Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a power box with the function of flooding and sealing the cavity, which solves the problem that when the power box is flooded, the power box installed in a low-lying place is easy to enter water from the heat dissipation port of the power box, resulting in a short circuit , the electricity is conducted through the water flow, which is likely to cause the danger of electric shock to passers-by

Abstract

The invention provides a power box with the function of closing a cavity in flood. The power box comprises a closed top cover, a power box body, threaded holes, a fixed base, a service door switch, connection hinges and maintenance doors. A lower end of the closed top cover is welded to an upper side of the power box body, the closed top cover is set above the fixed base, and the threaded holes and the fixed base are an integrated structure. A floating block mechanism floats upward due to buoyancy in flood, a waterproof baffle mechanism is driven to move upward to close a heat dissipation holeon the power box body, and water is prevented from flowing into the inside of the power box. When the power box is completely submerged, a small floating block on the floating block mechanism floatsto a water surface, a glass plate on the small floating block and a mercury layer reflect red light, the water is prevented from flowing into the inside of the power box to cause short circuit, the electric shock of a passing person caused by the electrical conduction of the water is prevented, a submerged position of the power box can be determined, and power workers can find and treat in time.

Description

technical field [0001] The invention relates to an electric box with the function of flooding and sealing a cavity, and belongs to the technical field of electric boxes. Background technique [0002] The tropical rainforest climate in the equatorial area, due to the tropical rainforest climate, it is rainy during the rainy season, and the long-term precipitation leads to frequent flooding in the lower parts of the equatorial area, which makes it easy for the power box installed in the lower part to leak water from the cooling vent internal. [0003] Based on the above description, the inventors found that the existing power box with the function of flooding and sealing the cavity mainly has the following deficiencies, such as: [0004] When flooded, the power box installed on the low ground is easy to get water from the heat dissipation port of the power box, resulting in a short circuit, and the electricity is conducted through the water flow, which is likely to cause the ...
