Abstract
The utility model relates to a monitoring device, in particular to a natural gas leakage monitoring device for double fuel automobiles. For solving technical problems, the utility model adopts the technical scheme as follows: the natural gas leakage monitoring device for double fuel automobiles is characterized in that the natural gas leakage monitoring device comprises a sensor, a controlled processing unit, an electrical switch and an early warning unit, wherein the sensor is connected onto the controlled processing unit, the controlled processing unit is used for receiving signals output by the sensor, the output end of the controlled processing unit is connected with the early warning unit, and the electrical switch is connected with the controlled processing unit and used for opening and closing the natural gas leakage monitoring device. The utility model has the advantages as follows: firstly, safety control is added to a double fuel automobile, natural gas leakage can be detected once appears, re-tightening can be performed at leakage part after inspection, and safety hazards can be eliminated; and secondly, the security of the double fuel automobile is improved, thereby enabling the design of the double fuel automobile to be improved further and flavored with humanistic cares.
Description
Technical field:
The utility model relates to a kind of monitoring device, relates in particular to a kind of dual-fuel automobile natural fuels leakage monitoring device.
Background technology:
The environment and the energy are two problems that nearly century mankind are concerned about most; the automobile pollution of high speed development has brought the high-pressure of energy source of car; a kind of hybrid vehicle is disclosed as Chinese invention patent 200810185951.5; this automobile includes reception, stores and provides the battery system and the internal-combustion engine system of electric energy; automobile can and use between the combustion engine at the use electric energy and switch; realized that the energy uses many structurings; reduced exhaust emissions simultaneously; protected environment; but this system architecture more complicated, the manufacturing price height.And the demand that dual-fuel automobile (automobile of fuel oil combustion gas) has catered to everybody, the price of its combustion gas has realized that than the low price of fuel oil the energy uses many structurings, and use cost is low.Existing market day by day increases the demand of dual-fuel automobile, dual-fuel automobile requires very high to the leakproofness of vehicle fuel steel cylinder and pressure duct, may set off an explosion if take place to reveal, and present many dual-fuel automobiles are not provided with the device that the monitoring combustion gas is revealed, and there is potential safety hazard in it.
Summary of the invention:
The utility model has mainly solved problems of the prior art, and a kind of dual-fuel automobile natural fuels leakage monitoring device is provided.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of dual-fuel automobile natural fuels leakage monitoring device, it is characterized in that: comprise sensor, controlled processing unit, electronic switch and prewarning unit, sensor is connected on the controlled processing unit, described controlled processing unit receives the signal from the output of sensor prison, and its mouth links to each other with prewarning unit, described electronic switch is connected with controlled processing unit, is used for switch natural fuels leakage monitoring device.
As a kind of preferred version of such scheme, described sensor is a pressure sensor, its be installed in automobile pressure piping, add air valve, reducing transformer, adaptor union or filter place.By the variation that checks the pressure, in case pressure is lower than normal value, signal then takes place to controlled processing unit, start prewarning unit prompting chaufeur by controlled processing unit control.
As a kind of preferred version of such scheme, described prewarning unit is the indicator lamp of a changeable colour or is a PA-system or is a read-out that it is installed on Auto Instrument desk or the CD panel.
The utility model has the advantages that 1. increase safety control one to dual-fuel automobile, reveal, can know at once, leakage place is carried out again fastening, eliminated potential safety hazard by checking the back in case natural fuels takes place; 2. improve the safety of dual-fuel automobile, made the dual-fuel automobile design further perfect, increased humane love.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a kind of structural frames view of the present utility model.
The specific embodiment:
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described.
Embodiment:
According to shown in Figure 1, the utility model is mainly by sensor 1, controlled processing unit 2, electronic switch 4 and prewarning unit 3 constitute, described sensor is a pressure sensor, it is installed in pressure piping, add air valve, reducing transformer, in adaptor union or the filter place, the sensor mouth is connected on the controlled processing unit, this controlled processing unit is a process chip, connecting prewarning unit on the controlled processing unit, prewarning unit is the indicator lamp of a changeable colour in the utility model, it is installed on the instrument desk, electronic switch is connected on the controlled processing unit, can artificially control the opening and closing of whole device.
In running car, pressure sensor detects the pressure condition at each position in real time, in case detect change value of pressure in 10～18 MPas, then pressure piping, add air valve, reducing transformer, adaptor union or filter place and reveal, pressure sensor generation signal is to the control and treatment chip, start prewarning unit and make the indicator lamp flicker, prompting chaufeur natural fuels is revealed, after chaufeur is known, and parking checking leakage place at once, then leakage place is carried out again fasteningly, eliminated potential safety hazard.
Specific embodiment described herein only is that spirit of the present invention is made casehistory.The technical personnel of the technical field of the invention can be made various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
Although this paper has used terms such as sensor, controlled processing unit, prewarning unit, electronic switch morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present invention more easily; They are construed to any additional restriction all is contrary with spirit of the present invention.
