DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0022] See Figure 1-4 A methanol GVU supply unit with a gas-liquid alarm device includes a GVU shielding box 1, which includes a hollow box body 11 and a box cover 12. The box cover 12 is detachably mounted on the box body 11. A methanol supply pump 2, a coarse filter 3, and a fine filter 4 are installed in the box body 11. Two flanges are provided at one end of the box body 11, one of which is provided with a fuel inlet 5 and the other is provided with a fuel outlet 6. The fuel inlet 5 is provided with a methanol supply pipe 13 connected thereto, and the methanol The input end of the alcohol supply pump 13 is connected to the methanol supply pipe 2 through the fuel inlet 5, and the output end of the fine filter 4 is connected to the fuel outlet 6. The top of the box body 11 is provided with a flammable liquid collection pipe 10 connected thereto, and the other end of the flammable liquid collection pipe 10 is provided with a flammable liquid alarm 9, and the top of the box cover 12 is provided with a flammable gas alarm 8; when a flammable gas leak occurs in the GVU shielding box 1, the density of the flammable gas is smaller than that of the air, such as methanol, and it will escape to the top of the GVU shielding box 1. At this time, the flammable gas installed in the box The combustible gas alarm 8 on the top of the cover 12 will sound an alarm when it detects combustible gas, and at the same time, it will feed back to the controller to control the pneumatic shut-off valve 7 to close and cut off the source; when combustible liquid leaks in the GVU shielding box 1, the combustible liquid flows along the combustible liquid collection pipe 10 installed at the bottom of the box body 11 to the combustible liquid alarm 9. The combustible liquid alarm 9 will sound an alarm when it detects combustible liquid, and at the same time, it will feed back to the controller to control the pneumatic shut-off valve 7 to close and cut off the fuel source. Preferably, the combustible liquid collection pipe 10 is connected to the collection tank, and the combustible liquid alarm is installed in the collection tank. The leaked combustible liquid is collected in the collection tank through the combustible liquid collection pipe 10 to avoid leakage to the outside world and causing safety accidents. The GVU shielding box 1 can alarm for the leakage of combustible gas or combustible liquid, and cut off the fuel source by cutting off the pneumatic shut-off valve 7, which can avoid accidents such as combustion of the leaked combustible gas or liquid, and avoid accidents such as explosion caused by large-scale accumulation of leaked combustible gas or liquid, thereby greatly improving safety.

[0023] In this embodiment, a pneumatic shut-off valve 7 is provided between the methanol supply pump 2 and the coarse filter 3. The pneumatic shut-off valve 7 is electrically connected to the flammable liquid alarm 9 and the flammable gas alarm 8 through the controller. When the flammable gas alarm 8 or the flammable liquid alarm 9 detects that there is a leakage of flammable gas or flammable liquid in the GVU shielding box 1, the signal is fed back to the controller. The controller controls the pneumatic shut-off valve 7 to cut off the connection between the methanol supply pump 2 and the coarse filter 3, thereby cutting off the fuel supply.

[0024] In this embodiment, the methanol supply pipe 13 includes an inner tube 131 and an outer tube 132. The inner tube 131 is located in the cavity of the outer tube 132, and the central axis of the inner tube 131 coincides with the central axis of the outer tube 132. A first cavity 20 is provided between the inner tube 131 and the outer tube 132. The methanol supply pipe 13 is a double-walled tube structure, wherein the inner tube 131 is a methanol delivery pipeline, which is connected to the methanol supply pump 2 to deliver methanol into the GVU shielding box 1. When the inner tube 131 of the double-walled structure of the methanol supply pipe 13 leaks, it will only spread within the first cavity 20, which can avoid the occurrence of safety accidents to a certain extent.

[0025] In this embodiment, an inert gas inlet 14 is provided on the flange corresponding to the fuel inlet 5. The inert gas inlet 14 is located on the outside of the fuel inlet 5 and is connected to the first cavity 20. An inert gas outlet 15 is provided on one side of the box body 11. A stop valve is provided on the inert gas outlet 15. By closing the stop valve, a closed cavity is formed in the GVU shielding wire 1. During repair and maintenance, inert gas can be filled into it to detect leaks. At the same time, closing the stop valve during work can prevent the fuel from diffusing outward when the fuel leaks.

[0026] Preferably, the stop valve can be an electronic stop valve, which is electrically connected to the controller; when the GVU shielding box 1 delivers fuel to the engine, the stop valve is closed, and the methanol supply pipe 13 delivers inert gas, such as nitrogen or other inert gases, into the GVU shielding box 1 through the first cavity 20, so that an inert environment is formed in the GVU shielding box. When methanol leakage occurs, it can prevent safety accidents such as explosion. When excessive fuel leakage causes excessive pressure in the GVU shielding box 1, the controller controls the stop valve to open, and the mixed gas of the leaked fuel and inert gas in the GVU shielding box 1 is discharged, which can avoid explosion after the fuel is discharged to the outside.

[0027] In this embodiment, a handle 16 is provided on the top of the box cover 12. There are two handles 16, and the two handles 16 are respectively located at both ends of the box cover 12; when the box body 11 and the box cover 12 are disassembled, it is convenient for the operator to move it away through the handles 16 at both ends of the box cover 12.

[0028] In this embodiment, a lifting ring 17 is provided on the top of the box cover 12. There are two lifting rings 17, which are respectively located at the two ends of the box cover 12 and on one side of the two handles 16, so as to facilitate lifting the GVU shielding box 1 or the box cover 12 by a crane or other lifting equipment.

[0029] In this embodiment, a bottom plate 18 is provided at the bottom of the box body 11. There are two bottom plates 18. The two bottom plates 18 are respectively installed at the bottoms of both ends of the box body 11. Both ends of the two bottom plates 18 are provided with mounting holes. The box body 11 can be detachably installed in other positions through the bottom plates 18.

[0030] In this embodiment, a connecting plate 19 is provided on the bottom plate 18, and the other end of the connecting plate 19 is connected to the side of the box body 11. A connecting plate 19 is installed at both ends of each bottom plate 18, and the two connecting plates 19 are respectively connected to the side surfaces on both sides of the box body 11, thereby enhancing the connection strength between the bottom plate 18 and the box body 11.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention. These modifications and improvements will not affect the effect of the implementation of the present invention and the practicality of the patent.
