Utility model content
For addressing the above problem, the utility model provides a kind of hand-held liquid level gauge that can flexible Application carries out traverse measurement.
The utility model solves the technical scheme that its technical matters adopts:
A kind of hand-held liquid level gauge, comprise the shell that is provided with handle, one end away from handle on shell is provided with ultrasonic probe, in shell, be provided with the circuit board being connected with ultrasonic probe and be positioned at trigger switch and the alarm appliance on circuit board, shell is provided with the button being connected with trigger switch, is also provided with the battery that is connected to provide power supply with circuit board in shell.
Be further used as the improvement of technical solutions of the utility model, alarm appliance comprises and is positioned at the display lamp that shell is stretched out in one end on circuit board.
Be further used as the improvement of technical solutions of the utility model, warning device comprises the hummer being arranged in the enclosure on circuit board.
Be further used as the improvement of technical solutions of the utility model, be positioned at handle side and be provided with battery case lid on shell, battery is installed on the bottom of battery case lid.
The beneficial effects of the utility model: when this hand-held liquid level gauge is used, hand-holdable handle withstands on container side wall through ultrasonic probe, by ultrasonic probe, launching ultrasound wave detects, container inner wall being detected has liquid to start alarm appliance, thereby determine the liquid level position of container inside, can determine liquid level, this liquid level gauge is used flexibly, can be convenient to multimetering.
Embodiment
With reference to Fig. 1~Fig. 3, the utility model is a kind of hand-held liquid level gauge, comprise the shell 1 that is provided with handle 11, one end away from handle 11 on shell 1 is provided with ultrasonic probe 2, in shell 1, be provided with the circuit board 7 being connected with ultrasonic probe 2 and be positioned at trigger switch 4 and the alarm appliance on circuit board 7, shell 1 is provided with the button 41 being connected with trigger switch 4, is also provided with the battery 8 that is connected to provide power supply with circuit board 7 in shell 1.
When this hand-held liquid level gauge is used, hand-holdable handle 11 withstands on container side wall through ultrasonic probe 2, by ultrasonic probe 2 transmitting ultrasound waves, detect, container inner wall being detected has liquid to start alarm appliance, thereby determine the liquid level position of container inside, can determine liquid level, this liquid level gauge is used flexibly, can be convenient to multimetering.
As the utility model preferred embodiment, alarm appliance comprises and is positioned at the display lamp 6 that shell 1 is stretched out in one end on circuit board 7.
As the utility model preferred embodiment, warning device is included in and in shell 1, is arranged at the hummer 5 on circuit board 7.
As the utility model preferred embodiment, be positioned at handle 11 sides and be provided with battery case lid 3 on shell 1, battery 8 is installed on the bottom of battery case lid 3.
This hand-held liquid level gauge in use, perpendicular to easy sidewall, and holds out against container side wall by ultrasonic probe by liquid level gauge, along container side wall, detects from top to bottom.
Ultrasound examination is by running into the echo of barrier reflection after continuous inspection ultrasound wave transmitting, thereby measures the mistiming that transmits and receives echo, to determine whether be positioned at container side wall check point exists liquid.
Push button 41, ultrasonic probe 2 transmitting ultrasound waves, when test does not have liquid to test point position, display lamp 6 is shown in red, and hummer 5 can not reported to the police simultaneously.
Push button 41, ultrasonic probe 2 transmitting ultrasound waves, when test has liquid to test point position, display lamp 6 is shown in green, and hummer 5 is reported to the police simultaneously.
Display lamp 6 and hummer 5, as two alarm appliances of this hand-held liquid level gauge, can use simultaneously, also can only with one, report to the police.
This hand-held liquid level gauge is easy to carry, and can test to different containers liquid level that also can Measurement accuracy solution.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and the modification that these are equal to or replacement are all included in the application's claim limited range.
