Abstract

The utility model provides an inclination alarm, comprising a level instrument, a timer, an alarm which sends out an alarm signal according to a timer signal, an electric power source and a circuit, which are connected mutually in series. The level instrument comprises a pipe body and liquid which is arranged in the pipe body; the upper part of the pipe body is provided with a touching switch; however, the upper part of the liquid is provided with a floating electrical conduction ball which is used to match with the touching switch to turn on or turn off the circuit. When the pipe body tilts or vibrates, the electrical conduction ball disengages from the touching switch to make the circuit turn off. The timer computes the turning-off time of the circuit, when the time reaches to a certain time, the alarm alarms or sends out a signal to receivers. The utility model applies to drivers in driving and students to wear on their heads to send out a warning, when sleeping hours exceed presetting hours, swimmers to wear on their heads to send out a warning or send out a signal to receivers to tell others that someone drowns, when someone's head is under the water for a time which exceeds a presetting time or drowning and the old to wear on their shanks to make an alarm, when falling down.

Description

Tilt alarm

[technical field]

The utility model relates to a kind of warning device.

[background technology]

At present, known warning device is to have an air-bubble level usually, by the bubble in the glass tube of checking air-bubble level whether be positioned at pipe center (the top) check the device of surveying level (or vertically) whether.

[summary of the invention]

It is a kind of with the warning device of level meter as switch that technical problem to be solved in the utility model is to provide, and when level meter tilted or vibrate, according to the setting of timer time, alarm equipment alarm or emission alarm signal were given receiver, play the warning purpose.

The technical scheme that its technical matters that solves the utility model adopts: a kind of tilt alarm, the level meter, the timer, that comprise mutual series connection send the alarm of alerting signal and the circuit that a power supply is formed according to the timer signal, this level meter comprises a body and is loaded on the interior liquid of body, a contact-making switch is established in this body top, and is provided with the conducting sphere that a floating ground and contact-making switch cooperate to come closure or disconnecting circuit at liquid upper.

The beneficial effects of the utility model are, calculate the conducting sphere be located in the level meter body and the trip time of switch by timer, and when reach setting value trip time, timer will send signal to alarm, thereby alarm is given the alarm.Be applicable to: 1, wear on the driver who works, student's head, when drowsiness surpasses the time of setting, give the alarm.2, wear on swimmer's head, vexedly in the certain hour right overhead give the alarm when in water, surpassing setting-up time (drown), or the number of delivering a letter gives receiver, told the people to drown.3, wearing on old man's shank, reports to the police in the back of falling.

[description of drawings]

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is circuit theory diagrams of the present utility model.

Fig. 2 is the level meter wiring layout.

Fig. 3 is the left view of Fig. 2.

Fig. 4 is the vertical view of Fig. 2.

Fig. 5 is the level meter schematic perspective view.

[embodiment]

Please refer to Fig. 1, the utility model tilt alarm comprises a minicell 1, a level meter 2, one outer switch 3, one timers 4 of mutual series connection and the circuit that an alarm 5 is formed.

Please continue referring to figs. 2 to Fig. 5, this level one comprises a transparent tube (scheming not label), iknsulating liquid is housed in this transparent tube (schemes not label, can be pure water), the conductive plastics ball 7 that floats in this liquid, a contact-making switch 6 is established on the top of this transparent tube, when level meter 2 is vertical, conductive plastics ball 7 is positioned at the top of transparent tube, connects the both positive and negative polarity of contact-making switch 6, and this circuit is in closure state.When the transparent tube of level meter 2 tilted to certain angle or vibration, conductive plastics ball 7 departed from the transparent tube top, disconnected the contact-making switch 6 of transparent tube top, this circuit breaker.Timer 4 can calculate in the setting-up time t1 contactor trip time, and when exceeded another setting-up time t2 trip time, alarm 5 was reported to the police or emission alarm signal is given receiver (figure does not show), plays the warning purpose.Wherein, the also available hollow metal sphere of conductive plastics ball 7 substitutes.

Claims

1, a kind of tilt alarm, it comprises that a level meter of mutual series connection, a timer, send the alarm of alerting signal and the circuit that a power supply is formed according to the timer signal, this level meter comprises a body and is loaded on the interior liquid of body, it is characterized in that: a contact-making switch is established in this body top, and is provided with the conducting sphere that a floating ground and contact-making switch cooperate to come closure or disconnecting circuit at liquid upper.
