[0046] Combined with Figure 1 As shown, ventilation holes 11 are provided on the side wall of the box body 1, and the internal high-temperature gas can enter the outside through these ventilation holes 11. Setting multiple ventilation holes 11 can effectively improve the heat dissipation efficiency, reduce the temperature inside the box body 1, and thus ensure the normal operation of the device.

[0047] Combined with Figure 1 and Figure 3 As shown, a battery mounting rack 121 is provided inside the box body 1, and the storage battery 12 is installed inside the battery mounting rack 121. Heat dissipation openings 1211 are provided on the side wall of the battery mounting rack 121, which can enable the heat of the storage battery 12 to be discharged in time through the heat dissipation openings 1211, prevent heat from accumulating inside the battery mounting rack 121, effectively reduce the temperature of the storage battery 12, ensure the normal power supply of the storage battery 12, and at the same time extend the service life of the storage battery 12.

[0048] Combined with Figure 4 As shown, a limiting bottom rack 1212 is provided inside the box body 1, and the battery mounting rack 121 is arranged within the area surrounded by the limiting bottom rack 1212, and this limiting bottom rack 1212 can limit the placement position of the battery mounting rack 121.

[0049] Combined with Figures 3 to 5 As shown, battery locking units 3 are provided on both sides of the battery mounting bracket 121, and the battery locking units 3 are used to lock and fix the storage battery 12.

The side wall of the battery mounting bracket 121 is fixedly connected to the lower clamping block 32, and the lower clamping block 32 is located below the upper clamping block 312. The upper clamping block 312 and the lower clamping block 32 are provided as wedge-shaped blocks with the same shape and structure. During the downward movement of the lower clamping block 32, the inclined surfaces of the lower clamping block 32 and the upper clamping block 312 are in sliding contact.

[0051] The storage battery 12 is placed in the battery mounting bracket 121. The battery mounting bracket 121 is placed along the limit bottom bracket 1212. The upper clamping block 312 is in contact with the inclined surface of the lower clamping block 32. At the same time, the upper clamping block 312 is affected by the thrust of the lower clamping block 32 and compresses the first return spring 316. The battery mounting bracket 121 continues to move downward until the lower clamping block 32 no longer pushes the upper clamping block 312. The elastic restoring force of the first return spring 316 can drive the upper clamping block 312 to horizontally push out along the through groove 315. The upper clamping block 312 is located directly above the lower clamping block 32, completing the limit fixation of the storage battery 12.

[0052] When the storage battery 12 needs to be maintained and replaced, push the first push rod 314. The connecting block 313 drives the upper clamping block 312 to move along the through groove 315 and compresses the first return spring 316. The upper clamping block 312 and the lower clamping block 32 are disengaged from the limit connection. Then, the battery mounting bracket 121 is taken out, and the storage battery 12 can be taken out for maintenance and replacement.

The positioning telescopic rod 317 can extend or contract following the movement of the first push rod 314 to limit the movement of the first push rod 314.

[0054] As shown in combination Figures 1 to 4 In the interior of the box body 1, a transformer 13, a first circuit board 141, and a second circuit board 142 are further arranged. A temperature and humidity sensor 15 is arranged on one side of the transformer 13.

[0055] Among them, the control unit is set as a single-chip microcomputer.

Specifically, the control end of the heat dissipation unit 2 includes the control end of the servo motor 21 and the control end of the motor 26, etc. The control unit can trigger the start, stop, and speed regulation of the servo motor 21 and the motor 26. The temperature and humidity sensor 15 can monitor the temperature and humidity inside the box body 1 in real time. If the temperature and humidity exceed the set threshold, it can give an alarm in time and start the heat dissipation unit 2 to blow and dissipate heat in time, thereby reducing the temperature inside the box body 1, effectively improving the heat dissipation efficiency, and ensuring the normal operation of each structural component.

[0056] As shown in combination Figure 2 and Figure 6 In the figure, the heat dissipation unit 2 includes structural components such as an assembly shell 20, a servo motor 21, a coupling 22, a lead screw 23, a slider 24, a support block 25, a motor 26, and a fan 27.

[0057] Among them, the cylinder body end of the servo motor 21 is fixedly connected to the inner wall of the box body 1, and the output end of the servo motor 21 is connected to the end of the lead screw 23 through the coupling 22. One side of the assembly shell 20 is fixedly connected to the inner wall of the box body 1, and the other side of the assembly shell 20 is open. The lead screw 23 is horizontally arranged inside the assembly shell 20. A slider 24 is arranged on the lead screw 23. The slider 24 can move horizontally along the assembly shell 20. The slider 24 is fixedly connected to the support block 25. A motor 26 is arranged on the support block 25, and the output shaft of the motor 26 is fixedly connected to the fan 27.

[0058] The present invention uses the servo motor 21 to provide power to drive the lead screw 23 to rotate, thereby indirectly driving the fan 27 to move horizontally along the assembly shell 20, which can accelerate the air circulation inside the box body 1, enable the accumulated heat to be dissipated through the ventilation holes 11 on both sides of the box body 1, dissipate heat and cool down the inside of the box body 1 in time, avoid overheating of the storage battery 12, and ensure the normal use of the device.

[0059] As shown in combination Figures 7 to 9As shown, multiple plug openings are provided on the side wall of the box body 1. Among them, a set of plug locking units 4 is arranged in each plug opening. The plug locking unit 4 is used to lock and fasten the plug to prevent the plug from falling off or becoming loose.

[0061] The rear end of the locking housing 41 is fixedly connected to the outer side wall of the box body 1. The rear end of the locking housing 41 is open, and the opening shape is adapted to the plug, that is, the locking housing 41 does not block or interfere with the plug from being inserted into the opening. At the same time, a first horizontal sliding groove and a second horizontal sliding groove are provided at the front end of the locking housing 41. Among them, the second return spring 44 and the clamping joint 43 are arranged in the first horizontal sliding groove. One end of the second return spring 44 is connected to the bottom end of the first horizontal sliding groove, and the other end of the second return spring 44 is connected to one end of the clamping joint 43.

[0062] Combined with Figure 9 As shown, a second horizontal sliding groove is provided on one side of the first horizontal sliding groove. A transmission rod 46 and a fixing member 47 are arranged in the second horizontal sliding groove. At the same time, the end of the second push rod 45 is also arranged in the second horizontal sliding groove, and the end of the second push rod 45 is connected to one end of the transmission rod 46. The other end of the transmission rod 46 is connected to the second return spring 44 through the fixing member 47. When the second push rod 45 is pulled or pushed to move along the second horizontal sliding groove, the clamping joint 43 can extend or retract under the drive of the second return spring 44.

[0063] Combined with Figure 8 As shown, a longitudinal sliding groove is also provided at the front end of the locking housing 41. One end of the locking rack 42 is fixedly connected to the locking housing 41, and the other end of the locking rack 42 extends into the longitudinal sliding groove and can be engaged with the clamping joint 43.

[0064] When a plug needs to be inserted, first push the second push rod 45 horizontally into the second horizontal sliding groove. The second return spring 44 is compressed and drives the clamping joint 43 to move towards the bottom end of the first horizontal sliding groove. The connection between the clamping joint 43 and the locking rack 42 is released, and the locking rack 42 can be pulled out from the longitudinal sliding groove. Then, insert the plug into the inside of the locking housing 41 and into the plug opening, and place the connecting wire in the arc-shaped groove provided in the locking housing 41. Reinsert the locking rack 42 into the longitudinal sliding groove. At this time, the clamping joint 43 moves towards the locking rack 42 under the thrust of the second return spring, and the locking rack 42 and the clamping joint 43 are snap-connected to complete the limit fixation, that is, the plug connecting wire is locked and fixed, and it can also prevent the plug from loosening or falling off, etc., so as to ensure the normal use of the uninterruptible power supply device. When the plug needs to be removed, just push the second push rod 45 again to take out the locking rack 42. It is simple, convenient and efficient to use.

[0065] Combined with Figures 1 to 9 As shown, the present invention proposes an uninterruptible power supply device with a monitoring and warning function. By setting a temperature and humidity sensor 15 inside the box body 1, the device can monitor the temperature inside the box body 1 in real time and give an alarm. By setting a heat dissipation unit 2 inside the box body 1 and using a servo motor 21 to drive a fan 27 to move horizontally back and forth, the air circulation inside the box body 1 can be accelerated, and the air with a higher temperature can be blown out from the ventilation holes 11 on both sides of the box body 1 in time to dissipate heat and cool down the inside of the box body 1 in time, avoiding overheating of the storage battery and ensuring the normal use of the device. The device is also provided with a plug locking unit 4 at the plug opening. After the plug is inserted into the opening, the locking rack 42 is inserted into the longitudinal sliding groove, and the locking rack 42 is snap-connected with the clamping joint 43, so as to realize the locking and fixation of the plug and prevent the plug from falling off or loosening. The device is provided with a battery locking unit 3. During the process of placing the battery mounting rack 121 along the limit bottom rack, the lower clamping block 32 will push the upper clamping block 312 to move along the through groove 315 until the lower clamping block 32 is completely below the upper clamping block 312. At this time, the upper clamping block 312 moves along the through groove 315 to directly above the lower clamping block 32 under the elastic force of the first return spring 316, so as to complete the locking and fixation of the storage battery 12. Similarly, when the storage battery 12 needs to be replaced, push the first push rod 314 to push the upper clamping block 312 back into the through groove 315, and the storage battery 12 can be taken out and replaced, effectively improving the efficiency of maintenance and replacement of the storage battery.
