Description

Technical Field

[0001] This utility model relates to a high-voltage control box for energy storage devices, and more particularly to a high-voltage energy storage box with a fire protection system. Background Technology

[0002] The high-voltage box of the battery module is responsible for connecting the energy storage battery pack to the external power system, thereby realizing the input and output of electrical energy. The box generally contains circuit breakers, relays, fuses, shunts, battery cluster management unit (BCMU), and switching power supplies. In practical applications, the high-voltage box consists of a low-voltage control circuit and a high-voltage power circuit. It is usually arranged in a confined space with the battery pack. Affected by unstable power factors, once a fire occurs in the high-voltage box, it cannot be extinguished in time and may spread to the battery pack or other energy storage facilities, which can easily lead to a larger-scale fire and explosion accident, causing incalculable losses and consequences. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an energy storage high-pressure box that can spray fire extinguishing medium into the high-pressure box in a timely manner and has high fire extinguishing efficiency, in order to address the shortcomings of the existing technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] A high-pressure energy storage box with a fire-fighting system includes a box body and a fire-extinguishing nozzle. The box body is equipped with a high-pressure control unit. The fire-extinguishing nozzle includes a nozzle body with two selector ends and a spray end. The two selector ends are respectively connected to a preset fire-extinguishing medium delivery device. The spray end passes through the side wall of the box body and the two are fixedly connected. The spray end includes a hemispherical end with multiple spray holes facing different directions. The spray holes are connected to the selector ends.

[0006] Preferably, the spray end includes a threaded portion, and a stepped portion is formed at one end of the threaded portion near the nozzle body. A fastening nut is screwed onto the threaded portion, and the side wall of the housing is sandwiched between the fastening nut and the stepped portion.

[0007] Preferably, the spray end and the two gate ends are distributed in a "T" shape on the nozzle body.

[0008] Preferably, the housing is equipped with a sensor for detecting smoke and / or flame, and the sensor is electrically connected to the control host of the fire extinguishing medium delivery device.

[0009] Preferably, the front side of the housing is provided with a panel, and the panel is provided with a control switch and an electrical connection terminal.

[0010] Preferably, the fire extinguishing nozzle is located on the panel.

[0011] The energy storage high-voltage box with a fire-fighting system disclosed in this utility model has a rectangular box body. Inside, a high-voltage control unit is installed for input / output control of the battery module. A fire-extinguishing nozzle is installed on the front side of the box body. The fire-extinguishing nozzle includes a nozzle body, two selection ends, and a spray end. The two selection ends are respectively used to connect to two fire-extinguishing media provided by a preset fire-extinguishing medium delivery device, such as aerosol fire extinguishing agent and foam fire extinguishing agent.

The housing 1 is equipped with a high-pressure control unit 2. The fire extinguishing nozzle 3 includes a nozzle body 30. The nozzle body 30 is provided with two selection ends 31 and a spray end 32. The two selection ends 31 are respectively connected to a preset fire extinguishing medium delivery device. The spray end 32 passes through the side wall of the housing 1 and the two are fixedly connected. The spray end 32 includes a hemispherical end 33. The hemispherical end 33 is provided with multiple spray holes 34 facing different directions. The spray holes 34 are connected to the selection ends 31.

[0018] In the above structure, the housing 1 is rectangular in shape, and a high-voltage control unit 2 is installed inside for input and output control of the battery module. A fire extinguishing nozzle 3 is installed on the front side of the housing 1. The fire extinguishing nozzle 3 includes a nozzle body 30, two selection ends 31, and a spray end 32. The two selection ends 31 are respectively used to connect to two fire extinguishing media provided by a preset fire extinguishing medium delivery device, such as aerosol fire extinguishing agent and foam fire extinguishing agent. The spray end 32 extends into the housing 1. When fire occurs inside the housing 1... In the event of a fire, a preset fire extinguishing medium delivery device can be controlled to deliver the fire extinguishing agent to the corresponding selection end 31, and then spray it into the housing 1 through the nozzle body 30 and the spray end 32, thereby achieving the function of timely fire extinguishing. At the same time, the end of the spray end 32 has a hemispherical end 33, and the hemispherical end 33 has multiple spray holes 34 facing different directions. By using multiple spray holes 34, the fire extinguishing agent can be sprayed into multiple directions in the housing 1, which not only prevents the occurrence of fire extinguishing dead zones, but also improves the fire extinguishing efficiency.

[0019] To reliably secure the fire extinguishing nozzle 3, in this embodiment, please refer to... Figure 3 and Figure 4 The spray end 32 includes a threaded portion 35, and a stepped portion 36 is formed at one end of the threaded portion 35 near the nozzle body 30. A fastening nut 37 is screwed onto the threaded portion 35, and the side wall of the housing 1 is sandwiched between the fastening nut 37 and the stepped portion 36.

[0020] During assembly, the above structure is first passed through the hole 5 on the side wall of the housing 1 from the outside to the inside. Then, the fastening nut 37 is screwed onto the threaded part 35 on the inside of the housing 1. Based on the clamping fit between the fastening nut 37 and the stepped part 36, the fire extinguishing nozzle 3 is fixed to the side wall of the housing 1.

[0021] To facilitate connection to fire-fighting pipelines, in this embodiment, the spray end 32 and the two selector ends 31 are distributed in a "T" shape on the nozzle body 30.

[0022] As a preferred embodiment, the housing 1 is equipped with a sensor for detecting smoke and / or flames, and the sensor is electrically connected to the control unit of the fire extinguishing medium delivery device. The sensor, control unit, and fire extinguishing medium delivery device form a control loop, which enables automatic detection of the fire situation within the housing 1.

[0024] The energy storage high-pressure box with a fire-fighting system disclosed in this utility model can be equipped with a suction sensor to achieve real-time monitoring of its internal environment. This sensor can accurately detect key parameters such as gas concentration and temperature inside the box. Once an abnormality is detected and it is determined that fire-fighting measures need to be initiated based on a preset severity level, the system will automatically control the opening of the water or gas valve to spray fire-fighting medium into the high-pressure box. At the same time, it will send the current smoke, flame, temperature and other status information to the control host. The control host will then perform linkage control based on the received signals, such as activating alarms and recording events.

[0025] Furthermore, once the fire sprinkler action is triggered, the fire protection system will immediately execute fire extinguishing operations and send a sprinkler dry contact signal to the BMS (Building Management System) host. Upon receiving this signal, the BMS host will quickly identify that it is an emergency command issued by the fire protection system. In order to protect other equipment and systems in the building from the impact of the fire, the BMS will immediately execute preset self-protection actions, such as pressing down to disconnect the battery circuit. This action can ensure that in the event of a fire, critical equipment such as batteries will not cause secondary disasters due to short circuits or overheating, thereby ensuring the fire safety of the overall facility.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
