Description

Technical Field

[0001] The present application relates to the technical field of water conservancy and hydropower equipment, and more specifically, to a moisture-proof component for water conservancy and hydropower equipment. Background Art

[0002] Water conservancy and hydropower equipment are often located at the edge of water conservancy projects such as reservoirs and rivers. The surrounding environment is humid. The wiring of some electrical parts inside electrical cabinets (such as relays, air switches and PLCs, etc.) are easily corroded and rusted by humid air, affecting the safety of electrical connections.

[0003] A document with prior art announcement number CN218569529U provides a moisture-proof component for water conservancy and hydropower equipment, which relates to the technical field of moisture-proof equipment. The moisture-proof component for water conservancy and hydropower equipment includes a protective enclosure, a cover plate is installed on the top of the protective enclosure through an accordion cover, and the two sides of the bottom surface of the cover plate are connected to the two side walls of the protective enclosure through two groups of lifting components, a drying component is arranged in the middle position of the top surface of the cover plate, a ventilation pipe is inlaid and connected to one side wall of the protective enclosure, and an electric blind is arranged in the inner cavity of the ventilation pipe, the lifting component includes an electric push rod, the top end of the electric push rod is connected to the bottom surface of the cover plate through a positioning plate, and the bottom end of the electric push rod is connected to the side wall of the protective enclosure through a support plate, and the drying component includes a support plate, and a temperature and humidity sensor is arranged on one side wall of the support plate.

[0004] Although the above-mentioned prior art solutions can achieve the relevant beneficial effects through the structure of the prior art, they still have the following defects:

[0005] 1. Ventilation through the blinds, air circulation inside and outside the enclosure will inevitably cause external humid air to enter the enclosure, and the moisture-proof effect is poor;

[0006] 2. Moisture-proofing through heating. Air heating inside the enclosure cannot remove water vapor from the air. Once the heating element stops and the air cools down, water vapor condenses and corrodes electrical parts. In addition, the heating element consumes a lot of energy when working for a long time. After heating, the water conservancy and hydropower electrical parts will work in a high-temperature environment, affecting the life of the parts and even causing the parts to burn out.

[0007] Regarding the above-mentioned related technologies, the utility model inventor believes that ventilation through blinds and air circulation inside and outside the enclosure will inevitably cause external humid air to enter the enclosure, and the moisture-proof effect is poor. Moisture-proofing through heating cannot remove water vapor from the air by heating the air in the enclosure. Once the heating element stops and the air cools down, water vapor condenses and corrodes electrical parts. In addition, the heating element consumes a lot of energy when working for a long time, and after heating, the water conservancy and hydropower electrical parts will work in a high temperature environment, affecting the life of the parts and even causing the parts to burn out.

[0008] In view of this, we propose a moisture-proof component for water conservancy and hydropower equipment. Utility Model Content

[0009] 1. Technical problems to be solved

[0010] The purpose of the present application is to provide a moisture-proof component for water conservancy and hydropower equipment, which solves the problem in the above-mentioned background technology that ventilation through shutters and air circulation inside and outside the enclosure will inevitably cause external humid air to enter the enclosure, resulting in poor moisture-proof effect. Moisture-proofing through heating cannot remove water vapor in the air by heating the air in the enclosure. Once the heating element stops and the air cools down, water vapor condenses and corrodes electrical parts. In addition, the heating element consumes a lot of energy when working for a long time, and after heating, the water conservancy and hydropower electrical parts will be operated in a high-temperature environment, affecting the life of the parts and even causing the parts to burn out.
