Description

Technical Field

[0001] The present invention belongs to the technical field of UPS, and in particular relates to a UPS compatible with a lithium battery management system. Background Art

[0002] A UPS (Uninterruptible Power Supply) compatible with a lithium battery management system is an electrical device that is mainly composed of a casing, a rain shelter on the casing, and a lithium battery management system and lithium batteries inside the casing. It is used to protect electrical equipment from sudden power outages or power failures. When the mains input is normal, the UPS stabilizes the mains and supplies it to the load, while charging the battery inside the machine. When the mains power is interrupted, the UPS immediately converts the battery's DC power through the lithium battery management system to convert the power through the inverter, and continues to supply AC power to the load to maintain the normal operation of the load and protect the load's software and hardware from damage. UPS is widely used. It can be used both indoors and outdoors, such as the ETC system at highway intersections to avoid power outages in the ETC system. However, in northern areas such as Northeast China and Inner Mongolia, the winter is long, snowfall is frequent, and the snowfall is large and lasts for a long time. For some larger outdoor UPS, snow is easily accumulated on the upper part during the snowfall season. The accumulated snow puts great pressure on the UPS awning, and then causes mechanical pressure on the outer shell. This can cause deformation of the outer shell and water leakage inside for a long time, leading to short circuit and burning of internal components. The maintenance plan of the existing technology is that sanitation workers go there to manually shovel snow at regular intervals. The operation process is not only intensive, but also impossible for sanitation workers to monitor in real time. Therefore, there is still a risk of damage to the UPS, which affects the normal use of the equipment. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example

[0028] The present invention provides a UPS compatible with a lithium battery management system, comprising a shell 1 and a rain shelter 2 arranged on the shell 1, a sealed door 26 is arranged on the shell, a circuit board 3 is arranged in the shell 1, a plurality of components 4 are arranged on the circuit board 3, a lithium battery pack is arranged in the shell 1, an exhaust port 5 is arranged on one of the surfaces of the shell 1, a motor 6 is arranged in the exhaust port 5, a fan blade 7 is arranged at the shaft end of the motor 6, and a dustproof net 8 is arranged on the other surface of the shell 1, characterized in that each surface of the rain shelter 2 is connected to the shell 1 through a plurality of first springs 9, a lifting member is arranged at the center of the rain shelter 2, a sealing sleeve 10 connected to the inside of the shell 1 is arranged at the center of the upper part of the shell 1, the lifting member is slidably connected to the sealing sleeve 10, and a part of the lifting member extends to the inside of the shell 1;

[0029] A group of sliding holes 11 are arranged on the lifting member along the circumferential direction, a knocking member is arranged inside the lifting member, one end of the knocking member is located outside the sliding hole 11, and a top block 12 with an arc shape and a smooth surface is arranged at the bottom end of the knocking member, so that the eccentric wheel 13 can lift up the top block 12;

[0030] The motor 6 is a double-shaft variable frequency motor and an eccentric wheel 13 driving in cooperation with the top block is arranged on the other shaft end of the motor 6 .

[0031] In the implementation of the scheme, please refer to Figure 1 , 3, 9 and 10. Since the motor 6 is a dual-axis variable frequency motor, the UPS does not need high-intensity heat dissipation in the snowy winter. The speed of the motor 6 is slowed down, and the other shaft end of the motor 6 drives the eccentric wheel 13 to rotate slowly. When the snow on the awning 2 reaches a certain weight, the awning 2 drives the lifting member to move downward in the sealing sleeve 10, and the knocking member in the lifting member also moves downward until the top block 12 at the bottom of the knocking member is lifted up by the rotating eccentric wheel 13, and the other end of the knocking member hits the awning 2. The snow on the awning 2 is vibrated by the impact and slides down along the slope of the awning 2. When the weight of the snow on the awning 2 is reduced to a certain extent, it rebounds and resets under the action of the first spring 9.

[0032] It is worth pointing out that in seasons other than winter, in order to enhance the heat dissipation inside the UPS, the speed of the motor 6 is increased, and the motor 6 drives the fan blades 7 to rotate, so that a negative pressure is generated inside the UPS, and the hot air in the outer shell 1 is discharged through the exhaust port 5, and the external air flow enters the outer shell 1 through the dustproof net 8.

[0033] It is worth pointing out that a sealing door 26 is provided on the housing, so that the sealing door 26 can be opened to inspect the interior of the housing 1 or install a battery pack.

[0034] It is worth pointing out that a circuit board 3 is arranged in the housing 1, and a plurality of components 4 are arranged on the circuit board 3. A lithium battery pack is arranged in the housing 1, and a lithium battery management system is formed by the components on the circuit board 3 to control the battery pack.

[0035] In one embodiment, see Figure 4-8 The lifting member includes a lifting tube 14 slidably connected to the sealing sleeve 10, a group of sliding holes 11 are arranged on the lifting tube 14 along the circumferential direction, a knocking member is arranged inside the lifting tube 14, and a shaft sleeve 15 is arranged on the lifting tube 14, and the shaft sleeve 15 is fixed at the inner center of the awning 2.

[0036] The striking member rises and falls in the sliding hole 11 .

[0037] In a further embodiment, the upper end of the lifting tube 14 is a solid structure, and corresponding threaded holes are provided on the upper end of the lifting tube 14 and the shaft sleeve 15. The lifting tube 14 is fixed in the shaft sleeve 15 by connecting the bolts and nuts with the threaded holes, so that the bolts and nuts can be easily screwed out from the threaded holes to separate the lifting tube 14 and the shaft sleeve 15.

[0038] In one embodiment, see Figure 4 and 7 The knocking member includes a lifting rod 16 arranged in the lifting member, a group of L-shaped top rods 17 passing through the sliding hole 11 are arranged on the lifting rod 16 along the circumferential direction, a second spring 18 connected to the lifting rod 16 is arranged in the lifting member, and a top block 12 is arranged at the bottom end of the lifting rod 16.

[0039] When the lifting rod 16 is lifted up and down in the lifting member, the L-shaped top rod 17 is lifted up and down in the sliding hole 11, and the L-shaped top rod 17 knocks the rain shelter 2 when it is lifted up and down, and the lifting rod 16 drives the top block 12 to be lifted up and down when it is lifted up and down.

[0040] In one embodiment, see Figure 5 and 8 A plate groove 19 is provided on the awning 2, a fixing plate 20 is provided in the plate groove 19, the fixing plate 20 is connected to the first spring 9, corresponding threaded holes are provided on the fixing plate 20 and the plate groove 19, and the fixing plate 20 is fixed in the plate groove 19 through the connection between the threaded holes and the bolts.

[0041] By unscrewing the bolts from the threaded holes, the fixing plate 20 is separated from the plate groove 19, and combined with the separation of the lifting tube 14 and the shaft sleeve 15, the awning 2 can be easily removed from the outer shell 1, such as when the awning 2 is deformed by hail, or when it is disassembled for maintenance, and when it is shipped, it is easier to ship.

[0042] In one embodiment, see Figure 7-8 A group of protective tubes 21 are provided on the awning 2. The lower part of the protective tubes 21 is a hollow structure and the upper part is a solid structure. When the L-shaped top rod 17 is raised or lowered, the protective tubes 21 are hit to make the awning 2 vibrate, thereby avoiding direct impact on the awning 2 and protecting the awning 2.

[0043] In one embodiment, see Figure 1 , 2 11, a support plate 22 is provided in the housing 1, a group of connected battery slots 23 are provided in the support plate 22, and lithium batteries 24 are provided in the battery slots 23.

[0044] In one embodiment, see Figure 1-3 A fixing frame 25 is provided at the bottom of the housing 1 to raise the housing 1 to prevent rainwater from flooding into the UPS during the rainy season.

[0045] The method of use of the present invention is as follows:

[0046] When the snow on the awning 2 reaches a certain weight, the awning 2 sinks under pressure, and drives the lifting tube 14 to descend in the sealing sleeve 10, and the lifting rod 16 also descends, and the first spring 9 is compressed. At this time, the top block 12 contacts the eccentric wheel 13 that is driven by the motor 6 to rotate slowly, and the top block 12 is pushed up by the eccentric wheel 13, and the top block 12 drives the lifting rod 16 to move upward, the second spring 18 is compressed, and the L-shaped top rod 17 hits the protective tube 21, causing the awning 2 to vibrate. The snow on the awning 2 falls along the sloped part. When the rear eccentric wheel 13 separates from the top block 12, the second spring 18 rebounds, the lifting rod 16 and the top block 12 drop again, and then are lifted up by the eccentric wheel 13 again. This is repeated until the snow on the awning 2 is knocked off and reduced to a certain weight, the first spring 9 rebounds, driving the awning 2, the lifting tube 14, the lifting rod 16 and the top block 12 to rise, the eccentric wheel 13 cannot contact the top block 12, and the awning 2 is no longer hit.
