Description

Technical Field

[0001] The utility model relates to the technical field of uninterruptible power supply, in particular to a high temperature alarm device for an uninterruptible power supply. Background Art

[0002] An uninterruptible power supply, or UPS, is an uninterruptible power supply that contains an energy storage device. It is mainly used to provide uninterruptible power supply to some equipment that has high requirements for power supply stability. The uninterruptible power supply will generate high temperature when working. The temperature of the uninterruptible power supply can be monitored through a high temperature alarm device. When the temperature of the uninterruptible power supply is too high, the high temperature alarm device will sound an alarm to remind the staff to deal with it in time to avoid loss of personnel and property.

[0003] After searching, it was found that the publication number is CN219870043U, and the name is a high-temperature alarm device for an uninterruptible power supply. The application proposed a Chinese patent with an existing announcement number of CN215068538U, which discloses a high-temperature intelligent alarm device. Although the angle of the buzzer can be easily adjusted to facilitate better alarm and avoid fire, the device is fixed with an elastic band. If the elastic band breaks, it will lead to the inability to play the role of contraction and drive the locking rod, affecting the fixation of the buzzer, and therefore does not meet the existing needs. By opening a transmission cavity inside the alarm device and rotating the transmission worm in the transmission cavity, the rotation of the buzzer alarm can be achieved under the worm transmission between the transmission worm and the transmission worm wheel, so as to achieve the angle adjustment of the buzzer alarm. Moreover, because it is driven by a worm, it has a certain self-locking property, which avoids the random rotation of the buzzer alarm, and also avoids the problem of the breakage of the elastic band affecting the angle adjustment of the buzzer alarm. At the same time, by the front of the alarm device A limit box is set at the end, and under the elastic action of the reset spring in the limit box, the limit arc block at one end of the connecting rod can be clamped and fixed to the second rotating shaft through the moving plate. After the second rotating shaft is fixed, the rotation of the transmission worm can be effectively avoided, thereby avoiding the transmission worm gear from driving the buzzer alarm to rotate, further avoiding the random rotation of the buzzer alarm. At the same time, a heat dissipation fan is set on one side of the alarm device. When the temperature sensor detects high temperature, the PLC controller not only starts the buzzer alarm but also starts the heat dissipation fan. The heat dissipation fan can extract the high-temperature gas in the uninterruptible power supply body through the heat dissipation pipe for rapid cooling, thereby avoiding damage to the uninterruptible power supply body caused by high temperature during the alarm period. However, when the application is actually used, the uninterruptible power supply body needs to power the buzzer alarm and the heat dissipation fan at the same time, which is more energy-consuming. In addition, the application also requires an electronic control system such as a PLC, which further increases the complexity of the structure, increases unstable factors, and increases the cost. Further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
