Description

Technical Field

[0001] The present invention relates to the technical field of UPS power supplies, and particularly relates to a multifunctional UPS power supply. Background Art

[0002] A UPS, i.e., an uninterruptible power supply, is a system device that connects a battery (mostly a lead-acid maintenance-free battery) to a host, and converts direct current into commercial power through module circuits such as a host inverter. It is mainly used to provide stable and uninterrupted power supply for a single computer, a computer network system or other power electronic devices such as solenoid valves and pressure transmitters.

[0003] For existing UPS power supplies, such as a Chinese utility model patent document with the publication number CN212969165U, which discloses an explosion-proof UPS power supply, including a housing, an explosion-proof inner liner fixedly connected to the inner side of the housing, and a power supply arranged inside the housing. An opening cover is slidably connected to the outer side of the top end of the housing. A temperature sensor and a controller are fixedly connected to the bottom end of the opening cover. A carbon dioxide gas cylinder, an inflation valve and a solenoid valve are fixedly connected to the inner side of the opening cover. In this utility model, through components such as the temperature sensor, the carbon dioxide gas cylinder, the solenoid valve and the inflation valve, the impact caused by the explosion of the power supply due to too high voltage can be reduced. The explosion-proof inner liner plays a protective role. The temperature sensor can detect the temperature inside the housing in real time. When the power supply inside the housing explodes, the temperature inside the housing will suddenly rise, the solenoid valve will open, and the carbon dioxide inside the carbon dioxide gas cylinder will enter the inside of the housing through the solenoid valve, playing a role in cooling and extinguishing the fire.

[0004] For existing UPS power supplies, such as a Chinese utility model patent document with the publication number CN212968538U, which discloses a dust-proof structure for a UPS power supply, including a housing, a UPS power supply, a driving component; a shock-absorbing component, the shock-absorbing component is installed at the bottom of the UPS power supply, and the UPS power supply is connected to the bottom of the housing through the shock-absorbing component; a heat dissipation component, the heat dissipation component is installed inside the housing; a cleaning component, the cleaning component is installed inside the housing. In this device, by setting the shock-absorbing component, the vibration of the UPS power supply during the handling of the device can be reduced, thereby protecting the UPS power supply from damage. When using the heat dissipation component to dissipate heat from the UPS power supply, the heat dissipation fan is driven to move up and down, greatly expanding the heat dissipation range and improving the heat dissipation effect. When it is necessary to clean the dust-proof net, the dust-proof net is cleaned with a brush to remove the dust accumulated in the holes of the dust-proof net, preventing the dust-proof net from being blocked. At the same time, the driving motor is controlled to rotate forward and backward to drive the sleeve to move up and down, thereby driving the brush to move up and down, greatly expanding the cleaning range.

[0005] Based on the above, in existing UPS power supplies, they can generally be divided into two categories. One category is completely enclosed and can achieve explosion protection, but it cannot conduct ventilation and heat dissipation. The heat dissipation effect is poor, and it is easy to cause damage due to overheating. The other category has ventilation openings for heat dissipation on both sides. These ventilation openings are always open and cannot be closed, resulting in the spread of fire outward in case of problems such as fire, and further improvement is needed. Summary of the Invention

[0028] The following will describe in detail the implementation manners of the technical solution of the present application in conjunction with the accompanying drawings. The following implementation manners are only used to more clearly illustrate the technical solution of the present application, so they are only examples and cannot be used to limit the protection scope of the present application.

[0029] Refer to Figures 1 - 10 , a multifunctional UPS power supply, including an explosion-proof housing 10, a power supply body 100 is arranged inside the explosion-proof housing 10, and openings 110 are arranged on the left and right sides of the explosion-proof housing 10; a ventilation and dust prevention module 20 is arranged in the left and right openings 110 of the explosion-proof housing 10, and the explosion-proof housing 10 is provided with a driving module 30 for driving the ventilation and dust prevention module 20 to move left and right; the ventilation and dust prevention module 20 includes a filter screen plate 210, a cleaning plate 220 and a sealing plate 230 arranged in sequence from inside to outside, and cleaning columns 221 are arranged on the cleaning plate 220 corresponding to the filter holes 213 of the filter screen plate 210; a plurality of connection holes 214 are arranged on the filter screen plate 210, and connection columns 240 inserted into the connection holes 214 are arranged on the sealing plate 230, and a limiting member 250 is connected to one end of the connection column 240 away from the sealing plate 230, and the limiting member 250 can be attached to the surface of the filter screen plate 210 facing away from the sealing plate 230, and a first elastic element 260 is arranged between the filter screen plate 210 and the sealing plate 230; the first elastic element 260 applies a force to the filter screen plate 210 and the sealing plate 230, so that a ventilation gap 60 is maintained between the filter screen plate 210 and the sealing plate 230; a limiting block 150 that can be attached to the surface of the filter screen plate 210 facing away from the sealing plate 230 is arranged on the inner wall of the explosion-proof housing 10.

[0030] In the present invention, the driving module 30 can drive the ventilation and dust-proof module 20 to move sequentially from the outside to the inside at the ventilation position, the closed position, the cleaning position, and the driving position.

[0031] Refer to Figure 6 , when the ventilation and dust-proof module 20 is at the ventilation position, the sealing plate 230 of the ventilation and dust-proof module 20 is located outside the explosion-proof housing 10. In this state, external air enters the inside of the explosion-proof housing 10 through the ventilation gap 60 and the filter holes 213 to provide heat dissipation for the power supply body 110. At this position, when the external air passes through the filter holes 213, particulate matter with a particle size larger than the aperture of the filter holes 213 in the air can be filtered, playing a filtering role.

[0032] Refer to Figure 2 , when the ventilation and dust-proof module 20 is at the closed position, the sealing plate 230 is located inside the explosion-proof housing 10, and the peripheral wall of the sealing plate 230 fits against the inner wall of the explosion-proof housing 10, so that the ventilation gap 60 cannot communicate with the outside, that is, the inside of the entire explosion-proof housing 10 is in a sealed state. When the ventilation and dust-proof module 20 is at the closed position, the filter screen plate 210 abuts against the limiting block 150, and the filter screen plate 210 cannot move further inward relative to the explosion-proof housing 10.

[0033] Refer to Figure 8 , when the ventilation and dust-proof module 20 is at the cleaning position, when the driving module 30 drives the sealing plate 230 to move from the closed position to the cleaning position, the sealing plate 230 and the cleaning plate 220 move inward together. During this movement process, the connecting column 240 moves relative to the connecting hole 214, so that the first elastic element 260 is compressed. At the same time, the cleaning column 221 is inserted into the filter hole 213 to push the dust particles inside the filter hole 213 to the outside, realizing cleaning. When the ventilation and dust-proof module 20 is at the cleaning position, there is still a driving distance A between the cleaning plate 220 and the filter screen plate 210.

[0034] Refer to Figure 8 and Figure 10 , when the ventilation and dust-proof module 20 is at the cleaning position, there is still a driving distance A between the cleaning plate 220 and the filter screen plate 210. As the driving module 30 continues to drive the sealing plate 230 to move from the cleaning position to the driving position, the connecting column 240 pushes the driving component 50 for power transmission.

[0035] Refer to Figure 2 , a fire extinguishing device 40 is arranged in the explosion-proof housing 10, and the explosion-proof housing 10 is provided with a driving component 50 for driving the fire extinguishing device 40 to be opened.

[0036] Refer to Figure 2 , when the ventilation and dust-proof module 20 moves relative to the explosion-proof housing 10, it can be in transmission cooperation with the driving component 50 to drive the fire extinguishing device 40 to be opened.

[0037] See Figure 3 and Figure 4 As shown in FIGS. and, the fire extinguishing device 40 includes a powder supply pipe 400. The powder supply pipe 400 is connected with a plurality of inner pipes 410. A plurality of first powder spraying holes 420 are arranged in sequence along the front-rear direction on the lower surface of the inner pipe 410. The plurality of inner pipes 410 are arranged in sequence along the left-right direction. An outer pipe 430 is sleeved on the outer surface of the inner pipe 410. The outer pipe 430 is rotatably arranged relative to the inner pipe 410. A plurality of second powder spraying holes 440 are arranged in sequence along the front-rear direction on the outer pipe 430. The outer pipe 430 can be rotated from a first position to a second position relative to the inner pipe 410. When the outer pipe 430 is in the second position, the first powder spraying holes 420 communicate with the second powder spraying holes 440. The powder supply pipe 400 is connected with a powder supply tank. The powder supply tank is a pressure tank body. When the first powder spraying holes 420 communicate with the second powder spraying holes 440, the fire extinguishing powder in the pressure tank body is sprayed into the explosion-proof housing 100 to play a role in extinguishing fire.

[0038] See Figure 3 As shown in FIGS. and, the driving assembly 50 includes a first rack 510 that moves left and right relative to the explosion-proof housing 10. The outer pipe 430 is provided with a first gear 450 that meshes with the first rack 510. Second elastic elements 530 are arranged at the left and right ends of the first rack 510. The second elastic elements 530 are connected with the explosion-proof housing 10. A driven mating member 550 is connected to any one of the left and right ends of the first rack 510. When the ventilation and dust-proof module 20 moves from the outside to the inside, it can push the driven mating member 550 together with the first rack 510 to move, so as to drive the first gear 450 to drive the outer pipe 430 to rotate.

[0039] When the second elastic element 530 functions, it restrains the first rack 510 to stay in the closed position. When the driving module 30 drives the sealing plate 230 to move from the cleaning position to the driving position, the connecting column 240 pushes the first rack 510 to move, so that the first rack 510 moves from the closed position to the open position. During this movement process, the first rack 510 drives the first gear 450 to rotate, so that the outer pipe 430 rotates relative to the inner pipe 410, and the originally misaligned first powder spraying holes 420 communicate with the second powder spraying holes 440.

[0040] When the sealing plate 230 moves from the driving position to the cleaning position, the first rack 510 has no external force restraint. Under the action of the second elastic element 530, it drives the first rack 510 to move from the open position to the closed position to realize position reset.

[0041] See Figure 3 and Figure 4, a slide rail groove 130 is provided on the inner wall of the explosion-proof housing 10, and the first rack 510 is arranged to move left and right in the slide rail groove 130; first positioning columns 520 are provided at the left and right ends of the first rack 510, and second positioning columns 540 are provided at the left and right ends of the slide rail groove 130. The second elastic element 530 is a spring, and the second elastic element 530 is sleeved on the first positioning column 520 and the second positioning column 540.

[0042] In some embodiments, the first elastic element 260 is a spring, and the first elastic element 260 is sleeved on the connecting column 240; one end of the first elastic element 260 abuts against the filter screen plate 210, and the other end abuts against the sealing plate 230.

[0043] In some embodiments, the driving module 30 includes a linear driving element 310 provided in the explosion-proof housing 10. The telescopic end of the linear driving element 310 is connected with a connecting piece 320, and the connecting piece 320 is fixedly connected with the sealing plate 230.

[0044] In some embodiments, the linear driving element 310 adopts an electric cylinder.

[0045] In some embodiments, a blower is provided in the explosion-proof housing 10; when the ventilation and dust prevention module 20 is in the ventilation position, the blower can drive external air into the interior of the explosion-proof housing 10 to improve the heat exchange efficiency.

[0046] In some embodiments, a temperature sensor is provided in the explosion-proof housing 10; the temperature sensor and the driving module 30 are connected to the control terminal. The temperature sensor detects the temperature value inside the explosion-proof housing 10 and communicates with the control terminal in real time. When the temperature sensor detects that the temperature value is higher than the first preset value, the control driving module 30 drives the ventilation and dust prevention module 20 to move from the ventilation position to the closed position to prevent the fire from spreading outward due to battery explosion. When the temperature sensor detects that the temperature value is higher than the second preset value, the control driving module 30 drives the ventilation and dust prevention module 20 to move from the closed position to the driving position to spray fire extinguishing powder for fire extinguishing.

[0047] In some embodiments, a camera is provided in the explosion-proof housing 10. The camera can be remotely monitored to control the driving module 30 to drive the ventilation and dust prevention module 20 to move from the closed position to the driving position to spray fire extinguishing powder for fire extinguishing according to whether a fire breaks out.

[0048] In some embodiments, the filter screen plate 210 is composed of a frame 211 and a mesh plate 212 arranged in the frame 211. The mesh plate 212 is assembled with the frame 211 in a detachable connection manner.
