The invention relates to the field of an elevator, and particularly relates to an elevator preventing accidental movement of a compartment. The movable detection device is installed on the elevator and used for detecting the movement state of the compartment. The movable detection device comprises a detection roller, a photovoltaic receiver, a photovoltaic transmitter, a rotating shaft and a shell, wherein the detection roller is movably connected with the rotating shaft, the rotating shaft is arranged inside the shell and connected with the first side wall and the second side wall, a through hole is formed in the side part of the detection roller, the photovoltaic transmitter is connected with the first side wall, the photovoltaic receiver is connected with the second side wall, and the positions of the photovoltaic transmitter and the photovoltaic receiver correspond to the position of the through hole. An electric control system of the elevator instructs a linked stopping device to stop or not to stop the compartment according to the movement situation of the compartment, the opening situation of a brake device and the closing situation of a door lock, so that the safety accident caused by the accidental movement of the elevator can be prevented. The elevator is relatively high in safety.
