Problems solved by technology
[0002] The power distribution cabinet is the final equipment of the power distribution system. During the research on the heat dissipation technology of the box-type power distribution cabinet, we found that inside the box, the heat sink on the surface of the power distribution cabinet can improve the heat dissipation capacity, but the heat sink emits A large amount of heat is accumulated inside the box, and it is difficult to discharge it immediately by natural heat dissipation alone. Even if a fan is installed to extract the internal heat, the exhausting direction of the fan is single, resulting in poor heat dissipation effect and too many internal dead angles. The effect of heat dissipation. In addition, when the power distribution cabinet is in use, it often emits a very annoying buzzing noise accompanied by vibration. This noise will not only affect people's work and rest in daily life, but more seriously, it will cause living Nervous breakdown of nearby residents
[0003] In addition, the heat dissipation system in the prior art has poor heat dissipation performance for the components on the internal main board, and it is easy to accumulate heat inside. Excessive internal heat can easily cause short-circuit spontaneous combustion of internal components. Spontaneous combustion generally occurs under continuous high temperature conditions. That is, when a certain component is always in a high temperature state, if it is not cooled, spontaneous combustion is likely to occur next. In the prior art, an alarm system will be set up to detect the problem of spontaneous combustion, but the alarm can only notify the fire and not Can't stop the fire source immediately
[0004] The outdoor installation of the power distribution cabinet is mostly on a specific platform, and the platform is relatively close to the ground. Considering the complexity of the outdoor weather, in rainy weather, when there is too much water on the road, the inside of the power distribution cabinet will be flooded. Water, causing damage to internal components, so an outdoor protection equipment for power distribution cabinets based on gas laws came into being

The invention relates to the technical field of power distribution cabinets, and discloses an outdoor protective device for power distribution cabinets based on gas law, which includes a housing, the bottom of which is fixedly connected with a lifting mechanism, and the inside of the housing is fixedly connected with a support The surface of the support frame is provided with a heat dissipation port, and the bottom of the support frame is provided with an exhaust port. The inside of the support frame is movably connected with a sound-absorbing plate through a moving mechanism. There is a hollow channel to expand the heat dissipation range. If the temperature does not drop significantly, the expansion ball will continue to grow and squeeze the chain until the chain is squeezed and broken. The chain breaks off the gear surface, causing the second sound-absorbing plate on the gear surface to fall off, destroying the With the sound-absorbing structure composed of the first sound-absorbing plate, the noise cannot be eliminated. At the same time, the heat dissipation port is completely opened to improve the heat dissipation efficiency again, thereby achieving the effect of alarm and heat dissipation.
