Novel safety helmet for power construction

The invention provides a novel safety helmet for power construction and relates to the technical field of power construction devices. By means of the novel safety helmet, when objects fall from the high altitude, a danger early-warning can be provided for construction staff on the ground, so that enough time is given to the construction staff to avoid the falling objects, and the construction staff can move to the safety zone. According to the technical scheme, the novel safety helmet comprises a helmet body, ultrasonic ranging sensors, vibration devices and a control system; the ultrasonic ranging sensors are arranged on the helmet body, and detection probes of the ultrasonic ranging sensors are located on the outer side wall of the helmet body to send out ultrasonic waves to the space above the helmet body; the vibration devices are arranged in the helmet body; the control system comprises a central processing unit, an upper computer and a wireless communication module; the ultrasonic wave ranging sensors, the vibration devices and the wireless communication module are connected with the central processing unit, and the upper computer conducts information communication with the central processing unit through the wireless communication module.
