Abstract
The utility model relates to a liquefied natural gas (LNG) heavy duty truck liquid level metering device, and aims to provide the liquid level metering device applied to the LNG heavy duty truck. The liquid level metering device is capable of accurately and reliably metering and displaying an LNG cylinder liquid level value. The liquid level metering device of the LNG heavy duty truck is characterized by comprising an LNG cylinder support, a weighing metering sensor, a signal converter and an instrument displayer, wherein the weighing metering sensor is arranged between the LNG cylinder support and a frame longitudinal beam, and a signal output end of the weighing metering sensor is electrically connected with an input end of the instrument displayer through the signal converter. Preferably, the weighting metering sensor is a resistance strain sensor. A gas cylinder external weighting metering system is adopted in the LNG heavy duty truck, and therefore metering precision, metering accuracy and stability of fuel inside an LNG cylinder are improved.
Description
Technical field
The utility model relates to a kind of measuring apparatus, particularly the level gauge device in a kind of LNG heavy-duty car.
Background technology
The liquid level of LNG natural gas vehicle demonstration for a long time adopts traditional capacitance level transducer and change thereof to send display system, exist demonstration inaccurate, defectives such as measuring accuracy is low, especially there is very big instability in its measurement data of vehicle-mounted gas cylinder for relative motion, thereby the fuel operating position that can not accurately show the LNG gas cylinder, cause the user under many circumstances owing to can accurately not learn a bottle interior fuel surplus, cause in the Natural gas vehicles way phenomenon that runs out of gas to occur.The user can only pull down gas cylinder and seek gas station, or the request breakdown trailer is to gas station.Bring very big inconvenience to user's driving, simultaneously, because capacitance level gauge is embedded in gas cylinder inside, directly cause gas cylinder to be scrapped when liquid level gauge damages, directly cause after cost and operation cost to increase.
The utility model content
At deficiency of the prior art, the utility model aims to provide a kind of level gauge device that heavily blocks application at LNG, can measure and show LNG gas cylinder level value accurately, reliably.
In order to address the above problem, this kind LNG heavy-duty car level gauge device is characterized in that comprising: LNG gas cylinder support, Weighing sensor, signal converter and instrument display;
This Weighing sensor is arranged between LNG gas cylinder support and the longitudinal beam, and the signal output part of Weighing sensor is electrically connected with the input end of instrument display via signal converter.
Preferably, described Weighing sensor is resistance strain type sensor.
The beneficial effects of the utility model are: heavily block at LNG and adopt gas cylinder container external weighing system, improve the measuring accuracy of fuel in the LNG gas cylinder, metering accuracy and stability, simultaneously, increase the convenience of the installation of LNG liquid level display system, maintenance, demarcation and adjustment, reduce producer's after service cost and user's operation cost.
Description of drawings
Fig. 1 is the structural representation of LNG heavy-duty car level gauge device of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, a kind of LNG(liquefied natural gas of the present utility model, liquefied natural gas (LNG)) heavy-duty car level gauge device, it comprises: be used for installing LNG gas cylinder support 4, Weighing sensor 3, signal converter 6 and the instrument display 7 of LNG gas cylinder 5, this Weighing sensor is preferably resistance strain type sensor.
Concrete annexation is: this Weighing sensor 3 is arranged between LNG gas cylinder support 4 and the longitudinal beam 2 by bolt 1, and the signal output part of Weighing sensor 3 is electrically connected via the input end of signal converter 6 with instrument display 7.The weight signal that LOAD CELLS 3 is sensed converts via signal converter 6 that the instrument display 7 in pilothouse shows behind the level value signal to.
By between heavy truck frame longeron and LNG gas cylinder support, two that pass the Weighing sensor screw hole is installed, and with erection bolt through the inboard cushion block of longitudinal beam, longeron, Weighing sensor, cushion block and gas cylinder support with the vertical secure fixation of sensor therein earlier.Carefully connect the wire according to sensor electrical equipment elementary diagram, debug, after car load operation debugging, sensor is being carried out adjustment, to remedy the out of true owing to the gas cylinder installation site, the error of the weighing data that causes takes place to be offset in the gas cylinder container position.
Heavily block employing gas cylinder container external weighing system at LNG, improve the measuring accuracy of fuel in the LNG gas cylinder, metering accuracy and stability, simultaneously, increase the convenience of the installation of LNG liquid level display system, maintenance, demarcation and adjustment, reduce producer's after service cost and user's operation cost.
