Abstract

Disclosed is a power distribution cabinet, comprising a power distribution cabinet body (1) and a cabinet door hinged with a side wall on one side of the power distribution cabinet body (1), wherein the bottom of the power distribution cabinet body (1) is inclined, the lowest point of the power distribution cabinet body (1) is provided with a water collection tank (2), a layer of an oily liquid (3) is provided in the water collection tank (2), and the bottom of the water collection tank (2) is also provided with a water escape valve (4). The hot air of the power distribution cabinet body (1) condenses into water droplets after encountering a cool plate at the bottom of the power distribution cabinet body (1), and since the bottom of the power distribution cabinet body (1) is arranged to be inclined, the condensed water droplets will converge into the water collection tank (2) under the effect of gravity; and since the density of water is greater than the density of the oily liquid, the water will sink and the oily liquid (3) will seal an upper surface of water to prevent volatilization. When the water accumulates to a certain amount, a float (9) floats upward, and a bottom sealing cover (11) opens to drain under the action of a connecting rod (10); and when the liquid level falls, the sealing cover (11) is closed again, such that artificial drainage is not required and the humidity inside the power distribution cabinet is effectively maintained.

In order to solve the above technical problems, the technical solution of the present invention is: a power distribution cabinet, which is innovative in that it includes a power distribution cabinet and a cabinet door hinged to one side wall of the power distribution cabinet, and the power distribution cabinet The bottom is inclined. There is a water collecting trough at the lowest part of the power distribution cabinet. There is a layer of oily liquid in the water collecting trough. There is also a drain valve at the bottom of the water collecting trough;

A floating float is arranged above the water collecting tank, and the bottom end of the drain valve is provided with a sealing cover. A surface of the outside of the power distribution cabinet close to the water collecting tank is provided with a rotating shaft. A “7” -shaped connecting rod is arranged on the rotating shaft. Connect the other end to the sealing cap.

In some embodiments, the power distribution cabinet further includes a base. The base is fixedly disposed on the bottom of the power distribution cabinet. The interior of the base is a hollow cavity. A water inlet pipe connected to the water inlet is provided at the bottom end of the right side of the hollow cavity. The water inlet pipe communicates with the storage tank, and a control valve is provided in the water inlet pipe; a water outlet is provided at the top of the left side of the hollow cavity, and the water outlet communicates with the water storage cavity of the reservoir through the water outlet pipe; in the hollow cavity There is sound-absorbing cotton in the body, and vent holes are evenly arranged on the top of the hollow cavity. There are exhaust windows at the top of the two side walls of the power distribution cabinet. One of the exhaust windows is equipped with a humidity exhaust fan and the other A sponge block is provided in the exhaust window; a humidity controller is provided on the base, and the humidity controller is connected through the connection line controller, and the controller is connected with the control valve through the connection line.

In some embodiments, the density of the connecting rod and the end of the floating link is greater than the density of the connecting end with the sealing cover.

The utility model has the advantages that the utility model has a simple structure. A hollow cavity capable of storing water is provided under the power distribution cabinet, the temperature of the power distribution cabinet is reduced by ventilation, and the dehumidification provided on both sides of the power distribution cabinet is provided. The fan and sponge block eliminate excess moisture in the power distribution cabinet to avoid excessive humidity in the power distribution cabinet and affect the normal operation of the power distribution cabinet;

When the hot air of the power distribution cabinet meets the cold plate at the bottom of the power distribution cabinet, it will condense into water droplets. As the bottom of the power distribution cabinet is tilted, the condensed water droplets will condense into the water collecting tank under the effect of gravity. Because the density of water is greater than the density of oily liquid, the water will sink. The oily liquid will seal the upper surface of the water to prevent volatilization. When the water accumulates to a certain amount, it will float and float under the action of the connecting rod. The bottom seal cover opens to drain water. When the liquid surface goes down, the sealing cover is closed again, no artificial drainage is required and the humidity inside the power distribution cabinet is effectively maintained.
