The present invention relates to an apparatus for detecting damage to a turntable bolt, which is able to electrically detect and notify persons of damage to the turntable bolt. According to the present invention, the apparatus for detecting the damage to the turntable bolt, which is electrically connected to a bolt washer whose ground connection is released as the turntable bolt is damaged, comprises: a battery which generates and outputs a battery voltage; a buzzer which, when the battery is electrically connected, generates at least one of a preset light and a preset sound; a first relay which, when a voltage difference between an input node and a ground connection is the same as or higher than a reference value, electrically connects the battery to the buzzer; and a second relay which, when the voltage difference between the battery and the bolt washer becomes lower than the reference value, electrically connects the battery and the input node of the first relay.

    본 발명은 턴테이블 볼트의 손상을 전기적으로 검출 및 통보할 수 있도록 하는 턴테이블 볼트 손상 감지 장치에 관한 것으로, 이는 턴테이블 볼트가 손상됨에 따라 접지 상태가 해제되는 볼트 와셔에 전기적으로 연결되는 턴테이블 볼트 손상 감지 장치는, 배터리 전압을 생성 및 출력하는 배터리; 상기 배터리가 전기적으로 연결되면, 기 설정된 빛과 소리 중 적어도 하나를 발생하는 부저; 입력 노드와 접지간의 전압차가 기준치 이상이면, 상기 배터리와 상기 부저간을 전기적으로 연결하는 제1 릴레이; 및 상기 배터리와 상기 볼트 와셔간의 전압차가 기준치 보다 작아지면, 상기 배터리와 상기 제1 릴레이의 입력 노드간을 전기적으로 연결하는 제2 릴레이를 포함한다.
