However, as the number of parts inside the cabinet increases and the power of components increases, the heat generated by the whole machine will also increase sharply, which may cause the temperature of the whole machine to soar or even cause a fire. Quantum encryption communication relies on optical fiber for signal transmission. The temperature rise will affect the efficiency and stability of the optical fiber and its transmission signal, so it is necessary to strictly control the temperature change in the cabinet.

[0003] In the existing encrypted communication industry, a fire or environmental management system is usually installed in the main control room, and sensors are used to monitor physical quantities such as smoke, temperature, flame light, and gas composition in the room.

DETAILED DESCRIPTION

[0043] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0044] In some technologies, in the safety protection system of the cabinet, the detection of abnormal temperature changes or fires, signal transmission, and action execution processes all need to rely on electrical energy to transmit signals or energy. Therefore, when the system power is cut off or the line is interrupted, the protection system is in a failed state and cannot provide protection for the cabinet. In order to solve this technical problem, the present application provides a safety protection device for an encrypted communication cabinet. The following describes the structures of the various parts of the safety protection device for the encrypted communication cabinet:

[0045] For example, in the modern encryption communication industry, cabinets are widely used due to their compact structure, rich functions, and large expansion space. However, with the increase in the number of internal parts and the increase in the power of components, the heat generated by the whole machine also increases sharply. When the heat accumulates to a certain extent, it will cause the temperature of the whole machine to soar or even cause a fire, seriously affecting the normal operation of the equipment and the safety of personnel and property. Quantum encryption communication relies on optical fiber for signal transmission, and sudden temperature changes have a great impact on optical fiber and its transmission signals. Therefore, it is necessary to strictly control the temperature changes in the cabinet and suppress the occurrence of fire in the bud.

[0046] In the existing encrypted communication industry, fire protection or environmental management systems are usually only installed in the main control room. The fire protection system mainly uses sensors to monitor physical quantities such as smoke, temperature, flame light, and gas composition in the room. When the above physical quantities reach the set threshold, relevant electrical signals are sent to the fire protection or environmental management system, and then the fire protection system starts to suppress the fire or the environmental management system controls the environment (temperature). There are few temperature detection and fire suppression systems directly targeting the inside of the cabinet, but the high heat of the cabinet is often the source of temperature abnormalities and fires.

[0047] In the existing quantum communication industry, the cabinet security protection system relies on electrical energy to transmit signals or energy for the detection of abnormal temperature changes or fires, signal transmission, and action execution. Therefore, when the system power is cut off or the line is interrupted, the current fire protection or environmental management system cannot work, and the entire protection system is in a failed state.

[0048] Depend on Figure 1 and Figure 2 It can be seen that the present application provides a security protection device for an encrypted communication cabinet, which is applied to a rack 1, and the rack 1 includes: a base 11 and a connecting portion 12, the connecting portion 12 is connected to the base 11, and is relatively arranged along the length direction of the base 11; the connecting portion 12 can be four pillars respectively located at the four corners of the base 11, or can be two vertical surfaces arranged along the length direction of the base 11, which is not limited here; a plurality of clamping portions 121 are relatively arranged on the connecting portion 12; the cabinet 2 is clamped to the connecting portion 12 through the clamping portion 121, and a gap is arranged between the cabinet 2 and the connecting portion 12; including:

[0049] The temperature-sensitive bracket 3 is clamped to the connection part 12 and is arranged on the side of the cabinet 2 away from the base 11. The function of the temperature-sensitive bracket 3 is to support and fix the fire-extinguishing isolation cover 4 under normal circumstances, so that the fire-extinguishing isolation cover is above the cabinet 2. When the temperature rises, the temperature-sensitive bracket 3 plays the role of monitoring the ambient temperature. When the temperature is greater than the first preset temperature, the first preset temperature will be melted and the fire-extinguishing isolation cover 4 will be released. The fire-extinguishing isolation cover 4 automatically falls to the gap due to gravity and completely surrounds the cabinet 2, and then plays the role of monitoring the temperature and performing fire-extinguishing preparatory actions.

[0050] The fire extinguishing isolation cover 4 is arranged on the side of the temperature-sensitive bracket 3 away from the cabinet 2; a plurality of fire extinguishing modules 5 are arranged on the inner side of the fire extinguishing isolation cover 4; the projection of the fire extinguishing isolation cover 4 in the direction close to the base 11 coincides with the gap; the fire extinguishing isolation cover 4 is made of flame-retardant heat-insulating material and is consistent with the outer contour of the cabinet 2. After a fire occurs, the fire extinguishing isolation cover 4 will fall quickly to fully cover the cabinet 2 where the fire occurs, such as Figure 2As shown, while isolating oxygen and suppressing combustion, it also isolates heat to prevent the heat from spreading and causing damage to adjacent cabinets 2, wherein one fire extinguishing isolation cover 4 can only protect one cabinet 2. A plurality of groups of miniature fire extinguishing modules 5 filled with fire extinguishing medium are built into the top of the fire extinguishing isolation cover 4; wherein the temperature-sensitive bracket 3 is located between the gap and the fire extinguishing isolation cover 4, and is used to prevent the fire extinguishing isolation cover 4 from moving in the direction of the gap; it is understandable that there is a certain gap between the cabinet 2 and the connecting portion 12, and when the fire extinguishing isolation cover 4 falls from the temperature-sensitive bracket 3, it can fall to the gap and cover the cabinet 2, thereby performing a fire extinguishing action; wherein the temperature-sensitive bracket 3 is configured as follows: when the ambient temperature of the temperature-sensitive bracket 3 is greater than When the first preset temperature is reached, the temperature-sensitive bracket 3 changes from the first state to the second state; the temperature-sensitive bracket 3 is made of temperature-sensitive metal materials, such as copper, titanium, silver, aluminum, platinum, nickel, etc.; the temperature-sensitive bracket 3 is in the first state before it melts; when the ambient temperature reaches the first preset temperature, the temperature-sensitive bracket 3 melts and changes to the second state; the fire-extinguishing isolation cover 4 is configured as follows: when the temperature-sensitive bracket 3 changes to the second state, the fire-extinguishing isolation cover 4 slides along the connecting portion 12 to the gap to cover the cabinet 2, thereby performing a fire-extinguishing action.

[0051] The safety protection device of the encrypted communication cabinet provided in this application will be placed above each cabinet 2 and placed together with the cabinet in the rack 1. It can realize supervision at the source of dangerous factors and intervene in the early stage of temperature runaway to avoid fire caused by temperature runaway and cause greater losses. Figure 5 As shown, the specific protection method is as follows: when the temperature of the cabinet 2 is normal, the system will not take action, that is, the temperature-sensitive bracket 3 will not melt; when the temperature of the cabinet 2 rises abnormally, the temperature change can be detected at the first time and the fire-fighting preparatory execution action can be taken in time, that is, the temperature-sensitive bracket 3 melts, and the fire-fighting isolation cover 4 falls to the gap to cover the cabinet 2. After the preparatory execution action is automatically executed, if no fire occurs, the system needs to be manually reset, that is, a new temperature-sensitive bracket 3 is taken and installed in the rack 1, and then the fire-fighting isolation cover 4 is placed above the temperature-sensitive bracket 3. If the temperature continues to rise until a fire occurs after the preparatory action is executed, the fire suppression action continues to be executed, that is, the micro gas fire extinguishing module 5 built into the isolation cover is opened to release the fire extinguishing medium, thereby realizing automatic temperature monitoring and fire suppression work, preventing the spread of fire and suppressing the fire in the early stage. Among them, the entire temperature monitoring and fire suppression work does not require the intervention of electricity, avoiding the failure of the power system caused by the phenomenon of fire caused by temperature rise, so that the cabinet 2 cannot be protected.

[0052] Depend on Figure 1 and Figure 2 It can be seen that the connection part 12 is relatively provided with a slide rail 122; the temperature-sensitive bracket 3 is clamped to the connection part 12 through the slide rail 122. The connection part 12 is relatively provided with a slide rail 122, and the temperature-sensitive bracket 3 can be installed in the rack 1 along the slide rail 122, wherein the length of the slide rail 122 extending from the connection part 12 is based on not affecting the fire-extinguishing isolation cover 4 from falling into the gap.

[0053] Depend on Figure 3 It can be known that the temperature-sensitive bracket 3 includes: a plurality of clamping brackets 31, which are connected by connecting rods 32; the clamping bracket 31 has a first connecting rod 311 and a second connecting rod 312 which are parallel to each other, and a third connecting rod 313 is connected to the same end of the first connecting rod 311 and the second connecting rod 312; wherein, by pressing the connecting rod at one end of the temperature-sensitive bracket 3 and the connecting rod at the other end of the temperature-sensitive bracket 3, the temperature-sensitive bracket 3 is clamped to the connecting portion 12. The temperature-sensitive bracket 3 is similar to a concave shape. When installing the temperature-sensitive bracket 3, the distance between the two ends of the temperature-sensitive bracket 3 can be reduced by rotating the brackets on both sides inward, so that the temperature-sensitive bracket 3 is deeply inserted into the rack 1, and the temperature-sensitive bracket 3 is restored to the original state and then clamped into the rack 1. Compared with the method of setting the slide rail 122, the structure of the temperature-sensitive bracket 3 can eliminate the setting of the guide rail, thereby reducing the manufacturing cost and avoiding the influence of the slide rail 122 on the fire extinguishing isolation cover 4 falling into the gap.

[0054] Depend on Figure 4 It can be seen that the fire extinguishing isolation cover 4 has a first surface 41, a second surface 42, a third surface 43, and a fourth surface 44 which are parallel to each other, and also includes a top surface 45; the first surface 41, the third surface 43, the second surface 42, and the fourth surface 44 are sequentially connected and constitute the fire extinguishing isolation cover 4 with the top surface 45. In the embodiment of the present application, the fire extinguishing isolation cover 4 is configured as a rectangular parallelepiped structure without a bottom cover, and the structure of the fire extinguishing isolation cover 4 corresponds to the structure of the cabinet 2, wherein the length, width, and height of the fire extinguishing isolation cover 4 are all greater than the length, width, and height of the cabinet 2, so that when the fire extinguishing isolation cover 4 falls into the gap, the cabinet 2 can be completely covered, thereby preventing oxygen from entering the fire extinguishing isolation cover 4 and preventing the cabinet 2 from burning.

[0055] In this embodiment, the first surface 41, the third surface 43, the second surface 42, the fourth surface 44, and the top surface 45 are all provided with a plurality of the fire extinguishing modules 5. In the embodiment of the present application, the fire extinguishing modules 5 are provided on the first surface 41, the third surface 43, the second surface 42, the fourth surface 44, and the top surface 45 of the fire extinguishing isolation cover 4, which can improve the fire extinguishing efficiency of the cabinet 2 on the one hand, and can realize fire extinguishing from all directions of the cabinet 2 on the other hand, thereby improving the success rate of fire extinguishing.

[0056] In this embodiment, the fire extinguishing module 5 is configured as follows: when the ambient temperature of the fire extinguishing module 5 is greater than a second preset temperature, the fire extinguishing module 5 is turned on; the first preset temperature is less than the second preset temperature. The fire extinguishing module 5 is composed of a temperature-sensitive metal-blocked nozzle 52, which can melt at the second preset temperature, thereby opening the nozzle 52, so that the fire extinguishing medium inside the nozzle 52 is sprayed in time, thereby realizing the function of automatic fire extinguishing.

[0057] Depend on Figure 4 It can be known that the fire extinguishing module 5 includes: a fixed part 51, one side of which is connected to the fire extinguishing isolation cover 4 and is arranged inside the fire extinguishing isolation cover 4; the fixed part 51 is used to realize the connection between the nozzle 52 and the fire extinguishing isolation cover 4; a nozzle 52, which is connected to the other side of the fixed part 51, and a fire extinguishing medium is arranged in the nozzle 52, and the pressure value in the nozzle 52 is greater than the environmental pressure value; the injection end of the nozzle 52 is provided with a temperature-sensitive metal; wherein, when the ambient temperature of the fire extinguishing module 5 is greater than the second preset temperature, the temperature-sensitive metal melts. The nozzle 52 is filled with a fire extinguishing medium and is filled with pressurized gas. When the ambient temperature of the nozzle 52 reaches the second preset temperature, the temperature-sensitive metal arranged at the injection end of the nozzle 52 melts, and the fire extinguishing medium is sprayed outward under the drive of the pressurized gas. At the same time, the spray end of the nozzle 52 is provided with a precise filter screen. After the fire extinguishing medium passes through the filter screen of the nozzle 52, it will form a uniform gas and diffuse evenly inside the fire extinguishing isolation cover 4, so that the cabinet 2 on fire can be extinguished in all directions.

[0058] Depend on Figure 4 It can be seen that a handle portion 46 is provided on the outside of the fire extinguishing isolation cover 4, which is relatively arranged along the length direction of the fire extinguishing isolation cover 4; and a heat-resistant sleeve is provided on the handle portion 46. It is understandable that after the fire extinguishing isolation cover 4 is used for fire extinguishing, the surface temperature of the fire extinguishing isolation cover 4 is relatively high. In order to prevent maintenance personnel from being scalded when taking the fire extinguishing isolation cover 4, in the embodiment of the present application, a handle portion 46 is provided on the outside of the fire extinguishing isolation cover 4, and the heat-resistant sleeve is provided on the handle portion 46, which further prevents the risk of maintenance personnel being scalded.

[0059] Depend on Figure 1 and Figure 2 It can be seen that the device also includes: an alarm device 6, which is arranged on the side of the connecting part 12 away from the base 11; and is configured to: when the temperature-sensitive bracket 3 changes from the first state to the second state, the alarm device 6 emits a buzzing sound. It can be understood that when the temperature-sensitive bracket 3 changes from the first state to the second state, that is, when the fire-extinguishing isolation cover 4 falls into the gap, the alarm device 6 will emit a buzzing sound to remind maintenance personnel to check the operation of the cabinet 2 as soon as possible to prevent the cabinet 2 from catching fire as much as possible. Among them, the triggering of the alarm device 6 can be obtained by a distance sensor or other device to obtain whether the fire-extinguishing isolation cover 4 is displaced, so that the alarm device 6 emits a buzzing sound, which is not limited here.

[0060] Depend on Figure 1 and Figure 2 It can be seen that the device also includes: an early warning device 7, which is arranged on the side of the connecting part 12 away from the base 11; the early warning device 7 is connected to the setting device in communication, and the setting device is an electronic device capable of receiving information; the early warning device 7 is configured to send an early warning message to the setting device when the temperature-sensitive bracket 3 changes from the first state to the second state. When the temperature-sensitive bracket 3 changes from the first state to the second state, that is, when the fire-extinguishing isolation cover 4 falls into the gap, the early warning device 7 will send an early warning message to the setting device to remind the maintenance personnel to check the operation of the cabinet 2 as soon as possible and prevent the cabinet 2 from catching fire as much as possible. Among them, the triggering of the early warning device 7 can obtain whether the fire-extinguishing isolation cover 4 is displaced through devices such as distance sensors, so that the early warning device 7 sends an early warning message to the setting device, which is not limited here. It is understandable that when there is no maintenance personnel around the cabinet 2, the alarm device 6 will not play a reminder role. The setting of the early warning device 7 can remotely remind the maintenance personnel, so that the maintenance personnel can deal with the cabinet 2 as soon as possible. Among them, the early warning information can also include the location of the cabinet 2, such as the cabinet 2 on fire is located in the first rack 1, so as to improve the efficiency of the maintenance personnel in finding the cabinet 2 on fire.
