Description

Technical Field

[0001] The utility model relates to the technical field of control equipment for tunnel fans, in particular to an automatic control box. Background Art

[0002] Tunnels are excavated and dug in mountains or underground. A large amount of dust will appear during the excavation process, so tunnel fans are needed to replace the air. Due to the small space of the tunnel, a small and sufficiently powerful special tunnel fan is needed during the dust treatment process. Gas tunnels use fans to discharge harmful gases.

[0003] In the process of controlling the fan, people usually control it by manually opening and closing the fan valve or pressing buttons to adjust the fan switch and air volume. However, in actual use, the wind speed cannot be automatically adjusted according to the situation in the tunnel. When the tunnel does not require a higher wind speed, the fan is not adjusted in time, which increases power consumption and causes energy waste. When the fan speed is low, dust particles and harmful gases in the tunnel cannot be removed in time, which easily leads to safety hazards. Therefore, an automatic control box is proposed. Utility Model Content

[0004] In view of this, the utility model provides an automatic control box to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0005] The technical solution of the utility model is implemented as follows: an automatic control box includes a control mechanism and a support mechanism;
