Description

An outdoor cabinet with a moisture-proof vent

technical field

The invention relates to an outdoor cabinet, in particular to an outdoor cabinet with a moisture-proof vent.

Background technique

In the field of communication, the outdoor cabinet is a common communication equipment installation cabinet, which is usually used to accommodate various types of telecommunication equipment, and because the telecommunication transfer box contains a lot of telecommunication equipment, it will generate a lot of heat during operation. The heat dissipation of the cabinet is usually provided with vents on the cabinet body, using the simple heat convection principle to dissipate the heat inside the cabinet body through air flow. In the humid, hot and rainy environment in the south, the outdoor cabinet has a very high humidity in the air, which is easy to corrode and short-circuit the telecommunication equipment inside the transfer box, resulting in a decrease in the life of the telecommunication equipment and the transmission quality. However, putting the telecommunication equipment in the sealed transfer box will cause poor heat dissipation, and the temperature in the sealed transfer box will easily exceed the normal working temperature, causing damage to the telecommunication equipment.

Contents of the invention

Aiming at the deficiencies in the prior art, the present invention provides an outdoor cabinet with a moisture-proof vent, which can automatically close the vent of the outdoor cabinet in a rainy environment, prevent moisture from entering the cabinet, and solve the problem of damp air entering the cabinet. The problem of corrosion damage caused by components.

An outdoor cabinet with moisture-proof vents, comprising a cabinet body, a plurality of vents are arranged on the cabinet body, and a plurality of boards are rotatably connected to the vents, and extension rods are arranged on the boards toward the inside of the cabinet body, so that The extension rod is rotatably connected with a drying plate, the drying plate includes a cavity surrounded by wire mesh, the cavity is filled with desiccant, and at least one of the plates located outside the cabinet is provided with a The opening of the accommodating slot is upward, and the cabinet below the drying plate is provided with a limiting plate. This kind of outdoor cabinet is due to the gravity of the drying plate on sunny days, the drying plate falls on the limit plate, and there are gaps between several plates for heat dissipation and ventilation. When it rains, the air becomes humid. In order to prevent the humid air from entering In the cabinet, when it rains, the storage tank will accumulate rainwater. At this time, due to the gravity of the rainwater, the plate body rotates to make the drying plate block the vents to prevent humid air from entering the cabinet. After the sun clears, the water in the storage tank Evaporation, so that due to the gravity of the drying plate, the drying plate falls to the limiting plate again, the plate body returns to its original position, and the ventilation port continues to ventilate. Adopting this vent structure can prevent humid air from entering the cabinet in rainy days, and can normally ventilate in sunny days.

In the above technical solution, preferably, the top of the cabinet body is a slope inclined to both sides of the air vent. This enables rainwater to quickly fall into the receiving tank when it rains, so that the air vent is quickly blocked by the drying plate.

In the above technical solution, preferably, a leak hole is provided at the bottom of the holding tank, and the diameter of the leak hole is less than or equal to 1 mm. A liquid leakage hole is provided on the receiving tank so that after the rain stops, the water in the receiving tank can flow out relatively quickly, so that the ventilation opening can be opened relatively quickly.

Compared with the prior art, the present invention has the following beneficial effects: when the outdoor cabinet of the present invention is sunny, due to the gravity of the drying plate, the drying plate falls on the limiting plate, and there are gaps between several plates for Heat dissipation and ventilation. When it rains, the air becomes humid. In order to prevent humid air from entering the cabinet, the storage tank will accumulate rainwater when it rains. At this time, the plate body rotates due to the gravity of the rainwater so that the drying plate will open the vent Blocking prevents moist air from entering the cabinet. After clearing, the water in the storage tank evaporates. Due to the gravity of the drying plate, the drying plate falls to the limit plate again, and the plate body returns to its original position, and the ventilation port continues to ventilate. . Adopting this vent structure can prevent humid air from entering the cabinet in rainy days, and can normally ventilate in sunny days.

detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments: Referring to Figures 1 to 4, an outdoor cabinet with moisture-proof vents includes a cabinet body 1, and the cabinet body 1 is provided with several vents 2, The air vent 2 is rotatably connected with several plates 3, and the plate 3 is provided with an extension rod 31 toward the inside of the cabinet body 1, and the extension rod 31 is rotatably connected with a drying plate 4, and the drying plate 4 includes a metal wire 41 A cavity 42 surrounded by a net, the cavity 42 is filled with a desiccant 43, and at least one of the panels 3 on the outer part of the cabinet 1 is provided with a receiving groove 32, and the receiving groove 32 opens Upward, the cabinet body 1 below the drying plate 4 is provided with a limiting plate 44 . This kind of outdoor cabinet is due to the gravity effect of drying plate 4 when sunny day, and drying plate 4 falls on the limit plate 44, and there are gaps between some plate bodies 3 for cooling and ventilating, and when it rains, the air becomes moist, in order to prevent Moist air enters the cabinet body 1, and when it rains, the accommodating tank 32 will accumulate rainwater. At this time, the plate body 3 rotates due to the gravity of the rainwater, so that the drying plate 4 will block the vent 2 to prevent moist air from entering. In the cabinet body 1, the water in the holding tank 32 evaporates after clearing, so that due to the gravity of the drying plate 4, the drying plate 4 falls to the limit plate 44 again, the plate body 3 returns to its original position, and the air vent 2 continues Ventilation, the use of this vent 2 structure can prevent humid air from entering the cabinet 1 in rainy days, and it can be ventilated normally in sunny days. At the same time, when the vent 2 is in the open state, the drying plate 4 is located in the cabinet and can 1 to dry the air to prevent corrosion damage to electrical components caused by high air humidity.

The top of the cabinet 1 is a slope 11 inclined to both sides of the vent 2 . This enables rainwater to quickly fall into the receiving groove 32 when it rains, so that the vent 2 is quickly blocked by the drying plate 4 .

When the storage tank 32 is full of water, if the water in the storage tank 32 relies on natural evaporation alone, it will take a long time for the vent 2 to be fully opened, resulting in poor heat dissipation in the cabinet body 1, thereby making the internal electrical components Working under the condition of exceeding the operating temperature may cause damage to the electrical components in the cabinet body 1. Therefore, a liquid leakage hole 33 is provided at the bottom of the receiving tank 32, and the diameter of the liquid leakage hole 33 is less than or equal to 1 mm. The diameter of the liquid leakage hole 33 The diameter can be properly adjusted according to the actual size of the holding tank 32, but not larger than 1mm. In this embodiment, the diameter of the leakage hole 33 is 1mm. A liquid leakage hole 33 is provided on the receiving tank 32 so that after the rain stops, the water in the receiving tank 32 can flow out relatively quickly, so that the vent 2 can be opened relatively quickly, and the influence on heat dissipation is minimized.
