Description

Technical Field

[0001] The utility model relates to a power supply waterproof device. Background Art

[0002] During outdoor construction work, emergency power supply is usually required. Emergency power supply uses dye as energy to generate electricity. The emergency power supply in the prior art has a high degree of integration. Its electrical components and generator are integrated in a machine cover. When it rains, rain falls on the generator. Since the generator is in a high temperature state, the rain will evaporate quickly. The evaporated water vapor can easily enter other electrical components, causing electrical components to malfunction after water enters.

[0003] The existing solution is mainly to improve the sealing of the electrical components themselves. However, no matter how the sealing is performed, if the rainwater problem at the source is not solved, other waterproofing can only serve as a safety measure.

[0004] There is also a technical solution, which is to unfold an umbrella above the emergency power supply. The interior of the umbrella is provided with a metal frame. In strong winds, the umbrella is easily blown over, so its effectiveness is limited. In addition, the umbrella is plug-in structured between the emergency power supply, and its own firmness is also poor.

[0005] To this end, we designed a power supply waterproof device that can provide protection above the emergency power supply and has good wind resistance. Utility Model Content
