[0016] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0017] like Figure 1-Figure 6 As shown: An emergency lighting centralized power supply module comprises a fire emergency power supply box 1 and a box door 2 hinged to the surface of the fire emergency power supply box 1 through hinges.

[0018] In order to quickly and effectively reduce the temperature inside the fire emergency power supply box 1, it also includes a heat dissipation component 3 installed on both sides of the fire emergency power supply box 1. The heat dissipation component 3 includes dust filters 31 fixed on both sides of the surface of the fire emergency power supply box 1 and a heat dissipation frame 32 fixed on the side of the fire emergency power supply box 1 close to the dust filter 31 and a heat dissipation fan 33 screwed to the inside of the heat dissipation frame 32. The inside of the heat dissipation frame 32 is rotatably connected to a reciprocating screw 38 through a bearing frame. The surface of the reciprocating screw 38 is threadedly connected to a threaded block 39, and the surface of the threaded block 39 is fixed to a cleaning plate 310.

[0019] In this embodiment: by starting the heat dissipation fan 33, the external cold air is sucked in from the dust filter 31, and the dust filter 31 effectively intercepts dust impurities in the air, preventing these tiny particles from entering the power box, avoiding damage to electronic components, and preventing the normal operation of the electronic components inside the fire emergency power supply box 1. The sucked cold air flows inside the fire emergency power supply box 1 under the action of the heat dissipation fan 33, takes away the heat and then discharges it out of the box, thereby realizing the heat dissipation and cooling of the power module. By the rotation of the reciprocating screw 38, the threaded block 39 threadedly connected to the surface of the reciprocating screw 38 makes a linear reciprocating motion along the screw when the screw rotates. The threaded block 39 drives the cleaning plate 310 fixed on its surface to move, so that the dust accumulated on the dust filter 31 can be removed, ensuring smooth ventilation of the dust filter 31, continuously playing a good filtering role, ensuring the air permeability of the dust filter 31, so that the external cold air can smoothly pass through the dust filter 31 into the fire emergency power supply box 1, and exchange heat with the heating elements in the box, thereby realizing efficient heat dissipation and cooling of the power module.

[0020] It should be noted that the ventilation window opened on the back of the fire emergency power supply box 1 can discharge the cold air sucked in by the heat dissipation fan 33 after flowing inside the fire emergency power supply box 1 and completing heat exchange, thereby reducing the temperature inside the fire emergency power supply box 1 and ensuring that the electronic components of the emergency lighting centralized power supply module can operate stably under a suitable temperature environment. The ventilation window provides a smooth exhaust channel for the heated air, so that it is discharged out of the box through the ventilation window in an orderly manner, forming a complete and efficient air circulation and heat dissipation path, ensuring that the inside of the fire emergency power supply box 1 is always in a good heat dissipation state, greatly improving the operating stability and reliability of the emergency lighting centralized power supply module.

[0021] In an optional embodiment: the output end of the heat dissipation fan 33 is connected to a driving shaft 34, a transmission shaft 36 is provided on one side of the driving shaft 34, the transmission shaft 36 is rotatably connected to the inside of the heat dissipation frame 32 through a bearing frame, and a transmission belt 35 is connected between the transmission shaft 36 and the driving shaft 34 through pulleys, a bevel gear pair 37 is fixed to one end of the transmission shaft 36, and the bevel gear of the bevel gear pair 37 is coaxially fixedly connected to one end of the reciprocating screw rod 38, a cleaning brush 311 is fixed to one side of the cleaning plate 310 close to the dust filter net 31, and the cleaning brush 311 is in contact with the dust filter net 31, and positioning rods 312 are symmetrically fixed on both sides of the inside of the heat dissipation frame 32 close to the cleaning plate 310, and the cleaning plate 310 is slidably connected to the surface of the positioning rod 312 through the opened positioning groove.

[0022] In this embodiment: the heat dissipation fan 33 is connected to the transmission shaft 36 through the drive shaft 34 via the transmission belt 35 to achieve power transmission. The transmission shaft 36 rotates, driving the bevel gear pair 37 fixed at one end thereof to operate, thereby causing the reciprocating screw 38 coaxially fixed with the other bevel gear of the bevel gear pair 37 to rotate. The threaded block 39 threadedly connected to the surface of the reciprocating screw 38 makes a linear reciprocating motion along the screw when the screw rotates. The threaded block 39 drives the cleaning plate 310 fixed on its surface to move. The cleaning plate 310 slides on the surface of the positioning rod 312 through the positioning groove provided, ensuring that the cleaning plate 310 moves smoothly along the predetermined trajectory to avoid deviation or shaking. The cleaning brush 311 fixed on one side of the cleaning plate 310 is in contact with the dust filter 31. During the reciprocating motion of the cleaning plate 310, the cleaning brush 311 continuously cleans the dust on the surface of the dust filter 31, removes the dust accumulated on the dust filter 31, and ensures smooth ventilation of the dust filter 31. Furthermore, the power source for the cleaning brush 311 is provided by the heat dissipation fan 33, and no additional power mechanism is required. This not only saves costs but also ensures synchronization with heat dissipation requirements.

[0023] It should be noted that the cleaning brush 311 can remove accumulated dust in time, ensure that the dust filter 31 always maintains good air permeability, and ensure that the dust filter 31 will not reduce the filtering effect due to dust clogging during long-term use, thereby ensuring the continuous and stable operation of the heat dissipation system, extending the service life of the dust filter 31, and reducing the frequency and cost of replacing the dust filter 31.

[0024] Going further: In combination with the above content, in order to realize automatic opening and closing of the ventilating opening at the location of the dust filter 31, it also includes a closing component 4 installed on both sides of the surface of the fire emergency power supply box 1, and the closing component 4 includes a telescopic air cylinder 41 fixed on the upper and lower sides of the heat dissipation frame 32, and a piston 42 slidably connected to the inside of the telescopic air cylinder 41 and a push-pull rod 43 fixed to one end of the piston 42, and the push-pull rod 43 is slidably connected to the inside of the telescopic air cylinder 41, and a push-pull frame 45 is fixed to one end of the push-pull rod 43, and a closing plate 46 is fixed to one side of the push-pull frame 45, and the closing plate 46 is attached to the outer surface of the dust filter 31.

[0025] In this embodiment: when the emergency lighting centralized power supply module is working, heat is generated. When the internal temperature of the fire emergency power supply box 1 is normal, the temperature of the heated fin plate 44 is low, and the piston 42 in the telescopic gas cylinder 41 is in a relatively stable position. Once the internal temperature of the power supply box rises, the heat is transferred to the heated fin plate 44, and the temperature of the heated fin plate 44 rises, thereby causing the gas in the telescopic gas cylinder 41 to expand due to the heat. The gas expansion pushes the piston 42 to slide inside the telescopic gas cylinder 41, thereby causing the push-pull rod 43 fixed at one end of the piston 42 to move accordingly. As the push-pull rod 43 moves, the push-pull frame 45 can be driven to move, so that the push-pull frame 45 drives the closing plate 46 fixed on one side thereof to move along the surface of the fire emergency power supply box 1, so that the closing plate 46 can be moved along the outer surface of the dust filter net 31, and the vent where the dust filter net 31 is located is opened to ensure normal heat dissipation and ventilation functions, and can realize intelligent response to changes in the internal temperature of the fire emergency power supply box 1, realize automatic opening and closing of the vent at the location of the dust filter net 31, and adjust the heat dissipation intensity.

[0026] In an optional embodiment: a plurality of groups of equidistantly arranged heated fin plates 44 are fixed to the surface of the telescopic air cylinder 41, a clearance groove compatible with the push-pull frame 45 is provided on the surface of the fire emergency power supply box 1, a plurality of groups of equidistantly arranged positioning wheels 47 are symmetrically fixed on the upper and lower sides of the closing plate 46, a positioning seat 48 is fixed to the side of the surface of the fire emergency power supply box 1 close to the positioning wheel 47, and the positioning wheel 47 is slidably connected to the wheel groove provided in the positioning seat 48, two groups of connecting plates 49 are fixed to one side of the closing plate 46, a tension sensor 411 is fixed to the side of the surface of the fire emergency power supply box 1 close to the two groups of connecting plates 49, and a tension spring 410 is fixed between the connecting plate 49 and the tension sensor 411.

[0027] In this embodiment: as the closing plate 46 moves, it can drive the connecting plate 49 to move synchronously, thereby stretching the tension spring 410 to deform and generate elastic force, thereby pulling the tension sensor 411 to generate an electrical signal. When the electrical signal generated by the tension sensor 411 reaches the threshold, it means that the internal temperature of the fire emergency power supply box 1 is too high and needs to be dissipated immediately. When the internal temperature of the power box drops, the gas in the telescopic air cylinder 41 cools and contracts, and the piston 42 moves in the opposite direction under the tension of the tension spring 410. The closing plate 46 is reset by the push-pull rod 43 and the push-pull frame 45, so that the dust filter 31 can be closed to reduce the entry of external dust and moisture. Then the tension sensor 411 controls and turns off the cooling fan 33 to prevent harmful particles such as dust and moisture from entering the fire emergency power supply box 1 through the dust filter 31, thereby ensuring the stability of the internal environment of the fire emergency power supply box 1, protecting the internal electronic components, and improving the reliability and safety of the equipment operation.

[0028] It should be noted that: when the electrical signal generated by the tension sensor 411 reaches the preset threshold, it means that the internal temperature of the power box is too high and urgently needs to be cooled. At this time, the system will automatically start the cooling fan 33 to quickly draw in the outside cold air from the dust filter 31, greatly shortening the time interval from temperature abnormality to cooling startup, and being able to respond to high temperature conditions in the first time, effectively preventing equipment failures caused by excessive temperature, and ensuring that the emergency lighting centralized power supply module is always in a safe and stable working state.

[0029] The working principle and use process of the present invention are as follows: when the emergency lighting centralized power supply module is working, heat will be generated. When the temperature inside the fire emergency power supply box 1 is normal, the temperature of the heated fin plate 44 is relatively low, and the piston 42 in the telescopic gas cylinder 41 is in a relatively stable position. Once the temperature inside the power supply box rises, the heat is transferred to the heated fin plate 44, and the temperature of the heated fin plate 44 rises, thereby causing the gas in the telescopic gas cylinder 41 to expand due to the heat. The gas expansion pushes the piston 42 to slide inside the telescopic gas cylinder 41, thereby causing the push-pull rod 43 fixed at one end of the piston 42 to move accordingly. As the push-pull rod 43 moves, the push-pull frame 45 can be driven to move, so that the push-pull frame 45 drives the closing plate 46 fixed on one side thereof to move along the fire emergency power supply box 1 The surface moves, and the positioning wheels 47 on the upper and lower sides of the closing plate 46 slide in the wheel grooves opened inside the positioning seat 48 to ensure the stability and accuracy of the movement of the closing plate 46, so that the closing plate 46 can be moved along the outer surface of the dust filter 31, and the vent where the dust filter 31 is located is opened to ensure normal heat dissipation and ventilation functions, and can realize intelligent response to temperature changes inside the fire emergency power supply box 1, and automatically open and close the vent where the dust filter 31 is located, adjust the heat dissipation intensity, and ensure that the power module inside the fire emergency power supply box 1 is always operated within an appropriate temperature range, effectively avoiding performance degradation or failure caused by overheating, enhancing the reliability of the overall heat dissipation system, and providing reliable guarantee for the stable operation of the emergency lighting system.

[0030] Furthermore, as the closing plate 46 moves, the connecting plate 49 can be driven to move synchronously, thereby stretching the tension spring 410 to deform and generate elastic force, thereby pulling the tension sensor 411 to generate an electrical signal. When the electrical signal generated by the tension sensor 411 reaches the threshold, it indicates that the internal temperature of the fire emergency power supply box 1 is too high and needs to be cooled immediately. It can accurately sense the internal temperature changes at all times, and respond quickly when the temperature is too high, and start the heat dissipation measures in time to ensure that the power module is always in a suitable working temperature environment, effectively avoiding performance degradation, component damage and even fire hazards caused by overheating, greatly improving the reliability and stability of the emergency lighting system, and then it can start automatically The cooling fan 33 is driven to suck in the outside cold air from the dust filter 31. The dust filter 31 effectively intercepts dust impurities in the air to prevent these tiny particles from entering the power box, thereby avoiding damage to electronic components and preventing the normal operation of the electronic components inside the fire emergency power box 1. The sucked cold air flows inside the fire emergency power box 1 under the action of the cooling fan 33, takes away the heat and then discharges it out of the box, thereby achieving heat dissipation and cooling of the power module. The cooling fan 33 is connected to the transmission shaft 36 via the transmission belt 35 through the drive shaft 34 to achieve power transmission. The transmission shaft 36 rotates to drive the bevel gear pair 37 fixed at one end thereof to operate, thereby causing the bevel gear 37 connected to the other bevel gear pair 37 to rotate. The coaxially fixed reciprocating screw 38 rotates, and the threaded block 39 threadedly connected to the surface of the reciprocating screw 38 makes a linear reciprocating motion along the screw when the screw rotates. The threaded block 39 drives the cleaning plate 310 fixed on its surface to move. The cleaning plate 310 slides on the surface of the positioning rod 312 through the positioning groove, ensuring that the cleaning plate 310 moves smoothly along the predetermined trajectory to avoid deviation or shaking. The cleaning brush 311 fixed on one side of the cleaning plate 310 is in contact with the dust filter 31. During the reciprocating motion of the cleaning plate 310, the cleaning brush 311 continuously sweeps the dust on the surface of the dust filter 31, removes the dust accumulated on the dust filter 31, and ensures that the dust filter 31 is ventilated smoothly and continuously. It plays a good filtering role, ensures the air permeability of the dust filter 31, and allows the external cold air to smoothly pass through the dust filter 31 into the fire emergency power supply box 1, and exchange heat with the heating elements in the box, thereby realizing efficient heat dissipation and cooling of the power module, greatly improving the heat dissipation efficiency, ensuring that the heat generated by the power module inside the fire emergency power supply box 1 can be dissipated in time, quickly and effectively reducing the temperature inside the fire emergency power supply box 1, and ensuring that the electronic components inside the fire emergency power supply box 1 can always work within a suitable temperature range, which helps to maintain the stable performance of the electronic components and ensures the normal operation of the emergency lighting system, thereby improving the performance stability and reliability of the power module.

[0031] Furthermore, when the temperature inside the power box drops, the gas in the telescopic air cylinder 41 cools and contracts, and the piston 42 moves in the opposite direction under the tension of the tension spring 410, and the closing plate 46 is reset by the push-pull rod 43 and the push-pull frame 45, so that the dust filter 31 can be closed to reduce the entry of external dust and moisture. Subsequently, the tension sensor 411 controls and turns off the cooling fan 33 to prevent harmful particles such as dust and moisture from entering the fire emergency power supply box 1 through the dust filter 31, thereby ensuring the stability of the internal environment of the fire emergency power supply box 1, protecting the internal electronic components, and improving the reliability and safety of the equipment operation.

[0032] The above description only describes the specific implementation mode of the present invention. Various examples do not limit the essential content of the present invention. After reading the description, ordinary technicians in the relevant technical field can modify or deform the specific implementation modes described above without departing from the essence and scope of the invention.
