An uninterruptible power supply device

Abstract

The invention discloses an uninterruptible power supply device, which includes an external box body, an inner cavity is arranged inside the outer box body, a gap is opened on the inner cavity, and a blocking door is connected to the gap through bolts. The inner wall of the inner cavity is provided with several mufflers and heat dissipation mechanisms, the inner wall of the inner cavity is provided with a humidity sensor and a temperature sensor, the inner top of the inner cavity is provided with an elastic pad, and the inner wall of the inner cavity is provided with an internal The box body, the outer surface of the inner box is provided with input and output interfaces. Beneficial effects: when the device is in operation, noise will be generated, and when the noise is transmitted to the gourd-shaped sound-absorbing channel, the gourd-shaped shape feature at the entrance is used to narrow the caliber of the gourd section at the entrance, thereby facilitating the concentration of sound waves from the inner cavity to the sound-absorbing channel Inner transmission, due to the shape of multiple concave and convex peaks and valleys in the middle section of the muffler channel and the bottom section of the gourd, when the sound wave passes through these places, it can be fully reflected and absorbed by the peaks and valleys in the muffler channel.

Description

An uninterruptible power supply device technical field [0001] The present invention relates to the technical field of power supplies, in particular, to an uninterruptible power supply device. Background technique The uninterruptible power supply is to connect the storage battery with the host, and convert the direct current to the host through the module circuit such as the host inverter. System equipment replaced with mains power is mainly used to supply a single computer, computer network system or other power electronic equipment such as electricity Magnetic valves, pressure transmitters, etc. provide stable and uninterrupted power supply. Under normal circumstances, the uninterruptible power supply device is in a non-working state, and only when the mains supply is abnormal Activate the uninterruptible power supply device to supply power to the load. Since the uninterruptible power supply device is often installed in a relatively concealed place, this position ...

[0004] Moreover, the shell structure of the existing uninterruptible power supply is a single-layer solid structure. If the shell is broken due to external force, the power supply body in the shell will be directly exposed, without secondary protection, and there is a potential safety hazard. , and the shell structure of the single-layer structure has almost no ability to absorb vibration, which will generate vibration when the device is running, and the vibration will affect the working stability of the uninterruptible power supply, and more noise will be generated when the device and the shell collide with each other , and is directly transmitted through the box, the sound insulation effect of the device is not good
