- a light receiving device, which is connected to the two ends of the same overhead cable and arranged relatively parallel to the light emitting device, and the light receiving device can receive the linear light emitted by the linear light emitter;

- a timer, electrically connected to the light receiving device, when the light receiving device cannot sense the linear light beam emitted by the linear light emitter, the timer counts, when the light receiving device senses again When the linear light beam emitted by the linear light emitter is detected, the timer stops counting, so as to obtain the single timing value t of the timer;

- the processor can receive the count value t sent by the timer, and compare the count value t with the set value stored in the processor, if it is greater than this value, then control the alarm device to send out Call the police.

As a further improvement of the utility model, the outer turntable is provided with inner gear teeth, the power device includes an outer gear driven by a motor, and the outer gear meshes with the inner gear teeth on the turntable.

As a further improvement of the present utility model, the light emitting device further includes a planetary disk driven by a motor to rotate and eccentrically connected to the end surface of the outer turntable, and the linear light emitter is eccentrically statically connected to the planetary disk .

As a further improvement of the utility model, the alarm device is an alarm flashing light and/or an alarm bell.

The beneficial effect of the utility model is that the utility model can detect the straightness of the cable, and when the detection result is greater than the set standard value, an alarm is sent to facilitate timely maintenance.

detailed description

The specific embodiment of the present utility model is described in further detail below.

As shown in Figure 1, the utility model includes

- The light emitting device 4, which includes an annular inner chuck 6 statically connected to the overhead cable 2 and coaxially arranged, and an annular outer turntable 8 whose inner wall is rotatably connected to the outer peripheral surface of the inner chuck 6, The outer turntable 8 is provided with a power device to drive it to rotate, and a linear light emitter 10 connected to the end surface of the outer turntable 8, the linear light emitter 10 can emit light in the same direction as the axis of the overhead cable 2. Parallel straight beams;

- The light receiving device 12, which is connected to the two ends of the same overhead cable 2 with the light emitting device 4 and arranged relatively parallel, the light receiving device 12 can receive the light emitted by the linear light transmitter 10 straight light;

- a timer, electrically connected to the light receiving device 12, when the light receiving device 12 cannot sense the linear light beam emitted by the linear light emitter 10, the timer counts, when the light receiving device 12 When the device 12 re-senses the linear light beam emitted by the linear light emitter 10, the timer stops counting, so as to obtain the single count value t0 of the timer;

- the processor can receive the count value t0 sent by the timer, and compare the count value t0 with the set value stored in the processor, if it is greater than this value, then control the alarm device to send out Call the police.

As a further improvement of the present invention, the outer turntable 8 is provided with inner gear teeth, and the power device includes an outer gear 14 driven by a motor to rotate, and the outer gear 14 meshes with the inner gear teeth on the turntable.
