Description

Technical Field

[0001] This invention relates to the field of uninterruptible power supply (UPS) technology, and in particular to an UPS device with monitoring and early warning functions. Background Technology

[0002] An uninterruptible power supply (UPS) is an emergency power supply device that can continuously provide stable and uninterrupted power to electrical equipment when the power grid is interrupted or abnormal. The core function of an UPS is to ensure the continuity and stability of power supply.

[0003] Chinese Patent Publication No. CN219499014U discloses an online uninterruptible power supply (UPS) device, relating to the field of UPS technology. The device includes a power supply body with a groove on its outer wall. A copper fin heat sink is fixedly mounted on the inner wall of the groove. A fixing block is fixedly mounted on the inner wall of the groove, horizontally distributed on the outer side of the copper fin heat sink. Symmetrically distributed through holes are located on the outer wall of each fixing block. A support rod is fixedly mounted on the inner wall of each through hole. An exhaust fan is fixedly mounted on the end of the support rod away from the through hole. This application, through the coordinated arrangement of the copper fin heat sink, fixing block, support rod, and exhaust fan, facilitates heat dissipation within the device, preventing excessive heat buildup during prolonged operation. This, in turn, extends the device's lifespan, ensures normal operation, and improves its stability and reliability.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: In the process of using existing uninterruptible power supply equipment, when the internal temperature of the device is too high, the cross-sectional area of ​​the air duct is reduced to increase the air speed and concentrate the heat dissipation of the main heat-generating components, which effectively ensures the cooling effect of the device. However, when the increased air speed passes through the air outlet filter plate, the interaction between the pore resistance of the filter plate itself and the impact effect of the high-speed airflow causes the airflow to form local turbulence at the filter plate, which affects the exhaust efficiency of the device. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that the existing technology has the disadvantage that the increased wind speed causes local turbulence to form at the filter plate when the airflow passes through the air outlet filter plate. To this end, we propose an uninterruptible power supply device with monitoring and early warning function.

[0006] To achieve the above objectives, this application adopts the following technical solution: an uninterruptible power supply (UPS) device with monitoring and early warning functions, comprising: a UPS device body, a main heating element fixedly connected inside the UPS device body, a heat-conducting plate fixedly connected to the outer wall of the main heating element, a first rotating shaft fixedly connected to the top of the heat-conducting plate, a first connecting plate rotatably connected to the top of the first rotating shaft, a second rotating shaft rotatably connected to the top of the first connecting plate, a fixed vertical plate fixedly connected to the top of the second rotating shaft, an infrared sensor fixedly connected to the side of the fixed vertical plate, and a second connecting plate slidably connected to the side of the first connecting plate.

[0008] Preferably, the height of the infrared sensor is lower than the height of the reflector, and the infrared sensor and the reflector are located on the same vertical plane.

[0009] Preferably, the baffle shaft is fixedly connected to the main body of the uninterruptible power supply equipment, and the corrugated connecting plate is used to connect adjacent air duct baffles.

[0010] Preferably, the device motor and the uninterruptible power supply equipment body are fixedly connected, and the connection between the device motor and the motor gear passes through the interior of the air outlet filter plate.

[0016] The technical effects and advantages of this invention are as follows: In this invention, an air duct baffle is provided. When the temperature of the main heating element is too high, the heat-conducting plate expands due to heat. The distance of the expansion is amplified by the lever structure, causing the air duct baffle to tilt, narrowing the air intake duct and accelerating the airflow. Simultaneously, as the air duct baffle tilts, when the infrared sensor detects the reflector, the infrared sensor causes the device motor to run. The device motor drives the transmission gear to rotate through the motor gear, at which point the exhaust fan begins to perform circular motion. The rotation of the exhaust fan not only accelerates the airflow effect of the device, but also causes the air duct to dynamically change, allowing the high-speed airflow to periodically sweep across different positions of the heat source, ensuring that all main heating elements are effectively cooled.

[0021] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0022] According to one embodiment of the present invention, Figures 1 to 9 As shown.

[0023] In existing uninterruptible power supply (UPS) equipment, during long-term operation, when the overall temperature of the internal core components exceeds the safety threshold due to increased load or rising ambient temperature, the airflow speed is increased by reducing the cross-sectional area of ​​the air duct. At this time, the high-speed airflow can accurately focus on the surface and surrounding area of ​​the main heat-generating element 2, and achieve concentrated heat dissipation of the high-heat-generating area by enhancing convective heat transfer efficiency, thereby quickly removing the excess heat generated by the element and effectively maintaining the temperature of the core components of the equipment within the allowable range. However, when the accelerated airflow flows through the outlet filter plate 16 of the device, since the filter plate usually adopts a high-density pore structure to ensure dust prevention, its inherent pore resistance will interact violently with the strong impact effect of the high-speed airflow, resulting in a large number of irregular vortices and turbulent areas on the inner side of the filter plate. These turbulence will significantly increase the pressure drop of the airflow through the filter plate, and on the other hand, cause some airflow to be affected by the resistance. Forced to change flow direction, and even forming backflow at the gap between the filter plate and the air outlet frame, the originally smooth exhaust airflow becomes stagnant in the filter plate area, seriously affecting the exhaust efficiency of the entire heat dissipation system, and thus weakening the concentrated heat dissipation effect achieved by narrowing the air duct and increasing speed. To solve this problem, the present invention incorporates the following design in an uninterruptible power supply (UPS) device with monitoring and early warning function: A UPS device with monitoring and early warning function, comprising: a UPS device body 1, the UPS device body 1 being the core structural assembly of the UPS system responsible for core power supply, power conversion, power protection and operation control functions, and a key part to ensure continuous and stable power supply to the load equipment when the power grid is abnormal; the UPS device body 1 having a main heat-generating element 2 fixedly connected inside, the main heat-generating element 2 including power diodes and IGBTs in the rectifier and inverter. The components include equal-power switching devices, isolation transformers, filter inductors, and other electromagnetic elements. The outer wall of the main heating element 2 is fixedly connected to a heat-conducting plate 3. The heat-conducting plate 3 is made of aluminum-copper alloy, which has excellent thermal conductivity and a high coefficient of thermal expansion, allowing for significant expansion and contraction with temperature changes. It is also lightweight and easy to process, making it suitable as a heat-conducting component requiring mechanical linkage through thermal expansion and contraction. A first rotating shaft 4 is fixedly connected to the top of the heat-conducting plate 3. A first connecting plate 5 is rotatably connected to the top of the first rotating shaft 4. A second rotating shaft 6 is rotatably connected to the top of the first connecting plate 5. A fixed vertical plate 7 is fixedly connected to the top of plate 6. An infrared sensor 8 is fixedly connected to the side of the fixed vertical plate 7. The infrared sensor 8 is an electronic device that can detect and receive infrared rays emitted or reflected by objects and convert the infrared signals into electrical signals. It uses the physical characteristics of infrared rays to achieve functions such as target detection, ranging, temperature measurement, or motion sensing. A second connecting plate 9 is slidably connected to the side of the first connecting plate 5. The first connecting plate 5 and the second connecting plate 9 are connected in a nested manner to enable adaptive adjustment. A third rotating shaft 10 is rotatably connected to the top of the second connecting plate 9.A duct baffle 11 is fixedly connected to the side of the third rotating shaft 10. The duct baffle 11 is used to adjust the size of the duct to meet the cooling requirements of the device at different temperatures. A reflector 12 is fixedly connected to the top of the duct baffle 11. The reflector 12 is an auxiliary device used in conjunction with the infrared sensor 8. Its core function is to enhance the sensor's detection capability for specific areas or targets by reflecting infrared light, thereby optimizing signal transmission efficiency or expanding the detection range. A baffle rotating shaft 13 is movably connected to the other side of the duct baffle 11. A corrugated connecting plate 14 is fixedly connected to the outer wall of the duct baffle 11. The core feature of the corrugated connecting plate 14 is its corrugated surface, which allows it to adaptively adjust its body shape according to the tilt of adjacent duct baffles 11 to meet different needs. An air outlet filter 16 is fixedly connected to one side of the uninterruptible power supply device body 1. A device motor 17 is fixedly connected to the bottom of the air outlet filter 16. The device motor 17 refers to a motor integrated into various devices as a motor. The electric motor, which drives the equipment to complete specific mechanical actions, has the core function of converting electrical energy into mechanical energy to drive the internal components of the equipment, thereby realizing the automated operation or functional adjustment of the device. A motor gear 18 is fixedly connected to the output end of the motor 17. A transmission gear 19 meshes with the top of the motor gear 18. An exhaust fan 20 is fixedly connected to the side of the transmission gear 19. The intake fan 24 and the exhaust fan 20 are a pair of core components working collaboratively in the equipment's heat dissipation system. They work together to achieve air circulation between the inside and outside of the equipment through directional airflow guidance, maintaining a stable temperature. The intake fan 24 draws in cool air from outside the equipment and delivers fresh, low-temperature airflow into the equipment, providing a cooling source for heat dissipation. The exhaust fan 20 exhausts the high-temperature air that has undergone heat exchange inside the equipment to the outside, reducing heat accumulation inside the equipment. A limiting groove 21 is formed inside the transmission gear 19, and an L-shaped limiting block 22 is slidably connected to the inner wall of the limiting groove 21.

[0024] The fixed vertical plate 7 is fixedly connected to the uninterruptible power supply (UPS) equipment body 1, and the included angle between the fixed vertical plate 7 and the UPS equipment body 1 is 90 degrees. The height of the infrared sensor 8 is lower than the height of the reflector plate 12, and the infrared sensor 8 and the reflector plate 12 are located on the same vertical plane. The baffle shaft 13 is fixedly connected to the UPS equipment body 1. The corrugated connecting plate 14 is used to connect adjacent air duct baffles 11. The device motor 17 is fixedly connected to the UPS equipment body 1, and the connection between the device motor 17 and the motor gear 18 passes through the interior of the outlet filter plate 16. The L-shaped limiting block 22 is fixedly connected to the outlet filter plate 16. Four L-shaped limiting blocks 22 are equidistant from the horizontal central axis of the transmission gear 19. The outer walls of the first connecting plate 5 and the second connecting plate 9 are each provided with a guide groove 15, which guides the airflow. When cold air passes through the guide groove 15, it flows along the guide groove 15. The guide groove 15 serves a guiding function. An inlet filter plate 23 is fixedly connected to the other side of the uninterruptible power supply equipment body 1. An inlet fan 24 is fixedly connected to the outer wall of the inlet filter plate 23. The inlet filter plate 23 and the outlet filter plate 16 are... The uninterruptible power supply (UPS) device 1 is a functional component installed at the air inlet and outlet of the ventilation, heat dissipation, or air circulation system to filter air impurities. Its core function is to purify the air, protect the internal components of the equipment, and maintain the system's ventilation efficiency. A luminous alarm 25 is fixedly connected to the top of the UPS device 1. The luminous alarm 25 is a device that transmits warning information by emitting a strong, conspicuous light signal. It is mainly used to warn surrounding personnel or equipment in emergency situations, abnormal conditions, or scenarios requiring attention, indicating potential dangers, malfunctions, or special events. A buzzer 26 is installed on the side of the luminous alarm 25. The buzzer 26 is an electronic sound-emitting device that converts electrical signals into sound signals. It is widely used in various equipment, transmitting information by emitting sounds of specific frequencies to achieve reminder, warning, or interactive feedback functions. The buzzer 26 is fixedly connected to the UPS device 1. A control panel 27 is fixedly connected to the front of the UPS device 1. The control panel 27 is used to adjust the working status of the device. A device support base 28 is fixedly connected to the bottom of the UPS device 1 to ensure the stability of the device.

[0025] When the device is in use, cold air from the outside enters the device under the action of the intake fan 24. The intake filter plate 23 filters the incoming air. The cold air blows over the internal components and then exits the device through the outlet filter plate 16. When the temperature of the main heating element 2 exceeds the preset threshold due to prolonged high-load operation or a sudden rise in ambient temperature, the temperature of the main heating element 2 increases. The heat-conducting plate 3, which is in close contact with the main heating element 2, begins to expand due to heat. At this time, the expanding heat-conducting plate 3 drives the first rotating shaft 4 to rise. When the first rotating shaft 4 rises, the first connecting plate 5 rotates around the second rotating shaft 6. The second rotating shaft 6 slides inside the second connecting plate 9 for adaptive adjustment. At this time, under the action of the third rotating shaft 10 of the second connecting plate 9, the air duct baffle 11 rotates around the baffle rotating shaft 13, causing the air duct baffle 11 to tilt. The adjacent corrugated connecting plates 14 serve as connections. The corrugated connecting plate 14 can adjust its shape according to the tilt of the air duct baffle 11. At this time, the air duct becomes smaller and the generated wind speed becomes faster. The cold air dissipates heat from the main heat-generating element 2. During the tilting of the air duct baffle 11, the position of the reflector 12 changes. When the reflector 12 is identified by the infrared sensor 8, the infrared sensor 8 sends a trigger command to the control unit. The device motor 17, the light alarm 25, and the buzzer 26 start to work. The light alarm 25 and the buzzer 26 serve as an early warning to remind the staff that the device is in a high-temperature state. The device motor 17 drives the motor gear 18 to rotate, and the motor gear 18 drives the transmission gear 19 to rotate. The exhaust fan 20 moves in a circular motion along with the transmission gear 19. During the rotation of the transmission gear 19, the limiting groove 21 and the L-shaped limiting block 22 serve as limiting and supporting functions to ensure the stability of the transmission gear 19 during rotation.

[0026] The device is equipped with a dynamically adjustable duct baffle 11, whose core function is to adjust the duct shape in real time according to the temperature changes inside the device. When the main heating element 2 exceeds the preset threshold due to prolonged high-load operation or a sudden rise in ambient temperature, the heat-conducting plate 3 expands due to heat. The distance of the expansion of the heat-conducting plate 3 is amplified by a lever structure, which includes a first rotating shaft 4, a first connecting plate 5, a second rotating shaft 6, a fixed vertical plate 7, a second connecting plate 9, and a third rotating shaft 10. This, in turn, pushes the duct baffle 11 to tilt. As the tilt angle of the duct baffle 11 gradually increases, the cross-sectional area of ​​the air inlet duct is gradually compressed. According to Bernoulli's principle in fluid mechanics, under the premise that the output air volume of the fan is relatively stable, the contraction of the duct cross-sectional area will significantly increase the velocity of the flowing air. This system quickly removes excess heat generated by the components, achieving concentrated heat dissipation in high-heat areas and effectively maintaining the temperature of the core components within a safe range. Simultaneously, as the air duct baffle 11 tilts, when the infrared sensor 8 detects the reflector 12, it quickly sends a trigger command to the control unit, causing the device motor 17 to run. The device motor 17 drives the transmission gear 19 to rotate via the motor gear 18. At this time, the exhaust fan 20 begins to perform circular motion. The rotation of the exhaust fan 20 not only accelerates the airflow effect of the device, but also causes the air duct to dynamically change, allowing the high-speed airflow to periodically sweep across different positions of the heat source, ensuring that all major heat-generating components 2 can be effectively cooled, completely eliminating the potential heat dissipation dead zones that may exist in traditional fixed air ducts.

[0027] When the main heat-generating element 2 exceeds the threshold due to high load or ambient temperature rise, the thermal expansion characteristics of the heat-conducting plate 3, combined with the lever structure, directly push the air duct baffle 11 to tilt, actively compressing the air intake cross-sectional area. The airflow speed increases significantly as the cross-sectional area decreases, quickly focusing on the high-heat-generating area and forming a directional strong airflow. This solves the problem of insufficient heat dissipation in traditional fixed air ducts when components suddenly overheat. The exhaust fan 20, triggered by the infrared sensor 8, performs circular motion, not only accelerating the overall airflow efficiency but also driving dynamic changes in the air duct shape. The high-speed airflow is no longer confined to a fixed path but periodically sweeps across different positions of the heat-generating element, completely solving the problem of insufficient heat dissipation in traditional fixed air ducts when components suddenly overheat. It solves the problem of local heat dissipation blind spots caused by the single airflow direction in traditional fixed air ducts, ensuring that all major heat-generating components 2 can be cooled evenly and efficiently. The cooperation between the infrared sensor 8 and the motor further enhances the airflow through the circular motion of the fan on the basis of mechanical adjustment, forming a dual guarantee from passive response to active enhancement. It can adapt to different scenarios from slight overheating to severe high load. By precisely controlling the airflow speed, direction and coverage, it can stabilize the temperature of the core heat-generating components within the safe threshold, avoiding accelerated component aging, material fatigue or sudden failure caused by long-term high temperature, and directly improving the operational stability and service life of the equipment.

[0028] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
