Description

Technical Field

[0001] This invention relates to an energy-saving and controllable cable trench dehumidification device. Background Technology

[0002] Power plants use various cable trenches for laying cables (power cables, control cables, optical fibers, network cables, etc.). These cable trenches are located outdoors and are covered with cable trench covers. When the cable trench covers are damaged or there is heavy rain during the rainy season, the moisture inside the cable trench may exceed the standard. It is necessary to clean the moisture inside the cable trench regularly to ensure a good environment inside the cable trench and long-term safe and stable operation of the cables. Summary of the Invention

[0003] The purpose of this invention is to provide an energy-saving and controllable cable trench dehumidification device to solve the aforementioned technical problems.

[0004] The above objectives are achieved through the following technical solutions: An energy-saving and controllable cable trench dehumidification device comprises an internally through-hole umbrella-shaped dehumidification device and a photovoltaic power generation device. The dehumidification device includes an umbrella cover and a vertical cylinder. The lower part of the vertical cylinder structure is equipped with a temperature and humidity sensing and control device to sense the humidity in the cable trench. By setting control parameters, the dehumidification system is activated when the humidity in the cable trench reaches a certain level. The middle part of the vertical cylinder structure is equipped with a series-type axial flow fan, which is controlled by the temperature and humidity control device to start and stop.

[0005] The aforementioned energy-saving and controllable cable trench dehumidification device has a photovoltaic power generation and energy storage device fixed to the top of the outer side of the umbrella cover, which provides power to the dehumidification device.

[0006] The energy-saving and controllable cable trench dehumidification device is described above, wherein the umbrella cover is a conical umbrella cover. Beneficial effects

[0007] 1. This invention involves installing an energy-saving and controllable dehumidification tool at the cable trench cover. On sunny days, a photovoltaic panel mounted on the top of the cover generates electricity, which is then sent to an energy storage device. A temperature and humidity sensor inside the dehumidification tool detects the humidity level within the cable trench and controls the start and stop of the dehumidification fan accordingly. The stored energy supplies the control and mains power to the dehumidification tool. When a certain humidity level is reached, the dehumidification fan automatically starts; when the humidity drops to a safe level, the fan automatically stops. This dehumidification tool can automatically start and stop based on real-time humidity levels within the cable trench. Furthermore, the tool is equipped with a photovoltaic panel and an energy storage device, eliminating the need for an external power source. It is particularly suitable for cable trench locations where cable installation is inconvenient, saving on cable materials and energy consumption. Attached Figure Description
