In the attached drawing, 1 is an elevator short-circuit wire, and 2 is a shell of a warning device body.

Detailed Description

Embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.

As shown in figure 1, the elevator short circuit wire warning device comprises a warning device body, wherein the warning device body is installed on an elevator short circuit wire, the warning device body comprises a reset unit, an early warning unit and a power supply unit, the reset unit is electrically connected with the early warning unit, and the early warning unit is electrically connected with the power supply unit.

Further, as shown in fig. 2, the warning device body is specifically installed in a manner of being connected in parallel to the elevator short-circuit wire 1, wherein the early warning unit includes a timer, and the timer is electrically connected to the reset unit and the power supply unit respectively, and is used for timing the short-circuit duration when the elevator short-circuit wire 1 forms a path. The early warning unit further comprises a buzzer, and the buzzer is electrically connected with the timer, the reset unit and the power supply unit respectively and used for sending out alarm sound according to the timing duration of the timer so as to play a warning role.

Further, the reset unit comprises a reset switch, and the reset switch is electrically connected with the timer and the buzzer respectively and is used for controlling the buzzer and the timer so as to reset the timing process. The power supply unit comprises a battery, and the battery is electrically connected with the timer and the buzzer and is used for respectively supplying power to the timer and the buzzer. The warning device body is equipped with shell 2, and shell 2 is a rectangular box body, and reset switch, time-recorder, bee calling organ and battery are all installed inside the rectangular box body, and the size of warning device shell 2 can be set for according to actual conditions, for example, if the space on actual installation scene is narrower, can be with warning device shell 2 design for a rectangular box body that only has 1 centimetre 5 centimetres size, easy to assemble, occupation space is little.

Specifically, the elevator short-circuit wire warning device is connected in parallel to the elevator short-circuit wire 1, and when the elevator short-circuit wire 1 forms a passage, the elevator short-circuit wire warning device starts timing through a timer in the device body.
