[0027] Please refer to Figure 1 The embodiment of the utility model provides a fire extinguishing device, including a fire extinguishing agent storage component 1, a fire extinguishing agent injection component 2, a first pipeline 3, a second pipeline 4 and a third pipeline 5, wherein the two ends of the first pipeline 3 are respectively connected to the fire extinguishing agent storage component 1 and the fire extinguishing agent injection component 2, the first pipeline 3 is provided with a solenoid valve 31, the two ends of the second pipeline 4 are respectively connected to the fire extinguishing agent storage component 1 and the fire extinguishing agent injection component 2, the second pipeline 4 is provided with a first manual valve 41, one end of the third pipeline 5 is connected to the fire extinguishing agent storage component 1, and the other end of the third pipeline 5 is provided with a temperature control nozzle 51.

[0028] Specifically, the solenoid valve 31 and the first manual valve 41 are both normally closed. The temperature control nozzle 51 can be a sprinkler nozzle. When the fire causes the ambient temperature to rise to a predetermined temperature range, the sprinkler nozzle will automatically rupture under the action of heat, causing the fire extinguishing agent to spray out. The fire extinguishing agent storage component 1 can store fire extinguishing agent. When the first pipeline 3 or the second pipeline 4 is connected, the fire extinguishing agent can be sprayed from the fire extinguishing agent spraying component 2 through the pipeline. When the temperature control nozzle 51 ruptures, the fire extinguishing agent can be sprayed from the temperature control nozzle 51 through the third pipeline 5.

[0029] In this embodiment, by connecting the two ends of the first pipeline 3 to the fire extinguishing agent storage assembly 1 and the fire extinguishing agent injection assembly 2 respectively, and providing an electromagnetic valve 31 on the first pipeline 3, under normal power supply conditions, the electromagnetic valve 31 can be opened to make the first pipeline 3 conductive to achieve fire extinguishing; by connecting the two ends of the second pipeline 4 to the fire extinguishing agent storage assembly 1 and the fire extinguishing agent injection assembly 2 respectively, and providing a first manual valve 41 on the second pipeline 4, under normal power supply or power failure conditions, the first manual valve 41 can be manually opened to make the second pipeline 4 conductive to achieve fire extinguishing; by connecting one end of the third pipeline 5 to the fire extinguishing agent storage assembly 1, and providing a temperature-controlled nozzle 51 on the other end of the third pipeline 5, under normal power supply or power failure conditions, the temperature-controlled nozzle 51 can automatically rupture to allow the fire extinguishing agent to be sprayed from the temperature-controlled nozzle 51 to achieve fire extinguishing. In this way, even if the power supply circuit of the fire extinguishing device is disconnected, the fire can still be extinguished by manually opening the first manual valve 41 or the automatic rupture of the temperature-controlled nozzle 51, thereby avoiding the situation where the solenoid valve 31 is powered off and cannot be opened in time, resulting in a fire, thereby reducing the risk of fire; in addition, the solenoid valve 31 can automatically extinguish the fire when there is power, the first manual valve 41 can realize manual fire extinguishing with or without power, and the temperature-controlled nozzle 51 can realize automatic fire extinguishing with or without power, that is, whether there is power or not, the fire extinguishing agent can be controlled to be sprayed in at least two ways to adapt to different fire situations, so as to make the fire extinguishing more timely and effective.

[0030] Optionally, see Figure 1 The fire extinguishing agent storage assembly 1 includes a first container 11 and a fourth pipe 12. The first container 11 is used to store the fire extinguishing agent. One end of the fourth pipe 12 is connected to the first container 11, and the other end of the fourth pipe 12 is respectively connected to the first pipe 3, the second pipe 4 and the third pipe 5.

[0031] In this embodiment, the fire extinguishing agent storage component 1 is set as a first container 11 and a fourth pipe 12, and one end of the fourth pipe 12 is connected to the first container 11, and the other end of the fourth pipe 12 is respectively connected to the first pipe 3, the second pipe 4 and the third pipe 5, so that the first pipe 3, the second pipe 4 and the third pipe 5 are connected in parallel. When the fire extinguishing agent in the first container 11 flows out through the fourth pipe 12, the fire extinguishing agent can be diverted through the first pipe 3, the second pipe 4 and the third pipe 5, thereby realizing multi-channel injection of fire extinguishing agent and improving the timeliness and efficiency of fire extinguishing.

[0032] Optionally, see Figure 1 The fire extinguishing agent storage assembly 1 also includes a second manual valve 13 arranged on the fourth pipeline 12.

[0033] Specifically, the second manual valve 13 is of a normally open type.

[0034] In this embodiment, by providing the second manual valve 13 on the fourth pipeline 12, when the fire is extinguished, the second manual valve 13 can be manually closed to stop the injection of the fire extinguishing agent, thereby avoiding the waste of the fire extinguishing agent.

[0035] Optionally, see Figure 1 The fire extinguishing agent injection assembly 2 includes a normally open nozzle 21 and a fifth pipe 22. The normally open nozzle 21 is used to inject the fire extinguishing agent. One end of the fifth pipe 22 is connected to the normally open nozzle 21, and the other end of the fifth pipe 22 is respectively connected to the first pipe 3 and the second pipe 4.

[0036] In this embodiment, the fire extinguishing agent injection assembly 2 is set to a normally open nozzle 21 and a fifth pipe 22, and one end of the fifth pipe 22 is connected to the normally open nozzle 21, and the other end of the fifth pipe 22 is respectively connected to the first pipe 3 and the second pipe 4, so that the first pipe 3 and the second pipe 4 are connected in parallel with the fifth pipe 22. After the fire extinguishing agent flows out through the first pipe 3 and the second pipe 4 respectively, it can flow into the fifth pipe 22 together and be sprayed out through the normally open nozzle 21 together. Only a single normally open nozzle 21 is used to spray the fire extinguishing agent in the first pipe 3 and the second pipe 4, which is beneficial to saving the number of normally open nozzles 21.

[0037] Optionally, see Figure 1 , the solenoid valve 31 is a manual reset solenoid valve.

[0038] It should be noted that the manual reset solenoid valve is different from the general solenoid valve 31. The general solenoid valve 31 is automatically switched by turning the power on and off, while the manual reset solenoid valve will not close without manual reset once it is electrically opened, and can only be reset manually.

[0039] In this embodiment, by setting the solenoid valve 31 as a manual reset solenoid valve, it is possible to prevent the solenoid valve 31 from automatically closing due to power failure after opening, thereby ensuring that the fire extinguishing agent pipeline remains unobstructed and continuous fire extinguishing is performed.

[0040] Optionally, see Figure 1 The fire extinguishing device further comprises a temperature measuring device 6 and a control device 7, and the control device 7 is electrically connected to the temperature measuring device 6 and the manual reset solenoid valve respectively.

[0041] It can be understood that the temperature measuring device 6 is used to detect the ambient temperature, such as the temperature of the internal environment or the external environment of the power distribution cabinet 8.

[0042] In this embodiment, through the temperature measuring device 6 and the control device 7, when the temperature measuring device 6 detects that the ambient temperature reaches the preset fire extinguishing temperature, the control device 7 controls the manual reset solenoid valve 31 to open, so as to achieve rapid fire extinguishing.

[0043] Optionally, the fire extinguishing device also includes an alarm device, which is electrically connected to the control device 7. In this arrangement, when the temperature measuring device 6 detects that the ambient temperature reaches a preset fire extinguishing temperature, the control device 7 controls the alarm device to alarm to remind personnel to check and eliminate the fault.

[0044] In a power distribution room, there are usually multiple power distribution cabinets 8. When a fire occurs, only one of the power distribution cabinets 8 may catch fire. However, the traditional installation method of the fire extinguishing device in the power distribution room is usually to install it on the top of the power distribution room. The fire extinguishing device will only start to extinguish the fire when the ambient temperature of the entire power distribution room reaches the preset fire extinguishing temperature. However, before the ambient temperature of the entire power distribution room reaches the preset fire extinguishing temperature, the power distribution cabinet 8 that caught fire may have already reached the preset fire extinguishing temperature. Therefore, the traditional installation method of the fire extinguishing device is prone to untimely fire extinguishing, which greatly delays the fire extinguishing time and causes fires.

[0045] In view of this, please refer to Figure 2 The embodiment of the utility model further provides a fire extinguishing system, comprising a plurality of distribution cabinets 8 and a plurality of fire extinguishing devices as described above, wherein the plurality of fire extinguishing devices are respectively arranged in the plurality of distribution cabinets 8 .

[0046] It should be noted that the above-mentioned fire extinguishing system can be installed in a power distribution room.

[0047] In this embodiment, by providing multiple fire extinguishing devices, and the multiple fire extinguishing devices are respectively provided in multiple distribution cabinets 8, point-to-point detection and point-to-point fire extinguishing of the distribution cabinet 8 can be achieved, and the fire extinguishing temperature can be detected earlier, making the fire extinguishing more timely and reducing the occurrence of fire.

[0048] Optionally, see Figure 2 The normally open nozzle 21 and the temperature control nozzle 51 are respectively arranged inside the power distribution cabinet 8, and the fire extinguishing agent storage component 1, the first pipeline 3, the second pipeline 4 and the third pipeline 5 are respectively arranged outside the power distribution cabinet 8.

[0049] In this embodiment, for each component of the fire extinguishing device, only the normally open nozzle 21 and the temperature control nozzle 51 are arranged inside the distribution cabinet 8, avoiding the fire extinguishing device being completely arranged inside the distribution cabinet 8, reducing the congestion in the distribution cabinet 8, and further reducing the probability of fire in the distribution cabinet 8.

[0050] Optionally, see Figure 3 The power distribution cabinet 8 has two installation inner walls 81 arranged opposite to each other, and the normally open nozzle 21 and the temperature control nozzle 51 are respectively installed on the two installation inner walls 81.

[0051] In this embodiment, the normally open nozzle 21 and the temperature-controlled nozzle 51 are separately arranged on two opposite inner installation walls 81 of the distribution cabinet 8, that is, when extinguishing a fire, the normally open nozzle 21 and the temperature-controlled nozzle 51 can extinguish the internal structure of the distribution cabinet 8 from two directions respectively, and the fire extinguishing agent spray coverage is higher, which is beneficial to improving the fire extinguishing efficiency.

[0052] Optionally, see Figure 3 The temperature measuring device 6 is installed on the inner top wall of the power distribution cabinet 8.

[0053] In this embodiment, the temperature measuring device 6 is arranged on the inner top wall of the power distribution cabinet 8 so as to detect the fire extinguishing temperature as early as possible.

[0054] Optionally, see Figure 3 A push rod linear motor 9 is installed on the inner top wall of the power distribution cabinet 8, and the axial direction of the push rod linear motor 9 is parallel to the length direction of the power distribution cabinet 8. The temperature measuring device 6 is arranged at the output end of the push rod linear motor 9, and the temperature measuring device 6 is installed on the inner top wall of the power distribution cabinet 8 through the push rod linear motor 9.

[0055] It should be noted that the length direction of the power distribution cabinet 8 is the length direction of the power distribution cabinet 8 in the horizontal projection, that is, Figure 2 and Figure 3 The Y-axis direction is shown.

[0056] The traditional installation method of the temperature measuring device 6 is often a fixed installation method. When the temperature measuring device 6 detects the temperature in the power distribution cabinet 8, if a fire occurs in an area far away from the temperature measuring device 6, the temperature measuring device 6 may also be difficult to detect as early as possible. Therefore, in this embodiment, by setting the temperature measuring device 6 at the output end of the push rod linear motor 9, the push rod linear motor 9 can drive the temperature measuring device 6 to reciprocate along the length direction relative to the power distribution cabinet 8 when it is in motion, so as to cover as many areas of the power distribution cabinet 8 as possible, detect the fire extinguishing temperature as early as possible, and further improve the timeliness of fire extinguishing.
