Description

Technical Field

[0001] The present application relates to the field of fire emergency technology, and in particular to a fire emergency power supply box. Background Art

[0002] Safety and aesthetics have always been two important considerations in modern building design. Especially in the field of fire emergency, emergency power boxes are key equipment to ensure power supply in emergency situations such as fires. Their stability and reliability are crucial to the safety of maintenance personnel and the normal operation of equipment.

[0003] At present, the emergency power boxes in many buildings are designed to be installed inside the walls. On the one hand, this design can improve the protection of the power box and prevent external physical damage and man-made damage; on the other hand, by hiding the power box inside the wall, it also greatly improves the overall aesthetics of the building.

[0004] However, in actual use, when a fire occurs in a building, the fire will spread rapidly and generate a large amount of heat. Since the internal cavity of the wall and the emergency power supply box are usually not equipped with independent ventilation mechanisms, and for the convenience of operation, an operating door is usually provided on the wall, so that external heat can easily penetrate through the operating door on the wall and the gaps between them, causing the temperature of the internal cavity to rise rapidly. The high temperature environment is extremely unfavorable for electronic components and batteries inside the power box. They may fail or be damaged due to overheating, thereby affecting the service life and reliability of the emergency power supply box.

[0005] Emergency power boxes usually have the important task of providing emergency power supply in fires. If the power box fails too quickly due to excessive internal temperature, it will not be able to provide the necessary power support for the fire emergency lights and other key equipment in the corridor at the critical moment, which will seriously affect the evacuation of personnel and fire fighting.

[0006] In view of the above problems, a fire emergency power supply box is now designed. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] An embodiment of the present application provides a fire emergency power supply box, which can solve the problem in the related art that the internal cavity of the wall and the emergency power supply box are usually not provided with an independent ventilation mechanism, and the external heat can easily invade the internal cavity, causing the temperature of the cavity to rise rapidly, affecting the service life and reliability of the emergency power supply box.

[0030] See also Figure 1-Figure 3 A fire emergency power supply box includes: a wall 1, an isolation shell 2 and a power supply box body 3, the wall 1 is provided with a chamber 4 for accommodating the isolation shell 2, and the isolation shell 2 is provided with a fixing frame 5 for installing the power supply box body 3; an opening is provided on one side of the isolation shell 2, and a partition door 6 is embedded on the wall 1, and the partition door 6 is used to close the opening of the isolation shell 2, and a heat dissipation duct 7 is provided on the other side of the isolation shell 2, and the heat dissipation duct 7 has a heat dissipation cavity 8 for hot air discharge and a return air cavity 9 for external gas to enter, and a heat sink 10 is provided on the side of the power supply box body 3 close to the heat dissipation duct 7.

[0031] In actual use, the power box body 3 is installed inside the isolation shell 2 through the fixing frame 5 to ensure its stability during operation.

[0032] An opening is provided on one side of the isolation shell 2, and the opening is closed by a partition door 6 embedded in the wall 1. The partition door 6 can tightly close the opening to prevent external heat and flames from directly invading the interior of the isolation shell 2, thereby protecting the power box body 3 from damage by high temperature and flames.

[0033] The heat dissipation duct 7 contains two cavities: a heat dissipation cavity 8 and an air return cavity 9, wherein the heat dissipation cavity 8 is used to discharge the hot air generated by the power box body 3. When the power box body 3 is working, the heat sink 10 close to the side of the heat dissipation duct 7 will conduct the generated heat to the heat dissipation cavity 8. The design of the heat dissipation cavity 8 enables the hot air to be smoothly guided from the surrounding of the power box body 3 and discharged into the external environment.

[0034] The return air chamber 9 is used for the entry of external air. Through the return air chamber 9, fresh air from the outside is introduced into the interior of the isolation shell 2, forming convection with the hot air in the heat dissipation chamber 8, thereby helping the power box body 3 to dissipate heat better. This convection cycle design can effectively reduce the temperature of the power box body 3 and keep it within the normal operating temperature range.

[0035] The heat generated by the power box body 3 can be effectively dissipated into the isolation housing 2 through the heat sink 10, and the heat sink 10 can quickly absorb and conduct the heat.

[0036] In emergency situations such as fire, the external ambient temperature will rise rapidly. However, due to the closed nature of the isolation shell 2, the heat sink 10 quickly absorbs and conducts the heat generated by the power box body 3. The efficient heat dissipation mechanism of the heat dissipation duct 7 allows the power box body 3 to be maintained in a relatively low temperature range, ensuring that the power box body 3 can still work normally in an emergency and provide necessary power support for fire-fighting equipment and other key equipment.

[0037] In summary, the fire emergency power supply box achieves stable operation in high temperature environment through reasonable installation layout and efficient heat dissipation mechanism design, which improves its reliability and dependability in emergency situations such as fire.

[0038] In this embodiment, the power box body 3 includes a main circuit breaker: the main circuit breaker is the core control part of the power box, which is responsible for controlling the total power supply of the distribution box and ensuring the safe operation of the circuit. When an abnormality occurs in the circuit, the main circuit breaker can quickly cut off the power supply to prevent fire or other accidents; distribution module: the distribution module is the power distribution control part in the power box, which is responsible for dividing the power supply into several parts and performing power distribution control as needed; power module: the power module is an important part of the fire emergency power box, which is responsible for providing stable power support for the entire system. The power module usually includes an AC power supply and a backup power supply to ensure that the system can still operate normally for a period of time when the city power is interrupted, providing power guarantee for emergency situations such as fire extinguishing and fire prevention. Monitoring and alarm system: The fire emergency power box is also equipped with a monitoring and alarm system, which can monitor the environmental parameters such as temperature and humidity inside the power box in real time, as well as the working status of electrical components. When an abnormality occurs, the system will automatically send an alarm signal to remind personnel to deal with it in time to prevent accidents. This is a prior art and will not be repeated here.

[0039] Specifically, Figure 1 and Figure 7 As shown, the isolation shell 2 in this embodiment is rectangular and hollow inside, the fixing frame 5 is arranged inside the isolation shell 2, and the fixing frame 5 is separated from the isolation shell 2 to form an installation cavity and a gas flow cavity, and the power box body 3 is arranged inside the installation cavity.

[0040] The installation cavity is an area for placing the power box body 3, which ensures that the power box body 3 is stably supported and protected inside the isolation shell 2, and also facilitates installation and maintenance work.

[0041] The gas flow cavity is located outside the installation cavity and is the space inside the isolation housing 2 except the installation cavity. The main function of this area is to allow the gas to flow freely and provide support for the heat dissipation of the power box body 3.

[0042] When the power box body 3 generates heat during operation, the heat sink 10 quickly absorbs the heat generated by the power box body 3 and conducts it to the gas flow cavity, and guides the heat from the gas flow cavity through the heat dissipation duct 7 and discharges it to the external environment, completing the heat exchange.

[0043] In this embodiment, the gas flow chamber is provided with a first wiring port for connecting a wire, and the power box body 3 is provided with a plurality of second wiring ports.

[0044] Through wiring port one and wiring port two, external wires are allowed to enter the gas flow chamber through wiring port one, and then be connected to the power box body 3 through wiring port two. Through reasonable layout and design, wiring port one and wiring port two can conveniently connect various external devices to meet different usage requirements.

[0045] The wire is introduced into the wiring port 1 on the gas flow chamber and connected through the wiring port 2 on the power box body 3, which facilitates the connection and management of the wire. At the same time, since both the wiring port 1 and the wiring port 2 are located inside the gas flow chamber, the wire will not be affected by high temperature during the connection process, further improving the safety of the connection.

[0046] In this embodiment, the fixing frame 5 includes two groups of cross beams and a plurality of steel plates. The two groups of cross beams are arranged on the upper and lower sides of the interior of the isolation shell 2, and the plurality of steel plates are arranged between the two groups of cross beams. The steel plate can be designed in an I-shape. The other side of the heat sink 10 passes through the steel plate and extends to the interior of the gas flow cavity, wherein the installation cavity and the gas flow cavity are not closed, and the gas can flow.

[0047] The fixing frame 5 is composed of two groups of cross beams and a number of steel plates. The two groups of cross beams are respectively arranged on the upper and lower sides of the isolation shell 2 to provide a stable support for the power box body 3. The steel plate is vertically arranged between the two groups of cross beams to form a structure similar to an "I" shape, which not only enhances the strength of the fixing frame 5, but also facilitates the arrangement of other components such as the heat sink 10.

[0048] The heat sink 10 is arranged on one side of the power box body 3, and the other side thereof passes through the steel plate and extends into the gas flow cavity. This design allows the heat generated by the power box body 3 during operation to be quickly conducted to the gas flow cavity through the heat sink 10.

[0049] The gas flow cavity is an important component inside the isolation shell 2. It is not closed to the installation cavity, allowing gas to flow, so that the heat generated by the power box body 3 can be quickly transferred to the gas flow cavity through the heat sink 10 and exchanged with the external cold air.

[0050] Preferably, Figure 2 As shown, the isolation shell 2 in this embodiment includes an outer layer 21, a middle layer 22 and an inner layer 23 arranged in sequence. The outer layer 21 is a galvanized steel plate, and is used for corrosion prevention and improving the impact resistance of the power box body 3. The middle layer 22 is an aluminum silicate fiber layer, and is used to prevent heat transfer and improve thermal insulation performance. The inner layer 23 is a stainless steel layer, and is used to maintain the stability of the power box body 3 in a high temperature environment.

[0051] The outer layer 21 is made of galvanized steel sheet, which has excellent anti-corrosion performance and can prevent the outer shell from rusting and being damaged due to long-term exposure to a humid and corrosive environment. In addition, the galvanized steel sheet also has a high impact resistance and can effectively protect the internal power box body 3 from damage caused by external impact.

[0052] The middle layer 22 uses an aluminum silicate fiber layer as a heat insulating material. Aluminum silicate fiber is a high-performance heat insulating material with excellent high temperature resistance, oxidation resistance, good thermal stability, etc. It can effectively prevent heat from being transferred outward from the power box body 3, thereby improving the heat insulating performance of the power box.

[0053] The inner layer 23 is made of a stainless steel layer, which has excellent high temperature resistance and corrosion resistance and can maintain stable performance in a high temperature environment. The design of the inner layer 23 not only improves the high temperature resistance of the power box body 3, but also prevents the internal circuits and components from being corroded and damaged by the external environment.

[0054] Under normal working conditions, the three-layer structure of the isolation shell 2 can effectively prevent external heat from being transferred inward, thereby maintaining the temperature inside the power box body 3 stable. In emergency situations such as fire, even if the external ambient temperature rises rapidly, due to the thermal insulation performance of the isolation shell 2, the temperature inside the power box body 3 can be maintained at a relatively low level.

[0055] As a preferred embodiment, Figure 3 As shown, in this embodiment, a reflective layer 24 is arranged between the middle layer 22 and the inner layer 23. The reflective layer 24 is an aluminized polyester film. The aluminized polyester film is arranged on the side of the stainless steel layer close to the aluminum silicate fiber layer and is used to reflect and absorb thermal radiation.

[0056] The reflective layer 24 is made of aluminum-coated polyester film. This material has excellent reflective properties and can effectively reflect and absorb thermal radiation. When the heat generated by the power box body 3 during operation is conducted to the reflective layer 24 through the aluminum silicate fiber layer, the aluminum-coated polyester film will reflect most of the heat radiation back to the aluminum silicate fiber layer, reducing the transfer of heat to the inner layer 23 and enhancing the thermal insulation performance of the power box.

[0057] Under normal working conditions, the aluminum silicate fiber layer of the middle layer 22 has good thermal insulation properties, and most of the heat is confined inside the aluminum silicate fiber layer, while the aluminum-plated polyester film of the reflective layer 24 can reflect and absorb the thermal radiation, further reducing the transfer of heat to the inner layer 23.

[0058] It should be noted that if Figure 6 As shown, the heat dissipation duct 7 in this embodiment includes a shell 71 and a partition 72, the shell 71 is arranged inside the wall 1, and the two ends of the shell 71 are respectively connected to the gas flow cavity and the outside world, the partition 72 is arranged inside the shell 71, and the partition 72 and the shell 71 are separated to form an upper heat dissipation cavity 8 and a lower return air cavity 9; an exhaust fan 73 is provided at one end of the heat dissipation cavity 8 close to the gas flow cavity and at one end of the return air cavity 9 close to the outside world.

[0059] Inside the shell 71, the partition 72 separates it into two parts: an upper heat dissipation cavity 8 and a lower air return cavity 9. This design enables the air to form an effective circulation when flowing through the heat dissipation duct, thereby improving the heat dissipation efficiency.

[0060] In order to improve the heat dissipation effect, an exhaust fan 73 is provided at one end of the heat dissipation cavity 8 close to the gas flow cavity and at one end of the return air cavity 9 close to the outside. The function of the exhaust fan 73 is to accelerate the heat dissipation process by forced air flow.

[0061] Under normal working conditions, the heat generated by the power box body 3 will first be dissipated into the gas flow cavity through the heat sink 10, and then the hot air will be sucked in by the exhaust fan 73 in the heat dissipation cavity 8 and discharged through the heat dissipation cavity 8; then, the external gas will be sucked into the return air cavity 9, and the gas will enter the gas flow cavity again to provide cooling for the power box body 3.

[0062] Specifically, Figure 5 As shown, the partition door 6 in this embodiment includes an electric push rod 61, a partition plate 62, an insertion strip 63 and a temperature sensor 64. The electric push rod 61 is arranged inside the wall 1, and the partition plate 62 is embedded in the wall 1 and is located above the opening of the isolation shell 2. The piston rod of the electric push rod 61 is connected to the insertion strip 63, and the other end of the insertion strip 63 is inserted into the partition plate 62. The temperature sensor 64 is arranged inside the isolation shell 2.

[0063] Among them, the chamber 4 is provided with a chamber 2 for accommodating the partition plate 62, and a chamber 3 for accommodating the electric push rod 61 and the insert 63 is opened on one side of the chamber 2, and the temperature sensor is electrically connected to the electric push rod 61 and the exhaust fan 73 respectively.

[0064] The temperature sensor 64 is arranged inside the isolation shell 2, and is used to monitor the temperature inside the isolation shell 2 in real time. When the temperature exceeds the preset safety threshold, the temperature sensor 64 will send a signal to the electric push rod 61 to drive it to work, and the electric push rod 61 drives the insert 63 to retract, so that the partition plate 62 slides out of the wall 1, and closes the opening of the isolation shell 2, thereby preventing the entry of flames and harmful gases, and protecting the power box body 3 from damage.

[0065] The temperature sensor 64 is not only connected to the electric push rod 61, but also electrically connected to the exhaust fan 73. When the temperature inside the isolation housing 2 rises, the temperature sensor 64 may trigger the closing of the partition door 6 and send a signal to the exhaust fan 73 to enhance its working intensity and accelerate the heat dissipation process. This linkage mechanism ensures that the power box can maintain a stable operating temperature in a high temperature environment.

[0066] This embodiment also includes a controller, which is electrically connected to the temperature sensor.

[0067] The controller first receives a signal from the temperature sensor 64. The temperature sensor monitors the temperature inside the isolation shell 2 in real time and transmits this data to the controller. The controller compares the received temperature data with a preset safety threshold. When the temperature exceeds the safety threshold, the controller sends a signal to the electric push rod 61 to drive it to work. The electric push rod drives the insert 63 to retract, so that the partition plate 62 slides out of the wall 1 and closes the opening of the isolation shell 2. At the same time, the controller sends a signal to the exhaust fan 73 to increase its working intensity to accelerate the heat dissipation process. If the temperature is extremely high, the controller may command the exhaust fan to run at maximum power.

[0068] The controller also has monitoring and alarm functions. If the temperature inside the power box continues to rise, or if there is a failure in components such as the electric push rod or exhaust fan, the controller can notify relevant personnel through preset alarm methods such as sound and light alarms and remote communication.

[0069] It can be understood that the controller in this embodiment is a programmable logic controller PLC or an embedded controller, which is powered by the mains and ensures that it can continue to operate for a certain period of time when the mains is interrupted through an internal power management system. In addition, it is also powered by the power supply of the power box body 3. This is a prior art and will not be repeated here.

[0070] In this embodiment, the chamber 4 is provided with an operating door, wherein the operating door may be a glass door or a mimic door.

[0071] The operating door provided on the chamber 4 of the fire emergency power supply box can select different types of door panels according to actual needs to ensure the safety and observability of the equipment inside the power supply box.

[0072] The glass door is a transparent or translucent operating door that allows personnel to observe the interior of the chamber 4 through a transparent glass plate without opening the door.

[0073] A mimic door is an operating door with a camouflage function. Its appearance design is coordinated with the surrounding environment or equipment and is not easy to be detected. This design can increase the safety of the power box and prevent unauthorized personnel from accidentally breaking in or maliciously destroying it.

[0074] In another embodiment, considering the fire problem, in order to avoid a fire at the junction of the heat dissipation duct 7 and the external interface, which may cause the inhalation of high-temperature gas, increase the temperature inside the heat dissipation duct 7, and even cause a fire, the external interface of the heat dissipation duct 7 should be set in a relatively safe position, away from potential fire sources and high-temperature areas. For example, the external interface can be set on the top floor of a building, on the side of a building, and inside an elevator shaft.

[0075] At the same time, the interface and the heat dissipation duct 7 should use materials with good high temperature resistance and flame retardancy.

[0076] Furthermore, in this embodiment, fire dampers are provided at the interfaces between the heat dissipation cavity 8 and the return air cavity 9 and the outside.

[0077] When an abnormal increase in external temperature is detected, the fire damper can automatically close, cutting off the connection between the heat dissipation cavity 8 and the return air cavity 9 and the external environment, preventing high-temperature gas from entering the power box.
