Description

Technical Field

[0001] This utility model relates to the field of fire prevention technology for power distribution rooms, specifically to an early detection and automatic fire extinguishing device for power distribution room fires. Background Technology

[0002] As the core hub of the power system, the power distribution room undertakes the critical tasks of power distribution, conversion, and control. Its internal equipment is densely packed, its electrical wiring complex, and its operating environment is characterized by high voltage, high current, and strong electromagnetic interference. However, due to equipment aging, overload operation, poor contact, insulation damage, or external factors (such as lightning strikes or small animal intrusion), power distribution rooms are highly susceptible to fires. These fires spread rapidly and are highly concealed; once out of control, they can lead to widespread power outages, equipment damage, and even casualties. Therefore, automatic fire extinguishing devices are needed. Existing automatic fire extinguishing devices for power distribution rooms usually consist of smoke sensors combined with water pipes and sprinkler systems. After detecting fire smoke, the sprinkler system sprays high-pressure atomized water droplets to cool the room and smother the fire. However, power distribution rooms contain a large number of electronic components. Using traditional high-pressure atomized water droplets for fire extinguishing can damage these electronic components. Furthermore, if a fire starts in a small area in the early stages, the entire room will be extinguished, resulting in unnecessary losses.

[0003] Therefore, it is necessary to provide a new early detection and automatic fire extinguishing device for power distribution rooms to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an early detection and automatic fire extinguishing device for power distribution room fires.

[0005] The early detection and automatic fire extinguishing device for power distribution rooms provided by this utility model includes: Storage cabinets, with multiple sets of storage cabinets, and valves installed on the top of each set of storage cabinets; The storage tanks are placed inside multiple storage cabinets. The storage tanks contain heptafluoropropane. The top of each storage tank is fixedly connected to a connecting pipe. The top of each storage cabinet has a through hole. The connecting pipes pass through the through hole and are fixedly connected to a valve. The transmission pipes are fixedly connected to the top of multiple valves. There are multiple sets of transmission pipes, which are connected in a horizontal and vertical mesh. The multiple sets of transmission pipes are installed in different areas of the room and are independent of each other.

[0006] Preferably, each of the multiple storage cabinets has an opening on one side, a hinge is fixedly connected to one side of each opening, and a cabinet door is fixedly connected to one side of each hinge, allowing for easy replacement of the storage tanks through the cabinet doors.

[0007] Preferably, each of the cabinet doors has an observation window on its top, and each of the connecting pipes has a flow meter installed on one side, which can display the amount of heptafluoropropane.

[0008] Preferably, a fixing plate is provided at the center of each of the multiple sets of transmission tubes, and threaded holes are provided around the perimeter of each of the multiple sets of fixing plates. The first fixing bolt is threaded into the interior of each of the multiple sets of threaded holes. The smoke sensor can be fixed in position by the fixing plate and the first fixing bolt.

[0009] Preferably, each of the multiple fixed plates has a smoke sensor fixedly connected to its bottom, and the smoke sensor can be used to monitor for fire.

[0010] Preferably, each connection point of the multiple sets of transmission pipes is equipped with a spraying device, which can spray heptafluoropropane for fire extinguishing.

[0011] Preferably, a fixing sleeve is fitted at the center of each of the multiple sets of transmission tubes, and through holes are opened on both sides of each of the multiple sets of fixing sleeves. A second fixing bolt is threaded into the interior of each of the multiple sets of through holes. The position of the transmission tube can be fixed by the fixing sleeve and the second fixing bolt.

[0012] Preferably, the spraying device and the smoke sensor are electrically connected via wires and valves, and multiple sets of electronic components can be connected via the wires. Compared with related technologies, the early detection and automatic fire extinguishing device for power distribution rooms provided by this utility model has the following beneficial effects: This utility model provides an early detection and automatic fire extinguishing device for power distribution room fires; This invention can store heptafluoropropane in separate storage tanks. When monitoring the power distribution room, the storage tanks containing heptafluoropropane can be manually placed into the storage cabinet, and the top of the storage tank can be fixed to the connecting pipe. The flow of heptafluoropropane can be controlled by the valve at the top of the connecting pipe. By installing the storage cabinets in different areas of the power distribution room, the automatic fire extinguishing devices for different areas can be realized by storing heptafluoropropane in separate storage tanks. This invention utilizes a transmission pipe in conjunction with a spraying device to extinguish fires in different areas of a power distribution room. When a fire breaks out in a portion of the room, a smoke sensor monitors the smoke and then controls a valve to open, allowing heptafluoropropane stored in the storage pipe to flow into the transmission pipe. The heptafluoropropane is then transported through a mesh-like transmission pipe to multiple spraying devices, which are then controlled to perform fire extinguishing operations. During fire suppression, the multiple automatic fire extinguishing devices operate independently, preventing the entire power distribution room from being sprayed, thus achieving fire suppression in different areas of the power distribution room.

[0017] It should be noted that when monitoring the power distribution room, the storage tank 16 containing heptafluoropropane can be manually placed in the storage cabinet 1, and the top of the storage tank 16 can be fixed to the connecting pipe 15. The flow of heptafluoropropane can be controlled by the valve 2 at the top of the connecting pipe 15. By installing the storage cabinet 1 in different areas of the power distribution room, the storage tanks can store heptafluoropropane separately to form automatic fire extinguishing devices for different areas. After a fire occurs in a part of the power distribution room, the smoke sensor 10 can detect the fire smoke, and then control the valve 2 to open so that the heptafluoropropane stored in the storage tank 16 can flow to the transmission pipe 6. The heptafluoropropane is then transmitted to multiple sets of spraying devices 7 through the mesh transmission pipe 6, and the spraying devices 7 can be controlled to spray and extinguish the fire. When extinguishing a fire in a fire area, the multiple sets of automatic fire extinguishing devices are independent of each other, so they will not spray and extinguish the fire in the entire power distribution room, thus achieving fire extinguishing in different areas of the power distribution room.

[0018] In the embodiments of this utility model, please refer to Figure 1 and Figure 4 Each of the multiple storage cabinets 1 has an opening on one side, and each of the multiple openings is fixedly connected to a hinge 3 on one side.

The flow meter 14 can display the amount of heptafluoropropane.

[0020] In the embodiments of this utility model, please refer to Figure 1 and Figure 4 Each of the multiple sets of transmission tubes 6 has a fixed plate 8 at its center. Each of the multiple sets of fixed plates 8 has threaded holes around its perimeter. Each of the multiple sets of threaded holes is threaded with a first fixing bolt 9. The smoke sensor 10 can be fixed in position by the fixed plate 8 and the first fixing bolt 9.

[0021] In the embodiments of this utility model, please refer to Figure 1 and Figure 4 Each of the multiple fixed plates 8 has a smoke sensor 10 fixedly connected to its bottom, and the smoke sensor 10 can be used to monitor for fire.

[0022] In the embodiments of this utility model, please refer to Figure 1 and Figure 4 Each connection point of the multiple sets of transmission pipes 6 is equipped with a spraying device 7, which can spray heptafluoropropane for fire extinguishing.

[0023] In the embodiments of this utility model, please refer to Figure 1and Figure 4 Each of the multiple sets of transmission pipes 6 is fitted with a fixing sleeve 12 at its center. Each of the multiple sets of fixing sleeves 12 has through holes on both sides. Each of the multiple sets of through holes is threaded with a second fixing bolt 13. The fixed sleeves 12 and the second fixing bolts 13 can fix the position of the transmission pipes 6.

[0024] In the embodiments of this utility model, please refer to Figure 1 and Figure 4 The spraying device 7 and the smoke sensor 10 are electrically connected to the valve 2 via wires 11. Multiple sets of electronic components can be connected via the wires 11.

[0025] The working principle of the early detection and automatic fire extinguishing device for power distribution rooms provided by this utility model is as follows: In operation, when monitoring the power distribution room, the storage tank 16 containing heptafluoropropane can be manually placed into the storage cabinet 1. The top of the storage tank 16 is fixed to the connecting pipe 15, and the flow of heptafluoropropane is controlled by the valve 2 at the top of the connecting pipe 15. By installing the storage cabinet 1 in different areas of the power distribution room, the storage tanks can store heptafluoropropane separately to form automatic fire extinguishing devices for different areas. After a fire occurs in a part of the power distribution room, the smoke sensor 10 can detect the fire smoke, and then control the valve 2 to open so that the heptafluoropropane stored in the storage tank 16 can flow to the transmission pipe 6. The heptafluoropropane is then transmitted to multiple sets of spraying devices 7 through the mesh transmission pipe 6, and the spraying devices 7 are controlled to spray and extinguish the fire. When extinguishing a fire in a fire area, the multiple sets of automatic fire extinguishing devices are independent of each other, so they will not spray and extinguish the fire in the entire power distribution room, thus achieving fire extinguishing in different areas of the power distribution room.
