Description

Technical Field

[0001] The utility model relates to the field of underground ventilation control equipment, in particular to a damper drive control device for accurately controlling the opening and closing of a damper. Background Art

[0002] Underground ventilation is the top priority of underground production safety, and the dampers in the ventilation equipment are the hub for controlling underground ventilation. Usually, the dampers in the prior art open and close in opposite directions, and are pushed by a hydraulic or pneumatic power source. The two dampers are closed or opened in opposite directions, which plays a role in controlling the wind flow. However, this type of equipment has certain drawbacks, the most important of which is that it is impossible to strictly control the opening of the dampers using pneumatic or hydraulic power. For safety reasons, most dampers are opened and closed in a fully open or fully closed manner, that is, they are constrained by the entire movement stroke of the cylinder or hydraulic cylinder. When a certain opening is required, it needs to be completely controlled by humans, and precise operation cannot be achieved. There is currently a lack of corresponding solutions to the above problems. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a damper drive control device that can flexibly control the damper opening by means of electric power in conjunction with a speed reduction mechanism, and can accurately control the opening and closing of the damper.

[0004] The device includes a body shell, which is the assembly base of the device; the body shell is anchored to the side of the damper;

[0005] A control unit and a power unit are respectively arranged in the body shell, and a damper control crank arm is arranged on the body shell;

[0006] The control unit signal is connected to the power unit, the power unit includes a servo motor, the servo motor power is connected to the reducer, and an electric clutch mechanism is also provided between the servo motor and the reducer;

[0007] The electric clutch mechanism mentioned here refers to the existing equipment that automatically closes when powered on and automatically closes when powered off. The effect achieved by this is that the damper is controlled by the device when powered on, and automatically closes when powered off, avoiding the motor from self-locking and being unable to be pushed open manually. That is, the safety of the equipment is improved.

[0008] The speed reducer is connected to the damper control crank arm, and a mounting plate is arranged at the end of the damper control crank arm. The mounting plate is used to be mounted on the damper.

[0009] The effect achieved by this is that the control unit drives the power unit, and the motor reducer drives the damper control arm to move, so as to realize the operation of pushing or closing the damper, and the damper opening can be flexibly controlled based on the characteristics of the servo motor. The implementation method is to preset multi-level damper control opening instructions in the control unit and operate accordingly.

[0010] The beneficial effects of the utility model are as follows: the utility model can accurately control the damper opening. Compared with the pneumatic or hydraulic damper opening and closing mechanism in the prior art, the utility model is more operable and has more precise control over the ventilation volume. Moreover, the equipment takes into account power-off safety and remote control, and its applicability and safety are further improved, making it more valuable for safety promotion.
