suppression agent of the fire suppression function can share the same pipe fitting or use a pipe fitting separately. When sharing the same pipe fitting, the pipe fitting is directly connected to the multi-function interface 10 through the pipeline 13. When using a pipe fitting separately, the two pipe fittings are first connected to the pipeline 13 and then to the multi-function interface 10.

[0032] Combine Figure 4 During specific use, the protective device 12 with combustible gas detection function and fire suppression function must first use the combustible gas detection function to collect the combustible gas from the battery pack from the multi-function interface 10. When the collected gas concentration is too high and an alarm is sounded, the fire agent is sprayed and ejected from the channel outlet 9 of the multi-function interface 10.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
