Description

Technical Field

[0001] The utility model belongs to the technical field of power system safety protection, and in particular relates to an emergency power-off control cabinet. Background Art

[0002] With the continuous development of power systems, batteries are increasingly used as emergency power sources in power systems. In key areas such as power systems, data centers, and communication base stations, the safety performance of battery cabinets is crucial to the stable operation of the entire system. However, existing battery cabinets often lack effective automatic fire extinguishing devices when facing emergencies such as a sharp increase in ambient temperature.

[0003] Traditional battery cabinet fire prevention methods mainly rely on external fire protection systems for intervention. These methods have problems such as slow response time and limited fire extinguishing effect. In addition, some small or independently operated power systems may not be equipped with a complete fire protection system, and their safety risks cannot be ignored.

[0004] A technology called "Villa Elevator Control Cabinet with Power Outage Emergency" (publication number: CN220351404U) provides a solution, mainly for the emergency power supply problem of the elevator system in the event of a power outage. The technology is composed of an integrated emergency box, electric cabinet and battery system, as well as a heat sink and air inlet box, etc., to solve the problem of overheating of the power system during an elevator power outage emergency. The solution provides a heat dissipation module to ensure the operating stability of the emergency control cabinet group for elevator power outages, solving the problem of high temperature of the self-provided power emergency module caused by a sudden interruption of the mains supply.

[0005] Although the "Villa Elevator Control Cabinet with Power Outage Emergency" provides an effective solution in the field of elevator power outage emergency, its main focus is on providing emergency power supply and heat dissipation, rather than directly solving the fire hazard that may be caused by the battery cabinet under extreme temperature conditions. In the wider application of power systems, especially considering the rapid increase in ambient temperature that the battery cabinet may encounter, there is still a need for an emergency power outage control cabinet that can automatically start the fire extinguishing procedure to more directly deal with the risk of fire. Utility Model Content

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide an emergency power outage control cabinet, which can automatically start the fire extinguishing program when the ambient temperature rises sharply, quickly and effectively cool the battery or cover it with dry powder, thereby preventing or slowing down the occurrence and spread of fire and ensuring the safe and stable operation of the power system.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] An emergency power outage control cabinet comprises a component cabinet and a battery cabinet, wherein a split assembly is arranged inside the battery cabinet, a trigger mechanism is plugged into the bottom of the split assembly, and a tank body is connected to the top of the battery cabinet;

[0009] The splitting assembly includes a guide member, and a guide hole is formed through the top of the guide member;

[0010] The trigger mechanism includes a trigger push rod inserted into the guide hole, the trigger push rod is sleeved with a first spring located inside the battery cabinet, and the trigger push rod is connected to a top seat and a base located outside the battery cabinet, and a heat-sensitive glass tube is symmetrically arranged between the top seat and the base;

[0011] A trigger mechanism is arranged at the bottom of the tank body, and the trigger mechanism is located at the top of the trigger push rod.

[0012] Furthermore, a nozzle is fixedly connected to the bottom of the tank body, and an inner support frame is fixedly connected to the inner top of the nozzle;

[0013] The trigger mechanism comprises a guide column inserted on the inner support frame, a sealing disk is connected to the top of the guide column, and a second spring and a second retaining ring are sleeved on the guide column.

[0014] Furthermore, an umbrella cap is connected to the bottom of the guide column, and the axes of the umbrella cap and the trigger push rod are on the same straight line.

[0015] Furthermore, a first retaining ring is sleeved on the trigger push rod, and the first retaining ring is located above the first spring.

[0016] Furthermore, a through hole is formed through the upper end surface of the top seat, and connecting holes are formed symmetrically through the top of the top seat. A socket is provided on the top of the base, and the bottom end of the trigger push rod is inserted into the socket.

[0017] Furthermore, a first limiting ring is symmetrically arranged at the bottom of the top seat, and a second limiting ring corresponding to the first limiting ring is arranged at the top of the base.

[0018] Furthermore, baffles are fixedly connected to both sides of the guide member, a fixing plate is fixedly connected to the bottom side of the baffle, and fixing holes are formed on the fixing plate at equal intervals along the length direction thereof.

[0019] Furthermore, a connecting seat is provided on the top of the battery cabinet, and a limiting hole is provided through the bottom of the battery cabinet.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] By setting up a split component inside the battery cabinet and equipping it with a trigger mechanism, the utility model realizes automatic fire extinguishing when the temperature rises abnormally and causes the heat-sensitive glass tube to break. This design directly responds to the fire risk that the battery cabinet mentioned in the background technology may cause under extreme temperature conditions. By quickly deploying dry powder to cover the battery, the probability of fire is reduced, thereby effectively avoiding possible serious physical losses and safety accidents.

[0022] The invention ensures the high efficiency and reliability of the fire extinguishing mechanism by carefully designing and arranging key components such as guides, trigger push rods, springs, etc. This mechanical triggering method does not rely on an external power source, ensuring rapid response even in the event of a complete power outage, which solves the problem of response delay that may exist in the prior art that relies on an external fire protection system and increases the self-protection capability of the power system.

[0023] Through the tightly integrated design, the emergency power outage control cabinet of the utility model not only improves the safety of the battery cabinet, but also facilitates the maintenance and management of the power system. In particular, the preset connection seat and limit hole make the installation, inspection and maintenance of the battery cabinet more convenient, further improving the stability and reliability of the overall system.
