Description

Technical Field

[0001] The invention relates to the technical field of communication power supply equipment, and in particular to a power supply cabinet of a UPS uninterruptible power supply. Background Art

[0002] UPS is a system device that connects the battery to the host and converts DC power into AC power through the host inverter and other module circuits. It is mainly used to provide stable and uninterrupted power supply to a single computer, communication room, computer network system or other power electronic equipment such as solenoid valves, pressure transmitters, etc. When the AC power input is normal, UPS stabilizes the AC power and supplies it to the load. At this time, UPS is an AC voltage stabilizer. At the same time, it also charges the battery inside the machine. When the AC power is interrupted, UPS immediately switches the DC power of the battery to 220V AC power to the load through the inverter switching conversion method, so that the load maintains normal operation and protects the load software and hardware from damage. UPS equipment can usually provide protection against overvoltage or undervoltage.

[0003] Since the UPS uninterruptible power supply needs to work uninterruptedly for a long time, the power cabinet used to install the UPS uninterruptible power supply needs to meet strict operating conditions and design requirements to ensure that the UPS uninterruptible power supply can provide stable and uninterrupted power supply.

[0004] However, after the existing power cabinet has been running for a long time, dust will accumulate. The dust will enter the interior of the power cabinet and adhere to the electrical components, thereby affecting the working efficiency of the UPS uninterruptible power supply and even causing the UPS uninterruptible power supply to stop working due to overheating.

[0005] For example, the Chinese invention patent with publication number CN114927969A discloses a high-security multi-module UPS uninterruptible power supply, including a shell, a symmetrical array of placement slots on both sides of the inner wall of the shell, a rack movably mounted inside the placement slot, and a pressing device is attached to the top of the inner wall of the shell and the bottom of the rack, and the pressing device includes a telescopic airbag, a limiting ring, a fixed baffle and a movable baffle. The invention cooperates with the structures such as the pressing device, the rack and the shell, and sets a limiting ring on the surface of the telescopic airbag, so that the telescopic airbag will expand downward first, so as to press against the top of the component, and then the front end of the component is covered with a movable baffle, and then the fastening screw is screwed to fix and limit, thereby improving the stability of the component, and because the telescopic airbag plays a role of shock absorption and buffering, the safety of the component is improved. In the above patent, when the UPS uninterruptible power supply is dissipating heat, dust and other particulate matter in the air is blocked and filtered through a dustproof net. However, the dustproof net is clogged with dust after long-term use, which not only makes it difficult for air to circulate through the dustproof net, but also the heat inside the UPS uninterruptible power supply cannot be effectively dissipated, causing the internal temperature of the power supply to rise and shortening the service life of its internal electrical components. There is also a problem that when the dustproof net is replaced, if the UPS uninterruptible power supply does not stop working, dust will enter the inside and adhere to the electrical components. If it stops working, the working efficiency of the UPS uninterruptible power supply is affected.

[0006] In view of this, the inventor has designed a UPS uninterruptible power supply cabinet based on many years of production design experience in this field and related fields after repeated experiments, in order to solve the problems existing in the prior art. Summary of the invention

[0007] The object of the present invention is to provide a power supply cabinet of a UPS uninterruptible power supply, which can effectively prevent the adhesion and accumulation of dust and improve the working efficiency of the UPS uninterruptible power supply.

[0008] In order to achieve the above-mentioned purpose, the present invention proposes a power cabinet for a UPS uninterruptible power supply, wherein the power cabinet includes an outer shell, a vent is provided on the outer shell, and a dustproof device is installed on the outer shell to match the vent, and the dustproof device includes a dustproof shell, a dustproof net, a driving mechanism and two rotating shaft assemblies. The dustproof shell is installed on the outer wall of the outer shell and matches the vent, and the two rotating shaft assemblies are respectively located at opposite ends of the dustproof shell and can be rotatably installed on the dustproof shell. The dustproof net is tensioned on the two rotating shaft assemblies, and the driving mechanism is connected to at least one of the rotating shaft assemblies and drives the dustproof net to rotate cyclically through the rotating shaft assembly.

[0009] Compared with the prior art, the present invention has the following characteristics and advantages:

[0010] The power cabinet of the UPS uninterruptible power supply proposed by the present invention has a dustproof device with a dustproof net stretched on two rotating shaft assemblies, and the dustproof net rotates cyclically under the drive of at least one rotating shaft assembly. With the above structure, the dustproof net forms a dual dustproof function, effectively preventing dust from entering the vent with the air flow; at the same time, since the dustproof net is in continuous circulation, it is effectively avoided that a certain area of ​​the dustproof net is in dustproof work for a long time, thereby causing a large amount of dust to accumulate; in addition, since the dustproof net is in continuous circulation, it also reduces the dust adhering to the dustproof net, ensuring the air circulation efficiency of the dustproof net and the vent, thereby ensuring that the internal temperature of the power cabinet is within the normal operating temperature range of the UPS uninterruptible power supply.

[0026] The power cabinet of the UPS uninterruptible power supply proposed in the present invention has a dustproof device 3 with a dustproof net 310 tensioned on two rotating shaft assemblies. The dustproof net 310 forms a dual dustproof function, effectively preventing dust from entering the vent 13 with the airflow; at the same time, since the dustproof net 310 is in a continuous circulation, it is effectively avoided that a certain area of ​​the dustproof net 310 is subjected to dustproof work for a long time, thereby causing a large amount of dust accumulation; in addition, since the dustproof net 310 is in a continuous circulation, the dust adhesion on the dustproof net 310 is also reduced, thereby ensuring the air circulation efficiency of the dustproof net 310 and the vent 13, thereby ensuring that the internal temperature of the power cabinet is within the normal operating temperature range of the UPS uninterruptible power supply.

[0027] The power cabinet of the UPS uninterruptible power supply proposed by the present invention has a dustproof net 310 of the dustproof device 3 that can circulate and rotate, thereby reducing dust accumulation and effectively extending the service life of the dustproof net 310 and the dustproof device 3.

[0028] In an optional embodiment of the present invention, a synchronization mechanism is connected between the two rotating shaft assemblies, and the synchronization mechanism drives the two rotating shaft assemblies to rotate synchronously to synchronously drive the dustproof net 310, effectively ensuring that the dustproof net 310 can stably cyclically rotate.

[0029] In an optional example of this embodiment, the synchronization mechanism includes a synchronization belt 309 and two gear parts 308. The two gear parts 308 are respectively fixed on the two rotating shaft assemblies. The synchronization belt 309 is respectively meshed with the arc surfaces of the two gear parts 308. The synchronous rotation of the two rotating shaft assemblies is achieved through the meshing of the synchronization belt 309 and the two gear parts 308.

[0030] In an optional example of the present invention, two rotating shaft assemblies are respectively located at the top and bottom ends of the dustproof shell 301, the rotating shaft assembly located at the top includes a first rotating rod 303 and two rotating cylinders 305 mounted outside the first rotating rod 303, the rotating shaft assembly located at the bottom includes a second rotating rod 304 and two rotating cylinders 305 mounted outside the second rotating rod 304, the first rotating rod 303 and the second rotating rod 304 are arranged in parallel, the dustproof net 310 is tensioned outside the four rotating cylinders 305, and the dustproof net 310 is driven to rotate in a circle through the friction between each rotating cylinder 305 and the dustproof net 310.

[0031] Furthermore, the two gear members 308 of the synchronization mechanism are respectively mounted on the end of the first rotating rod 303 and the end of the second rotating rod 304 on the same side.

[0032] In an optional embodiment of the present invention, the driving mechanism 302 is a motor.

[0033] In this embodiment, the motor can be directly connected to the first rotating rod 303 or the second rotating rod 304; the motor can also be first connected to the synchronization mechanism, and then the synchronization mechanism is used to synchronously drive the first rotating rod 303 and the second rotating rod 304 to rotate.

[0034] In an optional embodiment of the present invention, a support frame 313 is provided between the two rotating shaft assemblies, at least one second ladder block 314 is provided on the support frame 313, at least one first ladder block 311 is provided on the inner wall of the dustproof net 310, the second ladder block 314 is aligned with the first ladder block 311, and the first ladder block 311 can collide with the second ladder block 314 when the dustproof net 310 rotates. With the above structure, the first ladder block 311 collides with the second ladder block 314 when passing through it, thereby causing the dustproof net 310 to vibrate, so as to shake off the dust attached to the dustproof net 310; when the dustproof net 310 circulates, the first ladder block 311 circulates through the second ladder block 314 and collides with the second ladder block 314, thereby realizing the regular vibration of the dustproof net 310, and continuously reducing the dust accumulation on the dustproof net 310.

When the dustproof net 310 rotates cyclically, the plurality of first ladder blocks 311 sequentially pass through the plurality of second ladder blocks 314, thereby causing the dustproof net 310 to vibrate continuously, and dust attached to the dustproof net 310 can be continuously shaken off, thereby reducing the clogging of the dustproof net 310 by dust and solving the problem of increased internal temperature of the power cabinet.

[0036] In an optional example of this embodiment, a plurality of balls 315 are rotatably provided on the surface of the second ladder block 314, and an arc groove 312 adapted to the balls 315 is provided on the surface of the first ladder block 311. With the above structure, when the first ladder block 311 contacts the second ladder block 314, the balls 315 enter the arc groove 312 and slide, which can effectively reduce the friction between the first ladder block 311 and the second ladder block 314.

[0037] In an optional embodiment of the present invention, a cleaning brush for cleaning the dustproof net 310 is also installed on the dustproof shell 301. The cleaning brush can perform secondary cleaning on the dustproof net 310, further reducing dust accumulation on the dustproof net 310.

[0038] In an optional example of this embodiment, the cleaning brush includes a mounting plate 318, a cleaning brush body 319 and two elastic drive components, the two elastic drive components are respectively mounted on two opposite side walls of the dustproof shell 301, the mounting plate 318 is arranged parallel to the dustproof net 310, the two ends of the mounting plate 318 are respectively connected to the two elastic drive components, the two elastic drive components drive the mounting plate 318 to move back and forth, and the cleaning brush body 319 is fixedly connected to the plate surface of the mounting plate 318 facing the dustproof net 310 and contacts the dustproof net 310. With the above structure, the mounting plate 318 is driven by the two elastic drive components and then moves back and forth between the two drive components, and the cleaning brush body 319 on the mounting plate 318 reciprocates to clean the dustproof net 310, thereby achieving a dust removal effect.

With the above structure, the second toggle member 307 will collide with the second special-shaped member 321 on the slide 317 during the process of following the second rotating rod 304 to rotate. At this time, the second toggle member 307 squeezes the second special-shaped member 321, so that the second special-shaped member 321 drives the slide 317 and the arc-shaped mounting plate 318 and the cleaning brush body 319 to move. At this time, the first spring 320 close to the second special-shaped member 321 is squeezed and contracts, while the first spring 320 at the other side of the slide 317 is extended. When the second toggle member 307 gradually moves away from the second special-shaped member 321 during the rotation, the first springs 320 on both sides of the dustproof shell 301 drive the slide 317 to reset under the action of their own elasticity. As the second rotating rod 304 continues to rotate, the slide 317 drives the mounting plate 318 and the cleaning brush body 319 to reciprocate. At this time, the cleaning brush body 319 performs secondary cleaning on the dustproof net 310.

[0041] In an optional example of the present invention, the cleaning brush body 319 is glued to the mounting plate 318 .

[0044] With the above structure, the cleaning liquid (alcohol) is poured into the capsule bottle 402, and then the bottle cap 404 is tightened to seal the capsule bottle 402. At this time, the capsule bottle 402 is placed in the fixing frame 401, and the capsule bottle 402 is connected to the fixing frame 401 through the thread by rotating the fixing member 403, so that the capsule bottle 402 can be replaced regularly. When the first rotating rod 303 rotates, the first toggle member 306 can be driven to rotate. At this time, the first toggle member 306 gradually moves with the first special-shaped member 410 contacts and squeezes the first special-shaped piece 410 to move. At this time, the first special-shaped piece 410 squeezes the capsule bottle 402 through the circular plate 409 to shrink. When the capsule bottle 402 is squeezed and shrinks, the pressure generated can push the internal cleaning liquid into the drain pipe 405 and be evenly sprayed on the dustproof net 310 through the atomizing nozzle 406. At this time, the alcohol on the dustproof net 310 can dissolve and soften dust and other particles, so that the dust can be shaken off better, reducing the problem of stubborn dust being difficult to clean.

[0045] In an optional example, the arc surface of the slide bar 407 is sleeved with a second spring 408, and the two ends of the second spring 408 are respectively fixedly connected to the slide bar 407 and the fixed frame 401. With the above structure, when the circular plate 409 moves under the action of the first special-shaped member 410, it can drive the slide bar 407 to move, and at this time, the second spring 408 is extended under the action of the slide bar 407. When the first toggle member 306 is away from the first special-shaped member 410, the second spring 408 can drive the slide frame 317 to reset. With the cooperation of the first toggle member 306 and the first special-shaped member 410, the capsule bottle 402 can be continuously squeezed to perform the spraying work.

The first rotating rod 303 and the second rotating rod 304 drive the dustproof net 310 to rotate in a circle through the rotating drum 305, which not only allows the dustproof net 310 to form a double layer for double dustproof work, but also avoids a certain area of ​​the dustproof net 310 from performing dustproof work for a long time, thereby preventing a large amount of dust from accumulating, thereby improving the dust blocking effect and service life of the dustproof net 310. Driven by the dustproof net 310, the first ladder block 311 gradually contacts the second ladder block 314 on the support frame 313. At this time, the first ladder block 311 is squeezed by the second ladder block 314, driving the dustproof net 310 to deform and expand outward. As the first ladder block 311 gradually moves away from the second ladder block 314, the dustproof net 310 recovers and vibrates under the action of its own elasticity. The cooperation between the first ladder block 311 and the second ladder block 314 makes the dustproof net 310 vibrate continuously, which can shake off the dust attached to the dustproof net 310, reducing the problem of the dustproof net 310 being blocked by dust, resulting in the internal temperature increase of the UPS uninterruptible power supply. When the first ladder block 311 contacts the second ladder block 314, the ball 315 enters the arc groove 312 and slides, which can effectively reduce the friction between the first ladder block 311 and the second ladder block 314.

[0061] Reference Figure 2-Figure 8As shown, slides 317 are slidably connected to both sides of the dustproof shell 301, and a first spring 320 is fixedly connected to a side where the slides 317 and the dustproof shell 301 are close to each other, and a mounting plate 318 is fixedly connected to a side where the two slides 317 are close to each other, and a cleaning brush body 319 is glued to the surface of the mounting plate 318, and a cavity 316 is defined on the inner wall of the dustproof shell 301, and the mounting plate 318 is located in the cavity 316, and the size of the mounting plate 318 is smaller than the size of the cavity 316, and the other end of the second rotating rod 304 is fixedly connected to a second toggle member 307, and a second special-shaped member 321 used in conjunction with the second toggle member 307 is fixedly connected to the surface of the slide 317.

[0062] In this embodiment, the second toggle member 307 will collide with the second special-shaped member 321 on the slide 317 while following the rotation of the second rotating rod 304. At this time, the second toggle member 307 squeezes the second special-shaped member 321, so that the second special-shaped member 321 drives the slide 317, the mounting plate 318 and the cleaning brush body 319 to move. At this time, the first spring 320 close to the second special-shaped member 321 is squeezed and contracts, while the first spring 320 at the other side of the slide 317 is extended. When the second toggle member 307 gradually moves away from the second special-shaped member 321 during the rotation, the first springs 320 on both sides of the dustproof shell 301 drive the slide 317 to reset under the action of their own elasticity. As the second rotating rod 304 continues to rotate, the slide 317 drives the mounting plate 318 and the cleaning brush body 319 to reciprocate. At this time, the cleaning brush body 319 performs secondary cleaning on the dustproof net 310.

[0063] Reference Figure 4 , Figure 5 and Figure 7 , Fig. 9 As shown, the spraying device 4 also includes a fixing part 403 threadedly connected to the inner wall of the fixing frame 401, the inner wall of the fixing part 403 is fixedly connected with a capsule bottle 402, the capsule bottle 402 is a telescopic rubber sleeve bottle, the arc surface of the capsule bottle 402 is threadedly connected with a bottle cap 404, the surface of the bottle cap 404 is fixedly connected with a drain pipe 405, the atomizing nozzle 406 is fixedly connected with the drain pipe 405, the surface of the fixing frame 401 is slidably connected with two sliding rods 407, the sides of the two sliding rods 407 close to each other are fixedly connected with a circular plate 409, the other end of the first rotating rod 303 is fixedly connected with a first toggle member 306, and the surface of the circular plate 409 is fixedly connected with a first special-shaped member 410 used in conjunction with the first toggle member 306.

[0064] In this embodiment, the cleaning liquid (alcohol) is poured into the capsule bottle 402, and then the bottle cap 404 is tightened to seal the capsule bottle 402. At this time, the capsule bottle 402 is placed in the fixing frame 401, and the capsule bottle 402 is connected to the fixing frame 401 through the thread by rotating the fixing member 403, so as to facilitate the regular replacement of the capsule bottle 402. When the first rotating rod 303 rotates, the first toggle member 306 can be driven to rotate. At this time, the first toggle member 306 gradually contacts the first special-shaped member 410 and squeezes the first special-shaped member 410 to move. The first special-shaped member 410 squeezes the capsule bottle 402 through the circular plate 409 to shrink. When the capsule bottle 402 is squeezed and shrinks, the generated pressure can push the internal cleaning liquid into the drain pipe 405 and be evenly sprayed on the dustproof net 310 through the atomizing nozzle 406. At this time, the alcohol on the dustproof net 310 can dissolve and soften dust and other particles, so that the dust can be shaken off better, reducing the problem of stubborn dust being difficult to clean.

[0065] Reference Fig. 9 As shown, the arc surface of the slide bar 407 is sleeved with a second spring 408 , and two ends of the second spring 408 are fixedly connected to the slide bar 407 and the fixing frame 401 respectively.

[0066] In this embodiment, when the circular plate 409 moves under the action of the first special-shaped member 410, it can drive the slide bar 407 to move. At this time, the second spring 408 is extended under the action of the slide bar 407. When the first toggle member 306 is away from the first special-shaped member 410, the second spring 408 can drive the slide 317 to reset. With the cooperation of the first toggle member 306 and the first special-shaped member 410, the capsule bottle 402 can be continuously squeezed to perform spraying.

[0067] Reference Figure 4 , Figure 5 and Figure 8 , Fig.10 As shown, the collecting device 5 also includes four supporting plates 53 fixedly connected to the surface of the supporting frame 51 , the surface of the supporting plate 53 is threadedly connected with a screw 54 , one end of the screw 54 is rotatably connected with a pressure plate 55 , and the collecting bag 52 is sleeved on the inner wall of the supporting frame 51 .

[0068] In this embodiment, the collecting bag 52 is placed in the supporting frame 51, and the screw 54 is rotated to drive the pressing plate 55 to move up and down. When the pressing plate 55 descends, the collecting bag 52 can be fixed. At this time, the collecting bag 52 can collect the fallen dust. When the collecting bag 52 is full, the screw 54 is rotated to drive the pressing plate 55 away from the collecting bag 52, and the collecting bag 52 can be replaced.

[0069] Reference Fig.10As shown, a dust removal plate 56 is fixedly connected to the surface of the dustproof shell 301, and a connecting piece 57 is fixedly connected to the surface of another slide 317. The connecting piece 57 is L-shaped, and a ball 58 is fixedly connected to the surface thereof.

[0070] In this embodiment, when the dust on the dustproof net 310 is shaken off, the dust discharge plate 56 can facilitate the falling dust to slide into the collection bag 52, and the slide 317 can drive the connecting member 57 to move when reciprocating under the action of the first toggle member 306 and the first special-shaped member 410. At this time, the connecting member 57 drives the ball 58 to hit the dust discharge plate 56, so as to shake off the dust attached to the dust discharge plate 56.

[0071] Working principle: When the UPS is working, the UPS is first controlled through the control panel 12, and the support legs 15 can support the shell 1 to prevent the shell 1 from directly contacting the ground. At this time, the driving member 21 is started, and the driving member 21 drives the fan blades 22 to rotate, and the outside air is sucked into the shell 1 through the vent 13, and the blown air can dissipate the heat generated by the electrical components when they are working.

[0072] At this time, the driving mechanism 302 is started, and the driving mechanism 302 drives the first rotating rod 303 and the gear part 308 to rotate. The gear part 308 on the first rotating rod 303 cooperates with the synchronous belt 309 to drive the four gear parts 308 to rotate synchronously. The first rotating rod 303 and the second rotating rod 304 drive the dustproof net 310 to rotate circularly through the rotating drum 305, which not only makes the dustproof net 310 form a double layer to perform double dust prevention work, but also avoids the situation where a certain area of ​​the dustproof net 310 performs dust prevention work for a long time, thereby preventing a large amount of dust from accumulating, thereby improving the dust blocking effect and service life of the dustproof net 310. The first ladder block 311 is gradually contacted with the second ladder block 314 on the support frame 313 under the drive of the dustproof net 310. The ladder block 311 is squeezed by the second ladder block 314, driving the dust net 310 to deform and expand outward. As the first ladder block 311 gradually moves away from the second ladder block 314, the dust net 310 recovers and vibrates under the action of its own elasticity. At this time, the first ladder block 311 and the second ladder block 314 cooperate to make the dust net 310 vibrate continuously, which can shake off the dust attached to the dust net 310, reducing the problem of the dust net 310 being blocked by dust, causing the internal temperature of the UPS uninterruptible power supply to rise. When the first ladder block 311 contacts the second ladder block 314, the ball 315 enters the arc groove 312 and slides, which can effectively reduce the friction between the first ladder block 311 and the second ladder block 314.

[0073] At the same time, the second toggle member 307 collides with the second shaped member 321 on the slide 317 during the process of following the second rotating rod 304 to rotate. At this time, the second toggle member 307 squeezes the second shaped member 321, so that the second shaped member 321 drives the slide 317, the mounting plate 318 and the cleaning brush body 319 to move, and the first spring 320 close to the second shaped member 321 is squeezed and contracts, while the first spring 320 on the other side of the slide 317 is stretched. When the second toggle member 307 gradually moves away from the second shaped member 321 during the rotation process, the first springs 320 on both sides of the dust cover 301 drive the slide 317 to reset under the action of their own elasticity. As the second rotating rod 304 continues to rotate, the slide 317 drives the mounting plate 318 and the cleaning brush body 319 to reciprocate, and at this time, the cleaning brush body 319 performs secondary cleaning on the dust net 310. In the dustproof device 3, through the coordinated use of the first ladder block 311 and the second ladder block 314 and the second toggle member 307 and the second special-shaped member 321, the dustproof net 310 can be double cleaned when it is working, thereby reducing the problem of dust adhering to the dustproof net 310, which causes the internal temperature of the UPS uninterruptible power supply to continue to rise and cause damage to electrical components. It is convenient for the dustproof net 310 to form a double dustproof function during the circulating motion, thereby further improving the working efficiency of the UPS uninterruptible power supply.

[0074] Furthermore, the staff can select a suitable pressure valve to be installed on the discharge pipe 405 and set a predetermined value. At this time, the cleaning liquid (alcohol) is poured into the capsule bottle 402, and then the bottle cap 404 is tightened to seal the capsule bottle 402, and the capsule bottle 402 is placed in the fixing frame 401, and the capsule bottle 402 is connected to the fixing frame 401 through a thread by rotating the fixing member 403, so as to facilitate the regular replacement of the capsule bottle 402. When the first rotating rod 303 rotates, the first toggle member 306 can be driven to rotate. At this time, the first toggle member 306 gradually contacts the first special-shaped member 410 and squeezes the first special-shaped member 410 to move. The first special-shaped member 410 squeezes the capsule bottle 402 through the circular plate 409 to shrink, and drives the slide bar 407 to move. At this time, the second spring 408 is extended under the action of the slide bar 407. When the first toggle member 306 is away from the first shaped member 410, the second spring 408 can drive the slide 317 to reset. With the cooperation of the first toggle member 306 and the first shaped member 410, the capsule bottle 402 can be continuously squeezed. When the capsule bottle 402 is squeezed and shrinks, the pressure generated can push the internal cleaning liquid into the drain pipe 405 and be evenly sprayed on the dustproof net 310 through the atomizing nozzle 406. The alcohol on the dustproof net 310 can dissolve and soften dust and other particles, so that the dust can be shaken off better, reducing the problem of stubborn dust being difficult to clean, and the airflow generated by the fan blade 22 during rotation can accelerate the volatilization of alcohol, which can not only absorb the heat near the UPS uninterruptible power supply, but also reduce the area on the dustproof net 310 sprayed with alcohol from entering the housing 1 after rotation. At the same time, it is only necessary to control the rotation direction of the dust net 310 so that it rotates toward the cleaning brush body 319 first, so that the alcohol can be effectively removed by the reciprocating cleaning brush body 319, further reducing the situation where alcohol enters the housing 1. By setting the spraying device 4, through the coordinated use of the first toggle member 306 and the first special-shaped member 410 as well as the fan blades 22 and the cleaning brush body 319, the capsule bottle 402 continuously sprays alcohol to soften and dissolve the stubborn dust on the dust net 310, facilitating the absorption of heat near the housing 1 when the alcohol evaporates, reducing the situation where alcohol enters the housing 1, and further improving the use effect of the UPS uninterruptible power supply.

[0075] The collection bag 52 is placed in the support frame 51, and the screw 54 is rotated at this time to drive the pressing plate 55 to move up and down. When the pressing plate 55 descends, the collection bag 52 can be fixed. When the dust on the dustproof net 310 is shaken off, the dust discharge plate 56 can facilitate the falling dust to slide into the collection bag 52, and the slide 317 can drive the connecting member 57 to move when it reciprocates under the action of the first toggle member 306 and the first special-shaped member. At this time, the connecting member 57 drives the ball 58 to hit the dust discharge plate 56, and the dust attached to the dust discharge plate 56 can be shaken off. When the collection bag 52 is full, the pressing plate 55 is driven away from the collection bag 52 by rotating the screw 54, and the collection bag 52 can be replaced at this time. By setting the collection device 5, through the coordinated use of the collection bag 52, the dust discharge plate 56 and the connecting member 57, it is convenient to collect the fallen dust, reduce the dust falling on the ground, and reduce the situation where the staff needs to clean it twice, and further improve the practicality of the UPS uninterruptible power supply.

[0076] The dustproof device 3 provided in the present invention can perform double cleaning on the dustproof net 310 when it is working, through the coordinated use of the first ladder block 311 and the second ladder block 314 and the second toggle member 307 and the second special-shaped member 321, thereby reducing the problem of dust adhering to the dustproof net 310, which causes the internal temperature of the UPS uninterruptible power supply to continue to rise and cause damage to electrical components; it is convenient for the dustproof net 310 to form a double dustproof function during the circulating motion, thereby further improving the working efficiency of the UPS uninterruptible power supply.

[0077] The spraying device 4 provided in the present invention, through the coordinated use of the first toggle member 306 and the first special-shaped member 410 as well as the fan blades 22 and the cleaning brush, enables the capsule bottle 402 to continuously spray alcohol, soften and dissolve the stubborn dust on the dustproof net 310, and facilitate the absorption of heat near the outer shell 1 when the alcohol evaporates, thereby reducing the situation where alcohol enters the outer shell 1, and further improving the use effect of the UPS uninterruptible power supply.

[0078] The collecting device 5 provided in the present invention, through the coordinated use of the collecting bag 52, the dust discharge plate 56 and the connecting piece 57, facilitates the collection of fallen dust, reduces the situation where dust falls on the ground and the need for secondary cleaning by the staff, and further improves the practicality of the UPS uninterruptible power supply.
