Abstract
The utility model discloses a kind of engineering truck fuel tank fuel quantity detection device, there is fuel tank (1), pedestal (2) are fixed in fuel tank (1) bottom, the bracket (3) being vertically arranged is fixed on the pedestal (2), the multiple resistive pressure sensor R1 ~ Rn being connected in series are equipped on bracket (3), the multiple resistive pressure sensor R1 ~ Rn being connected in series successively equidistantly successively decrease away from the height of fuel tank (1) bottom and are spaced 90 degree of distributions around bracket (3), and the output end of the multiple resistive pressure sensor R1 ~ Rn being connected in series connects with display circuit (4).When situations such as engineering truck jolts, anxious acceleration, anxious decelerations, each position pressure is transformed into corresponding electric signal by set resistive pressure sensor, is characterized with the concatenated electric signal of institute to oil mass, is accurately detected to realize to fuel tank fuel quantity.
Description
Technical field
The utility model relates to a kind of oil mass detection device, especially a kind of accurate, reliable, practical, safe engineering truck
Fuel tank fuel quantity detection device.
Background technique
Currently, well known motor vehicle oil tank oil mass detection device is there are many structure type, floating ball type liquid-level meter is wherein one
Kind.The detection sensor of existing floating ball type liquid-level meter has a measurement pipe, is equipped at different location from top to bottom in measurement pipe more
A tongue tube has the pick-up for installing and being sealed in the fixed end on fuel tank and connect with tongue tube in the upper end of measurement pipe
Device, connecting terminal etc. are socketed with magnetic floating ball outside measurement pipe.When magnetic floating ball changes with liquid level and is floated up and down, magnetic coupling
The contact of the cooperation tongue tube made on corresponding position is attracted or disconnects, and the all-in resistance (or voltage) of sensor is made to change,
The current signal that resistance (or voltage) signal after variation is converted into 4 ~ 20mA is exported by connecting terminal to survey by transmitter again
Measure instrument.Under motor vehicle normal operating condition compared with other fuel tank fuel quantity detection devices, floating ball type liquid-level meter has structure
Simply, the features such as debugging is convenient, good reliability, precision is high.But it if is installed on the fuel tank of road and bridge engineering vehicle, magnetic
Property floating ball also can with the jolting of road and bridge engineering vehicle, it is anxious accelerate, it is anxious slow down etc., significantly shaken up and down in fuel tank.Over range
The instant impact generated when shaking often results in that magnetic floating ball is stuck or damage, and it is short by (only one not only result in sensor service life
A month or so), added cost, and the accuracy rate of detection is seriously affected, it can not really reflect fuel tank actual oil mass.
Summary of the invention
The utility model is provided a kind of accurate, reliable, real to solve above-mentioned technical problem present in the prior art
With, safety engineering truck fuel tank fuel quantity detection device.
The technical solution of the utility model is: a kind of engineering truck fuel tank fuel quantity detection device has fuel tank, in fuel tank
Bottom is fixed with pedestal, and the bracket being vertically arranged is fixed on the pedestal, and the multiple resistive pressures being connected in series are equipped on bracket
Sensor R1 ~ Rn, the multiple height of the resistive pressure sensor R1 ~ Rn away from tank bottoms being connected in series successively equidistantly are successively decreased
And it is distributed around 90 degree of spacer support frame, the output end and display circuit of the multiple resistive pressure sensor R1 ~ Rn being connected in series
Connect.
The utility model is that the bracket being vertically arranged is fixed in fuel tank, and the multiple resistive pressures being connected in series are equipped on bracket
Sensor, height of multiple resistive pressure sensors away from tank bottoms are successively equidistantly successively decreased and are distributed around 90 degree of spacer support frame,
When situations such as engineering truck jolts, anxious acceleration, anxious decelerations, each position is pressurized by set resistive pressure sensor
Power is transformed into corresponding electric signal, is characterized with the concatenated electric signal of institute to oil mass, is accurately examined to realize to fuel tank fuel quantity
It surveys.The utility model can avoid the phenomenon that stuck magnetic floating ball present in existing floating ball type liquid-level meter or damage, have it is reliable,
The advantages that practical, safe.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Fig. 2 is the schematic block circuit diagram of the utility model embodiment.
Specific embodiment
The engineering truck fuel tank fuel quantity detection device of the utility model is as shown in Figure 1 and Figure 2, has same as the prior art
Fuel tank 1 is fixed with pedestal 2 by flange in 1 bottom of fuel tank, is fixed on the pedestal 2 and is vertically arranged and is relatively large in diameter cylindric
Bracket 3 is wound with the multiple resistive pressure sensor R1 ... R3 ... R5 ... R7 ... R9 ... being connected in series from top to bottom on bracket 3
R11 ... R13 ... R15 ... R17 ~ Rn, height of multiple resistive pressure sensor R1 ~ Rn away from 1 bottom of fuel tank being connected in series is successively
Equidistantly successively decrease and is spaced 90 degree of distributions, the output end for the multiple resistive pressure sensor R1 ~ Rn being connected in series and display around bracket 3
Circuit 4 connects.Display circuit 4 can be the display circuit of built in op processor, by the pressure signal after obtained series connection
Oil mass is converted into show.
