Abstract
The invention belongs to the technical field of power supplies, and particularly relates to a device for detecting the concentration of outleakage hydrogen of a hydrogen fuel power supply. The device comprises a power supply circuit, as well as a signal acquisition module, a signal processing circuit and a single chip microcomputer which are electrically connected in sequence, and further comprises a buzzer and a hydrogen tank valve switching circuit which are connected with the single chip microcomputer; the signal acquisition module comprises a supporting rack; a dust cover is arranged at the upper end of the supporting rack; and a photosensitive film, a photodiode arranged below the photosensitive film, and a wiring port connected with the photodiode by a lead wire are arranged below the dust cover. The device for detecting the concentration of outleakage hydrogen of the hydrogen fuel power supply is high in sensitivity, simple in structure, and good in monitoring effect, and is suitable for various places at which hydrogen monitoring is required; when the device detects hydrogen leakage, a valve of a hydrogen tank is switched off in the first time, so that the leakage of hydrogen is precluded from the root; the safety is ensured; and hydrogen explosion is avoided.
Description
Technical field
The invention belongs to power technique fields, be specifically related to a kind of hydrogen fuel power supply and leak outside the pick-up unit of density of hydrogen.
Background technology
Along with energy crisis constantly increases the weight of the raising with people's environmental consciousness, the cry seeking new power supply is more and more higher, and hydrogen fuel power supply is one of optimal replacer.At present, hydrogen fuel power supply, is also in the initial development stage, and the scope of its application and scene also have very large development space.But hydrogen is a kind of inflammable and explosive hazardous gas, there is very large potential safety hazard, therefore, while this clean energy resource of universal hydrogen, the explosion-proof work of hydrogen is carried out, particularly important.
Summary of the invention
The object of the invention is the problem solving hydrogen Concentration Testing around hydrogen fuel power supply.
For this reason, the invention provides a kind of hydrogen fuel power supply and to leak outside the pick-up unit of density of hydrogen, the signal acquisition module comprising power circuit and be electrically connected successively, signal processing circuit, single-chip microcomputer, also comprises the hummer be connected with single-chip microcomputer, and the hydrogen gas tank valve switch circuit be connected with single-chip microcomputer; Described signal acquisition module comprises bracing frame, and the upper end of support frame as described above is provided with dust cover, and the below of dust cover is provided with light-sensitive surface and is arranged on the photodiode below light-sensitive surface, and by Wiring port that wire is connected with photodiode.
Above-mentioned light-sensitive surface is Pd/WO3 composite sensitive film.
Above-mentioned hydrogen gas tank valve switch circuit, the on-off circuit be made up of solenoid valve or relay.
Beneficial effect of the present invention: this hydrogen fuel power supply provided by the invention leaks outside the pick-up unit of density of hydrogen, the signal acquisition module comprising power circuit and be electrically connected successively, signal processing circuit, single-chip microcomputer, also comprise the hummer be connected with single-chip microcomputer, and the hydrogen gas tank valve switch circuit be connected with single-chip microcomputer, described signal acquisition module comprises bracing frame, the upper end of support frame as described above is provided with dust cover, the below of dust cover is provided with light-sensitive surface and is arranged on the photodiode below light-sensitive surface, and by Wiring port that wire is connected with photodiode, therefore, this hydrogen fuel power supply leaks outside the pick-up unit of density of hydrogen, highly sensitive, structure is simple, monitoring effect is good, be suitable for being applied to the various place needing monitoring hydrogen, when hydrogen leak being detected, the valve of very first time closedown hydrogen gas tank, the leakage of hydrogen is broken off from root, guarantee safety, avoid causing hydrogen explosion.
Below with reference to accompanying drawing, the present invention is described in further details.

In figure: 1, light-sensitive surface; 2, photodiode; 3, Wiring port; 4, bracing frame; 5, dust cover.
Embodiment
Embodiment one:
A kind of hydrogen fuel power supply as shown in Figure 1 leaks outside the pick-up unit of density of hydrogen, the signal acquisition module comprising power circuit and be electrically connected successively, signal processing circuit, single-chip microcomputer, also comprise the hummer be connected with single-chip microcomputer, and the hydrogen gas tank valve switch circuit be connected with single-chip microcomputer; Described signal acquisition module comprises bracing frame 4, the upper end of support frame as described above 4 is provided with dust cover 5, the photodiode 2 that the below of dust cover is provided with light-sensitive surface (1) and is arranged on below light-sensitive surface 1, and by Wiring port 3 that wire is connected with photodiode 2;
This hydrogen fuel power supply leaks outside the pick-up unit of density of hydrogen, highly sensitive, structure is simple, monitoring effect is good, is suitable for being applied to the various place needing monitoring hydrogen, when hydrogen leak being detected, the valve of very first time closedown hydrogen gas tank, break off the leakage of hydrogen from root, guarantee safety, avoid causing hydrogen explosion.
Embodiment two:
Above-mentioned light-sensitive surface 1 is Pd/WO3 composite sensitive film, and light-sensitive surface 1 has the characteristic of absorption hydrogen, and being adsorbed by light-sensitive surface 1 when hydrogen and absorb, light-sensitive surface 1 refractive index changes and causes light intensity change, in a disguised form detects density of hydrogen by the value of detection light intensity; Light-sensitive surface 1, around one week of photodiode, like this when there is hydrogen adsorption in any one direction of surrounding, all can cause light intensity to change, and then cause the change of electric current in photodiode, by detecting curent change, and can indirect detection density of hydrogen; Hydrogen gas tank valve switch circuit, the on-off circuit be made up of solenoid valve or relay, clearance Single-chip Controlling closes the valve that hydrogen closes.
More than exemplifying is only illustrate of the present invention, does not form the restriction to protection scope of the present invention, everyly all belongs within protection scope of the present invention with the same or analogous design of the present invention.
