Description

A moisture-proof communication outdoor cabinet

technical field

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

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 a moisture-proof communication outdoor cabinet, which can automatically close the vents of the outdoor cabinet in rainy weather, prevent moisture from entering the cabinet, and solve the problem of damp air entering the cabinet and causing damage to internal components. The problem of corrosion damage.

A moisture-proof communication outdoor cabinet, comprising a cabinet body, the cabinet body is provided with a vent, and the inside of the vent is provided with a moisture-proof device, and the moisture-proof device includes a box body, and the upper and lower sides of the box body are opened. A slide rail is arranged horizontally in the box body, and a sealing plate is slidably arranged on the slide rail. The first spring is used to connect the sealing plate and the box body away from each other. At least one electromagnet is arranged on the side to cooperate with the iron block, the electromagnet is connected to a power supply, the power supply is connected to a water collection power switch, the other end of the water collection power switch is connected to the electromagnet, and the water collection power switch is connected to the electromagnet. The power switch includes a fixed first copper sheet, a second spring is vertically arranged beside the first copper sheet, a water collection tank is arranged on the second spring, and a second copper sheet is arranged inside the second spring, so The second copper sheet is located above the first copper sheet, and the first copper sheet is in contact with the second copper sheet when the sump collects water and descends. The vents of this outdoor cabinet are normally opened for ventilation in sunny days. When it rains, the rainwater falls into the water collecting power switch, causing the water collecting tank to drop, and the first copper piece contacts the second copper piece. At this time, the electromagnet is energized to attract and seal. The plate slides to seal the vent, so that the humid gas will not enter the cabinet in rainy days, and when the weather turns fine, the water in the sump evaporates, and the sump rises to separate the first copper sheet from the second copper sheet. At this time, the electromagnet does not stop. Power on, the sealing plate returns to its original position due to spring tension, and the vent continues to ventilate.

In the above technical solution, preferably, the sealing plate includes an outer layer of wire mesh and a desiccant layer filled therein. The sealing plate is set in this structure so that the humid air can enter the cabinet after absorbing moisture through the desiccant layer, so that the cabinet can still be ventilated to a certain extent, and at the same time, the desiccant layer can absorb the moisture in the air in the cabinet when it is not raining. Moisture keeps the air in the cabinet in a dry state all the time to prevent the air humidity from being too high. At the same time, the sealing plate is set near the vent and will perform a drying process when the air enters the cabinet.

Compared with the prior art, the present invention has the following beneficial effects: when the outdoor cabinet of the present invention is sunny, the vents are normally opened for ventilation; The copper piece is in contact with the second copper piece. At this time, the electromagnet is energized to attract the sealing plate to slide to seal the vent, so that the humid gas will not enter the cabinet in rainy days. When the weather turns fine, the water in the sump will evaporate and the sump will rise. The first copper sheet is separated from the second copper sheet. At this time, the electromagnet is not energized, and the sealing plate returns to its original position due to the tension of the spring, and the air vent continues to ventilate.

Detailed ways

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, a moisture-proof communication outdoor cabinet includes a cabinet body 1, and the cabinet body 1 is provided with a vent 2, and the vent port 2. A moisture-proof device 3 is arranged on the inner side. The moisture-proof device 3 includes a box body 31 with openings on the upper and lower sides of the box body 31. A slide rail 32 is arranged laterally inside the box body 31. A slide rail 32 is slidably arranged on the inside of the box body 31. A sealing plate 33, the first spring 34 is used to connect the sealing plate 33 and the box body 31, an iron block (not shown in the figure) is arranged in the sealing plate 33, and at least one electromagnetic The iron 35 cooperates with the iron block, the electromagnet 35 is connected with a power supply 36, and the power supply 36 is connected with a water collection power switch 4, and the other end of the water collection power switch 4 is connected with the electromagnet 35. The water collecting power switch 4 comprises a fixed first copper sheet 41, a second spring 42 is vertically arranged beside the first copper sheet 41, a water collection tank 43 is arranged on the second spring 42, and the second spring 42 A second copper sheet 44 is arranged inside, and the second copper sheet 44 is located above the first copper sheet 41. When the water collection tank 43 falls, the first copper sheet 41 and the second copper sheet 44 contacts. When the outdoor cabinet is sunny, the vents are normally opened for ventilation. When it rains, the rainwater falls into the water collecting power switch 4, so that the water collecting tank 43 descends, and the first copper sheet 41 contacts the second copper sheet 44. At this time, the electromagnetic The iron 35 is energized to attract the sealing plate 33 to slide to seal the vent 2, so that the humid gas will not enter the cabinet 1 in rainy days, and when the weather turns fine, the water in the sump 43 evaporates, and the sump 43 rises to the first copper sheet 41 Separated from the second copper sheet 44, the electromagnet 35 is not energized at this time, the sealing plate 33 returns to its original position due to the spring tension, and the vent 2 continues to ventilate.

The sealing plate 33 includes a wire mesh outer layer 331 and a desiccant layer 332 filled therein. The sealing plate 33 is arranged in this structure so that the humid air can enter the cabinet body 1 after absorbing water vapor through the desiccant layer, so that the cabinet body 1 can still be ventilated to a certain extent, and at the same time, the desiccant layer 332 can absorb moisture when it is not raining. The moisture in the air in the cabinet 1 keeps the air in the cabinet 1 in a dry state all the time to prevent the air humidity from being too high. At the same time, the sealing plate 33 is arranged near the vent 2 when the air enters the cabinet 1. One dry treatment.
