Abstract
The utility model provides a motor idling test positive and negative rotation alarm instrument, and particularly relates to a test alarm instrument which is used for direction rotation when a motor idling test is carried out. The instrument mainly solves the problems that when the motor idling test is carried out, the rotation direction of a motor driving end is difficultly judged, and errors may caused by visual inspection and wiring mode judgment. According to the utility model, an output end of a battery is respectively connected with a green flashing light emitting diode and a red flashing light emitting diode; the other end of the green flashing light emitting diode is connected with a dynamic contact in a positive and negative centrifugal switch; the other end of the red flashing light emitting diode is connected with the other dynamic contact in the positive and negative centrifugal switch; and a static contact of the positive and negative centrifugal switch is connected with the other output end of the battery. According to the utility model, through clockwise and anticlockwise rotation of a motor, the positive and negative centrifugal switch is respectively connected with the green or red flashing light emitting diode to judge positive and negative rotation, thus the rotation direction of the motor driving end is correctly, rapidly and simply judged.
Description
Technical field
The utility model relates to a kind of motor running-in test rotating warning device, relates to specifically a kind of rotary warning during for motor running-in test, judges the test warning instrument of the sense of rotation of electric machine rotation.
Background technology
At present, during motor running-in test the judgement of motor sense of rotation mainly by operating personnel's range estimation, according to two kinds of methods such as the motor modes of connection.Two kinds of decision methods all easily produce mistake, also may be subject to the impact of motor internal quality, can not reflect accurately, intuitively, fast the sense of rotation of motor, and when test operation, also have certain danger.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, and provides a kind of by vision, sense of hearing acting in conjunction, for motor running-in test rotary warning, correctly differentiate the test warning instrument of electric machine rotation sense of rotation.
Technical solution of the present utility model is: an output terminal of battery connects respectively green flashing diode and red flashing diode, the other end of green flashing diode is connected with a moving contact in positive and negative centrifugal switch, the other end of red flashing diode is connected with another moving contact in positive and negative centrifugal switch, and the stationary contact of positive and negative centrifugal switch connects another output terminal of battery.
Battery described in technical solution of the present utility model, green flashing diode and red flashing diode, and positive and negative centrifugal switch is all fixed in upper and lower casing, positive and negative centrifugal switch is fixed on the excircle in upper and lower casing.
Upper shell described in technical solution of the present utility model is provided with an alarm whistle.
The utility model is fixed on warning device by bolt the end face of machine shaft driving end, when motor turns clockwise, positive and negative centrifugal switch in warning device will be connected the power supply of green flashing diode, green flashing diode starts flashing, and is accompanied by the birdie that alarm whistle produces; When motor is rotated counterclockwise, positive and negative centrifugal switch will be connected red flashing diode, and red flashing diode starts flashing; If motor stops operating, warning device is without any flasher and caution sound.The principle of work of positive and negative centrifugal switch of the present utility model is to make the moving component motion round about when rotated of the inner conduction of switch by centrifugal force and inertia effect, and produces certain pressure thereupon, thereby realizes the connection of power supply.The visualizing that when the utility model has been realized motor running-in test, motor sense of rotation is judged, rapid, and by warning birdie, operating personnel, other staff are played to warning operation, improved the safety guarantee degree of test; And the work quality that has promoted test, has reduced labour intensity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the A-A cut-open view of alarm whistle in Fig. 1.
Embodiment
As shown in Figure 1, 2, 3, the utility model test warning instrument mainly comprises: battery 1, green flashing diode 2, red flashing diode 3, positive and negative centrifugal switch 4, upper shell 5, lower house 6, line 7, alarm whistle 8, erection bolt 9; An output terminal of battery 1 connects respectively green flashing diode 2 and red flicker diode 3, one end of green flashing diode 2 is connected with a moving contact of positive and negative centrifugal switch 4, the other end of red flashing diode 3 is connected with another moving contact of positive and negative centrifugal switch 4, and the stationary contact of positive and negative centrifugal switch 4 connects another output terminal of battery 1; Upper and lower casing 5,6 is circles, said elements is fixed in upper and lower casing 5,6, positive and negative centrifugal switch 4 is one to be made its swing arm motion connect moving contact and makes a switch of circuit turn-on by centrifugal force and inertia effect, and positive and negative centrifugal switch 4 is fixed on the excircle in upper and lower casing 5,6; On upper shell 5, be provided with an alarm whistle 8, this alarm whistle 8 can send the sound when upper and lower casing 5,6 turns clockwise, and mute when being rotated counterclockwise; During use, central shaft by upper and lower casing 5,6 is fixed on experiment electric motor rotating shaft transmission end end face to erection bolt 9 by the utility model, when motor turns clockwise, positive and negative centrifugal switch 4 is subject to inertia and centrifugal action to connect green flashing diode 2, and alarm whistle 8 sends birdie; When motor is rotated counterclockwise, positive and negative centrifugal switch 4 is subject to inertia and centrifugal action to connect red flashing diode 3, without birdie; When motor stops the rotation, the utility model flicker free, without birdie.
